Identifying risk factors associated with severe SARS-CoV-2 infections is of paramount importance to protect HCWs and the non-infected patients attending different healthcare facilities.Purpose: To recognize the predictors for severity of SARS-CoV2 infection among HCWs working in either COVID-19 or non-COVID-19 healthcare settings. Also, to assess compliance of HCW to standard precautions of infection control and explore the possible risk factors for SARS-CoV-2 infection among HCWs.Methods: A cross-sectional study was conducted among HCWs with suspected or confirmed SARS-CoV-2 infection, from different Egyptian governorates. They were asked to fill in a web-based self-reporting questionnaire. The questionnaire assessed the demographic and socio-economic characteristics of participants, compliance of HCWs to standard precautions of infection control and COVID-19 presentation.Results: Our study enrolled 204 HCWs (52.3% physicians). Infection of SARS-CoV-2 was confirmed in 61.3% by RT- PCR; 35.8% were admitted to hospital, and of these, 3.9% were admitted to the intensive care unit. While 30.4% had mild disease, 48.5% had moderate disease, 17.2% had severe disease and 3.9% had critical disease. Regression analysis for variables predicting COVID-19 severity among study healthcare workers showed that associated chronic diseases and management at home were the main independent variables predicting severity of their SARS-COV-2 infection, while the variables age, sex, residence, occupation or drug history of immunosuppressives had no role in severity prediction.Conclusion: Associated chronic diseases and management at home were the main independent variables predicting severity of SARS-COV-2 infection among HCWs. So, HCWs with chronic diseases should not work in COVID-19 designated hospitals, and there should be a screening strategy for their infection with SARS-COV-2. HCWs must not be negligent in adhering to strict precautions of infection control. HCWs infected with SARS-COV-2 must be managed in hospital not at home.Keywords: health care providers, SARS-CoV-2, COVID-19, delivery of health care, infection control introduction

Identifying risk factors of severity aids in assessment for the need of early hospitalization. We aimed to demonstrate, for the first time, the clinical, laboratory and radiological characteristics of coronavirus disease 2019 (COVID-19) patients, to identify the predictors of severity and to describe the antimicrobial resistance profile in patients from Upper Egypt.Materials and Methods: Demographic characters, clinical presentations, laboratory, and radiological data were recorded and analyzed. Presence of other respiratory microorganisms and their sensitivity patterns were identified using the VITEK2 system. Resistance-associated genes were tested by PCR.Results: The study included 260 COVID-19 patients. The majority were males (55.4%) aged between 51 and 70 years. Hypertension, diabetes, and ischemic heart disease were common comorbidities. Main clinical manifestations were fever (63.8%), cough (57.7%), dyspnea (40%) and fatigue (30%). According to severity, 51.5% were moderate, 25.4% mild and 23% severe/critical. Lymphopenia, elevated CRP, ferritin, and D-dimer occurred in all patients with significantly higher value in the severe group. Age > 53 years and elevated ferritin ≥ 484 ng/mL were significant risk factors for severity. About 10.7% of the COVID-19 patients showed bacterial and/or fungal infections. Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were the predominant isolated bacteria while Candida albicans and Candida glabrata were the predominant isolated fungi. All Staphylococci were methicillin-resistant and carried the mecA gene. Gram-negative isolates were multidrug-resistant and carried different resistance-associated genes, including NDM-1, KPC, TEM, CTX-M, and SHV.Conclusion: Older age and elevated serum ferritin were significant risk factors for severe COVID-19. Bacterial co-infection and multidrug resistance among patients with COVID-19 in Upper Egypt is common. Testing for presence of other co-infecting agents should be considered, and prompt treatment should be carried out according to the antimicrobial sensitivity reports.Keywords: COVID-19, clinical characteristics, ESBL, KPC, NDM-1, risk factors, disease severity, Upper Egypt

Published papers have suggested a possible increased incidence of hepatocellular carcinoma (HCC) after successful DAAs treatment. Other papers have been published about the problem but without conclusive results. Because of this debate, we aim to evaluate the effects of antiviral therapy (Sofosbuvir plus Daclatasvir with or without Ribavirin) on the de novo occurrence of HCC in patients with liver cirrhosis (LC).Patients and Methods: A prospective cohort study has included 350 patients who have visited our center for HCV treatment. Pretreatment history, examination, complete blood picture, liver function tests, kidney function tests, HA1C for diabetic patients, HCV PCR, HBsAg, alpha-fetoprotein (AFP), and abdominal ultrasound have been done, also Child-Pogh (CP) and Model for End-Stage Liver Disease (MELD) score before treatment. These investigations have been repeated for 3 months after the end of treatment. Abdominal ultrasound (US) has been done for 3 months after treatment and every 4 months for 2 years after the end of treatment to detect HCC occurrence.Results: Patients age (58.11 ± 7.48), 55.4% of patients were males, 30.3% of patients were diabetic, 84.3% of them were treatment naïve and sustained virological response (SVR) occured in 94% of them. HCC occurrence after treatment was 6.7% in patients with SVR and 23.8% in patients with non-SVR (P value=0.016) during follow-up period. There is significant improvement of CP score. No significant changes in MELD score.Conclusion: Treatment of HCV-related LC patients with sofosbuvir and daclatasvir with or without ribavirin for 3 or 6 months showed high SVR and significant improvement in CP score, but still at risk of HCC even if treated and should be followed up regularly according to screening programs with special meticulous attention to those with non-SVR.Keywords: de-novo HCC occurrence, HCV treatment

