Prognostic significance of serial determinations of lactate dehydrogenase (LDH) in the follow-up of patients with myelodysplastic syndromes.

Background: Early recognition of disease progression in low-risk myelodysplastic syndromes (MDS) is an important decision point concerning intensive therapies. In a screen program searching for dynamic prognostic determinants, we have identified lactate dehydrogenase (LDH) as a most suitable follow-up parameter.

Patients And Methods: LDH levels were serially determined in 221 patients with de novo MDS (median age 70 years, range 24-94).

Pharmacokinetics of teicoplanin during continuous hemofiltration with a new and a 24-h used highly permeable membrane: rationale for therapeutic drug monitoring-guided dosage.

Objective: Continuous venovenous hemofiltration (CVVH) is widely used in the management of critically ill patients, but only few administration guidelines for antimicrobial drugs are available. It is unclear whether the use of a filter for more than 24 hours might lead to less efficient extraction. This study describes the pharmacokinetics of teicoplanin during CVVH using a highly permeable membrane.

A novel effective and safe consolidation for patients over 60 years with acute myeloid leukemia: intermediate dose cytarabine (2 x 1 g/m2 on days 1, 3, and 5).

Purpose: High-dose intermittent cytarabine is an effective postremission treatment for patients with acute myeloid leukemia (AML). This regimen is a safe approach in patients < 60 years but produced severe neurotoxicity in the elderly.

Experimental Design: We have established a dose-reduced age-adapted consolidation using intermediate dose (IDAC; 2 x 1 g/m(2) i.

The immunophenotype of 325 adult acute leukemias: relationship to morphologic and molecular classification and proposal for a minimal screening program highly predictive for lineage discrimination.

Bone marrow cells of 325 adults with acute leukemia were immunophenotyped using a panel of monoclonal antibodies proposed by the European Group for the Immunological Characterization of Leukemias (EGIL). Of these, 97.2% could be assigned clearly to myeloid or lymphoid lineage (254 acute myeloid leukemias [AMLs], 48 B-cell lineage acute lymphoblastic leukemias [ALLs], 14 T-cell lineage ALLs), 1.

Clearance of ceftazidime during continuous venovenous haemofiltration in critically ill patients.

Published recommendations for the optimal dosing regimen of ceftazidime in critically ill patients with continuous venovenous haemofiltration (CVVH) differ. The aim of this prospective study was to analyse the pharmacokinetic and pharmacodynamic parameters of ceftazidime during CVVH with a high-flux polysulphone membrane, and derive a dosage recommendation. Twelve critically ill patients (five female, seven male) with acute renal failure undergoing CVVH using a 0.
