  • Challenging the status quo: A comparison of ion exchange chromatography
           with liquid chromatography–mass spectrometry and liquid
           chromatography–tandem mass spectrometry methods for the measurement of
           amino acids in human plasma

      Abstract: Annals of Clinical Biochemistry, Volume 57, Issue 4, Page 277-290, July 2020.
      BackgroundPlasma amino acid analysis is key to the diagnosis and monitoring of inherited disorders of amino acid synthesis, catabolism and transport. Ion exchange chromatography (IEC) is widely accepted as the gold standard method of analysis, but with the introduction of liquid chromatography tandem mass spectrometry (LC-MS/MS) and liquid chromatography mass spectrometry (LC-MS) methods, this should now be questioned.MethodsThe analytical performance of three commercially available reagent kits, Waters AccQ Tag™ ULTRA LC-MS, SpOtOn Amino Acids LC-MS/MS and Chromsystems MassChrom® Amino Acid Analysis LC-MS/MS, were evaluated and compared with Biochrom Physiological Amino Acids ion exchange chromatography. Correlation with IEC was assessed by Passing-Bablok regression, concordance correlation coefficients (CCC) and Bland-Altman analysis for 21 common amino acids. Calculation of the total error from imprecision and bias was also used to benchmark performance.ResultsThe MassChrom® and SpOtOn kits demonstrated acceptable inter-batch imprecision (CV

  • Functional vitamin B12 deficiency in phenylketonuria patients and healthy
           controls: An evaluation with combined indicator of vitamin B12 status as a
           biochemical index
    • Authors: Merve Akış, Melis Kant, İshak Işık, Pelin Teke Kısa, Engin Köse, Nur Arslan, Hüray İşlekel
      Pages: 291 - 299
      Abstract: Annals of Clinical Biochemistry, Volume 57, Issue 4, Page 291-299, July 2020.
      BackgroundVitamin B12 deficiency frequently appears in phenylketonuria patients having a diet poor in natural protein. The aims of this study were to evaluate vitamin B12 status in phenylketonuria patients by using combined indicator of vitamin B12 status (cB12) as well as methylmalonic acid and homocysteine, more specific and sensitive markers, in comparison with healthy controls.MethodsFifty-three children and adolescents with phenylketonuria under dietary treatment and 30 healthy controls were assessed cross-sectionally. Serum vitamin B12 and folate concentrations were analysed by chemiluminescence immunoassay. Plasma methylmalonic acid and total homocysteine concentrations were measured by liquid chromatography-tandem mass spectrometry and liquid chromatography, respectively. cB12 was calculated by using a formula involving blood parameters.ResultsMethylmalonic acid and folate concentrations in phenylketonuria group were higher compared with controls. Methylmalonic acid concentrations were high in 56.5% of the patients and 26.7% of the controls with normal vitamin B12 concentrations. Based on cB12, a significant difference within the normal values was detected between the groups. However, although 24.5% of phenylketonuria patients and 13.3% of controls had decreased vitamin B12 status according to cB12, there was no significant difference.ConclusionChildren and adolescents with phenylketonuria having a strict diet can be at risk of functional vitamin B12 deficiency. This deficiency can be accurately determined by measuring methylmalonic acid concentrations. Calculation of cB12 as a biochemical index did not provide additional information compared with the measurement of methylmalonic acid alone, but may be helpful for classification of some patients with increased methylmalonic acid as having adequate vitamin B12 status.

  • Measurement of faecal haemoglobin with a faecal immunochemical test can
           assist in defining which patients attending primary care with rectal
           bleeding require urgent referral

      Pages: 325 - 327
      Abstract: Annals of Clinical Biochemistry, Volume 57, Issue 4, Page 325-327, July 2020.
      BackgroundCurrent guidelines document persistent rectal bleeding as an alarm symptom in patients presenting to primary care. We studied whether a faecal immunochemical test could assist in their assessment.MethodsFrom December 2015, faecal immunochemical tests were routinely available to primary care when assessing patients with new-onset bowel symptoms: general practitioners were encouraged to include faecal haemoglobin concentration (f-Hb) within any referral to secondary care. Results with f-Hb ≥10 μg Hb/g faeces were defined as positive. The incidence of significant bowel disease (SBD: colorectal cancer [CRC], higher-risk adenoma [HRA: any ≥1 cm, or three or more] and inflammatory bowel disease [IBD]) at subsequent colonoscopy, referred symptoms and f-Hb were recorded.ResultsOf 1447 patients with a faecal immunochemical test result and colonoscopy outcome, SBD was diagnosed in 296 patients (20.5%; 95 with CRC, 133 with HRA, and 68 with IBD). Four hundred and sixty-two patients (31.9%) reported rectal bleeding: 294 had f-Hb ≥10 μg Hb/g faeces. At colonoscopy, 105/294 had SBD versus 14/168 with rectal bleeding and f-Hb

