TGFβ signaling plays a central role in the development of acute and chronic kidney diseases. Previous in vivo studies involved systemic alteration of TGFβ signaling, however, limiting conclusions about the direct role of TGFβ in tubular cell injury. Here, we generated a double transgenic mouse that inducibly expresses a ligand-independent constitutively active TGFβ receptor type 1 (TβR1) kinase...

Tenofovir disoproxil fumarate (TDF) is effective against chronic hepatitis B (CHB) infection and its use is increasing rapidly worldwide. However, it has been established that TDF is associated with renal toxicity in human immunodeficiency virus-infected patients, while severe or symptomatic TDF-associated nephrotoxicity has rarely been reported in patients with CHB. Here we present two patient...

Plasma renin concentration (PRC) was measured in 25 rabbits before and 6, 24, or 72 hours after subcutaneous injection of glycerol. Renal failure and tubular necrosis developed in most animals and PRC rose sixfold to a maximum at 24 hours. Small insignificant changes of PRC were present at 6 and 72 hours. None of these changes was observed in a control group of nine animals killed 24 hours afte...

PURPOSE Prophylactic antibiotics have been used in acute necrotizing pancreatitis with mixed results. This meta-analysis analyzes the effects of prophylactic antibiotics in necrotizing pancreatitis. METHODS Multiple databases and abstracts were searched for randomized trials comparing treatment with prophylactic antibiotics to treatment without prophylactic antibiotics in necrotizing pancreat...

Immunoglobulin A (IgA) nephropathy associated with cirrhosis is the most common form of secondary IgA nephropathy (IgAN). Cirrhosis-related IgAN is usually clinically silent with a rare occurrence of gross hematuria, unlike in cases of idiopathic IgAN. Especially, acute tubular necrosis (ATN) associated with gross hematuria is very rare in cirrhosis-related IgAN, although acute renal failure is...

Acute tubular necrosis (ATN) is a syndrome of intrinsic renal failure secondary to ischemic or toxic insults. The histopathologic findings of ATN are inconstant. When present, they are limited to the tubulo-interstitium and often subtle despite profound dysfunction. Experimental models of ATN in healthy animals commonly use single insults that result in extensive injury, circumstances that do n...

Renal allograft rupture (RAR) is a rare but lethal complication of renal transplantation. It potentially threatens graft and patient survival. RAR is frequently associated with acute rejection, but other causes like renal vein thrombosis and acute tubular necrosis have also been observed. Most commonly a graft nephrectomy is required, but graft repair can also be attempted in selected cases to ...
