Xiang-sha Warming (XSW) and Shashen Nourishing Decoction (SSN) were used in treating Yang Deficiency Syndrome (YaDS) and Yin Deficiency Syndrome (YiDS) of chronic atrophic gastritis (CAG) respectively. 121 cases with Spleen YaDS, and 29 cases with Spleen YiDS were selected. 26 and 30 specimens were taken from gastric mucosa for observation under the SEM and TEM, including 12 and 12 YaDS cases, 14 and 12 Spleen Qi Deficiency cases respectively, 2 cases of YiDS were also observed with TEM. The specimens were taken from the same site of the gastric mucosa directly under the gastroscope pre- and post-treatment. 43 patients (35.6%) with spleen YaDS and 5 cases (17.2%) in Spleen YiDS showed marked effect after 3-month treatment. It showed that the effect in Spleen YaDS was better than YiDS. The XSW was superior than that of SSN. The effects were related to the syndromes and the degrees of pathologic change. This showed that the recipe could somewhat reverse and restore the abnormal glands of gastric mucosa.

Total plasma fatty acids were measured in 101 cirrhotic inpatients (64 men, 37 women, aged 64.3 +/- 1.2 (SEM) yr; range, 34-80) who were subsequently followed for survival for a mean of 14.8 +/- 1.0 months. Data on plasma fatty acids have been published elsewhere. Individual values of these variables were categorized in a binary fashion using the 5th or the 95th percentiles of a group of 44 well-nourished healthy controls (24 men, 20 women, aged 51.3 +/- 2.1 yr; range, 32-76) as the cutoff limit. Forty-nine patients died during follow-up (2-yr cumulative probability of survival, 52%). Deficiency of palmitate, dihomo-tau-linolenate, and arachidonate (values below the 5th percentile) were univariately associated with death (long-rank test). However, after a multivariate analysis (Cox's proportional hazards regression), only the existence of plasma arachidonate deficiency was included in the final model (beta, 0.62; relative risk, 1.86; 95% CI, 1.06-3.25; p < 0.05). We conclude that arachidonic acid deficiency significantly increases the mortality risk in patients with advanced liver cirrhosis.

Malnutrition in hemodialysis patients is associated with increased morbidity and mortality. The use of intradialytic parenteral nutrition (IDPN) to improve nutritional parameters has been shown to be of limited benefit in most studies. We studied the use of recombinant human growth hormone (rHuGH) in potentiating the effects of IDPN in seven hemodialysis patients dialyzed with a Kt/V of 1.03 +/- 0.11 (mean +/- SEM), but with evidence of malnutrition: albumin, 3.2 +/- 0.18 g/dL; transferrin, 215 +/- 30 mg/dL; insulin-like growth factor-1 (IGF-1), 115 +/- 19 ng/mL, protein catabolic rate (PCR), 0.70 +/- 0.05 g/kg/d; and weight, 12.3% +/- 4.0% below ideal body weight. During 6 weeks of IDPN, resulting in an additional 18 +/- 4 kcal and 0.69 +/- 0.03 g of protein/kg body weight per dialysis session, albumin concentration increased to 3.5 +/- 0.14 g/dL (compared with baseline, P = NS), transferrin increased to 279 +/- 36 mg/dL (P < 0.002), IGF-1 increased to 152 +/- 32 ng/mL (P = NS), and PCR increased to 0.81 +/- 0.04 g/kg/d (P = NS). During the next 6 weeks, IDPN administration was continued and rHuGH, at a dose of 5 mg subcutaneously during each dialysis, was added to the regimen. This resulted in an increase in albumin concentration to 3.8 +/- 0.08 g/dL (P < or = 0.04 compared with end of IDPN phase), an increase in transferrin to 298 +/- 41 mg/dL (P = NS compared with end of IDPN phase), and an increase in IGF-1 to 212 +/- 45 ng/mL (P = 0.05 compared with end of IDPN phase).(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between insulin-like growth factor-I (IGF-I), body weight, and serum albumin was studied in 17 patients on continuous ambulatory peritoneal dialysis (CAPD) and 17 patients on hemodialysis. Patients were matched for gender, age (33-83 years), body mass index (16.7-36.1 kg/m2), hematocrit, concentrations of serum growth hormone, and duration of dialysis (1-210 months). Serum IGF-I concentration was measured by radioimmunoassay (Incstar) and albumin by a standard laboratory technique. CAPD patients had significantly lower serum albumin concentrations than hemodialysis patients, whereas IGF-I levels in the two groups were similar and did not differ from those in 18 normal subjects. We did not find significant positive correlations between IGF-I and serum albumin levels in CAPD or in hemodialysis patients. On the other hand, IGF-I showed a strong positive correlation with body weight (for the CAPD group r = 0.523; for both groups together r = 0.493). Both groups (CAPD and hemodialysis) and CAPD patients who weighted less than 60 kg (44%) had significantly lower serum IGF-I levels (113.5 +/- 10.2 and 108.8 +/- 15.7 micrograms/l +/- SEM, respectively) than patients who weighed 60-80 kg (38.3%; 181.2 +/- 20.9 and 196.6 +/- 27.2 micrograms/L +/- SEM, respectively) or above 80 kg (17.6%; 205.2 +/- 37.7 and 229.5 +/- 43.5; micrograms/L +/- SEM, respectively). It therefore appears that a low serum IGF-I level is a better indicator of malnutrition in CAPD and hemodialysis patients than low serum albumin.

