Medical laboratory staff satisfaction and their perspective on the role of health institutions to combat COVID-19 pandemic.

OBJECTIVE: To assess the facilities and challenges encountered in the clinical laboratories, satisfaction of the medical laboratory staff (MLS) toward their profession and their views on the role of related health institutions during the first wave of the Coronavirus Disease 2019 (COVID-19) pandemic in Nepal. METHODS: A web-based cross-sectional study was conducted among registered MLS in Nepal. Data were collected using a structured self-reported questionnaire on the Google Docs platform. RESULTS: A total of 301 respondents were enrolled in the study; of which 180 were male and 121 were female. Of the 301 respondents, a lack of infrastructure was reported by 241 (80.1%), a lack of skill development training by 204 (67.8%), limited availability of diagnostics kits by 151 (50.2%), overburdened by the workload by 142 (47.2%) and difficulty in sample management by 129 (42.9%). A total of 244 of 301 respondents (81.1%) believed that stakeholder institutions should collaborate with the government during the pandemic. The level of satisfaction during the pandemic (130 of 301; 43.19%) was found to have decreased compared with before the pandemic (203 of 301; 67.4%). CONCLUSION: MLS were not fully satisfied with the available resources during the pandemic.

Knowledge, practice and psychological symptoms among medical laboratory staff during COVID-19 pandemic in Nepal: An online based survey.

INTRODUCTION: Despite several attempts to control COVID-19, there was a continuous rise in the number of cases, and this has left questions unanswered on the availability of health resources in Nepal. Here, we tried to assess the level of knowledge, practice and psychological symptoms among medical laboratory staff. METHODS: An online survey was conducted in February 2021. A total of 301 completely filled responses were used to assess knowledge, practice and psychological distress. R-language software was used for data analysis and p-value less than 0.05 was considered statistically significant. RESULTS: Of the total 301 respondents, 180 (59.8%) were male and 121 (40.2%) were female. The average score of knowledge obtained in this study was 32.4 ± 5.7 on a 56-point scale. Knowledge level was significantly different among age-groups (p-value - 0.034). The average practice score obtained was 2.25 ± 0.91 on a 4-point scale. More than one psychological distress symptom was observed in nearly half (41.5%) of the participants. CONCLUSION: We conclude that medical laboratory staff in Nepal has satisfactory levels of knowledge and practice and, larger number of them has psychological distress. The study recommends further improvement in an effective information flow system, regular training, social security and psychological support.

Establishment of reference range of CD4 T-lymphocyte in healthy Nepalese adults.

OBJECTIVE: CD4 T lymphocytes are the most widely used cellular markers to assess the course of HIV infection, clinical staging and, monitoring the effect of antiretroviral therapy. The regional reference range for Eastern, Central and Western development region of Nepal had already been established whereas the same was still lacking in Mid-western and Far-western development region. The objective of this study was to establish reference range of CD4 T lymphocyte in the remaining two development regions and finally the national reference range using data from previous study. RESULTS: The average values (mean ± SD) of CD4 and CD3 T cell in present study was (819 ± 294) cells/µl and (1546 ± 532) cells/µl, respectively. The absolute CD4 T cell (914 ± 303) and CD3 T cell (1671 ± 560) count in female were significantly higher than those from male, CD4 (757 ± 270) and CD3 (1465 ± 499) (p value-0.000). National reference value of CD4 was determined to be (798 ± 335) cells/µl for healthy Nepalese adults.

Extended-Spectrum ß-Lactamase (ESBL) Genotypes among Multidrug-Resistant Uropathogenic Escherichia coli Clinical Isolates from a Teaching Hospital of Nepal.

Urinary tract infections (UTI) represent the most common bacterial infections among patients visiting outpatient clinics of healthcare centers in Nepal. However, treatment of such infections is compounded by emergence and spread of multidrug-resistant uropathogens associated with extended-spectrum ß-lactamases (ESBLs). In this study, we aimed to investigate the burden of antimicrobial resistance and occurrence of ESBL genes among clinical isolates of uropathogenic Escherichia coli at a tertiary care teaching hospital of Nepal. During the study period, we processed a total of 1,626 urinary tract specimens, isolated significant bacterial pathogens, and investigated their antimicrobial susceptibilities. Escherichia coli (n = 154), the predominant pathogen associated with UTI, was further investigated for the existence of ESBL enzymes by using conventional phenotypic as well as molecular approaches. Among suspected cases of UTI, we found that 15.2% were having UTI and female patients of the reproductive age group were more affected (p < 0.05). Escherichia coli (154, 62.1%) was the key uropathogen, and majority (∼64.9%) of them were multidrug resistant (MDR). Among MDR E. coli isolates, 40.3% were producing extended-spectrum ß-lactamases (ESBLs). bla-TEM (83.8%), bla-CTX-M (66.1%), and bla-SHV (4.8%) were common ESBL genotypes. Nitrofurantoin, gentamycin, and imipenem were the most effective antibiotics for ESBL-producing Escherichia coli isolates. It indicates that the high rates of multidrug-resistant Escherichia coli are frequent causes of UTI in our hospital. Nitrofurantoin and aminoglycosides are the most useful first-line drugs to be used in the cases of UTI. We recommend the regular investigation of drug resistance among all isolates and develop a useful antibiotic prescription policy in our country.

