Nonalcoholic Fatty Liver Disease-Related Hepatocellular Carcinoma: The Next Threat after Viral Hepatitis.

For many years, we have faced the complications of viral hepatitis and alcohol-related liver diseases such as cirrhosis, decompensation, portal hypertension, and hepatocellular carcinoma (HCC). Recently, we have seen a dynamic change in the field of hepatology. With the significant achievements in eradicating the hepatitis C virus by direct-acting antiviral agents and the rising epidemic of obesity, diabetes mellitus, and metabolic syndrome, there is a paradigm shift in the leading cause of liver cirrhosis and cancer to nonalcoholic fatty liver disease (NAFLD). Current data highlight the rapidly rising incidence of NAFLD-related HCC worldwide and expose the unseen part of the iceberg. In this review, we aim to update knowledge about the pathogenesis of NAFLD-induced HCC, surveillance difficulties, and promising disease markers. Molecular biomarkers, for example, may become a promising cornerstone for risk-stratified surveillance, early detection, and treatment selection for NAFLD-related HCC. Physicians can offer personalized and tailor-made clinical decisions for this unique patient subgroup.

Vibration Controlled Transient Elastography in Screening for Silent Liver Diseases.

OBJECTIVES: The objective of this study was to screen for significant hepatic fibrosis or steatosis in asymptomatic, apparently healthy subjects by using Vibration-controlled transient elastography and controlled attenuation parameter (CAP). METHODS: Prospectively, 433 asymptomatic apparently healthy adults were included. Fibroscan/CAP examination was performed for all of them. Subjects with liver stiffness measurement > 6 kPa or CAP >248 dB/m were further evaluated to assess underlying chronic liver disease. RESULTS: According to fibroscan/CAP examination, subjects were classified into four subgroups: normal (119) with CAP score of 215.85 ± 24.81 dB/m and fibrosis score of 4.47 ± 0.81 kPa, subjects with steatosis only 133 with CAP score of 309.41 ± 42.6 dB/m and fibrosis score of 4.74 ± 0.82 kPa, subjects with both steatosis and fibrosis 95 with CAP score of 318.20 ± 39.89 dB/m and fibrosis score of 7.92 ± 2.58 kPaand subjects with fibrosis only 86 with CAP score of 213.48 ± 22.62 dB/m and fibrosis score of 6.96 ± 1.11 kPa. S0 was present in 205 (47.3%), S1 in 48 (10.2%), S2 in 16 (3.7%) and S3 in 168 (38.8%) of studied subjects, whereas F0-1 was present in 371 (85.7%), F2 in 44 (10.16%), F3 in 16 (3.7%) subjects and F4 in only one (0.23%) subject. Subjects with both steatosis and fibrosis showed significantly higher transaminases, triglycerides and total cholesterol levels than other subgroups. CONCLUSIONS: Most asymptomatic, apparently healthy subjects (72%) have significant steatosis and fibrosis. Liver stiffness measurement and CAP might represent promising first-line noninvasive procedures to screen for silent liver diseases in the general population.

Non-pulmonary involvement in COVID-19: A systemic disease rather than a pure respiratory infection.

During the early phase of the coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), diagnosis was difficult due to the diversity in symptoms and imaging findings and the variability of disease presentation. Pulmonary manifestations are reportedly the main clinical presentations of COVID-19 patients. Scientists are working hard on a myriad of clinical, epidemiological, and biological aspects to better understand SARS-CoV-2 infection, aiming to mitigate the ongoing disaster. Many reports have documented the involvement of various body systems and organs apart from the respiratory tract including the gastrointestinal, liver, immune system, renal, and neurological systems. Such involvement will result in diverse presentations related to effects on these systems. Other presentations such as coagulation defects and cutaneous manifestation may also occur. Patients with specific comorbidities including obesity, diabetes, and hypertension have increased morbidity and mortality risks with COVID-19.

Anxiety, depression and coping strategies among chronic medical patients with coronavirus disease-2019: a multicenter follow-up cohort study.

