Efficacy and resistance of entecavir following 3 years of treatment of Japanese patients with lamivudine-refractory chronic hepatitis B

Purpose

Lamivudine treatment of chronic hepatitis B (CHB) is associated with frequent resistance and loss of clinical benefit. We present outcomes of lamivudine-refractory Japanese patients treated with entecavir for 3 years.

Methods

Eighty-two patients refractory to lamivudine therapy received entecavir 0.5 or 1 mg daily for 52 weeks in phase II study ETV-052, directly entered rollover study ETV-060, and received entecavir 1 mg daily. Responses were evaluated among patients with available samples.

Results

After 96 weeks in ETV-060 (148 weeks total entecavir treatment time), 55% (36/65) of patients had hepatitis B virus (HBV) DNA of >400 copies/mL, 85% (52/61) had alanine aminotransferase (ALT) of ≥1 × upper limit of normal (ULN), and 14.6% (7/48) achieved HBe seroconversion. A subset of 42 patients received entecavir 1 mg from phase II baseline through 148 weeks: 54% (19/35) had HBV DNA of >400 copies/mL, 84% (27/32) had ALT of ≥1 × ULN, and 15% (4/27) achieved HBe seroconversion. Sixteen patients in the 1-mg subset had baseline and week 148 evaluable biopsy pairs: 81% (13/16) showed histologic improvement and 38% (6/16) showed improvement in fibrosis. Genotypic resistance to entecavir emerged in 31 patients for a 3-year cumulative resistance probability of 35.9%. Entecavir was generally well tolerated during ETV-060, with no on-treatment ALT flares.

Conclusions

Long-term entecavir treatment of lamivudine-refractory CHB resulted in virologic suppression, ALT normalization, and improvements in liver histology. Resistance was consistent with that observed in worldwide studies.     

Efficacy of ursodeoxycholic acid for Japanese patients with autoimmune hepatitis

Purpose

This study aimed to investigate the efficacy of ursodeoxycholic acid (UDCA) for Japanese patients with autoimmune hepatitis (AIH).

Methods

One hundred forty-seven patients were investigated.

Results

As initial treatment, 25 patients received UDCA (300–600 mg/day) monotherapy (UDCA group), 40 received a combination of prednisolone (PSL) (≥20 mg/day) and UDCA (combination group), 68 received PSL monotherapy (PSL group), and 14 received other treatments. During the follow-up, in the UDCA group, PSL was added to 8 of 12 patients failing to achieve the normalization of serum transaminase levels with UDCA monotherapy. Cumulative incidence of the normalization of serum transaminase levels was 64% in the UDCA group, 95% in the combination group, and 94% in the PSL group (log-rank test, P = 0.0001). UDCA group required longest periods until the normalization of serum transaminase levels. Eleven patients, who achieved persistent normalization of serum transaminase levels with UDCA monotherapy, did not reach liver failure or develop hepatocellular carcinoma for 49.7 (range = 13.4–137.3) months. Meanwhile, during the taper of PSL, doses of PSL at the initial relapse were lower in patients treated with PSL and UDCA than in those treated with PSL monotherapy, and initial relapse occurred earlier in patients treated with PSL monotherapy.

Conclusions

UDCA monotherapy is effective for some Japanese AIH patients; however, UDCA monotherapy for patients with either high-grade inflammatory activity or poor residual capacity of liver function is not recommended because they may reach liver failure before achievement of remission. Meanwhile, additional use of UDCA during the taper of corticosteroids may be effective for the prevention of early relapse.     

Virologic, serologic, and biochemical outcomes through 2 years of treatment with entecavir and lamivudine in nucleoside-naïve Chinese patients with chronic hepatitis B: a randomized, multicenter study

Purpose

Entecavir demonstrated superior virologic and biochemical benefits over lamivudine at 48 weeks in nucleoside-naïve Chinese patients with chronic hepatitis B (CHB). We evaluated the effect of continued entecavir and lamivudine treatment in patients who continued treatment in year 2 and the off-treatment durability of patients who achieved a protocol-defined consolidated response at week 48.

