<p>Lupus nephropathy is a glomerular lesion and one of the most severe organ localizations of systemic lupus erythematosus (SLE).

Arterial hypertension was present for 2 years with BP values up to 200/90 mm Hg, as well as newly diagnosed diabetes mellitus which was insulin-treated due to the low renal function. The test for anti-dsDNA-63.3 was positive and ANA titers were 1: 320. The renal biopsy revealed a combination of lupus nephropathy and a nodular variant of diabetic nephropathy. Treatment with methylprednisolone, cyclophosphamide and heparin was initiated. This was followed by improvement in serum creatinine and proteinuria, by reduction of edema, decreased titers of anti-dsDNA and by improvement of the general well-being.

Lupus nephropathy is a glomerular lesion and one of the most severe organ localizations of systemic lupus erythematosus (SLE).
