[Sudden death of a patient with purpura - post mortem recognized eosinophilic granulomatosis with polyangiitis]

DOBREAN Noémi, HAJNAL-PAPP Rozália, TUSA Magdolna, OROJÁN Iván, CSERNI Gábor

[INTRODUCTION - Systemic diseases may sometimes be challenging because physicians do not think about synthesizing the parts to a single entity. CASE REPORT - A 49-year-old asthmatic female was admitted to hospital for the investigation of her cutaneous symptoms suggestive of vasculitis associated with diffuse joint complaints. The chest X-ray raised the possibility of pneumonia or neoplastic disease. Following an episode of chest pain relieved by a non-steroidal anti-inflammatory drug, she suddenly died. Her previous history included restrictive cardiomyopathy, insufficiency of both atrioventricular valves and long dating eosinophilia. Autopsy revealed a partly granulomatous eosinophilic inflammatory process in several organs, including the heart, the lungs, the kidneys, the colon and the pituitary gland. Retrospective collection of unknown anamnestic features and symptoms made possible to unify the pieces of information and symptoms to a single entity, the Churg-Strauss syndrome (eosinophilic granulomatosis with polyangiitis, EGPA). CONCLUSIONS - Bronchial asthma seldom leads to death. It can rarely be part of the Churg-Strauss syndrome, of which the manifestation may be related to the administration of leukotriene antagonists also used in the presented case. These drugs may allow the withdrawal of systemic steroid therapy which is beneficial not only in the treatment of asthma but also of the syndrome. Lowering the dose of steroids may promote the development of the full blown pattern of the latter.]

[Perioperative management of patients taking new oral anticoagulants - dabigatran in focus]

MÁRK László

[Appearance of new oral anticoagulants (NOAC) on the market requires a basically new approach from the doctors compared to vitamin K antagonists (VKA), the only oral anticoagulants used for several decades. These new drugs are at least as effective in the prevention of thrombotic events as the old ones and have the advantage that no regular laboratory monitoring is needed. Compared to the VKA a different management is required also in the perioperative care of patients taking NOAC. There is no need for bridge therapy, i.e. low-molecular-weight heparin (LMWH). The smaller surgical procedures can be performed 24 hours after the last dose of NOAC if it is administered once a day or 12 hours in case of agents administered twice a day. When a large surgical procedure is planned the drug should be stopped 24-96 hours before. The therapy should be resumed 6-8 hours after the procedure in low, 48-72 hours later in high bleeding risk cases. In a Canadian prospective study a protocol was used in which the stopping and resumption of dabigatran was recommended based on the bleeding risk and its half-life depending on the renal function. In 541 surgeries (60% with standard, 40% with increased bleeding risk) the occurrence of serious bleeding events was 1.8%, that of minor bleedings 5.2%. During the study one thrombotic event (TIA) occurred (0.2%). At the end of the article the author also makes a recommendation for stopping and resuming dabigatran therapy in case of tooth extraction, endoscopic biopsy and cholecystectomy.]

[Day-to-day blood pressure variability measured with home monitoring for the verification of succesful antihypertensive therapy]

KÉKES Ede, PAKSY András, KISS István

[The value of „day-to-day” blood pressure variability based on home blood pressure measurements for demonstrating of successful antihypertensive treatment. Authors analyzed the effect of antihypertensive therapy on the blood pressure variability by day-to-day method based on home pressure measurements in a large number of hypertensive patients. During the four months observation period the mean blood pressure values were significantly decreased and the parameters of blood pressure variability were decreased as well, they reached the level of normal variability. The nowadays expected „double target values” has given us hope that we can successfully prevent the organ damages due to high blood pressure. The effects of some „drug family” and the drug-combinations to the blood pressure variability were analyzed. The RAS inhibitors (ACEI and ARB) reduced significantly the blood pressure variability, the ARB drugs more effectively. The ACEI agents combined with calcium antagonists or third-generation beta-blockers increased the normalization of blood pressure variability. Such effects were not observed with the ARB agents. Authors suggested the use of their method in every day practice. The guidelines also recommend this method.]

