Abstract
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.

Abstract
Diabetes mellitus is a chronic disease affecting glucose metabolism. The pathophysiological reactions underpinning the disease can lead to the development of late diabetes complications. The gut microbiota plays important roles in weight regulation and the maintenance of a healthy digestive system. Obesity, diabetes mellitus, diabetic retinopathy, diabetic nephropathy and diabetic neuropathy are all associated with a microbial imbalance in the gut. Modern technical equipment and advanced diagnostic procedures, including xmolecular methods, are commonly used to detect both quantitative and qualitative changes in the gut microbiota. This review summarises collective knowledge on the role of the gut microbiota in both types of diabetes mellitus and their late complications, with a particular focus on diabetic foot syndrome.

Abstract
This current opinion article critically evaluates the efficacy of autologous cell therapy (ACT) for chronic limb-threatening ischemia (CLTI), especially in people with diabetes who are not candidates for standard revascularization. This treatment approach has been used in 'no-option' CLTI in the last two decades and more than 1700 patients have received ACT worldwide. Here we analyze the level of published evidence of ACT as well as our experience with this treatment method. Many studies have shown that ACT is safe and an effective method for patients with the most severe lower limb ischemia. However, some trials did not show any benefit of ACT, and there is some heterogeneity in the types of injected cells, route of administration and assessed endpoints. Nevertheless, we believe that ACT plays an important role in a comprehensive treatment of patients with diabetic foot and severe ischemia.

Abstract
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.

Abstract
Diabetic foot is a serious late complication frequently caused by infection and ischaemia. Both require prompt and aggressive treatment to avoid lower limb amputation. The effectiveness of peripheral arterial disease therapy can be easily verified using triplex ultrasound, ankle-brachial/toe-brachial index examination, or transcutaneous oxygen pressure. However, the success of infection treatment is difficult to establish in patients with diabetic foot. Intravenous systemic antibiotics are recommended for the treatment of infectious complications in patients with moderate or serious stages of infection. Antibiotic therapy should be initiated promptly and aggressively to achieve sufficient serum and peripheral antibiotic concentrations. Antibiotic serum levels are easily evaluated by pharmacokinetic assessment. However, antibiotic concentrations in peripheral tissues, especially in diabetic foot, are not routinely detectable. This review describes microdialysis techniques that have shown promise in determining antibiotic levels in the surroundings of diabetic foot lesions.

Abstract
Determination of the broad-spectrum antibiotics amoxicilline (AMX) and ceftazidime (CTZ) in blood serum and microdialysates of the subcutaneous tissue of the lower limbs is performed using CE with contactless conductivity detection (C4 D). Baseline separation of AMX is achieved in 0.5 M acetic acid as the background electrolyte and separation of CTZ in 3.2 M acetic acid with addition of 13% v/v methanol. The CE-C4 D determination is performed in a 25 µm capillary with suppression of the EOF using INST-coating on an effective length of 18 cm and the attained migration time is 4.2 min for AMX and 4.4 min for CTZ. The analysis was performed using 20 µl of serum and 15 µl of microdialysate, treated by the addition of acetonitrile in a ratio of 1/3 v/v and the sample is injected into the capillary using the large volume sample stacking technique. The LOQ attained in the microdialysate is 148 ng/ml for AMX and 339 ng/ml for CTZ, and in serum 143 ng/ml for AMX and 318 ng/ml for CTZ. The CE-C4 D method is employed for monitoring the passage of AMX and CTZ from the blood circulatory system into the subcutaneous tissue at the sites of diabetic ulceration in patients suffering from diabetic foot syndrome and also for measuring the pharmacokinetics following intravenous application of bolus antibiotic doses.

Abstract
BACKGROUND Autologous cell therapy (ACT) is a new treatment method for patients with diabetes and no-option chronic limb-threatening ischemia (NO-CLTI). We aimed to assess the impact of ACT on NO-CLTI in comparison with standard treatment (ST) in a randomized controlled trial. METHODS Diabetic patients with NO-CLTI were randomized to receive either ACT (n=21) or ST (n=19). After 12 weeks, those in the ST group, who did not improve were treated with ACT. The effect of ACT on ischemia and wound healing was assessed by changes in transcutaneous oxygen pressure (TcPO2) and the number of healed patients at 12 weeks. Pain was evaluated by Visual Analogue Scale (VAS). Amputation rates and amputation-free survival (AFS) were assessed in both groups. RESULTS During the first 12 weeks, TcPO2 increased in the ACT group from 20.8 ± 9.6 to 41.9 ± 18.3 mm Hg (p=0.005) whereas there was no change in the ST group (from 21.2 ± 11.4 to 23.9 ± 13.5 mm Hg). Difference in TcPO2 in the ACT group compared to ST group was 21.1 mm Hg (p=0.034) after 12 weeks. In the period from week 12 to week 24, when ST group received ACT, the TcPO2 in this group increased from 20.1 ± 13.9 to 41.9 ± 14.8 (p=0.005) while it did not change significantly in the ACT in this period. At 24 weeks, there was no significant difference in mean TcPO2 between the two groups. Wound healing was greater at 12 weeks in the ACT group compared to the ST group (5/16 vs. 0/13, p=0.048). Pain measured using VAS was reduced in the ACT group after 12 weeks compared to the baseline, and the difference in scores was again significant (p<0.001), but not in the ST group. There was no difference in rates of major amputation and AFS between ACT and ST groups at 12 weeks. CONCLUSIONS This study has showed that ACT treatment in patients with no-option CLTI and diabetic foot significantly improved limb ischemia and wound healing after 12 weeks compared to conservative standard therapy. Larger randomized controlled trials are needed to study the benefits of ACT in patients with NO-CLTI and diabetic foot disease. TRIAL REGISTRATION The trial was registered in the National Board of Health (EudraCT 2016-001397-15).

