Cardiac involvement in a patient with clinical and serological evidence of African tick-bite fever

BMC Infect Dis. 2005 Oct 20:5:90. doi: 10.1186/1471-2334-5-90.

Abstract

Background: Myocarditis and pericarditis are rare complications of rickettsiosis, usually associated with Rickettsia rickettsii and R. conorii. African tick-bite fever (ATBF) is generally considered as a benign disease and no cases of myocardial involvement due to Rickettsia africae, the agent of ATBF, have yet been described.

Case presentation: The patient, that travelled in an endemic area, presented typical inoculation eschars, and a seroconversion against R. africae, was admitted for chest pains and increased cardiac enzymes in the context of an acute myocarditis.

Conclusion: Our findings suggest that ATBF, that usually presents a benign course, may be complicated by an acute myocarditis.
