Objectives: This study aims to evaluate the sensitivity and specificity of salivary anti-cyclic citrullinated peptide 3 (anti-CCP3) for the early diagnosis of rheumatoid arthritis. Patients and methods: Between June 2017 and April 2019, a total of 63 patients with rheumatoid arthritis (10 males, 53 females; mean age: 50.4±9.5 years; range, 27 to 74 years) and 49 healthy controls (8 males, 41 females; mean age: 49.3±9.3 years; range 27 to 67 years) were included. Salivary samples were collected by passive drooling. Anti-cyclic citrullinated peptide analyses of salivary and serum samples were performed. Results: The mean polyclonal immunoglobulin (Ig)G-IgA anti-CCP3 salivary levels were significantly different in patients (149.2±134.2) compared to healthy controls (28.5±23.9). The mean polyclonal IgG-IgA anti-CCP3 serum levels were measured as 254.0±169.5 in patients and 3.8±3.6 in healthy individuals. The diagnostic accuracy analysis of salivary IgG-IgA anti-CCP3 results in an area under the curve (AUC) of 0.818, as well as 91.84% specificity and 61.90% sensitivity. Conclusion: Salivary anti-CCP3 may be considered as an additional screening test for rheumatoid arthritis. [ABSTRACT FROM AUTHOR]

Background: Considering the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic, which causes coronavirus disease 2019 (COVID-19), we aimed to report the clinical features of 427 patients with COVID-19 and the outcomes after one-month admission to major teaching hospitals in the northeast of Iran. Materials and Methods: Data of patients hospitalized with COVID-19 from 20 February 2020 to 20 April 2020 was analyzed using the R software. The cases and their outcomes were monitored up to one month following their admission. Results: Among 427 patients with a median age of 53 years (50.8% male), 81 (19%) were directly admitted to the ICU ward, and 68 (16%) died during the study. The mean (SD) lengths of hospital stay were significantly higher in the non-survivors (6 (9) days) than survivors (4 (5) days) (P = 0.018). Ventilation need was reported in 67.6% of the non-survivors and 0.8% of the survivors (P < 0.001). Cough (72.8%), fever (69.3%), and dyspnea (64.0%) were the most common symptoms. There were more comorbidities in the severe cases (73.5%) and non-survivor (77.5%). Liver and kidney damage were significantly more common in non-survivors. Ninety percent of the patients had at least one abnormal chest CT scan finding, including crazy paving and consolidation patterns (27.1%), followed by the ground-glass opacity (24.7%). Conclusion: Results showed that the patients’ age, underlying comorbidities, levels of SpO2, and laboratory findings at the time of admission may predict the progress of the disease and can be considered mortality-related factors.

Background: Genetic variations of aryl hydrocarbon receptor (AHR) pathway genes could influence the imbalanced immune response to xenobiotics. Therefore, we aimed to investigate the polymorphism of AHR pathway genes in systemic lupus erythematosus (SLE) patients in association with smoking. Methods: Genomic DNA from patients (N = 107) and controls (N = 105) of a population from northeast of Iran was used for genotyping of CYP1A1 T>C (rs4646903) and AHRR C>G (rs2292596) variants. The SLEDAI score and smoking status of the patients were registered. The AHR activity was estimated by CYP1A1 and CYP1B1 gene expression in peripheral blood mononuclear cells (PBMC). Results: The C allele in rs4646903 (odds ratio [OR] = 2.67) and G allele in rs2292596 (OR = 1.79) SNPs were significantly associated with the increased risk of SLE. The AHR pathway was more active in high‐risk CYP1A1/AHRR: C/G haplotype. The most severe disease was observed in smoker patients with high‐risk haplotype and both smoking (Exp (β) = 9.5) and high‐risk CYP1A1/AHRR (C/G) haplotype (Exp (β) = 3.7) can significantly increase the likelihood of having severe (SLEDAI ≥ 20) SLE disease activity. Conclusion: Our findings indicated the association of xenobiotic‐metabolizing genes (CYP1A1, AHRR) polymorphisms with the susceptibility to SLE and disease severity regarding the smoking background, suggesting the interaction of gene and environmental risk factors in SLE pathogenesis.

