[Diabetes mellitus and the liver cirrhosis]. / Diabetes mellitus a jaterní cirhóza.

Patients with liver cirrhosis have increased risk of diabetes mellitus development, especially when the underlying disease is hereditary hemochromatosis, autoimmune hepatitis, non-alcoholic steatohepatitis or chronic hepatitis C. Patients with associated diabetes according to liver cirrhosis complications have worse prognosis and the therapy is influenced by both diseases. The authors bring short review of particular diseases, diagnosis and treatment strategy.

[Survival of patients after TIPS in the University Hospital Hradec Kralove]. / Prezívání nemocných po TIPS ve Fakultní nemocnici Hradec Králové.

AIM: To analyze survival of patients after TIPS (transjugular intrahepatic portosystemic shunt). PATIENT SAMPLE AND METHODOLOGY: Between September 1992 and August 2010, TIPS was created in 848 patients of the University Hospital Hradec Kralove. These patients were divided into groups. Survival was analyzed using Kaplan-Meier survival curves. Differences between groups were evaluated using log-rank test. RESULTS: Ten percent of patients do not survive one month after TIPS, 40% of patients survive 5 years and 20% of patients survive 10 years. There were statistically significant differences between groups divided according to Child-Pugh classification (A vs B p = 0.0053; B vs. C p < 0.0001), indication for surgery [prevention of bleeding recurrence differed from refractory ascites (p = 0.0001) and the indication to stop acute bleeding (p = 0.026)]; aetiology of the liver disease [patients with alcoholic cirrhosis differed from patients with Budd-Chiari syndrome (p < 0.0001) and from patients with chronic viral hepatitis (p = 0.024)]. CONCLUSION: Survival of patients after TIPS is influenced by Child-Pugh score, indication and aetiology of the liver disease.

[Chronic gastrointestinal toxicity after external-beam radiation therapy for prostate cancer]. / Chronická gastrointestinální toxicita po zevní radioterapii karcinomu prostaty.

BACKGROUNDS: Chronic gastrointestinal (GI) toxicity is an important dose-limiting factor of prostate cancer treatment. Its incidence varies with the dose of radiotherapy and the external beam treatment technique; however, there are also other factors that should be considered. Despite all the efforts to diminish the incidence, chronic toxicity still remains an adverse event which can affect the quality of life in patients after prostate cancer radiotherapy. DESIGN: The aim of this review is to provide a detailed description of chronic GI toxicity after external beam radiation therapy for prostate cancer, its causes, development, symptoms and incidence in different treatment techniques, and to compare the development of GI toxicity from the beginning of curative prostate cancer radiotherapy to now. CONCLUSION: Thanks to up-to-date radiotherapy techniques, the incidence of chronic GI toxicity is relatively low despite high doses of about 80 Gy used in prostate cancer treatment. Further reduction of radiation complications could be achieved by using image-guided radiotherapy (IGRT), which enables more precise delivery of the radiation dose to the prostate, reduction of the margin around the clinical target volume (CTV) and the sparing of organs at risk.

[The impact of secondary insertion of ePTFE-coated stent on sustainable TIPS patency]. / Vliv sekundárniho zavedení ePTFE potahovaného stentu na udrzdení pruchodnosti TIPS.

OBJECTIVE: Retrospective evaluation of the effect of secondary insertion of ePTFE-coated stent in the treatment of TIPS dysfunction versus other current options (simple angioplasty, insertion of additional non-coated stent). PATIENT SET AND METHODOLOGY: From the beginning of 2000 to the end of 2004, there were 121 interventions for TIPS dysfunction performed in our centre in which a non-coated stent was used to make up the shunt at the time of intervention. Depending on the type of intervention, the patient set was divided in 4 groups: simple angioplasty (52 cases, 43%), insertion of non-coated stent (35 cases, 28.9%), insertion of non-dedicated ePTFE-coated stent (15 cases, 12.4%), and insertion of dedicated ePTFE-coated stent (19 cases, 15.7%). All patients were monitored on a regular basis after the intervention for shunt patency with the use of clinical examination and Doppler ultrasonography, or also portal venography. Primary shunt patency after the intervention was evaluated in all four groups by Kaplan-Meier analysis. The primary shunt patency results after the intervention were compared with the use Cox F text and logrank test. RESULTS: The intervention was successful in 120 cases (the overall technical success rate of all interventions was 99.2%). The primary shunt patency was 49.7 % after 12 months and 25.3 % after 24 months following sole angioplasty intervention; 74.9% after 12 and 64.9% after 24 months following intervention involving the insertion of non-coated stent; 75.2 % after 12 months and 64.5% after 24 months following intervention involving the insertion of non-dedicated ePTFE-coated stent, and 88.1% after 12 months and 80.8% after 24 months following intervention involving the insertion of a dedicated ePTFE-coated stent. A statistically significant improvement in shunt patency was obtained in the group of interventions involving the insertion of dedicated ePTFE-coated stent and in the group of interventions involving the insertion of non-coated stent as compared with the group of interventions involving sole angioplasty (p < 0.01). CONCLUSION: From among all the currently used methods of therapeutic intervention for TIPS dysfunction, the best, the best subsequent TIPS patency was obtained after intervention involving insertion of dedicated ePTFE-coated stent.

