RESUMEN

Insufficient progress has been made to reduce morbidity and mortality for women, children and adolescents particularly in Humanitarian and Fragile settings (HFS). Midwives play a critical and unique role in ensuring communities receive quality and safe essential sexual, reproductive, maternal, newborn, child, and adolescent health services. A lack of knowledge exists on the availability and experiences of midwifery services in HFS. This manuscript provides an overview of the midwifery density in HFS and a synthesis of the experiences of women receiving midwifery care, and barriers and facilitators for midwives providing essential SRMNCAH services in HFS. Guided by an expert committee, a concurrent mixed methods approach was applied, using secondary analysis of primary quantitative and qualitative data sources. Quantitative analysis of the global distribution of midwives compared to fragility was undertaken. Qualitative analysis of experiences of receipt and provision of midwifery care was undertaken across four settings providing humanitarian care. There is a critically low density of midwives in humanitarian and fragile settings. Sub-Saharan Africa accounts for the highest levels of fragility yet lowest density of midwives able to provide SRMNCAH services. Lack of finances both constrains midwives from effectively providing services and prevent communities from utilising services. Sub-optimal working conditions through rising workloads, insufficient and/or inconsistent resources were frequently reported to impede midwives from providing care in HFS. Uniquely for HFS, threats to the safety and security of midwives to conduct their work was widely reported. Key facilitators identified included, complex adaptive health system designs to respond effectively to the rapidly changing HFS environment, realisation of supporting "power, agency and status" as instrumental for midwives to provide quality care and promotion of community-centric approaches may enable continuity of care and uptake of essential SRMNCAH services. Midwives are critical to protect the health and well-being of communities. They require urgent protection and prioritisation in HFS areas where the need is greatest.

RESUMEN

BACKGROUND: Pre-labour rupture of membranes (PROM) at term is a common event whose management varies from centre to centre. The practice at the Kenyatta National Hospital (KNH) for patients with PROM at term is to initiate delivery of the patient soon on admission with intravenous oxytocin, if there are no contraindications to vaginal delivery. However, in PROM at term, if the cervix is not ripe, vaginal administration of prostaglandin pessaries for cervical ripening is not possible when there is active draining of liquor, thus use of intravenous oxytocin may take a very long time or fail all together. Oral misoprostol at low doses has been found to be a safe and effective agent for labour induction in numerous studies carried out in the developed world, where there are better resources for monitoring of labour. None of the studies has been carried out in Kenya, a limited resource country. Therefore, there is a need to determine the effectiveness and safety of oral misoprostol solution at the KNH, a limited resource set up. OBJECTIVE: To determine the effectiveness and safety of 2-hourly 20 mcg oral misoprostol solution compared to the standard intravenous oxytocin in labour induction in mothers with pre-labour rupture of membranes at term at the Kenyatta National Hospital. DESIGN: An unblinded randomised clinical trial. SETTING: Kenyatta National Hospital Labour Ward Unit. PARTICIPANTS: Eighty three pregnant women with pre-labour rupture of membranes at term without an indication for Caeserian section were consented and randomised for labour induction with either oral misoprostol at a dose of 20mcg 2-hourly up to a maximum of 4-doses, or with intravenous oxytocin according to the WHO protocol. MAIN OUTCOME MEASURES: Induction to delivery interval; maternal complications and early neonatal outcomes. RESULTS: The overall induction success rates in the misoprostol arm was 81% versus 83% in the oxytocin arm (P = 0.447). The mean induction to vaginal delivery interval in the misoprostol arm was 8.4 hours as compared to 9.45 hours in the oxytocin arm (P = 0.116). The induction to active labour interval was similar in the two study arms. The mean induction to active labour in the misoprostol arm was 4.02 hours as versus 4.51 hours in the oxytocin arm (P = 0.223 ). Two women who had failed induction with misoprostol were augmented with oxytocin and delivered vaginally. The Caesarean section rates were 19% in the misoprostol arm and 17% in the oxytocin arm (P = 0.447), which was not statistically significant. The maternal outcomes were similar in the two study arms. Four women had tachysystole in the misoprostol arm, compared to three in the oxytocin arm (P = 0.253). In the misoprostol arm two women had hypertonus compared to three in the oxytocin arm (P = 0.322).There was one case of hyperstimulation in the misoprostol arm and two in in the oxytocin arm. There were no differences in the foetal/neonatal outcomes. No baby had an Apgar score of less than seven at one or five minutes. No baby was admitted to the New Born Unit in either of the two arms. There was no case of a still birth in either of the study arms. There was no significant difference in the passage of meconium between the two arms, 39% in the misoprostol arm and 35.7% in the oxytocin arm (P = 0.755). The passage of meconium did not impact on the neonatal outcomes. CONCLUSION: Oral misoprostol solution 20mcg 2-hourly is as safe and effective as the standard intravenous oxytocin for labour induction in women presenting with prelabour rupture of membranes at term at the Kenyatta National Hospital.