Herein, we evaluated the adsorption of thiazole over the surface of BC2N nanotube using PBE and M06-2X functionals and 6-311G** standard basis set. We considered one and two thiazole molecules over the outer sidewall of BC2N nanotube. Furthermore, we found that the adsorption energy of thiazole (state II) from its nitrogen head on the boron atom of BC2N nanotube is greater than other states (about − 0.90 eV by PBE and − 1.09 eV by M06-2X functional). It was found that the energy gap of BC2N nanotube is significantly reduced from 0.61 to 0.25 eV after the thiazole adsorption (state II). Our results also indicated that the electronic and optical properties of BC2N nanotube are significantly altered on the adsorption of thiazole. [ABSTRACT FROM AUTHOR]

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with unknown aetiology. According to the role of interleukin 10 (IL10) in SLE pathogenesis, the genetic alterations in its promoter region could be associated with elevated IL10 levels and exacerbated disease. Here, we investigated the association of genotype and haplotype frequencies of three IL10 gene promoter polymorphisms with susceptibility to SLE, IL10 plasma levels and disease activity of patients in an Iranian population. A total of 116 SLE patients and 131 healthy subjects were enrolled. The PCR‐RFLP technique was used to detect IL10 promoter genotypes at the positions of −1082 (G/A), −819 (C/T) and −592 (C/A) in association with IL10 plasma levels and SLEDAI scores. The GG genotype of −1082 polymorphism was associated with the increased risk of SLE [OR = 2.65, 95% CI (1.21–5.82), p‐value = 0.046]. The CC genotype in −819 region was associated with SLE susceptibility [OR = 3.38, 95% CI (1.26–9.07), p‐value = 0.034] and C allele was introduced as risk allele [OR = 1.86, 95% CI (1.15–3.01), p‐value = 0.009] in this region. IL10 plasma levels were overexpressed in CC genotype carriers of −592 SNP and decreased in AA genotype carriers of −1082. IL10 was also increased in SLE patients with CGT (−592/−1082/−819) haplotype. The SLEDAI score was higher among CC genotype carriers at the position of −592 and TT genotype carriers at the region of −819. SLEDAI was also elevated among patients with CGC (−592/−1082/−819) and CAC (p = 0.011) haplotypes. The present study suggests that the IL10 –819(C/T), −1082(G/A) and −592(C/A) polymorphisms and the haplotypes are associated with SLE susceptibility, increased disease activity and elevated IL10 levels. While this is the first time to report such an association in an Iranian population, further studies are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

- Abstract
A 32-year-old pregnant woman, diagnosed with Behçet’s disease 6 months earlier, presented with recent mild hemoptysis and exertional dyspnea. Transthoracic echocardiography showed an enlarged dysfunctional right ventricle. A large hypoechoic triangular-shaped mass was seen attached to the inner right ventricular wall, filling the cavity. No change in the size of the mass was noted after anticoagulant administration, and right heart failure progressed. Surgery was performed to remove the mass and repair the tricuspid valve. This was a very rare presentation of Behçet’s disease in pregnancy, which resulted in delivery of a completely healthy baby despite corticosteroid pulse therapy and cyclophosphamide.

BACKGROUND Disturbances in lipid metabolism which occur during hypothyroidism lead to the formation of gallstones. This study aims to evaluate the thyroid function pattern in patients with common bile duct (CBD) stones. METHODS This case-control study recruited 151 patients with preliminary diagnoses of CBD stone who underwent ERCP (cases). The control group comprised healthy people who met the study criteria in the same hospital. The control group underwent ultrasonography to exclude any asymptomatic bile duct lithiasis. A questionnaire that included demographic and anthropometrics data were completed by an assigned physician. Morning blood samples that followed 12 hours of fasting were taken from all participants for measurements of serum total thyroxin (T4), serum thyroid stimulating hormone (TSH), fasting blood sugar (FBS), triglycerides (TG), total cholesterol, low density lipoprotein (LDL) and high density lipoprotein (HDL). RESULTS The mean TSH in patients (2.59 ± 4.86mg/dl) was higher than the control group (2.53± 4.13 9mg/dl). In subclinical hypothyroidism, serum TSH levels higher than 5 MU/L were found in 30.6% of cases compared with 22.5% of controls [OR: 1.53; 95 % confidence interval (95% CI): 0.968-2.438). Hypothyroidism was detected in 10.8% of the control group and in 11.3% of cases (OR: 1.87; 95% CI: 0.578-2.043). The mean total cholesterol levels in cases was higher than the control group (p=0.61).The levels of TG (p=0.05), HDL (73.35 vs. 46.41; p<0.01) and LDL (64.81.88 vs. 111.04; p<0.01) was statistically significant between both groups. CONCLUSION There is an association between thyroid disorders and the presence of bile duct stones. Thyroid testing in patients with gallstone and bile duct stones is recommended because hypothyroidism may be a predisposing factor for stone passage from the gallbladder. [ABSTRACT FROM AUTHOR]

