Aging an aqueous solution of nitrogen mustard up to 3 days did not alter significantly its ability to decrease the white blood cell count, body weight, or the growth of the established Walker 256 tumor in the rat. There was a direct relationship between the decrease in white blood cell count and depression of tumor growth but not between the depression of body weight and tumor growth. The acidity of aqueous nitrogen mustard (0.5 mg/ml) increased exponentially with time up to 100 days but was not related to the ability to decrease the white blood cell count, body weight, or tumor growth.

Saccharomyces boulardii is a probiotic yeast used as a nutritional supplement. Co-trimoxazole, is a broad-spectrum antimicrobial agent used in the prophylaxis and treatment of infections.The goal of this study was to evaluate the individual and interactive effects of probiotic Saccharomyces boulardii and co-trimoxazole on some haematological parameters in albino rats. Thirty (30) albino Wistar rats weighing 150-200g were divided into five groups; Basal, A, B, C, and D, with six animals in each group. Group A (control) was given a normal rat pellet (standardized feed) and clean water (pH 6.5- 8.5). Group B was administered 5.5mg/kg body weight of the commercial probiotics (Saccharomyces boulardii). Group C was administered 4.4mg/kg body weight of co-trimoxazole. Group D was administered 5.5mg/kg body weight of the commercial probiotics and 4.4mg/kg body weight of co-trimoxazole. All administrations were done using a gavage tube for 15 days. Blood samples were collected for analysis on days 0, 5 and 15. The results showed that Saccharomyces boulardii caused a significant increase (P<0.05) in total white blood cell count and packed cell volume of the treated groups at day 5. On day 15, the total white blood cell count (10.67±0.66), packed cell volume (43.23±0.47), platelet count (932±38.89) and mean platelet volume (8.53±0.38) showed a significant increase (P<0.05) in the probiotic group. The co-trimoxazole group showed a significant reduction (P<0.05) in the packed cell volume and total white blood cell count. This study shows that Saccharomyces boulardii has a positive effect on the haematological profile of the test animals.

The purpose of the study: to assess the morphological changes in the lungs depending on the content of clozapine and its metabolites in the lungs and serum.Materials and methods. The experiments were performed on male outbred rats weighing 290-350 g at the age of 20 weeks (n=15). The animals were divided into 3 groups: Group 1 — reference group (intact rats) (n=5); Group 2 -poisoning with clozapine (n=5); Group 3 — poisoning with a combination of clozapine with ethanol (n=5). Clozapine was administered orally at a dose of 150 mg per kg of animal's body weight under general anesthesia; alcohol was administered together with clozapine orally at a dose of 5 ml per kg of animal's body weight. Further study was carried out 24 hours after administration of drugs to animals of the 2nd and 3rd groups. After euthanasia of the animals by decapitation, tissue samples of lungs were embedded in paraffin according to the standard technique. Then 5-μm thick histological sections were made and examined using light microscopy with the aid of a Nikon Eclipse E400 microscope equipped with a video system based on the Watec 221S camera (Japan) at magnification of X200 and X400. The following pathological patterns were assessed: disorder of blood circulation (hyperemia, hemorrhage, and sludge), the presence of atelectasis and dystelectasis, the presence of emphysema, the cellular response (an increase in the white blood cell count), and desquamation of epithelium into the lumen of the bronchi. A chemical and toxicological study was performed on a high-performance liquid chromatograph with mass detector Agilent Technologies 430 Triple Quad LC/MS (Germany). To obtain chromatograms, the following software was used: Agilent Mass Hunter Workstation for series tripple Quadrapole vers. B06.00 build 6.0.6.25.4sp4.The following software was used for processing chromatograms: Agilent Mass Hunter Quantitive Analysis vers. B 07.00 build 7.0.457.0. Serum and lung homogenate levels of clozapine, norclozapine, and clozapine-N — oxide were evaluated.Results. In 24 hours, animals in the 2nd group exhibited atelectasis and dystelectasis in the lung tissue, and leukocyte infiltration; in the 3rd group, arterial hyperemia, cellular response (an increase in the white blood cell count), atelectasis and dystelectasis, and thickening of interalveolar septa were revealed. In 24 hours, in the lungs of animals of the 3rd group, the concentration of clozapine increased by 22.2-fold, norclozapine by 6.6-fold, and clozapine-Noxide by 6.2-fold as compared to the 2nd group; in serum it increased by 5.7-, 2.0and 4.6-fold, respectively.Conclusion. In the case of poisoning with clozapine in combination with ethanol, a complex of pathological changes in the lungs develops, which is more severe than the isolated effect of clozapine administered as a single drug. The concentration of clozapine and its metabolites in the lung tissue and blood serum is higher when it enters the body in combination with ethanol.

