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....

Primary hyperparathyroidism: retrospective evaluation

Santos Jacinta , Paiva Isabel , Barros Luisa , Vieira Alexandra , Alves Marcia , Gouveia Sofia , Carvalheiro Manuela

Introduction: Primary hyperparathyroidism (PHP) results from an excessive secretion of parathyroid hormone (PTH), typically leading to hypercalcaemia. This disorder is more common than previously expected, since it is frequently diagnosed in asymptomatic patients.Objectives: To characterize a group of patients with PHP, in what concerns to: age, clinical presentation, biochemical and imaging evaluation, treatment and evolution.Pati...

Hematoma: unusual presentation of adrenal masses

Vieira Alexandra , Baptista Carla , Paiva Isabel , Barros Luisa , Santos Jacinta , Martinho Mariana , Carrilho Francisco , Carvalheiro Manuela

Introduction: Adrenal hematomas are very rare entities. They occur often associated with: trauma, anticoagulation, coagulopathy, septicemia, pregnancy complications or tumors. When none of these predisposing factors is present, diagnosis and treatment can become a real challenge.Case report: A 19-years-old woman presented with complaints of asteny, loss of appetite, loss of 10 kg in a month, and pain in right lumbar and abdominal regions. No other compla...

Characterization of a young population of type 1 diabetics

Vieira Alexandra , Fagulha Ana , Barros Luisa , Figueiredo Julia , Santos Jacinta , Martinho Mariana , Carrilho Francisco , Carvalheiro Manuela

Introduction: Type 1 diabetes is one the most common chronic diseases found in children and youngsters.Objectives: Characterization of a sample of young type 1 diabetic patients, treated with multiple daily injections of insulin.Patients and methods: Analysis of patients files with ages between 11 and 26 years observed on diabetology consultation during the first semester of 2008, with diagnosis of diabetes for at least 6 months. P...

Prevalence of cardiovascular risk polymorphisms and its association with microvascular complications in an adolescent type 1 diabetes population

Melo Miguel , Fagulha Ana , Barros Luisa , Santos Jacinta , Vieira Alexandra , Carvalheiro Manuela

Objectives: To determine the prevalence of several polymorphisms associated with increased cardiovascular risk in a group of adolescents with T1DM. To study the possible association of some polymorphisms with the occurrence of microvascular complications.Methods: Patients were randomly selected from our outpatient clinic. The following polymorphisms were studied:: ACE Ins/Del, Apo B R3500Q, Apo E2, 3, 4, MTHFR C677T and A1298C, PAI 4G/5G, ITGB3 PL(A1)/(A...

Insulin production by human spermatozoa in response to glucose stimuli

Carrageta David F. , Oliveira Pedro F. , Barros Alberto , Monteiro Mariana P. , Alves Marco G.

IntroductionMetabolic homeostasis in the testis is essential for a healthy spermatogenesis. Insulin is regarded as one of the most important intervenients in the metabolic regulation of spermatogenesis, where it acts directly on the differentiation of spermatogonia into primary spermatocytes or indirectly through the metabolic modulation of Sertoli cells. Additionally, insulin is hypothesized to play a major role on human spermatozoa capacitation, althou...

New variant of the casr gene (c.2459c > t) associated with primary hypoparathyrodism – a case report

Lavrador Mariana , Lages Adriana , Bárbara Araújo , Luísa Barros , Paiva Isabel

BackgroundAutosomal dominant hypocalcaemia, caused by either inherited or de novo mutations in calcium-sensing receptor gene (CASR), is biochemically characterized by the presence of hypocalcaemia, hypercalciuria and inappropriately low levels of PTH. Receptor-activating mutations induce an increase sensitivity to calcium by parathyroid and renal cells, leading to suppression of PTH synthesis and consequently hypocalcaemia. Clinical manifestations are va...

Clinical spectrum associated with variants in the ins gene in patients with suspected monogenic diabetes

Gomes Porras Mariana , Vallejo Mora Rosario , Soledad Ruiz De Adana Navas Maria , Campos Barros Angel

Background and aims: INSmutations can cause INS-MODy and have been described more frequently in cases of neonatal diabetes mellitus. The reported phenotypic expression of INS-MODy is quite variable.Objective: To clinically, biochemically and molecularly characterize INS-MODy patients in two Spanish tertiary level hospitals during the period 2009-2023.Methods: Cross-sectional study that included 121 pediatric patients with ...

Hypoglycemia and impared hypoglycemia awareness: frequency and relevance in type 1 diabetes under continuous subcutaneous insulin infusion

Mafalda , Carreira Ana , Vieira Ines , Barros Luisa , Melo Miguel , Rodrigues Dircea , Oliveira Patricia , Baptista Carla , Moreno Carolina , Paiva Isabel

Introduction: Continuous subcutaneous insulin infusion (CSII) therapy in type 1 diabetes (T1D) reduces the risk of hypoglycemia. Hypoglycemia remains a treatment-limiting factor. Impared hypoglycemia awareness (IHA) occurs in 25% of T1D cases and seems to be underestimated by continuous glucose monitoring (CGM). Glycemic variability (GV) is a increasingly valued parameter as a predictor of hypoglycemia and risk of chronic complications.Objective: Analysi...

Type 1 diabetes on continuous subcutaneous insulin infusion: impact of glycaemic control on quality of life

Carreira Ana , Ferreira Mafalda , Vieira Ines , Lavrador Mariana , Barros Luisa , Baptista Carla , Moreno Carolina , Melo Miguel , Paiva Isabel

Background: In type 1 diabetes (T1D), quality of life (QoL) and the effectiveness of treatment influence each other. QoL has been associated with glycaemic control assessed by HbA1c in T1D on continuous subcutaneous insulin infusion (CSII), but data on the relationship between Continuous Glucose Monitoring (CGM) metrics and QoL are scarce.Objectives: To assess QoL and the association between CGM metrics and QoL in T1D on CSII.Metho...
