Association between HSV-2 and HIV serostatus in pregnant women of known HIV serostatus attending Mulago Hospital antenatal clinic, Kampala, Uganda
(The Journal of Infection in Developing Countries, 2009) Nakubulwa, Sarah; Mirembe, Florence M.; Kaye, Dan K.; Kaddu-Mulindwa, Deogratias
Background: Studies show that STIs such as HSV-2 increase the probability of HIV-1 acquisition and enhance transmission by increasing susceptibility and infectiousness respectively. The objective of this study was to compare the proportion of HSV-2 in HIV-positive and HIV-negative pregnant mothers attending the antenatal clinic in Mulago Teaching Hospital in Kampala, Uganda. Methods: This case control study included 50 pregnant women who were HIV positive and 200 controls of pregnant women who were HIV negative and were aware of their serostatus. Data was collected in two parts: the first part involved a pretested interviewer-administered semi-structured questionnaire for socio-demographic characteristics, sexual and behavioral history. The second part consisted of a serological test using an ELISA assay specific for IgG against viral glycoprotein G, specific to HSV-2. Results: The proportion of HSV-2 was 86% (43/50) among the HIV-positive cases and 62% (125/200) among the HIV-negative controls. The odds of being HSV-2 seropositive was 3.7 times higher (95% CI was 1.58 – 8.61) in HIV-positive cases than in the HIV negative controls. The odds of HSV-2 was significantly increased to 5.32 (95 CI was 1.92 – 14.73) among cases when adjustment was done for age, education, marital status, religion, age at first sexual experience, lifetime partners, type of earning, and whether the mother involved the partner in seeking treatment for sexually transmitted diseases. Conclusion: The proportion of HSV-2 was higher in HIV-positive cases than in the HIV negative controls.

(BMC pregnancy and childbirth, 2016) Nakimuli, Annettee; Nakubulwa, Sarah; Kakaire, Othman; Osinde, Michael O.; Mbalinda, Scovia N.; Kakande, Nelson; Nabirye, Rose C.; Kaye, Dan K.
Hypertensive disorders of pregnancy are a major cause of morbidity and mortality. The objective was to estimate the disease burden attributable to hypertensive disorders of pregnancy in two referral hospitals in Uganda. Methods: Through a prospective cohort study conducted in Jinja and Mulago hospitals in Uganda from March 1, 2013 and February 28, 2014, hypertension-related cases were analyzed. Maternal near miss cases were defined according to the WHO criteria. Maternal deaths were also analyzed. The maternal near miss incidence ratio, the case-specific severe maternal outcome ratio, the case-specific maternal mortality ratio and the case-fatality ratio were computed. Results: Of 403 women with hypertensive disorders of pregnancy, 218 (54.1 %) had severe preeclampsia, 172 (42.7 %) had eclampsia, and 13 had chronic hypertension or Hemolysis, elevated liver enzymes or low platelets (HELLP) syndrome. The case-specific maternal near miss incidence ratios was 8.60 per 1,000 live births for all hypertensive disorders, 3.06 per 1,000 live births for severe preeclampsia and 5.11 per 1,000 live births for eclampsia. The casespecific severe maternal outcome ratio was 9.37 per 1,000 live births for all hypertensive disorders, and was 3.25 per 1,000 live births for severe preeclampsia and 5.61 per 1,000 live births for eclampsia. The case-specific maternal mortality ratio was 780 per 100,000 live births for all hypertensive disorders, and was 1940 per 100,000 live births for severe preeclampsia and 501 per 100,000 live births for eclampsia. The case-fatality ratio was 5.1 % overall (for all hypertensive disorders), but was 8 times higher for eclampsia compared to severe preeclampsia. Cyanosis, abnormal respiration, oliguria, circulatory collapse, coagulopathy, thrombocytopenia, and elevated serum lactate were significantly associated with severe maternal outcomes. Conclusion: There is high morbidity attributable to hypertensive disorders in pregnancy. Since some of the complications associated with morbidity can be recognized early, it is possible to prevent severe morbidity through early intervention with delivery, antihypertensive therapy and prophylactic magnesium sulphate treatment. The findings highlight the feasibility of implementing a facility-based surveillance system for severe maternal morbidity due to hypertensive disorders.
