The development of connective tissue diseases in patients with autoimmune hepatitis: a case series

Explore comorbidities associated with systemic lupus erythematosus: a total population-based case-control study

BACKGROUND

Because of the increasing incidence and overall burden of systemic lupus erythematosus (SLE), efforts have been made to identify the factors that contribute to SLE onset and progression.

AIM

We conducted a total population-based case-control study to explore the prior comorbidities associated with SLE.

DESIGN AND METHODS

Data were collected from Taiwan's National Health Insurance Research Database. Newly diagnosed SLE patients from 1 January 2010, to 31 December 2013 (n = 2847), were exactly matched at a 1:4 ratio for gender, age, residence and insurance premium to form a non-SLE group. Multivariate conditional logistic regression with stepwise selection was used to find the prior-associated comorbidities.

RESULTS

A total of 38 prior comorbidities were associated with SLE incidence (32 positive and 6 negative associations). Positively associated comorbidities could be categorized as autoimmune-related inflammation of multiple organs including skin, blood, liver, tooth, thyroid, musculoskeletal and connective tissue. Among them, diffuse diseases of connective tissue (International Classification of Disease, Ninth Revision, Clinical Modification 710) exhibited the most robust association (OR = 5.68, 95% CI = 4.02-8.03, P < 0.001) in the 5 years before the index date. Negatively associated comorbidities could be attributed to diabetes mellitus and pregnancy related symptoms.

CONCLUSIONS

Our results supported that increased awareness of SLE may be warranted for patients with autoimmune-related comorbidities of multiple organs. However, diabetes mellitus and pregnancy related symptoms were negatively associated with SLE incidence in this study. Further studies are warranted to elucidate the possible underlying mechanism and for better understanding the pathogenesis of SLE.

Usefulness of Clinical and Laboratory Criteria for Diagnosing Autoimmune Liver Disease among Patients with Systemic Lupus Erythematosus: An Observational Study

Abnormal liver function tests are frequently observed during follow-up of patients with systemic lupus erythematosus (SLE) but data on co-existence with autoimmune liver diseases (AILD) are scarce. This retrospective study aimed to describe the prevalence of autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) among well-characterized subjects with SLE. We also evaluated whether the presence of autoantibodies to complement protein 1q (C1q) and/or ribosomal P protein (anti-ribP) are, directly or inversely, associated with AIH, as proposed in some reports. The number of screened patients was 287 (86% females), and all cases were included in a regional Swedish cohort. Each subject of the study population met the 1982 American College of Rheumatology classification criteria and/or the Fries' diagnostic principle. By applying the simplified diagnostic AIH criteria combined with persistent transaminasemia, 40 (13.9%) cases reached at least "probable AIH". However, merely 8 of these had been diagnosed with AIH (overall AIH prevalence 2.8%). Neither anti-C1q nor anti-ribP associated significantly with AIH. By applying the recent PBC guidelines, 6 (2.1%) cases were found, but only 3 of them had actually been diagnosed with PBC and one additional subject was not identified by the guidelines (overall PBC prevalence 1.4%). Compared to prevalence data from the general Swedish population, both AIH and PBC were highly overrepresented in our study population. The sensitivity of the diagnostic AIH criteria was impeccable but the specificity was less impressive, mainly due to positive ANA and hypergammaglobulinemia. Based on our findings, among subjects with SLE, the AIH criteria are less useful and liver biopsy combined with detection of other AILD-associated autoantibodies should be performed.

Diffuse Systemic Sclerosis in a Patient with Primary Biliary Cirrhosis and Autoimmune Hepatitis Overlap Syndrome: A Case Report

Systemic sclerosis (SSc) is a chronic systemic disease of unknown etiology characterized by vasculopathy, excessive accumulation of extracellular matrix, and fibrosis of the skin and other internal organs. Although its etiology remains elusive, approximately one third of SSc patients presents with additional autoimmune disease, which suggests that an autoimmune mechanism is a major component of the underlying pathophysiology. On the other hand, primary biliary cirrhosis (PBC) and autoimmune hepatitis (AIH) are two main autoimmune liver diseases. A 41-year-old female previously diagnosed with PBC/AIH overlap syndrome presented with multiple, painful brownish to erythematous firm patches on the hands, arms, axillae, neck, abdomen, and thighs. Laboratory work-up yielded positive results for anti-nuclear antibody, anti-Ro/Sjögren's-syndrome-related antigen A autoantibodies, and perinuclear anti-neutrophil cytoplasmic antibodies while punch biopsy of her left hand showed characteristics that are consistent with scleroderma. Herein, we report the first case of a patient with diffuse cutaneous SSc and concurrent PBC/AIH overlap syndrome and suggest that this coexistence of multiple autoimmune diseases is not a coincidence but rather that a common autoimmune pathogenesis may exist.

