Tumor necrosis factor (TNF)-α inhibitors are widely used for the treatment of inflammatory diseases. One of the side effects of TNF-inhibitors is the development of a psoriatiform eruption, also known as paradoxical psoriasis. In this case report, we describe a patient with this side effect after treatment with adalimumab and etanercept.
Case Report
A 45-year-old female was treated with adalimumab 40 mg once every 2 weeks for pustulosis palmoplantaris and psoriatic arthritis. After 2 injections, the patient developed a psoriatiform eruption on her body, which improved after discontinuation of adalimumab but worsened after treatment with etanercept 50 mg twice weekly. Eventually, the patient was treated with topical corticosteroids and ustekinumab 45 mg once every 3 months with a complete remission of the psoriatiform eruption.
Discussion
Several case reports and reviews have been published in recent years which describe patients with a psoriatiform eruption after treatment with TNF-α inhibitors. The pathogenesis that causes this psoriatic eruption is unclear. In conclusion, we describe a patient with a psoriatiform eruption after treatment with adalimumab and etanercept. This patient had to discontinue the treatment and eventually had a complete response after treatment with topical corticosteroids and treatment with ustekinumab.
Tumor necrosis factor (TNF)-α inhibitors have been of great benefit in the treatment of inflammatory diseases, such as Crohn’s disease, rheumatoid arthritis, ankylosing spondylitis and psoriasis [1]. With the increased use of TNF-α inhibitors, it is important to recognize and understand the cutaneous adverse effects [2]. A number of case reports and case series describe patients who develop psoriasiform eruptions while on TNF-α inhibitors. These eruptions can exist of plaque, pustular or guttate psoriasis. Nail psoriasis has also been seen, with characteristic features of onycholysis, discoloration and pitting. All TNF-α inhibitors including inflixmab, adalimumab and etanercept can be responsible for these reactions [1‐4].
In this case report, we describe a patient with pustulosis palmoplantaris, who had worsening of her primary skin disease and developed a generalized psoriasiform eruption after treatment with adalimumab and etanercept.

Case Report
A 45-year-old woman presented at the outpatient clinic because of disabling skin lesions. On examination, we found erythematous and squamous papules and plaques on her trunks, limbs, palms of her hands, soles of her feet, scalp and dystrophic nails of both hands and feet (Fig. 1). The lesions had started 2 months earlier, after starting treatment with adalimumab 40 mg once every 2 weeks. This patient was known from 7 years before with pustulosis palmoplantaris and psoriatic arthritis. Because of this arthritis, her rheumatologist started treatment with adalimumab. Previous treatments were triamcinolone injections (ineffective), leflunomide (Arava), methotrexate, acitretin, prednisone (all four were stopped because of side effects) and UVB phototherapy.

After the first injection of adalimumab, the patient experienced a positive effect on her pustulosis palmoplantaris, but after the second injection the lesions became worse and an itchy rash started on the rest of her body. She was given topical therapy with potent corticosteroid creams and the treatment with adalimumab was stopped. Despite this, the lesions especially of her hands and feet got worse, leading to immobility, and the patient was therefore admitted to our clinical dermatology ward.
Biopsies were taken from the palm of her hand and from one of the lesions on her arm (Fig. 2). The biopsies showed hyper- and parakeratosis, subcorneal pustels with neutrophilic granulocytes and spongiosis. A perivascular inflammation with extravasation of neutrophilic granulocytes was found. A diagnosis of pustulosis palmoplantaris with a psoriatic eruption caused by adalimimab was made.

Blood examination showed a slightly elevated C-reactive protein level and leucocytosis. Antibodies against adalimumab could be detected (95 AE/ml). The adalimumab levels were measured by means of enzyme-linked immunosorbent assay, performed at the Laboratory for Monoclonal Therapeutics, Sanquin Diagnostic Services. The adalimumab blood serum level was 0.1 μg/ml.

Treatment was switched to etanercept 50 mg twice weekly in combination with systemic erythromycin 500 mg 4 times daily (Figs. 3, 4). After 2 months, this treatment also failed. Methotrexate (which was given in combination with the last therapy) had to be stopped because of subjective side effects.

