Abstract
Sickle cell intrahepatic cholestasis (SCIC) is a rare complication seen in sickle cell patients who present with sudden onset of RUQ pain, progressive hepatomegaly, mild elevation of transaminases, coagulopathy, and extreme hyperbilirubinemia. Early recognition of this entity is essential to avoid life-threatening complications. Diagnosis can be challenging given the overlap in clinical presentation with other conditions affecting the hepatobiliary biliary system in sickle cell anemia such as hepatitis, cholecystitis, and hepatic crisis. Treatment is currently limited to exchange transfusion. The authors present two patients with SCIC and cholelithiasis; the clinical picture of one is complicated by choledocholithiasis.

Abstract
We report a case of a 6-year-old girl of Afro-Caribbean origin, known to have sickle cell disease (SCD), with recurrent history of jaundice and abdominal pain. She was extensively investigated, including endoscopic retrograde cholangiopancreatography (ERCP), which revealed diffuse cholangiopathy of both extrahepatic and intrahepatic bile ducts. A pigtail stent was placed and balloon dilatation was performed for stricture of the extrahepatic duct. Since then, she remains well and asymptomatic. We suggest that cholangiopathy is the consequence of sickling in the end arteries of the biliary arterial tree.

Abstract
Very few cases of liver transplantation in patients with sickle cell disease have been reported in peer-reviewed literature. We reviewed the medical records of two patients with sickle cell disease that received liver transplantation at our institution. The first patient was a 27-year-old female who presented with encephalopathy and cholestatic jaundice with a Hemoglobin S (HbS) level of 69.6%. She was diagnosed with acute sickle cell intrahepatic cholestasis. The second patient was a 26-year-old female with sclerosing cholangitis who presented with encephalopathy, bleeding, and cholestatic jaundice. Her HbS level was normal. Both patients underwent liver transplantation successfully but died in the postoperative period from multiorgan failure. We report a rare case of liver transplantation for acute sickle cell intrahepatic cholestasis and a novel case of transplantation in a patient with sickle cell disease and sclerosing cholangitis. Liver transplantation did not lead to a successful outcome in either case.

Abstract
BACKGROUND Cholelithiasis is very common in patients with sickle cell disease (SCD) and is responsible for recurrent attacks of abdominal pain. The ideal management, especially for children, remains controversial. The purpose of the present study was to evaluate the safety and outcome of mini-laparoscopic cholecystectomy (MLC) in young children under age of 10 years with SCD. METHODS A prospective study was carried out of 75 children with SCD under 10 years of age with recurrent abdominal pains seen between August 2001 and March 2004 at Armed Forces Hospital, Khamis Mushayt, Saudi Arabia, who were screened for cholelithiasis. Twelve (16%) of the 75 children were found to have gallstones. The mean age was 7.8 years (range 4-9 years). All 12 children underwent MLC. Anaemia was corrected preoperatively in all the patients. Operative time, intraoperative complications, hospital stay, and postoperative recurrent abdominal pain were recorded. RESULTS The mean operating time was 46.5 min (range: 35-65 min). Intraoperative cholangiogram failed in two children due to narrow cystic ducts. The mean hospital stay was 2.1 days (range: 2-4 days). No patient required intra-abdominal drain. The mean follow-up period was 13.4 months (range: 4-24 months). The only postoperative complication was deep jaundice 1 month postoperatively due to cholestasis, and this responded to medical treatment. None of the children had recurrent abdominal pain after MLC. CONCLUSION Mini-laparoscopic cholecystectomy is a safe surgical procedure for the management of cholelithiasis in children with SCD and leads to improvement in the quality of life by decreasing the frequency of recurrent abdominal pain.

Abstract
PURPOSE Homozygosity for the (AT)7 allele of uridine diphosphate glucuronosyl transferase 1A (UGT1A1) gene polymorphism is associated with increased bilirubin levels in sickle cell anemia (SCA). In the present study, in addition to UGT1A1 promoter genotype, serum bilirubin level was related to other genetic modifiers -beta(S)-globin gene haplotype, Hb F, co-inherited alpha-thal trait, age and gender. METHODS The patients were randomly selected from the sickle cell clinic, Medical College of Georgia. UGT1A1 promoter polymorphisms were determined using automated sequencing. Other investigations were with standard techniques. RESULTS There were 67 SCA patients (41 males and 26 females), aged 2-44 yr (mean of 20.6 +/- 10.7). Ten (14.9%) patients were homozygous for the (AT)6 UGT1A1 allele, 35 (52.2%) were heterozygous for (AT)6 and (AT)7 alleles while 22 (32.8%) were homozygous for (AT)7. Serum bilirubin was significantly higher in the homozygous (AT)7 group (3.7 +/- 1.5, 3.8 +/- 2.3 and 5.6 +/- 2.4 mg/dL, respectively). It was also significantly higher in males than females and in patients aged >10 yr. There was a significant negative linear correlation (r = -0.304, P = 0.016) of serum bilirubin with Hb F. The beta-globin haplotype and co-existing alpha-thal trait did not have any significant influence on serum bilirubin levels. Patients on hydroxyurea were older, had lower Hb F, but higher mean serum bilirubin. The latter also was signifcantly higher among those with UGT1A1 (AT)7 homozygosity. CONCLUSIONS Apart from UGT1A1 (AT)7 homozygosity, Hb F, age and gender are the other factors that significantly influence serum bilirubin level in SCA.

