Treatment of chronic hepatitis B and C with alpha interferon in a renal transplant patient.

We report the case of a 51-year-old renal transplant patient, treated by interferon alpha (5MUI, three times a week) since he presented a coinfection by hepatitis B (HBV) and hepatitis C (HCV) virus for more than 7 years, associated with a chronic increase in serum alanine aminotransferase (ALT) levels and a chronic active hepatitis. The 4-month treatment was associated with a sustained normalization of ALT, a disappearance of HBV replication and a transient clearance of HCV viremia. Side effects were moderate and included thrombopenia (90,000/mm3), leucopenia (2200/mm3), an increase in serum creatinine (178 mumol/l). The withdrawal of alpha interferon was associated with the correction of these parameters. No rejection was observed on kidney biopsy. Meanwhile, liver histology was not affected by the treatment. To date, nineteen months after the end of alpha interferon therapy HBV DNA was still negative; ALT remained normal despite the early recurrence of HCV viremia; this emphasized the fact that HBV infection was certainly the most important factor involved in the patient's chronic hepatitis. It is concluded that alpha interferon therapy is able to decline HBV replication for a prolonged period in renal transplant patient although its use should be performed with caution due to the potential renal side effects.

Prednimustine, methotrexate, 5-fluorouracil, mitoxantrone and tamoxifen for advanced breast cancer in postmenopausal women. A phase II trial.

A phase II trial in postmenopausal women with advanced breast cancer naive to cytotoxic treatment for recurrent disease was performed with a combinated chemo-endocrine regimen of prednimustine, methotrexate, mitoxantrone, 5-fluorouracil, and tamoxifen. Thus we replaced the most toxic agents--cyclophosphamide and doxorubicin often used in combinations--with prednimustine and mitoxantrone respectively, which are supposed to be equally efficient but less toxic. Seventy-seven patients were registered but 6 were ineligible. Complete response was obtained in 11%, partial response in 29%, no change in 29%, and progressive disease in 31%. Median duration of response was 18.5 months, time to disease progression 9.2 months, and survival 16.0 months. Toxicity was modest; 61% had no or only moderate alopecia not necessitating a wig, 59% had no or only moderate, if any, nausea. Bone marrow suppression, especially thrombopenia, was a major dose limiting factor. This regimen seems to be effective and have low toxicity in advanced breast cancer in postmenopausal women.

Cisplatin and ifosfamide in patients with advanced squamous cell carcinoma of the uterine cervix. A phase II trial.

Thirty patients with advanced squamous cell carcinoma of the cervix were included in a phase II study with cisplatin (DDP) and ifosfamide (IF)/mesna. They received a median of 4 courses of chemotherapy and were all evaluable for response and toxicity. Each cycle consisted of 2,500 mg/m2 IF i.v. days 1-5; mesna 500 mg/m2 i.v. at hours 0 and 2, and 1,000 mg/m2 per os at hours 6 and 10, days 1-5; DDP 20 mg/m2 i.v., days 1-5. Cycles were repeated every 4 weeks. One patient obtained CR and 14 PR giving an overall response rate of 50%. Mean duration of response was 21 months. Anemia grade 3 developed in 7 patients, leukopenia grade 3 in 9 patients and grade 4 in one patient; thrombopenia grade 3 in 2; creatinine clearance grade 3 in one; CNS grade 3 in one and cystitis grade 3 in one patient. Overall median survival time was about 25+ months (3-63+); after a follow-up of 70 months, 11 patients (37%) are still alive with a median survival of 31+ months. IF plus DDP seems to be a good combination for treatment of advanced cervical cancer, with acceptable tolerance and response rate.

Prolonged treatment with tolfenamic acid in inflammatory rheumatic diseases.

The aim of this study was in the first place to elucidate the tolerance of rheumatic patients to prolonged treatment with tolfenamic acid. 91 patients took part in the trial, most of them suffering from rheumatoid arthritis. The daily dose of tolfenamic acid was 600 mg and the trial lasted 6 months. The side-effects were usually slight: diarrhea occurred in 8, other gastrointestinal disturbances in 11, dysuria in 8 and other side-effects in 3 cases. Six patients broke off their treatment because of side-effects ascribed to tolfenamic acid. However, laboratory tests failed to show any significant changes caused by this drug. One case of reversible thrombopenia was seen in a patient who had also received gold treatment. On the whole, the clinical effect was found to be good, and tolfenamic acid appeared to be well suited for long-term symptomatic treatment of rheumatics.