Abstract
OBJECTIVES Diabetic foot syndrome (DFS) is a serious late diabetic complication characterised by limited joint mobility and other biomechanical and muscle abnormalities. AIM To evaluate the effect of an interventional exercise programme on anthropometric parameters, muscle strength, mobility and fitness in patients with diabetic foot in remission. DATA SOURCES AND STUDY SELECTION Thirty-eight patients with type 2 diabetes and DFS without active lesions (mean age 65 ± 6.9 years, BMI 32 ± 4.7 kg.m-2, waist-hip ratio (WHR)1.02 ± 0.06) were enrolled in our randomised controlled trial. All subjects were randomised into two groups: an intervention group (I; n=19) and a control group (C; n=19). The 12-week exercise intervention focused on ankle and small-joint mobility in the foot, strengthening and stretching of the lower extremity muscles, and improvements in fitness. Changes (Δ=final minus initial results) in physical activity were assessed using the International Physical Activity Questionnaire (IPAQ), with joint mobility detected by goniometry, muscle strength by dynamometry, and fitness using the Senior Fitness Test (SFT). DATA EXTRACTION Due to reulceration, 15.8% of patients from group I (3/19) and 15.8% of patients from group C were excluded. Based on the IPAQ, group I was more active when it came to heavy (p=0.03) and moderate physical activity (p=0.06) after intervention compared to group C. Group I improved significantly in larger-joint flexibility (p=0.012) compared to controls. In group I, dynamometric parameters increased significantly in both lower limbs (left leg; p=0.013, right leg; p=0.043) compared to group C. We observed a positive trend in the improvement of fitness in group I compared to group C. We also confirmed positive correlations between heavy physical activity and selected parameters of flexibility (r=0.47; p=0.007), SFT (r=0.453; p=0.011) and dynamometry (r=0.58; p<0.0025). Anthropometric parameters, such as BMI and WHR, were not significantly influenced by the intervention programme. CONCLUSION Our 12-week interventional exercise programme proved relatively safe, resulting in improved body flexibility and increased muscle strength in DF patients in remission.

Abstract
UNLABELLED Scoring for the risk of Diabetic foot syndrome (DFS) should be performed regularly in each patient with diabetes mellitus (DM). Patients at risk for DFS should be followed by diabetologists, those with moderate and severe risk for the development of DFS or those with DFS in remission should be already followed by podiatrists. The aim of our study was to determine the extent of DFS risk screening procedures, dispensary care of patients at risk for DFS and treatment of patients with newly developed DFS in diabetes clinics in the Czech Republic. METHODS To find out the study data, we prepared in cooperation with the ČDS ČLS JEP Committee a questionnaire survey for outpatient diabetology specialists. RESULTS The questionnaire was completed by 57% (76/135) of diabetologists. Most of them dispensary approximately 1000- 2000 patients with DM. Their feet are checked by 98.7% of diabetologists (1.6 ± 0.8 times a year on average). Screening for the risk of DFS (13024) is performing in less than 100 patients by 74.3% of diabetologists, in 100-200 patients by 14.9% and in more than 200 patients by 10.8% of diabetologists. 77% of respondents are able to examine neuropathy, the rest send their patients to neurologists, peripheral arterial disease is evaluated by only 47.3% of diabetologists (35.3% of them use some form of instrumental examination), others (48.6%) send patients to angiologists, 4.1% of diabetologists do not examine PAD at all). Based on the assessed findings, more than half of the respondents (50.7%) perform scoring for the risk of DFS, but 1/5 of outpatient diabetologists do not know how the scoring is performed. If colleagues find a patient at a risk for DFS, they usually follow him/her by themselves (64.4%), in 24.6% of cases they send the patient immediately to podiatry or surgery (11%). If a patient with a new DFS comes at diabetology clinic, 72.6% of diabetologists are able to prescribe off-loading, 60.3% antibiotics, 47.9% local therapy. Only 52.1% of diabetologists send a patient with a new DFS to outpatient foot clinic, 39.7% to surgery, the rest of them elsewhere. CONCLUSION Based on the questionnaire survey results, the screening of DFS is currently severely undersized in outpatient diabetology clinics, it is sufficiently performed only by 11% of diabetologists. Only 16% of diabetologists perform some form of non-invasive diagnostic procedures detecting peripheral arterial disease, neuropathy examinations are more common. If a diabetologist meet a patient with newly developed DFS, he/she is able to prescribe off-loading or antibiotics, but only half of the diabetologists send the patient to outpatient foot clinic, probably due to a lack of them or their overload.

Abstract
Autologous cell therapy (ACT) is a new treatment for patients with no-option critical limb ischemia (NO-CLI). We evaluated the factors involved in the nonresponse to ACT in patients with CLI and diabetic foot. Diabetic patients (n = 72) with NO-CLI treated using ACT in our foot clinic over a period of 8 years were divided into responders (n = 57) and nonresponders (n = 15). Nonresponder was defined as an insufficient increase in transcutaneous oxygen pressure by <5 mm Hg, 3 months after ACT. Patient demographics, diabetes duration and treatment, and comorbidities as well as a cellular response to ACT, limb-related factors, and the presence of inherited thrombotic disorders were compared between the 2 groups. The main independent predictors for an impaired response to ACT were heterozygote Leiden mutation (OR 10.5; 95% CI, 1.72-4) and homozygote methylenetetrahydrofolate reductase (MTHFR 677) mutation (OR 3.36; 95% CI, 1.0-14.3) in stepwise logistic regression. Univariate analysis showed that lower mean protein C levels (P = .041) were present in nonresponders compared with responders. In conclusion, the significant predictors of an impaired response to ACT in diabetic patients with NO-CLI were inherited thrombotic disorders.

