Cardiovascular risk assessment prior to kidney transplantation.

OBJECTIVES: The objective was to find out risk factors indicating the patients directly to selective coronarography (SCG) to avoid unnecessary non-invasive testing and in their absence to asses low cardiovascular risk and faster inclusion on the waiting list. BACKGROUND: Cardiovascular diseases (CVD) are the most frequent cause of death in dialysed patients. The aim of our retrospective analysis was to identify risk factors for coronary artery disease (CAD) before kidney transplantation (KTx). METHODS: Our retrospective analysis consisted of 55 dialysed patients (46 males, 9 females, p < 0.0001), undergoing SCG before KTx. We divided the patients according to SCG results (negative, n = 40, positive finding, n = 15). RESULTS: We confirmed a significantly lower incidence of diabetic nephropathy (p = 0.0484), ischaemic heart disease (p = 0.0174) and CAD (p = 0.0001) in patients without percutaneous coronary intervention (PCI; negative finding). Haemodynamically significant coronary stenosis correlated with the occurrence of stroke in a patient's history (p = 0.0104). We identified predictors for performing PCI (positive result): type 2 diabetes mellitus (DM) (p = 0.0472), high-density lipoprotein cholesterol ≤ 1.03 mmol/l (p = 0.0359), total calcium level ≤ 2 mmol/l (p = 0.0309), phosphate level ≥ 1.45 mmol/l (OR 0.2034; p = 0.0351). CONCLUSION: In our analysis, patients with DM and poorly managed chronic kidney disease/mineral bone disease were the riskiest subset of the patients with a positive SCG finding (Tab. 4, Fig. 2, Ref. 30).

Kidney transplantation as a treatment of choice for AA amyloidosis due to periodic fever syndrome.

Renal AA amyloidosis is the most serious complication of periodic fever syndrome, which, inadequate suppression, due to persistent inflammation, leads to nephrotic syndrome and renal failure over several years. In most cases, periodic fever syndromes begin to manifest clinically in early childhood. Occurrence in adulthood is considered rare and is associated with a poorer clinical course. Kidney transplantation (KT) is an effective and safe treatment for end-stage chronic kidney disease (CKD) based on AA amyloidosis. In this paper, we present cases of two patients after deceased donor KT, who have been diagnosed with adult periodic fever syndrome. In the first one, diagnosis and treatment began in advanced stage of CKD and therefore underwent KT with compensated disease, while in the second patient, the disease manifested and diagnosed in the post-KT period. Timely initiation of treatment ensured protection of the graft from amyloid deposition.

The role of proteinuria, paricalcitol and vitamin D in the development of post-transplant diabetes mellitus.

INTRODUCTION: Post-transplant diabetes mellitus (PTDM) occurs most frequently during the first year after transplantation. We focused on parameters of calcium-phosphate metabolism and proteinuria as possible new risk factors for PTDM after kidney transplantation. MATERIALS AND METHODS: We have prospectively identified risk factors for post-transplant diabetes mellitus with follow-up of 12 months in a set of 167 patients after kidney transplantation. Patients with diabetes mellitus type 1 and type 2 as well as patients using ciclosporin A or mTOR inhibitor have been excluded from the monitoring. From the perspective of immunosuppression it was a homogeneous set of patients. RESULTS: We identified the following independent risk factors for PTDM in our set: average proteinuria > 0.300 g/24 h (HR 3.0785, (95 % CI 1.6946-5.5927), p=0.0002), level of vitamin D<20 ng/ml (HR 5.4517, (95 % CI 2.3167-11.8209), p1.45 mmol/l (HR0.0821, (95 % CI0.0042-1.5920), p=0.0439). The lowest occurrence of PTDM and proteinuria was recorded in patients whose treatment included paricalcitol (p<0.0001) and these patients had at the same time the highest level of vitamin D (p<0.0001). CONCLUSION: Deficit of vitamin D, proteinuria and hyperphosphatemia have been independent risk factors for the development of PTDM in our set. We identified the usage of paricalcitol as protective factor with regard to the PTDM development (Tab. 6, Fig. 4, Ref. 29).

Incidence of Diabetes Mellitus After Kidney Transplantation in Slovakia: Multicentric, Prospective Analysis.

BACKGROUND: The incidence rate of post-transplant diabetes mellitus (PTDM) after kidney transplantation (KT) is 5% to 40%. The objective of this analysis was to identify the risk factors of PTDM after KT in the Slovak Republic (SR). METHODS: In the group of 133 patients/non-diabetics, we identified the risk factors of PTDM in the monitored period of 12 months from transplantation. RESULTS: The incidence of PTDM in the SR in 2014 was 38.3%. By logistic regression, we discovered that the age at the time of KT [odds ratio, 1.0885; 95% CI, 1.0222-1.1592; P = .0082], the value of body mass index (BMI) at the time of KT [odds ratio, 1.4606; 95% CI, 1.0099-2.1125; P = .0442], and the value of insulin resistance index (homeostatic model assessment for insulin resistance) at the time of KT [odds ratio, 2.5183; 95% CI, 1.7119-3.4692; P < .0001] represented predictive factors of PTDM. The independent risk factors of PTDM in our group were age at the time of KT of more than 60 years [HR 0.3871; 95% CI 0.1659-1.7767; P = .0281], waist circumference at the time of KT in men more than 94 cm and in women more than 80 cm [HR, 3.4833; 95% CI, 1.2789-9.4878 (P = .0146)], BMI at the time of KT [HR 3.0011; 95% CI 1.0725-8.3977 (P = .0363)], and triacylglycerols at the time of KT more than 1.7 mmol/L [HR, 2.9763; 95% CI, 1.0141-8.7352; P = .0471]. CONCLUSIONS: In the group of Slovak patients after kidney transplantation, the dominating risk factor for PTDM development was insulin resistance prior to KT.
