The Efficacy of Colchicine as an Adjunct Therapy in Non-hospitalized COVID-19 Patients: A Randomized Placebo-Controlled Trial.

The therapeutic potential of oral colchicine administration may help combat COVID-19 infection due to reduced disease severity and mortality risk. This randomized trial aimed to assess the effect of colchicine treatment on the inflammatory and hematologic markers as well as clinical features in non-hospitalized patients with mild-to-moderate COVID-19 disease. In the present placebo-controlled randomized trial, 80 non-hospitalized COVID-19 patients were enrolled and followed for 14 days. Subjects randomly received oral colchicine or placebo tablets once a day for two weeks. The fever and cough clinical signs, as well as Creactive protein (CRP) and lymphopenia, were evaluated through the follow-up. No significant between-group differences were observed in terms of the duration of clinical symptoms, CRP, and lymphopenia at 0, 7, and 14 days of intervention. Although the proportion of participants with fever, cough, positive CRP, and lymphopenia was higher reduced in the colchicine group than the placebo during treatment, no significant differences were found between groups. Due to no adverse effects detected in this trial, colchicine therapy was well-tolerated and safe. Our findings revealed that colchicine adjuvant therapy had no beneficial effect on clinical and para-clinical parameters in non-hospitalized COVID-19 patients during 14 days of intervention. The present trial does not support colchicine as a potential treatment against COVID-19 disease.

Relationship Between Hematologic Inflammatory Markers and Glycemic Control in Type 2 Diabetes Mellitus Patients in a Tertiary Hospital in Nigeria.

Hematologic inflammatory biomarkers derived from a full blood count (FBC) are elevated in Type 2 diabetes mellitus (DM). In low- and middle-income countries like Nigeria, a FBC is an affordable and easily available test, even in rural areas. Glycated hemoglobin (HbA1c), a measure of glycemic control, has been found to correlate with hematologic inflammatory markers. In Nigeria, where health care is expensive and patients essentially pay out of pocket, a more affordable and accessible alternative to HbA1c in determining glycemic control is needed. Therefore, this study aimed to determine the relationship between Hb A1c and hematologic inflammatory biomarkers, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and mean platelet volume (MPV), in predicting glycemic control. This was a six-month study of 109 patients with Type 2 DM in a tertiary hospital in Lagos. The patients' HbA1c and FBC were measured. NLR, PLR, and MPV were derived from the FBC values. We categorized the patients based on glycemic control. Spearman correlation analysis was used to determine the relationship between HbA1c and the inflammatory biomarkers. There was no significant difference in NLR, PLR, and MPV between optimal and suboptimal controlled diabetic patients. Spearman's correlation analysis showed no significant association between NLR, PLR, MPV, and HbA1c in the patients (NLR: r=0.027, P=0.680; PLR: r=-0.091, P=0.356; MPV: r=-0.032, P=0.744). The inflammatory markers studied had no significant relationship with HbA1c and might not help monitor glycemic control in Type 2 DM patients.

Effects of dietary supplementation with inactivated Lactobacillus plantarum on growth performance, haemato-biochemical parameters, liver fatty acids profile and intestinal microbiome of Nile tilapia.

This study investigated the effects of dietary supplementation with inactivated Lactobacillus plantarum for Nile tilapia (Oreochromis niloticus). Three treatments, in quintuplicate, were established: a control group, fish fed a diet without additives; LP group, fish fed a diet supplemented with live probiotic; and IP group, fish fed a diet supplemented with inactivated probiotic. Final weights (49.40 ± 3.15g) and weight gains (38.20 ± 3.23g) were increased in tilapia in the IP group. Feed conversion (1.32 ± 0.04) decreased significantly in the IP group. Haemato-biochemical parameters were significantly influenced by dietary supplementation. Erythrocyte count (262.74 ± 69.28 × 106 μL-1) was significantly low, while albumin (1.79 ± 1.12g dL-1) and cholesterol (254.14 ± 98.49mg dL-1) were high in the control group. Dietary supplementation modified the tilapia microbiome. Rhodobacter was abundant in fish intestines from the control and IP groups. Phreatobacter was abundant in the IP and LP groups, while Aurantimicrobium and Bosea were abundant in the LP group. Oleic acid (C18:1n9) was significantly increased in the LP (3.25 ± 0.49%) and IP (3.02 ± 0.30%) groups. Hexadecatrienoic acid (C16:3n4) was significantly increased (0.04 ± 0.01%) in the IP group, while Cis 11,14,17-eicosatrienoic acid (C20:3n3) (0.31 ± 0.03%) and adrenic acid (C22:4n6) (0.11 ± 0.02%) were significantly decreased in the LP group. Additionally, monounsaturated fatty acids (MUFA) were significantly increased (4.83 ± 0.35%) in the LP group compared to that in the control group. Collectively, these results indicate the potential of inactivated L. plantarum for use in commercial feed, leading to the conclusion that both inactivated and live L. plantarum can improve the Nile tilapia metabolism, altering haematological and biochemical markers.

