Prevalence and risk factors for diabetic foot complications among people living with diabetes in Harare, Zimbabwe: a cross-sectional study

BackgroundDiabetic foot disease (DF) is a common diabetes-related complication; however, the prevalence and associated risk factors for DF are not well characterised among people living with diabetes (PLWD) in Zimbabwe. This may suggest the unavailability of adequate strategies to diagnose and treat DF in the country. This study aimed to determine the prevalence of DF and associated risk factors for PLWD in Harare, Zimbabwe.MethodsThis was a cross-sectional study, employing a quantitative approach. In total, 352 PLWD were recruited from 16 primary care clinics in Harare. Sociodemographic and clinical data were collected via face-to-face interviews and clinical records reviews. The DF screening included an evaluation for peripheral neuropathy, ankle-brachial index (ABI), ulceration, and amputation. Self-administered questionnaires were used to assess knowledge, attitudes, and practices (KAPs), and KAP was scored using Bloom’s cut-off. Chi-Square goodness-of-fit tests were performed, and regression analyses were used for association analysis. The threshold for significance was p < 0.05.ResultsThis group included 82 men and 279 women, with a combined mean age of 57.9 ± 14 years. Twenty one (~ 26%) men and 41 (15%) women had type 1 diabetes. The diabetes type distribution significantly differed by gender (p < 0.001). Oral hypoglycaemics (71%) were most commonly administered for management. DF was observed in 53% (95% CI = 50–56) of PLWD. Other DF symptoms observed were abnormal ABI (53%), peripheral neuropathy (53%), foot ulceration (17%) and amputation (3%). Peripheral neuropathy increased the risk of ulceration (OR = 1.7; 95% CI = 1.1–2.6; p = 0.019), while insulin use was protective against amputation (OR = 0.1; 95% CI = 0.1–0.9; p = 0.049). Most (87%) of the participants demonstrated good DF knowledge and the importance of adhering to medication to prevent DF. However, 96% did not know that smoking was a risk factor for DF. Nearly two-thirds (63%) demonstrated poor attitudes and practices. Poor attitudes and practices were not predictors of DF ulceration risk (p > 0.05).ConclusionThis study showed that there was a high prevalence of DF (53%) in PLWD in Zimbabwe, and insulin use was protective against DF. There is an urgent need for policy revisions to include foot screening in routine primary care and increasing insulin use for PLWD to prevent complications such as DF as an integral part of primary care.

Effect of a brief psychological intervention for common mental disorders on HIV viral suppression: A non-randomised controlled study of the Friendship Bench in Zimbabwe.

For people living with co-morbid HIV and common mental disorders (CMD), it is not known whether a brief psychological intervention for CMD can improve HIV viral suppression. We conducted a prospective cohort study in eight primary care clinics in Harare, Zimbabwe, enrolling adults with co-morbid HIV and CMD. Six clinics provided the Friendship Bench (FB), a brief psychological intervention for CMD based on problem-solving therapy, delivered by lay counsellors. Two clinics provided enhanced usual care (EUC). The primary outcome was viral non-suppression after six months (viral load ≥400 copies/mL). Data were analysed using a difference-in-difference approach with linear regression of cluster-level proportions, adjusted for baseline viral non-suppression (aDiD). The secondary outcome was presence of CMD measured by the Shona Symptom Questionnaire. In FB clinics, 407/500 (81.4%) participants had viral load results at baseline and endline: 58 (14.3%) had viral non-suppression at baseline and 41 (10.1%) at endline. In EUC clinics, 172/200 (86.0%) had viral load results at baseline and endline: 22 (12.8%) were non-suppressed at baseline and 26 (15.1%) at endline (aDiD = -7.3%; 95%CI 14.7% to -0.01%; p = 0.05). Of the 499 participants virally suppressed at baseline, the FB group had lower prevalence of non-suppression at endline compared to the EUC group (2.9% vs 9.3%; p = 0.002). There was no evidence of a difference in endline viral non-suppression by group among the 80 participants with non-suppression at baseline (53.5% vs 54.6%; p = 0.93). The FB group was less likely to screen positive for CMD at endline than the EUC group (aDiD = -21.6%; 95%CI -36.5% to -6.7%; p = 0.008). People living with co-morbid HIV and CMD may benefit from receiving a low-cost mental health intervention to enhance viral suppression, especially if they are already virally suppressed. Research is needed to understand if additional adherence counselling could further improve viral suppression.

