RESUMO

The co-occurrence of human immunodeficiency virus and malaria presents a complex medical scenario, significantly impacting the quality of life for affected individuals. This comprehensive review synthesizes current knowledge, challenges, and strategies concerning the concurrent management of these infections to improve overall well-being. Epidemiological insights reveal the prevalence and demographic trends, highlighting geographical areas of concern and socioeconomic factors contributing to the burden of co-infection. Pathophysiological interactions elucidate the compounding effects, altering disease progression and treatment outcomes. Healthcare challenges underscore the necessity for integrated care models, evaluating existing healthcare frameworks and their efficacy in addressing dual infections. In-depth analysis of interventions explores pharmacological, behavioral, and preventive measures, evaluating their efficacy and safety in co-infected individuals. Additionally, the review assesses psychosocial support mechanisms, emphasizing community-based interventions and peer networks in enhancing holistic care. Consideration is given to the role of antiretroviral therapy, malaria prevention strategies, and the evolving landscape of healthcare delivery in optimizing outcomes for this vulnerable population. The paper concludes by emphasizing the significance of multidisciplinary approaches and integrated care models, stressing the need for continued research and collaborative efforts to advance interventions and improve the quality of life for those navigating the complexities of human immunodeficiency virus and malaria co-infection.

RESUMO

INTRODUCTION: Sub-Saharan Africa continues to experience a syndemic of HIV and non-communicable diseases (NCDs). Vertical (stand-alone) HIV programming has provided high-quality care in the region, with almost 80% of people living with HIV in regular care and 90% virally suppressed. While integrated health education and concurrent management of HIV, hypertension and diabetes are being scaled up in clinics, innovative, more efficient and cost-effective interventions that include decentralisation into the community are required to respond to the increased burden of comorbid HIV/NCD disease. METHODS AND ANALYSIS: This protocol describes procedures for a process evaluation running concurrently with a pragmatic cluster-randomised trial (INTE-COMM) in Tanzania and Uganda that will compare community-based integrated care (HIV, diabetes and hypertension) with standard facility-based integrated care. The INTE-COMM intervention will manage multiple conditions (HIV, hypertension and diabetes) in the community via health monitoring and adherence/lifestyle advice (medicine, diet and exercise) provided by community nurses and trained lay workers, as well as the devolvement of NCD drug dispensing to the community level. Based on Bronfenbrenner's ecological systems theory, the process evaluation will use qualitative methods to investigate sociostructural factors shaping care delivery and outcomes in up to 10 standard care facilities and/or intervention community sites with linked healthcare facilities. Multistakeholder interviews (patients, community health workers and volunteers, healthcare providers, policymakers, clinical researchers and international and non-governmental organisations), focus group discussions (community leaders and members) and non-participant observations (community meetings and drug dispensing) will explore implementation from diverse perspectives at three timepoints in the trial implementation. Iterative sampling and analysis, moving between data collection points and data analysis to test emerging theories, will continue until saturation is reached. This process of analytic reflexivity and triangulation across methods and sources will provide findings to explain the main trial findings and offer clear directions for future efforts to sustain and scale up community-integrated care for HIV, diabetes and hypertension. ETHICS AND DISSEMINATION: The protocol has been approved by the University College of London (UK), the London School of Hygiene and Tropical Medicine Ethics Committee (UK), the Uganda National Council for Science and Technology and the Uganda Virus Research Institute Research and Ethics Committee (Uganda) and the Medical Research Coordinating Committee of the National Institute for Medical Research (Tanzania). The University College of London is the trial sponsor. Dissemination of findings will be done through journal publications and stakeholder meetings (with study participants, healthcare providers, policymakers and other stakeholders), local and international conferences, policy briefs, peer-reviewed journal articles and publications. TRIAL REGISTRATION NUMBER: ISRCTN15319595.

RESUMO

Psoriasis is a chronic inflammatory disease that can often accompany human immunodeficiency virus (HIV) epidemics. Development of psoriasis in HIV patients is correlated with a decrease in CD4+ count. Significant variability in the clinical presentation of psoriasis makes it a challenging disease to diagnose. Furthermore, associated immunodeficiency complicates standard treatment with immunosuppressive and biological therapy. Articles that match the terms psoriasis and HIV were searched in MEDLINE and Embase and selected based on their relevance. Highly active antiretroviral therapy (HAART) is a medication regimen used to manage and treat HIV infection. In treating mild psoriasis in HIV-positive patients, topical agents combined with HAART are considered first-line therapy, followed by phototherapy. Second-line therapy includes oral retinoids, alone or combined. In treating challenging cases, apremilast has been used due to its lack of immunosuppressive effect. In case of progressive and refractory disease, limited data from studies suggest that immunosuppressive or biological therapy may be effective. Treatment of psoriasis in HIV patients remains a challenge, which is largely attributable to its complicated etiopathology and lack of an approved therapy option. In treating severe psoriasis, close collaboration with an infectious disease specialist is highly recommended. Further research is needed, preferably with an aim toward developing individualized therapy.

