    acometimento ocular nos indica que a conjuntivite alérgica nada mais é que uma das formas de expressão da atopia, assim como são a rinite, a bronquite e a dermatite.PURPOSE: To study the response to skin prick tests in patients with vernal keratoconjunctivitis and compare with the allergic population without ocular disease. METHODS: We performed skin prick tests in 48 patients with VKC (10 with limbal form, 19 with palpebral and 19 with both. Controls were 52 patients from Allergy Clinic of the Santa Casa de São Paulo, with systemic allergy but without ocular disease. Skin prick tests were performed in 48 patients from the Ocular Allergy Sector at the Ophthalmology Department of the Santa Casa de São Paulo's Hospital, from July 2001 to September 2002. We studied responses to the following allergens: house dust mite, Dermatophagoides pteronissynus, Dermatophagoides farinae, Tyrophagus putrescentiae, Blomia tropicalis, Rhizopus spp, Penicilium, Alternaria alternata and rye grass. RESULTS: Male sex was the most frequent, with 32 patients (66.6% in the study group, and 27 (51.9% in controls. Mean age was 10.0 ± 4.7 years in the study group and 6.83 ± 3.6 in controls. The most frequent allergen was Dermatophagoides pteronissynus, followed by Dermatophagoides farinae, Blomia tropicalis, house dust mite, Tyrophagus putrescentiae and Rhizopus spp. CONCLUSIONS: The resemblance of the results in the control group indicates that allergic conjunctivitis is nothing else but another form of atopy, just as rhinitis, bronchitis and dermatitis.

    Phlyctenular keratoconjunctivitis, a delayed hypersensitivity reaction to foreign proteins (i.e., bacterial products), occurs more often in children and young adults sensitized to Staphylococcus aureus inhabiting the lid margins. Clinical manifestations occur on the conjunctiva and/or the cornea. Management strategies used to treat a 14-year-old girl with a long history of keratoconjunctivitis with severe corneal involvement and secondary lacrimal gland enlargement included a complete ocular examination, blood workups, cultures, vigorous lid hygiene, topical antibiotics and steroids, and systemic doxycycline. Phlyctenular keratoconjunctivitis was diagnosed, and Streptoccocus viridans was found colonizing the lid margins and fornices. Subsequent treatment quieted the active inflammation and the secondary lacrimal gland enlargement. However, the residual corneal scarring permanently compromised visual acuity. This patient demonstrates the potentially blinding consequences of untreated phlyctenular keratoconjunctivitis. Moreover, Streptoccocus viridans is not frequently associated with this disorder. To our knowledge hypertrophy of the lacrimal gland, as a secondary complication of this disorder, has not been reported previously. PMID:22827417

    Objective To describe the ocular complications of 62 patients with active atopic dermatitis( AD) during the period of 2003 2006. Methods Routine ophthalmic examinations, including slit-lamp microscope, indirect ophthalmoscope or Goldmann three-mirror lens, A-scan and B-scan ultrasound, ultrasound biomicroscope (UBM) and corneal topography, as well as tear film break-up time (BUT) and Schirmer tests were carried out. Results Cataract (28 eyes), keratoconjunctivitis (42 eyes), superficial punctate keratopathy (45 eyes) and tear function abnormality ( 76 eyes) were major ocular complications in AD patients. Retinal detachment (6 eyes) was the most severe ocular complication in the AD patients. Conclusion Ocular complications are common in AD patients and a very careful examination of eyes is essential in treating AD patients. If the eyes can be examed carefully and in time, some operations and severe complications can be avoidable, especially for the patients with retinal breaks or retinal detachment.

    Infectious conjunctivitis is a very common presentation to medical professional and ophthalmologist all over the world. Although its typically self-limiting and treatable in almost all of the cases, but we need to be aware of the rare and potentially life threatening if the cause is not promptly identified and treated accordingly. In our case report, we highlighted the rare case of Neisseria meningitidis as a primary cause of keratoconjunctivitis. Neisseria meningitidis is a rare etiology of keratoconjunctivitis and its ocular presentations are quite similar with other bacterial or viral infection. The infection may potentially fatal if systemic invasion occurred, however with immediate and proper treatment the outcome is satisfactory. Early diagnosis and proper antibiotic treatment are critical to prevent systemic spread of the infection. Public health intervention is needed to prevent outbreak of the disease.

