Abstract
The aim of this comparative study was to investigate the clinical usefulness of the measurement of Toxoplasma gondii IgG avidity in the postnatal diagnosis of congenital toxoplasmosis. IgG avidity values in serum samples from infants with congenital infection were compared with those in samples from uninfected infants, all born to mothers with toxoplasmosis acquired during gestation. This analysis revealed that IgG avidity values soon after birth reflected maternal values in the large majority of the samples. Low or borderline IgG avidity values were systematically found in the cohort of congenitally infected subjects. After birth, IgG avidity values slowly increased over time for up to 2 years in congenitally infected subjects. On the contrary, IgG avidity values in the uninfected infants remained stable over time. The presence of low IgG avidity in a newborn can be considered a marker of maternal seroconversion in the second or third trimester of gestation and, as a consequence, an indicator of risk for congenital toxoplasmosis. An IgG avidity assay can be easily carried out with antibodies eluted from dried blood spots (Guthrie cards), providing an opportunity to retrospectively evaluate the risk of congenital infection in special clinical circumstances, for example when suspicion of congenital infection arises during late infancy.

Abstract
BACKGROUND Senna laxatives are used worldwide. However, their misuse can lead to chronic mucosal inflammation with the accumulation of pigment-laden leukocytes and may cause colon cells to undergo apoptosis. This study explores the mechanisms by which rhein, an active component of senna, acts on a human intestinal cell line to induce ion secretion, apoptosis, and indirect chemotaxis of polymorphonuclear leukocytes. METHODS Human colonic adenocarcinoma (CaCo-2) monolayer cells, in the presence or in the absence of rhein, were used to monitor the production of reactive nitrogen species using the Griess reaction. Modified Ussing chambers were used to study electrolyte secretion. The capacity to recruit human polymorphonuclear leukocytes was evaluated using masked well chemotaxis chambers. Rhein-induced apoptosis was investigated by counting apoptotic nuclei stained with Hoechst 33258 dye. RESULTS Rhein caused a dose-dependent increase in short-circuit current that was abolished in chloride-free bathing buffer or by preincubating with 100 micromol/L NG-nitro-L-arginine (L-NAME) methyl ester. The concentration that maximally stimulated intestinal secretion, 50 micromol/L rhein, induced nitrate production. Supernatants obtained from CaCo-2 cultures after incubation with 50 micromol/L rhein stimulated a time-dependent polymorphonuclear leukocytes chemotaxis that was significantly decreased with 100 micromol/L L-NAME, whereas rhein per se was not active. Neutralizing antibodies anti-interleukin-8 (IL-8) and anti-ENA78 also inhibited chemotaxis. Overnight rhein incubation produced an increased number of apoptotic cells in the culture supernatant that was significantly decreased by preincubation with 100 micromol/L L-NAME. Light-degraded rhein had no effects on CaCo-2 monolayers. CONCLUSIONS The integrity of rhein is crucial to generating nitric oxide, which mediates, with different time courses, ion secretion, chemotaxis, and apoptosis of human-derived cells.

Abstract
In this study, we have investigated the effect of hydrophobic and hydrophilic unconjugated bile acids (UBAs)-ursodeoxycholic acid (UDCA), chenodeoxycholic acid (CDCA), lithocholic acid, and colic acid-on chemotaxis in adult and neonatal human polymorphonuclear leukocytes (PMNs). The trypan blue exclusion dye test was preliminarily performed to determine the toxicity of the studied UBAs on PMNs. N-formyl-methionyl-leucyl-phenylalanine (100 nM) was used as a chemoattractant. Chemotaxis (1 x 10(6)cells/mL) was analyzed in the presence or absence of UBAs (10 microM) by blind well chambers. The antioxidants vitamin E and vitamin C were tested for their ability to reduce the inhibitory effect of UBAs. We found that only CDCA was able to induce damage in PMNs in the range of 1-40 microM. Both CDCA and UDCA were able to inhibit chemotaxis in PMNs, whereas lithocholic acid and colic acid were ineffective. The inhibitory effect was reversible inasmuch as PMNs incubated with either CDCA or UDCA and subsequently washed showed normal chemotaxis. Concomitant incubation of PMNs with UBAs and vitamins C or E reversed the inhibition. We did not find substantial differences between PMNs from adults or newborns. In conclusion, CDCA and UDCA are able to reduce, in a specific and reversible fashion, both adult and newborn neutrophil chemotaxis. As concomitant incubation of UBAs and electron scavengers restores PMN chemotaxis to control values, we conclude that free radicals may be involved in the mechanism of inhibition. We speculate that this defect may contribute to the impaired host response described in cholestatic patient.

