  • 宏基因组二代测序辅助诊断军团菌病伴横纹肌溶解和急性肾损伤一例

    目的 加强临床医生对军团菌病多器官损害临床特点的认识,针对目前军团菌诊断的难点,重视宏基因组二代测序(metagenomic next-generation sequencing,mNGS)在本病诊断中的应用价值,以早期诊断与精准治疗,改善军团菌病患者的预后。方法 分析 1 例经 mNGS 确诊的嗜肺军团菌病患者的临床特点、治疗过程及预后。结果 患者男,61 岁,因“发热、咳嗽伴乏力 3 d”就诊。发病初期除呼吸道症状外,合并多系统症状。住院期间,在肺泡灌洗液及肺组织中,mNGS 检出嗜肺军团菌,结合临床特点诊断军团菌病。患者经有创呼吸、抗感染、血液透析、保肝等综合治疗后,最终顺利出院。结论 对于病程短,以肺炎表现为主伴多器官受累的疾病,尤其伴肌酸激酶显著升高者应警惕军团菌感染可能。对于病情危重且少痰或无痰的患者,在缺少其他检测方法(如军团菌尿抗原)的情况下,可行纤维支气管镜取肺泡灌洗液或经皮肺穿刺取肺组织进行mNGS检查,以早期明确病原体。军团菌肺炎伴发横纹肌溶解和急性肾损伤时,及早予以针对病因及并发症的综合治疗有助于改善患者预后。

  • A Case of Renal Contusion with Acute Pulmonary Embolism: Treatment Experience and Literature Review

    ObjectiveTo investigate the anticoagulant drug treatment decision for patients with renal contusion and acute pulmonary embolism, and to enhance the level of treatment for this disease. MethodsA retrospective analysis of the clinical data of a patient with renal contusion and acute pulmonary embolism treated at the West China Hospital of Sichuan University, along with a relevant literature review. Databases including PubMed, Ovid Medline, Embase, VIP, Wanfang and Chinese National Knowledge infrastructure were searched using the keywords as “Pulmonary embolism” AND “Hemorrhage”from January 1983 to December 2023. ResultThe patient was a 21-year-old male who presented with right kidney contusion for 5 days and dyspnea for 1 day. The abdominal CT scan revealed a ruptured right kidney accompanied by hemorrhage and hematoma in the surrounding tissue. Abdomen ultrasound: a low echogenic area measuring approximately 10.6 cm×2.8 cm is noted around the right kidney. The CT pulmonary angiography (CTPA) demonstrated filling defects at the bifurcation of the pulmonary trunk, as well as within the upper and lower lobes of both lungs and their respective branches. The blood gas analysis of patient indicated (face mask oxygen therapy at 10 L/min, oxygenation index of 120): pH 7.456, PCO2 24.9 mm Hg, PO2 73.2 mm Hg. His myocardial markers were Myoglobin: 79.21 ng/ml, Troponin T: 58.7 ng/L, BNP: 2062 ng/L. The patient was diagnosed with renal contusion and pulmonary embolism, and was treated with subcutaneous heparin(initial dose is given as an 80 IU/kg intravenous bolus, followed by a continuous infusion of 12-18 IU/kg/h) and low-molecular-weight heparin at a dose of 0.8 ml every 12 hours one after another for anticoagulation, along with symptomatic treatment. Following the intervention, the patient's respiratory distress showed significant improvement, and subsequent arterial blood gas analysis indicated enhanced oxygenation. Then, the anticoagulant medication was adjusted to oral rivaroxaban anticoagulation for 6 months, follow-up CTPA scan revealed complete resolution of the pulmonary embolism and the abdominal CT scan indicated a reduction in the extent of patchy low-density shadows surrounding the right kidney, leading to the discontinuation of anticoagulation therapy. After searching the above-mentioned databases, total of 26 articles were identified that reported on 30 patients diagnosed with high-risk bleeding and acute pulmonary embolism; among these, 3 patients succumbed while 27 exhibited clinical improvement. ConclusionsPatients with renal contusion and acute pulmonary embolism can be safely and effectively treated with low-dose heparin anticoagulation under close monitoring. High-risk bleeding patients with acute pulmonary embolism present a significant challenge in clinical practice. After weighing the risks of bleeding disorders and the adverse outcomes of pulmonary embolism, it is necessary to find the optimal balance between anticoagulation and bleeding. Consequently, the formulation of personalized treatment strategies in accordance with established guidelines can enhance patient outcomes.
