Incidence and Clinical Description of Lymphomas in Children and Adolescents with Vertical Transmission of HIV in Rio de Janeiro, Brazil, in Pre- and Post-Combined Antiretroviral Therapy Eras: A Multicentric Hospital-Based Survival Analysis Study. Cancers (Basel) 2022; 14:cancers14246129. [PMID: 36551614 PMCID: PMC9776495 DOI: 10.3390/cancers14246129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 11/25/2022] [Accepted: 12/06/2022] [Indexed: 12/15/2022] Open
Abstract
The incidence of cancer in children living with HIV (CLWH) is high and lymphomas are the most common type of cancer in this population. The combined antiretroviral therapy (cART) changed the natural history of HIV infection. To determine the incidence and profile of these CLWH malignancies in Rio de Janeiro (RJ), Brazil, we conducted a retrospective and observational study of vertically infected CLWH, ranging from 0−20 incomplete years, from 1995 to 2018, at five reference centers. The study period was divided into three eras in accordance with the widespread use of cART in Brazil. 1306 patients were included. Of the 25 lymphomas found, 19 were AIDS-defining malignancies (ADM); 6 were non-AIDS-defining malignancies (NADM). The incidence rate (IR) of lymphoma developing was 1.70 per 1000 children-year (95% CI 1.09−2.50). ADM development IR decreased from 2.09−1.75−0.19 per 1000 children-year (p < 0.001) through cART eras. Cumulative Nelson−Aalen hazards of developing ADM over a 20-year period were 3.73% in the Early-cART era, 3.07% in the Mid-cART era, and 0.32% in the Late-cART era (p = 0.013). This study demonstrates the IR of lymphoma in CLWH in RJ, Brazil, as well as the benefit of cART in reducing ADM and death occurrence in the Post-cART era.

Abstract
The objective of this study was to evaluate whether combination antiretroviral therapy (cART) has an effect on the clinical manifestations, radiological characteristics, and disease severity of human immunodeficiency virus (HIV)-associated Talaromyces marneffei infection. The clinical manifestations, chest computed tomography (CT) images, and disease severity were compared between 14 patients with culture-confirmed T. marneffei infections who received cART and 38 patients who did not receive cART. Clinical manifestations included high fever (>38°C), cough, shortness of breath, chills, and skin rash. Chest CT scans were evaluated for the presence of ground-glass opacities, consolidation, miliary nodules, nodules, masses, cavitation, pericardial effusion, pleural effusion, mediastinal lymphadenitis, and the distribution of parenchymal abnormalities. Disease severity was estimated by clinical manifestations and chest CT findings. Fever (>38°C), cough, shortness of breath, and chills were significantly less frequent in patients who received cART than in those who did not receive cART (P < 0.05). The frequencies of miliary nodules, mediastinal lymphadenitis, and the proportion of diffuse lesions were significantly lower in patients who received cART than in those who did not receive cART (P < 0.05). The disease severity was significantly decreased in patients who received cART compared with patients who did not receive cART (P < 0.001). T. marneffei-infected patients who received cART had fewer clinical manifestations and decreased disease severity compared with those who did not receive this treatment. The use of cART is associated with modified chest CT characteristics in HIV-associated T. marneffei infections.

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
RESUMO Este estudo investigou a relação entre suporte social, características sociodemográficas, clínicas e adesão ao Tratamento Antirretroviral (TARV) utilizando o questionário Social Support Inventory for People who are HIV Positive or Have AIDS. Para isso, foram avaliados 119 usuários HIV-positivos - dos quais 53,8% eram homens. Em relação à disponibilidade e satisfação, os valores médios foram de 3,37 (DP=1,00) para o suporte instrumental e 3,48 (DP=1,06) para o suporte emocional. Observaram-se diferenças significativas na disponibilidade e satisfação do suporte social com variáveis sociodemográficas e clínicas. Verificou-se que, quanto maior a disponibilidade e a satisfação com o suporte social, maior o OR para a adesão ao tratamento. O desenvolvimento de estratégias de apoio social pode contribuir positivamente para o controle da doença e melhor qualidade de vida dos usuários.

Abstract
The provision of ARVs is central to HIV/AIDS programs, because of its impact on the course of the disease and on quality of life. Although first-line treatments costs have declined, treatment-associated expenses are steeper each year. Sustainability is therefore an important variable for the success of treatment programs. A conceptual framework on sustainability of ARV provision was developed, followed by data collection instruments. The pilot study was undertaken in Brazil. Bolivia, Peru and Mozambique, were visited. Key informants were identified and interviewed. Investigation of sustainability related to ARV provision involved implementation and routinization events of provision schemes. Evidence of greater sustainability potential was observed in Peru, where provision is implemented and routinized by the National HIV/AIDS program and expenditures met by the government. In Mozambique, provision is dependent on donations and external aid, but the country displays a great effort to incorporate ARV provision and care in routine healthcare activities. Bolivia, in addition to external dependence on financing and management of drug supply, presents problems regarding implementation and routinization. The conceptual framework was useful in recognizing events that influence sustainable ARV provision in these countries.