Background and Study Aims: Currently, there is no therapy approved for COVID-19. We evaluated the efficacy and safety of sofosbuvir/ledipasvir and nitazoxanide for the treatment of patients with COVID-19 infection., Patients and Methods: A multicenter, open-label randomized controlled trial included one hundred and ninety patients with non-severe COVID-19 infection. Patients were randomized into three groups. All groups received standard care treatment (SCT). In addition, group 1 received sofosbuvir/ledipasvir, and group 2 received nitazoxanide. Follow-up by reverse-transcriptase polymerase chain reaction (RT-PCR) was done at intervals of 5, 8, 11, and 14 days. The primary endpoint was viral clearance., Results: Viral clearance was significantly higher in the sofosbuvir/ledipasvir and nitazoxanide groups compared to the SCT group in all follow-up intervals (p < 0.001). In the sofosbuvir/ledipasvir arm, 36.9% showed early viral clearance by day 5. By day 14, 83.1% of the sofosbuvir/ledipasvir group, 39.7% of the nitazoxanide group, and 19.4% of the SCT group tested negative for SARS-CoV-2. Sofosbuvir/ledipasvir and nitazoxanide treatment were the only significant factors in Cox regression of negative RT-PCR with the highest OR (17.88, 95% CI: 6.66-47.98 and 2.59, 95% CI: 1.11-6.07, respectively). No mortality or serious adverse events were recorded., Conclusion: The addition of sofosbuvir/ledipasvir or nitazoxanide to the SCT results in an early and high viral clearance rate in mild and moderate patients with COVID-19. These drugs represent a safe and affordable treatment for COVID-19., Competing Interests: Declaration of Competing Interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Pan-Arab Association of Gastroenterology.

Background and Study Aims: Contrast-enhanced ultrasonography (CEUS) has increased considerably the use of ultrasound for hemodynamical analyses and quantification. Bolus injection of microbubble agents is used to evaluate transit times. This study aimed to determine the diagnostic accuracy of arrival time (seconds) to the hepatic artery (HAAT), hepatic vein (HVAT), and portal vein (PVAT), based on CEUS used for the diagnosis of cirrhosis, and to correlate these arrival times with the liver stiffness and disease severity., Patients and Methods: This study evaluated 29 HCV cirrhotic and 19 chronic hepatitis C patients. History, clinical examination, laboratory investigations, abdominal ultrasonography, point shear-wave elastography (pSWE), and CEUS were conducted., Results: The mean liver stiffness increased significantly in cirrhotic versus chronic HCV (22.7 versus 5.1; p-value < 0.001). The mean HAAT (p-value = 0.001), PVAT (p-value = 0.002), and HVAT values (p-value: 0.001) were significantly prolonged in cirrhotic compared with chronic HCV. The HVAT cut-off point of cirrhotic patients was 18 s with a sensitivity, specificity, and accuracy of 96.6%, 63.2%, and 83.3%, respectively (area under curve: 0.801). Significant positive correlation was found between liver stiffness (kPa) and HVAT (s) (r = 0.585; p-value = 0.005). No significant correlation was detected between HVAT (s) and the severity of liver disease, as assessed by the Child or MELD scores in cirrhotic patients., Conclusion: Measuring HVAT by CEUS yielded high-accuracy and correlation outcomes for cirrhosis detection. It could be a valuable noninvasive method for the diagnosis of cirrhosis., Competing Interests: Declaration of Competing Interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Pan-Arab Association of Gastroenterology.

