Impact of Preoperative Total Proteins and Glycated Hemoglobin on Recurrences after Early Colorectal Cancer.

BACKGROUND: The outcome of colorectal cancer is mostly based on TNM classification. There are several factors determining that patients with the same tumoral stage present different outcomes. The nutritional status has been related to the immunological response and may affect the oncologic results. The purpose of this study was to determine if preoperative nutritional parameters may predict the oncologic outcome in patients with early colorectal cancer. METHODS: A prospective observational study of patients undergoing elective surgery for colorectal cancer was performed with stage I. Preoperative nutritional assessment included glycemic and lipid profiles, total proteins, and albumin levels. These parameters were correlated with tumoral recurrence during a follow-up of at least 24 months. RESULTS: During the period of study, 744 patients were operated on and 228 (30.6%) followed the inclusion criteria for this study. Recurrence rate was 5.7% (13 patients). Patients with hypoproteinemia showed a 7.8-fold greater risk of recurrence during the first 24 months after surgery [OR 7.8 (CI95% 1.3-48), p = 0.012]. Patients with glycated hemoglobin levels (HbA1c) > 6.2% showed a 2.3 increased risk of recurrence [OR 2.3 (CI95% 1.1-4.7; p = 0.01]. CONCLUSIONS: Preoperative values of total proteins and HbA1c correlate with the recurrence rate in early colorectal cancer.

Thymoma-associated multi-organ autoimmunity: A case of graft-versus-host disease-like erythroderma complicated by Good syndrome successfully treated by thymectomy.

Thymoma-associated multi-organ autoimmunity disease (TAMA) is a rare paraneoplastic disorder, clinicopathologically similar to graft-versus-host disease (GVHD). Many reported cases follow a difficult course; half of them die from serious infectious diseases subsequent to immunosuppression induced by chemotherapy for unresectable thymoma, or intensive therapies including systemic steroids for complicating autoimmune diseases and GVHD-like symptoms. We report a patient whose skin symptoms were improved subsequently to total thymectomy. The patient also presented with hypogammaglobulinemia, which led to the diagnosis of complicated Good syndrome. Taking account of her immunodeficient condition, antibiotics and i.v. immunoglobulin were administrated promptly on onset of bacterial pneumonia, which was successfully treated. According to a review of the published work, treatments with systemic steroids for skin symptoms have limited effects and may contribute to serious infection. Our case indicates that successful treatment of thymoma itself may lead to the amelioration of the disease. The management priority should be given to the treatment of thymoma and the control of subsequent immune abnormality other than GVHD-like erythroderma.

Hypoproteinemia on the first day of life and adverse outcome in very preterm infants admitted to the neonatal intensive care unit.

OBJECTIVE: We aimed to investigate the relationship between day-1 hypoproteinemia and severe adverse outcome (SAO) in very preterm infants admitted to the neonatal intensive care unit (NICU). STUDY DESIGN: Retrospective study of all patients born from 24 to 31 weeks gestation and cared for in our NICU over an 8-year period. Infants were excluded if the serum protein value on the first day of life was not available. RESULT: A total of 913 patients were included. In all, 14.6% presented with SAO (death or severe neurological injury on cranial ultrasound). Hypoproteinemia (total protein level <40 g l(-1)) on day 1 of life occurred in 19.5 % of all patients. The rate of SAO was 33.7% in patients with hypoproteinemia and 9.9% in those with normoproteinemia (P<0.0001). Logistic and multiple regression analysis confirmed that the association hypoproteinemia-SAO remained significant after adjustment for the other major predictors of outcome present at baseline (odds ratio 3.4; 95% confidence interval 2.1-5.4; P<0.0001). CONCLUSION: Hypoproteinemia was highly associated with SAO in this cohort of critically ill preterm infants. We are unable to explain the link between hypoproteinemia and adverse outcome in our population. This investigation serves as a hypothesis-generating report of a large preterm infants sample, and suggests the need to assess the predictive accuracy for adverse outcome of hypoproteinemia in future prospective studies.

Postoperative hypoproteinemia in cancer patients following extensive abdominal surgery despite parenteral nutritional support.

Determination of the predictors of hypoproteinemia among cancer patients following extensive surgery may enhance their nutritional management and clinical outcome. This study evaluated the predictive factors of postoperative hypoproteinemia among cancer patients following extensive abdominal surgery. An age- and gender-matched case-control study (n = 115) was conducted among cancer patients undergoing extensive (cases; n = 81) and moderate (controls; n = 34) abdominal surgery. Case patients received total parenteral nutrition (TPN), including 3 units of fresh frozen plasma and 200 mL 5% human albumin solution, for 8 postoperative days (POD). Case patients had lower mean total serum protein (TSP) levels throughout POD 8 (F value = 13.81; P = 0.001). Despite TPN, cases had greatest mean (±SD) TSP percent change on POD 1 (-24.6% ± 13.0, vs. -12.6% ± 9.2; P < 0.0001) and did not regain preoperative levels (POD 8: -14.3% ± 12.5 vs. 6.9% ± 13.4; P = 0.006). The likelihood of hypoproteinemia in this group was greatest on POD 3 (OR = 30.57; 95% CI 5.44-171.83). Multivariate regression analyses indicated that the determinants of postoperative hypoproteinemia were age [Adjusted OR (AOR) = 1.04; 95% CI 1.00-1.08), preoperative TSP (AOR = 0.46; 95% CI 0.23-0.92), and extensive surgery (AOR = 2.65; 95% CI 1.01-6.95). Tailored nutritional support, regarding extent of surgery, preoperative TSP, and patient age are needed to deter the occurrence of postoperative hypoproteinemia and consequent adverse surgical outcome among cancer patients.

