[Hyperbaric oxygen therapy in outpatient care]. / A túlnyomásos oxigénkezelés és helye az ambuláns ellátásban.

Hyperbaric oxygen therapy, or high pressure oxygen therapy, is a highly specialised branch of medicine. Applications and results date back to the 1960s and it has been used, researched and developed ever since. During the treatment, patients breathe 100% oxygen in a pressurised chamber. For clinical purposes, as defined, the pressure must equal or exceed 1.4 atmosphera absolute, most of the cases typically higher (2.0-2.5 atmosphera absolute). Oxygen dissolves by pressure in body fluids, transported by circulation to all tissues. Cellular regeneration and tissue processes are induced by both the increased oxygen supply and the intermittent change in tissue partial oxygen pressure associated with treatment. The effect can be used in the treatment of many diseases, usually as part of a complex treatment plan. Additional advantage is that it is a non-invasive and pain-free therapy. Evidence-based indications and general baseline usage are regulated by the European Underwater and Baromedical Society through the European Committee of Hyperbaric Medicine, in accordance with the principles of evidence-based medicine. The authors describe three cases in their publication where hyperbaric oxygen therapy significantly contributed to the success of overall treatment. Orv Hetil. 2023; 164(25): 993-996.

Incidence, Predictive Factors, Clinical Characteristics and Outcome of Non-variceal Upper Gastrointestinal Bleeding - A Prospective Population-based Study from Hungary.

BACKGROUND AND AIMS: Acute non-variceal upper gastrointestinal bleeding (UGIB) is associated with significant morbidity and mortality. Our aim was to evaluate the incidence, management, risk factors and outcomes of acute non-variceal UGIB in a population-based study from Hungary. METHODS: The present prospective one-year study involved six major community hospitals in Western Hungary covering a population of 1,263,365 persons between January 1 and December 31, 2016. Data collection included demographics, comorbidities endoscopic management, Glasgow-Blatchford score (GBS), Rockall score (RS) transfusion requirements, length of hospital stay and mortality. RESULTS: 688 cases of acute non-variceal UGIB were included with an incidence rate of 54.4 (95%CI: 50.5-58.6) per 100,000 per year. Endoscopy was performed within 12 hours in 71.8%. 5.3% of the patients required surgical treatment and the overall mortality was 13.5%. Weekend presentation was associated with increased transfusion requirements (p=0.047), surgery (p=0.016) and mortality (p=0.021). Presentation with hemodynamic instability or presence of comorbidities was associated with transfusion (p<0.001 both), second look endoscopy (p<0.001 both), re-bleeding (p<0.001 both), longer in-hospital stay (p<0.001 both) and mortality (p=0.017 and p<0.001). GBS was associated with transfusion requirement (AUC:0.82; cut-off: GBS >7points), while mortality was best predicted by the post-endoscopic RS (AUC:0.75; cut-off: RS >5points). CONCLUSIONS: Incidence rates of acute non-variceal UGIB in Western Hungary are in line with international trends. Longer pre-hospital time, comorbidities, hemodynamic instability, weekend presentation, treatment with anticoagulants or non-steroidal anti-inflammatory drugs was associated with worse outcomes.

Outcomes of variceal upper gastrointestinal bleeding: A prospective, multicenter, population-based study from West Hungary / A varixeredetu felso gastrointestinalis vérzések elemzése: yugat-magyarországi prospektív, multicentrikus, népességalapú vizsgálat

