Filter by:Background: Hashimoto's Thyroiditis is an autoimmune disease that attacks thyroid cells through cell- and antibody-mediated immune processes and is characterized by the production of thyroid autoantibodies. In hashimoto, antithyroid peroxidase antibodies are increased and thyroid stimulating hormone levels are elevated. A gluten-free diet regulates thyroid autoimmunization by decreasing the concentration of antibodies. The Mediterranean diet also reduces disease-related oxidative stress parameters in patients with hashimoto's thyroid due to its anti-inflammatory effects. Aims: To evaluate the short-term effects of Mediterranean, gluten-free and Mediterranean gluten-free dietary patterns on thyroid function and autoantibody levels of patients. Study Design: Prospective, single-blind randomized controlled trial including case and control groups Methods: The 40 patients with hashimato thyroiditis included in the study were randomly divided into 4 different groups as gluten-free, Mediterranean, Mediterranean gluten-free and control group for 12 weeks. Thyroid function tests and autoantibody levels were analyzed at the beginning and end of the study. In addition, anthropometric measurements were taken at the beginning and end of the study and food consumption records and food consumption frequencies were evaluated.
The purpose of this study is to explore the relationship between vitamin D and Hashimoto's thyroiditis and to explore whether vitamin D can play an adjuvant role in the treatment of Hashimoto's thyroiditis. Epidemiological surveys show that vitamin D deficiency rates are as high as 50%-90% in HT patients. Dietary supplementation with vitamin D has been evaluated as a way to protect the thyroid gland from autoimmune damage, but the results of randomized clinical trials are unclear.
Autoimmune encephalitis (AE) and paraneoplastic neurological syndromes (PNS) are rare neuroimmune syndromes with a wide range of clinical presentation but without pathognomonic clinical sign facilitating the diagnosis. A lot of differential diagnoses are possible such as neurodegenerative diseases or viral infections. Although rare the diagnosis of AE or PNS is essential because despite severe neurological symptoms, patients can be cured by appropriate immunotherapy. Autoantibodies highly specific of AE and PNS has been described in the serum and cerebrospinal fluid of the patients and can be used as biomarkers of the disease. Their presence can predict an autoimmune origin and in many cases a good prognosis after immunotherapy. However, if some autoantibodies are now well-characterized and industrial kits have been developed to detect them, in numerous cases of highly suspect AE or PNS no specific autoantibodies are identified leading frequently to an inappropriate treatment. Furthermore, as the mechanisms of AE and PNS is still unknown, treatments are not optimal and in some cases inefficient. There is no prognosis biomarker able to predict the patient's sensitivity to immunotherapy and there are only few clues to know how the immune system can provoke the neuropsychiatric symptoms observed in the patients.
Epilepsy is a disorder of the brain in which people have repeated seizures. Autoimmune encephalitis (AE) is a rare cause of epilepsy. It is an inflammatory disease of the brain. This means that the body's own immune system attacks healthy brain tissue, just like it would if it were infected by a virus or a bacteria, by producing an army of proteins called 'antibodies' which go on to 'attack' healthy tissues. Seizures in AE typically do not respond well to classic 'anti-seizure medications'. Instead, medications which suppress the immune system are used. These can have significant side-effects and some patients will still continue to have seizures or experience a recurrence of AE-related epilepsy despite treatment. It is difficult to accurately predict who will experience these outcomes. This study aims to find ways of predicting and monitoring which people with AE are at greatest risk of these outcomes, so we can better direct them towards appropriate treatments. We will collect clinical information and samples of blood and cerebrospinal fluid (CSF, fluid surrounding the brain and spinal cord) from people with AE and 'control' participants with other neurological illnesses. Samples will be analysed for markers which may help predict or correlate with outcomes in AE and better understand this condition.
