Eight-year event-free survival (EFS) was evaluated in 205 patients with acute lymphoblastic leukemia (ALL), to consider the efficacy of high-dose methylprednisolone (HDMP) given during remission induction chemotherapy between 1 and 29 days. The St Jude Total XI Study protocol was used after some minor modifications in this trial. Patients were randomized into two groups. Group A (n = 108) received conventional dose (60 mg/m(2)/day orally) prednisolone and group B (n = 97) received HDMP (Prednol-L, 900-600 mg/m(2) orally) during remission induction chemotherapy. Complete remission was obtained in 95% of the 205 patients who were followed-up for 11 years; median follow-up was 72 months (range 60-129) and 8-year EFS rate was 60% overall (53% in group A, 66% in group B). The EFS rate of group B was significantly higher than of group A (P = 0.05). The 8-year EFS rate of groups A and B in the high-risk groups was 39% vs 63% (P = 0.002). When we compared 8-year EFS rate in groups A and B in the high-risk subgroup for both ages together =2 or >/=10 years, it was 44% vs 74%, respectively. Among patients in the high-risk subgroup with a WBC count >/=50 x 10(9)/l, the 8-year EFS was 38% in group A vs58% in group B. During the 11-year follow-up period, a total of 64 relapses occurred in 205 patients. In group A relapses were higher (39%) than in group B (23%) (P = 0.05). These results suggest that HDMP during remission-induction chemotherapy improves the EFS rate significantly for high-risk patients in terms of the chances of cure. 相似文献

In this paper, research based on 51 children with a positive antiglobulin test is presented. Eighteen of the children had acute anemia and 33 had chronic anemia. Two clinical patterns were distinguished: an acute transient type and a prolonged chronic type. Corticosteroid therapy was effective in all acute cases but its results were variable in the chronic cases. The acute form was more frequent in young children, while chronic autoimmune hemolytic anemia (AIHA) occurred mainly among children at puberty. In the chronic form of the disease, it was sometimes necessary to add immunosuppressive drugs and in two cases to perform a splenectomy. 相似文献

AIMS: Adiponectin seems to be an important modulator for metabolic and vascular diseases. We aimed to measure plasma adiponectin levels in type 2 diabetic patients and investigate any association with the severity of proteinuria. METHODS: 80 patients (mean age, 46.9 +/- 5.1 years; body mass index (BMI), 25.8 +/- 1.98 kg/m2) and 47 healthy volunteers (mean age, 46.1 +/- 5.5 years; BMI 26.74 +/- 2.23 kg/m2) were included. Plasma adiponectin concentration, insulin levels, homeostasis model assessment (HOMA) indices, calculated glomerular filtration rate (GFR), high sensitive C reactive protein (hsCRP) and biochemistry panel were determined in all subjects. The association between adiponectin concentration and proteinuria was evaluated. Additionally, the relationship between adiponectin and hsCRP and calculated GFR were also investigated. RESULTS: Adiponectin levels in patients were significantly lower than those of controls (n = 80; 8.76 +/- 4.50 microg/ml for patients, n = 47; 24.27 +/- 5.59 microg/ml for controls, p < 0.001). Plasma adiponectin levels in patients with proteinuria were significantly lower than those without proteinuria (n = 43; 6.81 +/- 2.82 microg/ml for proteinuria, n = 37; 11.98 +/- 3.32 microg/ml for no proteinuria, p < 0.001). There was a significant negative correlation between plasma adiponectin concentrations and the degree of proteinuria (r = -0.433, p < 0.001). There were also significant negative correlations between adiponectin concentrations and insulin levels as well as HOMA index in the patient group (r = -0.322, p = 0.004; r = -0.301, p = 0.032). Additionally there was a significant negative correlation between adiponectin and hsCRP levels in the patient group (r = -0.872, p < 0.001). CONCLUSION: The results show that adiponectin is lower in patients with type 2 diabetes and the levels are negatively correlated with the severity of proteinuria. 相似文献

We observed less severe symptoms in patients with chronic idiopathic thrombocytopenic purpura (ITP) than in patients with acute ITP with similar platelet counts. Thrombopoietin (TPO), soluble P-selectin, soluble P-selectin per platelet, and interleukin 6 (IL-6) were evaluated in children with ITP before treatment in 16 acute and 22 chronic cases and after treatment in 10 acute and chronic cases who received mega-dose methylprednisolone. The levels of IL-6, soluble P-selectin, soluble P-selectin per platelet, and platelet count were similar in acute and chronic ITP (P > 0.05) but TPO in acute ITP was higher than that of the patients with chronic ITP (P < 0.05). The posttreatment IL-6 and TPO declined (P < 0.05), but soluble P-selectin and platelet count increased (P < 0.05). Posttreatment soluble P-selectin per platelet levels were higher than the normal values (P < 0.05). These results suggest that IL-6, soluble P-selectin, and soluble P-selectin per platelet are not responsible for the milder symptoms in chronic than in acute ITP. Mega-dose methylprednisolone seems to keep the soluble P-selectin levels elevated. 相似文献

Although colchicine induced myopathy has been described in patients with chronic renal failure, colchicine induced myopathy with myotonia has been reported very rarely. A 49-year-old man with chronic renal failure was hospitalised for investigation of fatigue, malaise and severe pain in all extremities. He was on colchicine therapy for 5 months. Neurological examination showed mildly decreased sensation in a distal symmetric pattern in lower extremities, moderate proximal limb weakness, hyporeflexia and severe myalgia on palpation. No clinical evidence of myotonia was present. Laboratory studies showed elevated creatine phosphokinase (CK), lactic dehydrogenase (LDH), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. Electromyographic (EMG) findings were compatible with myopathy and abundant, widespread myotonic discharges were determined. Muscle biopsy was consistent with vacuolar myopathy. After withdrawal of colchicine, CK, LDH, AST and ALT levels were normalised and the symptoms were disappeared gradually. In conclusion, the detection of myopathic motor unit potentials with myotonic discharges on EMG in patients on colchicine therapy is an important finding and it is possible to suggest that this clue may lead to the invasive procedure of muscle biopsy unnecessary. 相似文献

