Multiple sclerosis, interferon beta and clinical thyroid dysfunction.

The objective of this study was to investigate frequency and presentation of clinical thyroid dysfunction in patients treated with interferon beta (IFN-beta). We have collected the cases of clinical thyroid dysfunction in 700 consecutive patients receiving IFN-beta for multiple sclerosis (MS). Five patients (four women, one man) treated with IFN-beta1b developed hyperthyroidism. Three of them have secondary progressive MS, and two have relapsing-remitting MS. It was necessary to stop IFN-beta in three cases; these patients still require carbimazole after several months. In the two other cases, hyperthyroidism disappeared spontaneously. Two patients (one man and one woman) treated with IFN-beta1a developed hypothyroidism. One of them required l-thyroxine. Lastly, an increased thyroid volume without modification of thyroid hormones plasma levels was discovered in a patient receiving IFN-beta1a. Among patients treated with IFN-beta, clinical thyroid dysfunction is much rarer than laboratory thyroid dysfunction. However, this side-effect is sometimes severe.

[Posttraumatic neurogenic hyponatremia with late onset].

Ten months following a severe head injury, a 26-year-old man developed a syndrome of inappropriate secretion of antidiuretic hormone (ADH) with a grand mal seizure occurring after an increased intake of non alcoholic beverages. The water loading test was negative but the sorbitol infusion test was positive. In the basal state, plasma concentration of ADH was inappropriate to plasma osmolality. ADH has also been measured during dynamic tests (infusions of sorbitol and of normal saline; complete and partial water restriction; propranolol and diphenylhydantoin treatments). In spite of the poor sensitivity of these measurements when ADH concentrations are low, our results indicate that the plasma osmolality threshold at which ADH secretion is inhibited was probably reset at a level lower than normal.
