Nutritional status of patients hospitalised in Poland.

AIM: Screening and extended assessment of the nutritional status of patients on admission and on discharge from hospital were carried out. DESCRIPTION: The studies were carried out in four teaching hospitals, four provincial hospitals and four county hospitals in Poland. SUBJECTS: Screening examinations were carried out for 3310 randomly selected patients (every 10th patient admitted to hospital, including 1916 female cases aged from 16 to 92 y and 1394 male patients aged from 16 to 100 y). Extended examinations were carried out on 210 patients aged from 16 to 87 y (including 122 female and 88 male). MAIN ASSESSMENT PARAMETERS: Anthropometric (height, weight, body mass index (BMI), waist-to-hip ratio (WHR), arm circumference) and biochemical indices (erythrocyte count, haemoglobin concentration, white blood cell count, blood lymphocyte count and serum albumin serum concentration). The extended examinations included determination of antioxidant vitamins (A, C, E), vitamin B(12) and folic acid. RESULTS: On admission to hospital, 10.43% of the patients surveyed had a BMI below 20 kg/m(2), in 20.74% of patients serum albumin concentration was below 3.5 g/dl, indicating possible protein energy malnutrition. In addition, 21.02% had lymphocyte count below 1.5 x 10(3)/mm(3). During hospitalisation, deterioration in the nutritional status of the patient population occurred. On discharge from hospital, the percentage of patients with BMI < 20 kg/m(2) increased to 11.21% and the percentage with low blood albumin (<3.5 g/dl) increased to 28.57%. On admission, vitamin C deficiency was present in 51.8% of patients, folic acid deficiency in 32%, vitamin E deficiency in 10%, vitamin B(12) deficiency in 6.8% and vitamin A deficiency in 1.4%. Vitamin deficiencies were present equally in malnourished, overweight and obese patients. CONCLUSIONS: In patients admitted to hospitals in Poland, malnutrition risk demonstrated by BMI was observed in 10.43% of patients. On the basis of biochemical indices, increased nutritional risk was demonstrated in 21% of patients. Vitamin malnutrition was seen in the majority of patients. A significant correlation between weight, BMI, arm circumference, blood lymphocyte count and the number of days spent in hospital was observed.

[Dynamic of IL-6 and IL-8 concentrations in patients after surgery treated with total parenteral nutrition].

Exaggerated cytokines productions and development of systemic inflammatory response (SIRS) is the most common cause of postoperative complications and death after major abdominal surgery. The present study was conducted to investigate alterations in systemic production of interleukin-6 (IL-6) and interleukin-8 (IL-8) after total parenteral nutrition (TPN) in surgical patients. Plasma concentrations of IL-6 and IL-8 were measured in 22 patients (10 treated with TPN and 12 without TPN) before major surgery and on the days 1, 3, 7, 10 and 14-16 after, by ELISA test (indications for surgery: stomach, pancreatic and colon carcinoma, complications of IBD and acute pancreatitis). There were no differences between preoperative levels of IL-6 and IL-8 in the examined groups of patients. The highest (on the days 1, 3, 7, 10: 268.3 (p = 0.002), 41.9 (p = 0.03), 122.6 (p = 0.009), 29.3 (p = 0.03) pg/ml respectively) and longer lasting significantly elevated level of IL-6 was observed in the group of patients after major surgery without TPN. In the group of patients received TPN (with glutamine) there was a significantly increased but in comparison with group of patients without TPN, significantly lower level of IL-6 on days 1 and 7 (103.4 and 34.7 pg/ml respectively, p = 0.01). There was no significant change in postoperative concentration of IL-8 after major surgery in the group of patients treated with TPN. The level of IL-8 was significantly elevated (p = 0.01) in the group of patients without TPN on day 1 and 3 following surgery. The IL-8 level in the TPN group vs. group of patients without TPN was significantly lower on day 1 after surgery. After TPN concentration of cholesterol was significantly higher and CRP level significantly lower. We conclude that TPN improved immunological response to major surgical trauma by reduction of the inflammatory response.

[Cellular immunity changes after total parenteral nutrition enriched with glutamine in patients with sepsis and malnutrition].

The influence of glutamine on human immune system is multidirectional but the exact changes still remain unclear. In this study the effect of total parenteral nutrition (TPN) enriched with glutamine on some selected immunological and nutritional parameters was examined in twelve surgical patients with sepsis and malnutrition. The reason for glutamine supplementation was lack of clinical improvement after standard TPN. All patients received TPN enriched with glutamine for 10 days. Phenotypic analysis of peripheral blood mononuclear subsets (CD4, CD8, CD16, CD56, HLA-DR) were measured before, during (on days 2, 4, 6) glutamine administration and two days after (day 12) glutamine withdrawal. Simultaneously some nutritional parameters were assessed. The number and percentage of CD4, CD16, CD56 mononuclear subsets increased significantly on day 2 and stayed on the same level during observation (with exception in CD4 on day 6, 12 and CD56 on day 4). No significant differences in CD8 and HLA-DR number and percentages were observed after TPN enriched with glutamine. BIA examination revealed on days 2 and 12 significant decrease of total body water and significant increase of body cell mass, intracellular water on day 12. It was correlated with significant higher total lymphocytes count and significantly higher total protein, serum albumin, transferrin, cholesterol and CRP concentration. Results demonstrated that TPN supplemented with glutamine improved rapidly some immunological and nutritional parameters in surgical, malnutrition patients with sepsis.