Distribution of Hemoglobinopathy in Nepalese Population.

BACKGROUND: Sickle cell and thalassemia are the inherited disorders of globin chain synthesis, and are the most common monogenic disease worldwide. This study aims to find the distribution of hemoglobinopathies (sickle cell and thalassemia) cases in Nepal using laboratory based data. METHODS: A retrospective study was carried out at five different sites of Nepal Government that uses capillary electrophoresis for screening of hemoglobin disorders from January 2019 to March 2019. All the cases diagnosed positive for hemoglobinopathy till December 2018 were collected from laboratory record at each sites, and analyzed using Statistical Package for Social Sciences (SPSS version 20.0). RESULTS: Out of total 4018 patients tested during the period in all five different sites, 1470 were diagnosed positive for hemoglobinopathy. Sickling disorder was the most predominant hemoglobinopathy followed by ?-thalassemia. Province 5, province 6 and province 7 were mostly affected by sickling disorder while the other provinces by ?-thalassemia. CONCLUSIONS: Sickle cell is the commonest cause of hemoglobinopathy followed by B thallesmias in Nepalese population. Sickle cell is more concentrated towards western part of Nepal and especially in Tharu ethnic population. In contrast, the distribution of ?-thalassemia is found throughout the country and among all ethnic groups of population.

Overview of seasonal influenza and recommended vaccine during the 2016/2017 season in Nepal.

BACKGROUND: Influenza is a highly contagious viral respiratory infection caused by influenza viruses whose epidemic and pandemic have resulted in significant morbidity and mortality. The annual epidemic of influenza results in an estimated 3-5 million cases of severe illness and about 290000-650000 deaths globally. The vaccination program has been successful to control the epidemic however, it further needs improvement. This study was aimed to investigate the types of influenza viruses prevailing in Nepal during 2016 and, to match the recommended vaccine for use during the same season. METHODS: A descriptive cross sectional study was carried out at National Public Health Laboratory, Kathmandu, Nepal for the period of one year (Jan-Dec 2016). A total of 1683 throat swab specimen was collected from patients of different age group referred to NPHL for influenza testing. The specimen was primarily stored at 4 °C and processed using ABI 7500 RT PCR system for the identification of influenza viruses. RESULTS: Of the total 1683 patients suspected of having influenza infection, influenza viruses were isolated from 614 (36.5%) patients with male predominance. The highest number of infection was caused by influenza A/H3 strain (51.0%) followed by influenza B (40.4%) and influenza A (H1N1) pdm09 (8.6%). Two peaks of infection were observed during the year 2016. The widely available trivalent vaccine during the season did not match the prevailing strain because of the dominance of B/Yamagata lineage over B/Victoria lineage. CONCLUSION: We concluded that Nepal experiences semiannual cycle of influenza infection, firstly during the month of January-February and secondly during the month of July-August. The vaccine to be introduced in Nepal need to be decided by national authority based on prevailing influenza types to confer effective immunization.

Evaluation of Five International HBV Treatment Guidelines: Recommendation for Resource-Limited Developing Countries Based on the National Study in Nepal.

