Abstract
OBJECTIVE Adverse events (AEs) associated with short-term corticosteroid use for respiratory conditions in young children. DESIGN Systematic review of primary studies. DATA SOURCES Medline, Cochrane CENTRAL, Embase and regulatory agencies were searched September 2014; search was updated in 2017. ELIGIBILITY CRITERIA Children <6 years with acute respiratory condition, given inhaled (high-dose) or systemic corticosteroids up to 14 days. DATA EXTRACTION AND SYNTHESIS One reviewer extracted with another reviewer verifying data. Study selection and methodological quality (McHarm scale) involved duplicate independent reviews. We extracted AEs reported by study authors and used a categorisation model by organ systems. Meta-analyses used Peto ORs (pORs) and DerSimonian Laird inverse variance method utilising Mantel-Haenszel Q statistic, with 95% CI. Subgroup analyses were conducted for respiratory condition and dose. RESULTS Eighty-five studies (11 505 children) were included; 68 were randomised trials. Methodological quality was poor overall due to lack of assessment and inadequate reporting of AEs. Meta-analysis (six studies; n=1373) found fewer cases of vomiting comparing oral dexamethasone with prednisone (pOR 0.29, 95% CI 0.17 to 0.48; I2=0%). The mean difference in change-from-baseline height after one year between inhaled corticosteroid and placebo was 0.10 cm (two studies, n=268; 95% CI -0.47 to 0.67). Results from five studies with heterogeneous interventions, comparators and measurements were not pooled; one study found a smaller mean change in height z-score with recurrent high-dose inhaled fluticasone over one year. No significant differences were found comparing systemic or inhaled corticosteroid with placebo, or between corticosteroids, for other AEs; CIs around estimates were often wide, due to small samples and few events. CONCLUSIONS Evidence suggests that short-term high-dose inhaled or systemic corticosteroids use is not associated with an increase in AEs across organ systems. Uncertainties remain, particularly for recurrent use and growth outcomes, due to low study quality, poor reporting and imprecision.

Abstract
BACKGROUND/AIMS To assess the relationship between bone and vascular disease and its changes over time after renal transplantation. Metabolic bone disease (MBD) is common in chronic kidney disease (CKD) and is associated with cardiovascular (CV) disease. Following transplantation (Tx), improvement in CV disease has been reported; however, data regarding changes in bone disease remain controversial. METHODS Bone turnover and arterial stiffness (pulse wave velocity (PWV)) were assessed in 47 Tx patients (38 (3-191) months after Tx). RESULTS Bone alkaline phosphatase (BALP), osteocalcin (OC) and beta-crosslaps were significantly higher in Tx patients, and decreased significantly after one year. There was a negative correlation between BALP, OC and steroid administered (r = -0.35; r = -0.36 respectively). PWV increased in the Tx group (1.15 SD). In patients with a follow up of <24 months, PWV was correlated with BALP and beta-crosslaps (r=0.53; r = 0.69 respectively) while in the ≥24 months group, PWV was correlated with cholesterol (r=0.38). CONCLUSIONS Increased bone turnover and arterial stiffness are present following kidney transplantation. While bone turnover decreases with time, arterial stiffness correlates initially with bone turnover, after which the influence of cholesterol becomes significant. Non-invasive estimation of bone metabolism and arterial stiffness may help to assess CKD-MBD following renal transplantation.

Abstract
Corticosteroids have been widely used in the treatment of idiopathic thrombocytopenic purpura (ITP). We evaluated the late side effects of high-dose methylprednisolone (HDMP) therapy on bone metabolism in children with ITP. Twenty-eight children with acute ITP treated with HDMP (30 mg/kg/d for 3 d then 20 mg/kg/d for 4 d) and 28 controls were enrolled in the study. Bone mineral density (BMD), urinary calcium creatinine ratio, urinary levels of deoxypyridinoline, serum levels of calcium, phosphate, parathyroid hormone, total alkaline phosphatase, and bone-specific alkaline phosphatase were measured in both groups. Magnetic resonance imaging of the femoral head was performed only in study group. The mean levels of serum phosphate, parathyroid hormone, urinary deoxypyridinoline, and calcium creatinine ratio were significantly increased in the study group. There was no significant difference between the 2 groups in terms of serum calcium, total alkaline phosphatase, bone-specific alkaline phosphatase, and BMD values. There was a statistically significant negative correlation between cumulative steroid dose and BMD values in study group (r = -0.379). Osteonecrosis was observed in 3 of 25 patients by magnetic resonance imaging. In conclusion, HDMP therapy, especially in high cumulative doses, increases the bone resorption and may cause osteonecrosis in children with ITP.

