RESUMO

BACKGROUND: Médecins Sans Frontières is supporting comprehensive HIV care and treatment for Kaposi Sarcoma (KS) in Guinea, where antiretroviral coverage is low and access to KS treatment is very limited. We aimed to evaluate treatment response and survival outcomes of epidemic KS in this setting. METHODS: Retrospective survival analysis of routinely collected clinical data of HIV-infected patients with clinically diagnosed KS, receiving ART and chemotherapy consisting of a combination of bleomycin and vincristine at the Donka National Hospital in Conakry between 2012 and 2015. RESULTS: A total of 225 patients were enrolled for KS treatment within the three-year period. Late presentation with stage T1 disease was common (82.7%). At the end of a median of 8 cycles of chemotherapy (IQR: 2-12), complete remission was observed in 65 (28.9%), partial remission in 53 (23.6%), stable disease in 15 (6.7%) and unknown response for all 92 (40.9%) patients who dropped out of care. The chances of achieving complete remission doubled after each additional cycle of chemotherapy (aOR = 2.09 95% CI: 1.44-3.01) but were reduced by about two-thirds for each additional month delay between treatment and onset of KS (aOR = 0.31, 95% CI: 0.11-0.86). Treatment response was seriously compromised in patients with woody skin oedema (aOR = 0.05, 95% CI: 0.01-0.38) and those with prior chemotherapy (aOR = 0.21, 95% CI: 0.05-0.80). The median survival time was 7.6 months (95% CI: 5.9-9.8). Attrition from care was reduced by 22% for every additional cycle of chemotherapy administered (aH0R = 0.78, 95% CI: 0.71-0.84) and was lower in those with complete remission compared with those with partial or no response (aHR = 0.05, 95% CI: 0.007-0.43). CONCLUSION: There has been an increased access to KS treatment. The overall response rate is 52.4%, which is considered a satisfactory result. Poor outcomes were common and were largely due to late presentation and defaulting on treatment. Efforts towards early HIV/KS diagnosis and adherence to a full round of chemotherapy are needed for optimising outcomes. Newer drugs may be required for patients previously exposed to chemotherapy.

RESUMO

INTRODUCTION: Médecins Sans Frontières supports human immunodeficiency virus (HIV)-infected youth, aged 12-25 years, at a clinic in Khayelitsha, South Africa. Patients are enrolled in youth clubs, and provided with a virtual chat room, using the cell-phone-based social networking platform, MXit, to support members between monthly/bimonthly club meetings. The acceptability and uptake of MXit was assessed. METHODS: MXit was facilitated by lay counsellors, was password protected, and participants could enter and leave at will. Club members were asked to complete self-administered questionnaires and participate in two focus-group discussions. RESULTS AND DISCUSSION: In total, 60 club members completed the questionnaire, and 12 participated in the focus groups. Fifty-eight percentage were aged 23-25 years, 63% were female and 83% had a cell phone. Sixty percentage had used MXit before, with 38% having used it in the past month. Sixty-five percentage were aware of the chat-room and 39% knew how to access it. Thirty-four percentage used the chat-room at least once, 20% had visited the chat-room in the past month, and 29% had used MXit to have private conversations with other club members. Fifty-seven percentage used the chat-room to get advice, and 84% of all respondents felt that offering a service outside the youth club meetings was important and would like to see one to continue. The cost of using social media platforms was an issue with some, as well as the need for anonymity. Preference for other platforms, logistical obstacles, or loss of interest contributed to non-use. CONCLUSIONS: Reported usage of the MXit chat-room was low, but participants indicated acceptance of the programme and their desire to interact with their peers through social media. Suggestions to improve the platform included accessible chat histories, using more popular platforms such as Facebook or WhatsApp, and to have topical discussions where pertinent information for youth is provided.

