Abstract
OBJECTIVE Our aim is to study the association between bronchial asthma (BA) and periodontitis in Jordan. METHODS A case control study of 260 subjects; 130 with BA and 130 without BA (controls) were recruited at a university hospital in Jordan. BA cases were physician-diagnosed and on anti-asthma medications for 12 months. Periodontitis was defined as the presence of ≥ 4 teeth with ≥ 1 site with probing pocket depth (PPD) ≥ 4 mm and clinical attachment level (CAL) ≥ 3 mm. RESULTS Mean age of participants was 45.3 years (range, 18-65) and 58.1% were females. Patients with BA had lower education and tended to live in rural areas. Periodontitis was present in 52 (40.0%) patients with BA and 26 (20.0%) in the control group, p < 0.005. Binary logistic regression indicated that patients with BA were more likely to have periodontitis than controls [adjusted odd ratio (OR) = 2.91, 95% CI (1.39-6.11), p = 0.005]. Patients with BA had higher percentage of sites with: PPD ≥ 3 mm, CAL ≥ 3 mm, and CAL ≥ 4 mm than controls, p < 0.05. The risk of periodontitis [OR = 5.27, 95% CI (1.59-17.51)] and CAL ≥ 3 mm were higher in patients on oral corticosteroids compared to inhaled corticosteroids, p < 0.05. CONCLUSIONS Adult Jordanians with bronchial asthma are at higher risk of periodontitis, particularly those on oral corticosteroids. Large and longitudinal studies are needed to better understand this significant association.

Abstract
BACKGROUND Pediatric bone health is an important part of the safety assessment of inhaled corticosteroids and certain other drugs. Current regulatory guidance for assessment of bone health for intranasal and inhaled corticosteroid drugs is a single 1-year study of linear growth. OBJECTIVE The objective of this study was to assess whether a significant change in bone mineral density (BMD) could be observed during a 12-month period in pediatric patients being treated for asthma with an inhaled corticosteroid using a previously conducted study. METHODS The publicly available information from the Childhood Asthma Management Program (CAMP) study was used to assess whether a statistically significant difference in BMD could be detected over a 1-year period. Patients who were at Tanner stage ≥2 were excluded from analysis as is stated in the present FDA Guidance on growth studies with inhaled corticosteroids, and children with any use of oral corticosteroids were also excluded. A comparison in BMD change over time (bone mineral accretion [BMA]) between baseline and 12 months of follow-up was made for the placebo and inhaled budesonide groups using multiple regression analysis to account for age, race, and gender as covariates. RESULTS From the original 1041 patients in the CAMP study, 74 patients met the criteria for evaluation, with 42 patients receiving budesonide and 32 placebo patients. Children randomized to budesonide had a lower mean BMA than those receiving placebo (0.021 ± 0.023 [SD] g/cm2/y vs 0.036 ± 0.025 [SD] g/cm2/y). CONCLUSION In a select pediatric patient population, a significant change in BMA can be observed over 12 months on an inhaled corticosteroid. Based on this post hoc analysis, measurement of BMA as an assessment of pediatric bone health may be considered for certain drugs, especially when there is a potential signal of bone toxicity from animal or human data. The clinical relevance of this finding is presently unknown, and more data on the relationship between changes in BMA and clinical pediatric bone health outcomes are needed.

Abstract
PURPOSE The purpose of our research was to compare the body mass index (BMI) and selected anthropometric parameters in asthmatic and non-asthmatic pubescents. MATERIAL AND METHODS The study group consisted of 64 asthmatic boys and 45 girls; the control group consisted of 68 nonasthmatic boys and 48 non-asthmatic girls. All the children were 12-14 years old. We measured anthropometric parameters by a standardized method and the percentage of fat using the simple 2-site skinfold method. Additionally, we calculated the percentage of body composition (Matiegka) and the components of somatotype (Heath-Carter). Statistical significance was estimated at the level of p<0.05 by ANOVA test. RESULTS The asthmatic boys were significantly shorter than the non-asthmatic (p=0.015), however, we did not find any significant differences in weight and/or BMI in boys nor girls. The asthmatic boys had significantly higher fat mass % than the non-asthmatic ones (p<0.001). Moreover, they had significantly lower muscle mass % (p<0.001) as well as the bone mass % (p<0.001). The asthmatic girls had higher fat mass % than the non-asthmatic ones (p=0.028) and lower muscle mass % (p<0.001). The simple 2-site skinfold method also showed higher fat % in the asthmatic boys (p<0.001) but not in the girls. Examining the Heath-Carter somatotype components, the higher endomorphy was the only significant difference in asthmatic boys (p<0.001) and near significant in asthmatic girls (p=0.053). CONCLUSION Examination of the BMI alone is not sufficient in asthmatic children because of their high percentage of fat. That is why additionally testing fat % is recommended.

