TRANSPLANTATION PSYCHIATRY: AN OVERVIEW

Psychiatric consultation and evaluation is an important part of candidate selection for organ transplantation. Psychiatric assessment of patients undergoing transplantation procedure is done in pre- and post transplantation periods, each one having its specifics. In the pre-transplantation period it is crucial to assess the patient’s therapeutic adherence and the ability of understanding the treatment. The main prediction factor for short and long-term success is medical compliance for which thorough clarification of psychosocial support is needed. Symptoms of psychological exhaustion due to physical illness should be distinguished from psychiatric disorders. If a patient has a history of psychiatric illness, the risks of exacerbation or recurrence of a disease need to be evaluated. Pharmacokinetic and pharmacodynamics of psychotropic drugs resulting from to organ failure should be considered when deciding on treatment. Psychiatric assessment of the organ donor aims to clarify the psychological suitability and motivation. There are specific aspects of liver, kidney, heart and lung transplantation to keep in mind. Understanding psychosexual development is particularly important to children, before transplantation, as is the assessment of every family member. The consultation concludes with an overall evaluation of the patient\u27s psychosocial strengths and limitations and recommended interventions to optimize the candidacy for transplantation. In the post-transplantation period potential psychological problems or psychiatric disorders must be identified and treated accordingly, in addition to psychiatric side effects of immunosuppressive therapy. The use of psychotropic drugs in the post-transplantation period requires knowledge of medication interactions. Overall, psychiatrists perform multiple roles in the transplantation team. The psychiatrists’ goals are to meet the psychological needs of both patients and potential donors, evaluate candidates and to help other medical experts on the team with understanding underlying psychological mechanisms triggered by serious medical conditions and procedures. Finally, the most important purpose is optimal organ recruitment and recovery

The influence of 5-HT(2C) and MDR1 genetic polymorphisms on antipsychotic-induced weight gain in female schizophrenic patients

We investigated the relationships between functional genetic variants of the 5-HT(2C) receptor and multidrug-resistant protein (MDR1), coding for P-glycoprotein, and second generation antipsychotic (SDA)-induced weight gain among 108 female schizophrenic patients treated with olanzapine or risperidone for up to 4 months. No significant differences in -759C/T allelic and genotype variants of 5-HT(2C) were found between patients who gained more than 7% of their initial weight compared with those who gained less. Haplotype-based analysis of two MDR1 loci, exon 21 G2677T and exon 26 C3435T, revealed a slightly lower representation of the G2677/C3435 haplotype in the >/=7% group. In the subgroup of patients treated with risperidone, we found borderline overrepresentation of 2677T, significant overrepresentation of 3435T variant and borderline overrepresentation of 2677T/3435T haplotype the >/=7% group, whereas G2677/C3435 haplotype was found to be less represented in the >/=7% group. Our data indicate a nonsignificant role of 759C/T 5-HT(2C) in SDA-induced weight gain, and a stronger influence of the MDR1 G2677T and C3435T polymorphisms on risperidone-induced weight gain in female schizophrenic patients. 3435T and 2677T MDR1 variants, both associated with lower P-gp function, might predispose to higher risperidone accessibility to the brain that would lead to stronger effects, including weight gain

THE COMORBIDITY OF DIABETES MELLITUS AND PSYCHIATRIC DISORDERS

Diabetes mellitus is a chronic disease affecting approximately 6% of the general population. Depression and schizophrenia are often comorbid with diabetes. There are two main ways to explain this phenomenon. Firstly, patients with diabetes mellitus have higher incidence of psychiatric disorders and secondly, antidepressants and antipsychotics may cause metabolic abnormalities. Antidepressants with noradrenergic activity have the highest potential to cause metabolic abnormalities. In schizophrenia, the risk is highest with clozapine and olanzapine pose the highest risk, moderate for risperidone and quetiapine, while ziprasidone and sertindole have not been associated with diabetes. American Diabetes Association and American Psychiatric Association suggested that optimal management of patients with schizophrenia should include baseline assessment on their weight, waist circumference, blood pressure, blood glucose level and lipidogram and family history on obesity, diabetes, dyslipidemia, hypertension and cardiovascular illness. During the first three months, weight gain should be monitored on monthly basis, while biochemical analysis should be performed after the first three months, and then once a year. In patients with significant weight gain, increase of blood glucose level or dyslipidemia, the first intervention should be switch to another antipsychotic. If necessary, a patient should be referred to an endocrinologist and advised on changing their life style

Takotsubo cardiomyopathy after the first electroconvulsive therapy regardless of adjuvant beta-blocker use: a case report and literature review