Methods

Chinese adults (n = 519) with CHB were randomized to a minimum of 52 weeks of treatment with entecavir 0.5 mg/day or lamivudine 100 mg/day. Patients with a consolidated response at week 48 (HBV DNA <0.7 MEq/ml for ≥24 weeks, ALT <1.25 times ULN, and, if HBeAg(+) at baseline, loss of HBeAg for at least 24 weeks) stopped treatment at week 52 and were followed off-treatment. Patients with a partial response at week 48 (HBV DNA <0.7 MEq/ml in the absence of other criteria for a consolidated response) could continue blinded treatment for up to 96 weeks. Patients were assessed for HBV DNA, ALT normalization, safety, and, if HBeAg(+) at baseline, for HBe seroconversion. Cumulative proportions of all treated patients who ever achieved these responses were also analyzed.

Results

Among patients treated during year 2 (entecavir: n = 193; lamivudine: n = 145), 74% of entecavir-treated and 41% of lamivudine-treated patients had HBV DNA <300 copies/ml by PCR at end of dosing and 96% of entecavir-treated and 82% of lamivudine-treated patients normalized ALT. Eleven percent of entecavir-treated versus 19% of lamivudine-treated patients underwent HBe seroconversion during year 2. Cumulative confirmed analysis for all treated patients through 96 weeks showed that 79% of entecavir-treated versus 46% of lamivudine-treated patients (p < 0.0001) achieved HBV DNA <300 copies/ml by PCR. Similar proportions of entecavir- and lamivudine-treated patients achieved confirmed ALT normalization and HBe seroconversion. Safety profile was comparable for both treatment groups.

Conclusions

Through 96 weeks of treatment, entecavir resulted in continued clinical benefit in nucleoside-naïve Chinese patients with CHB, with a safety profile comparable with lamivudine.     

Gastrointestinal system manifestations in juvenile systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disease which may involve gastrointestinal system (GIS). The aim of this study was to present GIS manifestations of pediatric SLE patients. The medical files of 69 children with SLE followed between January 2011 and January 2016 were reviewed. All fulfilled the Systemic Lupus International Collaborating Clinics criteria. All patients (≤18 years of age) with GIS manifestations were included. GIS manifestations were observed in 19 (27.5%) out of 69 SLE patients and present at the time of SLE diagnosis in 13 (68.4%). The GIS manifestations due to SLE were autoimmune hepatitis (AIH) (n = 8) and lupus enteritis (n = 1). Manifestations associated with SLE were hepatomegaly and hypertransaminasemia due to macrophage activation syndrome (MAS) (n = 3) and hepatic steatosis (n = 1). GIS manifestations as a result of the adverse events of drugs were as follows: toxic hepatitis (n = 3; associated with methotrexate and nonsteroidal anti-inflammatory drugs in one, methotrexate in another, and azathioprine in another patient), azathioprine-induced cholestatic hepatitis (n = 1), and gastritis associated with corticosteroid (n = 1). In one patient, acute appendicitis occurred as a coincidence. In this study, one of every five pediatric SLE patients had GIS-related manifestations. GIS involvement may occur as an initial manifestation of the disease.     

Síndrome de superposición: hepatitis autoinmune y colangitis biliar primaria. Resultados a largo plazo de una cohorte retrospectiva en un hospital universitario

Background

Autoimmune hepatitis (AIH) with characteristics of primary biliary cholangitis (PBC) is known as overlap syndrome. Its prevalence and prognosis have not yet been determined comparatively with AIH.

The liver in collagen diseases: pathologic study of 160 cases with particular reference to hepatic arteritis, primary biliary cirrhosis, autoimmune hepatitis and nodular regenerative hyperplasia of the liver

