Abstract

Calcium balance and regulation play an important role in providing its normal plasma concentration. Hormonal regulation is mostly done by parathormone and vitamin D. Impaired balance may result in bone demineralization, decreased bone mineral density and cause osteopenia and osteoporosis. In patients with a diagnosis of schizophrenia it can be due to dietary and vitamin deficiencies, decreased sunshine exposure, as well as polydipsia and other reasons. There is no substantial data exploring the influence of second generation antipsychotics on calcium dynamics in schizophrenic patients. The aim of the study was to evaluate calcium and phosphate metabolism in patients with a diagnosis of schizophrenia treated with second generation antipsychotics in reference to a control group of healthy, non-medicated volunteers. Participants in the study were 60 schizophrenic patients: 26 were treated with risperidone, 34 with olanzapine and 38 were healthy, non-medicated volunteers--the control group. Subjects were excluded for any medical condition or treatment known to alter calcium balance. Blood samples for analysis were fasting morning ones. The following parameters were measured: serum levels of ionized calcium and phosphate, serum leve...Continue Reading
