Acceptability of study procedures (self-collected introital swabs, blood draws and stool sample collection) by students 10-16 years for an HPV vaccine effectiveness study: a pilot study.

BACKGROUND: A cohort study was planned to evaluate vaccine immunogenicity and effect of malaria and helminth co-infections on the bivalent Human papilloma virus (HPV) vaccine. The study would involve self collected introital swabs, blood draws and stool sample collection. We therefore conducted a pilot study to assess the acceptability of these procedures among the students and their parents. RESULTS: A cross-sectional study among forty four students from two purposively selected primary schools of Western Uganda. Exit interviews and two focus group discussions (FGD) (for parents) were conducted. Acceptability was measured by willingness to undergo the procedures again, recommending the procedures to others as well as proportion of introital swabs positive for ß globulin. FGD determined acceptability of the parents and explored opinions and perceptions that would influence their decisions. HPV-16/18 and ß globulin deoxyribonucleic acid (DNA) were analysed using a polymerase chain reaction (PCR) kit. All the students (100%) in the study were willing to provide a self- collected introital swab and a stool sample as well as recommending their friends while (86.3%) were willing for blood draws. There were 40/44 (90.1%) self collected introital swabs that had positive result for human ß globulin though none of them was positive for HPV-16/18. In the FGD, it emerged that parents concerns were on the blood draws and introital swab collection which were addressed. CONCLUSIONS: The study procedures were highly acceptable among this study population of students and their parents. Follow-up to assess HPV vaccine effectiveness and factors that may influence the vaccine in this age group is feasible.

Effect of subsequent pregnancies on HIV disease progression among women in the Mulago Hospital MTCT-Plus program in Uganda.

OBJECTIVE: To investigate the effect of subsequent pregnancies on HIV disease progression among HIV-infected women at Mulago Hospital, Uganda. METHODS: In a retrospective cohort study, data were analyzed from women enrolled in the Mother-To-Child Transmission Plus program from March 2003 to December 2011. The CD4 cell count, the development of new AIDS-defining opportunistic infections, and the AIDS-related mortality were compared between women with and without subsequent pregnancies. RESULTS: Overall, 409 women were enrolled and 195 (47.7%) had subsequent pregnancies. Antiretroviral therapy (ART) was initiated in 143 (73.3%) women with and 155 (72.4%) women without subsequent pregnancies. Kaplan-Meier analysis for women receiving ART showed no differences between women with and without subsequent pregnancies in the median times to clinical failure (62.7 vs 64.7 months; P=0.31), immunological failure (68.8 vs 75.5 months; P=0.10), and death (68.8 vs 75.5 months; P=0.53). In a Cox regression analysis, subsequent pregnancies were not associated with immunological failure during follow-up (adjusted hazard ratio 1.13, 95% confidence interval 0.06-2.09). CONCLUSION: Subsequent pregnancies could have no detrimental effect on HIV disease progression among HIV-infected women whose treatment is well managed.

Aerobic cervical bacteriology and antibiotic sensitivity patterns in patients with advanced cervical cancer before and after radiotherapy at a national referral hospital in Uganda.

OBJECTIVE: To determine prevalent aerobic cervical bacteria and sensitivity to commonly used antibiotics in patients with advanced cervical cancer before and after 4 weeks of external beam radiotherapy (EBRT). METHODS: Cervical swabs were collected prior to the initial radiation dose and after 4 weeks of radiotherapy at Mulago Hospital. Aerobic culture was performed on blood agar, chocolate agar, and MacConkey agar, and incubated at 35-37 ° for 24-48 hours. Isolates were identified using colonial morphology, Gram staining, and biochemical analysis. Sensitivity testing was performed via Kirby-Bauer disk diffusion and dilution. Differences in the proportions of bacteria isolated before and after radiotherapy were compared. Paired t test was used to obtain differences in sensitivity before and after radiotherapy. RESULTS: Normal flora increased significantly after EBRT (P=0.02). There was no significant change in overall proportion of positive cultures. Sensitivity to commonly used antibiotics improved (P=0.05) and resistance significantly decreased (P=0.005). Significant differences were seen mainly with ciprofloxacin, ceftriaxone, and gentamicin. CONCLUSION: Four weeks of EBRT did not sterilize the cervix but resulted in an increase in normal flora. Radiotherapy appeared to reduce resistance to commonly used antibiotics. Sensitivity to chloramphenicol was higher than for the more commonly used antibiotics.

