BMC Nephrol 2019 Feb 14;20(1):53. Epub 2019 Feb 14.

Department of Pathology, Division of Renal and Transplant Pathology, Ohio State University Wexner Medical Center, M018 Starling-Loving Hall, 320 W 10th Ave, Columbus, OH, 43210, USA.

Background: Proliferative glomerulonephritis with monoclonal IgG deposits (PGNMIGD) is a disease entity classified under the group of "Monoclonal gammopathy-related kidney diseases", and can recur after transplant. Clinical remission of proteinuria in patients with PGNMIGD has been previously shown following anti-B cell and/or anti-plasma cell therapies. Our case is the first to show complete histologic resolution of the glomerular monoclonal IgG kappa deposits in a case of recurrent PGNMIGD in renal allograft after rituximab and steroid treatment.

Electronic address:

Cryoglobulinemia is defined as the persistent presence in serum of abnormal immunoglobulins (Igs) that precipitate at low temperatures and dissolve again upon warming. Cryoglobulins may be composed only of a monoclonal Ig (simple type I cryoglobulinemia), of a monoclonal Ig bound to the constant domain of polyclonal Ig heavy chains (mixed type II cryoglobulinemia), or only of polyclonal Igs (mixed type III cryoglobulinemia). The manifestations of type I cryoglobulinemia are often related to intravascular obstruction, whereas those seen in the mixed cryoglobulinemias often originate in true immune complex-mediated vasculitis.

A case of aggressive atypical anti-GBM disease complicated by CMV pneumonitis.

BMC Nephrol 2019 Jan 31;20(1):29. Epub 2019 Jan 31.

Department of Pathology and Laboratory Medicine, Cumming School of Medicine, University of Calgary, Foothills Medical Center, 1403 29 St NW, Calgary, AB, T2N 2T9, Canada.

Background: Anti-glomerular basement membrane (anti-GBM) disease is characterized by circulating IgG glomerular basement membrane antibodies and is clinically expressed as a rapidly progressive crescentic glomerulonephritis (GN), with 30-60% of patients also developing pulmonary hemorrhage. Classically, the renal biopsy shows glomerular crescent formation, bright linear staining of glomerular basement membranes (GBM) for IgG on direct immunofluorescence (IF), and the serologic presence of circulating anti-GBM antibodies. Recently, patients with linear IgG IF staining, undetectable circulating anti-GBM antibodies and glomerular changes atypical for anti-GBM disease have been described as "atypical anti-GBM disease", with a distinctly more benign clinical course than typical anti-GBM disease.

Severe Eosinophilia in Myelodysplastic Syndrome With a Defined and Rare Cytogenetic Abnormality.

Front Immunol 2018 9;9:3031. Epub 2019 Jan 9.

Department of Hematology and Rheumatology, Faculty of Medicine, Kindai University Hospital, Osaka-Sayama, Japan.

Myelodysplastic syndromes (MDS) are a heterogeneous group clonal disorders of hematopoietic stem cells (HSC) characterized by ineffective hematopoiesis that lead to variable grades of impaired blood cell production. Chromosomal aberrations are often detected in MDS patients and thus cytogenetic analysis is useful for the diagnosis of these disorders. Common recurring chromosomal defects, such as the -5/5q- and -7/7q- are relatively well characterized cytogenetic abnormalities in MDS, however, the biological significance of uncommon cytogenetic alterations is unknown.

Overexpression of toll-like receptor 9 correlates with podocyte injury in a murine model of autoimmune membranoproliferative glomerulonephritis.

Autoimmunity 2018 Dec 28;51(8):386-398. Epub 2018 Dec 28.

a Laboratory of Anatomy, Faculty of Veterinary Medicine, Department of Basic Veterinary Sciences , Hokkaido University , Sapporo , Japan.