Összefoglaló. Bevezetés: Az akut varixeredetu gastrointestinalis vérzés napjainkban is jelentos morbiditással és mortalitással jár. Célkituzés: Célunk az akut varixeredetu felso gastrointestinalis vérzések incidenciájának, ellátási folyamatainak és kimeneteli tényezoinek átfogó felmérése volt. Módszer: Prospektív, multicentrikus vizsgálatunk keretében hat nyugat-magyarországi gasztroenterológiai centrum bevonásával elemeztük az ott diagnosztizált és kezelt, varixvérzo betegek adatait. Rögzítettük a demográfiai, az anamnesztikus, a diagnosztikus, valamint a terápiát és a betegség kimenetelét érinto adatokat. Minden beteg esetében kockázat- és predikcióbecslést végeztünk a Glasgow-Blatchford Score (GBS), a pre- és posztendoszkópos Rockall Score (RS) és az American Society of Anesthesiologists (ASA) Score alapján. Eredmények: A vizsgált egyéves periódusban (2016. 01. 01. és 2016. 12. 31. között) 108, akut varixeredetu gastrointestinalis vérzést találtunk (átlagéletkor: 59,6 év). Endoszkópos terápiára 57,4%-ban került sor, 39,8% sclerotherapiában, 18,5% ligatióban részesült. Transzfúziót a betegek 76,9%-a igényelt. A teljes halálozás 24,1% volt. A transzfúziós igény vonatkozásában a legmagasabb prediktív értéku a GBS volt (AUC: 0,793; cut-off: GBS >8 pont). Az ASA-pontszám szignifikáns összefüggést mutatott a transzfúzió-szükséglettel (OR 7,6 [CI 95% 2,7-21,6]; p<0,001), az endoszkópos intervencióval (OR 12,6 [CI 95% 3,4-46,5]; p = 0,033) és trendszeru kapcsolatot a mortalitással (OR 3,6 [0,8-16,7]; p = 0,095). Emellett a nemzetközi normalizált ráta (INR) értéke (p = 0,001) és a szérumkreatinin-szint (p = 0,002) állt kapcsolatban a mortalitással. Az endoszkópos intervenció aránya szignifikáns összefüggésben volt a varix Paquet-stádiumával (p<0,001) és az ASA-pontszámmal (OR = 12,6 [3,4-46,5]; p = 0,033). Következtetés: Nyugat-Magyarországon magas az akut varixeredetu vérzés elofordulási gyakorisága. Az ASA-pontszám és a GBS jó prediktív faktor a betegségkimenetel és a transzfúziós igény vonatkozásában. A megfigyelt magas mortalitás és az endoszkópos ligatio alacsony aránya indokolja a kezelési stratégiák optimalizálását akut varixeredetu gastrointestinalis vérzés esetén. Orv Hetil. 2021; 162(31): 1252-1259. INTRODUCTION: Acute variceal gastrointestinal bleeding is associated with significant morbidity and mortality. OBJECTIVE: Our aim was to evaluate the characteristics and prognostic factors in the management of acute upper gastrointestinal bleeding in a large multi-center study from Hungary. METHOD: This prospective one-year study (between January 1, 2016 and December 31, 2016) involved six community hospitals in Western Hungary. Data collection included demographic characteristics, vital signs at admission, comorbidities, medications, time to hospital admission and endoscopy, laboratory results, endoscopic management, risk assessment using Glasgow-Blatchford Score (GBS), Rockall Score (RS) and the American Society of Anesthesiologists (ASA) Physical Status Score, transfusion requirements, length of hospital stay and mortality. RESULTS: 108 cases (male: 69.4%) of acute variceal gastrointestinal bleeding were registered during the 1-year period. Endoscopic therapeutic intervention was performed in 57.4%. On initial endoscopy, 39.8% of the patients were treated with sclerotherapy and 18.5% had ligation. 76.9% of the patients required blood transfusion. The overall mortality (including in-hospital bleedings) was 24.1%. The GBS predicted transfusions (AUC: 0.793; cut-off: GBS >8 points). The ASA Score was associated with transfusion (OR 7.6 [CI 95% 2.7-21.6]; p<0.001), endoscopic intervention (OR 12.6 [CI 95% 3.4-46.5]; p = 0.033), and showed similar trend with mortality (OR 3.6 [0.8-16.7]; p = 0.095). The increased international normalized ratio (INR) and creatinine levels were associated with mortality (p = 0.001 and p = 0.002). CONCLUSION: Incidence rates of acute variceal gastrointestinal bleeding in Western Hungary are high. The ASA Score, GBS predicted outcomes and transfusion requirements. The observed high mortality rates, coupled with relatively low rates of endoscopic ligation, warrant optimization of management strategies in acute variceal gastrointestinal bleeding.