Doctoral training in Uganda: evaluation of mentoring best practices at Makerere university college of health sciences
(BMC Medical Education, 2014) Nakanjako, Damalie; Katamba, Achilles; Kaye, Dan K.; Okello, Elialilia; Kamya, Moses R.; Sewankambo, Nelson; Mayanja-Kizza, Harriet
Good mentoring is a key variable for determining success in completing a doctoral program. We identified prevailing mentoring practices among doctoral students and their mentors, identified common challenges facing doctoral training, and proposed some solutions to enhance the quality of the doctoral training experience for both candidates and mentors at Makerere University College of Health Sciences (MakCHS). Methods: This cross-sectional qualitative evaluation was part of the monitoring and evaluation program for doctoral training. All doctoral students and their mentors were invited for a half-day workshop through the MakCHS mailing list. Prevailing doctoral supervision and mentoring guidelines were summarised in a one-hour presentation. Participants were split into two homogenous students’ (mentees’) and mentors’ groups to discuss specific issues using a focus group discussion (FGD) guide, that highlighted four main themes in regard to the doctoral training experience; what was going well, what was not going well, proposed solutions to current challenges and perceived high priority areas for improvement. The two groups came together again and the note-takers from each group presented their data and discussions were recorded by a note-taker. Results: Twelve out of 36 invited mentors (33%) and 22 out of 40 invited mentees (55%) attended the workshop. Mentors and mentees noted increasing numbers of doctoral students and mentors, which provided opportunities for peer mentorship. Delays in procurement and research regulatory processes subsequently delayed students’ projects. Similarly, mentees mentioned challenges of limited; 1) infrastructure and mentors to support basic science research projects, 2) physical office space for doctoral students and their mentors, 3) skills in budgeting and finance management and 4) communication skills including conflict resolution. As solutions, the team proposed skills’ training, induction courses for doctoral students-mentor teams, and a Frequently Asked Questions’ document, to better inform mentors’, mentees’ expectations and experiences. Conclusion: Systemic and infrastructural limitations affect the quality of the doctoral training experience at MaKCHS. Clinical and biomedical research infrastructure, in addition to training in research regulatory processes, procurement and finance management, communication skills and information technology, were highlighted as high priority areas for strategic interventions to improve mentoring within doctoral training of clinician scientists.
Domestic violence as risk factor for unwanted pregnancy and induced abortion in Mulago Hospital, Kampala, Uganda
(Tropical Medicine & International Health, 2006) Kaye, Dan K.; Mirembe, Florence M.; Bantebya, Grace; Johansson, Annika; Ekstrom, Anna Mia
To compare pregnancy intention and domestic violence among women with induced and spontaneous abortion. Case-control study in Mulago Hospital, Uganda, from September 2003 to June 2004 of 942 women seeking post-abortion care. Direct inquiry, records review and clinical examination identified 333 with induced abortion (cases) and 609 with spontaneous abortion (controls), who were compared regarding socio-demographic characteristics, contraceptive use, domicile (rural or urban, nuclear or extended families), pregnancy intention, household decision-making and domestic violence. Data was analysed with EPI-INFO and STATA, using Student t-test and analysis of variance for continuous and chi-square for categorical variables. Stratified and multivariate logistic regression analyses were used to adjust for confounding and interaction at the 95% confidence level. Cases significantly differed from controls as they were younger or more often single; had lower parity and education, less household decision-making and fewer living children. They were similar to controls (P > 0.05) regarding employment, spouse’s age, years spent in marital relationship and domicile. Cases more frequently (P < 0.001) had mistimed, unplanned or unwanted pregnancy at conception and presentation. Cases were more likely to have a recent history of domestic violence (physical, sexual or psychological) [OR: 18.7 (95%CI: 11.2–31.0)] after adjusting for age, pregnancy intention and marital status. Domestic violence is a risk factor for unwanted pregnancy and induced abortion among women seeking post-abortion care.