Abstract
Since the introduction of highly active antiretroviral therapy (HAART) in 1996, there have been worldwide shifts in the causes of hospitalization for patients with HIV/AIDS. The aim of this study was to describe the characteristics of HIV/AIDS patient hospitalizations between 1997 and 2012. This cross-sectional study used a hospital database that centralizes records of admissions in 31 hospitals, both public and private, across 26 municipalities in the interior of São Paulo. In order to verify associations between the variables, we used the prevalence ratio (PR) and a 95% confidence interval. Among 9,797 adults and children, 10,696 admissions were registered, which was equal to 1.09 admissions per patient. Most (62%) of the patients were male, and the predominant age group was 21 and 50 years (63.5%). Mortality was higher among male patients from all age groups (PR= 1.42 [95% CI: 1.28-1.57]; p < 0.05). The main cause of hospitalization (54.5% of the total) was infectious disease, whether opportunistic or not. This was true, even in the post-HAART era. Furthermore, gender and age differences were noted in patient mortality rates.

Abstract
The HIV-1 epidemic in Brazil has spread towards the Northern country region, but little is known about HIV-1 subtypes and prevalence of HIV strains with resistance mutations to antiretrovirals in some of the Northern states. HIV-1 protease (PR) and reverse transcriptase (RT) sequences were obtained from 73 treatment-naive and -experienced subjects followed between 2013 and 2014 at a public health reference unit from Roraima, the northernmost Brazilian state. The most prevalent HIV-1 clade observed in the study population was the subtype B (91%), followed by subtype C (9%). Among 12 HIV-1 strains from treatment-naïve patients, only one had a transmitted drug resistance mutation for NNRTI. Among 59 treatment-experienced patients, 12 (20%) harbored HIV-1 strains with acquired drug resistance mutations (ADRM) that reduce the susceptibility to two classes of antiretroviral drugs (NRTI and NNRTI or NRTI and PI), and five (8%) harbored HIV-1 strains with ADRM that reduced susceptibility to only one class of antiretroviral drugs (NNRTI or PI). No patients harboring HIV strains with reduced susceptibility to all three classes of antiretroviral drugs were detected. A substantial fraction of treatment-experienced patients with (63%) and without (70%) ADRM had undetectable plasma viral loads (<40 copies/ml) at the time of sampling. Among treatment-experienced with plasma viral loads above 2,000 copies/ml, 44% displayed no ADRM. This data showed that the HIV-1 epidemic in Roraima displayed a much lower level of genetic diversity and a lower prevalence of ADRM than that described in other Brazilian states.

Abstract
The aim of this study is to establish the factors that influence the quality of life of people living with HIV/AIDS being treated at a specialized public service. The participants answered the questionnaire on sociodemographic conditions, issues related to HIV and daily habits. The quality of life was analyzed using the HIV/AIDS-targeted quality of life (HAT-QoL) instrument with 42 items divided into 9 fields: General Activity, Sexual Activity, Confidentiality Concerns, Health Concerns, Financial Concerns, HIV Awareness, Satisfaction with Life, Issues related to Medication and Trust in the Physician. Bivariate and multiple linear regressions were performed. Of the participants, 53.1% were women and had a mean age of 42 years. In analyzing the quality of life, the HAT-QoL domain with the lowest average was Financial Concerns (39.4), followed by Confidentiality Concerns (43.2), Sexual Activity (55.2) and Health Concerns (62. 88). There was an association between the variables: not being gainfully employed (p < 0.001), being mulatto or black (p = 0.045) and alcohol consumption (p = 0.041) with the worst quality of life scores. Inadequate socioeconomic and health conditions had a negative impact on the quality of life of people with HIV/AIDS.

Abstract
OBJECTIVE To investigate the prevalence of overweight, abdominal obesity and associated factors in people living with HIV/AIDS (PLWHA). METHOD Cross-sectional study with 270 PLWHA. A questionnaire was applied to investigate sociodemographic, clinical and lifestyle characteristics. Weight, height and waist circumference were measured. BMI ≥25 kg/m2 was considered overweight, while abdominal obesity referred to waist circumference ≥102 cm for men and ≥88 cm for women. The authors used multiple Poisson regression with 5% significance level. RESULTS The prevalence of overweight and abdominal obesity was 33.7% and 12.6%, respectively, referring to 37.9% of women and 5.7% of men (p<0.001). Overweight was associated with age of 40-49 years and ≥50 years, non-use of ARV therapy, and lower tertile of consumption of risk foods. Abdominal obesity was associated with: female gender, age of 40-49 years and ≥50 years, income greater than four times the minimum wage, and CD4+ lymphocyte count >350 cells/mm3. CONCLUSION There was a high prevalence of overweight and abdominal obesity associated with sociodemographic and clinical conditions, and consumption of risk foods. This scenario indicates the need for reorientation of the health care focus in this population.