Background: The sickle cell trait (SCT) disorder possesses a clinical heterogeneity ranging from a symptomless condition to sudden death. This study aimed to develop a diagnostic approach that helps the characterization and identification of SCT from normal subjects and sickle cell disease (SCD) patients, and to assess its severity., Methods: Sixty controls, 24 SCD patients and 31 SCT subjects were assessed clinically, radiologically and by laboratory investigations., Results: Of the SCT subjects, 12.8% were symptomatic (3.2% anemic, 6.4% hemolytic crisis, and 3.2% painful crises). Anemia was normocytic in 66.6%, and normochromic and polychromatic in 33.4%. Significantly lower red blood cells (RBCs), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), hematocrit (Hct), Shine and Lal index (SL), and hemoglobin A (Hb A), and higher mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), Ricerca index (RI), and Huber-Herklotz index (HH) were found in SCT subjects compared with the controls. Hb A and hemoglobin S (Hb S) were excellent in discriminating SCT from SCD (cut-off for SCT > 50% and < 40%) followed by Hct, MCHC, Hb, Green and King index (GK), and England and Fraser index (EF) (cut-off for SCT > 33%, > 32, > 11, < 71, and < 10, respectively). Radiologically normal findings were detected in 87% of SCT subjects; they had nearly normal liver and renal function tests (except one case each). A schematic diagnostic paradigm for SCT was proposed., Conclusion: This study allowed understanding of SCT in various aspects, i.e., clinical, hematological, biochemical and radiological. Thus, it could help prevention of the Hb S variant disorder and proper management of carriers. This might be applied in pre-marital screening, particularly in those with family history of Hb S disorder., Competing Interests: The authors declare no conflict of interest., (Copyright 2022, Khaled et al.)

Background: The coronavirus disease 19 (COVID-19) pandemic has spread rapidly around the globe with considerable morbidity and mortality. Coexistence of comorbidities with COVID-19 had consistently been reported as risk factors for unfavorable outcome. We aimed to evaluate the impact of comorbidities in COVID-19 patients on the outcome and determine predictors of prolonged hospital stay, requisite for intensive care unit (ICU) admission. Four hundred and thirty-nine adult patients who are admitted through (June and July 2020) in our University Hospitals were included in the study. All participants were diagnosed with COVID-19 according to Egyptian Ministry of Health guidance as definite case or probable case., Results: Patients with comorbidities represented 61.7% of all cases. Constitutional symptoms especially myalgia and lower respiratory tract (LRT) symptoms such as dyspnea were significantly higher in patients with comorbidities ( P  < 0.05). Patients with comorbidities had significantly worse laboratory parameters. ICU admission was higher in patients with comorbidities (35.8%). Among different comorbidities 45.4% of cardiovascular diseases (CVD) cases were admitted in ICU followed by diabetes mellitus (DM) cases (40.8%). Also, patients with comorbidities needed invasive mechanical ventilation more than those without comorbidity (31 versus 10.7%, P  < 0.001). Significant lower frequency of recovery was found in COVID-19 patients with comorbidities (59% versus 81%, P  < 0.001) and death rate was significantly higher in cases with comorbidities ( P  < 0.001) . The survival rates in cases with pre-existing CVD and neurological diseases were lower than those without disease ( P  < 0.002 and 0.001, respectively)., Conclusions: Association of cardiovascular comorbid conditions including hypertension or neurological diseases including old cerebrovascular strokes together with COVID-19 infections carries higher risks of mortality. However, other comorbidities such as diabetes mellitus, chronic pulmonary or kidney diseases may also contribute to increased COVID-19 severity., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s) 2022.)

Backgrounds & Aim: Coronavirus disease 2019 (COVID-19) is a severe acute respiratory syndrome caused by Coronavirus. Knowledge of the fate of infection and risk factors among health care workers is essential to enforce special infection control measures. We aimed to determine the percentage of COVID-19 infection and the associated risk factors as well as the predictors of COVID- 19 among health care workers in Assiut University Hospital., Methods: A cross-sectional study was performed that included one hundred health care workers that were confirmed by PCR to be COVID-19 cases admitted to Assiut University Hospital over six months between May 2020 and November 2020. All participants were subjected to thorough history taking and full clinical examination as well as investigations., Results: Out of the 100 HCWs enrolled in the study, 52% were males, 26% were obese, 68% were doctors, and 38% were from the medical department. Fourteen percent of healthcare workers were admitted to ICU, of which 93% were cured. The predictors for severity of cases were as follows: being a doctor OR (6.804) P=0.037, old age OR (1.179) P=0.000, and hospital stay OR (0.838) P=0.015., Conclusion: Health care workers are at risk for severe COVID-19 infection. Being a doctor, old age, and duration of hospitalization were the predictors for the severity of cases of health care workers., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Researchers around the world are working at record speed to find the best ways to treat and prevent coronavirus disease 2019 (COVID-19). This study aimed to evaluate the efficacy of ivermectin for the treatment of hospitalized mild to moderate COVID-19 infected patients. This was a randomized open-label controlled study that included 164 patients with COVID-19. Patients were randomized into two groups where Group 1 (Ivermectin group) included patients who received ivermectin 12 mg once daily for 3 days with standard care and Group 2 (control group) included patients who received standard protocol of treatment alone for 14 days. The main outcomes were mortality, the length of hospital stay, and the need for mechanical ventilation. All patients were followed up for 1 month. Overall, 82 individuals were randomized to receive ivermectin plus standard of care and 82 to receive standard of care alone. Patients in the ivermectin group had a shorter length of hospital stay (8.82 ± 4.94 days) than the control group (10.97 ± 5.28 days), but this was not statistically significant (p = 0.085). Three patients (3.7%) in each group required mechanical ventilation (p = 1.00). The death rate was three patients in the ivermectin group (3.7%) versus four patients (4.9%) in the control group without any significant difference between the two groups (p = 1.00). Although there was no statistically significant difference in any endpoints by ivermectin doses (12 mg/day for 3 days); there was an observed trend to reducing hospital stay in the ivermectin-treated group., (© 2021 Wiley Periodicals LLC.)

