Non-adherence among patients initiating antiretroviral therapy: a challenge for health professionals in Brazil.

Objective:To assess the incidence, magnitude and factors associated with the first episode of non-adherence for 12 months after the first antiretroviral prescription. Design:A prospective study of HIV-infected patients receiving their first antiretroviral prescription in public referral centers, Belo Horizonte, Brazil. Baseline assessment occurred at the moment of the first prescription and follow-up visits at the first, fourth and seventh month, from May 2001 to May 2003. Methods:Non-adherence was self-reported and defined as the intake of less than 95% of the prescribed doses for 3 days before the follow-up interviews. Cumulative and person-time incidence were estimated and Coxs proportional model was used to assess the relative hazard (RH) of non-adherence with 95% confidence interval for both univariate and multivariate analysis. Results:Among 306 patients, the cumulative incidence of non-adherence was 36.9% (incidence rate 0.21/100 person-days). Multivariate analysis (P < 0.05) showed that unemployment (RH = 2.17), alcohol use (RH = 2.27), self-report of three or more adverse reactions (RH = 1.64), number of pills per day (RH = 2.04), switch in antiretroviral regimen (RH = 2.72), and a longer time between the HIV test result and the first antiretroviral prescription (RH = 2.27) were associated with an increased risk of non-adherence, whereas the use of more than one health service indicated a negative association (RH = 0.54). Conclusion:The current analysis has pointed out the importance of clinical and health service characteristics as potential indicators of non-adherence after initiating therapy. Early assessment and intervention strategies should be priorities in these AIDS public referral centres. Feasible and reliable indicators for the routine monitoring of adherence should be incorporated in clinical practice.

Association between socioeconomic factors and infant deaths due to diarrhea, pneumonia, and malnutrition in a metropolitan area of Southeast Brazil: a case-control study

A population-based case-control study was carried out to identify determinant factors for post-neonatal infant deaths due to diarrhea, pneumonia, and malnutrition in Greater Metropolitan Belo Horizonte, Southeast Brazil. From May 1, 1991, to April 30, 1992, 511 post-neonatal deaths due to diarrhea, pneumonia, and malnutrition were selected after investigation of medical records to validate cause of death. Of this total, 396 deaths were compared to a neighborhood control group, matched for age. The study was carried out in a low-income area with a high proportion of families living in shantytowns. The article discusses the methodology and selected socioeconomic factors. Logistic regression analysis indicated that number of household appliances, mothers and fathers education, and mothers marital and work status were significantly associated with risk of infant death, i.e., they were determinants of infant deaths due to avoidable causes.

Temporal trends in AIDS-associated opportunistic infections in Brazil, 1980-1999

Trends in annual incidence of reported AIDS-associated opportunistic infections (OI/100 adults > 12 years old) among AIDS cases were estimated at the national level in Brazil from 1980 through May 1999. The analysis included chi-square and linear regression modeling. The opportunistic infections included: candidiasis (CD), tuberculosis (TB), Pneumocystis carinii pneumonia (PCP), neurotoxoplasmosis (NT), Kaposi sarcoma (KS), cryptococcal meningitis (CM), and protozoa infections (PI). The overall cumulative incidence rates/100 reported AIDS cases were: CD = 59, TB = 26, PCP = 23, NT = 15, KS = 5, CM = 4, and PI = 4. Annual trends indicated a statistically significant decline in all OIs. However, in the Northeast and Central-West regions there were increases in TB (b = 0.39) and NT (b = 0.20), respectively. TB showed a higher incidence among individuals with less schooling (< 8 years), while PCP and KS had higher incidence rates among those with 8 or more years of schooling, despite similar downward trends. Access to antiretroviral therapy and OI prophylaxis may partially explain these results. However, data reliability, delay in reporting, OI incidence after AIDS, and reporting and diagnostic criteria are factors that also need to be carefully assessed.

Neurological disease in HIV-infected patients in the era of highly active antiretroviral treatment: a Brazilian experience

To study characteristics of neurological disorders in HIV/AIDS patients and their relationship to highly active antiretroviral treatment, a cross-sectional study was conducted in an infectious disease public hospital in Belo Horizonte, Brazil, between February 1999 and March 2000. Of the 417 patients enrolled, neurological disease was observed in 194 (46.5%) and a new AIDS-defining neurological event developed in 23.7% of individuals. Toxoplasmosis (42.3%), cryptococcosis meningitis (12.9%) and tuberculosis (10.8%) were the most common causes of neurological complications. The majority (79.3%) of patients were on highly active antiretroviral treatment and these individuals using HAART showed higher CD4 cell counts (p = 0.014) and presented stable neurological disease (p = 0.0001), although no difference was found with respect to the profile of neurological complications. The neurological diseases continue to be a frequent complication of HIV/AIDS and infections are still its main causes in Brazil, even in the highly active antiretroviral treatment era.

