Secukinumab‐induced paradoxical hidradenitis suppurativa

Paradoxical reactions during treatment with biological agents may be defined as an appearance or exacerbation of a pathological condition that usually responds to this class of drug. Typical examples of paradoxical adverse effect are, among others, palmoplantar pustular and psoriasiform reactions or HS, in patients during a treatment of rheumatoid arthitis or IBD mainly. A few reports have been described an exacerbation of psoriasis1, palmoplantar pustular, or pustular psoriasis eruption with secukinumab. Marasca et al. highlights the immunological complexity that surrounds autoinflammatory diseases showing the potential double pathogenetic face of secukinumab in HS, describing a case of secukinumab‐induced HS and a case of HS caused by adalimumab treatment and controlled by secukinumab therapy. Real world evidence and results from clinical trials with secukinumab for HS, will possibly show the real role that anti‐IL‐17 drugs play in this complex disease.

Impetigo herpetiformis responsive to secukinumab

Treatment of pustular psoriasis in pregnancy is often difficult to manage and is hampered by limited treatment options. We describe herein a patient who was treated with secukinumab after an unsatisfying response to oral steroids and cyclosporin.     

Case of acrodermatitis continua of Hallopeau following psoriasis with atypical clinical presentation

We present a 63‐year‐old Japanese woman who had clinically unique symmetrical skin rashes on her lower face, inframammary area, back and extremities, with some pustules on the cheeks. Skin biopsy specimens showed typical findings of psoriasis, and Psoriasis Area and Severity Index score was 5.9. After the skin lesions were treated successfully with vitamin D3 ointment, pustules developed on the tips of the fingers and toes, with paronychial and subungual involvement. The pathology of the nail matrix was consistent with pustular psoriasis, and the patient was diagnosed with acrodermatitis continua of Hallopeau (ACH) following psoriasis with an unusual clinical presentation. ACH was well controlled with a low dose of cyclosporin. Our patient is a rare case chronologically affected by two diseases in the same category. We confirmed that ACH is a variant of pustular psoriasis, and believe that the patient could provide another clue to determining the entity of ACH.     

Case of acrodermatitis continua accompanied by psoriatic arthritis

Acrodermatitis continua of Hallopeau (ACH) is a rare chronic pustular eruption that predominantly involves the fingertips. The characterization of this disease has been confused. Some have considered it as a separate entity while others as a variant of pustular psoriasis. The presented patient simultaneously had ACH and joint lesions which were diagnosed as psoriatic arthritis. We believe that because ACH may be accompanied by psoriatic arthritis, as in this case, it could be evidence that it is a variant of psoriasis.     

Secukinumab and acitretin as a combination therapy for three clinical forms of severe psoriasis in multi‐drug refractory patients: A case series of high efficacy and safety profile

Secukinumab, the first monoclonal antibody that inhibits interleukin‐17A, has been shown to have rapid and long‐lasting efficacy in the treatment of moderate‐to‐severe psoriasis. However, there are still difficult‐to‐treat cases in which even dose‐escalation fails to provide a clinical response. In such cases, combining secukinumab with a conventional systemic agent may be a rational approach. Although methotrexate is most commonly preferred, acitretin may also be considered a good alternative, with its lower hepatotoxic potential. Data are limited regarding the use of combination therapy of secukinumab and acitretin for psoriasis. We herein present three patients with chronic plaque, generalized pustular and erythrodermic psoriasis, respectively, accompanied by multiple comorbidities, in whom skin clearance could not be achieved with several conventional and biologic therapies (including escalated dose regimens of secukinumab in two patients). Alternatively, we used a combination of secukinumab with low‐dose acitretin, which resulted in a complete or almost complete skin clearance in all patients, with no adverse events or increased toxicity. Based on our real‐life clinical experience with those patients, acitretin seems an effective and safe option to be used in combination with secukinumab. Even in patients who are refractory to multiple drugs including escalated doses of secukinumab, the addition of low‐dose acitretin may be helpful in achieving treatment goals, decreasing the need for switching to another biologic therapy.     

Using oral tetracycline and topical betamethasone valerate to treat acrodermatitis continua of hallopeau

Acrodermatitis continua of Hallopeau (ACH) is a rare type of localized pustular psoriasis. We report the case of a 65-year-old alcoholic woman who had severe inflammatory ACH for 10 years. Initial therapy with sulfasalazine was unsuccessful. The patient was then treated with oral tetracycline and topical betamethasone valerate with occlusive dressing. Her condition improved dramatically after one week.

