Morganella morganii causing fatal sepsis in a platelet recipient and also isolated from a donor's stool.

Bacterial contamination of blood products causes significant patient morbidity and mortality. Contaminated platelet transfusion is a frequent cause of bacteraemia and sepsis because of the storage conditions of platelets. A fatal case of Morganella morganii platelet transfusion associated with sepsis is described, along with procedures traced back to the isolation of M. morganii from a donor's stool. Molecular typing was performed, and the same M. morganii strain was found in blood and post-mortem organ cultures of platelet recipient and platelet bag and in the donor's stool. The route of contamination is unknown. The contamination could be due to either insufficient venipuncture site disinfection or the donor's transient bacteraemia. Patient died 5 days after the transfusion.

Long-term results of conventional-dose salvage chemotherapy in patients with refractory and relapsed Hodgkin's disease (Croatian experience).

BACKGROUND: The aim of this study was to analyze outcome of patients with Hodgkin's disease (HD) in whom first-line chemotherapy with mustine/vincristine/procarbazine/prednisone (MOPP) had failed. PATIENTS AND METHODS: From January 1982 to December 1989 among 210 patients treated with MOPP and radiotherapy to initial bulky sites, 65 patients were primary refractory to or relapsed after initial treatment. RESULTS: Twenty-nine of 65 patients (44%) were primary refractory to initial chemotherapy, 20 relapsed within 12 months after complete remission (CR) and 16 relapsed after CR that lasted more than 12 months. Patients with primary refractory HD and early relapse (<12 months after CR) were treated with doxorubicin/bleomycin/vinblastine/darcarbazine. In patients with late relapse (>12 months after CR) MOPP was repeated. The median follow-up for all patients was 115 months. The overall response rate was 63%. Thirty-three patients (51%) achieved a second CR and eight patients (12%) partial response. Remission rate was greatest in patients with late relapse (CR >12 months) (75 versus 55% for early relapse versus 35% for primary refractory HD) (P <0.01). At 10 years, overall and failure-free survival rates were 21 and 16%, respectively. Patients who were in first remission longer than 12 months had a superior overall survival (37 versus 18% for early relapse) and failure-free survival (24 versus 10% for early relapse). No patient with primary refractory HD was alive beyond 52 months after initial treatment failure (P <0.01). Main prognostic factors were duration of the first remission and tumor bulk at relapse. CONCLUSIONS: Our results confirm previous observations that a significant proportion of patients with HD who experience induction treatment failure cannot be cured with conventional treatment and probably need more aggressive therapy.

Trastuzumab in the treatment of advanced breast cancer: single-center experience.

A significant number of women with advanced breast cancer fail to respond to standard-dose chemotherapy. From the beginning of 1999, 17 women with HER2 positive advanced breast cancer received Herceptin as monotherapy or in combination with paclitaxel or other non-anthracyclines. Eight (47%) women previously received high-dose chemotherapy followed by haematopoiesis stem cell rescue. Three women received Herceptin alone, eleven Herceptin plus paclitaxel and three Herceptin and some of the other non-anthracyclines (CCNU, cisplatin and gemcitabine). In the group of patients who received Herceptin monotherapy, one has partial response (PR), one stable disease (SD) and in the third patient the disease progressed. Out of three patients who received Herceptin in combination with other non-anthracyclines, two have SD and one progressed. In the group of 11 women who received Herceptin + Taxol, 7 (64%) patients achieved PR, 2 (18%) SD, and 2 (18%) had disease progression. Grade 3-4 neutropenia has been observed in four (23%) women. Febrile neutropenia was observed in two cases and resolved completely when antibiotics were introduced. Other grade 3 toxicity that has been noted is peripheral neuropathy in three (18%) patients, diarrhoea in four (23%) and onycholysis in one (6%). Serial heart ultrasound showed no significant decline in left ventricular ejection fraction. According to our preliminary experience, Herceptin therapy showed promising results in women with metastatic breast cancer.

