The efficacy and safety of a new enteric-coated formulation of fluoxetine given once weekly during the continuation treatment of major depressive disorder.

BACKGROUND: A simple, once-weekly dosing regimen could be a convenient alternative for many patients during long-term treatment of depression. Such a strategy might also be effective for improving medication compliance and the outcome of continuation treatment. The safety and effectiveness of a new formulation of enteric-coated fluoxetine (90 mg) given once weekly was tested during the continuation treatment of major depressive disorder. METHOD: Patients meeting DSM-IV criteria for major depressive disorder with modified 17-item Hamilton Rating Scale for Depression (HAM-D-17) scores > or = 18 and Clinical Global Impressions-Severity of Illness scale (CGI-S) scores > or = 4 were treated 13 weeks with open-label 20 mg/day of fluoxetine in a multicenter U.S. study. Responders (N = 501) were randomly assigned to receive 20 mg of fluoxetine daily, placebo, or 90 mg of enteric-coated fluoxetine weekly for 25 weeks of double-blind continuation treatment. The primary efficacy measure was the percentage of patients who relapsed. Time to relapse was tested over the 25-week continuation period using log-rank analyses of the Kaplan-Meier estimates of relapse rates. Additional analyses of efficacy included comparison of change from baseline to endpoint for the HAM-D-17, CGI-S, and HAM-D-28 subscales by last observation carried forward (LOCF). Safety measures included comparison of treatment-emergent adverse events, both spontaneous and solicited (using the Association for Methodology of Documentation in Psychiatry-Module 5), vital signs, and laboratory measures. RESULTS: Relapse rates for patients assigned to fluoxetine, either 20 mg daily or 90 mg weekly, were significantly lower than for placebo by log-rank analysis and LOCF analyses of secondary efficacy measures. Efficacy did not significantly differ between the 2 active drug groups by these measures. Enteric-coated fluoxetine at a once-weekly dose of 90 mg was well tolerated, and its safety profile was similar to that of daily 20 mg of fluoxetine. CONCLUSION: The formulation of enteric-coated fluoxetine taken once weekly is effective, safe, and well tolerated for continuation treatment of depression in patients who responded to acute treatment with 20 mg/day of fluoxetine. Monitoring during long-term treatment for evidence of sustained remission is important regardless of dosing regimen.

Fluoxetine versus sertraline and paroxetine in major depressive disorder: changes in weight with long-term treatment.

BACKGROUND: The effects of extended selective serotonin reuptake inhibitor (SSRI) treatment on weight are not well characterized. Also unknown is whether different agents have differential effects. To examine these questions, we assessed weight changes in patients randomly assigned to long-term treatment with fluoxetine, sertraline, or paroxetine. METHOD: Patients (N = 284) with major depressive disorder (DSM-IV) were randomly assigned to double-blind treatment with fluoxetine (N = 92), sertraline, (N = 96), or paroxetine (N = 96) for a total of 26 to 32 weeks. The mean percent change in weight was compared for each group, as was the number of patients who had > or = 7% weight increase from baseline. RESULTS: Patients (fluoxetine, N = 44; sertraline, N = 48; paroxetine, N = 47) who completed the trial were included in these analyses. Paroxetine-treated patients experienced a significant weight increase, fluoxetine-treated patients had a modest but nonsignificant weight decrease, and patients treated with sertraline had a modest but nonsignificant weight increase. The number of patients whose weight increased > 7% from baseline was significantly greater for paroxetine-treated compared with either fluoxetine-treated or sertraline-treated patients. CONCLUSION: Risk of weight gain during extended SSRI treatment differs depending on which SSRI is used.

New approaches to the treatment of refractory depression.