AIMS/BACKGROUND: Among patients with collagen diseases, liver enzyme abnormalities are a relatively common phenomenon. To establish the liver pathology in collagen diseases, detailed pathologic studies were performed on the hepatic diseases in many patients, including various kinds of collagen diseases. METHODS: The livers from 160 patients (120 autopsy and 40 liver biopsy patients) were examined pathologically: 73 with systemic lupus erythematosus (SLE), 32 with rheumatoid arthritis (RA), 18 with polymyositis and dermatomyositis (PM and DM), 15 with systemic sclerosis (SSc), 11 with mixed connective tissue disease (MCTD) and 11 with polyarteritis nodosa (PAN). RESULTS: Liver diseases were divided into three groups: hepatic arteritis, liver diseases associated with collagen diseases (primary biliary cirrhosis, PBC; autoimmune hepatitis, AIH; nodular regenerative hyperplasia of the liver, NRH) and other liver diseases. Hepatic arteritis presenting the features of the PAN type of necrotizing arteritis was found in 27 autopsy patients. The incidence of arteritis in autopsy patients was 100% in PAN and 8.3-25% in other collagen diseases. Primary biliary cirrhosis was observed in 9 patients, 7 of whom (3 with SSc, 2 with RA, 1 with PM and DM, and 1 with MCTD) had antimitochondrial antibodies (AMA)-positive PBC, and 2 SLE patients had AMA-negative PBC. Three patients (2 with SLE and 1 with MCTD) were diagnosed clinicopathologically as having AIH. However, 3 patients (1 with SLE, 1 with MCTD and 1 with PM and DM) with clinical, biochemical and serologic data indicating probable AIH were excluded from the group with AIH association because of the liver histology (no characteristic features of AIH) and clinical course. These results indicated that data without histologic assessments of the liver are not adequate for diagnosing AIH in collagen diseases. Nodular regenerative hyperplasia of the liver was observed in 7 patients (5 with SLE, 1 with SSc and 1 with PAN). CONCLUSION: The present study offers data that are useful for the diagnosis and treatment of patients with collagen diseases and liver abnormalities.     

Association of autoimmune hepatitis and systemic lupus erythematodes: A case series and review of the literature

Liver test abnormalities have been described in up to 60% of patients with systemic lupus erythematodes (SLE) at some point during the course of their disease. Prior treatment with potentially hepatotoxic drugs or viral hepatitis is commonly considered to be the main cause of liver disease in SLE patients. However, in rare cases elevated liver enzymes may be due to concurrent autoimmune hepatitis (AIH). To distinguish whether the patient has primary liver disease with associated autoimmune clinical and laboratory features resembling SLE - such as AIH - or the elevation of liver enzymes is a manifestation of SLE remains a difficult challenge for the treating physician. Here, we present six female patients with complex autoimmune disorders and hepatitis. Patient charts were reviewed in order to investigate the complex relationship between SLE and AIH. All patients had coexisting autoimmune disease in their medical history. At the time of diagnosis of AIH, patients presented with arthralgia, abdominal complaints, cutaneous involvement and fatigue as common symptoms. All patients fulfilled the current diagnostic criteria of both, AIH and SLE. Remission of acute hepatitis was achieved in all cases after the initiation of immunosuppressive therapy. In addition to this case study a literature review was conducted.     

Centrilobular necrosis in acute presentation of Japanese patients with type 1 autoimmune hepatitis

AIM:To compare clinicopathological features of acute presentation of type 1 autoimmune hepatitis(AIH) with or without centrilobular necrosis(CN).METHODS:Our study comprised 41 patients with biopsy-proven acute presentation(acute exacerbation phase 36,acute hepatitis phase 5) of type 1 AIH at our hospital from 1975 to 2009.Elevated serum alanine aminotransferase(ALT)(> 5x upper limit of normal) identified acute presentation of the disease.We compared clinicopathological features of these AIH patients with or without CN.The data used for analysis included patient background(age,sex,type of disease,presence of complications with other autoimmune diseases,human leukocyte antigen,and International Autoimmune Hepatitis Group score),clinical parameters at presentation(ALT,alkaline phosphatase,IgG,anti-nuclear antibodies,and anti-smooth muscle antibodies),histology and therapy.RESULTS:CN was found in 13(31.7%) patients with acute presentation(acute exacerbation phase 10,acute hepatitis phase 3) of AIH.Serum IgG levels of patients with CN were significantly lower than those of patients without CN(mean:2307 mg/dL vs 3126 mg/dL,P < 0.05),while antinuclear antibody-negative rates were significantly higher(30.7%vs 3.5%,P < 0.05).However,other clinical features were similar between the two groups.The frequency of advanced fibrosis in patients with CN was significantly lower than in patients without CN(F0-2:84.6% vs 35.7%,F3-4:15.4% vs 64.3%,P < 0.05).Other histological features were similar between the two groups.Although there was no significant difference between groups when evaluated using the revised original score(12 vs 14),the simplified AIH score of patients with CN was significantly lower(6 vs 7,P < 0.05).Frequency of DR4 was similar between patients with and without CN.CONCLUSION:CN is observed in both Japanese patients with acute hepatitis phase and acute exacerbation phase of type 1 AIH,although AIH with CN often shows clinical features of the genuine acute form.     

