A number of factors like sedentary lifestyle, unhealthy diet and stress are driving a significant and rapid increase in non-communicable diseases (NCD) like hypertension and diabetes cases in India, doctors said on Friday.

According to an alarming new study led by the Indian Council of Medical Research (ICMR) and published in the journal ‘The Lancet Diabetes and Endocrinology’, India is home to a whopping 31 core people with hypertension and 10 crore with diabetes.

The study also showed that 13 core Indians are pre-diabetic, 21 crore people live with high cholesterol, 18 crore suffer from high LDL cholesterol or bad cholesterol, 25 core lives with generalised obesity, and 35 crore have abdominal obesity.

These non-communicable diseases were also behind 65 per cent of deaths in India and 40 per cent of hospitalisation, a study by Apollo Hospitals revealed in April.

Speaking to IANS, Rakesh Gupta, Senior Consultant, Internal Medicine, Indraprastha Apollo Hospitals, Delhi, said the increasing prevalence can be attributed to several factors.

“Rapid urbanisation and the adoption of a more Westernised lifestyle have led to a decline in physical activity levels. Sedentary behaviours such as prolonged sitting and reduced exercise contribute to weight gain and increase the risk of hypertension and high cholesterol. Additionally, increased stress levels and lack of proper sleep can also impact blood pressure and cholesterol levels negatively,” Gupta said.

He also blamed significant changes in dietary habits from traditional Indian diets, consisting typically of whole grains, fruits, vegetables and legumes, to more processed and high-calorie foods.

“The consumption of unhealthy fats, refined carbohydrates, and excessive salt has increased, leading to weight gain, high blood pressure, and elevated cholesterol levels,” the expert noted.

There is also a genetic predisposition among Indians, particularly those of South Asian descent, to develop hypertension and dyslipidemia. Evidence also indicates that Indians are more susceptible to insulin resistance.

Certain gene variants, when combined with unhealthy lifestyle factors, increase the risk further, the doctor explained.

Increased consumption of sugar, found in many ultra-processed foods, has been linked to overweight and obesity, which affects nearly 40 per cent of the global population, including crores of children.

“It is imperative to recognise the intricate relationship between sugar consumption and the development of diabetes. Sugar, once regarded as a simple pleasure, can disrupt the delicate balance of our body’s glucose regulation, predisposing individuals to this chronic condition,” Manoj Vithlani, Senior Consultant physician and diabetologist, HCG Hospitals, Ahmedabad, told IANS.

A commonly used low or no-calorie alternative to sugar, known as non-sugar sweeteners (NSS), is also harmful to health in the long run, the expert said.

NSS is generally marketed as aiding weight loss or maintenance of healthy weight and is frequently recommended as a means of controlling blood glucose in individuals with diabetes.

“Higher intake of NSS is associated with increased risk of Type-2 diabetes, cardiovascular diseases and related mortality, and all-cause mortality,” said Anurag Aggarwal, Consultant-Internal Medicine, Fortis Escorts Hospital, Faridabad.

It is also associated with a higher body mass index and increased risk of incident obesity, and the risk of bladder cancer.

The health experts stressed the need to educate people to make informed choices, embrace a balanced approach to nutrition and adopt healthier alternatives. This includes engaging in regular physical activity such as walking, jogging, or cycling and reducing sedentary time.

A balanced diet that includes fruits, vegetables, whole grains, lean proteins, and healthy fats should be followed while limiting the intake of processed foods, saturated fats, trans fats, and sugary beverages.

The doctors also recommended weight and stress management as well as regular health check-ups to keep a check on blood pressure, cholesterol levels and diabetes.

HARRISBURG – Capital Blue Cross members are effectively fighting back against diabetes using the insurer’s free and convenient programs that have helped them lose weight, lower their blood sugar levels, reduce their medications, and collectively save nearly $6 million in healthcare costs.

In 2021, Capital became the first Pennsylvania health insurer to offer a unique program that works to reverse the effects of type 2 diabetes. Capital also began offering a separate program that helps members reduce their risk of developing type 2 diabetes, and helps those with types 1 or 2 manage their disease.

Preliminary results show Capital’s efforts to fight the diabetes epidemic are paying off:

  • Capital members using the diabetes control program collectively lost more than 26,000 pounds in 2022.
  • Capital members using the diabetes reversal program saw their A1c levels drop by more than a full point on average in just the first 90 days. Higher A1c levels are linked to diabetes complications.
  • On average, Capital members also were able to reduce prescription medications by about 45% in the first 90 days of using the diabetes reversal strategy.
  • Combined, the diabetes control programs already have helped Capital customers save nearly $6 million collectively, and an average engaged member can save $1,800 to $2,000 annually.

