Evaluation of Laboratory Follow-up in Acne Patients Treated With Isotretinoin.

There is a lack of consensus of the frequency of follow-up of laboratory parameters during isotretinoin treatment. We conducted a retrospective analysis of the changes in laboratory parameters used in daily practice for patients with acne who were treated with isotretinoin to determine the optimum test repetition frequency. Patient demographic data; cumulative isotretinoin doses; alanin transaminase (ALT), aspartate transaminase (AST), γ-glutamyltransferase (GGT), creatinine kinase (CK), low-density lipoprotein cholesterol (LDL-C), and triglyceride (TG) levels during treatment were recorded.