BACKGROUND: Studies have shown that COVID-19 patients experience high levels of anxiety, depression, and stress during the pandemic. Patients adopt different coping strategies to reduce their psychological distress. AIM: To compare the immediate and long-term psychological impact of COVID-19 disease on patients with and without chronic medical illnesses (CMI) and identify coping styles of both groups during the peak of COVID-19 disease in Egypt. METHODS: This is a cohort follow-up study, that included an online survey consisting of General Health Questionnaire-12, Taylor Manifest Anxiety Scale, Beck Depression Inventory and Brief-COPE scale. The Post-Traumatic Stress Disorder (PTSD) Checklist was completed after 6 months. Questionnaires were distributed to adult patients with a confirmed diagnosis of SARS-CoV-2 virus infection during their quarantine in Egypt. RESULTS: There was no significant difference between the two groups regarding anxiety and depression during the acute infection. Patients without CMI relied significantly on the use of informational support to cope with COVID-19 disease. Patients with CMI continued to show significant depressive symptoms after 6 months without significant PTSD symptoms. CONCLUSIONS: COVID-19 has similar immediate psychological impact on patients with and without CMI. However, patients with CMI continue to show depression on long-term follow-up.

Clinical characteristics and predictors of esophagogastric variceal bleeding among patients with HCV-induced liver cirrhosis: An observational comparative study.

OBJECTIVES: To investigate the clinical characteristics, risk factors, and predictors of esophagogastric variceal bleeding in patients with hepatitis C virus (HCV)-induced liver cirrhosis. METHODS: This comparative observational study was carried out on 100 patients suffering from post hepatitis cirrhosis and portal hypertension who were admitted to the Internal Medicine Department, Al-Azhar University Hospital, Damietta Egypt. Patients were classified into two groups: 50 of them presented with esophagogastric varices with acute variceal bleeding, and 50 patients presented without bleeding. Data were collected, coded, revised, and entered into the Stata software version 16. RESULTS: The mean age of patients with bleeding was slightly higher than those without bleeding (55.58 ± 5.89 vs. 52.54 ± 9.01 years), p = 0.049. Mild ascites, positive H.Pylori, and Child-Pugh score B and C were an independent predictors of esophagogastric variceal bleeding (OR = 0.036, 95% CI: 0.0004-0.36; p = 0.005), (OR = 7.36, 95% CI: 1.44-37.59; p = 0.016), (OR = 19.0, 95% CI: 2.02-186.3; p = 0.010), and (OR = 40.51, 95% CI: 2.18-751.31; p = 0.013). The sensitivity of this model was 93.88%, specificity was 53.85%, PPV was 88.46%, NPV was 70.0%, correctly classified patients were 85.48%, and AUC was 90.27%. In the second model, pepsinogen level higher than 43.5 µg/l, AST (>54.5), Bilirubin (>1.45), and Hemoglobin (>11.5) were a significant independent predictors of esophagogastric variceal bleeding (OR = 1.18, 95% CI: 1.09-1.27; p<0.001), (OR = 1.14, 95% CI: 1.03-1.27; p = 0.007), (OR = 5.55, 95% CI: 1.21-25.43; p = 0.027), and (OR = 0.05, 95% CI: 0.008-0.32; p = 0.002), respectively. The sensitivity of this model was 92%, specificity was 98%, PPV was 97.87%, NPV was 92.45%, correctly classified patients were 95%, and AUC was 98.68%. CONCLUSION: The independent predictors of esophagogastric variceal bleeding were ascites, positive H. pylori, Child-Pugh score B and C, pepsinogen level higher than 43.5 µg/l, AST (>54.5), bilirubin (>1.45), and hemoglobin (>11.5). Laboratory investigations are more reliable in predicting variceal bleeding and excluding non-variceal bleeding; however, clinical symptoms should not be neglected, especially H. pylori infection, ascites, and Child-Pugh score.

Hemostatic system and COVID-19 crosstalk: A review of the available evidence.

Since the discovery of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its resultant coronavirus disease 2019 (COVID-19) pandemic, respiratory manifestations have been the mainstay of clinical diagnosis, laboratory evaluations, and radiological investigations. As time passed, other pathological aspects of SARS-CoV-2 have been revealed. Various hemostatic abnormalities have been reported since the rise of the pandemic, which was sometimes superficial, transient, or fatal. Mild thrombocytopenia, thrombocytosis, venous, arterial thromboembolism, and disseminated intravascular coagulation are among the many hemostatic events associated with COVID-19. Venous thromboembolism necessitating therapeutic doses of anticoagulants is more frequently seen in severe cases of COVID-19, especially in patients admitted to intensive care units. Hemorrhagic complications rarely arise in COVID-19 patients either due to a hemostatic imbalance resulting from severe disease or as a complication of over anticoagulation. Although the pathogenesis of coagulation disturbance in SARS-CoV-2 infection is not yet understood, professional societies recommend prophylactic antithrombotic therapy in severe cases, especially in the presence of abnormal coagulation indices. The review article discusses the various available evidence on coagulation disorders, management strategies, outcomes, and prognosis associated with COVID-19 coagulopathy, which raises awareness about the importance of anticoagulation therapy for COVID-19 patients to guard against possible thromboembolic events.

