We have characterized the clinical and biochemical features of three siblings of a kindred with severe hypertriglyceridaemia due to apolipoprotein C-II (apo C-II) deficiency caused by the mutation described as apo C-IIHamburg. The clinical syndrome is characterized by recurrent pancreatitis in two of three affected individuals, with discrete hepatosplenomegaly in all three patients and cholelithiasis in one. Eruptive xanthomas and lipemia retinalis were absent. Plasma lipoproteins were characterized by fasting chylomicronaemia, reduced low density lipoproteins (LDL) and low high density lipoproteins (HDL). The marked hypertriglyceridaemia could be corrected promptly by infusion of normal plasma. Apolipoprotein C-II (apo C-II) levels in homozygotes were very low (0.01 mg dl-1), and mean apo C-II levels in heterozygotes were lower (2.08 +/- 0.11 mg dl-1) than in normal family members (3.38 +/- 0.75 mg dl-1). Lipoprotein lipase and hepatic triglyceride lipase activities in post-heparin plasma were normal. Zonal ultracentrifugation revealed a marked increase in triglyceride-rich lipoproteins and reduced LDL and HDL. LDL consisted of two fractions with higher hydrated density of the main fraction compared with normals with a trend to normalization on a fat-free diet. The molecular defect in the apo C-II Hamburg gene has been previously identified as a donor splice site mutation in the second intron. This leads to abnormal splicing of the apo C-II Hamburg mRNA and apo C-II deficiency in plasma. The mutation causes the loss of an HphI restriction enzyme site present in the normal apo C-II gene.(ABSTRACT TRUNCATED AT 250 WORDS)

Sonographic examination of the abdomen was performed in 20 patients with cystic fibrosis aged 3--41 years. The predominant acoustic architecture of the pancreas was one of moderate to markedly increased echogenicity when compared to the liver at the same depth. Increased echogenicity of the pancreas was independent of the presence of malabsorption. The usual reduced echo pattern associated with pancreatic inflammation was seen in only one of five cystic fibrosis patients with clinical evidence of pancreatitis. Other pancreatic abnormalities included pancreatic calcifications in one child with pancreatitis and a pseudocyst in an adult with pancreatitis. Eight patients had hepatosplenomegaly and gallstones were seen in two; one had a markedly contracted gallbladder. Sonography offers an effective method of following patients with cystic fibrosis.

A survey of all patients in whom liver biopsy showed epithelioid granulomas was undertaken at two major teaching hospitals in Glasgow for the period 1970-1979. Seventy-seven patients with hepatic granulomas were studied retrospectively. In 53 cases (69 per cent) a clear-cut clinical diagnosis was established, which included sarcoidosis (eight cases), tuberculosis (eight), extrahepatic biliary obstruction (seven), primary liver diseases (11), neoplasm (six), bacterial infection (five) and miscellaneous (eight). In 24 patients (31 percent) no cause was found. Seventeen patients from this idiopathic group were studied prospectively and single examples of the following conditions were subsequently diagnosed; pulmonary tuberculosis, primary biliary cirrhosis, ulcerative colitis, adenocarcinoma of rectum, primary hepatocellular carcinoma, alpha-one antitrypsin deficiency and pulmonary fibrosis, sarcoidosis, pulmonary fibrosis alone, gallstones, rheumatic heart disease, unexplained hepatosplenomegaly and one death from mesenteric artery thrombosis. Only six cases remained truly idiopathic. Three of these patients recovered and in two liver biopsy became normal. The other three have persistent granulomas associated with continuing illness.

Congenital dyserythropoietic anemia type II (CDA-type II) (HEMPAS) was reported in three siblings. CDA-type II was associated with marked hepatosplenomegaly and siderosis of both organs. All three sibling developed cholelithiasis with choledocholithiasis and obstructive jaundice in two of them. Anemia showing hemolytic component with sequestration of erythrocytes in the spleen was corrected after splenectomy without the need of blood transfusions during the follow up period of 20, 11 and 11 years. Ultrastructural investigation of the erythrocytes after splenectomy revealed increased number of erythrocytes showing the double membrane phenomenon.

