Patients carrying the T allele of D1-rs11206244 showed a significant response to 8 week of antidepressant treatment in comparison with non-carriers of the allele buy 20mg cialis professional free shipping. Additionally order cialis professional 40 mg with mastercard, there was no effect of T allele on sertraline response order cialis professional 20mg free shipping, suggesting that the polymorphism is not associated to antidepressant effect (Cooper-Kazaz et al. As we mentioned, the T allele of D1-rs11206244 showed lower T3 and higher rT3 than non-T carriers (de Jong et al. Thus, it seems that patients genetically characterized by poor conversion of T4 to T3, are better responders to T3-antidepressant co-treatment (Cooper-Kazaz et al. Another study evaluated whether baseline thyroid function and D2 rs225014 (D2-Thr92Ala) predict response to paroxetine. However, up to date there is no study evaluating the influence of T3 and D2 polymorphisms on antidepressant response. Based on these observations, we evaluated the presence of D2 polymorphism related with a lower activity of the enzyme: D2-Thr92Ala (T/C). We concluded that Thr92Ala polymorphism of D2 gene could be considered a predictive marker of clinical response to fluoxetine, and hence of pharmacological therapy, but more studies are needed to confirm this preliminary results. The presence of these polymorphisms could influence basal activity of type 2 deiodinase, and therefore of T3 bioavailability in the brain. Use of thyroid hormone in depression Several studies using thyroid hormones in the management of patients with mood disorders have been reported since the early seventies. In patients receiving electroconvulsive therapy, those treated with T3 required less sessions and presented less memory loss compared with placebo treated group (Stern et al. T3 has been employed in initial combination therapy, and T3 or T4 in refractary depression or non responder patients. T3 in doses of 20 to 50 g is able to enhance the effect of tricyclic antidepressants and shorten the depression period but, many studies have not demonstrated differences in the number of patients recovered (Prange et al. A meta-analysis showed that when T3 was used in refractary depression in addition to tricyclic antidepressant therapy, patients treated with it were twice as likely to respond as controls, decreasing depression severity scores (Aronson et al. All those cases were treated mainly with fluoxetine in a daily dose of 20 to 40 mg/ and 25-50 g of T3, with few side effects. Some authors have suggested that T4 augmentation is less effective than T3 (Joffe&Singer, 1990) and that supra physiological doses (250-600 ug/day) are needed, as has been demonstrated in patients with resistant major depression or refractary uni and bipolar disorders (Baumgartner et al. These results support the theory of a reduced deiodination of T4 compatible with an inhibition of the D2 or a stimulation of the D3 in brain tissues resulting in reduced local T3 concentration. Main limitations of the studies are: small number of cases, lack of a placebo group, heterogeneity in diagnosis criteria, differences in observational period and in antidepressant therapy. We studied the effect of adding T3 in a dose of 50 ug per day (n=11) or placebo (n=10), to the standard antidepressant therapy with fluoxetine during 8 weeks. The difference between initial and 2 month was highly significant in both groups (using paired t tests). Although, we could not demonstrated in this particular group, a significant antidepressant effect. They have been employed to image and quantify brain perfusion, flow and metabolism in several conditions as well as the radionuclide techniques have been used to map neurotransmissors, receptors, drug actions and many metabolic pathways. Functional imaging in mood disorders may show abnormalities at different brain levels that could normalize with therapy. Several serotonin and adrenergic markers have also been employed to study negative emotional stimuli response in mood disorders. For instance: thalamic activity was increased by reboxetine, whereas citalopram primarily affected ventrolateral prefrontal regions. It would be interesting to have a method able to predict therapy responses to either noradrenergic or serotoninergic antidepressants (Carey et al. It is also known that even mild hypothyroidism may produce changes in brain regions modulating attention, motor speed, memory and visual-spatial processing. Hypothyroidal patients were also significantly more depressed, anxious and psychomotor slowered than euthyroidal subjects (Nagamachi et al. Brain metabolism and flow are usually decreased in major depression and bipolar disease being metabolism inversely associated with the severity of depression. Changes are variable and as we mentioned earlier, could reverse with adequate therapy. Subgenual prefrontal cortex presents abnormal blood flow and metabolism in the depressed state. Prefrontal cortex and limbic structures are involved in emotion regulation and amygdale is involved in emotional memory formation (Buchsbaum et al. Morphometric studies have evaluated hippocampus volume association with response to treatment. Patients who remit have larger pretreatment hippocampus volumes bilaterally compared with those who do not remit. A recent work demonstrated a significantly thinner posterior cingulate cortex in non-remitters than in remitters, and also significant decrease in perfusion in frontal lobes and anterior cingulate cortex in non-remitters compared with healthy controls, at baseline (MacQueen, 2009; Jrnum et al. Changes in amygdala activation when processing negative faces expressions might serve as an indicator for improved frontolimbic control required for clinical response (Ruh, 2011).