Fetal demise and associated factors following umbilical cord prolapse in Mulago hospital, Uganda: a retrospective study.

BACKGROUND: Umbilical cord prolapse is an obstetric complication associated with high perinatal morbidity and mortality. A few interventions may improve fetal outcome. In developed countries these have advanced to giving intrauterine fetal resuscitation. Conditions in low resource settings do not allow for some of these advanced techniques. Putting the mother in knee chest position and immediate delivery may be the only options possible.We set out to determine the incidence of fetal demise and associated factors following umbilical cord prolapsed (UCP) in Mulago Hospital, Uganda. METHODS: In a retrospective study conducted in Mulago hospital, Uganda, file records of mothers who delivered between 1st January 2000 to 31st December 2009 and had pregnancies complicated by umbilical cord prolapse with live fetus were selected. We collected information on referral status, cord position, cervical dilatation, fetal heart state at the time of diagnosis of UCP, diagnosis to delivery interval, use of knee chest position, mode of delivery, birth weight and fetal outcome.We computed incidence of fetal demise following UCP and determined factors associated with fetal demise in pregnancies complicated by UCP. RESULTS: Of 438 cases with prolapsed cord, 101(23%) lost their babies within 24 hours after birth or were delivered dead. This gave annual cumulative incidence of fetal death following UCP of 23/1000 live UCP cases delivered /year.The major factors associated with fetal outcome in pregnancies complicated by UCP included; diagnosis to delivery interval <30 min, RR 0.79 (CI 0.74-0.85), mode of delivery, RR 1.14 (CI 1.02-1.28), knee chest position, RR 0.81 (CI 0.70-0.95). CONCLUSIONS: The annual cumulative incidence of fetal death in our study was 23/1000 live UCP cases delivery per year for the period of 10 years studied. Cesarean section reduced perinatal mortality by a factor of 2. Diagnosis to delivery interval <30 minutes and putting mother in knee chest position were protective against fetal death.

Acceptability of cervical cancer screening via visual inspection with acetic acid or Lugol's iodine at Mulago Hospital, Uganda.

OBJECTIVE: To assess acceptability of cervical cancer screening via visual inspection with acetic acid or Lugol's iodine (VIA/VILI) at Mulago Hospital, Uganda. METHODS: Exit interviews were conducted among women who had undergone opportunistic screening by VIA/VILI at 2 family planning clinics based within the hospital. Measures of acceptability were willingness to undergo the procedure in future if required and willingness to recommend the procedure to others. Focus group discussions were conducted to determine reasons for declining VIA/VILI. RESULTS: A total of 384 participants were recruited into the study. Of the 229 women who agreed to undergo screening by VIA/VILI, 209 (91.3%) were willing to recommend the service to other women, while 223 (97.4%) stated that they would undergo VIA/VILI again if the need arose. Education level showed a significant association with screening uptake (P=0.007). In all, 155 women declined screening. Reasons for refusal included fears about privacy, fear of pain or discomfort, and worry about the test results. CONCLUSION: Cervical cancer screening by VIA/VILI was rated highly acceptable among women who underwent the procedure. Women with a positive attitude toward screening could be trained as peer educators and community champions to improve uptake.

Urologic complications among women with advanced cervical cancer at a tertiary referral hospital in Uganda.

OBJECTIVE: To determine the prevalence of and factors associated with urologic complications among women with advanced cervical cancer before treatment in Uganda. METHODS: In total, 283 women with histologically confirmed stage IIB-IVB cervical cancer who were admitted to Mulago Hospital over a 6-month period were studied. Abdominopelvic scan was carried out to check for hydronephrosis and hydroureter and to measure the tumor volume. Serum creatinine and urea levels were measured, and the presence of anuria and vesicovaginal fistula (VVF) was ascertained from self-reporting and clinical records. RESULTS: Urologic complications were present in 138 (48.8%) women. Hydronephrosis, VVF, hydroureter, and anuria were present in 112 (39.6%), 21 (7.4%), 11 (3.9%), and 9 (3.2%) women, respectively; serum creatinine and urea levels were elevated in 48 (17.0%) women. Stage of disease was significantly associated with urologic complications: stage IIIB odds ratio (OR) 3.36 (95% confidence interval [CI], 1.57-7.20); stage IVA OR 17.10 (95% CI, 6.07-48.16); P<0.001. CONCLUSION: There is a high prevalence of urologic complications among women with advanced cervical cancer; these complications are significantly associated with the stage of cervical cancer.

