[Title]: Evaluation of effectiveness and tolerability of isosorbide mononitrate during a three-year period in patients with angina pectoris.
[Abstract]: The antianginal effect and tolerability of isosorbide mononitrate (ISMN), 20 mg 2-3 times daily, orally were investigated in an open study in 28 patients, suffering from coronary heart disease and stable angina pectoris. Ergometric exercise tests were carried out before treatment and 2 h after drug intake, every 3 months during the first year and at 6-month intervals during the following 2 years. At the conclusion of the 3-year study the reduction of ST-segment depression, which had amounted to 58% after 1 year, could be improved to 78% (p less than 0.01). The frequency of angina was markedly reduced during the treatment with ISMN. While 14 of the patients had more than 3 episodes per day prior to the study, 16 patients were symptom-free at the end of the three years' therapy, and none of the patients had more than 1 or 2 attacks per day. The consumption of sublingual nitroglycerin diminished by 94% after one year and by 98% after 3 years of therapy (p less than 0.01). Headache was the only adverse effect observed in some of the patients (at the initiation of the treatment only). In conclusion this study demonstrated (1) the good tolerability of ISMN, at the doses used, and (2) the fact that the antianginal efficacy may be enhanced during the course of the therapy.

[Title]: [Application of all-trans retinoic acid combining chemotherapy and As4S4 in the maintenance treatment of patients with acute promyelocytic leukemia].
[Abstract]: OBJECTIVE: To compare the efficacy of all-trans retinoic acid (ATRA) combining chemotherapy and As4S4 with ATRA combining chemotherapy for the maintenance treatment of patients with acute promyelocytic leukemia (APL). METHODS: Sixty patients with APL induced to complete remission by ATRA and consolidated by chemotherapy were randomly divided into two groups. Thirty patients as As4S4 group received ATRA + As4S4 + chemotherapy, and another thirty patients as non-As4S4 group were treated only with ATRA + chemotherapy as maintenance therapy. The therapeutic effects, side effects and PML-RARalpha gene expression were analyzed. RESULTS: The three-year continuous complete remission (CCR) rate was 90.0% for As4S4 group and 61.1% for non-As4S4 group, the difference being statistically significant. Significant difference was also found in the positive rate of PML-RARalpha fusion gene between the two groups. The side effects were mild. CONCLUSION: APL patients in maintenance therapy with ATRA + 6-MP + MTX + As4S4 can obtain a higher CCR.

[Title]: Liposome-encapsulated doxorubicin in combination with cyclophosphamide, vincristine, prednisone and rituximab in patients with lymphoma and concurrent cardiac diseases or pre-treated with anthracyclines.
[Abstract]: BACKGROUND: To assess the efficacy and safety of the combination of non-pegylated liposome-encapsulated doxorubicin (Myocet(R)) with cyclophosphamide, vincristine, prednisone and rituximab (R-COMP) in patients with aggressive non-Hodgkin's B-cell lymphomas. METHODS: Twenty-one patients were selected for the presence of negative concurrent clinical features such as cardiac comorbidity and/or previous treatment with anthracycline-based regimens. Liposome-encapsulated doxorubicin at a dose of 50 mg/m(2) was administered in association with cyclophosphamide (750 mg/m(2)), vincristine (1.4 mg/m(2)), prednisone (40 mg/m(2)) and rituximab (375 mg/m(2)) every 21 days for four to six cycles unless progression or unacceptable toxicity occurred. RESULTS: A complete response (CR) was obtained in 16/21 patients (76%), three patients achieved a partial response (14%), with an overall response rate of 90%. Two patients (10%) did not respond to therapy. After a median follow-up of 13 months (range 2-36 months), 2/16 CR patients relapsed, with a disease-free survival (DFS) of 78%. CONCLUSIONS: The replacement of doxorubicin with its non-pegylated liposomal pharmaceutical analogue was well tolerated and highly effective in inducing remission in this group of patients at high risk for cardiac toxicity or previously treated with anthracyclines. Its high tolerability and low incidence of cardiac events (only one patient) warrants further studies to confirm the clinical benefits of liposomal doxorubicin in this subset of patients.

