ABSTRACT

BACKGROUND: Spontaneous bacterial peritonitis is a common bacterial infection of ascitic fluid, mainly in ascites due to liver cirrhosis. Mannose-binding lectin (MBL) can activate phagocytosis and the complement system. Spontaneous bacterial peritonitis was detected to be higher in MBL deficiency. This study aimed to assess ascitic fluid MBL in liver cirrhosis and spontaneous bacterial peritonitis. METHODS: Ninety patients with cirrhotic ascites were included. Forty five of them had SBP. Child- Pugh score, Model for End Stage Liver Disease (MELD) and its update (uMELD) scores were used to assess the severity of liver cirrhosis. Ascitic fluid samples were obtained for differentiation of leucocytic count, estimation of albumin, protein, glucose, and serum-ascitic albumin gradient. Ascitic fluid levels of MBL were measured for all patients. SBP was documented if polymorphonuclear leucocytic count ≥250/mm in ascitic fluid. RESULTS: Ascitic fluid MBL level was significantly lower in patients with SBP. MBL had a significant negative correlation with ascitic total leukocytic count (TLC), also with serum creatinine, bilirubin, PT, INR and MELD score among SBP patients. However, it had a significant positive correlation with ascitic protein and with platelets. According to multivariate analysis, fever, TLC, platelets, creatinine, MBL, glucose and polymorphs were independent predictors for SBP development. CONCLUSION: Ascitic fluid MBL could be a good predictive and prognostic marker in patients with cirrhosis and spontaneous bacterial peritonitis.

ABSTRACT

Novel Corona Virus 2019 (COVID-19) is a new virus spread rapidly all over the world. It has specific respiratory or gastrointestinal tract symptoms. Its reported complications include respiratory distress, systemic inflammatory response syndrome, and septic shock. Due to heavy cytokines released by the virus; corticosteroids (40-120 mg / day) were given to severe cases to reduce pneumonia. It's a difficult task to control the spread of SARS-CoV-2, and to invent proper vaccines and treatments. In this review, the existing understanding of fatal, pandemic human coronavirus SARS-Cov2 (COVID-19), with special reference to its diagnosis, origin, transmission, and different approaches to develop its therapeutics, will be discussed.

ABSTRACT

BACKGROUND: HCV treatment showed dramatical change due to the introduction of potent, strong, direct antiviral drugs. Before the appearance of Direct-acting antivirals, multiple therapeutic interventions were used for hepatitis C, but none of these interventions were effective on patient-centered outcomes. Direct-acting antivirals cause disruption of viral replication because they target specific nonstructural viral proteins. AIM: To review the advantages of efficient HCV therapy and its long term drawbacks. METHODS: A search of the literature published in indexed databases (PubMed, Medline In-Process, and Embase) within the last 5 years was conducted. Any duplicated citations were excluded before first-pass screening. Citations (titles and abstracts) were screened for eligibility by a single reviewer. Full texts (including congress abstracts, posters and other congress communications) of citations deemed relevant during title and abstract screening were retrieved for second-pass review. RESULTS: Studies on the clinical effects of DAAs for hepatitis C show better tolerance, improved survival and fewer complications when compared to previous interferon therapy. CONCLUSION: HCV treatment has improved dramatically. Since that time, there are multiple approved oral therapies all with high efficacy. The most important factor which should be considered during choosing appropriate therapy is to ensure that it covers the viral genotype of the infected patients.

ABSTRACT

Spontaneous bacterial peritonitis (SBP) is a severe complication in cirrhotics with ascites. Monocyte chemotactic protien-1 (MCP-1) is a chemotactic factor for monocytes/macrophages, and it activates lymphocytes and neutrophils during infection. This study aimed to evaluate the role of MPC-1 in the pathogenesis of SBP and assess its prognostic value and correlation to disease severity. The study included ninety patients with liver cirrhosis and ascites. Patients were divided into 2 groups: Group I including 45 ascetic patients with SBP (polymorph nuclear cell count (PMN) >= 250 cell/mm3 in ascitic fluid), and Group II including 45 ascetic patients without SBP. Assessment of the severity of liver cirrhosis was done using the modified Child-Pugh and model for end stage liver disease (MELD) scores. Ascetic fluid samples were subjected to total leucocytic count and differential, albumin, protein, glucose, and serum-ascetic albumin gradient analysis Ascetic fluid levels of (MCP-1was measured by ELISA. Higher level was detected in patients with SBP as compared to those without SBP. The number of polymorph nuclear cell count (PMN) >= 250 cell/mm3 in ascitic fluid) was used as gold standard for diagnosis of SBP. The diagnosis sensitivity and specificity of MCP level test were 86.7% and 95.4% respectively at cutoff of122.5ng/ml with accuracy 91%. MCP-1 level showed positive significant correlation with TLC, PMN leucocytes and MELD score. In conclusion, ascitic fluid MCP-1 level could be a reliable test for diagnosis of SBP, and could be used as a prognostic marker due to its positive correlation with the severity of liver disease.

ABSTRACT

Hepatitis C virus (HCV) is a global challenge; 130-175 million are chronically infected. Over 350000 die each year from HCV. Chronic HCV is the primary cause of cirrhosis, hepatocellular carcinoma (HCC), and end-stage liver disease. Management of chronic HCV is aimed at preventing cirrhosis, reducing the risk of HCC, and treating extra hepatic complications. New treatments for chronic HCV has been devoted based on direct-acting antivirals, as pegylated interferon (peginterferon) is responsible for many side effects and limits treatment access. Sofosbuvir is the first compound to enter the market with Peginterferon-free combination regimens.
