[Title]: Topiramate in the treatment of obese subjects with drug-naive type 2 diabetes.
[Abstract]: AIM: The aim of this study was to examine the efficacy and safety of topiramate as an adjunct to diet and exercise in drug-naive, obese subjects with type 2 diabetes. METHODS: Drug-naive individuals with type 2 diabetes, body mass index (BMI) of &gt; or =27 and &lt;50 kg/m(2) and haemoglobin A(1c) (HbA(1c)) of &lt;10.5% were enrolled into the study. All the individuals participated in a non-pharmacologic weight loss program (Pathways to Change((R)); Johnson &amp; Johnson Healthcare Systems, Piscataway, NJ, USA) throughout the trial. After a 6-week placebo run-in, the subjects were randomized to placebo, topiramate 96 mg/day or topiramate 192 mg/day. Subjects were scheduled for 8-week titration and 52-week maintenance phases. The study was ended early; efficacy data were reported for a predefined modified intent-to-treat (MITT) population (n = 229), with 40 weeks of treatment. All the subjects who provided any safety data were included in the safety population (n = 535). RESULTS: Baseline mean weight was 103.7 kg, BMI 36 kg/m(2) and HbA(1c) 6.7% across all treatment groups. By the end of week 40, the placebo, the topiramate 96 mg/day and topiramate 192 mg/day groups lost 2.5, 6.6 and 9.1% of their baseline body weight respectively (p &lt; 0.001 vs. placebo, MITT population using last observation carried forward). The decrease in HbA(1c) was 0.2, 0.6 and 0.7% respectively (p &lt; 0.001 vs. placebo, MITT). Topiramate significantly reduced blood pressure and urinary albumin excretion; a weight-loss-independent HbA(1c) improving effect of topiramate was demonstrated. Adverse events were predominantly related to central nervous system (CNS). CONCLUSIONS: Topiramate as an add-on treatment to lifestyle improvements produced significant weight loss and improved glucose homeostasis in obese, drug-naive subjects with type 2 diabetes. These treatment advantages should be balanced against the occurrence of adverse events in the CNS.

[Title]: Effects of nalbuphine on anterior pituitary and adrenal hormones and subjective responses in male cocaine abusers.
[Abstract]: Nalbuphine (Nubain) is a mixed action mu-kappa agonist used clinically for the management of pain. Nalbuphine and other mu-kappa agonists decreased cocaine self-administration in preclinical models. Cocaine stimulates the hypothalamic-pituitary-adrenal (HPA) axis, but the effects of nalbuphine on the HPA axis are unknown. Analgesic doses (5 and 10 mg/70 kg) of IV nalbuphine were administered to healthy male cocaine abusers, and plasma levels of PRL, ACTH and cortisol were measured before and at 10, 17, 19, 23, 27, 31, 35, 40, 45, 60, 75, 105, and 135 min after nalbuphine administration. Subjective effects were measured on a Visual Analog Scale (VAS). Prolactin (PRL) increased significantly within 17 min (P=.04) and reached peak levels of 22.1+/-7.1 ng/ml and 54.1+/-11.3 at 60 min after low and high dose nalbuphine administration, respectively. VAS reports of "Sick," "Bad" and "Dizzy" were significantly higher after 10 mg/70 kg than after 5 mg/70 kg nalbuphine (P=.05-.0001), and were significantly correlated with increases in PRL (P=.05-.0003). However, sedation and emesis were observed only after a 10 mg/70 kg dose of nalbuphine. Interestingly, ACTH and cortisol levels did not change significantly after administration of either dose of nalbuphine. Taken together, these data suggest that nalbuphine had both mu- and kappa-like effects on PRL (PRL increase) but did not increase ACTH and cortisol.

[Title]: Polymorphisms in folate, pyrimidine, and purine metabolism are associated with efficacy and toxicity of methotrexate in psoriasis.
[Abstract]: Methotrexate is the gold standard therapy for moderate to severe psoriasis, but there is marked interpersonal variation in its efficacy and toxicity. We hypothesized that in psoriasis patients, specific common polymorphisms in folate, pyrimidine, and purine metabolic enzymes are associated with methotrexate efficacy and/or toxicity. DNA from 203 retrospectively recruited psoriasis patients treated with methotrexate was collected and genotyped by restriction endonuclease digestion or length polymorphism assays. The reduced folate carrier (RFC) 80A allele and the thymidylate synthase (TS) 3'-untranslated region (3'-UTR) 6 bp deletion were associated with methotrexate-induced toxicity (P=0.025 and P=0.025, respectively). RFC 80A and 5-aminoimidazole-4-carboxamide ribonucleotide transformylase (ATIC) 347G were associated with methotrexate discontinuation (P=0.048 and P=0.038). The TS 5'-UTR 28 bp 3R polymorphism correlated with poor clinical outcome (P=0.029), however, this was not the case when patients with palmoplantar pustular psoriasis were not included in the analysis. Stronger associations between specific polymorphisms and methotrexate-induced toxicity and discontinuation were found in a subanalysis of patients on methotrexate not receiving folic acid supplementation. We have demonstrated preliminary evidence that specific polymorphisms of enzymes involved in folate, pyrimidine, and purine metabolism could be useful in predicting clinical response to methotrexate in patients with psoriasis.