Abstract
Background. The Pan-American Health Organization has called for reducing (1) human immunodeficiency virus (HIV) mother-to-child transmission (MTCT) to ≤0.30 infections/1000 live births (LB), (2) HIV MTCT risk to ≤2.0%, and (3) congenital syphilis (CS) incidence to ≤0.50/1000 LB in the Americas by 2015. Methods. Using published Brazilian data in a mathematical model, we simulated a cohort of pregnant women from antenatal care (ANC) through birth. We investigated 2 scenarios: "current access" (89.1% receive one ANC syphilis test and 41.1% receive 2; 81.7% receive one ANC HIV test and 18.9% receive birth testing; if diagnosed, 81.0% are treated for syphilis and 87.5% are treated for HIV) and "ideal access" (95% of women undergo 2 HIV and syphilis screenings; 95% receive appropriate treatment). We conducted univariate and multivariate sensitivity analyses on key inputs. Results. With current access, we projected 2.95 CS cases/1000 LB, 0.29 HIV infections/1000 LB, 7.1% HIV MTCT risk, and 11.11 intrauterine fetal demises (IUFD)/1000 pregnancies, with significant regional variation. With ideal access, we projected improved outcomes: 1.00 CS cases/1000 LB, 0.10 HIV infections/1000 LB, HIV MTCT risk of 2.4%, and 10.65 IUFD/1000 pregnancies. Increased testing drove the greatest improvements. Even with ideal access, only HIV infections/1000 LB met elimination goals. Achieving all targets required testing and treatment >95% and reductions in prevalence and incidence of HIV and syphilis. Conclusions. Increasing access to care and HIV and syphilis antenatal testing will substantially reduce HIV and syphilis MTCT in Brazil. In addition, regionally tailored interventions reducing syphilis incidence and prevalence and supporting HIV treatment adherence are necessary to completely meet elimination goals.

Abstract
Objective We examine the trend in causes of death among people living with AIDS in the city of São Paulo, Brazil, in the periods before and after the introduction of highly active antiretroviral therapy (HAART), and we investigate potential disparities across districts of residence. Methods Descriptive study of three periods: pre-HAART (1991–1996); early post-HAART (1997–1999); and late post-HAART (2000–2006). The data source was the São Paulo State STD/AIDS Program and São Paulo State Data Analysis Foundation. Causes of death were classified by the ICD-9 (1991–1995) and ICD-10 (1996–2006). We estimated age-adjusted mortality rates for leading underlying causes of death and described underlying and associated causes of death according to sociodemographic characteristics and area of residence. We used Pearson's chi-square test or Fisher's exact test to compare categorical variables. Areas of residence were categorized using a socioeconomic index. To analyze trends we apply generalized linear model with Poisson regression. Results We evaluated 32,808 AIDS-related deaths. Between the pre- and late post-HAART periods, the proportion of deaths whose underlying causes were non-AIDS-related diseases increased from 0.2% to 9.6% (p<0.001): from 0.01% to 1.67% (p<0.001) for cardiovascular diseases; 0.01% to 1.62% (p<0.001) for bacterial/unspecified pneumonia; and 0.03% to 1.46% (p<0.001) for non-AIDS-defining cancers. In the late post-HAART period, the most common associated causes of death were bacterial/unspecified pneumonia (35.94%), septicemia (33.46%), cardiovascular diseases (10.11%) and liver diseases (8.0%); and common underlying causes, besides AIDS disease, included non-AIDS-defining cancers in high-income areas, cardiovascular diseases in middle-income areas and assault in low-income areas. Conclusions The introduction of HAART has shifted the mortality profile away from AIDS-related conditions, suggesting changes in the pattern of morbidity, but heterogeneously according to area of residence. There is a need for public policies aimed at adapting health care services to address the new scenario.

