RESUMO

For adults and adolescents, the World Health Organization defines advanced HIV disease (AHD) as a CD4 (cluster of differentiation 4) count of <200 cells/mm3 or a clinical stage 3 or 4 event. We describe clinical outcomes in a cohort of AHD patients at two regional hospitals in Lesotho. From November 2018-June 2019, we prospectively enrolled eligible patients (≥15 years) not on antiretroviral therapy (ART) presenting with WHO-defined AHD into a differentiated model of care for AHD (including rapid ART initiation) and followed them for six months. All patients received Tuberculosis (TB) symptom screening with further diagnostic testing; serum cryptococcal antigen (CrAg) screening was done for CD4 <100 cells/mm3 or WHO clinical stage 3 or 4. Medical record data were abstracted using visit checklist forms. Categorical and continuous variables were summarized using frequencies, percentages, and means, respectively. Kaplan-Meier was used to estimate survival. Of 537 HIV-positive patients screened, 150 (27.9%) had AHD of which 109 were enrolled. Mean age was 38 years and 62 (56.9%) were men. At initial clinic visit, 8 (7.3%) were already on treatment and 33% (36/109) had presumptive TB per symptom screening. Among 39/109 (40.2%) patients screened for CrAg at initial visit, five (12.8%) were CrAg-positive. Among 109 enrolled, 77 (70.6%) initiated ART at their initial clinic visit, while 32 delayed ART initiation (median delay: 14 days). Of the 109 participants enrolled, 76 (69.7%) completed the 6-month follow-up, 17 (15.6%) were lost to follow-up, 5 (4.6%) transferred to other health facilities and 11 (10.1%) died. The 6-month survival was 87.4%; among 74 patients with a viral load result, 6-month viral suppression (<1,000 copies/ml) was 85.1%. Our study found that even after the implementation of Test and Treat of ART in 2016 in Lesotho, over 25% of patients screened had AHD. Patients with AHD had a high prevalence of TB and CrAg positivity, underscoring the need to assess for AHD and rapidly initiate ART within a package of AHD care for optimal patient outcomes.

RESUMO

Zimbabwe introduced raltegravir (RAL) granules at 14 facilities providing point-of-care HIV birth testing, aiming to initiate all newborns with HIV on a RAL-based regimen. From June 2020 to July 2021, we tested 3172 of the 6989 (45%) newborns exposed to HIV; we diagnosed 59(2%) with HIV infection, of whom 27 (46%) initiated RAL. The SARS-CoV-2 coronavirus disease pandemic exacerbated supply chain and trained provider shortages, contributing to low birth testing, RAL uptake and 6-month viral load testing.

RESUMO

BACKGROUND: In 2020, Zimbabwe adopted the WHO's recommendation to use raltegravir (RAL) granule-based regimens for treatment of neonates identified with HIV at the time of birth testing. This study explores the acceptability of RAL granules by caregivers and healthcare workers (HCWs). METHODS: Interviews were conducted with 15 caregivers and 12 HCWs from 8 health facilities in Zimbabwe participating in the introductory pilot of RAL granules treatment for newborns. Eligible caregivers included those who had administered RAL to their infant and attended either 8th or 28th day of life appointments. Caregivers of neonates recently initiated on RAL were selected through convenience sampling. Eligible HCWs who provided RAL preparation, administration instructions and support to caregivers of neonates on RAL for at least 3 months were recruited from the same facilities as the caregivers. Interview transcripts were coded and thematically analysed. RESULTS: Caregivers reported that their babies looked healthier after RAL initiation, with improved skin appearance and weight gain. Some caregivers wanted their child to remain on RAL beyond 28 days instead of switching regimens, as recommended by national guidelines. HCWs observed that RAL granules improved health outcomes compared with other regimens. HCWs reported challenges with caregivers understanding dosing instructions, measuring with a syringe, swirling and not shaking the medicine, discarding unused medication and following the changes in the dosing schedule and amount when RAL was initiated a few days after birth. HCWs stated that adequate counselling and repeat demonstrations were crucial to ensure that caregivers clearly understood RAL dosing and administration instructions. HCWs requested more standardised training targeting nurses with guidance on handling missed doses and clarification on mixing RAL granules with water and not breastmilk. CONCLUSION: While feedback from caregivers and HCWs on RAL implementation was positive, barriers were also noted. Adequate training and sufficient instruction and support for caregivers would help to ensure that RAL granules are prepared, dosed and administered correctly.