[Title]: [The influence of CYP2C9 genetic polymorphism on the pharmacokinetics and pharmacodynamics of warfarin in patients with constant atrial fibrillation].
[Abstract]: CYP2C9 is the main enzyme participating in warfarin metabolism, of which genetic polymorphism is typical. The aim of the study was to investigate the influence of having allelic variants CYP2C9*2 and CYP2C9*3 on the pharmacokinetics, dosage regimen, and the rate of hemorrhage in patients with constant atrial fibrillation taking warfarin. Eighty-two patients with constant atrial fibrillation taking warfarin were included in the study. It was shown that in patients with CYP2C9*2 and CYP2C9*3 the clearance of warfarin and its dose were lower, while the episodes of excessive hypocoagulation and hemorrhage associated with warfarin were more frequent than in patients without these allelic variants. Basing on the results of the study, the authors propose an algorithm of choosing the initial warfarin dose depending on CYP2C9 genotype.

[Title]: Ameliorating effect of coenzyme Q10, riboflavin and niacin in tamoxifen-treated postmenopausal breast cancer patients with special reference to lipids and lipoproteins.
[Abstract]: OBJECTIVES: Tamoxifen (TAM), a non-steroidal anti-estrogen that is widely used in adjuvant therapy for all stages of breast carcinomas and in chemoprevention of high-risk group. The hepatic estrogenic effect of TAM induces hypertriglyceridemia by reduced activity of lipolytic enzymes (LPL) on triglycerides. Coenzyme Q10 (Co Q10), riboflavin and niacin are proved to be potent antioxidant and protective agents against many diseases including cancer and cardiovascular diseases (CVD). In this context, the objective of the study is to find the effect of the combined modality of Co Q10 (100 mg), riboflavin (10 mg) and niacin (50 mg) with TAM (10 mg twice a day) on serum lipids and lipoprotein levels in postmenopausal women with breast cancer. DESIGN AND METHODS: The vitamin supplementation with tamoxifen was given for a period of 90 days. Blood samples were collected at the base line, 45th and 90th day during the course of treatment. Plasma total cholesterol (TC), free cholesterol (FC), ester cholesterol (EC), phospholipids (PL), triglycerides (TGL), free fatty acids (FFA), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very low density cholesterol (VLDL-C) were estimated in 78 untreated, only TAM-treated and combinatorialy treated group along with 46 age- and sex-matched controls. RESULTS: Serum TGL and VLDL-C (p&lt;0.001) were found to be significantly elevated and LDL-C (p&lt;0.01), significantly reduced among TAM-treated patients as compared to the untreated breast cancer subjects. All the lipids and lipoprotein levels were found to be significantly altered in the untreated breast cancer patients when compared to their normal counterparts. All the lipid and lipoprotein abnormalities were reverted back to near normal levels on 90 days of treatment on combinatorial therapy. CONCLUSION: The study figures the altered lipid and lipoprotein levels in the untreated and TAM-treated breast cancer patients. On combination therapy with Co Q10, riboflavin and niacin, it counteracts the tamoxifen-induced hyperlipidemia to normal levels.

[Title]: Modified Irinotecan/5FU/Leucovorin therapy in advanced colorectal cancer and predicting therapeutic efficacy by expression of tumor-related enzymes.
[Abstract]: OBJECTIVE: To evaluate the efficacy and safety of a regimen using Irinotecan, 5FU and Leucovorin for patients with advanced or recurrent colorectal cancer. MATERIAL AND METHODS: Irinotecan (75 mg/m(2)) was administered biweekly, while 5FU (600 mg/m(2)) and Leucovorin (250 mg/m(2)) were administered weekly, for 6 weeks. RESULTS: The 21 consecutive patients subjected to this regimen showed a good response rate (43%) with minimal toxicity (incidence of grade 3/4: leukopenia and neutropenia, 5%, respectively, and vomiting, 10%). The mean survival time of all 21 patients was 15.7 months. This regimen could be a valid option for patients with advanced colorectal cancer, especially those seeking a good QoL (quality of life) for the remainder of their lives. We evaluated the expression of thymidylate synthase (TS), dihydropyrimidine dehydrogenase (DPD), thymidine phosphorylase (TP) and orotate phosphoribosyl transferase (OPRT) mRNAs, and sialyl Lewis X on formalin-fixed, paraffin-embedded colorectal tumor samples. Expression of TS mRNA or sialyl Lewis X was negatively correlated with the response from chemotherapy. Patients with low DPD mRNA expression in the tumor showed a significant longer survival than those with high expression. In patients with high TP mRNA expression, there was a tendency towards a high incidence of leukopenia. CONCLUSIONS: Some predictive factors elucidated in this study could contribute to the progress of the tumor-biology based, individualized chemotherapy for colorectal cancer patients.

