Voluntary Counseling and Testing for HIV in Rural Area of Democratic Republic of the Congo: Knowledge, Attitude, and Practice Survey among Service Users.

Aims. To determine the prevalence of HIV, the level of sexual risk for HIV, and determinants of VCT attendance among adult population living in a rural area. Methods. A cross-sectional study was conducted in Mbanza-Ngungu, Democratic Republic of the Congo. An anonymous questionnaire was designed to extract relevant data. Results. In our cohort, 69% were respondents of more than 24 years of age and the single marital status was most represented (64.1%). A high proportion of respondents (90.6%) visited VCT service for requiring information (good acceptability). Positive test for HIV was reported in 9.4% of respondents. In this cohort, 49.6% of respondents had declared themselves to never use condom. In binary analysis, there was association between positive HIV test and age (p = 0.04) and religions (p = 0.02). In this cohort, it was observed that positive HIV test was significantly associated with confidentiality (p = 0.02). However, there was no association between positive HIV test and condom use (p = 0.25), knowledge of VCT (p = 0.81), service requested (p = 0.20), and previous HIV test (p = 0.68). Conclusions. Preventive information for AIDS should be recommended in the population living in rural zone.

Cryptosporidium identification in HIV-Infected Humans. Experience from Kinshasa, the Democratic Republic of Congo.

Cryptosporidium is an important protozoan parasite affecting HIV/AIDS patients. To determine the prevalence and the species of Cryptosporidium spp by developing a rapid and efficient real-time PCR-RFLP test. A cross-sectional study was conducted among HIV-infected adults from Kinshasa, the Democratic Republic of Congo. Stool specimens were examined by microscopic evaluation and real-time PCR-RFLP. Out of 242 HIV-infected adults, 10 (4.1%) cases of Cryptosporidium were identified by microscopic examination. Using PCR-RFLP, the prevalence of Cryptosporidium spp was 5.4% (n = 13). All the 13 cases of Cryptosporidium spp had the stage of AIDS of HIV infection. Extracted DNA was amplified by nested PCR targeting a 1030-bp fragment of the 18s RNA gene. RFLP analysis identified one C. parvum, four C. hominis and one non determined Cryptosporidium. The capacity to detect C. parvum, C. hominis and non-determined Cryptosporidium was present among our HIV-infected patients.

Simple markers for the detection of severe immunosuppression in children with HIV infection in highly resource-scarce settings: experience from the Democratic Republic of Congo.

OBJECTIVES: The decision to initiate the antiretroviral therapy in HIV-infected children living in poor countries is compromised by lack of resources. The objective of this study is to identify simple clinical and biological markers other than CD4+ count and viral load measurement that could help the decision to introduce antiretroviral treatment and to monitor patients. METHODS: A cross sectional study was conducted between January and March 2005 in Kinshasa, Democratic Republic of Congo. RESULTS: Eighty-four children infected with HIV were recruited. In this cohort, the lymphocytes (P = 0.001) and CD4 (P = 0.0001) were significantly lower in children with immunological stage 3 and viral load (P = 0.027) was significantly higher in children at the same immunological stage. Reticulocytes (r = +0.440), white blood cells count (r = +0.560), total lymphocytes (r = +0.675) and albumin (r = +0.381) showed positive significant correlations with CD4. Haemoglobin (r = - 0.372), Haematocrit (r = - 0.248), red blood cells (r = - 0.278) and CD4 (r = - 0.285) showed negative significant correlations with viral load. Neutropaenia (P = 0.02), enlarged nodes (P = 0.005) and oral candidiasis (P = 0.04) were associated with viral load >10,000 copies/ml. Oral candidiasis (P = 0.02) was associated with CD4 level < 15%. CONCLUSION: Oral candidiasis, enlarged nodes, total lymphocytes count, neutropaenia and albumin predict severe immunodepression. These clinical and biological markers may guide the clinician in making the decision to initiate antiretroviral therapy in highly resource-scarce settings.

Severe malaria in children: A descriptive report from Kinshasa, the Democratic Republic of Congo.

The decline of susceptibility of Plasmodium falciparum to chloroquine and sulfadoxine-pyrimethamine resulted in the change of drug policy. This policy has probably changed the facies of the severe form of malaria. A prospective study was conducted in Kinshasa, the Democratic Republic of Congo. Data on children aged ≤13 years, diagnosed with severe malaria were analyzed. In total, 378 children were included with an overall median age of 8 years (age range: 1-13 years). Dark urine was seen in 25.1% of cases. Metabolic acidosis (85.2%), hypoglycemia (62.2%) and hemoglobin ≤5 g/dl (39.1%) were the common laboratories features. Severe malaria anemia, cerebral malaria and Blackwater fever (BWF) were found in 39.1, 30.1 and 25.4%, respectively. Mortality rate was 4%. BWF emerges as a frequent form of severe malaria in our midst. Availing artemisin-based combination treatments in the health care system is a priority to reduce the incidence of BWF in our environment.

