Impact of COVID-19 on laboratory professionals-A descriptive cross sectional survey at a clinical chemistry laboratory in a developing country

Background: The lab professionals at one end are at increased risk of contracting the infection while on the other end have to deal with the various challenges during the Coronavirus Disease 2019 (COVID-19) outbreak. This survey was undertaken to analyze the lab professionals\u27 perspectives, in terms of the challenges, financial implications, fears, motivation and satisfaction from organizational processes and policies adopted, amid the COVID-19 crisis.Material & methods: The study utilized a cross-sectional survey design. The survey was administered online via the google docs survey tool from medical laboratory professionals (n = 64) serving at the section of Clinical Chemistry, department of Pathology and Laboratory Medicine, the Aga Khan University (AKU), Pakistan from June 4th to 14th 2020. A team consisting of three Clinical Chemistry consultants serving as faculty at the section, designed the survey questionnaire. The responses were recorded on a five-point Likert Scale (1 = strongly disagree, 2 = disagree, 3 = neutral, 4 = agree and 5 = strongly agree). The statistical analysis was performed using the Microsoft Excel 2013. Frequency and percentages were calculated for gender, experience and designation while descriptive results based on the responses were also recorded.Results: The response rate was 78% (n = 50). 60% responded that the current lifestyle adopted during the pandemic was not better than the traditional one. The fear of employment termination and financial challenges were being faced by 42% and 78% respondents respectively. The quality of family life was improved in 54% cases while 96% were of the view that their social activities at work have suffered. Whereas, 22% were not satisfied by the measures taking by the management during the outbreak.Conclusion: The findings of this survey provide laboratorians\u27 perspective, in times of such crisis and provides us certain lessons to prepare for such unpredicted situations in future

Evaluation of \u27CKD-EPI Pakistan\u27 equation for estimated glomerular filtration rate (eGFR): a comparison of eGFR prediction equations in Pakistani population

Objective: To evaluate the results of 24-hour urinary creatinine clearance (CrCl) with estimated glomerular filtration rate (eGFR) using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), CKD-EPI Pakistan (CKD-EPI Pak), Cockcroft Gault (CG) and 4-variable Modification of Diet in Renal Disease (MDRD) equations.Study Design: Descriptive, cross-sectional study.Place and Duration of Study: Section of Clinical Chemistry, Department of Pathology and Laboratory Medicine, The Aga Khan University, Karachi, from June to October 2013. Methodology: Laboratory data of subjects ≥18 years ordering 24-hour urinary CrCl from June to October 2013 was retrieved. Statistical comparison of eGFR using CKD-EPI, CKD-EPI Pak, CG and MDRD with the timed urine collection CrCl was done using regression analysis. Result: The mean age of the group (n=670) was 51.3 ±15.4 years with a median of 53 (IQR:22.3) years, 55.7% being males. Median BMI of males and females was 26.98 kg/m2(IQR: 7.09) and 26.16 kg/m2(IQR: 6.97), respectively. Mean GFR using 24-hour creatinine clearance was 57.1 ±35.9 ml/min/1.73m2 with a median of 51 ml/min/1.73m2. Urinary creatinine clearance showed strong correlation with CG, MDRD, CKD-EPI and CKD-EPI Pak, showing r=0.78, r=0.79, r=0.82, and r=0.82, respectively. Sensitivity was highest for the CKD-EPI Pakistan (84.7%). Similarly, CKD-EPI Pakistan equation showed the highest agreement (88.7%) with CrCl compared to the other formulae. Conclusion: The CKD-EPI Pak equation is more accurate and precise than the CG, CKD-EPI and MDRD in estimating GFR in Pakistani population

Illuminating the dark side-vitamin D status in different localities of Karachi

Abstract This study was conducted to determine the association between place of residence (grouped into neighbourhoods), and 25-hydroxy D (25[OH]D) levels of individuals of Karachi. Addresses of 4788 individuals tested for 25[OH]D at the clinical laboratory of the Aga Khan University (AKU), Karachi, from January 2007 to June 2008 were reviewed. The neighbourhoods were categorized into ten, based on locality attributes. A high overall prevalence (74%) of vitamin D deficiency (VDD) was observed. There was a significant difference (p-value \u3c 0.01) between mean log 25[OH]D levels amongst neighbourhoods grouped according to distinct housing structure attributes and localities. A high frequency of VDD in all the studied localities of an urban city warrant dietary vitamin D supplementation and food fortification

