Early jejunal nutrition and changes in the immunological parameters of patients with acute pancreatitis.

BACKGROUND/AIMS: We have compared the effects of glutamine-rich Stresson Multi Fibre and of Nutrison Fibre nutrients on the changes of some immunological parameters of 16 patients with acute pancreatitis. Laboratory parameters included: total protein, albumin, prealbumin, retinol binding protein, IgG, IgA, IgM, IgE, complement components: C3, C4, acute phase proteins: C-reactive protein, transferrin, CD-markers of peripheral lymphocytes and activity of peripheral phagocytes. METHODOLOGY: Nine patients were supplied with Stresson Multi Fibre and 7 patients with Nutrison Fibre, using a nasojejunal tube. The levels of serum proteins were measured with laser nephelometry, the CD markers of lymphocytes with flow cytometry and the phagocytic activity with chemiluminescence. RESULTS: The treatment with glutamine-rich Stresson resulted in significant elevations in the serum levels of IgG, retinol binding protein, compared to the effects of Nutrison Fibre. In addition, the recovery of treated patients was significantly shorter in the Stresson Multi Fibre group than in the Nutrison Fibre group. CONCLUSIONS: The Stresson Multi Fibre nutrient treatment of patients treated for acute pancreatitis seems to have clinical benefit based upon the fast recovery of IgG, IgM proteins which take part in the immunological defense mechanisms.

Changes in the nutritional state and immune-serological parameters of esophagectomized patients fed jejunaly with glutamine-poor and glutamine-rich nutriments.

BACKGROUNDS/AIMS: In our former study we investigated the effect of glutamine-rich (I) and glutamine-poor (II) jejunal diet in operated patients with acute pancreatitis. In the glutamine-rich diet group clinical benefit and fast recovery of IgG, IgM, serum proteins, retinol-binding protein, albumin could be measured. In the present study the effects of the two types of jejunal diets I and II have been compared on the basis of changes in some immune parameters of 36 patients treated with subtotal esophagectomy for malignancy. METHODOLOGY: In randomized controlled trial data of two groups, I. patients with glutamine-rich Stresson Multi Fibre diet (23 patients) and II. patients with Nutrison Multi Fibre glutamine-poor diet (13 patients) were analyzed. Levels of serum proteins were measured by laser nephelometry, CD markers of lymphocytes by flow cytometry, phagocyte activity by chemiluminescence. RESULTS: Level of proteins decreased on the 2nd postoperative day in both groups, then gradually increased postoperatively. In increase of level of serum protein, retinol-binding protein, prealbumin there was no difference between the two groups. CONCLUSIONS: In patients treated with subtotal esophagectomy, the glutamine-rich enteric diet did not result in faster recovery in levels of prealbumin, retinol-binding protein, immunoglobulins and in outcome of patients than the glutamine-poor nutriment.

Endocavital cooling in intraoperative myocardial protection during extracorporeal circulation.

The possible protective effect of endocavital cooling with a balloon left ventricular vent was studied by post cross clamp time rhythm, ECG, DC shock need, dynamics of temperature changes in the interventricular septum, and positive inotropic support requirement in 60 extracorporeal operations (18 aortic valve replacement, 26 aortocoronary bypass and 16 combined procedures) performed by the same team of surgeons with an identical technique and anaesthetic protocol. The results were compared to the data of 60 similar procedures carried out earlier by the same team but without the balloon technique. We conclude that endocavital cooling may have certain additive effects to chemical cardioplegia, especially in cases with left ventricular hypertrophy, multiple coronary stenoses, and in combined procedures.

Protecting effects of intravenous insoluble glycogen treatment on the experimental necrotizing acute pancreatitis of dogs.

BACKGROUND/AIMS: We have studied the effects of insoluble glycogen applied intravenously on the experimental acute pancreatitis of dogs. METHODS: Experimental acute pancreatitis was induced by olive oil injected into the main pancreatic duct. The effects of insoluble glycogen were evaluated histologically and by measurements of levels of amylase, lipase in sera. The binding of endotoxin and secretable phospholipase A2 by insoluble glycogen were tested by isotopically labeled materials. RESULTS: Application of insoluble glycogen had beneficial effects on the experimental acute pancreatitis of dogs. CONCLUSION: The binding capacity on endotoxin and secretable phospholipase A2 could play the main role in the protection offered by insoluble glycogen.
