Asociación entre la variación de glóbulos blancos y las manifestaciones clínicas, anticuerpos e infecciones en adultos con lupus eritematoso sistémico / White blood cells count variation in systemic lupus erythematosus: its association to disease manifestations, antibodies and risk of infections

Introducción: la asociación de leucopenia, linfopenia y neutropenia con la presencia de autoanticuerpos, manifestaciones clínicas e infecciones en pacientes con lupus eritematoso sistémico (LES) no está bien establecida. Los objetivos de este estudio fueron analizar los cambios en los recuentos de leucocitos y linfocitos en pacientes con LES y su asociación con manifestaciones clínicas, autoanticuerpos y riesgo de infecciones. Materiales y métodos: se recolectaron retrospectivamente los valores de leucocitos, linfocitos y neutrófilos. Se agruparon a los pacientes en cinco categorías: recuento de glóbulos blancos normales, leucopenia (persistente o intermitente) y linfopenia (persistente o intermitente). Se registraron las manifestaciones clínicas, los autoanticuerpos acumulados, el daño, la mortalidad, las infecciones y los tratamientos inmunosupresores recibidos de cada paciente. Resultados: se incluyeron 89 pacientes. La linfopenia (89%) fue la anormalidad más frecuente. La leucopenia intermitente y la persistente se detectaron en el 44% y en el 11% de los pacientes, respectivamente. La linfopenia intermitente y la persistente se hallaron en el 44% y en el 45% de los casos. En el análisis univariado, la presencia de rash discoide se asoció a leucopenia (20,4 vs. 5,1; p=0,059) y el tratamiento con mofetil micofenolato a un recuento normal de leucocitos (p=0,046). El compromiso neurológico se asoció a recuento normal de linfocitos (22,2% vs. 0% y 7,5%; p=0,027); los pacientes con anti-RNP (anti ribonucleoproteína nuclear) presentaron más frecuentemente linfopenia persistente (47% vs. 15,4% y 20%; p=0,007). Ninguno de los grupos se asoció a una mayor prevalencia de infecciones. En el análisis multivariado, el mofetil micofenolato se asoció negativamente a leucopenia (OR 0.33 IC 95% 0,1-0,9; p=0,042) y el compromiso neurológico se asoció negativamente a linfopenia (OR 0.08; p=0,022). Conclusiones: en el análisis univariado, el rash discoide se asoció a leucopenia y el anti-RNP a linfopenia. Al ajustar por otras variables significativas, el tratamiento con mofetil micofenolato se asoció a un recuento normal de leucocitos, mientras que las manifestaciones neurológicas se relacionaron a linfocitos normales. No se demostró asociación de las infecciones con ninguno de los grupos.

Introduction: leukopenia, lymphopenia and neutropenia association to clinical manifestations and infections in systemic lupus erythematosus (SLE) is not well defined. The objectives were to analize leucocytes and lymphocytes variations in SLE patients and their association to clinical manifestations, autoantibodies and infections risk. Materials and methods: total white blood cell (WBC) count, lymphocyte, and neutrophils counts were collected retrospectively. Data were grouped into normal WBC cell count, persistent or intermittent leucopenia and lymphopenia. Disease manifestations, accumulated autoantibodies, damage, mortality, infections and immunosuppressants ever received were registered. Results: study sample included 89 patients. Lymphopenia (89%) was the most common abnormality. Intermittent and persistent leukopenia were detected in 44% and 11% cases. Intermittent and persistent lymphopenia were found in 44% and 45% cases. In univariate analysis, discoid rash was associated to leukopenia (20.4 vs 5.1 p=0.059) and mycophenolate treatment to normal leukocyte count (p=0.046). Patients with neurological disorder tended to have normal lymphocyte counts rather than intermittent or persistent lymphopenia (22.2% vs 0% and 7.5% p=0.027); patients with anti-RNP tended to belong to the persistent lymphopenia group (47% vs 15.4% and 20% p=0.007). Infections were not associated to any of the categories. In multivariate analysis mycophenolate was negatively associated to leukopenia (OR 0.33 95% CI 0.1-0.9 p=0.042) while neurological disorder was negatively associated to lymphopenia (OR 0.08 p=0.022). Conclusions: in univariate analysis, discoid rash was associated to leukopenia and anti-RNP to lymphopenia. When adjusted to other significant variables, mycophenolate was related to normal leukocyte while neurological manifestations were to normal lymphocyte counts. Infections were not associated to any of the categories.

