Heterogeneity of t(4;14) in multiple myeloma. Long-term follow-up of 100 cases treated with tandem transplantation in IFM99 trials.

One hundred de novo multiple myeloma patients with t(4;14) treated with double intensive therapy according to IFM99 protocols were retrospectively analyzed. The median overall survival (OS) and event-free survival (EFS) were 41.4 and 21 months, respectively, as compared to 65 and 37 for patients included in the IFM99 trials without t(4;14) (P<10(-7)). We identified a subgroup of patients presenting at diagnosis with both low beta(2)-microglobulin <4 mg/l and high hemoglobin (Hb) >/=10 g/l (46% of the cases) with a median OS of 54.6 months and a median EFS of 26 months, respectively, which benefits from high-dose therapy (HDT); conversely patients with one or both adverse prognostic factor (high beta(2)-microglobulin and/or low Hb) had a poor outcome. The achievement of either complete response or very good partial response after HDT was also a powerful independent prognostic factor for both OS and EFS.

Host and bacterial determinants of initial severity and outcome of Escherichia coli sepsis.

A 1-year prospective cohort study of all episodes of Escherichia coli bacteraemia in two French university hospitals was conducted to assess simultaneously the influence of host and bacterial determinants on the initial severity and outcome of E. coli sepsis. Clinical data (community-acquired/nosocomial infection, immune status, underlying disease, primary source of infection, severity sepsis scoring and outcome), phylogenetic groups (A, B1, D and B2), nine virulence factors (VFs) (papC, papGII, papGIII, sfa/foc, hlyC, cnf1, iucC, fyuA and iroN) and the antibiotic susceptibility of isolates were investigated. All VFs except iucC were significantly more prevalent (p <0.05) among the B2 group isolates. The non-B2 isolates were more frequently resistant to antibiotics than were B2 isolates (p <0.05). There were significantly more B2 isolates from immunocompetent than from immunocompromised patients (p <0.05). No bacterial or host determinants influenced the initial severity of sepsis. Multivariate analysis revealed that the presence of papGIII, septic shock at baseline and a non-urinary tract origin of sepsis were associated independently with a fatal outcome (p 0.04, <0.0001 and 0.04, respectively). A factorial analysis of correspondence allowed two populations of isolates to be distinguished: those belonging to the B2 group were associated more frequently with susceptibility to antibiotics, community-acquired infection, a urinary tract origin and immunocompetent hosts; those belonging to the A, B1 or D groups were associated more frequently with resistance to antibiotics, a nosocomial origin, a non-urinary tract source and immunocompromised hosts. Although no influence of host or bacterial determinants on the initial severity of sepsis was detected, bacterial and host determinants both influenced the outcome of E. coli sepsis significantly.

Double intensive consolidation chemotherapy in adult acute myeloid leukemia.

Of 115 adult patients with de novo acute myeloid leukemia (AML), 87 (75.5%) achieved complete remission (CR) after induction treatment with zorubicin and conventional doses of cytarabine (Ara-C). Patients under age 45 years with histocompatibility locus antigen-identical sibling underwent bone marrow transplantation (BMT). The others were treated with two courses of intensive consolidation chemotherapy (ICC): course 1 with 4 days of high-dose Ara-C and 3 days of amsacrine (m-AMSA); course 2 with carmustine (BCNU), Ara-C, cyclophosphamide, and etoposide. Forty-two patients received both planned courses, 15 received only the first, and 13 patients could only support conventional maintenance therapy. Four patients died during consolidation. With a median follow-up of 60 months, the disease-free survival (DFS) after ICC at 5 years is 40.3% (+/- 6.5%), with no statistically significant difference between patients receiving one or two courses. The DFS for the 17 transplanted patients is comparable (P = .72) and is lower for the 13 excluded patients (23% +/- 11.5%, P = .046). Age did not influence the probability of remaining in CR. In univariate analysis, three parameters had a negative impact on the 5-year DFS: a high initial WBC count (52% for patients with less than 30 x 10(9) WBC/L v 12% for patients with greater than 30 x 10(9) WBC/L, P = .01), a long delay between induction treatment and course 1 (+/- 60 days; 63% v 29%, P = .01), and a long delay between course 1 and course 2 (+/- 60 days, 61.5% v 28.5%, P = .05). In multivariate analysis (Cox model), only the WBC count remained significant. This study confirms the value of intensive postremission chemotherapy, which can be compared in AML with allogeneic or autologous BMT. It also demonstrates the prognostic value of the initial WBC count. The optimal modalities of ICC remain to be defined by further studies.