Abstract
Intestinal lymphangiectasia is characterized by obstruction of lymph drainage from the small intestine and lacteal dilation that distorts the villus architecture. Lymphatic vessel obstruction and elevated intestinal lymphatic pressure in turn cause lymphatic leakage into the intestinal lumen, thus resulting in malabsorption and protein-losing enteropathy. Intestinal lymphangiectasia can be congenital or secondary to a disease that blocks intestinal lymph drainage. We describe the first case of intestinal lymphangiectasia in a premature infant. The infant presented with peripheral edema and low serum albumin; high fecal concentration of alpha(1)-antitrypsin documented intestinal protein loss. Endoscopy showed white opaque spots on the duodenal mucosa, which indicates dilated lacteal vessels. Histology confirmed dilated lacteals and also showed villus blunting. A formula containing a high concentration of medium chain triglycerides resulted in a rapid clinical improvement and normalization of biochemical variables. These features should alert neonatologists to the possibility of intestinal lymphangiectasia in newborns with hypoalbuminemia and peripheral edema. The intestinal tract should be examined for enteric protein losses if other causes (ie, malnutrition and protein loss from other sites) are excluded. The diagnosis rests on jejunal biopsy demonstrating dilated lymphatic lacteal vessels.

Abstract
Gestational maturation of gastrointestinal motility is a key factor in readiness of the preterm neonates for enteral nutrition. Since gastric motility mainly depends on the electrical activity of the smooth muscle cells, it was of interest to investigate the developmental aspects of electrical activity of the stomach. The latter was recorded weekly through cutaneous electrogastrography in 27 preterm infants (aged 29-34 weeks of gestation). Recordings were done for 1 hr before and 1 hr after meal. The electrogastrographic variables measured were: percentage of normal gastric rhythm, ie, 2-4 cpm; percentage of tachygastria (>4 cpm); the fed-to-fasting ratio of the dominant electrogastrographic power; and the instability coefficient of the dominant frequency. Data were compared with those measured in 10 full-term infants. Peaks of normal electrical activity (2-4 cpm) were present in most of the recordings at all the gestational ages; however, percentages of both normal electrical rhythm and tachygastria in preterm infants were similar to those measured in full-term infants (mean +/- SD) (normal rhythm; fasting: 70.2 +/- 3.8, fed: 72.2 +/- 5.0; tachygastria: fasting: 24.6 +/- 4.0, fed: 19.1 +/- 3.5) by 35 weeks of gestation (normal rhythm; fasting: 67.5 +/- 2.0, fed: 69.6 +/- 4.4; tachygastria: fasting: 27.1 +/- 4.0, fed: 25.6 +/- 4.1). The coefficient of instability of the dominant frequency in preterm infants was also similar to the value measured in full-term infants by 35 weeks of gestation, whereas the EGG power showed a significant increase in the postprandial state at all the gestational ages. We conclude that a maturation pattern of the electrical activity of the stomach can be detected by means of a noninvasive tool such as cutaneous electrogastrography: a normal electrical rhythm can be detected at very early gestational ages; however, this activity becomes dominant at around the 35 weeks of gestational age. In preterm infants developmental changes of gastric electrical activity are a function of advancing postnatal age.