Abstract
BACKGROUND Standard diagnostic criteria and therapy are lacking for sickle cell hepatopathy, an uncommon complication of sickle cell disease. Here we propose diagnostic and therapeutic guidelines based on our experience and on reported cases. METHODS We defined sickle hepatopathy by a total serum bilirubin concentration >13 mg/dl not explained by severe acute hemolysis, viral hepatitis, extrahepatic obstruction, or hepatic sequestration. We reviewed the records of all children with sickle hepatopathy seen at our institution during the past 20 years and the reported cases from the literature. Patients were categorized into two groups based on whether hepatic dysfunction at presentation was mild (Group I) or severe (Group II). RESULTS Seven patients were identified from our institution and 37 patients from the literature. The 44 patients were evenly divided between the two groups. Group I patients had a significantly lower mean age (11.8 years vs. 24.5 years, P = 0.0001), maximum bilirubin level (36.2 mg/dl vs. 76.8 mg/dl, P = 0.0008), and frequency of treatment with exchange transfusions (P = 0.03). Overall, mortality was 4% in Group I and 64% in Group II (P = 0.0001). Gender and recurrence rate did not differ. Among Group II patients, only two of nine who received exchange transfusion died, whereas 12 of 13 who did not receive exchange transfusion died (P = 0.0015). CONCLUSIONS Sickle cell hepatopathy is an uncommon complication characterized by extreme hyperbilirubinemia and either mild or severe hepatic dysfunction. Children and adults can present with either form; however, adults have a higher frequency of the severe form. Exchange transfusion may be the only effective management for initial episodes of severe sickle cell hepatopathy.

Abstract
Sickle cell disease is characterized by chronic hemolytic anemia and vaso-occlusive painful crises. The vascular occlusion in sickle cell disease is a complex process and accounts for the majority of the clinical manifestation of the disease. Abdominal pain is an important component of vaso-occlusive painful crises. It often represents a substantial diagnostic challenge in this population of patients. These episodes are often attributed to micro-vessel occlusion and infarcts of mesentery and abdominal viscera. Abdominal pain due to sickle cell vaso-occlusive crisis is often indistinguishable from an acute intra-abdominal disease process such as acute cholecystitis, acute pancreatitis, hepatic infarction, ischemic colitis and acute appendicitis. In the majority of cases, however, no specific cause is identified and spontaneous resolution occurs. This chapter will focus on etiologies, pathophysiology and management of abdominal pain in patients with sickle cell disease.

Abstract
Pain in sickle cell anemia (SCA) is clinically managed with opioid analgesics. There are reports that SCA patients tolerate high doses of these drugs without adequate pain relief. The current study investigated the in vitro hepatic metabolism of opioids in mouse models of sickle cell anemia, with the hypothesis that higher dose requirements in SCA could be explained by an increased metabolism rate of opioids. Various rodent cytochrome P450 substrates, i.e., buprenorphine and codeine, and rodent uridine glucuronosyltransferase substrates, i.e., morphine, buprenorphine, and estradiol, were studied. The three groups used were: 1) control C57BL mice, 2) mice with the human alpha-globin and sickle beta-globin transgenes (SC), and 3) mice with the human alpha-globin and sickle beta-globin transgenes, and homozygous for the murine alpha-globin and heterozygous for the beta(major)-gene knockout (SCKO). In vitro hepatic microsomal incubations were carried out for each substrate, and data were fit to the Michaelis-Menten equation. Morphine formation had a higher V(max) in SCKO microsomes (0.4 +/- 0.009 nmol/min. mg; estimate +/- S.E.) than controls (0.25 +/- 0.007). Morphine-3-glucuronide formation had V(max) estimates of 18.9 +/- 0.6, 25.1 +/- 0.4, and 27.06 +/- 1.1 nmol/min. mg in control, SC, and SCKO microsomes, respectively. The control V(max) for estradiol-3-glucuronide formation was 2-fold greater than in SCKO microsomes. The control V(max) for estradiol 17-glucuronide formation was 3.4- and 2.2-fold greater than in SC and SCKO microsomes. Thus, in vitro metabolism of opioids is altered in SCA mouse models, which may lead to altered clearances of these drugs.

