363). Duration of treatment until enzyme normalization and duration of AZA therapy were significantly associated with AZA toxicity (
= 0.007 and
= 0.01, respectively). At the first follow-up treatment with AZA, total leucocyte count (TLC) and neutrophil counts were significantly lower in group 1 (
= 0.005 and
= 0.002, respectively). Moreover, the percentage reduction of TLC and neutrophil counts were significantly higher in group 1 (
< 0.001, for both).
Monitoring for AZA adverse events in those with the defined predictors of AZA-related adverse events is more important than TPMT assessment.

To assess ductular proliferation (DP) and ductal plate malformation (DPM) in biliary atresia (BA) by means of immunohistochemical staining using cytokeratins CK7 and CK19 and neural cell adhesion molecule (NCAM) antibody CD56.
In 10 cases of BA, liver surgical biopsies obtained at the time of hepatoportoenterostomy were stained with H&E, PAS, Gomori and Azan methods. Immunohistochemical technique was used to outline bile ducts, ductular reaction, reactive bile duct/ductules and DPM by CK7, CK19 and NCAM antibody CD56.
We found fibrosis, bile stasis and mild inflammation in all cases. In the routine staining DP was not seen in 3 cases. The immunohistochemical staining by means of CK19 was helpful in the detection of DP, and allowed it to be demonstrated in all cases. The biliary epithelial cell markers for CD56, CK7, CK19 were used for demonstration of bile duct cell but not hepatocyte alterations in the structure of intrahepatic biliary ducts and different stages of maturation. CD56 as a marker of immature bile ducts was expressed on biliary epithelium of bile ducts and bizarre forms of DPM in 6 cases. selleck products The positive expression of CD56 corresponded to the co-localization of CK19 of DPM, but not CK7, to the ductular reaction at the limiting plate of portal tracts. CD7, considered as a marker of DP, also stained ductal hepatocytes and multipotential oval cells, and was a marker of DPM in 3 cases.
Use of CK7, CK19 and CD56 is helpful in BA diagnosis and allows differentiation of the stage of developing bile duct cells according to the expression pattern.

Cholestasis is a serious complication affecting other organs such as the liver and kidney. Oxidative stress and mitochondrial impairment are proposed as the primary mechanisms for cholestasis-induced organ injury. Taurine (TAU) is the most abundant free amino acid in the human body, which is not incorporated in the structure of proteins. Several pharmacological effects have been attributed to TAU. It has been reported that TAU effectively mitigated oxidative stress and modulated mitochondrial function. The current study aimed to evaluate the impact of TAU on oxidative stress biomarkers and mitochondrial parameters in the kidney of cholestatic animals.
Bile duct ligated (BDL) rats were used as an antioxidant model of cholestasis. Animals were treated with TAU (500 and 1000 mg/kg, oral) for seven consecutive days. Animals were anesthetized (thiopental 80 mg/kg, i.p.), and kidney and blood specimens were collected.
Severe elevation in serum and urine biomarkers of renal injury was evident in the BDL group. Significant lipid peroxidation, reactive oxygen species (ROS) formation, and protein carbonylation were detected in the kidney of BDL animals. Furthermore, depleted glutathione reservoirs and a significant decrease in the antioxidant capacity of renal tissue were detected in cholestatic rats. Renal tubular atrophy and interstitial inflammation were evident in BDL animals. Cholestasis also caused significant mitochondrial dysfunction in the kidney. TAU significantly prevented cholestasis-induced renal injury by inhibiting oxidative stress and mitochondrial impairment.
These data indicate TAU as a potential therapeutic agent in the management of cholestasis-induced renal injury.

The primary purpose of this study was to assess the association of obstructive sleep apnea (OSA) and non-alcoholic steatohepatitis (NASH) from a large national inpatient sample database.
We conducted a retrospective analysis using the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample. OSA and NASH patients were identified using the ICD-10-CM code G47.33 and K75.81. Non-NASH patients (control) were randomly selected and matched by age and gender to each NASH patient in a 4 1 ratio. Weighted logistic regression models were used to calculate the association between OSA and NASH in addition to different comorbidities.
A total of 54,169 participants were included in our analysis; 10,740 cases of NASH were matched to 43,429 controls (non-NASH). NASH was significantly higher in the white population (82.12% vs. 76.64%,
< 0.001). The prevalence of OSA among NASH patients was significantly higher compared to the control group (15.8% vs. 8.9%, adjusted OR 1.34, 95% CI 1.14-1.56,
= 0.0003). The prevalence of celiac disease and Crohn's disease was significantly higher in patients with NASH (0.7% vs. 0.2%,
< 0.0002 and 1.28% vs. 0.76%,
< 0.0001). Multiple comorbidities were significantly elevated in the NASH group compared to the non-NASH group, including diabetes mellitus (DM; 36% vs. 17.6%,
< 0.0001), obesity (36.4% vs. 18.2%,
< 0.0001) and metabolic syndrome (0.86% vs. 0.06%,
< 0.0001). The mortality rate was significantly higher in the NASH group (3.8% vs. 2%,
< 0.0001).
This is the first study using the ICD-10-CM code with a specific search code for NASH. Our large population database results emphasize that there is a significant association between OSA and NASH.