BLOOD CELL MORPHOLOGY AND LEUKOCYTE DIFFERENTIAL OF MORELET'S CROCODILE (Crocodylus moreletii) (CROCODYLIDAE) / Morfología de células sanguíneas y recuento leucocitario del cocodrilo de Morelet (Crocodylus moreletii) (CROCODYLIDAE)

ABSTRACT The objective of the study was to determine the morphological characteristics of peripheral blood cells (erythrocytes, leukocytes, thrombocytes) and the leukocyte differential count (heterophils, eosinophils, basophils, lymphocytes, monocytes, azurophils) of captive Morelet's crocodiles (Crocodylus moreletii) from Veracruz, Mexico. Peripheral blood from 80 apparently healthy farmed crocodiles (39 subadults [19 females, 20 males] and 41 adults [18 females, 23 males]) was examined for morphology through stained blood smears and manual count was used for the leukocyte differential. Blood was collected during the non-breeding (n = 42) and breeding (n = 38) seasons. Blood examination indicated similar morphological characteristics of blood cells in subadult and adult individuals and in females and males in both seasons. Erythrocytes were the largest blood cells and lymphocytes the smallest. The leukocyte differential count showed that lymphocytes were the most abundant leukocytes and basophils the least numerous. The percentages of some leukocytes showed difference by season (non-breeding and breeding) in subadult and adult males (p < 0.05) and by size (subadults and adults) in males and females but only in the non-breeding season (p < 0.05). The leukocytes that showed the greatest variation were lymphocytes, heterophils and eosinophils. The knowledge of blood cell morphology and the leukocyte differential count in healthy farmed Morelet's crocodiles will allow the accurate diagnosis of some diseases of captive and wild individuals.

RESUMEN El objetivo del estudio fue determinar las características morfológicas de células sanguíneas periféricas (eritrocitos, leucocitos, trombocitos) y el conteo diferencial de leucocitos (heterófilos, eosinófilos, basófilos, linfocitos, monocitos, azurófilos) del cocodrilo de Morelet (Crocodylus moreletii) mantenido en cautiverio en Veracruz, México. Se examinó sangre periférica de 80 cocodrilos aparentemente sanos criados en granja (39 subadultos [19 hembras, 20 machos] y 41 adultos [18 hembras, 23 machos]) mediante frotis sanguíneos teñidos para determinar la morfología celular y mediante conteo manual para el diferencial de leucocitos. La sangre se recolectó durante las temporadas no reproductiva (n = 42) y reproductiva (n = 38). El examen sanguíneo indicó similar morfología de células sanguíneas en individuos subadultos y adultos, así como en hembras y machos, en ambas temporadas. Los eritrocitos fueron las células sanguíneas más grandes y los linfocitos las más pequeñas. El conteo diferencial de leucocitos mostró que los linfocitos fueron los leucocitos más abundantes y los basófilos los menos numerosos. Los porcentajes de algunos leucocitos mostraron diferencia por época (no reproductiva y reproductiva) en machos subadultos y adultos (p < 0,05) y por talla (subadultos y adultos) en machos y hembras sólo en temporada no reproductiva (p < 0,05). Los leucocitos que tuvieron la mayor variación fueron linfocitos, heterófilos y eosinófilos. El conocer la morfología de las células sanguíneas y el conteo diferencial de leucocitos en individuos sanos de cocodrilo de Morelet criados en granja permitirá diagnosticar con precisión algunas enfermedades de individuos manejados en cautiverio y también de individuos silvestres.

Spectrum of Reactive Morphological Alterations in Leucocytes in HIV Patients.

Background: The earliest hematological manifestation of HIV infection can occur at the time of primary infection. Several peripheral blood abnormalities are known in HIV. However, not many studies have reported morphological changes in white blood cells in antiviral naïve patients and even fewer have compared them with HIV seropositive patients. Material and methods: Peripheral blood smears from 100 patients were studied. 50 of them were newly diagnosed HIV seropositive cases and 50 were HIV seronegative. A peripheral blood smear was made to study morphology of various white blood cells A written informed consent was taken. Statistical analysis of the data obtained was done. Results: Morphological abnormalities in the lymphocytes had been the most significant finding, which included nuclear lobulation, nuclear convolution and plasmacytoid and monocytoid features. Neutrophils also showed various morphological abnormalities. Most common were hypogranulation, hypersegmented nuclei and cytoplasmic vacuolations in descending order of frequency. Monocytes also revealed few morphological abnormalities including nuclear irregularities and cytoplasmic vacuolations. Conclusion: The observations from this study will serve as a guide to clinicians as treatment of these patients should include supplements to monitor and improve these changes.

