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.

A chest x-ray should be done in individuals found to have low levels of complement system proteins and breathing problems. Nov 10, 2015 1. 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. 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. 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.

Hypocomplementemic urticarial vasculitis or systemic lupus.. C1q Nephropathy Causes, Symptoms, Diagnosis, Treatment.. Mar 18, 2016 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. Some authors also refer to “lupus-like” nephropathy as “C1q nephropathy” in cases of FHN with dominant C1q staining. However, in C1q nephropathies, C1q deposits are specifically localized in the mesangial area of the glomeruli, which was not the case for patients in our series. 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.
