Dear Editor,

Erythrodermic psoriasis (EP) is an uncommon and possibly fatal psoriasis presentation involving more than 80% of the body surface area (BSA).1 Controlled clinical trials and current treatment choices for EP are limited and, compared to plaque-type psoriasis, EP patients seem to have a worse clinical response to standard therapies.1 Guselkumab is a human monoclonal antibody against Interleukin-23 (IL-23), that joins the p19 subunit of IL-23 and has exhibited excellent and sustained treatment effects in moderate-to-severe plaque-type psoriasis.1 However, reports of guselkumab efficacy in EP are scarce. This study aims to report two cases of EP treated with guselkumab with sustained efficacy and perform a literature review of guselkumab in the treatment of EP.

We present a 65-year-old woman with a 4-year history of psoriasis previously treated with topical steroids. Her disease flared involving >90% of her BSA. Skin examination demonstrated symmetrical erythematous scaly plaques (Fig. 1A). A punch biopsy was compatible with psoriasis. Guselkumab (100 mg via subcutaneous injection at week 0 and week 4, followed by a dose every 8 weeks), topical steroids, and emollients were started. The patient achieved a complete response (PASI100) by week 12 (Fig. 1B) and has maintained it for over 32 months. The second case is a 51-year-old man with a 1-year history of plaque-type psoriasis treated with topical steroids. He presented with erythematous plaques on his extremities and trunk that spread to a PASI 40. Histopathological analysis was compatible with psoriasis. Treatment with guselkumab as mentioned previously resulted in complete resolution by week 12 which has persisted for 2-years.

We performed a literature review of EP treated with guselkumab on August 15, 2022, through MEDLINE (PubMed) with keywords erythroderm* AND guselkumab. Of the 10 results, we excluded 3 as they were about other conditions (non-erythrodermic psoriasis, pustulotic arthro-osteitis, palmoplantar pustulosis, palmoplantar psoriasis, psoriatic arthritis, erythrodermic ichthyosis) and 3 that were reviews.

We included 4 articles with 26 patients combined with EP in treatment with guselkumab. Most patients were men (n = 24), and the mean age was 49.9 years.1–4 All patients showed a good response during treatment, except one with concomitant Castleman’s disease and one that withdrew consent from the study.1–4 Sano et al.3 reported 10 (90.9%) patients with “treatment success” at week 16. Ten (90.9%) patients reported a mean PASI of 3.9 (SD = 4.27) with a median improvement of 94.1% by week 52. Chiang et al.1 reported 13 patients in follow-up for 28 weeks, where 8 (61.5%) reached PASI 50 response by week 12. Megna et al.2 reported one patient with PASI 100 at 20 weeks and sustained effect by week 48. Zanelli et al.4 reported a patient with multicentric Castleman’s disease and EP that did not respond to guselkumab therapy.

The two patients reported herein had a PASI 100 response by week 12 with sustained effect at the last follow-up at 24 and 32 months and no adverse events. IL-23 inhibitors have shown higher PASI90 and PASI100 response rates compared to anti-TNF alpha inhibitors in moderate and severe psoriasis with a similar adverse event profile.5 Our review found few cases and case series of EP treated with guselkumab but a high response rate. Reported adverse events were infrequent and mild. Several factors influence treatment decisions, including infections (e.g., tuberculosis or hepatitis B/C), affordability, comorbidities, and accessibility. Our study suggests that guselkumab is an efficient treatment for EP, given the results, safety, and long-term effectiveness it has shown. Comparative studies, that include other biologics like risankizumab and tildrakizumab, are needed to define the best treatment for patients with EP.