RESUMO

OBJECTIVE: To estimate the proportion of invalid results generated by a CD4+ T-lymphocyte analyser used by Médecins Sans Frontières (MSF) in field projects and identify factors associated with invalid results. METHODS: We collated 25,616 CD4+ T-lymphocyte test results from 39 sites in nine countries for the years 2011 to 2013. Information about the setting, user, training, sampling technique and device repair history were obtained by questionnaire. The analyser performs a series of checks to ensure that all steps of the analysis are completed successfully; if not, an invalid result is reported. We calculated the proportion of invalid results by device and by operator. Regression analyses were used to investigate factors associated with invalid results. FINDINGS: There were 3354 invalid test results (13.1%) across 39 sites, for 58 Alere PimaTM devices and 180 operators. The median proportion of errors per device and operator was 12.7% (interquartile range, IQR: 10.3-19.9) and 12.1% (IQR: 7.1-19.2), respectively. The proportion of invalid results varied widely by country, setting, user and device. Errors were not associated with settings, user experience or the number of users per device. Tests performed on capillary blood samples were significantly less likely to generate errors compared to venous whole blood. CONCLUSION: The Alere Pima CD4+ analyser generated a high proportion of invalid test results, across different countries, settings and users. Most error codes could be attributed to the operator, but the exact causes proved difficult to identify. Invalid results need to be factored into the implementation and operational costs of routine CD4+ T-lymphocyte testing.

RESUMO

HIV-1 viral load (VL) testing is not widely available in resource-limited settings. The use of finger prick dried blood spot (FP-DBS) samples could remove barriers related to sample collection and transport. Measurement of VL using DBS from EDTA venous blood (VB-DBS) in place of plasma has previously been validated using the NucliSENS Easy-Q HIV-1 v2.0 assay, but information on the accuracy of FP-DBS samples for measuring VL is limited. This prospective study, conducted at Thyolo District Hospital in southern Malawi, compared VL levels measured on FP-DBS samples and plasma using the NucliSENS Easy-Q HIV-1 v2.0 assay. Comparability was assessed by means of agreement and correlation (131 patients with VLs of ≥100 copies/ml), sensitivity, and specificity (612 patients on antiretroviral treatment [ART]). Samples of EDTA venous blood and FP-DBS from 1,009 HIV-infected individuals were collected and prepared in the laboratory. Bland-Altman analysis found good agreement between plasma and FP-DBS VL levels, with a mean difference of -0.35 log10, and 95% limits of agreement from -1.26 to 0.55 log10. FP-DBS had a sensitivity of 88.7% (95% confidence interval [CI], 81.1 to 94.4%) and a specificity of 97.8% (95% CI, 96.1 to 98.9%) using a 1,000-copies/ml cut point and a sensitivity of 83.0% (95% CI, 73.4 to 90.1%) and a specificity of 100% (95% CI, 99.3 to 100%) using a 5,000-copies/ml cut point. This study shows that FP-DBS is an acceptable alternative to plasma for measuring VL using the NucliSENS Easy-Q HIV-1 v2.0. We are conducting a second study to assess the proficiency of health workers at preparing FP-DBS in primary health care clinics.