Missed opportunities for congenital syphilis and HIV perinatal transmission prevention

OBJECTIVE To estimate the prevalence of missed opportunities for congenital syphilis and HIV prevention in pregnant women who had access to prenatal care and to assess factors associated to non-testing of these infections. METHODS Cross-sectional study comprising a randomly selected sample of 2,145 puerperal women who were admitted in maternity hospitals for delivery or curettage and had attended at least one prenatal care visit, in Brazil between 1999 and 2000. No syphilis and/or anti-HIV testing during pregnancy was a marker for missed prevention opportunity. Women who were not tested for either or both were compared to those who had at least one syphilis and one anti-HIV testing performed during pregnancy (reference category). The prevalence of missed prevention opportunity was estimated for each category with 95% confidence intervals. Factors independently associated with missed prevention opportunity were assessed through multinomial logistic regression. RESULTS The prevalence of missed prevention opportunity for syphilis or anti-HIV was 41.2% and 56.0%, respectively. The multivariate analysis showed that race/skin color (non-white), schooling (<8 years), marital status (single), income (<3 monthly minimum wages), having sex during pregnancy, history of syphilis prior to the current pregnancy, number of prenatal care visits (<6), and last prenatal visit before the third trimester of gestation were associated with an increased risk of missed prevention opportunity. A negative association with missed prevention opportunity was found between marital status (single), prenatal care site (hospital) and first prenatal visit in the third trimester of gestation. CONCLUSIONS High rates of non-tested women indicate failures in preventive and control actions for HIV infection and congenital syphilis. Pregnant women have been discontinuing prenatal care at an early stage and are failing to undergo prenatal screening for HIV and syphilis.OBJETIVO: Estimar a prevalencia de oportunidade perdida de prevencao a sifilis e HIV entre gestantes que tiveram acesso ao pre-natal e fatores associados a nao-testagem para esses agravos. METODOS: Estudo transversal com amostra aleatoria de 2.145 puerperas do Brasil, 1999 e 2000 admitidas em maternidades para parto ou curetagem e que haviam realizado pelo menos uma consulta de pre-natal. A nao-realizacao de exame de teste para sifilis e/ou anti-HIV durante a gravidez foi usada como marcador para oportunidade perdida de prevencao. Mulheres que realizaram apenas exame de sifilis ou apenas o anti-HIV, ou nao realizaram nenhum, foram comparadas aquelas que realizaram os dois (categoria de referencia). A prevalencia de oportunidade perdida de prevencao foi estimada para cada categoria, com intervalo de confianca de 95%. Os fatores associados com oportunidade perdida de prevencao foram analisados por meio de regressao logistica multinomial. RESULTADOS: A prevalencia de oportunidade perdida de prevencao para a realizacao do teste de sifilis ou anti-HIV foi de 41,2% e 56,0%, respectivamente. A analise multivariada indicou que raca/cor (nao branca), escolaridade (< 8 anos de estudo), estado civil (solteira), renda <3 salarios minimos, relacao sexual durante a gravidez, relato de nao ter tido sifilis anterior a gravidez atual, realizacao de seis ou mais consultas de pre-natal e a realizacao da ultima visita antes do terceiro trimestre de gravidez estavam associados a maior risco de ter oportunidade perdida de prevencao. Observou-se uma associacao negativa entre estado civil (solteira), local de realizacao do pre-natal (hospital) e a realizacao da primeira consulta de pre-natal no terceiro trimestre com oportunidade perdida de prevencao. CONCLUSOES: Altas percentagens de gestantes nao testadas apontam falhas na prevencao e controle da infeccao pelo HIV e da sifilis congenita pelos servicos de saude. As gestantes continuam interrompendo o cuidado pre-natal precocemente e nao conseguindo realizar os procedimentos de triagem para HIV e sifilis.

