[Interferon α therapy in patients with chronic hepatitis C infection: biopsychosocial consequences]. / Interferon α bei Patienten mit chronischer Hepatitis C : Biopsychosoziale Auswirkungen.

BACKGROUND: Interferon α (IFN-alpha) is widely used in the treatment of viral infections, including hepatitis C. Unfortunately depression is a common side effect of IFN-alpha therapy. The presence of depressive symptoms is important because they have an adverse effect on the course of the illness and reduce the quality of life and the treatment adherence. The current prospective study examines the effects of IFN-alpha on the development of depressive disorders, on cognitive functioning and on quality of life. METHOD: A total of 25 patients with chronic hepatitis C infection were investigated. All patients were treated in the Department of Gastroenterology and Hepatology, University of Medicine of Graz, Austria. Psychometric observer rating and self-rating scales were administered 1 month and 3 months after the beginning of the antiviral treatment to evaluate depressive symptoms [Beck Depression Inventory (BDI); Hamilton Depression Scale]. The data on life satisfaction before therapy and health-related quality of life were obtained from the Fragebogen zur Lebenszufriedenheit (FLZ) and the SF-36 (Health Status Questionnaire). Cognitive function was based on the SKT (Syndrom Kurztest). All patients completed the Social Support Questionnaire (SSS), a multidimensional self-report measure of social support. RESULTS: Three months after the initial IFN-alpha administration in the whole sample significant impairments in health-related quality of life were found in the health-related domains "physical functioning", "role physical", "role emotional", "social functioning" and "vitality". The whole sample showed cognitive impairments. No changes in social support were recorded. Three months after the first INF-alpha administration, 48% (n=12) of the sample suffered from moderate clinical depression. In comparison to patients without pathological affective findings, patients with INF-alpha-induced clinical depression showed decreased life satisfaction before the initial antiviral therapy. Impairments in health-related quality of life (SF-36) were found in the sample with clinical depression in the health-related domains "general health", "social functioning", "role emotional", "vitality" and "mental health". CONCLUSION: Hepatitis C is associated with an increased prevalence of psychiatric disorders, particularly depression. INF-alpha patients having low levels of life satisfaction in the domains "self-concept" (skills, appearance, self-confidence, vitality …), "employment" and "physical health and constitution" seem to face a major risk of depression.

[Emotional status, cognitive performance and quality of life in HIV-infected patients. Results of an exploratory study]. / Emotionale Befindlichkeit, kognitive Leistungsfähigkeit und Lebensqualität bei HIV-Patienten. Ergebnisse einer explorativen Untersuchung.

BACKGROUND: Due to the change of HIV disease from an acute life-threatening disease to a chronic infection, it is more psychosocial rather than therapeutic aspects that have become of interest in scientific investigations. The purpose of this exploratory study was to evaluate emotional distress, health-related quality of life (HRQoL) and cognitive performance. The diagnosis of HIV was considered a life event that may lead to post-traumatic stress syndrome. METHOD: We recruited 37 HIV-positive outpatients and assessed the frequency of depressive (BDI) and post-traumatic stress symptoms (PTSS) due to the diagnosis of HIV (IES), HRQoL (SF-36) and cognitive performance (SKT). Further, the new diagnostic concept of adjustment disorder as a stress response syndrome according to Maercker was considered. RESULTS: Of the 37 Patients, 67.6% (n=25) of the sample had a post-traumatic stress syndrome. The HIV-related PTSS was considered adjustment disorder using the concept proposed by Maercker. Fourteen patients (37.8%) suffered from a depressive syndrome, and 27% (n=10) showed cognitive deficits (minimal: n=8; mild: n=1; moderate: n =1). HIV-positive patients with PTSS had significantly unfavourable values in the SF-36 domains general health (p=0.003), vitality (p=0.007), social functioning (p=0.000), role-emotional (p=0.016) and mental health (p=0.000). CONCLUSION: HIV-infected patients may face a major risk of HIV-related PTSS in the sense of adjustment disorder according to Maercker, depression and cognitive dysfunction. The presence of emotional distress is associated with impairments in quality of life. We therefore suggest an early and comprehensive bio-psycho-social assessment and therapy of HIV-infected patients.