RESUMO

BACKGROUND: CD4+ T-cell testing of blood specimens collected in standard EDTA Vacutainer tubes and transported at ambient temperature, must be completed within 48 hours with the BD FACSCount™ flow cytometer, restricting specimen collection in remote clinics with no on-site testing and limited specimen transport services. We conducted a study in Buhera District, Zimbabwe, to assess the stability and accuracy of CD4+ T-cell results of samples collected in Stabilization Tubes (ST) and stored at ambient temperature for varying time periods. METHODS: Paired EDTA and ST samples were collected from 51 HIV-positive patients aged 18 years and older. CD4+ T-cell testing was done on arrival in the laboratory (Day 0). ST samples were retested on Days 3, 5, and 7. Nineteen ST samples were stored for an additional week and retested on Day 14. RESULTS: There was a strong correlation between absolute CD4+ T-cell counts measured in the EDTA Day 0 reference sample and Day 7 ST sample (Spearman's rho: 0.9778; mean difference: -4.9 cells/µL and limits of agreement (LOA): 98.5 and 88.7 cells/µL); and the reference sample and Day 14 ST sample (Spearman's rho: 0.9632; mean difference 5.1 cells/µL and LOA: -99.6 and 109.8 cells/µL. Using a 350 cells/µL threshold, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were all 100% on Day 7, and 83.3%, 100%, 100% and 92.9% on Day 14. Using a 500 cells/µL threshold, the sensitivity, specificity, PPV and NVP were 100%, 88.5%, 88.5% and 100% on Day 7 and 88.9%, 80.0%, 80.0% and 88.9% on Day 14. CONCLUSIONS: CD4 ST can be used and stored up to 7 days as a reliable alternative to standard EDTA tubes in settings where CD4+ T-cell testing within 48 hours is not feasible. Despite the small sample size, results suggest that ST may be stored up to 14 days at room temperature for CD4 testing, without compromising accuracy. However, further studies with larger sample sizes are needed to confirm this preliminary finding.

RESUMO

Background: Evidence for acupuncture to treat pain is growing. Electrostimulation of acupuncture needles (electroacupuncture) is common for pain and is thought to augment the therapeutic effect. Objectives: To examine the association of pain outcomes after a single acupuncture session with electrostimulation included (EA) compared with no electrostimulation included (NEA). Methods: A retrospective observational study was conducted using electronic health records of acupuncture sessions for adults with acute pain under the care of an acute pain service. Paired t-test and linear regression were used to report pain intensity changes after a single acupuncture session and by including EA. Ordered logistic regression was used to report categorical pain relief. Logistic regression was used to explore the odds of adding EA and the patient's age, gender, and pretreatment pain. Results: From July 24, 2017, through November 9, 2020, 465 acupuncture sessions recorded EA (n = 194), or NEA (n = 271). Acupuncture, independent of EA status, reduced pain intensity by a mean 2.5 points. EA was associated with a mean 0.38-point reduction in pain intensity more than NEA (confidence interval [95% CI]: -0.75 to -0.01). Among sessions reporting categorical pain relief (n = 415), higher relief was more likely with EA (odds ratio = 2.16, 95% CI: 1.52-3.08). There was no association between EA and the patient's age, gender, and pretreatment pain intensity. Conclusions: After a single acupuncture session, both EA and NEA reduced pain intensity. Higher categorical pain relief was reported with EA, though the clinical meaning is uncertain. Future research should focus on well-defined populations for electroacupuncture and factors for including electrostimulation.

RESUMO

BACKGROUND: Incorrect condom use is a common problem that can undermine their prevention impact. We assessed the prevalence of 2 condom use problems, breakage/slippage and partial use, compared problems by partnership type, and examined associations with respondent, partner, and partnership characteristics. METHODS: Data were collected at 3-month intervals during a 12-month period (1999-2000) among urban sexually transmitted disease (STD) clinic users. Condom use problems were compared between partnership types using z tests for equality of proportions. Logistic generalized estimating equations modeling accounted for within-participant correlation of repeated measures. RESULTS: Overall 3297 respondents reported 9304 main and 6793 non-main partnerships; condoms were used at least once in 4942 (53.0%) and 4523 (66.6%) of these partnerships, respectively. Condom breakage/slippage was reported during 6.0% of uses (5.1% main, 9.4% non-main) and partial use during 12.5% of uses (12.8% main, 11.5% non-main). The proportion of respondents experiencing any condom use problem in the prior 3 months was higher among main compared with non-main partnerships: 39.1% versus 29.9% had either problem; 22.5% versus 19.0% had breakage/slippage only; 21.8% versus 18.7% had partial use; and 8.7% versus 7.1% had both use problems. In multivariable analysis, factors associated with condom use problems varied by partnership type and respondent sex. The most common predictors of problems across models were sex while high and inconsistent condom use. CONCLUSIONS: This study highlights the diverse set of risk factors for condom use problems at the individual, partner, and partnerships levels.

