Results of a global, patient-based survey assessing the impact of psoriatic arthritis discussed in the context of the Psoriatic Arthritis Impact of Disease (PsAID) questionnaire.

BACKGROUND: Psoriatic arthritis (PsA) is a chronic immune-mediated inflammatory musculoskeletal disease, manifesting as peripheral arthritis, enthesitis, dactylitis, spondylitis, and skin and nail psoriasis. A core set of domains for measuring the impact of PsA has been developed, including pain, patient global assessment, physical function, health-related quality of life (HRQoL), and fatigue. To understand the impact of PsA on health domains from a patient's perspective, a global survey was developed and results reported in the context of the 12-item Psoriatic Arthritis Impact of Disease (PsAID-12) questionnaire. METHODS: An online patient-based global survey was conducted by The Harris Poll in Australia, Brazil, Canada, France, Spain, Taiwan, the UK, and the US between November 2, 2017 and March 12, 2018. Eligible patients were ≥ 18 years old with a diagnosis of PsA for > 1 year, had visited a rheumatologist/dermatologist in the past 12 months and reported using ≥ 1 synthetic/biologic disease-modifying antirheumatic drug for PsA. Patients reported on PsA severity and symptoms, and the impact of PsA on HRQoL. After survey completion, responses were aligned with PsAID health domains. Descriptive statistics and chi-square tests were conducted. RESULTS: This analysis included 1286 patients from eight countries. Most patients (97%) reported musculoskeletal symptoms relating to PsA in the past year. Common moderate/major impacts of PsA were on physical activity (78%), ability to perform certain activities (76%), work productivity (62%), and career path (57%). Skin/nail symptoms occurred in 80% of patients. Overall, 69% of patients reported that PsA had a moderate/major impact on emotional/mental wellbeing, 56% on romantic relationships/intimacy, and 44% on relationships with family and friends. Social impacts included emotional distress (58%), social shame or disapproval (32%), and ceased participation in social activities (45%). Over half of all patients experienced unusual fatigue over the past 12 months (52%). The health domains that patients reported as being impacted by PsA aligned with life impact domains of the patient-derived PsAID health domains. CONCLUSION: These results highlight the impact of PsA on multiple health domains from a patient perspective that should be considered during shared decision-making processes between healthcare providers and patients.

A retrospective study of pulmonary infarction in patients with systemic lupus erythematosus from southern Taiwan.

Since large-scale reports of pulmonary infarction in systemic lupus erythematosus (SLE) are limited, a retrospective study was performed for this manifestation in 773 hospitalized patients in southern Taiwan from 1999 to 2009. Pulmonary infarction was defined as the presence of pulmonary embolism, persistent pulmonary infiltrates, and characteristic clinical symptoms. Demographic, clinical, laboratory, and radiological images data were analyzed. There were 12 patients with pulmonary embolism and 9 of them had antiphospholipid syndrome (APS). Six patients (19 to 53 years, average 38.2 ± 12.6) with 9 episodes of lung infarction were identified. All cases were APS and four episodes had coincidental venous thromboembolism. There were four episodes of bilateral infarction and seven episodes of larger central pulmonary artery embolism. Heparin therapy was routinely prescribed and thrombolytic agents were added in two episodes. Successful recovery was noted in all patients. In conclusion, there was a 0.8% incidence of pulmonary infarction in patients with SLE, all with the risk factor of APS. Differentiation between pulmonary infarction and pneumonia in lupus patients should be made; they have similar chest radiography with lung consolidation but require a different clinical approach in management. Although this report is a retrospective study with relatively small numbers of lupus patients with lung infarcts, our observation might provide beneficial information on the clinical features and radiological presentations during the disease evolution of pulmonary infarction in SLE with APS.

A retrospective study of catastrophic invasive fungal infections in patients with systemic lupus erythematosus from southern Taiwan.

