RESUMO

OBJECTIVES: To explore the health impacts of Hurricane Maria (HM) on HIV care outcomes among people living with HIV who use drugs. METHODS: Using data from an ongoing cohort study in San Juan, Puerto Rico (Proyecto PACTo), we measured differences in HIV care outcomes (viral load, viral suppression, and CD4 counts) before and after HM using assessments conducted at 6-month intervals. Generalized estimating equations were used to assess factors associated with HIV care outcomes. RESULTS: All HIV care outcomes showed a deterioration from pre-HM values to post-HM values (mean viral load increased, CD4 counts decreased, and rate of viral suppression decreased) after controlling for pre-HM sociodemographic and health characteristics. In addition to HM, age (aIRR = 1·01), being homeless (aIRR = 0·78) and having health insurance (aIRR = 1·6) were independently associated with viral suppression. PARTICIPANTS: 219 participants completed follow-up visits between April 2017 and January 2018, before and after HM. CONCLUSIONS: People living with HIV who use drugs in Puerto Rico experienced poorer HIV outcomes following HM. Socio-environmental factors contributing to these outcomes is discussed in the context of disaster response, recovery, and program planning.

RESUMO

Patients with immune conditions and immune-modifying therapies were excluded from the Covid-19 vaccine trials. Studies have shown conflicting response to different vaccines in persons receiving immune suppressors or biologics. The aim of this study is to evaluate humoral and cellular response to Covid-19 vaccines in patients with Inflammatory Bowel Disease (IBD) using biologic and/or immunomodulatory (IMM) therapies. Methods: Participants are adults with IBD receiving biologics or IMM planning to receive a Covid 19 vaccine. Cellular immunity (CD4+ and CD8+ T cell levels) with flow cytometry are measured at baseline and 2 weeks after each vaccine dose. Humoral immunity (antibody titers and neutralizing capacity,VNT%) is analyzed by ELISA at baseline, 2 weeks after each dose, and 6 and 12 months after vaccine. We present the early results of the first 19 subjects. The study is approved by the IRB. Results: 19 subjects (18 in biologics and 1 in IMM) who received 2 doses of the Pfizer-BioNTech vaccine are included. Total IgG antibodies increased 21.13 times after the first dose and 90 times after the second dose. VTN% increased 11.92 times after the first dose and 53.79 times after the second dose. When compared with a healthy control cohort, total IgG antibodies and VTN% were lower in the subjects after the first dose. After the second dose, IgG antibodies increased but remained lower than controls, but VTN% were similar to controls. CD4 and CD8 mean levels had an upward trend after vaccination. Conclusions: Neutralizing capacity response to the vaccine in subjects was similar to a healthy cohort in spite of lower increases in total IgG antibodies. The CD4 and CD8 results observed may support the capacity to mount an effective cellular response in patients on biologics. Larger studies are needed to determine vaccine efficacy in these patients.

RESUMO

Alliances between the government and academic communities can be a key component of the public health response to an emergency such as the coronavirus disease 2019 (COVID-19) pandemic. The Governor of Puerto Rico designated the Puerto Rico Medical Task Force (MTF) COVID-19 to provide direct guidance and evaluation of the government response to the epidemic in Puerto Rico. Several work groups were formed within the MTF to create protocols and provide evidence-based recommendations on different public health aspects. The collaboration between the academia and the government enhanced the Puerto Rican public health response and contributed to the reduction seen in the contagion curve. Healthcare services and hospitals have not reached their maximum patient care capacity and the death toll has been controlled. Incorporating a national MTF with members of the academia into the government structure was beneficial during the COVID-19 response in Puerto Rico. A similar strategy could serve as a model for other states or territories and countries in similar scenarios.

RESUMO

BACKGROUND: Low cardiorespiratory fitness (CRF) is usually observed in people living with HIV. The effect of a low-volume high-intensity interval training (LV-HIIT) on CRF in HIV+ and HIV- Hispanic women was evaluated in this study. SETTING: A nonrandomized clinical trial with pre-test and post-test using a LV-HIIT intervention was conducted in the AIDS Clinical Trials Unit and the Puerto Rico Clinical and Translational Research Consortium at the University of Puerto Rico Medical Sciences Campus. METHODS: Twenty-nine HIV+ and 13 HIV- Hispanic women recruited from community-based programs and clinics, and able to engage in daily physical activities, volunteered to participate. Of these, 20 HIV+ (69%) and 11 HIV- (85%) completed the study and were included in the analyses. LV-HIIT consisted of 6-week, 3 d/wk, 8-10 high-intensity and low-intensity intervals on a cycle ergometer at 80%-90% of heart rate reserve. Main outcome measures were CRF (defined as VO2peak), peak workload, and time to peak exercise. RESULTS: Average peak workload and time to peak exercise increased after training (P < 0.05) in both groups. However, average CRF was significantly higher after training only in the HIV- group. Gains in CRF were observed in 100% of HIV- and 50% of HIV+ women. This was not influenced by exercise testing, habitual physical activity, or anthropometric variables. CONCLUSIONS: Given the lack of change in CRF observed in the HIV+ group after LV-HIIT intervention, it is important to focus on variations that may occur within groups.