Abstract
Potent, topically active corticosteroids with minimum systemic activity have fewer adverse effects than do systemic corticosteroids, and can control both asthma and allergic rhinitis when given in recommended doses. However, study findings show that children with asthma receiving budesonide and beclometasone dipropionate have decreased linear growth, and that children who receive long-term inhaled corticosteroid therapy for asthma have height deficits 1-2 years after treatment initiation that persist into adulthood. The effects of inhaled corticosteroids on growth seem to be dependent on both dose and duration; the degree of systemic effects is dependent on pharmacokinetic properties (ie, absorption, distribution, and elimination), whereas the effective dose delivered is dependent on the delivery system and potency of the molecule. The effects of corticosteroids on bone mineral density in children seem to be more amenable to intervention; long-term therapy with inhaled corticosteroid therapy is safer than frequent bursts of oral corticosteroids on bone mineral accretion in this regard. Importantly, adequate nutrition (particularly sufficient intake of calcium and vitamin D) should prevent or blunt the effects of corticosteroids on bone mineral density. The potential adverse effects of inhaled corticosteroids need to be weighed against the large and well established benefit of these drugs to control persistent asthma. To minimise any adverse effects, treatment with inhaled corticosteroids should always aim to reach the lowest effective dose that gives the patient good asthma control.

Abstract
UNLABELLED Boys with Duchenne muscular dystrophy often have reduced bone mass and increased fracture risk. In this prospective study on 33 patients, calcifediol (25-OH vitamin D(3)) plus adjustment of dietary calcium to the recommended dose reduced bone resorption, corrected vitamin D deficiency, and increased bone mass in about two-thirds of cases. INTRODUCTION Low BMC and BMD and bone metabolism alterations are frequent in boys with Duchenne muscular dystrophy (DMD), especially now that long-term glucocorticosteroid (GC) treatment is the standard of care. This prospective study was designed to evaluate the effects of a first-line treatment (25-OH vitamin D(3) [calcifediol] plus adjustment of dietary calcium to the recommended daily dose) on bone. METHODS Thirty-three children with DMD on GC treatment were followed for 3 years: one of observation and two of treatment. MAIN OUTCOME spine and total body BMC and BMD increase; secondary outcome: changes in bone turnover markers (C-terminal [CTx] and N-terminal [NTx] telopeptides of procollagen type I; osteocalcin [OC]). RESULTS During the observation year, BMC and BMD decreased in all patients. At baseline and after 12 months, serum CTx and urinary NTx were higher than normal; OC and parathyroid hormone at the upper limit of normal; 25-OH vitamin D(3) significantly lower than normal. After 2 years of calcifediol and calcium-rich diet, BMC and BMD significantly increased in over 65% of patients, and bone metabolism parameters and turnover markers normalized in most patients (78.8%). During the observation year, there were four fractures in four patients, while during the 2 years of treatment there were two fractures in two patients. CONCLUSIONS Calcifediol plus adequate dietary calcium intake seems to be an effective first-line approach that controls bone turnover, corrects vitamin D deficiency, and increases BMC and BMD in most patients with DMD. Lack of response seems related to persistently high bone turnover.

