[Title]: Beta-adrenoceptor genotype influences the response to carvedilol in patients with congestive heart failure.
[Abstract]: Although the widespread introduction of beta-adrenoceptor antagonists into the management of congestive heart failure (CHF) has led to significant improvements in morbidity and mortality, it is also apparent that clinical responses to this therapy vary substantially. With the recognition that functionally significant genetic polymorphisms of the beta2-adrenoceptor exist with clinically relevant allelic frequency, we hypothesized that beta2-adrenoceptor genotype may affect the response to carvedilol. The clinical response, influence on left ventricular function and beta2-adrenoceptor (beta2AR) genotype was determined in 80 patients treated with carvedilol. A clinically significant improvement in left ventricular function (good responder) was defined as an absolute improvement of 10% in the left ventricular ejection fraction or 5% in the fractional shortening. Consistent with studies performed in vitro on the influence of beta2AR genotype and receptor desensitization, subjects who were homozygous for the allele encoding the Gln27 polymorphism displayed a significantly lower proportion of good responders than patients who were homozygous or heterozygous for the Glu27 polymorphism (26% versus 63%, P=0.003). These data demonstrate a significant influence of beta2AR genotype in the response to carvedilol in CHF patients. Accordingly, determination of beta2AR status may be of value in the tailoring of individual therapy in patients with CHF.

[Title]: Reversal of central benzodiazepine effects by flumazenil after conscious sedation produced by intravenous diazepam. The Flumazenil in Intravenous Conscious Sedation with Diazepam Multicenter Study Group I.
[Abstract]: Flumazenil is a competitive benzodiazepine antagonist that rapidly reverses the residual effects of benzodiazepines following intravenous conscious sedation. In a double-blind, multicenter study, postoperative patients who had been sedated with intravenous diazepam were randomly allocated to receive intravenous doses of flumazenil (0.4 mg to 1 mg) or placebo. Levels of sedation and psychomotor impairment were evaluated prestudy, at baseline, and at 6 intervals from 5 to 180 minutes posttreatment. A global evaluation of effectiveness was made at the 5-minute assessment, and memory was assessed at the 180-minute assessment. Flumazenil (mean dose: 0.73 mg [7.3 ml]) was significantly more effective than placebo (mean dose: 8.9 ml) in reversing sedation, psychomotor impairment, and amnesia within 5 minutes after the start of administration. At the 5-minute posttreatment assessment, 84% of 102 flumazenil-treated patients (compared with 42% of 52 placebo-treated patients) experienced complete reversal of sedation. Ninety-two percent of 93 flumazenil-treated patients (compared with 41% of 46 placebo-treated patients) had normal psychomotor function. Reversal of amnesia at the 5-minute assessment was achieved in 75% of 101 flumazenil-treated patients and in 20% of 51 placebo-treated patients. Statistically significant differences between flumazenil and placebo were also observed at the 15-minute assessment. Thereafter there were no significant differences between the two treatment groups. Most (70%) flumazenil-treated patients exhibited no recurrence of sedation during the 180-minute assessment period. The most frequent adverse reaction in the flumazenil group was dizziness (6%). There were no serious adverse experiences related to the test drug. Flumazenil provided prompt, controlled reversal of residual effects, especially sedation, in the majority (84%) of patients recovering from intravenous conscious sedation induced by diazepam. For most (70%) of these flumazenil-treated patients, the reversal was maintained throughout the 180-minute assessment.

[Title]: Aminosidine (paromomycin) in the treatment of leishmaniasis imported into the United Kingdom.
[Abstract]: We report 11 patients with leishmaniasis from different endemic areas, treated in the UK with intravenous aminosidine alone or in combination with other drugs. Clinical and parasitological cures were achieved in all 7 patients from the Mediterranean zone who had visceral disease, with one relapse. Two of 4 patients with cutaneous or mucosal disease were cured; the other 2, from Iraq and Iran, did not respond. Toxic effects were high-tone deafness in 2 patients, one of whom had pre-existing renal impairment, and transient, mild elevation of serum creatinine in 3. Aminosidine is an effective, tolerable and relatively non-toxic alternative to existing antileishmanial drugs for the treatment of visceral leishmaniasis. Further studies will be needed to assess its place in cutaneous and mucosal disease.

