目的观察感染1型艾滋病病毒感染儿童应用高效抗反转录酶疗法治疗过程产生耐药后,行病毒基因型耐药检测对选择新治疗方案的作用。方法对各种治疗失败的艾滋病病例检测与病毒耐药显著相关的病毒反转录酶氨基酸排列突变点位,显示耐药情况。结果艾滋病40例采用一线药物治疗失败。其中14例(35%)出现对核苷类反转录酶抑制剂中原组合应用的齐多夫啶与拉米夫啶同时耐药,26例(65%)对齐多夫啶与拉米夫啶中一种耐药,原核苷类反转录酶抑制剂至少其中的一种仍可应用于新药组合中。对于非核苷类反转录酶抑制剂,11例(27%)对耐韦拉平耐药,29例(63%)对耐韦拉平与艾非那韦同时耐药。5例二线药物治疗失败中,2例中耐药检测结果显示在一、二线药物中各有一药未出现耐药,可在新药物组合中应用。结论基因型耐药检测技术的应用对选择最好的个性化的艾滋病治疗方案有重要意义。 相似文献

We have studied sera from 44 children with Human Immunodeficiency Virus infection and Acquired Immunodeficiency Syndrome using immunoblotting, radioimmunoassay, enzymoimmunoassay and indirect immunofluorescence. We have detected a low incidence of antinuclear (2.9%), anti-reticulin (2.9%) and anti-smooth muscle (14.7%) antibodies by indirect immunofluorescence. By enzymoimmunoassay we have detected anti-dsDNA (20.5%) and anti-ENA [anti-nRNP (61.3%), anti-Sm (29.5%), anti-Ro (47.7%) and anti-La (18.1%)] antibodies. Tests for anti-dsDNA by radioimmunoassay were negative, suggesting the presence of low-avidity anti-DNA antibodies. By immunoblotting we have detected anti-C (nRNP) (33.3%), anti-BB' (Sm) (33.3%), anti-Ro (60 KD) (4.5%) and anti-La (11.3%) antibodies. The presence of anti-Ro antibodies was associated with progressive neurological disease. Long-term follow-up studies with larger numbers of patients are necessary to evaluate the clinical significance of the presence of anti-dsDNA and anti-ENA antibodies in children infected with Human Immunodeficiency Virus. 相似文献

An adrenal gland leiomyoma was incidentally found at autopsy in a 2-year-old boy with acquired immunodeficiency syndrome (AIDS). Smooth muscle neoplasms have been described in pediatric AIDS and affect mainly the tracheobronchopulmonary, gastrointestinal, and hepatobiliary systems. An association between Epstein-Barr virus (EBV) and smooth muscle tumors in patients with AIDS has been described. This case is the first leiomyoma to be reported in the adrenal gland of a child with AIDS. EBV genome was demonstrated in the tumor by polymerase chain reaction. 相似文献

目的 观察人类免疫缺陷病毒(HIV)感染者或艾滋病(AIDS)患儿接受联合高效抗反转录病毒治疗(HAART)不良反应的发生情况.方法 71例经酶联免疫法初筛、Western blot法确诊HIV感染、以前未接受过HAART的儿童入选本前赡性队列研究.男49例(69.0%),女22例(31.0%);平均年龄9.2(2~16)岁.其中46例接受齐多夫定(AZT)加拉米夫定(3TC)加奈韦拉平(NVP)治疗,25例接受司他夫定(d4T)加3TC加NVP治疗,记录治疗开始6个月内的不良反应(包括恶心、呕吐、腹泻、腹痛等消化道症状,中性粒细胞、Hb 下降,转氨酶升高,皮疹,血淀粉酶升高等)发生率,并比较2种治疗方案的不良反应.结果 主要不良反应发生情况如下:消化道症状(包括恶心、呕吐、腹泻、腹痛)52例(73.2%)、Hb下降30例(42.3%)、中性粒细胞下降12例(16.9%)、ALT升高15例(21.1%)、皮疹10例(10.4%)和血清淀粉酶升高6例(8.5%),多为轻到中度.Hb下降的发生率AZT加3TC加NVP组(56.5%)显著高于d4T加3TC加NVP组(16.0%)(P=0.001).6例因不良反应而更改治疗方案,其中3例因AZT引起贫血改用d4T,1例因皮疹、2例因ALX升高将NVP改为依非韦仑(EFV).无患者因不良反应而停止HAART.结论 儿童AIDS的HAART近期不良反应较少,程度较轻,耐受性良好.AZT较d4T的骨髓抑制作用明显.实用儿科临床杂志,2009,24(10):780-782 相似文献

Thirty autopsies performed on infants and children with HIV infection and/or AIDS were reviewed for the presence and type of infection. Twenty-six (87%) demonstrated evidence of infection in addition to HIV at the time of postmortem examination. Pathogenic bacterial infections were the most frequently encountered, seen in 15 of the cases. Nine of the 15 (60%) were due to gram-negative rods, most commonly Pseudomonas aeruginosa. Infections with gram-negative organisms often involved multiple organ systems and were frequently undiagnosed both pre -and postmortem because of variability in culture results and difficulties in identification both clinically and in tissue sections. Discussion is presented of unusual staining characteristics and filamentous morphology found with these pathogens. Other pathogenic bacteria encountered were Klebsiella pneumoniae, Escherichia coli, Enterobacter sp., and Staphylococcus. Fungal infections due to Candida species were present in nine cases (31 %) but were invasive in only two of these. One instance of Aspergillus meningo-encephalitis was noted. Proven viral infections were present in five children (three cytomegalovirus, one herpes simplex, and one adenovirus). Pneumocystis carinii pneumonia was diagnosed in five of the patients (17%), and one instance of disseminated Mycobacterium avium-intracellulare was encountered. 相似文献

小儿慢性腹泻病的营养治疗 总被引:1,自引:0,他引:1
小儿慢性腹泻病(chronic diarrhea disease,CDD)是导致小儿营养不良的重要原因,而营养不良又常会加重CDD患儿病情,严重影响患儿生长发育,因此若想减轻或避免腹泻引起的营养不良和提高患儿生存质量,合理地作好CDD患儿营养治疗是非常必要和必须的。 相似文献