The effect of a comprehensive typhoid conjugate vaccine campaign on antimicrobial prescribing in children in Harare, Zimbabwe: a mixed methods study

Vaccines prevent infections and could subsequently reduce antimicrobial use. A 1-week mass vaccination campaign was done with Typbar-TCV (Bharat Biotech, Hyderabad, India) between Feb 25 and March 4, 2019. We investigated whether this typhoid conjugate vaccine campaign could affect antimicrobial prescribing in children presenting to primary care in Harare, Zimbabwe. In this mixed methods study, data for acute paediatric outpatient consultations between Jan 1, 2018, and March 31, 2020, were collected from five clinics in Harare. Interrupted time series analysis was done to compare prescription data before and after the campaign. To contextualise findings, qualitative data were collected between April 20, 2021, and July 20, 2022, comprising ethnographic research (ie, workshops, surveys, observations, and interviews) in 14 clinics. Ethnographic data were used for thematic analysis. The primary outcome was monthly antimicrobial prescriptions in children aged 6 months to 15 years, normalised by the number of trauma events in all age groups. In the data collection period, 27 107 paediatric consultations were recorded. 17 951 (66·2%) of 27 107 children were prescribed antimicrobials. Despite the perceived reduction in typhoid cases and a decreasing trend in the prescription of antimicrobials commonly used to treat typhoid (ie, ciprofloxacin and azithromycin), mass vaccination with Typbar-TCV did not affect the total rate of antimicrobials (adjusted rate ratio, 1·20, 95% CI 0·70-2·05, p=0·51) or the rate of typhoid antimicrobials prescribed (0·93, 0·44-1·96, p=0·85). Unsafe water sources and insufficient diagnostic services were reported to contribute to the continued disease burden and antimicrobial prescription. Non-specific febrile illness caused by confirmed or suspected typhoid is a common cause of antimicrobial use in endemic areas. Although effective in preventing typhoid fever, we were unable to identify any effect of Typbar-TCV on antimicrobial prescribing. Ethnographic research showed the effect of contextual factors on antimicrobial prescribing, including concerns regarding safe water access, appropriate sewage disposal, health-care and diagnostic availability. To realise effects beyond disease burden reduction, holistic approaches addressing these concerns are needed so that the value of vaccines mitigating the effects of antimicrobial use as a driver of antimicrobial resistance is fully achieved.

High satisfaction among patients at HIV clinics in Harare, Zimbabwe: a time and motion evaluation and patient satisfaction study.

Patient satisfaction is an important component of health and healthcare utilization, which measures the perceived needs and expectations for healthcare services. Patient satisfaction surveys are effective in improving health outcomes by informing health facilities on service and provider gaps and guiding the development of effective action plans and policies for quality improvement within a healthcare organization. Although patient satisfaction and patient flow analyses have been conducted in Zimbabwe, the combination of these two quality improvement measures in the context of Human Immunodeficiency Virus (HIV) clinics has not previously been evaluated. This study assessed and evaluated patient flow and patient satisfaction to enhance care quality and improve HIV service delivery to optimize patient health. We collected time and motion data from HIV patients who attended three purposively selected City of Harare Polyclinics in Harare, Zimbabwe. All patients who sought care at the clinic were given time and motion forms to track their movement and the time spent at each service area. After services were completed, patients were invited to participate in a satisfaction survey regarding their services and care. The average waiting time from clinic arrival to see the provider was 2 hr and 14 min. The areas with the longest waiting time and bottlenecks occurred at registration (49 min) and the HIV clinic waiting area (44 min). Despite these extended times, the overall patient satisfaction for HIV services was high at 72%, with over half (59%) reporting that there was nothing they did not like about their services. Patients were most satisfied with services provided (34%), timely service (27%), and antiretroviral medications (19%). The areas of least satisfaction were related to time delays (24%) and cashier delays (6%). Despite prolonged waiting times, patients' overall satisfaction with their clinic experience remains high. Perceptions of satisfaction are influenced by experience, culture, and context. However, there are still several areas of recommendations to improve service, care, and quality. Specifically, reducing or eliminating service fees, increasing clinic hour times, and having available medication were most cited. Support from the Zimbabwe Ministry of Health and Child Care, City of Harare, and other decision-makers is needed to improve patient satisfaction and address patients' recommendations within the City of Harare Polyclinic organization in accordance with the 2016-20 National Health Strategies for Zimbabwe.