Evaluation of long-term entecavir treatment in stable chronic hepatitis B patients switched from lamivudine therapy

Purpose

Current Japanese guidelines recommend that patients should be switched from lamivudine to entecavir when they meet certain criteria. This analysis examines the efficacy and safety of long-term entecavir therapy in patients who were switched to entecavir after 24 weeks’ lamivudine therapy in Japanese studies ETV-047 and ETV-060.

Methods

The Phase II Japanese study ETV-047 assessed the efficacy of different entecavir doses when compared with lamivudine. A total of 33 Japanese patients who received lamivudine 100 mg daily in ETV-047 entered the open-label rollover study ETV-060 and subsequently received treatment with entecavir 0.5 mg daily. Hepatitis B virus (HBV) DNA suppression, alanine aminotransferase (ALT) normalization, hepatitis B e antigen (HBeAg) seroconversion, and resistance were evaluated among patients with available samples for up to 96 weeks. Safety was assessed throughout the treatment period.

Results

After 96 weeks of entecavir therapy in ETV-060, 90% of patients achieved HBV DNA <400 copies/mL as compared to 21% of patients who completed 24 weeks of lamivudine therapy in ETV-047. Increasing proportions of patients achieved ALT normalization and HBeAg seroconversion following long-term entecavir treatment. No patients experienced virologic breakthrough, and substitutions associated with entecavir resistance were not observed in patients with detectable HBV DNA. Entecavir was well tolerated during long-term treatment.

Conclusions

Switching lamivudine-treated patients with chronic hepatitis B to entecavir results in increased virologic suppression with no evidence of resistance through 2 years of entecavir therapy. These findings support recommendations in the current Japanese treatment guidelines that stable lamivudine patients should be switched to entecavir.     

Clinical features of hepatocellular carcinoma in patients with autoimmune hepatitis in Japan

Background

The occurrence of hepatocellular carcinoma (HCC) in patients with autoimmune hepatitis (AIH) is rare compared to that in patients with viral hepatitis. To clarify the status of HCC in patients with AIH in Japan, the clinical features of HCC in patients with AIH were analyzed.

Methods

A primary survey gathered data from 496 member institutions of the Liver Cancer Study Group of Japan, and a secondary survey collected additional information from 250 HCC patients out of a total 4869 AIH patients who were identified in the primary survey.

Results

Of the 250 patients identified through the secondary survey, 127 patients (50.8 %) from throughout Japan were found to have HCC. The mean age at diagnosis of HCC was 69 years, and the male-to-female ratio was 1:5.7. The mean period from diagnosis of AIH to detection of HCC was 8 years, and Child–Pugh status at the time of HCC diagnosis was class A in 61.8 %; of the patients analyzed, 77.9 % also had cirrhosis of the liver. The mean value of maximum tumor diameter was 4.3 cm, and clinical stages were I in 20.1 % of patients, II in 47.6 %, III in 23.4 %, and IV in 8.9 %. The therapeutic modality used was surgery in 30.2 %, percutaneous therapy in 29.5 %, transcatheter arterial chemoembolization in 36.4 %. Cumulative survival rate was 85.4 % at one year.

Conclusion

The survey results showed that HCC developed in 5.1 % of patients with AIH in Japan, with cirrhosis of the liver commonly found in elderly individuals; when HCC was diagnosed at an early clinical stage, in many cases, the liver function was relatively preserved. After diagnosis of AIH, observation of its progression with close attention to potential HCC complications is necessary.     