Evaluation of 'see-see and treat' strategy and role of HIV on cervical cancer prevention in Uganda.

BACKGROUND: There is scant information on whether Human Immunodeficiency Virus (HIV) seropositivity has an influence on the outcome of treatment of precancerous cervical lesions using cryotherapy. We studied the prevalence of cervical abnormalities detectable by visual inspection and cervical lesions diagnosed by colposcopy according to HIV serostatus and described the outcomes of cryotherapy treatment. METHODS: Trained nurses examined women not previously screened for cervical cancer using visual inspection with acetic acid (VIA) and Lugol's iodine (VILI) in two family planning/post natal clinics in Kampala, Uganda, from February 2007 to August 2008. Women with abnormal visual inspection findings were referred for colposcopic evaluation and HIV testing. Women with precancerous cervical lesions detected at colposcopy were treated mainly by cryotherapy, and were evaluated for treatment outcome after 3 months by a second colposcopy. RESULTS: Of the 5 105 women screened, 834 presented a positive screening test and were referred for colposcopy. Of these 625 (75%) returned for the colposcopic evaluation and were tested for HIV. For the 608 (97.5%) women in the age range 20-60 years, colposcopy revealed 169 women with cervical lesions: 128 had inflammation, 19 had low grade squamous intraepithelial lesion (LGSIL), 13 had high grade squamous intraepithelial lesion (HGSIL), 9 had invasive cervical cancer and 2 had inconclusive findings. Detection rates per 1 000 women screened were higher among the older women (41-60 years) compared to women aged 20-40 years. They were accordingly 55% and 20% for inflammation, 10% and 2% for LGSIL, 5% and 2% for HGSIL, 6% and 1% for invasive cervical cancer.Of the 608 women, 103 (16%) were HIV positive. HIV positivity was associated with higher likelihood of inflammation (RR = 1.7; 95% CI: 1.2-2.4). CONCLUSIONS: Detection rates were higher among older women 41-60 years. Visual inspection of the cervix uteri with acetic acid (VIA) and Lugol's iodine (VILI) used as a sole method for cervical cancer screening would entail significant false positive results. HIV seropositivity was associated with a higher prevalence of inflammatory cervical lesions. In view of the small numbers and the relatively short follow up time of 3 months, we could not make an emphatic conclusion about the effect of HIV serostatus on cryotherapy treatment outcome.

Access to HIV/AIDS care for mothers and children in sub-Saharan Africa: adherence to the postnatal PMTCT program.

Despite scale up of perinatal prevention of mother-to-child transmission (PMTCT) of HIV interventions, postnatal continuity of comprehensive HIV/AIDS care, for both the mother and baby, remains a challenge in developing countries. We determined adherence to the postnatal PMTCT program (PN-PMTCT) and the associated factors among mothers at a public urban hospital in Uganda. We interviewed HIV-positive postnatal mothers on discharge and we determined adherence to PN-PMTCT by the proportion of mothers that honored their return appointments by the end of eight weeks postpartum. We had focus group discussions to assess factors that influence adherence to PN-PMTCT. Of 289 mothers, only 110 (38%) adhered to PN-PMTCT. Previous attendance of a routine postnatal review and having access to a phone were significantly associated with adherence to PMTCT among mothers older than 25 years (odds ratio (OR) 3.6 (95% confidence interval (CI); 1.2-10.4)) and (OR 3.1 (95% CI; 1.3-7.1)), respectively. On the other hand, Christianity (OR 3.2 (95% CI; 1.1-9.0)) was significantly associated with adherence to PN-PMTCT among mothers below 25 years of age. Mothers' perceived benefits of the PN-PMTCT program, easy access to the program, and presence of social support from a spouse were important motivators for mothers to adhere to PN-PMTCT. Even with improved antenatal and intra-partum PMTCT services, only a third of the HIV-infected mothers adhered to the PN-PMTCT program. Mothers who previously attended a routine postnatal care were 3.6 fold more likely to adhere to PN-PMTCT. We recommend strategies to increase mothers' adherence to PN-PMTCT interventions in order to increase access to HIV/AIDS care for mothers and children in sub-Saharan Africa.

