Abstract

Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) is a life-threatening hypersensitivity reaction. Long-term sequelae include dry eyes, visual impairment and psychological complications. TEN is mostly induced by medication; however, viral infections, such as coxsackievirus A6, are known triggers of this disease. However, how to define the role of infection in SJS/TEN is still a problem. Most patients develop SJS/TEN over the course of symptoms of the infection first, and then take medication. Therefore, virus culture and nucleic acid detection at the acute stage cannot predict that the virus itself will indeed produce such a serious reaction. Furthermore, many SJS/TEN patients who are diagnosed with an infection are afraid of receiving the drug rechallenge test. Thus, we report the first case worldwide of a patient who suffered from TEN caused by herpesvirus 7 infection, which was confirmed by both real-time polymerase chain reaction and lymphocyte transformation test.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
