Systematic review: The quality of life of patients with biliary atresia

BACKGROUND

The quality of life of patients with Biliary Atresia (BA) have not been systematically examined. The goal of this meta-analysis is to determine patients' postoperative health-related Quality of life (HrQoL) with native or transplanted livers.

METHODS

From 2000 to August 2021, a literature-based search for relevant cohorts was conducted using Pubmed/Medline, the Cochrane Library, and Embase. Original research on BA, Hepatoportoenterostomy (HPE), portoenterostomy, Kasai, Liver transplantation and HrQoL was included. Using RevMan, a forest plot analysis of HrQoL after surgical treatment after BA was calculated (version 5.4). Using MetaXL, a pooled prevalence for cholangitis, secondary liver transplantation, or related malformations was computed (version 5.3).

RESULTS

Nine studies compared individuals with BA to an age-matched healthy control group. 4/9 (n = 352) of these studies found poorer scores for BA patients, while 5/9 (n = 81) found equivalent health status. Factors associated with HrQoL: older age at the time of the survey was linked to greater HrQoL; whereas females, higher total bilirubin and the amount of immunosuppressive medicines were associated with lower HrQoL in BA patients.

CONCLUSION

The current study emphasises the critical need to improve the many parameters influencing HrQoL in BA patients, as well as the methods utilized to assess those factors. This includes immunosuppression, withdrawal from polydrug regimes and recognizing the differences in disease burden between males and females.

Preoperative alkaline phosphatase is a potential predictor of short-term outcome of surgery in infants with biliary atresia

Aim of the study

Biliary atresia (BA) is a fibro-inflammatory cholangiopathy of intra- and extrahepatic biliary radicles. The standard-of-care treatment is surgical restoration of bile flow by Kasai hepatoportoenterostomy (HPE). We aimed to identify the predictors of short-term outcome of the Kasai operation three months postoperatively.

Material and methods

This retrospective study included 107 infants diagnosed with BA by intraoperative cholangiography. All underwent a Kasai operation. The surgical outcome was classified after 3 months post-operatively as successful (bilirubin ≤ 2 mg/dl) or failed (bilirubin > 2 mg/dl). The two groups were compared according to basic clinical, ultrasonographic and histopathological characteristics.

Results

Of the studied patients 29 (27.1%) had a successful outcome while 78 (72.9%) had failed Kasai HPE. Of the preoperative characteristics, lower age and lower serum alkaline phosphatase (ALP) were significantly associated with successful surgical outcome (p = 0.009 and < 0.0001, respectively). In addition, surgical type of BA affected the short-term outcome (p = 0.017), while there was no statistically significant difference regarding the other studied parameters between groups. Age of 69.5 days or less was predictive of successful outcome with 74.4% specificity but with low sensitivity (58.6%), and ALP at a cutoff level of 532.5 U/l or less was predictive of successful outcome with 75.9% sensitivity and 74.4% specificity.

Conclusions

Younger age at the time of surgery and lower ALP are good predictors for the short-term outcome of Kasai HPE with better performance of ALP. This may help to anticipate those who can benefit from surgical correction and those who should be given high priority for transplant referral.

Factors Associated with Timing and Adverse Outcomes in Patients with Biliary Atresia Undergoing Kasai Hepatoportoenterostomy

OBJECTIVE

To assess factors associated with timing of hepatoportoenterostomy (HPE) and adverse perioperative outcomes in patients with biliary atresia in the US.

STUDY DESIGN

We examined hospitalizations in infants aged <1 year using the National Inpatient Sample database for 2000-2011. We identified cases using the International Classification of Diseases, Ninth Revision, Clinical Modification codes for biliary atresia and HPE. Multivariable logistic regression models were used to examine association between select factors and age at HPE, as well as adverse perioperative outcomes.

RESULTS

Our analysis of 1243 biliary atresia hospitalizations showed that only 37.7% of patients had HPE in the first 60 days of life. Patients who underwent HPE after 60 days of age were uninsured, were more likely to be black (aOR, 4.22; 95% CI, 1.49-11.95), less likely to be admitted at a teaching hospital (aOR, 0.27; 95% CI 0.10-0.79), and less likely to have a concomitant congenital malformation (aOR, 0.49; 95% CI 0.25-0.98). Patients with delayed age at HPE incurred significantly higher hospital costs ($57 914 vs $34 074; P = .026). Delayed age at HPE and weekend admission were independently associated with increased odds of adverse perioperative outcome (aOR, 1.09; 95% CI, 1.01-3.02 and 3.98; 95% CI, 1.67-9.46, respectively).

CONCLUSION

Current outcomes in patients with biliary atresia in the United States are suboptimal and result in higher costs. The specific factors associated with delayed care are further evidence that universal health care and screening are needed for all infants, along with systematic referral of potential patients with biliary atresia to specialized health centers.

Multiple orifices and cholangiography with a "fire-like" appearance after Kasai hepatoportoenterostomy for biliary atresia

A 21-year-old female underwent a Kasai hepatoportoenterostomy with Roux-en-Y reconstruction for typeIII biliary atresia at age 63 days. At the age of 19 years, she developed cholangitis and CT scan revealed hepatolithiasis. She presented for treatment of the intrahepatic stone and the hepatportoenterostomy was directly visualized with double-balloon endoscopy (DBE). Endoscopic findings showed multiple intrahepatic bile ducts open to the jejunum through multiple orifices. Cholangiography showed narrowing of intrahepatic bile duct branches with a "fire-like" appearance. These findings have not been previously reported, since endoscopic approaches to patients with a hepaticojejunostomy were limited. DBE was useful to directly visualize the anastomosis in a patient status-post the Kasai operation for biliary atresia with a Rouxen-Y reconstruction.

Early type I collagen deposition is associated with prognosis in biliary atresia

BACKGROUND

Biliary atresia (BA) is a cholestatic liver disease of children that progresses to hepatic fibrosis. BA is the main indication of pediatric liver transplantation (LTx). Histopathological markers in liver biopsies could be useful for predicting progression to end-stage disease.

OBJECTIVE

To establish histopathological or immunohistochemical markers in liver biopsies of BA patients and correlate those markers with prognosis.

METHOD

Histological analysis of biliary alterations and morphometric assessment of liver fibrosis were performed, in addition to indirect immunofluorescence assays (IF) for type I, III, IV and V collagens in initial and final liver biopsies of 36 patients with BA who underwent Kasai hepatoportoenterostomy (KPE) and LTx in the last 20years at a single center.

RESULTS

Histopathological markers had no correlation with evolutive time until LTx. The perisinusoidal deposition of type III and V collagens was more prominent in the initial biopsies (p<0.01), whereas deposition of type I and IV collagens indicated progression (p<0.01). Patients with large amounts of perisinusoidal type I collagen in the initial biopsies had worse progression time curves until LTx (p=0.04).

CONCLUSION

Morphometric assessment of perisinusoidal deposition of type I collagen by IF in the initial biopsy can correlate with progression time to LTx in post-surgical BA.
