Peripheral and follicular helper T lymphocytes (Tph and Tfh, respectively) have an important role in B cell immune responses and the pathogenesis of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Although several studies on the number of Tph and Tfh cells in these conditions have been published, different phenotypes have been employed for their analysis. In this study, we assessed the levels and function of Tph and Tfh cells in blood samples from patients with RA and SLE by using an extended immunophenotype.
Materials and methods
In a cross-sectional pilot study, blood samples from twenty-seven patients with RA and fifteen with SLE, and twenty-six healthy controls were studied. The levels of Tph (CD4+PD-1+CXCR5−CD38+CD69+ICOS+) and Tfh (CD4+PD-1+CXCR5+CD38+CD69+ICOS+) cells were analyzed by flow cytometry. In addition, the function of Tph/Tfh cells was estimated by measuring the synthesis of IL-21 by these lymphocytes as well as the number of circulating plasmablasts (CD19+CD27+CD20−CD38hi).
Results
Increased percentages of Tph and Tfh lymphocytes were detected in patients with RA and SLE. Furthermore, the synthesis of IL-21 tended to be higher in both conditions, and higher levels of plasmablasts were detected in these patients, compared to controls. In patients with SLE, the number of Tph cells was associated with disease activity and with the levels of circulating plasmablasts, whereas in patients with RA a significant correlation between Tph cells and evolution time was observed.
Discussion and conclusions
Our data of Tph and Tfh lymphocytes, based in the analysis of an extended phenotype of these cells, provides further evidence on their involvement in the pathogenesis of RA and SLE.
简介和目的外周和滤泡辅助性T淋巴细胞(分别为Tph和Tfh)在B细胞免疫反应以及类风湿性关节炎(RA)和系统性红斑狼疮(SLE)的发病机制中起着重要作用。尽管已发表了多项关于这些疾病中 Tph 和 Tfh 细胞数量的研究,但分析时采用了不同的表型。在这项研究中,我们使用扩展免疫表型评估了 RA 和系统性红斑狼疮患者血液样本中 Tph 和 Tfh 细胞的水平和功能。材料和方法在一项横断面试验研究中,我们研究了 27 名 RA 患者、15 名系统性红斑狼疮患者和 26 名健康对照者的血液样本。通过流式细胞术分析了 Tph(CD4+PD-1+CXCR5-CD38+CD69+ICOS+)和 Tfh(CD4+PD-1+CXCR5+CD38+CD69+ICOS+)细胞的水平。结果在 RA 和系统性红斑狼疮患者中检测到 Tph 和 Tfh 淋巴细胞百分比增加。此外,与对照组相比,IL-21 在这两种情况下的合成量往往更高,在这些患者中检测到的浆细胞水平也更高。在系统性红斑狼疮患者中,Tph 细胞的数量与疾病活动和循环浆细胞的水平有关,而在 RA 患者中,Tph 细胞与演变时间之间存在显著的相关性。讨论与结论我们对 Tph 和 Tfh 淋巴细胞的数据基于对这些细胞扩展表型的分析,为它们参与 RA 和系统性红斑狼疮的发病机制提供了进一步的证据。

The exposure to artificial gravity (AG) through human centrifugation is the basis of the treatment called gravity therapy (GT), in which the mechanical stimulation over the vessel wall, induces the synthesis and release of prostacyclin. It has been used for more than four decades in Uruguay in the treatment of different vascular-based pathologies. In patients with systemic sclerosis (SSc) it has shown good benefits and excellent safety profile over the years. However, there is a lack of knowledge in the scientific community about GT and its results.
Objective
To evaluate the effectiveness of GT in cutaneous and vascular involvement, in the quality of life and functional capacity and its safety profile in patients with SSc.
Methodology
It is a descriptive and retrospective study of patients with SSc assisted in an autoimmunity center in Montevideo, treated with GT in the last 10 years.
Results
Fifty patients were included, 48 women (96%) and 2 men (4%) with a mean age of 62 ± 12 years. The mean time of evolution of SSc at the time of inclusion in the study at the beginning of GT was 6.8 ± 3.2 years and 2.8 ± 3.2 years respectively. After GT, a significant improvement in the modified Rodnan skin score (mRSS) was observed (pre-GT 19.2 ± 8.7 vs post-GT 5.4 ± 5.0, P < .05), which was not related to the time of disease progression at the beginning of GT nor to the skin extension or immunological profile. The degree of improvement post-GT was related to a higher initial mRSS (R = 0.84, P < .05). Also, a significant improvement was observed in the number of patients with puffy fingers (pre-GT 50% vs post-GT 20% patients, P < .05), but not in telangiectasias, pitting scars or sclerodactyly. The severity of Raynaud's phenomenon significantly decreased (pre-GT: grade 3-4, 43/48 (89.6%) patients vs post-GT: grade ≤ 2, 42/47 (89.4%) patients, P < .05) as well as the vascular pain measured with VAS (0-10 scale) (pre-GT: 7.6 ± 2.2 vs post-TG: 1.4 ± 1.2, P < .05). The healing of digital ulcers was also recorded. Regarding the results reported by patients, 97% reported improvement in the quality of life and 89.5% improvement in the ability to carry out activities of daily living. No significant adverse effects were recorded.
Conclusions
GT improved cutaneous and vascular involvement, the quality of life and the functional capacity in patients with SSc with an excellent safety profile. Randomized, controlled clinical trials are needed to corroborate these observational results.

