A study of adverse effects of high-dose intravenous (pulse) methylprednisolone therapy in patients with rheumatic disease.

Abstract

To determine the frequency of significant adverse effects associated with high-dose intravenous methylprednisolone therapy (HIVMP) given as methylprednisolone 1 g/d for three consecutive days. Retrospective study of consecutive patients. Department of Veterans Affairs Medical Center (VAMC), university teaching hospital, and private outpatient clinic. Eighty-four patients given HIVMP for systemic rheumatic disease. Subjective complaints were elicited via a standardized questionnaire that identified adverse effects through organ system review. Medical records were reviewed for adverse effects occurring within two weeks of HIVMP therapy. Two hundred seventy-five HIVMP treatments were examined by either patient questionnaire (76 patients) and/or chart review (78 patients). Sixty-five patients described symptoms after HIVMP treatment. Most symptoms were transient in duration, mild in severity, and required no medical treatment. Chart review found 42 possible complications occurring within two weeks of HIVMP therapy. In 18 instances medical intervention was required for problems that included hypertension, seizures, gastric erosions, sepsis, and other infections. It is impossible to attribute all of the complications to HIVMP alone because of underlying disease, use of other medications at the time of therapy, or both. HIVMP has an acceptably low risk of significant adverse effects.