Lean body mass (LBM), which is fat free body mass, can be used as an index of nutritional status. We evaluated three techniques for LBM estimation, including dual energy x-ray absorptiometry (DEXA), creatinine kinetics (CrKin), and bioimpedance (BI) in 10 patients on continuous ambulatory peritoneal dialysis (CAPD). Two different formulae were applied for BI LBM estimation, Segal (S) and Deurenberg (D). Mean values (+/- SEM) of LBM estimated were 48.2 +/- 3.6, 46.12 +/- 2.87, 43.32 +/- 3.87, and 41.27 +/- 4.26 by DEXA, BI-S, BI-D, and CrKin, respectively. LBM by CrKin was significantly lower than that by DEXA and BI-S values. There was no statistically significant difference between DEXA and BI-S values. Statistically significant correlations were found between LBM values by all methods. Particularly strong correlations were found between DEXA versus BI-S (r = 0.976) and BI-S versus BI-D (r = 0.98). Because clinical assessment of hydration status is inaccurate, and both BI and DEXA measure excess extracellular water in LBM, falling muscle mass may be missed by these techniques. The CrKin technique for estimating LBM at normal body fluid volumes (dry weight) may be a better index of nutritional status in patients on CAPD because this may truly reflect the dry LBM and changes in muscle mass. Both DEXA and BI include excess body water in LBM and may mask malnutrition in the presence of subclinical or clinical overhydration, which is common in patients on peritoneal dialysis.

