Abstract
Hepatitis-associated aplastic anemia (HAAA) is a variant of acquired aplastic anemia and characterized by bone marrow failure that follows the development of acute hepatitis. We herein report a rare case of HAAA with rapid progression of liver fibrosis due to repeated hepatitis. A pathological examination of liver specimens revealed liver fibrosis progression over a short period. Immunosuppressive therapy with cyclosporine effectively cured both the pancytopenia and hepatitis. Our case suggests that the pathological examination of the liver tissue is useful for determining a treatment plan and that immunosuppressive therapy is a promising treatment for both aplastic anemia and persistent hepatitis.

Abstract
Background Precursor B-cell acute lymphoblastic leukemia accounts for 2% of all lymphoid neoplasms in the United States and occurs most frequently in childhood, but can also occur in adults with a median age of 39 years. It is more commonly seen in males and in Caucasians. Case Report We present a case of a 51-year-old Caucasian female with the development of precursor B-cell acute lymphoblastic leukemia after suffering acute hepatitis A 4 weeks prior to her diagnosis. She presented with malaise for a month without spontaneous bruising/bleeding, infections, or B-symptoms, such as fevers, night sweats, or unintentional weight loss. Conclusion Nonspecific viral transformation of bone marrow has been discussed in the literature, but we specifically describe hepatitis A-induced adult-onset precursor B-cell acute lymphoblastic leukemia, which is the first reported case in the literature.

Abstract
A 12-year-old Japanese boy suffered from severe acute hepatitis and pancytopenia. The patient underwent successful bone marrow transplantation from an HLA-identical sister. Torque teno virus (TTV) DNA of genotype 1a and IgM-class antibody against the virus were detected in sera at the onset of hepatitis. TTV/1a DNA and anti-TTV/1a IgM antibody levels were undetectable on the 16th and 46th days after the onset of illness, respectively. Anti-TTV/1a IgG antibody was positive throughout the observation period. Sequential viral load and anti-TTV/1a IgM antibody suggested a primary infection of TTV/1a. Genomic sequence of the virus coincided with that of the original strain first isolated from human. TTV DNA was quantified at 130 copies in 10(5) bone marrow mononuclear cells, which suggested that infection of hematopoietic cells might be the cause of aplasia. This is the first report of TTV hepatitis-associated aplastic anemia assessed by the anti-TTV antibodies and viral load in peripheral blood and bone marrow.

Abstract
BACKGROUND Hepatitis-associated aplastic anaemia is a syndrome in which marrow failure follows the development of hepatitis. AIM To review systematically the aetiology, immunopathogenesis, clinical presentation, diagnosis and treatment of hepatitis-associated aplastic anaemia. METHODS Literature searches were undertaken on the MEDLINE electronic database up to December 2008. Twenty-four relevant studies were identified. The clinical and laboratory characteristics of the patients were analysed and reviewed. RESULTS Hepatitis-associated aplastic anemia is a variant of acquired aplastic anemia in which an episode of hepatitis precedes the onset of aplastic anemia. The hepatitis may be acute and severe, even fulminant; it may be self-limiting or chronic. The pathology is often not attributable to a recognized cause of viral hepatitis. The syndrome occurs in 28 percent of young adults after liver transplantation for non-A, non-B, non-C hepatitis. Several features of the syndrome suggest that the marrow aplasia is mediated by immunological mechanisms, possibly mediated by gamma interferon or the cytokine cascade. Survival of patients treated with hematopoietic cell transplantation has been 82%, and the response rate to immunosuppressive therapy 70%. CONCLUSIONS Hepatitis-associated bone marrow aplasia is mediated by immunological mechanisms. Treatment options include hematopoietic cell transplantation and immunosuppressive therapy.

Abstract
Hepatitis A can be a serious disease and represents a substantial health and economic burden. In recent years, a decline in the number of cases of hepatitis A has been observed, which has been attributed in part to the implementation of vaccination policies in states with high disease incidence. In May 2006, the Advisory Committee on Immunization Practices published updated recommendations to include routine hepatitis A vaccination for all children beginning at 12 to 23 months of age. In this review, information on hepatitis A disease burden is presented with a discussion on the new recommendations and implementation of hepatitis A vaccination.