Abstract
Modulation of neutrophil response to naturally occurring stimuli is important to avoid host tissue injure. Both soluble and particulate stimuli may induce superoxide anion generation in human polymorphonuclear leukocytes. Recently wortannin has been shown to inhibit the N-formyl-methionyl-leucyl-phenylalanine (fMLP) induced activation of respiratory burst via phosphatidylinositol 3-kinase. However no data are available about the effect of the inhibitor on the respiratory burst induced by a particulate stimulus. In this paper we studied the effect of wortmannin on E. coli induced respiratory burst and phagocytosis by flow cytometry, which allows the quantitation of both H2O2 production and ingested bacteria in whole blood samples without the need of purification and concomitant manipulation of the cells. The effects of worthmannin on fMLP-induced chemotaxis was also examined by the under agarose method. Neither the E. coli nor the fMLP-induced responses were blocked by wortmannin, suggesting that PI 3-kinase activity is not required to activate these neutrophil functions. Since it is known that the respiratory burst elicited by fMLP is blocked by wortmannin, our results suggest that the generation of oxygen radicals is controlled via different signal transduction pathways, depending on the agonist used.

Abstract
D-myo-Inositol 1,4,5-triphosphate (IP3) is a key second messenger in many cells, including macrophages, T and B cells, and neutrophils, in which it regulates free intracellular calcium ion levels. In human polymorphonuclear leukocytes the rise of intracellular [Ca2+] is the signal that activates a number of functions such as adherence, aggregation, chemotaxis, and degranulation, which are typically depressed in newborn infants. IP3 generation can be stimulated by N-formyl-methionyl-leucylphenylalanine (fMLP) tripeptide, which mimics the naturally occurring bacterial oligopeptides. In this study both neonatal and adult polymorphonuclear leukocytes were stimulated by fMLP (1 x 10(-6) M) and the levels of IP3 were assayed by a specific radiometric method. The time course of IP3 generation was studied for up to 60 s in a total of 10 samples. The response appeared reduced in cord blood samples. To confirm this observation, we extended our study to a larger number of samples, quantitating [IP3] at the time peak of 10 s. As expected IP3 generation was significantly (F test, p < 0.0001, n = 39) lower in newborns than in adults (means +/- SD = 0.64 +/- 0.25; 1.26 +/- 0.36, ng/10(6) cells, respectively). Besides soluble stimulus, neutrophils were treated with a particulate stimulus, namely serum-treated zymosan, which is also able to stimulate IP3 synthesis from polymorphonuclear leukocytes. Serum-treated zymosan produced a prolonged elevation in the level of IP3, reaching a plateau within 120 s in both cord blood and in control samples.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Leukotriene B4 (LTB4) is a potent mediator of inflammation generated by polymorphonuclear leukocytes (PMN) in response to an appropriate stimulus. It acts as a chemoattractant and stimulates PMN functions, amplifying their inflammatory response. Newborn infants show an increased susceptibility to infections in which PMN dysfunctions play the main role. In this work, LTB4 release from neonatal polymorphonuclear cells was assessed to investigate whether a defect was detectable. Blood was obtained from the umbilical cord of 10 full-term healthy neonates and 10 adult controls. The LTB4 production from purified PMN suspensions was induced by three different stimuli: the calcium ionophore A23187, serum-treated zymosan, and formyl-methionyl-leucyl-phenylalanine at final concentrations of 2 microM, 10 mg/mL, and 10 microM, respectively. The kinetics of LTB4 release were studied for up to 30 min by assaying the supernatants of the stimulated cells with a specific RIA. The LTB4 release, undetectable in resting PMN, was strongly stimulated by the A23187, peaking at 5 min, with significantly higher levels (t test, p < 0.01) in newborn than in adult PMN preparations (mean +/- SD: 12.46 +/- 2.96 and 6.21 +/- 2.09 ng/10(6) cells, respectively). In comparison, serum-treated zymosan-stimulated PMN released smaller amounts of LTB4. The levels peaked at 10 min and were significantly (t test, p < 0.01) lower in newborn than in adult samples (mean +/- SD: 0.71 +/- 0.22 and 3.19 +/- 1.06 ng/10(6) PMN, respectively). Finally, when the PMN were stimulated by formyl-methionyl-leucyl-phenylalanine, the release of LTB4 was highly variable both in newborn and in adult samples, as previously reported.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The aim of the study was the evaluation of the relationship between chemical fat analysis and some more rapid tests proposed to estimate steatorrhoea. Stool collections (72 h) were obtained on 32 occasions in 22 patients with cystic fibrosis and in seven healthy children. A very close relationship was found between faecal fat, as measured by standard chemical methods, and faecal energy (r = 0.95, P < 0.001). We conclude that the determination of faecal energy, easier to measure than faecal fat, can provide reliable information about the extent of steatorrhoea in cystic fibrosis.

