Abstract
The short-term beneficial effect of hydroxyurea (HU) in sickle cell disease (SCD) has been proven by randomized studies in children and adults. The Belgian registry of HU-treated SCD patients was created to evaluate its long-term efficacy and toxicity. The median follow-up of the 93 patients registered is 3.5 years; clinical and laboratory data have been obtained for 82 patients at 1 year, 61 at 2 years, 44 at 3 years, 33 at 4 years, and 22 after 5 years. On HU, the number of hospitalizations and days hospitalized dropped significantly. Analysis of the 22 patients with a minimum of 5 years of follow-up confirm a significant difference in the number of hospitalizations (P =.0002) and days in the hospital (P <.01), throughout the treatment when compared to prior to HU therapy. The probabilities of not experiencing any event or any vaso-occlusive crisis requiring hospitalization during the 5 years of treatment were, respectively, 47% and 55%. On HU, the rate per 100 patient-years of severe events was estimated to be 3.5% for acute chest syndrome, 1.2% for aplastic crisis, 0.4% for splenic sequestration; it was 0% for the 9 patients with a history of stroke or transient ischemic attack followed for an average of 4 years. No important adverse effect occurred. Long-term chronic treatment with HU for patients with SCD appears feasible, effective, and devoid of any major toxicity; in patients with a history of stroke, HU may be a valid alternative to chronic transfusion support.

Abstract
The purine nucleoside analogs fludarabine and 2-chloro-2'-deoxyadenosine display substantial activity in the treatment of various chronic lymphoproliferative disorders. Their major toxicities are primarily immunosuppression and myelosuppression. The profound influence of these drugs on the immune system has raised questions as to the emergence of secondary neoplasms or auto-immune disorders after their use. Based on a literature review and on personal observations, this article reviews the potential clinical importance of these concerns.

Abstract
Numerous chromosome abnormalities have been described in myelodysplastic syndromes, but single karyotypic aberrations are much less frequent. We report the case of a 65-year-old woman who presented a trisomy 21 as the sole karyotypic anomaly for a refractory anemia with ring sideroblasts. The nature of such an anomaly is discussed in regard to pathogenesis and prognosis.

Abstract
We report the case of a 20 year-old caucasian woman who presented a primary subcutaneous panniculitis-like T-cell lymphoma (SPTCL) as an invasive tumor of the chest wall. Herein, the neoplastic cells were found to express a CD3+CD8+ phenotype but also displayed variably the natural killer (NK)-associated antigens CD56 and CD57 as well as granzyme B. On cytological examination, these cells showed a large granular lymphocyte (LGL)-like morphology with presence of azurophilic granules in their cytoplasm. Electron dense and membrane bound granules like those found in cytotoxic T lymphocytes (CTL) were also demonstrated by electron microscopy. Neither rearrangement of the T-cell receptor subunits nor Epstein-Barr virus (EBV) genome was observed at the molecular level. The LGL-like features of the neoplastic cells found in this case and the presence of NK-associated antigens provide additional support to the cytotoxic derivation of most SPTCL.

Abstract
We present the case of an asymptomatic HIV carrier, who presented with acute myeloblastic leukemia in third relapse and successfully underwent autologous stem cell transplantation as a rescue treatment. This observation supports the conclusion that tolerance of autologous bone marrow or stem cell transplant in patients with HIV may correlate with a low viral burden and relatively good immune function.

Abstract
A particular case of marginal zone B-cell lymphoma (MZBCL) presenting with leukemic lymphocytes is reported. In the present observation, the leukemic cells not only displayed a remarkable morphological fluctuation but also had an unusual phenotype, changing with time. These phenotypic features, which have been functionaly investigated by in vitro assays, might simply reflect an activation state depending on the microenvironment. Because of its disconcerting similarities with hairy cell leukemia (HCL) and splenic lymphoma with villous lymphocytes (SLVL), this case relaunches the debate about whether close relationships might exist between the splenic marginal zone, SLVL and HCL.

Abstract
Seventy autologous peripheral blood stem cell transplants (APBSCT) performed in 61 cancer patients were retrospectively analyzed. Patients were heterogenous with regard to malignancy, conditioning regimens and use of growth factors after transplantation. Six patients developed a non-infectious fever, fluid retention and pulmonary interstitial infiltrates during the early phase of neutrophil recovery. Diarrhea was observed in four of these patients and cutaneous rash in three. The clinical condition improved spontaneously in one patient, and within 48 h after steroid therapy in four. One patient died from multiple organ failure. Age, sex (all patients were female; P = 0.07), and time to platelet recovery did not distinguish the six courses complicated by the hypothetical engraftment syndrome (ES) from the other 64 courses taken as controls. However, neutrophil recovery > 0.5 x 10(9)/l occurred earlier (P = 0.01), and the neutrophil count increment during the early phase of recovery was steeper in ES patients (P = 0.003). ES was also associated with infusion of a high number of CD34+ progenitors (P = 0.03) and conditioning with busulfan (P = 0.03). Although all ES patients received G-CSF after transplantation, an association of ES with G-CSF use could not be demonstrated, possibly because of the small number of courses not supported by G-CSF. However, in one patient, ES did not recur after a second transplant unsupported by growth factors. Our study supports the idea of an engraftment syndrome associated with an early and steep neutrophil recovery after APBSCT.