The comparison of methods of the microscopic examination with Sternheimer-Malbin stain and UF-5000 analyzer for urine sediment / Эрүүл мэндийн лаборатори

Background@#Chronic kidney disease (CKD) is a global health problem. In Mongolia, urine is analyzed by methods of urine chemistry and urine sediment to diagnose kidney disease. The currently automated urine sediment analyzers have been widely used in clinical laboratories and are replacing traditional manual microscopic examination. Nonetheless, visual microscopic examination is still required in many cases. When chemical and sediment analyzers are used together, urine sediment could be confirmed under a microscope, if the results are inconsistent. Sternheimer-Malbin stain has contained a variety of dyes that help to distinguish particles (white blood cells, red blood cells, epithelial cells, casts, crystals, fatty drops, bacteria, yeast, trichomonas) in urine sediment, improve the differentiation between cell nuclei and cytoplasm, and provide more information about cell shape and image. </br> Therefore, the low-cost method that can be used on a daily basis.Although there are more than 4,500 laboratories in Mongolia that need to perform urinalysis, which is an important part of clinical laboratories, less than 10 percent of hospitals have fully automated sediment analyzers. For this reason, one of the most important issues in the clinical laboratories, the search for low-cost and useful methods for the analysis of urine sediments in order to provide access to services to the public. Our aim was the comparison of methods of the microscopic examination with Shternheimer-Malbin stain and fully automated UF-5000 analyzer for urine sediment. @*Methods@#There was a comparative study, people who served the Clinical Central Laboratory of Mongolia-Japan Hospital received permission to participate in this research. One hundred five fresh, first morning, clean catch mid-stream urine samples were collected in accordance with standard operating instructions for urinalysis, between November 2020 and May 2021. Sternheimer-Malbin (SM) staining and direct microscopy observation methods with Fuchs-Rosenthal counting chamber were used to red blood cells (RBC), white blood cells (WBC) and epithelial cells (EC) in urine samples. The agreements between the automated urine analyzer and microscopic methods were calculated using Cohen’s kappa (k) with 95% confidence intervals (CI).@*Results@#A total of 105 samples were collected and analysed in this study. The average age was 46.97±15.0and gender by 18% (n=19)were male and 82% (n=86) were female. </br> Compared to traditional manual methods and automated analyzer, the agreement within the same grade was 99/105 (94.3%) for erythrocytes, 96/105 (91.4%) for leukocytes, 92/105 (87.6%) for epithelial cells. And compared to Sternheimer-Malbin staining microscopy observation and automated analyzer, the agreement within the same grade was 98/105 (93.3%) for erythrocytes, 99/105 (94.3%) for leukocytes, 96/105 (91.4%) for epithelial cells. Agreement between traditional manual method and automated analyzer was higher than 85% and between Sternheimer-Malbin staining microscopy observation and automated analyzer was higher than 90%. The concordance between traditional manual method and automated analyzer was substantial (k=0.74, p<0.001; k=0.79, p<0.001) for RBC and EC, almost perfect (k=0.92, p<0.001) for WBC. Whereas the concordance between SternheimerMalbin staining microscopy observation and automated analyzer was substantial (k=0.70, p<0.001) for RBC, almost perfect (k=0.94, p<0.001; k=0.89, p<0.001) for WBC and EC. Comparison of Sysmex UF-5000 with microscopic particle counting methods resulted specificity was 98.9/100% for RBC, sensitivity was 97.7/95.3% and negative predictive value was 98.4/96.8% for WBC, sensitivity was 87.5/68.8% and negative predictive value was 97.8/94.7% for EC.@*Conclusion@#The Cohen’s k analysis result of comparisons between the SternheimerMalbin staining microscopic method and automated urine sediment analyzer showed significant almost perfect agreement (k=0.70-0.94, p<0.001). </br> The sensitivity and negative predictive value were high for both of WBC and EC were determined by Sternheimer-Malbin (SM) staining microscopy observation method. Results indicate the ability of a test to correctly identify those with the true positive and individual with a negative test result is truly negative better than comparison of Sysmex UF-5000 with traditional manual microscopic method assessment.

