Basic biochemical and hematological parameters in COVID-19 deceased: Analysis of potential mortality predictors

Introduction: As a result of research conducted globally, experts continue to extensively study the long-term consequences that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can have on patients, as well as the factors contributing to severe outcomes. The aim of this study was to investigate the values of basic biochemical and hematological parameters in patients with fatal outcomes of SARS-CoV-2 infection, as well as to determine the combination of hematological and biochemical parameters that contribute to the progression of SARS-CoV-2 infection. The examined parameters were correlated with the age and gender distribution of patients with fatal outcomes from the SARS-CoV-2 infection. Methods: The study represents a retrospective study of patients hospitalized at the Cantonal Hospital Zenica from February to April 2021, focusing on the biochemical and hematological parameters of subjects with confirmed presence of the SARS-CoV-2 virus using the reverse transcription-polymerase chain reaction methods who were hospitalized at the Cantonal Hospital Zenica. Results: Of the 250 deceased subjects in the sample, females comprised the relative majority at 53.6%. Among the examined parameters, hemoglobin, mean corpuscular hemoglobin (MCH), and MCH were significantly lower in females compared to males, while males had significantly higher values of urea, creatinine, and troponin. The average age of the patients was 74 years, and with aging, the values of erythrocytes, hemoglobin, and troponin increased. Troponin showed a statistically significant positive correlation with age, as well as with urea and creatinine. Conclusion: We can conclude that hemoglobin, urea, creatinine, and troponin are parameters that can be considered to contribute to the progression of SARS-CoV-2 infection. These parameters can be useful for assessing disease severity and prognosis in patients infected with the SARS-CoV-2 virus.

Evaluation of Some Hematological Parameters in Patients with Diabetes Mellitus Attending Abia State University Teaching Hospital Aba Based on Socio-Demographic Characteristics

The evaluation of lipid profile and some hematological parameters in diabetic patients attending Abia State Teaching Hospital Aba, was carried out. Venous blood samples were collected from 150 participants who gave consent. This comprises 100 diabetic patients as test and 50 healthy subjects as control. The plasma glucose and hemoglobin levels were determined using spectrophotometric methods. Data from this study were analyzed using statistical package for the social sciences (SPSS). Result shows that, platelet (395.44±72.11x109/l), prothrombin time (13.63±0.95secs) levels were higher in study population compared with control (176.18±25.26x109/l, 11.85±0.63secs, respectively) (p<0.05 in each case). The hemoglobin (124.83±15.01g/l) was lower in diabetic patients compared with control (131.66±10.45g/l) (p<0.05). From the findings, management of conditions related to cardiovascular disease, artherosclerotic disease, anemia and stress in diabetics may benefit patients if some hematological parameters are included as part of their routine laboratory investigations.

Assessment of the hematological profiles among COVID-19 patients during the first and second waves in Ethiopia: A multicenter retrospective cohort study

Background: The coronavirus disease 2019 is highly infectious and patients with coronavirus diseases demonstrated a series of clinical symptoms caused by severe acute respiratory syndrome coronavirus-2. Without a break of the wave’s hematological profile of the patients is still ambiguous and differs from wave to wave. Objective: This study aimed to assess the hematological profile among coronavirus disease 2019 patients during the first and the second waves in Ethiopia. Methods: A multi-centered facility-based retrospective cohort study design was conducted at six coronavirus disease 2019 treatment centers. A total of 538 study participants were enrolled in the selected coronavirus disease 2019 treatment centers during the first and second waves of the pandemic. The demographic characteristics, underlying diseases, symptoms, and hematological parameters of patients were recorded. Data were entered into Epi-Data Manager 4.6 and analyzed using STATA 14.2. An independent sample t-test was used to assess the mean differences in hematological parameters across waves. Associations between categorical variables across waves were also determined using Chi-square and Fisher exact tests. Results: Among the total study participants, 240 (44.6%) and 298 (55.4%) patients were taken from wave-1 and wave-2, respectively. The average age of the study participants was 56.44 ± 16.25 years. The most frequent comorbidities in this study were hypertension, diabetes mellitus, ischemic heart disease, and asthma. The most presenting symptoms of COVID-19 infection across the two waves were presented. In the first wave, dry cough 166 (69.2%), fatigue 153 (63.75%), shortness of breath 148 (61.67%), and fever accounted 116 (48.33%), while during the second wave, dry cough 242 (81.2%), fatigue 244 (81.88%) shortness of breath 204 (68.47%) and fever account 180 (60.40%). White blood cells (WBC), neutrophils, and lymphocytes had shown increment during the first wave. Platelet count and platelet distribution width ( p < 0.001) had significant mean differences across the two waves, while the other had no significant mean difference. Conclusion: In the present study, dry cough, fatigue, shortness of breath, and fever were found to be the most presenting symptoms of COVID-19 infection across the two waves. Only the platelet count and platelet distribution width had significant mean differences across the two waves, while the other had no significant mean difference across waves.

