The clinical impact of mood disorder comorbidity on social anxiety disorder

Background

High comorbidity rates of mood disorders have been reported in patients with social anxiety disorder (SAD). Our study aims to identify the frequency of comorbid Axis I disorders in patients with SAD and to investigate the impact of psychiatric comorbidity on SAD.

Methods

The study included 247 patients with SAD. Thirty eight patients with bipolar depression (SAD-BD), 150 patients with major depressive disorder (SAD-MDD) and 25 patients who do not have any mood disorder comorbidity (SAD-NOMD) were compared.

Results

Around 90% of SAD patients had at least one comorbid disorder. Comorbidity rates of lifetime MDD and BD were 74.5% and 15.4%, respectively. There was no comorbidity in the SAD-NOMD group. Atypical depression, total number of depressive episodes and rate of PTSD comorbidity were higher in SAD-BD than in SAD-MDD. Additionally, OCD comorbidity was higher in SAD-BD than in SAD-NOMD. SAD-MDD group had higher social anxiety severity than SAD-NOMD.

Conclusions

Mood disorder comorbidity might be associated with increased severity and decreased functionality in patients with SAD.     

Mood and anxiety disorders among inpatients of a university hospital in Turkey

Objective

The aim of the study was to assess the prevalence of mood and anxiety disorders among inpatients and the relationship between sociodemographic factors, medical illnesses and treatments.

Methods

In the present study, we selected 650 inpatients from all clinics except psychiatry and pediatrics in a general hospital by a simple random sampling method. Based on the exclusion criteria, 57 patients were excluded. Mood and anxiety disorders were determined by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition.

Results

Of the participants, 226 (37.5%) had a psychiatric disorder, 87 (14.4) had a mood disorder and 146 (24.2%) had an anxiety disorder. The most common specific diagnoses were not otherwise specified as anxiety disorder (9.5%), major depression (8.6%) and generalized anxiety disorder (7.6%). While the overall prevalence was highest in the hematology clinic (60.0%), it was lowest in the clinic of infectious diseases (22.7%). Logistic regression analysis indicated that the independent factors associated with psychiatric disorders were being of the female gender and a personal history of psychiatric disorders.

Conclusions

In conclusion, results of the present study suggest that mood and anxiety disorders were frequently observed among inpatients, particularly in female patients and those with an individual history of psychiatric disorder. Successful treatment of these disorders may positively contribute to the course of the disease in inpatients. However, this assumption should be confirmed by further studies.     

Prevalence of psychiatric disorders in patients with diabetes types 1 and 2

Background

Diabetes mellitus, classified into types 1 and 2, is a chronic disease that shows high comorbidity with psychiatric disorders. Insulin-dependent patients show a higher prevalence of psychiatric disorders than do patients with type 2 diabetes.

Methods

This research involved the participation of 200 subjects divided into 2 groups: 100 patients with diabetes type 1 and 100 patients with diabetes type 2. This study used the Mini International Neuropsychiatric Interview for the identification of psychiatric disorders.

Results

Of the 200 participants, 85 (42.5%) were found to have at least 1 psychiatric disorder. The most prevalent disorders were generalized anxiety disorder (21%), dysthymia (15%), social phobia (7%), current depression (5.5%), lifelong depression (3.5%), panic disorder (2.5%), and risk of suicide (2%). Other disorders with lower prevalence were also identified. The groups showed a statistically significant difference in the presence of dysthymia, current depression, and panic disorder, which were more prevalent in patients with diabetes type 1.

Conclusion

The high prevalence of psychiatric disorders in diabetic patients points to the need for greater investment in appropriate diagnostic evaluation of patients that considers mental issues. The difference identified between the groups shows that preventive measures and therapeutic projects should consider the specific demands of each type of diabetes.     

The prevalence of depression and anxiety disorders in patients with euthyroid Hashimoto’s thyroiditis: a comparative study

Objective

The aim of this study was to examine the current prevalence of major depression and anxiety disorders in patients with euthyroid Hashimoto’s thyroiditis (HT) and euthyroid goiter.

