RESUMEN
BACKGROUND: The association between somatic symptoms and psychiatric co-morbidities remains unexplored among patients with medically unexplained physical symptoms (MUPS) in Asian populations. This study aims to bridge this gap by investigating psychiatric morbidities and their determinants among patients presenting with MUPS in an Indian setup. METHODOLOGY: This cross-sectional study, conducted in the outpatient department (OPD) of a tertiary care hospital in India, assessed 200 patients diagnosed with MUPS. Assessment tools, such as the Somatic Symptom Scale (SSS-8), Presumptive Stressful Life Event Scale (PSLES), and Depression, Anxiety, and Stress Scale (DASS), were administered to collect data. RESULTS: The study examined patients (mean age 36.51±9.82 years), predominantly comprising females (67.5%), presenting with MUPS. Common presenting symptoms were general (96.3%), musculoskeletal pain (91.7%), and gastrointestinal symptoms reported by 81.7%. Medium somatic symptom severity (57%) was more prevalent in females. Prevalent psychiatric co-morbid conditions included depression (mild: 22.0%, moderate: 26.5%), moderate anxiety (41.5%), and moderate stress (26%). Strong associations were observed between the SSS-8 score and depression (χ²(6, N = 200) = 49.26, p < 0.001), anxiety (χ²(8, N = 200) = 37.90, p < 0.001), stress (χ²(6, N = 200) = 44.45, p < 0.001), and the experience of stressful life events (χ²(3, N = 200) = 6.5, p < 0.05). CONCLUSION: The study indicates an intertwined association between MUPS and psychiatric disorders. Individuals with MUPS commonly experience heightened anxiety and depression, emphasizing the complex interplay between somatic symptoms and emotional well-being. Consideration of environmental and social factors may be crucial for a comprehensive understanding.
RESUMEN
A substantial portion of patients presenting to healthcare settings exhibit physical symptoms lacking clear, demonstrable organic causes. Accurate assessment of symptom severity is crucial for documenting outcomes and establishing treatment efficacy. This systematic review and narrative synthesis aims to provide researchers with insights into available and validated tools for assessing medically unexplained physical symptoms (MUPS). It involved comprehensive searches across electronic databases, including PubMed, Wiley, and Cochrane, adhering to PRISMA and COSMIN guidelines. The study comprised two phases: Phase 1 systematically reviewed tools for assessing MUPS symptoms and severity, while Phase 2 conducted a narrative synthesis of their measurement properties, focusing on validity and reliability. Out of 14,459 records, 191 articles were identified, leading to the recognition of 16 validated tools for assessing MUPS symptoms and severity. Most tools demonstrated excellent internal consistency and structural validity. However, the majority lacked cross-cultural validity. The choice of tools for the assessment of MUPS will assist clinicians and researchers in determining the severity of MUPS and developing a tailored treatment plan to improve the physical and psychological functioning of these patients.
RESUMEN
INTRODUCTION: The review explores the potential benefits of cognitive retraining interventions in improving healthy lifestyle-related behaviours, and its possible use as an alternative or complementary approach to traditional weight loss interventions. METHOD: Studies were selected using different electronic databases (PubMed, Web of Science, Scopus, Embase), to identify RCTs published in the last 23 years on cognitive retraining interventions for weight loss. A total of 12 studies were finalized for systematic review and six for meta-analysis based on the inclusion criteria. The risk of bias was assessed by the two reviewers independently using the criteria outlined in the Joanna Briggs Institute Critical Appraisal Tool for RCTs. The R software was used to perform meta-analysis. RESULT: The overall effect estimates slightly favoured the intervention group, with a standardised mean difference (SMD) of -0.26 [95% CI (-0.58- 0.06) P < 0.05; I2 = 0.00%]. This suggests that although the effect was not statistically significant, cognitive retraining interventions may have a small effect on weight loss. The findings of the systematic review revealed that cognitive retraining interventions may be effective in modifying lifestyle behaviours and these changes may contribute in achieving and maintaining weight loss in the long run. CONCLUSION: Interventions exhibited a positive effect on weight loss. These interventions demonstrated promise in modifying lifestyle behaviours, suggesting a potential role in achieving and sustaining long-term weight loss. Further research is warranted to refine and validate these findings.