Retrospective study of a novel hematological parameter for predicting the survival of patients with nasopharyngeal carcinoma.

This study aims to explore the prognostic values of routine pre-treatment hematological parameters in patients with nasopharyngeal carcinoma (NPC). The hematological parameters and clinical data of patients with NPC were collected from January 2012 to December 2013 at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. The survival statistics were obtained by regularly following-up the patients. The cut-off values for the hematological parameters were calculated using X-tile software. SPSS version 24.0 was used for the statistical analysis. The relationship between the hematological parameters and the prognosis of patients with NPC was analyzed using the Kaplan-Meier method and Cox multivariate regression. The discriminating abilities of the factors, which predict the prognosis, were evaluated by utilizing the receiver operating characteristic (ROC) area under the curve (AUC). This study included 179 patients with NPC. Multivariate analysis shows that pretreatment platelet-to-lymphocyte ratio (PLR; hazard ratio; HR = 0.44, 95% CI [0.21-0.91], p=0.029), serum albumin (ALB; HR = 2.49, 95% CI [1.17-5.30], p=0.018), and globulin (GLO; HR = 0.44, 95% CI [0.21-0.90], p=0.024) are independent predictors for 5-year overall survival (OS) in patients with NPC. In addition, pre-treatment PLR (HR = 0.47, 95% CI [0.25-0.90], p=0.022) and pre-treatment GLO (HR = 0.37, 95% CI [0.19-0.72], p=0.001) are associated with 5-year progression-free survival (PFS) in patients with NPC. Based on the results of the multivariate analysis, we proposed a new biomarker GLO-PLR, which is observably correlated with the T stage, N stage and clinical stage in patients with NPC. The OS resolving ability of the GLO-PLR evaluated by AUC is 0.714, which is better than those of GLO and PLR. The PFS resolving ability of the GLO-PLR evaluated by AUC was 0.696, which is also better than those of GLO and PLR. Pre-treatment PLR, ALB, and GLO are independent predictors of 5-year OS in patients with NPC, where PLR and GLO are also independent predictors of 5-year FPS. Compared with other hematological parameters, the proposed GLO-PLR is an inexpensive, effective, objective, and easy-to-measure marker for predicting the prognosis of NPC.

Interaction between coagulation and inflammatory system in liver disease: re-focus on hematological markers.

Aim: This study uses blood routine, coagulation and biochemical indicators to explore the relationship between the hematological parameters of patients with various types of liver diseases.Methods: The Kruskal-Wallis, Chi-squared and Fisher exact tests were used to compare the hematological parameters and clinical characteristics of three groups of patients with different degrees of liver disease. Spearman correlation analysis is used to analyze the correlation between two continuous variables. The logistic regression model evaluated the odds ratio between variables and disease changes. Receiver operating characteristic curve analysis was used to understand the predictive value of each index in relation to the progress of liver disease.Results: There are differences in inflammation and coagulation profiles among different types of liver diseases and there is a correlation between them. In addition to the traditional marker α-fetoprotein, the inflammatory marker c-reactive protein and the coagulation marker D-dimer also have good diagnostic value for liver injury.Conclusion: The coagulation and inflammation systems interact, are connected and play essential roles in the liver.

Clinical Assessment of Cytokine Profiles and Haematological Parameters in Patients with Systemic Lupus Erythematosus: A Cross-Sectional Study from Saudi Arabia.

