Severe fever with thrombocytopenia syndrome (SFTS), a tick-borne infectious disease, is difficult to differentiate from other common febrile diseases. Clinically distinctive features and climate variates associated with tick growth can be useful predictors for SFTS. This retrospective study (2013–2019) demonstrated the role of climatic factors as predictors of SFTS and developed a clinical scoring system for SFTS using climate variables and clinical characteristics. The presence of the SFTS virus was confirmed using reverse transcription polymerase chain reaction (RT-PCR) tests. In the univariate analysis, the SFTS-positive group was significantly associated with higher mean ambient temperature and humidity compared with the SFTS-negative group (22.5 °C vs. 18.9 °C; 77.9% vs. 70.7%, all p < 0.001). In the multivariate analysis, poor oral intake (Odds ratio [OR] 5.87, 95% CI: 2.42–8.25), lymphadenopathy (OR 7.20, 95% CI: 6.24–11.76), mean ambient temperature ≥ 20 °C (OR 4.62, 95% CI: 1.46–10.28), absolute neutrophil count ≤ 2000 cells/μL (OR 8.95, 95% CI: 2.30–21.25), C-reactive protein level ≤ 1.2 mg/dL (OR 6.42, 95% CI: 4.02–24.21), and creatinine kinase level ≥ 200 IU/L (OR 5.94, 95% CI: 1.42–24.92) were significantly associated with the SFTS-positive group. This study presents the risk factors, including ambient temperature and clinical characteristics, that physicians should consider when suspecting SFTS.

Abstract Background Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne emerging infectious disease caused by SFTS virus (SFTSV). Mortality of SFTS estimated to be 21.8% in South Korea, and this disease is difficult differential diagnosis. Here, we analyzed clinical characteristics between SFTS positive group (SPG) and negative group (SNG) in a primary clinical setting. Methods In this prospective observational study, data were collected on patients with SFTS test performed at the single teaching hospital, in South Korea, between April 2013 and December 2018. The association between each demographic, climatic, clinical, and laboratory variable was assessed. All SFTS was confirmed at the KCDC by detecting the M segment gene of SFTSV RNA using reverse transcription-polymerase chain reaction (RT–PCR), and were confirmed at our laboratory by S segment gene of SFTSV RNA using RT–PCR about patient’s family member and those with close contact. Results Of the 199 patients in the study periods, 61 (31%) were SPG and 138 (69%) were SNG. Mean age was 55.1 ± 20.3 years, and 103 (52%) patients were male. In SPG, the comorbidity score and history of tick bite were significantly higher compared with SNG. SPG and SNG were prevalent in summer and autumn, respectively (60.7% vs. 45.7%, P < 0.05). SPG was associated with mean outdoor temperature, humidity and rainfall compared with SNG (22.9°Cvs. 18.9 ℃; 78.8% vs. 70.6%; 12.6 mm vs. 8.5 mm, all P < 0.01). Dizziness, poor oral intake, nausea, and diarrhea were common in SPG. In laboratory findings, white blood cell counts, absolute neutrophil count, and C-reactive protein were significantly lower in SPG. Lymphocyte fraction, activated partial thromboplastin time, and creatinine phosphokinase were significantly higher in SPG. Case fatality of the SPG and SNG were 9.8% and 1.0%, respectively. In multivariate analysis, mean outdoor temperature, humidity, dizziness, and low CRP were predictive factors in SPG. Conclusion Early prediction of SFTS diagnosis is important because this emerging zoonotic disease was a high fatality in endemic areas. When a physician wants to do SFTS test, they would consider according to this predictive variable for differentiating SFTS in primary care settings. Disclosures All authors: No reported disclosures.

