RESUMO

BACKGROUND: The perinatal mortality of 70 deaths per 1,000 total births in Uganda is unacceptably high. Perinatal death audits are important for improvement of perinatal care and reduction of perinatal morality. We integrated perinatal death audits in routine care, and describe its effect on perinatal mortality rate at Nsambya Hospital. METHODS: This was a retrospective descriptive study conducted from March - November 2008. An interdisciplinary hospital team conducted weekly perinatal death reviews. Each case was summarized and discussed, identifying gaps and cause of death. Local solutions were implemented according to the gaps identified from the audit process. RESULTS: Of the 350 perinatal deaths which occurred, 120 perinatal deaths were audited. 34.2% were macerated still births, 31.7% fresh still births and 34.2% early neonatal deaths. Avoidable factors included: poor neonatal resuscitation skills, incorrect use of the partographs and delay in performing caesarean sections. Activities implemented included: three skills sessions of neonatal resuscitation, introduction of Continuous positive airway pressure (CPAP) for babies with respiratory distress, updates on use of partographs. Perinatal mortality rate was 47.9 deaths per 1000 total births in 2008 after introduction of the audits compared to 52.8 per 1,000 total births in 2007. CONCLUSION: Conducting routine perinatal audits is feasible and contributes to reduction of facility perinatal mortality rate.

RESUMO

BACKGROUND: Oxidative stress plays a role in the aetiology of pre-eclampsia and vitamin C may prevent pre-eclampsia. OBJECTIVE: To determine the association between plasma vitamin C and pre-eclampsia in Mulago Hospital, Kampala, Uganda. METHODS: This case-control study was conducted at Mulago Hospital from 1(st) May 2008 to 1(st) May 2009; 207 women were the cases and 352 women were the controls. Plasma vitamin C was assayed in the women using a colorimetric method. An independent t test was used to find the difference in the means of plasma vitamin C and logistic regression was used to find the association between plasma vitamin C and pre-eclampsia. RESULTS: The mean plasma vitamin C was 1.7(SD=0.7) × 10(3) µg/L in women with pre-eclampsia and 1.9(SD=0.7) × 10(3) µg/L in women with normal pregnancy (P=0.005). Women with low plasma vitamin C were at an increased risk of pre-eclampsia (OR 2.91, 95% CI: 1.56-5.44). CONCLUSION: There was a strong association between low plasma vitamin C, and pre-eclampsia in women attending antenatal clinics at Mulago Hospital, Kampala. Health workers need to advise women at risk in the antenatal period about diet, especially foods which are rich in vitamin C to probably reduce pre-eclampsia.

RESUMO

To describe the infant feeding practices in the general population in Uganda; and to assess the impact of maternal HIV status on these practices; a questionnaire was administered to women attending the follow-up clinics for child vaccination. Among the mothers who were still breastfeeding at the time of interview (N=838); 61.4of the HIV-infected women had planned to breastfeed for a maximum of 6 months; compared with 12.1of the HIV-uninfected women (p0.001). Among the women who were not breastfeeding at the time of interview (Nof the HIV-infected women had stopped breastfeeding within 3 months; compared with 23.5of the HIV-uninfected women (p0.001). Only 2.1of HIV-infected women seen up to 14 weeks postnatally practised mixed feeding; compared with 23.6of HIV-uninfected women (p0.001). After 6 months; however; 30of the HIV-infected women and 55of the HIV-uninfected mothers were using mixed feeding; with no significant differences. Programmes for the prevention of motherto- child transmission of HIV should re-enforce counselling activities to address the issue of early weaning by HIV-infected women; and to support safe breastfeeding up to 6 months

