OBJECTIVE To discuss the effect of glucocorticoid (methylprednisolone) on severe acute respiratory syndrome (SARS). METHODS Thirty SARS patients were treated at our hospital for over 3 weeks since March to May 2003. The course and dosage of glucocorticoid, counts of CD(4)(+), CD(8)(+) and CD(3)(+), electrolytes, blood routine, and sera albumin before and after the treatment were analysed. RESULTS Before treatment by methylprednisolone, the counts of CD(4)(+), CD(8)(+) and CD(3)(+) of 27 SARS patients were (401 +/- 203), (340 +/- 187), (756 +/- 383) cells/ microl. Twenty-nine of the 30 SARS patients were treated by methylprednisolone. The dosage for 24 patients was 80 - 160 mg/d with the largest being 1,000 mg/d before admission to the hospital. The count of WBC was increased after treatment (P < 0.01). No obvious effect was observed on the potassium, sodium and chlorine of blood (P > 0.05). Glucocorticoid increased the level of blood glucose (P = 0.01), decreased the level of sera albumin (P < 0.01), and its large dosage decreased the counts of CD(4)(+), CD(8)(+) and CD(3)(+). Three severe patients had secondary infection after administration of a large dose of glucocorticoid. CONCLUSIONS In the early stage of the disease, the counts of CD(4)(+), CD(8)(+) and CD(3)(+) of SARS patients may reduce markedly indicating the immunity is suppressed. A large dose of glucocorticoid may aggravate the suppression and make the body in an active metabolic state (the increase of blood glucose and the decrease of sera albumin). Thus the disease is aggravated and patients are likely to suffer from severe secondary infection. Indications for use of glucocorticoid must strictly controlled and its large dosage is improper.
