  • Title: [Glomerulonephritis with mesangial IgA deposit (IgA mesangiopathy?)].
    Author: Mota F, Lunar OR, Gordillo G.
    Journal: Bol Med Hosp Infant Mex; 1980; 37(6):1123-34. PubMed ID: 7470265.
    Abstract:
    Clinical correlations and evolution were studied in 34 biopsies from patients with the following diagnosis: Henoch-Schönlein purpura in 17, monosymptomatic hematuria in 11, idiopathic nephrotic syndrome in 3, and Fanconi Syndrome, Systemic lupus erythematosus and tubulointerstitial nephritis, one for each diagnosis respectively. All these biopsies showed anti-IgA mesangial deposits, by immunofluorescence techniques with variable morphology by light microscopy. Endo and extracapillary proliferation was the most frequent lesions. Twenty cases had follow-up observation for over 2 years: 7 cases were in remission, hematuria and/or proteinuria persisted in 10 and 3 cases progressed to chronic renal failure. In conclusion, mesangial IgA deposits are not an infrequent finding in renal biopsies performed in the Hospital Infantil de México. Although the predominant clinical diagnosis was either Henoch-Schönlein purpura or monosymptomatic hematuria, other diagnosis were also found. Some cases with this mesangiopathy presented as idiopathic nephrotic syndrome or post-streptococcal glomerulonephritis, but with serum complement within normal levels. Long-term prognosis was related to glomerular morphology as in other glomerulopathies.
