Abstract
BACKGROUND Myelosuppression is the main hematotoxic effect of 6-mercaptopurine (6-MP), which is an antimetabolite chemotherapy drug. Immune hemolytic anemia associated with this drug has not been previously reported. CASE REPORT A 67-year-old man with chronic myelomonocytic leukemia presented with anemia 2 weeks after 6-MP therapy had been initiated. Additional tests provided laboratory evidence of hemolysis. When treatment was stopped, the patient's condition and laboratory results showed a progressive improvement. RESULTS The direct antiglobulin test was positive for IgG. The eluate and the serum were not reactive with panel red cells but reacted with 6-MP-treated red cells, while the normal serum pool was unreactive. The direct antiglobulin test was no longer positive by 20 days after the cessation of 6-MP therapy. CONCLUSION This drug, 6-MP, should be added to the list of drugs that have been reported to cause immune hemolytic anemia by means of the so-called hapten mechanism.

Abstract
The Spanish PETHEMA group designed a protocol for newly diagnosed PML/RARalpha-positive acute promyelocytic leukemia (APL) in which induction and consolidation followed the original AIDA regimen, except for the omission of cytarabine and etoposide from consolidation. Induction consisted of 45 mg/m(2) all-trans retinoic acid (ATRA) daily until complete remission (CR) and 12 mg/m(2) idarubicin on days 2, 4, 6, and 8. Patients in CR received 3 monthly chemotherapy courses: idarubicin 5 mg/m(2)/d x 4 (course no. 1), mitoxantrone 10 mg/m(2)/d x 5 (course no. 2), and idarubicin 12 mg/m(2)/d x 1 (course no. 3). Maintenance therapy consisted of 90 mg/m(2)/d mercaptopurine orally, 15 mg/m(2)/wk methotrexate intramuscularly, and, intermittently, 45 mg/m(2)/d ATRA for 15 days every 3 months. Between November 1996 and December 1998, 123 patients with newly diagnosed PML/RARalpha-positive APL from 39 centers were enrolled. A total of 109 patients achieved CR (89%; 95% confidence interval [CI], 83 to 95), 12 died of early complications, and the remaining 2 were resistant. Consolidation treatment was associated with very low toxicity and no deaths in remission were recorded. Molecular assessment of response by reverse transcriptase-polymerase chain reaction (RT-PCR) showed conversion to PCR-negative in 48 of 99 (51%) and 82 of 88 patients (93%) after induction and consolidation, respectively. The 2-year Kaplan-Meier estimates of overall survival and event-free survival were 82% +/- 4% and 79% +/- 4%, respectively. For patients who achieved CR, the 2-year disease-free survival (DFS) was 92% +/- 3%. These data indicate that a significant reduction in toxicity might be obtained in APL using a less intensive consolidation without apparently compromising the antileukemic effect. These results also suggest a minor role for cytarabine and etoposide in the treatment of newly diagnosed PML/RARalpha-positive APL patients.

Abstract
BACKGROUND AND OBJECTIVE The aim of the present work was to analyze the immunophenotypic changes in neutrophil granulocytes (NG) and their evolution over time in 16 healthy donors who received G-CSF for stem cell mobilization for allogeneic peripheral blood stem cells (PBSC) transplantation. DESIGN AND METHODS The mobilization schedule consisted of G-CSF (Filgrastimq, Amgen) 10 microg/kg, s.c. for five consecutive days. Apheresis began 16-24h after the last dose of G-CSF. Immunophenotypic analysis (CD10, CD14, CD15, CD16, CD71, CD34 and HLA-DR) of NG and measurement of G-CSF serum levels were performed before G-CSF administration (day 0), on the fifth day of G-CSF treatment and days +7 and +30 after the last dose of G-CSF. RESULTS After G-CSF administration, peripheral blood NG presented increased expression of HLA-DR, CD34, CD14, and CD71, in addition to decreased expression of CD10 and CD15 and CD16 fluorescence mean intensity. The phenotypic changes on NG were parallel to serum G-CSF levels. All the phenotypic changes returned to the baseline values by one month after the end of G-CSF treatment. No changes were found in the expression of HLA-DR on T and B-lymphocytes. INTERPRETATION AND CONCLUSIONS These immunophenotypic changes suggest that after G-CSF administration NG from healthy donors who received G-CSF for stem cell mobilization carry transient features of immature phenotype and have increased functional activity.

Abstract
Results of 378 consecutive elderly patients (> or = 65 years) undergoing coronary stenting were compared with those of 601 younger patients. Although the restenosis rate was similar in the 2 groups, age > or = 65 years was an independent predictor of in-hospital mortality (relative risk 5.4, 95% confidence interval 1.2 to 20.1) and follow-up mortality (relative risk 2.8, 95% confidence interval 1.3 to 6.1).

