  • Title: [Dyslipemia and HIV-1 infection in intravenous drug addicts].
    Author: Muga R, Tor J, Rey-Joly C, Pardo A, Llobet P, Foz M.

    Abstract:
    BACKGROUND: It has been demonstrated that hypertriglyceridemia and hypocholesterolemia are frequent signs in homosexual patients with AIDS. Lipid abnormalities of the intravenous drug addict (IVDA) however, and its relation with infection by the human immunodeficiency virus (HIV) have not been sufficiently studied. METHODS: Four hundred thirty-five consecutive patients attended for infectious complications or for carrying out detoxication treatment were studied. Demographic (age, sex), anthropometric (weight, height), use of intravenous drugs (principal drug used, time of addiction) and analytic data (HIV-1 antibodies, total lymphocytes, CD4+ lymphocytes, serum albumin, total cholesterol, plasma triglycerides and transferrinemia) were collected. RESULTS: The age of the patients was found to be between 15-44 years of age. Ninety-five percent were heroin addicts with a time of addiction greater than 4 years. Those who were HIV-1 positive had been drug users for a longer period of time (p < 0.01), had less weight (p < 0.01), lower albuminemia (p < 0.05) and cholesterolemia (p < 0.01), as well as a lower number of CD4+ lymphocytes (p < 0.01). No differences were observed with regard to age, transferrinemia and plasma triglyceride concentration. The prevalence of hypertriglyceridemia (> 1.97 mmol/l; 175 mg/dl) was of 18% for the IVDA with HIV-1 infection and 23% for seronegative individuals (p = 0.3). Hypercholesterolemia was significantly more prevalent in HIV-1 positive individuals (20%) than in the seronegative subjects (9%) (p < 0.01). In the HIV-1 positive patients, most of whom where asymptomatic, a decrease in total cholesterol and an increase in plasma triglycerides was observed according to the decrease in the number of CD4+ lymphocytes. CONCLUSIONS: Infection by the human immunodeficiency virus is accompanied by an increase in plasma triglycerides and a decrease of total cholesterol in relation with the alteration of cellular immunity. However, heroin addicts present some differential characteristics similar to those of chronic alcoholics, poor diet, anorexia induced by opioids, autoimmunity phenomena and recurrent infections throughout drug addiction which may justify lipid abnormalities of multifactorial origin.
