Megestrol acetate vs cyproheptadine in the treatment of weight loss associated with HIV infection.

Two appetite stimulants, megestrol acetate and cyproheptadine were administered in a randomized trial to 14 patients who had no evidence of opportunistic infection or malabsorption but were wasted (had lost more than 5 kg body weight) as a result of human immunodeficiency virus (HIV) infection. Energy intakes were calculated from a 7 day weighed dietary record. Mean energy intakes per kilogramme body weight were similar in both treatment groups (greater than 34 kcal/kg) and were higher than that in well British males. Energy intakes increased by just over 500 kcal during both treatments, but fell to pretreatment levels after therapy. Patients in both treatment groups gained a moderate amount of weight. Megestrol acetate was associated with impotence in 4 patients. Insufficient calorie intake alone is not a common cause of wasting associated with HIV and the role of appetite stimulants is likely to be limited.     

Rheumatologic manifestations of infection with human immunodeficiency virus (HIV)

PURPOSE: To review the various rheumatologic manifestations of human immunodeficiency virus (HIV) infection and to discuss their potential pathogenic mechanisms. DATA IDENTIFICATION: A literature search using MEDLINE (1981 to 88) and Index Medicus (1981 to 88) and review of references from all identified articles. STUDY SELECTION: All studies and case reports addressing arthritis, myopathies, vasculitis, the sicca syndrome, systemic lupus erythematosus, and autoimmune phenomena in HIV-infected patients are cited. RESULTS OF DATA SYNTHESIS: The Reiter syndrome and other reactive arthritides are the commonest arthritides seen in HIV-infected patients. Psoriatic arthritis and septic arthritis with opportunistic agents, as well as an articular pain that is severe, acute, and intermittent, may also occur with HIV infection. An arthritis that may be specific for the acquired immunodeficiency syndrome (AIDS) has been described. Myopathies, especially of a polymyositic type, vasculitis, and the sicca syndrome are also part of the spectrum of rheumatologic presentation of HIV infection. Several autoimmune phenomena, such as antinuclear and anticardiolipin antibodies, as well as lupus anticoagulant, have been reported in HIV-infected patients. CONCLUSIONS: The Reiter syndrome, reactive arthritis, polymyositis, and the sicca syndrome may herald the onset of clinically evident HIV infection. These diseases and others may also occur in patients with full-blown AIDS. Furthermore, HIV infection may mimic systemic lupus erythematosus.     

Endocrine manifestations of human immunodeficiency virus (HIV) infection

Endocrine manifestations of HIV infection include both pathological changes and disturbances in function. Mechanisms include direct infection of glands by HIV or opportunistic organisms, infiltration by neoplasms, side effects of drugs, and production of humoral factors that may alter metabolism. The adrenal gland is most often affected, but virtually every endocrine system may be involved. Dysfunction is often subtle, with symptoms overlapping those of the HIV infection itself. Endocrine manifestations may be found at any time in the course of the disease, from the asymptomatic HIV-positive stage through full-blown AIDS. Optimal management of these patients may include a careful search for, and appropriate treatment of, associated endocrine abnormalities.     

Rheumatologic manifestations of infection with the human immunodeficiency virus (HIV)

The aim of this study was to assess the type and frequency of rheumatologic manifestations among patients followed at an HIV clinic in a general hospital, and to evaluate the usefulness of a questionnaire in identifying the presence of these manifestations. Fifty-two consecutive patients with HIV infection completed a questionnaire regarding the presence of rheumatologic symptoms. All patients were interviewed and examined for the prevalence and spectrum of musculoskeletal manifestations. The questionnaire was found to be sensitive in identifying patients with rheumatologic manifestations which were detected on clinical examination. The latter were found in 34 patients (65.3%). Twenty-one patients (40.3%) had arthralgias, 8 (15.2%) had spondyloarthropathies (including Reiter's syndrome, psoriatic arthritis and undifferentiated spondyloarthropathy). Two patients (3.8%) had oligoarthritis and one case each had myositis, Sj?gren's syndrome and Beh?et's syndrome. Muscle pain was common, occurring in 35% of the patients, and it was related to the use of zidovudine therapy. In contrast to previous reports, most of the patients with arthritis had mild disease, responding promptly to non-steroidal anti-inflammatory drugs. This difference may be explained by the use of zidovudine therapy, stage of HIV infection, and lifestyle. A questionnaire may be helpful in identifying the prevalence of rheumatologic manifestations in HIV-infected subjects.