About one-third of Americans will develop diabetes sometime in their lifetime. This chronic disease can cause severe health problems, damage vital organs, and shorten life expectancy. The harm diabetes does to America’s collective health is matched by the financial toll it takes. The disease costs the U.S. nearly $330 billion a year, including $90 billion in lost productivity in the workplace.

In addition to these programs, Capital Blue Cross offers a broad range of proven resources and support to help get diabetes under control and encourage healthier lifestyle choices that can prevent Type 2 diabetes.

Capital reaches out to high-risk members with diabetes to provide care management opportunities and offers multiple programs to employer groups, including a diabetes presentation, an awareness toolkit, and Take Charge – a virtual, self-paced course that helps participants develop lifestyle habits to help control diabetes.

For those who want a more personalized experience, Capital offers one-on-one consultations at any of our five Capital Blue Cross Connect health and wellness centers.

Statin initiation and risk of incident kidney disease in patients with diabetes

Diabetes News


Abstract

Background: The role of statin therapy in the development of kidney disease in patients with type 2 diabetes mellitus (DM) remains uncertain. We aimed to determine the relationships between statin initiation and kidney outcomes in patients with type 2 DM.

Methods: Through a new-user design, we conducted a multicentre retrospective cohort study using the China Renal Data System database (which includes inpatient and outpatient data from 19 urban academic centres across China). We included patients with type 2 DM who were aged 40 years or older and admitted to hospital between Jan. 1, 2000, and May 26, 2021, and excluded those with pre-existing chronic kidney disease and those who were already on statins or without follow-up at an affiliated outpatient clinic within 90 days after discharge. The primary exposure was initiation of a statin. The primary outcome was the development of diabetic kidney disease (DKD), defined as a composite of the occurrence of kidney dysfunction (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73 m2 and > 25% decline from baseline) and proteinuria (a urinary albumin-to-creatinine ratio ≥ 30 mg/g and > 50% increase from baseline), sustained for at least 90 days; secondary outcomes included development of kidney function decline (a sustained > 40% decline in eGFR). We used Cox proportional hazards regression to evaluate the relationships between statin initiation and kidney outcomes, as well as to conduct subgroup analyses according to patient characteristics, presence or absence of dyslipidemia, and pattern of dyslipidemia. For statin initiators, we explored the association between different levels of lipid control and outcomes. We conducted analyses using propensity overlap weighting to balance the participant characteristics.

Results: Among 7272 statin initiators and 12 586 noninitiators in the weighted cohort, statin initiation was associated with lower risks of incident DKD (hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.62–0.83) and kidney function decline (HR 0.60, 95% CI 0.44–0.81). We obtained similar results to the primary analyses for participants with differing patterns of dyslipidemia, those prescribed different statins, and after stratification according to participant characteristics. Among statin initiators, those with intensive control of high-density lipoprotein cholesterol (LDL-C) (< 1.8 mmol/L) had a lower risk of incident DKD (HR 0.51, 95% CI 0.32–0.81) than those with inadequate lipid control (LDL-C ≥ 3.4 mmol/L).

Interpretation: For patients with type 2 DM admitted to and followed up in academic centres, statin initiation was associated with a lower risk of kidney disease development, particularly in those with intensive control of LDL-C. These findings suggest that statin initiation may be an effective and reasonable approach for preventing kidney disease in patients with type 2 DM.

Statins are among the most commonly prescribed medications, administered to 146 million people worldwide.1 Statin therapy reduces the risk of cardiovascular disease in patients with type 2 diabetes mellitus (DM) and in patients with hypertension. 2–5 Current guidelines from the Canadian Cardiovascular Society and the American Diabetes Association recommend statin therapy for patients with diabetes aged 40 years or older.6–9 However, some recent studies have shown that treatment with a statin alters glucose metabolism and affects glycemic control in such patients.10–15 Given that a worsening of glycemic control is associated with the development or progression of microvascular disease,16 patients with diabetes who are undergoing statin treatment might be at higher risk of developing microvascular complications.

