No previous investigation has summarized findings from prospective cohort studies on the association between dietary intake of fiber, fruit, and vegetables and risk of inflammatory bowel disease (IBD). Dietary fiber and its major sources can influence the risk of IBD by modulation of the gut microbiota. This study summarizes findings from published cohort studies on the association between dietary fiber, fruit, and vegetable consumption and risk of IBD. Relevant articles published up to January 2019 were searched via PubMed, MEDLINE, Scopus, Embase, Cochrane Library, and Google Scholar. All prospective cohort studies investigating the association between dietary fiber, fruit, and vegetable intake and risk of IBD were included. Combining 7 effect sizes from 6 studies, no significant association was found between dietary intake of fiber and risk of ulcerative colitis (UC) (RR: 1.09; 95% CI: 0.88, 1.34). However, a significant inverse association was found between dietary fiber intake and risk of Crohn disease (CD) (RR: 0.59; 95% CI: 0.46, 0.74), based on 5 studies with 6 effect sizes. Pooling information from 4 studies, we found a significant protective association between dietary intake of fruit and risk of UC (RR: 0.69; 95% CI: 0.55, 0.86) and CD (RR: 0.47; 95% CI: 0.38, 0.58). We also found a significant inverse association between vegetable consumption and risk of UC (RR: 0.56; 95% CI: 0.48, 0.66) and CD (RR: 0.52; 95% CI: 0.46, 0.59). In conclusion, dietary intake of fruit and vegetables was inversely associated with risk of IBD and its subtypes. Dietary fiber intake was also inversely associated with incidence of IBD and CD, but not with UC. Further studies are warranted to examine the association of other fiber-rich foods with IBD.

Colonic malakoplakia is a rare chronic granulomatous disease that can involve many organs such as the lung, brain, pancreas, bone, adrenal glands, and genitourinary tract. The most common site of involvement outside the genitourinary tract is the gastrointestinal tract. We report a case of colonic malakoplakia who presented with unintentional weight loss, abdominal pain, and chronic diarrhea. There was a history of lupus nephritis and Sjogren disease, receiving various immunosuppressive drugs. Physical examination other than pallor was unremarkable in this patient, but colonoscopy revealed multiple polyps in the rectum with a cobblestone appearance in the cecum. The histopathological assessment showed infiltration of numerous lymphoplasma cells and neutrophils in the lamina propria, and rare Michaelis-Gutmann bodies were seen in foamy epithelioid histiocytes. These findings are suggestive of malakoplakia. We treated the patient with tetracycline, and after 3 months of follow-up, clinical improvement was achieved.

The coronavirus associated disease 2019 (COVID-19) caused by the SARS-CoV-2 virus has rapidly spread all around the world and became pandemic in March 2020. Data on liver transplantation and chronic liver disease during the pandemic has remained scarce, and there is little information on whether immunosuppressed patients are at higher risk of developing severe COVID-19 infection. This review provides information for health care providers who care for patients with liver transplantation and chronic liver diseases.

Genetic studies have illustrated that killer cell immunoglobulin-like receptor (KIR) genes could participate in various autoimmune disorders. We aimed to clarify the role of KIR genes, HLA ligands, HLA-KIR interactions, and their genotypes in inflammatory bowel disease (IBD) susceptibility. The study population was composed of 183 IBD subjects, comprising 100 ulcerative colitis (UC) patients, 83 Crohn’s disease (CD) patients, and 274 healthy subjects. Polymerase chain reaction with sequence-specific primers (PCR-SSP) was used to evaluate the absence or presence of the 15 KIR genes, 5 HLA class I ligands, and 2 pseudogenes. We did not find any significant difference in allele frequency of KIRs and pseudogenes between IBD patients and healthy controls. In the case of HLA genes, there was a significant difference in HLA-B-Bw4Thr80 frequency between UC patients and healthy controls (P=0.03, OR=0.06, 95%CI=0.008-0.4). Furthermore, we found a significant difference in HLA-C1Asn80 frequency between CD patients and healthy controls (P=0.04, OR=0.49, 95% CI=0.3-0.8). In the full-array combination of KIR genes, there was no significant frequency difference between UC patients and healthy controls, while two KIR genotypes showed a significant susceptible association with CD. Our data do not support a strong role of NK cells in IBD susceptibility, but it does not rule out a role for KIR variability in IBD patients. However, there are some protective associations such as Bw4 alleles; these associations may be due to the interaction of the alleles to TCRs rather than KIRs.

Treatment of recurrent Clostridioides difficile infection (rCDI) has emerged as an important management dilemma particularly in patients with underlying inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) has been used as a safe and highly effective treatment option for rCDI refractory to standard antibiotic therapies. The aim of this study was to report the efficacy of FMT in Iranian rCDI patients with concurrent IBD. A total of seven consecutive patients with ulcerative colitis (UC) who had experienced 3 episodes of rCDI were enrolled in this study. All patients received at least a single FMT administered during colonoscopy by direct infusion of minimally processed donor stool. Patients were followed for a minimum of 6 months for assessment of treatment efficacy and adverse events (AEs) attributable to FMT. All 7 UC patients (100%) experienced a durable clinical response to a single FMT following 2 months after the procedure. One patient received a second FMT in which a successful resolution of rCDI was ultimately achieved. No serious AEs from FMT were noted. FMT through colonoscopy was a safe, simple and effective alternative treatment approach for rCDI in patients with underlying IBD. However, its use and efficacy should be pursued in long-term prospective controlled trials.

Background: Ulcerative colitis (UC) is specified by a chronic mucosal inflammation that has a deleterious impact on the quality of life (QoL). Coenzyme Q10 (CoQ10) appears to influence disease activity by its obvious properties. Therefore, the current research intends to assess the impacts of CoQ10 on QoL, disease activity, and blood pressure in UC patients. Methods: This clinical trial performed on men and women with UC in 2017 who were attended the gastrointestinal center of Hazrat Rasool Akram Hospital and private clinic. Eighty-eight UC patients were randomly allocated to receive either CoQ10 (200 mg/day) or placebo for 8 weeks. The anthropometric parameters, blood pressure, inflammatory bowel disease questionnaire-32 (IBDQ-32) score, and the Simple Clinical Colitis Activity Index (SCCAI) score were measured pre and post-intervention. P-value

