Depression and suicidal ideation in dermatology patients with acne, alopecia areata, atopic dermatitis and psoriasis

We examined the prevalence of depression (measured by the Carroll Rating Scale for Depression, CRSD), wishes to be dead and acute suicidal ideation among 480 patients with dermatological disorders that may be cosmetically disfiguring, i.e. non‐cystic facial acne (n = 72; 5.6% suicidal ideation), alopecia areata (n = 45; 0% suicidal ideation), atopic dermatitis (n = 146; 2.1% suicidal ideation) and psoriasis (79 outpatients, 2.5% suicidal ideation and 138 inpatients, 7.2% suicidal ideation). Analysis of variance revealed that the severely affected psoriasis inpatients (mean ± SD total body surface area affected: 52 ± 23.4%) had the highest (P < 0.05) CRSD score, followed by the patients with mild to moderate acne; both scores were in the range for clinical depression (CRSD score > 10). The 5.6–7.2% prevalence of active suicidal ideation among the psoriasis and acne patients was higher than the 2.4–3.3% prevalence reported among general medical patients. Our findings highlight the importance of recognizing psychiatric comorbidity, especially depression, among dermatology patients and indicate that in some instances even clinically mild to moderate disease such as non‐cystic facial acne can be associated with significant depression and suicidal ideation.

Brain activation during script-driven imagery induced dissociative responses in PTSD: a functional magnetic resonance imaging investigation

BACKGROUND The goal of this study was to examine the neuronal circuitry underlying dissociative responses to traumatic script-driven imagery in sexual-abuse-related posttraumatic stress disorder (PTSD). Pilot studies in our laboratory have shown that PTSD patients had very different responses to traumatic script-driven imagery. Approximately 70% of patients relived their traumatic experience and showed an increase in heart rate while recalling the traumatic memory. The other 30% of patients had a dissociative response with no concomitant increase in heart rate. This article focuses on the latter group. METHODS The neuronal circuitry underlying dissociative responses in PTSD was studied using the traumatic script-driven symptom provocation paradigm adapted to functional magnetic resonance imaging (fMRI) at a 4 Tesla field strength in 7 subjects with sexual-abuse-related PTSD and 10 control subjects. RESULTS Compared with control subjects, PTSD patients in a dissociative state showed more activation in the superior and middle temporal gyri (BA 38), the inferior frontal gyrus (BA 47), the occipital lobe (BA 19), the parietal lobe (BA 7), the medial frontal gyrus (BA 10), the medial cortex (BA 9), and the anterior cingulate gyrus (BA 24 and 32). CONCLUSIONS These findings suggest that prefrontal and limbic structures underlie dissociative responses in PTSD. Differences observed clinically, psychophysiologically, and neurobiologically between patients who respond to traumatic script-driven imagery with dissociative versus nondissociative responses may suggest different neuronal mechanisms underlying these two distinct reactions.

Depression modulates pruritus perception: A study of pruritus in psoriasis, atopic dermatitis, and chronic idiopathic urticaria

&NA; Pruritus, or itching, is the most common symptom of dermatologic disease. Psychologic factors can affect pruritus, and in an earlier study of inpatients with moderate to severe psoriasis, we observed that the degree of depressive psychopathology directly correlated with pruritus severity. In this study we investigated the relation between pruritus and depression among a group of patients (N = 252) with a wide range of pruritic skin disorders, including outpatients with mild to moderate psoriasis (N = 77), atopic dermatitis (N = 143) and chronic idiopathic urticaria (N = 32). All patients self‐rated the severity of their pruritus on a 10‐point scale and completed a battery of psychologic ratings, including the Carroll Rating Scale for Depression (CRSD). We observed a direct correlation (Pearsons r = .34, p < .0001) between pruritus severity and the CRSD score. The correlations between pruritus severity and CRSD scores for each individual diagnostic group were as follows: psoriasis: Pearsons r = .32, p = .004; atopic dermatitis: Pearsons r = .21, p = .013; and chronic idiopathic urticaria: Pearsons r = .34, p = .06. When the subjects with pruritus scores less than 5.5 were compared with subjects with pruritus scores greater than 5.5, significant differences (p < .05) in depression scores were found for all three dermatoses by the Mann‐Whitney U test. The depressed clinical state may reduce the threshold for pruritus.