[Kidney vasculitis connected to cryoglobulinemia IIA and hepatitis B]. / Vascularite rénale dans le cadre d'une cryoglobulinémie mixte associée au virus de l'hépatite B.

We report the case of a 70 years old patient hospitalized for renal insufficiency and deterioration of the general state. The electrophoresis of serum proteins on freezing of agarose reveals the presence of a discrete peak of monoclonal pace on the level of the gammaglobulines identified by serum immunofixation like IgM of the kappa type. The research of the cryoglobulinemia carried out in a laboratory of city was made positive and typified like a monoclonal cryoglobulinemia IgM kappa, thus directing the diagnosis towards a disease of Waldenström. However, the result of the biopsy medullary made exclude any lymphoprolifératif syndrome. The positivity of the serology of hepatitis B justified a second request for study of the cryoglobulinemia, carried out within our laboratory. The cryoglobuline was typified like mixed (IgM kappa monoclonal and IgG polyclonales). This result associated with the immunological assessment and the renal biopsy made retain for our patient the diagnosis of a kidney vasculitis connected to an infection chronicle by the virus of hepatitis B. This observation points out the interest of the preanalytic, analytic and post analytic phases in the study of the cryoglobulinemias. A good technical control is today the only guarantee of the quality of the result of this examination which has large importance in internal medicine in the etiologic assistance with the diagnosis of certain clinical demonstrations.

Hypomagnesemia and hypocalcemia associated with protein-losing enteropathy in Yorkshire terriers: five cases (1992-1998).

OBJECTIVE: To determine clinical and laboratory findings associated with protein-losing enteropathy, hypomagnesemia, and hypocalcemia in Yorkshire Terriers. DESIGN: Retrospective study. ANIMALS: 5 purebred or crossbred Yorkshire Terriers with protein-losing enteropathy, hypomagnesemia, and hypocalcemia. PROCEDURE: Medical records were reviewed for dogs with protein-losing enteropathy, hypomagnesemia, and hypocalcemia. RESULTS: Of 8 dogs with these signs, 5 had Yorkshire Terrier breeding. Common findings were diarrhea, abdominal effusion, leukocytosis, neutrophilia, hypocalcemia (ionized calcium), hypomagnesemia, hypoproteinemia, hypoalbuminemia, hypocholesterolemia, and increased serum activity of aspartate aminotransferase. CONCLUSIONS AND CLINICAL RELEVANCE: Yorkshire Terriers are at increased risk for development of protein-losing enteropathy with hypomagnesemia and decreased ionized calcium concentration. Hypomagnesemia and hypocalcemia may have a related pathogenesis involving intestinal loss, malabsorption, and abnormalities of vitamin D and parathyroid hormone metabolism. Serum electrolyte replacement may be required to avoid neurologic and metabolic problems.

Plasma selenium level in cancer patients.

Selenium has been shown to be a cancer preventive agent. A few studies have shown that increased selenium level is associated with decreased cancer incidence and decreased cancer mortality. The present study was carried out to find out the relationship of selenium level with site, extent of disease, recurrence of disease, histopathological diagnosis, anaemia and serum protein level of cancer patients. Plasma selenium level were studied in 100 patients and mean selenium level of 75.35 ng/ml in cancer patients was significantly less than control values (116.99 ng/ml) in normal healthy individuals (P < 0.003). The strongest association of plasma selenium level and cancer was found in cancer breast (70.50 ng/ml) and gastrointestinal tract (73.05 ng/ml) cancer. Selenium level decreased with the progress of disease and recurrence of disease. No significant association between histopathological diagnosis and selenium level was observed. Anaemia and hypoproteinemia was also not found to be related with selenium level.

Analysis of post-operative hypalbuminaemia: a clinical study.

OBJECTIVE: Analysis of severity, causes and relevance of hypalbuminaemia developing after surgery. SUBJECTS: Patients undergoing elective aortic surgery (n = 11) or minor extra-abdominal surgery (n = 6). METHODS: Serum albumin concentration, blood loss, nitrogen balance and complications were determined until the fifth post-operative day. The contributions of haemodilution, albumin loss, albumin catabolism and redistribution were calculated using existing formula. The relation of hypalbuminaemia to the endocrine-metabolic response was determined. RESULTS: Significant hypalbuminaemia occurred after aortic surgery, in the absence of significant complications. No haemodilution occurred. Analysis indicated that 18% of hypalbuminaemia was caused by blood loss. Only 6% could be attributed to albumin catabolism, despite a significant correlation with the endocrine-metabolic response. Seventy-seven percent of hypalbuminaemia was attributed to albumin redistribution. No hypalbuminaemia occurred after minor surgery. CONCLUSION: Post-operative hypalbuminaemia is a normal finding early after aortic surgery. It is mainly caused by albumin redistribution, not by metabolic changes.

