[Atrial fibrillation in athletes]. / Migotanie przedsionków u sportowców.

Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting up to 1-1.5% of the population. Regular physical activity reduces the risk of cardiovascular diseases, however several studies have shown paradoxically increased incidence of AF in people practicing sport, especially in elite athletes. The results of studies suggest a U-shape relationship between sport and risk of arrhythmia. Minor regular exertion protects from arrhythmia through reduction in AF risk factors, while intense physical activity increases the risk of arrhythmia. The etiopathogenesis of arrhythmia in athletes has not been fully elucidated yet, but it is definitely multifactorial. Arrhythmia's occurrence may be related to adaptative remodeling of a heart, autonomic nervous system alteration as well as may be associated with other factors like inflammation or dyselectrolitaemia. Atrial Fibrillation in athletes should always be considered as an abnormality which requires further investigation as in small percentage of cases arrhythmia may be the first manifestation of a structural heart disease or chanellopathy potentially leading to sudden cardiac death. Taking into account several problems related to pharmacotherapy, AF ablation has become the first line treatment in athletes.

The use of drotrecogin alfa (activated) in severe sepsis during acute pancreatitis - two case studies.

BACKGROUND: Twenty-five percent of patients with diagnosed acute pancreatitis (AP) present a severe form of it. One of the most widespread complications of such a form is severe sepsis or septic shock, in which mortality can reach 80%. A complication of this state is multiple organ failure, which requires multi-directional treatment in an intensive care unit (ICU). Among the standard therapies are: control of the source of infection, supportive treatment of failed organ function, and others (e.g. dietary therapy, pain management, and physiotherapy). It is also now possible to use recombinant human activated protein C [drotrecogin alfa (activated); Xigris, Eli Lilly, USA] in the treatment of severe sepsis. CASE REPORT: In this study, the cases of two patients in whom severe sepsis was found during the course of acute pancreatitis are presented. In both cases it was established clinically (by laparotomy) and bacteriologically that necrosis-altered fragments of the pancreas were the sources of infection. CONCLUSIONS: Both the cases presented indicate that drotrecogin alfa (activated) interrupts the developmental cascade of severe sepsis. Proofs of the efficacy of the treatment were improvements in the functions of organs previously insufficient during the course of sepsis. The rapid elimination of the drug allowed planning therapy strategies (the possibility of conducting surgical operations and smaller therapeutic interventions) without the risk of increased bleeding. The decision to use Xigris in severe sepsis during AP should always include consideration of the risk of bleeding in connection with the local status within the pancreas.
