ABSTRACT: Obesity in T1DM patients is associated with the components of metabolic syndrome. The influence of controlled fasting and low calorie diet (LCD) on insulin sensitivity and glucose metabolism was studied in 14 obese patients with type 1 diabetes mellitus (T1DM) (42.6+/-9.4 years, BMI 32.4+/-2.1 kg m(-2)). Insulin sensitivity in obese T1DM patients was measured using a hyperinsulinemic-euglycemic clamp before fasting, immediately after 7 days of fasting, and after 21 days of LCD. Glucose oxidation and non-oxidative glucose disposal were measured before and during the clamp by indirect calorimetry. In the control group of 13 of non-obese T1DM patients (36.9+/-13.9 years, BMI 22.6+/-2.1 kg m(-2)), only one hyperinsulinemic-euglycemic clamp was performed. Obese T1DM patients lost 6.1+/-1.1 kg after fasting and maintained reduction in body weight after 21 days of LCD. Fasting transiently reduced insulin-mediated glucose disposal in the clamp (from 9.69+/-1.48 to 6.78+/-1.21 mg min(-1) kg(-1), P<0.001). This was caused by reduced glucose oxidation after the fasting period (from 2.81+/-0.52 to 0.88+/-0.98 mg min(-1) kg(-1), P<0.001). We conclude that one week of fasting transiently decreased insulin-mediated glucose disposal in T1DM patients. This was caused by reduced glucose oxidation.

ABSTRACT: Using our statin analysis method, it was possible to uncover a significant drop in statin levels (atorvastatin, simvastatin, and metabolites) after extracorporeal LDL-cholesterol elimination (EE) in severe familial hypercholesterolemia (FH). The purpose of this work was to identify the mechanism underlying this drop and its clinical significance as well as to propose measures to optimize a pharmacotherapeutical regimen that can prevent the loss of statins.
Ultra High Performance Liquid Chromatography (UHPLC) connected to the triple quadrupole MS/MS system was used. Patients. A group of long-term treated patients (3-12 years of treatment) with severe FH (12 patients) and treated regularly by LDL-apheresis (immunoadsorption) or haemorheopheresis (cascade filtration) were included in this study.
After EE, the level of statins and their metabolites decreased (atorvastatin before/after LDL-apheresis: 8.83/3.46 nmol/l; before/after haemorheopheresis: 37.02/18.94 nmol/l). A specific loss was found (concentration of atorvastatin for LDL-apheresis/haemorheopheresis: 0.28/3.04 nmol/l in washing fluids; 11.07 nmol/l in filters). To prevent substantial loss of statin concentrations, a pharmacotherapeutic regimen with a longer time interval between the dose of statins and EE is recommended (15 hours).
A specific loss of statins was found in adsorbent columns and filters. The decrease can be prevented by the suggested dosage scheme.

ABSTRACT: The age related macular degeneration (ARMD) is the most common cause of practical blindness in the population older than 60 years of age. Usually it starts as a dry form with soft drusen.The progression of the dry form is difficult to control-promising seems to be the influence of rheologic factors in the choroid and the retina and thus improvement of their blood flow.
By means of haemorheopheresis to improve blood rheology and thus micocirculation in the choroid and retina. The authors describe the development of the dry form of the ARMD in the sensitive stage with soft drusen and the eventual presence of retinal pigment epithelium detachment (RPED) after haemorheopheresis. The treated patients were compared with a control group (natural course of the ARMD) with the same number of patients.
In a prospective, randomized study, comprising of 16 patients with the dry form of ARMD were treated with haemorheopheresis (cascade filtration) and 16 patients in the control group. Haemorheopheresis treatment comprised of 8 cycles in 10 weeks. Plasma obtained by separator was filtered by the Evaflux 4A (Japan) separator, where, the defined spectrum of high molecular proteins was captured. This lead to a decrease in blood and plasma viscosity and thus to improvement of rheologic conditions of the retina.
Results show a positive influence on the absorption of soft drusen, reduction of the retinal pigment epithelium detachment, and the possibility to improve the visual acuity of the treated patients.
Comparing to the worsening of clinical signs and visual functions in natural course of the ARMD development, the rheopheresis as well tolerated method may cause the retardation or stop of the unfavorable course of the disease.

