To determine the effectiveness of a single dose of oral dexamethasone in reducing the pain associated with moderate to severe pharyngitis in pediatric patients.
                Prospective, randomized, double-blind, placebo-controlled clinical trial.
                Large, urban pediatric emergency department between March 2002 and November 2003.
                Children aged 5 to 18 years with moderate to severe pharyngitis (odynophagia or dysphagia, moderate to severe pharyngeal erythema or swelling, and a McGrath Facial Affective Scale score of 0.75 or higher [scale 0.0-1.0]).
                Study patients were randomly assigned to receive 1 dose of either oral dexamethasone suspension (0.6 mg/kg with a maximum of 10 mg) or placebo of the same volume. All participants were tested for group A beta-hemolytic streptococcal pharyngitis and treated accordingly. Daily telephone follow-up was conducted until complete resolution of sore throat.
                Primary outcome variables included hours to initial relief of sore throat and time to the complete resolution of pain. Secondary outcome variables included changes in the McGrath Facial Affective Scale score at 24 and 48 hours, persistence of associated symptoms, use of anti-inflammatory or antipyretic medication, and subsequent use of medical resources for dehydration or pain.
                A convenience sample of 150 patients was randomized to receive either dexamethasone (n = 75) or placebo (n = 75). Twenty-five patients were lost to follow-up, leaving 125 patients available for data analysis; 57 received dexamethasone and 68 received placebo. Patients who received dexamethasone reported earlier onset of pain relief (9.2 vs 18.2 hours; P<.001), fewer hours to complete resolution of sore throat (30.3 vs 43.8 hours; P = .04), and larger changes in the McGrath Facial Affective Scale score in the first 24 hours (-0.58 vs -0.43; P = .002). Children who tested negative for group A beta-hemolytic streptococci had greater pain relief with dexamethasone compared with placebo (onset of pain relief, 8.7 vs 24 hours; P = .001), less time to complete resolution of sore throat (37.9 vs 70.8 hours; P = .006), and greater changes in the McGrath Facial Affective Scale score in the first 24 hours (-0.50 vs -0.21; P<.001).
                Children with moderate to severe pharyngitis had earlier onset of pain relief and shorter duration of sore throat when given oral dexamethasone. We compare oral dexamethasone with placebo for the relief of pain in children with acute pharyngitis.
                We performed a prospective, randomized, double-blind, placebo-controlled trial of children aged 5 to 16 years who presented to the emergency department with acute pharyngitis. Children rated their pain on a standardized color analog scale and had a rapid streptococcal antigen detection test performed to determine group assignment. Children were randomized to dexamethasone (0.6 mg/kg, maximum dose 10 mg) or placebo. Blinded research assistants called all families daily to determine pain scores until the point of complete pain relief. The primary outcome measures were the time to clinically significant pain relief and the time to complete pain relief.
                A total of 184 children were enrolled in the study. There were 85 children in the antigen-positive group, of whom 45 were randomized to dexamethasone and 40 to placebo. In children with group A beta-hemolytic streptococcal pharyngitis, the median time to clinically significant pain relief was 6 hours in the dexamethasone group versus 11.5 hours in the placebo group (P =.02; effect size of 5.5 hours with 95% confidence interval [CI] of 1.0 and 10.0 hours), and the time to complete pain relief was similar (36 hours for placebo versus 40 hours for dexamethasone, P =.86; effect size of 4.0 hours with 95% CI of -9.3 and 17.3 hours) in the placebo group. There were 99 children enrolled in the antigen-negative group, of whom 47 received dexamethasone and 52 received placebo. In this group, the median time to clinically significant pain relief was 13 hours in the dexamethasone group versus 9 hours in the placebo group (P =.32; effect size of 4 hours with 95% CI of -2 and 10 hours), and the time to complete pain relief was similar (48 hours for placebo versus 50 hours for dexamethasone, P =.61; effect size of 2 hours with 95% CI of -11.8 and 15.8 hours).
                For all children with acute pharyngitis, oral dexamethasone does not decrease the time to onset of clinically significant pain relief or time to complete pain relief. However, in the subset of children with positive antigen detection test results, there is a statistically significant improvement in time to onset of pain relief, but it is of marginal clinical importance. Pharyngeal inflammatory pain is reduced by a single dose of dexamethasone.
                Prospective, randomized, double-blinded, placebo-controlled study.
                From August 1998 to July 2000, a total of 118 patients were enrolled. We compared placebo (n = 37), a 10-mg single dose of intramuscular injection of dexamethasone (n = 39), and a 10-mg single dose of oral dexamethasone (n = 42). All patients were given oral antibiotics and had bacterial throat cultures.
