Infections Cause Reactive Arthritis

Identification of endogenously presented peptides from Chlamydia trachomatis with high homology to human proteins and to a natural self-ligand of HLA-B27.JJ Cragnolini, JA de Castro. Mol Cell Proteomics 2008 Jan;7(1):170-180. "Mass spectrometry-based comparative analysis of HLA-B27-bound peptide pools led to identification of three HLA-B27 ligands differentially presented in the transfectant cells. Sequencing of these peptides confirmed that they were derived from the bacterial DNA primase. One of them, spanning residues 211-221, showed 55% sequence identity with a known self-ligand of HLA-B27 derived from its own molecule. The other two bacterial ligands, P-(112-121) and P-(112-122), were derived from the same region and differed in length by one residue at the C terminus. Both peptides showed >50% identity with multiple human protein sequences that possessed the optimal peptide motifs for HLA-B27 binding."

A comparison of self-reported joint symptoms following infection with different enteric pathogens: effect of HLA-B27. P Schiellerup, KA Krogfelt, H Locht. J Rheumatol 2008 Mar;35(3):480-487. 2105 patients with positive fecal culture. "[Reactive joint pain] was reported by 294 subjects: Campylobacter, 131 (13.1%); Salmonella, 104 (16.8%); Yersinia, 21 (23.1%); Shigella, 10 (9.8%); and E. coli, 28 (9.7%). There was a significant association between severity of gastroenteritis and development of arthralgia (p = 0.001). The odds ratio (OR) for JPrea in an HLA-B27-positive individual was 2.62 (95% CI 1.67-3.93) for the entire group. A significant association between JPrea and HLA-B27 was found for Salmonella, Shigella, and Yersinia; not, however, for Campylobacter and E. coli. HLA-B27-positive patients had a significantly increased risk for severe joint symptoms."

Symptomatic acute reactive arthritis after an outbreak of salmonella. S Rohekar, FW Tsui, HW Tsui, N Xi, R Riarh, R Bilotta, RD Inman. J Rheumatol 2008 Aug;35(8):1599-1602. 592 acute gastroenteritis patients. "62.5% of respondents reported extraintestinal symptoms that were consistent with ReA. The most commonly reported features were joint pain, swelling or stiffness (46.2%), stiffness > 30 min (35.6%), ocular symptoms (24.0%), and visibly swollen joints (19.2%). Subjects with Salmonella infection had a similar incidence of HLA-B27, regardless of whether they developed symptoms consistent with ReA or not. Notably, HLA-B27 was present more frequently in those who developed Salmonella infection than in healthy controls (OR 3.0)."

Reactive arthritis following culture-confirmed infections with bacterial enteric pathogens in Minnesota and Oregon: a population-based study.JM Townes, AA Deodhar, ES Laine, K Smith, HE Krug, A Barkhuizen, ME Thompson, PR Cieslak, J Sobel. Ann Rheum Dis 2008 Dec;67(12):1689-1696. " A total of 6379 culture-confirmed infections were reported; 70% completed screening interviews. Of these, 575 (13%) developed possible ReA; incidence was highest following Campylobacter (2.1/100,000) and Salmonella (1.4/100,000) infections. Risk was greater for females (relative risk (RR) 1.5, 95% CI, 1.3 to 1.7), adults (RR 2.5, 95% CI, 2.0 to 3.1) and subjects with severe acute illness (eg, fever, chills, headache, persistent diarrhoea). Risk was not associated with antibiotic use or human leukocyte antigen (HLA)-B27. A total of 54 (66%) of 82 subjects examined had confirmed ReA. Enthesitis was the most frequent finding; arthritis was less common. The estimated incidence of ReA following culture-confirmed Campylobacter, E coli O157, Salmonella, Shigella and Yersinia infections in Oregon was 0.6-3.1 cases/100,000."

Chlamydiae as etiologic agents in chronic undifferentiated spondylarthritis. JD Carter, HC Gérard, LR Espinoza, LR Ricca, J Valeriano, J Snelgrove, C Oszust, FB Vasey, AP Hudson. Arthritis Rheum 2009 May;60(5):1311-1316. 26 undifferentiated spondylarthritis patients, 167 osteoarthritis patient controls. "Sixteen of them (62%) were positive for C trachomatis and/or C pneumoniae DNA (10 for C trachomatis, 4 for C pneumoniae, and 2 for both). PCR analysis of ST revealed the presence of Chlamydia significantly more frequently in patients with uSpA than in OA controls (P<0.0001). No specific clinical characteristics differentiated Chlamydia-positive from Chlamydia-negative patients. PBMCs from 4 of the 26 uSpA patients (15%) were positive for Chlamydia, and Chlamydia was found in ST from 2 of these 4 patients."