ABSTRACT: Diabetes mellitus associates with high cardiovascular risk. The absolute values of cardiovascular risk tend to be even higher than as calculated from the SCORE tables. Recent randomized clinical trials have shown evidence of benefit and safety of more intensive LDL-cholesterol lowering in patients with diabetes and established cardiovascular disease supporting guidelines for a more intensive LDL goal of therapy. A recent meta-analysis has confirmed benefit on major coronary events and ischaemic stroke in many diabetic patient subgroups, including those with type 1 disease. The pathological combination of several lipoprotein metabolism abnormalities and the need to reach lipoprotein goals need combination therapy of hypolipidemic drugs with different mechanisms of action. Despite statin treatment, cardiovascular disease residual risk remains high. After LDL the next lipoprotein goal is to increase HDL. Although there has been disappointment with the first cholesteryl-ester-transfer-protein-inhibitor, there is encouraging evidence that increasing HDL with the peroxisome-proliferator-activator-receptor (PPAR) gamma agonist, pioglitazone and nicotinic acid derivatives may contribute beyond statin therapy.

ABSTRACT: Rheological conditions basically influence tissue perfusion, oxygen and nutrient supply, tissue regeneration and in its consequence the course of pathological processes, especially in microcirculation and partially even in macrocirculation. Haemorheotherapy has shown to be successful in several indications (critical disorders in microcirculation) when other methods of therapy have failed. In this study we describe the changes of effectivity indicators in haemorheopheresis treatment and their clinical importance in cases of eye microcirculation, statoacoustic apparatus and disorders of the lower extremities. We treated with haemorheopheresis (separator Cobe.Spetra + Evaflux filter) 24 patients (16 patients with age related macular degeneration, 5 with critical peripheral arterial foot disease, and 3 with acute hearing loss). After the procedures alpha2-macroglobulin decreases by about 58%, fibrinogen by about 69%, IgM by about 61%, LDL-cholesterol by about 77%, apolipoprotein B by about 76% and lipoprotein(a) by about 63%. It corresponds with a decrease in blood and plasma viscosity and clinical improvement in the observed patients, i.e. visual improvement, acceleration of tissue defect healing and improvement in hearing. We noticed 7.1% clinically insignificant side-effects. The method of haemorheopheresis was safe. It led to improvement in patients' clinical condition in the above mentioned indications when other methods of treatment failed.

ABSTRACT: Malnutrition is a major problem in chronically ill patients. The combination of diabetes and renal insufficiency increases the risk of malnutrition, also due to dietary interventions associated with the two diseases. Resulting malnutrition intensifies inflammatory activity and further compromises nutrition intake. This results in a vicious circle which significantly reduces the quality of life of the affected patients and increases their mortality. Proper nutritional care for such patients is an integral part of their treatment.

ABSTRACT: Immunoglobulin D (IgD) multiple myeloma (MM) is a rare plasma cell disorder constituting less than 2% of all MM cases. Survival of patients with IgD MM is generally shorter than that of patients with other types of monoclonal (M-) protein. We have retrospectively analyzed patients with IgD MM participating in clinical trials of the Czech Myeloma Group. Twenty-six IgD MM patients treated between 1996 and 2006 were identified, 14 (54%) men and 12 (46%) women. The median age was 61 years (range: 37-79 years). Ten of 26 patients (39%) were treated with first-line high-dose chemotherapy (HDCT) using melphalan 200 mg/m(2) followed by autologous stem cell transplantation (ASCT). Thirteen of 26 patients (50%) received conventional chemotherapy (CHT), mostly melphalan and prednisone or a vincristine/doxorubicin/dexamethasone (VAD) regimen. Treatment responses were evaluable for 23 of 26 (89%) patients. All HDCT patients had treatment responses, including seven patients (70%) with complete responses and three patients (30%) with partial responses. The median progression-free survival was 18 months for HDCT patients and 20 months for CHT patients. The median overall survival (OS) for all patients was 34 months. The median OS for the HDCT group has not yet been reached (70% of the patients are still alive). In contrast, the median OS for CHT patients was only 16 months. The difference in OS between the two groups was statistically significant (P=0.005). In conclusion, the overall response rate for patients with IgD MM aged 65 years or less treated with HDCT and ASCT is similar to that seen in other MM types.

