Etiologic Aspects of Epileptic Seizures of Recent Onset in HIV-AIDS Infected Subjects at the Yaounde Central Hospital (Cameroon)
Introduction: Patients infected with HIV usually develop neurological complications. Seizures are amongst clinical manifestation of these neurological complications of HIV infection. We report on 150 HIV positive patients who pre sented with newly onset seizures. Objectives: Our objective was to evaluate the influence of HIV infection on epilepsy and particularly to look for the most common epilepsy induced complications in our context. Methodology: We re cruited all patients infected with HIV and who consulted at the outpatient or admitted in the in the neurology unit of the Yaounde Central Hospital, for seizures from August 1st 2008 to December 31st 2009. All the patients were aged above 18 years, black and of Cameroonian nationality. All those who had a family history of epilepsy, as well as those with a personal history of epilepsy were excluded from the study. Results: During the period of study, we recruited 150 pa tients aged 38.7 ± 9.9 years and with a n M/F sex ratio of 0.76. Generalized seizures were observed in 66% of patients, of whom 58% were HIV 1 positive and an average CD4 count of 65.4 ± 11.7/μl. Cerebral toxoplasmosis was the most common etiology observed in 30% of cases. Discussion: This study being hospital based must have selected the most serious patient with severe immunodeficiency. This can explain why a precise etiology was found in the majority of cases. Modi et al . (1999) found a space occupying lesion in 53%, meningitis in 22% and 25% without identifiable eti ology in black South Africans. Central nervous system tuberculosis was the most frequent cause encountered in 64% of patients with etiologies. Conclusion: Seizure s are one of the principal manifestations of HIV infection or its complica tions. Their prevalence is 9.5% in our study. Cerebral toxoplasmosis is the most frequent etiology in our study, followed by cryptococcal meningitis and tuberculous meningitis .
