Prevalence and identification of neuropsychiatric symptoms in systemic autoimmune rheumatic diseases: an international mixed methods study

Barriers and Facilitators to Psychological Safety During Medical Procedures Among Individuals Diagnosed with Chronic Illness in Childhood

Background: This study explores barriers and facilitators to psychological safety during medical procedures among individuals diagnosed with chronic illnesses in childhood. Psychological safety in healthcare, detected via neuroception and the autonomic nervous system's responses to perceived safety or threat, is essential for the well-being and mental health of chronically ill patients, especially those with early diagnoses. Methods: Using Polyvagal Theory as a framework, semi-structured interviews were conducted with six participants (aged 20-64) who experienced chronic disease from a young age. The Neuroception of Psychological Safety Scale (NPSS) guided thematic exploration to understand participants' experiences. Thematic analysis identified key themes that reflect contributors and detractors to psychological safety during medical care. Results: Four primary themes were developed: (1) knowledge empowerment through information and facilitated inquiry, (2) holistic acknowledgment of psychological and social impacts, (3) the role of parental involvement in healthcare interactions, and (4) the need for an individualised, patient-centred approach. Participants expressed a need for psychological support integrated with their medical treatment and the importance of autonomy and clear communication. Conclusions: Psychological safety is central to medical experiences for chronically ill individuals and requires a patient-centred, psychologically informed approach. Emphasising tailored support, family involvement, and comprehensive mental health consideration can foster more effective care and enhance patients' long-term well-being.

Three cases with chronic obsessive compulsive disorder report gains in wellbeing and function following rituximab treatment

Immunological aetiology is supported for a subgroup with obsessive compulsive disorder (OCD) and conceptualized as autoimmune OCD. The longitudinal clinical course is detailed for three severely ill cases with OCD and indications of immunological involvement with off-label rituximab treatment every six months. All cases showed clear and sustained gains regarding symptom burden and function for over 2.5 years. Brief Psychiatric Rating Scale and Yale-Brown Obsessive-Compulsive Inventory Scale scores decreased 67-100% and 44-92%, respectively. These complex cases, prior to rituximab, had very low functioning and disease duration has been eight, nine and 16 years respectively. All three patients had been unsuccessfully treated with at least two antidepressants or anxiolytics, one neuroleptic and cognitive behavioural therapy. Clinical phenotypes and findings were suggestive of possible autoimmune OCD. Indirect immunohistochemistry detected cerebral spinal fluid (CSF) antibodies in all three cases including a novel anti-neuronal staining pattern against mouse thalamic cells. Exploratory analyses of CSF markers and proteomics identified elevated levels of sCD27 and markers indicative of complement pathway activation when compared to CSF from healthy controls. Multidisciplinary collaboration, advanced clinical investigations and rituximab treatment are feasible in a psychiatric setting. The case histories provide a proof of principle for the newly proposed criteria for autoimmune OCD. The findings suggest that clinical red flags and biological measures may predict rituximab response in chronic treatment-resistant OCD. The report provides orientation that may inform the hypotheses and design of future treatment trials.

Association between a history of mental illness and the risk of systemic autoimmune rheumatic diseases: a nationwide, population-based case-control study

OBJECTIVE

Patients with systemic autoimmune rheumatic diseases (SARD) are at risk of mental illness, but whether mental illnesses are risk factors for SARD, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), systemic sclerosis (SSc), dermatomyositis (DM)/polymyositis (PM), are still unknown. Therefore, we aim to address the association between a history of mental illnesses and the risk of SARD using a population-based database.

METHODS

We used the 2000-2020 Taiwanese National Health Insurance Research Database in this case-control study. Multivariable logistic regression was conducted to estimate the adjusted odds ratios (aORs) with 95% confidence interval (CIs). Sensitivity analyses were conducted using distinct definitions of mental illnesses and wash-out periods.