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
Background The HIV-Brazil Cohort Study was established to analyze the effectiveness of combination antiretroviral therapy (cART) and the impact of this treatment on morbidity, quality of life (QOL) and mortality. The study design, patients’ profiles and characteristics of cART initiation between 2003 and 2010 were described. Methodology/Principal Findings Since 2003, the HIV-Brazil Cohort has been following HIV-infected adults receiving cART at 26 public health care facilities, using routine clinical care data and self-reported QOL questionnaires. When not otherwise available, data are obtained from national information systems. The main outcomes of interest are diseases related or unrelated to HIV; suppression of viral replication; adverse events; virological, clinical and immunological failures; changes in the cART; and mortality. For the 5,061 patients who started cART between 2003 and 2010, the median follow-up time was 4.1 years (IQR 2.2–5.9 years) with an 83.4% retention rate. Patient profiles were characterized by a predominance of men (male/female ratio 1.7∶1), with a mean age of 36.9 years (SD 9.9 years); 55.2% had been infected with HIV via heterosexual contact. The majority of patients (53.4%) initiated cART with a CD4+ T-cell count ≤200 cells/mm3. The medications most often used in the various treatment regimens were efavirenz (59.7%) and lopinavir/ritonavir (18.2%). The proportion of individuals achieving viral suppression within the first 12 months of cART use was 77.4% (95% CI 76.1–78.6). Nearly half (45.4%) of the patients presented HIV-related clinical manifestations after starting cART, and the AIDS mortality rate was 13.9 per 1,000 person-years. Conclusions/Significance Results from cART use in the daily practice of health services remain relatively unknown in low- and middle-income countries, and studies with the characteristics of the HIV-Brazil Cohort contribute to minimizing these shortcomings, given its scope and patient profile, which is similar to that of the AIDS epidemic in the country.

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
BACKGROUND The natural history of HIV infection has changed dramatically after the introduction of highly active antiretroviral therapy. Currently, opportunistic illnesses still represent a major cause of death and hospitalization in this population. In this study, we review the trends in opportunistic illnesses incidence rates and compare the results observed in high-income settings with that for low/middle-income settings, with special attention given to studies from Brazil. METHODS We systematically searched Pubmed, Web of Science, Lilacs and Google scholar for publications on HIV associated opportunistic illness. Studies reporting rates based on person-time for all opportunistic illnesses and/or the three opportunistic infections of interest, namely, Pneumocystis carinii pneumonia, cerebral toxoplasmosis, and Mycobacterium avium complex were included. RESULTS Significant reductions in the incidence rates were demonstrated for opportunistic illnesses overall and also for the specific opportunistic infections included in the present study, both in high and low/middle-income settings. Out of the 37 studies included in the present review, almost 70% were from high-income settings. All the studies conducted in low/middle-income settings were single center studies and four were from Brazil. We found no study from Brazil reporting annual incidence rates of opportunistic illnesses. CONCLUSIONS Opportunistic illnesses remain an important public health problem. To better guide health policies in low/middle-income settings, multicenter cohort studies should be encouraged. Studies from Brazil are urgently needed to assess the current burden of opportunistic illnesses in our population and to support the planning of HIV/AIDS health care services organization.

Abstract
This study analyzed data from two consecutive retrospective cohort samples (1983 to 1998 and 1999 to 2002) of Brazilian children with AIDS (N = 1,758) through mother-to-child-transmission. Late-stage diagnosis (CDC category C) was investigated in relation to the following variables: year of birth, year of HIV diagnosis, and time periods related to changes in government treatment guidelines. Late-stage diagnosis occurred in 731 (41.6%) of cases and was more prevalent in infants under 12 months of age. The rate of late-stage diagnosis decreased from 48% to 36% between the two periods studied. We also observed a reduction in the proportion of late-stage diagnoses and the time lapse between HIV diagnosis and ART initiation. A significant association was found between timely diagnosis and having been born in recent years (OR = 0.62; p = 0.009) and year of HIV diagnosis (OR = 0.72; p = 0.002/OR = 0.62; p < 0.001). Infants under the age of 12 months were more likely to be diagnosed at a late stage than older children (OR = 1.70; p = 0.004). Despite advances, there is a need to improve the effectiveness of policies and programs focused on improving early diagnosis and management of HIV/AIDS.

Abstract
BACKGROUND There are inconsistencies in the determinants of adherence to antiretrovirals (ARVs) across settings as well as a lack of studies that take into consideration factors beyond the individual level. This makes it necessary to examine factors holistically in multiple settings and populations while taking into consideration the particularities of each context, in order to understand the patterns of ARV adherence. This research explored ARV adherence and individual, relational and environmental-structural factors. METHODS A cross-sectional survey was conducted from August 2008 through July 2009 among participants currently on ARVs recruited from 6 public health clinics, selected to maximize diversity in terms of caseload and location, representing the range of clinics within Rio de Janeiro city, Brazil. Multivariate logistic regression analysis was used to assess the association between our multilevel factors with ARV adherence among participants with complete cases (n = 632). RESULTS Eighty-four percent of respondents reported adherence to all of their ARV doses in the last 4 days. Of the socio-demographic variables, those who had one child were positively associated with adherence (AOR 2.29 CI [1.33-3.94]). On the relational level, those with high social support (AOR 2.85 CI [1.50-5.41]) were positively associated with adherence to ARVs. On the environmental-structural level, we found gender was significant with women negatively associated with adherence to ARVs (AOR 0.58 CI [0.38-0.88]) while those with a high asset index (AOR 2.47 CI [1.79-3.40]) were positively associated with adherence to ARVs. CONCLUSIONS This research highlights the importance of examining the multiple levels of influence on ARV adherence. Intervention research in lower and middle-income settings should address and evaluate the impact of attending to both gender and economic inequalities to improve ARV adherence, as well as relational areas such as the provision of social support.

