Abstract
Background Studies which examine quality of life (QOL) provide important insights that are needed to understand the impacts of HIV/AIDS anti-retroviral treatment (ART), comorbid conditions and other factors on the daily activities of people living with HIV/AIDS (PLH). This study aimed to determine the inter-relationships between clinical factors, behavioural, socio-demographic variables and QOL among PLH. Methods The secondary analysis used data collected from 293 people living with HIV/AIDS (PLH) receiving second-line ART in Johannesburg in a clinical trial which evaluated the non-inferiority of ritonavir-boosted darunavir (DRV/r 400/100 mg) compared to ritonavir-boosted lopinavir (LPV/r) over a 48 week-period. Physical functioning, cognitive and mental QOL were measured using the Aids Clinical Trial Group questionnaire. Exploratory factor analyses were used to examine the structure, the relationships between and the construct validity of QOL items. Structural equation models which tested the a priori-hypothesised inter-relationships between QOL and other variables were estimated and goodness of fit of the models to the data was assessed. Results Patients on darunavir presented with lower pill burden. Older patients and women were more likely to report lower QOL scores. Pill burden mediated the effects of age, sex and treatment regimen on physical functioning QOL and adverse effects; the effects of age, sex, treatment regimen and adverse effects on cognitive QOL; and the effects of sex on mental QOL. Conclusion QOL among PLH is associated with socio-demographic and clinical factors. Therefore, QOL could be enhanced by considering PLH characteristics, clinical factors such as regimen side-effects profile, management of comorbid conditions and mitigating risks such as potential adverse drug-to-drug interactions among patients on ART.

Tancredi MV, Sakabe S, Waldman EA. Mortality and survival of tuberculosis coinfected patients living with AIDS in São Paulo, Brazil: a 12-year cohort study. BMC Infect Dis 2022; 22:223. [PMID: 35246066 PMCID: PMC8897065 DOI: 10.1186/s12879-022-07232-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Accepted: 02/28/2022] [Indexed: 11/17/2022] Open
Abstract
Background TB is still one of the leading causes of death among HIV patients. This study evaluates the effect of TB on the mortality rate, survival time, and predictors of survival in patients with AIDS living in different areas in São Paulo State (SPS). Methods Retrospective cohort of adolescents and adults with AIDS, diagnosed between 2003 and 2007 and followed-up until 2014. Data were obtained from the Brazilian Ministry of Health. Mortality rates were estimated by person-years. Survival analysis used the date of diagnosis as the reference for the construction of Kaplan–Meier curves. The Cox model was used for the investigation of survival-associated factors. Results A total of 35,515 patients were included, of whom 63.0% were male; 64.7% at the age group of 30 to 49 years, 64.4% were white, 12.9% co-infected with TB, and 37.6% had CD4 count above 200 cells/mm3 at diagnosis of AIDS. The 12-year survival probabilities were 74.1% and 55.7% among patients without and with TB co-infection, respectively. After adjustment for sex, age and year of diagnosis, the following exposures were independently associated with lower survival: residing in municipalities of the Interior (Hazard ratio (HR) = 1.43) and Coastal Area (HR = 1.9); illiteracy (HR = 2.61); being co-infected with TB (HR = 1.70); CD4 count below 200 cells/mm3 at AIDS diagnosis (HR = 2.31); viral load above 500 copies/ml at AIDS diagnosis (HR = 1.99); HAART1 regimen (one non-nucleoside reverse transcriptase inhibitor or boosted old protease inhibitors) (HR = 1.94). Conclusion The impact of TB on survival of AIDS was heterogeneous, and affected by age, years of formal education, early AIDS diagnosis, and proper ARV treatment. These factors may not fully explain the different survival outcomes in each of the four regions within the same state. These results may subsidize focused interventions and public health policies conveying specific needs in each of the areas.

Abstract
OBJECTIVE We aimed to investigate the prevalence of depressive symptoms among people living with HIV (PLHIV) on antiretroviral therapy (ART) in a large HIV treatment facility in Jakarta, Indonesia, and to assess associated factors. METHODS The Indonesian version of Beck Depression Inventory-II was used to assess depressive symptoms of 346 participants visiting the HIV Integrated Clinic Cipto Mangunkusumo hospital between June and November 2018. RESULTS Depressive symptoms (BDI-II score ≥14) were exhibited by 50.9% of participants, with prevalences of mild, moderate and severe depression of 30.4%, 15.6% and 4.9%, respectively. Poisson regression with robust variance analysis indicated that having lower income (aPR = 1.38, 95% CI 1.12-1.63), duration of ART for 1-5 years (aPR = 1.25, 95% CI 1.01-1.54) and same-sex partnership (aPR = 1.27, 95% CI 1.02-1.58) were positively associated with depressive symptoms. Age, sex and history of using intravenous drugs, and ART-based regimen were not associated with depressive symptoms. CONCLUSIONS Depressive symptoms were common among our population despite long-term ART use and were associated with having low-income, ART for 1-5 years and same-sex partnership.

Abstract
BACKGROUND There is evidence that Quality of Life (QoL) of People Living with HIV/AIDS (PLHIV) has a significant role in ART retention, treatment adherence, and survival. As a result, QoL is becoming increasingly important for policymakers, program implementers, and researchers. However, factors associated with QoL, in a culturally diverse country like Cameroon are unknown. OBJECTIVE We aimed to assess the QoL of PLHIV on ART and assess the extent to which physical, psychosocial, environmental, and spiritual factors drive QoL. METHOD A cross-sectional study was conducted among 394 PLHIV aged >21 in North-West Cameroon from April to July 2019. Data were collected using WHO-QOL BREF questionnaire. Descriptive statistics, bivariate, and multivariate linear regression analyses were performed. RESULTS Majority (34.5%) of participants were in the age range of 41-50, with 73% females. The average QoL of the respondents was "good" with mean score of 3.57 on 5 and 71.4% agreed to have satisfactory QoL. Bivariate regression analyses revealed that all six proposed predictors were significantly associated with QoL. Psychological factors made the greatest impact (β = 0.213; p<0.003), followed by physical factors (β = 0.19; p<0.001). CONCLUSION PLHIV fairly agreed to have good QoL. The QoL was driven by mainly psychological and physical factors and not level of independence. However, the mean score perceptions for the investigated domains were low. Mental health services should consider these predictors when designing strategies to improve the QoL of PLHIV. While this study provides useful insights, other possible drivers of QoL among PLHIV should be investigated.

Abstract
OBJECTIVE To evaluate the effect of the distance between the place of residence and the specialized treatment service on the survival time of people living with HIV/Aids in Alagoas, Northeast Brazil. METHODS Data from the notification and mortality systems related to individuals aged 13 years or older diagnosed with the infection between 2007 and 2013 were used. The cases were observed for a period of follow-up until December 2017. For the analyses, the Pearson's χ2 test, Kaplan-Meier method, and Cox regression were adopted according to the outcome of the case, place of residence, distance to the health unit, population size of the municipality of residence, sex, skin color/ethnicity, and age. RESULTS Of the 2,732 analyzed cases, 760 individuals died of Aids-related causes. The average estimate of survival time for individuals residing in the capital was 98.6 months (95%CI 96.1-101). Among residents of inland cities, the estimate was 92.7 months (95%CI 89.3-96.1). There was a significant difference in curves throughout the period. The group residing in inland municipalities and those traveling a distance of >70 km had a higher average relative risk of death (RR=1.21, 95%CI 1.05-1.4 and RR=1.18, 95%CI 1.01-1.39, respectively). CONCLUSION Living in or near the capital decreases the average relative risk of death. In order to increase the survival time of HIV/Aids patients in Alagoas, it is suggested to decentralize specialized health care, that is, to create regional centers to care for these people.

Abstract
INTRODUCTION The trend toward stabilization regarding the AIDS epidemic in Brazil over the past decade hides a very complex scenario, where two-thirds of the Brazilian federative units exhibit AIDS standardized mortality rates (ASMR) significantly above the national average and/or in upward tendency. ASMR in Rio de Janeiro State remains virtually unchanged over the years; the state currently occupies the second position in the national ranking of this indicator. OBJECTIVE To assess temporal trends in causes of death searching for differential profiles that could be useful for understanding mortality among patients with HIV in the state. METHODOLOGY Causes of death were analyzed in any field of the death certificates from the Mortality Information System between 1999 and 2015 for individuals ≥ 15 years of age. Cardiovascular diseases, non-AIDS-related cancers, external causes, diabetes mellitus, and tuberculosis were established by the mention or not of their codes according to the 10th edition of International Statistical Classification of Diseases and Related Health Problems (ICD-10) in death certificates. Generalized linear mixed-effects models were used to describe odds ratios in relation to 1999 and adjusted mean annual variations. RESULTS The results point to the emerging role of external causes and genitourinary diseases and the persistent role played by tuberculosis, differentially affecting AIDS mortality in the state, in a scenario of high mortality due to infectious diseases. CONCLUSION These data suggest that tuberculosis remains a major cause of death among people living with HIV/AIDS (PLWHA) in Rio de Janeiro, highlighting the need for studies that identify individual-level factors impacting their survival, thus improving local HIV/AIDS control measures.

