Discontinuation of blood pressure-lowering, glucose-lowering, and lipid-lowering medications after bariatric surgery in patients with morbid obesity: a nationwide cohort study in South Korea. Surg Obes Relat Dis 2024; 20:840-848. [PMID: 38631926 DOI: 10.1016/j.soard.2024.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 02/05/2024] [Accepted: 03/02/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND Limited evidence exists on the patterns of medication use for hypertension, diabetes mellitus (DM), and dyslipidemia after bariatric surgery among Asian patients. OBJECTIVES To investigate the patterns in the use of blood pressure-lowering, glucose-lowering, and lipid-lowering medications following BS in Korean patients with morbid obesity. SETTING This study is a retrospective cohort study using the Health Insurance Review and Assignment claims database of South Korea (from 2019 to 2021). METHODS We included patients who underwent BS between 2019 and 2020 in South Korea. We evaluated the treatment patterns of blood pressure-lowering, glucose-lowering, and lipid-lowering medications at 3-month intervals for 1-year following BS, including medication use, individual medication classes, and the number of medications prescribed. Furthermore, we estimated remission rates for each disorder based on patient characteristics by defining patients who discontinued their medications for at least 2 consecutive quarters as remission. RESULTS A total of 3810 patients were included in this study. For 1-year following BS, a marked decrease in the number of patients using blood pressure-lowering, glucose-lowering, and lipid-lowering medications was observed. The most remarkable decrease occurred in glucose-lowering medications, which decreased by approximately -75.1% compared with that at baseline. This tendency was consistently observed when analyzing both the number of medications prescribed and the specific medication classes. Regarding remission rates, patients who were female, younger, and received the biliopancreatic diversion-duodenal switch as their BS showed a relatively higher incidence of remission than other groups. CONCLUSIONS BS was associated with a decrease in the use of medications for hypertension, diabetes mellitus (DM), and dyslipidemia.

Abstract
Objective The aim of our study was to assess the prevalence and geographic variation of obesity-related hypertension in China among adults aged 45 years or older. Methods Data were derived from the China Health and Retirement Longitudinal Study (CHARLS) conducted in 2015. Stratified sample households covered 150 counties/districts and 450 villages/urban communities from 28 provinces by using household questionnaires, clinical measurements, and blood-based bioassays. A multivariable non-conditional logistic regression model was used to analyze the risk factors correlated with obesity-related hypertension. Results The prevalence of obesity-related hypertension was 22.7%, ~120 million people, among adults aged 45 years or older in China. For people in the age ranges of 45-54, 55-64, 65-74, and ≥75 years, the prevalence of obesity-related hypertension was 16.7, 24.3, 27, and 26.7%, respectively, and the prevalence of obesity-related hypertension among hypertensive participants was 66.0, 60.9, 54.2, and 47.3%, respectively. Compared with non-obesity-related hypertension, the obesity-related hypertensive patients had a higher prevalence of diabetes mellitus, dyslipidemia, and hyperuricemia (all P < 0.0001). The prevalence of obesity-related hypertension showed a decreasing gradient from north to south and from east to west. Multivariate logistic regression analysis showed that female gender, living in urban areas, diabetes mellitus, dyslipidemia, and hyperuricemia were positively correlated with obesity-related hypertension. Conclusion The prevalence of obesity-related hypertension among adults aged 45 years or older was high in China. Among hypertensive participants, older age was negatively correlated with obesity-related hypertension. Obesity-related hypertensive participants are more prone to aggregation of risk factors of atherosclerotic cardiovascular disease.

Abstract
Weight loss is an effective strategy for the management of hypertension, and bariatric surgery is the most effective weight loss and maintenance strategy for obesity. The importance of bariatric surgery in the long-term management of hypertension and which operation is most effective is less clear. We compared the effectiveness of vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) for remission and relapse of hypertension after surgery in the ENGAGE CVD cohort study (Effectiveness of Gastric Bypass Versus Gastric Sleeve for Cardiovascular Disease). Operations were done by 23 surgeons across 9 surgical practices. Hypertension remission and relapse were assessed in each year of follow-up beginning 30 days and up to 5 years postsurgery. We used a local instrumental variable approach to account for selection bias in the choice of VSG or RYGB. The study population included 4964 patients with hypertension at the time of surgery (n=3186 VSG and n=1778 RYGB). At 1 year, 27% of patients with RYGB and 28% of patients with VSG achieved remission. After 5 years, without accounting for relapse, 42% of RYGB and 43% of VSG patients had experienced hypertension remission. After accounting for relapse, only 17% of RYGB and 18% of VSG patients remained in remission 5 years after surgery. There were no statistically significant differences between VSG and RYGB for hypertension remission, relapse, or mean systolic and diastolic blood pressure at any time during follow-up.

