Large granular lymphocyte proliferative disease: 21 Belgian cases and review of the literature.

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

Pathogenic tracks in fatigue syndromes.

This review analyses the recent literature devoted to two related fatigue syndromes: chronic fatigue syndrome (CFS) and acute onset postviral fatigue syndrome (PVFS). The articles are grouped into five pathogenic tracks: infectious agents, immune system, skeletic muscle, hypothalamo-pituitary-adrenal (HPA) axis and psychiatric factors. Although a particular infectious agent is unlikely to be responsible for all CFS cases, evidence is shown that host-parasite relationships are modified in a large proportion of patients with chronic fatigue. Antibody titres against infectious agents are often elevated and replication of several viruses could be increased. Chronic activation of the immune system is also observed and could be due to the reactivation of persistent or latent infectious agents such as herpes viruses (i.e. HHV-6) or enteroviruses. It could also be favorised by an impaired negative feedback of the HPA axis on the immune system. A model is proposed where the abnormalities of the HPA axis are primary events and are mainly responsible for a chronic activation of the immune system which in turn induces an increased replication of several viruses under the control of cellular transcription factors. These replicating viruses together with cytokines such as TNF-alpha would secondarily induce functional disorders of muscle and several aspects of asthenia itself.

The efficacy and safety of once-daily Kytril (granisetron hydrochloride) tablets in the prophylaxis of nausea and emesis following fractionated upper abdominal radiotherapy.

This multicenter, randomized, double-blind study compared the efficacy and safety of once-daily oral granisetron 2 mg (n = 134) and placebo (n = 126) as prophylaxis for nausea and emesis in patients receiving upper abdominal fractionated radiotherapy. Patients were scheduled to receive 10-30 fractions of radiotherapy; granisetron (two 1-mg tablets) or placebo was administered 1 hr before radiotherapy on each scheduled treatment day. Treatment comparisons were made at 24 hr and at 10 and 20 fractions. Patients treated with granisetron experienced greater emetic control than those treated with placebo as evidenced by median times to first emesis (35 vs. 9 days, p < 0.001) and first nausea (11 vs. 1 day, p < 0.001). Overall endpoint analysis showed that proportionally more granisetron than placebo patients were emesis free (57.5% vs. 42.1%, p = 0.0047) and nausea free (30.6% vs. 16.7%, p = 0.0042). Furthermore, 25% more granisetron-treated than placebo-treated patients were emesis free and 20% more were nausea free on at least 80% of study treatment days. The most commonly reported adverse experiences in granisetron-treated patients were diarrhea, asthenia, and constipation. These findings demonstrate that a once-daily, 2-mg dose of oral granisetron is well tolerated and significantly more effective than placebo in preventing nausea and emesis induced by fractionated radiotherapy to the upper abdomen.

Toxicity of a 24-hour infusion of gemcitabine in biliary tract and pancreatic cancer: a pilot study.

The antitumor activity of gemcitabine is not dose-response related but schedule-dependent. Based on the results of a published phase I study in patients with nonsmall-cell lung cancer we started a pilot study of a 24-hr infusion of gemcitabine in patients with adenocarcinoma of the pancreas and biliary tract cancer. Twenty-five patients were enrolled and received a 24-hr infusion of gemcitabine once weekly on three consecutive out of 4 weeks. Dose levels of gemcitabine ranged from 100 to 150 mg/m2. One of 13 chemotherapy-naive patients had a partial response. Dose-limiting toxicity (DLT) was thrombocytopenia in pretreated patients and neutropenia in chemotherapy-naive patients. Other toxicities were oral mucositis, fever, flu-like symptoms, and asthenia. Maximum tolerated dose (MTD), especially in pretreated patients, was 100 mg/m2.

Vinorelbine and cisplatin for metastatic breast cancer: a salvage regimen in patients progressing after docetaxel and anthracycline treatment.