After discontinuing etanercept treatment and starting treatment with clarithromycin 300 mg three times daily, her skin condition was slowly getting better. The patient was treated in our daycare center multiple days a week with different topical therapies, UVB photo-therapy and multiple antibiotics. The pustulosis palmoplantaris and the psoriatic eruption were slowly getting better. Because of worsening of her psoriatic arthritis, treatment with ustekinumab was started. Eventually, the psoriatic eruption that was started after treatment with adalimumab was gone and the pustulosis palmoplantaris on hands and feet improved.

Discussion
Anti-TNF-α therapies are widely used in the treatment of inflammatory disorders, such as psoriasis, arthritis and inflammatory bowel diseases. Side effects of these treatments have been reported, including a de novo or worsening of psoriatic eruption. This adverse reaction is also known in the literature as paradoxical psoriasis. Many case reports and case series have been published to describe these patients who use either infliximab, adalimumab or etanercept, with an incidence of 1–5% [1‐4]. In larger case studies, no predisposing factors for paradoxal psoriasis have been described. Only a minority of the patients treated with anti-TNF-α agents had a history of psoriasis or a family member with psoriasis.
In a systematic literature review from 1996 to 2009, 207 patients suffering from paradoxal psoriasis were analyzed. Patients were treated with anti-TNF-α agents for rheumatoid arthritis, seronegative spondylarthropathy, inflammatory bowel disease, psoriasis or others. Patients were treated with either infliximab (59%), etanercept (19%) or adalimumab (22%). The majority of these patients developed plaque-type (50%), pustular (56%) or guttate psoriasis (12%). Most patients (67%) were able to continue their anti-TNF-α treatment, and 57% of them had a complete or partial remission of the psoriatic eruption [3].
Another systematic review showed similar results [5]. In patients whose treatment was discontinued, 32% had a complete remission of the psoriatic eruption. Patients who continued their therapy showed a complete remission of 29%. Of the patients who switched to another anti-TNF-α therapy, 24% showed a complete remission [5]. Other studies showed no beneficial effect after switching to another anti-TNF-α therapy [2].
Biopsies taken from the psoriatic lesions caused by anti-TNF-α therapies showed in most cases a psoriatiform pattern, but a lichenoid pattern, spongiosis, epidermal edema and neutrophilic infiltration have also been reported [6, 7]. The pathogenesis that causes this psoriatic eruption is unclear. There are some hypotheses that can explain the eruption. MxA (myxoprotein A) is a protein that is induced by interferon (IFN) alpha and beta. Biopsies taken from the psoriatic eruption in patients with TNF-α inhibitors show an increase in this MxA protein in comparison with healthy controls and patients with a psoriasis vulgaris. Anti-TNF-α therapies produce a decrease of TNF-α, but can also induce high levels of IFN, which may lead to an increase of MxA protein [6].
IFN-α can also induce an increase of specific receptors, including the chemokine receptor CXCR3. This may lead to an increase of T-cells and neutrophils in the skin, thus mimicking psoriasis. Pro-inflammatory cytokines, induced by IFN-α, can stimulate the Th17 pathway, also leading to psoriasis [8, 9]. This may also explain why ustekinumab, which is a IL23 blocker, has a beneficial effect on this type of psoriatiform eruption.

Recently, Cabaleiro et al. found an association between genetic polymorphism and paradoxal reactions in patients with psoriasis who were treated with anti-TNF-α therapies. Five single-nucleotide polymorphisms were associated [10].
Collamer et al. [11] proposed an algorithm for the treatment of anti-TNF-α-induced paradoxical reaction. Depending on the severity of the paradoxical reaction, patients should be treated aggressively with topical corticosteroids, keratolytics and vitamin D analogs and if necessary additionally with ultraviolet phototherapy, methotrexate, acitretin and ciclosporin. For patients who continue to have recalcitrant skin disease, biologic therapy with other than TNF antagonists can be considered. For instance, in patients suffering from psoriatic arthritis and Crohn’s disease, treatment of paradoxical psoriasis with ustekinumab may be effective [12].
Conclusion
In this case report, we present a patient with a palmoplantar pustulosis and psoriatic arthritis, who developed a psoriatiform eruption after treatment with adalimumab. Different topical and systemic psoriasis treatments did not have a beneficial effect on the psoriatic lesions. Switching to etanercept, another anti-TNF-α treatment, showed a partial response at first, but later this patient developed the same psoriatiform eruption. Treatment with ustekinumab eventually resulted in an almost complete remission of the skin lesions and good control of her psoriatic arthritis.