    Full Text Available Abstract Atopic dermatitis (AD is a common, chronic skin disorder that can significantly impact the quality of life of affected individuals as well as their families. Although the pathogenesis of the disorder is not completely understood, it appears to result from the complex interplay between defects in skin barrier function, environmental and infectious agents, and immune abnormalities. There are no specific diagnostic tests for AD; therefore, the diagnosis is based on specific clinical criteria that take into account the patient’s history and clinical manifestations. Successful management of the disorder requires a multifaceted approach that involves education, optimal skin care practices, anti-inflammatory treatment with topical corticosteroids and/or topical calcineurin inhibitors (TCIs, the use of first-generation antihistamines to help manage sleep disturbances, and the treatment of skin infections. Systemic corticosteroids may also be used, but are generally reserved for the acute treatment of severe flare-ups. Topical corticosteroids are the first-line pharmacologic treatments for AD, and evidence suggests that these agents may also be beneficial for the prophylaxis of disease flare-ups. Although the prognosis for patients with AD is generally favourable, those patients with severe, widespread disease and concomitant atopic conditions, such as asthma and allergic rhinitis, are likely to experience poorer outcomes.

    Infectious bovine keratoconjunctivitis, also known as pinkeye, is an economically important disease in cattle. The objective of this study was to detect QTL associated with infectious bovine keratoconjunctivitis in offspring from a Brahman x Hereford sire. The sire was mated to Hereford, Angus, and F1 cows to produce 288 offspring in 1994 and mated to MARC III ((1/4) Hereford, (1/4) Angus, (1/4) Red Poll, and (1/4) Pinzgauer) cows in 1996 to produce 259 offspring (547 animals total). Infectious bovine keratoconjunctivitis was diagnosed by physical examination in 36 animals of the family. Records included unilateral and bilateral frequency, but not severity. Records were binary: 0 for unaffected and 1 for affected cattle. A putative QTL for infectious bovine keratoconjunctivitis was identified on chromosome 1, with a maximum F-statistic (F = 10.15; P = 0.0015) at centimorgan 79 of the linkage group. The support interval spanned centimorgans 66 to 110. There was also evidence suggesting the presence of a QTL for infectious bovine keratoconjunctivitis on chromosome 20, with a maximum F-statistic (F = 10.35; P = 0.0014) at centimorgan 16 of the linkage group. The support interval ranged from centimorgan 2 to 35. This report provides the initial evidence of QTL for infectious bovine keratoconjunctivitis. Although a candidate gene was identified for one of the regions of interest, further studies are needed to identify the genetic basis of resistance to the disease. PMID:17093209

    Full Text Available Objectives: Major objective is the evaluation of the medical effectiveness of different therapeutical approaches and the cost effectiveness with relevance for Germany. Methods: This health technology assessment (HTA evaluates systemically randomized controlled studies (RCT on the therapy of atopic dermatitis which were published between 1999 and 2004. Further it includes some important clinical studies which have been published after 2004 and other updates the English HTA report by Hoare et al. [1]. Results: Topical corticosteroids and topical calcineurin-inhibitors are the principal substances which are currently used for anti-inflammatory therapy in atopic dermatitis. These substances have shown a significant therapeutic efficacy in controlled studies. In newer controlled studies no difference was observable when corticosteroids were applied once or more than once daily onto the skin. Moreover, there is now one controlled study available which points to the fact that an interval therapy with a stronger topical corticosteroid over a limited time (some weeks may lower the risk of recurrent flares of atopic dermatitis. Both topical calcineurin-inhibitors pimecrolimus and tacrolimus have shown a significant therapeutical efficacy in a number of placebo-controlled prospective studies. The wealth of data is high for these substances. Both substances have been shown to be efficient in infants, children and adult patients with atopic dermatitis. The importance of a so-called basic therapy with emollients which have to be adapted to the current status of skin is generally accepted in clinical practice. Controlled studies show the efficacy of ”basic therapy” - although the level of evidence is quite low for this approach. The skin of patients with atopic dermatitis is colonized in the majority with Staphylococcus aureus, a gram-positive bacterium. Therefore, a therapeutical approach for the treatment of atopic dermatitis is the anti-bacterial or

