The objective of this study was to compare the performance of the NucliSENS EasyQ HIV-1 v1.2 platform (bioMérieux, France) to the Amplicor HIV-1 DNA test v1.5 (Roche Molecular Systems, Switzerland) in detecting HIV-1 infection in infants using venipuncture-derived whole blood in tubes and dried blood spots. A total of 149 dried blood spots and 43 EDTA-anticoagulated peripheral blood samples were collected throughout Dakar and other areas in Senegal from infants and children aged 3 weeks to 24 months who were born to HIV-1-infected mothers. Samples were tested using the NucliSENS and Amplicor technologies. The NucliSENS and Amplicor results were 100% concordant using either EDTA-anticoagulated peripheral blood or dried blood spots. Compared to Amplicor, the sensitivity and specificity of the NucliSENS test were 100%. The NucliSENS EasyQ HIV-1 RNA assay performed as well as the Amplicor HIV-1 DNA test in detecting HIV-1 infection in infants. In addition, this platform can give an indication of the viral load baseline. The NucliSENS EasyQ platform is a good alternative for early infant diagnosis of HIV-1 infection. 相似文献

Background and methodology
The delay in the diagnosis of HIV infection is a major obstacle to optimal care for this disease. To deal with this problem, we conducted this study among newly diagnosed HIV patients hospitalized in the Fann University Hospital Infectious Diseases Clinic in Dakar. The epidemiological, clinical, biological and outcome aspects are described and patient history reviewed. A qualitative socio-anthropological study was made to understand and describe the logic of the decision processes in the patient's search for treatment.Results
One hundred patients were included, with a mean age of 39.5 ± 11.1 years and a sex-ratio: 1.08. The transmission was mainly heterosexual (90%), and chronic diarrhea (64%) and/or chronic cough (66%) were the principal symptoms leading to diagnosis. The mean delay before diagnosis was 5 ± 4.27 months. The major opportunistic diseases were tuberculosis (44 cases) and infectious diarrhea (23 cases). Most patients were diagnosed at the AIDS stage (97%) and the death rate was 30% among hospitalized patients after admission. Sixty-eight percent of patients had consulted at least three times, generally a “traditional practitioner”, at first and 43% had been hospitalized at least once. The qualitative investigation revealed that the “representation” or the “feeling of severity” of the disease were the principal justifications for consulting the “traditional practitioner” or the physician, respectively.Conclusion
Better information for health workers and global population is necessary for an earlier diagnosis of HIV infection in Dakar. 相似文献65.

Epilepsy is a significant health public problem in Senegal with an estimated prevalence of 8 to 14%. The aim of this study was to determine the clinical and electroencephalographic features of epilepsy in a cohort of Senegalese infants, search for etiological factors and determine the impact of disease on school life. This retrospective study concerned 459 children who attended the neurological outpatients clinic at the Fann hospital, Dakar, Senegal, between July 2003 and December 2006. All were aged under 19 years. Among the 135 children with idiopathic epilepsy, 23.7% had parental consanguinity and 37.77 % familial epilepsy. Rolandic epilepsy and epilepsy with absences were more frequent but several infants with idiopathic epilepsy were not classified. Non-idiopathic epilepsy was noted in 312 children. In this group, estimates of parental consanguinity and familial epilepsy were of 21.79 and 17.94%, respectively. Etiological factors were predominantly pregnancy and birth abnormalities (28.84%) and central nervous system infection (20.19%). Twelve children had febrile seizures. Of patients with idiopathic epilepsy, 65.18% were attending school versus only 9.29 with non-idiopathic epilepsy. 相似文献

We reported in this study a treatment results about 36 Africans patients with follicular lymphoma. The average age of patients was 18 to 73 years old with a median age at 50.83 years old and a sex ratio of 1. Clinical characteristics of patients are mainly represented by advance stage with 70% of stage III and IV of Ann Arbor classification. Histological, we mainly notified follicular lymphoma constituted of small cells 50%, followed by mixed follicular and large cells lymphomas with respectively 27.78 and 22.22%. Using varieties of therapeutics regiments, we obtained 41.67% of complete remission. There were significant correlations between complete remission and histology subtypes. Indeed, the follicular lymphomas constituted by large cells and mixed cells had higher rate of complete remission with respectively 46.67% and 40% in relation with those of small cells with a higher failure rate. Median follow-up was 24 months, the estimated 5-years overall survival and event-free survival were 22%. After a long period, 25 cases of death have been reported, 5 cases of losing sight and 6 patients are still alive and following treatment. Our results are lowers than the reported case in developing country. This none satisfying was in relation with the lower socio-economical level of the main part of the patients. The short survival delay time of our patients didn't permit time to observe transformation case in diffuse large cell lymphomas. 相似文献

We interviewed 108 sickle cell anaemia patients aged 5 years older on priapism, and 113 healthy subjects in a control group. They were recruited in the out-patient consultation of the two sickle cell anemia care units of the Fann teaching hospital in Dakar. Ten cases of priapism were identified, all in the group of sickle cell patients (the difference is significant, p = 0.004). Prevalence of priapism was 9.3%. Actuarial probability of having priapism was 8.3% by 10 years of age, and 38.9% +/- 5.7 by 20 years of age. Before the interview, only 10.2% of the sickle cell patients and 8% in the control group knew about priapism, and most of them were unaware of its association with sickle cell disease (75% of sickle cell anaemia patients and 80% of control subjects). This lack of information should be improved by an educational program. 相似文献

OBJECTIVE: The aim of this article was to describe the epidemiological and clinical aspects of HIV-2 infection in Dakar. DESIGN AND METHODS: This retrospective study was made on 217 HIV-2 infected patients hospitalized between 1986 and 2003; the epidemiological, clinical, and paraclinical data was collected and analyzed using the Epi-Info software version 6.04. RESULTS: The mean age was 40 years+/-9.6 and the male to female sex ratio was 1.33. The mode of transmission was primarily heterosexual. Some risk factors (travel abroad, heterosexual multi-partners, and unprotected sexual intercourse) were more frequently observed in men while others (blood transfusion, HIV positive partners) were noted among HIV-2 infected women. The most frequent symptoms were weight loss (88%), diarrhea (77%), fever (72.4%), asthenia (70.5%), chronic cough, and dermatosis (50.7%). The main opportunistic infections were oral candidiasis (61.8%), tuberculosis (26.3%), intestinal parasitosis (20.3%). The lethality rate was 33.2% and it was correlated with a low CD4 rate. Meningoencephalitis and bacterial infections were associated with a high lethality rate. CONCLUSIONS: The epidemiological and clinical aspects of HIV-2 infection were the same as in HIV-1 infected patients. However the lethality rate remained high among patients hospitalized with a low CD4 cell count. Early HIV testing and improving the diagnostic approach for opportunistic infections remains a high priority. 相似文献

A group of 110 individuals with Schistosoma mansoni infection was investigated. Patients were allocated to one of three treatment groups and given artesunate or praziquantel alone or both in combination. Combined artesunate-praziquantel significantly increased the number of individuals cured at 5 weeks post-treatment, but at 12 weeks was only better than artesunate alone and at 24 weeks there was no statistically significant difference between the three groups. Egg count reduction rate was similar to the rate obtained with praziquantel used alone. 相似文献