RESUMO

BACKGROUND: Knowledge of HIV status remains a challenge despite implementation of various testing strategies including provider-initiated HIV testing (PITC). Harare City intensified provider-initiated HIV testing by targeting testing all eligible clients visiting facilities to achieve the UNAIDS first 95. This study aimed at evaluating the intervention to improve its effectiveness and inform programming decisions for universal access to HIV testing. METHODS: A descriptive cross-sectional study was conducted in Harare from April to June 2019. Evaluation of the intervention was conducted using the logic model approach to assess the inputs, processes and outputs. Health workers were interviewed using an interviewer administered questionnaire. Exit interviews were conducted for eligible clients > 18 years who refused to be tested. A checklist was used to assess the inputs used and a desk review of HIV screening and testing records was done. RESULTS: A total of (n-45) health care workers and (n = 70) clients were interviewed with a response rate of (92%) and (84%) respectively. The median age for clients was 31(Q1 = 24: Q3 = 38) and median years in service for health workers was 2 (Q1 = 1;Q3 = 26). Of the 133,899 clients who were eligible for testing after screening, 98,587 (74%) accepted the test leaving a gap of 35,312 (26%). However, 21/45 (47%) of health workers indicated high workload in the morning as the major reason for the leakage. In addition, 25/70 (36%) of the clients indicated long waiting time as the reason for opting out of HIV testing. CONCLUSION AND RECOMMENDATION: HIV testing coverage for eligible clients was not optimal, 26% opted out. We recommend strengthening of health facility systems such as review of patient flow, re-allocation of staff during busy HIV testing time and scaling up the use of HIV self-test kits for clients concerned with waiting time to improve HIV testing coverage.

RESUMO

BACKGROUND: Dual human immunodeficiency virus (HIV)/syphilis rapid, point-of-care testing may enhance syphilis screening among high-risk populations, increase case finding, reduce time to treatment, and prevent complications. We assessed the laboratory-based performance of a rapid dual HIV/syphilis test using serum collected from patients enrolled in the Zimbabwe Sexually Transmitted Infections (STI) Etiology study. METHODS: Blood specimens were collected from patients presenting with STI syndromes in 6, predominantly urban STI clinics in different regions of Zimbabwe. All specimens were tested at a central research laboratory using the Standard Diagnostics Bioline HIV/Syphilis Duo test. The treponemal syphilis component of the dual rapid test was compared with the Treponema pallidum hemagglutination assay (TPHA) as a gold standard comparator, both alone or in combination with a nontreponemal test, the rapid plasma reagin test. The HIV component of the dual test was compared with a combination of HIV rapid tests conducted at the research laboratory following the Zimbabwe national HIV testing algorithm. RESULTS: Of 600 men and women enrolled in the study, 436 consented to serological syphilis and HIV testing and had specimens successfully tested by all assays. The treponemal component of the dual test had a sensitivity of 66.2% (95% confidence interval [CI], 55.2%-77.2%) and a specificity of 96.4% (95% CI, 94.5%-98.3%) when compared with TPHA; the sensitivity increased to 91.7% (95% CI, 82.6%-99.9%) when both TPHA and rapid plasma reagin were positive. The HIV component of the dual test had a sensitivity of 99.4% (95% CI, 98.4%-99.9%) and a specificity of 100% (95% CI, 99.9%-100%) when compared with the HIV testing algorithm. CONCLUSIONS: Laboratory performance of the SD Bioline HIV/Syphilis Duo test was high for the HIV component of the test. Sensitivity of the treponemal component was lower than reported from most laboratory-based evaluations in the literature. However, sensitivity of the test increased substantially among patients more likely to have active syphilis for which results of both standard treponemal and nontreponemal tests were positive.

