Combination drug therapy and enhanced patient management techniques result in increased survival for many AIDS patients. This phenomenon has brought the issue of fatigue, a common and difficult side effect of HIV/AIDS treatment, to the forefront. Three-quarters of the AIDS patients surveyed in a recent study indicated that fatigue negatively affects their quality of life and influences their willingness to continue aggressive treatment. New advances for combating fatigue include the use of nutritional therapy, anti-depressants, anti-infectives, medications that boost the production of red blood cells, hormone replacement, exercise, massage, and acupuncture. The most common source of fatigue in HIV-positive patients is anemia, which also causes shortness of breath and dizziness. Anti-HIV medications may inhibit red blood cell production. An alternative treatment, Epoetin alfa, works by increasing low levels of naturally producing erythropoietin, a protein manufactured in the kidneys. Fatigue resulting from low testosterone levels can be treated with anabolic steroids. Poorly functioning adrenal glands can be the cause of fatigue in patients with advanced disease. Taking hydrocortisone pills is often effective. Depression is the fourth most common cause of fatigue. Antidepressants work well without traditional side effects.

Anaemia occurs in a significant number of patients with cancer, and is associated with symptoms of fatigue, dizziness, headache and decreased health-related quality of life. Clinical trials have demonstrated the ability of epoetin alfa to increase haemoglobin concentrations and reduce transfusion requirements in patients with cancer. Data from three large, open-label, community-based trials of >7000 patients, as well as a series of smaller, randomized, placebo-controlled studies, have confirmed the efficacy of treatment with epoetin alfa in patients undergoing chemotherapy. In two of the community-based studies (>2000 patients in each), patients undergoing chemotherapy received epoetin alfa, 150-300 IU/kg or 10,000-20,000 IU, three times weekly. Significant (P<0.01) increases in haemoglobin concentrations and reductions in transfusion rates were seen in both studies. Significant improvements in quality of life were also reported, as measured by the Linear Analogue Scale Assessment and the Functional Assessment of Cancer Therapy-Anaemia. Importantly, the increases in quality of life were independent of tumour response. These findings were also observed in randomized, placebo-controlled studies. The third study, in approximately 3000 patients, evaluated the efficacy of once-weekly dosing, which significantly (P<0.01) increased haemoglobin concentrations, reduced transfusion requirements and improved quality of life. Greater increases in haemoglobin concentration were associated with greater improvements in quality-of-life scores. The safety and efficacy profile of the once-weekly regimen was comparable with that of the three times weekly regimen. Maintaining optimal quality of life, while achieving tumour stabilization or regression, is essential to the successful management of patients with cancer. Epoetin alfa has been shown to increase haemoglobin concentration, decrease transfusion requirements and increase quality of life. Given the frequency of adverse sequelae associated with anaemia, its aggressive management should become an integral and routine part of cancer treatment.