Although the majority of patients with depression respond well to their initial pharmacologic treatment, as many as 30% to 45% fail to achieve an adequate response. In addition to the more traditional lithium and thyroid hormone augmentation strategies, a number of new pharmacotherapeutic approaches are currently being used to help manage refractory depression, including the addition of another agent or a switch to another antidepressant. Augmentation and switching strategies are often selected in order to obtain a different neurochemical effect (e.g., adding a relatively noradrenergic agent to a relatively serotonergic antidepressant). In particular, several studies have suggested that depressed patients refractory to treatment with selective serotonin reuptake inhibitors (SSRIs) may show a good response to newer agents that have a pharmacologic profile distinct from the SSRIs. Furthermore, preliminary studies have shown that the addition of SSRIs to either noradrenergic drugs such as the tricyclic antidepressants (TCAs) or dopaminergic agents may be efficacious, even though concerns about drug-drug interactions and tricyclic cardiac toxicity have limited the use of TCA-SSRI combinations. The introduction of reboxetine, a relatively selective norepinephrine reuptake inhibitor, may increase the use of the latter therapeutic approach because of its improved safety profile compared with the TCAs. The review of treatment options for refractory depression that follows will outline the advantages, disadvantages, and level of support for a number of new treatment strategies.

Management of nonresponse and intolerance: switching strategies.

Approximately 29% to 46% of depressed patients show only partial or no response to treatment with antidepressants, with intolerance a frequent cause of treatment failure or discontinuation. Clinicians frequently switch to other antidepressants patients who have failed to tolerate or to respond to antidepressant treatment. The switching strategy involves substitution of another agent for the agent that has either caused intolerable side effects or has failed to induce a response. Fredman and colleagues have recently surveyed 402 psychiatrists from various parts of the country and asked them what steps they would take for patients who fail to respond to 8 weeks or more of an adequate dose of a selective serotonin reuptake inhibitor (SSRI). Interestingly, switching to a non-SSRI agent was the most popular choice indicated by psychiatrists (44% of respondents), with dual-acting agents and bupropion being the next most commonly chosen agents. Even though there are no controlled trials of switching strategies in the literature to date, clinicians often choose this course of action. This article will review some of the currently available studies on switching strategies.

Weight gain and antidepressants.

Weight gain during antidepressant treatment can be either a sign of improvement in patients who have weight loss as a symptom of depression or a residual symptom in patients who overeat when depressed. However, significant weight gain during the acute phase of treatment or weight gain that continues despite achieving full remission of depressive symptoms is likely to be a side effect of antidepressant treatment. Weight gain is a relatively common problem during both acute and long-term treatment with antidepressants, and it is an important contributing factor to noncompliance. This article will review the literature with regard to the relative risk for weight gain of antidepressants. It appears that tricyclic antidepressants (TCAs) and perhaps monoamine oxidase inhibitors (MAOIs) may be more likely to cause weight gain than the selective serotonin reuptake inhibitors (SSRIs) or the newer antidepressants, with the exception of mirtazapine, which may be placed between the SSRIs and the TCAs in terms of relative risk for weight gain. Paroxetine may be more likely to cause weight gain than the other SSRIs during long-term treatment, and bupropion and nefazodone may be less likely to cause weight gain than the SSRIs in the long term, although more studies are necessary to confirm these impressions.

Patterns of axis I comorbidity in early-onset versus late-onset major depressive disorder.

BACKGROUND: This study of a large clinical sample of depressed patients examined whether childhood onset as compared with adult onset Major Depressive Disorder (MDD) would confer a greater risk for Axis I comorbidity and whether childhood onset MDD would also differ from adult onset MDD in the pattern of comorbid disorders. METHODS: We examined lifetime co-occurrence of Axis I disorders among 381 adult outpatients with MDD by Structured Clinical Interview for DSM-III-R-Patient Edition (SCID-P). Subjects were divided into childhood onset (n = 47), adolescent onset (n = 101) and adult onset (n = 233) MDD groups. RESULTS: We found that the two early-onset groups exhibited significantly increased rates of Axis I comorbidity. The childhood onset group accounted for a disproportionately high percentage of depressed adults with two or more comorbid Axis I disorders. Social and simple phobias and alcohol abuse/dependence were significantly more prevalent among individuals with childhood onset MDD than among individuals with adult onset MDD. Alcohol abuse/dependence, but not anxiety disorders, was significantly more prevalent among adolescent onset than adult onset MDD groups. Panic, generalized anxiety, obsessive-compulsive and somatoform disorders were equally distributed across MDD onset groups. Comorbid disorders were much more likely to have followed onset of MDD among individuals with childhood compared with adult onset, except for social phobia which more frequently preceded the depression. The relative ordering among the comorbid conditions with respect to whether they followed or preceded MDD did not vary notably across the three age of onset groups. CONCLUSIONS: We conclude that early-onset MDD is associated with an increased density of Axis I comorbidity that seems to be limited to specific disorders.

