ABSTRACT

Objective Sepsis is a major global health issue due to its high death and morbidity rates. To avoid the negative effects of sepsis and decrease mortality, it is vital to diagnose and treat it as soon as possible. Blood cultures can take up to 2 days to give result, and they are not always reliable. According to recent studies, neutrophil CD64 expression might be a sensitive and specific option for assessing sepsis. This study aimed to evaluate the diagnostic performance of a flow cytometry analysis for the expression of neutrophil CD64 in sepsis and its comparison with other standard tests in a tertiary care center. Materials and Methods Prospective analysis on 40 blood samples from suspected sepsis patients admitted to intensive care units with criteria for the systemic inflammatory response syndrome on presentation was performed for expression of neutrophil CD64, C-reactive protein, procalcitonin, and complete blood count. Ten healthy volunteers were also enrolled in this prospective study. The laboratory results were compared in different groups. Results The neutrophil CD64 had the highest diagnostic value to differentiate between patients of sepsis and nonsepsis groups with a sensitivity of 100% (95% confidence interval [CI]: 77.19-100%) and 100% (95% CI: 55.32-86.83%); specificity of 90.00% (95% CI: 59.58-99.49%) and 87.24% (95% CI: 66.69-99.61%); and likelihood ratio of 10.00 and 7.84, respectively. Conclusion The neutrophil CD64 expression provides a more sensitive, specific, and novel marker for the early detection of sepsis in critically ill patients.

ABSTRACT

Background COVID-19 is a rapidly spreading pandemic caused by SARS-CoV-2. India experienced a second wave peak in mid of April 2021, and it emerged as a medical crisis. This study was taken up to show if the hematological and peripheral blood changes can be used as a readily available tool to demarcate the patients needing ICU care so that the ICU can be utilized more prudently.  Material and method One hundred reverse transcription-polymerase chain reaction (RT-PCR) confirmed cases of COVID-19, 50 each from ICU and non-ICU wards, were included in this observational study. At the time of admission blood sample was collected for evaluation of hematological parameters. Results We noted that 74% of patients admitted in ICU were males and 28% were more than 60 years of age. In ICU patients, the absolute neutrophil count (ANC) was significantly raised when compared to non-ICU cases (p=0.023). The nadir absolute lymphocyte count (ALC) was 0.11x109/L in ICU patients and 0.95x109/L in non-ICU patients. There was a significant increase in neutrophil-lymphocyte ratio (NLR; p<0.001) in ICU patients with a proposed cut-off value of 7.73. Platelet-lymphocyte ratio (PLR) was also raised in ICU patients; however, this increase was not significant (p= 0.623). The proposed cut-off value of PLR is 126.73. A significant reduction in a lymphocyte-monocyte ratio (LMR) was observed in ICU patients when compared to non-ICU cases (p<0.001). Thrombocytopenia was more commonly seen in ICU patients; however, this was not statistically significant. Viral-induced cytopathic effects like plasmacytoid lymphocytes with cytoplasmic granules, the presence of toxic changes in neutrophils, and large-sized platelets were commonly observed in ICU patients. Conclusion Our results suggest that hematological parameters like ANC, absolute lymphocyte count (ALC), platelet count, NLR, PLR, and peripheral smear changes are simple assessment factors that can serve as indicators for the severity of COVID-19 and will demarcate the patients who need ICU-care. This will help in the judicious use of ICU facilities for patients who are actually in need.

ABSTRACT

BACKGROUND/OBJECTIVES: In, India coronavirus disease (COVID-19) cases are on the rise in terms of the total number of cases. Findings on clinical and hematological parameters alone carry no significance apart from telling patients present status and hence are diminutive. This study aims to assess the hematological and serum biochemistry parameters and correlate them with the presenting symptoms and severity of disease which can help predict the need for intensive care unit (ICU) care, help in triage, assess the severity of the disease which will help clinicians decide their future course of action and further improve patients clinical outcome. METHODS: A total of 200 COVID-19 positive patients were included. Hematological and serum biochemistry parameters were recorded for the patients at the time of admission and categorized as mild, moderate, and severely ill based on clinical status and then admitted into various wards. RESULTS: Total leucocyte count (TLC) was significantly different and higher in severely ill patients (13,200 ± 6,999.2) compared to cases presented with mild and moderate symptoms (12,100 ± 6,488.41& 8,788.20 ± 4,954.32, p = 0.001). The mean difference of TLC, Neutrophil% (N%), Lymphocyte% (L%) and Monocyte (M%) was significantly different between mild and moderate symptoms cases (p = 0.030, p = 0.002, p = 0.004 & p = 0.003). Between groups comparison of moderate vs. severely ill cases showed a significant difference in TLC (p = 0.000), N% (p = 0.000), L% (0.000), and L/N ratio (p = 0.002). The serum ionic calcium (Ca), random blood sugar (RBS), C-reactive protein (CRP), fibrinogen, prothrombin (PT), International Normalized Ratio (INR), ferritin, and Lactate Dehydrogenase (LDH) level also differed significantly between mild, moderate and severely ill cases (p = 0.001, p=<0.001, p = 0.002, p=<00.1, p = 0006, p = 0.005, p=<0.001 and p=<0.001) respectively. Comparison of the mild vs. severely ill cases showed a significant difference in urea, fibrinogen, and procalcitonin (PCT) level (p = 0.005, p = 0.000 & p = 0.048) respectively. CONCLUSION: The preliminary findings of this study suggest hematological and serum biochemistry parameters could be used as a screening tool to identify patients requiring intensive care and thus allowing clinical stratification and triage at the time of presentation.