[The effects of coronary artery bypass graft surgery on health-related quality of life, cognitive performance, and emotional status outcomes: a prospective 6-month follow-up consultation-liaison psychiatry study]. / Prospektive Untersuchung zu den Auswirkungen aortokoronarer Bypassoperationen auf die gesundheitsbezogene Lebensqualität, kognitive Performanz und emotionale Befindlichkeit im 6-Monats-Verlauf. Ergebnisse einer konsiliarpsychiatrischen Follow-up-Studie

The success of routine coronary artery bypass graft surgery (CABG) is now no longer judged solely by its effects on traditional end points such as mortality rates but by its influence on biopsychosocial dimensions. The aim of this study was to assess the course of health-related quality of life, cognitive and emotional change during the six months after elective CABG, and to investigate how cognitive impairments, depression and posttraumatic stress symptoms were related to quality of life. In a prospective study, we followed up for 6 months 138 of the original 147 patients who had undergone elective CABG surgery. Preoperatively, and at 6 months after surgery, a series of psychometric observer-rating and self-rating scales were administered to evaluate cognitive functioning (SKT), depressive symptoms (BDI), posttraumatic stress symptoms (PTSS-10), and health-related quality of life (SF-36 Health Status Questionnaire). The measurements of health-related quality of life (HRQOL) indicated significantly higher SF-36 values on all of the eight health-related domains from preoperative to 6-month follow-up assessments. However, at 6-month follow-up, patients with clinical depression had significantly lower SF-36 values on all of the eight health-related domains when compared with patients without depression. Also, at 6-month follow-up, patients with posttraumatic stress disorder (PTSD) had significantly lower SF-36 values on six of the eight SF-36 health categories when compared with patients without PTSD. Finally, at 6-month follow-up, patients with cognitive deficits had significantly lower SF-36 values on physical functioning when compared with patients without cognitive impairments. We underscore the need for early and comprehensive bio-psycho-social diagnosis and therapy of post-CABG patients in order to treat emotional distress and CABG-related cognitive impairments and enhance patients' quality of life at an early stage after cardiac surgery.

[Sexual dysfunction in remittent depressive women]. / Sexualleben remittierter depressiver Patientinnen.

BACKGROUND: Very little is known about the incidence of sexual problems in remittent depressive women, which are independent of prescribed medication. The current study examined the sexual life of such remittent patients and the effects of sexual dysfunction on the quality of life. METHOD: A total of 39 female patients who had no sexual side effects caused by antidepressive medication and 39 healthy subjects were investigated. All patients were treated in the Department of Psychiatry, University of Medicine of Graz, Austria. The data on sexual problems and quality of life were obtained from the short questionnaire for sexual problems (KFSP-F) and the questionnaire on quality of life (FLZ). RESULTS: Even after remission, reduced libido and impaired sexual fantasies appeared to be the core sexual problems. Remittent depressive women with sexual dysfunction had a decreased quality of life. CONCLUSION: Impaired sexual function is a common feature in depressive disorders. In some cases sexual problems even persist after remission and the observed sexual dysfunctions negatively affect quality of life. A detailed patient history is important to detect sexual problems.

[The effects of stalking on psychiatrists, psychotherapists and psychologists. Prevalence of stalking and its emotional impact]. / Auswirkung von Stalking auf Psychiater, Psychotherapeuten und Psychologen. Häufigkeit von Stalking und dessen emotionale Folgen.

Stalking in the psychiatric context describes a pathological behaviour which is characterized by repeated persecution, harassment, or menacing of or assault on a person. Because of the association between stalking and mental disorders, psychiatrists, psychologists and psychotherapists belong to particularly exposed professions. If they fall victim to stalking during their career, disruptive impacts up to posttraumatic stress disorder (PTSD) can be the consequence. A total of 117 psychiatrists, psychologists or psychotherapists in Graz participated in an anonymous interview. To register possible experiences with stalking defined behaviour, a modified version of the questionnaire of Kamleiter was used. The prevalence and severity of posttraumatic stress symptoms were determined using the Impact of Event Scale of Horowitz. The study showed an incidence of stalking of 38.5%. The rate of female stalkers (60%) was extraordinary high. Most victims (68.9%) experienced non-violent threats. Most of the offenders (41.9%) were diagnosed as suffering from schizophrenia, schizotype and delusional disorders (F2) followed by disorders of adult personality and behaviour (F6) (30.2%). Some 44.4% of the victims developed symptoms of PTSD, which were usually only slight. The analyses suggest that stalking, in the psychiatric field of activity, is a common and serious phenomenon, and that strategies for the prevention and protection of potentially affected professions have to be developed.

