Albuminuria and other target organ damage in Chinese patients with hypertension and diabetes: A data analysis based on the ATTEND study

The Effect of TCM Syndrome Type and Western Medicine Detection on Patients with Hypertension and Diabetes Mellitus

Objective

To investigate the clinical changes of TCM syndrome type and microalbuminuria in patients with hypertension and diabetes mellitus.

Methods

A total of 442 patients with hypertension and diabetes who were admitted to our hospital from June 2016 to June 2021 were selected. All patients were divided into medication group and control group according to the random number method. Patients in the medication group were treated with conventional Western medicine-assisted traditional Chinese medicine, while patients in the control group were not treated with adjuvant medicine. The blood pressure and blood glucose of patients in the two groups were controlled within the normal range, and the clinical effects of the two groups were observed.

Results

The treatment of hypertension and diabetes in the two groups was diagnosed by the TCM syndrome type, and the cure rate was higher in the medication group. After 3 months, the glomerular filtration rate in the medication group increased steadily and the renal artery resistance index decreased, while the indexes in the control group had no significant change, with statistical significance (P < 0.05). After 6 months, the urinary albumin excretion rate and the ratio of urinary albumin to creatinine in the medication group were significantly decreased compared with those before medication, while there were no significant changes in the control group, with statistical significance (P < 0.05). The urine excretion rate of albumin in hypertensive patients with diabetes is higher, leading to the increased probability of microalbuminuria in patients, which is not only related to the course of hypertension and diabetes but also positively related to the course of hypertension and diabetes, smoking, drinking, and diet.

Conclusion

The combination of the TCM syndrome type and Western medicine detection method is more conducive to the two diagnosis and treatment methods that complement each other, improve each other, improve the effect of diagnosis and treatment, and are worthy of further research by researchers, so as to promote clinical application. Some other bad habits should also be corrected, such as smoking, drinking, and irregular diet, through adjusting the diet; control of high protein intake is also an important intervention measure for disease.

Why take organ damage in hypertension seriously?

The focus of recent European guidelines has been early initiation of antihypertensive therapy in risk groups, rapid achievement of target blood pressure with fixed combinations of antihypertensive drugs, and the best possible management of an individuals cardiovascular risk. Early intervention in the development of hypertension-mediated organ damage (HMOD) has been shown to have an effect on the subsequent reduction in the risk of cardiovascular events. The point of HMOD origination correlates with the magnitude and duration of blood pressure elevation, and there is no clearly defined boundary from which vascular damage begins to develop. A reduction in blood pressure with pharmacotherapy demonstrably decreases the risk of ischaemic heart disease, stroke, as well as the mortality rate (1). Large clinical trials have consistently shown a significant reduction in the risk of these complications with antihypertensive medications across the entire spectrum from mild to severe hypertension, including hypertension in the elderly as well as isolated systolic hypertension (2). Based on the latest knowledge, a reduction in blood pressure by a mere 5 mm Hg has a cardioprotective effect even in normotensive individuals, which fundamentally changes the view on the diagnosis and definition of hypertension as a disease (3).

The interaction on hypertension between family history and diabetes and other risk factors

To explore the individual effect and interaction of diabetes and family history and other risk factors on hypertension in Han in Shanghai China. The method of case–control study with l:l matched pairs was used, 342 cases of hypertension and 342 controls were selected and investigate their exposed factors with face-to-face. The method of epidemiology research was used to explore the individual effect and interaction of diabetes and family history and other risk factors on hypertension. The individual effect of family history (OR = 4.103, 95%CI 2.660–6.330), diabetes (OR = 4.219, 95%CI 2.926–6.083), personal taste (OR = 1.256, 95%CI 1.091–1.593), drinking behavior (OR = 1.391, 95%CI 1.010–1.914) and smoking behavior (OR = 1.057, 95%CI 1.00–1.117) were significant (p < 0.05). But individual effect of sex, education, occupation, work/life pressure, environmental noise, sleeping time and sports habit were not significant (p > 0.05). The OR of interaction between FH and DM to hypertension was 16.537 (95%CI 10.070–21.157), between FH and drinking behavior was 4.0 (95%CI 2.461–6.502), FH and sport habit was 7.668 (95%CI 3.598–16.344), FH and personal taste was 6.521 (95%CI 3.858–11.024), FH and smoking behavior was 5.526 (95%CI 3.404–8.972), FH and work/life pressure was 4.087 (95%CI 2.144–7.788). The SI of FH and DM was 2.27, RERI was 8.68, AP was 52.48% and PAP was 55.86%. FH and DM, personal taste, smoking behavior had positive interaction on hypertension, but FH and sport habits, drinking behavior, work/life pressure had reverse interaction on hypertension. FH and diabetes were very important risk factors with significant effect for hypertension. FH and diabetes, personal taste, smoking behavior had positive interaction on hypertension, but FH and sport habits, drinking behavior, work/life pressure had reverse interaction on hypertension.

Renal Effects of Sulodexide in Type 2 Diabetic Patients without Nephrotic Range Proteinuria

BACKGROUND

Glycosaminoglycan plays an important role in the maintenance of glomerular charge selectivity of diabetic nephropathy. Sulodexide, a mixture of naturally occurring glycosaminoglycan polysaccharide components, has shown a nephroprotective effect in an experimental model of diabetic nephropathy. Although sulodexide reduced albuminuria in patients with type 1 and type 2 diabetes, long-term effects in patients with type 2 diabetes with significant proteinuria have not been established.

OBJECTIVES

The study was aimed at investigating the effects of sulodexide on proteinuria and renal function in patients with type 2 diabetes and nephropathy.

METHODS

Fifty-two patients with proteinuria between 500 and 3000 mg/day received sulodexide 200 mg/day for 12 months, while 56 matched patients with type 2 diabetes constituted the control group. All patients received standard metabolic and blood pressure controls. Primary outcome was evaluated as percentage of reduced proteinuria compared with the control group. Renal function was assessed using estimated glomerular filtration rate (GFR).

RESULTS

Proteinuria significantly increased in the control group [0.9 (IQR 0.3 to 1.78) to 1.16 (IQR 0.44 to 2.23) g/gCr, P = 0.001], whereas it remained stable in the sulodexide group [0.66 (IQR 0.23 to 0.67) to 0.67 (IQR 0.17 to 1.51) g/gCr, P = 0.108]. At 12 months, proteinuria was higher by 19.4% (IQR 10.3 to 37.6) in the control group while proteinuria was lower by -17.7% (IQR -53.1 to 3.2) in the sulodexide group with a significant difference between groups (P = 0.001). Renal function was noted as a change of estimated GFR, and serum creatinine decreased significantly during the study in both groups but did not significantly differ between groups. No significant changes in the blood pressure, fasting plasma glucose, and hemoglobin A1C were reported.

CONCLUSION

In addition to standard treatment, sulodexide is efficient in maintaining proteinuria in patients with type 2 diabetes with nonnephrotic range proteinuria, but it did not provide an additional benefit concerning renal disease progression.
