Abstract

New-onset diabetes is a serious condition and is characterised by insulin resistance and dyslipidemia affecting adults and more lately children. Diabetic dyslipidemia is characterised by high plasma triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C) particles, and low high-density lipoprotein cholesterol (HDL-C). Individuals with dyslipidemia have high 10-year risk of atherosclerotic cardiovascular disease (ASCVD) and can be managed by adopting therapeutic lifestyle changes (TLC) and medication adherence. The new American College of Cardiology/American Heart Association (ACC/AHA) guideline emphasized on matching the intensity of statin treatment to the level of ASCVD risk and replaces the old paradigm of LDL-C target based treatment, and the new guidelines of National Lipid Association (NLA) have recommended a multifaceted approach for the management of dyslipidemia. Both ACC/AHA and NLA have recommended statin as the main stay of drug therapy in patients with high cholesterol. Medication non adherence is a frequent problem in developing countries because of low income and high cost of drug which are sometimes required for duration. TLC has been reported to aid drug therapy to provide best medication benefit but lack of knowledge and illiteracy is another limitation to achieve maximum benefits from drug therapy in India.

In conclusion, TLC and medication adherence is important for dyslipidemia management with lipid lowering drugs, and healthcare providers should provide knowledge on benefits of TLC and medication adherence in countries with Low income/socio-economic status

Introduction

New-onset diabetes is a serious condition that adversely affects the body’s ability to regulate glucose. The new-onset diabetes is characterized by a form of insulin resistance that historically affected individuals in adulthood. In recent years, however, diagnoses of this disease have become prevalent in children. It is often observed that people who are obese and insulin resistant often have a dyslipidemia. Dyslipidemia is commonly characterized by elevated blood triglyceride (TG) concentrations and low high-density lipoprotein cholesterol (HDL-C) [1]. These characteristic are also considered important cardio-metabolic risk factors, increase the risk of macrovascular and microvascular complications in type 2 diabetes for the development of cardiovascular diseases [2]. Dyslipidemia consisting of high TGs and low HDL-C is a widely recognized lipid pattern that is frequently associated with the development of coronary heart disease. Study has suggested that dyslipidemia in diabetic patients should be treated for primary prevention with the same intensity recommended for secondary prevention in heart patients, before the development of cardiovascular disease [3]. Strict adherence to treatment is essential to avail maximum benefits of therapy. Further, Therapeutic Lifestyle changes (TLC) have been reported to reduce LDL-C, TG, blood pressure, glucose and body weight and increase HDL-C level and have greatly complemented the drug therapy [4]. Therefore, strict adherence to the prescribed therapy and TLC are key to obtain optimum therapeutic benefits. In poor countries like India and others, socio-economic states are major determinant of medication continuation and play an important role in deciding adherence rate. There has been a significant association between patients with low-income and non-adherence to drugs, and high cost of newer oral hypoglycaemic agents have hindered optimal adherence to the treatment [5].

We present here a case report of effective management of dyslipidemia in a new-onset type 2 diabetic with TLC and strict adherence to pharmacological treatments.

Case report

A 60-year old man with new-onset, type 2 diabetes mellitus visited a tertiary care hospital in India. His weight and height was 80 kg and 5’9”. He had a body mass index of 26 kg/m2 and blood pressure measured as 140/90mm Hg. He had a sedentary lifestyle, mild polyphagia, and presented with nonspecific complaints of fatigue and lack of general sense of well-being. The patient had strong positive family history of cardiovascular diseases (CVD), his father had myocardial infarction (MI) which proved to be fatal, mother and elder sister had type 2 diabetes and younger brother had an ischemic stroke 5 years ago. Laboratory findings showed total cholesterol as 227 mg/dL, HDL-C levels as 40 mg/dL, LDL- as 125 mg/dL, TG as 140 mg/dL, fasting blood glucose as 104 mg/dL, and glycated haemoglobin (HbA1C) as 8%. Patient was taking metformin plus atorvastatin (500 mg + 10 mg, once daily) for past 3 months but had poor adherence to treatment. His 10-year risk of atherosclerotic cardiovascular disease (ASCVD) risk was calculated as 23.5% using pooled cohort risk assessment equations.