RESUMO

BACKGROUND: To report the experience of health workers who had played key roles in the early stages of implementing the prevention of mother-to-child HIV transmission services (PMTCT) in Uganda. METHODS: Interviews were conducted with 15 key informants including counsellors, obstetricians and PMTCT coordinators at the five PMTCT test sites in Uganda to investigate the benefits, challenges and sustainability of the PMTCT programme. Audio-taped interviews were held with each informant between January and June 2003. These were transcribed verbatim and manually analysed using the framework approach. RESULTS: The perceived benefits reported by informants were improvement of general obstetric care, provision of antiretroviral prophylaxis for HIV-positive mothers, staff training and community awareness. The main challenges lay in the reluctance of women to be tested for HIV, incomplete follow-up of participants, non-disclosure of HIV status and difficulties with infant feeding for HIV-positive mothers. Key informants thought that the programme's sustainability depended on maintaining staff morale and numbers, on improving services and providing more resources, particularly antiretroviral therapy for the HIV-positive women and their families. CONCLUSION: Uganda's experience in piloting the PMTCT programme reflected the many challenges faced by health workers. Potentially resource-sparing strategies such as the 'opt-out' approach to HIV testing required further evaluation.

RESUMO

AIM: To elucidate the immediate maternal thermal skin response when placing the neonate on the mothers' chest, skin-to-skin (STS). METHODS: Ugandan mothers with non-asphyxiated newborns after vaginal delivery (n = 39) were studied. Maternal skin and axillary temperatures were measured immediately before STS contact, then every 2 min for 20 min and finally 10 min after removing the neonate. Neonatal axillary/forehead temperatures were measured immediately before STS contact, and twice after initiating STS, followed by a measurement 10 min after the newborn had been removed. RESULTS: A rapid thermal response was demonstrated in maternal breast skin immediately after STS contact. It rose by 0.5 degrees C (p < 0.0001) on average the first 2 min after STS contact and fell by 0.5 degrees C 10 min after we had removed the neonate (p < 0.0001). Maternal axillary temperature also rose 2 min after initiation of STS (p < 0.0001) but stayed constant 10 min after removal of the newborn from the STS position. CONCLUSION: The findings indicate that there is a rapid maternal, thermal response to the positioning of the newborn STS. The tactile contact may elicit a maternal adaptation enhancing the warming of the newborn. Possible mechanisms include maternal autonomic nerve-mediated skin vasodilatation.

RESUMO

To identify factors that may limit acceptance of HIV testing and enrolment in the programmes for the prevention of mother-to-child-transmission of HIV, we retrospectively assessed the performance of the service at St Francis Hospital, Nsambya in Kampala. Over five years, a total of 26,556 pregnant women were offered voluntary counselling and confidential HIV testing and, if HIV positive, enrolment in the programme. Acceptance of the HIV test increased in the last two years (from 72.7% in 2001-2002 to 79.9% in 2003-2004). Enrolment in the programme increased over time and was greater among older (64% in women older than 30 years and 44.8% in those aged less than 20 years) and highly educated women. HIV prevalence was associated with age and inversely associated with the level of education. The need for specific personnel for counselling, male partners' involvement and availability of antiretroviral drugs for those who needed treatment were identified as factors possibly affecting implementation.

RESUMO

To study the effect of HIV infection on quality of life (QOL) during pregnancy and puerperium, QOL was measured in a cohort study at St. Francis Hospital Nsambya, Kampala, Uganda. Dartmouth COOP charts were administered to 132 HIV-positive and 399 HIV-negative women at 36 weeks of pregnancy and six weeks post-partum. Responses were coded from 0 = best health-status to 4 = worst health-status and scores of 3-4 defined as poor. Odds ratios (OR) (95% confidence intervals(CI)) for poor scores were calculated and independent predictors of poor QOL examined using logistic regression. In pregnancy, HIV-positive women were more likely to have poor scores in feelings: OR = 3.2(1.9-5.3), daily activities: OR = 2.8(1.4-5.5), pain: OR = 2.1(1.3-3.5), overall health: OR = 1.7(1.1-2.7) and QOL: OR = 7.2(3.6-14.7), all p= 0.2). HIV infection was independently associated with poor QOL: OR = 8.5(3.8-19). Findings in puerperium were similar to those in pregnancy except more HIV-positive women had poor scores in social activities: OR = 2.5(1.4-4.7) and change in health: OR = 5.4(2-14.5) and infant death also predicted poor QOL: OR = 6.7(2.4-18.5). The findings reflect HIV's adverse impact on maternal QOL and the need for interventions to alleviate this infection's social and emotional effects.