Clinical and laboratory profiles of systemic lupus erythematosus associated with Sjögren syndrome in China: a study of 542 patients

This study aims to investigate the clinical and laboratory features of systemic lupus erythematosus (SLE) patients associated with Sjögren syndrome (SS) in China, as well as its similarities to and differences from SLE patients without SS. A group of 542 consecutive unselected SLE patients was recruited. Diagnosis of SLE was made according to 1997 revised American College of Rheumatology SLE criteria; SS was diagnosed using the American–European classification criteria. Clinical and laboratory parameters in SLE patients with SS (SLE-SS) were compared with those in SLE patients without SS (SLE-no SS). Overall, SS was identified in 35 SLE patients (6.5%); the onset of SS preceded the development of SLE in 17 of them (48.6%). Compared with the SLE-no SS group (35.8?±?10.5 years), patients with SLE-SS (41.3?±?11.6 years) were significantly older (P?=?0.003), had a higher frequency of anti-Ro/SSA, anti-La/SSB, and anti-dsDNA antibodies, but had a significantly lower frequency of renal involvement. This study demonstrates that SLE-SS may be a subgroup of patients with characteristic clinical and laboratory features. To improve the treatment outcomes in SLE-SS patients, more specific treatment should be applied based on those factors.     

自身免疫性肝炎、原发性胆汁性胆管炎及其重叠综合征患者临床特征比较*

Is there a difference in systemic lupus erythematosus with and without Raynaud’s phenomenon?

The aim of this study was to assess the association between Raynaud’s phenomenon (RP) and specific capillaroscopic findings in patients with SLE and particular clinical manifestations of the disease. A total of 79 patients with SLE were included in the study: 44 of them (43 women) with RP and 35 (32 women) age-, sex-, and disease-duration-matched patients with SLE without RP. Demographic variables, clinical manifestations, laboratory and nailfold capillaroscopy findings were compared between the two groups. Central nervous systemic involvements (P = 0.0038) and peripheral neuropathy (P = 0.0336) were significantly more common in SLE patients with RP, while secondary Sjögren’s syndrome (P = 0.0363) was more common in SLE patients without RP. RP occurred in 52 % of patients before SLE onset while 48 % of patients developed RP after they had been diagnosed with SLE. Arthritis/arthralgia (P = 0.0073) was significantly more common in patients who had been diagnosed with RP before the onset of SLE, while mucosal ulcers were more common in patients who contracted RP after the onset of SLE (P = 0.0258). Enlarged capillaries (P = 0.0482), presence of avascular areas (P = 0.0476), capillary hemorrhages (P = 0.0482), and granular blood flow (P = 0.0482) were more common in patients with SLE who also suffered from RP, than in patients with SLE without RP. The frequency of normal (63.6 vs. 82.9 %, P = 0.100) and nonspecific (25 vs. 17.1 %, P = 0.5696) capillaroscopy findings were similar in either groups. Scleroderma-like pattern of capillaroscopy finding was only found in patients with RP [(11.4 %), P = 0.0482]. RP in our patients with SLE was associated with specific clinical manifestations, indicating that prognostic relevance of RP in SLE should be evaluated.     

Efficacy and safety of laparoscopic splenectomy in thrombocytopenia secondary to systemic lupus erythematosus

This study aims to investigate the efficacy and safety of laparoscopic splenectomy (LS) in the management of refractory thrombocytopenia associated with systemic lupus erythematosus (SLE). From January 2003 to February 2012, 20 patients underwent splenectomy for thrombocytopenia associated with SLE. Of these, 11 underwent open (SLE-OS group) and 9 underwent laparoscopic splenectomy (SLE-LS group). Another 15 patients with ITP underwent LS (ITP-LS group) were categorized as the control group. Surgical indications, perioperative details, and short- (90 days) and long- (median, 42 months) term hematological outcomes were assessed. Splenectomy was successful in all 20 SLE patients. The mean platelet count increased from 23?×?10⁹/L before splenectomy to 289.2?×?10⁹/L and 144.2?×?10⁹/L after 3 and 6 months, respectively, and was 115.5?×?10⁹/L at the last visit, with a 3-month complete response (CR) rate of 100 %. After a median follow-up of 42 months, 17 patients (85 %) had a CR or partial response (PR) to splenectomy plus medical therapy. SLEDAI score and dosage of steroids decreased significantly after splenectomy. None of these patients experienced any postoperative infection, bleeding, or thrombotic events. SLE-LS group had lower volumes of estimated blood loss and postoperative drainage and shorter postoperative hospital stay than SLE-OS group. There were no statistically significant differences between the SLE-LS and ITP-LS groups in operation time, estimated blood loss, and postoperative hospital stay. Splenectomy is effective and safe in the management of refractory thrombocytopenia secondary to SLE. LS may be safe and effective in thrombocytopenia associated with SLE.     