Protracted continuous infusion of 5-fluorouracil in combination with doxorubicin, vincristine, and oral cyclophosphamide in advanced breast cancer.

Several studies suggest that protracted continuous infusion constitutes an important way to optimize the dose and the efficacy of 5-fluorouracil (5-FU) in metastatic cancer. Eighty-three women aged 27-76 (median age 55) with metastatic breast cancer were treated every 4 weeks with a continuous ambulatory venous infusion of 5-FU 350 mg/m2/day and oral cyclophosphamide 100 mg/m2/day over 15 days. The continuous therapy was associated with a weekly administration of vincristine (0.8 mg/m2) and doxorubicin (15 mg/m2) on day 1, day 8, and day 15. Cycles were repeated every 28 days. Thirty-four patients were treated in first-line metastatic chemotherapy and 49 in second-line. Toxicities included: mucositis (grade > or = 2) 23%, diarrhea (grade > or = 2) 7%, a hand-foot syndrome (grade > or = 2) 9%, alopecia (grade 3) 21%, neurological (grade > or = 2) 4%, grade 3 and 4 leukopenia 29%, and grade 3 and 4 thrombopenia 8%. Heart toxicity was only 3%. Catheter infection was observed in 1 case and 7 patients experienced thrombosis. The overall objective response rate (OR) was 48% and the complete response rate was 23%. The median duration of response was 10 months. The median survival was 16 months. Activity was better in naive than pretreated women (respectively, 55% and 42% of OR, p = 0.21). Analysis of responses according to the metastatic sites shows the pronounced efficacy on soft tissue diseases (skin recurrences 42%, lymph nodes 52%), and also in visceral metastases (hepatic 36%, lung 34%).

Idarubicin and high dose cytarabine: a new salvage treatment for refractory or relapsing non-Hodgkin's lymphoma.

Twenty three patients with relapsing (n = 11) or refractory (n = 12) non-Hodgkin's lymphoma (NHL) to one or two prior anthracycline based combination chemotherapy regimens were treated as second or third line regimen with 3 induction cycles of Idarubicin (IDA) (7 mg/m2/d i.v. d1-d3) and high dose cytarabine (HD Ara-C) (1 g/m2/12 h i.v. d1-d3), each cycle was repeated every 3 weeks. Responding patients received a maintenance therapy with monthly cycles of IDA: 15 mg/m2 d1-d3, Etoposide 100 mg/m2 d1-d3, both by oral route. Twenty two patients are evaluable and we observed 13 CR and 1 PR with an overall response rate of 61% (14/23: 95% Cl = 38.5% 80.3%). The median time to progression was 32 months (6.5 - 63 + m.). The response rate to IDA-HD Ara C was not different for patients with (n = 14) or without (n = 9) objective response to the last prior therapy. The main toxicity was hematological: all patients experienced grade 4 neutropenia and 22 patients had grade 4 thrombopenia, but there were no toxic deaths. IDA and HD-Ara-C combination is highly effective in refractory or relapsed. NHL. As hematological toxicity was the limiting factor for further escalation of dose-intensity, further studies might include hematopoietic growth factors support in the therapeutic scheme.

A phase II study of interleukin-2 in 49 patients with relapsed or refractory acute leukemia.

