Long-Term Outcome of Interdisciplinary Management of Patients with Duchenne Muscular Dystrophy Receiving Daily Glucocorticoid Treatment.

OBJECTIVE: To evaluate clinical outcomes and steroid side effects in a cohort of patients with Duchenne muscular dystrophy (DMD) treated with long-term daily glucocorticoid therapy. Although daily glucocorticoid therapy has been shown to extend ambulatory function in DMD, less frequent dosing is often used because of side effect concerns. STUDY DESIGN: Retrospective study of 97 patients with DMD aged 10 to <16 years treated with daily glucocorticoid (89% on deflazacort) for a mean of 8.5 years. Outcome measures were motor, pulmonary, and cardiac function, and scoliosis. Side effects were growth failure and weight gain, facial fullness, blood pressure, bone health, cataracts, gastrointestinal symptoms, behavior, hypertrichosis, and need for medication interventions. RESULTS: For 13- to 16-year-old patients, 40% could rise from the floor and 50% could perform the 30-foot run test. Forced vital capacity for the entire cohort was well preserved. Thirteen percent of younger (10- to <13-year-old) and 21% of older patients had findings of left ventricle systolic dysfunction. Six percent (all aged 16 years) developed scoliosis (Cobb angle >20 degrees). Eighty-six percent had normal weight velocities; 30% had no increased facial fullness; 72% had short stature; and 19% had asymptomatic cataracts. Asymptomatic spine compression deformities were noted in 76% and long bone fractures in 30%. One patient stopped glucocorticoid because of behavioral concerns. CONCLUSIONS: With evidence for improved outcomes and manageable side effects, we recommend use of daily glucocorticoid therapy for patients with DMD with anticipatory management of side effects and a coordinated interdisciplinary care approach.

A study of the efficacy and safety of ciclesonide hydrofluoroalkane nasal aerosol in patients with seasonal allergic rhinitis from mountain cedar pollen.

A nasal aerosol formulation of ciclesonide with a hydrofluoroalkane propellant (CIC-HFA) is currently in development for treatment of allergic rhinitis (AR). This study evaluated the efficacy and safety of once-daily administration of CIC-HFA 74 or 148 micrograms compared with placebo in patients with seasonal AR (SAR) from mountain cedar pollen. Patients ≥12 years of age with a ≥2-year history of SAR from mountain cedar pollen were randomized in a placebo-controlled, double-blind, parallel group, multicenter study to CIC-HFA 74 micrograms, CIC-HFA 148 micrograms, or placebo once daily in the morning for 2 weeks. Change from baseline in reflective total nasal symptom score (rTNSS), instantaneous TNSS (iTNSS), and reflective total ocular symptom score (rTOSS) in patients with baseline rTOSS ≥5.00 were evaluated. Adverse events (AEs) were monitored throughout the study. A statistically significant improvement in rTNSS (least squares [LS] mean change from baseline 1.04 and 1.02 respectively; p < 0.0001 versus placebo for both) and iTNSS (LS mean change from baseline 0.90 and 0.83 respectively; p < 0.001 vs placebo for both) was observed after treatment with CIC-HFA 74- or 148-microgram doses. Only the CIC-HFA 74-micrograms treatment group showed a statistically significant improvement in rTOSS (LS mean change from baseline 0.52; p = 0.0124) compared with placebo. The overall incidence of AEs was low and comparable between the treatment groups. In this study, statistically significant improvements in nasal symptoms of SAR were observed after treatment with CIC-HFA 74-microgram or CIC-HFA 148-microgram doses. Both active treatments were well tolerated. Clinical trial registry URL and registration number: www.clinicaltrials.gov/ct2/show/NCT01010971.

Systemic side effects of inhaled corticosteroids in patients with asthma.