Systemic lupus erythematosus (SLE)-related hematological disorders have different pathogenic mechanisms involving immune dysregulation as well as microangiopathy. The current study aimed to assess the relationship between pro- and anti-inflammatory cytokines and SLE-related hematological abnormalities for Saudi Patients. The current cross-sectional study including 140 participants was performed at the Prince Mohammad bin Abdulaziz Hospital (PMAH), Riyadh, Saudi Arabia. Two blood samples were collected from each of the study participants for evaluation of the haematological indices including complete blood count (CBC), erythrocyte sedimentation rate (ESR), and cytokine profile (i.e., tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10)). Statistical analyses were performed using the Statistical Package of Social Sciences (SPSS) software, v25. Haematological abnormalities were documented in 63% of SLE patients, and anaemia was the highest at 52%. Haemoglobin levels were found to be significantly lower among SLE patients compared to the controls (p < 0.001). In the cytokine profiles, the levels of TNF-α (p < 0.001), IL-6 (p < 0.001), and IL-10 (p = 0.009) were significantly higher among SLE patients compared to the controls. A positive correlation was also identified between TNF-α, platelet count, red cell distribution width (RDW), and ESR. Haematological abnormalities were found to be the most common among SLE patients. Further, the correlation between cytokine profile and haematological indices indicates the influence of cytokines in the development of haematological abnormalities. Understanding hematological abnormalities and cytokines' role in the pathogenesis of these abnormalities may aid in the early diagnosis and development of more specific SLE disease therapies.

Increased Expression of NOTCH-1 and T Helper Cell Transcription Factors in Patients with Acquired Aplastic Anemia.

Acquired aplastic anemia is an autoimmune disease in which auto-aggressive T cells destroy hematopoietic progenitors. T-cell differentiation is controlled by transcription factors that interact with NOTCH-1, which influences the respective T-cell lineages. Notch signaling also regulates the BM microenvironment. The present study aimed to assess the gene expressions of NOTCH-1 and T helper cell transcription factors in the acquired aplastic anemia patients. Using quantitative real-time PCR, we studied the mRNA expression level for NOTCH-1, its ligands (DLL-1 and JAG-1), and T helper cell transcription factors (T-BET, GATA-3, and ROR-γt) in both PB and BM of aAA patients and healthy controls. Further, patients of aplastic anemia were stratified by their disease severity as per the standard criteria. The mRNA expression level of NOTCH-1, T-BET, GATA-3, and ROR-γT genes increased in aAA patients compared to healthy controls. There was no significant difference in the mRNA expression of Notch ligands between patients and controls. The mRNA expression level of the above-mentioned genes was found to be higher in SAA and VSAA than NSAA patients. In addition, NOTCH-1 and T helper cell-specific transcription factors enhanced in aAA. We also observed a significant correlation between the genes and hematological parameters in patients. The interaction between NOTCH-1, T-BET, GATA-3, and ROR-γT might lead to the activation, proliferation, and polarization of T helper cells and subsequent BM destruction. The mRNA expression levels of genes varied with disease severity, which may contribute to pathogenesis of aAA.

Comparison of iron and some hematological parameters between patients with Giardia lamblia and healthy control

Giardia lamblia, a protozoan parasite featuring flagella .and binucleation, is capable of infecting a diverse range of mammalian hosts. The incidence of human giardiasis, a veritable cosmopolitan pathogen, is most pronounced in developing nations.&#x0D; The objective of the present study was to evaluate the impact of an infection caused by the Giardia lamblia parasite on iron levels and various hematological parameters in patients.&#x0D; the study conducted between August 2022 and February 2023, blood samples were collected from people who were infected and non-infected with Giardia lamblia to evaluate the element iron and some blood indicators and the extent to which they were affected by infection. 60 blood samples (36 males and 24 females) were taken from people infected with Giardia, and 30 blood samples (15 males and 15 females) were taken from healthy people (controls). The infection was diagnosed by a direct smear and cultured in the laboratory. The control group underwent both clinical and laboratory examinations to confirm the absence of any disease.&#x0D; The findings of the present investigation exhibit a noteworthy reduction in the average levels of serum iron (SI)., mean number of red blood cells (RBC), hemoglobin (Hb), and percentage of the packed cell volume (PCV) in people with the disease compared to healthy subjects, while a significant increase in the mean of the total number of white blood cells (WBC) was recorded in patients compared to healthy subjects.&#x0D; Individuals with Giardia labmlia may exhibit notable changes in several hematological factors. Routine assessment of hematological factors is necessary for timely detection and effective treatment of giardiasis.