Abstract
INTRODUCTION Obesity is accompanied by restriction in the quality of life and an increased risk of morbidity and mortality. Cardiovascular, orthopedic, and metabolic disorders are among the possible consequences. In the management of obesity, a combination therapy that includes dietary, exercise, and behaviour modules has proven its worth. AIM To evaluate the effect of weight-associated parameters, circulation associated parameters, glucose metabolism, body composition and life quality changes within a four-week inpatient rehabilitation program. MATERIALS AND METHODS Fifty-two patients underwent a 4-week inpatient rehabilitation program consisting of nutrition therapy, behavioural therapy and exercise therapy modules at the Eleonoren Clinic of Winterkasten, Germany. RESULTS The mean weight reduction of 52 obese patients 40 (76.9%) males, 12 (23.1%) females; mean age 46 years; mean Body Mass Index (BMI) 43,79 kg/m2) achieved was 7.1 kg (from 1.20 kg to 17.50 kg), and the BMI reduction was 2.3 kg/m2 (from 0.40 kg/m2 to 5.40 kg/m2). The excessive weight loss was highly significant (p<0.001). Weight reduction was accompanied by an improvement in the diabetic metabolic state (lowering of fasting blood-glucose 20 mg/dl, postprandial blood glucose 26 mg/dl, HbA1c 0.27%). In all 73% of the patients suffered from arterial hypertonia. The significant mean decline of systolic and diastolic blood pressure was 12.8 mmHg and 6.8 mmHg, respectively. The resting pulse was reduced by an average of 11 beats per minute. The Bioelectric Impedance Analysis (BIA) revealed a significant reduction of body fat content (p<0.001). The subjective impression of impaired life quality (SF-36 questionnaire) improved significantly. CONCLUSION The study clearly shows that the inpatient rehabilitation program at the Eleonoren Clinic was suitable to enhance the physical and mental state of people with obesity. In a two-year follow-up program the patients should take care of a permanent lifestyle change toward an improved dietary, movement and health behaviour.

The metabolic syndrome is a cluster of risk factors (central obesity, hyperglycaemia, dyslipidaemia and arterial hypertension), indicating an increased risk of diabetes, cardiovascular disease and premature mortality. The gastrointestinal tract is seldom discussed as an organ system of principal importance for metabolic diseases. The present overview connects various metabolic research lines into an integrative physiological context in which the gastrointestinal tract is included. Strong evidence for the involvement of the gut in the metabolic syndrome derives from the powerful effects of weight-reducing (bariatric) gastrointestinal surgery. In fact, gastrointestinal surgery is now recommended as a standard treatment option for type 2 diabetes in obesity. Several gut-related mechanisms that potentially contribute to the metabolic syndrome will be presented. Obesity can be caused by hampered release of satiety-signalling gut hormones, reduced meal-associated energy expenditure and microbiota-assisted harvest of energy from nondigestible food ingredients. Adiposity per se is a well-established risk factor for hyperglycaemia. In addition, a leaky gut mucosa can trigger systemic inflammation mediating peripheral insulin resistance that together with a blunted incretin response aggravates the hyperglycaemic state. The intestinal microbiota is strongly associated with obesity and the related metabolic disease states, although the mechanisms involved remain unclear. Enterorenal signalling has been suggested to be involved in the pathophysiology of hypertension and postprandial triglyceride-rich chylomicrons; in addition, intestinal cholesterol metabolism probably contributes to atherosclerosis. It is likely that in the future, the metabolic syndrome will be treated according to novel pharmacological principles interfering with gastrointestinal functionality.

