Overlap of anxiety and depression complicates diagnosis and renders treatment challenging. A vital step in treatment of such comorbidity is careful and comprehensive diagnostic assessment. We attempt to explain various psychosocial and pharmacological approaches for treatment of comorbid anxiety and depression. For the psychosocial component, we focus only on generalized anxiety disorder based on the following theoretical models:(1) "the avoidance model";(2) "the intolerance of uncertainty model";(3) "the meta-cognitive model";(4) "the emotion dysregulation model"; and(5) "the acceptance based model". For depression, the following theoretical models are explicated:(1) "the cognitive model";(2) "the behavioral activation model"; and(3) "the interpersonal model". Integration of these approaches is suggested. The treatment of comorbid anxiety and depression necessitates specific psychopharmacological adjustments as compared to treating either condition alone. Serotonin reuptake inhibitors are considered first-line treatment in uncomplicated depression comorbid with a spectrum of anxiety disorders. Short-acting benzodiazepines(BZDs) are an important "bridging strategy" to address an acute anxiety component. In patients with comorbid substance abuse, avoidance of BZDs is recommended and we advise using an atypical antipsychotic in lieu of BZDs. For mixed anxiety and depression comorbid with bipolar disorder, we recommend augmentation of an antidepressant with either lamotrigine or an atypical agent. Combination and augmentation therapies in the treatment of comorbid conditions vis-à-vis monotherapy may be necessary for positive outcomes. Combination therapy with tricyclic antidepressants, gabapentin and selective serotonin/norepinephrine reuptake inhibitors(e.g., duloxetine) are specifically useful for comorbid chronic pain syndromes. Aripiprazole, quetiapine, risperidone and other novel atypical agents may be effective as augmentations. For treatment-resistant patients, we recommend a "stacking approach" not dissimilar from treatment of hypertension In conclusion, we delineate a comprehensive approach comprising integration of various psychosocial approaches and incremental pharmacological interventions entailing bridging strategies, augmentation therapies and ultimately stacking approaches towards effectively treating comorbid anxiety and depression.展开更多

METHODS: One hundred and fifty-six cases of both sexes with cancers of the digestive tract admitted between March 2001 and February 2004 in the Department of Medical Oncology, First Affiliated Hospital of Xi'an Jiaotong University were randomly enrolled in the study. Depressive and anxiety disorder diagnoses were assessed by using the Structured Clinical Interview for DSM-IV. All adult patients were evaluated with the Hamilton depressive scale (HAMD, the 24-item version), the Hamilton anxiety scale (HAMA, a modified 14-item version), quality of life questionnaire-core 30 (QLQ-C30), social support rating scale (SSRS), simple coping style questionnaire (SCSQ), and other questionnaires, respectively. In terms of HAMD ≥ 20 and HAMA ≥ 14, the patients were categorized, including CAD (n = 31) in group A, anxiety disorder (n = 23) in group B, depressive disorder (n = 37) in group C, and non-disorder (n = 65) in group D. Immunological parameters such as T-lymphocyte subsets and natural killer (NK) cell activities in peripheral blood were determined and compared among the four groups. RESULTS: The incidence of CAD was 21.15% in patients with digestive tract cancers. The average scores of social support was 43.67±7.05 for 156 cases, active coping 20.34±7.33, and passive coping 9.55±5.51. Compared with group D, subjective support was enhanced slightly in group A, but social support, objective support, and utilization of support reduced, especially utilization of support with significance (6.16 vs7.80, P<0.05); total scores of active coping decreased, while passive coping reversed; granulocytes proliferated, monocytes declined, and lymphocytes declined significantly (32.87 vs 34.00, P<0.05); moreover, the percentage of CD3, CD4, CD8 and CD56 in T lymphocyte subsets was in lower level, respectively, and CD56 showed a significant decline in group A (26.02 vs 32.20, P<0.05), however, CD4/CD8 ratio increased. Physical function, role function, fatigue, sleeplessness and constipation had significant changes among different groups by one-way ANOVA, and group A was in poor QOL. It revealed that global health-related quality of life (QL) were positively correlated with active coping and CD56; CAD was negatively correlated with QL, active coping and CD56. Furthermore, the step-wise regression analysis suggested that utilization of support, CD56, active coping, fatigue, sleeplessness and depression were significant factors contributing to QOL. CONCLUSION: CAD, which can impair QOL and cellular immunity, occurs with a higher incidence in patients with digestive tract cancers. Hence, it is essential to improve mental health for them with specifically tailored interventions.展开更多