INTRODUCTION: Invasive mould infections (IMIs) are a leading cause of death in patients with compromised immune systems. Proven invasive mould infection requires detection of a fungus by histopathological analysis of a biopsied specimen, sterile culture, or fungal DNA amplification by PCR in tissue. However, the clinical performance of a PCR assay on blood samples taken from patients suspected of invasive mould disease has not been fully evaluated, particularly for the differential diagnosis of invasive aspergillosis (IA) and invasive Mucormycosis (IM). OBJECTIVES: To assess the diagnostic utility of our previously validated in-house real-time PCR in blood samples for diagnosis of invasive aspergillosis and mucormycosis in patients with suspected invasive mould infection. METHODS: All patients with suspected invasive mould infection were prospectively enrolled from May 2021 to July 2021. Conventional fungal diagnosis was performed using tissue and respiratory samples. In-house PCR was performed on blood samples and its diagnostic performance evaluated. RESULTS: A total of 158 cases of suspected invasive mould infection were enrolled in the study. The sensitivity and specificity of in-house PCR performed on blood samples was found to be 92.5% and 81.4% respectively for diagnosis of probable IA, and 65% and 84.62% respectively for diagnosis of proven and probable IM. It was also able to detect 3 out of 5 cases of possible IM where no other microbiological evidence of IM was obtained. CONCLUSIONS: This assay could be helpful in minimally invasive diagnosis of IMIs for patients in whom invasive sampling is not feasible, especially as a preliminary or screening test. It can help in early diagnosis, anticipating conventional laboratory confirmation by days or weeks. Possible correlation between fungal load and mortality can help in initiating aggressive treatment for patients with high initial fungal load.

INTRODUCTION: Obesity during perimenopausal transition can be attributed to various factors. Identifying these factors is crucial in preventing obesity and developing effective strategies to manage weight during this phase. This review aimed to systematically understand predictors of obesity during menopausal transition. METHODS: The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched databases like PubMed, Wiley Online Library, and Cochrane Reviews. Cohort and cross-sectional studies in English language assessing obesity among menopausal women were included. The methodological quality was assessed using Joanna Briggs Checklist for critical appraisal. Risk of Bias (RoB) was generated using Review Manager 5.4.1 (RevMan). Identified predictors were assessed for overall quality of evidence using adopted Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: This review encompassed 42 studies, (21 cross-sectional and 21 cohort) with sample ranging from 164 to 107,243 across studies. Higher parity( ≥ 3 children) emerged as a strong predictor of obesity across seven studies, with good-quality evidence. Lower physical activity was another predictor, supported by eight studies with good-quality evidence. Sociodemographic factors like lower education(<8 years or < than college degree), socioeconomic background, menopausal transition, and older age at menarche showed associations with weight gain, with moderate-quality evidence. Lifestyle factors (high-fat consumption, sedentariness, active smoking status, and psychological difficulties) also showed moderate-quality evidence. CONCLUSION: This review underscores the multifaceted factors associated with obesity during the perimenopausal transition. Identifying these factors will be helpful in prevention and management of obesity among these women.

BACKGROUND: Bronchoalveolar lavage (BAL) galactomannan (GM) is commonly used to diagnose Aspergillus-related lung diseases. However, unlike serum GM, which is measured in undiluted blood, BAL-GM is estimated using variable aliquots and cumulative volume of instillates during bronchoscopy. OBJECTIVE: Since different studies have reported varying diagnostic accuracy and cut-offs for BAL-GM in CPA, we hypothesized that the total volume of instillate and 'order/label' of aliquots significantly affects the BAL-GM values, which was evaluated as part of this study. PATIENTS & METHODS: We obtained 250 BAL samples from 50 patients (five from each) with suspected chronic pulmonary aspergillosis. BAL fluid was collected after instilling sequential volumes of 40 mL of normal saline each for the first four labels and a fifth label was prepared by mixing 1 mL from each of the previous labels. The GM level of each label was measured by PLATELIA™ ASPERGILLUS Ag enzyme immunoassay. This study measured the discordance, level of agreement, diagnostic characteristics (sensitivity, specificity and AUROC) and best cut-offs for BAL-GM in the different aliquots of lavage fluid. RESULTS: The study population, classified into CPA (28%) and non-CPA (72%) groups, based on ERS/ESCMID criteria (excluding BAL-GM) were not different with respect to clinico-radiological characteristics. The discordance of BAL-GM positivity (using a cut-off of >1) between the serial labels for the same patient ranged between 10% and 22%, while the discordance between classification using BAL-GM positivity (using a cut-off of ≥1) and clinic-radio-microbiological classification ranged between 18% and 30%. The level of agreement for serial labels was at best fair (<0.6 for all except one 'label'). The AUROC for the serial samples ranged between 0.595 and 0.702, with the '40 mL and the 'mix' samples performing the best. The best BAL-GM cut-off also showed significant variation between serial labels of varying dilutions (Range:1.01 - 4.26). INTERPRETATION: This study highlights the variation in BAL-GM measured and the 'positivity' between different 'labels' of aliquots of BAL, with the first aliquot and the mixed sample showing the best performances for diagnosis of CPA. Future studies should attempt to 'standardise' the instilled volume for BAL-GM estimation to standardise the diagnostic yield.

