[Heparin-induced thrombopenia: significance and difficulties of precise identification of the immunologic mechanism].
Heparin-induced thrombocytopenia (HIT) is a drug induced immunohematologic adverse reaction which is a rare but potentially very severe accident. Its diagnosis is important for epidemiologic and drug surveillance studies and in order to decide the most appropriate treatment. Its importance is enhanced since there is no gold standard diagnostic criteria. In clinical practice the diagnosis is based on a group of criteria related to clinical events and laboratory tests. We have established a score based on anamnestic criteria which allowed us to evaluate and compare two different laboratory tests: a platelet aggregation test (PAT) and a test for the detection of heparin dependent antibodies (Heparin Platelet Induced Antibodies or HPIA). The functional test PAT which is commonly used in expert laboratories detects antibodies inducing platelet aggregation in the presence of heparin. The HPIA test more recently developed is an ELISA test which detects antibodies directed at heparin-platelet factor 4 complexes. The relative value of theses two methods for the diagnosis of HIT is not well documented. We have analysed the results of these two tests in 273 consecutive patients with a suspicion of HIT. The results were concordant in 70% of patients. In selecting the patients with the lowest and the highest probability of HIT according to the score, PAT was found a more sensitive and HPIA a more specific test than the other. At low probability PAT is more often positive than HPIA 18% and 9% respectively. No test is 100% reliable, the specificity being limited for both tests since in about 20% of cases one or both tests are negative contrasting with a highly probable HIT. In this last group of patients, PAT was more frequently positive (86%) than HPIA (72%). Both tests are negative in 6% of patients suggesting the existence of presently unknown antigenic targets. Considering a group of 19 patients with a high probability of HIT, we have found antibodies against IL-8 or NAP-2 in only 7 patients. The discrepancy between a HPIA positive and a PAT negative encountered in 8% of patients may be explained by the existence of IgA or IgM immunoglobulins since in contrast to IgG they are unable to promote platelet aggregation via the CD32 platelet membrane receptor. This work suggests than neither test is 100% reliable and that they play a complementary role in the diagnosis of HIT. The potential advantage of using both tests should be confirmed in complementary studies

[Unexpected thrombocytopenia in newborn infants].
Severe thrombopenia of the newborn involves appreciable morbidity and mortality. Effective treatment exists for all forms of neonatal thrombopenia. Swiftest possible correction of thrombopenia must be the prime aim of all measures. Delaying of effective treatment due to workup must be avoided. If there is suspicion of nAIT, effective results have been achieved with transfusion of irradiated and washed maternal thrombocytes, and with immunoglobulin therapy in the case of suspected thrombopenia due to maternal autoantibodies (ITP or SLE). Transfusion of unselected thrombocytes is the therapy of choice in non-immune thrombopenia, and in immune thrombopenias it serves as an emergency measure if there is a high bleeding risk.

A new prognostic classification of chronic lymphocytic leukemia derived from a multivariate survival analysis.
Survivals of two series of CLL patients (99 from a retrospective series and 196 from a prospective series) were studied separately. The three main staging systems (Rai, Binet, Rundles) agreed well, but as far as survival is concerned, too many stages are defined. The authors performed a Cox multivariate analysis of survival in order to isolate important prognostic factors at diagnosis and to use them to build a simple three-stage classification. Thrombopenia and anemia appeared as the most important risk factors. Among the nonanemic and nonthrombopenic patients, the number of involved areas was clearly related to prognosis in the authors' two series. This study allowed the authors to propose a new classification in three prognostic groups. Group C: anemia (Hb less than 10 g) and/or thrombopenia (platelets less than 100,000/mm3); about 15% of the patients; median of 2 years. Group B: no anemia, no thrombopenia, three or more involved areas (counting as one each of the following: axillary, cervical, inguinal, lymph nodes, whether unilateral or bilateral, spleen and liver); about 30% of patients; median of 7 years. Group A: no anemia, no thrombopenia, less than three involved areas; about 55% of patients; the survival of this group does not seem different from that of the French population of the same age and sex distribution. This three-stage classification only requires clinical examination and routine hemogram, has a good prognostic value which was confirmed on the series of Montserrat and Rozman (146 patients), and should therefore be helpful in planning new clinical trials.