Abstract
BACKGROUND All diagnostic procedures of peripheral arterial disease (PAD) in diabetic foot (DF) are complicated due to diabetes mellitus and its late complications.The aim of our study is to enhance diagnosis of PAD using a novel transcutaneous oximetry (TcPO2) stimulation test. METHODS The study comprised patients with mild-to-moderate PAD(WIfI-I 1 or 2) and baseline TcPO2 values of 30-50 mmHg.TcPO2 was measured across 107 different angiosomes. Stimulation examination involved a modification of the Ratschow test. All patients underwent PAD assessment (systolic blood pressures (SBP), toe pressures (TP), the ankle-brachial indexes (ABI) and toe-brachial indexes (TBI), duplex ultrasound of circulation). Angiosomes were divided into two groups based on ultrasound findings: group M(n=60) with monophasic flow; group T(n=47) with triphasic flow. Large vessel parameters and TcPO2 at rest and after exercise (minimal TcPO2, changes in TcPO2 from baseline (Δ,%), TcPO2 recovery time) measured during the stimulation test were compared between study groups. RESULTS During the TcPO2 stimulation exercise test, group M exhibited significantly lower minimal TcPO2 (26.2 ± 11.1 vs. 31.4 ± 9.4 mmHg; p<0.01), greater Δ and percentage decreases from resting TcPO2 (p=0.014 and p=0.007, respectively) and longer TcPO2 recovery times (446 ± 134 vs. 370 ± 81ms;p=0.0005) compared to group T. SBPs, TPs and indexes were significantly lower in group M compared to group T. Sensitivity and specificity of TcPO2 stimulation parameters during PAD detection increased significantly to the level of SBP, ABI, TP and TBI. CONCLUSION Compared to resting TcPO2, TcPO2 measured during stimulation improves detection of latent forms of PAD and restenosis/obliterations of previously treated arteries in diabetic foot patients.

Abstract
The care of patients with diabetic foot syndrome (DFS) requires interdisciplinary cooperation, and therefore interdisciplinary recommendations focused on the diagnosis and treatment and prevention of DFS are in place. We also need these recommendations because DFS has its own specifics that affect its diagnosis, therapy, but also the prognosis of patients. These include, for example, the different course of infection and PAD in patients with diabetes, the diagnosis of neuropathic Charcot osteoarthropathy, and the frequent association with end stage kidney disease, which worsens the course of SDN and increases its risk. Last but not least, the specifics of DFS include the issue of amputations with a significantly worse prognosis than in people without diabetes. The creation of an interdisciplinary team in foot clinics, providing comprehensive care for patients with DFS according to the recommended procedure, is associated with improved prognosis of patients with DFS, especially the reduction of amputations.

Abstract
Diabetic foot (DF) is a serious late complication of diabetes associated with high morbidity and mortality, often leading to lower limb amputation. Risk factors for DF include neuropathy, infection, and ischemia. The prevention of ulceration is essential for reducing amputation rate. Effective follow-up of patients and application of preventive approaches such as using of appropriate shoes and foot care can reduce the incidence of ulcerations by up to 50 %. DF treatment is very expensive and includes offloading of the affected foot, treatment of infection and revascularization. Local treatment and satisfactory diabetes control are also very important. Professional care for these patients should be directed to specialized podiatric clinics due to the need for a multidisciplinary approach.

Abstract
AIM To assess the impact of autologous cell therapy on critical limb ischaemia in people with diabetes and diabetic kidney disease. METHODS A total of 59 people with diabetes (type 1 or type 2) and critical limb ischaemia, persisting after standard revascularization, were treated with cell therapy in our foot clinic over 7 years; this group comprised 17 people with and 42 without severe diabetic kidney disease. The control group had the same inclusion criteria, but was treated conservatively and comprised 21 people with and 23 without severe diabetic kidney disease. Severe diabetic kidney disease was defined as chronic kidney disease stages 4-5 (GFR <30 ml/min/1.73 m²). Death and amputation-free survival were assessed during the 18-month follow-up; changes in transcutaneous oxygen pressure were evaluated at 6 and 12 months after cell therapy. RESULTS Transcutaneous oxygen pressure increased significantly in both groups receiving cell therapy compared to baseline (both P<0.01); no significant change in either of the control groups was observed. The cell therapy severe diabetic kidney disease group had a significantly longer amputation-free survival time compared to the severe diabetic kidney disease control group (hazard ratio 0.36, 95% CI 0.14-0.91; P=0.042); there was no difference in the non-severe diabetic kidney disease groups. The severe diabetic kidney disease control group had a tendency to have higher mortality (hazard ratio 2.82, 95% CI 0.81-9.80; P=0.062) than the non-severe diabetic kidney disease control group, but there was no difference between the severe diabetic kidney disease and non-severe diabetic kidney disease cell therapy groups. CONCLUSIONS The present study shows that autologous cell therapy in people with severe diabetic kidney disease significantly improved critical limb ischaemia and lengthened amputation-free survival in comparison with conservative treatment; however, the treatment did not influence overall survival.