RESUMO

BACKGROUND: Peripartum antiretroviral regimens have been shown to prevent mother-to-child transmission of HIV (MTCT) in randomized clinical trials; however, direct comparison of published results is impossible given methodological and population differences. OBJECTIVE: To directly compare the efficacy of different antiretroviral regimens in reducing the risk of 6-week MTCT rate in African breastfeeding populations. METHODS: Pooled analysis including all mother-infant pairs from any relevant trial: West African ZDV-placebo trials, Petra ZDV+3TC [two regimens A (pre/intra/post-partum) and B (intra/post-partum), placebo from Uganda and Tanzania], SAINT (NVP and Petra arm B), HIVNET012 (NVP, ultra short ZDV pp) and the Vitamin A trial (as placebo arm in South Africa). Peripartum HIV infection was any positive RNA or DNA polymerase chain reaction test < day 60. The MTCT risk was estimated at 6 weeks for each treatment arm and compared with placebo or single-dose NVP using logistic regression adjusting for maternal CD4 cell count, breastfeeding and birthweight. RESULTS: Overall, 4125 singleton live-births were included; 3629 (88%) were assessed for HIV status at 6 weeks of age. In comparison with placebo, zidovudine + lamivudine (ZDV+3TC) arm A [adjusted odds ratio (AOR), 0.23; P < 0.0001], ZDV+3TC arm B (AOR, 0.49; P < 0.001), antenatal ZDV short (AOR, 0.55; P = 0.006) and nevirapine (NVP) (AOR, 0.60; P = 0.0007) significantly reduced MTCT. In comparison with NVP, only the longest regimen of ZDV+3TC (AOR, 0.39, P < 0.0005) was significantly more effective. CONCLUSION: These results are in line with current World Health Organisation guidelines suggesting equivalence of choice between single-dose NVP and short-course ZDV, and confirm the greater efficacy of ZDV+3TC than with any single antiretroviral drug.

RESUMO

A case controlled study about HIV seroprevalence among women with post-partum endometritis-myometritis (PPEM) matched with two controls. Each was performed in a non-governmental organization hospital in Kampala, Uganda. All participants were offered HIV pre- and post-test counselling. Personal and clinical information was obtained and HIV-1 ELISA tests performed on blood samples and discordant results resolved by Western blot test. HIV-1 seroprevalence was significantly higher among women with PPEM than controls, 26 (42.3%) and 26 (21.3%) respectively (P = 0.002). Women with PPEM were two-and-a-half times more likely to be HIV-positive than controls, odds ratio 2.74 (95% CI 1.34-5.65). Single or cohabiting women and low salaried women were also significantly more among PPEM cases than controls. In conclusion, PPEM cases had significantly higher seroprevalence of HIV-1 infection than controls and this needs further elucidation for purposes of management strategies.

RESUMO

In 1998, the ob/gyn associations of Uganda and Canada launched, under the umbrella of the FIGO Save the Mothers Initiative, a district-wide intervention which aimed to increase the availability and utilization of emergency obstetric care (EmOC) services in a rural district of Uganda. The article describes the experience of two professional ob/gyn associations in the development, implementation, monitoring and evaluation of the project. Preliminary results after 24 months of intervention indicate important gains in the capacity of health professionals to deliver EmOC, the availability of emergency transportation services and met need for EmOC.

