Possible new ways in the pharmacological treatment of bipolar disorder and comorbid alcoholism

A Prospective Comparison of Bipolar I and II Subjects With and Without Comorbid Alcohol Dependence From the COGA Dataset

Objective: Comorbidity of alcohol use disorders in bipolar subjects is high as indicated by epidemiological and clinical studies. Though a more severe course of bipolar disorder in subjects with comorbid alcohol dependence has been reported, fewer studies considered the longitudinal course of alcohol dependence in bipolar subjects and the prospective course of comorbid bipolar II subjects. Beside baseline analysis, longitudinal data of the COGA (Collaborative Study on Genetics in Alcoholism) were used to evaluate the course of bipolar I and II disordered subjects with and without comorbid alcohol dependence over more than 5 years of follow-up. Methods: Characteristics of bipolar disorder, alcohol dependence and comorbid psychiatric disorders were assessed using semi-structured interviews (SSAGA) at baseline and at a 5-year follow-up. Two hundred twenty-eight bipolar I and II patients were subdivided into groups with and without comorbid alcohol dependence. Results: Of the 152 bipolar I and 76 bipolar II patients, 172 (75, 4%) had a comorbid diagnosis of alcohol dependence. Bipolar I patients with alcohol dependence, in particular women, had a more severe course of bipolar disorder, worse social functioning and more suicidal behavior than all other groups of subjects during the 5-year follow-up. In contrast, alcohol dependence improved significantly in both comorbid bipolar I and II individuals during this time. Conclusions: A 5-year prospective evaluation of bipolar patients with and without alcohol dependence confirmed previous investigations suggesting a more severe course of bipolar disorder in comorbid bipolar I individuals, whereas bipolar II individuals were less severely impaired by comorbid alcohol use disorder. While severity of alcohol dependence improved during this time in comorbid alcohol-dependent bipolar I patients, the unfavorable outcome for these individuals might be due to the higher comorbidity with personality and other substance use disorders which, together with alcohol dependence, eventually lead to poorer symptomatic and functional clinical outcomes.

Gabapentinoids in penitentiaries: An abuse and addiction research

Objectives

This study aims to examine the abuse and addiction of gabapentinoids in penal institutions.

Patients and methods

Between September 2014 and November 2014, a total of 1,639 participants were administered an electronic questionnaire investigating the drug use and addiction. The questionnaire was requested to be asked and filled by the officers in charge for all voluntary convicts and prisoners in all penitentiaries throughout Turkey.

Results

The rate of answering the questions varied between 20.5% and 100%. It was found that 2% of the participants used pregabalin and gabapentin simultaneously, while 25.2% of them used multiple drugs. The usage rate of pregabalin and gabapentin was higher in some penitentiaries, compared to the normal population. There was a significant positive correlation between the use of gabapentinoids and multiple drugs and alcohol and drug addiction, various withdrawal symptoms, the number of going to the infirmary, and the number of referral to the hospital (p<0.05).

Conclusion

Although gabapentinoids seem to be used in the treatment of addiction, and are proved effective treatment agents. With a definite diagnosis, appropriate follow-up, and timely completion of the treatment, it is necessary to strictly control their use due to the probability of abuse and addiction.
