Hematological Alterations Research Articles

Machine learning algorithm approach to complete blood count can be used as early predictor of COVID-19 outcome.

Although the SARS-CoV-2 infection has established risk groups, identifying biomarkers for disease outcomes is still crucial to stratify patient risk and enhance clinical management. Optimal efficacy of COVID-19 antiviral medications relies on early administration within the initial five days of symptoms, assisting high-risk patients in avoiding hospitalization and improving survival chances. The complete blood count can be an efficient and affordable option to find biomarkers that predict the COVID-19 prognosis due to infection-induced alterations in various blood parameters. This study aimed to associate hematological parameters with different COVID-19 clinical forms and utilize them as disease outcome predictors. We performed a complete blood count in blood samples from 297 individuals with COVID-19 from Belo Horizonte, Brazil. Statistical analysis, as well as ROC Curves and machine learning Decision Tree algorithms were used to identify correlations, and their accuracy, between blood parameters and disease severity. In the initial four days of infection, traditional hematological COVID-19 alterations, such as lymphopenia, were not yet apparent. However, the monocyte percentage and granulocyte-to-lymphocyte ratio proved to be reliable predictors for hospitalization, even in cases where patients exhibited mild symptoms that later progressed to hospitalization. Thus, our findings demonstrate that COVID-19 patients with monocyte percentages lower than 7.7% and a granulocyte-to-lymphocyte ratio higher than 8.75 are assigned to the hospitalized group with a precision of 86%. This suggests that these variables can serve as important biomarkers in predicting disease outcomes and could be used to differentiate patients at hospital admission for managing therapeutic interventions, including early antiviral administration. Moreover, they are simple parameters that can be useful in minimally equipped health care units.

Effects of Free and Nanoencapsulated Benznidazole in Acute Trypanosoma cruzi Infection: Role of Cholinergic Pathway and Redox Status

Background/Objectives: The Trypanosoma cruzi infection promotes an intense inflammatory process that affects several tissues. The cholinergic system may exert a regulatory immune response and control the inflammatory process. This study aimed to evaluate the comparative effect of free and nanoencapsulated benznidazole in acute T. cruzi infection to assess hematological, biochemical, and oxidative status triggered by the cholinergic system. Methods: For this, fifty female Swiss mice were distributed in eight groups, i.e., uninfected and infected animals under four treatment protocols: untreated (control—CT); vehicle treatment (Eudragit L 100—EL-100); benznidazole treatment (BNZ); and nanoencapsulated benznidazole treatment (NBNZ). After eight treatment days, the animals were euthanized for sample collection. Results: The peak of parasitemia was at day 7 p.i., and the BNZ and NBNZ controlled and reduced the parasite rate but showed no efficacy in terms of total elimination of parasites analyzed by RT-PCR in both infected groups. The infection promotes significant anemia, leukopenia, and thrombocytopenia, which the BNZ improves. There was an increase in AChE activity during infection, leading to a pro-inflammatory response and an increase in M1 and M2 mACh receptors in the BNZ group, showing that the treatment interacted with the cholinergic pathway. In addition, a pro-oxidative response was characterized in the infection and mainly in the infected BNZ and NBNZ groups. The histopathological analysis showed significative splenomegaly and inflammatory infiltrate in the heart, liver, and spleen. Conclusions: The administration of the BNZ or NBNZ reverses hematological, hepatic, and renal alterations through cholinergic signaling and stimulates a pro-inflammatory response during acute T. cruzi infection.