RESULTS

A total of 77,848 SARD cases and 313,392 age- and sex-matched non-SARD controls (1:4) were included for analyses. Patients with SARD were more likely to have history of mental illness (39.8% vs. 27.0%, p < 0.001). After adjusting for potential confounders, we found significant associations of between a history of mental illnesses with SARD (aOR, 1.65, 95%CI, 1.62-1.68), RA (aOR, 1.28, 95% CI, 1.24-1.32), SLE (aOR, 1.62, 95% CI, 1.54-1.71), SS (aOR, 2.35, 95% CI, 2.28-2.42), SSc (aOR, 1.40, 95% CI, 1.24-1.58), and DM/PM (aOR, 1.18, 95% CI, 1.05-1.32). The results remained robust after using various definitions of mental illnesses and wash-out periods.

CONCLUSION

We found that a history of mental illnesses was significantly associated with incident SARD, and the strength of association tended to be strong in patients with SS, followed by SLE. More studies are warranted to clarify the underlying mechanism. Key Points • Patients with systemic autoimmune rheumatic diseases (SARD) are at risk of mental illness, but whether mental illnesses are risk factors for SARD are still unknown. • We used a population-based database to demonstrate that mental illness was associated with the risk of SARD, particularly Sjögren's syndrome and systemic lupus erythematosus. • These findings underscore the importance of integrated care approaches, including surveys for autoimmune diseases, among patients with mental illness.

British Society for Rheumatology guideline on management of adult and juvenile onset Sjögren disease

Sjögren disease (SD) is a chronic, autoimmune disease of unknown aetiology with significant impact on quality of life. Although dryness (sicca) of the eyes and mouth are the classically described features, dryness of other mucosal surfaces and systemic manifestations are common. The key management aim should be to empower the individual to manage their condition-conserving, replacing and stimulating secretions; and preventing damage and suppressing systemic disease activity. This guideline builds on and widens the recommendations developed for the first guideline published in 2017. We have included advice on the management of children and adolescents where appropriate to provide a comprehensive guideline for UK-based rheumatology teams.

Elucidating the bidirectional association between autoimmune diseases and depression: a systematic review and meta-analysis

QUESTION

Collective evidence for the bidirectional association between depression and autoimmune diseases (ADs) is scarce, especially for subgroups of patients with specific ADs. We conducted a meta-analysis to determine the incidence rates and relative risks (RRs) of depression among patients with ADs, and vice versa.

STUDY SELECTION AND ANALYSIS

PubMed, Embase, Web of Science, Ovid, PsycNet and Cochrane were searched up to 10 September 2024. Cohort studies evaluating longitudinal risks between ADs and depression were included. Incidence rates and RRs of depression among patients with ADs and vice versa were pooled.

FINDINGS

The analysis included 47 studies, involving over 40.77 million participants. The pooled incidence rate of depression among patients with ADs was 6.71% (95% CI 5.10% to 8.77%), with an RR of 1.85 (95% CI 1.57 to 2.19), higher in patients aged over 45 (2.30; 95% CI 1.62 to 3.26) and females (1.88; 95% CI 1.61 to 2.20). Conversely, the pooled incidence rate of ADs among depression was 0.54% (95% CI 0.24% to 1.19%), with an RR of 1.84 (95% CI 1.10 to 3.09). The incidence rate and RRs also varied across subgroups with the highest incidence rate in the musculoskeletal system and connective tissue (1.36; 95% CI 0.50 to 3.63) and RR in the genitourinary system (2.23; 95% CI 1.98 to 2.51).

CONCLUSIONS

This study identified a bidirectional association between depression and ADs, with higher RRs among patients aged over 45 and females. Especially higher risks were also found for specific types of ADs including endocrine, nutritional, and metabolic diseases, genitourinary system, and skin and subcutaneous tissue.

