Immunoregulatory proteins and cytokines in the blood of patients with Graves’ disease

Maklakova T.P., Zorina V.N., Yanysheva A.V., Mezentseva E.V., Zorin N.A.


Background. Immunoregulatory proteins (alpha-2-macroglobulin, lactoferrin) actively participate in inflammatory and autoimmune processes, affect synthesis and transport of hormones and cytokines, and control cell proliferation and apoptosis. However, the role of these proteins in the pathogenesis of Graves’ disease (GD) is poorly understood. Objective — the study objective was to determine blood levels of alpha-2-macroglobulin (α2-MG), lactoferrin (LF), and cytokines (TNF-α, IL-6, IL-8, and IFN-γ) in GD. Material and methods. We determined blood levels of TSH, free T4, TSH receptor antibodies, TNF-α, IL-6, IL-8, IFN-γ, and LF by ELISA as well as α2-MG by quantitative rocket immunoelectrophoresis in 50 patients with decompensated and compensated (4―6 months and 1.5―2 years after treatment onset) GD and 25 healthy females (control group). Results. GD clinically manifested by body weight l in 84% of patients, sinus tachycardia in almost all patients, paroxysmal atrial fibrillation in 18% of cases, endocrine ophthalmopathy in 12% of patients, and neurological changes. In decompensated GD, there was a statistically significant increase in levels of IFN-γ, IL-6, and α2-MG and an especially significant increase in levels of IL-8 and LF. At 4―6 months after treatment onset, clinical manifestations were stopped in all patients, levels of IL-6 and α2-MG decreased, but the concentrations of TSH receptor antibodies (TSHR-Abs), IL-8, IFN-γ, and LF remained elevated. At 1.5―2 years, levels of the studied proteins and cytokines did not differ from those in the control group. Conclusion. An increase in blood levels of IL-8, LF, IL-6, and α2-MG in incident or recurrent GD and a decrease in the levels during treatment confirm involvement of immunoregulatory proteins in pathogenesis of the disease.

Matrix metalloproteinases-1, -13 and their tissue inhibitor-1 in endocrine ophthalmopathy

Taskina E.S., Kharintseva S.V.


Effective regeneration of damaged soft orbital tissues in Graves’ ophthalmopathy (GO) requires coordinated remodeling of the extracellular matrix. Matrix metalloproteinases (MMPs) play an important role in the synthesis and degradation homeostasis of extracellular matrix components in various physiological and pathological conditions. Their proteolytic activity is inhibited by tissue inhibitors of metalloproteinases (TIMP). The biochemical processes taking place in extraocular muscles and retrobulbar tissue fibrogenesis in GO are not fully understood. Aims — to assess some biochemical mechanisms of extraocular muscles and retrobulbar tissue fibrogenesis in GO patients. Material and methods. The study included 65 people (130 eyes) at the age of 43 (35–50) years. Three groups of subjects were formed: 32 patients with a moderate GO severity (clinical group), 18 patients with autoimmune thyroid pathology without GO (comparison group), and 15 healthy persons (control). The diagnosis was based on clinical, laboratory, and instrumental data. A comprehensive ophthalmologic examination and blood sampling for determination of MMP-1, -13, TIMP-1, sulfated glycosaminoglycans (sGAG) and antibodies to thyroid-stimulating hormone receptor (TSHRAbs) were conducted. The data were statistically processed using the program Statistica 10.0. Results. An elevated level of MMP-13, observed in all GO patients (p<0.05). For the active phase of GOP, the comparison with the control group showed a 3.5-fold increase in MMP-13 (<i>p</i><0.001) and 1.17-fold rise in TIMP-1 (p>0.05). Pulse glucocorticoid therapy reduced MMP-13 by 48.6% (<i>p</i><0.001), TIMP-1 by 2.7% (<i>p</i><0.001), and TSHRAbs — by 93% (p<0.001) compared with active GO, but these indicators were higher than the reference limits of control (<i>p</i>>0.05). In inactive GO, despite increased MMP-13, TIMP-1 decreased to the reference values (<i>p</i>=0.533). There were no significant differences in MMP-1 in groups of subjects (<i>p</i>=0.865). Conclusions. We have found imbalance between MMP-13 and TIMP-1 production in different activity phases of GO. Active GO is characterized by an increase in serum MMP-13 and TIMP-1. Dysregulation of intercellular matrix remodeling, possibly, underlies the development of extraocular muscles and retrobulbar tissue fibrosis in GO.

