Hypertension and Type 2 Diabetes-The Novel Treatment Possibilities

Ileum excision partially reverses improvement of glucose metabolism in diabetic rats after biliopancreatic diversion with duodenal switch

BACKGROUND

Bile acids can stimulate the secretion of glucagon-like peptide-1 (GLP-1) and be mostly reabsorbed in the ileum.

OBJECTIVES

We aimed to investigate whether ileum excision could reverse the glucose improvement after biliopancreatic diversion with duodenal switch (BPD/DS).

SETTING

Peking Union Medical College Hospital.

METHODS

Thirty diabetic rats were randomly divided into the BPD/DS group, BPD/DS plus ileectomy (BDI) group, and control group. The fasting blood glucose, bile acids, and glucagon-like peptide-1(GLP-1) levels in plasma samples were analyzed.

RESULTS

In postoperative week 20, the fasting blood glucose level in the BDI group was significantly higher than that in the BPD/DS group (11.5 ± 1.4 mmol/L versus 7.6 ± 1.0 mmol/L, P < .001), and the AUCOGTT value was also significantly higher than that in the BPD/DS group (2186.1 ± 237.2 mmol/L·min versus 1551.2 ± 136.9 mmol/L·min, P < .001). The plasma level of bile acids in the BDI group was lower than that in the BPD/DS group (P = .012) and was not significantly different from that in the control group (P = .629). The plasma level of GLP-1 in the BDI group was lower than that in the BPD/DS group (P = .009) and was not significantly different from that in the control group (P = .530). Moreover, the intestinal TGR5 expression in the BDI group was significantly lower than that in the BPD/DS group (P < .001).

CONCLUSIONS

The results show that excision of the ileum can partially reverse the improvement in glucose metabolism after BPD/DS.

Vasorelaxant and Blood Pressure-Lowering Effects of Cnidium monnieri Fruit Ethanol Extract in Sprague Dawley and Spontaneously Hypertensive Rats

Cnidium monnieri (L.) Cusson, a member of the Apiaceae family, is rich in coumarins, such as imperatorin and osthole. Cnidium monnieri fruit (CM) has a broad range of therapeutic potential that can be used in anti-bacterial, anti-cancer, and sexual dysfunction treatments. However, its efficacy in lowering blood pressure through vasodilation remains unknown. This study aimed to assess the potential therapeutic effect of CM 50% ethanol extract (CME) on hypertension and the mechanism of its vasorelaxant effect. CME (1-30 µg/mL) showed a concentration-dependent vasorelaxation on constricted aortic rings in Sprague Dawley rats induced by phenylephrine via an endothelium-independent mechanism. The vasorelaxant effect of CME was inhibited by blockers of voltage-dependent and Ca2+-activated K+ channels. Additionally, CME inhibited the vascular contraction induced by angiotensin II and CaCl2. The main active compounds of CM, i.e., imperatorin (3-300 µM) and osthole (1-100 µM), showed a concentration-dependent vasorelaxation effect, with half-maximal effective concentration values of 9.14 ± 0.06 and 5.98 ± 0.06 µM, respectively. Orally administered CME significantly reduced the blood pressure of spontaneously hypertensive rats. Our research shows that CME is a promising treatment option for hypertension. However, further studies are required to fully elucidate its therapeutic potential.

Prediction of glycosylated hemoglobin level in patients with cardiovascular diseases and type 2 diabetes mellitus with respect to anti-diabetic medication

Blood glycosylated hemoglobin level can be affected by various factors in patients with type 2 diabetes and cardiovascular diseases. Frequent measurements are expensive, and a suitable estimation method could improve treatment outcomes.

Patients and methods

93 patients were recruited in this research. We analyzed a number of parameters such as age, glucose level, blood pressure, Body Mass Index, cholesterol level, echocardiography et al. Patients were prescribed metformin. One group (n=60) additionally was taking sitagliptin. We applied eight machine learning methods (k nearest neighbors, Random Forest, Support Vector Machine, Extra Trees, XGBoost, Linear Regression including Lasso, and ElasticNet) to predict exact values of glycosylated hemoglobin in two years.

