OBJECTIVE
To document the epidemiological, clinical and laboratory profile of all children with scrub typhus at a tertiary care centre in Chennai between September 2010 and June 2011.
METHODS
The case records of all children admitted and diagnosed with scrub typhus between September 2010 and June 2011 were analysed to look for salient clinical and laboratory parameters.
RESULTS
During the study period, 52 children were admitted with scrub typhus in the authors' hospital. The presenting complaints included fever in all cases. Other symptoms included swelling of legs (50 %) and vomiting (45 %). 13 % presented with CNS symptoms. The commonest physical findings included eschar (67 %), hepatomegaly (94 %), splenomegaly (73 %) and third spacing (67 %). Salient lab parameters included packed cell volume (PCV) <30 (48 %), leucocytosis (56 %), positive C-reactive protein (CRP) (92 %), hypoalbuminemia (79 %). Common complications included acute kidney injury (10 %) and peripheral gangrene (4 %). There was no mortality in the present case series.
CONCLUSIONS
The clinical profile of children with scrub typhus in a tertiary care centre is reported. Eschar and hepatosplenomegaly with a high CRP value is helpful in diagnosis. All patients responded well to the treatment.