Method

The study sample was formed by consecutive 51 and 45 patients who were admitted to the endocrinology outpatient clinic and diagnosed with euthyroid HT and endemic/nonendemic goiter, respectively, and 68 healthy controls. Current diagnoses of psychiatric disorders were determined using the Structured Clinical Interview for DSM-IV. Beck Depression Inventory and Beck Anxiety Inventory were applied to the participants.

Results

There was a statistically significant difference among the three groups in terms of major depression (P=.001), any mood or anxiety disorder (P=.000), any depressive disorder (P=.020), any anxiety disorder (P=.016) and obsessive–compulsive disorder (OCD) (P=.013). In the HT group, the prevalence of depression (P=.000), OCD (P=.005) and panic disorder (P=.041) was significantly higher than that in the control group. In the goiter group, depression (P=.006), any depressive disorder (P=.03), and any mood or anxiety disorder (P=.000) were significantly common in comparison to the control group. No significant difference was found between the HT and goiter groups.

Conclusions

Euthyroid HT and euthyroid goiter increase predisposition to major depression and anxiety disorders, and thyroid autoimmunity and other thyroid pathologies should be investigated in euthyroid patients with chronic and treatment-resistant complaints.     

Eating disorder symptoms and comorbid psychopathology among male and female veterans

Objective

Eating disorder (ED) symptoms have gone mostly unexamined among veterans. The current study assessed rates of bulimia nervosa (BN) and binge eating disorder (BED) symptoms and diagnoses and their associations with common comorbidities among male and female veterans.

Method

Participants were US military veterans who screened positive for trauma histories and/or a probable Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DSM-IV) posttraumatic stress disorder (PTSD) diagnosis (n= 499). Symptoms of PTSD were assessed using the Clinician-Administered PTSD Scale, and symptoms of EDs, mood, and substance use disorders were assessed using the Structured Clinical Interview for the DSM-IV.

Results

Lifetime rates of BN and BED diagnoses were comparable to civilian populations, and a considerable range of lifetime and current BN and BED symptoms were identified. In multivariate models, PTSD and depression severity were most consistently associated with BN and BED symptom severity, with depression most strongly associated with EDs for women.

Conclusions

Findings highlight the importance of screening for ED symptoms among male and female veterans, particularly those that present with PTSD and depression symptomatology. Future examinations of the temporal order of such relationships and the degree to which ED symptoms and associated symptoms impact veteran functioning are warranted.     

Hemoglobin levels in persons with depressive and/or anxiety disorders

Objective

Both low and high hemoglobin levels lead to more physical diseases, and both are linked to mortality. Low hemoglobin, often classified as anemia, has also been linked to more depressive symptoms, but whether both hemoglobin extremes are associated with depressive disorder and potentially also with anxiety disorder has not been examined before. This study examines to which extent hemoglobin levels are associated with depression and anxiety disorders in a large cohort.

Methods

The study sample consisted of 2920 persons from the Netherlands Study of Depression and Anxiety. Hemoglobin levels were determined after venipuncture. Depressive and anxiety disorders were determined according to a DSM-IV-based psychiatric interview. Clinical psychiatric characteristics included the severity of depression and anxiety, the duration of symptoms, the age of onset and the antidepressant use.

Results

Higher hemoglobin levels were found in those with current depressive and/or anxiety disorders after sociodemographic adjustment and both higher, and lower hemoglobin levels were found in persons with higher depression and anxiety severity. However, after full adjustment for sociodemographics, disease indicators and lifestyle, associations were no longer significant.

Conclusions

This cohort study showed that there is no independent association between depressive and/or anxiety disorders and hemoglobin levels or anemia status.     

Is interictal EEG activity a biomarker for mood disorders in temporal lobe epilepsy?

Objective

Psychiatric comorbidities are frequent in temporal lobe epilepsy (TLE), and symptoms of these comorbidities may be related to epilepsy activity. Here we evaluated interictal EEG activity in TLE patients with or without psychiatric comorbidities.