Background:IgA vasculitis (IgAV) could be limited to skin or evolve into a systemic disease, affecting characteristically joints, gastrointestinal tract and/or kidneys.Objectives:We aimed to look for differences between adult IgAV patients with disease limited to skin compared to systemic IgAV.Methods:Medical records of histologically proven adult IgAV cases, diagnosed between January 2010 and December 2020 at our secondary/tertiary rheumatology centre were analyzed.Results:During the 132-month observation period we identified 328 new IgAV cases (59.5% males, median (IQR) age 64.3 (45.1; 76.1) years). Ninety-four (40.2%) patients had skin limited disease, and the rest systemic IgAV.Clinical differences between skin limited and systemic adult IgAV are presented in table 1. Adults with IgAV limited to skin were significantly older, had less commonly skin lesions above the waistline and a lower level of C reactive protein compared to patients with a systemic disease. There were no differences in the frequency of skin necroses between the compared IgAV subgroups. The frequency of potential vasculitis triggers (prior infections, new medications, malignancy) was similar between the compared subgroups.Table 1.Clinical characteristics of IgA vasculitis patients with skin limited and systemic diseaseClinical characteristicsSkin limited IgAV (94)Systemic IgAV (234)P valueMale gender (%)54.361.50.263Age (years)*68.0 (55.0-80.5)61.5 (41.7-75.8)0.007Current smoker (%)13.821.80.123Antecedent infection (%)28.733.80.434New medication23.423.51.0History of cancer12.810.70.569Symptom duration (days)*7 (5-21)8 (5-14)0.756Purpura above waistline36.255.60.002Skin necroses (%)52.145.70.329ESR /mm/h) *32 (18-52)34 (17-53)0.873CRP (g/l) *13.5 (1-32)30 (11-68)<0.001Elevated serum IgA (%)50.649.10.892Legend: * median and IQR;Follow up data were available for 250 (76.2%) patients.

AbstractBACKGROUNDIncreases in circulating LDL cholesterol (LDL-C) and high-sensitivity C-reactive protein (hsCRP) concentrations are significant risk factors for cardiovascular disease (CVD). We assessed direct LDL-C and hsCRP concentrations compared to standard risk factors in the Framingham Offspring Study.METHODSWe used stored frozen plasma samples (−80 °C) obtained after an overnight fast from 3147 male and female participants (mean age, 58 years) free of CVD at cycle 6 of the Framingham Offspring Study. Overall, 677 participants (21.5%) had a CVD end point over a median of 16.0 years of follow-up. Total cholesterol (TC), triglyceride (TG), HDL cholesterol (HDL-C), direct LDL-C (Denka Seiken and Kyowa Medex methods), and hsCRP (Dade Behring method) concentrations were measured by automated analysis. LDL-C was also calculated by both the Friedewald and Martin methods.RESULTSConsidering all CVD outcomes on univariate analysis, significant factors included standard risk factors (age, hypertension, HDL-C, hypertension treatment, sex, diabetes, smoking, and TC concentration) and nonstandard risk factors (non-HDL-C, direct LDL-C and calculated LDL-C, TG, and hsCRP concentrations). On multivariate analysis, only the Denka Seiken direct LDL-C and the Dade Behring hsCRP were still significant on Cox regression analysis and improved the net risk reclassification index, but with modest effects. Discordance analysis confirmed the benefit of the Denka Seiken direct LDL-C method for prospective hard CVD endpoints (new-onset myocardial infarction, stroke, and/or CVD death).CONCLUSIONSOur data indicate that the Denka Seiken direct LDL-C and Dade Behring hsCRP measurements add significant, but modest, information about CVD risk, compared to standard risk factors and/or calculated LDL-C.