Exploring the relationship between blood platelet and other components utilizing count regression: A cross-sectional study in Bangladesh.

Blood, vital for transporting nutrients and maintaining balance, comprises red blood cells, white blood cells, and platelets, each pivotal. Imbalances lead to issues-low red cells cause fatigue (anemia), high white cells hint at infection, low counts raise infection risks. Using trendy statistical approaches, investigating the complex link between platelet counts and numerous blood components. Our investigation, leveraging count regression approaches, revealed deep insights into the interaction between platelet counts and other important hematological markers. A cross-sectional study utilized data from 3120 individuals, including both male and female participants, who visited these hospitals between June 16, 2022 and December 17, 2022, to assess their blood samples through testing by using convenience non-parametric sampling framework. Platelet count was taken into account as a measure of outcome in this research. This specific study region was chosen for its easy accessibility, which helped the seamless execution of the data-gathering technique. Count regression, negative binomial regression, and quasi-Poisson regression techniques have been employed for examining relationship of the data sets. Three different count regression models were utilized to assess the proper association between the response and the relevant covariates and we found negative binomial count regression model (Akaike information criterion = 76.55, Bayesian information criterion = 76.59, and deviance = 3.14) was providing comparatively better performance than others. Based on the chosen model we found white blood cell, erythrocyte sedimentation rate, and eosinophils are significant but neutrophil, monocyte, and lymphocyte are not significant. We have also gone through proper model adequacy checking for our selected model and we found enough evidence to justify our model. From the result, we found insightful remarks into the mechanisms involved in platelet production and regulation, which can aid in developing increased effective treatments and interventions to maintain optimal platelet levels and prevent health problems related to abnormal platelet counts.

Neutrophil-to-Lymphocyte Ratio and Cytokine Profiling as Predictors of Disease Severity and Survival in Unvaccinated COVID-19 Patients.

During the COVID-19 pandemic, identifying reliable biomarkers for predicting disease severity and patient outcomes in unvaccinated individuals is essential. This study evaluates the efficacy of key hematological markers, including leukocyte and neutrophil counts, Neutrophil-to-Lymphocyte Ratio (NLR), and cytokine profiles (IL-6, INF-γ, TNF-α, IL-17A, CCL2, and CXCL10) for predicting the necessity for mechanical ventilation and assessing survival probabilities. We conducted an in-depth analysis on a cohort of COVID-19 patients, emphasizing the relationship between NLR, cytokine profiles, and clinical outcomes, utilizing routine leukocyte counting and cytokine quantification by flow cytometry. Elevated leukocyte and neutrophil counts, increased NLR, and significant cytokine elevations such as IL-6 and IL-10 were strongly associated with the need for mechanical ventilation, reflecting a pronounced systemic inflammatory response indicative of severe disease outcomes. Integrating hematological markers, particularly NLR and cytokine profiles, is crucial in predicting mechanical ventilation needs and survival in non-vaccinated COVID-19 patients. Our findings provide critical insights into the pathophysiology of COVID-19, supporting the development of more targeted clinical interventions and potentially informing future strategies for managing infectious disease outbreaks.

Machine learning-derived prognostic signature for progression-free survival in non-metastatic nasopharyngeal carcinoma.

