Acyclovir and prednisolone treatment of acute infectious mononucleosis: a multicenter, double-blind, placebo-controlled study. Role of steroids in the treatment of infectious mononucleosis in the ambulatory college student. A double-blind study of eighty-two cases of infectious mononucleosis treated with corticosteroids. The effects of short-term corticosteroid therapy on the symptoms of infectious mononucleosis pharyngotonsillitis: a double-blind study. Dexamethasone for the treatment of sore throat in children with suspected infectious mononucleosis: a randomized, double-blind, placebo-controlled, clinical trial. Severe nasal polyposis and its impact on quality of life. The effect of a short course of oral steroids followed by long-term intranasal steroid treatment.
Ninety-four patients with infectious mononucleosis and symptoms < or = 7 days were randomized to treatment with oral acyclovir (800 mg 5 times/day) and prednisolone (0.7 mg/kg for the first 4 days, which was reduced by 0.1 mg/kg on consecutive days for another 6 days; n = 48), or placebo (n = 46) for 10 days. Oropharyngeal Epstein-Barr virus (EBV) shedding was significantly inhibited during the treatment period (P = .02, Mann-Whitney rank test). No significant effect was observed for duration of general illness, sore throat, weight loss, or absence from school or work. The frequency of latent EBV-infected B lymphocytes in peripheral blood and the HLA-restricted EBV-specific cellular immunity, measured 6 months after onset of disease, was not affected by treatment. Thus, acyclovir combined with prednisolone inhibited oropharyngeal EBV replication without affecting duration of clinical symptoms or development of EBV-specific cellular immunity. nan nan nan To evaluate the efficacy of a single oral dose of dexamethasone for pain relief in acute exudative pharyngitis associated with infectious mononucleosis.
                We conducted a randomized, double-blind, placebo-controlled pediatric emergency department-based clinical trial. Patients aged between 8 and 18 years with a sore throat from clinically suspected infectious mononucleosis were eligible. Patients were randomized to receive either an oral dose of 0.3 mg/kg (maximum, 15 mg) of dexamethasone or a placebo. Patients completed a diary of symptoms and rated their pain on a visual analog scale from 0 to 100 mm at 0 hours, 12 hours, 24 hours, 48 hours, 72 hours, and on day 7. An improvement of 20 mm from baseline on the visual analog scale was evaluated as the primary end point.
                Twenty patients were recruited in each group; mean +/- SD age was 13.5 +/- 2.8 years. In comparison with the placebo group, a significantly greater proportion of patients given dexamethasone achieved pain relief within the first 12 hours (12/20 vs 5/19; P =.03). On further follow-up, the proportions achieving pain relief were similar between groups: 11 of 20 vs 6 of 20 at 24 hours (P =.10); 11 of 20 vs 11 of 20 at 48 hours (P>.99); 15 of 20 vs 15 of 19 at 72 hours (P =.93); and 18 of 19 vs 19 of 20 at day 7 (P>.99), with dexamethasone vs placebo, respectively.
                The short-lived relief of pain in acute exudative pharyngitis in children with suspected infectious mononucleosis may suggest that a single oral dose of dexamethasone may not be sufficient and that additional doses may be necessary for ensuring lasting relief. Nasal polyposis is not a life-threatening disorder but has a great impact on the quality of life. Steroids constitute the first line of treatment of nasal polyps. The aims of this study were to evaluate the quality of life in nasal polyp patients after: (1) a short course of oral steroids; and (2) a long-term treatment with intranasal steroids.
                Patients with severe nasal polyps received either oral prednisone (n = 60) or no steroid treatment (control group, n = 18) for 2 weeks. Patients treated with steroids were also followed-up and evaluated after 12, 24, and 48 additional weeks with intranasal budesonide treatment.
                Patients with nasal polyps showed worse scores on all SF-36 domains, except for physical functioning, compared to the Spanish general population. After two weeks, patients treated with oral prednisone demonstrated a significant improvement (p < 0.05) in all impaired QoL domains compared to both control group and baseline. The mental component summary (51.0 +/- 1.2, p < 0.05) and physical component summary (51.0 +/- 0.9, p < 0.05) were improved compared to both control group and baseline. The improvement of all SF-36 domains was sustained by intranasal budesonida (p < 0.05) after 12, 24, and 48 weeks. Nasal obstruction, sense of smell, and polyp size also improved after both the oral short course and the intranasal long-term steroids treatment (p < 0.05).
                These results suggest that the treatment with a short-course of oral steroids improves the quality of life of patients with severe nasal polyps and that this effect is maintained by a long-term treatment with intranasal steroids.
There is insufficient evidence to recommend steroids for symptom control in infectious mononucleosis. There is a lack of research on the side effects, including potential adverse effects or long-term complications.