Diabetic kidney disease (DKD) is a common microvascular complication in patients with type 2 DM, is the leading cause of end-stage kidney disease, and imposes enormous health care and financial burdens in both low- and high-income countries.17,18 Although multiple experimental and epidemiologic studies have shown that dyslipidemia is a risk factor for kidney disease in patients with diabetes, the role of lipid-lowering therapy in the development of kidney disease in patients with type 2 DM remains unclear.19–21 Previous studies suggested that statins might have protective effects against diabetes-induced oxidative stress and podocyte injury in the kidney. 22,23 However, several population-based studies have shown that the use of statins does not reduce the risk of kidney disease24,25 and, as noted earlier, may even have adverse effects in patients with diabetes.26,27 Thus, it is uncertain whether the administration of statins represents an appropriate means of preventing DKD.

To address this knowledge gap, we performed a retrospective observational cohort study of patients with type 2 DM across China to determine the effect of statin initiation on the development of DKD and kidney function decline.

Methods

Study design and setting

This is a multicentre retrospective cohort study using a new-user design and de-identified data collected from the China Renal Data System (CRDS) database from Jan. 1, 2000, to May 26, 2021.28 At present, the government’s basic medical insurance provides coverage for more than 95% of the population in China, including access to care at academic health care centres.29

We reported the study according to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline.30

Data source

The CRDS database is a joint initiative of the National Clinical Research Center for Kidney Disease and the China Center for Disease Control and Prevention. This database contains data for more than 7 million inpatients and outpatients from 19 large, urban academic centres that cover the major geographic regions across China (Appendix 1, Supplementary Methods 1, available at www.cmaj.ca/lookup/doi/10.1503/cmaj.230093/tab-related-content). The accuracy and completeness of this database have been verified in our previous studies31,32 and by other validation activities (Appendix 1, Supplementary Methods 1).

Participants

We selected patients with type 2 DM admitted to hospital between Jan. 1, 2000, and May 26, 2021, and aged 40 years or older, for inclusion in the present study. The diagnosis of type 2 DM was based on the International Classification of Diseases, 10th Revision (ICD-10) code E11,33 and all hospital admissions for diabetes-related complications or general admissions with diabetes as a comorbidity were included.

We assigned the date of the first statin prescription as the index date for statin initiators. For noninitiators, we assigned the index date as a randomly selected date of any admission (i.e., not limited to hospital admissions for diabetes or related complications). All study participants (both initiators and noninitiators) had not received a statin prescription within the previous year before the index date.

We excluded patients for whom baseline serum creatinine or urinary protein concentrations were not available, and those with a diagnosis of chronic kidney disease (as defined by ICD-10 code N18) or an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73 m2 or proteinuria (defined as a urinary albumin-to-creatinine ratio ≥ 30 mg/g) before the index date.34 We also excluded patients with identified or suspected acute kidney injury at the index date. We based the diagnosis of acute kidney injury on ICD-10 codes N10/N17/O90.4 or Kidney Disease Improving Global Outcomes creatinine criteria.35 We defined suspected acute kidney injury as a 50% or greater change in serum creatinine within 1 month.36

We defined a 1-year observational period before the index date and excluded those who did not have any records of prescriptions from an affiliated outpatient clinic or during a hospital admission during this period. We also excluded patients without follow-up at an affiliated outpatient clinic within 90 days after discharge or who were prescribed a statin and 1 or more other lipid-lowering drugs. The follow-up period started on the index date and continued until any outcome occurred, the participant was lost to follow-up, or the date of the final serum creatinine measurement or urinary protein test, whichever came first.

Exposure

The primary exposure was the initiation of statin treatment (Appendix 1, Supplementary Methods 2), as defined by a statin being prescribed. We extracted details of statin prescriptions — including dose, usage, and starting and ending times of statins during inpatient and outpatient periods — from the CRDS database and further validated them by accessing the relevant individual academic centre’s information system to extract the electronic medical records data. For comparison, we defined noninitiators as those who did not receive a statin prescription or a prescription for any nonstatin lipid-lowering drugs (e.g., fibrate, ezetimibe and nicotine acid).

Outcomes

The primary outcome was the development of DKD, defined as a composite of the occurrence of kidney dysfunction37 (defined as an eGFR < 60 mL/min/1.73 m2 and > 25% decline from baseline) and proteinuria (defined as a urinary albumin-to-creatinine ratio ≥ 30 mg/g and > 50% increase from baseline), sustained for at least 90 days. The secondary outcomes were individual indices indicating the development of DKD and the development of kidney function decline (defined as a sustained > 40% decline in eGFR).38 We calculated the eGFR using serum creatinine and the Chronic Kidney Disease Epidemiology Collaboration equation.39

Covariates

We collected demographic information (age, sex) and comorbidities determined using ICD-10 codes at baseline (defined as within a 3-month period before the index date). We calculated the age-adjusted Charlson Comorbidity Index to quantify the overall comorbidity status.40 We identified antihypertensive drugs and glucose-lowering drugs during the observational period (i.e., within 1 year before the index date). The relevant Anatomic Therapeutic Chemical codes are summarized in Appendix 1, Supplementary Table 1.