Results

We applied a feature selection approach using step-by-step removal of them, Linear Regression on remaining features, and Pearson's correlation coefficient on the validation set. As a result, we got four different subsets for each group. We compared all eight Machine Learning methods using different hyperparameters on validation sets and chose the best models. We tested the best models on the external testing set and got R2 = 0.88, C Index = 0.857, Accuracy = 0.846, and MAE (Mean Absolute Error) = 0.65 for the first group, R2 = 0.86, C Index = 0.80, Accuracy = 0.75, and MAE = 0.41 for the second group.

Conclusion

The resulting algorithms could be used to assist clinical decision-making on prescribing anti-diabetic medications in pursuit of achieving glycemic control.

Impact of calcium channel blockers and angiotensin receptor blockers on hematological parameters in type 2 diabetic patients

Antihypertensive medications have been associated with a reduction in hemoglobin (Hb) levels, leading to clinically significant anemia. We aimed to provide valuable insights into the impact of angiotensin receptor blockers (ARBs) and calcium channel blockers (CCBs) on hematological parameters by measuring the levels of erythropoietin (EPO), ferritin, and complete blood count (CBC) in individuals with type 2 diabetes mellitus (T2DM), particularly considering the duration of the antihypertensives use. In addition to comparing their effects on blood pressure, glycemic status, and renal function, a retrospective cohort study was conducted at the consultation unit of Alsalam Teaching Hospital, Mosul, Nineveh Province, between October 2022 and February 2023. A total of 160 participants were enrolled after being fully examined by the consultants to detect their eligibility for inclusion in the study and to rule out any abnormality. They consisted of 40 healthy controls, 30 T2DM patients (T2DM group), 30 T2DM patients with newly diagnosed hypertension (HT) (T2DM+HT group), 30 type 2 diabetic-hypertensives on ARBs (T2DM+HT+ARBs group), and 30 type 2 diabetic-hypertensives on CCBs (T2DM+HT+CCBs group). Five milliliters of blood was drawn from a vein and divided into two parts. Two milliliters was transferred into an anticoagulant tube for the measurement of HbA1c and complete blood picture. Serum was obtained from the remaining blood and used for assessment of ferritin, EPO, FSG, creatinine, urea, and uric acid. Significantly reduced FSG and HbA1c levels were observed in T2DM+HT+CCBs and T2DM+HT+ARBs groups vs T2DM+HT group (p < 0.05). The T2DM+HT+CCBs group had statistically higher urea levels than the T2DM group (p < 0.05). Both CCBs and ARBs use resulted in reduced creatinine clearance (CrCl). T2DM+HT+CCBs group exhibited slightly higher uric acid levels compared to controls (p < 0.05). Prolonged use of CCBs and ARBs led to disturbances in hematological parameters, with CCBs users showing the lowest levels of hemoglobin (Hb), RBCs, and hematocrit (Hct) among the groups. ARBs users displayed the lowest values of EPO and ferritin compared to other patient groups, along with reduced levels of Hb, RBCs, and Hct, albeit slightly higher than CCBs users. Our study highlights the importance of a balanced approach in prescribing ARBs and CCBs to patients with T2DM, given their potential to induce blood abnormalities, particularly with prolonged usage.

Severity of fatty liver is highly correlated with the risk of hypertension and diabetes: a cross-sectional and longitudinal cohort study

BACKGROUND AND AIMS

Fatty liver disease (FLD) is associated with several metabolic derangements. We conducted a retrospective cross-sectional and longitudinal study to evaluate the role of FL severity in the risk of new-onset and co-existing hypertension (HTN) and diabetes mellitus (DM).

METHODS

The cross-sectional cohort consisted of 41,888 adults who received health checkups in a tertiary hospital of Taiwan from 1999 to 2013. Of them, 34,865 without HTN and/or DM at baseline and within 1 year after enrollment were included as a longitudinal cohort (mean, 6.45 years for HTN; 6.75 years for DM). FL severity based on the degree of hepatic steatosis was assessed by ultrasound sonography.

