The acute-phase inflammatory response in the peripheral bloodstream can be an expression of transient cerebral ischaemia in idiopathic sudden deafness. For this, a neurological and otorhinolaryngological examination of each patient, performing tests on audiometry, and tympanometry, haemogram, and cranial magnetic resonance were performed. The acute-phase inflammatory response manifests as an increased neutrophil/lymphocyte ratio that is detected 48–72 hours after the appearance of sudden deafness. This study shows that there is an acute-phase response in the peripheral bloodstream with an increased neutrophil/lymphocyte ratio as an expression of an inflammatory process that can be caused by transient cerebral ischaemia in sudden deafness. In addition, the increased neutrophil/lymphocyte ratio can rule out a viral origin of sudden deafness, since a viral infection lowers the neutrophil count and increases the lymphocyte count, thus reducing the neutrophil/lymphocyte ratio. These findings aid in understanding the pathogenic mechanisms involved in sudden deafness and offer better treatment to the patient.

Background: Canine Leishmaniasis (CanL) is a multisystemic and chronic inflammatory disease characterized by nonspecific clinical manifestations. In CanL, inflammatory cells and chemical mediators released in response to the parasite play a role in disease development and progression. Alterations on hematological parameters have been documented in CanL. These changes can also be assessed in relation to systemic inflammation caused by this disease. The circulating leukocyte counting, such as neutrophils, as well as the albumin level, are considered direct indicators of an inflammatory host environment. Several studies point to the use of biomarkers on the assistance in diagnosis and prognosis of several canine pathologies. The present study investigated the Neutrophils to Lymphocyte Ratio (NLR), Albumin to Globulin Ratio (AGR), and Neutrophils to Albumin Ratio (NAR) on systemic inflammatory response induced by Canine Leishmaniasis (CanL).Materials, Methods & Results: For this purpose, adult dogs with confirmed diagnosis to CanL were divided into symptomatic (SD, n = 33) and asymptomatic (AD, n = 20) dogs for L. infantum and control dogs (CD, n = 20). Routine hematological and biochemical parameters were determined in blood samples using a veterinary automatic hematology and biochemical analyzers. Asymptomatic dogs (AD) had a higher number of white blood cells and neutrophils (16.48 ± 4.93; 13.41 ± 3.60, respectively) in relation to symptomatic dogs (SD) (13.54 ± 5.13; 10.42± 3.69, respectively) (P = 0.015 and P < 0.0001, respectively). Neutrophils to Lymphocyte Ratio (NLR) was higher in dogs with leishmaniasis (9.45 ± 3.76) than in healthy dogs (3.39 ± 1.19) (P < 0.0001). Serum total proteins (STP) and globulins increased in CanL, while albumin and AGR decreased in CanL, when compared to CD and references values to canine species. Neutrophils to Albumin Ratio (NAR) was higher in AD and SD (5.02 ± 1.14; 4.79 ± 1.07, respectively) when compared to CD (2.36 ± 0.55) (P < 0.0001). Discussion: As reported in scientific researches, dogs with Leishmaniasis present alterations in circulating cell counts. Based on these data, we decided to expand this information using the NLR as a parameter in an attempt to better clarify the changes in these cells in CanL. We observed that NLR was increased on CanL in relation to healthy dogs, which could be a consequence of relative neutrophilia rather than lymphopenia. Neutrophils to Lymphocyte Ratio (NLR) is a biomarker that conveys information about inflammatory conditions. An elevated NLR can reflect an upregulated innate immune response, since neutrophils are effector cells of innate immunity and are involved in several acute and chronic inflammatory processes. Albumin is an acute phase protein that is considered an immune-inflammatory biomarker, which can be found reduced systemically in progressive inflammatory response. Serum total proteins (STP) and globulins were increased in CanL. These data are already well documented in CanL, which serum globulins are mainly associated with the increase of acute phase proteins, cytokines, and increase of specific antibodies to Leishmaniainfantum. Our results showed neutrophilia with hypoalbuminemia in CanL. So, in an attempt to assess the relationship of these two available markers, we used NAR calculation in order to evaluate the changes induced by CanL. In this study NAR was higher in CanL when compared to control dogs. Thus, our data indicate that NLR and NAR could be used as biomarkers in veterinary medical clinics in order to assess inflammatory profile in CanL, mainly in asymptomatic dogs. These parameters obtained from routine blood tests might be useful as cost-effective, easily accessible and helpful markers in order to distinguish the inflammatory response intensity in CanL.