Hepatitis B virus (HBV) infects the liver, causing cirrhosis and cancer. In developed countries, five international guidelines have been used to make a decision for the management of patients with chronic HBV infection. In this review, since the guidelines were established by clinical and epidemiological data of developed countries, we aimed to evaluate whether (1) HBV patient profiles of developing countries are similar to developed countries, and (2) which guideline can be applicable to resource-limited developing countries. First, as an example of the most recent data of HBV infections among developing countries, we evaluated the national HBV viral load study in Nepal, which were compared with the data from other developing countries. In Nepal, the highest number of patients had viral loads of 20-2000 IU/mL (36.7%) and belonged to the age group of 21-30 years; HBV epidemiology in Nepal, based on the viral loads, gender, and age groups was similar to those of not only other developing countries but also developed countries. Next, we reviewed five international HBV treatment guidelines of the World Health Organization (WHO), American Association for the Study of Liver Diseases (AASLD), National Institute for Health and Care Excellence (NICE), European Association for the Study of the Liver (EASL), and Asian Pacific Association for the Study of the Liver (APASL). All guidelines require the viral load and alanine aminotransferase (ALT) levels for decision making. Although four guidelines recommend elastography to assess liver cirrhosis, the WHO guideline alternatively recommends using the aspartate aminotransferase (AST)-to-platelet ratio index (APRI), which is inexpensive and conducted routinely in most hospitals. Therefore, in resource-limited developing countries like Nepal, we recommend the WHO guideline for HBV treatment based on the viral load, ALT, and APRI information.

Late Response of Antiretroviral Therapy in an HIV-1-Infected Patient due to Hepatitis B and C Coinfections: The First Case Report in Nepal.

AIM: Dual coinfection of HCV and HBV in HIV-1-infected population is a leading cause of morbidity and mortality. Also, they share routes of HIV transmission; however, it might be associated with an independent factor like injecting drug use for HCV and unsafe sex for HBV. This case report suggests that hepatitis virus coinfection may lead to late response of antiretroviral therapy (ART) in HIV-1 patients. PATIENTS AND METHODS: A 49-year-old male patient visited for the routine follow-up investigation at the National Public Health Laboratory (NPHL), Teku, Nepal. He was an HIV-1-positive injecting drug user (IDU) co-infected with HCV and HBV. The patient was under ART as per the National HIV Testing and Treatment Guidelines 2017, Nepal. Further, serological and viral load testing was performed for confirmation and monitoring therapy, respectively. RESULTS: It is the first report that highlights the dual coinfection of HCV and HBV in an HIV-1 patient from Nepal. The follow-up investigation shows improved response to ART with an increase in CD4+ cells. However, detectable viral loads indicated for a late response might be due to effects of coinfections or viral interactions. CONCLUSIONS: Dual coinfection is rare; however, it is more serious with poorly defined epidemiology and evolution in an HIV-1-infected population. Thus, universal screening of HBV or/and HCV coinfection in HIV-1-infected population requires immediate implementation for true prevalence, proper management, and early intervention.

Metabolic syndrome and biochemical changes among non-alcoholic fatty liver disease patients attending a tertiary care hospital of Nepal.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is mutually and bidirectionally linked with metabolic syndrome (MetS) of which it is both the cause and the consequences. Worldwide, 6.3 to 33% of the general populations are estimated to suffer from the disease with even higher prevalence in the group sharing metabolic co-morbidities. Hence, this study aims to recognize various risk factors including metabolic components and blood parameters to predict the possible incidence of the disease. METHODS: Total of 429 (219 NAFLD and 210 control) subjects were conveniently selected for study during the period of 9 months. Diagnosis of non-alcoholic fatty liver disease was done by liver imaging and based on liver enzymes. Assessment of metabolic syndrome was done by International Diabetic Federation (IDF) and National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. All biochemical and hematological parameters and liver enzymes were estimated by using standard guideline. Mean comparison of quantitative data in different groups were performed using analysis of variance (one-way ANOVA). Risk estimation of NAFLD associated with each character was verified by Chi-square test. RESULTS: There was significant high levels of body mass index (BMI), waist circumference (WC) and lipid profiles in NAFLD patients in comparison to control population (p < 0.001). Further, according to the NCEP ATP III criteria, 13.6% of NAFLD were present with MetS where risk estimate was significant (OR = 2.15). Whereas, other criteria (IDF) for MetS showed higher frequency (30.1%) with higher risk (OR = 29.75) for the presence of MetS in NAFLD patients. The change in triglycerides (TG) and HDL-C (high density lipoprotein cholesterol) was also statistically significant in different grades of NAFLD. High risk for NAFLD was associated with existing co-morbid conditions like cardiovascular risk patients (3.18 times) followed by obese patients (1.72 times) and Diabetes Mellitus patients (1.68 times) at a significant level. CONCLUSION: The result of this study suggests that there is an increased prevalence of all the components of MetS and significant changes in biochemical markers in cases of NAFLD. Timely diagnosis would help in delaying its complications and co-morbidities.

Sustained Viremic Control in HIV-Infected Patient: Case Report from Nepal.

