ABSTRACT

BACKGROUND: Cardiomyopathy associated with partial lipodystrophy (PL) has not been well described yet. OBJECTIVE: To characterize cardiac morphology and function in PL. METHODS: Patients with familial PL and controls were prospectively assessed by transthoracic echocardiography and with speckle-tracking echocardiography (global longitudinal strain, GLS). The relationship between echocardiographic variables and PL diagnosis was tested with regression models, considering the effect of systolic blood pressure (SBP). Significance level of 5% was adopted. RESULTS: Twenty-nine patients with PL were compared to 17 controls. They did not differ in age (p=0.94), gender or body mass index (p= 0.05). Patients with PL had statistically higher SBP (p=0.02) than controls. Also, PL patients had higher left atrial dimension (37.3 ± 4.4 vs. 32.1 ± 4.3 mm, p= 0.001) and left atrial (30.2 ± 7.2 vs. 24.9 ± 9.0 mL/m2,p=0.02), left ventricular (LV) mass (79.3 ± 17.4 vs. 67.1 ± 19.4, p=0.02), and reduced diastolic LV parameters (E' lateral, p= 0.001) (E' septal, p= 0.001), (E/E' ratio, p= 0.02). LV ejection fraction (64.7 ± 4.6 vs. 62.2 ± 4.4 %, p= 0.08) and GLS were not statistically different between groups (-17.1 ± 2.7 vs. -18.0 ± 2.0 %, p= 0.25). There was a positive relationship of left atrium (ß 5.6, p<0.001), posterior wall thickness, (ß 1.3, p=0.011), E' lateral (ß -3.5, p=0.002) and E' septal (ß -3.2, p<0.001) with PL diagnosis, even after adjusted for SBP. CONCLUSION: LP patients have LV hypertrophy, left atrial enlargement, and LV diastolic dysfunction although preserved LVEF and GLS. Echocardiographic parameters are related to PL diagnosis independent of SBP.


FUNDAMENTO: A cardiomiopatia associada à lipodistrofia parcial (LP) ainda não foi bem descrita. OBJETIVO: Caracterizar a morfologia e a função cardíaca na LP. MÉTODOS: Pacientes com LP e controles foram avaliados prospectivamente por ecocardiografia transtorácica e ecocardiografia por speckle-tracking (Strain Longitudinal Global, SLG). A relação entre as variáveis ecocardiográficas e o diagnóstico de LP foi testada com modelos de regressão, considerando o efeito da pressão arterial sistólica (PAS). Adotou-se um nível de significância de 5%. RESULTADOS: Vinte e nove pacientes com LP foram comparados com 17 controles. Eles não se diferiram quanto à idade (p=0,94), sexo ou índice de massa corporal (p= 0,05). Os pacientes com LP apresentaram PAS estatisticamente mais alta (p=0,02) em comparação aos controles. Ainda, os pacientes com LP apresentaram maior dimensão do átrio (37,3 ± 4,4 vs. 32,1 ± 4,3 mm, p= 0,001) e maior volume atrial (30,2 ± 7,2 vs. 24,9 ± 9,0 mL/m2, p=0,02), massa do Ventrículo Esquerdo (VE) (79,3 ± 17,4 vs. 67,1 ± 19,4; p=0,02), e parâmetros sistólicos reduzidos do VE (E' lateral, p= 0,001) (E' septal, p= 0,001), (razão E/E', p= 0,02). A fração de ejeção do VE (64,7 ± 4,6 vs. 62,2 ± 4,4 %, p = 0,08) e o SLG não foram estatisticamente diferentes entre os grupos (-17,1±2,7 vs-18.0 ± 2,0%, p= 0,25). Observou-se uma reação positiva do átrio esquerdo (ß 5,6; p<0,001), espessura da parede posterior (ß 1,3; p=0,011), E' lateral (ß -3,5; p=0,002) e E' septal (ß -3,2; p<0,001) com o diagnóstico de LP, mesmo após o ajuste para a PAS. CONCLUSÃO: Os pacientes com LP apresentam hipertrofia do VE, aumento do átrio esquerdo, e disfunção diastólica do VE apesar de fração de ejeção do VE e SLG preservados. Os parâmetros ecocardiográficos estão relacionados com o diagnóstico de LP, independentemente da PAS.

