Background. Schizophrenia is frequently complicated by the occurrence of depressive symptoms, anhedonia, obsessions and compulsions, suicidal ideation, and substance abuse, that causes exacerbations and remissions and, in several cases, sustained morbidity and disability. Aim. The present study aimed to evaluate the effect of paliperidone palmitate once-monthly long-acting injection (PP-LAI) mainly on “non-core” symptoms in persons with recent diagnosis schizophrenia, during a follow-up period of almost 12 months (T1) in the context of the “real world” everyday clinical practice. Results. Concerning core symptoms of schizophrenia, PP-LAI was effective in reducing all symptoms at T1 as measured by Positive and Negative Syndrome Scale (PANSS), including depressive symptoms, and increased the functioning. Moreover, concerning the non-core symptoms of schizophrenia, PP-LAI treatment was effective in reducing scores of anhedonia, suicidal ideation and obsessive-compulsive symptoms at T1. However, the levels of alexithymia remained relatively stable, even if reduced. Discussion. The present retrospective, multicenter, non-sponsored, collaborative study showed that early PP-LAI treatment was effective in improving almost all the core dimensions and “non-core” symptoms of schizophrenia, and this may have positive repercussions on both functioning and quality of life. Conclusions. PP-LAI treatment should be offered earlier as possible and was effective on “non-core” symptoms of schizophrenia at follow-up, but had a little effect on alexithymia. However, study' limitations must be considered and future researches are needed to confirm these interesting findings.

Abstract

Background. Schizophrenia is frequently complicated by the occurrence of depressive symptoms, anhedonia, obsessions and compulsions, suicidal ideation, and substance abuse, that causes exacerbations and remissions and, in several cases, sustained morbidity and disability. Aim. The present study aimed to evaluate the effect of paliperidone palmitate once-monthly long-acting injection (PP-LAI) mainly on “non-core” symptoms in persons with recent diagnosis schizophrenia, during a follow-up period of almost 12 months (T1) in the context of the “real world” everyday clinical practice. Results. Concerning core symptoms of schizophrenia, PP-LAI was effective in reducing all symptoms at T1 as measured by Positive and Negative Syndrome Scale (PANSS), including depressive symptoms, and increased the functioning. Moreover, concerning the non-core symptoms of schizophrenia, PP-LAI treatment was effective in reducing scores of anhedonia, suicidal ideation and obsessive-compulsive symptoms at T1. However, the levels of alexithymia remained relatively stable, even if reduced. Discussion. The present retrospective, multicenter, non-sponsored, collaborative study showed that early PP-LAI treatment was effective in improving almost all the core dimensions and “non-core” symptoms of schizophrenia, and this may have positive repercussions on both functioning and quality of life. Conclusions. PP-LAI treatment should be offered earlier as possible and was effective on “non-core” symptoms of schizophrenia at follow-up, but had a little effect on alexithymia. However, study' limitations must be considered and future researches are needed to confirm these interesting findings.
