Glucose-6-phosphate dehydrogenase (G6PD) deficiency is associated with asymptomatic malaria in a rural community in Burkina Faso

<p><b>OBJECTIVE</b>To investigate 4 combinations of mutations responsible for glucose-6-phosphate dehydrogenase (G6PD) deficiency in a rural community of Burkina Faso, a malaria endemic country.</p><p><b>METHODS</b>Two hundred individuals in a rural community were genotyped for the mutations A376G, G202A, A542T, G680T and T968C using TaqMan single nucleotide polymorphism assays and polymerase chain reaction followed by restriction fragment length polymorphism.</p><p><b>RESULTS</b>The prevalence of the G6PD deficiency was 9.5% in the study population. It was significantly higher in men compared to women (14.3% vs 6.0%, P=0.049). The 202A/376G G6PD A- was the only deficient variant detected. Plasmodium falciparum asymptomatic parasitaemia was significantly higher among the G6PD-non-deficient persons compared to the G6PD-deficient (P<0.001). The asymptomatic parasitaemia was also significantly higher among G6PD non-deficient compared to G6PD-heterozygous females (P<0.001).</p><p><b>CONCLUSIONS</b>This study showed that the G6PD A- variant associated with protection against asymptomatic malaria in Burkina Faso is probably the most common deficient variant.</p>

Efficiency of HAART in the prevention of mother to children HIV-1 transmission at Saint Camille medical centre in Burkina Faso, West Africa

OBJECTIVE@#To evaluate efficiency of HAART in the prevention of mother to child HIV transmission.@*METHODS@#A longitudinal study was conducted on 1 300 women attending the antenatal service at Saint Camille Medical Centre from September 2010 to July 2011. The HIV status of mothers was determined by rapid tests and ELISA. Discordant results were confirmed by real-time PCR. PCR was used to determine HIV status of children born from HIV-positive mothers.@*RESULTS@#Among 1 300 pregnant women tested for HIV, 378 were seropositive. Mothers were predominantly housewives (69.7%), and their mean age was (28.32±0.15) years. The overall prevalence of HIV transmission from mother to child was 4.8% (18/378). This prevalence differed significantly from 0.0% (0/114) to 6.8% (18/264) in children born from mothers under HAART and those with mothers under New Prophylactic Protocol (AZT + 3TC + NVP), respectively (P< 0.01). Children's mortality rate during the medical follow up was 1.3% (5/378). Among 16 women with HIV dubious status by ELISA, the Real Time PCR confirmed 2/16 (12.5%) as HIV positive.@*CONCLUSIONS@#The protocol of prevention of mother to children HIV transmission (PMTCT) is effective. The rate of HIV vertical transmission is significantly reduced. Early diagnosis determined by PCR of children born from HIV-positive mother is necessary and recommended in the context of PMTCT in Burkina Faso. We also found that PCR is an effective tool to confirm HIV status in pregnant women.

Enteric parasites prevalence at Saint Camille Medical Centre in Ouagadougou, Burkina Faso

OBJECTIVE@#To assess the prevalence of parasitic infections among patients attending Saint Camille Medical Centre and to estimate co-parasitic infections rates.@*METHODS@#From January to December 2009, stool samples were collected from 11 728 persons, aged from five months to 72 years and suffering from gastroenteritis. After macroscopic description, the stools were examined by light microscopy to search for the presence of parasites.@*RESULTS@#From the 11 728 analyzed stools, 6 154 (52.47%) were infected with at least one parasite. Protozoan frequently encountered were: Giardia intestinalis (43.47%), Entamoeba histolytica/Entamoeba dispar (30.74%) and Trichomonas intestinalis (21.72%), while Hymenolepis nana (2.25%) was the most common helminth. Co-infections occurred in 22.34% cases. Within the multi-infected samples, dual and triple infections accounted for 71.18% and 20.00%, respectively. Giardia intestinalis for protozoan and Hymenolepis nana for helminths were the most implicated co-infections.@*CONCLUSIONS@#This study confirms that intestinal parasites are still a public health problem in Burkina Faso. To reduce the incidence of parasitic infections, it is necessary to promote the education of people so that they practice the rules of individual and collective hygiene.