ABSTRACT

Familial lipodystrophy is a rare genetic condition in which individuals have, besides metabolic changes and body fat deposits, a type of cardiomyopathy that has not been well studied. Many of the patients develop cardiovascular changes, the most commonly reported in the literature being the expression of a type of hypertrophic cardiomyopathy. This article, presented as a bibliographic review, reviews the clinical and cardiovascular imaging aspects in this scenario of cardiomyopathy in a rare metabolic disease, based on the latest scientific evidence published in the area. Despite the frequent association of congenital lipodystrophy and ventricular hypertrophy described in the literature, the pathophysiological mechanisms of this cardiomyopathy have not yet been definitively elucidated, and new information on cardiac morphological aspects is emerging in the aegis of recent and advanced imaging methods, such as cardiac magnetic resonance.

Resumo A lipodistrofia familiar é uma condição genética rara na qual indivíduos apresentam, além das alterações metabólicas e de depósitos de gordura físicos, um tipo de cardiomiopatia pouco estudada. Muitos dos pacientes desenvolvem alterações cardiovasculares, sendo a mais comumente reportada em literatura, a expressão de um tipo de cardiomiopatia hipertrófica. Este artigo, apresentado como uma revisão bibliográfica, revisa os aspectos clínicos e de imagem cardiovascular neste cenário de cardiomiopatia em doença metabólica rara, com base nas últimas evidências científicas publicadas na área. Apesar da frequente associação de lipodistrofia congênita e hipertrofia ventricular descrita em literatura, os mecanismos fisiopatológicos desta cardiomiopatia ainda não estão definitivamente elucidados, e novas informações do aspecto morfológico cardíaco surgem à égide de recentes e avançados métodos de imagem como a ressonância cardíaca magnética.

ABSTRACT

OBJECTIVE: The prevalence of type 2 diabetes has shown a significant increase in parallel with health care costs. The objective of the Brazilian Study on Diabetes Costs (ESCUDI study) was to estimate direct and indirect costs of type 2 diabetes outpatient care in the Brazilian Public Health Care System. METHODS: Data were collected from different levels of health care in eight Brazilian cities in 2007. A total of 1000 outpatients were interviewed and had their medical records data analyzed. Direct medical costs included expenses with medications, diagnostic tests, procedures, blood glucose test strips, and office visits. Nonmedical direct costs included expenses with diet products, transportation, and caregivers. Absenteeism, sick leave, and early retirement were classified as indirect costs. RESULTS: Total annual cost for outpatient care was US$2108 per patient, out of which US$1335 per patient of direct costs (63.3%) and US$773 per patient of indirect costs (36.7%). Costs escalated as duration of diabetes and level of health care increased. Patients with both microvascular and macrovascular complications had higher costs (US$3199 per patient) compared to those with either microvascular (US$2062 per patient) or macrovascular (US$2517 per patient) complications only. The greatest portion of direct costs was attributed to medication (48.2%). CONCLUSIONS: Diabetes treatment leads to elevated costs both to Brazilian Public Health Care System and society. Costs increased along with duration of disease, level of care and presence of chronic complications, which suggested a need to reallocate health resources focusing on primary prevention of diabetes and its complications.

ABSTRACT

Estudamos retrospectivamente 48 casos de coagulopatias hereditárias, clientes do ambulatório da Faculdade de Medicina de Sao José do Rio Preto, provenientes da cidade e regiao. Encontramos predominância da deficiência de fator VIII e raros casos diagnosticados como doença de von Willebrand. História familiar está presente numa minoria dos casos. A média das idades foi de 17,9 anos e a do aparecimento das primeiras manifestaçoes hemorrágicas, de 2,3. Hematomas foram a manifestaçao mais frequente. A contaminaçao com Hepatites C, B, HIV e Chagas foi de 56 por cento dos casos, sendo que acima de 50 por cento dos pacientes estao presumivelmente em atividade sexual, colocando seus parceiros sob risco. Sequelas ortopédicas estao presentes em 41,67 por cento dos casos. Como causa de morte, a maioria foi devida a hemorragias maciças, sendo que os cuidados hemoterápicos foram considerados insuficientes. Anemia ferropriva está presente em 20 por cento dos casos, exigindo pronto diagnóstico, tratamento e profilaxia. Um terço dos casos sao crianças abaixo de 10 anos de idade, sem ou com poucas sequelas e soronegativos, exigindo cuidados especiais. Evitar as manifestaçoes presentes nos mais idosos e melhorar a qualidade de vida atrvés do aporte de quantidade adequada de fatores e pessoal treinado para usá-lo corretamente, através de equipe multidisciplinar, é nosso objetivo imediato.
