Scrub typhus meningoencephalitis in children: an experience from Eastern India

Scrub typhus meningoencephalitis (STME) is an uncommon but fatal complication of scrub typhus that requires extra diligence in early identification and treatment. The goal of this study was to look at the clinical characteristics, laboratory results, and outcome of STME in children. A retrospective study was conducted in the paediatric intensive care unit of a tertiary care hospital in Eastern India between April 2021 and September 2022. It was carried out in children aged 1 month-12 years. Sixteen children were diagnosed with STME out of 75 acute encephalitis syndrome (AES) cases. The male-to-female ratio was 3:1, with a mean age of 4.28 ± 3.36 years. All the children hailed from rural areas. Fever (100%), convulsions (87.5), altered sensorium (93.75%), nuchal stiffness (25%), vomiting (75%), pallor (75%), and hepatomegaly (50%) were the most prevalent clinical manifestations. The average duration of fever upon presentation was 8.25 ± 2.11 days and the average length of hospital stay was 9.00 ± 4.59 days. The complications encountered were shock (3), interstitial pneumonia (1), myocarditis (1), raised intracranial pressure (1), and right-sided hemiplegia (1). Fifteen children recovered completely, whereas one child suffered from residual right-sided neurodeficit. A high index of suspicion needs to be maintained for STME as a possible AES entity, as anti-scrub measures administered promptly can go a long way in mitigating the related morbidity and mortality especially in resource-constrained settings.