Abstract
Autologous cell therapy (ACT) is a new treatment method for diabetic patients with critical limb ischemia (CLI) not eligible for standard revascularization. After intramuscular injection of bone marrow-derived mononuclear cells local arteriogenesis in the ischemic tissue occurs. Studies assessing visualization of this therapeutic vasculogenesis after ACT by novel imaging techniques are lacking. The aim of our study was to assess the effect of ACT on possible metabolic changes and perfusion of critically ischemic limbs using (31)P magnetic resonance spectroscopy ( (31)P MRS) and its possible correlation with changes of transcutaneous oxygen pressure (TcPO(2)). Twenty-one patients with diabetes and no-option CLI treated by ACT in our foot clinic over 8 years were included in the study. TcPO(2) as well as rest (phosphocreatine, adenosine triphosphate and inorganic phosphate) and dynamic (mitochondrial capacity and phosphocreatine recovery time) (31)P-MRS parameters were evaluated at baseline and 3 months after cell treatment. TcPO(2) increased significantly after 3 months compared with baseline (from 22.4±8.2 to 37.6±13.3 mm Hg, p=0.0002). Rest and dynamic (31)P MRS parameters were not significantly different after ACT in comparison with baseline values. Our study showed a significant increase of TcPO(2) on the dorsum of the foot after ACT. We did not observe any changes of rest or dynamic (31)P MRS parameters in the area of the proximal calf where the cell suspension has been injected into.

Abstract
Infections caused by Pseudomonas sp are difficult to resolve by antibiotics (ATBs) and local therapy. The aim of our pilot study was to assess the effect of different local agents-particularly acidifying solutions-on the healing of diabetic foot ulcers (DFUs), eradication of pathogens, and economic costs related to DFU therapy. In this case study, we monitored 32 DFU patients infected by Pseudomonas species. Patients were divided into 2 groups according to the local therapy provided: group 1 (n = 15)-modern local treatment; group 2 (n = 17)-acidifying antiseptic solutions. The study groups differed only with regard to ATB usage prior to enrolment in the study (P = .004), but did not differ with regard to age, diabetes control, peripheral arterial disease, or microcirculation status. During the follow-up period, DFUs healed in 20% of cases in group 1, but there were no cases of healing in group 2 (NS). The length of ATB therapy, the number of new osteomyelitis, lower limb amputations, and the changes of DFUs status/proportions did not differ significantly between study groups. Pseudomonas was eradicated in 67% of cases in group 1 and in 65% of cases in group 2. The local treatment given to group 2 patients was associated with lower costs (P < .0001). Conclusion. Acidifying agents had the same effect as modern healing agents on wound healing, the number of amputations, and the eradication of Pseudomonas. Moreover, therapy performed using acidifying solutions proved in our pilot study markedly cheaper.

Abstract
OBJECTIVE Off-loading is one of the crucial components of diabetic foot (DF) therapy. However, there remains a paucity of studies on the most suitable off-loading for DF patients under postoperative care. The aim of our study was to evaluate the effect of different protective off-loading devices on healing and postoperative complications in DF patients following limb preservation surgery. METHODS This observational study comprised 127 DF patients. All enrolled patients had undergone foot surgery and were off-loaded empirically as follows: wheelchair+removable contact splint (RCS) (group R: 29.2%), wheelchair only (group W: 48%), and wheelchair+removable prefabricated device (group WP: 22.8%). We compared the primary (e.g., the number of healed patients, healing time, and duration of antibiotic (ATB) therapy) and secondary outcomes (e.g., number of reamputations and number and duration of rehospitalizations) with regard to the operation regions across all study groups. RESULTS The lowest number of postoperative complications (number of reamputations: p = 0.028; rehospitalizations: p = 0.0085; and major amputations: p = 0.02) was in group R compared to groups W and WP. There was a strong trend toward a higher percentage of healed patients (78.4% vs. 55.7% and 65.5%; p = 0.068) over a shorter duration (13.7 vs. 16.5 and 20.3 weeks; p = 0.055) in the R group, as well. Furthermore, our subanalysis revealed better primary outcomes in patients operated in the midfoot and better secondary outcomes in patients after forefoot surgery-odds ratios favouring the R group included healing at 2.5 (95% CI, 1.04-6.15; p = 0.037), reamputations at 0.32 (95% CI, 0.12-0.84; p = 0.018), and rehospitalizations at 0.22 (95% CI, 0.08-0.58; p = 0.0013). CONCLUSIONS This observational study suggests that removable contact splint combined with a wheelchair is better than a wheelchair with or without removable off-loading device for accelerating wound healing after surgical procedures; it also minimises overall postoperative complications, reducing the number of reamputations by up to 77% and the number of rehospitalizations by up to 66%.

Abstract
AIM The standard method for assessment of effect of revascularization in patients with diabetic foot (DF) and critical limb ischemia (CLI) is transcutaneous oxygen pressure (TcPO2). Phosphorus magnetic resonance spectroscopy (31P MRS) enables to evaluate oxidative muscle metabolism that could be impaired in patients with diabetes and its complications. The aim of our study was to compare MRS of calf muscle between patients with DF and CLI and healthy controls and to evaluate the contribution of MRS in the assessment of the effect of revascularization. METHODS Thirty-four diabetic patients with DF and CLI treated either by autologous cell therapy (ACT; 15 patients) or percutaneous transluminal angioplasty (PTA; 12 patients) in our foot clinic during 2013-2016 and 19 healthy controls were included into the study. TcPO2 measurement was used as a standard method of non-invasive evaluation of limb ischemia. MRS examinations were performed using the whole-body 3T MR system 1 day before and 3 months after the procedure. Subjects were examined in a supine position with the coil fixed under the m. gastrocnemius. MRS parameters were obtained at rest and during the exercise period. Rest MRS parameters of oxidative muscle metabolism such as phosphocreatine (PCr), inorganic phosphate (Pi), phosphodiesters (PDE), adenosine triphosphate (ATP), dynamic MRS parameters such as recovery constant PCr (τPCr) and mitochondrial capacity (Qmax), and pH were compared between patients and healthy controls, and also before and 3 months after revascularization. RESULTS Patients with CLI had significantly lower PCr/Pi (p < 0.001), significantly higher Pi and pH (both p < 0.01), significantly lower Qmax and prolonged τPCr (both p < 0.001) in comparison with healthy controls. We observed a significant improvement in TcPO2 at 3 months after revascularization (from 26.4 ± 11.7 to 39.7 ± 17.7 mm Hg, p < 0.005). However, the rest MRS parameters did not change significantly after revascularization. In individual cases we observed improvement of dynamic MRS parameters. There was no correlation between MRS parameters and TcPO2 values. CONCLUSION Results of our study show impaired oxidative metabolism of calf muscles in patients with CLI in comparison with healthy controls. We observed an improvement in dynamic MRS parameters in individual cases; this finding should be verified in a large number of patients during longer follow-up.Key words: autologous cell therapy - critical limb ischemia - diabetic foot - MR spectroscopy.