Distinct antibody profile: a clue to primary antiphospholipid syndrome evolving into systemic lupus erythematosus?

We have performed a retrospective study to determine if patients with antiphospholipid syndrome that developed systemic lupus erythematosus (APS/SLE) had distinct clinical and/or serological features. All 80 primary APS (PAPS) patients followed up at our APS unit were included in the study and divided into two groups: 14 APS/SLE and 66 PAPS. Prior or at onset of lupus manifestations, six patients were uniformly negative for lupus and Sjögren autoantibodies, and the other eight patients had persistent positive. In the first year after diagnosis of SLE, three patients remained with negative antibodies, the other seven patients maintained the same antibodies, and four patients developed other antibodies. APS/SLE group had a significant lower mean age at PAPS diagnosis (26.0?±?8.0 vs. 34.2?±?11.9 years, p?=?0.03) and a longer disease duration (14.0?±?7.0 vs. 6.0?±?5.0 years, p?<?0.0001). The mean time for PAPS to develop SLE was 5.2?±?4.3 years. The typical clinical and laboratorial findings of APS did not discriminate both groups of patients. At lupus onset, antinuclear antibodies were more frequently observed in those who evolved to SLE (100 vs. 51.5 %, p?=?0.0005). Anti-double-stranded DNA (dsDNA), anti-ribosomal P, anti-Ro/SS-A, anti-La/SS-B, and anti-U1RNP antibodies were exclusively found in the APS/SLE patients, whereas anti-Smith (Sm) antibodies were not detected in both groups. The detection of a distinct subgroup of lupus-associated autoantibody in PAPS patients seems to be a hint to overt SLE disease, particularly in those patients with young age at diagnosis.     

Prevalence,severity, and clinical features of acute and chronic pancreatitis in patients with systemic lupus erythematosus

Pancreatitis is a rare, life-threatening complication of systemic lupus erythematosus (SLE). This study aimed to describe the clinical features of acute pancreatitis (AP) and chronic pancreatitis (CP) in patients with SLE. Data of patients who fulfilled the revised criteria of the American Rheumatism Association for diagnosis of SLE were retrospectively analyzed. SLE activity was graded according to the SLE Disease Activity Index. Logistic regression analysis was conducted to find out independent associations. Survival rates were estimated by using Kaplan–Meier plots. This study included 5665 SLE patients admitted between January 1983 and January 2014, of whom 52 patients were diagnosed with pancreatitis. Pancreatitis prevalence in SLE patients was 0.92 % (52/5665). AP (0.8 %, 46/5665) was more prevalent than CP (0.1 %, 6/5665), presented mostly during active SLE, and affected more organs. Hypertriglyceridemia occurred in 76.9 % of AP patients and in none of the CP patients. AP patients were divided into severe (n = 10) or mild (n = 20) cases. The average triglyceride level in severe AP cases was higher than that in mild AP cases (P = 0.006), and the mortality rate of lupus-associated AP was 32.6 % (15/46). Concomitant infections and thrombocytopenia were independently associated with poor prognosis (P < 0.001, P = 0.028, respectively). There were significant differences in the clinical manifestations of AP and CP. Patients with severe AP were found to have a higher incidence of concomitant infection and serum triglyceride levels. Concomitant infections and thrombocytopenia were independent risk factors for poor prognosis.     