Abstract
Latin America is the region with the third most AIDS-related cryptococcal meningitis infections globally. Highly active antiretroviral therapy (HAART) has reduced the number of infections; however, the number of deaths and the case-fatality rate continues to be unacceptable. In this review, we focus on the burden of AIDS-related cryptococcosis in Latin America and discuss potential strategies to reduce early mortality from Cryptococcus. In this review, we highlight the importance of: (1) earlier HIV diagnosis and HAART initiation with retention-in-care to avoid AIDS; (2) pre-HAART cryptococcal antigen (CRAG) screening with preemptive fluconazole treatment; (3) better diagnostics (e.g. CRAG testing); and (4) optimal treatment with aggressive management of intracranial pressure and induction therapy with antifungal combination. Implementation of these strategies can reduce cryptococcal-related deaths, improve care, and reduce healthcare costs.

Abstract
In Southernmost Brazil HIV-1 subtypes B, C, and CRF31_BC co-circulates and, since 1996 with the implementation of free access to highly active antiretroviral treatment (HAART), this epidemic is under a quite characteristic selective pressure. The profile of mutations and polymorphisms in the protease (PR) and reverse transcriptase (RT) genes of HIV-1 from untreated patients living in Porto Alegre, Southernmost Brazil were evaluated in order to identify the subtypes and circulating drug resistant genotypes. Blood samples from 99 HIV-1 positive drugs-naïve patients were collected from 2006 to 2007 in Porto Alegre, Brazil. HIV PR and RT genes were amplified, sequenced, and subtyped. The HIV-1 genotyping was performed by partial sequence analysis of the pol in the HIV Drug Resistance Database of Stanford University. Phylogenetic analyses allowed to classify the HIV samples according to their subtypes: B (26.2%), C (39.4%), F (1.1%), CRF31_CB (19.2%), and URF (14.1%). Eight (8.1%) samples showed primary resistance mutations according to the Calibrated Population Resistance tool based in the 2009 Surveillance Drug Resistance Mutation list. Two samples presented resistance mutations to PI, three NRTI and three NNRTI. There was no significant association between presence of resistant genotypes and subtypes, but resistance mutations seem to be less frequent in the subtype C. In addition, this study describes for the first time the mutational profile of CRF31_BC to PI, NRTI, and NNRTI. Genetic analyses of HIV-1 from naïve patients are a promising and important method for surveillance of HIV infection.

Abstract
This cross-sectional study aimed to compare growth, nutritional status and body composition outcomes between a group of 94 HIV-infected children and adolescents on antiretroviral therapy (ART) and 364 healthy controls, and to evaluate their association with clinical and lifestyle variables within the HIV-infected group. When compared with the control group, HIV patients had higher risk of stunting (odds ratio [OR] 5.33, 95% confidence interval [CI]: 2.83-10.04) and thinness (OR 4.7, 95% CI: 2.44-9.06), higher waist-to-hip ratios (medians 0.89 versus 0.82 for boys and 0.90 versus 0.77 for girls, P < 0.001), and lower prevalence of overweight or obesity (OR 0.33, 95% CI: 0.14-0.78). Protease inhibitor usage was associated with thinness (OR 3.51, 95% CI 1.07-11.44) and lipoatrophy (OR 3.5, 95% CI 1.37-8.95). HIV-infected children on ART showed significant nutritional status and body composition abnormalities, consistent with the severity of vertical HIV infection and the consequences of prolonged ART.