Early detection of high-risk nasopharyngeal carcinoma (NPC) recurrence is essential. We created a machine learning-derived prognostic signature (MLDPS) by combining three machine learning (ML) models to predict progression-free survival (PFS) in patients with non-metastatic NPC. A cohort of 653 patients with non-metastatic NPC was divided into a training (n = 457) and validation (n = 196) dataset (7:3 ratio). The study included clinicopathological characteristics, hematologic markers, and MRI findings in three machine learning models-random forest (RF), extreme gradient boosting (XGBoost), and least absolute shrinkage and selection operator (LASSO)-to predict progression-free survival (PFS). A Venn diagram identified the overlapping signatures from the three ML algorithms. Cox proportional hazard analysis determined the MLDPS for PFS. The RF, XGBoost, and LASSO algorithms identified six consensus factors from the 33 signatures. Cox proportional hazards analysis showed that the MLDPS includes age, lymphocyte count, number of positive lymph nodes, and regional lymph node density. Additionally, MLDPS effectively stratified prognosis, with low-risk individuals showing better PFS than high-risk individuals (p < 0.001). MLDPS, based on clinicopathological characteristics, hematologic markers, and MRI findings, is crucial for guiding clinical management and personalizing treatments for patients with non-metastatic NPC.

Vitamin D levels in Coronavirus-infected Individuals and its Correlation with Certain Hematological Markers

The world and nearly all our health care system were confronted by a significant threat which was declared by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Determining the SARS-CoV-2 or COVID-19’s prognostic and modifiable measures surely would largely contribute to outcome improving despite the deficiency of causative therapy that affected nearly 200 million people, 3.5 million fatal incidences, and it is still airborne. The research in hand examined probable relations between the levels of vitamin D (VitD) and immunological markers. Hence, a sample of 200 lecturers and students from Cihan University-Erbil were assigned, (150 males, 50 females) whom ages were between 22 to 25, with some respondents were treated from a previous COVID-19 infection. The results showed that 98 (or 49%) of the 200 samples had Covid-19 infection. Males 60/98 had a greater prevalence rate (61%), whilst females 38/98 had a lower rate (39%). According to immunological ELISA results, every patient had positive IgG antibodies and negative IgM antibodies. Compared to the healthy group, the serum levels of IgE rose considerably in Covid-19 patients. However, when compared to the healthy group, the serum level of vitamin D3 in the Covid-19 recovered patients showed a considerable reduction. The mean results for hematological parameters indicated a non-significant increase in the number of red blood cells relative to the healthy group, but a significant increase in the WBC count, Hb concentration, and platelets. Thus, the result indicates the necessity for interventional studies on vitamin D supplementation in SARS-CoV-2 infected persons by showing a correlation between vitamin D deficit and WBC count during COVID-19 recovery.

A comprehensive review of synbiotics: an emerging paradigm in health promotion and disease management.

Synbiotics are complex preparations of prebiotics that can be selectively utilized by live microorganisms to improve host health. Synbiotics are divided into complementary synbiotics, which consist of probiotics and prebiotics with independent functions, and synergistic synbiotics, which consist of prebiotics that are selectively used by gut microorganisms. Complementary synbiotics used in human clinical trials include Lactobacillus spp. and Bifidobacterium spp. as probiotics, and fructooligosaccharides, galactooligosaccharides, and inulin as prebiotics. Over the past five years, synbiotics have been most commonly used in patients with metabolic disorders, including obesity, and immune and gastrointestinal disorders. Several studies have observed alterations in the microbial community; however, these changes did not lead to significant improvements in disease outcomes or biochemical and hematological markers. The same synbiotics have been applied to individuals with different gut environments. As a result, even with the same synbiotics, there are non-responders who do not respond to the applied synbiotics due to the different intestinal environment for each individual. Therefore, to obtain meaningful results, applying different synbiotics depending on the individual is necessary. Synergistic synbiotics are one solution to circumvent this problem, as they combine elements that can effectively improve health, even in non-responders. This review aims to explain the concept of synbiotics, highlight recent human clinical trials, and explore the current state of research on synergistic synbiotics.

