Abstract
OBJECTIVE To conduct a long-term, prospective, randomized controlled trial evaluating rituximab (RTX) therapy for severe mixed cryoglobulinemia or cryoglobulinemic vasculitis (CV). METHODS Fifty-nine patients with CV and related skin ulcers, active glomerulonephritis, or refractory peripheral neuropathy were enrolled. In CV patients who also had hepatitis C virus (HCV) infection, treatment of the HCV infection with antiviral agents had previously failed or was not indicated. Patients were randomized to the non-RTX group (to receive conventional treatment, consisting of 1 of the following 3: glucocorticoids; azathioprine or cyclophosphamide; or plasmapheresis) or the RTX group (to receive 2 infusions of 1 gm each, with a lowering of the glucocorticoid dosage when possible, and with a second course of RTX at relapse). Patients in the non-RTX group who did not respond to treatment could be switched to the RTX group. Study duration was 24 months. RESULTS Survival of treatment at 12 months (i.e., the proportion of patients who continued taking their initial therapy), the primary end point, was statistically higher in the RTX group (64.3% versus 3.5% [P < 0.0001]), as well as at 3 months (92.9% versus 13.8% [P < 0.0001]), 6 months (71.4% versus 3.5% [P < 0.0001]), and 24 months (60.7% versus 3.5% [P < 0.0001]). The Birmingham Vasculitis Activity Score decreased only after treatment with RTX (from a mean ± SD of 11.9 ± 5.4 at baseline to 7.1 ± 5.7 at month 2; P < 0.001) up to month 24 (4.4 ± 4.6; P < 0.0001). RTX appeared to be superior therapy for all 3 target organ manifestations, and it was as effective as conventional therapy. The median duration of response to RTX was 18 months. Overall, RTX treatment was well tolerated. CONCLUSION RTX monotherapy represents a very good option for severe CV and can be maintained over the long term in most patients.

Abstract
Background To develop preliminary classification criteria for the cryoglobulinaemic syndrome or cryoglobulinaemic vasculitis (CV). Methods Study part I developed a questionnaire for CV to be included in the formal, second part (study part II). Positivity of serum cryoglobulins was defined by experts as an essential condition for CV classification. In study part II, a core set of classification items (questionnaire, clinical and laboratory items, as agreed) was tested in three groups of patients and controls—that is, group A (new patients with the CV), group B (controls with serum cryoglobulins but lacking CV) and group C (controls without serum cryoglobulins but with features which can be observed in CV). Results In study part I (188 cases, 284 controls), a positive response to at least two of three selected questions showed a sensitivity of 81.9% and a specificity of 83.5% for CV. This questionnaire was employed and validated in study part II, which included 272 patients in group A and 228 controls in group B. The final classification criteria for CV, by pooling data from group A and group B, required the positivity of questionnaire plus clinical, questionnaire plus laboratory, or clinical plus laboratory items, or all the three, providing a sensitivity of 88.5% and a specificity of 93.6% for CV. By comparing data in group A versus group C (425 controls), the same classification criteria showed a sensitivity 88.5% and a specificity 97.0% for CV. Conclusion Classification criteria for CV were developed, and now need validation.

Abstract
Autoimmune thrombocytopenia (AITP) is a disorder due to specific platelet auto-antibodies directed against platelet surface glycoproteins. AITP in adults is usually chronic, idiopathic and frequently refractory to conventional treatments. Myelo- and immuno-suppressive chemotherapy followed by autologous peripheral blood stem cell (PBSC) transplantation is an experimental approach for severe chronic refractory AITP. We report a case of a woman with AITP, refractory to the conventional therapy, submitted to T-cell-depleted autologous PBSC transplantation, which obtained long term stable response on platelet count. We deem that the positive outcome of our patient depends on T-cells depletion of the graft, which reduces autoreactive T clones.

Abstract
BACKGROUND AND AIMS Information on the impact of therapeutic strategies of hepatocellular carcinoma is still incomplete due to the lack of surveys involving primary-care centres. PATIENTS AND METHODS The Gruppo Epatologico Lombardo (GEL) carried out a study on 361 incident hepatocellular carcinoma observed from January to December 1998 in 22 hospitals in Lombardy. The clinical, pathological and therapeutic data were collected from all patients; 5-year survival and factors related to outcome were analysed. RESULTS Two hundred and ninety-seven patients were male (M/F: 4.6/1, mean age 66); 61% were HCV-pos, 15% HBV-pos, 17% alcoholic. Cirrhosis was present in 333 (92%) and was classified as Child-A in 197 (59%), Child-B in 85 (26%) and Child-C in 51 (15%) cases. Hepatocellular carcinoma was multifocal/diffuse (more than three nodules) in 91 (25%), less than three nodules in 86 (24%) and monofocal in 184 (51%) (</=3cm in 146). As to the therapy: 145 hepatocellular carcinomas (40%) were untreated, 78 (22%) underwent percutaneous ethanol injection/radiofrequency ablation, 75 (20%) transarterial chemoembolization, 32 (9%) liver resection and 3 (0.8%) ortothopic liver transplantation (OLT). Survivals at 1, 3 and 5 years were 75%, 27% and 13%, respectively. Child-Pugh score, small size of the tumour and treatment, regardless of the type, were independent predictors of better prognosis. CONCLUSION This prospective, region-wide, cohort study showed that the characteristics of hepatocellular carcinoma in Lombardy (1998) do not differ from those reported in previous Italian surveys. Although most hepatocellular carcinomas were discovered at a relatively early stage, a large part remained untreated and the overall prognosis was poor. Efforts are warranted to implement screening-surveillance programmes and the impact of therapeutic strategies.

