Glucose-6-phosphate dehydrogenase deficiency and neonatal jaundice in Jamaica.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency was detected in 16 (69.6%) of a group of 23 neonates who had unexplained moderate or severe jaundice. This proportion is significantly more than the 9.4% observed or the 22.2% expected in Jamaican neonates who are not moderately or severely jaundiced (P less than 0.003), and significantly more than the 12.6% observed or the 21.0% expected in older Jamaican children and adults (P less than 0.003). Phenobarbitone therapy and phototherapy reduced the need for exchange transfusion but this was necessary in eight patients. Two babies developed kernicterus and one died. On the other hand, only two of 21 neonates who were identified as G6PD deficient at birth subsequently became moderately or severely jaundiced, and this could be attributed to other causes in both cases. These findings indicate that apparently spontaneous neonatal jaundice is important in infants who have the G6PD A--enzyme. However, the jaundice is probably precipitated by unknown factors to which the G6PD deficient neonate is more susceptible than the infant who is not G6PD deficient. THere is also a slightly increased incidence of G6PD deficiency in neonates who develop jaundice because of ABO or Rh(D) iso-immune disease, infection or prematurity.

Renal function and other factors in obstructive jaundice.

Renal function and other factors that possibly affect the outcome of operation were measured in 24 patients with obstructive jaundice and in 15 non-jaundiced controls. The preoperative features that were associated with a poor postoperative recovery from obstructive jaundice were a raised serum fibrinogen/fibrin degradation product concentration, infection, hypoalbuminaemia and a low glomerular filtration rate. Preoperative serum fibrinogen/fibrin degradation product concentrations were raised in 4 of the 6 jaundiced patients who died after surgery but in none of the controls, in whom there was no mortality. In the jaundiced patients there was a greater incidence of postoperative renal impairment than in the controls. All patients were given mannitol during operation. Further mannitol was required after surgery in 13 of the 24 jaundiced patients in order to maintain urine flow rate despite adequate intravenous fluids being given. In contrast, only 1 of the 15 control patients required post operative mannitol. It is emphasized that repeated doses of mannitol can lead to a profound natriuresis and adequate intravenous saline should be given.

Does obstructive jaundice adversely affect wound healing?

The effect of obstructive jaundice on wound healing has been investigated in an experimental study of abdominal wounds in rats following ligation and division of the common bile duct. Animals were jaundiced for 2 weeks before a second operation at which the abdominal wounds were made. The wounds in jaundiced and control animals showed no significant differences in mechanical strength during a 21-day period of study but there was a significant delay in the accumulation of collagen in the wounds of jaundiced animals. The findings suggest that the biochemical changes in the wounds of jaundiced animals did not interfere with wound repair and cast doubt on the thesis that jaundice has an adverse effect on wound healing.

Ultrasound in the evaluation and diagnosis of jaundice.

Our experience in the evaluation and diagnosis of jaundice by ultrasound in a consecutive series of patients examined in the past year is reported. A final diagnosis is available in 49 patients with obstructive jaundice and 41 patients with nonobstructive jaundice. The accuracy of separation into these two groups is 97% in this series. We would like to stress the value of ultrasound as a complete investigation in many jaundiced patients. In this series a full diagnosis of the cause of jaundice was achieved in 58% of patients.

[Cholestatic jaundice and hypophosphataemia in parenterally-fed premature infants--coincidence or causal connection? (author's transl)].

A report is presented of the chemical pathological findings in 14 premature and one full-term infant receiving almost exclusively parenteral nutrition during the first two weeks of life. Six infants developed cholestatic jaundice. The underlying diseases were the idiopathic respiratory distress syndrome in 10, gastroschisis in 3 and renal insufficiency in 1, while one was an otherwise healthy small for dates infant. After parenteral nutrition had been discontinued obstructive jaundice cleared by the third month of life except in one infant. Apart from the higher glucose intake during the second week, jaundiced infants principally differed from non-jaundiced infants by the development of significant hypophosphataemia. An attempt was made to correlate aetiologically the presence of cholestatic jaundice with the finding of hypophosphataemia on the possible basis of a disturbance of energy metabolism.

[Abnormal lipoprotein (LP-X) in the first months of life with particular reference to obstructive jaundice (author's transl)].

Abnormal lipoprotein (LP-X) represents a specific parameter for the presence of obstructive jaundice in the adult. Since LP-X has also been detected in the serum of newborn infants, both full-term and premature, and in early infancy, in the absence of clinical evidence of obstructive jaundice, extensive investigations were undertaken in infants during the neonatal period to clarify this phenomenon. The present study reports the data obtained in over 2000 sera from over 370 infants (mature newborn and premature newborn and young infants), tested more or less continuously by means of the Rapidophor method, initially on a qualitative, and subsequently, on a semi-quantitative basis. LP-X appears within the first fortnight in newborn infants, irrespective of the mode of feeding. The LP-X concentration was correlated to the birth weight. Premature infants displaying signs of immaturity possessed markedly higher LP-X levels than mature newborn infants. LP-X was not correlated to the alkaline phosphatase level, nor to the gammaglutamyl transferase activity; the bilirubin level, likewise, had no connection with the LP-X concentration. Patients with proven obstructive jaundice showed distinctly higher LP-X concentrations (greater than 56 mg/100 ml), whereby the rise in LP-X level in some cases preceded the appearance of the clinical manifestations of obstructive jaundice. The following hypotheses are advanced in order to explain the presence of LP-X during the neonatal period and are discussed on the basis of clinical observations in adults, the physiological conditions in the newborn infant and the results of the present study: The liver, which occupies the central position amongst metabolic organs, also in the case of the lipoproteins, is at a physiological stage of organic and functional maturation during this early period of life. Under these circumstances, a pseudo-obstructive mechanism on the basis of insufficient excretion of biliary lipoproteins, in conjunction with a simultaneous "physiological" deficiency of lecithin: cholesterol acyl transferase could lead to the appearance of LP-X in the serum. Catabolism of the resultant LP-X cannot take place owing to an inadequate activity of lipoprotein lipase. Functional immaturity can be presumed in the case of both enzyme systems during the neonatal period. On attainment of a degree of maturity compatible with the appropriate neonatal stage, the LP-X values become negative between the 7th and the 16th week of life. It is conceivable that the appearance of LP-X in the newborn infant can be ascribed to LP-X1, since the "physiological" LP-X concentrations in the neonatal period (values of up to 20 mg/100 ml) are distinctly lower than the values found in obstructive jaundice. LP-X determination can be rated as a useful supplementary investigation in the differential diagnosis of extrahepatic biliary atresia during the first weeks or months of life...