    Poor corneal penetration and short residence time on the ocular surface are two major bottlenecks for conventional ophthalmic formulations. To overcome the foregoing dilemmas, we prepared two novel formulations of pimecrolimus nanomicelles (PNM) with particle size of 37.85 ± 1.21 nm and thermosensitive hydrogel (PTH) for treating Keratoconjunctivitis Sicca (KCS). PNM were investigated by transmission electron microscopy (TEM), Malvern laser particle size analyzer, X-ray diffraction (XRD) system, and the content of drug in PNM was measured by high-performance liquid chromatography (HPLC). The drug loading and encapsulation efficiency reached to 7.57% ± 0.10% and 97.9% ± 1.26%, respectively. PTH displayed special gel-sol transition behavior with temperature increasing from 4 °C to 37 °C. The in vitro release profile demonstrated that PNM and PTH exhibited sustained-release behavior compared with free pimecrolimus oil-based eye drop (FPO). In addition, we established a mouse model of KCS induced by benzalkonium chloride to evaluate the therapeutic outcome of different pimecrolimus formulations. The production of tear, fluorescein staining scores and histopathologic examinations of the cornea were assessed in detail. The results confirmed that PNM had the best therapeutic effect among all formulations based on its higher drug encapsulation capability, favourable permeability and sustained release. All these indicated that PNM could serve as a potent ophthalmologic agent for KCS. PMID:26731192

    Human adenoviruses are non-enveloped DNA viruses causing various infections; their pathogenicity varies dependent on virus species and type. Although acute infections can sometimes take severe courses, they are rarely fatal in immune-competent individuals. Adenoviral conjunctivitis and epidemic keratoconjunctivitis are hyperacute and highly contagious infections of the eye caused by human adenovirus types within species D. Currently there is no causal treatment available to counteract these diseases effectively. The E2B region of the adenovirus genome encodes for the viral DNA polymerase, which is required for adenoviral DNA replication. Here we propose novel model systems to test this viral key factor, DNA polymerase, as a putative target for the development of efficient antiviral therapy based on RNA interference. Using our model cell lines we found that different small interfering RNAs mediate significant suppression (up to 90%) of expression levels of viral DNA polymerase upon transfection. Moreover, permanent expression of short hairpin RNA based on the most effective small interfering RNA led to a highly significant, more than tenfold reduction in replication for different human group D adenoviruses involved in ocular infections.

Results: Six hundred and eighty eight studies were evaluated, 38 of which fulfilled the criteria for inclusion in the guidelines. Conclusions and Recommendations: Both UV1 and narrow-band UVB are effective in significantly decreasing the eczema severity although UV1 may be preferred in acute flares and narrow-band UVB in chronic eczema, especially in adults (Level of evidence 1+, Grade of recommendation A. Among various doses of UVA1, medium dose UVA1 may be preferred over others as its efficacy is similar to high dose and better than low dose UVA1 phototherapy. Narrow-band UVB is preferred to broad-band UVB (Level of evidence 1+, Grade of recommendation A. Medium-dose UVA1 is similar in efficacy to narrow-band UVB (Level of evidence 1+, Grade of recommendation A. In children, despite its efficacy, narrow-band UVB phototherapy should be used only as a second line therapy due to its potential for long-term adverse effects (Level of evidence 2+, Grade of recommendation B.