RESUMO

BACKGROUND: Syphilis prevalence in sub-Saharan Africa appears to be stable or declining but is still the highest globally. Ongoing sentinel surveillance in high-risk populations is necessary to inform management and detect changes in syphilis trends. We assessed serological syphilis markers among persons with sexually transmitted infections in Zimbabwe. METHODS: We studied a predominantly urban, regionally diverse group of women and men presenting with genital ulcer disease (GUD), women with vaginal discharge and men with urethral discharge at clinics in Zimbabwe. Syphilis tests included rapid plasma reagin and the Treponema pallidum hemagglutination assay. RESULTS: Among 436 evaluable study participants, 36 (8.3%) tested positive for both rapid plasma reagin and Treponema pallidum hemagglutination assay: women with GUD: 19.2%, men with GUD: 12.6%, women with vaginal discharge: 5.7% and men with urethral discharge: 1.5% (P < 0.0001). CONCLUSIONS: Syphilis rates in Zimbabwe are high in sentinel populations, especially men and women with GUD.

RESUMO

BACKGROUND: Maternal Death Surveillance and Response (MDSR) system was established to provide information that effectively guides actions to eliminate preventable maternal mortality. In 2016, Hwange district sent six maternal death notification forms (MDNF) to the province without maternal death audit reports. Timeliness of MDNF reaching the province is a challenge. Two MDNF for deaths that occurred in February and May 2016 only reached the provincial office in September 2016 meaning the MDNF were seven and four months late respectively. We evaluated the MDSR system in Hwange district. METHODS: A descriptive cross-sectional study was conducted. Health workers in the sampled facilities were interviewed using questionnaires. Resource availability was assessed through checklists. Epi Info 7 was used to calculate frequencies, means and proportions. RESULTS: We recruited 36 respondents from 11 facilities, 72.2% were females. Inadequate health worker knowledge, lack of induction on MDSR, unavailability of guidelines and notification forms and lack of knowledge on the flow of information in the system were reasons for late notification of maternal deaths. Workers trained in MDSR were 83.8%. Only 36.1% of respondents had completed an MDNF before. Respondents who used MDSR data at their level were 91.7%, and they reported that MDSR system was useful. Responsibility to complete the MDNF was placed on health workers. Maternal death case definitions were available in 2/11 facilities, 4/11 facilities had guidelines for maternal death audits. It costs $60.78 to notify a maternal death. CONCLUSION: Reasons for late notification of maternal deaths were inadequate knowledge, lack of induction, unavailability of guidelines and notification forms at facilities. The MDSR system is useful, acceptable, flexible, unstable, reliable but not simple. Maternal case definitions and maternal death audit guidelines should be distributed to all facilities. Training of all health workers involved in MDSR is recommended.

RESUMO

BACKGROUND: Zimbabwe is on track towards achieving viral suppression among adults (87%). However, adolescents have only achieved 44% by 2016. In Harare city, 57% of adolescents had attained viral suppression after 12 months on ART compared to 88% among adults. We determined factors associated with virological failure among adolescents (age 10-19 years) on antiretroviral therapy (ART) in Harare city. METHODS: We conducted a one to one unmatched case control study among 102 randomly recruited case: control pairs at the two main infectious disease hospitals in Harare. A case was any adolescent who presented with VL > 1000c/ml after at least 12 months on ART. A control was any adolescent who presented with VL < 1000c/ml after at least 12 months on ART. Interviewer administered questionnaires were used to collect data. Epi Info 7 was used to generate frequencies, means, proportions, ORs and p-values at 95% CI. RESULTS: We interviewed 102 case-control pairs. Poor adherence to ART [aOR = 8.15, 95% CI (2.80-11.70)], taking alcohol [aOR = 8.46, 95% CI (3.22-22.22)] and non- disclosure of HIV status [aOR = 4.56, 95% CI (2.20-9.46)] were independent risk factors for virological failure. Always using a condom [aOR = 0.04, 95% CI (0.01-0.35)], being on second line treatment [aOR = 0.04, 95% CI (0.23-0.81)] and belonging to a support group [aOR = 0.41, 95% CI (0.21-0.80)] were protective. CONCLUSION: Poor adherence, alcohol consumption and non-disclosure increased the odds of virological failure. Based on these findings support should focus on behavior change and strengthening of peer to peer projects to help address issues related to disclosure and adherence. Further operational research should aim to define other components of effective adherence support for adolescents with virological failure.

