Immune system markers may predict affective disorder treatment response, but whether an overall immune system marker predicts bipolar disorder treatment effect is unclear.
Bipolar CHOICE (N = 482) and LiTMUS (N = 283) were similar comparative effectiveness trials treating patients with bipolar disorder for 24 weeks with four different treatment arms (standard-dose lithium, quetiapine, moderate-dose lithium plus optimised personalised treatment (OPT) and OPT without lithium). We performed secondary mixed effects linear regression analyses adjusted for age, gender, smoking and body mass index to investigate relationships between pre-treatment white blood cell (WBC) levels and clinical global impression scale (CGI) response.
Compared to participants with WBC counts of 4.5–10 × 109/l, participants with WBC < 4.5 or WBC ≥ 10 showed similar improvement within each specific treatment arm and in gender-stratified analyses.
An overall immune system marker did not predict differential treatment response to four different treatment approaches for bipolar disorder all lasting 24 weeks.
UHV-CVD growth based on a deuterium stabilized Sn hydride and digermane produces Ge-Sn alloys with tunable bandgaps. The Ge1−xSnx (x=2–20 at.%) alloys are deposited on Si (100) and exhibit superior crystallinity and thermal stability compared with MBE grown films. Composition, crystal and electronic structure, and optical and vibrational properties are characterized by RBS, low energy SIMS, high resolution electron microscopy TEM, x-ray diffraction, as well as Raman and IR spectroscopies. TEM studies reveal epitaxial films with lattice constants between those of Ge and Sn. X-ray diffraction shows well-defined (004) peaks and rocking curves indicate a tightly aligned spread of the crystal mosaics. Resonance Raman indicate a E1 bandgap reduction relative to Ge, consistent with a decrease of the E2 critical point observed in spectroscopic ellipsometry. IR transmission spectra indicate an increase in absorption with increasing Sn content consistent with a decrease of the direct bandgap.
Introduction: Concomitant psychotropic medication (CPM) treatment is common in persons with major depression (MDD). However, relationships with patient characteristics and response to treatment are unclear.
Methods: Participants with nonpsychotic MDD (N=2682) were treated with citalopram, 20–60 mg/day. Sociodemographic, clinical, and treatment outcome characteristics were compared between those using CPMs at study entry or during up to 14 weeks of citalopram treatment, and non-users.
Results: About 35% of participants used a CPM. Insomnia was the predominant indication (70.3%). CPM users were more likely to be seen in primary care settings (69.3% versus 30.7%), be white, of non-Hispanic ethnicity, married, and have a higher income, private insurance, and certain comorbid disorders. CPM users had greater depressive severity, poorer physical and mental functioning, and poorer quality of life than non-users. Response and remission rates were also lower. CPM users were more likely to achieve ≥50 mg/day of citalopram, to report greater side effect intensity, and to have serious adverse events, but less likely to be intolerant of citalopram.
Conclusion: CPMs are associated with greater illness burden, more Axis I comorbidities (especially anxiety disorders), and lower treatment effectiveness. This suggests that CPM use may identify a more difficult to treat population that needs more aggressive treatment.