Prevalence of HIV, syphilis, hepatitis B and C among adults with mental illness: a multicenter study in Brazil

OBJECTIVE There is evidence that patients with mental illness have increased prevalence of sexually transmitted infections, but data in Brazil are scarce. The objective of this study was to determine the prevalence of HIV, hepatitis C and B, and syphilis among patients with mental illness in Brazil. METHOD A multicenter representative sample of adults with mental illness was randomly selected from 26 mental health institutions throughout Brazil. Sociodemographic, sexual behavior and clinical data were obtained from person-to-person interviews and blood was collected for serology testing. Seroprevalence with 95% confidence limits were obtained correcting for sampling scheme. RESULTS Of the 2,475 patients interviewed, 2,238 had blood collected. Most participants were sexually active ever (88.8%) or in the last 6 months (61.6%), female (51.9%), and single (66.6%). Half of the sample had less than 5 years of schooling and the mean monthly individual income was low (US

HIV, syphilis, and hepatitis B and C prevalence among patients with mental illness: a review of the literature

210.00). Condom use was very low either during lifetime (8%) or in the last 6 months (16%). Overall seroprevalence were 1.12%, 0.80%, 1.64%, 14.7% and 2.63% for, respectively, syphilis, HIV, HBsAg, anti-HBc and anti-HCV. CONCLUSIONS Seroprevalences found were higher than other populations with representative studies in Brazil, with high rates of sexual risk behavior. This is of public health concern, and prevention and care strategies for sexually transmitted infections among psychiatric patients should urgently be implemented by health authorities.

Factors associated with psychiatric treatment dropout in a mental health reference center, Belo Horizonte

A limited number of studies worldwide have investigated the prevalence of HIV, syphilis, and hepatitis B and C infection among psychiatric patients. However, prevalence of these infections in the population with chronic mental illness has not been clearly established. Most of the published papers are from developed countries and have derived from relatively small and non-representative samples. We performed a systematic review of the published literature to identify studies on these infectious diseases within psychiatric populations in Brazil and other developing countries. Overall, prevalence rates varied from 0% to 29% for HIV; 1.6% to 66% for HBV; 0.4% to 38% for HCV; and 1.1% to 7.6% for syphilis. Several risk factors were identified and discussed, although sampling limitations restrict the generalization of study findings. This review highlights the lack of information on the prevalence of sexually transmitted diseases and their associated factors among persons with chronic mental illness and identifies gaps in the knowledge base in both developing and developed countries.

Quality of life among HIV-infected patients in Brazil after initiation of treatment

OBJECTIVE To characterize an outpatient public referral center for mental health and to assess factors associated with treatment dropout. METHODS A non-concurrent prospective study was undertaken to review 295 patient files. Patients, whose first consultation took place between January and December 1997, were followed-up for at least four months until April 1998. Patients were considered as having abandoned their treatment when, following a recommendation for at least a second visit, they did not return within four months after the first consultation. Social, demographic and clinical variables were compared to verify possible factors associated with dropout of treatment. Statistical analysis was performed using relative hazard (RR) with 95% confidence interval (CI) estimated by the Cox Regression Model. RESULTS Cumulative incidence of treatment dropout was 39.2% while multivariate analysis indicated that the following characteristics were statistically associated with treatment interruption: to live outside the referral area (RR = 1.95), no history of previous psychiatric hospitalizations (RR = 1.88), alcohol or drug use at admission (RR = 1.72), spontaneous demand to the service (RR = 2.12), lack of bus-passes (RR = 3.68) and to have less than four clinical appointments (RR = 7.31). CONCLUSIONS Our findings suggest that services should be aware of the high incidence of treatment interruption, especially among those with no history of previous psychiatric hospitalizations and with less institutional bonds. This may indicate that mental health services should develop and implement public policies targeted at this population.

Adesão à terapia anti-retroviral (HIV/aids): fatores associados e medidas da adesão

INTRODUCTION Despite improvement in clinical treatment for HIV-infected patients, the impact of antiretroviral therapy on the overall quality of life has become a major concern. OBJECTIVE To identify factors associated with increased levels of self-reported quality of life among HIV-infected patients after four months of antiretroviral therapy. METHODS Patients were recruited at two public health referral centers for AIDS, Belo Horizonte, Brazil, for a prospective adherence study. Patients were interviewed before initiating treatment (baseline) and after one and four months. Quality of life was assessed using a psychometric instrument, and factors associated with good/very good quality of life four months after the initiation of antiretroviral therapy were assessed using a cross-sectional approach. Logistic regression was used for analysis. RESULTS Overall quality of life was classified as ‘very good/good’ by 66.4% of the participants four months after initiating treatment, while 33.6% classified it as ‘neither poor nor good/poor/very poor’. Logistic regression indicated that >8 years of education, none/mild symptoms of anxiety and depression, no antiretroviral switch, lower number of adverse reactions and better quality of life at baseline were independently associated with good/very good quality of life over four months of treatment. CONCLUSIONS Our results highlight the importance of modifiable factors such as psychiatric symptoms and treatment-related variables that may contribute to a better quality of life among patients initiating treatment. Considering that poor quality of life is related to non-adherence to antiretroviral therapy, careful clinical monitoring of these factors may contribute to ensuring the long-term effectiveness of antiretroviral regimens.