The medical aspect of using anabolic androgenic steroids in males attending gyms of Saint-Petersburg

Lykhonosov M.P., Babenko A.Y.


Background. Anabolic androgenic steroids (AASs) are often used by individuals engaged in physical recreational activity. AASs inhibit the hypothalamus-pituitary-gonad axis and can cause erectile dysfunction and reduced fertility. There is no data on the use of AASs in this category of people in the Russian Federation; therefore, a study exploring the rate and patterns of using steroids for non-medical purposes is topical. Aim — of this study was to investigate the rate and patterns of using AASs in males attending gyms in Saint Petersburg. Material and methods. We used individual anonymous postal survey of males attending gyms. We analyzed demographic and anthropometric data, information on the use of AASs, awareness of their side effects, used agents, patterns and duration of their use, and rehabilitation therapy. Results. Out of 1,815 sent questionnaires, we received back 762 ones. The criteria were met by 550 questionnaires. The mean age was 29.3±7.4 years. The use of AASs was reported by 30.4% of respondents. The main AAS (74.3%) consumers were males aged 22 to 35 years. The most popular drug was Testosterone Propionate (51.5%); the drug was often combined with Oxandrolone (19.7%). In 70.6% of cases, drugs were administered by injection or injection combined with tablet intake. The injectable testosterone dose ranged from 500 to 2,000 mg/week and above. The most common dose was 1,000 mg/week (23.9%). AAS administration for more than 1 year was reported in 16.1% of males. Anastrozole (55%), hCG (51.3%), Clomiphene (41.3%), and Tamoxifen (30.5%) were used during the recovery period. The main source of information on AASs, doses, and dosage patterns was the Internet (48.7%). A negative attitude towards AASs was found in 17.3% of respondents. The desire to receive qualified information about AASs and their impact on health was reported by 54.8% of the surveyed respondents. Conclusion. Almost every fourth gym visitor has experience in using AASs. These are males of an optimal reproductive age. The common pattern of using AASs is an aggressive steroid course followed by a recovery period. The list of used drugs and their doses indicate a significant pharmacological intervention and a high risk to health.

Avzaletdinova D.S., Sharipova L.F., Kochetova O.V., Morugova T.V., Mustafina O.E.


Type 2 diabetes mellitus (T2DM) is one of the most acute problems of the modern world. The disease is characterized by high ratio of micro- and macrovascular complications. T2DM is a multifactorial and polygenic disease, structure of hereditary predisposition to which may be population-specific. Aim — the analysis of allelic associations of adiponectin gene (<i>ADIPOQ, rs17366743</i>) with T2DM, its clinical and metabolic characteristics and complications in T2DM patients resident in the Republic of Bashkortostan. Material and methods. 3 PCR-based method of genotyping with polymorphic marker <i>rs17366743</i> of <i>ADIPOQ</i> gene in 433 T2DM patients and 428 healthy controls, residents of Bashkortostan. Results. The ratio of genotype CT and allele С was higher in T2DM patients compared with controls (15.7% vs. 6.8%; <i>p</i>=0.0002 and 7.8% vs. 3.4%; <i>p</i><0.0001, respectively). Genotype ТТ and allele Т were less frequent in T2DM than in healthy subjects (84.3 and 93,2%; <i>p</i>=0.0002; 92.2 and 96.6%, <i>p</i><0.0001, respectively). The association with the development of diabetic retinopathy and cataract was shown (<i>p</i>=0,044, <i>p</i>=0,008, respectively). Conclusions. Allele C and genotype CT are risk markers of T2DM (OR=2.43 and 2.56 respectively).

Sodium balance impairment in a child with severe traumatic brain injury

Aleksandrovich Y.S., Pshenisnov K.V., Ustinova A.S., Kopylov V.V., Aleksandrovich I.V., Gordeev V.I.


