There are also inconsistent findings regarding the relationships amongst pathophysiology, prognosis, and symptom severity of schizophrenia and blood levels of progesterone, testosterone, and cortisol.10?two The majority of the research within this subfield investigated these relationships by measuring blood levels of patients with schizophrenia, no matter their therapy status, the number of previous episodes, and other confounding factors.3,13?six Moreover, patients with schizophrenia had been often compared with healthful subjects. These studies didn’t measure alterations of blood levels of neuroactive steroids in different phases of the illness or examine blood levels of first-episode and later-episode individuals. Within the present study, we assessed prospective differences in blood levels of DHEA-S, adrenocorticotropic hormone (ACTH), testosterone, progesterone, and cortisol among drug-na e first-episode sufferers with schizophrenia (FES) and drug-free individuals with schizophrenia who were not within the first episode but were inside a phase of acute exacerbation (DFP).The exclusion criteria have been 1) female sex, two) the presence of any other psychiatric morbidity, for example alcohol or substance dependence, three) the presence of any concurrent healthcare or endocrine disorder, and four) the administration of other medications that could alter neurosteroid levels.ProcedureAll sufferers were clinically examined and individually interviewed. To get an objective history in the sufferers, accompanying close relatives had been also interviewed. The sufferers had been rated together with the Scale for the Na+/Ca2+ Exchanger Purity & Documentation Assessment of Adverse Symptoms (SANS)18 plus the Scale for the Assessment of Positive Symptoms (SAPS).19 Prior to initiating any pharmacological therapy, ten mL of venous blood was collected at eight am and divided into one tube with 2 heparin and yet another tube with ethylenediaminetetraacetic acid; this process was essential to measure ACTH. Plasma levels of ACTH (typical variety 7.2?3.3 pg/mL), cortisol (typical variety six.7?two.six /dL), testosterone (regular range eight.9?two.5 pg/mL), progesterone (regular variety 0.14?.06 ng/mL), and DHEA-S (typical variety 85?90 /dL) had been measured by radioimmunoassay. Plasma levels of ACTH, cortisol, testosterone, progesterone, and DHEA-S have been also collected from the consenting healthy subjects and measured using precisely the same assay. To avoid interassay variability, the hormone levels in all groups have been measured simultaneously.Supplies and strategies ParticipantsThis study was carried out inside the inpatien.
