Abstract
We present a case of reactivation of chronic hepatitis B virus (HBV) infection by a steroid-producing adrenal tumour. The tumour caused a reactivation and subsequent flare of the patients' HBV. The adrenal tumour was treated with an adrenalectomy and as a consequence the patients' transaminitis and viral load fell rapidly without the need for any additional hepatitis B treatment. The role of hepatitis B and steroid priming is discussed and the possible immunological mechanisms that underpin this phenomenon.

Abstract
It is well known that immunosuppressive drugs or cancer chemotherapy can stimulate replication of hepatitis B virus (HBV) and precipitate severe flares of HBV infection. The risk of this syndrome of 'reactivation hepatitis B' is highest in haematopoietic stem cell or solid organ transplant recipients and in those undergoing chemotherapy for haematological malignancies; however, it has been described following almost any form of immunosuppressive treatment. Fortunately, it can be largely prevented by prophylactic therapy with oral anti-HBV nucleoside/nucleotide analogues. Importantly, chronic HBV infection is usually asymptomatic, and most patients at risk are likely to be unaware that they carry the infection. Thus, the key to avoiding this potentially fatal complication of immunosuppressive treatment is to ensure that all patients at risk of chronic HBV infection are screened for the disease before commencing immunosuppressive treatment or chemotherapy.

Abstract
Reactivation of hepatitis is one of the most serious complications of chemotherapy in lymphoma patients who are carriers of the hepatitis B virus (HBV). Glucocorticoids are linked to increased risk of HBV reactivation. This study seeks to clarify whether removal of glucocorticoids from chemotherapy regimens may decrease the risk of HBV reactivation. Eligible patients were seropositive for hepatitis B surface antigen (HBsAg) and had histologically proven non-Hodgkin's lymphomas for which intensive chemotherapy was indicated. Patients were randomized to receive either ACE (epirubicin, cyclophosphamide, and etoposide) or PACE (prednisolone + ACE). A total of 50 patients were enrolled, 25 each for the ACE and PACE arms. The cumulative incidence of HBV reactivation at 9 months after starting chemotherapy was 38% and 73% for ACE and PACE arm, respectively (P =.03). The degree of clinical hepatitis was significantly more severe in the PACE arm: 11 patients (44%) in the PACE and 3 patients (13%) in the ACE arm had ALT elevation more than 10-fold of normal (P =.025), and 7 patients (28%) in the PACE and 1 patient (4%) in the ACE arm had icteric hepatitis (P =.049). Complete remission of tumors occurred in 11 (46%) patients in the PACE and 8 (35%) patients in the ACE arm (P =.556). The estimated overall survival rate at 46 months was 68% in the PACE arm and 36% in the ACE arm, respectively (P =.18). In conclusion, steroid-free chemotherapy decreases the incidence and severity of HBV reactivation in HBsAg-positive lymphoma patients. However, further research is needed to evaluate whether steroid-free chemotherapy may confer a less satisfactory control of lymphoma.

Abstract
Chronic infection with the hepatitis B virus (HBV) affects 350 million people worldwide, or approximately 5% of the global population, and commonly results in cirrhosis and hepatocellular carcinoma. Until recently, the only available treatment was injectable interferon alpha and response rates were suboptimal. Moreover, this expensive and toxic therapy had little applicability in the endemic regions of the world, i.e., Asia and Africa. The realisation that orally available nucleoside and nucleotide agents may effectively control this infection opened a new era in the management of chronic hepatitis B. Oral lamivudine recently became approved for treatment of hepatitis B worldwide. It is free of significant toxicity, improves liver histology and rapidly diminishes HBV DNA levels; lamivudine is expected to become the first-line therapy of choice. Nevertheless, the consistent emergence of lamivudine-resistant variants mandates the need to develop additional therapeutic agents. Adefovir dipivoxil, a nucleotide, and entecavir, a nucleoside agent, are promising new drugs that might eventually be used in combination with lamivudine and therefore reduce the incidence of drug resistance. There is a critical need to advance the research of hepatitis B antiviral agents so that effective combination therapies can become widely available.

