    • Does an inflammatory diet promote aging in the brain?


    Celiac.com 09/04/2017 - Researchers think they may have discovered an important connection between diet and dementia.

    For the first time, they have tied a specific dietary pattern to blood markers for inflammation. In addition, they showed that elderly adults who followed a certain dietary pattern had reduced brain gray matter volume, and worse visuospatial cognitive function.

    The team found that “people who consume less omega 3, less calcium, vitamin E, vitamin D, and vitamin B5 and B2 have more inflammatory biomarkers," study investigator Yian Gu, PhD, Columbia University and the Taub Institute for Research on Alzheimer's Disease and the Aging Brain, New York City, told reporters.

    Some studies have linked chronic inflammation to an increased risk for AD. But, until now, no research addressed whether diet affects brain and cognitive health by modulating inflammation.

    "No study has formally tested whether the relationship of diet with cognition, or with the brain, is actually because of inflammation," said Dr Gu.

    Dr. Gu’s research team conducted a new cross-sectional study on 330 elderly adults from the Washington Heights–Inwood Community Aging Project imaging study.

    Researchers conducted structural MRI scans on these patients, and measured levels of the inflammatory biomarkers CRP and IL6. Each participant responded to a 61-item questionnaire about food and nutrient intake over the past year.

    The researchers used the results to craft a statistical model of the inflammation-related nutrient pattern (INP).

    These new findings suggest that dietary and/or medical treatments that reduce inflammatory markers may be helpful.

    Results of their study were presented at the Alzheimer's Association International Conference (AAIC) 2017.

    Celiac.com 01/16/2017 - Cerebellar ataxias can be caused by a wide range of disease processes, either genetic or acquired. Establishing a clear diagnosis requires a methodical approach with expert clinical evaluation and investigation.
    A team of researchers recently published a description of the causes of ataxia in 1500 patients with cerebellar ataxia.  The research team included M Hadjivassiliou, J Martindale, P Shanmugarajah, R A Grünewald, P G Sarrigiannis, N Beauchamp, K Garrard, R Warburton, D S Sanders, D Friend, S Duty, J Taylor, and N Hoggard.
    They are variously affiliated with the Academic Department of Neurosciences, Royal Hallamshire Hospital, Sheffield Teaching Hospitals NHS Trust, Sheffield, UK; Sheffield Diagnostic Genetics Service, Sheffield Children's NHS Foundation Trust, Sheffield, UK; the Department of Gastroenterology, Royal Hallamshire Hospital, Sheffield Teaching Hospitals NHS Trust, Sheffield, UK; and the Department of Neuroradiology, Royal Hallamshire Hospital, Sheffield Teaching Hospitals NHS Trust, Sheffield, UK.
    All patients in the study were referred to the Sheffield Ataxia Centre, UK, and underwent extensive examination, including, where appropriate genetic testing using next-generation sequencing (NGS).
    The team followed-up patients on a 6-month basis for reassessment and further investigations, as needed.
    The team assessed a total of 1500 patients over 20 years. Twenty per cent of those patients had a family history of ataxia, with the remaining having sporadic ataxia.
    The most common cause of sporadic ataxia was gluten ataxia at 25%. They found a genetic cause in 156, or 13% of sporadic cases, with alcohol excess causing 12% and a cerebellar variant of multiple system atrophy causing 11% of sporadic cases.
    Using NGS, they obtained positive results in 32% of 146 patients tested. The most common ataxia they found was EA2. A total of 57% of all familial ataxias were supported by genetic diagnosis. The most common genetic ataxias were Friedreich's ataxia (22%), SCA6 (14%), EA2 (13%), SPG7 (10%) and mitochondrial disease (10%).
    The diagnostic yield following attendance at the Sheffield Ataxia Centre was 63%. Immune-mediated ataxias are common. Advances in genetic testing have significantly improved the diagnostic yield of patients suspected of having a genetic ataxia.
    Making a diagnosis of the cause of ataxia is essential due to potential therapeutic interventions for immune and some genetic ataxias.
    Gluten is a culprit is 25% of sporadic ataxia cases, and clinicians should keep this in mind when diagnosing patients, as many of these cases can be reversed with a gluten-free diet.

