AbstractThis study compared the differences in the clinical manifestations, treatment courses and clinical turnover between mild and moderate coronavirus disease 2019 (COVID-19). Clinical data of the patients with imported COVID-19 admitted to Beijing Xiaotangshan Designated Hospital between March 15 and April 30, 2020, were retrospectively analysed. A total of 53 COVID-19 patients were included, with 21 mild and 32 moderate cases. Compared with the mild group, the moderate group showed significant differences in breathing frequency, lymphocyte count, neutrophil percentage, neutrophil/lymphocyte ratio, procalcitonin, C-reactive protein, and dynamic erythrocyte sedimentation rate. In the moderate group, 87.5% exhibited ground-glass opacities, 14% exhibited consolidative opacities, 53.1% exhibited local lesions and 68.8% exhibited unilateral lesions. The proportion of patients who received antiviral or antibiotic treatment in the moderate group was higher than that in the mild group, and the number of cases that progressed to severe disease in the moderate group was also significantly higher (18.7% vs. 0%, p = 0.035). Compared with patients with mild COVID-19, those with moderate COVID-19 exhibited more noticeable inflammatory reactions, more severe pulmonary imaging manifestations and earlier expression of protective antibodies. The overall turnover of the moderate cases was poorer than that of the mild cases.

Aim. Analysis of clinical manifestations, laboratory and instrumental examination data in SARS-CoV-2 patients with taking into account the disease severity and outcome.Materials and methods. The study included 92 patients with confirmed coronavirus infection, including 15 lethal cases, hospitalised at the Vasilenko Clinic of Internal Disease Propaedeutics, Gastroenterology and Hepatology of the Sechenov University in April 2020. The analysis included demographic data, the presence of concomitant diseases, chest computed tomography (CT) results, laboratory tests (including SARS-CoV-2-diagnostic PCR, general and metabolic blood panels, coagulogram) and the duration of disease.Results. Patients infected with SARS-CoV-2 usually exhibit lymphopenia (p ≤ 0.001), leucocytosis, the elevated neutrophils (p ≤ 0.05), neutrophil-lymphocyte ratio (p ≤0,05), C-reactive protein (p ≤ 0.05), ferritin (p ≤ 0.05), D-dimer (p ≤ 0.05) and fibrinogen (p ≤ 0.05), altered prothrombin time (p ≤ 0.05) and INR (p ≤ 0.05). In a critical coronavirus infection, the pulmonary lesion exceeds 50% (corresponds to CT3 — CT4). The risk of critical SARS-CoV-2 infection increases with elder age (p ≤ 0.001), associates with the male gender and presence of concomitant diseases, such as obesity (p < 0.01), diabetes mellitus (p < 0.001), hypertension (p ≤ 0.001), CHD (p ≤ 0.001) and atrial fibrillation (p <0.05).Conclusion. The risk of severe and adverse coronavirus infection is significantly higher in elder comorbid patients.

Introduction. Chikungunya virus infection (CKV) may lead to chronic arthritis in up to 40% of the patients. There are previous data regarding positive auto antibodies in CKV. Objective is to systematically evaluate the prevalence of auto antibodies in CKV patients. Methods. All study participants had clinical manifestations being CKV positive at least serologally or by RT-PCR data. The following autoantibodies were assessed: antinuclear antibodies (ANA), anti-dsDNA, anti-Sm, anti-Ro/SS-A, anti-La/SS-B, anti-U1RNP, IgG and IgM anticardiolipin, anticyclic citrullinated peptide (antiCCP), rheumatoid factor (RF), antiribosomal P protein, lupus anticoagulant, anti-Jo-1 and anti-Scl-70. CH100, C3 and C4 complement components, serum levels of immunoglobulins, C-reactive protein, erythrocyte sedimentation rate, alpha1-acid glycoprotein, antithyroglobulin, antithyroperoxidase, TRAb, 25 hydroxyvitamin D (25OHD), dengue and zika IgG and IgM antibodies were also measured. Results. 30 CKV patients were included. Mean age was 59.1±15.7 years, 85% females and 77% Caucasian subjects. Disease duration comprised 4.9±4.0 months. Oligoarthritis was observed in 93% cases. Mean C-reactive protein levels were 10.1±6.8 ng/dL, erythrocyte sedimentation rate — 34.2±19.9 mm/1st hour and alpha1-acid glycoprotein 115.5±52.6 mg/dL. Intramuscular betamethasone depot single dose injection was administered in 54%, prednisone — in 15% and methotrexate — in 23% cases. Importantly, 1/30 (3.3%) cases was positive for ANA, 4/30 (13.3%) — for RF and none was positive for anti-CCP or any other autoantibodies. Complement and immunoglobulin levels were all within the normal range. Low levels of 25OHD were observed in 88% cases.