Quality indicators for colonoscopy in Egypt: A prospective multicenter study.

BACKGROUND AND STUDY AIMS: Despite its wide availability, we do not have sufficient data aboutthe quality of colonoscopy in Egypt. In this study, we proposed 13 indicators to assess the quality of colonoscopy procedures in the included study centers aiming to attain a representative image of the quality of CS in Egypt. PATIENTS AND METHODS: A multicenter prospective study was conducted between July and December 2020, which included all patients who underwent colonoscopy in the participating centers. The following were the proposed quality indicators: indications for colonoscopy, preprocedure clinical assessment, obtaining written informed consent, adequate colon preparation, sedation, cecal intubation rate (CIR), withdrawal time, adenoma detection rate (ADR), complication rate, photographic documentation, automated sterilization, regular infection control check, and well-equipped postprocedure recovery room. RESULT: A total of 1,006 colonoscopy procedures were performed during the study duration in the included centers. Our analysis showed the following four indicators that were fulfilled in all centers: appropriate indications for colonoscopy, preprocedure assessment, written informed consent, and automated sterilization. However, photographic documentation and postprocedure follow-up room were fulfilled only in 57 %. Furthermore, 71 % of the centers performed regular infection control checks. Adequate colon preparation was achieved in 61 % of the procedures, 81 % of the procedures were performed under sedation, 95.4 % CIR, 11-min mean withdrawal time, 15 % ADR, and 0.1 % overall complication rate. Statistically significant factors affecting CIR were age > 40 years, high-definition endoscope, previous colon intervention, and rectal bleeding, whereas those affecting ADR were age > 40 years, the use of image enhancement, previous colon intervention, rectal bleeding, the use of water pump, and a withdrawal time of > 9 min. CONCLUSION: Our study revealed the bright aspects of colonoscopy practice in Egypt, including high CIRs and low complication rates; conversely, ADR, bowel cleansing quality, and infection control measures should be improved.

Clinico-Epidemiological Characteristics of Patients With Inflammatory Bowel Disease in Egypt: A Nationwide Multicenter Study.

Background and Aims: Ulcerative colitis (UC) and Crohn's disease (CD) are the most common types of Inflammatory bowel disease (IBD), with variable responses to traditional therapies and unpredicted prognosis. In Egypt and most developing countries, the lack of recent epidemiological and prognostic data adversely affects management strategies. We collected and analyzed data of patients with IBD from multiple centers across Egypt to evaluate patients' clinical and epidemiological characteristics. Methods: This retrospective multicenter study included patients diagnosed with IBD between May 2018 and August 2021, at 14 tertiary gastroenterology units across Egypt. Record analysis addressed a combination of clinico-epidemiological characteristics, biochemical tests, stool markers, endoscopic features, histological information, and different lines for IBD treatment. Results: We identified 1104 patients with an established diagnosis of IBD; 81% of them had UC, and 19% showed CD. The mean age of onset was 35.1 ± 12.5 years ranging from 5 to 88 years, the mean duration of illness at inclusion was 13.6 ± 16.7 years, gender distribution was almost equal with a significant male dominance (60.4%, p = 0.003) among patients with CD, 57% were living in rural areas, and 70.5% were from Delta and Coastal areas. Two hundred nineteen patients (19.8%) displayed comorbid conditions, primarily associated with CD. The most frequent complaints were diarrhea (73.2%), rectal bleeding (54.6%) that was significantly higher among patients with UC (64%, p < 0.001), and 46.8% with abdominal pain (more often with CD: 71%, p < 0.001). Conventional therapy was effective in treating 94.7% of patients. The main lesion in patients with CD was ileal (47.8%); patients with UC mainly exhibited proctosigmoiditis (28.4%). Dysplasia was detected in 7.2% of patients, mainly subjects with UC. Conclusions: To our knowledge, our effort is the first and largest cohort of Egyptian patients with IBD to describe clinical and epidemiological characteristics, and diagnostic and management approaches. More extensive prospective studies are still needed to fully characterize disease distribution, environmental factors, and pathological features of the disease.

