Identification of the bacteria and their susceptibility to commonly used antibiotics is very essential for the treatment of the patients. \u0000Aims: This study aims to analyze current trends in bloodstream infection by accessing their bacteriological profile and antibiotic susceptibility. \u0000Methods: This is a hospital-based retrospective analysis of blood cultures of patients suspected with bloodstream infection. We conducted a three years (January 2018 to January 2021) retrospective analysis of blood culture reports from patients suspected with bloodstream infection. Data of the laboratory reports were used to determine bloodstream infection, blood culture contamination, pathogen profile and antimicrobial resistance patterns. \u0000Results: Out of 12811 blood samples that were sent to microbiology laboratory for culture, 438 were positive cultures. The most common etiological agent causing Bloodstream Infection was found to be Salmonella Typhi with129 isolates (29.6%) followed by Escherichia coli (21.9%). There was a significant rise in resistance to most of the frequently used antibiotics. \u0000Conclusion: Salmonella Typhi is the most frequent bacteria to be isolated in Bloodstream Infection. Resistance towards different etiological agents of Bloodstream Infection is alarmingly increasing every year. Resistance to frequently prescribed drugs should be of concern to the clinicians prescribing the drugs.","PeriodicalId":166882,"journal":{"name":"Journal of Nepalgunj Medical College","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121787647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can be a serious abdominal emergency associated with significant morbidity and mortality. Cholelithiasis is most common cause of acute pancreatitis and excessive alcohol consumption is second most frequent cause which together account for approximately 80% of underlying etiology. The detection of biliary etiology is crucial to delivery of definitive therapy to prevent repeated attacks of acute pancreatitis. During an attack of acute pancreatitis, elevation of alanine aminotransferase to >150 IU/L is a predictive factor for biliary cause of acute pancreatitis. \u0000Aims: To investigate the predictive value of raised alanine aminotransferase in determining biliary etiology in patients presenting with acute pancreatitis. \u0000Methods: A prospective study was done among 70 patients who were admitted in surgery department over a period of one year with diagnosis of acute pancreatitis. Peak alanine aminotransferase within 48 hours of presentation was recorded. The diagnosis was based on typical clinical presentation of acute pancreatitis combined with an increase in serum amylase levels ≥ 3 times the upper limit of the laboratory reference value.
