Toxoplasma gondii (T.gondii) is an obligate intracellular protozoan that infects warm-blooded animals and has a global distribution. Acute toxoplasmosis is commonly reported in patients with acquired/congenital toxoplasmosis and immune deﬁciency. New methods are needed to prevent the sideffects of classical treatment. In this study, Rosuvastatin loaded chitosan nanoparticle (CH-NP-ROS) were synthesized and zeta potential and size were determined, and an MTT assay was performed to evaluate the cell toxicity on Macrophage cells (MQ) and anti-Toxoplasma activity using Trypan-blue staining by different concentrations of Rosuvastatin (ROS), and Rosuvastatin loaded chitosan nanoparticle (CH-NP-ROS). The cell viability assay demonstrated that CH-NP-ROS had lower cell toxicity (<15 %) compared to ROS (<30 %). Statistical analysis showed that CH-NP-ROS significantly killed 98.950 ± 1.344; P < 0.05) of Toxoplasma gondii tachyzoites. In vivo results of perituneal fluid showed that CH-NP significantly reduced the parasite load in the CH-NP-ROS group, compared to that in negative control group (P < 0.001). Growth inhibition rates of tachyzoites in mice receiving free ROS and CH-NP-ROS (injection and oral form) were found to be 166.125 + 4.066, 118.750 + 4.596 and 124.875 + 2.652, respectively, compared to mice in Sulfadiazine/Pyrimethamine treated group (positive control). In the infected untreated mice (control +), the mean tachyzoite counts per oil immersion field in the spleen was 8.25 respectively. The mean survival time in all the groups treated with ROS and CH-NP-ROS was longer than that in the negative control group Therefore, nanoformulation is a promising approach for the delivery and is safe for using therapeutic effects in acute toxoplasmosis.

AbstractAimsTo compare medication adherence, lipid goal attainment, and healthcare costs between patients receiving a single-pill combination (SPC) vs. a free combination treatment (FCT) of rosuvastatin/ezetimibe (ROS/EZE) in Italy.Methods and resultsAdministrative databases of healthcare entities covering ∼7 million individuals were used to identify adults prescribed with ROS/EZE as SPC or FCT between January 2018 and June 2020. Adherence was calculated as the proportion of days covered (PDC) after cohort balancing by propensity score matching. Patients with available LDL cholesterol testing were assessed for the proportion of those who at baseline were above lipid targets recommended by ESC/EAS Guidelines for their cardiovascular risk category and reached the target during follow-up. Among 25 886 patients on SPC and 7309 on FCT, adherent patients were more represented in SPC than FCT cohort (56.8 vs. 44.5%, P < 0.001), and this difference remained significant (P < 0.001) after stratification by cardiovascular risk (very high, high, and other). The proportion of patients reaching LDL cholesterol target at 1 year follow-up was significantly (P < 0.001) higher in SPC vs. FCT cohort: 35.4 vs. 23.8% for very high cardiovascular risk, 46.9 vs. 23.1% for high risk and 71.6 vs. 49.5% for other risk. Total healthcare costs per patient at 1 year follow-up were lower in SPC vs. FCT users (2337€ vs. 1890€, P < 0.001). In both cohorts, costs were mainly driven by drug expenses and hospitalizations.ConclusionThis real-world analysis in dyslipidaemic patients found that treatment with ROS/EZE as SPC resulted in better adherence, higher chances of reaching lipid goals, and cost savings over FCT, in all cardiovascular risk categories.

Differential Adherence to Free and Single-Pill Combination of Rosuvastatin/Ezetimibe: Findings from a Real-World Analysis in Italy

INTRODUCTIONAdherence to cardiovascular drug treatment can significantly benefit from a reduced pill burden, but data on this matter derived from real-life settings are currently scanty. This analysis assessed the possible changes in adherence in patients treated with rosuvastatin and ezetimibe (ROS/EZE) as free multi-pill combination who switched to ROS/EZE as single-pill combination in the setting of real clinical practice in Italy.METHODSA retrospective analysis was conducted on the administrative databases for a catchment area of about seven million health-assisted residents. Adults receiving ROS/EZE as a single-pill combination from January 2010 to June 2020 (followed up to 2021) were identified. The date of the first prescription of single-pill combination of ROS/EZE was considered as the index date. The analysis included the users of ROS/EZE as a free combination during the year before the index date. Baseline demographic and clinical characteristics were collected during the period of data availability prior to the index date. Adherence to therapy was evaluated as proportion of days covered (PDC), namely the percentage of days during which a patient had access to medication, in the 12-month interval preceding or following the index date (PDC < 25% non-adherence; PDC = 25-75% partial adherence; PDC > 75% adherence).RESULTSA total of 1219 patients (61.1% male, aged 66.2 ± 10.4 years) were included. Cardiovascular comorbidities were found in 83.3% of them, diabetes in 26.4%, and a combination of both in 16.2%. Single-pill combination of ROS/EZE was associated with a higher proportion of adherent patients compared to free-pill combination (75.2% vs 51.8%, p < 0.001).CONCLUSIONSThis real-world analysis suggested that switching from a regimen based on separate pills to one based on a single-pill combination resulted in improved adherence to ROS/EZE therapy.