In this article, we report the case of a 16-month-old German boy who was admitted to the Children's Hospital of Stuttgart with a 4-week history of intermittent fever, decreased appetite, weakness, fatigue, and difficulty sleeping. He was healthy at birth and remained so for the first 15 months of his life. On admission, physical examination showed enlarged cervical, axillary, and inguinal lymph nodes, as well as hepatosplenomegaly. Laboratory data revealed pancytopenia, elevated liver function tests, and hypergammaglobulinemia. Blood, stool, and urine culture results were negative. Viral infections and rheumatologic and autoimmune disorders were ruled out, but a positive titer for Leishmania antibodies was noted. In a liver and bone marrow biopsy, the amastigote form of the parasite could not be seen in cells. The promastigote form of Leishmania was found and the diagnosis of visceral leishmaniasis was made by combining the cultures of both the liver and the bone marrow biopsy material in 5 mL 0.9% saline on brain heart infusion agar, supplemented with defibrinated rabbit blood and incubated at 25 to 26 degrees C for 5 days. The parasite was identified by Southern blot analysis as Leishmania infantum. Specific therapy with the antimonial compound sodium stibogluconate with a dose of 20 mg/kg body weight was begun immediately. Within 4 days, the patient became afebrile. The side effects of treatment, including erosive gastritis, cholelithiasis, worsening hepatosplenomegaly, elevation of liver enzymes, pancreatitis, and electrocardiogram abnormalities, necessitated the discontinuation of treatment after 17 days. On discharge 4 weeks later, the patient was stabilized and afebrile with a normal spleen, normal complete blood count, normal gammaglobulins, and decreasing antibody titers to Leishmania. During the next 24 months, the patient experienced intermittent episodes of abdominal pain, decreased appetite, recurrent arthralgia, and myalgia. But at his last examination in January 1998, he was well; all symptoms mentioned above had disappeared. Because the child had never left Germany, nonvector transmission was suspected and household contacts were examined. His mother was the only one who had a positive antibody titer against Leishmania donovani complex. She had traveled several times to endemic Mediterranean areas (Portugal, Malta, and Corse) before giving birth to the boy. But she had never been symptomatic for visceral leishmaniasis. Her bone marrow, spleen, and liver biopsy results were within normal limits. Culture results and polymerase chain reaction of this material were negative. A Montenegro skin test result was positive, indicating a previous infection with Leishmania. Western blot analysis showed specific recognition by maternal antibodies of antigens of Leishmania cultured from the boy's tissue. Visceral leishmaniasis is endemic to several tropical and subtropical countries, but also to the Mediterranean region. It is transmitted by the sand fly (Phlebotomus, Lutzomyia). Occasional nonvector transmissions also have been reported through blood transfusions, sexual intercourse, organ transplants, excrements of dogs, and sporadically outside endemic areas. Only 8 cases of congenital acquired disease have been described before 1995, when our case occurred. In our patient, additional evaluation showed that the asymptomatic mother must have had a subclinical infection with Leishmania that was reactivated by pregnancy, and then congenitally transmitted to the child. Visceral leishmaniasis has to be considered in children with fever, pancytopenia, and splenomegaly, even if the child has not been to an endemic area and even if there is no evidence of the disease in his environment, because leishmaniasis can be transmitted congenitally from an asymptomatic mother to her child.

Hemobilia is a hemorrhage into the biliary tract that may follow surgical trauma, liver biopsy, aneurysms, extra- or intra-hepatic tumors of the biliary tract, gallstones, and inflammatory lesion of liver, especially helminthic or pyogenic. Sometimes, it is associated with primary liver cancer. An 84 year-old woman was admitted because of continuous right upper quadrant pain 4 days before admission. Physical examination revealed decreased skin turgor, icteric sclerae and severe tenderness on right upper quadrant abdomen. She had no hepatosplenomegaly, and no rebound tenderness. She has been taking warfarin for 3 weeks before admission because of atrial fibrillation. On admission, serum bilirubin and transaminase were elevated. The level of hemoglobin and hematocrit were 11.3 g/dL and 37.4%, respectively. HBsAg was negative, but IgG anti-HBc and anti-HBs were positive and anti-HCV was negative. Parasite skin test and stool ova count demonstrated non-specific findings. Stool occult blood was strongly positive, and prothrombin time was markedly prolonged. According to endoscopic retrograde cholangiopancreatography, common bile duct was dilated, and filled with blood clot but there was no stone in bile tree. After two weeks, serum transaminase, bilirubin, hemoglobin, hematocrit, and CA19-9 were normalized. We report a case of hemobilia, occurring in a patient with continuous warfarin use.

ABCB4 (MDR3), a lipid translocator, moves phosphatidylcholine from the inner to the outer leaflet of the canalicular membrane. Genetic mutations of ABCB4 lead to three distinct but related hepatobiliary diseases. Progressive familial intrahepatic cholestasis (PFIC) type 3 is a chronic cholestatic syndrome characterized by a markedly elevated gamma-glutamyltranspeptidase. Patients present with jaundice, pruritus, and hepatosplenomegaly. Periportal inflammation progresses to biliary cirrhosis and causes portal hypertension. Ursodeoxycholic acid (UDCA) normalizes liver function tests in approximately one half of treated PFIC type 3 patients. Partial responders or nonresponders eventually will require liver transplantation. Gallstone patients with ABCB4 mutations may have low phospholipid-associated cholelithiasis syndrome, characterized by cholesterol gallstones and intrahepatic microlithiasis, along with recurrent biliary symptoms, despite cholecystectomy. Patients with ABCB4 mutations also may develop intrahepatic brown pigment stones. UDCA may improve biliary symptoms even before the dissolution of stones occurs. Additional therapies such as farnesoid X receptor ligands/agonists and benzfibrates show future therapeutic promise. Intrahepatic cholestasis of pregnancy affects pregnant women with abnormal ABCB4. These women suffer from disabling pruritus and also may experience steatorrhea. Fetuses are at high risk for prematurity and stillbirths. The definitive treatment is delivery of the baby. In the interim, limited fat intake, fat-soluble vitamin supplementation, and UDCA with or without S-adenosylmethionine can provide symptomatic relief. Additional hepatobiliary diseases related to ABCB4 mutations are likely to be identified. This may result in the discovery of additional therapies for PFIC type 3, gallstones, and intrahepatic cholestasis of pregnancy.

