Nintedanib for Systemic Sclerosis-Associated Interstitial Lung Disease

BACKGROUND: Interstitial lung disease (ILD) is a common manifestation of systemic sclerosis and a leading cause of systemic sclerosis-related death. Nintedanib, a tyrosine kinase inhibitor, has been shown to have antifibrotic and antiinflammatory effects in preclinical models of systemic sclerosis and ILD. METHODS: We conducted a randomized, double-blind, placebo-controlled trial to investigate the efficacy and safety of nintedanib in patients with ILD associated with systemic sclerosis. Patients who had systemic sclerosis with an onset of the first non-Raynaud's symptom within the past 7 years and a high-resolution computed tomographic scan that showed fibrosis affecting at least 10% of the lungs were randomly assigned, in a 1:1 ratio, to receive 150 mg of nintedanib, administered orally twice daily, or placebo. The primary end point was the annual rate of decline in forced vital capacity (FVC), assessed over a 52-week period. Key secondary end points were absolute changes from baseline in the modified Rodnan skin score and in the total score on the St. George's Respiratory Questionnaire (SGRQ) at week 52. RESULTS: A total of 576 patients received at least one dose of nintedanib or placebo; 51.9% had diffuse cutaneous systemic sclerosis, and 48.4% were receiving mycophenolate at baseline. In the primary end-point analysis, the adjusted annual rate of change in FVC was 1252.4 ml per year in the nintedanib group and 1293.3 ml per year in the placebo group (difference, 41.0 ml per year; 95% confidence interval [CI], 2.9 to 79.0; P=0.04). Sensitivity analyses based on multiple imputation for missing data yielded P values for the primary end point ranging from 0.06 to 0.10. The change from baseline in the modified Rodnan skin score and the total score on the SGRQ at week 52 did not differ significantly between the trial groups, with differences of 120.21 (95% CI, 120.94 to 0.53; P=0.58) and 1.69 (95% CI, 120.73 to 4.12 [not adjusted for multiple comparisons]), respectively. Diarrhea, the most common adverse event, was reported in 75.7% of the patients in the nintedanib group and in 31.6% of those in the placebo group. CONCLUSIONS: Among patients with ILD associated with systemic sclerosis, the annual rate of decline in FVC was lower with nintedanib than with placebo; no clinical benefit of nintedanib was observed for other manifestations of systemic sclerosis. The adverse-event profile of nintedanib observed in this trial was similar to that observed in patients with idiopathic pulmonary fibrosis; gastrointestinal adverse events, including diarrhea, were more common with nintedanib than with placebo

Leuchtmittel mit einem Schichtsystem zur Reflektierung abgegebener infraroter Strahlung

DE1004011976 A UPAB: 20051109 NOVELTY - The illuminant has an illuminating body that is surrounded by a bulb (11) e.g. quartz bulb and a hard glass bulb. A layer system is partially surrounding the illuminant and is transparent to visible light. The system that is arranged on an inner side of the bulb includes three layers (20, 30, 40). The layers (20, 40) are made up an insulator or a dielectric, and the layer (30) is made up of a transparent metal. USE - Used for reflecting an infrared radiation (claimed). ADVANTAGE - The illuminant is partially surrounded by the layer system that is transparent to visible light, thus increasing efficiency of the illuminant by more than 20 percent when compared to conventional illuminants. The illuminant remains consistent even for a temperature more than 600 degree centigrade, and hence increasing life span of a lamp e.g. bulb

Synergism of imatinib mesylate and everolimus in attenuation of bronchiolitis obliterans after rat LTX

Bronchiolitis obliterans (BO) is a progressive and fatal disease after lung transplantation (LTX). Dysregulated growth factor-induced proliferation of myofibroblasts seems to be responsible for the development of BO. The aim was to confirm the efficacy of both inhibitors of receptor tyrosine kinases (RTKI) and of mammalian target of rapamycin (mTORI) after rat LTX. We used a rat model of left lung allotransplantation (F344-to-WKY) to evaluate the effect of imatinib (RTKI; 20 mg/kg/day; postoperative day (POD) 0-100) alone or in combination with everolimus (mTORI; 2.5 mg/kg/day; POD 14-100). Non-treated animals were the reference. In non-treated rats, acute rejection (AR) peaked between POD 20 and 30 (19/19) and ended in chronic rejection (CR) on POD 60/100 (12/12). Imatinib alone did not prevent AR (6/6), but attenuated the degree of degenerated bronchioles on POD 30 (non-treated, 57%; imatinib, 4%), and increased the allografts free of CR on POD 60/100 (3/12). A combination of imatinib and everolimus significantly reduced AR, attenuated fibrotic degenerated bronchioles (5%) and vessels (non-treated, 24%; combination therapy, 11%) on POD 30, and reduced fibrotic degenerated vessels (non-treated, 97%; combination therapy, 43%) and bronchioles (non-treated, 88%; combination therapy, 34%) on POD 60/100. Fifty percent of the animals were completely free of BO and vasculopathy. In conclusion, co-application of RTKI and mTORI attenuated the development of BO and vasculopathy. Thus, imatinib might be an interesting therapeutic approach after LTX

Utilization and determinants of use of non-pharmacological interventions in COPD: Results of the COSYCONET cohort.

Background: Guidelines for chronic obstructive pulmonary disease (COPD) recommend supplementing pharmacotherapy with non-pharmacological interventions. Little is known about the use of such interventions by patients. We analyzed the utilization of a number of non-pharmacological interventions and identified potential determinants of use.Methods: Based on self-reports, use of interventions (smoking cessation, influenza vaccination, physiotherapy, sports program, patient education, pulmonary rehabilitation) and recommendation to use were assessed in 1410 patients with COPD. The utilization was analyzed according to sex and severity of disease. Potential determinants of utilization included demographic variables and disease characteristics and were analyzed using logistic regression models.Results: Influenza vaccination in the previous autumn/winter was reported by 73% of patients. About 19% were currently participating in a reimbursed sports program, 10% received physiotherapy, 38% were ever enrolled in an educational program, and 34% had ever participated in an outpatient or inpatient pulmonary rehabilitation program. Out of 553 current or former smokers, 24% had participated in a smoking cessation program. While reports of having received a recommendation to use mainly did not differ according to sex, women showed significantly (p < 0.05) higher utilization rates than men for all interventions except influenza vaccination. Smoking was a predictor for not having received a recommendation for utilization and also significantly associated with a reduced odds of utilization. We found a correlation between recommendation to use and utilization.Conclusions: Utilization of non-pharmacological interventions was lower in men and smokers. A recommendation or offer to use by the physician could help to increase uptake
