Copeptin decrease from admission to discharge has favorable prognostic value for 90-day events in patients admitted with dyspnea.

abstract：Background:Anti-mitochondrial autoantibodies (AMA) detected by indirect immunofluorescence (IIF) on rodent tissues are the diagnostic marker of primary biliary cholangitis (PBC). However, up to 15% of patients with PBC are AMA-negative by IIF. In the effort to close the serological gap and improve the diagnostic sensit...
