Oral tuberculosis associated with a treatment with anti-rheumatic drugs

BACKGROUND: The use of immunosuppressive medication is a dominant risk factor for infection in patients with rheumatoid arthritis (RA). Methotrexate (MTX) is one of the traditional disease-modifying antirheumatic drugs. Adalimumab [a human anti-tumor necrosis factor-alpha (anti-TNF-alpha) monoclonal antibody] represent an important advance in the treatment of RA and has been recently come in use. TNF-alpha plays a role in the host defense against Mycobacterium tuberculosis and notably in granuloma formation. Infections occur at a high rate among those who use one or the combination of the two medications. METHOD: We examined a female patient that was referred to our department for evaluation and treatment of a granular lesion on the soft palate and uvula, complaining of mild dysphagia. The patient was treated for 4 months with MTX and adalimumab for RA before the oral lesion appeared. RESULTS: The histopathological examination of a specimen of the oral lesion, taken by biopsy, showed a chronic inflammation characterized by tuberculous granulomas. Polymerase chain reaction test and culture of a new specimen was positive for M. tuberculosis. CONCLUSIONS: The therapeutic use of MTX or/and adalimumab for the treatment of RA or few others diseases, can cause oral tuberculosis.     

Perception and social consequences of tuberculosis: A focus group study of tuberculosis patients in Sialkot, Pakistan

Treatment defaulting is one of the major causes of the failure of TB control programs. In Bethania Hospital. Sialkot, defaulting rates are high: 72% for the standard 12 months course and 56% for the 8 months course. Attrition is especially important in the first weeks of treatment: < 70% of the patients start the 10th week of treatment. A focus group discussion study has been carried out to gain a better understanding of the impact of social stigmatization, treatment cost and pregnancy on defaulting. The study population consisted of 3 male and 3 female groups each with 8 hospitalized TB patients. The study shows that TB is perceived as a very dangerous, infectious and incurable disease. This perception has many social consequences: stigmatization and social isolation of TB patients and their families; diminished marriage prospects for young TB patients, and even for their family members; TB in one of the partners may lead to divorce. Due to fear patients often deny the diagnosis and reject the treatment. While both male and female TB patients face many social and economical problems, female patients are more affected. Divorce and broken engagements seem to occur more often in female patients. Females are usually economically dependent on their husbands and family in law, and need their cooperation to avail of treatment. The belief that pregnancy enhances the risk for relapse decreases their marriage prospects. Pregnancy is also a reason for stopping TB treatment as both are considered as incompatible. The findings of this study reveal the urgent need for a health education campaign to convince the general population that tuberculosis is curable. All health care providers should act as destigmatizers.     

用聚合酶链反应技术诊断结核病

用聚合酶链反应技术对结核杆菌特异性重复序列ＩＳ６１１０部分基因１２３ｂＰ的片段进行扩增。该法检测人型结核杆菌灵敏度可达到１０ｆｇＤＮＡ，对１４９份结核患者临床标本检测结果显示ＰＣＲ总阳性率（６９．１％）明显高于直接涂片荧光镜检（１５．４％）与细菌培养（１０．１％）的阳性率（Ｐ＜０．０１）。研究表明ＰＣＲ是一种特异、敏感、快速诊断结核病的好方法，值得推广。

目的:探讨肝硬化病人发热原因。方法:对组织学和临床诊断的肝硬化发热病人进行回顾性分析。结果:421例肝硬化病人中,172例伴发热,占40.9％。以各种感染为最多,共75例(43.6％),其他原因主要有结核性腹膜炎、慢性活动性肝炎、合并肝癌或其他癌症,消化道出血和未明原因发热(21例、12.2％)。住院期间死亡48例,同期住院不发热的肝硬化249例中死亡41例。结论:肝硬化病人发热原因较多,其中以感染最为常见,伴发热的肝硬化病人预后更差。     

结核分枝杆菌Ag85B/GST融合蛋白表达载体构建及在大肠杆菌中的表达

目的 构建结核分枝杆菌Ag85B／GSF融合蛋白表达质粒，并在大肠杆菌(E．coli)中诱导表达。方法 以质粒pUC18／Ag85B为模板，用PCR法扩增结核杆菌Ag85B基因，扩增的Ag85B上游含有EcoR Ⅰ酶切位点，下游含有SalⅠ酶切位点；将Ag85B基因定向插入质粒pGEX-4T-1中，构建原核表达质粒pGEX-Ag85B并转化E．coli B121，筛选阳性重组子，限制性内切酶切鉴定和DNA序列测定，异丙基硫代半乳糖苷(IPTG)诱导表达，SDS-PAGE和Westem blot鉴定结果。结果 成功构建原核表达质粒pGEX-Ag85B并表达出Mr约56000大小的Ag85B／GSY融合蛋白，表达量占总菌体的30％。结论 为进一步进行纯化Ag85B蛋白和研究其在膀胱肿瘤治疗中的作用奠定了基础。     

抗结核药物所致皮疹临床特点及停药指征的探讨

目的 探讨抗结核药物所致皮疹的临床特点及停药指征.方法 对1998-2005年收治的3 082例住院结核病人中,因抗结核药物所致皮疹296例病人进行分析.结果 变态反应总发生率为10.3%,皮疹发生率为9.6%（296例）,其中单纯皮疹88例,占2.9%,皮疹伴其他系统表现一种或一种以上者208例,占6.7%;无皮疹者22例,占0.7%.皮疹病例总停药率为61.5%.结论 抗结核药物所致过敏反应多为全身性,发生过敏反应后,绝大多数单纯皮疹病人经过抗过敏处理后仍可维持原方案继续治疗,而皮疹伴有明显肝功能异常、心律失常、关节痛和过敏性休克者均需立即停用抗结核药物,并且避免再次使用.