[The importance of the increase in the use of fix dosage combination of calcium channel blockers in the domestic medical practice between 2007 and 2013]

BARNA István, GYURCSÁNYI András

[Antihipertensive therapy in the complex treatment of diabetes mellitus, obesity and lipid metabolism disorder was discussed, which also means the fight against the emergence of cardiometabolic syndrome and chronic renal failure as well. Angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor antagonists (ARBs), calcium channel blockers (CCB), b-blockers and thiazid diuretics with “A” level of evidence reduce cardiovascular morbidity and mortality. The main effect of CCBs is effective antihipertensive vasodilatation, which is the basis of anti-ischaemic, anti-anginal and antihipertensive agents for use in everyday practice. Based on the database of the National Health Insurance, we analyzed changes in the turnover of CCBs between 2007 and 2013 the examined period among CCBs ordered with TB support amlodipin is the most frequently used active ingredient. In December 2007 almost 75% of the prescriptions was amlodipin. That increased to 87,12% by December 2013. CCBs ordered in monotherapy not changed in the examined period, while combinations increased continuously Among CCBs between 2007 and 2013 the fix dosage combinations available with TB support are: statins (atorvastatin + amlodipin), ACE inhibitors (ramipril + felodipin, lisinopril + amlodipin, perindopril + amlodipin, ramipril + amlodipin, verapamil + trandolapril) and b-blockers (metoprolol + felodipin). Using the assigned CCB monotherapy decreased steadily during the study period, while the use of combination formulations induced gradually increased. At the end of the examined seven year period more than 40% of the prescribed boxes were CCB in fix combination. Use of the combination of amlodipin + perindopril increased while amlodipin + lisinopril continuously reduced. The use of the combination of felodipin + ramipril also decreased.]

[Efficacy of anticoagulation with vitamin K antagonists in acut stroke patients with atrial fibrillation - Hungarian results]

SAS Attila, CSONTOS Krisztina, LOVÁSZ Rita, VALIKOVICS Attila

[Background and objective - An estimated 20% of ischemic strokes are of cardiogenic origin, half of which is associated with atrial fibrillation (AF). Anticoagulation treatment of patients with this arrhythmia reduces their risk of stroke. Effectiveness and safety of oral anticoagulant therapy with vitamin K antagonists (VKA) is limited, however, by their well-known narrow therapeutic window and the substantial inter- and intraindividual variability of INR values depending on genetic and dietary factors as well as drug interactions. Our objective was to evaluate the prevalence of adequate anticoagulation and the level of anticoagulant effect actually achieved among patients with AF hospitalized for acute stroke. Methods - Patients with AF admitted to our hospital ward in 2012 for acute stroke (n=226) were included in the analysis. Using descriptive statistics, relevant clinical and therapeutic characteristics of the patients were assessed, with special reference to the INR values on admission (among patients with known AF), and the clinical outcomes. Results - Of the study cohort, 170 patients had a diagnosis of AF before the admission for stroke, but 47% of them did not take anticoagulants. Patients who suffered stroke while on anticoagulants (83 on VKA, 7 on low-molecular-weight heparins), were in most cases (75%) out of the therapeutic INR range, typically undertreated (INR<2). Overall, inadequate or completely absent anticoagulation was documented in 81% of the stroke cases occurring in patients with known AF. Of the entire study cohort, 41% was discharged home, 34% required continued institutional care, and 25% died. Conclusions - The inadequacy or lack of anticoagulation was observed in the vast majority of acute strokes in patients with known AF. These cases are often related to the well-documented limitations of VKA therapy in terms of its safety, tolerability and/or practical aspects. To prevent them, important changes are warranted in the anticoagulation practice, including the closer control of VKA therapy and the broader use of new oral anticoagulants.]

[A novel rapid IL-6 release assay using blood mononuclear cells of patients with various forms of drug induced skin injuries]

BALÓ-BANGA J. Mátyás, SCHWEITZER Katalin

[INTRODUCTION - IL-6 is a multifunctional cytokine with effects on the haematopoiesis on differentiation of T and B lymphocytes and on the regulation of both inflammatory and allergic reactions. The question arose whether this substance excreted by mononuclear cells could be used as a marker of allergy to drugs or not. Till now equivocal descriptions were lacking. METHOD - The preformed IL-6 present in the mononuclear cells released by any of four standard dilutions of pure substances upon 20 minutes incubation was determined from the supernatants by ELISA technique. In vivo patch, intradermal and provocation tests were carried out along with this assay (483 in vitro and 172 in vivo). RESULTS - Two different groups suspect for drug allergy (100 and 62 patients as well as their matching controls, 24 and 23 persons) were involved with these procedures. In some cases TNF-α, IL-2, IFN-γ and IL-4 was measured simultaneously by flow cytometric assay. Only TNF-α and IL-6 were present in the 20 min. supernatants. The comparisons with in vivo tests have confirmed that the amount of IL-6 release had not depended either on the clinical phenotype of allergy or on the structure of the tested drugs within the molecular mass range between 76-4000 Da. IL-6 released at the lowest or multiple concentrations of drugs coincided with more severe and widespread clinical forms. CONCLUSION - Based on the results we elaborated an in vitro method applicable clinically for detecting drug sensitisation and its differential diagnosis in patients with skin signs of drug sensitisation.]

