    ABSTRACT: Acute myeloid leukemia (AML) relapse is often associated with a poor outcome, especially after allogeneic stem cell transplantation (Allo-SCT). In patients relapsing early after SCT treatment, options are further limited by the fear for increased toxicity. We report our experience with ARA-C and gemtuzumab ozogamicin (GO) combination in relapsed post-SCT AML patients. Therapy consisted of ARA-C (1 gr/m(2)) for 4 days followed by one dose of GO 9 mg/m(2) on day 5 and was supported by donor stem cells when possible. Responding patients not developing graft versus host disease (GVHD) were eligible for immunotherapy with donor lymphocyte infusion (DLI) or a second Allo-SCT. Sixteen patients, median age 53 years (range 31-63), are included in this analysis. Patients underwent SCT for high-risk AML (n = 11) or AML relapse (n = 5), and 81 % had an early post-SCT relapse. Responses were achieved in 60 % of evaluable patients (CR-5 CRp-4). Median probabilities of survival (OS) and event-free survival (EFS) in the entire cohort, responding and non-responding patients were 103 and 76 days, 183 and 97 days, and 79 and 16 days, respectively. At 1-year follow-up, 25 % of patients were alive; however, all had relapse. Treatment resulted in grade 3-4 neutropenia and thrombocytopenia in all patients, and 27 % each had grade 3-4 hyperbilirubinemia or elevation of liver enzymes. One patient died during treatment due to intracranial hemorrhage. Of the six patients proceeding to second SCT or receiving DLI, three patients developed mild veno-occlusive disease (VOD). Combination therapy with ARA-C and GO after SCT results in short-term disease control and limited toxicity and could be considered for patients who are candidates for further immunotherapy.

    ABSTRACT: Decreased spleen and liver volumes and increased hemoglobin levels and platelet counts usually occur with enzyme replacement therapy (ERT) in symptomatic patients with Gaucher disease. Because of decreased supply of imiglucerase, an FDA-approved Early Access Program (EAP) allowed use of a new, pre-licensed ERT, velaglucerase alfa. This report provides safety and efficacy findings in patients on EAP velaglucerase alfa who completed 6, 9, or 12 months as intravenous every-other-week ERT. EAP was approved by the Israeli Ministry of Health. All patients enrolled in the EAP were included for safety measures; only those with >6 month evaluations of hemoglobin, platelet counts, and liver and spleen volumes were included for efficacy. Descriptive statistics were employed. Among 71 EAP patients, there were no drug-related serious adverse events or withdrawals; one patient (1.4%) with previous hypersensitivity to a different ERT had a drug-related allergic reaction. Of 44 patients with appropriate time-period evaluations, 8 patients were treatment-naïve and responded well to velaglucerase alfa. The 36 switch-over patients remained at imiglucerase low-doses; a majority of patients showed improvements in each efficacy parameter. Switch-over from imiglucerase (10-224 months) was safe and in several patients velaglucerase alfa induced a booster-effect.

    ABSTRACT: This is a case series and literature review of patients with various types of hematologic disorders and sarcoidosis. The patients were treated in the hematologic day care unit at Shaare Zedek medical center and at the hematology department of Chaim Sheba Medical Center hospital from 1990 until 2008. We report eight cases from two centers where both diseases were diagnosed at different time points. We have shown that there might be coincidence of two rare conditions and emphasize the importance of tissues sampling of lesions suspected to be a relapse of a former biopsy-proven disease, even in the presence of positive PET results.

    ABSTRACT: Moraxella is an aerobic, oxidase-positive, Gram-negative coccobacillus, which is rarely associated with serious and invasive infections. We describe 4 cases of Moraxella lacunata endocarditis and review 12 previously published cases of Moraxella endocarditis, including 1 further case with M. lacunata, 5 with M. catarrhalis, 2 with M. phenylperuvica and the remainder consisting of 1 case each of M. liquefaciens, M. osloensis, M. nonliquefaciens and 1 non-specified. Of these 16 patients, 5 had prosthetic valves, 5 suffered from an underlying heart abnormality, and the other 6 had normal hearts. Therapy consisted of a beta-lactam antimicrobial and, in several instances, an aminoglycoside as well. The mean duration of antibiotic treatment was 35+/-13 d. Four patients (25%) underwent surgery and 4 out of 16 (25%) died. Moraxella should be added to the growing list of organisms which may occasionally cause infective endocarditis, even in patients without preexisting valvular abnormality.

    ABSTRACT: 3 patients with vitamin B12 deficiency are described (men aged 64 and 67 and a women of 75). All presented with neurological disease; 2 had had severe weight loss. In 1 neither anemia nor macrocytosis was found, while in 2 there was only mild macrocytic anemia, so that the diagnosis was established quite late during the disease. These patients demonstrate that a high index of suspicion is required to diagnose vitamin B12 deficiency when there are only mild or no hematological abnormalities. This is especially important because of the direct relation between time elapsed before therapy and the irreversibility of neurological damage. Of note is the severe weight loss simulating malignant disease that can be the presenting symptom or appear during the course of the disease.