                Complete telephone follow-up 12 hours after treatment was available in 111 patients, and 24-hour follow-up data were available in 116. The change in pain visual analogue scale scores (pretreatment score minus 12-h follow-up score) reported by patients who were given either intramuscular (median score, 4; mean score +/- SD, 4.2 +/- 2.3) or oral dexamethasone (median score, 3; mean score +/- SD, 3.8 +/- 2.3) was significantly greater than that of the patients who were given placebo (median score, 2; mean score +/- SD, 2.1 +/- 2.0) (P <.001 and P =.002, respectively). This difference in improvement was also evident when the percentage of change was compared in the three treatment arms at 12-hour and 24-hour follow-up. Patients who were given dexamethasone had the onset of pain relief a median of 4 hours earlier than those who were given oral and intramuscular placebo (P =.029). Statistically significant differences among the three treatment arms were confirmed when a bacterial pathogen was identified (n = 47) but not in a subset that did not have a pathogen identified.
                Single-dose dexamethasone appears to be a safe, effective, and inexpensive adjunctive treatment for acute pharyngitis in patients 15 years of age and older. Patients treated with intramuscular or oral dexamethasone had significant relief of pain (relative to baseline) compared with patients who were given placebo. Identification of a bacterial pathogen had a significant impact on the response to dexamethasone. The objective of this study was to investigate whether treatment with single-dose dexamethasone can provide relief of symptoms in acute exudative pharyngitis. A prospective, randomized, double-blinded, placebo-controlled clinical trial was undertaken over a 3-month period in a university-based Emergency Department. The study included all consecutive patients between 18 and 65 years of age presenting with acute exudative pharyngitis, sore throat, odynophagia, or a combination, and with more than two Centor criteria. Each patient was empirically treated with azithromycin and paracetamol for 3 days. The effects of placebo and a fixed single dose (8 mg) of intramuscular injection of dexamethasone were compared. The patients were asked to report the exact time to onset of pain relief and time to complete relief of pain. After completion of the treatment, telephone follow-up regarding the relief of pain was conducted. A total of 103 patients were enrolled. Thirty patients with a history of recent antibiotic use, pregnancy, those who were elderly (>65 years of age) and patients who failed to give informed consent were excluded. Forty-two patients were assigned to the placebo group and 31 were assigned to the intramuscular dexamethasone group (8-mg single dose). Time to perceived onset of pain relief was 8.06+/-4.86 h in steroid-treated patients, as opposed to 19.90+/-9.39 h in the control group (p=0.000). The interval required to become pain-free was 28.97+/-12.00 h in the dexamethasone group, vs. 53.74+/-16.23 h in the placebo group (p=0.000). No significant difference was observed in vital signs between the regimens. No side effects and no new complaints attributable to the dexamethasone and azithromycin were observed. Sore throat and odynophagia in patients with acute exudative pharyngitis may respond better to treatment with an 8-mg single dose of intramuscular dexamethasone accompanied by an antibiotic regimen than to antibiotics alone. Studies in adults, but not in children, have shown a beneficial effect of one dose of steroid on the severity and duration of throat pain in acute pharyngitis. The effectiveness of longer steroid treatment has not been evaluated in children.
                We performed a randomized, double-blind, 3-arm, placebo-controlled trial to estimate the effectiveness of one dose versus 3 daily doses of oral dexamethasone in the treatment of 4- to 21-year-old patients with group A beta-hemolytic streptococcal (GABHS) pharyngitis. Participants used the Wong-Baker FACES scale to rate their symptoms at enrollment and twice daily for 5 days. Patient-completed diaries and telephone interviews provided follow-up data. Primary end points-severity of throat pain, improvement in general condition and improvement in activity level-were evaluated by survival analysis.
                Ninety patients were enrolled. For each end point, we rejected the null hypothesis of a common survival experience for the 3 study arms. With the exception of 2 days for throat pain in participants receiving one dose of dexamethasone, the median time to improvement for all end points was 1 day for both arms of dexamethasone and 2 days for placebo. There was no difference between study arms in return to a clinical setting for symptoms related to GABHS pharyngitis or absenteeism from work/school. No patient experienced complications related to GABHS pharyngitis in the 30 days after enrollment.
                In this pilot study, children with GABHS pharyngitis who receive dexamethasone as add-on therapy have a more rapid improvement in general condition and level of activity and, for those receiving 3 daily doses of dexamethasone, in resolution of throat pain. To compare betamethasone with placebo as an adjuvant to antibiotic therapy in the treatment of acute exudative pharyngitis.
