Efficacy of prednisolone in children hospitalized for recurrent wheezing

Data on the efficacy of corticosteroids on respiratory picornavirus-induced wheezing are limited. To determine whether prednisolone is effective in rhinovirus- or enterovirus-induced recurrent wheezing, we conducted a controlled trial comparing oral prednisolone (2 mg/kg/day in three divided doses for 3 days) with placebo in hospitalized wheezing children and studied post hoc virus-specific efficacy in early wheezing (<3 episodes, reported elsewhere) and in recurrent wheezing (>or=3 episodes). Virus-negative children where excluded. Our primary endpoint was the time until children were ready for discharge. Secondary endpoints included oxygen saturation and exhaled nitric oxide during hospitalization, duration of symptoms, blood eosinophil count, and impulse oscillometry 2 wk after discharge, and occurrence of relapses during the following 2 months. Virus-specific effects were analyzed with interaction analysis in a multivariate regression model. During the study period, 661 patients were hospitalized, 293 randomized, and 59 were accepted in this analysis (mean age 2.6 yr, s.d. 1.3). Prednisolone did not significantly decrease the time until ready for discharge in all patients (prednisolone vs. placebo, medians, 18 vs. 24 h, p = 0.11). However, prednisolone decreased the time until ready for discharge in children with picornavirus infection (respectively, 12 vs. 24 h, p = 0.0022) and more specifically, in children with enterovirus infection (6 vs. 35 h, p = 0.0007). In the secondary endpoints, prednisolone decreased the duration of cough and dyspnea in rhinovirus-affected children (p = 0.033 for both). Prospectively designed clinical trial is needed to test the hypothesis that prednisolone reduces symptoms in picornavirus-affected wheezing children.     

Oral prednisolone is an effective adjuvant therapy for acute otitis media with discharge through tympanostomy tubes

OBJECTIVE: To determine the efficacy of a short course of oral prednisolone as an adjuvant therapy for acute otitis media draining through tympanostomy tubes. STUDY DESIGN: In a randomized, double-blind, placebo-controlled study, children with acute discharge (<48 hours) through tympanostomy tubes received either prednisolone (2 mg/kg/d; n = 23) or placebo (n = 27) for 3 days. All children received amoxicillin/clavulanate (40/10 mg/kg/d) for 7 days. The children were examined daily at the study clinic until the drainage ceased. RESULTS: The median duration of otorrhea in the prednisolone group was 1.0 days (25% to 75% range, 1.0 to 2.0 days), compared with 3.0 days (25% to 75% range, 2.0 to 4.0 days) in the children receiving placebo (P <.001). The duration of otorrhea was 相似文献   

Comparative efficacy of oral dexamethasone versus oral prednisone in acute pediatric asthma.

OBJECTIVE: The objective was to determine whether 2 days of oral dexamethasone (DEX) is more effective than 5 days of oral prednisone/prednisolone (PRED) in improving symptoms and preventing relapse in children with acute asthma. STUDY DESIGN: This was a prospective randomized trial of children (2 to 18 years old) who presented to the emergency department with acute asthma. PRED 2 mg/kg, maximum 60 mg (odd days) or DEX 0.6 mg/kg, maximum 16 mg (even days) was used. At discharge children in the PRED group were prescribed 4 daily doses (1 mg/kg/d, maximum 60 mg); children in the DEX group received a prepackaged dose (0.6 mg/kg, maximum 16 mg) to take the next day. The primary outcome was relapse within 10 days. RESULTS: When DEX was compared with PRED, relapse rates (7.4% of 272 vs 6.9% of 261), hospitalization rates from the emergency department (11% vs 12%) or after relapse (20% vs 17%), and symptom persistence at 10 days (22% vs 21%) were similar. In the PRED group more children were excluded for vomiting in the emergency department (3% vs 0.3%; P =.008), more parents were noncompliant (4% vs. 0.4%; P =.004), and more children missed > or =2 days of school (19.5% vs. 13.2%; P =.05). CONCLUSION: In children with acute asthma, 2 doses of dexamethasone provide similar efficacy with improved compliance and fewer side effects than 5 doses of prednisone.     