In this report we present the results of a multicenter phase II study of high-dose recombinant Interleukin-2 (rIL-2) in patients with refractory or relapsed acute leukemia. Forty-nine patients with acute myeloid leukemia (AML: 30 patients) or acute lymphoblastic leukemia (ALL: 19 patients) were included. Median age was 30 years (range: 4-71). Four patients were treated for primary refractory disease and 45 for relapsed disease (16 patients > 2nd relapse). Twenty-four patients (49%) had previously received bone marrow transplantation (allogeneic: 5, autologous: 19). Patients were scheduled to receive three 5-day cycles of rIL-2 given every other week. rIL-2 was administered as bolus I.V. infusion of 8 x 10(6) UI/m2 every 8 hours during cycle I and every 12 hours during cycles 2 and 3. Patients received a mean of 76% of rIL-2 planned dose. Main toxicity was hematologic (grade IV thrombopenia: 84%). Hemodynamic and metabolic toxicities lead to treatment discontinuation in 10 patients (20%). Strong immune activation was achieved including a significant increase in activated T-cells and Lymphokine-Activating-Killer cell (LAK) activity. Twenty-seven out of 30 AML patients could be evaluated for response: 2(7%) achieved complete remission (CR) which lasted 3 and 4 months. No response was observed in the 18 assessable ALL patients, most of whom (77 %) presented absolute drug resistance. These results show that this high dose rIL-2 regimen induces significant biological effects and provides some anti-leukemic activity in patients with advanced leukemia. Considering the severe toxicity observed and the limited remission rate achieved here, rIL-2 does not appear to be a valuable therapeutic option for such patients. However, the undoubted anti-leukemic activity of this cytokine invites further investigation especially in the minimal residual disease situation.

Acute diquat intoxication. Interest of its repeated determination in urine and the evaluation of renal proximal tubule integrity.

A 33-year old farmer ingested approximately 300 ml of a 20% solution of diquat along with about 80 mg flunitrazepam. The patient presented neurological (coma grade I), digestive (oro-pharyngeal erosions, ileus), hepatic (cytolysis), hematological (thrombopenia) and renal (tubular dysfunction) signs. Plasma creatinine did not exceed 1.22 mg/dl (upper normal value), but retinol binding protein level in urine (a marker of renal tubular dysfunction) reached a value of 337 mg/d (normal values less than 300 micrograms/d). Its level returned to normal value 18 days after the ingestion. Four hours after the poisoning, diquat level in blood amounted to 10.4 mg/l, but its level was below the detection limit (0.2 mg/l) 6 hours later. In urine, however, diquat was detected until day 13. The following therapy was applied: ventilation (FiO2:0.21), gastro-intestinal lavage, hemoperfusion, anti-oxidants and prolonged forced diuresis. The patient made an uneventful recovery. intestinal washout must be applied with caution since an ileus is a classical complication of diquat poisoning. Hemoperfusion was found to be of little value. The interest of prolonged application of forced diuresis is suggested by the detection of diquat in urine for about 2 weeks along with the presence of biological signs of renal tubular dysfunction.

Phase II trial of cisplatin, 5-fluorouracil and folinic acid using a weekly 24-h infusion schedule for locally advanced head and neck cancer: a pharmacokinetic and clinical survey.

The objective of this phase II prospective study was to determine the efficacy and the toxicity of a new schedule of neoadjuvant chemotherapy in locally advanced squamous cell carcinomas of the head and neck (SCCHN). Thirty-three patients were included in this study (13 stage III and 20 stage IV). Cisplatin (CDDP: 35 mg/m2), 5-fluorouracil (FU: 2 g/m2) and folinic acid (FA: 500 mg/m2) were administered by continuous i.v. infusion for 24 h, once every 7 days. Six cycles of neoadjuvant chemotherapy were planned before definitive locoregional treatment. A total of 195 cycles were analysed for toxicity: mucositis was observed in 11/195 cycles; 12/195 showed diarrhea and vomiting occurred in 10/195. The myelosuppression was low (neutropenia: 4/195, thrombopenia: 3/195). One treatment-related death was observed after grade IV neutropenia at the fourth cycle. Thirty-two patients were evaluated for response. The objective response rate was 87%, with 50% complete response (CR) and 37% partial response. Failure rate was 13% (stable disease). There was no progressive disease. Survival and DFS duration were significantly higher in cases of CR or in laryngeal localization. The average peak plasma levels for the 6 courses of CDDP, 5-FU, dl-FA and mTHF were 4.9+/-0.76 microM, 4.1+/-0.54 microM, 29.1+/-2.4 microM and 4.8+/-0.31 microM respectively. Therefore, the administration of the 3 drugs by a 24 h continuous i.v. infusion reached an efficient level for drug modulation. This new weekly schedule is as active as other standard therapy in the disease but significantly less toxic as neoadjuvant chemotherapy in advanced untreated SCCHN. With the low toxicities observed with this schedule, additional treatment (surgery and/or radiotherapy) is warranted to evaluate the impact on overall survival of SCCHN.

