Attempted Suicide and Alcoholism in Bipolar Disorder: Clinical and Familial Relationships
ABSTRACT This study examined the clinical and familial relationships between comorbid alcoholism and attempted suicide in affectively ill relatives of probands with bipolar I disorder.
In 71 families ascertained for a genetic linkage study, 337 subjects with major affective disorder were assessed by using the Schedule for Affective Disorders and Schizophrenia-Lifetime Version.
Subjects with bipolar disorder and alcoholism had a 38.4% lifetime rate of attempted suicide, whereas those without alcoholism had a 21.7% rate. Attempted suicide among subjects with bipolar disorder and alcoholism clustered in a subset of seven families. Families with alcoholic and suicidal probands had a 40.7% rate of attempted suicide in first-degree relatives with bipolar disorder, whereas other families had a 19.0% rate.
Comorbid alcoholism was associated with a higher rate of attempted suicide among family members with bipolar disorder. Attempted suicide and alcoholism clustered in a subset of families. These relationships may have a genetic origin and may be mediated by intoxication, mixed states, and/or temperamental instability.

- "Although exploring familiarity is more difficult for BP-II than for BP-I disorder, BP-II disorder also seems to run in families with specific aggregation patterns [92,110- 113]. Other several associated clinical phenomena, such as psychosis  , comorbidities  , and suicidality , and some characteristics of the course of illness, such as rapid cycling , age of onset  , and episode frequency  may come together in BP families. Moreover, BP and UP disorders seem also to run together in families, as BP patients frequently have UP family members and vice versa  . "
ABSTRACT: In this article we aimed to: (1) review literature concerning the clinical and psychopathologic characteristics of Bipolar (BP) depression; (2) analyze an independent sample of depressed patients to identify any demographic and/or clinical feature that may help in differentiating mood disorder subtypes, with special attention to potential markers of bipolarity. A sample of 291 depressed subjects, including BP -I (n = 104), BP -II (n = 64), and unipolar (UP) subjects with (n = 53) and without (n = 70) BP family history (BPFH), was examined to evidence potential differences in clinical presentation and to validate literature-derived markers of bipolarity. Demographic and clinical variables and, also, single items from the Hamilton Depression Rating Scale (HDRS), the Montgomery-Asberg Depression Rating Scale (MADRS), and the Young Mania Rating Scale (YMRS) were compared among groups. UP subjects had an older age at onset of mood symptoms. A higher number of major depressive episodes and a higher incidence of lifetime psychotic features were found in BP subjects. Items expressing depressed mood, depressive anhedonia, pessimistic thoughts, and neurovegetative symptoms of depression scored higher in UP, whereas depersonalization and paranoid symptoms' scores were higher in BP. When compared with UP, BP I had a significantly higher incidence of intradepressive hypomanic symptoms. Bipolar family history was found to be the strongest predictor of bipolarity in depression. Overall, our findings confirm most of the classical signs of bipolarity in depression and support the view that some features, such as BPFH, together with some specific symptoms may help in detecting depressed subjects at higher risk for BP disorder.Comprehensive psychiatry 03/2011; 53(1):24-38.

- "Subjects with a dual diagnosis of both alcohol dependence and an affective disorder have a worse prognosis (Mueller et al., 1994), are more difficult to treat and are more costly to treat than those with either disorder alone (Hoff and Rosenheck, 1999; Hasin et al., 2002; Burns et al., 2005). There is evidence that comorbidity of alcohol dependence with affective disorders has a negative impact upon prognosis measured in terms of rates of remission, relapse and risk of suicide (Potash et al., 2000; Dreissen et al., 2001; Burns et al., 2005). "
ABSTRACT: The aim of this study was to examine prospectively examined predictors of relapse in alcohol dependence with comorbid affective disorder. One hundred and eighty-three unipolar depressed or bipolar alcoholics who completed an integrated inpatient treatment programme for dual diagnosis were assessed at baseline, post-treatment discharge and at 3 and 6 months post treatment. Backwards stepwise likelihood ratio multiple logistic regression was used to investigate the impact of multiple covariates on relapse to alcohol in the 0-3- and 3-6-month period post discharge. The retention rate at 3 months post discharge was 95.3% (177 patients) and at 6 months it was 87.4% (162 patients). Higher level of anxiety at baseline and discharge was significantly associated with relapse at 3, but not at 6 months, in all subjects. Higher baseline alcohol use disorder identification test scores were associated with relapse at 3 and at 6 months. Intention and planning to attend aftercare after discharge from the hospital were associated with non-relapse at 3 and 6 months, respectively. Levels of depression, of elation and of craving at baseline were not significantly predictive of relapse. Those who had relapsed at 3 months were significantly more likely to remain drinking at 6 months. Rehospitalization within the first 3 months post discharge appeared to be protective against further relapse. Baseline patient factors, including levels of anxiety, appear to play a significant role in relapse to alcohol in this difficult to treat population.Alcohol and Alcoholism 11/2010; 45(6):527-33.

- "Between 25 and 60% of bipolar patients make at least one suicide attempt during the course of their illness. In addition, it is estimated that individuals with BD are 30 times more likely to attempt suicide than those without a psychiatric disorder (Chen & Dilsaver 1996; Kessler et al. 1999; Pompili et al. 2008; Potash et al. 2000). However, not all BD patients attempt or suicide, suggesting that, although the presence of environmental factors may be a risk, other elements may also play a role (Neves et al. 2009; Tsuang et al. 2004).

ABSTRACT: We tested the hypothesis that the presence of AKT1 and AKTIP polymorphisms, target genes that encode key proteins in the signaling of dopaminergic and serotonergic systems, is associated with suicidal behavior in bipolar patients. The subjects were 273 patients diagnosed with bipolar disorder I or II (age = 41.4 +/- 12.9). TaqMan single-nucleotide polymorphism genotyping assays (AKT1: rs2494731, rs3803304, rs3730358, rs10149779, rs2494746, rs1130214 and rs249878; AKTIP: rs9302648 and rs7189819) were used. We found that the AKT1 marker showed an association with suicide attempts (rs1130214, P < 0.05) and attempted violent attacks (rs2494746, P < 0.05). One out of the seven tested markers of AKT1 attained significant genotype association with violent attempt (rs2494731; P < 0.05). A significant association was detected in the AKT1 haplotype test. We did not observe an association between suicidal behavior and AKTIP variants and also did not find an interaction between AKTIP and AKT1 polymorphisms. In addition, we found that demographic and clinical data are associated with lifetime history of suicide attempts. Our data suggest that demographic and clinical characteristics and AKT1 single markers and haplotypes, but not AKTIP polymorphisms or interactions between AKT1 and AKTIP, are associated with increased risk for suicidal behavior in bipolar patients.Genes Brain and Behavior 06/2010; 9(4):411-8.
