Psychological treatment may reduce the need for healthcare in patients with Crohn's disease

Background Few published studies examine the influence of psychological treatment on health care utilization in Crohns disease. Methods The present substudy of a prospective, randomized, multicenter trial conducted in 69 of 488 consecutive Crohns disease (CD) patients was designed to investigate the way in which healthcare utilization is influenced by psychotherapy and relaxation in addition to standardized glucocorticoid therapy. Before and after a 1‐year period of standardized somatic treatment the psychotherapy and control groups were compared with regard to hospital and sick‐leave days. Predictors of healthcare utilization were analyzed. Results The comparison between groups before and after psychological treatment showed a significantly higher decrease of mean hospital days (P < 0.03) and sick‐leave days in the treatment group compared with the controls. When a covariate analysis was applied to compare the data at randomization, the difference in hospital days remained statistically a trend (P < 0.1). Multivariate regression analysis detected a significant gender and depression effect for hospital days (cor r2 = 0.114) and a significant gender and age effect for sick‐leave days (cor r2 = 0.112). Conclusion A significant drop in healthcare utilization after psychological treatment demonstrates a clear benefit of this additional therapy. This is important, since the study failed to demonstrate significant changes in the psychosocial status or somatic course of study patients. Clinical and psychological factors influencing these outcomes are discussed. (Inflamm Bowel Dis 2007)

A Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease (SPIRR-CAD) — Rationale and design of a multicenter, randomized trial in depressed patients with CAD

OBJECTIVE Depressive symptoms are highly relevant for the quality of life, health behavior, and prognosis in patients with coronary artery disease (CAD). However, previous psychotherapy trials in depressed CAD patients produced small to moderate effects on depression, and null effects on cardiac events. In this multicentre psychotherapy trial, symptoms of depression are treated together with the Type D pattern (negative affectivity and social inhibition) in a stepwise approach. METHODS Men and women (N=569, age 18-75 years) with any manifestation of CAD and depression scores ≥ 8 on the Hospital Anxiety and Depression Scale (HADS), will be randomized (allocation ratio 1:1) into the intervention or control group. Patients with severe heart failure, acutely life-threatening conditions, chronic inflammatory disease, severe depressive episodes or other severe mental illness are excluded. Both groups receive usual medical care. Patients in the intervention group receive three initial sessions of supportive individual psychotherapy. After re-evaluation of depression (weeks 4-8), patients with persisting symptoms receive an additional 25 sessions of combined psychodynamic and cognitive-behavioral group therapy. The control group receives one psychosocial counseling session. Primary efficacy variable is the change of depressive symptoms (HADS) from baseline to 18 months. Secondary endpoints include cardiac events, remission of depressive disorder (SCID) and Type D pattern, health-related quality of life, cardiovascular risk profile, neuroendocrine and immunological activation, heart rate variability, and health care utilization, up to 24 months of follow-up (ISRCTN: 76240576; NCT00705965).

Identification of polymorphisms in the human 11beta-hydroxysteroid dehydrogenase type 2 gene promoter: functional characterization and relevance for salt sensitivity

Reduced activity of llbeta‐hydroxysteroid dehydrogenase type 2 (11beta‐HSD2) plays a role in essential hypertension and the sensitivity of blood pressure to dietary salt. Nonconservative mutations in the coding region are extremelyrare and do not explain the variable 11beta‐HSD2 activity. We focused therefore on the 5′‐regulatory region and identified and characterized the first promoter polymorphisms. Trans‐fections of variants G‐209A and G‐126A into SW620 cells reduced promoter activity and affinity for activators nuclear factor 1 (NF1) and Sp1. Chromatin immu‐noprecipitation revealed Sp1, NF1, and glucocorticoid receptor (GR) binding to the HSD11B2 promoter. Dexamethasone induced expression of mRNA and activity of HSD11B2. GR and/or NF1 overexpression increased endogenous HSD11B2 mRNA and activity. GR complexes cooperated with NF1 to activate HSD11B2, an effect diminished in the presence of the G‐209A variant. When compared to salt‐resistant subjects (96), salt‐sensitive volunteers (54) more frequently had the G‐209A variant, higher occurrence of alleles A4/A7 of polymorphic microsatellite marker, and higher urinary ratios of cortisol to cortisone metabolites. First, we conclude that the mechanism of glucocor‐ticoid‐induced HSD11B2 expression is mainly mediated by cooperation between GR and NF1 on the HSD11B2 promoter and, second, that the newly identified promoter variants reduce activity and cooperation of cognate transcription factors, resulting in diminished HSD11B2 transcription, an effect favoring salt sensitivity.—Alikhani‐Koupaei, R., Fouladkou, F., Fustier, P., Cenni, B., Sharma, A.