Abstract
Acute flares in chronic hepatitis B are common and may be caused by a number of identifiable and potentially treatable factors. The common link for many of these exacerbation episodes is a change in the immunologic response to hepatitis B virus (HBV), and this may have no identifiable cause or be triggered by an increase in viral replication or genotypic change. It is important to keep in mind the clinical situations in which patients are at increased risk of reactivated infection and secondary exacerbations. Reactivation is frequently induced by medical treatments such as cancer chemotherapy, antirejection drugs used in organ transplantation, and corticosteroids. The immunologic flares that often result from sudden withdrawal of these medications can be life-threatening unless recognized and treated promptly with antivirals, and there is increasing experience that preemptive antiviral treatment can diminish their occurrence and improve the outcome. The experience with lamivudine and other nucleoside analogues has increased our understanding of the molecular events behind hepatitis flares that occur when chronic hepatitis B is treated with drugs that potently inhibit HBV DNA polymerase. However, not all flares are explainable by events related to HBV infection alone. Depending on the population studied, as many as 20%-30% of flares may be caused by infection with other hepatotropic viruses, and this situation may inhibit HBV replication. Proper understanding of the etiology and effective treatment of acute flares in chronic hepatitis B requires an appreciation of high-risk clinical situations, assessment of HBV replication status, and testing for other viruses when appropriate.

Abstract
Immunosuppressive therapy increases levels of hepatitis C virus (HCV) RNA, and when combined with interferon, corticosteroids have been reported to variably improve or have no effect on sustained response rates. We conducted a randomized double-blind placebo-controlled trial in 39 patients with biopsy-proven chronic HCV infection and elevated alanine aminotransferase levels. Patients received either 6 weeks of a tapering dose of prednisone (60 ng, 40 mg, and 20 mg in 2-week intervals) or an identical placebo. All patients then received recombinant interferon alpha-2b, 3 million units three times a week for 24 weeks. Patients were then followed for a further 24 weeks. At the end of the study there was no significant difference in the sustained biochemical response rates between the two groups (4/20 vs. 3/19, p value was not significant). Prednisone-treated patients had a significant increase in HCV RNA from baseline during steroid treatment (400 +/- 60% increase vs. -280 +/- 140% decrease; p = 0.005). Two prednisone-treated patients were withdrawn from the study secondary to serious complications related to therapy. Prednisone priming before interferon alpha therapy in patients with chronic HCV infection does not improve the sustained response rate. This therapy was associated with an increase in viral burden and significant morbidity.

Abstract
Hepatitis B has been a major challenge within the field of transplantation over the past few decades. Due to aggressive recurrence post-transplant, patients with hepatitis B have been excluded from the benefits of both solid organ and bone marrow transplants. Progress has been made, however, through an improved understanding of the biology of hepatitis B and the development of new antiviral strategies that can reliably suppress the virus. Patients with hepatitis B are now candidates for transplantation in an increasing number of circumstances. Careful pre-transplant evaluation is mandatory, together with a tailored antiviral regimen depending on the replicative status of the virus and the organ being transplanted. Minimizing steroid dose following transplantation is an important part of the strategy to reduce the risk of viral reactivation. Lamivudine has been an important development and it has assumed an increasing role in the management of these patients. As additional antivirals are developed, increasingly effective drug combinations will prevent viral recurrence as well as the emergence of drug-resistant mutants, which plagues the use of single agents. It is a rapidly evolving field and there is every reason for continued optimism.

Abstract
Clinical and experimental studies have shown that T cell-mediated immune mechanisms are involved in the pathogenesis of hepatitis B virus (HBV) and hepatitis C virus infection. Immunosuppressants may impair T cell function and thereby reduce immune-mediated hepatocytolysis and virus clearance. In addition, corticosteroid may activate the glucocorticoid responsive element in the HBV genome to enhance HBV replication and gene expression. These combined effects result in an increase of viraemia in association with a decrease of serum aminotransferase and hepatic necroinflammation. In acute infection, use of immunosuppressants will increase the incidence of chronic evolution. In chronic infection, withdrawal of immunosuppressants will be followed by a clinical flare due to a rebound of immune attack to hepatocytes with increased viral load. This may lead to a subsequent decrease of the viraemia. Therefore, short-term use of immunosuppressant before antiviral therapy may be beneficial in the treatment of chronic viral hepatitis. However, the clinical rebound may be extremely severe and lead to hepatitis failure; thus, the patients should be monitored closely upon tapering and after the withdrawal of immunosuppressants. Long-term use of immunosuppressants in patients with hepatitis virus infection is usually deleterious, particularly in patients after organ transplantation. These findings suggest that clinicians should be cautious in the use of immunosuppressants in patients with hepatitis virus infection.