[Clinical features, diagnosis, and treatment of dysphoric states and psychoses associated with epilepsy]. / Klinik, Diagnostik und Therapie epilepsieassoziierter depressiver Verstimmungen und Psychosen.

Although dysphoric states and psychoses represent clinically relevant psychiatric complications in patients with epilepsy, their symptomatologies are complex and therefore frequently underrecognized and undertreated in daily psychiatric routine. Detecting dysphoric states and psychoses secondary to the psychotropic effects of various antiepileptic drugs is often challenging, even for the most experienced psychiatrists. This article gives an overview of epidemiology, clinical features, diagnosis, and therapy of interictal, peri-ictal, and alternative dysphoric states and psychoses in patients with epilepsy. Further, potential drug interactions between antiepileptic and psychiatric medications are discussed.

[PTSD in somatic disease]. / Posttraumatische Belastungsstörungen bei somatischen Erkrankungen.

This review describes the incidence of posttraumatic stress disorder (PTSD) in physically ill patients. At the beginning, research in the field of PTSD was primarily focused on war veterans and victims of bodily assault or rape. Starting in the early 90 s, PTSD after civilian traumas such as motor vehicle accidents was diagnosed increasingly more often. Recent publications showed that PTSD can also follow serious somatic diseases. Hence, awareness during anaesthesia, prolonged ICU treatment (ARDS, septic shock), burns, successful resuscitation after cardiac arrest, coronary artery bypass surgery, organ transplantation and cancer were all linked to the development of PTSD. Prevalence of PTSD in these medical conditions lies around 5 - 10 %, and it is therefore considered an important comorbidity. Unfortunately, the diagnosis and treatment of PTSD are not well enough established yet and thus do receive too little attention in the treatment regime of somatic illness. Generally, PTSD can occur with every life-threatening disease, but possibly also with less severe diseases if the patient experiences intense fear. PTSD symptoms, especially intrusive recollections, avoidance and hyper-arousal can impair the patients' quality of life more than the primary disease. This seems to be also true for sub-syndromal PTSD. To adequately diagnose and treat patients at risk of developing PTSD, close collaboration between physicians of all subspecialties and psychiatrists will be necessary.

[Chronic fatigue syndrome]. / Schlafstörungen, Hypochondrie oder Suche nach dem Sinn des Lebens? Sechs Monate lang todmüde-- ohne organischen Befund.

The symptoms of fatigue and exhaustion, which are central to chronic fatigue syndrome and neurasthenia, can lay claim to being"psychopathological entities" in their own right. Although ubiquitous, they by no means reflect a homogeneous clinical picture. Chronic fatigue may occur after physical illness, such as viral infections, or be associated with a range of different psychiatric disorders. There is wide overlap with affective, anxiety, somatoform, and personality disorders, and this should be borne in mind when it comes to classifying these symptoms. To investigate the etiopathogenesis, multifactorial models are required. For treatment, adapted cognitive-behavioral therapy, possibly accompanied by an antidepressant, is effective.

[Depression in the medically ill: diagnosis and treatment considerations in C-L psychiatry settings]. / Depression bei körperlichen Erkrankungen--Diagnose und Therapie vor konsiliar-psychiatrischem Hintergrund.

Depression in general hospital patients is one of the main psychiatric problems in the medically ill. It often complicates the treatment and prognosis of patients with active medical conditions. However, depression in the medically ill is frequently under-recognized and under-treated. This article reviews the historical concept of secondary depression, and gives an overview of medical conditions and medications associated with depression. Phenomenological issues in the diagnosis of depression in medically ill populations and treatment considerations in C-L psychiatry settings will be discussed. The authors have used the examples of Parkinson's disease and epilepsy commonly associated with depression to illustrate how these considerations affect the C-L psychiatrist's choice of an antidepressant in the medically ill.