Abstract Background The coronavirus disease 2019(COVID-19) has affected mortality worldwide. The Cox proportional hazard (CPH) model is becoming more popular in time-to-event data analysis. This study aimed to evaluate the clinical characteristics in COVID-19 inpatients including (survivor and non-survivor); thus helping clinicians give the right treatment and assess prognosis and guide the treatment. Methods This single-center study was conducted at Hospital for COVID-19 patients in Birjand. Inpatients with confirmed COVID-19 were included. Patients were classified as the discharged or survivor group and the death or non-survivor group based on their outcome (improvement or death). Clinical, epidemiological characteristics, as well as laboratory parameters, were extracted from electronic medical records. Independent sample T test and the Chi-square test or Fisher’s exact test were used to evaluate the association of interested variables. The CPH model was used for survival analysis in the COVID-19 death patients. Significant level was set as 0.05 in all analyses. Results The results showed that the mortality rate was about (17.4%). So that, 62(17%) patients had died due to COVID-19, and 298 (83.6%) patients had recovered and discharged. Clinical parameters and comorbidities such as oxygen saturation, lymphocyte and platelet counts, hemoglobin levels, C-reactive protein, and liver and kidney function, were statistically significant between both studied groups. The results of the CPH model showed that comorbidities, hypertension, lymphocyte counts, platelet count, and C-reactive protein level, may increase the risk of death due to the COVID-19 as risk factors in inpatients cases. Conclusions Patients with, lower lymphocyte counts in hemogram, platelet count and serum albumin, and high C-reactive protein level, and also patients with comorbidities may have more risk for death. So, it should be given more attention to risk management in the progression of COVID-19 disease.

During the coronavirus disease 2019 (COVID-19) pandemic, the number of pregnant women and neonates suffering from COVID-19 increased. However, there is a lack of evidence on clinical characteristics and neonatal outcomes in pregnant women with COVID-19. We evaluated short-term outcomes (4 weeks postdischarge) and symptoms in neonates born to mothers infected with COVID-19. In this retrospective cohort study, we included all neonates born to pregnant women with COVID-19 admitted to Ayatollah Rohani Hospital, Babol, Iran, from February 10 to May 20, 2020. Clinical features, treatments, and neonatal outcomes were measured. Eight neonates were included in the current study. The mean gestational age and birth weight of newborns were 37 ± 3.19 weeks (30₊6-40) and 3077.50 ± 697.64 gr (1720-3900), respectively. Apgar score of the first and fifth minutes in all neonates was ≥8 and ≥9 out of 10, respectively. The most clinical presentations in symptomatic neonates were respiratory distress, tachypnea, vomiting, and feeding intolerance. This manifestation and high levels of serum C-reactive protein (CRP) in three infants are common in neonatal sepsis. The blood culture in all of them was negative. They have been successfully treated with our standard treatment. Our pregnant women showed a pattern of clinical characteristics and laboratory results similar to those described for nonpregnant COVID-19 infection. This study found no evidence of intrauterine or peripartum transmission of COVID-19 from mother to her child. Furthermore, the long-term outcomes of neonates need more study.

Abstract During the Coronavirus disease 2019 (COVID-19) pandemic, the number of pregnant women and neonates suffering from COVID-19 increased. However, there is a lack of evidence on clinical characteristics and neonatal outcomes in pregnant women with COVID-19. We evaluated short-term outcomes (4 weeks post-discharge) and symptoms in neonates born to mothers infected with COVID-19. In this retrospective cohort study, we included all neonates born to pregnant women with COVID-19 who were admitted to Ayatollah Rohani Hospital, Babol, Iran, from February 10 to May 20, 2020. Clinical features, treatments, and neonatal outcomes were measured. Eight neonates were included in the current study. The mean gestational age and birth weight of newborns were 37 ± 3.19 weeks (30₊6 − 40) and 3077.50 ± 697.64 gr (1720–3900) respectively. Apgar score of the first and fifth minutes in all neonates was ≥ 8 and ≥ 9 out of 10 respectively. The most clinical presentations in symptomatic neonates were respiratory distress, tachypnea, vomiting, and feeding intolerance. This manifestation and high levels of serum C-reactive protein (CRP), in three infants, are common in neonatal sepsis. The blood culture in all of them was negative. They have been successfully treated with our standard treatment. Our pregnant women showed a pattern of clinical characteristics and laboratory results almost similar to those described for non-pregnant COVID-19 infection. This study found no evidence of intrauterine or peripartum transmission of COVID-19 from mother to her child. Furthermore, the long-term outcomes of neonates need more study.