X-linked hypophosphatemic osteomalacia with PHEX mutation presenting late in Pakistan

Abstract.introduction.and.importance: Autosomal dominant hypophosphatemic rickets is the most common form of rare rickets, commonly manifests in children but sometimes the condition remains undiagnosed due to lack of knowledge &/or awareness of treating physicians or surgeons.Case presentation: We describe a case of 43 years old female with multiple fragility fractures since childhood, corrected surgically but never investigated. She had stunted growth, bowing deformities and loss of teeth.Clinical discussion: A detailed history and examination along with metabolic and genetic work up mounted the diagnosis of X linked hypophosphatemic osteomalacia. The pathophysiology involves the mutation or the loss of the phosphate regulating gene on PHEX, that causes reduced mineralization of bones and teeth.Conclusion: Diagnostic delay in this patient resulted in increased disabilities affecting her mobility and lif estyle

Osteoporosis and its perspective in Pakistan: A review of evidence and issues for addressing fragility fractures

Despite major advances in osteoporosis diagnosis and treatment, low rates of investigating and treating osteoporosis in patients with fragility fracture are reported in Pakistan. Cost of therapies, time and cost of resources for diagnosis, concerns about medications and lack of clarity regarding the onus of responsibility to undertake this care, are some of the barriers to osteoporosis identification and treatment. Data from our part of the world on osteoporosis as well as on fragility fractures is sparse. This review addresses the current screening and diagnostic strategies for osteoporosis and reviews the existing literature to highlight the issues prevalent in our society on this major public health problem

Fourier transform infrared spectroscopy for analysis of kidney stones

Purpose: To compare the results of a chemical method of kidney stone analysis with the results of Fourier transform infrared (FT-IR) spectroscopy. Materials and Methods: Kidney stones collected between June and October 2015 were simultaneously analyzed by chemical and FT-IR methods. Results: Kidney stones (n=449) were collected from patients from 1 to 81 years old. Most stones were from adults, with only 11.5% from children (aged 3-16 years) and 1.5% from children aged adults, the calcium oxalate stone type, calcium oxalate monohydrate (COM, n=224), was the most common crystal, followed by uric acid and calcium oxalate dihydrate (COD, n=83). In children, the most frequently occurring type was predominantly COD (n=21), followed by COM (n=11), ammonium urate (n=10), carbonate apatite (n=6), uric acid (n=4), and cystine (n=1). Core composition in 22 stones showed ammonium urate (n=2), COM (n=2), and carbonate apatite (n=1) in five stones, while uric acid crystals were detected (n=13) by FT-IR. While chemical analysis identified 3 stones as uric acid and the rest as calcium oxalate only. Agreement between the two methods was moderate, with a kappa statistic of 0.57 (95% confidence interval, 0.5-0.64). Disagreement was noted in the analysis of 77 stones. Conclusions: FT-IR analysis of kidney stones can overcome many limitations associated with chemical analysis

Diagnostic utility of anti-citrullinated protein antibody and its comparison with rheumatoid factor in rheumatoid arthritis

Objective: To assess the diagnostic utility of anti-citrullinated protein antibody (anti-CCP) in rheumatoid arthritis (RA) and compare it with rheumatoid factor (RF). Study Design: Analytical study. Place and Duration of Study: Section of Chemical Pathology, Department of Pathology and Microbiology and Medicine, the Aga Khan University, Karachi, from January to May 2010. Methodology: A review of medical records of patients presenting to the clinics with complaints of muscular or joint pains and who were tested for their serum anti-CCP was done. Inclusion criteria were presence of clinical synovitis in at least one joint and an absence of alternative diagnosis. Patients with arthralgia alone or with missing acute phase reactants information were excluded. Scoring and classification of RA was done using the 2010 RA Classification Criteria by the American College of Rheumatology (ACR). Results: Out of the 98 charts reviewed, ACR criteria showed 54 cases with RA. The mean age of the group was 46 ± 15 years, 82.7% being females. High titers of anti-CCP corresponded with the ACR scores. The sensitivity and specificity of anti-CCP and RF reactivity for the diagnosis of RA were 54.7% and 95.5% versus 59.3% and 88.4% respectively. Conclusion: Anti-CCP is useful for the diagnosis of RA due to its higher specificity as compared to RF and can predict disease severity