Methods

A cohort study of 78 patients with TLE, with evaluation of wake/sleep interictal scalp EEG. All subjects were submitted to a psychiatric structured clinical interview (SCID) for the diagnosis of lifetime psychiatric comorbidities. Three major diagnostic categories were studied: mood disorders, anxiety disorders, and psychosis. We then evaluated differences in interictal EEG activity between patients with and without these psychiatric comorbidities.

Results

Infrequent EEG interictal spikes, defined as less than one event per minute, were significantly associated with mood disorders in TLE (p = 0.02).

Conclusions

Low intensity seizure disorder has been associated with a decrease in interictal EEG discharges and with an increase in psychiatric symptoms in TLE, a phenomenon known as forced normalization. In our study, we observed a low interictal spike frequency on EEG in TLE patients with mood disorders.

Significance

A low spike index might be a neurophysiological marker for depression in temporal lobe epilepsy.     

Rapid relapse in depression following initialization of oral contraception with ethinyl estradiol and chlormadinone acetate

Objective

Female sexual hormones (estrogens and gestagens) may affect neurocognitive functioning and mood. Thus, the use of oral hormonal contraceptives (OHC) bears the risk of psychiatric adverse drug reactions such as depression and psychosis. However, the available empiric evidence regarding this connection is conflicting, and, moreover, female sex hormones seem to feature also mood-stabilizing and antidepressive effects. Hence, individual susceptibility factors and preparation-specific pharmacologic properties might play a pivotal role in the development of mood disturbances related to OHC. Single case reports provide empiric data for further systematic approaches.

Methods

A clinical case is presented and discussed.

Results

A 36-year-old female patient with recurrent major depressive disorder developed rapid relapse in depression after initialization of OHC with ethinyl estradiol 30 μg/chlormadinone acetate 2 mg. This OHC combination was described to particularly feature positive effects on depressive mood.

Conclusions

OHC may induce serious mood disturbances and should be administered with care, particularly in patients with affective disorders.     

Point prevalence and correlates of depression in a national community sample with multiple sclerosis

Objective

The prevalence of depression in multiple sclerosis (MS) is known to be elevated, but nearly all available studies have estimated period prevalence. The objective of this study was to estimate the point prevalence of depression in a representative community sample using the Patient Health Questionnaire, Brief (PHQ-9).

Methods

The data source for this study was the Survey of Living with Neurological Conditions in Canada, which was derived from a representative sample of household residents.

Results

The sample included 630 respondents with MS. With application of the standard PHQ-9 cut point (10 +), the prevalence of depression was 26.0% (95% confidence interval 18.9%–33.0%). Depressed subjects had lower quality of life; an increased frequency of suicidal ideation; and more often reported a negative disease course, high stress, low social support and stigmatization.

Conclusions

This study adds to the existing literature by providing point prevalence data: in any 2-week period, about one quarter of community residents with MS experience substantial levels of depressive symptoms.     

The TAS-20 more likely measures negative affects rather than alexithymia itself in patients with major depression,panic disorder,eating disorders and substance use disorders

Background

This study evaluates whether the difference in Toronto Alexithymia Scale-20 item (TAS-20) between patients with major depression (MD), panic disorder (PD), eating disorders (ED), and substance use disorders (SUD) and healthy controls persisted after controlling for the severity of anxiety and depression.

Methods

Thirty-eight patients with MD, 58 with PD, 52 with ED, and 30 with SUD and 78 healthy controls (C) completed the TAS-20, the Hamilton Rating Scale for Anxiety (Ham-A), the Hamilton Rating Scale for Depression (Ham-D).

Results

The differences in TAS-20 scores observed between patient groups, regardless of the type of their disorders, and controls disappeared after controlling for the effect of anxiety and depression severity. In contrast, the differences in severity of anxiety and depression between patients and controls were still present, after excluding the effect of alexithymic levels.

Conclusions

Our data suggest that alexithymic levels, as measured by the TAS-20, are modulated by the severity of symptoms, supporting the view that alexithymia can represent a state phenomenon in patients with MD, PD, ED and SUD, because the TAS-20 seems overly sensitive to a general distress syndrome, and it is more likely to measure negative affects rather than alexithymia itself.     