RESUMO

BACKGROUND: Integrated health care is an approach characterized by a high degree of collaboration and communication among health professionals. Integration of HIV/NCD is recommended to enhance the quality of healthcare services being provided. Duplication of limited resources is minimized, and a holistic care approach is promoted by shifting from acute and reactive care to care that embraces patient-centredness that includes promotive health and disease surveillance. The high burden of HIV disease in sub-Saharan Africa (SSA) combined with the increasing prevalence of chronic non-communicable diseases (NCDs) necessitates a review of how health systems has been doing to deliver quality integrated care for people living with HIV (PLWH) and comorbid chronic NCDs. METHODS: A scoping review was conducted to identify and describe all publications on integrated chronic care management models at the primary care level in the SSA context, particularly those that addressed the care of PLHIV with co-morbid chronic NCDs. The inclusion and exclusion criteria were applied, and duplicates were removed. RESULTS: A total of twenty-one articles were included in the final review. Integrated healthcare systems were reported in only eight SSA countries-(South Africa, Uganda, Kenya, the United Republic of Tanzania, Zambia, Malawi, Zimbabwe and Swaziland). Integrated care systems adopted one of three health models. These included added-on NCD services to previously dedicated HIV care facilities, expansion of primary care facilities to include HIV care and establishment of integrated care services. Short-term benefits included staff capacitation, improved retention of patients and improved screening and detection of NCDs. However, the expansion of existing services resulted in an increased workload with no additional staff. A significant positive change noted by communities was that there was less or no stigmatisation of people living with HIV when attending dedicated HIV clinics. CONCLUSION: Evidence of integrated healthcare services for PLWH and co-morbid of NCDs in SSA is scanty. Data on some short-term benefits of integrated care was available, but evidence was absent on the long-term outcomes. Randomized clinical trials with clearly defined comparator groups and standardized measures of HIV and NCD outcomes are needed to demonstrate non-inferiority of integrated against non-integrated care.

RESUMO

Background: Vitamin D deficiency (VDD) is a worldwide disease. VDD is also associated with an increased risk of HIV-related comorbidities and mortality, and patients have a tendency to develop active tuberculosis compared to those with latent tuberculosis infection. Vitamin D supplementation may modulate HIV replication, improve TB inflammation and reduce progression of HIV-TB co-infection. Methods: We meta-analyzed individual participant data from cohort studies, cross-sectional study, and RCTs of vitamin D in HIV group, TB group, and HIV-TB group. The primary outcomes were differences in vitamin D level and VDD prevalence between three groups, the secondary outcomes were CD4 count, HIV viral load, time to sputum smear conversion, time to culture conversion, relapse, morality, and TB score. Results: For vitamin D levels, the overall mean difference (MD) between HIV group and TB group was -0.21 (95% CI, -20.80-20.38; p = 0.9, I2 = 84%), HIV group and HIV-TB group was 0.87 (95% CI, -11.45-13.20; p = 0.89, I2 = 87%), and TB group and HIV-TB group was 1.17 (95% CI, -5.21-7.55; p = 0.72, I2 = 85%). For vitamin D deficiency prevalence, the overall odds ratio (OR) for HIV group versus TB group was 1.23 (95% CI, 0.46-3.31; p = 0.68; I2 = 70%), HIV group versus HIV-TB group was 1.53 (95% CI, 1.03-2.29; p = 0.04; I2 = 0%), and TB group versus HIV-TB group was 0.85 (95% CI, 0.61-1.20; p = 0.36; I2 = 22%). In HIV-TB group, the overall OR for vitamin D group versus placebo group was 0.78 (95% CI, 0.34-1.67; p = 0.52; I2 = 60%). Conclusion: Our findings indicated that there were no variations in vitamin D levels between three groups. The prevalence of vitamin D deficiency was higher in the HIV-TB group than in the HIV group. Additionally, the administration of vitamin D supplements did not have obvious impact on CD4 count and viral load. Likewise, vitamin D had no effect on time to sputum smear conversion, time to culture conversion, relapse, 12-month morality, and TB score.

