Abstract
OBJECTIVES Peripheral SpA (pSpA) is comprised of ReA, PsA, enteritis-associated arthritis and undifferentiated pSpA (upSpA). ReA and upSpA share T cell oligotypes and metabolomics in serum and SF. We investigated HLA-B27 subtypes and cytokines in serum and SF that were compared between ReA and upSpA. METHODS ReA and upSpA were compared in two cohorts. In cohort I (44 ReA and 56 upSpA), HLA-B27 subtyping was carried out. In cohort II (17 ReA and 21 upSpA), serum and SF cytokines were compared using a multiplex cytokine bead assay (27 cytokines). A total of 28 healthy controls with similar age and sex to cohort II were included for comparison of serum cytokine levels. RESULTS In cohort I, HLA-B27 was positive in 81.8% (36/44) of ReA and 85.71% (48/56) of upSpA patients. HLA-B27 typing was successful in 70 patients (30 ReA and 40 uSpA). HLA-B*2705 was the most common, followed by HLA-B*2704 and HLA-B*2707. Frequencies were the same between ReA and upSpA. In cohort II, 14 cytokines were detectable in the serum of patients. The levels of eight cytokines were higher than in the controls. The cytokine levels of ReA and upSpA were similar. Sixteen cytokines were detectable in the SF of patients. There was no statistical difference in the levels between ReA and upSpA. The cytokine profiles in sera and SF were also similar among HLA-B27-positive and negative patients. CONCLUSION ReA and upSpA have similar HLA-B27 subtype associations and similar cytokine profiles. They should be considered as a single entity during studies as well as clinical management.

Abstract
Cervus and cucumis peptides (Lugua polypeptides, LG) are traditional Chinese medicine, which are active components of polypeptide extracted from Sika deer bone and melon seed, and they contain bone induced polypeptide biological factors. Umbilical cord mesenchymal stem cell, (UC-MSC) have tissue repair multiple effects, anti-inflammatory, and immune regulation function, which become a very promising start in rheumatoid arthritis (RA) treatment. Hence, LG combined UC-MSC can significantly enhance the UC-MSC treatment of rheumatoid arthritis (RA).To explore the clinical curative effect and therapeutic mechanism of LG combined UC-MSC for treating RA.119 patients were divided into control and treatment groups, and both groups were treated with methotrexate tablets, leflunomide, and UC-MSC. But, LG were added to the treatment group. In vitro, the effects of LG on UC-MSC cell secretion of anti-inflammatory factors were also performed.The Health Assessment Questionnaire; the 28 joint disease activity score; C reactive protein; the erythrocyte sedimentation rate; rheumatoid factor; and anti-cyclic citrullinated peptide antibody were significantly reduced in treatment group 1 year after treatment (P < .05). In vitro, compared with the control group, the number of hepatocyte growth factor (HGF), the secretion of prostaglandin E2 (PGE2) and tumor necrosis factor-inducible gene 6 protein (TSG6) increased significantly (P < .05).LG combined UC-MSCs can significantly improve the curative effect of RA patients, while LG may reduce inflammatory cytokines, regulate immunity, improve microcirculation, and are conducive to UC-MSCs migration and the repair of damaged tissue.

Clinical correlates of HLA-B*27 and its subtypes in enthesitis-related arthritis variant of juvenile idiopathic arthritis in south Indian Tamil patients. Int J Rheum Dis 2019; 22:1289-1296. [PMID: 30884197 DOI: 10.1111/1756-185x.13551] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Revised: 02/02/2019] [Accepted: 02/24/2019] [Indexed: 01/12/2023]
Abstract
AIM The aim of the study was to assess the distribution of human leukocyte antigen (HLA)-B*27 subtypes and its correlation with disease phenotypes in children with enthesitis-related arthritis variant of juvenile idiopathic arthritis (JIA-ERA). METHOD One hundred and sixty patients (132 males, 28 females) satisfying the International League Against Rheumatism (ILAR) classification criteria for JIA-ERA were assessed and relevant demographic, clinical and radiographic data were documented. HLA-B*27 typing was done for all the patients and B*27 positive samples were subjected to high-resolution gene sequencing. The effect of duration of illness, HLA-B*27, its subtypes, and gender on the clinical phenotype were analyzed. RESULTS The mean age of disease onset was 12.69 ± 2.4 years with a male:female ratio of 4.7:1.0. HLA-B*27 was positive in 109/160 patients and HLA-B*27:04 was detected in 63% followed by B*27:05 (30%). Duration of illness was greater in patients with skeletal deformity, hip arthritis, sacroiliitis, cervical spine involvement and acute anterior uveitis (AAU) (P < 0.05). HLA-B*27 positivity was associated with a prolonged course of disease, higher incidence of AAU (14.7% vs 2%, P = 0.015), family history of spondyloarthritis (21.1% vs 5.9%; P = 0.015) and higher erythrocyte sedimentation rate as compared to HLA-B*27 negative patients (P < 0.01). The HLA-B*27:04 and *27:05 positive patients had similar clinical phenotypes. CONCLUSION Presence of HLA-B*27 and long duration of illness results in skeletal deformity, hip arthritis, sacroiliitis, cervical spine involvement and AAU. HLA-B*27:04 followed by B*27:05 are the most common HLA-B*27 subtypes in our study population and both have a similar clinical phenotype.