Background: Healthcare workers (HCWs) are at a high risk for disease exposure. Given the limited availability of nucleic acid testing by PCR in low resource settings, serological assays can provide useful data on the proportion of HCWs who have recently or previously been infected. Therefore, in this study, we conducted an immunologic study to determine the seroprevalence of anti-SARS-CoV-2 antibodies in two university hospitals in Egypt., Methods: in this cross sectional study, HCWs who were working in SARS-CoV-2 Isolation Hospitals were interviewed. Estimating specific antibodies (IgM and IgG) against SARS-CoV-2 was carried out using an enzyme-linked immunosorbent assay targeting the Spike antigen of SARS-CoV-2 virus., Results: Out of 111, 82 (74%) HCWs accepted to participate with a mean age of 31.5 ± 8.5 years. Anti-SARS-COV2 antibodies were detected in 38/82 (46.3%) of cases with a mean age of 31 years and female HCWs constituted 57.6% of cases. The highest rate of seropositivity was from the nurses (60.5%), and physicians (31.6%) with only (7.9%) technicians. Only 28/82 (34.1%) HCWs reported previous history of COVID19. We reported a statistically significant difference in the timing of exposure (p = 0.010) and the frequency of contact with COVID-19 cases (p = 0.040) between previously infected and on-infected HCWs. Longer time of recovery was reported from IgG positive HCWs (p = 0.036)., Conclusion: The high frequency of seropositive HCWs in investigated hospitals is alarming, especially among asymptomatic personnel. Confirmation of diseased HCWs (among seropositive ones) are warranted., (Copyright © 2021 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

No specific treatment for COVID-19 infection is available up till now, and there is a great urge for effective treatment to reduce morbidity and mortality during this pandemic. We aimed to evaluate the effect of combining chloroquine/hydroxychloroquine (CQ/HCQ) and zinc in the treatment of COVID-19 patients. This was a randomized clinical trial conducted at three major University hospitals in Egypt. One hundred ninety-one patients with a confirmed diagnosis of COVID-19 infection were randomized into two groups: group I (96) patients received both HCQ and zinc, and group II (95) received HCQ only. The primary endpoints were the recovery within 28 days, the need for mechanical ventilation, and death. The two groups were matched for age and gender. They had no significant difference regarding any of the baseline laboratory parameters or clinical severity grading. Clinical recovery after 28 days was achieved by 79.2% in the zinc group and 77.9% in zinc-free treatment group, without any significant difference (p = 0.969). The need for mechanical ventilation and the overall mortality rates did not show any significant difference between the 2 groups either (p = 0.537 and 0.986, respectively). The age of the patient and the need for mechanical ventilation were the only risk factors associated with the patients' mortality by the univariate regression analysis (p = 0.001 and < 0.001, respectively). Zinc supplements did not enhance the clinical efficacy of HCQ. More randomized studies are needed to evaluate the value of adding zinc to other therapies for COVID 19.

Favipiravir is considered a potential treatment for COVID-19 due its efficacy against different viral infections. We aimed to explore the safety and efficacy of favipiravir in treatment of COVID-19 mild and moderate cases. It was randomized-controlled open-label interventional phase 3 clinical trial [NCT04349241]. 100 patients were recruited from 18th April till 18th May. 50 patients received favipiravir 3200 mg at day 1 followed by 600 mg twice (day 2-day 10). 50 patients received hydroxychloroquine 800 mg at day 1 followed by 200 mg twice (day 2-10) and oral oseltamivir 75 mg/12 h/day for 10 days. Patients were enrolled from Ain Shams University Hospital and Assiut University Hospital. Both arms were comparable as regards demographic characteristics and comorbidities. The average onset of SARS-CoV-2 PCR negativity was 8.1 and 8.3 days in HCQ-arm and favipiravir-arm respectively. 55.1% of those on HCQ-arm turned PCR negative at/or before 7th day from diagnosis compared to 48% in favipiravir-arm (p = 0.7). 4 patients in FVP arm developed transient transaminitis on the other hand heartburn and nausea were reported in about 20 patients in HCQ-arm. Only one patient in HCQ-arm died after developing acute myocarditis resulted in acute heart failure. Favipiravir is a safe effective alternative for hydroxychloroquine in mild or moderate COVID-19 infected patients.

