The aim of this study was to determine the role of vitamin A in modulating T helper 17 (Th17) and regulatory T cell (Treg) balance in systemic lupus erythematosus (SLE) patients. Sixty-two female SLE patients and sixty-two female controls were measured for vitamin A levels from serum by enzyme-linked immunosorbent assay (ELISA) and percentages of Th17 and Treg from peripheral blood mononuclear cells (PBMC) by flow cytometry. We also performed an in vitro study to evaluate the effects of retinoic acid treatment (0, 0.1, 0.2, and 0.3 μg/ml) in modulating Th17/Treg balance in CD4(+) T cell culture from hypovitaminosis A SLE patients. Th17 and Treg percentages from cell cultures were measured by flow cytometry. Vitamin A levels in the SLE patients were lower compared to those in the healthy control (46.9 ± 43.4 vs. 75.6 ± 73.1 ng/ml, p = 0.015). Vitamin A levels also had a negative correlation to Th17 percentages in the SLE patients (p = 0.000, R = -0.642). Th17 percentages in the hypovitaminosis A SLE patients were higher compared to those SLE patients with normal vitamin A levels (10.9 ± 5.3 vs. 2.9 ± 2.2 %, p = 0.000). Treatment of 0.3 μg/ml of retinoic acid could increase Treg differentiation (33.9 ± 1.6 vs. 21.8 ± 1.1 %, p = 0.000) and decrease Th17 differentiation (27.2 ± 2.5 vs. 37.4 ± 1.3 %, p = 0.000). In conclusion, vitamin A has important roles in modulating Th17/Treg balance in the SLE patients shown by the significant decrease of vitamin A levels in the SLE patients which negatively correlate with Th17 population, and treatment of retinoic acid could decrease Th17 and increase Treg percentages in CD4(+) T cells cultures.

Objective: Systemic lupus erythematosus (SLE) is a heterogeneous disease which manifests as different subphenotypes. Distinct subphenotypes, such as lupus nephritis (LN), have been associated with increased genetic risk, but prior studies have been limited by cross-sectional and imprecisely subphenotyped cohorts. This study investigated the genetic basis for LN using a longitudinal cohort of distinctly subphenotyped patients.

This study aims to explore the long-term physical, neurological, social and emotional development outcomes of the offspring born to patients with systemic lupus erythematosus (SLE), and to provide insights that can assist pediatricians in enhancing the long-term prognosis of these children. We conducted a cross-sectional study on the offspring of SLE patients who had undergone pregnancy and were admitted to our obstetrics department between January 1, 2016 and September 30, 2021. The control group consisted of offspring born to mothers without connective tissue disease, and was matched 1:1 based on age (birth date ± 1 month) with the offspring of SLE patients.

Unlabelled: Mitral annular calcification (MAC) is a chronic degenerative process involving the fibrous support structure of the mitral valve. The prevalence of this condition significantly increases with age, and is higher in patients with cardiovascular risk factors or end-stage renal disease. However, patients with systemic lupus erythematosus (SLE) may develop atherosclerosis and MAC at a relatively young age.

Background Systemic Lupus Erythematosus (SLE) is a multifaceted autoimmune disorder with diverse clinical presentations, among which hematological abnormalities often serve as early and critical indicators of disease. These manifestations, including anemia, leukopenia, lymphopenia, and thrombocytopenia, correlate with disease activity and provide essential diagnostic insights, particularly in resource-limited settings where access to advanced diagnostic tools may be constrained. This study emphasizes the significance of hematological findings that frequently appear at the initial presentation of SLE.

Introduction: Systemic lupus erythematosus (SLE) complicated by thrombotic microangiopathy (TMA) and non-cirrhotic portal hypertension (NCPH) is rare. We present a case of a female patient with SLE who developed TMA and NCPH and responded positively to rituximab and plasma exchange treatment.
Case Description: A 53-year-old woman was admitted with 6 h of confusion.
