Conclusions Lupus nephritis can present as nephritic and/or nephrotic syndrome with various combinations of edema, constitutional symptoms, proteinuria, hematuria, impaired renal function, abnormal lipid profile and hypertension. It remains however unclear how these antibodies become localized in the glomerulus. Systemic lupus erythematosus (SLE, or lupus) is an autoimmune disease. COVID-19 is an emerging, rapidly evolving situation. Histone is a protein in chromatin that play role in gene regulation. Diagnosis is based on renal biopsy. Th17 cells play role in LN by causing inflammation in nephrons. Figure 1 Pathogenesis of lupus nephritis. Furthermore, NP-SLE can be present even when the overall disease activity is stable or improving after treat - ment for SLE-related symptoms, such as lupus nephritis, cytopenia or arthritis. We focus on rethinking how innovative therapies for lupus nephritis should be evaluated and evolving strategies to more efficiently mitigate irreversible nephron loss in patients with lupus nephritis.