Recall of emotional states in posttraumatic stress disorder: an fMRI investigation

BACKGROUND The goal of this study was to examine the neuronal circuitry underlying different emotional states (neutral, sad, anxious, and traumatic) in posttraumatic stress disorder (PTSD) in traumatized subjects versus traumatized subjects without PTSD. METHODS Traumatized subjects with (n = 10) and without (n = 10) PTSD were studied using the script-driven symptom provocation paradigm adapted to functional magnetic resonance imaging (fMRI) at a 4 Tesla field strength. RESULTS Compared to the trauma-exposed comparison group, PTSD subjects showed significantly less activation of the thalamus and the anterior cingulate gyrus (area 32) in all three emotional states (sad, anxious, and traumatic). CONCLUSION These findings suggest thalamic and anterior cingulate dysfunction in the recollection of traumatic as well as other negative events. Thalamic and anterior cingulate dysfunction may underlie emotion dysregulation often observed clinically in PTSD.

Psychodermatology: An update

It has been estimated that in at least one third of dermatology patients, effective management of the skin disorder involves consideration of associated emotional factors. This article provides an overview of psychodermatology with a focus on the more recent literature and an emphasis on the clinical aspects and psychologic therapies for (1) cutaneous associations of psychiatric disorders and (2) psychiatric associations of certain cutaneous disorders that are known to be influenced by psychosomatic factors. This article also provides an update on the use of psychotropic drugs (i.e., the antianxiety, antidepressant, and antipsychotic agents) for the treatment of mental disorders that occur in conjunction with cutaneous conditions. Some of their other pharmacologic properties, such as the antihistaminic and analgesic effects of some antidepressant agents are also reviewed.

Psychiatric and Psychological Co-Morbidity in Patients with Dermatologic Disorders

AbstractPsychiatric and psychological factors play an important role in at least 30% of dermatologic disorders. In many cases the impact of the skin disorder upon the quality of life is a stronger predictor of psychiatric morbidity than the clinical severity of the disorder as per physician ratings. Furthermore, in certain disorders such as acne and psoriasis, the psychiatric co-morbidity, which can be associated with psychiatric emergencies such as suicide, is an important measure of the overall disability experienced by the patient. The severity of depression and increased suicide risk are not always directly correlated with the clinical severity of the dermatologic disorder. Consideration of psychiatric and psychosocial factors is important both for the management, and for some aspects of secondary and tertiary prevention of a wide range of dermatologic disorders. It is useful to use a biopsychosocial model which takes into account the psychological (e.g. psychiatric comorbidity such as major depression and the impact of the skin disorder on the psychological aspects of quality of life) and social (e.g. impact upon social and occupational functioning) factors, in addition to the primary dermatologic factors, in the management of the patient. Some dermatology patients are likely to benefit from psychotherapeutic interventions and psychotropic agents for the management of the psychosocial comorbidity, in addition to the standard dermatologic therapies for their skin disorder.

A psychocutaneous profile of psoriasis patients who are stress reactors: a study of 127 patients

Psoriasis is a chronic, relapsing, cutaneous condition with a 1%-2% prevalence in the general population. About 40% of psoriatics report that psychosocial stress significantly exacerbates their condition. However, the clinical characteristics of the subgroup of psoriatic patients who are stress reactors have not been delineated. At a practical clinical level it is therefore difficult to implement specific psychosocial treatments among the psoriatic population. In this study, we compared the psychocutaneous characteristics of patients who reported that stress exacerbated their psoriasis, i.e., the high stress reactors (N = 64) to the subgroup who reported no significant association between stress and their psoriasis, i.e., the low stress reactors (N = 63). The high stress reactors had more disfiguring disease clinically (p less than 0.02); psychologically they tended to rely more upon the approval of others (p less than 0.05) and experienced more psoriasis-related daily stress (p less than 0.005). The high stress reactors also reported more flare-ups of their psoriasis during the 6 months prior to admission (p less than 0.05). We have shown that the high stress reactors can be clinically delineated from the low stress reactors. Certain psychosocial interventions will most likely decrease the morbidity associated with psoriasis among the high stress reactors, and may possibly even result in a decline in the number of major flare-ups of the psoriasis.

Psoriasis and sex: a study of moderately to severely affected patients

Background Psoriasis can have a significant impact upon sexual functioning for 30%—70% of patients. We examined the dermatologic and psychologic factors associated with the effect of psoriasis on this important dimension of qualify of life.