Hematological markers of periprosthetic joint infection after revision total hip arthroplasty

Analysis of clinical and laboratory tests is essential for monitoring the course of infectious complications after total hip arthroplasty (THA).The objective was to assess the reliability of differences in hematological parameters in patients with periprosthetic joint infection (PJI) for monitoring the infectious process.Material and methods Patients with acute (lasting 21.8 days on average) and chronic (lasting for 26.3 months on average) PJI were screened for hematological parameters on admission and during treatment in order to control the course of the purulent-inflammatory process.Results Preoperative parameters demonstrated mild anemia in patients with acute PJI, and the hemoglobin concentration was normal in patients with chronic PJI. Patients of both groups showed normal total leukocyte count. ESR and C-reactive protein levels were many times higher than the threshold values. The C-reactive protein level was more than 2 times higher in patients with acute PJI than that in patients with a chronic infection. The ratio of ESR / C-reactive protein was normally greater than 5 units, from 3 to 4.5 in chronic PJI and from 1.5 to 2.3 in acute PJI. Discussion Examination of pre- and postoperative clinically significant parameters is practical for identification of the criteria to assess the risk of chronic PJI.Conclusion Patients with acute PJI need no additional clinical and laboratory examination, integral laboratory parameters can be employed for accurate assessment of the extent of inflammation in a purulent wound.

Comparative analysis of glycated haemoglobin, fasting blood glucose and haematological parameters in Type-2 diabetes patients

ObjectiveDiabetes remains a major health problem, and Glycated hemoglobin (HBA1c) and fasting blood glucose (FBG) levels play important roles in its management. Also, chronic hyperglycemia coupled with high HBA1c levels impact inflammation and may alter haematological parameters in diabetes. Hence, the need to assess and correlate HBA1c and FBG levels with selected haematological parameters in patients with type-2 diabetes mellitus as the main objective of this study. The study was cross-sectional involving 384 participants. Five milliliters of blood was collected from each participant and analyzed for HBA1c, FBG levels and full blood count which were correlated statistically.ResultsFrom the data obtained and analyzed, there were statistically significant correlations between HBA1c and neutrophil count (p < 0.013), plateletcrit (p < 0.036), mean platelet volume (p < 0.019) and platelet distribution width (p < 0.002). There were also significant differences in FBG (p < 0.014), neutrophil count (p < 0.029), red cell distribution width (p < 0.046), mean platelet volume (p < 0.032) and platelet distribution width (p < 0.013) between diabetes patients with HBA1c less than 7.0% and HBA1c more than or equal to 7.0%. The outcome of the study indicates significant correlation of HBA1c with selected haematological parameters. This could make routine haematological parameters a cost-effective means of predicting poor glucose control in diabetes mellitus patients.

Correlation of Tinnitus Severity Index and Tinnitus Handicap Inventory with Hematological Parameters in Patients with Subjective Tinnitus.

