Donohue syndrome (DS), also called Leprechaunism, is the most severe form of insulin resistance associated with biallelic mutations in INSR gene (OMIM: 147670). The approximate incidence of this syndrome is 1 per 1000000 births. Patients are present with typical clinical features such as intrauterine growth retardation, facial dysmorphism, severe metabolic disturbances, hepatomegaly and hypertrophic cardiomyopathy. Most DS patients die within the first two years of life due to respiratory infections, severe hypoglycemia or progressive cardiomyopathy. Treatment options are limited and no specific therapy exist for DS. Given the similarities between insulin and insulin-like growth factor 1 (IGF-1) receptors, recombinant human IGF-1 (rhIGF-1) has been used to treat severe insulin resistance including DS.We report the case of a male patient with genetically confirmed Donohue syndrome, successfully treated with continuous subcutaneous IGF1 infusion via insulin pump. We observed improvement of glycemic control, liver function and cardiac hypertrophy regression following 15-month IGF1 therapy.

This article presents a literature review of the various forms of hypophysitis, its varieties, as well as the problem of radiation diagnosis and treatment of this pathology. Hypophysitis is a poorly understood and multifactorial disease which the difficulty of diagnosing is not only to a variety of nonspecific clinical manifestations and hormonal research data, but also the ambiguous results of MRI studies, the lack of clear MR patterns. The article reflects the main histological types of hypophysitis, the peculiarities of diagnosis in connection with general clinical symptoms, outlines the features of each type of hypophysitis with their own clinical observations. This review is devoted to modern ideas about the clinical course of hypophysitis, presented a set of characteristic diagnostic signs of the disease according to MRI and the treatment algorithms recommended today are also highlighted. The article summarizes data from foreign literature and our own clinical observations in order to develop an optimal protocol for MRI studies in patients with suspected hypophysitis, to develop recommendations for radiologists and endocrinologists for the correct results interpretation. The uniqueness of this review is the lack of data on the clinic, diagnosis and treatment of hypophysitis in the Russian literature today.