We report a case of cerebral salt-wasting syndrome in a 12-year-old boy with severe traumatic brain injury. The child developed refractory intracranial hypertension at the time of injury, which required decompressive craniectomy on the 7<sup>th</sup> day after injury. Infusion of hypertonic sodium chloride solutions performed at the intensive care unit resulted in hypernatremia on the 5<sup>th</sup> day and polyuria and hypovolemia on the 11<sup>th</sup> day, which was regarded as manifestations of central diabetes insipidus. Persistent hyponatremia developed on the 17<sup>th</sup> day after injury; on the next day, the therapy was supplemented with Fludrocortisone at a dose of 100 µg/day, followed by an increase in the dose to 150 µg/day, which had no significant effect. Fludrocortisone was discontinued on the 30<sup>th</sup> day of therapy, but it was re-used at a dose of 400 µg/day from the 54<sup>th</sup> day. During this treatment, polyuria gradually decreased to 4 to 5 l/day, and the plasma sodium concentration remained within the reference values. The dose of Fludrocortisone was increased to 600 µg/day since the 66th day. The child was transferred to a specialized department on the 67<sup>th</sup> day after injury. At the Department of Neurosurgery, the dose of Cortineff was gradually reduced starting with the 94<sup>th</sup> day and completely discontinued on the 122<sup>nd</sup> day after injury. On day 132<sup>th</sup> of the post-traumatic period, the patient was transferred to another hospital for rehabilitation therapy.

Incomplete Wolfram syndrome. Clinical case report

Dianov O.A., Lavrova E.A., Maltcev V.V., Oleynik D.A.


We describe clinical presentation of Wolfram syndrome and follow-up data in a child. Diagnostics of Wolfram syndrome takes time because clinical symptoms develop not at the time of disease manifestation, but usually several years later. The sequence of manifestations also varies. According to the literature, sensorineural hearing loss occurs in the 2<sup>nd</sup> decade, and bladder atony develops only by the 3<sup>rd</sup> decade. In the presented case, initial manifestations of bladder innervation disorders in the form of its dysfunction developed as early as the first year, and sensorineural hearing loss formed by the 4<sup>th</sup> year of the disease. As in other studies, the patient developed optic disc atrophy within the first year after diabetes onset. This clinical case confirms variability in the clinical symptoms of Wolfram syndrome. The sequence in which the disease picture develops (in this case, there was an incomplete form of syndrome — the absence of diabetes insipidus) does not always coincide with the classic course of syndrome, which complicates timely diagnosis.

Hypoglycemic syndrome in hepatic epithelioid hemangioendothelioma, successful treatment — liver transplantation from a living related donor

Bondar I.A., Chesnochenko L.I., Shabelnikova O.Y., Porshennikov I.A.


Hypoglycemic syndrome occurs not only in endocrine diseases but can complicate the course of many somatic diseases and tumors of pancreatic and extra-pancreatic localization. Development of hypoglycemia in liver tumors is associated with a decrease in the volume of functioning liver tissue, increased consumption, and utilization of glucose by the tumor tissue, inhibition of gluconeogenesis and glycogenolysis, and secretion of insulin-like peptides. Hypoglycemia in liver tumors is rarely the first symptom of the disease and usually occurs in patients with large tumor sizes and symptoms of tumor intoxication. Epithelioid hemangiendothelioma of the liver is the primary malignant neoplasm from the group of mesenchymal tumors, it occurs less than in 1% of cases of all malignant neoplasms of the liver. The clinical course of epithelioid hemangiendothelioma of the liver is highly variable. There are slowly and rapidly progressing variants. The diagnosis is based on the results of histological and immunohistochemical examination of the postoperative material. In the literature there is no description of hypoglycemia in epithelioid hemangiendothelioma. We report a patient with severe hypoglycemic syndrome, which was due to an epithelioid hemangioendothelioma of the liver. Pharmacological treatment of hypoglycemia was ineffective. The presence of massive bilobar tumor made it impossible to use a liver resection. Hepatectomy with living related liver transplantation was life-saving procedure and made it possible to eliminate hypoglycemia.

Prospects of intranasal insulin for correction of cognitive impairments, in particular those associated with diabetes mellitus

Surkova E.V., Derkach K.V., Bespalov A.I., Shpakov A.O.


Despite the well-studied effect of insulin in peripheral tissues, its role in functioning of the central nervous system is much less understood. The effects of insulin in the brain are extremely diverse: insulin plays an important role in neuron growth and differentiation, affects higher cognitive functions (in particular, the formation of long-term memory), and also has a neuroprotective effect. Both peripheral and central insulin resistance as well as absolute insulin deficiency impairs the functional activity of neurons and neurogenesis. Several studies have investigated intranasal administration of insulin as a potential way for correction of these disorders. The review presents data on abnormalities of the insulin signaling system in the brain in diabetes mellitus, which is accompanied by cognitive dysfunction of varying severity and is associated with the development of neurodegenerative disorders, including Alzheimer’s disease. We analyzed the results of studies on the use of intranasal insulin in animal models with diabetes mellitus, healthy volunteers, and patients with cognitive impairments.
