The effect of bilirubin on biliary lipid secretion: Analysis by horseradish peroxidase associated intrahepatic vesicular transport system

The mechanism of biliary lipid secretion is still controverial and there is no definite information regarding how bilirubin inhibits biliary phospholipid and cholesterol secretions without affecting bile salt secretion. In this study, the effects of biliribin on intrahepatic vesicular transport and biliary lipid secretion were examined using bile-fistula rats. Horseradish peroxidase (HRP) was used as a tracer of intrahepatic vesicular transport. Bilirubin (5mg/100g BW) and/or HRP (5mg/100gBW) were injected through the mesenteric vein. Bile flow, biliary bile acid, biliary phospholipid and cholesterol outputs were examined in saline, HRP and HRP+bilirubin groups, respectively. Bile flow and biliary bile acid output were not affected by bilirubin administration. Biliary phospholipid and cholesterol as well as biliary HRP outputs were inhibited just after bilirubin administration, 42.8±6.1 SD% 47.7±5.1 SD%, and 33.4±3.8 SD%, respectively. These results suggested the participation of intrahepatic vesicular transport system in the inhibition of biliary lipid secretion by bilirubin and in its secretory mechanism. This study was partially funded by Uehara Life Science Foundation.     

Gallbladder bile composition in patients with Crohn＇s disease

AIM:To further elucidate the pathogenesis andmechanisms of the high risk of gallstone formation inCrohn's disease.METHODS:Gallbladder bile was obtained from patientswith Crohn's disease who were admitted for electivesurgery (17 with ileal/ileocolonic disease and 7 withCrohn's colitis).Fourteen gallstone patients servedas controls.Duodenal bile was obtained from tenhealthy subjects before and after the treatment withursodeoxycholic acid.Bile was analyzed for biliary lipids,bile acids,bilirubin,crystals,and crystal detection time(CDT).Cholesterol saturation index was calculated.RESULTS:The biliary concentration of bilirubin wasabout 50% higher in patients with Crohn's disease thanin patients with cholesterol gallstones.Ten of the patientswith Crohn's disease involving ileum and three of thosewith Crohn's colitis had cholesterol saturated bile.Fourpatients with ileal disease and one of those with colonicdisease displayed cholesterol crystals in their bile.About1/3 of the patients with Crohn's disease had a shortCDT.Treatment of healthy subjects with ursodeoxycholicacid did not increase the concentration of bilirubin induodenal bile.Several patients with Crohn's disease,with or without ileal resection/disease had gallbladderbile supersaturated with cholesterol and short CDT andcontained cholesterol crystals.The biliary concentrationof bilirubin was also increased in patients with Crohn'scolitis probably not due to bile acid malabsorption.CONCLUSION:Several factors may be of importance forthe high risk of developing gallstones of both cholesteroland pigment types in patients with Crohn's disease.     

Cholestatic Effect of Large Bilirubin Loads and Cholestasis Protection Conferred by Cholic Acid Co-infusion: a Molecular and Ultrastructural Study

Background: Large intravenous bilirubin loads block biliary phospholipid secretion, produce canalicular membrane lesions and cause canalicular cholestasis. Cholic acid co-infusion forestalls these untoward effects. The aim of this study was first to determine whether bilirubin overload causes cholestasis through reducing the activity or the hepatic expression of the bile salt export pump ( bsep ) or Na-taurocholate cotransporting polypeptide ( ntcp ) and, secondly, whether cholic acid co-infusion forestalls cholestasis by upregulating bsep, ntcp or phosphoglycoprotein 3 ( pgp3 ) expressions or activities. A further aim was to determine whether large bilirubin infusions also produce ultrastructural changes inside hepatocytes. Methods: The effects of intravenous infusion of 2 g bilirubin over 150 min on hepatic expression of bsep, ntcp and pgp3 were studied in bile acid-depleted and cholic acid co-infused pigs, and related to canalicular bile acid transport and bile secretion. Effects on hepatocyte ultrastructural morphology were analysed by electron microscopy. Results: Bilirubin-induced cholestasis reflected marked diminution of bsep and pgp3 transport activities and not reduced hepatic expression of these transporters. Hepatocyte ultrastructural abnormalities were predominantly confined to the hepatocyte canalicular membrane in cholestatic livers. Cholic acid co-infusion with bilirubin conferred complete cholestasis protection through enhancing pgp3 and bsep transporter activities and not through upregulating their expression. Bilirubin infusion did not change ntcp expression. Conclusion: Bilirubin-induced cholestasis is due to markedly impaired activity of the membrane-embedded bsep transporter consequent upon ultrastructural injury to the canalicular membrane. Cholic acid co-infusion with bilirubin enhances bsep and pgp3 activities and confers protection against canalicular membrane injury and bilirubin-induced cholestasis.     