Doxepin in the treatment of primary insomnia: a placebo-controlled, double-blind, polysomnographic study.

BACKGROUND: Over recent years, the use of antidepressants for the symptomatic treatment of insomnia has grown substantially, but controlled studies are still lacking. Our study is the first investigation to prove objective efficacy and tolerability of low doses of a sedating antidepressant in a randomized, double-blind, and placebo-controlled manner in patients with primary insomnia. METHOD: Forty-seven drug-free patients meeting DSM-IV criteria for primary insomnia (mean +/- SD duration of complaints = 11.2+/-9.7 years) received either 25-50 mg of the tricyclic antidepressant doxepin or placebo for 4 weeks followed by 2 weeks of placebo withdrawal. Sleep was measured by polysomnography at baseline and the first night of application, at 4 weeks of treatment and the first to third night of withdrawal, and after 2 weeks of withdrawal. RESULTS: In the doxepin-treated patients who completed the study (N = 20, 47.6+/-11.3), medication significantly increased sleep efficiency after acute (night 1, p < or = .001) and subchronic (night 28, p < or = .05) intake compared with the patients who received placebo (N = 20, 47.4+/-16.8 years of age). Latency to sleep onset was not affected since the patients had normal baseline sleep latencies. Investigators found doxepin to cause significantly (p < or = .05) better global improvement at the first day of treatment. Patients rated sleep quality (p < or = .001) and working ability (p < or = .005) to be significantly improved by doxepin during the whole treatment period. Overall rebound in sleep parameters was not observed, but patients with severe rebound insomnia were significantly more frequent in the doxepin group (night 29, p < .01, night 30, p < or = .01; night 31, p < or = .05). No significant group differences in side effects were found, but 2 doxepin-treated patients dropped out of the study due to specific side effects (increased liver enzymes, leukopenia, and thrombopenia). CONCLUSION: The results support the effectiveness of low doses of doxepin to improve sleep and working ability in chronic primary insomniacs, although subjective effects were light to moderate, and in some patients, rebound insomnia and specific side effects have to be considered.

[Neoadjuvant chemotherapy FEC-HD in locally advanced breast cancer].

The tolerance and the clinical and histological efficacy of a neoadjuvant chemotherapy FEC-HD including hematopoietic growth factors have been studied in 40 patients with stade II or III breast cancer between February 1991 and February 1997. Four courses were given, every 21 days, with 5-fluorouracil (750 mg/m2/day D1 to D4 by continuous infusion), epirubicin (35 mg/m2/day D2 to D4) and cyclophosphamide (400 mg/m2/day D2 to D4) with G-CSF (5 mug/kg/day D6 to D15). The surgery was performed 3 or 4 weeks after the end of the chemotherapy. All patients had radiotherapy. The neoadjuvant chemotherapy induced 37.5% CR, 45% PR, and 15% SD. In 40% of the patients, the surgery was conservative. An histological CR was obtained in 15% with no axillary involvement one time out of two. There was intraductal carcinoma without invasive carcinoma in 7.5%. There was no differences between the response of inflammatory and non inflammatory tumors. One hundred and fifty-eight courses have been delivered. A grade 3 or 4 leuconeutropenia, anemia and thrombopenia have been observed in respectively 34.6%, 6.3% and 8.8% of the courses. A grade 3 or 4 mucositis has been noticed in 2.5% of the courses. A febrile granulocytopenia has occurred in 3.8% of the courses. The median survival without metastatic progression was 48 months and the median overall survival was not achieved. In stade II and III breast cancer, neoadjuvant chemotherapy with FEC-HD obtains an important histological response with an acceptable toxicity. The role of the dose-intensity increase on survival remains to be determined.

[Studies on the problem of septic thrombocytopenia and reactive thrombocytosis in obstetrical patients].

