It is histologically defined and poorly understood. Light microscopic features are heterogeneous and comprise minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), and proliferative glomerulonephritis.

C1q Nephropathy is one of the many diseases causing Nephrotic Syndrome. C1q is a normal protein of the immune system and is found throughout the circulatory system. In an individual with C1q Nephropathy the protein is also found deposited in the the kidneys. Introduction. C1q nephropathy is a rare form of glomerulopathy first described as a distinct clinic-pathological entity by Jennette and Hipp in 1985 definition is histological and comprises 1 characteristic deposition of C1q in the renal mesangium in a dominant or codominant fashion and 2 the absence of clinical or immunological features of systemic lupus erythematosus SLE. Hypertension and renal insufficiency at the time of diagnosis are common findings. Clinical presentation is also diverse, and ranges from asymptomatic hematuria or proteinuria to frank nephritic or nephrotic syndrome in both children and adults.

C1q Nephropathy The Unique Underrecognized Pathological.. Hypocomplementemic urticarial vasculitis or systemic lupus.. C1q nephropathy, first described by Jennette and Hipp in 1985, is a pattern of glomerulonephritis characterized by predominant mesangial C1q deposition but with other histological features resembling lupus nephritis, although no extrarenal disease 1–4. In this report, we describe our experience of C1q nephropathy. ConfigCtrl2metaDescription}} INTRODUCTION. In addition to minimal change disease MCD, three other disorders usually present with the nephrotic syndrome and may also show only minor changes on light microscopy idiopathic mesangial proliferative glomerulonephritis; immunoglobulin M IgM nephropathy; and C1q nephropathy. Immunofluorescence showed mild mesangial staining for IgA, IgG, IgM and complement factor C3. Immunostaining for complement factors C4 and C1q, κ and λ light chains, and fibrinogen was negative. Methylene blue-stained thin sections cut at 1 µm were prepared for electron microscopy and contained one glomerulus and arteriole.