[MELD score in prediction of early mortality in patients suffering refractory ascites treated by TIPS]. / MELD skóre v predikci casné mortality u nemocných s refrakterním ascitem lécených pomocí TIPS.

UNLABELLED: Transjugular Intrahepatic Portosystemic Shunt (TIPS) is now well established in the treatment of complications of symptomatic portal hypertension such as acute or recurrent variceal bleeding, refractory ascites and Budd-Chiari syndrome. In some patients with refractory ascites who belong to group C according to Child-Pugh classification (score around 12), the indication of the procedure could be very questionable and early mortality is quite high. However, in some cases, the subgroup of such risky patients can profit from TIPS. Child-Pugh classification is used for the stratification of the patients routinely. During the last decade other scoring systems occured to bring a better prognostic value. MELD (Model for End stage Liver Disease) score, based only on laboratory values is one of them. Comparison of these two scoring systems in patients treated by TIPS in previous trials brought certain discrepancy, but MELD score seems to be better in predicting early mortality. The aim of our study was to determine retrospectively the predictive accuracy of MELD score for the early mortality in comparison to Child-Pugh score in patients treated for refractory ascites by TIPS. METHODS: We evaluated 110 patients (mean age 55 years) with liver cirrhosis (61% of patients with alcoholic etiology), who underwent TIPS for refractory ascites in our center from September 1992 to December 2003. MELD and Child-Pugh score was calculated and then compared between groups with early (one month), three month and one year mortality, and those who survived over this period (one, three and twelve months), comparing MELD and Child-Pugh score (ROC analysis and Student's T test were used). RESULTS: Mean follow up was 23 months. Average MELD score in the whole group was (16). In patients, who died within one month the score before TIPS was 21, three months 20 and 18 one year. Comparing MELD score between subgroups and then Child-Pugh score, only for MELD score there was a statistically significant difference (p < 0.05) in one month. Using ROC (AUC) analysis, discriminant power of MELD score was superior to Child-Pugh score for one (0.73 vs 0.63) and three month (0.73 vs 0.67) mortality. The discriminant power for one year mortality was low in both scores. CONCLUSION: MELD scoring system is a better tool to predict the risk of early mortality in patients with refractory ascites treated by TIPS than Child-Pugh classification. The discriminant power was low in both scores in one year horizon.

[Budd-Chiari syndrome and TIPS--twelve years' experience]. / Budduv-Chiariho syndrom a TIPS--12 let zkuseností.

BACKGROUND: Massive thrombosis of hepatic veins is clinically the most serious type of Budd-Chiari syndrome (BCS). Ischemic impairment is the basic problem in case of acute or fulminate course of BCS. Restitution of blood drainage within the liver is a key therapeutic approach in such situation. In chronic course of the disease, symptoms of portal hypertension as ascites, G1 bleeding or hepatorenal syndrome are more common. The portosystemic shunt leads both to blood outflow restitution and to the decrease of portal hypertension. TIPS is a promising method due to minimal perioperative risk for the patient in critical situation and also due to its easiness of use. The aim of our study was to determine the clinical outcome in patients with BCS treated by TIPS in a retrospective analysis. METHODS AND RESULTS: During 12 years 23 patients with intraparenchymal thrombotic occlusion of hepatic veins were treated using TIPS, 17% were children, only 4 patients (17%) were men, the median age was 33.3 years (range 13 to 75 years). One third of the procedures was performed as urgent. In 2/3 of patients thrombosis developed in relation to myeloproliferative syndrome, in nearly 1/3 the origin of thrombosis was not detected. In 2 patients a defect of coagulation was revealed. In the first 11 patients the bare stent was used, the consecutive 12 patients received the ePTFE covered stent (stentgraft). Six patients died during follow-up: I due to fulminate liver failure, 2 due to liver failure caused by acute shunt occlusion, 1 due to the progression of the underlying hematooncological disease; the reason of death in 2 patients was not known. One patient was treated by OLTx during follow-up. The 17 surviving patients are in good condition with good shunt function although they need anticoagulant therapy and intermittent reinterventions. The average period between revisions was 2-3 years, 2 patients had no revision of TIPS for 4 years. The use of ePTFE covered stents had no effect on the number of early occlusions (approx. 18%), the occurrence of late stenoses and occlusions was substantially decreased (p=0.04, log-rank test). CONCLUSIONS: Standing on this experience we consider TIPS, in accordance with literature data, an advantageous therapeutic approach in Budd-Chiari syndrome caused by massive liver vein thrombosis. If the follow up treatment is rigorous, the TIPS usually ensures the necessary perfusion and the function of the liver So it may spare the patients of objectionable liver transplantation.
