Benefits of Individualized Counseling by the Pharmacist on the Treatment Outcomes of Hyperlipidemia in Hong Kong

A prospective controlled study on the benefits of pharmacists' individualized counseling on drug compliance, cholesterol concentration reduction, attainment of National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) low-density lipoprotein cholesterol (LDL-C) goals, and patient satisfaction was carried out in a private community hospital in Hong Kong. All patients who were newly prescribed with lipid-lowering drugs for primary prevention were included. The patients in the individualized counseling group received "intense" counseling and follow-up of cholesterol concentration by a pharmacist for 3 months. The control group received routine counseling. Fifty patients completed the study (26 in the individualized group, 24 in the control group). Compliance was assessed, and those patients who achieved 75% compliance were defined as compliers. In the individualized group, 76.9% were compliers compared with 41.7% in the control group (p < 0.01). The individualized group achieved 28.3%, 27.7%, and 26.1% reduction in total cholesterol, LDL-C, and triglycerides, respectively, compared with 15.3%, 16.3%, and 10.6% in the control group (p < 0.05 for all). Also in the individualized group, 80.8% achieved the ATP III LDL-C goals compared to 58.3% in the control group (p < 0.05). Of patients in the individualized group, 85% felt that the pharmacist counseling service could improve their disease management. The study demonstrated that pharmacists' individualized counseling, together with the assessment of cholesterol concentrations, had positive impacts on the management of hyperlipidemia, including improved drug compliance, better treatment endpoints, and patient satisfaction.

Lovastatin modulation of microglial activation via suppression of functional CD40 expression

Recent studies have shown that the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) possess antiinflammatory and immunomodulatory properties, distinct from their action of lowering serum lipid levels. Moreover, results of epidemiological studies suggest that long-term use of statins is associated with a decreased risk for Alzheimer's disease (AD). Interestingly, lovastatin (one of the most commonly used anticholesterol drugs) treatment of vascular-derived cells has been reported to antagonize activation of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathway, and it is well known that the JAK/STAT pathway plays a central role in interferon-gamma (IFN-gamma)-induced microglial CD40 expression. We and others have previously reported that microglial CD40 expression is significantly induced by IFN-gamma and amyloid-beta (Abeta) peptide. Moreover, it has been shown that CD40 signaling is critically involved in microglia-related immune responses in the CNS. In this study, we examined the putative role of lovastatin in modulation of CD40 expression and its signaling in cultured microglia. RT-PCR, Western immunoblotting, and flow cytometry data show that lovastatin suppresses IFN-gamma-induced CD40 expression. Additionally, lovastatin markedly inhibits IFN-gamma-induced phosphorylation of JAK/STAT1. Furthermore, lovastatin is able to suppress microglial tumor necrosis factor-alpha, interleukin (IL)-beta1 and IL-6 production promoted either by IFN-gamma or by Abeta peptide challenge in the presence of CD40 cross-linking. To characterize further lovastatin's effect on microglial function, we examined microglial phagocytic capability following CD40 cross-linking. Data reveal that lovastatin markedly attenuates CD40-mediated inhibition of microglial phagocytosis of Abeta. These results provide an insight into the mechanism of the beneficial effects of lovastatin in neurodegenerative disorders, particularly Alzheimer's disease.

Adherence to antipsychotic and nonpsychiatric medications in middle-aged and older patients with psychotic disorders

OBJECTIVE

The prevalence and consequences of nonadherence to antipsychotic medications in schizophrenia and related psychotic disorders have been well described; however, little is known about adherence to medications for nonpsychiatric conditions in patients with psychotic disorders. We wished to determine medication adherence in nondemented middle-aged and older Veterans Affairs outpatients with schizophrenia or other psychotic disorders who had been prescribed oral medications for hypertension, hyperlipidemia, or diabetes.

METHODS

Medication adherence was assessed by review of medication fill records for 76 patients aged 40 years and older who had been prescribed an oral antipsychotic in addition to an oral agent for hypertension (N = 60), hyperlipidemia (N = 28), or diabetes (N = 24). Up to 12 months of therapy was reviewed, and a compliant fill rate (the number of adherent fills in proportion to the total number of prescription fills) and cumulative mean gap ratio (the number of days when medication was unavailable in relation to the total number of days) were calculated for each medication.

RESULTS

The 12-month mean compliant fill rates for antipsychotics, antihypertensives, antihyperlipidemics, and antidiabetics ranged from 52% to 64%. Nonpsychiatric medication adherence rates were similar in patients on typical vs. atypical antipsychotics and did not correlate significantly with antipsychotic adherence rates.

CONCLUSIONS

Nonadherence rates were found to be equally problematic for both antipsychotic and nonpsychiatric medications in middle-aged and older patients with psychotic disorders. Interventions to improve adherence to both antipsychotic and nonpsychiatric medications are needed.
