When a pregnant woman presents with itching in skin of normal appearance and a raised peak total bile acid concentration in the 40–99 µmol/L range, this is classified as moderate intrahepatic cholestasis of pregnancy (ICP) — a specific severity tier with its own structured management pathway.

Clinical Scenario

Itching in skin of normal appearance with a raised peak random total bile acid concentration of 40–99 µmol/L — moderate ICP. Bile acid elevation at this level warrants targeted symptom management and specific guidance on birth planning.

Treatment Overview

Management includes topical agents to relieve skin symptoms and antihistamine agents to reduce itching. Additional assessment and planning steps may be indicated in selected cases. The complete sequenced regimen — including all criteria, decision points, and management steps — is available via the full protocol.

This is a partial summary only. The full protocol contains the complete evidence-based regimen.

The diagnosis of ICP should be considered in pregnant women who have itching in skin of normal appearance and raised peak random total bile acid concentration of 19 micromol/L or more.
Moderate ICP: itching and raised peak bile acid concentrations 40–99 micromol/L.
Consider topical emollients such as aqueous cream (with or without menthol added) to ameliorate skin symptoms.
Consider antihistamine agents, such as chlorphenamine, particularly at night although the effectiveness of this treatment is uncertain in women with ICP.
Consider planned birth at 38–39 weeks' gestation in women with moderate ICP with peak bile acids 40–99 micromol/L and no other risk factors; advise them that the overall risk of stillbirth is similar to the background risk until 38–39 weeks' gestation.