Abstract
An electrophoretic stacking method has been developed for monitoring the therapeutic level of the antibiotic ceftazidime in blood plasma and microdialysates taken from peripheral soft tissues of the lower limbs of patients with diabetic foot syndrome. The biological samples are treated by addition of acetonitrile in an amount of 75% v/v and injected into a capillary in a large volume; after turning on the separation voltage, the residual acetonitrile is forced out of the capillary by the application of hydrodynamic pressure. The clinical samples were separated in an optimised background electrolyte composed of 50 mM chloroacetic acid +20% v/v methanol +0.5% v/v INST coating solution. The attained LOD for ceftazidime equalled 0.42 μg mL-1 (0.8 μM) and the migration time equalled 3.75 min when using a 25 μm capillary with minimum length of 31.5 cm. The separation was controlled by a maximum voltage of +30 kV and the movement of the analyte was accelerated by a pressure of 50 mbar. The RSD values for intra-day repeatability of the migration time and peak area are 0.14% and 3.8%, respectively; the inter-day values equalled 0.25% for the migration time and 7.3% for peak area, respectively. Pharmacological studies revealed that ceftazidime passes from the blood circulation to the peripheral tissues of the lower limbs with an efficiency of 20%. The introduction of CE control of ceftazidime level in diabetic foot represents a very important improvement in achieving the targeted therapeutic effect.

Abstract
INTRODUCTION One of the most serious complications of the diabetic foot (DF) is a major amputation, which is associated with poor patient prognosis. The occurrence of major amputations may be influenced by a variety of factors including deep infection caused by resistant pathogens.The aims of our study were to compare the incidence of major amputations in podiatric center, characteristics of amputated patients with the DF and other factors contributing to major amputations in last decade. METHODS We included into our study all patients hospitalized for the DF in our center whose underwent major amputations from 9/2004 to 9/2006 (group 1) and from 9/2013 to 9/2015 (group 2). Risk factors such as severity of DF ulcers based on Texas classification, duration of previous anti-biotic therapy, the presence and severity of peripheral arterial disease (PAD) according to Graziani classification, the number of revascularizations, renal failure/hemodialysis, osteomyelitis, infectious agents found before amputations and their resistance were compared between the study groups. RESULTS During the 1st study period (9/2004-9/2006) 373 patients were hospitalized for the DF, of whom 3.2 % underwent major amputation (12/373 - group 1), during the 2nd study period (9/2013-9/2015) 376 patients, of whom 5.1 % absolved major amputation (19/376 - group 2). As the numbers of major amputations as their indications were similar in both study groups. The study groups did not differ significantly in the age, BMI, duration and type of diabetes, duration of DF and severity of DF ulcers, the presence of renal failure/hemodialysis, osteomyelitis and PAD. Group 2 had milder forms of PAD by Graziani classification (4.4 ±1.4 vs 5.7 ± 0.9; p = 0.012) and a higher number of revascularizations before major amputations (2.5 ± 1.5 vs 1 ± 1; p = 0.003) compared to the group 1. These patients were significantly longer treated by antibiotics (5.4 ± 2.4 vs 2.5 ± 2 months; p = 0.002) and underwent more resections and minor amputations (3.1 ± 2.1 vs 0.9 ± 0.5; p = 0.0004) before major amputations in contrast to the group 1. There was a trend to higher incidence of Gram-negatives (65.1 % vs 61.5 %; NS) with a predominance of Enterobacteriacae species (60.7 % vs 56 %; NS) and a trend to the increase of Pseudomonas (25 % vs 18.8 %; NS) and Enterococci sp. (46.7 % vs 20 %; NS) in the group 2 compared to the group 1. The incidences as of MRSA, multidrug resistant Pseudomonas sp. of other resistant microbes were similar in both study groups. CONCLUSIONS The incidence of major amputations in patients hospitalized for the DF remains unchanged during the last decade. The therapy of factors leading to amputations has evidently intensified. This is in accordance with the latest international recommendations for the therapy of DF. In the future, it is appropriate to focus on the improvement of detection and treatment of infection and ischemia in such risk group of patients.Key words: diabetic foot - major amputation.

Abstract
UNLABELLED Adequate stabilization and off-loading of the lower limb is an integral part of postoperative care for patients with the diabetic foot. Off-loading can accelerate the healing process and reduce the number of complications and reoperations. The newly introduced method of the performance of removable contact splints (modified contact removable casts) seems to fulfil a number of requirements for stabilization and off-loading devices - the method is safe and can actually reduce the healing time and the number of reoperations in patients with the diabetic foot. KEY WORDS diabetic foot - off-loading - splints.