Background and Objective: Systemic lupus erythatous (SLE) is an autoimmune disease with clinical symptoms. Anti neutrophil cytoplasmic antibody (ANCA) is common in vasculitis which is reported in SLE. This study was done to determine the frequency of ANCA in patient with SLE and its association with disease activity. Methods: This descriotive study was conducted on 80 patients with SLE whom referred to rheumatology clinic in Gorgan, northern Iran during 2012-15. The patients disorder diagnosed based on the ACR Criteria. According to the disease activity the patients divided to active group and inactive group. Demographic data was completed with questionnaire and blood sample collected in order to evaluate of for serum ANCA by using ELISA method. Results: The average age was 37.5±12.4 year. Seven (8.5%) patients were males. 91.5% of patients was females. 27 patients (33%) had active lupus and 53 (57%) had inactive lupus. Only one patient has been reported as positive for ANCA. The patient was a 45 years woman with history of 10 years of lupus nephritis with active disease. Conclusion: There was no relationship between ANCA and disease activity. The main reason for this finding can be a few numbers of positive cases in this study. [ABSTRACT FROM AUTHOR]

Background: Recent evidence suggests overall diet quality, as assessed by dietary scores, may play a role in the development of upper gastrointestinal (UGI) cancers. However, the existing dietary scores are derived from high-income countries with different dietary habits than regions with the highest burden of UGI cancers, where limited data is available. This study aimed to investigate the association between overall diet quality and risk of esophageal and stomach cancers in a high-risk region for UGI cancers. Methods: We recruited 50 045 individuals aged 40-75 between 2004-2008 from northeastern Iran and followed them annually through July 2020. Data on demographics, diet, and various exposures were collected using validated questionnaires. Diet quality was assessed by calculating the Healthy Eating Index (HEI), Alternative Healthy Eating Index (AHEI), Alternative Mediterranean Diet (AMED), Dietary Approaches to Stop Hypertension (DASH), and World Cancer Research Fund--American Institute for Cancer Research (WCRF-AICR) scores. Results: During an average 12 years of follow-up, 359 participants developed esophageal cancer and 358 developed stomach cancer. After adjustments, each standard deviation increase in baseline dietary scores was associated with up to 12% reduction in esophageal cancer risk and up to 17% reduction in stomach cancer risk. Esophageal cancer showed stronger inverse associations with adherence to AMED (HRQ4-vs-Q1 = 0.69 (0.49-0.98), P-trend = 0.038). Stomach cancer showed stronger inverse correlation with WCRF-AICR (HRQ4-vs-Q1 = 0.58 (0.41-0.83), P-trend = 0.004), and DASH (HRC4-vs-C1 = 0.72 (0.54-0.96), P-trend = 0.041). These associations were comparable across different population subgroups. We did not observe significant associations between HEI and AHEI scores and UGI cancers in this population. Conclusion: Despite the differences in consuming individual food groups, adherence to the available dietary recommendations (derived from high-income countries) was associated with lower risk for subsequent esophageal and gastric cancers in this high-risk population. Educating the public to have a healthy eating pattern might be an effective strategy towards prevention of UGI cancers in high-risk regions. [ABSTRACT FROM AUTHOR]

