Jinyoung Park, Duk Hyun Sung
Polymyalgia rheumatica (PMR) is almost an exclusive disease of adults over the age of 50, and only a few cases have been reported. Two 46-year-old females visited our locomotor pain clinic with multiple joint pain with increased acute phase reactants. Rheumatologic markers, and HLA-B27 were checked. Serum protein electrophoresis and serum immunofixation electrophoresis, imaging studies including plane image, sonography, and magnetic resonance image was done. (18)F-Fludeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) showed characteristic findings of PMR, without evidences of sacroiliitis...

Quantitative peptide-binding motifs of MHC class I alleles provide a valuable tool to efficiently identify putative T cell epitopes. Detailed information on equine MHC class I alleles is still very limited, and to date, only a single equine MHC class I allele, Eqca-1*00101 (ELA-A3 haplotype), has been characterized. The present study extends the number of characterized ELA class I specificities in two additional haplotypes found commonly in the Thoroughbred breed. Accordingly, we here report quantitative binding motifs for the ELA-A2 allele Eqca-16*00101 and the ELA-A9 allele Eqca-1*00201...

The study of ankylosing spondylitis (AS) has made significant progress over the last decade. Genome-wide association studies have identified and further substantiated the role of susceptibility genes outside the major histocompatibility complex locus. However, human leukocyte antigen (HLA)‑B27 has been suggested to be important in the pathogenesis of AS, contributing to ~20.1% of AS heritability. The current review will present the classical and non‑classical forms of HLA-B27, as well as their pathogenic roles, and further discuss the hypotheses regarding the potential pathogenesis of AS...

Ochronosis is a late developing complication of alkaptonuria, a black brownish pigment in the fibrous and cartilaginous tissues. Although most previous studies reported alkaptonuria and back pain due to ochronosis, thoracic myelopathy is an extremely rare complication. In this report, a paraparetic patient who has ochronotic spondiloarthropathy with the presence of HLA B27 antigen is described. He had low back and leg pain and morning stiffness for 5 yrs. Last year, these were followed by tingling, numbness, and weakness the in lower extremities and he was operated on with preliminary diagnosis of prolapsed disc herniation and cord compression...

HLA-B27 is a class I major histocompatibility (MHC-I) allele that confers susceptibility to the rheumatic disease ankylosing spondylitis (AS) by an unknown mechanism. ERAP1 is an aminopeptidase that trims peptides in the endoplasmic reticulum for binding to MHC-I molecules. ERAP1 shows genetic epistasis with HLA-B27 in conferring susceptibility to AS. Male HLA-B27 transgenic rats develop arthritis and serve as an animal model of AS, whereas female B27 transgenic rats remain healthy. We used large-scale quantitative mass-spectrometry to identify over 15,000 unique HLA-B27 peptide ligands, isolated after immunoaffinity purification of the B27 molecules from the spleens of HLA-B27 transgenic rats...

Ankylosing spondylitis (AS) is a spinal arthritic disease that is often associated with human leukocyte antigen (HLA)-B27, while only part of HLA-B27 carriers become AS patients. T cells have been reported to play an important role in the pathology of AS. T-cell immunoglobulin and mucin-domain-containing molecule 3 (Tim-3) and programmed death-1 (PD-1) have been known to negatively regulate the immune response. In this study, we used flow cytometry to analyze the immunological differences of peripheral bloodfrom 21 patients with AS, 22 cases who didn't have AS but were found to be HLA-B27 positive (HLA-B27+ group), and 16 normal healthy individuals (Healthy group)...

Intraocular Candida infections are overall rather rare; nevertheless they are often found as endogenous infections after Candida sepsis and can be sight-threatening. The most common manifestations are either a sole chorioretinitis or an endophthalmitis. Here we report the case of a 35-year-old man developing Candida infiltrations in the lens capsule and behind the iris after corticosteroid treatment of a presumed HLA-B27-positive iritis. The patient suffered from a life-threatening intensive care stay with positive Candida blood cultures earlier after intestinal perforation...

BACKGROUND: Patients with juvenile idiopathic arthritis (JIA) on non-steroidal anti- inflammatory drugs (NSAIDs) may experience abdominal pain. In adults, NSAID use has been linked to an increase in fecal calprotectin (FC) levels, a surrogate marker for gut inflammation. In JIA, data on gut inflammation related to drug use is scarce. METHODS: JIA patients followed up at the outpatient pediatric rheumatology clinic in Children's Hospital, Helsinki University Hospital, Helsinki, Finland were routinely assessed for FC if they complained about abdominal pain, had an elevated erythrocyte sedimentation rate (ESR) or used NSAIDs on a daily basis...

REVIEW
Joachim Sieper, Denis Poddubnyy
The term axial spondyloarthritis covers both patients with non-radiographic and radiographic axial spondyloarthritis, which is also termed ankylosing spondylitis. The disease usually starts in the third decade of life with a male to female ratio of two to one for radiographic axial spondyloarthritis and of one to one for non-radiographic axial spondyloarthritis. More than 90% heritabilty has been estimated, the highest genetic association being with HLA-B27. The pathogenic role of HLA-B27 is still not clear although various hypotheses are available...

Some HIV-1-infected patients develop broad and potent HIV-1 neutralizing antibodies (bNAbs) that when passively transferred to mice or macaques can treat or prevent infection. However, bNAbs typically fail to neutralize coexisting autologous viruses due to antibody-mediated selection against sensitive viral strains. We describe an HIV-1 controller expressing HLA-B57*01 and HLA-B27*05 who maintained low viral loads for 30 years after infection and developed broad and potent serologic activity against HIV-1. Neutralization was attributed to three different bNAbs targeting nonoverlapping sites on the HIV-1 envelope trimer (Env)...

Involvement of tendons and tendon sheaths is frequently found in the most common inflammatory systemic diseases, rheumatoid arthritis and spondyloarthritis. In rheumatoid arthritis tendon manifestations occur as tenosynovitis, with swelling and pain of the tendons mainly on the hands and feet. In spondyloarthritis the involvement of tendons presents as enthesitis with pain and swelling directly at the attachment points of tendons to the bony structures and more commonly in the lower extremities. Pathological alterations of tendons can be normally visualized by sonography and only sometimes with magnetic resonance imaging (MRI) or scintigraphy...
