Climatic factors and Pneumocystis jiroveci infection in southern Spain

The modes of infection and transmission of Pneumocystis jiroveci remain unclear. This study explored the relationship between the incidence of infection and climatic factors. In total, 536 cases of P. jiroveci infection were identified in the period 1994-1998, with an inverse correlation between the incidence of Pneumocystis pneumonia and the minimum mean ambient temperature (Spearman correlation coefficient: r - 0.30; p 0.02; ARIMA model: r - 0.250, p 0.07). The highest number of cases occurred in winter (anova test, p < 0.05), and there was a clear season-related incidence of P. jiroveci infection.     

中西医结合早期干预对SARS肺部炎症的影响

[目的]以X线胸片为主要观察指标,对中西医结合治疗SARS的临床疗效进行客观评价,为SARS临床筛选有效的干预方案提出科学依据。[方法]采用多中心前瞻性队列研究的方法,通过对参加国家863重大项目“中医结合治疗SARS临床研究”的北京地区11家医院361例确诊SARS患者的1561张X线胸片的研究,阐明中西医结合治疗对SARS肺部炎症的影响。[结果]从总体疗效来看,X线胸片总积分西医组平均为5.85±6.5。中西医结合组为6.67±7.61;普通型西医组为4.79±5.6。中西医结合组为5.40±6.86;重型西医组为7.67±6.34,中西医结合组为8.16±7.60,以上两组间比较均未见显著性差异 (P>0.05)。但发病7d内开始干预的胸片总积分西医组平均为6.39±6.48、中西医结合组为4.40±4.97,中西医结合组X线胸片总积分明显低于西医组 (P=0.0004);普通型西医组为4.59±5.22、中西医结合组为3.99±4.67,两组间比较未见显著性差异 (P=0.12);重型西医组为9.14±7.24、中西医结合组为5.30±5.48,组胸片总积分明显低于西医组(P=0.034);说 明发病7 d内对SARS患者进行中西医结合治疗,肺部炎症的吸收明显优于西医组,总体疗效与重型患者的疗效均具有统计学意义。[结论]中西医结合早期干预对SARS肺部炎症吸收的临床疗效具有明显的优势。     

SARS冠状病毒刺突蛋白编码基因及氨基酸序列的同源性分析

①目的 分析严重急性呼吸综合征(SARS)冠状病毒刺突蛋白(S蛋白)编码基因及氨基酸序列的变异情况，并在GenBank中寻找其同源序列。②方法 将网上公布的具有全基因序列的12株SARS冠状病毒S蛋白的编码基因序列及氨基酸序列应用Clustal W方法对排分析变异情况，并应用GenBank的Blast对排功能寻找被GenBank收录的同源序列。③结果 SARS冠状病毒S蛋白相对比较保守，变异率较低，其氨基酸序列与鼠的肝炎病毒氨基酸序列有较高的同源性，某些核苷酸序列与人的基因组有同源性。④结论 S蛋白编码基因及氨基酸序列相对保守，为预防性疫苗的研发提供了可行性；据其同源基因及蛋白序列可以预测S蛋白的二、三级结构，对推测SARS可能的发病机制有积极作用。

Indium-111 labelled pooled human immunoglobulin imaging to monitor the efficacy of specific therapy for Pneumocystis carinii pneumonia

Functional imaging is ideally suited to monitoring the effect of specific therapy on disease processes. In this pilot study five patients with AIDS and Pneumocystis carinii pneumonia (PCP) were imaged with Indium-111 labelled pooled human immunoglobulin (111In-HIG) during infection and after therapy for PCP. The lung activity of t t tln-HIG, measured as a lung/heart ratio, was calculated in a study performed during infection with PCP and after therapy. In all five patients the lung/heart ratio of t t 1ln-HIG was reduced after treatment. The mean reduction in heart/lung ratio was 27% (range 12%-53%). If these results are confirmed by a larger study, ¹¹In-HIG will be useful in monitoring the response of PCP to therapy in patients with AIDS.     

Coexisting Endogenous and Exogenous Llpold Pneumonia and Pulmonary Alveolar Proteinosis in a Patient with Neurodevelopmental Disease

We report a unique case of coexistingexogenous lipoid pneumonia, endogenous lipoid pneumonia (EU), and pulmonary alveolar proteinosis (PAP) in a 5-year-old patient with severe neurodevelop mental disease. The patient presented with gastroesophageal reflux and presumed chronic lung disease resulting from recurrent aspiration pneumonias and succumbed to respiratory failure. The autopsy showed lipid-laden macrophages and periodic acid-SchiJf9ositive granular matm'al i n alveolar spaces and multilamellated structures within both alveolar macrophages and extracellular debris.

These findings were similar to those in previous reports of coexisting E I P and PAP in the setting of gastroesophageal refux [I] . However, the present case diJfered by the presence of scattered large osmiophilic extracellular lipid vacuob. Besides strengthening the association between EIP and PAP and their relationship to gastroesophageal refux, this case suggests that t h q may arise together with exogenous lipoid pneumonia, through related mechanisms, in the setting of neurodevelopmental disease.