Investigating the protective effects of epigallocatechin-gallate against polystyrene microplastics-induced biochemical and hematological alterations in rats

BackgroundPolystyrene microplastics (PS-MPs) are widely used and found in drinking water and food, concerns have been raised about their potential health effects, especially in causing oxidative stress and inflammation in living organisms. ObjectivesThe aim of this study was to investigate the protective effects of epigallocatechin-gallate (EGCG), a natural antioxidant and anti-inflammatory compound, against PS-MPs-induced biochemical and hematological alterations in rats. MethodsMale Wistar rats were divided into four groups: control, EGCG-treated (80 mg∙ kg-1/d), PS-MPs-exposed (0.01 mg∙kg-1/d), and PS-MPs+EGCG-treated groups. PS-MPs were orally administered for 56 days, while EGCG was given concomitantly by gavage. At the end of the treatment period, blood samples were collected for hematological and biochemical analyses. Oxido-nitrergic stress markers, including malondialdehyde (MDA), nitric oxide (NO), reactive nitrogen species (RONS) and reduced glutathione (GSH), Superoxide dismutase (SOD), catalase (CAT), as well as inflammatory markers, such as tumor necrosis factor alpha (TNF-α), interferon gamma (IFY-γ) and interleukin-10 (IL-10), were also measured in serum. ResultsTreatment with PS-MPs caused a significant increase in MDA, RONS, NO levels and a decrease in SOD, CAT and GSH levels, indicating the induction of oxido-nitrergic stress. PS-MPs also caused an increase in the levels of TNF-α, IFY-γ, MPO and decreased IL-10, indicating the induction of inflammation. Additionally, PS-MPs caused alterations in hematological and serum transaminase parameters, including a decrease in red blood cell count, hemoglobin, and hematocrit levels, neutrophil and eaosinophil and an increase in white blood cell count, lymphocyte count, AST, ALT, ALP, LDH and GGT. PS-MPs also caused disturbances in electrolyte balance and renal function markers. However, treatment with EGCG significantly attenuated these alterations induced by PS-MPs, indicating its protective effects. ConclusionThe results of this study demonstrate that EGCG can protect against PS-MPs-induced biochemical and hematological alterations in rats, possibly through its antioxidant and anti-inflammatory properties.

Effects of Gingko Biloba Extract and L-Ascorbic Acid on Some Hematological, Biochemical, and Hepatic-Architectural Alterations in Mercury Chloride Intoxicated Adult Wistar Rat.

The study investigated the effects of Ginkgo biloba and Ascorbic acid (A.A) on mercury chloride (HgCl2) toxicity in Wistar rats. Forty-two adult Wistar rats were randomly divided into seven groups (n=6). Group I served as control. Groups II–VII received 5 mg/kg of HgCl2. Groups III and IV received 100 mg/kg and 500 mg/kg of A.A respectively, while groups V and VI daily received 100 mg/kg and 500 mg/kg of EGB761 respectively. Group VII received 100 mg/kg of A.A and EGB761. All administration were done orally, once daily for 21 days. Mercury exposure caused significant (p<0.05) decreases in RBC (3.62.00±0.75), hemoglobin (8.67±0.14), and PCV (32.93±0.47) in group II when compared to the control group, while significantly (p<0.05) increasing white blood cell count (18.57±1.51). Liver function tests significantly (p<0.05) increased Alanine transaminase (1.38±1.51), Aspartate Transaminase (10.11±4.21), and Alkaline Phosphatase (1.89±0.51) in group II when compared to Control. Biochemical analysis revealed a significant (p<0.05) increase in malondialdehyde levels and a significant (P<0.05) decrease in superoxide dismutase (3.86 ± 0.69), glutathione (10.08 ± 2.13), and catalase (3.65 ± 0.2) levels in group II. However, treatment with ascorbic acid and EGB761 significantly (P<0.05) increased in Groups IV (6.15 ± 0.38); VI (6.28 ± 0.40), and VII (6.19 ± 0.41), SOD levels in Groups IV (6.15 ± 0.38); VI (6.28 ± 0.40) and VII (6.19 ± 0.41) and GSH level when compared to the HgCl2 group. Histological examination showed moderate hepatocyte necrosis in group II, while treatment with EGB761 and A.A showed moderate healing, binucleate nuclei, and a slight decrease of distorted sinusoids and normalization of liver structure. The study concludes that EGB761 and A.A have hepatoprotective effects on mercury-induced hepatotoxicity in a dose-dependent manner. The findings suggest that these antioxidants may be useful in mitigating the harmful effects of mercury exposure on the liver.