Neurological involvement in patients with systemic autoimmune rheumatic diseases: a descriptive study in an Egyptian cohort

Background

Neurologic manifestations in the systemic autoimmune rheumatic diseases (SARDs) are protean. They add to the disease burden and could contribute to mortality. Increasing awareness about the neuro-rheumatologic syndromes might help with early diagnosis and effective therapy. Our aim is to survey the clinical and imaging patterns of neurological involvement in Egyptian patients with SARDs.

Results

Neurological involvement is common in Behçet’s disease (BD) (12.7%) and systemic lupus erythematosus (SLE) (6.4%) patients compared with other SARDs. Compared with SLE, neurological involvement in BD tends to develop at an older age (31 ± 7.1 versus 28.3 ± 9.6 years = 0.022) with a greater progression risk (13.8% versus 2.6%, P = 0.003). A higher proportion of SLE patients had abnormal neuroimaging without neurological symptoms (15.7% versus 4.3%, P = 0.026, OR = 4.9, 95%CI 1.1–22.4). SLE patients had a higher frequency of seizures (31.3% versus 6.4%, P < 0.001, OR = 6.7, 95%CI 2.7–16.7) and benign intracranial hypertension (9.6% versus 1.1%, P = 0.009, OR = 9.8, 95%CI 1.2–77.7) but a lower prevalence of quadriplegia due to brain insult (1.7% versus 3.2%, P = 0.045, OR = 0.2, 95%CI 0.04–0.9), dural sinus thrombosis (13% versus 33%, P = 0.001, OR = 0.3, 95%CI 0.2–0.6), brainstem syndrome (0.9% versus 6.4%, P = 0.047, OR = 0.1, 95%CI 0–1.1) and cranial neuropathies (9.6% versus 31.9%, P < 0.001, OR = 0.2, 95%CI 0.1–0.5). Concerning neuroimaging, brain atrophic changes were more common (27.4% versus 9.5%, P = 0.002, OR = 3.6, 95%CI 1.6–8.3) while thrombosis was less prevalent (36.3% versus 53.6%, P = 0.016, OR 0.5, 95%CI = 0.3–0.9) in lupus patients. The cerebral cortex was more commonly affected (20.4 versus 4.8%, P = 0.002, OR = 5.1, 95%CI 1.7–15.4) while dural sinuses (14.2% versus 40.5%, P < 0.001, OR = 0.2, 95%CI 0.1–0.5), basal ganglia (1.8% versus 10.7%, P = 0.010, OR = 0.2, 95%CI 0–0.7), diencephalon (0% versus 13.1%, P < 0.001) and brainstem (1.8% versus 22.6%, P < 0.001, OR = 0.1, 95%CI 0–0.3) were less frequently involved in SLE patients. Concerning other SARDs, cranial neuropathies were the most common neurological presentations. Abnormalities in neuroimaging did not correlate with the patients’ clinical presentations.

Conclusions

Neurological presentations associated with SARDs are protean. Neuroimaging abnormalities should be interpreted within the context of the clinical picture and the results of other investigations.

Health seeking behaviour and diagnostic delays in SLE: A multi-ethnic Malaysian cohort study

INTRODUCTION

Heterogeneity of the clinical manifestations of systemic lupus erythematosus (SLE) may lead to diagnostic delays. This study is aimed at determining the health-seeking behaviour patterns and factors associated with diagnostic delays in a multi-ethnic SLE cohort in Malaysia.

METHODOLOGY

This was a cross-sectional study involving SLE patients who visited our institute between January 2020 and June 2021. A review of the medical records and face-to-face interviews were conducted to obtain sociodemographics, SLE disease characteristics and the intervals from the first symptoms to the diagnosis. Health-seeking behaviours were assessed by asking about the patients' first action during the initial symptoms and were divided into: (i) seeking professional health personnel; (ii) self-treatment; and (iii) the use of the internet as a primary source of information. Diagnostic delays were defined as the interval between initial symptoms and SLE diagnosis of more than 6 months. Low-level disease activity state (LLDAS) at 12 months was assessed from the medical records. Univariate and multivariate logistic regression analysis was subsequently conducted to determine factors associated with diagnostic delays.

