Data on generalized pustular psoriasis (GPP) in Poland are limited. Therefore, this study aimed to evaluate the demographic and clinical characteristics of Polish patients with GPP. In addition, the effect of the frequency of disease flares and the concomitant presence of psoriasis vulgaris (PV) on patient characteristics was evaluated.INTRODUCTIONData on generalized pustular psoriasis (GPP) in Poland are limited. Therefore, this study aimed to evaluate the demographic and clinical characteristics of Polish patients with GPP. In addition, the effect of the frequency of disease flares and the concomitant presence of psoriasis vulgaris (PV) on patient characteristics was evaluated.In this retrospective study, medical records of patients hospitalized for GPP in dermatology departments of the Polish Generalized Pustular Psoriasis Group were analyzed.METHODSIn this retrospective study, medical records of patients hospitalized for GPP in dermatology departments of the Polish Generalized Pustular Psoriasis Group were analyzed.A total of 90 patients from 14 dermatology centers were included. The median age of patients was 59 (range, 5-85) years, and most patients were female (68.9%). The most common comorbidity was hypertension (43.3%), followed by cardiovascular diseases, diabetes, and hyperlipidemia. The median duration of GPP was 3 years, and the median number of flares was 2. Hospitalization was required in 67% of flares. The main triggering factors were drugs (20.5%) and infections (19.3%). Women and men with GPP differed in terms of age (p < 0.01), distribution of comorbidities, and selected triggering factors (stress: p < 0.05). Almost 25% of patients experienced more than one flare per year. Patients with different frequency of flares did not differ significantly in age, sex distribution, or comorbidities, but those with a higher frequency of flares had a shorter disease duration (median: 0.6 vs. 4.0 years; p < 0.01). In 59.1% of patients, GPP was accompanied by PV. Patients with GPP and PV were younger than those with GPP alone (median: 48.0 vs. 66.0 years; p < 0.01).RESULTSA total of 90 patients from 14 dermatology centers were included.

However, a high rate of flares requiring hospitalization and a significant percentage of patients experiencing more than one flare per year indicate the unmet need in the management of patients with GPP.CONCLUSIONSIn this study, the general demographic and clinical characteristics of patients with GPP were consistent with those described in other studies.