Abstract
The immunological detection of P-Glycoprotein (P-GP) and the functional release of Rhodamine 123 (R123) have been compared in a number of human and murine cancer cell lines, in chemo- and/or radiotherapy-resistant subclones, and in clinical specimens from patients. The chemoresistance level was established from the viability index (IC50) in the presence of doxorubicin. Cytocentrifuge preparations were immunostained with JSB-1 monoclonal antibody followed by the alkaline phosphatase anti-alkaline phosphatase technique. The strength of the reaction was quantified by a digital image analyser. The kinetic incorporation and release of Rhodamine 123 were evaluated by flow cytometry. The parent cell lines and radiotherapy resistant subclones showed a low IC50, were JSB-1 negative and retained R123 during the whole experiment, while the chemoresistant and radio-chemoresistant cell line mutants had a high IC50, were JSB-1 positive, and actively pumped the R123 out of the cells. Good correlations were obtained between the IC50, the digital image analysis, and flow cytometry. The kinetic profile of the R123 release allowed the distinction between typical and atypical multidrug resistance phenotypes. These findings were confirmed in clinical specimens from patients. We conclude that antigenic and functional studies are complementary and are useful in experimental and clinical approaches to multidrug resistance.

Abstract
PHA-stimulated human lymphocytes or myelogenous leukemia cells (strain K-562) were pulse labeled with 3H-thymidine and submitted to various fixation-permeabilization procedures. They were then immunostained with the 19A2, 19F4 or PC10 monoclonal antibody against the proliferating cell nuclear antigen (PCNA). The preparations were finally scored for the proportion of unlabeled, double-labeled and single PCNA or 3H-thymidine-labeled nuclei. Unstimulated lymphocytes were immunonegative in all the conditions tested, as also were stimulated lymphocytes checked with an isotype of the primary antibody. A specificity (Sp) and a sensitivity (Se) score was calculated to evaluate the recognition by PCNA staining of the S-phase cells, as defined by the 3H-labeling. The data show that in most instances the three antibodies recognized the 3H-labeled cells with high sensitivity, ie with few false negative, but with low specificity, ie with PCNA positivity extending to variable proportions of non-S-phase cells. By contrast, methanol fixation followed by a brief treatment with the detergent Triton X-100 and immunostaining with either 19F4 or PC10 (but not with 19A2) combined a high sensitivity and specificity scores of the recognition of the 3H-thymidine-labeled cells: PC10 gave a more intense and, hence, more readable reaction. PHA-stimulated lymphocytes that had been preserved at -20 degrees C as cytocentrifuged smears failed to show any immunopositivity for PCNA if not submitted to further fixation prior to the immunocytochemical assay. When methanol-Triton was used for this step, only PC10 gave positive immunoreaction, yet with a lower specificity score (Sp = 76%) than in cells submitted to this fixation-permeabilization procedure without prior cryopreservation (Sp = 91.7%). The PCNA index was measured in cryopreserved, methanol-fixed smears of lymphocytes from patients with various hematological diseases and was compared to the Ki-67 index established independently on a serial sample. A good correlation was found between the two indices (r = 0.79; P < 0.0001) with the PCNA index generally lower than or close to the Ki-67 index. This warrants a note of caution about the use of total (ie stable and labile) PCNA immunostaining to measure the growth fraction (GF), classically defined as the proportion of proliferating cells in a population. However, in the absence of an absolute reference marker for G0 cells, there is no reason to assume that the PCNA index would necessarily be a worse estimate of GF than the Ki-67 index.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
A recent randomized multicentric French study has shown that intensification with stem cell rescue improves the response rate and progression-free survival in multiple myeloma. Transplantation with primed peripheral blood stem cells (PBSC) displays a faster hematological recovery, especially for platelets, as compared with a bone marrow stem cell graft. In multiple myeloma, the optimal mobilization method for PBSC is unknown. The present study compares mobilization with cyclophosphamide 4 g/m2 + G-CSF 5 micrograms/kg versus G-CSF 5 micrograms/kg alone versus G-CSF 10 micrograms/kg alone in two cases of multiple myeloma, using an intrapatient controlled evaluation of the amount of CD34-positive cells obtained during each leukapheresis. In both cases, the highest CD34-positive cells yield was obtained with G-CSF at 10 micrograms/kg. Despite the low number of cases, this method, devoid of life-threatening toxicity, might be of greatest interest in multiple myeloma.