Background/Aims: A recent study revealed increasing incidence and prevalence of inflammatory bowel disease (IBD) in Iran. The Iranian Registry of Crohn’s and Colitis (IRCC) was designed recently to answer the needs. We reported the design, methods of data collection, and aims of IRCC in this paper. Methods: IRCC is a multicenter prospective registry, which is established with collaboration of more than 100 gastroenterologists from different provinces of Iran. Minimum data set for IRCC was defined according to an international consensus on standard set of outcomes for IBD. A pilot feasibility study was performed on 553 IBD patients with a web-based questionnaire. The reliability of questionnaire evaluated by Cronbach’s α. Results: All sections of questionnaire had Cronbach’s α of more than 0.6. In pilot study, 312 of participants (56.4%) were male and mean age was 38 years (standard deviation=12.8) and 378 patients (68.35%) had ulcerative colitis, 303 subjects (54,7%) had college education and 358 patients (64.74%) were of Fars ethnicity. We found that 68 (12.3%), 44 (7.9%), and 13 (2.3%) of participants were smok ers, hookah and opium users, respectively. History of appendectomy was reported in 58 of patients (10.48%). The most common medication was 5-aminosalicylate (94.39%). Conclusions: To the best of our knowledge, IRCC is the first national IBD registry in the Middle East and could become a reliable infrastructure for national and international research on IBD. IRCC will improve the quality of care of IBD patients and provide national information for policy makers to better plan for controlling IBD in Iran. (Intest Res 2019;17:330-339)

Background The optimum dosage for vitamin D supplementation has not yet been elucidated in patients with Ulcerative colitis (UC). The aim of this study was to investigate the effects of two vitamin D regimens in UC patients with vitamin D deficiency. Methods In this double blind randomized clinical trial, 50 patients with mild to moderate UC, who met inclusion criteria, received either 1000 or 2000 IU/day of vitamin D (as low dose or high dose group, respectively) for 12 weeks. Serum 25-hydroxy vitamin D (25-OHD) level, total antioxidant capacity (TAC), and Total Oxidant Status (TOS), the inflammatory bowel disease questionnaire − 9 (IBDQ-9) score and the Simple Clinical Colitis Activity Index Questionnaire (SCCAI) score were assessed before and after intervention. Results At the end of study, serum 25-OHD levels significantly increased in the high dose group (P

OBJECTIVES Protein tyrosine phosphatase non-receptor type 22 gene (PTPN22) single-nucleotide polymorphisms (SNP) have been associated with a number of different autoimmune diseases. This study aimed to investigate the association of five polymorphisms of PTPN22 gene with susceptibility to ulcerative colitis (UC) in Iran. MATERIALS AND METHODS A total of 67 patients diagnosed with UC (35 female and 32 male all under 18 years) and 93 healthy subjects were selected. The samples were genotyped for the, rs12760457, rs2476601, rs1310182, rs1217414, and rs33996649 in PTPN22 gene using real-time polymerase chain reaction (PCR) allelic discrimination TaqMan genotyping assays. RESULTS The frequencies of the rs1310182 A and G alleles, and also the AA and GG genotypes were significantly different between the patient and the control groups (p

Background and Aims: The incidence of Inflammatory bowel disease (IBD), including Crohn’s disease (CD) and Ulcerative colitis (UC), is rising in Asian populations. We undertook a cross-population study to explore whether genetic risk scores (GRS) of IBD, CD and UC could explain their occurrence, and whether they can be used to predict disease occurrence in general populations from East Asia (EA) and Central Asia (CA). Methods We studied 9,698 subjects – 4,733 IBD patients (2,003 CD; 2,730 UC) and 4,965 matched controls – who had been genotyped using Immunochip. The subjects were from three East Asian (Japan, South Korea and China) and two Central Asian populations (India and Iran). We generated GRS for each population by combining information from up to 201 genome-wide significant IBD-associated variants to summarize the total load of genetic risk for each phenotype. We then estimated the explained variance and predictability of IBD using the GRS. Results IBD GRS could explain up to 4.40% and 4.14% of IBD variance at a significant level in East Asian and Central Asian populations, respectively, but, given a prevalence of 0.01% and 0.04% for IBD, these yield limited predictive probability. GRS for CD and UC separately proved less significant than GRS for IBD. Conclusion GRS alone can explain only a limited percentage of disease occurrence (

Background: Constipation is a common disorder, and its management imposes a significant health burden. Integration of complementary and alternative medicine into the current health system may result in beneficial outcomes. Objective: This study aimed to evaluate the efficacy and safety of a Persian medicine preparation (Jalinous capsule) on functional constipation. Jalinous capsule is a combination of rose (Rosa damascena), mastic (Pistacia lentiscus), Aloe vera (Aloe barbadensis), and turpeth (Ipomoea turpethum). Methods: From January to December 2019, 126 patients aged 18 - 50 with functional constipation according to Rome IV criteria referred to Imam Khomeini hospital's gastrointestinal disease clinic were blindly randomized into "Jalinous" capsule group and placebo group for four weeks. Both groups received psyllium indeed. The patients were followed up at weeks two and four of the treatment and four weeks after the termination of the intervention. Results: Although the frequency of defecation, percentage of incomplete defecation and evacuation, straining during defecation, using manual maneuver to facilitate evacuation and defecation time showed significant improvement in both groups (P < 0.001), improvements in the intervention group were significantly more than in control group (P < 0.001). At the end of the second and fourth weeks of taking the drug and four weeks after stopping the drugs, the patients in the intervention group reported less frequent hard stool form in comparison to the patients in the control group (P < 0.001). Their overall self-reported improvement in symptoms after the treatment was significantly higher than the patients in the placebo group (P < 0.001). Adverse effects were not serious and mostly were transient. Conclusion: "Jalinous" capsule is an effective and safe treatment for functional constipation in adults, but more studies are needed to make confident conclusions.

BACKGROUND The anti-TNF drugs are shown to be highly effective in treatment of patients with moderate-tosevere inflammatory bowel disease (IBD). Here, we aimed to assess the efficacy and safety of antiTNF therapy at the national level. METHODS IBD patients aged 15 > years who received Infliximab and/or CinnoRA® between 2013 to July 2018 were identified. The data extracted from medical dossier and telephonic interview. The efficacy of therapy was defined as time to drug discontinuation or need for IBD-related surgery. The safety was assessed based on patient’s reported adverse events. RESULTS We included 315 patients. The mean age of patients was 37.2 years and 62.2% of them developed the disease before age 30 years. Involvement of masculoskeletal system was reported in 7.3% of patients. Partial and complete response to Anti-TNF therapy was seen in 67% of patients. About 16% of patients did not respond to induction therapy and 16.9% of patients lost their response to Anti-TNF during one year. No serious adverse events, serious opportunistic infection, tuberculosis and malignancies reported by patients. Two patients reported pneumonia. CONCLUSION This study for the first time in our country, provides the evidences for efficacy of anti-TNF therapy in moderate to severe IBD patients.

