再生障碍性贫血患者细胞免疫指标的观察

采用酶免疫和放射免疫法分析了再生障碍性贫血(AA)患者外周血T淋巴细胞亚群、血清肿瘤坏死因子(TNF)、γ-干扰素(IFN-γ)和IL-2水平,以及患者外周血单个核细胞体外诱生的上述细胞因子水平。结果表明:患者CD4/CD8细胞比值降低或倒置(P<0.001),血清TNF和IFN-γ水平显著增高(P<0.01),外周血单个核细胞诱生的TNF、IFN-γ和IL-2水平均明显高于正常对照(P<0.01)。提示T淋巴细胞亚群比例失调和TNF、IFN-γ等造血负调控因子的过量分泌可能与AA的发病机制有关。     

慢性肾衰血透患者IL-1β、IL-6、TNF-α检测及意义

本文检测了93例慢性肾衰患者血透前后白细胞介素1β(IL-1β)、白细胞介素6(IL-6)、肿瘤坏死因子-α(TNF-α)含量。结果发现慢性肾衰患者IL-1β、TNF-α水平均显著高于正常对照组(p<0.01)。单次血透后IL-6水平显著升高(p<0.01),IL-1β水平有所下降。长期血透对IL-1β、IL-6、TNF-α诱生水平影响不大。提示慢性肾功能衰竭患者细胞免疫多方面功能受损,血透能部份纠正这些免疫学异常,但长期血透仍无助于改善慢性肾功能患者的免疫功能受损。

Tumour necrosis factor-alpha (TNF), lymphotoxin and TNF receptor levels in serum from patients with Wegener's granulomatosis

Wegener's granulomatosis (WG) is a systemic inflammatory disease with vasculitis as the key feature. Abnormal expression of tumour necrosis factor alpha (TNFalpha) is considered of prime pathogenic importance in several inflammatory diseases. The effects of TNFa are mediated by TNF receptors (TNF-R), and these receptors are often found in soluble forms (sTNF-R), which can modulate TNFalpha actions. To evaluate the clinical importance of the TNF family of cytokines, the serum levels of TNFalpha, TNFbeta, now termed lymphotoxin (LTalpha), and sTNF-R1 and sTNF-R2 were measured by ELISA in 8 patients with WG during active disease and during immunosuppressive treatment, and in 11 healthy controls in parallel. Serum concentrations of TNFalpha were undetectable in all except two controls (18%) and three patients with WG (37%). After 7 days of therapy, six of the WG patients had measurable TNFalpha levels. Examination of the relative amounts of TNFalpha and sTNF-R indicated that TNFalpha was mostly bound to its soluble receptors. In WG, the serum levels of sTNF-R1 and sTNF-R2 were dramatically increased (p<0.01), with little or no variation during treatment. While the IL-1beta levels did not deviate significantly from controls, the IL-1ra levels were significantly elevated in the WG patients throughout the study period (p<0.01).     

Pemphigus vulgaris: the role of IL-1 and IL-1 receptor antagonist in pathogenesis and effects of intravenous immunoglobulin on their production

Intravenous immunoglobulin (IVIG) is increasingly being used for the treatment of autoimmune diseases. In the present report, the role of IVIG on in vivo and in vitro production of IL-1 and IL-1 receptor antagonist (Ra) was studied in patients with pemphigus vulgaris (PV). Serum samples from 20 untreated patients with active PV prior to initiation of systemic therapy, 20 patients receiving IVIG treatment, 20 patients in clinical remission after conventional therapy, and 20 normal human controls were studied to determine the serum levels of IL-1alpha, IL-1beta, and IL-1Ra. The in vitro production of these cytokines was measured in the culture supernatant of peripheral blood mononuclear cells (PBMC) from 10 PV patients immediately before and after IVIG therapy and from age and sex-matched 10 healthy donors simultaneously. Elevated levels of IL-1alpha and IL-1beta were detected (i) in the serum of untreated PV patients with active disease prior to systemic therapy and (ii) before IVIG infusions in patients receiving IVIG therapy. These increased levels are statistically significant when compared to the levels in healthy controls (P < 0.01). A marked reduction of IL-1alpha and IL-1beta was detected (i) in the serum of patients in prolonged clinical remission and (ii) immediately after IVIG infusion in those patients on IVIG therapy. Increased level of IL-1Ra was detected in PV patients in prolonged clinical remission and after IVIG infusion in those receiving IVIG therapy. These differences were statistically significant when compared to the levels in normal controls and to the levels in the sera of patients with active disease (P < 0.01) or just before the beginning of IVIG infusion (P < 0.01). Similar differences in the levels of IL-1alpha, IL-1beta, and IL-1Ra were found in the culture supernatant of PBMC isolated from the PV patients pre and post IVIG therapy. These observations suggests that, compared to normal controls, patients with active PV have reversed levels of IL-1alpha, IL-1beta, and IL-1Ra. IVIG therapy may down-regulate production of IL-1alpha and IL-1beta and enhance production of IL-1Ra, in vivo and in vitro. This might be one of the important mechanisms by which IVIG produces its early therapeutic effects in pemphigus vulgaris.
