Prevalence of liver abnormality in early syphilis.

Hepatic structure and function of 22 unselected patients with early syphilis was assessed. In 20 (91%) routine hepatic tests or bromsulphalein retention showed mild non-specific abnormalities. Minor changes in hepatic structure were present in 12 (55%), in three of whom intrahepatic spirochaetes were found. The only patient who had hepatomegaly also had splenomegaly. Observed changes in hepatic structure correlated with neither physical signs nor results of biochemical tests. Hepatic changes in early syphilis are common but frequently subclinical.