Introduction: Systemic inflammatory response evoked by cardiac surgery involving a cardio-pulmonary bypass (CPB) in combination of surgical trauma, ischemia/reperfusion injury, hypothermia, and endotoxin release contributed to the postoperative morbidity and mortality. This study aimed to explore the potential of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) as novel markers to evaluate and predict the adverse clinical outcomes after longer CPB time in cardiac surgery. Methods: Patients who underwent cardiac surgery with or without CPB were allocated into two groups, CPB group (n=11) and N-CPB group (n=21). The time course of NLR, PLR, SII, and C-reactive protein (CPR) were analyzed at preoperative day 1 and postoperative day 1, 3, and 7. The baseline and postoperative parameters, the ICU and hospital stay were recorded. Results: There were no differences of baseline parameters between groups. The level of NLR, PLR, SII, and CPR at postoperative day 1 was higher than that in the preoperative day 1 in both groups (p < 0.01). The level of NLR, SII and CPR at postoperative day 3 was higher than that in the preoperative day 1 in both groups (p < 0.05). The NLR and SII at postoperative day 3 were higher in CPB group than that in N-CPB group (p < 0.05). The ICU and hospital stay was longer in CPB group than N-CPB group (p < 0.05). Conclusions: The longer duration of CPB time induced higher systemic inflammatory response characterized by higher level of NLR, PLR and SII. The SII predicted the poor outcome after longer CPB. The peak of systemic inflammatory response occurred on the third day after cardiac surgery.

Abstract Introduction The host systemic inflammatory response (SIR) is prognostic in a wide variety of solid tumours, with a greater degree of inflammation being associated with a worse clinical outcome. Neutrophil Lymphocyte Ratio (NLR) is an established way to measure SIR in vivo. We aimed to establish whether preoperative NLR correlates with infective complications in patients undergoing colorectal cancer (CRC) resection. Methods Data was extracted retrospectively for all CRC resections over a 2 year period (2016-2018) at a single district general hospital. NLR was measured for each patient from bloods at the time of pre-operative assessment. Post-operative complications were recorded using the Clavien-Dindo classification and subsequently classified as infective and non-infective. A Two-tailed Mann-Whitney U test was used to evaluate the data from an online resource. Results Of the 131 patients, 49 had complications of which 20 were infective. Of total complications 58% were male and 35% were aged 75 years or older. Current or ex-smokers constituted 43% and 41 of the total patients had a BMI &gt;30 kg/m2. Pre-assessment mean NLR was 2.3 in those without complications and 4.7 in those with any complication. A mean NLR of 5.4 was present in those with infective complications, p-value 0.026. Conclusion This study found that a raised NLR was present preoperatively in those who developed infective complications following CRC resection. This is a simple, readily available and cost-effective method of identifying patients at risk of complication. This ultimately may be useful in highlighting patients who would benefit from enhanced pre-operative optimisation. Further research to validate these findings in larger studies would seem warranted.

Background: Canine atopic dermatitis (CAD) is a chronic and inflammatory disease present in veterinary dermatological practice. The inflammation in CAD is triggered by environmental allergens and skin microorganisms, which are responsible for the worsening of cutaneous lesions. This continuous activation of skin inflammatory process can induce the production of free radicals that also contribute to cellular damage and ultimately leads to changes in blood parameters in dogs with CAD. Although there are reports of inflammatory parameters in CAD, there are a lack of studies correlating skin lesions, blood leukocytes and oxidative stress. Based on that,this study aimed to evaluate the integumentary and systemic inflammatory response in dogs with atopic dermatitis. Materials, Methods & Results: Dogs with confirmed diagnosis of canine atopic dermatitis (n = 10) were divided in two groups according to CADESI-IV: AI, with CADESI between 0-10, AII, with CADESI between 10-34, and control group (n = 5). Blood-biochemical and histological analysis were performed to access systemic and cutaneous inflammatory response. AII group tended to higher neutrophil and eosinophil counts, as well as neutrophil/lymphocyte ratio (NLR) when compared to AI. The albumin was lower in AII compared to AI and control (P < 0.05), while total bilirubin and malondialdehyde (MDA) did not differ between groups. NLR (r = 0.64 and P = 0.04) and MDA (r = 0.54 and P = 0.1) were positively correlated with CADESI, while albumin was negatively correlated with CADESI (r = -0.79 and P = 0.005). Histopathological analysis revealed a larger number of neutrophils, macrophages and mast cells in AI and AII than in control group (P < 0.05). Discussion: In this study it was possible to evaluate the systemic and cutaneous leukocyte dynamics in CAD. Skin inflammation induces the production of chemotactic molecules contribute to neutrophil outflow from blood vessel toward the affected tissue, which can be visualized as perivascular inflammatory infiltrate and exocytosis. At systemic level, there was a tendency to increase in total leukocytes and circulating neutrophil count in group AII, as well as in neutrophil/lymphocyte ratio (NLR), when compared to AI. The NLR is a widely available and inexpensive laboratory biomarker that quantifies systemic inflammation, being used in human medicine to evaluate prognosis in different types of cancer. In our study, dogs in AII group showed an increased NLR compared to AI and control, which demonstrates the influence of skin injury in systemic parameters. Furthermore, AII group is composed of dogs with greater lesion state, which reflects in higher NLR values. Since this disease is known by its chronicity and may remain stable for years, NLR may be a novel biomarker to evaluate acute exacerbation in CAD and could potentially explain why some patients have longer crisis duration and frequent flares. The maintenance of the inflammatory state also induces the production of oxidizing substances, which possibly exceed the total antioxidant capacity, generating a situation of oxidative stress, which can result in damage to membrane lipids and release of their products. MDA is reliable and is the most commonly used marker of the overall lipid peroxidation level and the presence of oxidative stress. This result may be related with the antioxidant system, such as albumin and bilirubin, which was able to promote an efficient control of oxidant substances. In conclusion, the presented data demonstrated an inflammatory process progression as well as introduced NLR as a potential marker of disease exacerbation in CAD.