The diagnosis of chronic pulmonary aspergillosis (CPA) is established by combined clinic-radio-microbiological criteria. Out of the different microbiological criteria, a positive serology for Aspergillus-specific IgG levels is the cornerstone of diagnosis. Alternatively, other microbiological evidence are sometimes sought viz., positive Aspergillus antigen (broncho-alveolar lavage fluid, i.e., BALF galactomannan ≥ 1.0), histopathological demonstration of the fungi following lung biopsy or resection, demonstration of hyaline septate hyphae in direct microscopy resembling Aspergillus spp. or its growth on a respiratory specimen. However, the exact roles of BALF- GM and the newer BALF-PCR have not been confirmed by studies till date. This study enrolled 210 patients with suspected CPA. Of the participants, 88 patients met the criteria for CPA, whereas 122 patients had an alternative diagnosis. The sensitivity-specificity of AsperGenius® PCR and "in-house" PCR were 52.27(36.69-67.54) %-33.78 (23.19-45.72) % and 36.36 (22.41-52.23) %-39.19 (28.04-51.23) % respectively. The sensitivity/specificity of BALF (> 1.0) and serum galactomannan (> 1.0) were 46.55% (33.34-60.13)/64.08% (54.03-73.3) and 29.82% (22.05-37.6)/86.84% (81.1-92.59) respectively. The optimal cut-off values for BALF-Galactomannan and serum galactomannan in diagnosing CPA were found to be 0.69 (sensitivity: 64%; specificity: 53%) and 0.458 (sensitivity: 67%; specificity: 64%) respectively. This results of this study suggests that Aspergillus PCR from BAL may not be a good "rule-in" test for diagnosing CPA. While the performances of GM in BAL and serum may be better than PCR, it should be best used in conjunction with other clinical, radiological, and other microbiological characteristics.

BACKGROUND: Approximately one-fourth of individuals who seek treatment in outpatient medical settings have Medically Unexplained Physical Symptoms (MUPS), a prevalent medical ailment. Patients with MUPS have a considerable functional impairment, and a lower quality of life, and may also have co-occurring psychiatric conditions. MATERIALS AND METHODS: Eleven Focus Group Discussions (FGDs) (four virtual and seven face-to-face) were conducted with patients, caregivers, and healthcare professionals in 2021 in a tertiary care hospital in New Delhi. Thematic analysis was carried out using QSR Nvivo software. RESULTS: A total of 36 participants were recruited in the study, including patients with MUPS (n = 12), caregivers (n = 10), and healthcare professionals (n = 14) dealing with the patients of MUPS. Three themes were identified: burden of MUPS, symptom profile of patients with MUPS, and psychological profile of patients with MUPS. These were further categorized into eight sub-themes: prevalence, symptoms, course of illness, improvement with treatment, duration of symptoms, attribution of symptoms, psychological impact, and coping strategies. CONCLUSION: The study helped us to gain insight into the characteristics and experiences of patients, caregivers, and healthcare professionals dealing with MUPS in an Indian setup. Greater awareness of MUPS and training of care providers about the occurrence, management, and referral of MUPS can be beneficial.
RESUMEN
OBJECTIVE: To develop and validate questionnaires to assess the behavioral, psychosocial, and environmental predictors of successful weight loss outcomes. DESIGN: Mixed method study. Questionnaires were developed using 5 steps: item generation by literature review and preexisting questionnaires, expert evaluation, pilot testing, factor analysis, and internal consistency. SETTING: Adults with obesity recruited via web-based survey hyperlink. PARTICIPANTS: One hundred participants with a mean body mass index of 28.7 ± 4.4 kg/m2. VARIABLES MEASURED: The questionnaires were generated using 221 items. Establishing content, face and construct validity, and internal consistency. ANALYSIS: Content validity was analyzed using content validity index and content validity ratio, internal consistency through Cronbach α (CA), and structural validity by factor analysis via principal varimax rotation. RESULTS: All three questionnaires had good content validity. The Behavioral Predictor Questionnaire had good internal consistency (CA, 0.7) and excellent structural validity (69.7%). Psychosocial Predictors Questionnaire (CA, 0.8, 67.5%) and Environmental Predictors Questionnaire (CA: 0.8, 72.2%) had excellent internal consistency and structural validity. CONCLUSION AND IMPLICATION: Questionnaires seem to be practical, valid, and reliable tools for baseline assessment of individual-specific factors related to weight loss success.