ABSTRACT

Introduction: Human immunodeficiency virus (HIV) may result in variable haematological manifestations. Thrombotic events are more common among HIV-infected persons than the general population, possibly due to the increased inflammatory/hypercoagulable state and presence of concurrent comorbidities. Aims and Objectives: (1) Screen for coagulation abnormalities in HIV-infected patients. (2) Detect certain prothrombotic factors such as deficiency of protein C and protein S and elevation of homocysteine as possible precursors of coagulation defects in HIV patients. (3) Correlation of coagulation abnormalities with CD4 counts. Methods: A pilot study of 1-year duration conducted in the Department of Pathology in collaboration with ART centre, KGMU Lucknow. All diagnosed HIV-seropositive patients (n = 30) who were not taking Vitamin K, antithrombotic and antiplatelet drugs including aspirin, oral contraceptives and not having known protein C/S deficiency were included in the present study as cases. Apart from this, 30 age- and sex-matched healthy individuals were also included in the present study. Assessment of the bleeding time, prothrombin time and activated partial thromboplastin time, complete blood count was done. Protein C and S were measured by calorimetric assay. Serum homocysteine was measured by the semi-automated method. CD4 count was done by flow cytometry. Results: The findings of the present study suggest a relationship between HIV, its complications and thrombosis. The HIV-seropositive patients have reduced levels of haemoglobin, CD4 counts, platelet counts, mean platelet volume, protein C and S activity as compared to the healthy individuals. Thrombophilic abnormality in the form of hyperhomocysteinaemia is more frequent in HIV-infected patients. All these parameters have a definite correlation with CD4 count.

ABSTRACT

INTRODUCTION: Non Alcoholic Fatty Liver Disease (NAFLD) is a metabolic disorder involving fat accumulation in the liver. The initial management for patients with NAFLD includes lifestyle modification and weight loss in overweight or obese patients. AIM: The present study was conducted to compare the efficacy of insulin sensitizers and statin in the patients of NAFLD. MATERIALS AND METHODS: The study included 98 patients diagnosed with NAFLD on USG (Ultrasonography) abdomen, divided into three Groups randomly and administered Metformin (Group I), Rosuvastatin (Group II) or Pioglitazone (Group III) along with dietary intervention and lifestyle modification. Their Body Mass Index (BMI), liver function tests, fasting lipid profile, USG scores for fatty liver were done and followed up at 4 weeks, 12 weeks and 24 week for change in above parameters. RESULTS: Out of the three Groups, Group II showed a maximum improvements in usg scores for NAFLD (p<0.001) and fasting lipid profile. Group II also showed maximum derangement of liver enzymes at 24 weeks though none of the subjects had more than three times elevation of liver enzymes. CONCLUSION: Rosuvastatin may be an effective therapy as add on treatment to dietary and lifestyle intervention in patients of NAFLD. As an add-on treatment Rosuvastatin was superior to Pioglitazone or Metformin and acute decompensation is unlikely with this drug. Metformin was not effective as add on therapy for NAFLD, rather rapid weight loss in short period of time resulted in worsening of hepatic steatosis.

ABSTRACT

OBJECTIVE: The study aims to evaluate the effect of zinc sulfate on markers of glycemic control, lipid profile and inflammation in type-2 diabetes with microalbuminuria patients. MATERIALS AND METHODS: Type-2 diabetes with microalbuminuria patients on oral hypoglycemic agents (OHA) and angiotensin converting enzyme (ACE) inhibitors were selected and divided into 2 groups: One group (n = 27) continued with OHA alone, second group (n = 27) was on OHA and in addition 50 mg elemental zinc as zinc sulphate supplementation for 12 weeks. Fasting, post-prandial blood glucose, glycosylated hemoglobin, lipid profiles, inflammatory marker hs-CRP and urine microalbumin were measured. RESULTS: There were no significant differences in biochemical status among groups at baseline. After receiving zinc, the mean fasting blood glucose (FBS), post-prandial blood glucose (PPBS) and glycosylated hemoglobin (HbA1c) were decreased significantly (P = 0.0001). Significant decrease was observed in TG (P = 0.002) and VLDL-cholesterol (P = 0.002), whereas there was no significant decrease in TC and LDL-cholesterol. The high-density lipoprotein (HDL) cholesterol was significantly (P = 0.0001) increased from baseline. Zinc supplementation had significant effects in decreasing serum hs-CRP from 10.51 ± 1.68 mg/L to 7.75 ± 1.56 mg/L (P = 0.0001) and microalbumin level from 146.87 ± 30.83 mg/day to 80.70 ± 33.99 mg/day (P = 0.0001). There were no significant changes in the levels of all these parameters in OHA group. CONCLUSION: Our results conclude that supplementation of zinc improved the effectiveness of OHA and may be beneficial in decreasing blood glucose, TG, urinary albumin excretion and inflammation in diabetic nephropathy patients and thus reducing the risk of complications.
