Predictive value of HbA1c and glucose fluctuations in hypoglycemia risk in patients with type 1 diabetes

Guelho Daniela , Barros Luisa , Baptista Carla , Paiva Isabel , Gouveis Sofia , Saraiva Joana , Moreno Carolina , Carrilho Francisco

Introduction: Many patients with diabetes experience high variability in glucose concentrations which is associated with a risk of hypoglycemia. The aim of this was to compare the predictive value of HbA1C, mean interstitial glucose (MIG), and glucose variability (GV) in the risk of hypoglycemia in patients with type 1 diabetes (T1D).Methods: Continuous glucose monitoring, using CGMS system, was performed in 130 T1D patients with diabetes duration of 17....

Relationship between metformin treatment and hyperlactacidemia diagnosed at the emergency room

Guelho Daniela , Paiva Isabel , Fonseca Isabel , Gouveia Sofia , Saraiva Joana , Moreno Carolina , Carvalheiro Manuela , Carrilho Francisco

Introduction: Renal function and glucose lowering therapy, particularly metformin, influence serum lactate concentration in patients with type 2 diabetes (T2D). However, seems to be an acute precipitating event that triggers hyperlactacidemia and metabolic acidosis. This study aims to assess prevalence of hyperlactacidemia in T2D patients who presented at emergency room (ER), calculate relative risk of hyperlactacidemia in diabetics under metformin, identify predictive factors...

The effect of anorexia nervosa on bone

Vicente Nuno , Rodrigues Dircea , Barros Luisa , Guelho Daniela , Cardoso Luis , Oliveira Diana , Martins Diana , Ventura Mara , Lages Adriana , Carrilho Francisco

Introduction: One of the most common endocrine complications of anorexia nervosa (AN) is the decrease in bone mineral density. The authors evaluated the predictive factors of osteopenia and osteoporosis in AN patients admitted with low weight.Patients and methods: Retrospective analysis of 45 patients admitted with AN between 2001 and 2015 in the Endocrinology department, corresponding to 63 admissions. Bone mineral density was classified according to WH...

Addison disease in antiphospholipid syndrome – case report

Oliveira Diana , Paiva Sandra , Rodrigues Marcia , Guelho Daniela , Cardoso Luis , Vicente Nuno , Martins Diana , Lages Adriana , Ventura Mara , Carrilho Francisco

Introduction: Primary adrenal insufficiency or Addison disease (AD) is a potentially fatal condition if not diagnosed in time. Rarely, it can arise as a manifestation of antiphospholipid syndrome (APS), caused by adrenal venous thrombosis and consequent hemorrhagic infarction.Case report: We present the case of a 36-year-old caucasian woman with APS diagnosis since she was 24, with history of arterial hypertension and multiple thrombotic events (deep vei...

Craniopharyngiomas–35 years of experience in a central hospital’s Endocrinology Department

Oliveira Diana , Paiva Isabel , Guelho Daniela , Cardoso Luis , Vicente Nuno , Martins Diana , Lages Adriana , Ventura Mara , Paiva Sandra , Carrilho Francisco

Introduction: Craniopharyngiomas are rare epithelial tumors of the sellar and parasellar region, with high survival rates but with frequent tumor recurrence or persistence.Methods: Information collection from clinical records and review of the epidemiology, diagnosis, treatment and follow-up of patients with diagnosis of craniopharyngioma followed in an Endocrinology Department between 1980 and 2015. Statistical analysis using SPSS v. 22.0.<p class="...

Contribution of glucose variability to HbA1c levels in patients with type 1 diabetes

Cardoso Luis , Batista Carla , Rodrigues Dircea , Moreno Carolina , Guelho Daniela , Vicente Nuno , Balsa Margarida , Martins Diana , Oliveira Diana , Carrilho Francisco

Background: Optimal management of type 1 diabetes requires full understanding of the relationships between the triad: HbA1c, fasting plasma glucose, and glucose variability (GV). As GV may contribute to HbA1c we assessed the influence of GV in HbA1c levels.Research design and methods: We retrospectively analysed 9393 h of continuous glucose monitorings (CGMs) from 61 patients with type 1 diabetes. Periods of 24 h with missing values were excluded. We cal...

Post-operative serum cortisol levels as predictors of recurrence in Cushing's disease

Martins Diana , Guelho Daniela , Paiva Isabel , Baptista Carla , Vicente Nuno , Cardoso Luis , Oliveira Diana , Balsa Margarida , Carrilho Francisco

Introduction: Cushing’s disease (CD) is characterized by increased secretion of ACTH often as a result of a pituitary adenoma. The surgical success rates after transsphenoidal pituitary surgery (TSS) range from 53 to 96% in different centres. Postoperative cortisol levels have been proposed as the standard criteria for prediction of surgical remission however, this variable is subject of a variety of interferences.Objectives: Evaluate the potential ...

Endocrine manifestations of Langerhans cell histiocytosis

Cardoso Luis , Gomes Leonor , Rodrigues Dircea , Moreno Carolina , Guelho Daniela , Vicente Nuno , Balsa Margarida , Martins Diana , Oliveira Diana , Carrilho Francisco

Introduction: Langerhans cell histiocytosis (LCH) is a rare disorder characterized by proliferation/accumulation of cells phenotypically similar to skin Langerhans cells. Clinical presentation and aggressiveness are very heterogeneous, from benign to disseminated forms that cause significant morbi-mortality, particularly endocrine failures.Case 1: A 15-year-old Caucasian woman presented with a 14-month history of headaches, secondary amenorrhea. She repo...

Medullary thyroid carcinoma in multiple endocrine neoplasia 2A: a therapeutic challenge

Cardoso Luis , Rodrigues Dircea , Costa Gracinda , Moreno Carolina , Guelho Daniela , Vicente Nuno , Balsa Margarida , Martins Diana , Oliveira Diana , Carrilho Francisco

Introduction: Medullary thyroid carcinoma (MTC) occurs in a hereditary pattern in 25% of cases. Virtually all patients with multiple endocrine neoplasia 2A (MEN2A) develop MTC. MTC aggressiveness and natural history varies according to the RET mutation. Prophylactic thyroidectomy may cure and/or prevent metastatic disease in most cases.Case report: A 27-year-old man with past history of colostomy at 5 months of age for Hirschsprung disease and t...

Type 2 polyglandular autoimmune syndrome and Turner syndrome

Moreno Carolina , Rodrigues Dircea , Vieira Alexandra , Ruas Luisa , Saraiva Joana , Guelho Daniela , Cardoso Luis , Vicente Nuno , Carrilho Francisco

Introduction: Individuals with Turner syndrome (TS) are prone to develop autoimmune conditions. The most frequently found are Hashimoto’s thyroiditis, type 1 diabetes, coeliac disease, and inflammatory bowel disease. In patients with TS, Addison’s disease isolated or combined with other autoimmune disease as type 2 polyglandular autoimmune syndrome, is a rare finding.Case report: We report a case of a 41-year-old female patient, with severe ast...