Effects of Gender and Baseline CD4 Count on Post-Treatment CD4 Count Recovery and Outcomes in Patients with Advanced HIV Disease: A Retrospective Cohort Study.

Presentation to care with advanced HIV disease (AHD) is a significant problem in sub-Saharan Africa. We evaluated factors associated with immune recovery among individuals presenting to care with AHD in Zimbabwe. We conducted a retrospective evaluation of outcomes among adult (>18 years old) individuals with AHD (CD4 count ≤200 cells/mm3) receiving care at 18 outpatient primary care clinics in Harare, Zimbabwe. Baseline and 12-month CD4 count data were extracted from medical records. CD4 count recovery (defined as CD4 count >200 cells/mm3) after 12 months on non-nucleotide reverse transcriptase inhibitor (NNRTI)-based antiretroviral therapy (ART) regimen was determined and factors associated with CD4 count recovery were established using logistic regression. All statistical analysis was performed on SPSS v23. A total of 1,338 participant records were included in the analysis. The median interquartile range (IQR) age was 37 (30-43) years and 52% were females. The baseline median (IQR) CD4 count was 50 (28-75) cells/mm3 and was significantly lower among patients with history of cryptococcal meningitis compared to those without [25 (10-52) vs. 52 (32-77), respectively; p = .0009]. The median (IQR) CD4 count at 12 months after ART initiation increased from 50 (28-75) at baseline to 180 (92-290) cells/mm3. Immune recovery with a CD4 count >200 cells/mm3 was observed in 181/417 (43%). Male gender and low baseline CD4 count were strong predictors of poor immunological recovery on ART. Immunological recovery following ART initiation was 43% among individuals with AHD. Male patients are most vulnerable to persistent immunological failure.

Abstract A118: Uptake of cervical cancer screening services in urban Zimbabwe: Healthcare provider perspectives

Abstract Background: In sub-Saharan Africa, Zimbabwe is among the top 6 countries with the highest cervical cancer incidence and mortality rates. Despite the disproportionate and growing burden, uptake of cervical cancer screening remains low. Little is known about the perceptions of healthcare providers who play a vital role in the provision and implementation of cervical cancer screening. This study explores healthcare provider perceptions of the factors that influence the uptake of cervical cancer screening in Zimbabwe. Methods: One-on-one in-depth interviews were conducted with healthcare providers currently or previously involved in cervical cancer prevention programs at select hospitals and clinics in Harare and Chinhoyi – two urban cities in Zimbabwe. A deductive thematic approach was used to analyze qualitative data to understand factors influencing the provision and uptake of cervical cancer screening. Results: We conducted 21 interviews with healthcare providers working in cervical cancer prevention for an average of 4 years. Three main themes related to the provision of cervical cancer screening were funding availability through donor support, demand of screening services, and availability of technical and human resources. Experiencing symptoms and no-cost screening services were perceived as facilitators for uptake of cervical cancer screening, while lack of adequate health education about cervical cancer and misconceptions about the screening procedure and outcomes were perceived as barriers to uptake of screening. Majority of the providers recommended increased sensitization and health education through various platforms; outreach initiatives; and training of more healthcare providers to conduct cervical cancer screening. Conclusion: This study contributes to a holistic understanding and identification of intervention points to effectively increase uptake of cervical cancer screening. Multi-level strategies promoting awareness of cervical cancer screening and strengthening healthcare systems may contribute significantly to increasing cervical cancer screening rates which in turn will lead to reducing the burden of cervical cancer in Zimbabwe.

Clinical and bacteriological outcomes in patients with urinary tract infections presenting to primary care in Harare, Zimbabwe: a cohort study.