Long and short-term effect of prednisolone in hospitalized infants with acute bronchiolitis

OBJECTIVE: To assess long and short-term effect of prednisolone in hospitalized infants with bronchiolitis. METHODOLOGY: A randomized and controlled trial was carried out at the Federal University of Rio Grande, Rio Grande-RS, Brazil. Twenty-eight patients were randomly allocated prednisolone (1 mg/kg/day for 5 days) plus standard care, and 24 patients allocated standard care alone. The primary endpoint was the prevalence of post-bronchiolitis wheezing at 1, 3, 6 and 12 months after hospital discharge. The secondary endpoints were: length of hospital stay, duration of oxygen therapy and time to clinical improvement during the hospitalization. RESULTS: There were no significant differences between the prednisolone and control group in the prevalence of post-bronchioltis wheezing at 1 month (73.1 vs 83.3%, P = 0.5), 3 months (73.1 vs 79.2%, P = 0.7), 6 months (65.4 vs 66.7%, P = 0.9) and 12 months (50.0 vs 58.3%, P = 0.5) after hospital discharge. No reduction was observed in the prednisolone group, compared with the control group, in terms of length of hospital stay (6.0 vs 5.0 days, P = 0.7), duration of oxygen therapy (24.0 vs 24.0 h, P = 0.4) and time to clinical resolution (4.0 vs 4.0 days, P = 0.8). CONCLUSIONS: Prednisolone has no significant effect on reducing the prevalence of post-bronchiolitis wheezing and on improving the acute course of illness in hospitalized infants with bronchiolitis.     

Efficacy of nebulized budesonide compared to oral prednisolone in acute bronchial asthma

To evaluate the efficacy of nebulized budesonide compared to oral prednisolone early in the emergency room management of acute asthma, we conducted a double-blind, placebo-controlled trial. Eighty children, 2 years to 12 years of age, with acute moderate attacks of asthma, were randomized into two groups. One group received nebulized salbutamol (0.15 mg/kg) and placebo at half-hourly intervals for three doses, and a single dose of oral prednisolone (2 mg/kg) (prednisolone group) and other group received three doses of nebulized salbutamol and budesonide (800 microg) at half-hourly intervals and a single dose of placebo tablets (budesonide group). The baseline characteristics of the two groups were similar, but after three doses of nebulization oxygen saturation, respiratory rate, pulmonary index and respiratory distress score were significantly improved in the budesonide group compared to prednisolone group (p < 0.01). The proportion of patients who were fit for discharge at the end of 2 h after the third dose of nebulization was significantly higher in the budesonide group than in the prednisolone group (22/ 41, 54% vs 7/39, 18%, p < 0.001). The data suggest that a combination of nebulized salbutamol and budesonide should be preferred in the emergency room management of children with acute moderate to severe exacerbation of asthma and who are not on prior oral or inhaled steroid therapy.     

Evaluation of the efficacy of prednisolone in early wheezing induced by rhinovirus or respiratory syncytial virus

BACKGROUND: The role of systemic corticosteroids in the treatment of early childhood wheezing in children is not clear. OBJECTIVE: We sought to determine whether prednisolone is effective in rhinovirus-induced early wheezing. METHODS: We conducted a controlled trial comparing oral prednisolone (2 mg/kg per day in three divided doses for 3 days) with placebo in 78 hospitalized children (mean age, 1.1 year; standard deviation, 0.7) experiencing their first or second episode of wheezing induced by rhinovirus or respiratory syncytial virus. Mixed viral infections were excluded. Our primary end point was the time until the patient was ready for discharge; secondary end points included oxygen saturation during hospitalization, duration of symptoms, occurrence of relapses during the next 2 months and blood eosinophil counts at discharge and 2 weeks later. RESULTS: In multivariate regression analysis, prednisolone did not influence the time until ready for discharge, but it decreased relapses during the subsequent 2-month period in rhinovirus-affected children (prednisolone versus placebo, 22% versus 56%; odds ratio, 19.06; 95% confidence interval, 2.52-144.03; P = 0.004) and in children with blood eosinophils > or = 0.2 x 10/L (respectively, 24% versus 71%; odds ratio, 10.57; 95% confidence interval, 1.99-56.22; P = 0.006). Rhinovirus-affected children had more blood eosinophils on admission (mean, 0.44 versus 0.086 x 10/L), had a higher prevalence of atopy (44% versus 8%) and were older (mean, 1.4 versus 0.9 years, P < 0.001 for all) than respiratory syncytial virus-infected children. CONCLUSION: Prednisolone reduced relapses during a 2-month period after first episodes of wheezing associated with rhinovirus infection or blood eosinophils > or = 0.2 x 10/L.     

