Primary Hypertrophic Osteoarthropathy: A Case Series, Varuni Pragya, Mahabaleshwar Mamadapur Dr, Rahul Bisaralli Dr, Deepak Benny Dr, Purna Bansal

Digital Journal of Clinical Medicine

Skeletal dysplasia encompasses a spectrum of over 400 rare inheritable skeletal abnormalities typically manifested early in childhood. Hypertrophic Osteoarthropathy is a clinical syndrome marked by abnormal skin and osseous tissue proliferation at the distal extremities. It is characterized by unique clinical features such as digital clubbing, periostosis of tubular bones, and synovial effusions.

We report three cases of HPOA for further understanding and insight into this infrequent cause of clubbing. Case 1 involved a 25-year-old male presenting with joint pain, primarily in wrists and knees, accompanied by progressive swelling in both lower limbs for the past 3 years. Case 2 …

Advances in Clinical Medical Research and Healthcare Delivery

Abstract

Introduction: Pigeon Breeder’s Pneumonitis (PBP) results due to a complex pathophysiology that includes exposure to avian antigens. Susceptibility has been linked to human leukocyte antigen (HLA) class II, though consensus has not been reached. The goal of this systematic review is to further elucidate the association between PBP and HLA-DR subtypes.

Methods: Databases utilized included PubMed, Google Scholar, ScienceDirect, and Cochrane Library. Inclusion required a minimum of three studies in English presenting HLA-DR alleles of PBP and control subgroups. Exclusion was due to insufficient data or non-feasible control groups. Forest plots were created for HLA-DR subtypes’ association …

Maackia Amurensis Seed Lectin (Masl) Increases Movement Velocity Of Mice With Tnfα Induced Rheumatoid Arthritis, Amanda A. Greenspan, Kelly L. Hamilton, Alan J. Shienbaum, Bradford Fischer, Andrea Bottaro, Gary S. Goldberg

Rowan-Virtua Research Day

Up to 70 million people around the world suffer from rheumatoid arthritis. Current treatment options have varied efficacy and can cause unwanted side effects. New approaches are needed to treat this condition. Sialic acid modifications on chondrocyte receptors have been associated with arthritic inflammation and joint destruction. The transmembrane mucin receptor protein podoplanin (PDPN) has been identified as a functionally relevant receptor that presents extracellular sialic acid motifs. PDPN signaling promotes inflammation and invasion associated with arthritis and, therefore, has emerged as a target that can be used to inhibit arthritic inflammation. Maackia amurensis seed lectin (MASL) can target PDPN …

Adipocytes And Innate Immunity In Systemic Sclerosis, Nancy Wareing

Dissertations & Theses (Open Access)

Systemic sclerosis (SSc; scleroderma) is a chronic systemic autoimmune and connective tissue disorder characterized by vasculopathy, autoimmune phenomena, and widespread fibrosis. Skin thickening and tightening is the cardinal feature of SSc and is responsible, in part, for the considerable morbidity of this disease. There are currently no targeted treatments for skin manifestations in SSc, primarily due to our fragmented understanding of its pathophysiologic mechanisms. In PART I, we report a previously unappreciated link between aberrant expression of the developmental gene sine oculis homeobox homolog 1 (SIX1) in skin-associated adipocytes in SSc skin and the early loss of dermal white adipose …

Antibodies For Β2-Microglobulin And The Heavy Chains Of Hla-E, Hla-F, And Hla-G Reflect The Hla-Variants On Activated Immune Cells And Phases Of Disease Progression In Rheumatoid Arthritis Patients Under Treatment, Mepur H. Ravindranath, Narendranath M. Ravindranath, Carly J. Amato-Menker, Fatiha El Hilali, Senthamil R. Selvan, Edward J Filippone, Luis Eduardo Morales-Buenrostro

