OBJECTIVETo analyze serum levels of non-esterified fatty acids (NEFA) and albumin (ALB) in children with nephrotic syndrome (NS) and investigate the clinical significance of altered serum NEFA to ALB ratio in children with NS in acute and remission phases.
METHODSSerum levels of NEFA and ALB were measured in 55 NS children in acute phase, in 33 NS children in remission and in 122 healthy control children, and the ratio of NEFA to ALB was calculated. The other lipid/lipoprotein and renal function parameters were also analyzed in these children.
RESULTSCompared with the healthy control children, children with NS had a significantly decreased serum ALB level (t=11.152, P<0.001) and a significantly increased NEFA to ALB ratio (t=4.991, P<0.001). Compared with NS children in remission, those in acute phase showed a significantly decreased ALB (Z=7.822, P<0.001) and an increased NEFA to ALB ratio (t=4.991, P<0.001). In all the NS children, NEFA to ALB ratio was positively correlated with the levels of TC (r=0.564, P<0.001), TG (r=0.444, P<0.001), LDL-C (r=0.625, P<0.001), urea (r=0.437, P<0.001), creatinine (r=0.278, P=0.013), and uric acid (r=0.397, P<0.001), while negatively correlated with the level of total protein (r=-0.461, P<0.001). Multiple linear regression analyses showed that NEFA to ALB ratio was independently associated with serum urea levels (β=0.703, P=0.001; adjusted R=0.494) after adjustment of other related factors.
CONCLUSIONSerum NEFA to ALB ratio is significantly increased in NS children in close association with impaired kidney function, and may function as a novel parameter for assessing the development of NS.

Albumin is the most abundant protein in human serum. A dye-binding method is commonly used in clinical laboratories for its estimation using different types of dyes. However, all these dye methods were interfered by a variety of compounds. Here we present a method for the detection of albumin in human serum and other biological fluids. The principle is based on the fact that lactate dehydrogenase isoenzyme-5 (LDH-5) binds specifically to Dextran-Blue (DB). Albumin inhibits the binding of LDH-5 with DB. Absence of LDH activity in DB fraction after gel filtration indicates the presence of albumin in sample and vice versa.

Malnutrition is one of the most important factors for the development of nosocomial infection (NI). We performed a study of the correlation between abnormal nutritional factors and NI risk by investigating the patients who stayed longer than 3 days in the intensive care unit (ICU) of our university hospital. The patients were classified into three groups based on serum albumin levels and total lymphocyte counts (TLC). The criteria of Group I (well nourished group) were serum albumin level of 3.5 g/dl or higher and TLC of 1, 400/mm3 or higher. The criteria of Group III (severely malnourished group) were serum albumin of less than 2.8 g/dl and TLC of less than 1, 000/mm3. The other patients were classified as Group II (moderately malnourished group). The occurrences of NI were monitored during the study period and the APACHE III Score was calculated. The probability of first NI infection in Group III was 2.4 times higher than that in Groups I and II. The mortality rate of 20.5% was more significantly correlated with APACHE III Score than nutritional status. Nineteen (53%) of the total 36 NI patients were infected within 10 days after ICU admission and they all belonged to Group III. When we compared the gap period between infections, the time to first infection was significant.

The aim of this cross-over study was to investigate whether albumin infusion before furosemide administration could potentiate the diuretic action of furosemide. Seven patients with nephrotic syndrome were given the following infusions in random order on two separate days: 1) a sham solution followed by 160 mg of furosemide, 2) 100 ml of 20% human albumin followed by 160 mg of furosemide. Urine and serum furosemide concentrations were measured by high-performance liquid chromatography. The increment of urine volume was greater in albumin preinfusion than in furosemide alone. However, the increments of sodium and chloride excretions between furosemide alone and albumin preinfusion were not different. No significant differences in the pharmacokinetic parameters between the two treatments were observed: area under the concentration-time curve (AUC: 12.7+/-2.2 vs 15.1+/-4.4 g/ml hr), total plasma clearance (253+/-41 vs 256+/-54 ml/min), volume of distribution (341+/-34 vs 494+/-153 ml/kg), elimination half life (4.0+/-1.1 vs 4.6+/-0.8 hr), and urine furosemide excretion of the administered amount (16.5+/-7.3 vs 7.5+/-1.6%). In conclusion, these data show that albumin preinfusion potentiated diuresis, but not natriuresis, of furosemide without any change in the pharmacokinetics of the agent in patients with nephrotic syndrome.