Domestic violence during pregnancy and risk of low birthweight and maternal complications: a prospective cohort study at Mulago Hospital, Uganda
(Tropical Medicine & International Health, 2006) Kaye, Dan K.; Mirembe, Florence M.; Bantebya, Grace; Johansson, Annika; Ekstrom, Anna Mia
To investigate whether domestic violence during pregnancy is a risk factor for antepartum hospitalization or low birthweight (LBW) delivery. A prospective cohort study was conducted in Mulago hospital, Kampala, Uganda, among 612 women recruited in the second pregnancy trimester and followed up to delivery, from May 2004 through July 2005. The exposure (physical, sexual or psychological violence during pregnancy) was assessed using the Abuse Assessment Screen. The relative and attributable risks of LBW and antepartum hospitalization were estimated using multivariate logistic regression analysis. The 169 women [27.7% 95% CI (24.3–31.5%)] who reported domestic violence during pregnancy did not differ significantly from the unexposed regarding sociodemographic characteristics, but differed significantly (P < 0.05) regarding domicile variables (had less household decision-making power, more resided in extended families and more had unplanned pregnancy). They delivered babies with a mean birthweight 2647.5 ± 604 g, on average 186 g [(95% CI 76–296); P ¼ 0.001] lower than those unexposed. After adjusting for age, parity, number of living children, pregnancy planning, domicile and number of years in marriage, the relative risk (RR) of LBW delivery among women exposed to domestic violence was 3.78 (95% CI 2.86–5.00). Such women had a 37% higher risk of obstetric complications (such as hypertension, premature rupture of membranes and anaemia) that necessitated antepartum hospitalization [RR 1.37 (95% CI 1.01–1.84)]. In this pregnancy cohort, domestic violence during pregnancy was a risk factor for LBW delivery and antepartum hospitalization.
Effect of suppressive acyclovir administered to HSV-2 positive mothers from week 28 to 36 weeks of pregnancy on adverse obstetric outcomes: a double-blind randomized placebo-controlled trial
(Reproductive health, 2017) Nakubulwa, Sarah; Kaye, Dan K.; Bwanga, Freddie; Mbona Tumwesigye, Nazarius; Nakku-Joloba, Edith; Mirembe, Florence
Acyclovir (ACV) given to HSV-2 positive women after 36 weeks reduces adverse outcomes but its benefit at lower gestation was undocumented. We determined the effect of oral acyclovir administered from 28 to 36 weeks on premature rupture of membranes (PROM) primarily and preterm delivery risk. This was a randomized, double-blind placebo-controlled trial among 200 HSV-2 positive pregnant women at 28 weeks of gestation at Mulago Hospital, Uganda. Participants were assigned randomly (1:1) to take either acyclovir 400 mg orally twice daily (intervention) or placebo (control) from 28 to 36 weeks. Both arms received acyclovir after 36 weeks until delivery. Development of Pre-PROM by 36 weeks and preterm delivery were outcomes. One hundred women were randomized to acyclovir and 100 to placebo arms between January 2014 and February 2015. There was tendency towards reduction of incidence of PROM at 36 weeks but this was not statistically significant (4.0% versus 10.0%; RR 0.35; 95% 0.11–1.10) in the acyclovir and placebo arms respectively. However, there was a significant reduction in the incidence of preterm delivery (11.1% versus 23.5%; RR 0.41; 95% 0.20–0.85) in the acyclovir and placebo arms respectively. Oral acyclovir given to HSV-2 positive pregnant women from 28 to 36 weeks reduced incidence of preterm delivery but did not significantly reduce incidence of pre-PROM.
Escaping the triple trap: Coping strategies of pregnant adolescent survivors of domestic violence in Mulago hospital, Uganda
(Scandinavian journal of public health, 2007) Kaye, Dan K.; Mia Ekstrom, Anna; Johansson, Annika; Bantebya, Grace; Mirembe, Florence M.
Why domestic violence survivors develop adverse outcomes following domestic violence during pregnancy is unclear, but may depend on how survivors cope with the stress of violence. The objective was to describe strategies pregnant adolescents employ in coping with domestic violence. Methods: This was a qualitative study involving 16 in-depth interviews with adolescent domestic violence survivors who attended the antenatal clinic in Mulago hospital, Kampala, Uganda, from January to May 2004. Theoretical sampling, necessitated by the emergent theory from sequential data collection and analysis, further provided diversity of experiences from adolescents of different ages, parity, pregnancy duration, and socioeconomic status until saturation was reached. Data were analyzed using grounded theory. Findings: Survivors described varied experiences of physical, sexual, and psychological violence. Coping strategies employed were analyzed as: Minimizing damage – decreasing impact and severity of violence, withdrawal – physical or social withdrawal, seeking help and retaliation (fighting back). Coping strategies were influenced by adolescence and pregnancy, and are explained in relation to theories of coping with stress. Conclusions: Coping strategies adopted by pregnant adolescent survivors range from problem focused approaches to emotion-focused approaches. Coping strategies are influenced markedly by adolescence and pregnancy.