Background: Treatment for urinary tract infections (UTIs) is usually empiric and is based on local antimicrobial resistance data. These data, however, are scarce in low-resource settings. The aim of this study is to determine the impact of antibiotic treatment on clinical and bacteriological outcomes in patients presenting with UTI symptoms to primary care in Harare. Methods: This cohort study enrolled participants presenting with UTI symptoms to 10 primary healthcare clinics in Harare between July 2019 and July 2020. A questionnaire was administered and a urine sample was collected for culture. If the urine culture showed growth of ≥10 5 colony forming units/mL of a uropathogen, a follow up visit at 7-21 days was conducted. Results: The analysis included 168 participants with a median age of 33.6 years (IQR 25.1-51.4) and of whom 131/168 (78.0%) were female. Effective treatment was taken by 54/168 (32.1%) participants. The urine culture was negative at follow up in 41/54 (75.9%) of participants who took appropriate treatment and in 33/114 (28.9%, p<0.001) of those who did not. Symptoms had improved or resolved in 52/54 (96.3%) of those on appropriate treatment and in 71/114 (62.3%, p<0.001) of those without. Conclusion: The findings of this study show that effective treatment leads to symptom resolution and bacterial clearance in people presenting with UTIs to primary care. Although UTIs are not life-threatening and can resolve without treatment, they do impact on quality of life, highlighting the need for optimised treatment recommendations.

Risk factors for sustained virological non-suppression among children and adolescents living with HIV in Zimbabwe and Malawi: a secondary data analysis

BackgroundWe investigated risk factors for sustained virological non-suppression (viral load ≥ 1000 copies/ml on two tests 48 weeks apart) among children and adolescents accessing HIV care in public sector clinics in Harare, Zimbabwe and Blantyre, Malawi.MethodsParticipants were enrolled between 2016 and 2019, were aged 6–19 years, living with HIV, had chronic lung disease (FEV z-score < -1) and had taken antiretroviral therapy (ART) for at least six months. We used multivariate logistic regression to identify risk factors for virological non-suppression after 48 weeks, among participants who were non-suppressed at enrolment.ResultsAt enrolment 258 participants (64.6%) were on first-line ART and 152/347 (43.8%) had virological non-suppression. After 48 weeks 114/313 (36.4%) were non-suppressed. Participants non-suppressed at baseline had almost ten times higher odds of non-suppression at follow-up (OR = 9.9, 95%CI 5.3–18.4, p < 0.001). Of those who were non-suppressed at enrolment, 87/136 (64.0%) were still non-suppressed at 48 weeks. Among this group non-suppression at 48 weeks was associated with not switching ART regimen (adjusted OR = 5.55; 95%CI 1.41–21.83); p = 0.014) and with older age. Twelve participants switched regimen in Zimbabwe and none in Malawi.ConclusionsViral non-suppression was high among this group and many with high viral load were not switched to a new regimen, resulting in continued non-suppression after 48 weeks. Further research could determine whether improved adherence counselling and training clinicians on regimen switches can improve viral suppression rates in this population.Trial registrationSecondary cohort analysis of data from BREATHE trial (Clinicaltrials.gov NCT02426112).

Knowledge, attitudes and practices relating to antibiotic use and resistance among prescribers from public primary healthcare facilities in Harare, Zimbabwe.

Background Overuse of antibiotics is one of the main drivers for antimicrobial resistance (AMR). Globally, most antibiotics are prescribed in the outpatient setting. This survey aimed to explore attitudes and practices with regards to microbiology tests, AMR and antibiotic prescribing among healthcare providers at public primary health clinics in Harare, Zimbabwe. Methods This cross-sectional survey was conducted in nine primary health clinics located in low-income suburbs of Harare between October and December 2020. In Zimbabwe, primary health clinics provide nurse-led outpatient care for acute and chronic illnesses. Healthcare providers who independently prescribe antibiotics and order diagnostic tests were invited to participate. The survey used self-administered questionnaires. A five-point Likert scale was used to determine attitudes and beliefs. Results A total of 91 healthcare providers agreed to participate in the survey. The majority of participants (62/91, 68%) had more than 10 years of work experience. Most participants reported that they consider AMR as a global (75/91, 82%) and/or national (81/91, 89%) problem, while 52/91 (57%) considered AMR to be a problem in their healthcare facilities. A fifth of participants (20/91, 22%) were unsure if AMR was a problem in their clinics. Participants felt that availability of national guidelines (89/89, 100%), training sessions on antibiotic prescribing (89/89, 100%) and regular audit and feedback on prescribing (82/88, 93%) were helpful interventions to improve prescribing. Conclusions These findings support the need for increased availability of data on AMR and antibiotic use in primary care. Educational interventions, regular audit and feedback, and access to practice guidelines may be useful to limit overuse of antibiotics.