Abstract
AIDS-related mortality has been significantly reduced in areas that systematically adopted highly active antiretroviral therapy (HAART). In Brazil, despite advances in control policy, there is still a lack of evidence about trends in children on causes of death related or not related to HIV/AIDS. We evaluate temporal trends in mortality due to non-HIV-related causes of death in relation to HIV/AIDS-related conditions among children with and without HIV infection. This nationwide study included all deaths in children reported from 1999 to 2007. Mortality odds ratios (MOR) and rates were calculated to assess time trends of death in children with or without HIV/AIDS. These data were analyzed by calendar year, as obtained from official national database. A total of 680,763 deaths occurred in Brazilian children under 13 years of age; of these, 2191 (0.32%) had causes related to HIV/AIDS listed on the death certificate. The mortality rate from HIV/AIDS-related causes in Brazilian children ranged from 0.72 per 100,000 children in 1999 to 0.40 per 100,000 children in 2007, while for selected nonrelated causes the rate of death among HIV-infected children was stable at 0.08 per 100,000 Brazilian children. In children with HIV/AIDS, the MOR of having selected conditions unrelated to HIV/AIDS as a cause of death in 2007 (compared to 1999) was 1.85 (95% confidence interval [CI] = 1.11-3.08, p = 0.02), but without a significant temporal trend (p = 0.413) through the analyzed period. In Brazil, deaths related to HIV/AIDS mortality in children significantly decreased, while the unrelated causes in HIV-infected children maintained a stable trend. These data reinforce the success of national public health policies and the need to offer comprehensive care to children with HIV/AIDS.

Abstract
The objective of this study is to characterize survival in children with AIDS diagnosed in Brazil between 1999-2002, compared with the first national study (1983-1998). This national retrospective cohort study examined a representative sample of Brazilian children exposed to HIV from mother-to-child transmission and followed through 2007. The survival probability after 60 months was analyzed by sex, year of birth and death, clinical classification, use of antiretroviral therapy (ART) and prophylaxis for opportunistic diseases. 920 children were included. The survival probability increased: comparing cases diagnosed before 1988 with those diagnosed from 2001-2002 it increased by 3.5-fold (from 25% to 86.3%). Use of ART, initial clinical classification, and final classification were significant (p < 0.001) predictors of survival. Issues regarding quality of records and care were identified. The results point to the success of the Brazilian policy of providing ART. The improvement of clinical status contributes to quality of life, while indicating challenges, particularly practices to improve long-term care.

Abstract
BACKGROUND The objective of this study was to analyze regional trends over time of acquired immunodeficiency syndrome (AIDS) cases and deaths in Brazilian children, before and after implementation of free access to highly active antiretroviral treatment (HAART). METHODS We performed a nation-wide study with an ecologic design and a time-series analysis of AIDS incidence and mortality rates in children (0-12 years of age), using polynomial regression models. Data were obtained from official national databases on age group, residence region, and year of AIDS diagnosis and death (1984-2008). RESULTS Between 1984 and 2008, 14,314 (2.7%) AIDS cases and 5041 deaths (2.3% of all AIDS-related deaths) were reported in Brazilian children. Incidence after 1996 was reduced by 23%, as compared with the pre-HAART era. The mortality rate observed in the HAART era was reduced by 63.6%. There was a significant reduction in the incidence in the Southeast and Central-West regions (P < 0.001), but the less industrialized North region showed an increase in the pre-HAART era (P < 0.001), and the Northeast region showed a stabilization trend (P < 0.001). In the South region, the incidence of AIDS increased in the 0 to 4 years subgroup. A reduction of AIDS mortality in the Southeast (P < 0.001), South, and Central-West regions (P < 0.001) was seen, but the Northeast and North regions maintained an increasing mortality trend (P < 0.001). CONCLUSIONS Despite the overall reduction in AIDS-related cases and deaths among children in Brazil since HAART, marked regional differences continue to exist. These reflect structural factors, different transmission dynamics, and operational issues. There is a need for improving the health service network with special emphasis on the less developed regions.

Abstract
We present a systematic review of historical, political, and epidemiologic aspects of AIDS in Brazilian children. Over 25 years, Brazil has developed different strategies to control AIDS in children. Three revisions of criteria for defining AIDS cases in children and nine national guidelines on antiretroviral therapy administration for management of HIV infection were published. These guidelines represent important progress, including aspects of HIV/AIDS surveillance, antiretroviral treatment, opportunistic conditions, prophylaxis, and laboratory testing. Brazil has significantly expanded access to free therapy with different classes of antiretroviral drugs. Initially focusing on treatment for HIV and opportunistic conditions, the scope of treatment guidelines gradually expanded to comprehensive health care for children and adolescents. From 1996 to 2008, the number of AIDS cases and deaths in children has been reduced by 67% and 65%, respectively, as a result of different strategies to prevent mother-to-child transmission of HIV and highly active antiretroviral therapy administration to infected children. Improved morbidity, mortality, and survival of Brazilian children with AIDS demonstrate clear benefits of adopting a policy of free and universal access to antiretroviral drugs associated with comprehensive care. However, important issues remain to be resolved, mainly concerning social, operational, and regional inequalities in coverage and quality of care, and epidemiological surveillance in different regions of the country. This broad review shows that the overall situation of pediatric AIDS in Brazil represents an incomplete process of epidemiologic and demographic transition, with the coexistence of old and new clinical and epidemiologic challenges.