A case of human immunodeficiency virus (HIV) infection is described from Nepal with constant maintenance of CD4 count and HIV-RNA level below the lower detection threshold for more than ten years. The case was diagnosed of HIV positive in the year 2008. He had his viral load estimation performed every year since then which was always below lower detection limit and remained healthy without treatment. The patient also had not any kinds of opportunistic infection till date. He is married now and has not transmitted the disease to his wife.

Evaluating the Trends of Bloodstream Infections among Pediatric and Adult Patients at a Teaching Hospital of Kathmandu, Nepal: Role of Drug Resistant Pathogens.

Bloodstream infections (BSIs) are among the significant causes of morbidity and mortality for patients of all age groups. However, very little is known about the trends of bacterial bloodstream infections and antimicrobial susceptibilities among pediatric and adult population from Nepal. In this study, we have investigated the different etiological agents responsible for bloodstream infections among pediatric and adult patients and the role of drug resistant organisms in these infections at a tertiary care teaching hospital of Kathmandu, Nepal. A total of 3,088 blood culture specimens obtained from pediatric and adult patients suspected to have bloodstream infections were processed by standard microbiological methods. Significant bacterial pathogens were identified by morphological, biochemical, and serological methods as suggested by American Society for Microbiology. In vitro antimicrobial susceptibility testing was performed by Kirby-Bauer disk diffusion method and interpreted according to the guidelines of Clinical and Laboratory Standards Institute. Overall, incidence of bloodstream infections among the suspected patients was 7.48%. Pediatric patients (n = 90, 9.37%) were the significant subgroup of patients affected with bloodstream infections compared to adults (p < 0.05, CI-95%). Gram positive (n = 49, 54.4%) bacteria in pediatric and gram negative bacteria (n = 141, 78.7%) in adult patients were the most common isolates for BSI. Staphylococcus aureus (n = 41, 45.6%) in pediatric patients and Salmonella enterica (n = 40, 28.3%) in adult patients were the leading pathogens. Trends of antimicrobial resistance among isolated bacterial strains were significantly high in adults compared to pediatric patients. Methicillin resistant Staphylococcus aureus (MRSA) (31.4%), extended spectrum beta-lactamase (ESBL) (12.5%), and metallo-beta-lactamase (MBL) (3.9%) producing gram negatives were major resistant strains. Our study shows higher rates of bloodstream infections in pediatric patients compared to adult patients. Alarming rates of antimicrobial resistance among blood culture isolates is a serious issue. Prompt and accurate diagnosis and rational antimicrobial therapy are extremely needed.

Shigellosis Caused by CTX-M Type ESBL Producing Shigella flexneri in Two Siblings of Rural Nepal: First Case Report from the Country.

Shigellosis is an acute infectious disease characterized as severe bloody diarrhea (dysentery) and is accountable for a significant burden of morbidity and mortality especially in children under the age of 5 years. Antimicrobial therapy is required in the cases of severe dysentery associated with Shigella. However, emergence of multidrug resistant (MDR) strains of Shigella spp. over the last two decades has restricted the use of common therapeutic antimicrobials. In MDR strains, the third-generation cephalosporins have been used for the treatment, but, unfortunately, emerging reports of enzyme mediated ß-lactam resistance among Shigella isolates from various parts of the world have greatly compromised the therapy of pediatric dysentery. In Nepal, drug resistant strains of Shigella spp. have been reported, but MDR and extended spectrum ß-lactamase (ESBL) producing strains were previously unknown. Here, we report two Shigella flexneri isolates harboring ESBL genotype-CTX-M associated with acute dysentery in two siblings which were presented and treated in a tertiary care teaching hospital of Kathmandu, Nepal.

Bacteremia caused by a rare pathogen - Chromobacterium violaceum: a case report from Nepal.

Chromobacterium violaceum is a gram negative saprophytic bacterium, prevalent in tropical and subtropical climates. Infections caused by C. violaceum are very uncommon, yet it can cause severe systemic infections with higher mortality when entered into the bloodstream through open wound. A case of symptomatic bacteremia in a woman caused by C. violaceum was identified recently at a tertiary care teaching hospital in Nepal. Timely diagnosis by microbiological methods and rapid administration of antimicrobials led to a successful treatment of this life-threatening infection in this case. From this experience, we suggest to include this bacterium in the differential diagnosis of sepsis, especially when abraded skin is exposed to soil or stagnant water in tropical areas. The precise antimicrobial selection and timely administration should be considered when this infection is suspected.
