RESUMO

OBJECTIVE: Omega-3 (n-3) and omega-6 (n-6) polyunsaturated fatty acid (PUFA) alterations in patients with major depressive disorder (MDD) have been shown to persist after remission. Whether these alterations are risk factors for MDD recurrence remains unknown. Here, we examined whether fatty acids predict time until MDD recurrence in remitted MDD patients. METHODS: Data were used from remitted MDD patients of the Netherlands Study of Depression and Anxiety (n = 356) and the Depression Evaluation Longitudinal Therapy Assessment studies (n = 118). Associations of FAs with time until MDD recurrence up to 8-year follow-up were analyzed using Cox regression analyses. Study-specific estimates were pooled using mega- and meta-analysis techniques. RESULTS: 27.5% (NESDA) and 56.8% (DELTA) participants had an MDD recurrence. Pooled results showed that no FA was significantly associated with time until MDD recurrence (n-3 PUFAs: hazard ratio (HR) = 1.17, 95% confidence interval (CI) = 0.98-1.41, P = 0.082; n-6 PUFAs: HR = 1.08, 95% CI = 0.84-1.38, P = 0.55). CONCLUSION: In remitted MDD patients, circulating PUFAs were not associated with prospective risk of MDD recurrence. Consequently, circulating PUFAs are unlikely to reflect a vulnerability marker for recurrence, so correcting n-3 PUFA 'deficits' through supplementation does not seem a promising option to prevent MDD recurrence.

RESUMO

Continuous research into the pathophysiology of psychiatric disorders, such as major depressive disorder (MDD), posttraumatic stress disorder (PTSD), and schizophrenia, suggests an important role for metabolism. This narrative review will provide an up-to-date summary of how metabolism is thought to be involved in the pathophysiology of these psychiatric disorders. We will focus on (I) the important role of fatty acids in these metabolic alterations, (II) whether fatty acid alterations represent epiphenomena or risk factors, and (III) similarities and dissociations in fatty acid alterations between different psychiatric disorders. (Historical) epidemiological evidence links fatty acid intake to psychiatric disorder prevalence, corroborated by altered fatty acid concentrations measured in psychiatric patients. These fatty acid alterations are connected with other concomitant pathophysiological mechanisms, including biological stress (hypothalamic-pituitary-adrenal (HPA)-axis and oxidative stress), inflammation, and brain network structure and function. Metabolomics and lipidomics studies are underway to more deeply investigate this complex network of associated neurometabolic alterations. Supplementation of fatty acids as disease-modifying nutraceuticals has clinical potential, particularly add-on eicosapentaenoic acid (EPA) in depressed patients with markers of increased inflammation. However, by interpreting the observed fatty acid alterations as partly (mal)adaptive phenomena, we attempt to nuance translational expectations and provide new clinical applications for these novel neurometabolic insights, e.g., to predict treatment response or depression recurrence. In conclusion, placing fatty acids in context can contribute to further understanding and optimized treatment of psychiatric disorders, in order to diminish their overwhelming burden of disease.

RESUMO

OBJECTIVE: Cardiovascular disease (CVD) is the leading cause of death in severe psychiatric disorders (depression, schizophrenia). Here, we provide evidence of how the effects of oxidative stress on fatty acid (FA) and one-carbon (1-C) cycle metabolism, which may initially represent adaptive responses, might underlie comorbidity between CVD and psychiatric disorders. METHOD: We conducted a literature search and integrated data in a narrative review. RESULTS: Oxidative stress, mainly generated in mitochondria, is implicated in both psychiatric and cardiovascular pathophysiology. Oxidative stress affects the intrinsically linked FA and 1-C cycle metabolism: FAs decrease in chain length and unsaturation (particularly omega-3 polyunsaturated FAs), and lipid peroxidation products increase; the 1-C cycle shifts from the methylation to transsulfuration pathway (lower folate and higher homocysteine and antioxidant glutathione). Interestingly, corresponding alterations were reported in psychiatric disorders and CVD. Potential mechanisms through which FA and 1-C cycle metabolism may be involved in brain (neurocognition, mood regulation) and cardiovascular system functioning (inflammation, thrombosis) include membrane peroxidizability and fluidity, eicosanoid synthesis, neuroprotection and epigenetics. CONCLUSION: While oxidative-stress-induced alterations in FA and 1-C metabolism may initially enhance oxidative stress resistance, persisting chronically, they may cause damage possibly underlying (co-occurrence of) psychiatric disorders and CVD. This might have implications for research into diagnosis and (preventive) treatment of (CVD in) psychiatric patients.