Genital infections and risk of premature rupture of membranes in Mulago Hospital, Uganda: a case control study
(BMC research notes, 2015) Nakubulwa, Sarah; Kaye, Dan K.; Bwanga, Freddie; Mbona Tumwesigye, Nazarius; Mirembe, Florence M.
Inflammatory mediators that weaken and cause membrane rupture are released during the course of genital infections among pregnant women. We set out to determine the association of common genital infections (Trichomonas vaginalis, syphilis, Neisseria gonorrhea, Chlamydia trachomatis, Group B Streptococcus, Bacterial vaginosis, Herpes Simplex Virus Type 2 and candidiasis) and premature rupture of membranes in Mulago hospital, Uganda. Methods: We conducted an unmatched case–control study among women who were in the third trimester of pregnancy at New Mulago hospital, Uganda. The cases had PROM and the controls had intact membranes during latent phase of labour in the labour ward. We used interviewer-administered questionnaires to collect data on sociodemographic characteristics, obstetric and medical history. Laboratory tests were conducted to identify T. vaginalis, syphilis, N. gonorrhea, C. trachomatis, Group B Streptococcus, Bacterial vaginosis, Herpes Simplex Virus Type 2 (HSV-2) and candidiasis. Logistic regression models were used to estimate the odds ratios (OR) and 95 % CI of the association between genital infections and PROM.
Incidence and risk factors for herpes simplex virus type 2 seroconversion among pregnant women in Uganda: A prospective study
(The Journal of Infection in Developing Countries, 2016) Nakubulwa, Sarah; Kaye, Dan K.; Bwanga, Freddie; Mbona Tumwesigye, Nazarius; Nakku-Joloba, Edith; Mirembe, Florence M.
Herpes simplex virus type 2 (HSV-2) acquired during pregnancy is associated with adverse outcomes such as perinatal HSV-2 transmission. HSV-2 seroconversion occurs within four weeks of HSV-2 acquisition. There was neither documented incidence nor risk factors for HSV-2 seroconversion during pregnancy in Uganda. The objective of this study was to determine the incidence and risk factors for HSV-2 seroconversion among pregnant women in Mulago Hospital, Uganda. Methodology: A prospective study of 200 consenting HSV-2-negative women between 26 and 28 weeks of gestation was done between November 2013 and October 2014. HSV-2 serostatus was determined using HerpeSelect HSV-2 enzyme-linked immunosorbent assay (ELISA). Interviewer-administered questionnaires were used to collect socio-demographic characteristics and sexual history. Human immunodeficiency virus (HIV) serostatus was obtained from antenatal records. A total of 191 women completed follow-up and repeat HSV-2 serology by 38 weeks. Negative binomial regression analysis was used to estimate risk ratios for risk factors for HSV-2 seroconversion. Results: Of 191 women, 15 (7.9%) seroconverted during pregnancy. Having multiple sexual partners, being in polygamous unions, and having HIV-positive serostatus were found to be risk factors for HSV-2 seroconversion. Conclusions: The incidence of HSV-2 seroconversion during pregnancy in Uganda was high. Multiple sexual partners, polygamy, and HIV-positive serostatus were risk factors for HSV-2 seroconversion during pregnancy. Strengthening health education on the avoidance of multiple sexual partners during pregnancy is paramount in prevention of HSV-2 seroconversion.
Maternal near misses from two referral hospitals in Uganda: a prospective cohort study on incidence, determinants and prognostic factors
(BMC pregnancy and childbirth, 2016) Nakimuli, Annettee; Nakubulwa, Sarah; Kakaire, Othman; Osinde, Michael O.; Mbalinda, Scovia N.; Nabirye, Rose C.; Kakande, Nelson; Kaye, Dan K.