Unveiling the Potential of Silymarin, Spirulina platensis, and Chlorella vulgaris towards Cardiotoxicity via Modulating Antioxidant Activity, Inflammation, and Apoptosis in Rats

This study assessed the possible pharmacological effects of Chlorella vulgaris (Cg), Spirulina platensis (St), and silymarin (Sl) against thioacetamide (TA)-induced cardiotoxicity in rats, with a focus on their antioxidant, cardioprotective, and anti-inflammatory properties. The following is the random grouping of sixty male rats into six groups of ten animals each: the control (negative control), TA-intoxicated group (positive control; 300 mg/kg body weight (BW)), Sl + TA group (100 mg Sl/kg BW + TA), St + TA group (400 mg St/kg BW + TA), Cg + TA (400 mg Cg/kg BW + TA), and St + Cg + TA group (400 St + 400 Cg mg/kg BW + TA) were all administered for 30 days. At the start of the study, groups 2 through 6 were administered TA intraperitoneally at a dosage of 300 mg/kg BW for two consecutive days, with a 24 h gap between each dose, to induce cardiac damage. Blood samples were obtained to measure hematological parameters and perform biochemical assays, including lipid profiles and cardiac enzymes. For histopathology and immunohistochemistry determination, tissue samples were acquired. The current findings showed that TA injection caused hematological alterations and cardiac injury, as evidenced by greater serum levels of troponin I, creatine kinase-MB, and total creatine kinase (p < 0.05), as well as significantly elevated serum malondialdehyde and decreased serum total antioxidant capacity (p < 0.05) concentrations. Moreover, an increase in blood low-density lipoprotein and total cholesterol concentration (p < 0.05) was recorded in the TA group. There were alterations in the heart tissue’s histological structure of the TA group compared to the control ones. These alterations were characterized by vacuolar degeneration of myocytes, loss of cross striation, coagulative necrosis, and fibrosis of interstitial tissue, which was ameliorated by the supplementation of SI, St, and Cg. The TA-intoxicated group showed weak expression of B-cell lymphoma protein 2 (p < 0.05) and strong immunoreactivity of tumor necrosis factor-α and B-cell lymphoma protein 2-associated X (p < 0.05). However, the groups receiving Sl, St, and Cg experienced the opposite. The administration of Sl, St, Cg, and St + Cg along with TA significantly improved and restored (p < 0.05) erythrogram indices, including RBCs, hemoglobin, total leukocytic count, lymphocytes, and monocyte, to the normal control values. The administration of Sl, St, and Cg alleviated the cardiotoxicity caused by TA via reducing oxidative stress, inflammatory markers, and apoptosis in heart tissue. In summary, the current findings suggest that the treatment with Sl, St, and Cg was beneficial in ameliorating and reducing the cardiotoxicity induced by TA in rats.

The Association Between Hematological Indices and Type 2 Diabetes Mellitus in Iranian Population

Background: Hematological alterations have been observed in diabetes, with some studies showing controversial associations between specific hematologic parameters and type 2 diabetes mellitus (T2DM). Objectives: This study aims to determine the association between hematological indices, specifically white blood cell (WBC) count, red cell distribution width (RDW), and platelet distribution width (PDW), and the presence of T2DM in an Iranian population, using data from the Bandare-Kong non-communicable diseases (BKNCD) cohort. Methods: Data from the BKNCD cohort, which includes 4063 individuals aged 35 - 70 years, was used in this study. After excluding participants with conditions that could interfere with the analysis, 2318 subjects remained for final evaluation. Results: Among the 2318 individuals, T2DM was present in 530 (22.9%). Binary logistic regression analysis revealed that the odds of T2DM increased by approximately 7% for every 109/L increase in WBC count, after adjusting for variables such as occupation, age, body mass index, sex, place of residence, education, smoking, marital status, systolic and diastolic blood pressure (DBP), and physical activity (adjusted odds ratio (aOR) = 1.066, 95% confidence interval (CI) = 1.003; 1.133, P = 0.039). Additionally, elevated PDW was associated with a 63% increase in the odds of T2DM (aOR = 1.625, 95% CI 1.159; 2.279, P = 0.005), while increased RDW was associated with decreased odds of T2DM (aOR = 0.801, 95% CI 0.716; 0.895, P < 0.001). Conclusions: Elevated PDW and WBC counts in T2DM patients in this study suggest an inflammatory state and hypercoagulability. However, the paradoxically decreased RDW may be linked to poor glycemic control in these patients.