Abstract
BACKGROUND Interferon-induced depression ranges from 0 to 50%. Interferon schedule and a history of psychiatric illnesses are not enough to predict who will develop symptoms and who will not. AIMS To assess the prevalence of depression during interferon therapy; to test whether Minnesota Multiphasic Personality Inventory is useful in clinical practice for the early identification of patients at risk of depression; whether and how the depression can be cured. PATIENTS One hundred and eighty-five patients treated with interferon and ribavirin for chronic hepatitis C. METHODS Before therapy, all patients underwent a Minnesota Multiphasic Personality Inventory and a clinical examination, specifically for the identification of depressive symptoms. RESULTS Thirty-one patients developed a psychiatric disorder, 11 of them requiring treatment with anti-depressant drugs. Among the 18 patients with Minnesota Multiphasic Personality Inventory positive tests, 16 developed a psychiatric disorder, 8 of them a severe disorder (sensitivity of 0.58; 0.73 for severe disorders). Among the 154 who did not develop psychiatric side effects, 152 had a negative Minnesota Multiphasic Personality Inventory (specificity: 0.99). Severe psychiatric disorders were successfully treated with anti-depressant drugs. CONCLUSIONS Psychiatric side effects are easy to see during interferon therapy. A psychiatric evaluation should be considered on all patients before treatment. If depression develops, it should be treated aggressively, and selective serotonin re-uptake inhibitors are the anti-depressants of choice.

Abstract
Autologous peripheral blood stem cell (PBSC) transplantation proved to increase complete remission (CR) and DFS in multiple myeloma (MM) patients. CD34(+) cell selection has been used to reduce possible myeloma cell contamination in the graft, but it has not been showed to offer substantial advantages when compared to unpurged grafts; on the contrary, an increase of infectious complications was observed. We investigated the feasibility of a new negative-selection method in this setting. B cell negative selection was performed by using Eligix B cell HDM method. B cell contamination in the yield and in the final product was investigated by flow cytometry. Three patients with newly diagnosed MM entered the study. CD34(+) cell recovery in the three procedures was 73, 97, and 106%, and CD3(+) cell recovery was 88, 86, and 102%, respectively. CD20(+) cell depletion was 100% in all procedures, while CD19(+) cell depletion was 0.37, 1.21, and 0.07 log, respectively. We found an unexpected unreliability and a low efficiency in this B cell depletion method and suggest the need for further extensive testing before its introduction in the preclinical and clinical settings, at least in MM patients. In fact, reasons of such unsatisfactory results are still controversial: platelet contamination/activation in the preselection product, plasma protein interference, reduced CD19 antigen expression on immature B cells, lack of specificity of anti-CD19 monoclonal antibodies, instable binding between anti-CD19-coated high-density microparticles (HDM) and CD19 antigen may, alone or in combination, be involved in the system's low performance.

Abstract
We retrospectively analyzed red blood cell (RBC) support and alloimmunization rate in 218 consecutive patients - 128 from the Pediatric Department and 90 from the adult Hematology Department - undergoing hematopoietic stem cell transplantation (HSCT) between 1994 and 2000. In the pre-HSCT period, the pediatric patients undergoing auto-HSCT required more RBC support. In the post-HSCT period, pediatric patients transplanted with an unrelated donor required more RBC support (median 13.5 U/10 kg bw) than patients receiving HSCT from a related donor (median 6 U/10 kg bw) or from an autologous source (median 4 U/10 kg bw, P=0.0004). In the pre-HSCT period, 159 out of 218 patients (73%) received a total of 1843 RBC units, with an overall median of 9 U/patient over a median of 24 months (range 4-62); 10 patients (6%) developed a total of 12 alloantibodies, with an alloimmunization rate of 5.4/1000 RBC units. In the post-HSCT period, all but three patients were given a total of 2420 RBC units, with an overall median of 6 U/patient over a median of 4 months (range 1-18); all but one of the pre-existing alloantibodies disappeared and three patients (1%) developed new alloantibodies with an alloimmunization rate of 1.2/1000 RBC units. These newly produced alloantibodies (one anti-M and two anti-E) were detected at +58, +90 and +210 days after HSCT. These findings might suggest a different approach to alloantibody screening tests in patients receiving HSCT, with a subsequent reduction of costs and laboratory workload.