Efficacy of intravenous alendronate for the treatment of glucocorticoid-induced osteoporosis in children with autoimmune diseases. Clin Rheumatol 2008; 27:909-12. [PMID: 18330609 DOI: 10.1007/s10067-008-0864-6] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2007] [Revised: 02/06/2008] [Accepted: 02/12/2008] [Indexed: 10/22/2022]
Abstract
Our objective was to investigate the efficacy of intravenous alendronate for the treatment of glucocorticoid-induced osteoporosis (GIOP) in children with autoimmune diseases. Five children with autoimmune disease and GIOP were treated with 5 mg intravenous alendronate once every 3 months. After 1 and 2 years, we evaluated the changes in the Z score of the femoral neck bone mineral density (BMD), serum bone alkaline phosphatase, and urinary deoxypyridinoline. Six patients with GIOP, whose BMD could be observed over a 1-year period without alendronate treatment, were defined as controls. After 1 and 2 years of treatment, intravenous treatment significantly inhibited bone loss. The efficacy of alendronate demonstrated a significant correlation with a high level of bone turnover markers before alendronate treatment. Intravenous alendronate is considered to be a good choice for the treatment of GIOP because of its excellent efficacy. In addition, our study suggests that the efficacy of alendronate depends on the bone turnover of patients before treatment. Intervention with bisphosphonates during periods of high bone turnover may be recommended.

Abstract
Renal transplantation in children has traditionally required immunosuppression with multiple medications including glucocorticoids. Data collected over almost 30 yr suggest that although glucocorticoids are efficacious as part of a regimen to minimize the incidence of acute rejection episodes, their use is associated with increased risk for post-transplant hypertension, hyperlipidemia, and reduced growth rates. We desired to reduce these complications and thus used an immunosuppressive protocol including daclizumab, tacrolimus, and mycophenolate mofetil and study the efficacy of this protocol in a population with a high percentage of African-American recipients. No patient received glucocorticoids at any time post-transplant. Our results show that at 1 yr post-transplant, glomerular filtration rate, serum glucose, calcium and phosphorous metabolism, serum magnesium, and serum lipids were similar in patients receiving steroid-free and those receiving steroid-based immunosuppression. The incidence of acute rejection was similar in the two groups. Hematocrit and white blood count levels were lower 1 month after transplant in the steroid-free patients but these levels increased within several months. Systolic blood pressure was similar in the two groups, although this was achieved, in part, in the patients who received steroids by the administration of medications to lower blood pressure. Finally, tacrolimus levels were similar in the two groups, but patients receiving steroids required higher doses of tacrolimus at several time points studied during the first post-transplant year. Taken together, our data suggests that at one-year follow-up, steroid-free immunosuppression is safe, and efficacious in pediatric renal transplant recipients.

Abstract
Glass-ceramic apatite-wollastonite (A-W)/high-density polyethylene composite (AWPEX) materials have been designed to match the mechanical strength of human cortical bone and to provide favourable bioactivity, with potential use in many orthopaedic applications. To better understand AWPEX properties, the effects of surface finish and ceramic filler size and content on osteoblast-like cell attachment, proliferation, and differentiation were examined. Glass-ceramic content was tested at 30 and 50 vol% and median particle size at 4.5 and 7.7 microm. Samples were prepared as 1 x 10 x 10 mm(3) tiles with polished or rough surfaces, sterilized by gamma irradiation (2.5 Mrad), and characterized by scanning electron microscopy (SEM) and surface profilometry. Saos-2 human osteoblast-like cells were cultured on each surface at an initial concentration of 4500 cells/cm(2) for 1, 3, or 7 days. At each time point, adenosine triphosphate and alkaline phosphatase levels were measured to assess cell number and osteoblast differentiation. SEM imaging of cells on the composite surfaces showed preferential cell attachment to filler particles within the polymer matrix. Significant biochemical assay differences were found at 7 days, confirmed by ANOVA post-hoc testing using Bonferroni's correction. Overall, increased exposure of the glass-ceramic A-W phase in AWPEX through surface polishing, higher volume fraction and/or larger particle size was found to lead to an improved cell response.