RESUMO

BACKGROUND: Oral candidiasis is a common opportunistic infection in patients with human immunodeficiency virus (HIV). In addition, most of these patients suffer from vitamin D deficiency. This study aimed to investigate the association between vitamin D levels and oral candidiasis in patients with HIV infection. METHODS: This case‒control study was conducted on HIV-infected patients. Cases were patients with oral candidiasis diagnosed based on physical examinations. Controls were age- and sex-matched individuals without oral candidiasis. The levels of 25-OH vitamin D and other laboratory markers (CD4 count and viral load) were compared between the case and control groups. RESULTS: A total of 104 cases and 102 controls were included in the study. The cases had significantly lower 25-OH vitamin D3 levels (MD = 33.86 ng/mL, 95% CI= (31.85, 35.87), P < 0.001) and CD4 counts (MD = 267.48 cells/mm3, 95% CI= (189.55, 345.41), P < 0.001) than the controls. In addition, viral load was significantly higher in cases than in controls (MD = 7.03 × 105 copies/mL, 95% CI= (4.46 × 105, 9.61 × 105), P < 0.001). The multivariate logistic regression analysis revealed that educational status (OR = 0.032, 95% CI= (0.002, 0.100), P < 0.001), current HAART (OR = 0.005, 95% CI= (0.001, 0.014), P < 0.001), history of oral candidiasis (OR = 20.114, 95% CI= (18.135, 21.957), P < 0.001), CD4 count (OR = 0.004, 95% CI= (0.001, 0.006), P < 0.001), viral load (OR = 12.181, 95% CI= (1.108, 133.392), P < 0.001), and vitamin D level (OR = 0.011, 95% CI= (0.008, 0.015), P < 0.001) were significantly associated with the risk of developing oral candidiasis. CONCLUSIONS: Based on the findings, most patients with HIV infection suffer from vitamin D deficiency, especially those with oral candidiasis. Hypovitaminosis D was significantly associated with an increased risk of oral candidiasis. Thus, vitamin D supplementation may assist HIV-positive patients in improving their oral health and preventing oral candidiasis.

RESUMO

BACKGROUND: Public health problems related to tuberculosis (TB) remain substantial globally, particularly in resource-limited countries. Determining TB treatment outcomes and identifying contributing factors are the basic components of the TB control strategy. In Ethiopia, different studies have been done on treatment outcomes and multiple associated factors, and there is also a little information on the effect of nutritional status on TB treatment outcomes. So there is a need for comprehensive research that examines the combined effects of multiple factors along with nutritional status. METHODS: A five-year institution-based retrospective cross-sectional study was conducted at Mizan Tepi University Teaching Hospital, South West Ethiopia. This study included all tuberculosis patients who were documented in the TB registration and had known treatment outcomes at the treatment facility between January 1, 2016, and December 31, 2020. Data was collected through a pretested structured data extraction checklist. Data were entered into Epidata version 3.1 and analyzed through SPSS version 22. Multiple logistic regression was employed to assess the association between dependent and independent variables. A p-value of less than 0.05 was considered statistically significant. RESULT: Of the total 625 TB patients, 283 (45.3%), 175 (28%), and 167 (26.7%) had smear-positive, extra-pulmonary, and smear-negative tuberculosis, respectively. The majority of study participants had normal weight (62.2%), were in the age group of 15-44 (67.4%), were new cases (73.8%), and were from urban areas (69.4%). About 32.2% of cases were HIV-positive. The overall unsuccessful treatment rate was 25%. From the total unsuccessful treatment rates, the highest proportion was a death rate of 90 (14.4%), followed by a treatment failure of 56 (9%). Being female (AOR = 1.7, 95% CI: 1.2-2.5), HIV positive (AOR = 2.7, 95% CI: 1.9-4.1), undernutrition (BMI<18.5kg/m2) (AOR = 1.9, 95% CI: 1.3-2.9), and smear-negative pulmonary TB (AOR = 1.6, 95% CI: 1-2.5) were independent predictors of unsuccessful treatment outcomes. CONCLUSION: The treatment success rate in the study area is very poor. Poor treatment outcomes were associated with undernutrition, female gender, HIV positivity and smear-negative pulmonary TB. So, continuous and serious supervision and monitoring of directly observed treatment short course (DOTS) program accomplishment, early detection of HIV and TB, prompt anti TB and antiretroviral treatment initiation and adherence, enhanced nutritional assessment, and counseling services need to be strengthened to improve treatment outcomes.