Background Patients with inflammatory bowel disease (IBD) are at greater risk for Clostridioides difficile infection (CDI). There remain controversial issues about the association of infliximab therapy in IBD patients and CDI. Objective The present work aimed to investigate the potential association between infliximab therapy and the risk of CDI in a group of Iranian patients with IBD. Patients and methods A total of 140 IBD patients were enrolled, their fresh stool specimens were obtained and used for C. difficile detection. The presence of toxin-encoding genes of C. difficile isolates were examined by PCR. Demographic data, frequency of defecation, antibiotic usage, and IBD therapy were recorded. Results About half of the IBD patients had a history of antibiotic usage, mostly metronidazole (11.4 %) alone, and metronidazole + ciprofloxacin (16.4 %) as drug combination. C. difficile was isolated from 17.1 % (24/140) of the IBD patients, and more than 90 % of the isolates were found to be toxigenic having genotypes of tcdA+/tcdB+ (18/22, 81.8 %), tcdA+/tcdB− (3/22, 13.6 %) and tcdA−/tcdB+ (1/22, 4.5 %). Interestingly, we only found a significant relationship between the emergence of CDI and the use of infliximab in combinations with other drugs (P = 0.023). Conclusions In conclusion, there was a considerable incidence of CDI in Iranian patients with IBD. Our study also demonstrated that anti-TNF containing regimens in combinations with other immunosuppressive medications potentially may influence susceptibility to CDI in a group of patients with underlying IBD. Furthermore, our findings recommend avoiding the prolonged use of infliximab along with other corticosteroids or immunomodulators. Further validation studies are needed to better understand the mechanisms that regulate TNF-mediated pathways in CDI pathogenesis among IBD patients.

Changes in cytokine expression have been frequently found in patients with inflammatory bowel disease (IBD). Cytokine values outside the normal range may be somewhat related to common polymorphisms within cytokine genes.The present study was designed to investigate the possible association between polymorphisms within Interleukin IL-4 and IL-10 genes and susceptibility to and clinical features of IBD.The study population was composed of 140 healthy controls and 75 patients with IBD (40 patients with Crohn's disease (CD) and 35 patients with ulcerative colitis (UC)). Genotyping was performed using polymerase chain reaction with sequence-specific primers.Higher frequencies for the C allele of IL-4-590 polymorphism (P 0.0001; odds ratio [OR], 5.68; 95% confidence interval [95% CI], 3.28-9.83) and for the T allele of IL-4-1098 polymorphism (P = 0.016; OR, 1.83; 95% CI, 1.11-3.02) were observed in the whole group of IBD patients. The IL-4-590 C allele was also significantly overrepresented when IBD patients were subdivided into CD and UC (P 0.0001; OR, 5.2-6.28). While the IL-4-1098 T allele was present at higher frequencies in patients with UC (P = 0.05; OR, 1.95), but not in CD (P = 0.09). Multiple pairwise comparisons indicated that genotypes of all polymorphisms investigated within IL-4 gene are correlated with IBD, CD, and UC. Haplotype analysis showed that the IL-4-1098/-590 TC haplotype might predispose individuals to IBD, CD, and UC whereas the IL-4-1098/-590 TT and GC haplotypes have a protective effect. On the contrary, neither allele nor genotype frequencies of IL-10 polymorphisms (IL-10-1082 A G, IL-10-592 A C, and IL-10-819 T C) were associated with IBD, CD, or UC.The present study suggests that IL-4 polymorphisms might play a role in susceptibility to IBD and its major subtypes in the Iranian population.

BACKGROUND Alopecia areata is an immune mediated inflammatory hair loss, which occurs in all ethnic and age groups, and both sexes. However no significant etiology has been known for this disease. Helicobacter pylori (H. pylori), is an organism colonized in gastric mucosa. This bacterium has been associated with certain extra-digestive dermatological conditions. The causal relationship between alopecia areata and H. pylori infection has been discussed in literature. Therefore, we conducted this study to evaluate the prevalence of H. pylori infection in patients with alopecia areata and assess the risk of this infection in patients with this disease in order to determine its potential roles in the physiopathology of this disease. METHODS Between 2014 and 2015, we prospectively studied 81 patients with alopecia areata and 81 healthy volunteers with similar age and sex. Patients without any history of H. pylori infection were included in the study and underwent urease breath test. All results were analyzed using SPSS software (version 21.0) and p value

BACKGROUND It is hypothesized that migraine may be related to inflammatory bowel disease (IBD), therefore in this cross-sectional study we evaluated the prevalence of migraine in patients with IBD. METHODS In this cross-sectional study 80 patients with IBD and 80 patients without IBD referring to gastroenterology office (Dr Daryani’s office) from May to January 2014 were evaluated regarding the prevalence of migraine, severity of migraine based on Headache Impact Test (HIT-6), and habits related to headache. RESULTS 160 participants with the mean age of 35 years were evaluated. The prevalence of migraine in the case group was significantly higher than the control (21.3% vs. 8.8%, p =0.027). Moreover duration of each attack (hours) in IBD group was significantly higher than the control group ( p

Summary Background This study was designed to determine the effects of two dosages of vitamin D supplementation on inflammatory biomarkers in patients with ulcerative colitis (UC). Methods Fifty mild to moderate active UC patients were randomly assigned to consume either 2000 or 1000 IU/day vitamin D for 12 weeks. Inflammatory biomarkers, disease activity, quality of life, anthropometric indices, dietary intakes, and physical activity were measured at the beginning and the end of the study. Results Serum level of hs-CRP decreased in both groups at the end of study, but the changes were not significantly different within and between groups. Serum level of TNF-α in the high dose group was reduced at the end of the study non-significantly (P-value = 0.289). In the low dose group, a significant increase in serum TNF-α concentration was observed (p ≤ 0.001). The changes in serum TNF-α were significantly different between two groups (p = 0.005); however, after adjusting for the effect of confounders, the significance effect was disappeared (p = 0.162). Activity of NF-κB increased in both groups while this increase was significant in the low dose group compared to the baseline (p ≤ 0.001), and to high dose group (p = 0.006). After adjustment for confounders, the difference between groups remained statistically significant (p = 0.002). Conclusion Our results indicate that 12 weeks supplementation with 2000 IU/day vitamin D prevents from systematic inflammation, while decreasing disease activity in patients with mild to moderate active UC. Further studies are needed to find the optimum dosage and duration of supplementation. This Trial was registered at IRCT.ir with number of IRCT 20100524004010N22.