TRIM22 genotype is not associated with markers of disease progression in children with HIV-1 infection.

Untreated perinatal HIV-1 infection is often associated with rapid disease progression in children with HIV (CWH), characterized by high viral loads and early mortality. TRIM22 is a host restriction factor, which directly inhibits HIV-1 transcription, and its genotype variation is associated with disease progression in adults. We tested the hypothesis that TRIM22 genotype is associated with disease progression in CWH. ART-naive CWH, aged 6-16 years, were recruited from primary care clinics in Harare, Zimbabwe. We performed a candidate gene association study of TRIM22 genotype and haplotypes with markers of disease progression and indicators of advanced disease. TRIM22 exons three and four were sequenced by Sanger sequencing and single nucleotide polymorphisms were associated with markers of disease progression (CD4+ T-cell count and HIV viral load) and clinical indicators of advanced HIV disease (presence of stunting and chronic diarrhoea). Associations were tested using multivariate linear and logistic regression models. A total of 241 children, median age 11.4 years, 50% female, were included. Stunting was present in 16% of participants. Five SNPs were analyzed including rs7935564, rs2291842, rs78484876, rs1063303 and rs61735273. The median CD4+ count was 342 (IQR: 195-533) cells/μl and median HIV-1 viral load 34 199 (IQR: 8211-90 662) IU/ml. TRIM22 genotype and haplotypes were not associated with CD4+ T-cell count, HIV-1 viral load, stunting or chronic diarrhoea. TRIM22 genotype was not associated with markers of HIV disease progression markers or advanced disease in CWH.

Sexually transmitted infections and prior antibiotic use as important causes for negative urine cultures among adults presenting with urinary tract infection symptoms to primary care clinics in Zimbabwe: a cross-sectional study

Evaluation of the InTray and Compact Dry culture systems for the diagnosis of urinary tract infections in patients presenting to primary health clinics in Harare, Zimbabwe

Antimicrobial resistance surveillance data is lacking from many resource-limited settings mainly due to limited laboratory testing. Novel culture systems may address some of the limitations of conventional culture media and expand the availability of microbiology services. The aims of this study were to evaluate the performance of InTray COLOREX Screen/ESBL and Compact Dry for the detection of uropathogens and of extended-spectrum beta-lactamase (ESBL)-producing organisms from urine samples. Urines samples were collected from patients presenting with symptoms of urinary tract infection to primary care clinics in Harare. Performance of the InTray COLOREX Screen, ESBL and Compact Dry chromogenic media were compared to the reference of culture using Brilliance UTI agar and conventional antimicrobial susceptibility testing. A total of 414 samples were included in the analysis. Of the included samples, 98 were positive on Brilliance UTI agar and 83 grew Enterobacterales. The sensitivities and specificities for Enterobacterales were 89.2% (95% CI 80.4–94.9) and 98.2% (95% CI 96.1–99.3) for InTray Screen and 95.2% (95% CI 88.1–98.7) and 99.7% (95% CI 98.3–100) for Compact Dry. Extended-spectrum beta-lactamases were present in 22 isolates from the Brilliance UTI agar. The sensitivity of the InTray COLOREX ESBL culture plates for the detection of ESBL-producing organisms was 95.5% (95% CI 77.2–99.9) and specificity was 99.5% (95% CI 98.2–99.9%). Our findings show good performance of the novel culture systems for the detection of uropathogens and ESBL-producing organisms. Both systems have several advantages over conventional media and have the potential to expand and decentralize laboratory testing.

Prevalence of ESBL-producing Escherichia coli in adults with and without HIV presenting with urinary tract infections to primary care clinics in Zimbabwe.

