Objectives: The aim was to investigate the frequency and the particularities of arterial hypertension (AH) in type 2 diabetes patients treated in the nephrological clinic at the Department of Nephrology and Dialysis, the Internal Medicine Clinic, Clinical Hospital Center Split, and whether there is any correlation with parameters of nutritional status. Material and Methods: The study included 106 participants, 66 (62.3%) men and 40 (37.7%) women, average age 69.5 (range 36-75 years). For each patient following data were recorded: patient's age, gender, body weight and height, waist and hip circumference, existence of AH, cardiovascular disease, chronic kidney disease (CKD), type and number of antihypertensive drugs taken, type of therapy for type 2 diabetes and statin data. Urea and creatinine serum values were determined and the estimated glomerular filtration rate (eGFR) and body mass index (BMI) were calculated. The level of albuminuria was also noted. Furthermore, serum values of triglycerides, cholesterol levels, LDL, haemoglobin, urate, glucose and potassium were determined for each participant. The "Agedio B900" device was used to measure arterial pressure. Values of pulse wave velocity (PWV), peripheral (PSAP) and central systolic arterial pressure (CSAP) as well as the values of peripheral (PDAP) and central diastolic (CDAP) arterial pressure were measured. Pulse pressure (PP) and mean arterial pressure (MAP) for peripheral and central arterial pressure were calculated. Also, weighing with the help of Tanita MC780 Multi Frequency segmental body composition analyser values of body fat, muscle mass, skeletal muscle mass (data for all the mentioned parameters were expressed in percentages and kilograms) as well as fat free mass (kg) and bone mass (kg) were determined. Results: The results showed that 99 (93.4%) participants had the diagnosis of AH. Out of the total number of participants (N=106), 45 (42.5%) participants were taking statin therapy and 103 (97.2%) were taking antihypertensive therapy. The results showed that 40 (38.3%) participants were taking fixed-dose combination while 61 (58.2%) were taking three or more antihypertensive drugs one of which is diuretic. Furthermore, the study showed that 62 (58.5%) participants had diagnosis of chronic kidney disease (CKD) while 70 (66%) participants had eGFR < 60 mL/min/ 1.73m2. Also, 14 (13.2%) participants had coronary disease mentioned in the history of disease. Statistically significant higher frequency of coronary disease was found among the participants that had diagnosis of CKD (p=0.030). The results showed that statistically significant differences exist in the body composition parameters between men and women with AH, but no statistically significant differences were found in the arterial pressure parameters between men and women. Also, results showed statistically significant positive correlation of BMI and CDAP (ρ=0,279, p=0.010) and PDAP (ρ=0.261, p=0.010). Statistically significant correlation was also found between BMI and MAP for central arterial pressure (CAP) (ρ=0.271, p=0.010) as well as BMI and MAP for peripheral arterial pressure (PAP) (ρ=0.206, p=0.040). However, statistically significant correlation was not found for the body composition parameters and measured central and peripheral arterial pressure parameters among the patients with AH. Furthermore, statistically significant differences were found among the body composition parameters but statistically significant differences were not found between the values of the arterial pressure among the three groups of participants (patients with normal weight, overweight patients and obese patients). The results showed that statistically significant negative correlation exists between the duration of the antihypertensive therapy and level of albuminuria in the patients with type 2 diabetes (ρ=-0.508, p=0.007) who are being treated in the nephrological clinic. However, statistically significant correlation was not found between the duration of therapy for type 2 diabetes and the level of albuminuria among the patients with type 2 diabetes and AH. Conclusions: The results show that prevalence of AH, resistant AH and CKD is high among the patients with type 2 diabetes. Furthermore, significant number of patients with type 2 diabetes are unaware of the existence of CKD and that is population of patients with a higher frequency of coronary heart disease. All these results indicate the importance of timely detection and adequate treatment of AH in the population of type 2 diabetes in order to prevent the occurrence and progression of unwanted complications (CKD, cardiovascular events, obesity, and worsening of albuminuria) that increase the morbidity and mortality of this patient population.