吸烟对血清总胆红素浓度的影响及其在致冠心病中的作用

目的：探讨吸烟对血清总胆红素浓度的影响及其在致冠心病（ Ｃ Ｈ Ｄ）中的作用。方法：对符合条件的１４８例患者作选择性冠状动脉造影检查,同时调查其吸烟史,分成吸烟组（５４例）、戒烟组（２８例）及非吸烟组（６６例）。采清晨空腹静脉血测定血清总胆红素浓度并进行比较。结果：吸烟组血清总胆红素浓度显著低于戒烟组（ Ｐ ＜ ０．０５）及非吸烟组（ Ｐ ＜ ０．０１）,而戒烟组与非吸烟组间血清总胆红素浓度无显著性差异。血清总胆红素浓度与 Ｃ Ｈ Ｄ 发病率间有明显负相关（ Ｐ ＜ ０．０１）。血清胆红素水平越低者,患 Ｃ Ｈ Ｄ 的相对危险度越高。结论：吸烟显著降低血清总胆红素浓度并可能以此作为其增加 Ｃ Ｈ Ｄ 危险性的途径之一。     

Association of serum bilirubin levels with development and progression of albuminuria,and decline in estimated glomerular filtration rate in patients with type 2 diabetes mellitus

Aims/Introduction

Recent observational studies suggest elevated levels of bilirubin, an endogenous anti‐oxidant, might protect against kidney disease. We carried out an observational cohort study to assess whether higher baseline levels of bilirubin, within normal range, could predict the rate of development and progression of diabetic nephropathy in patients with type 2 diabetes.

Materials and Methods

Japanese type 2 diabetic patients with normo‐ or microalbuminuria and normal serum bilirubin (<1.2 mg/dL) were recruited from a single center, and categorized according to baseline serum bilirubin levels. Two independent end‐points were specified: development or progression of diabetic nephropathy, based on transition to a more advanced stage of albuminuria (albuminuria cohort), and the rate of change in estimated glomerular filtration rate (eGFR cohort).

Results

Albuminuria and eGFR cohorts were constructed consisting of 1,915 patients and 1,898 patients, respectively, with 1,738 patients overlapping. Mean follow up was 4.4 and 5.4 years for the two cohorts, respectively. Within the albuminuria cohort, 132 (9%) of 1,418 patients with normoalbuminuria developed microalbuminuria, and 56 (11%) of 497 patients with microalbuminuria developed macroalbuminuria. Higher baseline bilirubin levels were associated with significantly lower risk of progression from microalbuminuria to macroalbuminuria in both the univariate and multivariate analyses. In normoalbuminuric patients, an inverse association was found when restricted to a subgroup with elevated hemoglobin A1c levels. There was no relationship between bilirubin levels and the rate of change in eGFR.

Conclusions

Higher serum bilirubin levels, within normal range, might be predictive of a lower risk of progression of nephropathy in type 2 diabetic patients.

Association between serum bilirubin and cardiovascular disease in an overweight high risk population from the SCOUT trial

Background and aimsAn inverse relationship between (serum) total bilirubin and risk of cardiovascular disease has been reported previously, but longitudinal data on overweight and obese patients are lacking. We have investigated the relationship between total bilirubin and cardiovascular adverse events in a large group of patients with risk factors for cardiovascular disease who were enrolled in a large weight loss trial.Methods and resultsData from the Sibutramine Cardiovascular Outcomes (SCOUT) trial, including almost 10.000 overweight/obese high cardiovascular risk patients, were used. The relationship between total bilirubin level at screening and the primary outcome (i.e. non-fatal myocardial infarction, non-fatal stroke, resuscitated cardiac arrest or cardiovascular death) for the entire study period was investigated using Cox proportional hazards models. The population was divided into four groups based on total bilirubin levels (normal range 5–25 μmol/L). Time-dependent Cox analyses were also performed to adjust for weight loss over time. Initial analyses adjusted for sex, age and treatment allocation showed significantly reduced hazard ratios of 0.80 (95% confidence interval 0.68–0.94), 0.73 (0.62–0.86) and 0.77 (0.65–0.91), for the three higher total bilirubin groups: >8 and ≤10 μmol/L, >10 and ≤13 μmol/L and >13 μmol/L (5–95 interpercentile range for total bilirubin at screening; 6–19 μmol/L), compared to the lowest total bilirubin group ≤8 μmol/L. When adjusting for classical cardiovascular risk factors, estimates increased towards unity. Additional adjustment for indicators of liver function did not alter the results. A time-dependent Cox model, adjusted for weight loss, demonstrated a similar trend.ConclusionBilirubin was not a risk-factor independent from other traditional cardiovascular risk-factors in our population.
