Psoriasis is a systemic chronic skin disorder characterized by excessive keratinocytes proliferation that results into thickened scaly plaques, itching and inflammatory changes in the epidermis and dermis. It is transmitted genetically but can be provoked by environmental factors.
It is found in approximately 2% of the population that primarily affects the skin and joints.
It is associated with other inflammatory disorders and autoimmune diseases (eg psoriatic arthritis, inflammatory bowel disease, coronary artery disease).
Generally, it begins as red scaling papules that coalesce to form round-to-oval plaques. The rashes are often pruritic and may be painful.
Treatment with tumour necrosis factor-alpha (TNFα) inhibitor may likely lead to an increase in body weight and body mass index (BMI) in patients with psoriasis, whereas treatment with anti-interleukin (IL)-12/23 and IL-17 biologics does not, results of a recent systematic review and meta-analysis have shown.
Biologic therapies for psoriasis may need to be switched between classes to increase drug survival in patients, suggest a recent study. Ad hoc retrospective studies are needed to confirm the benefits of this switching strategy.
The first-in-class interleukin (IL)-17A monoclonal antibody secukinumab is a safe and effective treatment for moderate-to-severe plaque psoriasis, with efficacy rates similar to those found in its phase III studies and enduring up to a year from start of treatment.
The risk of serious infection* among patients receiving systemic therapy for psoriasis differs by treatment, with apremilast, etanercept, and ustekinumab associated with a reduced risk of serious infection than methotrexate, according to an observational study.
New drug applications approved by US FDA as of 16 - 30 April 2019 which includes New Molecular Entities (NMEs) and new biologics. It
does not include Tentative Approvals. Supplemental approvals may have
occurred since the original approval date.
Psoriasis appears to be a risk factor for mortality from all causes in a dose-response manner with disease severity and from several specific causes, suggest the results of a systematic review and meta-analysis.
The fully human monoclonal antibody secukinumab triumphed over ustekinumab once again in patients with moderate-to-severe plaque psoriasis, according to the phase IIIb CLARITY* trial presented at the recent annual meeting of the American Academy of Dermatology (AAD 2019).
Adding the neuraminidase inhibitor oseltamivir to usual care speeds up recovery from influenza-like illness by a day compared with usual care alone, with even greater benefits seen in older, sicker patients with comorbidities, according to the ALIC4E study.
Anaemia increases mortality risk in heart failure (HF) patients across the ejection fraction (EF) spectrum, a recent study has found. The effect appears to be stronger in preserved (HFpEF) and midrange (HFmrEF) than in reduced (HFrEF) EF disease.
