A placebo-controlled trial of maintenance therapy with fluconazole after treatment of cryptococcal meningitis in the acquired immunodeficiency syndrome. California Collaborative Treatment Group

BACKGROUND AND METHODS. In patients with the acquired immunodeficiency syndrome (AIDS), the rate of relapse after primary treatment for cryptococcal meningitis remains high. We conducted a controlled, double-blind trial to evaluate the efficacy of maintenance therapy with fluconazole. At entry into the study, all participants had sterile cultures of cerebrospinal fluid, blood, and urine after following a standardized course of therapy for culture-proved cryptococcal meningitis. The patients were randomly assigned to take either fluconazole or placebo as maintenance therapy. The dose of fluconazole was 100 mg daily in the first phase of study and 200 mg daily in the second phase. RESULTS. Of 84 patients initially enrolled, 16 (19 percent) were found to have silent, persistent infection on the basis of cultures that became positive after entry into the study; 7 other patients were lost to follow-up shortly after entry. Of the remaining 61 patients, 10 of 27 assigned to placebo (37 percent) and 1 of 34 assigned to fluconazole (3 percent) had a recurrence of cryptococcal infection at any site (difference in risk, 34 percent; 95 percent confidence interval, 15 to 53). Of the 11 recurrent infections, 7 were detected in urine obtained after prostatic massage. There were four recurrent meningeal infections in the patients taking placebo, but none in those taking fluconazole (mean duration of follow-up, 164 days) (P = 0.03). In multivariate analyses, the best predictors of recurrence-free survival were fluconazole treatment (P = 0.02; relative hazard, 13.2), a lower serum cryptococcal-antigen titer (P = 0.05; relative hazard, 1.2), and more prolonged primary therapy with flucytosine (P = 0.09; relative hazard, 1.1). Survival and toxicity were similar in the two maintenance-treatment groups. CONCLUSIONS. In patients with AIDS, silent persistent infection is common after clinically successful treatment for cryptococcal meningitis. Maintenance therapy with fluconazole is highly effective in preventing recurrent cryptococcal infection.     

Skin Test Reactivity and Cellular Immune Responses to Mycobacterium avium Sensitin in AIDS Patients at Risk for Disseminated M. avium Infection

Skin tests and lymphocyte proliferation assays (LPA) were performed with Mycobacterium avium sensitin on patients with AIDS. Among 139 subjects, 13% had positive skin test results and 32% had positive LPA results. The LPA may be a more sensitive indicator of prior M. avium infection in this population.     

Neurocognitive functioning among HIV-positive adults in southern India

The validity of a comprehensive international neuropsychological (NP) test battery for detection of HIV-associated neurocognitive disorders (HAND) in a Tamil speaking southern Indian cohort (69 HIV+ and 67 HIV?) was explored. The prevalence of HAND was significantly higher in the HIV+ vs. HIV? group (33 vs.13%; p < 0.01). Impairment rates were highest in the motor and speed of information processing domains. An NP battery translated into Tamil appears to be a valid tool for assessing HAND because the prevalence it found of HAND in southern India is similar to that found elsewhere.     

普罗布考和抗氧化维生素不影响体外实验条件下内皮细胞的白细胞粘附

为探讨预防动脉粥样硬化的药物普罗布考,维生素C和维生素E是否抑制内皮细胞表面粘附分子表达和白细胞一内皮细胞的粘附,以及这种抑制是否通过影响核因子－kB的活性来实现的,在液体流动小室中进行细胞粘附实验。用ELISA方法测定内皮细胞粘附分子E－选择素的表达;用电泳迁移率分析测定内皮细胞核因子－kB的活性,经肿瘤坏死因子α刺激的内皮细胞核因子－B活性增加,粘附分子E－选择素的表达上调（是基础水平的3．5倍）,其表面HL60细胞的粘附增加（是基础水平的4－26倍）,而抗氧化剂PDTC使所有这些变化都受到抑制。PDTC浓度为18umol/L时对粘附分子E－选择素的表达呈最大半抑制;PDTC浓度为52umol/L时对内皮细胞表面HL60细胞的粘附呈最大半抑制,普罗布考,维生素C和维生素E对肿瘤坏死因子α诱导的粘附分子表达和HL60细胞与内皮细胞的粘附没有作用,对核因子－kB的活性没有影响,临床上常用的这三种抗氧化剂并未影响作为动脉粥样硬化始动机制之一的E－选择素介导的白细胞－内皮细胞粘附水平。     

Demand for post-qualifying professional education in the health care sector in England

The British National Health Service is proposing to establish local consortia for educational contracting, with the wider involvement and responsibility being devolved to service providers This paper addresses the economic considerations of purchasing post-qualifying professional education in the English hospital sector, for hospital nurses, doctors and physiotherapists in England     

Wrist fracture, heel bone density and thoracic kyphosis: a case control study

The heel bone density measured by Broadband Ultrasound Attenuation (BUA), the thoracic kyphosis measured by a Kyphometer, height, and weight were compared between 294 women over 49 years of age who sustained a wrist fracture and 294 age-matched women who had not previous wrist, hip or spine fracture. The BUA was significantly less in the women who had wrist fracture (p less than 0.0005), though there was a considerable overlap between the two populations. The women with wrist fracture had significantly greater thoracic kyphosis (p less than 0.0005) and smaller stature (p less than 0.0005). There was no significant difference in weight. There was a significant tendency (p less than 0.0005) for women in the fracture patient group to have both poor BUA and greater kyphosis.
