[Irritable bowel syndrome (IBS) is one of the most common gastrointestinal condition, which affects 10-15% of adults in developed countries. Recent observations have raised the possibility that disturbances in the gut microbiota and/or the accompanying low-grade inflammatory state might contribute to the etiology and symptomatology of irritable bowel syndrome. Some studies indicate that small intestinal bacterial overgrowth (SIBO), as confirmed by hydrogen breath tests (HBT), is more prevalent in patients with irritable bowel syndrome than in matched controls without IBS. Although the data are conflicting, this observation has led to the hypothesis that bacterial contamination was the primary cause of IBS. As a consequence of this hypothesis, a lot of therapeutic options have found their way into the armamentarium of those who treat patients with IBS. These agents include probiotics, prebiotics, antibiotics and anti-inflammatory agents. This paper describes the various mechanisms by which changes in the gut flora might contribute to IBS and also discusses the efficacy and safety of antibiotic therapies, especially rifaximin, for treating IBS/SIBO symptoms.]

[THE DIABETIC FOOT SYNDROME: PATHOMECHANISM, CLINICAL PICTURE, CURRENT TREATMENT AND PREVENTION]

JERMENDY György

[Diabetic foot syndrome is a characteristic late complication of diabetes mellitus. It can develop in patients with type 1 as well as type 2 diabetes mellitus, especially in case of a long duration of diabetes and sustained poor metabolic state. Diabetic neuropathy plays a pivotal role in the pathomechanism, but vascular symptoms might also contribute to the complex clinical picture. For making the diagnosis, evaluation of complaints, performing physical examination and using simple tests for identifying both distal, somatosensory neuropathy and potential angiopathy are of great importance. Therapeutic approaches aim to achieve proper glycaemic control, as well as to ameliorate symptoms of neuropathy, improve peripheral blood supply by medicines, angioplasty or intervention radiological methods, fight against infections and off-load the foot. Surgical intervention might also be necessary, and in severe cases, amputation might be needed. The diabetic foot syndrome increases mortality risk in patients with diabetes. Complaints related to diabetic foot syndrome are often resistant to treatment and tend to recur. Thus, prevention with long-term, good metabolic control and protection of the foot are of particular importance.]

[INSULIN SELF-TITRATION IN TYPE 2 DIABETES MELLITUS: BURDEN OR SOLUTION?]

TAKÁCS Róbert

[INTRODUCTION - Observational studies have verified that even in routine diabetes care, up to 1.3% reduction in HbA1c can be achieved with the initiation of a long-acting basal insulin analogue. We can get the same results in our patients using an insulin titration algorithm and close diabetological control. CASE REPORT - Metformin therapy of a 68-year old, moderately obese woman with type 2 diabetes was complemented by a long-acting basal insulin analogue (insulin glargine). Before initiation of insulin therapy, the patient received thorough dietetic and diabetic education by a qualified dietician and a diabetes nurse. The starting dose of insulin was 10 U, and then the patient was asked to increase the dose by 2 U every 3rd day depending on the mean of self-monitored fasting plasma glucose values in the previous 2 days. With the aid of a titration algorithm, optimal carbohydrate metabolism has been verified by laboratory parameters assessed 3 months later. CONCLUSION - Insulin self-titration based on appropriate patient education and close professional control makes a relatively simple therapeutic system the optimal decision in terms of a rapid and chronic normalisation of glucose control in a large patient group.]

[Role of β-blockers, especially carvedilol in the treatment of hypertension]

PÁLL Dénes, MARODA László, ZRÍNYI Miklós

[Changes in hypertension guidelines in the past years have affected the clinical thinking about β-blockers. Authors reviewed the development of β-blockers emphasizing the differences across various active pharmaceutical agents. Different hemodynamic and metabolic effects are being discussed in details for the third ge - neration vasodilatator carvedilol. Carvedilol has no effect on cardiac output but decreases peripheral vascular resistance which results in lower blood pressure values. However, carvedilol, opposite to unfavorable effects of traditional β-blockers, has a neutral impact on both carbohydrate and lipid metabolisms. Its more advanced cardiac effects include decreased left ventricular hypertrophy and increased coronary flow reserve. Vasodilatator type β-blockers (carvedilol, nebivolol) are indicated in the combi - nation treatment of hypertension, especially when the patient has heart failure, coronary disease or suffered from a previous heart attack.]