[Clinical and experimental study on hepatorenal syndrome in terms of obstructive jaundice (author's transl)].

In our department, hepatorenal syndrome was highly associated with obstructive jaundice and was seen in 9.2 percent of patients with obstructive jaundice. This syndrome developed when in underlying hepatic disease, acute renal failure supervened. Histological findings of renal failure caused by obstructive jaundice were summarized as tubular necrosis and the presence of protein-like substance in the glomerulus, which were mostly reversible and similar to those seen in shock. To investigate the pathogenesis of hepatorenal syndrome, experimentally the common duct in dog was ligated to produce obstructive jaundice and B. Klebsiella was injected into the bile duct to produce cholangiolitis. From this study, it was evident that cholangiolar infection was closely correlated with the manifestation of renal failure. In fact, without acquiring infection, renal failure did not occur. Moreover, this infection produced endotoxemia with high incidence. Therefore, it is assumed that this cholangiolar infection plays an important role in the pathogenesis of hepatorenal syndrome caused by obstructive jaundice.

Post-traumatic hepatic dysfunction as a major etiology in post-traumatic jaundice.

Thirty-eight patients who had sustained acute trauma, profound hemorrhagic shock, and massive transfusion were studied prospectively to determine the predominant etiologic factors in the development of post-traumatic jaundice. An analysis of clinical and biochemical factors occurring in association with each bilirubin peak in the postoperative course found the jaundice related to transfusion and surgery in 11 instances, to sepsis and septicemia in 15 instances, and to hepatic dysfunction in 23 instances. Results indicated that admission estimates of SGOT and LDH levels, the height of the bilirubin peak and the postoperative day on which it occurs, and the white cell count and GGT at the time of the peak may be of use in the differential diagnosis. Four case reports were used to emphasize the fluctuating pattern of jaundice and the different etiologic factors that may predominate. Light and electron microscopy from three patients illustrated the structural alterations that accompany the biochemical impairment of liver function and enable a more precise appreciation of this syndrome. Hepatic dysfunction appears to be implicated in a high proportion of patients who develop post-traumatic jaundice, which frequently occurs as part of a spectrum of multiple organ failure.

Glucagon stimulated plasma cyclic adenosine-3',5'-monophosphate in the differential diagnosis of jaundice.

The amount of plasma cyclic adenosine-3',5'-monophosphate was estimated before and 15 minutes after the intravenous injection of 1 milligram of glucagon in 34 patients with obstructive and in 23 patients with nonobstructive jaundice. After stimulation with glucagon, the median adenosine-3',5'-monophosphate concentration in obstructive jaundice rose fortyfold or more, while in nonobstructive jaundice, the increase was twentyfold or less. The difference was highly significant. The results indicate that this test can be useful in the differential diagnosis of obstructive and nonobstructive jaundice.

Urinary tract infection presenting with jaundice.

Jaundice was the presenting feature in an 8-year-old girl suffering from urinary tract infection (UTI) due to Escherichia coli. The jaundice cleared with the cure of the infection. The mechanisms of jaundice complicating UTI are discussed, and the importance of urine culture in infants and children with jaundice is stressed.

The accelerated diagnosis of jaundice with ultrasonography and narrow-needle cholangiography.

The accuracy of ultrasonography in the diagnosis of jaundice in 70 patients has been compared with that of transhepatic cholangiography and the results of surgery and liver biopsy. A simplified system of grouping the ultrasonic data is presented. The results indicate that ultrasonography is capable of differentiating obstructive from non-obstructive jaundice in 94% of cases and of defining the correct anatomical level in 85% of cases. The accuracy of narrow-needle cholangiography was 100% for obstructive jaundice and 66% normal duct entry rate for non-obstructive jaundice.

The role of grey scale ultrasonography in the investigation of jaundice.

Sixty-seven patients were prospectively studied using grey scale ultrasound (GSU) to assess its possible role as part of a jaundice investigation programme. All scans were performed by one radiologist, without clinical information. When intrahepatic ductal dilatation was found an attempt was made to establish the level and cause of obstruction. The calibre of the intrahepatic bile ducts was correctly reported in 66 patients (98 per cent). Forty-three proved to have extrahepatic cholestasis, 24 had intrahepatic cholestasis. No patient with intrahepatic cholestasis had dilated ducts seen on ultrasound. In 43 patients with obstructive jaundice, GSU accurately detected the level of obstruction in 28. This accuracy varied with the cause of obstruction. A direct indication of diagnosis was possible in 45 of the 67 patients. In a unit specializing in the management of complicated hepatobiliary problems, GSU has been shown to be accurate in differentiating extra- from intrahepatic jaundice. Being non-invasive, it appears ideally suited for use as a screening procedure, permitting selection of appropriate invasive investigations to provide complete preoperative imaging of the biliary tree. In patients with jaundice due to gallstones, GSU may be the only imaging technique required before surgery provided good operative cholangiography is available.
