Keywords: lipids; metabolic syndrome; obesity; prevention; hyperlipidemia
The metabolic disorders are main and increasing public-health and clinical challenge worldwide because of urbanization, excessive energy intake, increasing obesity, and sedentary life styles. According to International Diabetes Federation (IFD) diabetes is one of the major metabolic disorders and a dangerous risk factor for heart problems. Twenty five percent of the world’s adults have metabolic disorders. Recently in year 2013 the American Heart Association also reported that adults have abnormal serum lipid profile. Allopathic drugs used as hypolipidemic agents have number of unwanted effects. Herbal therapy for Hyperlipidemia is getting attention due to their less frequent side effects. In this study we have compared hypolipidemic effects of Fenofibrate 40 mg with Nigella sativa. Seventy five hyperlipidemic patients from National Hospital Lahore were enrolled for study. Consent was taken from all enrolled participants and were divided in three equal numbers ie; twenty five in each group. Group 1 was on Nigella sativa, group 2 was on Gemfibrozil and third group was on placebo therapy. They were advised to take drugs for two months. After completion of study pretreatment and post treatment values of LDL cholesterol were analyzed statistically. In 25 patients who were on Nigella sativa, their LDL cholesterol decreased from 191.14±3.45 to 159.40±2.98 mg/dl. 31.7 mg/dl LDL reduction was observed when compared with placebo group. In 25 patients who were on Fenofibrate 40 mg, their LDL cholesterol decreased from 197.77±3.91 mg/dl to 159.62±2.20 mg/dl. LDL reduction in this group was 38.2 mg/dl. These changes are highly significant with p-values of <0.001. We concluded from this study that hypolipidemic characteristic of Nigella sativa is comparable and therapeutically as effective as traditionally used hypolipidemic medication Fenofibrate.
Persons with metabolic syndrome (MS) are twice as likely to die from, and thrice as likely to have a heart attack or stroke as compared with others. Type 2 diabetes mellitus is one of the most common chronic diseases in the whole world and the fourth or fifth leading cause of death in the developed countries; it accounts for 90 percent of all diabetes and has become one of the major causes of premature ill health and death - mainly through the increased risk of cardiovascular disease (CVD) which is responsible for up to 80 percent of these deaths. As per a projection, there will be about 23.3 million deaths by CVD worldwide by 2030 [1]. Hyperlipidemia is one of the major reason for development of MS [2]. In human body free radicals are formed in consequence of various metabolic processes. If there is abundance of low density lipoprotein particles in plasma, there are chances of risk to develop CAD (coronary artery disease) when free radicals interact with LDL particles. CAD may lead to morbidity and mortality due to cardiac arrest in human population [3]. In some cases, atherosclerotic plaques may totally block the blood supply to the myocytes, causing cardiac attack [4]. Atherosclerotic plaque contains calcium, cholesterol, free fatty acids, and macrophages in variable amount. These plaques are of two types ie; hard and soft. Soft plaques are more vulnerable than hard and can rupture easily as compared to hard one. There are risks for ischemic stroke too if blood supply to neurons ensues [5]. Hypolipidemic drugs can be used to prevent hyperlidemia, CAD, heart arrhythmias and cardiac arrest. Allopathic drugs used to prevent or cure Hyperlipidemia include Statins, Fibrates, niacin and bile acid binding resins [6]. If Fenofibrate is used, there is increased synthesis of high density lipoprotein particles in plasma. In patients suffering from hyperlipidemia, Fenofibrate enhances turnover of tissue cholesterol, thus reducing lipoprotein particles. Apo proteins in LDL are also changed by Fenofibrates leading to high affinity for the low density lipoprotein receptors to LDL particles [7, 8]. Nigella sativa or kalonji contains conjugated linoleic acid, thymo-quinone, melanthin, nigilline, damascenine, and trans-anethole. Thymoquinone (TQ) extracted from Nigella sativa (kalonji) inhibits iron-dependent microsomal lipid peroxidation. Stimulation of polymorph nuclear leukocytes with thymoquinone works as protector against damaging effects of free radicles generated biochemically in human body [9, 10]. Prehistorically Nigella sativa is being used to treat, inflammation, high plasma lipids, high blood pressure, asthma, diabetes mellitus, arthritis, and gastrointestinal problems [11, 12]. Worldwide, the first curative line of metabolic disorder was non-pharmacologic actions consisted of diet and lifestyle changes as well as appropriate care in order to decrease mortality and morbidity of such diseases. However, the major concern for medical scientists to find pharmacologic approach, and to increase the efficacy of chronic drug treatment. Medical researchers do have tendency to find curative agents among traditional sources. As per World Health Organization (WHO) about 70 percent population of entire world depends upon traditional and folk medicines. In India, about 80 percent of the rural population depends upon traditional and folk medicines for their health care. In this respect, many plant extracts have been assessed for their efficacy in metabolic disorders and hyperlipidemia; the Kasni (Cichorium intybus) is one of them, having a long history of therapeutic use in traditional medicine for many diseases specially diabetes [13, 14].