Background: The optimal management of perianal abscess in children is controversial.Purpose: To evaluate the efficiency of conservative treatment of perianal abscess in children and identify parameters that predict therapy failure.Methods: All cases of children younger than 14 years of age with perianal abscesses between 2001–2016 were evaluated.Results: Of the 113 enrolled patients, 64 underwent subsequent surgery for advanced disease (primary surgery group). Conservative treatment was initiated in 49 patients (primary conservative group) but was stopped because of inefficiency in 25 patients, who were referred for surgery after a median 7.03 days (range, 2 to 16 days). The other 24 patients (48%) initially achieved complete remission after conservative treatment, but 10 were readmitted after a median 34 months (range, 3 to 145 months) with recurrent disease. There were no significant differences in permanent success after conservative treatment between infants (10 of 29, 34%) and older children (4 of 20 [20%], <i>P</i>=0.122). Overall, conservative treatment alone was effective in only 14 of 113 patients. Recurrence after surgery occurred in 16 patients (25%) in the primary surgery group and 11 patients (22%) in the primary conservative group (<i>P</i>=0.75). Univariate analysis of predictors for conservative treatment failure revealed inflammatory values (C-reactive protein and white blood count, <i>P</i>=0.017) and abscess size (<i>P</i>=0.001) as significant parameters, whereas multivariate analysis demonstrated that only abscess size (odds ratio, 3.37; <i>P</i>=0.023) was significant.Conclusion: Conservative treatment of perianal abscess is permanently efficient in only a minority of children but is not associated with a higher recurrence rate after subsequent surgery. Abscess size is a predictor for therapy failure.

Abstract Background：The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been spreading globally. The information regarding the characteristics and prognosis of antibody non-responders with COVID-19 is scarce.Method: In this retrospective, single-center study, we included all the patients with confirmed COVID-19 using real-time reverse transcriptase-polymerase chain reaction (RT-PCR) admitted to the Fire God Mountain hospital from February 3, 2020, to April 14, 2020. A total of 1921 patients were divided into the antibody-negative group (n=94) and antibody-positive group (n=1827), and the 1:1 propensity score matching (PSM) was used to match two groups.Results: In the antibody negative group, 40 patients (42.6%) were male, 54 patients (57.4%) were female, and 49 patients (52.1%) were older than 65 years old. Cough was the most common symptoms in the antibody negative group. White blood cell counts (WBC) 6.6×109/L [5.0, 9.1], Neutrophils 4.3×109/L [3.1, 6.6], C-reactive protein 7.3 mg/L [1.3, 49.0], Procalcitonin (PCT) 0.1 ng/mL [0.0, 0.2], Interleukin-6 (IL-6) 64.2 [1.5, 28.7], Lactate dehydrogenase (LDH) 193.8 U/L [154.9,260.6], Creatine kinase 60.5 U/L [40.5, 103.7], Creatine kinase isoenzyme 10.3 ng/mL [8.2, 14.5], Urea nitrogen 5.3 mmol/L [4.0, 8.7] and Creatinine 77.7 μmol/L [60.6, 98.7] were significantly higher in antibody negative patients than in antibody positive group (P<0.005). The days of nucleic acid negative conversion in the antibody negative group was shorter than that in the antibody positive group (P < 0.001). Meanwhile, the hospitalization time of antibody negative patients was shorter than that of antibody positive patients (8.0 [6.0, 10.0] VS 13.0 [8.2, 23.0], P < 0.001).Conclusion: Some COVID-19 patients without specific antibodies had mild symptoms, but the inflammatory reaction caused by innate clinical immunity was more intense than those with antibodies, and the virus was cleared faster. The production of specific antibodies was unnecessary for SARS-CoV-2 clearance, and non-specific immune responses played an essential role in virus clearance.

