OBJECTIVE: To identify risk factors for the development of non-thyroidal illness syndrome (NTIS) in patients with systemic lupus erythematosus (SLE). METHODS: A retrospective analysis of 517 SLE patients and 1034 age-and sex-matched healthy population was conducted to compare the prevalence of NTIS in these two groups, and to analyze the laboratory and clinical characteristics of SLE patients with NTIS. Finally Logistic regression analysis was used to determine the risk factors for NTIS in SLE patients...

OBJECTIVES: Systemic sclerosis (SSc) is a complex immune-mediated connective tissue disease, involving skin manifestations, vascular features, and organ-based complications that may affect functional capacity and physical activity. Functional capacity and physical activity are associated with arterial stiffness; however, this relationship has not been evaluated in patients with SSc. Therefore, the objective of this study was to investigate the association of functional capacity and physical activity with arterial stiffness in patients with SSc...

INTRODUCTION/OBJECTIVES: Controversy exists regarding the concordance of patient-reported outcome measures (PROMs) with other assessment parameters in systemic sclerosis-associated interstitial lung disease (SSc-ILD). This study aims to explore the association between the St. George's Respiratory Questionnaire (SGRQ) and various outcome measures in patients with SSc-ILD within a real-world cross-sectional setting. METHOD: Patients with SSc-ILD were consecutively recruited from our SSc cohort...

To identify the value of salivary gland ultrasound (SGUS) combined with magnetic resonance imaging (MRI) and magnetic resonance sialography (MRS) in predicting the results of labial salivary gland biopsy (LSGB) in patients with suspected primary Sjögren syndrome (pSS), and construct a nomogram model to predict LSGB results. A total of 181 patients who were admitted with suspected pSS from December 2018 to April 2023 were examined and divided into a training set (n = 120) and a validation set (n = 61)...

OBJECTIVE: Systemic lupus erythematosus (SLE) is associated with a significant risk of atherosclerotic cardiovascular disease, especially in the development of premature atherosclerosis. Specific prediction models for premature atherosclerosis in SLE patients are still limited. The objective of this study was to establish a predictive model for premature atherosclerosis in SLE. METHOD: The study collected clinical and laboratory data from 148 SLE patients under the age of 55, between January 2021 and June 2023...

OBJECTIVE: To evaluate the relationship of gardening/yardwork with symptomatic and structural progression in those with pre-existing radiographic knee osteoarthritis (OA) in the Osteoarthritis Initiative (OAI), an observational study designed to evaluate potential and known biomarkers and risk factors of knee OA. METHODS: We conducted a cohort study nested within the OAI, including participants ≥ 50 years old with radiographic OA in at least one knee at the time of OAI enrollment...

OBJECTIVE: This study aimed to evaluate the value of machine learning models (ML) based on MRI radiomics in diagnosing early parotid gland injury in primary Sjögren's syndrome (pSS). METHODS: A total of 164 patients (114 in the training cohort and 50 in the testing cohort) with pSS (n=82) or healthy controls (HC) (n=82) were enrolled. Itksnap software was used to perform two-dimensional segmentation of the bilateral parotid glands on T1-weighted (T1WI) and fat-suppressed T2-weighted imaging (fs-T2WI) images...

OBJECTIVE: In this prospective cohort study, we provide several prognostic models to predict functional status as measured by the modified Health Assessment Questionnaire (mHAQ). The early adoption of the treat-to-target strategy in this cohort offered a unique opportunity to identify predictive factors using longitudinal data across 20 years. METHODS: A cohort of 397 patients with early RA was used to develop statistical models to predict mHAQ score measured at baseline, 12 months, and 18 months post diagnosis, as well as serially measured mHAQ...

BACKGROUND: In Behçet's disease (BD), mild-to-severe valvular regurgitation (VR) poses a serious complication that contributes significantly to heart failure and eventually death. The accurate prediction of VR is crucial in the early stages of BD subjects for improved prognosis. Accordingly, this study aimed to develop a nomogram that can detect VR early in the course of BD. METHODS: One hundred seventy-two patients diagnosed with Behçet's disease (BD) were conducted to assess cardiac valve regurgitation as the primary outcome...

OBJECTIVES: To summarize and analyze the results of published randomized controlled trials of tofacitinib for the treatment of chronic plaque psoriasis and psoriatic arthritis(PsA) and discuss its efficacy and safety. PATIENTS AND METHODS: An exhaustive systematic search encompassing PubMed, Cochrane, Embase, and Web of Science databases was conducted up to July 2023. Studies eligible for inclusion were analyzed, organized using Review Manager version 5.4.1 (Cochrane Collaboration, Oxford, UK) and STATA 15...

This overview of reviews aimed to synthesize the effectiveness of non-pharmacological approaches to enhance self-efficacy in people with osteoarthritis. The CINAHL, Embase, PsycINFO, PubMed, SPORTDiscus, and the Cochrane Library databases were searched from inception to December 2023. We considered systematic reviews with meta-analysis of randomized clinical trials evaluating any non-pharmacological intervention. We used AMSTAR 2 to assess the methodological quality of reviews. The overlap between reviews was calculated...

OBJECTIVES: To analyze clinical characteristics, risk factors, pathogen distribution, and prognostic markers in primary Sjögren's syndrome (pSS) patients with severe pneumonia (SP) compared to those without severe pneumonia (NSP). METHODS: This case-control study included 24 hospitalized pSS patients with SP and 96 NSP at the first affiliated hospital of Soochow university from June 2014 to May 2023. Data encompassing demographics, comorbidities, treatments, and laboratory results were retrospectively collected...

INTRODUCTION: Mixed connective tissue disease (MCTD) is a rare systemic disease characterized by overlapping features of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), dermato-/polymyositis (DM/PM), and rheumatoid arthritis (RA). Naifold capillaroscopy (NFC) is a non-invasive test for evaluating the capillaries of the nail shaft used in the diagnosis of rheumatic diseases. OBJECTIVES: To determine whether there are characteristic abnormalities in NFC in MCTD patients, and whether the type of NFC lesions correlates with organ involvement in these patients...

OBJECTIVES: Systemic lupus erythematosus (SLE) and the Epstein-Barr virus (EBV) are very closely related. This study estimated the impact of EBV infection status on clinical manifestations and disease remission in patients with SLE. METHOD: A retrospective study was performed using electronic health records of patients with SLE. The SLE disease activity index (SLEDAI-2 K) was used to assess disease activity. VCAIgM or EAIgM positive or EBVDNA copies ≥ 50 IU/mL were defined as lytic infection group, EBNA-IgG or VCAIgG-positive and who were negative for both VCAIgM and EAIgM with EBVDNA copies < 50 IU/mL were defined as the latent infection group...

Rheumatoid arthritis (RA) and osteoporosis are two chronic disorders that are often seen together. RA is an autoimmune disorder that causes pain and inflammation in the joints, while osteoporosis is a disorder in which the bones become weak and fragile. Risk factors for bone loss in RA include disease activity, longer disease duration, erosive disease, autoantibody positivity, and joint damage leading to impaired physical activity. Recent research has shown that there is a complex interplay between immune cells, cytokines, and bone remodeling processes in both RA and osteoporosis...