Prediction of mortality in hospitalized Egyptian patients with Coronavirus disease-2019: A multicenter retrospective study.

We aimed to assess the epidemiological, clinical, and laboratory characteristics associated with mortality among hospitalized Egyptian patients with COVID-19. A multicenter, retrospective study was conducted on all polymerase chain reaction (PCR)-confirmed COVID-19 cases admitted through the period from April to July 2020. A generalized linear model was reconstructed with covariates based on predictor's statistical significance and clinically relevance. The odds ratio (OR) was calculated by using stepwise logistic regression modeling. A total of 3712 hospitalized patients were included; of them, 900 deaths were recorded (24.2%). Compared to survived patients, non-survived patients were more likely to be older than 60 years (65.7%), males (53.6%) diabetic (37.6%), hypertensive (37.2%), and had chronic renal insufficiency (9%). Non-survived patients were less likely to receive azithromycin (p <0.001), anticoagulants (p <0.001), and steroids (p <0.001). We found that age ≥ 60 years old (OR = 2.82, 95% CI 2.05-3.86; p <0.0001), diabetes mellitus (OR = 1.58, 95% CI 1.14-2.19; p = 0.006), hypertension (OR = 1.69, 95% CI 1.22-2.36; p = 0.002), chronic renal insufficiency (OR = 3.15, 95% CI 1.84-5.38; p <0.0001), tachycardia (OR = 1.65, 95% CI 1.22-2.23; p <0.001), hypoxemia (OR = 5.69, 95% CI 4.05-7.98; p <0.0001), GCS <13 (OR 515.2, 95% CI 148.5-1786.9; p <0.0001), the use of therapeutic dose of anticoagulation (OR = 0.4, 95% CI 0.22-0.74, p = 0.003) and azithromycin (OR = 0.16, 95% CI 0.09-0.26; p <0.0001) were independent negative predictors of mortality. In conclusion, age >60 years, comorbidities, tachycardia, hypoxemia, and altered consciousness level are independent predictors of mortality among Egyptian hospitalized patients with COVID-19. On the other hand, the use of anticoagulants and azithromycin is associated with reduced mortality.

High success rates for the use of ombitasvir/paritaprevir/ritonavir containing regimens in treatment of naïve and experienced chronic hepatitis C genotype 4: Real world results.

INTRODUCTION AND AIMS: Treatment of hepatitis C virus (HCV) genotype 4 patient with fixed dose combination of ombitasvir-paritaprevir-ritonavir plus ribavirin (OBV/rPTV/RBV) has been proven efficacy and safety in many clinical trials. The current study reports the efficacy and safety of OBV/rPTV/RBV (for treatment-naïve), and OBV/rPTV/RBV/sofosbuvir (SOF) (for treatment-experienced), in chronic HCV genotype 4 patients in real life settings. METHODS: Prospective cohort study including all adult chronic HCV genotype 4 patients who were scheduled to receive OBV/rPTV/RBV ± SOF for 12 or 24 weeks in New Cairo Viral Hepatitis Treatment Center. The primary efficacy endpoint was a virologic response at posttreatment week 12 (SVR12). Changes in hematological parameters, liver biochemical profile and fibrosis-4 index (FIB-4), as well as clinical and laboratory adverse events (AEs) across follow up visits (week 4, end of treatment [EOT], and SVR12), were recorded. RESULTS: Our study included 325 patients (age; 47.63 ± 12.63 years, 55.38% [n = 180] men). Most of the included patients (89.85%, n = 292) were treatment naïve and only 7% (n = 23) had liver cirrhosis. Overall, SVR12 was attained by 98.44% (316 of 321) of the patients; 97.15% (307 of 316) of patients who received 12 weeks of OBV/rPTV/RBV ± SOF and 100% (9 of 9) of patients who received 24 weeks of OBV/rPTV/RBV as assessed by modified intention to treat analysis. There was a significant improvement of baseline alanine aminotransferase, aspartate aminotransferase, hemoglobin, FIB-4 at SVR12 (P < 0.05). The most common reported AEs were anemia (n = 106), fatigue (n = 41) and elevated indirect bilirubin (n = 37). CONCLUSION: OBV/rPTV/RBV (±SOF) is a highly effective therapy for chronic HCV patients in real life settings.