Dysfunctional attitudes and poor problem solving skills predict hopelessness in major depression.

BACKGROUND: Hopelessness is a significant predictor of suicidality, but not all depressed patients feel hopeless. If clinicians can predict hopelessness, they may be able to identify those patients at risk of suicide and focus interventions on factors associated with hopelessness. In this study, we examined potential predictors of hopelessness in a sample of depressed outpatients. METHODS: In this study, we examined potential demographic, diagnostic, and symptom predictors of hopelessness in a sample of 138 medication-free outpatients (73 women and 65 men) with a primary diagnosis of major depression. The significance of predictors was evaluated in both simple and multiple regression analyses. RESULTS: Consistent with previous studies, we found no significant associations between demographic and diagnostic variables and greater hopelessness. Hopelessness was significantly associated with greater depression severity, poor problem solving abilities as assessed by the Problem Solving Inventory, and each of two measures of dysfunctional cognitions (the Dysfunctional Attitudes Scale and the Cognitions Questionnaire). In a stepwise multiple regression equation, however, only dysfunctional cognitions and poor problem solving offered non-redundant prediction of hopelessness scores, and accounted for 20% of the variance in these scores. LIMITATIONS: This study is based on depressed patients entering into an outpatient treatment protocol. All analyses were correlational in nature, and no causal links can be concluded. CONCLUSIONS: Our findings, identifying clinical correlates of hopelessness, provide clinicians with potential additional targets for assessment and treatment of suicidal risk. In particular, clinical attention to dysfunctional attitudes and problem solving skills may be important for further reduction of hopelessness and perhaps suicidal risk.

The prevalence of sleep-related eating disorder in psychiatric and non-psychiatric populations.

BACKGROUND: Sleep-related eating disorder is a little-described syndrome combining features of sleep disorders and eating disorders. The behaviour consists of partial arousals from sleep followed by rapid ingestion of food, commonly with at least partial amnesia for the episode the following day. The aim of this study was to provide an estimate of the prevalence of sleep-related eating disorder. METHODS: The Inventory of Nocturnal Eating, a self-report questionnaire addressing nocturnal eating and sleep disturbance, was administered to out-patients (N = 126) and in-patients (N = 24) with eating disorders, obese subjects (N = 126) in a trial of an anorexic agent, depressed subjects (N = 207) in an antidepressant trial, and an unselected group (N = 217) of college students. Sleep-related eating disorder was operationally defined as nocturnal eating with a self-reported reduced level of awareness, occurring at least once per week. RESULTS: Almost 5.0% (33/700) of the sample described symptoms consistent with sleep-related eating disorder. The in-patient eating disorders group had nearly twice the prevalence (16.7%) of the out-patient eating disorder sample (8.7%), which had nearly twice the prevalence of the next highest group, the student sample (4.6%). Subjects with sleep-related eating disorder endorsed more symptoms consistent with sleep disorders and had higher levels of depression and dissociation than those without nocturnal eating. CONCLUSIONS: Sleep-related eating disorder is more common than is generally recognized, especially in those with a daytime eating disorder. Sleep disorder symptoms are often associated with sleep-related eating disorder, as are depression and dissociation. Evaluation of individuals with eating disorders should include assessment for sleep-related eating.

Open study of the catechol-O-methyltransferase inhibitor tolcapone in major depressive disorder.

Tolcapone is a catechol-O-methyltransferase (COMT) inhibitor that has shown efficacy in the treatment of Parkinson's disease. The authors undertook the first study on the efficacy of this COMT inhibitor in the treatment of major depressive disorder (MDD). The authors also wanted to assess the effects of tolcapone on the choline and myoinositol resonances in the left caudate and dorsolateral frontal lobe through proton magnetic resonance spectroscopy and on whole blood levels of S-adenosyl-L-methionine (SAMe). The study enrolled 21 adults (10 men and 11 women; mean age, 42.6 +/- 9.6 years) with MDD, which was diagnosed using the Structured Clinical Interview for DSM-IV, and an initial score of > or = 16 on the 17-item Hamilton Rating Scale for Depression (HAM-D-17). Patients were then treated openly for 8 weeks with tolcapone 400 mg twice daily. Treatment efficacy was assessed with the HAM-D-17, the Clinical Global Impressions Severity (CGI-S) scale, and the Beck Depression Inventory (BDI). Among all subjects (N = 21), there were significant (p < .0001) decreases at endpoint in HAM-D-17 scores (from 19.4 +/- 2.9 to 10.7 +/- 5.5), CGI-S scores (from 3.9 +/- 0.6 to 2.4 +/- 1.1), and BDI scores (from 21.6 +/- 8.1 to 12.3 +/- 8.6). Eight patients (38%) dropped out before completing the 8-week open study because of diarrhea, elevated liver function tests, increased anxiety, and noncompliance. No significant effects were noted on choline and myoinositol resonance or on SAMe levels in whole blood before and after 2 weeks of tolcapone treatment. The preliminary results suggest that tolcapone may be a promising agent in the treatment of MDD. Furthermore, double-blind, placebo-controlled studies are necessary to confirm this impression.

