Rheumatoid arthritis; experiences with hydrocortisone (free alcohol) and hydrocortisone acetate.

Recent experimental evidence suggests that hydrocortisone (Kendall's Compound F) is probably the principal glycogenic steroid secreted by the adrenal cortex and that under conditions of stress it may participate more than cortisone in physiologic reactions. Laboratory studies indicate that hydrocortisone has greater physiologic activity, milligram for milligram, than cortisone and with certain assays its potency is twice as great.Two forms of hydrocortisone, the free alcohol preparation and the acetate, were given systemically to patients with rheumatoid arthritis and were observed to possess significant differences in ability to suppress the disease manifestations. When administered orally in large initial doses, hydrocortisone (free alcohol) appeared to produce greater suppressive effects, milligram for milligram, than either hydrocortisone acetate or cortisone acetate. Comparisons of potency made by determining maintenance dosage requirements for equivalent degrees of clinical control in the same patients indicated that the effectiveness of hydrocortisone (free alcohol) is more than 50 per cent greater than that of either the free or acetated forms of cortisone and approximately twice as great as that of hydrocortisone acetate. Certain observations suggested that the greater antirheumatic activity of hydrocortisone (free alcohol) is not accompanied by a correspondingly greater tendency toward endocrine complications. If more extensive future investigations support this observation, hydrocortisone (free alcohol), by producing equally efficient results with smaller doses, may prove superior to cortisone as a therapeutic agent.Intra-articular injections of hydrocortisone acetate appear to have only a limited place in the management of rheumatoid arthritis but may be used for temporary relief under certain conditions. In preliminary studies by the author it was noted that whereas improvement resulted in 80 per cent of the treated joints, the improvement was graded as pronounced or very pronounced in only one-half of the joints so injected. In almost all instances the benefits derived were quite temporary. Results observed in treatment of osteoarthritic joints by this method were decidedly poorer than in rheumatoid arthritis.