Prevalence of canine renal insufficiency: A decade-long retrospective study in and around Patna, Bihar

This retrospective study investigates the prevalence and epidemiological factors associated with renal insufficiency in dogs within Patna, Bihar, India. Out of 5,700 dogs with various illnesses, 317 were diagnosed with renal insufficiency, identified by serum creatinine levels exceeding 5 mg/dL. The study assessed the incidence of renal insufficiency across different demographics, including age, sex, breed, and season. The highest incidence was observed in dogs aged 8-10 years, with males showing a higher prevalence than females. Pomeranians (32.18%), Labrador Retrievers (25.55%), and German Shepherds (20.82%) were the most affected breeds. Seasonally, the post-monsoon period (September-November) exhibited the highest incidence (37.85%) of renal disorders. Laboratory investigations revealed significant haematological and biochemical alterations in affected dogs, including lower haemoglobin, total erythrocyte count, and packed cell volume, alongside elevated serum levels of blood urea nitrogen (BUN), creatinine, potassium, and phosphorus. Ultrasonography indicated decreased renal size and increased echogenicity in dogs with renal insufficiency. The study concludes that renal insufficiency in dogs is most prevalent in older males and certain breeds, particularly during the post-monsoon season. Regular monitoring of serum BUN and creatinine levels is recommended for early diagnosis and management of this condition.

Apodanthera glaziovii (Cucurbitaceae) Shows Strong Anti-Inflammatory Activity in Murine Models of Acute Inflammation.

Background/objectives:Apodanthera glaziovii is an endemic species from the semi-arid Brazilian, which has limited toxicological and pharmacological studies. This species belongs to a well-studied family known for its bioactive compounds used in treating inflammatory. This study aimed to identify secondary metabolites in the stems from A. glaziovii, evaluate toxicity, and investigate the anti-inflammatory potential of the stem hydroalcoholic extract (SHE-Ag). Methods: qualitative and quantitative assays were employed to identify secondary metabolites, along with chromatographic analyses and 1H and 13C NMR. Toxicity was assessed through in vitro hemolytic toxicity, in vivo genotoxicity, and oral acute toxicity tests before the pharmacological assays were conducted. Results: phytochemical screening, HPLC and NMR analyses suggested the presence of saponins of the norcucurbitacin class. The SHE-Ag exhibited no hemolytic activity and no mutagenic potential. However, in vivo toxicity at a dose of 2000 mg/kg revealed hematological and biochemical alterations, while the 500 mg/kg dose was safe. In the anti-inflammatory assays, SHE-Ag at 100 mg/kg reduced paw edema by 55.8%, and leukocyte and neutrophil migration by 62% and 68% in the peritonitis model, respectively; inflammatory cell migration by 70% in the air pouch model, outperforming indomethacin, which showed a 54% reduction. Conclusions: these findings indicate that SHE-Ag is rich in saponins, confirmed through HPLC and 1H and 13C NMR analyses. The SHE-Ag also demonstrated low toxicity. The inflammation models used showed a reduction in inflammation, pro-inflammatory cells, and edema, highlighting the significant anti-inflammatory activity of hydroethanolic extract A. glaziovii stems.

