Abstract
In patients with SCD, chronic liver damage is a common manifestation. More than 50% of SCD patients have elevated liver enzymes. Common underlying aetiologies include sickle cell hepatic crisis, viral hepatitis, sickle cell intrahepatic cholestasis and hepatic sequestration in the acute setting, and cholelithiasis and iron overload in the chronic setting. Autoimmune hepatitis (AIH) is a rare disease that appears to occur more commonly in the sickle cell disease (SCD) population than in the general population. There are many schools of thought as to why this is the case, including the phosphatidylserine hypothesis, the heme inflammatory hypothesis, the complement generation hypothesis, and the transfusion alloimmunization hypothesis. Due to the natural history of the two illnesses, SCD is almost always diagnosed first in cases of dual pathology. Symptoms such as jaundice, fatigue, and abdominal pain are common in SCD, as are abnormal liver function tests (LFTs). These abnormalities, attributed to the other more frequent liver involvements in SCD, can lead to delays in AIH diagnosis in this population. Corticosteroids, sometimes with other immunosuppressive agents, such as azathioprine, are the cornerstone of acute AIH treatment. However, corticosteroid use in the SCD population has been shown to carry an increased risk of vaso-occlusive crises, providing a treatment dilemma. The following is a review of AIH in the SCD population, where we explore the pathophysiology behind the association between the two disorders, discuss an approach to investigating abnormal LFTs in SCD, and examine treatment options in this population with co-existing diseases.

Abstract
Sickle cell disease (SCD) is an inherited disorder, which occurs due to a single gene mutation. It has multisystemic manifestations, affecting millions of people worldwide. The effect of SCD on joints and musculature can overlap with clinical features of autoimmune disease (AD). It is therefore difficult for clinical haematologists and physicians treating SCD patients to discriminate between these two conditions clinically. A delay in diagnosis leads to untreated symptoms and treatment differs considerably. An accurate knowledge of clinical findings and laboratory results of AD and SCD can help physicians avoid this. In the review that follows, we examine the existing literature on SCD and AD, and describe the features that may distinguish SCD and autoimmune disease such as systemic lupus erythematosus and rheumatoid arthritis. We aim to guide clinical haematologists and physicians towards a more rapid diagnosis of AD in sickle cell anaemia patients, by correct interpretation of the clinical assessment and commonly available diagnostics.

Abstract
Sickle hepatopathy is an umbrella term describing various pattern of liver injury seen in patients with sickle cell disease. The disease is not uncommon in India; in terms of prevalence, India is second only to Sub-Saharan Africa where sickle cell disease is most prevalent. Hepatic involvement in sickle cell disease is not uncommon. Liver disease may result from viral hepatitis and iron overload due to multiple transfusions of blood products or due to disease activity causing varying changes in vasculature. The clinical spectrum of disease ranges from ischemic injury due to sickling of red blood cells in hepatic sinusoids, pigment gall stones, and acute/chronic sequestration syndromes. The sequestration syndromes are usually episodic and self-limiting requiring conservative management such as antibiotics and intravenous fluids or packed red cell transfusions. However, rarely these episodes may present with coagulopathy and encephalopathy like acute liver failure, which are life-threatening, requiring exchange transfusions or even liver transplantation. However, evidence for their benefits, optimal indications, and threshold to start exchange transfusion is limited. Similarly, there is paucity of the literature regarding the end point of exchange transfusion in this scenario. Liver transplantation may also be beneficial in end-stage liver disease. Hydroxyurea, the antitumor agent, which is popularly used to prevent life-threatening complications such as acute chest syndrome or stroke in these patients, has been used only sparingly in hepatic sequestrations. The purpose of this review is to provide insights into epidemiology of sickle cell disease in India and pathogenesis and classification of hepatobiliary involvement in sickle cell disease. Finally, various management options including exchange transfusion, liver transplantation, and hydroxyurea in hepatic sequestration syndromes will be discussed in brief.