Introduction Tinnitus etiopathogenesis is still unclear and treatment options are controversial despite current advances in medicine. Objectives To analyze the correlation between patients' symptom scores, systemic inflammation, and trombosis biomarkers. Methods In this prospective study, we evaluated the degree of complaints of subjective tinnitus patients with the tinnitus severity index (TSI) and tinnitus handicap inventory (THI), and correlated these symptom scores with hematological parameters such as the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean thrombocyte volume (MPV), and platelet distribution width (PDW). Results A total of 44 patients with subjective tinnitus, 25 (56.8%) men and 19 (43.2%) women, were included in this study. The mean age of the patients was 42.3 ± 14.8 years. When the correlation between TSI and NLR, PLR, PDW, and MPV values of the patients were analyzed, no statistically significant correlation was found between TSI, NLR, and PLR ( p > 0.05). However, there was a statistically weak positive correlation between TSI, MPV, and PDW.( p < 0.05). When the correlation between THI and NLR, PLR, PDW, and MPV values of the patients were analyzed, no statistically significant correlation was found between THI, NLR, and PLR ( p > 0.05). There was a statistically weak positive correlation between THI, MPV, and PDW ( p < 0.05). Conclusion We were unable to detect any relationship between systemic inflammation markers (NLR and PLR) and symptom scores, but a weakly positive correlation was observed between thrombosis markers (MPV and PDW) and symptom scores, and as the subclinical thrombosis markers elevated, so did the symptom scores.

Lymph node ratio and hematological parameters predict relapse-free survival in patients with high grade rectal neuroendocrine neoplasms after radical resection: a multicenter prognostic study

BackgroundThe prognostic nutritional index (PNI), alkaline phosphatase (ALP), and lymph node ratio (LNR) are reportedly related to prognosis. The aim of this study was to elucidate the clinical importance of the LNR and hematological parameters in patients with high grade rectal neuroendocrine neoplasms (HG-RNENs) who were undergoing radical resection.MethodsWe reviewed the medical records of patients with HG-RNENs from 17 large-scale medical centers in China (January 1, 2010–April 30, 2022). A nomogram was constructed by using a proportional hazard model. Bootstrap method was used to draw calibration plots to validate the reproducibility of the model. Concordance index (C-Index), decision curve analysis (DCA), and time-dependent area under the receiver operating characteristic curve (TD-AUC) analysis were used to compare the prognostic predictive power of the new model with American Joint Committee on Cancer (AJCC) TNM staging and European Neuroendocrine Tumor Society (ENETS) TNM staging.ResultsA total of 85 patients with HG-RNENs were enrolled in this study. In the 45 patients with HG-RNENs who underwent radical resection, PNI ≤ 49.13 (HR: 3.997, 95% CI: 1.379–11.581, P = 0.011), ALP > 100.0 U/L (HR: 3.051, 95% CI: 1.011–9.205, P = 0.048), and LNR > 0.40 (HR: 6.639, 95% CI: 2.224–19.817, P = 0.0007) were independent predictors of relapse-free survival. The calibration plots suggested that the nomogram constructed based on the three aforementioned factors had good reproducibility. The novel nomogram revealed a C-index superior to AJCC TNM staging (0.782 vs 0.712) and ENETS TNM staging (0.782 vs 0.657). Also, the new model performed better compared to AJCC TNM staging and ENETS TNM staging in DCA and TD-AUC analyses.ConclusionsLNR, ALP, and PNI were independent prognostic factors in patients with HG-RNENs after radical resection, and the combined indicator had better predictive efficacy compared with AJCC TNM staging and ENETS TNM staging.

Comparative Study of Hematological Parameters and Biomarkers of Immunity and Inflammation in Patients with Psoriasis and Atopic Dermatitis.

Background and Objectives: There are no studies regarding comparative analysis of hematological parameters in patients with psoriasis (PsO) and atopic dermatitis (AD), whereas studies examining serum biomarkers of immunity and inflammation in these entities are scarce and contradictory. We aimed to compare such parameters in patients with PsO and AD. Materials and Methods: Patients with PsO (n = 40) and AD (n = 40) were consecutively included in this cross-sectional study. Hematological parameters and biomarkers of immunity and inflammation (interferon-gamma (IFN-γ), interleukine (IL)-22 and C-reactive protein (CRP)) were determined. Results: While the mean corpuscular volume (MCV) was higher in the PsO group vs. the AD group (p < 0.05), there was no difference in the other examined parameters between groups. A higher neutrophil-to-lymphocyte ratio (NLR) was found in patients with AD > 50 years vs. patients with PsO of similar age (p < 0.05). Higher IL-22 levels were found in patients with AD < 50 years vs. patients with PsO of similar age (p < 0.05). Lower IL-22 levels were found in patients with AD > 50 years vs. patients with AD < 50 years (p < 0.05). Patients with PsO and with comorbidities had lower platelets (PLT), plateletcrit (PCT) and platelet-to-lymphocyte ratio (PLR), whereas lymphocytes, red cell distribution width-to-PLT ratio (RPR) and mean platelet volume/PLT ratio (MPR) were higher vs. PsO patients without comorbidities. Patients with AD and with comorbidities had lower PCT and PLR, whereas RPR was higher vs. AD patients without comorbidities. Conclusions: A higher pro-inflammatory state (i.e., higher NLR and IL-22) was found in AD vs. PsO in age-specific groups. A higher pro-inflammatory state (i.e., as reflected by platelet indexes) was found in both diseases with comorbidities.

