Mutations in the ELANE gene, which encodes the neutrophil elastase (NE) protein in neutrophils, result in ELANE-related neutropenia. ELANE-related neutropenia encompasses both cyclic neutropenia (CN) and severe congenital neutropenia (SCN), with ELANE mutations seen in a majority of SCN and almost all of CN patients. Clinical history in affected individuals typically reveals recurrent episodes of fever, oral ulcerations and bacterial as well as fungal infections, correlating with periodic oscillations or chronically low levels in the absolute neutrophil count (ANC). ELANE-related neutropenia is characterised by severely low neutrophil counts where ANCs may drop as low as zero. A two-year-old child presented at our hospital with a longstanding history of recurrent bacterial infections and previous admissions at another centre during some of these infectious episodes. Her full blood count demonstrated a markedly low ANC, which was chronic on assessment of her previous results. Decreased granulopoiesis with maturation arrest was seen on her bone marrow and genetic testing for the ELANE gene demonstrated a pathogenic variant of the mutation. Treatment with granulocyte colony-stimulating factor (G-CSF) was initiated.

Accreditation is an official recognition that a facility or laboratory is competent to perform specific tasks and has a documented manual on a Quality Management System (QMS) in place. According to the Accreditation Act 19 of 2006, South African National Accreditation Systems (SANAS) is the only internationally recognised accreditation body in South Africa. The International Organization for Standardization (ISO) standard specifically for medical laboratory accreditation is ISO 15189:2012. This review is designed to bring awareness of accredited and unaccredited medical diagnostic laboratories in SA; to look at the number of accredited, unaccredited laboratories and the rate of accreditation growth; to examine the state of accreditation in South Africa with regard to how many are accredited, suspended or withdrawn; and to highlight the advantages of being an accredited laboratory. It also examines the nonconformances commonly raised during assessment and an overview of accreditation around the world. Upon accreditation, the laboratory is given the right to use the SANAS symbol on patient request forms or results as a confirmation of competency. This has motivated more and more laboratories to be accredited. Diagnostic laboratories contribute much toward the final decisions taken by clinicians to diagnose the patients or treatment; this may be from an accredited or non-accredited laboratory. Since patient care is inextricably linked to pathology testing, every laboratory should engage a premium QMS and be evaluated by an accreditation body to ensure that patients receive a trustworthy report. Accreditation is a voluntary process in South Africa but mandatory in some Western countries. Although some laboratories might lose accreditation along the way, the ratio compared to those accredited is still very small. The fact that a majority remain accredited is a good indication of a well-implemented QMS. The challenges faced by the medical technologist-owned laboratories remain, as they are still not accredited.

Background: Preoperative urea and electrolyte (U&E) panels are frequently requested for major surgery patients at risk for postoperative acute kidney injury (AKI). There is only one published study that has audited unnecessary preoperative U&E test panel utilisation in major surgery patients at a South African (SA) public sector hospital. This has significant implications for laboratory workloads, healthcare expenditure, and patient-friendly practice in the resource-limited SA public healthcare sector. Objective: To audit preoperative U&E panel requests in a sample of SA patients undergoing major orthopaedic surgery. Methods: We conducted a retrospective audit of adult primary hip arthroplasty patients who attended a quaternary SA hospital. Data on demographics, medical history, preoperative anaesthetic evaluations, operation details, and U&E panel requests were collected from each patient’s medical chart. The National Institute for Health and Care Excellence (NICE) guidelines, based on American Society of Anesthesiologists (ASA) grading and the presence of AKI risk factors, was used to distinguish between necessary and unnecessary preoperative U&E requests. We used descriptive statistics to analyse our study data. Results: Of the 175 patients comprising our study sample, 23 (13.1%) had preoperative U&E panels requested unnecessarily. All 23 patients were otherwise healthy and did not have any AKI risk factors. Conclusion: A small proportion of preoperative U&E test panels in our study sample of major orthopaedic surgery patients were deemed unnecessary. With that being said, there is still room for improvement in practices around preoperative U&E panel requests, which could be achieved through educational, computerised, and audit feedback interventions.

