CYSTATIN C-A Monitoring Perspective of Chronic Kidney Disease in Patients with Diabetes.

Chronic kidney disease (CKD) is a microvascular complication that frequently affects numerous patients diagnosed with diabetes. For the diagnosis of CKD, the guidelines recommend the identification of the urinary albumin/creatinine ratio and the determination of serum creatinine, based on which the estimated rate of glomerular filtration (eGFR) is calculated. Serum creatinine is routinely measured in clinical practice and reported as creatinine-based estimated glomerular filtration rate (eGFRcr). It has enormous importance in numerous clinical decisions, including the detection and management of CKD, the interpretation of symptoms potentially related to this pathology and the determination of drug dosage. The equations based on cystatin C involve smaller differences between race groups compared to GFR estimates based solely on creatinine. The cystatin C-based estimated glomerular filtration rate (eGFRcys) or its combination with creatinine (eGFRcr-cys) are suggested as confirmatory tests in cases where creatinine is known to be less precise or where a more valid GFR estimate is necessary for medical decisions. Serum creatinine is influenced by numerous factors: age, gender, race, muscle mass, high-protein diet, including protein supplements, and the use of medications that decrease tubular creatinine excretion (H2 blockers, trimethoprim, fenofibrate, ritonavir, and other HIV drugs). The low levels of creatinine stemming from a vegetarian diet, limb amputation, and conditions associated with sarcopenia such as cirrhosis, malnutrition, and malignancies may lead to inaccurately lower eGFRcr values. Therefore, determining the GFR based on serum creatinine is not very precise. This review aims to identify a new perspective in monitoring renal function, considering the disadvantages of determining the GFR based exclusively on serum creatinine.

Clinical and Metabolic Particularities of a Roma Population with Diabetes-Considering Ethnic Disparities in Approaching Healthcare Management.

The Roma population is Europe's largest ethnic minority, yet data on the prevalence of non-communicable diseases remain scarce in medical literature. This study aimed to compare the clinical and metabolic particularities of a Roma population with diabetes with a group of non-Roma. We conducted an observational, transversal study and evaluated 808 adult patients with diabetes mellitus, from a tertiary diabetes care hospital. The prevalence of metabolic syndrome was high among both groups, 94.3% in the Roma patients and 89.1% in the non-Roma. A slightly higher mean value of the triglyceride-glucose (TyG) index was observed among the Roma group (10.07 ± 0.71 versus 9.71 ± 0.82). Among the non-Roma, variables that were significantly associated with the TyG index were glycated hemoglobin (HbA1c), total cholesterol (TC), high density lipoprotein-cholesterol (HDL-c), and low-density lipoprotein-cholesterol (LDL-c), while among the Roma, HbA1c and HDL-c were correlated with this index. There were no differences concerning myocardial infarction; however, the number of patients with a history of stroke was 2.1 times higher in the Roma group compared to the non-Roma group. The prevalence of cardiovascular risk factors, cardiovascular disease, and microvascular complications among the study's Roma population are quite significant, underscoring the importance of ethnic disparities in approaching healthcare management strategies.

Progression of Chronic Kidney Disease to Dialysis in the Roma Population With Type 2 Diabetes Mellitus in Comparison With Caucasian Patients.

Background Chronic kidney disease (CKD) poses a significant health challenge among patients, contributing to substantial morbidity and mortality outcomes. However, there remains a paucity of data within the medical literature on the Roma population, one of the most significant minority groups globally, with studies indicating that these individuals are disproportionately affected by CKD compared to the general population, with higher prevalence rates. Materials and methods We conducted an observational, cross-sectional study from October 2022 to March 2024, evaluating 735 adult patients with type 2 diabetes mellitus, of which 402 were Roma, aged 18 to 89 years, following the hospital's standard protocols for diabetes management, at the "Nicolae Malaxa" Clinical Hospital in Bucharest, Romania, a tertiary care center for diabetes. Results The prevalence of CKD was higher among the Roma patients, reaching 56.50% (n=203), in comparison with the Caucasian group (43.50%, n=156), however, with a lower mean age (55.53±10.56 years versus 63.32±10.04 years). Roma patients with CKD had a higher prevalence of cardiovascular disease compared to Caucasians, including myocardial infarction, stroke, stable angina, and heart failure. Cardiovascular risk factors, such as hypertension, obesity, and dyslipidemia, in patients with CKD, were also more prevalent among the Roma population. Taking into consideration the natural progression of CKD, the anthropometric measurements and laboratory parameters stratified by ethnicity revealed that Roma patients in the very high risk of CKD progression category had a lower mean age, and a lower median duration of diabetes (56.37±10.79 versus 59.92±7.48 years, and 4.00±2.00 versus 10.00±10.30 years, respectively), as well as a more elevated mean waist circumference (WC), body mass index (BMI), total cholesterol (TC), and low-density lipoprotein-cholesterol (LDL-c) compared to Caucasians. Moreover, patients in the very high risk of CKD progression category among both groups showed the highest level of insulin resistance, measured by the triglyceride-glucose (TyG) index (mean value of 10.13±0.60 among the Roma patients, and 10.09±0.82 among Caucasians). Among the study group, weight, WC, BMI, and A Body Shape Index (ABSI) were associated with a very high risk of progression of CKD. In Caucasian patients, it was demonstrated that weight, WC, BMI, ABSI, and triglycerides (TG) have contributed to the very high risk of progression of CKD, while among the Roma patients, no association was found. Conclusion In conclusion, our findings suggested a high prevalence of CKD among both groups. There is still a need for further investigation of additional risk factors, such as genetics, limited access to health education, and appropriate treatments that could synergistically accelerate the progression of CKD among Roma patients.

Diabetes Distress Among the Roma Population From a Tertiary Care Center in Romania.

Background Distress in patients with diabetes is a condition that has received significant attention in recent years; however, data regarding the psychological assessment and the impact of the emotional burden of diabetes among the Roma population are still scarce in the medical literature. Material and methods We conducted an observational, transversal study that included 310 adult patients with diabetes mellitus, aged between 18 and 85 years old, of which the majority (61%) were women; patients were selected from a tertiary hospital providing diabetes care; diabetes distress was evaluated using a standardized questionnaire, the diabetes distress scale (DDS), validated on Romanian patients. Results In the study population, a great proportion of patients showed diabetes distress, with 24.8% (N=82) having moderate distress and 29.7% (N=121) having severe distress. In the Caucasian group, there were significantly more patients without distress than in the Roma patients,while on the contrary, more Roma patients experienced severe distress compared to the opposite group (64.5%, N=78 versus 35.5%, N=43). In the Caucasian group, a statistical significance was observed regarding interpersonal distress, with Caucasian women having a higher score than men. Concerning the Roma patients, total DDS and all subscales´ scores were statistically significant, with Roma women having higher scores than men. A statistical significance was observed between ethnicity and diabetes distress scores, with the Roma population having higher median values than Caucasian patients. It was also demonstrated that the lack of education, a higher diabetes evolution, and a higher glycated hemoglobin (HbA1c) level (above 8%) have influenced the risk of severe DDS in the Caucasian group, while in the Roma patients, employment status (being unemployed) represents a risk factor for severe DDS. Conclusion The Roma patients included in our study experienced higher distress scores compared to Caucasians. These results are substantial as they emphasize the need to include the evaluation of diabetes distress in clinical practice to facilitate the early initiation of intervention measures. There is nevertheless limited data regarding this particular ethnic group; therefore, further research is still needed.