Frequency and characteristics of infusion reactions during biosimilar infliximab treatment in inflammatory bowel diseases: results from Central European nationwide cohort.

BACKGROUND: Safety data of the 'real life' use of an infliximab biosimilar, CT-P13 in inflammatory bowel disease (IBD) are still lacking. Our aim was to assess the frequency and characteristics of infusion reactions during CT-P13 therapy in 13 Hungarian and 1 Czech IBD centres. METHODS: Clinical and safety data was registered at fixed appointments. Trough levels and anti-drug antibody (ADA) concentration were measured by ELISA. Association between demographic, clinical, laboratory parameters and infusion reaction rates were evaluated statistically. RESULTS: Three hundred and eighty-four IBD patients were included. Twenty-eight Hungarian IBD patients (9.6%) developed infusion reaction during the treatment, 64.3% of them was previously exposed to anti TNF therapy. No infusion reaction occurred in the Czech population. CT-P13 therapy had to be stopped in 17 patients who developed infusion reaction and was switched to adalimumab in 12 patients. However in 39.3% of patients developing infusion reaction CT-P13 therapy was continued with the use of premedication. Cumulative ADA positivity rates were 8.7%, 19.3%, and 28.0% at weeks 0, 14, and 30. Previous anti-TNF-alpha exposure (30% vs. 3.1%, p < 0.001, OR 6.3 (2.7-14.6)) and ADA positivity (32.6% vs. 4.1%, p < 0.001, OR 19(5-73)) during the induction therapy were predictive factors for infusion reactions. CONCLUSIONS: Patients with previous exposure to anti-TNF-alpha and ADA positivity during the induction therapy were more likely to develop infusion reactions.

Prediction of Short- and Medium-term Efficacy of Biosimilar Infliximab Therapy. Do Trough Levels and Antidrug Antibody Levels or Clinical And Biochemical Markers Play the More Important Role?

BACKGROUND AND AIMS: Biosimilar infliximab CT-P13 received European Medicines Agency [EMA] approval in June 2013 for all indications of the originator product. In the present study, we aimed to evaluate the predictors of short- and medium-term clinical outcome in patients treated with the biosimilar infliximab at the participating inflammatory bowel disease [IBD] centres in Hungary. METHODS: Demographic data were collected and a harmonised monitoring strategy was applied. Clinical and biochemical activities were evaluated at Weeks 14, 30, and 54. Trough level [TL] and anti-drug antibody [ADA] concentrations were measured by enzyme-linked immunosorbent assay [ELISA] [LT-005, Theradiag, France] at baseline at 14, 30 and 54 weeks and in two centres at Weeks 2 and 6. RESULTS: A total of 291 consecutive IBD patients (184 Crohn's disease [CD] and 107 ulcerative colitis [UC]) were included. In UC, TLs at Week 2 predicted both clinical response and remission at Weeks 14 and 30 (clinical response/remission at Week 14: area under the curve [AUC] = 0.81, p < 0.001, cut-off: 11.5 µg/ml/AUC = 0.79, p < 0.001, cut-off: 15.3µg/ml; clinical response/remission at Week 30: AUC = 0.79, p = 0.002, cut-off: 11.5 µg/ml/AUC = 0.74, p = 0.006, cut-off: 14.5 µg/ml), whereas ADA positivity at Week 14 was inversely associated with clinical response at Week 30 [58.3% vs 84.8% ,p = 0.04]. Previous anti-tumour necrosis factor [TNF] exposure was inversely associated with short-term clinical remission [Week 2: 18.8% vs 47.8%, p = 0.03, at Week 6: 38.9% vs 69.7%, p = 0.013, at Week 14: 37.5% vs 2.5%, p = 0.06]. In CD, TLs at Week 2 predicted short-term [Week 14 response/remission, AUCTLweek2 = 0.715-0.721, p = 0.05/0.005] but not medium-term clinical efficacy. In addition, early ADA status by Week 14 [p = 0.04-0.05 for Weeks 14 and 30], early clinical response [p < 0.001 for Weeks 30/54] and normal C-reactive protein [CRP] at Week 14 [p = 0.005-0.0001] and previous anti-TNF exposure [p = 0.03-0.0001 for Weeks 14, 30, and 54] were associated with short-and medium-term clinical response and remission. CONCLUSIONS: In UC, early TLs were predictive for short- and medium-term clinical efficacy, whereas in CD, Week 2 TLs were associated only with short-term clinical outcomes.