Clinical role of vitamin D, vitamin B12, folate levels and hematological parameters in patients with sudden sensorineural hearing loss

Background Sudden sensorineural hearing loss (SSNHL), which is frequently observed in otolaryngology clinics, is characterized by sudden onset hearing loss that can develop within hours or days. Its etiology is still not fully understood. Aims/objectives This research aims to identify prognostic biomarkers that can be utilized to assess the progress of SSNHL as well as circumstances that may predispose individuals to the disease. Materials and methods Between 1 January 2019 and 1 October 2020, patients diagnosed with SSNHL in our clinic and a control group consisting of healthy people were examined retrospectively. The files of the groups were examined and the levels of hemoglobin, Neutrophil-Lymphocyte Ratio (NLR), ferritin, iron, iron binding capacity (UIBC), vitamin D, vitamin B12, folate were statistically compared with the control group. In addition, the effect of the parameters studied in the patient group on the degree of recovery was examined. Results There was no statistically significant difference between the groups in terms of mean age and gender distribution (p > .05). NLR level of the patient group was higher than the control group (p < .05). Vitamin D level of the patient group was lower than the control group (p < .05). NLR and vitamin D levels had no effect on the degree of recovery (p > .05). There was no significant difference between the groups in terms of other parameters (p > .05). Conclusions and significance We think that our study can be a guide for adding vitamin D as a routine laboratory test in patients with SSNHL. In addition, we think that NLR value can be used as a marker in patients with SSNHL. It is recommended to investigate the role of vitamin D supplementation in better and faster response in these patients.

Re-evaluation of the risk of venous thromboembolism after COVID-19 vaccination using haematological criteria

An elevated risk of venous thromboembolism (VTE) following a first dose of the ChAdOx1 adenovirus-vectored vaccine was found in a national epidemiological study in England using routine discharge diagnosis codes. Separately, the syndrome of vaccine-induced immune thrombotic thrombocytopenia (VITT) was identified using haematological criteria based on presence of thrombocytopenia, significantly elevated D-dimers and development of anti-PF4 antibodies. To re-evaluate risk estimates using haematological criteria, we obtained the haematology results for hospital admitted patients aged 18–64 years in 43 National Health Service trusts in England who were included in the national epidemiological study. Diagnoses were confirmed and haematological parameters obtained from local records without knowledge of vaccination status. The haematological parameters in patients admitted for a confirmed VTE following ChAdOx1 or BNT162b2 mRNA vaccination were then compared with those in a randomly selected 40% sample of unvaccinated patients with VTE. Overall, 12 (14%) of the 84 vaccinated cases had a diagnosis compatible with VITT, 11 after a first dose of ChAdOx1 and one after a first dose of BNT162b2. Thrombocytopenia (platelet count <150 × 109/L) occurred in 17 vaccinated (20%) and 4 (4%) of 108 unvaccinated patients, with all 6 cases of severe thrombocytopenia (<50 × 109/L) occurring within 42 days of a first dose of ChAdOx1. The attributable risk estimates for a cerebral venous thrombosis (CVT) or other VTE with thrombocytopenia after a first dose of ChAdOx1 vaccine were 2.82 and 9.62 per million doses respectively. However, elevated risks were also found after a first dose of ChAdOx1 for VTE without thrombocytopenia with relative incidences for CVT and other VTE of 2.67 (1.77–3.77) and 1.93 (1.57–2.35) respectively. While we identified a distinct population with features of VITT within 42 days of receiving ChAdOx1 vaccination, confirming current diagnostic criteria, we also found evidence of an increased risk of a VTE without thrombocytopenia after ChAdOx1 vaccine.

