Abstract

Introduction: 60 percent of hospitalization causes of intravenous drug users are infection,
of which 5 to 15 percent of them due to endocorditis. Infective endocorditis is a common
infection among intravenous drug users and can cause high mortality and morbidity. This
study was conducted to evaluate clinical and para-clinical presentations of drug users.
Methods: In a descriptive study we evaluate 33 narcotic addicts with documented infective
endocarditis in two tertiary care hospitals in Tehran, Iran; Imam Hosein and Loghman
Hakim hospitals during 2002-2008. Demographic information, clinical manifestation,
radiologic, laboratory and echocardiographic data were evaluated. The data were analysed
using SPSS software.
Results: 82% of patients were in 20-40 year old age group. 52% of the cases were referred
to the hospital with main complain of fever and cough and 27% with pain and fever. Fever
was observed in 91% of the patients. Positive blood culture was observed in 9 cases and
negative blood culture in 14 cases. The most common involved valve was tricuspid.
Mortality rate was 45%.
Conclusion: Endocarditis should be considered in intravenous drug users when they
present with fever. Blood culture may be negative due to previous use of antibiotics and
poor technique of culture.