RESUMEN

We estimated type-specific prevalence of human papillomavirus (HPV) and examined risk factors for abnormal cervical cytology among 296 female sex workers from Nairobi, Kenya. Over half (54%) were infected with a high-risk (HR) HPV type, of which HPV16 and 52 were the most common types. HIV-1 prevalence was 23% and HIV-1 sero-positivity was associated with high-grade cervical lesions, particularly among women with CD4 count less than 500 cells/mm(3) (odds ratio [OR] = 6.9; 95% confidence interval [CI]: 1.7-24.9). Among women who had normal cytology at the time of entry into the study, the risk of having an abnormal Pap smear within one year was significantly elevated for women with multiple HPV types at study entry (adjusted odds ratio [aOR] = 6.0; 95% CI: 2.3-15.7) and with a subset of HR HPV types (aOR = 4.2; 95% CI: 1.6-11.2). Detection of multiple concurrent HPV infections may be a useful marker to identify women at risk of developing precancerous lesions in populations of high HPV prevalence.

RESUMEN

SETTING: Sex Workers Outreach Programme Clinic, Korogocho, Nairobi, Kenya. OBJECTIVE: In a cohort of sex workers, to determine 1) the prevalence of cervical intra-epithelial neoplasia (CIN) and its association with human immunodeficiency virus-1 (HIV-1) infection, and 2) the incidence rate of CIN during the 3-year follow-up from December 2009 to December 2012. DESIGN: Prospective nested cohort study. RESULTS: Of the 350 women enrolled, the median age was 29 years (range 18-49); 84 (24%) were HIV-1-infected. At enrollment, 54 (15%) had an abnormal cytology, 39 (11%) had low-grade intra-epithelial lesions (LSIL) and 15 (4%) high-grade intraepithelial lesions (HSIL). HIV-1-infected women were 2.7 times (95%CI 1.7-4.4) more likely to have CIN than non-HIV-1-infected women. Among HIV-1-infected women, the prevalence of LSIL and HSIL was 2.5 times (95%CI 1.2-5.1) and seven times (95%CI 2.3-23.3) greater than among non-HIV-infected women. During the follow-up period, 39 (11%) women had incident CIN (6.6/100 person years [py]), with no difference by HIV status, i.e., respectively 7.9/100 py and 6.3/100 py in HIV-1-infected and non-HIV-1-infected women. CONCLUSION: The prevalence and incidence of CIN among HIV-1-infected sex workers was high; early, regular screening and follow-up of this life-threatening condition is therefore recommended.

RESUMEN

BACKGROUND: We assessed the association of human papillomavirus (HPV) infection and cervical intraepithelial neoplasia (CIN) with various characteristics, CD4 count and use of combination antiretroviral therapy (cART) among HIV-positive women. METHODS: Cross-sectional study of 498 HIV-positive women who underwent HPV PCR-based testing, cytology, and systematic cervical biopsy. RESULTS: In all, 68.7% of women were HPV-positive, 52.6% had high-risk (hr) HPV, and 40.2% multiple type infections. High-risk human papillomavirus-positivity did not vary significantly by age but it was negatively associated with education level. The most frequent types in 113 CIN2/3 were HPV16 (26.5%), HPV35 (19.5%), and HPV58 (12.4%). CD4 count was negatively associated with prevalence of hrHPV (P<0.001) and CIN2/3 among non-users of cART (P=0.013). Combination antiretroviral therapies users (≥2 year) had lower hrHPV prevalence (prevalence ratio (PR) vs non-users=0.77, 95% confidence interval (CI): 0.61-0.96) and multiple infections (PR=0.68, 95% CI: 0.53-0.88), but not fewer CIN2/3. The positive predictive value of hrHPV-positivity for CIN2/3 increased from 28.9% at age <35 years to 53.3% in ≥45 years. CONCLUSION: The burden of hrHPV and CIN2/3 was high and it was related to immunosuppression level. Combination antiretroviral therapies ( ≥2 year) use had a favourable effect on hrHPV prevalence but cART in our population may have been started too late to prevent CIN2/3.

RESUMEN

BACKGROUND AND OBJECTIVES: Blood safety and sufficiency are major challenges in Kenya and other sub-Saharan African countries forcing many countries to rely on family replacement donors (FRD). We analysed data from a national AIDS indicator survey to describe blood donors in Kenya and potential risks of transfusion transmissible infections (TTI) comparing voluntary donors and FRD. MATERIALS AND METHODS: A population-based, cross-sectional survey was conducted in 2007 among 15- to 64-year-olds. Consenting participants were interviewed about blood donation history and were tested for HIV, HSV-2 and syphilis. RESULTS: Of the 17,940 people surveyed, 445 (2·3%) reported donating blood in the prior 12 months. Sixty-four per cent were voluntary donors, and the rest were FRD. Compared to FRD, the majority of voluntary donors were <25 years old (59% versus 18%), from the highest wealth quintile (57% versus 42%) and single (64% versus 23%). In addition, voluntary donors were less likely to have been sexually active than replacement donors (43% versus 13%). HIV prevalence was lower among voluntary donors than among FRD (2·6% versus 7·4%, P-value=0·07). CONCLUSIONS: The majority of blood donors in Kenya are voluntary with lower potential risk of TTI.