PURPOSE: To assess the antitumor efficacy and safety of a combination of vinorelbine (VNR) and cisplatin in patients with metastatic breast cancer previously treated with anthracyclines and docetaxel. PATIENTS AND METHODS: Thirty-six patients with assessable metastatic breast cancer previously treated with anthracyclines and docetaxel (adjuvant n = 1, palliative n = 20, both n = 15) were studied. Cisplatin was given at 75 mg/m2 on day 1 followed by 25 mg/m2 VNR on days 1 + 8 in a 5-minute i.v. infusion. Courses were repeated every 3 weeks. Treatment was continued until disease progression, excess toxicity, or patient refusal. Patients were classified according to their response to anthracyclines according to criteria published previously: 1) Anthracycline and/or docetaxel resistant were patients who progressed during treatment with anthracyclines and docetaxel or within 4 months after cessation of treatment (metastatic). In addition, adjuvant patients who progressed within 6 months after completion of chemotherapy belong to this group. 2) Anthracycline and/or docetaxel relapsed were either metastatic patients who responded initially and then progressed after 4 months of completing an anthracycline- and docetaxel-based chemotherapy or patients who progressed after 6 months from completion of anthracycline/docetaxel-based adjuvant chemotherapy. RESULTS: Two patients (5.6%) achieved a complete response (CR) and 15 patients (41.6%) achieved a partial response (PR), for an overall response rate (OR) of 47.2% (95% confidence interval, 31-63). Of 18 patients relapsed to anthracycline/docetaxel, 2 had a CR (11%) and 8 a PR (44.4%), giving an objective response of 55.5%. Stable disease (SD) was observed in one patient (5.5%); seven patients had progressive disease (PD) (39%). Among the 18 resistant patients, 7 PRs (39%) were observed (p = 0.5), one patient (5.5%) had stable disease, 10 patients (55.5%) progressed. The median time to progression (TTP) was 16 weeks and median overall survival 36 weeks. Relapsed patients had a longer TTP than resistant patients (24 vs. 8 weeks, p = 0.05) but similar survival (48 vs. 24 weeks, p = 0.173). All patients were assessed for toxicity. The main toxicity was neutropenia grade 3 and 4 in 47% of patients. Febrile neutropenia requiring hospitalization was absent. There were no treatment-related deaths. Thrombocytopenia grade 3 and 4 occurred in four patients (11%). Phlebitis, orthostatic hypotension, and asthenia, all reversible, were observed in 3% of patients, respectively. CONCLUSION: This cisplatin/VNR regimen is well tolerated and active in patients who failed anthracyclines and docetaxel treatment. The response rate, TTP, and survival data are high and indicate that cisplatin/VNR may have a place as salvage treatment in this group of patients. If these results can be verified in multi-institutional trials, this combination of drugs would merit investigation as part of a first-line therapy in breast cancer.

A phase I human trial of mitoguazone and gemcitabine sequential bi-weekly treatment of cancer patients.

Our previous studies have demonstrated the existence of synergism in a combination therapy using mitoguazone and gemcitabine when the mitoguazone is administered 24 hours before gemcitabine. Based on the cell culture and animal experimental results, a phase I clinical trial was performed in order to determine the toxicity of the combined treatment. Mitoguazone and gemcitabine were administered sequentially: mitoguazone on day 1 and gemcitabine on day 2. This cycle was repeated every 2 weeks. The dosages of these two drugs were varied between patients. Ten patients were enrolled in the study. Six patients began treatment at dose level 1 (mitoguazone 500 mg/m2, gemcitabine 1500 mg/m2), three at dose level 2 (mitoguazone 500 mg/m2, gemcitabine 2000 mg/m2), and one at dose level 3 (mitoguazone 600 mg/m2, gemcitabine 2000 mg/m2). Dose-limiting toxicity (DLT) was only observed in two patients treated at dose level 1 and one patient treated at dose level 3, while all the other patients only experienced nonhematologic toxicity, such as asthenia and mucositis. Two melanoma patients showed responses (one partial and one minor) to the treatment. One lymphoma patient also showed a brief partial response. This phase I trial indicated that the combination of mitoguazone and gemcitabine had limited but noticeable activity for treatment of cancer patients. Further study on the toxicity and on the effect of the scheduled mitoguazone-gemcitabine combination is needed.

Spotless rickettsiosis caused by Rickettsia slovaca and associated with Dermacentor ticks.

The pathogenic role of Rickettsia slovaca was first demonstrated in 1997 in a patient who presented with a single inoculation lesion of the scalp and enlarged cervical lymph nodes after receiving a bite from a Dermacentor tick. Subsequently, we evaluated the occurrence of R. slovaca infections among patients living in France and Hungary who presented with these symptoms. R. slovaca infections were confirmed by polymerase chain reaction (PCR) in 17 of 67 enrolled patients. Infections were most likely to occur in patients aged <10 years and in patients who were bitten during the colder months of the year. The median duration of incubation for the disease was 7 days. Fever was present in only 2 patients, and only 1 patient developed a rash. Sequelae included persistent asthenia (3 cases) and localized alopecia (4 cases). Immunofluorescence and/or Western blot analysis detected antibodies in 50% of tested patients. Three Dermacentor ticks obtained from patients revealed R. slovaca by PCR.

