Factors Correlated to the Renoprotective Effect of Sitagliptin in Patients with Type 2 Diabetes Mellitus: Retrospective Observational Study.

Background: Sitagliptin functions similarly to GLP-1RAs by incretin and insulin secretion and has a renoprotective effect. Diabetic kidney disease (DKD) is a kidney complication that increases the mortality rate in type 2 diabetes mellitus (T2DM) patients. The important parameters that predict appropriate sitagliptin treatment are known as factors. This study aimed to assess factors that correlated with the renoprotective effect of sitagliptin in patients with T2DM. Methods: This retrospective study collected data from a tertiary hospital in Thailand. All T2DM patients who were treated with sitagliptin and had complete data were recruited to analyze the outcome. The primary outcome was a correlation between demographics, laboratory data, and kidney outcome. The secondary outcome was the different laboratory results between pre- and posttreatment of patients treated with sitagliptin. Results: The number of patients who were treated for T2DM with sitagliptin was 191. Only 102 patients had complete laboratory parameters. Results showed a positive correlation between baseline FBS, HbA1c, and Scr change (p value = 0.042 and 0.005) at 6 months and baseline age, TG, and Scr change (p value = 0.010 and 0.022) at 18 months; while a negative correlation was observed between baseline FBS, HbA1c, and eGFR change (p value = 0.017 and 0.007) at 6 months and baseline age and eGFR change (p value = 0.010) and between HDL-cholesterol and Scr change at 18 months (p value = 0.044). The eGFR stage 1 subgroup showed a positive correlation between baseline HbA1c and Scr change (p value <0.001) and baseline DM duration and eGFR change (p value = 0.004). Moreover, sitagliptin showed statistically significant FBS, HbA1c, LDL-cholesterol, and TC reduction. Furthermore, HDL-cholesterol showed statistically significant elevation. Conclusion: FBS, HbA1c, and age were factors that correlated with the renoprotective effect of sitagliptin. The eGFR ≥90.00 ml/min/1.73 m2 patients group showed a duration of DM in which factors correlated with renoprotective effect. Moreover, sitagliptin also can improve glucose levels and lipid profile.

Potential Drug Interaction Between Favipiravir and Warfarin in Patients With COVID-19: A Real-World Observational Study.

Favipiravir is one of the most used antiviral agents for the treatment of coronavirus disease 2019 infection in many countries, including Thailand. This study aimed to investigate the effect of favipiravir-warfarin interaction in terms of changes in international normalized ratio (INR) of patients. Medication charts of all inpatients in a hospital in Thailand between April 2021 and March 2022 were reviewed. Patients who received either warfarin with standard care or warfarin with favipiravir were included. The INR levels of patients were monitored at baseline and the earliest date following treatment, as well as other laboratory parameters. There were 43 and 53 patients in the warfarin-favipiravir and the warfarin-only groups, respectively. Baseline characteristics, such as sex, age, body mass index, and warfarin dose, were not significantly different between the 2 groups. The results showed that the mean INR of patients using favipiravir and warfarin was increased from 2.14 to 3.88 (P < .001), while the patients using warfarin alone had no increase in the mean INR (1.93 vs 1.91; P = .906). Other parameters were not significantly changed, including white blood cell count, red blood cell count, hemoglobin, hematocrit, and liver function. However, an increase in platelet count was observed in the favipiravir-warfarin group, but not in the control group. This real-world study highlighted a significant increase in the INR levels of patients who used favipiravir together with warfarin, compared to patients who used only warfarin. However, the interaction did not affect other laboratory parameters, except an increase in platelet count.

Desires and Attitudes towards Telepharmacy Medicine Delivery.

