BACKGROUND: Hepatic transaminase (HT) elevation is frequently seen in children with scrub typhus (ST), but the clinical implication of this common finding is not known.
OBJECTIVE: To describe the clinical profile and outcome of pediatric ST with elevated hepatic transaminase.
METHODS: In this prospective cohort study, all children < 12 years of age presenting with fever for ≥ 5 days and positive immunoglobulin M (IgM) serology for ST were included. Clinical findings, laboratory features and outcomes of children with elevated HT were compared with those who had normal HT.
RESULTS: Of 560 ST positive children included, 257 (45.8%) had associated HT elevation. The common age group affected was 5 to 12 years of age (54.9%). Most of the children came during the second week of fever (68.5%) with mean duration of fever of 9.1 days. The common initial presenting symptoms were cough (77.8%), vomiting (65%) and myalgia (59.1%) and signs were hepatomegaly (64.2%), splenomegaly (57.6%) and generalized lymphadenopathy (54.1%). Eschar was seen in 49.8% of children. Thrombocytopenia (58%) and anemia (49%) were the frequently seen laboratory abnormalities. Severe forms of ST were seen in 45.5% children, of which pneumonia was most common. The fever clearance time (48 ± 19.2 h) and mean duration of hospital stay (6.7 ± 3.3 days) were prolonged in these children. On logistic regression analysis, generalized lymphadenopathy (p = 0.002), ascites (p = 0.037), thrombocytopenia (p < 0.001) and hypoalbuminemia (p = 0.023) were found to be associated with HT elevation in these children.
CONCLUSIONS: Hepatic transaminase (HT) levels increase with the duration of untreated fever and is found to be associated with severe forms of scrub typhus. Children with elevated HT have delay in fever defervescence and their duration of hospital stay was prolonged.