Effects of yacon flour associated with an energy restricted diet on intestinal permeability, fecal short chain fatty acids, oxidative stress and inflammation markers levels in adults with obesity or overweight: a randomized, double blind, placebo controlled clinical trial

ABSTRACT Objectives Yacon flour is rich in bioactive compounds (phenolic compounds and fructooligosaccharides (FOS)), and may therefore reduce the risk of diseases associated with excess body weight. However, its effect on fecal short chain fatty acids (SCFA), intestinal permeability, oxidative stress and inflammation markers has not been studied in adult humans with excess body weight. Thus, we evaluated the effect of the consumption of yacon flour on these variables. Materials and methods Twenty-six excess body weight (30.4 ± 2.4 kg/m2) adults (31.3 ± 8.5y) were randomized to one of two groups (yacon flour or control; n = 13) on a double blind clinical trial. Subjects received a breakfast drink containing or not yacon flour (25g) associated with an energy restricted diet, for six weeks. The flour chemical characterization, FOS and total phenolics contents were evaluated. Antioxidant capacity was evaluated in vitro and in vivo (plasma). Intestinal permeability, fecal SCFA, oxidative stress and inflammatory markers also were evaluated in vivo. Results Yacon flour was well tolerated. It presented an in vitro and in vivo antioxidant capacity, increased plasma total antioxidant capacity (ΔYAC: 49.16 (-4.20; 156.63)) and reduced protein carbonyl concentrations (ΔYAC: -0.98 (-1.54; -0.42)). A reduction in SCFAs was observed in both groups (Δacetic: -3.16 (-5.07; -0.95) vs. -1.05 (-2.65; 1.11); Δpropionic: -1.05 (-2.60;-0.38) vs. -0.41 (-2.08; 0.09); Δbutyric: -0.75 (-1.38; -0.04) vs. -0.28 (-0.98; 0.11), for YAC and CON, respectively). Other variables did not change. Conclusion The yacon flour increased the plasma antioxidant capacity, decreased oxidative stress and SCFAs in adults with obesity or overweight.

Detection of white blood cells in microscopic leucorrhea images based on deep active learning / 生物医学工程学杂志

The number of white blood cells in the leucorrhea microscopic image can indicate the severity of vaginal inflammation. At present, the detection of white blood cells in leucorrhea mainly relies on manual microscopy by medical experts, which is time-consuming, expensive and error-prone. In recent years, some studies have proposed to implement intelligent detection of leucorrhea white blood cells based on deep learning technology. However, such methods usually require manual labeling of a large number of samples as training sets, and the labeling cost is high. Therefore, this study proposes the use of deep active learning algorithms to achieve intelligent detection of white blood cells in leucorrhea microscopic images. In the active learning framework, a small number of labeled samples were firstly used as the basic training set, and a faster region convolutional neural network (Faster R-CNN) training detection model was performed. Then the most valuable samples were automatically selected for manual annotation, and the training set and the corresponding detection model were iteratively updated, which made the performance of the model continue to increase. The experimental results show that the deep active learning technology can obtain higher detection accuracy under less manual labeling samples, and the average precision of white blood cell detection could reach 90.6%, which meets the requirements of clinical routine examination.

Comparison of hematological parameters among newborns with meconium stained amniotic fluid and clear amniotic fluid