The COVID-19 pandemic has limited healthcare services for patients with non-communicable diseases (NCDs). Hospital pharmacy departments in Thailand apply a new normal pharmacy service known as "telepharmacy" to serve remote pharmacy practice and deliver medication to patients. Current knowledge clearly shows the benefit of each medicine delivery method, but the study of patient's desires and attitudes towards all drug delivery methods is still limited. To fill the gap, this study aims to investigate desires and attitudes about drug delivery methods among Thai patients living with NCDs who need regular and continuous care. The sample was included by accidentally randomized technique at NCD clinics of the southern Thailand tertiary care hospital. Data were collected between January and March 2021 by a questionnaire that contained three sections: the currently received medicine delivery method, the desires and attitudes about the medicine delivery system, and patients' demographic information. The majority of patients were women aged 60 years who earned less than 10,000 THB (263.85 USD), were enrolled in the Civil Servant Medical Benefit Scheme (CSMBS), lived 0-15 km from the hospital, living with hypertension, had 1-4 prescribed medications, visited the doctor every 3 months, and received the conventional drug delivery method. The result showed that only the subdistrict health promotion hospital (SHPH) medicine delivery method was at a high level of desire, while the rest including conventional, drug store, postal pharmacy, and drive-thru medicine delivery methods were at medium. Attitudes toward the quality of medicine delivery methods consisted of five dimensions: confidence, timeliness, reliability, empathy, and facilities. Thai NCD patients had positive attitudes toward SHPH and drug store medicine delivery methods that could be seen from the high level of attitude score across all dimensions, while postal pharmacy and drive-thru delivery methods received medium-level attitude scores across all five dimensions.

Efficacy of linagliptin on cardiovascular risk and cardiometabolic parameters in Thai patients with type 2 diabetes mellitus: A real-world observational study.

BACKGROUND AND AIMS: There is no published data on linagliptin, a dipeptidyl peptidase-4 inhibitor, on its cardiovascular risk reduction in Thai population. This study, therefore, aimed to investigate the effect of linagliptin on cardiovascular risk reduction in Thai patients with diabetes mellitus. METHODS: Patient profiles of all patients treated with linagliptin in a hospital in Thailand were reviewed. Patients who had used linagliptin for at least 12 months were recruited for analysis. Their cardiovascular risk scores were calculated using the Atherosclerotic Cardiovascular Disease Risk Estimator Plus tool and were compared between pre-treatment and 12-month post-treatment of linagliptin. RESULTS: There were a total of 73 patients recruited for analysis. At 12 months of treatment, the results indicated no significant reduction in the cardiovascular risk score of all patients compared to pre-treatment (25.67% vs. 23.37%, p-value 0.442). The atherosclerotic cardiovascular disease risk reduction with linagliptin was significantly higher in patients with high baseline atherosclerotic cardiovascular disease risk and in the elderly population. A significant reduction in patients with ≥20% baseline cardiovascular risk score (6.36% decrease, p-value 0.017) was observed. Significant decreases in fasting blood sugar, haemoglobin A1c, and triglyceride were observed, but not in total and LDL-cholesterol levels. Additionally, HDL-cholesterol was significantly increased. CONCLUSIONS: The mean cardiovascular risk score of all patients was not significantly changed with 12-month linagliptin treatment. However, linagliptin could significantly reduce the 10-year cardiovascular risk score in patients with ≥20% baseline risk. Also, patients with advanced age gained more benefit from linagliptin treatment. A limitation of this study was the drugs which might affect cardiovascular risk were not collected at 12-month post-treatment.

Efficacy of vildagliptin on 10-year cardiovascular risk reduction in Thai patients with type 2 diabetes mellitus: A real-world observational study.

BACKGROUND AND AIMS: This study aimed to assess the effects of vildagliptin on the prevention of cardiovascular diseases in Thai patients with type 2 diabetes mellitus using the Thai Cardiovascular Risk Score. METHODS: All patients with type 2 diabetes mellitus who used vildagliptin at a secondary hospital in Thailand were screened and recruited. The relevant variables were obtained from patient medication charts at the first visit on which the patients were prescribed vildagliptin and from the 6-month, 12-month, and 18-month post-treatment visits. The Thai Cardiovascular Risk Score was calculated and monitored as a primary outcome, whereas changes in separate cardiometabolic parameters were assessed as secondary outcomes. RESULTS: Of the 321 patients screened, only 95 were recruited for the analysis. The average 10-year cardiovascular risks of patients increased from 19.65% at baseline to 20.74%, 20.69%, and 23.78% at 6, 12, and 18 months post treatment, respectively. However, a better trend of reduction in cardiovascular risk was observed in patients with a high baseline cardiovascular risk. The glucose-lowering effects of vildagliptin were significantly observed 12 months of treatment onwards, but non-significant changes were found in lipid and blood pressure levels as well as body mass index. CONCLUSION: Vildagliptin provided a promising glucose-lowering effect in Thai patients with type 2 diabetes mellitus. However, the mean 10-year cardiovascular risk did not significantly decrease. However, a negative correlation between cardiovascular risk reduction and baseline cardiovascular risk was observed in this study. Low sample size was a major limitation of this study.