Abstract
BACKGROUND/METHODS In order to define the clinical significance of borderline levels of IgM anti-HBc in chronic hepatitis B patients, we followed up 89 untreated hepatitis B patients (19 HBeAg pos and 70 anti-HBe pos) for 1 year, with monthly monitoring of IgM anti-HBc using a highly sensitive quantitative microparticle enzyme immunoassay (IMx CORE-M, Abbott). As a control group we used 304 healthy subjects: 150 HBsAg negative and anti-HBc/anti-HBs positive, and 154 without markers of HBV infection. The statistical analysis performed by Receiver Operating Characteristic curve indicated the 100% sensitivity cut-off at 0.081 IMx index and 100% specificity cut-off at 0.358 IMx index. RESULTS We could define the range of a chronic hepatitis B "gray-zone" between 0.100 [80.6% specificity (95% CI, 76.2%-85%), 96.6% sensitivity (95% CI, 92.8%-100%)] and 0.200 [95.7% specificity (95% CI, 93.4%-98%) and 78.7% sensitivity (95% CI, 70.2%-87.2%)] of the IgM anti-HBc-IMx index. In fact, none of the chronic hepatitis B patients had IgM anti-HBc-IMx values persistently below 0.100 during the follow-up, whereas 57.3% had values persistently higher than 0.200. In 38.2%, IgM anti-HBc values occasionally fell within the "gray-zone" limits. In the remaining four patients (4.4%), the results overlapped the "gray-zone" values. CONCLUSIONS These results suggest that the use of a chronic hepatitis B "gray-zone" for values of quantitative IgM anti-HBc assays helps to distinguish "true healthy carriers" from asymptomatic chronic anti-HBe positive hepatitis B patients who have been shown to have temporary remissions of liver disease and frequently undetectable serum HBV-DNA.

Abstract
To analyse the incidence and risk factors of clinical rebound and hepatic decompensation during or upon withdrawal of prednisolone pretreatment before interferon (IFN) therapy, two series of Taiwanese patients with chronic viral hepatitis from two independent randomized controlled trails were compared. Group 1 included 41 patients with chronic hepatitis B who were pretreated with daily prednisolone (30 mg) for 3 weeks, 15 mg for 1 week and no prednisolone for 2 weeks prior to lymphoblastoid IFN therapy. Group 2 consisted of 59 patients with chronic hepatitis B who were pretreated with daily prednisolone (40 mg) for 2 weeks, 30 mg prednisolone for 2 weeks, 20 mg prednisolone for 2 weeks and no prednisolone for 2 weeks prior to INF alpha-2a therapy. Clinical rebound developed more frequently in group 2 (67.8%) than in group 1 patients (41.5%; P < 0.01). The peak serum transaminase levels of group 1 and 2 patients during clinical rebound were similar. Icteric and symptomatic clinical rebound occurred in four (one cirrhotic) group 2 patients. The incidence of hepatic decompensation was 3.4% in group 2 patients, or 5.0% in group 2 patients with clinical rebound. Patients pretreated with a higher dose (40 mg) of prednisolone (odds ratio 3.0; 95% CI 1.3-6.6; P < 0.01) and non-cirrhotic patients (odds ratio 6.2; 95% CI 1.2-32.1; P < 0.02) tended to suffer from clinical rebound more frequently. However, once clinical rebound develops in cirrhotic patients, the relative risk of decompensation is 16 times that of non-cirrhotic patients. These results suggest that clinicians should be cautious in prescribing a short course of corticosteroids for patients with chronic viral hepatitis, because hepatic decompensation might occur in Oriental people with or without cirrhosis.

