[Title]: Long-term comparative experience with tolcapone and entacapone in advanced Parkinson's disease.
[Abstract]: The objective of this study was to compare the long-term tolerability and efficacy of tolcapone and entacapone in patients with fluctuating Parkinson's disease (PD). Tolcapone and entacapone are two currently available catechol- O -methyltransferase inhibitors that have demonstrated efficacy in the treatment of advanced PD. There are little published data on long-term experience and no direct comparisons. We compared the results of two separate, simultaneous, long-term open label extensions, one for tolcapone and the other for entacapone. The inclusion/exclusion criteria were similar. Data were collected prospectively at 6, 12, 24, and 36 months. Efficacy measures included the Unified Parkinson's Disease Rating Scale (UPDRS) total score, subscores, items 32 (duration of dyskinesia) and 39 (duration of "off" time), and levodopa dose. The two groups were compared using a Mann-Whitney U test for change from baseline and analysis of variance. Tolerability was defined as the ability of patients to maintain therapy and was compared using a Kaplan-Meier analysis. Eleven patients enrolled in the entacapone study and 14 in the tolcapone study. The tolcapone group had more severe disease with significantly higher UPDRS motor score, duration of "off," and levodopa dose requirement. Tolcapone was more effective in lowering UPDRS motor and complication subscores, duration of "off" time, and levodopa doses. UPDRS motor scores and change in levodopa dose in the tolcapone group remained below baseline level for 36 months; however, they were above baseline in the entacapone group from 6 months on. Tolerability was the same for both treatments. Tolcapone appears to have greater and longer efficacy with regard to motor symptoms, "off" time, and change in levodopa requirements than entacapone. These findings indicate that tolcapone continues to have a place in the treatment of advanced PD. However, the risks associated with this drug, particularly hepatic injury, and the requirement for rigorous blood monitoring, need to be considered when choosing an appropriate treatment for patients with advanced PD.

[Title]: Neurologic outcomes of pediatric epileptic patients with pentobarbital coma.
[Abstract]: Status epilepticus is a life-threatening condition requiring emergent medical attention. Although initial therapies with antiepileptic drugs generally terminate seizures within 30 to 60 minutes, patients with refractory status epilepticus require additional intervention. High-dose pentobarbital has been the most commonly prescribed agent for the management of refractory status epilepticus in children. The objective of this research was to evaluate the association between the response of pentobarbital coma and neurologic outcomes in refractory status epilepticus. Twenty-three subjects were treated with pentobarbital coma for at least 48 hours. Medical records were reviewed to collect patient demographic information, responses to treatment, and neurologic outcomes. Among the 23 patients reviewed, 12 patients were controlled with pentobarbital (responders), six were unresponsive to pentobarbital (nonresponders), and five patients relapsed after discontinuation or during tapering of pentobarbital (relapser). The mortality rate among the relapser and nonresponder groups combined was 90.9%, but no deaths occurred among the responder group (P &lt; 0.001). The survival rate was greater among toddlers compared with neonates or older children. Failure of seizure control after pentobarbital coma was associated with a poor prognosis. The potential for serious complications of pentobarbital therapy among neonates highlights the need for careful dosing in this age group.

[Title]: Olanzapine as long-term adjunctive therapy in treatment-resistant bipolar disorder.
[Abstract]: The aim of this study was to estimate the long-term effectiveness of olanzapine as adjunctive therapy in patients with bipolar disorder who exhibited an inadequate response to mood stabilizers. Twenty-three Research Diagnostic Criteria (RDC) patients with bipolar I and II were assessed by means of the Schedule for Affective Disorders and Schizophrenia and entered if they gave their consent to participate. All of them had experienced frequent relapses, residual subsyndromal symptoms, and inadequate responses to other drugs, such as lithium, valproate, or carbamazepine. While maintaining other drugs, they all received open-label, increasing doses of olanzapine, until achieving clinical response. Other drugs were maintained. The patients were assessed several consecutive times from baseline to the endpoint with the Clinical Global Impressions (CGI) scale for use in bipolar illness. Records of recurrences, hospitalizations, and side effects were also collected. The last-observation-carried-forward analysis showed that there was a significant reduction of CGI scores after the introduction of olanzapine, either in manic symptoms (p = 0.0015), depressive symptoms (p = 0.0063), or global symptoms (p = 0.0003). The most frequent adverse events were somnolence (17%) and weight gain (13%). The mean dose of olanzapine at the end of the 43-week follow-up was 8.1 mg/day. Olanzapine may be a useful medication for the long-term adjunctive treatment of patients with bipolar disorder who exhibit a poor response to mood stabilizers, such as lithium, valproate, or carbamazepine. These results suggest mood-stablizing properties of olanzapine.

