Abstract：

Objective To investigate the dynamic changes and the clinical significance of T-cell subsets and serum soluble interleukin-2 receptor (sIL-2R)in neonates with hyperbilirubinemia.Methods Thirty-one neonates with hyperbilirubinemia, admitted to the hospital from Decembr 1,2006 to January 31, 2007, were enrolled and divided into two subgroups: severe jaundice group and mild jaundice group according to the bilirubin level. Thirty-two age-mached healty newborns were as controls(control group Ⅰ). The T-cell subsets and sIL-2R of peripheral venous blood samples from these neonates were measured and compared. Sixteen of these 31 neonates with hyperbilirubinemiawere followed up and another twenty-six age-mached healty newborns were as controls(control group Ⅱ ). The level of serum bilirubin in convalescence of sixteen hyperbilirubinemia neonates and control group Ⅱ were tested and analyzed also. Results The levels of CD3, CD4, CD4/CD8 in the neonates with hyperbilirubinemia were lower compared with those of control group Ⅰ [(54.0±5.1)% vs (62.0±4.7)%, (26.8±5.0)% vs (43.0±4.7)%, 0.8±0.1 vs 1.4±0.2] (P＜0.01), but was higher in convalescence than in peak phase[ (62.4±3.3)% vs (55.1±4.2)%, (43.6±2.5)% vs (26.1±4.4)%, 1.4 ± 0.1 vs 0.8±0.1] (P＜0.01). The peak level of sIL-2R in the hyperbilirubinemia group was (319.4± 185.2) kU/L, higher than that in the convalescence [(129.7±99.3) kU/L] and in the control group Ⅱ [(171.9±102.2) kU/L] (P＜0.01). The serum bilirubin level showed negative correlation with CD4/CD8 ( r = -0.99, P ＜ 0.01 ) and positive correlation with sIL-2R (r=0.95, P＜0.05). The sIL-2R level was negatively correlated with CD4/CD8 (r=-0.92, P＜0.05). Conclusions Neonates, when suffering from hyperbilirubinemia, are immunosuppressed which may recover with the alleviation of jaundice.

Serum interleukin-2 and soluble interleukin-2 receptor in renal transplant recipients.

Interleukin-2 (IL-2) and soluble interleukin-2 receptor (sIL-2R), released during T-lymphocyte activation, were measured in serial samples of serum from 32 patients with renal allografts and other uremic patients. Patients undergoing chronic hemodialysis had elevated sIL-2R levels (1,801.93 +/- 753.23 U/mL) which dropped after stable renal transplantation (822 +/- 438 u/mL). However, these values were higher than those of a normal control group (397.3 +/- 84.5 u/mL, p < 0.01). Marked elevation of sIL-2R (1,503.78 +/- 640 u/mL) was noted in patients with acute rejection episodes compared to those in a stable allograft condition (p < 0.02) and those with cyclosporine nephrotoxicity (793.2 +/- 245.2 u/mL, p < 0.01), but returned to a stable level after successful anti-rejection treatment (745.91 +/- 345.8 u/mL, p < 0.01). Acute tubular necrosis and infection also showed a comparable rise in the sIL-2R level. The increase in sIL-2R with rejection was found one to four days earlier than the clinical diagnosis of acute rejection. There was a marked rise in the serum IL-2 level of uremic and post-transplant patients when compared to normal subjects (34.76 +/- 32.16 u/mL and 9.3 +/- 12.7 u/mL vs 4.38 +/- 3.38 u/mL, p < 0.001), but no significant differences were found between the IL-2 level of patients with acute rejection and cyclosporine nephrotoxicity or acute tubular necrosis (3.74 +/- 4.51 u/mL, 1.57 +/- 1.25 u/mL and 6.73 +/- 6.3 u/mL, p > 0.05). The diagnostic value of sIL-2R assay was more meaningful than that of IL-2.(ABSTRACT TRUNCATED AT 250 WORDS)     

The concentration of interleukin-2 and interleukin-2 soluble receptors in peritoneal fluid of patients with unexplained infertility

OBJECTIVES: We measured the concentration of interleukin-2 (IL-2) and interleukin-2 soluble receptor (sIL-2R) in peritoneal fluid (PF) of patients with unexplained infertility. MATERIALS AND METHODS: PF was obtained during laparoscopy from 7 women with unexplained infertility (UI) and 11 women with benign noninflammatory ovarian tumors. All laparoscopies were performed in follicular phase of the cycle. IL-2 and sIL-2R concentrations were measured in PF supernate stored in -70 degrees C until analysis using ELISA method (ENDOGEN). RESULTS: We found significantly (p = 0.009) lower concentration of sIL-2R in PF from patients with UI (303.844 U/ml) than in reference group (556.385 U/ml). The level of IL-2 was not detectable in 2 cases from women with UI and 5 cases from reference group. The concentration of IL-2 in PF did not differ (p = 0.135) between patients with UI (2.346 pg/ml) and those from reference group (1.064 pg/ml). CONCLUSIONS: The concentration of sIL-2R in PF of patients with UI was lower than in those from reference group. This may be the factor responsible for insufficient local immunosuppression, affecting reproduction.     

Human pregnancy serum inhibits proliferation of T8-depleted cells and their interleukin-2 synthesis in mixed lymphocyte cultures

T8-depleted and unfractionated T lymphocytes allogeneically stimulated and cultured in the presence of pregnancy sera exhibit an inhibition of cellular proliferation and interleukin-2 synthesis, respectively. Unfractionated T cells show a decrease in their cytotoxicity in the presence of these sera. The inhibition of cytotoxicity could be due to the deficit of IL-2 observed since if exogenous IL-2 is added to the cultures T4/LEU3a-depleted allogeneically stimulated cells reach the same degree of cytotoxicity whether cultured in normal human serum or pregnancy serum. A possible mechanism to explain the inhibition of mixed lymphocyte cultures by pregnancy serum could therefore be decrease of cellular proliferation of the T8-depleted subpopulation with a decrease in IL-2 synthesis, implying an inhibition of cytotoxic effector cells.     

