In summary, the authors have omitted critical detailsof the case, made unsupported extrapolations,failed to appropriately review the scientific literature, and arrived at conclusions that lack scientific supportor merit. Contrary to their assertions, there is littlethat is similar between p-synephrine and ephedrinewith respect to pharmacokinetic properties, adrenergicreceptor binding, and pharmacological and toxicologicaleffects.

Rheumatoid arthritis (RA) is an autoimmune, chronic systemic inflammatory disorder. The long-term use of currently available drugs for the treatment of RA has many potential side effects. Natural phytonutrients may serve as alternative strategies for the safe and effective treatment of RA, and curcuminoids have been used in Ayurvedic medicine for the treatment of inflammatory conditions for centuries. In this study, a novel, highly bioavailable form of curcumin in a completely natural turmeric matrix was evaluated for its ability to improve the clinical symptoms of RA. A randomized, double-blind, placebo-controlled, three-arm, parallel-group study was conducted to evaluate the comparative efficacy of two different doses of curcumin with that of a placebo in active RA patients. Twelve patients in each group received placebo, 250 or 500 mg of the curcumin product twice daily for 90 days. The responses of the patients were assessed using the American College of Rheumatology (ACR) response, visual analog scale (VAS), C-reactive protein (CRP), Disease Activity Score 28 (DAS28), erythrocyte sedimentation rate (ESR), and rheumatoid factor (RF) values. RA patients who received the curcumin product at both low and high doses reported statistically significant changes in their clinical symptoms at the end of the study. These observations were confirmed by significant changes in ESR, CPR, and RF values in patients receiving the study product compared to baseline and placebo. The results indicate that this novel curcumin in a turmeric matrix acts as an analgesic and anti-inflammatory agent for the management of RA at a dose as low as 250 mg twice daily as evidenced by significant improvement in the ESR, CRP, VAS, RF, DAS28, and ACR responses compared to placebo. Both doses of the study product were well tolerated and without side effects.

Circulatory markers of low-grade inflammation such as tumor necrosis factor-alpha (TNF-α), interleukin-1 alpha (IL-1α), and interleukin-1 beta (IL-1β) positively correlate with endothelial damage, atheroma formation, cardiovascular disease, and aging. The natural vitamin K2-menaquinone-7 (MK-7) added to the cell culture of human monocyte-derived macrophages (hMDMs) at the same time as toll-like receptor (TLR) agonists did not influence the production of TNF-α. When the cells were pretreated up to 6 h with MK-7 before treatment with TLR agonists, MK-7 did not inhibit significantly the production of TNF-α after the TLR activation. However, 30 h pretreatment of hMDMs with at least 10 μM of MK-7 effectively and dose dependently inhibited the proinflammatory function of hMDMs. Pretreatment of hMDMs with 10 μM of MK-7 for 30 h resulted in 20% inhibition of TNF-α production after lipopolysaccharide (LPS) activation (P < .05) and 43% inhibition after macrophage-activating lipopeptide (MALP) activation (P < .001). Pathogen-associated molecular pattern (PMPP) activation was inhibited by 20% with MK-7 pretreatment; however, this inhibition was not statistically significant. The 30 h pretreatment of a THP-1-differentiated monocyte cell line with MK-7 resulted in a dose-dependent downregulation of TNFα, IL-1α, and IL-1β gene expression as evaluated by RNA semiquantitative reverse transcription polymerase chain reaction (RT-PCR). MK-7 is able to modulate immune and inflammatory reactions in the dose–response inhibition of TNF-α, IL-1α, and IL-1β gene expression and protein production by the healthy hMDMs in vitro.
