[Occurrence of extracapillary glomerulonephritis during Mediterranean boutonneuse fever]

Boutonneuse spotted fever is a summer and late spring infection caused by Rickettsia Conorii mainly in Middle East countries adjacent to the mediterranean coast (1). Malignant forms have been described in debilitated patients associated with prerenal azotemia, acute tubular necrosis or renal vasculitis (2, 3). We report for the first time to our knowledge, the association of an extracapillary glomerulonephritis with a Boutonneuse spotted fever. This observation suggest that Rickettsia Conorii, as other bacteria, could participate to the development of glomerulonephritis.