ABSTRACT: Crohn's disease (CD) in its active period is accompanied by a decreased food intake and deterioration in water, mineral and metabolic balance. Lipid metabolism is known to be altered in many acute diseases, and hypocholesterolemia is a serious negative prognostic indicator. The causes of decreased serum cholesterol concentration are multiple. Simultaneous affection of both cholesterol synthesis and absorption has been reported in many sources. The changes in both the above processes can be quantified with the use of specific indicators of synthesis (cholesterol level) and absorption (sitosterol and campesterol levels).
The objective of the study was to demonstrate changes in lipid metabolism in patients with active Crohn's disease, and to find out to what extent the above phenomenon is influenced by the affection of the process of cholesterol synthesis and/or absorption in the case of detected hypocholesterolemia.
Total serum cholesterol, LDL- and HDL-cholesterol and triglyceride levels were measured on the 3rd, 14th and 28th day from admission in addition to admission analyses in 24 patients with acute manifestation of CD (CDAI - Cohn's disease activity index - over 150). Also measured were the concentrations ofsqualene, lathosterol, sitosterol and campesterol. The results were compared with a control sample of 100 voluntary blood donors. The obtained data was processed using the Sigma-stat 3.1 statistical software.
Decreased levels of all basic lipid metabolism parameters were detected. At the same time, a statistically significant decrease in the levels of lathosterol and camposterol was recorded. The decrease in sitosterol levels was insignificant and the level of squalene was higher than in the controls.
Significant changes in lipid metabolism were demonstrated in the study in patients in active phase of Crohn's disease. Also detected was statistically significant hypocholesterolemia, with altered process of cholesterol synthesis and absorption.

ABSTRACT: The number of patients with chronic renal failure is on the rise; these patients have a 10 to 20 times higher risk of development and progression of cardiovascular diseases. Higher cardiovascular risk in such patients cannot be satisfactorily explained by traditional risk factors defined in the Framingham study. On the contrary, a concept of reverse epidemiology has been brought forward, designating a situation in which the incidence of obesity and hyperlipoproteinemia is associated with a higher survival rate of the patients concerned. Higher risk is today explained by the "MIAC (malnutrition, inflammation, atherosclerosis, calcification) syndrome", which is present in patients with chronic kidney disease. New evidence has been recently obtained of different circulating molecules associated with atherosclerosis, the plasmatic levels of which are decreased or increased in such patients and which are in a way linked with the MIAC syndrome and the progression of atherosclerosis. Clinical management of the syndrome could increase survival in the future, and reduce morbidity and the number of hospitalisations. Circulating molecules could serve as markers evidencing the presence of the syndrome and its severity, as well as the success of treatment.

ABSTRACT: Switching of the paraprotein isotype or transient presence of oligoclonal bands detectable by serum immunofixation electrophoresis has been reported following not only transplantations, but also after intensive chemotherapy for leukemia. Retrospective analysis of 72 transplanted myeloma patients was carried out to determine the frequency and clinical significance of the appearance of abnormal proteins bands (APB) distinct from the original paraprotein. APB presence was observed in 31 patients (43%) already after the first autotransplant, the median interval from transplant was 2 months (range, 1 to 6 months). The most frequent occurrence of APB was observed after allogeneic transplantation. In the group of patients with APB presence more patients achieved complete remission (32.2% versus 17.1%), statistically significant differences were also established when we compared the percentage of surviving patients and overall survival, to the present date, among both groups of patients (p=0.03). All relapsed patients with previous isotype class switching had disease characterized by the same type of paraprotein as that detected at diagnosis. The development of APB is likely related to the recovery of impaired immunoglobulin production after transplantation. We confirmed favourable prognostic significance of this finding in transplanted myeloma patients.