Successful treatment with interleukin‐17A antagonists of generalized pustular psoriasis in patients without IL36RN mutations

Generalized pustular psoriasis (GPP) is a potentially life‐threatening disease that can be attributed to mutations in IL36RN in a subgroup of patients. In small trials, interleukin (IL)‐17A and IL‐17RA antagonists have been shown to be effective in patients with generalized pustular psoriasis in Japan. We identified seven patients who received the IL‐17A antagonists secukinumab (six cases) or ixekizumab (one case) in two dermatological centers. All patients showed a good or excellent clinical response. Anti‐IL‐17A therapy was well tolerated and ongoing in all patients after an average therapy duration of 12.9 months. Analysis of IL36RN mutation status was performed in six patients, one patient carried a heterozygous mutation, while the other five patients did not show a mutation in IL36RN. This is the first report of a successful treatment of GPP patients without IL36RN mutations responding to anti‐IL‐17A therapy.     

Ustekinumab for the treatment of acrodermatitis continua of Hallopeau refractory to anti‐TNF agents

Acrodermatitis continua of Hallopeau (ACH) is a variant of pustular psoriasis that is often very difficult to treat. Almost all anti‐psoriatic agents have been used in the treatment of ACH. Ustekinumab, a fully human monoclonal antibody of the IgG1 class, is directed to the shared p40 subunit of cytokines IL‐12 and IL‐23. Herein, we present our experience of ustekinumab use in a 50‐year‐old man who was resistant to anti‐tumor necrosis factor‐α agents. Though initial therapy with ustekinumab achieved a sustained response in our patient, after a seven months of interruption, retreatment resulted in a slower and poorer response than the initial regimen. Both responses of our patient reflects: (i) the recalcitrant chronic nature of ACH in some patients, (ii) the value of ustekinumab in ACH treatment, (iii) the fact that, as with other biologics, a loss of response may also occur with ustekinumab when the treatment is interrupted. All these data provides evidence for the fact that the course of ACH is unpredictable and possibly indicate that concerning current biologics used in the treatment of ACH, we have still failed to hit the target we aimed for.     

Epidemiological survey of patients with pustular psoriasis in the Japanese Society for Psoriasis Research from 2017 to 2020

The Japanese Society for Psoriasis Research (JSPR) has been conducting annual epidemiological surveys of patients with pustular psoriasis in Japan since 2017. This study aimed to conduct a recent epidemiological analysis of patients with pustular psoriasis who were enrolled in the JSPR from 2017 to 2020. A total of 291 patients from 131 medical institutions were enrolled, of which 47.4% (138 cases) were males and 52.6% (153 cases) were females. The mean ± standard deviation (SD) age of the patients was 57.4 ± 20.3 years (males, 61.2 ± 17.3 years; females, 54.1 ± 22.1 years). The mean ± SD age of the patients at disease onset was 48.5 ± 22.5 years (males, 50.8 ± 20.6 years; females, 46.4 ± 24.0 years). The types of pustular psoriasis observed included the von Zumbusch type (59.8%), annular pustular psoriasis (8.2%), impetigo herpetiformis (6.5%), and acrodermatitis continua of Hallopeau (4.8%), of which, the majority of the patients with impetigo herpetiformis were female. Among the patients, 58.4% were treated with oral medications and 44.0% were treated with biologics. The most common oral medication prescribed was etretinate (52.4%), followed by corticosteroids (24.7%) and cyclosporin (22.9%). The most common biologics used were IL-17 inhibitors (ixekizumab [28.1%] and secukinumab [22.7%]), followed by tumor necrosis factor (TNF) inhibitors (infliximab [15.6%]) and IL-23 inhibitors (guselkumab [14.8%] and risankizumab [10.2%]). This survey thus provides new and significant information regarding the recent perspective of pustular psoriasis, such as patient characteristics and treatment trends, in Japan.     

Flare-up of pustular psoriasis with fluoxetine: possibility of a serotoninergic influence?

In this article, we report two cases of pustular psoriasis flaring up after fluoxetine administration. A 21-year-old male patient with localized pustular psoriasis became erythrodermic following commencement of fluoxetine. Even though the lesions were unresponsive to cyclosporine A (Cyc A) treatment, dramatic resolution was observed with discontinuation of fluoxetine. A 44-year-old female patient with pustular psoriasis who was on Cyc A and acitretin therapy was given fluoxetine for her psychiatric symptoms. In the following 5 days, her lesions flared. Owing to previous experience, fluoxetine was stopped. Her lesions improved dramatically in the following 3 days. Exacerbation of psoriasis with antidepressant therapy has been rarely described. An extensive review of the literature revealed four such cases, all of which were seen after the use of selective serotonin reuptake inhibitors (SSRI). A serotoninergic influence in the etiopathogenesis of psoriasis may be possible together with a pharmacogenetic difference in the drug metabolism of these patients. Considering the two patients we presented and the patients previously reported in the literature, aggravation of pustular psoriasis by SSRI should be borne in mind.