RESUMEN

BACKGROUND: Most persons who are infected with human immunodeficiency virus type 1 (HIV-1) are also infected with herpes simplex virus type 2 (HSV-2), which is frequently reactivated and is associated with increased plasma and genital levels of HIV-1. Therapy to suppress HSV-2 reduces the frequency of reactivation of HSV-2 as well as HIV-1 levels, suggesting that suppression of HSV-2 may reduce the risk of transmission of HIV-1. METHODS: We conducted a randomized, placebo-controlled trial of suppressive therapy for HSV-2 (acyclovir at a dose of 400 mg orally twice daily) in couples in which only one of the partners was seropositive for HIV-1 (CD4 count, > or = 250 cells per cubic millimeter) and that partner was also infected with HSV-2 and was not taking antiretroviral therapy at the time of enrollment. The primary end point was transmission of HIV-1 to the partner who was not initially infected with HIV-1; linkage of transmissions was assessed by means of genetic sequencing of viruses. RESULTS: A total of 3408 couples were enrolled at 14 sites in Africa. Of the partners who were infected with HIV-1, 68% were women, and the baseline median CD4 count was 462 cells per cubic millimeter. Of 132 HIV-1 seroconversions that occurred after randomization (an incidence of 2.7 per 100 person-years), 84 were linked within couples by viral sequencing: 41 in the acyclovir group and 43 in the placebo group (hazard ratio with acyclovir, 0.92, 95% confidence interval [CI], 0.60 to 1.41; P=0.69). Suppression with acyclovir reduced the mean plasma concentration of HIV-1 by 0.25 log(10) copies per milliliter (95% CI, 0.22 to 0.29; P<0.001) and the occurrence of HSV-2-positive genital ulcers by 73% (risk ratio, 0.27; 95% CI, 0.20 to 0.36; P<0.001). A total of 92% of the partners infected with HIV-1 and 84% of the partners not infected with HIV-1 remained in the study for 24 months. The level of adherence to the dispensed study drug was 96%. No serious adverse events related to acyclovir were observed. CONCLUSIONS: Daily acyclovir therapy did not reduce the risk of transmission of HIV-1, despite a reduction in plasma HIV-1 RNA of 0.25 log(10) copies per milliliter and a 73% reduction in the occurrence of genital ulcers due to HSV-2.

RESUMEN

OBJECTIVES: Mycoplasma genitalium has been associated with cervicitis, endometritis, and tubal factor infertility. Because the ability of this bacterium to ascend and infect the fallopian tube remains undefined, we performed an investigation to determine the prevalence of M genitalium in fallopian tube, endometrial, and cervical specimens from women laparoscopically diagnosed with acute salpingitis in Nairobi, Kenya. METHODS: Women presenting with pelvic inflammatory disease were laparoscopically diagnosed with salpingitis. Infection with M genitalium in genital specimens was determined by polymerase chain reaction (PCR). RESULTS: Of 123 subjects with acute salpingitis, M genitalium was detected by PCR in the cervix and/or endometrium in nine (7%) participants, and in a single fallopian tube specimen. In addition, those infected with M genitalium were more often HIV infected than women not infected by M genitalium (seven of nine (78%) v 42 of 114 (37%), p<0.03). CONCLUSIONS: M genitalium is able to ascend into the fallopian tube, but its association with tubal pathology requires further investigation.

RESUMEN

OBJECTIVE: Although non-ulcerative sexually transmitted diseases (STD) and bacterial vaginosis are implicated as cofactors in heterosexual HIV-1 transmission, the mechanisms have not been defined. Recent in vitro data suggest that interleukin (IL)-10 may increase susceptibility of macrophages to HIV-1 infection. Therefore, we performed this study to assess whether non-ulcerative STD are associated with detection of IL-10 in the female genital tract. METHODS: Women with clinical pelvic inflammatory disease with or without cervicovaginal discharge were recruited from an STD clinic in Nairobi, Kenya. Endocervical and endometrial specimens were obtained for Neisseria gonorrhoeae and Chlamydia trachomatis DNA detection, Trichonomas vaginalis culture, and CD4 and CD8 T-cell enumeration. Bacterial vaginosis was diagnosed by Gram stain. IL-10 was detected in endocervical specimens using enzyme-linked immunosorbent assay. Blood was obtained for HIV-1 serology. RESULTS: One hundred and seventy-two women were studied. N. gonorrhoeae, C. trachomatis, bacterial vaginosis, and T. vaginalis were detected in 38 (21%), 17 (9%), 71 (43%), and 22 (12%) women, respectively. Cervical IL-10 was detected more often in women with N. gonorrhoeae [adjusted odds ratio (AOR), 3.4; 95% confidence interval (CI), 1.4-8.4], C. trachomatis (AOR, 4.4; 95% CI, 1.2-15.6), and bacterial vaginosis (AOR, 3.1; 95% CI, 1.4-6.9) than in women without these infections. CONCLUSIONS: The association of non-ulcerative STD and bacterial vaginosis with increased frequency of IL-10 detection in endocervical secretions suggests a potential mechanism through which these infections may alter susceptibility to HIV-1 infection in women.
