The impact of follicular lymphoma on health-related quality of life.

BACKGROUND: The purpose of this study was to determine whether there was a relationship between disease activity and health functioning, as measured by a range of patient-reported outcome (PRO) measures in patients with follicular lymphoma (FL). PATIENTS AND METHODS: A total of 222 patients with FL were recruited from eight sites across the UK and they completed a number of PRO measures. The participants were analyzed across five disease states: 'active disease-newly diagnosed', 'active disease-relapsed', 'partial response', 'complete response' and 'disease free'. The relationship between these disease states and their level of health functioning was assessed as well as the relationship between being 'on' or 'off' chemotherapy and disease state. RESULTS: In terms of health-related quality of life (HRQoL), participants in the relapsed category had the lowest mean physical well-being, emotional well-being, functional well-being and social well-being score. In a regression analysis, the 'active disease-relapsed' group acted as a significant predictor for each PRO variable. In addition, the remission group acted as a significant predictor of high anxiety scores as measured by the Hospital Anxiety and Depression Scale. CONCLUSION: The results of this study demonstrate that various aspects of patient-reported health outcomes differ according to disease state in patients with FL. For those patients who have relapsed, they are more likely to experience worse HRQoL and other patient-reported health outcomes than patients newly diagnosed, in partial or complete remission or when completely disease free.

Fludarabine phosphate and melphalan: a reduced intensity conditioning regimen suitable for allogeneic transplantation that maintains the graft versus malignancy effect.

Reduced intensity conditioning (RIC) for allogeneic stem cell transplantation allows stable donor cell engraftment with the maintenance of a graft versus malignancy effect. Many different regimens exist employing various combinations of chemotherapy, radiotherapy and T-cell depletion. We examined the role of non-T-cell depleted RIC regimens in 56 patients with haematological malignancies. Patients received fludarabine phosphate for 5 days (30 mg/m2 in 35 patients, 25 mg/m2 in 21 patients) and melphalan for 1 day (140 mg/m2 in 36 patients, 100 mg/m2 in 20 patients). Immunosuppression was with CyA alone in 33 patients and CyA/MTX in 23 patients. Twenty-four of the 26 patients with chimerism data showed >95% donor chimerism at 3 months post transplant. aGVHD occurred in 18% of patients receiving CyA/MTX compared to 53% of patients receiving CyA. The 100-day mortality rate was 0.16 (95%CI 0.08-0.28) and 1-year nonrelapse mortality was 0.24 (95%CI 0.13-0.38). Thirty-three patients remained alive and in CR at a median of 19 months post transplant (range 3-38 months). We have shown that patients transplanted with fludarabine phosphate, melphalan 100 mg/m2 and with CyA/MTX as post transplant immunosuppression can achieve good disease control with an acceptable level of toxicity. Further studies are required to confirm these findings.

CAMPATH-1H monoclonal antibody in therapy for previously treated low-grade non-Hodgkin's lymphomas: a phase II multicenter study. European Study Group of CAMPATH-1H Treatment in Low-Grade Non-Hodgkin's Lymphoma.

PURPOSE: CAMPATH-1H is a human immunoglobulin G1 (IgG1) anti-CD52 monoclonal antibody (MAb) that binds to nearly all B-cell and T-cell lymphomas. We report here the results of a multicenter phase II trial of CAMPATH-1H in patients with advanced, low-grade non-Hodgkin's lymphoma (NHL) who were previously treated with chemotherapy. PATIENTS AND METHODS: Fifty patients who had relapsed (n=25) after or were resistant (n = 25) to chemotherapy were treated with CAMPATH-1H 30 mg administered as a 2-hour intravenous (i.v.) infusion three times weekly for a maximum period of 12 weeks. RESULTS: Six patients (14%) with B-cell lymphomas achieved a partial remission (PR). Patients with mycosis fungoides appeared to respond more frequently (50%; four of eight patients, which included two complete remissions [CRs]). Lymphoma cells were rapidly eliminated from blood in 16 of 17 patients (94%). CR in the bone marrow was obtained in 32% of the patients. Lymphoma skin lesions disappeared completely in four of 10 patients and partial regression was obtained in three patients. Lymphadenopathy and splenomegaly were normalized in only 5% and 15% of patients, respectively. Lymphopenia (< 0.5 x 10(9)/L) occurred in all patients. World Health Organization (WHO) grade IV neutropenia occurred in 14 patients (28%). Opportunistic infections were diagnosed in seven patients and nine patients had bacterial septicemia. Death related to infectious complications occurred in three patients. CONCLUSION: CAMPATH-1H had a significant but limited activity in patients with advanced, heavily pretreated NHL. The most pronounced effects were noted in the blood and bone marrow and in patients with mycosis fungoides. The risk for serious infectious complications needs to be considered for severely ill patients who are evaluated for CAMPATH-1H treatment.