Abstract
Fifty-six patients with biopsy-proven, chronic active hepatitis B were included in a multi-center, randomized trial comparing steroid withdrawal followed by 1.5 MU recombinant interferon alpha 2b (Intron) with placebo withdrawal followed by either 1.5 or 5 MU interferon. The patients were equally distributed between the treatment groups with respect to biochemical and histologic activity as well as with respect to DNA levels and quantitative liver function tests. One patient was lost to follow up. After 1 year of treatment, 10/18, 13/19 and 11/18 patients had lost hepatitis B virus DNA in the three groups, respectively (non-significant). Transaminase levels were normal in 27/34 of the responders but in only 4/21 of the non-responders (p < 0.0001). Both galactose elimination capacity and aminopyrine breath test improved significantly in responders, but either did not change (aminopyrine breath test) or deteriorated in non-responders (galactose elimination capacity). Biopsy score improved in both groups but this reached statistical significance only in responders. This effect was due to improvements in both inflammatory and fibrotic activity. Side effects included almost universally a flu-like syndrome, granulocytopenia (1), depression (3) and thyroid dysfunction (2). Two deaths occurred, one due to hepatocellular cancer, and the other to hepatorenal syndrome after spontaneous bacterial peritonitis. A severe cytolytic episode was observed in three patients in the steroid withdrawal group. We conclude that in patients with marked histologic activity, lower doses of interferon may be as effective as the standard dose of 5 MU.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The clinical significance of a semi-quantitative microparticle enzyme immunoassay (IMx Core-M, Abbott) was evaluated for detection of IgM-class antibodies against the hepatitis B core antigen (IgM anti-HBc) in 136 hepatitis B surface antigen (HBsAg) positive individuals (96 chronic HBV carriers, 20 patients with chronic HBV-HDV infections and 20 patients with acute hepatitis B) and 50 HBV-negative controls. Baseline and follow-up sera (4-11 samples) were analysed from 79 carriers with chronic hepatitis B, 44 of whom were treated with interferon. IMx indexes above 3,000 were found in 95% of the acute hepatitis B patients and above 0.300 in 91.5% of patients with ongoing chronic hepatitis B. IMx indexes between 0.200 and 0.300 were observed in (a) patients with recent HBeAg to anti-HBe seronconversion (6-12 months) and normal serum ALT levels, (b) patients immuno-tolerant to HBV infection and without liver disease despite high levels of viremia, and (c) patients with anti-HBe-positive chronic hepatitis B during 7-13-month intervals of asymptomatic carriage between episodes of disease reactivation. IMx indexes below 0.200 were detected in all HBV-negative individuals and healthy HBV carriers, in 14 (70%) of 20 chronic hepatitis D patients and in all but 1 of 22 interferon-treated patients with histological remission of liver disease, 5-12 months after clearance of viremia and normalization of serum ALT levels. In contrast, IMx indexes remained above 0.200 in all patients with hepatitis B reactivation.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Glucocorticoids have been shown to influence the severity of hepatitis B virus-related chronic hepatitis in human. However, very little is known about the effects of glucocorticoids on hepatitis B virus replication in vitro. In this report, we used a well-differentiated human hepatoma cell line, Hep3B, transfected with hepatitis B virus complementary DNA as a model to show that a glucocorticoid analog, dexamethasone, can directly stimulate the production of HBsAg and HBeAg. Elevation of 3.5-kb pregenomic RNA and all other viral RNAs in the transfected Hep3B cells after dexamethasone treatment supports the hypothesis that glucocorticoids directly stimulate hepatitis B virus gene expression in vitro. The concentration of dexamethasone for its half-maximal stimulatory activity toward HBsAg, HBeAg and all viral transcripts was approximately 10(-8) mol/L, close to the affinity of glucocorticoid receptors to [3H]-triamcinolone acetonide in Hep3B cells (approximately 10(-8) mol/L). Specific glucocorticoid antagonist RU38486 completely blocked dexamethasone-induced HBV gene expression, suggesting that the stimulatory effect of dexamethasone was mediated through specific glucocorticoid receptors.