Abstract
OBJECTIVE Systemic corticosteroids are known to induce osteoporosis and increase the risk for fractures in adults and children. Inhaled corticosteroids have been shown to increase the risk for osteoporosis and fractures in adults at risk; however, long-term prospective studies of children to assess risks of multiple short courses of oral corticosteroids and chronic inhaled corticosteroids have not been performed. Thus, we assessed the effects of multiple short courses of oral corticosteroids and long-term inhaled corticosteroids on bone mineral accretion over a period of years. METHODS This was a cohort follow-up study for a median of 7 years of children who had mild-to-moderate asthma and initially were randomly assigned into the Childhood Asthma Management Program trial. Serial dual-energy radiograph absorptiometry scans of the lumbar spine for bone mineral density were performed for all patients. Annual bone mineral accretion was calculated for 531 boys and 346 girls who had asthma and were aged 5 to 12 years at baseline (84% of the initial cohort). RESULTS Oral corticosteroid bursts produced a dosage-dependent reduction in bone mineral accretion (0.052, 0.049, and 0.046 g/cm(2) per year) and an increase in risk for osteopenia (10%, 14%, and 21%) for 0, 1 to 4, and >or=5 courses, respectively, in boys but not girls. Cumulative inhaled corticosteroid use was associated with a small decrease in bone mineral accretion in boys but not girls but no increased risk for osteopenia. CONCLUSIONS Multiple oral corticosteroid bursts over a period of years can produce a dosage-dependent reduction in bone mineral accretion and increased risk for osteopenia in children with asthma. Inhaled corticosteroid use has the potential for reducing bone mineral accretion in male children progressing through puberty, but this risk is likely to be outweighed by the ability to reduce the amount of oral corticosteroids used in these children.

Abstract
OBJECTIVE To explore the association between inhaled corticosteroids (ICS) therapy and bone metabolism. PATIENTS AND METHODS The sample was composed of 151 children, aged between 1 and 17 years. There were 71 asthmatics treated with ICS for at least 6 months (group 1), 44 asthmatics treated occasionally with ICS during exacerbations (group 2), and 36 healthy children (group 3). Bone mineral density (BMD) and markers of bone formation and resorption were measured. These measures, as well as other related factors, were compared among groups. Regression models for osteopenia and BMD were used with the group as the independent variable adjusted by factors with differences between groups. A two-tailed level of p < 0.05 was used in all tests. RESULTS No differences in BMD were found between groups 1 and 2 but significant differences were found between groups 1 and 3 (p = 0.003). No differences were found in markers of bone formation and resorption among the groups. No association was found between BMD and the type, daily dose or accumulated dose of ICS. Group 1 showed an osteopenia odds ratio relative to group 3 of 2.94 (95 % CI: 1.49-5.78) and an average reduction of BMD of 0.50 (95 % CI: 0.32-0.68) was found from group 3 to 2 and from group 2 to 1. In group 1, markers of bone resorption significantly increased in asthmatics with osteopenia compared with those without osteopenia. CONCLUSIONS ICS treatment in asthmatic children seems to affect BMD. Markers of bone formation and resorption are unaffected. Osteopenia in these children could also be related to other factors that increase bone resorption.

Abstract
Inhaled corticosteroids are established as the mainstay of maintenance therapy for chronic asthma. However, there remains some debate regarding the safety of long-term use of these agents, particularly in children. This concern mainly stems from the findings of short-term studies assessing the effects of inhaled corticosteroids on lower leg growth rate or the hypothalamic-pituitary-adrenal axis. However, the clinical relevance of these findings to long-term treatment is unknown and significant uncertainty exists regarding the predictive value of changes in cortisol levels and clinically relevant changes in growth or bone mineral density. To assess the safety of long-term use of inhaled corticosteroids in children with asthma, a systematic review of the literature was performed focusing on randomised, controlled studies of >or=12 months' duration, to obtain data with maximum relevance to clinical practice. Specific searches were conducted to identify studies examining each of the following three areas: growth, bone mineral density and cortisol levels. Fourteen studies met the inclusion criteria for statural growth, four for bone mineral density, and ten for cortisol levels. There was some evidence of a small decrease in statural growth during the initial period of inhaled corticosteroid therapy. This effect was more marked at daily doses of >200 microg and did not apply to all treatment regimens. Studies examining final attained adult height found no difference between patients treated with inhaled corticosteroids and those receiving nonsteroidal therapy. None of the studies investigating effects on bone mineral density found any adverse effects of inhaled corticosteroid therapy. Finally, recommended doses of inhaled corticosteroids generally had little or no effect on plasma- or urinary-cortisol levels versus nonsteroidal therapy. In conclusion, this literature review supports the theory that recommended doses of inhaled corticosteroids can be administered to children for the long-term management of asthma with minimal risk of clinically relevant adverse effects on growth, bone density or cortisol levels.

