RESUMO

RESEARCH QUESTION: What are the differences in menstrual blood lymphocytes between controls, patients with recurrent pregnancy loss (RPL) and patients with unexplained infertility (uINF)? DESIGN: Prospective study including 46 healthy controls, 28 RPL and 11 uINF patients. A feasibility study compared lymphocyte compositions of endometrial biopsies and menstrual blood collected during the first 48 h of menstruation in seven controls. In all patients, peripheral and menstrual blood from the first and subsequent 24 h were analysed separately by flow cytometry, focusing on the main lymphocyte populations and natural killer (NK) cell subsets. RESULTS: The first 24 h of menstrual blood resembles the uterine immune milieu as tested by endometrial biopsy. RPL patients showed significantly higher menstrual blood CD56+ NK cell numbers than controls (mean ± SD: 31.13 ± 7.52% versus 36.73 ± 5.4%, P = 0.002). Menstrual blood CD56dimCD16bright NK cells within the CD56+ NK cell population were decreased in RPL (16.34 ± 14.65%, P = 0.011) and uINF (15.7 ± 5.91%, P = 0.02) patients versus control (20.42 ± 11.53%). uINF patients had the lowest menstrual blood CD3+ T cell counts (38.81 ± 5.04%, control versus uINF: P = 0.01) and cytotoxicity receptors NKp46 and NKG2D on CD56brightCD16dim cells were higher in uINF (68.12 ± 11.84%, P = 0.006; 45.99 ± 13.83%, P = 0.01, respectively) and RPL (NKp46: 66.21 ± 15.36%, P = 0.009) patients versus controls. RPL and uINF patients had higher peripheral CD56+ NK cell counts versus controls (11.42 ± 4.05%, P = 0.021; 12.86 ± 4.29%, P = 0.009 versus 8.4 ± 3.5%). CONCLUSIONS: Compared with controls, RPL and uINF patients had a different menstrual blood-NK-subtype profile, indicating an altered cytotoxicity. In future studies, this non-invasive analysis might enable identification and monitoring of patients receiving immunomodulatory medications.

RESUMO

INTRODUCTION: Depressive episodes are often prevalent among patients with bipolar disorder, but little is known regarding the differential patterns of development over time. We aimed to determine and characterize trajectories of depressive symptoms among adults with bipolar disorder during 6 months of systematic treatment. METHODS: The pragmatic clinical trial, Bipolar Clinical Health Outcomes Initiative in Comparative Effectiveness (CHOICE), randomized 482 outpatients with bipolar disorder to lithium or quetiapine. Depressive symptoms were rated at up to 9 visits using the Montgomery-Asberg Depression Rating Scale (MADRS). Growth mixture modeling was utilized to identify trajectories and multinomial regression analysis estimated associations with potential predictors. RESULTS: Four distinct trajectories of depressive symptoms were identified. The responding class (60.3%) with a rapid reduction and subsequent low level; the partial-responding class (18.4%) with an initial reduction followed by an increase during the remaining weeks; the fluctuating class (11.6%) with a fluctuation in depressive symptoms; and the non-responding class (9.7%) with sustained moderate-severe depressive symptoms. Bipolar type I predicted membership of the non-responding class and randomization to quetiapine predicted membership of either the responding or the non-responding class. CONCLUSION: Approximately 30% experienced a partial or fluctuating course, and almost 10% had a chronic course with moderate-severe depression during 6 months. Patients diagnosed with bipolar type 1 had higher risk of being categorized into a class with a worse outcome. While no differences in average overall outcomes occurred between the lithium and quetiapine groups, trajectory analysis revealed that the lithium group had more variable courses.

RESUMO

BACKGROUND: Auditory hallucinations represent a key diagnostic feature of schizophrenia and one of the most frequent and debilitating psychotic symptoms. However, little is known regarding their long-term trajectories. METHODS: We included 496 patients with a first schizophrenia-spectrum disorder. Patients were at baseline and after one, two, five, and ten years asked for auditory hallucinations, scoring from 0 ("None") to 5 ("Severe: Voices occur often every day"). We performed latent class growth analyses to identify trajectories of auditory hallucinations and multinomial logistic regression analyses to estimate predictors of trajectory membership. RESULTS: We identified three trajectories of auditory hallucinations. The Low-Decreasing class (77%) had the lowest mean score at baseline (mean score = 2.1). The score improved within the first year (mean score = 0.5) and stayed low (mean score = 0 after ten years). The High-Fluctuating class (10%) improved during the first two years from a mean score of 3.0 to 1.0, but increased after five and ten years (mean score = 2.4). The High-Increasing class (13%) started at a high level (mean score = 3.5), improved a little after one year (mean score = 3.0), but increased to a mean score of 4.8 after ten years. Alcohol misuse and longer duration of untreated psychosis were associated with increased odds of being in the High-Increasing compared to the Low-Decreasing class. CONCLUSIONS: The majority of patients with schizophrenia-spectrum disorder improved on auditory hallucinations during the first ten years, but almost one out of four had a fluctuating course with 13% experiencing an increase to severe and daily auditory hallucinations after ten years.