Asthma is a complex disease of the respiratory tract associated with chronic inflammation in which an intricate network of cells and cellular factors plays a major role. Asthma is one of the most common chronic diseases, with an estimated 300 million cases worldwide, imposing a considerable burden on society in morbidity, quality of life, and healthcare costs. Inhaled corticosteroids (ICSs) form the gold standard, first-line therapy in the effective management of persistent asthma and reduce morbidity and mortality from asthma. However, long-term use of high-dose ICS therapy has potential to cause systemic side effects-impaired growth in children, decreased bone mineral density, skin thinning and bruising, and cataracts. Hypothalamic-pituitary-adrenal-axis suppression, measured by serum or urine cortisol decrease, correlates with the occurrence of systemic side effects of high-dose ICSs. Therefore, cortisol may be a relevant surrogate marker to identify the potential for adverse effects from ICS therapy. Ciclesonide is a new generation ICS with demonstrable safety and efficacy in the treatment of asthma. The unique pharmacologic characteristics of ciclesonide, such as reduced local adverse effects, lack of cortisol suppression, and the option for once-daily dosing, may improve compliance with therapy and allow long-term use of ICSs without fear of systemic adverse effects.

Deflazacort in Duchenne muscular dystrophy: a comparison of two different protocols.

We compare the long-term benefits and side effects of deflazacort using two treatment protocols from Naples (N) and Toronto (T). Boys with Duchenne muscular dystrophy between the ages of 8 and 15 years and who had four or more years of deflazacort treatment were reviewed. Diagnostic criteria included males with proximal muscle weakness evident before 5 years, increased serum creatine kinase and genetic testing and/or a muscle biopsy consistent with Duchenne muscular dystrophy. Thirty-seven boys were treated with protocol-N using deflazacort at a dose of 0.6 mg/kg per day for the first 20 days of the month and no deflazacort for the remainder of the month. Boys with osteoporosis received daily vitamin D and calcium. Deflazacort treatment started between 4 and 8 years of age. Thirty-two were treated with protocol-T using deflazacort at a dose of 0.9 mg/kg per day, plus daily vitamin D and calcium. Treatment started between 6 and 8 years of age. All boys were monitored every 4-6 months. The results were compared with age-matched controls in the two groups (19 for protocol-N and 30 for protocol-T). For the boys treated with protocol-N, 97% were ambulatory at 9 years (control, 22%), 35% at 12 years (control, 0%), 25% at 15 years (control, 0%). For the 32 boys treated with protocol-T, 100% were ambulatory at 9 years (control, 48%), 83% at 12 years (control, 0%) and 77% at 15 years (control, 0%). No aids or leg braces were used for ambulation. In boys 13 years and older, a scoliosis of >20 degrees developed in 30% of the boys on protocol-N, 16% on protocol-T and 90% of controls. For protocol-N, no cataracts were observed while in protocol-T, 30% of boys had asymptomatic cataracts that required no treatment. Fractures occurred in 19% (control 16%) of boys on protocol-N and 16% (control, 20%) of boys on protocol-T. This report illustrates: (a) the importance of collaborative studies in developing treatment protocols in Duchenne muscular dystrophy and (b) the long-term beneficial effects of deflazacort treatment in both protocols. However, the protocol-T seems to be more effective and frequently is associated with asymptomatic cataracts.

Deflazacort versus prednisone in patients with giant cell arteritis: effects on bone mass loss.