Abstract
BACKGROUND To analyze the usefulness of bone marrow (BM) study in the diagnosis of fever of unknown origin (FUO) in patients infected by the human immunodeficiency virus (HIV) in a single center during a period of 42 months. PATIENTS AND METHODS 182 episodes of FUO in 162 patients p3th HIV infection were studied. Age, sex, risk factor for HIV infection, hemoglobin level, counts of leucocytes, neutrophils, lymphocytes, CD4 positive lymphocytes, platelets and levels of hepatic enzymes, albumin and beta 2-microglobulin were studied. BM aspirate was performed in all episodes for cytologic and microbiologic examination, and BM biopsy was done in 43. Analysis of factors related with the probability of diagnosis by BM examination was carried out. RESULTS The median age was 33 years (range, 22-70), and 123 were males. Drug abuse was the most frequent risk factor for HIV infection (63%). One hundred thirty patients had previous AIDS diagnosis before they were evaluated for unexplained fever. A specific diagnosis was achieved in 161 episodes (88%) and the most frequent diagnoses were Mycobacterium spp. (55%) and Leishmania spp. (14%) infections. Fifty-four episodes (30%) were diagnosed by BM examination, and in 36 (20%) BM study was the only diagnostic tool. Examination of the BM aspirate yielded the diagnosis in 40 out of the 178 episodes (13%), whereas BM biopsy was a diagnostic tool in 8 (19%); in 9 additional cases (21%) granulomas were observed. Microbiologic study of BM smears for mycobacterial infections was positive in 28 of the 143 episodes (19%), and the culture for Leishmania was positive in 2 out of the 42 cases. The presence of thrombocytopenia (< 75 x 10(9)/l) and elevated serum levels of aspartate-aminotransferase (AST) (> 100 U/l) were the factors associated with a high probability to obtain the diagnosis through BM study. CONCLUSIONS In patients infected by the HIV and unexplained fever, BM examination is an useful procedure for the diagnosis, particularly in areas where infections by Mycobacterium spp. and Leishmania are prevalent. So that, in our setting, systematic use of this procedure is justified for diagnosis of FUO in those patients.

Abstract
BACKGROUND Abnormalities of the long arm of chromosome 3 (3q) involving bands 3q21 and/or 3q26 occur in 2-6% of myeloid malignancies. Trilineage myelodysplasia, especially in the megakaryocytic line, is a characteristic feature. Additional abnormalities of chromosomes 5 and 7 are usually present. The response to treatment and prognosis are poor. PATIENTS AND METHODS The main clinical, cytologic (bone marrow aspirate and biopsy) and cytogenetic characteristics as well as the response to the treatment in 10 patients with 3q abnormalities diagnosed in a single hospital in a period of 8 years are referred. RESULTS Eight patients had acute non-lymphoblastic leukemia, being de novo in five of them. The median value of hemoglobin was 87 g/l (range: 51-148), white blood cells count 5.8 x 10(9)/l (1.2-47.1) and platelet count 34 x 10(9)/l (5-182). The morphological findings in the study of the bone marrow were: dyserythropoietic features (7 patients), dysgranulopoietic abnormalities (5 patients) and small-sized megakaryocytes with hypolobulated nuclei (8 patients). Fibrosis was observed in the 4 cases in which a bone marrow biopsy was performed. In addition to the 3q alteration, abnormalities of chromosomes 7 (4 patients), 5q (2 patients) and +8 (2 patients) were present. Four patients received intensive chemotherapy and in two of them a complete remission was achieved, but relapse occurred at 3 and 5 months, respectively. All patients have died, the median survival being 7 months. CONCLUSIONS 3q abnormalities define a subtype of myeloid malignancies with characteristic clinical and morphological features. The response to therapy and survival are poor.

Abstract
Immunosenescence is characterized by an increase in autoantibody production. Because both T and B cell stimulation are key events for producing antibodies, we investigated early T and B cell activation by means of CD23 and CD40L (two very early activation antigens). PBMC from elderly humans (EH) were studied following culture with either medium, anti-CD3mAb, rIL-4, or PMA + ionomycin. CD23 expression on elderly B cells after anti-CD3 challenge of PBMC, a reflect of T-dependent B cell activation, was clearly defective. Conversely, CD23 expression on EH B cells following activation with soluble factors as rIL-4 was preserved. CD40L expression was also impaired in EH T cells following anti-CD3 challenge. However, activation by means of PMA and/or ionomycin was preserved both in T cells (CD40L expression) and in B cells (CD23 expression). These results indicate that a defective T-dependent B cell activation related to defective T cell activation located between surface membrane and PKC/ionomycin function is an intrinsic characteristic of immunosenescence. We have not found intrinsic B-cell defects, and we conclude that the characteristically impaired early B cell activation in EH is mostly due to T cell defects.