    Celiac.com 04/13/2017 - A team of researchers recently set out to determine whether hospital admission for autoimmune disease is associated with an elevated risk of future admission for dementia.
    The research team included Clare J Wotton, and Michael J Goldacre, both affiliated with the Unit of Health-Care Epidemiology, Nuffield Department of Population Health, University of Oxford, Oxford, UK.
    The pair set up their retrospective, record-linkage cohort study using national hospital care and mortality administrative data from 1999–2012. From that patient data, they assembled a study group of people admitted to hospital with a range of autoimmune diseases, along with a control group, and followed forward in time to see if how many patients eventually developed dementia.
    Data revealed a total of 1,833,827 people admitted to hospital with an autoimmune disease. The number of patients for each autoimmune disease group ranged from 1,019 patients in the Goodpasture's syndrome group, to 316,043 people in the rheumatoid arthritis group.
    The researchers found that the rate ratio for dementia after admission for an autoimmune disease, compared with the control cohort, was 1.20 (95% CI 1.19 to 1.21). For patients whose dementia type was specified, the rate ratio ranged from 1.04 to 1.08 for Alzheimer's disease, and 1.26 to 1.31 for vascular dementia.
    Of the 25 autoimmune diseases studied, 18 showed significant positive associations with dementia, 14 of which were statistically significant. Significant associations include Addison's disease (1.48, 1.34 to 1.64), multiple sclerosis (1.97, 1.88 to 2.07), psoriasis (1.29, 1.25 to 1.34) and systemic lupus erythematosus (1.46, 1.32 to 1.61).
    The connections with vascular dementia may be one aspect of a wider connection between autoimmune diseases and vascular damage. Though findings were significant, effect sizes were small. Researchers advise clinicians to note the possibility of dementia in patients with autoimmune disease.
    The researchers are calling for further studies to assess their findings and to explore possible ways to reduce any increased risk.

    Celiac.com 06/12/2017 - Previously, Transcranial Magnetic Stimulation in de novo celiac disease patients has signaled an imbalance in the excitability of cortical facilitatory and inhibitory circuits.
    Researchers have reported that, after about of 16 months on a gluten-free diet, patients experience a global increase of cortical excitability, which suggests some kind of compensation for disease progression, likely mediated by glutamate.
    To better assess these finding, a team of researchers recently conducted cross-sectional evaluation of the changes in cortical excitability to TMS after a much longer gluten-free diet.
    The research team included M. Pennisi, G. Lanza, M. Cantone, R. Ricceri, R. Ferri, C.C. D’Agate, G. Pennisi, V. Di Lazzaro, and R. Bella. They are variously affiliated with the Spinal Unit, Emergency Hospital "Cannizzaro", Catania, Italy, the Department of Neurology IC, I.R.C.C.S. "Oasi Maria SS.", Troina, Enna, Italy, the Department of Medical and Surgical Sciences and Advanced Technologies, Section of Neurosciences, University of Catania, Catania, Italy, the Gastroenterology and Endoscopy Unit, University of Catania, Catania, Italy, the Department "Specialità Medico-Chirurgiche,” University of Catania, Catania, Italy, and the Institute of Neurology, Campus Bio-Medico University, Rome, Italy.
    For their study, the team enrolled twenty patients who had followed an adequate gluten-free diet for about 8.35 years, on average. They then compared the results with twenty de novo patients, and twenty more healthy controls. The team measured Transcranial Magnetic Stimulation, recorded from the first dorsal interosseous muscle of the dominant hand, as follows: resting motor threshold, cortical silent period, motor evoked potentials, central motor conduction time, mean short-latency intracortical inhibition and intracortical facilitation.
    De novo patients showed a shorter cortical silent period, while responses for gluten-free diet participants were similar to controls. Regardless of diet, all celiac patients showed a significantly smaller amplitude of motor response than did control subjects,
    Again, without regard to diet, all celiac patients showed a statistically significant decrease of mean short-latency intracortical inhibition and enhancement of intracortical facilitation with respect to controls.
    The team also observed that gluten-free celiac patients showed more intracortical facilitation compared to non-gluten-free patients. Neurological examination and celiac disease-related antibodies were both negative.
    This study showed that a gluten-free diet helps to mitigate the electrocortical changes associated with celiac disease. Even so, in many patients, an intracortical synaptic dysfunction, mostly involving excitatory and inhibitory interneurons within the motor cortex, may persist.
    The calls for further investigation into the clinical significance of subtle neurophysiological changes in celiac disease.

    Celiac.com 08/10/2017 - Gluten ataxia is defined as sporadic ataxia with positive antigliadin antibodies without an alternative cause. Gluten ataxia patients often receive MRS at baseline and again after a period on a gluten-free diet.
    A research team recently set out to evaluate the effect of gluten free diet on magnetic resonance spectroscopy (MRS) of the cerebellum in patients with gluten ataxia.
    The research team included M Hadjivassiliou, RA Grünewald, DS Sanders, P Shanmugarajah, N Hoggard. They are with the Academic Departments of Neurosciences (M.H., R.A.G., P.S.), Gastroenterology (D.S.S.), and Neuroradiology (N.H.), Sheffield Teaching Hospitals NHS Trust, UK.
    The team included 117 consecutive patients with gluten ataxia in their report. Sixty-three followed a strict a gluten-free diet with elimination of antigliadin antibodies, 35 ate a gluten-free diet, but still tested positive for antigliadin antibodies, while 19 patients were not following a gluten-free diet.
    The N-acetylaspartate (NAA)/creatine (Cr) area ratio from the cerebellar vermis increased in 62 out of 63 (98%) patients on strict a gluten-free diet, in 9 of 35 (26%) patients on a gluten-free diet, but positive antibodies, and in only 1 of 19 (5%) patients not on a gluten-free diet. The NAA/Cr ratio decreased in all 14 ataxia control patients (cerebellar variant of multisystem atrophy), while the researchers saw no differences in the MRS results between patients with celiac disease and those without.
    Better NAA/Cr ratios seen on follow-up scans supports previous findings that gluten ataxia patients see clinical improvement a gluten-free diet
    Such improvements can occur regardless of existing enteropathy, so patients with positive serology and negative duodenal biopsy should still maintain a strict a gluten-free diet.