[Value of chosen immunologic parameters in assessment of surgical trauma extent].

The subject of study was to assess the sensitivity of chosen immunological parameters in the extension of the post operative trauma. Two groups of patients were studied: group I--12 patients underwent laparoscopic cholecystectomy (ChL), group II--18 patients underwent conventional cholecystectomy (ChK). We compared changes in the concentration of interleukin 1 receptor antagonist (IL-1ra) and interleukin 6 (IL-6) in blood. Blood tests were taken before operation and 1, 3, 7, 10 days after operation. Levels of IL-1ra and IL-6 were determined by ELISA. It was stated that cholecystectomy (ChK, ChL) evoked statistically significant changes in the value of chosen immunological parameters. In comparison with ChK the ChL evokes significant but smaller and shorter lasting changes in tested parameters of the immunological response that indicates that ChL is less invasive surgical procedure. The IL-1ra and IL-6 concentration changes constitute a very sensitive markers of immunological response to surgical trauma. The value of IL-1ra and IL-6 changes in immunological response monitoring, especially in the patients with postoperative complications requires further investigations.

[Clinical evaluation of amino acid solution].

Glutamine, a conditionally essential amino acid, is important for immune function. It is now being formulated for incorporation in to total parenteral nutrition (TPN). The aims of this study were to examine the effect of glutamine administration on clinical status, body composition, protein synthesis and immune function in critically ill patients with sepsis. Eleven patients were included into the study. Seven of them have been on conventional TPN for 8-63 days without significant clinical and nutritional improvement. Glutamine supplemented TPN was implemented for 10 subsequent days. Before, during and after the study venous blood samples were taken for the cellular immunity examination, and for the measurement of plasma albumin, transferrin and triglycerides levels. Nitrogen balance was calculated every day during the study. No side effects were noted. Patients receiving amino acid solution revealed improved nitrogen balance, body composition and body water distribution. Plasma proteins concentrations and immunological indices significantly increased during ten days TPN with Glamin. We confirm the beneficial effects of amino acid solution-supplemented TPN on nitrogen balance, plasma proteins, and immune status of critically ill patients.

[Computer program "PANCREAS"].

Contemporary computer technology allows precise and fast large database analysis. Widespread and common use depends on appropriate, user friendly software, usually lacking in special medical applications. The aim of this work was to develop an integrated system designed to store, explore and analyze data of patients treated for pancreatic cancer. For that purpose the database administration system MS Visual Fox Pro 3.0 was used and special application, according to ISO 9000 series has been developed. The system works under MS Windows 95 with possibility of easy adaptation to MS Windows 3.11 or MS Windows NT by graphic user's interface. The system stores personal data, laboratory results, visual and histological analyses and information on treatment course and complications. However the system archives them and enables the preparation reports of according to individual and statistical needs. Help and security settings allow to work also for one not familiar with computer science.

[Total parenteral nutrition. History. Present time. Future].

Total parenteral nutrition (TPN) has been available for only 30 years. However, history in this field goes back more than 350 years with the first landmark being the description of general blood circulation by William Harvey in 1628. His discovery is the anatomical basis for intravenous infusions. Many investigations were performed during the following centuries showing that solutions containing electrolytes and glucose could be given intravenously in man. The accumulated knowledge of protein metabolism formed the basis for studies on intravenous nutrition with protein hydrolysates, peptides and amino acids. The observation in the late 30-s by Robert Elman that amino acids in the form of protein hydrolysate could be safely administered intravenously in man was the first major step toward TPN. During the following years, major efforts were made to find methods to prepare infusion solutions with a high energy content and low osmotic pressure. The most realistic alternative seemed to be fat in the form of an emulsion. Many studies of a large number of various fat emulsions were made however, all of these emulsions caused severe adverse reactions in man. The first safe fat emulsion, intralipid, was made available in the early 60s. This was the second major step toward TPN. It was then no problem to include vitamins, electrolytes and trace elements in the fat emulsions and the solutions of amino acids and glucose. A few years later it was shown that a central venous catheter could be used to administer the infusion fluid intravenously. Many clinical investigations and reports have shown that the newly developed intravenous nutritional regimens are adequate alternatives to the ordinary diet. In this way it has been possible to maintain or obtain a good nutritional condition in most situations when oral or tube feeding can not be used. TPN has been shown to be of very great clinical importance to prevent and treat starvation often related to high morbidity and mortality.

[Parenteral nutrition in postoperative period].

Results of surgical procedures in malnutrished patients are worse than in well-nutrished patients. Perioperative nutritional treatment lead to diminished percentage of postoperative complications and mortality. Authors presents the influence of early postoperative enteral nutrition in 35 malnutrished patients on body composition and anthropometrical and biochemical parameters of their nutritional status. Results shows that enteral nutrition in postoperative phase can decrease catabolic effect of surgical treatment.

