Early carbon dioxide challenge test may predict clinical response in panic disorder.

We examined whether responses to the carbon dioxide (CO(2)) challenge test were correlated with clinical response. Thirty-four panic disorder patients participated in a CO(2) test after 1 h, 2 weeks and 6 weeks of treatment with clonazepam (2 mg/day) or placebo. The clonazepam group had significantly fewer panic attacks in response to the CO(2) test and the test may predict clinical response.

A breath-holding challenge in panic disorder patients, their healthy first-degree relatives, and normal controls.

Our aim was to observe the induction of panic attacks (PA) symptoms by a breath-hold test in panic disorder (PD) patients as the Diagnostic and Statistical Manual for Mental Disorders 4th edition (DSM-IV) and their healthy first-degree relatives. We randomly selected 26 PD patients, 28 healthy first-degree relatives of probands with PD and 25 normal volunteers with no family history of PD. They were induced to breath-hold for as long as possible four times with a two-min interval between them. Anxiety scales were applied before and after the test. Using specific PA criteria, 46.1% (n=12) PD patients, 7.1% (n=2) first-degree relatives and 4.0% (n=1) control subjects had a PA after the test (chi(2)=7.82, df=2, P=0.023). There was no heart rate, anxiety levels or breath-hold time differences among the groups. In this breath hold challenge test PD patients were more sensitive to breath-hold than first-degree relatives and normal volunteers.

Psychiatric disorders in asthmatic outpatients.

It has been reported that the lifetime prevalence of panic disorder in patients with pulmonary disease is higher than epidemiologic estimates of population prevalence. We evaluated the frequency of anxiety disorders in 86 subjects from the Outpatient Asthma Clinic. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview 4.4 Version (MINI). Forty-five asthmatic patients (52.3%) reported at least one current anxiety disorder. The frequency of panic disorder with or without agoraphobia was 13.9% (n=12) and that of agoraphobia without panic disorder was 26.8% (n=23). Social anxiety and generalized anxiety disorders occurred in 9.3% (n=8) and 24.4% (n=21) of the sample, respectively. Twenty-nine patients (33.7%) reported a major depressive episode. The psychiatric morbidity of the sample was 61.6% (n=53). Our results tend to support the high morbidity of anxiety disorders, particularly panic/agoraphobic spectrum disorders, in asthmatic outpatients.

Nocturnal panic attacks.

The panic-respiration connection has been presented with increasing evidences in the literature. We report three panic disorder patients with nocturnal panic attacks with prominent respiratory symptoms, the overlapping of the symptoms with the sleep apnea syndrome and a change of the diurnal panic attacks, from spontaneous to situational pattern. The implication of these findings and awareness to the distinct core of the nocturnal panic attacks symptoms may help to differentiate them from sleep disorders and the search for specific treatment.
