The association of HLA-B27 with ankylosing spondylitis (AS) remains as one of the intriguing models that could exist between a molecule and human disease in medicine. Although it was reported in 1973, its contribution to AS and related spondyloarthritis continues to be a major challenge for scientific community. It is important to understand its etiopathogenic mechanism and its functions in these diseases. Although the diagnostic and prognostic roles of HLA-B27 in AS are still debated, there is an increasing interest for HLA-B27–based effects especially in HLA-B27(+) patients with AS. This review will focus in the examination of published reports regarding the influence of HLA-B27 status on the demographic and clinical features in AS, with specific interest to its role on AS severity.

AimsTo characterise the clinical features of human leucocyte antigen (HLA)-B27+acute anterior uveitis (AAU) patients with or without ankylosing spondylitis (AS) and investigate the retinal vascular involvement in these patients.MethodsA total of 1056 HLA-B27+ AAU patients (1525 eyes) were retrospectively studied from April 2008 to February 2016. Patients were divided into human leucocyte antigen (HLA)-B27+AS+ and HLA-B27+AS− group. Clinical features including the onset of uveitis, laterality, the age at first attack, clinical examinations, best corrected visual acuity (BCVA), abnormalities in fundus fluorescence angiography (FFA) and complications were determined and compared between these two groups.ResultsThere were 581 (55.0%) and 475 (45.0%) patients respectively classified into HLA-B27+AS+ and HLA-B27+AS− group. Males had a higher prevalence than females in the HLA-B27+AS+ group (75.2%) as compared with the HLA-B27+AS− group (51.8%, p<0.001). The HLA-B27+AS+ patients showed a higher percentage of bilateral/alternating involvement (47.3%) as compared with the HLA-B27+AS− group (36.6%, p=0.001). A higher percentage of fibrinous exudation, synechiae as well as complications including complicated cataract and secondary glaucoma were found in the HLA-B27+AS+ group as compared with the HLA-B27+AS− group. Worse visual outcome as indicated by a higher percentage of patients with BCVA <0.5 and with BCVA <0.05 was noted in the HLA-B27+AS+ group as compared with the HLA-B27+AS− group both before and after treatment. FFA showed mild capillary fluorescence leakage in the late phase with indistinctly defined margins on the peripheral retina in 39.3% of HLA-B27+ AAU patients. There was no difference concerning the retinal vascular involvement between these two groups.ConclusionsOur study confirmed that HLA-B27+AS+ patients show a higher percentage of males, more common bilateral involvement, a higher frequency of fibrinous exudates, synechiae and secondary glaucoma as compared with HLA-B27+AS− patients. Visual outcome was poorer, possibly due to the higher prevalence of complicated cataract in HLA-B27+AS+ patients. Retinal vascular involvement was not uncommon in HLA-B27+ AAU patients.

Abstract Background/Aims  The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is routinely used subjective outcome measurement of disease activity in Ankylosing Spondylitis (AS). BASDAI &gt; 4 is used as a criterion for commencing anti-TNF therapy. Previous studies shown BASDAI correlation with MRI has been proven to be weak. We did this study to systemically compare clinical and radiological data of patients with AS and to look for the degree of correlation between BASDAI score and MRI changes positive for spondyloarthritis in our cohort of patients. Methods  A retrospective analysis of AS patients attending Leicester spondylarthritis service at University Hospitals Leicester Trust (UHL) was carried out. Clinical characteristics such as HLA-B27 status, extra-articular features, family history of AS and CRP measurement were obtained from online systems and clinic letters. Online records were reviewed to see if patients had a MRI of the sacroiliac joints along with a BASDAI score at the time of MRI. Medcalc calculator was used for statistical analysis. Results  A total of 106 patients were analysed with a mean age of 45.6 +/- 11.6 years (M = 62, F = 44) with mean BASDAI of 5.0 +/- 2.5. Mean CRP was 17.01+/- 30.4 (median CRP 6.5). 61% (n = 65) were HLA-B27 positive. 70 of 106 patients had a sacroiliac MRI scan which could be reviewed to a satisfactory level to determine whether disease is present or not. Two results were statistically significant when comparing active versus no active lesions on MRI: inflammatory back pain and anti-TNF therapy (Table 1).

Only inflammatory back pain and anti-TNF therapy correlated with MRI disease activity. There was no difference in clinical features including HLA-B27 between patients with active and inactive MRI. Thus, BASDAI as a criterion for biologic therapy may need re-considering. Disclosure  N. Jain: None. S. Byravan: None. J. Stairs: None. W. Rennie: None. M.

Abstract Objective This nationwide study aimed to reveal the prevalence of ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-ax SpA), and the positive rate of human leukocyte antigen (HLA) among these patients in Japan. Methods The first survey was conducted in 2221 randomly selected facilities (26.3%) in September, 2018, where the patients with AS/nr-ax SpA were taken care of from January to December, 2017. We estimated the total number of these patients using response and extraction rate. A second survey was conducted in 117 facilities (49.8%) to assess for HLA-B 27 positivity rate and clinical features. Results The estimated total number of the patients with AS and nr-ax SpA were 3200 (95% confidence interval [CI]: 2400–3900) and 800 (530–1100), suggesting that the prevalence of AS and nr-ax SpA in general population were 2.6/100,000 (0.0026%) and 0.6/100,000 (0.0006%), respectively. Although 55.5 % (76/137) of patients with AS were HLA-B27 positive, those whose age of onset was estimated to be over 50 years tended to undergo less HLA-B27 testing. Conclusion This study revealed the lower prevalence of AS/nr-ax SpA in Japan, compared to those in other countries. Further studies are required to reveal the association of HLA-B27 with the clinical features.