Hypothyroidism is common, affecting 5% of the general population, for which levothyroxine (LT4) monotherapy is the standard treatment. Despite normalized serum thyroid hormone levels, 10-15% of LT4 treated patients have various persistent complaints, the most important of which is tiredness. This could be explained by the fact that physiological T4/T3 ratios cannot be reached with LT4 monotherapy, as in a healthy individual T3 is not only derived from T4/T3 conversion but is also directly produced by the thyroid itself. Studies have reported contradicting results as to whether addition of liothyronine (LT4/LT3 combination therapy) in patients with persistent tiredness on LT4 monotherapy is effective or not. Studies have suggested higher effectiveness in patients carrying genetic variation in the type 2 deiodinase (DIO2-rs225014) and monocarboxylate transporter 10 (MCT10-rs17606253) genes. Objective: To investigate whether addition of liothyronine (LT4/LT3 combination therapy) in in patients with persistent tiredness on LT4 monotherapy is effective or not in relieving tiredness.
The aim of this study is to compare the thyroid hormone values and anti-thyroid peroxidase (anti-TPO) levels of women with a diagnosis of recurrent pregnancy loss (RPL) and healthy pregnancies. The primary objective is to find out the relationship between recurrent pregnancy loss with thyroid hormone levels and anti-TPO positivity.
The number of acute encephalitides diagnosed each year is gradually increasing, reaching approximately 5 to 10/100,000 per year; more than 50% of etiologies currently remain unknown. The majority of them are acute encephalitis of infectious origin, but it is estimated that 20% of encephalitis in northern Europe is related to an autoimmune mechanism with the majority of encephalitis with anti-NMDA Ac discovered recently in 2007. The study of a large American encephalitis cohort showed a death rate of 3% to 7% in cases of autoimmune encephalitis. Furthermore, delay in the initiation of effective treatment (tumor removal or immunotherapy) beyond 4 weeks is associated with a poor prognosis at 1 year. It is therefore necessary to better understand the signs of autoimmune encephalitis in order to recognize the disease quickly and to start a treatment quickly; in order to improve the management and the prognosis of these children.
Interleukin 2 (IL-2) is a critical cytokine for the survival and function of regulatory T cells (LTreg). This cytokine has a dual role in the immune system. IL-2 stimulates immune responses by acting on the intermediate affinity IL-2R receptor, IL-2Rβγ, expressed by conventional T cells (LTconv) during activation, but also contributes to the inhibition of immune responses via LTreg that express the high affinity receptor IL-2Rαβγ. This difference in IL-2 receptor affinity for IL-2 has led to the development of low-dose IL-2 therapy to stimulate LTreg and improve control of excessive inflammation in autoimmune (AID), inflammatory or alloimmune diseases Low-dose IL-2 therapy is being studied in several of these diseases such as systemic lupus erythematosus, type 1 diabetes, alopecia, HCV (hepatitis C virus)-induced vasculitis, atopic dermatitis and chronic allo-transplantation-related graft-versus-host disease (GVHD). Some of these studies have shown an increase in LTreg numbers and an improvement in certain clinical signs. To improve LTreg targeting in autoimmune diseases, inflammatory diseases or GVHD, mutated IL-2s (muteins) have been developed with selective LTreg agonist properties. These IL-2 muteins are linked to an Fc fragment to increase their half-life. Two IL-2 variants (IL-2Vs)-Fc preferentially stimulate STAT5 phosphorylation in LTregs compared to conventional FoxP3- (LTconv) CD4+ or CD8+ T cells
The purpose of this study is to assess the efficacy, safety, pharmacokinetics, and pharmacodynamics of satralizumab in participants with anti-N-methyl-D-aspartic acid receptor (NMDAR) and anti-leucine-rich glioma-inactivated 1 (LGI1) encephalitis.
This study proposes to randomize patients about to undergo surgery for their autoimmune, inflammatory thyroid disease, and determine if a short course of corticosteroids decreases the inflammation of the gland and makes surgery less difficult.
