[Spondylodiscitis and epidural empyema as a complication of diabetic foot]. / Spondylodiscitida, epidurální empyém jako komplikace syndromu diabetické nohy.

UNLABELLED: Spinal column infection (vertebral osteomyelitis, discitis, epidural empyema/ abscess) is a rare condition, albeit its incidence has been increasing in recent years. Staphylococcus aureus is the most frequent pathogen. The routes of infection are predominantly hematogenous. Any delay in making correct diagnosis increases risk of adverse outcome of the patient. The authors present 3 case reports of patients with diabetic foot syndrome, who were diagnosed with spondylodicitis in the period of 2009- 2012, two patients had associated epidural empyema. Apart of a chronic neuropathic foot wound, the patients reported severe or deteriorated dorsal pain (2 in the lumbal region, one in thoracic spine), had no new neurologic lesion in the beginning, some had fever, but all had high laboratory parameters of inflammation that did not correlate with local finding on the foot. Methicillin sensitive Staphylococcus aureus cultured from the foot defect in all cases, in two patients from blood cultures and from epidural empyema. They were patients with recurrent local infectious complications of diabetic foot ulcers. Two patients had a concomitant diabetic nephropathy, classified into stages 3- 4/ 5 according to K/ DOQI. Glycemic control (Type 1, Type 2 and secondary DM) ranged from excellent to unsatisfactory (HbA1c 43- 100 mmol/ mol). Apart of patient history and clinical examination, the magnetic resonance imaging of the spine was essential for the diagnosis of spondylodiscitis, or epidural empyema. The treatment was founded on longterm (initially parenteral) antibiotic treatment, bed rest, then mobilization with orthosis. Neurosurgical procedure was necessary in the patients with epidural empyema. All patients were mobile following a varied time period of convalescence and rehabilitation. CONCLUSION: Dorsal pain and degenerative changes of the spinal column belong to common findings in our population. When searching for the origin of an infection in patients with elevated inflammatory parameters (inadequate finding for a diabetic ulcer), the history of dorsal pain suddenly becomes the fundamental clue for diagnosis of spondylodiscitis with or without epidural empyema.

[Changes in weight and diabetes compensation (HbA1c) in patients with diabetes mellitus type 2 after adding exenatide (Byetta) to the current treatment in 28 diabetology departments in the Czech Republic -  BIBYII study (observations lasting 24 months)]. / Zmeny hmotnosti a kompenzace diabetu (HbA1c) u nemocných s diabetes mellitus 2. typu po pridání exenatidu (Byetta) ke stávající lécbe ve 28 diabetologických ambulancích v CR -  studie BIBYII (sledování 24 mesícu).

UNLABELLED: BIBYII STUDY OBJECTIVE: To obtain experience with longterm (24 months) exenatide treatment (Byetta) in patients with diabetes mellitus type 2 from a common clinical practice of diabetology departments in the Czech Republic. TYPE OF OBSERVATION: Observational study conducted by a randomly selected group of outpatient medical practitioners from 28 diabetology departments in the Czech Republic. OBSERVED AND ASSESSED POPULATION: From the original population of 465 patients, who underwent a minimum of three months Byetta treatment, 169 patients (36.6%) remained during the second prolonged observation after 18 months, and 76 patients completed 24 months of uninterrupted Byetta treatment. The following basic information about the patients was collected: year of birth, sex, age when diabetes mellitus (DM) manifested, height, maximum weight before diabetes and when DM manifested. The study recorded the following values in three- month intervals: weight, waistline, glycated haemoglobin (HbA1c), and DM treatment. The population of the prolonged observation comprised 50.3% women and 49.7 % men, and the average age at the time of DM2 manifestation was 48.0 (20- 73 years). RESULTS: At the beginning of Byetta treatment, the average maximum BMI in the subpopulation observed for 24 months was 38.44; after 3, 6, 9, 12 and 24 months the following levels were measured, respectively: 36.79, 36.22, 35.91, 35.57 and 35.58. The original HbA1c level of 7.44% at the beginning of Byetta treatment decreased after 3, 6, 9, 12 and 24 months to 6.33, 5.98, 5.83, 5.86 and 5.93%. CONCLUSION: Adding Byetta to the currently applied treatment of obese patients with diabetes mellitus type 2 over a period of 24 months has led to an improvement in HbA1c level by 1.51%, and BMI level was reduced by 2.37 after two years of Byetta treatment.

[Changes in weight and diabetes compensation (HbA(1c)) in patients with diabetes mellitus type 2 after adding exenatide (Byetta) to the current treatment in 28 diabetology departments in the Czech Republic - BIBY-I study (observations lasting 3 to 12 months)]. / Zmeny hmotnosti a kompenzace diabetu (HbA(1c)) u nemocných s diabetes mellitus 2. tpu po pridání exenatidu (Byetta) ke stávající lécbe ve 28 diabetologických ambulancích v CR--studie BIBY-I (sledováni 3-12 mesícu).