Objective. Our aim was to evaluate the significance of homocysteine (Hcy) in Behcet's disease (BD) and the association of elevated Hcy levels associated with the indices of inflammation in BD.Methods. Untreated 70 patients with BD and 33 healthy individuals were included into the study. Hcy, tumor necrosis alpha (TNF-), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were evaluated with respect to activity and specific individual clinical manifestations of the disease.Results. Hcy levels were found significantly elevated in active BD when compared to inactive BD and healthy controls. Hcy levels were found to have high correlation with the number of active clinical manifestations increased. A significant positive correlation was found between serum Hcy and TNF- levels, CRP, and ESR. Hcy was found to be the best predictor of TNF- among other parameters.Conclusion. Hcy may involve in the pathogenesis of BD by inducing inflammation.

In COVID-19, a percentage of patients develop severe disease, with high mortality, since has been necessary to study its characteristics to stop the progression of the disease. A retrospective study was carried out in a cohort of 150 adult patients attended at Manuel Fajardo Hospital in Villa Clara, Cuba, from March to June 2020. Demographic, clinical, laboratory, gasometric and radiological variables measured at hospital admission were analyzed, defining two groups of patients according to clinical evolution: severe and non-severe. For the comparison of the groups a bivariate analysis was performed, with the objective of determining those variables with a significant association to severity. Of the total number of patients, 26 (17.3%) evolved to severity and 124 (83.7%) evolved satisfactorily. Severe patients were characterized by advanced age (mean: 83 years) and comorbidities; the most significant being hypertension, diabetes mellitus, heart disease, chronic kidney disease and cancer (p< 0.0001). Polypnea and diarrhea were the clinical manifestations with the highest association with severity (p<0.0001), followed by fever (p=0.0157). The quick SOFA prognostic scale proved to be a useful instrument to evaluate patients at admission. Laboratory variables: neutrophils, lymphocytes, neutrophil/lymphocyte ratio, hemoglobin and lactate dehydrogenase were the most associated with severity (p<0.0001). Leukocytes, lactate, D-dimer, C-reactive protein, glycemia and calcium also showed significant results (p<0.05). Of the gasometric variables, arterial oxygen pressure and saturation were the most significantly associated with severity; as well as the presence of pulmonary infiltrates or consolidation in the chest X-ray (p<0.0001). The study allowed us to identify variables at hospital admission associated with progression to severe forms of the disease.

Interactions of CRP with various substrates in the presence of human serum have been shown to result in efficient activation of C components C1-C5. We now report the ability of CRP to initiate C-dependent hemolysis. For this purpose CRP was isolated by affinity chromatography using pneumococcal CPS and gel filtration; its purity was established by several criteria. Erythrocytes were coated with CPS (E-CPS) and passively sensitized with CRP. C-dependent lysis of these cells was observed upon the addition of suitably absorbed human serum, and the efficiency of hemolysis compared favorably with that initiated by rabbit IgG anti-CPS antibody. CRP also sensitized E-CPS for lysis by guinea pig C; partial lysis was seen when C4-deficient guinea pig serum was used, suggesting that CRP also shares with antibody the ability of CRP to fully activate the C system and provide further evidence for a role for CRP similar to that of antibody in the initiation and modulation of inflammatory reactions via the complete system.