Abstract
BACKGROUND AND AIM The purpose of the present study was to investigate the influence of viral load on disease severity and analyze the possible relationship of the load of hepatitis A virus (HAV) with disease severity and laboratory findings. METHODS Fifty-eight patients diagnosed with acute hepatitis A were used in the current study, of whom 12 patients progressed to severe acute hepatitis (s-AH) defined on the basis of a prothrombin time (PT) of <40% and 46 patients were diagnosed as having mild acute hepatitis (m-AH). The load of HAV was measured with real-time polymerase chain reaction. RESULTS Peak viral load showed a significant correlation with alanine aminotransferase (ALT) (r = 0.363, P = 0.0048) and PT levels (r = -0.330, P = 0.0110). In terms of disease severity, there was a significant correlation with ALT (r = 0.462, P = 0.0012) and PT levels (r = 0.400, P = 0.0059) in the m-AH group, but not in the s-AH group. A significant positive correlation of peak viral load with the C-reactive protein level (r = 0.270, P = 0.0400) and a significant negative correlation of peak viral load with the platelet count (r = -0.313, P = 0.0015) was also found. CONCLUSIONS The load of HAV was closely correlated with liver damage and disease severity in m-AH, but not in s-AH. The load of HAV was also closely associated with the increase in C-reactive protein level and enhancement of thrombocytopenia.

Abstract
To determine the clinical characteristics and outcome of patients with chronic hepatitis C virus (HCV) infection presenting severe autoimmune cytopenia unrelated to interferon alpha therapy, we analyzed characteristics and outcomes of 35 patients with HCV (16 from our departments and 19 from the literature). We considered active autoimmune hemolytic anemia (AHA) as a decrease of at least 2 g/dL in hemoglobin levels, an increase of at least 0.6 mg/dL in the serum unconjugated bilirubin level, a reticulocyte count >5%, and a positive direct Coombs test. Severe neutropenia was defined as a neutrophil count <0.5 x 10(9)/L, and severe thrombocytopenia as a platelet count <30 x 10(9)/L. We identified the following cytopenias: AHA (17 cases), severe thrombocytopenia (16 cases), aplastic anemia (2 cases), severe neutropenia (1 case), refractory sideroblastic anemia (1 case), and pure red cell aplasia (1 case). Three patients simultaneously presented 2 types of severe cytopenias. Twenty-seven patients (77%) were female and 8 (23%) male, with a mean age at diagnosis of cytopenia of 51.7 years (range, 18-84 yr). Immunologic markers were detected in 19 (68%) of 28 patients, the most frequent being hypocomplementemia in 16 (57%), cryoglobulins in 15 (54%), antinuclear antibodies in 12 (43%), and rheumatoid factor in 5 (18%). Other associated processes were autoimmune diseases in 14 (50%) of 28 and human immunodeficiency virus (HIV) coinfection in 3 (9%) of 32. We found clinical and immunologic differences between HCV patients with AHA and those with severe thrombocytopenia. Patients with HCV-related AHA showed a higher prevalence of associated autoimmune diseases (71%), cryoglobulins (67%), and cirrhosis (59%). All had a good response to corticosteroids, but a poor prognosis (47% mortality). In contrast, patients with HCV-related severe thrombocytopenia had a lower prevalence of associated autoimmune diseases (11%), a poorer response to corticosteroids (55%), and lower mortality (6%), with HIV/HBV coinfections in some patients. The 35 cases presented demonstrate that different types of immune-mediated cytopenias may be severe and clinically significant in patients with HCV infection. Hemolytic anemia and severe thrombocytopenia were the most frequent cytopenias observed. Most patients responded well to corticosteroids, although a higher rate of mortality was observed in those with liver cirrhosis.

Abstract
To analyze the pathogenetic mechanism of hematopoietic dysregulation associated with hepatitis A virus (HAV) infections, we studied the influence of HAV on monocyte (MO)-to-macrophage (MAC) maturation in vitro. Exposure of peripheral blood-derived mononuclear cells (MNC) to HAV led to diminished adherence of MO to plastic. Furthermore, HAV inhibited the ability of peripheral blood MO to differentiate toward MAC. Freshly isolated and 14-day-old MO cultures demonstrated reduced differentiation and decreased phagocytic capacity after challenge with HAV. Viral replication in MO/MAC cultures was confirmed by titration of infectious virus. We also determined the influence of HAV on the MO/MAC population in human long-term bone marrow cultures (LTBMCs). Inoculation of bone marrow MNC with HAV suppressed the establishment of an adherent stromal layer containing a reduced number of MAC. Furthermore, increased MO numbers in the nonadherent fraction of HAV-challenged LTBMCs are indicative of the disturbance of MO adherence. These findings suggest that HAV infection leads to a disorder of the mononuclear phagocytic system which may contribute to functional abnormalities of the bone marrow stroma.

