The association between malignant tumors and the occurrence of glomerular disease has been well documented in previous studies. The most common types of malignant tumor include Hodgkin's lymphoma with minimal change glomerular nephritis, solid tumor with membranous nephropathy and renal cell carcinoma with immunoglobulin (Ig)A nephropathy. The present case study describes a case of a 31-year-old Chinese female patient who was hospitalized with chronic glomerulonephritis. The patient self-administered unknown traditional Chinese medicine; however, protein excretion/24-h remained increased compared with normal levels...

IgA nephropathy (IgAN) is characterized by predominant IgA deposition in the glomerular mesangium. It has been considered that the deposited IgA is synthesized by B cells, although recent reports have suggested the implication of other cell types. Therefore, the present study investigated whether glomerular mesangial cells could produce IgA by themselves. Semi‑quantitative reverse transcription-polymerase chain reaction, and immunostaining analysis revealed that the IgA protein and gene transcripts were expressed in primary human renal mesangial cells (HRMCs)...

Background: MicroRNAs (miRNAs) are a family of short noncoding RNAs that play important roles in posttranscriptional gene regulation. miRNAs inhibit target gene expression by blocking protein translation or by inducing mRNA degradation and therefore have the potential to modulate physiological and pathological processes. Summary: In the kidney, miRNAs play a role in the organogenesis and in the pathogenesis of several diseases, including renal carcinoma, diabetic nephropathy, cystogenesis, and glomerulopathies...

BACKGROUND: Transfusion-mediated human parvovirus B19 (PVB19) infection is rare but often causes severe hematologic disorders. In Japan, routine blood donor screening for PVB19 antigen (detection sensitivity, 10(6.4) IU/mL) using a chemiluminescent enzyme immunoassay (CLEIA) was introduced in 2008. However, there is no consensus on the minimal infectious dose of PVB19 permissible for red blood cells (RBCs). CASE REPORT: A 64-year-old man, who had received hemodialysis for diabetic nephropathy for 5 years, underwent an RBC transfusion for anemia caused by hemorrhagic enterocolitis...

BACKGROUND: The serum levels of galactose-deficient immunoglobulin (Ig)A1 (Gd-IgA1) represent the most promising candidate biomarker for IgA nephropathy (IgAN). The aim of this study was to evaluate the serum levels of Gd-IgA1 as a novel noninvasive biomarker for post-transplant IgAN recurrence. METHODS: Serum Gd-IgA1 levels of 18 patients with recurrent IgAN were compared with control renal transplant recipients (n = 23) with non-recurrent IgAN and control non-transplant IgAN patients (n = 44) and healthy relatives (n = 11)...

Monoclonal gammopathy of renal significance (MGRS) can manifest in many different ways depending on the nature of the immunoglobulin and its physicochemical properties. MGRS can lead to the discovery of a hematological malignancy. We report the case of a 32-year-old female patient who underwent renal biopsy on account of an impure nephrotic syndrome associated with immunoglobulin (Ig)G κ monoclonal gammopathy. Histological analysis revealed membranoproliferative glomerulonephritis with IgG, IgM, κ, λ, and C3 deposits...

Immunoglobulin (Ig) A nephropathy is one of the most common primary glomerulonephritides worldwide causing end stage renal disease in up to 20-40% of affected patients, nearly two decades post diagnosis. Kidney transplantation is the treatment of choice for patients with renal failure, secondary to glomerular diseases. However, IgA nephropathy has a strong tendency to recur in the graft, and although initially thought to be a benign condition, several reports of graft loss, due to recurrent IgA nephropathy, there have been over the last three decades...

Background: One of the most significant clinical trials, demonstrating the efficacy of tonsillectomy (TE) for recurrent throat infection in severely affected children, was published in 1984. This systematic review was undertaken to compile various indications for TE as suggested in the literature after 1984 and to stratify the papers according to the current concept of evidence-based medicine. Material and methods: A systematic Medline research was performed using the key word of "tonsillectomy" in combination with different filters such as "systematic reviews", "meta-analysis", "English", "German", and "from 1984/01/01 to 2015/05/31"...

Immunoglobulin (Ig)A nephropathy is the most prevalent primary chronic glomerular disease in the world. Studies of molecular and cellular interactions involved in the pathogenesis of IgA nephropathy have revealed several inherent abnormalities in the production and subsequent handling of IgA1. In patients with this disease, altered glycan structures in the unique hinge region of the heavy chains of IgA1 molecules lead to the exposure of antigenic determinants, which are recognized by naturally occurring antiglycan antibodies of the IgG and/or IgA1 isotype...

The identification of risk factors conditioning the progression of immunoglobulin (Ig)A nephropathy (IgAN) is needed due to the variability of the outcome of this renal disease, which ranges from remission or indolent course to progressive slow loss of renal function or rapidly evolving chronic renal failure. Based on the supposed individual risk of progression, the therapy is modulated from renin-angiotensin inhibitors to corticosteroids, alone or associated with other powerful but potentially harmful immunosuppressors...

Streptococcus mutans is a major pathogen of human dental caries. Strains harbouring the cnm gene, which encodes Cnm, a collagen-binding protein, contribute to the development of several systemic diseases. In this study, we analysed S. mutans strains isolated from the oral cavity of immunoglobulin (Ig)A nephropathy (IgAN) patients to determine potential relationships between cnm and caries status as well as IgAN conditions. Saliva specimens were collected from 109 IgAN patients and the cnm status of isolated S...

Disorders of plasma and B cells leading to paraproteinemias are associated with a variety of renal diseases. Understanding the mechanisms of injury and associated nephropathies provides a framework that aids clinicians in prompt diagnosis and appropriate adjunctive treatment of these disorders. Glomerular diseases that may be associated with paraproteinemias include amyloid deposition, monoclonal Ig deposition disease, proliferative GN with monoclonal Ig deposits, C3 glomerulopathy caused by alterations in the complement pathway, immunotactoid glomerulopathy, fibrillary GN, and cryoglobulinemia...

The incidence of glomerulonephritis, as a manifestation of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), has always been considered low. Though renal infiltration is usually detected at post-mortem, it does not often interfere with kidney function [1]. Though immunoglobulin (Ig) levels in most CLL patients are subnormal, small monoclonal Ig peaks are occasionally detected in serum. They were present in a number of reported CLL nephropathy patients, and not all were cryoglobulins; serum and glomerular staining were concordant for Ig type [2,3,4]...

Methicillin-resistant Staphylococcus aureus (MRSA) is an emerging pathogen that infects the skin and soft tissue. However, there are few reports of renal complications from MRSA involving immunoglobulin (Ig)A-dominated rapidly progressive glomerulonephritis (GN). Favorable renal outcomes from IgA GN are achieved by administering timely therapy. In the present study, we describe the case of a healthy young woman suffering from a cutaneous MRSA infection that initially presented with gross hematuria. Six months after eradicating the infection, severe impairment of renal function was noted because of intractable nausea and vomiting...

Although kidney disease is much less common in children than in adults, clinicians must remain alert for the renal conditions that occur in this population because prompt diagnosis and management are essential. Acute postinfectious glomerulonephritis occurs as an uncommon sequela of streptococcal and other infections. Management is focused on providing supportive measures, including management of fluid-electrolyte imbalance and hypertension, until the patient recovers. Immunoglobulin (Ig) A nephropathy is a primary glomerulonephritis related to abnormal IgA glycosylation...
