Sub-threshold depression and antidepressants use in a community sample: searching anxiety and finding bipolar disorder

<p>Abstract</p> <p>Background</p> <p>To determine the use of antidepressants (ADs) in people with sub-threshold depression (SD); the lifetime prevalence of mania and hypomania in SD and the link between ADs use, bipolarity and anxiety disorders in SD.</p> <p>Methods</p> <p>Study design: community survey. Study population: samples randomly drawn, after stratification from the adult population of municipal records. Sample size: 4999 people from seven areas within six Italian regions. Tools: Questionnaire on psychotropic drug consumption, prescription; Structured Clinical Interview NP for DSM-IV modified (ANTAS); Hamilton Depression Rating Scale (HAM-D); Mood Disorder Questionnaire (MDQ); Short Form Health Survey (SF-12). SD definition: HAM-D > 10 without lifetime diagnosis of Depressive Episode (DE).</p> <p>Results</p> <p>SD point prevalence is 5.0%. The lifetime prevalence of mania and hypomania episodes in SD is 7.3%. Benzodiazepines (BDZ) consumption in SD is 24.1%, followed by ADs (19.7%). In SD, positive for MDQ and comorbidity with Panic Disorder (PD) or Generalized Anxiety Disorders (GAD) are associated with ADs use, whereas the association between a positive MDQ and ADs use, without a diagnosis of PD or GAD, is not significant. Only in people with DE the well-being (SF-12) is higher among those using first-line antidepressants compared to those not using any medication. In people with SD no significant differences were found in terms of SF-12 score according to drug use.</p> <p>Conclusions</p> <p>This study suggests caution in prescribing ADs to people with SD. In people with concomitant anxiety disorders and SD, it should be mandatory to perform a well-designed assessment and evaluate the presence of previous manic or hypomanic symptoms prior to prescribing ADs.</p

Adjunctive gabapentin in patients with intellectual disability and bipolar spectrum disorders

The aim of the present study was to assess the efficacy of adjunctive gabapentin (GBP) in the treatment of patients with intellectual disability (ID) and bipolar spectrum disorders. Ten affected subjects with demonstrable increases in symptomatology during 'significant' life events which had interfered with or induced the interruption of their rehabilitation programmes were chosen for this study. The meaning of 'significant' was defined for each patient as a frequently repeated life event which had elicited a marked increase in symptoms on at least two occasions. Gabapentin (300-900 mg day-1) was added to the standard therapy. The subjects' psychopathological conditions during the significant life event were assessed by means of standardized tools both before and after adjunctive therapy with GBP. A positive response to therapy was observed, with subsequent improvement of psychopathological conditions, particularly for anxiety and depressive symptoms. The promising results obtained with GBP suggest the need for further trials. Adjunctive GBP may become an alternative treatment approach for patients with ID in whom traditional mood-stabilizing agents have frequent contraindications

The clinical use of gabapentin in bipolar spectrum disorders

Background: with increasing awareness of lithium's limitations, several new anticonvulsants had been tested for their mood stabilisation during recent years. Among the innovative third generation mood stabilizing anticonvulsants, gabapentin (GBP) seems to have a broad spectrum of efficacy, although no certain data are available as to its efficacy and use in clinical practice. Accordingly, an extensive review on this subject has been carried out. Methods: A computer-generated search of the biomedical literature and abstract books of the more important scientific psychiatric congresses until June 2000 was undertaken to identify all pertinent case reports, case series and studies of GBP as monotherapy or adjunctive therapy in mood disorders. We identified 40 open-label studies on the use of GBP in at least 600 patients with bipolar disorder (BP), manic, depressed, or mixed episodes and unipolar depression and four controlled studies. Results: The 40 open-label studies and two of the controlled trials suggested that GBP may have a role as adjunctive agent in the treatment of patients with bipolar disorders particularly when complicated by co-morbid anxiety disorder or substance abuse. GBP is usually very well tolerated and has no pharmacological interference with other mood stabilisers. However, in the other two double-blind studies GBP has not been found to be efficacious in the treatment of refractory mania or refractory bipolar depression. Conclusions: Although failing to show clear antimanic efficacy in randomized trials, gabapentin still remains a clinically useful agent when it comes to combination treatment in refractory and co-morbid patients.
