a patient with eruptive psoriasis need to start biologic treatment but have an increased liver enzymes X3 of the normal value, what treatment would you suggest ? I am looking for new Articles providing the latest therapy.
First of all assess for the cause of transaminitis; was the patient on Mtx at any point and when was the last dose taken? Repeat transaminase level, rule out viral hepatitis, take a drug history to look for hepatotoxic drugs, abdominal ultrasound if you're suspecting NASH etc.
Assess the severity (extent and disability) of the psoriasis
If not severe (Limited plaque psoriasis i.e. < 20% BSA or PASI20% BSA or PASI>10), some of the systemic/other agents which (according the literature) are not hepatotoxic are:
Narrow band UVB: slower onset of action; good for long term maintenance
Cyclosporine: quick onset of action, good for quick induction of remission
Apremilast: hepatic impairment does not alter its pharmacokinetics hence no dose adjustmest is required (1) and no pre-treatment tests are required (2). It is indicated when other systemic agents are contraindicated (2).
Feel free to add inputs if anything important was missed.
