RESUMEN
BACKGROUND: Despite HIV's evolution to a chronic disease, the burden of advanced HIV disease (AHD, defined as a CD4 count of < 200 cells/uL or WHO clinical Stage 3 or 4 disease), remains high among People Living with HIV (PLHIV) who have previously been prescribed antiretroviral therapy (ART). As little is known about the experiences of patients hospitalised with AHD, this study sought to discern social forces driving hospitalisation with AHD. Understanding such forces could inform strategies to reduce HIV-related morbidity and mortality. METHODS: We conducted a qualitative study with patients hospitalised with AHD who had a history of poor adherence. Semi-structured interviews were conducted between October 1 and November 30, 2023. The Patient Health Engagement and socio-ecological theoretical models were used to guide a thematic analysis of interview transcripts. RESULTS: Twenty individuals participated in the research. Most reported repeated periods of disengagement with HIV services. The major themes identified as driving disengagement included: 1) feeling physically well; 2) life circumstances and relationships; and 3) health system factors, such as clinic staff attitudes and a perceived lack of flexible care. Re-engagement with care was often driven by new physical symptoms but was mediated through life circumstances/relationships and aspects of the health care system. CONCLUSIONS: Current practices fail to address the challenges to lifelong engagement in HIV care. A bold strategy for holistic care which involves people living with advanced HIV as active members of the health care team (i.e. 'PLHIV as Partners'), could contribute to ensuring health care services are compatible with their lives, reducing periods of disengagement from care.

BACKGROUND: There have been calls for "person-centered" approaches to drug-resistant tuberculosis (DR-TB) care. In 2020, Charles James Hospital in South Africa, which incorporated person-centered care, was closed. Patients were referred mid-course to a centralized, tertiary hospital, providing an opportunity to examine person-centered DR-TB and HIV care from the perspective of patients who lost access to it. METHODS: The impact of transfer was explored through qualitative interviews performed using standard methods. Analysis involved grounded theory; interviews were assessed for theme and content. RESULTS: After switching to the centralized site, patients reported being unsatisfied with losing access to a single clinic and pharmacy where DR-TB, HIV and chronic disease care were integrated. Patients also reported a loss of care continuity; at the decentralized site there was a single, familiar clinician whereas the centralized site had multiple, changing clinicians and less satisfactory communication. Additionally, patients reported more disease-related stigma and less respectful treatment, noting the loss of a "special place" for DR-TB treatment. CONCLUSION: By focusing on a DR-TB clinic closure, we uncovered aspects of person-centered care that were critical to people living with DR-TB and HIV. These perspectives can inform how care for DR-TB is operationalized to optimize treatment retention and effectiveness.

BACKGROUND: In decentralized sites, with fewer resources and a high prevalence of advanced HIV, the effectiveness of the new short-course, bedaquiline-based regimen for rifampicin-resistant and multidrug-resistant tuberculosis (RR/MDR-TB) is not well-described. SETTING: Adults with pulmonary RR/MDR-TB initiating the short-course regimen in KwaZulu-Natal, South Africa were prospectively enrolled at a decentralized program that integrated person-centered TB care. METHODS: In addition to standard of care monitoring, study visits occurred at enrollment and months 1, 2, 4, 6, and 9. Favorable RR/MDR-TB outcome was defined as cure or treatment completion without loss to follow-up, death, or failure by treatment. In patients with HIV, we assessed antiretroviral therapy (ART) uptake, virologic and immunologic outcomes. RESULTS: Among 57 patients, HIV was present in 73.7% (95% CI: 60.3-84.5), with a median CD4 count of 170 cells/mm 3 (intraquartile range 49-314). A favorable RR/MDR-TB outcome was achieved in 78.9% (CI: 67.1-87.9). Three deaths occurred, all in the setting of baseline advanced HIV and elevated viral load. Overall, 21.1% (95% CI: 12.1-32.9) experienced a severe or life-threatening adverse event, the most common of which was anemia. Among patients with HIV, enrollment resulted in increased ART uptake by 24% (95% CI: 12.1%-39.4%), a significant improvement from baseline ( P = 0.004); virologic suppression during concomitant treatment was observed in 71.4% (n = 30, 95% CI: 55.4-84.3). CONCLUSION: Decentralized, person-centered care for RR/MDR-TB in patients with HIV using the short-course, bedaquiline-based regimen is effective and safe. In patients with HIV, enrollment led to improved ART use and reassuring virologic outcomes.