RESUMO

BACKGROUND: Puerto Rico is among the areas with the highest estimated rates of people living with HIV in the United States. Despite the epidemiologic data available, there is limited real-world information that can help understand the comorbidities of people with HIV. In this study, we describe common comorbidities among adults with HIV attending treatment clinics in Puerto Rico. METHODS: An exploratory, retrospective, cross-sectional study was conducted at five HIV clinics in Puerto Rico. A random sample of medical records was reviewed. Descriptive statistics were used to summarize patient demographics, morbidity, and clinical characteristics. Multivariate analyses were conducted to explore comorbidities by age and sex. RESULTS: A total of 250 (179 men; 71 women) medical records were reviewed. Participants' mean age was 47.9 years and on average they had been living with HIV for 9 years. Most (97.6%) had at least one comorbidity. The most common comorbidities were dyslipidemia and hypertension. Men were more likely to have been diagnosed with alcohol misuse while women were more likely to have been diagnosed with obesity, human papillomavirus (HPV), hypothyroidism, and osteoporosis. Participants younger than 50 years of age were more likely to have history of alcohol misuse while older individuals (50 years and old) were more likely to have been diagnosed with dyslipidemia, hypertension, and diabetes. Adjusting by sex and age, women were more likely to have been diagnosed with obesity and depression and those older than 50 years were more likely to have had a diagnosis of dyslipidemia, hypertension, HPV, and diabetes. CONCLUSIONS: This is one of the few studies assessing comorbidities among adults with HIV in Puerto Rico, among Latino/Hispanics within the United States, and Latin America. Consistent with other studies, cardiovascular diseases are common among adults with HIV in Puerto Rico. Findings support the need for awareness and real-world evidence about comorbidities among people with HIV when implementing screenings and prescribing drugs.

RESUMO

BACKGROUND: Substance use, particularly injection drug use, continues to fuel the HIV/HCV (hepatitis C virus) epidemics in San Juan, Puerto Rico (PR). AIM: This article examines individual and sociostructural factors that affect HIV/HCV risk among people who use drugs (PWUD) living with or at risk for HIV/HCV in San Juan, PR. Findings were used to inform a community-level intervention to enhance HIV care access and retention for this population. METHOD: A rapid ethnographic assessment in collaboration with a community-based organization was conducted. Data collection took place between June and December 2013 and included field observations, 49 unstructured interviews with PWUD, and 19 key informant interviews with community stakeholders. Fieldnotes, photographs, and interview transcripts were analyzed for recurrent themes and to address the intervention-planning needs. Study results are presented as fieldnote excerpts, direct quotes from interviews, and photographs. RESULTS: Findings suggest that PWUD in PR face myriad challenges that affect HIV/HCV risk and hinder linkage to and retention in care. Results describe a layered risk environment where PWUD encounter many barriers to prevention, care, and treatment such as transience, social isolation, stigma, limited housing options, and inadequate medical and substance use disorder treatment services. DISCUSSION: These observed circumstances provide an empirical basis for the development and evaluation of comprehensive interventions that may serve to reduce barriers to care and link individuals to other supportive services. CONCLUSION: New approaches and comprehensive interventions are needed to break the structures that perpetuate risk and lack of engagement and retention in HIV care and substance use disorder treatment in San Juan.

RESUMO

BACKGROUND: HIV prevalence in Puerto Rico is nearly twice that of the mainland United States, a level that was substantially fueled by injection drug use. Puerto Rico has a longstanding history of health provision by the public sector that directly affects how HIV and substance use disorder (SUD) treatment services are provided and funded. As part of pre-implementation research for a randomized trial of a community-level intervention to enhance HIV care access for substance users in San Juan, Puerto Rico, we sought to understand the structural and health policy environment for providing HIV and SUD treatments. METHODS: We conducted semi-structured qualitative interviews (n = 8) with government and program administrators in English and Spanish. Data were analyzed to identify dominant and recurrent themes. RESULTS: Participants discussed how lack of integration among medical and mental health service providers, lack of public transportation, and turnover in appointed government officials were barriers to integrated HIV and SUD treatment. Federal funding for support services for HIV patients was a facilitator. The Affordable Care Act has limited impact in Puerto Rico because provisions related to health insurance reform do not apply to U.S. territories. DISCUSSION AND CONCLUSIONS: Implications for intervention design include the need to provide care coordination for services from multiple providers, who are often physically separated and working in different reimbursement systems, and the potential for mobile and patient transportation services to bridge these gaps. Continuous interaction with political leaders is needed to maintain current facilitators. These findings are relevant as the current economic crisis in Puerto Rico affects funding, and may be relevant for other settings with substance use-driven epidemics.

