Summary
Toxic epidermal necrolysis (TEN) is a severe drug reaction causing skin detachment. Etanercept treatment halted epidermal detachment within 48 hours, leading to complete healing in a rare case of phenobarbital-induced TEN.
Area of Science:
- Dermatology
- Pharmacology
- Immunology
Background:
- Toxic epidermal necrolysis (TEN) is a rare, severe adverse drug reaction.
- It involves massive apoptosis and widespread epidermal and mucosal detachment.
- No definitive gold standard therapy exists for TEN.
Observation:
- A case of phenobarbital-induced TEN in a 59-year-old woman is presented.
- Etanercept treatment was initiated for the patient.
- Epidermal detachment ceased 48 hours after starting etanercept.
Findings:
- Complete healing of TEN occurred within 20 days of etanercept treatment.
- This is the second reported case of successful TEN treatment with etanercept.
- Etanercept demonstrates potential efficacy in managing severe drug reactions like TEN.
Implications:
- Etanercept may be a viable therapeutic option for drug-induced TEN.
- Further research is warranted to confirm etanercept's role in TEN management.
- This finding contributes to understanding treatment strategies for severe cutaneous adverse reactions.

Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
Cytotoxic Edema: Pathophysiology
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