We extracted physical examination and laboratory test results, including blood pressure measurement, body mass index, serum lipid concentrations (total cholesterol [TC], low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C] and triglyceride [TG]), eGFR, glycosylated hemoglobin (HbA1c), serum uric acid, alanine aminotransaminase and aspartate aminotransaminase, hemoglobin and leukocytes. We included the most recent measurements of these parameters within 3 months before the index date. All covariates were considered clinically relevant based on biological mechanism or evidence from previously published data.10,41

Statistical analysis

We summarized the clinical parameters and baseline characteristics of the statin initiator and noninitiator groups and used standardized mean differences (SMDs) to evaluate the balance of the 2 groups.

We used propensity score overlap weighting to balance the characteristics of the statin initiators and noninitiators to mimic randomized clinical trials.42 We identified a total of 38 covariates and modelled their hypothetical causal pathways using a directed acyclic graph (Appendix 1, Supplementary Figure 1); we included these in the propensity score overlap weighting. Overlap weight for each participant was calculated by multivariable logistic regression and assigned to each participant proportionally to the probability of that patient belonging to the opposite treatment group. This method created balance between the exposure groups with regard to all the covariates included in the propensity score. After weighting, parameters with an SMD higher than 0.1 were regarded as unbalanced between the groups.43

We evaluated the relationships between statin initiation and kidney outcomes using Cox proportional hazards regression after weighting. Hazard ratios (HRs) and the corresponding 95% confidence intervals (CIs) were reported. We tested the proportional hazards assumption using Schoenfeld residuals.

We conducted a predefined subgroup analysis according to the presence or absence of dyslipidemia (defined as LDL-C ≥ 3.4 mmol/L or TC ≥ 5.2 mmol/L or TG ≥ 1.7 mmol/L) and the pattern of dyslipidemia (high TC or LDL-C, high TG, or both).44 We also determined the potential effect modification associated with statin initiation on the development of DKD using the same Cox model after weighting and after stratification according to age, sex, HbA1c, comorbidity, use of insulin, use of metformin, and treatment with antihypertensive drugs (renin–angiotensin system inhibitors, β-blockers, calcium channel blockers and diuretics).

Additional analyses

We performed additional analyses to compare the effects of statin initiation on kidney outcomes in patients with different levels of lipid control. We evaluated the first serum LDL-C concentration recorded for statin initiators between 90 and 365 days after the index date. Those whose serum LDL-C concentrations were less than 1.8 mmol/L, 1.8 to less than 3.4 mmol/L, and 3.4 mmol/L or higher were defined as belonging to the intensive lipid control, moderate lipid control and inadequate lipid control groups, respectively.44,45 Furthermore, we evaluated the relationships between the various types of statins with kidney outcomes. We also conducted a multivariable logistic regression to assess the association between statin initiation and the use of glucose-lowering drugs during follow-up, after weighting.

Sensitivity analyses

We performed a series of sensitivity analyses to evaluate the robustness of the findings. We developed a long-term follow-up cohort from our study population, which excluded those with loss of follow-up (i.e., not seen at an affiliated outpatient clinic) within the first 3 years. We fitted propensity score matching and inverse probability treatment weighting (stable weighting) models to evaluate the relationship between statin initiation and kidney outcomes, in place of overlap weighting (Appendix 1, Supplementary Methods 3). We used a time-varying Cox model with statin initiation treated as a time-varying exposure. To evaluate the bias associated with reverse causality, we excluded participants who developed a kidney outcome within the first year of the study.

Finally, to account for the bias introduced by unmeasured confounders, we calculated the E-value for the kidney outcomes. The E-value represents the minimum magnitude of association required for an unmeasured confounder to reverse the observed association toward a null. In brief, if the relative risk between unmeasured confounders, kidney outcomes and statin initiation is greater than the estimated E-value, residual confounders may be sufficient to explain the identified association.46

We managed missing data in all analyses using multiple imputation, with an assumption of missing at random. We performed all statistical analyses using SAS version 9.4 (SAS Institute, Cary, NY, USA) and R 4.1.1 (R Foundation for Statistical Computing, Vienna, Austria) and with a significance level of 0.05 (2-sided).

