RESUMEN
OBJECTIVE: To describe the characteristics of individuals with early sustained recovery following first episode psychosis. METHODS: Individuals with a first episode psychosis were followed-up for ten years. Comparisons were made between those with Early Sustained Recovery and those with Other Course types. RESULTS: Of 345 individuals, n=43 (12.5%) had Early Sustained Recovery. They were more likely than those with Other Course types to be female (OR=2.45; 95% CI: 1.25-4.81); employed (OR=2.39; 95% CI: 1.22-4.69); in a relationship (OR=2.68; 95% CI: 1.35-5.32); have a short DUP (OR=2.86; 95% CI: 1.37-5.88); and have a diagnosis other than schizophrenia, particularly mania (OR=6.39; 95% CI: 2.52-16.18) or brief psychosis (OR=3.64; 95% CI: 1.10-12.10). CONCLUSIONS: Sustained recovery from first episode psychosis occurs in a minority.

BACKGROUND: We examined longitudinally the course and predictors of treatment resistance in a large cohort of first-episode psychosis (FEP) patients from initiation of antipsychotic treatment. We hypothesized that antipsychotic treatment resistance is: (a) present at illness onset; and (b) differentially associated with clinical and demographic factors. METHOD: The study sample comprised 323 FEP patients who were studied at first contact and at 10-year follow-up. We collated clinical information on severity of symptoms, antipsychotic medication and treatment adherence during the follow-up period to determine the presence, course and predictors of treatment resistance. RESULTS: From the 23% of the patients, who were treatment resistant, 84% were treatment resistant from illness onset. Multivariable regression analysis revealed that diagnosis of schizophrenia, negative symptoms, younger age at onset, and longer duration of untreated psychosis predicted treatment resistance from illness onset. CONCLUSIONS: The striking majority of treatment-resistant patients do not respond to first-line antipsychotic treatment even at time of FEP. Clinicians must be alert to this subgroup of patients and consider clozapine treatment as early as possible during the first presentation of psychosis.