Tuberculosis (TB) is quite prevalent in developing countries, with an ever-rising incidence of extrapulmonary cases. TB of bones and joints is quite challenging to diagnose. Most spinal TB lesions localize at the thoracic and lumbar levels; cervical lesions are a rarity. Hence, most neck pains are labelled cervical spondylosis as the symptomatology of cervical spine tuberculosis (CTB) remains unclear. A 38-year-old male had long-standing neck pain for six months, not associated with any focal neurological deficit, nausea, vomiting, or blurred vision. After the initial evaluation by local practitioners, the pain was, as usual, attributed to cervical spondylosis and conservatively managed. However, his pain worsened, and he ultimately came to us with altered mental status. In reality, he had CTB, which later complicated to life-threatening disseminated TB with intracranial and pulmonary involvement, and he could only survive after prolonged ICU care. Even mild cervical pain should not be neglected and must undergo proper evaluation. We should consider CTB in the differential diagnosis of chronic neck pain, especially in countries where TB is endemic.
RESUMEN
BACKGROUND: Coronavirus disease 2019 (COVID-19) causes abnormalities in the hemostatic system, collectively known as COVID-associated coagulopathy. The dynamics of clot formation are best discerned by whole-blood viscoelastic tests, such as thromboelastography (TEG). We aimed to assess the various abnormalities seen on TEG and explored the predictors of outcomes in these patients. METHODS: Thromboelastography was performed for 28 patients with COVID-19 using an automated thromboelastogram. The hemostatic condition was categorized as hypercoagulable in 17 (63%), hypocoagulable in 2 (7%), and normal in 8 (30%) based on TEG variables, such as reaction time , time until clot reaches a fixed strength, alpha angle, maximum amplitude, and clotting index. Laboratory parameters and clinical outcomes were compared between hypercoagulable and normal groups. RESULTS: Twenty-seven patients with a median age of 50 years (interquartile range, 40-60 years), male-to-female ratio of 0.9:1, median C-reactive protein of 25.7 (10.9-108.8) mg/L, serum ferritin of 693 (317-1031) µg/L, and albumin 2.9 (2.6-3.3) g/dL were included. The median prothrombin time/international normalized ratio and activated partial thromboplastin time were within normal range in the hypercoagulable and normal groups. The severity of COVID-19 was mild in 6 (22.2%), moderate in 2 (7.4%), and severe in 19 (70.4%) patients. Twenty-eight-day mortality among patients with hypocoagulable and hypercoagulable states was higher than normal coagulation status. (log-rank test, P = .002). CONCLUSIONS: Hypercoagulable state, together with a severe inflammatory state, is common in patients with COVID-19, despite thromboprophylaxis. TEG assesses coagulation status better than conventional coagulation tests. Coagulation abnormalities are associated with poor outcomes.
RESUMEN
BACKGROUND: Transfusion of ABO-compatible single donor platelets (SDP) is preferable for better outcomes over group switchover SDP. The use of SDP containing ABO-incompatible plasma is associated with a risk of allergic and acute hemolytic transfusion reactions. Moreover, high titer O group donors SDP impose a further threat to patient safety. Platelet additive solution (PAS) is used worldwide for the storage of platelets which reduces plasma volume available in SDP. SSP + (Macopharma) is one such PAS which can provide improved availability, logistical management, decrease wastage, and improvement in patient safety. The aim of this study was to assess the feasibility of using PAS to obtain low titer SDP units which can be utilized across a larger patient population and to study quality control parameters of these units. MATERIALS AND METHODS: The study was performed in the department of Transfusion Medicine from June 2017 to January 2018 after clearance from the Institutional Review Board. The study design comprised two cohorts (A and B). In cohort A, the temporal trend of in-vitro changes in the quality parameters was tested and analyzed for PAS modified and unmodified products on days 1, 5 and 7. In cohort B, the original plasma from the SDP donors of all blood group donors except the AB group was tested for antibody titers before (prepreparation) and after modification (postpreparation) by PAS. RESULTS: In cohort A, in the control group, there was a significant change in the mean platelet volume, potassium, and bicarbonate levels from day 1 to day 7, whereas no significant change in the biochemical parameters was noted in the study group where PAS was used. In cohort B, on comparing the anti-A and anti-B, before and after modification of SDP with PAS, there was a significant reduction in the median titers across all the groups studied. CONCLUSION: PAS added SDP is an efficient strategy to reduce the ABO-antibody levels significantly. PAS added SDP also helps in the better inventory management of available groups.
RESUMEN
AIMS: To evaluate the dose-effect association between COVID-19 vaccination and probability of turning RT-PCR positive and to assess the correlation between disease severity and vaccination status. METHODS: A single centre cross-sectional study was conducted amongst 583 individuals presenting to COVID-19 testing clinic and 55 hospitalized COVID-19 patients. Vaccination status was assessed by the number of doses and duration since the last dose. Disease severity was evaluated by the requirement of hospitalisation and ICU admission/death. The association between the vaccination status and development of disease and its severity were statistically analyzed. RESULTS: The mean age of the population was 36.6 years and 82.6% had no comorbidities. The odds of turning RT-PCR positive was 0.17(95% CI: 0.11-0.27) among the clinical suspects who had taken both doses of the vaccine at least 14 days before (fully vaccinated). The odds of hospitalisation was 0.12(95% CI: 0.03-0.45) and ICU admission/death was 0.07(95% CI: 0.01-0.36) among fully vaccinated individuals. The protective role of vaccination was observed to start 14 days after receiving the first dose. CONCLUSIONS: COVID-19 vaccination provides dose-dependent protection against the development of the disease. It also lowers the risk of hospitalisation and ICU admission/death in RT-PCR positive patients in a dose-dependent manner.

