Axonal sensorimotor polyneuropathy after starting guselkumab.

Guselkumab is an IL-23 inhibitor that binds to the p19 subunit of IL-23 that is highly efficacious and well tolerated for the treatment of moderate-to-severe plaque psoriasis. We report a 20-year-old male who developed sensorimotor axonal polyneuropathy starting treatment with guselkumab, confirmed by neurological examination and serial neurophysiologic studies. His symptoms improved within 5 months of stopping the treatment.

Kindler's Syndrome with Recurrent Neutropenia: Report of Two Cases from Saudi Arabia.

Kindler syndrome (KS) is a rare photosensitivity disorder with autosomal recessive mode of inheritance. It is characterized by acral blistering in infancy and childhood, progressive poikiloderma, skin atrophy, abnormal photosensitivity, and gingival fragility. Besides these major features, many minor presentations have also been reported in the literature.

An atypical pulmonary fibrosis is associated with co-inheritance of mutations in the calcium binding protein genes and .

Background: Pulmonary fibrosis is one of the leading indications for lung transplantation. The disease, which is of unknown aetiology, can be progressive, resulting in distortion of the extracellular matrix (ECM), inflammation, fibrosis and eventual death.

Methods: 13 patients born to consanguineous parents from two unrelated families presenting with interstitial lung disease were clinically investigated.

D-penicillamine-induced pseudo-pseudoxanthoma elasticum and extensive elastosis perforans serpiginosa with excellent response to acitretin.

D-penicillamine (DPA)-induced pseudo-pseudoxanthoma elasticum (PXE) and elastosis perforans serpiginosa (EPS) has been reported in the past, but most of the treatment modalities used before have a sub.optimal response. We report a case of DPA-induced pseudo-PXE with extensive EPS who had an excellent rapid response to acitretin.

Rituximab/IVIG in pemphigus - a 10-year study with a long follow-up.

Background: Pemphigus is a chronic potentially life-threatening autoimmune blistering disease affecting the skin and/or mucous membranes. Rituximab is being increasingly used and found efficacious in the treatment of pemphigus.

Objective: To present the Middle-Eastern experience with the use of rituximab in pemphigus.