Treatment of chronic myeloid leukemia in relapse after umbilical cord blood transplantation.

Umbilical cord blood (UCB) is increasingly used as a source of hematopoietic progenitor cells for allotransplantation. Donor-derived buffy coat cells are considered optimal treatment for leukemia relapses after transplantation of allogeneic bone marrow. Experience with relapses after UCB transplants are sparse. Here we report a girl who received an UCB transplant for chronic myeloid leukemia, relapsed after three years, failed to respond to donor buffy coat cells, but achieved a complete hematologic, cytogenetic, and molecular remission on interferon-alpha.

Allogeneic bone marrow transplantation for acute leukaemia--IGCI experience. International Group for Chemo-Immunotherapy.

From October 1984 to December 1994, 142 patients from six IGCI-BMT centers (78 acute myelogenous leukemia and 64 acute lymphoblastic leukemia) received allogeneic bone marrow from their HLA-identical sibling. The probability of LFS at 60 months is 41% for AML patients and 39% for ALL patients. A better LFS was documented in patients allografted in first CR compared to the patients treated in advanced stage of the disease. The overall relapse rate is 27% for AML patients and 45% for ALL patients. The relapse rate is higher for patients allografted in advanced stage of the disease (47 vs 26% at 60 months for AML and 55 vs 38% at 60 months for ALL). The incidence of moderate to severe acute GVHD is between 45-50% for both AML and ALL patients. Chronic GVHD was documented in 30% of AML patients and 38% of ALL patients. Transplant-related mortality for both AML and ALL is about 25%. Relapse and GVHD with or without infection are the main causes of death. These results confirmed that allogeneic BMT is very effective therapy for patients with acute leukemia, especially for patients transplanted in first CR.

Anxiety as a possible predictor of acute GVHD.

In order to determine the influence of anxiety on the development of BMT complications and survival, we analysed data on 35 consecutive patients undergoing BMT in our Centre between June 1992 and December 1994. All patients received bone marrow from HLA-identical MLC non-responsive siblings. For GVHD prophylaxis, all patients received cyclosporin (CsA) and short methotrexate (MTX). The diagnosis and severity of acute GVHD were defined according to the Seattle Transplant Team criteria. The patients were tested with the Spielberger STAI test as a measure of anxiety as a state (STAI-S) and as a trait (STAI-T). The STAI-S/1 and STAI-T/1 were performed during the first week of isolation (day -5 to day -3 prior BMT) and STAI-S/2 and STAI-T/2 at the end of the discharge from laminar air flow units (day +35 to day +40 post-transplant). During isolation all patients had daily psychiatric support. Out of 35 patients, 31 (89%) fulfilled the STAI-S and STAI-T during the first week and at discharge from laminar air flow isolation. The level of anxiety at the beginning of isolation as measured by STAI-S/1 and STAI-T/1 tests had been significantly higher in patients who subsequently developed acute grade II-IV GVHD as compared to patients with GVHD grade 0-I (P < 0.001), irrespective of age, sex or stage of the disease prior to BMT. In those patients who died, the STAI-S/1, STAI-T/1 and STAI-T/2 tests had been almost identical to those of surviving patients, while STAI-S/2 had been significantly higher (P = 0.034). These data clearly indicate an association between the level of anxiety and the risk for BMT complications, but this should be confirmed in further controlled clinical trials.

An autopsy study of systemic fungal infections in patients with hematologic malignancies.

The aim of this study was to determine the incidence of fungal infections detected on autopsy in a group of 40 patients with hematologic malignancies treated with intensive chemotherapy or bone marrow transplantation, and to evaluate the risk factors for fungal infections. A control group included 38 patients with nonhematologic diseases and without granulocytopenia but with at least one of the known risk factors for fungal infections. Standard histopathological and microbiological methods were used. A higher incidence of invasive fungal infections was found in patients with hematologic malignancies as compared to the control group (p < 0.01). The predominant causes of fungal infections were Candida albicans and Aspergillus spp. The incidence of fungal infections caused by Aspergillus was higher (p < 0.05) in patients with hematologic malignancies than in the control group. The independent risk factors for fungal infections were fungal colonization, number of antibiotics and duration of antibiotic therapy, duration of fever and skin rash. A higher proportion of fungal infections was diagnosed on autopsy than during the patients' life (p < 0.01).