OBJECTIVES:
To analyze the clinical characteristics in patients of coronavirus disease 2019 (COVID-19) complicated with liver injury, to explore the relationship between COVID-19 clinical classification and liver injury, and to elucidate whether COVID-19 complicated with hepatitis B virus can aggravate liver injury.
METHODS:
The abnormal liver function in 110 patients in the First Hospital of Changsha, who were confirmed COVID-19 and admitted to the designated hospital from January 17, 2020 to February 20, 2020, wereretrospectively analyzed. The detection indexes included serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBIL).
RESULTS:
A total of 49.1% of the COVID-19 patients had liver injury. There were significant difference in the ALT, AST, ALB (all <0.05), but there was no significant difference in the TBIL (>0.05) between the severe (critical) patients and the general (light) patients. There was also no significant difference in the liver function injury between the HBsAg-positive COVID-19 patients and HBsAg-negative COVID-19 patients (>0.05). Acute liver injury was not found to be a direct cause of death in the patients.
CONCLUSIONS
In the COVID-19 patients, the incidence of liver injury is high with the increase of ALT and AST and the decrease of ALB. Severe and critical patients have obvious liver injury, and those patients complicated with hepatitis B virus infection don't show aggravated liver injury.

BACKGROUND/AIMS: It is well-known that patients with chronic liver disease commonly have nutritional deficiency. In the present study, we investigated the differences in malnutrition risk between patients with liver cirrhosis and viral hepatitis carrier. METHODS: Patients with chronic liver disease who have been hospitalized at Konyang University Hospital from May 2012 to April 2013 were analyzed retrospectively. The malnutrition risk was divided into three categories (low, intermediate, and high) according to Konyang University Hospital Malnutrition Screening, which include BMI, serum albumin, total lymphocyte count (TLC), hemoglobin, weight change, appetite, and dysphagia, within 24 hours of hospitalization. RESULTS: Among a total of 460 patients, 313 had liver cirrhosis (LC), and 147 were viral hepatitis carriers. Age (p<0.001), serum albumin level (p<0.001), TLC (p=0.011), hemoglobin (p<0.001) and serum cholesterol level (p=0.005) were significant different between the two groups. However, there were no difference in height, weight, and BMI. The malnutrition risk of the patients with viral hepatitis carrier was significantly lower than that of the patients with LC (p<0.001). In addition, among 313 patients with LC, malnutrition risk of the patients with Child-Pugh class A (n=150) was significantly lower than that of the patients with class B (n=90) or C (n=73) (p<0.001). CONCLUSIONS: Viral hepatitis carrier group had significantly lower malnutrition risk than LC group. The risk of malnutrition in Child-Pugh class A group was significantly lower than that in class B or C group.

BACKGROUND/AIMS: Liver biopsy is a standard method for diagnosis of liver cirrhosis in patients with chronic hepatitis. Because liver biopsy is an invasive method, non-invasive methods have been used for diagnosis of compensated liver cirrhosis in patients with chronic hepatitis. The current study was designed to evaluate the usefulness of ultrasonography and routine blood tests for diagnosis of compensated liver cirrhosis in patients with chronic viral hepatitis. METHODS: Two hundred three patients with chronic viral hepatitis who underwent liver biopsy were included in this study and ultrasonography and routine blood tests were analyzed retrospectively. Ultrasonographic findings, including surface nodularity, parenchyma echogenecity, and spleen size, were evaluated. The diagnostic accuracy of ultrasonography and routine blood tests were examined. RESULTS: Discriminant analysis with forward stepwise selection of variables showed that liver surface nodularity, platelet count, and albumin level were independently associated with compensated liver cirrhosis (p<0.05). Cross-tabulation revealed that the following 4 variables had >95% specificity: platelet count <100,000 /uL; albumin level <3.5 g/dL; INR >1.3; and surface nodularity. If at least one of the four variables exists in a patient with chronic viral hepatitis, we can predict liver cirrhosis with 90% specificity and 61% sensitivity. CONCLUSIONS: These results suggest that four variables (platelet count <100,000 /uL, albumin level <3.5 g/dL, INR >1.3, and surface nodularity) can be used for identification of liver cirrhosis in patients with chronic viral hepatitis with high specificity.