Background
Behcet's disease (BD) is a multisystem disorder prevalent along the historic Silk Road, with Behcet's uveitis (BU) representing a significant complication contributing to disability. Various studies have linked different HLA alleles with BD across diverse populations.
Methods
In this study, we investigated the association between HLA-B51:01/x and HLA-B27/x genotypes with Behcet's uveitis in 50 unrelated Iranian patients diagnosed with Behcet's uveitis, comparing them to a control group of 70 healthy individuals. Our analysis aimed to determine the susceptibility conferred by these alleles and assess their clinical relevance.
Results
Our findings indicate a notable susceptibility conferred by the HLA-B51:01/x genotype for Behcet's uveitis (P = 0.0001). Conversely, the B27/x genotype did not demonstrate significant associations with Behcet's uveitis. Furthermore, we employed prevalence-corrected positive predictive value (PcPPV) calculations to gauge the clinical utility of testing for these alleles within the Iranian Behcet's uveitis patient population. The PcPPV for B27/x genotype testing was determined to be 0.05%, while the PcPPV for B51:01/x genotype testing in the same population was 0.065%. These results suggest that carriers of the B*51:01 allele, when presenting with clinical symptoms, exhibit a heightened risk for Behcet's uveitis compared to the general population.
Conclusion
Individuals carrying the B51:01 allele, when symptomatic, face an elevated Behcet's uveitis risk. This insight aids in targeted clinical assessments for at-risk populations.

Objectives
Mutations in the α-galactosidase A (GLA) gene result in Fabry disease (FD), a rare metabolic condition. FD patients present with heterogeneous clinical manifestations, which may overlap with systemic diseases including familial Mediterranean fever (FMF). The aim of this study was to determine the frequency of FD in patients with mild and severe FMF and to prevent misdiagnosis by increasing clinicians’ awareness.
Methods
Based on Tel-Hashomer criteria, the study included a total of 91 FMF patients. Patients were divided into two groups according to the number of recurrent clinical episodes or failure to respond to maximum therapy: those with mild and severe forms of the disease. GLA gene mutations and α-GLA enzyme activity were assessed. Records of MEFV mutations, therapies and demographic characteristics were kept.
Results
FD testing was performed on a cohort of 91 FMF patients, 54.9% had mild FMF, 45.1% had severe FMF, and only one patient in the mild FMF subgroup tested positive for FD. The patient was a 39-year-old woman with a history of recurrent abdominal pain, distal limb pain and fever. She had low GLA enzyme activity and a heterozygous GLA gene mutation.
Conclusions
Our findings suggest that FD should be considered in the differential diagnosis of FMF, especially in individuals with unusual symptoms.

Evaluate response to treatment and progression to rheumatoid arthritis (RA) in patients with fibromyalgia (FM) associated with elevated rheumatoid factor (RF).
Material and methods
Prospective cohort study. The sample consisted of 124 patients with FM: 62 with high RF (> 20 U/ml) and 62 with negative RF (0-20 U/ml). All patients were evaluated using FM treatment improvement score (FIQR) and progression to RA according to EULAR/ACR 2010 criteria at 6 and 12 months. Pearson's χ2 test for homogeneity was used to relate variables of improvement to FM treatment and progression to RA.
Results
The response to treatment was lower in the high RF group (24 and 20 patients improved at 6 and 12 months, respectively, compared to 45 and 38 patients in the negative RF group), with a significant difference. Progression to rheumatoid arthritis was similar in both groups (5 in the high RF group and 4 in the negative RF group), with a non-significant relationship.
Conclusions
FM with elevated RF is associated with a poor therapeutic response but not with progression to RA.

Progression to rheumatoid arthritis was similar in both groups (5 in the high RF group and 4 in the negative RF group), with a non-significant relationship.</div></div><div><h3>Conclusions</h3><div>FM with elevated RF is associated with a poor therapeutic response but not with progression to RA.</div></div>","PeriodicalId":47115,"journal":{"name":"Reumatologia Clinica","volume":"20 9","pages":"Pages 459-462"},"PeriodicalIF":1.2,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142578915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