Abstract
Sickle cell anemia is characterized by the presence of dense dehydrated erythrocytes that have lost most of their K content. Due to the unique dependence of Hb S polymerization on intracellular Hb S concentration, preventing this dehydration should markedly reduce polymerization. The erythrocyte intermediate conductance Ca-activated K channel (hSK4 or KCNN4), first described by Gardos, has been shown to be a major pathway for sickle cell dehydration. Studies with the imidazole antimycotic clotrimazole have shown reduction of sickle cell dehydration in vivo in a small number of patients with sickle cell disease; dose-limiting gastrointestinal and liver toxicities were observed. Based on the chemical structure of clotrimazole metabolites, a novel Gardos channel inhibitor, ICA-17043, has been developed. It has shown substantial activity both in vitro and in vivo in transgenic sickle mice. ICA-17043 is currently in phase 2 human trials. Another potential therapeutic target is the K-Cl cotransport. When sickle erythrocytes are exposed to relatively acidic conditions, they undergo cell shrinkage via activation of this pathway. K-Cl cotransport can be blocked by increasing the abnormally low erythrocyte Mg content of sickle erythrocytes. Oral Mg supplementation has been shown to reduce sickle cell dehydration in vivo in transgenic sickle mice and in patients in two separate clinical trials. Oral Mg pidolate is being tested in clinical trials in homozygous sickle cell disease and in Hb S/HbC (SC) disease, either as a single agent or in combination with hydroxyurea. The ongoing trials will determine the clinical effectiveness of therapies aimed at preventing sickle erythrocyte dehydration.

Abstract
Hydroxyurea therapy reduces hemolysis and decreases serum bilirubin levels in children and adults with sickle cell anemia (SCA) and may therefore help prevent the development of cholelithiasis in this patient population. We recently reported that a promoter polymorphism in the uridine diphosphoglucuronate glucuronosyltransferase 1A (UGT1A) gene affects steady-state bilirubin levels and the incidence of gallstones in children with SCA. We have now analyzed the influence of the UGT1A genotype on the therapeutic response to hydroxyurea. A large cohort of children with SCA taking hydroxyurea therapy at the maximum tolerated dose demonstrated significant reductions in hemolysis independent of UGT1A promoter polymorphism genotype, but the hydroxyurea-related decreases in serum bilirubin levels were significantly different. Children with the wild-type 6/6 UGT1A genotype demonstrated normalized bilirubin levels with hydroxyurea therapy, but children with the heterozygous 6/7 or abnormal 7/7 genotypes did not. Children with the abnormal 7/7 genotype, which confers the phenotype of Gilbert syndrome, had bilirubin levels greater than 3 mg/dL despite full-dose hydroxyurea therapy. These data indicate the UGT1A promoter polymorphism is a powerful nonglobin genetic modifier in SCA that influences serum bilirubin both at baseline and on hydroxyurea therapy. UGT1A promoter polymorphisms may therefore influence the ability of hydroxyurea to prevent gallstone formation in patients with SCA.

Abstract
The spectrum of renal disease in patients with liver disease is expanding. The recognition of renal complications of liver diseases is essential in the management of these patients. As liver transplantation is a treatment option for many patients with chronic liver disease, the presence of renal complications impacts the decision regarding transplantation and influences the course of these patients after transplantation, especially with regard to the use of immunosuppressive therapy. The involvement of the liver and kidney in systemic conditions is common and adds to the morbidity and mortality of patients.

Abstract
Many types of hemolytic anemia may be associated with liver disease. Liver injury can be caused by the adherence of deformed or hemolyzed erythrocyses to hepatic vascular endothelium. Adhesion of large numbers of hemolyzed red blood cells to hepatic macrophages, or occlusion of hepatic sinusoids by fragmented red cells, can also result in injury of the liver. Thrombosis of the hepatic or portal vein is associated with some types of hemolytic anemia, and can cause severe liner injury. These are some examples of hepatic injury that can be caused by hemolytic anemias. This article discusses some aspects of liver disease that is associated with sickle cell anemia, paroxysmal nocturnal hemoglobinuria, glucose-6-phosphate dehydrogenase deficiency, hereditary spherocytosis, and HELLP syndrome.

Abstract
OBJECTIVE Sickle cell disease is a relatively common disease seen predominantly in the African-American population with numerous important sequelae that require critical care management. We report a patient who presented with intrahepatic cholestasis, a rare and potentially lethal complication of sickle cell disease. DESIGN Individual case report and review of the literature. SETTING Medical intensive care unit of a tertiary care hospital. PATIENT A 37-yr-old African-American male, with known sickle cell disease, who developed fulminant hepatic failure with subsequent extreme hyperbilirubinemia, coagulopathy, and pericardial tamponade. Additional organ dysfunction included renal insufficiency, respiratory failure, and cardiac dysrhythmias. INTERVENTIONS The patient underwent serial measurements of complete blood count, hepatic profile, coagulation profiles, and hemoglobin electrophoresis. The patient received exchange transfusion, and his hemoglobin S concentration gradually decreased. Coagulopathy and anemia were corrected with transfusion of fresh frozen plasma and packed red blood cells. Serum bilirubin and other hepatic variables gradually improved. Pericardial tamponade was suggested by right heart catheterization measurements and diagnosed by echocardiographic findings. The tamponade resolved after pericardiocentesis and was managed by drainage through the pericardial catheter. Pulmonary, renal, and cardiac sequelae resolved with intensive supportive care that included intubation, mechanical ventilation, pulmonary artery catheterization, continuous renal replacement therapy, and permanent cardiac pacemaker. The patient was discharged home on hospital day 23 and has not required further hospitalization. CONCLUSION Sickle cell intrahepatic cholestasis, a potentially fatal complication of sickle cell disease, can present with abdominal pain, acute hepatomegaly, coagulopathy, hyperbilirubinemia, and fulminant hepatic failure. Prompt recognition and early intervention with exchange transfusion and intensive supportive care of multiple organ dysfunction can result in a favorable outcome.