    Atopic dermatitis is a chronic inflammatory skin condition with drastic impacts on pediatric health. The pathogenesis of this common disease is not well understood, and the complex role of the skin microbiome in the pathogenesis and progression of atopic dermatitis is being elucidated. Skin commensal organisms promote normal immune system functions and prevent the colonization of pathogens. Alterations in the skin microbiome may lead to increased Staphylococcus aureus colonization and atopic dermatitis progression. Despite the evidence for their important role, probiotics have not been deemed efficacious for the treatment of atopic dermatitis, although studies suggest that probiotics may be effective at preventing the development of atopic dermatitis when given to young infants. This review will cover the most recent published work on the microbiome and pediatric atopic dermatitis. PMID:26388516

    A 12-year-old Pug presented with a 3-mm corneal mass OD. The dog was currently being treated for keratoconjunctivitis sicca (KCS) and pigmentary keratitis OU. A superficial keratectomy followed by cryotherapy was performed OD. A histopathologic diagnosis of epithelial dysplasia and suppurative keratitis was made and the lesion resolved. Two months later, a yellow/tan conjunctival mass, diffuse chemosis and conjunctival thickening was discovered OD. Necrotizing conjunctivitis with protozoal parasites was diagnosed with histopathology. Complete blood count and a serum biochemistry panel were normal. Neospora caninum and Toxoplasma gondii titers were negative. The conjunctivitis resolved after a 6-week course of oral clindamycin. Two months later, the patient presented with a similar conjunctival mass OS. Toxoplasma gondii was confirmed as the etiologic agent with immunohistochemical staining. Repeat T. gondii titers were negative. Oral clindamycin was re-instituted. The corneal biopsy was re-reviewed and protozoal organisms were discovered. Three months later, a recurrence was suspected and oral ponazuril was initiated for 28 days. There has been no evidence of recurrence since this treatment. Ocular toxoplasmosis is rare in the dog but reports have included episcleritis, scleritis, retinitis, anterior uveitis, ciliary epithelium hyperplasia, optic neuritis and polymyositis. To our knowledge, this is the first confirmed report of toxoplasmosis causing only corneal and conjunctival disease in the dog. We hypothesize that these localized lesions may be associated with topical immunomodulating therapy for KCS. Toxoplasmosis should be considered as a differential for canine conjunctivitis and corneal disease and has the potential to manifest in one or both eyes. PMID:19152600

    Full Text Available Aim: To determine the clinical features of vernal keratoconjunctivitis and to evaluate the safety and the efficacy of the medical treatment on clinical grades. Material and Method: All patients with vernal keratoconjunctivitis who had been treated with mast-cell stabilizers, antihistamines and artificial tear drops previously were enrolled in the study. Topical steroids were added during recurrences, were tapered and discontinued according to the clinical improvement. Topical cyclosporin 0.05% four times daily was used additionally in cases of inadequate response to treatment or evident steroid dependance. Main outcome measures were the clinical features, change of clinical grades, response to treatment, rate of recurrences and side effects of the eyedrops. Results: Twenty patients ( 13 males, 7 females with vernal keratoconjunctivitis in different severity scales were included. The median age of the patients was 10 (9-11 years. The median follow-up time was 35 (15-56 months. Ten patients received topical cyclosporine. The rate of recurrences was similar in patients who received topical cyclosporine compared to those who were followed with topical steroids. (p=0.17 No severe adverse reaction to any of the formulations was seen. Discussion: Topical 0.05% cyclosporin is safe and effective for the treatment of vernal keratoconjunctivitis as a steroid sparing agent. It helps to obtain good clinical response without serious adverse effects and provides improvement on the clinical grades.

    Phototherapy is a second-line treatment for moderate to severe atopic dermatitis (AD) that effectively decreases cutaneous inflammation with minimal or no systemic side effects. Children in grade school, adolescents, and adults may benefit from phototherapy, when they have chronic AD refractory to first-line topical treatments. This review focuses on six approaches for phototherapy in AD: (1) broadband ultraviolet B (UVB), (2) Goeckerman regimen (coal tar + broadband UVB), (3) narrowband UVB, (4) excimer lasers for targeted areas, (5) combination UVA/UVB, and (6) UVA-1. Phototherapy can be very effective in some individuals, but it is limited by inconvenience and adverse effects, including limited access to in-office treatment, difficulty adhering to thrice-weekly schedule, flaring from excessive heat, and increased risk of skin cancer. Dosing regimen and treatment concerns are reviewed. PMID:27638440

    Full Text Available Scleroderma is autoimmune connective tissue disorder which destroys healthy body tissues that causes widespread systemic and ocular features. A buildup of collagen in the skin and other organs leads to symptoms of the disease. It is of two types localized and diffuse. Systemic sclerosis has tendency to affect internal organs. It shows a non - mendelian pattern of inheritance with gene polymorphism. 1 Incidence of the disease is 9 - 19 cases per million 2 . Mortality is 30% with life threatening and visual threaten ing complications. 3 Occurrence of keratoconjunctivitis sicca in localized form of scleroderma is a quite a rare abnormality. We have presented a 38 year old female patient exhibiting characteristic features of localized scleroderma with keratoconjunctiviti s sicca and then the literature is reviewed.