Abstract
Objectives The presence of human leukocyte antigen B27 (HLA-B27) is strongly associated with ankylosing spondylitis. HLA-B27 testing is routinely applied in the diagnosis of this disease. The aim of the present study was to compare two methods of HLA-B27 detection – a genetic sequence-based method and a flow cytometry assay. Material and methods Peripheral blood was obtained from 300 individuals with suspected spondyloarthropathy. Expression of HLA-B27 on the T cell surface was analysed by flow cytometry assay using GS145.2 monoclonal antibody specific for HLA-B27. DNA was isolated from the whole blood. Genes coding for HLA-B27, -B40 and -B47:01 were detected by polymerase chain reaction using the MW02/MW09 primer pair. Then, positive samples were sequenced in order to discriminate allelic variations of the HLA-B27 gene. Results of sequencing were analysed using Chromas LITE 2.1.1 software, BLAST software and the IMGT/HLA database. Ambiguous samples were additionally analysed by polymerase chain reaction using E91 and E136 primers amplifying a 135-bp fragment of the human HLA-B27 gene. Results Among 300 samples, 76 were HLA-B27-positive on the basis of flow cytometry analysis. Genetic sequence analysis confirmed positivity of 73 from among 76 samples. Two hundred twenty six samples were HLA-B27-negative, whereas the result of one sample analysis was ambiguous. Fifty-three samples were identified as allelic variation 27:05, 19 samples as allelic variation 27:02, and one sample as allelic variation 27:07. Conclusions This study shows that the genetic sequence-based method and the flow cytometry assay give consistent results in 99% of cases. The performed genetic analysis proves that the majority of HLA-B27-positive samples belong to the 27:05 allelic variation, which is strongly associated with high risk of ankylosing spondylitis.

Abstract
OBJECTIVES To develop a duplex real-time TaqMan PCR assay for genotyping HLA-B*27 in the Chinese Han population. DESIGN AND METHODS A standard curve was constituted to deduce amplification efficiency, dynamic range and detection limit of the duplex real-time TaqMan PCR assay, whereas PCR-SBT (PCR with sequence-based typing) was used to evaluate the accuracy of the assay. RESULTS A linear standard curve for determining HLA-B*27 was obtained within the range of 10(1)-10(9) copies per reaction with the correlation coefficient of 0.99 and amplification efficiency of 98.30%. The detection limit was 3.09 copies per reaction. Complete concordance was found between the results obtained by the duplex real-time TaqMan PCR assay and PCR-SBT. Fifty-nine of the 178 genomic samples were HLA-B*27 positive and the other 119 were HLA-B*27 negative. CONCLUSIONS The duplex real-time TaqMan PCR approach appears to be a reliable, sensitive, rapid and high-throughput method to genotype HLA-B*27 in the Chinese Han population.

Abstract
Haplotype-specific extraction (HSE) allows the collection of individual alleles by separating diploid samples into their haploid components. The separation step is performed using magnetic beads in conjunction with allele-group-specific probes. The haplo-separated DNA samples can be directly typed with downstream applications such as sequence-specific oligonucleotide (SSO) typing, sequence-specific primer (SSP) typing, and sequence-based (SB) typing. Here we show that HSE permits the direct sequencing of an allele in its individual, separated state, including previously unknown alleles. Allele pair combinations that cannot be resolved by SSP, SSO, or generic SB typings can be unambiguously typed after the alleles are separated by HSE, which allows for new alleles to be easily detected without cloning. We show how HSE was performed to separate samples with locus-specific ambiguities in human leukocyte antigen (HLA)-B, which could not be resolved by means of generic SB typing for either sample. After haplotype-specific separation of the respective allele pairs, novel polymorphisms in the HLA-B*56 and HLA-B*44 alleles were clearly detected by SB typing.