Abstract
BACKGROUND Patients presenting sickle cell disease may develop different types of hepatic complications. Intrahepatic cholestasis is a potentially fatal complication of the disease, and sometimes the only possible solution is transplantation. Postoperative transfusion management has not yet been well established. In this report, we describe the transfusional program of a patient presenting sickle cell disease and intrahepatic cholestasis who underwent liver transplantation 2 years ago. METHODS Data were obtained from the chart and the blood bank records. RESULTS The liver transplantation was performed successfully. Despite mild allograft dysfunction 3 months after surgery, secondary to intrahepatic sickling, the patient has been doing well with the transfusional management adopted (sickle-cell hemoglobin <20%). CONCLUSION Sickle cell disease should not be a criterion for exclusion from liver transplantation. Regular transfusion with monitoring of sickle-cell hemoglobin is a very important measure to minimize the risk of intrahepatic sickling and possible rejection.

Abstract
We investigated the prevalence of positive viral hepatitis titres in sickle cell disease (SCD) and the relationship of abnormal liver function tests (LFTs) to transfusions and ferritin levels. Charts from 141 patients with SCD were reviewed and recent laboratory data on serum ferritin, hepatitis serology, units of packed red blood cells transfused and LFTs were collected. Hepatitis B core antibodies were positive in 14% of patients (12/86) and Hepatitis C viral antibody titres were positive in 16.5% (15/91). There was a relationship of positive serologies to transfusion for hepatitis C virus (HCV), but not for hepatitis B virus (HBV). Hepatitis C antibody negative (HCVAb-) patients had fewer packed red blood cells (pRBC) transfused than Hepatitis C antibody positive (HCVAb+) (6.4 vs. 20.3, P=0.08). Patients with ferritins < 500 ng/ml compared to those with > 1000 ng/ml also showed a difference in units transfused (P < 0.003). Steady state LFTs, with the exception of alkaline phosphatase, had no relationship to serum ferritin or hepatitis serologies. Males were twice as likely to have positive serology as females but more females had elevated ferritin levels. Paired analysis of LFTs in steady state and crisis failed to demonstrate deterioration during crisis. We conclude that: (1) there is a relationship of positive Hepatitis C serology, but not Hepatitis B serology, to transfusion; (2) ferritin levels correlate with transfusion number but not with LFTs; (3) in our population, LFTs in SCD are usually normal and do not increase in vaso-occlusive crises.

Abstract
PURPOSE Genetic mutations in the uridine diphosphate (UDP)-glucuronosyltransferase 1A (UGT1A) enzyme promoter have been associated with unconjugated hyperbilirubinemia and Gilbert syndrome. The effects of UGT1A promoter polymorphisms on serum bilirubin levels and symptomatic gallstone formation were studied in a cohort of children with sickle cell anemia (SCA). METHODS The UGT1A promoter genotype was deterrmined for 115 consecutive children with SCA. Steady-state laboratory parameters and previous cholecystectomy for symptomatic gallstones were recorded retrospectively, then analyzed according to UGT1A genotype. RESULTS Children with SCA had a lower frequency of the normal (TA)6 UGT1A promoter allele (0.413) than the abnormal (TA)7 allele (0.461). A previously described shorter (TA)5 allele (frequency 0.074) and longer (TA)8 allele (frequency 0.052) were also observed. Children with the 7/7 UGT1A genotype had a significantly higher mean bilirubin level (5.8 +/- 3.1 mg/dL) than those with the 6/6 (2.4 +/- 0.8 mg/dL) or 6/7 genotype (3.0 +/- 1.1 mg/dL; P < 0.001 by analysis of variance). Patients with the 7/7 genotype were more likely to have previous cholecystectomy (87.5%) than those with the 6/6 (35.7%) or the 6/7 genotype (36.1%; P = 0.002 by chi2). CONCLUSIONS Genetic variation in the UGT1A promoter significantly influences serum bilirubin levels and the development of symptomatic cholelithiasis in children with SCA. The UGT1A promoter polymorphisms represent an important nonglobin genetic modifier of clinical disease expression in SCA.

Abstract
BACKGROUND Chronic hemolysis predisposes adults with sickle cell disease (SCD) to the formation of bilirubinate cholelithiasis. METHODS To study the impact of laparoscopic cholecystectomy (LC) on this groups, we reviewed our records of all patients with SCD and cholelithiasis treated electively from 1991 to 1999. During that period, 13 consecutive patients with SCD underwent elective LC for symptomatic cholelithiasis. Nine patients (69.2%) were managed with a preoperative transfusion regimen to achieve a hemoglobin value of >/=10 g/dl, independent of hemoglobin S percentage. Five patients who presented with jaundice were referred for preoperative endoscopic retrograde cholangiopancreatography (ERCP), which identified choledocholithiasis in two of them. Three other patients underwent intraoperative cholangiography, which revealed common bile duct stones in one patient. RESULTS One patient developed pyrexia for 2 days. There were no vaso-occlusive crises or deaths. The mean hospital stay was 3.3 days. CONCLUSIONS LC has proven to be a safe and efficacious method for the treatment of symptomatic cholelithiasis in this high-risk population. Hematologists are now more willing to refer early, well-prepared patients with SCD and uncomplicated gallbladder disease for elective LC.