Objective: This study was conducted as a part of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) global study for establishing reference intervals (RIs) of common laboratory tests for the South African population considering gender, ethnicity, age and body mass index (BMI). Methods: The researchers recruited 1 143 apparently healthy volunteers aged 18–65: 551 African (Afr) and 592 non-African (NAfr) (comprising 383 Caucasian and 209 Mixed Ancestry). Serum samples were measured for 40 chemistry and immunochemistry analytes. The standard deviation ratio (SDR) guided the need for partitioning reference values according to gender, ethnicity and age using a threshold of ≥ 0.4. The latent abnormal values exclusion (LAVE) method was applied to reduce influences of latent diseases before deriving RIs using both parametric and non-parametric methods. Results: Based on SDRsex, males showed higher albumin, uric acid, creatinine, AST, CK and ferritin. Based on SDRRC, Afr compared to NAfr showed (i) higher total protein, amylase, CRP, immunoglobulin G and A and (ii) lower total bilirubin, total cholesterol, low-density lipoprotein cholesterol (LDL-C), ALT and cholinesterase. Both age-related changes in glucose and LDL-C, and BMI-related changes in ALT, ALP and LDH were more prominent in NAfr. RIs were determined according to gender, age and ethnicity. The LAVE method was effective in lowering the upper RI limits (UL) of nutritional markers such as γGT and CRP. Compared to the non-parametric method, the parametric method gave narrower confidence intervals of ULs for analytes with skewed distributions. Conclusion: Establishing RIs by considering ethnicity was essential in many analytes in South Africa. Age and BMI-related changes differed greatly between Afr and NAfr.

Background: The global emergence of antimicrobial resistance (AMR) in Neisseria gonorrhoeae to various antibiotics is a public health concern. To date, there have been no published South African studies that have compared the primary swab to the cultured isolates for the detection of N. gonorrhoeae AMR determinants. This study provides data on such a comparison. Methods: Paired endocervical swabs were collected from 307 pregnant women. The first swab was stored in an Amies charcoal transport media for culture assessment and the second swab was used for the molecular detection of resistant determinants. Specific targets (genes/plasmids/mutations) associated with resistance to penicillin, tetracycline, ciprofloxacin, spectinomycin, cefixime, azithromycin and ceftriaxone were detected from both the cultured isolates and the endocervical swabs. Results: Of the 307 samples tested in this study, only six samples tested positive for culture. A total of 24 samples tested positive for N. gonorrhoeae with the quantitative polymerase chain reaction (qPCR) assay. The six samples which tested positive for culture fell within the qPCR positives group. Since this study was designed to directly compare the culture swabs to the endocervical swabs for the detection of AMR determinants, the current analysis included only the six culture samples and six paired endocervical swab samples (n = 6). All six isolates were resistant to tetracycline and penicillin G while five of the six isolates were resistant to ciprofloxacin. All isolates were susceptible to the remaining antimicrobials. There was a 100% correlation between the cultured isolates and endocervical swabs for detecting the specific AMR determinants, conferring resistance to tetracycline, penicillin G and ciprofloxacin. Conclusion: Based on the findings of this study, tracking emerging patterns of resistance from the molecular level using only the endocervical swabs may serve as an attractive future research direction.

Introduction: Preoperative hypoalbuminaemia is a risk factor for surgical site infection (SSI) in the South African (SA) setting. However, the predictive accuracy of preoperative hypoalbuminaemia has not been tested against established SSI risk stratification models in our setting, which could have important implications for SSI prevention strategies. With reference to SSI in SA settings, the study objective was to compare the overall predictive accuracy of preoperative hypoalbuminaemia with that obtained for the SENIC/NNIS risk scores. Method: This was a sub-analysis of a pre-existing laparotomy patient registry (N = 439). Variables collected as part of the registry included preoperative serum albumin measurements and all parameters of the SENIC/NNIS risk scores. Preoperative hypoalbuminaemia was defined as preoperative serum albumin of < 30 g/L. The study outcome was SSI up to 30 days postoperatively. Overall predictive accuracy was determined through a receiver operator-characteristic (ROC) curve analysis, with results presented as C-statistics (95% confidence intervals [CI]). Results: The C-statistics obtained for preoperative hypoalbuminaemia, the SENIC risk score, and the NNIS risk score were 0.677 (CI: 0.609–0.746), 0.652 (CI: 0.582–0.721), and 0.634 (CI: 0.563–0.705). Conclusion: All three methods display similar predictive accuracy for SSI. However, preoperative hypoalbuminaemia has several practical advantages over the SENIC/NNIS scores which must be considered.