Abstract
OBJECTIVE To assess the influence of hepatitis C virus (HCV) genotypes on the clinical outcome of liver disease, we analysed 2,307 patients. RESULTS The most frequently represented genotypes were 1b (40%) and 2 (28.1%). Patients with these genotypes had a median age higher than patients with other genotypes (P< 0.01). The overall survival of subjects with genotype 1b was poorer than the survival of patients with other genotypes (P< 0.01). Liver cirrhosis was found in 280 patients (12.1%), and type 1b was the most represented isolate among them (P< 0.01). Sixty-two patients (22%) developed hepatocellular carcinoma (HCC) during a follow-up of 1481.8 cumulative years (estimated crude incidence rate, 4.1 cases per 100 person-years for all cirrhotics; 5.9 cases for genotype 1a; 4.5 cases for genotype 1b; and 2.8 cases for genotypes non-1). Considering the whole population of 2,307 patients, only genotype 1b was associated significantly with both cirrhosis and the development of HCC. One hundred and nineteen cirrhotic patients underwent treatment with interferon in uncontrolled studies. Interferon therapy was associated with both better survival (P< 0.01) and a lower cumulative hazard for HCC (P< 0.01). CONCLUSIONS Genotype 1b was associated with a poorer prognosis, probably because it leads to cirrhosis and consequently to HCC development. However, our data did not confirm genotype 1b as an independent risk factor for HCC in liver cirrhosis, which plays a major role in carcinogenesis. Interferon should be considered as a useful strategy in cirrhosis for improvement of survival and reduction of HCC risk.

Abstract
STI571 (CGP57148B) is an inhibitor of BCR/ABL, the cause of chronic myeloid leukaemia (CML). A difference exists between CML patients in chronic phase, in which responses to STI571are durable, and patients in blast crisis, who generally experience only transient responses. Leukaemic cells from six CML patients from whom samples could be obtained during chronic phase and at the time of blast crisis (BC) were compared for sensitivity to STI571, using an in vitro assay. BC samples showed a sensitivity similar to that obtained during chronic phase, suggesting that no substantial intrinsic resistance to STI571 was present in BC.

Abstract
BACKGROUND AND OBJECTIVES Even though the risk of pneumonia is higher in patients with advanced disease, the potential risk of death is particularly relevant during induction therapy, when patients can be potentially cured of their hematologic disease: our study was aimed at evaluating the risk and outcome of pneumonia in these patients. DESIGN AND METHODS We retrospectively studied all 458 patients affected by acute leukemia receiving an anthracycline-containing induction regimen in the years 1984-1989. RESULTS Of the 458 patients, 109 (23.8%) developed pneumonia: 91 had acute myelogenous leukemia (AML) and 18 had acute lymphoblastic leukemia (ALL). At univariate analysis, advanced age, AML and total blast count significantly correlated with the risk of pneumonia. At multivariate analysis, only age (p< 0.0001) and total blast count (p=0.002) retained their prognostic significance. Pneumonia responded to treatment in 67 (61.5%) patients, while 42 (38.5%) patients died. Among patients with pneumonia, 51 (46.8%) patients achieved a complete remission: 9/18 ALL and 42/91 AML. At univariate analysis, the most significant determinant of a positive outcome was the achievement of complete remission; a higher absolute neutrophil count at the onset of pneumonia, the absence of rales, a single infiltrate and the absence of microbiological demonstration of infection were also related to a positive outcome. At multivariate analysis, the achievement of complete remission and, with borderline significance, a single infiltrate maintained their prognostic value. INTERPRETATION AND CONCLUSIONS Pneumonia remains one of the most relevant risks of morbidity and mortality during induction therapy for acute leukemia. A fatal outcome is associated, in most cases, with a failure to achieve remission of leukemia.

Abstract
BACKGROUND Chronic myeloid leukemia is caused by a chromosomal translocation that results in an oncogenic fusion protein, Bcr-Abl. Bcr-Abl is a tyrosine kinase whose activity is inhibited by the antineoplastic drug STI571. This drug can cure mice given an injection of human leukemic cells, but treatment ultimately fails in animals that have large tumors when treatment is initiated. We created a mouse model to explore the mechanism of resistance in vivo. METHODS Nude mice were injected with KU812 Bcr-Abl(+) human leukemic cells. After 1 day (no evident tumors), 8 days, or 15 days (tumors >1 g), mice were treated with STI571 (160 mg/kg every 8 hours). Cells recovered from relapsing animals were used for in vitro experiments. Statistical tests were two-sided. RESULTS Tumors regressed initially in all STI571-treated mice, but all mice treated 15 days after injection of tumor cells eventually relapsed. Relapsed animals did not respond to further STI571 treatment, and their Bcr-Abl kinase activity in vivo was not inhibited by STI571, despite high plasma concentrations of the drug. However, tumor cells from resistant animals were sensitive to STI571 in vitro, suggesting that a molecule in the plasma of relapsed animals may inactivate the drug. The plasma protein alpha1 acid glycoprotein (AGP) bound STI571 at physiologic concentrations in vitro and blocked the ability of STI571 to inhibit Bcr-Abl kinase activity in a dose-dependent manner. Plasma AGP concentrations were strongly associated with tumor load. Erythromycin competed with STI571 for AGP binding. When animals bearing large tumors were treated with STI571 alone or with a combination of STI571 and erythromycin, greater tumor reductions and better long-term tumor-free survival (10 of 12 versus one of 13 at day 180; P:<.001) were observed after the combination treatment. CONCLUSION AGP in the plasma of relapsed animals binds to STI571, preventing this compound from inhibiting the Bcr/Abl tyrosine kinase. Molecules such as erythromycin that compete with STI571 for binding to AGP may enhance the therapeutic potential of this drug.

