Dysregulation of complement factor H in juvenile-onset systemic lupus erythematosus patients.

Objectives: This study aims to evaluate the expression pattern of factor H in peripheral blood and the frequency of factor H autoantibodies in plasma of juvenile-onset systemic lupus erythematosus (jSLE) patients compared to healthy controls.

Patients And Methods: Between March 2019 and October 2019, a total of 30 healthy individuals (3 males, 27 females; mean age: 26±7.4 years; range, 18 to 40 years) and 65 jSLE patients (age of onset ≤16 years) (2 males, 63 females; mean age: 23.

Association of microRNA-125a with the clinical features, disease activity and inflammatory cytokines of juvenile-onset lupus patients.

Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with marked variation in its clinical presentation. Juvenile-onset SLE (jSLE) exhibits an aggressive clinical phenotype and severe complications. Dysregulated expression of microRNAs (miRs) in immune cells from patients with SLE has been found.

Immunological Evaluation in Patients with Familial Mediterranean fever.

Objective: This study aimed to investigate T & B lymphocyte subsets and Natural Killer (NK) cells patterns in children with FMF versus normal control subjects, to estimate the immunoglobulins IgG, IgM, and IgA levels, and to scrutinize the possible use of Neutrophil / Lymphocyte ratio (NLR) as a marker for subclinical inflammation in FMF patients.

Patients And Methods: A group of 42 patients with FMF attending the Genetics Clinic at National Research Centre were included in this study. They were 13 males and 19 females; their age ranged from 2 to 17 years old.
