Renal function tests (cystatin C, serum and urine creatinine, creatinine clearance, serum and urine 2-microglobulin, microalbuminuria, osmolality) were performed in 21 children at the diagnosis and during the treatment for acute lymphoblastic leukemia (ALL) (group I) and in 37 children (group II) treated for ALL 3.9±3.7 years before the study. The results were compared to 20 healthy children. Mean values of renal tests were in normal range at all points of analysis in groups I and II compared to the control group. Transitory higher cystatin C values (but in normal range) were observed after methotrexate administration and after the end of treatment. Deteriorated renal function was observed in one child during the treatment (after each protocol) and in five children treated previously for ALL. In conclusion, combined treatment for ALL is not associated with severe or long-term impairment of renal function. 相似文献

A 5-year-old African-American male was diagnosed with nephrotic syndrome (NS). Because of concomitant leukopenia, bone marrow aspiration was performed, which did not demonstrate a hematological malignancy. The patient received standard daily steroid therapy for treatment of NS. Steroid resistance at 5 weeks of therapy led to a renal biopsy, which documented focal segmental glomerulosclerosis (FSGS). He was begun on cyclosporin A (CsA) and later switched to tacrolimus because of side-effects of CsA. Seven months after the initial diagnosis of NS, the patient was diagnosed with acute lymphoblastic leukemia (ALL). The patient is in complete remission of ALL and partial remission of NS with continued nephrotic-range proteinuria. Review of the literature shows four other cases of pediatric ALL after NS. No particular immunosuppressive agent seemed to be causative in the evolution of ALL. Although the exact mechanism for development of ALL after NS is unknown, the incidence of leukemia may be increased after immunosuppressive therapy when used in this context. 相似文献

A 3.5-year-old girl with fever had a pancytopenic blood smear that also showed schistocytes and blast cells. Bone marrow examination
resulted in a diagnosis of acute lymphoblastic leukemia (ALL). Although creatinine on admission was normal, she had mild hematuria
and moderate proteinuria. Chemotherapy was started, but she was initially given only steroids (dexamethasone) due to high
liver enzymes. Her renal parameters worsened, and her creatinine doubled. She also developed nephrotic-range proteinuria and
hypertension. Renal biopsy showed thrombotic microangiopathy that was clinically consistent with hemolytic uremic syndrome
(HUS). Some reports of HUS preceding ALL do exist. However, to the best of our knowledge, this is the first case that describes
ALL and HUS presenting simultaneously. 相似文献

Osteonecrosis (ON) is a disabling complication of acute lymphoblastic leukemia (ALL) treatment in children and young adults. Isolated talus involvement is thought to be uncommon. A unique case of a 11-year-old female patient with ON in her left talus which developed six months after the completion of chemotherapy that she received for ALL is reported. A conservative treatment protocol was followed including activity modification, analgesia and prevention of weight-bearing. However, the disease significantly progressed during follow-up period. The present study makes an important contribution to the literature with unusual involvement pattern and location of ON after ALL treatment and with a long follow-up duration.Level of evidenceIV. 相似文献

The Authors describe the case of a 14-year-old girl who developed a multifocal osteonecrosis (ON), after treatment with chemotherapy
and corticosteroids for acute lymphoblastic leukemia (ALL). She came to our attention about 6 months after the beginning of
treatment complaining of pain in her left knee and later in both hips and shoulders. Radiography and MRI confirmed the presence
of avascular ON at all these sites. The patient underwent bilateral total hip arthroplasty, which was still functioning well
at the last follow-up visits at 5 years, and at 5 years and 4 months. ON is increasingly recognized as a complication of the
treatment of cancer in children and adolescents, and as patients now frequently survive ALL into adulthood, orthopedists will
be increasingly called on to manage this complication affecting multiple joints in children and young adults. 相似文献

Neutropenic enterocolitis (NE) is a life-threatening complication most commonly seen in patients receiving intensive chemotherapy for acute leukemia. The condition usually affects the terminal ileum, cecum, or ascending colon. In rare instances, NE may occur before the initiation of chemotherapy or involve more distal bowel. The authors report the case of a 2-year-old girl who had NE affecting the descending colon as a presenting complication of acute lymphoblastic leukemia. Despite aggressive medical interventions, including granulocyte infusions, she had a delayed bowel perforation that was managed successfully with surgery. This case highlights the challenges of treating patients who have NE as an initial manifestation of acute leukemia. 相似文献