Beta-thalassemias are a group of hereditary blood disorders characterized by anomalies in the synthesis of the beta chains of hemoglobin resulting in variable phenotypes ranging from severe anemia to clinically asymptomatic individuals. The total annual incidence of symptomatic individuals is estimated at 1 in 100,000 throughout the world and 1 in 10,000 people in the European Union. Three main forms have been described: thalassemia major, thalassemia intermedia and thalassemia minor. Individuals with thalassemia major usually present within the first two years of life with severe anemia, requiring regular red blood cell (RBC) transfusions. Findings in untreated or poorly transfused individuals with thalassemia major, as seen in some developing countries, are growth retardation, pallor, jaundice, poor musculature, hepatosplenomegaly, leg ulcers, development of masses from extramedullary hematopoiesis, and skeletal changes that result from expansion of the bone marrow. Regular transfusion therapy leads to iron overload-related complications including endocrine complication (growth retardation, failure of sexual maturation, diabetes mellitus, and insufficiency of the parathyroid, thyroid, pituitary, and less commonly, adrenal glands), dilated myocardiopathy, liver fibrosis and cirrhosis). Patients with thalassemia intermedia present later in life with moderate anemia and do not require regular transfusions. Main clinical features in these patients are hypertrophy of erythroid marrow with medullary and extramedullary hematopoiesis and its complications (osteoporosis, masses of erythropoietic tissue that primarily affect the spleen, liver, lymph nodes, chest and spine, and bone deformities and typical facial changes), gallstones, painful leg ulcers and increased predisposition to thrombosis. Thalassemia minor is clinically asymptomatic but some subjects may have moderate anemia. Beta-thalassemias are caused by point mutations or, more rarely, deletions in the beta globin gene on chromosome 11, leading to reduced (beta+) or absent (beta0) synthesis of the beta chains of hemoglobin (Hb). Transmission is autosomal recessive; however, dominant mutations have also been reported. Diagnosis of thalassemia is based on hematologic and molecular genetic testing. Differential diagnosis is usually straightforward but may include genetic sideroblastic anemias, congenital dyserythropoietic anemias, and other conditions with high levels of HbF (such as juvenile myelomonocytic leukemia and aplastic anemia). Genetic counseling is recommended and prenatal diagnosis may be offered. Treatment of thalassemia major includes regular RBC transfusions, iron chelation and management of secondary complications of iron overload. In some circumstances, spleen removal may be required. Bone marrow transplantation remains the only definitive cure currently available. Individuals with thalassemia intermedia may require splenectomy, folic acid supplementation, treatment of extramedullary erythropoietic masses and leg ulcers, prevention and therapy of thromboembolic events. Prognosis for individuals with beta-thalassemia has improved substantially in the last 20 years following recent medical advances in transfusion, iron chelation and bone marrow transplantation therapy. However, cardiac disease remains the main cause of death in patients with iron overload.

BACKGROUND Cholesteryl ester storage disease (CESD), also known as lysosomal acid lipase deficiency (LAL-D), is a rare autosomal-recessive inheritable lysosomal storage disease. Since 2015, a causal treatment with sebelipase alfa, which replaces the missing LAL enzyme, has been approved. We report a fatal course of LAL-D in a female patient. CASE REPORT In 1979, CESD was first diagnosed in a 13-year-old female with marked hepatomegaly. At that time, no specific treatment for CESD was available and the spontaneous course of the disease had to be awaited. In 2013, a laparoscopic cholecystectomy for symptomatic gallstones was performed. The patient's CESD had caused a Child-Pugh A/B and Lab-MELD 14 cirrhosis with esophageal varices (grade III), a solitary fundal varix, as well as hepatosplenomegaly with thrombocytopenia. In 2016, the patient was admitted with compensated cirrhosis and splenomegaly for a ligature of esophageal varices which was complicated by vomiting of blood followed by severe coagulopathy and hemorrhagic shock. The dried blood test showed reduced acid lipase (0.03 nmol/spot*3 hours; reference range 0.2-2) and beta-galactosidase (0.08 nmol/spot*21 hours; reference range 0.5-3.2). Then 15 days after the esophageal varices bleed, the patient died due to multiorgan failure as a sequelae of advanced liver disease. CONCLUSIONS LAL-D should be included in the differential diagnosis of lipid metabolism disorder, hepatomegaly, and non-alcoholic fatty liver disease with fibrosis or cirrhosis. Causal treatment with sebelipase alfa should be introduced even in patients who have LAL-D and many years of clinically mild symptoms of this disease to prevent the serious sequelae of cirrhosis or cardiovascular complications.
