moderate and severe activity in terms of grade, portal inflammatory activity, interface, and portal hepatitis in DIAH versus AIH, no significant differences were found (data not shown). A total of six patients with DIAIH had a follow-up liver biopsy, and all had either very mild or no inflammatory activity www.selleckchem.com/products/idasanutlin-rg-7388.html in the follow-up biopsy. Comparison between the histological features in the nitrofurantoin-induced and minocycline-induced AIH patients showed similar grade and stage in these patients (Table 4). In general the necroinflammatory activity was found to be higher in the nitrofurantoin-induced AIH than in the AIH induced by minocycline (Table 4). Changes on radiological images were evident in 8 of 11 (73%) of the nitrofurantoin-induced AIH cases, whereas this was not observed in any of the minocycline patients (P = 0.0010). Furthermore, other AIH patients had abnormalities on imaging in only 24% (8/33) of cases versus 73% of the nitrofurantoin patients (P = 0.0089). In most of the AIH patients with abnormalities on imaging, the liver showed mild atrophy (n = 4), clear signs of cirrhosis (atrophy and signs of portal hypertension such as ascites)

(n = 2), or coarsening of the liver architecture “compatible” with chronic liver disease (n = 2). In several nitrofurantoin patients, the appearance of the liver was considered this website “cirrhotic” on imaging but cirrhosis was not shown to be present histologically in any of the nitrofurantoin (or the minocycline) patients. Two patients had left lobe liver atrophy, two patients had right lobe liver atrophy, and two patients had diffuse general liver atrophy. In five patients, computed tomography or magnetic resonance imaging showed confluent area of abnormality with distortion of surrounding liver parenchyma (Figs. 1-3). The confluent abnormal area showed retention of contrast on delayed-phase images, consistent with confluent fibrosis or massive Selleck Tenofovir fibrotic bands. In some cases when images were obtained at presentation, the confluent area showed fairly intense enhancement

during the portal phase of enhancement. This early enhancement is somewhat unusual for typical confluent fibrosis, but may have been due to active or subacute phase of the disease. The appearance of confluent fibrosis or massive fibrotic bands (Figs. 1-3) was only seen in the nitrofurantoin patients and in none of the AIH patients. One of the patients with right liver atrophy also had a large mass in the right lobe and hypertrophy of the left liver lobe. Another patient had heterogeneous echotexture, with a subtle 3-cm mass in the right lobe that on the original imaging was similar to focal nodular hyperplasia but was clinically considered secondary to the nitrofurantoin-induced liver damage, and the patient was in clinical and biochemical remission at follow-up.
