Syphilis: an important cause of infectious hepatitis

The UK incidence of infectious syphilis has risen sharply over the last 10 years; however, its diagnosis can be overlooked in patients who fail to disclose risk factors for its acquisition. This patient presented with hepatitis as part of a multisystemic illness and was investigated extensively before being diagnosed with secondary syphilis. The delay to diagnosis and treatment resulted in irreversible disablement. Syphilis should be considered in the differential diagnosis of hepatitis of uncertain aetiology. In addition, due to the similar presentation and risk factors for acquisition, we suggest that syphilis serology should be performed concomitant to all HIV tests, particularly those from outside the genitourinary medicine clinic setting.
