急性白血病患者血清可溶性肿瘤坏死因子受体水平及其临床意义

OBJECTIVE: To explore the levels of serum soluble tumor necrosis factor receptors (sTNFRs) and the relationships with clinical situation, chemotherapeutic effects and TNF alpha level in acute leukemia (AL) patients. METHODS: Serum levels of sTNFRs and TNF alpha were measured by ELISA. Six parameters which might influence therapeutic effects were analyzed by logistic regression. RESULTS: 1. Serum levels of sTNFR I and sTNFR II in 31 untreated AL patients were significantly higher than those in controls(P < 0.001 and < 0.005, respectively) and in bone marrow remission (BMR) AL patients (P < 0.005 and < 0.05, respectively). The levels of sTNFR I and sTNFR II in 11 relapsed/refractory AL patients were significantly higher than those in controls(P < 0.001 and < 0.05, respectively), but were not different from those in untreated AL patients. 2. Serum levels of sTNFR I in untreated ALL patients were significantly higher than those in ANLL patients (P < 0.05). 3. High levels of serum sTNFR I were more common in patients with high leukocyte count(> or = 100 x 10(9)/L) and high levels of serum sTNFR II were more common in patients with splenomegaly. Levels of the two sTNFRs positively correlated with blasts in peripheral blood (P < 0.001 and < 0.05, respectively). 4. The level of TNF alpha in 31 untreated AL patients significantly correlated with the level of sTNFR I (r = 0.440, P < 0.05). 5. The BMR rate was higher in those serum sTNFR I level < 2.0 micrograms/L than in those > or = 2.0 micrograms/L(P < 0.05). 6. Of the six parameters which might influence AL therapeutic effects, only sTNFR I < 2.0 micrograms/L was predictive. CONCLUSION: High levels of serum sTNFRs in AL patients might be derived from leukemic cells and predicted an adverse prognosis.     

白细胞介素-18与系统性红斑狼疮活动性关系探讨

Serum neopterin, tumor necrosis factor-alpha and soluble tumor necrosis factor receptor II (p75) levels and disease activity in Egyptian female patients with systemic lupus erythematosus

OBJECTIVE: To determine the clinical value of assaying serum levels of neopterin, tumor necrosis factor-alpha (TNF-alpha) and soluble tumor necrosis factor receptor II (p75) (sTNFRII) in patients with systemic lupus erythematosus (SLE), manifested clinically with lupus nephritis (LN), neuropsychiatric lupus erythematosus (NPLE), and/or vasculitis compared with established parameters (complements C3 and C4). PATIENTS AND METHODS: Serum concentrations of neopterin, TNF-alpha and sTNFRII were studied in 40 female patients with SLE at various degrees of disease activity and in 10 healthy controls, matched for age and sex, using an ELISA kit. Disease activity was assessed by the SLE disease activity index (SLEDAI) score. Thirty-five, 30 and 28 of our patients presented with LN, NPLE and/or vasculitis, respectively, as the main clinical manifestation. RESULTS: Serum levels of neopterin, TNF-alpha and sTNFRII were significantly increased, while the TNF-alpha/sTNFRII ratio, C3 and C4 levels of SLE patients were significantly lower than those of healthy controls. Neopterin and sTNFRII were the only parameters that showed significantly higher levels in SLE patients with mild activity compared to normal subjects and were the only parameters that showed a significant elevation in membranous nephritis and in mild NPLE compared to patients without nephritis and NPLE. Patients with vasculitis had significant elevation of serum neopterin, TNF-alpha and sTNFRII levels compared to patients without vasculitis. We found significant correlations between all measured variables and the SLEDAI score. Also, serum neopterin levels showed significant positive correlation with serum TNF-alpha, sTNFRII and TNF-alpha/sTNFRII levels. Serum neopterin and sTNFRII could be used to identify SLE patients from normals with a sensitivity and specificity of 100%. Multivariate linear regression analysis showed that serum sTNFRII was the only significant independent variable among parameters for prediction of SLE disease activity. CONCLUSION: We suggest that serum sTNFRII and neopterin are more sensitive markers of disease activity than TNF-alpha, C3 or C4. However, sTNFRII may be a clinically useful independent marker for prediction of SLE disease activity and to differentiate normal subjects from those having mild SLE.

Urinary N-acetyl-beta-D-glucosaminidase (NAG) in lupus nephritis and rheumatoid arthritis

Increased activity of urinary N-acetyl-beta-D-glucosaminidase (NAG) can be used as an early indicator of damage to the tubular epithelium. Systemic lupus erythematosus (SLE) is a multisystem autoimmune rheumatic disease. Nephritis is known as the most serious complication of SLE and the strongest predictor of poor outcome. In this study urinary NAG excretion was investigated in 24 SLE patients with normal renal function (serum creatinine < or =1.2 mg/dL) and the results were compared with those from 26 untreated patients with rheumatoid arthritis (RA) and 27 healthy controls. The SLE patients were divided into two groups according to their urinary total protein levels: group A consisted of 16 patients with < or =3.5 g/day proteinuria, and group B consisted of eight patients with nephrotic-range proteinuria (>3.5 g/day). Serum and urinary creatinine, total urinary protein levels, and urinary NAG excretion were measured in patients with SLE and RA. In addition, serum C3 and C4 levels were determined in the SLE patients. Renal biopsies were performed in all of the SLE patients. Glomerular lesions were classified according to WHO criteria for lupus nephritis (LN) I-V. The Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) was used to assess disease activity. Urinary NAG excretion was significantly higher in the SLE groups than in the healthy controls (P<0.001). In urinary NAG excretion there was also significant difference between SLE groups and RA patients (P<0.001). However, there was no significant difference in NAG excretion between the RA and control groups (P=0.062). Urinary NAG excretion was significantly higher (P<0.05) in group B compared to group A. There were no differences in SLEDAI scores, ages, and serum creatinine levels between study groups (P=0.601, P=0.285, P=0.669, respectively). Elevated SLEDAI values and hypocomplementemia were detected more often in younger patients (P<0.010, r=-0.529 and P<0.010, r=-0.569, respectively). There was a strong positive correlation between proteinuria and urinary NAG activity (P<0.001, r=0.759). These results suggest that the determination of urinary NAG activity may be a useful supplement to the routine biochemical analysis performed on the urine in cases of SLE.