Unrelated donor marrow transplantation between 1977 and 1987 at four centers in the United Kingdom.

Retrospectively we analyzed the histocompatibility data and clinical results of bone marrow transplantation in 51 patients who received marrow from unrelated donors (UD) from 1977 to 1987 at one of four UK BMT centers. We compared the results with those obtained in 51 transplants carried out at the same centers using HLA-identical (ID) sibling donors. Of the UD/recipient pairs 32 (63%) were serologically identical for HLA A, B, and DR antigens, and 37% showed varying degrees of mismatch. UD-BMT primary diagnoses were: severe aplastic anemia or Fanconi's anemia (n = 17), acute leukemia (n = 11), chronic myeloid leukemia (n = 21), and other conditions (n = 2). T cell depletion of the graft was associated with a significant improvement in survival in both UD and ID-BMT. Graft failure was more common in recipients of UD than of ID transplants (13 [25%] vs. 5 [10%] P = 0.05) but there was no significant difference in the frequency of acute or chronic graft-versus-host disease. Actuarial survival was superior for recipients of ID transplants (UD vs. ID: 49% vs. 78%, respectively, at 3 months; 32% vs. 63% at one year). Reduced survival for recipients of UD-BMT was confirmed in case control regression analysis (relative risk 3.0, P = 0.01). Nevertheless in patients whose only alternative is a partially mismatched family donor we think that UD-BMT is justified.

Magnetic affinity colloid (MAC) cell separation of leukemia cells from autologous bone marrow aspirates.

A colloidal suspension of Co2B with avidin irreversibly adsorbed to the surface has been used with biotinylated antibodies and lectins to eliminate specific cell populations from mixtures with peripheral blood or bone marrows. Using the monoclonal antibodies CF-1 and PM-81 with this magnetic affinity colloid (MAC), we can eliminate five logs of K562 cells from mixtures with peripheral blood or marrow cells as determined by a linear limiting dilution clonogenic assay. We have also used this separation to eliminate clonogenic leukemia cells from fresh samples of peripheral blood and bone marrow from relapsed acute leukemia patients. Using CF-1 alone or in combination with PM-81, we eliminated two logs of colonies and clusters of leukemia cells from the fresh samples. The same antibodies used with MAC separation of hematologically normal marrows allow recovery of greater than 30% of the hematopoietic progenitors.

A phase II protection study of BB-10010 in patients with high grade non-Hodgkin's lymphoma undergoing intensive chemotherapy.

The aim of this study was to determine whether administration of BB-10010, a synthetic stem cell inhibitor, would allow more intensive chemotherapy to be administered to patients with newly diagnosed high grade NHL. Thirteen patients were randomised to receive BB-10010 concurrently with dose-intensified BEMOP/CA chemotherapy (7 patients) or chemotherapy alone (6 patients). Although the mean neutrophil count of BB-10010 treated patients was higher following cycles 1, 2 and 3 of chemotherapy compared with those receiving chemotherapy alone, there was no difference in the mean number of cycles tolerated, blood component usage and hospital admissions due to infections. No specific toxicity of BB-10010 was identified. Whilst BB-10010 can be administered safely, it does not improve the ability of patients to tolerate intensive chemotherapy for high grade NHL.

T cell depletion in bone marrow transplantation.