Background: COVID-19 can be accompanied by acute neurological complications of both central and peripheral nervous systems (CNS and PNS). In this study, we estimate the frequency of such complications among hospital inpatients with COVID-19 in Assiut and Aswan university hospitals., Materials and Methods: We screened all patients with suspected COVID-19 admitted from 1 June to 10 August 2020 to the university hospitals of Assiut and Aswan in Upper Egypt. Clinical and laboratory tests, CT/MRI of the chest and brain, and neurophysiology study were performed for each patient if indicated., Results: 439 patients had confirmed/probable COVID-19; neurological manifestations occurred in 222. Of these, 117 had acute neurological disease and the remainder had nonspecific neuropsychiatric symptoms such as headache, vertigo, and depression. The CNS was affected in 75 patients: 55 had stroke and the others had convulsions (5), encephalitis (6), hypoxic encephalopathy (4), cord myelopathy (2), relapse of multiple sclerosis (2), and meningoencephalitis (1). The PNS was affected in 42 patients: the majority had anosmia and ageusia (31) and the others had Guillain-Barré syndrome (4), peripheral neuropathy (3), myasthenia gravis (MG, 2), or myositis (2). Fever, respiratory symptoms, and headache were the most common general symptoms. Hypertension, diabetes mellitus, and ischemic heart disease were the most common comorbidities in patients with CNS affection., Conclusion: In COVID-19, both the CNS and PNS are affected. Stroke was the most common complication for CNS, and anosmia and/or ageusia were common for PNS diseases. However, there were 6 cases of encephalitis, 2 cases of spinal cord myelopathy, 2 cases of MG, and 2 cases of myositis., (© 2021 S. Karger AG, Basel.)

Background and Study Aims: Hepatitis C virus (HCV) is a major cause of chronic hepatitis. Although liver histopathological examination remains the reference standard for liver fibrosis assessment, noninvasive means of assessment such as shear wave elastography (SWE) and aspartate aminotransferase-platelet ratio index (APRI) have been developed to reduce the need for biopsy. We evaluated the efficacy of SWE and APRI versus liver biopsy for liver fibrosis assessment in children with chronic HCV infection., Patients and Methods: Fibrosis staging was performed in 46 children (35 boys, 11 girls; mean age: 15.52 ± 2.71 years) with liver biopsy-proven chronic HCV infection according to the METAVIR system. SWE was performed within 6 months of liver biopsy. APRI scores were calculated using data collected on the day of biopsy., Results: Eighteen children had no or mild fibrosis (

Hepatitis B virus (HBV) vaccination patterns and the understanding of its risks among healthcare workers (HCWs) is a critical step to decrease transmission. However, the depth of this understanding is understudied. We distributed surveys to HCWs in 12 countries in Africa. Surveys had nine multiple-choice questions that assessed HCWs' awareness and understanding of HBV. Participants included consultants, medical trainees, nurses, students, laboratory personnel, and other hospital workers. Surveys were completed anonymously. Fisher's exact test was used for analysis, with a P -value of < 0.05 considered significant; 1,044 surveys were collected from Kenya, Egypt, Sudan, Tanzania, Ethiopia, Uganda, Malawi, Madagascar, Nigeria, Cameroon, Ghana, and Sierra Leone. Hepatitis B virus serostatus awareness, vaccination rate, and vaccination of HCWs' children were 65%, 61%, and 48%, respectively. Medical trainees had higher serostatus awareness, vaccination rate, and vaccination of their children than HCWs in other occupations (79% versus 62%, P < 0.001; 74% versus 58%, P < 0.001; and 62% versus 45%, P = 0.006, respectively). Cost was cited as the most frequent reason for non-vaccination. West African countries were more aware of their serostatus but less often vaccinated than East African countries (79% versus 59%, P < 0.0001 and 52% versus 60%, P = 0.03, respectively). West African countries cited cost as the reason for non-vaccination more than East African countries (59% versus 40%, P = 0.0003). Our study shows low HBV serostatus awareness and vaccination rate among HCWs in Africa, and reveals gaps in the perception and understanding of HBV prevention that should be addressed to protect HCWs and improve their capacity to control HBV infection.