Ethics approval

The study was approved by the China Office of Human Genetic Resources for Data Preservation Application (approval no.: 2021-BC0037). The protocol was approved by the Medical Ethics Committee of Nanfang Hospital, Southern Medical University (approval no.: NFEC-2019–213), and the requirement for informed consent was waived.

Results

We selected a total of 19 858 participants from the original cohort of 455 493 patients with type 2 DM admitted to a participating hospital during the study period (Figure 1). The baseline characteristics and weighting of the groups are summarized in Table 1 and Appendix 1, Supplementary Table 2. Among 7272 statin initiators and 12 586 noninitiators, 11 012 (55.5%) were male and their median age was 62.2 years (interquartile range 54.5–69.4 yr). The mean duration of follow-up was 1.6 years.

Association of statin initiation with risk of kidney outcomes

The weighted cumulative incidences of kidney outcomes among statin initiators and noninitiators are shown in Figure 2 and Appendix 1, Supplementary Table 3. Statin initiation was significantly associated with lower cumulative incidences of incident DKD, new-onset proteinuria and more than 40% decline in eGFR (p < 0.05 for all), but not with new-onset eGFR lower than 60 mL/min/1.73 m2 (p = 0.34). After weighting, the risk of incident DKD was significantly lower for statin initiators than for noninitiators (HR 0.72, 95% CI 0.62–0.83) (Figure 3).

Adjusted hazard ratio (HR) of statin initiation associated with kidney outcomes among all patients and patients with or without dyslipidemia. We defined dyslipidemia as low-density lipoprotein cholesterol (LDL-C) ≥ 3.4 mmol/L or total cholesterol (TC) ≥ 5.2 mmol/L or triglyceride (TG) ≥ 1.7 mmol/L.44 We estimated HRs by Cox proportional model after propensity score overlap weighting with confounders adjusted for all characteristics in Table 1. Schoenfeld residuals validated the proportional hazards assumption (p = 0.35). Note: CI = confidence interval, DKD = diabetic kidney disease, eGFR = estimated glomerular filtration rate.

Using Cox proportional hazards regression after weighting, statin initiation was found to be associated with lower risks of new-onset eGFR lower than 60 mL/min/1.73 m2 (HR 0.63, 95% CI 0.50–0.79), new-onset proteinuria (HR 0.70, 95% CI 0.59–0.84) and kidney function decline (HR 0.60, 95% CI 0.44–0.81) (Figure 3).

In subgroup analyses, we also obtained consistent findings for participants with or without dyslipidemia and with different patterns of dyslipidemia (high TG, high TC or LDL-C, or both) (Figure 3 and Appendix 1, Supplementary Figure 2). We did not find any significant effect modifiers among the other clinical characteristics (all pinteraction > 0.05) (Appendix 1, Supplementary Figure 3).

Additional analyses

We performed additional analyses to compare the effects of statin initiation on kidney outcomes in those with different levels of LDL-C control (Appendix 1, Supplementary Figure 4). By comparison with the inadequate lipid control group (LDL-C ≥ 3.4 mmol/L), patients with intensive control (LDL-C < 1.8 mmol/L) had the lowest risk of developing DKD (HR 0.51, 95% CI 0.32–0.81). Similar results were obtained for the risk of new-onset eGFR lower than 60 mL/min/1.73 m2 and proteinuria. Among those with moderate control (LDL-C 1.8 to < 3.4 mmol/L), there was no significant association with the development of DKD when compared with the inadequate lipid control group (HR 0.84, 95% CI 0.61–1.11).

Atorvastatin (n = 4424 [60.8%]) and rosuvastatin (n = 1135 [15.6%]) were the most frequently used statins (Appendix 1, Supplementary Table 4). The hazard ratios for DKD ranged from 0.65 to 0.88 and from 0.46 to 0.75 for patients taking lipophilic (simvastatin, pitavastatin, fluvastatin and atorvastatin) and hydrophilic (pravastatin and rosuvastatin) statins, respectively.

With respect to glucose metabolism and glycemic control (Appendix 1, Supplementary Table 5), there was a significant positive association between statin initiation and an increase in the use of oral glucose-lowering drugs (OR 1.75, 95% CI 1.50–2.05).