BackgroundPeople living with HIV may be at increased risk for infections with resistant organisms. Infections with ESBL-producing organisms are of particular concern because they limit treatment options for severe Gram-negative infections in low-resource settings.ObjectivesTo investigate the association between HIV status and urinary tract infections (UTIs) with ESBL-producing Escherichia coli.Patients and methodsCross-sectional study enrolling adults presenting with UTI symptoms to primary care clinics in Harare, Zimbabwe. Demographic and clinical data were collected during interviews and a urine sample was collected for culture from each participant. Antimicrobial susceptibility testing was performed according to EUCAST recommendations.ResultsOf the 1164 who were enrolled into the study, 783 (64%) were female and 387 (33%) were HIV infected. The median age was 35.8 years. Urine cultures were positive in 338 (29.0%) participants, and the majority of bacterial isolates were E. coli (n = 254, 75.2%). The presence of ESBL was confirmed in 49/254 (19.3%) E. coli. Participants with HIV had a 2.13 (95% CI 1.05–4.32) higher odds of infection with ESBL-producing E. coli than individuals without HIV. Also, the prevalence of resistance to most antimicrobials was higher among participants with HIV.ConclusionsThis study found an association between HIV and ESBL-producing E. coli in patients presenting with symptoms suggestive of UTI to primary care in Harare. HIV status should be considered when prescribing empirical antimicrobial treatment.

The causes of infertility in women presenting to gynaecology clinics in Harare, Zimbabwe; a cross sectional study

BackgroundInfertility affects 48.5 million couples globally. It is defined clinically as failure to conceive after 12 months or more of regular unprotected sexual intercourse. The contribution of various aetiological factors to infertility differs per population. The causes of infertility have not been assessed in Zimbabwe. Our objectives were to determine the reproductive characteristics, causes and outcomes of women presenting for infertility care.MethodsA retrospective and prospective study of women who had not conceived within a year of having unprotected intercourse presenting in private and public facilities in Harare was done. A diagnosis was made based on the history, examination and results whenever these were deemed sufficient. Data was analysed using STATA SE/15. A total of 216 women were recruited.ResultsOf the 216 women recruited, two thirds (144) of them had primary infertility. The overall period of infertility ranged from 1 to 21 years with an average of 5.6 ± 4.7 years whilst 98 (45.4%) of the couples had experienced 2–4 years of infertility and 94 (43.5%) had experience 5 or more years of infertility. About 1 in 5 of the women had irregular menstrual cycles with 10 of them having experienced amenorrhoea of at least 1 year. Almost half of the participants (49%) were overweight or obese. The most common cause for infertility was ‘unexplained’ in 22% of the women followed by tubal blockage in 20%, male factor in 19% and anovulation in 16%. Of the 49 (22.7%) women who conceived 21(9.7%) had a live birth while 23 (10.7%) had an ongoing pregnancy at the end of follow up. Thirty-seven (17.1%) had Assisted Reproduction Techniques (ART) in the form of Invitro-fertilisation/Intracytoplasmic Sperm Injection (IVF/ICSI) or Intra-Uterine Insemination (IUI). Assisted Reproduction was significantly associated with conception.ConclusionMost women present when chances of natural spontaneous conception are considerably reduced. This study shows an almost equal contribution between tubal blockage, male factor and unexplained infertility. Almost half of the causes are female factors constituted by tubal blockage, anovulation and a mixture of the two. Improved access to ART will result in improved pregnancy rates. Programs should target comprehensive assessment of both partners and offer ART.

Investigations and treatment offered to women presenting for infertility care in Harare, Zimbabwe: a cross sectional study.

Introductionclinical infertility is failure to conceive within a year of regular sexual intercourse by a non contracepting couple. Infertility care is costly and result in investigations being incomplete and inconclusive. It is therefore important to streamline investigations offered to infertile couples such that only the most cost effective tests are done. This paper explores the adequacy of investigations and treatments offered to women presenting for infertility care.Methodsthe data used in this analysis was obtained from a cross sectional sample of 216 women who presented with infertility in public and private gynaecological clinics in Harare, Zimbabwe. Information on investigations and treatment offered to women presenting for care was extracted from hospital cards, case notes, laboratory and radiological reports. Data was analysed using STATA SE/15.Resultsof the 178 (82.4%) who had ultrasound scan evaluation (USS) 50 (28.1%) had fibroids and 22 (12.4%) had polycystic ovaries. Tubal patency tests were done in 118 participants using (hystero-salpingogram) HSG alone in 62.7%, laparoscope and dye alone in 21.2% and both in 16.1% of them. Of the 97 (44.9%) men who had semen analysis 61 (62.9%) had abnormal parameters.Conclusionthis study reveals that evaluation for tubal patency and USS to rule out reproductive organ pathology are not being offered to all women with a diagnosis of infertility. Likewise, male partner semen evaluation is not being done in all male partners. There is a high prevalence of abnormal semen parameters. Studies should be done to understand why some male partners are not forthcoming in providing semen for analysis. It is important for protocols to be produced by professional bodies which prescribe the minimum basic investigations in couples with infertility.