[Rare side effects in management of hyperthyroidism. Case report]. / A hyperthyreosis kezelésének ritka mellékhatásai.

The authors present the case history of a patient suffering from hyperthyroidism. The diagnostic procedures revealed the presence of propylthiouracyl induced vasculitis with renal involvement, that recovered completely after the withdrawal of propylthiouracyl and corticosteroid treatment. Thereafter, the patient was treated with thiamasol, that caused agranulocytosis with fever. After transient litium carbonate therapy a succesful thyreoidectomy was performed. Cumulative serious side effects of antithyroid drugs are rare. This case highlights some of the challenges and complications encountered in the management of hyperthyroidism.

Efficacy and Safety of the Biosimilar Infliximab CT-P13 Treatment in Inflammatory Bowel Diseases: A Prospective, Multicentre, Nationwide Cohort.

BACKGROUND AND AIMS: Biosimilar infliximab CT-P13 is approved for all indications of the originator product in Europe. Prospective data on its efficacy, safety, and immunogenicity in inflammatory bowel diseases are lacking. METHODS: A prospective, nationwide, multicentre, observational cohort was designed to examine the efficacy, safety, and immunogenicity of CT-P13 infliximab biosimilar in the induction treatment of Crohn's disease [CD] and ulcerative colitis [UC]. Demographic data were collected and a harmonised monitoring strategy was applied. Early clinical remission, response, and early biochemical response were evaluated at Week 14, steroid-free clinical remission was evaluated at Week 30. Therapeutic drug level was monitored using a conventional enzyme-linked immunosorbent assay. RESULTS: In all, 210 consecutive inflammatory bowel disease [126 CD and 84 UC] patients were included in the present cohort. At Week 14, 81.4% of CD and 77.6% of UC patients showed clinical response and 53.6% of CD and 58.6% of UC patients were in clinical remission. Clinical remission rates at Week 14 were significantly higher in CD and UC patients who were infliximab naïve, compared with those with previous exposure to the originator compound [p < 0.05]. Until Week 30, adverse events were experienced in 17.1% of all patients. Infusion reactions and infectious adverse events occurred in 6.6% and 5.7% of all patients, respectively. CONCLUSIONS: This prospective multicentre cohort shows that CT-P13 is safe and effective in the induction of clinical remission and response in both CD and UC. Patients with previous infliximab exposure exhibited decreased response rates and were more likely to develop allergic reactions.

[The tip of the iceberg: multiple cutaneous sebaceous tumor in colon cancer. Muir-Torre syndrome--case report]. / A jéghegy csúcsa: multiplex faggyúmirigy-eredetu bortumor coloncarcinomában. Muir-Torre-szindróma.

