Slovenian Version of the Drug-Induced Extrapyramidal Symptoms Scale: Evaluation of Interrater and Test-Retest Reliability.

AIM: The Drug-Induced Extrapyramidal Symptom Scale (DIEPSS) is a multidimensional rating scale for the assessment of drug-induced extrapyramidal symptoms (EPS), developed in 1994. It is suitable for evaluating EPS considering the degree of influence EPS has on daily activities and the subjective distress that it causes. METHOD: This study to evaluate the interrater and test-retest reliability of the DIEPSS Slovenian version conducted at the University Medical Center Maribor in Slovenia in November 2018. RESULTS: Six raters performed the interrater assessment of 135 DIEPSS video clips with recordings of patients with EPS. A second assessment was then performed by 2 raters to evaluate the test-retest reliability, which was high (interclass correlation coefficients from 0.743 to 0.936). CONCLUSIONS: The results for the Slovenian language version of the DIEPSS show high interrater and test-retest reliability, with high concordance rates for all evaluated items (interclass correlation coefficient > 0.8).

Associations of NLRP3 and CARD8 gene polymorphisms with alcohol dependence and commonly related psychiatric disorders: a preliminary study.

We investigated two functional polymorphisms in NLRP3 inflammasome genes (NLRP3 rs35829419 and CARD8 rs2043211) and their association with alcohol dependence and related anxiety, depression, obsession-compulsion, or aggression in 88 hospitalised alcohol-dependent patients, 99 abstinent alcohol-dependent participants, and 94 controls, all male Caucasian. Alcohol dependence-related psychiatric disorders were assessed with the Zung Depression and Anxiety scale, Buss-Durkee Hostility Inventory, Alcohol Use Disorders Identification Test, Brief Social Phobia Scale, Obsessive Compulsive Drinking Scale, and Yale-Brown Obsessive-Compulsive Scale. For genotyping we used the allele-specific quantitative polymerase chain reaction-based methods. The three groups differed significantly in CARD8 rs2043211 distribution (P=0.049; chi-squared=9.557; df=4). The NLPR3 rs35829419 polymorphism was not significantly associated with alcohol dependence. In hospitalised alcohol-dependent patients the investigated polymorphisms were not associated with scores indicating alcohol consumption or comorbid symptoms. In abstinent alcohol-dependent subjects homozygotes for the polymorphic CARD8 allele presented with the highest scores on the Zung Anxiety Scale (p=0.048; df=2; F=3.140). Among controls, CARD8 genotype was associated with high scores on the Obsessive Compulsive Drinking Scale (P=0.027; df=2; F=3.744). In conclusion, our results reveal that CARD8 rs2043211 may play some role in susceptibility to alcohol dependence, expression of anxiety symptoms in abstinent alcohol-dependent subjects, and in obsessive compulsive drinking in healthy controls. However, further studies with larger cohorts are required to confirm these preliminary findings.