Abstract
HLA-B27 is strongly associated with ankylosing spondylitis (AS). As typing for HLA-B27 is routinely performed by serological methods, false-positive results can be generated. Therefore, several more accurate molecular methods have been developed for HLA-B27 genotyping. We describe a real-time PCR method for the detection of the HLA-B27 allele using sequence-specific primers (SSP) combined with a fluorogenic MGB probe (minor groove binder probe), a novel type of TaqMan probe. The MGB increases the melting temperature (T(m)) of the probe, allowing the use of shorter probes. Moreover, the use of a non-fluorescent quencher (NFQ) attached to the MGB probe improves the efficiency of fluorescence quenching, thus providing a very low fluorescent background. We tested this method on 150 subjects (41 HLA-B27 positive and 109 HLA-B27 negative) who underwent routine HLA-B27 serological testing by flow cytometry (FC). Serology and our TaqMan assay gave identical results in all cases and no false positive or negative results were observed. A graphical representation of fluorescence and normalized reporter signal (DeltaRn) values demonstrated that HLA-B27 positive and HLA-B27 negative samples formed two tight clusters making it possible to clearly differentiate between HLA-B27 positive and negative samples. This single tube PCR method for the detection of HLA-B27 should be particularly suitable for the routine analysis of large numbers of samples in the laboratory.

Abstract
HLA-B*27 is known to be associated with ankylosing spondylitis and several methods have been applied to determine its presence or absence. In this report two molecular methods were used for detection of B*27. The polymerase chain reaction sequence-specific primer (PCR-SSP) method was performed to detect the presence or absence of B*27, whereas the sequence-based typing method (SBT) was used to identify the B*27 subtype. The PCR-SSP method used to detect B*27 was updated to enable the detection of all B*27 alleles. The typing results obtained by this method were compared with the serological typings of 262 individuals. Fifty of them were found to be B*27 positive by PCR-SSP and 46 also showed positive serological reactions with B27-specific sera. The four discrepancies were the result of the presence of B*2712 in three individuals and B*2715 in one individual; both alleles showed no serological reactions with B27-specific antisera. With SBT the sequences of exons 1 through 4 were determined to unequivocally assign the B*27 alleles. Eleven different subtypes were detected in 78 individuals, including three new B*27 alleles: B*27054, B*2715 and B*2717. The allele B*27054 showed an allelic drop out when exon 3 was amplified. Three differences with B*27052 were demonstrated; one in exon 1, one in intron 1 and one in intron 2, the latter being responsible for the allelic drop out. The B*2715 allele was serologically not detectable with several B27-specific sera, but showed Bw4-positive reactions. The sequence of B*2715 showed two mismatches with B*2704. The sequence of B*2717 showed one mismatch with B*27052 at position 248 (A-->T), which was considered to be a conserved position in all B alleles.

Abstract
We describe the use of restriction analysis on PCR-amplified DNA for detecting all B*27 subtypes except B*2710 and B*2711 (i.e. from B*2701 to B*2709). After detecting B*27 by Sty I, double digestions consisting of Sty I plus another informative enzyme led to subtype assignment. We used mismatched primers to create restriction sites when necessary. The method avoids group-specific amplifications and other laborious optimization procedures. It was successfully tested on a panel of well characterized cell lines covering different B*27 subtypes. Then, we studied a group of 57 ankylosing spondylitis patients and 746 controls from the south of Spain. B*27 showed a very strong association with the disease (OR=211.27, P=10(-7)). B*2702 and B*2705 distribution in controls (20% and 77.1%, respectively) differed from previously reported data in the Spanish population. We unexpectedly found the B*2707 allele in our population (one control).

Abstract
The system was designed with emphasis on the identification HLA-B alleles and genotypes associated or potentially associated with seronegative arthritides. By using a combination of multiplex SSP and PCR-RFLPs, the assays can be economically performed on a large range of sample sizes in diagnosis and epidemiology. 24 HLA-B alleles and subtypes can be discriminated, including options for PCR-RFLP or sequence specific amplification of the allele groups B27 and B60 (B*4001 and B*4007). In addition, the internal control carries central MHC polymorphisms, which can help to identify HLA extended halplotypes. False negatives, caused by preferential amplification of the internal control under suboptimal PCR conditions, were prevented by employing new, optimized PCR buffer. Four of the HLA-B primers were pooled into a multiplex reaction whose products were subtyped by digestion with seven restriction endonucleases. Specificity and sensitivity were verified in a panel of 68 homozygous cell lines and 200 heterozygous samples. An HLA-B*27-B*40 hybrid allele was observed in 3 out of 95 B*27-positive individuals from Berlin, Germany. Such an allele could be mistyped by some published assays as a B*27/B*40 heterozygote, a genotype reported to confer an increased risk for ankylosing spondylitis.
