Abstract

To assess the potential effect of serum leptin levels in human immunodeficiency virus (HIV)-related wasting. Morning serum leptin levels of 94 randomly chosen HIV-infected patients were measured and correlated with age, sex, weight, height, body mass index (BMI), routine blood chemistries (SMA 18), complete blood cell count, HIV viral load, and CD4/CD8 ratio. The mean serum leptin level was 7.0 +/- 6.9 ng/mL. Leptin levels were significantly higher in the 38 female patients than in the 56 male patients (10.0 +/- 8.4 ng/mL versus 5.0 +/- 4.9 ng/mL; P<0.001). Leptin levels were positively correlated with BMI (r = 0.71; P<0.05). The correlation of leptin levels with BMI was improved when the results were analyzed stratified by the sex of the patients (r = 0.74 for female patients; r = 0.81 for male patients). This study showed that the serum leptin levels in HIV-infected patients with BMI between 18 and 25 kg/m 2 were comparable to leptin levels in lean, healthy subjects. Leptin distribution was positively correlated with BMI, as expected. These data do not support the hypothesis for a major role of serum leptin in HIV-related wasting.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.