Muir-Torre syndrome is a rare genodermatosis with autosomal dominant inheritance. The syndrome is considered to be a subtype of the hereditary nonpolyposis colorectal cancer (or Lynch-syndrome). In two-third of the cases, it develops as the consequence of germline mutations in mismatch-repair genes--most commonly MutS Homolog-2 and MutL Homolog-1. Its diagnosis can be established if at least one sebaceous tumor (sebaceoma, sebaceous adenoma, epithelioma, carcinoma or basal-cell carcinoma with sebaceous differentiation) and/or keratoacanthoma and at least one internal neoplasm are present. Here the authors present the history of a 52-year-old man with multiple sebaceous carcinomas on his back. Immunohistochemical analysis showed the lack of MutL Homolog-1 protein expression in the tumor cells. Detailed clinical workup in order to identify internal malignancy found malignant coecum tumor. Histopathological evaluation of the sample from the right hemicolectomy revealed mid-grade adenocarcinoma with MutL Homolog-1 and postmeiotic segregation increased-2 deficiency. The detection of the cutaneous sebaceous carcinoma and the application of the modern diagnostic methods resulted in identification of the associated colorectal cancer in an early stage; hence, definitive treatment was available for the patient.

[Statins and gastrointestinal cancers]. / Statinok és az emésztorendszeri daganatok.

The antitumour effect of statins has already been proven in animal experiments and human cancer cell lines in several gastrointestinal cancers. The chemopreventive mechanism is not completely clarified but the enhancement of oxidative stress, increased autophagy, altered expression of pro- and antiproliferative proteins and their influence on intracellular signaling pathways may play a role. Randomized studies, however, failed to confirme the expected results obtained from experimental studies. The goal of this review is to summarize the data available in the literature regarding the chemopreventive effects of statins on several gastrointestinal cancers. Results of clinical trials suggest that 10-20 mg statin daily has no or minimal antitumour effect. Chemopreventive effect of hydrophilic statins could not be detected but it seems to be significant in the case of hydrophobic statins. There are only few data available on the long-term daily use of 30-40 mg statins. Further long-term evaluation of the effect of statins regarding gastrointestinal cancers is needed, and an analysis of compound- and dose-related subgroups would be beneficial. Chemoprevention with statins cannot yet be accepted as standard medical practice. Use of statins as chemopreventive agents cannot be a substitute for regular oncological screening or surveillance.

[The role of endoscopic ultrasound in the diagnosis and therapy of gastrointestinal disorders]. / Az endoszkópos ultrahang alkalmazása a gastrointestinalis betegségek diagnosztikájában és terápiájában.

Endoscopic ultrasound is one of those diagnostic methods in gastrointestinal endoscopy which has developed rapidly in the last decade and has became exceedingly available to visualize the walls of the internal organs in details corresponding to histological layers, or analyze the adjacent structures. Fine needles and other endoscopic accessories can be introduced into the neighbouring tissues under the guidance of endoscopic ultrasound, and diagnostic and minimally invasive therapeutic interventions can be performed. The endoscopic ultrasound became more widely available in Hungary in recent years. This review focuses on the indications, benefits and complications of diagnostic and therapeutic endoscopic ultrasound. We recommend this article to gastroenterologists, surgeons, internists, pulmonologists, and to specialists in oncology and radiology. This recommendation was based on the consensus of the Board members of the Endoscopic Ultrasound Section of the Hungarian Gastroenterological Society.

[Types and management of perforations occurring during endoscopic retrograde cholangiopancreatography]. / Az endoszkópos retrográd cholangiopancreatographia során kialakult perforációk típusai és kezelésük.

The authors discuss the incidence of perforation related to endoscopic retrograde cholangio-pancreatography, which is relatively uncommon (0.3-1%) among other types of complications. Perforations can be classified into three types based on their forms and locations. Having reviewed the literature the authors conclude that the most common type is periampullary perforation and the less frequent one is peritoneal perforation. The former usually heals after conservative treatment, while the latter needs an operation. The authors emphasize the important prognostic role of timely diagnosis and surgical treatment if alarming signs (peritoneal, septic) are present. Known predisposing factors, when the procedure needs more careful attention, are also summarized (postoperative status, needle knife papillectomy, intramural contrast media, long lasting examination). After reviewing their own cases, the authors establish that the incidence of perforation in their own centre was four per thousand (10/2400), out of which nine were periampullar and one peritoneal type. In 6 cases operation was necessary, and there was no mortality. The authors conclude that individually tailored therapy can largely reduce the 30-40% mortality rate reported in earlier studies.

