We report a case with immunoglobulin A (IgA) nephropathy, showing IgA deposition which disappeared after peripheral blood stem cell transplantation (PBSCT) for acute lymphocytic leukemia (ALL). In 1996, a 28-year-old man was diagnosed with IgA nephropathy by renal biopsy. Steroid therapy improved proteinuria from 3 g/day to 1 g/day. In 2003, he received PBSCT following the initial therapy for A...

PolTmeric IgA in sera was determined by thin-layer gel filtration in patients with IgA ncphropathy, other glomerular diseases, IgA myeloma and healthy adults to determine whethcr serum IgA is composed of a monomcric and/or larger pelymers in these patients. The levels of IgA in sera were also quantitated by laser nephelometer in these patients. Eleven patients with IgA nephropathy (Berger's dis...

  Abstract   Pseudoxanthoma elasticum is a rare, hereditary, multisystemic disease affecting   the skin, eye, and cardiovascular system. Renal involvement is uncommon.   We describe two cases of pseudoxanthoma elasticum (PXE) in two women with   distinctive skin lesions and nephrocalcinosis that renal ultrasonography showed a   characteristic pattern of dotted increased echogenicity in the cort...

Chronic kidney disease (CKD) is a worldwide public health problem that affects millions of people from all racial and ethnic groups. Although CKD is not one specific disease, it is a comprehensive syndrome that includes IgA nephropathy. As reported by the Japanese Society of Nephrology, 13.0 million people have CKD. In Japan, major causes of end-stage kidney disease are type 2 diabetic nephropa...

Introduction IgA nephropathy is a chronic renal disease characterized by mesangial immunodeposits that contain autoantigen, which is aberrantly glycosylated IgA1 with some hinge-region O-glycans deficient in galactose. Macroscopic hematuria during an upper respiratory tract infection is common among patients with IgA nephropathy, which suggests a connection between inflammation and disease acti...

Two patients (one male, one female) with ankylosing spondylitis (AS) and IgA nephropathy are described. The female patient is the first reported case to have AS and IgA nephropathy concurrently. Contrary to previously reported cases, her renal manifestation preceded her rheumatic symptoms. It is suggested that women with IgA nephropathy and AS may be overlooked as the severity of spondylitis an...

Urethral amyloidosis is a rare condition that can cause hematuria and urinary obstruction symptoms. While there is no established association between immunoglobulin A (IgA) nephropathy and secondary amyloidosis, which is typically found in chronic inflammatory conditions, it is hypothesized that IgA nephropathy may be a systemic condition with inflammatory mediators. We present a case of urethr...

Diseases associated with immunoglobulin A (IgA) antibody include linear IgA dermatosis, IgA nephropathy, Celiac disease, Henoch-Schönlein purpura, etc. Although usually idiopathic, IgA antibody is occasionally induced by drugs (e.g., vancomycin, carbamazepine, ceftriaxone, and cyclosporine), malignancies, infections, and other causes. So far, only a few cases of IgA bullous dermatosis coexistin...

Renal involvement in multiple myeloma (MM), which accounts for about 10% of all haematological malignancies, is not uncommon. Immunoglobulin A (IgA) nephropathy and IgA lambda myeloma with mesangial proliferative glomerulonephritis (GN) have been reported [1]. An interaction between mesangial cells and IgA as well as IgG immune complexes provides a possible mechanism for glomerular injury in Ig...

BACKGROUND Glomerular deposition of IgA1 is a common feature of Henoch-Schönlein purpura, and is indistinguishable from that seen in IgA nephropathy. Serum IgA1 is abnormally O-glycosylated in IgA nephropathy, and this may contribute to mesangial IgA1 deposition and the development of glomerular injury. This altered O-glycosylation of IgA1 can be detected by its increased binding to the lectin ...
