Inflammatory Autoimmune Disease

: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease, which involves a pathological inflammatory response against articular cartilage in multiple joints throughout the body. It is a complex disorder associated with comorbidities such as depression, lymphoma, osteoporosis and cardiovascular disease (CVD), which significantly deteriorate patients’ quality of life and prognosis. This has ignited a large initiative to elucidate the physiopathology of RA, aiming to identify new therapeutic targets and approaches in its multidisciplinary management. Recently, various lipid bioactive products have been proposed to have an essential role in this process; including eicosanoids, specialized pro-resolving mediators, phospholipids/sphingolipids, and endocannabinoids. Dietary interventions using omega-3 polyunsaturated fatty acids or treatment with synthetic endocannabinoids agonists have been shown to significantly ameliorate RA symptoms. Indeed, the modulation of lipid metabolism may be crucial in the pathophysiology and treatment of autoimmune diseases.

Inflammatory Autoimmune Disease

: Post Translational Modification (PTM) is the process in which covalent addition of functional groups on protein happens to maintain their structure, function and stability. Every PTM process in our living system happens to increase the functional diversity of protein. But sometimes it happens without any regulation and occurrence of this specific change in proteins are leading to autoimmunity. Rheumatoid arthritis (RA) is one such chronic, inflammatory, autoimmune disease that affects joints. Proper treatment can be manageable for RA, but it is not completely curable. Delayed diagnosis of RA can cause severe bone pain, stiffness, inflammation, redness in joints and affect other parts of the body such as liver, kidney etc. Early diagnosis of disease is preferable to cure it effectively. Currently, Rheumatoid factor (RF) and anti-citrullinated cyclic peptide (Anti-CCP) are considered as biomarkers to diagnose RA. Other than citrullination several other PTM’s are also involved in generation of autoantibodies such as, carbamylation, glycosylation, glycation, acetylation, ubiquitination, proteolysis, phosphorylation, lipidation. Aim of this review is to elucidate several considerable changes in form, nature and function of above PTMs in RA, affecting joints and day to day life. This review will give a recent overview on the role of PTMs in the pathogenesis of RA, focusing on the modifications.

Sedentary Life Style

We are in technical era where there is more of sedentary life style and stress along with this urbanization is affecting our quality of food and health. This is leading to many lifestyle disorders and hormonal imbalances in our body. Hypothyroidism one among the endocrinal disorder. Thyroid is an endocrinal gland secrets T3 and T4 hormones regulated by TSH which is secreted by Pituitary gland. These hormones have two major effects on the body, 1) To increase the overall metabolic rate in the body 2) To stimulate growth in children. Hypothyroidism is common health issue in India. The highest prevalence of hypothyroidism (13.1%) is noted in people aged 46-54yrs old. With people aged 18-35 yrs being less affected (7.5%). To prevent these hazards Panchakarma is beneficiary to maintain metabolic rate. Here an attempt is made to diagnose hypothyroidism in the light of Ayurveda and management guidelines through Panchakarma.

Inflammatory Autoimmune Disease

Rheumatoid arthritis (RA) is a highly debilitating chronic inflammatory autoimmune disease most prevalent in women. The true etiology of this disease is complex, multifactorial, and is yet to be completely elucidated. However, oxidative stress and lipid peroxidation are associated with the development and pathogenesis of RA. In this case, oxidative damage biomarkers have been found to be significantly higher in RA patients, associated with the oxidation of biomolecules and the stimulation of inflammatory responses. Lipid peroxidation is one of the major consequences of oxidative stress, with the formation of deleterious lipid hydroperoxides and electrophilic reactive lipid species. Additionally, changes in the lipoprotein profile seem to be common in RA, contributing to cardiovascular diseases and a chronic inflammatory environment. Nevertheless, changes in the lipid profile at a molecular level in RA are still poorly understood. Therefore, the goal of this review was to gather all the information regarding lipid alterations in RA analyzed by mass spectrometry. Studies on the variation of lipid profile in RA using lipidomics showed that fatty acid and phospholipid metabolisms, especially in phosphatidylcholine and phosphatidylethanolamine, are affected in this disease. These promising results could lead to the discovery of new diagnostic lipid biomarkers for early diagnosis of RA and targets for personalized medicine.

