Factors affecting uptake of???3 doses of Sulfadoxine-Pyrimethamine for malaria prevention in pregnancy in selected health facilities, Arusha region, Tanzania.

ABSTRACT: BACKGROUND:Tanzania adopted the revised World Health Organization policy in 2013 recommending a minimum of ?3 doses of Intermittent Preventive Treatment during pregnancy with Sulfadoxine-Pyrimethamine (IPTp-SP) to protect against malaria. A study in Tanzania in 2014 reported low (9%) uptake. We investigated health workers knowledge about IPTp-SP and factors that influenced uptake of >?3 doses of IPTp-SP among pregnant women. METHODS:We conducted a cross-sectional study in 2017 among post-delivery women and health care workers from nine randomly-selected public health facilities in three Districts of Arusha Region. Probability proportional to size methodology was used to determine number of participants per facility. We used a structured questionnaire to collect socio-demographic and obstetric data, information on doses of SP received, and knowledge of SP for IPTp. Health care workers were interviewed about their knowledge for IPTp- SP and challenges encountered in its uptake and use. RESULTS:We interviewed 556 persons (median age 26?years, range 16-42?years) with the response rate of 99.3%. Of these, 484 (87.1%) had >?3 Antenatal Care (ANC) visits. A total of 402 (72.3%) were multigravida with 362 (65.1%) having given birth at least once. Of the 556 participants, 219 (39.4%) made their first ANC booking at ?3 doses of SP-IPTp. Factors associated with uptake of >?3 doses of IPTp-SP included having secondary or higher education [Adjusted Odds Ratio (AOR) =1.6, 95%CI 1.1-2.4], attending ?4 ANC visits [AOR?=?3.1, 95%CI 2.1-4.6], having first antenatal booking at ?3 doses of IPTp-SP. That is below the Tanzania national target of 80%. Making >?4 ANC visits, having secondary or higher education, making an early first ANC visit and having adequate knowledge on IPTp-SP promoted uptake of >?3 doses. Further qualitative studies are needed to explore factors that might contribute to low uptake of SP.

Project description:BackgroundBrucellosis is listed as one of six priority zoonoses in Tanzania's One Health strategic plan which highlights gaps in data needed for the surveillance and estimation of human brucellosis burdens. This study collected data on current testing practices and test results for human brucellosis in Arusha region, northern Tanzania.MethodsRetrospective data were extracted from records at 24 health facilities in Arusha region for the period January 2012 to May 2018. Data were captured on: the test reagents used for brucellosis, procurement and testing protocols, the monthly number of patients tested for brucellosis and the monthly number testing positive. Generalised linear mixed models were used to evaluate relationships between health facility characteristics and the probability that brucellosis testing was conducted in a given month, and the proportion of individuals testing positive.ResultsFour febrile Brucella agglutination tests were used widely. The probability of testing for brucellosis in a given month was significantly associated with an interaction between year of testing and facility ownership. Test probability increased over time with more pronounced increases in privately owned as compared to government facilities. The proportion of individuals testing positive for brucellosis was significantly associated with facility type and district, with individuals tested in hospitals in Meru, Monduli and Ngorongoro districts more likely to test positive.ConclusionsFebrile Brucella agglutination tests, known for their poor performance, were the mainstay of brucellosis testing at health facilities in northern Tanzania. The study indicates that historical data on human brucellosis in Arusha and other regions are likely to provide an inaccurate measure of true disease burden due to poor performance of the tests used and variation in testing practices. Measures to address these identified shortcomings could greatly improve quality of testing and surveillance data on brucellosis and ultimately inform prevention and control of this priority disease.

Project description:ObjectivesSulfadoxine-pyrimethamine (SP) is an antimalarial drug that acts on the folate metabolism of the malaria parasite. We investigated whether folate (FA) supplementation in a high or a low dose affects the efficacy of SP for the treatment of uncomplicated malaria in pregnant women.DesignThis was a randomized, placebo-controlled, double-blind trial.SettingThe trial was carried out at three hospitals in western Kenya.ParticipantsThe participants were 488 pregnant women presenting at their first antenatal visit with uncomplicated malaria parasitaemia (density of >or= 500 parasites/microl), a haemoglobin level higher than 7 g/dl, a gestational age between 17 and 34 weeks, and no history of antimalarial or FA use, or sulfa allergy. A total of 415 women completed the study.InterventionsAll participants received SP and iron supplementation. They were randomized to the following arms: FA 5 mg, FA 0.4 mg, or FA placebo. After 14 days, all participants continued with FA 5 mg daily as per national guidelines. Participants were followed at days 2, 3, 7, 14, 21, and 28 or until treatment failure.Outcome measuresThe outcomes were SP failure rate and change in haemoglobin at day 14.ResultsThe proportion of treatment failure at day 14 was 13.9% (19/137) in the placebo group, 14.5% (20/138) in the FA 0.4 mg arm (adjusted hazard ratio [AHR], 1.07; 98.7% confidence interval [CI], 0.48 to 2.37; p = 0.8), and 27.1% (38/140) in the FA 5 mg arm (AHR, 2.19; 98.7% CI, 1.09 to 4.40; p = 0.005). The haemoglobin levels at day 14 were not different relative to placebo (mean difference for FA 5 mg, 0.17 g/dl; 98.7% CI, -0.19 to 0.52; and for FA 0.4 mg, 0.14 g/dl; 98.7% CI, -0.21 to 0.49).ConclusionsConcomitant use of 5 mg FA supplementation compromises the efficacy of SP for the treatment of uncomplicated malaria in pregnant women. Countries that use SP for treatment or prevention of malaria in pregnancy need to evaluate their antenatal policy on timing or dose of FA supplementation.