Male partner involvement in reducing loss to follow-up after cervical cancer screening in Uganda.

OBJECTIVE: To evaluate the efficacy of male partner involvement in reducing loss to follow-up among women in Uganda referred for colposcopy after a positive cervical cancer-screening test. METHODS: In 2 family-planning/postnatal clinics at Mulago Hospital, Kampala, Uganda, 5094 women were screened for cervical lesions. Those who screened positive were referred for colposcopy; half were allocated to the intervention group and half to the control group. In the intervention group, information about the screening findings and a request to assist their partner in attending the next examination were sent to male partners. In the control group, a standard service was provided, which did not include a letter to the male partner. Logistic regression models were applied to calculate the probability of women returning for colposcopy. RESULTS: Of the 834 women referred, 209 (25%) did not return for colposcopy: 143/419 (34%) from the control group and 66/415 (16%) from the intervention group. Women in the intervention group were more likely to return (odds ratio 2.8; 95% confidence interval, 1.9-3.9). CONCLUSION: Male partner involvement significantly reduced loss to follow-up among women referred for colposcopy.

A randomized clinical trial comparing safety, clinical and parasitological response to artemether-lumefantrine and chlorproguanil-dapsone in treatment of uncomplicated malaria in pregnancy in Mulago hospital, Uganda.

BACKGROUND: Malaria infection during pregnancy is a major public health problem. Due to increasing resistance to Chloroquine and Sulphadoxine/Pyrimethamine, the Ugandan national policy on malaria treatment was changed in 2005 to Artemisinin-based combination therapy (ACT) as the first-line treatment for uncomplicated malaria. The policy recommends assessment of safety and efficacy of alternative drugs for treatment of uncomplicated malaria. We compared the efficacy and safety of Artemether-Lumefantrine (Coartem) and Chlorproguanil-Dapsone (Lapdap) in the management of uncomplicated malaria in pregnancy. METHODOLOGY: We enrolled 110 pregnant women in the second and third trimester of pregnancy who presented to Mulago hospital, Uganda, with uncomplicated malaria. The study design was an open-label randomized clinical trial. Participants were randomized to receive either Artemether-Lumefantrine (Coartem 20 mg/120 mg) orally or Chlorproguanil-Dapsone (Lapdap) orally for 3 consecutive days. Primary endpoints were clinical and parasitological response assessed on days 0, 1, 2, 4, 7, 14 and 28. Adverse effects, clinical response (treatment failure) and parasitological response were compared. Analysis was by intention to treat. RESULTS: Of the 100 women who completed the study, there was no statistically significant difference in clinical and parasitological response by Day 4. The mean fever clearance time 3.0 days with Lapdap versus 2.5 days with Coartem was comparable. Likewise, mean parasite clearance time of 2.4 and 2.2 days for Lapdap and Coartem respectively was comparable. The adverse effects were comparable between the two groups. CONCLUSION: Artemether-Lumefantrine and Chlorproguanil-Dapsone have high and comparable cure rates and similar safety profiles when used for treatment of uncomplicated malaria in pregnancy.

Influences on uptake of reproductive health services in Nsangi community of Uganda and their implications for cervical cancer screening.