Placebo controlled trial of systemic corticosteroids in acute childhood asthma

In a randomised controlled trial 38 asthmatic children aged 2-11 yr who had not received regular oral or inhaled steroids during the previous year, were treated with a standard regime of nebulised salbutamol and intravenous aminophylline plus either hydrocortisone and oral prednisolone for 5 days, or placebo. The children were observed throughout their hospital stay and for 3 months afterwards. There was a greater fall in heart rates in the steroid treated group on the second day of treatment (mean diff. 16 beats/min) and at discharge (mean diff. 13 beats/min); p less than 0.025. Peak Expiratory Flow Rates recorded in 26 children, 13 in each group, showed more improvement on day 2 in those given steroids (mean diff 16% predicted); p less than 0.05. This difference was not apparent at discharge but 9 children treated with steroids were clinically wheeze-free when they left hospital compared with 3 in the placebo group, p less than 0.05. There were no differences in respiratory rate, pulsus paradoxus and arterial oxygen saturation. Trends in duration of hospital stay and relapse rate during the succeeding 3 months favoured active treatment. These findings support the use of systemic corticosteroids in addition to high dose bronchodilators to treat 'non steroid dependent' children hospitalised with acute severe asthma.     

Respiratory syncytial virus (RSV) immune globulin intravenous therapy for RSV lower respiratory tract infection in infants and young children at high risk for severe RSV infections: Respiratory Syncytial Virus Immune Globulin Study Group

OBJECTIVES: To evaluate the efficacy of high-titer intravenous respiratory syncytial virus immune globulin (RSVIG) in the treatment of children at high risk for severe RSV infection who were hospitalized with proven RSV. METHODS: Infants and young children younger than 2 years with bronchopulmonary dysplasia, chronic lung disease, congenital heart disease, or prematurity (<32 weeks' gestational age), hospitalized with a history of lower respiratory tract infection (LRI) of less than 4 days, were enrolled in this study. Patients were randomized in a blinded fashion to receive either 1500 mg/kg RSVIG or placebo in equal volumes. They were evaluated daily for safety and respiratory scores and for RSV nasal shedding. RESULTS: One hundred seven high-risk children were randomized--54 in the RSVIG group and 53 in the placebo group. Of these children, 51 in each group were considered evaluable. Children with pulmonary disease, congenital heart disease, or prematurity were equally distributed between the two treatment groups. However, two important differences were found in baseline variables between the two groups: there were more patients in the placebo group who had histories of previous LRI and there was a trend toward more severe disease at study entry in the RSVIG group. This was manifested by a higher entry respiratory score in the RSVIG group than in the placebo group (3.4 +/- 0.2 vs 3.1 +/- .01). A higher proportion of children in the RSVIG group (47%) than in the placebo group (28%) required intensive care at entry and mechanical ventilation at study entry (31% RSVIG-treated vs 18% placebo-treated patients). No significant difference was found between groups in the mean unadjusted duration of hospitalization (RSVIG group, 9.10 +/- 1.18 days; control group, 8.17 +/- 1.08 days). When the mean was adjusted for entry respiratory score, likewise, no difference was observed between each group (8.41 +/- 0.97 vs 8.89 +/- .99 days). The lack of efficacy observed in the study primary endpoint was observed in all diagnostic groups. No differences between the RSVIG and placebo groups were observed in the following secondary endpoints: duration of intensive care unit stay, duration of intensive care unit stay for RSV, mechanical ventilation, or supplemental oxygen. No significant differences in adverse events were reported in the RSVIG group (16 children) when compared with the control group (10 children). CONCLUSION: RSVIG treatment was safe but not efficacious in the treatment of children with bronchopulmonary dysplasia, congenital heart disease, or premature gestation who were hospitalized with RSV LRI.     