BACKGROUND AND AIMS: COVID-19 is expected to have a significant impact on the socio-behavioural aspect of citizens' lives, although the effects are expected to manifest differently in different population groups. The current study was conducted to assess the socio-behavioural impact of COVID-19 among the general population across India between the first and the second wave of pandemic. METHODS: A web-based cross-sectional study was conducted from 15th March -25th March 2021 using a pre-validated validated questionnaire upon the general population using e-survey, telephonic and face-to-face interview. The participants were recruited from the different regions of India by the purposive and snowball sampling technique following the principle of maximum diversity. Appropriate statistical tests were applied to study the association between the various sociodemographic variables and different behaviours. RESULTS: A total of 1079 responses were analysed for the study. Almost half of the participants feared contracting the COVID-19 infection. Overall, female participants, elderly people (more than 60 years of age) and urban dwellers reported a greater fear in the survey. More than half of the participants (53.39%) reported significant difficulties due to home confinement. People have become more inclined to adopt healthy lifestyles. There are mixed responses in the area of following preventive practices. CONCLUSION: People have a significant amount of fear and anxiety related to the pandemic, leading to several social and behavioural changes that might have a considerable impact on their everyday lives.

BACKGROUND AND AIMS: The success of the COVID-19 vaccination program is dependent on people's knowledge and attitude regarding the vaccination program. Higher vaccine acceptance can be ensured by strengthening the facilitators and limiting the barriers being observed among the general population. MATERIAL AND METHODS: Indexed study is a cross-sectional web-based survey using a pre-validated questionnaire to assess knowledge, barriers and facilitators of COVID-19 vaccine and vaccination programme administered on adults across India using a Google online survey platform. RESULTS: A total of 1294 responses (age: 38.02 ± 13.34 years) were collected. Most of the participants had limited knowledge regarding the eligibility of vaccines in vulnerable population groups such as people with allergies (57.89%) and immune-compromised patients (62.98%), pregnant and lactating women (41.89%) and patients with chronic illness (34.78%). Older participants (>45 years) were more willing to take the COVID-19 vaccine (p < 0.001) as they believed the vaccine is not harmful and considered it as societal responsibility. Younger participants (<45 years) and those residing in urban settings raised concerns on the availability of the vaccine and authenticity of the vaccine (p < 0.001). CONCLUSION: There is a scope for improvement in people's knowledge regarding COVID-19 vaccine and the vaccination programme by addressing the barriers and facilitators which can improve the participants' turnover at vaccination centres.

