Abstrakt: Aim: To describe the diverse clinical and laboratory manifestations of scrub typhus diagnosed in Pondicherry Institute of Medical Sciences, Pondicherry.
Materials and Methods: All cases of febrile illness diagnosed as scrub typhus over a period of 2 years were analysed. Diagnosis was based on the presence of the eschar and/or positive Weil Felix test with a titre of > 1:80.
Results: Fifty cases of scrub typhus were seen over a period of 2 years (April 2006 and April 2008). Common symptoms were high grade fever of 7-14 days duration, nausea, vomiting, headache, myalgia, cough and breathlessness. Eschar was seen in 23 cases (46%) and the common sites were axilla, breast and groin. Weil Felix test was positive in 39 cases (78%). Liver enzymes were elevated in nearly all cases (95.9%). Multiple Organ Dysfunction Syndrome (MODS) was present in one third of our patients (17 out of 50, 34%). Hypotension (8 patients, 16%), renal impairment (6 patients, 12%), ARDS (4 patients, 8%) and meningitis (7 patients, 14%) were some of the important complications. There was a dramatic response to doxycycline in nearly all the patients.
Conclusion: Scrub typhus has emerged as an important cause of febrile illness in Pondicherry. Empirical treatment with doxycycline is justified in endemic areas.
