ABSTRACT
Abstract Background Patient self-report is the most common diagnostic tool in the literature to detect HIV/HAART-associated lipodystrophy. However, data on the association of cardiovascular risk factors with HIV/HAART-associated lipodystrophy assessed by self-report are still missing. Objectives To determine the prevalence of self-reported HIV/HAART-associated lipodystrophy and to identify independent associations between traditional modifiable cardiovascular risk factors and self-reported lipodystrophy. Methods We conducted a retrospective observational study at an outpatient infectious disease clinic in the Central-West of Brazil to identify the association between traditional modifiable cardiovascular risk factors and self-reported lipodystrophy. Sedentary lifestyle, smoking status, family history of cardiovascular disease, hypertension, diabetes, dyslipidemia, increased waist circumference and overweight were the cardiovascular risk factors assessed. Self-reported HIV/HART-associated lipodystrophy was categorized as: mild (noticeable by patients' close inspection), moderate (easily noticeable by patient and physician) or severe (readily noticeable by a casual observer). Prevalence ratio (PR) and 95% confidence interval (CI95%) were calculated. Multivariate Poisson's regression was used to analyze factors associated to HIV/HAART-associated lipodystrophy assessed by self-report considering a significance level of 5%. Results A total of 183 patients were included, with a mean age of 39.3±10.9 years. Most of the sample were male (77.6%), non-white (50.8%) and single (53.0%). The overall prevalence of HIV/HAART-associated lipodystrophy was 52.5% (95% CI 44.96 - 59.88). Severe lipodystrophy was observed in more than half patients (55.2%). No traditional modifiable cardiovascular risk factor was independently associated with lipodystrophy. Female sex (PR 1.49; 95% CI 1.15 - 1.95; p =0.003), time of HIV infection diagnosis of 1-3 years (PR 1.83; 95% CI 1.09 - 3.08; p =0.002) and a positive family history of CVD (PR 1.62; 95% CI 1.11 - 2.36; p <0.001) were independently associated with lipodystrophy. Conclusion HIV/HAART-associated lipodystrophy assessed by patient self-report was not associated with traditional modifiable cardiovascular risk factors.

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.