Changes in the leukocyte component and the role of hematological indices in cardiovascular diseases: focus on surgical myocardial revascularization (literature review)

The high prevalence of cardiovascular diseases inevitably entails an increase in the number of annual surgical myocardial revascularization procedures. In this regard, the increasing risk of postoperative complications is obvious. The aim of this work was to analyze the available literature on the study of the systemic inflammatory response (SIR) in cardiovascular diseases with an emphasis on coronary artery bypass grafting (CABG). The study of the mechanisms of SIR after cardiac surgery allowed attempts to suppress the activity of the cytokinin storm. The main significance of leukocytes in the initiation of SIR served as the reason for studying the prognostic value of the leukocyte level, both in the postoperative and preoperative periods. The article reflects data on the role of hematological markers and indices. In addition, the results of studies on the significance of a normal high level of leukocytes in the preoperative period are presented, since a negative prognosis was noted in such a group of people who underwent CABG. While remaining a widely accessible and inexpensive method, the assessment of the leukocyte formula, as well as the calculated hematological indices, acquire predictive value for postoperative complications and outcomes.

Alterations in hematologic, coagulation, and inflammatory markers based on fever status in hospitalized COVID-19 patients: A retrospective study.

Laboratory markers like lymphopenia, thrombocytopenia, elevated D-dimer, and C-reactive protein (CRP) predict worse outcomes in coronavirus disease 2019 (COVID-19). However, a comprehensive analysis of hematologic and coagulation parameter alterations based on fever status is lacking. This retrospective study analyzed 300 COVID-19 patients hospitalized from March to December 2020. Demographic, clinical, and laboratory data were extracted from electronic medical records. Patients were stratified into fever (n = 200) and no fever (n = 100) groups. Hematologic, coagulation, and inflammatory markers were compared between groups using appropriate statistical tests. Multivariate regression identified independent predictors of fever. Fever was associated with leukocytosis, neutrophilia, lymphopenia, thrombocytopenia, elevated CRP, D-dimer, procalcitonin, interleukin-6, neutrophil to lymphocyte ratio (NLR), and ferritin compared to no fever (all P < 0.05). D-dimer (r = 0.42), CRP (r = 0.52), NLR (r = 0.48), and interleukin-6 (r = 0.46) demonstrated the strongest correlation with fever (P < 0.001). High D-dimer >1000 ng/mL (adjusted odds ratio 2.7), CRP >100 mg/L (3.1), lymphopenia <1.0 × 109/L (2.8), NLR >4 (2.9), and thrombocytopenia <150 × 109/L (2.7) were significant independent predictors of fever status (P < 0.005). These parameters had moderate sensitivity (40-60%) and high specificity (74-88%) for discriminating febrile patients with AUC of 0.85. Marked alterations in hematologic, coagulation, and inflammatory markers occur in COVID-19 based on fever. Routine laboratory parameters can facilitate diagnosis and risk stratification.

Helicobacter pylori infection increases the risk of dyslipidemia in Chinese diabetic Population: a retrospective cross-sectional study

BackgroundIn contemporary times, increased prevalence of Helicobacter pylori (H. pylori) infection and elevated dyslipidemia levels present substantial public health challenges. However, the relationship between H. pylori and dyslipidemia remains inconclusive. No studies have yet conducted a population-based classification to investigate the impact of H. pylori infection on dyslipidemia in individuals with diabetes.MethodsA retrospective cohort study was carried out on a total of 60,535 individuals who underwent health check-ups at the Health Examination Center in Taizhou Hospital from 2017 to 2022. Physical measurements, hematological markers and detection of H. pylori were gathered from all patients. The study population was further stratified into diabetic and non-diabetic groups for analysis.ResultsH. pylori infection was found to be an autonomous risk factor for dyslipidemia based on the results of multivariate logistic regression analysis (OR = 1.13, 95% CI: 1.03–1.24). However, no notable effect on dyslipidemia in the non-diabetic group was observed. Furthermore, at the follow-up, the group with persistent negative showed a significantly lower incidence ratio of dyslipidemia compared to the group with persistent infection (P = 0.006). The persistent negative group exhibited a significantly higher rate of improvement in dyslipidemia compared to the new infection group (P = 0.038).ConclusionsIn the diabetic population, the presence of H. pylori infection heightens the propensity for developing dyslipidemia. Therefore, the implementation of efficient eradication strategies for H. pylori infection could potentially lead to a decrease in the occurrence of dyslipidemia among individuals with diabetes.