Abstract
In 10 children with cystic fibrosis and persisting steatorrhoea, supplementation with taurine (30-40 mg/kg/day) was given for two months as an adjunct to the usual pancreatic enzyme treatment. A three day fat and energy balance was performed in patients with cystic fibrosis, before and after the supplementation, and in seven healthy controls who did not receive taurine. Faecal fat was measured by a gravimetric method and stool energy was determined using a bomb calorimeter. Patients with cystic fibrosis, before and after taurine, and healthy controls received the same fat and energy intake (calculated by a dietitian). In patients with cystic fibrosis taurine did not produce any improvement of steatorrhoea (mean (SD) faecal fat 8.7 (3.3) v 11.2 (7.0) g/day, respectively before and after the supplementation), of faecal energy loss (0.978 (0.468) v 1.133 (0.539) MJ/day), of faecal fat expressed as percent of fat intake (13.4 (5.6) v 15.1 (9.8)%), and of faecal energy expressed as percent of energy intake (9.9 (3.6) v 11.2 (5.7)%). Healthy controls had significant lower fat (3.5 (2.3) g/day) and energy 0.576 (0.355) MJ/day faecal losses. In conclusion, taurine failed to decrease significantly fat and energy losses. Our study does not support the use of taurine supplementation in the nutritional management of cystic fibrosis.

Abstract
Seventeen paediatric patients with immunodeficiency syndromes (10 with selective IgA deficiency, four with panhypogammaglobulinaemia, and three with selective T cell deficiency) were investigated for bacterial overgrowth of the small intestine and gut permeability to macromolecules. Five of 12 patients showed viable bacterial counts of more than 2 x 10(5)/ml in jejunal fluid. Bacterial overgrowth was also confirmed indirectly by breath hydrogen determination, which was higher than 10 ppm in four of the five patients with positive jejunal culture. Gut permeability to lactulose and L-rhamnose was abnormal in 16 of the 17 immunodeficient patients, who also had higher mean urinary excretion ratios than control subjects-mean (SD) values were 0.216 (0.160) and 0.029 (0.002), respectively. These studies indicate that bacterial overgrowth of the small intestine is a common feature in immunodeficient patients, regardless of the immunological abnormality. Moreover, these patients have an increased gut permeability to macromolecules.

Abstract
Thirty jaundiced neonates with diarrhoea who were being treated with phototherapy and 30 matched control infants were studied to try and find out the cause of the diarrhoea. Faecal osmolality and electrolyte concentrations were measured, which gave clear evidence that the diarrhoea arose from intestinal secretion. Rectal water and electrolyte absorption in 10 jaundiced infants receiving phototherapy, in 10 jaundiced infants not receiving phototherapy, and in 10 healthy controls was measured with a rectal dialysis bag. A further group of eight jaundiced infants was also studied both during and after phototherapy to document the reversal of ion transport changes. Absorption of water, sodium chloride, and potassium was significantly impaired in the patients receiving phototherapy compared with each of the control groups. Such impairment was transient, as it was not apparent when the jaundice faded and phototherapy was stopped. These data show that the colon plays a part in the pathogenesis of secretory diarrhoea and that both hyperbilirubinaemia and phototherapy are necessary for such an effect to develop.

