MANAGEMENT OF DEPRESSION IN THE PRESENCE OF PAIN SYMPTOMS

Somatic illness is frequently associated with depression and anxiety and major depression significantly increases risk of severe medical conditions, e.g. cardiovascular illness. One of the most frequent comorbidities is that of depression and pain. Alterations in or adrenergic and serotonergic neurotransmissions in the central nervous system have been implicated in the joint pathophysiology of depression and chronic pain. Antidepressants, alone or in combination with psychotherapy, are an effective treatment option in such cases. The newer dual action antidepressants (milnacipran, venlafaxine, duloxetine) acting specifically on both noradrenergic and serotonergic neurotransmitter systems are presumably more reliable in pain management. So far, the most extensively studied drug has been duloxetine. Twelve randomized placebo-controlled trials with the total number of 4,108 patients suffering from pain associated with major depressive disorder suggested consistent analgesic efficacy of duloxetine, especially in fibromyalgia and peripheral neuropathic pain

Lifetime Bipolar Disorder comorbidity and related clinical characteristics in patients with primary Obsessive Compulsive Disorder: a report from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS)

IntroductionBipolar disorder (BD) and obsessive compulsive disorder (OCD) are prevalent, comorbid, and disabling conditions, often characterized by early onset and chronic course. When comorbid, OCD and BD can determine a more pernicious course of illness, posing therapeutic challenges for clinicians. Available reports on prevalence and clinical characteristics of comorbidity between BD and OCD showed mixed results, likely depending on the primary diagnosis of analyzed samples.MethodsWe assessed prevalence and clinical characteristics of BD comorbidity in a large international sample of patients with primary OCD (n = 401), through the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS) snapshot database, by comparing OCD subjects with vs without BD comorbidity.ResultsAmong primary OCD patients, 6.2% showed comorbidity with BD. OCD patients with vs without BD comorbidity more frequently had a previous hospitalization (p < 0.001) and current augmentation therapies (p < 0.001). They also showed greater severity of OCD (p < 0.001), as measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS).ConclusionThese findings from a large international sample indicate that approximately 1 out of 16 patients with primary OCD may additionally have BD comorbidity along with other specific clinical characteristics, including more frequent previous hospitalizations, more complex therapeutic regimens, and a greater severity of OCD. Prospective international studies are needed to confirm our findings.Peer reviewe

MAY PPAR GAMMA BE SIGNIFICANT IN BIPOLAR DISORDER ONLY IN THE PRESENCE OF METABOLIC SYNDROME?

Background: Peroxisome proliferator-activated receptor γ (PPARγ) has a key role in regulating both neurogenesis and various metabolic processes, including adipogenesis and glucose homeostasis. In this study, it was aimed to compare the serum PPARγ levels and metabolic syndrome (MetS) parametres of patients with Bipolar Disorder (BD) diagnosed manic-depressive-euthymic episodes with those of healthy subjects. Subjects and Methods: We included 121 male patients with BD type I, 44 in mania, 35 in depression and 42 in euthymic state, and 41 healthy controls. Serum PPARγ levels, inflammation indicators (CRP, neutrophil, leukocyte, and albumin) and Mets parametres were measured. Results: There were no statistically significant differences between the groups in terms of PPARγ values. PPARγ serum level is highest in the control group and then euthymic, manic and depressive episodes continue to decrease, respectively. However, there was a significant difference between the depressive group with MetS and without MetS in terms of serum PPARγ levels. A statistically significant correlation was found between PPARγ and the other serum markers such as low-density lipoprotein (p=0.022), HbA1c (p=0.002), neutrophils levels (0.001), white blood cell (p=0.025), and clinical features such as age at first treatment (p=0.024), age at first episode (p=0.039), and smoking (0.013). Conclusions: We suggest that PPARγ may be a key factor in the BD depressive group with MetS. Not finding any relationship between the PPARγ levels and the episode of BD may be related with the absence of MetS in the individuals. MetS parametres must also be considered if PPARγ is to be evaluated in the future investigations

The role of gender in a large international OCD sample: A Report from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS) Network

Introduction: Obsessive-compulsive disorder (OCD) is characterized by a range of phenotypic expressions. Gender may be a relevant factor in mediating the disorder's heterogeneity. The aim of the present report was to explore a large multisite clinical sample of OCD patients, hypothesizing existing demographic, geographical and clinical differences between male and female patients with OCD.&amp; nbsp;Methods: Socio-demographic and clinical variables of 491 adult OCD outpatients recruited in the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS) network were investigated with a retrospective analysis on a previously gathered set of data from eleven countries worldwide. Patients were assessed throughstructured clinical interviews, the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Montgomery-Asberg Depression Rating Scale (MADRS) and the Self-rating Depression Scale (SDS).&amp; nbsp;Results: Among females, adult onset (&gt; 18 years old) was significantly over-represented (67% vs. 33%, p &lt; 0.005), and females showed a significantly older age at illness onset compared with males (20.85 +/- 10.76 vs. 17.71 +/- 8.96 years, p &lt; 0.005). Females also had a significantly lower education level than males (13.09 +/- 4.02 vs. 13.98 +/- 3.85 years; p &lt; 0.05), a significantly higher rate of being married (50.8% vs. 33.5%; p &lt; 0.001) and a higher rate of living with a partner (47.5% vs. 37.6%; p &lt; 0.001) than males. Nonetheless, no significant gender dif-ferences emerged in terms of the severity of OCD symptoms nor in the severity of comorbid depressive symptoms. No predictive effect of gender was found for Y-BOCS, MADRS and SDS severity.&amp; nbsp;Discussion/Conclusions.: Our findings showed significant differences between genders in OCD. A sexually dimorphic pattern of genetic susceptibility may have a crucial role to OCD clinical heterogeneity, potentially requiring different specific therapeutic strategies. Further research is warranted to validate gender as an important determinant of the heterogeneity in OCD

Predictors of remission from PTSD symptoms after sexual and non-sexual trauma in the community: A mediated survival-analytic approach.

Epidemiological data on the chronicity of posttraumatic stress disorder (PTSD) symptoms in relation to trauma type and underlying pathways are rare. The current study explored how PTSD symptoms change over time across different trauma types and examined mediators of their persistence. A trauma-exposed community sample, whereof approximately one quarter met diagnostic criteria for PTSD, provided retrospective data on the duration of PTSD symptoms. Those who remitted and those who had not at the time of assessment were compared regarding worst trauma, symptom severity, comorbidity, demographic and treatment-seeking variables. Time to remission was estimated using Cox proportional hazard models including candidate predictors of remission. A mediated survival analysis was used to explore indirect pathways that explain trauma-specific differences in remission times. Both the full sample and PTSD subgroup were analyzed separately. Overall, lower socio-economic status, lifetime and childhood sexual trauma, symptom severity, comorbid depression and past treatment were associated with non- and longer remissions. PTSD avoidance symptoms and comorbid depression were found to mediate longer remission times after lifetime or childhood sexual trauma. Our findings provide insight into the mechanisms and complicating factors of remission from PTSD symptoms after trauma, which might have important implications for therapeutic interventions