The Association of Hematological Markers with Occurrence of Thrombotic and Bleeding Events following Left Atrial Appendage Occlusion.

Patients undergoing left atrial appendage occlusion (LAAO) are at increased risk for bleeding or thromboembolic events. Concurrently, biomarkers are of growing importance in risk stratification for atrial fibrillation patients. We aimed to evaluate the association of hematological markers and clinical characteristics with the occurrence of thromboembolic and bleeding events following LAAO. Seven implanting centers retrospectively gathered data on hematological markers (i.e., platelet count [PC], mean platelet volume [MPV], and fibrinogen) prior to LAAO. Prespecified thromboembolic and major bleeding outcomes were collected and the association with pre-procedural hematological markers and clinical characteristics was evaluated using Cox regression analysis. In total, 1,315 patients were included (74 ± 9 years, 36% female, CHA2DS2-VASc 4.3 ± 1.5, HAS-BLED 3.3 ± 1.1). Over a total follow-up duration of 2,682 patient years, 77 thromboembolic events and 107 major bleeding events occurred after LAAO. Baseline PC was the only biomarker showing a signal for a relation to thromboembolic events (HR 1.18, 95% CI: 1.00-1.39) per 50*109 increment, p = 0.056). Thrombotic event rates, including device-related thrombus, increased within higher PC quartiles. Thromboembolism was associated with age (HR 1.05, 95% CI: 1.00-1.10, per year increase) and prior thromboembolism (HR 2.08, 95% CI: 1.07-4.03), but with none of the biomarkers in multivariate analysis. No association of any of the hematological markers with major bleeding was observed. Major bleeding following LAAO was associated with prior major bleeding (HR 5.27, 95% CI: 2.71-10.22), renal disease (HR 1.93, 95% CI: 1.17-3.18), and discharge on dual antiplatelet therapy (DAPT) (HR 1.71, 95% CI: 1.05-2.77). Most thrombotic events occurred in the highest PC quartile, but no association of any of the hematological markers with thromboembolism or major bleeding was observed in our analysis. In multivariate analysis, older age and prior thromboembolism were associated with thromboembolism. Prior major bleeding, renal disease and discharge on DAPT were multivariate predictors of major bleeding after LAAO.

Pediatric COVID-19 diagnosis: The utility of hematological and inflammatory indices

This study aims to systematically assess the diagnostic utility of specific hematological parameters and indices in pediatric patients for the early and accurate diagnosis of COVID-19, thereby contributing to enhanced clinical management and diagnosis of children. The study evaluated the diagnostic potential of hematological and inflammatory markers in 90 pediatric patients, including 49 with COVID-19 and 41 without. It focused on complete blood counts, systemic immune-inflammatory index (SII, calculated as platelet count multiplied by neutrophil count divided by lymphocyte count), platelet to mean platelet volume ratio (PLT/MPV), neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, C-reactive protein, and procalcitonin, comparing these markers between patients with and without COVID-19. COVID-19 positive patients exhibited higher hemoglobin levels and immature granulocyte percentages, along with lower total leukocyte, neutrophil, platelet counts, and procalcitonin levels (p-values: 0.02, 0.006, 0.01, 0.002, 0.007, and 0.01, respectively). The SII and PLT/MPV ratio were significantly lower in the COVID-19 positive group (p=0.01 and p=0.006, respectively), suggesting their potential diagnostic relevance. Receiver Operating Characteristic (ROC) analysis revealed that procalcitonin, PLT/MPV, and SII had comparable diagnostic utility, with area under the curve (AUC) values indicating moderate diagnostic accuracy (procalcitonin AUC: 0.65, p=0.013; PLT/MPV AUC: 0.67, p=0.004; SII AUC: 0.65, p=0.01). Our research highlights the PLT/MPV ratio and SII as breakthrough markers for early detection of COVID-19 in children, providing a significant advance in pediatric diagnostics and enhancing our ability to meet the challenges of the pandemic.

