[Exocrine and endocrine pancreas constitutes close anatomical and functional links accordingly, any disease affecting one of these sectors will inevitably affect the other. Acute and chronic pancreatitis, pancreatic surgery, cystic fibrosis and pancreatic cancer are those pancreatic conditions that might cause diabetes mellitus. The development of diabetes greatly influences the prognosis and quality of life of patients with exocrine pancreatic diseases. The lack of glucagon and the impaired absorption of nutrients may cause life-threatening complications, such as hypoglycaemia, and the micro- and macrovascular complications may impair the organ functions. Diabetes mellitus is an independent risk factor of mortality in those with exocrine pancreatic diseases. Pancreatic diabetes is a distinct metabolic and clinical form of diabetes, requires special treatment. Diet and pancreatic enzyme replacement therapy may be sufficient in the early stages. Oral antidiabetic drugs are not recommended. If the diet proves inadequate to reach the glycaemic goals, regular insulin treatment is demanded. There are special impairments of the exocrine function and the pancreatic morphology at diabetic patients that resemble to chronic pancreatitis. Atrophy of the exocrine tissue may caused by the lack of trophic insulin. Hyperglycaemia can activate the stellate cells that lead to pancreatic fibrosis. The microangiopathy and neuropathy, as well as the lack of islet hormone action - responsible for the exocrine pancreas regulation - will cause further damage on the pancreas glandular tissue. In the event of a proven impairment of the pancreatic exocrine function in diabetes mellitus, pancreatic enzyme replacement therapy is recommended. This may improve the nutritional condition and decrease the metabolic instability.]

[Dietary treatment of dialysis patients]

ZAKAR Gábor

[Adequate nutritional indices and intake are the corner stone of long term success of renal replecement therapies (hemo- and peritoneal dialysis, transplantation) characterized by favourable survial rates and a good quality of life. There has been no major change in basic principles of nutritional prescription (protein, energy, fluid intake, restriction of sodium, potassium and phosphorous), increasing emphasis has been placed on the reduction of calcium load and ”native” vitamin-D therapy in these patients. Less avareness has been put however in the past ten years (according to recent metaanalyses) on the role and replacement of the full scale of vitamins, in spite of their occasionally altered metabolism and replacement-requirements in ESRD patients. Usually there is a need for their replacement, but some of them are represented in abundant, sometimes toxic amounts in commercially available multivitamin preparates. With in the scope of general aspects of nutrition in ESRD patients, the article gives a detalied overview of their multivitamin recommendations and alternatives of a specified substition.]

[Modern medical and dietary treatment of gout in light of the new American guidelines]

SZEKANECZ Zoltán

[After several decades of “silence”, in the past few years a number of new data and treatment options have become available regarding the management of hyperuricaemy and gout. We also have a better understanding of the immunpathogenic processes of the disease, resulting in new medicines, as well as dietary and lifestyle modifications. Finally, in 2012, the American College of Rheumatology (ACR) has published new guidelines, which provide detailed algorhythms for each stage of gout and for special clinical situations. Although some aspects of clinical practice in Europe are different from that in the US, the new guidelines are applicable - with the necessary adaptations - in Hungary for the efficient treatment of gout and its comorbidities.]

[AUTOIMMUNE PANCREATITIS - AN UNDERDIAGNOSED DISEASE?]

CZAKÓ László

[Autoimmune pancreatitis is a recently recognized type of chronic pancreatitis that is clearly distinct from alcoholic chronic pancreatitis. Its clinical symptoms include jaundice, abdominal pain, weight loss and diabetes mellitus. It may be associated with other autoimmune diseases. IgG levels are elevated and autoantibodies can be detected. Pancreatic imaging reveals a diffuse enlargement of the pancreas and irregular narrowing of the main pancreatic duct. The characteristic histological features are lymphoplasmacytic infiltration and fibrosis. Autoimmune pancreatitis responds dramatically to steroid therapy, in contrast to other types of chronic pancreatitis, which hardly respond to any of the various therapies. It is important to be aware of this disease because it may be mistaken for other forms of chronic pancreatitis or pancreatic cancer, which leads to pancreatic resection when steroid treatment would be sufficient. This review discusses the clinical, laboratory, histological and imaging findings that are seen in autoimmune pancreatitis with particular focus on diagnosis. With the improvement of the diagnostic work-up less unnecessary pancreatic resections are expected to happen in patients with autoimmune pancreatitis.]

[New opportunities for the estimation of health loss in Hungary]

VITRAI József, VARSÁNYI Péter, BAKACS Márta

[BACKGROUND - The Global Burden of Disease Study has been publishing its reports since the early 1990’s. The last one from 2010 covers 291 diseases, and 67 risk factors for 187 countries. AIMS - Presenting examples of the Hungarian health burden status the authors advocate the use this unique data source. METHODS - The authors downloaded the 1990 and 2010 data for Hungary from the Global Burden of Disease Study website. To quantify the economic burden they calculated the change in GDP related to the absence from work as a consequence of risks and diseases. RESULTS - In the publication the authors presented some of the versatile utilization methods of the GBD data and the data visualization tools available on GDB’s website. In 2010 the DALY for Hungary was 3,714,900 years which is the 84% of the country’s DALY in 1990. The most Years Lived by Disability was caused by musculoskeletal disorders (YLD: 28.4%), while cardiovascular and circulatory diseases caused the most Years of Life Lost (YLL: 40.3%). In 2010 the dietary risk was the leading risk factors in Hungary accountable for 840 thousand of life years lost which economic cost was over 950 milliard Hungarian forints. CONCLUSIONS - The use of the result provided by the Global Burden of Disease Study can significantly contribute for planning and evaluating interventions to promote healthy lifestyle, to advance supporting living conditions, and to distribute health care capacity efficiently.]
