Abstract
Systemic lupus erythematosus (SLE) is an autoimmune multisystem disease that is characterized by various antibodies to nuclear and cytoplasmic antigens and diagnosed by either fulfilling the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria, American College of Rheumatology (ACR) criteria or by Renal Biopsy. Renal involvement is common in SLE and is primarily related to anti-double-stranded DNA antibodies. However, small group of SLE nephritis patients have shown negative anti-dsDNA and ANA. We present a case of 25-year-old female who presented with proteinuria and negative serum antibodies except anti-Ro/SSA. Renal biopsy was performed and was consistent with class IV lupus nephritis (LN). In this report, we highlight the possible role of anti-Ro antibodies in the pathogenesis and the prognosis of LN, although the mechanism is yet to be understood. Anti-Ro/SSA antibodies might play an important role in the pathogenesis and prognosis in LN. However, further studies are required to understand the exact mechanism.