Abstract
Ensuring the wellbeing of people living with HIV (PLWH) has become a significant public health concern in the era of highly active antiretroviral therapy. This study was to assess the quality of life (QoL) among PLWH in South Carolina (SC) and to examine the relationship between self-reported viral load (VL) suppression and their perceived QoL. In 2018, a cross-sectional survey was conducted among 402 PLWH from a large immunology clinic in SC. The WHOQoL brief version (WHOQoL-HIV-BREF) instrument with six domains (physical health, psychological health, social relations, independence, environmental health, and spirituality) and two specific questions (overall rate of QoL and satisfaction with health) were used. On a five-point scale, the participants rated their overall rating of QoL as good (mean = 4.07). The participants reported their psychological health as the highest (mean = 3.88) followed by environmental health (mean = 3.82), social relations (mean = 3.69), and independence (mean = 3.47). 71% reported an undetected VL. In multivariable analyses, self-awareness of undetected VL was significantly associated with satisfaction with health, psychological health, social relations, environmental health, but negatively associated with spirituality. These findings suggest that self-awareness of undetected VL had a significant impact on their perceived QoL beyond sociodemographic factors among PLWH who were linked to care in SC.

Abstract
Background The aim of this study was to establish the prevalence of lipodystrophy and its association to cumulative exposure to antiretroviral drugs. Method We conducted a cross sectional study in all HIV- infected patients attending the HIV clinic in the Centre hospitalier universitaire de Montréal (CHUM) with DEXA scan. Lipodystrophy was defined as a trunk/limb fat ratio ≥ 1.5. Association between cumulative exposure to antiretroviral (measured in years of use) with trunk/limb fat ratio (coded as a continuous variable) was assessed using univariate and multivariate linear regression for each antiretroviral drug with at least 40 exposed patients. Results One hundred sixty-six patients were included. Seventy-five percent were male, median age was 56 years, 67% were Caucasian. Overall, prevalence of lipodystrophy was 47%, with a mean trunk/limb fat ratio of 1.87, SD = 1.03, min = 0.6 and max = 5.87. Each 10-year increase in age and HIV infection duration was associated with an average increase of 0.24 and 0.34 for the trunk/limb fat ratio respectively. (p = 0.003, p = 0.002, respectively) Patients classified as lipodystrophic were more likely to be diabetic (50 vs. 28%, p = 0.07) and to have dyslipidemia (47 vs. 19%, p = 0.01). According to viral load at DEXA test, each one log increase was associated with less probability (0.7) of lipodystrophy. (p = 0.01) Among ARV drugs tested, there was an association between years of use of d4T, ritonavir and raltegravir and higher trunk/limb fat ratio (indicating more lipodystrophy) (p < 0.05). Conclusion Lipodystrophy is very common in HIV infected patients and is correlated with duration of some new antiretroviral drugs.

Abstract
This study investigated the underreporting of deaths due to Acquired Immunodeficiency Syndrome (AIDS) in Brazil, using the product of the linkage between the Mortality Information System (SIM) and the Hospital Information System (SIH) for the years 2008 to 2012. The hypothesis was that there were deaths recorded in the SIM that should have AIDS as the underlying cause of death, but that had been poorly classified. Many of the decedents had previous hospitalizations due to the illness. Underreported AIDS deaths were defined taking into account the coding rules of the International Classification of Diseases 10th Revision, in order to discriminate AIDS deaths from those due to other causes in people living with HIV / AIDS. In this period, 60,362 deceased had AIDS as the underlying cause, and we found another 2,671 (4.2%) as underreported causes. Underreported deaths increased the average AIDS mortality rate from 6.3/100,000 to 6.6/100,000. In conclusion, this study demonstrated that, through linkage in between SIH and SIM, it is possible to find underreporting of AIDS deaths in Brazil. These results serve as a warning for the need for actions that would promote a better certification of the causes of death among AIDS patients.

Abstract
Emerging evidence suggests that HIV incidence rates in Brazil, particularly among men, may be rising. Here we use Brazil's integrated health systems data to develop a mathematical model, reproducing the complex surveillance systems and providing estimates of HIV incidence, number of people living with HIV (PLHIV), reporting rates and ART initiation rates. An age-structured deterministic model with a flexible spline was used to describe the natural history of HIV along with reporting and treatment rates. Individual-level surveillance data for 1,077,295 cases (HIV/AIDS diagnoses, ART dispensations, CD4 counts and HIV/AIDS-related deaths) were used to calibrate the model using Bayesian inference. The results showed a second wave of infections occurring after 2001 and 56,000 (95% Credible Interval 43,000-71,000) new infections in 2015, 37,000 (95% CrI 28,000-54,000) infections in men and 16,000 (95% CrI 10,000-23,000) in women. The estimated number of PLHIV by end-2015 was 838,000 (95% CrI 675,000-1,083,000), with 80% (95% CrI 62-98%) of those individuals reported to the Ministry of Health. Women were more likely to be diagnosed and reported than men; 86.8% of infected women had been reported compared with 75.7% of men. Likewise, ART initiation rates for women were higher than those for men. The second wave contradicts previous estimates of HIV incidence trends in Brazil and there were persistent differences in the rates of accessing care between men and women. Nevertheless, the Brazilian HIV program has achieved high rates of detection and treatment, making considerable progress over the past ten years.

Abstract
OBJECTIVES To describe the changes in body fat distribution (BFD) occurring over 60 months in a group of antiretroviral therapy (ART)-naive individuals starting different antiretroviral regimens. METHODS A prospective ongoing fat change assessment including clinical evaluation and dual X-ray absorptiometry scan is being conducted in all consecutive patients initiating ART from January 2008. Arm, leg, trunk, and total fat as well as fat mass ratio were determined. RESULTS A total of 146 patients were included (80% male, 40% MSM). Mean age was 44 years, HIV-1 RNA was 4.98 log10 copies/mL, and CD4 count was 254 cells/μL. The most common initial antiretroviral combination included non-nucleoside reverse transcription inhibitor (NNRTI) drugs followed by protease inhibitor (PI) and integrase strand transfer inhibitor (INSTI)-based regimens. At month 36, an increase was seen in the body mass index (BMI), total fat, trunk fat, and limb fat. The fat mass ratio (FMR) also showed a significant increase in both men and women (P = 0.001). In patients receiving NNRTI- or INSTI-based regimens (but not PIs), there was a marginal but statistically significant increase in the FMR (0.10 and 0.07, respectively; P = 0.01). Sixty-two subjects completed 60 months of follow-up. FMR showed a significant increase even in the PI group at this time point (P < 0.03). CONCLUSIONS We observed a significant increase in the fat and lean body mass in all compartments and treatment groups over 36 and 60 months. Clinically irrelevant differences were found in fat distribution regardless of the treatment group and baseline characteristics. The data suggest that current antiretroviral regimens have little impact on BFD during the first years of treatment.

Abstract
Background We compared AIDS-related mortality rates in people living with HIV (PLHIV) starting antiretroviral therapy (ART) in Brazil during 2006–2015 and examined associated risk factors . Methods Data on ART use in PLHIV and AIDS mortality in Brazil was analysed with piecewise constant exponential models. Mortality rates and hazard ratios were estimated for 0–6, 6–12, 13–24, 25–36 and > 36 months of ART use and adjusted for region, age, sex, baseline CD4 cell count and calendar year of ART initiation. An additional analysis restricted to those with data on risk group was also performed. Results 269,076 individuals were included in the analysis, 165,643 (62%) males and 103,433 (38%) females, with 1,783,305 person-years of follow-up time. 21,749 AIDS deaths were reported and 8898 deaths occurred in the first year of ART. The risk of death in the first six months decreased with early ART initiation; those starting treatment early with CD4 > 500 cells per μL had a hazard ratio of 0.06 (95% CI 0.05–0.07) compared with CD4 < 200 cells per μL. Older age, male sex, intravenous drug use and starting treatment in earlier calendar years were associated with higher mortality rates. People living in the North, Northeast and South of Brazil experienced significantly higher AIDS mortality rates than those in the Southeast (HR 1.44, [95% CI 1.35–1.54], 1.10 [1.05–1.16] and 1.22 [1.17–1.28] respectively). Conclusions Early treatment is likely to have contributed to the improved survival in PLHIV on ART, with the greatest benefits observed in women, younger age-groups and those living in the North.

