Sleep disturbances in early clinical stages of psychotic and bipolar disorders: A meta-analysis

Objective: To provide a qualitative view and quantitative measure of sleep disturbances across and between early stages – clinical ultra high-risk and first episode – of psychotic and bipolar disorders. Methods: Electronic databases (PubMed, Cochrane, Embase, PsychINFO) were searched up to March 2021 for studies comparing sleep measures between individuals with an early stage and controls. Standard mean deviations (Cohen’s d effect sizes) were calculated for all comparisons and pooled with random-effects models. Chi-square tests were used for direct between-subgroups (ultra high-risk vs first episode) comparisons of standard mean deviations. The effects of age, sex ratio, symptoms and treatment were examined in meta-regression analyses. Results: A database search identified 13 studies that contrasted sleep measures between individuals with an early stage ( N = 537) and controls ( N = 360). We observed poorer subjective sleep quality (standard mean deviation = 1.32; 95% confidence interval, [1.01, 1.62]), shorter total sleep time (standard mean deviation =−0.44; 95% confidence interval, [−0.67, −0.21]), lower sleep efficiency (standard mean deviation = −0.72; 95% confidence interval, [−1.08, −0.36]), longer sleep onset latency (standard mean deviation = 0.75; 95% confidence interval, [0.45, 1.06]) and longer duration of wake after sleep onset (standard mean deviation = 0.49; 95% confidence interval, [0.21, 0.77]) were observed in early stages compared to controls. No significant differences were observed for any of the reported electroencephalographic parameters of sleep architecture. No significant between-subgroups differences were observed. Meta-regressions revealed a significant effect of the age and the antipsychotic status on subjective measures of sleep. Conclusion: The early stage population presents with significant impairments of subjective sleep quality continuity, duration and initiation. Systematic assessments of sleep in early intervention settings may allow early identification and treatment of sleep disturbances in this population.

Schizotypy, Lifestyle Behaviors, and Health Indicators in a Young Adult Sample

Problematic lifestyle behaviors and high rates of physical illness are well documented in people with schizophrenia, contributing to premature mortality. Yet, there is a notable absence of research examining general lifestyle and health issues in participants at risk for psychosis. This form of research may help identify concerns that exist during prodromal periods related to future outcomes. Accordingly, the current study examined lifestyle and health in a nonclinical sample of 530 young adults with varying levels of schizotypy. Increasing symptom severity was associated with greater somatic symptoms and poorer sleep quality across positive, negative, and disorganized domains. Elevated negative and disorganized symptoms were associated with significantly reduced health-related quality of life, while evidence for reduced engagement in health behaviors was largely limited to those with elevated negative schizotypy. No relationships emerged between symptom presentation/severity and body mass index or substance use, although zero-order correlations suggested an association between disorganized schizotypy and nicotine use. The pattern of relationships in the current study was consistent with findings from the ultra-high risk and clinical literature suggesting that lifestyle and health concerns may exist on a continuum with psychosis. Future research should seek to clarify if these patterns are associated with long-term physical or mental health outcomes.

Inflammation and JNK's Role in Niacin-GPR109A Diminished Flushed Effect in Microglial and Neuronal Cells With Relevance to Schizophrenia

Schizophrenia is a neuropsychiatric illness with no single definitive aetiology, making its treatment difficult. Antipsychotics are not fully effective because they treat psychosis rather than the cognitive or negative symptoms. Antipsychotics fail to alleviate symptoms when patients enter the chronic stage of illness. Topical application of niacin showed diminished skin flush in the majority of patients with schizophrenia compared to the general population who showed flushing. The niacin skin flush test is useful for identifying patients with schizophrenia at their ultra-high-risk stage, and understanding this pathology may introduce an effective treatment. This review aims to understand the pathology behind the diminished skin flush response, while linking it back to neurons and microglia. First, it suggests that there are altered proteins in the GPR109A-COX-prostaglandin pathway, inflammatory imbalance, and kinase signalling pathway, c-Jun N-terminal kinase (JNK), which are associated with diminished flush. Second, genes from the GPR109A-COX-prostaglandin pathway were matched against the 128-loci genome wide association study (GWAS) for schizophrenia using GeneCards, suggesting that G-coupled receptor-109A (GPR109A) may have a genetic mutation, resulting in diminished flush. This review also suggests that there may be increased pro-inflammatory mediators in the GPR109A-COX-prostaglandin pathway, which contributes to the diminished flush pathology. Increased levels of pro-inflammatory markers may induce microglial-activated neuronal death. Lastly, this review explores the role of JNK on pro-inflammatory mediators, proteins in the GPR109A-COX-prostaglandin pathway, microglial activation, and neuronal death. Inhibiting JNK may reverse the changes observed in the diminished flush response, which might make it a good therapeutic target.

