[Polyneuropathies in patients treated with HAART in Bobo-Dioulasso hospital, Burkina Faso]. / Les polyneuropathies chez les patients traités par les ARV au CHU de Bobo-Dioulasso, Burkina Faso.

Peripheral neuropathies (PN) represent the most common neurological manifestation in patients with HIV infection. Introduction of highly active antiretroviral therapy (HAART) had a significant impact on the epidemiology of HIV-associated neuropathies even in poor-resources countries. HIV-infected patients were followed up over a 2-years period from January 2002 to December 2003. PN was clinically diagnosed based on abnormalities of ankle reflexes or vibratory perception and if patients described pain, paresthesia or numbness. Electromyography was not performed in this study Among the 133 HIV-infected patients treated with HAART 31 patients (23 females and 8 males) with 38.8 of mean age were followed up for PN. 95.5% among them were HIV1-infected. According to the availability of the antiretroviral therapy, 9 patients were treated with protocol A including lamivudine + stavudine + nevirapine, 12 patients with protocol B including combination of stavudine + lamivudine + efavirenz, and 10 patients with protocol C with other combinations of antiretroviral therapies. Average CD4 cell count was 229.3/microl and 60% of the sample had < 200 CD4 cell counts at the time of diagnosis. PN occurred within 5.6 months from the institution of the HAART and 80% less than 3 months after the beginning of the treatment. Burning feet syndrome was found in 16.1% of the sample. 45.2% of polyneuropathies occurred in late stage of HIV infection (< 200 CD4/microl). The presence of PN was related to decreased CD4 cells counts and neurotoxic antiretroviral therapy Introduction of HAART has modified the course and the prognosis of HIV infection even in poor resources setting. The incidence of toxic neuropathies is increasing with longer patients' life expectancy and represents a major factor in treatment limitation and the neurological side effects of HAART should be well identified by physicians.

[Guillain-Barré syndrome in HIV-infected patients at Bobo-Dioulasso Hospital (Burkina Faso)]. / Syndrome de Guillain-Barré chez les patients infectés par le VIH à Bobo-Dioulasso (Burkina Faso).

Neurological manifestations of human immunodeficiency virus (HIV) infection are frequent and several associated peripheral neuropathies have been recognized. Among them, Guillain-Barré syndrome (GBS) may occur either early or during the course of the illness. We present a prospective study of 32 consecutive cases of GBS managed over a 5-Year period at Bobo-Dioulasso Hospital where HIV prevalence reaches 20.1p.cent. Male gender predominated (24/32). GBS occurred during the dry season for 65.7p.cent of the patients. Prior infections were found in 84.4p.cent. The motor deficit was paraplegia or tetraplegia. Clinically, paraplegia was associated with transient urinary sphincteric involvement in 24 HIV-infected patients and 3 HIV negative patients. Facial nerve paralysis was found in 3 patients. Among the 32 patients with GBS, 27 were tested positive for HIV. Two patients were infected by HIV1 and HIV2. Cerebrospinal fluid examination showed albumin-cell dissociation and elevated albumin level in 75p.cent of the samples. Autonomic neuropathies were seen in 9 HIV-infected patients. The CD4 counts were above 200/mm3 in 10 among 18 HIV-infected patients. The clinical presentations were more severe in HIV-positive patients with a longer duration of symptoms. HIV-infected patients walked unaided within 51.1 days of peak paralysis. No fatal event occurred. This study indicates clearly that GBS in young adults is strongly associated with HIV infection and should be considered as an indicator of HIV infection in Black Africans. In the tropical context GBS should lead to HIV screening.

[Cryptococcal meningitis in HIV-infected patients at Bobo-Dioulasso hospital (Burkina Faso)]. / La cryptococcose neuroméningée au cours de l'infection par le VIH au Centre hospitalier de Bobo-Dioulasso (Burkina Faso).

Cryptococcus neoformans is an important fungal pathogen in immunocompromised patients. A retrospective study was conducted to investigate the occurrence of Cryptococcus neoformans infection in patients admitted to Bobo-Dioulasso Hospital over a 3 year-period. During this period, cryptococcal meningo-encephalitis was diagnosed in 36 individuals. The median age of the patients under study was 34.25 years. There was a male preponderance (24 males/12 females) in our report. Typical presentations were persistent headaches (27 cases/36), neck stiffness (16/36), altered consciousness (14/36), fever (12/36) and convulsions (9/36). Oral candidiasis coexisted with cryptococcal meningitis in 7 patients. HIV serology was positive in all patients. At diagnosis, lymphocytes counts were < 1500/mm3 in 66.66% patients. CSF examination with India ink helped to the diagnosis of cryptococcosis in all cases. Cryptococcus neoformans was associated with Streptococcus pneumoniae in 4 patients. 15/36 patients died within 1 to 29 days after admission. High mortality was related to delayed diagnosis. Cryptococcal meningitis highly contributes to mortality in HIV-infected patients in Burkina Faso and it may occur in patients not severely immunocompromised patients. A need exists to improve strategies for clinical management of AIDS patients in poor African countries.

[New-onset seizures in patients with immunodeficiency virus infection in Bobo-Dioulasso Hospital (Burkina Faso)]. / Crises d'épilepsie d'apparition récente et infection par le VIH au Centre hospitalier de Bobo-Dioulasso (Burkina Faso).