Placebo Controlled Trial of Systemic Corticosteroids in Acute Childhood Asthma

ABSTRACT. In a randomised controlled trial 38 asthmatic children aged 2-11 yr who had not received regular oral or inhaled steroids during the previous year, were treated with a standard regime of nebulised salbutamol and intravenous aminophylline plus either hydrocortisone and oral prednisolone for 5 days, or placebo. The children were observed throughout their hospital stay and for 3 months afterwards. There was a greater fall in heart rates in the steroid treated group on the second day of treatment (mean diff. 16 beats/min) and at discharge (mean diff. 13 beats/min); p < 0.025. Peak Expiratory Flow Rates recorded in 26 children, 13 in each group, showed more improvement on day 2 in those given steroids (mean diff 16% predicted); p < 0.05. This difference was not apparent at discharge but 9 children treated with steroids were clinically wheeze-free when they left hospital compared with 3 in the placebo group, p < 0.05. There were no differences in respiratory rate, pulsus paradoxus and arterial oxygen saturation. Trends in duration of hospital stay and relapse rate during the succeeding 3 months favoured active treatment. These findings support the use of systemic corticosteroids in addition to high dose bronchodilators to treat 'non steroid dependent' children hospitalised with acute severe asthma.     

Palivizumab prophylaxis reduces hospitalization due to respiratory syncytial virus in young children with hemodynamically significant congenital heart disease

OBJECTIVES: To evaluate the safety, tolerance, and efficacy of palivizumab in children with hemodynamically significant congenital heart disease (CHD). STUDY DESIGN: A randomized, double-blind, placebo-controlled trial included 1287 children with CHD randomly assigned 1:1 to receive 5 monthly intramuscular injections of 15 mg/kg palivizumab or placebo. Children were followed for 150 days. The primary efficacy end point was antigen-confirmed respiratory syncytial virus (RSV) hospitalization. RESULTS: Palivizumab recipients had a 45% relative reduction in RSV hospitalizations (P=.003), a 56% reduction in total days of RSV hospitalization per 100 children (P=.003), and a 73% reduction in total RSV hospital days with increased supplemental oxygen per 100 children (P=.014). Adverse events were similar in the treatment groups; no child had drug discontinued for a related adverse event. Serious adverse events occurred in 55.4% of palivizumab recipients and 63.1% of placebo recipients (P<.005); none were related to palivizumab. Twenty-one children (3.3%) in the palivizumab group and 27 (4.2%) in the placebo group died; no deaths were attributed to palivizumab. The rates of cardiac surgeries performed earlier than planned were similar in the treatment groups. CONCLUSIONS: Monthly palivizumab (15 mg/kg IM) was safe, well-tolerated, and effective for prophylaxis of serious RSV disease in young children with hemodynamically significant CHD.     

A DOUBLE BLIND TRIAL OF PREDNISOLONE IN EPIDEMIC BRONCHIOLITIS DUE TO RESPIRATORY SYNCYTIAL VIRUS

A double blind trial of prednisolone treatment was carried out on 95 children with clinical evidence of epidemic bronchiolitis. The trial showed that there was no difference between the prednisoIone and the placebo group in the duration of symptoms and signs. Eighty-four per cent of children were shown to be infected with respiratory syncytial virus. Prednisolone in the dosage used did not affect the antibody response to infection. The presence of maternal antibody to respiratory syncytial virus, while not preventing infection, reduced the number of active antibody responses in children aged 3 months or younger. Eight children had a double infection with respiratory syncytial virus and adenovirus which lengthened their average stay in hospital by two days and the overall duration of illness by more than three days.     