Compounds containing cytosolic choline in the basal ganglia: a potential biological marker of true drug response to fluoxetine.

OBJECTIVE: Studies have identified two types of antidepressant response: true drug response and placebo pattern response. This study examined the relationship between true drug response and choline-creatine ratios in the basal ganglia of depressed patients treated with fluoxetine. METHOD: The authors evaluated drug-free outpatients with major depression before (N = 41) and after (N = 15) 8 weeks of fluoxetine treatment, 20 mg/day, by using proton magnetic resonance spectroscopy. RESULTS: There was a significant difference in the degree of change from baseline to week 8 in choline-creatine ratios between the true drug response group (N = 8) and the placebo pattern response/nonresponse group (N = 7); the true drug response patients had a 20% increase in choline-creatine ratios, and the placebo pattern response/nonresponse patients had a 12% decrease in choline-creatine ratios. CONCLUSIONS: These data suggest that true drug response to fluoxetine treatment in depression may be associated with an increase in choline-creatine ratios in the basal ganglia.

Residual symptoms in depressed patients who respond acutely to fluoxetine.

BACKGROUND: Antidepressants have unequivocal efficacy as compared with placebo, but many patients have residual symptoms despite a robust response to antidepressant therapy. The purpose of this study is to assess residual symptoms in outpatients who respond acutely to fluoxetine. METHOD: Two hundred and fifteen outpatients with major depressive disorder as assessed with the Structured Clinical Interview for DSM-III-R (SCID-P) were treated openly with fluoxetine 20 mg/day for 8 weeks. One hundred and eight (50.2%) were considered full responders (final 17-item Hamilton Rating Scale for Depression [HAM-D] score < or =7). Percentages of full responders who continued to have subthreshold or full major depressive disorder symptoms were calculated. The relationship between residual symptoms and Axis I and Axis II (assessed with SCID-II for personality disorders) comorbidity was assessed. RESULTS: Of the 108 responders, 19 (17.6%) had no subthreshold or threshold SCID-P major depressive disorder symptoms, while 28 (25.9%) had 1 symptom, and 61 (56.5%) had 2 or more symptoms. No statistically significant relationships were found between number of residual symptoms and selected Axis I comorbid conditions or total number of Axis II disorders. CONCLUSION: Less than 20% of full responders to fluoxetine by HAM-D criteria were free of all SCID-P subthreshold and threshold major depressive disorder symptoms after 8 weeks of treatment. While depressed patients benefit from antidepressants, most continue to have some symptoms of depression. The high prevalence of residual symptoms among antidepressant responders suggests the need for further study including whether residual symptoms abate with longer treatment or increased dose of fluoxetine. Other strategies, such as cognitive behavioral therapy, may be needed to address residual symptoms.

Efficacy of fluvoxamine in the treatment of major depression with comorbid anxiety disorders.