Methods All 32 patients with Ph+ ALL achieved hematologic complete remission (CR) at time of transplantation, including 27 cases in the first CR (CR1) and 5 in CR2. Nineteen patients achieved molecular remission (MR). Among 32 patients, 4 received autologous HSCT (AHSCT), and 28 allogeneic HSCT (allo-HSCT). The conditioning regimens comprised of total body irradiation (TBI), cyclophosphamide, fludarabine and cytarabine. The median number of transfused mononuclear cells was 5. 6 × 108/kg, and that of CD34+ cells was 2. 94 × 106 /kg. Thirty-one patients were administrated imatinib orally before transplantion, at a dose of 400~600 mg/day, and 16 patients after transplantation, including 7 for prevention at a dose of 300~400 mg/day and 9 for salvage treatment at a dose of 400 ~ 600 mg/day. Results Hematopoietic reconstitution was achieved in all 32 patients. Three-year estimate of overall survival (OS) was (62. 1±8. 6)%, leukemia-free survival (LFS) (59. 2 ± 8. 7)%, relapse rate (RR) (17. 7 ± 7. 2)% and transplant-related mortality (26. 2 ± 8. 0) %. All 4 undergoing AHSCT were alive, and 3 out of them were in continuous CR with durations of 14, 18 and 67 months respectively. The univariate analysis for prognosis in allo-HSCT showed that the OS of HLA-matched sibling donors group was 76. 5 %,higher than that of unrelated or haploidentical donors group (27. 3 %, P<0. 05), and so was LFS (70. 6 % vs 27. 3 %, P<0. 05). RR in patients achieving MR at time of transplantation was 5. 6 %,lower than that in those not achieving MR (40. 0 %, P<0. 05). RR in patients in CR1 at time of transplantation was 12. 5 %, lower than that in those in CR2 (50 %, P <0. 05). Conclusion Imatinib improved the outcomes of HSCT for Ph+ ALL, especially to patients achieving MR at time of transplantation and transplantation in early stage (CR1). 相似文献

Background
The aim of this study was to describe the spectrum of disease in children with acute pancreatitis and assess predictors of severity.Methods
Children (≤18 years) admitted to a single institution with acute pancreatitis from 2000 to 2009 were included. The accuracy of the Ranson, modified Glasgow, and pediatric acute pancreatitis severity (PAPS) scoring systems for predicting major complications was assessed.Results
The etiology of pancreatitis in these 211 children was idiopathic (31.3%), medication-induced (19.9%), gallstones (11.8%), trauma (7.6%), transplantation (7.6%), structural (5.2%), and hemolytic-uremic syndrome (3.3%). Fifty-six patients (26.5%) developed severe complications. Using the cutoff thresholds in the PAPS scoring system, only admission white blood cell count more than 18,500/μL (odds ratio [OR], 3.1; P = .010), trough calcium less than 8.3 mg/dL (OR, 3.0; P = .019), and blood urea nitrogen rise greater than 5 mg/dL (OR, 4.1; P = .004) were independent predictors of severe outcome in a logistic regression model. The sensitivity (51.8%, 51.8%, 48.2%) and negative predictive value (83.2%, 83.5%, 80.5%) of the Ranson, modified Glasgow, and PAPS scores were, respectively, insufficient to guide clinical decision making.Conclusion
Commonly used scoring systems have limited ability to predict disease severity in children and adolescents with acute pancreatitis. Careful and repeated evaluations are essential in managing these patients who may develop major complications without early signs. 相似文献14.

Purpose
Acute compartment syndrome (ACS) of the upper extremity is a rare but serious condition. The purpose of this study was to determine the etiology, diagnosis, treatment, and outcome of ACS of the upper extremity in a pediatric population.Methods
We performed a retrospective chart review of all patients who underwent a decompressive fasciotomy for ACS of the upper extremity. Data collected included demographics, injury details, presenting symptoms, compartment measurements, time to diagnosis, time to treatment, and outcomes at the latest follow-up.Results
Twenty-three children underwent fasciotomies for ACS of the forearm (15) and hand (8), at an average age of 9.3 years (range 0–17.8 years). The most common etiologies were fracture (13) and intravenous (IV) infiltration (3). The most common presenting symptoms were pain (83 %) and swelling (65 %). Compartment pressures were measured in 17/23 patients, and all but two patients had at least one compartment with a pressure >30 mmHg. The final two patients were diagnosed and treated for ACS based on clinical signs and symptoms. The average time from injury to fasciotomy was 32.8 h (3.7–158.0 h). Long-term outcome was excellent for 17 patients (74 %) and fair for 5 (22 %), based on the presence of loss of motor function, stiffness, or decreased sensation. One patient with brachial plexus injury and poor baseline function was excluded from functional outcome scoring. There was no association between the time from diagnosis to fasciotomy and functional outcome at the final follow-up (p = 1.000).Conclusions
Although ACS of the upper extremity in children is often associated with a long delay between injury and fasciotomy, most children still achieve excellent outcomes. The majority of patients presented with pain and at least one additional symptom, but treatment was often delayed, implying that ACS of the upper extremity in children is a difficult diagnosis to establish and may be associated with a prolonged clinical time course. 相似文献19.