Background In the absence of properly designed studies, the clinical implication of genetic findings in Inflammatory Bowel Disease (IBD) is a matter of persistent debate especially in Asian population where the prevalence of IBD including Crohn’s Disease (CD) and Ulcerative Colitis (UC) is rising. We aimed to investigate the predictability of IBD, CD, and UC by the means of Genetic Risk Score (GRS), in yet unaffected high-risk individuals from East Asia (EA) and Central Asia (CA). Methods This present study included 9,698 subjects, consisting of 2,003 CD, 2,730 UC and 4,965 countries, age and gender-matched controls, genotyped on the Immunochip array of three EA (Japan, South-Korea and China) and two CA countries (India and Iran). We generated a multi-locus GRS for each population by combining information from up to 201 known genome-wide significant IBD associated variants to summarize a total load of genetic risk for each phenotype. We estimated explained variance and predictability of IBD, CD, and UC by GRS. We shuffled the EA data into: training set including two out of the three EA populations to build a model to calculate the odds ratio (OR) for each IBD variants, and a test set including the third population for the validation of predictive model built in the training set. For Indian and Iranian populations, we used the previously estimated ORs for the Caucasian population, to build GRS and test the predictive model in these two populations. Results GRS of IBD could significantly explain up to 4.40% and 4.14% of IBD variance in EA and CA populations but given a prevalence of 0.01% and 0.04% for IBD it yields to a negligible predictive probability up to 8.8x10-4 and 5.52x10-4. GRS of CD and UC could significantly explain CD and UC to a lesser extent compared to IBD given a lower prevalence of CD and UC (figure 1). Conclusions The present study shows that genetic findings based on Trans-ethnic analyses are applicable across Asian populations. GRS alone can explain a limited percentage of disease occurrence in general population (

Background: The extent of antibiotic resistance among Helicobacter pylori strains influences current clinical therapeutic regimens in each region. Objectives: This cross-sectional study aimed to determine the resistance property and minimum inhibitory concentration (MIC50-90) of Helicobacter pylori strains toward metronidazole, clarithromycin, and ciprofloxacin in patients with distinct gastric histopathological changes in Tehran, Iran. Methods: This study was conducted on 170 patients suffering from gastric complications in three hospitals in Tehran from October 2014 until March 2015. Two separate biopsy samples were collected from each patient and used for pathological and microbiological examinations. Antimicrobial susceptibility tests were performed by agar dilution method according to the CLSI guidelines. The MIC values and susceptibility to varying concentrations of metronidazole (4 to 64 µg/mL), ciprofloxacin (0.5 to 16 µg/mL), and clarithromycin (0.25 to 16 µg/mL) were determined based on EUCAST recommendations. Results: Our results indicated the infection with H. pylori in a frequency of 32% (55/170) among the study patients (female, 51% and male, 49%). Endoscopic findings indicated that 42% of the patients suffered from peptic ulcers, 33% from duodenal ulcers, and 25% with a non-ulcer disease. Pathological findings indicated 58% of the patients had chronic gastritis, 33% had active chronic gastritis, and 9% suffered from intestinal metaplasia. In terms of antibiotic susceptibility, nearly 76.3%, 49%, and 45.5% of the strains were resistant to metronidazole, clarithromycin, and ciprofloxacin, respectively. The MIC values at which the growth of 50% and 90% of the strains was inhibited (MIC50-90) were 32 - 64 µg/mL for metronidazole, 0.5 - 16 µg/mL for clarithromycin, and 2 - 16 µg/mL for ciprofloxacin. Conclusions: The overall resistance levels were relatively high among the study patients. Accordingly, the administration of other anti-Helicobacter drugs, as well as more appropriate therapeutic regimens based on laboratory results, is recommended in patients with a history of treatment failure.

Eradication failure of Helicobacter pylori infection could play a causal role in progression of gastric disorders. In this study, infection with H. pylori was followed in gastric biopsies of symptomatic adult patients at two phases during 1-year period. Analyses were done to show association of therapeutic regimens with the refractory infection, changes in sequence types (STs) and minimum inhibitory concentration (MIC) values, and progression of histopathological changes. Infection with H. pylori was confirmed in 32.3% (57/170) of the patients. Persistent infection with H. pylori was confirmed in 14 out of the 25 patients (56%) who participated at the second phase of the study. A difference between primary and secondary resistance rates to clarithromycin (49% vs 64.3%), metronidazole (76.36% vs 100%), and ciprofloxacin (45% vs 57.1%) was detected. Although the re-emerged strains in patients with refractory infection did not show alteration in STs, their MIC50 values showed twofold increases for clarithromycin and ciprofloxacin. While ciprofloxacin containing regimens were more successful, failure of metronidazole containing regimens was detected in 77% of the patients. Consequently, inappropriate medication has an impact on refractory H. pylori infection, which could cause to a rise in resistance levels to antibiotics and progression of pathological disorders.

BACKGROUND According to recent studies comparing magnetic resonance enterography (MRE) with ileocolonoscopy for assessing inflammation of small bowel and colonic segments in adults with active Crohn's disease (CD), we aimed to compare the accuracy of these two diagnostic methods in Iranian population. METHODS During 2013-2014 a follow-up study was done on 30 patients with active CD in a gastroenterology clinic affiliated to Tehran University of Medical Sciences. MRE and ileocolonoscopy were performed for all the patients. All statistical analyses were performed using SPSS (version 18) and p-value

Liver cirrhosis is one of the main causes of mortality and morbidity worldwide. Health-related quality of life in cirrhotic patients is affected by the disease's complications. The purpose of this article was to describe the experiences of individuals with liver cirrhosis during critical illness. The aim was to investigate the disease experiences of liver cirrhosis. The authors conducted a phenomenological qualitative study, using a Colaizzi's seven-step method. Ten participants with liver cirrhosis participated in in-depth interviews. The data from this analysis were transformed into 119 codes, 11 subthemes, and 4 main themes including (1) confronting tension, (2) needs, (3) spirituality, and (4) interaction and effective communication. Findings could be used as a basis for information and emotional and social support interventions, as these can be effective in promoting adjustment to complications of cirrhosis by suitable interventions. Adequate adjustment through adaptation leads to successful completion of treatment and improved quality of life.