UNLABELLED: BIBY STUDY OBJECTIVE: To obtain experience with exenatide treatment (Byetta) in patients with diabetes mellitus type 2 in a common clinical practice ofdiabetology departments. TYPE OF OBSERVATION: Observational study conducted by a randomly selected group of outpatient medical practitioners from 28 diabetology departments in the Czech Republic. OBSERVED AND ASSESSED POPULATION: 465 patients underwent at least three months of Byetta treatment; 347 persons (74.6% ofthe research population) stayed forthe extended observation of 6-12 months. Apart from the basic identification data (year of birth, sex, age when diabetes mellitus manifested, height, maximum patient weight before diabetes and when diabetes mellitus manifested), the following information was recorded in three-month intervals: weight, waistline, glycated haemoglobin (HbA(1c)), and diabetes mellitus treatment The population included 50.3% women and 49.7% men, and the average age at the time of diabetes manifestation was 48 (20-73 years). The period between the diabetes manifestation and the start of exenatide treatment was 8.3 years on average. RESULTS: The average maximum BMI value before the detection of diabetes was 39.05 (+/- 6.73); at the time of the diabetes manifestation 37.88 (+/- 6.40); and at the start of Byetta treatment 39.01 (+/- 6.22). The BMI after three, six, and 12 months of treatment was as follows: 37.86 (+/- 6.12), 37.18 (+/- 6.0), and 36.60 (+/- 6.21); it decreased by > or = 0.5 in 83.3% patients who were under observation for 12 months. HbA(1c) value decreased in the first three months from 7.39% (+/- 1.57) to 6.41% (+/- 1.34), p < 0.0001. In the period of three-six months, the value decreased to 6.22% (+/- 1.34), and after 12 months, HbA(1c) was at 6.04 (+/- 1.20). An improvement in HbA(1c) value of 0.5-2.0% occurred after the first year in 49% of our research population. The waistline was measured on a regular basis in only 267 patients (58.9%). The average initial value of 120.7 cm was reduced within three months of the treatment to 118.3 cm, and within six and 12 months to 117.3 and 112.6 cm respectively. CONCLUSION: Adding Byetta to the currently applied treatment of obese patients with diabetes mellitus type 2 led, in 66.8% of the population, to a statistically significant reduction in HbA(1c) levels in the first three-six months of the treatment; after 12 months of treatment, 25% of the population was still showing an improvement in HbA(1c) of > 2.0%. Of observed patients, 74.4% significantly reduced their BMI (by > 0.5) during the first three months; 39.6% of patients reduced their BMI in the period of three-six months.

Analysis of continuous patient data from the Czech National Register of patients with type 1 and type 2 diabetes using insulin pump therapy.

AIM: Patient data from the Czech National Register of patients treated with Continuous Subcutaneous Insulin Infusion (CSII) were evaluated to compare treatment indication, efficacy and safety with specific regard to the type of diabetes (T1 vs. T2). METHODS: Evaluation was done on complete data sets of at least 3 years from patients with either T1 diabetes (n=730, 93.1%) or T2 diabetes (n=54, 6.9%) between 1995 and 2006. RESULTS: HbA(1c) decreased from 9.65 (+/-0.07) and 9.66 (+/-0.05) for T1 and T2 respectively to 8.24 (+/-0.07) for T1 and 8.52 (+/-0.27) for T2 after 1 year of treatment, 8.34 (+/-0.07) and 8.54 (+/-0.26) after 2 years and 8.44 (+/-0.07) and 8.71 (+/-0.25) after 3 years (adjusted mean values, +/-SEM). This reduction is significant for both diabetes types. Results gathered from the safety analysis revealed almost comparable results for both patient groups (rates of adverse events of 42.5 and 34.8 for T1 and T2, per 100 patients and year). CONCLUSION: Both patient groups achieved substantial reduction of HbA(1c). Safety evaluation showed that fewer patients with T2 diabetes were affected by adverse events. According to that CSII treatment for patients with T2 diabetes is similarly effective with a slightly better safety profile.

[Long-term evaluation of patients with type 1 diabetes mellitus treated with insulin glargine]. / Dlouhodobé sledování pacientu s diabetes mellitus 1. typu lécených inzulinem glargin.