[Title]: Mirtazapine in L-dopa-induced dyskinesias.
[Abstract]: Mirtazapine is a novel antidepressant with a pharmacologic profile (alpha-2 antagonist, 5HT-(1A) agonist, and 5HT-(2) antagonist) that renders it potentially useful for l-dopa-induced dyskinesias. Drugs with 5HT-(1A) agonistic activity, such as buspirone and tandospirone, have been reported to be effective in reducing l-dopa-induced dyskinesias. Furthermore, 5HT-(2) antagonism may, by reducing substantia nigra pars reticulata hyperactivity, play a role in the improvement of Parkinsonian symptoms and l-dopa-induced dyskinesias, as has been observed with ritanserin, a 5HT-(2) antagonist. Alpha-2 antagonists, such as idazoxan, have recently also been reported to improve l-dopa-induced dyskinesias. The authors investigated the antidyskinetic properties of mirtazapine by designing an open-label study of 20 Parkinsonian patients with l-dopa-induced dyskinesias. Mirtazapine proved to be moderately effective in reducing l-dopa-induced dyskinesias, either alone or in association with amantadine. Mirtazapine may be of use in patients who do not respond or are intolerant to amantadine.

[Title]: Lack of tolerance and physical dependence upon repeated treatment with the novel hypnotic zolpidem.
[Abstract]: Zolpidem is a new, short-acting hypnotic of imidazopyridine structure which binds selectively to a subpopulation of receptors involved in the action of benzodiazepines [omega 1 (BZ1) sites of the gamma-aminobutyric acidA receptors]. The present study investigated whether tolerance and physical dependence develop after repeated treatment with zolpidem as is observed with benzodiazepines. Mice were given zolpidem or the benzodiazepine midazolam (2 x 30 mg/kg, p.o.) for 10 consecutive days. Tolerance to central depressant effects (evaluated by recording spontaneous locomotor activity) and to anticonvulsant effects (measured against pentylenetetrazole-, electroshock- and isoniazid-induced convulsions) was assessed 42 hr after the last administration. A decrease in the latency to isoniazid-induced convulsions was taken as an index of physical dependence and was evaluated 3, 6, 14, 24, 42 and 67 hr after the end of chronic drug treatment. Repeated treatment with midazolam produced tolerance to its sedative and anticonvulsant activities as indicated by shifts of the dose-response curves by a factor of 3 to 5. Fourteen hr after discontinuation of treatment, spontaneous withdrawal was observed and lasted 3 days. When flumazenil was given 3 or 6 hr after the final midazolam injection, precipitated withdrawal was observed. In contrast, after repeated treatment with zolpidem, there was no change in its ability to produce sedative and anticonvulsant effects. Moreover, neither spontaneous nor flumazenil-induced precipitated withdrawal was observed in zolpidem-treated mice.

[Title]: A comparison of netilmicin and tobramycin therapy in patients with renal impairment.
[Abstract]: We evaluated the toxicity and efficacy of netilmicin and tobramycin in 89 older adults with serious bacterial infections and pre-existing renal impairment in a prospective, blinded, randomized trial. Complete resolution or improvement of infection occurred at 34/36 (94%) evaluable sites in netilmicin-treated patients and at 26/31 (84%) evaluable sites in tobramycin-treated patients. 10/44 (23%) netilmicin- and 7/45 (16%) tobramycin-treated patients experienced nephrotoxicity during treatment. The mean serum creatinine level improved significantly at the end of therapy compared to pre-treatment in those patients who did not experience nephrotoxicity in both treatment groups. 5/19 (26%) netilmicin-treated patients and 2/18 (11%) tobramycin-treated patients assessable for ototoxicity experienced decrements in auditory thresholds. Ototoxic netilmicin-treated patients had higher serum netilmicin levels than did non-ototoxic patients. Patients who experienced ototoxicity were not more likely to have experienced nephrotoxicity. The rates of toxicity were not statistically different and were similar to those seen in studies of patients with normal pre-treatment renal function.

