Methods: In 115 patients with panic disorder with or without agoraphobia and in 124 control subjects without a history of psychiatric illness, we assessed separation anxiety during childhood, retrospectively, using DSM-IV and ICD-10 criteria and the Separation Anxiety Symptom Inventory (SASI). In addition, actual separation experiences from age 0 to 15 years were assessed, retrospectively. Results: A total of 22.6% of the patients and 4.8% of the Control subjects fulfilled both DSM-IV and ICD-10 criteria for childhood separation anxiety (chi(2) = 11.8; P < 0.0001). Further, 57.4% ofthepatients and 37.9% of the control subjects reported actual separation experiences during their childhood (chi(2) = 9. 09, P < 0.003). Separation anxiety and actual separation experiences, however, were independent of each other.

Although many of these patients are regular smokers, it has not been examined whether psychological or neurobiological effects induced by the selective 5-HT1A-receptor agonist, ipsapirone, are affected by the smoking status of the patients. In order to clarify this question neuroendocrine challenges with oral doses of ipsapirone (0.3 mg/kg) and placebo were performed in 39 patients with PDA, and results were compared between patients who smoked (>10 cigarettes per day, n = 17) and patients who had been non-smokers for at least two years (n = 22). Patients who were smokers (but did not smoke during the challenge procedure) had significantly reduced baseline concentrations of cortisol and a significantly lower body temperature. In comparison to placebo, administration of ipsapirone was associated with significant increases of various psychological symptoms and plasma cortisol concentrations. The subgroup of PD patients who were smokers showed significantly higher cortisol responses to ipsapirone than non-smokers. In conclusion, smoking status has to be taken into account when assessing the responsiveness of 5-HT1A receptors in patients with psychiatric disorders. The prevention of smoking during challenge sessions might not be the ideal approach in heavy smokers, since sudden abstinence from smoking is likely to affect neurobiological and possibly psychological responses to ipsapirone."],["dc.identifier.doi","10.1016/S0893-133X(02)00298-1"],["dc.identifier.isi","000176402600014"],["dc.identifier.pmid","12093600"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41188"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Elsevier Science Inc"],["dc.relation.issn","0893-133X"],["dc.title","Smoking modulates neuroendocrine responses to ipsapirone in patients with panic disorder"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