Hematological, Biochemical, and Inflammatory Markers in Patients Suffering from SARS-CoV-2 in Kassala, Sudan: A Cross-Sectional Hospital-Based Study

Introduction: Sudan faces the impact of SARS-CoV-2, emphasizing the urgency of timely detection and effective management. This study, conducted in Kassala, Sudan, aimed to evaluate key hematological, biochemical, and inflammatory markers in confirmed and suspected COVID-19 patients. Methodology: A cross-sectional hospital investigation was carried out in Kassala State, eastern Sudan, spanning from September 2020 to January 2021. Clinical and sociodemographic data were collected from individuals suspected of having COVID-19 using a structured questionnaire. Nasopharyngeal swab was targeted for the detection of SARS-CoV-2 while a blood sample was processed for haematological and biochemical parameters. Results: The study included 371 participants, revealing a prevalence of COVID-19 PCR positive of 61.7% (229/371). In particular, most were male (65%), with a mean age of 42.9±19.9 years. A substantial case fatality rate of 15.7% (36/229) was observed, predominantly among people 60 years and older (P &lt; 0.001). RT-PCR-confirmed patients exhibited significant associations with elevated erythrocyte sedimentation rate, C-reactive protein levels, prolonged Prothrombin time, extended partial thrombin time, leucocytosis, neutrophilia, lymphopenia and hypocalcemia (P &lt; 0.000). Conclusion: This study illuminates the impact of COVID-19 on crucial hematological, renal electrolyte, inflammatory, and coagulation markers. These findings have the potential to enhance patient outcomes and reduce mortality rates by guiding informed actions and shaping public health policies.

Safety and efficacy assessment of an mRNA rabies vaccine in dogs, rodents, and cynomolgus macaques

Rabies is a lethal disease caused by the rabies virus (RABV), which causes acute neurological infections in mammals, including human beings. We previously reported that an mRNA vaccine (LVRNA001) encoding the rabies virus’s glycoprotein induced strong protective immune responses to rabies in mice and dogs. Here, we further evaluate the safety of LVRNA001. First, we performed a confirmative efficacy study in dogs, which showed that LVRNA001 fully protected the animals from the virus, both pre- and post-infection. Moreover, using pre- and post-exposure prophylaxis murine models, we showed that LVRNA001, built from the CTN-1 strain, was able to protect against various representative RABV strains from the China I–VII clades. To evaluate the safety of the vaccine, chronic and reproductive toxicity studies were performed with cynomolgus macaques and rats, respectively. In a repeated-dose chronic toxicity study, vaccinated monkeys displayed no significant alterations in body weight, temperature, or hematological and biochemical markers. Lymphocyte subset measurement and histopathological examination showed that no toxicity was associated with the vaccine. The immunogenicity study in cynomolgus macaques demonstrated that LVRNA001 promoted the generation of neutralizing antibodies and Th1-biased immune response. Evaluation of reproductive toxicity in rats revealed that administration of LVRNA001 had no significant effects on fertility, maternal performance, reproductive processes, and postnatal outcomes. In conclusion, LVRNA001 can provide efficient protection against rabies virus infection in dogs and mice, and toxicity studies showed no significant vaccine-related adverse effects, suggesting that LVRNA001 is a promising and safe vaccine candidate for rabies prophylaxis and therapy.

Exploring the association between haematological markers of iron and general movements in 4-month-old infants exposed to anaemia in-utero