[A rare form of adrenal Cushing's syndrome]. / Ritka etiológiájú Cushing-szindróma.

The authors present the case history of a 74-year-old male suffering from aortic coarctation. His endocrine evaluation was initiated because of severe hypokalemia. The diagnostic procedures revealed the presence of Cushing's syndrome caused by bilateral macronodular adrenal hyperplasia. Because of the high risk of surgical treatment due to his cardiac condition, the patient was treated with the steroid biosynthesis inhibitor ketoconazole, which resulted in a clinical and biochemical regression of hypercortisolism. After interventional treatment of the aortic coarctation the physical and cardiac condition of the patient showed a significant improvement, indicating that despite an old age, surgery offered a valuable tool for management of the disease. To the best knowledge of the authors, the coexistence of aortic coarctation and bilateral macronodular adrenal hyperplasia has not been previously reported. Orv. Hetil., 154(50), 1999-2002.

[Role of pulse oximetric monitoring during gastrointestinal endoscopy. Prospective multicenter study of the Gastroenterology Working Group of the Veszprém Regional Committee of the Hungarian Academy of Sciences (VEAB)]. / Az endoszkópos vizsgálatok pulzoximetriás monitorozásának jelentosége. Az MTA VEAB Gasztroenterológiai Munkabizottságának prospektív multicentrikus vizsgálata.

INTRODUCTION: Recent guidelines recommend routine pulse oximetric monitoring during endoscopy, however, this has not been the common practice yet in the majority of the local endoscopic units. AIMS: To draw attention to the importance of the routine use of pulse oximetric recording during endoscopy. METHOD: A prospective multicenter study was performed with the participation of 11 gastrointestinal endoscopic units. Data of pulse oximetric monitoring of 1249 endoscopic investigations were evaluated, of which 1183 were carried out with and 66 without sedation. RESULTS: Oxygen saturation less than 90% was observed in 239 cases corresponding to 19.1% of all cases. It occurred most often during endoscopic retrograde cholangiopancreatography (31.2%) and proximal enteroscopy (20%). Procedure-related risk factors proved to be the long duration of the investigation, premedication with pethidine (31.3%), and combined sedoanalgesia with pethidine and midazolam (34.38%). The age over 60 years, obesity, consumption of hypnotics or sedatives, severe cardiopulmonary state, and risk factor scores III and IV of the American Society of Anestwere found as patient-related risk factors. CONCLUSION: To increase the safety of patients undergoing endoscopic investigation, pulse oximeter and oxygen supplementation should be the standard requirement in all of the endoscopic investigation rooms. Pulse oximetric monitoring is advised routinely during endoscopy with special regard to the risk factors of hypoxemia.

Similarities in serum acylcarnitine patterns in type 1 and type 2 diabetes mellitus and in metabolic syndrome.

BACKGROUND/AIMS: In type 1 diabetes (T1D), type 2 diabetes (T2D) and metabolic syndrome (MetS), the associated complex metabolomic changes in the involvement of carnitine metabolism in total carnitine ester level has already been documented; here we extended the investigations to the individual acylcarnitines. METHODS: The fasting serum acylcarnitine concentrations were determined in 49 T1D, 38 T2D and 38 MetS patients and 40 controls by isotope dilution electrospray ionization tandem mass spectrometry. RESULTS: The acylcarnitine profiles of the 3patient groups shared elements with the controls. Considerably higher levels of almost all short-chain acylcarnitines (p < 0.05) and lower levels of some long-chain acylcarnitines were detected in T2D and MetS patients. The amounts of C3 and C4 carnitine were higher and most of the medium-chain and long-chain acylcarnitine levels were lower (p < 0.05) in T1D and MetS patients than in the controls. In T1D and T2D, the levels of C3 and C4 acylcarnitines were markedly elevated and some long-chain acylcarnitines were lower than the controls (p < 0.05). Moreover, significantly lower concentrations of free- and total carnitine were observed in T1D patients (p < 0.05). CONCLUSIONS: Profound alterations were detected in acylcarnitine profiles in the 3 patient groups. Similarities in the patterns suggest different degrees of involvement of the same metabolic systems in a systems biology approach.