OBJECTIVE: To compare bone mass loss due to deflazacort versus prednisone in longterm treatment of patients with giant cell arteritis (GCA) in a randomized double blind comparative trial. METHODS: Seventy-four patients were included in a prospective multicenter study. Half received deflazacort (DFZ) and the other half prednisone (PR) for a minimum of 12 months. Calcium and vitamin D supplements were also provided to all subjects. Our intent was (1) to evaluate bone mineral density, using dual energy x-ray absorptiometry, at baseline and comparatively at 3, 6, and 12 mo; vertebral fractures by Meunier score and size variations after 12 mo treatments were also analyzed; (2) to assess calcium/phosphate metabolism modifications in both groups at baseline and after 12 mo. RESULTS: No significant difference was observed between the 2 groups in terms of treatment efficacy. Patients taking PR were slightly older on average versus the DFZ group (74 vs 70 yrs). Bone mass loss between entry and month 12 was not statistically different in the PR group (-0.026 +/- 0.007 g/cm2) compared to the DFZ group (-0.03 +/- 0.005 g/cm2). No significant difference was found in Meunier score variations (0.77 and 1.18 in the PR and DFZ groups, respectively; p = 0.3), nor in vertebral size variations (-0.4 and -0.2 in the PR and DFZ groups, respectively; p = 0.4). There was no difference in calcium/phosphate metabolism evaluations at month 12. CONCLUSION: In older patients taking longterm glucocorticoids who are at risk of osteoporosis, deflazacort did not result in less bone loss than prednisone.

Effectiveness of nifedipine and deflazacort in the management of distal ureter stones.

OBJECTIVES: To evaluate the effectiveness of medical therapy during watchful waiting in patients with distal ureter stones. METHODS: Ninety-six patients with radiopaque stones located in the distal tract of the ureter and with stone sizes of 1 cm or smaller were involved in the study. The patients were randomly divided into two groups. Group A (n = 48) received oral treatment with 30 mg of deflazacort daily (maximum 10 days) plus 30 mg of slow-release nifedipine daily (maximum 4 weeks). Group B (n = 48) underwent a wait-and-watch approach. Both groups of patients were allowed to use diclofenac on demand. Statistical analyses were carried out using Student's t test, the chi-square test, and Fisher's exact test. RESULTS: The average stone size was 5.8 +/- 1.8 mm for group A and 5. 5 +/- 1.4 mm for group B. No statistically significant difference was found in stone size. Stone expulsion was observed in 38 (79%) of 48 patients in group A and in 17 (35%) of 48 patients in group B. The average expulsion time was 7 days (range 2 to 10) for group A and 20 days (range 10 to 28) for group B. A statistically significant difference was observed in both the expulsion rate and the expulsion time (P <0.05). The mean amount of sodium diclofenac used was 15 mg per patient for group A and 105 mg per patient for group B (P <0.05). CONCLUSIONS: The medical treatment proved to be effective and safe, as demonstrated by the increased stone expulsion rate, decreased expulsion time, and reduced need for analgesic therapy.

A comparison of aqueous suspensions of budesonide nasal spray (128 micrograms and 256 micrograms once daily) and fluticasone propionate nasal spray (200 micrograms once daily) in the treatment of adult patients with seasonal allergic rhinitis.

The efficacy of aqueous suspensions of budesonide nasal spray and fluticasone propionate nasal spray, in the treatment of seasonal allergic rhinitis, was compared in a large, placebo-controlled, two-center study. A 1-week baseline period was followed by a 4- to 6-week treatment period during which 635 adult patients, aged 18-72 years, were randomized to receive either placebo, budesonide 128 micrograms, or 256 micrograms once daily, or fluticasone propionate, 200 micrograms once daily. Nasal and eye symptoms, overall treatment efficacy and safety assessments were made during the study period. Combined, as well as individual, nasal symptoms were significantly improved in all three active treatment groups compared with placebo therapy. Treatment with 256 micrograms/day of budesonide was found to be significantly more effective in reducing the sneezing score compared with 200 micrograms/day of fluticasone propionate. Analysis of symptom scores on days when the pollen count was greater than 10 grains/m3 revealed 256 micrograms/day of budesonide therapy to be significantly more effective in reducing combined symptom scores as well as the individual scores for sneezing and runny nose, compared with 200 micrograms/day fluticasone propionate. The higher dose of budesonide (256 micrograms/day) was also more effective than the lower dose (128 micrograms/day) in reducing sneezing scores and statistical significance was almost reached for the reduction in combined symptom and runny nose scores. Substantial or total control of symptoms was achieved by 31.4%, 85.3%, 88.4%, and 81.9% of patients receiving placebo, 128 micrograms/day of budesonide, 256 micrograms/day of budesonide, and 200 micrograms/day of fluticasone propionate, respectively. The incidence of adverse events was low in all treatment groups. In conclusion, both budesonide and fluticasone propionate treatments were effective and well-tolerated in the treatment of seasonal allergic rhinitis. However, 256 micrograms/day of budesonide tended to be more effective than 200 micrograms/day of fluticasone propionate and 128 micrograms/day of budesonide, especially when patients were exposed to a higher pollen load.

