“…On the other hand, in our study [30] some HLA-B*35 patients complained of pain and swelling of the joints and tendons or these symptoms were detected by a physician during a clinical examination. We found that the HLA-B*35 allele was associated with a five-fold greater chance of finding peripheral joint synovitis in un-axSpa patients.…”

“…Given that we also noticed an increased frequency of the HLA-B*35 allele in patients with symptoms of axSpA and without any other known cause of axSpA, we conducted a study in which we confirmed the connection between sacroiliitis detected by MRI and the HLA-B*35 allele in patients with un-axSpA [30].…”

“…The association between HLA-B*35 allele and SpA, whether in the axial or the peripheral form of the disease, has long been known [20][21][22][23][24][25][26][31][32][33]. Indeed, in our study, a large proportion of the HLA-B*35 positive patients with preliminary diagnosis of un-axSpA had joint and tendon pain and swelling according to patients or their physicians [30], which we evaluated by US. In current practice in rheumatology, US is used to evaluate peripheral joint and periarticular abnormalities, whether to confirm or refute them [40] or to detect their subclinical presence, which would otherwise be missed on examination [41].…”

“…US was performed in 72 HLA-B*35 positive patients with preliminary diagnosis of un-axSpA and joint and tendon problems. These patients were part of our cross-sectional study that showed an association between sacroiliitis detected by MRI and HLA-B*35 allele after patients with HLA-B*27 allele, psoriasis, IBD, preceding infections and juvenile SpA were excluded [30]. Detailed history taking and additional laboratory analysis were performed to rule out other types of arthritis.…”

Background: We aimed to investigate possible association between the HLA-B*35 allele and peripheral arthritis, tenosynovitis and enthesitis. Methods: Ultrasound of peripheral joints and tendons was performed in 72 HLA-B*35 positive patients with preliminary diagnosis of undifferentiated axial form of spondyloarthitis and joint and tendon pain. Patients with other known types of axial and peripheral spondyloarthritis were excluded as well as patients with other known types of arthritis. Results: Pathological changes were found in the joints of 33 (46%) patients and on the tendons in 13 (18%) patients. The most common ultrasound findings were joint effusion and synovial proliferation with positive power Doppler signal grade 1. The most common ultrasound finding in patients with painful tendons was tenosynovitis. A higher disease activity and an increased incidence of elevated CRP (≥5 mg/L) were more often observed in the group with positive ultrasound findings. Conclusion: In this study, we showed that the HLA-B*35 allele could be a potential risk factor for developing peripheral arthritis, but not for tenosynovits and enthesitis in patients with the undifferentiated axial form of spondyloarthritis. This result may influence the follow up of these patients, especially since it gives us an opportunity to consider the use of different types of DMARDs in the treatment of these patients.

“…ere are currently 86 polypeptide isoforms and 97 nucleotide variants present in this group [25]. Apart from its well-established association with the accelerated progression of HIV infection to AIDS, HLA-B * 35 has been reported to be associated with Juvenile idiopathic arthritis-related uveitis, self-limiting unclassified rheumatism, sacroiliitis in undifferentiated spondyloarthropathy, and oral aphthosis [26][27][28][29][30][31][32]. e literature on ocular involvement in HLA-B * 35 positivity is scarce and shows its presence in up to 24% of uveitis patients in a small-sized prospective study [33].…”

Introduction. There is a scarcity of information available on clinical and laboratory features of adult-onset idiopathic autoimmune uveitis. Therefore, we conducted a single centre descriptive cross-sectional study. Patients and Methods. A chart review of all patients with idiopathic autoimmune uveitis with onset after 18 years of age who were referred to the rheumatology department between January 2017 and December 2018 was performed. Their clinical features, demographic features, and HLA-B genotypes were documented and described. Results. Out of 210 patients referred to rheumatology, 66 were found to have uveitis, and 16 of these had an adult-onset idiopathic autoimmune uveitis. Apart from a slight female preponderance (62.5%), our patients were characterized by a high proportion of panuveitis (4 out of 16, i.e., 25%). There was an increased frequency of occurrence of synechiae (5 out of 16, i.e., 31.3%), retinal vasculitis (4 out of 16, i.e., 25%), optic disc edema (3 out of 16, i.e., 18.8%), and cystoid macular edema (seen in 2 patients, i.e., 12.5%). These features correlated with the anatomical subtypes. Retinal vasculitis and optic disc edema present in three fourth of all panuveitis cases were the most prominent features. The odds of finding HLA-B∗35 in retinal vasculitis were 33 times higher than odds of finding it in idiopathic autoimmune uveitis patients not having retinal vasculitis (OR 33; 95% CI 1.6–698). Conclusion. Idiopathic autoimmune uveitis in our patients is characterized by a high frequency of panuveitis and retinal vasculitis, and complications with a probable association between HLA-B∗35 and retinal vasculitis.

PurposeTo describe a unique presentation of optic neuritis associated with positive HLA-B35.ObservationsA woman presented with unilateral retro-orbital pain, mildly decreased vision, and optic disc edema with new-onset aphthous ulcers. Color vision was preserved, and no visual field deficits were noted. Diagnostic imaging demonstrated retrobulbar optic nerve enhancement, with genetic testing revealing HLA-B35 positivity. Treatment with high-dose oral steroids for 3 days resolved all symptoms, and the patient remained stable for at least 2 months.Conclusions and importanceIn addition to rheumatic conditions and oral lesions, HLA-B35 can be linked to optic neuritis. This relationship highlights the need to further explore genetic risk factors associated with optic neuritis and the potential need for human leukocyte antigen (HLA) testing in unusual cases of optic neuritis.
