Generalized Pustular Psoriasis associated with Psoriatic Arthritis, Tonsillitis and sinusitis
Generalized Pustular Psoriasis associated with Psoriatic Arthritis, Tonsillitis and sinusitis suggests a new study published in the Journal of Dermatology.
Of those patients diagnosed with generalized pustular psoriasis (GPP) in Japan, approximately 30% have a prior psoriasis vulgaris (PsV) diagnosis. Therefore, understanding factors associated with a GPP diagnosis is essential for early diagnosis of GPP in patients with PsV.
This retrospective cohort study was conducted to identify associated factors for GPP diagnosis in patients with PsV. Eligible patients with two confirmed diagnoses of PsV with/without a confirmed GPP diagnosis (International Classification of Disease 10th revision codes L40.0 and L40.1, respectively) were identified from the Japanese Medical Data Center database (JMDC) (July 1, 2005–January 31, 2019). Weighted logistic regression was used to identify associated factors (based on recorded comorbidities) between the PsV only and PsV with GPP cohorts. Odds ratios (ORs) of ≥1.5, associated with a high probability of a GPP diagnosis, were reported for factors with ≥5 patients/cohort.
The time from event to GPP diagnosis was evaluated. The highest associated factor for GPP diagnosis was psoriatic arthritis (OR 20.2, 95% confidence interval [CI] 17.06–23.92, P < 0.0001), which also had the shortest time from event to GPP diagnosis (median 119 days). Other comorbidities associated with GPP diagnosis were other psoriasis, tonsillitis, and sinusitis. Treatments associated with GPP diagnosis included systemic corticosteroids (OR 2.19, 95% CI 1.98–2.43, P < 0.0001; median time from treatment initiation to GPP diagnosis 180 days). Other associated treatments (other immunosuppressants, interleukin [IL]-17 or IL-23 inhibitors, and phototherapy) had a delay of ≥1 year from treatment initiation to GPP diagnosis. Back pain, headache, and fever were also identified as associated with a GPP diagnosis. Patients with PsV requiring systemic therapies are more likely to receive a GPP diagnosis than those not requiring systemic treatment.
These data will help identify patients with PsV at high risk of developing GPP and potentially support early GPP diagnosis.
