Biochemical measures in patients with a somatoform pain disorder, before, during, and after treatment with amitriptyline with or without flupentixol.

The possible relationship between a number of biochemical parameters and measures of pain and depression was studied in chronic pain patients without a major depression. In a double-blind crossover study, patients were treated with amitriptyline combined with a low dose of flupentixol or placebo. We investigated whether pretreatment biochemical values correlated with initial data on pain and/or depression, or whether they had predictive value for treatment outcome. We also studied systematically the effect of both treatment regimes on the biochemical parameters themselves and their relation to the plasma levels of amitriptyline. From our results, the possible involvement of the serotonin system in somatoform pain disorder is confirmed and no direct relation with the noradrenergic system could be inferred. The lack of involvement of a number of putative, depression-related, biochemical parameters suggests that affective disorders and pain syndromes do not share all mechanisms in common.

Hypnosis and autogenic training in the treatment of tension headaches: a two-phase constructive design study with follow-up.

Tension headaches can form a chronic (very long duration) condition. EMG biofeedback, relaxation training and analgesia by hypnotic suggestion can reduce the pain. So far, no differences have been demonstrated between the effects of various psychological treatments. In a constructively designed study, we firstly compared an abbreviated form of autogenic training to a form of hypnotherapy (future oriented hypnotic imagery) which was not presented as hypnosis and secondly we compared both treatments to the same future oriented hypnotic imagery, but this time explicitly presented as hypnosis. The three treatments were equally effective at post-treatment, but after a 6-month follow-up period, the future oriented hypnotic imagery which had been explicitly presented as hypnosis was superior to autogenic training. Contrary to common belief, it could be demonstrated that the therapists were as effective with the treatment modality they preferred as with the treatment modality they felt to be less remedial.

Autogenic training and self-hypnosis in the control of tension headache.

This study compares autogenic training and training in multiple self-hypnosis strategies in a sample of 56 patients diagnosed as having chronic tension headache on the basis of medical evaluation by a neurologist. At posttreatment and follow-up, no differences between the two treatment regimens in the reduction of headache and psychological distress were observed. During treatment, patients reduced their headache activity and level of psychological distress significantly in contrast to the waiting-list period (p < 0.05). Follow-up measurements indicated that therapeutic improvement was maintained (p < 0.05). Short-term and long-term pain reduction was accompanied by an increase in perceived pain control (p < 0.003). Moreover, those patients who attributed the pain reduction obtained during therapy to their own efforts manifested long-term pain reduction (p < 0.003).

Chronic pain beyond patienthood.

Forty nonconsumers (subjects with pain lasting for more than 1 year who had not consulted a doctor because of it during the preceding year) were compared with 46 chronic patients at a pain clinic. The mean duration of the nonconsumers' pain was twice as long as that of the patients'. Although their pain intensity, as assessed with pain diaries, did not differ, their estimated pain intensity was less than that of the pain patients; they took fewer analgesics, were less functionally impaired, made less use of coping strategies associated with poor adjustment, were less depressed, and expected less help from external resources. The "non-consumer attitude" appears to be independent of the duration of the pain complaints.

Does addition of low-dose flupentixol enhance the analgetic effects of low-dose amitriptyline in somatoform pain disorder?

In a double-blind, crossover study, the effects of 75 mg amitriptyline alone during 5 weeks on pain intensity were compared with the effects of a combination of 75 mg amitriptyline and 3 mg flupentixol during 5 weeks in 34 patients with somatoform pain disorder. Both treatments resulted in a statistically significant reduction in pain. However, pain reduction in the combined treatment did not differ from that in the treatment with amitriptyline as a single drug. Neither tardive dyskinesias nor other serious side effects were observed. The results do not support the clinical practice of adding low-dose neuroleptics to low-dose antidepressants in the treatment of somatoform pain disorder.

Autogenic training and future oriented hypnotic imagery in the treatment of tension headache: outcome and process.