Background: Inflammatory bowel disease (IBD) mostly comprised of Crohn’s disease (CD) and ulcerative colitis (UC) is a condition arising from the combined effects of genetic, environmental, and immunological factors. IBD is associated with inflammation and altered cytokine profile. Objective: This study was aimed at assessing the association between T helper type 1 (Th1) cytokine polymorphisms (interferon gamma [IFN-γ] +874 A/T, interleukin-12 [IL-12] –1188 A/C, IL-2 –330 G/T, IL-2 +166 G/T) and susceptibility to and clinical features of IBD. Methods: The study population was composed of 75 IBD patients (40 CD patients and 35 UC patients) and 140 healthy controls. Genotyping was performed using polymerase chain reaction with sequence-specific primers. Results: The A allele of IFN-γ +874 polymorphism was overrepresented in the whole population of patients with IBD (OR 1.63; 95% CI 1.08–2.47; p = 0.020) and as well in the subpopulation of patients with CD (OR 2.14; 95% CI 1.26–3.63; p = 0.004), but not in UC. Multiple pairwise comparisons indicated that genotypes of single nucleotide polymorphisms (SNPs) within the IL-2 and IFN-γ genes are correlated with IBD, CD, and UC, while neither allele nor genotype frequency of th1 IL-12 –1188 polymorphism was associated with IBD, CD, or UC. Haplotype analysis also revealed that the presence of IL-2 –330/+166 TG haplotype versus the remaining haplotypes (GG, TT, and GT) is a protective factor against IBD (OR 0.62; p = 0.046). Conclusions: The present study reports (for the first time) significant associations between SNPs within the IFN-γ and IL-2 genes and IBD.

Background & Aim: Recent studies have suggested the therapeutic effect of antimicrobial agents on primary sclerosing cholangitis (PSC). Therefore, we aimed to evaluate the efficacy of oral vancomycin in patients with PSC. Method: A triple blinded, randomized, placebo-controlled trial was performed on 29 patients (2015-2016) in the Imam Khomeini Hospital, Tehran, Iran (NCT02605213). Patients were divided into two groups by simple randomization method: placebo 11 (37.9%)/vancomycin 18 (62.1%) and were treated with oral vancomycin (125 mg, four times a day) for 12 weeks. All patients in both groups simultaneously underwent treatment with ursodeoxycholic acid (UDCA, 300 mg, three times a day) before and during the study. Patients’ laboratory data and clinical symptoms were recorded at the beginning, first and third month after starting treatment, and the response to treatment was analyzed. Results: 29 patients with a mean age of 36.27±10.60 years were included in the study. Primary endpoints were accomplished in the vancomycin group showing a significant decline in the mean level of PSC Mayo risk score (decrease rate 3rd month – baseline = -322.03%, p=0.026) during follow up time. Moreover, the analysis of the level of alkaline phosphatase (ALP) in the vancomycin group showed a significant decrease in the third month of treatment as compared to its level in the first month (mean difference 3rd month -1st month = -142.92, Decrease rate= -18.24%, p=0.02). Among secondary endpoints, erythrocyte sedimentation rate (p=0.005), gamma-glutamyl transpeptidase (p=0.02) and patients’ symptoms including fatigue, pruritus, diarrhea and anorexia showed a significant decrease in the vancomycin group. Conclusion: This study demonstrated an acceptable efficacy of vancomycin in the treatment of PSC.

The imaging of hepatocellular carcinoma (HCC) is challenging and plays a crucial role in the diagnosis and staging of the disease. A variety of imaging modalities, such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear medicine are currently used in evaluating patients with HCC. Although the best option for the treatment of these cases is hepatic resection or transplantation, only 20% of HCCs are surgically treatable. In those patients who are not eligible for surgical treatment, interventional therapies such as transcatheter arterial chemoembolization (TACE), percutaneous ethanol injection (PEI), radio-frequency ablation (RFA), percutaneous microwave coagulation therapy (PMC), laser ablation or cryoablation, and acetic acid injection are indicated. In this paper, we aimed to review the evidence regarding imaging modalities and therapeutic interventions of HCC.

BACKGROUND/AIMS: As a common gastrointestinal (GI) disorder, irritable bowel syndrome (IBS) has been reported to be associated with some psychological and neurological factors. This study aimed to evaluate the prevalence rate of restless legs syndrome (RLS) in a sample of IBS patients and to compare this prevalence with that of matched healthy controls. METHODS: This prospective comparative study was conducted in Tehran, Iran during 2010-2011. Based on the Rome III criteria, a total number of 225 definite IBS patients and 262 age- and sex-matched healthy controls were recruited in the final assessment to compare the prevalence rate of RLS between the 2 groups. RESULTS: RLS was significantly more frequent in IBS group (25.3% vs 6.5%, P < 0.001) which led to an odds ratio (OR) of 4.89 (95% CI, 2.75-8.70). IBS patients with co-morbid RLS significantly suffered more from stomach pain (96.5% vs 86.3%, OR = 4.36 [95% CI, 1.00-19.12]), nausea (40.4% vs 21.4%, OR = 2.48 [95% CI, 1.30-4.73]) and vomiting (10.5% vs 2.4%, OR = 4.82 [95% CI, 1.31-17.76]). CONCLUSIONS: By enrolling a considerable number of IBS patients and healthy controls, our study showed a significantly higher prevalence of RLS in IBS patients. Surprisingly, a higher prevalence rate of RLS was also accompanied with a more severe discomfort and stomach pain in IBS patients. It seems that screening patients with IBS for RLS may lead to greater identification of RLS and improved treatment for both conditions.