      BackgroundHarmonization of reference intervals for analytes that have a sound calibration and metrological traceability is a widely recommended practice. The UK Pathology Harmony has recently harmonized reference intervals for calcium and albumin. In this study, we have determined the reference intervals for calcium and albumin on the UK’s most commonly used analytical platforms.MethodA prospective reference population of healthy individuals was recruited according to the IFCC CRIDL criteria. A second indirect population was collected from 14 primary care setting and measured in laboratories using various analytical platforms and methods (Roche, Abbott, Beckman and Siemens analytical platforms).ResultsIn total, 299 subjects were recruited; the central 95th centile values for calcium for three out of four analytical platforms were in a close agreement with UK Pathology Harmony reference intervals of 2.2–2.6 mmol/L. Reference intervals of BCG methods from both cohorts and irrespective of analytical platforms were higher for both lower and upper reference limits than those for BCP. In comparison, the indirect study showed an age-related variation. The younger population reference intervals varied by up to 5.7% at the lower reference limit and up to 12% at the upper reference limit compared with Pathology Harmony reference intervals, and the older population showed a variation of up to 14% at both limits.ConclusionWhile calcium reference intervals can be a subject for harmonization, albumin reference intervals studied showed large variation which is unsupportive of embracing a common reference interval for albumin.

  • The impact of the analytical performance specifications of calcium and
           albumin on adjusted calcium
    • Authors: N Jassam, A Thomas, K Hayden, R Dearman, JH Barth
      Abstract: Annals of Clinical Biochemistry, Ahead of Print.
      AimThe generation of accurate, comparable results from traceable measurement procedures is a primary goal in harmonization efforts. In this study, the analytical performance of routine methods for calcium and albumin measurement is assessed to define the impact of the analytical bias of calcium and albumin on adjusted calcium equation performance and on reference intervals.MethodIn collaboration with the Wales External Quality Assurance Scheme, six months’ worth of anonymized data that cover a concentration range of clinical interest were collected. The data were grouped by analytical platforms/methods.ResultsAlbumin BCG methods are positively biased (8%) to BCP methods. The overall bias for BCP methods ranges from 5.1 to –4.3% and the overall bias for BCG methods is from 2 to –6.7%. Bias for both methods is higher than the allowable minimal bias for albumin. Calcium concentrations for Roche Cobas CPC and NM-BAPTA, Beckman Arsenazo III, Abbott Architect Arsenazo III were within bias of 1.5 to –1%. However, Siemens calcium methods CPC and Arsenazo III appear to suffer from concentration-dependent bias ranging from +3 to –6%, which exceeds even the minimal allowable limits for calcium (1.3%). Adjusted calcium shows significant bias of 11%. Even with the exclusion of Siemens Advia, the scatter of adjusted calcium results exceeds that for total calcium.ConclusionThis study shows wider than acceptable analytical variation for albumin and calcium. This variation may contribute to overall adjusted calcium equations variation and invalidate the application of a harmonized reference interval for calcium and albumin.

