ABSTRACT
AIM: To assess clinical and demographic characteristics of severe asthma (SA) patients and their management in Russian Federation. MATERIALS AND METHODS: This publication provides data for Russian part of population of the international observational study. In Phase I, retrospective analysis of medical records of patients with SA was performed with assessment of clinical and demographic data, medical history, comorbidities, treatment approaches and healthcare utilization. Phase II was a cross-sectional collection of patient-reported outcomes: level of asthma control assessed by ACT (Asthma Control Test) and health-related quality of life (HRQoL) measured using the EQ-5D-5L questionnaire. Phase I patients were enrolled into Phase II if they signed a written consent form. RESULTS: A total of 315 patients were included in Phase I of the study, 106 (33.6%) of them entered Phase II. Majority of study participants were either obese (n=103; 39.8%) or overweight (n=94; 36.3%). The most common comorbidities were cardiovascular diseases (n=217; 71.4%), followed by chronic respiratory diseases (n=198; 68.8%). There were 268 (85.1%) patients who had at least one exacerbation during last 12 months. Data for blood eosinophil count were available in 176 patients; 81.3% of them (n=143) had only one test in the last 12 months. The mean (SD) last available blood eosinophil count was 161.2 (181.2) cells/mm3. Serum Immunoglobulin E (IgE) value was known for 88 patients, and the mean (SD) last measured IgE value was 254.3 (249.7) ng/mL. Only 4.7% of Phase II participants had ACT scores indicative of controlled asthma (>20). As much as 74.5% had scores ≤15 suggesting uncontrolled disease. Most patients also had impaired HRQoL. CONCLUSION: Most SA patients had poor disease control with frequent exacerbations and high number of comorbidities. Blood eosinophils and IgE level measurements were not evaluated routinely which might be a barrier for appropriate phenotyping and treatment selection.

In fall 1998 CMS implemented the National Medicare Education Program (NMEP) to educate beneficiaries about their Medicare program benefits; health plan choices; supplemental health insurance; beneficiary rights, responsibilities, and protections; and health behaviors. CMS has been monitoring the implementation of the NMEP in six case study sites as well as monitoring each of the information channels for communicating with beneficiaries. This article describes select findings from the case studies, and highlights from assessment activities related to the Medicare & You handbook, the toll-free 1-800-MEDICARE Helpline, Internet, and Regional Education About Choices in Health (REACH).

cDNA encoding the core protein of rat syndecan was cloned from a neonatal rat aortic cDNA library by polymerase chain reaction amplification. Expression of syndecan mRNA in rat aortic vascular smooth muscle (VSM) cells was demonstrated by reverse transcriptase-linked polymerase chain reaction amplification of syndecan sequences using total RNA from rat aortic VSM cells as templates. Polyclonal antibodies against rat syndecan core protein were produced by immunizing rabbits with a recombinant fusion protein containing a fragment of the extracellular domain. The anti-syndecan antibodies immunoprecipitated a large 35SO4-labeled molecule synthesized by cultured rat aortic VSM cells. The immunoprecipitated molecule was identified as a hybrid proteoglycan, based on results of alkaline, nitrous acid, and chondroitinase ABC digestions. On immunoblots the antibodies recognized a proteoglycan of greater than 200 kDa, with a core protein size after deglycosylation of approximately 50 kDa. The anti-syndecan antibodies stained cultured rat aortic VSM cells as well as tissue sections of neonatal and adult rat aortas in the medial, smooth muscle layer. On Northern blots of RNA isolated from cultured VSM cells, a syndecan cDNA probe hybridized to a major RNA species of 2.6 kilobases. Quantitative Northern blot analysis of total RNA isolated from VSM cells harvested at different cell densities revealed a decrease in syndecan mRNA levels with increased cell density. These results demonstrate the regulated synthesis of syndecan by rat VSM cells.