Background and Aims: The coronavirus disease 19 (COVID-19) pandemic has spread rapidly around the globe with considerable morbidity and mortality. Coexistence of comorbidities with COVID-19 have consistently been reported as risk factors for unfavorable prognosis. We aim at this study to evaluate the impact of comorbidities in COVID-19 patients on the outcome and determine predictors of prolonged hospital stay, requisite for ICU admission or decease., Methods: Four hundreds and thirty nine adult patients who are admitted through (June and July 2020) in Assiut and Aswan University Hospitals were included in the study. All participants were diagnosed with COVID-19 according to Egyptian Ministry of Health guidance as definite case or Probable case. Detection of SARS-CoV-2 RNA was done by (TaqManâ"¢ 2019-nCoV Control Kit v1 (Cat. No. A47532) supplied by QIAGEN, Germany on the Applied Biosystem 7500 Fast RT PCR System, USA., Results: Patients with comorbidities represented 61.7% of all cases. Constitutional symptoms especially myalgia and LRT symptoms such as dyspnea were significantly higher in patients with comorbidities (P < 0.05). Patients with comorbidities had significantly worse laboratory parameters. ICU admission was higher in patients with comorbidities (35.8%). Among different comorbidities 45.4% of CVD cases were admitted in ICU followed by DM cases (40.8%). Also, patients with comorbidities needed invasive mechanical ventilation more than those without comorbidity (31 vs. 10.7%, P<0.001). Significant lower frequency of recovery was found in COVID-19 patients with comorbidities (59% vs. 81%, P<0.001) and death rate was significantly higher in cases with comorbidities (P< 0.001). The survival rates in cases with pre-existing CVD and neurological diseases were lower than those without disease (P<0.002 and 0.001 respectively)., Conclusion: Association of cardiovascular comorbid conditions including hypertension or neurological diseases together with COVID-19 infections carries higher risks of mortality. However, other comorbidities such as diabetes mellitus, chronic pulmonary or kidney diseases may also contribute to increased COVID-19 severity.

Egypt displays a high-hepatitis C virus (HCV) burden and almost 20% of the patients develop cutaneous manifestations HCV-related. Direct acting antivirals (DAAs) drastically changed HCV patient's morbidity and mortality but their impact of the cutaneous manifestations remains elusive. Our aim was to find out the prevalence of different dermatological manifestations accompaning HCV infection in Egyptian patients. Also, to highlight the impact of DAAs on such manifestations and any potential dermatological side effects. A descriptive study was carried out at the Department of Tropical medicine and Gastroenterology in collaboration with the Department of Dermatology, Venerology and Andrology, Assiut University Hospitals. Medical history, full general, dermatological examination and photography were performed for all patients before the start of treatment with the full regimen of DAAs, every month and 3 months after reaching sustained virological response (SVR), and the changes of skin lesions were recognized and rated by two blinded dermatologists. Out of 1000 examined patient, 36.9% had skin manifestation. Itching was the commonenst presented in 190 patients (51.5%). Three months after reaching SVR, skin examination revealed improvement in the majority of patients (23 764.22%). Pruritis had significant clinical improvement in 152(80%) of patients with significant change in the Visual Analog Score (P = .000). Also, patients with both cutaneous vasculitis and eczema experienced improvement in their skin manifestations. Skin manifestations are common in Egyptian patients with HCV infection. Pruritis is the commonest. The use of DAAs in treatment of HCV is associated with significant improvement of skin lesions with very limited cutaneous adverse effects., (© 2020 Wiley Periodicals LLC.)

Background and Study Aims: Determination of the presence and degree of liver fibrosis is essential for the prognosis and treatment of patients with chronic hepatitis C. Non-invasive methods of assessing fibrosis have been developed to reduce the need for biopsy. We determined the efficacy of shear wave elastography (SWE) and colour Doppler velocity as non-invasive methods for the assessment of liver fibrosis compared to liver biopsy among patients with chronic hepatitis C virus (HCV) infection., Patients and Methods: In total, 117 patients with chronic HCV infection and 50 healthy age- and sex-matched control subjects were included. For each patient and control, abdominal ultrasonography, Doppler ultrasonography of the right portal vein (PV), and SWE were performed, whereas liver biopsy was performed for patients., Results: The mean value of the right PV maximum velocity was lower in patients with different stages of fibrosis than in controls (p<0.001). The mean value of liver stiffness determined by SWE was significantly higher in patients with different stages of fibrosis than in controls. Cutoff values for liver stiffness determined by SWE for assessing fibrosis stages were F2⩾4.815, F3⩾6.335, and F4=7.540 with a sensitivity of 84.6%, 96.2%, and 100.0%; specificity of 88.5%, 93.8%, and 100.0%; positive predictive value (PPV) of 93.6%, 98.0%, and 100.0%; negative predictive value (NPV) of 74.2%, 88.2%, and 100.0%; and overall accuracy of 85.9%, 95.6%, and 100.0% [area under the ROC curve (AUC): 0.89, 0.96, and 1.0], respectively. Cutoff values for the right PV maximum velocity for assessing fibrosis stages were F2<23.4, F3<21, and F4<20 with a sensitivity of 65.0%, 57.4%, and 57.1%; specificity of 59.8%, 76.4%, and 75.5%; PPV of 33.8%, 58.3%, and 32.0%; NPV of 84.4%, 75.7%, and 89.7%; and overall accuracy of 61.1%, 69.5%, and 72.5% (AUC: 0.614, 0.696, and 0.625), respectively., Conclusion: SWE is effective for the non-invasive assessment of liver fibrosis in patients with HCV infection. SWE provides a more accurate correlation with liver fibrosis stage than colour Doppler velocity profile for the assessment of liver fibrosis, especially in advanced stages (F3 and F4)., (Copyright © 2017 Pan-Arab Association of Gastroenterology.