Background:Interstitial lung disease (ILD) is one of the most significant comorbidities of rheumatoid arthritis (RA), increasing the mortality in these patients [1,2]. Although the pathogenesis of ILD associated to RA (RA-ILD+) remains poorly defined [1], it is known that vascular tissue plays a crucial role in lung physiology [3]. In this context, a population of cells termed endothelial progenitor cells (EPC) are involved in vasculogenesis and endothelial tissue repair [4]. Previous reports suggest the implication of EPC in different conditions such as RA and idiopathic pulmonary fibrosis (IPF), the most common and destructive ILD [5,6]. Nevertheless, little is known about their specific role in RA-ILD+.Objectives:The purpose of this study was to shed light on the potential role of EPC in endothelial damage in RA-ILD+.Methods:Peripheral venous blood was collected from a total of 68 individuals (18 with RA-ILD+, 17 with RA-ILD-, 19 with IPF and 14 healthy controls). All subjects were recruited from the Rheumatology and Pneumology departments of Hospital Universitario Marqués de Valdecilla, Santander, Spain. Quantification of EPC was analyzed by the expression of surface antigens by flow cytometry. The combination of antibodies against the stem cell marker CD34, the immature progenitor marker CD133, the endothelial marker VEGF receptor 2 (CD309) and the common leukocyte antigen CD45 was used. EPC were considered as CD34+, CD45Low, CD309+and CD133+. All statistical analyses were performed using Prism software 5 (GraphPad).Results:EPC frequency was significantly increased in patients with RA-ILD+, RA-ILD-and IPF compared to controls (p=0.001, p=0.002, p< 0.0001, respectively). Nevertheless, patients with RA, both RA-ILD+and RA-ILD-, showed a lower frequency of EPC than those with IPF (p= 0.048, p= 0.006, respectively).Conclusion:Our results provide evidence for a potential role of EPC as a reparative compensatory mechanism related to endothelial damage in RA-ILD+, RA-ILD-and IPF patients. Interestingly, EPC frequency may help to establish a differential diagnostic between patients with IPF and those who have an underlying autoimmune disease (RA-ILD+).References:[1] J Clin Med 2019; 8: 2038;[2] Arthritis Rheumatol 2015; 67: 28-38;[3] Nat Protoc 2015; 10: 1697-1708;[4] Science 1997; 275: 964-966;[5] Rheumatology (Oxford) 2012; 51: 1775-1784;[6] Angiogenesis 2013; 16: 147-157.Acknowledgments:Personal funds, VP-C: PREVAL18/01 (IDIVAL); SR-M: RD16/0012/0009 (ISCIII-ERDF); LL-G: PI18/00042 (ISCIII-ERDF); RL-M: Miguel Servet type I CP16/00033 (ISCIII-ESF).Disclosure of Interests:Verónica Pulito-Cueto: None declared, Sara Remuzgo-Martínez: None declared, Fernanda Genre: None declared, Victor Manuel Mora-Cuesta: None declared, David Iturbe Fernández: None declared, Sonia Fernández-Rozas: None declared, Leticia Lera-Gómez: None declared, Pilar Alonso Lecue: None declared, Javier Rodriguez Carrio: None declared, Belén Atienza-Mateo: None declared, Virginia Portilla: None declared, David Merino: None declared, Ricardo Blanco Grant/research support from: AbbVie, MSD, Roche, Consultant of: Abbvie, Eli Lilly, Pfizer, Roche, Bristol-Myers, Janssen, UCB Pharma and MSD, Speakers bureau: Abbvie, Eli Lilly, Pfizer, Roche, Bristol-Myers, Janssen, UCB Pharma.

The Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) is an infectious disease caused by coronavirus disease 2019 (COVID-19) and has affected people's lives globally, since first case was detected in Wuhan, China in December 2019. The coronavirus pandemic has turned the world’s attention to the immune system, the body’s defense mechanism against disease. Concept of Ojas is well explained in all ayurvedic classics, in modern perspective it is considered as immunity (Vyadhikshamatava). Ojas is necessary for well-being of the body, and mind. In Ayurveda textbook, the epidemics and along with their management are discussed under the term of Janapadodhvansa. The preventive and curative treatments for communicable diseases of the Janapadodhvansa (epidemics) are Panchkarma (five bio-purification therapies), Rasayana Chikitsa (rejuvenation treatment), Achara Rasayana (good conducts), and migrate to the place, free from communicable diseases. The intake of all types Rasayanas leads to increase of Ojas and reduce all psychological (mainly stress and emotional) disorder, thereby causes increase immunity responses and help to fight against covid-19. Key Words: Ayurveda, Covid-19, Immunity, Janapadodhvansa, Ojas, Rasayana Chikitsa.

Background: Rheumatoid arthritis (RA) is a inflammatory disease that characterized with the destruction of synovial joint, which could induce disability. Inflammatory response mediated the RA. It has been reported that MiR-128-3p is significantly increased in RA, while the potential role was still unclear. Methods: T cells in peripheral blood mononuclear cell (PBMC) were isolated from the peripheral blood from people of RA and normal person were used. Real-time PCR was performed to detect the expression of MiR-128-3p, while the protein expression of tumor necrosis factor-α-induced protein 3 (TNFAIP3) was determined using Western blot. The levels of IL-6 and IL-17 were measured using enzyme-linked immunosorbent assay (ELISA). The expression of CD69 and CD25 was detected using flow cytometry. The RA mouse model was constructed for verification of the role of MiR-128-3p. Results: The expression of MiR-128-3p was significantly increased, while TNFAIP3 was decreased, the levels of IL-6 and IL-17 were also increased in the T cells of RA patients. Down-regulated MiR-128-3p significantly suppressed the expression of p-IkBα and CD69, and CD25in T cells. MiR-128-3p targets TNFAIP3 to regulate its expression. MiR-128-3p knockdown significantly suppressed the activity of nuclear factor κB (NF-κB) and T cells by up-regulating TNFAIP3, while cells co-transfected with si-TNFAIP3 abolished the effects of MiR-128-3p knockdown. The in vivo experiments verified the potential role of MiR-128-3p on RA. Conclusion: Down-regulated MiR-128-3p significantly suppressed the inflammation response of RA through suppressing the activity of NF-κB pathway, which was mediated by TNFAIP3.
