Soluble CD14 at 2 yr of age: Gender-related effects of tobacco smoke exposure, recurrent infections and atopic diseases

The endotoxin receptor soluble CD14 (sCD14) has been implicated in the 'hygiene hypothesis' suggesting reduced allergic sensitization with bacterial stimulation. However, the relationship between early life sCD14 and allergic diseases is conflicting. We aimed to investigate whether possible risk factors for allergic diseases were associated with sCD14 levels at 2 yr of age. In the nested case-control study of the birth cohort studies 'Environment and Childhood Asthma study in Oslo' 411 children selected with recurrent bronchial obstruction (rBO) (n=241) and no bronchial obstruction (n=170) by 2 yr were investigated with skin prick test and structured parental interview at age 2 yr. Exposure to tobacco smoke, pets and infections was recorded semi-annually by questionnaires (0-2 yr). The sCD14 was analysed from frozen, stored serum by ELISA technique. Regression analyses were performed in all subjects with complete data (n=406, 180 girls), and in girls and in boys separately. Mean sCD14 (ng/ml) was significantly higher among girls 2035 (1973-2096) vs. 1947 (1890-2004) (boys). The sCD14 was significantly reduced among girls exposed to antenatal maternal smoking and with parental asthma, after adjusting for age, parental rhino-conjunctivitis, pet keeping and childhood infections. Recurrent otitis media (OM) increased and common colds significantly decreased sCD14 levels in girls. Boys with atopic dermatitis and rBO had reduced sCD14. Pet exposure was not significantly associated with sCD14. We report novel gender-related effects of sCD14 in early life and suggest that gender, tobacco smoke exposure, age and middle ear disease in particular should be accounted for when assessing the role of sCD14 in childhood allergic diseases.

Prosthetic joint infectionsin the elderly

Total joint arthroplasty is among the most remarkable advances in orthopaedic surgery for the elderly, enabling themto regain physical function and be free of pain. Although uncommon, infection of the prosthetic joint causes serious morbidity leading to poor functional outcome with a mortality approaching 8% in the elderly. Most infections occur through inoculation of the prosthesis at the time of implantation and are due to Gram-positive cocci, although a third of the episodes are due to Gram-negative bacilli from a secondary focus. The management presents a major clinical and therapeutic challenge due to systemic and local comorbid conditions in the elderly. Medical and surgical treatment decisions for infected joint prosthesis are complex and should be individualized in each case. Optimal nutrition is essential for a successful outcome. Adverse reactions to medications are more common in the elderly due to end organ dysfunction and drug-drug interactions.     

Adhesins of uropathogenic bacteria: Properties,identification and use for new antibacterial strategies

Adherence is a major virulence factor in the complex pathogenesis of urinary tract infections (UTI). Colonization of the urinary tract and subsequent spread of infection ascending to the kidneys depends not only on the expression of adhesins by bacteria but also on the presence of host factors which may either contribute to or inhibit infection. The presence of certain types of adhesins expressed by the bacteria and their interactions with epithelial cells play a role in determining where bacteria localize in the urinary tract, the kind and severity of symptoms and how the disease progresses. The knowledge of the molecular mechanisms underlying adherence may be useful for epidemiological research in the pathogenesis of UTI, for the diagnosis of different types of UTI and, in some cases, for prognosis. Furthermore, attachment to epithelia is a promising target for developing new methods in prophylaxis and therapy.     

长春地区儿童急性呼吸道感染的病原趋势

目的:探讨北方地区小儿急性呼吸道感染(ARIs)病原构成特点,为临床诊断及治疗提供依据。方法:采用酶联免疫吸附试验(ELISA)方法,对574例ARIs患儿进行了肺炎支原体(Mp)、沙眼衣原体(CT)、肺炎支原体(CP)、呼吸道合胞病毒(RSV)、腺病毒(Adv)、流感病毒A型(Inf-A)、副流感病毒(PIV)等7种病原同步进行急性期血清特异性抗体IgM检测,同时设立健康对照组。结果:574例患儿共334例检出特异性IgM抗体,阳性率58.2%。按检出频率的高低依次为Mp28.9%(166/574),RSV13.6%(78/574),CP5.9%(34/574),CT4.4%(25/574),Adv3.3%(19/574),Inf-A1.2%(7/574),PIV0.9%(5/574),分别占阳性例数的49.7%(166/334)、23.3%(78/334)、10.2%(34/334)、7.5%(25/334)、5.7%(19/334)、2.1%(7/334)和1.5%(5/334);病原分布具有年龄差别。健康对照组仅检出1例MP-IgM阳性(1.7%)。结论:Mp、RSV及CT为小儿ARI的常见病原。Mp感染率逐渐增高,发病年龄有逐渐变小的趋势。     

Erythema multiforme during cytomegalovirus infection and oral therapy with terbinafine: a virus–drug interaction

The authors report a case of erythema multiforme in a 32-year-old woman who was also taking oral terbinafine for an onychomycosis. The patient data analysis showed serological positivity for cytomegalovirus (IgM and IgG) and hepatitis C virus and serological titre of antinuclear antibody was elevated. After a brief review of the literature the authors propose the possibility of virus-drug interaction as a model of adverse drug reactions.