Low-dose cytarabine versus intensive chemotherapy in the treatment of acute nonlymphocytic leukemia in the elderly.

We conducted a randomized multicenter trial comparing low-dose cytarabine (LD ARA-C) (20 mg/m2 for 21 days) with an intensive chemotherapy (rubidazone [a daunorubicin-derived agent], 100 mg/m2 for 4 days, ARA-C 200 mg/m2 for 7 days) in 87 patients over 65 years of age with de novo acute nonlymphocytic leukemia (ANLL). Forty-one patients received LD ARA-C and 46 received intensive chemotherapy. The number of complete remissions (CRs) but also of early deaths was higher in the intensive chemotherapy group, while partial remissions (PRs) and failures were more frequent in the LD ARA-C group (P less than .001). Infectious complications during induction treatment were more numerous and more severe in the intensive chemotherapy group (P less than .01). Patients treated with LD ARA-C required fewer RBC transfusions (P less than .02), fewer platelet transfusions (P less than .01), and had a shorter hospital stay for induction treatment (P less than .01). Overall survival and CR duration were not significantly different in either group. In the LD ARA-C group, the survival of patients with PR and those of patients in CRs was identical. We conclude that in a selected group of elderly patients with de novo ANLL a higher number of CRs may be obtained with intensive chemotherapy, but that with LD ARA-C, the number of early deaths is lower, and long-lasting PRs are obtained, resulting in a similar overall survival.

Mediastinal tumor size and response to chemotherapy are the only prognostic factors in supradiaphragmatic Hodgkin's disease treated by ABVD plus radiotherapy: ten-year results of the Paris-Ouest-France 81/12 trial, including 262 patients.

PURPOSE: To identify prognostic factors in 262 patients with supradiaphragmatic Hodgkin's disease (HD), clinical stages (CS) I and II, prospectively treated between 1981 and 1988 according to the Paris-Ouest-France (POF) 81/12 protocol by three 1-month cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine plus methylprednisone (ABVD-MP) followed by subtotal nodal irradiation (RT). PATIENTS AND METHODS: The size of mediastinal tumor (MT) was measured in all patients: 66 did not have MT (NoMT); 105 had a small-size MT (SSMT), ie, mediastinal mass ratio (MMR) less than 0.33; 58 had a medium-size MT (MSMT), ie, MMR > or = 0.33 and less than 0.45; and 33 had a bulky MT (BuMT), ie, MMR > or = 0.45. All patients received three cycles (CS IA, one cycle only) of ABVD-MP; patients in partial remission (PR) or complete remission (CR) after chemotherapy (CT) received supradiaphragmatic RT (involved fields, 40 Gy; adjacent fields, 30 Gy) plus lumboaortic and splenic RT (30 Gy); patients not in CR or PR after CT received salvage CT. RESULTS: Two hundred seventeen patients (82.8%) entered CR after CT and 258 (98.5%) after RT. Ten-year freedom-from-progression (FFP) and survival rateswere 88.6% and 89.4%, respectively. According to univariate analysis, MT size and post-CT status were the only factors to influence both FFP and survival. For patients with NoMT or SSMT, those with MSMT, and those with BuMT, FFP rates were 94.1%, 87.0%, and 63.0% (P < .001), respectively, while corresponding survival rates were 92.6%, 87.2%, and 78.2% (P < .05). FFP rates were significantly different between the patients who achieved CR and those who did not achieve CR after CT: 94.6% versus 65.3% (P < .001); corresponding survival rates were 89.9% and 73.7% (P < .01). Multivariate analysis confirmed that MT size and post-CT status were the only two prognostic factors for FFP; for survival, the same two characteristics, as well as age (< 40 v > or = 40 years), significantly affected prognosis. We were thus able to identify three groups. The 33 patients (12.6%) with a BuMT had 10-year FFP and survival rates of 63.0% and 78.2%, respectively. Of 229 patients without BuMT, the 195 who attained CR after CT had an optimal prognosis (FFP, 96.6%; survival, 93.6%), while those who failed to achieve CR after CT had an intermediate prognosis (FFP, 68.8%; survival, 77.6%). CONCLUSION: These results demonstrate the independent impact on HD prognosis of tumor burden and post-CT status.

