Abstract

Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. We prospectively studied the clinico-laboratory profile and outcome of 358 children aged 1 day to 18 years diagnosed with scrub typhus from Chennai, South India. All children (100%) had fever. Eschar was seen in 67%. All children were treated with oral doxycycline and those with complications were treated with intravenous chloramphenicol/azithromycin. Rapid defervescence (within 48 h) after initiation of doxycline was seen in 306 (85%) and 52 (14.5%) developed complications. Multivariate logistic regression analysis revealed that children who had an elevated aspartate amino transferase (> 120 IU/L) and the presence of thrombocytopenia (platelet count less than 1 lac cells/mm3) at admission had high risk of developing complications. The overall mortality rate in this series was 0.8%.

Conclusion: Our 4-year study highlights the clinico-laboratory profile of Scrub typhus in children from Chennai, South India. Early recognition and prompt treatment reduces the complication and mortality.

What is Known:

• Scrub typhus is endemic to tsutsugamushi triangle, a geographical triangle extending from northern Japan in the east to Pakistan and Afghanistan in the west and northern Australia in the south.

• There is paucity of data regarding its clinico-laboratory profile in neonates as well as its predictors of outcome.

What is New:

• Children who had an elevated AST and the presence of thrombocytopenia at admission had high risk of developing complications.