Psychosocial care by general practitioners--where are the problems? Results of a demonstration project on quality management in psychosocial primary care.

Objective: Since 1987, psychosocial services have been a part of the primary care setting in Germany. In the framework of an eight-center national demonstration program, problems in the diagnosis and therapy of psychosocial problems and psychosomatic disorders were assessed. Methods to improve quality were also implemented. Method: General practitioners (n = 191) from six regions participated in the study. One thousand three hundred and forty-one treatment episodes of patients with predominantly psychosocial symptoms were documented. Differences between psychosocial strain, treatment, and outcome were determined by analyses of variance. Results: Anxiety (62%), depression (51%), and marital/family conflicts (44%) were the most frequent symptoms. Psychosocial treatment was offered more often to those patients who had the highest level of anxiety and depression. Patients with pain and without a psychological attribution to their illnesses were offered less psychosocial treatment and suffered worse results. Partners and family members were rarely integrated into therapy. The procedures employed to improve outcome were quality circles, family-oriented case conferences, consultation services, and collaborative groups. Conclusions: These initial results are promising. A process of internal quality management has been initiated. Some of the physicians still resist documenting the data. Patients with somatic symptoms without psychological attribution may need special psychosocial interventions to improve their outcomes.

Short-term effects of espresso coffee on heart rate variability and blood pressure in habitual and non-habitual coffee consumers – A randomized crossover study

Objective: Coffee is one of the most widely consumed beverages worldwide. Aim of this study was to investigate short-term effects of espresso coffee on heart rate variability (HRV), a marker of vagal activity, in healthy habitual and non-habitual coffee consumers. Methods: Seventy-seven healthy subjects (38 habitual and 39 non-habitual coffee consumers, 74% women, mean age 26.97 ± 6.88 years) took part in three laboratory sessions in a randomized order. In condition 1, subjects consumed espresso; in condition 2, subjects consumed decaffeinated espresso; and in condition 3, subjects consumed warm water. HRV and blood pressure were assessed at rest before and after ingestion of the respective beverage. Results: HRV was significantly increased after consumption of caffeinated espresso, decaffeinated espresso, or water, indicating increased vagal activity in the course of the experiments. In the habitual coffee consumers, the increase in vagally mediated HRV was significantly lower after consumption of decaffeinated espresso compared to caffeinated espresso. Increases of systolic blood pressure were only found in the non-habitual consumers. Conclusion: We found no evidence for specific short-term effects of caffeinated espresso on vagal activity in healthy subjects. Instead, consumption of decaffeinated espresso inhibited vagal activity in habitual consumers. This may be explained by an attempt of the organism to establish a sympathovagal equilibrium comparable to that after caffeine consumption. In the absence of caffeine-induced sympathetic activation, this may have been achieved by relative vagal withdrawal.

Somatic comorbidity in anorexia nervosa: First results of a 21-year follow-up study on female inpatients.

BackgroundAnorexia nervosa is a severe psychosomatic disease with somatic complications in the long-term course and a high mortality rate. Somatic comorbidities independent of anorexia nervosa have rarely been studied, but pose a challenge to clinical practitioners. We investigated somatic comorbidities in an inpatient cohort and compared somatically ill anorexic patients and patients without a somatic comorbidity. In order to evaluate the impact of somatic comorbidity for the long-term course of anorexia nervosa, we monitored survival in a long-term follow-up.MethodOne hundred and sixty-nine female inpatients with anorexia nervosa were treated at the Charité University Medical Centre, Campus Benjamin Franklin, Berlin, between 1979 and 2011. We conducted retrospective analyses using patients medical and psychological records. Information on survival and mortality were required through the local registration office and was available for one hundred patients. The mean follow-up interval for this subgroup was m = 20.9 years (sd = 4.7, min = 13.3, max = 31.6, range = 18.3). We conducted survival analysis using cox regression and included somatic comorbidity in a multivariate model.ResultsN = 41 patients (24.3%) showed a somatic comorbidity, n = 13 patients (7.7%) showed somatic comorbidities related to anorexia nervosa and n = 26 patients (15.4%) showed somatic comorbidities independent of anorexia nervosa, n = 2 patients showed somatic complications related to other psychiatric disorders. Patients with a somatic comorbidity were significantly older (m = 29.5, sd = 10.3 vs m = 25.0, sd = 8.7; p = .006), showed a later anorexia nervosa onset (m = 24.8, sd = 9.9 vs. m = 18.6, sd = 5.1; p < .000) and a longer duration of treatment in our clinic (m = 66.6, sd = 50.3 vs. m = 50.0, sd = 47; p = .05) than inpatients without somatic comorbidity. Out of 100 patients, 9 patients (9%) had died, on average at age of m = 37 years (sd = 9.5). Mortality was more common among inpatients with somatic comorbidity (n = 6, 66.7%) than among inpatients without a somatic disease (n = 3, 33.3%; p = .03). Somatic comorbidity was a significant coefficient in a multivariate survival model (B = 2.32, p = .04).ConclusionSomatic comorbidity seems to be an important factor for anorexia nervosa outcome and should be included in multivariate analyses on the long-term course of anorexia nervosa as an independent variable. Further investigations are needed in order to understand in which way anorexia nervosa and a somatic disease can interact.