Sequential presentation of primary biliary cirrhosis and autoimmune hepatitis

BACKGROUND

Primary biliary cirrhosis (PBC)-autoimmune hepatitis (AIH) overlap syndrome is used to describe the coexistence of both diseases, with either a sequential or a simultaneous presentation in the same patient. Available studies have focused on the simultaneous form, whereas there is limited information on sequential PBC-AIH. We carried out a retrospective study of patients who sequentially developed PBC-AIH overlap syndrome.

METHODS

The medical data of 1065 patients diagnosed with PBC (n=483) and AIH (n=582) were retrospectively analyzed.

RESULTS

A sequential development of PBC-AIH was observed in 19 (1.8%) patients after a mean of 6.5 (1-14) years of follow-up. AIH developed in 12 (2.5%) PBC patients, whereas PBC occurred in seven (1.2%) patients with AIH. The baseline serologic and histological findings of patients who developed PBC-AIH were similar to those of patients with typical PBC or AIH. Eighteen patients were treated with a combination of ursodeoxycholic acid (UDCA) and immunosuppression after the diagnosis of PBC-AIH was established. One patient showed a spontaneous resolution of hepatitic flare under UDCA therapy. Biochemical remission was achieved in 16 patients, whereas three progressed to decompensated cirrhosis and required liver transplantation.

CONCLUSION

The sequential overlap of PBC-AIH can occur during the follow-up of patients with pure PBC or AIH. In our cohort, we could not identify any factors that predicted the development of this rare condition. The combination of UDCA and immunosuppression seems to be an appropriate therapy in the setting of PBC-AIH.

Autoimmune hepatitis/primary biliary cirrhosis overlap syndrome and associated extrahepatic autoimmune diseases

AIM

To assess the prevalence of concurrent extrahepatic autoimmune diseases in patients with autoimmune hepatitis (AIH)/primary biliary cirrhosis (PBC) overlap syndrome and applicability of the 'mosaic of autoimmunity' in these patients.

METHODS

The medical data of 71 AIH/PBC overlap patients were evaluated for associated autoimmune diseases.

RESULTS

In the study population, 31 (43.6%) patients had extrahepatic autoimmune diseases, including autoimmune thyroid diseases (13 patients, 18.3%), Sjögren syndrome (six patients, 8.4%), celiac disease (three patients, 4.2%), psoriasis (three patients, 4.2%), rheumatoid arthritis (three patients, 4.2%), vitiligo (two patients, 2.8%), and systemic lupus erythematosus (two patients, 2.8%). Autoimmune hemolytic anemia, antiphospholipid syndrome, multiple sclerosis, membranous glomerulonephritis, sarcoidosis, systemic sclerosis, and temporal arteritis were identified in one patient each (1.4%). A total of 181 autoimmune disease diagnoses were found in our patients. Among them, 40 patients (56.4%) had two, 23 (32.3%) had three, and eight (11.3%) had four diagnosed autoimmune diseases.

CONCLUSION

A large number of autoimmune diseases were associated with AIH/PBC overlap patients. Therefore, extended screening for existing autoimmune diseases during the routine assessment of these patients is recommended. Our study suggests that the concept of 'mosaic of autoimmunity' is a valid clinical entity that is applicable to patients with AIH/PBC overlap syndrome.

A patient of lupus presenting with myocarditis and overlapping autoimmune hepatitis

Systemic lupus erythematosus has myriad presentations. Symptomatic myocarditis and/or symptomatic autoimmune hepatitis associated with lupus are rare at presentation. Here we report a young Asian girl, who presented to us with features of symptomatic myocarditis and overlapping autoimmune hepatitis. She was eventually diagnosed to be harboring systemic lupus erythematosus, in whom rigorous management led to gratuitous recovery.