  • Serum myonectin is increased after laparoscopic sleeve gastrectomy
    • Authors: Lei Li, Qianqian Wang, Chengkun Qin
      Abstract: Annals of Clinical Biochemistry, Ahead of Print.
      ObjectiveMyonectin, a newly discovered myokine, enhances fatty acid uptake in cultured adipocytes and hepatocytes and suppresses circulating levels of free fatty acids in mice. Recent studies showed that serum myonectin concentration is negatively correlated with obesity. This study was undertaken to evaluate the change of serum myonectin in obese patients after laparoscopic sleeve gastrectomy.MethodsThis study was performed in a population of 42 obese and 58 control subjects from April of 2018 to December of 2019. All obese subjects underwent laparoscopic sleeve gastrectomy. Anthropometric measurements, lipid profiles, HbA1c and serum myonectin were assessed at baseline and six months after laparoscopic sleeve gastrectomy.ResultsSerum myonectin concentrations were significantly lower in the obese patients than in the controls. Serum myonectin concentrations were increased at six months after laparoscopic sleeve gastrectomy. Simple linear regression analysis indicated that serum myonectin was negatively correlated with weight, waist circumference, hip circumference, body mass index, fasting plasma glucose, homeostasis model assessment of insulin resistance and HbA1c. Only body mass index was still inversely correlated with serum myonectin after multiple linear regression analysis.ConclusionSerum myonectin is correlated with obesity and increased after laparoscopic sleeve gastrectomy.

  • Don’t seek, don’t find: The diagnostic challenge of
           Wernicke’s encephalopathy
    • Authors: Sara Kohnke, Claire L Meek
      Abstract: Annals of Clinical Biochemistry, Ahead of Print.
      Wernicke’s encephalopathy is caused by thiamine deficiency and has a range of presenting features, including gait disturbance, altered cognitive state, nystagmus and other eye movement disorders. In the past, Wernicke’s encephalopathy was described almost exclusively in the alcohol-dependent population. However, in current times, Wernicke’s encephalopathy is also well recognized in many other patient groups, including patients following bariatric surgery, gastrointestinal surgery, cancer and pancreatitis. Early recognition of Wernicke’s encephalopathy is vital, as prompt treatment can restore cognitive or ocular function and can prevent permanent disability. Unfortunately, Wernicke’s encephalopathy is often undiagnosed – presumably because it is relatively uncommon and has a variable clinical presentation. Clinical biochemists have a unique role in advising clinicians about potential nutritional or metabolic causes of unexplained neurological symptoms and to prompt consideration of thiamine deficiency as a potential cause in high-risk patient groups. The aim of this review is to summarize the clinical features, diagnosis and treatment of Wernicke’s encephalopathy and to highlight some non-traditional causes, such as after bariatric surgery.

      Abstract: Annals of Clinical Biochemistry, Ahead of Print.
      BackgroundMeasurement of testosterone (T), androstenedione (A4) and 17-hydroxyprogesterone (17OHP) usually requires a venous serum sample which may have implications for sample stability or collection.ObjectiveA liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay was developed for samples collected using Mitra devices. Analytical validation was completed, and sample comparisons were undertaken to assess Mitra versus venous samples.MethodSample was combined with deionized water and internal standard. After mixing, MTBE was added for extraction. The supernatant was transferred to a deep-well plate and dried prior to re-constitution. A HSS T3 column and Waters TQS Micro was used, the detected quantifier transitions were T m/z 289.2 > 96.95, A4 287.2 > 96.95 and 17OHP 331.25 > 96.95.ResultsMean recovery was 102% for T, 98% for A4 and 97% for 17OHP. Lower limit of quantification was 1 nmol/L for T/A4 and 4 nmol/L for 17OHP. T was linear up to 41.6 nmol/L, A4 41.9 nmol/L and 17OHP 72.6 nmol/L. Ion suppression was

  • Prealbumin: The clinical utility and analytical methodologies
    • Authors: Ruvini NK Ranasinghe, Milly Biswas, Royce P Vincent
      Abstract: Annals of Clinical Biochemistry, Ahead of Print.
      Prealbumin is a small protein which has been widely evaluated as a nutritional and a prognostic marker. The small size and concentration of prealbumin in blood proposes challenges on measuring it with high sensitivity and specificity. Over the years, a number of analytical methodologies have been developed, which may help establish prealbumin as a useful biomarker in routine clinical practice. The aim of the short review was to explore the current literature on the clinical utility of prealbumin and the advances made in the analytical methodologies of prealbumin. We searched MEDLINE, EMBASE and the Cochrane Library for articles published between January 1980 and July 2019, with the general search terms of ‘prealbumin’, ‘prognostic marker’, ‘nutritional marker’, ‘analytical methodologies’ and ‘malnutrition’. Additionally, we selected relevant articles and comprehensive overviews from reference lists of identified studies. The routine use of prealbumin in clinical practice remains debatable; however; it can complement clinical history, anthropometric assessment and physical examination to assess malnutrition with more certainty. Consensus on the clinical applications of prealbumin in the management of malnutrition is warranted.