RESUMO

In this case report, a germ line genome project identified a pathogenic variant in TP53 in a three-year-old girl diagnosed with rhabdomyosarcoma. The variant causes the cancer predisposition syndrome Li-Fraumeni syndrome (LFS). The girl's family was genetically counselled, and the same variant was identified in her mother and sister. The family was afterwards offered surveillance according to national guidelines. With this report, we want to focus on cancer predisposition syndromes and to discuss the benefits regarding surveillance of children with LFS.

RESUMO

BACKGROUND: Suicidal ideation is a frequent and difficult-to-treat clinical challenge among patients with major depressive disorder (MDD). However, little is known regarding the differential development during antidepressant treatment and whether some patients may suffer from persistent suicidal ideation. METHODS: Among 811 patients with Schedules for Clinical Assessment in Neuropsychiatry (SCAN)-verified MDD from 2004-2007 assessed weekly for 12 weeks of escitalopram or nortriptyline antidepressant treatment, we applied item response theory to integrate a suicidality score based on 3 rating scales. We performed latent growth mixture modeling analysis to empirically identify trajectories. Multinomial logistic regression analyses estimated associations with potential predictors. RESULTS: We identified 5 distinct classes of suicidal ideation. The Persistent-low class (53.7%) showed no suicidal ideation whereas the Persistent-high class (9.8%) had high suicidal ideation throughout 12 weeks. Two classes showed a fluctuating course: the Fluctuating class (5.2%) ended at a low level of suicidal ideation, whereas the Slow-response-relapse class (4.8%) initially responded slowly but then experienced a large increase to a high level of suicidal ideation after 12 weeks. The Fast-response class (26.5%) had a high baseline severity similar to the Persistent-high class but responded quickly within a few weeks and remained at a low level. Previous suicide attempts and higher mood symptom severity were associated with worse suicidal ideation trajectories, whereas living with a partner showed a trend toward better response. CONCLUSION: Approximately 1 of 5 patients with MDD showed high or fluctuating suicidal ideation despite antidepressant treatment. Studies should investigate whether suicidal ideation may persist for longer periods and more targeted treatment possibilities. TRIAL REGISTRATION: ISRCTN​​ identifier: ISRCTN03693000​​​​.

RESUMO

INTRODUCTION: Suicidal ideation occurs frequently among individuals with bipolar disorder; however, its course and persistence over time remains unclear. We aimed to investigate 6-months trajectories of suicidal ideation among adults with bipolar disorder. METHODS: The Bipolar CHOICE study randomized 482 outpatients with bipolar disorder to 6 months of lithium- or quetiapine-based treatment including other psychotropic medications as clinically indicated. Participants were asked at 9 visits about suicidal ideation using the Concise Health Risk Tracking scale. We performed latent Growth Mixture Modelling analysis to empirically identify trajectories of suicidal ideation. Multinomial logistic regression analyses were applied to estimate associations between trajectories and potential predictors. RESULTS: We identified four distinct trajectories. The Moderate-Stable group represented 11.1% and was characterized by constant suicidal ideation. The Moderate-Unstable group included 2.9% with persistent thoughts about suicide with a more fluctuating course. The third (Persistent-low, 20.8%) and fourth group (Persistent-very-low, 65.1%) were characterized by low levels of suicidal ideation. Higher depression scores and previous suicide attempts (non-significant trend) predicted membership of the Moderate-Stable group, whereas randomized treatment did not. LIMITATIONS: No specific treatments against suicidal ideation were included and suicidal thoughts may persist for several years. CONCLUSION: More than one in ten adult outpatients with bipolar disorder had moderately increased suicidal ideation throughout 6 months of pharmacotherapy. The identified predictors may help clinicians to identify those with additional need for treatment against suicidal thoughts and future studies need to investigate whether targeted treatment (pharmacological and non-pharmacological) may improve the course of persistent suicidal ideation.