Abstract
The hepatitis A virus (HAV), a picornavirus, is a common cause of hepatitis worldwide. Spread of infection is generally person to person or by oral intake after fecal contamination of skin or mucous membranes; less commonly, there is fecal contamination of food or water. Hepatitis A is endemic in developing countries, and most residents are exposed in childhood. In contrast, the adult population in developed countries demonstrates falling rates of exposure with improvements in hygiene and sanitation. The export of food that cannot be sterilized, from countries of high endemicity to areas with low rates of infection, is a potentially important source of infection. After ingestion and uptake from the gastrointestinal tract, the virus replicates in the liver and is excreted into the bile. Cellular immune responses to the virus lead to destruction of infected hepatocytes with consequent development of symptoms and signs of disease. Humoral immune responses are the basis for diagnostic serologic assays. Acute HAV infection is clinically indistinguishable from other causes of acute viral hepatitis. In young children the disease is often asymptomatic, whereas in older children and adults there may be a range of clinical manifestations from mild, anicteric infection to fulminant hepatic failure. Clinical variants include prolonged, relapsing, and cholestatic forms. Management of the acute illness is supportive, and complete recovery without sequelae is the usual outcome. Research efforts during World War II led to the development of passive immunoprophylaxis. Pooled immune serum globulin is efficacious in the prevention and attenuation of disease in exposed individuals. More recently, active immunoprophylaxis by vaccination has been accomplished. Future eradication of this disease can now be contemplated.

Abstract
Hepatitis-associated aplastic anemia (HAAA) is an uncommon disorder that usually is not due to hepatitis A or B virus infection. Hepatitis C virus (HCV) seropositivity is infrequently observed in aplastic anemia (AA) patients who have not been extensively transfused. However, HCV seropositivity may not be detected until several weeks or months after viral infection and AA patients may exhibit defective humoral immunity. Therefore, we evaluated sera from AA patients for the presence of HCV viremia using a reverse transcriptase polymerase chain reaction (RT-PCR) based assay and several serologic assays for HCV antibodies. Serum samples from 90 AA patients who presented to the UCLA Medical Center between March 1984 and February 1990 were analyzed. Overall, 17 patients were found to have HCV viremia by RT-PCR assay, of whom 14 had a positive second-generation HCV enzyme immunoassay (EIA-2) and only 6 were EIA-1 reactive. The frequency of HCV viremia increased with the duration of time between diagnosis and sample procurement, and the number of blood products transfused prior to sampling (P = 0.026). No patient who received fewer than 20 U of blood products or who was sampled less than 20 days after diagnosis had a positive HCV RT-PCR result. Of four patients with hepatitis-associated AA (HAAA), one who was sampled 23 days after diagnosis had hepatitis C viremia and a reactive EIA-2 assay. Therefore, the high frequency of HCV viremia in this patient population is most likely due to transfusion with contaminated blood products prior to the introduction of routine blood donor screening for HCV.

Abstract
Hepatitis-associated aplastic anemia is rare in general, but occurs in up to 28% of patients receiving liver transplantation for fulminant non-A, non-B hepatitis. Cases are commonly young men with mild hepatitis but severe aplastic anemia. Although cases have been reported in association with hepatitis A, B, and C, most appear to be due to a non-A-B-C virus. We report two cases of acute hepatitis subsequently complicated by marrow hypoplasia in patients with acute parvovirus B19 infection. Hepatic manifestations of parvovirus B19 infection range from liver chemistry abnormalities to fulminant hepatic failure and aplastic anemia. Our cases demonstrate a less severe form of hepatitis-associated aplastic anemia, and together with other data, suggest that parvovirus B19 is at least one cause of hepatitis-associated aplastic anemia, and may be a heretofore underrecognized hepatotrophic virus.

Abstract
Aplastic anemia may result from several pathogenic mechanisms, the most common is idiopathic. The current definitive treatments for aplastic anemia are bone marrow transplantation (BMT) or immunosuppressive (IS) therapy. The benefits of each are comparable. However, certain subsets of patients derive superior benefit from one or the other. Bone marrow transplantation is the initial treatment of choice for young patients (< 20 years old). It results in the complete reconstitution of hematopoiesis, whereas autologous hematopoietic remissions after IS therapy are more susceptible to relapse. Survival rates after BMT, in patients between the ages of 20 and 40, are comparable to those reported for IS therapy. Better survival rates after BMT have been achieved with improved conditioning regimens and graft-versus-host disease prophylaxis. For patients older than 40, the treatment of choice is IS. Long-term complications of IS therapy include recurrence and development of clonal myeloid disorders. Long-term complications after BMT include graft-versus-host disease and secondary neoplasms. The IS regimen includes the combination of antithymocyte globulin and cyclosporin A. The addition of growth factor to the IS regimen seems promising; however, their use on their own is not recommended. Androgens have been shown to be inferior in the treatment of aplastic anemia. The role of BMT from an unrelated donor is being investigated.