RESUMO

In many sub-Saharan African countries, a high proportion of people living with HIV are in long-term serodiscordant relationships. This paper explores how HIV serodiscordance shapes communication among couples in long-term HIV-serodiscordant relationships. A total of 36 couples were purposively recruited through healthcare providers and civil society organisations in South Africa (26) and Tanzania (10). We explored couples' portrayal of living in a serodiscordant relationship by conducting semi-structured interviews with each partner separately, followed by a joint interview with both partners. Using an adaptation of Persson's model on sero-silence and sero-sharing, we categorised coping style as 'sero-silent' if partners reported that they did not talk much with each other about issues related to their serodiscordant status or as 'sero-sharing' if they portrayed HIV as being an issue which they dealt with together. Some couples exhibited features of both coping styles and, at times, partners differed in their ways of coping.

RESUMO

Objective: Evidence of effectiveness and demand for acupuncture to treat acute pain conditions is growing, as is the need for acupuncturists trained to deliver patient care in a hospital setting. This articles describes collaboration between Bastyr University and Harborview Medical Center to incorporate Doctor of Acupuncture and Oriental Medicine (DAOM) students into a trauma hospital setting. Materials and Methods: A model was developed to integrate DAOM students into an Anesthesiology Acute Pain Service to provide acupuncture to postoperative inpatients. That in-person model pivoted to remote student education and patient self-care education during the COVID 19 outbreak. A review was conducted of 323 consecutive patients who received acupuncture while they were hospitalized. Results: The review of 323 consecutive patients who received acupuncture for pain during their hospital admission indicated that as few as one acupuncture treatment resulted in clinically significant benefits. No serious complications or safety concerns were reported. Conclusions: Collaboration between academic and clinical programs can provide the structure to integrate acupuncture into hospital settings safely and with benefit to patients and students.

RESUMO

OBJECTIVES: Literature supporting best practice of perioperative buprenorphine management for opioid use disorder is evolving with more recent studies trending toward maintenance of home dose. To guide treatment protocols at our institution, we evaluated patients taking medication for opioid use disorder (MOUD) undergoing similar surgeries. Patients were maintained on either their outpatient buprenorphine or methadone. PATIENTS AND PARTICIPANTS: Data were collected on 46 patients maintained on buprenorphine MOUD who underwent surgery. A subset of these patients (n = 24) was compared with 24 patients maintained on methadone MOUD, matched on surgical procedure, admission date, age, and sex. DESIGN: This is a retrospective matched control study. SETTING: An academic, tertiary, Level 1 trauma center. MAIN OUTCOME MEASURES: Primary outcomes were post-operative opioid use and post-anesthesia care unit (PACU) length of stay. RESULTS: No significant differences in demographic characteristics, physical status, comorbid psychiatric diagnoses, or illicit substance use history were observed between patient groups. A higher proportion of patients taking methadone was admitted due to infection (41.7 percent vs 16.7 percent, p = 0.031) and underwent nonelective surgery (75.0 percent vs 45.8 percent, p = 0.039). No significant differences were observed between patients taking buprenorphine versus methadone with respect to PACU length of stay, post-operative opioid consumption, time-to-transition to oral opioids, or discharge opioid prescriptions. Patients taking buprenorphine were more likely to receive intravenous lidocaine (25.0 percent vs 0.0 percent, p = 0.031) and ketamine (83.3 percent vs 54.2 percent, p = 0.039). CONCLUSION: Findings from this study support accumulating evidence that patients should be maintained on buprenorphine MOUD throughout the perioperative period.

