[Mortality pattern in children aged 3-59 months hospitalized in the Intensive Care Unit at a Paediatric Center in Yaounde-Cameroon]. / Profil des décès survenus chez les enfants âgés de 3 à 59 mois dans l'unité des soins intensifs d'un centre pédiatrique à Yaoundé-Cameroun.

INTRODUCTION: mortality risk is high at the Intensive Care Units (ICU) in developing countries. We here report the deaths occurred in the ICU at the Mother and Child Center in Yaounde, Cameroon. METHODS: we conducted a retrospective study on the clinical, socio-demographic features, the therapeutic strategy as well as some of the factors associated with deaths occurred in 200 patients aged 3-59 months between 2010 and 2014. RESULTS: out of 2675 patients included in the study, 1807 were aged 3-59 months and 303 died. The overall and cause-specific mortality rate in this age group was 11.3% and 16.7% respectively. Most patients (152/200; 76.0%) died within 24 months and the median admission time was 7 days. More than half of patients (57.0%) presented to a health center and only 66 (33.0%) presented to a referral hospital. Severe malaria (41.5%), pneumonia (22.7%) and gastroenteritis (27.8%) were the most common diseases. Malnutrition and HIV/AIDS were the underlying causes of death in 23.0% and 20.5% of patients respectively. Gastroenteritis multiplied the risk of death of approximately 6 times (OR = 5.76; p = 0.000) in patients affected by malnutrition and HIV infection. Deaths mainly occurred (90.0%) within 72 hours of admission. CONCLUSION: despite limited resources, some diseases could have been easily treated avoiding complications which require reanimation. It is essential to intensify the fight against malaria, HIV infection and malnutrition.

Risks associated with mother-to-child transmission of HIV infection.

Nguefack F, Koki-Ndombo P, Ngoh R, Soh Fru F, Kinkela MN, Chiabi A. Risks associated with mother-to-child transmission of HIV infection. Turk J Pediatr 2017; 59: 426-433. Early infant diagnosis (EID) permits the detection of Human Immunodeficiency Virus (HIV) infection in exposed children from 4-6 weeks by polymerase chain reaction (PCR). The aim of this study was to assess some maternal and infant characteristics associated with HIV infected children in an EID program. A retrospective study was performed using records of HIV exposed children enrolled in the EID program from 2009 to 2013. Patients recruited were from various health structures and at different clinical stages; some for the Prevention of Mother-to-Child Transmission (PMTCT) follow up, others with signs of HIV infection. Data was collected from completed hospital records of children aged 6 weeks to 18 months containing at least two PCR, one PCR and one serologic test, or one PCR test and viral load. HIV infection was considered if one of the of tests was positive. In all, 130 (5.3%) exposed children with only one positive PCR test, and 1,442 (59%) others with information lacking in their record were excluded. A total 107 out of 871 infants enrolled (12.2%) were infected. Only, 32.7% of the mothers were on antiretroviral therapy (ART). Of these, 53.3% had their first PCR performed between 6 weeks and 6 months. Children were less likely to be HIV infected when their mothers received antiretroviral (ARV) (OR=0.15, 95% CI 0.07-0.30, P=0.000). Factors associated with HIV infection in the children were the lack of ARV prophylaxis (OR=2.07, 95%CI 1.05-4.09, P=0.035) and having mixed feeding (OR=3.91, 95% CI 1.66-9.24, P=0.002) in multivariate analysis. The high rate of infection associated with the maternal and infant correlates of HIV infected children would result from the poor implementation of the PMTCT. Systematic screening of pregnant and breastfeeding women should be reinforced and the lifelong ARVs for PMTCT (Option B+) be promoted.

Obstetrical, maternal characteristics and outcome of HIV-infected rapid progressor infants at Yaounde: a retrospective study.

BACKGROUND: Rapid progressors are exposed to HIV infection at an early stage of life, and the prognosis is poor without treatment. Reducing the proportion of infants who are rapid progressors, require strengthening strategies to achieve the highest level of performance for the PMTCT program. METHODS: This was a retrospective study carried out on HIV infected infants aged less than 12 months, clinically classified stage 4 (WHO) or having CD4 count <25%. We described maternal and obstetrical characteristics of HIV-infected rapid progressors using univariate and bivariate analysis. Patients' survival was monitored from the inclusion time to the end of the study. We then estimated their probability of survival with or without anti-retroviral (ARV) treatment from birth using the Kaplan-Meier method. RESULTS: The characteristics of the mothers of the 150 rapid progressors infants we included were: low level of education (OR=3.87; P=0.016), CD4 count less than 200/mm(3) (OR=43.3; P=0.000), absence of ARV prophylaxis (OR=6.02; P=0.043), or treatment with HAART (OR=5.74; P=0.000) during pregnancy. In the children, the most important findings were lack of co-trimoxazole prophylaxis (OR=11.61; P=0.000) and antiretroviral prophylaxis (OR=2.70; P=0.0344). The survival rate was 84.3% in infants who were receiving HAART as opposed to 43.3% in those who were not (P<0.05). CONCLUSIONS: HIV infected women who are eligible should start antiretroviral treatment prior to a pregnancy, in order to improve their immunological status. This measure associated to cotrimoxazole prophylaxis and ART could improve their survival.
