Myeloablative chemo (+/- radio) therapy and rescue with ABMT has been used as final consolidation therapy in 18 patients with AML in first remission. In seven (6 autologous, 1 syngeneic) marrow reinfusion was followed by iv IL-2. One patient, who commenced IL-2 4 days after BMT, died from pulmonary oedema due to the capillary leak syndrome. Thereafter, treatment with IL-2 was delayed until the platelet count reached 30 x 10(9)/l. All patients developed reversible hypotension (treated with infusion of colloid), but treatment was otherwise well tolerated. With 21-58 months (median 32 months) from the time of ABMT there has been one relapse (actuarial risk 17%, 95% confidence intervals (CI) 3-31%). The disease-free survival is 71% (95% CI 38-100%). Eleven patients with comparable remission induction and consolidation therapy, and an identical interval between diagnosis and ABMT (5-11 months, median 6 months) received an autograft without immunotherapy. With 24-45 months (median 29 months) follow-up the actuarial disease-free survival is 36% (95% CI 8-64%), the actuarial relapse risk is 54% (95% CI 18-90%). We conclude that immunotherapy given after ABMT to patients with AML in first remission when the platelet count exceeds 30 x 10(9)/l is safe and may induce an immunological environment which results in the elimination of residual leukaemia.

Practical approaches to the initial evaluation of solid organ transplant patients, BMT patients, and HIV-infected patients with pulmonary disease are summarized in Figures 2, 3, and 4. These algorithms are meant to be used as guidelines for the clinician. The clinical setting will ultimately determine the extent and speed of the evaluation. Patients who are recipients of solid organ transplants and have pulmonary symptoms may have focal or diffuse changes or may have normal chest radiographs. In all these groups, sputum is obtained by expectation. If a pathogen is found in any of the groups, it is treated. When no pathogen is found on sputum examination in patients with focal disease, empiric antibiotic therapy is given. If the patients do not improve on the empiric antibiotics, then bronchoscopy is performed. Some centers proceed directly to bronchoscopy before antibiotics are started in the hope of directing antibiotic therapy. Patients who have a normal CXR or diffuse infiltrates and no identified pathogen on examination of sputum undergo bronchoscopy, and the protocol is followed until a diagnosis is made (see Fig. 2). Patients who have received a BMT and who present with pulmonary symptoms are treated as shown in Figure 3. The CXR will reveal if the infiltrate is focal or diffuse. Those with focal infiltrates are treated with broad-spectrum antibiotics for 48 to 72 hours. If the symptoms and signs do not show some resolution, then bronchoscopy is usually performed. The effect of diffuse infiltrates in BMT patients depends to a large extent how far along in recovery from the transplant the patient is when they develop the infiltrates. During the first 30 days posttransplant, pulmonary edema commonly occurs, and the infiltrates may resolve with diuresis. If the patient is not clinically fluid overloaded or they do not respond to the diuretic therapy, then bronchoscopy with BAL is indicated. Finally, many HIV-infected patients may present with pulmonary symptoms. They may have a normal CXR or a diffuse or focal pattern (Fig. 4). All patients are subjected to sputum induction to identify a pathogen. If one is identified, it is treated. Should the patient not respond to treatment adequately or a pulmonary pathogen is not found, then bronchoscopy with BAL, protected specimen brush, or a transbronchial biopsy is attempted. The above schema is a general guideline to the initial evaluation of pulmonary disorders in the ICP. The respiratory abnormality is found in most of the cases if these algorithms are closely followed. If the patient does not improve or deteriorates further, additional diagnostic procedures such as video-assisted thorascopic lung biopsy or CT-directed transthoracic needle biopsy may be needed.

Lymphoproliferative disorders (LPD) occur often in EBV-infected patients, especially in solid-organ and haematopoietic stem cell transplant recipients. The risk of developing LPD ranges from 1 to 25% and depends on the type of transplantation. We are presenting the case of a 9-year-old boy with acute myelogenous leukaemia in second remission, who developed LPD after matched unrelated donor bone marrow transplantation (MUD BMT) not identical in two loci. On day 50 after BMT the patient presented with fever and symptoms of paronychia. Two weeks later, bilateral cervical tenderness and adenopathy and hepatosplenomegaly developed. Bone marrow biopsy confirmed continuing remission. An extensive infection workup, including bacterial, mycotic and CMV infection yielded negative results. Basing on clinical picture and suspecting LPD, EBV-PCR was performed. The patient was found to have extremely high EBV DNA levels (4.905.152 genomes/mcg) in the peripheral blood. On days 64 and 73 after BMT, the patient received two doses of rituximab (MabThera) (375 mg/m(2)) After the first dose of rituximab EBV DNA copy numbers decreased to 707.723/mcg. However the patient's general condition was worsening; 71 days after BMT increasing aplasia and symptoms of venoocclusive disease (VOD) developed. The patient received two doses of defibrotide (Novarid). Despite of intensive therapy, progressive hepatic failure and increasing pulmonary oedema led to the patient's death, on day 96 after BMT.
