Psoriasis and psoriatic arthritis cause significant physical and psychological burdens for afflicted individuals. An accelerated TNF-α/IL-23/IL-17 axis is their major pathomechanism; therefore, anti-TNF-α/IL-23/IL-17 biologics are very effective for the treatment of skin and joint lesions in psoriasis and psoriatic arthritis. Given that the IL-17 signature is more upregulated in the skin than in synovium in psoriatic arthritis, anti-IL-23/IL-17 agents seem to be superior to anti-TNF-α remedies in the treatment of skin lesions. In this review, we focus on the differential efficacy of anti-TNF-α/IL-23/IL-17 biologics in psoriasis and psoriatic arthritis.

Allergic rhinitis (AR) is one of the most common respiratory diseases in children. It is caused by a combination of genetic and environmental factors. Moderate-to-severe AR decreases the quality of life and social performance in children. ⋯ The loci in EMSY and IL4 can be considered as a hereditary marker for childhood AR. The rs7130588_G allele seems to predispose only to moderate-to-severe AR, though other mechanisms are also likely to be involved.

Potential prognostic biomarkers for patients with sepsis have yet to be identified. The present study evaluated the prognostic value of fibroblast growth factor 21 (FGF21) levels in patients with sepsis. ⋯ FGF21 could serve as a new prognostic biomarker for sepsis survival.

Traumatic Brain Injury (TBI) triggers a cascade of secondary biological and physiological effects that are variable, depending on the severity, location, and complexity of the injury. Improved diagnosis and prognosis of brain injury may be possible by examining changes in protein biomarker concentrations and, determining their role in long-term outcomes may improve treatment. One promising direction for biomarker research surrounds pro- and anti-inflammatory cytokines which may have utility for predicting short and long-term prognosis after TBI, and may also be therapeutic targets in shaping neuronal recovery following a TBI. ⋯ Increased levels of interleukin (IL)-6, IL-1, IL-8, IL-10 and tumor necrosis factor alpha (TNFα) were associated with worse outcomes, with most studies focusing on morbidity and mortality. It is important to identify the biochemical changes that may influence or initiate the presentation of health outcomes after a TBI. Earlier identification of symptoms associated with these biochemical changes can be used to support better treatment planning, targeted interventions and ultimately, improvement in patient outcomes.

Gamma delta (γδ) T cells are known to link innate and adaptive immunity. Decidual γδ T cells are known to provide immunotolerance by producing IL-10 and TGF-β. In recurrent pregnancy loss (RPL) females, the role of peripheral γδ T cells remain unstudied. ⋯ Increase in IFN-γ and IL-17-producing CD3+ CD4-CD8- γδ T cells is associated with creating inflammatory cytokine milieu, thereby, may contribute towards pregnancy loss in RPL females.