After strict adherence to the prescribed treatment (metformin and atorvastatin) and lifestyle modifications, his HbA1C level improved to 7% and LDL-C dropped to 73 mg/dL at 3-month follow-up.

However, there was no significant improvement in HDL-C and TG levels after initiation of atorvastatin. During treatment, the clinician increased the atorvastatin dose to 80 mg/day which further reduced LDL-C level. The high atorvastatin dose was well-tolerated by the patient with no elevations of alanine/aspartate aminotransferase. At 6-month follow-up, the LDL-C level again rose to 85 mg/dL, which was found to be due to medication noncompliance.

Discussion

The present case report highlights how life style modification and strict adherence to treatment can effectively manage diabetic dyslipidemia in type 2 diabetes.

Lifestyle changes, including increased physical activity and dietary modifications remains the cornerstone of management of atherogenic dyslipidemia in type 2 diabetes [6-8]. In our report, when the lifestyle of the patient was modified and he strictly adhered to the treatment as suggested by the physician, his HbA1c and LDL-C levels significantly improved.

Our findings are in concordance with earlier reported literature where intensive lifestyle interventions yielded better long-term impact on cardiovascular morbidity and mortality in overweight patients with type 2 diabetes than standard diabetes support and education programs [9]. Similarly, stepwise introduction of lifestyle modification with pharmacologic interventions helped to reduce the risk of deaths (53%) due to CVD, nonfatal MI, percutaneous coronary interventions, nonfatal stroke, and coronary artery bypass grafting in patients with type 2 diabetes and microalbuminuria [10]. Metformin is most prescribed oral antidiabetic agent [11]. Statins, the lipid-lowering therapy, is the recommended initial pharmacological treatment for lowering LDL-C levels in “very high risk” and “high-risk” categories of type 2 diabetes. Atorvastatin is one of the most worldwide prescribed statins [12].

Looking at the calculated 10 year risk of ASCVD of the patient, he was at an elevated 10-year risk (≥ 7.5%) for ASCVD. As per the Pooled Cohort Risk Assessment Equation, a high-intensity statin should be considered for this patient who has a 10-year ASCVD risk ≥ 7.5% and fall in the age bracket of 40-75 years and also have LDL 70-189 mg/dL. The 2013 American College of Cardiology (ACC)/American Heart Association (AHA) have recommended either a high-intensity or moderate-intensity statin regimen in patients who have an elevated ASCVD risk (≥ 7.5%) for primary prevention of cardiovascular disease [13]. The new ACC/AHA guideline emphasizes matching the intensity of statin treatment to the level of ASCVD risk and replaces the old paradigm of pursuing LDL-C targets. While, the new guidelines of National Lipid Association have recommended a multifaceted approach to incorporate each patient risk and risk factors, rather than specific medication categories for the management of dyslipidemia. An elevated level of atherogenic cholesterol is regarded as the root cause of atherosclerosis, the key underlying process contributing to most clinical ASCVD. Hence, reducing elevated levels of atherogenic cholesterol particles has been recommended to lower ASCVD and can be achieved by atherogenic cholesterol lowering through multiple modalities, including lifestyle and drug therapies. The intensity of risk-reduction therapy should be individualised based on the patient's absolute risk for an ASCVD event and, both intermediate-term and long-term/lifetime risk should be considered when assessing the potential benefits and hazards of risk-reduction therapies [14]. Both NLA and ACC/AHA recommend statin treatment as the mainstay of drug therapy to reduce ASCVD risk in patients who have been considered for treatment with lipid-lowering drug therapy. Further, NLA recommends management of non-lipid ASCVD risk factors particularly high blood pressure, cigarette smoking, and diabetes mellitus.

The ACC/AHA have recommended 80 mg (40 less preferred) dose of high intensity atorvastatin. Hence, atorvastatin dose was increased from 10 mg to 80 mg. He was advised to adopt TLC as the 2013 ACC. AHA guideline have laid extra emphasis on lifestyle modification (i.e., adhering to a heart healthy diet, regular exercise habits, avoidance of tobacco products, and maintenance of a healthy weight). TLC constitutes an important element in the health promotion and ASCVD risk reduction, both prior to and in concert with the use of cholesterol lowering drug therapies. TLC is a comprehensive lifestyle approach thatincludes specific dietary recommendations (TLCdiet), weight management, and increased physicalactivity. The TLC emphasizes reducing dietary cholesterol (<200 mg/day), saturated fats (<7% of total calories), and trans fats (lower intake). Total fat comprises 25–35% of total calories, with up to 20% coming from monounsaturated fats and 10% from polyunsaturated fats. The optional nutrient considerations for augmented LDL-C reduction and reducing coronaryheart disease risk include stanols/sterols (2 g/day) and viscous (soluble) fibers (5–10 g/day), and including fish (especially oily fish such as salmon, tuna, and mackerel) as part ofone’s overall eating plan [4].

