PAIT-survey-Prevalence of albuminuria in patients with diabetes and hypertension in Turkey

Microalbuminuria and Hypertension among Immigrants with Type 2 Diabetes: A Community-Based Cross-Sectional Study

PURPOSE

This study examined the association of microalbuminuria (MAU), as determined by albumin-to-creatinine ratio (ACR), with hypertension (HTN) among Turkish immigrants with type 2 diabetes (T2D) living in deprived neighborhoods of The Hague, Netherlands.

METHODS

A total of 110 participants, physician-diagnosed with T2D, aged ≥ 30 years were recruited from multiple sources from The Hague, Netherlands in a cross-sectional design. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured using automated office blood pressure equipment. Urine albumin was measured by immunoturbidimetric assay. Urine creatinine was determined using the Jaffe method. MAU was defined as ACR ≥ 3.5 mg/mmol for females and/or ACR ≥ 2.5 mg/mmol for males.

RESULTS

MAU was present in 21% of Turkish immigrants with T2D. Adjusted logistic regression analysis indicated that the odds of having MAU were 6.6 times higher in hypertensive than those that were normotensive (p = 0.007; 95% confidence interval [CI]: 1.19, 36.4).

CONCLUSION

These findings suggest that HTN and MAU may be assessed as a standard of care for T2D management for this population. Prospective studies of diabetes outcomes are recommended to further verify these findings.

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.

Blood pressure and glucose control and the prevalence of albuminuria and left ventricular hypertrophy in patients with hypertension and diabetes

We investigated association between blood pressure and glucose control and the prevalence of albuminuria and left ventricular hypertrophy (LVH) in patients with hypertension and diabetes. Our study participants were treated patients with both diseases, enrolled in a China nationwide registry. The 773 patients were classified into four groups according to the control status of hypertension (systolic/diastolic blood pressure [BP] ≤140/90 mm Hg) and diabetes (HbA1c <7.0%): both uncontrolled (n = 208), only diabetes (n = 175) or hypertension controlled (n = 172), and both controlled (n = 218). Albuminuria was defined as a urinary albumin-to-creatinine ratio of ≥30 mg/g. LVH was assessed by the electrocardiogram Cornell product method. Antihypertensive therapy was not different between the four groups (P ≥ .48). The use of insulin alone or insulin plus oral antidiabetic agents was significantly higher than those with both diseases controlled (P ≤ .02). Patients with controlled hypertension and diabetes had a significantly (P < .0001) lower prevalence of albuminuria (odds ratio 0.22, 95% confidence interval 0.11-0.43) than those with both diseases uncontrolled. Intensive BP control to <130/80 mm Hg was associated with lower risks of albuminuria in all patients (P = .001) and patients with HbA1c <7.0% (P = .048). Intensive glycemic control to HbA1c <6.5% was also associated with a significantly lower risk of albuminuria in all patients (P = .01), but not those with controlled BP (P = .43). Similar trends were observed for LVH, but statistical significance was not achieved on either intensive control condition (P ≥ .07). In patients with hypertension and diabetes, blood pressure and glucose control were associated with a lower prevalence of albuminuria and LVH, especially when achieving a more stringent target.

PAIT-Survey Follow-Up: Changes in Albuminuria in Hypertensive Diabetic Patients with Mild-Moderate Chronic Kidney Disease

INTRODUCTION

Albuminuria is an early marker of kidney disease and reduction of albuminuria translates into a decreased occurrence of cardiovascular and renal outcomes.

AIMS

To evaluate the changes in the prevalence of albuminuria in diabetic hypertensive patients treated with several combinations of renin-angiotensin aldosterone system with calcium channel blockers.

METHODS

We analysed data from 668 unselected patients from the PAIT survey (mean age 60.4 ± 10.2 years, prevalence of males 38%), with and without albuminuria, maintained for 6 months with the previous treatment with amlodipine-valsartan, amlodipine perindopril, lercanidipine-enalapril, verapamil-trandolapril, nitrendipine-enalapril and felodipine-ramipril Albuminuria was assessed, as urinary albumin-creatinine ratio, using a Multistic-Clinitek device analyzer. Microalbuminuria was defined as a loss of 3.4-33.9 mg albumin/mmol creatinine (30-300 mg/g) and macroalbuminuria as a loss of > 33.9 mg albumin/mmol creatinine (> 300 mg/g). Blood pressure was measured with a validated digital device.

RESULTS

At baseline, albuminuria was present in 310 subjects (46.4%) (microalbuminuria in 263 (84.8%), macroalbuminuria in 15.2%), and normoalbuminuria in 53.6% 358. After 6 months, the prevalence of subjects with albuminuria was significantly lowered (p < 0.01) by 23.5% (microalbuminuria - 23.9%, p < 0.01 and macroalbuminuria - 21.3%). The prevalence of subjects with microalbuminuria was reduced with all treatments: amlodipine-valsartan - 15.6%, amlodipine-perindopril - 11.8%, lercanidipine-enalapril - 41.3% and verapamil-trandolapril - 19.2%. Data with nitrendipine-enalapril and felodipine-ramipril were not analyzed, due to the low number of patients. The frequency of patients with normoalbuminuria was significantly higher (p < 0.01) with lercanidipine-enalapril compared with any other treatment. Blood pressure was significantly (p < 0.01) reduced, with a similar effect between treatments.

CONCLUSIONS

The treatments decrease the prevalence of subjects with albuminuria, showing a significant difference among the different drug combinations, favoring the use of new dihydropyridine calcium channel blockers, such as lercanidipine, combined with RAAS inhibitors, to control albuminuria in diabetic hypertensive patients.