Takotsubo cardiomyopathy (TC) is a rare complication of electroconvulsive therapy (ECT), an effective and safe treatment for severe cases of depression and psychosis. There are reports on 16 patients who developed TC after ECT, and these were predominantly female patients treated with antidepressants for depressive disorder. We describe a case of a 40-year-old male patient, with a history of schizophrenia and heavy caffeine and nicotine use, treated for acute psychotic episode with haloperidol and clozapine. Propranolol was administered because of clozapine-induced tachycardia. After 8 weeks without therapeutic response, the patient was referred for standard ECT procedure, which included premedication and bifrontotemporal stimulation. Two hours later, the patient experienced gastric pain and had increased troponin and natriuretic peptide levels and ST-elevation. After inotrope and anticoagulant treatment and replacement of antipsychotics, the patient remained stable. Contrary to common opinion, previous adrenergic blockade in this patient did not prevent TC occurrence. TC pathophysiology remains unclear although it has been related to the burst of norepinephrine neurons. Psychosis has also been associated with catecholamine dysfunction, and excessive psychological stress with long-term norepinephrine dysfunction. Animal models have shown that ECT, clozapine, and nicotine and caffeine use could considerably increase catecholamine levels. Clinical understanding of rare cardiac ECT complications could improve early recognition of patients at risk for TC and ensure safe ECT protocols

Instrumented joint mobility analysis in traumatic transtibial amputee patients

Aim: The presented study reports a quantitative gait analysis and different adaptive strategies evaluation on 12 male adults, war trauma transtibial (TT) amputees, fitted with prostheses. Methods: Gait analysis included kinematics (joint mobility variables) prosthetic and healthy legs in 12 TT amputees and 12 able-bodied persons/individuals. Results: The results disclose asymmetry in gait parameters between the amputated and sound legs, as well as between transtibial amputees and able-bodied persons.Kinematic results of the amputees and a control group, showed significantly reduced prosthetic maximum ankle plantar flexion (p<0.01), decreased hip adduction (p< 0.05) and increased knee flexion at stance phase (p< 0.1) for the left, healthy legs of amputees. Conclusion: Although adult traumatic TT amputees have great potential for enhancement of function through appropriate rehabilitation and use of effective prosthetic devices, they adapt a unique way of ambulating with the prosthesis. An instrumented gait analysis study is able to provide assessment of the way prosthetic transtibial amputees walk, as objective information to supplement clinical observation

Posttraumatic Stress Disorder in Women – Experiences form the Psychiatric Clinic, University Hospital Center Zagreb, Croatia

Posttraumatic stress disorder (PTSD) is an anxiety disorder that develops after a severe traumatic event or experience. Lifetime prevalence rate in the European population is 1.9 % and it is higher for women (2.9%) then for men (0.9 %). The aim of this study was to examine rates and sociodemographic and clinical characteristics of women with PTSD who were hospitalized at the Psychiatric clinic of University Hospital Center in Croatia over the years 1990–2007. Data were gathered retrospectively from the medical charts. We found that 67 women were diagnosed with PTSD which is 0.58% of all admissions over these years. Majority suffered from comorbid depression (N=51) and various somatic conditions, especially malignant gynecological tumors (N=23). No significant differences were found in distribution of PTSD symptoms in relation to the combat vs. civilian trauma. We found that patients with combat trauma often suffer from comorbid depression, while those with civilian traumas more often reported somatic conditions, especially malignant gynecological tumors. Our institution is a speciality clinic at a tertiary care medical center which tends to accumulate patients with serious forms of the disorder, and therefore our results can not be generalized to other settings involved in working with women with PTSD. Our results indicate that psychiatrists’ assessment of female patients should inevitably include lifetime traumatic experiences, and among those with PTSD, special attention should be paid to comorbid depression and malignant tumors

Impact of War Trauma and Posttraumatic Stress Disorder on Psychopathology in Croatian and German Patients with Severe Mental Illness

Aim To explore posttraumatic stress symptoms and current psychopathology in a binational sample of Croatian and German participants with severe mental illness. Methods We studied 178 inpatients from the Greifswald University (German patients, n = 89) and University Hospital Zagreb and Ivan Barbot Neuropsychiatric Hospital (Croatian patients, n = 89) with either major depression (n = 150), schizophrenia (n = 26), or bipolar disorder (n = 2). Measurements included Posttraumatic Diagnostic Scale and the Symptom Check List-90-R. Participants were matched according to age, sex, and diagnosis. Results Croatians reported significantly more war traumatic events (64/82 vs 5/74, χ2 1 = 77.142, P < 0.001) and significantly more Croatians met the criteria for posttraumatic stress disorder (55/89 vs 27/89, χ2 1 = 17.73, P < 0.001). They also suffered from a higher level of psychopathological distress as they scored significantly higher at all Symptom Check List-90-R revised version subscales (P < 0.001). The regression models demonstrated that predictors of general psychopathological distress were war trauma (P < 0.001), posttraumatic stress disorder (P < 0.001), and diagnosis (P = 0.01). Conclusion This is the first study comparing the impact of war trauma on psychopathology of participants with severe mental illness between two nations. Our results clearly indicate the importance of trauma assessment in subjects with severe mental illness, particularly in postconflict setting
