Information, social support and coping in patients with pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension-A nationwide population-based study

Objective: Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) decrease life expectancy for affected patients. The aim was to describe the perceptions of received information regarding diagnosis, treatment and management, as well as social support and coping perceived by patients with PAH or CTEPH. Methods: A descriptive, national cohort survey that included patients from all PAH-centres in Sweden. A quantitative methodology was employed where all patients received three questionnaires, QLQ-INFO25, Mastery Scale and Social Network & Support Scale. Results: The response rate was 74% (n. =325), mean age 66. ±. 14. years, 71% were female and 69% were diagnosed with PAH and 31% with CTEPH. Sixty percent of respondents were satisfied with the received information and felt it was helpful. Best experiences were of information in the areas of medical tests (70%) and the disease (61%). Forty-five percent wanted more information. Men described their social network as more accessible than women (p. =0.004). Those living alone had a lower coping ability. Conclusion: Despite a high level of satisfaction with the received information, almost half of the patients wanted more information. Practice implications: Regular repeating or giving new information should be an ongoing process in the care of patients at the PAH-centres

Perceptions of received information, social support, and coping in patients with pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension.

Patients with a life-limiting diagnosis of pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) need disease-specific information, ability to cope, and functioning social networks. This cohort study investigated the experiences of PAH and CTEPH patients who received information about their diagnosis, treatment, and management, in addition to coping and social support. Sixty-eight adult patients (mean ± SD, age 67 ± 14; 66% women) were included. A total of 54% of the patients wanted more information. Patients received information mostly in areas concerning medical test procedures, the diagnosis, disease severity, possible disease causes, and how to manage their disease. Coping ability was significantly better in patients who were satisfied with the received information (P = 0.0045). The information given to PAH or CTEPH patients and their communication with healthcare professionals can be greatly improved. Gaps in information and misunderstandings can be avoided by working in cooperation with the patients, their relatives, and within the PAH team

Serum COMP-C3b complexes in rheumatic diseases and relation to anti-TNF-alpha treatment

Introduction: Cartilage oligomeric matrix protein (COMP) is found at elevated concentrations in sera of patients with joint diseases such as rheumatoid arthritis (RA) and osteoarthritis (OA). We recently showed that COMP activates complement via the alternative pathway and that COMP-C3b complexes are present in sera of RA patients, but not in healthy controls. We now set out to elaborate on the information provided by this marker in a variety of diseases and larger patient cohorts. Methods: COMP-C3b levels in sera were measured by using an enzyme-linked immunosorbent assay (ELISA) capturing COMP and detecting C3b. Serum COMP was measured by using ELISA. Results: COMP-C3b levels were significantly elevated in patients with RA as well as in systemic lupus erythematosus (SLE), compared with healthy controls. SLE patients with arthritis had significantly higher COMP-C3b levels than did those without. COMP-C3b was furthermore elevated in patients with ankylosing spondylitis (AS), psoriatic arthritis (PsA), reactive arthritis, systemic sclerosis, and OA. COMP-C3b did not correlate with COMP in any of the patient groups. COMP-C3b correlated with disease activity in RA, but not in other diseases. COMP-C3b levels in RA patients decreased on treatment with tumor necrosis factor (TNF)-alpha inhibitors, whereas the levels increased in patients with AS or PsA. The changes of COMP-C3b did not parallel the changes of C-reactive protein (CRP). Conclusions: COMP-C3b levels are elevated in several rheumatologic diseases and correlate with inflammatory measures in RA. COMP-C3b levels in RA decrease during TNF-alpha inhibition differently from those of CRP, suggesting that formation of COMP-C3b relates to disease features not reflected by general inflammation measures