After the use of high intensity atorvastatin dose (80 mg/day), his significantly LDL-C reduced with no adverse events indicating that the dose was safe. The diabetes atorvastatin lipid intervention (DALI) study have reported that either 10 or 80 mg of atorvastatin is equally effective in the treatment of diabetic dyslipidemia [15]. In 2008, Balasubramanian et al. in a study on Indian patients assessed the efficacy, safety and tolerability of a fixed dose combination of atorvastatin 10 mg + metformin SR 500 mg in adult Indian patients with diabetic dyslipidaemia. Further, increased dose of atorvastatin was safe in the present case [16]. This was consistent with previous study reporting that atorvastatin initiated at doses of 10, 20, 40, and 80 mg was effective and safe for the treatment of patients with dyslipidemia. It was further stated that the dose of atorvastatin should depend on the percentage reduction needed to achieve an LDL-C goal, patients with or at risk of coronary heart disease may benefit from starting therapy at a higher dose of atorvastatin [17].

Our results went parallel with earlier reported literature where high-dose statins led to significant reduction in the mean LDL-C levels and in the occurrence of major CV events (CHD, stroke, revascularizations) in comparison to low-dose statins [18]. In 2006, Shepherd et al. [19] reported high-dose statin monotherapy as safe with no treatment-related adverse events and no elevated levels of liver enzymes.

In developing and poor economic countries including India, there continues to be low medical education and awareness on effective usage of medications prescribed by doctors. The illiterate and poor patients tend to abruptly quit medication or do not stick to the prescribed dosage regimen of the medication leading to suboptimal use and clinical outcome. Hence, these patients remain undertreated for diseases that can be effectively treated. The interpretation of a recent study in patients with rheumatoid arthritis suggested that patients who were not taking their biological drug on the day agreed with their health-care professional had poorer clinical outcomes than those who did take their drug, emphasising the need for strict adherence to biological therapy in patients with this condition [20].

Medication adherence commonly refers to whether patients take their medications as prescribed (e.g., twice daily), as well as whether they continue to take a prescribed medication, and it is defined as patients who is taking at least 80% of the amount of medication given to him, and is based on days supply of medication divided by the number of days patient should be consuming the medication. This is termed as the medication possession ratio (MPR). Patient with >80% MPR is regarded as poor adherence. Recent study have suggested even MPR ≥ 90% to be a better threshold for considering patient as adherent [21]. Nonadherence to the prescribe therapy is a growing concern to clinicians, healthcare systems, and other stakeholders (eg, payers) because of mounting evidence that it is prevalent and associated with adverse outcomes and higher costs of care [22]. It potentially leads to increase in hospital visit, duration of hospital stay, suboptimal therapeutic benefit and costs of treatment, and it is likely to grow worldwide as patients often take more medications to treat chronic conditions and is common for patients with CVDs. In this case, we have observed that due to medication nonadherence, patient’s LDL-C levels had shoot up from 75 to 85 mg/dL and the beneficial effects of treatment were abolished. Similar results in terms of higher risk of death, nonfatal MI and loss of beneficial effects of statins with abrupt discontinuation were reported in patients with acute coronary syndrome [22].

Conclusion

There continues to be a considerable lack of knowledge among people in developing countries on dyslipidemia which can be effectively managed in type 2 diabetes patients by life-habit modifications such as adoption of TLC in combination with strict adherence to pharmacological interventions. Therefore, there is a need to impart awareness on the dosage, potential side effects, benefits of continuing uninterrupted medication, by clinicians and pharmacists. This would surely translate into effective and optimised management of dyslipidemia which would potentially decrease the occurrence of dyslipidemia in diabetic patients. Hence, health providers in should underscore the benefits of continuing and adhering to the prescribed statin therapy to the patients including TLC.
