Leukocytosis is regarded as a reliable marker of a serious disorder requiring hospitalization. However, leukocytosis often disappears once the patient is admitted to a medical ward; differential diagnosis of leukocytosis is often overlooked in the busy Emergency Room (ER) routine. We retrospectively evaluated the clinical records of 565 consecutive patients admitted to the Department of Internal Medicine (DIM) after examination in ER. Mean leukocyte count was 11.4×109/L in ER and 10.1×109/L in DIM (P<0.001). Leukocytosis was found in 53.1% of patients in ER, but in 33% of these it was no longer evident on the following day, unrelated to baseline white blood cells (WBC) count, age, sex, diagnosis, C-reactive protein level and early antibiotic treatment. A reduction in WBC count larger than 40% from baseline occurred in 13.6% of all subjects, and in 31.7% of those with transient leukocytosis. Leukocytosis in ER is frequent, but it is often transient and not associated with an infectious cause. Other causes, including psychological stress caused by the ER access itself, should be considered in the differential diagnosis.

AbstractThe added value of biomarkers, such as procalcitonin (PCT), C-reactive protein (CRP), and white blood cells (WBC), as adjuncts to clinical risk scores for predicting the outcome of patients with community-acquired pneumonia (CAP) is in question. We investigated the prognostic accuracy of initial and follow-up levels of inflammatory biomarkers in predicting death and adverse clinical outcomes in a large and well-defined cohort of CAP patients.We measured PCT, CRP and WBC on days 1, 3, 5, and 7 and followed the patients over 30 days. We applied multivariate regression models and area under the curve (AUC) to investigate associations between these biomarkers, the clinical risk score CURB-65, and clinical outcomes [i.e., death and intensive care unit (ICU) admission].Of 925 patients with CAP, 50 patients died and 118 patients had an adverse clinical outcome. None of the initial biomarker levels significantly improved the CURB-65 score for mortality prediction. Follow-up biomarker levels showed significant independent association with mortality at days 3, 5, and 7 and with improvements in AUC. Initial PCT and CRP levels were independent prognostic predictors of adverse clinical outcome, and levels of all biomarkers during the course of disease provided additional prognostic information.This study provides robust insights into the added prognostic value of inflammatory markers in CAP. Procalcitonin, CRP, and to a lesser degree WBC provided some prognostic information on CAP outcomes, particularly when considering their kinetics at days 5 and 7 and when looking at adverse clinical outcomes instead of mortality alone.

The Past

During the past few years, biomarkers have emerged as an indispensible tool in the diagnosis of pneumonia. To find an ideal diagnostic biomarker for pneumonia is not an easy task. Not only should it allow an early diagnosis of the condition, but it should also allow differential diagnosis from other noninfectious conditions. Ongoing research is being done in this field so as to put an array of biomarkers at the disposal of doctors to improve the diagnosis of pneumonia when patients present to them with cough or nonspecific symptoms which could easily be misinterpreted as symptoms of other conditions. Procalcitonin and soluble triggering receptor expressed on myeloid cells-1 have emerged as reliable diagnostic markers in pneumonia, and are better when compared to other markers, namely, C-reactive protein, leukocyte count, and proinflammatory cytokines. Many other biomarkers are being studied for their probable use in diagnosing pneumonia but have yet to prove their benefit.

AbstractAcute pancreatitis (AP) is associated with the intensive inflammatory response in white blood cells (WBC) and C-reactive protein (CRP). This paper presents the relationship between the CRP plasma concentration and the direct counts of peripheral WBC in AP during the initial five days. The study consisted of 56 patients with AP, 36 patients with mild form of AP and 20 patients with severe form of AP. ABX VegaRetic hematological analyzer was used to perform the count of blood cells, and the immunonephelometric method was performed to measure the CRP concentration levels. AP patients presented with WBC count values in the range of 3.2 − 22.4 × 103/µl and CRP concentration levels in the range 3.3 − 599.8 mg/l. The WBC count correlates with CRP levels during the entire observation period. The relationship of CRP and WBC is expressed in the following regression equation: WBC (103/µl) = 3.66 + 1.40 × logeCRP (mg/l). The highest median neutrophil count (8.15 × 103/µl) was observed on the first day. The count decreased to 5.27 × 103/µl on the fifth day. The most substantial finding in this study involved the values found for the monocytes and CRP (r= 0.53; p<0.001). Day two and day three were the highest (r=0.59, p<0.001). On day two, the regression equation for this relationship is: Monocytes (103/µl) = −0.34 + 0.21 × logeCRP(mg/l). The correlation between direct monocyte count and plasma CRP concentration in AP reflect a CRP-dependent stimulation of IL-6 release from activated blood monocytes.