Interactions between malaria and HIV infections in pregnant women: a first report of the magnitude, clinical and laboratory features, and predictive factors in Kinshasa, the Democratic Republic of Congo.

BACKGROUND: HIV and malaria are among the leading causes of morbidity and mortality during pregnancy in Africa. However, data from Congolese pregnant women are lacking. The aim of the study was to determine the magnitude, predictive factors, clinical, biologic and anthropometric consequences of malaria infection, HIV infection, and interactions between malaria and HIV infections in pregnant women. METHODS: A cross-sectional study was conducted among pregnant women admitted and followed up at Camp Kokolo Military Hospital from 2009 to 2012 in Kinshasa, the Democratic Republic of Congo. Differences in means between malaria-positive and malaria-negative cases or between HIV-positive and HIV-negative cases were compared using the Student's t-test or a non-parametric test, if appropriate. Categorical variables were compared using the Chi-square or Fisher's exact test, if appropriate. Backward multivariable analysis was used to evaluate the potential risk factors of malaria and HIV infections. The odds ratios with their 95% confidence interval (95% CI) were estimated to measure the strengths of the associations. Analyses resulting in values of P < 0.05 were considered significant. RESULTS: A malaria infection was detected in 246/332 (74.1%) pregnant women, and 31.9% were anaemic. Overall, 7.5% (25/332) of mothers were infected by HIV, with a median CD4 count of 375 (191; 669) cells/µL. The mean (±SD) birth weight was 2,613 ± 227 g, with 35.7% of newborns weighing less than 2,500 g (low birth weight). Low birth weight, parity and occupation were significantly different between malaria-infected and uninfected women in adjusted models. However, fever, anemia, placenta previa, marital status and district of residence were significantly associated to HIV infection. CONCLUSION: The prevalence of malaria infection was high in pregnant women attending the antenatal facilities or hospitalized and increased when associated with HIV infection.

Human rabies: a descriptive observation of 21 children in Kinshasa, the Democratic Republic of Congo.

OBJECTIVES: Human rabies has recently emerged as a significant public health threat in Kinshasa, Democratic Republic of Congo (DRC). However, there is little epidemiological information on human rabies especially in children. METHODS: We performed at Pediatrics Department of General Reference hospital of Kinshasa between December 2008 and July 2009, a retrospective study to assess the incidence and to describe their clinical aspects and outcome. RESULTS: A total of 21 cases were observed, rather three cases per month. There were 12 boys (57·1%) and 9 girls (42·9%). Biting animal was found to be dog in all cases (100%). The dog was not immunized in all of cases. On admission, all patients (100%) showed furious rabies manifestations. Only two (9·5%) had their wounds treated and received an anti-rabies vaccine (ARV) after the bite incident. Two (9·5%) patients received rabies immunoglobulin (RIG). The case-fatality rate was 100%. CONCLUSIONS: The disease emerges as a new major public health problem because of a lack of knowledge regarding rabies risk, the poor management of dog bites. Preventative vaccination for rabies should be recommended in the population of Kinshasa, area at high risk to contract rabies, particularly in children.

Nocturnal enuresis in children in Kinshasa, Democratic Republic of Congo.

AIM: To determine the prevalence of nocturnal enuresis in children of Kinshasa in Democratic Republic of Congo. METHODS: In all, 506 questionnaires were sent to parents of children aged 6-12 years randomly selected from four primary schools in Kinshasa, Democratic Republic of Congo. The questionnaire was designed to collect information about prevalence and factors associated with nocturnal enuresis. RESULTS: A total of 415 (82.0%) were correctly completed. In this series, 109 children were identified as nocturnal enuresis in which 50 boys and 56 girls (p > 0.05). Factors associated with nocturnal enuresis were deep sleep, young age and familial history of enuresis (p < 0.05). Only 11% of patients have been consulted by doctors. Twelve children (11.0%) were treated by healers traditional. In the other part, 43 children (39.4%) were frequently punished by their parents. The common self-help strategies were 79 children (72.5%) were submitted to fluid restrictions before going to sleep and 68 (62.4%) were waking the child at night to void. CONCLUSION: In Kinshasa, the prevalence of nocturnal enuresis was high to those reported in Asian and Western countries. Nocturnal enuresis remains an important clinical problem in children but only a small percentage of parents seek medical help.
