登革热是经蚊传播,由病毒引起的急性发热性疾病,典型症状及体征为头痛、发热,肌痛、关节痛、恶心、呕吐、向心性皮疹,有些患者有鼻衄、阴道出血、柏油便,大多在7～10天时恢复。休克及出血为主要死亡原因。仅少数报道有胃肠道出血。本文对26例经血清学及病毒学证实的登革热患者,分析其内镜及上消化道改变。病人和方法从1987年12月～1988年12月,共198例登革热患者,其急性期及恢复期配对血清滴度增高4倍以上为阳性。用血凝抑制法测抗体滴度。单份血标本则滴度>1:320为阳性。将急性病毒血症期的血作病毒分离,并作血清学及病毒学检测。对其中26例并发上消化道出血者均用 Olympus X Q_(10)全视式内
Dengue fever is mosquito-borne, caused by the virus of the acute febrile illness, the typical symptoms and signs of headache, fever, myalgia, joint pain, nausea, vomiting, concentric rash, and some patients have epistaxis, vaginal bleeding, Mostly restored in 7 to 10 days. Shock and bleeding as the main cause of death. Only a few reported gastrointestinal bleeding. In this paper, 26 cases of dengue fever confirmed by serological and virological analysis of endoscopic and upper gastrointestinal changes. Patients and Methods From December 1987 to December 1988 a total of 198 cases of dengue fever patients, the acute and convalescent paired serum titer increased more than 4 times as positive. Antibody titers were measured using hemagglutination inhibition. Single copies of blood samples titer> 1: 320 is positive. The acute viremia blood for virus separation, and for serological and virological testing. In 26 cases of patients with upper gastrointestinal bleeding were Olympus X Q_ (10) full-view
