Disease relevance of IGAN

  • We have evaluated its role in both initiation and/or progression of primary immunoglobulin A (IgA) nephropathy (IGAN) in a case-control study involving a prospective cohort of 318 IGAN patients and a matched group of 294 controls [1].
  • The aim of this open prospective trial was to evaluate the efficacy and safety of low-dose immunoglobulin therapy in moderate IGAN and HSP with permanent proteinuria [2].
  • IGAN patients with macroscopical hematuria (macro-H) differ from the other IGAN patients in 9 aspects: history, HLA-DR, Gm-allotypes, actuarial kidney survival, initial creatinine clearance, initial proteinuria, initial microhematuria, age at presentation and light microscopy of the renal biopsy [3].
  • We review the literature on the association of IGAN with psoriasis and discuss the likely pathogenetic linkage [4].
  • Fourteen patients with moderate IGAN [idiopathic IGAN: n = 11; chronic idiopathic HSP: n = 3] and permanent albuminuria were treated with polyvalent IMIG (16.5%) for 9 months (0.35 ml/kg once a week for 1 month, followed by 0.35 ml/kg every 15 days for a further 8 months) [2].

Chemical compound and disease context of IGAN

 

Biological context of IGAN

  • The d32-CCR5 polymorphism played a significant role in the progression of primary IGAN, with the nl/nl genotype being an independent protective factor for late progression towards ESRF/dialysis [1].
  • The d32 allele frequency was not different in patients (11.0%) vs controls (8.3%), indicating no significant influence on IGAN initiation [1].
  • IGAN patients had the highest graft survival rate [16].
  • No single HLA haplotype or antigen was found in all the patients with IgA nephropathy [17].
  • In addition, dysfunction of the ASGR or altered N-linked glycosylation, but not O-glycans, that affects recognition by this receptor may account for the elevated serum IgA seen in liver disease and IgA nephropathy [18].
 

Anatomical context of IGAN

 

Associations of IGAN with chemical compounds

  • Circulating immune complexes (CIC) containing IgA and C3 were elevated in 48% of IgA nephropathy patients; IgA1 was the predominant subclass [24].
  • Role of the deletion of polymorphism of the angiotensin converting enzyme gene in the progression and therapeutic responsiveness of IgA nephropathy [25].
  • In this study, among patients with biopsy-proven IgA nephropathy, 53 patients in whom creatinine clearance had been monitored over 5 yr were recruited for study [25].
  • Circulating immune complexes in IgA nephropathy consist of IgA1 with galactose-deficient hinge region and antiglycan antibodies [26].
  • INTERPRETATION: A 6-month course of steroid treatment protected against deterioration in renal function in IgA nephropathy with no notable adverse effects during follow-up [27].
 

Physical interactions of IGAN

  • We report here an additional significant association between IgA nephropathy and an SNP located in the gene encoding immunoglobulin micro-binding protein 2 (IGHMBP2) at chromosome 11q13.2-q13 [28].
  • However, studying the functional aberration in the human IgA, CD89, and CD71 complex formation in pathogenesis of IgA nephropathy is hard [29].
  • The presence of fibronectin in the circulating aggregates may play an important role in the preferential deposition of nephritogenic IgA-containing immune complexes in the mesangium of patients with IgA nephropathy [30].
  • We studied serum IgA as antibodies to dietary antigens (Ag), as lectin-binding molecules, and as conglutinin-binding immune complexes (IgAIC) in people from geographical areas in which IgA nephropathy (IgAGN) is particularly frequent [31].