Roux-en-Y gastric bypass alleviates hypertension and is associated with an increase in mid-regional pro-atrial natriuretic peptide in morbid obese patients. J Hypertens 2016; 33:1215-25.

Abstract
OBJECTIVE To examine 24-h blood pressure (24BP), systemic haemodynamics and the effect of sodium intake on 24BP in obese patients before and after gastric bypass surgery [laparoscopic Roux-en-Y gastric bypass (LRYGB)], and to determine whether weight loss from LRYGB might be related to an increase in plasma concentrations of atrial natriuretic peptide. METHODS Twelve hypertensive and 12 normotensive morbidly obese patients underwent LRYGB: 24BP, systemic haemodynamics and mid-regional pro-atrial natriuretic peptide (MRproANP) were assessed before, 6 weeks and 12 months after surgery. The effect of high versus low sodium intake on 24BP was evaluated before and 12 months after LRYGB. RESULTS Six weeks after LRYGB, the average weight loss was 20 kg, with a further 21 kg weight loss 1 year after surgery. In hypertensive patients, 24BP was significantly reduced at 6 weeks, but not 1 year after LRYGB. However, antihypertensive medications were successively reduced from baseline to 1 year after surgery. In normotensive patients, there was no change in 24BP 6 weeks after LRYGB, but a tendency towards a reduction 1 year after the operation. Plasma concentrations of MRproANP were subnormal prior to surgery in hypertensive patients and increased by 77% 1 year after the operation. In normotensive patients, preoperative concentrations were normal and increased only by 6%. High sodium intake induced plasma volume expansion, increased stroke volume and cardiac output, but no significant change in 24BP - neither before nor after LRYGB. CONCLUSIONS LRYGB resulted in a significant 24BP reduction and a substantial increase in MRproANP plasma concentrations in hypertensive, obese patients 6 weeks after surgery, suggesting a causal link between obesity-hypertension and altered release/degradation of cardiac natriuretic peptides.

LAP-BAND for BMI 30-40: 5-year health outcomes from the multicenter pivotal study. Int J Obes (Lond) 2015; 40:291-8. [PMID: 26283140 DOI: 10.1038/ijo.2015.156] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2015] [Revised: 06/28/2015] [Accepted: 06/28/2015] [Indexed: 12/20/2022]
Abstract
BACKGROUND We performed a 5-year multicenter study to evaluate the safety and effectiveness of the LAP-BAND System surgery (LBS) in patients with obesity with a body mass index (BMI) of 30-39.9 kg m(-)(2). This pivotal study was designed to support LBS application to the US Food and Drug Administration for broadening the indications for surgery and the lower BMI indication was approved with 1-year data in 2011, with the intention to complete the 5-year evaluation. OBJECTIVES To present broad health outcome data including weight change, patient reported outcomes, comorbidity change and complications during the 5-year study. SETTING The study was conducted at seven US private practice clinical trial sites. METHODS We enrolled 149 BMI 30-39.9 subjects into a 5-year, multicenter, longitudinal, prospective post-approval study. Data for those completing each time point are presented. RESULTS The predefined target of at least 30% excess weight loss was achieved by more than 76% of subjects by 1-year and at every year thereafter during the 5-year study. Mean percentage weight loss at 5 years was 15.9±12.4%. Sustained weight loss was accompanied by sustained improvement in generic and weight-specific quality of life, symptoms of depression and the prevalence of binge-eating disorder. The number of subjects with normal fasting triglyceride, high-density lipoprotein cholesterol, plasma glucose and HbA1c increased significantly between baseline and 5 years. Fifty-four months after LBS implantation, the rate of device explants without replacement was 5.4%; however, the rate of explants increased to 12.1% by month 60 owing to no cost-elective band removals offered to subjects at study exit. No deaths or unanticipated adverse device effects were reported. CONCLUSIONS The LBS is safe and effective for people with BMI 30-39.9 with demonstrated improvements in weight loss, comorbidities and quality of life, and with a low explant rate through 5 years following treatment.

