IgA nephropathy associated with seronegative spondylarthropathies

Silicosis associated with crescentic IgA mesangial nephropathy.

Patients with IgA Nephropathy

The actual state of IgA nephropathy in Japan was surveyed throughout the nation by a questionnaire. Five hundred patients were collected from 26 departments of pediatrics and 2,1 75 from 27 internal medicine. IgA nephropathy accounted for 19.2% of the children and 30.0% of the adults among primary glomerular diseases. Most of the patients, regardless children and adults, were detected by chance...

Systemic Sarcoidosis Associated to IgA Nephropathy

The sarcoidosis was rarely associated to IgA nephropathy. We report a 38-year-old man presented decreased visual acuity and xerostomia. He had two axillary lymphadenopathies and pitting edema of legs in physical examination. The ophthalmological examination revealed a right posterior uveitis. Biological investigations showed a mild renal insufficiency and elevated serum level of angiotensin-con...

Staphylococcus infection-associated glomerulonephritis mimicking IgA nephropathy.

The association of methicillin-resistant Staphylococcus aureus (MRSA) infection with glomerulonephritis (GN) has been well documented in Japan but not in North America. Recently, eight renal biopsies with IgA-predominant or -codominant GN from eight patients with underlying staphylococcal infection, but without endocarditis, were observed at a single institution in a 12-mo period. Renal biopsie...

Early Diagnosis of Tuberculosis-Associated IgA Nephropathy with ESAT-6.

IgA nephropathy (IgAN) is the most common cause of primary renal diseases worldwide, and the early secreted antigenic target of 6 (ESAT-6) which was secreted by Mycobacterium tuberculosis (MTB) may be involved in the development and progression of IgAN. This study aimed to investigate the role of ESAT-6 for early diagnosis of IgAN caused by MTB infection. From 2011 to 2014, 21 patients with ren...