Toxicology and pharmacokinetics of DTGM, a fusion toxin consisting of a truncated diphtheria toxin (DT388) linked to human granulocyte-macrophage colony-stimulating factor, in cynomolgus monkeys.
We developed a fusion toxin consisting of the catalytic and translocation domains of diphtheria toxin linked to human granulocyte-macrophage colony-stimulating factor (GM-CSF) (DTGM) for the treatment of patients with acute myeloid leukemia (AML). Our goal in this study was to determine the toxicity and pharmacokinetics of DTGM in cynomolgus monkeys (Macacca fascicularis), which possess cross-reactive GM-CSF receptors. Four groups of young adult monkeys (6 males and 12 females) were treated with five daily bolus iv infusions of 1, 5, 7.5, and 10 microgram/kg DTGM. Monkeys (2 males and 2 females) treated at 1 microgram/kg/day showed no significant side effects. Monkeys (2 males and 2 females) treated at 5 microgram/kg/day showed Grade 1-2 thrombopenia (NCI common toxicity criteria) on day 9. In contrast, monkeys (6 females) treated at 7.5 microgram/kg/day developed Grade 3 neutropenia, Grade 1-2 thrombopenia, Grade 1-3 anemia, and Grade 1-3 hypoalbuminemia. The neutropenia developed by day 4 in the 7.5 microgram/kg/day monkeys and by day 3 or 5 in the 10 microgram/kg/day monkeys and resolved in both groups by day 9, but the thrombopenia, anemia, and hypoalbuminemia persisted until day 16. Monkeys (2 male and 2 female) treated with 10 microgram/kg/day showed Grade 4 neutropenia that resolved by day 8 and Grade 2-3 anemia, hypoalbuminemia, and thrombopenia. Three of the animals developed sepsis. DTGM plasma half-life was 30 min with a peak concentration of 0.1 microgram/mL or 2 nM (1000-fold higher than the IC50 in vitro for AML blasts). Immune responses were minimal in all animals tested at 14 and 28 days with anti-DTGM levels <1 microgram/mL. All four animals at 10 microgram/kg died or were euthanized, and necropsies were performed. Animals necropsied on days 4 and 6 showed marked apoptosis and hypoplasia in the marrow, which was completely resolved for animals necropsied on day 9. No injury to other organs, including kidney, heart, liver, central nervous system, or lung, was seen. The drug was selectively toxic to malignant or differentiated myeloid cells with little toxicity to myeloid progenitors or other organs. Minimal effects in nontarget tissues make DTGM a promising candidate chemotherapeutic agent.

Dose escalation study with rhenium-188 hydroxyethylidene diphosphonate in prostate cancer patients with osseous metastases.
The aim of this study was to determine the maximum tolerated dose of rhenium-188 hydroxyethylidene diphosphonate (HEDP) in prostate cancer patients with osseous metastases who are suffering from bone pain. Twenty-two patients received a single injection of escalating doses of carrier-added 188Re-HEDP [1.3 GBq (35 mCi), 2.6 GBq (70 mCi), 3.3 GBq (90 mCi) and 4.4 GBq (120 mCi)]. Blood counts and biochemical parameters were measured weekly over a period of 8 weeks. Haematological toxicity (WHO grading) of grade 3 or 4 was considered unacceptable. Clinical follow-up studies including methods of pain documentation (medication, pain diary) were performed for 6 months after treatment. In the 1.3-GBq group, no haematological toxicity was observed. First haematotoxic results were noted in those patients with a dose of 2.6 GBq 188Re-HEDP. In the 3.3-GBq group, one patient showed a reversible thrombopenia of grade 1, one a reversible thrombopenia of grade 2 and three a reversible leukopenia of grade 1. In the 4.4-GBq group, thrombopenia of grades 3 and 4 was observed in one and two patients (baseline thrombocyte count <200x10(9)/l), respectively, and leukopenia of grade 3 was documented in one patient. The overall nadir of thrombopenia was at week 4. The individual, maximum percentage decrease in thrombocytes in the 1.3-, 2.6-, 3.3- and 4.4-GBq groups was 17%, 40%, 60% and 86%, respectively. In two patients, a transient increase in serum creatinine was observed (max. 1.6 mg/dl). Pain palliation was reported by 64% of patients, with a mean duration of 7.5 weeks. The response rate seemed to increase with higher doses, reaching 75% in the 4.4-GBq group. It is concluded that in prostate cancer patients, the maximum tolerated dose of 188Re-HEDP is 3.3 GBq if the baseline thrombocyte count is below 200x10(9)/l. In patients with thrombocyte counts significantly above 200x10(9)/l, a dose of 4.4 GBq might be tolerable. Thrombo- and leukopenia are the most important side-effects. Pain palliation can be achieved in 60%-75% of patients receiving a dose of 2.6 GBq or more of 188Re-HEDP. Studies in a larger patient population are warranted to evaluate further the palliative effect of 188Re-HEDP.

