Chronic Venous Disease and Its Intersections With Diabetes Mellitus.

Chronic venous disease (CVD) is a vascular disorder in which blood return is severely compromised and CVD is usually characterized by venous hypertension. Along with obesity and diabetes mellitus, CVD is one of the most common civilization diseases. In general, the estimated prevalence of CVD ranges from 60-80 %. Early diagnosis and adequate treatment are important for preventing progression to more severe stages of the disease like venous leg ulcers. Clinical manifestations of CVD in initial stages of the disease are often asymptomatic. However, as CVD progresses, symptoms begin to develop. Treatment of CVD could be divided into conservative and surgical. Conservative therapy consists of compression, pharmacological treatment and lifestyle change. In cases where conservative therapy is ineffective, surgical or endovascular treatment may be required. The intersections between diabetes mellitus (DM) and CVD are not to be underestimated. CVD and DM have often the same risk factors. Symptoms of CVD can be modified by late complications of DM, but the incidence of different CVD degrees seems to be the same as in diabetics as in non-diabetics population. We are particularly concerned in diabetics about worse compliance with treatment due to their often-poorer adherence to treatment of DM and lifestyle changes. Moreover, there exist a higher risk of CVD and peripheral arterial disease in diabetics patients. Patients with CVD should always be inspected for the presence of DM, considering its presence can have a bearing on CVD symptoms, diagnostic procedures, and therapeutic strategies.

Factors Influencing the Risk of Major Amputation in Patients with Diabetic Foot Ulcers Treated by Autologous Cell Therapy.

Introduction: Autologous cell therapy (ACT) is one of the last options for limb salvage in patients with chronic limb-threatening ischemia (CLTI) and diabetic foot ulcers (DFU). However, some patients may still undergo a major amputation even after ACT, but the risk factors for this are not known. Therefore, the aim of our study was to assess the risk factors for major amputation in patients with CLTI and DFU during a 2-year follow-up after ACT. Methods: One hundred and thirteen patients after ACT were included in our study and divided into two groups: Group 1 with major amputation (AMP; n = 37) and Group 2 without amputation (nAMP, n = 76). The risk factors for major amputation were evaluated before ACT and included factors relating to the patient, the DFU, and the cell product. Results: The AMP group had significantly higher C-reactive protein (CRP) levels compared to the nAMP group (22.7 vs. 10.7 mg/L, p = 0.024). In stepwise logistic regression, independent predictors for major amputation were mutation of the gene for methylenetetrahydrofolate reductase (MTHFR) with heterozygote and homozygote polymorphism 1298 (OR 4.33 [95% CI 1.05-17.6]), smoking (OR 3.83 [95% CI 1.18-12.5]), and CRP > 10 mg/L (OR 2.76 [95% CI 0.93-8.21]). Lower transcutaneous oxygen pressure (TcPO2) values were observed in AMP patients compared to the nAMP group at one month (24.5 vs. 33.2, p = 0.012) and at 3 months (31.1 vs. 40.9, p = 0.009) after ACT. Conclusion: Our study showed that the risk for major amputation after ACT in patients with CLTI and DFU is increased by the presence of MTHFR heterozygote and homozygote gene mutations, smoking, and higher CRP at baseline. Lower TcPO2 at one and 3 months after ACT may also have a predictive value. Therefore, it is necessary to stop smoking before ACT, treat any infection, and, above all, consider antiaggregation or anticoagulant treatment after the procedure.

Incidence and Risk Factors of Diabetic Foot Syndrome in Patients Early After Pancreas or Kidney/Pancreas Transplantation and its Association with Preventive Measures.

Diabetic foot (DF) can develop in diabetic patients after organ transplantation (Tx) due to several factors including peripheral arterial disease (PAD), diabetic neuropathy and inappropriate DF prevention. Aim: To assess the occurrence of DF and associated risk factors in transplant patients. Methods: Fifty-seven diabetic patients were enrolled as part of this prospective study. All patients underwent organ Tx (01/2013-12/2015) and were followed up for minimum of 12 months up to a maximum of 50 months. Over the study period we evaluated DF incidence and identified a number of factors likely to influence DF development, including organ function, presence of late complications, PAD, history of DF, levels of physical activity before and after Tx, patient education and standards of DF prevention. Results: Active DF developed in 31.6% (18/57) of patients after organ Tx within 11 months on average (10.7 ± 8 months). The following factors significantly correlated with DF development: diabetes control (p = .0065), PAD (p<0.0001), transcutaneous oxygen pressure (TcPO2;p = .01), history of DF (p = .0031), deformities (p = .0021) and increased leisure-time physical activity (LTPA) before Tx (p = .037). However, based on logistic stepwise regression analysis, the only factors significantly associated with DF during the post-transplant period were: PAD, deformities and increased LTPA. Education was provided to patients periodically (2.6 ± 2.5 times) during the observation period. Although 94.7% of patients regularly inspected their feet (4.5 ± 2.9 times/week), only 26.3% of transplant patients used appropriate footwear. Conclusions: Incidence of DF was relatively high, affecting almost 1/3 of pancreas and kidney/pancreas recipients. The predominant risk factors were: presence of PAD, foot deformities and higher LTPA before Tx. Therefore, we recommend a programme involving more detailed vascular and physical examinations and more intensive education focusing on physical activity and DF prevention in at-risk patients before transplantation.

The incidence and the characteristics of heart failure patients at a large medical department.

INTRODUCTION: Chronic heart failure (HF) has a prevalence of 6-10 % in patients above the age of 65 years, leading to high mortality, morbidity and re-hospitalization. AIM: To analyse the incidence and the characteristics of patients with HF in a medical department. PATIENTS AND METHODS: 941 patients (males 424, females 517 with an average age of 64 years and 67 years respectively), hospitalized from 1.9.1998 to 28.2.1999 at the 1st Internal Department of the University Hospital. A retrospective analysis of their files: age, diagnosis, duration of hospitalization, and in those patients with HF: the occurrence of risk factors and clinical events( stroke, myocardial infarction, and atrial fibrillation). RESULTS: We have analyzed the incidence of diseases at a medical department where 58.7 % of patients suffered from cardiovascular diseases. Patients with HF represented 13.9 % of all hospitalized patients. Among the risk factors dominated hypertension, diabetes, obesity, hyperlipidemia and smoking. The average duration of hospitalization was 12.66 days in men and 13.67 days in women. The hospitalization period was 15.6 days in hypertensive diabetic males whereas in females it was 15.3 days. These patients were hospitalized in their 5th decade with the incidence of HF increasing with age. Their mortality was 11.5 % while the overall mortality was 9.7 % among all patients hospitalized. Those patients who died suffered from poly-morbidity. CONCLUSION: The prevalence of HF in our patients was 13.9 %. This value is higher than the data from literature. These patients suffered from poly-morbidity (hypertension: 53-75 %, diabetes: 30 %, obesity: 33-38 %, hyperlipidemia: 20-50 %, smoking: 11-32 %, myocardial infarction: 41-50 %) and had a high mortality.