Methanolic stem-bark extracts of Adansonia digitata modulates haematological and antioxidant parameters in streptozotocin-induced diabetic rats

Background and AimDiabetes mellitus is associated with haematological abnormalities and oxidative stress, contributing to disease progression and complications. Adansonia digitata, is a traditional medicinal plant well known for its potential therapeutic properties. This study investigates the effects of methanolic stem-bark extracts of Adansonia digitata on haematological and antioxidant status in streptozotocin-induced diabetic rats. Experimental ProcedureFourty-two wistar rats were distributed into 6 groups of 7 each. Group 1 served as normal control, group 2 to 6 animals were made diabetic by intraperitoneal administration of single dose of 50 mg kg-1 streptozotocin. Group 2 served as the negative control and did not receive treatment, group 3 served as the positive control and received 150 mg kg-1 metformin (Glucophage) (standard drug), while group 4, 5 and 6 received oral treatment of 100 mg kg-1, 200 mg kg-1 and 300 mg kg-1 of Adansonia digitata stem-bark methanolic extract respectively for 21days, after which the animals were sacrificed, and blood and liver were collected for haematological analysis including White Blood cell (WBC), red blood cell (RBC), haemoglobin (HGB), hematocrit (H CT), platelet (PLT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), total bilirubin (TB), direct bilirubin(DB) and indirect bilirubin (IB) concentration and antioxidant parameters including antioxidant enzymes [catalase (CAT) and superoxide dismutase (SOD) activities] and oxidative stress marker [thiobarbituric acid reactive substance (TBARS)]. ResultsSTZ administration evoked a marked (p < 0.05) decline in the level of WBC, RBC, HGB, PLT, LYM and MCV in the diabetic rats when compared with the normal control. Howbeit, treatment with methanolic extracts of adansonia digitata stem-bark led to a profound (p < 0.05) increase in concentrations of these parameters close to the normal. In addition, STZ caused a non-significant (p > 0.05) decrease in MCH and MCHC. On the contrary, STZ caused an insignificant (p > 0.05) increase in the levels of TB and DB, but a significant (p > 0.05) increase IDB level in the diabetic control group when compared with the normal control group, while treatment with stem-bark extracts resulted in a marked (p > 0.05) fall in IDB level. Furthermore, there was a marked (P < 0.05) reduction in the activity of hepatic CAT and SOD and a considerable (P < 0.05) elevation in Malondialdehyde (MDA) level in the hepatic tissue of the diabetic control. Nonetheless, Adansonia digitata stem-bark extracts profoundly (P < 0.05) raised the activities of the enzymes and concomitantly counteracted MDA level. The extract elicited strong potency at 300 mg kg-1 which is comparable to metformin (Glucophage). ConclusionConsequently, this study advocates for the utility of Adansonia digitata extracts for the development of novel drugs for combating diabetes mellitus, associated hematological and oxidative stress complications and other ailments. Further research is needed to evaluate the clinical relevance of these effects in human subjects and to provide information on the sustained efficacy of the extracts in chronic models. Significant statementOxidative stress and hematological abnormalities are two of the consequences linked to diabetes mellitus. Anaemia and poor blood coagulation are two haematological changes that increase the risk of diabetes-related illness and death. Furthermore, oxidative stress is essential to the pathophysiology of diabetic complications such as nephropathy and cardiovascular disease. In addition, there are reports on hematological and biochemical alterations in diabetic subjects arising from the intake of synthetic antidiabetic medications.. Consequent to the safety, ease of use, efficacy, and lack of cytotoxic side effects of plants’ herbs, the study of Adansonia digitata's methanolic stem-bark extracts on haematological and antioxidant parameters in streptozotocin-induced diabetic rats is of paramount importance as the extracts' capacity to modify these parameters, will lead to the development of novel drugs that cures anemia, other blood abnormalities, and oxidative stress linked to diabetes as well as other ailments.

E3 Ubiquitin Ligase Smurf1 Regulates the Inflammatory Response in Macrophages and Attenuates Hepatic Damage during Betacoronavirus Infection.

