In schizophrenia patients, the level of T-lymphocytes with cytogenetic aberrations is elevated, and the ability of these cells for PGA-blast-transformation and the interferon synthesis is reduced. The elevation of the lymphocytes ability for blast-transformation in the presence of the native preparation of DNA and for lysis of the erythrocytes proper is marked in these patients. The observed changes were especially marked in schizophrenia with an interrupted course.

This investigation examined self-reported psychopathology in a school-based sample of 456 suicidal and nonsuicidal adolescents. The sample consisted of four groups: three at-risk for suicidal behavior based on current suicidal ideation as assessed by the Suicidal Ideation Questionnaire (SIQ; Reynolds, 1988), past suicide attempts, or both; and one nonsuicidal comparison group. Psychopathology was examined using ten scales from the Adolescent Psychopathology Scale (APS; Reynolds, 1998a) including: Major Depression, Conduct Disorder, Substance Abuse, Schizophrenia, Adjustment Disorder, Anorexia Nervosa, Borderline Personality Disorder, Obsessive-Compulsive Personality Disorder, Schizotypal Personality Disorder, and Avoidant Personality Disorder. Analyses were conducted separately for males and females using a MANOVA design that examined psychopathology severity among the four groups. Adolescents who engaged in past or current suicidal behavior had higher psychopathology severity scores compared to their nonsuicidal peers. Males with current suicidal thoughts who had attempted suicide had the highest levels of psychopathology severity compared to males in the other three groups. Females with a past suicide attempt or current suicidal ideation had higher psychopathology severity scores compared to nonsuicidal females. Results show greater psychopathology in school-based adolescents who have engaged in past and/or current suicidal behavior. The need for clinicians and mental health professionals working with at-risk youth to focus on concurrent psychopathology along with suicidal behavior is discussed.

The "Attenuated Psychosis Syndrome" (APS, sometimes referred to as the "schizophrenia prodrome") is characterized by subthreshold psychotic-like symptoms and functional decline, and is often associated with significant disability. These symptoms may cause impairment and are of further interest due to their predictive relation to schizophrenia and other psychotic disorders. These symptoms currently are not represented in the diagnostic system for mental health, and it is unclear how they are conceptualized by relevant professionals. The current study surveyed a national sample (n=303) of clinical psychologists, psychiatrists, and general practitioners regarding their clinical appraisal of APS. Practitioners were asked to respond to vignettes representing three conditions: psychosis, subthreshold psychosis (indicating 'attenuated' psychosis symptoms), and no psychotic symptoms. Practitioners' responses suggested that APS is viewed consistently with a DSM-IV-TR defined mental disorder and that most clinicians may diagnose this condition as a full threshold psychotic disorder. Findings tentatively suggest that the inclusion of an attenuated psychosis symptoms category in the forthcoming DSM-5 may be helpful in improving diagnostic reliability and facilitating best practice among community practitioners.
