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.

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.

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.

PURPOSE OF THE STUDY The aim of this study was to evaluate the mid-term outcomes of the surgical reconstruction of Charcot Foot Neuroarthropathy in diabetic patients with failed conservative treatment and indicated for a below-knee amputation. MATERIAL AND METHODS In the period from 2010 to 2015 the surgical reconstruction of inactive, chronic Charcot Foot Neuroarthropathy classified as type II and III by Sanders and Frykbeg was performed in 16 patients with failed conservative treatment. All these patients were by the diabetes centres initially indicated for a below-knee amputation. The performed evaluation focused on the clinical outcome (limb preservation, walking in footwear, full weight-bearing capability, the radiographic result (talar-first metatarsal angle, calcaneal inclination - negative, neutral, positive), complications (associated and not associated with the surgery). RESULTS The mean follow-up period was 4.7 years (2.5-7.5 years). From the original group of 16 patients indicated for a below-knee amputation following the failure of conservative treatment, the amputation was performed in one patient only. After the surgical reconstruction 15 patients were able to fully weight-bear when achieving plantigrade foot position, of whom 9 wore regular footwear and 6 customised diabetic footwear. The talar-first metatarsal angle was corrected from the mean 30 degrees (20-45) to the mean 5 degrees (0-10). The calcaneal inclination was corrected from the negative preoperative value in all the cases to neutral in 5 patients and positive in 10 patients. The surgery-associated complications were the following: infectious complications - positive preoperative cultivation in 10 out of 16 patients, secondary healing of the surgical wound in 7 patients, the need of additional ablation of plantar prominence of tarsal skeleton in 2 patients, screw prominence in 2 patients with the need of extraction - all healed without complications. In one case a lower limb amputation was performed due to secondary limb ischemia. The complications not associated with the surgery consisted of a soft tissue injury due to neuropathy. DISCUSSION Conservative treatment remains the basic approach to Charcot foot neuroarthropathy which is often associated with a long-term off-loading of the affected limb on a wheelchair, repeated hospital stays, changes of wound dressing of plantar ulcers. These are stated as the most frequent indications for a major amputation. Nonetheless, even the major amputation is accompanied by complications. The candidate for a reconstruction surgery should be a cooperating, compensated, informed diabetic patient with Charcot foot neuroarthropathy, either instable or stable, but non-plantigrade. It is necessary to diagnose and treat the impairment of leg blood supply and osteomyelitis, and to provide an appropriate rehabilitation. CONCLUSIONS Of the original 16 indications for a lower limb amputation in diabetic patients with Charcot foot neuroarthropathy, only one amputation was performed. Positive mid-term outcomes of surgical reconstruction justify further development of this method, bearing in mind the necessity of careful indication and preoperative preparation of the patient in cooperation with diabetologists. Precise and accurate surgical technique and relevant postoperative care are essential to minimise the potential complications. Key words:Charcot arthropathy, diabetic neuropathy, rocker - bottom foot deformity, foot reconstruction.

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.

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.

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.

INTRODUCTION: Information about the incidence of organ-affecting complications of diabetes, including the diabetic foot syndrome, can be obtained from the documents of the Institute of Health Information in the Czech Republic. GOAL: Assessment of the development of high amputations and minor surgical procedures on the lower limb from 2010 to 2014 in a representative sample of the population of patients with DM kept in the General Health Insurance Company of the Czech Republic database. METHODOLOGY: We identified all individuals in the VZP database who had a record of DM diagnosis (E10-E16 based on ICD 10) or any antidiabetic therapy prescribed (ATC group A10) in the period of 2010-2014. A set of patients who had an agent from A10 group prescribed at least once in the given year was extracted for analysis. In the next step we identified individuals, who in the period of 2010-2014 also underwent a surgical procedure on the lower limb due to diabetic foot. RESULTS: An absolute number of lower limb amputations remains at a stationary level. CONCLUSION: The submitted analysis presents the first assessment of the development of surgical treatment of diabetic foot in the Czech Republic. The amount of surgical procedures on the diabetic foot remains stable, regarding both high amputations and lower limb minor surgical procedures. In the context of an absolute increase of patients treated for diabetes mellitus, the stationary state is an indication of a relative decrease, which is favourable in particular with regard to the amputation of long bones.

OBJECTIVE: Infection commonly complicates diabetic foot ulcers and is associated with a poor outcome. In a cohort of individuals with an infected diabetic foot ulcer, we aimed to determine independent predictors of lower-extremity amputation and the predictive value for amputation of the International Working Group on the Diabetic Foot (IWGDF) classification system and to develop a risk score for predicting amputation. RESEARCH DESIGN AND METHODS: We prospectively studied 575 patients with an infected diabetic foot ulcer presenting to 1 of 14 diabetic foot clinics in 10 European countries. RESULTS: Among these patients, 159 (28%) underwent an amputation. Independent risk factors for amputation were as follows: periwound edema, foul smell, (non)purulent exudate, deep ulcer, positive probe-to-bone test, pretibial edema, fever, and elevated C-reactive protein. Increasing IWGDF severity of infection also independently predicted amputation. We developed a risk score for any amputation and for amputations excluding the lesser toes (including the variables sex, pain on palpation, periwound edema, ulcer size, ulcer depth, and peripheral arterial disease) that predicted amputation better than the IWGDF system (area under the ROC curves 0.80, 0.78, and 0.67, respectively). CONCLUSIONS: For individuals with an infected diabetic foot ulcer, we identified independent predictors of amputation, validated the prognostic value of the IWGDF classification system, and developed a new risk score for amputation that can be readily used in daily clinical practice. Our risk score may have better prognostic accuracy than the IWGDF system, the only currently available system, but our findings need to be validated in other cohorts.

Type 2 diabetes incidence is growing worldwide. It is in up to 50% cases linked with diabetic foot syndrome. This is associated with peripheral neuropathy and peripheral artery disease which increases risk of defects with impaired healing. Resulting high number of amputations has major influence on the quality of life and constitutes serious clinical issue. In recent years numerous clinical studies have shown positive effect of new treatment modality using regenerative potential of the autologous stem cells transplantation. This review tries to summarize existing results of therapeutic revascularization using stem cell and to outline mechanism of their action.