Treatment of Ebola hemorrhagic fever with blood transfusions from convalescent patients. International Scientific and Technical Committee.

Between 6 and 22 June 1995, 8 patients in Kikwit, Democratic Republic of the Congo, who met the case definition used in Kikwit for Ebola (EBO) hemorrhagic fever, were transfused with blood donated by 5 convalescent patients. The donated blood contained IgG EBO antibodies but no EBO antigen. EBO antigens were detected in all the transfusion recipients just before transfusion. The 8 transfused patients had clinical symptoms similar to those of other EBO patients seen during the epidemic. All were seriously ill with severe asthenia, 4 presented with hemorrhagic manifestations, and 2 became comatose as their disease progressed. Only 1 transfused patient (12.5%) died; this number is significantly lower than the overall case fatality rate (80%) for the EBO epidemic in Kikwit and than the rates for other EBO epidemics. The reason for this low fatality rate remains to be explained. The transfused patients did receive better care than those in the initial phase of the epidemic. Plans should be made to prepare for a more thorough evaluation of passive immune therapy during a new EBO outbreak.

Ebola hemorrhagic fever in Kikwit, Democratic Republic of the Congo: clinical observations in 103 patients.

During the 1995 outbreak of Ebola hemorrhagic fever in the Democratic Republic of the Congo, a series of 103 cases (one-third of the total number of cases) had clinical symptoms and signs accurately recorded by medical workers, mainly in the setting of the urban hospital in Kikwit. Clinical diagnosis was confirmed retrospectively in cases for which serum samples were available (n = 63, 61% of the cases). The disease began unspecifically with fever, asthenia, diarrhea, headaches, myalgia, arthralgia, vomiting, and abdominal pain. Early inconsistent signs and symptoms included conjunctival injection, sore throat, and rash. Overall, bleeding signs were observed in <45% of the cases. Typically, terminally ill patients presented with obtundation, anuria, shock, tachypnea, and normothermia. Late manifestations, most frequently arthralgia and ocular diseases, occurred in convalescent patients. This series is the most extensive number of cases of Ebola hemorrhagic fever observed during an outbreak.

First outbreak of human trichinellosis caused by Trichinella pseudospiralis.

This is the first report of an epidemic of human infection with Trichinella pseudospiralis. An outbreak of trichinellosis affecting 59 individuals, of whom one died, occurred in southern Thailand during 1994-1995. The source of this epidemic was raw pork from a wild pig that was distributed to villagers by a local hunter. The most striking clinical features among 50 individuals who could be followed were muscular swelling, myalgia, and asthenia persisting for > 4 months. These were associated with significant elevations of creatine phosphokinase and lactate dehydrogenase levels. All patients had Trichinella-specific IgG antibodies in an enzyme-linked immunosorbent assay. Muscle biopsies, performed in six cases, showed nonencapsulated, actively migrating Trichinella larvae. Experimental infection of mice with larvae from human biopsies revealed nonencapsulated muscle larvae consistent with T. pseudospiralis. The identification of muscle larvae from a human specimen by random amplified polymorphic DNA analysis confirmed the causative agent to be T. pseudospiralis. Patients seemed to respond best to treatment with albendazole.

Myasthenia gravis during low-dose IFN-alpha therapy for chronic hepatitis C.

We describe the case of a 56-year-old man who had high aminotransferase levels and anti-hepatitis C virus (HCV) antibodies. He underwent liver biopsy and biochemical screening to evaluate whether he would benefit from interferon (IFN) treatment. The patient was discharged with a diagnosis of HCV-related active chronic hepatitis, skin porphyria, and type 2 diabetes. On December 5, 1995, he began therapy with recombinant IFN-alpha at a dose of 3 MIU three times a week. He stopped this therapy in February 1996 because of asthenia, diplopia, headache, and anxiety. During IFN therapy, he had normal aminotransferase levels and no detectable HCV RNA, a condition that persists to the present. Between March and May 1996, the patient was admitted several times to a neurology clinic, where myasthenia gravis was diagnosed and treatment with pyridostigmine and cyclosporine was initiated. This case and others indicate that caution should be exercised in administering IFN because low doses can be correlated with myasthenia gravis in patients without malignancies.

Liver cirrhosis after prolonged therapy with IFN-alpha plus interleukin-2 in a metastatic renal cancer long-term survivor.