Granulocyte colony-stimulating factor after intensive consolidation chemotherapy in acute myeloid leukemia: results of a randomized trial of the Groupe Ouest-Est Leucémies Aigues Myeloblastiques.

PURPOSE: Ten years after the first clinical studies, the clinical impact of myeloid growth factors in acute myeloid leukemia is still unclear. One of the objectives of the Groupe Ouest-Est Leucémies Aigues Myeloblastiques (GOELAM) 2 trial was to evaluate the benefit of granulocyte colony-stimulating factor (GCSF) given only after the two courses of intensive consolidation chemotherapy (ICC) used to maintain complete remission (CR). PATIENTS AND METHODS: One hundred ninety-four patients who were in CR after induction treatment were randomly assigned to receive G-CSF (100 patients) or no G-CSF (94 patients) after two courses of ICC (ICC 1, high-dose cytarabine plus mitoxantrone; ICC 2, amsacrine plus etoposide). G-CSF (filgrastim) was administered from the day after chemotherapy until granulocyte recovery at a daily dose of 5 microg/kg. RESULTS: In the G-CSF group, the median duration of neutropenia (< 0.5 x 10(9)/L) was dramatically reduced, both after ICC 1 (12 v 19 days, P <.001) and after ICC 2 (20 v 28 days, P <.001). The median duration of hospitalization was also significantly shorter in the G-CSF group (24 v 27 days after ICC 1, P <.001; 29 v 34 days after ICC 2, P <. 001). The median duration of intravenous antibiotics was significantly reduced after ICC 1 and ICC 2, and the median duration of antifungal therapy was significantly reduced after ICC 1. However, the incidence of microbiologically documented infections, the toxic death rate, the 2-year disease-free survival, and the 2-year overall survival were not affected by G-CSF administration. Moreover, the median interval between ICC1 and ICC2 was reduced by only 2 days, and the number of patients undergoing ICC2 was not increased in the G-CSF arm. CONCLUSION: G-CSF should be administered routinely after ICC to reduce the duration of neutropenia and hospitalization. However, G-CSF did not seem to significantly increase the feasibility of this two-course program or modify overall outcome.

Cyclosporin A as a modifier agent in the salvage treatment of acute leukemia (AL).

Sixteen adult patients with relapsed (7 patients) or refractory (9 patients) acute leukemia received mitoxantrone (10 mg/m2 per day for 3 days) and etoposide (200 mg/m2 per day for 3 days) with escalating dose of cyclosporin A (CsA) from a loading dose of 2 mg to 6.5 mg/kg per 2 h followed by 3 days continuous infusion of 5-15 mg/kg per day. The major toxicities were stomatitis and prolonged aplasia, occurring for 15 mg/kg per day of CsA. Transient conjugated hyperbilirubinemia occurred in all patients, and was CsA dose-dependent (r = 0.7). Adequate serum levels of CsA (> 1 microgram/ml) were obtained in 3/6 patients treated with 10 mg/kg per day and 4/4 patients with 15 mg/kg per day. The pharmacokinetic of mitoxantrone showed an unusual increase of carboxylic metabolites, parallel to CsA levels. We observed six responses (two complete and four partial remissions), and eight resistances. Two patients died at days 3 and 8 from sepsis. Before treatment, 7/16 patients tested for P-gp with C219 were positive (> 10% positive cells). 3/6 responders were P-gp-positive. At time of leukemic regrowth, cells expressing P-gp before therapy reverted to P-gp-negative cells.