Abstract
The aim of this study was to describe the effect of non-adherence on the main laboratory outcomes, TCD4+ lymphocyte count and viral load, routinely used to monitor patients initiating treatment according to three different approaches to measure adherence to antiretroviral therapy. Among 288 participants, 22.9%, 31.9% and 74.3% were considered non-adherent, according to medical charts, self-report and pharmacy records, respectively. Depending on the adherence measures used, the average gain in TCD4+ lymphocyte count ranged from 142.4 to 195.4 cells/mm3 among adherent patients, and from 58.5 to 99.8 lymphocytes TCD4+/mm3 among those non-adherent. The average reduction on viral load ranged from 4.25 to 4.62 log copies/mL among the adherent patients, and from 1.99 to 4.07 log among those non-adherent. Monitoring antiretroviral adherence should be considered a priority in these public AIDS referral centers in order to identify patients at high risk of developing virologic failure. Early interventions are necessary in order to maintain the initial therapeutic regimens for longer periods.

Abstract
The aim of this study was to evaluate strategies by the Brazilian Ministry of Health to expand the municipal response to AIDS. Cities "included" and "not included" in Federal strategies for "municipalization" of the response were compared according to the response profile and trends in the epidemic. Multinomial logistic regression was used, among other statistical procedures. Municipalities included from 1994 to 1998 showed higher chances of providing HIV diagnostic testing [OR = 15.0; 95%CI: 5.6-40.1], of having AIDS services [OR = 18.4; 95%CI: 8.4-40.5], and reducing cases involving heterosexual [OR = 3.1; 95%CI: 1.4-7.3], homosexual/bisexual [OR = 3.0; 95%CI: 1.4-6.2], and IDU transmission [OR = 6.6; 95%CI: 2.9-14.9] as compared to those "included in 2003" and "not included". There were no associations between the included Municipalities, greater coverage in prevention, the reduction in cases due to vertical transmission or blood transfusion, or mortality rates. Municipalities with a more structured response were associated with better results. The findings suggest that the municipalization policy contributed to improvement in the local response to AIDS.

HIV prevalence among female sex workers, drug users and men who have sex with men in Brazil: a systematic review and meta-analysis. BMC Public Health 2010; 10:317.

Abstract
Background The Brazilian response towards AIDS epidemic is well known, but the absence of a systematic review of vulnerable populations ─ men who have sex with men (MSM), female sex workers (FSW), and drug users (DU) remains a main gap in the available literature. Our goal was to conduct a systematic review and meta-analysis of studies assessing HIV prevalence among MSM, FSW and DU, calculating a combined pooled prevalence and summarizing factors associated the pooled prevalence for each group. Methods Nine electronic databases (MEDLINE via PubMed, EMBASE, Cochrane CENTRAL, AIDSLINE, AMED, CINAHL, TOXNET, SciELO, and ISI-Web of Science) were searched for peer-reviewed papers published in English, French, Spanish or Portuguese, from 1999 to 2009. To be included in the review, studies had to measure HIV prevalence and/or incidence as the primary outcome among at least one specific population under analysis. Results The studies targeting the three populations analyzed mostly young participants aged 30 years or less. Among FSW, eight studies were selected (3,625 participants), consistently identifying higher condom use with sexual clients than with occasional and stable partners. The combined HIV prevalence for FSW was 6.2 (95% CI: 4.4-8.3). Ten studies targeting MSM were identified (6,475 participants). Unprotected anal intercourse was commonly reported on those studies, but with great variability according to the nature of the relationship - stable vs. occasional sex partners - and sexual practice - receptive vs. insertive anal sex. Pooled HIV prevalence for MSM was 13.6 (95% CI: 8.2-20.2). Twenty nine studies targeting DU were identified (13,063 participants). Those studies consistently identified injection drug use and syringe/needle sharing as key predictors of HIV-infection, as well as engagement in sex work and male-to-male sex. The combined HIV prevalence across studies targeting DU was 23.1 (95% CI: 16.7-30.2). Conclusions FSW, MSM and DU from Brazil have a much risk of acquiring HIV infection compared to the general population, among which HIV prevalence has been relatively low (~0.6%). Those vulnerable populations should be targeted by focused prevention strategies that provide accurate information, counseling and testing, as well as concrete means to foster behavior change (e.g. access to condoms, drug abuse treatment, and clean syringes in the case of active injecting drug users), tailored to gender and culture-specific needs. Programs that provide these services need to be implemented on public health services throughout the country, in order to decrease the vulnerability of those populations to HIV infection.

