Background: Whether response to antidepressants is related to the risk of developing type 2 diabetes mellitus (T2DM) in adolescents with depression remains unknown., Methods: This study used the Taiwan National Health Insurance Research Database to enroll 1739 adolescents with antidepressant-resistant depression, 6956 with antidepressant-responsive depression, and 6956 controls between 2001 and 2010, with an end-of-2011 follow-up. Physician-diagnosed T2DM was identified at follow-up. T2DM-related risk factors, namely hypertension, dyslipidemia, and obesity, were assessed and controlled for as confounding factors., Results: Adolescents with antidepressant-resistant depression (hazard ratio [HR], 95 % confidence interval [CI]: 4.62, 2.75-7.75) and those with antidepressant-responsive depression (HR, 95 % CI: 3.06, 1.98-4.72) had a higher risk of developing T2DM at follow-up than did the control group. Those with antidepressant-resistant depression were more likely to receive a diagnosis of T2DM (HR, 95 % CI: 1.51, 1.04-2.19) later in life than were those with antidepressant-responsive depression., Discussion: Clinicians should closely monitor factors related to T2DM, such as fasting blood sugar, in high-risk populations, especially in adolescents with antidepressant-resistant depression., Competing Interests: Conflict of interest No conflict of interest., (Copyright © 2023 Elsevier B.V.

Background: Studies have indicated that parental depression was slightly related to the increased risk of offspring attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). However, the association between exposure to parental depression at different neurodevelopmental stages (i.e., perinatal or postnatal period) and subsequent ADHD and ASD development remained uncertain., Method: 708,515 children born between 2001 and 2008 were screened for ADHD and ASD based on ICD-9-CM codes of 314 and 299 given by psychiatrists from their birth to the end of 2011. Paternal and maternal depression was separately assessed during five periods, namely those before pregnancy (pre-pregnancy), during pregnancy (perinatal), and <1, 1-3, and >3 years after childbirth (postnatal). Cox regression analyses were performed., Results: Both paternal and maternal depression occurring in the pre-pregnancy, perinatal and postnatal periods were significantly associated with subsequent ADHD and ASD in the offspring, with hazard ratios between 1.42 (95% confidence interval [CI]: 1.35-1.49) and 2.25 (2.09-2.41). The chronicity and additive effect of paternal and maternal depression were related to increased risks of offspring ADHD and ASD. The effects of maternal depression were stronger than the effects of paternal depression for offspring ADHD (HR: 1.35, 95% CI: 1.27-1.45) and ASD (HR: 1.23, 95% CI: 1.05-1.46) risks., Conclusion: Both paternal depression and maternal depression in the pre-pregnancy, perinatal and postnatal periods increases offspring ADHD and ASD risks, and these risks increase further with increases in the duration of parental depression and with the additive effect of parental and maternal depression., (Copyright © 2020.

Background: Studies have suggested that psychiatric comorbidities have major effects on antidepressant resistance in adult patients with major depressive disorder (MDD). However, the association between psychiatric comorbidities and antidepressant resistance remains unclear in adolescents with MDD., Methods: A total of 10,624 adolescents with MDD were selected from the Taiwan National Health Insurance Research Database between 2001 and 2010 and followed for one year. Treatment-resistant depression (TRD) was defined as unresponsiveness to at least two antidepressants, and treatment resistant tendency was defined as unresponsiveness to the first antidepressant. Psychiatric comorbidities, such as anxiety disorders, substance use disorders, and attention deficit hyperactivity disorder (ADHD), were assessed as confounding factors., Results: In our study, only 1.7% (n = 184) of adolescents with MDD met the TRD criteria but 23.3% (n = 2480) were classified as exhibiting treatment resistant tendency. Anxiety disorders (OR: 2.34, 95% CI: 1.73-3.16) and substance use disorders (OR: 2.41, 95% CI: 1.28-4.54) exhibited a correlation with TRD, and ADHD (OR: 1.34, 95% CI: 1.08-1.66) was associated with treatment resistant tendency., Conclusions: Approximately one-fourth of adolescents with MDD respond poorly to the first antidepressant treatment. The psychiatric comorbidities of anxiety disorders, substance use disorders, and ADHD may increase the risk of treatment resistance in adolescents with MDD., (Copyright © 2019 Elsevier B.V.

Background: Reduced brain serotonin transporter (SERT) has been demonstrated in bipolar disorder (BD). The aim of this study was to explore the potential role of cytokines on reduced SERT in BD., Methods: Twenty-eight BD type I patients and 28 age- and gender-matched healthy controls (HCs) were recruited. Single photon emission computed tomography with the radiotracer 123I ADAM was used for SERT imaging. Regions of interest included the midbrain, thalamus, putamen and caudate. Seven cytokines, including tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-1α (IL-1α), IL-1β, IL-4, IL-6 and IL-10, were measured using an enzyme linked immune-sorbent assay., Results: SERT availability in the midbrain and caudate was significantly lower in BD compared to HCs. IL-1β was significantly lower, whereas IL-10 was significantly higher in BD compared to HCs. Multiple linear regression analyses revealed that there were associations between cytokines, IL-1α, IL-1β, IL-6 and SERT availability in the midbrain but not in the thalamus, putamen and caudate. Furthermore, linear mixed effect analyses demonstrated that these associations were not different between HCs and BD., Conclusion: While many cytokines have been proposed to be important in the pathophysiology of BD, our results demonstrated that significant associations between cytokines and SERT availability may explain the role of cytokines in mood regulation. However, these associations were not different between HCs and BD, which imply the role of these cytokines is not specific for BD., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Backgrounds: Several cross-sectional studies suggested a link between endometriosis and mood disorders. However, the temporal association between endometriosis and mood disorders (depression and anxiety disorders) is still unclear., Methods: Using the Taiwan National Health Insurance Research Database, 10,439 women with endometriosis and 10,439 (1:1) age-/sex-matched controls between 1998 and 2009 were enrolled, and followed up to the end of 2011. Those who developed depression or anxiety disorders during the follow-up were identified., Results: Women with endometriosis had an increased risk of developing major depression (hazard ratio [HR]: 1.56, 95% confidence interval [CI]:1.24-1.97), any depressive disorder (HR: 1.44, 95% CI: 1.25-1.65), and anxiety disorders (HR: 1.44, 95% CI: 1.22-1.70) in later life compared to those without endometriosis. Stratified by age group, women with endometriosis aged <40 years and those aged ≧40 years were both prone to developing major depression (HR: 1.52, 95% CI: 1.15-1.99; HR: 1.69, 95% CI: 1.09-2.62), any depressive disorder (HR: 1.43, 95% CI: 1.21-1.69; HR: 1.45, 95% CI: 1.13-1.56), and anxiety disorders (HR: 1.39, 95% CI: 1.14-1.71; HR: 1.53, 95% CI: 1.15-2.04)., Limitation: the incidence of depression and anxiety disorders may be underestimated since only those who sought medical consultation and help would be enrolled in our study., Conclusion: Endometriosis was associated with an elevated likelihood of developing depression and anxiety disorders. Further studies may be required to investigate the underlying pathophysiology between endometriosis and both depression and anxiety disorders., (Copyright © 2015 Elsevier B.V. All rights reserved.)