Acute asthma during pregnancy.

BACKGROUND: Acute asthma during pregnancy is potentially dangerous to the fetus. The aim of this study was to investigate the effect of an acute attack of asthma during pregnancy on the course of pregnancy or delivery, or the health of the newborn infant, and to identify undertreatment as a possible cause of the exacerbations. METHODS: Five hundred and four pregnant asthmatic subjects were prospectively followed and treated. The data on 47 patients with an attack of asthma during pregnancy were compared with those of 457 asthmatics with no recorded acute exacerbation and with 237 healthy parturients. RESULTS: Of 504 asthmatics, 177 patients were not initially treated with inhaled corticosteroids. Of these, 17% had an acute attack compared with only 4% of the 257 patients who had been on inhaled anti-inflammatory treatment from the start of pregnancy. There were no differences between the groups as to length of gestation, length of the third stage of labour, or amount of haemorrhage after delivery. No differences were observed between pregnancies with and without an exacerbation with regard to relative birth weight, incidence of malformations, hypoglycaemia, or need for phototherapy for jaundice during the neonatal period. CONCLUSIONS: Patients with inadequate inhaled anti-inflammatory treatment during pregnancy run a higher risk of suffering an acute attack of asthma than those treated with an anti-inflammatory agent. However, if the acute attack of asthma is relatively mild and promptly treated, it does not have a serious effect on the pregnancy, delivery, or the health of the newborn infant.

Bone density in asthmatic patients taking inhaled corticosteroids: comparison of budesonide and beclomethasone dipropionate.

We assessed bone mineral density (BMD) in 20 asthmatics who had been taking inhaled budesonide (BUD) (median daily dose 800 micrograms) for over a year, 13 of whom had taken previous courses of systemic steroids. Their results were compared with those of 20 patients receiving inhaled high-dose beclomethasone dipropionate (BDP) (median daily dose 1,000 micrograms), all of whom had received previous courses of systemic corticosteroids, and with those of 17 mild asthmatics who had never taken either inhaled or systemic steroids. Mean (standard deviation) (SD)) BMD in the patients taking BUD was 139.5 (28.6) mg/ml. This was significantly lower (p < 0.05) than in the control patients who had never taken inhaled or systemic steroids (160.4 (27.4) mg/ml). Mean BMD in the patients taking BUD did not differ significantly from that observed in patients taking BDP (127.5 (22.6) mg/ml). Although the reduction in BMD in the asthma patients taking regular high-dose BUD could have been due to previous courses of corticosteroid, the magnitude of bone loss is similar to that seen in patients taking high-dose inhaled BDP and intermittent corticosteroids.

Budesonide. A review of its pharmacological properties and therapeutic efficacy in inflammatory bowel disease.

