Liver damage in patients with HIV and abdominal fat is associated with insulin resistance, according to research presented at the 26th Annual American Association of Clinical Endocrinologists (AACE) Scientific & Clinical Congress, May 3-7, 2017, in Austin, TX.
Researchers from Massachusetts General Hospital and McGill University Health Center analyzed data from 2 phase 3 studies of tesamorelin use in patients with HIV and excessive abdominal fat to identify “responders,” defined as participants who experienced ≥8% reduction in visceral adipose tissue (VAT).
Tesamorelin is a stabilized analogue of human growth-releasing hormone that has been previously shown to reduce VAT in patients who are HIV positive with lipodystrophy.
Among patients who received tesamorelin therapy for 26 weeks, changes in alanine aminotransferase levels correlated significantly with changes in fasting blood glucose and glycated hemoglobin A1c (HbA1c; P <.025 and P =.036, respectively). Changes in participants without hepatitis B or C were positively correlated with changes in fasting blood glucose and HbA1c (r=0.14 and 0.13; P =.061 and .076, respectively).
Positive changes were also noted in responders who underwent tesamorelin therapy for 52 weeks, with positive associations noted in fasting blood glucose, fasting insulin, and homeostatic model assessment-insulin resistance (r=0.21, 0.21, and 0.22; P =.09, .085, and .084, respectively); negative correlations were noted with adiponectin (r=0.29; P =.041).
“Changes in liver transaminases were associated with changes in glucose parameters and adiponectin in tesamorelin responders,” the researchers concluded. “This finding may account for the preservation of glucose homeostasis seen in these patients.”
