Hepatology is an important specialty with diseases and complications related to viral hepatitis and alcohol being the main reason for seeking specialist advice.
On most general medical rotations and on most surgical wards there are patients with hepatological problems. Clinical Cases Uncovered contains clinical presentations with real-life patient cases and outcomes as seen on the wards and in exams, and leads students through a practical approach to diagnosis and management of hepatological disease.
Following a question and answer approach, including self-assessment material and a 'refresher' section on the basic science, Hepatology: Clinical Cases Uncovered features investigations and the treatment options available for patients presenting with hepatological problems. Difficult concepts are clarified and relevant links are made between pathology and clinical presentation. Clinical Cases Uncovered is ideal for medical students, junior doctors on the Foundation Programme, GP trainees, residents, specialist nurses and nurse practitioners.
The book is also an ideal refresher for hepatology or gastroenterology trainees at the beginning of their specialist training programme. Nash, Southampton General Hospital; I.

List of abbreviations. Part 1 Basics. Basic science. Approach to the patient.
Part 2 Cases. Patients with acute liver disease. Case 1 A year-old man presenting with jaundice. Case 2 A year-old man with nausea, vomiting and jaundice. Case 3 A year-old women presenting with severe right upper quadrant pain and jaundice.
Case 4 A year-old man with painless jaundice.
Case 5 A year-old woman with vomiting and epigastric pain. Case 6 A 4-week-old baby with jaundice and failure to thrive. Hepcidin binds ferroportin resulting in internalization and proteosomal degradation.
This decrease in ferroportin results in decreased iron influx. In fetuses with GALD, liver injury results in significantly decreased production of hepcidin.
About the Author
In addition, transferrin gene expression is decreased, resulting in reduced iron binding capacity. The result is fetal iron overload and an excess of circulating non-transferrin bound iron NTBI.
The tissue distribution of extrahepatic siderosis in the NH phenotype seems to be a function of the ability of various tissues to manage excess circulating NTBI.
Tissues that are unaffected by siderosis express ferroportin, which permits iron export. Thus, extrahepatic tissues that are ZIP14 positive and ferroportin negative are uniquely susceptible to siderosis.
Reticuloendothelial cells are spared siderosis because they express ferroportin, which in the state of hepcidin paucity is fully active. Hepatocytes express transporters for transferrin bound iron and NTBI, and ferroportin. Accrual of hemosiderin in hepatocytes is likely to be a function of injury and perhaps relatively reduced ferroportin expression or function. Renal hypoplasia with dysgenesis of proximal tubules and paucity of peripheral glomeruli has been described in infants with NH.
Expansion of the proximal tubule and associated glomeruli from the 24th week of gestation onward is dependent upon angiotensinogen, which is synthesized exclusively by the liver. In a study of livers and kidneys from infants with GALD-NH, hepatocyte mass and angiotensinogen gene expression were markedly reduced relative to normal.
Liver expression of angiotensinogen inversely correlated with proximal tubule density. Therefore, it appears that alloimmune liver injury leads to reduced hepatocyte mass, which results in reduced angiotensinogen production, which in turn leads to defective renal development.

For the other diseases, fetal liver injury resulting in impaired regulation of placental iron flux is hypothesized to cause NH. Clinical findings GALD can present anytime from 18 weeks gestation to 3 months post-delivery. The majority of infants present with liver failure within hours of birth. NH is one of the most common causes of liver failure in the neonatal period.
They may have renal involvement and be oliguric. There is frequently a history of intrauterine growth restriction, oligohydramnios, and prematurity. In rarer cases, liver disease may take days to weeks to present. Affected twins may have different clinical presentations; with one twin severely affected and the other minimally so. Other processes that can cause neonatal liver failure include mitochondrial diseases, bile acid synthetic defects, tyrosinemia, hemophagocytic lymphohistiocytosis, ABCB11 gene mutations, hereditary galactosemia, hereditary fructose intolerance, and infection.
Clinically, NH infants are unique in that they have evidence of fetal insult and neonatal liver failure. They are extremely coagulopathic, but have low serum aminotransferases in contrast to infants with virally induced acute liver failure who have extremely high serum aminotransferases.
Infants with GALD-NH may be misdiagnosed as having tyrosinemia due to elevated tyrosine levels, but they do not have succinylacetone in the urine. Infants with NH may also be misdiagnosed as having a bile acid defect; however, they will not have the classic pattern of bile metabolites found in serum and urine by mass spectroscopy.
Finally, infants with GALD-NH should not have markedly elevated lactate levels as seen in infants with mitochondrial abnormalities. Diagnosis GALD should be suspected in infants who manifest liver disease antenatally or in the immediate post birth period. It should also be considered in cases of unexplained stillbirth, neonatal demise, or early infant death.
GALD is likely underdiagnosed. In cases of stillbirth or fetal loss, practitioners may not think to look for GALD before the index living case with NH occurs.
Likewise, in live infants, symptoms of liver failure may be confused with those of global sepsis and practitioners may have difficulty making a diagnosis of NH with currently available tools.
Global knowledge of this disorder and its wide spectrum of presentations may help to increase the number of cases that are accurately diagnosed.
Diagnosis of NH rests upon diagnosing extrahepatic siderosis: the complex of severe liver disease and extrahepatic siderosis defines the condition. Siderosis in the liver alone is not diagnostic as the normal newborn liver can contain quantities of iron that are stainable though quantitatively different to an experienced pathologist.
In addition, pathologic hepatic siderosis can be seen in several neonatal liver diseases. There is no known value of iron content in the liver which can accurately discriminate between NH and other causes of neonatal iron overload.
Likewise, absence of liver siderosis does not rule out NH, as some GALD infants may have acute injury without iron overload and other GALD cases are associated with complete hepatocyte destruction, which precludes hepatic siderosis. Glandular tissue containing iron can most easily be obtained from a biopsy of the oral mucosa.
Bleeding, which may potentially be made worse by coagulopathy, is controlled by local measures and has not been a serious problem in any case. No fresh frozen plasma or recombinant factor VII is necessary beforehand. One must be sure to obtain a specimen that contains submucosal glands.They are extremely coagulopathic, but have low serum aminotransferases in contrast to infants with virally induced acute liver failure who have extremely high serum aminotransferases.
