Factors associated to the control of viral load in HIV positive patients / Factores asociados con el control de la carga viral en pacientes con VIH

Objective: to evaluate factors associated with inadequate control of viral load in individuals with Human Immunodeficiency Virus (HIV) in the The Center for Assistance to Sexually Transmitted Infections/SIDA/Viral Hepatitis (CAP) of Itajubá, MG, Brazil. The acquired immunodeficiency syndrome remains a health challenge in Brazil. Therapeutic failures, characterized by detectable viral load, must have their causes evaluated. Among the most relevant reasons is the lack of adherence to treatment. Materials and methods: this is an observational, cross-sectional and documentary study of 261 medical records. The variables analyzed were socio-epidemiological characteristics and laboratory tests for viral load and CD4+ T lymphocytes, poor adherence in history or currently, duration of antiretroviral therapy (ART) use, depression and/or anxiety, use of illicit drugs, follow-up time at the CAP. Results: among the patients, 90.42% had an undetectable viral load and 64.37% had a CD4+ T count ≥500 in the last available test. Some characteristics were related to detectable viral load in the last exam: history of poor adherence during treatment (p<0,0001), inconsistent use of ART (p<0,0001) and use of illicit drugs (p=0,0155). Anxiety and/or depression were not statistically significant (p=0,3321). Conclusion: history of poor adherence, inconsistent use of ART and use of illicit drugs were associated with an increased risk of virologic failure. Early identification of groups at risk of poor adherence to treatment can support the development of intervention strategies in an transdisciplinary way to improve adherence and generate better results in the control of HIV infection..Au

Objetivo: evaluar los factores asociados con el control inadecuado de la carga viral en individuos con virus de inmunodeficiencia humana (VIH) en el Centro de Asistencia para Infecciones de Transmisión Sexual/SIDA/Hepatitis Viral (CAP) de Itajubá, MG, Brazil. El síndrome de inmunodeficiencia adquirida sigue siendo un desafío para la salud en Brasil. Las fallas terapéuticas, caracterizadas por una carga viral detectable, deben tener sus causas evaluadas. Entre las razones más relevantes está la falta de adherencia al tratamiento. Materiales y métodos: estudio observacional, transversal y documental con 261 registros médicos. Las variables analizadas fueron características socioepidemiológicas y pruebas de laboratorio para carga viral y linfocitos T CD4+, pobre adherencia en la historia o en la actualidad, duración del uso de terapia antirretroviral (ARTE), depresión. y/o ansiedad, uso de drogas ilícitas, tiempo de seguimiento en el CAP. Resultados: de los pacientes, el 90.42% tenía una carga viral indetectable y el 64.37% tenía un recuento de CD4 + T ≥500 en la última prueba disponible. Fueron evidenciadas características relacionadas con la carga viral detectable en el último examen: antecedentes de mala adherencia durante el tratamiento (p <0,0001), uso inestable de ARTE (p <0,0001) y uso de drogas ilícitas (p = 0 , 0155). La ansiedad y / o depresión no fue estadísticamente significativa (p = 0.3321). Conclusión: el historial de adherencia deficiente, el uso inconsistente de ART y el uso de drogas ilícitas se asociaron con un mayor riesgo de falla virológica. La identificación de grupos en riesgo de mala adherencia al tratamiento puede ayudar a desarrollar estrategias de intervención de manera temprana y entre disciplinas para mejorar la adherencia y generar mejores resultados en el control de la infección por VIH..Au

Associação entre fatores de risco cardiovasculares e a presença de doença arterial coronariana / Association between cardiovascular risk factors and the presence of coronary artery disease

Objetivo: associar os fatores de risco e a presença da doença arterial coronariana em pacientes submetidos à cintilografia de perfusão de miocárdio. A doença arterial coronariana é uma das principais causas de morte no Brasil e no mundo por isso, detectá-la anteriormente às manifestações clínicas ou complicações é crucial para evitar a progressão da doença. Materiais e Métodos: foi realizado um estudo observacional, transversal e retrospectivo a partir da análise aleatória de 226 prontuários de pacientes submetidos a cintilografia de perfusão do miocárdio entre agosto de 2010 e agosto de 2015. Avaliou-se a razão de chances (Odds Ratio) dos seguintes fatores de risco: tabagismo, diabetes mellitus tipo II, hipertensão arterial sistêmica, dislipidemia, obesidade, sobrepeso, sedentarismo, estresse e antecedentes familiares. Foram calculados riscos atribuíveis ao Intervalo de Confiança 95%. Resultados: dentre os fatores analisados, o diabetes aparece como o principal fator de risco não evitável para a doença com razão de chances ajustada de 3,45 (Intervalo de confiança 95%). A dislipidemia com Odds Ratio ajustada de 2,45 (Intervalo de confiança 95%) e hipertensão com Odds Ratio ajustada de 1,97 (Intervalo de confiança 95%). Conclusões: o presente estudo permitiu associar os fatores de risco e a presença da doença arterial coronariana em pacientes submetidos à cintilografia de perfusão de miocárdio, sendo o diabetes o principal fator de risco não evitável para a doença. Dentre os fatores de risco evitáveis (tabagismo,sedentarismo, estresse, sobrepeso/obesidade e sobrepeso) nenhum apresentou associação significativa com a doença..(AU)

Objective: to associate the risk factors and presence of coronary artery disease in patients submitted to myocardial perfusion scintigraphy. Coronary artery disease is one of the leading causes of death in Brazil and around the world so detecting it prior to clinical manifestations or complications is crucial to prevent disease progression. Materials and Methods: an observational, cross-sectional and retrospective study was performed from a randomized analysis of 226 medical records of patients undergoing myocardial perfusion scintigraphy between August 2010 and August 2015. Odds Ratio (odds ratio) of the following risk factors: smoking, type II diabetes mellitus, systemic arterial hypertension, dyslipidemia, obesity, overweight, sedentary lifestyle, stress and family history. Risks attributable to the 95% Confidence Interval were calculated. Results:among the factors analyzed, diabetes appears as the main non-avoidable risk factor for the disease with an adjusted odds ratio of 3.45 (95% confidence interval). Dyslipidemia with adjusted Odds Ratio of 2.45 (Confidence Interval 95%) and hypertension with adjusted Odds Ratio of 1.97 (95% Confidence Interval). Conclusions:the present study allowed to associate the risk factors and the presence of coronary artery disease in patients submitted to myocardial perfusion scintigraphy, with diabetes being the main non-avoidable risk factor for the disease. Among the avoidable risk factors (smoking, sedentary lifestyle, stress, overweight / obesity and overweight) none of them had a significant association with the disease..(AU)