RESUMO

INTRODUCTION: Sexually transmitted infections (STIs) are managed syndromically in most developing countries. In Zimbabwe, men presenting with urethral discharge are treated with a single intramuscular dose of kanamycin or ceftriaxone in combination with a week's course of oral doxycycline. This study was designed to assess the current etiology of urethral discharge and other STIs to inform current syndromic management regimens. METHODS: We conducted a study among 200 men with urethral discharge presenting at 6 regionally diverse STI clinics in Zimbabwe. Urethral specimens were tested by multiplex polymerase chain reaction testing for Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, and Trichomonas vaginalis. In addition, serologic testing for syphilis and HIV was performed. RESULTS: Among the 200 studied men, one or more pathogens were identified in 163 (81.5%) men, including N. gonorrhoeae in 147 (73.5%), C. trachomatis in 45 (22.5%), T. vaginalis in 8 (4.0%), and M. genitalium in 7 (3.5%). Among all men, 121 (60%) had a single infection, 40 (20%) had dual infections, and 2 (1%) had 3 infections. Among the 45 men with C. trachomatis, 36 (80%) were coinfected with N. gonorrhoeae. Overall, 156 (78%) men had either N. gonorrhoeae or C. trachomatis identified. Of 151 men who consented to HIV testing, 43 (28.5%) tested positive. There were no differences in HIV status by study site or by urethral pathogen detected. CONCLUSIONS: Among men presenting at Zimbabwe STI clinics with urethral discharge, N. gonorrhoeae and C. trachomatis are the most commonly associated pathogens. Current syndromic management guidelines seem to be adequate for the treatment for symptomatic men, but future guidelines must be informed by ongoing monitoring of gonococcal resistance.

RESUMO

BACKGROUND: In many countries, sexually transmitted infections (STIs) are treated syndromically. Thus, patients diagnosed as having genital ulcer disease (GUD) in Zimbabwe receive a combination of antimicrobials to treat syphilis, chancroid, lymphogranuloma venereum (LGV), and genital herpes. Periodic studies are necessary to assess the current etiology of GUD and assure the appropriateness of current treatment guidelines. MATERIALS AND METHODS: We selected 6 geographically diverse clinics in Zimbabwe serving high numbers of STI cases to enroll men and women with STI syndromes, including GUD. Sexually transmitted infection history and risk behavioral data were collected by questionnaire and uploaded to a Web-based database. Ulcer specimens were obtained for testing using a validated multiplex polymerase chain reaction (M-PCR) assay for Treponema pallidum (TP; primary syphilis), Haemophilus ducreyi (chancroid), LGV-associated strains of Chlamydia trachomatis, and herpes simplex virus (HSV) types 1 and 2. Blood samples were collected for testing with HIV, treponemal, and nontreponemal serologic assays. RESULTS: Among 200 GUD patients, 77 (38.5%) were positive for HSV, 32 (16%) were positive for TP, and 2 (1%) were positive for LGV-associated strains of C trachomatis. No H ducreyi infections were detected. No organism was found in 98 (49.5%) of participants. The overall HIV positivity rate was 52.2% for all GUD patients, with higher rates among women compared with men (59.8% vs 45.2%, P < 0.05) and among patients with HSV (68.6% vs 41.8%, P < 0.0001). Among patients with GUD, 54 (27.3%) had gonorrhea and/or chlamydia infection. However, in this latter group, 66.7% of women and 70.0% of men did not have abnormal vaginal or urethral discharge on examination. CONCLUSIONS: Herpes simplex virus is the most common cause of GUD in our survey, followed by T. pallidum. No cases of chancroid were detected. The association of HIV infections with HSV suggests high risk for cotransmission; however, some HSV ulcerations may be due to HSV reactivation among immunocompromised patients. The overall prevalence of gonorrhea and chlamydia was high among patients with GUD and most of them did not meet the criteria for concomitant syndromic management covering these infections.