Abstract
Forty-one hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV) DNA positive Chinese patients with chronic active hepatitis B were randomized to receive either prednisolone or placebo oral for 8 weeks. The prednisolone group received 60 mg daily for 2 weeks, 40 mg for 2 weeks, 20 mg for 2 weeks, 10 mg for 1 week and 5 mg for 1 week. In 18 patients receiving prednisolone, serum HBV DNA levels rose during the course of therapy, but dropped abruptly within 1 month of cessation of treatment. Conversely, their serum alanine aminotransferase (ALT) levels decreased during high doses of prednisolone therapy, and then became transiently elevated during the period of withdrawal of prednisolone. At 1 year from initial treatment, the serum HBV DNA and ALT levels were similar between the groups of patients treated with prednisolone or placebo. In the prednisolone treated group, 66.7% of patients became HBV DNA negative, 50% became HBeAg negative, and 33.3% seroconverted to antibody to HBeAg (anti-HBe). In the placebo treated group, 60.9% of patients became HBV DNA negative, 60.9% became HBeAg negative, and 56.5% seroconverted to anti-HBe. Hepatic decompensation was not noted in any of the prednisolone-treated patients. Thus, the effects of the withdrawal prednisolone therapy on serum ALT and HBV DNA levels was temporary, and no differences in serum viral markers or biochemical parameters of liver inflammation between these two groups were noted at the 1 year follow-up period.

Abstract
BACKGROUND AND METHODS Chronic hepatitis B is a common and often progressive liver disorder for which there is no accepted therapy. To assess the efficacy of treatment with interferon, we randomly assigned patients with chronic hepatitis B to one of the following regimens: prednisone for 6 weeks followed by 5 million units of recombinant interferon alfa-2b daily for 16 weeks; placebo followed by 5 million units of interferon daily for 16 weeks; placebo followed by 1 million units of interferon daily for 16 weeks; or observation with no treatment. RESULTS Hepatitis B e antigen and hepatitis B viral DNA disappeared from serum significantly more often in the patients given prednisone plus interferon (16 of 44 patients, or 36 percent) or 5 million units of interferon alone (15 of 41; 37 percent) than in the untreated controls (3 of 43; 7 percent; P less than 0.001); the difference between those given 1 million units of interferon (7 of 41; 17 percent) and the controls was not significant. The strongest independent predictor of a response to treatment was the amount of hepatitis B viral DNA in serum at entry (P less than 0.0001). Of the 38 patients who responded to interferon, 33 (87 percent) had normal serum aminotransferase levels after therapy; 11 patients who responded (29 percent), but no controls, lost the hepatitis B surface antigen. Blinded histologic assessment revealed a significant improvement in periportal necrosis in the treated patients (P = 0.03). CONCLUSIONS In chronic hepatitis B, treatment with interferon alfa-2b (5 million units per day for 16 weeks) was effective in inducing a sustained loss of viral replication and achieving remission, assessed biochemically and histologically, in over a third of patients. Moreover, in about 10 percent of the patients treated with interferon, hepatitis B surface antigen disappeared from serum.

Abstract
We report that treatment of 2.2.15, a human hepatoblastoma-derived cell line in which hepatitis B virus is actively replicating, with the carbocyclic analogue of 2'-deoxyguanosine [Shealy, Y. F., O'Dell, C. A., Shannon, W. M. & Arnett, G. (1984) J. Med. Chem. 27, 1416-1421] resulted in the nearly complete cessation of viral replication, as monitored by the absence of both intracellular episomal and secreted viral DNAs and by the absence of viral DNA polymerase activity. The drug was nontoxic in concentrations up to 200 times the minimum effective inhibitory concentration.

