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.

Interferon-induced thyroiditis (IIT) is a major clinical problem for patients receiving interferon-alpha (IFN-alpha) therapy. But, destructive thyroiditis followed by Graves' disease associated with IFN-alpha therapy is very rarely reported. Herein, we report a rare case of pegylated IFN-alpha (pegIFN-alpha) induced destructive thyroiditis followed by Graves' disease in a patient with HCV infection. A 31-yr-old woman suffered from chronic active hepatitis C and was treated with pegIFN-alpha and ribavirin for 12 months. Results of a thyroid function test and autoantibody levels were normal before IFN-alpha therapy was initiated. Destructive thyrotoxicosis appeared seven months after the initiation of IFN-alpha therapy, followed by Graves' thyrotoxicosis two months after the cessation of therapy. The diagnoses of destructive thyroiditis and Graves' disease were confirmed by the presence of TSH receptor antibodies in addition to Tc-99m scintigraphy findings. The patient's antithyroglobulin antibody titer increased gradually during IFN-alpha therapy and remained weakly positive after IFN-alpha therapy was discontinued.

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.

Hyperglycemic hyperosmolar state (HHS) is an acute complication mostly occurring in elderly type 2 diabetes mellitus (DM). Thyrotoxicosis causes dramatic increase of glycogen degradation and/or gluconeogenesis and enhances breakdown of triglyc-erides. Thus, in general, it augments glucose intolerance in diabetic patients. A 23-yr-old female patient with Graves' disease and type 2 DM, complying with methimazole and insulin injection, had symptoms of nausea, polyuria and generalized weakness. Her serum glucose and osmolarity were 32.7 mM/L, and 321 mosm/kg, respectively. Thyroid function tests revealed that she had more aggravated hyperthyroid status; 0.01 mU/L TSH and 2.78 pM/L free T3 (reference range, 0.17-4.05, 0.31-0.62, respectively) than when she was discharged two weeks before (0.12 mU/L TSH and 1.41 pM/L free T3). Being diagnosed as HHS and refractory Graves' hyperthyroidism, she was treated successfully with intravenous fluids, insulin and high doses of methimazole (90 mg daily). Here, we described the case of a woman with Graves' disease and type 2 DM developing to HHS.

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.

OBJECTIVETo study the effects of Radix Astragali on serum cytokines IL-1beta, TNFalpha and antigen expression of peripheral blood mononuclear cells (PBMCs) in patients with Graves disease (GD).

METHODSEighty GD patients at their first visit were randomly assigned to the methimazole (MMI) group (Group A) and the MMI combined Radix Astragali group (Group B), 40 in each. The improvement of clinical symptoms and thyroid functions were observed after one-month treatment. The serum IL-1beta and TNF-alpha levels in the peripheral blood were determined using radioimmunoassay. The expression levels of surface antigen CD80, CD54, and HLA-DR of PBMCs were detected using flow cytometry.

RESULTSThe improvement of the thyroid gland function was similar in the two groups. There was no obvious change in the levels of autoantibody TGAb or TPOAb of the two groups. Symptoms such as fear of heat, hidrosis, palpitation, and so on were more obviously improved in Group B than in Group A (P < 0.05). The serum IL-betaP, TNFalphaa, CD00 levels in the peripheral blood were all improved in the two groups after treatment when compared with before treatment ( P < 0.05 or P < 0.01). But the serum levels of IL-beta and TNFalpha decreased more obviously in Group B than in Group A ( P < 0.05). The expression of CD54 decreased more obviously in Group B (P < 0.01), showing statistical difference when compared with Group A at the same time point (P < 0.05).

CONCLUSIONRadix Astragali could significantly relieve the clinical symptoms such as hidrosis and palpitation, regulate the immune function of GD patients, playing an important role in the adjuvant therapy for GD.

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.

OBJECTIVETo observe the improvement of thyroid function and changes of Akt, p-Akt, mammalian target of rapamycin (mTOR), and para-mTOR (p-mTOR) expression in Graves' disease (GD) mice after intervened by Jiakangning Capsule (JC), and to explore possible mechanism for JC in treating GD.

METHODSGD model was established by immunizing female BALB/c mice with thyroid stimulating hormone receptor A subunit (Ad-TSHRα-289). Totally 70 successfully modeled mice were divided into the model group (n =20), the JC intervened group (n =25), the Methimazole Tablet intervened group (n =25) according to random digit table. A normal control group (n =15) and a vehicle control group (n =20, injected with Ad-null) were also set up. Mice in the JC intervened group were administered with JC suspension at the daily dose of 1. 5 g/kg by gastrogavag. Mice in the Methimazole intervened group were administered with Methimazole suspension at the daily dose of 2. 5 g/kg by gastrogavage. Equal volume of normal saline was administered to mice in the rest 3 groups by gastrogavage. All intervention lasted for 5 weeks. Six mice were selected from each group to observe pathological changes of thyroid tissues. Serum levels of thyroxine (T4), triiodothyronine (T3), thyroid stimulating hormone (TSH), and thyrotropin receptor antibody (TRAb) were analyzed by radioimmunoassay. Expression levels of Akt, p-Akt, mTOR, and p-mTOR in thyroid tissues were etermined by Western blot.

RESULTS(1) The thyroid gland in the GD model group showed proliferative changes, with enlarged follicles of various sizes. Interstitial stroma was filled with blood vessels. Structures of thyroid tissues in the JC intervened group and the Methimazole intervened group were significantly restored, and follicular hyperplasia was relieved. (2) Compared with the normal control group and the vehicle control group, levels of TRAb, T4, and T3 increased; ratios of P-Akt/β-actin, p-Akt/Akt, p-mTOR/β-actin, and p-mTOR/mTOR also increased in the model group (all P <0. 01). Compared with the model group, levels of TRAb, T4, and T3 decreased in the JC intervened group and the Methimazole intervened group (P <0. 01); ratios of p-mTOR/β-actin and pmTOR/mTOR decreased in the JC intervened group (P <0.01); ratios of P-Akt/β-actin, p-Akt/Akt, p-mTOR/β-actin, and p-mTOR/mTOR decreased in the Methimazole intervened group (P <0. 05, P <0. 01). Conclusion JC could reduce thyroid hormonc levels of GD mice and lower expression levels of mTOR, and its mechanism for improving thyroid function of GD mice might be associated with this influence.
