We sought to assess the activity of thiopurine methyltransferase (TPMT) in 14,545 Spanish patients with different diseases amenable to treatment with azathioprine/6-mercaptopurine (6-MP), and to evaluate the proportion of patients with low TPMT activity and therefore a higher risk of myelotoxicity with these drugs. TPMT activity in red blood cells ...

Adult-onset thymoma may be responsible for several diseases, such as pure red cell aplasia, myasthenia gravis, and immunodeficiency (Good's syndrome). Thymectomy does not always improve the patient's condition, and may even produce additional symptoms. Its pathogenesis is still not entirely understood, but autoimmunological processes and bone marrow defect are the ...