[Title]: Neurologic complications in allogeneic bone marrow transplant patients receiving cyclosporin.
[Abstract]: Regimens using cyclosporin (CSP) and either methylprednisolone (MP) or methotrexate (MTX) have been useful in the prophylaxis of acute graft-versus-host disease (GVHD) after allogeneic bone marrow transplantation (BMT). However, CSP produces a number of side effects, including neurologic toxicity. A retrospective review of recipients of 239 BMTs given CSP-based prophylactic regimens revealed that 10 patients (4.2%, 95% confidence interval 0% to 10.4%) experienced a syndrome characterized by hypertension, severe visual disturbances, seizures and occipital lobe density changes on brain computed tomography (nine patients) or nuclear magnetic resonance imaging (one patient). Neurologic findings were reversible in all cases, usually after temporary discontinuation of CSP. Univariate analysis identified the following risk factors for neurotoxicity: use of unrelated or HLA-mismatched related donors, administration of etoposide (VP-16) or total body irradiation as part of conditioning, use of corticosteroids for prophylaxis or treatment of acute GVHD, or development of either acute GVHD or clinically significant microangiopathic hemolytic anemia (MAHA) post-BMT. In multivariate analysis, the most important predictors were the use of VP-16 (p = 0.008), the use of a continuous infusion CSP plus MP prophylactic regimen for GVHD (p = 0.003) and the development of MAHA after BMT (p less than 0.001). The strong association with MAHA suggests that endothelial damage is related to the development of this complication.

[Title]: KCNMB1 genotype influences response to verapamil SR and adverse outcomes in the INternational VErapamil SR/Trandolapril STudy (INVEST).
[Abstract]: OBJECTIVES: We sought to determine whether polymorphisms in the large-conductance calcium and voltage-dependent potassium (BK) channel beta1 subunit gene, KCNMB1, are associated with blood pressure response to verapamil SR or adverse outcomes in the GENEtic substudy of the INternational VErapamil SR/trandolapril STudy (INVEST-GENES). BACKGROUND: KCNMB1 is involved in calcium sensitivity and hypertension. The association between variability in KCNMB1 and calcium antagonist response, however, has not been assessed. METHODS: Genetic samples were collected from 5979 patients in INVEST. Blood pressure response to verapamil SR and time to achieve blood pressure control was assessed in relation to Glu65Lys and Val110Leu genotypes. The primary outcome (all cause mortality, nonfatal myocardial infarction or nonfatal stroke) was compared between genotype groups, and interaction with verapamil SR therapy was assessed. RESULTS: Systolic blood pressure response to verapamil SR did not differ by KCNMB1 genotype. Lys65 variant carriers, however, achieved blood pressure control earlier than Glu65Glu individuals [1.47 (interquartile ratio 2.77) versus 2.83 (interquartile ratio 4.17) months, P=0.01] and were less likely to require multiple drugs at the time of blood pressure control (adjusted odds ratio 0.43, 95% confidence interval 0.19-0.95). Leu110 variant carriers had a reduced risk of primary outcome (hazard ratio 0.68, 95% confidence interval 0.47-0.998). Subgroup analysis revealed this finding to be more pronounced in verapamil SR-assigned patients (hazard ratio 0.587, 95% confidence interval 0.33-1.04) compared with atenolol-assigned patients (hazard ratio 0.946, 95% confidence interval 0.56-1.59). No difference was seen in the occurrence of the primary outcome compared by codon 65 genotype. CONCLUSIONS: Our findings suggest that KCNMB1 genotype influences responsiveness to verapamil SR and risk of adverse cardiovascular outcomes.

[Title]: Pyridoxine and pyridostigmine treatment in vincristine-induced neuropathy.
[Abstract]: Vincristine is a commonly used antineoplastic drug and frequently causes neurotoxicity. Here the authors report a 4-year-old boy with acute lymphoblastic leukemia in whom vincristine-induced peripheral and cranial neuropathy developed during remission induction therapy. The patient seemed to benefit from pyridoxine and pyridostigmine therapy greatly and this therapy is recommended in patients with severe vincristine-induced neuropathy.

[Title]: Adjunctive treatment with a dopamine partial agonist, aripiprazole, for antipsychotic-induced hyperprolactinemia: a placebo-controlled trial.
[Abstract]: OBJECTIVE: Hyperprolactinemia and associated side effects often occur with antipsychotics. The authors investigated the effect of adjunctive treatment with aripiprazole on hyperprolactinemia and psychopathology in patients with schizophrenia maintained with haloperidol. METHOD: Fifty-six patients with hyperprolactinemia taking haloperidol were enrolled. Haloperidol dose was fixed; aripiprazole was dosed at 15 mg/day for the first 4 weeks, then 30 mg/day for the following 4 weeks. Serum prolactin, haloperidol, and aripiprazole levels were measured. Symptoms and side effects were assessed with the Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Negative Symptoms, Clinical Global Impression symptom scale, Simpson-Angus Rating Scale, and Barnes Akathisia Rating Scale at weeks 1, 2, 4, 6, and 8. RESULTS: Prolactin levels of patients receiving aripiprazole significantly decreased over time, demonstrating a significant time effect and a time-by-group interaction. In the aripiprazole group, 88.5% of patients at week 8 had prolactin levels normalize compared to 3.6% of patients receiving placebo. Among 11 female patients with menstrual disturbances randomly assigned to aripiprazole, seven patients regained menstruation during the study, whereas none receiving placebo did. Plasma levels of haloperidol were not significantly altered. No significant time effect and time-by-group interactions on BPRS, Scale for the Assessment of Negative Symptoms, and Simpson-Angus Rating Scale scores were noted. CONCLUSIONS: Adjunctive aripiprazole treatment reversed hyperprolactinemia in both sexes, resulting in reinstatement of menstruation in female patients, with no significant effects on psychopathology and extrapyramidal symptoms. Aripiprazole has higher affinity to dopamine D(2) receptors than haloperidol, which is the likely cause of this observation.

