Influence of Treatment Intensification on A1c in Patients with Suboptimally Controlled Type 2 Diabetes After 2 Oral Antidiabetic Agents

Decoding the chemical composition and pharmacological mechanisms of Jiedu Tongluo Tiaogan Formula using high-performance liquid chromatography coupled with network pharmacology-based investigation

Type 2 diabetes mellitus (T2DM), a chronic low-grade inflammatory disease with high morbidity and mortality, is a serious threat to public health. Previously we demonstrated that a traditional Chinese medicine formulation, Jiedu Tongluo Tiaogan Formula (JDTL), exerted a favorable hypoglycemic effect due to unknown molecular mechanisms involving interactions among JDTL compounds and various cellular components. This study aimed to explore JDTL mechanisms for alleviating hyperglycemia using an integrated strategy incorporating system pharmacology, bioinformatics analysis, and experimental verification. This strategy entailed initial elucidation of JDTL chemical composition using fingerprint analysis via high performance liquid chromatography (HPLC). Next, functions of putative shared target genes and associated pathways were deduced using GO and KEGG pathway enrichment and molecular docking analyses. Ultimately, targets associated with JTDL anti-T2DM effects were found to be functionally associated with biological functions related to lipopolysaccharide and cytokine receptor binding. These results implicated PI3K-Akt signaling pathway involvement in JDTL anti-T2DM effects, as this pathway had been previously shown to play significant roles in glucose and lipid metabolism-related diseases. Furthermore, addition of JDTL to INS-1 and HepG2 cell cultures stimulated cellular mRNA-level and protein-level expression leading to enhanced production of IRS1, Akt, and PI3K. In summary, here JDTL bioactive ingredients, potential targets, and molecular mechanisms underlying JDTL anti-T2DM effects were identified using a multi-component, multi-target, and multi-channel analytical approach, thus providing an important scientific foundation to facilitate development of new drugs mechanistic strategies for preventing and treating T2DM.

Measurement of Pharmacist-Physician Collaborative Care on Therapeutic Inertia in Patients With Type 2 Diabetes

BACKGROUND

Team-based care practice models have been shown to improve diabetes-related therapeutic inertia, yet the method and type of antidiabetic treatment intensification (TI) leading to improvements in glycemic control are not well understood.

OBJECTIVE

To evaluate time to TI in a pharmacist-physician practice model (PPM) as compared with usual medical care (UMC), explore the method and type of antidiabetic TI, and evaluate achievement of hemoglobin A_1C (A1C) goal among each cohort.

METHODS

This was a retrospective cohort study conducted between January 1, 2017, and December 31, 2018. Median time to TI was calculated and compared between patients in the PPM and UMC groups using the log rank test. Descriptive statistics were used to evaluate the method and type of TI and A1C goal achievement.

RESULTS

A total of 56 patients were included. The median (interquartile range) time to antidiabetic TI among the PPM cohort was 37.5 days (8, 216.5), as compared with 142 days (16, 465) in the UMC cohort (P = 0.19). At 1 year post-index date, 25% of patients in the PPM cohort reached their A1C goal compared with 18.8% of patients in the UMC cohort. This effect was maintained in the subgroup (n = 49) of patients receiving TI (23.1% vs 17.8%).

CONCLUSION AND RELEVANCE

A shorter time to TI and improvement in A1C goal achievement was observed with pharmacist-physician care compared with UMC. These findings suggest that pharmacist-physician care may be one of several interventions necessary to overcome therapeutic inertia in diabetes care.