RESUMO

BACKGROUND: cute kidney injury(AKI) is a rapid loss of the kidney's excretory function, resulting in an accumulation of end products of nitrogen metabolism. The causes of AKI in HIV-positive patients are not well investigated, but it may be associated with antiretroviral drug side effects and HIV itself. Even though there were studies that reported the prevalence of AKI among HIV-positive patients in Africa, their findings were inconsistent across the studies. METHODS: We searched on PubMed, Embas, Ebsco, OVID, Cochrane Library, and other supplementary search engines, including Google and Google Scholar. Articles published upto July 2023 were included in this review study. The quality of the study was assessed using the Newcastle-Ottawa Scale for cross-sectional, case-control, and cohort studies. The data were extracted using a Microsoft Excel spreadsheet and exported to Stata version 14 for analysis. A random effect meta-analysis model was used to estimate the pooled prevalence of AKI among HIV-positive patients. Heterogeneity was evaluated using Cochrane Q statistics and I squared (I2). Furthermore, the graphic asymmetric test of the funnel plot and/or Egger's tests were computed to detect publication bias. Sensitivity analysis was computed to see the effect of a single study on the summary effects. To treat the publication bias, a trim and fill analysis was carried out. The protocol of this review has been registered in an international database, the Prospective Register of Systematic Reviews (PROSPERO),with reference number CRD42023446078. RESULTS: A total of twenty-four original articles comprising 7913HIV-positive patients were included in the study. The pooled prevalence of AKI among HI-positive patients was found to be 23.35% (95% CI: 18.14-28.56%, I2 = 97.7%, p-value <0.001). Low hemoglobin (Hgb <8mg/dl) was found to be the determinant factor for AKI among HIV-positive patients (AOR = 2.4; 95% CI:1.69-3.4, I2 = 0.0%, p-value = 0.40). In meta-regression analysis, sample size was the possible source of variation among the included studies (AOR = 3.11, 95%CI: 2.399-3.83). CONCLUSIONS: The pooled prevalence of AKI among HIV-positive patients was high. HIV-positive patients with low hemoglobin levels are at risk of developing AKI. Hence, regular monitoring of kidney function tests is needed to prevent or delay the risk of AKI among HIV-positive patients. Healthcare workers should provide an integrated healthcare service to HIV-positive patients on the prevention, treatment, and reduction of the progression of AKI to advanced stages and complications.

RESUMO

BACKGROUND: Management of hypertension, dyslipidemia, diabetes and other modifiable factors may mitigate the cardiovascular disease (CVD) risk in people with human immunodeficiency virus (HIV, PWH) compared with people without HIV (PWoH). METHODS: This was a retrospective cohort study of 8285 PWH and 170 517 PWoH from an integrated health system. Risk factor control was measured using a novel disease management index (DMI) accounting for amount/duration above treatment goals (0% to 100% [perfect control]), including 2 DMIs for hypertension (diastolic and systolic blood pressure), 3 for dyslipidemia (low-density lipoprotein, total cholesterol, triglycerides), and 1 for diabetes (HbA1c). CVD risk by HIV status was evaluated overall and in subgroups defined by DMIs, smoking, alcohol use, and overweight/obesity in adjusted Cox proportional hazards models. RESULTS: PWH and PWoH had similar DMIs (80%-100%) except for triglycerides (worse for PWH) and HbA1c (better for PWH). In adjusted models, PWH had an elevated risk of CVD compared with PWoH (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.07-1.31). This association was attenuated in subgroups with controlled dyslipidemia and diabetes but remained elevated for PWH with controlled hypertension or higher total cholesterol. The strongest HIV status association with CVD was seen in the subgroup with frequent unhealthy alcohol use (HR, 2.13; 95% CI, 1.04-4.34). CONCLUSIONS: Control of dyslipidemia and diabetes, but not hypertension, attenuated the HIV status association with CVD. The strong association of HIV and CVD with frequent unhealthy alcohol use suggests enhanced screening and treatment of alcohol problems in PWH is warranted.