Abstract
Despite substantial improvement in prognosis and quality of life among people living with HIV/AIDS (PLWHA) in Brazil, inequalities in access to treatment remain. We assessed the impact of these inequalities on survival in Rio de Janeiro over a 12-year period (2000/11). Data were merged from four databases that comprise the national AIDS monitoring system: SINAN-AIDS (Brazilian Information System for Notificable Diseases; AIDS cases), SISCEL (laboratory tests), SICLOM (electronic dispensing system), and SIM (Brazilian Mortality Information System), using probabilistic linkage. Cox regressions were fitted to assess the impact of HAART (highly active antiretroviral therapy) on AIDS-related mortality among men who have sex with men (MSM), people who inject drugs (PWID), and heterosexuals diagnosed with AIDS, between 2000 and 2011, in the city of Rio de Janeiro, RJ, Brazil. Among 15,420 cases, 60.7% were heterosexuals, 36.1% MSM and 3.2% PWID. There were 2,807 (18.2%) deaths and the median survival time was 6.29. HAART and CD4+ > 200 at baseline were associated with important protective effects. Non-whites had a 33% higher risk of dying in consequence of AIDS than whites. PWID had a 56% higher risk and MSM a 11% lower risk of dying of AIDS than heterosexuals. Non-white individuals, those with less than eight years of formal education, and PWID, were more likely to die of AIDS and less likely to receive HAART. Important inequalities persist in access to treatment, resulting in disparate impacts on mortality among exposure categories. Despite these persistent disparities, mortality decreased significantly during the period for all categories under analysis, and the overall positive impact of HAART on survival has been dramatic.

Abstract
The study investigates the survival of patients with co-infection AIDS-TB through a retrospective study of a cohort of individuals aged 13 or more and the diagnosis of AIDS reported in the years 1998-99 and following 10 years. Of the 2,091 AIDS cases, 517 (24.7%) had positive diagnosis for tuberculosis, and 379 (73.3%) were male. The risk among co-infected patients was 1,65 times the not co-infected. Have been compared the exposed and non-exposed through the Kaplan-Meier and Cox method. The variables associated with longer survival were: female gender (HR = 0.63), educational level ≥ eight years (HR = 0.52), CD4 diagnostic criteria (HR = 0.64); and shorter survival: age ≥ 60 years (HR = 2.33), no use of HAART (HR = 8.62), no investigation to Hepatitis B (HR = 2.44) and opportunistic infections ≥ two (HR = 1.97). The average survival rate, related to TB infection was 69 months for the Southeast region and 73 months for the South. AIDS and tuberculosis require monitoring and treatment adherence and they are markers of the quality of care and survival of patients in Brazil.

Abstract
BACKGROUND Adherence to antiretrovirals (ARVs) is critical to achieving durable virologic suppression. OBJECTIVE To investigate risk factors of poor adherence and the effect of suboptimal adherence on health care resource utilization (HCRU) and costs in Medicaid patients. METHODS A retrospective longitudinal study was conducted using Medicaid data. Adults (aged ≥ 18 years) with human immunodeficiency virus (HIV)-1 initiating selected ARVs (index date) were identified. Adherence was measured using medication possession ratio (MPR) and proportion of days covered (PDC) at 6 and 12 months post-index. Risk factors of poor adherence (PDC < 80%) were assessed using a logistic regression. HCRU and costs were compared between suboptimal (80% ≤ PDC < 95%) and optimal (PDC ≥ 95%) adherence groups using Poisson and ordinary least square models, respectively. RESULTS In total, 3,477 patients were identified. Using MPR, 1,282 (39.0%) of the evaluable patients had poor adherence; 667 (20.2%) had suboptimal adherence; and 1,342 (40.8%) had optimal adherence versus 1,342 (51.1%), 509 (19.0%), and 804 (30.0%), respectively, using PDC at 6 months. PDC at 12 months was even lower. Younger age (OR = 1.58; 95% CI = 1.18-2.11; P = 0.002), noncapitated coverage (OR = 1.40; 95% CI = 1.16-1.69; P < 0.001), dual Medicaid/Medicare coverage (OR = 5.98; 95% CI = 4.39-8.16; P < 0.001), no baseline ARV treatment (OR = 1.98; 95% CI = 1.62-2.41; P < 0.001), and baseline asymptomatic HIV (OR = 1.37; 95% CI = 1.13-1.68; P = 0.002) were associated with higher risk of poor adherence. Suboptimal adherence patients had higher total number of days spent in a hospital (incidence rate ratio [IRR] = 1.62; 95% CI = 1.13-2.19; P = 0.008), total number of long-term care admissions (IRR = 3.11; 95% CI = 1.26-7.39; P = 0.008), total medical costs (mean monthly cost difference = $339; 95% CI = $153-$536; P < 0.001), and inpatient costs (mean monthly cost difference = $259; 95% CI = $122-$418; P < 0.001) compared with patients with optimal adherence. CONCLUSIONS Nonadherence to ARVs was observed in 60%-80% of Medicaid patients, depending on the adherence measure used, and was associated with incremental HCRU and costs. Age, insurance type and coverage, previous ARV treatment, and HIV symptoms were predictors of adherence. Treatment options that enhance adherence and prevent developing virologic failure with drug resistance should be considered for HIV patients.

Abstract
OBJECTIVE To describe the occurrence of social welfare benefits related to AIDS in Brazil and to compare the characteristics of the beneficiaries of social assistance and social security in 2004 - 2016. METHODS This was an observational, analytical study based on secondary data obtained from the Ministry of Social Security of Brazil. Sociodemographic and epidemiologic characteristics of the beneficiaries of AIDS-related social assistance and social security were analyzed. RESULTS From 2004 - 2016, a total of 99 369 benefits were granted, the majority of which were sick pay (64%), followed by social assistance benefits (26.5%) and disability retirement (8.1%). At the time that benefits were initiated, 51% of the individuals were unemployed. Those living in urban areas, females, the young, the elderly, and residents of the North and Northeast received more social assistance benefits. Duration of social assistance benefits (average 4 589 days) was greater than that of social security benefits (302 days). Survival among women (578 months) was greater than among men (311 months). CONCLUSIONS In Brazil, the profile of social welfare beneficiaries living with AIDS reveals their social vulnerability. Controlling AIDS should be a priority on public agendas, aiming to minimize the disease's social and economic impact, especially on public health, social security, and social assistance.

Abstract
Brazil's response to the HIV/AIDS epidemic was characterised by an innovative alliance of governmental and non-governmental actors inspired by a strong progressive tradition in public health. Brazil eventually moved to decentralise HIV/AIDS programmes to its states and cities, a policy endorsed and supported financially by the World Bank as consistent with the mix of public and private elements central to the country's HIV/AIDS strategy. However, decentralisation has not provided the results anticipated. Through interviews with key informants, government officials and patient advocates as well as observation of treatment sites, we outline how the shift of administration and resources to state and municipal bodies operated in practice. The Bank promoted decentralisation as an uncontroversial technical matter, and its programmatic guidelines implied that the nonprofit sector would be strengthened by it. However, instead of bringing HIV/AIDS policy closer to the grassroots, decentralisation has undermined the country's early work and opened the door to a rejuvenated epidemic by empowering unsympathetic local elites, marginalising the human rights focus, and removing federal oversight. Its experience holds crucial lessons for developing countries facing similar conditions.

Abstract
This paper examines the role of the Technical Advisory Committee for antiretroviral therapy of the Brazilian AIDS program in mediating the decision-making process of including new antiretroviral (ARV) drugs in the Unified Health System services by the end of the 2000s. We conducted documental analysis and interviews with key informants from the governmental sphere and professionals. The work features the Technical Advisory Committee as an "expert community", defined as a network of individuals with expertise and competence in a particular sphere and whose knowledge is relevant in critical public policy decision areas. It also indicates that the decision-making process for inclusion of antiretroviral drugs in the Brazilian program was incremental, considering the expectations of the innovative leader companies of pharmaceutical market. The work describes thus the results of the interaction of government interests, pharmaceutical industry and experts in the implementation of a relevant international policy. It provides arguments and evidence for understanding the role of expert communities on a sectorial public policy so far analyzed predominantly from the perspective of social movements.