Sensitivity analyses

About 1 in 5 study participants (4107/19 858, 20.7%) were followed up for longer than 3 years, with a mean follow-up of 3.5 years. The associations of statin initiation with kidney outcomes remained in these patients (Appendix 1, Supplementary Table 6). We also found similar results for the associations of statin initiation with the risks of kidney outcomes when using the stable weighting, propensity score matching and time-varying Cox models (Appendix 1, Supplementary Table 7 and 8).

With respect to the reverse causality (Appendix 1, Supplementary Table 9), we found consistent results after excluding participants who developed DKD within 1 year. The E-value for kidney outcomes ranged from 2.1 to 2.7 in the primary analyses.

Interpretation

In this multicentre cohort study of patients with type 2 DM admitted to and followed up in an academic centre in China, we found that statin initiation was associated with significantly lower risks of developing DKD and kidney function decline. These associations were robust, being unaffected by differences in clinical characteristics or the pattern of dyslipidemia. The similar results in multiple sensitivity analyses that evaluated reverse causality and unmeasured confounders also suggest that the findings of the present study are robust.

Several animal and epidemiologic studies have shown that dyslipidemia plays a role in the development and progression of DKD.47,48 Because dyslipidemia is both a risk factor and potential target for the treatment of DKD, further research into the clinical benefits of lipid-lowering drugs is required. However, given that the cardiovascular benefits of statins in patients with diabetes have been well established,2,49 it is difficult to conduct a randomized controlled trial (RCT) to compare the kidney outcomes of patients undergoing statin therapy with placebo-treated controls. Therefore, the use of medical data obtained from real-world clinical practice represents a rational means of studying the effect of statins to prevent kidney disease in patients with diabetes. Our findings provide evidence that statins may be reno-protective in patients with type 2 DM in a real-world setting and may help physicians to optimize disease management.

The results of previous studies assessing the reno-protective effect of statins in patients with diabetes have been contradictory. Two large population-based studies (n = 43 438 and 62 716)24,27 showed that statin use did not have beneficial effects on kidney outcomes and may possibly have had adverse effects. However, the kidney outcomes used in these studies were based on ICD codes, which lack sensitivity, and therefore the incidence of the outcomes may have been underestimated. Also, given the lack of inclusion of laboratory data, such as eGFR, proteinuria (urinary albumin-to-creatinine ratio), HbA1c and cholesterol, the baseline characteristics of the participants who were or were not taking a statin could not be well matched, and this represents a major limitation of these studies.

Consistent with our findings, several previous studies have shown that statins may be reno-protective in patients with diabetes. 50–52 However, these studies were limited by small sample sizes, inconsistent effects on proteinuria and renal function, or the use of an ICD-based method of diagnosis of DKD. More importantly, one of the basic principles of examining effectiveness of medications in cohort studies is excluding prevalent users.53 The exposure in these observational studies including prevalent users of a statin raises concern for bias toward better outcomes.

The strengths of the present study include its real world–based data source, new-user design, large sample size, inclusion of individuals with a wide range of disease phenotypes, and use of hard kidney outcomes. The comprehensive patient-level data with time stamps ensure that thorough weighting of the groups was possible. In addition, we adjusted for important potential confounders, such as comorbidities, concomitant drug administration, the type of statin used and the level of lipid control. Additional strengths include the use of sophisticated statistical methods to reduce the risk of confounding and indication bias. Given the E-values for kidney outcomes in the primary analyses (2.1–2.7), the robustness of the study results do not appear to be substantially affected by the presence of unassessed confounders.46

In our study, we found that various specific statins may have variable effects on kidney outcomes in patients with type 2 DM. A previous RCT that compared the renal effects of atorvastatin and rosuvastatin in patients with diabetes who had proteinuria showed that atorvastatin might be more reno-protective.54 Recently, a real-world study also found that rosuvastatin was associated with increased risk of proteinuria compared with atorvastatin. 55 However, these studies did not include a placebo control; therefore, it could not be determined whether atorvastatin protected the kidney or rosuvastatin harmed the kidney. In the present study, atorvastatin appeared to be most reno-protective, across all kidney outcomes.