Abstract
This retrospective cohort study examined a nationally representative sample of 945 Brazilian children (ages 0-12 years) diagnosed with AIDS in 1999 to 2002 and followed through 2007. The probability of survival to 60 months was 86.3% (95% CI, 84.1%-88.5%). This compares with 52.8% (95% CI, 41.9%-60.8%) in a study of cases diagnosed in 1983 to 1998. These results demonstrate substantial improvement in survival for children with AIDS in Brazil.

Abstract
Cross-sectional study analyzed as case-control to identify risk factors for non-adherence to antiretroviral therapy. We studied 412 out-clinics HIV infected subjects of three public hospitals of Recife, Pernambuco. The objective was to examine the association between non-adherence to the antiretroviral therapy and biological, social-behavior and demographics and economic factors, factors related to the disease and/or treatment, factors related to life habits and depression symptoms. Variables significantly associated with non-adherence to antiretroviral therapy were: time elapsed since HIV diagnosis (p = 0.002), daily dose (p = 0.046), use of alcohol (p = 0.030) and past drug use (p = 0.048), and borderline p-values were found for educational level (p = 0.093) and family monthly income (p = 0.08). In the multivariable analysis, the factors that remained in the final model were family monthly income, time period with HIV infection and use of alcohol. No association was observed between non-adherence to antiretroviral therapy and gender, age, sexual orientation, marital status, educational level and place of residence. Based on our results and the local situation we suggest: assessment of social needs; training of partners and/or families on supporting adherence, creation of 'adherence groups' to motivate and to reassure patients on the benefits of treatment; counseling and/or psychotherapy for alcohol drinkers.

Abstract
BACKGROUND This article provides a summary of the current status of the HIV/AIDS epidemic in Latin America, as well as an outline of the diverse responses to it. METHODS A search of international databases (Pubmed and ISI-Web of Science), regional databases (Scielo and Lilacs), regional and national documents and UNAIDS reports. Data are presented according to subregion. RESULTS In Mexico HIV remains concentrated among urban men who have sex with men (MSM), and has been growing among injecting drug users (IDU) and in rural areas in relation to migration. An increasing proportion of women among those affected is observed in all countries in Central America, the most affected region, as well as increasing the impact on other vulnerable groups, such as indigenous populations. The Andean Countries have urban epidemics concentrated among MSM. In Peru, non-traditional vulnerable populations were identified. In the Southern Cone heterosexual transmission became more relevant, probably in connection with IDU epidemics and is increasingly affecting lower income groups. Incidence rates have been declining since 2002 in Brazil, the first country to guarantee free, universal access to antiretrovirals, where one-third of drug-naïve patients are still initiating treatment at an advanced stage. Generally, access to treatment has improved as a result of support from the Global Fund and other initiatives, but there are concerns regarding coverage, equity and sustainability. CONCLUSIONS HIV is still concentrated among MSM in Latin America. Non-traditional vulnerable groups such as migrants and lower income populations, usually considered part of the general population, deserve attention. Programmes confronting sexual exclusion are still needed. Access to treatment has improved over time, but inequalities persist.

Abstract
Since the start of the HIV epidemic we have witnessed significant advances in our understanding of the impact of HIV disease worldwide. Furthermore, breakthroughs in treatment and the rapid expansion of HIV care and treatment programmes in heavily impacted countries over the past 5 years are potentially critical assets in a comprehensive approach to controlling the continued spread of HIV globally. A strategic approach to controlling the epidemic requires continued and comparable expansion and integration of care, treatment and prevention programmes. As every new infection involves transmission, whether vertically or horizontally, from a person living with HIV/AIDS (PLWHA), the integration of HIV prevention into HIV care settings has the potential to prevent thousands of new infections, as well as to improve the lives of PLWHA. In this paper, we highlight how to better utilize opportunities created by the antiretroviral roll-out to achieve more effective prevention, particularly in sub-Saharan Africa. We offer specific recommendations for action in the domains of healthcare policy and practice in order better to utilize the advances in HIV treatment to advance HIV prevention.

Abstract
The Brazilian AIDS epidemic is undergoing important changes in its third decade. The present article reviews some central findings: the proportional reduction in cases related to injection drug use; the stability, in recent years, of new cases in the male homosexual/bisexual population; and the relative and absolute increment in heterosexual transmission, even though the estimates of incident rates still point to the first two categories mentioned as those most affected by the epidemic. Still should be detached the persistent increase in incidence rates among women and its stability in the younger age groups, probably the result of behavior changes (such as the consistent use among youth of condoms in sexual relations with casual partners and a reduction in cases related to injection drug use). It is well-know that HIV prevalence in the general population has stabilized at less than 1%, which characterizes Brazil as one of the countries with a concentrated epidemic. The article also emphasizes the growth of AIDS morbidity-mortality in the less favored socioeconomic strata and in women, and the stability of the mortality rate among men.