Adenosplenomegaly and prognosis in uncomplicated and complicated chronic lymphocytic leukemia. A study of 362 cases.
Presence and size of lymph nodes and spleen, graded from 0 to , in 362 patients with CLL observed from diagnosis were evaluated. Statistical analysis showed a relationship with age, sex, anemia and thrombopenia, leukocytosis, and outlined two different groups: the one without organomegalies , with higher mean age (67 years), female prevalence, and better prognosis; the other with adenosplenomegaly graded ++/ , with lower mean age (57 years), clear male prevalence, and worse prognosis. Survival results were statistically different only between groups 0/+ versus group ++/ . Important chronic diseases were present at diagnosis in approximately 25% of the cases, with a severely reduced survival (median, 27 months), close to that of the cases with anemia and/or thrombopenia (22 months). Therefore it seems that in every prognostic grouping system, complicated cases should be taken into account and grouped with the anemic and/or the thrombopenic ones. The following prognostic groups are proposed: I: low risk: cases without or with adenomegaly and/or splenomegaly + (65% surviving at 100 months); II: intermediate risk: cases with adenomegaly and/or splenomegaly ++/ (median survival, 70 months); III: high risk: cases complicated by chronic diseases, or with anemia and/or thrombopenia (median survival, 25 months).

The limits of chemotherapy dose intensification using granulocyte colony stimulating factor alone in extensive small cell lung cancer.
Human Recombinant Granulocyte Colony Stimulating Factor (G-CSF) allows rapid neutrophil recovery after chemotherapy-induced leukopenia. In a prospective series of 54 patients with extensive small cell lung cancer, we evaluated the feasibility and efficacy of accelerated delivery of the AVI chemotherapy regimen. Treatment consisted of Doxorubicin 50 mg/m2 day 1, Etoposide 120 mg/m2 day 1-3 and Ifosfamide 2 g/m2 (+ Mesna 4 g) day 1 and 2 given every 2 weeks and followed by G-CSF (Neupogen, Amgen Roche 5 micrograms/kg/day s.c. day 4-14). Twenty-seven (50%) patients could not receive the total of six courses, seven because of severe septic complication, 10 because of Grade 4 thrombopenia, seven because of non-response and three because of patient refusal. Chemotherapy had to be delayed in 58 out of the 244 administered courses and this was due to thrombopenia in 48% of cases. The probability of optimal dose-on-time administration was 64% at three courses. The mean actually received dose intensity was 93% at six courses (27 patients treated). It was increased by 76% compared to our previously published conventional 3-week interval chemotherapy. The median neutrophil nadirs were stable during the successive treatment courses while haemoglobin and platelet values significantly worsened from cycle 1 to cycle 6. The overall response rate after three courses was 77% in the 48 evaluable patients. The median survival is 8 months overall and 5 months disease free. The actuarial survival is 22% at 2 years. We conclude that substantial dose intensification with accelerated chemotherapy and G-CSF support is feasible. However, the rate of severe infectious episodes is too high and thrombopenia is the main limiting factor. Either growth factors active on the megacaryocytic lineage or haematological rescue with peripheral blood stem cells might be useful in this setting.

