Graft versus host-like illness in a child with phenobarbital hypersensitivity

Abstract

A child in whom a phenobarbital hypersensitivity drug reaction developed which consisted of fever, a pruritic desquamating erythrodermic rash, alopecia, icterus, protein-losing enteropathy, myositis, and nephritis, is described. Laboratory studies demonstrated eosinophilia, elevated serum IgE, and elevated T suppressor/cytotoxic cells in the peripheral blood. Findings from biopsy specimens of skin and jejunum suggested a cell-mediated pathogenesis, and lymphoproliferative studies of the patient's mononuclear cells revealed a positive response to phenobarbital. The clinical findings and laboratory studies suggested an autoimmune cell-mediated hypersensitivity reaction triggered by phenobarbital.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

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.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
