Avaliação da força muscular respiratória e dos volumes pulmonares em mulheres vivendo com HIV / Aids e apresentando lipodistrofia

Abstract

Background: Antiretroviral use promotes survival in people with HIV/AIDS, although lipodystrophy as a side effect compromises those people quality of life. Objectives: the aim of this study was to evaluate respiratory muscle strength and pulmonary volumes in women living with HIV/AIDS and developing lipodystrophy. Methods: this was a descriptive transversal study composed by 15 women age ranging from 18 to 57 years old with the diagnosis of HIV and development of lipodystrophy. It was done an anthropometric and respiratory assessment including parameters: Body Mass Index (BMI), abdominal circumference (AC), hips circumference (HC) and relation waist/hips (RW/H), minute volume (MV), respiratory rate (RR), tidal volume (TV), total lung capacity (TLC), Maximum Inspiratory Pressure (MIP) and Maximum Expiratory Pressure (MEP). Results: sample presented mean age 43,33 ± 8,54 years old, mean time of retroviral therapy use 8,02 ± 3,60 years. Mean MV, RR and TLC at ventilometry was normal and TV beyond normality rate. According to BMI, 8 women were overweight. Respiratory muscle strength evaluation showed values under usual levels in both respiratory pressures existing a negative significance between Pemax and AC increase, as well as RW/H. Conclusion: it was shown that lipodystrophy in women who live with HIV/AIDS can be related to decrease in respiratory muscle strength. Therefore, we can infer the need of physiotherapeutic attention to this population, promoting a global muscle strengthening, improvement on physical conditioning and respiratory muscle strength as much as preventing opportunistic diseases.