Prostaglandin E2 for prophylaxis of oral mucositis following BMT.

Between October 1988 and December 1990, 60 patients with leukaemia (25 with AML, 19 ALL and 16 CML) undergoing BMT were randomised in a double-blind clinical trial to receive prostaglandin E2 (PGE) (Prostin E2, 0.5 mg per tablet) or placebo for prophylaxis of oral mucositis. Patients had to dissolve tablets in the mouth three times daily starting 7 days before BMT and continuing until 21 days after BMT. The incidence of severe oral mucositis was similar for both groups, 55% in patients receiving PGE and 52% in patients receiving placebo. The duration of severe mucositis did not differ between PGE and placebo groups (chi-square 0.95, p = NS). The incidence of HSV infection was significantly higher in patients receiving PGE. Patients with HSV infection receiving PGE also had a higher incidence of severe oral mucositis. The results presented indicate that PGE is not effective for prophylaxis of oral mucositis in BMT recipients.

Total body irradiation with or without lung shielding for allogeneic bone marrow transplantation.

From June 1986 to June 1990, 64 patients with leukaemia (25 acute myelogenous leukaemia, 21 acute lymphoblastic leukaemia and 18 chronic myeloid leukaemia) undergoing marrow transplantation were randomized to receive cyclophosphamide (CY) and fractionated total body irradiation (TBI) without lung shielding (n = 33) or CY and fractionated TBI with lung shielding (n = 31, control group) as conditioning. Patients conditioned with TBI without lung shielding received a significantly higher total lung dose compared with the control group (p less than 0.0001). The 3-year leukaemia-free survival for patients receiving TBI without lung shielding is 54 +/- 18% versus 51 +/- 18% for patients receiving TBI with lung shielding (p = ns). There was no significant difference in the probability of leukaemia relapse (22 +/- 18% for TBI without lung shielding versus 24 +/- 18% for control group; p = ns). The probability of interstitial pneumonitis is 15 +/- 14% for TBI without lung shielding and 5 +/- 5% for TBI with lung shielding (p = ns). A higher incidence of lung fungal infection (15 versus 3%) and interstitial pneumonitis (12 versus 3%) has been documented in patients receiving TBI without lung shielding compared with the control group. The results indicate that higher radiation dose to the lung did not increase antileukaemic efficacy of TBI but seemed to be associated with the increased pulmonary toxicity.

Combination of cyclosporin and methotrexate for prophylaxis of acute graft-versus-host disease after allogeneic bone marrow transplantation for leukemia.

From May 1985 to July 1989, 76 patients with leukemia (30 acute myelogenous leukemia, 24 acute lymphoblastic leukemia and 22 chronic myeloid leukemia) were randomized to receive either cyclosporin (CSP) alone (n = 39) or CSP combined with methotrexate (CSP + MTX, n = 37) for graft-versus-host disease (GVHD) prophylaxis. Patients were conditioned with total body radiation and cyclophosphamide followed by bone marrow infusion from an HLA-identical sibling. Engraftment of the transplanted bone marrow was similar in both groups. The incidence of moderate to severe acute GVHD was significantly higher in the CSP group compared with the CSP + MTX group (20 (51%) versus 9 (25%), chi 2 = 4.76, p less than 0.02). There was no significant difference in the incidence of chronic GVHD. Survival was significantly better for the CSP + MTX group (63 +/- 16%) compared to CSP alone (42 +/- 18%). Leukemia-free survival tended to be better for the CSP + MTX group (55 +/- 17% versus 32 +/- 16%).
