IMPAIRED QUALITY OF LIFE IN CHAGAS ACALASIA PATIENTS AND ASSOCIATED CLINICAL FACTORS.

BACKGROUND: No study has focused on Health-Related Quality of Life (HRQoL) for Chagas Achalasia patients. Objective: To compare HRQoL between Chagas Achalasia patients and the general population; and to correlate HRQoL with clinical factors that can affect it. METHODS: Sixty Chagas Achalasia patients and 50 controls were evaluated. All patients underwent esophageal manometry for the diagnosis of achalasia and esophagogram to determine the grade of megaesophagus. Three questionnaires were used: 1) clinical: the following data were collected: demographic, medical history, body mass index, occurrence of six esophageal symptoms (Esophageal Symptom Score: number of symptoms reported by patients), duration of dysphagia; 2) socio-economic-cultural status evaluation: patients and controls answered seven questions about their socio-economic-cultural conditions; 3) HRQoL: the validated Brazilian-Portuguese version of the Short-form Health Survey (SF-36) questionnaire (license QM020039) was used. It measures health in eight domains: 3a) four physical: physical functioning, role limitations relating to physical health, bodily pain, and general health perception; 3b) four mental: vitality, social functioning, role limitations relating to emotional health, and mental health. These domains can be summarized into Physical and Mental Summary scores. We analyzed correlations between SF-36 Physical/Mental Summary Component scores and the following clinical factors: Esophageal Symptom Score, duration of dysphagia, body mass index, grades of megaesophagus (defined by the esophagogram) and presence/absence of megacolon (defined by opaque enema). RESULTS: Patients and controls had similar age, gender, medical history, and socio-economic-cultural lifestyles (P>0.05). All patients had dysphagia and megaesophagus. SF-36 scores were significantly lower in Chagas Achalasia patients than controls for all eight domains (physicals: P<0.002; mentals: P<0.0027). The Physical and Mental Summary Component scores were also lower in Chagas Achalasia patients than controls (P<0.0062). For patients, the Physical Summary score was negatively correlated to Esophageal Symptom Score (P=0.0011) and positively correlated to body mass index (P=0.02). No other correlations were found. CONCLUSION: Chagas Achalasia patients have an impaired HRQoL in all physical and mental domains. Patients reporting more symptoms had worse physical domains. Patients with higher body mass index had better physical domains.

RESUMO Contexto: Não encontramos na literatura estudos sobre a qualidade de vida em pacientes com acalásia chagásica especificamente. Objetivo: Comparar a qualidade de vida de pacientes com acalásia chagásica e a da população em geral. Também, correlacionar a qualidade de vida nestes pacientes com fatores clínicos que possam afetá-la. Métodos: Estudamos 60 pacientes com acalásia chagásica e 50 controles. Todos os pacientes foram submetidos à manometria esofágica para diagnóstico de acalásia e esofagograma técnica padrão para determinar o grau do megaesôfago. Usamos 3 questionários: 1) clínico: foram coletados os seguintes dados: demográficos, história clínica, índice de massa corporal, presença de seis sintomas esofágicos (definimos Escore de Sintomas Esofágicos como o número de sintomas relatados pelos pacientes), duração da disfagia; 2) avaliação sócio-econômico-cultural: sete questões sobre as condições sócio-econômico-culturais foram perguntadas para pacientes e controles; 3) qualidade de vida: foi avaliada pelo questionário SF-36, versão validada para o português-Brasil (licença QM020039). Este é um questionário genérico que mede a qualidade de vida em oito domínios: 3a) quatro físicos: capacidade funcional, aspectos físicos, dor corporal, estado geral de saúde; 3b) quatro mentais: vitalidade, aspectos sociais, aspectos emocionais, saúde mental. Estes oito domínios podem ser compilados em dois escores: Sumário dos Escores Físicos e Sumário dos Escores Mentais. Na análise de fatores clínicos que pudessem afetar a qualidade de vida dos pacientes, avaliamos: escores de sintomas esofágicos, duração da disfagia, índice de massa corporal, graus de megaesôfago e presença/ausência de megacólon. Resultados: Os dois grupos (pacientes e controles) apresentaram semelhantes idade, gênero, história médica e condições socioeconômico-culturais (P>0,05). Todos os pacientes tinham disfagia e megaesôfago. Com relação à qualidade de vida, pacientes com acalásia chagásica apresentaram valores significativamente menores do que os controles em todos os domínios do questionário SF-36 (domínios físicos: P<0,002; domínios mentais: P<0,0027). Os Sumários dos Escores Físicos e Mentais também foram significativamente menores em pacientes do que nos controles (P<0.0062). A análise dos fatores clínicos que poderiam afetar a qualidade de vida nos pacientes mostrou que o Sumário dos Escores Físicos se correlaciona negativamente com o Escores Dos Sintomas Esofágicos (P=0,0011) e positivamente com o índice de massa corporal (P=0,02). Não observamos qualquer outra correlação. Conclusão: Pacientes com Acalásia Chagásica têm pior qualidade de vida que a população em geral, em todos os domínios físicos e mentais. Pacientes que relataram mais sintomas apresentaram pior qualidade de vida nos domínios físicos. Pacientes com valores maiores de índice de massa corporal apresentaram melhor qualidade de vida nos domínios físicos.

Association of Lower Adiponectin Plasma Levels, Increased Age and Smoking with Subclinical Atherosclerosis in Patients with HIV-1 Infection.

BACKGROUND: The association between subclinical atherosclerosis and traditional cardiovascular disease (CVD) risk factors, inflammatory and metabolic biomarkers has been demonstrated around the world and specifically Brazilian human immunodeficiency virus type 1 (HIV-1)- infected individuals. However, the association between subclinical atherosclerosis and these aforementioned factors combined with anti-inflammatory biomarkers has not been examined in these populations. OBJECTIVES: To evaluate the association of the carotid intima-media thickness (cIMT) with CVD risk factors, inflammatory, metabolic and HIV-1 infection markers combined with adiponectin and interleukin (IL)-10 as anti-inflammatory variables. METHODS: In this case-control study, 49 HIV-1-infected patients on combined antiretroviral therapy (cART) and 85 controls were compared for traditional CVD risk factors, inflammatory, metabolic, and anti-inflammatory variables. Further, we compared HIV-1-infected patients according to their cIMT (as continuous and categorized <0.9 or ≥0.9 mm variable) visualized by carotid ultrasonography doppler (USGD). RESULTS: Twenty-four (48.9%) HIV-1-infected patients showed cIMT ≥0.9 mm. The patients had higher levels of C reactive protein on high sensitivity assay (hsCRP), tumor necrosis factor α, IL-6, IL-10, triglycerides, and insulin, and lower levels of adiponectin, total cholesterol and low-density lipoprotein cholesterol than controls (all p<0.05). Low levels of adiponectin were negatively associated with cIMT ≥0.9 mm (p=0.019), and explained 18.7% of the cIMT variance. Age (p=0.033) and current smoking (p=0.028) were positively associated with cIMT values, while adiponectin levels (p=0.008) were negatively associated with cIMT values; together, these three variables explained 27.3% of cIMT variance. CONCLUSION: Low adiponectin was associated with higher cIMT in HIV-1-infected patients on cART. Low adiponectin levels in combination with age and smoking could explain, in part, the increased subclinical atherosclerosis observed in these patients. Adiponectin may be a good candidate for predicting subclinical atherosclerosis in the management of HIV-1-infected patients in public health care, especially where USGD is not available.