Efficacy of oral dexamethasone in outpatients with acute bronchiolitis

OBJECTIVE: To examine the efficacy of oral dexamethasone in acute bronchiolitis. STUDY DESIGN: A double-blind randomized, placebo-controlled trial involving 70 children < 24 months old in the emergency department with Respiratory Disease Assessment Instrument > or = 6. Each patient received either 1 dose of 1 mg/kg of oral dexamethasone or placebo and was assessed hourly for a 4-hour period. Repeated measures regression analysis evaluated a change in the Respiratory Assessment Change Score (RACS). RESULTS: The 2 groups had similar baseline characteristics with Respiratory Disease Assessment Inventory of 9.4 +/- 2.3 in the dexamethasone group (n = 36) and 10.0 +/- 2.7 in the placebo group (n = 34). The RACS was -5.0 +/- 3.1 in the dexamethasone group and -3.2 +/- 3.7 in the placebo group (P =.029). Poor RACS occurred in 41% and 17% of the placebo and dexamethasone groups, respectively (P =.034). Of the children treated with dexamethasone, 19% were hospitalized compared with 44% in the placebo group (P =.039). There was no difference in RACS between the groups on day 7 (P =.75). CONCLUSION: Outpatients with moderate-to-severe acute bronchiolitis derive significant clinical and hospitalization benefit from oral dexamethasone treatment in the initial 4 hours of therapy.     

Respiratory syncytial virus immune globulin treatment of RSV lower respiratory tract infection in previously healthy children

OBJECTIVE: To evaluate the efficacy of high titer respiratory syncytial virus (RSV) immune globulin (RSVIG) in the treatment of previously healthy children hospitalized with proven RSV lower tract infection (LRI). METHOD: Infants and young children /=2. 5 were enrolled. RESULTS: One hundred and one previously healthy children hospitalized with RSV LRI received either 1500 mg/kg of RSVIG (RespiGam, MedImmune Inc, Gaithersburg, MD) or albumin placebo in a randomized, double-blind, placebo-controlled trial. Forty-six RSVIG and 52 recipients of placebo met all eligibility criteria. Demographic characteristics of the two groups were similar. More RSVIG recipients (46% vs 29%) had an SaO2 /=3.0) had 1.6 fewer hospital days and 2.7 days less ICU stays. CONCLUSION: RSVIG infusions seemed safe and generally well tolerated. Although some beneficial effect trends were seen for those with more severe disease who were treated there was no evidence that treatment with RSVIG resulted in reduced hospitalization and reduced ICU stays in all children with RSV disease.     

Effect of probiotic Lactobacillus strains in young children hospitalized with acute diarrhea

BACKGROUND: Oral bacteriotherapy promotes recovery from acute childhood diarrhea, but few strains have been shown to have therapeutic potentials. We examined the effect of two newly identified probiotic Lactobacillus strains in acute childhood diarrhea. METHODS: Sixty-nine children were randomized during hospitalization for acute diarrhea to receive a mixture of Lactobacillus rhamnosus 19070-2 and Lactobacillus reuteri DSM 12246, 10(10) colony-forming units of each strain or placebo twice daily for 5 days. Before selection of these stains their potential probiotic characteristics were demonstrated in vitro and in healthy volunteers. RESULTS: In patients receiving probiotics, the diarrheal phase was reduced by 20%. The duration of diarrhea was 82 h in the treatment group vs. 101 h in the control group (not significant, P = 0.07). However, 3 of 30 patients from the treatment group vs. 13 of 39 from the control group still had loose stools at the end of the study period (P = 0.03). In patients with diarrhea for <60 h before start of treatment (early intervention), a clear effect of the probiotics was demonstrated (80 h in the treatment group vs. 130 h in the control group, P = 0.003). After early intervention, the length of hospitalization was reduced by 48% (3.5 vs. 1.7 days, P = 0.03). At the end of the intervention, rotavirus antigen was found in 12% of patients from the treatment group vs. 46% from the control group (P = 0.02). CONCLUSIONS: The two probiotics, L. rhamnosus 19070-2 and L. reuteri DSM 12246, ameliorated acute diarrhea in hospitalized children and reduced the period of rotavirus excretion. Oral bacteriotherapy was associated with a reduced length of hospital stay. The beneficial effects were most prominent in children treated early in the diarrheal phase.     

