Objective. Despite widespread use of colchicine, the evidence basis for oral colchicine therapy and dosing in acute gout remains limited. The aim of this trial was to compare low-dose colchicine (abbreviated at 1 hour) and high-dose colchicine (prolonged over 6 hours) with placebo in gout flare, using regimens producing comparable maximum plasma concentrations in healthy volunteers.Methods. This multicenter, randomized, doubleblind, placebo-controlled, parallel-group study compared self-administered low-dose colchicine (1.8 mg total over 1 hour) and high-dose colchicine (4.8 mg total over 6 hours) with placebo. The primary end point was >50% pain reduction at 24 hours without rescue medication.Results. There were 184 patients in the intent-totreat analysis. Responders included 28 of 74 patients (37.8%) in the low-dose group, 17 of 52 patients (32.7%) in the high-dose group, and 9 of 58 patients (15.5%) in the placebo group (P ‫؍‬ 0.005 and P ‫؍‬ 0.034, respectively, versus placebo). Rescue medication was taken within the first 24 hours by 23 patients (31.1%) in the low-dose group (P ‫؍‬ 0.027 versus placebo), 18 patients (34.6%) in the high-dose group (P ‫؍‬ 0.103 versus placebo), and 29 patients (50.0%) in the placebo group. The low-dose group had an adverse event (AE) profile similar to that of the placebo group, with an odds ratio (OR) of 1.5 (95% confidence interval [95% CI] 0.7-3.2). High-dose colchicine was associated with significantly more diarrhea, vomiting, and other AEs compared with low-dose colchicine or placebo. With high-dose colchicine, 40 patients (76.9%) had diarrhea (OR 21.3 [95% CI 7.9-56.9]), 10 (19.2%) had severe diarrhea, and 9 (17.3%) had vomiting. With low-dose colchicine, 23.0% of the patients had diarrhea (OR 1.9 [95% CI 0.8-4.8]), none had severe diarrhea, and none had vomiting.Conclusion. Low-dose colchicine yielded both maximum plasma concentration and early gout flare efficacy comparable with that of high-dose colchicine, ClinicalTrials.gov identifier: NCT00506883.

Insulin-like growth factors (IGFs) are essential for local skeletal muscle growth and organismal physiology, but these actions are entwined with glucose homeostasis through convergence with insulin signaling. The objective of this work was to determine whether the effects of IGF-I on growth and metabolism could be separated. We generated muscle-specific IGF-I-deficient (MID) mice that afford inducible deletion of Igf1 at any age. After Igf1 deletion at birth or in young adult mice, evaluations of muscle physiology and glucose homeostasis were performed up to 16 wk of age. MID mice generated at birth had lower muscle and circulating IGF-I, decreased muscle and body mass, and impaired muscle force production. Eight-wk-old male MID had heightened insulin levels with trends of elevated fasting glucose. This phenotype progressed to impaired glucose handling and increased fat deposition without significant muscle mass loss at 16 wk of age. The same phenotype emerged in 16-wk-old MID mice induced at 12 wk of age, compounded with heightened muscle fatigability and exercise intolerance. We assert that muscle IGF-I independently modulates anabolism and metabolism in an age-dependent manner, thus positioning muscle IGF-I maintenance to be critical for both muscle growth and metabolic homeostasis.-Vassilakos, G., Lei, H., Yang, Y., Puglise, J., Matheny, M., Durzynska, J., Ozery, M., Bennett, K., Spradlin, R., Bonanno, H., Park, S., Ahima, R.
