Effect of ancient Khorasan wheat on gut microbiota, inflammation, and short-chain fatty acid production in patients with fibromyalgia.

BACKGROUND: Fibromyalgia (FM) syndrome is mainly characterized by widespread pain, sleeping disorders, fatigue, and cognitive dysfunction. In many cases, gastrointestinal distress is also reported, suggesting the potential pathogenic role of the gut microbiota (GM). The GM is deeply influenced by several environmental factors, especially the diet, and recent findings highlighted significant symptom improvement in FM patients following various nutritional interventions such as vegetarian diet, low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols based diets, gluten-free diet, and especially an ancient grain supplementation. In particular, a recent study reported that a replacement diet with ancient Khorasan wheat led to an overall improvement in symptom severity of FM patients. AIM: To examine the effects of ancient Khorasan wheat on the GM, inflammation, and short-chain fatty acid production in FM patients. METHODS: After a 2-wk run-in period, 20 FM patients were enrolled in this randomized, double-blind crossover trial. In detail, they were assigned to consume either Khorasan or control wheat products for 8 wk and then, following an 8-wk washout period, crossed. Before and after treatments, GM characterization was performed by 16S rRNA sequencing while the fecal molecular inflammatory response and the short-chain fatty acids (SCFAs) were respectively determined with the Luminex MAGPIX detection system and a mass chromatography-mass spectrometry method. RESULTS: The Khorasan wheat replacement diet, in comparison with the control wheat diet, had more positive effects on intestinal microbiota composition and on both the fecal immune and SCFAs profiles such as the significant increase of butyric acid levels (P = 0.054), candidatus Saccharibacteria (P = 9.95e-06) and Actinobacteria, and the reduction of Enterococcaceae (P = 4.97e-04). Moreover, the improvement of various FM symptoms along with the variation of some gut bacteria after the Khorasan wheat diet have been documented; in fact we reported positive correlations between Actinobacteria and both Tiredness Symptoms Scale (P < 0.001) and Functional Outcome of Sleep Questionnaire (P < 0.05) scores, between Verrucomicrobiae and both Widespread Pain Index (WPI) + Symptom Severity scale (SS) (P < 0.05) and WPI (P < 0.05) scores, between candidatus Saccharibacteria and SS score (P < 0.05), and between Bacteroidales and Sleep-Related and Safety Behaviour Questionnaire score (P < 0.05). CONCLUSION: The replacement diet based on ancient Khorasan wheat results in beneficial GM compositional and functional modifications that positively correlate with an improvement of FM symptomatology.

Applications of Ketogenic Diets in Patients with Headache: Clinical Recommendations.

Headaches are among the most prevalent and disabling neurologic disorders and there are several unmet needs as current pharmacological options are inadequate in treating patients with chronic headache, and a growing interest focuses on nutritional approaches as non-pharmacological treatments. Among these, the largest body of evidence supports the use of the ketogenic diet (KD). Exactly 100 years ago, KD was first used to treat drug-resistant epilepsy, but subsequent applications of this diet also involved other neurological disorders. Evidence of KD effectiveness in migraine emerged in 1928, but in the last several year's different groups of researchers and clinicians began utilizing this therapeutic option to treat patients with drug-resistant migraine, cluster headache, and/or headache comorbid with metabolic syndrome. Here we describe the existing evidence supporting the potential benefits of KDs in the management of headaches, explore the potential mechanisms of action involved in the efficacy in-depth, and synthesize results of working meetings of an Italian panel of experts on this topic. The aim of the working group was to create a clinical recommendation on indications and optimal clinical practice to treat patients with headaches using KDs. The results we present here are designed to advance the knowledge and application of KDs in the treatment of headaches.

Effectiveness of a Khorasan Wheat-Based Replacement on Pain Symptoms and Quality of Life in Patients with Fibromyalgia.

OBJECTIVE: To investigate the effects of a replacement diet with Khorasan wheat products in patients with fibromyalgia, in comparison with a similar replacement diet with control products made from organic semi-whole-grain modern wheat. DESIGN: Randomized, double-blinded crossover trial. SETTING: Outpatient clinic. SUBJECTS: Twenty subjects (19 female and one male, mean age = 48.9 ± 12.3 years) with fibromyalgia. METHODS: Participants were randomly assigned to consume either Khorasan or control wheat products (pasta, bread, crackers, biscuits) for eight weeks and then crossed. Validated self-administered questionnaires were collected from each subject at the beginning and end of each intervention period. RESULTS: A general linear model for repeated measurement, adjusted for potential confounders, showed that the overall score reported from each questionnaire improved after both intervention and control periods, but the effect was more evident after the intervention with Khorasan. In particular, a statistically significant difference in Widespread Pain Index (WPI) + Severity Scale (SS) and Functional Outcome of Sleep Questionnaire (FOSQ) was observed, which decreased significantly by 21.5% and 11.7% respectively, only after the Khorasan period, while no statistically significant variations were reported after the control period. Similarly, FM Impact Questionnaire scores decreased significantly only after the Khorasan period, with a reduction that was significantly different between the intervention and control periods (-22.5% vs -0.3%, P = 0.037). The improvement was even greater in people with higher symptom severity. CONCLUSIONS: A dietary intervention with Khorasan wheat products seems to benefit patients with fibromyalgia, especially those with greater symptom severity.

Use of opioids for treatment of osteoporotic pain.

The prevalence of osteoporosis increases markedly with age: currently it is estimated that over 200 million people suffer from osteoporosis worldwide. One of the most feared and more frequent complications of osteoporosis is pain, which affects 85% of patients. Commonly in the treatment of chronic pain the therapeutic strategy is based on a three-ladder approach, involving opioids for moderate and severe pain. As proposed by the World Health Organization (WHO), according to the intensity of chronic pain, analgesic treatment can be established. Despite the debate and updates to the analgesic ladder for pain published in 1986 by the WHO, the benefits resulting from its worldwide use are uncontested. In case the pain was not responsive to drugs of pain ladder, is necessary to resort to specialized practices (e.g. subarachnoid infusion of drugs). The oral route for administering analgesics should be preferred, provided that the patients are able to use it. About 50% of all opioid users experience at least one side effect, and more than 20% discontinued treatment due to a serious adverse event. Despite published guidelines and WHO's pain ladder for the management of chronic pain, the treatment of this condition remains suboptimal. Given the physiopsychopathology and complexity of the problems of chronic osteoporotic pain, a multimodal and multidisciplinary approach is still considered the best way to diagnose and treat this disease.