    Celiac.com 04/23/2018 - A team of researchers recently set out to learn whether celiac disease patients commonly suffer cognitive impairment at the time they are diagnosed, and to compare their cognitive performance with non-celiac subjects with similar chronic symptoms and to a group of healthy control subjects.
    The research team included G Longarini, P Richly, MP Temprano, AF Costa, H Vázquez, ML Moreno, S Niveloni, P López, E Smecuol, R Mazure, A González, E Mauriño, and JC Bai. They are variously associated with the Small Bowel Section, Department of Medicine, Dr. C. Bonorino Udaondo Gastroenterology Hospital; Neurocience Cognitive and Traslational Institute (INECO), Favaloro Fundation, CONICET, Buenos Aires; the Brain Health Center (CESAL), Quilmes, Argentina; the Research Council, MSAL, CABA; and with the Research Institute, School of Medicine, Universidad del Salvador.
    The team enrolled fifty adults with symptoms and indications of celiac disease in a prospective cohort without regard to the final diagnosis.  At baseline, all individuals underwent cognitive functional and psychological evaluation. The team then compared celiac disease patients with subjects without celiac disease, and with healthy controls matched by sex, age, and education.
    Celiac disease patients had similar cognitive performance and anxiety, but no significant differences in depression scores compared with disease controls.
    A total of thirty-three subjects were diagnosed with celiac disease. Compared with the 26 healthy control subjects, the 17 celiac disease subjects, and the 17 disease control subjects, who mostly had irritable bowel syndrome, showed impaired cognitive performance (P=0.02 and P=0.04, respectively), functional impairment (P<0.01), and higher depression (P<0.01). 
    From their data, the team noted that any abnormal cognitive functions they saw in adults with newly diagnosed celiac disease did not seem not to be a result of the disease itself. 
    Their results indicate that cognitive dysfunction in celiac patients could be related to long-term symptoms from chronic disease, in general.

    Celiac.com 04/21/2018 - Dear Friends and Readers,
    I have been writing articles for Scott Adams since the 2002 Summer Issue of the Scott-Free Press. The Scott-Free Press evolved into the Journal of Gluten Sensitivity. I felt honored when Scott asked me ten years ago to contribute to his quarterly journal and it's been a privilege to write articles for his publication ever since.
    Due to personal health reasons and restrictions, I find that I need to retire. My husband and I can no longer travel the country speaking at conferences and to support groups (which we dearly loved to do) nor can I commit to writing more books, articles, or menus. Consequently, I will no longer be contributing articles to the Journal of Gluten Sensitivity. 
    My following books will still be available at Amazon.com:
    Gluten-free Cooking for Dummies Student's Vegetarian Cookbook for Dummies Wheat-free Gluten-free Dessert Cookbook Wheat-free Gluten-free Reduced Calorie Cookbook Wheat-free Gluten-free Cookbook for Kids and Busy Adults (revised version) My first book was published in 1996. My journey since then has been incredible. I have met so many in the celiac community and I feel blessed to be able to call you friends. Many of you have told me that I helped to change your life – let me assure you that your kind words, your phone calls, your thoughtful notes, and your feedback throughout the years have had a vital impact on my life, too. Thank you for all of your support through these years.