[The role of diet in the prevention of musculoskeletal diseases]

SPEER Gábor, SPEER Józsefné

[In the European Union, the lowest incidence of osteoporosis and rheumatoid arthritis has been reported in the Mediterranean area. However, for a long time only a few nutrients’ effects have been studied on BMD. Of these, the favourable effects of wine, fermented cheese and fruit and vegetable consumption have been demonstrated in the alleviation of both osteoporosis and rheumatoid arthritis. A number of promising studies are being conducted with analogues of antioxidant components of the mediterranean diet. Some of these components decrease the levels of pathological factors, such as interleukin-1, -6, -17, TNF-α, JAK2/STAT3, which are the targets of a number of efficient drugs. These findings demonstrate the significance of diet in the development of musculoskeletal diseases. In our review article, we present the above mentioned data, illustrated by some of our own recipes.]

[Effective, safe stroke prevention with novel oral anticoagulants in patients with atrial fibrillation. Focus on dabigatran]

SZAPÁRY László, FEHÉR Gergely, BOSNYÁK Edit, DELI Gabriella, CSÉCSEI Péter

[Non-valvular AF is the most common cardiac arrhytmia. Its incidence increases with age. AF is an independent risk factor for ischaemic stroke, representing a five times higher risk for it, associated with a high mortality rate. Beside AF, there are several other risk factors which influence the risk of stroke. Stroke risk calculator can be used to assess the risk of patient having a stroke. The most endangered group of patients with AF are those who have already suffered from cerebrovascular event. The only effective medication for prevention of stroke due to AF had been the application of vitamin K antagonists (VKA) which considerably decrease the rate of ischaemic event in a patient with AF providing that the INR is in the therapeutic range. VKA have several limitations of use in clinical practice and the fear of bleeding complications results an underusing of these drugs. Only 50% of all patients treated with VKA reaches the therapeutic range of INR. The breakthrough of prevention of stroke in recent years is undisputedly the coming out of novel oral anticoagulants (NOACs, thrombin and Xa-factor inhibitors). Recent studies suggest that these novel drugs prove the same efficacy as VKA drugs, furthermore dabigatran in a dose of 2×150 mg or apixaban in 2×5mg was statistically superior to warfarin in the prevention of stroke. NOACs have shown a large reduction in intracranial hemorrhage compared with warfarin. They are given as a fixed dose and do not require persistent monitoring making them much more convenient. NOACs at guidelines of European Society of Cardiology act as a preferable drugs in case of ischaemic stroke with AF. Probably the extended use of NOACs in clinical practice will be the mainstream of stroke prevention in the future.]

[Apixaban: the newest oral anticoagulant in Hungary for the treatment of patients with atrial fibrillation]

BORBÉLY Attila, ÉDES István

[In the past few years a number of articles have been published on the new oral anticoagulants (Xa-factor inhibitors, thrombin inhibitors). These new agents are increasingly used in the daily clinical practice in Hungary. The new oral anticoagulants have been shown to be at least as effective in the prevention of stroke and systemic embolization related to non-valvular atrial fibrillation as K vitamin antagonists. Moreover, their use is safe, can be administered in a daily fixed dose and, even in case of long-term use, they do not require regular laboratory testing. This review aims to summarise the most important theoretical and practical information on the newest direct Xa-factor inhibitor agent apixaban from the perspective of a cardiologist.]

[Acute heart failure and acute renal injury: pathophysiology and management of cardiorenal syndrome type 1]

LÁSZLÓ Ágnes, ÁCS Tamás, JÁRAI Zoltán

[The functional connection between heart and kidney is well known. Several types of this relationship have been recently characterized as cardiorenal syndromes. The relevance of this relationship in clinical practice is supported by the fact, that the consequences of the primary dysfunction are profoundly influenced by the magnitude and the treatment possibilities of the secondary dysfunction. Moreover, the administered therapy for heart failure can deteriorate renal hemodinamics, or side effects of the treatment can lead to the worsening of the clinical picture. Loop diuretics decrease venous congestion, but also induce neurohormonal activation and a decrease in glomerular filtration rate. The body of positive evidence with the use of mineralocorticoid receptor antagonists in acute settings is limited. Inotropic agents on the one hand improve hemodinamics, on the other hand increase the danger of arrhythmia and mortality (levosimendan seems to be an exception). Aquaretics decrease symptoms without influencing mortality. The natriuretic peptide neseritid improved clinical symptoms, but did not improve endpoints in clinical trials. Vasodilators improve hemodinamics, but their usefulness is limited because of their profound hypotensive effect. The effectiveness and benefits of ultrafiltration has to be tested in more clinical trials. Because of such treatment difficulties the management of these patients is a complex task that needs the involvement of intensive therapeutic specialists, nephrologists and cardiologists. This review focuses on the pathophysiology and possible management of the patients with acute heart failure with acute kidney injury, called type 1 cardiorenal syndrome from the cardiologist’s point of view.]