[Title]: The effects of sibutramine and orlistat on the ultrasonographic findings, insulin resistance and liver enzyme levels in obese patients with non-alcoholic steatohepatitis.
[Abstract]: OBJECTIVE: Non-alcoholic steatohepatitis (NASH) is frequent in obese subjects and has a relatively benign course; however, it may progress to cirrhosis. Weight loss in these patients may alleviate the findings of NASH. The aim of this study was to investigate the effects of pharmacological anti-obesity therapies on the findings of NASH. SUBJECTS: There were thirteen patients (9 women, 4 men) in sibutramine group and 12 patients (8 women, 4 men) in orlistat group. The mean ages and body-mass indexes of the two groups were 42.5 years, 37.3 kg/m2 and 43.2 years, 36.1 kg/m2, respectively. METHOD: The obese subjects with NASH were given sibutramine or orlistat for six months. Additionally, all patients were given a low caloric diet. Liver enzymes (AST, ALT, GGT and ALP), insulin resistance (analysed by HOMA) and hepatic ultrasound (US) findings were assessed at baseline and after 6 months. RESULTS: Both sibutramine and orlistat significantly reduced body weight (10.2 and 8.4%, respectively), insulin resistance (47 and 40%, respectively), AST (41 and 39%, respectively), ALT (59 and 58%, respectively), and GGT serum levels (27 and 25%, respectively). The ultrasonographic regression in steatosis was observed in 11 patients who received sibutramine and 8 patients who received orlistat. During the treatment, unexpectedly significant increases in total alkaline phosphatase levels were found in both sibutramine and orlistat groups (9 and 14%, respectively). CONCLUSION: The present study shows that both sibutramine-induced and orlistat-induced weight losses result in reduction of insulin resistance, and improvements in biochemical markers and US findings of NASH. Because the GGT levels decreased in both groups, the increased ALP levels might have another source.

[Title]: Long-term efficacy and safety of sildenafil for patients with erectile dysfunction.
[Abstract]: BACKGROUND: To investigate the long-term efficacy and safety of sildenafil for patients with erectile dysfunction (ED). METHODS: Between March 1999 and February 2001, a total of 3168 patients visited Taipei Veterans General Hospital for prescription of sildenafil. The follow-up period was 1-3 years. A questionnaire was designed for evaluation of efficacy and safety of sildenafil via telephone survey. RESULTS: Of the 3168 patients, 1414 were interviewed by telephone. Data from telephone questionnaires were successfully obtained in 1074 cases. Achievement of the first penile erection after sildenafil was reported in 58.8% of our patients. The distribution of the first doses was 0.6%, 8.5%, 81.9% and 90% for 12.5 mg, 25 mg, 50 mg and 100 mg, respectively. After administration of sildenafil, 72.1% men had successful intercourses "sometimes" or "always achieving vaginal penetration", and 72.3% had "slight difficulty" or "no difficulty" in maintaining of sexual intercourses. The "sometimes/most times/always" satisfaction accounted 63.9% and 62.8%, respectively for patients and partners. The global assessment of penile erection was improved in 58.6% of the patients. The sexual confidence of the patients was moderate, high and very high in 72.4% of the patients. Of the 434 patients who failed first penile erections, 400 (92.2%) were related to improper administration of sildenafil. Discontinuation of sildenafil in the last 3 months before telephone survey was found in 852 patients (80.2%). The causes of discontinuation were loss of efficacy in 51.6% of patients, lack of sexual desire in 8.8%, and chronic diseases in 8.2%. Spontaneous erection without sildenafil was claimed in 21.5% of the patients (most times in 9.5% and always in 12.0%). The rate of adverse events after taking sildenafil were 16.6%, and the most common adverse event was facial flushing (9.2%). CONCLUSIONS: The results of this study demonstrated that the efficacy of sildenafil was similar to the previous clinical trials. The adverse events after sildenafil were mild and tolerable. Recovery of complete or partial spontaneous erection was noted in some patients (21.5% in our study) after long-term usage of sildenafil.