Aggressive management of dengue shock syndrome may decrease mortality rate: a suggested protocol.

OBJECTIVES: Dengue shock syndrome is a leading cause of mortality among Indian children. In January 2000, we instituted a protocol for aggressive management of children with dengue shock syndrome. The objective of this study was to compare outcomes (duration of ventilation, pediatric intensive care unit stay, incidence of acute respiratory distress syndrome, and intensive care unit and hospital mortality) before and after the protocol. DESIGN: Retrospective chart review. SETTING: Pediatric intensive care unit at a tertiary teaching hospital. PATIENTS: One hundred and fourteen patients admitted between July 1997 and December 1999 received standard therapy recommended by the World Health Organization (WHO) and were designated as the WHO guidelines group (W), whereas 96 patients admitted between January 2000 and December 2001 were treated by our protocol and designated as the protocol group (P). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The patients in each group were equally matched in terms of age, Pediatric Risk of Mortality, and number with dengue hemorrhage fever grade IV, although the platelet counts were higher in the W group compared with the P group (geometric mean 42.2, confidence interval 36.9, 48.4 vs. geometric mean 36.7, confidence interval 33.3, 40.5, p < .05). Patients in the W group received less fluids in the first hour compared with the P group (median and interquartile range 20 mL/kg, 15 and 20 vs. 30 mL/kg, 20 and 60). Fluid was actively removed less often in the W group than the P group (6 of 111 vs. 45 of 96, p < .05). There was no difference in the need for ventilation or incidence of acute respiratory distress syndrome between groups, although among dengue hemorrhage fever grade IV patients, the number requiring ventilation (17 of 30 vs. 20 of 23, p < .05) and the incidence of acute respiratory distress syndrome (9 of 30 vs. 17 of 23, p < .05) were significantly greater in the W group compared with the P group. The duration of ventilation (1.5 +/- 1.7 vs. 4.2 +/- 2.9 days, p < .05) and length of intensive care unit stay (3.0 +/- 2.8 vs. 3.4 +/- 2.9 days, p < .05) were significantly less in the W group. The pediatric intensive care unit mortality (16.6% vs. 6.3%, p < .05) was significantly higher in the W group than in the P group. CONCLUSIONS: Patients with dengue shock syndrome are at high risk of mortality due to refractory shock and multiple organ failure. Survival was better for patients in the P group. Aggressive shock management and possibly the use of judicious fluid removal may decrease mortality rates in the severest forms of dengue shock syndrome.     

Inhaled budesonide in acute asthma

OBJECTIVE: To evaluate the efficacy of aerosolized budesonide therapy (with metered dose inhaler and spacer) early in the emergency room treatment of acute moderate exacerbations of bronchial asthma in children. DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Paediatric Emergency Service of an urban teaching hospital and a tertiary case referral centre. STUDY POPULATION: Sixty children between 3 and 12 years of age with an acute moderate exacerbation of asthma. INTERVENTION: All patients received humidified oxygen (5-8 L/min by Venturi(R) mask; Hudson Respiratory Care, Temecula, CA, USA), nebulized salbutamol (0.15 mg/kg in 3 mL saline) and were randomized to receive either budesonide (400 microg) or placebo inhalation (MDI and spacer) at half hourly intervals for three doses. If there was an inadequate response or no response to treatment at the end of 2 h, oxygen and salbutamol therapy were continued and the patient was given one of dose intravenous hydrocortisone and was started on an aminophylline infusion. If there was no response at the end of a further 4 h, the patient was hospitalized. INITIAL EVALUATION AND MONITORING: Colour, respiratory rate (RR), heart rate, accessory muscle usage, chest retraction, wheeze, oxygen saturation (by pulse oximetery) and peak expiratory flow rate (PEFR) was recorded at admission and thereafter at hourly intervals for 3 h or until till the child recovered. The need for oxygen therapy after 2 h and need for hospitalization were recorded. MAIN RESULTS: Both groups showed a significant improvement in respiratory status at the end of 2 h. However, children in the intervention group showed greater improvements in RR and PEFR (P < 0. 05) and respiratory distress score (P < 0.1). A significantly lower proportion of the intervention group patients required oxygen therapy for more than 2 h (23% vs 50%; P < 0.05) and aminophylline infusion and systemic corticosteroid therapy (7% vs 27%; P < 0.05). None of the children in the budesonide group, in contrast to 23% of those in the placebo group, required hospitalization (P < 0.05). The length of hospital stay (i.e. time taken to recover from acute asthma) was significantly shorter in the intervention group (3.2 +/- 2.5 h) than in the placebo group (7.8 +/- 11.3 h; P < 0.01). CONCLUSION: Aerosolized budesonide therapy (with MDI and spacer) together with nebulized salbutamol early in the emergency room treatment of acute moderate exacerbations of asthma helped in early recovery and decreased the need for hospitalization. It may be worthwhile calculating this regimen for home-based early treatment of acute exacerbations.

