There is one clinical trial.
Azathioprine (AZA) has long been used in dermatology in treating autoimmune bullous dermatoses and generalized eczematous disorders as well as some photodermatoses. Its metabolic process inside human body and its side effects relies on genetic polymorphism of some enzymes such as thiopurine s-methyltransferase (TPMT) and inosine triphosphate pyrophosphatase gene (ITPA). This study aims to analyze the relative contribution of TMPT and ITPA mutations to the development of toxicity induced by AZA treatment and to detect the correlation of the genetic polymorphism.
The aim of our study was to determine the relative contribution of, TMPT(A719G) and ITPA(C94A) mutations to the development of toxicity induced by AZA treatment in dermatology patients and to detect the correlation of these two genetic polymorphism. --- A719G ---
Description: current treatment to nausea/vomiting adverse effects induced by azathioprine combined with pre-therapeutic genetic screening, especially polymorphism ITPA C94A, may reduce the possibility for developing hematopoietic toxicity and/or hepatotoxicity.Measure: Genetic polymorphism tests before azathioprine therapy may reduce toxicity Time: 2008.1.1