Identifying unmet needs in SSc-ILD by semi-qualitative in-depth interviews

Objectives Interstitial lung disease is frequent in SSc (SSc-ILD) and associates with significantly reduced quality of life. Here we aimed to analyse patient pathways, and experiences of patients and healthcare providers (HCPs) in order to identify unmet needs in the management of SSc-ILD patients. Methods Semi-structured qualitative interviews conducted in eight European countries looked at HCP (n = 95) and patient perspectives (n = 47) using two sets of 70 research questions. Pre-diagnostic, diagnostic and post-diagnostic phases of the patient pathway were systematically explored. Results (i) In the pre-diagnostic phase several gaps were identified by HCPs and patients in all participating countries: limited disease knowledge among primary care physicians and specialists, lack of accurate patient information, and delayed and/or inappropriate referral. (ii) The diagnostic phase is in most countries coordinated by rheumatologists, who are also the main point of care. Depending on the local health system, organization of multidisciplinary collaboration varies. HCPs issued lack of national guidelines, while patients stated difficulties obtaining disease-related information. (iii) In the post-diagnostic phase, HCPs and patients indicated lack of curative treatment, specialized nurses, and paramedical and psychological support. Patients and caregivers additionally expressed the need for clear information on SSc-ILD. Conclusion Lack of disease specific knowledge, gaps in national healthcare systems and insufficient information and support for patients and caregivers were identified as unmet needs to ensure timely diagnosis, provide better patient management and to improve quality of life in SSc-ILD patients.Peer reviewe

The Pronounced Th17 Profile in Systemic Sclerosis (SSc) Together with Intracellular Expression of TGFβ and IFNγ Distinguishes SSc Phenotypes

Contains fulltext : 81194.pdf (publisher's version ) (Open Access)BACKGROUND: Systemic sclerosis (SSc) is an autoimmune disease where controversy on Th1/Th2 balance dominates. We investigated whether the recently discovered Th17 pattern was present in SSc. METHODOLOGY AND PRINCIPAL FINDINGS: Patients were subdivided as having limited cutaneous SSc (lcSSc, n = 12) or diffuse cutaneous SSc (dcSSc, n = 24). A further arbitrary subdivision was made between early dcSSc (n = 11) and late dcSSc (n = 13) based upon the duration of disease. As a comparator group 14 healthy controls were studied. CD3+ cells were isolated using FACS and subsequently studied for the expression of CD4, CD8, CD25, CD45Ro, CD45Ra, IL-23, GITR, CD69 and intracellular expression of IL-17, TGFbeta and IFNgamma using flow cytometry. Levels of IL-17, IL-6, IL-1alpha and IL-23 were measured using Bioplex assays. SSc patients had more and more activated CD4+ cells. In addition, CD4, CD45Ro and CD45Ra cells from all SSc patients highly expressed the IL23R, which was associated with a higher IL-17 expression as well. In contrast, IFNgamma and TGFbeta were selectively up regulated in SSc subsets. In line with these observation, circulating levels of IL-17 inducing cytokines IL-6, IL-23 and IL-1alpha were increased in all or subsets of SSc patients. CONCLUSION AND SIGNIFICANCE: The combination of IL-17, IFNgamma and TGFbeta levels in CD45Ro and CD45Ra cells from SSc patients is useful to distinguish between lSSc, ldSSc or edSSc. Blocking Th17 inducing cytokines such as IL-6 and IL-23 may provide a useful tool to intervene in the progression of SSc

Intra-and inter-observer reliability of nailfold videocapillaroscopy - A possible outcome measure for systemic sclerosis-related microangiopathy

OBJECTIVES: Our aim was to assess the reliability of nailfold capillary assessment in terms of image evaluability, image severity grade ('normal', 'early', 'active', 'late'), capillary density, capillary (apex) width, and presence of giant capillaries, and also to gain further insight into differences in these parameters between patients with systemic sclerosis (SSc), patients with primary Raynaud's phenomenon (PRP) and healthy control subjects.METHODS: Videocapillaroscopy images (magnification 300×) were acquired from all 10 digits from 173 participants: 101 patients with SSc, 22 with PRP and 50 healthy controls. Ten capillaroscopy experts from 7 European centres evaluated the images. Custom image mark-up software allowed extraction of the following outcome measures: overall grade ('normal', 'early', 'active', 'late', 'non-specific', or 'ungradeable'), capillary density (vessels/mm), mean vessel apical width, and presence of giant capillaries.RESULTS: Observers analysed a median of 129 images each. Evaluability (i.e. the availability of measures) varied across outcome measures (e.g. 73.0% for density and 46.2% for overall grade in patients with SSc). Intra-observer reliability for evaluability was consistently higher than inter- (e.g. for density, intra-class correlation coefficient [ICC] was 0.71 within and 0.14 between observers). Conditional on evaluability, both intra- and inter-observer reliability were high for grade (ICC 0.93 and 0.78 respectively), density (0.91 and 0.64) and width (0.91 and 0.85).CONCLUSIONS: Evaluability is one of the major challenges in assessing nailfold capillaries. However, when images are evaluable, the high intra- and inter-reliabilities suggest that overall image grade, capillary density and apex width have potential as outcome measures in longitudinal studies