Endogenous processing and presentation of T-cell epitopes from Chlamydia trachomatis with relevance in HLA-B27-associated reactive arthritis. JJ Cragnolini, N García-Medel, JA de Castro. Mol Cell Proteomics 2009 Aug;8(8):1850-1859. "A predicted T-cell epitope, from the CT610 gene product, was presented by HLA-B27. This is, to our knowledge, the first endogenously processed epitope involved in HLA-B27-restricted responses against C. trachomatis in reactive arthritis. A second predicted epitope, from the CT634 gene product, was not detected. Instead a non-predicted nonamer from the same protein was identified. Both bacterial peptides showed very high homology with human sequences containing the HLA-B27 binding motif."

Interferon-γ contributes to HLA-B27-associated unfolded protein response in spondyloarthropathies. Y Feng, J Ding, CM Fan, P Zhu. J Rheumatol 2012 Mar;39(3):574-582. "Tumor necrosis factor-α (TNF-α) and IFN-α, IFN-ß, and IFN-γ were found to have activated the HLA-B27 promoter in the U937 cell line (p < 0.05). Following stimulation with IFN-γ, the expressions of GRP78, CHOP and XBP-1 in HLA-B27-transfected U937 cells and PBMC of HLA-B27-positive AS patients were more intense than those in A2-U937 cells, HLA-B27-negative AS patients, or healthy controls (p < 0.05)."

Phosphorylation of STAT-1 serine 727 is prolonged in HLA-B27-expressing human monocytic cells. M Ruuska, AS Sahlberg, K Granfors, MA Penttinen. PLoS One 2013;8(1):e50684. "We discovered that the phosphorylation of STAT-1 serine 727 is prolonged in cells expressing misfolding forms of HLA-B27 after S. enteritidis infection, whereas in mock cells and in cells expressing mutated, non-misfolding HLA-B27 the phosphorylation of serine 727 is transient. Interestingly, STAT-1 serine 727 phosphorylation is partly dependent on PKR. In addition, more STAT-1 is localized in the nucleus of HLA-B27-expressing cells, even before an external trigger, when compared to mock cells... This is of interest since the phosphorylation of serine 727 on STAT-1 is suggested to contribute to macrophage activation and promote inflammatory responses."

Identification of immunogenic HLA-B*27:05 binding peptides of salmonella outer membrane protein in patients with reactive arthritis and undifferentiated spondyloarthropathy.AK Singh, A Aggarwal, S Chaurasia, R Misra. J Rheumatol 2013 Feb;40(2):173-185. 23 patients with ReA/uSpA, 10 with rheumatoid arthritis (RA), and 10 healthy individuals. "Nineteen of 23 SFMC from ReA/uSpA showed a significant proliferative response to salmonella OMP, with minimal response of PBMC (1/10) from ReA/uSpA, SFMC from RA (1/10), or PBMC from controls (1/10). Nine salmonella OMP peptides... were identified. Response to QRAEMLPTL was seen in 6/7 HLA-B*27:05-positive patients. All immunogenic peptides had sequence similarity with peptides from arthritogenic bacterial proteins, while 5 had similarity with peptides from human proteins."

Normal inflammasome activation and low production of IL-23 by monocyte-derived macrophages from subjects with a history of reactive arthritis.E Välimäki, S Aittomäki, L Karenko, J Kantonen, T Pettersson, U Turunen, S Matikainen, M Leirisalo-Repo, H Repo. Scand J Rheumatol 2013;42(4):294-298. 10 HLA-B27-positive subjects with previous ReA triggered by Yersinia enterocolitica O:3 infection and 20 healthy controls (10 HLA-B27 positive). "TNF-α production from macrophages upon co-stimulation of LPS and MDP increased in the order ReA group < HLA-B27-positive reference group < HLA-B27-negative reference group (p for a trend = 0.027). Similarly, Yersinia-induced TNF-α and IL-23 production increased in the same order (p for trend for TNF-α = 0.036; p for trend for IL-23 = 0.026)."

The role of intracellular organisms in the pathogenesis of inflammatory arthritis. A Singh, S Karrar. Int J Inflam 2014;2014:158793. Review. "The classic bacteria associated with ReA are Gram-negative obligate or facultative intracellular aerobic bacteria with a lipopolysaccharide-containing outer membrane. The primary focus of infection is thought to be through the mucus membrane, either in the gut or in the urogenital tract. Gastrointestinal microbes commonly include Salmonella, Shigella, and Campylobacter jejuni. Less frequently diagnosed infections include Campylobacter lari, Chlamydia psittaci, and Clostridium difficile. Chlamydia trachomatis is the most common cause of genital infection and the most common triggering infection for ReA."