Budesonide is a glucocorticoid with high topical activity, but low systemic bio-availability which results in reduced systemic effects in comparison with other glucocorticoids. To date, it has been evaluated for use in patients with inflammatory bowel disease when administered either orally as a controlled ileal release formulation or rectally as an enema. In comparative trials, daily treatment with budesonide enema 2 mg/100ml for 4 weeks produced endoscopic remission or improvement in 46 to 84% of patients with active distal ulcerative colitis and/or proctitis and histological remission or improvement in 45 to 68%. In general, this regimen was effective as regimens of hydrocortisone, methylprednisolone, prednisolone or mesalazine (5-amino-salicylic acid, mesalamine) enemas, but caused less suppression of plasma cortisol levels than the other glucocorticoids. Oral treatment with controlled release budesonide 9 mg/day for 8 weeks produces clinical remission in 42 to 67% of patients with active Crohn's disease of the ileum, ileocaecal region and/or ascending colon and significantly reduces Crohn's disease activity index scores compared with baseline and placebo. Results of a quality-of-life questionnaire reflected these clinical improvements. Budesonide has similar efficacy to prednisolone. Response to budesonide is maintained after dosage tapering at 8 weeks. Compared with placebo, maintenance treatment with oral budesonide 3 or 6 mg/day increases the duration of remission in patients with Crohn's disease, but does not appear to affect the 1-year relapse rate. Thus, budesonide, administered rectally to patients with distal ulcerative colitis or proctitis or orally to patients with Crohn's disease of the ileum, ileocaecal region and/or ascending colon, is a favourable option for the treatment of acute exacerbations of inflammatory bowel disease. Because of the low incidence of adverse glucocorticoid-related effects associated with oral budesonide, it may also be a useful agent for longer term maintenance therapy if further clinical trials confirm its efficacy in this indication.

Acute effects of deflazacort and prednisone on rates of mineralization and bone formation.

The aims of this study were to determine (1) whether acute suppression of bone formation could be evaluated after the administration of corticosteroids in man by quantitative bone histomorphometry; and (2) whether there were significant differences between the effects of prednisone and its analog deflazacort. Thirteen patients who needed high-dose corticosteroid therapy were randomly allocated to two groups of treatment (prednisone or deflazacort). Quantitative bone histomorphometry, using the technique of triple labeling, and biochemical measurements of bone turnover were studied. There were no differences in biochemical indices of bone turnover between prednisone and deflazacort at the beginning and end of the 15 days of treatment course. During corticosteroid treatment, there were no significant changes in biochemical indices of bone turnover but a significant decline in total alkaline phosphatase (P < 0.01). Histomorphometric indices, as revealed by measurements of tetracycline interval and extent of labeling, showed no significant differences in either mineral apposition rate or bone formation rate in the two groups. We conclude that the acute glucocorticoid suppression of bone turnover by glucocorticoids is not detectable within the first 2 weeks of treatment by histomorphometric techniques. No differences in bone effects of prednisone and deflazacort were detected in this short-term study.

Comparison of budesonide and disodium cromoglycate for the treatment of seasonal allergic rhinitis in children.

BACKGROUND: Budesonide and disodium cromoglycate (DSCG) are commonly used agents for the treatment of seasonal allergic rhinitis. The comparative efficacy, however, of these agents in the pediatric population has not been reported. OBJECTIVE: The efficacy of nasally administered budesonide (400 micrograms/day, administered twice daily) was compared with that of DSCG (31.2 mg/day, administered six times per day) for the treatment of seasonal allergic rhinitis in children. METHODS: A single-blind parallel group study was carried out in 56 children (mean age 12 years) with seasonal allergic rhinitis. Treatment was for 3 weeks, during which patients assessed nasal symptoms, eye symptoms, and overall efficacy. RESULTS: Over the 3-week period, mean scores for the nasal symptoms of blocked nose, itchy nose, and sneezing were significantly lower with budesonide therapy than with DSCG. P values were .021, .0032, and .0016, respectively. Both treatment groups reported reduced scores for runny nose and eye symptoms; no statistically significant difference was observed between budesonide and DSCG. The global efficacy assessment scores show significantly more patients benefited from budesonide therapy than from DSCG treatment. CONCLUSIONS: The results suggest that nasally administered budesonide has greater efficacy than DSCG in the treatment of seasonal allergic rhinitis in children.

Effects of long-term use of high-dose inhaled steroids on bone density and calcium metabolism.