Increasing evidence shows that white blood cells are associated with the risk of coronavirus disease 2019 (COVID-19), but the direction and causality of this association are not clear. To evaluate the causal associations between various white blood cell traits and the COVID-19 susceptibility and severity, we conducted two-sample bidirectional Mendelian Randomization (MR) analyses with summary statistics from the largest and most recent genome-wide association studies. Our MR results indicated causal protective effects of higher basophil count, basophil percentage of white blood cells, and myeloid white blood cell count on severe COVID-19, with odds ratios (OR) per standard deviation increment of 0.75 (95% CI: 0.60–0.95), 0.70 (95% CI: 0.54–0.92), and 0.85 (95% CI: 0.73–0.98), respectively. Neither COVID-19 severity nor susceptibility was associated with white blood cell traits in our reverse MR results. Genetically predicted high basophil count, basophil percentage of white blood cells, and myeloid white blood cell count are associated with a lower risk of developing severe COVID-19. Individuals with a lower genetic capacity for basophils are likely at risk, while enhancing the production of basophils may be an effective therapeutic strategy.

Background: Psoriasis is associated with accelerated non-calcified coronary plaque burden (NCB) by coronary computed tomography angiography (CCTA). Machine learning (ML) algorithms have been shown to effectively identify cardiometabolic variables with NCB in cross-sectional analysis. Objective: To use ML methods to characterize important predictors of change in NCB by CCTA in psoriasis over 1-year of observation. Methods: The analysis included 182 consecutive patients with 80 available variables from the Psoriasis Atherosclerosis Cardiometabolic Initiative, a prospective, observational cohort study at baseline and 1-year using the random forest regression algorithm. NCB was assessed at baseline and 1-year from CCTA. Results: Using ML, we identified variables of high importance in the context of predicting changes in NCB. For the cohort that worsened NCB (n = 102), top baseline variables were cholesterol (total and HDL), white blood cell count, psoriasis area severity index score, and diastolic blood pressure. Top predictors of 1-year change were change in visceral adiposity, white blood cell count, total cholesterol, c-reactive protein, and absolute lymphocyte count. For the cohort that improved NCB (n = 80), the top baseline variables were HDL cholesterol related including apolipoprotein A1, basophil count, and psoriasis area severity index score, and top predictors of 1-year change were change in apoA, apoB, and systolic blood pressure. Conclusion: ML methods ranked predictors of progression and regression of NCB in psoriasis over 1 year providing strong evidence to focus on treating LDL, blood pressure, and obesity; as well as the importance of controlling cutaneous disease in psoriasis.

Reactive Thrombocytosis

Abstract Background Enoxaparin is an anticoagulant that falls in the class of medications called low molecular weight heparins (LMWHs), and is used to prevent or treat patients with deep vein thrombosis (DVT) and pulmonary embolism. Enoxaparin is the most widely used LMWH for DVT prophylaxis following knee or hip replacement surgery. Common side effects of enoxaparin include bleeding, petechiae at the injection site, and thrombocytopenia. However, reactive thrombocytosis is a rarely reported adverse reaction. We managed a patient who developed enoxaparin-associated thrombocytosis, which was completely resolved after treatment cessation. Case presentation A 78-year-old female was hospitalized for post-hip replacement rehabilitation. Low molecular weight heparin 40 mg/day was administered subcutaneously to prevent deep venous thrombosis (DVT). At admission, her platelet count was normal (228 × 109/L) and her white blood cell count was slightly elevated (12.91 × 109/L). Seven days after admission, the patient developed thrombocytosis, which peaked on the 14th day (836 × 109/L), while her white blood cell count had returned to normal (8.86 × 109/L). Her therapeutic regimen was reviewed, and enoxaparin was identified as a potentially reversible cause of reactive thrombocytosis. Switching from enoxaparin to rivaroxaban lead to a gradual decrease in the patient’s platelet count, which eventually returned to normal levels 16 days after enoxaparin was discontinued. No complications secondary to thrombocytosis was observed, and no conclusion was reached on the use of small doses of aspirin for antithrombotic therapy under these circumstances. Conclusion Enoxaparin-induced reactive thrombocytosis should be suspected in patients with thrombocytosis following enoxaparin administration as an anticoagulant to prevent certain complications.