RESUMO

This article reports on the influence of HIV on sexual relations and childbearing decisions of 36 HIV-discordant couples, 26 in South Africa and 10 in Tanzania, recruited into an exploratory study through hospital antiretroviral treatment clinics and civil society organisations working with people living with HIV. Self-administered questionnaires were used to obtain social and demographic information, while couples' sexual relations and childbearing decisions were explored through in-depth, semi-structured individual and couple interviews. The majority of the HIV-positive partners were women, who were on antiretroviral treatment. Almost one-third of South African respondents and half of those in Tanzania reported experiences of tension related to HIV-discordance, while more than half of the South Africans and almost three-quarters of the Tanzanians reported that intimacy had been affected by their discordant status. Those without children were more likely to desire children (17/23) than those who already had children (16/44), although this desire was influenced by fear of HIV transmission to the negative partner and medical professional advice. The study points to the need for targeted information for HIV discordant couples, as well as couple counselling and support services.

RESUMO

Although the HIV epidemic among men who have sex with men (MSM) in South Africa preceded the onset of the generalised HIV epidemic by several years, current policies and programmes focus on heterosexual transmission and mother-to-child transmission. We used an adaptation of the UNAIDS Country Harmonised Alignment Tool (CHAT) to assess whether existing HIV policies and programmes in South Africa address the needs of MSM. This covered mapping of key risk factors and epidemiology of HIV among MSM; participation of MSM in the HIV response; and an enabling environment for service provision, funding and human resources. We found that current policies and programmes are unresponsive to the needs of MSM and that epidemiologic information is lacking, in spite of policy on MSM in the National Strategic Plan. We recommend that government initiate sentinel surveillance to determine HIV prevalence among MSM, social science research on the contexts of HIV transmission among MSM, and appropriate HIV prevention and care strategies. MSM should be closely involved in the design of policies and programmes. Supportive programme development should include dedicated financial and human resources, appropriate guidelines, and improved access to and coverage of HIV prevention, treatment and care services for MSM.

RESUMO

INTRODUCTION: HIV self-testing (HIVST) offers a useful addition to HIV testing services and enables individuals to test privately. Despite recommendations to the contrary, repeat HIV testing is frequent among people already on anti-retroviral treatment (ART) and there are concerns that oral self-testing might lead to false negative results. A study was conducted in Khayelitsha, South Africa, to assess feasibility and uptake of HIVST and linkage-to-care following HIVST. METHODS: Participants were recruited at two health facilities from 1 March 2016 to 31 March 2017. People under 18 years, or with self-reported previously-diagnosed HIV infection, were excluded. Participants received an OraQuick Rapid HIV-1/2 Antibody kit, and reported their HIVST results by pre-paid text message (SMS) or by returning to the facility. Those not reporting within 7 days were contacted by phone. Electronic and paper-based clinical and laboratory records were retrospectively examined for all participants to identify known HIV outcomes, after matching for name, date of birth, and sex. These findings were compared with self-reported HIVST results where available. RESULTS: Of 639 participants, 401 (62.8%) self-reported a negative HIVST result, 27 (4.2%) a positive result, and 211 (33.0%) did not report. The record search identified that of the 401 participants self-reporting a negative HIVST result, 19 (4.7%) were already known to be HIV positive; of the 27 self-reporting positive, 12 (44%) were known HIV positive. Overall, records showed 57/639 (8.9%) were HIV positive of whom 39/57 (68.4%) had previously-diagnosed infection and 18/57 (31.6%) newly-diagnosed infection. Of the 428 participants who self-reported a result, 366 (85.5%) reported by SMS. CONCLUSIONS: HIVST can improve HIV testing uptake and linkage to care. SMS is acceptable for reporting HIVST results but negative self-reports by participants may be unreliable. Use of HIVST by individuals on ART is frequent despite recommendations to the contrary and its implications need further consideration.