Differentiation of myeloid leukemic cells to mature granulocytes by high-dose methylprednisolone (HDMP, 20-30 mg/kg/day) with a favorable antileukemic effect has previously been demonstrated in children with acute promyelocytic leukemia and acute myeloblastic leukemia (AML) M4. In the present study, three children with other morphological subtypes of AML (two AML M1, one AML M2) were given methylprednisolone (30 mg/kg/day) orally in a single dose. After a short-course (3 or 7 days) of HDMP treatment alone, a striking decrease in blast cells associated with an increase in maturing and abnormally nucleated polymorphonuclear-like cells some containing Auer rods were detected in all patients in peripheral blood or bone marrow smears. During HDMP treatment, in parallel to morphological improvements, marked increases in the percentage of cells expressing granulocytic antigen (CD15) were observed. The increase of CD15 expression on myeloid cells, together with the steady expression of CD34 and CD117 antigens in Casel(AML M1) , is suggestive of aberrant CD34 + CD117 + CD15 + cells, which may indicate the leukemic origin of the maturing myeloid cells. These results suggest that HDMP treatment may induce differentiation of myeloid leukemic cells in some children with different morphological subtypes of AML, and that the differentiation-inducing effect of HDMP should be explored in other malignant diseases. 相似文献

Abstract: Endothelial dysfunction is strongly linked to cardiovascular disease and outcome of patients with chronic kidney disease. We hypothesized that decreased inflammatory activity and increased adiponectin following transplantation could be one mechanism for a better endothelial health. Fifty-eight living donor kidney transplant non-diabetic recipients, 31 (23 male, 29 ± 5 yr) on cyclosporine A and 27 (10 male, 26 ± 5 yr) on tacrolimus immunsupression, were studied longitudinally. Visfatin, adiponectin, high sensitive C-reactive protein (hsCRP) levels, brachial artery flow mediated dilatation (FMD) and nitroglycerine mediated dilatation were measured before transplantation and on the 30th and 90th day after transplantation. Pre-transplantation visfatin, adiponectin and FMD values of patients were significantly higher than those of the controls (p < 0.001 for all). All values decreased significantly 30 and 90 d post-transplantation. Plasma visfatin and adiponectin, correlated negatively with FMD levels 90 d both before and after kidney transplantation (p < 0.001 for both). Endothelial function improved during the first month after transplantation, and the degree of improvement correlated to reductions in circulating visfatin, adiponectin and hsCRP levels. Of interest, the intracellular enzyme visfatin was the strongest predictor of FMD both before and after kidney transplantation and may thus reflect endothelial cell damage directly. 相似文献

BACKGROUND: We aimed to show the impact of leukodepletion on renal function in patients undergoing on-pump coronary revascularization. PATIENTS AND METHODS: Fifty patients awaiting elective on-pump coronary revascularization with normal preoperative cardiac functions and with plasma creatinine levels ranging between 1.5 and 2.0 mg/dL were prospectively randomized into two groups: on-pump CABG with (group A: n = 25) and without leukodepletion (group B, n = 25). Renal glomerular and tubular injury were assessed by urinary alpha glutathione s-transferase (GST), plasma creatinine, and blood urea nitrogen (BUN) levels. RESULTS: The patients consisted of 14 females and 36 males with a mean age of 57.6 +/- 5.3 years. In the leukodepletion group, the mean levels of creatinine, BUN and urinary GST were found to be decreased on the first, third and fifth postoperative days compared with the control group. There was no mortality. Three patients in the control group needed postoperative dialysis. CONCLUSION: Patients with renal dysfunction undergoing on-pump CABG surgery seem to benefit from leukodepletion as a measure to prevent tubular damage and renal impairment compared with a control group. 相似文献

Asymmetric dimethyl-arginine (ADMA), a residue of the proteolysis of arginine-methylated proteins, is a potent inhibitor of nitric oxide synthesis. The increased protein turnover that accompanies proteinuric secondary amyloidosis may increase circulating levels of ADMA, and this may contribute to endothelial dysfunction. We performed a cross-sectional study of 121 nondiabetic proteinuric patients with normal GFR (including 39 patients with nephrotic-range proteinuria and secondary amyloidosis) and 50 age-, sex-, and BMI-matched healthy controls. The proteinuric patients had higher levels of serum ADMA, symmetric dimethyl-arginine (SDMA), high-sensitivity C-reactive protein (hsCRP), and insulin resistance (homeostasis model assessment index) than controls. Compared with controls, brachial artery flow-mediated dilatation (FMD), serum L-Arginine, and the L-Arginine/ADMA ratio were significantly lower among proteinuric patients, suggesting greater endothelial dysfunction. When patients with secondary amyloidosis were compared with patients with glomerulonephritis who had similar levels of proteinuria, those with amyloidosis had higher ADMA and SDMA levels and lower L-Arginine/ADMA ratios and FMD measurements (P < 0.001 for all). Finally, even after adjusting for confounders, ADMA level correlated with both proteinuria and the presence of secondary amyloidosis, and was an independent predictor of FMD. We propose that ADMA synthesis may be increased in chronic kidney disease, especially in secondary amyloidosis, and this may explain part of the mechanism by which proteinuria increases cardiovascular morbidity and mortality. 相似文献
