BACKGROUND & AIMS Anti-tumor necrosis factors (anti-TNF) including infliximab, adalimumab and certolizumab pegol are used to treat Crohn's disease (CD) and ulcerative colitis (UC). Paradoxically, while also indicated for the treatment of psoriasis, anti-TNF therapy has been associated with development of psoriasiform lesions in IBD patients and can compel discontinuation of therapy. We aim to i...
BACKGROUND Tumor necrosis factor-α (TNF-α) inhibitors, such as infliximab, adalimumab, and certolizumab pegol are effective agents in the treatment of inflammatory bowel disease. Some individuals undergoing anti-TNF-α therapy for Crohn's disease or ulcerative colitis develop psoriasiform lesions. This is a paradoxical finding, as classical psoriasis is known to respond to these agents. PURPOS...
Psoriasiform drug eruptions are very rare and generally characterized as erythematous, thick, dry, squamous, and demarcated plaques, resembling those of idiopathic psoriasis (1). Drugs may result in the exacerbation of pre-existing psoriasis or initiation of de novo psoriatic lesions (2). Apixaban, a reversible direct inhibitor factor Xa, is a novel anticoagulant, and its side effects mainly in...
Graft-versus-host disease (GVHD) is a common complication of bone marrow transplantation (BMT) that can be classified as acute or chronic. Chronic GVHD, which usually occurs more than 3 months after BMT, includes typical lichenoid or sclerodermatous lesions. Psoriasiform eruption is a rare clinical manifestation of chronic GVHD, and there have been no reports of psoriasiform chronic GVHD associ...
BACKGROUND & AIMS Psoriasiform and eczematiform lesions are associated with anti-tumor necrosis factor (TNF)-α therapies. We assessed clinical characteristics, risk factors, and outcomes of skin disease in patients with inflammatory bowel diseases that presented with psoriasiform and eczematiform lesions induced by anti-TNF-α agents. METHODS We studied 85 patients (69 with Crohn's disease, 15...
BACKGROUND We analysed incidence, predictors, histological features and specific treatment options of anti-tumour necrosis factor α (TNF-α) antibody-induced psoriasiform skin lesions in patients with inflammatory bowel diseases (IBD). DESIGN Patients with IBD were prospectively screened for anti-TNF-induced psoriasiform skin lesions. Patients were genotyped for IL23R and IL12B variants. Skin ...
BACKGROUND Psoriasis has different clinical variants, which mimic diverse dermatological conditions and may require a histopathological confirmation of the diagnosis. Studies to establish a clinicohistopathological concordance (and its determinants), in psoriasis and psoriasiform dermatitis are lacking. AIMS The present study was designed (a) to correlate the clinicohistopathological features...
Psoriasiform Keratosis is a rare clinic entity. The etiopathogenesis remains unknown and the disease is characterized by a solitary, scaly or keratotic papule, or plaque mainly located on the extremities. Histopathological features closely resemble those of psoriasis. We report the case of a 70-year-old woman presenting a solitary and asymptomatic keratotic plaque, located on the back of the le...
Psoriasiform lesions are characterized by hyperproliferation and aberrant differentiation of epidermal keratinocytes, accompanied by inflammation, leading to a disrupted skin barrier with an abnormal stratum corneum. The expression and proteolytic processing of caspase 14, a member of the caspase family which is associated with epithelial cell differentiation, planned cell death, and barrier fo...
Psoriasis is a complex genetic disease of unresolved pathogenesis with both heritable and environmental factors contributing to onset and severity. In addition to a disfiguring skin inflammation, approximately 10-40% of psoriasis patients suffer from destructive joint involvement. Previously, we reported that the CD18 hypomorphic PL/J mouse carrying a mutation resulting in reduced expression of...