RESUMO

The objective was to explore if HIV-1 infection is a risk factor for post-abortion endometritis-myometritis (PAEM) in an urban hospital in Kampala, Uganda. HIV-1 seroprevalence in women with and without post-abortion infection was established using two standard enzyme-linked immunosorbent assays. Fifty-two women with PAEM and 106 without PAEM infection were recruited. The HIV-1 seroprevalence was 17 (32.7%) among women with PAEM and 38 (36.5%) among women without post-abortion infection. HIV infection was not found to correlate with the risk for PAEM. HIV-1 seroprevalence in both groups was double that among antenatal clients in the same hospital, 14.6% in 1997. Life-threatening infections such as septicaemia, peritonitis and pelvic abscesses were observed among 12 cases (23%). HIV-1 infection was not shown to be a risk factor for PAEM, but women with abortions with and without PAEM have a higher prevalence of HIV-1 than antenatal clients.

RESUMO

BACKGROUND: Genital cancers in Uganda have been the most frequently diagnosed cancer in men as well as in women since the 1950s. Genetic studies have detected HPV-16 variants of Af1 class and identified a new sub-class designated Af1-u. OBJECTIVES: The main goal of this study is to analyze the prevalence of HPV strains and HPV variants in anogenital lesions of Ugandan male and female subjects in order to possibly determine their role in the pathogenesis of such lesions and to develop an Ugandan preventive HPV vaccine program. STUDY DESIGN: The study is planning to enroll male and female subjects affected by genital lesions, in particular to collect 200 scrapes/biopsies from women with normal ectocervical epithelium as well as with all different degrees of ectocervical lesions (from CIN 1/LSIL to cervical carcinoma). All samples are analyzed by PCR amplification of the L1 conserved region (nt 6584-7035) and the E6/E7 genes (nt 34-880), nucleotide sequence analysis, homology and phylogenetic studies. Variant distribution studies will be followed by serological studies of prevalence and incidence in 1000 women. PRELIMINARY RESULTS AND CONCLUSIONS: Penile cancers from the Kyadondo County have been analyzed for the presence of HPV sequences. More recently 16 ectocervical scrapes and three biopsies have been received from women attending the Nsambya Hospital and analyzed for the presence and type of HPVs. Our results, obtained by PCR and sequencing analysis, allowed the identification of HPV-16 Af1 sequences in 100% of tumor tissue and in 6.25% of scrapes. HPV 45 was identified only in one tumor together with HPV 16 infection. HPV 33 and HPV 58 were present in 20% and 40%, respectively of HPV positive benign samples. The results are showing a narrowing of the HPV pattern in more advanced lesions, suggesting that mainly HPV-16 Af1 patients are progressing to cancer.

RESUMO

A cross-sectional study of pregnant women was conducted at Nsambya Hospital in Kampala, to investigate the prevalence and effect of Plasmodium falciparum infections during pregnancy, in a peri-urban/urban location. Overall, 544 pregnant women were recruited when they presented at the labour ward for delivery. After giving informed consent, each subject answered a questionnaire and underwent a physical examination, and peripheral-blood samples were obtained. After each uncomplicated delivery, samples of placental and cord blood were obtained from the placenta and infant, respectively, and infant birthweights were recorded. Smears were prepared from the blood samples and checked for parasites. Only 46 and 36 of the 537 women investigated were positive for P. falciparum infection in their peripheral and placental blood, respectively. Plasmodium falciparum was the only parasite encountered. The prevalences of low birthweight and maternal parasitaemia and the intensities of maternal infection were each greater in primigravidae than secundi- or multi-gravidae. Despite the low prevalence of parasitaemia in this population, P. falciparum infection in the primigravidae was a significant contributor to their ill health, leading to low birthweights in their infants.

