A Rare Case of Double Antibody-Positive Rapidly Progressive Glomerulonephritis: A Therapeutic Challenge.

J Investig Med High Impact Case Rep 2021 Jan-Dec;9:23247096211013193

Florida State University, Sarasota, FL, USA.

Crescentic glomerulonephritis, also known as rapidly progressive glomerulonephritis, is a syndrome characterized by progressive and rapid deterioration of renal function over the course of weeks to months. Oliguria, hematuria, azotemia, and hypertension are characteristic features of this condition. Crescentic glomerulonephritis is further classified according to the staining pattern on immunofluorescence. Read More

Department of Pathology and Oncology, School of Medicine, University of Occupational and Environmental Health, 1-1 Iseigaoka, Yahatanishi-ku, Kitakyushu, Fukuoka, Japan.

Microscopic polyangiitis (MPA) is a type of necrotizing vasculitis associated with high levels of myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA). While generally associated with renal dysfunction, MPA can also cause intraabdominal hemorrhage in rare cases. A 66-year-old man was admitted to our hospital for renal dysfunction, numbness, and weight loss for 3 months. Read More

Proteinuria Indicates Decreased Normal Glomeruli in ANCA-Associated Glomerulonephritis Independent of Systemic Disease Activity.

J Clin Med 2021 Apr 6;10(7). Epub 2021 Apr 6.

Department of Nephrology and Rheumatology, University Medical Center Göttingen, 37075 Göttingen, Germany.

Background: Renal involvement is a common and severe complication of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), potentially resulting in a pauci-immune necrotizing and crescentic ANCA glomerulonephritis (GN) with acute kidney injury (AKI), end-stage renal disease (ESRD) or death. There is recent evidence that the degree of proteinuria at diagnosis is associated with long-term renal outcome in ANCA GN. Therefore, we here aimed to systematically describe the association between proteinuria and clinicopathological characteristics in 53 renal biopsies with ANCA GN and corresponding urinary samples at admission.

ANCA-Associated Vasculitis: An Update.

J Clin Med 2021 Apr 1;10(7). Epub 2021 Apr 1.

Department of Medicine, University of Cambridge, Cambridg CB2 0QQ, UK.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) represents a group of small vessel vasculitides characterized by granulomatous and neutrophilic tissue inflammation, often associated with the production of antibodies that target neutrophil antigens. The two major antigens targeted by ANCAs are leukocyte proteinase 3 (PR3) and myeloperoxidase (MPO). AAV can be classified into 3 categories based on patterns of clinical involvement: namely, granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic GPA (EGPA).

Unique Presentation of Microscopic Polyangiitis: Hearing and Vision Loss, Dysphagia, and Renal Dysfunction.

Cureus 2021 Mar 23;13(3):e14069. Epub 2021 Mar 23.

Department of Internal Medicine, University of Texas Southwestern Medical Center, Dallas, USA.

Microscopic polyangiitis (MPA) is an autoimmune small-vessel vasculitis often positive for perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA), or anti-myeloperoxidase (MPO), that classically affects the lungs, kidneys, and skin. Several atypical presentations of MPA involving other organs have also been reported in the literature. We report a unique case of a patient who presented with rare presentations of MPA: hearing and vision loss, dysphagia, renal dysfunction. Read More

Kidney Int 2021 Apr 20. Epub 2021 Apr 20.

Department of Pathology, Columbia University Irving Medical Center, New York, New York, USA.

Hydralazine, a widely used therapy for hypertension and heart failure, can elicit autoimmune disease, including anti-neutrophil cytoplasmic antibody associated glomerulonephritis (ANCA-GN). We identified 80 cases of ANCA-GN complicating treatment with hydralazine, accounting for 4.3% (80/1858 biopsies) of ANCA-GN diagnosed between 2006 and 2019. Read More

Division of Nephrology, Department of Internal Medicine, Jichi Medical University, Tochigi, Japan.

A 70-year-old man presented with proteinuria, microscopic hematuria, and an increased level of serum creatinine. A systemic workup revealed that the patient had bronchogenic carcinoma and anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis concurrently. Despite the increase in the cumulative number of publications on paraneoplastic glomerulopathies, an awareness of the link between cancer and ANCA-associated glomerulonephritis is lacking. Read More

Rapidly progressive IgA vasculitis-associated nephritis successfully treated with immunosuppressive therapy in an adolescent with chronic granulomatous disease.

CEN Case Rep 2021 Mar 8. Epub 2021 Mar 8.

Department of Nephrology and Dialysis, Hyogo Prefectural Amagasaki General Medical Center, 2-17-77 Higashinaniwa-cho, Amagasaki, Hyogo, 660-8550, Japan.

Chronic granulomatous disease (CGD) is a rare immunodeficiency disorder with genetic defects in the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex in phagocytes, leading to recurrent severe infections and granuloma formation. Genitourinary involvement, including obstructive granulomas, infections, nephrotoxicity of anti-infective agents, and amyloidosis, is frequently observed in patients with CGD, whereas the clinical and pathological details of the less commonly reported glomerular disease remain obscure. Here, we report the case of a patient with CGD who developed rapidly progressive IgA vasculitis-associated nephritis (IgAVN) and review the literature on biopsy-proven glomerular diseases in patients with CGD.

Heightened Crescentic Glomerulonephritis in Immune Challenged 129sv Mice Is TGF-β/Smad3 Dependent.

Int J Mol Sci 2021 Feb 19;22(4). Epub 2021 Feb 19.

The Department of Biomedical Engineering, University of Houston, Houston, TX 77204-5060, USA.

The 129sv mouse strain is particularly sensitive to experimental immune-mediated nephritis. Previous studies have indicated that transforming growth factor-β (TGF-β) plays a critical role in both immune modulation and tissue fibrogenesis in various diseases and that its biological activities are exerted via the SMAD family. In this study, we aimed to determine whether TGF-β/SMAD signaling is essential for the development of immune-mediated nephritis in 129sv mice. Read More

Immunoglobulin-A Vasculitis With Renal Involvement in a Patient With COVID-19: A Case Report and Review of Acute Kidney Injury Related to SARS-CoV-2.

Can J Kidney Health Dis 2021 5;8:2054358121991684. Epub 2021 Feb 5.

Department of Medicine, Division of Nephrology, University of Calgary, AB, Canada.

Rationale: Acute kidney injury is a common complication of COVID-19 and is associated with significantly increased mortality. The most frequent renal biopsy finding with SARS-CoV-2 infection is acute tubular injury; however, new onset glomerular diseases have been reported. The development of persistent urinary abnormalities in patients with COVID-19 should prompt consideration for renal biopsy to rule out glomerulonephritis. Read More

Division of Translational Immunology, III. Department of Medicine, University Medical Center Hamburg-Eppendorf, Martinistr. 52, 20246, Hamburg, Germany.

CD4 T cells are key drivers of autoimmune diseases, including crescentic GN. Many effector mechanisms employed by T cells to mediate renal damage and repair, such as local cytokine production, depend on their presence at the site of inflammation. Therefore, the mechanisms regulating the renal CD4 T cell infiltrate are of central importance. Read More