Abstract
The aim of our study was to analyse immune abnormalities in patients with chronic infected diabetic foot ulcers (DFUs) especially those infected by resistant microorganisms. Methods. 68 patients treated in our foot clinic for infected chronic DFUs with 34 matched diabetic controls were studied. Patients with infected DFUs were subdivided into two subgroups according to the antibiotic sensitivity of causal pathogen: subgroup S infected by sensitive (n = 50) and subgroup R by resistant pathogens (n = 18). Selected immunological markers were compared between the study groups and subgroups. Results. Patients with infected chronic DFUs had, in comparison with diabetic controls, significantly reduced percentages (p < 0.01) and total numbers of lymphocytes (p < 0.001) involving B lymphocytes (p < 0.01), CD4+ (p < 0.01), and CD8+ T cells (p < 0.01) and their naive and memory effector cells. Higher levels of IgG (p < 0.05) including IgG1 (p < 0.001) and IgG3 (p < 0.05) were found in patients with DFUs compared to diabetic controls. Serum levels of immunoglobulin subclasses IgG2 and IgG3 correlated negatively with metabolic control (p < 0.05). A trend towards an increased frequency of IgG2 deficiency was found in patients with DFUs compared to diabetic controls (22% versus 15%; NS). Subgroup R revealed lower levels of immunoglobulins, especially of IgG4 (p < 0.01) in contrast to patients infected by sensitive bacteria. The innate immunity did not differ significantly between the study groups. Conclusion. Our study showed changes mainly in the adaptive immune system represented by low levels of lymphocyte subpopulations and their memory effector cells, and also changes in humoral immunity in patients with DFUs, even those infected by resistant pathogens, in comparison with diabetic controls.

Abstract
The aim of our study was to analyse inherited thrombotic disorders that influence the long-term outcome of PTA. Methods. Diabetic patients with peripheral arterial disease (PAD) treated by PTA in our centre between 2008 and 2011 were included in the study. Patients were divided into unsuccessful PTA group (75 patients), successful PTA group (58 patients), and control group (65 patients, with diabetes but no PAD). Diagnosis of inherited thrombotic disorders included mutation in factor V (Leiden), factor II (prothrombin), and mutation in genes for methylenetetrahydrofolate reductase-MTHFR (C677T and A1298C). Results. The genotypic frequency of Leiden allele G1691A was significantly associated with a risk of unsuccessful PTA in comparison with successful PTA group and control group (OR 8.8 (1.1-70.6), p = 0.041, and OR 9.8 (1.2-79.2), p = 0.032, resp.). However, we only observed a trend for the association of the prothrombin allele G20210A and risk of PTA failure. The frequencies of alleles of MTHFR 677 or 1298 did not differ significantly among the groups. Conclusion. Our study showed higher frequency of heterozygous form of Leiden mutation in diabetic patients with unsuccessful outcome of PTA in comparison with patients with successful PTA and diabetic patients without PAD.

Abstract
UNLABELLED The aim of our case-control study was to compare selected psychological and social characteristics between diabetic patients with and without the DF (controls). METHODS 104 patients with and 48 without DF were included into our study. Both study groups were compared in terms of selected psychosocial characteristics. RESULTS Compared to controls, patients with DF had a significantly worse quality of life in the area of health and standard of living as shown by lower physical health domain (12.7 ± 2.8 versus 14.7 ± 2.5; P < 0.001) and environment domain (14.1 ± 2.2 versus 15 ± 1.8; P < 0.01) that negatively correlated with diabetes duration (r = -0.061; P = 0.003). Patients with DF subjectively felt more depressed in contrast to controls (24.5 versus 7.3%; P < 0.05); however, the depressive tuning was objectively proven in higher percentage in both study groups (83.2 versus 89.6; NS). We observed a significantly lower level of achieved education (P < 0.01), more patients with disability pensions (P < 0.01), and low self-support (P < 0.001) in patients with the DF compared to controls. In the subgroup of patients with a previous major amputation and DF (n = 6), there were significantly worse outcomes as in the environment domain (P < 0.01), employment status, and stress readaptation (P < 0.01) in contrast to the main study groups. CONCLUSIONS Patients with DF had a predominantly worse standard of living. In contrast to our expectations, patients with DF appeared to have good stress tolerability and mental health (with the exception of patients with previous major amputation) and did not reveal severe forms of depression or any associated consequences.

Abstract
AIM The aim of our study was to assess safety and effectiveness of therapy of critical limb ischaemia by autologous stem cells and evaluation of potential adverse events. METHODS Fourteen patients were included into the study (11 men, 3 women, mean age 61.9 +/- 9.6 years, mean diabetes duration 23.5 +/- 11.1 years, mean glycated hemoglobin 6 +/- 1%). Eight patients were treated by bone marrow stromal cells, 6 patients by peripheral blood progenitor cells after stimulation by filgrastim. The suspension of stem cells was then applied into the muscles of ischemic limbs. We evaluated transcutaneous oxygen tension (TcPO2), subjective pain sensation assessed by Visual Analog Scale (VAS) and wound healing. RESULTS TcPO2 significantly increased in all patients from 10 +/- 8.7 mm Hg before the treatment to 39.4 +/- 9.5 mm Hg after 6 months (p = 0.0005) after stem cell therapy. We also observed significant area defect reduction and pain decrease during the follow-up period. Median of area defect was reduced from 4.3 (0.7 - 31.7) before the treatment to 0.06 (0 - 0.5) cm2 after 6 months from the treatment (p = 0.0078). Decrease in rest pain was observed in all patients, mean VAS decreased from 5.3 +/- 1.8 to 1.1 +/- 1.3 after 6 months (p = 0.002). CONCLUSION Our study suggests that stem cell therapy of diabetic foot disease is an effective therapeutic option with no adverse events for patients with severe peripheral arterial disease. This treatment leads to increase of transcutaneous oxygen tension, improves wound healing and decreases the rest pain.

