Therapeutic plasma exchange (TPE) is one possible treatment for patients resistant to conventional antithyroid drugs or requiring urgent attention for thyrotoxicosis. We report a 35-yr-old man with thyrotoxicosis, ultimately attributed to Graves' disease in whom antithyroid drug used initially was soon discontinued, due to abnormal liver function, and replaced by Lugol's solution. Three weeks later, an escape phenomenon (to Lugol's solution) was apparent, so we performed TPE to control the thyrotoxicosis. Two courses of TPE by a centrifugal type machine resulted in diminished levels of thyroid hormone levels, which then rebounded after another two courses of membrane filtration type TPE. However, the patient could be treated with radioactive iodine therapy without any complications at present.

OBJECTIVETo observe the therapeutic effect of Xiehuo Yangyin powder (XHYY) in treating the initial stage of toxic and diffuse goiter (Graves' disease).

METHODSSixty patients were randomly divided into two groups, the treated group (n = 30) was treated with XHYY and methimazole, while the control group (n = 30) was treated with methimazole alone. The TCM syndrome score and thyroxin level in the two groups were compared and analyzed before, and 2 weeks, 12 weeks after treatment.

RESULTSThe syndrome score and thyroxin level in the treated group 2 weeks, 4 weeks, 12 weeks after treatment were reduced in comparing with before treatment, with the improvement better than those in the control group in the corresponding stages (P < 0.05).

CONCLUSIONThe Chinese herbal medicine XHYY plus methimazole, in treating Graves' disease, could rapidly and effectively improve the patients' clinical symptoms and lower the thyroxin level, reduce the daily taken of methimazole.

Methimazole and propylthiouracil have been used in the management of hyperthyroidism for more than half a century. However, hepatotoxicity is one of the most deleterious side effects associated with these medications. The mechanism(s) of hepatic injury induced by antithyroid agents is not fully recognized yet. Furthermore, there are no specific tools for predicting the occurrence of hepatotoxicity induced by these drugs. The purpose of this article is to give an overview on possible susceptibility factors in liver injury induced by antithyroid agents. Age, gender, metabolism characteristics, alcohol consumption, underlying diseases, immunologic mechanisms, and drug interactions are involved in enhancing antithyroid drugs-induced hepatic damage. An outline on the clinically used treatments for antithyroid drugs-induced hepatotoxicity and the potential therapeutic strategies found to be effective against this complication are also discussed.

Bullous systemic lupus erythematosus (SLE) is a kind of LE-non-specific bullous skin disease that is rarely induced by a medication. We describe the first case of bullous SLE to develop after administration of methimazole. A 31-yr-old woman presented with generalized erythematous patches, multiple bullae, arthralgia, fever, conjunctivitis, and hemolytic anemia. Biopsy of her bulla showed linear deposition of lgG, lgA, C3, fibrinogen, and C1q at dermo-epidermal junction. She was diagnosed as bullous SLE and treated with prednisolone, dapsone, hydroxychloroquine, and methotrexate. Our experience suggests that SLE should be considered as a differential diagnosis when bullous skin lesions develop in patients being treated for hyperthyroidism.

OBJECTIVEPropylthiouracil (PTU) as a drug used during the treatment of hyperthyroidism could induce antineutrophil cytoplasmic autoantibody-positive vasculitis. Here the author reported a childhood case of antineutrophil cytoplasmic autoantibody-positive vasculitis induced by PTU, which is rarely described.

METHODSThe diagnosis was made according to the symptoms, signs, serum markers and renal biopsy, and the relevant literature was reviewed.

RESULTSThe 12-year-old girl presented with gross hematuria, proteinuria, renal function damage [Ccr 52.46 ml/(min. 1.73 m(2))], positive antineutrophil cytoplasmic autoantibody (ANCA-MPO) (MPO ELISA 140%) and a vasculitis lesion in the renal biopsy sample. She had been treated with PTU for 5 years because of Graves disease. After the diagnosis, the PTU was withdrawn, and prednisone (40 mg/d) and cyclophosphamide (25 mg, Bid) were applied. Three weeks after the therapy with prednisone and cyclophosphamide the gross hematuria disappeared. Three months after the treatment the renal function returned to normal [Ccr 124 mg/(min.1.73 m(2))], and the titer of ANCA-MPO decreased from 140% to 57%.

CONCLUSIONPTU may induce antineutrophil cytoplasmic autoantibody positive vasculitis. A right diagnosis and treatment can improve its prognosis of the disease.

OBJECTIVETo study the relationship between methimazole (MMI) and antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis.

METHODSThirty-three cases with Graves' disease were tested for serum ANCA before and after taking MMI. At the same time, clinicopathological data of two patients with Graves' disease who had antineutrophil cytoplasmic antibody-positive vasculitis during treatment with MMI were analyzed.

RESULTSTwo patients developed antineutrophil cytoplasmic antibody-positive vasculitis during the medication with MMI for 5-6 years; their major clinical manifestations were hematuria and renal failure. Renal biology showed renal vasculitis and vascular necrosis. The disease was relieved after treatment with immunosuppressor. Serum ANCA in the 33 cases was negative before taking MMI. In 3 cases serum ANCA became positive after taking MMI for 2 months, 3 months and 2 years, respectively. The positive rate is 9% (3/33). The major finding was microscopic hematuria. ANCA positive rate was significantly higher after taking MMI than that before taking MMI (chi2) = 5.3, P < 0.05). Microscopic hematuria disappeared after general treatment.

CONCLUSIONThere may be a relationship between methimazole and development of antineutrophil cytoplasmic antibody-positive vasculitis. Renal impairment can occur. The signs and symptoms of the vasculitis can disappear after proper treatment.

Both Graves disease and Guillain-Barre syndrome (GBS) are autoimmune disorders caused by impaired self-tolerance mechanisms and triggered by interactions between genetic and environmental factors. GBS in patients who suffer from other autoimmune diseases is rarely reported, and the development of postinfectious GBS in a patient with Graves disease has not been previously reported in the literature. Herein, we report a patient with Graves disease who developed postinfectious GBS during a course of methimazole-induced agranulocytosis.