Whether the potential reno-protective effect of statins is independent of their lipid-lowering effects remains unclear.56,57 In animal models of diabetes, statin therapy has been shown to cause increases in antioxidant enzyme levels, reduce the accumulation of advanced glycation end products, and reverse diabetes-related podocyte injury, which may prevent or slow the development of kidney disease, independent of the effects of reducing lipid concentrations.58–60 In a post hoc analysis of data from randomized trials,61 the effect of statin treatment on proteinuria was shown to be inconsistent with the degree of control of hypercholesterolemia in individual patients. However, in the present study, intensive control of LDL-C tended to be associated with a better kidney outcome, implying a reno-protective effect driven at least partly by the lipid-lowering effects. Considering the relatively few participants taking other lipid-lowering drugs, which limited the feasibility and statistical power of the comparison between statin and other lipid-lowering drugs, we could not preclude the potential reno-protective effect of statins independent of their lipid-lowering effect.

Although the management of type 2 DM has improved substantially in recent decades, patients with diabetes in China are still at substantial risk of kidney disease and progressive loss of renal function. Our study found that only 36.6% of people with type 2 DM who were age 40 years or older were prescribed statins during the study period, which is lower than that in Canada (54.0% for males and 45.3% for females)62 and the United States (41.6%).63 The current national guideline in China recommends statin therapy for patients with diabetes who are aged 40 years or older.64 The suboptimal accordance with this recommendation might contribute to the higher risk of kidney disease progression we observed in our study population. Our findings suggest that there is an urgent need to promote guideline-concordant care in real-world clinical practice in China.65

Limitations

Although we performed propensity score overlap weighting to balance the baseline characteristics of the statin initiators and noninitiators, other uncontrolled factors could have affected the kidney outcomes. We performed multiple sensitivity analyses to adjust for these residual confounders.

Statin initiation may have represented a marker of atherosclerosis, high health awareness or high frequency of hospital visits, all of which could have resulted in ascertainment bias and influenced the results. However, the number of outpatient visits by the weighted cohort during the follow-up period was similar for statin initiators and noninitiators. We selected our study population from patients with type 2 DM who were admitted to 1 of the 19 urban academic centres in the CRDS and who received follow-up at 1 of the affiliated clinics. These patients might have been sicker and had poorer glycemic control and higher risk of diabetic complications than those who were not admitted to hospital and those without follow-up. As such, caution is needed when generalizing our results to all patients with type 2 DM.

Finally, patients whose data are included in the CRDS are predominantly Chinese; therefore, whether there are ethnic differences in the potential reno-protective effect of statins warrants further research. Additionally, we found that only one-third of inpatients used metformin and statins in our study, reflecting poor adherence to guidelines in China.65 Our findings need to be validated in other countries in which a higher proportion of patients with type 2 DM are receiving guideline-concordant care.

Conclusion

We found that statin initiation was associated with significantly lower risks of incident DKD and kidney function decline among patients with type 2 DM admitted to and followed up in academic centres. We obtained similar results for participants with differing patterns of dyslipidemia, those prescribed different statins, and after stratification according to participant characteristics. Among statin initiators, these associations were more pronounced in those with intensive LDL-C control (< 1.8 mmol/L).

These findings suggest that statin initiation may be an effective approach for preventing kidney disease in patients with type 2 DM. Further research is needed to compare the reno-protective effects of specific statins and newer lipid-lowering drugs, such as proprotein convertase subtilisin/kexin type 9 inhibitors, on kidney outcomes.

How food can be linked to diabetes diagnosis

Diabetes News


Many people are unaware that food is often the best medicine for health issues like diabetes

 
Almost 70 per cent of Australians are overweight or obese and there is a new diabetes diagnosis every 5 minutes in Australia.

And while TikTok trends like taking Ozempic, a diabetes medication that is hailed as the ‘miracle diet drug’, have gained popularity, many are unaware that food is the best medicine for health issues.

Kate Save, Co-Founder and CEO of Be Fit Food, joined us to discuss.

Volunteers for Diabetes providing support services for diabetics | Hancock County Journal-Pilot

Diabetes News


In 1987, the Hancock County Volunteers for Diabetes was formed in an effort to provide a variety of support services to diabetics living in Hancock County. The volunteers have been able to provide a limited amount of financial support for diabetes medications or supplies, lab work, eye or dental exams, nutrition counseling or other special needs. Over the years, the Volunteers for Diabetes have also planned the Annual Diabetes Spotlight, a day-long educational event, typically held in November. This event is particularly beneficial for diabetics and their families, as there are presentations on diabetes topics and educational information distributed by exhibitors. Years ago the volunteers sponsored a Diabetes Support group. The volunteers are hopeful to begin offering a Diabetes Support Group to diabetics and their families in the near future.