Background: Maternal near misses occur more often than maternal deaths and could enable more comprehensive analysis of risk factors, short-term outcomes and prognostic factors of complications during pregnancy and childbirth. The study determined the incidence, determinants and prognostic factors of severe maternal outcomes (near miss or maternal death) in two referral hospitals in Uganda. Methods: A prospective cohort study was conducted between March 1, 2013 and February 28, 2014, where cases of severe pregnancy and childbirth complications were included. The clinical conditions included abortion-related complications, obstetric haemorrhage, hypertensive disorders, obstructed labour, infection and pregnancy-specific complications such as febrile illness, anemia and premature rupture of membranes. Near miss cases were defined according to the WHO criteria. Multivariate logistic regression analysis was conducted to identify prognostic factors for severe maternal outcomes. Results: Of 3100 women with severe obstetric complications, 130 (4.2 %) were maternal deaths and 695 (22.7 %) were near miss cases. Severe pre-eclampsia was the commonest morbidity (incidence ratio (IR) 7.0 %, case-fatality rate (CFR) 2.3 %), followed by postpartum haemorrhage (IR 6.7 %, CFR 7.2 %). Uterine rupture (IR 5.5 %) caused the highest CFR (17.9 %), followed by eclampsia (IR 0.4 %, CFR 17.8 %). The three groups (maternal deaths, near misses and non-life-threatening obstetric complications) differed significantly regarding gravidity and education level. The commonest diagnostic criteria for maternal near miss were admission to the high dependency unit (HDU) or to the intensive care unit (ICU). Thrombocytopenia, circulatory collapse, referral to a more specialized unit, intubation unrelated to anaesthesia, and cardiopulmonary resuscitation were predictive of maternal death (p < 0.05). Gravidity (ARR 1.4, 95 % C1 1.0–1.2); elevated serum lactate levels (ARR 4.5, 95 % CI 2.3–8.7); intubation for conditions unrelated to general anaesthesia (ARR 2.6 (95 % CI 1.2–5.7), cardiovascular collapse (ARR 4.9, 95 % CI 2.5–9.5); transfusion of 4 or more units of blood (ARR 1.9, 95 % CI 1.1–3.1); being an emergency referral (ARR 2.6, 95 % CI 1.2–5.6); and need for cardiopulmonary resuscitation (ARR 6.1, 95 % CI 3.2–11.7), were prognostic factors. Conclusions: The analysis of near misses is a useful tool in the investigation of severe maternal morbidity. The prognostic factors for maternal death, if instituted, might save many women with obstetric complications
Perinatal care in Western Uganda: Prevalence and factors associated with appropriate care among women attending three district hospitals
(PloS one, 2022) Muwema, Mercy; Kaye, Dan K.; Edwards, Grace; Nalwadda, Gorrette; Nangendo, Joanita; Okiring, Jaffer; Mwanja, Wilson; Ekong, Elizabeth N.; Kalyango, Joan N.; Nankabirwa, Joaniter I.
Perinatal mortality remains high globally and remains an important indicator of the quality of a health care system. To reduce this mortality, it is important to provide the recommended care during the perinatal period. We assessed the prevalence and factors associated with appropriate perinatal care (antenatal, intrapartum, and postpartum) in Bunyoro region, Uganda. Results from this study provide valuable information on the perinatal care services and highlight areas of improvement for better perinatal outcomes. Methods A cross sectional survey was conducted among postpartum mothers attending care at three district hospitals in Bunyoro. Following consent, a questionnaire was administered to capture the participants’ demographics and data on care received was extracted from their antenatal, labour, delivery, and postpartum records using a pre-tested structured tool. The care received by women was assessed against the standard protocol established by World Health Organization (WHO). Poisson regression with robust standard errors was used to assess factors associated with appropriate postpartum care. Results A total of 872 mothers receiving care at the participating hospitals between March and June 2020 were enrolled in the study. The mean age of the mothers was 25 years (SD = 5.95). None of the mothers received appropriate antenatal or intrapartum care, and only 3.8% of the participants received appropriate postpartum care. Factors significantly associated with appropriate postpartum care included mothers being >35 years of age (adjusted prevalence ratio [aPR] = 11.9, 95% confidence interval [CI] 2.8–51.4) and parity, with low parity (2–3) and multiparous (>3) mothers less likely to receive appropriate care than prime gravidas (aPR = 0.3, 95% CI 0.1–0.9 and aPR = 0.3, 95% CI 0.1–0.8 respectively). Conclusions Antenatal, intrapartum, and postpartum care received by mothers in this region remains below the standard recommended by WHO, and innovative strategies across the continuum of perinatal care need to be devised to prevent mortality among the mothers. The quality of care also needs to be balanced for all mothers irrespective of the age and parity.