Background: This study was conducted to evaluate the epidemiological features of bone and soft cancers in the Golestan province, Northern Iran from 2004 to 2016. Methods: This is a descriptive cross-sectional study. All patients with primary bone and soft tissue cancers between 2004 and 2016 were included. Data were obtained from Golestan population-based cancer registry (GPCR). We calculated age-standardized incidence rates (ASRs) and reported the rates per 100 000 person-year. Estimated annual percent change (EAPC) was also calculated to assess temporal trends in incidence rates of these cancers. Results: The ASRs of bone cancers and soft tissue cancers were 1.33 and 1.43 per 100 000 person-year, respectively. This study also showed that the ASR of bone cancer was higher in men (1.51) than women (1.15). The ASR of soft tissue cancers in the urban population (1.58) was higher than rural (1.27), and was lower in women (1.37) than men (1.49). Two peaks were seen in the incidence of bone cancer. The first peak was in the age group of 10 to 20 years and the second was in patients over 60. We did not find significant temporal trends in the incidence of bone (EAPC = -1.14; P > 0.05) and soft tissue cancers (EAPC = -2.73; P > 0.05) during the study period. Conclusion: Epidemiological features of bone and soft tissue cancers including gender, age and place of residence should be considered by health policy makers in designing cancer control programs.

Recently, due to the coronavirus disease 2019 (COVID-19) pandemic, much concern has been raised about patients with chronic diseases who may become more susceptible to the disease. The present cross-sectional study aimed to characterize the clinical course of COVID-19 in patients with systemic lupus erythematosus (SLE). In addition, a possible correlation between the immunosuppression state and the incidence of COVID-19 is investigated. In May 2020, 500 SLE patients registered in the database of Golestan Rheumatology Research Center (Golestan province, Iran) were selected for this cross-sectional study. Using a questionnaire, patients were contacted by telephone to collect data including demographic characteristics, disease status, drug use, and new clinical symptoms. Data were analyzed using SPSS software version 24.0. Of the 500 selected patients, 355 responded to the phone calls and subsequently enrolled in the study. Among the enrolled patients, 25 were classified as COVID-19 positive, including eight hospitalized patients, of which two required intensive care and subsequently died. COVID-19 incidence was significantly lower in the immunosuppressed patients (2.2% vs. 10%, P=0.01). There was no significant correlation between hydroxychloroquine consumption and the incidence of COVID- 19 in SLE patients. Fever, fatigue, dyspnea, and dry cough were the most common clinical symptoms. Our results showed that COVID-19 incidence was lower in immunosuppressed than the non-immunosuppressed SLE patients. Further studies are required to substantiate the role of immunosuppression in the development of COVID-19. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder impacting multiple organs, influenced by genetic factors, especially those related to the immune system. However, there is a need for new biomarkers in SLE. MicroRNA-125a (miR-125a) levels are decreased in T cells, B cells, and dendritic cells of SLE patients. MiR-125a plays a regulatory role in controlling the levels of tumor necrosis factor-alpha (TNF-α) and interleukin 12 (IL-12), which are crucial pro-inflammatory cytokines in SLE pathogenesis., Aim: To assess the levels of miR-125a, IL-12, and TNF-α in SLE patients' plasma, evaluating their diagnostic and prognostic value., Methods: The study included 100 healthy individuals, 50 newly diagnosed (ND), and 50 SLE patients undergoing treatment. The patients were monitored for a duration of 24 wk to observe and record instances of relapses. MiR-125a expression was measured using real-time reverse transcription polymerase chain reaction, while ELISA kits were used to assess IL-12 and TNF-α production., Results: The results showed significantly reduced miR-125a expression in SLE patients compared to healthy individuals, with the lowest levels in ND patients. TNF-α and IL-12 expression levels were significantly elevated in SLE patients, especially in the early stages of the disease. Receiver operating characteristic curve analyses, and Cox-Mantel Log-rank tests indicated miR-125a, TNF-α, and IL-12 as proper diagnostic biomarkers for SLE. A negative correlation was found between plasma miR-125a expression and IL-12/TNF-α levels in SLE patients., Conclusion: Decreased miR-125a levels may be involved in the development of SLE, while elevated levels of IL-12 and TNF-α contribute to immune dysregulation. These findings offer new diagnostic and prognostic markers for SLE. Moreover, the negative correlation observed suggests an interaction between miR-125a, TNF-α, and IL-12. Further research is necessary to uncover the underlying mechanisms that govern these relationships., Competing Interests: Conflict-of-interest statement: All the authors declare that there are no conflicts of interest to disclose., (©The Author(s) 2023.