Abstract
BACKGROUND Increasing genetic diversity of HIV-1 and emergence of drug-resistant mutations may reduce the efficacy of antiretroviral therapy and prophylaxis that are used to prevent mother-to-child transmission. The aim of this study was to assess the genetic diversity and prevalence of drug-resistant mutations among HIV-infected pregnant women. DESIGN AND SETTING Cross-sectional study at an outpatient clinic for infectious diseases within gynecology and obstetrics. METHODS This study evaluated the dynamics of HIV-1 subtypes and the prevalence of transmitted and acquired drug-resistant mutations among 38 HIV-infected pregnant women (20 previously exposed to antiretroviral therapy and 18 naive), in Ribeirão Preto (SP), Brazil, between 2010 and 2011. Genotyping was performed by means of molecular sequencing of the protease and reverse transcriptase regions of the HIV-1 pol gene. RESULTS Subtype B was identified in 84.2% of the samples, recombinant forms between B and F in 7.9%, subtype F1 in 5.3% and the recombinant form K/F in 2.6%. No mutation associated with transmitted drug resistance was detected in the samples from the naive pregnant women, whereas mutations associated with acquired drug resistance were found in 35.0% of the pregnant women previously exposed to antiretroviral therapy. CONCLUSION The results showed that subtype B predominated, while there was low prevalence of sequences with transmitted drug resistance.

Abstract
INTRODUCTION In the 1990s, Brazil adopted a public policy that allowed for universal, free access to antiretroviral therapy (ART). Since then, treatment adherence has become a new challenge for administrators of sexually transmitted disease/acquired immunodeficiency syndrome (STD/AIDS) policies. This study quantified adherence to ART and verified whether there is an association between sociodemographic variables and clinical/laboratory data in human immunodeficiency virus (HIV)-infected patients. METHODS This was a cross-sectional, exploratory study with a quantitative approach that was conducted over 8 months. The target population contained patients who were assisted at the ambulatory care facility specialized in STD/AIDS of a medium-size city located in Northwest São Paulo. In order to verify the level of adherence to ART, a validated CEAT-VIH (Assessment of Adherence to Antiretroviral Therapy Questionnaire) questionnaire was used. Sociodemographic aspects and clinical/laboratory data were obtained from the medical records. The results were analyzed using the Student's t-test and Pearson's coefficient. RESULTS Herein, 109 patients were interviewed, 56% of whom were male. The age of the population ranged 18-74 years (mean 45.67 years). Adherence to ART was classified as insufficient in 80.7% of cases. There was an association between ART adherence and presence of symptoms and/or opportunistic infection (p=0.008) and economic status (p<0.001). CONCLUSIONS Adherence to ART among HIV carriers cared for by the public health system is low. Patients who reported a favorable economic status and those without symptoms and/or opportunistic infection demonstrated greater treatment adherence than those who needed to take more than 3 pills a day.

Abstract
This quantitative study in the city of São Paulo, Brazil, compared contexts of social vulnerability and sexual and reproductive behavior in a sample of 975 women living with HIV/AIDS (WLHIV) and 1,003 women not living with HIV, the latter recruited among users of the primary healthcare system. WLHIV experienced situations of greater vulnerability that potentially increased their risk of HIV infection and unplanned pregnancy and abortion. Compared to women users of the primary healthcare system, WLHIV reported higher rates of drug use, sex for money, exposure to intimate partner violence, difficulties in access to services for prevention and early diagnosis, unplanned pregnancies, induced abortion, and teenage pregnancy. A considerable number of the women users of the primary healthcare system shared these same experiences, but at lower rates. The identification of contexts of vulnerability and the integration of HIV testing services with sexual and reproductive health services should constitute lines of care for these women, both in specialized and primary care services.

Abstract
The aim of this study was to investigate the modulation of plasma CXCL10, CCL20, CCL22, CCL2, CCL17 and CCL24 levels in HIV-positive patients grouped according to extreme phenotypes of progression to AIDS, and at different stages of HIV infection. HIV-positive individuals with extreme phenotypes of AIDS progression (n=58) at different clinical stages (chronic individuals, both pre-HAART and under-HAART) and HIV-negative controls (n=20) were evaluated. Additionally, HIV-positive individuals that initiated HAART with >350CD4+T-cells/mm3 were compared with those who initiated treatment with <350CD4+T-cells/mm3. Plasma levels of six chemokines were quantified by a Luminex assay. Higher CXCL10 levels were observed in individuals immediately before their CD4+T-cell levels were indicative for HAART (pre-HAART), independently of their progressor status, i.e. slow (SPs) or rapid progressors (RPs). SPs pre-HAART showed higher CXCL10 levels compared to elite controllers and RPs under HAART (pc=0.009 and pc=0.007, respectively). CXCL10 levels were higher in SPs HAART CD4<350 (initiated HAART with <350 CD4+T-cells) when compared with SPs HAART CD4>350 (initiated HAART with >350 CD4+T-cells) (1096 vs. 360.33pg/mL, p=0.0101). Normalisation of CXCL10 levels seems to depend on the CD4+T-cell nadir at HAART initiation. CCL20 levels were higher in chronic SPs, SPs pre-HAART, SPs HAART and RPs HAART compared with the HIV-negative controls, indicating persistent CCL20 expression. In conclusion, our results indicate that CXCL10 levels are a hallmark in the clinical evolution of HIV infection. However, our results must be verified in a study evaluating a larger number of AIDS progressors.

Abstract
INTRODUCTION: Bottlenecks still exist during human immunodeficiency virus care that may delay the achievement of better outcomes. METHODS: We established a monitoring system to trace patients throughout the human immunodeficiency virus/acquired immunodeficiency syndrome care process in Juiz de Fora, Brazil, to identify potential bottlenecks. RESULTS: Among 250 patients, 17.6% abandoned follow-up. Our monitoring system tracked 86.4% of patients through the medication logistics control system and 2.3% through the mortality information system. Two percent of patients were not located by our monitoring system. CONCLUSIONS: A pathway care process contributes to a better understanding of the barriers to the treatment cascade.

Abstract
OBJECTIVE To describe the antiretroviral therapy status of people living with HIV (PLHIV) who died of AIDS-related causes between 2009 and 2013. METHODS We conducted a cross-sectional, population-based study. Data were obtained by linking the mortality information system and the national ART dispensing database. Trends were modelled using linear regression analysis. RESULTS A total of 61 425 AIDS-related deaths were registered in Brazil between 2009 and 2013. Median age at death was 41 years (IQR: 33-49), and 65.7% (40 337) of deaths were among men; 47.2% (29 004) of PLHIV who died during the study period had never started treatment, 7.0% (4274) had discontinued it, 15.9% (9775) were on ART for 6 months or less and 29.9% (18 372) were on ART for more than 6 months. Only 1.3% of PLHIV were on third-line ARV regimens when they died. CONCLUSIONS AIDS-related mortality remains a challenge even in a context of sustained universal access to antiretroviral treatment due to failure of service provision, not to therapy failure. Robust health policies closing gaps in the HIV continuum of care are crucial to further reduce mortality.

Abstract
Retention in early HIV care has been associated with decreased mortality and improved viral suppression, however the consequences of poor retention in early care in Brazil remain unknown. We assessed the effect of poor retention on mortality in a Brazilian HIV-infected clinical cohort. The analysis included ART-naïve, HIV-infected adults linked to care at the Instituto Nacional de Infectologia Evandro Chagas, Fundação Oswaldo Cruz between 2000 and 2010, who did not become pregnant nor participate in a clinical trial during the first two years in care (early care). Poor retention in early care was defined as less than 3 out of 4 six-month intervals with a CD4 or HIV-1 RNA laboratory result during early care. Cox proportional hazards models were used to identify factors associated with mortality, and Kaplan-Meier plots were used to describe the survival probability for participants with poor retention versus good retention. Among 1054 participants with a median (interquartile range) follow-up time of 4.2 years (2.6, 6.3), 20% had poor retention in early care and 8% died. Poor retention in early care [adjusted hazard ratio (aHR) 3.09; 95% CI 1.65-5.79], AIDS defining illness (aHR 1.95; 95% CI 1.20-3.18) and lower education (aHR 2.33; 95% CI 1.45-3.75) were associated with increased mortality risk. Our findings highlight the importance of adopting strategies to improve retention in early HIV care.