Background: Meconium stained amniotic fluid is an indirect marker of fetal hypoxia. Fetal hypoxia affects bone marrow and affects production of cell lines. Indirect marker of erythropoietin activity is nucleated red blood cells count. Aim of the study is to compare hematological parameter in newborn born with meconium stained liquor and clear amniotic fluid. Also, to determine cut off levels of nucleated RBC as marker of fetal hypoxia in meconium stained amniotic fluid(MSAF).Methods: The study was conducted over a period of 2 years from January 2012 to January 2014 in Department of Pediatrics, Sri Aurobindo medical college and hospital, Indore. One hundred newborns with meconium stained amniotic fluid (study group) and one hundred newborns with clear amniotic fluids (control group) were studied in this period. Cord blood samples were collected and hematological parameters were compared.Results: Hemoglobin % and WBC counts were seen in study group in comparison to control group, which is statistically significant (P<0.05). The reported NRBC/100 WBC between the two groups was statistically analyzed. The mean NRBC count in study group were 8.09'6.09 which was statistically higher than the corresponding values in control group 2.07'2.25 (P<0.05).Conclusions: Study concluded that the hemoglobin levels , WBC and NRBC counts in babies with meconium stained amniotic fluid is higher than those babies delivered with clear amniotic fluid and NRBC can be taken as a surrogate marker of hypoxia in a resource limited setting.

White blood cell count on admission as prognostic marker for assessment of severity of acute myocardial infarction

Background:High white blood cell/leucocyte counts were predicted as important biomarkers for future cardiovascular events in both healthy individuals and are having history myocardial infarction. The aim of the study was to assess the role of leucocytes as predictors of morbidity and mortality during the hospitalization of patients with acute myocardial infarction.Methods:This was a prospective study conducted on 79 patients with evolving STEMI attending the emergency department of Maharaja Yeshwant Rao Hospital, Indore during the period from November 2004 to July 2005. Blood total leucocyte count (TLC) was done in all the patients. All-cause mortality rate during the follow up period was defined as the primary end point of the study. Composite of death, reinfarction and heart failure till follow up day were defined as the secondary outcomes.Results:The mean age of the patients was 55.9±10.4 years. Male dominance was (86%) seen in the study. The mean TLC in the study population was 12345±4922/cumm. A total of 16 (20.2%) patients were died during 3 months of follow up. Statistically significant difference (p<0.001) was seen for characteristics such as age, risk index score,mean blood pressure heart rate and the Kilip class between survivors and non-survivors. The mean difference of TLC and mean CKMB was greater in non-survivors compared to survivors but the difference was not significant (p=0.177). Age, risk index, Kilip class, serum creatinine and baseline TLC, was found to affect the occurrence of the events significantly with a p value of less than 0.05. Conclusions: The findings conclude that the high blood leucocyte count was proved to be an important prognostic factorfor assessing the severity of acute myocardial infarction in study population

Antipuritive Effect of Aqueous Root Extracts of Moringa oliefera on Alcohol-induced Haematoxicity in Wistar Rats

Aim: The study is aimed at investigating the antinutritive effects of aqueous root extract of Moringa oleifera on haematological indices following sub-chronic consumption of alcohol in Wistar rats. Methods and Materials: Thirty (30) experimental rats weighing 100-120 g were randomly divided into 6 groups of 5 rats each. Group 1, the normal control group was given just rat feed and water, group 2, negative control was administered alcohol only (1.5 ml/kg body weight), rats in group 3, 4 and 5 received combined administration of alcohol 1.5 ml/kg body weight and 200, 400 and 600 mg/kg body weight of aqueous root extract of Moringa oleifera respectively, group 6 rats were administered 250 mg/body weight of extract only. At the end of fourteen days (14) the experimental rats were then sacrificed, and blood was collected for haematological analysis. Results: The result obtained shows a dose-dependent response in almost all the parameters, white blood cell (WBC) count increases significantly(P<0.05) with 600 mg/kg while dose 200 mg/kg and 400 mg/g shows no significant change. Red blood cells (RBC) decreases non-significantly (P<0.05) with increased amount of aqueous Moringa root extract. Likewise, there was also a dose-dependent decrease in the haematological count and more noticeable with 200 mg/kg dose. It was also observed that mean corpuscular haemoglobin concentration (MCHC) and mean corpuscular volume (MCV) increases in all the treatment groups with significant observed in 400 mg/kg and 600 mg/kg. The increase in alcohol can bring about suppression of the blood cells production, enhance if there is reduction in the red blood cells, it, therefore, implies that the will be reduction in the oxygen-carrying capacity of the red blood cells, that would be carried to the tissues as well as the level of carbon dioxide returned to the lungs. Also, the PCV is involved in the transport of oxygen and absorption of the nutrient. Therefore, increase in PCV, shows a better transportation and thus results in an increase in both primary and secondary polycythemias. Conclusion: This research work shows that the plant extract contains some bioactive component or phytochemical constituents that are capable of ameliorating the toxicity effect of alcohol on animal models.