    Celiac.com 04/20/2018 - A digital media company and a label data company are teaming up to help major manufacturers target, reach and convert their desired shoppers based on dietary needs, such as gluten-free diet. The deal could bring synergy in emerging markets such as the gluten-free and allergen-free markets, which represent major growth sectors in the global food industry. 
    Under the deal, personalized digital media company Catalina will be joining forces with Label Insight. Catalina uses consumer purchases data to target shoppers on a personal base, while Label Insight works with major companies like Kellogg, Betty Crocker, and Pepsi to provide insight on food label data to government, retailers, manufacturers and app developers.
    "Brands with very specific product benefits, gluten-free for example, require precise targeting to efficiently reach and convert their desired shoppers,” says Todd Morris, President of Catalina's Go-to-Market organization, adding that “Catalina offers the only purchase-based targeting solution with this capability.” 
    Label Insight’s clients include food and beverage giants such as Unilever, Ben & Jerry's, Lipton and Hellman’s. Label Insight technology has helped the Food and Drug Administration (FDA) build the sector’s very first scientifically accurate database of food ingredients, health attributes and claims.
    Morris says the joint partnership will allow Catalina to “enhance our dataset and further increase our ability to target shoppers who are currently buying - or have shown intent to buy - in these emerging categories,” including gluten-free, allergen-free, and other free-from foods.
    The deal will likely make for easier, more precise targeting of goods to consumers, and thus provide benefits for manufacturers and retailers looking to better serve their retail food customers, especially in specialty areas like gluten-free and allergen-free foods.

    Celiac.com 04/19/2018 - Previous genome and linkage studies indicate the existence of a new disease triggering mechanism that involves amino acid metabolism and nutrient sensing signaling pathways. In an effort to determine if amino acids might play a role in the development of celiac disease, a team of researchers recently set out to investigate if plasma amino acid levels differed among children with celiac disease compared with a control group.
     
    The research team included Åsa Torinsson Naluai, Ladan Saadat Vafa, Audur H. Gudjonsdottir, Henrik Arnell, Lars Browaldh, and Daniel Agardh. They are variously affiliated with the Institute of Biomedicine, Department of Microbiology & Immunology, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden; the Institute of Clinical Sciences, Sahlgrenska Academy at the University of Gothenburg, Gothenburg, Sweden; the Department of Pediatric Gastroenterology, Hepatology and Nutrition, Karolinska University Hospital and Division of Pediatrics, CLINTEC, Karolinska Institute, Stockholm, Sweden; the Department of Clinical Science and Education, Karolinska Institute, Sodersjukhuset, Stockholm, Sweden; the Department of Mathematical Sciences, Chalmers University of Technology, Gothenburg, Sweden; the Diabetes & Celiac Disease Unit, Department of Clinical Sciences, Lund University, Malmö, Sweden; and with the Nathan S Kline Institute in the U.S.A.
    First, the team used liquid chromatography-tandem mass spectrometry (LC/MS) to analyze amino acid levels in fasting plasma samples from 141 children with celiac disease and 129 non-celiac disease controls. They then crafted a general linear model using age and experimental effects as covariates to compare amino acid levels between children with celiac disease and non-celiac control subjects.
    Compared with the control group, seven out of twenty-three children with celiac disease showed elevated levels of the the following amino acids: tryptophan; taurine; glutamic acid; proline; ornithine; alanine; and methionine.
    The significance of the individual amino acids do not survive multiple correction, however, multivariate analyses of the amino acid profile showed significantly altered amino acid levels in children with celiac disease overall and after correction for age, sex and experimental effects.
    This study shows that amino acids can influence inflammation and may play a role in the development of celiac disease.

    Celiac.com 04/18/2018 - To the relief of many bewildered passengers and crew, no more comfort turkeys, geese, possums or other questionable pets will be flying on Delta or United without meeting the airlines' strict new requirements for service animals.
    If you’ve flown anywhere lately, you may have seen them. People flying with their designated “emotional support” animals. We’re not talking genuine service animals, like seeing eye dogs, or hearing ear dogs, or even the Belgian Malinois that alerts its owner when there is gluten in food that may trigger her celiac disease.
    Now, to be honest, some of those animals in question do perform a genuine service for those who need emotional support dogs, like veterans with PTSD.
    However, many of these animals are not service animals at all. Many of these animals perform no actual service to their owners, and are nothing more than thinly disguised pets. Many lack proper training, and some have caused serious problems for the airlines and for other passengers.
    Now the major airlines are taking note and introducing stringent requirements for service animals.
    Delta was the first to strike. As reported by the New York Times on January 19: “Effective March 1, Delta, the second largest US airline by passenger traffic, said it will require passengers seeking to fly with pets to present additional documents outlining the passenger’s need for the animal and proof of its training and vaccinations, 48 hours prior to the flight.… This comes in response to what the carrier said was a 150 percent increase in service and support animals — pets, often dogs, that accompany people with disabilities — carried onboard since 2015.… Delta said that it flies some 700 service animals a day. Among them, customers have attempted to fly with comfort turkeys, gliding possums, snakes, spiders, and other unusual pets.”
    Fresh from an unsavory incident with an “emotional support” peacock incident, United Airlines has followed Delta’s lead and set stricter rules for emotional support animals. United’s rules also took effect March 1, 2018.
    So, to the relief of many bewildered passengers and crew, no more comfort turkeys, geese, possums or other questionable pets will be flying on Delta or United without meeting the airlines' strict new requirements for service and emotional support animals.