- Abstract
Background: Systemic sclerosis is an autoimmune disease characterised by endothelial dysfunction and fibrosis of the skin and internal organs. Cardiac involvement during systemic sclerosis can be primary or secondary to pulmonary arterial hypertension and renal pathology. Among the disorders in systemic sclerosis, prolongation of QTc time is also associated with more anti-RNA polymerase III antibodies, longer duration, and severity of disease., Methods: This case-control study was performed on 35 patients with systemic scleroderma who filled in the American Society of Rheumatism (ACR / EULAR criteria) and 35 healthy subjects prior to entering the study. Then, the QTc distance was extracted from the electrocardiogram and calculated using the formula. The measured QTc distance in the electrocardiogram, QTc> 440ms in men and QTc> 460ms in women, was defined as QTc long. The patients and the control group then underwent echocardiography, and changes in QTc interval and their relations with echocardiographic findings were evaluated., Results: The results of this study indicated a significant relationship between QTc distance in patients with scleroderma compared with healthy controls. There was also a significant relationship between QTc and Skin Score of patients. However, there was no significant correlation between QTc distance and age, duration of disease, Anti-Centromere, Anti-Scl70, and pulmonary artery pressure., Conclusion: This study concludes that patients with scleroderma are at high risk for cardiac conduction impairment. The only factor that significantly correlated with QTc was the Skin Score of the patients., Competing Interests: We declare no competing interests., (© 2023 The Mediterranean Journal of Rheumatology (MJR).)

- Abstract
Objectives: This study aims to evaluate the sensitivity and specificity of salivary anti-cyclic citrullinated peptide 3 (anti-CCP3) for the early diagnosis of rheumatoid arthritis., Patients and Methods: Between June 2017 and April 2019, a total of 63 patients with rheumatoid arthritis (10 males, 53 females; mean age: 50.4±9.5 years; range, 27 to 74 years) and 49 healthy controls (8 males, 41 females; mean age: 49.3±9.3 years; range 27 to 67 years) were included. Salivary samples were collected by passive drooling. Anti-cyclic citrullinated peptide analyses of salivary and serum samples were performed., Results: The mean polyclonal immunoglobulin (Ig)G-IgA anti-CCP3 salivary levels were significantly different in patients (149.2±134.2) compared to healthy controls (28.5±23.9). The mean polyclonal IgG-IgA anti-CCP3 serum levels were measured as 254.0±169.5 in patients and 3.8±3.6 in healthy individuals. The diagnostic accuracy analysis of salivary IgG-IgA anti-CCP3 results in an area under the curve (AUC) of 0.818, as well as 91.84% specificity and 61.90% sensitivity., Conclusion: Salivary anti-CCP3 may be considered as an additional screening test for rheumatoid arthritis., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2023, Turkish League Against Rheumatism.)

- Abstract
Systemic sclerosis (SSc) is a chronic autoimmune disease , featuring fibrosis in multiple organs. The serum from SSc patients contain inflammatory mediators, contributing to SSc pathogenesis and could be used to develop cell culture models. Here, we compared the fibrotic effects of serum samples from SSc patients with TGFβ1 on human dermal fibroblasts (HDFs). HDF cells were cultured in four different culture media supplementations; 10% SSc serum, 10% healthy human serum, 10% fetal bovine serum or 10% FBS supplemented with 10 ng/Ml human TGFβ. The collagen content in cell layers was measured by spectrophotometric Picro-Sirius red staining. The mRNA expression of α-SMA , COL I and III , TGFβ1 , arginase and E-Cadherin genes were determined by real time RT-PCR. TGF-β1 levels in cell culture supernatants were measured using ELISA. Cell layer collagen content was significantly increased following TGF-β1 treatment, compared with FBS group and SSc serum treatment in comparison with healthy controls. Although not statistically significant, the mRNA expression of α-SMA, COLI and III , TGFβ1 , and arginase increased upon TGF-β1 treatment in comparison with FBS group, and in SSc serum treatment group in comparison with healthy controls. E-Cadherin decreased following TGF-β1 treatment and SSc serum treatment in comparison with their counterparts. TGF-β1 levels increased in cell culture supernatants of HDF cells exposed to TGF-β1 and SSc serum. An in vitro model of SSc serum-induced fibrosis using human HDF cells was evaluated in comparison to the TGF-β1 fibrosis induced model and data suggested that it may be used in documenting the role of pro-fibrotic factors in serum or plasma from SSc patients., Competing Interests: Authors declare no conflict of interest.

- Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with unknown aetiology. According to the role of interleukin 10 (IL10) in SLE pathogenesis, the genetic alterations in its promoter region could be associated with elevated IL10 levels and exacerbated disease. Here, we investigated the association of genotype and haplotype frequencies of three IL10 gene promoter polymorphisms with susceptibility to SLE, IL10 plasma levels and disease activity of patients in an Iranian population. A total of 116 SLE patients and 131 healthy subjects were enrolled. The PCR-RFLP technique was used to detect IL10 promoter genotypes at the positions of -1082 (G/A), -819 (C/T) and -592 (C/A) in association with IL10 plasma levels and SLEDAI scores. The GG genotype of -1082 polymorphism was associated with the increased risk of SLE [OR = 2.65, 95% CI (1.21-5.82), p-value = 0.046]. The CC genotype in -819 region was associated with SLE susceptibility [OR = 3.38, 95% CI (1.26-9.07), p-value = 0.034] and C allele was introduced as risk allele [OR = 1.86, 95% CI (1.15-3.01), p-value = 0.009] in this region. IL10 plasma levels were overexpressed in CC genotype carriers of -592 SNP and decreased in AA genotype carriers of -1082. IL10 was also increased in SLE patients with CGT (-592/-1082/-819) haplotype. The SLEDAI score was higher among CC genotype carriers at the position of -592 and TT genotype carriers at the region of -819. SLEDAI was also elevated among patients with CGC (-592/-1082/-819) and CAC (p = 0.011) haplotypes. The present study suggests that the IL10 -819(C/T), -1082(G/A) and -592(C/A) polymorphisms and the haplotypes are associated with SLE susceptibility, increased disease activity and elevated IL10 levels. While this is the first time to report such an association in an Iranian population, further studies are needed to confirm these findings., (© 2018 John Wiley & Sons Ltd.)

- Abstract
Background and Aim: Lymphoid cell infiltration and destruction of exocrine glands, specifically lacrimal and salivary glands are characteristics of Sjogren's syndrome (SS). An etiological role has been proposed for Helicobacter pylori (H. pylori), interacting in the clinical course and complications of SS (including gastric cancer and lymphoma). The aim of this study was to identify the probable correlation between H. pylori infection and Sjogren's syndrome (SS)., Methods: In this case-control study, ELISA method was used to determine serum level of IgA and IgM anti H. pylori antibody in 43 subjects with SS according to the international criteria and 95 healthy subjects as control. SPSS-17 was used to analyze data with t-test. P value <0.05 were considered significant., Results: Serum level of IgM (34.9% vs. 10.5%, p-value= 0.001) and IgA (67.4% vs. 46.3% p value= 0.021) anti H. pylori antibody were significantly higher in SS patients compared to the control group. There was a positive correlation between age and H. pylori infection (r=0.2, Pvalue= 0.05)., Conclusion: Patients with SS had a higher prevalence of H. pylori infection compared to the normal population. Eradication of H. pylori is recommended particularly in older patients with SS., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Background and Purpose: Hepatitis D virus (HDV) is a defective RNA virus dependent on hepatitis B virus (HBV) infection for its replication and expression. It is known that coexistent infection with HDV tends to aggravate the course of HBV-associated liver disease. This study was carried out to determine the seroprevalence of HDV among hepatitis B surface antigen (HBsAg)-positive individuals in the northeast part of Iran., Methods: 139 HBsAg-positive subjects detected from a population-based single stage cluster sampling in Golestan province of Iran were enrolled. All cases were evaluated for the presence of anti-HDV antibodies using commercially available enzyme-linked immunoabsorbent assay kits. Logistic regression was used to determine the relationship between independent variables and HDV seropositivity., Results: Of 139 cases, 68 were males (48.9%) and 71 were females (51.1%). The mean age was 41.9 +/- 11.3 years (range, 25-64 years). Anti-HDV antibody was positive in 8 subjects (5.8%), with a female predominance (9.9% vs 1.5%, p=0.06; odds ratio, 7.32; 95% confidence interval, 0.87-61.23). No significant relationship was seen between anti-HDV seropositivity and demographic factors such as age, place of residence and marital status., Conclusions: These findings show that HDV infection is endemic in Golestan province (northeast) of Iran. Seroprevalence of anti-HDV in the present study was higher than in some previous studies from other parts of Iran. Our results suggest that the prevalence of HBV/HDV coinfection in Golestan province of Iran has increased during the last decade. Therefore, practitioners and health care managers should be made aware of the risk of dual infection with HBV and HDV.

