RESUMO
Objective: HBV-related acute-on-chronic liver failure (HBV-ACLF) has a high mortality due to severe intrahepatic cholestasis and coagulation dysfunction, thus new treatment measures are urgently needed to improve the therapeutic effect. This study aimed to observe the efficacy of N-acetylcysteine (NAC) in the treatment of HBV-ACLF. Methods: The data of patients with HBV-ACLF admitted to West China Hospital from October 2019 to August 2020 were collected retrospectively, and they were divided into treatment group and control group according to whether they had received additional NAC treatment. The improvement of biochemistry, coagulation function and disease severity score after 14 days of hospitalization were analyzed between two groups. Results: A total of 90 HBV-ACLF patients were included, including 42 patients in treatment group and 48 patients in control group. Compared with baseline, serum TBil, DBil, TBA, GGT and ALP in two groups both decreased significantly, while PTA increased significantly. Interesting, the decrease of serum TBil, DBil and TBA and the increase of PTA in treatment group were all significantly than these in control group. Additionally, more patients in treatment group than control group changed from CTP grade C to grade B. Subgroup analysis of CTP grade C patients showed that the decrease of serum TBil, DBil and TBA and the increase of PTA in treatment group were significantly than these in control group. Conclusion: The NAC treatment may help to improve intrahepatic cholestasis and coagulation dysfunction of HBV-ACLF.
RESUMO
INTRODUCTION: Syphilitic aortic aneurysm (SAA) is caused by tertiary stage of syphilis infection. As the wide application of penicillin, this complication is becoming rarer than before. The SAA with lung cancer is a very rare disease in patient. CASE DESCRIPTION: A 55-year-old male was admitted to the hospital complaining "progressive hoarseness for 3 months" and the patient has been diagnosed with syphilis after specific blood exams, computed tomography angiography (CTA) and 3dimensional (3D) reconstructions of cardiac vessels. Chest computed tomography displayed an anomalous soft tissue mass with slightly lobular borders in the peripheral segment of the left lower lobe. According to the aneurysm's and lung neoplasm's location, several procedures could be selected such as aneurysm resection with artificial graft replacement or endovascular stenting under angiography. Then, the lesion was removed by lobectomy using video-assisted thoracic surgery. DISCUSSION AND EVALUATION: Cardiovascular syphilis remains a major cause of ascending aortic aneurysm. The clinical manifestations of patients with syphilis aortic aneurysm could vary. Aortic imaging is necessary to confirm the diagnosis and to determine the anatomic extent of the aneurysm. The differential diagnosis of the lesion in the pulmonary is mostly the tumor like pulmonary lesion, Pulmonary syphilis. Some studies showed that thoracic aortic aneurysm has been reduced by using penicillin. However, penicillin therapy alone is not always sufficient in recent years. The serologic response to treatment is more significant and faster in patients treated with the enhanced regimen compared to patients treated with the standard penicillin regimen. CONCLUSIONS: Syphilitic aortic aneurysm with lung cancer is a rare disease in patient. Chest CT and CTA scans are able to indicate the presence of SAA. Pathological analysis is an effective method to clarify the diagnosis of the lung lesion. The interventional therapy and surgery are regular treatment method for SAA and pulmonary neoplasm.
