Background: Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant cancer syndrome characterized by the occurrence of primary hyperparathyroidism (PHPT), pituitary adenoma (PA) and pancreatic neuroendocrine tumor (pNET). Whether the underlying mutations in MEN1 gene predict clinical presentation of affected heterozygotes or not, is still a matter of a debate. Methods: Clinical and genetic analysis of 90 consecutive MEN1 patients was performed in a retrospective, single - center study. Results: MEN1 mutation was found in 67 (74.4%) patients belonging to 31 different families. Twenty nine different heteozygous mutations were found, including 6 novel point mutations (W220G, 941delG, 1088del7, 1184insA, 1473del10, 1602del17) and one large deletion of exon 8. Truncating mutations predicted development of pNETs (OR=5.8, 95% CI 1.7 - 19.7%) and PHPT (OR=4.3, 95% CI 1.5 - 12.4%). Conclusions: Large number of novel mutations among MEN1 patients confirmed previously reported data. PNETs and PHPT were more frequent in patients with truncating mutations. © 2019 Tatjana Isailovic et al., published by Sciendo 2019.

Introduction: Although numerous studies indicated a link between antithyroid antibodies and recurrent spontaneous abortions (RSA), consensus on the treatment of this condition is still lacking. Case report: We present a case of a 35-year-old pregnant woman (gestation week 4) with primary hypothyroidism, total alopecia, high level of positive antithyroid antibodies, and history of two recurrent spontaneous abortions in early pregnancy. Along with L-thyroxin substitution, intravenous human immunoglobulin (IVIg) combined with anticoagulation and antiaggregation therapy was introduced. During pregnancy her scalp hair completely re-grew, and following gestation week 39 she delivered healthy female child. Conclusion: Thyroid antibodies could contribute to previous recurrent abortions in our patient. It is suggested that in older primiparas with Hashimoto thyroiditis and history of RSA, a combined treatment with IVIg, anticoagulation and antiaggregation therapy should be considered. © 2014 Informa UK Ltd.