RESULTS

Among the 154 patients included in the study, 24% (n = 37) had delayed diagnosis. The delay was significantly higher among the Indian versus Malay versus Chinese (42.9% vs 28% vs 10.8%, p = 0.037). Patients with rash tend to have delayed diagnosis (37.8% vs 22.2%, p = 0.08) while fewer patients with frothy urine had delayed diagnosis (8.1% vs 21.4%, p = 0.09). No significant association was found between health-seeking behaviours and diagnostic delays. The rate of LLDAS at 12 months was significantly lower among patients with delayed diagnosis (43.2% vs 70.0%, p = 0.006). Chinese ethnicity remained the only significant factor associated with lesser diagnostic delays in the multivariate analysis, with OR 0.30 (CI 0.09-0.93), p = 0.037.

CONCLUSION

There were ethnic disparities in the early diagnosis of SLE in Malaysia, with Indian patients having a longer interval between the first symptom and diagnosis while the Chinese were associated with lower diagnostic delays. Early diagnosis predicted early attainment of LLDAS, suggesting that prompt recognition of the initial SLE symptoms is important.

Attribution of neuropsychiatric symptoms and prioritization of evidence in the diagnosis of neuropsychiatric lupus: mixed methods analysis of patient and clinician perspectives from the international INSPIRE study

OBJECTIVE

Neuropsychiatric lupus (NPSLE) is challenging to diagnose. Many neuropsychiatric symptoms, such as headache and hallucinations, cannot be verified by tests or clinician assessment. We investigated prioritizations of methods for diagnosing NPSLE and attributional views.

METHODS

Thematic and comparative analyses were used to investigate how clinicians prioritize sources of evidence from a 13-item list, and explore discordances in clinician (surveys n = 400, interviews n = 50) and patient (surveys n = 676, interviews n = 27) perspectives on attribution.

RESULTS

We identified high levels of variability and uncertainty in clinicians' assessments of neuropsychiatric symptoms in SLE patients. In attributional decisions, clinicians ranked clinicians' assessments above diagnostic tests (many of which they reported were often unenlightening in NPSLE). Clinicians ranked patient opinion of disease activity last, and 46% of patients reported never/rarely having been asked if their SLE was flaring, despite experienced patients often having 'attributional insight'. SLE patients estimated higher attributability of neuropsychiatric symptoms to the direct effects of SLE on the nervous system than clinicians (P < 0.001 for all symptoms excluding mania), and 24% reported that their self-assessment of disease activity was never/rarely concordant with their clinicians. Reports of misattributions were common, particularly of non-verifiable diffuse symptoms. Terminology differed between clinicians and influenced attribution estimates.

CONCLUSION

NPSLE diagnostic tests and clinician assessments have numerous limitations, particularly in detecting diffuse neuropsychiatric symptoms that can be directly attributable and benefit from immunosuppression. Our findings suggest that incorporating patient attributional insights-although also subject to limitations-may improve attribution decision-making. Consensus regarding terminology and interpretations of 'direct attributability' is required.

Associations Between Neuropsychiatric Symptoms and Inflammation in Neurodegenerative Dementia: A Systematic Review

Background

Neuropsychiatric symptoms are common in dementia and linked to adverse outcomes. Inflammation is increasingly recognized as playing a role as a driver of early disease progression in Alzheimer's disease (AD) and related dementias. Inflammation has also been linked to primary psychiatric disorders, however its association with neuropsychiatric symptoms in neurodegenerative dementias remains uncertain.

Methods

We conducted a systematic literature review investigating associations between inflammation and neuropsychiatric symptoms in neurodegenerative dementias, including AD, Lewy body, Frontotemporal, Parkinson's (PD) and Huntington's disease dementias.