RESUMO

BACKGROUND: Alterations in hypothalamic-pituitary-adrenal (HPA)-axis activity, fatty acid metabolism, and their relation have been associated with (recurrent) major depressive disorder (MDD), although conflicting findings exist. AIMS: To determine whether alterations in HPA-axis activity and fatty acids in recurrent MDD remain during remission (i.e. reflect a potential trait factor). Furthermore, to test the association between HPA-axis activity and fatty acids in patients versus controls. METHODS: We cross-sectionally compared 73 remitted unmedicated recurrent MDD patients with 46 matched never-depressed controls. Measurements included salivary cortisol and dehydroepiandrosterone sulfate (DHEAS) (awakening, evening, and after sad mood induction) and erythrocyte fatty acid parameters: (I) three main fatty acids [omega-3 docosahexaenoic acid (DHA), and the omega-3 eicosapentaenoic acid/omega-6 arachidonic acid (EPA/AA)-ratio], and (II) structural fatty acid indices [chain length, unsaturation and peroxidation]. RESULTS: Patients showed higher cortisol awakening responses (p = 0.006) and lower evening cortisol/DHEAS ratios (p = 0.044) compared to matched controls. Fatty acids did not differ between patients and controls, but HPA-axis indicators were significantly associated with fatty acid parameters in both groups (0.001 ≤ p ≤ 0.043). Patients and controls significantly differed in the relations between awakening DHEAS or cortisol/DHEAS ratios and fatty acid parameters, including unsaturation and peroxidation indices (0.001≤ p ≤ 0.034). Significance remained after correction for confounders. CONCLUSIONS: Our results further support alterations in HPA-axis activity, i.e. a lower baseline, but higher responsiveness of awakening cortisol, in remitted medication-free recurrent MDD patients. Furthermore, the relationship between HPA-axis and fatty acids showed significant differences in recurrent MDD patients versus controls. Prospective research is needed to determine the predictive value of this relationship for MDD recurrence.

RESUMO

BACKGROUND: Antipsychotics are effective drugs that are prescribed frequently for a large group of patients. However, they also have many side-effects which can lead ultimately to serious somatic complications. These complications fall into various categories: metabolic, cardiovascular, neurobiological, haematological, gastro-intestinal and urogenital. AIM: To make an inventory of the side-effects and advise on ways of monitoring and preventing them. method The multidisciplinary working group on somatic complications arising from the use of antipsychotics (Werkgroep Somatische Complicaties) has collected literature on the subject and has discussed it at a number of consensus meetings. results The most frequent somatic complications are described on the basis of specific risk profiles and advice is given on how to identify these complications and on how to treat them when necessary. It is essential to monitor, systematically and regularly, somatic complications arising from the use of antipsychotics; furthermore, polypharmacy should be avoided. The person ultimately responsible for this is the doctor who has prescribed the antipsychotics. In addition, it is important to draw patients' attention to the general rules for a healthy lifestyle: no smoking, a balanced diet and adequate exercise. CONCLUSION: It is very important that somatic complications should be monitored carefully and accurately. So far, the Netherlands has no official guidelines on ways to identify and treat somatic complications.

