RESUMO
The aims of this study were to determine the place of malaria at the Infectious Disease Clinic in Dakar, Senegal, to identify diseases associated with malaria, and to assess malaria mortality with or without co-morbidity. The files of all patients hospitalized from 2001 to 2003 in whom at least one test for malaria (thick films/spears) was performed to detect malaria parasites were reviewed. Malaria was diagnosed in patients presenting fever and positive thick films demonstrating asexual blood stages of Plasmodium. Data were collected from hospital charts. A total of 416 patients presented malaria (prevalence rate, 25.9%). The male-to-female sex ratio was 1:7 and mean age was 33 +/- 18 years. Of the 416 patients diagnosed with malaria, 273 (65.6%) presented severe forms. The overall mortality rate of malaria with or without co-morbidity was 25.7% (107/416). There was not a statistically significant difference between mortality due to isolated malaria and malaria associated with tuberculosis (23.4% versus 18.5%) (p = 0.7) or tetanus (23.4% versus 17.6%) (p = 0.34). Conversely mortality of malaria in HIV-positive patients was higher (58% versus 19%) (p = 10(-6)). Thus, malaria is of major concern in our department.