[Haematological complications of prostatic cancer: 2 cases, one revealing the neoplasia].
INTRODUCTION: We report two cases of patients with prostate cancer who underwent haematological complications from the disease. CLINICAL CASES: Diffuse intravascular coagulopathy (with thrombopenia) was observed in two patients (55 and 59 years-old) diagnosed with prostate cancer. In one patient who had normal prostate at clinical examination, thrombopenia with incomplete diffuse intravascular coagulopathy and biological inflammatory led to diagnosis. It was initially controlled by hormonal therapy and secondary by chemotherapy. In the other patient diffuse intravascular coagulopathy followed introduction of hormonal therapy and lead to the patient's death. DISCUSSION: Patients with metastatic hormone-refractory prostate carcinoma may have life-threatening coagulation complications due to their disease. Diffuse intravascular coagulopathy is the most frequent coagulation complication. Other coagulopathies associated with prostate cancer are thrombocytopenic thrombotic purpura, thrombosis, Trousseau's syndrome and acquired factor VIII inhibitor development. Usually these haematological manifestations complicate the course of the disease and appear to have a bad prognosis. But thrombopenia or haematologic features may lead to the diagnosis of medullary metastatic prostatic cancer, even if the prostate appears normal at the initial clinical examination.

Nitroso-urea-cisplatin-based chemotherapy associated with valproate: increase of haematologic toxicity.
BACKGROUND: The incidence of haematologic toxicity of valproate (VPA) ranges from 1% to 32% and consists mainly of asymptomatic, dose-dependent thrombopenia. We describe a potentiation of haematologic side-effects of nitroso-urea (NU) when prescribed in association with VPA. PATIENTS AND METHODS: We followed a cohort of 70 patients (58 men, 22 women, mean age: 56 years, range 20-75 years). Patients with high-grade gliomas were treated with up-front chemotherapy regimen consisting of fotemustine (d3: 100 mg/m2), cisplatin (d1-3: 33 mg/m2) and etoposide (d1-3: 75 mg/m2) followed by whole brain radiotherapy at progression. Sixty patients required anti-epileptic drugs (AED) for either a single, well-documented epileptic seizure, or immediatly initiated after neurosurgical procedures. AED included VPA (35 of 60), phenobarbital (PB) (17 of 60), carbamazepine (CBZ) (2 of 60) and phenytoin (PHT) (3 of 60). Two patients had both PB and CBZ and one PB and PHT. RESULTS: Haematologic toxicity (grade 3-4 thrombopenia, neutropenia or both) was observed in 37 of 70 (52.85%) patients. Among them 24 (65%) had VPA. Group C were patients treated with fotemustine alone with or without VPA (23 patients). CONCLUSION: When prescribed in association with a fotemustine-cisplatin regimen, VPA treatment results in a three-fold higher incidence of reversible thrombopenia, neutropenia or both. Haematologic side-effects decrease after AED modification during the continued chemotherapy. This adverse event should be managed with caution.

[Neonatal alloimmune thrombocytopenia following immunization against the platelet antigen ZWA (PLA/1). 3 case reports in the same family and analysis of the literature].
Allo-immune neonatal thrombopenia is to platelets what rhesus hemolytic disease is to red blood cells. There is a risk of haemorrhage when fetal platelets decreases below 50,000 per mm3. Such haemorrhage may occur at any time during the thrombopenia period. However they are mostly due to obstetrical traumatisms during delivery. Lethal complications and severe neurologic sequellae is estimated to affect about 30% of newborns: 1/3 these complications occur in utero and 2/3 during delivery. The authors have studied 3 familial cases of foeto-maternal allo-immunisation occurring with the PLA 1 system. They have made a briefing of the physiological, the pathological and the epidemiological aspects of such immunisation before insisting upon case findings of such affected fetus. A capillary blood sample taken from the scalp of the fetus at the beginning of labour allows a safe natural delivery if fetal blood count shows more than 50,000 platelets per mm3. A fetal blood sampling under ultrasonographic guidance will bring about to an early diagnosis and prognosis, this allowing an adequate treatment for fetus with a high risk of thrombopenia.

[Treatment of autoimmune neonatal thrombocytopenia with high-dose intravenous immunoglobulins].
During the neonatal period, 6 infants born to mothers with auto-immune thrombocytopenia purpura were diagnosed as having severe thrombopenia (platelet counts below 30 X 10(9)/l). High doses of intravenous immunoglobulins (IVIG) (0.4 g/kg/injection for 2 infants and 1 g/kg/injection for 4 infants) were administered as of the first week of life. Short-term efficacy was good in all cases (platelet counts over 50 X 10(9)/l, 2-10 days after the first injection). During the second week of life, 5 newborns had relapses which were rapidly reversed by one or several IVIG injections. The thrombopenia was cured between days 19 (shortest) and 41 (longest) and, more over, no side effects were observed. High doses of IVIG seem to be an effective and well-tolerated treatment for neonatal auto-immune thrombopenia, and they can be recommended over classical treatments (corticotherapy, exchange transfusion, platelet transfusion) as a first line of attack.

