Real-world effectiveness of long acting aripiprazole: Treatment persistence and its correlates in the Italian clinical practice.

OBJECTIVES: To identify the variables that are associated with persistence to Aripiprazole-Long Acting (A-LAI), in adult patients with schizophrenia. METHODS: Observational, retrospective, non-interventional study involving 261 patients with schizophrenia. RESULTS: Eighty-six percent of study subjects were persistent for at least 6 months. All subjects with baseline CGI-S of 1 or 2, 95% of subjects with CGI-S of 3, 86% with CGI-S of 4, 82% of subjects with CGI-S of 5, 73% of subjects with CGI of 6 and 90% of subjects with CGI of 7 were persistent. A-LAI treatment continuation rate was higher in patients with: 1) baseline CGI score ≤ 4; 2) schizophrenia dimension (LDPS) mania score ≤ 5; 3) psychotic spectrum schizoid score ≤ 11. CONCLUSIONS: A relatively high number of patients (n = 225, 86%) were persistent to A-LAI for at least 6 months. Not surprisingly, very severe patients were more unlikely to be persistent. However, it is noteworthy that a large number of subjects with high CGI score at the time when A-LAI was started (82% of subjects with CGI-S of 5, 73% of subjects with CGI of 6 and 90% of subjects with CGI of 7) were persistent. Larger, controlled, prospective and longer studies are warranted.

Randomized trial to evaluate cardiometabolic and endothelial function in patients with plasma HIV-1 RNA suppression switching to darunavir/ritonavir with or without nucleoside analogues.

BACKGROUND: We performed a study to evaluate change in cardiometabolic and endothelial function in HIV-infected patients switching to darunavir/ritonavir (DRV/r) monotherapy versus triple therapy. METHODS: The MONARCH trial recruited 30 patients who were taking triple combination therapy and with HIV RNA<40 copies/ mL. Patients were randomized to either DRV/r 800/100 mg once daily (OD) monotherapy or DRV/r 800/100 mg OD plus 2 nucleoside reverse transcriptase inhibitors (NRTIs). The primary objective was to assess endothelial function change from baseline to 24 and 48 weeks in brachial artery flow-mediated dilation (FMD) test; changes in endothelial precursor cells (EPCs) and circulating endothelial cells (CECs) were secondary objectives. RESULTS: At baseline, the median age of participants was 43 years, 77% were men, and median CD4 cell count was 585 cells/µL. The median FMD (%) decreased in both arms in the study period (P ≯ .05), with no statistically significant difference between arms (10.7% at baseline and 6.7% at week 48 in the DRV/r + 2 NRTIs arm; 11.1% at baseline and 8.8% at week 48 in the DRV/r arm). The changes at week 48 were similar in the 2 arms for EPCs and CECs. Total cholesterol and low-density lipoprotein (LDL) cholesterol showed larger rises to week 48 in the DRV/r arm monotherapy group than in the triple-therapy group (+26 vs +9 mg/dL for total cholesterol and +14 vs +5 mg/dL for LDL cholesterol). CONCLUSIONS: In the MONARCH trial, switching from triple combination treatment to DRV/r, with or without nucleoside analogues, did not translate into clinically meaningful reductions in endothelial function as measured by FMD.