ABSTRACT: The role of adhesive selectin molecules in the process of atherogenesis is an open question. These molecules are known as markers of atherosclerosis activity, however, only some biological mechanisms are known up to now. In this study we examined the levels of soluble forms of E-, P-selectin and monocyte chemotactic protein (MCP-1) in the process of extracorporeal cholesterol elimination by LDL-apheresis. We measured the levels of sE-, sP-selectin and MCP-1 in the plasma before and after LDL-apheresis and in the washout solution from immunoabsorption columns Lipopak. Eighty measurements were performed repeatedly in 6 patients with severe familial hypercholesterolemia (FH) on long-term LDL-apheresis treatment. Before the procedure P-selectin levels were 204+/-179 ng/ml, E-selectin 32.1+/-33.7 ng/ml, MCP-1 323.8+/-121 pg/l, whereas after the procedure we found P-selectin levels 131.6+/-34 ng/ml, E-selectin 33.1+/-51 ng/ml, and MCP-1 200.4+/-15 pg/l. Levels of P-selectin were increased in the blood of patients with FH in spite of long-term intensive extracorporeal LDL-elimination, documenting thus the activity of atherosclerosis. The levels of P-selectin and MCP-1 decreased significantly after the hypolidemic procedure and could be used as another marker showing the effectivity of the extracorporeal LDL-cholesterol elimination (immediately after the procedure), and, after further verification, may serve as a marker for controlling the therapy efficacy.

ABSTRACT: An acute operation was made on a 56-year woman for inflammatory perforation of colon. A series of repeated operations followed due to relapsing iatrogenic intestinal fistula and peritonitis. From the day 70 the patient was treated at the Intensive Metabolic Care Unit of the Gerontological and Metabolic Clinic of Faculty Hospital in Hradec Králové. Having cured the septic shock the authors prepared the patient to a reconstruction operation on alimentary tract by administering parenteral nutrition, treating the wounds and by motion rehabilitation. From day 150 on the patient was treated with low doses of enteral nutrition into the segment of intestine between the fistulas, in connection with the subsequent decrease of two-month lasting hyperbilirubinemia of 200-260 mumol/l. A successful reconstruction of the alimentary tract was performed on the day 205 of the treatment with the time lapse of 146 days after the last surgical intervention. A three-fold anastomosis on small intestine and a resection of the fistula on the transversal colon was made. The post-operation fistula was healed-up conservatively, while the parenteral nutrition continued, as verified on day 246 by enteroclysis. The paper draws attention to the importance of conservative metabolic care in the therapy of dishiscences of intestinal anastomoses not treated by acute surgery in time. A favourable additive effect of enteral nutrition on the persisting cholestasis during parenteral nutrition is discussed.

ABSTRACT: The aim of this randomised, double-blind, placebo controlled, parallel group study was to assess the effect of trimetazidine (TMZ), a potent antiischaemic drug, on plasma C-reactive protein (C-RP), cytokine and adhesion molecule levels. The study population consists of 18 patients (16 males, 2 females, average age 56.45 +/- 10.97 years) with acute myocardial infarction admitted within 6 hours after onset of symptoms and treated with streptokinase. Blood samples were taken at 3-hour intervals during the time of treatment. All patients were randomised blindly using a centralised randomisation process, between trimetazidine (40 mg bolus i.v. then 60 mg per day for 48 hours intravenously in glucose infusion) or placebo group. Plasma C-RP level was significantly lower in TMZ group (39.5 mg/ml +/- 9.7 mg/ml) as compared to placebo (75.7 +/- 29.4 mg/ml, p < or = 0.001) and peaked 28 hours later in TMZ group. Plasma interleukin 6 (IL 6) level showed a sharp peak 9 hours after the onset of the symptoms in TMZ group (116.9 +/- 180.2 pg/ml vs. 45.4 +/- 37.9 pg/ml) and was increased up to 30 hours after the onset of the symptoms. Plasma interleukin 1 beta (IL 1 beta) was also higher in TMZ group notably 21 hours after the onset of symptoms (26.4 +/- 9.3 pg/ml vs. 16.2 +/- 2.4 pg/ml). TMZ group showed lower plasma E-selectin levels. Plasma IL 8, TNF alpha and ICAM 1 levels were without statistical significant differences. The present study demonstrates a significant reduction of plasma C-reactive protein level in the course of acute myocardial infarction treated with streptokinase and intravenous trimetazidine infusion compared with the group of patients without trimetazidine treatment.