Abstract
It is widely thought, but not yet explained, that there might be a pathogenetic link between the infection of hepatitis C virus (HCV) and the onset of B non-Hodgkin's lymphoma (NHL). We studied the prevalence of serum anti-HCV antibodies among 300 NHL comparing it with the prevalence among 600 age- and sex-matched non-neoplastic subjects as controls, 247 patients with non-lymphomatous neoplasm, and 122 patients treated with immunosuppressive agents. We found a prevalence of 0.16 among NHL and 0.085 among controls and non-lymphomatous patients. Although the difference was statistically significant (P < 0.001), the odds ratio was 2.049 and its confidence intervals included the equality. The HCV prevalence was independent of NHL subset, and the genotypes distribution was the same among NHL and controls. We disclosed a HBsAg prevalence of 0.077 in NHL versus 0.008 in controls (P < 0.001) with an odds ratio of 9.9. We do not believe that these findings support the hypothesis of an HCV pathogenetic role in lymphomagenesis because (i) the risk of previous infection is marginally higher in NHL than in controls, (ii) a typical genotype distribution is lacking, as is a NHL clinico-histological feature associated with HCV, and (iii) the higher prevalence of viral infection is not specific as witnessed by the high HBsAg prevalence.

Abstract
In recent years peripheral blood stem cell (PBSC) collection for allogeneic or autologous transplantation has experienced an increased use in the onco-hematological setting. The latest generation cell separators allow a satisfactory and safe PBSC collection. Nevertheless, as in all therapeutic apheresis procedures, patients may experience procedure-related side-effects, mainly vasovagal reactions or symptoms related to hypocalcemia and/or hypomagnesemia. We investigated electrolyte changes in 18 patients, with a median age of 46 years (range 7-62), undergoing PBSC collection from January to April 1998. A significant decrease in total calcium in the final sample (9.65 +/- 0.7 mg/dL) with respect to the basal one (9.2 +/- 0.6 mg/dL, P < 0.05) was observed; also ionized calcium decreased markedly from the first sample drawn at +30 minutes: 1.22 +/- 0.14 vs. 1.03 +/- 0.15 mmol/L (P < 0.05), and a highly significant difference emerged when basal value were compared to the final value: 1.22 +/- 0.14 vs. 0.94 +/- 0.13 mmol/L (P < 0.0001). Similar findings affected potassium concentration: 4.1 +/- 0.4 vs. 3.3 +/- 0.3 mEq/L (P < 0.0001). Three out of eighteen patients (16.7%) reached a final potassium level <3.0 mEq/L, and eight out of eighteen (44.5%) showed a potassium concentration decrease >20% with respect to the basal value. A mild metabolic alkalosis occurred during the procedure: pH increased from 7.35 +/- 0.02 to 7.43 +/- 0.028 (P < 0.001), and plasma bicarbonate concentration increased from 27.48 +/- 2.21 to 32.44 +/- 2.52 mmol/L (P < 0.01). Sodium and chloride did not differ in the final sample with respect to the basal sample. None of our patients experienced clinically relevant side effects related to severe electrolyte changes (i.e., >20% with respect to the basal value). Because our current therapeutic schedules include patients older than 50 years in the PBSC collection and transplantation program and since it is well known that subclinical myocardial disease may occur in up to 4% of middle-aged males, we suggest that patients aged 50 or older undergoing PBSC collection procedures be carefully monitored in order to identify significant electrolyte variation, especially if they present with low serum potassium levels. However, further investigation of larger patient series are needed to determine the clinical relevance of serum potassium changes during apheresis.

