Increased xanthine oxidase-related ROS production and TRPV1 synthesis preceding DOMS post-eccentric exercise in rats.
    Life sciences, 2016, May-01, Volume: 152

    It is well-known that unaccustomed exercise, especially eccentric exercise, is associated to delayed onset muscle soreness (DOMS). Whether DOMS is associated with reactive oxygen species (ROS) and the transient receptor potential vanilloid 1 (TRPV1) is still an open question. Thus, the aim of this study was to investigate the association between TRPV1 and xanthine oxidase-related ROS production in muscle and DOMS after a bout of eccentric exercise.. Male Wistar rats performed a downhill running exercise on a treadmill at a -16° tilt and a constant speed for 90min (5min/bout separated by 2min of rest). Mechanical allodynia and grip force tests were performed before and 1, 3, 6, 9, 12, 24, 48 and 72h after the downhill running. Biochemical assays probing oxidative stress, purine degradation, xanthine oxidase activity, Ca(2+) ATPase activity and TRPV1 protein content were performed in gastrocnemius muscle at 12, 24, and 48h after the downhill running.. Our statistical analysis showed an increase in mechanical allodynia and a loss of strength after the downhill running. Similarly, an increase in carbonyl, xanthine oxidase activity, uric acid levels and TRPV1 immunoreactivity were found 12h post-exercise. On the other hand, Ca(2+) ATPase activity decreased in all analyzed times.. Our results suggest that a possible relationship between xanthine oxidase-related ROS and TRPV1 may exist during the events preceding eccentric exercise-related DOMS.

Inhibition of xanthine oxidase to prevent statin-induced myalgia and rhabdomiolysis.
    Atherosclerosis, 2015, Volume: 239, Issue:1

    Although statins remain the cornerstone of lipid-lowering therapy for reducing the burden of atherosclerotic vascular disease, their administration has been associated with muscle-related adverse effects, including myalgia and rhabdomyolysis. Such adverse events are probably due to reduced antioxidant defenses associated with fewer intermediate metabolites in the cholesterol synthesis pathway. We hypothesize that the concomitant inhibition of xanthine oxidase via coadministration of allopurinol with statins could diminish reactive oxygen species (ROS)-related muscle damage, which would have in turn have positive effects on both the incidence of muscle-related adverse events and cardiovascular outcomes. Accordingly, inhibition of xanthine oxidase has been previously shown to be effective for reducing biomarkers of muscle damage following exercise in professional athletes. Because of the widespread statin utilization and increasing trends in their therapeutic use in atherosclerotic vascular diseases, the proposed strategy could have important clinical implications for reducing statin-induced myalgia and rhabdomyolysis.

[CHRONIC MYELOID LEUKEMIA IN A YOUNG MALE PRESENTING WITH BILATERAL CALF PAIN DUE TO LEUKOSTASIS].
    Harefuah, 2015, Volume: 154, Issue:5

    Chronic myeloid Leukemia (CML) is a chronic myeloproliferative disorder, caused by the unregulated proliferation of granulocytes at different stages of development and maturation. Leukostasis is one of the complications of CML, causing partial or total occlusion of microvasculature with a variety of clinical manifestations, mostly ophthalmic, neurologic or respiratory. Recently, we encountered a 21-year old soldier, who complained of severe bilateral calf pain which began a few months earlier during training. He underwent complete ambulatory orthopedic evaluation which was unrevealing, and finally presented to the hospital casualty department where CML was diagnosed on the basis of an elevated WBC count and morphologic findings. Bilateral retinal hemorrhages due to leukostasis were noticed at fundoscopy. The calf pain resolved completely after leukapheresis and initial cytoreductive therapy and was in retrospect attributed to peripheral leukostasis. To the best of our knowledge this is the first report of CML presenting with bilateral calf pain due to Leukocytosis and possible leukostasis. This case report highlights the importance of differential diagnosis in cases of calf pain and the awareness of this rare manifestation of CML.