Abstract
The intracellular concentration of Hb S is an important determinant of the kinetic of polymer formation and cell sickling. A variable fraction of dense, dehydrated erythrocytes with high Hb S concentration is seen in the blood of patients with sickle cell disease; these dense cells play an important role in the pathophysiology of the vasoocclusive events of sickle cell disease, due to their higher tendency to polymerize and sickle. Sickle cell dehydration is due to loss of K+, Cl-, and water: the two major determinant pathways of dehydration of sickle erythrocytes are the Ca2+-activated K+ channel (IK1 or Gardos channel) and the K-Cl cotransport (KCC). Specific inhibitors of these pathways being tested in patients with sickle cell disease are Mg2+ pidolate, which inhibits KCC by increasing the sickle cell content of Mg2+, and clotrimazole and derivatives of clotrimazole metabolites, which specifically block the Gardos channel. An inhibitor of Cl- conductance has been shown to reduce dehydration in a transgenic mouse model of sickle cell disease but has not been tested in humans. If clinical efficacy and benefit are demonstrated, an inhibitor of cell dehydration could be used in patients as a single agent or in combination with existing therapies, such as hydroxyurea.

Abstract
BACKGROUND Sickle cell intrahepatic cholestasis is a potentially catastrophic complication of sickle cell anemia Once acute liver failure develops, transplantation is the only option. We describe a patient with sickle cell intrahepatic cholestasis who underwent liver transplantation. METHODS Data were obtained from the chart. Serial hemoglobin S levels were monitored, and measures were taken to maintain hemoglobin S <20% to prevent sickle cell crisis. RESULTS Although the allograft functioned well initially, the patient developed veno-occlusive disease and required repeat transplantation at 5 months after transplant. Histologic examination of the explant revealed occlusion of the terminal hepatic venules due to fibrosis and packed red cells. Repeat transplant was complicated by thrombosis of the intrahepatic portion of the hepatic artery, and sepsis. The patient died of sepsis after a third transplant. CONCLUSION Liver transplantation for sickle cell disease involving the liver may carry a high risk of graft loss due to vascular problems. Repeat transplantation may not be feasible if disease recurs.

Abstract
Hepatic dysfunction occurs commonly in children with sickle cell disease (SCD). Although the etiology is multifactorial, cholestasis is a prominent feature. Serum cholylglycine (CG) has been found to be a very sensitive indicator of cholestasis. Our objective was to determine whether CG levels are elevated in children with SCD and whether they are predictive of hepatic dysfunction. Blood samples were obtained from 97 children with SCD. Liver function tests were done and serum CG concentrations were measured. Patients were followed up for 2 years. Thirty-eight percent of the patients had an elevated CG level. During the 2 years of follow-up, 16% of the children with a previously elevated CG level developed abnormal liver function test results or required a cholecystectomy as compared with 13% with a previously normal CG level (p = 0.92). We conclude that although CG level was elevated in 38% of the patients with SCD, it did not appear to predict liver dysfunction during the ensuring 2 years.

Abstract
OBJECTIVE To evaluate hepatic drug metabolism, as determined by the formation of monoethylglycinexylidide (MEGX) after lidocaine injection and indocyanine green (ICG) clearance, in patients with sickle cell disease. STUDY DESIGN A case-control study including 19 patients with homozygous hemoglobin S, and 13 age- and sex-matched black control subjects. Serum MEGX concentration was measured after intravenous injection of 1 mg/kg (maximum 50 mg) lidocaine. ICG (0.5 mg/kg) was injected concomitantly and absorbance (805 nm) of serum was measured over time to determine its volume of distribution, serum half-life, and hepatic blood flow. RESULTS MEGX formation at 15 minutes was decreased in patients with sickle cell disease compared with formation in the control subjects (39.9 +/- 18.0 vs 65.6 +/- 50.0 micrograms/L, respectively, p < 0.02). The volume of distribution of ICG was increased in patients with sickle cell disease compared with that in the control subjects (0.21 +/- 0.09 vs 0.11 +/- 0.03 L/kg, p < 0.01). This partly accounts for the decreased MEGX formation. The ICG half-life was similar in both groups (3.8 +/- 1.5 vs 3.1 +/- 1.0 min). Hepatic blood flow, derived from ICG clearance, was increased in sickle cell patients compared with that of the control subjects (12.2 +/- 4.5 vs 8.1 +/- 2.1 ml/kg/min, p < 0.01). CONCLUSION Hepatic drug metabolism, as assessed by MEGX formation after lidocaine injection, is impaired in patients with sickle cell disease. This impairment may have clinical implications when using hepatically metabolized medications in patients with sickle cell disease.

