Takayasu’s arteritis occurring under TNF blockers in a patient with spondyloarthritis: is it an association or a paradoxical effect?

Coexistence of spondyloarthritis (SpA) and Takayasu’s arteritis is not a common finding, but such cases have been discussed, particularly in the context of choice of therapy. Inhibition of inflammation by tumor necrosis factor inhibitors (TNFi) is a key aspect of the treatment of SpA and also positive effects of such treatment in concomitant large vessel vasculitis have been reported. However, TNFi is also associated with the possibility of initiating vasculitis.The present article based on a case study and the available literature is an attempt to discuss coexistence of these two diseases and the impact of treatment with biological drugs from the anti-TNF group in the course of SpA with Takayasu’s arteritis.     

Direct anti-proliferative effect of adipose-derived mesenchymal stem cells of ankylosing spondylitis patients on allogenic CD4+ cells

ObjectivesT-cell-mediated adaptive immunity contributes to the development and persistence of ankylosing spondylitis (AS). Mesenchymal stromal/stem cells (MSCs) have immunomodulatory potential and are able to inhibit T-cell proliferation, but their functionality in AS patients is relatively unknown. The aim of the study was to assess the direct anti-proliferative effects of MSCs isolated from subcutaneous abdominal adipose tissue of AS patients (AS/ASCs) on allogeneic T lymphocytes, using commercially available ASC lines from healthy donors (HD/ASCs) as a control.Material and methodsCD3+CD4+ T-cells were isolated from peripheral blood of healthy blood donors, activated with anti-CD3/CD28 beads, and co-cultured for 5 days with untreated and TNF+IFN-γ pre-stimulated HD/ASCs (5 cell lines) and AS/ASCs, obtained from 11 patients (6F/5M). The proliferative response of T-cells was analysed by flow cytometry, while the concentrations of kynurenines, prostaglandin E2 (PGE-2), interleukin 10 (IL-10), and interleukin 1 receptor antagonist (IL-1Ra) were measured spectrophotometrically or using a specific enzyme-linked immunosorbent assay (ELISA).ResultsHD/ASCs and AS/ASCs similarly reduced the T-cell proliferation response, i.e. the percentage of proliferating cells, the proliferation, and replication indices, and these effects were dependent mostly on soluble factors. In the co-cultures of activated CD4+ T-cells with HD/ASCs and AS/ASCs significant increases of kynurenines, PGE-2, and IL-1Ra, but not IL-10, production were observed. The release of these factors was dependent either on cell-to-cell contact (IL-10, IL-1Ra) or soluble factors (kynurenines, PGE-2). There was a moderate to strong negative correlation between T-cell proliferative response, and the concentrations of kynurenines, PGE-2, and IL-10, but not IL-1Ra. This association was more evident in the case of TI-treated AS/ASCs than HD/ASCs.ConclusionsAS/ASCs, similar to HD/ASCs, exert a direct effective anti-proliferative impact on CD4+ T cells, acting via soluble factors that are released in cell contact-dependent (IL-10) and independent (kynurenines, PGE-2) pathways. Thus, our results suggest that AS/ASCs are potentially useful for therapeutic application.

全髋关节置换治疗强直性脊柱炎髋关节病变的研究进展

强直性脊柱炎是一种好发于青少年男性的血清阴性脊柱关节病，常见症状为腰骶僵硬和疼痛，晚期可发生脊柱强直和四肢大关节改变。自20世纪70年代采用人工全髋关节置换手术治疗强直性脊柱炎患者髋关节病变以来，现已逐渐成为其主要治疗方式。由于强直性脊柱炎患者髋关节局部及全身多系统病变的特殊性。其手术指征、手术方式、假体选择及对手术远期效果与手术并发症的预测仍存在争议。本文时国内外各项研究进展进行综述。

强直性脊柱炎并骨质疏松97例临床观察

研究强直性脊柱炎(AS)骨质疏松和骨量减少的发生情况、相关因素及与骨代谢指标的关系.选97例AS患者作为观察组,分别检测其血沉(ESR)、C-反应蛋白(CBP)、HLA-B27、血钙(Ca)、血磷(P)、碱性磷酸酶(ALP),并进行全身疼痛评分、中医症状积分评定和晨僵时间、BATH功能指数(BASFI)、病情活动指数(BASDI)、颌柄距、指地距、枕墙距、Schober试验、胸阔活动度、脊柱活动度;用双能X线法(DEXA)测定腰椎、股骨颈、股骨转子部、Ward's三角区骨密度(BMD),检测骨钙素(BGP)、降钙素(H-CT)、甲状旁腺激素(PTH);42例检测了尿脱氧吡啶啉(D-Pyr).选102名健康人作为对照组,分别测定其腰椎、股骨颈、股骨转子部、Ward's三角区骨密度(BMD),31例检测了BGP、PTH、D-Pyr、Ca、P、ALP.结果AS患者发生骨质疏松者42例(42.27%),骨量减少者36例(37.11%);AS患者BGP较对照组显著降低,并与腰椎、股骨近端BMD呈正相关.PTH、尿D-Pyr较对照组显著增高,并与股骨近端BMD呈负相关.AS患者中急时相反应物ESR与腰椎、股骨近端BMD呈显著负相关,CBP与AS患者腰椎、股骨颈、三角BMD呈显著负相关,ESR、CRP与尿D-Pyr呈显著的正相关.腰椎BMD与全身疼痛评分、中轴关节压痛指数呈负相关性,股骨近端BMD与指地距、BASFI、BASDAI呈显著负相关,与Schober试验、脊柱活动度呈显著正相关.AS患者的腰椎BMD与HLA-B27显示了负相关性.表明骨质疏松或骨量减少在AS中普遍存在,其发生与遗传、废用、免疫炎症等因素相关.AS患者骨代谢的失衡以骨生成的减少、骨吸收的增加为特点;PTH的增高及免疫炎性反应与AS患者骨吸收的增加有关.