Interleukin-2 (IL-2) therapy is associated with serious toxic effects on the cardiopulmonary system. Less frequent toxicity is described in liver and the gastrointestinal system. A case of severe liver toxicity is described in a patient who underwent long-term immunotherapy with IL-2 (4.5 MU/m(2) s.c. daily, 5 days per week for 6 weeks, with 4 weeks of interval) plus interferon-alpha (IFN-alpha) (3 MU s.c. t.i.w., also covering the intervals between IL-2 cycles) for a metastatic renal carcinoma. A review of the literature is provided. The patient tolerated well the immunotherapy scheduled with apparently only a World Health Organization (WHO) G3 anemia and a G2 asthenia and is still alive, with a disease-free survival of 28 months. Notwithstanding a complete absence of liver function test abnormality during all scheduled clinical controls, the patient developed portal hypertension due to liver cirrhosis, which was histologically demonstrated. All common etiologic viral and toxic agents were ruled out. Long-term IL-2 therapy can induce liver cirrhosis. The appearance of liver and spleen enlargement during IL-2 therapy can be considered an indicator of liver damage. Thus, in this setting, closer monitoring is warranted despite normal liver function tests.

Chemo-biotherapy with 5-fluorouracil, leucovorin, and alpha interferon in metastatic carcinoma of the colon--a Cancer Biotherapy Research Group [CBRG] phase II study.

BACKGROUND: Biochemical modulation of 5-Fluorouracil activity with Leucovorin has been well documented in colorectal cancer. Several studies have shown increased efficacy of 5-fluorouracil in combination with alpha interferon. We therefore initiated a phase II trial of dual modulation of 5-fluorouracil with leucovorin and alpha interferon to evaluate outcomes in patients with metastatic carcinoma of the colon. METHODS: Patients with metastatic colon carcinoma with expected survival > 4 months and performance status of ECOG < or = 2 were treated weekly with Leucovorin 400 mg i.v. followed by 5-FU 600 mg/m2 i.v. bolus. Alpha interferon 3-9 million units was administered subcutaneously every Monday, Wednesday and Friday. Patients were analyzed for toxicity, tumor response and survival. RESULTS: Sixteen patients with a median age of 66 years were treated. Three patients were not evaluable for response but were evaluable for toxicity. Grades 3 and 4 toxicities were neutropenia, diarrhea, mucositis, nausea and vomiting, fatigue, fever, asthenia and elevated hepatic enzymes. One patient died from complications associated with diverticulitis and neutropenia. Objective response rate was 23% (95% confidence interval 4-46%) and median survival was 11.5 months (95% confidence interval 6.3-19 months). Thirty-eight percent of the patients were alive at one year and 19% at two years. CONCLUSION: The combination of 5-fluorouracil, leucovorin and alpha interferon as administered in this phase II study did not result in enhanced response rate or survival. However this regimen was associated with considerable toxicity.

Clinical results of leukocyte interferon-induced tumor regression in resistant human metastatic cancer resistant to chemotherapy and/or radiotherapy-pulse therapy schedule.

The efficacy of Human 6 IFN (HLIFN) given in a pulse fashion was determined in a phase II study. Ninety-one cancer patients were evaluated (9 myeloma, 12 breast, 14 prostate, 9 melanoma, 4 renal, 6 astrocytoma, 7 ovarian, 9 large bowel, 7 gastric, 14 head and neck). They all had advanced progressive cancer that was resistant to chemotherapy and/or radiotherapy. Patients were treated by intramuscular injection of 6 X 10(2) I.U./m2 for three consecutive days every four weeks. 84 patients were evaluable. Complete clinical response was obtained in 23 patients (4 myeloma, 2 breast, 5 prostate, 1 melanoma, 1 renal, 2 astrocytoma, 2 ovarian, 2 large bowel, 1 gastric, 3 head and neck). Partial responses were observed in 35 patients (3 myeloma, 7 breast, 6 prostate, 4 melanoma, 1 renal, 2 astrocytoma, 3 ovarian, 4 head and neck). Objective responses were related (P less than 0.01) to serum IFN level, with complete and partial responses (P less than 0.01) more commonly seen in those patients whose serum IFN levels at two hours were in the range of 1000 to 1650 I.U./ml. Side effects resulting from pulse IFN were acceptable for this group of patients and consisted of fever, transient chills, malaise and asthenia, and transient thrombocytopenia and leukocytopenia. The extent of fever was directly related (P less than 0.01) to response, and was most elevated in patients who achieved objective responses. IFN administered in a pulse fashion appears to be more effective than daily IFN and merits further evaluation.

Multicenter randomized, controlled study of intramuscular administration of interferon-beta for the treatment of chronic hepatitis C.