Abstract
Aplastic anemia (AA) is a rare complication of viral hepatitis affecting mainly children or young adults. Most reported cases have been associated with community-acquired non-A, non-B hepatitis, but hepatitis A and B have also been implicated in a few patients. We report on a 43-year-old woman with severe AA, in association with acute hepatitis C virus (HCV) infection, diagnosed by detection of HCV RNA by the polymerase chain reaction technique. Her AA was successfully treated with anti-thymocyte globulin and cyclosporin A. The hepatitis C progressed to chronic disease but, despite a follow-up time of 2 years, the patient still has no detectable anti-HCV antibodies, as evaluated with a second-generation anti-HCV assay.

Abstract
BACKGROUND Bone marrow aplasia preceding acute lymphoblastic leukemia (ALL) is a rare condition that usually affects children. The ALL generally follows the recovery of normal blood counts and most commonly occurs within 6 months of the onset of aplasia. The case of a patient with severe aplastic anemia is reported in whom ALL developed 15 months after the initial diagnosis of aplastic anemia. A literature search found 23 cases of ALL after a period of aplasia or hypoplasia. This patient's disease, however, was different from all previously reported ones. The severe aplasia lasted 15 months before being followed by ALL. There was no recovery of blood counts before the onset of ALL. METHODS A review of the literature found 23 case reports in which aplasia or hypoplasia preceded ALL; these patients also had pancytopenia of the peripheral blood. Excluded from this review were patients whose bone marrow was hypoplastic, but who did not have pancytopenia because these did not have "aplastic anemia" as their initial disease. RESULTS Analysis of the reported patients showed that most were girls 10 years of age or younger. There was an overwhelming prevalence of fever, which in several instances, might have had an infectious cause. ALL most commonly occurred within 6 months of the aplasia and usually followed the recovery of normal blood counts. CONCLUSIONS Patients with ALL after a prolonged period of aplasia have several common characteristics including female sex, young age, and the prevalence of fever, often associated with an infectious illness. ALL usually follows the recovery of blood counts and occurs within 6 months of the onset of aplasia. The pathophysiology of this patient's disease(s) is still unclear. He could have had two unrelated disorders or a two-step leukemic process that followed a stem cell "insult." This patient had an antecedent hepatitis A infection 3 months before aplasia occurred. However, the authors were unable to identify with certainty any other event that might have caused additional bone marrow injury.

Abstract
Aplastic anaemia is a rare but serious complication of hepatitis, and hepatitis is an unusual cause of aplastic anaemia in children in the West. However, the relative frequencies of acquired aplastic anaemia in children in Taiwan, a hepatitis prevalent area, differ from those in the West, in the very high frequency of post-hepatitic aplastic anaemia (23.9% of all cases of aplastic anaemia). This may account for the higher incidence of aplastic anaemia in children in Taiwan. Although the prognosis of post-hepatitic severe aplastic anaemia was very poor, the present study using bone marrow transplantation, antithymocyte (or antilymphocyte) globulin, high-dose methylprednisolone and cyclosporin, etc., has improved the response rate and the survival.

Abstract
Some generalizations can be drawn from a review of virus-associated bone marrow failure. The story of B19 parvovirus illustrates that viral infection may be an occult cause of marrow failure. Although the epidemiology of transient aplastic crisis suggested a viral aetiology, the implication of a single virus was surprising; the sporadic appearance of chronic bone marrow failure in immunosuppressed persons has had none of the features of a viral illness. The incrimination of parvovirus in these cases required development of specific immunological and molecular assays. Human and animal retrovirus studies have shown that small changes in the virus genome can have dramatic effects on the biology of the infectious agent and its pathogenicity in infected hosts. In Epstein-Barr virus infection, the host's immune response may play a more important role in mediating disease than virus cytotoxicity. Finally, the association of aplastic anaemia with hepatitis may be underestimated because of the inability to diagnose virus infection without obvious liver disease. The true spectrum of bone marrow disease due to virus infection is not known.

Abstract
We describe two patients who developed aplastic anemia early in the course of non-A, non-B hepatitis. Spontaneous rapid recovery of bone marrow function occurred in both patients. Although early bone marrow transplantation has been recommended as the treatment of choice in hepatitis-associated aplastic anemia, these patients illustrate the need for a period of expectant observation before undertaking bone marrow transplantation in such patients.
