Under the current situations we have increasing opportunities to manage the patients with posthepatitis and/or congestive liver dysfunction. In order to prevent postoperative hepatic failure we described perioperative management for those patients. For this purpose, the major point is the selection of appropriate operative methods which reduce operative invasions and have sure efficacy. In order to decide operative methods, we have to grasp the functional reserve of dysfunctional liver. We have no effective methods to estimate the functional reserve, but our data suggested that serum cholinesterase level at the preoperative states might demonstrate prognostic significance. The others are managements of postoperative cardiopulmonary distress and infection. It goes without saying that preoperative improvement of anemia and poor nutrition.

Exacerbating factors of tuberculosis were evaluated from the viewpoint of intractability of the disease including the effectiveness of chemotherapy by comparing patients with intractable tuberculosis and those with nonintractable tuberculosis. Of the patients aged 30 years or above admitted to our hospital for the initial episode of tuberculosis, 42 patients with intractable tuberculosis and 247 controls were compared. No difference was observed between the two groups in life-style factors such as smoking, drinking, and living alone or complications such as diabetes mellitus and cerebrospinal diseases. In the refractory group, a poor general condition with fever and body weight losses on admission, massive discharge of tubercle bacillus, and delayed diagnosis and treatment were frequently observed. Also, patients with a lymphocyte count of 500/mm3 or less such as those with anemia, hypoproteinemia/hypoalbuminemia, high LDH and CRP levels, and a low cholinesterase level were significantly more frequent, and resistant bacteria were detected more frequently in this group.

The authors monitored, for a period of 12 months, anemia-, nutrition-, and free radical-related parameters and the rHuEPO dose required to maintain target hemoglobin (Hb) in 20 patients with chronic renal failure. Ten patients each were randomized for treatment by either acetate-free biofiltration (AFB) or low-flux hemodialysis (HD). At baseline, Hb levels were 102+/-2 (AFB) vs. 98+/-2 g/L (HD) (not significant difference, NS), the rHuEPO dose was 4050+/-976 vs. 5100+/-1538 lU/week (NS). Compared with baseline and with HD, lower rHuEPO doses were required during AFB at months 8, 9, 10 and 11, and 12 when they were 2100+/-510 (AFB) vs. 6000+/-1153 (HD), p=0.008. Prealbumin, transferrin and cholinesterase levels rose in the AFB group. Kt/V, albumin, transferrin saturation, aluminium, bicarbonate in serum, superoxide dismutase and glutathione peroxidase in erythrocytes, and malondialdehyde and antioxidant capacity in plasma did not differ between the AFB and HD groups. In terms of anemia control, AFB using an AN69 membrane was found to be more advantageous than low-flux HD, AFB improves some nutritional parameters. The compared methods do not differ in their effect on lipid peroxidation and the antioxidant system.

The effect of malignant tumor growth on host's megakaryocytopoiesis and platelet production was studied in mice bearing transplantable Dalton's lymphoma. Tumor growth was paralleled by thrombocytosis, neutrophilia, and anemia. Platelet 51Cr half-life was normal but incorporation of 75Selenomethionine into circulating platelets was significantly enhanced in the tumor bearers suggesting stimulated thrombopoiesis while platelet life span remained unchanged. Megakaryocytes and their precursors, the small acetyl cholinesterase positive cells, were found in increased numbers in the bone marrow (BM) and particularly in the spleen where five to eight-fold rise was observed at the log phase of tumor growth. In addition, a remarkable increase in the number of megakaryocyte progenitors (CFU-MK and MK CFU-S) was observed both in the BM and spleen. Stimulation of these progenitors was more pronounced in the spleen than in the marrow, and the change was noticeable even from the third day of tumor bearing. Therefore, the results suggest that thrombocytosis associated with the growth of this experimental lymphoma was due to accelerated platelet production following stimulated megakaryocytopoiesis especially in the spleen.

The prevalence of anemia increases with age and is frequently multifactorial. We postulated that malnutrition contributes to anemia in the elderly and is underdiagnosed. Our objective was to analyze the prevalence of anemia and its association with nutritional status in a hospitalized geriatric population. Included in this retrospective cohort study were 186 consecutive patients admitted in 1997 to a geriatric unit of a university hospital. We compared hematological and chemical blood tests routinely performed upon admission in patients with anemia (hemoglobin <120 g/l) and without anemia (hemoglobin > or = 120 g/l). Using these admission parameters, we defined a multiparameter score of malnutrition by low lymphocyte counts, decreased values of albumin, cholesterol, transferrin, cholinesterase, and zinc, iron deficiency by low transferrin saturation and normal C-reactive protein, and inflammation by increased C-reactive protein and high transferrin saturation. Of the 186 patients, 82 (44%) met the criteria for anemia on admission. In univariate analysis, patients with anemia differed significantly from patients with normal hemoglobin exhibiting lower serum values of albumin, iron, transferrin, cholesterol, cholinesterase, zinc, transferrin saturation, and lymphocyte count and higher C-reactive protein levels. Using a multiparameter score, anemia correlated significantly with parameters of malnutrition (P=0.0001) but not with iron deficiency (P=0.5) or with inflammation (P=0.08). In a multivariate logistic regression model, anemia was significantly associated with serum albumin (RR: 1.138; 95% CI: 1.056-1.227; P=0.0007), cholinesterase (RR: 1.387; 95% CI 1.122-1.714; P=0.0025), and transferrin saturation (RR: 1.05; 95% CI: 1.012-1.09; P=0.009). We conclude that malnutrition may play an important etiologic role in anemia in the elderly.