Depressive symptoms and heart rate variability in younger women after an acute coronary event

Objectives We investigated associations between depressive symptoms and reduced heart rate variability (HRV) in women aged 30–65 years after an acute coronary event. Background Younger women have an increased mortality after myocardial infarction compared with men of similar age. Depression was hypothesized to contribute to the poor prognosis, possibly mediated by increased susceptibility to arrhythmias. Methods The Stockholm Female Coronary Risk study comprised of 292 women aged 30–65 years who were consecutively admitted for myocardial infarction or unstable angina pectoris during a 3-year period. Depressive symptoms were assessed by means of a 9-item questionnaire. Women with no or only one depressive symptom were classified as low-depression individuals, those with two or more depressive symptoms as high-depression individuals. HRV data were calculated from 24-h ambulatory electrocardiographic recordings 3–6 months after the initial event. Results Reliable HRV data were obtained from 266 patients. Seventy women were low-depression individuals, and 196 women were high-depression individuals. In univariate analyses, the index of standard deviations of R–R intervals, very low-frequency power, low-frequency power and high-frequency power of HRV were lower in the high-depression individuals. After controlling for potential confounders (diabetes, hypertension, systolic blood pressure, body mass index and β-blocker medication), a significant difference between low and high-depression individuals was maintained for all indices except for high-frequency power. Conclusion The presence of two or more depressive symptoms was associated with reduced HRV in a high-risk group of younger women after an acute coronary event.

Attachment style contributes to the outcome of a multimodal lifestyle intervention

Background & AimsThe long-term success of life-style interventions in the treatment of obesity is limited. Although psychological factors have been suggested to modify therapeutic effects, specifically the implications of attachment styles and the patient-therapist relationship have not been examined in detail yet.MethodsThis study included 44 obese patients who participated in a one-year multimodal weight-reduction program. Attachment style was analyzed by the Adult Attachment Prototype Rating (AAPR) inventory and its relation to a one-year weight reduction program was studied. The patient-therapist-relationship was assessed using the Helping Alliance Questionnaire.ResultsAttachment style was secure in 68% of participants and insecure (preoccupied and dismissing) in 32%. Interestingly a significantly higher weight-reduction was found in securely (SAI) compared to insecurely attached individuals (UAI; p < 0.05). This estimation correlated positively also to the quality of helping alliance (p = 0.004).ConclusionsThe frequency of insecure attachment in obese individuals was comparable to that of the normal population. Our data suggest a greater weight-reduction for SAI than for UAI, and the patient-therapist relationship was rated more positively. The conclusion can be drawn that a patients attachment style plays a role in an interdisciplinary treatment program for obesity and has an influence on the effort to lose weight.

Low Anxiety Males Display Higher Degree of Salt Sensitivity, Increased Autonomic Reactivity, and Higher Defensiveness

BACKGROUND Psychological parameters such as heightened anxiety and defensiveness are associated with increased cardiovascular morbidity and mortality. Autonomic dysfunction is considered to be an important pathogenetic pathway. Little research has been done regarding potential links between emotional factors and salt sensitivity. The aim of the present study was to determine whether subjects with different levels of trait anxiety differ in the degree of salt sensitivity and autonomic reactivity to a mental stress task. METHODS Seventy-two young normotensive men were phenotyped for salt sensitivity and underwent a standardized mental stress test and psychological assessment. According to their trait anxiety test scores, they were classified as low-, moderate- or high-anxiety subjects. A measure of defensiveness was used to assess self-deceptive tendencies. RESULTS Low-anxiety subjects displayed a higher degree of salt sensitivity compared to moderate- and high-anxiety subjects (P < 0.001), increased heart rate (HR) and electrodermal responses to the stressor compared to moderate-anxiety subjects (P < 0.01 and P < 0.05 respectively) and elevated levels of self-deception compared to moderate- and high-anxiety subjects (P < 0.001). CONCLUSION Low-anxiety subjects were characterized by a higher degree of salt sensitivity and increased autonomic responsiveness. Defensiveness was also shown to be elevated in this group and might be the underlying psychological trait explaining these findings. Future research on the associations of anxiety and cardiovascular risk should implement measurement of defensiveness in order to identify these subjects at potential risk for cardiovascular disease despite self-reports of low anxiety.
