Pre-Emptive Immunotherapy for Clearance of Molecular Disease in Childhood Acute Lymphoblastic Leukemia after Transplantation

2016

Abstract Monitoring of minimal residual disease (MRD) or chimerism may help guide pre-emptive immunotherapy (IT) with a view to preventing relapse in childhood acute lymphoblastic leukemia (ALL) after transplantation. Patients with ALL who consecutively underwent transplantation in Frankfurt/Main, Germany between January 1, 2005 and July 1, 2014 were included in this retrospective study. Chimerism monitoring was performed in all, and MRD assessment was performed in 58 of 89 patients. IT was guided in 19 of 24 patients with mixed chimerism (MC) and MRD and by MRD only in another 4 patients with complete chimerism (CC). The 3-year probabilities of event-free survival (EFS) were .69 ± .06 for …

MR imaging of pancreatic changes in patients with transfusion-dependent beta-thalassemia major.

1999

The aim of this study was to evaluate MR imaging changes of the pancreas in patients with transfusion-dependent beta-thalassemia major.Twenty patients with transfusion-dependent beta-thalassemia major were examined using MR imaging at 0.5 T, with spin-echo T1-weighted, fast spin-echo T2-weighted, and gradient-echo T2*-weighted sequences. Image analysis was performed to assess pancreas-to-fat signal intensity ratios for all pulse sequences. Pancreatic exocrine and endocrine function and serum ferritin levels were assessed. Twenty healthy volunteers underwent MR imaging with the same three sequences and served as a control group.The pancreas-to-fat signal intensity ratio was significantly dec…

Transfusional Hemochromatosis: Quantitative Relation of MR Imaging Pituitary Signal Intensity Reduction to Hypogonadotropic Hypogonadism

2000

To assess the relationship between magnetic resonance (MR) imaging pituitary signal intensity reduction in patients with transfusional hemochromatosis and the clinical manifestation of hypogonadotropic hypogonadism.Pituitary MR imaging at 0.5 T was performed in 38 consecutive patients affected by secondary hemochromatosis and in 20 healthy volunteers. Serum ferritin levels were estimated in the affected population. Twenty (53%) of the 38 patients had hypogonadotropic hypogonadism diagnosed. Pituitary-to-fat signal intensity ratios were calculated from coronal gradient-echo (GRE) T2*-weighted MR images. The relationship between the quantitative reduction of the pituitary-to-fat signal intens…

Autologous whole blood injections to patients with chronic urticaria and a positive autologous serum skin test: a placebo-controlled trial.

2005

<i>Background:</i> Patients with chronic urticaria (CU) frequently exhibit positive skin test reactions to autologous serum (ASST). Therapies aimed at inducing tolerance to circulating histamine-releasing factors in ASST+ CU patients, e.g. by treatment with autologous whole blood (AWB), have not yet been tested. <i>Objective:</i> To test whether ASST+ CU patients can benefit from repeated low-dose intramuscular injections of AWB. <i>Methods:</i> We characterized CU severity and duration, anti-Fc<sub>Ε</sub>RI and anti-IgE expression, use of antihistamines, and quality of life in 56 CU patients (ASST+: 35, ASST–: 21) and assessed the t…

Failure of sustained engraftment after non-myeloablative conditioning with low-dose TBI and T cell-reduced allogeneic peripheral stem cell transplant…

2001

We investigated whether a T cell-reduced allogeneic stem cell transplant (SCT) with minimal conditioning and subsequent donor lymphocyte infusions (DLI) could reduce the incidence and severity of GVHD while retaining stable engraftment. Five patients with hematological malignancies (three MM, one CLL, one Chediak-Higashi syndrome) were conditioned with TBI (200 cGy). One patient additionally received fludarabine (120 mg/m(2)). CsA and mofetyl-mycophenolate (MMF) were administered to prevent GVHD. All patients were grafted with >3 x 10(6)/kg highly purified CD34(+) cells together with 2 x 10(6)/kg CD3(+) cells (three patients) or 1 x 10(5)/kg CD3(+) cells (two patients). Quick hematopoietic …

A complication risk score to evaluate clinical severity of thalassaemia syndromes

2020

The thalassaemia syndromes (TS) show different phenotype severity. Developing a reliable, practical and global tool to determine disease severity and tailor treatment would be of great value. Overall, 7910 patients were analysed with the aim of constructing a complication risk score (CoRS) to evaluate the probability of developing one or more complications. Nine independent variables were included in the investigation as predictors. Logistic regression models were used for Group A [transfusion-dependent thalassaemia (TDT)], Group B [transfused non-TDT (NTDT)] and Group C (non-transfused NTDT). Statistically significant predictors included age (years), haemoglobin levels, hepatic transaminas…

Use of topical tranexamic acid in primary total hip arthroplasty. Efficiency and safety. Our experience.

2019

Abstract Background and aim Intravenous tranexamic acid has been shown to reduce bleeding and the need for transfusions in total hip arthroplasty, although it has a theoretical risk of producing thromboembolic phenomena. Recently some papers have been published using the topical application of tranexamic acid, but the ideal administration protocol has not yet been clearly defined. The aim of this paper was to demonstrate that our protocol of topical tranexamic acid is effective and safe. Methods Prospective data collection from a case series of 80 primary hip arthroplasties, in which the following topical tranexamic acid protocol is used: 1.5 g diluted to a total volume of 60 ml were admini…