The clinical and functional outcomes of a large naturalistic cohort of young people accessing national early psychosis services

Aims: Services for individuals with a first episode of psychosis or at ultra-high risk of psychosis have become a treatment model of choice in mental health care. The longitudinal changes in clinical and functional outcomes as a result of real-world treatment remain under-reported. Methods: We analysed data from first episode of psychosis and ultra-high risk services delivered across Australian primary youth mental health care services known as headspace between 19 June 2017 and 30 September 2019. Outcome measures were completed and entered into a minimum dataset every 90 days a participant was receiving treatment and included psychiatric symptomatology (Brief Psychiatric Rating Scale and psychological distress, K10) and psychosocial functioning (Social and Occupational Functioning Assessment Scale and My Life Tracker). Linear mixed-effects models were used to evaluate changes in outcome over time. Results: Outcome data from a total of 1252 young people were evaluated (643 first episode of psychosis, 609 ultra-high risk). Of those who entered ultra-high risk services, 11.8% transitioned to first episode of psychosis services. Overall, substantial improvement in clinical (Brief Psychiatric Rating Scale, K10) and functional (Social and Occupational Functioning Assessment Scale, My Life Tracker) outcomes were seen across groups and outcomes. Ultra-high risk patients showed a greater reduction in distress symptoms, while first episode of psychosis patients experienced a greater reduction in positive psychosis symptoms. Although clinical outcomes showed a plateau effect after approximately 3 months of care, improvement in functional outcomes (Social and Occupational Functioning Assessment Scale, My Life Tracker) continued later in treatment. Conclusion: These findings support the use of real-time, real-world and low-cost administrative data to rigorously evaluate symptomatic and functional outcomes in early psychosis treatment settings. Findings that functional outcomes improve past the remittance of clinical outcomes also support the functional recovery focus of early psychosis services and remaining high levels of distress suggest the need for ultra-high risk services to extend beyond 6 months of care.

Neurocognition and Social Cognition— Possibilities for Diagnosis and Treatment in Ultra-High Risk for Psychosis State

In recent decades, clinicians have developed the construct of ultra-high risk (UHR) for psychosis to characterize the prodromal phase of psychosis or classify people with weakly expressed psychotic symptoms. In this conceptual analysis, we have gathered up-to-date data about the clinical picture of neurocognition and social cognition in people at UHR for psychosis. We also discuss treatment options. A well-chosen therapeutic approach can help to deal with difficulties and delay or even prevent the development of full-blown psychotic disorders in the UHR group. Despite much evidence supporting the benefits of therapy, early interventions are still not as widely used as they should be. Thus, a better understanding of the UHR state is very important for all healthcare workers.

Intelligence trajectories in individuals at ultra-high risk for psychosis: An 8-year longitudinal analysis

