Abstract A correlation between prior exposure to Mycoplasma pneumoniae (IgG positive) and better clinical response to COVID-19 was elusive. In the present study, a retrospective review of 133 COVID-19 infected patients treated at Wuhan Union Hospital from Feb 1 to Mar 20 was carried out. Our data showed that COVID-19 infected patients with mycoplasma lgG positivity had a higher lymphocyte count and percentage (p = 0.026, p = 0.017), monocyte count and percentage (p = 0.028, p = 0.006) and eosinophil count and percentage (p = 0.039, p = 0.007), and a lower neutrophil count and percentage (p = 0.044, p = 0.006) than COVID-19 infected patients without mycoplasma lgG. Furthermore, requirement and use of a nasal catheter or oxygen mask was significantly lower in COVID-19 infected patients with mycoplasma lgG positivity (p = 0.029). Our findings indicate that mycoplasma IgG positivity is a potential protective factor for COVID-19.

AbstractBackgroundA correlation between prior exposure to Mycoplasma pneumoniae (IgG positive) and better clinical response to COVID-19 was elusive.MethodsA retrospective review of all COVID-19 infected patients treated at Wuhan Union Hospital from Feb 1 to Mar 20 was carried out. Continuous variables were described as mean, median, and interquartile range (IQR), while categorical variables were compared by X2 test or Fisher’s exact test between COVID-19 infected patients with mycoplasma lgG (-) and mycoplasma lgG (+).ResultsStatistically significant differences were shown in terms of laboratory test results. COVID-19 infected patients with mycoplasma lgG positivity had a higher lymphocyte count and percentage (p=0.026, p=0.017), monocyte count and percentage (p=0.028, p=0.006) and eosinophil count and percentage (p=0.039, p=0.007), and a lower neutrophil count and percentage (p=0.044, p=0.006) than COVID-19 infected patients without mycoplasma lgG. Other routine blood tests, including coagulation tests, blood biochemistry and infection-related biomarkers did not significantly differ except for thrombin time (p=0.001) and lactate dehydrogenase (p=0.008). Furthermore, requirement and use of a nasal catheter or oxygen mask was significantly lower in COVID-19 infected patients with mycoplasma lgG positivity (p=0.029).ConclusionsOur findings indicate that mycoplasma IgG positivity is a potential protective factor for SARS-CoV-2 infection.

Coronavirus is affecting millions of people world-wide. Coronavirus disease 2019 (COVID-19) is declared a pandemic by WHO. Severe acute respiratory syndrome corona virus 2(SARS-CoV-2) is the causative agent. The clinical presentations of SARS-CoV-2 infection range from febrile illness to pneumonia, ARDS and multi organ failures. Increasing scientific evidences have shown that abnormalities in routine laboratory test, particularly haematological parameters influence the outcome of the disease. Here variations in WBC profile in several clinical forms of COVID-19 patients are observed, The clinical course of the disease may change with haematological parameters such as lower total count of WBC, lymphocyte, higher neutrophil count, eosinophil count etc. By investigating haematological parameters of different clinical stage of RT-PCR positive 100 COVID-19 patients, statistically significant association (p value 0.001) of lymphocyte count with disease severity was found. It is also found that higher level of total count WBC, neutrophil count in severe group in comparison to mild and moderate groups but failed to reach any statistical significance. Moreover total count WBC and neutrophil count showed positive correlations but lymphocyte count, eosinophil count and monocyte count showed negative correlation with severity of disease. So, complete analysis of the haematological parameters will be very much helpful for early detection of complications & better control of the disease.

Background: COVID-19 is an ongoing pandemic caused by virus SARS-CoV-2. Many studies worldwide have documented hematological alterations in COVID-19. The present study also aimed to assess the CBC parameters in COVID-19 patients. Material And Methods: It was an observational study conducted in the Department of Pathology, Govt. Medical College, Jammu. COVID-19 patients admitted in the hospital were included in the study. Demographic details and clinical status were noted. EDTA anticoagulated blood samples received were processed on automated 5-part hematology analyzer for CBC. Various parameters obtained were evaluated and also compared with clinical severity of the patients. Results were tabulated and analysed statistically. Results: The study included 304 hospitalized COVID-19 patients. Males were 219 (72%) and females were 85 (28%). Median 6 age of patients was 55 years. Mean hemoglobin concentration was 12.05 g/dl (SD-1.93), mean RBC count was 4.21x10 /µL (SD3 3 0.69). Mean WBC count was 9.66x10 /µL (SD-4.80), mean absolute neutrophil count was 7.87x10 /µL (SD-4.63), mean absolute 3 3 lymphocyte count was 1.22x10 /µL (SD-0.77), mean absolute monocyte count was 0.52x10 /µL (SD-0.29), mean absolute 3 eosinophil count was 0.04 x10 /µL(SD-0.10). Mean NLR was 10.03 (SD-12.27), mean LMR was 2.84 (SD-2.02), mean PLR was 3 220.16 (SD-208.46). Mean platelet count was 187x10 /µL (SD-97.78). Patients with severe disease show signicantly raised WBC count and absolute neutrophil count, signicantly decreased absolute lymphocyte count, signicantly higher eosinophil count, NLR, PLR and signicantly decreased LMR with no signicant difference in absolute monocyte count and platelet count. Conclusion: Routine monitoring of CBC parameters in COVID – 19 patients during the course of illness is a simple, rapid means to assess disease severity and progression in these patients.

