Introduction: Leptospirosis is an important zoonotic disease commonly found in tropical or sub-tropical countries. The most severe form is Weil's syndrome which presents with jaundice, renal failure, and bleeding diatheses. Although jaundice occurs in 38% of patients with leptospirosis, no studies in Asia have focused on the liver biochemical profile of these patients. Characterization of liver biochemical profile and ultrasonographic findings may shed more light on the disease process. Identification of liver biochemical parameters that portend a poor prognosis may also allow for early aggressive intervention., Objective: To describe the liver biochemical profile and liver ultrasonographic findings in adult patients with laboratory-confirmed leptospirosis, admitted at a tertiary hospital in Manila, Philippines. The association of clinical and laboratory features with clinical outcomes (i.e., severe liver injury, Weil's syndrome, and mortality) was also investigated., Methods: This retrospective cross-sectional study reviewed all available cases of adult patients with laboratory-confirmed leptospirosis admitted in the Philippine General Hospital from January 2009 to August 2018. The clinical features, liver biochemical profiles, and ultrasound findings were recorded and analyzed. Comparison between the means of each group based on clinical outcome (i.e., mortality, Weil's syndrome) was done via Students' t-test for continuous variables, and calculation of the Odds Ratio for categorical variables., Results: Total and direct bilirubin levels were elevated in patients with leptospirosis compared to serum amino-transferases and alkaline phosphatase levels which were only mildly elevated. Abdominal ultrasound showed typically un-enlarged livers with normal parenchymal echogenicity, normal spleens, and non-dilated biliary trees. Dyspnea was associated with an increased odds for mortality. Although jaundice was present in 39.5% of patients and significantly associated with severe liver injury, this was not associated with mortality. Liver biochemical test values did not differ among patients who expired and those who survived to discharge. The presence of myalgia and abdominal pain increased the odds for Weil's syndrome., Conclusion: To date, no local studies have fully described the liver biochemical profile of patients with leptospirosis. Our findings are compatible with previous studies showing that leptospirosis typically presents with predominantly elevated direct bilirubin from cholestasis and systemic infection. Contrary to previous literature, however, our study found no association between jaundice and mortality., Competing Interests: The authors claim no conflict of interest in any form.

Gastric adenocarcinoma presenting as a submucosal tumor (SMT) accounts to only 0.1% to 0.63%. A 56-year-old Filipino male presenting with new onset melena underwent magnifying endoscopy, narrow-band imaging, endoscopic ultrasound, and computed tomography revealing a 2.5 cm x 2.0 cm polypoid SMT-like lesion at the fundus. Total gastrectomy with lymph node dissection and esophagojejunostomy was performed with histopathology showing adenocarcinoma. This suggests the need for different modalities to ensure the accuracy of diagnosis and the need for subsequent invasive treatments., Competing Interests: All authors declared no conflicts of interest., (© 2024 Acta Medica Philippina.)
