RESUMEN
Several studies indicate the impact of antipsychotics like risperidone and paliperidone on oxidative stress parameters, yet data remain inconsistent. We investigated the link between these medications, hyperprolactinemia (HPRL), and oxidative stress. This study was conducted at the Psychiatry Clinic, University Clinical Center, Kragujevac, between November 2022 and August 2023. Inclusion criteria comprised diagnosed psychotic disorders from the ICD-10-based F20-F29 spectrum and clinical stability on risperidone/paliperidone for ≥12 weeks with no recent dose adjustments. Exclusion criteria included pregnancy, breastfeeding, relevant medical conditions, or co-therapy with prolactin-secreting drugs. Data encompassed drug choice, administration method, therapy duration, and daily dose. Prolactin (PRL) levels, oxidative stress parameters (TBARS, H2O2, O2-, NO2-), and antioxidant system (CAT, GSH, SOD) were assessed. Of 155 subjects, women exhibited significantly higher PRL levels (p < 0.001) and symptomatic HPRL (p < 0.001). Drug choice and regimen significantly influenced TBARS (p < 0.001), NO2- (p < 0.001), O2- (p = 0.002), CAT (p = 0.04), and GSH (p < 0.001) levels. NO2- levels were affected by drug dose (p = 0.038). TBARS (p < 0.001), O2- (p < 0.001), and SOD (p = 0.022) inversely correlated with PRL levels, suggesting PRL's protective role against oxidative stress. The female sex association with higher PRL levels implies additional factors influencing PRL's antioxidant role. Antipsychotic choice and dosage impact PRL and oxidative stress markers, necessitating further exploration.
RESUMEN
Depression symptoms take place recurrently in patients suffering from COPD. This study aims to assess the effects of antidepressant therapy in patients with COPD and a depressive disorder in relation to COPD levels. The study population consisted of N = 87 patients diagnosed with COPD, according to the GOLD criteria, and a depressive disorder. All of the patients were subjected to clinical and psychiatric exploration according to psychiatric assessment instruments, which was followed by SSRI therapy for the duration of 8 weeks. The main methods used were descriptive statistics and analysis of variance. The results showed a different distribution of depressive symptoms at a different stage of COPD by FEV1 (χ2 = 30.47, df = 6, p < 0.01) and by mMRC (χ2 = 34.6, df = 6, p < 0.01). After the application of SSRIs, there was a significant improvement in HDRS scores in all stages of COPD by FEV1 (χ2 = 251.62, df = 9, p < 0.01) and by mMRC (χ2 = 919.17, df = 9, p < 0.01). This study contributes to the improvement in the quality of life of patients by the targeted application of SSRI therapy and, therefore, more precise and better overall treatment results.
RESUMEN
Since the end of 2019, the global spread of COVID-19 has represented a historic event that changed our way of treating patients globally. The use of long-acting injections (LAI) antipsychotics was emphasized. Our goal was to investigate the impact of COVID-19 on the frequency of prescribing LAI and compare it with a period before. All patients (198) who started LAI-risperidone or LAI-paliperidone for the period 2017-2022, in Kragujevac, the city in Central Serbia, were considered. The frequency of prescribing LAI before and during COVID-19 and the total number of prescribed LAI per year were compared. Separately, the frequency of prescribing LAI-R and the frequency of prescribing LAI-P were compared. The significant (p < 0,05) increase in the use of LAI risperidone and paliperidone was in 2020 and 2021 [per year 2017(3), 2018(6), 2019(26), 2020(75), 2021(55), and 2022(33)]. The significant (p < 0,05) increase in monthly and quarterly preparations of LAI paliperidone was in 2020 and 2021 relative to the years before the pandemic. As the pandemic weakened, the inclusion of LAI paliperidone therapy weakened during 2022. A significant increase in usage of LAI risperidone was in 2022, and in 2020 and 2021 was as it was in the period 2017-2019. During COVID-19, especially in years when COVID-19 restriction measures were stricter, there was a significant change in the application method of antipsychotic therapy in favor of LAI. Regardless of the increase in treatment costs, patients' interests and protection were prioritized in the treatment process.
