Sixty-three patients with duodenal ulcer were operated upon with selective proximal vagotomy (SPV). In 34 patients the vagotomy was combined with a pyloroplasty (PP). Before and after operation the acid secretion was investigated after Histalog (50 mg) stimulation. Insulin tests were performed 4-6 weeks, 1 year, and 3 years after operation. One and 3 years after operation ESR, Hb, SeFe, Protein, Albumin, Calcium, and Alkaline phosphatases were determined. One patient developed gastric retention and 3 got relapses during the first year. At reoperation, overlooked vagal branches in the region of the cardia were found. Five patients developed a minor anemia and 2 sideropenia, which is less than after truncal vagotomy and PP. The operation caused a highly significant reduction in acid output after Histalog stimulation. The postoperative insulin test was graded according to Bachrach: 49 were complete, 12 extensive but incomplete, and 2 incomplete. During the second hour after stimulation a probably significant increase was noted in the acid output between the postoperative and the one-year investigation. Between the one- and the three-years tests a significant increase was found during the first hour after insulin stimulation and a probably significant increase during the second hour. The gastric emptying of a composite fluid test meal was significantly faster after operation than before in patients where the insulin stimulation did not give rise to any acid production.

The erythrocyte sedimentation rate is one of the most frequently used laboratory tests in clinical medicine. The sedimentation rate is determined by the aggregation of erythrocytes, in which plasmatic and erythrocytic factors are involved. Plasmatic factors include high-molecular proteins such as fibrinogen, globulins (immunoglobulins, especially IgM, alpha 2-globulins) and immune complexes (e.g. cryoglobulins). Albumin, a smaller protein with a spherical structure, decreases erythrocyte aggregation. Erythrocytic factors play an equally important role. Anemia and macrocytosis lead to an increase in sedimentation rate, whereas the presence of abnormal red cell shapes and deformability decrease the sedimentation rate. The diversity of factors involved often renders the interpretation of sedimentation rates difficult. Normal values for females are higher than for males and increase with age. The sedimentation rate is not useful for screening of asymptomatic subjects, e.g. the detection or exclusion of a malignant tumor. It is appropriate in monitoring the course of diseases such as arteritis temporalis or polymyalgia rheumatica. The sedimentation rate should therefore be used in a more restrictive and selective manner.

Tuberculin tests were carried out on 400 adults with established tuberculosis and 200 apparently healthy adults. There was no significant difference in the tuberculin reactivity amongst those tuberculous patients who were clinically in a poor state and the control group. On the other hand the former reacted less than those tuberculous patients whose general physical state was normal and the difference was significant. Overall 23.75% of the tuberculous patients had negative reactions. Women were less reactive than men. The tuberculin allergy decreased with both age and the extent of tuberculous disease. There was no significant variation in the diameter of the skin test as a function of the number of Koch's bacilli. In tuberculous lymphadenopathy we noted a stronger allergy than in tuberculous disease of other parts of the body. There is a positive correlation between the tuberculin reaction and the Serum Albumin level. Associated morbidity (eg infestations, anaemia, malaria, intestinal schistosomiasis and malnutrition) reduce the tuberculin reaction. These observations reduce the diagnostic value of the intra-dermal tuberculin reaction in our environment.

Hematological, biochemical, histoenzymological, and histopathological changes in serum and tissues were studied in chickens during outbreaks of nephritis. Hematological studies revealed normocytic-normochromic anemia characterized by increased total erythrocyte counts, hemoglobin, packed cell volume, and erythrocyte sedimentation rate. Albumin-to-globulin ratio and sodium levels in serum, glucose in blood, and alkaline phosphatase and glucose-6-phosphatase in liver and kidneys were decreased. Glutamate pyruvate transaminase, uric acid, non-protein-nitrogen, and potassium levels in serum were increased. No significant change in the calcium, phosphorus, and total protein levels in serum was observed. These changes were directly related to the severity of the nephritis.

The nephrotic syndrome is a consequence of urinary loss of intermediate-sized plasma proteins and the resulting homeostatic responses to those losses. Plasma protein composition is changed greatly. Pathophysiologic changes are a consequence of the nature of the proteins lost and of the proteins that are increased in plasma to replace them. Plasma oncotic pressure (pi) falls because of the replacement of relatively small plasma proteins by larger ones. Decreased pi increases transudation of fluid into the interstitium and favors edema. This is exacerbated by causing renal insensitivity to atrial natriuretic factor (ANF), primary renal sodium retention, and plasma volume expansion. Many proteins lost in the urine, such as erythropoietin and IgG, are not defended by increased synthesis. Their loss may result in reduced immunity, anemia, and endocrinopathies. Albumin synthesis can be increased by dietary protein augmentation; however, urinary protein losses also increase, offsetting any palliative effect of increased albumin synthesis on albumin stores. The synthesis of many other proteins secreted by the liver is also increased, causing an elevation in plasma levels of several large proteins, including lipoproteins and elements of the coagulation cascade. This results in hyperlipidemia and, in conjunction with the urinary loss of smaller proteins that impede coagulation, a hypercoagulable state. Lipoprotein catabolism is also reduced as a consequence of proteinuria contributing to increased lipid levels.