Abstract
Background Before antiretroviral therapy (ART) became widely available in sub-Saharan Africa, several studies demonstrated that daily trimethoprim-sulfamethoxazole (TS) prophylaxis reduced morbidity and mortality among HIV-infected adults. As a result, the World Health Organization (WHO) recommended administering TS prophylaxis to this group. However, the applicability of the results to individuals taking ART and living in sub-Saharan Africa has not been definitively evaluated. This study aims to determine if TS prophylaxis benefits HIV-infected Malawian adults after a good response to ART. If TS prophylaxis does indeed show benefit, it is important to determine if this is due to its antibacterial and/or antimalarial properties. Methods/design A randomized, controlled, open-label, phase III trial of continued standard of care prophylaxis with daily trimethoprim-sulfamethoxazole (TS) compared to discontinuation of standard of care TS prophylaxis and starting weekly chloroquine (CQ) prophylaxis or discontinuation of standard of care TS prophylaxis. The study will randomize 1400–1500 HIV-infected adults (equally divided over the three study arms) with a nondetectable viral load and a CD4 count of 250/mm3 or more from antiretroviral therapy clinics in Blantyre and Zomba. The expected rate of primary endpoint events of death and WHO stage 3 and 4 events is 6.8 per 100 person-years of follow-up in all participants. Assuming the number of events follows a Poisson distribution and average participant follow-up after 10 % loss to follow-up is 41.6 months, the study will have approximately 85 % power to rule out a reduction of 35 % or more in primary endpoint events in the TS or CQ arms compared to discontinuation of TS prophylaxis—i.e., to show that discontinuation of TS prophylaxis is noninferior to either TS or CQ, with a noninferiority margin of 35 %. Ethical and regulatory approvals were obtained from the University of Malawi College of Medicine Research Ethics Committee; the Malawi Pharmacy, Medicines and Poisons Board; and the University of Maryland Baltimore Institutional Review Board. Discussion The study began recruitment activities at the Ndirande site in November 2012. The sponsor agreed to extend and expand the study in early 2015, and a second site, Zomba, was added for recruitment and follow-up in mid-2015. Trial registration ClinicalTrials.gov Identifier: NCT01650558 (registered on 6 July 2012).

Abstract
INTRODUCTION There are multiple reasons to switch from a virologically successful antiretroviral regimen. Some of them are related to toxicity. Lately, combination antiretroviral treatment (cART) switches have often been related to drug-drug interactions which may also eventually entail safety issues as well. AREAS COVERED The purpose of this review is to analyze causes of switching between virologically successful cART regimes related to safety issues. The most relevant papers were selected and summarized. EXPERT OPINION Switching cART has been a popular strategy to address safety issues throughout the antiretroviral era. The myriad of switching studies have paralleled the study and release into clinical practice of new antiretroviral drugs with different and often improved safety profiles. Most of them have been successful in improving antiretroviral toxicity while keeping HIV replication under control. However, it should be taken into account that, whenever a new drug is given, there is a possibility of new drug-related toxicity. Notwithstanding that, an increase in cART switching is foreseen, given the fact that we have a wide antiretroviral drug armamentarium and that people living with HIV are ageing and thus more prone to developing age-related co-morbidities whose therapies may entail new interactions and eventually new toxicities.

Abstract
Objective In Brazil, universal provision of antiretroviral therapy (ART) has been guaranteed free of charge to eligible HIV-positive patients since December 1996. We sought to quantify the survival benefits of ART attributable to this programme. Methods We used a previously published microsimulation model of HIV disease and treatment (CEPAC-International) and data from Brazil to estimate life expectancy increase for HIV-positive patients initiating ART in Brazil. We divided the period of 1997 to 2014 into six eras reflecting increased drug regimen efficacy, regimen availability and era-specific mean CD4 count at ART initiation. Patients were simulated first without ART and then with ART. The 2014-censored and lifetime survival benefits attributable to ART in each era were calculated as the product of the number of patients initiating ART in a given era and the increase in life expectancy attributable to ART in that era. Results In total, we estimated that 598,741 individuals initiated ART. Projected life expectancy increased from 2.7, 3.3, 4.1, 4.9, 5.5 and 7.1 years without ART to 11.0, 17.5, 20.7, 23.0, 25.3, and 27.0 years with ART in Eras 1 through 6, respectively. Of the total projected lifetime survival benefit of 9.3 million life-years, 16% (or 1.5 million life-years) has been realized as of December 2014. Conclusions Provision of ART through a national programme has led to dramatic survival benefits in Brazil, the majority of which are still to be realized. Improvements in initial and subsequent ART regimens and higher CD4 counts at ART initiation have contributed to these increasing benefits.

Abstract
INTRODUCTION Universal coverage of highly active antiretroviral therapy (HAART) for HIV/AIDS in Mexico was achieved in a staggered fashion. First, HAART was made available in 1997 for employees in the formal sector and subsequently, in 2003, for informal sector workers and the unemployed population. We evaluated the impact of this free universal HAART program on HIV/AIDS mortality in the Mexican population aged 15 years or older. METHODS Time-series cross-sectional data analysis of standardized HIV/AIDS mortality rates (1990-2011) using marginal linear models with inflection points at 1994, 1997, and 2003. RESULTS Men employed in the formal sector experienced the greatest effect of access to HAART, with a 32% reduction in mortality from 1997 to 2011 (P < 0.01). For men in this sector, mortality increased from 1990 to 2003, then stabilizing at 7 deaths per 100,000. For women in the informal sector, mortality increased from 1990 to 2011. We found large between-state variability: mortality decreased by 59% in Mexico City while it increased by 245% in Tabasco during the study period. Six of 32 states achieved statistically significant reductions in mortality while 5 states continued to experience increasing mortality rates despite universal HAART. CONCLUSIONS Access to universal HAART has had relative success in Mexico. The heterogeneity of HIV/AIDS mortality by employment status, gender, and state of residence highlight urgent needs to improve health equity with pro-poor and gender-responsive programs and a call for country-specific operational research in HIV/AIDS prevention and treatment. Our results may apply to other countries seeking to implement universal access to antiretroviral therapy.

Abstract
We conducted a time-location sampling sero-behavioral surveillance survey of men who have sex with men (MSM) in São Paulo, Brazil, the largest city in Latin America and the Southern Hemisphere (N = 1,217 interviewed with serological results for 771). HIV prevalence was 15.4 % (95 % CI 11.6-20.1), with only 45.8 % previously aware of their infection. HIV prevalence achieved 6.4 % among youth 18-24 years and was higher among MSM with lower socio-economic status. In multivariate analysis, correlates of HIV were older age, gay identity, lower socio-economic status, social networks with HIV-positive MSM, receptive anal sex, and internet sex partners. Policy change towards increasing avenues for HIV testing coupled with antiretroviral treatment regardless of CD4 count or stage of disease stand to benefit the MSM community if scaled up fast enough.

Abstract
A retrospective cohort study was conducted to explore the effectiveness of Traditional Chinese Medicine (TCM) in treating people living with HIV (PLHIV) by comparing the survival of PLHIV treated with TCM and without TCM. To identify prognostic factors that affect the survival of PLHIV, patients who enrolled in the national TCM HIV treatment trial program (NTCMTP) in October 2004 and PLHIV in the same region who did not enroll in the NTCMTP were compared. Participants were followed up to October 2012. Survival time was estimated through the Kaplan-Meier method, and hazard ratios to identify prognostic factors were computed through Cox proportional hazard models. A total of 3,229 PLHIV (1,442 in the TCM therapy group and 1,787 in the non-TCM therapy group) were followed up for 21,876 person-years. In this time period, 751 (23.3%) died and 209 (6.5%) were lost to follow-up, for an overall mortality rate of 3.43/100 person-years. In the TCM therapy group, 287 (19.0%) died and 139 (9.7%) were lost to follow-up, and in the non-TCM therapy group, 464 (26.0%) PLHIV died and 70 (3.9%) were lost to follow-up. The mortality rate in the TCM therapy group was 2.97/100 person-years, which was lower than the rate of 3.79/100 person-years in the non-TCM therapy group. The 8-year cumulative survival in the TCM therapy group was 78.5%, lower than the 74.0% survival in the non-TCM therapy group. After adjusting for other factors, risk factors of death included male gender, older age, less education, taking combined antiretroviral therapy (cART) at enrollment, not taking cART at follow-up, and lower CD4 + T cell counts. Our retrospective cohort study indicates that TCM increased the survival and lengthened the lifetime of PLHIV in Henan Province of China. However, the limitations of a retrospective cohort could have biased the study, so prospective studies should be carried out to confirm our primary results.

