Input: We included two studies involving 252 children with AOM aged from three months to six years receiving hospital ambulatory care who were treated with intramuscular ceftriaxone, and who were then randomised to the corticosteroid group (corticosteroid and corticosteroid plus antihistamine) or the placebo group (antihistamine and double placebo). In one study, children also had a needle aspiration of middle ear fluid. Both studies were at unclear risk of bias for allocation concealment, and unclear to high risk of bias for selective reporting. One study (N = 179) included pain as an outcome, but we were unable to derive the proportion of children with persistent pain at Day 5 and Day 14. Reduction of overall or specific symptoms was presented as improvement in clinical symptoms and resolution of inflamed tympanic membranes without the need for additional antibiotic treatment: at Day 5 (94% of children in the treatment group (N = 89) versus 89% in the placebo group (N = 90); risk ratio (RR) 1.06, 95% confidence interval (CI) 0.97 to 1.16) and Day 14 (91% versus 87%; RR 1.05, 95% CI 0.95 to 1.17). Low-quality evidence meant that we are uncertain of the effectiveness of corticosteroids for this outcome. The second study (N = 73) reported a reduction of overall or specific symptoms without additional antibiotic treatment during the first two weeks as a favourable outcome. Children in the treatment group had more favourable outcomes (adjusted odds ratio 65.9, 95% CI 1.28 to 1000; P = 0.037), although the numbers were small. We were unable to pool the results with the other study because it did not report the proportion of children with this outcome by treatment group. Only one study reported adverse effects of corticosteroids (e.g. drowsiness, nappy rash), but did not quantify incidence, so we were unable to draw conclusions about adverse effects. Neither study reported a reduction in overall or specific symptom duration. The evidence for the effect of systemic corticosteroids on AOM is of low to very low quality, meaning the effect of systemic corticosteroids on important clinical outcomes in AOM remains uncertain. Large, high-quality studies are required to resolve the question.
Output:

We included two studies involving 252 children with AOM, aged from three months to six years, receiving hospital ambulatory care. Children were treated with an antibiotic injection and either oral corticosteroid or a placebo (treatment with no effect). In one study, fluid from the middle ear was collected by inserting a needle through the eardrum to measure the level of inflammation. The National Institutes of Health (NIH) and the National Center for Research Resources, NIH, US Public Health Service funded both studies. Pharmaceutical companies provided the drug but did not contribute any other scientific or financial support. Corticosteroids did not make a significant difference in improving the symptoms and inflammation of the eardrum(s) at Day 5 and Day 14, but we are unsure of this effect due to the small numbers of children in the studies. There were no significant differences between the corticosteroid and placebo groups in terms of resolving fluid in children's middle ears (at 1, 2, and 3 months) and experiencing new episodes of AOM (at 1, 2, 3 months, and 4 and 6 months). Neither study reported a reduction in the duration of overall or specific symptoms, rupture of eardrum(s), the occurrence of middle ear inflammation in the other ear following the current ear infection, or serious complications. Only one study reported the overall side effects identified during the trial (e.g. drowsiness, dry mouth, diaper rash, nervousness). We could not draw any conclusions regarding the effects of corticosteroids for AOM in children. The quality of evidence included in this review was low to very low due to few children included in two small studies. We are uncertain about whether or not corticosteroids are useful in relieving pain from AOM.