Project description:BackgroundSulfadoxine-pyrimethamine (SP) is a cornerstone of malaria chemoprophylaxis and is considered for programmes in the Democratic Republic of Congo (DRC). However, SP efficacy is threatened by drug resistance, that is conferred by mutations in the dhfr and dhps genes. The World Health Organization has specified that intermittent preventive treatment for infants (IPTi) with SP should be implemented only if the prevalence of the dhps K540E mutation is under 50%. There are limited current data on the prevalence of resistance-conferring mutations available from Eastern DRC. The current study aimed to address this knowledge gap.MethodsDried blood-spot samples were collected from clinically suspected malaria patients [outpatient department (OPD)] and pregnant women attending antenatal care (ANC) in four sites in North and South Kivu, DRC. Quantitative PCR (qPCR) was performed on samples from individuals with positive and with negative rapid diagnostic test (RDT) results. Dhps K450E and A581G and dhfr I164L were assessed by nested PCR followed by allele-specific primer extension and detection by multiplex bead-based assays.ResultsAcross populations, Plasmodium falciparum parasite prevalence was 47.9% (1160/2421) by RDT and 71.7 (1763/2421) by qPCR. Median parasite density measured by qPCR in RDT-negative qPCR-positive samples was very low with a median of 2.3 parasites/µL (IQR 0.5-25.2). Resistance genotyping was successfully performed in RDT-positive samples and RDT-negative/qPCR-positive samples with success rates of 86.2% (937/1086) and 55.5% (361/651), respectively. The presence of dhps K540E was high across sites (50.3-87.9%), with strong evidence for differences between sites (p?<?0.001). Dhps A581G mutants were less prevalent (12.7-47.2%). The dhfr I164L mutation was found in one sample.ConclusionsThe prevalence of the SP resistance marker dhps K540E exceeds 50% in all four study sites in North and South Kivu, DRC. K540E mutations regularly co-occurred with mutations in dhps A581G but not with the dhfr I164L mutation. The current results do not support implementation of IPTi with SP in the study area.

Project description:Malaria in pregnancy poses a great risk to both mother and fetus. In Ghana, malaria accounts for 3.4% of deaths and 16.8% of all hospital admissions in pregnant women. In 2014, Ghana updated her policy on intermittent preventive treatment of malaria in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) to reflect the updated policy of the WHO. This study determined the level of uptake of sulfadoxine pyrimethamine (SP) to serve as baseline for monitoring progress and also reviewed stock levels of SP, a key factor in the programme implementation.A cross-sectional hospital-based study was carried out among nursing mothers who had delivered within 12 weeks and were seeking postnatal care at Osu Government Maternity Home in Accra. Antenatal record books of the mothers were reviewed and data collected on number of visits and receipt of IPTp-SP. Mothers were interviewed and data collected on their background characteristics and obstetric history. Data on SP stock levels for the past 6 months were also reviewed. Logistic regression analysis was carried out to determine antenatal indicators on uptake of IPTp-SP using Stata version 12.The proportion of uptake of three-five doses of SP were: IPT3 (87.5%), IPT4 (55.7%) and IPT5 (14.5%). The proportion of women who received the first dose of SP at 16 weeks of gestation was 21.3%. Women who made ≥4 visits were more likely to receive ≥3 doses of SP than those who made <4 visits (AOR = 4.57, 95% CI 1.15-18.16, p < 0.05). Women receiving the first dose of SP in the third trimester were less likely to receive ≥3 doses of SP than those who received the drug in the second trimester (AOR = 0.04, 95% CI 0.01-0.16, p < 0.05). Stock levels of SP were adequate to meet the demands by the pregnant women at the Maternity Home for the period under review.The uptake of ≥3 doses of SP was high in the study area. Frequent visits to the antenatal clinic and early uptake of the first dose of SP by pregnant women are necessary to achieve the new target of five or more doses of SP.