As very few large scale publications of invasive fungal infection (IFI) have been reported in lupus patients from individual medical centers, a retrospective study was performed from 1988 to 2009 in southern Taiwan. Demographic characteristics, clinical and laboratory data, and mycological examinations were analyzed. Twenty cases with IFI were identified in 2397 patients (0.83% incidence). There were 19 females and one male with an average age of 31.8 +/- 12.6. Involved sites included eight disseminated cases, six central nervous system, four lungs, one abdomen and one soft tissue. IFI contributed to a high mortality with 10 deaths (50%), and there were no survivors for the disseminated cases and Candida-infected patients. High activity (Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) > 8) was noted in 50% of IFI episodes. The survival from IFI diagnosis to death was only 7.7 +/- 4.2 days, all in a rapid course. No statistical difference was found between survivors and non-survivors when comparing their SLEDAI. Eighty-five percent of IFI episodes under high dosages of corticosteroids therapy and 95% of patients had lupus nephritis. There was an increased risk of IFI in the lupus patients receiving high daily dosage of prednisolone therapy. Critical information from analyses of the present large series could be applied into clinical practices to reduce the morbidity and mortality in such patients.

Rare coexistence of gouty and septic arthritis: a report of 14 cases.

OBJECTIVES: To analyse the characteristic features of patients with coexistence of gouty arthritis and pyarthrosis at our university hospital in southern Taiwan, an area with high prevalence of hyperuricemia and gout. METHODS: A retrospective chart review was performed for patients who had concomitant gouty and septic arthritis from July 1998 to June 2008. Clinical and laboratory data of these patients were analysed. Furthermore, a comparison was made with published cases in English literature. RESULTS: Fourteen cases with coexistence of gouty arthritis and pyarthrosis have been identified during the past 10 years. There were 13 male and 1 female, all of Han Chinese in ethnicity, with ages ranging from 45 to 85 and an average of 63.7 years. At disease presentation, there were 11 oligoarticular cases (78.6%), 2 monoarticular cases (14.3%) and 1 polyarticular case (7.1%). Ankle and knee joints were most commonly involved. Bacteriological analyses demonstrated gram-positive cocci in 12 cases, of these 10 were oxacillin-sensitive Staphylococcus aureus (71.4%). Multiple tophi deposition was noted in 13 patients (92.9%) and among them 11 patients (84.6%) had associated chronic kidney disease. CONCLUSION: Different clinical presentations and bacteriological characteristics have been identified in the present series. While the mechanisms responsible for such a coexistence remain to be elucidated, these cases underline the importance of thorough evaluation of the aspirated synovial fluid. Our report adds a novel insight into the understanding of the clinical and microbiological manifestations of such a rare concurrence of gouty and septic arthritis.

Decreased CD4+CD25+bright T cells in peripheral blood of patients with primary Sjogren's syndrome.

CD4+CD25+bright T cells played a crucial role in the suppression of immune response. Recently, decreased levels of CD4+CD25+bright T cells in the peripheral blood of patients with systemic lupus erythematosus were reported, suggesting the potential role of CD4+CD25+bright T cells in human autoimmune diseases. Primary Sjögren's syndrome (pSS) is another common human systemic autoimmune disease. The present study aimed to investigate the levels of CD4+CD25+bright T cells in pSS and to correlate their levels with some biomarkers of inflammation and immune activation. Thirty-three patients with pSS and 35 age- and sex-matched normal individuals were enrolled in the study. The flowcytometric method was applied in the measurement of CD4+CD25+bright T cells. The results showed that patients with pSS had statistically lower levels of CD4+CD25+bright T cells than normal controls, expressed either as absolute cell numbers (mean+/-SD: 47.07+/-25.53 cells/mm3 versus 79.55+/-34.56 cells/mm3, P<0.001) or as percentages of peripheral blood mononuclear cells (mean+/-SD: 2.79+/-1.06% versus 3.84+/-1.42%, P<0.001) or as percentages of CD4+ T cells (mean+/-SD: 7.85+/-2.62% versus 11.68+/-3.78%, P<0.005). Moreover, there were statistically significant inverse correlations between the levels of CD4+CD25+bright T cells and some parameters of inflammation or immune activation including erythrocyte sedimentation rate, C-reactive protein, IgG and rheumatoid factors. The result suggested that CD4+CD25+bright T cells were likely to play anti-inflammatory and immunosuppressive roles in the pathogenesis of pSS. However, the exact functions of decreased circulating CD4+CD25+bright T cells in pSS need further elucidated.
