OBJECTIVE: The most common severe exfoliative condition is toxic epidermal necrolysis (TEN), also known as Lyell's syndrome, for which patients may sometimes require admission to hospital burns units. This study analyses the experience of the authors and results in this condition at the Cruces University Hospital in Bilbao, Spain.
METHOD: Over the last 22 years, the authors carried out a retrospective analytical observational study of TEN cases at the hospital and analysed risk factors including age, associated comorbidities, percentage of body surface area affected, positive bacterial culture, and treatment strategies used to assess their potential influence on prognosis.
RESULTS: The results indicated an association between mortality and age (ρ (rho)=0.60, 95% CI [0.29, 0.79], p<0,001), ocular (ρ=0.58, 95% CI [0.28, 0.78], p<0.001), oropharyngeal (ρ=0.64, 95% CI [0.36, 0.81], p<0.001), genitourinary (ρ=0.58 CI [0.28, 0.78], p<0.001) respiratory mucosa involvement (ρ=0.53, 95 % CI [0.28, 0.78], p<0.001) and bacteraemia (ρ=0.44, 95% CI [0.17, 0.64], p=0.020). Bacteraemia also showed a higher incidence in elderly patients (ρ=0.4, 95% CI [0.03, 0.67], p=0.033) and in those with a higher Score for Toxic Epidermal Necrolysis at admission (ρ=0.51, CI [0.17, 0.74], p=0.006). A reduction in mortality was found in patients who received systemic treatment; cyclosporine, etanercept or a combination of both (ρ=-0.44, Cl [-0.70, -0.09], p=0.018).
CONCLUSION: TEN is a rare but serious exfoliative condition. Traditionally, management of denuded skin was seen as the main prognostic factor; yet, systemic damage, especially to the respiratory mucosa, significantly increases mortality risk. While life support is crucial and recovery is possible, preventing long-term sequelae relies on effective care protocols. Current treatments may offer benefits, though their efficacy remains unclear. Clinicians in burns units should develop standardised protocols and collaborate on long-term studies to enhance patient care.