The aim of the present study was (a) to investigate the relative efficacy of autogenic training and future oriented hypnotic imagery in the treatment of tension headache and (b) to explore the extent to which therapy factors such as relaxation, imagery skills, and hypnotizability mediate therapy outcome. Patients were randomly assigned to the 2 therapy conditions and therapists. 55 patients (28 in the autogenic therapy condition and 27 in the future oriented hypnotic imagery condition) completed the 4 therapy sessions and 2 assessment sessions. No significant main effect or interaction effects for treatment condition or therapist was revealed. A significant effect for time in analyzing scores for headache pain, pain medication usage, depression, and state anxiety was found. In the self-hypnosis condition, pain reduction proved to be associated with depth of relaxation during home practice (as assessed with diaries) and capacity to involve in imagery (as assessed with the Dutch version [van der Velden & Spinhoven, 1984] of the Creative Imagination Scale [Barber & Wilson, 1978/79; Wilson & Barber, 1978]). After statistically controlling for relaxation and imagery, hypnotizability scores (as assessed with the Dutch version [Oyen & Spinhoven, 1983] of the Stanford Hypnotic Clinical Scale [Morgan & J.R. Hilgard, 1975, 1978/79]) were significantly correlated with ratings of pain reduction. Results are discussed in the context of the neo-dissociation and social-cognitive model of hypnoanalgesia. The clinical relevance and the methodological shortcomings of the present study are also critically assessed.

Low dose amitriptyline in chronic pain: the gain is modest.

In the double-blind placebo-controlled study presented here, the effects were investigated of a low dose of amitriptyline (75 mg) in patients with chronic pain of various origins. The active drug was superior to placebo in reducing pain intensity. The reduction was small. In the second treatment week, the amitriptyline treated patients slept longer. No differences between active drug and placebo were found with respect to daily activities or use of analgesics. Based on our data and those of other studies, it is concluded that amitriptyline (and other antidepressants) in low doses does have a positive effect on the intensity and some other aspects of chronic pain, but that the effect is modest. It must be kept in mind that chronic pain is a very treatment-resistant condition. Therefore, even modest positive effects may be worthwhile.

Therapeutic drug monitoring of amitriptyline: impact of age, smoking and contraceptives on drug and metabolite levels in bulimic women.

Concentrations of amitriptyline (AT), nortriptyline (NT) and E-10-hydroxynortriptyline (E-10-OH-NT) were measured in 18 women with bulimia receiving 100 mg AT/day for at least 6 wk. After onset of treatment between days 36 and 57 there is a decrease in AT and an increase in E-10-OH-NT concentrations, probably due to an autoinductive effect on hydroxylation. The estimated mean (+/- SD; range; n) elimination half-life time of AT was 14.0 (+/- 7.8 h; 7.5-38.5 h; 14). On day 36, AT concentrations in females using oral contraceptives (OC) were higher than in non-users of OC, which indicates inhibition of AT metabolism by OC. In all smokers the E-10-OH-NT concentrations on day 36 were lower than in non-smokers. Our findings suggest induction of N-demethylation and glucuronidation by smoke components.

Analgesic and antidepressive effects of low-dose amitriptyline in relation to its metabolism in patients with chronic pain.

The analgesic and antidepressive effects of amitriptyline (AT) in relation to its kinetics and metabolism were studied in 19 outpatients with chronic pain who received a daily dose of 75 mg AT for at least 6 weeks. Riboflavin was added to the medication to check compliance. On days 0, 4, and 8 and weeks 3, 6, 9, and 12 after the start of dosing, blood samples were drawn from the patients 10 +/- 1 hours after the first morning dose and a sample of the first morning urine was taken to check riboflavin. Serum levels of AT and its metabolites, especially nortriptyline (NT) and E-10-hydroxy-nortriptyline (E-10-OH-NT), were measured by HPLC. On day 0 and at 3, 6, and 12 weeks the severity of depression was scored by means of a self-rating depression scale and pain intensity scores were measured. In addition, after 6 weeks of dosing patients estimated their percentage of pain in comparison with baseline. Mean (+/- SD) steady-state concentrations of AT, NT, and E-10-OH-NT were 36 +/- 23.5, 28 +/- 14.9, and 52 +/- 23.7 micrograms/L, respectively, in male patients (n = 8; age 45 +/- 7.4 years) and 34 +/- 14.6, 45 +/- 25.1, and 40 +/- 15.6 micrograms/L, respectively, in female patients (n = 11; age 46 +/- 6.8 years). There was a significant sex-related difference in the NT/AT ratio, which was higher in women.(ABSTRACT TRUNCATED AT 250 WORDS)

The Hamilton Depression Rating Scale (HDRS); changes in scores as a function of training and version used.

The co-existence of different versions of the Hamilton Depression Rating Scale (HDRS) may introduce a source of error in depression research. In a training procedure, based on 16 videotapes, over 900 scores were used to investigate differences between two prominent versions. The HDRS published by Bech et al. in 1986 produced significantly lower total scores than the original HDRS presented by Hamilton in 1960. Previous experience of the raters, both in psychiatry and in the use of the scale, increased the scores in a nonsignificant way. During the training raters' scores increased significantly. These effects were small, one point each in the total scores, but they were consistent throughout our material. In depression research, training procedures and the exact version of the scales used should be specified.
