Posttraumatische Belastungsstörung bei opiatabhängigen methadonsubstituierten Patienten
Bedeutung der Art des Heroinkonsums, der Schwere der Abhängigkeit, der Schwere der psychischen Gesamtsymptomatik und des Geschlechtes
Abstract
Hintergrund: In der vorliegenden Arbeit wird der Zusammenhang zwischen der Posttraumatischen Belastungsstörung (PTBS) nach einem einmalig vorgekommenen Trauma und dem Heroinkonsum, der Schwere der Abhängigkeit und der Schwere der psychischen Gesamtsymptomatik sowie geschlechtsspezifische Unterschiede untersucht. Methode: Bei 48 opiatabhängigen methadonsubstituierten Patienten mit einem traumatischen Ereignis in der Anamnese, welches einmalig erlebt wurde, haben wir anhand mehrerer Interviews das Vorliegen einer PTBS, sowie den Heroingebrauch, die Schwere der Abhängigkeit (Addiction Severity Index; ASI) und die Schwere der psychischen Gesamtsymptomatik (Symptom Checkliste; SCL-90-R) untersucht. Ergebnisse: Insgesamt zeigten 18 Patienten (37 %) eine PTBS (8 Frauen, 10 Männer). Der Heroingebrauch der letzten 6 Monate lag bei der Gruppe mit PTBS signifikant niedriger. Die Schwere der Abhängigkeit war bei der Gruppe mit PTBS signifikant grösser. Bezogen auf die Gesamtgruppe (mit und ohne PTBS) lag die Schwere der Abhängigkeit (ASI) bei den Frauen höher als bei den Männern, insbesondere bezüglich der Bereiche «familiär/sozial» und «Drogen». Bei der Gruppe mit PTBS zeigte sich eine signifikant schwerere Beeinträchtigung durch die Abhängigkeit bezüglich des Bereichs «Arbeit/Unterhalt». Die Schwere der psychischen Gesamtsymptomatik zeigte keinen signifikanten Unterschied zwischen dem Vorliegen oder Fehlen einer PTBS. Diskussion: Die erhobenen Befunde entsprechen dem aktuellen Stand der Forschung über PTBS mit Substanzabhängigkeit. Es konnte zusätzlich gezeigt werden, dass der Heroingebrauch bei der Gruppe mit PTBS nach einmalig aufgetretenem Trauma signifikant niedriger war als der bei der Gruppe ohne PTBS. Es macht deutlich, dass die Rolle der Opioide im Zusammenhang mit den klassischen Symptomen der PTBS komplex ist und weiterer Untersuchungen bedarf.
Background: The aim of this study is to demonstrate the relevance between the posttraumatic stress disorder (PTSD) after a non-recurring trauma and the use of heroin, the severity of addiction and the severity of the overall psychopathology, as well as sex specific differences. Method: 48 patients with an opiate dependency, enrolled in a methadone treatment and with at least one traumatic event, which occurred once in lifetime, were included. Based on several clinical interviews we determined the presence of a diagnosis of PTSD, the use of heroin, the severity of addiction (Addiction Severity Index; ASI) and of the overall psychopathology (Symptom Checklist; SCL-90-R). Results: 18 patients (37 %) had a diagnosis of PTSD (8 women, 10 men). Compared to Non-PTSD patients, PTSD patients had significantly lower use of heroin within the last 6 months while the severity of addiction was significantly higher. Women (with and without PTSD) showed a higher severity of addiction (ASI) particularly with regard to the items “social/family” and “drugs”. The group with PTSD showed a higher severity of addiction regarding the item “work/alimentation”. We found no significant difference of the severity of the overall psychopathology between patients with or without a diagnosis of PTSD. Discussion: The present data are consistent with the previous research findings on PTSD and substance use disorder. The present findings suggest that the use of heroin was significantly lower in the group with PTSD after a non-recurrent trauma. It illustrates that the role of opioids in regard to the classic symptoms of PTSD is diverse and needs to be further examined.