RESULTS

In cross-sectional cohort, 22,852 (54.6%) subjects had FL (18,203 [43.46%] mild FL and 4,649 [11.10%] moderate/severe FL); 13.5% (n = 5668) had HTN; and 3.4% (n = 1411) had DM. Moderate/severe FL and mild FL had significantly higher risks of existing HTN (adjusted odds ratio/95% confidence interval [CI] 1.59/1.43-1.77 and 1.22/1.13-1.32, respectively). In longitudinal cohort, 3,209 and 822 subjects developed new-onset HTN and DM, respectively (annual incidence, 14.3 and 3.5 per 1000 person-years; 10-year cumulative incidence, 14.35% and 3.89%, respectively). Moderate/severe and mild FL had significantly higher risks of new-onset HTN (adjusted hazard ratio [aHR]/CI 1.54/1.34-1.77 and 1.26/1.16-1.37, respectively) and DM (aHR/CI 5.88/4.44-7.81 and 3.22/2.56-4.07, respectively). Resolved FL during follow-up decreased the risk of HTN and/or DM.

CONCLUSIONS

Patients with FL are at high risk of prevalent and incident HTN and/or DM. The risk increases with the severity of FL.

The vascular complications of diabetes: a review of their management, pathogenesis, and prevention

INTRODUCTION

This review highlights the pathogenesis of both microvascular and macrovascular complications of diabetes and how these mechanisms influence both the management and preventative strategies of these complications. The cumulative data shown in this review suggest hyperglycemic and blood pressure control remain central to this intricate process.

AREAS COVERED

We reviewed the literature including retrospective, prospective trials as well as meta-analysis, and post hoc analysis of randomized trials on microvascular andmacrovascular complications.

EXPERT OPINION

Further research is needed to explore the ideal intervention targets and preventative strategies needed to prevent macrovascular complications. Furthermore, as the data for trials looking at microvascular complications lengthen more long-term data will further elucidate the role that the duration of diabetes has on these complications. Additionally, trials looking to maximize hyperglycemic control with multiple agents in diabetes, such as metformin, SGL2isand GLP-1 receptor agonists are currently in process, which will have implications for rates of microvascular as well as macrovascular complications.

Comparative analysis of sacubitril/valsartan and losartan potassium in the treatment of hypertension: efficacy, adverse reactions, and observations

OBJECTIVE

To explore the antihypertensive effect of sacubitril/valsartan and losartan potassium in the treatment of hypertension and the adverse reactions in patients.

METHODS

A retrospective study was conducted using the medical records of 166 patients with hypertension who were admitted to Hangzhou Fuyang District Lushan sub-district community health service center from June 2022 to June 2023. The control group was treated with losartan potassium, and the observation group was treated with sacubitril/valsartan. Blood pressure, urinary microalbumin, blood urea nitrogen level, liver and kidney function, blood potassium, blood uric acid, cardiac function, inflammatory factors, occurrence of adverse reactions, and treatment efficacy were compared between the two groups.

RESULTS

After treatment, the observation group showed significantly lower blood pressure compared to the control group. Furthermore, the observation group exhibited reduced levels of urinary microalbumin and blood urea nitrogen, improved liver and kidney function, decreased inflammatory factor levels, fewer adverse reactions, and a higher treatment efficacy.

CONCLUSION

For patients with hypertension, sacubitril/valsartan has a better treatment efficacy than losartan potassium, because it can effectively reduce blood pressure, the levels of inflammatory factors, and the rate of adverse reactions in patients.

Seeking Treatment Profile of Male Shift Workers With Hypertension and Diabetes

OBJECTIVE

This study was identified seeking treatment for hypertension and diabetes among male shift workers.

METHOD

This retrospective cohort study included nine large companies in Japan. Data were collected from health checkup, health insurance records, and self-administered questionnaires in 2017 and 2020. Data were analyzed using Kaplan-Meier curves and Cox regression.

RESULT

Person-days shift workers and day workers seeking treatment for hypertension were 41,604 and 327,301, respectively and, for diabetes, were 7326 and 60,735, respectively. The log ranks were statistically significant. Shift workers were 46% and 56% less likely to seek treatment for hypertension and diabetes, respectively, than day workers were after adjustment for age, marital status, education level, and intention to modify lifestyle (model 2) ( P < 0.01).