    Full Text Available Atopic dermatitis (AD is a chronic inflammatory skin disorder that typically occurs during childhood especially in the first year of life, with a variable frequency from 10% to 30%. Recent studies have shown that in Europe among 10-20% of children with AD suffer from this disorder also in adolescence. AD is a chronic inflammatory skin disease with a typical onset in the first years of life and with a 10- 30% prevalence among young children. AD prevalence in adolescence has been estimated around 5-15% in European countries. AD persists from childhood through adolescence in around 40% of cases and some risk factors have been identified: female sex, sensitization to inhalant and food allergens, allergic asthma and/or rhinoconjunctivitis, the practice of certain jobs. During adolescence, AD mainly appears on the face and neck, often associated with overinfection by Malassezia, and on the palms and soles. AD persistence during adolescence is correlated with psychological diseases such as anxiety; moreover, adolescents affected by AD might have problems in the relationship with their peers. Stress and the psychological problems represent a serious burden for adolescents with AD and cause a significant worsening of the patients’ quality of life (QoL. The pharmacological treatment is similar to other age groups. Educational and psychological approaches should be considered in the most severe cases.

    Full Text Available The nervous system, the immune system, and the cutaneous system are not independent systems, but are closely associated and use the same language of cytokines and neurotransmitters. Atopic dermatitis (AD is exacerbated by several factors, such as emotional stress, scratching and sweating. This review presents the role of neuropeptides (NP in AD. In AD, abnormalities occur in distribution of some types of neural filaments and in the associated active NP. Nerve fibre increases. Nerve fibres for substance-P (SP and calcitonin gene-related peptide (CGRP are positive, The cutaneous concentration of SP decreases while vasoactive-intestinal polypeptide (VIP increases. Immunohistochemical examination has revealed neuropeptide-Y (NPY-positive dendritic epidermal cells in AD lesions but no somatostatin (SOM fibres. Neuromediators modulate functions of all cutaneous cellular types, which are all part of the neuroimmunocutaneous system (NCIS: endothelial cells, glandular cells, fibroblasts, epidermal cells and immune cells. Conclusion: during the course of AD, the NICS is destabilized. Evidence show that NP can also be responsible for the induction and maintenance of the cutaneous inflammation process and confirm an involvement in the pathogenesis of AD. Release of the NP by cutaneous nerve potentially explains the role of emotional stress, scratching and sweating in exacerbation of AD.

  8. Atopic Dermatitis and the Atopic March: What Is New?

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Results. Studies about atopic march are cross-sectional population studies at different ages. They show that the most important predisposing factor for atopy is a decrease of the filaggrin's expression. Conclusions. The most modern theories seem to show that the most important factor which starts the atopic march is represented by an impaired epidermal barrier. It causes an increase in skin permeability to allergens that could induce sensitization even in the airways. The major predisposing factor is a primary inherited epithelial barrier defect resulting from filaggrin gene mutation, but other factors may play a role in this complex mechanism. Further studies are needed to focus on AD treatment and preventive strategies.

  17. The Potential Therapeutic Effect of Green Tea in Treatment of Vernal Keratoconjunctivitis

    Directory of Open Access Journals (Sweden)

