Of 143 consecutive patients who survived at least 6 months after bone marrow transplantation (allogeneic [n = 131]; syngeneic [n = 5]; or autologous [n = 7]) and whose pulmonary function was evaluated before and on at least 2 occasions after BMT, 29 (20%) developed a chronic pulmonary syndrome without evidence for an infectious etiology. Twenty-eight (97%) presented with cough and 22 (76%) with dyspnea; abnormal chest signs were crackles in 23 (79%) and wheeze in 22 (76%). Chest roentgenogram showed pulmonary infiltrates in 15 (52%) cases but was normal in 14 (48%). All patients had major reductions in lung volumes (forced expiratory volume in 1 sec [FEV1]; relaxed vital capacity [VC]; and alveolar volume [VA]), and/or diffusing capacity (pulmonary diffusing capacity [TLCO] and single-breath carbon monoxide coefficient [KCO]). The obstructive component varied with only 18 (62%) patients developing overt airways obstruction (FEV1/VC < 75%), and in 6 of this group the fall in lung volumes preceded the onset of airways obstruction. Open lung biopsy (n = 4) showed both bronchiolitis obliterans and chronic patchy interstitial pneumonitis. The development of this syndrome was associated with acute (P < 0.001) and chronic (P < 0.0001) graft-versus-host disease of other organ systems. Twenty-four (83%) patients had a partial or complete response to immunosuppressive agents. Six (21%) have died, five (17%) of pulmonary complications. We suggest that this syndrome may be a manifestation of chronic GVHD involvement of the lung.

Autologous BMT performed in a 57-year-old woman with relapsed large cell lymphoma was complicated by two consecutive episodes of diffuse alveolar hemorrhage (DAH). The second episode occurred immediately after infusion of autologous BM. DAH is an increasingly recognized complication of autologous BMT and carries a high mortality. It is characterized by dyspnea, cough, bilateral pulmonary infiltrates and progressively bloodier aliquots of bronchoalveolar lavage fluid. The pathogenesis is probably multifactorial involving an initial insult to lung endothelium with inflammatory cells serving as the mediators of subsequent injury. The rapid development of DAH following marrow infusion strongly implicates DMSO as a potential cause in our patient.

In a retrospective analysis, 79 allogeneic bone marrow recipients treated with AmBisome prophylactically or because of proven or suspected invasive fungal infection (IFI) were evaluated in 92 episodes. The median duration of treatment was 14 (range 1-112) days. The mean maximum dose given was 1.64 +/- 0.8 mg kg-1 day-1 and the mean total dose was 1.29 +/- 2.28 g. The overall incidence of reported adverse events was 194, of which none had a serious outcome. In six cases, the drug was withdrawn as a result of toxic or allergic reactions: dyspnoea and flush (3), urticaria (1), cholecystitis (1) and disorientation (one case, probably not related to AmBisome). No anaphylactoid reactions were seen. Laboratory findings, including low serum potassium (48% of the episodes), increased serum creatinine (38%) and increased serum sodium levels (7%), caused no major clinical problems. Thirteen cases of verified IFI were evaluated regarding the efficacy of AmBisome. Survival or cure of the mycotic infection occurred in 5/13 patients (38%). Two patients were treated with AmBisome (3.6 and 3.3 mg kg-1 day-1) because of verified IFI before BMT. One died of IFI. The other died of venoocclusive disease of the liver (VOD) without histological evidence of active IFI. We found a significant (P < 0.05) reduction in autopsy-proven IFI, 12/199 (6%) compared to the period when only conventional doses of amphotericin B were used, 26/227 (11%).

A 34-year-old male suffered from an allergic reaction after inhalation of decontaminating drugs for BMT. Clinical challenge tests were undertaken to determine the causal drug. It was found that vancomycin hydrochloride (VCM) repeatedly induced dyspnea, fever, hypoxia, eosinophilia, and elevation of CRP. Therefore, clindamycin (CLDM) was used instead of VCM for decontamination of patient respiratory tract. Although complete decontamination of the respiratory tract was not achieved during the leukocytopenic period, BMT was successful, and there were no life-threatening infectious complications. Although inhaled VCM-induced allergic reaction may be a very rare complication in the BMT setting, careful clinical attention should be paid to such patients.