Abstract
Metabolic syndrome is associated with adverse health outcomes and is a growing problem worldwide. Although efforts to harmonise the definition of metabolic syndrome have helped to better understand the prevalence and the adverse outcomes associated with the disorder on a global scale, the mechanisms underpinning the metabolic changes that define it are incompletely understood. Accumulating evidence from laboratory and human studies suggests that activation of the sympathetic nervous system has an important role in metabolic syndrome. Indeed, treatment strategies commonly recommended for patients with metabolic syndrome, such as diet and exercise to induce weight loss, are associated with sympathetic inhibition. Pharmacological and device-based approaches to target activation of the sympathetic nervous system directly are available and have provided evidence to support the important part played by sympathetic regulation, particularly for blood pressure and glucose control. Preliminary evidence is encouraging, but whether therapeutically targeting sympathetic overactivity could help to prevent metabolic syndrome and attenuate its adverse outcomes remains to be determined.

Abstract
The effectiveness of community-based participatory research (CBPR) efforts to address the disproportionate burden of hypertension among African Americans remains largely untested. The objective of this 6-month, noncontrolled, pre-/post-experimental intervention was to examine the effectiveness of a CBPR intervention in achieving improvements in blood pressure, anthropometric measures, biological measures, and diet. Conducted in 2010, this multicomponent lifestyle intervention included motivational enhancement, social support provided by peer coaches, pedometer diary self-monitoring, and monthly nutrition and physical activity education sessions. Of 269 enrolled participants, 94% were African American and 85% were female. Statistical analysis included generalized linear mixed models using maximum likelihood estimation. From baseline to 6 months, blood pressure decreased significantly: mean (± standard deviation) systolic blood pressure decreased from 126.0 ± 19.1 to 119.6 ± 15.8 mm Hg, P=0.0002; mean diastolic blood pressure decreased from 83.2 ± 12.3 to 78.6 ± 11.1 mm Hg, P<0.0001). Sugar intake also decreased significantly as compared with baseline (by approximately 3 tsp; P<0.0001). Time differences were not apparent for any other measures. Results from this study suggest that CBPR efforts are a viable and effective strategy for implementing nonpharmacologic, multicomponent, lifestyle interventions that can help address the persistent racial and ethnic disparities in hypertension treatment and control. Outcome findings help fill gaps in the literature for effectively translating lifestyle interventions to reach and engage African-American communities to reduce the burden of hypertension.

Abstract
BACKGROUND Hypertension and metabolic disorders, attended by impaired microcirculation, represent major risk factors for cerebrovascular impairment, as well as being individual components of the metabolic syndrome (MetS). Aim of the study was to establish whether mild hypertensives, aged ≤65years, may be affected by progressive microvascular damage impairing cerebrovascular perfusion, related to a progressive clustering of MetS components. METHODS Twenty-two normotensives with no MetS component (NTN-0), 29 hypertensives with no (HTN-0), 30 with one (HTN-1), 29 with two (HTN-2), 27 with three (HTN-3), 25 with all four (HTN-4) MetS components, were recruited. The study required office and twenty-four hour ambulatory blood pressure monitoring and video capillaroscopy. Functional (fCD), anatomical (aCD) and recruited (RECR) phalangeal skin capillarity were assessed. Cerebral vasodilatory reserve was measured by the breath-holding index (BHI), using transcranial Doppler, in HTN-1 and HTN-2 with MetS. RESULTS The fCD and aCD were reduced in hypertensives and progressively reduced in those with MetS, while RECR was also impaired. BHI was lower in HTN-2 than in HTN-1 (p<0.001). BHI was correlated with fCD in HTN-1 (.396, p: .046), HNT-2 (.497, p: .011), and with aCD in HTN-2 (.494, p: .012), by partial Pearson test. DISCUSSION The findings show that hypertensives exhibit an increasing microvascular rarefaction with MetS progression and that an impaired cerebral perfusion occurs when the MetS is established. The data underline the importance of preventing MetS in mild hypertensives, as it causes microvascular damage and impairs cerebral arterial perfusion.