Antiphospholipid antibodies in relation to sterility/infertility.

Of the systemic autoimmune diseases that lead to sterility/infertility, antiphospholipid syndrome (APS) has an outstanding importance; it may be associated with abortion and premature birth which are included in its diagnostic criteria, as well as preeclampsia, pregnancy-induced hypertension, foetal retardation, miscarriage, stillbirth and sterility. Between 2004 and 2009, on the Department of Immunology in the Zala County Hospital, 100 female patients with sterility (st)/infertility (if) (33/67), (mean age: 34.08 years) underwent, in addition to history taking and physical examination, an assessment by immune-serologic tests (ANA, anti-dsDNA, ENA-Profile, anti-TPO, a-sperm, aCL, aPS, aß2GP1, aANX, and aPT). Positive aCL on two occasions could be demonstrated in 27/100 cases (27%) (st/if: 7/20). Among them 4 cases of primary APS have been diagnosed respectively. In the remaining 17 patients the clinical picture did not fulfil criteria. In addition to the twofold positive aCL, unusual antiphospholipid antibodies including aß2GP1, aPS or both were present in 1/27, 2/27 and 1/27 patients, as well as aANX and aPT in 3/26 and 1/27 patients respectively. One-time positive aCL occurred in 16/100 women (16%) (st/if: 5/11); among them aPT and aß2GP1 could be detected in 1/16 patient each. Based on the clinical picture, we raised the possibility of primary APS in 2/16 patients. Among the aCL-negative women, we found the unusual antibodies of APS in 8/57 patients (14%) including positivity of aß2GP1, aPS, aPT and aANX in 4/57, 4/57, 2/57 and 3/57 patients respectively; taking the clinical criteria of APS into consideration, primary APS could be stated in 2/57 patients of them. The 32 pregnancies developed in the follow-up period upon administration of acetylsalicylic acid (ASA) and maintenance dose low molecular weight heparin (LMWH), together with prednisolone in patients with secondary APS, resulted in 23 deliveries and 5 miscarriages; 4 pregnancies are currently in progress. The results of our investigations highlight the significance of demonstrating latent autoimmune diseases in female patients with sterility/infertility, as barrenness can be terminated by the appropriate treatment of these conditions.

[Predictors of efficacy, mucosal healing and dose intensification during the first year of adalimumab therapy in patients with luminal and fistulizing Crohn's disease. National data from Hungary]. / A klinikai hatékonyság, a nyálkahártya-gyógyulás és a dózisemelés prediktorai az adalimumabkezelés elso évében Crohn-betegségben szenvedo betegekben Magyarországon.

UNLABELLED: Adalimumab is a fully human monoclonal antibody targeting tumor necrosis factor with proven efficacy in the treatment of Crohn's disease in clinical trials. The aim of the present study was to investigate the predictors of medium term clinical efficacy and mucosal healing during adalimumab therapy in patients with Crohn's disease in specialized centers approved for biological therapy in Hungary. METHODS: Data of 201 Crohn's disease patients were prospectively captured (male/female: 112/89, median age: 24 years, duration: 8 years). Previous infliximab therapy was given in 97 (48.3%) patients, concomitant steroids in 41.3% and azathioprine in 69.2% (combined: 26.4%) of patients. RESULTS: Overall clinical response and remission rates at 24 and 52 weeks were 78% and 52%, and 69.4% and 44.4%, respectively. Endoscopic improvement and healing was achieved in 43.1% and 23.6%, respectively. In a logistic regression model, clinical efficacy and normalized C-reactive protein at week 12, need for combined immunosuppression at induction, shorter disease duration and smoking were identified as independent predictors for 12-month clinical outcome, while normalized C-reactive protein at week 12, clinical remission at week 24, frequency of previous relapses and smoking were associated to endoscopic improvement/healing. Dose intensification to weekly dosing was needed in 16.4%. Parallel azathioprine therapy and clinical remission at week 12 was inversely associated to dose escalation to weekly dosing. CONCLUSION: Clinical efficacy and normalized C-reactive protein at week 12, need for combined immunosuppression, luminal disease and smoking are predictors for medium term clinical efficacy/mucosal healing during adalimumab therapy, while parallel azathioprine therapy may decrease the probability for dose escalation.