AIMS OF THE STUDY: To evaluate long-term effects of treatment with insulin analogue glargine in patients with type 1 diabetes mellitus and to follow up their further course of life. PATIENT SAMPLE AND METHODOLOGY: Retrospective evaluation of 114 patients who, from September 2004, had their basal insulin changed from NPH insulin to insulin glargine. Treatment was changed again in patients in whom a year-long treatment with insulin glargine did not bring improvement in diabetes control. The original sample was divided into 3 groups and the results compared. Compensation of diabetes (HbA1c) after 1, 2 and 3 years and changes to basal and bolus daily insulin dose and body weight were evaluated. RESULTS: The results are presented as median and 25th and 75th percentile. Group A--75 patients (65%) treated for the entire evaluation period with insulin glargine. Initial HbA1c was 7.3 (6.4-8.2)%, 6.9 (6.0-8.4)% after 1 year, 7.1 (5.9-7.9)% after 2 years and 6.6 (5.5-7.7)% after 3 years (p < 0.001). We did not identify any statistically significant changes to total, basal or bolus daily dose of insulin or statistically significant body weight increase over the evaluation period. Group B--19 patients (17%). Switch from insulin glargine to detemir twice daily. Initial HbA1c was 7.3 (6.9-8.5)%, 7.4 (6.8-8.7)% after 1 year of treatment with insulin glargine, 7.7 (7.2-8.1)% before the treatment switch and 7.8 (6.7-8.5)% (NS) after 3 years of treatment. Daily dose of total, basal and bolus insulin did not change and, similarly, no statistically significant change to patients' bodyweight was identified. Group C--17 patients (15%). Switch from insulin glargine to an insulin pump. This group had better initial compensation with HbA1c 6.7(5.7-8.6)%, HbA1c after 1 year was 6.2 (5.6-8.1)%, 7.0 (6.0-7.4)% before the treatment switch and 6.3 (5.2-7.7)% after 3 years of treatment. Total daily insulin dose: 48 (34-60)-38 (25-49) IU/day (NS). Basal daily insulin dose: 17.5 (13-28) IU/day-23 (12-32) IU/day (NS). Bolus daily dose decreased significantly: from 25.5 (21-33) to 15.5 (12-22) IU/day (p < 0.01). Body weight: 76 (71-97) kg-73 (72-99) kg (NS). Only 3% of patients went back to NPH insulin. CONCLUSION: Insulin glargine brings improved control of diabetes. The dose of insulin glargine did not differ from NPH insulin. No statistically significant body weight increase was observed during the evaluation period.

[Glycated haemoglobin--is it its exclusive position in diabetology under threat?]. / Glykovaný hemoglobin. Je ohrozeno jeho výsostné postavení v diabetologii?

Hyperglycaemia is the common characteristic for diabetes patients. Prolonged hyperglycaemia due to absolute or relative lack of insulin is the cause of microangiopathy. Glucose reacts with both blood vessel wall proteins and plasmatic proteins and erythrocyte haemoglobin. This characteristic of glucose is used to monitor the level of diabetes compensation. The level of glycated haemoglobin reflects glycaemia for the last 2 to 3 months. It began to be used in diabetology in the 1980's. This outline paper deals with some of the pitfalls with which glycated haemoglobin has been recently associated. The first part is dedicated to factors influencing haemoglobin glycation. The second, methodological part focuses on factors influencing its assessment and interpretation. The third part concentrates on the options for the substitution ofglycated haemoglobin by other diabetes compensation markers.

[Clinical experience in treatment with the long-term insulin analogue glargin in a diabetes centre]. / Klinické zkusenosti s lécbou diouhodobým inzulinovým analogem glargin v diabetologickém centru.

OBJECTIVE: To assess the experience obtained by a diabetes centre in the treatment of patients with type 1 diabetes with the long-term insulin analogue glargin. PATIENT SAMPLE AND METHOD: 136 patients with type 1 diabetes mellitus (DM) were evaluated on a retrospective basis for the period from March 2004 to march 2005. We monitored HbA(1c) before the treatment with glargin, after 3 months, again after 6 months, and finally after 1 year of therapy. We evaluated the effectiveness of treatment with glargin insulin based upon diabetes compensation at the start of treatment. We also compared glycaemia variability in the 6 months prior to treatment initiation and the 6 months after the application of glargin insulin, this was done using the standard glycaemia deviation obtained from the patients' glucometers. In addition we evaluated the changes in total, basal and bolus daily dose of insulin after the change in therapy. RESULTS: The results were evaluated in the form of a median and the percentile of 25 and 75. Before the glargin therapy started, HbA(1c) was 7.4 (6.5-8.5)%. It decreased dramatically to 7.0 (6.2-8.1)% after 3 months of therapy (p < 0.01), to 7.2 (6.3-8.2)% after 6 months of therapy (p < 0.05), and reached the level of 7.1 (6.1-8.2)% after one year (p < 0.01). Analysis of glycemic profiles during the 6 months before and 6 months after transfer to glargin insulin therapy showed a significant decrease in the variability as evaluated by the decrease in standard deviations from the original 4.9 (4.3-5.6) mmol/l to 4.5 (3.9-5.1) mmol/l (p < 0.001). The total daily dose of insulin prior to treatment and after 6 months of therapy with glargin decreased from 44 (35-56) IU/day to 42 (34-53) IU/day (p = 0.01). There was no change in the basal dose of insulin after the change in therapy--it remained at 20 (12-28), (16-26) IU/day. The dose of bolus administered insulin decreased from 24 (18-32) to 21 (17-29) IU/day (p < 0.01). CONCLUSION: A dramatic improvement in HbA(lC) and a dramatic decrease in glycaemia variability are associated with glargin insulin treatment. The dose ofglargin insulin does not differ from that of NPH.