Abstract
BACKGROUND To analyze the etiology, treatment response and prognostic factors in 88 episodes of pneumonia in patients with hematological malignancies diagnosed in one center during a period of 30 months. PATIENTS AND METHODS 88 episodes of pneumonia in 69 adult patients were studied. Age, sex, hematological malignancy and its treatment, existence of neutropenia and hypogammaglobulinemia, administration of immunosuppressive agents, type (hospital or community-acquired) and localization of pneumonia, presence of respiratory failure and treatment response were reported. For etiologic diagnosis of pneumonias, cultures of blood, sputum, pleural fluid and bronchoalveolar lavage (BAL), as well as Legionella pneumophila, Aspergillus fumigatus and Streptococcus pneumoniae antigen detection in urine were performed. Univariate and multivariate analyses of prognostic factors for pneumonia evolution were carried out. RESULTS The median age was 63 years. Acute leukemias (AL) were the predominant hematological malignancies. Microbiologic documentation was obtained in 40 (45%) of pneumonias. Fiberoptic bronchoscopy with BAL (71%) was the diagnostic procedure with highest yield followed by blood cultures (25%). Streptococcus pneumoniae (13) was the most frequent isolated pathogen, followed by Legionella pneumophila (6) and Pseudomonas aeruginosa (6). A significantly higher prevalence of Streptococcus pneumoniae was observed in community-acquired pneumonia. The overall mortality rate was 20%. Respiratory failure (p = 0.0009), existence of neutropenia (p = 0.0023), age equal or higher than 60 years (p = 0.012) and prolonged administration of immunosuppressive agents (p = 0.015) were the prognostic factors associated with unfavourable evolution of pneumonias in the multivariate analysis. CONCLUSIONS The etiologic diagnosis of pneumonia in patients with hematological malignancies was only achieved in a half of cases. In our series, the high prevalence of Legionella pneumophila can be attributed to the special epidemiologic characteristics of our hospital. Prognostic factors of pneumonia are related to individual factors as well as to the hematological status of patients.

Abstract
INTRODUCTION the antigen CD28, expressed in most T cells, has co-stimulatory properties and plays a pivotal role in clonal T cell anergy mechanisms. METHODS we have compared proliferative T cell responses after anti-CD3 or in phorbol myristate acetate activation with concomitant CD28 signal in peripheral blood mononuclear cells from healthy donors aged over 65 [elderly donors; ED] and young healthy donors (YD); mean age 30+/-2.7 years). RESULTS no proliferative responses were observed in ED and YD with anti-CD28 monoclonal antibody alone. These responses both were defective in ED, particularly after anti-CD3 monoclonal antibody stimulus (7604 compared with 12,438 c.p.m. in YD, P=0.001) and were corrected when anti-CD28 monoclonal antibody was added to the culture (17,216 vs 18,536, not significant). Functional integrity of the CD28 co-stimulatory pathway was demonstrated by analysis of CD25 expression, interleukin-2 secretion and interleukin-2 gene expression on T cells from ED and YD. Age-associated phenotypic T cell changes were not crucial for an adequate CD28 response. CONCLUSION these experiments demonstrate the integrity of the CD28 pathway in elderly people, and suggest that ageing does not affect different T cell activation pathways equally.

Abstract
BACKGROUND To analyze the main clinical and biological data and the response to therapy in 15 patients with primary gastrointestinal lymphoma (PGIL) from a series of 76 patients with HIV related non-Hodgkin's lymphoma (NHL) diagnosed in a single institution in a 13 years period. PATIENTS AND METHODS The main clinical, biological and evolutive data were recorded. Pathologic diagnosis of PGIL was made according to the REAL classification. Clinical stage was determined by the Ann Arbor system modified by Rohatiner et al. Response to therapy as well as overall survival (OS) were studied. Results were compared with non-PGIL HIV-related NHL patients. RESULTS Mean age of the series was 38 years. Thirteen patients were male, and 8 intravenous drug abusers. Then had bad performance status (ECOG 2-4) and 11 B symptoms. All patients had a high grade malignant PGIL and the localization was gastric in 10 cases. The most frequent symptoms were abdominal pain (11 cases), gastrointestinal bleeding (4) and dysphagia (3). Ten patients had advanced stages (IIE2-IV). The median CD4 cell count was lower in PGIL patients (92 x 10(6)/l vs 148 x 10(6)/l; p < 0.05). Thirteen patients received intensive chemotherapy with CHOP regimen (in 5 surgical procedures were previously made). Complete response (CR) was obtained in 4 patients (31%) and 1 of them relapsed. Median OS was 10 months vs 16 months non-PGIL HIV-related lymphoma patients (p < 0.05). CONCLUSIONS PGIL in HIV patients often presented advanced stages and high grade of malignancy. The most common localization is the stomach, and these patients usually have bad performance status and a low CD4 lymphocyte count. Response to therapy is poor. In our series OS was worse in PGIL patients than in the rest of HIV-related NHL, possibly due to the high degree of immunosuppression in the formers.

