Objective To investigate the predictive value of B-type natriuretic peptide(BNP)for acute exacerbation of chronic obstructive pulmonary disease(AECOPD)complicated by right heart failure(RHF).Methods This study selected AECOPD patients admitted to Jiangyin Hospital Affiliated to Nantong University and Nanjing Chest Hospital from January 2022 to January 2024 as ob-jects.According to the inclusion and exclusion criteria,122 patients were ultimately enrolled.The patients were divided into observation group(AECOPD with RHF,n=72)and control group(AECOPD without RHF,n=50)based on whether they had RHF.Differences in various indicators between the two groups were compared,and the predictive value of BNP for AECOPD patients with RHF was assessed through Logistic regression analysis and receiver operating characteristic(ROC)curves.The cut-off value of BNP was determined using the ROC curve.Results Statistically signifi-cant differences were observed between the two groups in terms of gender,body temperature,albumin,blood glucose,chloride ions,pulmonary artery pressure(PAP),and BNP levels(P＜0.05).Logistic regression analysis showed that BNP was an independent predictor for AECOPD patients with RHF(OR=1.03;95％CI,1.01 to 1.04;P＜0.05).The ROC curve results indicated that when the BNP cut-off value was 83.5 pg/mL,the sensitivity was 0.820,the specificity was 0.972,and the Youden index was 0.792.The area under the curve for BNP was 0.875(95％CI,0.800 to 0.949,P＜0.001).When the BNP level in AECOPD patients exceeded 83.5 pg/mL,the incidence of RHF significantly increased.Conclusion Patients with AECOPD complicated by RHF have higher plasma BNP levels than those without RHF,and BNP has significant predictive value for determining whether AECOPD patients have RHF.

Objective·To investigate the association of serum osteoglycin(OGN)levels with renal function and blood pressure in non-diabetic patients with hypertension.Methods·Hypertensive patients without a diagnosis of diabetes mellitus were recruited from the Hypertension Department of Ruijin Hospital,Shanghai Jiaotong University School of Medicine.A total of 36 renal dysfunction patients(renal dysfunction group)and 38 normal renal function patients(normal renal function group),matched for age,gender and clinic blood pressure,were included in this study.Serum OGN concentrations were measured by the enzyme-linked immunosorbent assay(ELISA).Estimated glomerular filtration rate(eGFR)was calculated from serum creatinine using the Chronic Kidney Disease Epidemiology Collaboration(CKD-EPI)equation.The serum OGN levels were compared between the renal dysfunction group and the normal renal function group.The correlations of serum OGN level with eGFR and blood pressure were analyzed.Results·There was no significant statistical difference in serum OGN levels between the renal dysfunction group and the normal renal function group(P=0.708).Serum OGN levels were not significantly associated with eGFR(P=0.952).In the renal dysfunction group,mean arterial pressure,age and current smoking status were relevant factors of serum OGN levels(P<0.05).After adjustment for confounders,serum OGN levels were independently associated with clinic systolic and diastolic blood pressure,24-hour ambulatory mean systolic and diastolic blood pressure in the renal dysfunction group(P<0.05),but not in the normal renal function group(P?0.05).Conclusion·In non-diabetic patients with hypertension,serum OGN levels are not significantly associated with eGFR.In patients with renal dysfunction,higher serum OGN levels are independently associated with higher clinic systolic blood pressure,clinic diastolic blood pressure,24-hour ambulatory mean systolic and diastolic blood pressure.

