Objective:To study the clinical features of histiocytic necrotizing lymphadenitis. Method: Eleven pa-tients with histiocytic necrotizing lymphadenitis were collected to analyze the clinical features, pathological features of biopsy lymph nodes,diagnosis and treatment. Result:Lymph node swelling of neck and persistent fever were de-tected in all patients. The leukocyte reduction and swiftness of ESR in serum were detected in most patients. The final diagnosis of histiocytic necrotizing lymphadenitis was confirmed by biopsy investigation of the pathology. The pathological features included distinctive necrosis, loss of lymph node structure, infiltration with histiocytes and lymphocytes, absence of neutrophils. All patients were treated with glucocorticoid for 2 to 4 months. The patients improved significantly and were not recurrence during follow up visit. Conclusion: There was no specific clinical manifestation of histiocytic necrotizing lymphadenitis and which easy to misdiagnose. Diagnosis of histiocytic ne-crotizing lymphadenitis relies on the pathological examination of enlarged lymph nodes.

Objective:To analyze and compare the clinical indicators and the liver failure-related prognostic score of patients with amanita phalloides poisoning with different prognoses, and to explore potential prognostic indicators.Methods:A retrospective case-control study was conducted. The clinical data of 52 patients with amanita phalloides poisoning admitted to the department of emergency of Xijing Hospital Affiliated to Air Force Medical University from September 2016 to September 2021 were collected, including general information (gender, age), clinical indicators at admission [mean arterial pressure (MAP), total bilirubin (TBil), aspartate transaminase (AST), alanine transaminase (ALT), albumin (ALB), serum creatinine (SCr), blood urea nitrogen (BUN), creatine kinase (CK), D-dimer, fibrinogen degradation product (FDP), prothrombin time (PT), activated partial thromboplastin time (APTT), prothrombin activity (PTA), international normalized ratio (INR), white blood cell count (WBC), platelet count (PLT)], liver failure-related prognostic score [sequential organ failure assessment (SOFA), chronic liver failure (CLIF)-SOFA score, European Foundation for the Study of Chronic Liver Failure-organ failure (CLIF-C OF)], and 28-day outcome. The clinical indicators and liver failure-related prognostic scores of the patients with different prognoses were compared. Receiver operator characteristic curve (ROC curve) was used to determine the prognostic value of statistically significant indicators between different prognosis of patients with amanita poisoning.Results:A total of 45 patients were enrolled, of which 38 survived and 7 died within 28 days. The coagulation indicators including PT, APTT, INR, and liver failure-related prognostic scores including SOFA score, CLIF-SOFA score, and CLIF-C OF score in the patients of death group were significantly higher than those in the survival group [PT (s): 69.59±15.94 vs. 25.99±4.64, APTT (s): 83.44±17.82 vs. 42.64±3.79, INR: 6.13±1.47 vs. 2.07±0.33, SOFA score: 11.57±1.38 vs. 6.03±0.77, CLIF-SOFA score: 9.86±2.17 vs. 5.55±0.67, CLIF-C OF score: 11.71±0.97 vs. 8.37±0.35], and PLT was significantly lowered (×10 9/L: 80.57±29.65 vs. 169.60±11.80, all P < 0.05). ROC curves showed that coagulation indicators including PT, APTT, INR, PLT, and liver failure-related prognostic scores including SOFA score and CLIF-C OF score were associated with the prognosis of patients with amanita phalloides poisoning, with the area under the ROC curve (AUC) of > 0.75. The sensitivity of the clinical indicators was above 85%, and the AUC and specificity of INR were the highest, which were 0.88 [95% confidence interval (95% CI) was 0.74-1.00] and 83.0%, respectively; meanwhile, the sensitivity of the liver failure-related prognostic scores was 100%, and the AUC and specificity of the CLIF-C OF score were the highest, which were 0.86 (95% CI was 0.74-0.99) and 66.0%, respectively. Conclusion:INR and CLIF-C OF score can be used to evaluate the poor prognosis of patients with amanita phalloides poisoning.