In ICP PW the first blood sample was drawn at the time of diagnosis, while in HPW it was drawn in the 28th week of pregnancy. The next blood samples were drawn in the 32nd and 36th week of pregnancy and one day after delivery. UDCA was administered when ICP was diagnosed. In ICP PW serum FGF-21 concentration was the lowest at the time of diagnosis with an evident increase after UDCA administration. Serum FGF-21 levels were significantly higher in ICP PW than in HPW from the first to the last measurement. There was a negative association between adiponectin and bile acids (BAs) levels in the later stage of pregnancy in ICP PW. Up-regulated FGF-21 serum levels in ICP patients compared to HPW persisted after delivery, suggesting its role in disease pathophysiology. The negative association between serum adiponectin and BAs of the later stage of pregnancy may suggest its role in regulation of BAs concentration. UDCA exerts a beneficial effect on insulin sensitivity and up-regulates FGF-21 in ICP.
This study aimed to evaluate the outcomes of patients with unresectable gallbladder cancer (GBC) with hilar involvement and cholangitis undergoing percutaneous transhepatic biliary drainage (PTBD).
This retrospective study comprised consecutive patients with unresectable GBC with cholangitis who underwent PTBD. The procedures were categorized as unilateral or bilateral. Bilateral PTBD was classified as simultaneous or sequential. The mean reduction in bilirubin at two weeks was recorded. Complications and mean overall survival were also recorded.
Thirty-three patients (mean age 54.5 years, 12 males) were included. Thirty patients underwent unilateral drainage. Sequential drainage of the contralateral system was performed in 11 patients. Simultaneous bilateral PTBD was performed in 3 patients. PTBD was technically successful in all patients. Mean reduction in bilirubin was 41.5% in the unilateral group. The fall of bilirubin in the simultaneous bilateral PTBD group was 39%. The mean follow-up duration was 36.5 days. No major complications were encountered. At the last follow-up, 7 patients were alive. The mean overall survival was 34.6 days.
Patients with unresectable GBC and cholangitis frequently require bilateral drainage. However, prospective studies should be performed to evaluate whether a sequential or simultaneous PTBD should be performed.

This term includes changes from simple steatosis to steatohepatitis and fibrosis. It was previously thought to be a hepatic manifestation of metabolic syndrome, but recent literature describes this relation as much more complex and bi-directional. Development of NAFLD is associated with other metabolic syndrome components but it can also exacerbate insulin resistance and increase cardiovascular risk. Recently a lot of attention is brought to the role of lipids and lipotoxicity in pathogenesis and progression of non-alcoholic fatty disease. It seems that some lipid classes can be protective against liver injury while others are harmful in excessive amounts. This study presents an overview of the main lipids involved in the pathogenesis of non-alcoholic fatty liver disease and summarizes their association with lipotoxicity, insulin resistance, oxidative stress and other processes responsible for its progression.This research aimed to probe the expression characteristics of poly(A)-binding protein cytoplasmic 1 (PABPC1) and its role on the phenotype of ovarian cancer (OC) cells and to further investigate the possible underlying mechanism. The expression of PABPC1 was analyzed according to the data from gene expression omnibus, The Cancer Genome Atlas (TCGA) and Oncomine databases and the RNA sequencing data set from TCGA were downloaded for evaluating the prognostic values. We revealed that compared with the healthy samples, PABPC1 was upregulated in OC samples. High expression of PABPC1 had a connection with a shorter survival for patients with OC. Loss and gain of function assays revealed that silencing PABPC1 significantly suppressed the viability, invasion and migration of SK-OV-3 cells, while PABPC1 overexpression in A2780 cells showed the reverse outcomes. Moreover, Western blot demonstrated that silencing PABPC1 notably inactivated the epithelial-mesenchymal transition (EMT) process, while upregulation of PABPC1 promoted the mitigation of epithelial phenotype and the acquisition of mesenchymal phenotype.