[Title]: Angiotensin converting enzyme gene polymorphism predicts blood pressure response to angiotensin II receptor type 1 antagonist treatment in hypertensive patients.
[Abstract]: OBJECTIVES: To determine whether polymorphisms in the renin-angiotensin system can predict blood pressure-lowering response to antihypertensive treatment; more specifically, in response to treatment with irbesartan or atenolol. DESIGN AND METHODS: Eighty-six patients with hypertension were randomized to double-blind treatment with either the angiotensin II type 1 receptor antagonist irbesartan or the beta1 adrenergic receptor blocker atenolol and followed for 3 months. We analysed angiotensinogen T174M and M235T, angiotensin converting enzyme (ACE) I/D and angiotensin II type 1 receptor A1166C polymorphisms and related them to blood pressure reduction. RESULTS: The mean reductions in blood pressure were similar for both treatments. In the irbesartan group, individuals homozygous for the ACE gene I allele showed a greater reduction in diastolic blood pressure, exceeding those with the D allele (-18 +/- 11 SD versus -7 +/- 10 mmHg, P = 0.0096). This was not the case during treatment with atenolol, and the interaction term between type of treatment and ACE II genotype was significant (P = 0.0176). The angiotensinogen and angiotensin II type 1 receptor polymorhisms were not related to the response to treatment. CONCLUSIONS: ACE genotyping predicted the blood pressure-lowering response to antihypertensive treatment with irbesartan but not atenolol. Thus, specific genotypes might predict the response to specific antihypertensive treatment.

[Title]: Effects of short-term citicoline treatment on acute cocaine intoxication and cardiovascular effects.
[Abstract]: RATIONALE: The majority of pharmacotherapies proposed for cocaine dependence have been marginally effective and frequently have undesirable side effects. We recently demonstrated that short-term treatment with citicoline decreased self-reported desire to use cocaine in crack cocaine users. OBJECTIVE: The present study was conducted to assess the safety of citicoline in combination with cocaine by investigating whether cocaine-induced cardiovascular and behavioral effects and cocaine plasma levels are altered by citicoline pretreatment. METHODS: Eight healthy male and female volunteers who used cocaine on an occasional basis participated in this randomized, placebo-controlled, three-visit study. During all three visits, subjects received an acute intranasal dose of cocaine (0.9 mg/kg) and were continuously monitored for the ensuing 3.5 h. The first visit involved no pretreatment, and visits 2 and 3 were preceded by a 4-day pretreatment period of either citicoline (1 g/day) or placebo. RESULTS: Citicoline pretreatment did not alter the cardiovascular, physiologic, or subjective effects of acute cocaine. CONCLUSIONS: Although citicoline did not block the acute subjective effects of cocaine in a laboratory environment, the combined use of citicoline and a moderate dose of intranasal cocaine presented no added risk of cardiovascular effects. Further study is necessary to determine whether this medication (which is currently used to treat strokes) will be a useful adjunct to treat cocaine dependence.

[Title]: Lamivudine treatment for hepatitis B reactivation in HBsAg carriers after organ transplantation: a 4-year experience.
[Abstract]: BACKGROUND: Reactivation of hepatitis B after organ transplantation in hepatitis B surface antigen (HBsAg) carriers may be fatal. In this study, we reported our experience of lamivudine treatment in HBsAg carriers who had post-transplant reactivation of hepatitis B. METHODS: The patients were 15 men and one woman. Nine received kidney transplants, six received heart transplants, and one received a lung transplant. They developed a reactivation of hepatitis B 1-101 months (median, 14 months) after transplantation. They received lamivudine 100 mg daily on a compassionate-use basis, and had regular follow ups. The median pretreatment total serum bilirubin level was 3.0 mg/dL, and the alanine aminotransferase level was 357 U/L. Four of the 16 patients were positive for HBeAg. The serum hepatitis B virus (HBV) DNA levels were &gt; 3000 pg/mL in 13 (81%) patients. Three were coinfected with hepatitis C virus. RESULTS: The overall survival rate was 75%. All four fatal cases had a pretreatment total serum bilirubin level of &gt; or = 3 mg/dL. Serum HBV-DNA soon became undetectable in 12 survivors. Of the 12 survivors, after a median treatment period of 101 weeks, a lamivudine-resistant strain with variation in the YMDD motif of the HBV polymerase gene developed in three (25%). None had significant adverse reactions to lamivudine treatment. CONCLUSIONS: These results indicated that lamivudine is effective in the treatment of post-transplant hepatitis B reactivation, including patients with dual chronic hepatitis B and C. Early recognition of HBV reactivation and prompt lamivudine treatment are important to prevent mortality.