RESUMO

BACKGROUND: White homosexual men with human immunodeficiency virus (HIV) show progressive impairment of intestinal function assessed in terms of intestinal permeability and absorptive capacity. In this study we aimed to determine the effects of heterosexually acquired HIV on small-intestinal function in native Africans, among whom there is a high prevalence of tropical enteropathy. METHODS: Intestinal absorptive capacity (using 3-O-methyl-D-glucose, D-xylose, and L-rhamnose) and permeability (differential 5-h urinary excretion of lactulose/L-rhamnose) were assessed in healthy white (n = 57) and black (n = 14) controls in London, apparently healthy black Africans in Kampala, Uganda (n = 26), HIV-infected patients with (n = 9) and without (n = 30) diarrhoea in Kampala, and 39 white homosexual men with HIV in London who were stratified to resemble the African patient group. RESULTS: Intestinal integrity and absorptive capacity were significantly (P < 0.01) impaired in both black controls in London and apparently healthy black Africans, compared with white controls. HIV-infected white and black patients without diarrhoea did not differ significantly from white and black African controls, respectively, with the exception of increased intestinal permeability among the white patients. White and black African patients with HIV/acquired immunodeficiency syndrome (AIDS) and diarrhoea were found to have marked malabsorption and increased intestinal permeability. Although the relative increase in intestinal permeability was similar in the two groups, by far the largest values for intestinal permeability were found among black Africans with HIV/AIDS and diarrhoea. CONCLUSIONS: Whites and blacks differ with regard to intestinal barrier function. HIV-positive black Africans without gastrointestinal symptoms differ insignificantly from white Londoners with homosexually acquired disease, whereas those with gastrointestinal symptoms have markedly abnormal indices of small-intestinal function with severely comprised intestinal integrity.

RESUMO

We studied the seroprevalence and transmission of Kaposi's sarcoma-associated herpesvirus (KSHV/HHV8), among 215 Ugandan children, adolescents and young adults. We measured antibodies to a latent nuclear antigen (LANA) and a lytic cycle protein encoded by open reading frame (orf) 65. Infection with KSHV/HHV8 occurred during early childhood and reached adult levels (approx. 50%) before the age of puberty. In children younger than 12 years of age, antibodies to LANA and the orf65 protein were independently associated with hepatitis B infection (p < 0.005). KSHV/HHV8 infection was not associated with antibodies to hepatitis A virus and hepatitis C virus, nor with the quality of the water supply, household size, previous blood transfusions, number of boy/girl friends or marital status. Antibodies to the orf65 protein, but not LANA, were weakly associated with a history of i.v. injections. Our results show that, in contrast to its sexual mode of transmission among homo/bisexual men and sexually transmitted diseases clinic attendees of Northern Europe and the US, transmission of KSHV in Uganda occurs largely before puberty. Among Ugandan children, KSHV transmission follows a horizontal pattern similar to other herpesviruses, in particular the related gamma herpesvirus, Epstein-Barr virus. Transmission of KSHV may be facilitated by living conditions that also promote infection with hepatitis B virus.

RESUMO

The presence of several infections was determined in tissue and serum samples from 34 cases and 23 controls seen in 1984-85 at Mulago Hospital in Kampala, Uganda. When assessing single infections, association with cervical cancer could be shown for 5 agents, namely by Southern blot assay for human papillomavirus types 16 and 18 (HPV), and by serological tests at varying levels of antibody titres, for herpes simplex virus type I and/or 2 (HSV), cytomegalovirus (CMV), Epstein-Barr virus, viral capsid antigen (EBV-VCA), and Chlamydia trachomatis (CLT). Due to interaction, HSV and CMV were associated with cervical cancer only when infection by both of these agents was demonstrable. In the assessment of the simultaneous presence of these 5 infections, moderately high antibody titres were taken as the cut-off point for infection by HSV, CMV, EBV-VCA, and CLT. This showed that 3 and 4 infections at a time were seen in the majority of the cases in contrast to the controls with essentially no more than 2 such infections. A linear trend in the rise of risk for cervical cancer was noted with increasing number of infections.