Abstract
OBJECTIVES At the doses used for the treatment of chronic viral hepatitis, interferon (IFN)-related side-effects are usually modest, even though in some cases they require the interruption of therapy. Neuropsychiatric disturbances that range from modest depression and irritability to forms of manic-depressive psychosis and attempted or successful suicides are among the most important side-effects. The aim of our study was to determine whether the Minnesota Multiphasic Personality Inventory (MMPI) is a sensitive and reliable test for the early identification of patients at risk of depression before IFN therapy is commenced, and whether it could be useful for the monitoring of these patients during treatment. METHODS We prospectively studied 67 patients with chronic active liver diseases, consecutively enrolled in open studies and treated with r-IFNalpha2. Before starting therapy and after 3 months of treatment, all patients underwent a clinical neurological evaluation and MMPI. RESULTS At baseline, the correlation between the clinical evaluation and the score of the depression scale of the MMPI was statistically significant (P< 0.0001). Nine of 14 (64.3%) patients with a baseline score > or = 60/100 showed a depressive mood after 3 months of therapy. Five of 44 patients (11.3%) with a baseline score < 60/100 showed a depression of medium level after 3 months of treatment. This difference was highly significant (P< 0.0001). CONCLUSIONS According to our results, the MMPI is a reliable and sensitive test for the early identification of patients at risk of depression before and during IFN therapy for chronic viral liver diseases.

Abstract
The BCR/ABL oncogenic fusion protein transforms normal bone marrow stem cells into neoplastic cells. It has been shown that peptides derived from the junctional region of this oncogenic fusion protein can be recognized by human T-lymphocytes obtained from normal donors. In this study, we investigated the immunogenicity in patients with chronic myeloid leukemia (CML) of a 17 mer b3/a2 Bcr/abl peptide (B/A1), which was shown to induce proliferative responses in lymphocytes from normal donors. A total of 56 CML patients in chronic phase were studied. Twenty-two patients were studied at diagnosis without any treatment (group I). Fourteen patients were receiving IFN (group II), 14 patients were being treated with hydroxyurea (group III), and 6 patients were on different regimens (group IV). Patients were initially assessed for general immunological competence using both in vivo and in vitro assays. Patients were also selected for the expression of HLA-DR0401, the HLA specificity known to present peptide B/A1 to CD4 lymphocytes. With the exception of the six patients in group IV, the results of all these assays (in vitro phytohemagglutinin/tetanus toxoid responses, in vivo skin reaction to ubiquitous antigens) in CML patients did not significantly differ from those obtained in normal donors, thus excluding the presence of generalized immunosuppression. Eight patients with HLA-DR0401 and a b3/a2 type of fusion were identified and further studied. In these eight patients dendritic cells were obtained from adherent peripheral blood mononuclear cells and used to stimulate CD4 lymphocytes. No patient developed a specific response to the bcr/abl peptide, although patients' lymphocytes proliferated in response to a promiscuous tetanus toxoid peptide in all but one case. In contrast, response to the bcr/abl peptide was observed in seven of eight HLA-DR0401 healthy donors tested. These data suggest that immunocompetent, HLA-DR0401+ CML patients are unable to respond to peptide B/A1, at difference from healthy donors. The implication of these results for the immunotherapy of CML is discussed.

Abstract
Thrombotic thrombocytopenic purpura (TTP) is a common illness characterized by platelet thrombi within the microvascularization. In its natural course, this disease has had a mortality rate of 90%. Plasma infusion or exchange achieved a survival rate of 70% to 90%. However, 10% to 30% of patients surviving the initial TTP episode relapse at regular intervals. The treatment of recurrent forms of the disease remains a challenge; several approaches have been shown to induce medium to long term remissions. We describe a patient with recurrent TTP whose disease remitted after administration of defibrotide.

Abstract
The Ets variant gene 6 (ETV6/TEL) gene is rearranged in the majority of patients with 12p13 translocations fused to a number of different partners. We present here a case of acute myeloid leukemia M4 with eosinophilia (AML-M4Eo) positive for the CBFb/MYH11 rearrangement and carrying a t(1;12)(q25;p13) that involves the ETV6 gene at 12p13. By 3'rapid amplification of cDNA ends-polymerase chain reaction (3'RACE-PCR), a novel fusion transcript was identified between the ETV6 and the Abelson-related gene (ARG) at 1q25, resulting in a chimeric protein consisting of the HLH oligomerization domain of ETV6 and the SH2, SH3, and protein tyrosine kinase (PTK) domains of ARG. The reciprocal transcript ARG-ETV6 was also detected in the patient RNA by reverse transcriptase-polymerase chain reaction (RT-PCR), although at a lower expression level. The ARG gene encodes for a nonreceptor tyrosine kinase characterized by high homology with c-Abl in the TK, SH2, and SH3 domains. This is the first report on ARG involvement in a human malignancy.