Seizures are common in advanced stages of immunodeficiency virus (HIV) infection. HIV-infected outpatients and inpatients in the national hospital in Bobo-Dioulasso among whom seizures occurred had been recruited over four years. There were mainly male (30/13) with an average age of 35 years with extremes ranging from 22 to 60 years. New-onset generalised seizures occurred in all cases of cryptococcal meningitis or partial motor secondary generalised in 64% among patients with suspected cerebral toxoplasmosis due to the efficiency of the treatment of the antitoxoplasmic proof. Identified causes such as suspected cerebral toxoplasmosis (65%), suspected tuberculous meningitis (7%) as CSF culture is not available, cryptococcal meningitis (16%) were found in this study. In four cases among 43 patients, no identified causes could be determined. CD4 lymphocytes count which was available in 24 patients was under 200/41 in 74% of the cases. This study indicates clearly that seizures in young adults are strongly associated with focal brain lesions and cerebral toxoplasmosis is becoming an important cause of seizure in tropical area. This should imply a screening of toxoplasmosis with new-onset seizure in young people.

[Peripheral neuropathies revealing HIV infection at the Hospital Center of Bobo-Dioulasso (Burkina Faso)]. / Neuropathies périphériques révélatrices de l'infection par le VIH au Centre hospitalier de Bobo-Dioulasso (Burkina Faso).

Several peripheral neuropathies are associated with human immuno-deficiency virus (HIV) infection. In Africa, certain diseases are of particular importance. In the present work, we report peripheral neurological involvement as revealing signs of HIV infection within the internal medicine unit of a large city over a 2-year period. All adult subjects with a positive HIV serology revealed by a peripheral neuropathy observed in the National Hospital Centre of Bobo-Dioulasso over a two-year period (1 January 1999 and 31 December 2000) were included in the study. 46 cases of peripheral neuropathies revealing HIV infection were screened. Peripheral facial paralysis concerned 25 patients, 15 women and 10 men, in the early stages of HIV infection. The average age was 34 years. For 80% of the patients, he CD4 count was over 200. 5/10 cases of polyneuropathy occurred at the early stage of the HIV infection. Herpes zoster occurred in the early stages in 5/7 cases. 3/4 cases of polyradiculopathy occurred at a later stage with CD4 count under 200. Our study indicates clearly that isolated peripheral facial paralysis, sensitive polyneuropathy, herpes zoster and polyradiculopathy in young adults should lead to HIV testing.

[Peritoneal tuberculosis and HIV infection. Reflection apropos of 22 cases at the National Hospital of Bobo Dioulasso]. / Tuberculose péritonéale et infection par le VIH. Réflexion à propos de 22 cas à l'Hôpital national de Bobo Dioulasso.

Peritonitis tuberculosis is still a frequently encountered pathology in our hospital. Since the AIDS pandemic, cases of peritonitis tuberculosis present increasingly atypical characteristics, largely diverging from classical descriptions. The authors report on 22 cases of peritonitis tuberculosis associated with HIV infection. The study was carried out from June 1997 to December 1999 in the National Hospital Centre Souro SANOU of the Bobo Dioulasso internal office. It concerned 10 women and 12 men of a mean age of 37.9 years. The sex-ratio was 1.2 in favour of men. Diagnosis was established by laparoscopy. Peritonitis tuberculosis associated with HIV accounted for 78.5% of peritonitis tuberculosis cases. The clinical picture was dominated by isolated ascite (100%) associated with an oscillating high fever in 68.2% of cases. Negative results for IDR seemed to reflect poor prognosis. Response to treatment was slow but acceptable. The general prognosis was poor with a mortality rate of 18%.

[Diagnostic problems of expansive intracranial process in HIV infected patients of the Bobo-Dioulasso Central Hospital (Burkina Faso)]. / Problèmes diagnostiques des processus expansifs intracrâniens chez les patients infectés par le VIH au Centre hospitalier de Bobo-Dioulasso (Burkina Faso).

In HIV infection, cerebral focal lesions are relatively frequent and raise many kinds of diagnostic problems. In tropical practice, neuroradiology is scarcely available and necropsy is still not developed. Therefore, diagnosis of intracerebral masses among patients is not easily performed. We examined a total of 72 patients who presented over a 3-year period. Patients were allocated to presumed diagnostic categories of toxoplasma encephalitis (TE), primary central nervous system lymphoma (PCNSL) or progressive multifocal leukoencephalopathy (PML), based on clinical and therapeutic criteria. In an internal medicine ward, we examined 72 suspected cases of intracerebral masses in a sample of 43 males (60%) and 29 females (40%). The average age was 38 years with extremes ranging from 21 to 72 years. Because of diagnostic problems, the presumption of a TE has been retained in 54 cases (75% of the sample) owing to the efficiency of the treatment of antitoxoplasmic proof. As for the other intracerebral masses, despite insufficient diagnostic means, the assumption of PCNSL was made for 8 cases and PML for 6 cases on the basis of evolutional criteria. In 4 cases, no diagnosis could be retained because of insufficient diagnostic means and treatment failure. Since brain tomodensitometry and brain biopsy are not available, treatment of toxoplasmosis has to be systematically set up whenever there is a presumption of intracerebral masses among patients with HIV infection. It is only in case of failure of this treatment that other hypotheses can be contemplated, especially as they are not entirely reliable.
