Aging with HIV in Latin America and the Caribbean: a Systematic Review.
Ontology highlight
ABSTRACT: Purpose of review
With the establishment of antiretroviral treatment (ART) programs in low- and middle-income countries, people with HIV (PWH) in Latin America and the Caribbean (LAC) are living longer, subsequently developing chronic non-communicable diseases (NCDs). Few studies focus on the impact of aging among older LAC PWH. This systematic review aims to fill this information gap and understand the burden of aging with HIV in LAC. We identified peer-reviewed literature published in English, Spanish, or Portuguese from several databases to assess currently available evidence on the burden of aging with HIV in LAC and selected six common NCDs found in older PWH (cardiovascular disease [CVD], bone and musculoskeletal [MSK] disorders, cancer, renal disease, neurocognitive impairment [NCI], and depression).Recent findings
Of the 5942 publications reviewed, only 53 articles were found with populations 40 years and older or age-related findings (27 CVD, 13 NCI or depression, 6 MSK disorders, 4 renal disease, 3 cancer). Most (79%) publications were from Brazil with few longitudinal studies on aging with HIV. Prevalence of illnesses such as CVD, NCI, depression, or osteoporosis varied widely depending on the screening instrument utilized and geographic population surveyed. Age was a significant predictor of comorbidity in nearly all studies. Our results demonstrate the need for longitudinal studies and validated screening instruments appropriate for use among PWH in LAC. Understanding the mechanisms behind aging in HIV and the roles of sociocultural factors and genetic diversity specific to LAC is needed to appropriately manage chronic comorbidities as PWH age.

Project description:IntroductionOptimal adherence to antiretroviral therapy is closely related with suppression of the HIV viral load in plasma, slowing disease progression and decreasing HIV transmission rates. Despite its importance, the estimated proportion of people living with HIV in Latin America and the Caribbean with optimal adherence has not yet been reported in a meta-analysis. Moreover, little is known of the factors leading to poor adherence which may be setting-specific. We present a pooled estimate of adherence to antiretroviral therapy (ART) of people living with HIV in Latin America and Caribbean, report the methods used to measure adherence and describe the factors associated with poor adherence among the selected studies.MethodsWe electronically searched published studies up to July 2016 on the PubMed, Web of Science and Virtual Health Library (Latin America and the Caribbean Regional Portal); considering the following databases: MEDLINE, LILACS, PAHO and IBECS. Two independent reviewers selected and extracted data on ART adherence and study characteristics. Pooled estimate of adherence was derived using a random-effects model. Risk of bias in individual studies was assessed independently by two investigators using the Risk of Bias Assessment tool for Non-randomized Studies (RoBANS).Results and discussionThe meta-analysis included 53 studies published between 2005 and 2016, which analysed 22,603 people living with HIV in 25 Latin America and Caribbean countries. Overall adherence in Latin America and Caribbean was 70% (95% CI: 63-76; I2 = 98%), similar to levels identified by studies conducted in high-income regions. Self-report was the most frequently used method to measure adherence. Subgroup analysis showed that adherence was higher for the shortest recall time frame used, as well as in countries with lower income level, Gross National Income (GNI) per capita and Human Development Index (HDI). Studies reported diverse adherence barriers, such as alcohol and substance misuse, depression, unemployment and pill burden.ConclusionsOur study suggests that adherence to ART in Latin America and Caribbean may be below the sufficient levels required for a successful long-term viral load suppression.