Abstract
BACKGROUND/AIMS Hepatitis C virus (HCV) easily undergoes genomic changes, thus accounting for the presence of different genotypes, with different geographic distributions and different outcomes of chronic hepatitis. Type 1b is frequently found in advanced diseases; however, since this genotype is the most prevalent in older patients, the association with advanced age and severity of the disease is confounding. The aim of this study was to assess changes in the prevalence of HCV genotypes by surveying a large population of chronic hepatitis C patients in Northern Italy, and to assess if the high prevalence of genotype 1b in older patients with advanced diseases simply reflects the duration of HCV infection, rather than intrinsic biological properties of HCV. METHODS We studied 1368 HCV-RNA positive patients, with histologically proven chronic hepatitis. Drug addiction, blood transfusions and sporadically acquired infections represented the risk factors. RESULTS Genotype 1b, the most prevalent isolate, and genotype 2a were associated with older age, cirrhosis, sporadically-acquired infections and blood transfusion, while types 1a, 3a, and 4 were associated with younger age, chronic persistent hepatitis and drug addiction. Patients with a history of transfusions were divided into four groups depending on the period of transfusion. The prevalence of genotype 1b decreased with time. Type 3a appeared only after 1979. CONCLUSION The severity of chronic hepatitis C could be related more to the duration of the infection rather than to the intrinsic pathogenicity of HCV genotypes.

Abstract
OBJECTIVE We compared the efficacy of interferon and deflazacort in the treatment of the cryoglobulinaemic syndrome and assessed the usefulness of adding a low antigen diet to drug therapy. METHODS We studied 63 patients randomly allocated to different groups who underwent clinical and laboratory examinations every two months and who received treatment for 12 months or until a significant clinical event appeared. RESULTS Five of 28 patients treated with interferon showed clinical improvement whereas 4 worsened and 7 suffered untoward side effects; seven of 28 patients treated with deflazacort improved, 4 worsened and 4 suffered drug toxicity. Twenty-nine patients were assigned to combined low antigen diet and therapy, among whom 7 did not follow the diet, 5 improved and 2 worsened. Among the 34 patients who were on an unrestrained diet, 5 improved and 7 worsened. None of the treatments proved superior to the others. CONCLUSION Our results do not confirm the suggestion that interferon should be the primary therapy in the treatment of the cryoglobulinaemic syndrome, and the usefulness of a low antigen diet seems minimal.

Abstract
OBJECTIVE The cryoglobulinemic syndrome (CS) may be associated with other diseases; when it is not, it is termed essential. Recently the natural history of this disease has been re-evaluated on the basis of its close association with HCV markers. In this context, the GISC has studied a large series of patients from several Italian centres. METHODS In a multicentric retrospective study of 913 cases, we evaluated the clinical and laboratory signs at onset in patients with essential mixed cryoglobulinemias (EMC) (654 cases) or secondary cryoglobulinemias (SC) (259 cases) and sought to define possible diagnostic criteria typical of the different CS. We also carried out a retrospective 5-year cohort study on 192 patients selected randomly from the 913 cases described above. In particular, we examined the correlation between the presence/absence of concomitant diseases and the presence of HCV markers on the clinical evolution and survival of the patients. RESULTS Purpura, rheumatoid factors (RF), significant C4 consumption, and Brouet's classification type II were more frequent in EMC. Purpura, Meltzer's triad, and Raynaud's phenomenon improved, while renal involvement tended to worsen over time. During the follow-up we did not note a significant change in clinical staging in the patients with Brouet's type II cryoglobulins, in the patients with HCV-related markers, or in the overall series. The most frequent causes of death in 34 patients were liver, cardiovascular, renal, and lymphoproliferative diseases. Lymphomas were diagnosed in 11 patients during follow-up, with particular frequency in the HCV-marker positive patients. CONCLUSION Specific clinical and laboratory features typical of the different CS subgroups could not be identified on the basis of these data. Our follow-up data seem, however, to confirm a role for HCV in the mixed cryoglobulinemias.

Abstract
Nine consecutive patients with essential mixed cryoglobulinaemia type II (EMCII) were investigated by a follow-up study of 3-6 years (mean 5.3), to verify the long-term outcome of the peripheral nerve involvement in the disease. At the beginning of the study, a peripheral neuropathy, mild or moderate, mainly sensory, was present approximately in 50% of cases. All patients maintained good general conditions, low-staging of EMCII, were well controlled by therapy or did not need any medical treatment. During the neurological follow-up all patients had regular controls, usually at 1-year intervals, and only slight changes were seen with respect to the first evaluation. Therefore, we conclude that peripheral neuropathy during EMCII is less progressive that it can be thought at least in patients with benign course of the disease.

Abstract
OBJECTIVE We investigated the presence of anti-GOR antibodies in patients with essential mixed cryoglobulinemia, since both autoimmune pathogenetic processes and a high prevalence of HCV infection are present in this syndrome. METHODS We compared these cases to patients with HCV-related chronic active hepatitis or alcoholism, and to ex-blood donors. A total of 60 patients with biopsy-proven chronic liver disease were studied. RESULTS HCV related markers, cryoglobulins, anti-GOR antibodies and ANA were detected in all of the groups. CONCLUSION Our data would appear to indicate that anti-GOR are related to the presence of HCV chronic hepatitis and not to cryoglobulinemia or chronic liver damage.