Hypotheses and explorative questions Based on the studies of these issues generic 20 mg cialis professional visa, we define the hypotheses as follows: H1: We suppose the patient with thyreopathy will be less resilient (they will be with less sense of coherence and with a tendency to external locus of control) that the control group buy cialis professional 40mg low cost. It is described in the literature that people with a high level of resilience are Psychosocial Factors in Patients with Thyroid Disease 291 physically healthier and there is a higher probability with them to stay healthy (e cialis professional 40mg line. Moreover, a difficult life situation can result in lowering the feeling of control over the life (comp. H2: We suppose the ills with thyreopathy will use rather non-effective coping strategies compared to the control group. Ma, Luo and Zeng (2002) have realised in ill people non-effective coping strategies, compared to the healthy ones. H3: We suppose the patients with thyreopathy will show lower quality of life, less life satisfaction than the control group. H4: We suppose the patients with thyreopathy will experience more negative emotions (depression and anxiety) that the control group. It is known that especially anxiety and depression occur in patients with different diagnoses (e. H5: We suppose the patients with thyreopathy will perceive higher social support compared to the healhy ones. With regard to the fact it is dealt with a planned operation mobilisation of patient social network and providing increased social support can be presupposed, and even from the side of medical staff. Differences between the ills and healthy ones have not been proved (Winsa et al, 1991; Yoshiuschi et al. Kukleta, 2001) research was an exception, were less support was shown in patients probably due to the reason the disease is developed with insufficient social support in an easier way. H6: We suppose that increase of resilience occurs in time within a half-year follow up in patients (growth of the sense for coherence and tendency to internal locus of control). The researches show that even if the sense for coherence can show itself as a stable trait, difficult life situations can change mans view of the world (Schnyder, 2000). After experiencing surgery (situation with less control) patients can gradually perceived a growth of the control over their lives (comp. H7: We suppose that the patients with thyreopathy will begin to choose effective coping strategies in time within a half-year follow up. Even earlier experience plays a specific role in managing and choice of coping strategy (comp. The patients could acquire more adaptive strategies of manageability with the help of coping with surgery and they could be stimulated to this by the contacts with doctors, and so on. Satisfaction and quality of life usually increases with decrease of health problems that we suppose after an operation (comp. H9: We suppose that decrease of negative emotions (depression and anxiety) occur in patients with thyreopathy within a half-year follow up. There should be less negative emotions with presupposed improvement of the health status due to the surgery (comp. H10: We suppose that decrease of perceived social support occur in patients with thyreopathy within a half-year follow up. After initial mobilisation of the social support (including medical staff) due to the surgery, there will be its decrease, when the surroundings begin to consider the patient as healthy, cured. With respect to these unexplored issues we have also been interested in answers to the following explorative questions: Q1: What are the differences in the observed variables among the patients with different thyreopathies? We regard comparison of such type a very interesting and we have not been informed on any similar researches. Q2: What is the composition of the key areas (life topics) in the framework of quality of life, what importance and satisfaction with individual areas patients with thyreopathy will mention within the follow up period and how it is going to be in the control group? It is necessary to await that disease, treatment effects the quality of life not only in its total height, but also concerning the composition and importance of individual areas (cues) and their satisfaction with them (Kivohlav, 2002). Connection of the quality of life with resilience and social support is described in the literature, on the contrary, stress and negative emotions should deteriorate it. A statistically significant difference between the patients and the control group has not been proved in average scores of the total sense of coherence. An significant difference of average scores have not been proved in scores between the patients and the control group, neither in comprehensibility, nor in manageability, or in meaningfulness. Statistically significant difference has not been proved in average scores of completely perceived social support between the experimental and control groups. Statistically significant difference has not been proved between the two groups in the social support from an important, not closely specified person, neither concerning the social support from friends. Statistically significant difference of averages has not been found out in patients and healthy persons in any of the coping strategies. An exception is a strategy of planning where it has been showed on the edge of statistical significance, respectively closely behind it, that it is used more frequently by the healthy respondents than the ills with thyreopathy. On the edge of statistical significance, respectively closely behind it, it is indicated that higher life satisfaction has been mentioned by the member of the control group that the patients. Statistically significant difference in average scores of depression has not been proved between the patients and the control group. Higher variance in locus of control on the edge of statistical significance has been found out in the patients compared with controls.