Abstract
Ten patients with severe chronic type B hepatitis confirmed by liver biopsy were treated with prednisolone for eight weeks and followed up for more than one year. The patients were comprised of 6 males and 4 females, ages 17 to 45 (mean 32) yrs. Serum alanine aminotransferase (ALT) was elevated more than one month before the treatment in all (mean: 379 U/L, range: 87 to 772 U/L). Initial serological tests showed hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) in all and hepatitis B virus DNA (HBV-DNA) in 7/10 (70%). Liver biopsy showed severe chronic active hepatitis with confluent necrosis or acinar hepatitis in all. Prednisolone, 60 mg/day, was administered initially and the dose was tapered every 2 weeks over the 8 weeks period. Two to six months after cessation of treatment, 5 of 10 patients showed a disappearance of HBeAg and serum HBV-DNA and return of serum ALT level to normal (responders). The initial serum ALT level in responders was slightly higher than that of non-responders (mean: 404 vs. 355 U/L), but there was no statistical significance. Among 5 responders, serum HBV-DNA was detected in three patients initially and was transiently detected in one patient during treatment. In non-responders, HBeAg persisted during and after the treatment and serum HBV-DNA persisted in three, but serum ALT was decreased in all. One patient who did not show any clinical or serological improvement, died of jaundice, ascites and hepatic encephalopathy 4 months later.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The relationship between host immune state and hepatic inflammation and infection pattern of the Duck hepatitis B virus (DHBV) was investigated by experimental transmission of DHBV into 98 Japanese 7-day-old ducklings that had been pretreated with immunoregulatory drugs including cyclophosphamide, OK 432, and a steroid hormone. Immunosuppressive treatment with cyclophosphamide revealed an extension of the viremic period associated with an absence of inflammatory changes in the liver. Although immunostimulating treatment with OK 432 showed a remarkable accumulation of inflammatory cells in the liver, the viremic period was not shortened. Treatment with a steroid used as a immunosuppressant did not suppress the hepatitis; moreover, it increased viral DNA replication and extended the viremic period. This phenomenon of viral replication seemed to be caused by the direct effects of the steroid. Alteration of DHBV infection by modifying the host immune state is quite similar to that of hepatitis B virus (HBV) in humans. In DHBV infection, the host immune state seemed to have a considerable role in determining the infection pattern and degree of hepatitis activity. DHBV may be a helpful model of HBV for studying host-viral interaction and the immunological mechanism of viral hepatitis.

Abstract
Eleven patients of Chinese origin experienced spontaneous reactivation of chronic active hepatitis B. Eight HBsAg-positive patients were followed for an average of 15 months prior to, while three others presented during reactivation. Fatigue, hepatomegaly and jaundice were frequent findings. Elevation of both serum ALT (average = 1,212 units per liter) and hepatitis B virus DNA levels were noted in all patients, and reactivation lasted an average of 4.4 months. During resolution, clinical symptoms abated, serum ALT levels reverted toward normal, and in nine patients, the hepatitis B virus DNA values became undetectable. All patients lacked evidence for acute hepatitis A, Epstein-Barr Virus, cytomegalovirus or hepatitis delta virus infection. Histologic findings of liver tissue from eight patients showed piecemeal necrosis and fibrosis. Within the parenchyma, varying degrees of hepatocytolysis with cuffing, perivenular necrosis and acidophilic bodies were noted. Ground-glass cells and regenerative changes also were observed. Cirrhosis was not present in any of the liver biopsies. These findings suggest that spontaneous reactivation of hepatitis B occurs in heterosexual patients with chronic active hepatitis B and contributes to chronic inflammation and to the progression of their liver disease.

Abstract
Serum levels of antibody to hepatitis B core antigen and IgM antibody to hepatitis B core antigen were tested in 15 patients who participated in a randomized, placebo-controlled trial of a 28-day course of prednisolone therapy. During treatment, serum levels of antibody to hepatitis B core antigen and IgM antibody to hepatitis B core antigen decreased in all 10 treated patients, but in none of five controls (p less than 0.05). Also during therapy, ALT activity decreased by an average of 50% and serum IgG levels by 30% (both p less than 0.05). Serum levels of hepatitis B virus DNA and DNA polymerase activity did not change significantly. Four to 10 weeks after discontinuation of prednisolone, a rebound of serum ALT and IgM antibody to hepatitis B core antigen levels occurred, which usually resolved within the subsequent months of follow-up evaluation. In three patients, however, there was a prolonged exacerbation of the disease following prednisolone withdrawal; in these three, levels of IgM antibody to hepatitis B core antigen and ALT remained elevated above pretreatment values. The close correlation between changes in serum ALT activity and IgM antibody to hepatitis B core antigen levels suggests that corticosteroids can modulate disease activity in chronic type B hepatitis by suppression of the host-immune response to hepatitis B virus antigens.