    Mahnaz Mosallaei

    2008-05-01

    Full Text Available Vernal keratoconjunctivitis is a chronic, recurrent and severe ocular allergic disease, which is characterized by persistent allergic inflammation of the conjunctiva. It can be accompanied by ocular discomfort and visual disturbance. All forms are characterized by intense itching, tearing, mucous secretions and a severe photophobia, which often forces children to live virtually in dark places. Conjunctival proliferative changes, such as the formation of giant papillae are the characteristic findings of affected individuals. Giant papillae develop as a result of infiltration of inflammatory cells, changes in the epithelial layer, and increased deposition of extracellular matrix molecules such as collagen and proliferation of conjunctival fibroblasts. Currently several therapeutic options such as corticosteroids, mast cell stabilizers and cyclosporine are applied for treatment of Vernal keratoconjunctivitis but in long-term, the chronic and recurrent nature of this problem leads to failure or appearance of side effects of current treatment in many patients. Recently, Green tea extract and its principal active ingredient, epigallocatechin gallate , are gaining attention and increased usage due to its healthful properties. It has considerable anticatactogenic effect by inducing apoptosis in lens epithelial cells and antioxidant effects. Also its great benefits were achieved in attenuation of damaging influences to the retina caused by ischemia/reperfusion. Based on evidences supported beneficial effects of green tea, we hypothesize that local administration of green tea and its extract seems to be a proper substitute or adjunct to current treatments of Vernal keratoconjunctivitis. This plant contains a series of antioxidants that can abolish the process of allergic cascade. Moreover, by suppressing TNF-alpha potentially, it can reduce proinflammatory reaction, as well as fibroblast proliferation and subsequently decrease giant papilla formation

    Full Text Available Pier Luigi Dodi Department of Veterinary Medicine Sciences, University of Parma, Parma, Italy Abstract: Keratoconjunctivitis sicca (KCS is a frequent canine ophthalmic disease, resulting from the deficiency of one or more elements in the precorneal tear film. There are different known causes of KCS in dogs, including congenital, metabolic, infectious, drug induced, neurogenic, radiation, iatrogenic, idiopathic, and immune mediated, though the last one is the most prevalent form in dogs. Initially, clinical signs of KCS include blepharospasm caused by ocular pain, mucoid to mucopurulent ocular discharge, and conjunctival hyperemia; secondary bacterial infection may also occur, with chronicity, corneal epithelial hyperplasia, pigmentation, neovascularization, and corneal ulceration. The diagnosis of KCS is based on the presence of consistent clinical signs and measurement of decreased aqueous tear production using the Schirmer tear test. Therapy is based on administering the following topical drugs: ocular lubricant, mucolytics, antibiotics, corticosteroids, pilocarpine, and immunomodulators. These last drugs (eg, cyclosporine, pimecrolimus, and tacrolimus have immunosuppressive activity and stimulate tear production. Furthermore, the nerve growth factor is a new subject matter of the research. Although these therapies are advantageous, stimulation of natural tear production seems to provide the highest recovery in clinical signs and prevention of vision loss. The goal of the following article is to describe the recent developments about KCS in dogs emphasizing the use of new therapies. Keywords: dogs, keratoconjunctivitis sicca, treatment, NGF

    Human adenoviruses (HAdV), species D in particular (HAdV-D), are frequently associated with epidemic keratoconjunctivitis (EKC). Although the infection originates at the ocular surface epithelium, the mechanisms by which HAdV-Ds bypass the membrane-associated mucin (MAM)-rich glycocalyx of the ocular surface epithelium to trigger infection and inflammation remain unknown. Here, we report that an EKC-causing adenovirus (HAdV-D37), but not a non-EKC-causing one (HAdV-D19p), induces ectodomain release of MUC16-a MAM with barrier functions at the ocular surface-from cultured human corneal and conjunctival epithelial cells. HAdV-D37, but not HAdV-D19p, is also found to decrease the glycocalyx barrier function of corneal epithelial cells, as determined by rose bengal dye penetrance assays. Furthermore, results from quantitative PCR (qPCR) amplification of viral genomic DNA using primers specific to a conserved region of the E1B gene show that, in comparison to infection by HAdV-D19p, infection by HAdV-D37 is significantly increased in corneal epithelial cells. Collectively, these results point to a MUC16 ectodomain release-dependent mechanism utilized by the EKC-causing HAdV-D37 to initiate infection at the ocular surface. These findings are important in terms of understanding the pathogenesis of adenoviral keratoconjunctivitis. Similar MAM ectodomain release mechanisms may be prevalent across other mucosal epithelia in the body (e.g., the airway epithelium) that are prone to adenoviral infection. IMPORTANCE Human adenoviruses (HAdVs) are double-stranded DNA viruses that cause infections across all mucosal tissues in the body. At the ocular surface, HAdVs cause keratoconjunctivitis (E. Ford, K. E. Nelson, and D. Warren, Epidemiol Rev 9:244-261, 1987, and C. M. Robinson, D. Seto, M. S. Jones, D. W. Dyer, and J.