Abstract
Fifteen patients with a primary myelodysplastic syndrome (MDS) transformed into acute myeloblastic leukemia (AML) were treated with an intensive chemotherapy regimen containing idarubicin. A complete response (CR) was obtained in 10 patients (66.6%). In five of them this was achieved after a single course of chemotherapy. The median time to achieve a CR was 32 days (range 16-42). A partial remission (PR) was obtained in 2 patients after two induction courses of chemotherapy. One patient died during the first induction course following acute respiratory distress syndrome (ARDS) complication, whereas the chemotherapy regimen failed in 2 patients. A short interval between MDS and transformation into AML was associated with a better chance of achieving a CR. Age, karyotype, type of MDS, peripheral blood or bone marrow findings appeared to have no influence on the response to treatment. The median event free survival for patients who achieved CR was 15 months and the median actuarial survival 18 months. These preliminary results need to be confirmed in a multicentre prospective study comparing idarubicin with other anthracyclines.

Abstract
In a multi-centre retrospective study, we compared clinical and laboratory data in 913 patients with cryoglobulinaemias, divided as: (i) essential cryoglobulinaemias; (ii) cryoglobulinaemias secondary to connective tissue diseases (CTD), lymphoproliferative or other haematological diseases (LPD), chronic liver diseases (CLD), and 'other diseases'. Purpura was the commonest presenting feature in all groups and was more common in essential cryoglobulinaemias (p < 0.0001). Meltzer's triad (purpura, arthralgia, weakness) was less frequent, but similarly distributed. Renal involvement was randomly distributed. Neurological impairment was less frequent in cryoglobulinaemias secondary to CLD (p < 0.002). Raynaud's phenomenon, arthritis and sicca syndrome were more frequent in cryoglobulinaemias secondary to CTD. Essential cryoglobulinaemias had a significantly higher percentage of serum complement C4 < 8 mg/dl (p < 0.004), of detectable rheumatoid factor activity (p < 0.0002), and of type II cryoglobulins (p < 0.0001). Liver involvement was evident at presentation in 32.6% of essential cryoglobulinaemias, 27.1% of cryoglobulinaemias secondary to LPD and 12.2% of cryoglobulinaemias secondary to CTD. Antibodies to hepatitis B surface (HBsAg) and core (HBc) antigens were more frequent in cryoglobulinaemias secondary to CLD; anti-HBs antibodies were randomly distributed. Antibodies to hepatitis C (HCV) were tested for in 224 patients, and prevalence was high in all the groups, but lower in cryoglobulinaemias secondary to CTD (p < 0.0001). Type II and type III essential cryoglobulinaemias differed significantly in renal involvement (p < 0.0001), cryocrit > 3% (p < 0.0001), C4 < 15 mg/dl (p < 0.001), HBsAg prevalence (p < 0.01) and purpura (p < 0.05). Despite the high prevalence of HCV markers in all groups, the role of HCV in essential cryoglobulinaemia is not well defined; HBV seems to play only a marginal role.

Abstract
This study aimed to evaluate the efficacy of amikacine and ceftazidime as an empirical antibiotic therapy for neutropenic patients affected by haematological neoplasms and to investigate the presence of prognostic features suggesting a poor outcome with this antibiotic combination at the onset of infection. This could allow the identification of subgroups of patients with a low rate of response to amikacin/ceftazidime therapy; in these patients different initial empirical therapy may be indicated. The study population comprised 166 severely neutropenic (absolute neutrophil count below 500/microliters) oncohaematological patients with fever or clinical signs of infection. Multivariate analysis confirmed four negative prognostic factors: 3 or more days of hospitalization at the onset of an infectious episode, a diagnosis of acute myelmany factors are present, cases can be stratified into three groups, of significantly different prognosis: favourable (0 or 1 factor) 76% success; intermediate (2 factors) 52% success; unfavourable (3 or 4 factors) 19% success. At the onset of an infectious episode a subgroup of patients with a very low response rate to empirical amikacin/ceftazidime antibiotic therapy is identifiable, for whom a different therapy is indicated. Because of the high rate of proven or probable fungal infections in this group, the immediate administration of a systemic antifungal therapy, in addition to antibacterial agents, could be considered in these high-risk patients. Studies should be specifically addressed to evaluating a stratification of empirical antibiotic therapy according to risk factors present at the onset of infection.

Abstract
A small subgroup of human CD3-positive T-cell lymphoblastic lymphoma (T-LL) has been recently identified to express the T-cell receptor (TCR) gamma/delta heterodimer. Moreover peculiar clinical and histologic patterns of spleen and liver involvement have been associated with the TCR gamma/delta phenotype of tumor cells. In this paper we describe a human T-LL cell line (LL-DP) established in beige-nude-xid (BNX) mice, that by immunophenotype, molecular, and karyotype analyses, maintained most of the features of the patient. After serial transplants in BNX mice, LL-DP acquired quite a stable phenotype, producing a visible tumor in about 5 weeks in all the intravenously injected animals. The minimum number of transplanted cells that produce a tumor in all mice is 1 x 10(6). BNX mice bearing LL-DP lymphoma cells presented marked abdominal distension and splenomegaly. Diffuse lymphadenopathy with large tumor deposits in various lymph nodes that produce architectural effacement with a diffuse growth pattern was documented. The bone marrow was completely replaced, and spleen, liver, and kidneys were involved. Invasion of the central nervous system was leptomeningeal and perivascular. Overall this model might be useful for understanding mechanisms supporting lymphoma growth and progression as well as for testing new therapeutic strategies.