RESUMO

BACKGROUND: A better understanding of factors underlying antidepressant non-response may improve the prediction of which patients will respond to what treatment. Major depressive disorder (MDD) is associated with alterations in fatty acid metabolism, (neuro)inflammation and amygdala-reactivity. However, their mutual relations, and the extent to which they are associated with prospective antidepressant-response, remain unknown. PURPOSE: To test (I) alterations in (neuro)inflammation and its associations with fatty acid metabolism and amygdala-reactivity in MDD-patients compared to controls, and (II) whether these alterations are associated with prospective paroxetine response. METHODS: We compared 70 unmedicated MDD-patients with 51 matched healthy controls at baseline, regarding erythrocyte membrane omega-6 arachidonic acid (AA), inflammation [serum (high-sensitivity) C-reactive protein (CRP)], and in a subgroup amygdala-reactivity to emotional faces using functional magnetic resonance imaging (fMRI) (N=42). Subsequently, we treated patients with 12 weeks paroxetine, and repeated baseline measures after 6 and 12 weeks to compare non-responders, early-responders (response at 6 weeks), and late-responders (response at 12 weeks). RESULTS: Compared to controls, MDD-patients showed higher CRP (p=0.016) and AA (p=0.019) after adjustment for confounders at baseline. AA and CRP were mutually correlated (p=0.043). In addition, patients showed a more negative relation between AA and left amygdala-reactivity (p=0.014). Moreover, AA and CRP were associated with antidepressant-response: early responders showed lower AA (p=0.018) and higher CRP-concentrations (p=0.008) than non-responders throughout the study. CONCLUSION: Higher observed CRP and AA, their mutual association, and relation with amygdala-reactivity, are corroborative with a role for (neuro)inflammation in MDD. In addition, observed associations of these factors with prospective antidepressant-response suggest a potential role as biomarkers. Future studies in independent samples are needed to replicate and test the clinical applicability of these biological predictors for treatment response to result in a precision/personalized medicine approach for treatment.

RESUMO

Omega-3 polyunsaturated fatty acid (PUFA) supplementation has been proposed as (adjuvant) treatment for major depressive disorder (MDD). In the present meta-analysis, we pooled randomized placebo-controlled trials assessing the effects of omega-3 PUFA supplementation on depressive symptoms in MDD. Moreover, we performed meta-regression to test whether supplementation effects depended on eicosapentaenoic acid (EPA) or docosahexaenoic acid dose, their ratio, study duration, participants' age, percentage antidepressant users, baseline MDD symptom severity, publication year and study quality. To limit heterogeneity, we only included studies in adult patients with MDD assessed using standardized clinical interviews, and excluded studies that specifically studied perinatal/perimenopausal or comorbid MDD. Our PubMED/EMBASE search resulted in 1955 articles, from which we included 13 studies providing 1233 participants. After taking potential publication bias into account, meta-analysis showed an overall beneficial effect of omega-3 PUFAs on depressive symptoms in MDD (standardized mean difference=0.398 (0.114-0.682), P=0.006, random-effects model). As an explanation for significant heterogeneity (I(2)=73.36, P<0.001), meta-regression showed that higher EPA dose (ß=0.00037 (0.00009-0.00065), P=0.009), higher percentage antidepressant users (ß=0.0058 (0.00017-0.01144), P=0.044) and earlier publication year (ß=-0.0735 (-0.143 to 0.004), P=0.04) were significantly associated with better outcome for PUFA supplementation. Additional sensitivity analyses were performed. In conclusion, present meta-analysis suggested a beneficial overall effect of omega-3 PUFA supplementation in MDD patients, especially for higher doses of EPA and in participants taking antidepressants. Future precision medicine trials should establish whether possible interactions between EPA and antidepressants could provide targets to improve antidepressant response and its prediction. Furthermore, potential long-term biochemical side effects of high-dosed add-on EPA supplementation should be carefully monitored.

