Abstract
Background
Acute hepatitis due to various tropical infections can mimic the clinical picture of acute viral hepatitis(AVH), leading to increased morbidity and mortality. We aimed to identify clinical and laboratory parameters that could help to distinguish acute hepatitis due to tropical infections from AVH.
Methods
We retrospectively analyzed our database of 150 children (107 boys) with AVH and 50 children(34 boys)with acute hepatitis due to tropical infections between January 2013 and March 2023. Clinical features, investigations, complications and outcomes were compared.
Results
Hepatitis A (75%) was the commonest etiology of AVH while enteric fever (34%), dengue (26%), scrub typhus (20%) and leptospirosis (16%) constituted the majority of tropical infections. Persistent fever and skin rashes were found in 88% and 16% of patients respectively in the tropical infection group and none in the AVH group (p < 0.001). On univariate analysis, prodromal symptoms, clinically detectable jaundice, cholestatic pattern, total and direct bilirubin and liver enzymes were significantly higher in AVH while headache, myalgia, leukopoenia, thrombocytopenia, hyponatremia were significantly higher in tropical infections group (all p < 0.05). Multivariate analysis identified thrombocytopenia (Odds ratio [OR] 4.237) as an independent positive predictive factor and markedly elevated total bilirubin (OR 0.575), direct bilirubin (OR 0.498), aspartate aminotransferase (OR 0.841) and alanine aminotransferase (OR 0.863) as independent negative predictive factors for acute hepatitis due to tropical infections.
Conclusion
High index of suspicion for tropical infections is warranted in patients with persistent fever after the onset of jaundice, especially in the presence of skin rash and thrombocytopenia.
Acute viral hepatitis and acute hepatitis due to tropical infections can have similar clinical and biochemical parameters. Milder degree of jaundice, lower elevation of serum transaminases and thrombocytopenia can be useful predictors for acute hepatitis due to tropical infections.
