Objective To explore the application and follow-up monitoring and diagnostic value of lung ultrasound (LUS) in elderly patients(≥75y) with novel coronavirus pneumonia (COVID-19). Methods Data of 25 COVID-19 elderly patients admitted to the Department of Internal Medicine from November 1, 2022 to January 15, 2023 were retrospectively analyzed and summarized. In addition to clinical data, dynamic monitoring of LUS was performed, and the results were compared with lung CT results. The examination results, as well as the prediction and impact on the course of disease were observed. Results LUS imaging indicated that patients had different degrees of interstitial lung injury, including discrete type B line (interstitial exudation) or fusion type B line (alveolar infiltration) and lung consolidation (alveolar collapse). With the improvement of the disease, the range of lung consolidation seen in LUS was reduced, the B-line was gradually sparse to dissipate, and the A-line appeared. Conclusions The results of LUS and chest CT in the same period are consistent. LUS examination is safe, simple, reproducible, and can be monitored dynamically in real time. It can be used as a primary screening method, and also be used in special patients to assist clinical treatment decision-making.

目的 分析对比肺部受累的惠普尔病与初治菌阴肺结核患者的临床特征,提高对肺部受累的惠普尔病的认识、诊断及鉴别水平。方法 回顾性收集20例肺部受累的惠普尔病为病例组,并随机选取同期56例初治菌阴肺结核患者为对照组进行对比,探讨肺部受累的惠普尔病的临床特征。结果 病例组中老年（>37岁）、急性或亚急性的病程比例高于对照组（P<0.05）。CT影像学中,从病灶分布来看,病例组的病灶分布在下叶的病例比例高于对照组（P<0.05）,病灶分布在上叶的病例比例低于对照组（P<0.05）;从形态上看,病例组中表现为网状病灶、间质性肺炎的比例高于对照组（P<0.05）,病例组中表现为空洞、纤维条索、实性影、结节影、树芽征、肺门淋巴结肿大的比例低于对照组（P<0.05）,而性别、合并免疫力低下疾病、咳嗽、咳痰、发热、咳血、关节痛、腹泻等在组间比较差异均无统计学意义。病例组全部病例的肺泡灌洗液宏基因测序结果显示：惠普尔养障体是唯一菌19例（95.0%）或主要菌1例（5.00%,合并结核菌1序列）,而对照组肺泡灌洗液宏基因测序结果显示：21例（37.5%）检测出结核分枝杆菌（TB）复合群是唯一菌或主要致病菌,18例TB-RNA（+）,15例TB-LAMP（+）。结论 惠普尔病在临床可表现为急性或亚急性病程,好发中老年男性,以发热和（或）呼吸道症状为主,可伴或不伴有腹泻、关节痛;肺部影像学以下肺网状、间质性肺炎改变为主,可以单独累及肺部;与初治菌阴肺结核患者临床症状极其相似。应尽快完善支气管镜检查,肺泡灌洗液的宏基因检测对早期、快速诊断此病尤为重要。

Objective To analyze and compare the clinical features of patients with pulmonary involvement of Whipple disease and primary treated bacteriological negative pulmonary tuberculosis,so as to improve the recognition,diagnosis and differentiation ability of pulmonary involvement of Whipple disease．Methods Clinical features of Whipple disease with pulmonary involvement were investigated by retrospectively collecting 20 cases as a case group,comparing with 56 randomly selected patients with primary treated bacteriological negative pulmonary tuberculosis as a control group during the same period．Results The case group had a significantly higher proportion of older patients（>37 years）,acute or subacute disease courses than the control group （P<0.05）．On CT imaging,in terms of lesion distribution,the proportion of cases with lesions in the lower lobe was significantly more in the case group than in the control group（P<0.05）,and the ratio of cases with lesions in the upper lobe was considerably less than in the control group（P<0.05）．Regarding morphology,significantly more of the case group showed reticular lesions and interstitial pneumonia than the control group（P<0.05）．Significantly fewer of the case group showed cavities,fibrous bands,solid shadows,nodular shadows,tree-bud signs,and enlarged hilar lymph nodes than the control group（P<0.05）．No statistically significant differences existed between the two groups in gender,combined immunocompromising diseases,cough,sputum,fever,coughing up blood,arthralgia or diarrhea. At the same time,the differences of gender,combined immunocompromised disease,cough,sputum,fever,coughing up blood,arthralgia,and diarrhea were not statistically significant．The metagenomic sequencing of alveolar lavage fluid in the case group revealed Tropheryma whipplei as the sole pathogenic bacteria in 19 cases（95%）or the primary pathogenic bacteria in 1 case（5.00%,combined TB 1 sequence）．In contrast,metagenomic sequencing of alveolar lavage fluid in the control group detected Mycobacterium tuberculosis complex as the sole or primary pathogenic bacteria in 21 cases（37.5%）,TB-RNA（+）in 18 cases and TB-LAMP（+）in 15 cases．Conclusions Clinical presentation in Whipple disease can be of an acute or subacute course,preferably in middle-aged and older men,with fever or/and respiratory symptoms,either with or without diarrhea and arthralgia．Its pulmonary imaging dominates with reticular,interstitial pneumonia changes in the lower lungs,which can involve the lungs alone in the disease．At the same time,the clinical symptoms are highly similar to those patients with primary treated bacteriological negative pulmonary tuberculosis．Therefore,it is vital to complete bronchoscopy and metagenomic sequencing of alveolar lavage fluid as soon as possible for early and rapid diagnosis of this Whipple disease．Treatment with sensitive antibacterial drugs can result in significant improvement and save patients' lives．
