methimazole and Diarrhea

A case of Basedow's disease, that developed after successful treatment of ulcerative colitis with a total colectomy, is presented, along with a review of the Japanese literature on the coexistence of hyperthyroidism and ulcerative colitis. A 26-year-old man was referred to our department, complaining of general fatigue, appetite loss, and palpitation. At age 14, blood was discovered in his stool and a diagnosis of ulcerative colitis was made. Since then, he has been treated with salazosulfapyridine and prednisolone. On examination, mild exophthalmos and thyroid swelling were observed. Both serum free T3 and T4 levels were increased along with a positive TSH receptor antibody, while TSH was decreased. Scintigraphic and ultrasonographic examinations of the thyroid gland showed diffuse enlargement. Treatment with thiamazole relieved the symptoms and normalized the thyroid function. Although a high incidence of autoimmune thyroid diseases in association with ulcerative colitis has been suggested, only 6 cases of hyperthyroidism coexisting with ulcerative colitis have been reported in Japan. A common immunological process has been suggested to be implicated in the pathogenesis of this association, however, the exact mechanism remains unclear.

A 56-year-old woman with Graves' disease presented with the complaints of diarrhea and palpitations. Physical examination and laboratory data revealed hypothermia and signs of mild hyperthyroidism, heart failure, hepatic dysfunction with jaundice, hypoglycemia, and lactic acidosis. The patient was diagnosed as having developed the complication of thyroid storm in the absence of marked elevation of the thyroid hormone levels, because of the potential hepatic and cardiac dysfunctions caused by heavy alcohol drinking. A year later, after successful treatment, the patient remains well without any clinical evidence of heart failure or hepatic dysfunction. Thyroid storm associated with lactic acidosis and hypothermia is a serious condition and has rarely been reported. Prompt treatment is essential even if the serum thyroid hormone levels are not markedly elevated. We present a report about this patient, as her life could eventually be saved.

A 54-years-old patient coming from Guinea, who presented fever, diarrhoea, consciousness disorders and severe haemolytic anaemia, was admitted to resuscitation unit in France. Despite many explorations carried out (evaluation of traumatic causes, infection, neoplasia, vascular, toxic causes, vitamin deficiency), it was not possible to explain neurological symptomatology. Besides, haemolytic anaemia was due to the ingestion of metamizole in a context of glucose-6-phosphate dehydrogenase deficit. This drug's marketing has been suspended in France since 2006. Despite appropriate treatment, after seven days of hospitalization, the patient died of multi-organ failure and hemophagocytic syndrome. This clinical case illustrates the difficulties encountered to set a diagnosis and manage patients coming from overseas. Uncommon aetiologies for French healthcare professionals should be evoked in the absence of comprehensive clinical information.

A 50-year-old woman was admitted to our hospital because of severe diarrhea, irritableness, and severe pitting edema of the legs. The patient had been well until 5 years before admission, when a tremor and tachycardia developed and a diagnosis of Graves' disease was made. Treatment with methimazole was effective in reducing her tremor and tachycardia; however, she was often nonadherent with her antithyroid medication because of improvement of her symptoms. On admission, a thyroid swelling, exophthalmos, a pleural effusion, and ascites were observed. The results of thyroid function tests (free triiodothyronine: 21.5 pg/mL; free thyroxine: 7.17 ng/dL; thyroid-stimulating hormone (TSH): <0.01 microIU/mL; TSH receptor antibodies: 95.9%) were consistent with Graves' disease. Biochemical analysis of pleural and ascitic fluid was consistent with chylothorax and chylous ascites, respectively. Serum calcium, total protein, and albumin were very low. Her symptoms and signs except severe diarrhea, edema, pleural effusion, and ascites disappeared after receiving intravenous drip infusion of fluid replacement, and methimazole and iodine. Because of malnutrition, she was given a high-calorie intravenous infusion. Three months after admission, her pleural effusion and ascites began to improve, as did her diarrhea and hypoalbuminemia. An appropriate treatment of Graves' disease is crucial to avoid serious sequelae of longstanding, poorly controlled hyperthyroidism.

We recently observed 2 lactase-deficient women with Graves' disease who consistently developed severe diarrhea after ingestion of thionamide (methimazole and propylthiouracil) tablets containing lactose as carrier. The strict temporal relationship between ingestion of lactose-containing tablets and appearance of intestinal symptoms, as well as the absence of side effects following ingestion of methimazole tablets without lactose as carrier, provided the clue for the diagnosis. To our knowledge, severe diarrhea resulting from carrier lactose has not been previously reported for antithyroid drugs, and should be considered in occasional cases of patients with gastrointestinal symptoms on thionamide therapy.

A 19-year-old man had mild diarrhoea at the time that suddenly one night he was unable to turn in his bed and the following morning could not move his arms and legs for 4 hours. Neither he nor any family members had previously had any paralysis. Physical examination was unremarkable except for mild tachycardia and first-degree goitre.. A provocation test with glucose (3 g/kg) and insulin (0.1 IU/kg) caused renewed paralysis for several hours, serum potassium falling from 4.3 to 3.4 mmol/l. The paralysis was reversed on oral potassium (40 mmol) Thyroid function tests revealed hyperthyroidism with an increased concentration of free thyroxine (25.5 pg/ml) and free triiodothyronine (9.7 pg/ml), while thyroid-stimulating hormone was decreased (0.07 mU/I), supporting the diagnosis of autoimmune thyroiditis.. Thyrostatic treatment was started with thiamazole (10 mg every other day). There was no further periodic paralysis and another provocation test was negative.. Fleeting paralysis is often misdiagnosed as being psychogenic. Potassium abnormalities are the most common cause but are only rarely associated with hyperthyroidism. This case of thyrotoxic hypokalaemic paralysis was probably based on a genetic defect of muscle fibre membrane manifesting itself only in the presence of hyperthyroidism.
