Liver injury due to dengue viral infection is not uncommon. Acute liver injury is a severe complicating factor in dengue, predisposing to life-threatening hemorrhage, Disseminated Intravascular Coagulation (DIC) and encephalopathy. Therefore we sought to determine the frequency of hepatitis in dengue infection and to compare the outcome (length of stay, in hospital mortality, complications) between patients of Dengue who have mild/moderate (ALT 23-300 IU/L) v/s severe acute hepatitis (ALT > 300 IU/L).

Background and Aims: HDV infection leads to the most aggressive form of human viral hepatitis for which there is no FDA-approved therapy. PEG IFN-lambda-1a (Lambda) has previously demonstrated a good tolerability profile in HBV and HCV patients compared to PEG IFN-alfa. The goal of Phase 2 LIMT-1 trial was to evaluate the safety and efficacy of Lambda monotherapy in patients with HDV. Approach and Results: An open-label study of Lambda 120 or 180 mcg, administered once weekly by subcutaneous injections for 48 weeks, followed by 24 weeks of posttreatment follow-up. Thirty-three patients were allocated to Lambda 180 mcg (n=14) or 120 mcg (n=19). Baseline mean values: HDV RNA 4.1 log10 IU/mL (SD±1.4); ALT 106 IU/L (35–364); and bilirubin 0.5 mg/dL (0.2–1.2). Intention-to-treat rates of virologic response to Lambda 180 mcg and 120 mcg, 24 weeks following treatment cessation were 5 of 14(36%) and 3 of 19 (16%), respectively. The posttreatment response rate of 50% was seen in low BL viral load (≤4 log10) on 180 mcg. Common on-treatment adverse events included flu-like symptoms and elevated transaminase levels. Eight (24%) cases of hyperbilirubinemia with or without liver enzyme elevation, leading to drug discontinuation, were mainly observed in the Pakistani cohort. The clinical course was uneventful, and all responded favorably to dose reduction or discontinuation. Conclusions: Treatment with Lambda in patients with chronic HDV may result in virologic response during and following treatment cessation. Clinical phase 3 development of Lambda for this rare and serious disease is ongoing.

Acute pancreatitis is a common cause of acute abdominal pain and can range from mild oedema to severe necrosis of the pancreas. It has a significant impact on morbidity, mortality and financial burden. The global prevalence of pancreatitis is substantial, with the highest rates observed in central and eastern Europe. Diagnosing acute pancreatitis involves considering clinical symptoms, elevated serum amylase and/or lipase levels, and characteristic imaging findings. The causes of acute pancreatitis include obstructive disorders, such as gallstones and biliary sludge, alcohol consumption, smoking, drug-induced pancreatitis, metabolic disorders, trauma, medical procedures, infections, vascular diseases and autoimmune pancreatitis. Appropriate management of acute pancreatitis involves determining the severity of the condition, providing supportive care, addressing the underlying cause, and preventing complications. Advances in classifying the severity of acute pancreatitis and implementing goal-directed therapy have contributed to a decrease in mortality rates. ---Continue

Background: Cirrhosis produces variety of symptoms which eventually lead to a negative impact on Health Related Quality of Life (HRQOL). The general aim of this study was to evaluate the magnitude of poor HRQOL and to assess factors related with HRQOL in patients with CLD in Pakistan. Findings: This was a cross sectional study conducted in gastroenterology outpatient clinics of Aga Khan University Hospital, Karachi on adult patients with cirrhosis. In this study chronic liver disease questionnaire (CLDQ) was used to assess HRQOL of these patients and CLDQ score was used as an outcome measure to determine factors related with HRQOL. 273 participants were recruited in the study; 155 (57%) were males. Mean age of participants was 49 ± 11 years. The most common cause for cirrhosis was viral infection 247(91.5%). Mean Model for End Stage Liver Disease (MELD) score was 12.6 ± 6.8 and 2/3 of patients 209 (76.6%) had advanced cirrhosis in Child Turcot Pugh (CTP) B or C stage. Poor HRQOL was seen in 187(69%; 95% C.I.: 63%, 74%) of the participants. Mean CLDQ score was 4.36 ±1.1. Amongst all of the domains, fatigue domain had lower CLDQ score. Hemoglobin (β = 0.09 [SE = 0.04]), Albumin (β = 0.32[SE = 0.09]), Diastolic Blood Pressure (DBP) (β = 0.01[0.005) prior history of decompensation (β = 0.98[SE = 0.39] were significant factors associated with HRQOL in patients with liver cirrhosis. Conclusion: Frequency of poor health related quality of life determined by CLDQ score is high in patients with liver cirrhosis. Hemoglobin, serum albumen, prior history of decompensation (like encephalopathy and upper gastro intestinal bleed), are associated with health related quality of life.
