Pediatric discoid lupus erythematosus (DLE) is a rare inflammatory skin disorder. This article aims to review all the available clinical and therapeutic data on reported cases of pediatric DLE. A systematic review of the literature was conducted using Pubmed and Embase with no limitation on publication date, sex, or nationality. Thirty-two articles were included with 201 cases, a mean age of 8.9 years (2 months-16 years) and an F:M ratio of 1.8. Lesions were located on the head and neck in 58.5% and were disseminated in 36.5% of the cases. Associated symptoms were pruritus (10.1%) and alopecia (8.7%). 12% progressed to systemic lupus erythematosus (SLE) and 14.5% had concurrent SLE. The only statistically significant predictor for progression to SLE was the onset of symptoms before or at the age of 10 years (p = 0.004). Treatments consisted mainly of sunscreens (26.3%), topical corticosteroids (24.3%), and oral antimalarials (25.3%). Retrospective nature of the included studies, small sample size, short duration of follow-up and limited data on the patients' demographics. Pediatric DLE affects mostly the head and neck, with a female predominance, a possible association with inflammatory and autoimmune diseases, and overall good treatment response and prognosis.

Distinct genetic risk loci between biopsy-proven renal and non-renal lupus: a 10-year longitudinal cohort.

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.

Background: Positive anti-ribonucleoprotein antibodies may characterize a subgroup of patients affected by lupus nephritis with mild kidney damage, but little is known about their clinical features and long-term prognosis.

Methods: Patients were retrospectively selected from the lupus nephritis database ( http://ln.medidata.

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.