[Title]: Minoxidil in severe hypertension: value when conventional drugs have failed.
[Abstract]: Twenty-six patients were selected for treatment with minoxidil on the basis of hypertension which could not be controlled either because of (1) drug failures and/or (2) side effects of drugs. Sixteen out of the 26 had had one or more previous episodes of malignant hypertension. Reduced renal function was present in the majority; eight patients were on dialysis. Average preminoxidil blood pressure was 202/127 mm. Hg supine and 162/106 upright which fell to 154/87 supine and 143/86 upright after minoxidil. Propranolol or methyldopa was given to control the reflex increase in heart rate. Edema and congestive heart failure refractory to large doses of potent diuretics necessitated discontinuation of the drug in two patients. Minoxidil proved highly efficacious regardless of initial level of blood pressure, etiology, or supine or upright posture.

[Title]: Improvement in blood pressure, arterial stiffness and wave reflections with a very-low-dose perindopril/indapamide combination in hypertensive patient: a comparison with atenolol.
[Abstract]: International guidelines recommend that antihypertensive drug therapy should normalize not only diastolic (DBP) but also systolic blood pressure (SBP). Therapeutic trials based on cardiovascular mortality have recently shown that SBP reduction requires normalization of both large artery stiffness and wave reflections. The aim of the present study was to compare the antihypertensive effects of the very-low-dose combination indapamide (0.625 mg) and perindopril (2 mg) (Per/Ind) with the beta-blocking agent atenolol (50 mg) to determine whether Per/Ind decreases SBP and pulse pressure (PP) more than does atenolol and, if so, whether this decrease is predominantly due to reduction of aortic pulse wave velocity (PWV) (automatic measurements) and reduction of wave reflections (pulse wave analysis, applanation tonometry). In a double-blind randomized study, 471 patients with essential hypertension were followed for 12 months. For the same DBP reduction, Per/Ind decreased brachial SBP (-6.02 mm Hg; 95% confidence interval, -8.90 to -3.14) and PP (-5.57; 95% confidence interval, -7.70 to -3.44) significantly more than did atenolol. This difference was significantly more pronounced for the carotid artery than for the brachial artery. Whereas the 2 antihypertensive agents decreased PWV to a similar degree, only Per/Ind significantly attenuated carotid wave reflections, resulting in a selective decrease in SBP and PP. The very-low-dose combination Per/Ind normalizes SBP, PP, and arterial function to a significantly larger extent than does atenolol, a hemodynamic profile that is known to improve survival in hypertensive populations with high cardiovascular risk.

[Title]: A prospective open-label treatment trial of olanzapine monotherapy in children and adolescents with bipolar disorder.
[Abstract]: OBJECTIVE: The goal of this study was to assess the effectiveness and tolerability of olanzapine in the treatment of acute mania in children and adolescents. METHODS: This was an 8-week, open-label, prospective study of olanzapine monotherapy (dose range 2.5-20 mg/day) involving 23 bipolar youths (manic, mixed, or hypomanic; 5-14 years old). Weekly assessments were made using the Young Mania Rating Scale (YMRS), Clinical Global Impressions Severity Scale (CGI-S), Brief Psychiatric Rating Scale, and Children's Depression Rating Scale. Adverse events were assessed through self-reports, vital sign and weight monitoring, laboratory analytes, and extrapyramidal symptom rating scales (Barnes Akathisia Scale, Simpson-Angus Scale, and Abnormal Involuntary Movement Scale). RESULTS: Twenty-two of the 23 youths (96%) completed the study. Olanzapine treatment was associated with significant improvement in mean YMRS score (-19.0 +/- 9.2, p &lt; 0.001). Using predefined criteria for improvement of &gt; or = 30% decline in the YMRS and a CGI-S Mania score of &lt; or = 3 at endpoint, the overall response rate was 61%. Overall, olanzapine was well tolerated, and extrapyramidal symptom measures were not significantly different from baseline. Body weight increased significantly over the study (5.0 +/- 2.3 kg, p &lt; 0.001). CONCLUSIONS: Open-label olanzapine treatment was efficacious and well tolerated in the treatment of acute mania in youths with bipolar disorder. Future placebo-controlled, double-blind studies are warranted.