Jeera or cumin helps reduce blood sugar. So have it roasted, whole or powdered

Diabetes News


Cumin seeds, also known as jeera, are widely used to temper food and enhance its flavour in a variety of preparations. These dried seeds are of the herb Cuminum cyminum, a member of the parsley family. They have numerous health benefits and are commonly used in Asian households to fight off stomach woes, soothe the digestive tract, relieve nausea, bloating and constipation. In fact, they are routinely used for digestive efficiency and health but cumin seeds are also used as an adjuvant therapy along with oral medication in people with Type 2 diabetes.

Some studies have found that cumin seeds can help regulate fasting blood sugar levels in people with Type 2 diabetes. This may be due to the presence of certain compounds in cumin seeds, such as cumin aldehyde, which have been shown to have anti-diabetic effects. The blood glucose lowering potential of cumin is also attributed to the presence of thymoquinone, an active chemical component that protects the B-cells of the pancreas from oxidative stress. It helps stimulate the insulin production in the body, which can help to keep the blood sugar levels in check.

Consuming cumin either as whole seeds or in the form of ground powder may help in managing blood sugars in diabetics. It not only lowers blood glucose levels but also helps maintain a healthy body weight. It may help lower levels of LDL (low density lipoprotein) and triglyceride levels. Cumin seeds have anti-inflammatory properties, which may be beneficial for reducing the risk of complications associated with diabetes, such as cardiovascular disease. These are also a good source of antioxidants, which can help protect against cell damage and may be particularly beneficial for people with diabetes, who are at increased risk of oxidative stress.

While there may be some potential benefits of cumin seeds for people with diabetes, more research is needed to fully understand the relationship between cumin seeds and diabetes. However, a string of studies over decades has established a definite correlation. Way back in 1998, an eight week dietary regimen containing cumin powder in streptozotocin-induced diabetic rats was found to be remarkably beneficial, as indicated by reduction in hyperglycemia. This was also accompanied by improvement in body weights of diabetic animals. Dietary cumin countered other metabolic alterations as revealed by lowered blood urea level and reduced excretions of urea and creatinine by diabetic animals.

Seeds of Nigella sativa (black cumin/kalonji) were found to have anti-diabetic properties in a study conducted in 2011. Thymoquinone (TQ), a volatile oil, is one of its active constituents but antidiabetic activity has also been shown by its aqueous extract and defatted extract. The study said, “N. sativa may be beneficial in diabetic individuals and those with glucose intolerance as it reduces appetite, glucose absorption in intestine, hepatic gluconeogenesis, blood glucose level, cholesterol, triglycerides, body weight and simulates glucose induced secretion of insulin from beta-cells in pancreas; improves glucose tolerance….yet it has not shown significant adverse effects and has very low toxicity. In streptozotocin (STZ) induced diabetic rats it causes gradual partial regeneration of pancreatic beta-cells, increases the lowered serum insulin concentrations and decreases the elevated serum glucose.”

According to a study to evaluate the effect of 50 and 100 mg doses of green cumin essential oil on glycaemic and inflammatory indices in patients with Type 2 diabetes, it was established how administering cuminum cyminum supplement (or cumin) in such patients could decrease the serum levels of insulin, fasting blood sugar and glycosylated haemoglobin. In addition, it was found to control the complications of Type 2 diabetes in these patients.

In another study, which was published in ‘Nutrition and Metabolism,’ cumin not only lowered blood glucose levels but helped people maintain a healthy body weight, which is one of the potential causes of diabetes in the first place.

In a 2018 study, crude ethanol extract of cumin seeds was found to be very helpful in the improvement of plasma lipid profile as one of the risk factors for cardiovascular diseases and heart failure in diabetic patients.

That being said, there are several ways to incorporate cumin seeds into your diet. Here are a few ideas:

1. Sprinkle cumin seeds on roasted vegetables or grilled meats for added flavour and nutrition.
2. Use cumin seeds in home-made spice blends for soups, stews, and other dishes.
3. Brew cumin seed tea by boiling a teaspoon of cumin seeds in a cup of water for 5-10 minutes.
4. Mix ground cumin seeds into salad dressings, dips, or sauces.
5. Add cumin seeds to lentil or bean dishes to enhance the flavour and nutrition.
6. You can add roasted jeera seeds to your food or grind it into a powder and sprinkle it over salads, yogurt, buttermilk and cut fruits.
7. One can simply chew on 1 tsp of roasted jeera after meals every day.

A word of caution, consult your diabetologist and dietitian about the amount of supplement to be taken should you already be on medication to control blood sugar.
