背景:苏丹喀土穆、红海、加达里夫、卡萨拉、杰贝勒河、吉齐拉和北科尔多凡的卫生部门。 目的:为了研究结核病人表现的症状和临床史与涂片阳性程度之间的关系。 方法:5338名结核病可疑者,年龄从15岁到49岁,1998年3月至1999年3月间就诊者。他们均经过痰涂片镜检,并具有根据标准方法分级的痰涂片结果。经过个人同意,对患者进行一个经过构建的关于他们症状的初始情况及所持续时间和家中是否有病属的访问。统计学分析确定症状和家庭特征与涂片检测结果之间存在的关系。 结果:共有514名可疑者(9.6％)被检出抗酸杆菌:+1的45人(8.8％),+2的167人(32.5％),+3的302人(58.8％),绝大多数病人症状期为6-9周,而有100人超过一年,他们中的许多人(47人)伴有其他慢性呼吸系统病。多数胸部症状与痰涂片阳性程度相关,而与症状持续时间无关(P值分别为P=0.018,P=0.028)。那些症状持续时间少于一年者中,痰涂片阳性度高(+3),症状持续时间最长,是家中有病属的明显标志。(OR=1.99,95％CI 1.12-3.55,OR=1.004,95％CI 1.000-1.008) 结论:本研究表明痰涂片阳性程度与结核病人临床特点之间存在关系。
Background: Health departments in Khartoum, the Red Sea, Gadarifu, Kassala, Jebel, Sudila and Kitakordur in Sudan. Purpose: To study the relationship between symptoms and clinical history of tuberculosis patients and the positiveness of smear. Methods: 5338 suspicious TB patients aged from 15 to 49 years of age, March 1998 to March 1999 treatment. They were both sputum smear microscopy and had sputum smear results according to standard methods. With personal consent, patients are given a structured initial visit to their symptoms and their duration and presence of a family affiliation. Statistical analysis determined the relationship between symptoms and family characteristics and smear test results. RESULTS: A total of 514 suspicious individuals (9.6%) were detected for acid-fast bacilli: 45 (8.8%) at +1, 167 (32.5%) at +2 and 302 (58.8%) at +3, Most patients have symptoms for 6-9 weeks, while 100 have been older than a year, many of whom (47) have other chronic respiratory diseases. The majority of chest symptoms were related to the positive sputum smear but not to the duration of symptoms (P = 0.018, P = 0.028, respectively). Those with symptoms lasting less than one year had a high positive sputum smear (+3) and the longest duration of symptoms, a clear hallmark of disease at home. (OR = 1.99, 95% CI 1.12-3.55, OR = 1.004, 95% CI 1.000-1.008). CONCLUSIONS: This study shows that there is a relationship between the positive sputum smear level and the clinical features of TB patients.