The E3 ubiquitin ligase Smurf1 catalyzes the ubiquitination and proteasomal degradation of several protein substrates related to inflammatory responses and antiviral signaling. This study investigated the role of Smurf1 in modulating inflammation induced by Betacoronavirus infection. Bone marrow-derived macrophages (BMDMs) from C57BL/6 (wild-type) or Smurf1-deficient (Smurf1-/-) mice were infected with MHV-A59 to evaluate the inflammatory response in vitro. Smurf1 was found to be required to downregulate the macrophage production of pro-inflammatory mediators, including TNF, and CXCL1; to control viral release from infected cells; and to increase cell viability. To assess the impact of Smurf 1 in vivo, we evaluated the infection of mice with MHV-A59 through the intranasal route. Smurf1-/- mice infected with a lethal inoculum of MHV-A59 succumbed earlier to infection. Intranasal inoculation with a 10-fold lower dose of MHV-A59 resulted in hematological parameter alterations in Smurf1-/- mice suggestive of exacerbated systemic inflammation. In the lung parenchyma, Smurf1 expression was essential to promote viral clearance, downregulating IFN-β mRNA and controlling the inflammatory profile of macrophages and neutrophils. Conversely, Smurf1 did not affect IFN-β mRNA regulation in the liver, but it was required to increase TNF and iNOS expression in neutrophils and decrease TNF expression in macrophages. In addition, Smurf1-/- mice exhibited augmented liver injuries, accompanied by high serum levels of alanine aminotransferase (ALT). These findings suggest that Smurf1 plays a critical role in regulating the inflammatory response in macrophages and attenuating systemic inflammation during Betacoronavirus infection.

Stress levels, hematological condition, and productivity of plasma-producing horses used for snake antivenom manufacture: A comparison of two industrial bleeding methods

The immunization and industrial bleeding of horses are essential stages for producing snake antivenoms. In Costa Rica, the traditional method involves stimulating the antibody response of horses by periodically injecting venoms, collecting hyperimmune plasma over three consecutive bleeding days, and repeating this process every eight weeks. While this method does not cause major physical or hematological issues in horses, the associated stress has not been evaluated. We compared this traditional method with an alternative method that involves injecting venoms, collecting hyperimmune plasma in a single bleeding day, and repeating the process every two weeks. We assessed stress (via serum and fecal cortisol levels and an ethological study), hematological parameters (hematocrit and hemoglobin concentration), and plasma productivity over eight months. Serum cortisol levels remained within the normal range for both methods throughout the immunization/bleeding cycle. However, serum and fecal cortisol levels were significantly higher in horses subjected to the traditional method compared to those in the alternative method. Neither method caused significant hematological alterations. Notably, the alternative method yielded a higher volume of plasma. We concluded that adopting the alternative method ensures horse welfare while improving industrial bleeding productivity. This approach may reduce costs and improve the availability of this essential treatment for vulnerable populations.

Relationship between chronic diseases, hair cortisol concentration and welfare of housed dairy goats

The aim of this study was to evaluate the relationship between seroprevalence of chronic diseases, hair cortisol concentration (HCC), and welfare of dairy goats housed throughout a productive cycle. Sixty multiparous dairy goats, over four years old, were selected. An animal welfare assessment was conducted using health indicators for goats, according to the AWIN protocol. Blood samples were also collected for haematology and determination of seroprevalence of chronic diseases, hair samples for determination of HCC, milk samples for chemical composition and somatic cell counts, and faecal samples for parasite load. Small Ruminant Lentivirus (SRLv) had a prevalence of 71.66%, Mycobacterium avium subspecies paratuberculosis (MAP) of 5%, Leptospira interrogans of 40% and Ovine Gammaherpesvirus type 2 (OvHV-2) of 50%. The percentages of goats that tested positive for one, two or three diseases were 31.67%, 50% and 11.66%respectively. Haematological alterations included hyperproteinaemia (84.94 ± 1.58 g/L) and hyperfibrinogenaemia (6.11± 0.65 g/L) for those with one or two diseases, with significant differences being found (P &lt; 0.05). The welfare indicatorsrelated to health and the number of diseases were poor body condition, poor coat, poor udder conformation, andmucosal lesions (P &lt; 0.05). However, no significant differences were observed between HCC and the number of chronicdiseases in dairy goats (P &gt; 0.05). Higher concentrations of cortisol in hair were found at 150 days of lactation (16.65 ± 1.39pg/mg) compared to the mating season (9.55 ± 0.04 pg/mg) (P &lt; 0.05). No associations were found (P &gt; 0.05) betweenthe production, composition, and somatic cell counts in milk and cortisol concentrations and diseases. It was concludedthat the presence of chronic diseases in goats did not influence hair cortisol concentrations, possibly due to an effect ofadaptive tolerance to diseases, as occurs in other domestic species; however, there was an effect of the productive stage.