Abstract
BACKGROUND AND OBJECTIVE The threshold for prophylactic platelet transfusions has been classically established at 20,000/microL. In 48 patients with de novo acute myeloblastic leukemia (AML) we analyzed the effect of reducing the threshold for prophylactic platelet transfusion from 20,000/microL (group A) to 10,000/microL (group B) after induction and consolidation chemotherapy. DESIGN AND METHODS Forty-eight adult patients with de novo AML diagnosed in a single institution in a nine year period were enrolled in the study. Between January 1989 and December 1993 the patients received prophylactic platelet transfusions when their platelet count was below 20,000/microL (group A), and from January 1994 to March 1998 prophylactic platelet transfusions were indicated below 10,000/microL or between 10,000/microL and 20,000/microL if there was any consumption factor. RESULTS The mean number (SD) of platelet transfusions during induction was 8.4 (5.3) in group A and 8.5 (5.5) in group B; and during consolidation 4.7 (3.4) in group A and 4.6 (3.8) in group B (p = n.s.). Excluding the cases with consumption factors from the analysis, group B patients required 34% fewer transfusions during induction and 15.5% fewer during consolidation (p = 0.04). There were no differences between groups regarding major bleeding episodes. INTERPRETATION AND CONCLUSIONS Our data show that the threshold for prophylactic platelet transfusion can be safely set at 10,000 microL during induction and consolidation chemotherapy for adult patients with de novo AML.

Abstract
BACKGROUND Peripheral T-cell lymphomas (PTCL) account for about 10% of all lymphomas in Western countries. The aim of the present study is to analyze the initial characteristics and prognostic factors in a large series of PTCL patients. PATIENTS AND METHODS 174 patients (105 male/69 female; median age 61 years) were diagnosed with PTCL according to the R.E.A.L. Classification in nine Spanish institutions between 1985 and 1996. Cutaneous lymphomas and T-cell chronic lymphocytic/prolymphocytic leukemia were excluded from the study. Univariate and multivariate analyses were used to assess the prognostic value of the main initial variables. RESULTS The distribution according to histology subgroup was: PTCL unspecified, 95 cases (54.4%); anaplastic large-cell Ki-l-positive (ALCL), 30 cases (17%); angioimmunoblastic T cell, 22 cases (13%); angiocentric, 14 cases (8%); intestinal T cell, 12 cases (7%), and hepatosplenic gamma delta T cell, one case (0.6%). As compared to the other types, ALCL presented more frequently in ambulatory performance status, without extranodal involvement, in early stage, normal serum beta 2-microglobulin (B2M) level and low-risk international prognostic index (IPI). Most patients were treated with adriamycin-containing regimens. The overall CR rate was 49% (69% for ALCL vs. 45% for other PTCL; P < 0.02). The risk of relapse was 48% at four years. Median survival of the series was 22 months (65 months for ALCL vs. 20 months for other PTCL; P = 0.03), with a four-year probability of survival of 38% (95% confidence intervals (95% CI): 28-48). In the univariate analysis, in addition to the histology, older age, poor performance status, presence of B-symptoms, extranodal involvement, bone marrow infiltration, advanced Ann Arbor stage, high serum LDH, high serum B2M, and intermediate- or high-risk IPI were related to poor survival. In the multivariate analysis the histologic subgroup (ALCL vs. other PTCL) (P = 0.02; response rate (RR): 4.3), the presence of B-symptoms (P = 0.02, RR: 2.2), and the IPI (low vs. high) (P = 0.04, RR: 2) maintained independent predictive value. When the analysis was restricted to the unspecified subtype, only IPI had independent prognostic value (P = 0.003; RR: 3.5). CONCLUSIONS PTCL have adverse prognostic features at diagnosis, respond poorly to therapy and have short survival, with no sustained remission. ALCL constitutes a subgroup which responds better to therapy and has a longer survival.