BACKGROUND AND AIMS: There seems to be hesitation in the general population in accepting COVID 19 vaccine because of associated myths and/or misinformation. This study is dedicated to develop and validate a tool to interpret vaccine acceptance and/or hesitancy by assessing the knowledge, attitude, practices, and concerns regarding the COVID vaccine. MATERIAL AND METHODS: Mixed methods study design was used. In phase 1, the questionnaire was developed through literature review, focus group discussion, expert evaluation, and pre-testing. In phase 2, the validity of the questionnaire was obtained by conducting a cross-sectional survey on 201 participants. The construct validity was established via principal component analysis. Cronbach's alpha value was used to assess the reliability of the questionnaire. RESULTS: The 39-item questionnaire to assess the knowledge, attitude, practices, and concerns regarding the COVID-19 vaccine was developed. The Cronbach's alpha value of the questionnaire was 0.86 suggesting a good internal consistency. CONCLUSION: The developed tool is valid to assess the knowledge, attitude, practices and concerns regarding the COVID-19 vaccine acceptance and/or hesitancy. It has the potential utility for healthcare workers and government authorities to further build vaccine literacy.

The accurate estimation of ABO antibody titers is of the utmost importance in organ transplants involving ABO incompatibility. We aim to compare five different methods of titration and analyze the data. Samples of 48 O group blood donors who donated during the month of December 2015 to January 2016 in our institution were subjected to ABO antibody titration by five different methods: immediate spin (IS) tube titer, antihuman globulin phase tube titer, Coomb's gel card titer, gel card titer after dithiotreitol (DTT) treatment of plasma, and the solid phase red cell adherence method. The mean number of titer serial dilution steps in the different titer estimation methods was compared using the paired t-test and McNemar test. A correlation between the methods was tested using Spearman's rho and kappa statistics. The median antiglobulin (AHG) phase tube titers were found to be the highest anti-A (128) and anti-B (192) titers. Significant differences in the ABO antibody titer readings among the five different methods were noted. Titers were reduced by DTT treatment in nearly 50% samples tested for both anti-A and anti-B titers. Average agreements between the DTT-applied AHG phase gel card titers and the solid phase red cell adherence (SPRCA) titers was observed for anti-A (κ = 0.473) and anti-B (κ = 0.530). The AHG phase tube and gel cards titers showed poor agreements. There are differences in the interpretability of the ABO antibody titer among different techniques. Consistent and uniform application of the method for titration throughout the treatment of a patient is highly essential.

BACKGROUND: Alloantibodies may be detected in blood donors who have either been transfused previously or female donors with previous obstetric events. These antibodies can occasionally cause severe transfusion reaction, if a large amount of plasma or whole blood is transfused, as in massive transfusions and pediatric patients. AIMS: The present study aims to assess the prevalence of red cell antibodies in healthy blood donors at a tertiary care hospital-based blood bank in India. MATERIALS AND METHODS: A total of 82,153 donor samples were screened for irregular red cell antibodies between January 2012 and December 2015 at the Department of Transfusion Medicine, Indraprastha Apollo Hospitals, New Delhi. Antibody screening was performed by solid phase method using Immucor Capture-R ready screen (pooled cells) on fully automated immunohematology analyzer Galileo Neo (Immucor Inc., Norcross, GA, USA). Positive tests were further confirmed using Capture-R ready screen (4 cell panel). Advanced investigations to identify the antibody/ies were performed on confirmed positive samples. Antibody identification was conducted using various cell panels (Immucor Capture-R Ready-ID, Panocell-10, Ficin Treated). An advanced technique such as adsorption and elution was performed as per requirement. RESULTS: Screening with pooled cells and 4 cell panel was positive in 227 donors (0.27%), 150 of these donors had autoantibodies, 1 had autoantibodies with underlying alloantibody anti-Jka (0.001%), and 76 had alloantibodies (0.09%) alone in their plasma. Anti-M was the most common antibody (43 donors) identified, followed by anti-D (21 donors). Anti-N was detected in 4; anti-Jka, anti-C, and anti-E in two donors each followed by anti-P1 and anti-Leb in 1 donor. CONCLUSION: Antibodies against red cells can be present in healthy donors detection of which is important in providing safe blood to the patient. The prevalence of red blood cell antibody in healthy donors in this study was found to be 0.27%, while the prevalence of alloantibodies was 0.09%. The majority of alloantibodies were anti-M (56.57%) and anti-D (27.63%).