[Novelties in the management of Hodgkin lymphoma]

ILLÉS Árpád, MOLNÁR Zsuzsa, MILTÉNYI Zsófia

[Hodgkin lymphoma is a lymphoproliferativ disease, it is about 12-18% of all lymphomas. It has typical morphologic, clinical and therapeutic features, which can distinguish from other lymphoma types. Due to risk- and PET/CT adapted treatment Hodgkin lymphoma is a curable lymphoma with an 80-90% long-term survival, however, refracter- and relapsed patients’ therapy is a great challange. Cure rate can increase due to the development of the diagnostic and treatment modalities, but the use of standard recommendation is necessary. The aim of this review is to show new WHO 2016 lymphoma classifi cation, role of the new diagnostic options, especially 18FDG-PET/CT, Lugano classifi cation and fi rst-line and salvage therapeutic possibilities and to introduce the immunotherapy, like brentuximab vedotin and PD1 inhibitors. Certain points of hemopoietic stem cell transplantation will be also covered.]

[Diagnostic and therapeutical possibilities in constipation]

ILLÉS Anita, KIRÁLY Ágnes

[Constipation is a common gastrointestinal problem. The prevalence of symptoms related with constipation fluctuates from 3 to 20 per cent. Constipation occurs more frequently in the elderly people and in females and more frequent in case of inactivity and less fiber intake. Assesment of patients with severe constipation includes specialized investigations. Exclusion of primary organic causes has to be the first step, then metabolic, neurological and iatrogenic causes (such as medicament side effects, etc) have to be excluded. After these considerations special functional gastroenterological investigations are needed which contribute to the diagnosis and differential diagnosis of the cause of the constipation. Anorectal manometry, ballon expulsion test, defecography and colon transit studies allow us to distinguish between slow colon transit, colon inertia, different subtypes of outlet obstruction, and the constipation predominant irritable bowel syndrome. The evaluation of these specific studies leads to the exact diagnosis and appropriate treatement for their problem can be given to the patients, which always has to be individually planed in all cases.]

[VITAMIN D TREATMENT: HORMONE THERAPY FOR PATIENTS WHO NEED IT OR SIMPLY A SUPPLEMENTATION FOR EVERYONE?]

SPEER Gábor

[Various medical associations issue different recommendations for the prevention and treatment of vitamin D deficiency. These significant differences are partly explained by the different definition of normal vitamin D level and the use of completely different mathematical models to predict the increase in vitamin D level as a response to therapy. According to the Institute of Medicine (IOM), the target vitamin D level is 20 ng/ml, whereas the Endocrine Society (ES) recommends 30 ng/m as the miminum target value. According to the ES, a 1 ng/ml increase of vitamin D level can be reached by a daily intake of 100 NE, while the IOM recommends 3.6 ng/ml. Moreover, the IOM states that the effect of therapy on serum level is nonlinear. These differences show that the ES and IOM have different views on the risk of adverse effects. The IOM recommends 400 IU vitamin D daily for children younger than 1 year, 800 IU for those above 70 years and 600 IU/per day for everyone else. The ES recommend 400-1000 IU daily for all infants and 1500- 2000 IU for adults. Screening, however, is not recommended by either society. To decrease uncertainty concerning the side effects of higher-dose vitamin D treatment, it is important to understand, use and support the function of the pharmacovigilance system of the pharmaceutical industry that manufactures and markets various (prescription, over-the-counter) preparations. This is what the author aims to highlight in the second part of this article. Using this system, both the doctor and the patient can help support and accept the justification of higher-dose vitamin D therapy.]