Abstract
Introduction Since 1996 Brazil has provided universal access to free antiretroviral therapy, and as a consequence, HIV/AIDS patients’ survival rate has improved dramatically. However, according to scientific reports, a significant number of patients are still late presenting for HIV treatment, which leads to consequences both for the individual and society. Clinical and immunological characteristics of HIV patients newly diagnosed were accessed and factors associated with late presentation for treatment were evaluated. Methods A cross-sectional study was carried out in an HIV/AIDS reference center in Belo Horizonte, Minas Gerais, in Southeastern Brazil from 2008 to 2010. Operationally, patients with late presentation (LP) for treatment were those whose first CD4 cell count was less than 350 cells/mm3 or presented an AIDS defining opportunistic infection. Patients with late presentation with advanced disease (LPAD) were those whose first CD4 cell count was less than 200 cells/mm3 or presented an AIDS defining opportunistic infection. LP and LPAD associated risk factors were evaluated using logistic regression methods. Results Five hundred and twenty patients were included in the analysis. The median CD4 cell count was 336 cells/mm3 (IQR: 130–531). Two hundred and seventy-nine patients (53.7%) were classified as LP and 193 (37.1%) as LPAD. On average, 75% of the patients presented with a viral load (VL) >10,000 copies/ml. In multivariate logistic regression analysis the factors associated with LP and LPAD were age, being symptomatic at first visit and VL. Race was a factor associated with LP but not with LPAD. Conclusion The proportion of patients who were late attending a clinic for HIV treatment is still high, and effective strategies to improve early HIV detection with a special focus on the vulnerable population are urgently needed.

Improvement of HAART in Brazil, 1998-2008: a nationwide assessment of survival times after AIDS diagnosis among men who have sex with men. BMC Public Health 2015; 15:226. [PMID: 25886530 PMCID: PMC4369842 DOI: 10.1186/s12889-015-1530-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2014] [Accepted: 02/13/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In 1996, Brazil became the first developing country to provide free, universal access to HAART, laboratory monitoring, and clinical care to any eligible patient. As of June 2014, approximately 400,000 patients were under treatment, making it the most comprehensive HIV treatment initiative implemented thus far in a middle-income country, worldwide. The Brazilian epidemic is highly concentrated among men who have sex with men (MSM). METHODS Four national information systems were combined and Cox regression was used to conduct retrospective cohort analysis of HAART availability/access on all-cause mortality among MSM diagnosed with AIDS reported to the information systems between 1998-2008, adjusting for demographic, clinical, and behavioral factors and controlling for spatially-correlated survival data by including a frailty effect. Multiple imputation by chained equations was used to handle missing data. RESULTS Among 50,683 patients, 10,326 died during the 10 year of period. All-cause mortality rates declined following introduction of HAART, and were higher among non-white patients and those starting HAART with higher viral load and lower CD4 counts. In multivariable analysis adjusted for race, age at AIDS diagnosis, and baseline CD4 cell count, MSM diagnosed in latter periods had almost a 50% reduction in the risk of death, compared to those diagnosed between 1998-2001 (2002-2005 adjHR: 0.54, 95% CI:0.51-0.57; 2006-2008 adjHR: 0.51, 95% CI:0.48-0.55). After controlling for spatially correlated survival data, mortality remained higher among those diagnosed in the earliest diagnostic cohort and lower among non-white patients and those starting HAART with higher viral load and lower CD4 lymphocyte counts. CONCLUSIONS Universal and free access to HAART has helped achieve impressive declines in AIDS mortality in Brazil. However, after a 10-years follow-up, differential AIDS-related mortality continue to exist. Efforts are needed to identify and eliminate these health disparities, therefore improving the Brazilian response towards HIV/AIDS epidemic.

Abstract
Background the impact of human immunodeficiency virus type 1 (HIV-1) on lung function is well known and associated with a reduction in pulmonary ventilation. Moreover, the use of highly active antiretroviral therapy has been associated with mitochondrial dysfunction and decreased muscle strength. However, there is scarce information about the factors associated with inspiratory muscle weakness in these patients. Objective the purpose of the present study was to investigate the factors associated with inspiratory muscle weakness in patients with HIV-1. Methods two-hundred fifty seven patients with HIV-1 were screened and categorized into two groups: (1) IMW+ (n = 142) and (2) IMW− (n = 115). Lung function (FEV1, FVC and FEV1/FVC), maximum inspiratory pressure, distance on the six-minute walk test and CD4 cell count were assessed. Results the mean duration of HIV infection was similar in the two groups. The following variables were significantly different between groups: mean duration of highly active antiretroviral therapy (81 ± 12 in IMW+ versus 38 ± 13 months in IMW−; p = 0.01), and CD4 cell count (327 ± 88 in IMW+ versus 637 ± 97 cells/mm3 in IMW−; p = 0.02). IMW+ presented reduced lung function (FEV1, FVC, FEV1/FVC). Conclusion patients with IMW+ had lower distance on the six-minute walk test in comparison to the IMW− group. The duration of highly active antiretroviral therapy, distance traveled on the 6MWT and CD4 count were determinants of IMW in patients with HIV.

Abstract
Poverty and altered planning horizons brought on by the HIV/AIDS epidemic can change individual discount rates, altering incentives to conserve natural resources. Using longitudinal household survey data from western Kenya, we estimate the effects of health status on investments in soil quality, as indicated by households' agricultural land fallowing decisions. We first show that this effect is theoretically ambiguous: while health improvements lower discount rates and thus increase incentives to conserve natural resources, they also increase labor productivity and make it more likely that households can engage in labor-intensive resource extraction activities. We find that household size and composition are predictors of whether the effect of health improvements on discount rates dominates the productivity effect, or vice-versa. Since households with more and younger members are better able to reallocate labor to cope with productivity shocks, the discount rate effect dominates for these households and health improvements lead to greater levels of conservation. In smaller families with less substitutable labor, the productivity effect dominates and health improvements lead to greater environmental degradation.

Abstract
One of the main aspects related to non-adherence to combined antiretroviral therapy (cART) for patients infected with the Human Immunodeficiency Virus (HIV) refers to the abandonment of outpatient care. This study was aimed to estimate the loss to follow-up in outpatient HIV care at a Regional Referral Clinic (SAE) for HIV/AIDS in the city of Juiz de Fora, Brazil, and to identify associated factors and predictors. This is a prospective cohort of patients older than 18 years, under cART and regular outpatient care. The study included patients who attended medical visits during July-August 2011. Those who did not return to the clinic for new medical appointments within 90 days after the sixth month of follow up were considered lost to follow-up in outpatient care. Variables with P value ≤0.25 in the univariate analysis were included in a logistic regression model, adopting a significance level of 0.05. Among the 250 patients included in the study, 44 (17.6 %) were lost to follow up in outpatient care. Among these, 38 (86.4 %) were located in the cART delivery database system (SICLOM). Younger patients (≤43 versus >43 years) (OR 2.30 CI 1.06-5.00, P = 0.04), and patients attended by physician "E", when compared with physicians "A", "B", "C" or "D" (OR 5.90 CI 2.64-13.18, P = 0.00) were more likely to be lost to follow-up. Patients admitted in the service for 7 years or more were also more likely to be to lost to follow-up (OR 2.27 CI 1.2-4.4, P = 0.01), although this association did not remain statistically significant in the multivariate analysis. Although the purpose of the study, to identify individual factors associated to loss to follow-up, positives associations with a specific physician and with patients admitted in the service for 7 years or more suggest organizational factors. Although the majority of patients lost to follow-up in outpatient care were detected by SICLOM, a detectable viral load in most of these patients suggest a quality of outpatient HIV care proved ineffective, despite the availability of cART. We conclude on the need for further studies to investigate structural factors associated to loss to follow-up when enhanced retention strategies should be implemented in order to maintain an effective outpatient HIV care.

Abstract
BACKGROUND Brazil was the first middle-income country to provide free and universal access to AIDS treatment. Understanding the impact of this policy is key to promote ongoing improvement of current intervention strategies. The aim of this study was to compare mortality rates and survival in a cohort of AIDS patients before and after the introduction of antiretrovirals (ARV) and to investigate predictors of survival. METHODS A retrospective cohort study of AIDS patients aged 13 years or more living in the city of Sao Paulo was conducted. All patients were recruited from an STD/HIV outpatient clinic between 1988 and 2003 and followed up until 2005. We estimated AIDS mortality rates in person-years (py) and carried out a survival analysis using the Kaplan-Meier method. The Cox proportional hazards model was used to assess predictors of survival in AIDS patients. RESULTS The study cohort comprised 6,594 patients. The yearly mean mortality rates were 17.6, 23.2, and 7.8 per 1,000 py for the study periods 1988-1993, 1994-1996, and 1997-2003, respectively. Median survival time was 13.4 and 22.3 months for patients entering the study in the first and second study periods and survival time was 108 months or more in 72% of those entering the study during 1997-2003. Factors independently associated with shorter survival included: AIDS diagnosis during the 1994-1996 (HR 2.0) and 1988-1993 (HR 3.2) periods; 50 years of age or more (HR 2.0); exposure category of injection drug users (IDU) (HR 1.5); 8 years of schooling or less (HR 1.4); no schooling (HR 2.1); and CD4+ counts between 350 and 500 cells/mm(3) (HR 1.2) and less than 350 cells/mm(3) at AIDS diagnosis (HR 1.3). CONCLUSIONS The study showed a strong impact following the introduction of HAART in 1996 with decreased AIDS mortality, increased survival rates, and benefits with early introduction of HAART. However, some groups of patients were less likely to benefit from the new drug regimens. Public policies promoting health equity create an enabling environment helping AIDS control programs in developing countries to achieve their goals as effectively as in developed countries.