Abstract
As surgery in sickle cell patients is associated with high morbidity, this study aims to establish the safety of minimally invasive surgery in this high-risk group. Over a four-year period, 71 sickle cell patients underwent laparoscopic cholecystectomy (LC) for cholelithiasis. Five patients had asymptomatic gallstones. Preoperative gastroscopy and endoscopic retrograde cholangiography were performed in 7 and 14 patients, respectively. Forty-two patients were given simple blood transfusions, while 13 received partial exchange transfusions. The mean operative time was 80 minutes and the conversion rate was 5.6%. There were 10 (14%) postoperative complications, the majority of which were respiratory and wound-related. One patient (1.4%) died as a result of postoperative vaso-occlusive crisis. The median hospital stay was 2.5 days. We believe that laparoscopic cholecystectomy is safe in patients with sickle cell hemoglobinopathy who are particularly at risk of developing pigmented gallstones. Therefore, the use of minimally invasive surgery is encouraged in any sickle cell patient undergoing operative intervention.

Abstract
PURPOSE To observe the safety and efficacy of hydroxyurea (HU), a drug that stimulates fetal hemoglobin (Hb F) production, in previously severely ill children with sickle cell disease. PATIENTS AND METHODS HU was given in an uncontrolled study to 35 children with sickle cell disease, aged from 3 to 20 years, suffering from frequent painful crises. Mean duration of treatment was 32 months (range: 12-59 months). RESULTS HU induced an increase in Hb F levels in all children out one; this increase was maximal after 9 months of treatment, was largely sustained thereafter, and was related to HU dose and inversely to patients' age. We also noted an apparent reduction in crisis, which occurred principally after 3 months of therapy and did not seem strictly correlated with the rise in Hb F level. No serious hematopoietic complication was observed. Growth curves and sexual development were not modified. CONCLUSION Our data support the efficacy of HU in reducing painful events in children with sickle cell disease. Short- and middle-term tolerances are good. Thus, we think that HU can be given to children affected by frequent and severe painful crises. We recommend, however, very cautious use of this drug, because its long-term effects in children are still unknown.

Abstract
PURPOSE We wish to alert clinicians to the possible association between Sickle cell anemia (SCA) and autoimmune liver disease (AIL). METHODS AIL was diagnosed by serologic, histologic and/or cholangiographic studies in patients with known SCA. RESULTS Three schoolaged children with SCA were investigated for increased levels of transaminases and/or worsening jaundice. All were diagnosed to have AIL. Two patients had autoimmune hepatitis and have responded to immunosuppressive therapy, and I had primary sclerosing cholangitis and is stable with therapy. CONCLUSIONS Autoimmune hepatitis and sclerosing cholangitis are rare liver disorders of childhood, but may occur with greater frequency in patients with SCA. Early diagnosis and treatment is essential to prevent progression to liver cirrhosis. This association may provide a clue to the etiology of AIL and warrants further investigation.

Abstract
A severe but unusual complication of sickle cell vaso-occlusive crisis is acute liver failure related to intrahepatic cholestasis. The outcome is usually fatal in adults. A case of reversible acute liver failure in a patient with s/beta+ thalassemia is reported. The patient was admitted to the intensive care unit because of major organ failure related to vascular occlusion phenomena. After blood-plasma transfusion and supportive therapy for acute liver failure, complete recovery was noted. A liver biopsy performed at the stage of recovery was compatible with intrahepatic cholestasis and sickling. Even though patients with s/beta+ thalassemia usually manifest milder symptoms, they rarely develop major organ failure such as acute liver failure.

Abstract
Nitric oxide (NO) acts as a nonadrenergic, noncholinergic inhibitor neurotransmitter that regulates sphincter of Oddi (SO) motor function. Hemoglobin blocks NO activity by binding it after it is synthesized. We hypothesized that recombinant human hemoglobin (rHb1.1) affects SO motor function by scavenging NO. Under anesthesia, 12 opossums underwent biliary tract manometry. Following a stabilization period, six animals were given rHb1.1 (0.28 g/kg over 30 min), while six received bovine albumin (0.28 g/kg over 30 min). Recordings were made during the infusion and for 3 hr after the infusion. In an in vitro preparation, force transducers were used to record spontaneous contractions at two sites along the sphincter segment. After a control period, rHb1.1 (0.1 mM) or cyanomethemoglobin (0.1 mM) was added to the tissue bath and recordings continued for another 2 hr. Recombinant human hemoglobin decreased the frequency of contractions, increased resting tone, and blocked the relaxation phase of contraction in vivo. It increased the baseline amplitude, the frequency, and the peak amplitudes of contractions in vitro. Albumin or cyanomethoglobin, which are unable to bind NO, had little effect on SO motor activity. We conclude that rHb1.1 may alter SO motor function by binding endogenous NO.