Outcome of ventricular septal defect repair in a developing country

OBJECTIVES: To examine the impact of nutrition and lung infection on outcome early after ventricular septal defect (VSD) repair in infants in a developing country. STUDY DESIGN: One hundred consecutive infants (age, 7.4 +/- 3.3 months) with large VSD(s) who underwent surgical repair at one institution in South India from July 1998 to June 2000 were analyzed. Primary outcome variables were postoperative death, duration of mechanical ventilation, intensive care unit (ICU) stay, and hospital stay. Preoperative variables analyzed included age, weight and length Z scores, and lung infection. RESULTS: Preoperative nutrition was poor (weight Z score, -2.8 +/- 1.3), and 25 patients had pneumonia. Six patients died after repair. No preoperative variable was associated with death. Mechanical ventilation, ICU stay, and hospital stay were longer for younger patients (r (s) for ventilation, -0.23, P =.02; for ICU stay, -0.33, P <.001; for hospital stay, -0.27, P =.007) and for those with preoperative pneumonia (median ventilation duration, 46 vs 24 hours, P <.001; median ICU stay 7 vs 4 days, P <.001; median hospital stay 10 vs 7 days, P =.001). Preoperative weight and length Z scores were not associated with any outcome variable. CONCLUSIONS: Poor nutritional status, preoperative pneumonia, and age do not increase mortality rates after VSD repair. Repair of large VSDs should not be delayed because of these preoperative characteristics.     

A randomized, placebo-controlled trial of the effect of antihistamine or corticosteroid treatment in acute otitis media

OBJECTIVES: To determine whether the adjunctive drugs antihistamine and corticosteroid improve immediate and long-term outcomes of acute otitis media (AOM). STUDY DESIGN: Children with AOM (3 mos-6 y) were enrolled in a randomized, double-blind, placebo-controlled trial. All 179 children received one dose of intramuscular ceftriaxone and were assigned to receive either chlorpheniramine maleate (0.35 mg/kg/d) and/or prednisolone (2 mg/kg/day) or placebo for 5 days. Main outcome measures were rate of treatment failure during the first 2 weeks, duration of middle ear effusion, and rate of recurrences of AOM to 6 months. RESULTS: Clinical outcomes and recurrence rates did not differ significantly with treatment. Children who received antihistamine alone had significantly longer duration of middle ear effusion (median, 73 days) than subjects in other treatment groups (median, 23 to 36 days, P=.04). Temporary normalization of tympanometric findings on day 5 occurred more frequently in the corticosteroid-treated group (P=.04). CONCLUSIONS: Five-day treatment with antihistamine or corticosteroid, in addition to antibiotic, did not improve AOM outcomes. Antihistamine use during an acute episode of OM should be avoided, since the drug may prolong the duration of middle ear effusion. The efficacy of 7- to 10-day treatment of AOM with corticosteroid, in addition to antibiotic, deserves further investigation.