[Title]: Role of intravenously administered hyoscine butyl bromide in retrograde terminal ileoscopy: a randomized, double-blinded, placebo-controlled trial.
[Abstract]: AIM: To evaluated the role of hyoscine butyl bromide in facilitating retrograde ileoscopy. METHODS: Retrograde terminal ileoscopy was attempted in 200 consecutive patients undergoing colonoscopy. After intubation of the cecum and visualization of the ileocecal valve, butyl bromide injection or normal saline was given intravenously to the patients in a double blind random fashion. The pulse rate and oxygen saturation were measured continuously. After completion of the procedure, endoscopists were then asked to score the ease of intubation and the ease of visualization of the terminal ileum on a visual scale of 1 to 10. The patients were also asked to score the pain after receiving hyoscine butyl bromide injection on a score of 1 to 10. RESULTS: Terminal ileoscopy could be performed in 188 patients. The mean (SD) visual analogue score for the ease of intubation of the cecum was 7.4 (0.65) in the injection group and 5.9 (0.8) in the placebo group (P &lt; 0.001). The mean (SD) length of ileum visualized in the injection group was 14.4 (3.3) cm and 10.4 (2.7) cm in the placebo group (P &lt; 0.001). The mean (SD) visual analogue score for ease of visualization of the terminal ileum was 7.5 (0.69) in the injection group and 5.9 (0.7) in the placebo group (P &lt; 0.001). The pain score experienced by the patients was 6.5 (0.7) in the injection group and 6.7 (0.69) in the placebo group (P &lt; 0.008). Although the pulse rate increased significantly in patients receiving the drug, no statistically significant difference was noted in the oxygen saturation between the two groups either before or after administration of the drug. No complications were observed in either of the groups. CONCLUSION: Hyoscine butyl bromide injection is a useful adjunct in helping the intubation and visualization of terminal ileum during colonoscopy.

[Title]: Determinants of liver damage associated with intravenous methylprednisolone pulse therapy in Graves' ophthalmopathy.
[Abstract]: BACKGROUND: Intravenous methylprednisolone pulses (IVMP) are more efficacious and better tolerated than oral prednisone in Graves' ophthalmopathy (GO) patients. However, acute and severe liver damage has been reported in sporadic cases during IVMP, resulting in fatal acute liver failure in four patients so far. The mechanism causing the liver damage is incompletely understood. DESIGN: We performed a prospective observational study in 13 patients with dysthyroid optic neuropathy (group A) and in 14 patients with moderately severe GO (group B) who were treated with high-dose (group A) or low-dose (group B) IVMP; cumulative steroid doses were 8.45 g in group A and 4.5 g in group B, and follow-up time was 24 weeks. MAIN OUTCOME: Slight increases in serum aminotransferases (in alanine aminotransferase [ALAT] more than in aspartate aminotransferase [ASAT]) were observed, in seven patients exceeding the upper normal limit of 40 U/L. These changes were more prominent in group A than in group B as was also evident from a decrease in ASAT/ALAT ratio in group A but not in group B. Changes in serum aminotransferases occurred especially in the first 6 weeks of IVMP, becoming smaller thereafter with the decrease in steroid dosage. Pretreatment liver steatosis or diabetes were not related to liver damage, but preexistent viral hepatitis was. CONCLUSION: IVMP in GO patients causes dose-dependent liver damage by a direct toxic effect of glucocorticoids on hepatocytes. Nevertheless, IVMP seems to be pretty safe if cumulative doses exceeding 8 g are avoided and liver function is checked before and at regular intervals during pulse therapy.

[Title]: Renoprotection of Optimal Antiproteinuric Doses (ROAD) Study: a randomized controlled study of benazepril and losartan in chronic renal insufficiency.
[Abstract]: The Renoprotection of Optimal Antiproteinuric Doses (ROAD) study was performed to determine whether titration of benazepril or losartan to optimal antiproteinuric doses would safely improve the renal outcome in chronic renal insufficiency. A total of 360 patients who did not have diabetes and had proteinuria and chronic renal insufficiency were randomly assigned to four groups. Patients received open-label treatment with a conventional dosage of benazepril (10 mg/d), individual uptitration of benazepril (median 20 mg/d; range 10 to 40), a conventional dosage of losartan (50 mg/d), or individual uptitration of losartan (median 100 mg/d; range 50 to 200). Uptitration was performed to optimal antiproteinuric and tolerated dosages, and then these dosages were maintained. Median follow-up was 3.7 yr. The primary end point was time to the composite of a doubling of the serum creatinine, ESRD, or death. Secondary end points included changes in the level of proteinuria and the rate of progression of renal disease. Compared with the conventional dosages, optimal antiproteinuric dosages of benazepril and losartan that were achieved through uptitration were associated with a 51 and 53% reduction in the risk for the primary end point (P = 0.028 and 0.022, respectively). Optimal antiproteinuric dosages of benazepril and losartan, at comparable BP control, achieved a greater reduction in both proteinuria and the rate of decline in renal function compared with their conventional dosages. There was no significant difference for the overall incidence of major adverse events between groups that were given conventional and optimal dosages in both arms. It is concluded that uptitration of benazepril or losartan against proteinuria conferred further benefit on renal outcome in patients who did not have diabetes and had proteinuria and renal insufficiency.