Niveles de proteínas en niños desnutridos menores de 10 años de edad / Protein levels in mal-nourished children under 10 years age old

Durante los meses de marzo a octubre de 1990 se identificaron, mediante un estudio clínico transversal, los niveles de proteínas totales en 50 niños malnutridos de ambos sexos y con edades comprendidas entre 6 meses y 10 años de edad, de los que demandan atención médica en el hospital Dr. Carl Th. George de San Pedro de Macorís, República Dominicana. Se determinó que en el 72 por ciento de estos niños, los niveles de proteína totales eran bajos (620 mg/dl). La hipoproteína fue más común en los niños que en las niñas y en los estados más avanzados de malnutrición. Por último, se corrobora el hecho de que los niños más pequeños, menores del año de edad, son los más propensos a padecer de déficits proteicos importantes. Sugiriendo que la proporción de niñas que nacen con bajo peso es imortante en nuestro medio. Hipoproteinemia, malnutrición, niños, pediatría

Idiopathic hepatic fibrosis in 15 dogs.

Idiopathic hepatic fibrosis was diagnosed by liver biopsy in 15 young dogs, of which nine were German shepherds. Clinical signs included ascites, anorexia, weight loss and hepatic encephalopathy. Erythrocyte microcytosis was a consistent clinical feature, and clinical chemistry generally revealed hypoproteinaemia and high serum activities of alkaline phosphatase and, to a smaller extent, alanine aminotransferase. Fasting blood ammonia and serum bile acid concentrations were increased in most dogs examined, and all the dogs tested had prolonged retention of sulfobromophthalein at 30 minutes. Multiple acquired portosystemic shunts were revealed by laparotomy and/or portography. Non-inflammatory fibrosis was present to different degrees in all the dogs' livers, and on the basis of its predominant location these were classified as having central perivenous fibrosis, diffuse pericellular fibrosis or periportal fibrosis. The response to symptomatic treatment and anti-fibrotic therapy with glucocorticosteroids or colchicine was variable. Seven dogs died or were euthanased shortly after diagnosis, but one dog survived two-and-a-half years, and three dogs were still alive more than four years after the initial diagnosis.

[Therapy-refractory primary intestinal lymphangiectasis]. / Therapierefraktäre primäre intestinale Lymphangiektasie.

A 20-year-old man with severe physical weakness (from which he soon recovered spontaneously) was found to have hypoproteinaemia and lymphocytopenia (768/microliters). Ten years later, after having been free of symptoms in the meantime, oedema, ascites and abdominal pain occurred, associated with loss of physical capacity. Enteric loss of protein (alpha 1-antitrypsin clearance increased about thirtyfold) with a total serum protein concentration of only 3.7 g/dl, as well as histological evidence of lymphangiectasia of the small and large intestines provided the diagnosis of primary intestinal lymphangiectasia. In the course of the disease cholelithiasis and (after treatment with tranexamic acid) thrombosis of the axillary vein occurred. No treatment has been of any avail and the patient has been unable to work for three years.

Albumin supplementation in the critically ill. A prospective, randomized trial.

Albumin replacement to correct hypoalbuminemia in critically ill patients has been controversial. This study was a prospective, randomized trial of 25% albumin administration in 40 hypoalbuminemic (serum albumin, less than 25 g/L [2.5 g/dL]), critically ill patients. The treatment group (18 patients) received 25% albumin supplementation to achieve and maintain serum albumin levels of 25 g/L (2.5 g/dL) or greater, while the nontreatment group (22 patients) received no concentrated albumin. There was no clinical benefit from albumin therapy when assessing mortality (39% vs 27%, treatment vs control) or major complication rate (89% vs 77% of patients). There were also no significant differences in length of hospital stay, intensive care unit stay, ventilator dependence, or tolerance of enteral feeding, despite significant elevations of albumin in the treatment group. The costly use of exogenous albumin as treatment for hypoalbuminemia in this patient population does not appear to be justified.

The outcome of surgical treatment as related to the response of the serum albumin level to nutritional support.

Selected nutritional parameters were studied in critically ill surgical patients maintained by parenteral-enteral nutritional support to delineate the nutritional deficits and relate the course of these patients to the nutritional status. Twenty-one of 34 patients had albumin levels of less than 3.5 grams per cent upon admission, and the albumin levels decreased even further after admission. The patients with traumatic injuries had the greatest loss in body weight and urinary nitrogen excretion. Although such large numbers of these patients had depressed serum albumin levels, the survivors were able to increase the serum albumin level to 3.5 grams per cent with intense nutritional support, whereas those not surviving such support were not able to increase the serum albumin level. The response of the serum albumin level to nutritional support is a good indicator as to the same factors preventing survival and effective use of the nutritional elements.