Daunorubicin continuous infusion induces more toxicity than bolus infusion in acute lymphoblastic leukemia induction regimen: a randomized study.

We report the first randomized study assessing the efficacy and safety of daunorubicin (DNR) continuous infusion (CI) compared to the more conventional 30-min infusion (i.v.) in newly diagnosed adult acute lymphoblastic leukemia (ALL). Seventy-seven patients were initially randomized to receive either a 24-h CI DNR (60 mg/m2 days 2-4) (40 patients) or bolus DNR at the same dosage (37 patients) with vincristine (2 mg i.v. days 1, 8, 15) and oral prednisone (60 mg/m2 days 1-15), without hematopoietic growth factor support, as an induction regimen. The distribution of adverse prognostic factors was comparable in the two-induction arm. Acute toxicity was more important in the CI arm. Gram negative infection (9 vs 1 gram negative septicemia, P = 0.01) and infection-related deaths (6 vs 1 deaths, P = NS) occurred more frequently in the CI arm during the induction treatment than in the i.v. arm, leading to the study interruption. Neutropenia but not thrombopenia duration was significantly longer in the CI arm than in the i.v. arm (18 days vs 14 days, P > 0.05 and 16 days vs 12 days, P > 0.05, respectively). Despite a similar CR rate according to the method of DNR administration (68% in the CI DNR arm vs 76% in the i.v. arm after the first course), there was a trend toward higher freedom from relapse (FFR) after DNR CI (48% vs 28% in the i.v. arm at 5 years, P = NS), suggesting that despite this high toxicity, DNR CI may improve the CR quality and decrease further the residual disease.

A prospective study of autologous bone marrow or peripheral blood stem cell transplantation after intensive chemotherapy in myelodysplastic syndromes. Groupe Français des Myélodysplasies. Group Ouest-Est d'étude des Leucémies aiguës myéloïdes.

We prospectively assessed autologous stem cell transplantation for consolidation treatment in a trial of intensive chemotherapy in high risk myelodysplastic syndromes (MDS). In this trial, patients aged 55 years or less with no HLA-identical sibling and achieving CR were scheduled to receive unmanipulated autologous bone marrow transplantation (ABMT) preceded by a consolidation chemotherapy course. Forty-two of the 83 patients aged 55 years or less included in the trial (51%) achieved CR. Three were allografted in CR. Twenty-four of the remaining 39 patients who achieved CR (62%) received ABMT (16 patients) or autologous peripheral blood stem cell transplantation (APSCT) (eight patients). Indeed, as bone marrow harvest was often insufficient, APSCT was subsequently proposed after mobilization by consolidation chemotherapy followed by G-CSF. The conditioning regimen combined cyclophosphamide and busulfan. ABMT and APSCT were performed 1-7 months (median 3) after CR achievement. Hematological reconstitution occurred in all patients and tended to be faster after APSCT than ABMT although not significantly. Three patients died from the procedure, nine relapsed after 2-26 months and 12 (50%) were still in CR after 8-55 months. In autografted patients, median Kaplan-Meier disease-free survival and survival were 29 and 33 months from the autograft, respectively. Thus, ABMT or APSCT can be performed in almost two-thirds of MDS patients who achieve CR with intensive chemotherapy. PBSC collection may yield higher numbers of stem cells than marrow collection in some cases, and could improve the percentage of MDS patients autografted in CR. Longer follow-up is required to determine if autograft will prolong CR duration in at least some patients.

Protein tyrosine kinases in activation signal of human basophils through the immunoglobulin E receptor type l.