The study employs the Structure of Temperament Questionnaire Compact (STQ 77), whose 12 scales assess the energetic, lability and sensitivity aspects of behavior in the physical, social, mental and emotional domains. The STQ 77 was administered to 86 patients with Major Depression, 85 patients with an anxiety disorder, 43 patients with comorbid depression and anxiety, and 71 subjects without depression or anxiety disorder all presenting to a private outpatient clinical practice. Results: 1) Depression was associated with self-reports of increased impulsivity and rigidity of behavior;2) Depressed patients reported significantly lower physical energy, tempo of physical activity and plasticity of behavior. The presence of comorbid anxiety further worsened these effects;3) The ability to sustain attention on a mental task and to learn new information was lower in depressed patients than in other groups. Conclusions: comorbid depression and anxiety might be associates, decreasing adaptivity and the self-regulatory balance of behavior, leading to the de- velopment of extremes in behavioral reactivity (impulsivity and rigidity).展开更多

This study examined 293 patients with age between 20 and 60 at first visit on the outpatient clinic of psychiatry by the section of social phobia of M.I.N.I. and DSM-IV. After that, 10 patients with both SAD out of 16 patients (trial recruited) completed 12 weeks of treatment with paroxetine. Among 63 patients with 4 points and 40 patients with 3 points on the M.I.N.I., 21 patients (33%) and 16 patients (40%) were diagnosed as SAD on DSM-IV criteria, respectively. Together, 37 patients (12.6%) were diagnosed as SAD out of the 293 outpatients. Among 37 patients with SAD, 23 patients (62%) had comorbid depression. As for 10 patients after treatment with paroxetine, 8 patients improved from the point of recovery of depression (HAM-D scores below 10), whereas only 4 patients improved from the point of recovery of social phobia (L-SAS scores below 30). Three points as well as 4 points on the M.I.N.I. is meaningful for the diagnosis of SAD. For a while, paroxetine exerted less beneficial effects on SAD rather than on depression.展开更多

Several studies reported high rates of depression and anxiety particularly for specific dermatological disorders such as psoriasis and acne. Aim: The aim of this study was to compare the rates of psychiatric symptoms in patients with psoriasis, acne, vitiligo, and eczema versus patients who had other dermatological conditions;and to compare each dermatological group versus healthy control subjects. Methods: This prospective cross-sectional study was conducted in dermatology outpatient clinics in Khartoum. Hospital Anxiety and Depression Scale (HADS) was used to assess symptoms of anxiety (HADS-A) and depression (HADS-D). ICD-10 criteria were used for clinical psychiatric diagnosis. Tabulated results were analyzed using Chi-square test. Significance was set at P < 0.05. Results: HADS-D scores above the cut off points were significantly higher in patients with psoriasis (P = 0.0062), vitiligo (P = 0.0054), acne (P = 0.0103) and eczema (P = 0.0359) compared with healthy subjects. Similarly, HADS-A scores above the cut off points were significantly higher in patients with psoriasis (P < 0. 0.0001), vitiligo (P = 0.0001), acne (P = 0.0143) and eczema (P = 0.0281) compared with healthy subjects. No significant difference between the control group and patients with other dermatologic conditions regarding both HADS-D and HADS-A scores. Using ICD-10 criteria for clinical psychiatric diagnoses indicated that 52.3% of dermatology patients had an associated ICD-10 diagnosis;most commonly anxiety disorders (28.6%), and depression (21.9%). ICD-10 diagnoses of anxiety disorders included: OCD (13.3%) generalized anxiety disorder (5.7%), panic disorder (4.8%), phobic anxiety disorder (3.8%) and post-traumatic stress disorder (0.95%). Conclusion: Dermatological conditions are associated with high rates of psychiatric comorbidity. Screening for anxiety and depressive symptoms may be helpful for early diagnosis and management of associated psychiatric symptoms.展开更多