Project description:BackgroundHIV transmitted drug resistance (TDR) remains at moderate level in Latin America and the Caribbean (LAC). However, different epidemiologic scenarios could influence national and sub-regional TDR levels and trends.Methods and findingsWe performed a systematic review of currently available publications on TDR in antiretroviral treatment-naïve adults in LAC. Ninety-eight studies published between January 2000 and June 2015 were included according to critical appraisal criteria and classified by sub-region: Brazil (50), Mesoamerica (17), Southern Cone (16), Andean (8) and Caribbean (7). From these, 81 studies encompassing 11,441 individuals with data on DR mutation frequency were included in a meta-analysis. Overall TDR prevalence in LAC was 7.7% (95% CI: 7.2%-8.2%). An increasing trend was observed for overall TDR when comparing 2000-2005 (6.0%) and 2006-2015 (8.2%) (p<0.0001), which was associated with significant NNRTI TDR increase (p<0.0001). NRTI TDR decreased (4.5% vs. 2.3%, p<0.0001). NNRTI TDR increase was associated mainly with K101E, K103N and G190A. NRTI TDR decrease was associated mainly with M184V, K70R and T215Y. All sub-regions reached moderate overall TDR levels. The rapid increase in TDR to all antiretroviral classes in the Caribbean is notable, as well as the significant increase in NNRTI TDR reaching moderate levels in the Southern Cone. NRTI TDR was dominant in 2000-2005, mainly in the Caribbean, Mesoamerica and Brazil. This dominance was lost in 2006-2015 in all sub-regions, with the Southern Cone and the Caribbean switching to NNRTI dominance. PI TDR remained mostly constant with a significant increase only observed in the Caribbean.ConclusionsGiven the high conceptual and methodological heterogeneity of HIV TDR studies, implementation of surveys with standardized methodology and national representativeness is warranted to generate reliable to inform public health policies. The observed increasing trend in NNRTI TDR supports the need to strengthen TDR surveillance and programme monitoring and evaluation in LAC.

Project description:BackgroundCardiovascular prognostic models guide treatment allocation and support clinical decisions. Whether there are valid models for Latin American and Caribbean (LAC) populations is unknown.ObjectiveThis study sought to identify and critically appraise cardiovascular prognostic models developed, tested, or recalibrated in LAC populations.MethodsThe systematic review followed the CHARMS (CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies) framework (PROSPERO [International Prospective Register of Systemic Reviews]: CRD42018096553). Reports were included if they followed a prospective design and presented a multivariable prognostic model; reports were excluded if they studied symptomatic individuals or patients. The following search engines were used: EMBASE, MEDLINE, Scopus, SciELO, and LILACS. Risk of bias assessment was conducted with PROBAST (Prediction model Risk Of Bias ASsessment Tool). No quantitative summary was conducted due to large heterogeneity.ResultsFrom 2,506 search results, 8 studies (N = 130,482 participants) were included for qualitative synthesis. We could not identify any cardiovascular prognostic model developed for LAC populations; reviewed reports evaluated available models or conducted a recalibration analysis. Only 1 study included a Caribbean population (Puerto Rico); 3 studies were retrieved from Chile; 2 from Argentina, Brazil, Colombia, and Uruguay; and 1 from Mexico. Four studies included population-based samples, and the other 4 included people affiliated to a health facility (e.g., prevention clinics). Most studied participants were older than 50 years, and there were more women in 5 reports. The Framingham model was assessed 6 times, and the American College of Cardiology/American Heart Association pooled equation was assessed twice. Across the prognostic models assessed, calibration varied widely from one population to another, showing great overestimation particularly in some subgroups (e.g., highest risk). Discrimination (e.g., C-statistic) was acceptable for most models; for Framingham it ranged from 0.66 to 0.76. The American College of Cardiology/American Heart Association pooled equation showed the best discrimination (0.78). That there were few outcome events was the most important methodological limitation of the identified studies.ConclusionsNo cardiovascular prognostic models have been developed in LAC, hampering key evidence to inform public health and clinical practice. Validation studies need to improve methodological issues.

Project description:ObjectiveTo estimate the pooled prevalence of multimorbidity (≥2 non-communicable diseases in the same individual) among adults of the general population of Latin American and the Caribbean (LAC).DesignSystematic review and meta-analysis.Data sourcesMEDLINE, Embase, Global Health, Scopus and LILACS up to 1 July 2020.Eligibility criteria for selecting studiesThe outcome was the prevalence of multimorbidity. Reports were selected whether they enrolled adult individuals (age ≥18 years) from the general population.Data extraction and synthesisReviewers extracted relevant data and assessed risk of bias independently. A random-effects meta-analysis was conducted to report pooled prevalence estimates of multimorbidity; pooled estimates by pre-specified subgroups (eg, national studies) were also pursued.ResultsFrom 5830 results, we selected 28 reports, mostly from Brazil and 16 were based on a nationally representative sample. From the 28 selected reports, 26 were further included in the meta-analysis revealing a pooled multimorbidity prevalence of 43% (95% CI: 35% to 51%; I2: 99.9%). When only reports with a nationally representative sample were combined, the pooled prevalence was 37% (95% CI: 27% to 47%; I2: 99.9%). When the ascertainment of multimorbidity was based on self-reports alone, the pooled prevalence was 40% (95% CI: 31% to 48%; I2: 99.9%); this raised to 52% (95% CI: 33% to 70%; I2: 99.9%) for reports including self-reported and objective diagnosis.ConclusionsOur results complement and advance those from global efforts by incorporating much more reports from LAC. We revealed a larger presence of multimorbidity in LAC than previously reported.Prospero registration numberCRD42020196177.

