Patients' conceptions of their own influence on good treatment response to biological therapy in chronic inflammatory arthritis

Role of Platelets in Rheumatic Chronic Autoimmune Inflammatory Diseases

Platelets are essential in maintaining blood homeostasis and regulating several inflammatory processes. They constantly interact with immune cells, have immunoregulatory functions, and can affect, through immunologically active substances, endothelium, leukocytes, and other immune response components. In reverse, inflammatory and immune processes can activate platelets, which might be significant in autoimmune disease progression and arising complications. Thus, considering this interplay, targeting platelet activity may represent a new approach to treatment of autoimmune diseases. This review aims to highlight the role of platelets in the pathogenic mechanisms of the most frequent chronic autoimmune inflammatory diseases to identify gaps in current knowledge and to provide potential new targets for medical interventions.

Patients' Perceptions of Person-Centered Care in Early Rheumatoid Arthritis: A Qualitative Study

Objective

Most research on patient experiences of rheumatoid arthritis (RA) care is performed with patients who have established RA and less often with patients with early RA. Experiences of and expectations about health care may change over time, which is why the aim was to explore patients’ perceptions of person‐centered care (PCC) early in the RA disease course.

Methods

Thirty‐one patients with early RA were interviewed in this qualitative study. An abductive qualitative content analysis was conducted based on the framework of McCormack and McCance (1,2). The four constructs, prerequisites, care environment, person‐centered processes, and person‐centered outcomes, constituted the four categories in the deductive part of the study. An inductive analysis generated 11 subcategories exploring the content of PCC.

Results

For patients with early RA, PCC was described in terms of 1) prerequisites including being treated with respect, meeting dedicated health care professionals, and meeting professional competence; 2) care environment including having access to a multidisciplinary team, having access to health care, and encountering a supportive organization; 3) person‐centered processes including being listened to, being supported, and being involved in decision‐making; and 4) person‐centered outcomes including being satisfied with received health care and achieving optimal health.

Conclusion

Genuine PCC is important for patients early in the RA disease course, supporting the implementation of a person‐centered approach during all stages in the health care system. This study contributes to information about how to further develop person‐centeredness in rheumatology care.

Platelet indices in patients with chronic inflammatory arthritis: a systematic review and meta-analysis

Correlation between platelet indices and chronic inflammatory arthritis (CIA) remains a moot point today. This meta-analysis aimed to evaluate whether platelet (PLT) count, mean platelet volume (MPV) and platelet distribution width (PDW) associated with rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA). A systematic literature search was performed in PubMed, EMBASE, and Web of Science up to August 2019. Pooled standardized mean differences (SMD) and 95% confidence interval (CI) were calculated using a random-effect model. As a result, 34 studies were included, encompassing 17 on RA, 12 on AS, 3 on PsA and 2 on both RA and AS. In these studies, PLT count was significantly higher in RA (SMD = 0.55, 95% CI = 0.36-0.73, P < .001), AS (SMD = 0.53, 95% CI = 0.36-0.70, P < .001) and PsA patients (SMD = 1.29, 95% CI = 0.82-1.77, P < .001) than that in healthy subjects, while MPV and PDW presented nonsignificant differences in these intergroup comparisons (P > .05), and similar results were observed in subgroup analyses. The meta-regression analysis demonstrated that there were strong positive correlations between erythrocyte sedimentation rate and PLT count, and weak correlation trend between the disease activity score and PLT count in both RA and AS subjects without statistically significant difference. The sensitivity analysis indicated that these results were not unduly influenced by any single study. In conclusion, this meta-analysis demonstrated that PLT count was elevated in CIA patients and could be suitable for evaluating the disease activity, whereas MPV and PDW were independent of CIA.
