ABSTRACT
Salmonella typhi remains an endemic disease in Madagascar. Acute pancreatitis remains a rare complication of S. typhi colitis. We presented the case of a 27-year-old male, admitted to febrile diarrhea, vomiting, and severe abdominal pain. Blood work-up revealed elevated plasma lipase level. Abdominal CT scan showed acute pancreatitis without necrosis. Blood and stool culture positivity for S. typhi. Patient was diagnosed as acute pancreatitis caused by S. typhi. The outcome was favorable under symptomatic medical treatment (rehydration and analgesic) combined with adapted antibiotic therapy. Acute pancreatitis is a possible complication of Salmonella infections. The presence of severe abdominal pain and febrile diarrhea should draw clinicians' attention to possible Salmonella acute pancreatitis.
ABSTRACT
BACKGROUND: Variceal upper gastrointestinal bleeding is a dreadful complication of portal hypertension with a significant morbidity and mortality. Different prognostic scores can be used. However, in the local context of Madagascar, the completion of paraclinical investigations can be delayed by the limited financial means of patients. Hence, determining clinical mortality risk factors of variceal upper gastrointestinal bleeding could be interesting. The aim of the study was to evaluate the clinical mortality risk factors of variceal gastrointestinal bleeding (VUGIB). METHOD: An observational, cohort retrospective study was conducted over an 8-year period (2010-2017), at the surgical intensive care unit of the J.R. Andrianavalona University Hospital, Antananarivo, in patients admitted for VUGIB confirmed by upper gastrointestinal endoscopy and whose clinical examination was performed at admission. The primary endpoint was intensive care unit (ICU) mortality. Univariate analysis and multivariate logistic regression analysis were performed to identify risk factors for ICU mortality, with OR defining odds ratio. A p value <0.05 was considered significant. RESULTS: 1920 patients were admitted for gastrointestinal bleeding of any digestive causes; the source of bleeding was variceal in 269 patients (14%). The predominantly male population (sex ratio = 2.5), aged 47.1 ± 13.7 years was mostly American Society of Anesthesiologists (ASA) 1 classification (58.4%). In 56.5% of patients, the gastrointestinal bleeding had not occurred before. The mortality rate was 16.0%. Three major clinical factors of mortality were identified: previous endoscopic band variceal ligation (OR = 12.57 [2.18-72.58], p = 0.005), tachycardia >120 bpm (OR = 2.91 [1.04-8.14], p = 0.041), and ascites (OR = 3.80 [1.85-7.81], p < 0.001). CONCLUSION: Upper gastrointestinal bleeding may be life-threatening. The mortality scores are certainly useful; however, the identification of clinical factors is interesting in countries like Madagascar, pending the results of paraclinical investigations.
