Reflex AMA and ANA testing

Reflex AMA and ANA testing: Measurement of alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT) on routine pre-hospitalization blood samples, with reflex testing for anti-mitochondrial antibodies (AMA) and anti-nuclear antibodies (ANA) in case of abnormal results.

Study summary

Primary biliary cholangitis (PBC) is a chronic autoimmune disease characterized by progressive destruction of the small intrahepatic bile ducts, leading to cholestasis and potential progression to cirrhosis. Prognosis is favorable when diagnosed and treated early, while diagnostic delay is common. Diagnosis is based on elevated ALP and the presence of autoantibodies (AMA/ANA), but the disease is often asymptomatic and detected late.It predominantly affects women aged 40-60 years, and evidence suggests underdiagnosis, highlighting the need for screening strategies in at-risk populations.

Inclusion Criteria: * Female sex, * age ≥ 40 years, * patients attending the pre-hospitalization service for planned admission requiring the measurement of alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT or gamma-GT) as part of routine clinical practice; * the patient is able to understand the study information and provide informed consent. Exclusion Criteria: * Previous diagnosis of Primary Biliary Cholangitis (PBC) or other liver disease, * patients unable to understand the study information and for whom informed consent cannot be obtained, * patients with known conditions associated with elevated ALP: pregnancy, extrahepatic biliary obstruction (e.g., choledocholithiasis, biliary or pancreatic neoplasms), hepatic neoplasms or metastases, Paget's disease, bone neoplasms or metastases, hyperparathyroidism.

Primary outcome measure(s)

  • Percentage of patients diagnosed with primary biliary cholangitis identified through a reflex testing algorithm (ALP/GGT → AMA/ANA) — 2-10 months
    Proportion of women with elevated alkaline phosphatase (ALP) levels undergoing reflex testing (automatic measurement of AMA and ANA) who receive a diagnosis of primary biliary cholangitis according to standard clinical criteria. Results will be reported as a percentage of the total number of patients undergoing reflex testing.