Liver autoantibodies in patients with scleroderma

Association between autoimmune liver diseases and scleroderma has been described. The purpose of this study was to study the prevalence of antimithocondrial antibody (AMA), antismooth muscle antibodies (SMA), and liver-kidney-microsomal (LKM-1) autoantibody in a cohort of 63 scleroderma patients and 100 healthy controls. The autoantibodies AMA, SMA, and LKM were determined by indirect immunofluorescence. Patients' charts were reviewed for demographic data, scleroderma form, and clinical and anti-nuclear antibody profile, aiming a comparison between patients with and without liver autoantibodies. Nine patients (14.3%) were positive for at least one of the liver autoantibodies; only one patient had both AMA and SMA positive. Antibody SMA was positive in 6.4% (4/63) patients; AMA was present in 9.52% (6/63) of them; none were positive to LKM-1. In the control group just one patient (1%) was SMA positive; the other autoantibodies were negative. There is an increased prevalence of liver autoantibodies in patients with scleroderma than in control population. These patients should be carefully followed for liver dysfunction.

Diffuse systemic sclerosis and autoimmune hepatitis: a unique association

Autoimmune hepatitis (AIH) is a chronic hepatitis of unknown etiology characterized by continuing hepatocellular necrosis and inflammation that afflicts 100,000 to 200,000 persons in the United States. It is a rare manifestation of systemic sclerosis. Only about nine reports of this association have been previously reported in the literature. Importantly, all cases had the limited clinical form of systemic. The authors describe herein the first report of a patient with diffuse systemic sclerosis who was diagnosed with AIH with positive antimitochondrial antibody and had an excellent response to immunosuppressive drugs. We also briefly review the literature regarding this issue.

[A case of systemic lupus erythematosus complicated with autoimmune hepatitis and thrombotic thrombocytic purpura]

A 51-year-old woman was admitted to our hospital because of systemic jaundice, general fatigue in August 24, 2007. She was diagnosed with systemic lupus erythematosus (SLE) as a result of a discoid rash, photosensitivity, lymphocytopenia, elevated serum anti ds-DNA antibody and a positive test for antinuclear antibody. Her laboratory data revealed severe liver dysfunction, suggesting autoimmune hepatitis (AIH). She was also diagnosed with thrombotic thrombocytic purpura (TTP) because of thrombocytopenia, hemolytic anemia, renal dysfunction and decreased ADAM-TS13 activity. The patient was treated by methylprednisolone pulse therapy, fresh frozen plasma infusion and ursodeoxycholic acid. Her symptoms and laboratory data rapidly improved and a liver biopsy was carried out. Interface hepatitis and lymphocyte infiltration were observed in the specimen. A diagnosis of definite AIH was made from her International AIH group score of 20 points. AIH and TTP are rare complications of SLE. The prevalence of the complication of SLE and AIH has been reported as 1.7 approximately 2.7%, and that of SLE and TTP as 1 approximately 4%. We reported here a rare case of SLE complicated with AIH and TTP.

Primary biliary cirrhosis-autoimmune hepatitis overlap syndrome concomitant with systemic sclerosis, immune thrombocytopenic purpura

A 58-year-old Japanese woman presented with chronic fluctuating liver dysfunction with purpura. Raynaud's phenomenon had been diagnosed 4 years previously. At the initial examination, skin biopsy showed limited cutaneous systemic sclerosis (SSc). Laboratory investigations revealed liver dysfunction. Anti-nuclear antibodies, anti-mitochondria M2 antibody, anti-thyroglobulin antibody, and platelet-associated IgG were positive. Primary biliary cirrhosis (PBC) and autoimmune hepatitis (AIH) were diagnosed serologically, clinically and histologically. Immune thrombocytopenic purpura (ITP) was diagnosed by bone marrow puncture, clinical and laboratory findings, and Helicobacter pylori IgG was positive. She was treated with prednisolone 30 mg/day, ursodeoxycholic acid 600 mg/day, and a 7-day course of lansoprazole plus amoxicillin and clarithromycin. Thrombocytes increased rapidly and transaminase improved at day 7. We report a rare case of PBC-AIH overlap syndrome with concurrent ITP and SSc which suggest the presence of shared genetic susceptibility factors in multiple autoimmune conditions including PBC, AIH, ITP and SSc.