Abstract
The effect of short-term immunosuppressive treatment on the percentage of circulating DR-bearing T cells was investigated in 16 children with HBsAg-positive chronic active hepatitis. DR-positive T cells, thought to represent activated T cells, were significantly increased in all patients as compared to 10 age-matched controls [14.5 +/- 4.2% (mean +/- SD) vs. 0.4 +/- 0.1%, p less than 0.001]. Fifty-six percent of patients showed a decrease in the percentage of DR-positive T cells after 72 h of prednisone therapy. A response did not correlate with the presence of HBeAg, anti-HBeAg, or anti-delta antibodies. There was an inverse relationship (r = -0.56; p less than 0.05) between the decrease of the percent of DR-positive T cells during immunosuppression and pretreatment alanine aminotransferase levels. The persistence of high levels of circulating DR-bearing T cells during therapy may represent the immunological counterpart of more severe disease, and of nonresponsiveness to corticosteroids.

Abstract
The perinatal histories of 27 newborn infants with NEC were compared to those of 54 infants of equivalent birth weight who did not have NEC during an 8-year study period to see if possible predisposing factors were independent of the confounding effect of birth weight. No differences were observed in gestational age, degree of intrauterine growth retardation, premature rupture of membranes, perinatal asphyxia, skin temperature at admission, haematocrit, presence or absence of respiratory distress syndrome, umbilical catheter placement, start and type of feeding or presence of positive blood cultures. Prematurity is the greatest risk factor predisposing to the development of NEC and the perinatal problems which precede the onset of NEC are common among all premature infants.

Abstract
This study was performed to determine whether covering the eyes with an opaque screen over the head end of the bassinet instead of the normal patch would improve the behavioral organization of jaundiced, but otherwise healthy, term infants treated with phototherapy. 38 matched infants were randomly assigned to have a patch or a screen. Serum bilirubin at the time of observation was 11.2-17.5 mg/100 ml (mean = 13.7, patch) and 9.4-16.4 mg/100 ml (mean = 13.4, screen). 19 infants, of whom 11 were jaundiced (6.2-14.3 mg/100 ml, mean = 10.3), served as control subjects. The infants were examined with the Brazelton scale on the 3rd day after birth, when the patch subjects had been under blue light from 6 to 45 h (mean = 23.9), and the screen subjects from 6 to 61.5 h (mean = 22.6). The control subjects scored better (all differences, p less than 0.05) than the patch subjects on inanimate visual, animate visual, visual and auditory, alertness. The control subjects also did better than the screen subjects on inanimate visual, animate visual, animate auditory, visual and auditory, alertness, but poorer on motor maturity and consolability. The screen subjects did poorer than the patch subjects only on skin color lability. At 1 month of age, 9 sets of matched infants were examined. The only difference was that the control subjects did better than the patch subjects on animate visual and lability of state. Our data confirm the poorer short-term orientation performance of jaundiced infants treated with phototherapy but do not indicate that covering the eyes with an opaque screen improves behavioral organization.

Abstract
A sensitive radioimmunoassay for IgG gliadin antibodies is described. Serum specimens were added to wells of plastic microtitre plates coated with gliadin. After removal of the unbound material, gliadin antibodies were detected by adding 125I-labelled staphylococcal protein A (125I-SpA). Serum specimens from coeliac patients on a normal diet or on a gluten-free diet were tested, as well as sera from an age-matched control group. Measurements to obtain precise quantitative values were made with gliadin antibody-rich serum as reference standard. High titres of gliadin antibodies were found in 18 out of 19 coeliac patients on a normal diet (95%); in patients on a strict gluten-free diet serum values did not exceed 2 S.D. of the control mean. Due to the high sensitivity of the method a low but detectable amount of gliadin antibody was present in the sera of all controls.

