Background The latest novel corona virus disease (COVID-19) pandemic shows a significant health concern. We aimed to study the prevalence of gastrointestinal symptoms among COVID-19 Egyptian patients. Methods A cross-sectional study was carried out on 860 patients with COVID-19 infection classified according to Ministry of Health Program (MOHP) into three groups (280 patients with mild disease, 258 patients with moderate disease and 322 patients with severe disease). All patients were subjected to medical history, clinical examination, laboratory investigations, high-resolution computed tomography chest (HRCT chest) and other investigations when needed in some patients e.g., upper gastro-intestinal (GI) endoscopy, abdomino-pelvic ultrasound and ECHO. Results Gastro-intestinal symptoms were present in 27.2% of the studied patients. The most common reported GIT symptoms were vomiting, diarrhea, abdominal/gastric pain, followed by nausea.GIT symptoms presence was significantly higher in severe cases in comparison to mild or moderate cases. C-reactive protein (CRP), serum ferritin, Aspartate aminotransferase (AST), bilirubin and creatinine were significantly associated with the presence of GI symptoms. Conclusions GI symptoms are prevalent among COVID-19 patients, the most common which were vomiting and diarrhea and were associated with COVID-19 severity.
Background: Several precipitating factors of hepatic encephalopathy have been recognized and studied. Hepatic encephalopathy which is a frequent and grave complication of liver failure, is associated with multiple biochemical changes like high serum ammonia, mercaptan and phenol levels, low albumin levels and derangements in electrolytes. It is characterized by a range of neuronal and psychological aberrations mainly due to the inability of liver to metabolize different neurotoxic chemicals produced in the body. Hypokalemia is one of the most important findings in hepatic encephalopathy and postulated as a precipitating factor of the condition. The authors aimed to know the frequency of hypokalemia and its relation to the severity of hepatic encephalopathy. Methods: After taking approval from the hospital ethical review committee, a total of 5000 patients with hepatic encephalopathy were recruited by consecutive sampling. They were interviewed, examined and investigated for serum potassium levels and other precipitating factors of hepatic encephalopathy. Results: Total of 5000 patients including 3070 (61.4%) males and 1930 (38.6%) females, aging 13 years and above were studied. The frequency of hypokalemia was 78% (3900 patients). Relating the serum potassium level with the severity of hepatic encephalopathy, 1200 (60%) out of 2000 patients with serum potassium below 2.5 mEq/l were in grade 4 (40%) and 800 out of 2000 were in grade 3 encephalopathy. On the other hand, only 700 patients (6.4%) out 1100 with serum potassium above 3.4 mEq/l were in grade 4 encephalopathy. Conclusion: Hypokalemia is a frequent finding in patients with hepatic encephalopathy and found to be directly related to its severity.
Background The combination of endoscopic band ligation and beta-blockers is the standard of care treatment for secondary prevention of variceal bleeding; however, rebleeding still occurs with associated high mortality. Simvastatin (a lipid-lowering agent) was found to reduce portal hypertension and decrease hepatic fibrosis. This study aimed to assess the effect of adding simvastatin to the standard therapy to prevent variceal rebleeding and its impact on survival in patients with liver cirrhosis. Results This single-center randomized controlled clinical trial included 80 patients with cirrhosis receiving the standard secondary prophylaxis for variceal bleeding composed of endoscopic variceal ligation and non-selective β-blockers (either propranolol or carvedilol). Two weeks after the first attack of hematemesis, patients were randomized into two groups: group I who received the standard therapy (40 patients) and group II who administered simvastatin (20 mg daily for 2 weeks and 40 mg daily after that). Patients were followed up for 1 year. The primary endpoints were rebleeding and overall survival. Thirty patients of group I completed the study while ten patients died during the follow-up period. The simvastatin group showed a significantly better overall 1-year survival (3 deaths during follow-up) compared to the control group (37/40, 92.5% vs. 30/40; 75%) (p-value 0.034); however, this was lacking in Child C patients. No similar difference was present in rebleeding rates between the two groups (5/40, 12.5% vs. 3/40, 7.5%) (p-value 0.456) in groups I and II, respectively. Conclusions Adding simvastatin to the standard therapy in secondary prevention of variceal bleeding could be associated with survival benefits in patients with Child A and B cirrhosis, while was incapable of reducing rebleeding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