RESUMO

OBJECTIVE: Social determinants of health (SDH) are important determinants of long-term conditions and multimorbidity in the general population. The intersecting relationship between SDH and multimorbidity in people with HIV remains poorly studied. DESIGN: A cross-sectional study investigating the relationships between eight socio-economic parameters and prevalent comorbidities of clinical significance and multimorbidity in adults of African ancestry with HIV aged 18-65 years in South London, UK. METHODS: Multivariable logistic regression analysis was used to evaluate associations between SDH and comorbidities and multimorbidity. RESULTS: Between September 2020 and January 2022, 398 participants (median age 52 years, 55% women) were enrolled; 85% reported at least one SDH and 72% had at least one comorbidity. There were no associations between SDH and diabetes mellitus or kidney disease, few associations between SDH (job and food insecurity) and cardiovascular or lung disease, and multiple associations between SDH (financial, food, housing and job insecurity, low educational level, social isolation, and discrimination) and poor mental health or chronic pain. Associations between SDH and multimorbidity mirrored those for constituent comorbidities. CONCLUSION: We demonstrate strong associations between SDH and poor mental health, chronic pain and multimorbidity in people of black ethnicities living with HIV in the UK. These findings highlight the likely impact of enduring socioeconomic hardship in these communities and underlines the importance of holistic health and social care for people with HIV to address these adverse psychosocial conditions.

RESUMO

This review delves into the intricate relationship between anemia, iron metabolism, and human immunodeficiency virus (HIV), aiming to unravel the interconnected pathways that contribute to the complex interplay between these 3 entities. A systematic exploration of relevant literature was conducted, encompassing studies examining the association between anemia, iron status, and HIV infection. Both clinical and preclinical investigations were analyzed to elucidate the underlying mechanisms linking these components. Chronic inflammation, a hallmark of HIV infection, disrupts iron homeostasis, impacting erythropoiesis and contributing to anemia. Direct viral effects on bone marrow function further compound red blood cell deficiencies. Antiretroviral therapy, while essential for managing HIV, introduces potential complications, including medication-induced anemia. Dysregulation of iron levels in different tissues adds complexity to the intricate network of interactions. Effective management of anemia in HIV necessitates a multifaceted approach. Optimization of antiretroviral therapy, treatment of opportunistic infections, and targeted nutritional interventions, including iron supplementation, are integral components. However, challenges persist in understanding the specific molecular mechanisms governing these interconnected pathways. Decoding the interconnected pathways of anemia, iron metabolism, and HIV is imperative for enhancing the holistic care of individuals with HIV/AIDS. A nuanced understanding of these relationships will inform the development of more precise interventions, optimizing the management of anemia in this population. Future research endeavors should focus on elucidating the intricate molecular mechanisms, paving the way for innovative therapeutic strategies in the context of HIV-associated anemia.

RESUMO

OBJECTIVES: Heart failure risk is elevated in people with HIV (PWH). We investigated whether initial antiretroviral therapy (ART) regimens influenced heart failure risk. DESIGN: Cohort study. METHODS: PWH who initiated an ART regimen between 2000 and 2016 were identified from three integrated healthcare systems. We evaluated heart failure risk by protease inhibitor, nonnucleoside reverse transcriptase inhibitors (NNRTI), and integrase strand transfer inhibitor (INSTI)-based ART, and comparing two common nucleotide reverse transcriptase inhibitors: tenofovir disoproxil fumarate (tenofovir) and abacavir. Follow-up for each pairwise comparison varied (i.e. 7 years for protease inhibitor vs. NNRTI; 5 years for tenofovir vs. abacavir; 2 years for INSTIs vs. PIs or NNRTIs). Hazard ratios were from working logistic marginal structural models, fitted with inverse probability weighting to adjust for demographics, and traditional cardiovascular risk factors. RESULTS: Thirteen thousand six hundred and thirty-four PWH were included (88% men, median 40 years of age; 34% non-Hispanic white, 24% non-Hispanic black, and 24% Hispanic). The hazard ratio (95% CI) were: 2.5 (1.5-4.3) for protease inhibitor vs. NNRTI-based ART (reference); 0.5 (0.2-1.8) for protease inhibitor vs. INSTI-based ART (reference); 0.1 (0.1-0.8) for NNRTI vs. INSTI-based ART (reference); and 1.7 (0.5-5.7) for tenofovir vs. abacavir (reference). In more complex models of cumulative incidence that accounted for possible nonproportional hazards over time, the only remaining finding was evidence of a higher risk of heart failure for protease inhibitor compared with NNRTI-based regimens (1.8 vs. 0.8%; P  = 0.002). CONCLUSION: PWH initiating protease inhibitors may be at higher risk of heart failure compared with those initiating NNRTIs. Future studies with longer follow-up with INSTI-based and other specific ART are warranted.