Clinical features of antinuclear antibodies-negative type 1 autoimmune hepatitis

Aim:  Antinuclear antibodies (ANA) are the main serologic markers of type 1 autoimmune hepatitis (AIH); however 20–30% of patients are negative for ANA. We assessed the clinical features of ANA-negative patients.
Methods:  A retrospective analysis was performed of 176 patients with type 1 AIH (153 females, median age 55 years). A diagnosis of AIH was made based on the revised scoring system proposed by the International Autoimmune Hepatitis Group. ANA titers were measured using a standard indirect immunofluorescence technique.
Results:  Thirty-eight patients (22%) had low titers of ANA (1:40 or 1:80), and 114 (65%) had high titers (≥ 1:160). Of 24 ANA-negative patients, 15 were positive for smooth muscle antibodies (SMA). Three of nine both ANA- and SMA-negative patients developed ANA during follow-up. The other six were diagnosed based on histological characteristics. Thirteen ANA-negative patients relapsed after the normalization of serum alanine aminotransferase (ALT) levels. ANA-negative patients more frequently showed acute presentation and, at presentation, had lower serum immunoglobulin G levels, higher serum levels of bilirubin and transaminase, and higher frequencies of histological acute hepatitis and zone 3 necrosis than those with high titers. However, the frequency of advanced stage of fibrosis was similar. The response to corticosteroids was not different among the three groups.
Conclusions:  ANA-negative type 1 AIH shows acute-onset more frequently but may include not only acute autoimmune hepatitis, but also acute exacerbation of inactive chronic disease. Regarding the diagnosis of ANA-negative AIH, the determination of ANA during follow-up and the response to immunosuppressive treatment may be helpful.     

Autoimmune hepatitis in a patient with systemic lupus erythematosus

We report a female patient with systemic lupus erythematous (SLE), hyperbilirubinemia and high serum value of ALT. International autoimmune hepatitis (AIH) score showed definite AIH before treatment, but autoantibodies could not make a differential diagnosis of AIH and SLE-associated hepatitis. Liver biopsy showed periportal hepatitis with lymphoplasmacytic infiltration, but neither parenchymal collapse nor rosette formation could be found. Pericarditis, pleuritis and nephritis were improved as well as liver injury after administration of prednisolone, and no repeated attack has been present these 4 years. Our case suggested invalidity of AIH score among patients of SLE, and liver histology should be inferred most important at present to make a differential diagnosis of lupus hepatitis or AIH in patients with SLE.AcknowledgementThe paper was reviewed by Dr. D. Murouzeck whose native language is English.

Long-term follow-up of patients with difficult to treat type 1 autoimmune hepatitis on Tacrolimus therapy

Introduction: Autoimmune hepatitis (AIH) is an immune-mediated liver disease, which requires long-term immunosuppression. Ten to fifteen percent of patients experience insufficient/intolerance response to standard therapy. Although alternate immunosuppression has been applied, there is little long-term data reported on safety, efficacy, steroid-dose reduction and disease evolution in patients with difficult AIH who were on Tacrolimus therapy. Materials and methods: Clinical, biochemical, immunological profiles, treatment response and side effects of 17 AIH patients treated with Tacrolimus between 2003 and 2014 were analyzed from two tertiary referral liver centers. Results: Tacrolimus was started on 16/17 (94%) patients due to insufficient response to standard therapy. The median duration of treatment was 24 months and patients were followed up for median of 60 months. Tacrolimus dosage was 2 mg/day (median). During first year of therapy, there was a significant improvement in immunoglobulin G and Aspartate transaminase level. 9/17 (52%) compliant and definite AIH patients remained on Tacrolimus at end of follow-up and prednisolone dose reduction was achieved from 10 to 5 mg. All patients are alive and one patient underwent liver transplantation. 4/17 (24%) patients developed overlap with primary sclerosing cholangitis over follow-up period. No significant side effects were observed with Tacrolimus therapy. Conclusion: Tacrolimus could be used in compliant patients with difficult to treat AIH in experienced centers. Its use is safe and can improve liver biochemistry, IgG and reduce steroid requirement. However, due to the lack of immunomodulatory effect, unmet need for effective immune-regulatory therapies still remain for AIH patients.