Toll-like receptors (Tlrs) are sensors of danger signals which promote the activation of immune cells and intrinsic renal cells. Podocytes, the intrinsic cells of glomerulus, are continuously exposed to various plasma solutes and danger signals due to their unique location in the glomerulus. Herein, we show that Tlr9 is overexpressed in podocytes and the mechanisms which cause its injury and development of membranoproliferative glomerulonephritis (MPGN) in model BXSB/MpJ-Yaa (Yaa) mice.

Paraffin Immunofluorescence: A Valuable Ancillary Technique in Renal Pathology.

Kidney Int Rep 2018 Nov 7;3(6):1260-1266. Epub 2018 Jul 7.

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, Minnesota, USA.

Immunofluorescence on frozen tissue is the gold standard immunohistochemical technique for evaluation of immune deposits in the kidney. When frozen tissue is not available or lacks glomeruli, immunofluorescence can be performed on paraffin tissue after antigen retrieval (paraffin immunofluorescence). Excellent results can be obtained by paraffin immunofluorescence in most immune complex-mediated glomerulonephritides and dysproteinemia-associated kidney lesions, and thus this technique has become a valuable salvage technique in renal pathology.

Complement-mediated renal diseases after kidney transplantation - current diagnostic and therapeutic options in and recurrent diseases.

World J Transplant 2018 Oct;8(6):203-219

Faculty of Health and Science, University of Liverpool, Institute of Learning and Teaching, School of Medicine, Liverpool L69 3GB, United Kingdom.

For decades, kidney diseases related to inappropriate complement activity, such as atypical hemolytic uremic syndrome and C3 glomerulopathy (a subtype of membranoproliferative glomerulonephritis), have mostly been complicated by worsened prognoses and rapid progression to end-stage renal failure. Alternative complement pathway dysregulation, whether congenital or acquired, is well-recognized as the main driver of the disease process in these patients. The list of triggers include: surgery, infection, immunologic factors, pregnancy and medications. Read More

Division of Nephrology and Hypertension, Department of Internal Medicine, The Jikei University School of Medicine, Tokyo, Japan.

Glomerular immunoglobulin A (IgA) deposition is a common finding in hepatic glomerulosclerosis; thus, this disease is also called hepatic IgA nephropathy. However, only a small number of patients with hepatic IgA nephropathy have active glomerular lesions, so functional decline is slow in most cases. In this report, we describe a 60-year-old man who developed nephrotic syndrome and progressive renal impairment during follow-up for alcoholic liver cirrhosis. Read More

BMC Nephrol 2018 Oct 4;19(1):251. Epub 2018 Oct 4.

Department of Nephrology and Endocrinology, National Defense Medical College, 3-2 Namiki, Tokorozawa, Saitama, 359-8513, Japan.

Background: The pathophysiologic role of exogenous granulocyte-colony stimulating factor (G-CSF) administration is reportedly linked to the progression of glomerulonephritis. However, the relationship between endogenous G-CSF overproduction and the progression of glomerulopathy has not been well investigated.

Case Presentation: A 76-year-old woman presented with neutrophilia at a medical check-up and thorough examination revealed a high level of serum G-CSF. Read More

Membranoproliferative glomerulonephritis in a patient with chronic brucellosis.

Kidney Res Clin Pract 2018 Sep 30;37(3):298-303. Epub 2018 Sep 30.

Department of Nephrology, University Hospital of Patras, Patras, Greece.

Brucellosis is the most common zoonotic disease in Greece, with an endemic distribution and can affect any organ. Infiltration of the renal parenchyma causes acute and chronic interstitial nephritis with granulomas, whereas renal glomeruli are rarely affected. The disease has been sporadically reported, and it causes various histopathologic patterns. Read More

An autopsy case of TAFRO syndrome with membranoproliferative glomerulonephritis-like lesions.

CEN Case Rep 2019 Feb 22;8(1):48-54. Epub 2018 Sep 22.

Department of Pathology, Kitasato University School of Medicine, Sagamihara, Japan.

