HbA1C stability – is posting samples reliable?

Davey Nicola , Wright Katherine , Natarajan Anuja ,

For the safe delivery of Paediatric Diabetes services at DBTH during the COVID pandemic a postal HbA1c service with patients collecting capillary blood samples to send to the laboratory for analysis was proposed. The aim of this pilot study was to assess stability of HbA1c at ambient temperature in capillary whole blood samples collected into Sarstedt Microvette EDTA tubes. Samples were analysed on the day of collection on the TOSOH G11 analyser and then re-assayed daily for u...

Effect of Specimen Repeated Freeze-Thaw Cycles on Urinary Gonadotropin Determined by Immunochemiluminometric Assays

Ma Yaping , Xu Zhuangjian , Hu Yu , Zhu Wenying , Wang Qing

Background: It remains unclear whether specimen repeated freeze-thaw cycles can influence urinary lutenising hormone (LH) and follicular stimulating hormone (FSH) assayed by immunochemiluminometric assays (ICMA).Objective and hypotheses: To investigate the effect of specimen repeated freeze-thaw cycles on urinary LH and FSH determined by ICMA.Method: The first morning-voided urine was collected and divided two parts. One part was s...

High Mobility Group Box 1 (HMGB1) is Increased in Adolescents with Polycystic Ovarian Syndrome (PCOS) and Decreases after Treatment with Myo-Inositol in Combination with α-Lipoic Acid (MYO+ALA)

PCOS treatment in adolescence should aim at improving ovarian function, based on the pathophysiology of this condition. We previously described in cystic fibrosis and then in the PCOS an increase in HMGB1, secondary to reduced cystic fibrosis transmembrane conductance regulator (CFTR) expression in the ovary, associated with insulin resistance and inflammation that both characterize PCOS. Inositols and ALA derivatives are considered a good therapeutic option for their possible...

A common polymorphism in the human P450 reductase gene (POR) causes defective steroid and drug metabolism due to protein instability

Rojas Velazquez Maria Natalia , Noebauer Mathias , Pandey Amit V

Cytochrome P450 oxidoreductase (POR) is the obligatory redox partner of steroid and drug-metabolizing cytochrome P450s located in the endoplasmic reticulum. Mutations in POR cause a broad range of disorders like congenital adrenal hyperplasia that may resemble bone malformations resembling Antley-Bixler syndrome. Genome sequencing studies have revealed the existence of a POR missense variant P228. We aimed to determine the detailed functional impact of POR variant P228L for it...

Background and Aims: A pre-clinical stage of type 1 diabetes (T1D) often precedes by many years the overt clinical symptoms. Diagnosis during this period is often difficult and is based on the presence of specific islet autoantibodies in the subject's blood. First-degree relatives of patients with T1D were tested using the 3 Screen ICA TM ELISA (RSR Ltd) for combined testing for autoantibodies to GAD65 (glutamic acid decarboxylase, 65kDa isoform), ZnT8 (z...

Background: Congenital diarrheal disorders (CDDs) are a large group of life-threatening genetic disorders that are frequently difficult to diagnose. We report four siblings from consanguineous kindred with persistent generalized malabsorptive diarrhea hypothyroidism, GH deficiency, intermittent diabetes insipidus, and monogenic obesity.Objective and hypotheses: To find the genetic etiology for the CDD in four cases from consanguineous family using homozy...

Paternally Inherited IGF2 Mutation Results in Intrauterine and Postnatal Growth Retardation

Begemann Matthias , Zirn Birgit , Santen Gijs , Wirthgen Elisa , Soellner Lukas , Buttel Hans-Martin , Schweizer Roland , van Workum Wilbert , Eggermann Thomas , Binder Gerhard

Background: IGF1 and IGF2 are major regulators of somatic growth acting mainly through the IGF1R. Variants in IGF1 and in IGF1R were identified to cause intrauterine and postnatal growth retardation but variants in IGF2 have not yet been reported.Method: In a multigenerational family four affected members (two siblings, one first degree cousin and the daughter of one sibling) exhibited severe growth retardation with heights between −4.2 and −...
