Background: Premature ovarian failure (POF) due to cyclophosphamide (Cyc) therapy is well documented in systemic lupus erythematosus (SLE) patients. Studies show that the use of gonadotropin releasing hormone (GnRH) analogues appears to protect women from POF. We present our experience in SLE patients treated with triptorelin.Methods: Observational study of 15 women diagnosed of SLE who have received concomitant treatment with Cyc and GnRH analogues (tri...

Introduction: Characteristically the discordant thyroid function test has been attributed to TSH-producing hypophyseal adenoma, familial dysalbuminemic hyperthyroxinemia and thyroid hormone resistance syndrome. We presented 2 cases with raised peripheral thyroid hormones with detectable TSH due to the presence of auto-antibodies against the peripheral thyroid hormones (PTAAb). <thead valign="...

Background: Pregnancy may adversely affect the progression of diabetic retinopathy and can have serious implications for the pregnant women.Aim: To asses the impact of pregnancy on the progression of diabetic retinopathy in women with type 1 and type 2 diabetes mellitus and to identify risk factors for the progression of retinopathy during pregnancy.Methods: 306 diabetic women, 229 (75.4%) with type 1 and 77 (23.9%) with type 2 di...

Introduction: Genes involved in common complex disorders such as obesity, type 2 diabetes mellitus (T2DM), dyslipidemia or hypertension are not disease specific, since clinically related disorders also share genetic components. These diseases cluster together in the Metabolic Syndrome, a generalized pathology with increased cardiovascular risk in which insulin resistance is considered a key feature. Cysteine protease Calpain-10 (CAPN10) has been associated with T2DM, polycysti...

Introduction: Papillary Thyroid cancer (PTC) accounts for 80% or more of all thyroid malignancies and genetic alterations associated with the development and progresion of this type of carcinoma remains largely unknown. Chromosomal band 11q13 seems to be one of the most frequently amplified regions in human cancer. Allelic imbalance involving EMSY, CAPN5 and PAK1 loci in thyroid cancer, have never been investigated. The aim of our study was to investigate the existence of alle...

Introduction: Silent corticotroph tumours (SCT) are a pituitary tumours (PT) subtype of corticotroph lineage that do not clinically express Cushing disease. Inmunohistochemical (IHC) studies reveal no differences between SCT and functioning corticotroph tumours with Cushing Syndrome (FCT). However, the silencing mechanisms of this type of tumours are not fully understood.Aim: In an important series of SCT, to sequence the POMC gene and quantify ...

We aimed to assess the effect of sleeve gastrectomy (SG) on the metabolic and gut microbiota profiles in non-diabetic obese patients with different grade of insulin resistance (IR).Methods: Prospective study of 22 morbid non-diabetic obese patients (77.2% women, age 47.13±9.51 years, basal BMI 45.59±4.99 kg/m2, 11 IR and 11 non-IR) undergoing SG. A fasting blood sample was collected at baseline and at 6 months post-SG for the determi...

Introduction: The last World Health Organization (WHO) 2016 classification of Pituitary Tumours recommends the determination of transcription factors. During the last few years, silent variants of the main pituitary tumours (PTs) have been described. The mechanisms of silencing of these tumors are still unknown. POU1F1 (Pit1) encodes a member of the POU family of transcription factors that has a relevant role in the differentiation, proliferation and survival of three...

Hemoglobin A1c (HbA1c) is used for the long-term management of patients with diabetes mellitus (DM). Hemoglobin variants other than HbA1c and e-N-lysine-glycated HbA0 may cause analytical interference in determinations of HbA1c. Hemoglobin J is an abnormal hemoglobin, an alpha globin gene variant and present in various geographic locations. Hemoglobin J (depending on its type) has different characteristics and functions. For example hemoglobin J Capetown (α2 92Gln β2...

Background: The complex involvement of multiple metabolic defects in the pathogenesis of type 2 diabetes mellitus (T2DM) makes difficult the treatment in monotherapy, therefore, the use of different antidiabetic drugs with different and complementary mechanisms of action could result in better glycemic control with favorable metabolic changes.Objective: To determine the effectiveness and safety of the addition of a sodium-glucose co-transporter type 2 in...