We compressed 16 test-pattern classes of albumin (ALB), cholesterol (CHOL), and total protein (TPR) in 545 chemistry profiles to 4 classes by converting decision values to a number code to separate malnourished (1 or 2) from nonmalnourished (NM) (0) patients, using as cutoff values for nonmalnourished (0), mild (1), and moderate (2): ALB 35, 27 g/L; TPR 63, 53 g/L; CHOL 3.9, 2.8 mmol/L; and BUN 9.3, 3.6 mmol/L. The BUN was found to have too low an S-value to make a contribution to the compressed classification. The cutoff values for classifying the data were assigned prior to statistical analysis, after examining information in the structured data. The data was obtained by a natural experiment in which the test profiles routinely done by the laboratory were randomly extracted. The analysis identifies the values for the variables used that best classify the data and are not dependent on distributional assumptions. The data were converted to 0, 1, or 2 as outcomes, to create a ternary truth table (each row is nnnn, the n value is 0 to 2). This allows for 3(4) (81) possible patterns, without the inclusion of prealbumin (PAB). The emerging system has much fewer patterns in the information-rich truth table formed (a purposeful, far from random, event). We added PAB, coded, and examined the data for 129 patients. The classes are a compressed truth table of n-coded patients with outcomes of 0, 1, or 2 with protein-energy malnutrition (PEM) increasing from an all-0 to all-2 pattern. Pattern class (F = 154), PAB (F = 35), ALB (F = 56), and CHOL (F = 18) were different across PEM class and predicted PEM class (R2 = 0.7864, F = 119, p < E-5). Kruskal-Wallis analysis of class by ranks was significant for pattern class (1E-18), PAB (6.1E-15), ALB (1E-16), CHOL (9E-10), and TPR (5.3E-13). The medians and standard error (SEM) for PAB, ALB, and CHOL of all four PABCLASSES (NM, mild, moderate, severe) are: PAB = 209, 8.7; 159, 9.3; 137, 10.4; 72, 11.1 mg/L, ALB = 36, 0.7; 30.5, 0.8; 25.0, 0.8; 24.5, 0.8 g/L; CHOL = 4.43, 0.17; 4.04, 0.20; 3.11, 0.21; 2.54, 0.22 mmol/L. PAB and CHOL values show the effect of nutrition support on PAB and CHOL in PEM. Moderately malnourished patients receiving nutrition support have PAB values in the normal range at 137 mg/L and at 159 mg/L when the ALB is at 25 g/L or at 30.5 g/L.

Unidentified protein-energy malnutrition (PEM) is associated with comorbidities and increased hospital length of stay. We developed a model for identifying severe metabolic stress and likelihood of malnutrition using test patterns of albumin (ALB), cholesterol (CHOL), and total protein (TP) in 545 chemistry profiles. Pattern classes were derived by converting decision values to a number code using cutoff values for nonmalnourished (0), moderate (1), and severe (2) of: ALB 35, 27 g/L; TP 63, 53 g/L; and CHOL 3.9, 2.8 mumol/L. Patterns defined by combinations of normal and abnormal laboratory results had decreased the likelihood of PEM from an all-2 to all-0 pattern. They were compressed to four final classes. ALB (F = 170), CHOL (F = 21), and TP (F = 5.6) predicted PEM class (r2 = 0.806, F = 214; P < E-6), but pattern class was the best predictor (r2 = 0.900, F = 1200, P < E-10). Kruskal-Wallis analysis of class by ranks was significant for pattern class (E-18), ALB (E-18), CHOL (E-14), and TP (2E-16). The means and SEM for tests in three PEM classes (mild, moderate, severe) were: ALB-35.7, 0.8; 30.9, 0.5; 24.2, 0.5 g/L; CHOL-3.93, 0.26; 3.98, 0.16; 3.03, 0.18 mumol/L, and TP-68.8, 1.7; 60.0, 1.0; 50.6, 1.1 g/L. We classified patients at risk of malnutrition using truth table comprehension. The pattern classes formed by the tests are a better classifier than the tests themselves.

Neonatal brain development in the rat is adversely affected by malnutrition. Alterations in tissue binding of IGF-I in the malnourished brain were tested in rat pups from mothers who were fed a 20% protein diet (C) or a 4% protein diet (M) starting from day 21 of gestation and continued throughout suckling. IGF-I binding in both cortex and cerebellum decreased progressively in C and M groups from day 6 to day 13. At day 9, 11, and 13, the binding was significantly greater (p < 0.02) in M compared to C groups. To investigate whether these changes might be related to the alteration in receptor activity, membranes were incubated with 125I-IGF in the presence of excess insulin with or without unlabeled IGF-I. In the absence of insulin, specific IGF-I binding in the M group was increased by 41.8 +/- 13.8% (mean +/- SEM p < 0.05) relative to C group. Insulin produced a consistent but incomplete inhibition of binding in both C and M, of 75% and 67% respectively. In addition, the specific IGF-I binding in the presence of insulin was increased in M group by 70.2 +/- 9.4% relative to C, p < 0.05. To characterize the nature of this binding, cerebral cortical membranes, from both groups, incubated with 125I-IGF-I were cross-linked, and electrophoresed on 6% and 10% SDS-PAGE gels under reducing conditions. Autoradiography of the 6% gel showed two specific bands at 115 kD and 240 kD, consistent with monomeric and dimeric forms of the IGF-I receptor, which were inhibited by excess insulin. In contrast, a 10% gel showed an additional band at 35 kD (IGF-binding protein) that was not inhibited by insulin. In both gels, membrane preparations from the M group showed a heightened intensity of the bands relative to C. The increase in binding protein relative to the receptor suggests a disequilibrium that may limit the availability of exogenous IGF-I to the tissues.

