IgA Nephropathy

Findings from this retrospective study help address challenges in distinguishing immunoglobulin A nephropathy from immunoglobulin A vasculitis-associated nephritis, overcoming their shared pathogenetic features.

Hydroxychloroquine and leflunomide were found to be safe and effective for treating IgAN, with study results showing the use of both immunosuppressants in combination with a renin-angiotensin system inhibitor proved most effective in improving proteinuria and stabilizing renal function.

Obesity was linked to an increased risk of focal segmental glomerulosclerosis and hypertensive nephropathy, with further analysis revealing its impact on the risk of developing end-stage kidney disease.

In the wake of Vera Therapeutics announcing positive 72-week data from the phase 2b ORIGIN trial, we sat down with lead investigator Richard Lafayette, MD, to learn more about how he interprets the latest data from the atacicept program in IgA nephropathy.

The 72-week open-label extension of the phase 2b ORIGIN trial reveals atacicept's potential as a disease-modifying treatment for IgA nephropathy, showing eGFR stabilization and improvements in key indicators

Results called attention to suboptimal blood pressure and proteinuria control as well as a lack of maximal RAASI dosing in a cohort of adult patients with IgAN from the Cure Glomerulonephropathy Network study.

Findings from the retrospective cohort study suggest an increased prevalence of advanced kidney disease among individuals with Crohn disease and ulcerative colitis.

Geovanni Faddoul, MD, discusses findings from his recent study examining the impact of induction and maintenance therapy on IgAN recurrence, graft survival, and mortality in kidney transplantation.

Patients with IgAN and urine protein levels of 0.75–3.5 g/d treated with corticosteroids exhibited significantly greater overall and complete remission rates compared to those who received supportive care.

Renal failure risk group classification based on pathological findings from patients’ kidney biopsy, eGFR, and proteinuria was significantly associated with a composite 50% increase in serum creatinine.

Findings suggest serum C3 may be a viable biomarker for the occurrence and prognosis of IgAN, highlighting the role of the complement system in the disease’s pathogenesis.

Results of the retrospective study suggested blood pressure, serum IgA, potassium, and segmental glomerulosclerosis may be predictive of the rapid progression of renal endpoints in patients with concurrent IgAN and membranous nephropathy.

Adult patients with IgAV required dialysis sooner and had shorter survival time compared to patients with IgAN.

Younger age at the time of kidney transplantation, faster progression to end-stage renal disease, a history of kidney transplantation, and no induction therapy were associated with IgAN recurrence, which was linked to poorer graft survival.

Budesonide is the first treatment to receive approval from the FDA for reducing the loss of kidney function in adults with primary IgAN.

The 3-year and 5-year renal survival rates did not exhibit significant changes, but IgAN's 10-year renal survival has shown gradual decreases since the 1990s.

In the new study, 71% of the patients who developed gross hematuria after a COVID-19 vaccination were females, and for 92% of the patients, the investigators observed gross hematuria had developed after the second or subsequent vaccinations.

New data shows one-quarter of patients with kidney disease associated with IBD progress to end-stage disease, with primary determinants including age and baseline eGFR.

Investigators reported that AI programs such as LightGBM could potentially significantly benefit the diagnosis of Berger disease.

Advanced kidney disease, type 2 diabetes, and high risk of disease progression were prevalent among the cohort based on records collected from the HealthVerity database.

Part 1 of the study evaluates reduction in urine protein: creatinine ratio, and part 2 of the study evaluates the number of patients achieving complete remission when on the bruton tyrosine kinase inhibitor for primary membranous nephropathy.

Results highlighted an association between socioeconomic deprivation and greater risk of progression to kidney failure in patients with IgAN.

The ravulizumab group had a proteinuria reduction of 40.3% while the placebo group had a reduction of 10.9% by week 26, highlighting ravulizumab’s effectiveness in treating patients with IgA Nephropathy.

Joanthan Barratt, MD, discusses the results of a RaDaR analysis aimed at examining trends in time-averaged proteinuria and eGFR slope in patients with IgA nephropathy.

Data for a pair of studies presented at Kidney Week 2023 provide an overview of the effects of eGFR and how this might translate to potential long-term benefit in patients IgA nephropathy.