[Cellular immunity in patients with non-specific inflammatory bowel disease for an extended period after surgery].

The study was aimed at investigating the expression of HLA-DR, CD4, CD8, CD56 surface antigens on peripheral blood lymphocytes in patients with non-specific inflammatory bowel diseases in the period of 1-5 years after the surgical procedure. The percentage of rosette forming T-cells in the theophylline test and skin reaction to mycotic and bacterial antigens were assessed simultaneously. The experiment included group of 12 patients (aged 5-55), treated surgically because of Crohn's disease or ulcerative colitis. The lymphocytes' surface antigens were examined by means of monoclonal antibodies and the APAAP procedure. Significantly increased (p < 0.001) percentage of lymphocytes with HLA-DR surface antigens and significantly decreased (p < 0.002) percentage of lymphocytes with CD8 surface antigens were observed in patients with non-specific inflammatory bowel diseases. In 6 of 12 patients the skin test results were negative. The clinical symptoms, which may suggest the maintaining inflammation of the intestinal mucosa were found in 50% of patients examined after surgical procedure because of Crohn's disease. The results suggest there are significant disturbances of cellular immunoreactivity parameters in patients with non-specific inflammatory bowel diseases. It may be one of the causes, which maintain the chronic inflammation of the intestinal mucosa and favour disease recurrence. The cellular immunoreactivity disturbances demonstrated in this study may be the result of the still persisting intestinal mucosa. Inflammation, in spite of deficiency of synonymous clinical symptoms indicating the disease recurrence.

[Selected cellular immunity parameters in patients with Lesniowski-Crohn disease].

The study was aimed at investigating the expression of HLA-DR, CD4, CD8, CD56 and CD16 surface antigens on peripheral blood lymphocytes in patients with Crohn's disease. The percentage of rosette-forming T-cells in theophylline test was assessed simultaneously. The experiment at group consisted of 18 patients (aged 16-66) of long standing Crohn's disease history, being in the remission period and not treated by steroid antiinflammatory drugs. The percentage of lymphocytes with HLA-DR, CD4, CD8, CD56 and CD16 surface antigens was examined by means of the monoclonal antibodies (DAKO), and the APAAP procedure. The immunological test included also an assessment of the number of T-cells forming active (ARFC) and total (TRFC) rosettes in the theophylline test. Significantly increased (p < 0.001) percentage of lymphocytes with HLA-DR surface antigens was observed in patients with Crohn's disease. The percentage of lymphocytes with CD4, CD8, CD56 and CD16 surface antigens did not differ significantly from the control group, although the tendency for increase in the percentage of lymphocytes with CD8 surface antigens was clearly marked. The ratio of lymphocytes with CD4 to CD8 surface antigens and the number of T-cells forming active and total rosettes were significantly lower (p < 0.05) in patients with Crohn's disease. In 10 of 18 patients the number of T-cells forming active and total rosettes was lower than 500 cells in 1 mm3 peripheral blood. In addition particular notice should be given to the fact that no T-cells reaction to theophylline was obtained in patients' group. The results suggest significant cellular immunoreactivity disturbances which may be the result of the persisting intestinal mucosa's inflammation in patients with Crohn's disease being in the remission period. The studies of peripheral blood lymphocytes with HLA-DR surface antigens may have significance in Crohn's disease's clinical monitoring.

[Evaluation of the effectiveness of cefazolin++ (Kefzol) in preventing infections in patients after abdominal surgery].

The purpose of the work as an assessment of the effectiveness of cefazolin (Kefzol) in preventing infections in patients after abdominal surgery. The prospective studies included 200 patients, out of whom in 100 patients in the studied group Kefzol was administered prior to and for 24 hours after operation, while in 100 patients in the control group no prevention was used. The percent of infections in the studied group was lower in comparison to the control group (9% vs 25%, p < 0.01). A statistically significant reduction was obtained of wound infection per cent from 19% in the control group to 7% in the studied group, including a reduction from 14.3% to 3.1% after operations on the gall bladder and bile ducts, and from 18.2% to 11.1% after gastroduodenal operations. The per cent of wound infections after appendectomy was 5.9% in the patients from the studied group receiving prophylactically Kefzol with metronidazole, and 20.6% in the patients from the control group. Bacteriological investigations, demonstrated that 87.5% bacterial strains were susceptible to cefazolin. In the authors' opinion cefazolin (Kefzol) is effective in the prevention of purulent complications, and the reduction of the per cent of infections causes lowering of treatment cost.

Poliovirus type 1 enters the human host through intestinal M cells.

It was demonstrated by electron microscopy that after in vitro incubation of human Peyer's patches with poliovirus type 1, either Sabin or Mahoney strain, poliovirus particles adhere specifically to and are endocytosed by intestinal epithelial M cells. These findings suggest that M cells in humans are the site of poliovirus penetration of the intestinal epithelial barrier.