Abstract
This study was performed in order to evaluate possible changes in behavior in jaundiced infants without perinatal complications other than hyperbilirubinemia treated with phototherapy. Thirty jaundiced infants (mean bilirubinemia 13.3 mg/100 ml, range 8.4-17.5) born spontaneously at term and undergoing phototherapy for 6 h or more, and 30 comparison subjects similar for sex, birthweight, gestational age, Apgar score, obstetrical history and father's profession were examined during the 3rd day of life according to Brazelton Neonatal Behavior Assessment Scale (BNBAS). For 6 of 26 items we found higher values for comparison group (Wilcoxon's Test): inanimate visual median (m.) 5 vs. 3 (P less than 0.05); animate visual m. 5 vs. 3.5 (P less than 0.01); visual and auditory 5.5 vs. 4 (P less than 0.005); pull-to-sit m. 6 vs. 5 (P less than 0.01); cuddliness m. 5 vs. 4 (P less than 0.01); alertness m. 5 vs. 4 (P less than 0.005). Visual orientation responses were the most compromised. On the 4th day of life, 14 infants who had terminated phototherapy at least 2 h before (mean 9.9 h) were compared with their matched comparison group subjects and the same significantly poorer performances, mainly in visual orientation, were found. At one month of age, 12 of these infants treated with phototherapy still showed a significantly poorer performance in 2 items of orientation: inanimate visual m. 6 vs. 4.5 (P less than 0.05); visual and auditory m. 6.5 vs. 4 (P less than 0.05). Whether these results depend on the jaundice or on the phototherapy remain to be established.

Abstract
Evidence is accumulating which indicates that immune reactions to gliadins are involved in the pathogenesis of celiac disease, as humoral- and cell-mediated immune responses to gliadins have been demonstrated in the jejunal mucosa and the peripheral blood of patients. An abnormal specific immunological response to gliadins is demonstrated not only in celiac children but also in their first-degree relatives. Seventy-eight percent of celiac patients, and 67, 87, and 100% of their fathers, siblings, and mothers, respectively, have a peripheral blood lymphocyte population reacting in vitro with a proliferation response to at least one of four peptide mixtures obtained from bread and durum wheat gliadins using a procedure simulating in vivo protein digestion. The specificity of this immunological hyperresponsiveness against wheat gliadins is shown by two sets of data: (a) Lymphocytes from celiac children and their relatives were much less sensitive to peptides from rice prolamin and not at all sensitive to peptides from wheat albumins. (b) Only 7% of 30 adult controls had a proliferative response of their peripheral lymphocytes to wheat gliadin peptides. It is not known at this time if healthy relatives of celiac patients mount an immune response against the intestine in vivo. However, it is possible that the presence of lymphocytes reactive to wheat gliadin peptides in apparently healthy relatives of celiac patients may explain why these relatives develop histologic evidence of celiac disease when their gluten intake is increased (Doherty M, Barry RF. Lancet 1981;1:517-20).

Abstract
Four patients with common, variable agammaglobulinemia were preveiously reported to have normal numbers of circulating B lymphocytes which synthesized normal amounts of IgG in tissue culture but failed to secrete the newly synthesized IgG. The B lymphocytes of these patients fail to incorporate [3H]mannose and/or [3H]glucosamine into newly synthesized IgG, whereas such incorporation appears to occur just before IgG secretion in cultures of normal B lymphocytes.

Abstract
A peptide consisting of 10 amino acids derived from the CH3 region of human IgG was shown to bind to monocytes and to inhibit rosette formation of antibody-coated erythrocytes with human monocytes. Two myeloma proteins of the IgG1 and IgG3 subclass, both with known deletions in the CH2 region of the gamma chain, showed unimpaired ability to bind to monocytes. These experiments suggest that the isolated peptide represents the primary site of attachment of IgG to monocytes.

Abstract
The digestibility of various starches has been studied in normal infants of different ages. During balance periods of 3 days, while the infants were receiving known dietary quantities of the starch to be tested, the fecal content of lactic acid, glucose, dextrins, and starch was measured. After the first year of life, children were able to absorb almost completely 170 gm/m2 of body surface of cooked wheat starch given in the form of biscuit or macaroni. A lower absorption coefficient was found for potato starch given in the form of biscuit. Cooked wheat, tapioca, corn, rice, and potato starch in amounts of 45 and 85 gm/m2/day, respectively, for 1- and 3-mo-old infants, were almost completely absorbed. In 1-mo-old infants larger amounts (110 gm/m2/day) of cooked rice starch were well tolerated; it should therefore be possible to provide a large part of the carbohydrate requirements of infants from the first month of life with cooked starches.