Objective:To investigate the clinical characteristics and interventions associated with drug-induced anaphylaxis in the emergency infusion room.Methods:Bases on the adverse drug reaction database from the emergency medicine center of the First Affiliated Hospital of Nanjing Medical University, clinical data of patients who experienced drug-induced anaphylaxis in the emergency infusion room between November 2019 and November 2023 were collected, including gender, age, history of previous adverse drug reactions, allergy history, Charlson comorbidity index, medication details, information related to drug-induced anaphylaxis (onset time, clinical manifestations), interventions, outcomes, and follow-up. The clinical characteristics and interventions in these patients were analyzed.Results:During the study period, a total of 398 772 patients in the emergency infusion room in our hospital received intravenous infusion of drugs. Of them, 625 cases developed adverse drug reactions (ADRs) and 75 cases developed drug-induced anaphylaxis, accounting for 0.02% (75/398 772) of the total infusion patients and 12.0% (75/625) of all ADR cases. Of the 75 patients with anaphylaxis, 30 cases (40%) were classified as grade Ⅱ, and 45 cases (60%) as grade Ⅲ, with no grade Ⅳ cases. The most common drugs involved in 75 cases of anaphylaxis were anti-infective drugs (41 cases, 54.7%). Drug-induced anaphylaxis exhibited diverse clinical manifestations, with cardiovascular symptoms being the most common, primarily varying degrees of transient hypotension (67 cases, 89.3%), followed by systemic and neurological symptoms, including profuse sweating (31 cases, 41.3%) and dizziness (28 cases, 37.3%). All 75 patients with anaphylaxis were treated with measures such as discontinuation of medication, replacement of infusion sets, rapid assessment of circulation and respiration, and monitoring of vital signs, of which 65 (86.7%) received rapid intravenous infusion for volume expansion, 6 (8.0%) received intravenous injection of glucocorticoids, 3 (4.0%) received intramuscular injection of 0.5 mg epinephrine, and 2 (2.7%) received antihistamines. All 75 patients showed improvement in symptoms, and no sequelae or deaths were found.Conclusions:In the emergency infusion room, the severity of anaphylaxis is mainly grade Ⅱ and Ⅲ with a good prognosis after timely intervention. The treatment measures mainly focus on rapid intravenous infusion for volume expansion, and the use of epinephrine is relatively low.

Objective:To explore the clinical characteristics of adverse reactions induced by levofloxacin in the emergency infusion unit.Methods:The study was designed as a single center prospective cohort study. Data of adverse drug reaction (ADR) in the Infusion Unit of Emergency Medicine Center of First Affiliated Hospital of Nanjing Medical University was managed, recorded and collected according to the pre-formulated "emergency infusion unit drug adverse reaction management process" and "strengthening the reporting of observational studies in epidemiology (STROBE)". The incidence, severity, clinical characteristics, intervention measures, outcomes, and follow-up of adverse reactions induced by levofloxacin from November 2019 to October 2022 was summarized and analyzed.Results:A total of 426 cases of ADR occurred within the set time period, of which 62 (14.55%) were related to levofloxacin, involving 27 males (43.55%) and 35 females (56.45%) with a median age of 39 years. Among the 62 levofloxacin-related ADRs, 96.77% (60/62) occurred within 2 hours of intravenous infusion of levofloxacin; the severity of 44 (70.97%), 10 (16.13%) and 8 (12.90%) cases of ADRs was classified as grade 1, 2, and 3, respectively, and no grade 4 ADRs occurred. The most common clinical symptoms were skin and mucosa reactions, including rash and itching, followed by cardiovascular system and nervous system manifestations, including hypotension, palpitation, and dizziness. The skin and mucosa manifestations were more common in patients with severity grade 1 ADRs, while the cardiovascular, digestive, respiratory nervous system and systemic manifestations were more common in those with severity grade 2 and 3 ADRs; the differences were statistically significant (all P<0.05). After the occurrence of ADRs, levofloxacin was withdrawn in all the 62 patients, the infusion set was replaced, and infusion of 0.9% sodium chloride injection were used to flush the tube. Additionally, 24 patients (38.71%) were given drug intervention, including epinephrine in 2 patients. After the above intervention, the symptoms of all patients were relieved, with a median response time of 49 minutes. Conclusions:Levofloxacin was one of the common drugs causing ADR in the emergency infusion unit. The clinical manifestations were mainly rashes and itching, most of which were mild in severity. Timely discontinuation of levofloxacin and drug interventions often help get a good prognosis. However, the treatment procedure of severe ADRs remain to be standardized.