Undifferentiated connective tissue diseases-related hepatic injury

Hepatic injury is rarely associated with undifferentiated connective tissue diseases (UCTD). We report, here, a case of a middle-aged woman with UCTD-related hepatic injury, including its case history, clinical manifestations, laboratory findings, treatment and its short-term effect. The patient was admitted to the hospital with symptoms of fatigue, anorexia, low-grade fever and skin rashes. She had a past history of left knee joint replacement. Laboratory tests showed elevated levels of serum transaminase, IgG and globulin, accelerated erythrocyte sedimentation rate, eosinophilia and a high titer of antinuclear antibodies (1:320). Imaging studies showed interstitial pneumonitis and hydropericardium. Liver biopsy showed the features which were consistent with those of connective tissue diseases-related polyangitis. After treatment with a low-dose of oral prednisone, both symptoms and laboratory findings were significantly improved. UCTD-related hepatic injury should be considered in the differential diagnosis of connective tissue diseases with abnormal liver function tests. Low-dose prednisone may effectively improve both symptoms and laboratory tests.

Often forgotten manifestations of systemic sclerosis

Many clinical manifestations of systemic sclerosis (scleroderma) often go unrecognized; yet they can cause significant morbidity and are challenging to manage. This article discusses osteolysis, avascular necrosis of the wrist, oral manifestations, erectile dysfunction, pharyngeal weakness, fecal incontinence, nonscleroderma renal disease, liver disease, thyroid disease, and neurological disease in the scleroderma patient.

Autoimmune hepatitis associated with pulmonary arterial hypertension

A 46-year-old woman presented with arthralgia. She had a history of fluctuating liver function impairment for 6 months. Laboratory investigations revealed elevated liver function test results, positive antinuclear antibodies and elevated serum IgG. The histological findings of a liver biopsy were interface hepatitis accompanied by plasmocytic infiltration with bridging fibrosis. There was no evidence of cirrhosis on pathological examination and no portal hypertension on endoscopic and radiographic studies. Autoimmune hepatitis was diagnosed, and treatment with prednisolone improved the liver dysfunction. After 6 months, she complained of dyspnea. Doppler echocardiography showed a dilated right ventricle, severe tricuspid insufficiency, and systolic pulmonary arterial pressure indicative of pulmonary arterial hypertension. We report this rare case of autoimmune hepatitis with pulmonary arterial hypertension.

An overlap syndrome involving autoimmune hepatitis and systemic lupus erythematosus in childhood

We report a 12 years old female patient with an overlap syndrome involving autoimmune hepatitis (AIH) and systemic lupus erythematosus (SLE). The patient presented with jaundice, hepatosplenomegaly, malaise, polyarthralgia, arthritis and butterfly rash on the face. Laboratory tests revealed severe liver dysfunction, Coombs positive hemolytic anemia and a positive ANA/anti-dsDNA test. Renal biopsy showed class IIA kidney disease, while liver biopsy showed chronic hepatitis with severe inflammatory activity. The patient satisfied the international criteria for both SLE and AIH. Clinical symptoms and laboratory findings of SLE improved with high dose treatment with corticosteroids and azathioprine, however, remission of the liver disease could not be achieved. Repeat biopsy of the liver after three years of therapy revealed ongoing chronic hepatitis with high level of inflammatory activity. The present case indicates that children with liver dysfunction and SLE should be investigated for AIH. There is much diagnostic and therapeutic dilemma in patients with AIH-SLE overlap syndrome.

Sarcoidosis accompanied by systemic lupus erythematosus and autoimmune hepatitis

A 52-year-old woman was admitted to our hospital for further examination of blurred vision, abnormal lung shadows and an elevated level of angiotensin-converting enzyme. Sarcoidosis was suspected, however, careful history taking revealed the existence of photosensitivity and polyarthralgia. Laboratory tests showed lymphocytopenia, liver dysfunction, hypergammaglobulinemia, and positive anti-nuclear, anti-double stranded DNA and anti-smooth muscle antibodies. Liver biopsy examination showed chronic active hepatitis. She was diagnosed with the triplex of sarcoidosis, systemic lupus erythematosus and autoimmune hepatitis. Marked improvement was noted after corticosteroid therapy.