BACKGROUND: Inhaled steroids are the mainstay in the antiinflammatory treatment of asthma. In the last few years, these agents have been used in increasing doses. Because high doses of inhaled steroids can reduce serum osteocalcin levels, there are concerns regarding their long-term effects on bone metabolism. METHODS: We examined the effects of doses of 800 micrograms/day or greater of beclomethasone or budesonide for more than 18 months in 37 asthmatic subjects (group A), matched to a control group of 37 asthmatic subjects using little or no inhaled steroids (< 500 micrograms, group B). All had a clinical evaluation, measurements of expiratory flows, and determination of serum creatinine, calcium, phosphate, gamma-glutamyl transpeptidase, alkaline phosphatase, cortisol, and osteocalcin levels. A 2-hour urinary sample was obtained for creatinine, calcium, phosphate, hydroxyproline, and cortisol measurements. Bone density was assessed at the lumbar spine level and at the hip with a Hologic-QDR-2000 osteodensitometer (Hologic, Boston, Mass.). RESULTS: The mean (+/- SD) daily dose of inhaled steroids over the last 2 years was 1140 +/- 353 micrograms in group A (mean duration of use of > 800 micrograms/day, 34.2 +/- 13.0 months) and 89 +/- 98 micrograms for group B (mean duration of use of < 500 micrograms/day, 15.7 +/- 18.8 months). The number of oral steroid treatments (< 15 days) during the last 2 years was small in the two groups, 0.92 +/- 1.27 in group A and 0.05 +/- 0.23 in group B (p > 0.05). The only differences between our two groups in terms of serum or urinary parameters were for mean osteocalcin level, which was lower in group A (2.16 +/- 1.09 ng/ml) than in group B (2.70 +/- 0.98 ng/ml) (p = 0.029), and in mean urinary phosphorous level, which was higher in group A (1.44 +/- 0.76 mmol/2 hr) than in group B (1.26 +/- 0.89 mmol/2 hr (p = 0.034). Mean urinary hydroxyproline levels were 15.51 +/- 6.98 mumol/2 hr in group A and 13.53 +/- 7.13 mumol/2 hr in group B (p > 0.05). Mean mineral bone densities of the lumbar spine and hip were similar in the two groups with values of 0.923 +/- 0.136 gm/cm2 and 0.719 +/- 0.147 gm/cm2 in group A and 0.933 +/- 0.154 gm/cm2 and 0.694 +/- 0.095 gm/cm2 in group B (p > 0.05). The T and Z scores for lumbar spine were -1.32 +/- 1.22 and -0.85 +/- 1.02 in group A and -1.19 +/- 1.33 and -0.72 +/- 1.08 in group B (p > 0.05). There was no correlation between the duration or dose of steroid use and bone density or osteocalcin. Although the serum osteocalcin level was lower in the group of subjects using high-dose inhaled steroids, suggesting an osteoblastic depression, bone density was not significantly different compared with the control group. CONCLUSIONS: This study shows that although the serum osteocalcin level was lower and the urinary phosphorus level was higher in subjects using high-dose inhaled steroids for a mean of 34 months, compared with a control group, no significant difference in bone density or other markers of bone metabolism was found between the two groups.

Pharmacokinetics of budesonide enema in patients with distal ulcerative colitis or proctitis.

Pharmacokinetic data obtained after one dose of a 2-mg budesonide enema were compared with data obtained after the last dose of four weeks of daily treatment in 24 patients with active distal ulcerative colitis or proctitis. This open multicentre study involved 28 eligible patients. Sigmoidoscopy and biopsy scores improved significantly (P < 0.002) during the four-week treatment period. Maximal plasma concentration (Cmax) of budesonide was 2.1 nmol/L 1.3 h after the first dose and 2.5 nmol/L 1.2 h after the last dose; the difference was not significant. The area under the curve (AUC) of plasma concentration vs. time was after the first dose 9.7 nmol h/L and after the last dose 11.6 nmol h/L (P < 0.03). The small increase in AUC may be attributed to improved absorption. During the last dose interval, minimal plasma concentration was below the limit of quantitation in most subjects. The Cmax and AUC of budesonide increased slightly after four weeks of treatment, but budesonide did not accumulate. Mean morning plasma cortisol values did not change significantly during treatment (P = 0.083), although a small change in cortisol levels between the first visit (pre-treatment) and last visit was positively correlated to the Cmax of budesonide measured at the last visit (P = 0.012).

