Schizophrenia Spectrum Disorders in Relation to the Totality of Psychosis: From First Episode to Long-Term Outcome

BackgroundSeveral national guidelines recommend continuous use of antipsychotic medication after a psychotic episode in order to minimize the risk of relapse. However some studies have identified a subgroup of patients who can obtain remission of psychotic symptoms while not being on antipsychotic medication for a long period of time. This study investigated the long-term outcome and characteristics of patients in remission of psychotic symptoms with no use of antipsychotic medication at the 10-year follow-up.MethodsThe study was a cohort study including 496 patients diagnosed with schizophrenia spectrum disorders (ICD 10: F20 and F22-29). Patients were included in the Danish OPUS Trial and followed up 10 years after inclusion, where patient data was collected on socio-demographic factors, psychopathology, level of functioning and medication.FindingsAmong the patients, 30% had remission of psychotic symptoms at the time of the 10-year follow up with no current use of antipsychotic medication. This favorable outcome was associated with female gender, high GAF-F score, participation in the labor market and absence of substance abuse.InterpretationResults from several RCTs advise against discontinuation of antipsychotic medication, but our results from the 10-year follow-up indicate that a subgroup do obtain long-term remission while not being on antipsychotic medication. Hence, guidelines on antipsychotic medication do not pay sufficient attention to patients who discontinue antipsychotic medication and are still able to obtain remission of psychotic symptoms.Disclosure of interestThe authors have not supplied their declaration of competing interest.

AbstractBackgroundAlthough relapse in psychosis is common, a small proportion of patients will not relapse in the long term. We examined the proportion and predictors of patients who never relapsed in the 10 years following complete resolution of positive symptoms from their first psychotic episode.MethodPatients who previously enrolled in a 12-month randomized controlled trial on medication discontinuation and relapse following first-episode psychosis (FEP) were followed up after 10 years. Relapse of positive symptoms was operationalized as a change from a Clinical Global Impression scale positive score of <3 for at least 3 consecutive months to a score of ⩾3 (mild or more severe). Baseline predictors included basic demographics, premorbid functioning, symptoms, functioning, and neurocognitive functioning.ResultsOut of 178 first-episode patients, 37 (21%) never relapsed during the 10-year period. Univariate predictors (p ⩽ 0.1) of patients who never relapsed included a duration of untreated psychosis (DUP) ⩽30 days, diagnosed with non-schizophrenia spectrum disorders, having less severe negative symptoms, and performing better in logical memory immediate recall and verbal fluency tests. A multivariate logistic regression analysis further suggested that the absence of any relapsing episodes was significantly related to better short-term verbal memory, shorter DUP, and non-schizophrenia spectrum disorders.ConclusionsTreatment delay and neurocognitive function are potentially modifiable predictors of good long-term prognosis in FEP. These predictors are informative as they can be incorporated into an optimum risk prediction model in the future, which would help with clinical decision making regarding maintenance treatment in FEP.

Long Term Prognosis

Background: The outcome of schizophrenia and related psychoses is generally modest, and patients display high rates of disability. Aims: The aim of the review is to present an up-to-date account of the research on the very long-term outcome of psychotic disorders. Method: We conducted a search in the PubMed and Scopus databases for articles published since the publication of the very long-term data of the World Health Organization’s International Study of Schizophrenia (the ISoS study), over the last 18 years (from 2002 to 2019). Studies were included if they reported on at least 15-year outcome and if they had used valid and reliable tools for the estimation of the patients’ outcome in terms of symptomatology and functioning. Results: A total of 16 studies were included in this review, involving 1,391 patients with schizophrenia and related psychoses. Most were single-center studies, with moderate size samples of patients, and 11 were prospective studies. Very long-term outcome of psychotic disorders varies considerably among studies. Good outcome ranges from 8% to 73.8%, and it appears to be better in developing countries, whereas differences are less apparent among Western countries (8%–40.3%). Studies in different settings have used different methods involving a variety of samples of patients to estimate their outcome, whereas definitions of good and poor outcome also varied among studies. Longer duration of untreated psychosis was associated with worse outcome in some studies. Schizophrenia was found to have poorer long-term prognosis compared to other schizophrenia spectrum disorders. A large proportion of patients, ranging from 19% to 48.2%, were not on medication. Conclusion: Recent evidence on the very long-term outcome of psychotic disorders is in line with previous reports and suggests that prognosis remains rather modest. There are several limitations of current research regarding outcome definitions and study design that should be addressed by future research.