RESUMO

BACKGROUND: Major depressive disorder (MDD) has been associated with low dehydroepiandrosterone-sulphate (DHEAS), - particularly relative to high cortisol - although conflicting findings exist. Moreover, it is unclear whether low DHEAS is only present during the depressive state, or manifests as a trait that may reflect vulnerability for recurrence. Therefore, we longitudinally tested whether low DHEAS and high cortisol/DHEAS-ratio in recurrent MDD (I) reflects a trait, and/or (II) varies with depressive state. In addition, we tested associations with (III) previous MDD-episodes, (IV) prospective recurrence, and (V) effects of cognitive therapy. METHODS: At study-entry, we cross-sectionally compared morning and evening salivary DHEAS and molar cortisol/DHEAS-ratio of 187 remitted recurrent MDD-patients with 72 matched controls. Subsequently, patients participated in an 8-week randomized controlled cognitive therapy trial. We repeated salivary measures after 3 months and 2 years. We measured clinical symptoms during a 10-year follow-up. RESULTS: Remitted patients showed steeper diurnal DHEAS-decline (p<.005) and a flatter diurnal profile of cortisol/DHEAS-ratio (p<.001) than controls. We found no state-effect in DHEAS or cortisol/DHEAS-ratio throughout follow-up and no association with number of previous episodes. Higher morning cortisol/DHEAS-ratio predicted shorter time till recurrence over the 10-year follow-up in interaction with the effects of cognitive therapy (p<.05). Finally, cognitive therapy did not influence DHEAS or cortisol/DHEAS-ratio. CONCLUSIONS: Diurnal profiles of DHEAS and cortisol/DHEAS-ratio remain equally altered in between depressive episodes, and may predict future recurrence. This suggests they represent an endophenotypic vulnerability trait rather than a state-effect, which provides a new road to understand recurrent depression and its prevention.

RESUMO

PRL was measured radioimmunologically in plasma and cerebrospinal fluid (CSF) samples obtained simultaneously in 31 patients with various neurological or infectious, but non-endocrine diseases (group A), 12 patients (7 pregnant women and 5 newborns) with physiological hyperprolactinemia (group B),10 psychiatric patients with pharmacologically induced hyperprolactinemia (group C) 12 normoprolactinemic patients with pituitary adenoma and suprasellar extension (SSE) (group D), And 14 hyperprolactinemic patients with pituitary adenoma with and without SSE (group E). Plasma PRL and CSF PRL concentrations (ng/ml, mean and range in brackets) of the various groups were: group A, 6.2 (1.3-14.5) and 1.3 (0.6-4.7); group B, 85.2 (31-200) and 13.2 (3-28); group C, 54.3 (3.5-160) and 6.5 (0.7-18); group D, 17.2 (5.4-30) and 9.7 (2.7-34); and group E, 2,529 (115-10,000) and 1,449 (6-13,000). The plasma to CSF concentration ratios (mean and range in brackets) were: group A, 5.2 (1.4-13.0); group B, 7.0 (2.9-10.3); group C, 7.3( 3.9-11.3); group D, 2.6 (0.9-7.1); and group E, 10.9 (0.2-34.9). The ratio was greater than 3 in 87% of the non-tumor patients; in 42% of the tumor patients the ratio was less than 3. The correlation between plasma and CSF PRL levels of all 53 subjects without a pituitary tumor (groups A, B, and C) was positive (r=0.9097; P=0.00001); in the 26 tumor patients (groups D and E) the correlation was also positive (r=0.7141; P=0.00002). These results indicate that 1) PRL is a normal constituent of CSF, 2) the CSF PRL level is a function of the plasma level, 3) detectable, or even high, CSF PRL levels per se are not indicative in the presence of a pituitary tumor, with or without SSE, and 4) abnormally low ratios may be found in patients with a pituitary tumor with SSE.

RESUMO

Prolactinomas can be induced in rats by large doses of estrogens. Whether prolactinomas can be induced in humans by estrogens, however, is not known. This report describes the development of a prolactinoma in a man with previously normal plasma PRL levels after the administration of pharmacological doses of estrogen. The patient, a 26-yr-old male to female transsexual, took cyproterone acetate (100 mg/day, orally) and ethinyl estradiol (100 micrograms/day, orally) for 10 months and (surrepititiously) estradiol-17-undecanoate (100 mg, twice weekly, im) for about 6 of the 10 months. Plasma PRL levels rose from 0.05 to 5.20 U/L within 10 months (normal, 0.05-0.30 U/L). A computed tomographic scan showed a pituitary mass with suprasellar extension. After all estrogen therapy was discontinued, his plasma estradiol levels gradually declined from 2.8 to 0.77 nmol/L (normal, 0.04-0.12 nmol/L), but PRL levels rose further to 6.2 U/L. Bromocriptine treatment (2.5 mg twice daily) then was given. Plasma PRL fell gradually to 0.43 U/L and a computed tomographic scan after 5 months showed reduction in tumor size. The patient then discontinued bromocriptine treatment. Four months later his plasma estradiol level was normal, while plasma PRL had risen to 4.6 U/L, indicating autonomous PRL secretion. We conclude that 1) estrogen in pharmacological doses can induce prolactinomas in man; and 2) subjects treated with high doses of estrogen must, therefore, be surveyed for the development of such tumors.