BACKGROUND: Major depression with comorbid anxiety disorder is associated with poor antidepressant outcome compared with major depression without comorbid anxiety disorder. The purpose of our study was to assess changes in depressive symptoms and anxiety levels in outpatients with major depression with comorbid anxiety disorder following 12 weeks of open treatment with fluvoxamine. METHOD: We enrolled 30 outpatients (mean +/- SD age = 39.4 +/- 11.3 years; 16 women and 14 men) with DSM-IV major depressive disorder accompanied by one or more current comorbid DSM-IV anxiety disorders in our study. Patients were treated openly with fluvoxamine initiated at 50 mg/day, with an upward titration to a maximum of 200 mg/day (mean +/- SD dose = 143 +/- 45 mg/day). Efficacy assessments included the 17-item Hamilton Rating Scale for Depression (HAM-D-17) and Clinical Global Impressions-Severity of Illness (CGI-S) and Improvement (CGI-I) scales for both depression and anxiety. Intent-to-treat analysis was used to assess outcome. RESULTS: The mean +/- SD number of comorbid anxiety disorders per patient was 2.1 +/- 1.1. Following fluvoxamine treatment, the mean +/- SD HAM-D-17 score dropped from 20.2 +/- 3.3 to 1 1.0 +/- 7.0 (p < .0001). The mean +/- SD depression CGI-S score dropped from 4.0 +/- 0.6 to 2.4 +/- 1.1 (p < .0001), and the mean +/- SD anxiety CGI-S score decreased from 4.1 +/- 0.8 to 2.5 +/- 1.2 (p < .0001). Eighteen (60%) of the 30 patients had CGI-I scores < or = 2 for both anxiety and depression at endpoint, with 53% showing a > or = 50% reduction in HAM-D-17 scores at endpoint. CONCLUSION: Although preliminary, our findings suggest that fluvoxamine is effective in treating outpatients with major depression with comorbid anxiety disorder, having a significant effect on both depression and anxiety symptoms. Further double-blind, placebo-controlled trials are needed, in a larger sample, to confirm our findings.

Anger attacks in patients with depression.

Anger attacks are sudden intense spells of anger that resemble panic attacks but lack the predominant affects of fear and anxiety associated with panic attacks. They typically occur in situations in which an individual feels emotionally trapped and experiences outbursts of anger that are later described by the patient as being uncharacteristic and inappropriate to the situation at hand. Anger attacks consist of both behavioral and autonomic features, and various criteria and an Anger Attacks Questionnaire have been designed to identify the presence of these attacks. The prevalence of anger attacks in depressed patients is approximately 30% to 40%, and the attacks have disappeared in 53% to 71% of depressed patients treated with fluoxetine, sertraline, or imipramine. This article discusses the development of the concept of anger attacks, the presence of anger attacks in depression and other psychiatric disorders, and the current treatment of anger attacks.

[Percutaneous revascularization of chronic iliac artery occlusions with primary stent placement].

BACKGROUND: Percutaneous transluminal angioplasty is a well established treatment method for aorto iliac stenoses. However its success is limited in arterial occlusions and vascular stent placement can improve the results. AIM: To assess the effectiveness of percutaneous revascularization with stent placement in patients with chronic iliac artery occlusions. PATIENTS AND METHODS: Twenty six patients (18 male) aged 47 to 82 years, with iliac artery occlusions lasting six or more weeks were treated. Fourteen had involvement of common iliac artery, five had involvement of external iliac artery and seven of both. The occluded segment length ranged from 3.5 to 12 cm. According to the Society of Cardiovascular Surgery/International Society for Cardiovascular Surgery classification, 22 patients had category 1 claudication, 10 were in category 2, 12 in category 3 and two in category 4. RESULTS: A technical success was obtained in 23 patients and clinical success in 21. After the intervention, the anklearm index improved from 0.49 +/- 0.12 to 0.88 +/- 0.18 (p < 0.001). Permeability after 12 months of follow up was 81% and after 36 months, 65%. Four patients had complications; one had a vascular perforation, two had an acute occlusion and one had an asymptomatic distal embolization. All these were solved using endovascular techniques. CONCLUSIONS: Percutaneous revascularization with stent placement is a valid alternative to surgery in selected patients with chronic iliac artery occlusion.

[Colorectal neoplasms. Treatment of obstruction with autoexpanding metal stents].

BACKGROUND: Expandable metal stents can be used as a palliative or pre surgical method to decompress obstructing colonic carcinomas. AIM: To assess the effectiveness of these stents in the treatment of obstructive colonic carcinoma. PATIENTS AND METHODS: Expandable metal stents were placed in nine patients with the diagnosis of colorectal carcinoma and with clinical and radiographic signs of intestinal obstruction. Stents were placed under fluoroscopic guidance in nine patients and with endoscopic help in 2. The indications were palliative treatment in 7 and pre surgical decompression in 2 patients. RESULTS: Stent placement was successful in all patients. One patient presented a self limited rectal bleeding after the procedure. Obstruction was relieved in less than 24 hours after the procedure. CONCLUSION: Expandable metal stent placement is an effective means of relieving intestinal obstruction caused by colorectal carcinoma.