BACKGROUND: The diagnosis of osteomyelitis is a key step of diabetic foot management. Procalcitonin (PCT) is a novel infection marker. This study aimed to investigate the diagnostic value of procalcitonin and other conventional infection markers and clinical findings in diagnosis of osteomyelitis in diabetic foot patients. METHODS AND MATERIALS: This diagnostic value study was carried out on ninety patients with diabetic infected foot ulcers admitted in Kashan Beheshti Hospital, 2016. After obtaining consent, 10 cc blood sample was taken for measuring serum PCT, CBC, ESR, CRP and FBS. Clinical characteristics of the wounds were noted. Magnetic resonance imaging of the foot was performed in all patients to diagnose osteomyelitis. All statistical analyses were done with the use of SPSS-16. RESULTS: PCT levels were 0.13 ± 0.02 ng/mili patients with osteomyelitis (n= 45) and 0.04 ± 0.02 ng/ml in patients without osteomyelitis (n= 45). PCT, Erythrocyte sedimentation rate and C-reactive protein was found significantly higher in patients with osteomyelitis (p< 0.001). The ROC curve was calculated for PCT. The area under the ROC curve for infection identification was 1 (p< 0.001). The best cut-off value for PCT was 0.085 ng/ml. Sensitivity, specificity, and positive and negative predictive values were 100%, 97.8%,97.8% and 100%, respectively. CONCLUSION: In this group of patients, PCT was useful to discriminate patients with bone infection. Also, Erythrocyte sedimentation rate and C-reactive protein can be used as a marker of osteomyelitis in diabetic patients.

Idiopathic granulomatous mastitis (IGM) is a rare inflammatory breast disease mimicking breast cancer. Limited research has been conducted on the application of serum biomarkers. This study aims to investigate the association of serum biomarkers with disease severity in patients with IGM. From November 2011 to March 2020, medical records of patients with IGM were reviewed. Serum cytokine levels were measured in patients and healthy controls between July 2018 and March 2020. A total of 41 patients with histologically proven IGM were found. Serum interleukin (IL)-6 level was significantly higher in patients with IGM (n = 11) than healthy controls (n = 7). Serum IL-6 and C-reactive protein (CRP) levels were significantly higher in patients with severe disease than mild and moderate disease. Serum IL-6 (Spearman’s ρ = 0.855; p < 0.001) and CRP (Spearman’s ρ = 0.838; p = 0.001) levels were associated with time to resolution. A higher serum CRP level was associated with a longer time to resolution (B = 0.322; p < 0.001) in multiple linear regression analysis. Serum IL-6 and CRP levels can be used as biomarkers for the evaluation of disease severity in IGM. IL-6 may play a crucial role in the immunopathology of IGM.

BACKGROUND: Lymphocyte-to-C-reactive protein ratio (LCR) has been used as a post-surgical prognostic biomarker in patients with gastric and colorectal cancer. However, its relationship with early postoperative complications in these patients is unknown. In this study, we aimed to reveal the relationship between LCR and postoperative complications. METHODS: Eighty-one patients operated for stomach and colorectal cancer between January 2020 and August 2020 were prospectively analyzed. On preoperative and postoperative days 1, 3 and 5, other inflammatory parameters, mainly LCR, neutrophil lymphocyte ratio (NLR), were recorded. The patients were divided into two groups according to Clavien-Dindo classification as stage III and higher complications major, stage I-II/non-complication minor. RESULTS: Fifty seven patients were operated for colorectal cancer, 24 patients for gastric cancer. The mean age of the patients was 65.6 ± 12.6, 34.6% of them was women. Age, operation time and hospital stay were significantly different between the groups (p= 0.004, p= 0.002, p< 0.001). Major complications developed in 18 patients. On postoperative day 5, LCR found superior diagnostic accuracy in predicting major postoperative complications compared to other inflammatory markers. On the postoperative 5th day, the cut-off value of LCR was 0.0034, 88.8% (71.9–94.8) sensitivity, and 85.7% (73.6–95.4) selectivity. CONCLUSION: Among different inflammatory markers, postoperative LCR is a safe and effective predictor of postoperative complications, especially after gastric and colorectal cancer surgery on day 5.