Electrodermal hyporeactivity as a trait marker for suicidal propensity in uni- and bipolar depression

Background

A meta-analysis of studies investigating electrodermal activity in depressed patients, suggested that electrodermal hyporeactivity is sensitive and specific for suicide.

Aims

To confirm this finding and to study electrodermal hyporeactivity relative to type and severity of depression, trait anxiety, its stability and independence of depressive state.

Method

Depressed inpatients (n = 783) were tested for habituation of electrodermal responses and clinically assessed using the Beck Depression Inventory (BDI) and the STAI-Trait scale for trait anxiety.

Results

The high sensitivity and raw specificity of electrodermal hyporeactivity for suicide were confirmed. Its prevalence was highest in bipolar disorders and was independent of severity of depression, trait anxiety, gender and age. Hyporeactivity was stable, while reactivity changed into hyporeactivity in a later depressive episode.

Conclusions

The findings support the hypothesis that electrodermal hyporeactivity is a trait marker for suicidal propensity in depression.     

Do psychiatric disorders continue during pregnancy in women with hyperemesis gravidarum: a prospective study

Objective

We aimed to determine Axis I psychiatric disorders in women with hyperemesis gravidarum (HG) and to follow up the course of psychiatric disorder and its association with nausea and vomiting (NV) during pregnancy.

Methods

The study sample was composed of 47 patients with HG. Psychiatric interviews were conducted using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID-I). Other psychiatric interviews were performed in the second and third trimesters. On each visit, the subjects completed the Beck Depression Inventory and the Beck Anxiety Inventory.

Results

The prevalence of any anxiety disorder was 25.5%, and the prevalence of any mood disorder was 14.9% in women with HG in the first trimester. Psychiatric disorders continued throughout the pregnancy in two thirds of the women who had HG and a psychiatric diagnosis. Any SCID diagnosis in the first trimester was higher in women whose NV had partially resolved than in women whose NV had fully resolved (P< .05).

Conclusion

The present studies suggest that psychiatric disorders may play a significant role in the etiology of HG. Our findings presented a potential connection between HG and anxiety disorders and major depressive disorder. Additionally, the NV symptoms in women with HG and a psychiatric disorder may persist during pregnancy.     

Influence of psychiatric disorders on surgical outcomes and care resource use in Japan

Objective

The aim of this study was to quantify the effects of psychiatric disorders on major surgery outcomes and care resource use.

Methods

This study adopted a retrospective cohort study design. The samples consisted of hospital stays. Subjects were patients who had undergone major surgery. We used multilevel regression analysis to quantify the influence of psychiatric disorders on major surgery outcomes and care resource use.

Results

The total number of hospital stays included in the study was 5569, of which 250 were patients with psychiatric disorders. Compared with those without psychiatric disorders, those with schizophrenia had a significantly higher risk of complications, and those with neurotic disorder tended to have fewer complications. Total cost was significantly higher for those with schizophrenia and mood disorder and significantly lower in those with neurotic disorder. Lengths of stay were significantly longer for those with schizophrenia and mood disorder but not for those with neurotic disorder. Post-surgical mortality was equivalent among those with any psychiatric disorder and among those without a psychiatric disorder.

Conclusion

The study revealed that surgical outcomes and care resource use are differentiated by psychiatric disorders.     

Can patterns of alcohol use disorder in young adulthood help explain gender differences in depression?

Objective

To test whether gender differences in the prevalence of major depressive disorder differ by longitudinal patterns of alcohol use disorder symptoms.

Method

Data are from a prospective longitudinal study examining a broad range of mental health and substance use problems. A gender-balanced sample of 808 participants was interviewed at ages 21, 24, 27, and 30. The sample was divided into subgroups corresponding to longitudinal patterns of alcohol use disorder derived from latent class growth analysis.

Results

Four patterns of alcohol use disorder symptoms were identified: A “low disorder symptom” group, a “decreaser” group, an “increaser” group, and a “chronic disorder symptom” group. Rates of depression were significantly higher for females only among those with a pattern of chronic or decreasing alcohol disorder symptoms.

Conclusions

Elevated rates of depression among females in young adulthood may depend on patterns of co-occurring alcohol disorder symptoms. Practitioners should pay particular attention to signs of chronic alcohol use disorders and associated risks for depression among young adult women.     

