AbstractBackground and aimsPrevious studies have demonstrated that elevated cholesterol results in increased white blood cell counts in mouse models. However, there is insufficient evidence to support this in humans. We, therefore, investigated the relationship of plasma lipids with white blood cell counts (basophils, eosinophils, monocytes, neutrophils and lymphocytes) in the Multi-Ethnic Study of Atherosclerosis (MESA).MethodsThe analysis included 2873 MESA participants at visit 5 with a complete white blood count and differential analysis. The cross-sectional association of total cholesterol, LDL cholesterol, HDL cholesterol and triglyceride levels with different white blood cell counts was analyzed by multivariable linear regression.ResultsAfter adjusting sociodemographic and confounding factors including red blood cells counts, platelet counts, use of lipid-lowering medication, CVD risk factors and other lipid measures, and multiple testing correction, a 1-SD increment in total cholesterol and LDL cholesterol was associated with 2.8% and 2.3% (both p<0.001) lower total white blood cell counts. The same increment in ln-transformed triglyceride levels was associated with 2.3% higher total white blood cell counts, 2.9% higher lymphocyte counts and 2.7% lower monocyte counts (all p<0.001). HDL cholesterol was not associated with any white blood cell counts. Similar results were obtained after excluding participants taking lipid-lowering medication.ConclusionsWhilst significant associations were observed, the heterogenous and modest nature of the relationships between plasma lipid levels and white blood cell populations make it hard to support the hypothesis that lipids are in the causal pathway for leukogenesis.

Introduction: Haematological and serum biochemical profiles of dogs are essential in the diagnosis and monitoring of systemic disease in veterinary medicine. The aim of this study was to determine the baseline haematological, serum biochemical and some urine parameters in clinically healthy dogs presented to the Veterinary teaching hospital (VTH), Ahmadu Bello University (A.B.U.), Zaria, Nigeria. Methods: Thirty apparently healthy dogs comprising of 19 males and 11 females aged between 9 to 36 months were sampled in this study. Whole blood was collected via cephalic venepuncture for determination of haematological parameters. Serum was processed from the whole blood to determine the concentrations of serum metabolites, serum electrolytes, blood urea nitrogen (BUN)/creatinine ratio, anion gap (AG) as well as serum activities of liver enzymes. Urinalysis was done using urine. Data was analysed using Graph pad prism version 5.2. Mean values were determined. Results: No significant (p > 0.05) differences related to sex were observed in the values of packed cell volume (PCV), haemoglobin (Hb) concentration, red blood cell counts (RBC), mean corpuscular volume (MCV) and mean corpuscular haemoglobin concentration (MCHC), differential and total white blood cell counts. The PCV (p < 0.005), Hb (p < 0.05) and Hb (p < 0.01) of the adults were significantly higher in the young Nigerian indigenous dogs. However, the MCV, MCHC, differential and total white blood cell counts were insignificant in both age groups. Significance: These baseline data would help clinicians to recognize deviations from normal clinicopathological parameters especially in Nigerian Indigenous dogs.