Protective effects of deflazacort on allergen-specific conjunctival challenge.

The protective effects of deflazacort, (a new heterocyclic glucocorticoid and derivative of prednisolone, with calcium and glucose-sparing effects) on the inflammatory reaction following an allergen-specific conjunctival provocation test (CPT) were assessed in a double-blind study, in 24 patients suffering from rhinoconjunctivitis due to Parietaria judaica. After an initial screening CPT, patients were randomized to four treatment groups, to receive deflazacort, 6, 30 or 60 mg, once daily or placebo, for 3 days, during the low-pollen season. Clinical evaluations (itching, hyperaemia, lacrimation and eyelid swelling), cytological assessment (number of inflammatory cells, i.e. neutrophils, eosinophils and lymphocytes, sampled by conjunctival scraping) and immunocytochemical evaluation of CD54 (intercellular adhesion molecular-1 [ICAM-1]) expression on epithelial cells were performed after CPT, at baseline, after 30 minutes (early-phase reaction [EPR]) and after 6 and 24 hours (late-phase reaction [LPR]), before and after treatment. Neither the nature or severity of clinical events nor the total number of inflammatory cells during the EPR changed during treatment with deflazacort. The severity of the clinical events during the LPR were significantly reduced by deflazacort, 30 and 60 mg/day P < 0.01) compared to the placebo-treated group. The total number of inflammatory cells during the LPR was also significantly reduced by deflazacort, 30 and 60 mg/day (P < 0.01) compared to the placebo-treated group. CD54 expression was significantly reduced by deflazacort, 30 and 60 mg/day both during the EPR (P < 0.01) and LPR (P < 0.01) compared to the placebo-treated group.(ABSTRACT TRUNCATED AT 250 WORDS)

Glucocorticoid-induced osteoporosis in the lumbar spine, forearm, and mandible of nephrotic patients: a double-blind study on the high-dose, long-term effects of prednisone versus deflazacort.

The long-term effects of high dose steroid treatment with either prednisone (PDN) or deflazacort (DFZ) were examined on various parts of the skeleton in 29 patients with nephrotic syndrome. All had normal skeleton at the start of the steroid treatment. At the beginning, PDN was given as 80 mg/day and tapered down to 20 mg/day for 1 year and DFZ was given in an equipotent dosage. Twenty-three patients completed 6 months of treatment, and 18 patients completed 12 months of treatment. Beside laboratory parameters to ensure the effect of treatment on the nephrotic syndrome, all had measurements of the bone mineral content (BMC) at 0, 6, and 12 months of treatment. BMC was measured by single photon absorptiometry of both forearms and by dual photon absorptiometry of the mandible, forearms, and lumbar spine. The effect of DFZ was compared to that of PDN due to a potential "calcium sparing" effect of DFZ. The therapeutical effects on the nephrotic syndrome were not different between the two drugs. Urinary 24-hour protein decreased from 9.9 to 1.1 g in the DFZ-treated patients and from 8.0 to 1.4 g in the PDN-treated patients. Plasma albumin concentration normalized in both groups. Both groups of steroid-treated patients had a significant reduction of the BMC levels in all parts of the skeleton. However, the bone decay rates per month were significantly different between different bone regions and between different drug regimes. In the forearm, the bone decay rate was 5.3%/year in the PDN group and 2.0%/year in the DFZ group (P less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Steroid-induced mandibular bone loss in relation to marginal periodontal changes.