Peptic ulcer disease and mental illnesses

Objective

We evaluated the association between self-reported doctor-diagnosed peptic ulcer disease (PUD) and mental disorders in a representative cross-sectional study conducted in 2010 in Singapore.

Method

The sample comprised 6616 community-dwelling individuals. Participants were asked about a previous history of doctor-diagnosed PUD. Assessment of mental disorders was performed using the World Mental Health Composite International Diagnostic Interview version 3.0. Quality of life was assessed using the EuroQoL 5D.

Results

The weighted prevalence of PUD was 1.58% (95% CI=1.13–2.02). In adjusted analyses, PUD was more common among people with anxiety disorders [obsessive compulsive disorders (OR 4.22, 95% CI 1.59–11.21), Generalized Anxiety Disorders (OR 9.25, 95% CI 2.43-35.17), any anxiety disorders (OR 4.41, 95% CI 1.82-10.61)] and with any mood disorders (OR 2.66, 95% CI 1.08-6.53). PUD was associated with alcohol abuse and alcohol dependence, but not with smoking or nicotine dependence. Adjustment for nicotine and alcohol use attenuated the association of mood disorders with PUD, but not that of anxiety disorders. PUD was associated with reduced quality of life as measured on EuroQoL 5D, with further reduction in those with concomitant mental disorders.

Conclusion

PUD was associated with anxiety disorders, and this association is not attenuated with adjustment for nicotine dependence or alcohol use disorder.     

Prevalence of psychiatric disorders in patients with polycystic ovary syndrome

Objective

To investigate the prevalence of psychiatric disorders among women in ambulatory treatment for polycystic ovary syndrome (PCOS) and to correlate its clinical and demographic aspects with mental disorders.

Methodology

Seventy-two patients in ambulatory treatment at the Endocrinal and Gynaecological Institute of the Federal University of Rio de Janeiro were evaluated using Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition criteria by means of MINI (Mini International Neuropsychiatric Interview, version 4.4). Polycystic ovary syndrome was confirmed according to the ultrasonographic criteria of Adams and by clinical parameters.

Results

Forty-one patients (57%) presented at least one psychiatric diagnosis. Among them, the prevalence of mood disorder reached 78%. The most prevalent diagnostics were major depression (26.4%) and bipolar disorder (11.1%).

Conclusion

A high prevalence of mental disorders was observed, especially major depression and bipolar disorder. The data obtained regarding the relationship between PCOS and mood disorders in a Brazilian sample is in accordance with recent research findings in the same area.     

Psychological Characteristics of Problem Gamblers With and Without Mood Disorder

Objective:

Problem and pathological gamblers are significantly more likely to experience mood disorders, compared with the general population. Our study examined the relation of psychological characteristics (personality, trait impulsiveness, and gambling motives) to current co-occurring mood disorder (major depression and dysthymia) status among problem and pathological gamblers.

Method:

Problem and pathological gamblers (N = 150) underwent a clinical interview to assess current co-occurring mood disorders; participants completed measures of problem gambling severity, personality, impulsiveness, and gambling motives.

Results:

Problem and pathological gamblers with a current co-occurring mood disorder were more likely to be female, older, and to report higher lifetime and past-year gambling severity. A co-occurring mood disorder was associated with higher personality scores for alienation and stress reaction, lower scores for well-being, social closeness, and control, as well as higher impulsiveness scores for urgency and lack of premeditation, and lower sensation seeking scores. Participants with a co-occurring mood disorder also reported higher coping motives for gambling. Multivariate logistic regression analyses demonstrated that personality factors (lower social closeness and higher alienation) contributed to the greatest likelihood of being diagnosed with a co-occurring mood disorder.

Conclusions:

Mood disorders frequently co-occur with problem and pathological gambling, and they are associated with greater gambling severity. These findings highlight that interpersonal facets of personality contribute substantially to co-occurring mood disorder status. Implications for treatment will be discussed.     