RESUMO

INTRODUCTION: In Zimbabwe the integrated disease surveillance and response guidelines include maternal mortality as a notifiable event reported through the Maternal Mortality Surveillance System (MMSS). A preliminary review of the MMSS data for Mutare district for the period January to June 2014 revealed that there were some discrepancies in cases notified and those captured on the T5 monthly return form. There were also delays in reporting of some maternal deaths. Poor reporting indicated shortcomings in the MMSS in Mutare district and we therefore sought to assess the performance of the maternal mortality surveillance system in Mutare district. METHODS: A descriptive cross sectional study was conducted using Centers for Disease Control and Prevention updated guidelines for evaluating public health surveillance systems. A total of 64 health workers were enrolled into the study from 19 selected health facilities in Mutare district and 32 maternal death notification forms submitted in 2014 to the provincial office were reviewed to assess the quality of information on the forms. Interviewer administered questionnaires were used to collect information from enrolled health workers, the system's attributes namely usefulness, acceptability, simplicity, stability, data quality, timeliness and completeness were assessed and a checklist was used to assess availability of resources for the implementation of the maternal mortality surveillance. We also determined the cost of reporting each maternal death in Mutare district. RESULTS: Half of the study participants gave the correct definition of a maternal death. All health workers participated and were willing to continue participating in the maternal mortality surveillance. Majority of health workers, 79.7% used data generated from the surveillance system and 59.5% found it easy to implement the system. A total of 32 death notification forms were reviewed and of these, 31 forms were forwarded to the national office and all did not reach the national office on time. Average completeness of notification forms was 76.0% and 53.1% of the forms had all the necessary accompanying documents. Reporting each maternal death was estimated to cost $28.65 in Mutare district. CONCLUSION: The strongest components of the maternal mortality surveillance system in Mutare district were usefulness and acceptability. Timeliness and completeness were the weaker components of the system. The system was found to be simple; however, resources were not adequately available in all health facilities.

RESUMO

INTRODUCTION: Medicines have the potential to cause adverse drug reactions and because of this Zimbabwe monitor reactions to medicines through the Adverse Drug Reaction Surveillance System. The Medicines Control Authority of Zimbabwe monitors reactions to medicines through the Adverse Drugs Reactions Surveillance System. The system relies on health professionals to report adverse drug reactions to maximize patient safety. We report results of an evaluation of the Adverse Drugs Reactions Surveillance System in Kadoma District. METHODS: A descriptive cross-sectional study was conducted using the updated CDC guidelines in six health facilities in Kadoma City. Data were collected using a pretested interviewer administered questionnaire, checklists and records review. Data was analyzed using Epi InfoTM to calculate frequencies and means. Qualitative data were analyzed manually. Written informed consent was obtained from all study participants. RESULTS: The surveillance system did not meet up to its objectives as it failed to detect the adverse drug reactions and there was no monitoring of increases in known events. Fewer than half (43%) of the participants were aware of at least 2 objectives of the surveillance system but 83% of health workers willing to participate. However the system was not acceptable, 79% did not perceive the system to be necessary with the majority saying ''why should we fill in the forms when the reactions were already known or minor''. Though the system was supposed to identify potential patient risk factors for particular types of events health workers were reluctant to participate as evidenced by only one form filled out of 20 reactions experienced in the district. The system was simple as the notification form has 16 fields which require easily obtainable information from the patient records. CONCLUSION: The surveillance system was not useful and was not acceptable to health workers but was simple and stable. Health workers lacked knowledge. Sharing of results with the Medicines Control Authority of Zimbabwe through the Matrons facilitated training of health workers in Kadoma City. Health workers were encouraged to notify any drug reaction and to completely fill in the notification forms. Patients were also encouraged to report any drug reaction to health care workers.