Statintherapy in the primary and the secondary prevention of ischaemic cerebrovascular diseases.

INTRODUCTION: Stroke is a major public health problem. It is the third leading cause of death worldwide and results in hospital admissions, morbidity, and long-term disability. Despite the inconsistent or weak association between cholesterol and stroke, statins can reduce the incidence of stroke in high-risk populations and in patients with a stroke or transient ischaemic attack. METHODS: The aim of our study was to review the efficacy of statin therapy in both primary and secondary stroke prevention. We also reviewed the effectiveness and cost-effectiveness among different statins and we also reviewed the possible effect of treatment added to statin monotherapy. RESULTS: There is evidence that statin therapy in both primary and secondary prevention significantly reduces subsequent major coronary events but only marginally reduces the risk of stroke recurrence. There is no clear evidence of beneficial effect from statins in those with previous haemorrhagic stroke and it is unclear whether statins should be started immediately post stroke or later. There is a pressing need for direct evidence, from head-to-head trials, to determine whether individual statins provide differing protection from clinically important events in stroke prevention. It is possible that combinations of lipid-lowering agents did not improve clinical outcomes more than high-dose statin monotherapy, although clinical trials are still ongoing.

Clinical importance of aspirin and clopidogrel resistance.

Aspirin and clopidogrel are important components of medical therapy for patients with acute coronary syndromes, for those who received coronary artery stents and in the secondary prevention of ischaemic stroke. Despite their use, a significant number of patients experience recurrent adverse ischaemic events. Interindividual variability of platelet aggregation in response to these antiplatelet agents may be an explanation for some of these recurrent events, and small trials have linked "aspirin and/or clopidogrel resistance", as measured by platelet function tests, to adverse events. We systematically reviewed all available evidence on the prevalence of aspirin/clopidogrel resistance, their possible risk factors and their association with clinical outcomes. We also identified articles showing possible treatments. After analyzing the data on different laboratory methods, we found that aspirin/clopidogrel resistance seems to be associated with poor clinical outcomes and there is currently no standardized or widely accepted definition of clopidogrel resistance. Therefore, we conclude that specific treatment recommendations are not established for patients who exhibit high platelet reactivity during aspirin/clopidogrel therapy or who have poor platelet inhibition by clopidogrel.

The authors report a new method which was introduced last year in their unit. In a significant part of cholecystolithiasis, choledocholithiasis also exists. The diagnosis is sometimes fairly difficult, in these cases newly developed imaging methods (magnetic resonance cholangiopancreatography, endoscopic ultrasonography) can help. In cases of choledocholithiasis, when preoperative endoscopic retrograde cholangiopancreatography (ERCP) is unsuccessful, laparoscopic endoscopy can be performed. Authors describe this method as well as discuss the international literature, and review the cases of their own ten cases with this method. They emphasize the advantages of the new method in a certain subgroup of patients against the traditional sequential approach (preoperative ERCP than laparoscopic cholecystectomy) and also share their technical experiences. Finally, they underline the importance of the team work which supposes the cooperation of the gastroenterologist, surgeon and anesthesiologist in the indication, organization and implementation of the intervention.