Efficacy and safety of secukinumab in patients with generalized pustular psoriasis: A 52‐week analysis from phase III open‐label multicenter Japanese study

Generalized pustular psoriasis (GPP) is a severe inflammatory skin disease characterized by the presence of sterile pustules covering almost the entire body and systemic symptoms such as fever. Secukinumab, a fully human‐recombinant anti‐interleukin‐17A monoclonal antibody was indicated for psoriasis vulgaris and psoriatic arthritis in Japan but is not yet investigated for GPP. In this phase III, open‐label multicenter single arm study, the efficacy and safety of secukinumab as monotherapy or with co‐medication was evaluated in 12 Japanese patients with GPP. All the patients received secukinumab 150 mg s.c. at baseline, week 1, 2, 3 and 4, and then every 4 weeks. Two non‐responders were up‐titrated to 300 mg. Change in GPP severity from baseline was evaluated by clinical global impression (CGI) categorized as “worsened”, “no change”, “minimally improved”, “much improved” or “very much improved”. Treatment success was achieved by 83.3% (n = 10) of patients at week 16 (primary end‐point) with CGI evaluated as “very much improved” (n = 9) and “much improved” (n = 1). Moreover, the area of erythema with pustules improved as early as week 1 and resolved by week 16 in most of the patients. The improvements were sustained throughout 52 weeks. Over the 52‐week treatment period, secukinumab was well tolerated with no unexpected safety signals. Nasopharyngitis, urticaria, diabetes mellitus and arthralgia were the frequent adverse events reported. The data from this study shows that secukinumab can become one of the potent treatment options for GPP.     

Acrodermatitis continua of Hallopeau in a patient with myelodysplastic syndrome

Summary Acrodermatitis continua of Hallopeau (ACH) is a rare manifestation of pustular psoriasis which may considerably disable affected patients. In this case report we confirm the efficacy of acitretin in the treatment of ACH and. in addition, describe the course of the myelodysplastic syndrome (MDS) from which the patient was suffering. During acitretin treatment, there was a transformation into acute myeloid leukaemia. We discuss the effect of retinoids on the bone marrow of normal subjects, patients with MDS. and patients with acute myeloid leukaemia.
Our experience in the present case, and the information from the available literature, lead us to advise against the use of the aromatic retinoids, acitretin and etretinate, in patients with MDs. If such treatment is indicated, intensive haematological supervision is mandatory.     

Successful treatment of acrodermatitis continua of Hallopeau with sequential combination of calcipotriol and tacrolimus ointments

Acrodermatitis continua of Hallopeau (ACH) is a rare type of pustular psoriasis affecting the digits. We report on a 43-year-old female patient who had been suffering from ACH for more than 20 years. Despite the fact that the disease was localized on one finger during the whole period, several topical and systemic treatments resulted in only temporary or partial improvement of the lesion. Although the monotherapies with calcipotriol and tacrolimus ointments gave no satisfying results in the long-term management of the disease, the combination of both agents led to a continuous improvement of the patient's skin condition.     

Infliximab in recalcitrant generalized pustular arthropatic psoriasis

Generalized pustular psoriasis is an unstable inflammatory type of psoriasis, with widespread areas of erythema and sterile pustules, associated with fever and systemic symptoms. Infliximab is a monoclonal antibody with anti-TNFalpha activity, approved for use in psoriasis. We describe a male patient with a long history of stable arthropathic psoriasis, hospitalized with a generalized pustular psoriasis and acute exacerbation of articular complaints. The disease was resistant to multiple therapies (acitretin, methotrexate and corticosteroids), so the patient was started on infliximab, with a very rapid response of both cutaneous and articular symptoms. He had complete clearing of lesions at week 12, and marked improvement of the articular symptoms. No recurrence occurred at 8 months of follow-up with infliximab every 8 weeks. Infliximab had an extremely rapid therapeutic action response on a recalcitrant generalized pustular psoriasis. The articular response was also excellent, with significant improvement of quality of life.