Abstract
Obese patients are prone to arterial hypertension, require more antihypertensive medications, and have an increased risk of treatment-resistant arterial hypertension. Obesity-induced neurohumoral activation appears to be involved. The association between obesity and hypertension shows large inter-individual variability, likely through genetic mechanisms. Obesity affects overall cardiovascular and metabolic risk; yet, the relationship between obesity and cardiovascular risk is complex and not sufficiently addressed in clinical guidelines. The epidemiological observation that obesity may be protective in patients with established cardiovascular disease is difficult to translate into clinical experience and practice. Weight loss is often recommended as a means to lower blood pressure. However, current hypertension guidelines do not provide evidence-based guidance on how to institute weight loss. In fact, weight loss influences on blood pressure may be overestimated. Nevertheless, weight loss through bariatric surgery appears to decrease cardiovascular risk in severely obese patients. Eventually, most obese hypertensive patients will require antihypertensive medications. Data from large-scale studies with hard clinical endpoints on antihypertensive medications specifically addressing obese patients are lacking and the morbidity from the growing population of severely obese patients is poorly recognized or addressed. Because of their broad spectrum of beneficial effects, renin-angiotensin system inhibitors are considered to be the most appropriate drugs for antihypertensive treatment of obese patients. Most obese hypertensive patients require two or more antihypertensive drugs. Finally, how to combine weight loss strategies and antihypertensive treatment to achieve an optimal clinical outcome is unresolved.

Abstract
Obesity is a significant health problem worldwide and is associated with a number of co-morbidities including type 2 diabetes mellitus, hypertension, dyslipidemia, obstructive sleep apnea, and cardiovascular disease. A number of different pathophysiologic mechanisms including increased inflammation, oxidative stress, and insulin resistance have been associated with initiation and progression of atherosclerotic disease in obese individuals. Lifestyle modifications have provided modest results in weight reduction and the focus of interest has now shifted towards drug development to treat severely obese individuals with a body mass index (BMI) >30 kg/m(2) or those with a BMI >27 kg/m(2) who have additional co-morbidities. Different regimens focusing on dietary absorption or acting centrally to control hunger and food intake have been developed. However, their weight loss effect is, in most cases, modest and this effect is lost once the medication is discontinued. In addition, long-term use of these drugs is limited by significant side effects and lack of long-term safety and efficacy data. Orlistat is the only US FDA-approved medication for long-term use. A number of new medications are currently under investigation in phase III trials with promising preliminary results. This review comments on available anti-obesity pharmacologic regimens, their weight-loss benefit, and their impact on cardiovascular risk factors.

Abstract
BACKGROUND Even though patients with class 3 obesity (body mass index ≥ 40 kg/m(2)) are prone to arterial hypertension and respond less to antihypertensive drugs, they are not considered in hypertension treatment guidelines and data from prospective clinical trials are lacking. METHODS In a post hoc analysis of a clinical trial, we compared patients with class 3 obesity with patients with class 1/2 obesity. RESULTS AND CONCLUSIONS Blood pressure control in class 3 obesity was less likely to be achieved with hydrochlorothiazide monotherapy. While addition of amlodipine, irbesartan, or aliskiren to hydrochlorothiazide improved the blood pressure response, amlodipine was less effective and induced peripheral edema in 19% of patients with class 3 obesity.

Abstract
OBJECTIVE To investigate blood pressure (BP) in relation to changes in body mass index (BMI) in obese children during weight loss and subsequent weight regain. DESIGN A longitudinal study of obese boys and girls investigated through a 12-week weight loss intervention with follow-up investigations spanning 28 months. Results shown are from baseline; day 14, 33, and 82 during weight loss; and at months 10, 16 and 28 during follow-up. PATIENTS One hundred and fifteen obese children, 53 boys and 62 girls (8-15 years) with a median BMI standard deviation score (SDS) at baseline of 2.78 in boys, and 2.70 in girls. Ninety children completed the weight loss programme and 68 children entered the follow-up programme. METHODS Height, weight, systolic blood pressure (SBP), and diastolic BP (DBP) were recorded and analysed using a general linear mixed model. RESULTS Fifty-one percent of the obese children were pre or hypertensive at baseline. Both DBP and SBP declined significantly with weight loss, but a divergent response was found in the timing of the rebound in hypertension during the weight regain phase, that is DBP increased during weight regain, whereas SBP remained lower than baseline during 28 months of continuous weight regain. CONCLUSION The effect of weight reduction upon obesity-associated hypertension is noticeable and suggests the importance of an intensified childhood obesity treatment strategy in order to reduce the burden of future cardiovascular disease.

