CYP-derived eicosanoids: Implications for rheumatoid arthritis

Publication date: Available online 13 December 2019Source: Prostaglandins &Other Lipid MediatorsAuthor(s): Malvina Hoxha, Bruno ZappacostaAbstractToday the role of cytochrome P450 metabolites in inflammatory rheumatic disease, such as rheumatoid arthritis (RA) is still poorly understood. In this review we survey the current knowledge on cytochrome P450 metabolites in rheumatoid arthritis. The balance between CYP epoxygenase- and CYP ω- hydroxylase is correlated to the regulation of NF-κB. In RA patients synovial fluid there are higher levels of IL-6, which suppresses activities of CYP enzymes, such as CYP3A, CYP2C19, CYP2C9, and CYP1A2. EETs have anti-inflammatory effects, probably attributed to the PPARγ activation. EETs inhibit bone resorption and osteoclastogenesis, and can be considered as an innovative therapeutic strategy for rheumatoid arthritis. In reference to the CYP ɷ-hydroxylase pathway, 20-HETE is a pro-inflammatory mediator. While there is scarce information on the role of 20-HETE inhibitors and its antagonists in rheumatoid arthritis, the elevation of EETs levels by sEH inhibitors is a promising therapeutic strategy for rheumatoid arthritis patients. In addition, hybrid compounds, such as sEH inhibitors/FLAP inhibitors, or sEHI combined with NSAIDs/COXIBs are also important therapeutic target.However, studies investigating the effects of inflammation and rheumatic disease on CYP-mediated eicosanoid metabolism are necessary. Obtaining a be...

We report a patient with relapsing-remitting multiple sclerosis, who developed rheumatoid arthritis after exposure to natalizumab. While some multiple sclerosis therapies are known to unmask autoimmune conditions, natalizumab is rarely implicated as a cause of alternative autoimmunity. This case illustrates an unusual clinical scenario which may support recent scientific work suggesting that when natalizumab blocks T helper 1 cells from entering the central nervous system, T helper 17 cells may continue to migrate into immune-privileged spaces and cause pathologic inflammation.Brief Background: Multiple sclerosis (MS) pati...

However, 20-45% of RA patients are TNFi poor responders and have a significantly higher risk of CV events. In these TNFi non-responders, the use of second-line biological agents to improve synovial outcomes is supported by clinical...

Authors: Abuaisha M, El Masri R, Itani H, Antoun J Abstract Objectives: There are no evidence-based recommendations to screen for iron deficiency in non-anemic patients, even though symptoms may be present. The aim of this study is to measure the prevalence of iron deficiency (ID) without anemia in the general population aged 18-50 presenting to primary care along with the incidence and time to develop anemia in the iron-deficient population.Methods: A single-center retrospective chart review of patients who presented to family medicine clinics between June 2010 and March 2018 at the American University of Beirut M...

In this study, we aimed to evaluate the effects of the spirocyclopiperazinium salt compound LXM-15 on rheumatoid arthritis induced by complete Freund ’s adjuvant (CFA) in rats and investigate the underlying mechanism. The results showed that LXM-15 significantly inhibited the paw edema and ankle swelling, and alleviated the mechanical allodynia and thermal hyperalgesia responses in the CFA rats. The histopathological results revealed that LXM-1 5 ameliorated the infiltration of inflammatory cells and joint destruction. The micro-CT scan showed that LXM-15 alleviated bone erosion and increased BMD in the ankle joints ...
