Sjogren Disease and Nephrolithiasis: A Case Series and Review of the Literature
Abstract
Background: Primary Sjogren Disease (pSD) is a chronic autoimmune disease characterized by a classic triad of keratoconjunctivitis sicca, xerostomia, and polyarthritis. The primary pathological feature of pSD is lymphoplasmacytic infiltration in glandular epithelial tissue, often affecting the salivary and lacrimal glands, leading to classic sicca symptoms (ocular and oral dryness). Sjogren Disease (SD) can be categorized as "primary" when occurring independently or "secondary" when accompanying another autoimmune connective tissue disorder such as rheumatoid arthritis, systemic lupus erythematosus, or systemic sclerosis. Additionally, systemic disease is common in pSD and can manifest with kidney dysfunction resulting in nephrolithiasis and distal renal tubular acidosis (dRTA). Methods: This report details a case series drawing patients from the literature as well as patients from our institution which serves to demonstrate key points in clinical hallmarks. We utilize a literature search with key words Sjogren Disease, nephrolithiasis, renal tubular acidosis, and nephrocalcinosis in addition to pSD patients with concomitant nephrolithiasis at our institution to characterize clinical and serologic findings as well as treatment modalities. Results: We find well demonstrated clinical hallmarks such as female predominance and presence of dRTA amongst the cohort of pSD patients. We also find that further research on pSD serologies could prove beneficial in risk stratifying those…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