Prior to the introduction of T cell depletion graft-versus-host disease (GVHD) was the major cause of transplant-related mortality. Why has the remarkable technical achievement of efficient T cell depletion, which has virtually eliminated severe GVHD over the last few years, failed to reduce mortality and increase disease-free survival? This review examines the value of T cell depletion based on recent clinical experience. It surveys the directions that are being pursued in an effort to solve the problems that have arisen and indicates how this is leading to a greater understanding of the mechanisms involved in GVHD and the graft-versus-leukaemia effect.

The gut mucosal barrier in bone marrow transplantation.

The damage to the small bowel mucosal barrier was studied prospectively in 26 patients undergoing bone marrow transplantation. The conditioning regimens resulted in the small bowel mucosa becoming more permeable for up to 4 weeks. Acute graft-versus-host disease also compromised barrier function. There was no difference in gut damage between conditioning with chemotherapy only and chemoradiotherapy, but damage was greater in patients 30 years of age and above.

Use of IgM enriched intravenous immunoglobulin (Pentaglobin) in bone marrow transplantation.

In a study of 63 allogeneic and autologous bone marrow transplants, patients were randomized to receive the IgM and IgA enriched intravenous immunoglobulin (IVIG) preparation (Pentaglobin). Pentaglobin has been postulated to have anti-endotoxin properties and one of the aims of the study was to measure endotoxin levels in these patients together with the clinical sequelae of infection. The anti-endotoxin effects of Pentaglobin were found to reside in the IgM fraction. Those patients who received Pentaglobin were significantly protected from dying from infection in the first 100 days after the transplant, although it was not actually possible to document bacterial infections as the cause of death in the control patients. Peak endotoxin levels were significantly reduced (p = 0.02) in those patients receiving Pentaglobin. Liver damage as assessed by liver enzyme abnormalities correlated significantly with the presence of endotoxaemia greater than 25 pg/ml and up to 70% of pyrexial episodes were associated with endotoxaemia. Our results suggest that Pentaglobin is useful in reducing hepatic toxicity and this may be related to a reduction in endotoxaemia.

Bone marrow transplantation for adults and children with poor risk acute lymphoblastic leukaemia in first complete remission.

Thirty-two patients with poor risk acute lymphoblastic leukaemia in first complete remission received bone marrow transplants (BMT) from fully matched family donors. Their ages ranged from 7 to 41 (median 23) years. Nine patients were aged 16 years or less. Patients were selected for BMT because they had risk factors for relapse with standard treatment approaches. In particular the children who were selected for BMT had presenting blast counts of greater than or equal to 90 x 10(9)/l or null immunophenotypes. The overall disease-free survival was 50% with a relapse risk of 31% at 9 years. Patients aged less than 16 years had a much lower risk of both graft-related disease and relapse than did older patients (disease-free survival 89% for those aged 7-16, 48% for those aged 17-26, 24% for those aged 26-41). We conclude that selection of BMT for young patients with poor risk features is entirely justified but that the prognosis for older patients is poor even after BMT.

Safe application of a 13-Gy split dose total body irradiation schedule prior to bone marrow transplantation.

Two conditioning regimens for bone marrow transplantation for patients with acute lymphoblastic leukaemia were compared. Both regimens (VVRAPID and VVRAPID-X) incorporated the same cytotoxic chemotherapy but differed in the radiation dose; VVRAPID employed a single fraction of 10.5 Gy and VVRAPID-X employed 10.5 Gy followed 4 days later by a further dose of 2.5 Gy. The 13-Gy split-fraction schedule was well tolerated with no significant increase in infection or requirement for blood products. An increase in gastrointestinal toxicity occurred but responded to increased oral anti-diarrhoeal agents. Overall survival and relapse rates did not differ significantly between the two groups. There was a trend for the 13-Gy schedule to reduce the graft failure rate following T cell-depleted bone marrow transplants.

Glutamine and vitamin E in the treatment of hepatic veno-occlusive disease following high-dose chemotherapy.

