Prognosis after Hospitalization for Erythroderma

Area of Science:

• Dermatology
• Clinical Epidemiology
• Public Health

Background:

• Erythrodermic psoriasis (EP) and erythroderma exfoliativa (EE) are severe, acute inflammatory skin conditions with high mortality risk.
• Understanding the comparative mortality of EP and EE versus other conditions is vital for clinical management and public health strategies.

Purpose of the Study:

• To estimate the 3-year mortality hazard ratios (HRs) for patients hospitalized with EP or EE.
• To compare mortality risks of EP and EE against general population controls, psoriasis vulgaris patients, and toxic epidermal necrolysis (TEN) patients.

Main Methods:

• A retrospective cohort study identified patients hospitalized for EP (n=26) or EE (n=48) between 1997-2010.
• Mortality data were compared with matched general population controls, patients with psoriasis vulgaris (n=1,998), and patients with TEN (n=60).
• Adjusted hazard ratios (HRs) for 3-year mortality were calculated.

Main Results:

• Patients with EP and EE faced significantly higher 3-year mortality risks compared to general population controls (HRs 4.40 and 2.16, respectively).
• Mortality risk for EP and EE was also elevated compared to psoriasis vulgaris (HRs 1.83 and 1.28, respectively).
• However, mortality risk was significantly lower for EP and EE compared to toxic epidermal necrolysis (TEN) (HRs 0.38 and 0.50, respectively).

Conclusions:

• Hospitalization for Erythrodermic Psoriasis and Erythroderma Exfoliativa is associated with a substantial increase in 3-year mortality.
• While less fatal than TEN, these conditions carry a higher mortality burden than general populations or typical psoriasis vulgaris.
• Close medical follow-up and management are strongly advised for patients diagnosed with EP and EE.