Abstract
Abnormal immune functions of polymorphonuclear (PMN) cells occur in a variety of pathophysiological conditions. There exists a close link between glucose metabolism and PMN functions. The aim of this study was to assess the effect of short-term hyperglycemia and/or hyperinsulinemia on phagocytosis and respiratory burst of PMN cells in healthy subjects in vivo. The study was performed on 12 healthy subjects (mean age, 26.9+/-1.6 years; body mass index, 24.4+/-0.84 kg/m(2)). Acute hyperglycemia and/or hyperinsulinemia was induced by three 4-hour-long clamp studies-hyperglycemic hyperinsulinemic clamp (HHC), hyperinsulinemic euglycemic clamp (HEC), and isolated hyperglycemic clamp with insulin secretion blockade (HGC). Polymorphonuclear cell phagocytosis and PMN cell respiratory burst (mean percentage and mean fluorescent intensity of phagocyting/activated PMN cells, phagocytic, and respiratory burst indexes) were evaluated by flow cytometry under basal and stimulated conditions. Results detected during clamp studies were compared with those found during a control study with saline infusion. Significant reductions in the mean percentage of phagocyting cells measured under basal conditions after the HHC (6.7%+/-1.3% vs 12.1%+/-4.3%; P<.05) and HGC (4.5% +/-1.8% vs 9.9%+/-2.1%; P<.05) were found in comparison with the pre-clamp study period; however, these results did not differ significantly from those detected during the control clamp (CC) study. Significantly higher phagocytic (115.1+/-65 vs 35.8 +/-18.6; P<.05) and respiratory burst indexes (16.5+/-3 vs 10.1+/-1.4; P<.05) measured under basal conditions were found after HEC in comparison with the pre-clamp data. However, these data did not differ significantly from those found after the CC study. No significant differences in other parameters of detected PMN cell immune functions were found after HHC, HEC, and HGC. In conclusion, immune functions of PMN cells were not significantly influenced by short-lasting hyperglycemia and/or hyperinsulinemia induced in vivo by clamp techniques in healthy subjects compared to changes induced by the CC study. Further studies on the short-term effect of glucose metabolism on PMN functions in diabetic patients should be considered necessary.

Abstract
AIM OF THE STUDY Individualized optimization of amoxicillin/clavulanate (AMC) antimicrobial therapy in diabetic foot infection. METHODS Pharmacokinetic analysis of individual steady-state plasma amoxicillin concentrations was done both in the i.v. infusion phase and in the oral phase of AMC, administered on the basis of the quantitative susceptibility of the detected microbe(s). The in vitro growth/killing dynamic parameters on model of Staphylococcus aureus as the most frequent isolate were evaluated. Therapeutic protocol optimization, leading to prediction of the earliest time to reduce the number of viable bacteria to 10-6 as a surrogate criterion of efficacy, was performed. RESULTS Based on individual plasma amoxicillin oscillations in 17 patients suffering from infected diabetic foot ulcers and the model microbial dynamic parameters, the reduction of the number of viable bacteria was reached significantly earlier after the administration of continuous i.v. AMC infusion than after the same daily AMC dose administered intermittently. In case of highly susceptible staphylococcal strain, highly frequent oral therapy of AMC (not longer than 8 hrs dosing interval) was also sufficiently effective. Decreasing plasma amoxicillin concentrations exponentially extended the time required for effective reduction of microbes. CONCLUSION Individualized optimization of amoxicillin/clavulanate dosage on the basis of growth/killing microbial dynamic parameters and antibiotic concentration/time fluctuations may enhance the antimicrobial effect and the treatment of infected non-critical ischemic diabetic foot ulcers.

Abstract
UNLABELLED Infectious complications of the diabetic foot may be influenced by impaired renal function and by immunosuppression therapy. AIMS To assess differences in microbial findings and resistance to antibiotics between transplant recipients, hemodialysis patients, and other patients with the diabetic foot. METHODS 207 patients treated in the foot clinic for diabetic ulcers from 12/1998 to 12/1999 were included into this retrospective study. Patients were divided into three groups (transplant, dialysis, and other patients). Occurrence of individual bacterial species and resistance to antibiotics was compared between study groups. RESULTS Study groups did not differ significantly in ulcer grades defined by the Wagner classification or in the mean number of pathogens per patient. The prevalence of individual microorganisms did not differ between the study groups. However, the study groups differed significantly in the occurrence of microbial resistance to antibiotics. Transplant patients had more frequently Staphylococcus aureus resistant to oxacillin (P<.01), imipenem (P<.01), co-trimoxazole (P<.01), Enterococcus species resistant to ampicillin (P<.01), piperacillin (P<.01), and dialysis patients had more frequently Pseudomonas species resistant to piperacillin (P<.05) and cefpirom (P<.05) in comparison with the other two groups. CONCLUSIONS Transplant patients had significantly more resistant microorganisms in comparison with dialysis and other patients with the diabetic foot. Empiric antibiotic selection based on general population data should be modified in transplant patients with diabetic foot according to actual susceptibility to antibacterial drugs.

Abstract
To address the question whether an increase in insulinemia and/or glycemia affects the total activity of lipoprotein lipase (LPL) in circulation, the enzyme activity was measured after periods of hyperinsulinemia (HI), hyperglycemia (HG), and combined hyperinsulinemia and hyperglycemia (HIHG) induced by euglycemic hyperglycemic clamp, hyperglycemic clamp with the infusion of somatostatin to inhibit endogenous insulin secretion, and hyperglycemic clamp, respectively. The results obtained were compared to those after saline infusion (C). Twelve healthy normolipidemic and non-obese men with normal glucose tolerance were included in the study. At the end of each clamp study, LPL activity was determined first in vivo using an intravenous fat tolerance test and then in vitro in postheparin plasma. Whereas isolated HI had no effect on LPL activity in postheparin plasma, both HG and HIHG reduced LPL activity to 60 % and 56 % of that observed after saline infusion. Similarly, the k2 rate constant determined in intravenous fat tolerance test was reduced to 95 %, 84 %, and 54 % after periods of HI, HG, and HIHG, respectively. The activity of hepatic lipase, another lipase involved in lipoprotein metabolism, was not affected by hyperinsulinemia and/or hyperglycemia. In conclusion, our data suggest that hyperglycemia per se can downregulate the total LPL activity in circulation.