BackgroundIron is a vital micronutrient for brain development, influencing myelination, neurotransmitter balance, and the maturation of specific brain cells. Hence iron insufficiency in the foetal, neonatal and infancy period has the potential to influence the neuromotor development. AimsWe aimed to describe haematological markers of iron at 4 months of age in infants exposed to prenatal anaemia and explore the association with their quality of general movements. Study designCross sectional study nested within the RAPIDIRON-KIDS trial. SubjectsAll infants whose mothers were part of RAPIDIRON-KIDS trial, were eligible to participate in this study when the infants were 4 months old. Children suffering from fever or acute illness on the day of assessment, or with a history of either surgery, or admission to hospital in the first month were excluded. Outcome measuresHaematological markers of iron (Haemoglobin and Ferritin level) and quality of general movements in infants at 4 months of age. Results120 infants were assessed with mean birth weight of 2685.5 g (±384.5) and median gestational age of 39 weeks [Q1, Q3:38,40]. There was no significant association between haemoglobin or ferritin levels with fidgety movements (p = 0.18 and p = 0.27, respectively). The combined effect of haemoglobin and ferritin estimates also did not show any significant association with the study groups (p = 0.21). ConclusionA majority of infants still had low iron indices at 4 months of age and this was not associated with the quality of general movements. A prospective longitudinal study needs to be considered in infants exposed to prenatal anaemia rather than assessing the outcomes at a single time point.

PERIPHERAL BLOOD COUNT RECOVERY TIME COURSE DURING INDUCTION TREATMENT FOR ACUTE LYMPHOBLASTIC LEUKEMIA IN CHILDREN

Background: In recent years, the survival rate of pediatric ALL patients has increased to almost 90%, particularly for individuals with favorable prognoses. This success is mostly attributable to the use of risk-adapted medication, enhanced supportive care, and adjustments to therapy based on each patient's unique pharmacodynamics and pharmacogenomics. This research investigates ALL patients' response to induction chemotherapy, focusing on changes in peripheral blood cell counts and hematological markers, to predict therapeutic outcomes and provide a practical prognostic parameter. Methods: This study involved 100 under 15-year-old patients with newly diagnosed ALL treated in pediatric leukemia units at Kuwait Hospital, Sana'a. Blood markers were collected and analyzed using Epi Info statistical program version 6. The study followed the French, American, and British classifications of pediatric leukemia. Participants were informed of the study's goals and advantages, and their participation was optional. Results: The majority of patients were aged 5-9 years, with a mean age of 6.9 years. Hemoglobin levels were measured before and after treatment, with the mean level being 8.8 mg/dL before and 10.8 mg/dL after treatment. Severe anemia was reported in 10% of patients before treatment and decreased to 2% after treatment. PCV levels were also measured before and after treatment, with the mean PCV level being below normal in 66% of patients before induction chemotherapy but improving to 20% after treatment. The mean RBC count before treatment was 2.9 cells × 106/μl, but improved to 3.8 cells × 106/μl after induction chemotherapy. The study found that over 50% of patients had iron deficiency anemia before and after induction chemotherapy, with a mean neutrophil percentage of 18.2%, lymphocyte percentage of 73.7%, monocyte percentage of 3.8%, and eosinophil percentage of 0.85%. Conclusions: The study reveals that blood cell parameters replenish at different rates during induction chemotherapy, resulting in rapid platelet and slow neutrophil recovery. Changes in blood markers during induction may be prognostic.

Study on the Toxic Effects of Deltamethrin on Hematological Parameters of a Fresh Water Fish, Common Carp (Cyprinus carpio L.)

Fish health is adversely affected by pesticide contamination, which is a significant cause of pollution in freshwater ecosystems. One helpful technique for assessing the general health of different fish species is the analysis of blood parameters. Present study investigated the detrimental effects of deltamethrin on different hematological parameters of a fresh water fish, common carp (Cyprinus carpio). An experiment with a 28-day exposure to 1/20th and 1/10th of the 96-hour LC50 value (0.114µl/L) was conducted in order to investigate the effects of sub-lethal concentrations. On the 7th, 14th, 21st, and 28th day of exposure, several hematological parameters like Total Erythrocyte Count (TEC), Total Leukocyte Count (TLC), Hemoglobin (Hb), Hematocrit/Packed Cell Volume (Hct/PCV), Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH) and Mean Corpuscular Hemoglobin Concentration (MCHC) were analyzed in comparison to control. After the exposure of different concentrations of deltamethrin significant decline (P*&lt;0.05 and P**&lt;0.01) in Hb, TEC, PCV and MCHC was noted as compared to control. On the contrary TLC, MCV and MCH showed increasing trend after the treatment of pesticide. This study showed that deltamethrin considerably altered the hematological markers of fish, even at sub-lethal concentrations.
