A rare cause of artifactual hypoglycemia

Mertens Jonathan , Haddad Maryam

Background: Glycemia point-of-care testing (POCT) is performed with fingerstick capillary whole-blood glucose measurement. These values correlate well with plasma glucose values. Hypoglycemia can be observed with POCT but should always be confirmed on plasma. True hypoglycemia must meet Whipple’s triad: signs/symptoms of hypoglycemia; low plasma glucose; improvement after glucose administration. Artifactual hypoglycemia is a discrepancy between POCT and plasma glucose and...

The importance of post-resection histologic confirmation in the diagnosis and differentiation of neuro-endocrine tumors of the lung

Jonathan Mertens , Pascale Abrams

Introduction: First assessment of lung tumors is often performed by imaging combined with biopsy. This is necessary for immunohistochemical tumor typing, evaluation of treatment options and prognosis. It has been shown in literature reviews that Endobronchial ultrasound (EBUS) with fine needle aspiration cytology (FNAC) is not inferior in diagnostic quality, but much less invasive than mediastinoscopy of chest laparotomy (1–3). In this case report we will describe the cut...

CREST syndrome diagnosed because of faulty point-of-care glycaemia: a case report

Jonathan Mertens , Maryam Haddad , Christophe de Block

Background: Glycaemia point-of-care testing (POCT) is performed with fingerstick capillary whole-blood glucose measurement. These values normally correlate well with plasma glucose values. Hypoglycemia can be observed with POCT but should always be confirmed on plasma. True hypoglycemia must meet Whipple’s triad: signs/symptoms of hypoglycemia; low plasma glucose; improvement after glucose administration. Artifactual hypoglycemia is defined as a discrepancy between POCT a...

A hyperglycemic crisis as a first appearance of newly onset diabetes mellitus in a patient using dexamethasone: Blame the usual suspect or accuse a new one?

Mertens Jonathan , Martens Caroline , Vermeulen Griet

We describe the case of a 60-year old woman admitted to the intensive care unit (ICU) for progressively diminishing consciousness and severe lethargy. The patient was recently diagnosed with small cell lung carcinoma with solitary cerebral metastasis. In order to shrink the metastasis-induced cerebral edema she was treated with dexamethasone. She was hospitalized four days before admission to the ICU to start carboplatin-etoposide based chemotherapy. The day of admission she h...

The role of estimated glucose disposal rate as a predictor of insulin resistance, NAFLD and major adverse cardiovascular events in type 1 diabetes mellitus

Mertens Jonathan , Block Christophe De , Dirinck Eveline , Francque Sven

Background and AimsPeople with type 1 diabetes (T1D) have an increased risk of cardiovascular disease (CVD) despite insulin therapy to treat hyperglycaemia. Insulin resistance may be a contributing factor to CVD. Insulin resistance is strongly associated with NAFLD, which is increasingly linked to CVD. The estimated glucose disposal rate (eGDR) correlates well with the euglycemic clamp, which is the gold standard to assess insulin resistance in T1D, but ...

Estimated glucose disposal rate, non-alcoholic fatty liver disease and micro- and macrovascular complications in type 1 diabetes: Towards a new biomarker?

Jonathan Mertens , Jonas Weyler , Luisa Vonghia , Wilhelmus Kwanten , Eveline Dirinck , Sven Francque , Christophe De Block

Background and aims: Insulin resistance is increasingly prevalent in patients with type 1 diabetes (T1D). Insulin resistance is associated with both cardiovascular complications and non-alcoholic fatty liver disease (NAFLD), but its assessment is challenging in T1D due to the technical difficulties of the euglycaemic clamp technique. The estimated glucose disposal rate (eGDR) is a validated alternative to quantify insulin resistance in T1D, but its role in clinical practice is...

Insulin resistance as indexed by the estimated glucose disposal rate and liver fat content are correlated in type 1 diabetes

Mertens Jonathan , Spinhoven Maarten , Dirinck Eveline , Vonghia Luisa , Francque Sven , De Block Christophe

Introduction: The prevalence of metabolic syndrome is increasing in individuals with T1D, which could potentiate the development of NAFLD. The pathophysiology of NAFLD in T1D is still unclear, due to the co-existence of predisposing and protective factors. Insulin resistance (IR) is theorized as a key driver of NAFLD.Aim: We investigated the association between liver fat content (LFC), NAFLD, and IR in individuals with T1D. Subjects underwent magnetic re...

The insulin sensitivity index derived from euglycemic clamps is correlated to liver fat content determined by magnetic resonance spectroscopy in type 1 diabetes*

Jonathan Mertens , Rie Braspenning , Floris Vanhevel , Maarten Spinhoven , Sven Francque , Block Christophe De

Background: Insulin resistance is proposed as a causative factor of non-alcoholic fatty liver disease (NAFLD) in the general population. Reports on NAFLD in type 1 diabetes (T1D) are increasing , but whether insulin resistance is linked to NAFLD in this population needs elucidation. Furthermore, people with T1D are an excellent model to investigate insulin resistance in relation to NAFLD without confounding by autologous insulin production.Aims and Metho...

Diagnostic accuracy of fatty liver index in type 1 diabetes mellitus patients

Mertens Jonathan , Eveline Dirinck , Jonas Weyler , Luisa Vonghia , Sven Francque , Christophe De Block

Introduction: Nonalcoholic fatty liver disease (NAFLD) affects ±55% of subjects with type 2 diabetes and contributes to cardiovascular mortality. NAFLD data in type 1 diabetes (T1DM) are scarce. Biopsy is the diagnostic reference but is not suited for routine screening. Ultrasound (US) is validated to diagnose steatosis as first-line imaging but is restricted to trained operators. The Fatty Liver Index (FLI) is a score to predict fatty liver based on triglycerides, Body M...

Lipid accumulation product can accurately rule out, but not rule in non-alcoholic fatty liver disease in type 1 diabetes

Mertens Jonathan , Dirinck Eveline , Vonghia Luisa , Francque Sven , Block Christophe De

IntroductionLipid accumulation product (LAP), an index based on waist circumference (WC) and serum triglyceride levels, is associated with the presence and severity of non-alcoholic fatty liver disease (NAFLD). However, its potential as a risk marker of NAFLD in subjects with type 1 diabetes (T1D) has not been studied yet.AimsThis study evaluated the ability of LAP to estimate the presence of NAFLD in adults ...
