          Abstract

          Los pacientes con hepatopatía crónica presentan malnutrición en grados variables. Uno de los factores implicados en la malnutrición es la deficiencia del factor de crecimiento insulina tipo I. Objetivo: determinar la relación del factor de crecimiento insulina I y la mal nutrición en pacientes con enfermedad hepática crónica compensada. Materiales y métodos: grupo A, formado por 31 pacientes con enfermedad hepática crónica Child Pugh A y grupo B, 16 controles sanos. A los pacientes se les realizó historia clínica, laboratorio, evaluación antropométrica y se determinó el FCI-1 por técnica de inmunoensayo enzimático. Se aplicó T student con el programa computarizado SPSS y un valor de p < 0,05 fue estadísticamente significativo. Resultados: grupo A: 31 pacientes con enfermedad hepática crónica alcohólica y no alcohólica edad entre 40 y 66 años; grupo B: control 16 sujetos en edades entre 30 y 62 años. En el grupo A se encontró un 41,94% de pacientes normales, 38,71% con sobrepeso, 12,9% con obesidad tipo 1 y 6,45% con déficit. En el grupo B todos los controles eran nutricionalmente sanos. El FCI-1 en el grupo A fue de 47+22ng/ml y en controles 79+33 ng/ml p < 0,05. Conclusión: los niveles sericos de F CI-1 son estadísticamente menores (p < 0,05) en pacientes con enfermedad hepática crónica compensada que en controles sanos, y parecen relacionarse con el grado de malnutrición.

          Patients with chronic liver disease have malnutrition in variable degrees. One of the factors implied in malnutrition is the deficiency of insulin growth factor type 1. Objective: to determine the relationship of insulin-like growth factor 1 and malnutrition in patients with compensated chronic liver disease. Materials and methods: group A: 31 patients with chronic liver disease Child Pugh A and group B: 16 healthy controls. The patients were submitted to a clinical history, laboratory, anthropometric evaluation and IGF-1 was determined by enzymatic immunoassay technique. T student was applied with the SPSS online program and a value of p < 0.05 was considered statistically significant. Results: group A: 31 patients with chronic liver disease, alcoholic and non alcoholic, ages between 40 and 66 years, group B: control 16 healthy individuals, with ages between 30 and 62 years. In group A 41.94% of patients were normal, 38.71% with overweight, 12.9% with obesity type 1 and 6.45% with deficit. In group B all the controls were healthy, nutritionally. IGF- 1 in group A was 47 + 22ng/ml and in controls 79 + 33ng/ml p < 0.05. Conclusion: The serum levels of IFG-1 are statistically lower (p< 0.05) in patients with compensated chronic liver disease than in healthy controls and they seem to be related with the malnutrition degree.

          Nutritional status in cirrhosis. Italian Multicentre Cooperative Project on Nutrition in Liver Cirrhosis.

          Malnutrition frequently occurs in patients with chronic liver disease and may represent a risk factor influencing both short- and long-term survival in these patients. Previously published studies have tended to be confined to alcoholic patients and there are few data on the prevalence of nutritional abnormalities in patients with cirrhosis not of alcoholic origin. Anthropometric measurements and a clinical evaluation of the nutritional status of 1402 patients with cirrhosis (883 males and 519 females) were recorded between January 1988 and 1989 by the Italian Multicentre Cooperative project on Nutrition in Liver Cirrhosis. The origin of liver disease was alcohol-related in 37% of patients. Child-Pugh criteria were used to establish the severity of the liver disease. Patients with cirrhosis exhibited a wide range of nutritional abnormalities. While 29% of females and 18% of males appeared to be overnourished, a significant reduction in fat stores, as estimated by the mid-arm fat area, and/or muscle mass, as estimated by mid-arm muscle area, was observed in 30% of patients with cirrhosis. The prevalence of signs of nutritional depletion increased in both sexes as liver function deteriorated. Mean values for mid-arm fat area decreased by 30% in males and by 40% in females with moderate to severe liver failure (Child-Pugh Classes B and C). The reduction in mid-arm muscle area was more evident in males (17% decrease) than in females (9% decrease). Patients with alcohol-related cirrhosis showed a higher prevalence of malnutrition and had more frequent severe liver impairment (Child-Pugh Classes B and C).(ABSTRACT TRUNCATED AT 250 WORDS)

            Conformational properties of purine-pyrimidine and pyrimidine-purine dinucleoside monophosphates.

            The detailed conformational features and dynamics of heterodinucleoside monophosphates ApU, ApC, GpU, GpC, UpA, CpA, UpG, and CpG have been studied in aqueous solution by high field nuclear magnetic resonance (NMR) spectroscopy. Analysis of the resultant NMR parameters leads to a number of discernible trends throughout the series. Thus the ribose rings of the dimers exist as equilibrium mixtures of C(2')-endo(2E) in equilibrium C(3')-endo(3E) conformers with a proclivity for the 3E pucker in most cases; the C(4')-C(5') bonds of both nucleotidyl units show significant preference (74-96%) for a gg conformation and the dominant conformer (85-89%) about C(5')-O(5') is g'g'. Orientation about the C(3')-O(3') bond is coupled to the ribose conformational equilibrium and the system exists with a bias for the 3Eg- coupled conformation in which the H(3')-C(3')-O(3')-P dihedral angle occupies the narrow range of 33-35 degrees. Dimerization, on the average, causes about 10% increase in gg and g'g' populations and the g-domain becomes increasingly populated about the C(3')-O(3') bond. The ribose equilibrium 2E in equilibrium 3E shifts in favor of 3E upon dimerization, the effect being very conspicuous for the pu-py series (similar to 40 yields 60%) and less noticeable for the py-pu systems (similar to 47 yields 58%), clearly suggesting a correlation between sequence and ribose conformational equilibrium. The temperature and dimerization data for the heterodinucleoside monophosphates show that the transition 2E yields 3E is directly related to XCN changes induced by dimerization and stacking. Analysis of the ribose coupling data shows that the percentage populations of stacked species vary from dimer to dimer with GpC displaying a maximum of 45% stacked population and UpG about 10%. However, in general, the pu-py dimers show a higher preference (27-45%) for stacked conformations than py-pu dimers (10-25%). It is proposed that the pronounced deshielding of H(5') of the 5'-nucleotidyl units upon dimerization is associated with the presence of right-handed stacks (g-g-), whereas the chemical shift trends of H(5') and H(5') of 3'-nucleotidyl units are due to the presence of left-handed stacks (g+g+) in all the dimers. In pu-py dimers, the population of the g-g- species is found to be greater than that of g+g+. Also the population of g-g- stacks in pu-py dimers is generally greater than in their corresponding matched py-pu dimers. Thus the base sequence has not only an explicit effect on the overall populations of stacked species, but also on the handedness of the stacks. The present results further confirm the interdependence of conformational bonds throughout the nucleotidyl framework.