Introduction: Assessment of systemic inflammatory response forms the basis of several scoring systems that attempt to prognosticate patients with periampullary pancreatic carcinoma (PPC). We assessed the validity of three of these scoring systems for patients’ prognosis following intervention for PPC: Glasgow prognostic score (GPS) and its modified version (mGPS), platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR).Methods: EMBASE and MEDLINE databases were searched for all published studies until September 2018 using comprehensive text word and MeSH terms. Meta-analysis of observational studies in epidemiology guidelines was followed. All identified studies were analysed and relevant studies were included in the review.Results: Three studies which assessed the role of GPS, four studies that evaluated the use of NLR and three that assessed the role of PLR in patients with PPC were identified. None of these studies demonstrated any value in the pre-operative assessment of patients with PPC. The limited number of studies available precluded further statistical analysis.Conclusions: Based on available evidence, GPS, NLR and PLR do not appear to be useful scoring systems to predict prognosis of patients with PPC. Larger studies are warranted before the application of inflammatory scoring systems could be recommended in patients with PPC.Key words: Periampullary cancer, Glasgow prognostic score, modified Glasgow prognostic score, platelet-lymphocyte ratio, neutrophil-lymphocyte ratio

Introduction: The COVID-19 infection is caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infection, which was first reported in Hubei, Wuhan province, China, in December 2019. There is a concern that immunocompromised patients are at greater risk of morbidity and mortality due to COVID-19 infection, although there is limited data on these patients. Here, we present an evolution of a series of cases of patients with COVID-19 in our service. Patients and methods: This is a retrospective cohort study conducted at the Hospital Universitário Walter Cantídio in Fortaleza-CE, Brazil. All patients hospitalized due to COVID-19 were screened for a history of organ or tissue transplantation, with a total number of 77 patients. Only patients confirmed for COVID-19 were included in the study. The inflammatory response and initial laboratory results, as well as the CALL score, were compared to a cohort of patients with COVID-19 not transplanted at the same time in our clinical ward or intensive care unit (ICU). The clinical course and clinical findings recorded during treatment were extracted from the electronic medical record. A bilateral P <0.05 (5%) was considered significant. Results: The total number of hospitalizations until July 24, 2020 for confirmed cases of COVID-19 was 77 patients. Of the total, 33 (42%) patients needed ICU. Most patients were male (61%). The median age was 62 [95% CI: 54-63] years, 31 (37%) had a previous diagnosis of hypertension, 24 (28%) of type 2 diabetes mellitus (DM-2). The total lethality of our service was 22%. The CALL score of patients admitted to the clinical ward and in the ICU was analyzed, with a higher average observed in the patients admitted in ICU, the average was 9.34 in the patients admitted in the clinical ward and 10.9 in the patients who required ICU. (p = 0.003) . The effect of neutrophil/lymphocyte ratio(NLR) at admission on the need of ICU care was analyzed by ROC curve and AUC and was found to be significant (AUC: 0.708, p = 0.002, 95% CI = 0.593 to 0.823). The number of transplant recipients in our service was 17 patients. The mean age was 56 years and the median was 55 years [95% CI: 45-65 years]. Of this subgroup, 6 patients (35%) required ICU, with no statistical difference when compared to non- transplanted patients (p = 0.443), and only 3 evolved to death (17%), also without statistical difference when compared to the subgroup of non-transplanted patients (p = 0.484). When compared to the sample of non-transplanted patients, lower values were found of the White Blood cells count, neutrophils and ferritin. However, despite lower values of fibrinogen, D-dimer, C-reactive protein (CRP) and lactate dehydrogenase (LDH), there was no statistical difference. Conclusion: It is a new disease, with few data, mainly in the studied population. Our sample was a reduced sample, however it was surprising to see a lower inflammatory tendency, although without statistical significance and with mortality similar to the general population. In addition, it is worth emphasizing the importance shown on the neutrophil / lymphocyte ratio of admission demonstrated by the ROC curve in patients who evolve in need of an ICU care.
