Typical laboratory values include mild anemia, leukocytosis, eosinophilia, elevated erythrocyte sedimentation rate, abnormal serum protein electrophoresis with a polyclonal elevation in the gamma globulin region, and elevated IgE levels.13,68. Von Hebra first described erythroderma (exfoliative dermatitis) in 1868. Loss of normal vasoconstrictive function in the dermis, decreased sensitivity to the shivering reflex and extra cooling that comes from evaporation of the fluids leaking out of the weeping skin lesions all result in thermoregulatory dysfunction that can cause hypothermia or hyperthermia.6 The basal metabolic rate also is increased in patients with exfoliative dermatitis.

Moreover, after granulysin depletion, they observed an increase in cell viability. Federal government websites often end in .gov or .mil. The prognosis of cases associated with malignancy typically depends on the outcome of the underlying malignancy. In conclusion we suggest that therapy with cyclosporine is valuable option with a dosage of 35mg/kg oral or iv for 7days. Even though exfoliative dermatitis is a complex disorder involving many factors, the underlying disease is usually the key determinant of the course and prognosis.

The Nikolskys sign is not specific for SJS/TEN, in fact it is present also in auto-immune blistering diseases like pemphigus vulgaris. Pehr K. The EuroSCAR study: cannot agree with the conclusions. Although the final result of this dual interaction is still under investigation, it seems that the combination of TNF-, IFN- (also present in TEN patients) and the activation of other death receptors such as TWEAK can lead to apoptosis of keratinocytes [44]. Clinical and Molecular Allergy Erythema multiforme StevensJohnson syndrome and toxic epidermal necrolysis. Synthetic bilaminar membranes with silver nitrate have also a role in skin repairing and avoid protein loss through the damaged skin [100, 101]. The most common causes of death in patients with exfoliative dermatitis are pneumonia, septicemia and heart failure. Nutritional support. J Allergy Clin Immunol. Lymphocyte transformation test (LTT) performed as described by Pichler and Tilch [77] shows a lower sensitivity in severe DHR compared to less severe DHR [78] but, if available, should be performed within 1week after the onset of skin rash in SJS and TEN [79].

Toxic epidermal necrolysis and StevensJohnson syndrome. Still, treatment indication, choice and dosage remain unclear, and efficacy yet unproven. Br J Dermatol. Increased level of retinoid acid could be responsible for keratinocytes apoptosis [99]. Since cutaneous function as a multiprotective barrier is so disrupted in exfoliative dermatitis, the body loses heat, water, protein and electrolytes, and renders itself much more vulnerable to infection.
