Abstract: Background: Carotid atherosclerosis (CA) characterized by the thickening of the endothelium of the carotid arteries, is a reflection of generalized atherosclerosis and a surrogate for cardiovascular events. Objectives: To determine the prevalence and associated risk factors for CA in asymptomatic type 2 diabetes mellitus (T2DM) out-patients at NAUTH in Nnewi, Nigeria. Materials and Methods: This was a cross-sectional study that evaluated 142 T2DM out-patients. Relevant data was extracted with a researcher-structured questionnaire. Anthropometric measurements, glycated haemoglobin and fasting lipid profile were done. Carotid intima-media thickness was measured using ultrasongraphy. Ultrasonography of the brachial and pedal arteries was done using ultrasonic pocket doppler device and ankle brachial pressure index calculated. Lastly, the vibration perception threshold was determined using a digital biothesiometer. Data was analyzed using SPSS version 25. Results of categorical variables were presented in tables as frequencies and percentages. The mean values and standard deviation for the continuous variables were calculated. Chi-square test was used to assess the association between CA and categorical variables. The level of significance was set at p < 0.05. Results: The mean age of the 142 subjects was 59.15 ± 11.37 years and the gender distributions comprised 57.7% female and 42.3% male subjects, respectively. The prevalence of CA among the subjects was 49.3% and CA showed significant associations with educational level (X2 = 10.460; p = 0.015), exercise status (X2 = 5.060; p = 0.024), abdominal obesity in male (X2 = 4.659; p = 0.031) and the female subjects, respectively (X2 = 8.874; p = 0.003), and also with diabetic peripheral neuropathy (DPN) (X2 = 8.158; p = 0.004). Conclusion: The prevalence rate of CA was high and depicted a huge burden of cardiovascular morbidities in T2DM subjects. Equally, CA showed significant associations with educational level, exercise, diabetic peripheral neuropathy and abdominal obesity in subjects.

Abstract: Aim of the Study: Early detection of chronic kidney disease (CKD) remains a clinical challenge. Current diagnostic parameters often identify renal dysfunction only after significant parenchymal damage has occurred. This study introduces the Reverse Hepatorenal Index (RHI), a novel ultrasound-based parameter designed to detect early chronic renal parenchymal changes and evaluates the diagnostic accuracy of the Reverse Hepatorenal Index in detecting early chronic renal parenchymal changes compared to conventional parameters. Material and Methods: A prospective observational study was conducted on 150 participants (75 with early-stage CKD and 75 healthy controls) from January 2025 to May 2025. Ultrasound examinations were performed to measure renal and hepatic echogenicity. The RHI was calculated as the below normal values of the ratio of hepatic cortical echogenicity to renal cortical echogenicity. Serum creatinine, estimated glomerular filtration rate (eGFR), and urinary biomarkers were measured for comparison. Results: The mean RHI was significantly lower in patients with early CKD (0.78 ± 0.12) compared to healthy controls (1.15 ± 0.09) (p<0.001). RHI demonstrated a sensitivity of 86.7% and specificity of 90.7% for detecting early renal parenchymal changes at a cut-off value of 0.92. The area under the ROC curve for RHI (0.924) was superior to serum creatinine (0.756) and comparable to eGFR (0.889). Conclusion: The Reverse Hepatorenal Index represents a promising non-invasive parameter for early detection of chronic renal parenchymal changes. Its superior performance compared to traditional markers suggests potential clinical utility in CKD screening and monitoring.