Background: Cognitive impairment is a well-documented predictor of transition to a full-threshold psychotic disorder amongst individuals at ultra-high risk (UHR) for psychosis. However, less is known about whether change in cognitive functioning differs between those who do and do not transition to a psychotic disorder. Studies to date have not examined trajectories in intelligence constructs (e.g., acquired knowledge and fluid intelligence), which have demonstrated marked impairments in individuals with schizophrenia. This study aimed to examine intelligence trajectories using longitudinal data from three time-points, spanning an average of eight years.Methods: Participants (N=139) at UHR for psychosis completed the Wechsler Abbreviated Scale of Intelligence (WASI) at each follow-up. Linear mixed-effects models mapped changes in WASI Full-Scale IQ (FSIQ) and T-scores on Vocabulary, Similarities, Block Design, and Matrix Reasoning subtests.Results: The sample showed stable and improving trajectories for FSIQ and all subtests. There were no significant differences in trajectories between those who did and did not transition to psychosis and between individuals with good and poor functional outcomes. However, although not significant, the trajectories of the acquired knowledge subtests diverged between transitioned and non-transitioned individuals (β=−0.12, 95% CI [−0.29, 0.05] for Vocabulary and β=−0.14, 95% CI [−0.33, 0.05] for Similarities). Conclusions: There was no evidence for long-term deterioration in intelligence trajectories in this UHR sample. As the small sample of individuals who transitioned may have limited our ability to detect subtle differences, future studies with larger sample sizes are needed to explore potential differences in intelligence trajectories between UHR transition groups.

Empathy and Its Relationship With Social Functioning in Individuals at Ultra-High Risk for Psychosis

Introduction: Social functioning is often impaired in the ultra-high-risk (UHR) phase of psychosis. There is some evidence that empathy is also impaired in this phase and that these impairments may underlie difficulties in social functioning. The main aim of this study was to investigate whether cognitive and affective empathy are lower in people in the UHR phase of psychosis in comparison to healthy controls, and whether possible impairments have the same magnitude as in people with schizophrenia. A second aim was to examine whether there is a relationship between empathy and social functioning in individuals in the UHR phase.Method: Forty-three individuals at UHR for psychosis, 92 people with a schizophrenia spectrum disorder, and 49 persons without a psychiatric disorder completed the Interpersonal Reactivity Index (IRI), Questionnaire of Cognitive and Affective Empathy (QCAE), and Faux Pas as instruments to measure empathy. The Time Use survey was used to measure social functioning. MAN(C)OVA was used to analyse differences between groups on empathy and social functioning, and correlations were calculated between empathy measures and social functioning for each group.Results: The UHR group presented significantly lower levels of self-reported cognitive empathy than the healthy controls, but not compared to patients with SSD, while performance-based cognitive empathy was unimpaired in the UHR group. On the affective measures, we found that people with UHR and patients with SSD had significantly higher levels of self-reported distress in interpersonal settings compared to healthy controls. In the UHR group, perspective-taking was negatively associated with time spent on structured social activities. In the SSD group, we found that structured social activities were positively associated with perspective-taking and negatively associated with personal distress in interactions with others. Lastly, in people without mental illness, social activities were positively associated with performance-based perspective-taking.Conclusion: Impairments in subjective cognitive empathy appear to be present in the UHR phase, suggesting that difficulties in interpreting the thoughts and feelings of others precede the onset of psychotic disorders. This can inform future interventions in the UHR phase.

Daratumumab, Cyclophosphamide, Bortezomib, Lenalidomide, Dexamethasone (Dara-CVRd), V-Augmented Autologous Stem Cell Transplant (V-ASCT) and Dara-Vrd Consolidation in Ultra-High Risk (UHiR) Newly Diagnosed Myeloma (NDMM) and Primary Plasma Cell Leukemia (pPCL) Compared with Myeloma XI/XI+ Trial Treatment for Uhir MM: The UK Optimum/Muknine Trial