Results

Ninety-nine studies met our inclusion criteria, and the majority (n = 59) investigated AD and/or mild cognitive impairment (MCI). Thirty-five studies included PD, and only 6 investigated non-AD dementias. Inflammation was measured in blood, CSF, by genotype, brain tissue and PET imaging. Overall, studies exhibited considerable heterogeneity and evidence for specific inflammatory markers was inconsistent, with lack of replication and few longitudinal studies with repeat biomarkers. Depression was the most frequently investigated symptom. In AD, some studies reported increases in peripheral IL-6, TNF-a associated with depressive symptoms. Preliminary investigations using PET measures of microglial activation found an association with agitation. In PD, studies reported positive associations between TNF-a, IL-6, CRP, MCP-1, IL-10 and depression.

Conclusion

Central and peripheral inflammation may play a role in neuropsychiatric symptoms in neurodegenerative dementias; however, the evidence is inconsistent. There is a need for multi-site longitudinal studies with detailed assessments of neuropsychiatric symptoms combined with replicable peripheral and central markers of inflammation.

An exploratory study of the damage markers NfL, GFAP, and t-Tau, in cerebrospinal fluid and other findings from a patient cohort enriched for suspected autoimmune psychiatric disease

There is growing evidence suggesting that immunological mechanisms play a significant role in the development of psychiatric symptoms in certain patient subgroups. However, the relationship between clinical red flags for suspected autoimmune psychiatric disease and signs of central nervous system (CNS) pathology (e.g., routine cerebrospinal fluid (CSF) alterations, CNS damage markers, neurophysiological or neuroimaging findings) has received limited attention. Here, we aimed to describe the prevalence and distribution of potential CNS pathologies in psychiatric patients in relation to clinical red flags for autoimmune psychiatric disease and psychiatric symptoms. CSF routine findings and CNS damage markers; neurofilament light chain protein (NfL), glial fibrillary acidic protein (GFAP) and total Tau (t-Tau), in CSF from 127 patients with psychiatric disease preselected for suspected immunological involvement were related to recently proposed clinical red flags, psychiatric features, and MRI and EEG findings. Twenty-one percent had abnormal routine CSF findings and 27% had elevated levels of CNS damage markers. Six percent had anti-neuronal antibodies in serum and 2% had these antibodies in the CSF. Sixty-six percent of patients examined with MRI (n = 88) had alterations, mostly atrophy or nonspecific white matter lesions. Twenty-seven percent of patients with EEG recordings (n = 70) had abnormal findings. Elevated NfL levels were associated with comorbid autoimmunity and affective dysregulation symptoms. Elevated t-Tau was associated with catatonia and higher ratings of agitation/hyperactivity. Elevated GFAP was associated with acute onset, atypical presentation, infectious prodrome, tics, depressive/anxiety symptom ratings and overall greater psychiatric symptom burden. In conclusion, preselection based on suspected autoimmune psychiatric disease identifies a population with a high prevalence of CSF alterations suggesting CNS pathology. Future studies should examine the value of these markers in predicting treatment responses.

Barriers, Facilitators, and Preferences for Mental Health Services Among Patients With Systemic Lupus Erythematosus: A Qualitative Study

OBJECTIVE

Although patients with systemic lupus erythematosus (SLE) experience high levels of depression and anxiety disorders, evidence concerning patient perceptions of facilitators and barriers to effective uptake of mental health services (eg, referral to therapists and psychiatrists, psychoeducational interventions, or support groups) is limited.

METHODS

We conducted semistructured qualitative interviews with 15 adults with SLE to explore patient experiences and perceptions of mental health services to identify facilitators and barriers to accessing mental health care among patients with SLE. Qualitative interviews were conducted via telephone and audio recorded for transcription and directed content analysis using NVivo software by two coders.

RESULTS

The median age of the 15 participants was 48 years, 87% were female, 33% identified as Black or African American, and 33% identified as Hispanic or Latino. Qualitative themes were organized into three domains: barriers, facilitators, and preferences for mental health services. Barriers to the use of mental health services include mental health stigma, sociodemographic factors, lack of autonomy, and time commitment. Facilitators to the use of mental health services included strong relationships with their rheumatologists and mental health care clinician experience with patients with SLE. Preferences for mental health services included education-based formats, mental health providers who work with patients with SLE, peer group formats, demographically and disease-matched psychological resources, and an emphasis on non-disease-related activities.