文摘Background:Depression and anxiety have been correlated with elevated risks for quality-of-life (QOL),adverse outcomes,and medical expenditure in patients with acute coronary syndrome (ACS).However,the relevant data are lacking for Chinese ACS populations,especially regarding different effects of major depression,anxiety,and comorbidity.The objective of this study was to evaluate the dynamic changes of depression and/or anxiety over 12 months and examine the effects of depression,anxiety,and comorbidity on QOL,adverse outcomes,and medical expenditure in Chinese patients with ACS.Methods:For this prospective longitudinal study,a total of 647 patients with ACS were recruited from North China between January 2013 and June 2015.Among them,531 patients (82.1%) completed 12-month follow-ups.Logistic regression model was utilized for analyzing the association of baseline major depression,anxiety,and comorbidity with 12-month all-cause mortality,cardiovascular events,QOL,and health expenditure.Results:During a follow-up period of 12 months,7.3% experienced non-fatal myocardial infarction (MI) and 35.8% cardiac rehospitalization.Baseline comorbidity,rather than major depression/anxiety,strongly predicted poor 12-month QOL as measured by short-form health survey-12 (odds ratio [OR]:1.77,95% confidence interval [CI]:1.22–2.52,P = 0.003).Regarding 12-month non-fatal MI and cardiac re-hospitalization,baseline anxiety (OR:2.83,95% CI:1.33–5.89,P<0.01;OR:4.47,95% CI:1.50–13.00,P<0.01),major depression (OR:2.58,95% CI:1.02–6.15,P<0.05;OR:5.22,95% CI:1.42–17.57,P<0.03),and comorbidity (OR:6.33,95% CI:2.96–13.79,P<0.0001,OR:14.08,95% CI:4.99–41.66,P<0.0001) were all independent predictors,and comorbidity had the highest predictive value.Number of re-hospitalization stay,admission frequency within 12 months and medical expenditure within 2 months were the highest in patients with ACS with comorbidity.Conclusions:Major depression and anxiety may predict 12-month non-fatal MI and cardiac re-hospitalization.However,comorbidity has the highest predictive value with greater medical expenditure and worse QOL in Chinese patients with ACS.And depression with comorbid anxiety may be a new target of mood status in patients with ACS.
文摘Background: Dermatological conditions can be associated with high psychiatric comorbidity. Several studies reported high rates of depression and anxiety particularly for specific dermatological disorders such as psoriasis and acne. Aim: The aim of this study was to compare the rates of psychiatric symptoms in patients with psoriasis, acne, vitiligo, and eczema versus patients who had other dermatological conditions;and to compare each dermatological group versus healthy control subjects. Methods: This prospective cross-sectional study was conducted in dermatology outpatient clinics in Khartoum. Hospital Anxiety and Depression Scale (HADS) was used to assess symptoms of anxiety (HADS-A) and depression (HADS-D). ICD-10 criteria were used for clinical psychiatric diagnosis. Tabulated results were analyzed using Chi-square test. Significance was set at P < 0.05. Results: HADS-D scores above the cut off points were significantly higher in patients with psoriasis (P = 0.0062), vitiligo (P = 0.0054), acne (P = 0.0103) and eczema (P = 0.0359) compared with healthy subjects. Similarly, HADS-A scores above the cut off points were significantly higher in patients with psoriasis (P < 0. 0.0001), vitiligo (P = 0.0001), acne (P = 0.0143) and eczema (P = 0.0281) compared with healthy subjects. No significant difference between the control group and patients with other dermatologic conditions regarding both HADS-D and HADS-A scores. Using ICD-10 criteria for clinical psychiatric diagnoses indicated that 52.3% of dermatology patients had an associated ICD-10 diagnosis;most commonly anxiety disorders (28.6%), and depression (21.9%). ICD-10 diagnoses of anxiety disorders included: OCD (13.3%) generalized anxiety disorder (5.7%), panic disorder (4.8%), phobic anxiety disorder (3.8%) and post-traumatic stress disorder (0.95%). Conclusion: Dermatological conditions are associated with high rates of psychiatric comorbidity. Screening for anxiety and depressive symptoms may be helpful for early diagnosis and management of associated psychiatric symptoms.
文摘目的探讨脑卒中后抑郁-焦虑共病(post-stroke anxiety combined with depression,PSCAD)患者合用安神合剂与黛力新治疗对其神经功能缺损、负性心理及不良反应的影响。方法选取2019年8月—2021年5月医院收治PSCAD患者146例,随机数字表法分对照组及观察组,各73例。对照组予以黛力新治疗,观察组在对照组基础之上联用安神合剂;比较治疗前与治疗4周后两组中医证候相关积分,酶联免疫分析仪检测血清5-羟色胺(5-hydroxytryptamine,5-HT)、盐酸多巴胺(Dopamine hydrochloride,DA)以及去甲肾上腺素(Norepinephrine,NE)水平,美国国立卫生研究院卒中量表(National Institutes of Health Stroke Scale,NIHSS)评估神经功能缺损现象,选取特质焦虑分量表(Trait anxiety invento⁃ry,T-AI)、状态焦虑分量表(S-AI)和汉密尔顿抑郁量表与(Hamilton Depression Scale,HAMD)进行负性心理评估;比较两组治疗后不良反应的发生率。结果治疗后,观察组中医症候相关积分皆明显优于对照组(P<0.05);治疗后,观察组血清5-HT、DA及NE水平显著高于对照组,观察组NIHSS评分明显低于对照组(P<0.05);治疗后,观察组T-AI、S-AI和HAMD评分皆明显低于对照组(P<0.05)。观察组不良反应发生率低于对照组,但差异不存在统计学意义(P>0.05)。结论安神合剂与黛力新联用改善PSCAD患者神经功能缺损状况,有效调节负性心理,不增加不良反应发生率。