Project description:BACKGROUND:Countries in Latin America and the Caribbean (LAC) have experienced a rapid increase in their proportion of older people. This region is marked by a high prevalence of chronic diseases and disabilities among aging adults. Frailty appears in the context of LAC negatively affecting quality of life among many older people. AIM:To investigate the prevalence of frailty among community-dwelling older people in LAC through a systematic review and meta-analysis. METHODS:A literature search was performed in indexed databases and in the grey literature. Studies investigating the prevalence of frailty with representative samples of community-dwelling older people in Latin America and the Caribbean were retrieved. Independent investigators carried out the study selection process and the data extraction. A meta-analysis and meta-regression were performed using STATA 11 software. The systematic review was registered at the International Prospective Register of Systematic Reviews under the number CRD42014015203. RESULTS:A total of 29 studies and 43,083 individuals were included in the systematic review. The prevalence of frailty was 19.6% (95% CI: 15.4-24.3%) in the investigated region, with a range of 7.7% to 42.6% in the studies reviewed. The year of data collection influenced the heterogeneity between the studies. CONCLUSION:Frailty is very common among older people in LAC. As a result, countries in the region need to adapt their health and social care systems to demands of an older population.

Project description:BackgroundVaricella is typically mild and self-limiting, but can be associated with complications and even death. The limited data available on varicella in Latin America and the Caribbean (LAC) indicate substantial burden in countries where varicella vaccine is not part of publicly funded childhood national immunization programs.MethodsA systematic literature review of published studies was complemented by "gray" literature on varicella incidence, complications, mortality, and economic consequences, in the absence and presence of universal varicella vaccination (UVV) in LAC.ResultsSeroprevalence data indicate that varicella is usually a disease of childhood in LAC. Varicella incidence rates, while unreliable in the absence of mandatory reporting, show a trend to increased incidence due to greater urbanization and population density. The introduction of UVV in national immunization programs has led to significant reductions in varicella incidence in these areas.ConclusionsVaricella continues to pose a substantial healthcare burden in LAC. The future introduction of UVV in additional countries is predicted to provide substantial reductions in cases, with important economic benefits. For countries that have already implemented UVV, the challenge is to maintain high rates of coverage and, where relevant, consider inclusion of a second dose to reduce breakthrough cases. Given the significant proportion of the region now implementing UVV, a regional recommendation in order to prevent any potential for age-shifts in varicella infection might be considered.

Project description:ObjectiveInfluenza causes severe morbidity and mortality. This systematic review aimed to assess the incidence, etiology, and resource usage for influenza in Latin America and the Caribbean.DesignMeta-analytic systematic review. Arcsine transformations and DerSimonian Laird random effects model were used for meta-analyses.SettingA literature search from 1980 to 2008 in MEDLINE, Cochrane Library, EMBASE, LILACS, Ministries of Health, PAHO, proceedings, reference lists, and consulting experts.SampleWe identified 1092 references, of which 31 were finally included, in addition to influenza surveillance reports. We also used information from the 10 reports from the collaborative group for epidemiological surveillance of influenza and other respiratory virus (GROG), and information retrieved from the WHO global flu database FLUNET.Main outcome measuresIncidence, percentage of influenza specimens out of the total received by influenza centers and resource-use outcomes.ResultsA total of 483 130 specimens of patients with influenza were analyzed. Meta-analysis showed an annual rate of 36 080 (95%CI 28 550 43 610) influenza-like illness per 100 000 persons-years. The percentage of influenza out of total specimens received by influenza centers ranged between 4.66% and 15.42%, with type A the most prevalent, and A subtype H3 predominating. The mean length of stay at hospital due to influenza ranged between 5.8 12.9 days, total workdays lost due to influenza-like illnesses were 17 150 days, and the mean direct cost of hospitalization was US$575 per laboratory-confirmed influenza case.ConclusionsOur data show that seasonal influenza imposes a high morbidity and economic burden to the region. However, the vaccine-uptake rate has been low in this region. Population-based cohort studies are required to improve the knowledge about incidence and resource utilization, which would inform healthcare authorities for decision making.