Abstract Background Hematology analyzers display abnormal parameters during malaria infection providing insightful information for suspecting and assessing malaria infection. The goal of this study is to demonstrate the potential of a three-part differential hematology analyzer to assess malaria, provide information about the parasitemia, and discuss the importance of combining C-reactive protein (CRP) with hematology parameters to obtain further information about the malaria infection. Methods The present study shows the results of a case–control study during the monsoon season of years 2018 and 2019 in Mumbai, India. The study considers 1008 non-malaria febrile cases, 209 P. vivax and 31 P. falciparum positive malaria samples, five cases of mixed P. vivax and P. falciparum infection, and three co-infection cases of P. vivax and dengue. Raw data from the three-part analyzer LC-667G CRP (HORIBA) and the corresponding microscopic findings (golden standard for diagnosis of malaria) were obtained for each sample. Results The medians of platelet counts (PLT) were 102.5, 109.0, and 223.0 × 103/µL, while CRP medians were 67.4, 81.4 and 10.4 mg/L in P. vivax, P. falciparum and control groups respectively (p < 0.001 in Mann–Whitney U tests between malaria and control groups). Compared with negative samples, platelets counting less than 161.5 × 103/µL were observed on malaria patients (OR 19.12, 95% CI 11.89–30.75). Especially in P. vivax cases, an abnormal peak was frequently observed in the white blood cells (WBC) histogram around the 37fL channel. The events counted around that channel showed a linear correlation with the counting of red blood cells infected predominantly with larger parasitic forms. Parameters like CRP (rs = 0.325, p < 0.001), WBC (rs = 0.285, p < 0.001) and PLT (rs = − 0.303, p < 0.001) were correlated with the parasitemia of P. vivax samples. Between the malaria and dengue groups, the highest area under the receiver operating characteristic curve was observed on CRP (0.867, CRP ≥ 26.85 mg/L). Conclusions A three-part differential hematology analyzer has the potential to not only trigger malaria diagnosis confirmation but also assess the severity of the infection when CRP is considered.

AbstractThis study investigated acute hemodynamic, plasma volume and immunological responses to four loading protocols: sauna only, and sauna after endurance, strength or combined endurance and strength exercise. Twenty-seven healthy, slightly prehypertensive men (age 32.7±6.9 years) were measured at PRE, MID (after exercise), POST, POST30min and POST24h. The measurements consisted systolic and diastolic blood pressure, heart rate, body temperature and concentrations of high-sensitive C-reactive protein, white blood cells and plasma volume measurements. Endurance+sauna showed significant decreases in systolic blood pressure at POST (–8.9 mmHg), POST30min (–11.0 mmHg) and POST24h (–4.6 mmHg). At POST30min, significant decreases were also observed in sauna (–4.3 mmHg) and combined+sauna (–7.5 mmHg). Diastolic blood pressure decreased significantly from -5.4 to –3.9 mmHg at POST in all loadings. Plasma volume decreased significantly at MID in all exercise loadings and at POST in endurance+sauna and strength+sauna. Plasma volume increased significantly (p < 0.01) in endurance+sauna and combined+sauna at POST24h. White blood cells increased following all exercise+sauna loadings at MID, POST and POST30min, whereas high sensitive C-reactive protein showed no changes at any measurement point. The combination of endurance exercise and sauna showed the greatest positive effects on blood pressure. Both loadings including endurance exercise increased plasma volume on the next day.