[Treatment of refractory ascites using a transjugular intrahepatic portosystemic shunt (TIPS). Clinical case].

Approximately, 10% of cirrhotic patients with ascites become refractory to medical treatment, a condition that reduces overall survival. TIPS is a therapeutic alternative for the management of refractory ascites. It corrects sinusoidal portal hypertension, becoming a rational and relatively safe therapeutic approach. The most frequent complications of TIPS are the development of hepatic encephalopathy and a high incidence of shunt stenosis or occlusion after one year of follow-up. We report a 43 years old alcoholic cirrhotic male with ascites refractory to medical treatment, that required multiple large volume paracentesis, whose clinical condition deteriorated progressively. A TIPS was successfully placed with a rapid and complete resolution of ascites and marked improvement of his clinical condition. During the ensuing six months the patient remained in excellent conditions, but was lost from follow-up and resumed excessive alcohol intake. Eight months after TIPS placement he had an upper gastrointestinal bleeding and died.

A quantitative magnetic resonance imaging study of caudate and lenticular nucleus gray matter volume in primary unipolar major depression: relationship to treatment response and clinical severity.

The authors investigated whether there were differences in caudate and lenticular nucleus volumes in depressed patients relative to comparison subjects, and whether differences in basal ganglia volume were associated with treatment response to fluoxetine. Brain magnetic resonance images were obtained from 38 unipolar depressed patients and 20 matched comparison subjects. Patients were divided into groups of 'responders' and 'non-responders' based on change in the 17-item Hamilton Depression Rating Scale (HDRS) score after a 10-week open trial of fluoxetine, 20 mg/day. There were no group mean differences in caudate and lenticular nucleus volumes between patients and comparison subjects. Female treatment responders tended to have larger caudate nucleus volumes than male 'responders', and also larger right caudate nucleus volumes than their female 'non-responder' counterparts. Baseline HDRS scores correlated negatively with left caudate nucleus volume in depressed patients. Thus, in mild to moderately depressed patients, we were unable to find differences in caudate and lenticular nucleus-gray matter volumes relative to comparison subjects. One possible reason is that caudate nucleus-gray matter volume and severity of depression are inversely correlated, suggesting that severity of depression may be an important covariate when comparing caudate volumes in depressed patients and control subjects.

Selective serotonin reuptake inhibitor discontinuation syndrome: a randomized clinical trial.

BACKGROUND: Recent reports describe discontinuation-emergent adverse events upon cessation of selective serotonin reuptake inhibitors including dizziness, insomnia, nervousness, nausea, and agitation. We hypothesized that interruption of fluoxetine treatment would be associated with fewer discontinuation-emergent adverse events than interruption of sertraline or paroxetine treatment, based on fluoxetine's longer half-life. METHODS: In this 4-week study, 242 patients with remitted depression receiving maintenance therapy with open-label fluoxetine, sertraline, or paroxetine for 4-24 months had their maintenance therapy interrupted with double-blind placebo substitution for 5-8 days. The Symptom Questionnaire (SQ), the Discontinuation-Emergent Signs and Symptoms checklist, the 28-item Hamilton Depression Rating Scale, and the Montgomery-Asberg Depression Rating Scale were used to assess somatic distress and stability of antidepressant response. RESULTS: Two hundred twenty patients (91%) completed the study. Following interruption of therapy, fluoxetine-treated patients experienced fewer discontinuation-emergent events than either sertraline-treated or paroxetine-treated patients (p < .001). The mean SQ somatic symptom scale score in fluoxetine-treated patients was significantly lower than that in sertraline-treated and paroxetine-treated patients (p < .001). Fluoxetine-treated patients also experienced less reemergence of depressive symptoms than sertraline-treated or paroxetine-treated patients (p < .001). CONCLUSIONS: Abrupt interruption of antidepressant therapy for 5-8 days was associated with the emergence of new somatic and psychological symptoms in patients treated with paroxetine and to a lesser degree sertraline, with few symptoms seen with fluoxetine.