Project description:Studies show that a large number of women around the world have experienced situations of abuse, disrespect, abuse, and neglect during childbirth and/or abortion. This violence is a serious violation of the rights of women, especially because it is a period in which the woman is more physiologically, socially, and psychologically vulnerable. Although this type of violence is known, there is still no international consensus on the definition of such violence and its prevalence is not known. In this sense, this systematic review aims (1) to find quantitative data about abuse and disrespect in obstetric care (delivery and/or abortion) in Latin America and the Caribbean to estimate the average prevalence of this type of abuse and (2) to identify interventions-including programs, laws, and regulations-which have been implemented to prevent or respond to abuse and disrespect in childbirth process and abortion situation, evaluating its effectiveness on a global scale.For this, we will use a refined and pre-established strategy to search databases such as PubMed, Embase, LILACS, and Scielo, and the studies found will pass through a selection process to complete the screening stage.Data will be extracted using standardized forms with the following information: scope of study, sample characteristics, objectives, design, data collection, methods of analysis, data source, and results. Considering the heterogeneity of the definitions of abuse, disrespect, and mistreatment of women in labor or abortion, it may not be possible to carry out the meta-analysis of the frequency of events reported in the included articles. Events reported by the original articles will be classified according to a typology of abuse, disrespect, and maltreatment in the labor or abortion process described by Bohren et al. (PLoS Med, 2015).PROSPERO CRD42016038651.

Project description:We aimed to study time trends and levels of mean total cholesterol and lipid fractions, and dyslipidaemias prevalence in Latin America and the Caribbean (LAC). Systematic-review and meta-analysis of population-based studies in which lipid (total cholesterol [TC; 86 studies; 168,553 people], HDL-Cholesterol [HDL-C; 84 studies; 121,282 people], LDL-Cholesterol [LDL-C; 61 studies; 86,854 people], and triglycerides [TG; 84 studies; 121,009 people]) levels and prevalences were laboratory-based. We used Scopus, LILACS, Embase, Medline and Global Health; studies were from 1964 to 2016. Pooled means and prevalences were estimated for lipid biomarkers from ≥2005. The pooled means (mg/dl) were 193 for TC, 120 for LDL-C, 47 for HDL-C, and 139 for TG; no strong trends. The pooled prevalence estimates were 21% for high TC, 20% for high LDL-C, 48% for low HDL-C, and 21% for high TG; no strong trends. These results may help strengthen programs for dyslipidaemias prevention/management in LAC.

Project description:ObjectivesSummarize hepatitis C virus (HCV) prevalence in injecting (IDU) and non-injecting drug users (NIDU), men who have sex with men (MSM), sex workers, and prison inmates in Latin America and the Caribbean (LAC).MethodsSystematic review on HCV prevalence in sub-populations in LAC. Databases searched from 1-1-2000 to 10-30-2013.Inclusion criteriaprevalence studies in sub-populations in LAC. HCV-antibody was marker for prevalence of current/past HCV infection and HCV-RNA for prevalence of HCV current infection.ResultsIDU HCV current/past infection presented highest prevalence, from 1.7 % in Colombia to over 95 % in Ciudad Juarez and Tijuana, Mexico and pooled regional anti-HCV prevalence was 49 % (CI 95 % 22.6-76.3 %). NIDU, MSM and sex workers anti-HCV prevalence was below 10 %, and pooled regional prevalence of 4 % (CI 95 % 2.6-4.5 %), 3 % (CI 95 % 1.7-4.5 %) and 2 % (CI 95 % 1.0-3.4 %), respectively. Prison inmates presented higher values, but prevalence decreased over the 15-year time span (p < 0.001). Current HCV infection from three countries showed prevalence under 10 % in prison inmates and 1-46 % among drug users.ConclusionsDisease burden is high and surveillance, prevention and treatment should target these groups in LAC.