RESUMO

Background: The Human Immunodeficiency Virus (HIV) epidemic is still a public health concern. Micronutrient deficiencies can fasten the progression of this syndrome. Selenium and zinc are essential trace elements, which exert antioxidant and anti-inflammatory activities in HIV infection. The present overview aimed to evaluate the current knowledge from systematic reviews (SRs) of the effects of selenium and zinc supplementation in HIV patients to show the most updated and comprehensive summary of previous SRs. Methods: The current study was performed according to the guidelines of the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) statements. To assess the quality of articles we used the Measurement Tool to Checklist Assess Systematic Reviews (AMSTAR). PubMed/Medline, Web of Science, Scopus, and EMBASE databases and Google Scholar web search engine were searched up until March 2022, using relevant keywords. Results: Among 3731 articles assessed, five and four studies met the inclusion criteria for selenium and zinc supplementation, respectively. Four studies found that selenium supplementation can be effective in delaying CD4 decline in HIV-infected patients. In four SRs, the dosage of selenium supplementation was 200 µg/day. Three studies, however, reported no significant effect of zinc supplementation on CD4 cell counts, and HIV viral load. The dosage of zinc supplementation ranged from 12 to 100 mg/day. The intervention duration ranged from 2 weeks to 18 months. Conclusion: In the present study, we identified some clinical evidence of a potential beneficial effect of selenium supplementation in HIV-infected patients.

RESUMO

OBJECTIVES: In 2018, the Botswana Tsepamo Study reported a nine-fold increased risk of neural tube defects in infants whose mothers were treated with dolutegravir (DTG) from the time of conception. As maternal folate supplementation and status is a well known modifier of neural tube defect (NTD) risk, we sought to evaluate birth outcomes in mice fed normal and low folic acid diets treated with DTG during pregnancy. DESIGN: DTG was evaluated for developmental toxicity using pregnant mice fed normal or low folic acid diet. METHODS: CD-1 mice were provided diet with normal (3 mg/kg) or low (0.3 mg/kg) folic acid. They were treated with water, a human therapeutic-equivalent dose, or supratherapeutic dose of DTG from mouse embryonic day E6.5 to E12.5. Pregnant dams were sacrificed at term (E18.5) and fetuses were inspected for gross, internal, and skeletal defects. RESULTS: Fetuses with exencephaly, an NTD, were present in both therapeutic human equivalent and supratherapeutic exposures in dams fed low folic acid diet. Cleft palates were also found under both folate conditions. CONCLUSIONS: Recommended dietary folic acid levels during mouse pregnancy ameliorate developmental defects that arise from DTG exposure. Since low folate status in mice exposed to DTG increases the risk for NTDs, it is possible that DTG exposures in people living with HIV with low folate status during pregnancy may explain, at least in part, the elevated NTD risk signal observed in Botswana. Based on these results, future studies should consider folate status as a modifier for DTG-associated NTD risk.

RESUMO

Substance use in people with HIV (PWH) negatively impacts antiretroviral therapy (ART) adherence. However, less is known about this in the current treatment era and the impact of specific substances or severity of substance use. We examined the associations of alcohol, marijuana, and illicit drug use (methamphetamine/crystal, cocaine/crack, illicit opioids/heroin) and their severity of use with adherence using multivariable linear regression in adult PWH in care between 2016 and 2020 at 8 sites across the US. PWH completed assessments of alcohol use severity (AUDIT-C), drug use severity (modified ASSIST), and ART adherence (visual analogue scale). Among 9400 PWH, 16% reported current hazardous alcohol use, 31% current marijuana use, and 15% current use of ≥1 illicit drugs. In multivariable analysis, current methamphetamine/crystal use, particularly common among men who had sex with men, was associated with 10.1% lower mean ART adherence (p < 0.001) and 2.6% lower adherence per 5-point higher severity of use (ASSIST score) (p < 0.001). Current and more severe use of alcohol, marijuana, and other illicit drugs were also associated with lower adherence in a dose-dependent manner. In the current HIV treatment era, individualized substance use treatment, especially for methamphetamine/crystal, and ART adherence should be prioritized.