Abstract
BACKGROUND AND OBJECTIVE Patients with resistant hypertension (RH) are relatively frequently visited in specialized units of hypertension. The aim of this study was to assess the prevalence of target organ damage, central obesity and metabolic syndrome in a cohort of patients with RH consecutively included in the Register of Resistant Hypertension of the Spanish Society of Hypertension (SHE-LELHA). PATIENTS AND METHODS Cross-sectional, multicenter epidemiologic study in usual clinical practice conditions. Patients with clinical diagnosis of resistant hypertension, that is, office systolic and diastolic blood pressure ≥ 140 mm Hg and/or ≥ 90 mm Hg, respectively, despite a prescribed therapeutic schedule with an appropriate combination of three or more full-dose antihypertensive drugs, including a diuretic, were consecutively recruited from specialized hypertension units spread through Spain. Demographic and anthropometric characteristics as well as cardiovascular risk factors and associated conditions were recorded, and all the subjects underwent 24-h ambulatory blood pressure monitoring. Left ventricular hypertrophy was considered as a left ventricular mass index ≥ 125 g/m(2) in males and ≥ 110 g/m(2) in females. Left atrial enlargement was defined as an indexed left atrium diameter ≥ 26 mm/m(2). Microalbuminuria was defined as a urinary albumin/creatinine ratio ≥ 22 mg/g in males and ≥ 31 mg/g in females. RESULTS 513 patients were included, aged 64±11 years old, 47% women. Central obesity was present in 65.7% (CI 95% 61.6-69.9), 38.6% (CI 95% 34.4-42.8) had diabetes and 63.7% (CI 95% 59.4-67.9) had metabolic syndrome. The prevalence of left ventricular hypertrophy and left atrial enlargement, determined by echocardiography was 57.1% (CI 95% 50.8-63.5) and 10.0% (CI 95% 6.3-13.7) respectively. Microalbuminuria was found in 46.6% (CI 95% 41.4-51.8) of the subjects. Patients with metabolic syndrome were significantly older (65.4±11 and 62.5±12 years; P=.0052), presented a higher prevalence of diabetes (52.0% vs. 16.6; P<.0001) and were treated more frequently with ≥ 4 antihypertensive drugs (65.1 vs. 50.0%, P=.011). CONCLUSION The prevalence of central obesity, metabolic syndrome and target organ damage is very high in resistant hypertensive subjects.

Abstract
OBJECTIVE Metabolic syndrome (MetS) obesity is an independent risk factor for chronic kidney disease. This study was conducted to examine the effects of lifestyle interventions on renal parameters and putative metabolic, neuroadrenergic and hemodynamic mediators of renal injury. METHODS Untreated men and women (mean age 55 ± 1 years; BMI 32.7 ± 0.6 kg/m) without pre-existing renal dysfunction, who fulfilled MetS criteria were randomized to dietary weight loss (WL, n = 13), weight loss combined with aerobic exercise (WL + EX, n = 13), or no treatment (control, n = 12). Estimated glomerular filtration rate (eGFR), 24 h urinary albumin excretion, plasma renin activity (PRA), muscle sympathetic nerve activity (MSNA), baroreflex sensitivity (BRS), anthropometric, metabolic and fitness variables were measured at baseline and week 12. RESULTS Body weight decreased by -8.2 ± 0.8% in the WL and -10.7 ± 0.9% in the WL + EX groups (both P < 0.001). Fitness (maximal oxygen consumption) increased by 15 ± 5% and BRS by 5.5 ± 2.4 ms/mmHg in the WL + EX group only (P < 0.05). Serum creatinine decreased by -8.1 ± 4.8%, (WL, P = 0.016) and -14.9 ± 3.0% (WL + EX, P < 0.001). Estimated GFR increased commensurately but the increment was greater in the WL + EX group (P = 0.04). Albuminuria (P < 0.05) and MSNA (P < 0.001) decreased similarly in both groups, whereas PRA, high sensitivity C-reactive protein, uric acid and DBP decreased only in the WL + EX group (all P < 0.05). CONCLUSION Moderate weight loss in obese MetS patients is associated with a reduction in albuminuria and an improvement in eGFR which is augmented by exercise co-intervention.