Oxidative Stress, Hematological and Histopathological Alterations Recovery by Methanolic Extract of Celtis Occidentalis L. Leaves in Paracetamol-Induced Hepatic Injury in Rabbit

Background: Paracetamol overdose is a leading cause of hepatotoxicity, resulting in oxidative stress and liver damage. Exploring natural therapeutic agents like Celtis occidentalis for their hepatoprotective effects is essential to mitigate these effects.Objective: To evaluate the hepatoprotective, antioxidant, and nephroprotective effects of methanolic extract of Celtis occidentalis leaves in paracetamol-induced hepatic injury in rabbits.Methods: The study involved 40 male rabbits divided into eight groups, including control, paracetamol (2 g/kg), and various doses of Celtis occidentalis extract (100, 200, and 300 mg/kg) with or without silymarin (50 mg/kg). The extract's antioxidant potential was assessed using DPPH and ABTS assays. Hepatic and renal function tests, lipid profiles, and hematological parameters were measured, and histopathological evaluations of liver tissues were conducted.Results: The extract showed significant antioxidant activity, with 87.7% DPPH and 89.8% ABTS scavenging at 1000 µg/mL. It reduced ALT, AST, ALP, and bilirubin levels significantly (P&lt;0.05). High dose extract normalized lipid profiles and improved hematological parameters compared to paracetamol alone.Conclusion: Celtis occidentalis extract exhibited potent hepatoprotective effects, normalizing liver function and mitigating oxidative stress, suggesting its potential use in human healthcare for liver protection.

Gender Differences in the Effects of Cadmium Exposure on Hematological Parameters in Wistar Rats

This study aims to investigate the gender dimorphism in cadmium exposure on hematological parameters in male and female Wistar rats. Twenty Wistar rats (120g-150g) were divided into four groups: male control, male cadmium-treated, female control, and female cadmium-treated. Cadmium chloride (50 mg/kg) was administered orally to the experimental groups for 45 days. Hematological parameters were analyzed using an auto hematological analyzer. Data were statistically evaluated using two-way ANOVA with significance set at p &lt; 0.05. Cadmium exposure significantly increased white blood cell (WBC) counts in male rats compared to controls, with notable decrease in neutrophils and an increase in lymphocytes. Female rats showed significant increase in monocyte and basophil levels. Furthermore, red blood cell (RBC) parameters showed significant reductions in hemoglobin concentration, mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH) in female cadmium-treated rats. No significant effects were observed on platelet count or distribution width in both male and female rats. The study concluded there are gender-specific hematological alterations due to cadmium exposure in Wistar rats. These findings underscore the need for gender-specific approach in the understanding and amelioration of cadmium toxicity.

Pediatric Sickle Cell Disease Patients' Hematological Changes during Vaso-Occlusive Crises (VOCS) Versus Steady State

