OBJECTIVE: To determine levels of interleukin 10 (IL-10) and IgG subclasses in serum from 53 patients with primary Sj?gren's syndrome (SS). METHODS: Serum levels of IL-10 were measured using specific sandwich ELISA in 25 patients with "definite" SS, 28 with "possible" SS, and 32 healthy controls. Interferon-gamma (IFN-gamma) and transforming growth factor-beta1 (TGF-beta1) were also measured by immunoassays. Immunoglobulin classes, IgG subclasses, and C-reactive protein were measured by nephelometry. RESULTS: Circulating IL-10 was elevated in 25 patients. The increase reached significance in the group with possible SS (p = 0.03) versus controls. In the group with definite SS, IL-10 level was correlated with IgG1 level (p = 0.01, r = 0.67) and with focus score (p = 0.01). IFN-gamma was undetectable in most patients. TGF-beta1 was higher (not significantly) in possible SS than in definite SS. CONCLUSION: IL-10 is increased in SS and may account for the overproduction of IgG1 in the syndrome. High IL-10 in the absence of increased IgG1 in possible SS suggests that IL-10 may be necessary but not sufficient for IgG1 overproduction and that other factors are involved. Whereas the correlation of IL-10 level with focus score was expected, it is intriguing that IL-10 was more frequently increased in the incomplete (possible) form of SS than the complete (definite) form. Elevated IL-10 may characterize the lower stage of eccrine dysfunction and perhaps contributes to limiting its severity. 相似文献

Various alterations of aminoacidemia have been described during breast cancer. The aim of this study was first to establish the specific modifications of plasma-free amino acid concentrations by a comparative study of 19 patients with mammary tumors and 18 healthy volunteers, and, second, to determine the evolution of aminoacidemia after surgical tumor removal. Aminoacidemia was determined the day before (D0), and then five days, one month (M1), and six months after surgical removal of the tumor, and a single determination was performed in control subjects. Plasma levels (µmol/L) of serine and glutamate were higher in cancer-bearing women at D0 (respectively, 124 ± 3 and 68 ± 7) than in healthy volunteers (respectively, 110 ± 6 and 48 ± 5). Surgical tumor removal induced a normalization of aminoacidemia (in µmol/L at D5: serine: 114 ± 4; at M1: glutamate: 55 ± 6 Non Significant (NS) from values of healthy subjects). Among the various patterns reported for breast cancer, we confirm one of those described by Cascino in 1995, and we show that these levels revert to normal after tumor surgical removal. 相似文献

We described a 59-year-old male patient who underwent liver transplantation in 1989 for hepatocellular carcinoma (HCC) complicating hepatitis B virus (HBV) cirrhosis. In 2001 (12 years after liver transplantation), he developed a lung metastasis of HCC without intrahepatic recurrence and the resection was done. In July 2003, he was symptom free without any recurrence. HCCmetastasis can develop even after a very long time of liver transplantation. Many HCCs grow slowly, and the growth rate of recurrent tumors in patients receiving immunosuppressive therapy is significantly greater thanthat of those who do not receive immunosuppressive therapy. 相似文献

The objective of this study was to test whether increased resting energy expenditure (REE) in chronic obstructive pulmonary disease (COPD) patients is related to increased cost of breathing and/or to increased cytokine production.In 36 non-inflammatory (CRP: 17.6 +/- 13.1 mg.l(-1), mean +/- SD; orosomucoid: 0.71 +/- 0.18 g.l(-1)), non-malnourished (BMI: 23.6 +/- 4.3 kg.m(-2)), clinically stable, non severely hypoxic COPD patients (60.5 +/- 8.9 years) we measured REE, pulmonary function and plasma cytokine concentrations (TNF-alpha, IL1 and IL6). REE was increased by 10 +/- 11% (P< 0.001) above predicted values. Plasma TNF-alpha concentration was increased in all patients (mean value 26.3 +/- 14.3 pg.ml(-1)). Excess REE (with respect to values predicted by Harris-Benedict equations) was correlated with plasma TNF-alpha concentration (P< 0.005), but not with the degree of airway obstruction, lung overinflation, or with oxygen cost of breathing. Theophylline treatment resulted in a significant increase in REE by 15%.In conclusion: non-malnourished, clinically stable, non-severely hypoxic COPD patients display an increased REE that is related with plasma TNF-alpha concentration (without apparent systemic inflammation) and to theophylline treatment, but that is independent of parameters of respiratory function. 相似文献