RESUMO

OBJECTIVE: Inform readers of the use of a clinical pathway that includes initiation of methadone in hospitalized patients with acute pain who have untreated opioid use disorder (OUD). DESIGN: A retrospective chart review with frequency distributions and descriptive statistics calculated to describe demo-graphic and clinical characteristics of the sample. SETTING: Urban academic hospital. PATIENTS: One hundred twenty consecutive patients with untreated OUD cared for by the Acute Pain Service (APS). INTERVENTIONS: APS leadership spearheaded development of a clinical pathway to standardize pain management and optimize outcomes. The authors outline pathway development and describe 120 patients managed using this pathway, initiated on methadone for OUD. RESULTS: The sample included patients, average age 40 years, predominantly non-Hispanic white (74.2 percent), male (61.7 percent), unemployed (88.2 percent), and on Medicaid (84.2 percent). 96.7 percent had a history of heroin use, and 52.1 percent had engaged in previous medication-assisted treatment (MAT). Methadone or other opioids were held for signs of intoxication/sedation in 10.9 percent or for prolonged corrected QT interval in 1.7 percent. The majority received at least one other analgesic agent. For those prescribed opioids upon discharge, the average maximum morphine equivalent dose was 68.2 mg/day for approximately 3 days. 68.3 percent agreed to schedule post-discharge MAT, and of these, 68 percent attended their intake appointment. A small percentage (4.7 percent) left the hospital against medical advice. CONCLUSION: This pathway provides an example of an effective and safe response to address the opioid epidemic and pro-vide quality care to patients with OUD and pain.

RESUMO

OBJECTIVES: To describe heterosexual anal sex activity during a year and to identify factors associated with heterosexual anal sex and condom use during anal sex. METHODS: Secondary analysis of data from a trial conducted in 3 public sexually transmitted disease (STD) clinics. Patients described sexual behaviors every 3-months for the year. Logistic regression models with generalized estimating equations were used to include multiple observations for each subject. RESULTS: Two thousand three hundred fifty-seven heterosexual subjects reported on 6611 3-month intervals that included 9235 partnerships. About 18.3% of subjects had anal sex in a particular 3-month interval and 39.3% in the year. About 23.5% of subjects had anal sex in at least two 3-month intervals in the year. Anal sex was associated with having more sex acts, 2 or more sex partners, unprotected vaginal sex, and a main partner. For anal sex in the past 3 months, 27.3% of subjects consistently used condoms, and 63% of subjects never used condoms. Consistent condom use for anal sex was associated with having consistent condom use for vaginal sex, 2 or more partners, and anal sex with casual or new partner. CONCLUSION: STD clinic patients were commonly engaged in heterosexual anal sex, and most of them never used condoms during anal sex. Patients who had anal sex tended to also engage in other risk behaviors that put them at risk of STD/human immunodeficiency virus. Clinicians should ask about anal sex, appropriately examine and test patients who have had anal sex, and recommend condom use for both anal and vaginal sex.

RESUMO

BACKGROUND: HIV Viral Load and Early Infant Diagnosis technologies in many high burden settings are restricted to centralized laboratory testing, leading to long result turnaround times and patient attrition. GeneXpert (Cepheid, CA, USA) is a polyvalent near point-of-care platform and is widely implemented for Xpert MTB/RIF diagnosis. This study sought to evaluate the operational feasibility of integrated HIV VL, EID and MTB/RIF testing in new GeneXpert platforms. METHODS: Whole blood samples were collected from consenting patients due for routine HIV VL testing and DBS samples from infants due for EID testing, at three rural health facilities in Zimbabwe. Sputum samples were collected from all individuals suspected of TB. GeneXpert testing was reserved for all EID, all TB suspects and priority HIV VL at each site. Blood samples were further sent to centralized laboratories for confirmatory testing. GeneXpert polyvalent testing results and patient outcomes, including infrastructural and logistical requirements are reported. The study was conducted over a 10-month period. RESULTS: The fully automated GeneXpert testing device, required minimal training and biosafety considerations. A total of 1,302 HIV VL, 277 EID and 1,581 MTB/RIF samples were tested on a four module GeneXpert platform in each study site. Xpert HIV-1 VL testing was prioritized for patients who presented with advanced HIV disease, pregnant women, adolescents and suspected ART failures patients. On average, the study sites had a GeneXpert utilization rate of 50.4% (Gutu Mission Hospital), 63.5% (Murambinda Mission Hospital) and 17.5% (Chimombe Rural Health Centre) per month. GeneXpert polyvalent testing error rates remained lower than 4% in all sites. Decentralized EID and VL testing on Xpert had shorter overall median TAT (1 day [IQR: 0-4] and 1 day [IQR: 0-1] respectively) compared to centralized testing (17 days [IQR: 13-21] and 26 days [IQR: 23-32] respectively). Among patients with VL >1000 copies/ml (73/640; 11.4%) at GMH health facility, median time to enhanced adherence counselling was 8 days and majority of those with documented outcomes had re-suppressed VL (20/32; 62.5%). Median time to ART initiation among Xpert EID positive infants at GMH was 1 day [IQR: 0-1]. CONCLUSION: Implementation of near point-of-care GeneXpert platform for integrated multi-disease testing within district and sub-district healthcare settings is feasible and will increase access to VL, and EID testing to priority populations. Quality management systems including monitoring of performance indicators, together with regular on-site supervision are crucial, and near-POC test results must be promptly actioned-on by clinicians for patient management.