Survival and outcomes for co-infection of chronic hepatitis C with and without cirrhosis and COVID-19: A multicenter retrospective study.

BACKGROUND: Chronic liver disease, particularly cirrhosis, is associated with worse outcomes in patients infected with coronavirus disease 2019 (COVID-19). AIM: To assess outcomes of COVID-19 infection among patients with pre-existing hepatitis C with or without liver cirrhosis. METHODS: This multicenter, retrospective cohort study included all cases of confirmed co-infection of severe acute respiratory syndrome coronavirus 2 and chronic hepatitis C with or without liver cirrhosis who were admitted to six hospitals (Al-Sahel Hospital, Al-Matareya Hospital, Al-Ahrar Hospital, Ahmed Maher Teaching Hospital, Al-Gomhoreya Hospital, and the National Hepatology and Tropical Medicine Research Institute) affiliated with the General Organization for Teaching Hospitals and Institutes in Egypt. Patients were recruited from May 1, 2020, to July 31, 2020. Demographic, laboratory, imaging features, and outcomes were collected. Multivariate regression analysis was performed to detect factors affecting mortality. RESULTS: This retrospective cohort study included 125 patients with chronic hepatitis C and COVID-19 co-infection, of which 64 (51.20%) had liver cirrhosis and 40 (32.00%) died. Fever, cough, dyspnea, and fatigue were the most frequent symptoms in patients with liver cirrhosis. Cough, sore throat, fatigue, myalgia, and diarrhea were significantly more common in patients with liver cirrhosis than in non-cirrhotic patients. There was no difference between patients with and without cirrhosis regarding comorbidities. Fifteen patients (23.40%) with liver cirrhosis presented with hepatic encephalopathy. Patients with liver cirrhosis were more likely than non-cirrhotic patients to have combined ground-glass opacities and consolidations in CT chest scans: 28 (43.75%) vs 4 (6.55%), respectively (P value < 0.001). These patients also were more likely to have severe COVID-19 infection, compared to patients without liver cirrhosis: 29 (45.31%) vs 11 (18.04%), respectively (P value < 0.003). Mortality was higher in patients with liver cirrhosis, compared to those with no cirrhosis: 33 (51.56%) vs 9 (14.75%), respectively (P value < 0.001). All patients in Child-Pugh class A recovered and were discharged. Cirrhotic mortality occurred among decompensated patients only. A multivariate regression analysis revealed the following independent factors affecting mortality: Male gender (OR 7.17, 95%CI: 2.19-23.51; P value = 0.001), diabetes mellitus (OR 4.03, 95%CI: 1.49-10.91; P value = 0.006), and liver cirrhosis (OR 1.103, 95%CI: 1.037-1.282; P value < 0.0001). We found no differences in liver function, COVID-19 disease severity, or outcomes between patients who previously received direct-acting antiviral therapy (and achieved sustained virological response) and patients who did not receive this therapy. CONCLUSION: Patients with liver cirrhosis are susceptible to higher severity and mortality if infected with COVID-19. Male gender, diabetes mellitus, and liver cirrhosis are independent factors associated with increased mortality risk.

Hepatic and gastrointestinal disturbances in Egyptian patients infected with coronavirus disease 2019: A multicentre cohort study.