Thalidomide therapy for myelofibrosis with myeloid metaplasia.
BACKGROUND: Thalidomide is a putative antiangiogenesis agent with activity in several hematologic malignancies. METHODS: Forty-four patients who had myelofibrosis with myeloid metaplasia received treatment with thalidomide in a Phase II clinical trial at a dose of 200 mg daily with escalation by 200 mg weekly until the best tolerated dose (maximum, 800 mg) was reached. RESULTS: Seventeen of 41 evaluable patients (41%) who received treatment for at least 15 days had a response. A complete response (without reversal of bone marrow fibrosis) was achieved in 4 patients (10%), a partial response was achieved in 4 patients (10%), and hematologic improvements in anemia, thrombopenia, and/or splenomegaly were observed in 9 patients (21%). Improvements in anemia occurred in 7 of 35 patients (20%) with hemoglobin levels <10.0 g/dL, and improvements in thrombopenia occurred in 5 of 24 patients (21%) with platelet counts <100 x 10(9)/L. Five of 24 patients (21%) became transfusion-independent. Major or minor regression of splenomegaly was noted in 9 of 29 evaluable patients (31%), and complete regression was noted in 5 patients. Responders had a lower baseline median vascular endothelial growth factor levels (77.9 pg/mL vs. 97.7 pg/mL; P <.01) and higher median basis fibroblast growth factor levels (60.8 pg/mL vs. 37.4 pg/mL; P <.01) compared with nonresponders. Nine patients (22%) had deterioration that was attributed to thalidomide (resolved after withdrawal) with either progressive cytopenias or excessive proliferation. Two patients developed Grade 3 neutropenia with recovery and resumed therapy with dose reductions, and both later achieved a complete response. Dose-related toxicities included fatigue (50%), constipation (48%), rash or pruritus (37%), sedation (35%), peripheral edema (29%), tremors (23%), peripheral neuropathy (22%), and orthostasis (16%). CONCLUSIONS: Thalidomide warrants further evaluation in patients with MMM, particularly in combination regimens, along with the investigation of newer analogs.

Bone marrow histopathologic patterns and immunologic phenotype in B-cell chronic lymphocytic leukaemia.
The present work analyzes the clinicobiological and immunological characteristics - the latter hitherto unexplored - of the different bone marrow histopathological patterns of the B-cell chronic lymphocytic leukaemia (B-CLL). In addition, we studied whether any or some of these parameters were able to predict the probability of a particular pattern of bone marrow involvement appearing. Of the 100 B-CLL cases studied 41 had a diffuse pattern and 59 were non-diffuse - interstitial 27, nodular 11 and mixed 21 -. Neither clinical nor immunological differences were observed among the distinct non-diffuse patterns. The patients in the diffuse group displayed an increased incidence of mu+ isotype and a higher proportion of HLA-DR and HAN-PC 1 positive cells while, conversely, reactivity with the FMC 8 McAb was lower. In addition, patients with a diffuse pattern of BM involvement displayed features of a more extensive disease: a higher incidence of adenopathies (p less than 0.05), hepatomegaly (p less than 0.01), splenomegaly (p less than 0.01), anaemia (p less than 0.01) and thrombopenia (p less than 0.01) as well as higher levels of peripheral blood lymphocytosis (p less than 0.05) and a higher percentage of BM lymphocytic infiltration (p less than 0.001). Multiple regression analysis showed that thrombopenia and splenomegaly were the two most important features in predicting the probability of a diffuse pattern.