RESUMO

BACKGROUND: Studies show 11% to 15% of women treated for Chlamydia trachomatis are reinfected 3 to 4 months after treatment, suggesting the need for rescreening. There is little information on infections among men, infections with Neisseria gonorrhoeae or Trichomonas vaginalis, or long-term follow-up. OBJECTIVE: To determine the incidence of new sexually transmitted infections during the year after a visit to a sexually transmitted disease (STD) clinic and associated risk factors. DESIGN: Secondary analysis of data from a randomized, controlled trial (RESPECT-2). SETTING: 3 urban STD clinics. PATIENTS: Sexually active patients enrolled in an HIV prevention counseling trial. MEASUREMENTS: Patient characteristics at the initial visit; behaviors during follow-up; and new infections with C. trachomatis, N. gonorrhoeae, or T. vaginalis (women only) detected during 4 scheduled return visits and any other interim visits. RESULTS: 2419 persons had 8129 three-month follow-up intervals. Among 1236 women, 25.8% had 1 or more new infections (11.9% acquired C. trachomatis, 6.3% acquired N. gonorrhoeae, and 12.8% acquired T. vaginalis); among 1183 men, 14.7% had 1 or more new infections (9.4% acquired C. trachomatis, and 7.1% acquired N. gonorrhoeae). Black persons and those with sexually transmitted infections at baseline were at highest risk for recurrent infection (adjusted odds ratio, 2.5 and 2.4, respectively). For persons infected at baseline, the risk for infection was high at 3 and 6 months (16.3 per 100 three-month intervals) and remained high at 9 and 12 months (12.0 per 100 three-month intervals). Most (67.2%) infections were diagnosed during study-related visits, and 66.2% of these patients reported no symptoms. LIMITATIONS: Because patients were recruited from STD clinics, results may not be generalizable. CONCLUSIONS: Men and women who receive diagnoses of C. trachomatis, N. gonorrhoeae, or T. vaginalis infections should return in 3 months for rescreening because they are at high risk for new asymptomatic sexually transmitted infections. Although single-dose therapy may adequately treat the infection, it often does not adequately treat the patient.

RESUMO

OBJECTIVES: Estimate the effect of participation in Community ART Groups (CAG) versus individual care on retention-in-care (RIC) on antiretroviral therapy (ART). DESIGN: Retrospective cohort study. SETTING: High levels of attrition (death or loss-to-follow-up (LTFU) combined) on ART indicate that delivery models need to adapt in sub-Saharan Africa. In 2008, patients more than 6 months on ART began forming CAG, and took turns to collect ART refills at the health facility, in Tete Province, Mozambique,. PARTICIPANTS: 2406 adult patients, retained in care for at least 6 months after starting ART, during the study period (date of CAG introduction at the health facility-30 April 2012). METHODS: Data up to 30 April 2012 were collected from patient records at eight health facilities. Survival analysis was used to compare RIC among patients in CAG and patients in individual care, with joining a CAG treated as an irreversible time-dependent variable. Multivariable Cox regression was used to estimate the effect of CAG on RIC, adjusted for age, sex and health facility type and stratified by calendar cohort. RESULTS: 12-month and 24-monthRIC from the time of eligibility were, respectively, 89.5% and 82.3% among patients in individual care and 99.1% and 97.5% among those in CAGs (p<0.0001). CAG members had a greater than fivefold reduction in risk of dying or being LTFU (adjusted HR: 0.18, 95% CI 0.11 to 0.29). CONCLUSIONS: Among patients on ART, RIC was substantially better among those in CAGs than those in individual care. This study confirms that patient-driven ART distribution through CAGs results in higher RIC among patients who are stable on ART.