The elimination of new HIV infections in infants and children is part of a broader global commitment by the United Nations. Prevention of Mother to Child transmission (PMTCT) programmes have prevented 350,000 new HIV infections with the use of antiretroviral therapy (ARVs) for pregnant women who are HIV infected, and the majority of these gains were in sub-Saharan Africa. Coverage of PMTCT programmes throughout Africa is variable resulting in many women not having access to the appropriate interventions in the antenatal care setting to prevent vertical transmission. The global elimination target requires a 90% reduction of new child infections and to decrease MTCT to <5% which potentially can be achieved utilising the four pronged approach proposed by the World Health Organization. Family planning messages and provision of contraception methods to avoid unplanned pregnancies are shown to be more effective than HIV Counselling and Testing [HCT] and single dose Nevirapine in averting transmission of perinatal HIV infection. Child survival goes beyond HIV-free survival and safe breastfeeding prevents 13% of deaths under 5 years of age rendering it essential to reduce under-5 mortality. Health systems strengthening to deliver more complex regimens either for prevention purposes or the mothers own health is an important part of a broader continuum of interventions which will depend on the effective delivery of current treatment modalities, development of new prevention interventions including a vaccine, and include prevention of unplanned pregnancies and primary prevention of HIV infections in the mother.

BACKGROUND: There is paucity of information on the cost-effectiveness of delivery strategies to retain patients on antiretroviral therapy (ART) and this study tries to fill this gap. METHODS: The analysis is based on a representative sample of 2835 patients attending 32 ART sites in KwaZulu-Natal (KZN), South Africa. Extended Cox regression and Kaplan Meier were used to estimate the transition probabilities to remain on ART among patients who attended sites with different staff and workload profiles. Annual costs per patient-year of observation for these delivery profiles were estimated. Probabilistic sensitivity analysis took into account parameters' uncertainty. RESULTS: The delivery sites with a full-time doctor and a full-time senior professional nurse and an intake of less than 200 new patients per doctor per year were the most cost-effective in retaining patients on ART. If 1000 new patients were followed up by this type of site, 724 patients would still be on ART after 10 years at a discounted cost of US$8.41 million at 2006 value with an incremental cost-effectiveness ratio of US$12,271 per extra retained patient over the second not dominated site profile. CONCLUSIONS: The results could be used to estimate the human resources needed for a sustainable scaling up of ART in KZN.

OBJECTIVE: To analyze the critical factors favoring the retention of patients under antiretroviral therapy (ART) in KwaZulu-Natal (KZN), South Africa. DESIGN AND METHODS: This retrospective study was based on the review of a representative sample of patients who began ART between March 2004 and May 2006 in 32 public sector sites and were followed up to July 1, 2007. Extended Cox proportional hazard models were used to identify the factors which significantly influenced treatment retention during the first 2 years of treatment. Kaplan-Meyer provided the probabilities of remaining on ART if these factors were present. RESULTS: The 2835 sampled patients corresponded to about 10% of the universe of patients under ART in the 32 sites; 929 (33%) were males, and the median age of the sampled patients was 34 (interquartile range: 28-41). The analysis identified factors that significantly decreased the probability of remaining on ART. Patients' risk factors were initial CD4 <100 cells per microliter, lack of a telephone contact number, and being male. Sites' risk factors were the presence of a part time (PT) versus a full time (FT) senior professional nurse, a PT versus FT doctor, and intakes of 200 or more new patients per doctor per year. The probability of remaining on ART declined significantly for each increasing level of workload, but having a FT versus a PT doctor made a significant difference only for level of workload of 200 or more new patients per year. CONCLUSIONS: The analysis has identified the conditions influencing retention of ART patients in KZN. This has provided a method to estimate absorption capacity of the ART delivery sites, which is of added value for a sustainable expansion of the ART coverage.

BACKGROUND: The epidemics of HIV-1 and tuberculosis in South Africa are closely related. High mortality rates in co-infected patients have improved with antiretroviral therapy, but drug-resistant tuberculosis has emerged as a major cause of death. We assessed the prevalence and consequences of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis in a rural area in KwaZulu Natal, South Africa. METHODS: We undertook enhanced surveillance for drug-resistant tuberculosis with sputum culture and drug susceptibility testing in patients with known or suspected tuberculosis. Genotyping was done for isolates resistant to first-line and second-line drugs. RESULTS: From January, 2005, to March, 2006, sputum was obtained from 1539 patients. We detected MDR tuberculosis in 221 patients, of whom 53 had XDR tuberculosis. Prevalence among 475 patients with culture-confirmed tuberculosis was 39% (185 patients) for MDR and 6% (30) for XDR tuberculosis. Only 55% (26 of 47) of patients with XDR tuberculosis had never been previously treated for tuberculosis; 67% (28 of 42) had a recent hospital admission. All 44 patients with XDR tuberculosis who were tested for HIV were co-infected. 52 of 53 patients with XDR tuberculosis died, with median survival of 16 days from time of diagnosis (IQR 6-37) among the 42 patients with confirmed dates of death. Genotyping of isolates showed that 39 of 46 (85%, 95% CI 74-95) patients with XDR tuberculosis had similar strains. CONCLUSIONS: MDR tuberculosis is more prevalent than previously realised in this setting. XDR tuberculosis has been transmitted to HIV co-infected patients and is associated with high mortality. These observations warrant urgent intervention and threaten the success of treatment programmes for tuberculosis and HIV.