Abstract
Peripheral neuropathy often occurs in cryoglobulinemia but the pathogenesis of the peripheral nerve involvement is not completely understood, so that the relation between the reported endoneural changes and neuropathy is not clear. In this study we compared the sural nerve biopsies of 6 cryoglobulinemic patients with or without signs of peripheral neuropathy and all affected by the essential mixed type II form (ECII) and, moreover, of 8 age-matched controls. We found that in all the patients with neuropathy, axonopathy occurred and it was invariably associated with endoneural vessel damage. Moreover, the fiber losses were patchily distributed within the nerve fascicles. On the contrary both nerve fibers and vessels were normal in the patients without clinical and neurophysiological evidence of neuropathy and in controls. Our results support the hypothesis that the endoneural damage observed during ECII is not simply coincidental, but is relevant in the pathogenesis of cryoglobulinemic neuropathy. They also favor the assumption that ischemic damage of the nerve fibers occurs during ECII.

Abstract
We analysed the course and clinical features of a series of refractory anaemias (RA, RAEB, RAEBt). We could not find evidence to support the hypothesis that these three MDS classes are inevitably subsequent events of a single disease. Therefore aggressive treatment of RA, aimed at avoiding its evolution to RAEB or RAEBt, does not seem justified.

Abstract
The initial features and prognosis of non-Hodgkin's lymphoma (NHL) of the elderly have been variously evaluated in literature. We have examined 190 patients with NHL: most of them received induction therapies containing vincristine, cyclophosphamide and/or anthracyclines (CVP, CHOP, CEOP); age at diagnosis was over 65 for 62 of them (32.63%). Elderly patients had a lower rate of complete remissions, a shorter duration of complete remissions and, consequently, a poorer overall survival. In our patients, prognosis was related also with stage, histology (according to Working Formulation, WF) and performance status at the diagnosis. Elderly patient had not a significantly increased incidence of these unfavourable prognostic factors at the onset. However, patients aged 65 or more received lower doses of drugs during induction therapy (cyclophosphamide: 81%; vincristine: 73%; anthracyclines: 22% of patients under 55). Patients aged 55-65 had induction therapies of intermediate intensity; also proportion of complete remissions and survival were intermediate between the two other groups. Haematological toxicity appeared the most important cause of these reductions: in fact nadirs of neutrophils and platelets during induction therapy were similar in the 3 groups in spite of the different intensity of treatment. Even if statistical correlations are not possible, the incidence of infections has been higher in the elderly.

Abstract
Ten patients with essential cryoglobulinaemia type II were examined for peripheral nerve damage. In six cases distal symmetrical nerve involvement was present, while in three other cases abnormalities restricted to single nerves were found. Electrophysiological and morphological data were consistent with axonal damage, the larger myelinated fibres being most affected. Although active signs of vasculitis and immunoperoxidase staining for immunoglobulins were not present, endoneurial vessels were widely damaged, with abnormally thick endothelial cells and redundant basal membranes. These findings, together with a patchy distribution of myelinated fibre loss, suggest ischaemia as a cause of peripheral neuropathy during essential cryoglobulinaemia type II. A follow up examination, performed one year after haematologial remission, revealed that no further peripheral nerve damage had occurred.

Abstract
We have retrospectively examined 35 cases of non-Hodgkin's lymphoma (NHL) with gastric involvement at the onset. All patients have completed induction therapy at the time of this report. Histologic specimens have been classified according to the Working Formulation. Patients have undergone surgery and/or chemotherapy. Twenty out of 22 patients with stage I or II disease had surgery. Seventeen out of 20 gastrectomized patients achieved complete remission (11 with stage I and 6 with stage II): Fifteen of these are in their first complete remission with median follow-up of 24 months (range 8-68). Three patients with stage IV had surgery, two of which achieved CR. These data confirm that combined therapy is useful in gastric NHL presenting with stage I and II; no conclusions can be drawn regarding disseminated disease.

Abstract
In a case series of 56 patients with essential cryoglobulinemia, 35 were followed-up for 4-13 years (mean 7 years). A membranous proliferative glomerulonephritis, which in about half the cases showed a progression to renal insufficiency, was the commonest complication, observed in more than one third of the patients. In 2 patients hepatic cirrhosis became manifest after a completely asymptomatic period and in 2 others a lymphoproliferative disease appeared 2 and 8 years after the onset of purpura. In 51% of patients the intial clinical pattern did not change. In searching for a correlation between the development of nephropathy and cryoglobulin characteristics, none was demonstrated studying the cryoglobulin level, the presence of autoantibody and the complement components.