Previous studies have demonstrated an association between low weight at birth and risk of later development of non-insulin-dependent diabetes mellitus (NIDDM). It is not known whether this association is due to an impact of intrauterine malnutrition per se, or whether it is due to a coincidence between the putative "NIDDM susceptibility genotype" and a genetically determined low weight at birth. It is also unclear whether differences in gestational age, maternal height, birth order and/or sex could explain the association. Twins are born of the same mother and have similar gestational ages. Furthermore, monozygotic (MZ) twins have identical genotypes. Original midwife birth weight record determinations were traced in MZ and dizygotic (DZ) twins discordant for NIDDM. Birth weights were lower in the NIDDM twins (n = 2 x 14) compared with both their identical (MZ; n = 14) and non-identical (DZ; n = 14) non-diabetic co-twins, respectively (MZ: mean +/- SEM 2634 +/- 135 vs 2829 +/- 131 g, p < 0.02; DZ: 2509 +/- 135 vs 2854 +/- 168 g, p < 0.02). Using a similar approach in 39 MZ and DZ twin pairs discordant for impaired glucose tolerance (IGT), no significantly lower birth weights were detected in the IGT twins compared with their normal glucose tolerant co-twins. However, when a larger group of twins with different glucose tolerance were considered, birth weights were lower in the twins with abnormal glucose tolerance (NIDDM + IGT; n = 106; 2622 +/- 45 g) and IGT (n = 62: 2613 +/- 55 g) compared with twins with normal glucose tolerance (n = 112: 2800 +/- 51 g; p = 0.01 and p = 0.03, respectively). Furthermore, the twins with the lowest birth weights among the two co-twins had the highest plasma glucose concentrations 120 min after the 75-g oral glucose load (n = 86 pairs: 9.6 +/- 0.6 vs 8.0 +/- 0.4 mmol/l, p = 0.03). In conclusion, the association between low birth weight and NIDDM in twins is at least partly independent of genotype and may be due to intrauterine malnutrition. IGT was also associated with low birth weight in twins. However, the possibility cannot be excluded that the association between low birth weight and IGT could be due to a coincidence with a certain genotype causing both low birth weight and IGT in some subjects.

Malnutrition in patients with chronic obstructive pulmonary disease (COPD) is classically ascribed to an increased resting energy expenditure (REE) secondary to high cost of breathing. However, malnutrition correlates only weakly with the severity of respiratory dysfunction, which suggests other mechanisms. The aim of the present study was to determine the possible role of diet-induced thermogenesis (DIT). Therefore, we evaluated the relationship between DIT and nutritional status, in particular fat-free mass (FFM) estimated by bioelectrical impedance analysis in 26 patients with stable COPD (mean FEV1 +/- SEM = 36.5 +/- 3.8% of predicted). Ten patients were undernourished (weight < 90% of ideal body weight [IBW] and/or FFM < 69% of IBW), and 16 were normally nourished. Diet-induced thermogenesis was determined by comparing postprandial energy expenditure and REE, the latter being measured after an overnight fast and the former over 4 h after a mixed test meal of 0.4 times REE load. No statistical difference in DIT was found between undernourished and eutrophic patients. There was no relationship between DIT and nutritional or functional parameters, notably FFM. These results suggest that malnutrition is not a consequence of an increased DIT.