Background: Outcomes for patients with ultra-high risk (UHiR) newly diagnosed multiple myeloma (NDMM) and patients with primary plasma cell leukemia (pPCL) remain unsatisfactory with current standard therapies. Traditional comparative trials randomising against a standard of care control arm are thus challenging for patients with UHiR NDMM or pPCL, and novel approaches to address their high unmet need are required. OPTIMUM/MUKnine (NCT03188172) is a 'digital comparator arm' trial for UHiR NDMM and pPCL patients with protocol defined outcome comparison against fully molecularly matched UHiR patients from the near-concurrent NCRI Myeloma XI/XI+ trial, the 'MyXI prior'. We report final analysis of the primary endpoint progression free survival (PFS) at 18 months for patients treated in OPTIMUM with Dara-CVRd induction, V-augmented ASCT and Dara-VRd consolidation, compared to the MyXI prior. Methods: Between Sep 2017 and Jul 2019, 472 patients from 39 UK hospitals with suspected NDMM or pPCL were screened. 107 patients with UHiR NDMM by central trial genetic (≥2 high risk lesions: t(4;14), t(14;16), t(14;20), gain(1q), del(1p), del(17p)) or gene expression SKY92 (SkylineDx) profiling, or with pPCL (circulating plasmablasts >20%) were identified and recruited to OPTIMUM. Patients received up to 6 cycles of Dara-CVRd induction, V-ASCT, followed by Dara-VRd consolidation 1 for 6 cycles (Cons1), Dara-VR consolidation 2 for 12 cycles and monthly Dara-R maintenance until progression. This is the final analysis of the primary trial endpoint progression-free survival (PFS) at 18 months comparing OPTIMUM with the MyXI prior of patients treated with CRd or carfilzomib-CRd (KCRd) induction, ASCT and R maintenance or observation, using a Bayesian framework. Secondary endpoints include PFS, OS, safety and quality of life. Results: At median follow-up of 27.1 months (95% CI 25.1-29.3), median PFS was not reached for OPTIMUM patients. PFS was superior at the pre-specified time point of 18 months for OPTIMUM patients with an estimate of 81.7% (95% CI: 74.2-89.1) versus 65.9% (95% CI: 57.3-74.4) for the MyXI prior (Figure 1). PFS at 18 months was consistently shorter for both CRd (64.5%; 95% CI: 53.8-75.3) and KCRd (68.3%; 95% CI: 54.0-82.5) treated patients compared with OPTIMUM. There was a 99.5% chance of superior PFS outcome with OPTIMUM therapy compared to the MyXI prior within the Bayesian framework; easily surpassing the 85% pre-specified threshold of sufficient evidence of activity. The difference between trial treatments increased over time: 6 month estimates were similar across all treatment arms with OPTIMUM 95.3% (95% CI: 91.3-99.3), MyXI KCRd 95.1% (95% CI: 88.5-100.0), MyXI CRd 93.5% (95% CI: 88.0-99.0), while 12 month estimates were similar for OPTIMUM with 87.5% (95% CI: 81.2-93.9) and MyXI KCRd 87.8% (77.8-97.8), but lower in CRd 81.7% (95% CI: 73.0-90.3). The majority (94%) of patients who started OPTIMUM Cons1 completed all 6 cycles of therapy. Most frequent grade 3/4 adverse events (AEs) during Cons1 included thrombocytopenia (27.9%), neutropenia (21%) and infection (19.8%), however, grade 4 events were rare (<5%) for all categories, consistent with previously presented data on induction. We previously reported high MRD-negativity rates of 61% at day +100 post V-ASCT for OPTIMUM, with a lower rate of 40% of patients showing both complete response (CR) and MRD-neg. With further follow-up, CR rate increased to 68.2% (95% CI: 58.5-76.9) at end of Cons1, including virtually all patients with MRD-neg finding post V-ASCT. Conclusions: OPTIMUM demonstrated a clear PFS benefit at 18 months for intensified Dara combination therapy pre- and post-ASCT for UHiR NDMM and pPCL over the MyXI prior. Improvement of comparative benefit over time suggests particular efficacy of Dara-VRd in maintaining responses post ASCT, a key challenge in UHiR MM. This is, to our knowledge, the first prospective digital comparator trial for MM; central screening of an all-comer population combined with robust, detailed molecular matching maintained reliability and limited biases. These results demonstrate a novel framework for accelerated comparative evidence generation for patients with high unmet clinical need. Figure 1 Figure 1.