  • Coronavirus disease 2019 (COVID-19) and the renin-angiotensin system: A
           closer look at angiotensin-converting enzyme 2 (ACE2)
    • Authors: Annalise E Zemlin, Owen J Wiese
      Abstract: Annals of Clinical Biochemistry, Ahead of Print.
      Since the first cases of atypical pneumonia linked to the Huanan Seafood Wholesale Market in Wuhan, China, were described in late December 2019, the global landscape has changed radically. In March 2020, the World Health Organization declared COVID-19 a global pandemic, and at the time of writing this review, just over three million individuals have been infected with more than 200,000 deaths globally. Numerous countries are in ‘lockdown’, social distancing is the new norm, even the most advanced healthcare systems are under pressure, and a global economic recession seems inevitable. A novel coronavirus (SARS-CoV-2) was identified as the aetiological agent. From experience with previous coronavirus epidemics, namely the severe acute respiratory syndrome (SARS) and Middle East Respiratory Syndrome (MERS) in 2004 and 2012 respectively, it was postulated that the angiotensin-converting enzyme-2 (ACE2) receptor is a possible port of cell entry. ACE2 is part of the renin-angiotensin system and is also associated with lung and cardiovascular disorders and inflammation. Recent studies have confirmed that ACE2 is the port of entry for SARS-CoV-2. Male sex, advanced age and a number of associated comorbidities have been identified as risk factors for infection with COVID-19. Many high-risk COVID-19 patients with comorbidities are on ACE inhibitors and angiotensin receptor blockers, and this has sparked debate about whether to continue these treatment regimes. Attention has also shifted to ACE2 being a target for future therapies or vaccines against COVID-19. In this review, we discuss COVID-19 and its complex relationship with ACE2.

      First page: 312
      Abstract: Annals of Clinical Biochemistry, Ahead of Print.
      IntroductionLaboratory comments appended on clinical biochemistry reports are common in the UK. Although popular with clinicians and the public, there is little evidence that these comments influence the clinical management of patients.MethodsWe provided reflex automated laboratory comments on all primary care lipid results including, if appropriate, recommendation of direct referral to the West Midlands Familial Hypercholesterolaemia service (WMFHS). Over a two-year period, the number GP referrals from the Wolverhampton City Clinical Commissioning Group (CCG) to the WMFHS were compared with four comparator CCGs of similar population size, who were not provided with reflex laboratory comments.ResultsOver the study period, the WMFHS received more referrals from Wolverhampton GPs (241) than any other comparator CCG (range 8–65) and greater than the combined referrals (172) from all four comparator CCGs.ConclusionTargeted reflex laboratory comments may influence the clinical management of patients and may have a role in the identification of individuals with familial hypercholesterolaemia.

  • Prospective study comparing the outcome of a population-specific adjusted

    • Authors: N Jassam, K Hayden, R Dearman, V Allgar, JH Barth
      First page: 316
      Abstract: Annals of Clinical Biochemistry, Ahead of Print.
      BackgroundCalcium circulates bound to albumin and changes in albumin concentration will therefore affect total calcium measurements. In order to mitigate this, correction factors are frequently used. The most widely used correction equation was described by Payne and colleagues in 1973. This equation was derived from well-defined hospitalized patients’ data. Current clinical practice is consistent with the general application of the adjusted calcium equation irrespective of clinical setting. This study aims to assess the validity of this approach by the derivation of a community care-specific adjusted calcium equation (‘community equation’) and the comparison of its performance to a hospitalized patient equation and ionized calcium.MethodRetrospective data were collected according to Payne’s criteria from an inpatient and community care setting. Data were used to derive the two equations: the in-patient equation and community equation. The outcome of these equations was compared with ionized calcium obtained from 123 healthy participants.ResultsThe community equation correctly identified the calcium status of 92% of the 123 healthy participants, while the inpatient equation identified 46% only. Regression analysis against ionized calcium showed a higher R2 for the community equation than for the inpatient equation. Furthermore, we have shown that mean albumin and calcium concentrations are significantly different between these two populations.ConclusionIn this study, we found that the diagnostic accuracy of the adjusted calcium equation in ambulant patients was improved by the derivation of a population-specific equation for the community care setting.