A 27-year-old male with acute myelogenous leukemia received an allogeneic bone marrow transplantation (allo-BMT). Pneumocystis carinii pneumonia developed on day 65 after the allo-BMT. The patient was intravenously treated with pentamidine. This resulted in a prompt improvement of his dyspnea and fever, but hyperkalemia occurred during the pentamidine therapy. Treatment with pentamidine was stopped and emergent treatment was started. Nevertheless, the serum potassium level rose to 7.7 mEq/l. Urgent dialysis was performed and the serum potassium level fell to 5.0 mEq/l after treatment. Careful monitoring of the serum potassium level is recommended during intravenous therapy with pentamidine.

Quality of life (QoL) was investigated in 56 BMT recipients. The objective was to compare QoL in terms of physical, emotional, and social functioning between patients within the first year after BMT (n = 15) and patients who were alive more than 1 year after BMT (n=41). The Functional Assessment of Cancer Therapy Scale (FACT-BMT) and the EORTC-Quality of Life Questionnaire (EORTC-QLQ C30) were used to evaluate QoL as perceived by the patients. Results show a significantly reduced general QoL in patients within the first year after BMT. Specific differences were identified on the dimensions of physical and emotional well-being and the symptom scales of appetite loss, fatigue, pain, dyspnea, and nausea and vomiting. QoL improves significantly with time after BMT. We suggest that there should be more integration of QoL expectancy into the pre-BMT information process. Patients should be informed about potential deficits in physical and emotional well-being within the first year after BMT. This could enhance insight and compliance in the critical period early after BMT.

We describe a case of disseminated nocardiosis in a 53-year-old male allogeneic marrow recipient with chronic GVHD, 15 years post BMT. Six months prior to admission he was treated for recurrent chronic GVHD with corticosteroids with a good response. He deteriorated subsequently while still on steroids requiring admission for fever, anorexia, weight loss, productive cough and progressive dyspnoea. On admission he had multiple nodular lesions on chest roentgenogram and subsequently grew Nocardia farcinica in blood culture. N. farcinica is rare post BMT, has a high mortality, is resistant to various antibiotics and needs prolonged antimicrobial therapy. We report the successful management of our patient with single agent trimethoprim-sulphamethoxazole.

We describe a patient who developed Aspergillus tracheobronchitis after BMT. She complained of progressive dyspnea on day +165 and her respiratory function deteriorated rapidly. Although neither early chest X-rays nor CT scans were negative, bronchoscopy revealed formation of a pseudomembrane around the bronchial walls. Based upon pathological and microbiological examinations, she was diagnosed as having invasive Aspergillus tracheobronchitis. Retrospectively analyzed, the Aspergillus circulating antigen detection tests became positive before clinical symptoms developed, and may be beneficial for early diagnosis of Aspergillus tracheobronchitis. This form of aspergillosis should be regarded as one of the serious complications after BMT.

We describe two cases of severe constrictive pericarditis arising after allogeneic BMT conditioning involving total body irradiation and melphalan to treat Philadelphia-chromosome positive ALL. Both patients required pericardectomy, resulting in marked improvement in ventricular filling. However, a degree of right-sided cardiac failure persisted in both patients secondary to restrictive cardiomyopathy. Constrictive pericarditis has not been previously described after BMT, but has been observed following thoracic radiotherapy for malignancy, usually involving a substantially higher radiation dose. Pericardial constriction and restrictive cardiomyopathy should be considered as causes of breathlessness and/or oedema occurring late after BMT. Bone Marrow Transplantation (2000) 25, 571-573.

A total of 75 patients underwent sibling allogeneic stem cell transplantation (SCT) for chronic myeloid leukaemia in first chronic phase from 1984 to 2000. Of these patients, 51 (68%) were alive at a median follow-up of 98 months (range 34-217 months). Nine (18%) patients relapsed and seven (14%) received donor lymphocyte transfusions. Quality of life (QoL) was assessed cross-sectionally using the EORTC QLQ-C30, a Leukaemia-BMT-specific module and questionnaires on sexual functioning, fertility and late effects. A total of 46 (90%) replied. Scores for Role (P=0.018) and Cognitive (P<0.001) function were significantly lower when compared to an age-adjusted general population. Dyspnoea (P=0.022) and Financial Difficulties (P<0.001) were significantly more common in the SCT group. No difference was found for scores in the Physical, Emotional and Social domains or the overall Global Health Status/QoL. Decreased sexual functioning was found in one-third of respondents. Although most BMT recipients reported a good QoL, a minority have difficulty with reintegration into professional roles and consequent monetary problems. Identified cognitive and sexual impairments highlight the need for long-term access to psychosocial support.
