C3 glomerulonephritis (C3GN), which forms a subgroup of C3 glomerulopathy (C3G), is a term coined for glomerular diseases characterized by the accumulation of complement C3 with the absence or only a trace amount of immunoglobulin deposition in the glomeruli and is the result of dysregulation in the alternative pathway of the complement system. 1 In the following years, the etiology, pathology, and prognosis of C3G were largely clarified, and the old classification of membranoproliferative glomerulonephritis (MPGN) in 3 different subclasses (type I, II, and III) was abandoned. C3 glomerulopathy (C3G) describes a pathologic pattern of injury diagnosed by renal biopsy. Kaplan-Meier curves for treated and untreated patients analyzed using log-rank tests. Membranous-like glomerulonephritis with masked IgG-kappa deposits – Routine IF shows C3 deposition without significant Ig deposition C3 glomerulopathy is a rare disease characterized by activation of the alternative complement cascade and deposition of the third component of complement without any immunoglobulin deposits in the glomeruli of the kidney. In August 2012, an invited group of experts (comprising the authors of this document) in renal pathology … While the three MPGN types stain positive for C3 (complement component 3) consistent with complement activation, as early as the 1970s it was observed that C3-positive but immunoglobulin-negative examples of MPGN I and MPGN III exist. Up to 15% progress to end-stage renal disease. Abbreviations: C3GN, C3 glomerulonephritis; C3NeF, C3 glomerulonephritis (60% vs 5% (C3 Controls) p<0.

Let’s review this case. Low serum C3 is present in 70%−80% of patients with DDD and 50% with C3GN . Complement serology, specifically low serum C3 levels and normal serum C4 levels, is crucial for the diagnosis of DDD. Classically, MPGN has a membranoproliferative-type pattern, but other morphologies have also been described depending on the time course and phase of the disease. , 1 and confirm our previously published data. C3 glomerulopathy is a recently introduced pathological entity whose original definition was glomerular pathology characterized by C3 accumulation with absent or scanty immunoglobulin deposition. 1 This umbrella term encompasses both dense deposit disease (DDD, formerly known as membranoproliferative glomerulonephritis [MPGN] type 2) and C3 glomerulonephritis (C3GN, formerly known as MPGN type 1 Significant differences were observed in serum creatinine elevations of 50% (sCr × 1. Acquired or genetic alterations of the regulatory proteins of the complement … Some pathologists believe that there are characteristic electron microscopic appearances in non-dense deposit disease C3 glomerulopathy. Differential diagnosis. Pathogenesis of both diseases is due to complement dysregulation in the alternative pathway. After kidney transplantation, disease recurrence occurs in the majority of grafts and is the predominant cause of graft failure in 50%–90% of transplant recipients ( 10 , 19 , 22 – 27 ). Patients with renal biopsy-proven C3 glomerulonephritis and detectable serum and/or urine monoclonal immunoglobulin from 2006 to 2018 in Peking University First Hospital were included, their clinical data, renal pathology type, treatment, and prognosis were collected and analyzed.

Patients who would benefit most from this treatment are not yet well defined. 3 Patients with a trend to low C3 levels, without hypocomplementemia per se, present with more crescentic lesions, more C3 deposition on kidney histopathology, and have worse renal prognosis. The C3 Nephritic Factor autoantibody stabilizes C3-convertase, which may lead to an excessive activation of complement. Acquired or genetic alterations of the regulatory proteins of the complement pathway result in C3G. [7] [8] Type 3 MPGN, which is caused by immune complex deposition in the subepithelial space.

Because these patients are generally young, the majority will be listed for kidney transplantation (KTx). Therefore, the lesion is defined by its complement-mediated pathogenesis as much as its histological pattern. Complement dysregulation underlies the observed pathology, a causal relationship that is supported by well described studies of genetic and acquired drivers of disease.

In children, the clinical presentation with pharyngitis, macroscopic hematuria, and hypocomplementemia may resemble post-streptococcal glomerulonephritis, and also, the histological picture of these two diseases is similar. Sep 17, 2024 · Importantly, C3G requires diagnosis by histopathology; more specifically, C3G diagnosis relies on renal biopsy demonstrating evidence of glomerulonephritis 34, 35 with sole or dominant glomerular immunofluorescence staining for C3 of at least two orders of magnitude greater intensity than for any other immune reactant. A subset of patients may have clinical and biochemical characteristics compatible with an autoimmune disorder. 02), these deposits were amorphous in nature (50% vs 5% respectively p=0. 01). The diagnosis of C3 glomerulopathy is established by renal biopsy and requires a C3 dominant pattern on immunofluorescence in a patient with active glomerulonephritis.

With acute glomerulonephritis associated with staphylococcal infection, the patient is more likely to be a middle-aged or older male, often diagnosed with diabetes mellitus. The prognosis (outlook) for C3 glomerulopathy can be different for each person. However, due to its high clinical variability, these criteria may not be accurate enough in some clinical scenarios. 007). , Kidney International Reports, June 2021, DOI: 10. Although quite variable among affected patients, the renal histologic appearance of C3 glomerulopathy by light microscopy is frequently that of the membranoproliferative Avacopan, an anti-C5aR, recently showed comparable efficacy to corticosteroid therapy in antineutrophil cytoplasmic antibodies-associated vasculitis (AAV). A. Although a minority of patients may present with nephrotic syndrome, about half present with hypertension and impaired glomerular filtration rate. Individuals with C3G typically present with Because the clinical presentation of C3 GP in its different forms may vary from asymptomatic hematuria to nephrotic syndrome and acute kidney injury, a diagnosis of C3 GP should be taken into consideration virtually in all patients presenting features of glomerulonephritis (proteinuria, hematuria, renal failure, or active urine sediment). Although the two disorders cause similar kidney problems, the features of dense deposit disease tend to appear earlier than those of C3 glomerulonephritis, usually in adolescence.