During the first 24 hours of septicaemia the platelet count decreases, but in about a week increases again resulting a significant reactive thrombocytose. According to the results of platelet spreading test, the thrombopenia is caused by consumption of young platelets. During the course of increase of platelet count the number of haemostatically most active, newly formed platelets exceeds, and this is why in the periode of reactive thrombocytosis deep-vein thromboses may occure against Heparin or oral anticoagulant treatment.

A restrictive platelet transfusion policy allowing long-term support of outpatients with severe aplastic anemia.

The threshold for prophylactic platelet transfusions in patients with hypoplastic thrombopenia generally recommended in the standard literature is 20,000 platelets/microL. A more restrictive transfusion policy may be indicated in patients with chronic severe aplastic anemia (SAA) in need of long-term platelet support. We evaluated the feasibility and safety of a policy with low thresholds for prophylactic transfusions (</=5,000 platelets/microL in stable patients; 6,000 to 10,000 platelets/microL in cases with fever and/or hemorrhagic signs) combined with progressive lengthening of transfusion intervals (up to at least 7 days irrespective of the interim course of platelet counts). The study was based on a retrospective analysis of a total of 18,706 patient days with platelet counts </=10,000/microL in patients with chronic SAA treated (for more than 3 months) on an outpatient basis. Altogether, 1,135 platelet transfusions were given, 88% at counts </=10, 000/microL and 57% at counts </=5,000/microL. The mean transfusion interval was 10 days. During the period of observation, three major nonlethal bleeding complications occurred, which could be well controlled. We conclude that the restrictive policy with low transfusion thresholds and prolonged transfusion intervals proved feasible and safe in chronic SAA patients.

[Adverse effects of quinine in the treatment of leg cramps].

In France, three over-the-counter products containing quinine exist to treat cramps. This study aims to analyse data on spontaneous reports to the French System of Pharmacovigilance of adverse reactions to quinine drug products. From 1985 to 1996, we reviewed 58 adverse reaction reports. Most involved hypersensitivity reactions: rash, pruritus, generalized anaphylaxis, thrombopenia and hepatitis. Cinchonism is rarely observed at the usually low dose of quinine in this indication. No fatal outcome has been notified as described in the USA and Australia. The Food and Drug Administration (FDA) decided that prescription of quinine drug products should not be used any longer in the treatment of muscle cramps. Immuno-allergic reactions are potentially serious and must be avoided by giving clear information to patients and prescribers, and looking into the history of such reactions in patients in respect of the quinine drug and also tonic water.

[Difficulties in the detection of heparin-induced thrombocytopenia type II].

We report about a 29 year old female who developed right-sided leg vein thrombosis over three levels. Thrombectomy was attempted followed by intravenous anticoagulation with heparin. The platelet count dropped acutely from 176,000/microliter to 11,000/microliter after the sixth day. A lung perfusion-ventilation-scintigraphy suggested recent pulmonary embolism by lateral, predominantly right-sided perfusion deficits. ACT scan of the pelvic region showed rethrombosis of the right common iliac vein. The clinical suspicion of heparin-induced thrombocytopenia (HIT) type II was confirmed by a positive heparin-induced platelet aggregation test and the detection of antibodies by heparin-platelet factor 4-ELISA. The patient was treated with lepirudin at body-weight-adapted dose. After recovery of the platelet count to 102,000/microliter within seven days the treatment was changed to Orgaran after exclusion of immunologic cross reactivity. An overlapping oral anticoagulation with Marcoumar was initiated. Although HIT type II usually develops over a few days, acute thrombopenia can also occur. There is therefore no safe diagnostic interval permitting a timely detection.

[Serum and pulmonary angiotensin converting enzyme as a marker of acute lung injury in an experimental model of adult respiratory distress syndrome].