Hepatic veno-occlusive disease (VOD) of the liver is a common complication following high-dose cytotoxic therapy for bone marrow transplantation (BMT). Liver injury is believed to occur following free radical damage to endothelial cells of the sinusoids and small hepatic veins. Glutathione the main antioxidant of the cytosol becomes depleted following chemotherapy. Animal studies have shown that glutamine infusions can maintain glutathione levels and protect against free radical injury. We present two cases of established VOD successfully treated with intravenous glutamine (as dipeptide) and oral vitamin E. Although both cases have possible confounding factors we believe that these give support to the notion that glutamine/vitamin E may have a role in the prophylaxis and treatment of VOD. Further formal trials are indicated.

Parenteral glutamine protects hepatic function during bone marrow transplantation.

Hepatic veno-occlusive disease (VOD) of the liver is a common complication following high-dose cytotoxic therapy for bone marrow transplantation (BMT). The major pathological changes are seen in centrilobular (zone 3) hepatocytes and adjacent endothelium. Glutathione (GSH) becomes depleted following chemotherapy and experimental evidence suggests reduced levels predispose to centrilobular hepatocyte and endothelial cell injury. Animal studies have shown that glutamine infusions can maintain GSH levels and protect against free radical injury. We have prospectively studied the effect of glutamine supplementation during BMT. Thirty-four patients undergoing BMT were randomised to receive either glycl-L-glutamine (n = 18) or an isonitrogenous mixture of non-essential amino acids (n = 16). Glutamine was shown to significantly preserve protein C (days +4 and +7, P < 0.05) and albumin levels (days 0 and +4, P < 0.02). Markers of thrombin and plasmin generation (thrombin-antithrombin, prothrombin fragment F1+2 and plasmin-antiplasmin levels) were not significantly changed between the two groups. These findings suggest that glutamine preserves hepatic function but does not alter thrombin or plasmin generation during BMT. Previous studies have shown reductions in protein C, albumin, factor X and factor VII levels post BMT. Falling protein C levels have been shown to be predictive of severe VOD. These data suggest a role for glutamine in the protection of hepatic function following BMT.

A placebo controlled trial of diazepam and oxprenolol for anxiety.

Sixty-two patients with moderately severe anxiety symptoms were treated in a double bline 3-week trial with either oxprenolol, diazepam or placebo. The Hamilton Anxiety Scale and a Target symptom improvement score were the main measures of change used. All treatment groups significantly improved in the three weeks of the trial. However in the third week of treatment improvement was greater in the diazepam and oxprenolol groups. Observer preferences significantly favoured the diazepam group. The implications of the study were discussed.

Polymerase chain reaction aids in the diagnosis of an unusual case of Aspergillus niger endocarditis in a patient with acute myeloid leukaemia.

Endocarditis secondary to Aspergillus niger has not been described in a leukaemic patient. We describe a case of A. niger endocarditis in a patient with acute myeloid leukaemia and refractory fever. The microbiological cause of his endocarditis was initially misdiagnosed because he fulfilled the Duke criteria for enterococcal endocarditis. A polymerase chain reaction test utilizing pan-fungal primers detected a product from an Aspergillus sp. The DNA was subsequently sequenced and was found to have 100% homology with A. niger. A postmortem revealed fungal endocarditis secondary to disseminated aspergillosis, without evidence of bacterial endocarditis. The patient was found to have a lung aspergilloma that was possibly occupationally acquired, and may have been long standing.

Intermittent superior vena cava syndrome caused by a Hickman catheter.

A case of intermittent superior vena cava syndrome caused by a Hickman catheter is reported. The symptoms resolved on removal of the catheter. The use of anticoagulants in conjunction with indwelling venous catheters is discussed.

Group counselling for relatives of hospitalized presenile dementia patients: a controlled study.

A controlled study is reported in which the effects of time-limited group counselling for the relatives of hospitalized presenile dementia patients is evaluated. The results indicate that such group counselling was effective in increasing relatives' morale, increasing their knowledge about dementia, and increasing the number of activities performed with the patient during visits, but had no effect upon the frequency or duration of visits or the amount of verbal and non-verbal communication between patient and relative. All changes achieved were maintained at three month follow-up.