Effect of HIV Infection on Growth and Bone Density in Peripubertal Children in the Era of Antiretroviral Therapy: A Cross-Sectional Study in Zimbabwe

Background: Poor linear growth and pubertal delay, both common in children with HIV (CWH) in sub-Saharan Africa, may affect adolescent bone accrual and future fragility fracture risk. We investigated the association of HIV with size-adjusted bone density in peri-pubertal children in Zimbabwe. Methods: CWH aged 8-16 years taking ART for ≥2 years from public-sector HIV clinics in Harare, and HIV-uninfected children from schools in the same catchment area, were recruited into a cross-sectional study. Sociodemographic, clinical and anthropometric data were collected. Outcomes were dual-energy X-ray absorptiometry (DXA) measured total-body less-head bone mineral content-for-lean mass adjusted for height (TBLH-BMCLBM) and lumbar spine bone mineral apparent density (LS-BMAD). Linear regression models using multiple imputation for missing data, assessed relationships between risk factors and DXA measures by HIV status, and interaction by sex and pubertal (Tanner) stage. Findings: We recruited 303 CWH and 306 without HIV, mean (SD) age 12.5 (2.5) years and 50% female. Mean ART duration was 7.9 (2.6) years; for 34% ART included tenofovir disproxil fumarate (TDF). The prevalence of low TBLH-BMCLBM and LS-BMAD (Z-Score<-2) was higher in children with than without HIV (10.4% vs. 6.2%, p=0.066; 14.3% vs. 5.8%, p=0.001 respectively). HIV and male sex were associated with earlier Tanner stage. The negative effects of HIV on TBLH-BMCLBM and LS-BMAD were more pronounced with pubertal maturation, particularly in females. Among CWH, years of TDF exposure and orphanhood were strongly associated with lower TBLH-BMCLBM Z-Score in both unadjusted and adjusted analyses. Current TDF use was associated with 0.40 (95%CI 0.07, 0.73; p=0.018) and 0.31 (0.07, 0.69; p=0.110) lower TBLH-BMCLBM and LS-BMAD Z-Scores respectively. Interpretation: Despite ART, HIV is associated with substantial skeletal deficits by the end of puberty. The size of bone deficits associated with TDF and its widespread use in children in sub-Saharan Africa raise concern for future adult fracture risk. Funding Statement: Wellcome Trust.

Antimicrobial Resistance in Gram-negative bacteria from Urinary Specimens: a study of prevalence, risk factors and molecular mechanisms of resistance (ARGUS) in Zimbabwe – a study protocol

Antimicrobial resistance (AMR) is compromising our ability to successfully treat infections. There are few data on gram-negative AMR prevalence in sub-Saharan Africa especially from the outpatient setting. This study aims to investigate the prevalence of and underlying molecular mechanisms for AMR in gram-negative bacilli causing urinary tract infections (UTIs) in Zimbabwe. Risk factors for AMR and how AMR impacts on clinical outcomes will also be investigated. Adults presenting with UTI symptoms at primary health clinics in Harare will be included. A questionnaire will be administered, and urine samples will be collected for culture. Participants with positive urine cultures will be followed up at 7-14 days post-enrolment. All participants will also be followed by telephone at 28 days to determine clinical outcomes. Bacterial identification and antibiotic susceptibility testing will be performed on positive cultures. The results from this study will be used to inform policy and development of treatment recommendations. Whole genome sequencing results will provide a better understanding of the prevalent resistance genes in Zimbabwe, of the spread of successful clones, and potentially will contribute to developing strategies to tackle AMR.