Introduction: The aim of this study was to evaluate how altitude difference affects complete blood count (CBC) in patients with stable Chronic Obstructive Pulmonary Disease (COPD). Study Design: Cross-sectional study. Setting: Department of Pulmonology, Kars Harakani State Hospital (Group 1) and Samsun Chest Diseases and Thoracic Surgery Hospital (Group 2), Turkey. Period: Six months i.e. from March to September 2018. Material and Methods: A total of 400 patients (200 female, 200 male) with stable COPD were included. For each group, 100 female and 100 male patients were randomly selected from hospitals. Age, BMI (kg/m2), comorbidity, smoking status, CBC were evaluated. Hemoglobin, hematocrit, WBC, MPV, platelet, lymphocyte count and percentage, platelet/lymphocyte rate (PLR), neutrophil count and percentage, neutrophil /lymphocyte rate (NLR), eosinophil count and percentage, PDW, PCT were recorded. Results: Patients living at high altitude were significantly older, had lower weight and had lower FEV1 levels. COPD stages of Group 1 patients were more severe (p<0.001). There were no moderate COPD patients in this group and the patients had fewer comorbidities (43%). Hemoglobin, hematocrit, MPV, WBC, neutrophil count and percentage, NLR and PLR were significantly higher in Group 1 (p<0.001). PDW, PCT, lymphocyte count and percentage, eosinophil count and percentage were significantly higher in Group 2 patients (p<0.001). Conclusion: Hemoglobin, hematocrit, MPV, WBC, neutrophil count and percentage, NLR and PLR were higher in patients living at high altitude. PDW, PCT, lymphocyte count and percentage, eosinophil count and percentage were significantly higher in patients living at low altitude.

371 Background: Inflammation plays a key role in the pathophysiology of many diseases, including cancer. Systemic inflammatory factors have been validated as indicators of ongoing systemic inflammation that could be predictive markers of poor prognosis for oncological outcomes. However, it is unknown the prognostic impact of systemic inflammation markers in patients with GEP-NETs treated with PRRT. Methods: We conducted an observational, retrospective, multicentric study of 40 patients with GEP-NET treated with PRRT belonging to GGNET (Galician Research Group on Neuroendocrine Tumors) network at Nuclear Medicine Department of Santiago de Compostela University Hospital (Spain). The systemic inflammatory markers were calculated as follows: NLR = neutrophil count/lymphocyte count, PLR = platelet count/lymphocyte count, MLR= monocyte count/lymphocyte count, ALB= albumin levels and dNLR = neutrophil count/ (leucocytes count – neutrophils count). For the calculation of the different ratios, baseline analysis and after the second dose were used. The cut-off values were determined as the median of each values, correlating them with progression-free survival (PFS). Results: Data from 40 patients (pts) treated between 2016 and 2020 were recorded. Median age was 63.5 years (range 41-85) and 55% were male. Baseline ECOG PS 0/1/2 was 15 (37.5%)/16 (40%)/9 (22.5%). Tumor location was intestinal 26 pts (65%), pancreas 11 pts (27.5%) and unknown origin 3 pts (7.5%). 15 pts (37.5%) were functioning. Tumor grade G1/G2/G3 were 17 pts (42.5%)/ 20 pts (50%)/ 3 pts (7.5%), and Ki 67 <2/3-20/>20%/unknown were 11 pts (27.5%)/ 21 pts (52.5%)/ 3 pts (7.5%)/ 5 pts (12.5%), respectively. The most frequent site of metastasis was liver 32 pts (80%), lymph nodes 19 pts (47.5%), peritoneum 11 pts (27.5%) and bone 10 pts (25%). Surgery: 22 pts (55%) primary tumor surgery and 8 pts (20%) metastasectomy. Previous systemic treatments included somatostatin analogs (SSA) 40 pts (100%), everolimus 26 pts (65%) and sunitnib 11 pts (27.5%), others 7 pts (17.5%). The baseline cutoff-values for NLR was 2.61, for PLR 110.14, for MLR 0.31, for ALB 4.2. and for dNLR 1.71. The cutoff-values after the 2nd dose for NLR was 2.3, for PLR 2.15, for MLR 0.3, for ALB 4.2 and for dNLR 1.48. With a median follow up of 21 months, 14 pts (35%) had died. Median PFS was 27.2 m (95% CI 16.0-38.4m) and OS was not reached (NR). Pts with baseline higher NLR (>2.61 vs. <2.61) had a significantly lower PFS: 15.8 m vs. NR (HR 0.181; 95% CI 0.051-0.638, p=0.03), which was also true for pts with elevated dNLR (>1.71 vs. <1.71): PFS 15.8 m vs. NR (HR 0.174; 0.049-0.614, p=0.03). Baseline PLR, ALB, MLR and NLR, PLR, ALB, dNLR and MLR values after the 2nd dose was not statistically significant for PFS. Conclusions: We have identified that baseline NLR and dNRL are significant predictive factors in patients with GEP-NETs treated with PRRT.

