The spectrum of clinical severity for scrub typhus ranges from inappar
ent, mild, to severe or fatal. The pathologic changes are focal or dis
seminated multiorgan vasculitis of the small blood vessels, a fact tha
t helps explain the great diversity of clinical manifestations that ca
n be encountered. We reported a case of scrub typhus with unusual and
serious multiorgan involvement, including tubulointerstitial nephritis
(TIN) with acute renal failure (ARF), interstitial pneumonitis with a
dult respirator distress syndrome (ARDS), disseminated intravascular c
oagulation (DIC), liver function impairment, upper gastrointestinal bl
eeding, prolonged hyperamylasaemia and hyperlipasaemia. Chloramphenico
l administration rapidly altered the clinical course, but with sequela
e of renal impairment and prolonged hyperamylasaemia and hyperlipasaem
ia for 10 months.