TAFRO syndrome (thrombocytopenia, anasarca, myelofibrosis, renal dysfunction, and organomegaly) is an atypical manifestation of multicentric Castleman's disease. Although overproduction of interleukin-6, vascular endothelial growth factor, and other cytokines may partially explain the pathophysiology of this rare syndrome, the precise mechanisms underlying the renal dysfunction associated with the condition remain unclear. Here, we describe a case of a 69-year-old male with TAFRO syndrome. Read More

[Rapidly progressive proliferative glomerulonephritis with monoclonal immunoglobulin G deposits despite the mild histological changes. Case report].

Orv Hetil 2018 Sep;159(38):1567-1572

Patológiai Intézet, Szegedi Tudományegyetem, Általános Orvostudományi Kar Szeged.

Proliferative glomerulonephritis with monoclonal immunoglobulin G (IgG) deposits is characterized by granular deposits of monoclonal IgG; histologically it has typically a membranoproliferative or endocapillary pattern, and seen electronmicroscopically there are dense deposits without substructure. Here, we present the case of a 62-year-old Caucasian woman who was admitted with rapidly progressive kidney failure. The patient's status, the laboratory and imaging examinations did not support prerenal, postrenal and - among the intrinsic causes - vascular and tubulointerstitial origin. Read More

Mixed cryoglobulinemic membranoproliferative glomerulonephritis due to monoclonal gammopathy of undetermined significance: A case report.

Medicine (Baltimore) 2018 Sep;97(37):e12416

Division of Nephrology, Department of Internal Medicine, Shin Kong Wu Ho-Su Memorial Hospital.

Rationale: Membranoproliferative glomerulonephritis (MPGN) can be induced by autoimmune diseases, chronic infection, chronic hepatitis, and paraproteins (including cryoglobulinemia). In addition, the mixed cryoglobulinemic MPGN is reported to be highly correlated with hepatitis C virus (HCV) infection.

Patient Concerns: We reported a rare case of a 61-year-old woman without a history of viral hepatitis infection; she presented with bilateral leg edema and proteinuria. Read More

Renal Division, Brigham & Women's Hospital, Harvard Medical School, 221 Longwood Ave, Boston, MA, 02115, USA.

Background: Long-term outcomes in kidney transplantation (KT) have not significantly improved during the past twenty years. Despite being a leading cause of graft failure, glomerular disease (GD) recurrence remains poorly understood, due to heterogeneity in disease pathogenesis and clinical presentation, reliance on histopathology to confirm disease recurrence, and the low incidence of individual GD subtypes. Large, international cohorts of patients with GD are urgently needed to better understand the disease pathophysiology, predictors of recurrence, and response to therapy. Read More

UCLA David Geffen School of Medicine, Westwood, California, USA.

Hepatitis C (HCV) infection has a prevalence of 3 million infected individuals in the United States, according to recent Center for Disease Control reports, and can have various renal manifestations. Cryoglobulins, antibodies that precipitate at colder temperatures in vitro, are a relatively common cause of renal disease in HCV infection. The cryoglobulin proteins can form occlusive aggregates in small glomerular capillary lumina or deposit in other areas of the glomerulus, resulting in hypocomplementemia, proteinuria, hematuria, and renal injury.

Standardized classification and reporting of glomerulonephritis.

Nephrol Dial Transplant 2019 Feb;34(2):193-199

Division of Nephrology and Hypertension, Mayo Clinic, Rochester, MN, USA.

A kidney biopsy is done to determine the etiology of the glomerulonephritis (GN) and the severity of the lesion, to identify whether other lesions, related to or not related to the GN, are present on the kidney biopsy and finally to ascertain the extent of chronicity of the GN. The etiology of GN is based on the classification of GN into five groups: immune complex-mediated GN, antineutrophil cytoplasmic antibody (ANCA)-associated GN, anti-glomerular basement membrane (GBM) GN, monoclonal immunoglobulin-mediated GN and C3 glomerulopathy. Immune complex GN includes multiple specific diseases such as lupus nephritis, IgA nephropathy, infection-related GN and fibrillary GN. Read More