Correlation between soluble Fas level and apoptosis of T cells in ovarian carcinoma

OBJECTIVES: The objectives were to examine the correlation between soluble Fas (sFas) level and apoptosis of T cells in peripheral blood and peritoneal fluid of patients with ovarian carcinoma and to investigate the possible sFas effect on T cell apoptosis. STUDY DESIGN: Patients with stages I-II ovarian carcinoma (n=10) and patients with stages III-IV ovarian carcinoma (n=22), as well as ovarian benign tumors (n=8), were enrolled in the study. Apoptosis of and Fas expression on T cells from peripheral blood and peritoneal fluids were assessed by flow cytometry. Soluble Fas level was assayed using an ELISA kit. The effects of peritoneal fluid on Jurkat cell apoptosis with or without depletion of sFas were evaluated and compared in vitro. RESULTS: The sFas level and apoptosis of T cells in peripheral blood and peritoneal fluid from stages III-IV ovarian carcinoma were significantly higher than those from stages I-II ovarian carcinoma (p<0.01 in all instances) and benign ovarian tumor (p<0.01 in all instances). In peritoneal fluid, the sFas level and apoptosis of T cells from stages I-II ovarian carcinoma were significantly higher than those from benign ovarian tumor (p<0.01 in all instances), and the Fas expression on T cells from ovarian carcinoma were higher than those from benign ovarian tumor (p<0.05 in all instances). There was a positive correlation between the sFas level and the apoptosis of T cells in peritoneal fluids from stages III-IV ovarian carcinoma (r=0.647, p=0.001). Peritoneal fluid of ovarian carcinoma could induce significant Jurkat cell apoptosis. The blocking of Fas expression on the Jurkat cell surface, but not the deletion of sFas, may remarkably restrain the apoptosis level. CONCLUSIONS: Elevated sFas is correlated with apoptosis of T cells in peripheral blood and peritoneal fluid from ovarian carcinoma. Soluble Fas evidently does not affect T cell apoptosis, which is probably due to elevated Fas expression on T cells.     

Elevated levels of interleukin-2, soluble interleukin-2 receptor alpha, interleukin-6, soluble interleukin-6 receptor and vascular endothelial growth factor in serum and ascitic fluid of patients with severe ovarian hyperstimulation syndrome

OBJECTIVE: To investigate the possible role of vascular endothelial growth factor, interleukin-2, soluble interleukin-2 receptor alpha, interleukin-6 and soluble interleukin-6 receptor in the pathogenesis of ovarian hyperstimulation syndrome. STUDY DESIGN: The study group consisted of 10 healthy women who developed severe ovarian hyperstimulation syndrome, group A (n=10), following ovarian stimulation by long GnRHa/hMG protocol for IVF. A control group B=10 patients underwent stimulation with the same protocol and did not develop OHSS. Blood and ascitic fluid samples were assayed for VEGF, IL-2, sIL-2Ralpha, IL-6 and sIL-6R by ELISA. RESULTS: The mean serum levels of IL-2, sIL-2Ralpha, IL-6, sIL-6R and VEGF in OHSS group were 297.5+/-190, 6588+/-5566, 40.6+/-16.6, 5280+/-3326 and 492+/-165 pg/ml as compared to 50.8+/-17.4, 1100+/-391.6, 8.5+/-3.5, 516+/-342 and 167+/-31.3 pg/ml in the control group, respectively, P<0.001. The mean ascitic fluid IL-2, sIL-2Ralpha, IL-6, sIL-6R and VEGF in the OHSS group were 282.5+/-191.5 pg/ml, 26020+/-13 995, 90.5+/-36, 14900+/-2789 and 660+/-359 pg/ml as compared to 32+/-14.8, 1206+/-429.4, 12.6+/-1.7, 614+/-240 and 151+/-20.5 pg/ml, respectively, P<0.001. CONCLUSIONS: The significantly high levels of VEGF in patients with severe OHSS suggest that VEGF is a major capillary permeability agent in OHSS. Elevated levels of IL-6 in serum and peritoneal fluid support the hypothesis that IL-6 may serve as a marker of OHSS. Although serum and ascitic fluid levels of IL-2 were elevated, accumulating evidence does not support a pivotal role for IL-2 in the pathogenesis of OHSS. However, it may have a peripheral role in mediating an increase in vascular permeability. Soluble IL-2Ralpha and sIL-6R may be considered to be involved in OHSS. However, the patho-physiologic mechanism is the subject of further investigations. Clinical application of VEGF-receptors in the management of OHSS is awaited with interest.

Serum soluble Fas levels in preeclampsia

OBJECTIVE: To determine if serum soluble Fas levels are altered in women with preeclampsia. METHODS: Thirty-four pregnant women with preeclampsia and 34 normotensive pregnant women were studied. Subjects were matched as much as possible for demographics. Preeclampsia was defined as proteinuric hypertension. Serum soluble Fas levels were measured by enzyme-linked immunoassay. Two-tailed Student t test, chi(2) test, Pearson correlation coefficients, and analysis of variance with post hoc test were used for statistical analyses. RESULTS: Mean serum soluble Fas levels were significantly higher in preeclamptic than normotensive women (10.59 +/- 0.68 U/mL versus 5.65 +/- 0.35 U/mL, P <.001). CONCLUSION: Elevated serum soluble Fas is associated with preeclampsia. Such elevation might indicate protection of maternal T-lymphocyte apoptosis and consequently lead to the maternal immune intolerance noted in preeclampsia.