Abstract
We describe herein the case of a 57-year-old man with thalassemia who developed acute liver failure after undergoing endoscopic injection sclerotherapy (EIS) to control hemorrhage from a ruptured esophageal varix. The patient, who had been confirmed as having liver cirrhosis due to chronic hepatitis C with thalassemia in 1989, was admitted to our department to undergo EIS for esophageal varices, at which time his serum total bilirubin level was 5.5 mg/dl. As a small amount of hematemesis occurred just after a percutaneous transhepatic portography was performed, emergency EIS was carried out, following which the serum total bilirubin level markedly increased, mainly with a direct fraction, until it reached 70 mg/dl. The patient eventually died from acute liver failure with extreme hyperbilirubinemia on the 27th day after experiencing hematemesis despite all treatment. This unfortunate case demonstrates that sclerotherapy could be an inappropriate method of treatment for patients with hemolytic disease.

Abstract
BACKGROUND Preoperative transfusions are frequently given to prevent perioperative morbidity in patients with sickle cell anemia. There is no consensus, however, on the best regimen of transfusions for this purpose. METHODS We conducted a multicenter study to compare the rates of perioperative complications among patients randomly assigned to receive either an aggressive transfusion regimen designed to decrease the hemoglobin S level to less than 30 percent (group 1) or a conservative regimen designed to increase the hemoglobin level to 10 g per deciliter (group 2). RESULTS Patients undergoing a total of 604 operations were randomly assigned to group 1 or group 2. The severity of the disease, compliance with the protocol, and the types of operations were similar in the two groups. The preoperative hemoglobin level was 11 g per deciliter in group 1 and 10.6 g per deciliter in group 2. The preoperative value for hemoglobin S was 31 percent in group 1 and 59 percent in group 2. The most frequent operations were cholecystectomies (232), head and neck surgery (156), and orthopedic surgery (72). With the exception of transfusion-related complications, which occurred in 14 percent of the operations in group 1 and in 7 percent of those in group 2, the frequency of serious complications was similar in the two groups (31 percent in group 1 and 35 percent in group 2). The acute chest syndrome developed in 10 percent of both groups and resulted in two deaths in group 1. A history of pulmonary disease and a higher risk associated with surgery were significant predictors of the acute chest syndrome. CONCLUSIONS A conservative transfusion regimen was as effective as an aggressive regimen in preventing perioperative complications in patients with sickle cell anemia, and the conservative approach resulted in only half as many transfusion-associated complications.

Abstract
AIM To assess levels of some biochemical variables in sickle cell disease patients from eastern Saudi Arabia during steady state and in crises states, with a view to comparing biochemical and clinical manifestations of the disease with those in other geographical locations. METHODS Serum calcium, uric acid, total bilirubin, lactate dehydrogenase, hydroxybutyrate dehydrogenase, and haemoglobin were measured in 110 sickle cell patients when in steady state. The same variables were measured on 30 of the patients when they went into crisis. RESULTS Serum calcium tended to be lower in sickle cell patients than in healthy controls, while uric acid tended to be in the high normal range. Crises did not make any difference to serum calcium but they increased the uric acid level significantly. All the other variables measured were significantly abnormal and more so during crises. CONCLUSIONS Although the abnormal levels obtained for these biochemical variables in patients with sickle cell disease from eastern Saudi Arabia were similar to those from other geographical locations, there were noticeable differences in the severity of the abnormalities, which probably explains the differences in the clinical manifestations of the disease between geographical locations. Values of some of these variables could be adapted for use to monitor crises.

Abstract
To determine the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) markers among Bahraini children with hereditary haemolytic anaemias, a cross-sectional study was conducted at the paediatric outpatient clinic of Sulimaniya Medical Center in the State of Bahrain. A total of 242 patients with hereditary haemolytic anaemias were enrolled in the study: 171 (71%) with sickle cell syndromes, 59 (24%) with beta thalassaemia major and 12 (5%) with alpha thalassaemia. Among the 191 multi-transfused patients, 39 (20.5%) had one or more markers for HBV, 78 (40%) were seropositive for HCV antibody, and three (1.6%) were seropositive for HIV antibody. In contrast, none of the 51 non-transfusion group was seropositive for HBV and HIV antibodies but one patient was seropositive for HCV antibody. HBV, HCV and HIV infections therefore remain a major hazard for children with hereditary haemolytic anaemias, despite blood donor screening. More refined and sensitive tests which would detect infection in all stages of the disease are required. Hepatitis B vaccine should be given to all children with hereditary haemolytic anaemias.

Abstract
UNLABELLED Acute liver failure is unusual in sickle cell anaemia. We describe a child with homozygous sickle cell anaemia who developed acute liver disease of abrupt onset during an episode of limb pain. She presented with sudden onset of persistent vomiting, headache, lethargy, epistaxis, and painful liver enlargement. Laboratory investigations were indicative of cholestasis and severe liver failure with profound prolonged clotting times, hypofibrinogenaemia, elevated serum ammonia and lactic acidosis. The symptoms were promptly and completely reversed by two partial exchange transfusions. No evidence of viral infection was found. Cholelithiasis was ruled out by ultrasonography. The child recovered from what appeared to be massive hepatic sickling with no apparent sequelae. CONCLUSION Massive hepatic sickling should be considered in the differential diagnosis of a child with homozygous sickle cell disease who suddenly develops acute liver failure. Exchange transfusion should be promptly carried out so as to reverse ischaemic hepatic injury.