Background: The primary acute outcome of sickle cell disease (SCD) is a vaso-occlusive crisis (VOC) with extreme pain. More than three vaso-occlusive crisis (VOC) hospitalizations in a year increase the risk of early death. The objective of the study was to evaluate the hematological alterations in complete blood count (hemoglobin, red blood cell indices, white blood cell count, and platelets) and C-reactive protein levels during vaso-occlusive crises in patients with sickle cell anemia (HbSS) compared to a stable symptomatic state. Methodology: This study is a prospective descriptive study conducted in a hospital setting. During the period from February to June 2015, a Sudan Sickle Cell Anemia Center (SSCAC) in North Kordofan State, Sudan, treated a total of 100 patients with sickle cell anemia. Out of these patients, 74 had a vaso-occlusive crisis and 26 had a steady-state condition. All patients had measurements of their complete blood count (CBC) and C-reactive protein (CRP) levels. We calculated the average values of CBC and CRP level counts during vaso-occlusive crises and compared them to the values during steady state using independent t-tests. We analyzed the collected data using the Statistical Tool for Social Sciences (SPSS) software tool, specifically version 13. Results: The statistical analysis of the patient sample during vaso-occlusive crisis and steady state revealed that the concentration of hemoglobin (Hb) was 6.55 g/dl ± 1.3 and 9.8 g/dl ± 2.4, respectively, with a p-value of 0.000. The packed cell volume (PCV) was 20.4% ± 3.9 and 30.7% ± 7.1, respectively, with a p-value of 0.000. The red blood cell (RBC) count was 2.5×106/µl ± 0.57 and 3.9×106/µl ± 1.1, respectively, with a p-value of 0.000. A lot more white blood cells (WBC) were present in vasoocclusive than in steady state, with numbers 19.36 x 109/l ± 10.645 and 76.76 x 109/l ± 20.19, respectively, and a P-value of ≤0.000. There was a notable statistical disparity in the platelet count, with values of (357.108109/l ± 162.838) and (290.4610×9/l ± 124.40), with a P value of 0.05. In vaso-occlusive crises, the amounts of hemoglobin, packed cell volume (PCV), and red blood cells (RBCs) are lower than they are in the steady-state phase. Conversely, white blood cell (WBC) and platelet levels are much greater in patients experiencing vaso-occlusive crises compared to those in a steady state. The levels of C-reactive protein (CRP) were significantly different between patients experiencing vaso-occlusive crises and those in a stable condition.

A Comparative Study of Coagulation Profiles in Preeclamptic and Normotensive Patients in Relation to Maternal and Fetal Outcomes.

Background Hypertensive complications during pregnancy play a significant role in the increased rates of maternal and perinatal morbidity and mortality on a global scale. Preeclampsia is characterized by elevated blood pressure levels and the presence of protein in the urine and is associated with diverse hematological alterations, particularly impacting the coagulation cascade. The primary objective of this research was to conduct a comparative analysis of the coagulation profiles and pregnancy outcomes in women with preeclampsia versus those with normal blood pressure during pregnancy. Methods This was a prospective case-control study with 74 participants across two groups, conducted from September 2022 to May 2024. The participants were enrolled and divided into two groups, with 37 in the clinically diagnosed preeclampsia group and 37 in the normotensive group. Coagulation parameters including platelet count, bleeding time, clotting time, international normalized ratio (INR), activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen levels, alkaline phosphatase (ALP) levels, D-dimer levels, and fibrin degradation products (FDP) levels were assessed. Maternal and neonatal outcomes were also compared. In our study, we comprehensively examined both maternal and neonatal outcomes in preeclampsia and normotensive groups. Maternal complications analyzed included mode of delivery, incidence of eclampsia, placental abruption, hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome, postpartum hemorrhage (PPH), and peripartum cardiomyopathy (PPCM). For neonatal outcomes, we assessed birth weight, appearance, pulse, grimace, activity, and respiration (APGAR) scores, and the duration of neonatal intensive care unit (NICU) stays. Results The results showed that mean platelet count was significantly lower in the preeclampsia group (151,503 ± 59,875/µL) compared to the normotensive group (245,405 ± 69,021/µL) (p < 0.0001). Bleeding time, INR, APTT, and PT showed significant elevation in the preeclampsia group, indicating a slower coagulation process. Fibrinogen levels, ALP levels, and D-dimer levels were significantly higher in the preeclampsia group (p < 0.0001). The preeclampsia group had a higher rate of cesarean sections (65% vs. 24%) and lower neonatal birth weights (mean 2.3 kg vs. 2.5 kg). APGAR scores were comparable between groups, but a higher number of neonates went to the NICU in the preeclampsia group (64.9% vs. 10.8%). The preeclampsia group also showed higher rates of low birth weight (27%), intrauterine growth restriction (27%), respiratory distress syndrome (10.8%), and asphyxia (5.4%). Conclusion Preeclampsia is associated with significant hematological changes, particularly in coagulation parameters, and adverse fetomaternal outcomes. Early identification and monitoring of these changes are crucial for timely intervention and improving maternal and neonatal health outcomes.