[Acute liver failure in nefazodone therapy? A case report]. / Akutes Leberversagen unter Nefazodon-Therapie? Ein Fallbericht.

Antidepressant-induced hepatotoxicity is generally considered of minimal clinical importance and is not well recognized. We report on a patient with recurrent major depression who was treated with nefazodone. Six weeks after initiation of therapy with nefazodone, he developed fatal liver failure. After cessation of the drug, the patient did not recover. He underwent liver transplantation but unfortunately died.

The effect of stress doses of hydrocortisone during septic shock on posttraumatic stress disorder in survivors.

BACKGROUND: Exposure to intense physical and psychological stress during septic shock can result in posttraumatic stress disorder in survivors. Patients with chronic posttraumatic stress disorder often show sustained reductions in serum cortisol concentration. This investigation examines whether increasing serum cortisol levels with hydrocortisone treatment during septic shock reduces the incidence of posttraumatic stress disorder in survivors. METHODS: Patients (n = 20) were recruited from a prospective, randomized double-blind study on the hemodynamic effects of hydrocortisone during septic shock. Eleven patients had received placebo and nine stress doses of hydrocortisone. Posttraumatic stress disorder was diagnosed 31 months (median) after intensive care unit discharge using SCID-IV (DSM-IV-criteria). Furthermore, the number of categories of traumatic memory from ICU treatment was determined in both groups at that time. RESULTS: Only one of nine patients from the hydrocortisone group developed posttraumatic stress disorder, compared with seven of 11 patients in the placebo group (p =.02). There was no significant difference with regard to the number of categories of traumatic memory between the hydrocortisone and placebo groups. CONCLUSIONS: The administration of hydrocortisone during septic shock in a dosage similar to the endogenous maximal production rate was associated with a lower incidence of posttraumatic stress disorder in long-term survivors, which seems to be independent of the number of categories of traumatic memory.

Changes in patterns of psychiatric referral in a German general hospital: results of a comparison of two 1-year surveys 8 years apart.

The aim of this study was to investigate the issues of changes in patterns of referral and interventions and of consistency of psychiatric diagnoses assigned by a psychiatric consultation-liaison service in a general hospital over an 8-year period. We compared two 1-year surveys 8 years apart. Survey A comprised 713 referrals in 1990, and Survey B included 1025 consecutive new consultations in 1998. Data pertained to demographic characteristics, source of referral, reason for referral, psychiatric diagnosis according to DSM-III-R, and intervention. Our study demonstrated significant changes in diagnostic characteristics and in patterns of referral and intervention over the years. Changes in source of referral and psychiatric diagnoses were associated with the increasing involvement of clinical psychologists and specialists in psychosomatic medicine. Also, surgeons and physicians were increasingly aware of psychiatric morbidity in medical-surgical populations. Modern psychopharmacological treatment approaches resulted in a higher rate of recommendation of psychotropic medication. To ameliorate the provision of psychiatric care for general hospital patients, the need for a biopsychosocial conceptual framework at the interface of psychiatry and medicine in general hospitals should be underscored.

The relationship between cognitive performance and employment and health status in long-term survivors of the acute respiratory distress syndrome: results of an exploratory study.

Survivors of acute respiratory distress syndrome (ARDS) are at risk for long-lasting cognitive decline due to hypoxemia, sepsis and/or psychological sequelae associated with aggressive supportive care in the intensive care unit (ICU). We conducted an exploratory study to assess cognitive performance in long-term survivors of ARDS and to investigate how cognitive functioning is related to employment status and health-related quality of life (HRQOL). At median time of 6.0 years after ICU discharge, forty-six ARDS survivors were tested with SKT, a short cognitive performance test for assessing deficits of memory and attention. A measure of HRQOL (SF-36 Health Status Questionnaire) was also administered, and in a brief psychiatric interview, employment status was rated. 23.9% (n=11) of the patients showed cognitive impairments. However, no extreme and severe cognitive deficits were recorded. They primarily revealed low levels of cognitive function in various tasks assessing attention skills. Disability was found in 41.3% (n=19) of the patients. All ARDS survivors with cognitive deficits were disabled, whereas only 22.9% (n=8) of the cognitively not impaired patients gave evidence of disability. The SF-36 values of the ARDS survivors indicated impaired health status on seven out of eight domains when compared to normative population data. Patients with cognitive deficits described the lowest HRQOL with major limitations in the domains role-physical and social functioning when compared to patients without cognitive impairments. In conclusion, long-term ARDS survivors exhibit impaired health status and the presence of cognitive deficits is associated with disability and considerable impairments in HRQOL. More detailed psychiatric research is required to establish the etiology of these cognitive impairments.

