The effect of cotrimoxazole prophylactic treatment on malaria, birth outcomes, and postpartum CD4 count in HIV-infected women.

BACKGROUND: Limited data exist on cotrimoxazole prophylactic treatment (CPT) in pregnant women, including protection against malaria versus standard intermittent preventive therapy with sulfadoxine-pyrimethamine (IPTp). METHODS: Using observational data we examined the effect of CPT in HIV-infected pregnant women on malaria during pregnancy, low birth weight and preterm birth using proportional hazards, logistic, and log binomial regression, respectively. We used linear regression to assess effect of CPT on CD4 count. RESULTS: Data from 468 CPT-exposed and 768 CPT-unexposed women were analyzed. CPT was associated with protection against malaria versus IPTp (hazard ratio: 0.35, 95% Confidence Interval (CI): 0.20, 0.60). After adjustment for time period this effect was not statistically significant (adjusted hazard ratio: 0.66, 95% CI: 0.28, 1.52). Among women receiving and not receiving CPT, rates of low birth weight (7.1% versus 7.6%) and preterm birth (23.5% versus 23.6%) were similar. CPT was associated with lower CD4 counts 24 weeks postpartum in women receiving (-77.6 cells/ µ L, 95% CI: -125.2, -30.1) and not receiving antiretrovirals (-33.7 cells/ µ L, 95% CI: -58.6, -8.8). CONCLUSIONS: Compared to IPTp, CPT provided comparable protection against malaria in HIV-infected pregnant women and against preterm birth or low birth weight. Possible implications of CPT-associated lower CD4 postpartum warrant further examination.

Lessons learned from a rural, community-based cervical cancer screen-and-treat pilot study in Malawi.

Objectives: Invasive cervical cancer (ICC) is the leading cause of cancer-related death among women in Malawi. Barriers to screening for ICC in Malawi, such as long distances to health facilities and lack of public education about ICC, have hindered participation of women in ICC prevention programs. Given the burden of disease and barriers to screening, we implemented a community-based ICC screen-and-treat pilot study and present its successes and challenges. Study design: This study was a screen-and-treat pilot study using Visual Inspection with Acetic acid (VIA) for screening and same-day thermal ablation for treatment of pre-cancerous lesions. The pilot was implemented in four rural community settings in Lilongwe District, Malawi. Methods: With consultation from local leaders, as well as the UNC Project-Malawi Community Department and the Community Advisory Board, a team of researchers designed a rural, community-based ICC screen-and-treat pilot study. Over a 5-week period, we travelled to four rural communities to provide information about and screening for ICC and HIV through our study. The four selected rural locations were about an hour drive from Lilongwe City, Malawi. Detailed field notes were taken by study staff and then later analyzed and categorized as either strengths or challenges. Results: Successes included support from local leaders, high uptake of screening (408 women underwent VIA, representing 88% of eligible women), positive experiences during screening, and good communication between study staff and participants. This communication enabled us to quickly address misperceptions about the study intent and procedures and to better understand some of the barriers to care. Challenges included insufficient medication for diagnosed sexually transmitted infections, finding ways to engage interested women who were ineligible due to young age, and not screening interested women because they needed male partner approval. Conclusion: Community-based screen-and-treat programs with thermal ablation for ICC can be an effective way to engage hard-to-reach women in ICC preventive care. Our findings support existing literature which suggests that involvement of local leadership, women from the community, and their male partners, as well as ongoing peer education, may facilitate greater participation in ICC screening and treatment. In addition, we found ongoing communication between study staff and participants to be mutually beneficial. Finally, we suggest that future interventions consider bundling sexually transmitted infection treatment into ICC preventive care when engaging hard-to-reach populations.

Prospective Newborn Screening for Sickle Cell Disease and Other Inherited Blood Disorders in Central Malawi.

Objectives: Newborn screening in the United States and Europe allows early identification of congenital disorders but does not yet exist in most low-resource settings, especially in sub-Saharan Africa. Newborn screening can identify multiple inherited hematological disorders, but feasibility and effectiveness for Africa are not fully determined. Methods: Surplus dried blood spot collected in Central Malawi through the HIV Early Infant Diagnosis surveillance program were repurposed and tested by isoelectric focusing for sickle cell disease and trait. Additional genetic testing identified G6PD deficiency and alpha thalassemia. Results: Testing of 10,529 cards revealed an overall sickle cell trait prevalence of 7.0% (range 3.9-9.7% by district); 10 of 14 infants identified with sickle cell disease (prevalence 0.1%) were located and received care at a specialized clinic. Subsequent testing of 1,329 randomly selected cards identified alpha thalassemia trait in 45.7% of samples, and G6PD deficiency in 20.4% of males and 3.4% of females, with 29.0% of females as heterozygous carriers. Conclusion: Inherited hematological disorders are common in Central Malawi; early identification through newborn screening can improve clinical outcomes and should be supported throughout Africa.

Experiences and beliefs of Malawian women who have delivered with a traditional birth attendant.

OBJECTIVE: To explore the beliefs and experiences of Malawian women who have delivered with a traditional birth attendant (TBA). METHODS: In a qualitative study, 20 face-to-face in-depth interviews and three focus group discussions were conducted between February and May 2013. Women aged 18 years or older and who had a history of delivery with a TBA were recruited from three health centers in Lilongwe District. Their responses were independently coded, and content analysis was used to develop themes and subthemes. RESULTS: A total of 46 women participated. Most participants cited difficulties relating to transport and/or unsupportive or unavailable husbands as factors that prohibited their delivery at a health facility. Most had not had a specific delivery plan. The participant responses indicated a discordance between knowledge and practices for safe delivery. CONCLUSION: Strategies to decrease deliveries with TBAs should focus on helping women to develop delivery plans to cope with the potential social or situational obstacles of getting to a facility. Women desire health facilities that provide quality care, emotional support, and personalized care during labor and delivery.