RESUMO

INTRODUCTION: Severe malaria is a rare life threatening illness. Only a small proportion of patients with clinical malaria progress to this medical emergency. On reviewing 61 malaria death investigation forms submitted to the provincial office in 2014, 22(36%) were children below ten years who succumbed to severe malaria. Mutasa and Nyanga Districts reported 73% of these deaths. This study was conducted to determine factors associated with severe malaria so as to come up with evidence based interventions to prevent severe malaria and associated mortality. METHODS: A 1:2 unmatched case control study was conducted. A case was defined as a child 10 years and below, who was admitted at Hauna (Mutasa) or Nyanga District Hospitals between September 2014 and May 2015 with a primary diagnosis of severe malaria. Controls were children of similar age with uncomplicated malaria. Permission to conduct the study was sought and granted by the Medical Research Council of Zimbabwe (Approval number B/874), Joint Research Ethics Committee, Health Studies Office and the Manicaland Directorate Institutional Review Board. Written informed consent was sought from all caregivers of enrolled children. Interviewer administered questionnaires were used to ascertain exposures. RESULTS: A total of 52 cases and 104 controls were enrolled into the study. The median age of cases was 4 years (Q1=3, Q3=9) and 6 years for controls (Q1=3, Q3=8). The Case Fatality Rate among cases was 28.8%. The independent risk factors for severe malaria were; distance >10km to the nearest health facility [Adjusted Odds Ratio (aOR)=14.35, 95% CI=1.30, 158.81], duration of symptoms before seeking medical care >2 days [aOR=9.03, 95% CI=2.21, 36.93], having comorbidities [aOR=5.38, 95% CI=1.90, 15.19], staying in a house under construction [aOR=4.51, 95%CI=1.80, 11.32] and duration of illness before receiving antimalarial medicines >24 hours [aOR=3.82, 95% CI=1.44, 10.12]. Owning at least one ITN in the household [aOR=0.32, 95% CI=0.11, 0.95] and having a mother as a caregiver [aOR=0.23, 95% CI=0.09, 0.76] were independently protective of severe malaria. Being undernourished [Odds Ratio (OR)=10.13, 95% CI=1.04, 98.49] and being female [OR=0.27, 95% CI=0.08, 0.96] were associated with mortality owing to severe malaria. CONCLUSION: Factors associated with severe malaria and mortality owing to severe malaria identified in this study are consistent with other studies. Caregiver healthcare seeking behaviours, patient related factors and health system related factors are important determinants of severe malaria among children. There is need for regular health education campaigns emphasizing on malaria prevention, signs and symptoms and benefits of seeking medical care immediately for sick children.

RESUMO

INTRODUCTION: Zimbabwe targets reducing malaria incidence from 22/1000 in 2012 to 10/1000 by 2017, and malaria deaths to near zero by 2017. As the country moves forward with the malaria elimination efforts, it is crucial to monitor trends in malaria morbidity and mortality in the affected areas. In 2013, Manicaland Province contributed 51% of all malaria cases and 35% of all malaria deaths in Zimbabwe. This analysis describes the trends in malaria incidence, case fatality and malaria outpatient workload compared to the general outpatient workload. METHODS: We analyzed routinely captured malaria data in Manicaland Province for the period 2005 to 2014. Epi Info version 7 was used to calculate chi-square trends for significance and Microsoft Excel was used to generate graphs. Permission to analyze the data was sought and granted by the Provincial Medical Directorate Institutional Review Board of Manicaland and the Health Studies office. RESULTS: Malaria morbidity data for the period 2005-2014 was reviewed and a total of 947,462 cases were confirmed during this period. However, malaria mortality data was only available for the period 2011-2014 and cumulatively 696 deaths were reported. Malaria incidence increased from 4.4/1,000 persons in 2005 to 116.3/1,000 persons in 2014 (p<0.001). The incidence was higher among females compared to males (p-trend<0.001) and among the above five years age group compared to the under-fives (p-trend<0.001). The proportion of all Outpatient Department attendances that were malaria cases increased 30 fold from 0.3% in 2005 to 9.1% in 2014 (p-trend<0.001). The Case Fatality Rate also increased 2-fold from 0.05 in 2011 to 0.1 in 2014 (p-trend<0.001). CONCLUSION: Despite current malaria control strategies, the morbidity and mortality of malaria increased over the period under review. There is need for further strengthening of malaria control interventions to reduce the burden of the disease.