- Abstract
This study was carried out to determine the seroprevalence of hepatitis D virus among HBsAg positive individuals in the northeast part of Iran. One hundred thirty nine HBsAg positive subjects detected from a population based single stage cluster sampling in Golestan province of Iran were enrolled. All cases were evaluated for the presence of anti-HDV antibodies using commercially available ELISA kits. Logistic regression was used to determine the relationship between independent variables and HDV seropositivity. Of 139 cases, 68 (48.9%) were males and 71 (51.1%) were females. The mean age was 41.89 +/- 11.30 years (25-64 years). Anti-HDV antibody was positive in 8 (5.8%) subjects with female predominance (9.9% versus 1.5%, p = 0.06; odds ratio = 7.32, 95% CI: 0.87-61.23). No significant relationship was seen between anti-HDV seropositivity and demographic factors such as age, place of residence and marital status. These findings showed that HDV infection was endemic in Golestan province (northeast) of Iran. Seroprevalence of Anti-HDV in the present study was higher than some previous studies from other parts of Iran. Our results suggest that the prevalence of HBV/HDV co-infection in Iran has increased during the last decade. Therefore, practitioners and all health care managers should be made aware of the risk of dual infection with HBV and HDV.

- Abstract
Background/aims: As hepatitis B and C virus have the same transmission routes, dual infection may occur. The aim of this study was to determine the seroprevalence of HCV in HBsAg-positive subjects., Methods: 139 HBsAg-positive subjects were enrolled in the study. Serum samples were tested using ELISA method for anti-HCV antibodies. Chi-square and Fisher's exact tests were used to compare the proportions., Results: There were 68 (48.9%) males and 71 (51.1%) females. The mean age was 41.89+/-11.30 years. One case was excluded because of inadequate blood sampling. Anti-HCV antibody was positive in 17 (12.3%) of the 138 remaining subjects. Seropositivity of HCV was similar between female and male patients (p=0.69)., Conclusion: The seroprevalence of co-infection with hepatitis B virus and hepatitis C virus in our study was higher than such reports from some countries (Italy), but was in line with worldwide prevalence (>10%).

- Abstract
Background/aims: Although a "hospital-based cancer registry" is important in improving patient care, a "population-based cancer registry" with emphasis on epidemiology is important in allocating health care resources and prioritizing public health programs. Because of its reliance on retrieved clinical and para-clinical documents, there is some limitation in registering all cancer incidents in this system, especially in developing countries. In this study we examined the possibility of using public data as a complementary source of information for recording cancers in a population-based cancer registry., Methods: Along with the annual census in rural areas, a survey was performed in Golestan province in March 2004 to identify public awareness about cancer incidents in the community. Individuals were questioned about history of cancer in their close relatives during the last two years. Those who reported cancer in their relatives were also asked to name the main organ of involvement. A similar list was retrieved from the cancer registry at the Ministry of Health in Gorgan, and cases with upper GI (esophagus and gastric) cancer diagnosis from 21 March 2002 through 20 March 2004 were selected for this study. Finally, these two lists were compared for examining accuracy of the collected data., Results: We included 137 cases in our study with rural residence and known addresses. Only 35 (25.5%) cases were reported by the relatives and among them only 20 (57.1%) relatives correctly reported the tumor location. Although we found a difference in accurate reporting of cancer incidents by year of diagnosis (more correct cases reported during the second versus the first year), the difference was not statistically significant between the two years., Conclusion: In this study, we examined the possibility of using public awareness about cancer incidents as a complementary source of information for a population-based cancer registry. We found that this approach is not ideal for reducing limitations. Therefore, we recommend a nationwide cancer registry to record all cancer-related information at the time of diagnosis. This strategy will reduce the need for performing retrospective surveys in collecting cancer-related information.
