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.

Feb 02, 2017 The presence of anti-C1q antibodies although this test is not widely available Additional laboratory studies may include tests for kidney function tests and immunological status. A chest x-ray should be done in individuals found to have low levels of complement system proteins and breathing problems. Teenagers and young adults, higher incidence among blacks and females. Presents as nephrotic syndrome, renal insufficiency or hematuria. Collapsing C1q nephropathy with rapid progression to end stage renal disease appears to reside in the MYH9 associated disease spectrum Am J Kidney Dis 2010;55e21 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 is a relatively rare cause of proteinuria and nephrotic syndrome that can mimic FSGS clinically and histologically. The diagnosis is based on the presence of mesangial immune complex deposits that have conspicuous staining for C1q accompanied by staining for IgG, IgM, and C3. Complement Component C1q - an overview ScienceDirect Topics. Pathology Outlines - C1q nephropathy. Proliferative lupus nephritis in the absence of overt.. 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. C1q deficiency is a rare disorder associated with recurrent skin lesions, chronic infections, systemic lupus erythematosus SLE or SLE-like diseases. It has also been associated with a kidney disease known as mesangial proliferative glomerulonephritis. C1q is a protein and together with other proteins, C1r and C1s, it forms the C1 complex. The 2 patients presented here showed the typical signs of hypocomplementemic urticarial vasculitis syndrome HUVS. During follow-up, there was an inverse correlation between anti-C1q autoantibody titer and C1q antigen concentration in serum in both patients over a period of 2 years.
