Eighty-two consecutive patients with moderate-to-severe and active Graves' ophthalmopathy were randomly treated with orbital radiotherapy combined with either oral (prednisone; starting dose, 100 mg/d; withdrawal after 5 months) or iv (methylprednisolone; 15 mg/kg for four cycles and then 7.5 mg/kg for four cycles; each cycle consisted of two infusions on alternate days at 2-wk intervals) glucocorticoids. The two groups did not differ for age, gender, duration of hyperthyroidism and ophthalmopathy, prevalence of smokers, thyroid volume, and pretreatment ocular conditions. Both groups of patients received radioiodine therapy shortly before treatment for Graves' ophthalmopathy. Follow-up lasted for 12 months. A significant reduction in proptosis (from 23.2 +/- 3.0 to 21.6 +/- 1.2 mm in the iv glucocorticoid group, P < 0.0001; and from 23 +/- 1.8 to 21.7 +/- 1.8 mm in oral glucocorticoid group, P < 0.0001) and in lid width (from 13.3 +/- 2.5 to 11.8 +/- 2.2 mm, and from 13.6 +/- 2.0 to 11.5 +/- 1.9 mm, respectively; P < 0.001 in both cases) occurred, with no difference between the two groups. Diplopia significantly improved in both groups: it disappeared in 13 of 27 (48.1%) iv glucocorticoid patients (P < 0.005) and in 12 of 33 (36.4%) oral glucocorticoid patients (P < 0.03). The degree of amelioration of diplopia did not significantly differ between the two groups (P = 0.82). Optic neuropathy improved in 11 of 14 iv glucocorticoid (P < 0.01) and only in 3 of 9 oral glucocorticoid (P = 0.57) patients, with no significant difference in these outcomes. The Clinical Activity Score decreased from 4.5 +/- 1.2 to 1.7 +/- 1.0 (P < 0.0001) in the iv glucocorticoid group and from 4.2 +/- 1.1 to 2.2 +/- 1.2 (P < 0.0001) in the oral glucocorticoid group; final Clinical Activity Score was significantly lower in iv glucocorticoid than in oral glucocorticoid patients (P < 0.01). By self-assessment evaluation, 35 (85.3%) iv glucocorticoid and 30 (73.2%) oral glucocorticoid patients reported an improvement of ocular conditions (P = 0.27). Overall, both treatments produced favorable effects in most patients, but responders in the iv glucocorticoid group (36 of 41, 87.8%) were more than in the oral glucocorticoid group (26 of 41, 63.4%) (P < 0.02). Moreover, iv glucocorticoid treatment was better tolerated than oral glucocorticoid treatment. Side effects occurred in 23 (56.1%) iv glucocorticoid and 35 (85.4%) oral glucocorticoid patients (P < 0.01); in particular, cushingoid features developed in 5 of the former and 35 of the latter patients. One iv glucocorticoid patient had severe hepatitis of undetermined origin at the end of glucocorticoid treatment, followed by spontaneous recovery. In conclusion, high-dose iv glucocorticoid and oral glucocorticoid (associated with orbital radiotherapy) are effective in the management of severe Graves' ophthalmopathy, but the iv route seems to be more effective and better tolerated than the oral route and associated with a lower rate of side effects.

Harderian gland neoplasms were identified in 18 aged, adult Beechey ground squirrels (Spermophilus beecheyi) from the records of 167 wild-caught captive animals that were necropsied. All but one animal had tumors that were classified as carcinomas, with infiltrative growth and frequent metastases. This is the first detailed report of Harderian gland neoplasia in wild Sciuridae, although this neoplasm has been described in other rodent species. Clinically, affected ground squirrels typically were inappetent and presented with weight loss and exophthalmos. The biologic behavior of Harderian gland neoplasia is variable among rodent species; in Beechey ground squirrels there was a high incidence of malignant behavior. Eleven of 17 tumor-bearing animals for which the gender was known were male, and 6 were female. Nine of 16 for which data were available were uninfected, and 7 had evidence of current or prior infection with ground squirrel hepatitis virus. Tumor development occurred in older animals; all but 2 were 5.5 years of age or older. The presence of metastasis was not related to gender or chronic ground squirrel hepatitis virus infection.

We report a case of hepatotoxicity induced by methimazole treatment in a patient affected by hyperthyroidism. A 54-year-old man, presented to our observation for palpitations, excessive sweating, weakness, heat intolerance and weight loss. On physical examination, his blood pressure was 140/90 mmHg and heart beat was 100/min regular. He had mild tremors and left exophthalmos. Laboratory test revealed a significant increase in serum thyroid hormone levels with a decrease in thyroid stimulating hormone levels. A diagnosis of hyperthyroidism was made and he began treatment with methimazole (30 mg/day). Fourteen days later, he returned for the development of scleral icterus, followed by dark urine, and abdominal pain in the right upper quadrant. Laboratory examinations and liver biopsy performed a diagnosis of cholestatic hepatitis, secondary to methimazole usage. Methimazole was promptly withdrawn and cholestyramine, ursodeoxycholic acid, and chlorpheniramine were given. After five days, abdominal pain resolved and laboratory parameters returned to normal. Naranjo probability scale indicated a probable relationship between hepatotoxicity and methimazole therapy. In conclusion physicians should be aware the risk of hepatotoxicity related with methimazole.

Pediatric intractable autoimmune hepatitis is rare and may be responsible for acute liver failure. Mutations in the itchy E3 ubiquitin protein ligase (ITCH) gene (located on chromosome 20q11.22) can lead to a deficiency of the encoded protein, resulting in increased T-cell activity with lack of immune tolerance and manifestation of a complex systemic autoimmune disease. A 1-year-old girl of consanguineous parents received a liver transplant (LT) because of acute liver failure attributed to a drug-induced hypereosinophilic syndrome with positive liver-kidney-mikrosome-2 antibodies. Notable findings were syndromic features, dystrophy, short stature, psychomotor retardation, and muscular hypotonia. Later, we saw corticosteroid-sensitive rejections as well as a systemic autoimmune disease with detection of specific antibodies (de novo autoimmune hepatitis, thyroiditis with exophthalmos, diabetes mellitus type 1, and immune neutropenia). Histologically, liver cirrhosis with lobular inflammatory infiltrates, giant-cell hepatitis, and ductopenia was verified in chronic cholestasis. Shortly after a second LT, a comparable liver histology could be detected, and viral, bacterial, and mycotic infections deteriorated the general health condition. Because of refractory pancytopenia related to portal hypertension and hypersplenism, a posttransplant lymphoproliferative disorder was excluded. One year after the second LT, epidural and subdural bleeding occurred. Three months afterward, the girl died of sepsis. Postmortem, whole-exome sequencing revealed a homozygous mutation in the ITCH gene. A biallelic mutation in ITCH can cause a severe syndromic multisystem autoimmune disease with the above phenotypic characteristics and acute liver failure because of autoimmune hepatitis. This case reveals the importance of ubiquitin pathways for regulation of the immune system.