Human basophils activated through high-affinity immunoglobulin E (IgE) receptors (Fc epsilon RI) are involved in the late phase of the allergic reaction. To investigate the possible involvement of protein-tyrosine kinases in this activation we used human acute basophilic leukemia (ABL) cells in culture as well as a pure population of normal basophils in vitro-derived from human bone marrow precursor cells (HBMB). ABL cells were 50-80% basophils at various stages of maturation as assessed by staining, morphology, ultrastructure, and flow cytometry analysis, and only basophils in ABL cells expressed Fc epsilon RI. Aggregation of Fc epsilon RI by IgE and anti-IgE, IgE and antigen, or anti-Fc epsilon RI monoclonal antibodies on ABL cells or on HBMB, led to increased tyrosine phosphorylation of 120-, 100-, 80-, 72-, 50- to 65-, and 38-kDa substrates. Tyrosine phosphorylations in ABL cells were in basophils because 1) they were detected after a 5-s stimulation, 2) they were observed under conditions where mediator release is minimal, i.e., in the absence of extracellular calcium, 3) hapten addition during antigen stimulation resulted in almost total disappearance of tyrosine phosphorylations within 30 s. There was correlation between histamine release and tyrosine phosphorylation in anti-IgE dose-responses and in dose-responses of the tyrosine kinase inhibitor genistein. The tyrosine kinase p72syk was detected in the cells. Stimulation of ABL cells for 1 min resulted in extracellular calcium-independent tyrosine phosphorylation and activation of p72syk. Therefore, tyrosine kinases are involved in the early steps of human Fc epsilon RI signaling in basophils. Tyrosine kinases and their substrates could represent new potential therapeutic targets to prevent the development of the allergic reaction.

[Strokes associated with cervical artery dissection, and systemic mastocytosis: an unfortuitous association? A report of two cases]. / Accident vasculaire cérébral sur dissection artérielle, au cours des mastocytoses systémiques: une association non fortuite? A propos de deux cas.

INTRODUCTION: Neuropsychiatric symptoms in systemic mastocytosis are usually cognitive and affective changes. EXEGESIS: We describe here two systemic mastocytosis patients without eosinophilia presenting strokes associated with cervical artery dissection. CONCLUSION: These observations are the first reported and they suggest that systemic mastocytosis could be add to the predisposing factors of spontaneous cervical artery dissections.

[Systemic mastocytosis]. / Les mastocytoses systémiques.

Systemic mastocytosis is characterized by abnormal mast cell proliferation in different organs. The 2001 consensus classification distinguishes in separate categories indolent systemic mastocytosis, systemic mastocytosis with concomitant blood disease, aggressive systemic mastocytosis and mast cell leukemia. Clinical manifestations are caused by tissue infiltration by proliferating mastocytes and by release of mediators. The principal organs affected are the skin, bones, digestive tract, liver, spleen and lymph nodes. Diagnosis of mastocytosis is based on appropriate stains (Giemsa, toluidine blue) and immunophenotype features (tryptase, CD117, also known as c-KIT and stem cell factor receptor). Serum tryptase levels reflect the total mast cell burden. Treatment must prevent release of mast cell mediators (histamine antagonists, cromolyn sodium, corticosteroids, or leukotriene-receptor inhibitors), limit bone involvement (bisphosphonates) and reduce the number of circulating mast cells (interferon, cladribine, or tyrosine kinase inhibitors). Enhanced understanding of the pathogenic mechanisms (mutation of c-kit and platelet-derived growth factor receptor alpha has led to the development of targeted treatments, including new inhibitors of tyrosine kinase and of nuclear factor Kappa B.

Hypothalamo-pituitary-adrenal function in human immunodeficiency virus-infected men.