RESUMO

BACKGROUND: Hyperthermia is a common monotherapy for sporotrichosis, but only in patients with special conditions, such as pregnancy and nursing. However, hyperthermia has not been used more widely for sporotrichosis in clinical practice. PATIENTS/METHODS: An HIV-positive adult male with lymphocutaneous sporotrichosis caused by Sporothrix globosa that did not respond to conventional itraconazole therapy lasting >2 months received adjunctive therapy with local hyperthermia. To simulate the effects of heat exposure on the growth and morphology of Sporothrix spp. in vitro, S. globosa, S. schenckii and S. brasiliensis were exposed to intermittent heat (42°C) for 1 h a day for 7 or 28 days and observed under transmission electron microscopy. RESULTS: Itraconazole combined with local hyperthermia significantly improved the lesions, and the patient was successfully cured of sporotrichosis, with no recurrence after 2 years of follow-up. Cultures of Sporothrix spp. treated with 7 days of daily heat exposure in vitro showed obvious decreases in colony diameters, but not numbers, compared with untreated cultures (p < .001). After 28 days of heat exposure in vitro, Sporothrix spp. were unable to thrive (p < .001), and ultrastructural alterations, including loose cell wall structure, incomplete cell membrane, disrupted vacuoles and fragmented nuclei, were noticeable. CONCLUSIONS: Our case findings and in vitro experiments on Sporothrix spp., together with a literature review of previous sporotrichosis cases, suggest that hyperthermia has a clinical role as a treatment adjunct. Large-scale clinical trials are required to examine the utility of hyperthermia in various forms of cutaneous sporotrichosis.

RESUMO

OBJECTIVES: People with HIV are an ageing population with an increased risk of cognitive impairment. Although cognitive impairment is dependent upon assessment, the acceptability of screening for cognitive impairment is unclear. This study aimed to explore the views of people with HIV and healthcare workers regarding routine screening for cognitive impairment. METHODS: In-depth individual qualitative interviews were conducted with purposively sampled people with HIV and focus groups of healthcare workers from a UK HIV service. Verbatim pseudonymized transcripts were analysed using reflexive thematic analysis supported by NVivo. RESULTS: Twenty people with HIV were interviewed and 12 healthcare workers participated in three focus groups. People with HIV were concerned about developing cognitive issues and were receptive to routine screening. Screening was seen as relevant and an important part of managing health in older age. Healthcare workers expressed concerns regarding the capacity of HIV services to implement routine screening and questioned the validity of screening measures used. People with HIV felt that screening and subsequent detection of cognitive impairment, if present, may help them to prepare for future issues and promote active management strategies and care pathways that would support cognitive health. People with HIV felt that screening should be brief and delivered by the HIV service and that they should be given a choice of administration method. Indications of cognitive impairment detected by a brief screening assessment should be discussed face to face and followed up with a comprehensive assessment. CONCLUSIONS: People with HIV are concerned about cognitive impairment and would welcome regular screening for this as part of the holistic care provided by the HIV team. Both people with HIV and healthcare workers would like more information on cognitive impairment, its screening and ways to support cognitive health.

RESUMO

OBJECTIVE: Justice involvement and psychiatric comorbidities contribute to excess HIV morbidity, yet their interaction is poorly understood. We examined associations of this overlap with HIV outcomes among people living with HIV (PLWH). METHODS: We conducted a retrospective cohort study of PLWH aged 13 years and older residing in Marion County (Indianapolis), IN, during 2018 (n = 5730) using linked HIV surveillance, arrest, and clinical data. We used univariable and multivariable regression to evaluate main and interaction effects of 2010-2017 arrest and mental health diagnosis on 2018 linkage to care (LTC), retention in care (RIC), and undetectable viral load (UVL). RESULTS: LTC decreased among those with, versus without, an arrest (P = 0.02), although mental health diagnoses had no significant effect on LTC. When controlling for demographics and substance use disorder, analyses indicated a protective effect of arrest history on odds of RIC (adjusted odds ratio [aOR] = 1.54) and UVL (aOR = 1.26). Mental health diagnosis also increased odds of RIC (aOR = 2.02) and UVL (aOR = 1.95). Post hoc tests demonstrated that these results were mediated by outpatient care utilization, although an arrest or mental health diagnosis did increase odds of RIC among PLWH and a history of low outpatient utilization. CONCLUSIONS: Outpatient care utilization improves HIV outcomes, even among those with justice involvement and psychiatric comorbidities. Holistic approaches to care can increase utilization. Implementation of "no wrong door" approaches, such as integration of mental health care in the primary care setting, simplifies health care navigation and improves access. Among those arrested, access to a Behavioral Court program can improve, rather than disrupt, HIV care.