Methylprednisolone prophylaxis protects against endotoxin-induced death in rabbits.
Endotoxemia in patients can lead to sepsis and shock by activation of cellular and plasmatic systems. Corticosteroids are described to have a beneficial effect on these phenomena. In this study of controlled endotoxic shock, we investigated the protective effects of prophylactic corticosteroid treatment against activation of cellular and plasmatic systems. In this respect, a low-dose methylprednisolone (1 mg/kg body wt) treatment was compared with that of a high-dose methylprednisolone (40 mg/kg body wt) treatment. Endotoxin infusion induced death of all rabbits, which was associated with leukopenia, thrombopenia, increased levels of beta-glucuronidase, and leukotriene B4 (LTB4) and decreased levels of complement total hemolytic activity (CH50) and tissue plasminogen activator (t-PA) activity. Both methylprednisolone regimens prevented death of the rabbits after endotoxin infusion, which correlated with a significant decrease of the granulocyte release product beta-glucuronidase (P less than 0.01). The early leukopenia and thrombopenia were not prevented; however, both cell numbers returned more rapidly to baseline values than in the placebo group (P less than 0.01, P less than 0.05). The LTB4 and CH50 concentration and t-PA activity did not differ significantly between the treated and placebo groups. These results indicate that although methylprednisolone has no inhibitory effect on the activation of the complement, arachidonic acid, and fibrinolytic systems, it protected the animals from the deleterious effects of endotoxin shock by inhibition of leukocyte activation. In this regard a low dosage of methylprednisolone is equally effective as the most often recommended high dose.

[Bone marrow diagnostic in hairy cell leukaemia (author's transl)].
Evaluation of the histologic changes of the bone marrow and clinical data of twelve male and two female patients with hairy cell leukamia before treatment. Mean age of the patients was 46 years, time from the onset of symptoms 5.5 months. 13 of the patients were anaemic, showing splenomegaly, 12 suffered from thrombopenia, 9 from granulocytopenia, and 8 from hepatomegaly. In all of the cases, the relative numbers of lymphocytes in the blood had been increased together with various amounts of characteristic hairy cells. All of the cases had a typical histologic picture of lymphocytic bone marrow infiltration, mostly of the diffuse type. In 50% of the cases not only the well known rod-like intracellular inclusions could be seen, but also ring-shaped figures whose significance is discussed. Decrease of the granulopoiesis, disintergration of the marrow sinusoids, and osteoporosis are the most important additional signs. The progression of the disease is marked by increasing bone marrow infiltration, by splenohepatomegaly, anaemia, thrombopenia, and increasing numbers of typical lymphocytes in the blood. The bone marrow being considered to be the origin of the disease for good reasons, the histobiopsy of this organ ranks among the diagnostic and prognostic measures to be taken at first sight.

Concomitant radiochemotherapy with 5-FU and cisplatin for invasive bladder cancer. Acute toxicity and first results.
PURPOSE: To evaluate acute toxicity and efficacy of simultaneous radiochemotherapy for invasive urothelial cancer of the bladder. PATIENTS AND METHODS: From September 1993 to July 1997, 61 patients with invasive bladder cancer were treated with a transurethral resection (TURB) followed by radiochemotherapy (RCT). Twenty-five received a combination of 5-FU and cisplatin. The prescribed doses were 600 mg/m2 5-FU daily as continuous infusion over 5 days each in the 1st and 5th treatment week and 20 mg/m2 cisplatin daily at the same days as a short infusion. The pelvis was irradiated with 54 Gy, the bladder with 59.4 Gy and the paraaortic nodes in 7 cases with 45 Gy, respectively. Six to 8 weeks after RCT a second TURB was performed for reasons of restaging. RESULTS: Twenty out of 25 patients received at least 80% of the prescribed chemotherapy, in 13 cases the full dose could be given. Gastrointestinal toxicity of Grade I and II occurred in 10 cases, 1 patient developed severe diarrhea (Grade VI). After the 1st course of chemotherapy 7 patients had leuko- or thrombopenia of Grade III. One patient had a leucopenia of Grade IV. After the 2nd course 4 patients developed Grade III leuko- and thrombopenia, 1 of Grade IV. Two Grade II anemia were found. All more severe toxicities and necessary dose reductions were related to radiation of the paraaortic nodes. No life threatening infections, bleedings or cardiotoxicity was found. Restaging TURBs resulted in 22 complete remissions, 1 patient had a de-novo-carcinoma (Tis) at this time, 2 were non-responders (8%). After a median follow-up of 38 months 20 patients are alive (80%). CONCLUSIONS: 1. If irradiation of paraaortic nodes is necessary, 5-FU should not be applied, because the gastrointestinal toxicity is too extensive. In all other cases side effects are tolerable and can be managed by supportive care. 2. The first results are promising and should be evaluated in a prospective study.