Abstract
The hepatic complications of sickle cell disease (SCD) are associated with increased morbidity and mortality in adults; children usually survive but may suffer significant sequelae. Few diagnostic tools differentiate the various hepatic manifestations of SCD. Why patients exhibit one hepatic pathology versus another is unclear. We report four pediatric patients with hemoglobin SS disease with diverse manifestations of acute hepatic involvement including acute sickle hepatic crisis, hepatic sequestration, sickle cell intrahepatic cholestasis, and a non-SCD cause of hepatopathy in a patient with viral hepatitis. These complications require a systematic approach to extensive evaluation and coordinated multidisciplinary care.

Abstract
BACKGROUND Patients with sickle cell disease (SCD) present a defective activation of the alternate complement pathway that increases the risk of infection and is thought to predispose to autoimmune disease (AID). However, coexisting AID and SCD is rarely reported, suggesting possible underdiagnosis due to an overlapping of the symptoms. STUDY DESIGN Among 603 patients with SCD followed between 1999 and June 2016, we retrospectively searched for patients with coexisting SCD and AID. RESULTS We identified 8 patients aged from 7 to 17 years diagnosed with AID; juvenile idiopathic arthritis (n = 3), systemic lupus erythematosus (n = 2), Sjögren's syndrome (n = 1) and autoimmune hepatitis (n = 2). The diagnosis of AID was often delayed due to similarities of the symptoms with those of SCD. Patients treated with steroids experienced multiple vaso-occlusive crises and received prophylactic chronic blood transfusions when it was possible. Tolerance to other immunosuppressive and biological treatments, such as anti-TNF agents, was good. A remission of AID was achieved in 4 patients, without worsening the course of the SCD. One patient underwent a geno-identical hematopoietic stem cell transplantation that cured both diseases. Another one underwent a successful liver transplantation. CONCLUSION Coexistence of AID and SCD generates diagnostic and therapeutic challenges. Early diagnosis of AID is important to define the best treatment, which may include targeted biological therapy.

Abstract
OBJECTIVE To assess the incidence, clinical features, and outcome of autoimmune liver disease (AILD) in patients with sickle cell disease (SCD). STUDY DESIGN Single center retrospective review of patients with SCD with AILD referred between 1999 and 2015. RESULTS Thirteen of 77 (17%) patients with SCD with hepatic dysfunction were diagnosed with AILD (median age 11, range, 3.4-16 years) with a female preponderance (77%). Acute hepatitis and insidious onset were the commonest presentations. Two patients (15%) presented with acute liver failure. In 2 patients (15%), parvovirus B19-induced transient red cell aplasia preceded the diagnosis of AILD. All patients were positive for antinuclear and/or smooth muscle autoantibodies. Six of 12 patients (50%) had cholangiopathy on cholangiogram suggesting autoimmune sclerosing cholangitis (ASC). Liver biopsy, performed in 11 patients without complications, showed interface hepatitis in 90%. Patients with AILD were treated with standard immunosuppression. After a median follow-up of 3.8 years (range, 0.2-14.3), 10 patients are alive (1 was transplanted 6.4 years after diagnosis); 2 are lost to follow-up; 1 died of subdural hemorrhage before starting treatment for AILD. Five (42%) achieved full and 4 (33%) partial biochemical remission. Ulcerative colitis, present in 4 patients (2 male patients, 3 with ASC) was diagnosed in 2 patients before and in 2 patients after the diagnosis of AILD. CONCLUSIONS AILD is not uncommon in patients with SCD, affecting mainly female patients and responding satisfactorily to immunosuppressive treatment. Liver biopsy is helpful in confirming the diagnosis and can be safely performed in the absence of acute vaso-occlusive sickling episodes. Ulcerative colitis is common in the presence of ASC.

Abstract
The sickle hemoglobin is an abnormal hemoglobin due to point mutation (GAG → GTG) in exon 1 of the β globin gene resulting in the substitution of glutamic acid by valine at position 6 of the β globin polypeptide chain. Although the molecular lesion is a single-point mutation, the sickle gene is pleiotropic in nature causing multiple phenotypic expressions that constitute the various complications of sickle cell disease in general and sickle cell anemia in particular. The disease itself is chronic in nature but many of its complications are acute such as the recurrent acute painful crises (its hallmark), acute chest syndrome, and priapism. These complications vary considerably among patients, in the same patient with time, among countries and with age and sex. To date, there is no well-established consensus among providers on the management of the complications of sickle cell disease due in part to lack of evidence and in part to differences in the experience of providers. It is the aim of this paper to review available current approaches to manage the major complications of sickle cell disease. We hope that this will establish another preliminary forum among providers that may eventually lead the way to better outcomes.