The recent development of acetylcholinesterase inhibitors to treat patients with Alzheimer's disease has increased interest in the use of biochemical markers for the early detection and diagnosis of dementia, but only the measurement of the protein 14-3-3 in cerebrospinal fluid (CSF) to help diagnose sporadic Creutzfeldt-Jakob disease has become accepted clinical practice. CSF concentrations of tau protein and beta-amyloid peptide 42 have been widely investigated as potential diagnostic tests for Alzheimer's disease, but neither has shown sufficient sensitivity and specificity for clinical use. Preliminary investigations suggest that beta-amyloid peptide 42 may be useful in monitoring disease progression, but this needs to be verified. In addition, biochemical investigations may help to identify the small number of patients with treatable causes of dementia such as hypothyroidism and vitamin B12 deficiency, as well as any other compounding condition such as anaemia or diabetes mellitus that increase morbidity.

Ten to twenty percent of the offspring of mothers suffering from myasthenia gravis (MG) also develop transient neonatal MG, since maternal antibodies are able to cross the placenta. We report the course of two newborns of a mother with MG and a healthy father. The first pregnancy was complicated during the 3rd trimester by a hydramnion. The newborn presented with generalized muscle weakness, respiratory distress, weak sounding, anaemia, and poor sucking. Mechanical ventilation was necessary. Confirmation of the diagnosis was achieved by the result of repetitive muscle stimulation, showing a typical decrement in the EMG, and measurement of serum antiacetylcholin receptor antibodies. For 3 months, the infant was treated with neostigmin (cholinesterase inhibitor). After 26 days of hospitalization, the patient was released and followed up regularly. Myasthenic symptoms completely resolved. Side effects of the treatment were not observed. The course of the second pregnancy was normal. This second newborn was healthy. Our case report is remarkable for the very different presentation of two children of the same mother with MG during pregnancy and after delivery, with one child developing severe transient neonatal MG, initially requiring intensive care unit (ICU) treatment followed by quick recovery, and one child being healthy. We also present a score for monitoring the clinical course and adjusting anticholinesterase therapy accordingly.

Thirty-three patients with type 2 diabetes mellitus (16 men, 17 women) were divided into 3 groups based on urinary excretion of albumin (U-Alb)--group A: U-Alb < 30 mg/d; group B: 30 mg/d < or = U-Alb < or = 300 mg/d; and group C: 300 mg/d < U-Alb. Serum creatinine levels were lower than 2.0 mg/dL in all the subjects. There was no difference in age, sex, therapy, body weight, body mass index (BMI), lean body mass (LBM), or hemoglobin A(1c) (HbA(1c)) levels among the 3 groups. Resting metabolic rate (RMR) (kJ/h/m(2)) and adjusted RMR for lean body mass (kJ/h/m(2)) were significantly increased in group C compared with groups A and B. Hb concentrations, serum albumin levels, and creatinine clearance were much lower in group C than in groups A and B (P < .001). There were no difference in serum urea nitrogen, total cholesterol, cholinesterase and free thyroxine, or plasma insulin-like growth factor I (IGF-I) levels among the 3 groups. Linear regression analysis revealed an inverse correlation between RMR and serum albumin levels, correlation between RMR and U-Alb, and inverse correlation between RMR and Hb concentrations, respectively, in these patients. In conclusion, RMR in diabetic patients correlated directly with U-Alb and inversely with serum albumin and Hb concentration. These findings suggest that RMR is related with urinary albumin loss and anemia in patients with type 2 diabetes mellitus accompanied by diabetic nephropathy.

Although organochlorine (OC) pesticides were replaced with organophosphates (OPs) in the early 1970s, they continue to persist in orchard environments today. Extensive research has been conducted to determine the effects of currently used OPs on cholinesterase (ChE) activity; however, although OCs continue to be prevalent in areas of previous use, few studies have looked at the toxicity of a combination of residual OC compounds with currently used OP pesticides. The focus of our study was to determine the effects of azinphos-methyl (a common OP used in apple orchards today) on ChE activity and general health in zebra finches (Taeniopygia guttata) previously exposed to p,p'-DDE (a commonly detected metabolite of DDT). The main results of our study were as follows: (1) azinphos-methyl alone caused a dose-dependent inhibition of plasma and brain ChE activity; (2) p,p'-DDE in combination with azinphos-methyl did not change azinphos-methyl inhibition of ChE activity; and (3) there were suggestions of immunostimulation in birds dosed 1 year previously to p,p'-DDE and of anemia when p,p'-DDE was combined with azinphos-methyl; however, there was no dose-response for these parameters in birds subsequently dosed with p,p'-DDE.

We describe a case of pure red cell aplasia caused by a B19 parvovirus infection in a female myasthenic patient treated with plasma exchange, corticosteroids, and cholinesterase inhibitors. Two weeks after albumin infusion, she developed anemia with an absence of reticulocytes. A bone marrow aspirate was performed, showing a markedly hypoplastic erythroid series with numerous giant pronormoblasts. Anemia with severe reticulocytopenia and morphology of bone marrow suggested a diagnosis of pure erythroblastopenia due to parvovirus B19 infection, which was confirmed by positive immunoglobulin (Ig)M] and IgG anti-B19 virus. The patient successfully responded to IVIG treatment with a complete remission. In this case, we could not confirm whether an albumin-derived infection combined with a concomitant immunocompromised condition due to myasthenia and immunosuppressive treatment was responsible for the disease. Although human B19 DNA content does not reflect infectivity, it is not possible to exclude that blood derivates, such as albumin, clot factors, and immune globulin may be infectious. Actually, blood component B19 infection is still an unresolved problem. Many strategies such as new methods for viral inactivation and discarding positive B19 units may help to increase blood product safety.