RESUMO

BACKGROUND: Fatty acid research in schizophrenia has demonstrated an altered cell membrane phospholipid metabolism. Erythrocyte membrane phospholipid composition closest reflects that of neuronal membranes. METHODS: (Poly)(un)saturated fatty acid concentrations were measured in the erythrocyte membranes of 19, consecutively admitted, medicated young schizophrenic patients and then compared with matched control subjects. Psychiatric symptomatology was rated with the Positive and Negative Symptom Scale and Montgomery-Asberg Depression Rating Scale. Because diet, hormones, and cannabis influence fatty acid metabolism, we included these factors in our study. RESULTS: The most distinctive findings concerned the omega-3 series: C22:5 omega-3, C22:6 omega-3 (docosahexaenoic acid), and the sum of omega-3 fatty acids were significantly decreased. Interestingly, C20:4 omega-6 (arachidonic acid) was not lowered. In the omega-9 series, higher levels of C22:1 omega-9 and lower levels its elongation product, C24:1 omega-9 (nervonic acid), were found. Interestingly, the other arm of the desaturation-elongation sequence of C18:1 omega-9, C20:3 omega-9, was lower in patients. The total omega-9 fatty acid levels were also lower in patients. CONCLUSIONS: Significant differences in erythrocyte fatty acid composition were found. The differences were not due to diet or hormonal status and could not be explained by the medication or cannabis use. No consistent pattern emerged from the different fatty acid abnormalities and the clinical symptom scores.

RESUMO

X-linked adrenoleukodystrophy (X-ALD) is an inherited disorder of peroxisomal beta-oxidation associated with accumulation of saturated very long-chain fatty acids, which results in central and peripheral demyelination and in impaired function of adrenal cortex and testes. The phenotypic expression is highly variable, childhood cerebral ALD (CCALD) and adrenomyeloneuropathy (AMN) being the main variants. We explored the 30 Dutch kindreds well known to the Dutch X-ALD/AMN Study Group and phenotyped 77 male patients: 35 (46%) had AMN and 24 (31%) CCALD or adolescent cerebral ALD (AdolCALD). These percentages differ significantly from previous reports, in which 25 to 28% of the patients developed AMN and 53 to 57% CCALD or AdolCALD. Our findings indicate that--at least in the Netherlands--AMN may be the most frequent phenotype of X-ALD.

RESUMO

Fourteen mildly hyperprolactinemic women and 14 matched controls were compared with respect to biographical data, self-reported emotional and somatic well-being, and cortisol production. The patients had significantly more often experienced a separation from their parents in childhood. No differences were found for cortisol levels and emotional and somatic well-being. Future studies also should focus on personality, coping, and defense mechanisms in order to explain these contrasting findings.

RESUMO

Major depressive disorders (MDD) and cardiovascular disease are mutually associated. They share signs and symptoms of the "metabolic syndrome". Two observations that may be causally related with the metabolic syndrome and therefore with both MDD and cardiovascular disease are a decrease in omega-3 polyunsaturated fatty acids (PUFAs) and a rise in plasma homocysteine (tHcy) levels. Both the rise in tHcy and the decrease in omega-3 PUFAs may be associated with enhanced lipid peroxidation. We exploratively studied 44 randomly chosen patients out of a cohort of 134 patients with the recurrent form of MDD (MDD-R). We measured tHcy levels together with saturated FAs, monounsaturated fatty acids (MUFAs) and PUFAs of the omega-3, omega-6 and omega-9 series in plasma and erythrocytes. Levels were compared with laboratory reference values. The main findings were a decrease in the erythrocytes of C22:5omega-3, C22:6omega-3, C24:1omega-9 and C20:3omega-9 and in the plasma a decrease in C24:1omega-9 and C20:3omega-9. The only significant association we found was between the total of omega-6 fatty acids and plasma tHcy. The FA alterations were found in patients although most of them were clinically recovered, suggesting that the alterations may represent a biological" trait" marker for recurrent depression.