Background: Hepatocellular carcinoma is a leading cause of cancer-related death in Africa, but there is still no comprehensive description of the current status of its epidemiology in Africa. We therefore initiated an African hepatocellular carcinoma consortium aiming to describe the clinical presentation, management, and outcomes of patients with hepatocellular carcinoma in Africa., Methods: We did a multicentre, multicountry, retrospective observational cohort study, inviting investigators from the African Network for Gastrointestinal and Liver Diseases to participate in the consortium to develop hepatocellular carcinoma research databases and biospecimen repositories. Participating institutions were from Cameroon, Egypt, Ethiopia, Ghana, Ivory Coast, Nigeria, Sudan, Tanzania, and Uganda. Clinical information-demographic characteristics, cause of disease, liver-related blood tests, tumour characteristics, treatments, last follow-up date, and survival status-for patients diagnosed with hepatocellular carcinoma between Aug 1, 2006, and April 1, 2016, were extracted from medical records by participating investigators. Because patients from Egypt showed differences in characteristics compared with patients from the other countries, we divided patients into two groups for analysis; Egypt versus other African countries. We undertook a multifactorial analysis using the Cox proportional hazards model to identify factors affecting survival (assessed from the time of diagnosis to last known follow-up or death)., Findings: We obtained information for 2566 patients at 21 tertiary referral centres (two in Egypt, nine in Nigeria, four in Ghana, and one each in the Ivory Coast, Cameroon, Sudan, Ethiopia, Tanzania, and Uganda). 1251 patients were from Egypt and 1315 were from the other African countries (491 from Ghana, 363 from Nigeria, 277 from Ivory Coast, 59 from Cameroon, 51 from Sudan, 33 from Ethiopia, 21 from Tanzania, and 20 from Uganda). The median age at which hepatocellular carcinoma was diagnosed significantly later in Egypt than the other African countries (58 years [IQR 53-63] vs 46 years [36-58]; p<0·0001). Hepatitis C virus was the leading cause of hepatocellular carcinoma in Egypt (1054 [84%] of 1251 patients), and hepatitis B virus was the leading cause in the other African countries (597 [55%] of 1082 patients). Substantially fewer patients received treatment specifically for hepatocellular carcinoma in the other African countries than in Egypt (43 [3%] of 1315 vs 956 [76%] of 1251; p<0·0001). Among patients with survival information (605 [48%] of 1251 in Egypt and 583 [44%] of 1315 in other African countries), median survival was shorter in the other African countries than in Egypt (2·5 months [95% CI 2·0-3·1] vs 10·9 months [9·6-12·0]; p<0·0001). Factors independently associated with poor survival were: being from an African countries other than Egypt (hazard ratio [HR] 1·59 [95% CI 1·13-2·20]; p=0·01), hepatic encephalopathy (2·81 [1·72-4·42]; p=0·0004), diameter of the largest tumour (1·07 per cm increase [1·04-1·11]; p<0·0001), log α-fetoprotein (1·10 per unit increase [1·02-1·20]; p=0·0188), Eastern Cooperative Oncology Group performance status 3-4 (2·92 [2·13-3·93]; p<0·0001) and no treatment (1·79 [1·44-2·22]; p<0·0001)., Interpretation: Characteristics of hepatocellular carcinoma differ between Egypt and other African countries. The proportion of patients receiving specific treatment in other African countries was low and their outcomes were extremely poor. Urgent efforts are needed to develop health policy strategies to decrease the burden of hepatocellular carcinoma in Africa., Funding: None., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Aims: The study aimed to investigate the quantitative expression of NANOG, p38 α , NCF2, ELF and TGF-β genes in patients with colorectal adenocarcinoma, adenoma and normal colonic tissue and their correlation with SIRT-1 protein level expression., Method: This study enrolled one hundred sixty seven patients; group A: 87 patients with colonoscopic findings of no adenoma or adenocarcinoma and group B: 80 patients with colorectal mass. Consecutive colonoscopic examinations were conducted, and tissue samples were taken from the colonic lesions/masses. Total RNA was isolated and mRNA expression level of NANOG, mitogen activated p38α , Neutrophil Cytosol Factor 2 (NCF2), Embryonic Liver Fodrin (ELF) and Transforming Growth Factor Beta (TGF-β) genes were quantified by qRT-PCR. Sirt-1 protein expression level was assessed by quantitative western blot., Results: There were significantly high level of mRNA transcripts expression of the genes studied in patients with adenocarcinoma and adenoma compared with normal tissue (P value < 0.01), NANOG, NCF2, ELF and TGF-β at a cut of > 0.314, > 0.392, 0.349 and 0.333 respectively showed sensitivity (96.5%, 98.8%, 95.3%, 98.8%) and specificity of (95.3%, 92.6%, 89.5%, 93.8%) respectively in diagnosing colonic adenocarcinoma. Sirt-1 protein level was significantly highly expressed in colorectal adenocarcinoma compared to normal and adenoma colonic tissue and positively correlated with NANOG., Conclusion: Over expression of NANOG, p38α , NCF2, ELF and TGF-β genes in both cases of adenocarcinoma and adenoma could have a diagnostic value. SIRT-1 and NANOG are high correlated biological markers for diagnosis and prognosis follow up in patients with adenocarcinoma.