BACKGROUND: Cervical cancer is the most common female cancer in Uganda. Over 80% of women diagnosed or referred with cervical cancer in Mulago national referral and teaching hospital have advanced disease. Plans are underway for systematic screening programmes based on visual inspection, as Pap smear screening is not feasible for this low resource country. Effectiveness of population screening programmes requires high uptake and for cervical cancer, minimal loss to follow up. Uganda has poor indicators of reproductive health (RH) services uptake; 10% postnatal care attendance, 23% contraceptive prevalence, and 38% skilled attendance at delivery. For antenatal attendance, attendance to one visit is 90%, but less than 50% for completion of care, i.e. three or more visits. METHODS: We conducted a qualitative study using eight focus group discussions with a total of 82 participants (16 men, 46 women and 20 health workers). We aimed to better understand factors that influence usage of available reproductive health care services and how they would relate to cervical cancer screening, as well as identify feasible interventions to improve cervical cancer screening uptake. RESULTS: Barriers identified after framework analysis included ignorance about cervical cancer, cultural constructs/beliefs about the illness, economic factors, domestic gender power relations, alternative authoritative sources of reproductive health knowledge, and unfriendly health care services. We discuss how these findings may inform future planned screening programmes in the Ugandan context. CONCLUSION: Knowledge about cervical cancer among Ugandan women is very low. For an effective cervical cancer-screening programme, awareness about cervical cancer needs to be increased. Health planners need to note the power of the various authoritative sources of reproductive health knowledge such as paternal aunts (Sengas) and involve them in the awareness campaign. Cultural and economic issues dictate the perceived reluctance by men to participate in women's reproductive health issues; men in this community are, however, potential willing partners if appropriately informed. Health planners should address the loss of confidence in current health care units, as well as consider use of other cervical cancer screening delivery systems such as mobile clinics/camps.

Knowledge, attitudes and practices on cervical cancer screening among the medical workers of Mulago Hospital, Uganda.

BACKGROUND: Cervical cancer is the commonest cancer of women in Uganda. Over 80% of women diagnosed in Mulago national referral and teaching hospital, the biggest hospital in Uganda, have advanced disease. Pap smear screening, on opportunistic rather than systematic basis, is offered free in the gynaecological outpatients clinic and the postnatal/family planning clinics. Medical students in the third and final clerkships are expected to learn the techniques of screening. Objectives of this study were to describe knowledge on cervical cancer, attitudes and practices towards cervical cancer screening among the medical workers of Mulago hospital. METHODS: In a descriptive cross-sectional study, a weighted sample of 310 medical workers including nurses, doctors and final year medical students were interviewed using a self-administered questionnaire. We measured knowledge about cervical cancer: (risk factors, eligibility for screening and screening techniques), attitudes towards cervical cancer screening and practices regarding screening. RESULTS: Response rate was 92% (285). Of these, 93% considered cancer of the cervix a public health problem and knowledge about Pap smear was 83% among respondents. Less than 40% knew risk factors for cervical cancer, eligibility for and screening interval. Of the female respondents, 65% didn't feel susceptible to cervical cancer and 81% had never been screened. Of the male respondents, only 26% had partners who had ever been screened. Only 14% of the final year medical students felt skilled enough to use a vaginal speculum and 87% had never performed a pap smear. CONCLUSION: Despite knowledge of the gravity of cervical cancer and prevention by screening using a Pap smear, attitudes and practices towards screening were negative. The medical workers who should be responsible for opportunistic screening of women they care for are not keen on getting screened themselves. There is need to explain/understand the cause of these attitudes and practices and identify possible interventions to change them. Medical students leave medical school without adequate skills to be able to effectively screen women for cervical cancer wherever they go to practice. Medical students and nurses training curricula needs review to incorporate practical skills on cervical cancer screening.

Incidence of postcesarean infections in relation to HIV status in a setting with limited resources.

BACKGROUND: The aim of the present study was to assess the incidence of postcesarean infections in relation to HIV status in a setting where resources are limited, HIV infection is common, and antiretroviral treatment is not generally available. METHODS: The setting was a tertiary African obstetric unit with 27,000 deliveries annually. The study design was prospective and the sample consisted of 1600 of cesarean sections. All women requiring cesarean section were eligible for inclusion. HIV status was registered from the antenatal card only. For the analysis, the participants were divided into two categories: those with negative or unknown HIV status and those with positive HIV status. The main outcome measures are endometritis, wound infection, and mobilization parameters. RESULTS. A total of 1526 cases, of which 1492 were emergency cesarean sections, were included in the analysis. HIV status was negative or unknown in 1430 cases and positive in 96. In the HIV-negative/unknown group, the incidence of endometritis was 8.5% (121/1430), wound infection 5.0% (71/1430), and endometritis and/or wound infection 10.8% (154/1430). In the HIV-positive group, the corresponding incidences were 51.0% (49/96), 29.2% (28/96), and 65.5% (63/96), respectively. The indication for cesarean section was dystocia in 79% (134/170) of the women who developed endometritis. CONCLUSIONS: The results indicate that women with untreated HIV infection are at very high risk of postcesarean infection in low-resourced settings.
