Type 2 diabetes mellitus (T2DM) is a common metabolic disease characterised by insulin resistance and elevated blood glucose levels, affecting millions of people worldwide. T2DM individuals with dyslipidaemia have an increased risk of cardiovascular disease (CVD). A complex interplay of risk factors such as hyperglycaemia, dyslipidaemia, hypertension, obesity, inflammation, and oxidative stress favour the development of atherosclerosis, a central mechanism in the pathogenesis of cardiovascular disease. Dyslipidaemia, a hallmark of T2DM, is characterised by elevated triglycerides, decreased high-density lipoprotein (HDL) cholesterol and the presence of small, dense low-density lipoprotein (LDL) particles, all of which promote atherosclerosis. In this article, we have attempted to present various treatment strategies that include pharmacological interventions such as statins, ezetimibe, PCSK9 inhibitors, fibrates, and omega-3 fatty acids. We have also tried to highlight the pivotal role of lifestyle modifications, including physical activity and dietary changes, in improving lipid profiles and overall cardiovascular health in T2DM individuals. We have also tried to present the latest clinical guidelines for the management of dyslipidaemia in T2DM individuals. In conclusion, the treatment of dyslipidaemia in T2DM individuals is of great importance as it lowers lipid particle levels, slows the progression of atherosclerosis, and ultimately reduces susceptibility to cardiovascular disease.

Inflammatory bowel diseases are a group of chronic inflammatory conditions that affect gastrointestinal tract due to inapt and continuous immune activation in response to a myriad of predisposing factors (most notably genetics, environmental impact and gut microbiota composition). It has been shown that vitamin D status can also play a role in the disease pathogenesis, as its deficiency is commonly observed in two major forms of inflammatory bowel diseases - Crohn's disease and ulcerative colitis. Mounting evidence supports the concept of intricate relationship between gut dysbiosis and vitamin D metabolism, while suboptimal levels of this vitamin have been linked to increased clinical disease relapse rates, inadequate response to drugs, as well as decreased quality of life in patients with Crohn's disease and ulcerative colitis. Consequently, the pertinent question is whether increased vitamin D supplementation and (on a population level) food fortification may bring significant benefit to the affected individuals. In this short review we discuss the synthesis, functions, status and food sources of vitamin D, appraise biotechnological facets of vitamin D status analysis and food fortification, and concentrate on novel developments in the field that describe its influence on intestinal microbiota and inflammatory bowel disease.

Background/Objectives: Lipoprotein (a) [Lp(a)] plays a significant role in atherosclerosis and cardiovascular disease (CVD). Genetic regulation of Lp(a) involves variations in the apo(a) LPA gene, as specific polymorphisms like rs10455872 and rs3798220, both linked to higher Lp(a) levels and CVD. CVD remains the leading global cause of death, with high Lp(a) levels increasingly recognized as a significant factor in younger patients with no other CVD risk factors. We aimed to evaluate the association of LPA genetic variations with Lp(a) levels and its effect on cardiovascular risk as there are existing inconsistent findings. Methods: This case–control study included 251 subjects with a median age of 52 years (interquartile range, IQR = 17) and elevated Lp(a) levels. Cases were subjects who experienced early cardiovascular incidents (women < 65, men < 55 years old), and the control group included subjects without such history. Genotyping of LPA gene polymorphisms (rs10455872 and rs3798220) was performed, and demographic data with Lp(a) levels were collected. To evaluate the association between the LPA genotypes and the risk of cardiovascular incidents (CVI), several logistic regression models were performed. The cut-off points for Lp(a) levels were determined using diagnostic test accuracy measures. Results: The rs3798220-C allele was associated with higher Lp(a) levels (288 ± 166 nmol/L in cases vs. 189 ± 102 nmol/L in controls, p < 0.001) and myocardial infarction (53% in cases vs. 36% in controls, p = 0.036). Among cases, 28.9% carried the rs3798220-C allele, compared to 18.7% in controls. The rs10455872-G allele was slightly more prevalent in controls (34.15% vs. 29.69%) but without further significant associations. In this study, the cut-off Lp(a) value of 151 nmol/L, for patients with a positive family history of early CVD, is associated with a higher chance of developing CVI. Conclusions: This study demonstrates an association between the LPA rs3798220-C allele and higher Lp(a) levels, as well as an increased risk of early onset myocardial infarction. However, the obtained association should further be evaluated at a much larger scale.

Lipoprotein (a) is a highly atherogenic, lipid particle whose concentration is genetically determined, and represents an independent risk factor for cardiovascular disease. On the other hand, metabolic syndrome represents a cluster of interconnected cardiovascular risk factors (obesity, insulin resistance, arterial hypertension, dyslipidemia) that are a direct consequence of an unhealthy lifestyle. Some evidence suggests a connection between each component of metabolic syndrome and high levels of lipoprotein (a). Still, the exact mechanisms are not fully understood and may involve complex interactions between various metabolic pathways. High levels of lp(a) are associated with insulin resistance, a key feature of type 2 diabetes mellitus and obesity. Although there is no significant association between lp(a) and other lipid levels (LDL-C, HDL-C, triglycerides), studies have shown a strong synergistic effect of genetically elevated LDL-C and Lp (a) on the development of cardiovascular events. Also, there is supporting evidence that hypertensive patients with high levels of lp(a) have higher cardiovascular risk, there is no direct association between hypertension and lp (a). Treatment of metabolic syndrome is often long-term and challenging but very important to reduce the overall cardiovascular risk, especially in individuals with higher levels of Lp (a), in whom the risk of developing cardiovascular disease is much higher.