RESUMO

INTRODUCTION: Several HIV-related syndemics have been described among adults. We investigated syndemic vulnerability to hazardous drinking (HD), intimate partner violence (IPV) and household food insecurity (HFIS) in breastfed children born without HIV in urban South Africa. We compared those who were perinatally HIV exposed (CHEU) to those who were not (CHU), under conditions of universal maternal antiretroviral therapy (ART) and breastfeeding. METHODS: A prospective cohort of pregnant women living with HIV (WLHIV), and without HIV, were enrolled and followed with their infants for 12 months postpartum (2013-2017). All WLHIV initiated antenatal efavirenz-based ART. Measurements of growth (∼3 monthly), infectious cause hospitalisation, ambulatory childhood illness (2-week recall) and neurodevelopment (BSID-III, measured at ∼12 months' age) were compared across bio-social strata using generalised linear regression models, with interaction terms; maternal data included interview-based measures for HD (AUDIT-C), IPV (WHO VAW) and HFIS. RESULTS: Among 872 breastfeeding mother-infant pairs (n = 461 CHEU, n = 411 CHU), WLHIV (vs. HIV negative) reported more unemployment (279/461, 60% vs. 217/411, 53%; p = 0.02), incomplete secondary education (347/461, 75% vs. 227/411, 55%; p < 0.0001), HD (25%, 117/459 vs. 7%, 30/411; p < 0.0001) and IPV (22%, 101/457 vs. 8%, 32/411; p < 0.0001) at enrolment; and HFIS at 12 months (45%, 172/386 vs. 30%, 105/352; p > 0.0001). There were positive interactions between maternal HIV and other characteristics. Compared to food secure CHU, the mean difference (95% CI) in weight-for-age Z-score (WAZ) was 0.06 (-0.14; 0.25) for food insecure CHU; -0.26 (-0.42; -0.10) for food secure CHEU; and -0.43 (-0.61; -0.25), for food insecure CHEU. Results were similar for underweight (WAZ < -2), infectious-cause hospitalisation, cognitive and motor delay. HIV-IPV interactions were evident for ambulatory diarrhoea and motor delay. There were HIV-HD interactions for odds of underweight, stunting, cognitive and motor delay. Compared to HD-unexposed CHU, the odds ratios (95% CI) of underweight were 2.31 (1.11; 4.82) for HD-exposed CHU; 3.57 (0.84; 15.13) for HD-unexposed CHEU and 6.01 (2.22; 16.22) for HD-exposed CHEU. CONCLUSIONS: These data suggest that maternal HIV-related syndemics may partly drive excess CHEU health risks, highlighting an urgent need for holistic maternal and family care and support alongside ART to optimise the health of CHEU.

RESUMO

BACKGROUND: There is a limited understanding about the impact of spiritual beliefs and activities on HIV seroconversion among black men who have sex with men (BMSM), which we investigate in this study. SETTING: United States. METHODS: The HIV Prevention Trials Network Study 061 collected demographic and biomedical assessments among BMSM across 6 United States cities for longitudinal analysis. Spiritual beliefs and spiritual activities are constructed composite scales. Bivariate analyses among 894 who provided data at 12-month follow-up compared men who seroconverted to HIV between baseline and 6 months with those who remained uninfected with HIV at 12 months. Cox proportional hazard regression among 944 men tested spiritual beliefs and activities on the longitudinal risk of HIV seroconversion adjusting for age and any sexually transmitted infection (STI). RESULTS: Among this sample, HIV incidence between baseline and 6 months was 1.69%, (95% confidence intervals [CI]: 1.04 to 2.77). Men who seroconverted to HIV were significantly younger than those who remained uninfected at the 12-month follow-up: (mean age 27, SD = 11 vs 37, SD = 12) and a higher proportion reported any STI (46.67% vs 11.39%, P < 0.01). A one-unit increase in spiritual beliefs was associated with lower hazard rate of seroconverting to HIV at follow-up [adjusted hazard ratio (aHR) = 0.37, 95% CI: = (0.16 to 0.87)]. Religious service attendance and spiritual activities were unrelated to seroconverting. CONCLUSIONS: Spirituality is important in the lives of BMSM. Biomedical and behavioral HIV prevention interventions should consider assessing spiritual beliefs in HIV care among BMSM.