OBJECTIVE: To know if the determination of the angiotensin converting enzyme in serum (SACE) and lung (LACE) may be useful as a marker of acute lung injury (ALI) in the adult respiratory distress syndrome (ARDS). METHOD: By reproducing in a experimental model of ALI with oleic acid in dogs which simulate the early stage of ARDS, we have correlated the pathologic and analytical changes observed with the results of the determinations of SACE and LACE. RESULTS: We have found sequential pulmonary lesions (congestion, edema, hemorrhage polynuclear infiltration and thrombosis) and biological alteration (hypoxemia, pulmonary hypertension, early leukopenia and final leukocytosis, thrombopenia and hypofibrinogenemia) that reproduce the typical changes of ARDS, together with the decrease of SACE--slow and progressive--and LACE--abrupt in the onset and maintained during the experiment--. CONCLUSIONS: The LACE is a good marker of the beginning of the lesion because its decrease coincides with the first pathological changes (congestion) and with the hypoxemia, pulmonary hypertension and leukopenia, maintained without changes, during the whole experiment. On the other hand, the SACE corresponds as an inespecifical reactant, marker of acute inflammation and loss of pulmonary endothelium, because its progressive decrease evolutioned with the pathological lesions and the analytical changes. In conclusion, the sequential determination of SACE has a prognostic and evolutive value in comparison with the LACE, which has a diagnostic value from the beginning of the experiment of ALI and maintained throughout.

[Fatal fulminating hepatitis due to Herpes simplex virus type 2 in a young immunocompetent female].

Fulminant herpes simplex viral hepatitis is uncommon in immunocompetent subjects. A 24-year-old woman presenting hepatomegaly with fever was hospitalized after returning from a trip to southern Africa. The patient was neither pregnant nor immunocompromised. Because of recent tropical travel, differential diagnosis included alphabetic hepatotropic virus infection, yellow fever, African hemorrhagic fever, and arbovirus infection. After ruling out other common viral etiologies, a definitive diagnosis of herpes simplex viral infection was made on the basis of clinical and laboratory findings showing high fever, leukopenia, and thrombopenia; of histological examination of the native liver after transplantation showing non-inflammatory confluent focal hemorrhagic necrosis; and on serologic tests demonstrating seroconversion for herpes simplex virus type 2. Outcome after transplantation was rapidly fatal but the death was not directly related to infection. The most likely etiology of fulminant hepatitis in a young woman returning from travel in a tropical area is hepatitis virus B or hepatitis virus E in cases involving pregnancy. However herpes simplex virus should be included in differential diagnosis even in immunocompetent subjects.

Radioimmunotherapy of small cell lung carcinoma with the two-step method using a bispecific anti-carcinoembryonic antigen/anti-diethylenetriaminepentaacetic acid (DTPA) antibody and iodine-131 Di-DTPA hapten: results of a phase I/II trial.

As small cell lung carcinoma (SCLC) is frequently a widespread disease at diagnosis, highly radiosensitive and often only partially responsive to chemotherapy, radioimmunotherapy (RIT) would appear to be a promising technique for treatment. We report the preliminary results of a Phase I/II trial of RIT in SCLC using a two-step method and a myeloablative protocol with circulating stem cells transplantation. Fourteen patients with proved SCLC relapse after chemotherapy were treated with RIT. They were first injected i.v. with a bispecific (anti-carcinoembryonic antigen/anti-diethylenetriaminepentaacetic acid) monoclonal antibody (20-80 mg in 100 ml of saline solution) and then 4 days later with di-(In-diethylenetriaminepentaacetic acid)-tyrosyl-lysine hapten labeled with 1.48-6.66 GBq (40-180 mCi) of I-131 and diluted in 100 ml of saline solution. In patients receiving 150 mCi or more, circulating stem cells were harvested before treatment and reinfused 10-15 days later. Treatment response was evaluated by CT and biochemical data during the month before and 1, 3, 6, and 12 months after treatment. All patients received the scheduled dose without immediate adverse reactions to bispecific antibody or 1-131 hapten. Toxicity was mainly hematological, with two cases of grade 2 leukopenia and three cases of grade 3 or 4 thrombopenia. Body scanning 8 days after injection of the radiolabeled hapten generally showed good uptake at the tumor sites. Estimated tumor dose was 2.6-32.2 cGy/mCi. Among the 12 patients evaluated to date, we have observed 9 progressions, 2 partial responses (one almost complete for 3 months), and 1 stabilization of more than 24 months. Efficiency and toxicity were dose-related. The maximal tolerable dose without hematological rescue was 150 mCi. These preliminary results are encouraging, and dose escalation is currently continuing to reach 300 mCi. RIT should prove to be an interesting therapeutic method for SCLC, although repeated injections and hematological rescue will probably be required, as well as combination with other treatment modalities.
