We report a patient with severe psoriasis who failed to respond to phototherapy, conventional systemic treatment and four biologic agents (etanercept, ustekinumab, adalimumab and secukinumab). Combination of a higher-dose secukinumab regimen with phototherapy had no success. Remarkably, ixekizumab, an IL-17A inhibitor, provided almost complete psoriasis clearance after 24 weeks of treatment. The reason for the success of ixekizumab after the failure to respond to a biologic with same mechanism of action is still unknown. Interestingly, failure of secukinumab does not preclude future therapeutic success with a second IL-17A-inhibitor.

Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
