A 47-year-old woman developed pulmonary hemorrhage and an increase in proteinuria during remission of membranous nephropathy. Renal biopsy revealed crescentic glomerulonephritis. She also had a high perinuclear antineutrophil cytoplasmic antibody level, so a diagnosis of myeloperoxidase-antineutrophil cytoplasmic antibody-associated glomerulonephritis was made. After immunosuppressive therapy w...

A 56 year old man presented with thrombophlebitis, nephrotic range proteinuria and multiple pulmonary nodules. A renal biopsy showed membranous glomerulonephritis, and after a thoracotomy a diagnosis of sarcoidosis was established. A pulmonary nodular pattern is unusual in sarcoidosis and is often mistaken for malignant disease. The association of this type of pulmonary involvement and membrano...

BACKGROUND Despite the development of biomarkers and noninvasive imaging tools, biopsy remains the only method for correctly diagnosing patients with unexplained hematuria, proteinuria and renal failure. Renal biopsy has been performed for several decades in Taiwan; however, a national data registry is still lacking until 2013. METHODS The Renal Biopsy Registry Committee was established withi...

The incidence of persistent hepatitis B surface (H13s) antigenaemia was studied in 114 nephrotic children with glomerulonephritis. Twenty five (24 boys) of 28 cases of membranous glomerulonephritis were HBs antigen (HBsAg) carriers. Only 9 of the remaining 86 patients with nephropathies other than membranous glomerulonephritis were HBsAg positive. H:BsAg immune complexes were seen in the sera b...

BACKGROUND IgG4-related disease is a recently described pathologic entity. This is the case of a patient with nephrotic syndrome and lymphadenopathy due to IgG4-related disease. Such a kidney involvement is quite peculiar and has only been described a few times recently. Renal biopsy showed a glomerular involvement with membranous glomerulonephritis in association with a tubulo-interstitial nep...

Inflammatory bowel diseases (IBD) are two different types of chronic noninfectious gastrointestinal inflammatory diseases, namely Crohn’s disease and Ulcerative colitis. Renal involvement exists among the extraintestinal involvements IBD. IBD renal in form glomerulonephritis, tubulointerstitial nephritis, nephrolithiasis, amyloidosis. In this article, a 79-year-old male patient who presented wi...

After renal transplantation approximately forty percent of patients with membranous glomerolunephritis (MGN) had a recurrence, most commonly during the first year.We present two cases with recurrent MGN after kidney transplantation who successfully treated with ritoximab.