A Cross-Sectional Study of the Haematological Profile of Patients With Chronic Liver Disease (CLD).

The liver keeps haematological parameters normal and preserves haemostasis by storing iron, vitamin B-12, and, folic acid, necessary for healthy haematopoiesis. Anaemia of various aetiologies affects approximately 75% of chronic liver disease (CLD) patients, specifically caused by iron deficiency, hypersplenism, chronic diseases, autoimmune haemolysis, folic acid deficiency, aplasticity, and as a side effect of antiviral drugs. This study sought to observe the derangements in haematological parameters in patients with CLD, analyse the spectrum of anaemia in patients with CLD, and predict CLD outcomes utilizing Child-Pugh Score. This cross-sectional observational research was carried out in the Department of General Medicine, Himalayan Institute of Medical Sciences (HIMS), Dehradun, India over the course of a year. The patients with CLD who were admitted to the ward participated in the study. Most patient's blood pictures reported normocytic normochromic with thrombocytopenia (TCP) (28.7%), macrocytic hypochromic with TCP (26%), microcytic hypochromic with TCP (13.3%) and macrocytic normochromic with TCP (9.3%). The incidence of anaemia was 85.3%: mild in 12.7% patients, moderate in 55.3% patients, and severe in 17.3% patients. Interestingly, this study also builds upon others suggesting that 85.9% of CLD patients have Class C Child-Pugh Score.

Evaluation of oxidative stress and its association with drug therapy in inpatients treated for cocaine dependence

The use of cocaine affects several systems and organs of the human body and the consumption of this substance leads to an increase in the production of reactive oxygen species, and to the reduction of antioxidant defenses. The aim of this study was to evaluate the oxidative stress (OS), biochemical and hematological parameters in patients hospitalized for treatment of cocaine addiction, comparing levels at hospital admission and discharge. Forty patients were included in the study. OS was evaluated using catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GPx), total antioxidant power (FRAP), malondialdehyde (MDA), and sulfhydryl group (GS). The medications used during hospitalization were registered and their influence on the parameters of OS was analyzed. After the hospitalization period, there was an increase in GGT levels, a reduction in SOD activity, and an increase in GPx activity and FRAP levels. Carbamazepine users had higher SOD values and lower FRAP values at hospital discharge. The use of chlorpromazine caused differences in creatinine and gamma-glutamyltransferase (GGT) serum leves, and the levels of glutamic oxalacetic transaminase (TGO), MDA, and FRAP were increased at hospital discharge. Haloperidol and thiamine during hospitalization interfered with alkaline phosphatase levels. The use of risperidone caused an increase in the levels of SOD, and folic acid use was associated with lower levels of GPx and higher levels of glutamic-pyruvic transaminase (TGP) and alkaline phosphatase. Drug rehabilitation treatment was effective in decreasing oxidative damage represented by the reduction of biological markers.

COMPARISON OF DEFERASIROX AND DESFERRIOXAMINE AS IRON CHELATORS IN MULTI-TRANSFUSED PATIENTS OF Β-THALASSEMIA MAJOR

This study aimed to compare the efficacy of deferasirox and deferoxamine in improving hematological and immunological parameters in patients with transfusion-dependent β-thalassemia major. 200 patients were enrolled in the study, with 100 receiving deferasirox and 100 receiving deferoxamine. The study was conducted at Mayo Hospital, Lahore. The patients were followed up for six months, during which various hematological and immunological parameters were measured at regular intervals. The data were analyzed using appropriate statistical methods. Both deferasirox and deferoxamine effectively improved hematological and immunological parameters in patients with β-thalassemia major. However, deferasirox was more effective than deferoxamine in improving hemoglobin, red blood cell count, and hematocrit levels. In contrast, there was no significant difference between the two iron chelators in their impact on white blood cell count and platelet count. Deferasirox appears to be a more effective iron chelator than deferoxamine in improving hematological parameters in patients with transfusion-dependent β-thalassemia major