Department of Medicine Faculty Papers

Rheumatoid arthritis (RA) is a progressive, inflammatory, autoimmune, symmetrical polyarticular arthritis. It is characterized by synovial infiltration and activation of several types of immune cells, culminating in their apoptosis and antibody generation against "altered" autoantigens. β2-microglobulin (β2m)-associated heavy chains (HCs) of HLA antigens, also known as closed conformers (Face-1), undergo "alteration" during activation of immune cells, resulting in β2m-free structural variants, including monomeric open conformers (Face-2) that are capable of dimerizing as either homodimers (Face-3) or as heterodimers (Face-4). β2m-free HCs uncover the cryptic epitopes that can elicit antibodies (Abs). We report here the levels of IgM and IgG Abs …

OBJECTIVES: Juvenile idiopathic arthritis (JIA) is a heterogeneous group of diseases, comprising seven categories. Genetic data could potentially be used to help redefine JIA categories and improve the current classification system. The human leucocyte antigen (HLA) region is strongly associated with JIA. Fine-mapping of the region was performed to look for similarities and differences in HLA associations between the JIA categories and define correspondences with adult inflammatory arthritides.

METHODS: Dense genotype data from the HLA region, from the Immunochip array for 5043 JIA cases and 14 390 controls, were used to impute single-nucleotide polymorphisms, HLA classical alleles and amino acids. …

Educating those currently working in primary care about adding occupational therapy services can have a significant impact on the profession of …

Analysis Of Humira, Electro-Acupuncture, And Pulsatile Dry Cupping On Reducing Joint Inflammation In Patients With Rheumatoid Arthritis, Natalie Noll

Auctus: The Journal of Undergraduate Research and Creative Scholarship

Humira, an anti-TNF drug aimed at decreasing inflammation in Rheumatoid Arthritis patients, can cause skin diseases from rashes to skin cancer. Humira works by blocking the chemical receptor RANKL which inhibits the production of osteoclasts. Osteoclasts are cells that attack and eat bone and cartilage therefore an inhibitory mechanism would cause inflammation.. By analyzing Humira’s effect on the human body, Humira can be compared to other treatments such as electro-acupuncture and pulsatile dry cupping to determine the viability of these alternative treatment methods in regards to their abilities to decrease inflammation in Rheumatoid Arthritis patients through blocking RANKL. An analysis …

Sympathetic Nerve Modulation Of Joint Pathology In Adjuvant-Induced Arthritis, Carlo Anthony Wood

Loma Linda University Electronic Theses, Dissertations & Projects

Background: There is increasing data suggesting a net increase in sympathetic tone plays an important role in rheumatoid arthritis. Several studies have reported altered distribution and density of autonomic nerves in patients with rheumatoid arthritis and animal models for the disease. This provides anatomical evidence that supports a neurally-mediated drive in inflammation and joint destruction. Methods: Adult rats were injected with complete Freund’s adjuvant. At 12 days post immunization, animals were randomly placed into a drug treatment group (SH1293, which interacts with - and ß2-ARs), an adjuvant arthritic group, or a control group. These animals were sacrificed at 14, 21, …

Retinoid X Receptor And Peroxisome Proliferator-Activated Receptor-Gamma Agonists Cooperate To Inhibit Matrix Metalloproteinase Gene Expression, Peter S. Burrage, Adam C. Schmucker, Yanqing Ren, Michael B. Sporn, Constance E. Brinckerhoff

Dartmouth Scholarship

We recently described the ability of retinoid X receptor (RXR) ligand LG100268 (LG268) to inhibit interleukin-1-beta (IL-1-β)-driven matrix metalloproteinase-1 (MMP-1) and MMP-13 gene expression in SW-1353 chondrosarcoma cells. Other investigators have demonstrated similar effects in chondrocytes treated with rosiglitazone, a ligand for peroxisome proliferator-activated receptor-gamma (PPARγ), for which RXR is an obligate dimerization partner. The goals of this study were to evaluate the inhibition of IL-1--induced expression of MMP-1andMMP-13 by combinatorial treatment with RXR and PPAR  ligands and to investigate the molecular mechanisms of this inhibition.