RESUMO

INTRODUCTION: Malaria is a preventable and curable disease. Mazowe district had been experiencing a lower malaria transmission rate in comparison to other districts in the Mashonaland Central province but it experienced a huge outbreak in the 2013-2014 rainy seasons with a case fatality rate (CFR) of 0.21%. This CFR was the highest in the province and it was twice as much as the national CFR (0.12%) for the same period. We evaluated severe malaria case management in Mazowe district to determine if practice is as per standard treatment guidelines. METHODS: A descriptive cross sectional study was conducted in Mazowe district using the Logical Framework approach. District Health Executives (DHE) members, nurses and severe malaria case notes were purposively and conveniently selected into the study. Key informant Interviews and review of case notes were carried out. All data were analysed using Epi Info 3.5.1.to calculate means and frequencies. Permission to conduct the study was obtained from the Mashonaland Central Provincial Medical Directorate (PMD) Institutional Ethical Review Board (IRB). RESULTS: The median age in years of the cases was 16 (Q1=7.3; Q3=30.8) and up to 58.1% of the cases were female. Inputs including staff, medicines and medical and laboratory equipment for severe case management were inadequate in the district. Only 60% of severe cases were diagnosed using blood slides and up to 95.6% of cases presented with one or more of the clinical signs of severe malaria. All severe cases were treated using correct anti-malarial and analgesic doses. Patient monitoring was not done as per prerequisite intervals and up to 5% of cases died. The health workers had above average knowledge on severe malaria. CONCLUSION: Severe malaria case management inputs were inadequate in the district. For many cases, the district did not follow complicated malaria treatment guidelines for diagnosis, treatment and monitoring. Untrained staff needs training in Severe Malaria Case Management and monitoring of commodity stocks needs to be strengthened.

RESUMO

BACKGROUND: Clients on anti-retroviral therapy (ART) are living longer and have risk of hypertension. Side effects of medicines and aging increase this risk. Hypertension prevalence among clients on ART in Kadoma City was estimated to be 30% in 2015. Of these, 61% had uncontrolled hypertension. This was high compared to 46% of hypertensives in the general population who had uncontrolled hypertension. We determined factors associated with uncontrolled hypertension among clients on ART. METHODS: A 1.1 unmatched case control study was conducted. Interviews, anthropometric measurements and record reviews were to collect data on demography and medical history. Epi Info 7 was used for univariate, bivariate analysis and logistic regression. RESULTS: One hundred and fifty-two cases and 152 controls were recruited into the study. Adding salt to dishes regularly aOR = 5.69 (3.19-10.16), body mass index (BMI) above 25 kg/m2 aOR = 2.81 (1.60-4.91) and history of elevated blood pressure in previous year aOR = 2.34 (1.33-4.13) were independent risk factors. Independent protective factors were duration more than 2 years since HIV diagnosis aOR = 0.58 (0.35-0.95), duration less than 5 years since hypertension diagnosis aOR = 0.50 (0.30-0.83) and walking or cycling as a means of transport aOR = 0.27 (0.16-0.48). CONCLUSION: Adding salt to dishes regularly, BMI above 25 kg/m2, history of elevated blood pressure in the previous year, duration more than 2 years since HIV diagnosis, duration less than 5 years since hypertension diagnosis and walking or cycling as a means of transport were independently associated with uncontrolled hypertension. Health education on lifestyle changes like walking and cycling as transport and dietary modification such as salt intake reduction were recommended.

RESUMO

BACKGROUND: Zimbabwe set up 12 sentinel sites to monitor HIV drug resistance (HIVDR) following the international standards for prevention of HIVDR from 2008 to 2010. METHODS: Participants were consecutively enrolled. Blood was collected and used for CD4 count, viral load (VL) and pre-treatment DR (PDR) tests besides routine baseline tests. We analyzed the characteristics of participants enrolled into the survey and estimated the point prevalence of PDR and its associated factors among ART initiators in a cross-sectional analysis using the baseline data collected from a prospective cohort in 12 purposefully selected sentinel sites. RESULTS: A total of 1728 participants (96 % response rate) were enrolled and 1610 had complete data. Of the 1610 there were more females (68.7 %) than males (31.3 %). The median CD4 count was 168 cells/mm(3) with males having lower values (P = 0.003). Ninety-six percent of participants had a VL ≥ 1000 copies/ml and the median VL was 128,000. Previous exposure to antiretroviral drugs (ARVs) was mainly through PMTCT (5 % of the participants). Overall, PDR mutations were detected in 6.3 % (95 % CI 5.2-7.7) of the 1480 successfully genotyped participants. However, the prevalence of PDR mutations was double for those with previous exposure (12.1 %) to ARVs compared with those without previous exposure (5.7 %, P = 0.002). CONCLUSIONS: The results show a moderate level of PDR prevalence among ART initiators. To maintain the efficacy of the current first-line regimens, there is need to strengthen all HIVDR prevention efforts and to conduct further studies to investigate optimal strategies that can prolong the efficacy of first-line ARV regimens in the country.