Context: Hepatitis C virus (HCV) infection is a major public health issue worldwide, including Iran. The new direct-acting antiviral agents (DAAs) with high efficacy have changed the landscape of HCV treatment. This guideline provides updated recommendations for clinical management of HCV infection in Iran. Evidence Acquisition: The recommendations of this guideline are based on international and national scientific evidences and consensus-based expert opinion. Scientific evidences were collected through a systematic review of studies that evaluated efficacy and safety of DAA regimens, using PubMed, Scopus and Web of Science. Expert opinion was based on the consensus of Iran Hepatitis Scientific Board (IHSB) in the 3rd national consensus on management of Hepatitis C in Iran, held on 22nd of July 2016. Results: Pegylated Interferon alpha (PegIFN), Ribavirin (RBV), Sofosbuvir (SOF), Ledipasvir (LDV) and Daclatasvir (DCV) are currently available in Iran. Pre-treatment assessments include HCV RNA level, HCV genotype and resistance testing, assessment of liver fibrosis, and underlying diseases. In HCV genotype 1 and 4, DCV/SOF and LDV/SOF are recommended. In HCV genotype 2, SOF plus RBV and in HCV genotype 3, DCV/SOF is recommended. Additional care for underlying diseases should be considered. Conclusions: Affordable new HCV treatment regimens are available in Iran, providing an opportunity for HCV elimination. Recommendations provided in this current national guideline can facilitate evidence-based management of HCV infection.

BACKGROUND This study is the first study to evaluate the nonadherence rate and reasons of same patient with inflammatory bowel disease (IBD) in Iran. METHODS During 9 months, 500 patients with IBD were enrolled in the study. Patients were interviewed about their nonadherence behaviors. Factor analysis was used to analyze the collected answers. RESULTS The overall rate of nonadherence was 33.3% (27.6% intentional nonadherence and 5.7% unintentional nonadherence). 33.6% of the patients had at least one relapse after discontinuing treatment. The most frequent reason for intentional nonadherence was discontinuing the treatment after recovering from symptoms (42.7%). The most frequent reason for unintentional nonadherence was forgetfulness (5.2%). 19.8% of the patients did not visit their gastroenterologist on time and they purchased drugs from the drugstore. These patients reported that their clinics were too far and difficult to access. There was no significant relationship between nonadherence and demographic variables. CONCLUSION Multiple reasons are suggested as factors of medication nonadherence and they seem to be different among different populations. Determining these possible reasons, could lead to finding suitable strategies to overcome or reduce them.

The rising concerns for future health burden of hepatitis C virus (HCV) in global scale has continuously encouraged preventing measures particularly public awareness programs. There is an increasing necessity for allocating HCV awareness issues in public scope, especially for high risk populations and patients. Proper knowledge of health care professionals and treating physicians and their attitude with regard to hepatitis C management is also crucial. Achieving this can be a constructive step forward in controlling and hopefully eradicating hepatitis C virus in our community. Having a clear scientific grasp on treatment options and protocols, the concept of “CURE” achievement in hepatitis C and the future hopes in enhancing virological response with the coming direct antiviral agents can significantly add to the current practices of treating hepatitis C. This scientific report paper outlines the insights communicated at the HCV symposium during the 4th Tehran Hepatitis Congress, November 2011, Tehran, Iran.

Background/Aims Irritable bowel syndrome (IBS) is a widespread chronic health condition which is significantly more prevalent in women. We conducted a gender difference analysis by comparing findings of men and women to determine whether any significant differences exist or not. Methods This single-center study was conducted in Tehran, Iran during 2009-2010. IBS was diagnosed on the basis of Rome III criteria. A simple "10 point" objective questionnaire was used. Results A total number of 144 IBS patients including 44 (30.6%) males and 100 (69.4%) females with the mean age of 37.50 ± 11.50 years, were assessed. The only differently observed symptom was nausea which was significantly more prevalent in females (49% vs 18.2%, P < 0.001). The commonest subtype of IBS in male patients was diarrhea predominant IBS (38.6%); while, constipation predominant IBS was the most frequent type among females (38%). Moreover, the frequency of loose, mushy or watery stools within the last 3 months was significantly higher among males (2.11 ± 1.67 vs 1.37 ± 1.50, P = 0.009). Conclusions We report that gender is important in IBS. Although qualitative comparison of different subtypes of IBS between male and female failed to meet the statistically significant level, the answers to the corresponding questions of ROME III IBS module suggest the higher prevalence of bowel movements and looser stool in males. Moreover, nausea was reported more often by females.

Hepatitis C remains as an important health problem worldwide. Hepatitis C treatment, especially among patients infected with HCV genotype 1 who are considered difficult to treat, is a high priority for health policy-makers. PegInterferon alfa instead of Interferon and ribavirin combination therapy has been accepted as the standard treatment regimen for hepatitis C patients; however, only 50% of patients infected with HCV genotype 1 achieve a sustained virological response. Published data from various clinical trials of protease inhibitors suggest that new therapeutic regimens may increase the chances of a successful response in patients infected with HCV genotype 1. Triple therapy that includes boceprevir has been shown to result in high rates of sustained virological response in both naive and experienced patients with HCV genotype 1 infection. In this review, we have summarized the results obtained with this new regimen and have attempted to provide a guideline for the treatment of patients in Iran, with emphasis on cost and the occurrence of adverse events.

Some patients with non-alcoholic fatty liver disease have no obesity-related etiologies. Celiac disease could potentially present with elevated liver enzymes and chronic liver disease. The aim of this study was to evaluate the prevalence of celiac disease among patients with non-alcoholic fatty liver disease.Three hundred sixteen patients defined as non-alcoholic fatty liver disease based on elevated transaminases, liver ultrasound and/or liver biopsy were enrolled. Body mass index, waist circumference and symptoms were recorded. All were tested for recombinant IgA anti-tissue transglutaminase antibody and total IgA level. In patients with positive serology for anti-tissue transglutaminase, IgA class endomysial antibody values were determined with a commercially available indirect immunofluorescence method, and then endoscopy with duodenal biopsies was performed.The mean age of patients was 40.56±11.48 years and 50.9% were female. Celiac disease was confirmed in 7 patients (2.2%). Of these, all had body mass index between 18.37 and 26.91 kg/m². Celiac disease was more commonly diagnosed among non-alcoholic fatty liver disease patients with body mass index27 kg/m² compared to patients with body mass index27 kg/m² (5.83% vs. 0%; p=0.001).The prevalence of celiac disease among patients with non-alcoholic fatty liver disease is significantly higher than what was previously reported in the general population of Iran; thus, screening for celiac disease in these patients is reasonable, particularly in patients with body mass index27 kg/m².

