IntroductionThe medicinal treatment of osteoarthritis (OA) is mostly symptomatic to relieve pain and incapacity with analgesics and non-steroidal anti-inflammatory drugs (NSAIDs), drugs with well-known risks. Complementary medicines might reduce the symptoms of OA and decrease the need for NSAIDs. This study tested the effects of a food supplement, Phytalgic®, on pain and function in patients with osteoarthritis and their use of analgesic and NSAIDs.MethodsA randomized double-blind parallel-groups clinical trial compared Phytalgic® (fish-oil, vitamin E, Urtica dioica) to a placebo for three months, in 81 patients with OA of the knee or hip using NSAIDs and/or analgesics regularly. The main outcome measures were use of NSAIDs (in Defined Daily Doses per day - DDD/day) or analgesics (in 500 mg paracetamol-equivalent tablets per week (PET/week) measured each month, and Western Ontario-McMaster University Osteo-Arthritis Index (WOMAC) function scales.ResultsAfter three months of treatment, the mean use of analgesics in the active arm (6.5 PET/week) vs. the placebo arm (16.5) was significantly different (P < 0.001) with a group mean difference of -10.0 (95% CI: -4.9 to -15.1). That of NSAIDs in the active arm (0.4 DDD/day) vs the placebo arm (1.0 DDD/day) was significantly different (P = 0.02) with a group mean difference of - 0.7 DDD/day (95% CI: -0.2 to -1.2). Mean WOMAC scores for pain, stiffness and function in the active arm (respectively 86.5, 41.4 and 301.6) vs the placebo arm (resp. 235.3, 96.3 and 746.5) were significantly different (P < 0.001) with group mean differences respectively of -148.8 (95% CI: -97.7 to -199.9), -54.9 (95% CI: -27.9 to -81.9) and -444.8 (95% CI: -269.1 to -620.4).ConclusionsThe food supplement tested appeared to decrease the need for analgesics and NSAIDs and improve the symptoms of osteoarthritis.Trial registrationClinicaltrials.gov NCT00666523.

Aims Pictograms on medicine boxes warn of potential drug‐related driving hazard; we studied their association with serious accidents. Methods Prospective study in emergency departments of the hospitals in Bordeaux and Périgueux (France), of drivers with serious (admitted at least 24 hours) or nonserious vehicular accidents. Minors, passengers, pedestrians or subjects incapable of answering an interview were excluded. Interviews ascertained driver and accident characteristics, use of drugs with or without pictograms, use of alcohol and abuse substances, sleepiness, distractions, and mind wandering at the time of the accident, Results Between 18 October 2016 and 26 December 2018, 1200 of the 6212 drivers admitted to the hospital emergency rooms, 741 nonserious, 459 serious, were interviewed. Serious accidents were associated with male sex (odds ratio 1.89, 95% confidence interval [1.36–2.64]), age above 60 years (3.64 [2.21–6.00]), driving on local roads (3.34 [2.34–4.76]), driving a motorcycle (3.39 [2.29–5.00]), having drunk alcohol within 6 hours (2.89 [1.85–4.51]) and using a drug with a pictogram during the 24 hours previous to the accident (1.57 [1.06–2.32]). From 207 police reports, 101 drivers were not responsible, and 106 were responsible, associated with age below 40 years, driving in overcast or rainy weather (2.62 [1.29–5.33]), on local roads (3.89 [1.90–7.95]), and use of at least 1 pictogram drug in the previous week (3.12 [1.31–7.41]). Conclusion The known risks of alcohol and pictogram drugs, of riding motorcycles and using local roads were confirmed. As measured, behavioural sleepiness did not predict accidents.

To investigate the effect of chronic oral arginine aspartate on the growth hormone (GH), GH-releasing hormone (GHRH), insulin-like growth factor-1 (IGF-1) and IGF-binding protein-3 (IGFBP-3) secretions in healthy volunteers. Twenty-three healthy non-athlete volunteer males were administered arginine aspartate (30 g) orally once daily at 21:00 h for 21 consecutive days. Subjects were hospitalized on days 0, 1, 3, 5, 7, 14 and 21 of treatment. At each hospitalization, concentrations of GHRH, GH, IGF-1 and IGFBP-3 were measured over 4 h after arginine aspartate intake. GH, IGF-1 and IGFBP-3 concentrations were also determined over 12 h at days 0, 1 and 21. Compared with day 1, 4 h GH levels dropped at day 5 and subsequently rose to levels not significantly different from initial ones. The latter was substantiated by 12 h GH levels that did not significantly change from days 1 to 21. GHRH levels were not statistically different, although there was a trend in median values that seemed to inversely mirror those of GH. This dynamic over the course of the study for GH and GHRH was accompanied by a general decrease in IGF-1 and IGFBP-3. In healthy volunteers, a chronic oral treatment with 30 g/day arginine aspartate is followed by a decrease in IGF-1 and IGFBP-3 secretions.
