The clinical and laboratory features of 29 patients who had one of three anti-aminoacyl-tRNA synthetase autoantibodies, anti-Jo1 (histidyl-tRNA synthetase), anti-PL12 (alanyl-tRNA synthetase) or anti-PL7 (threonyl-tRNA synthetase) were analysed and compared with the findings of other published reports. These autoantibodies were found to be associated with a syndrome delineated by inflammatory myositis (24 patients) and pulmonary fibrosis (23 of 29), but also including inflammatory arthritis (26/29), keratoconjunctivitis sicca (17/29), sclerodactyly (21/29), Raynaud's phenomenon (27/29), hepatitis (8/29) and subcutaneous calcinosis (7/29). The most important clinical determinant of outcome in this group of patients was the severity of the interstitial pulmonary disease. No patient fulfilled the classification criteria for systemic lupus erythematosus, although 10 had autoantibodies to extractable nuclear antigens including Ro, La, RNP, and Sm, and two patients had anti-dsDNA antibodies. Although it seems unlikely that anti-aminoacyl-tRNA synthetase antibodies are directly responsible for causing disease, they may provide an important clue to the aetiology of this unusual syndrome.

A case of Raynaud's phenomenon, was complicated with autoimmune hepatitis (AIH) during the clinical course, and subsequently with gangrene of the fingertips caused by CRST syndrome (calcinosis cutis, Raynaud's phenomenon, sclerodactyly and telangiectasia). The presence of anticentromere antibodies is rare in AIH; to date, there has been only one report of a combination of AIH and CRST syndrome. This combination of the two diseases has been identified only in Japan.

A 46-year-old woman presented with chronic fluctuated liver function impairment, Raynaud's phenomenon, digital gangrene, pulmonary hypertension, and intense pruritus within a period of 2 years. Laboratory investigations revealed antinuclear antibodies, anticentromere antibodies (ACA), hypergammaglobulinemia, lymphocytic infiltration of the liver parenchyma, and mild cholangitis. The associated symptoms included thyroiditis, conjunctivitis sicca, xerostomia, and polyarthralgia. There was no conspicuous sclerodactyly, calcinosis, or dysphagia. The symptoms were relieved with intravenous, as well as oral, methylprednisolone. This constellation of presentations, including chronic autoimmune hepatitis with mild cholangitis and pulmonary hypertension, suggested that the presence of serum ACA might indicate relentless visceral organ damage.

Systemic sclerosis (SSc) is a chronic systemic disease that affects the skin, lungs, heart, gastrointestinal tract, kidneys, and musculoskeletal system. Although up to 90% of patients with scleroderma have been estimated to have gastrointestinal involvement, liver disease has been reported only rarely. A 51-year-old woman was hospitalized due to esophageal variceal bleeding. Her serum was positive for anti-nuclear antibody and anti-centromere antibody. Sclerodactyly was noted on both hands, and she had recently developed Raynaud's syndrome. Punch biopsy of the hand showed hyperkeratosis, regular acanthosis, and increased basal pigmentation in the epidermis, and thick pale collagenous bundles in the dermis. Liver biopsy showed chronic active hepatitis with bridging fibrosis. Consequently, she was diagnosed with liver cirrhosis due to autoimmune hepatitis (AIH) combined with SSc. AIH had subsided after administration of prednisolone at 40 mg per day. She received 5-10 mg/day of prednisolone as an outpatient, and her condition has remained stable. Patients with either AIH or SSc should be monitored for further development of concurrent autoimmune diseases. The early diagnosis of AIH combined with SSc will be helpful in achieving optimal management.

A 55-year-old woman was admitted to our hospital with acute hepatitis of unknown origin. She had a history of incomplete-type CREST (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) syndrome and chronic thyroiditis approximately 10 years earlier. Although she achieved spontaneous remission without treatment, she was re-admitted 18 months later due to recurrent liver dysfunction. Liver biopsy was performed as we strongly suspected autoimmune hepatitis despite her normal serum immunoglobulin G level. Liver biopsy findings were histologically compatible with autoimmune hepatitis, and administering prednisolone (30 mg/day) led to a prompt recovery of her liver dysfunction. No relapse occurred during the tapering of prednisolone to a maintenance dose of 5 mg/day. Here we report a rare case of autoimmune hepatitis in a patient with a history of incomplete-type CREST syndrome and chronic thyroiditis.