Abstract
Combination antiretroviral therapy (cART) has been widely available in Ghana since 2004. The aim of this cohort study was to assess the incidences of death, AIDS-defining events and non-AIDS defining events and associated risk factors amongst patients initiating cART in a large treatment centre. Clinical and laboratory data were extracted from clinic and hospital case notes for patients initiating cART between 2004 and 2010 and clinical events graded according to recognised definitions for AIDS, non-AIDS events (NADE) and death, with additional events not included in such definitions such as malaria also included. The cumulative incidence of events was calculated using Kaplan Meier analysis, and association of risk factors with events by Cox proportional hazards regression. Data were closed for analysis on 31st December, 2011 after a median follow-up of 30 months (range, 0-90 months). Amongst 4,039 patients starting cART at a median CD4 count of 133 cells/mm3, there were 324 (8%) confirmed deaths, with an event rate of 28.83 (95% CI 25.78-32.15) deaths per 1000-person follow-up years; the commonest established causes were pulmonary TB and gastroenteritis. There were 681 AIDS-defining events (60.60 [56.14-65.33] per 1000 person years) with pulmonary TB and chronic diarrhoea being the most frequent causes. Forty-one NADEs were recorded (3.64 [2.61-4.95] per 1000 person years), of which hepatic and cardiovascular events were most common. Other common events recorded outside these definitions included malaria (746 events) and respiratory tract infections (666 events). Overall 24% of patients were lost-to-follow-up. Alongside expected risk factors, stavudine use was associated with AIDS [adjusted HR of 1.08 (0.90-1.30)] and death (adjusted HR of 1.60 [1.21-2.11]). Whilst frequency of AIDS and deaths in this cohort were similar to those described in other sub-Saharan African cohorts, rates of NADEs were lower and far exceeded by events such as malaria and respiratory tract infections.

Abstract
Patients treated in the specialized service at a midsized city in Brazil participated in a cross-sectional study that aimed to identify the risk factors for delayed diagnosis of HIV/AIDS. Through interviews and review of medical records, information was collected on sociodemographic and clinical characteristics and diagnoses. The study included 403 patients, of whom 216 (53.6%) were male and 311 (77.1%) had ≤8 years of education. According to the criteria adopted in this study, 162 (40.2%) of the participants had a late diagnosis of AIDS. Only 19 (4.7%) were diagnosed by routine examinations and 45 (11.2%) presented with AIDS-defining disease at the time of diagnosis. After adjustments, the results showed that having more education was protective against a late diagnosis for women. With the advance of the AIDS epidemic to small town and rural Brazil, vulnerable populations now include low-income and less educated women, most of whom have had monogamous relationships throughout their lives.

Abstract
INTRODUCTION Smoking is the leading cause of preventable death in the world. The prevalence of smoking is higher in people infected with HIV than in the general population. Although it is biologically plausible that smoking increases the morbidity and mortality of people living with HIV/AIDS, few studies in developing countries have analyzed the determinants and consequences of smoking in HIV infected people. OBJECTIVE To estimate the prevalence of smoking and identify the socioeconomic factors associated with smoking and smoking cessation in patients with HIV by sex. METHODS A cross-sectional study was conducted with baseline data, obtained from an ongoing prospective cohort study of patients with HIV attending two referral centers in Recife, Northeast Region of Brazil, between July 2007 and October 2009. RESULTS The prevalence of current smoking was 28.9%. For both sexes, smoking was independently associated with heavy alcohol drinking and marijuana use. Among women, smoking was associated with living alone, not being married and illiteracy; and among men, being 40 years or older, low income and using crack. Compared with ex-smokers, current smokers were younger and more likely to be unmarried, heavy drinkers and marijuana users. CONCLUSIONS It is important to incorporate smoking cessation interventions for the treatment of heavy alcohol drinkers and marijuana users with HIV/AIDS, which may increase life expectancy and quality of life, as smoking is related to risk of death, relapse of tuberculosis, and non communicable diseases.

Abstract
BACKGROUND While Brazil has had a long-standing policy of free access to antiretroviral therapy (ART) for all in need, the epidemiological impact of ART on human immunodeficiency virus (HIV) RNA suppression in this middle-income country has not been well evaluated. We estimate first-line ART effectiveness in a large Brazilian cohort and examine the socio-demographic, behavioral, clinical and structural factors associated with virologic suppression. METHODS Virologic suppression on first-line ART at 6, 12, and 24 months from start of ART was defined as having a viral load measurement ≤400 copies/mL without drug class modification and/or discontinuation. Drug class modification and/or discontinuation were defined based on the class of a particular drug. Quasi-Poisson regression was used to quantify the association of factors with virologic suppression. RESULTS From January 2000 through June 2010, 1311 patients started first-line ART; 987 (75%) patients used NNRTI-based regimens. Virologic suppression was achieved by 77%, 76% and 68% of patients at 6, 12 and 24 months, respectively. Factors associated with virologic suppression at 12 months were: >8 years of formal education (compared to <4 years, risk ratio (RR) 1.13, 95% confidence interval (95% CI) 1.03-1.24), starting ART in 2005-2010 (compared to 2000-2004, RR 1.25 95% CI 1.15-1.35), and clinical trial participation (compared to no participation, RR 1.08 95% CI 1.01-1.16). Also at 12 months, women showed less virologic suppression compared to heterosexual men (RR 0.90 95% CI 0.82-0.99). For the 24-month endpoint, in addition to higher education, starting ART in the later period, and clinical trial participation, older age and an NNRTI-based regimen were also independently associated with virologic suppression. CONCLUSIONS Our results show that in Brazil, a middle-income country with free access to treatment, over three-quarters of patients receiving routine care reached virologic suppression on first-line ART by the end of the first year. Higher education, more recent ART initiation and clinical trial participation were associated with improved outcomes both for the 12-month and the 24-month endpoints, suggesting that further studies are needed to understand what aspects relating to these factors lead to higher virologic suppression.

[PMID: 25074393 DOI: 10.1038/ejcn.2014.149] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2013] [Revised: 06/23/2013] [Accepted: 06/26/2014] [Indexed: 11/08/2022]
Abstract
OBJECTIVES To propose objective ratios using anthropometry and dual-energy X-ray absorptiometry (DXA) and to suggest cutoff points for them in order to classify lipodystrophy in male patients. METHODS It is a cross-sectional study. DXA was applied and anthropometric measurements were performed in 100 men on highly active antiretroviral therapy. Receiver operating characteristic curves were used to propose cutoffs. Individuals were divided in without (lipo-) or with (lipo+) lipodystrophy and their metabolic parameters were compared. RESULTS The following ratios were proposed: fat mass ratio by DXA (FMR), waist thigh ratio (WTR), waist calf ratio (WCR), and arm to trunk ratio (ATR). The best cutoffs observed for FMR, WTR and ATR were 1.26, 1.74 and 2.08, respectively. Using the proposed cutoff for FMR, we observed worse metabolic profile, with increased tryglicerides, fasting serum glucose and more hypercholesterolemia in the lipo+ group. WTR and ATR showed a significant correlation with FMR. CONCLUSIONS Anthropometric ratios (WTR/ATR) and FMR can be used to aid the diagnosis of lipodystrophy in order to contribute to a more accurate and earlier diagnosis permitting intervention and even preventing metabolic disturbances.