RESUMO

BACKGROUND: Despite widespread awareness and publicity concerning Human Immunodeficiency Virus (HIV) care and advances in treatment, many patients still present late in their HIV disease. Preliminary review of the Antiretroviral Therapy (ART) registers at Wilkins and Beatrice Road Hospitals, both located in Harare, indicated that 67 and 71 % of patients enrolled into HIV/AIDS care presented late with baseline CD4 of <200 cells/uL and/or WHO stage 3 and 4 respectively. We therefore sought to explore factors associated with late presentation in Harare City. METHODS: We conducted a 1:1 unmatched case control study where a case was an HIV positive individual (>18 years) with a baseline CD4 of <200/uL or who had WHO clinical stage 3 or 4 at first presentation to OI/ART centres in 2014 and; a control was HIV positive individual (>18 years) who had a baseline CD4 of >200/uL or WHO clinical stage 1 or 2 at first presentation in 2014. Written informed consent was obtained from all study participants. RESULTS: A total of 268 participants were recruited (134 cases and 134 controls). Independent risk factors for late presentation for HIV/AIDS care were illness being reason for test (Adjusted Odds Ratio [aOR] =7.68, 95 % CI = 4.08, 14.75); Being male (aOR = 2.84, 95 % CI = 1.50, 5.40) and; experienced HIV stigma (aOR = 2.99, 95 % CI = 1.54, 5.79). Independent protective factors were receiving information on HIV (aOR = 0.37, 95 % CI = 0.18, 0.78) and earning more than US$250 per month (aOR = 0.32, 95 % CI = 0.76, 0.67). Median duration between first reported HIV positive test result and enrolment into pre-ART care was 2 days (Q1 = 1 day; Q3 = 30 days) among cases and 30 days (Q1 = 3 days; Q3 = 75 days) among controls. CONCLUSION: Late presentation for HIV/AIDS care in Harare City was a result of factors that relate to the patient's sex, reason for getting a test, receiving HIV related information, experiencing stigma and monthly income. Based on this evidence we recommended targeted interventions to optimize early access to testing and enrolment into care.

RESUMO

BACKGROUND: Uptake of and adherence to the prevention of mother to child transmission of HIV (PMTCT) interventions are a challenge to most women if there is no male partner involvement. Organizations which include the National AIDS Council and the Zimbabwe AIDS Prevention Project- University of Zimbabwe have been working towards mobilizing men for couple HIV testing and counseling (HTC) in antenatal care (ANC). In 2013, Midlands province had 19 % males who were tested together with their partners in ANC, an increase by 9 % from 2011. However, this improvement was still far below the national target, hence this study was conducted to determine the associated factors. METHODS: A1:1 unmatched case control study was conducted. A case was a man who did not receive HIV testing and counseling together with his pregnant wife in ANC in Midlands province from January to June 2015. A control was a man who received HIV testing and counseling together with his pregnant wife in ANC in Midlands province from January to June 2015. Simple random sampling was used to select 112 cases and 112 controls. Epi Info statistical software was used to analyze data. Written informed consent was obtained from each study participant. RESULTS: Independent factors that predicted male involvement in PMTCT were: having been previously tested as a couple (aOR) 0.22, 95 % CI = 0.12, 0.41) and having time to visit the clinic (aOR) 0.41, 95 % CI = 0.21, 0.80). Being afraid of knowing one's HIV status (aOR 2.22, 95 % CI = 1.04, 4.76) was independently associated with low male involvement in PMTCT. CONCLUSION: Multiple factors were found to be associated with male involvement in PMTCT. Routine PMTCT educational campaigns in places where men gather, community based couple HTC and accommodating the working class during weekends are essential in fostering male involvement in PMTCT thereby reducing HIV transmission to the baby.
