Predicting lupus membranous nephritis using reduced picolinic acid to tryptophan ratio as a urinary biomarker
Summary: The current gold standard for classifying lupus nephritis (LN) progression is a renal biopsy, which is an invasive procedure. Undergoing a series of biopsies for monitoring disease progression and treatments is unlikely suitable for patients with LN. Thus, there is an urgent need for non-in...