We prospectively studied adrenal function in 51 human immunodeficiency virus-positive male patients, including heterosexuals, homosexuals, and iv drug users, classified according to 1987 CDC criteria as belonging to stages II/III or IVC. Basal serum concentrations of cortisol (F), progesterone (P4) and 17 alpha-hydroxyprogesterone (17 alpha-OHP4) were determined during the two stages. In stage IVC patients, the circadian rhythms of ACTH and F were assessed, and ovine CRH (oCRH) and immediate cosyntropin-stimulating tests were evaluated. Serum concentrations of hormones were analyzed in relationship to the absolute CD4 cell count in all subjects. The mean serum F concentration in stage IVC patients, the mean P4 concentration in stage II/III and IVC patients, and the mean 17 alpha-OHP4 level in stage II/III patients were significantly increased compared to control values (P < 0.0001, P < 0.0001, and P < 0.002, respectively). The mean serum F concentration in stage IVC patients was significantly increased compared to that in stage II/III patients (P < 0.004), and the mean serum 17 alpha-OHP4 concentration in stage II/III patients was significantly increased compared to that in stage IVC patients (P < 0.02). In the 22 stage IVC patients, the circadian rhythms of ACTH and F were normal in all but 7 for ACTH and 5 for F, whereas oCRH test results indicated that 14 of them had reduced or blunted responses. By contrast, cosyntropin stimulation results were normal. CD4 cell counts were significantly negatively correlated with the serum F concentration (P < 0.02). In conclusion, during human immunodeficiency virus infection, the serum F concentration was negatively correlated with CD4 cell counts. Cosyntropin test results were normal, but 63% of the stage IVC men had abnormal responses to oCRH.

Prognostic factors in polyarteritis nodosa and Churg-Strauss syndrome. A prospective study in 342 patients.

We undertook this study to determine the clinical, biologic, immunologic, and therapeutic factors associated with the prognoses of polyarteritis nodosa (PAN) and Churg-Strauss syndrome (CSS). Three hundred forty-two patients (260 with PAN, 82 with CSS) followed from 1980 to 1993 were included in a prospective study on prognostic factors. Two hundred eighty-eight of these patients were included in the prospective studies on PAN and CSS. Items to be considered for analysis were collected at the time of diagnosis, during the acute phase of the disease. A survival curve was plotted for each clinical and biologic symptom observed in PAN or CSS. Each treatment arm of the prospective therapeutic trials was also tested: 1) prednisone (CS) + oral cyclophosphamide (CYC) + plasma exchanges (PE) versus CS E, 2) CS + PE versus CS, 3) CS + oral CY versus CS + pulse CY, 4) CS + pulse CY + PE versus CS + pulse CY in severe PAN and CSS, and 5) PE + antiviral agents after short-term CS in hepatitis B virus-related PAN. Of the parameters thus evaluated, the following had significant prognostic value and were responsible for higher mortality: proteinuria > 1 g/d (p < 0.0001; relative risk [RR] 3.6), renal insufficiency with serum creatinine > 1.58 mg/DL (p < 0.02; RR 1.86), GI tract involvement (p < 0.008. RR 2.83 for surgery). Cardiomyopathy and CNS involvement were associated with a RR of mortality of 2.18 and 1.76, respectively; these were not statistically significant. Similar survival rates were obtained with the prospectively tested therapies. The five-factors score (FFS) we established considered the prognostic factors creatinemia, proteinuria, cardiomyopathy, GI tract involvement, and CNS signs. Multivariate analysis showed that proteinuria (due to vascular or glomerular disease) and GI tract involvement were independent prognostic factors. When FFS = 0 (none of the 5 prognostic factors present), mortality at 5 years was 11.9%; when FFS = 1 (1 of the 5 factors present), mortality was 25.9% (p < 0.005); when FFS > 2 (3 or more of the 5 factors present), mortality was 45.95% (p < 0.0001 between 0 and 2, p < 0.05 between 1 and 2). We conclude that an initial assessment of PAN or CSS severity enables outcome and mortality to be predicted. The FFS is a good predictor of death and can be used to help the clinician choose the most adequate treatment. Renal and GI signs are the most serious prognostic factors.

Streptococcus pneumoniae endocarditis in adults. A multicenter study in France in the era of penicillin resistance (1991-1998). The Pneumococcal Endocarditis Study Group.