RESUMO

INTRODUCTION: In 2012 Community ART Groups (CAGs), a community-based model of antiretroviral therapy (ART) delivery were piloted in Thyolo District, Malawi as a way to overcome patient barriers to accessing treatment, and to decrease healthcare workers' workload. CAGs are self-formed groups of patients on ART taking turns to collect ART refills for all group members from the health facility. We conducted a qualitative study to assess the benefits and challenges of CAGs from patients' and healthcare workers' (HCWs) perspectives. METHODS: Data were collected by means of 15 focus group discussions, 15 individual in-depth interviews, and participant observation in 2 health centres. The 94 study participants included CAG members, ART patients eligible for CAGs who remained in conventional care, former CAG members who returned to conventional care and HCWs responsible for providing HIV care. Patient participants were purposively selected from ART registers, taking into account age and gender. Narratives were audio-recorded, transcribed, and translated from Chichewa to English. Data were analyzed through a thematic analysis. RESULTS: Patients and HCWs spoke favourably about the practical benefits of CAGs. Patient benefits included a reduced frequency of clinic visits, resulting in reduced transportation costs and time savings. HCW benefits included a reduced workload. Additionally peer support was perceived as an added value of the groups allowing not only sharing of the logistical constraints of drugs refills, but also enhanced emotional support. Identified barriers to joining a CAG included a lack of information on CAGs, unwillingness to disclose one's HIV status, change of residence and conflicts among CAG members. Participants reported that HIV-related stigma persists and CAGs were seen as an effective strategy to reduce exposure to discriminatory labelling by community members. CONCLUSION: In this setting, patients and HCWs perceived CAGs to be an acceptable model of ART delivery. Despite addressing important practical barriers to accessing ART, and providing peer support, CAGs were not well known by patients and had a limited impact on reducing HIV-related stigma. The CAG model of ART delivery should be considered in similar settings. Further measures need to be devised and implemented to address HIV-related stigma.

RESUMO

In HIV-discordant relationships, the HIV-negative partner also carries the burden of a stigmatised disease. For this reason, couples often hide their HIV-discordant status from family, friends and community members. This perpetuates the silence around HIV-discordant relationships and impacts on targeted HIV prevention, treatment and counselling efforts. This article reports on experiences of stigma and discrimination among HIV-discordant couples in South Africa, Tanzania and Ukraine. During 2008, HIV-discordant couples who had been in a relationship for at least one year were recruited purposively through health-care providers and civil society organisations in the three countries. Participants completed a brief self-administered questionnaire, while semi-structured interviews were conducted with each partner separately and with both partners together. Interviews were analysed using thematic content analysis. Fifty-one couples were recruited: 26 from South Africa, 10 from Tanzania, and 15 from Ukraine. Although most participants had disclosed their HIV status to someone other than their partner, few were living openly with HIV discordance. Experiences of stigma were common and included being subjected to gossip, rumours and name-calling, and HIV-negative partners being labelled as HIV-positive. Perpetrators of discrimination included family members and health workers. Stigma and discrimination present unique and complex challenges to couples in HIV sero-discordant relationships in these three diverse countries. Addressing stigmatisation of HIV-discordant couples requires a holistic human rights approach and specific programme efforts to address discrimination in the health system.
