Erosive and ulcerative

The first kidney transplant HIV-infected Muller and her colleagues met for about two years ago. Total to date South African Transplant spent nine similar operations.

Fear of doctors who conducted the transplant, is the possibility brand viagra online of a recipient of reinfection (superinfection), as if infected by different strains of immunodeficiency virus may appear resistant to antiretroviral agent.

In this regard, the kidneys were taken from HIV-infected donors who had died not from AIDS but for other reasons, including as a result of an accident. Physicians selected donors who did not receive antiretroviursnye drugs, and do not suffer from typical of AIDS opportunistic infections.

Renal function after transplantation recovered from all recipients. Mueller noted that all transplant patients feel fine. Transplant added that a report on the transactions she was invited to speak at a conference of the National Institutes of Health
One of the most serious complications in victims of severe thermal burns - bleeding from the upper gastrointestinal tract (GIT), occurs with a frequency 0,15-41,5% [5, 6, 14, 15, 23]. If the fatality rate of bleeding from upper GIT in victims of severe injuries ranging from 8 to 30%, then baked, it can reach 80%. The main source of bleeding in these patients are acute erosion and ulcers of the esophagus, stomach and duodenal ulcer (DU) [7, 24, 30, 32, 34, 39].

Acute erosion and ulcers occur in all parts of the intestinal tube [15]. Most often they manifest complications as bleeding or perforation [19, 24, 27, 28]. Patients being treated in intensive care units, the frequency of clinically significant gastrointestinal bleeding (hypotension, transfusion needs in the blood) is 1.5% [43, 46].

In modern classifications among ulcer bleeding on etiologic grounds allocated hemorrhage from acute ulcers on the basis of stress [16, 17]. According to IS Osipov [15], acute gastrointestinal generic viagra ulcers differ from stress the fact that the formation of the first major role played by the weakening of protective factors and trophic disorders in the walls of hollow organs of the digestive tract, the latter developed mainly as a result of the activation factors of aggression. Such a division in the clinic looks rather arbitrary, since tyazheloobozhzhennyh these processes occur together, are closely related to each other, and treatment should be directed to all the possible pathogenesis. In foreign literature, and acute stress ulcers is not clearly separated. The term "stress ulcer" is usually applied to mucosal lesions, diagnosed in patients who are critically ill or exposed to stress of any origin [31, 41, 43, 44]. Severe surface erosion are usually multiple, starting in the fundus of the stomach, and progress towards the antral region and duodenal [23, 28, 29, 36, 44, 46].

It is noted that victims of severe thermal burns frequency and amplitude of erosive and ulcerative lesions of upper gastrointestinal bleeding and are directly proportional to the area and depth of burn and degree of burn shock [7]. Acute erosion and ulcers in the gastrointestinal tract in patients younger than 60 years often develop with burns over 20% of the body, the older - and with minimal burns (10%), and with increasing area of the burn increases the risk of erosive ulcer bleeding at all stages of burn disease. At the risk of bleeding should also include patients with isolated burns of the respiratory tract II-III degree burns or with a combination of airway and limited skin burns [6, 34].

Various theories of the pathogenesis of erosive and ulcerative lesions of upper gastrointestinal mucosa, but none of them can not fully explain the occurrence of acute ulcers. It is recognized that the final link ulcerogenesis is disruption of the normal balance of protective brand name levitra factors and aggression in relation to the mucosa [13, 45].

The factors protect the gastric mucosa and duodenum are: 1) mucous-bicarbonate barrier, 2) a system of endogenous prostaglandins, and 3) mechanisms for active regeneration of epithelium, and 4) an intense circulation in the mucosa, 5) antroduodenalny "acid brake". Aggression factors include: 1) acid-peptic factor, and 2) contamination of the gastric mucosa Helicobacter pylori; 3) gastroduodenal dismotoriku and 4) mucous traumatism, and 5) increased cialis without prescription activity of free radical oxidation of lipids [18, 21, 28, 38].

A large body of evidence suggests that upper gastrointestinal hypoperfusion can lead to ulceration of the mucosa [44, 45]. In tyazheloobozhzhennyh Education acute erosions and ulcers in the esophagus, stomach, duodenum is one component of multiple organ dysfunction syndrome (MODS), often leading to death [6, 27, 37, 49]. This syndrome leads to an increase in the frequency of adverse outcome of disease in surgical clinics and the leading cause of mortality in patients in critical condition [9, 11]. The basis of the formation of OPA is a systemic inflammatory response syndrome - a non-specific response against any deleterious effects [9]. AS Ermolov et al. [7] have revealed at roasted high levels of endogenous intoxication, which is recognized as a major factor of lesions causing erosive ulcer bleeding.
