Subclinical Renal Dysfunction in Rheumatoid Arthritis

4. september 2026 opdateret af: Nermeen Ebrahim Barsoum, Assiut University

Assessment of Subclinical Renal Dysfunction in Rheumatoid Arthritis and Its Association With Disease Activity

This comparative cross-sectional study aims to determine the prevalence of subclinical renal dysfunction in patients with rheumatoid arthritis and to evaluate its association with disease activity and inflammatory markers compared with age- and sex-matched healthy controls at Assiut University Hospitals.

Detaljeret beskrivelse

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease that may be associated with early renal involvement even before overt chronic kidney disease develops. Subclinical renal dysfunction refers to early impairment of renal function that is not detected by conventional serum creatinine alone.

This hospital-based comparative cross-sectional study will include two groups: patients with rheumatoid arthritis diagnosed according to the 2010 ACR/EULAR classification criteria, and age- and sex-matched apparently healthy controls. All participants will undergo clinical assessment, disease activity evaluation using DAS28, laboratory investigations including estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR), and renal ultrasonography. The study will determine the prevalence of subclinical renal dysfunction and assess its association with disease activity, inflammatory markers, serological markers, disease duration, and treatment-related factors.

Foranstaltningsbeskrivelse
Tidsramme
Prevalence of subclinical renal dysfunction
Tidsramme: Baseline
Proportion of participants with subclinical renal dysfunction, defined as the presence of reduced estimated glomerular filtration rate (eGFR < 90 mL/min/1.73 m²) and/or elevated urine albumin-to-creatinine ratio (UACR ≥ 30 mg/g) in the absence of previously diagnosed chronic kidney disease.
