Membranous Glomerulopathy Subtyping

The diagnosis of membranous glomerulopathy has evolved rapidly in the past 10 years since the identification of PLA2R as the major target antigen in primary membranous glomerulopathy. Today, rather than subtyping into vague categories such as 'primary' and 'secondary', we have tools available to name the specific type of disease present in most cases. Arkana Laboratories offers diagnostic testing for membranous glomerulopathy including immunohistochemical stains for tissue typing of PLA2R, THSD7A, EXT1/2, and NELL1 membranous and serum testing to monitor disease in patients with PLA2R and THSD7A-associated membranous glomerulopathy.

Endocarditis-Associated Glomerulonephritis

The patient is a 45-year-old IV drug user who presents with fevers, chills, hematuria, and fatigue. On laboratory testing, he was found to have a creatinine of 4.8. Complement levels are depressed and blood cultures are positive. A transesophageal echocardiogram confirmed the presence of endocarditis. A kidney biopsy was obtained due to hematuria. Image 1 and Image 3 shows circumferential cellular crescents with fibrinoid necrosis (many intracapillary neutrophils are seen in image 3). Figure 2 shows severe interstitial fibrosis. Images 4 and 5 show immunofluorescence staining with IgM and C3, respectively. This is a case of endocarditis-associated glomerulonephritis with diffuse...

River the Office Dummy

Last week Gail pulled her dummy from the closet (he goes by River around here) to set him up as someone taking a nap in the common space. Since then, River has entertained a visitor... Caught up on some reading... And started to plan his Halloween costume!  He's really been checking things off of his to-do list this past week.