CONCLUSION

In the setting of persistent unmet psychosocial needs of patients living with SLE, data from this qualitative study will inform the development and refinement of mental health interventions that bolster psychological wellbeing in the SLE population.

Neuropsychiatric prodromes and symptom timings in relation to disease onset and/or flares in SLE: results from the mixed methods international INSPIRE study

Background

Neuropsychiatric symptoms in SLE and other systemic autoimmune rheumatic diseases (SARDs) are challenging to diagnose, attribute and manage. We investigated the timings of onset of a broad range of neuropsychiatric (NP) symptoms in relation to timing of SLE onset. In addition, we explored whether NP symptoms may be a prodrome to SARD onset and to subsequent flares.

Methods

We collected patient reports of the timing of their first episode of 29 NP symptoms relative to SLE non-NP symptom onset. Surveys (n = 676 SLE patients and n = 400 clinicians) and interviews (n = 50 clinicians; and n = 69 SARD patients, including 27 SLE patients) were completed from 2022 to 2023, and analysed using mixed methods.

Findings

The majority of NP symptoms did not first present around the time of SLE onset, contrary to the prevailing view among many rheumatology participants and in the literature. For example, among patients who experienced hallucinations, 54% reported first presentation >1 year after disease onset. Patient interviews also revealed that a range of NP symptoms may be a prodrome to SLE/SARDs onset and later flares, including symptoms not represented in existing classification criteria. Evidence of a possible prodromal syndrome was elicited from those patients who experienced hallucinations. Of these, 61% (SLE) and 34% (other SARDs) reported increasingly disrupted dreaming sleep (usually nightmares) prior to their hallucinations. In-depth interviews revealed that progression of symptoms in flares showed a high degree of inter-patient variation, whilst symptom progression was often similar in individual patient's recurrent flares.

Interpretation

Neuropsychiatric symptoms can first present at any stage in the SLE disease course. Attributional decisions should evaluate timings of NP symptoms in relation to timing of SLE/SARD symptom onset rather than time of diagnosis due to frequent diagnostic delays. Greater recognition of prodromal/early NP symptoms indicating impending SLE flares (and potentially other SARD flares) could enable quicker flare identification and treatment.

Understanding the psychosocial determinants of effective disease management in rheumatoid arthritis to prevent persistently active disease: a qualitative study

BACKGROUND

According to epidemiological studies, psychosocial factors are known to be associated with disease activity, physical activity, pain, functioning, treatment help-seeking, treatment waiting times and mortality in people with rheumatoid arthritis (RA). Limited qualitative inquiry into the psychosocial factors that add to RA disease burden and potential synergistic interactions with biological parameters makes it difficult to understand patients' perspectives from the existing literature.

AIM

This study aimed to gather in-depth patient perspectives on psychosocial determinants that drive persistently active disease in RA, to help guide optimal patient care.

METHODS

Patient research partners collaborated on the research design and materials. Semistructured interviews and focus groups were conducted online (in 2021) with patients purposively sampled from diverse ethnicities, primary languages, employment status and occupations. Data were analysed using inductive thematic analysis.

RESULTS

45 patients participated across 28 semistructured interviews and three focus groups. Six main themes on psychosocial determinants that may impact RA management were identified: (1) healthcare systems experiences, (2) patient education and health literacy, (3) employment and working conditions, (4) social and familial support, (5) socioeconomic (dis)advantages, and (6) life experiences and well-being practices.

CONCLUSION

This study emphasises the importance of clinicians working closely with patients and taking a holistic approach to care that incorporates psychosocial factors into assessments, treatment plans and resources. There is an unmet need to understand the relationships between interconnected biopsychosocial factors, and how these may impact on RA management.