Abstract
The effect of a short course of prednisone therapy was evaluated in 8 patients with liver biopsy-verified chronic persistent hepatitis B. In 6 of the 8 (75%) patients, an abrupt fall in serum alanine aminotransferase levels after the initiation of prednisone was noted, and in 4 patients, there was an increase in serum alanine aminotransferase values after prednisone was discontinued. However, the serum levels of hepatitis B virus deoxyribonucleic acid were consistently greater than or equal to 200 pg before, during, and after the course of treatment in 7 of the 8 (87.5%) patients. All patients were initially hepatitis B e antigen-positive and remained so during the study period. These findings indicate that, unlike some patients with chronic active hepatitis B, immunosuppression with prednisone had no effect in altering hepatitis B viral replication in patients with chronic persistent hepatitis.

Abstract
We investigated the efficacy of a short course of prednisone therapy in 20 patients with histologic evidence of chronic active hepatitis B. Sixteen of 20 prednisone-treated patients who were initially serum hepatitis B virus DNA-positive had a transient elevation of their serum ALT activity on withdrawal of prednisone. Subsequently, 14 of these 16 patients (87.5%) became persistently negative for serum hepatitis B virus DNA, and 10 also lost their HBeAg. In addition, there was a significant fall in serum ALT levels and HBsAg titers up to 12 months of follow-up in the prednisone-treated group. Five of 20 (25%) prednisone-treated patients experienced a transient episode of hepatic decompensation coinciding with the peak of enzyme elevation. To contrast, only 3 of 15 (20%) initially hepatitis B virus DNA-positive matched untreated patients followed during the same time period became negative for serum hepatitis B virus DNA, and no significant changes in serum ALT values or HBsAg titers were noted over the 12-month study period. Thus, patients with chronic active hepatitis B appear to be responsive to immunologic manipulation with prednisone as indicated by a pronounced rebound immune response and clearance of hepatitis B virus DNA with improvement in liver disease activity.

Abstract
B and T lymphocyte function was studied in 10 patients with chronic type B hepatitis before, during and after a 28-day course of prednisolone therapy. Lymphocyte function was assessed by measuring the in vitro synthesis of immunoglobulin by peripheral blood mononuclear cells stimulated with pokeweed mitogen and by assaying lymphocyte proliferation in response to B and T cell mitogens. During high dose prednisolone therapy, there was a decrease in immunoglobulin synthesis by peripheral blood mononuclear cells and in lymphocyte proliferation to all mitogens. Studies using separated B and T cells showed that prednisolone treatment led to a decrease in both helper and suppressor T cell function but an enhancement of primary B cell function. When prednisolone was withdrawn, lymphocyte function rapidly returned to baseline levels. During prednisolone therapy, serum aminotransferase activities decreased by an average of 50%. In all patients, there was a subsequent rebound increase in serum aminotransferase activities 4 to 10 weeks after withdrawal of prednisolone. This was accompanied by a striking increase in suppressor T lymphocyte activity without significant changes in either helper T cell or B cell function. The close correlation between changes in helper and suppressor T lymphocyte function and serum aminotransferase activities during and after immunosuppressive therapy suggests that immunoregulatory T lymphocytes may play an important role in the pathogenesis of chronic type B hepatitis.

Abstract
Eleven patients with hepatitis B e antigen (HBeAg)-positive chronic active hepatitis B were treated with an 8-wk course of prednisone followed by 28 days of adenine arabinoside 5'-monophosphate. Five individuals had a complete response (loss of HBeAg and DNA polymerase) whereas 3 had a partial response (sustained loss of DNA polymerase but persistence of HBeAg). At the present time 27 +/- 3 mo has elapsed since the completion of therapy, and 4 of 5 complete responders remain negative for replicative markers while the fifth person exhibited transient reactivation of infection. Elevated DNA polymerase has reappeared in two of the three partial responders, in one 22 mo after completion of therapy. These encouraging results have led to a randomized, controlled trial using short-term prednisone followed by recombinant alpha-interferon.