[Title]: Clinical efficacy and tolerability of tenoxicam in African patients with osteoarthritis, rheumatoid arthritis, tendinitis and/or bursitis: an open study.
[Abstract]: An open clinical evaluation was carried out in 736 African out-patients suffering from rheumatic and inflammatory disorders to assess the efficacy and tolerability of tenoxicam in relieving the signs and symptoms of their condition. On entry, all previous treatment was discontinued and patients received a simple daily dose of 20 mg tenoxicam orally for 15 days in the case of those with rheumatoid arthritis or tendinitis, or for 30 days in those with osteoarthritis. Paracetamol was allowed as a rescue analgesic. Subjective verbal scale assessments were used to determine levels of pain at rest, on movement and at night, sleep disturbance and functional incapacity, on entry and during treatment. At the end of the study period, both physicians and patients gave an overall opinion of the clinical response to tenoxicam, and patients were asked how their current compared with their previous treatment. The results showed that approximately 90% of patients had an excellent or good response to tenoxicam with marked improvement in all the signs and symptoms evaluated. Moreover, tenoxicam proved to be well tolerated, only a small number of patients reporting adverse events, mainly gastro-intestinal.

[Title]: A novel compound heterozygous dysferlin mutation in Miyoshi myopathy siblings responding to dantrolene.
[Abstract]: Miyoshi myopathy (MM) is an autosomal recessive distal muscular dystrophy characterized by mutations of the dysferlin gene. Although several pairs of homozygous/heterozygous mutations have been reported, few effective treatments of MM are available. We had observed the decreased serum creatine kinase (CK) before and after administration of dantrolene in the elder brother and the increased serum CK before and after discontinuance of the drug on suspicion of drug-induced hepatopathy in the younger sister. We report a novel pair of heterozygous mutations in the 3'-splicing site of exon 26 and the translation site of exon 28 of the dysferlin gene in two siblings, and effective treatment of their MM with dantrolene.

[Title]: Flavopiridol in the treatment of chronic lymphocytic leukemia.
[Abstract]: PURPOSE OF REVIEW: The synthetic flavone flavopiridol induces apoptosis of chronic lymphocytic leukemia cells in vitro; however, initial studies administering flavopiridol by a 24- to 72-h continuous intravenous infusion demonstrated no clinical activity. This review focuses on a novel dosing regimen that has achieved significant clinical activity in relapsed, poor-risk chronic lymphocytic leukemia. RECENT FINDINGS: Binding to human plasma proteins reduces free flavopiridol concentration and makes continuous intravenous infusion dosing ineffective. Pharmacokinetic modeling indicated that administering flavopiridol by a 30-min intravenous bolus followed by a 4-h continuous intravenous infusion would achieve serum concentrations necessary to induce in-vivo apoptosis. Our institution conducted a phase I study in relapsed chronic lymphocytic leukemia. Dose-limiting toxicity was acute tumor lysis syndrome resulting in fatal hyperkalemia. Careful monitoring and aggressive intervention for hyperkalemia, including hemodialysis if necessary, allowed flavopiridol to be given safely. Nineteen of 42 patients responded (45%), including five of 12 patients (42%) with del(17p13) and 13 of 18 patients (72%) with del(11q22). SUMMARY: Flavopiridol, when administered by a 30-min intravenous bolus followed by a 4-h continuous intravenous infusion, is active in high-risk, refractory chronic lymphocytic leukemia. Careful monitoring and aggressive intervention for tumor lysis syndrome and hyperkalemia is necessary for safe drug administration. Further studies to optimize the dose and schedule of administration, and to study this drug in other hematologic malignancies, are ongoing.

[Title]: Prevalence of alpha-1 antitrypsin deficiency in poorly controlled asthma--results from the ALA-ACRC low-dose theophylline trial.
[Abstract]: In a study comparing low-dose theophylline to montelukast in poorly controlled asthmatics, 285 subjects consented to be screened for alpha-1 antitrypsin deficiency. Of the 284 for which complete data was available, 10.5% carried a deficiency gene and 2.4% were mildly deficient with an alpha-1 antitrypsin serum level of less than 20 mu M. In the non-African-American cohort, an abnormal phenotype occurred in 12% and 2.9% were mildly deficient. Baseline pulmonary function and asthma scores were not significantly different between those with normal and abnormal AAT phenotype. However those with the deficiency tended to show a greater bronchodilator response.
