DelveInsight’s ’Complement 3 Glomerulopathy (C3G) - Epidemiology Forecast – 2030’ report delivers an in-depth understanding of the disease, historical and forecasted Complement 3 Glomerulopathy (C3G) epidemiology in the United States, EU5 (Germany, Spain, Italy, France, and United Kingdom) and Japan.
Complement 3 Glomerulopathy (C3G) Understanding
The term complement 3 glomerulopathy (C3G) was adopted by expert consensus in 2013 to define a group of rare kidneys diseases driven by dysregulation of the complement cascade. The major features of C3G include high levels of protein in the urine (proteinuria), blood in the urine (hematuria), reduced amounts of urine, low levels of protein in the blood, and swelling in several areas of the body.
C3G is a type of glomerular disease, characterized by predominant C3 complement component (C3) deposits in the glomeruli in the absence of a significant amount of immunoglobulin and without deposition of C1q and C4. The accumulation of C3 without a significant amount of classical or lectin complement component in the glomeruli suggests dysregulation of the alternative complement pathway as the underlying pathogenetic mechanism. This finding, in the absence or near absence of immunoglobulin deposits in a patient with the classic clinical features of glomerulonephritis, is the single diagnostic criterion. The rarity of C3G makes it challenging to derive precise incidence and prevalence of the indication; however, several small cohort studies have generated estimates of limited reliability.
The term C3G includes dense deposit disease (DDD) and C3 glomerulonephritis (C3GN), which are the two patterns of damage and inflammation in the glomeruli. In other words, the damage and inflammation in the kidney tissue in DDD appear different from that in C3GN when observed under a microscope. People with DDD generally present at a younger age (childhood or adolescence) compared to people with C3GN (adulthood).
The classification and nomenclature of this indication have drastically evolved over the years. Therefore, it is crucial to know the history of the naming system for C3G because some patients who were diagnosed with the disease before the new classification proposed in 2013 were introduced to know their disease by a different name. Before 2013, a portion of C3G patients carried the diagnosis of “membranoproliferative glomerulonephritis (MPGN)” or “mesangio proliferative glomerulonephritis.” These same patients are now referred to as C3G patients based on the microscopic appearance of their glomeruli and the new definition of the disease.
Dysregulation of the complement alternative pathway, driven by acquired and/or genetic defects, plays a pathogenetic role in C3G. The most common acquired drivers of C3G are the C3 nephritic factors (C3NeFs), heterogeneous autoantibodies that stabilize the C3 convertase, C3bBb. Although present in many different disease conditions and reported in normal individuals, most DDD patients (80–85%) and many C3GN patients (_50%) develop these autoantibodies, which prolong convertase half-life and promote fluid-phase AP dysregulation. In both DDD and C3GN, the profile of serological complement biomarkers is consistent with over-activity of the AP and terminal pathway (TP).