Pulmonary function and health-related quality of life in a sample of long-term survivors of the acute respiratory distress syndrome.

OBJECTIVE: We performed a follow-up cohort analysis in order to delineate the correlation between pulmonary function (PF) and health-related quality of life (HRQL) in patients after ARDS. DESIGN: Follow-up cohort study. SETTING: A 20-bed ICU of a university teaching hospital. PATIENTS: A cohort of 50 long-term survivors of ARDS. MEASUREMENTS AND RESULTS: Measurements of PF (FVC, FEV1, TLC, D(LCO)) and HRQL (SF-36 Health Status Questionnaire) were made 5.5 years (median value) after discharge from the ICU. Impairments in PF (defined as PF results below 80% of the predicted value) were frequent but generally mild. Twenty patients had a single PF impairment (with limitations in FEV1/FVC ratio in 12 patients being the most common), four patients had two (with D(LCO) and FEV1/FVC ratio impairment the most common) and three patients had pathologic results in three PF tests (FEV1/FVC ratio, TLC and capillary pO2 during exercise in one case, FVC, TLC and capillary pO2 during exercise in the second patient and FVC, TLC and D(LCO) in the third). Compared to normal controls, survivors of ARDS showed impairments in all SF-36 health dimensions (p < 0.001). Patients with multiple (> 1) PF impairments described the lowest HRQL with major limitations in all SF-36 categories (p < 0.037) including physical and mental summary scores (36.5 vs 46.9, p = 0.037 and 31.3 vs 51.4, p = 0.003) when compared to patients with no or only one PF impairment. CONCLUSIONS: Long-term survivors of ARDS have a significant reduction in HRQL and the presence of multiple PF impairments is associated with maximal decrements in HRQL.

Treatment of depression with methylphenidate in patients difficult to wean from mechanical ventilation in the intensive care unit.

BACKGROUND: Mechanical ventilation is often required to support patients in the intensive care unit (ICU) with life-threatening cardiovascular, respiratory, or neuromuscular disorders. Occasionally, difficulties related to weaning patients from this support occur owing to depression. The traditional and newer-generation antidepressant drugs have a relatively long latency of response that interferes with rehabilitation attempts in the ICU. Psychostimulants such as methylphenidate show a rapid onset of antidepressant activity and a benign side effect profile. METHOD: As consulting psychiatrists in the consultation-liaison service of a university hospital, we treated 7 patients with complex ICU courses presenting prolonged mechanical ventilation and psychomotor retardation associated with markedly depressed mood (DSM-IV criteria) by giving them methylphenidate. Methylphenidate was started on the first day at a dose of 2.5 mg p.o. in the morning and was increased by 2.5 mg each day with twice-a-day dosing in the morning and at noon until the patient responded or showed side effects. A maximum dose of 15 mg/day was not exceeded. Outcome evaluation was performed using the Clinical Global Impressions scale. RESULTS: Five (71 %) of 7 patients showed marked or moderate improvement in mood and activity within 3 to 4 days, and discontinuation of ventilator support was achieved within 8 to 14 days. Side effects with these 5 patients were not encountered. Of the remaining 2 patients (29%), 1 developed psychomotor agitation and anxiety within 4 days. Another patient showed only minimal improvement with regard to activity. CONCLUSION: Methylphenidate might be a rapidly effective and safe treatment for depression in difficult-to-wean patients hospitalized for life-threatening medical illness in the ICU. Implications for future research for this population of patients warrant formal randomized, prospective, clinical case-control evaluation.

Health-related quality of life and post-traumatic stress disorder in patients after cardiac surgery and intensive care treatment.