To better define the overall characteristics and risk factors for dying of adult pneumococcal endocarditis (PE) focusing on the echocardiographic diagnosis, the impact of surgery, and emergence of penicillin resistance, the medical and microbiologic charts of adult PE cases observed between 1991 and 1998 in university and general hospitals were reviewed through a nationwide retrospective study in France. Thirty cases of PE (22 men, 8 women; median age, 53 yr; range, 27-87 yr) were collected and validated. Twenty patients (66.7%) had no known predisposing cardiopathy; 4 had a bioprosthetic valve. The primary focus of infection was pneumonia in 10 (33.3%), and meningitis was noted in 12 (40.0%). Half the patients suffered from chronic alcoholism. Echocardiography detected vegetation(s) in 29 cases (96.7%), valvular perforation in 6 (20.0%), and/or valve ring abscess in 4 (13.3%). The most frequent complications were congestive heart failure (n = 19), large arterial emboli (n = 8), and focal abscesses (n = 7). Five strains were penicillin-resistant. Twenty (66.7%) patients underwent valve replacement, 12 of them during the first month. The overall mortality rate was 24.1%. According to a multivariate analysis, the risk factors independently associated with dying were age > or = 65 yr and septic shock, while cardiac surgery was protective (p < 0.01). In conclusion, PE is usually fulminant and causes severe valve damage and embolic complications; its short-term prognosis might be improved by early valve replacement.

Churg-Strauss syndrome. Clinical study and long-term follow-up of 96 patients.

Churg-Strauss syndrome (CSS) is a systemic vasculitis characterized by the presence of asthma, hypereosinophilia, and necrotizing vasculitis with extravascular eosinophil granulomas. In this retrospective study of 96 patients between 1963 and 1995, we analyzed clinical manifestations, identified prognostic factors, and assessed the long-term outcome. CSS was diagnosed when asthma, hypereosinophilia > 1,500/mm3 or > 10%, and clinical manifestations consistent with systemic vasculitis, with or without histologic evidence, were present. Asthma was the most frequently observed manifestation at presentation, with mononeuritis multiplex the second. Other common manifestations were weight loss, fever, myalgia, skin involvement, paranasal sinusitis, arthralgia, pulmonary infiltrate, and gastrointestinal involvement. Mean eosinophilia at presentation was 7.193 +/- 6.706/mm3; ANCA, present in 20 of 42 (47.6%) patients, predominantly gave the perinuclear labeling pattern. All the patients were treated with corticosteroids alone or in combination with cyclophosphamide or plasma exchanges. Clinical remission was obtained in 91.5%; 22 (25.6%) patients relapsed. Twenty-three patients died during follow-up: 11 of these deaths were directly due to vasculitis. The presence of severe gastrointestinal tract or myocardial involvement was significantly associated with a poor clinical outcome. The long-term prognosis of CSS is good and does not differ from that of polyarteritis nodosa, although most patients need low doses of oral corticosteroids for persistent asthma, even many years after clinical recovery from vasculitis.

Front-line high-dose therapy with autologous stem cell transplantation for high risk Hodgkin's disease: comparison with combined-modality therapy.

This retrospective study compares high-dose therapy (HDT) with autologous stem cell transplantation and combined-modality treatment (CT) as a first-line therapy for Hodgkin's disease (HD) for patients with both a clinical stage (CS) IV and/or a mediastinal mass > or =0.45 of the thoracic diameter (MM > or =0.45) at diagnosis, and an incomplete response after the first-line chemotherapy. Data on 42 grafted patients (GP) in Nantes Hospital, France and on 108 combined-modality treated patients (CTP) from two protocols of the GOELAMS group, France (POF 81 and H90) was analyzed. Both groups were comparable except for pulmonary disease in excess in the grafted group (P = 0.01). Among GP, 95% were in complete response at the end of first-line treatment and 77% among CTP. Median follow-up was 53 months (range, 7 to 128 months) for GP and 88 months (range, 25 to 181 months) for CTP. The 5-year freedom from progression (FFP) and event-free survival (EFS) rates were better for GP (87% vs 55% for FFP: P = 0.0004 and 81% vs 51% for EFS: P = 0.0004) whereas the overall survival (OS) rates did not differ significantly (85% for GP vs 71% for CTP: P = 0.06). Similar results were obtained for the groups with a response > or =50% after initial chemotherapy: 91% vs 65% for FFP, P = 0.01; 87% vs 61% for EFS, P = 0.02; and 92% vs 77% for OS, P = 0.2; and for the groups with a response <50%: 80% vs 22% for FFP, P = 0.0003; 72% vs 13% for EFS, P = 0.0001; and 76% vs 46% for OS, P = 0.04. This study shows a better control of the disease with HDT.