BACKGROUND: Various liver and gastrointestinal involvements occur in patients with coronavirus disease 2019 (COVID-19) at variable prevalence. Most studies report mild liver function disturbances correlated with COVID-19 severity, though liver failure is unusual. AIM: To study liver and gastrointestinal dysfunctions in Egyptian patients with COVID-19 and their relation to disease outcomes. METHODS: This multicentre cohort study was conducted on 547 Egyptian patients from April 15, 2020 to July 29, 2020. Consecutive polymerase chain reaction-confirmed COVID-19 cases were included from four quarantine hospitals affiliated to the Egyptian ministry of health. Demographic information, laboratory characteristics, treatments, fibrosis-4 (FIB-4) index, COVID-19 severity, and outcomes were recorded and compared according to the degree of liver enzyme elevation and the presence of gastrointestinal symptoms. Follow-ups were conducted until discharge or death. Regression analyses were performed to determine the independent factors affecting mortality. RESULTS: This study included 547 patients, of whom 53 (9.68%) died during hospitalization and 1 was discharged upon his request. Patients' mean age was 45.04 ± 17.61 years, and 21.98% had severe or critical COVID-19. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were available for 430 and 428 patients, respectively. In total, 26% and 32% of patients had elevated ALT and AST, respectively. Significant liver injury with ALT or AST elevation exceeding 3-fold was recorded in 21 (4.91%) and 16 (3.73%) patients, respectively. Male gender, smoking, hypertension, chronic hepatitis C, and lung involvement were associated with elevated AST or ALT. AST was elevated in 50% of patients over 60-years-old. FIB-4 was significantly higher in patients admitted to the intensive care unit (ICU), those with more severe COVID-19, and non-survivors. The independent variables affecting outcome were supplementary vitamin C intake (1 g daily capsules) [odds ratio (OR): 0.05, 95% confidence interval (CI): 0.008-0.337]; lung consolidation (OR: 4.540, 95%CI: 1.155-17.840); ICU admission (OR: 25.032, 95%CI: 7.110-88.128); and FIB-4 score > 3.25 (OR: 10.393, 95%CI: 2.459-43.925). Among 60 (13.98%) patients with gastrointestinal symptoms, 52 (86.67%) had diarrhoea. Patients with gastrointestinal symptoms were predominantly females with higher body mass index, and 50 (83.40%) patients had non-severe COVID-19. CONCLUSION: Few Egyptian patients with COVID-19 developed a significant liver injury. The independent variables affecting mortality were supplementary vitamin C intake, lung consolidation, ICU admission, and FIB-4 score.

Safety and efficacy of sofosbuvir/ledipasvir and sofosbuvir/daclatasvir in the treatment of hepatitis C in patients with decompensated cirrhosis.

BACKGROUND: Hepatitis C virus (HCV)-related decompensated cirrhosis is a severe life-threatening illness. The safety of direct-acting antivirals (DAAs) has opened a gate of hope for that subgroup of patients who were previously contraindicated for interferon therapy. OBJECTIVE: We aimed at the investigation of the safety and efficacy of different DAAs regimens in the treatment of HCV-related decompensated cirrhosis patients, to determine sustained virological response (SVR)12 rates and to analyze the factors associated with response. METHODS: A retrospective, single-center study including HCV-related decompensated cirrhosis patients who received DAAs. Demographic, laboratory and clinical data were analyzed. The SVR12 rate was the primary outcome measure. Secondary outcomes included the predictors of response, changes in the baseline model for end-stage liver disease and child-turcotte-pugh (CTP) scores, and fibroindices (APRI and fibrosis-4 index) at 12 weeks after treatment. RESULTS: In total, 145 eligible patients (141 with CTP class B and 4 with class C) were enrolled in this study. SVR12 was achieved by 88.06% (118/134) of efficacy population on different DAAs regimens, Treatment was discontinued in 11 patients because of severe side effects without any deaths. Younger age showed a significant positive association with SVR12. CONCLUSIONS: DAAs can be used for the treatment of HCV-related decompensated liver disease, with acceptable SVR12 rates and safety profiles.

Predictors of severity and development of critical illness of Egyptian COVID-19 patients: A multicenter study.

OBJECTIVES: We conducted the present multicenter, retrospective study to assess the epidemiological, clinical, laboratory, and radiological characteristics associated with critical illness among patients with COVID-19 from Egypt. METHODS: The present study was a multicenter, retrospective study that retrieved the data of all Egyptian cases with confirmed COVID-19 admitted to hospitals affiliated to the General Organization for Teaching Hospitals and Institutes (GOTHI) through the period from March to July 2020. The diagnosis of COVID-19 was based on a positive reverse transcription-polymerase chain reaction (RT-PCR) laboratory test. RESULTS: This retrospective study included 2724 COVID-19 patients, of whom 423 (15.52%) were critically ill. Approximately 45.86% of the critical group aged above 60 years, compared to 39.59% in the non-critical group (p = 0.016). Multivariate analysis showed that many factors were predictors of critically illness, including age >60 years (OR = 1.30, 95% CI [1.05, 1.61], p = 0.014), low oxygen saturation (OR = 0.93, 95% CI [0.91, 0.95], p<0.001), low Glasgow coma scale (OR = 0.75, 95% CI [0.67, 0.84], p<0.001), diabetes (OR = 1.62, 95% CI [1.26, 2.08], p<0.001), cancer (OR = 2.47, 95% CI [1.41, 4.35], p = 0.002), and serum ferritin (OR = 1.004, 95% CI [1.0003, 1.008], p = 0.031). CONCLUSION: In the present report, we demonstrated that many factors are associated with COVID-19 critical illness, including older age groups, fatigue, elevated temperature, increased pulse, lower oxygen saturation, the preexistence of diabetes, malignancies, cardiovascular disease, renal diseases, and pulmonary disease. Moreover, elevated serum levels of ALT, AST, and ferritin are associated with worse outcomes. Further studies are required to identify independent predictors of mortality for patients with COVID-19.