Abstract Background: Systemic inflammatory response and nutritional status are closely related to tumor development, and both have been recognized as predictors of tumors. Our study investigated the effect on the prognosis of osteosarcoma by analyzing the ratio of lymphocytes to C-reactive protein (LCR) before surgery.Methods: Patients who were diagnosed with osteosarcoma and underwent surgery in the First Affiliated Hospital of Guangxi Medical University from 2012 to 2019 were included in this retrospective study. The albumin (g/L) +5 × total lymphocyte count (PNI), neutrophil/lymphocyte count (NLR), platelet/lymphocyte count (PLR) and platelet × neutrophil/lymphocyte count (SII) were calculated from preoperative peripheral white blood cells, C-reactive protein and serum albumin. The optimal cutoff values of LCR, PNI, NLR, PLR and SII were determined by receiver operating characteristic (ROC) analysis. According to the Optimal cutoff values, LCR, PNI, NLR, PLR and SII were divided into high and low groups. The Kaplan-Meier method was used to compare the overall survival (OS) between the high and low LCR groups. Univariate analysis was used to determine the influence of age, gender, tumor size, Enneking stage and neoadjuvant chemotherapy on the prognosis of osteosarcoma.The independent predictors of OS were determined by Cox multivariate analysis.Results: The optimal cutoff values for LCR, PNI, NLR, PLR and SII were 0.093, 48.4, 1.23, 157.03 and 314.27, respectively. A low preoperative LCR was significantly correlated with tumor metastasis, stage, NLR, PLR and SII. However, a low preoperative PNI was significantly associated with tumor metastasis, stage, and PLR.Kaplan-Meier survival analysis indicated that the postoperative OS was significantly correlated with preoperative LCR and PNI (P < 0.05). Univariate analysis showed that Enneking stage, metastasis and preoperative LCR, PNI, NLR, PLR and SII were important factors affecting OS (P < 0.05). For multivariate analysis, the results revealed that the preoperative LCR (HR, 0.401; 95% CI, 0.199-0.807; P = 0.01) and Enneking stage (HR, 2.717; 95%CI, 1.067-6.919; P = 0.036) is an independent prognostic factor affecting the postoperative OS of osteosarcoma.Conclusions: The high preoperative LCR is strongly associated with longer survival time in patients with osteosarcoma. Enneking stage and preoperative LCR may be important parameters for the prognosis of osteosarcoma.

Abstract Background: Gastric cancer (GC) is a complex multifactorial disease. Previous studies have revealed genetic variations associated with the risk of gastric cancer. The purpose of the present study was to determine the correlation between single-nucleotide polymorphisms (SNPs) of ZBTB20 and the risk of gastric cancer in Chinese Han population. Methods: We conducted a ‘case–control’ study involving 509 GC patients and 507 healthy individuals. We selected four SNPs of ZBTB20 (10934270 T/C, rs9288999 G/A, rs9841504 G/C and rs73230612 C/T), and used logistic regression to analyze the relationship between those SNPs and GC risk under different genetic models; multi-factor dimensionality reduction (MDR) was used to analyze the interaction of “SNP–SNP” in gastric cancer risk; ANOVA and univariate analysis were used to analyze the differences in clinical characteristics among different genotypes. Results: Our results showed that ZBTB20 rs9288999 is a protective factor for the risk of gastric cancer in multiple genetic models, of which the homozygous model is the most significant (OR = 0.48, P=0.0003); we also found that rs9288999 showed a significant correlation with reducing the risk of gastric cancer in different subgroups (BMI; age; gender; smoking or drinking status; adenocarcinoma); rs9841504 is associated with increased GC risk in the participants with BMI&gt;24 kg/m2; rs9841504 and rs73230612 are certainly associated with clinical characteristics of platelet and carbohydrate antigen 242, respectively. Conclusion: Our results suggest that ZBTB20 rs9288999 may be important for reducing the risk of GC in the Chinese Han population.