Biochemical and Hematological Impact of Hepatitis C Virus (HCV) on Human Immunodeficiency Virus (HIV) Infected Persons on Antiretroviral Drugs (ARDs) in Nigeria

Introduction: Biochemical and hematological abnormalities are among most common clinico-pathological manifestations of HIV/AIDS infected persons on antiretroviral drugs (ARDs). Hepatitis C Virus (HCV) infection are known to influence progression and management of HIV infection. Data are limited regarding the impact of ARDs on HIV/HCV co-infected persons in Nigeria. Hence, this study evaluated the biochemical and hematological impact of HCV on prognosis of HIV persons taking ARDs. Materials and Methods: 2,322 HIV infected persons were screened for HCV. One hundred and nine were co-infected with HCV; and were cross-sectional monitored on ARDs for fifteen months at hospitals in North Central Nigeria for changes in clinical profiles. The determination of Alanine aminotransferase (ALT), Aspartate transaminase (AST), Packed cell volume (PCV) and White blood cells count (WBC) estimations were reviewed every 3 months for each of the person using Reflotron plus machine and hematological analyzer according to the manufacturer抯 instructions. Results: The results showed an increase in both HIV mono-infected and co-infected patients, with raised in AST from 18.46�73 to 34.32�6053U/l, ALT from 19.37�6804 to 34.87�5637U/l, PCV from 34.20�2998 to 34.89�4895% and WBC from 3.50x109�0816 to 6.67x109�1204 cells/L and AST from 17.35�1542 to 34.49�0981U/l, ALT from 17.67�1412 to 34.80�15U/l, PCV from 36.74�2902 to 38.37�4399% and WBC from 3.90x109�0251 to 6.19x109�0178 cells/L. Conclusion: It was found that PCV and WBC count values were positively affected despite HCV replication and AST and ALT enzyme levels for both HIV-mono and co-infected persons were slightly elevated. Therefore, efforts addressing viral hepatitis co-infections at the early stage of ARDs initiation under qualified clinician should be of paramount important.

Promotion of Ziyuglycoside I on white blood cells by autophagy pathway / 中草药

Objective: To study the mechanism of ziyuglycoside I (ZgI) increasing the number of white blood cells (WBC) in peripheral blood. Methods: KM mice were randomly divided into control group, model group, 3-methyladenosine (3-MA) group, ZgI group (20 mg/kg), and ZgI (20 mg/kg)+3-MA group. On the first day of experiment, myelosuppression mice were induced by ip cyclophosphamide of 120 mg/kg and were continuously gavaged with ZgI for 6 d. On the 6th day, the number of WBC and granulocytes were determined. The degree of hematopoietic stem cells (HSCs) autophagy was observed by transmission electron microscopy and immunofluorescence microscopy. The apoptosis rate of HSCs was determined by flow cytometry, and the expression of Atg5, Atg7, and Beclin-1 proteins were detected by Western blotting. Results: Compared with the model group and 3-methyladenine group, ZgI significantly increased the numbers of leukocyte and granulocytes (P < 0.05), it also significantly stimulated the autophagy of HSCs. Meanwhile, ZgI significantly up-regulated the Atg5, Atg7, and Beclin-1 (P < 0.01) proteins expression in HSCs. Conclusion: The results suggested that ZgI was an efficient autophagic activator, and the mechanism of increasing WBC might be related to the promotion of HSCs autophagy of myelosuppression mice.

Clinical characteristics of 130 bacterial pneumonia children and the changes of the levels of serum WBC, CRP and PCT / 中国基层医药

