    IgA-glomerulonephritis, a common kidney disease, often has a poor prognosis, with many patients developing renal insufficiency. Predictors of an unfavorable course include male gender, proteinuria, hypertension, and specific histological changes.

    Area of Science:

    • Nephrology
    • Immunology
    • Pathology

    Context:

    • IgA-glomerulonephritis (IgA-GN) is the most common form of glomerulonephritis, accounting for 20% of cases.
    • Contrary to existing literature, this study suggests IgA-GN may not have a benign prognosis.
    • Renal insufficiency developed in 34% of investigated patients within 4-96 months.

    Purpose:

    • To investigate the prognosis and diagnostic/prognostic markers of IgA-glomerulonephritis.
    • To compare findings with existing literature regarding IgA-GN outcomes.
    • To identify clinical and histological factors associated with unfavorable renal outcomes in IgA-GN patients.

    Summary:

    • Renal insufficiency developed in 17 out of 50 patients, with 3 requiring dialysis.
    • Unfavorable outcomes were predictable in male patients, those with proteinuria, hypertension, age over 30, and specific histological findings (glomerulosclerosis, tubular atrophy, interstitial fibrosis, vascular lesions).

  • Increased serum IgA, IgA complexes, HLA associations, hematuria, dysuria, and kidney pain were not reliable diagnostic or prognostic indicators. Skin biopsy had limited diagnostic value.

    • Impact:

    • Identifies key predictors of poor prognosis in IgA-GN, enabling earlier intervention and tailored patient management.
    • Challenges the notion of a benign prognosis for IgA-GN, highlighting the need for closer monitoring.
    • Suggests that focusing on clinical and histological factors, rather than serological markers or skin biopsy, may be more beneficial for predicting IgA-GN progression.