In order to investigate cytokine productions in patients undergoing continuous ambulatory peritoneal dialysis (CAPD), we studied the production of interleukin (IL)-1 beta, -6 and interferon (IFN)-gamma by cultured peripheral blood mononuclear cells (PBMC) in peritonitis-free CAPD patients. The correlation of cytokine production with plasma parathyroid hormone (PTH) and albumin levels was also evaluated. While the release of IL-1 beta was not markedly different from controls release of IL-6 from 24-hour cultured PBMCs was significantly greater than that of controls, (Mean +/- S.D., IL-6: 2186.8 +/- 1217.9 pg/ml, vs 1516.3 +/- 767.9, P <0.05). The addition of lipopolysaccharide (LPS, 10 micrograms/ml, significantly stimulated IL-1 beta and -6 production of PBMCs in CAPD patients and controls, compared to an unstimulated condition. The LPS-induced IL-1 beta production was also not markedly different from controls, whereas LPS-induced IL-6 production was significantly higher than controls (IL-6: 13,220.7 +/- 7177.4 vs 7411.4 +/- 1236.9, P <0.05). However, the percentage increases of IL-6 production stimulated with LPS in CAPD patients were not significantly different from controls (p > 0.05). No difference of baseline IFN-gamma was detected between CAPD patients controls, but phytohemagglutinin (PHA, 10 micrograms/ml)-stimulated IFN-gamma release was significantly higher in CAPD patients than controls (2425.9 +/- 1565.0 pg/ml vs 1364.0 +/- 755.1, P <0.05). There was no significant correlation between PTH and, IL-1 beta, serum albumin level and LPS-stimulated IL-6 production (r = 0.54, P <0.05). In conclusion, CAPD seems to partly induce activation of PBMCs with an enhanced release of IL-6 and IFN-gamma, and CAPD patients with higher serum albumin levels tend to show higher IL-6 production in immune response.

OBJECTIVETo identify and explore the prognostic risk factors of the hemophagocytic syndrome (HPS).
METHODSA retrospective study was conducted on 50 childhood patients with HPS who were admitted to our hospital between 2007 and 2011. All their medical records were reviewed and analyzed. For each patient, demographic, laboratory data and outcome information were collected. The patients were divided into deceased or survived groups based on the follow-up results. Comparative analysis of the data was done by using independent-samples test and logistic multiple and univariate regression.
RESULTSAmong the 50 HPS patients, 30 were male and 20 female, age ranged from 3 months to 10 years. Reduction of serum albumin, cholinesterase and natural killer (NK) cells was found in the forty-six patients. The laboratory features showed an elevation of serum ferritin with hypofibrinogenemia and hypertriglyceridemia in most of the patients. Forty of patients had hemophagocyte in bone marrow at diagnosis of HPS. The positive serum EBV-IgM was found in thirty-five patients.During the observation period, 25 of 37 patients (67.6%) died, while 13 of whom died within a month after hospitalization. The deceased patients were more likely to have lower albumin, cholinesterase, NK cells level and more prolonged active partial thromboplastin time than the survived patients (P < 0.05). Multivariate logistic regression analysis revealed that duration of illness > 1 month, albumin level < 25 g/L, cholinesterase level < 2000 U/L, NK cell level 0-3% and positive EBV-IgM were related with the prognosis significantly (P < 0.05 for all comparisons).
CONCLUSIONThis study revealed that duration of illness > 1 month, decreases in albumin, NK cell and cholinesterase, and positive EBV-IgM were the risk factors related to mortality in children.