                The study was a randomized, doubled-blind, placebo-controlled, single-center, parallel, outpatient clinical trial. After consent was obtained, each patient was asked to rate his or her pain on a 10-cm numbered visual analog scale (VAS; 0-10). All of the patients received injectable benzathine penicillin. If allergic to penicillin, they were started on a 10-day course of polyenteric-coated erythromycin (PCE). Each patient was randomized to receive either i.m. betamethasone or i.m. placebo. All patients were contacted by telephone at 24 and 48 hours by one of the study investigators and asked to rate their pain based on another VAS. If their pain was not resolved by 48 hours, they were called again daily between the third and seventh days after the initial visit to determine the time of pain resolution.
                A total of 92 patients were enrolled in the study, with 46 randomized to receive placebo and 46 to receive betamethasone. Eight patients were excluded from the statistical analysis because of inability to obtain follow-up. Demographic comparison showed that gender distributions, ages, mean initial pain scores, mean times to the first and second follow-up calls, and treatment regimens were similar in the 2 groups. There were significantly better pain scores for the betamethasone group at first follow-up (p = 0.0005), at second follow-up (p = 0.004), and in number of hours until relief of pain (p = 0.004). When only those patients with a positive culture for a streptococcus species were analyzed, there also were significant reductions in pain score at the first (p = 0.006) and second (p = 0.02) follow-up visits.
                Pain relief was greater and more rapid in patients treated with betamethasone as an adjuvant therapy in acute exudative pharyngitis. Acute pharyngitis is a frequent and well-documented complaint in general practice but the associated suffering has remained largely unaddressed in the literature. Evidence, however, from five randomised controlled trials suggests that corticosteroids may be useful in relieving pain and discomfort arising from the condition.
                To determine if short-acting oral therapy with prednisone was more effective than placebo in alleviating the suffering from acute pharyngitis in adults in a general practice setting.
                Randomised placebo-controlled trial.
                General practice in Israel.
                Patients with acute pharyngitis were randomised to receive 60 mg prednisone orally for 1 or 2 days, or identical placebo treatment. The main outcome measures were throat pain, measured by a visual analogue scale at 12, 24, 48 and 72 hours after presentation, time off work, fever, dysphagia, recurrence of symptoms and bacterial recurrence.
                Patients treated with prednisone experienced more rapid throat pain resolution than those in the placebo group. No adverse effects were reported nor any differences between the two groups regarding either symptom or positive bacterial culture recurrence.
                Short-acting oral steroid therapy is effective for shortening throat pain duration in acute pharyngitis. To determine the efficacy of dexamethasone as adjuvant therapy to improve pain relief in patients with severe, acute exudative pharyngitis.
                Prospective, randomized, double-blinded, placebo-controlled clinical trial.
                Large, urban community hospital emergency department with an emergency medicine residency program.
                Patients aged 12 to 65 years old with exudative pharyngitis and severe dysphagia/odynophagia. Patients with cancer, AIDS, diabetes mellitus, recent steroid use, pregnancy, or suspicion of peritonsillar abscess were excluded.
                All patients received oral penicillin (500 mg Pen VK) or erythromycin (333 mg base) three times daily for ten days in addition to either 10 mg single-dose dexamethasone or saline placebo IM injection.
                Fifty-eight patients graded their initial degree of throat pain on a visual-analog scale that was 15 cm long and scored from 0 to 3.0 in 0.5-cm increments. Follow-up was obtained on 51 patients to determine their condition at 24 hours. At entry, there was no difference in age, weight, antibiotic assignment, or initial pain score between groups. Improvement in pain score (initial versus 24 hours) was 1.8 +/- 0.8 in the 26 patients of the dexamethasone group and 1.2 +/- 0.9 in the 25 patients of the placebo group (P < .05). Time to onset of pain relief was also faster in steroid-treated patients who demonstrated relief beginning at 6.3 +/- 5.3 hours, compared with 12.4 +/- 8.5 hours in the placebo group (P < .01). Of the 26 patients evaluated at seven days (13 in each group), time to complete lack of pain averaged 15.0 +/- 11.4 hours in the dexamethasone group and 35.4 +/- 17.9 hours in the placebo group (P < .02). Complications attributable to dexamethasone were not observed.
                In patients with severe, acute exudative pharyngitis, single-injection dexamethasone adjuvant compared with placebo resulted in statistically and clinically significant improvement, as evidenced by more rapid onset and greater degree of pain relief.
Oral or intramuscular corticosteroids, in addition to antibiotics, increase the likelihood of both resolution and improvement of pain in participants with sore throat. Further trials assessing corticosteroids in the absence of antibiotics and in children are warranted.