OBJECTIVES: Health-related quality of life and patient satisfaction have become important end points in cardiac surgery. Post-traumatic stress disorder has been described in patients with life-threatening heart disease. In this study, we investigated the occurrence of post-traumatic stress disorder in a sample of patients after cardiac surgery and compared health-related quality of life and patient satisfaction between patients with and without evidence of post-traumatic stress disorder. METHODS: We studied 80 patients serially admitted to the intensive care unit after cardiac surgery (bypass grafting, n = 51; aortic valve replacement, n = 29). Health-related quality of life was assessed with the use of the SF-36 Health Status Questionnaire. Post-traumatic stress disorder was measured with a previously validated instrument (the Post-Traumatic Stress Syndrome 10-Questions Inventory), and 20 different aspects of life satisfaction were quantified on a scale ranging from 0 to 10. For measurements of health-related quality of life and post-traumatic stress disorder, age- and gender-comparable healthy individuals, as well as patients with cardiovascular diseases, served as control groups. RESULTS: Patients who had cardiac surgery described high life satisfaction summary scores (156 of a maximum of 200 points) and only small impairments in physical and mental SF-36 summary scores when compared with healthy control groups (median reduction 7.15, P <.05). Patients with evidence of post-traumatic stress disorder (n = 15) reported the lowest SF-36 mental health summary scores when compared with patients without stress disorder (38.3 vs 48.4, P =.004) and rated their life satisfaction lower (121.5 vs 162.0, P =.002). CONCLUSIONS: Patients who have had cardiac surgery demonstrate a high life satisfaction with an acceptable degree of physical and mental health-related quality of life. Impairments in psychosocial function and life satisfaction were found in a subgroup of patients with evidence of post-traumatic stress disorder.

Suicide attempt by pure citalopram overdose causing long-lasting severe sinus bradycardia, hypotension and syncopes: successful therapy with a temporary pacemaker.

In few cases, pure citalopram overdose at doses above 600 mg showed electro-cardiographic changes with prolonged QT intervals and sinus bradycardia gradually resolving within 12-24 hours after intoxication. We report on a 32-year-old patient with borderline personality disorder (BPD) who ingested a total of 800 mg citalopram to attempt suicide due to an interpersonal disappointment. She developed severe sinus bradycardia with a minimal pulse rate of 41/min within about 4 hours after intoxication lasting up to six days during intensive care unit (ICU) treatment. Further, hypotension and syncopes occurred. No QT interval prolongations were recorded. To our knowledge, this is the first case report of pure citalopram overdose-induced long-lasting sinus bradycardia associated with severe hypotension and intermittent syncopes that required therapy with a temporary pacemaker.

Sensitivity and specificity of a screening test to document traumatic experiences and to diagnose post-traumatic stress disorder in ARDS patients after intensive care treatment.

OBJECTIVE: Many survivors of critical illness and intensive care unit (ICU) treatment have traumatic memories such as nightmares, panic or pain which can be associated with the development of posttraumatic stress disorder (PTSD). In order to simplify the rapid and early detection of PTSD in such patients, we modified an existing questionnaire for diagnosis of PTSD and validated the instrument in a cohort of ARDS patients after long-term ICU therapy. DESIGN: Follow-up cohort study. SETTING: The 20-bed ICU of a university teaching hospital. PATIENTS: A cohort of 52 long-term survivors of the acute respiratory distress syndrome (ARDS). INTERVENTIONS AND MEASUREMENTS: The questionnaire was administered to the study cohort at two time points 2 years apart. At the second evaluation, the patients underwent a structured interview with two trained psychiatrists to diagnose PTSD according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria. The reliability and validity of the questionnaire was then estimated and its specificity, sensitivity and optimal decision threshold determined using receiver operating characteristic (ROC) curve analyses. RESULTS: The questionnaire showed a high internal consistency (Crohnbach's alpha = 0.93) and a high test-retest reliability (intraclass correlation coefficient alpha = 0.89). There was evidence of construct validity by a linear relationship between scores and the number of traumatic memories from the ICU the patients described (Spearman's rho = 0.48, p < 0.01). Criterion validity was demonstrated by ROC curve analyses resulting in a sensitivity of 77.0% and a specificity of 97.5% for the diagnosis of PTSD. CONCLUSIONS: The questionnaire was found to be a responsive, valid and reliable instrument to screen survivors of intensive care for PTSD.