CONCLUSIONS

Male shift workers are less likely to seek treatment for hypertension and diabetes compared with day workers.

Incidence and Factors Associated with Hyperglycemia in Patients with First Hospitalization for Major Depression Disorder: A Large Cross-Sectional Sample

Purpose

Major depressive disorder (MDD) is a mood disorder characterized by persistent spontaneous depression and has a high rate of disability and mortality. There is a complex relationship between MDD and disorders of glucose metabolism, and our study aimed to investigate the prevalence and risk factors for hyperglycemia in patients with MDD who were hospitalized for the first times.

Patients and Methods

A total of 981 first-time inpatients with MDD were recruited, socio-demographic information, anthropometric data, and biochemical parameters were collected for each participant. The 17-item Hamilton Assessment Scale for Depression (HAMD-17), the 14-item Hamilton Anxiety Scale (HAMA-14), the Positive Syndrome Scale (PSS), and Clinical General Impressions Inventory-Severity of Illness (CGI-SI) scores were used to assess patients' clinical symptoms.

Results

The prevalence of hyperglycemia was 9.28% among patients with MDD who were hospitalized for the first time. Compared to the non-hyperglycemic subgroup, patients in the hyperglycemic subgroup were found to have more extensive and significant demographic and clinical characteristics, higher levels of metabolism-related parameters, and more severe psychological and psycho-pathological symptoms. Age, thyroid stimulating hormone (TSH), triglycerides (TG) were risk factors for hyperglycemia in MDD patients, while course of disease was a protective factor.

Conclusion

The study findings suggest that the prevalence of hyperglycemia is not high in patients with MDD who are hospitalized for the first time. The risk variables for predicting hyperglycemia include age, TSH and TG. The above three factors and course of disease have good combined diagnostic ability for hyperglycemia.

Evaluation of Blood Pressure Status and Mortality in Turkey: Findings from Chronic Diseases and Risk Factors Cohort Study

Background and objectives: An important Non-Communicable Disease risk factor, hypertension (HT), is highly prevalent and controlled HT rates are not sufficient which increases the risk of developing premature deaths. The purpose of the study is to evaluate differences in all-cause and cardiovascular-related mortality according to HT status by using national data from Chronic Diseases and Risk Factors Survey in Turkey (2011-2017). Materials and Methods: Cox regression models were used to estimate hazard ratios (HR) for predicting the all-cause and cardiovascular system-related mortalities. Median follow-up period was 6.2 years. Results: Among individuals with HT, 41.8% was untreated, 30.1% received treatment and had controlled blood pressure, and 28.1% were under treatment but had uncontrolled BP levels. The hazard for mortality among treated & uncontrolled hypertensive participants was significantly higher for all-cause (HR = 1.32, 95% CI = 1.06-1.65), cardiovascular (HR = 2.11, 95% CI = 1.46-3.06), heart disease (HR = 2.24, 95% CI = 1.46-3.43), and Coronary Heart Disease mortality (HR = 2.66, 95% CI = 1.56-4.53) compared to normotensive participants. Conclusions: Individuals with HT who were treated but do not have controlled blood pressure in Turkey had a significantly increased risk of Cardiovascular Disease and all-cause mortality. Along with studies investigating the causes of uncontrolled blood pressure despite initiation of treatment, support should be provided to patients in cases of non-adherence to antihypertensive medication or life change recommendations.

Individualized Treatment for Glaucoma Patients with Diabetes mellitus

Glaucoma and diabetes mellitus are two common chronic diseases in Europe and worldwide which require intensive therapy. Various pathophysiological mechanisms have been discussed which favour the development of glaucoma, especially in the presence of diabetes mellitus. Medicinal and surgical adjustment of intraocular pressure is associated with some limitations in patients with diabetes mellitus, for example, filtering interventions show lower success rates than in non-diabetic glaucoma patients. Besides pure ophthalmological endocrinological therapy, the psychological burden of two chronic diseases should also be considered and included in the individual therapy plan.