Comorbid atypical depression in borderline personality disorder is common and correlated with anxiety-related psychopathology

Background

The core features of borderline personality disorder (BPD) are affective instability, unstable relationships and identity disturbance. Axis I comorbidities are frequent, in particular affective disorders. The concept of atypical depression is complex and often underestimated. The purpose of the study was to investigate the comorbidity of atypical depression in borderline patients regarding anxiety-related psychopathology and interpersonal problems.

Methods

Sixty patients with BPD were assessed with the Structured Clinical Interviews for DSM-IV Axis I and II Disorders (SCID I, SCID II) as well as the Atypical Depression Diagnostic Scale (ADDS). Additionally, patients completed a questionnaire (SCL-90-R, BDI, STAI, STAXI, IIP-C).

Results

Forty-five BPD patients (81.8%) had a comorbid affective disorder of which 15 (27.3%) were diagnosed with an atypical depression.In comparison to patients with major depressive disorder or no comorbid depression, patients with atypical depression showed significant higher scores in psychopathological symptoms regarding anxiety and global severity as well as interpersonal problems.

Conclusions

The presence of atypical depression in borderline patients is correlated with psychopathology, anxiety, and interpersonal problems and seems to be of clinical importance for personalized treatment decisions.     

Prevalence and determinants of depression in Mexican patients with Parkinson's disease

Objective

To assess the prevalence and associated factors of depression in a Mexican Parkinson's disease (PD) population.

Background

Depressive symptoms are frequent in PD and have been recognized as a major determinant of quality of life. Only two previous studies have partially addressed depression in Mexican PD patients.

Methods

One hundred forty-seven non-demented PD patients were recruited at the movement disorder specialist clinic at the National Institute of Neurology and Neurosurgery, Mexico City. The following sociodemographic variables were collected: gender, age, age at onset, disease duration and disease severity in terms of Hoehn and Yahr stage. PDQ-8, NMSQuest and Beck Depression Inventory (BDI) were applied to all participants.

Results

One hundred forty-seven patients were included (49.7% female). The mean age of the sample was 62.1 ± 11.7 years, the mean age at diagnosis was 55.8 ± 12.3 and the mean duration of the disease was 6.3 ± 5 years. A total of 49 (33.3%) patients were diagnosed with current depression. Depressed patients also scored higher in the NMSQuest even when depression/anxiety items were excluded. Differences were found in gender, UPDRS III score and HY stage, but after the logistic regression analysis was performed only the NMSQuest score and low education remained as statistically significant factors for depression in Mexican PD patients.

Conclusions

Depression prevalence in PD Mexican patients is similar to other international reports. The main associated factor was the presence of non-motor symptoms.     

Prevalence and clinical correlates of alcohol use disorders among bipolar disorder patients: Results from the Brazilian Bipolar Research Network

Objectives

To investigate prevalence rates and clinical correlates of alcohol use disorders (AUD) among bipolar disorder (BD) patients in a large sample from the Brazilian Bipolar Research Network.

Methods

Four hundred and eighty-three DSM-IV BD patients, divided according to the presence or absence of a lifetime AUD diagnosis (BD-AUD vs. BD-nonAUD), were included. Demographic and clinical characteristics of these two groups were compared. Logistic regression was performed to identify which characteristics were most strongly associated with a lifetime AUD diagnosis.

Results

Nearly 23% presented a lifetime AUD diagnosis. BD-AUD patients were more likely to be male, to present rapid cycling, post-traumatic stress disorder (PTSD), anorexia, other substance use disorders (SUD), family history of SUD, any substance misuse during the first mood episode, history of psychosis, suicide attempts, and younger age at onset of illness than BD-nonAUD patients. Logistic regression showed that the variables most strongly associated with a lifetime AUD diagnosis were SUD (non-alcohol), any substance misuse during the first mood episode, PTSD, male gender, suicide attempt, family history of SUD, and younger age at onset of BD.

Conclusions

BD-AUD patients begin their mood disorder earlier and present more suicidal behaviors than BD-nonAUD patients. Personal and family history of SUD may be good predictors of comorbid AUD among BD patients. These variables are easily assessed in the clinical setting and may help to identify a particularly severe subgroup of BD patients.