Weekend and evening planned colonoscopy activity: a safe and effective way to meet demands.

Background and study aims Colonoscopy is the "gold standard" investigation for assessment of the large bowel that detects and prevents colorectal cancer, as well as non-neoplastic conditions. The Joint Advisory Group (JAG) on Gastrointestinal Endoscopy recommends monitoring key performance indicators such as cecal intubation rate (CIR) and adenoma detection rate (ADR). We aimed to investigate the quality of colonoscopies carried out during evening and Saturday lists in our unit and compare them against JAG standards of quality for colonoscopies. Patients and methods We retrospectively collected and analyzed demographical and procedure-related data for non-screening colonoscopies performed between January 2016 and November 2018. Evenings and Saturdays were defined as the out-of-hour (OOH) period. We compared the outcomes of the procedures done in these against the working hours of the weekdays. We also wanted to explore whether the outcomes were different among certain endoscopists. Other factors that could affect the KPIs, such as endoscopist experience and bowel preparation, were also analyzed. Results There were a total of 17634 colonoscopies carried out; 56.9 % of the patients (n = 10041) < 70 years old. Key Performance Indicators (KPIs) of weekday, evening, and Saturday colonoscopies regarding the CIR and ADR met the JAG standards as they were above 93 % and 24 %, respectively. Advanced colonoscopists had better KPIs when compared to the non-advanced colonoscopists, with CIR at 97.6 % vs. 93.2 % and ADR at 40.8 % vs. 26 %, respectively. Conclusions JAG standards were maintained during colonoscopies done on weekdays, evenings, and Saturdays. Advanced colonoscopists had higher CIR and ADRs.

Gastrointestinal manifestations of human immunodeficiency virus and coronavirus disease 2019: Understanding the intersecting regions between the two epidemics.

In March 2020, the World Health Organization declared coronavirus disease (COVID-19) a pandemic. As of February 2021, there were 107 million COVID-19 cases worldwide. As a comparison, there are approximately 38 million people living with human immunodeficiency virus (PLHIV) worldwide. The coexistence of both epidemics, and the syndemic effect of both viruses could lead to a delirious impact both at individual and community levels. Many intersecting points were found between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19, and HIV; among which, gastrointestinal (GI) manifestations are the most notable. GI manifestations represent a common clinical presentation in both HIV and SARS-CoV-2. The emergence of GI symptoms as a result of SARS-CoV-2 infection provides a new dynamic to COVID-19 diagnosis, management, and infection control measures, and adds an additional diagnostic challenge in case of coinfection with HIV. The presence of GI manifestations in PLHIV during the COVID-19 pandemic could be referred to HIV enteropathy, presence of opportunistic infection, adverse effect of antiretrovirals, or coinfection with COVID-19. Thus, it is important to exclude SARS-CoV-2 in patients who present with new-onset GI manifestations, especially in PLHIV, to avoid the risk of disease transmission during endoscopic interventions. Structural similarities between both viruses adds a valuable intersecting point, which has mutual benefits in the management of both viruses. These similarities led to the hypothesis that antiretrovirals such as lopinavir/Rironavir have a role in the management of COVID-19, which was the target of our search strategy using the available evidence. These similarities may also facilitate the development of an efficient HIV vaccine in the future using the advances in COVID-19 vaccine development.

Liver transplantation in the era of COVID-19.