RESUMO

OBJECTIVE: Hispanics in Puerto Rico (PR) have a high prevalence of metabolic syndrome (met-syn), partially explained by low physical activity (PA) and possibly low cardiorespiratory fitness (VO2peak). Met-syn is also associated with lipodystrophy in HIV infected (HIV+) adults taking antiretroviral therapies. However, associations between met-syn, VO2peak, PA, sedentary behavior and lipodystrophy among HIV+ Hispanics have not been adequately reported. We tested the following hypotheses: 1) HIV+ Hispanics with lipodystrophy (HIV-Lipo) would have a higher prevalence of met-syn, lower VO2peak and PA, and higher sedentary behavior compared with those without lipodystrophy (HIV-no-Lipo) and without HIV infection (Non-HIV); and 2) met-syn would be inversely associated with VO2peak and PA, and directly associated with sedentary behavior. METHODS: Ninety Hispanic adults (32 HIV-Lipo, 28 HIV-no-Lipo, 30 Non-HIV) completed measurements of VO2,peak, anthropometry, PA and sedentary behavior with accelerometry, blood pressure, fasting glucose, insulin, and lipids. ANOVA and chi-square tests were used to detect differences between groups, and regression analyses to test associations between variables. RESULTS: More HIV-Lipo (69%) had met-syn compared with HIV-no-Lipo (39%) and Non-HIV (37%) (P = 0.002). Sedentary behavior and PA were not different, but VO2peak differed between all groups: lowest in HIV-Lipo and highest in non-HIV. PA and sedentary behavior were not associated with met-syn, but PA was directly associated with VO2peak (R2 = 0.26, p < 0.01). Also, a lower odds ratio for met-syn was observed with higher VO2peak (0.87; 95% CI: 0.83-0.95). CONCLUSION: Met-syn is related to lipodystrophy in HIV+ Hispanics in PR, and high VO2peak may protect against met-syn in this population.

RESUMO

OBJECTIVE: Human immunodeficiency virus (HIV) infection and antiretroviral treatment are associated with metabolic and cardiovascular complications that resemble metabolic syndrome (MetS) and potentially increase the risk of diabetes and cardiovascular disease in this population. The purpose of this study was to determine the prevalence of MetS and its individual components among Hispanics living with HIV in Puerto Rico. METHODS: Data from 909 clinical records were extracted and the prevalence of MetS determined using the NCEP-ATPIII criteria. Fisher's exact test was used to detect sex differences, and logistic regression to examine the effect of age, sex, smoking, years of HIV infection, antiretroviral therapy, and Hepatitis C coinfection. RESULTS: The prevalence of MetS in our study group (35.4%) was higher than previously reported in the United States, but not higher than in the general population in Puerto Rico. Females had a higher prevalence of MetS (44.2%) than males (30.5%); mostly explained by high body mass index and waist circumference. Age and sex were associated with the presence of MetS. CONCLUSION: Understanding ethnic and sex differences in the prevalence of metabolic risk factors is essential for the implementation of specific targeted interventions to prevent subsequent vascular morbidity and mortality in this population.

RESUMO

Hispanics represent 13% of the U.S. population but account for 19% of the new AIDS cases reported in 2000. The antiretroviral drug therapy used for the treatment of HIV/AIDS may cause lipodystrophy and insulin resistance, among other effects. Physical and leisure activities reduce these effects and improve the emotional and physical well-being of HIV-positive persons. This study describes physical and leisure activities, life satisfaction, depression, and body composition of HIV-positive Hispanics in Puerto Rico and compares body composition, CD4 counts, depression, leisure time, and life satisfaction of participants classified as physically active or inactive. Sixty-eight individuals were evaluated using questionnaires and biophysical measurements. Descriptive statistics and independent t tests were used for data analysis. Physically active participants had higher life satisfaction scores and healthier body composition as compared to those physically inactive. Health professionals must encourage the promotion of a physically active lifestyle among HIV-positive Hispanics.