Abstract
Autoimmune hepatitis (AIH) is thought to be a primary liver disease, occurring in the absence of any known etiology. We present three unusual cases of new-onset AIH in young female patients with longstanding preexisting liver disease (Alagille's syndrome, cystic fibrosis liver disease and sickle cell hepatopathy). All patients developed an insidious onset of abdominal pain, fatigue, jaundice and hepatitis after many years of their primary diagnosis and had negative serology for hepatitis A, B, C, cytomegalovirus and Epstein-Barr virus. The occurrence of AIH in these patients may be due to a complex interaction between the underlying liver disease, chronic medication use and genetic predisposition resulting in altered immunoregulatory mechanisms.

Abstract
Background Hepatic lesions in sickle cell disease were studied essentially in autopsy specimens. We investigated chronic hepatopathy in living adults with sickle cell disease and report the clinical, biochemical, and hepatic histological findings in these patients. Methods A total of 170 adult patients with sickle cell syndrome were prospectively investigated. Clinical and laboratory investigation including liver function tests, serological tests for viral hepatitis, autoimmune hepatitis, and abdominal ultrasonography were performed in all of the patients. Liver biopsies were studied from 27 patients. Results There was clinical evidence of jaundice in 123 (72.4%) patients, 118 (69.4%) patients had palpable liver, and 69% percent of the patients had elevated enzymes. Serological tests demonstrated the presence of hepatitis B infection in 18 (10.6%) patients and hepatitis C infection in 39 (23%) patients, serological markers for autoimmune hepatitis were positive in two female patients, one diagnosed chronic intrahepatic cholestasis. All 27 biopsies presented some degree of sickling hepatopathy. Moderate or marked liver siderosis was associated with the number of transfusions. Conclusions The clinical spectrum of sickle cell disease ranges from mild liver function test abnormalities to significant hepatic abnormalities with marked hyperbilirubinemia. Multiple factors may contribute to the etiology of the liver disease, including ischemia, transfusion related viral hepatitis, iron overload, and gallstones.

Abstract
Secondary sclerosing cholangitis (SSC) is a disease that is morphologically similar to primary sclerosing cholangitis (PSC) but that originates from a known pathological process. Its clinical and cholangiographic features may mimic PSC, yet its natural history may be more favorable if recognition is prompt and appropriate therapy is introduced. Thus, the diagnosis of PSC requires the exclusion of secondary causes of sclerosing cholangitis and recognition of associated conditions that may potentially imitate its classic cholangiographic features. Well-described causes of SSC include intraductal stone disease, surgical or blunt abdominal trauma, intra-arterial chemotherapy, and recurrent pancreatitis. However, a wide variety of other associations have been reported recently, including autoimmune pancreatitis, portal biliopathy, eosinophillic and/or mast cell cholangitis, hepatic inflammatory pseudotumor, recurrent pyogenic cholangitis, primary immune deficiency, and AIDS-related cholangiopathy. This article offers a comprehensive review of SSC.

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
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
Autoimmune hepatitis (AIH) remains an enigmatic condition that affects children of all ages. Although much knowledge has emerged over the past four decades regarding autoimmune diseases, the lack of a spontaneous animal model has hindered a more complete understanding of the pathophysiology of AIH. Serum autoimmune markers, combined with biochemical and histologic evidence of hepatocellular injury and absent other diagnostic considerations, are necessary to diagnose AIH. The clinical spectrum ranges from asymptomatic elevation of aminotransferase levels to acute liver failure. Patients with AIH type 1 are more likely to be older and have cirrhosis at the time of diagnosis, whereas those with AIH type 2 may have a more fulminant course and require life-long immunosuppressant medications. Overlap syndromes occur in children but are rare. Treatment with prednisone and azathioprine, alone or in combination, reverses the clinical course and improves biochemical abnormalities. Should liver transplantation be necessary, autoimmune injury may recur in the allograft.

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.