Abstract
The prognosis of human immunodeficiency virus (HIV)-infected individuals has dramatically improved worldwide since the introduction of highly antiretroviral therapy. Nevertheless, along with the decrease in mortality, several body modifications not initially related to HIV infection have been reported. Disorders in lipid and glucose metabolism, accompanied by body shape abnormalities and alterations in fat distribution, began to be described. A syndrome, named "HIV-associated lipodystrophy syndrome", was coined to classify these clinical spectrum aspects. This syndrome involves not only metabolic alterations but also fat redistribution, with lipoatrophy due to subcutaneous fat loss (predominantly in the face and lower limbs) and lipohypertrophy related to central fat gain. These changes in body shape are very important to be recognized, as they are associated with worse morbidity and mortality. Self-esteem difficulties related to body alterations might lead to treatment failures due to medication adherence problems. Moreover, these alterations have been associated with an increased risk of cardiovascular events. Therefore, it is extremely important to identify this syndrome early in order to provide an even better quality of life for this population, as the clinical approach is not easy. Treatment change, medications to treat dyslipidemia, and surgical intervention are instruments to be used to try to correct these abnormalities. The aim of this study is to review clinical presentation, diagnosis, and management of body shape and metabolic complications of HIV infection from a Brazilian perspective, a medium income country with a large number of patients on antiretroviral therapy.

Abstract
The trend towards decline and stabilization of the AIDS epidemic in Brazil should be analyzed carefully, since aggregate data can mask regional or local inequalities in such a large and diverse country. The current study reevaluates the epidemic’s spatial dissemination and the AIDS-related mortality pattern in Brazil. The study considered all AIDS cases diagnosed in individuals over 18 years of age and living in Brazil, as well as AIDS deaths recorded in 1998-2008. Three-year moving average rates were estimated, and a spatial analysis was conducted using a local empirical Bayesian method. The epidemic was only found to be expanding in the North and Northeast regions, while declining in the rest of the country, especially in the Southeast. According to the findings, the apparent stabilization of AIDS mortality tends to mask regional disparities. Social determinants of health and regional disparities should be taken into account in program development and policymaking.

Abstract
Dyslipidemia has been frequently observed among individuals infected with human immunodeficiency virus type 1 (HIV-1), and factors related to HIV-1, the host, and antiretroviral therapy (ART) are involved in this phenomenon. This study reviews the roles of genetic polymorphisms, HIV-1 infection, and highly active antiretroviral therapy (HAART) in lipid metabolism. Lipid abnormalities can vary according to the HAART regimen, such as those with protease inhibitors (PIs). However, genetic factors may also be involved in dyslipidemia because not all patients receiving the same HAART regimen and with comparable demographic, virological, and immunological characteristics develop variations in the lipid profile. Polymorphisms in a large number of genes are involved in the synthesis of structural proteins, and enzymes related to lipid metabolism account for variations in the lipid profile of each individual. As some genetic polymorphisms may cause dyslipidemia, these allele variants should be investigated in HIV-1-infected patients to identify individuals with an increased risk of developing dyslipidemia during treatment with HAART, particularly during therapy with PIs. This knowledge may guide individualized treatment decisions and lead to the development of new therapeutic targets for the treatment of dyslipidemia in these patients.

Survival analysis of acquired immune deficiency syndrome patients with and without hepatitis C virus infection at a reference center for sexually transmitted diseases/acquired immune deficiency syndrome in São Paulo, Brazil. Braz J Infect Dis 2013; 18:150-7. [PMID: 24211628 PMCID: PMC9427469 DOI: 10.1016/j.bjid.2013.06.006] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2013] [Accepted: 06/30/2013] [Indexed: 01/28/2023] Open
Abstract
INTRODUCTION Survival of patients with acquired immune deficiency syndrome has improved with combination antiretroviral therapy; mortality due to liver diseases, however, has also increased in these patients. OBJECTIVES To estimate the accumulated probability of survival in human immunodeficiency virus-hepatitis C virus coinfected and non-coinfected patients and to investigate factors related to acquired immune deficiency syndrome patients' survival. METHODS Non-concurrent cohort study using data from surveillance information systems of acquired immune deficiency syndrome patients over 13 years of age. Hepatitis C and B, human immunodeficiency virus exposure category, CD4+ T cell count, age group, schooling, race, sex, and four acquired immune deficiency syndrome diagnosis periods were studied. Kaplan-Meier survival analysis and Cox model with estimates of the hazard ratio and 95% confidence interval were used. RESULTS Of the total 2864 individuals included, with median age was 35 years, 219 died (7.5%), and 358 (12.5%) were human immunodeficiency virus-hepatitis C virus coinfected. The accumulated probability of survival in human immunodeficiency virus-hepatitis C virus coinfected patients, after acquired immune deficiency syndrome diagnosis, at 120 months, was 0%, 38.9%, 83.8% in 1986-1993, 1994-1996, 1997-2002, respectively, and 92.8% at 96 months in 2003-2010; survival in non-coinfected patients at 120 months was 80%, 90.2%, 94% in 1986-1993, 1994-1996, 1997-2002, respectively, and 94.1% at 96 months in 2003-2010. In the multivariate model the following variables were predictive of death: hepatitis C virus coinfection (hazard ratio=2.7; confidence interval 2.0-3.6); Hepatitis B virus coinfection (hazard ratio=2.4; confidence interval 1.7-3.6); being ≥ 50 years old (hazard ratio=2.3; confidence interval 1.3-3.8); having 8-11 years of schooling (hazard ratio=1.6; confidence interval 1.1-2.3), having 4-7 years of schooling (hazard ratio=1.9; confidence interval 1.3-2.8) and having up to 3 years of schooling (hazard ratio=3.3; confidence interval 2.0-5.5). CONCLUSIONS Among patients diagnosed after 1996, there was a significant increase in the cumulative probability of survival in human immunodeficiency virus-hepatitis C virus coinfected individuals; among those diagnosed with acquired immune deficiency syndrome from 2003 to 2010, this probability was similar between coinfected and non-coinfected patients.

Survival and Prognostic Factors for AIDS and Non-AIDS Patients with Non-Hodgkin's Lymphoma in Bahia, Brazil: A Retrospective Cohort Study. ISRN HEMATOLOGY 2013; 2013:904201. [PMID: 24288620 PMCID: PMC3830808 DOI: 10.1155/2013/904201] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/21/2013] [Accepted: 08/07/2013] [Indexed: 11/24/2022]
Abstract
Despite the benefits of HAART, HIV-infected patients are increasingly affected by different malignancies. We compared a 5-year-period survival time and prognostic factors for HIV-1-infected individuals diagnosed with non-Hodgkin lymphomas (NHL) in a nested case-control study, with non-HIV-infected individuals in Salvador, Brazil. Survival time and prognostic factors were compared to HIV-negative patients. 31 cases (versus 63 controls) had a significantly more advanced NHL at diagnosis and lower mean CD4 count (26 cells/mm3) than controls. Mean overall survival (OS) was 35.8 versus 75.4 months, for cases and controls, respectively (P < 0.001), while mean event-free survival time (EFS) was 34.5 months for cases, versus 68.8 for controls (P = 0.002). Higher IPI, increased LDH levels, bone marrow infiltration, lower absolute lymphocyte counts (<1,000 cells/mm3), and type B symptoms were associated with a shorter survival time for cases. Although patients without poorer prognostic factors at baseline had an OS comparable to controls, the mean CD4 cell count for cases was similar for patients with favorable and nonfavorable response to therapy. Our findings suggest that HIV-1 infection is significantly associated with a shorter survival time for patients with NHL, independently of other predictive factors and of disease stage.

Genetic markers associated to dyslipidemia in HIV-infected individuals on HAART. ScientificWorldJournal 2013; 2013:608415.

Abstract
This study evaluated the impact of 9 single nucleotide polymorphisms (SNPs) in 6 candidate genes (APOB, APOA5, APOE, APOC3, SCAP, and LDLR) over dyslipidemia in HIV-infected patients on stable antiretroviral therapy (ART) with undetectable viral loads. Blood samples were collected from 614 patients at reference services in the cities of Porto Alegre, Pelotas, and Rio Grande in Brazil. The SNPs were genotyped by conventional polymerase chain reaction (PCR) and real-time PCR. The prevalence of dyslipidemia was particularly high among the protease inhibitors-treated patients (79%). APOE (rs429358 and rs7412) genotypes and APOA5 −1131T>C (rs662799) were associated with plasma triglycerides (TG) and low-density-lipoprotein cholesterol levels (LDL-C). The APOA5 −1131T>C (rs662799) and SCAP 2386A>G (rs12487736) polymorphisms were significantly associated with high-density-lipoprotein cholesterol levels. The mean values of the total cholesterol and LDL-C levels were associated with both the APOB SP Ins/Del (rs17240441) and APOB XbaI (rs693) polymorphisms. In conclusion, our data support the importance of genetic factors in the determination of lipid levels in HIV-infected individuals. Due to the relatively high number of carriers of these risk variants, studies to verify treatment implications of genotyping before HAART initiation may be advisable to guide the selection of an appropriate antiretroviral therapy regimen.