Liver transplantation is considered the ultimate solution for patients with end-stage chronic liver disease or acute liver failure. Patients with liver transplant need special care starting from preoperative preparation, surgical intervention ending with postoperative care. Transplanted patients have to receive immunosuppressive therapy to prevent rejection. Such a state of immune suppression could predispose to different types of infections in liver transplant recipients. Currently, the world is suffering a pandemic caused by a new strain of the coronavirus family called COVID-19. Certain infection control precautions are needed to protect immunocompromised and vulnerable patients, including liver transplant candidates and recipients from acquiring COVID-19 infection. Restricting non-transplant elective surgical procedures, managing transplant patients in separate outpatient clinics, and in-patient wards can prevent transmission of infection both to patients and healthcare workers. Telemedicine can help in the triage of patients to screen for symptoms of COVID-19 before their regular appointment. Management of immunosuppressive therapy and drug-drug interactions in liver transplant recipients infected with COVID-19 should be cautiously practiced to prevent rejection and effectively treat the underlying infection. In this report, we are trying to summarize available evidence about different aspects of the management of liver transplant candidates and recipients in the era of COVID-19.

Egyptian liver library: An indexed database for liver disease evidence in Egypt.

Liver diseases are among the most challenging health care problems worldwide. In Egypt, we established different care programs to combat liver diseases including schistosomiasis and viral hepatitides. A lot of research work addressing liver diseases in Egypt have been published with special focus on these two major fields. Other liver disease seems to be neglected although present and contributing to the liver disease burden in Egypt. In this report we reviewed the available evidence published from Egypt and elucidate areas of weakness and future research needs. Our search for Egyptian liver disease evidence retrieved 4683 articles, 67% of them were relevant to the topic. Out of the relevant articles; 1646/3265 (50.4%) were discussing clinical science, 1131 (34.7%) were discussing basic science and 488 (14.9%) were discussing both basic and clinical sciences. Cairo university (16.8%, n = 513) and Mansoura university (9.3%, n = 285) had the largest number of publications related to liver disease in Egypt respectively. The most commonly reported diseases were hepatitis C in 719/3361 articles (21.4%), parasitic liver infestations in 663 articles (19.7%), hepatocellular carcinoma in 544 articles (16.2%), liver fibrosis or cirrhosis in 537 articles (16%), and drug induced liver injury in 516 articles (15.4%). Most of the reviewed articles (36%) were discussing treatment of chronic liver diseases (n = 1201) followed by diagnostics (28%, n = 940), pathogenesis and pathophysiology (21%, n = 706). This review will direct attention to areas with less research like hepatitis B related liver disease, HIV/HCV co-infections, and non-alcoholic fatty liver disease (NAFLD) to encourage future research in these topics. In conclusion; our results ring a bell inviting the development of a roadmap for liver research in Egypt targeting to put future policies to cover areas of weakness in liver research with an ultimate goal of tackling liver disease and its overwhelming socioeconomic burden in our developing country.

Clinical impact of serum α-fetoprotein and its relation on changes in liver fibrosis in hepatitis C virus patients receiving direct-acting antivirals.

BACKGROUND: α-Fetoprotein (AFP) is used widely as a serological marker for hepatocellular carcinoma. However, the AFP value is elevated in chronic hepatitis C virus (HCV) patients without hepatocellular carcinoma. Yet, data on the impact of direct-acting antiviral agents (DAAs) therapy on AFP levels after viral eradication are still lacking. AIM: The aim of this study was to elucidate the changes in the serum AFP level in chronic hepatitis C patients treated with DAA-based therapy and their relation to response and liver fibrosis parameters. PATIENTS AND METHODS: A total of 456 chronic HCV patients who received different DAAs-based treatment regimens were enrolled. Laboratory data including serum AFP, transient elastography values, and fibrosis scores were recorded at baseline and sustained virological response at 24 weeks after treatment (SVR24). The outcome was the changes in the AFP level from baseline to SVR24 and its relation to changes in liver fibrosis parameters at SVR24 using Spearman's rank correlation test. RESULTS: Overall, 96.9% of enrolled patients were responders. A statistically significant improvement in serum transaminases, albumin, transient elastography values, and fibrosis scores at SVR24 was reported. The AFP level was significantly decreased from a median (interquartile range) of 6 (3.2-10.8) ng/ml before DAAs to 4 (2.3-6) ng/ml at SVR24 (P < 0.0001). Only 22.6% of patients showed an increase in the AFP level after treatment. On multivariate analysis, the only independent baseline variable associated with an increase in the AFP level after treatment was baseline AFP (odds ratio: 0.95, 95% confidence interval: 0.91-0.99, P = 0.02). There is a significant correlation between changes in AFP and liver fibrosis parameters at SVR24. CONCLUSION: DAAs-based regimens are a highly efficient antiviral therapy for chronic hepatitis C patients that resulted in improvements in the serum AFP level.