The intramuscular administration of interferon-beta (IFN-beta) at a dosage of 6 million units three times per week for 6 months has been evaluated in 90 patients included in a multicenter, randomized, controlled trial for the treatment of chronic hepatitis C. Transaminase levels were significantly reduced in IFN-beta-treated patients (p = 0.015) and were significantly lower with respect to those of the untreated controls (p = 0.040 at 6 months). Four treated (8%) and one untreated (2.5%) patients had normal transaminase values after 6 months. At study end (12 months), three quarters of the IFN-beta-treated patients had sustained transaminase normalization, whereas the untreated case had relapsed. Hepatitis C viremia was cleared in 6 (12%) treated patients but in none of the untreated controls (p = 0.058). Side effects of IFN-beta were infrequent (a mild flu-like syndrome in < 10%, asthenia in 16%, anorexia in 8%, headaches and weight loss in 8%, and hair loss in 4%). Leukocyte and platelet counts decreased during IFN-beta treatment, but no dose modifications were necessary. Such decreases were not statistically significant when compared with the levels in the untreated controls. Intramuscular IFN-beta at the dosage used has little efficacy in the treatment of chronic hepatitis C. Because of IFN-beta tolerance, higher doses and alternate routes of injection might prove beneficial for the treatment of this disease.

Long-term interferon-alpha therapy does not affect sex hormones in males with chronic hepatitis C.

The effects of interferon-alpha (IFN-alpha), given at a dosage of 6 MU thrice weekly for 12 months, on gonadal function were investigated in 18 males affected by chronic hepatitis C. Periodically, all patients were clinically monitored and questioned about sexual function. Gonadotropin and serum androgen concentrations (follicle-stimulating hormone, luteinizing hormone, total testosterone, free testosterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulfate, and sex hormone binding globulin) were tested every 3 months. Ten of 18 patients (55%) responded to IFN-alpha therapy. Serum total testosterone and sex hormone binding globulin values decreased slightly at the third month of treatment, then returned to baseline values. Serum free testosterone and other sex hormones remained essentially unchanged during IFN-alpha therapy. Four patients (22.2%) complained of sexual dysfunction (impaired libido, erectile failure, and impaired ejaculation), which was unrelated to any significant hormonal change and resolved after IFN therapy was stopped. Serum sex hormones values did not differ between responders and nonresponders to IFN-alpha. This study indicates that 12 months treatment with 6 MU of IFN-alpha thrice weekly does not significantly affect gonadal function in men with chronic hepatitis C. The sexual dysfunction observed could be ascribed to such other side effects of IFN as asthenia, fatigue, or anxiety, or it could have a psychologic basis.

Clinical studies with fluoxetine in obesity.

Fluoxetine is a highly specific serotonin reuptake inhibitor. In studies that used a dose of 60 mg once daily, fluoxetine-treated patients consistently had greater weight loss than placebo-treated patients. In six double-blind, placebo-controlled studies of 6-8 wk duration, mean weight changes on fluoxetine were approximately 0.5 kg/wk. Longer term studies have shown maximum mean weight loss to occur at 12-20 wk of therapy. Studies have consistently shown improvements in indices of glycemic control as well as weight loss in obese diabetic patients. Safety analysis has been performed on data from 3491 obese patients in controlled clinical trials of up to 52 wk duration. Adverse events with an incidence of greater than 5%, which were reported significantly more frequently by fluoxetine-treated patients, were headache, asthenia, nausea, diarrhea, somnolence, insomnia, nervousness, sweating, and tremor. Fluoxetine is effective, well tolerated, and safe in the treatment of obesity and obese diabetics.

Terazosin, a new selective alpha 1-adrenergic blocking agent. Results of long-term treatment in patients with essential hypertension.

The long-term treatment of essential hypertension with terazosin, a new once-a-day alpha 1-adrenergic blocking agent, was evaluated in 364 hypertensive patients who received total daily doses of 1 to 40 mg for 3 weeks to 56 months. Consistent mean decreases in supine and standing systolic and diastolic blood pressures were observed throughout the study for patients treated with terazosin as monotherapy (supine, 9 to 12/10 to 13 mm Hg; and standing, 12 to 18/11 to 14 mm Hg) or in combination with other antihypertensive agents (supine, 12 to 16/12 to 15 mm Hg; and standing, 16 to 22/13 to 19 mm Hg). The most commonly reported adverse experiences were dizziness, headache, asthenia, cold symptoms, and nasal congestion. Adverse effects and metabolic disorders often associated with diuretics and beta blockers such as sexual dysfunction, hyperglycemia, hyperuricemia, hypokalemia, or adverse lipid effects were seen infrequently during long-term treatment with terazosin as monotherapy. Overall, terazosin was shown to be effective, safe, and well tolerated by most patients.
