The project will amalgamate data from several large Indian centers to describe the genotype, clinical spectrum, natural course, genotype-phenotype correlation, outcome, and response to medical therapy in Indian children with progressive familial intrahepatic cholestasis (PFIC). This will be the first such Indian registry of children with PFIC. There are currently limited single-center studies describing the genotype, natural course, and outcome of Indian children with PFIC.
Data will be collected retrospectively from the participating centers across the country. Only genetically confirmed cases would be included.
There is a lack of robust literature from India on PFIC. The study would be the first to extensively describe the genotype of Indian children with PFIC and their natural course. Being a multicentric study, the results generated would therefore be applicable to the whole of the country. Understanding the prevalent genotypes in the Indian population and their related phenotype would help both the individual management decisions of these patients and further policy-making for their diagnosis and treatment. With the advent of genetic diagnosis through sequencing techniques and these tests becoming more affordable, every Indian center is now diagnosing a fair number of these cases which used to go undiagnosed previously. This has changed the landscape of cholestatic liver disease in children where PFICs are now the most prevalent pediatric cholestatic disorder. European studies have demonstrated 2 common mutations where patients respond very well to surgical biliary diversion and have good native liver survival. These mutations have rarely been reported in India. Results from this study could thus guide appropriate decision-making based on outcome and help choose the modality of treatment for the individual patient - medical, surgical biliary diversion, or liver transplantation.
33 studies on the registry are indexed under Cholestasis, progressive familial intrahepatic 1; 13 are open to participants now.
This study's planned enrollment of 200 is close to the median of 200 across 17 observational studies indexed under Cholestasis, progressive familial intrahepatic 1.

All genetically confirmed cases of progressive familial intrahepatic cholestasis (PFIC)
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Native liver survival (in percentage) at the latest follow up in different types of PFIC
The proportion of patients of each subtype of PFIC who have survived with their own with their native liver till the time of last follow up
Time frame: Through study completion - average of 1 year
Describe the spectrum of genetic mutations in Indian children with familial intrahepatic cholestasis
This objective would be assessed by studying the frequency of each of these subtypes of PFIC and describing the various genotypes under each subtype.
Time frame: Through study completion - average of 1 year
Genotype-phenotype correlation in Indian children with various types of progressive familial intrahepatic cholestasis
Well defined clinical parameters (jaundice, pruritus, presentation, presence of cirrhosis) and clinical end points (death, liver transplantation, native liver survival) would be used to describe the genotype-phenotype correlation. We will try to club various mutations into categories based on the type of mutations to better assess the genotype-phenotype correlation.
Time frame: Through study completion - average of 1 year
Analyse the natural course after surgical biliary diversion in Indian children with various types of progressive familial intrahepatic cholestasis
We will analyze the response to surgical biliary diversion in various types of PFIC with emphasis on identifying the genotypes likely to gain maximum benefit through this procedure. Biochemical parameters to assess/ predict the response would be evaluated by regression analysis.
Time frame: Through study completion - average of 1 year
Complications after liver transplantation in children with various types of progressive familial intrahepatic cholestasis till the time of last follow up
The proportion of children going for liver transplantation at various time points would be assessed. Genetic, clinical or biochemical parameters predicting need for imminent/ future liver transplantation would be determined by regression analysis.
Time frame: Through study completion - average of 1 year
Proportion of patients surviving with native liver in uncommon variants of progressive familial intrahepatic cholestasis
Describe the prevalence, natural course and outcome of uncommon variants of progressive familial intrahepatic cholestasis in Indian children
Time frame: Through study completion - average of 1 year
Develop and maintain a registry of Indian patients with progressive familial intrahepatic cholestasis (Indian PFIC registry)
A registry (Indian PFIC registry) would be maintained with use of appropriate data managing software.
Time frame: Through study completion - average of 2 years
Plan to share: No — Individual patient data would not be shared with other researchers.
Started Jan 2023 (actual). Primary completion is estimated for Dec 2025, 35 months after the start.
