Monitoring the Antiphospholipid Syndrome:TOXicity of Drugs (APSTOX)

Study Overview
=================
Brief Summary
-----------------
Several drugs and chemotherapies seem to have an impact on the immune system. This study investigates reports of immune toxicities such as antiphospholipid syndrome, including the International classification of disease ICD-10 for treatments in the World Health Organization (WHO) global Individual Case Safety Report (ICSR) database (VigiBase).

Detailed Description
-----------------
Several drugs and chemotherapies seem to have an impact on the immune system and are responsible of a wide range of immune side effects such as antiphospholipid syndrome. Those are poorly described, due to the modificationof the pharmacopeia, and the recent recognition of several of these adverseevents. This study investigates the main characteristics of patients affected by immune side effects imputed to drugs in particular antiphospholipid syndrome. A causality assessment according to the WHO-UMC (World Health Organization - Uppsala Monitoring Center) is systematically applied.