Objective To observe the clinical characteristics of bacterial pneumonia children,and the changes of the serum levels of white blood cells(WBC),C-reactive protein(CRP) and procalcitonin(PCT) before and after anti-bacterial therapy,and to explore the predictive value in early diagnosis and therapy.Methods 130 bacterial pneumonia children were enrolled prospectively as pneumonia group.The clinical data were collected and the serum CRP,PCT and WBC were detected before anti-bacterial therapy (within 24h after admission) and after anti-bacterial therapy (the seventh day after admission).34 healthy children were enrolled as control group.The general clinical characteristics of the children in the pneumonia group were observed.The levels of serum CRP,PCT and WBC between the pneumonia group and the control group were compared.The levels of serum CRP,PCT and WBC before and after anti-bacterial therapy in the bacterial pneumonia children were compared.The clinical value of PCT,CRP and WBC in early predicting bacterial pneumonia was identified.Results Compared with the control group,the sex and age of the bacterial pneumonia children demonstrated no statistically significant differences (t =1.012,P =0.395;x2 =0.003,P =0.959).The mean course of the disease before admission was (5.34 ± 1.27) d,with mean temperature of (38.27 ± 0.96) ℃,and hospital days of (8.92 ± 3.93) d.35 cases were cured,and 95 cases were improved,with no death.The serum levels of CRP,PCT and WBC in pneumonia children on admission were (12.24 ±6.35) mg/L,(0.18 ± 0.15) ng/mL and (14.25 ± 7.59) 109/L,respectively,which were higher than those of the control group,the differences were statistically significant (t =4.650,5.867,2.548,all P ＜ 0.05).The serum levels of CRP,PCT and WBC in pneumonia children before anti-bacterial therapy were higher than after bacterial therapy,showed statistically significant differences(t =8.165,7.232,5.112,all P ＜ 0.05).The area under the curve (AUC)of the PCT,CRP and WBC in early predicting bacterial pneumonia were 0.928,0.834 and 0.718 respectively by the relative operating characteristic (ROC) curve analysis (P ＜ 0.05).The sensitivity and specificity of PCT in predicting bacterial pneumonia were higher than CRP and WBC.Conclusion The statistics efficacy of PCT in early predicting children bacterial infection was obviously higher than CRP and PCT.The combined detection of CRP,PCT and WBC was benefit to improve the diagnostic sensitivity and specificity of children with bacterial pneumonia.

Comparative leukocyte morphometric analysis between endemic Anurans from Brazil and the invasive species Lithobates catesbeianus / Análise morfométrica comparada entre Anuros endêmicos do Brasil e a espécie invasora Lithobates catesbeianus

Amphibians are potentially reliable and efficient bioindicators. Existing anuran white blood cell morphology studies are limited, with only a few morphometric studies available. We employed morphometric techniques to characterize leukocytes of selected Neotropical anurans from Brazil and compare our findings with the exotic American Bullfrog (Lithobates catesbeianus), genus Ranidae. We compared blood smears of 28 specimens from six different genera (Hyla, Phyllomedusa, Hypsiboas, Scinax, Physalaemus, and Proceratophrys) with samples from L. catesbeianus. Leukocyte average diameter was calculated by an image analysis software. One-way analyses of variance and Bonferroni tests were used on statistical analyses. Lymphocytes, neutrophils, eosinophils, and basophils were significantly smaller than the reference ranges reported for other amphibian genera, including Lithobathes, whereas monocyte diameters did not differ significantly between genera. This is the first study to evaluate leukocyte morphometrics of Brazilian anuran species. Our findings suggest that geographical separation could possibly influence leukocyte morphometry.(AU)

Anfíbios são indicadores ambientais potencialmente confiáveis e eficientes. Estudos referentes à morfologia de leucócitos de anuros são limitados, com poucos estudos morfométricos disponíveis em literatura. O presente estudo empregou técnicas morfométricas para caracterizar leucócitos de anuros Neotropicais brasileiros selecionados e compará-los com a espécie exótica rã-touro (Lithobates catesbeianus), família Ranidae. Esfregaços sanguíneos de 28 espécimes pertencentes a seis gêneros diferentes (Hyla, Phyllomedusa, Hypsiboas, Scinax, Physalaemus e Proceratophrys) foram comparados com amostras de esfregaços de L. catesbeianus. A média do diâmetro dos leucócitos foi calculada por um software de análise de imagens. One-way e teste de Bonferroni foram utilizados para avaliação estatística. Linfócitos, neutrófilos, eosinófilos e basófilos mostraram-se significativamente menores que os valores de referência reportados em outros gêneros de anfíbios, incluindo Lithobathes; por outro lado, a média do diâmetro dos monócitos não demonstrou variação significativa entre os gêneros. Esse é o primeiro estudo de avaliação morfométrica de leucócitos em espécies de anuros brasileiros. Nossos resultados sugerem que a separação geográfica possivelmente influencia a morfometria leucocitária.(AU)