Abstract
BACKGROUND Patients with diabetes represent 50 to 70% of patients who undergo nontraumatic foot or leg amputation, caused mostly by infection and necrosis of soft tissues accompanied with osteomyelitis. Signs and symptoms of infections may often be absent in patients with infected foot ulcers--the syndrome of "diabetic foot" (DF). The course and consequences of the infection may be influenced by the immune system dysfunction. The aim of our study was to assess presence of the chronic inflammation and specific immune responses, both humoral and cellular in patients with diabetic foot infection. METHODS AND RESULTS 34 patients treated over one month for an infected DF in our foot clinic (mean age 54 +/- 8 years, mean duration of diabetes 20 +/- 9 years, mean HbAlc 8.8 +/- 1.5%), were matched with 27 healthy subjects. All patients were without clinical signs of acute deep foot infection and without critical leg ischemia. The inflammatory response was assessed by white blood cells count and C-reactive protein (CRP), humoral immune response was assessed by immunoglobulins (Ig) and cellular immunity was evaluated by T lymphocytes subpopulations. Patients with DF compared with healthy controls exhibited the laboratory signs of infection--significantly increased white blood cells count (7.6 +/- 2.1 vs. 6.4 +/- 1.3.10(9)/l, p < 0.01) and neutrophil count (4.6 +/- 1.8 vs. 3.8 +/- 0.9.10(9)/l, p < 0.05) and significantly increased CRP (7 +/- 12 vs. 2 +/- 6 mg/l, p < 0.01). Patients with DF had also significantly higher IgA levels (3.5 +/- 1.6 vs. 2.7 +/- 1.1 g/l, p < 0.05) and significantly more CD3+ T cells (76 +/- 8 vs. 71 +/- 10%, p < 0.05) and suppressor/cytotoxic CD8+ T cells (32 +/- 11 vs. 26 +/- 10%, p < 0.05). Other followed parameters IgG, IgM and serum monocyte and lymphocyte counts, CD4+ helper T cells and CD4+/CD8+ T-cell ratio did not differ between patients with DF and healthy controls. CONCLUSIONS We did not anticipate a severe secondary immunodeficiency in followed cellular and humoral immune parameters in patients with chronic bacterial foot infection. It is necessary to assess the sufficiency of immune system activation with respect to chronic inflammation in next research.

Abstract
UNLABELLED Patients with diabetes mellitus undergo more amputations due to peripheral vascular disease, neuropathy and especially to infection requiring long-lasting antibiotic therapy than non diabetic patients. The aim of our study was to assess the association between the presence of resistant pathogens presented in diabetic ulcers and the frequency of lower limb amputations. METHODS 191 diabetic patients consecutively treated for the diabetic foot in our foot clinic were included into two years retrospective study. Peripheral ischemia, the presence of osteomyelitis and the incidence of all Gram positive and negative resistant pathogens (defined as resistance to all oral antibiotics) especially of resistant Staphylococcus species presenting in diabetic foot ulcers were determined. RESULTS 50/191 (26%) patients underwent amputation, of whom 44/50 (88%) had minor and 6/50 (12%) had major amputations. 53/181 (29%) patients with diabetic foot ulcers had resistant pathogens in their defects. Amputated patients had significantly more resistant microorganisms than patients without amputations--24/42 (57%) vs. 29/139 (21%); p < 0.001. Resistant Staphylococcus species were found in 21% (38/181) of all patients. Patients with amputations had significantly more resistant Staphylococcus species in comparison with patients without amputations--18/42 (43%) vs. 20/139 (14%); p < 0.001. Significantly higher incidence of peripheral vascular disease--79% (38/48) vs. 60% (81/136); p < 0.05 and osteomyelitis--69% (33/48) vs. 13% (18/140); p < 0.001--were found in patients with amputations in comparison with patients without amputations. CONCLUSION The presence of pathogens resistant to all oral antibiotics and especially of resistant Staphylococcus species was significantly higher in diabetic patients with lower limb amputations in comparison with patients without amputations.

Abstract
Chronic bacterial ulcers infection is a frequent cause of non-healing diabetic foot. The major factors of a non-specific immune response are phagocytic cells including polymporphonuclear (PMN) leukocytes, and humoral systems (complement). PMN leukocytes remove microorganisms by phagocytosis a part of it is intracellular killing and degradation in a process requiring energy and associated with "respiratory burst". The aim of our study was to assess non-specific immune response in patients with diabetic foot syndrome and chronic bacterial infection. 30 patients treated over one month with antibiotics for an infected diabetic foot in our foot clinic had significantly lower values of "oxidative burst" of PMN leukocytes in basal state (396 +/- 228 vs. 574 +/- 337, p < 0.05) in comparison with 25 matched healthy controls. There were no significant differences neither in the count of active phagocyting PMN leukocytes and their initial phagocytic activity nor in the humoral component of non-specific immunity (in circulating immunocomplexes, C3 and C4 components of complement) between both groups. The results of our study show a slightly altered non-specific immune response in patients with diabetic foot syndrome and chronic bacterial infection.