Aim: To assess the practice of Egyptian physicians in screening patients for hepatocellular carcinoma (HCC)., Methods: The study included 154 physicians from all over Egypt caring for patients at risk for HCC. The study was based on a questionnaire with 20 items. Each questionnaire consisted of two parts: (1) personal information regarding the physician (name, age, specialty and type of health care setting); and (2) professional experience in the care of patients at risk for HCC development (screening, knowledge about the cause and natural course of liver diseases and HCC risk)., Results: Sixty-eight percent of doctors with an MD degree, 48% of doctors with a master degree or a diploma and 40% of doctors with a Bachelor of Medicine, Bachelor of Surgery certificate considered the hepatitis C virus (HCV) genotype as risk factor for HCC development (P < 0.05). Ninety percent of physicians specialized in tropical medicine, internal medicine or gastroenterology and 67% of physicians in other specialties advise patients to undergo screening for HCV and hepatitis B virus infection as well as liver cirrhosis (P < 0.05). Eighty-six percent of doctors in University Hospitals and 69% of Ministry of Health (MOH) doctors consider HCV infection as the leading cause of HCC in Egypt (P < 0.05). Seventy-two percent of doctors with an MD degree, 55% of doctors with a master degree or a diploma, 56% of doctors with an MBBCH certificate, 74% of doctors in University Hospitals and 46% of MOH hospital doctors consider abdominal ultrasonography as the most important investigation in HCC screening (P < 0.05). Sixty-five percent of physicians in tropical medicine, internal medicine or gastroenterology and 37% of physicians in other specialties recommend as HCC screening interval of 3 mo (P < 0.05). Seventy-one percent of doctors with an MD degree, 50% of doctors with a master degree or diploma and 60% of doctors with an MBBCH certificate follow the same recommendation., Conclusion: In Egypt, physicians specialized in tropical medicine, internal medicine or gastroenterology with an MD degree and working in a University Hospital are best informed about HCC.

Background: End-stage liver disease (ESLD) is associated with dysregulation of the immune system and increased susceptibility to infections. Although invasive fungal infection (IFI) is a growing public health problem, studies of IFI in ESLD are lacking. The aims of this study were to screen for IFI in ESLD and to assess risk factors and serum interleukin 17 (IL-17) as a marker of the cellular immune response., Methods: Both blood and ascitic fluid samples were collected from 46 patients with ESLD for fungal culture and PCR. Serum IL-17 levels were determined., Results: Seven patients had isolated IFI (four had spontaneous fungal peritonitis, two had fungemia, and one had a disseminated fungal infection) and five cases had combined fungal and bacterial infections. Spontaneous fungal peritonitis was attributed to Candida species, while fungemia was caused by Aspergillus species. Patients with IFI had higher serum IL-17 levels and increased mortality compared to patients without IFI. A history of antibiotic use (p = 0.002), higher model for end-stage liver disease (MELD) scores (p = 0.04), and hepatorenal syndrome (p = 0.006) were risk factors for IFI., Conclusions: Patients with ESLD had a low frequency of IFI; however, in patients with these infections, delayed diagnosis and treatment may contribute to a high fatality rate. Thus, clinicians should have a high index of suspicion for this unusual but lethal entity, as prompt detection and appropriate treatment can improve the outcome., (Copyright © 2014 The Authors.
