Scrub Typhus in Paediatric Age Group at a Tertiary Care Centre of Eastern India: Clinical, Biochemical Profile and Complications.

BACKGROUND

Scrub typhus is a reemerging zoonosis, which presents as acute febrile illness. Very few paediatric prospective studies on this disease are reported from Eastern India. This prospective observational study was carried out to study the clinical presentation, diagnosis, complications and immediate outcome of Scrub typhus in paediatric population in a tertiary care hospital from Eastern India.

MATERIAL AND

METHODS

Totally 209 cases between 1 month and 18 years of age were included. Clinical manifestations, laboratory parameters and immediate outcome of all patients were recorded. All the data were collected and plotted in Microsoft Excel master chart. Continuous data were presented as mean ± standard deviation (SD) and categorical data as frequency and percentage. All the data analysis was performed using statistical software IBM Statistical Package for the Social Sciences (SPSS) version 20.0.

RESULTS

Highest number of cases (41.1%) were found between 1 year and 5 years age group. Fever was the presenting complaint in all cases. Other common symptoms were cough (34%), pain abdomen (23.4%), vomiting (23%), seizure (11.5%) and altered sensorium (9.6%). Hepatomegaly was found in 56.5% and splenomegaly in 39.7% cases. Eschar was found in 27.3% cases. C-reactive protein was elevated (>10 mg/L) in 93.3% children. Other complications were pneumonitis (20.6%), meningoencephalitis (12.4%), septic shock (8.6%), acute respiratory distress syndrome (5.7%), myocarditis (4.8%) and acute kidney injury (4.3%). Mortality was low (1%).

CONCLUSION

Scrub typhus is not uncommon in paediatric population and it must be considered as a close differential diagnosis of any acute febrile illness even when classical clinical presentations are not found. Early treatment results in favourable outcome.