Abstract
The histology of a liver specimen from the autopsy of each of 58 sickle cell anaemia patients aged 3-45 years was examined. Sinusoidal distension (present in all specimens), haemosiderosis and erythrophagocytosis (56), portal triaditis (47), cholestasis (24), focal necrosis and fibrosis (23), and extra-medullary erythropoiesis (3) were observed. The livers from the older patients (30-45 years) showed severe haemosiderosis, chronic inflammation, pigment stones and fatty change.

Abstract
FHF is an uncommon but devastating condition affecting otherwise healthy persons which causes significant morbidity and mortality. The etiologic factor is most commonly viral infection, with drugs and metabolic disorders being relatively less common causes. Hopefully, newer diagnostic techniques such as PCR will increase our understanding of the causes and pathogenesis of this disorder. Medical management at the present time must focus on anticipating, preventing, and rapidly identifying and treating complications that may affect every major organ system. Encouraging research continues on the clinical application of hepatotrophic drugs and artificial liver support systems, both as potentially definitive therapies and as maintenance for patients awaiting transplantation. Consultation with physicians at a transplant center should be sought early in the course of the patient's hospitalization when OLT is being considered. Liver transplantation has dramatically changed the outlook for patients with FHF, with current survival rates in the 55% to 75% range. The continuing challenge for the transplant team is to allocate available donor organs to those patients who would not otherwise survive, but also to provide OLT in a timely fashion to ensure the best chance of post-transplantation recovery. Newer techniques such as heterotopic liver transplantation, reduced-size organ transplantation, and the utilization of living related donors may further improve the survival of these patients.

Abstract
A child with sickle cell anaemia developed a hepatic abscess, which was managed successfully by percutaneous drainage under ultrasound control. A history of attacks of pain dissimilar to usual vaso-occlusive crises should be treated with suspicion and investigated appropriately.

Abstract
Acute abdominal pain occurs frequently in patients with sickle cell anaemia (SCA), and presents a difficult diagnostic and management problem as the clinical presentation may mimic an acute surgical condition. Good clinical judgement and careful observation are necessary to avoid increased morbidity and mortality. Chronic recurrent upper abdominal pain is also a common problem and in many the cause is unknown. These patients usually respond to simple symptomatic therapy.

Abstract
Since 1973, 419 children (233 boys, 186 girls) with chronic haemolytic anaemia (mean age, 10.2 +/- 3.5 years) have been splenectomised. Fifty-three (12.6%) have also been cholecystectomised because of cholelithiasis. Between 1973 and 1982, cholecystectomy and splenectomy were performed at the same time in symptomatic patients. Later, between 1983 and 1987, cholecystectomy was also performed in clinically asymptomatic patients with positive sonographic findings. In the first period, 11 thalassaemic patients (45.8%) were cholecystectomised a short period after splenectomy (in two cases, only 2 and 3 weeks later). Between 1983 and 1987, when asymptomatic patients with cholelithiasis were screened by sonography, simultaneous cholecystectomy and splenectomy were performed in 13.6% of the patients with thalassaemia, in 41% of the patients with sickle cell or microdrepanocytic disease, and in 22.2% of the patients with spherocytosis. As there is a high incidence of asymptomatic cholelithiasis and hypersplenism in patients with chronic haemolytic anaemia, screening for gallstones should precede splenectomy. Simultaneous cholecystectomy should be performed in patients with cholelithiasis.

Abstract
The prevalence of gall stones was studied prospectively by abdominal ultrasound examination in 131 patients with sickle cell disease aged 10-65 years. Of 95 patients with homozygous sickle cell disease, 55 (58%) had gall stones or had had a cholecystectomy. Gall stones were present in four out of 24 (17%) patients with haemoglobin S + C disease and two out of 12 (17%) with haemoglobin S beta thalassaemia. The presence of gall stones was not related to sex, geographical origin, or haematological variables and was not associated with abnormal results of liver function tests. Symptoms typical of biliary colic were reported by 32 out of 47 adult patients with gall stones, and cholecystitis or cholestasis was diagnosed in 18. Cholecystectomy was performed in 29 patients with good relief of symptoms in most cases. Postoperative complications were common, occurring in 10 of the 28 patients who could be evaluated, but not generally serious; they were considerably lessened by a preoperative exchange transfusion that reduced the haemoglobin S concentration to below 40%. It is suggested that all patients with sickle cell disease should be screened for gall stones and that elective cholecystectomy should be performed in those with symptoms or complications.

Abstract
The spectrum of diseases seen in patients from certain 'tropical areas' requires that a physician be aware of some of the syndromes discussed here. A high index of suspicion for less usual causes of cirrhosis is imperative when evaluating such patients presenting with hepatocellular disease. The differential must be expanded and the work-up complete. Liver biopsy should be performed as early in the course of disease as is feasible and will often provide valuable diagnostic information. It will not only facilitate treatment but allow for needed clinical trials and may help to increase our understanding of the various disease processes.