Stewart in 1983 (Can J Physiol Pharmacol 1983: 61: 1444) reintroduced plasma buffer base under the name "strong ion difference" (SID). Buffer base was originally introduced by Singer and Hastings in 1948 (Medicine (Baltimore) 1948: 27: 223). Plasma buffer base, which is practically equal to the sum of bicarbonate and albuminate anions, may be increased due to an excess of base or due to an increased albumin concentration. Singer and Hastings did not consider changes in albumin as acid-base disorders and therefore used the base excess, i.e., the actual buffer base minus the buffer base at normal pH and pCO2, as measure of a non-respiratory acid-base disturbance. Stewart and followers, however, consider changes in albumin concentration to be acid-base disturbances: a patient with normal pH, pCO2, and base excess but with increased plasma buffer base due to increased plasma albumin concentration get the diagnoses metabolic (strong ion) alkalosis (because plasma buffer base is increased) combined with metabolic hyperalbuminaemic acidosis. Extrapolating to whole blood, anaemia and polycytaemia should represent types of metabolic alkalosis and acidosis, respectively. This reveals that the Stewart approach is absurd and anachronistic in the sense that an increase or decrease in any anion is interpreted as indicating an excess or deficit of a specific acid. In other words, a return to the archaic definitions of acids and bases as being the same as anions and cations. We conclude that the acid-base status (the hydrogen ion status) of blood and extracellular fluid is described in terms of the arterial pH, the arterial pCO2, and the extracellular base excess. It is measured with a modern pH-blood gas analyser. The electrolyte status of the plasma is a description of the most important electrolytes, usually measured in venous blood with a dedicated electrolyte analyser, i.e., Na+, Cl-, HCO3-, and K+. Albumin anions contribute significantly to the anions, but calculation requires measurement of pH in addition to albumin and is usually irrelevant. The bicarbonate concentration may be used as a screening parameter of a nonrespiratory acid-base disturbance when respiratory disturbances are taken into account. A disturbance in the hydrogen ion status automatically involves a disturbance in the electrolyte status, whereas the opposite need not be the case.

Erythropoietin secretion was evaluated in the anaemia of chronic disorders in elderly patients, since it has been shown that this secretion is impaired in adults. We looked for a possible role of inflammatory cytokines: tumor necrosis factor-alpha (TNF alpha) and interleukin-1 beta (IL-1 beta) on erythropoietin production. The influence of nutritional status on the anaemia was also investigated. Erythropoietin secretion was significantly increased in elderly patients with anaemia of chronic disorders (ACD) and inversely correlated with haemoglobin concentrations in infectious and inflammatory diseases. Plasma TNF alpha levels were significantly enhanced only in cancerous patients, but no correlation could be established between TNF alpha and erythropoietin or haemoglobin. No noticeable increase of IL-1 beta levels was observed in ACD. These findings suggest that systemic TNF alpha or IL-1 beta are not involved in the erythropoietin response to ACD. Albumin levels were decreased in anaemic patients. Further investigations of the effects of a nutritional supplementation in elderly patients with ACD may be of interest.

Clinical, anthropometric, hematologic, and biochemical variables, evaluated immediately before starting nutritional treatment, were related to survival in 76 terminal-cancer patients with irreversible bowel obstruction receiving home parenteral nutrition. At baseline, abnormally low values were observed in the following percentages of patients: 40.8% for body mass index, 59.2% for serum albumin, 84.2% for hemoglobin, 48.7% for lymphocyte count, and 60% for serum cholesterol. Survival on home parenteral nutrition ranged between 6 and 301 d, with a median of 74 d. Hemoglobin, serum albumin and serum cholesterol were lower in patients with a survival of less than 3 mo. With regard to Karnofsky performance status, median survival times were 63 d for a score below or equal to 50 and 128 d for a score between 60 and 70. Albumin and a Karnofsky score above 50 (but not age, weight, body mass index, lymphocyte count, or cholesterol) emerged (with a positive sign) as predictors of survival. In conclusion, terminal-cancer patients with irreversible bowel obstruction are often malnourished, showing a high prevalence of anemia and hypoalbuminemia. Survival differs widely and can be predicted only to a limited extent from initial values of serum albumin and Karnofsky performance status.

Cardiovascular disease is one of the most important causes of morbidity and mortality in children with end-stage renal failure. Chronic inflammation and malnutrition have been suggested to be risk factors for cardiovascular disease. However, to date, biomarkers of inflammation have not been well studied in children. The aim of this study was to investigate the relation between chronic inflammation and cardiovascular risk factors in children on hemodialysis therapy. Twenty-seven patients on hemodialysis (14 girls, 13 boys) of mean age 15.3 +/- 2.4 years and 20 healthy children (13 girls, 7 boys) of mean age 14.3 +/- 2.7 years were included the study. C-reactive protein (CRP), albumin, prealbumin, transferrin, ferritin, and fibrinogen were measured as the markers of inflammation. The levels of CRP, ferritin, and erythrocyte sedimentation rate among hemodialysis patients were significantly higher than those of control subjects (P < .001 for all). Albumin and transferrin levels were found to be lower than those of control group (P = .02 and P < .001, respectively). CRP levels were negatively correlated with albumin, prealbumin, apoprotein A1, HDL, and hemoglobin levels, and positively correlated with erythropoietin/Htc ratios. This study suggests that hemodialyzed children are exposed to chronic inflammation. In addition, CRP may be an indicator of chronic inflammation related to cardiovascular risk factors, such as malnutrition, dyslipidemia, and anemia. In conclusion, we suggest that the risk of cardiovascular disease could be reduced by defining markers of chronic inflammation and malnutrition in hemodialyzed children and by taking necessary measures at an early stage.

A male patient with chronic bloody stool was diagnosed as juvenile polyposis at the age of 28. He had thirty to forty colonic polyps and some were removed endoscopically, while gastric polyps were too numerous to intervene. As the polyposis advanced gradually, the patient developed intractable anemia and serious hypoproteinemia. Albumin scintigram revealed protein losing gastropathy due to progressive gastric polyposis. Total gastrectomy was carried out at the age of 34 and the patient has achieved remarkable and sustainable improvement.