Design of research work: It was single blind placebo controlled study. VENUE: The research work was conducted at National Hospital Lahore, Pakistan from February to July 2019.
Sample size and inclusion criteria: 75 hyperlipidemic patients were enrolled whose age range was from 18 to 70 years. Well explained, written consent was taken from all participants.
Exclusion criteria: Hypothyroidism, peptic ulcer, diabetes mellitus type-I and type-2, any major cardiac, renal and hepatic illness.
Grouping and methodology: Enrolled patients were divided in three equal numbers i.e.; 25 patients in Group-1, 25 in Group-2, and 25 patients in Group-3. Baseline LDL -cholesterol of all patients was determined in Biochemistry laboratory of the hospital. Separate folder was designed for each enrolled patient, in which their personal data, medical history, laboratory reports, follow-up visit proforma were kept. Their plasma
LDL-cholesterol was calculated by Fried Wald formula7 (LDL-C = Total cholesterol-(Triglycerides/5 + HDL-C). 25 patients of group-1 were advised to take eight grams of Kalonji (Nigella sativa) in two divided doses for two months. 25 patients of group-2 were advised to use 40 mg Fenofibrate tablets twice daily for two months. 25 patients of group-3 were advised to take Capsule (Placebo capsule containing grinded wheat powder) twice daily for two months. They were advised to take their medication after breakfast and after dinner. All participants were convinced to go for 20 minutes brisk walk at morning or evening time. Fortnight follow up visit was arranged for all participants. After two months research period their lipid profile was determined in same laboratory of the hospital.
Statistical Analysis: Mean values of LDL-cholesterol ±SEM were analyzed statistically by using SPSS 2014 version. Paired t-test was applied to analyse pre-treatment and post treatment values. p<0>0.001 was marked as highly significant change in the tested parameter.
When results were compiled and statistically analyzed, it was observed that Nigella sativa and Fenofibrate 40 mg decreased LDL-cholesterol significantly. Nigella sativa decreased LDL cholesterol from 191.14±3.45 mg/dl to 159.40±2.98 mg/dl. This change in mean values was 31.7 mg/dl with highly significant p-value of <0>0.05.
Normal plasma lipid levels are required to keep heart healthy. Statins, Fibrates, Bile Acid Binding Resins, and Niacin (Vitamin B3) are used as hypolipidemic medicines in allopathy, but all these have unwanted effects. In Ayurveda discipline of therapeutics, various herbs, fruits and vegetables are used to reduce bad-cholesterol (LDL-C) and to increase good-cholesterol (HDL-C). In various research study results Kalonji is labeled as hypolipidemic therapeutic agent but little research work is done on comparison of its hypolipidemic potential with allopathy related hypolipidemic medicines. This research was targeted to compare its hypolipidemic characteristics with one of the Fibrate i.e. Fenofibrate 40 mg. In our results it was observed that Kalonji or Nigella sativa reduced LDL-cholesterol 31.7 mg/dl which is almost 16.58 % reduction in the parameter. This change is highly significant (p<0>