ABSTRACT: Dyslipoproteinaemia as one among classical risk factors of atherosclerotic cardiovascular diseases has been involved also in the aged. The predictive value of total cholesterol, LDL-cholesterol, HDL-cholesterol, triacylglycerols and lipoprotein (a) is preserved. There are several objective data from post-hoc analyses of prospective clinical studies AFCAPS/TexCAPS, 4S, CARE, LIPID a WOSCOPS, which addressed the need of treatment of dyslipoproteinaemia in the aged. The guidelines are not unique, but they stress an individual approach. We usually continue to treat genetic forms of dyslipidaemia. Candidates of treatment are also patients with diagnose of coronary heart disease (CHD) and sublinic form of CHD, where the treatment has been effective within two years and lead to decrease of CHD risk up to 45%. The individuals with CHD and other CHD risk factors absent would be treated less often. The diet is an basic treatment option of hypolipidemic intervention in the elderly. We do not omit exercise. The pharmacotherapy of dyslipidaemia is used for the individuals with high risk. We usually start with lower dose of fibrates or statins and monitor for adverse effects of such therapy.

ABSTRACT: To perform a longitudinal drug utilization evaluation and to analyse the antibiotic resistance patterns of Pseudomonas aeruginosa as well as the consumption of selected antibiotics.
Data from 1992-1997 were collected from the Hospital Pharmacy database at the University Teaching Hospital (1200 beds) where physicians' prescriptions are recorded. To analyse antibiotic consumption, ATC/DDD methodology was used. To express the dynamics of the drug consumption, the value of index I was established. To analyse the resistance patterns of Pseudomonas aeruginosa, data from the antibiotic centre database at The Teaching Hospital were examined.
The rate of consumption is on the rise among extend spectrum aminopenicillins, carbapenems, glycopeptides, third generation cephalosporins and second generation macrolides and fluoroquinolones. Antibiotics with a decline in the rate of consumption are first generation macrolides and tetracyclines.
The consumption of relatively new and expensive antibiotics increased during the observation period between 1992-1997. Resistance of Pseudomonas aeruginosa to selected antibiotics was identified to be increasing. In the case of amikacin and ceftazidime a possible association between resistance and consumption was found. Copyright (c) 2000 John Wiley & Sons, Ltd.

ABSTRACT: Twenty eight men (age 34-77 years) who underwent an elective coronary angiography for coronary artery disease (CAD), were studied. They were divided into group A (luminal narrowing < 50%; n = 11) and group B (luminal narrowing > 50%; n = 17). Capillary gas chromatography was used for determination of fatty acids. Retinol and alpha-tocopherol were analyzed by reversed-phase high-performance liquid chromatography (HPLC), other parameters were determined spectrofluorometrically and spectrophotometrically. Severe coronary atherosclerosis in group B was associated with higher serum low density lipoprotein/high density lipoprotein (LDL/HDL) cholesterol ratio, triacylglycerols, and phospholipids (P < 0.05). Erythrocyte membrane fatty acids C14:0, C16:1 and C22:6n3 were significantly higher in group B (P < 0.05). We found significantly higher plasma polyunsaturated fatty acids (PUFA) C18:3n6 in group B, whereas plasma linoleic acid was not changed significantly. There was a significant increase of IDL-C18:0, LDL-C14:0 and HDL-C22:6n3 PUFA in group B. We conclude that disturbances in saturated fatty acids (SUFA) and PUFA metabolism are associated with coronary atherogenesis. Such abnormalities may include enhanced extrahepatic transport of C14:0 SUFA via LDL and its incorporation into cell membranes, and enhanced clearance of anti atherosclerotic C22:6n3 PUFA via serum HDL.