The NOD2 gene is known to have a strong association with Crohn's disease, but different trends were reported in occurrence of NOD2 variants in distinct ethnicities. The aim of this study was to assess all exonic sequences of the NOD2 gene in Iranian Crohn's disease patients and healthy controls to identify any existing variation and evaluate their association with Crohn's disease.A total of 90 non-related Crohn's disease patients and 120 sex- and age-matched healthy controls of Iranian origin were enrolled in this study. The participants were referred to a tertiary center in a 2-year period (2006-2008). The exonic regions of the NOD2 gene were amplified by polymerase chain reaction and evaluated by direct sequencing.A total of 21 sequence variations were identified among all exonic regions of the NOD2 gene, of which eight had an allele frequency of more than 5%. Eight new mutations (one in exon 2 and seven in exon 4) were observed. The three main variants (R702W, G908R, and 1007fs) showed allele frequencies of 13.3%, 2.2%, and 1.7%, respectively. Three new variations (P371T, A794P, and Q908H) and R702W mutation were significantly more frequent in Crohn's disease patients compared to controls.Eight novel mutations were identified in the NOD2 exons, but the pathophysiological importance of these variants remains unclear. Iranian patients with their different genetic reservoirs may demonstrate some novel characteristics for disease susceptibility.

Context Hepatitis C virus (HCV) infection is a major cause of liver-morbidity and mortality among patients with thalassemia. Peginterferon plus ribavirin is currently the recommended therapy for hepatitis C infection in patients do not have thalassemia, but using ribavirin in patients with thalassemia is restricted due to its hemolytic effect. To evaluate the efficacy and safety of adding ribavirin to peginterferon or interferon, authors performed a systematic review on the available literatures. Evidence Acquisition Trials were identified through electronic database, manual searches of journals and bibliographies and approaching authors of trials. Randomized trials that enrolled patients with a diagnosis of thalassemia and chronic hepatitis C infection treated with interferon or peginterferon with or without ribavirin were included. Two investigators independently evaluated the trials for inclusion criteria, risk of bias and data extraction. The primary outcomes were sustained virological response (SVR), liver-related morbidity, mortality and adverse events. The odds ratios from each trial were calculated individually and in the subgroup analysis of trials. Data were analyzed with fixed-effect model. Results Three randomized clinical trials with 92 patients were included. All three trials had unclear risk of bias. Compared with peginterferon monotherapy, adding ribavirin to peginterferon had significant beneficial effect on sustained virological response (OR = 3.44, 95% CI: 1.18 - 10.06). There was no significant difference between combination therapy and monotherapy in the end of treatment achievement response. Other than about 30% increase in blood transfusion due to anemia that returned to normal level 2 - 3 months after treatment, there was no significant increase in side effects followed by adding ribavirin to pegylated interferon (Peg-IFN). Data were insufficient to determine the impact of genotype, viral load and age on the response to treatment. Conclusions Compared with monotherapy, adding ribavirin to treatment is more effective in removing hepatitis C virus from the bloodstream in patients with thalassemia, it is also more effective in reducing the relapse rate after treatment. Except the increase in blood transfusion, there was no significant increase in side effects followed by adding ribavirin.

Patients with inflammatory bowel disease (IBD) are at increased risk of developing osteopenia and osteoporosis. The aim of the study was to investigate the prevalence of decreased bone density and related risk factors in Iranian IBD patients. A total of 126 ulcerative colitis (UC) and 39 Crohn's disease (CD) patients were enrolled. Dual-energy x-ray absorptiometry technique was used to measure bone density, and blood samples were obtained to measure biochemical markers. To find predictive variables for bone mineral density (BMD), stepwise regression analysis was carried out. A total of 53 IBD patients (32.1%) had diminished bone mineral density at either lumbar spine (L1-L4) or femoral neck. Of these, 9 (5.4%) had osteoporosis; however, 44 (26.7%) were osteopenic. Femoral neck bone density was significantly decreased among CD patients (p

Background Hemangioma, a congenital vascular malformation, is the most common benign liver lesion that is usually remain stable subsequently requiring not treatment; however, complications such as abdominal pain or fullness, coagulation disturbances, and inflammatory syndrome may occur, demanding a specific treatment of hemangioma. Objectives To assess the safety, feasibility and efficacy of trans-catheter arterial embolization (TAE) for the treatment of Liver hemangioma. Patients and methods TAE was performed on 20 patients with liver hemangioma. The embolic agent used was polyvinyl alcohol (PVA) particles (300-400 micron, Jonson and Johnson Cordis, USA). All patients were followed up for 6 months. Imaging was carried out and patients were also evaluated symptomatically through telephone interview by a physician. Results Twenty patients aged from 21 to 63 years (mean: 46.8, SD: 10.26) were included in this study. Post embolization syndrome, including abdominal pain, fever, and leukocytosis occurred in one patient 1 week after TAE and lasted for 3 days. No serious adverse event and TAE-related death was observed. None of the patient underwent another intervention including surgery. During follow up interval, decreased episode of abdominal pain was documented in all patients who had pain. Tumor enlargement was also stopped during the follow up. The average diameter of tumors was 97.00 mm (range: 25-200 SD: 47.85) and 88.95 mm (range: 23-195 SD: 43.27) before and after embolization, respectively. Comparison of images before and after TAE revealed statistically significant decrease in the size of lesion (P value: 0.004, t: 3.31). Conclusions Our findings indicate that TAE is a safe and efficient procedure for the treatment of liver hemangioma. Further studies with larger sample sizes are required to support therapeutic effects of TAE.

Adenosine deaminase activity is proposed as a marker of inflammation in some inflammatory conditions. To investigate the association of serum adenosine deaminase activity and disease activity in Crohn’s disease patients. In a cross-sectional study, 30 consecutive known cases of Crohn’s disease (15 with active disease and 15 in remission) referring to a university hospital in Tehran (Iran) and 15 age- and gender-matched healthy controls were studied. Disease activity was assessed using the Crohn’s disease activity index (cutoff >150). Total serum adenosine deaminase activity, C-reactive protein, erythrocyte sedimentation rate, and fecal calprotectin were evaluated in patients. Serum adenosine deaminase activity was measured in controls. Mean age of the patients was 36.8 ± 12.6 years, and 56.7 % were male. Serum adenosine deaminase activity in patients with active disease, patients in remission, and controls was 12.3 ± 5.9, 14.6 ± 6.2, and 11.9 ± 6.4 U/L, respectively (P = 0.458). Compared with patients in remission, those with active disease had higher erythrocyte sedimentation rate (40.4 ± 30.6 vs. 16.9 ± 16.0 mm/h, P = 0.014) and higher frequency of positive C-reactive protein (66.6 vs. 13.3 %, P = 0.004) and positive fecal calprotectin tests (86.6 vs. 33.3 %, P = 0.004). Serum adenosine deaminase activity was not correlated with erythrocyte sedimentation rate (r = 0.05, P = 0.761) and was not different between patients with positive and negative C-reactive protein (12.2 ± 5.4 vs. 14.2 ± 6.5 U/L, P = 0.393) and fecal calprotectin tests (11.7 ± 5.3 vs. 16.0 ± 6.5 U/L, P = 0.063). In patients with Crohn’s disease, serum adenosine deaminase activity is not associated with clinical disease activity or with other inflammation markers and cannot be suggested as an inflammation marker.

