AIM: To investigate the linkage of matrix metalloproteinase (MMP) gene polymorphisms with the pathogenesis of knee osteoarthritis (OA). METHODS: This meta-analysis study systematically retrieved relevant studies from PubMed, Embase, the Cochrane Central, Wanfang Data, CNKI, and SinoMed up to November 2020. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the association between MMP gene polymorphisms and OA. RESULTS: A total of nine case-control studies comprising 1719 knee OA patients and 1904 controls were included in this meta-analysis...

AIM: To clarify the prognosis and prognostic factors for lung cancer in patients with rheumatoid arthritis (RA). METHODS: In this retrospective longitudinal study, we investigated the medical records of patients with RA among 1422 patients diagnosed with lung cancer and registered in a hospital-based cancer registry between January 2013 and May 2022. The Kaplan-Meier method and Cox proportional hazards model were used to analyze survival and identify predictive factors...

OBJECTIVE: To recruit immune-mediated necrotizing myopathy (IMNM) patients with extramuscular manifestations who were refractory to initial therapy with either monotherapy with prednisolone or dual therapy with prednisolone and immunosuppressants. These patients subsequently received a combination of prednisolone, tacrolimus, and intravenous immunoglobulin (IVIG), and the efficacy of this treatment regimen was assessed in patients with IMNM. METHOD: ①Clinical data and treatment measures are as follows: This study enrolled IMNM patients who were treated at the Neurology Department of the First Medical Center of PLA General Hospital from April 2020 to May 2023...

BACKGROUND: Epidemiological and observational studies have indicated an association between Sjögren's syndrome (SS) and Parkinson's disease (PD). However, consistent conclusions have not been reached due to various limitations. In order to determine whether SS and PD are causally related, we conducted a Mendelian randomization study (MR) with two samples. METHODS: Data for SS derived from the FinnGen consortium's R9 release (2495 cases and 365 533 controls)...

OBJECTIVE: To investigate the potential associations between functional capacity, muscle strength, body composition, and disease-related measures and quality of life in patients with myositis. METHODS: Baseline measures of functional capacity (functional index 3 (FI3), 2-minute walk test (2MWT), timed up and go (TUG) and 30-s sit-to-stand (30-STS)), muscle strength (incl. leg and handgrip strength), maximal leg extensor power, body composition (appendicular lean mass, fat percentage/mass) and disease-related measures (disease activity & damage core sets) were examined for their associations with quality of life (physical- and mental component summary scores, Short Form 36 questionnaire (SF-36)) by means of Spearman's correlation analysis...

OBJECTIVE: Glucocorticoids are effective in treating rheumatoid arthritis (RA) when used appropriately considering the balance of the risks and benefits, especially at low doses. We aimed to evaluate the response of biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in patients having already been treated with glucocorticoids. METHODS: We reviewed RA patients treated with b/tsDMARDs in a prospective multicenter ultrasound cohort study...

Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes inflammation and pain, which can lead to the loss of normal joint function. Although the exact cause of the disease is not yet fully understood, both environmental factors and genetics may play a role in its development. Moreover, research suggests microbiota contributes to the onset and progression of RA. People with RA show higher quantities of bacteria such as Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Prevotella copri, Proteus mirabilis, and Lactobacillus salivarius compared to healthy individuals...

PASS syndrome is a rare autoinflammatory disease characterized by acne vulgaris, hidradenitis suppurativa, pyoderma gangrenosum, and ankylosing spondylitis. Unlike other autoinflammatory disorders such as PAPA and PASH syndrome, there is no documented gene mutation link. Although there are no established treatment guidelines due to the rarity of these diseases, systemic corticosteroids, biologics, and immunosuppressive drugs are used currently. In our report, we presented a case of PASS syndrome who was unresponsive to adalimumab and in whom we observed improvement in both skin and joint manifestations with intravenous immunoglobulin (IVIG) and anti-IL-1 treatment...

BACKGROUNDS: Acute anterior uveitis (AAU) is the most common extra-musculoskeletal manifestation in axial spondyloarthritis (axSpA). OBJECTIVES: The aim of the study is to evaluate the factors associated with AAU attacks in patients with axSpA during a 36-month follow-up period. METHODS: In total, 469 patients with axSpA were included in this observational study. Demographic data, clinical characteristics, disease activity measurements, and treatment patterns were compared between patients with and without a history of AAU...

BACKGROUND: Sjögren's Syndrome (SS), mainly affecting women in their midlife, is characterized by persistent inflammation in glands producing tears and saliva, often leading to significant complications. This study investigates the differences in autonomic system functioning between individuals with SS and healthy controls. METHODS: From April 2019 to December 2022, 329 diagnosed primary SS (pSS) patients and 30 healthy controls were enrolled at Taipei Veterans General Hospital, Taipei, Taiwan...
