Summary: A GWAS identified an association between PR3-ANCA and a SNP (rs62132293) upstream of the PRTN3 gene. The variant (G allele) was shown to be an expression quantitative trait locus in healthy controls, but its clinical impact is still unknown. Patients carrying the variant allele had elevated leukocyte PRTN3 expression compared to non-carriers, while healthy controls had low PRTN3 regardless of genotype.

Summary: This study found that recurrent or persistent ANCA patterns in patients with ANCA-associated vasculitis are associated with a higher risk of clinical relapse, while a recurrent ANCA pattern is associated with worsening renal function in patients with anti-myeloperoxidase-associated vasculitis.

Summary: In ANCA-vasculitis patients, ANCA rises often precede disease relapses within 6 months and occur less frequently within 12 months, while they are not indicative of concurrent relapses. Once a relapse is diagnosed, ANCA is significantly more often present than not.

Summary: This study found that the glycosylation changes of IgG are associated with disease flares in patients with ANCA-associated vasculitis. In addition, among the glycosylation changes, alterations in Fc bisection and fucosylation levels of IgG are correlated with long-term treatment outcome and impending relapse.

Summary: According to the study, the different ANCA serotypes in Chinese AAV patients have no impact on the likelihood of induced remission, patient survival, or disease recurrence. Younger patients with milder kidney involvement and lower disease assessment scores tend to have a better prognosis.

Summary: Protein-losing enteropathy (PLE) is a rare complication of ANCA-associated vasculitis (AAV), with only limited reports on the clinical characteristics. Patients with PLE in AAV tend to have more frequent hypocomplementemia. Although hypoalbuminemia may improve with treatment, the improvement is slow in most cases.

Summary: Testing for ANCA is crucial in diagnosing AAV, with immunoassays showing high sensitivity for PR3 and MPO antibodies. Furthermore, the specificity for c-ANCA tested by IIF is also high. This supports the recommendation to prioritize immunoassays for primary anti-PR3 and anti-MPO screening in the diagnostic workup of AAV, without the need for IIF ANCA testing.

Summary: This study aimed to develop relapse and infection risk prediction models for patients with ANCA-associated vasculitis receiving rituximab maintenance therapy. While the models lacked the power to discriminate risk between individual patients, they were able to assign patients into risk groups, which may help guide decisions regarding the potential benefit of ongoing rituximab treatment. Prospective multi-centre validation studies are recommended before using these prediction models in practice.

Summary: This study found that the presence and type of antineutrophil cytoplasmic antibody (ANCA) determine different diseases based on clinical phenotypes, renal involvement, and response to treatment. Despite the increased rate of relapses in patients with PR3-ANCA, the renal function outcome is similar.

Summary: By evaluating biomarkers related to kidney fibrosis, we can predict the outcome of patients with IgA nephropathy (IgAN). Clinical parameters and histological findings can be used to predict the kidney outcome. Biomarkers of collagen and laminin turnover in serum and urine can significantly differentiate IgAN patients with a worse prognosis.

Summary: This study aims to assess factors associated with hypogammaglobulinemia in AAV patients treated with rituximab, and the results showed that hypogammaglobulinemia is common in AAV patients treated with rituximab, and lower IgG levels are associated with severe infections. Age and higher glucocorticoid doses increase the risk of hypogammaglobulinemia in these patients.

Summary: This article reviews potential therapies, namely monoclonal antibodies, that may affect the main axis of pathogenesis of IgA nephropathy with a discussion of their potential impact on the outcome of IgAN. The new treatment options are aimed at the immunopathogenesis of IgAN, including depletion or modulation of Gd-IgA1 producing B cells, plasma cells, alternate or lectin pathway of complement. Monoclonal antibodies may target both B cells and T cells and also the factors needed for their activation and survival, e.g. BAFF or APRIL.

Summary: Alport syndrome (AS) is a genetic kidney disease caused by mutations in COL4A3, COL4A4, or COL4A5 genes. It is characterized by hematuria, proteinuria, and kidney failure. Current treatment options are limited, but RAS inhibitors and SGLT-2 inhibitors show promise. Ongoing studies are exploring the use of combined receptor inhibitors and lipid-lowering agents. Molecular genetic diagnosis is crucial for prognosis and future therapies.

Summary: This study aimed to compare levels of uric acid (UA), allantoin, and allantoin/UA ratio in serum and cerebrospinal fluid (CSF) between de novo Parkinson's disease (PD) patients and controls, and evaluate their associations with clinical severity and substantia nigra degeneration. The results showed that serum allantoin and allantoin/UA ratio were significantly increased in PD patients. The allantoin/UA ratio in serum and CSF was associated with autonomic dysfunction and presence of rapid eye movement sleep behavior disorder (RBD).

Summary: This study aimed to analyze the prevalence of heart failure and its phenotypes in patients on chronic hemodialysis. The most common phenotype of heart failure in these patients was heart failure with preserved ejection fraction (HFpEF), followed by high-output heart failure. Patients with HFpEF were older and had increased hydration and higher filling pressures in both ventricles.

Summary: Kidney fibrosis, a characteristic of chronic kidney disease, can be assessed by measuring different biomarkers of collagen type III. In this study, three collagen type III biomarkers were measured in serum and urine samples of IgA nephropathy patients. The results showed that these biomarkers provided different information about fibrotic burden and had different correlations with the degree of fibrosis in kidney biopsies. Measuring different fragments of the same ECM protein in different matrices can provide valuable insights into pathological kidney tissue alterations in patients with IgA nephropathy.

Summary: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides are a group of diseases characterized by necrotizing inflammation of small vessels. Different subgroups of AAV, including GPA, MPA, and EGPA, are defined based on clinical features. Renal involvement is common in AAV, especially in MPA. The prognosis of untreated AAV is poor, but with appropriate immunosuppressive therapy, the 5-year renal survival rate can reach 70-75%. Challenges in the management of AAV include improving disease activity measures, determining optimal therapy duration, and exploring targeted therapies with fewer adverse effects.
