1. PR3-ANCA-positive crescentic necrotizing glomerulonephritis accompanied by isolated pulmonic valve infective endocarditis, with reference to previous reports of renal pathology.
Match Strength: 4.833
Patients with infective endocarditis (IE) often have renal complications which may include infarcts, abscesses and glomerulonephritis (GN). Furthermore, it is generally accepted that there is an association between IE and anti-neutrophil cytoplasmic antibody (ANCA). Here, we report the case of a 24-year-old man who developed rapidly progressive GN in the course of IE due to infection with alpha-streptococcus. The initial clinical manifestation of the condition was severe sacroiliitis without fever. Sandwich ELISA showed that the patient was positive for PR3-ANCA at low titer, and the classical ...

2. A nephritogenic peptide induces intermolecular epitope spreading on collagen IV in experimental autoimmune glomerulonephritis.
Match Strength: 4.478
This group previously identified a peptide p13 of alpha3(IV)NC1 domain of type IV collagen that induces experimental autoimmune glomerulonephritis (EAG) in rats with generation of antibodies to sites on alpha3(IV)NC1 external to the peptide as a result of intramolecular epitope spreading. It was hypothesized that intermolecular epitope spreading to other collagen IV chains also was induced. Rats were immunized with nephritogenic peptide that was derived from the amino terminal part of rat alpha3(IV)NC1 domain, and serum and kidney eluate were examined for antibodies to both native and ...

3. Microscopic polyangiitis associated with primary biliary cirrhosis: a causal or casual association?
Match Strength: 4.176
The association between microscopic polyangiitis (MPA) and primary biliary cirrhosis (PBC) has seldom been reported. We describe a patient with PBC and MPA who presented with polyarthritis and pulmonary nodules followed by pauci-immune crescentic glomerulonephritis and liver dysfunction. Detection of p-ANCA, antimyeloperoxidase, and antimitochondrial antibodies along with liver and renal histopathology allowed a diagnosis of MPA and PBC. We also discuss 2 other cases that could be unrecognized associations of both diseases. Further reports are necessary to clarify if the coexistence between ... Read More »

4. Differential capacity of anti-RAP and anti-megalin antibodies to produce progressive passive Heymann nephritis - implications for the pathogenesis of idiopathic human membranous glomerulonephritis.
Match Strength: 4.139
Passive Heymann nephritis (PHN) induced with heterologous antisera has been described according to various criteria, which may or may not include induction of chronic disease and proteinuria. Characteristics of the glomerular immune deposits determined by the antigenic specificities of the antisera presumably account for differences in disease outcome. In this study, the clinical and immunohistological features in the model produced with monospecific antisera were compared against megalin or receptor associated protein (RAP), two proteins that have been implicated as target antigens in PHN. ...

5. Rituximab therapy for mixed cryoglobulinemia in seven renal transplant patients.
Match Strength: 2.870
Systemic B-cell depletion and clinical remission of the systemic effects of cryoglobulins have been achieved in hepatitis C virus-positive immunocompetent patients with rituximab, a human/mouse chimeric monoclonal antibody that specifically reacts with the CD20 antigen. Thus, this provides a rationale for the use of rituximab for type III cryoglobulin-related graft dysfunction in renal-transplant patients. Seven patients, of whom five were hepatitis C positive, developed renal function impairment long after transplantation, as well as de novo nephrotic syndrome (n = 5), severe hypertension (n ...

6. Life-threatening cryoglobulinemia: clinical and immunological characterization of 29 cases.
Match Strength: 2.725
OBJECTIVES: To analyze the etiology, clinical presentation, and outcomes of patients with life-threatening cryoglobulinemic vasculitis. METHODS: We studied 209 consecutive patients with cryoglobulinemic vasculitis. A potentially life-threatening cryoglobulinemia was considered as the development of renal failure, vasculitic abdominal involvement, pulmonary hemorrhage, or central nervous system involvement. RESULTS: Twenty-nine (14%) patients had life-threatening cryoglobulinemic vasculitis. There were 17 women and 12 men, with a mean age of 57 years. In 17 (59%) patients, life-threatening ...

7. Impact on peritoneal membrane of use of icodextrin-based dialysis solution in peritoneal dialysis patients.
Match Strength: 2.508
The usefulness of icodextrin-containing peritoneal dialysis (PD) solution for the management of body fluid and blood pressure has been reported. However, icodextrin PD solution is a foreign solution in the body, and the possible induction of intraperitoneal inflammation has been reported. In this study, we investigated at 6-month intervals the influence of icodextrin solution on peritoneal permeability and inflammatory reactions in patients in whom glucose solution had been changed to icodextrin solution for the overnight dwell. We enrolled 9 anuric PD patients (5 men, 4 women) of mean age 58 ... Read More »