Kasa is one of the commonest complaints in day to day life and clinical manifestation affecting Pranavaha Srotas. Among the five major types of Kasa mentioned by Acharyas, Vata, Pitta & Kaphaja Kasa have distinct and significant clinical features and Samprapti. Early intervention is necessary in case of Kasa as it is a potential Nidanarthakara Vyadhi (disease having tendency to produce secondary diseases) to produce Kshaya. This observational study involving 150 subjects of age group 16 to 60 was carried out to assess the utility of hematological investigations (T.C, D.C, AEC, and ESR) to diagnose Vata, Pitta and Kaphaja Kasa respectively. Assessment of type of Kasa was done by scoring system of classical symptoms and changes in laboratory parameters were noted for each. Results are drawn based on Statistical evaluation of each type of Kasa with respect to each of the hematological investigation involved in the study. Investigations like neutrophil count, absolute eosinophil count and lymphocyte count have shown significant association with respect to Vataja, Pittaja and Kaphaja Kasa.

Abstract Purpose To investigate clinical characteristic and prognostic factors for chronic myelomonocytic leukemia (CMML). Methods Retrospective cohort study was used in the study. Information for CMML patients was collected, including symptoms, CBC, results of bone marrow aspire and pathology, cytogenetic. All patients were followed up regularly. Analysis of survival and prognostic factors was performed by Kaplan-Merier cure, log rank test and Cox regression model. Results Forty-one cases were diagnosed as CMML, including 27 male and 14 female patients. Median WBC was 13.7× 109/L. Five patients had leukocytopenia(1.92- 3.46×109/L). Median monocyte count in the peripheral blood was 2.13×109/L, but lower monocyte count (&lt;1×109/L) occurred in 8 patients. All patients presented with bone marrow dysplasia, and most showed hyperplasia, except 3 cases. Abnormal chromosome was detected in 34% cases. Median survival time was 20 months, and there were no difference of survival duration between CMML-1 and CMML-2. Univariate analysis showed that age (&gt; 60 yrs), neutrophil count (&lt;2.0′109/L), lymphocyte count (&lt;1.0′109/L), mature monocyte count (35′109/L) and anemia (Hb&lt; 60g/L) were associated with poor prognosis for CMML. There was no statistical significance in LDH, gender, abnormal chromosome for survival time. Only lymphocyte count and neutrophil count in peripheral blood were independent prognostic factor for CMML after Multivariate analysis. Conclusion CMML mainly occur in elderly patients. Although most patients have leukocytosis and monocytosis at diagnosis, few case shows leucopenia and monocytopenia. Median survival time for CMML is 20 months. Age, neutrophil, lymphocyte and monocyte count, severe anemia are related to CMML prognosis. Neutropenia and lymphopenia in peripheral blood are independent prognostic factor for CMML.

This study was carried out on clinical cases of retained fetal membranes in crossbred cows presented at College Clinics and College dairy farm and from Villages in and around Mhow. The blood samples were collected from jugular vein just before 12 hr. postpartum and on 7th day postpartum. Haematological profile revealed that the mean values of haemoglobin, neutrophil and monocyte count after 12 hrs and 7th day postpartum were significantly lower and lymphocyte count was significantly higher in RFM cows (n=18) than normally calved cows (n=6). The differences in mean TLC, eosinophil and basophil counts were non-significant at 12 hrs postpartum, however on 7th day postpartum the TLC and eosinophil count were significantly higher and basophil count was non-significantly different in RFM cows than the normally calved cows.