The Social Construction and Context of Domestic Violence in Wakiso District, Uganda
(An International Journal for Research, Intervention and Care, 2005) Kaye, Dan K.; Mirembe, Florence; Ekstrom, Anna Mia; Bantebya, Grace; Johansson, Annika
This study explored community perceptions of factors associated with domestic violence, with an emphasis on events occurring during pregnancy. Ten focus group discussions, 14 key-informant interviews and four case vignettes were conducted in Wakiso district, Uganda between August and December 2003. Data were analyzed using thematic content analysis. Perceived motives and meanings, triggering as well as associated factors, perceived coping mechanisms and community support available for reducing domestic violence, especially that occurring during pregnancy, were identified. Urban migration, changing cultural values and men’s unemployment shift the balance of power in gender relations. Resultant male uncertainty and gender antagonism is associated with domestic violence. Family institutions such as extended family structure, relatives and in-laws were perceived as offering little protection. Factors triggering violence included failed negotiation of sexual relations, disagreement concerning the division of labor within the household and misconceptions about the physical and physiological changes, both dietary and behavioral, which occur in pregnancy.
Still births, neonatal deaths and neonatal near miss cases attributable to severe obstetric complications: a prospective cohort study in two referral hospitals in Uganda
(BMC pediatrics, 2015) Nakimuli, Annettee; Mbalinda, Scovia N.; Nabirye, Rose C.; Kakaire, Othman; Nakubulwa, Sarah; Osinde, Michael O.; Kakande, Nelson; Kaye, Dan K.
Neonatal near miss cases occur more often than neonatal deaths and could enable a more comprehensive analysis of risk factors, short-term outcomes and prognostic factors in neonates born to mothers with severe obstetric complications. The objective was to assess the incidence, presentation and perinatal outcomes of severe obstetric morbidity in two referral hospitals in Central Uganda. Methods: A prospective cohort study was conducted between March 1, 2013 and February 28, 2014, in which all newborns from cases of severe pregnancy and childbirth complications were eligible for inclusion. The obstetric conditions included obstetric haemorrhage, hypertensive disorders, obstructed labour, chorioamnionitis and pregnancy-specific complications such as malaria, anemia and premature rupture of membranes. Still births, neonatal deaths and neonatal near miss cases (defined using criteria that employed clinical features, presence of organ-system dysfunction and management provided to the newborns were compiled). Stratified and multivariate logistic regression analysis was conducted to identify risk factors for perinatal death. Results: Of the 3100 mothers, 192 (6.2%) had abortion complications. Of the remainder, there were 2142 (73.1%) deliveries, from whom the fetal outcomes were 257 (12.0%) still births, 369 (17.2%) neonatal deaths, 786 (36.7%) neonatal near misses and 730 (34.1%) were newborns with no or minimal life threatening complications. Of the 235 babies admitted to the neonatal intensive care unit (NICU), the main reasons for admission were prematurity for 64 (26.8%), birth asphyxia for 59 (23.7%), and grunting respiration for 26 (11.1%). Of the 235 babies, 38 (16.2%) died in the neonatal period, and of these, 16 died in the first 24 hours after admission. Ruptured uterus caused the highest case-specific mortality of 76.8%, and led to 16.9% of all newborn deaths. Across the four groups, there were significant differences in mean birth weight, p = 0.003. Conclusions: Antepartum hemorrhage, ruptured uterus, severe preeclampsia, eclampsia, and the syndrome of Hemolysis, Elevated Liver Enzymes, Low Platelets (HELLP syndrome), led to statistically significant attributable risk of newborn deaths (still birth or neonatal deaths). Development of severe maternal outcomes, the mothers having been referred, and gravidity of 5 or more were significantly associated with newborn deaths.