Infradiaphragmatic Hodgkin's disease: long term results of combined modality therapy.

Hodgkin's disease (HD) confined below the diaphragm accounts for less than 5% of all patients with HD. Although the major characteristics of this presentation appear established, optimal modalities of treatment still remain difficult to define. From April 1972 to October 1988, 28 patients with newly diagnosed infra-diaphragmatic HD, clinical stages I or II have been treated with 3 successive prospective protocols combining initial chemotherapy and radiotherapy (40 gy). This series of patients accounted for 4,3% of patients with HD limited to clinical stages (CS) I and II. Overall survival and freedom from relapse at 15 years were 74,4% and 73% respectively, without significant differences between clinical stages I and II, presence or absence of B symptoms or histologic subtype. There is only a trend (p < 0,10) in favour of patients younger than 40 years. In all 7 clinically staged IA patients no relapses were seen and combined treatment does not appear to be better than inverted Y irradiation alone. On the other hand initial chemotherapy seems necessary in patients with CS II A and B since 15 of our 21 patients are alive in first CR whereas the crude rate of transdiaphragmatic nodal relapses may reach up to 53% following radiotherapy alone.

Relationship between sex steroid hormone levels and CD4 lymphocytes in HIV infected men.

The serum concentrations of the steroid, androgens and estrogens, in the HIV-positive male patients were studied. These men belonged to one of the three main behaviour groups: heterosexual (He), drug addicts (DA) and homosexual (Ho) at early stages (II and III) or at advanced stage of AIDS (IVC), classified according to the Centers for Disease Control (CDC). The circulating concentrations of sex steroids were then analysed with reference to the risk factors, absolute CD4 cell count and the progression of HIV infection. Regardless of risk factors, the stage II and III HIV-infected patients had serum dehydro-epiandrosterone sulfate (DHEAs) (+37%, p < 0.03), testosterone (T) (+24%, p < 0.006) and estrone (E1) (+170%, p < 0.0001) levels higher than those of controls. The patients IVC stage had low serum DHEAs (-48%, p < 0.0001) and elevated estradiol (E2) (+200%, p < 0.0001). According to risk factors, there were no significant differences in androgen and estrogen concentrations between the behaviour groups. There were significant positive correlations between the CD4 cell count and the serum concentrations of DHEAs (p < 0.0001), DHEA (p < 0.01) and E1 (p < 0.006). This suggests that there is a relationship between the circulating sex hormone levels, particularly DHEAs, and the progression of immune depression in HIV, whatever the risk factor. The observed association between DHEAs and the progression of HIV infection suggests that this androgen may play a role in the normal function of the immune system.

Exercise is not associated with better diabetes control in type 1 and type 2 diabetic subjects.

In the clinical setting, the impact of educational efforts on the amount of regular exercise and its effects on diabetes control are unclear. Fifty type 1 diabetic, 50 type 2 diabetic and 70 non-diabetic subjects were evaluated using a questionnaire for type, duration and intensity of exercise to assess weekly energy expenditure. Diabetic subjects did not exercise more than controls: 36% of the type 1, 46% of the type 2 and 46% of the control subjects admitted no physical activity, and those exercising regularly had similar energy expenditure: 1808 +/- 320, 2722 +/- 617, 2523 +/- 304 (mean +/- SEM) kcal/week respectively (P = NS). There was no correlation between the degree of activity and HbA1c levels, or hypoglycaemic events. HbA1c levels were less than 6,8% in 31% of nonactive patients versus 21% of active patients (P = NS). A negative correlation was found between physical activity and daily insulin usage (r = 0.27, P less than 0.05), but differences between patients averaged only 4IU/1000 kcal energy expenditure/day. We conclude that patients' attitude towards exercise was not improved by our educational methods and that physical exercise was not necessarily associated with good blood glucose control.
