ABSTRACT

This study examined the 3-month follow-up effects of a pain coping skills intervention in African American adults with sickle cell disease. Sixty-seven participants were randomly assigned to either a coping skills condition or a disease-education control condition. Multivariate analyses applied to summary measures of coping, laboratory pain perception, and clinical measures indicated that participants in the coping intervention reported significantly lower laboratory pain and significantly higher coping attempts at 3-month follow-up in comparison with the control condition. Multilevel random effects models applied to prospective daily diaries of daily pain, health care contacts, and coping practice indicated that on pain days when participants practiced their strategies, they had less major health care contacts in comparison with days when they did not use strategies.

ABSTRACT

Winter depressions in seasonal affective disorder (SAD) are associated with central serotonergic (5-HT) dysfunction. SAD patients demonstrate rather specific, state-dependent, abnormal increases in 'activation-euphoria' ratings following intravenous infusion of the 5-HT receptor agonist meta-chlorophenylpiperazine (m-CPP). Several studies are also consistent with abnormal serotonergic regulation of the hypothalamic-pituitary-adrenal (HPA) axis in SAD. Here, we investigated the effects of the 5-HT1A receptor partial agonist ipsapirone, which produces behavioral effects and HPA-axis activation, to further characterize the 5-HT receptor subtype-specificity of these disturbances in SAD. Eighteen SAD patients and 18 control subjects completed two drug challenges (ipsapirone 0.3 mg/kg and placebo) separated by 3-5 days in randomized order. We measured behavioral responses with the NIMH self-rating scale, and plasma ACTH, cortisol, and prolactin concentrations. Compared with placebo, ipsapirone was associated with significant increases in self-rated 'functional deficit' and 'altered self-reality', and in each of the hormones. There were no differences between groups on any measures. The level of depression in SAD patients was inversely correlated with their ipsapirone-induced cortisol responses. There were significant drug x order effects on baseline 'anxiety' scores, ACTH and cortisol concentrations, such that subjects were significantly more stressed (higher 'anxiety', ACTH and cortisol) prior to their first challenge compared with their second. In conclusion, post-synaptic 5-HT1A receptors appear to function normally in SAD. The previously observed m-CPP-induced behavioral abnormality may be mediated by either 5-HT2C or 5-HT7 receptors.

ABSTRACT

This study examined daily reports of pain, medication use, health care use, and activity reduction in adults with sickle cell disease, and their association with stress. Participants were 53 adults with sickle cell disease. They completed the Daily Hassles questionnaire at the start of the study, and they kept daily records of pain and pain response over the following 14 days. On average, patients reported pain on 6.5 days of the 14-day study period. The average pain intensity rating during a painful episode was 4.4 on a 10-point scale. Pain was most often managed at home. Patients took medication (analgesics and/or narcotics) on 80% of the days they experienced pain, and they were more likely to use medication, particularly narcotics, as pain levels increased. At higher pain levels some patients also utilized a range of health care services. On average, patients also cut back considerably on household and social activities, especially when pain reached a level of over 5 on the 10-point scale. Those who were employed, however, were likely to continue to work, even when in pain. In addition, stress had significant positive associations with average pain intensity as well as reductions in household and social activities. Furthermore, stress predicted activity reductions even after controlling for pain intensity. Stress was unrelated to medication and health care use in this study.

ABSTRACT

This study was designed to examine whether brief training in cognitive coping skills would enhance pain coping strategies and alter pain perception in children and adolescents with sickle cell disease (SCD). Forty-nine participants with SCD were randomly assigned to either a cognitive coping skills condition or a standard care control condition. At pre- and posttesting, coping strategies and pain sensitivity using laboratory pain stimulation were measured. Results indicated that in comparison to the randomly assigned control condition, brief training in cognitive coping skills resulted in decreased negative thinking and lower pain ratings during low intensity laboratory pain stimulation.

ABSTRACT

To test the hypothesis that cyanocobalamin (vitamin B12) is an effective treatment for winter seasonal affective disorder (SAD). 2 weeks of double-blind placebo washout, followed by random assignment to parallel treatments for 2 weeks with cyanocobalamin vs. placebo. Observations were made during weekly outpatient visits. All subjects met criteria for SAD. 27 patients were studied. After the washout period, 14 were randomly assigned to 1.5 mg cyanocobalamin (3 x/day) and 13 remained on placebo on the same schedule. 29 item SIGH-SAD scores were used to determine antidepressant efficacy. No significant differences were found in the responses between the two groups. Cyanocobalamin does not appear to be an effective short-term treatment for depression in SAD patients. The usefulness as a treatment for SAD of the methylated form of Vitamin B12, which has been used extensively in related studies, remains to be explored.