Circulating Plasma Cells Are the Most Powerful Prognostic Marker in Transplant Ineligible Multiple Myeloma with 2% As a New Cut-Off for Primary Plasma Cell Leukemia

Background: Tumor burden in multiple myeloma (MM) is routinely evaluated in the bone marrow, though its prognostic value is not proven. There is an increasing interest in liquid biopsies due to its minimally invasive nature and more comprehensive evaluation of tumor burden. Growing evidence supports the quantification of circulating plasma cells (cPCs) measured by multiparameter flow cytometry (MFC) as a powerful diagnostic biomarker suitable for risk stratification of newly diagnosed transplant eligible MM (Garces et al, EHA 2021). Nevertheless, there are virtually no data regarding prognostic impact of cPCs in MM patients ineligible for transplantation. Primary plasma cell leukemia (pPCL) is a rare and most aggressive monoclonal gammopathy with dismal outcomes defined by more than 20% of cPCs and/or absolute cPCs count of ≥2 x10 9/L. Recently, there have been many efforts to redefine these criteria as lower number of cPCs probably portends equally poor prognosis. Aims: To evaluate prognostic significance of cPCs in a large cohort of transplant ineligible (Tx-ineligible) newly diagnosed MM patients and to define cut-offs for risk stratification. Moreover, to establish cut-off identifying ultra high risk MM patients mimicking the prognosis of pPCL and propose new definition of pPCL. Methods: Circulating PCs were measured by 8 color flow cytometry in 402 Tx-ineligible MM patients (including n=7 pPCL) diagnosed between 2012 and 2019 at University Hospitals Brno and Ostrava, Czech Republic. Patients were treated in real-world setting and the clinical analysis was performed retrospectively based on data from the Czech Registry of Monoclonal Gammopathies. Median follow-up was 20.5 months. The intermediate cutoff was identified using ROC analysis considering overall survival (OS). Moreover, data from the large published cohort of pPCL patients treated in real-world setting were used to find a new cut-off identifying these ultra-high-risk pPCL-like patients (Jurczyszyn et al. BJH,2018). Results: Circulating PCs were detected in peripheral blood (PB) of 303/402 (75%) patients. In 303 patients with detectable cPCs the median percentage was 0.06% with range 0.0008% - 79%. The median limit of detection of MFC technique was 0.006 (sensitivity 10e-5). Patients stratification into 3 subgroups according to quantification of cPCs (low: ≤ 0.2%; intermediate: 0.2 - 2% and high: >2.0%) resulted in significantly different OS (36.5 vs. 28.1 and 13.6 months; p < 0.0001) and progression free survival (PFS) (17.9 vs. 14.7 and 3.4 months; p < 0.0001). Patients with no detected cPCs (0%) did not separate from subgroup >0% to <0.2% (p >0.05) suggesting that next-generation flow cytometry (NGF) with sensitivity 10e-6 is needed for the identification of this favorable prognostic group. In order to demonstrate that patients with more than 2% of cPCs have similarly poor outcome as pPCL patients, we compared those with 2% - 20% (n=15) vs. those with >20% (n=7) of cPCs. The outcomes were practically identical with median PFS of 3.1 vs. 4.2 months (p = 0.23) and median OS of 13.6 vs. 14.6 months (p=0.23). Next, we analyzed patient´s characteristics in association with the level of cPCs (low, intermediate and high) and we demonstrated that there was significantly higher proportion of patients with ISS III stage (38%, 52% and 82%), elevated LDH level (8%, 19% and 55%) and high risk cytogenetics (12%, 21% and 36%) hand in hand with increasing number of cPCs. CPCs were identified as the most powerful prognostic marker in univariate (HR=2.7 for OS and HR=6.3 for PFS; p=0.001) and multivariate analysis (HR=4.2 for OS and HR=5.8 for PFS; p<0.001), including ISS, LDH and FISH cytogenetics. Conclusion: The quantification of cPCs in PB of newly diagnosed MM is the most powerful prognostic factor as we demonstrated on a large cohort of transplant ineligible patients. We defined 2% of cPCs as a new cut-off for ultra high risk myeloma resembling behavior of primary PCL. We propose this 2% cut-off for redefinition of pPCL criteria that warrants further investigation in prospective setting. To identify subgroup with especially favorable outcome with no detectable cPCs, NGF with high sensitivity of 10e-6 is needed. Quantification of cPCs by MFC is easy, fast, affordable and worldwide available procedure providing highly relevant prognostic information that might be implemented into routine clinical practice.
