Design, synthesis and pre-clinical characterization of selective Factor D inhibitors targeting the alternative complement pathway.

J Med Chem 2019 Apr 17. Epub 2019 Apr 17.

Complement Factor D (FD), a highly specific S1 serine protease, plays a central role in the amplification of the alternative complement pathway (AP) of the innate immune system. Dysregulation of AP activity predisposes individuals to diverse disorders such as age-related macular degeneration (AMD), atypical hemolytic uremic syndrome (aHUS), membranoproliferative glomerulonephritis type II (MPGNII) and paroxysmal nocturnal hemoglobinuria (PNH). Previously, we have reported the screening efforts and identification of reversible benzylamine-based FD inhibitors (1 and 2) binding to the open active conformation of FD. Read More

Multiple Faces of Chronic Lymphocytic Leukaemia: A Patient with Renal, Cardiac, and Skeletal Complications.

Case Rep Nephrol 2019 12;2019:5390235. Epub 2019 Mar 12.

Department of Renal Medicine, Norfolk and Norwich University Hospital, Norwich, UK.

We describe a patient who had chronic lymphocytic leukaemia (CLL) Binet stage A at presentation with further evidence of disease at multiple sites but who initially required no treatment. However, several years later, her peripheral blood lymphocyte count started to increase, and soon after that she suffered an acute myocardial infarct (in the absence of coronary atheroma) together with proteinuric renal failure due to membranoproliferative glomerulonephritis. Her renal function improved markedly following anti-CLL chemotherapy. Read More

Role of CD8+ T cells in crescentic glomerulonephritis.

Nephrol Dial Transplant 2019 Mar 16. Epub 2019 Mar 16.

Department of Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, USA.

Crescentic glomerulonephritis (cGN) comprises three main types according to the pathogenesis and immunofluorescence patterns: anti-glomerular basement membrane antibody cGN, vasculitis-associated cGN and post-infectious immune complex cGN. In this brief review of the immune-pathogenesis of cGN, the focus is mainly on the role of CD8+ T cells in the progression of cGN. Under control conditions, Bowman's capsule (BC) provides a protected immunological niche by preventing access of cytotoxic CD8+ T cells to Bowman's space and thereby podocytes. Read More

[Membranoproliferative glomerulonephritis and C3 glomerulopathy].

Internist (Berl) 2019 Mar 11. Epub 2019 Mar 11.

Klinik für Nieren- und Hochdruckerkrankungen, Medizinische Hochschule Hannover, Hannover, Deutschland.

Based on an increasingly better pathophysiological understanding over the last 10 years, in 2010 a new classification of glomerulonephritis with dominant or codominant C3 deposits was introduced and the predominant subgoup was termed C3 glomerulopathy (C3G). In the current classification, immune complex mediated membranoproliferative glomerulonephritis (IC-MPGN) and C3 glomerulopathy (C3G) form a disease spectrum which is very heterogeneous in terms of pathophysiology and the clinical course. Recent evidence suggests that IC-MPGN and C3G share more pathophysiological aspects with respect to secondary causes, autoantibodies and genetic aspects than had been suggested with the creation of the new classification.

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.

Unraveling the Molecular Mechanisms Underlying Complement Dysregulation by Nephritic Factors in C3G and IC-MPGN.

Front Immunol 2018 15;9:2329. Epub 2018 Oct 15.

Clinical Research Center for Rare Diseases Aldo e Cele Daccò and Centro Anna Maria Astori, Science and Technology Park Kilometro Rosso, Istituto di Ricerche Farmacologiche Mario Negri IRCCS, Bergamo, Italy.

Membranoproliferative glomerulonephritis (MPGN) was recently classified as C3 glomerulopathies (C3G), and immune-complex (IC) mediated MPGN. Dysregulation of the complement alternative pathway, driven by acquired and/or genetic defects, plays a pathogenetic role in C3G. However, alternative pathway abnormalities were also found in IC-MPGN. Read More

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.

Treatment of recurrent, post-kidney transplant membranoproliferative glomerulonephritis with plasmapheresis and rituximab: A case report and literature review
.

Clin Nephrol 2019 Jan;91(1):52-58

Membranoproliferative glomerulonephritis is known to recur after kidney transplantation and may lead to allograft loss. Although an optimal treatment has not been determined, B-cell targeted therapies are now increasingly used as first-line agents, based on growing data showing antibodies as key players in the pathogenesis of membranoproliferative glomerulonephritis. Here, we report a case of recurrent immune complex-mediated membranoproliferative glomerulonephritis 3 years after a living-donor kidney transplant. Read More

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

A Case of Hepatic Glomerulosclerosis with Monoclonal IgA1- Deposits.

Case Rep Nephrol 2018 1;2018:4748357. Epub 2018 Oct 1.

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