RESUMO

AIMS: This study was set up to determine the long term ocular and systemic sequelae in patients with severe congenital toxoplasmosis. METHODS: Cross sectional and retrospective study of 17 patients with severe congenital toxoplasmosis. RESULTS: In addition to chorioretinitis (100%), the most common abnormal ocular features were optic nerve atrophy (83%), visual acuity of less than 0.1 (85%), strabismus, and microphthalmos. In 50% of cases we observed iridic abnormalities and about 40% developed a cataract. Overt endocrinological disease, diagnosed in five of 15 patients, included panhypopituitarism (n = 2), gonadal failure with dwarfism (n = 1), precocious puberty with dwarfism and thyroid deficiency (n = 1), and diabetes mellitus and thyroid deficiency (n = 1). The observed endocrinological involvement was associated in all cases with obstructive hydrocephalus with a dilated third ventricle and optic nerve atrophy. CONCLUSION: The recognition of long term ocular, neurological, and endocrinological sequelae of congenital toxoplasmosis is important for medical management of these severely handicapped patients.

RESUMO

In 16 consecutive patients with clinically suspected and biochemically proven X-linked adrenoleukodystrophy (X-ALD), total delay (interval between onset of symptoms and diagnosis) and specialist delay (interval between referral to a specialist and diagnosis) were determined. All patients previously were unaware of the existence of X-ALD in their families. From the time of onset of symptoms attributable to this disease until diagnosis, mean total delay was 9.9 (range 1-33) years and mean specialist delay was 8.4 (range 0-33) years. Three patients who presented with adrenocortical insufficiency had mean total and specialist delays of 17.3 (range 9-33) years. Five patients with an initial diagnosis of multiple sclerosis had mean total and specialist delays of 12.8 (range 5-25) and 11.2 (range 1-23) years, respectively. In 12 patients with adrenomyeloneuropathy--the second most frequent phenotype of X-ALD--mean total delay was 11.0 (range 2-33) years and mean specialist delay 9.1 (range 0-33) years. Since 1981 X-ALD can be reliably diagnosed on the basis of elevated levels of very long chain fatty acids in plasma and/or cultured fibroblasts. The delays therefore must have been due to the unfamiliarity with the clinical manifestations and diagnostic possibilities of this disease. Once X-ALD is diagnosed, dietary treatment and/or bone marrow transplantation may be considered. Genetic counseling should be performed, and screening of other family members is essential for the early identification of affected relatives.

RESUMO

A triplet pregnancy is reported in an acromegalic woman with hypothalamic amenorrhoea treated with pulsatile gonadotrophin-releasing hormone (GnRH). The patient was on bromocriptine medication and had slightly elevated growth hormone (GH) and somatomedin-C (Sm-C) levels. This probably accounted for the conception of triplets in the first stimulation cycle.

RESUMO

OBJECTIVE: To compare self-reports of immune-related diseases in diethylstilbestrol (DES) daughters and controls. Prenatal exposure to DES has been associated with several malformations in the lower genital tract, a higher prevalence of adenosis, and increased risk of clear cell adenocarcinoma, and estrogen-dependent tumors. Lately, reports have been published indicating a link between DES exposure and alterations in the immune system. The present study focuses on the possible clinical consequences of an affected immune system. STUDY DESIGN: DES daughters (n=170) and control women (n=123) completed questionnaires containing lists of immune-related diseases, specified into three categories (i) allergies, (ii) auto-immune disorders, and (iii) infectious diseases. RESULTS: DES daughters reported significantly more disease conditions than the controls. Analyses for separate disease categories (allergies, auto-immune disorders, infectious disease), yielded a statistically significant difference only for infectious disease. Within this last category, two infectious diseases yielded highly significant differences: bladder infection and measles. CONCLUSION: The present findings suggest that DES daughters are at higher risk of developing immune-related disease states.

RESUMO

A case of extremely painful swelling of the breasts following a reduction mammaplasty is presented. There were no signs of an abscess or hematoma. A milky white fluid due to galactorrhea was evacuated at operation, and further galactorrhea was inhibited by medication. The pathogenesis of galactorrhea and its treatment are discussed.