Abstract
Rate of fracture was examined according to age at first fracture in 313 New Zealand children (145 girls, 168 boys) under l3 years of age (95.4% of a consecutive series of children treated at one hospital for a recent confirmed fracture at any site). In their lifetimes they had experienced 468 separate fracture events, over half (54.7%) occurring in the 32.3% of children breaking bones on more than one occasion. Children experiencing a first fracture before 4 years of age had 36.7 (95%CI 30.7-44.1) fractures per l00 years of exposure: this was a significantly higher rate than that of children experiencing their first fracture later in life. Thus, using the <4.0 year age group as a reference, we found that rate ratios (adjusted for gender) for groups that had suffered the first fracture at later ages were: first fracture between 4.0 and 6.99 years, 0.77 (95%CI 0.58-1.03); first fracture between 7.0 and 9.99 years, 0.63 (95%CI 0.42-0.94); first fracture between 10.0 and 12.99 years, 0.48 (95% CI 0.32-0.72). Asthma was over-represented (31% seen, 25% expected), and a high proportion of the sample (32.9%) used corticosteroid medications; however, neither characteristic affected age at first fracture. In contrast, the large number (n= 42) of youngsters (13.4% of the sample) reporting adverse reactions to milk were younger at first fracture than children without reactions to milk (P<0.05). We conclude that children experiencing their first fracture at a young age have high rates of fracture and should be targeted for advice to improve their bone strength.

Abstract
R411 is a dual alpha4beta1-alpha4beta7 integrin antagonist under development for the treatment of chronic asthma. The objective of this study was to investigate the pharmacokinetics and safety of R411 and its active metabolite, RO0270608, in humans. A 3-part phase I trial was conducted in 132 healthy volunteers: (1) 12 subjects received 200 mg R411 as a single oral dose or 100 mg RO0270608 as an intravenous infusion in a 1-sequence crossover design; (2) 7 groups of 10 subjects received 1 of 7 single oral doses of R411 (10-1200 mg) in a parallel, placebo-controlled, ascending adaptive dose design; and (3) 5 groups of 10 subjects each received repeated oral qd doses of R411 (50-900 mg) for up to 3 weeks in a parallel, placebo-controlled, ascending adaptive dose design. The absolute bioavailability of RO0270608 (mean +/- standard deviation) after oral administration of R411 was 27% +/- 4%, and the terminal half-life was 7.33 +/- 2.29 hours. After IV infusion of RO0270608, total clearance (mean +/- standard deviation) was 19.4 +/- 7.1 L/h, and the volume of distribution was 93.1 +/- 36.1 L. After single ascending oral doses of R411, area under the concentration-time curve from 0 to infinity of active metabolite RO0270608 increased proportionally from 150 to 1200 mg (P > .05). Following repeated administration, the oral clearance was independent of time. No drug accumulation was observed, and no safety concerns were revealed up to a dose of 900 mg after up to 3 weeks of treatment.

Abstract
Bone mineral density (BMD) is frequently reduced in children and adolescents with Cushing's disease (CD), but there is little follow-up data after cure. BMD was determined by dual energy X-ray absorptiometry (DEXA) in two groups of patients with CD. Group 1 comprised 8 patients, 5 males and 3 females, aged 12.4 yr (8.2-16.8), assessed at diagnosis. Group 2 comprised 11 subjects, 6 males and 5 females, diagnosed at age 13.3 yr (6.4-17.4), cured by transsphenoidal surgery (TSS) (no.=7) or TSS + pituitary irradiation (no.=4). They had measurement of BMD, at mean age of 18.3 yr (11.1-28.5), i.e. 4.5 yr (0.8-11.4) after cure. Four patients, mean age 20.2 yr (17.6-22.4), had repeated DEXA'scans, 1-4 times, for up to 5.8 yr. After cure, GH deficiency was present in 9 patients and treated with hGH in 8. In Group 1, patients' L2-L4 volumetric (v)BMD Z-score was variable with a mean of -1.04 (-3.21-0.11). L2-L4 vBMD Z-score values correlated negatively with midnight cortisol (p < 0.05). In Group 2, mean L2-L4 vBMD was -0.38 (-1.0-0.13); and in 7/11, mean femoral neck (FN) areal (a)BMD Z-score was 0.14 (-1.62-2.46). FN aBMD Z-score was higher than L2-L4 aBMD Z-score (p < 0.05). In patients with repeated scans, mean change in L2-L4 vBMD Z-score was 0.20 (-0.15-0.45), and mean change in FN aBMD Z-score 0.03 (-0.53-0.38). These findings show variability of BMD at diagnosis and near normal BMD after cure of pediatric CD, suggesting that with appropriate replacement of pituitary hormone deficiency normal peak bone mass is achievable.