Long-term high-dose glucocorticosteroid treatment may be suspected as causing profound marginal periodontal bone loss due to the immunosuppressive/antiinflammatory effects and due to the osteoporotic side-effects. This study comprised an analysis of the loss of the mandibular and forearm bone mineral content (BMC), measured in vivo by dual-photon scanner, in relation to the concomitant changes of the periodontal indices (visible plaque, gingival bleeding, loss of attachment) in 17 acute nephrotic dentate patients undergoing intensive steroid treatment for 12 months. The measurements were performed at start of treatment, when all patients were considered healthy as regards the skeleton, and at the 6-month and 12-month follow-up. The mean BMC loss at the standard sites of the mandible and the forearm bones was 5.6%/year at both sites. No significant changes could be demonstrated in the periodontal indices (P greater than 0.10), and no relation was found between the mandibular BMC loss and the periodontal condition (R = 0.06, P greater than 0.10). In conclusion, profound marginal periodontal bone loss does not seem to be a prominent side-effect of long-term glucocorticosteroid treatment, although the degree of induced osteopenia in the mandible corresponds to that in other cortical bones of the skeleton.

Budesonide once-daily in seasonal allergic rhinitis.

A randomized, parallel group, double-blind multi-centre study was carried out in 342 patients with symptomatic seasonal allergic rhinitis to assess the efficacy and tolerability of intranasal budesonide administered either as a single morning dose of 400 micrograms or as a 200 micrograms twice-daily dose, morning and evening, for 4 weeks. Both treatments improved the symptoms of seasonal allergic rhinitis; specific nasal symptom scores recorded daily by the patient being reduced. The proportions of patients symptom free after 4-weeks' treatment were 46% in the 400 micrograms once-daily group and 54% in the 200 micrograms twice-daily group, with total daily symptom scores recorded by diary cards reduced by 79% and 80%, respectively. The differences between the groups were not statistically significant. Sub-group analysis of patients allergic to grass pollen (n = 166) showed similar total symptom scores at each level of grass pollen exposure (no significant difference between treatment groups). Patients assessed both treatments to be effective (no significant difference between groups), with 65% of patients questioned stating a preference for a once-daily treatment given equal symptom control. Both treatments were equally well tolerated and few side-effects were reported.

Comparison of the efficacy and side effects of aqueous steroid nasal spray (budesonide) and allergen-injection therapy (Pollinex-R) in the treatment of seasonal allergic rhinoconjunctivitis.

The efficacy and side effects of two approaches to the treatment of ragweed pollen-induced rhinoconjunctivitis were compared in a double-blind, parallel-group trial. Sixty ragweed-sensitive adults were randomized either to a course of four Pollinex-R hyposensitization injections during the 6 weeks before the ragweed-pollen season, or to budesonide aqueous nasal steroid spray, 400 micrograms daily, throughout the season. A double-dummy technique was used to achieve blinding. During the ragweed-pollen season, troublesome nasal symptoms were treated with terfenadine, 60 mg, when treatment was needed, up to 240 mg daily, and eye symptoms were treated with naphazoline eye drops, when treatment was needed, up to four times daily. Every day, subjects recorded the severity of nasal and eye symptoms and medication use in a diary. Fourteen of the subjects receiving Pollinex-R were unable to complete the course of injections because of systemic or large local reactions. Eight subjects withdrew during the pollen season because of severe rhinitis; all subjects had received Pollinex-R. Subjects in the budesonide-treated group had minimal nasal symptoms and used very little terfenadine, compared with subjects in the Pollinex-R-treated group (p less than 0.0001). Eye symptoms and eye drop use were similar in the two treatment groups. No clinically important side effects were reported by the subjects receiving budesonide. The results of this study suggest that aqueous budesonide nasal spray is markedly more effective than Pollinex-R in controlling symptoms of seasonal rhinitis while the side effects and inconvenience of immunotherapy are avoided.
