Introduction
Systemic lupus erythematosus (SLE) is an autoimmune disease with multisystem involvement, and Lupus nephritis (LN) typically shows immune deposits on biopsy. Pauci-immune LN is a rare entity.
Case Description
A 35 year old female presented with pedal edema, reduced urine output & yellowish discoloration of eyes since 20 days.No vomiting, dyspnea, joint pains, rashes, or hematuria. She had similar episodes in 2011 and 2013 & was given blood transfusion and oral steroids. She is a hypertensive for 10 years and diabetic for 2 years. She had 2 normal vaginal deliveries with no obstetric complications. On examination she had pallor, icterus and generalized edema, blood pressure of 170/80mmHg. Rest of the examination was normal.
She had severe anemia, renal failure, positive ANA, dsDNA and direct Coomb’s test, with normal complements. There was no evidence of active hemolysis. SLE with Auto immune hemolytic anemia (AIHA) and probable lupus nephritis (LN) was diagnosed. Steroid pulse was started with stabilization of renal function and hemoglobin.
Renal biopsy showed necrotising crescentic glomerulonephritis with no endocapillary proliferation. Immunofluorescence did not show any immune deposits. A diagnosis of pauci immune LN was made, and was started on cyclophosphamide. She had partial renal recovery with creatinine of 1.5 mg/dl, no hematuria, no hemolysis.
Discussion
Renal biopsy in SLE patients can reveal varied pathologies like ANCA or lupus vasculitis etc. In our case, renal biopsy was similar to ANCA vasculitis, however systemic features favored SLE. With a diagnosis of SLE, and absence of endocapillary proliferation, a diagnosis of pauci-immune LN was made.
