Inflammatory markers of symptomatic remission at 6 months in patients with first-episode schizophrenia

Neuroinflammation contributes to the pathophysiology of various mental illnesses including schizophrenia. We investigated peripheral inflammatory cytokines as a biomarker for predicting symptomatic remission in patients with first-episode schizophrenia. The study included 224 patients aged 15-60 years who fulfilled the criteria for schizophrenia spectrum disorder with a treatment duration ≤6 months. Serum levels of tumor necrosis factor (TNF) -α, interferon-γ, interleukin (IL)-1α, IL-1β, IL-6, IL-8, IL-10, and IL-12 were measured. Psychotic symptoms, depressive symptoms, and general functioning were assessed using the Positive and Negative Syndrome Scale, Beck Depression Inventory (BDI), Calgary Depression Scale for Schizophrenia, and Personal and Social Performance scale, respectively. Duration of untreated psychosis (DUP) was also recorded. We investigated the factors associated with remission for each sex in logistic regression analysis. In total, 174 patients achieved remission at the 6-month follow-up (females, 83.5%; males, 70.9%). Remission was associated with older age and lower BDI scores in male patients and with lower TNF-α levels and shorter DUP in female patients. Our findings suggest that peripheral inflammatory cytokines may impede early symptomatic remission in female patients with schizophrenia. In addition, depressive symptoms in males and long DUP in females may be poor prognostic factors for early remission in patients with first-episode psychosis.

Understanding components and predictors of delay of first treatment for mental health problems: A hospital-based study in China

BACKGROUND

Understanding components and predictors of delay of first treatment for mental health problems are crucial to inform interventions for earlier treatment. However, Chinese-context knowledge of this theme is still limited.

METHODS

We conducted an inpatient survey among 206 patients with various mental disorders in China. Delay of first utilization of mental healthcare (Delay-Total) and its two components of help-seeking delay (Delay-H) and referral delay (Delay-R) were assessed in terms of occurrence and duration. Binary logistic regression was performed to test predictors of Delay-Total, Delay-H and Delay-R, and multiple linear regression was used to test predictors of delay durations.

RESULTS

Overall, 66.0% patients experienced Delay-Total, with a duration range of 0 to 353 months; 49.5% patients had Delay-H (duration range = 0-207 months) and 29.6% with Delay-R (duration range = 0-323 months). Multivariate logistic regression analysis found that the diagnosis of severe mental disorders was a consistent predictor for a reduced chance of Delay-Total, Delay-H and Delay-R. Multiple linear regression analysis demonstrated that younger age of disorder onset and disorder onset before 2016 were significantly associated with longer delay.

CONCLUSIONS

Delay of first treatment for mental health problems is still common in China. However, the development of mental health policy and services promotes shorter treatment delay. The diagnosis of common mental disorders and younger age of onset are risk factors of the occurrence and duration of delay, respectively. Thus, education of the public and non-mental-healthcare professionals are needed for better disorder recognition and more efforts should be inputted to support youngsters' utilization of mental healthcare.

Comparing treatment delays and pathways to early intervention services for psychosis in urban settings in India and Canada

INTRODUCTION

Although extensively studied in high-income countries (HICs) and less so in low- and middle-income countries (LMICs), pathways to care and treatment delays in early psychosis have not been compared across contexts. We compared pathways to early intervention for psychosis in an HIC (Montreal, Canada) and an LMIC (Chennai, India). We hypothesised that the duration of untreated psychosis (DUP) would be longer in Chennai.

METHODS

The number of contacts preceding early intervention, referral sources, first contacts, and DUP and its referral and help-seeking components of first-episode psychosis patients at both sites were similarly measured and compared using chi-square analyses and t tests/one-way ANOVAs.

RESULTS

Overall and help-seeking DUPs of Chennai (N = 168) and Montreal (N = 165) participants were not significantly different. However, Chennai patients had shorter referral DUPs [mean = 12.0 ± 34.1 weeks vs. Montreal mean = 13.2 ± 28.7 weeks; t(302.57) = 4.40; p < 0.001] as the early intervention service was the first contact for 44% of them (vs. 5% in Montreal). Faith healers comprised 25% of first contacts in Chennai. Those seeing faith healers had significantly shorter help-seeking but longer referral DUPs. As predicted, most (93%) Montreal referrals came from medical sources. Those seeing psychologists/counsellors/social workers as their first contact had longer DUPs.

CONCLUSION

Differences in cultural views about mental illnesses and organizational structures shape pathways to care and their associations with treatment delays across contexts. Both formal and informal sources need to be targeted to reduce delays. Early intervention services being the first portal where help is sought can reduce DUP especially if accessed early on in the illness course.