Abstract
The authors report two patients with characteristic features of chronic neutrophilic leukemia (CNL) treated with alpha-2b-interferon (IFN) (Schering-Plough). At initiation of therapy, both patients had progressive disease and presented with large tumors. A rapid reduction of the tumor mass and a long-term stabilisation of the myeloproliferative disorder was obtained (therapy duration 16 and 26 months, respectively, and presently ongoing). In one patient, the dose of IFN could be significantly reduced during maintenance without relapse. Neither presented infectious or hemorrhagic complications under therapy. Alpha-2b-interferon is active and safe in CNL, even pretreated and progressive. It can also correct the neutrophil and natural killer functional defects frequently observed in CNL.

Abstract
Increments in serum ferritin levels in adult onset Still's disease (AOSD) were reported to be higher than one could expect for a simple inflammatory state. When we analyzed the scores of 40 patients with various severe inflammatory diseases aside from AOSD, we recorded no serum ferritin values higher than 3,300 ng/ml (N less than 200 ng/ml). In 3 of 10 consecutive patients with AOSD, the ferritin levels were higher than 3,500. Among these 3 patients, one case had a ferritin value of 3,600 ng/ml and bone marrow aspirate showed a marked hyperplasia of mature appearing histiocytes, and the 2 other patients (serum ferritin levels of 65,000 ng/ml and 250,000 ng/ml) displayed the features of a hemophagocytic syndrome. In 2 patients with normal or mildly increased levels of ferritin, the bone marrow examination was normal. We suggest that very high serum ferritin levels encountered in AOSD reflect the presence of histiocytic hyperactivity that sometimes leads to a hemophagocytic syndrome.

Abstract
Bone marrow scintigrams (MS) combined with single photon emission computed tomographic investigation of the liver (liver SPECT) were obtained using 99Tcm-labelled human serum albumin nanosized colloids in 52 patients with histologically proven lung carcinomas (adenocarcinomas = 17, squamous cell = 16, small cell = 14, large cell = 5, 31 generalized cases at the time of the first MS investigation among whom 13 patients had proven skeletal metastases). They were compared with conventional bone scintigrams (BS) as well as clinical, biological, radiological and follow-up data obtained for the same patients. In the present series, MS appeared as sensitive as BS in diagnosing skeletal metastases (77%) if all abnormal MS and BS presentations are considered as diagnostic, but more sensitive (77% versus 54%) if more restrictive analytical criteria are applied. The two investigations yielded the same specificities whatever the analytical criteria applied. These preliminary conclusions have, however, to be confirmed on larger populations than the present series. The most striking differences between BS and MS were observed in the case of small-cell lung carcinomas, with more lesions detected by MS than by BS. Liver SPECT also made it possible to diagnose seven and to suspect one out of the ten situations of hepatic metastases. The combination of liver spect and MS in the framework of a single injection of 99Tcm-labelled nanosized colloids thus allowed us to diagnose 80% of the patients with osseous and/or hepatic metastasis or 40% of all generalized cases.

Abstract
We report the findings in 21 Belgian patients (12 males and 9 females, median age 61 years) with LGLPD. Symptoms at presentation included infection (n = 9), weight loss (n = 5), asthenia (n = 9), pruritus (n = 2) and arthralgia (n = 7). Four patients were asymptomatic. The main clinical findings were hepatomegaly (n = 5), splenomegaly (n = 8), lymph node enlargement (n = 3) and arthritis (n = 5). All patients had an increased LGL count associated with anemia (n = 12), neutropenia (n = 17), often less than 0.5.10(9)/L (n = 10) and thrombocytopenia (n = 6). Three patterns of lymphocyte surface markers were observed: CD3+CD4-8+ (14 patients), CD3+CD4-8+ (5 patients) and CD3+CD4+8- (1 patient). An abnormal karyotype was found in 2 patients. T-cell receptor gene was rearranged in all cases tested (9/9).

Abstract
Anticardiolipin antibodies (ACA) and lupus-like anticoagulant (LLAC) have been studied in a group of 142 non-hospitalized and a group of 72 hospitalized HIV infected patients. We observed a variable frequency of ACA positivity ranging from 7.7% to 30.3% according to the groups of patients and the isotype of immunoglobulin fraction containing ACA activity. None of the patients investigated presented a prolongation of the activated partial thromboplastin time (APTT) compatible with the presence of a LLAC. Some patients presented a weak anticoagulant activity only detected by the tissue thromboplastin inhibition (TTI) test. No positive correlation was found between this latter test and ACA. We conclude that, like in syphilitic patients, ACA present in HIV infected patients are most often not associated with LLAC.

Abstract
Tumor cells of 14 cases of non-Hodgkin lymphomas and 2 cases of Hodgkin disease were tested for the presence of the transferrin receptor (CD71) by flow cytofluorimetry before 67gallium imaging. It appeared that expression of CD71 phenotype was closely related to the positivity of gallium scan before therapy. We feel that this test is able to predict the avidity for 67gallium and the clinical implications are discussed.
