Psoriasis, a chronic immune-mediated skin disorder is associated with significant physical, psychological, and quality of life impairments. Along with well-documented genetic and environmental factors, immunological factors also contribute to the pathogenesis of psoriasis. Among the immunological factors, CD6 - dependent T-cell proliferation to form Th1 and Th17 cells play a major role in the pathogenesis of psoriasis. Itolizumab is the first humanized IgG1 monoclonal antibody, which selectively targets CD6. Areas covered: The current article presents the pharmacology of itolizumab and provides a review of the currently available data on the efficacy and safety of itolizumab for management of moderate to severe plaque psoriasis. Expert opinion: The use of biologics to attenuate the immune-mediated pathological events in psoriasis is a relatively well-established clinical practice. However, the safety and efficacy of biologics continues to be an unsettled topic of ongoing research. While available data seems to suggest that itolizumab may be a safer option, additional studies with higher sample sizes and active comparators are needed before definitive conclusions can be drawn on the place of itolizumab in the management of psoriasis.

Introduction. Levetiracetam (LEV) is a newer antiepileptic drug with better pharmacokinetic profile. Currently, it is frequently used for the treatment of partial seizures. The present study was undertaken to compare the efficacy and safety of LEV and Carbamazepine (CBZ) in partial epilepsy. Methods. This was a prospective, open labeled, randomized study. It was conducted in participants suffering from partial seizures after the approval of ethics committee and written informed consent. The first group received Tab LEV (500 to 3000 mg/day) and the second group received Tab CBZ (300 to 600 mg/day). The primary outcomes were efficacy and safety. The secondary outcome was the Quality of Life (QOL). Efficacy was assessed by comparing the seizure freedom rates at the end of 6 months. Safety profile was evaluated by comparing the adverse effects. QOL was assessed by QOLIE-10 scale. Results. The overall seizure freedom rate at the end of 6 months was 71.42% in CBZ group compared to 78.57% in LEV group (p = 0.2529). Both LEV and CBZ reported a similar incidence of adverse reactions. LEV group reported more behavioral changes like increased aggression and anxiety. Also, it showed better QOL compared to the CBZ group. Conclusion. LEV monotherapy and CBZ monotherapy demonstrated similar efficacy for treatment of partial epilepsy and were found to be well tolerated.

Epilepsy is an important health problem due to its high prevalence and potential for causing long-term morbidity. It is commonly treated in children with phenytoin sodium. It has wide pharmacokinetic variability and a narrow therapeutic range that leads to toxicity. Here, we report a case of phenytoin-induced cerebellar atrophy in a 16-year-old epileptic boy who presented to the hospital with a viral infection.