Previous studies have suggested some benefits of nonsteroidal antiinflammatory drugs (NSAIDs) use in patients with chronic viral hepatitis. We evaluated potential effects of indomethacin in asymptomatic carriers of hepatitis B surface antigen (HBsAg).Randomized, placebo-controlled, double-masked clinical trial.One hundred and twelve patients who were confirmed to be HBsAg carriers for at least 6 months and had normal liver function tests, normal abdominal sonography, and no sign of cirrhosis were randomly assigned into two groups. One group (56 participants, mean age (+/-SD) 31.7 (+/-9.6) yr, 29 male, mean serum alanine aminotransferase (ALT) (+/-SD) 24.9 (+/-9.2)) received indomethacin capsules (25 mg) three times daily and the other group (56 participants, mean age (+/-SD) 33.8 (+/-10.2) yr, 33 male, mean serum ALT (+/-SD) 24.5 (+/-8.7)) took placebo capsules with identical package and appearance. All participants were under treatment for 6 months and were followed 3 months thereafter. Statistical analyses were performed both by intention-to-treat and on-treatment methods.Nine participants in the indomethacin group (16%) and 8 in the placebo group (14%) did not complete the trial. HBsAg seroconversion did not differ by treatment group (2 subjects in each group became seronegative). Hepatitis B virus DNA (HBV-DNA) became negative in sera of 7 participants in the indomethacin group but only in 1 in the placebo group (intention-to-treat p= 0.06; on-treatment p= 0.03). Seroconversion of HBeAg to anti-HBe occurred only in 5 participants in the indomethacin group (intention-to-treat p= 0.06; on-treatment p= 0.03). Adverse events included one case of hepatotoxicity and two cases of gastritis in the indomethacin group and one suspected gastritis in the placebo group.We suggest use of indomethacin only in the subgroup of asymptomatic HBsAg carriers who have detectable HBV-DNA or HBeAg in their sera.

Interleukin (IL)-1 family members play an important role in the pathogenesis of inflammatory bowel disease (IBD). There are conflicting results regarding the association of IL-1 gene cluster single nucleotide polymorphisms (SNPs) with IBD and its clinical features. The aim of this study was to examine IL-1α −889 C/T, IL-1β −511 C/T, IL-1β +3962 C/T, IL-1R Pst-I1970 C/T, and IL-1RA Mspa-I11100 C/T SNPs in Iranian patients. In this study, SNPs of IL-1 family members were investigated in 75 patients with IBD (40 CD and 35 UC), using polymerase chain reaction with sequence-specific primers method. IL-1β −511 CC genotype was significantly less present in UC compared to controls, while IL-1RA Mspa-I11100 CC was significantly associated with both Crohn’s disease (CD) and ulcerative colitis (UC). IL-1α −889 TT genotype was more frequently associated with extraintestinal manifestations. A significant association was observed between IL-1β +3962 TT genotype and the disease activity in IBD. IL-1RA Mspa-I11100 CC was significantly less frequent in CD patients who need immunosuppressive therapy. IL-1RA Mspa-I11100 CT was associated with earlier age of onset in IBD, while TT genotype was associated with higher age of onset in IBD. IL-1 SNPs seem to be associated with IBD and could affect the disease severity as well.

Background: Current guidelines introduce periodic monitoring of serum alanine transaminase (ALT) as the first-line modality in follow-up patients, with a hepatitis B virus (HBV) inactive carrier state. Objectives: This study aimed to determine the incidence rate and patterns of ALT fluctuations and prognostic values for the development of chronic HBV e antigen (HBeAg)-negative hepatitis B (CHB), HBV surface antigen (HBsAg) seroclearance, and liver-related complications. Patients and Methods: Treatment-naïve patients with a chronic HBV infection, HBeAg(-)/HBeAb(+), normal ALT levels, and HBV DNA < 2000 IU/mL, were followed-up every 6-12 months by assessing serum ALT levels. Serum HBV DNA was measured in cases of elevated ALT levels. Results: A total of 399 patients were followed-up for 8.9 years; ALT > upper limit of normal (ULN, i.e. 40 IU/L) was detected in 103 (25.8%) patients, with an annual incidence rate of 2.9%. ALT elevation was associated with; male gender, age, and higher serum ALT levels at study entry. Among the cases of ALT elevations, 16 (15.5%) patients had ALT levels > 2 × ULN. There were 38 (36.9%) patients who had ALT levels that remained > ULN over six months, and 21 (20.4%) patients experienced at least two episodes of ALT elevations. In 15 (14.6%) patients, elevated ALT levels were associated with increased HBV replication (i.e. HBV DNA > 2 000 IU/mL) and these were considered as CHB. However, elevation of ALT levels, even in the absence of HBV replication, increased the risk for the development of CHB up to 8-fold in prospective follow-ups. HBsAg seroclearance, cirrhosis, and hepatocellular carcinoma were detected in 43 (10.8%), 4 (1%), and 1 (0.25%) patients, respectively. Conclusions: Fluctuations in serum ALT levels may change the prognosis of a HBV inactive carrier state.

The cross-border symposium on hepatitis C, entitled “why treating now?” was held on 15th May 2013 during the 5th International Tehran Hepatitis Congress. The present report summarizing communicated insights during this symposium is intended to help health care providers to make well-informed decisions when treating patients with chronic hepatitis C (CHC). Since today’s evolving science of hepatitis C management has introduced new treatment options, one should be well-versed about the potential benefits as well as untoward effects or practical challenges when using these regimens. In addition to outline HCV treatment advances, this symposium focused on the central question that why eligible patients with hepatitis C who may mostly benefit from the currently available protease inhibitors, should be treated now rather than be waited for the future therapies. Moreover, an overview of long term local experience with protease inhibitors in our challenging hepatitis C patients was presented during this interactive symposium.