    Objective: To determine the prevalence of ACD in atopics in comparison to non-atopics in our community. Design: Cross sectional study. Place and Duration of Study: Departments of Dermatology, King Edward Medical College/Mayo Hospital, Lahore, from May 1998 to July 1999. Subjects and Methods: Two hundred and fifty patients, 34 with past or present atopic dermatitis (Group I), 88 with personal or familial atopy (Group II) and 128 non-atopic with contact dermatitis (Group III) were subjected to patch testing with European standard series. The results were interpreted according to International Contact Dermatitis Research Group guidelines. Results: Positive reactions were seen in 50%, 70.4% and 67.8% of patients in the respective groups (p>0.05). Conclusion: Our results suggest that atopics are equally affected with contact dermatitis as compared with non-atopics and recalcitrant cases of atopic dermatitis should be patch tested to find out aggravating factors.

    The serological cross reactions between Mycoplasma conjunctivae, the etiological agent of infectious keratoconjunctivitis (IKC), and the antigenetically and phylogenetically closely related Mycoplasma ovipneumoniae, which is often found in sheep, were analysed. Cross reacting antigens were identified using sera from sheep with IKC and from sheep of herds known to be free of IKC, as well as rabbit hyperimmune serum specific to the two Mycoplasma species. Cross reactions were predominantly due to the strongly antigenic proteins of 42 kDa and 83 kDa. Serospecific antigens of M. conjunctivae could be separated from cross-reacting antigens by the extraction of Tween 20-soluble membrane proteins. The Tween 20-extracted proteins of the M. conjunctivae strain HRC/581T were used for the development of an indirect ELISA test. This ELISA test was shown to be a useful serological method for the diagnosis of M. conjunctivae infections and to identify infected sheep herds.

    Full Text Available The atopic march is defined as the progression of atopic diseases, generally during childhood, such as atopic dermatitis, asthma, allergic rhinitis and food allergies. The main risk factors for developing these atopic diseases include genetics, aeroallergens, food allergens, late food introduction to the infant, and living in developing countries. The immunologic contributors to this problem include the Th2 response, epigenetics, and lack of certain factors like thymic stromal lymphopoietin (TSLP and filaggrin. As a whole, the therapeutic approach has been changing during recent years because of the discovery of new factors involved in this problem. This article explains the definition of atopic march, the immunological pathway, clinical features, epidemiology and therapeutic approaches to create a context for the broader understanding of this important condition.

    Atopic dermatitis (AD) of the adult is a common skin disease. Its prevalence has greatly increased during the past decades. AD is commonly associated with other atopic disorders. Its impact on quality of life is often underestimated. Various immunopathologic mechanisms are involved in AD: innate epidermal barrier dysfunction due to filaggrin gene mutations, innate and adaptative abnormalities of the immune system (an initial Th2 phase precedes a chronic Th1 phase), intestinal and cutaneous microbiomes dysbiosis, and environmental factors. Diagnosis of AD is clinical and there is no predictive biomarker of future severity. The main differential diagnoses are: scabies, psoriasis, cutaneous adverse reaction, cutaneous T cell lymphoma, primary immunodeficiency, and Netherton's syndrome. Therapeutic management is challenging and should integrate a therapeutic education program. Topical corticosteroids are the first line treatment, including a preliminary assessment of possible topical corticosteroids phobia. Systemic treatments are recommended in severe, chronic and resistant AD, after careful evaluation in a reference centre. Dupilumab, an IL4/IL13 inhibitor, might be the first effective targeted therapy in AD, whereas therapies that specifically target the mechanisms of pruritus represent an exciting perspective.

    Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease which usually starts during the first years of life. In the management of AD, the correct approach requires a combination of multiple treatments to identify and eliminate trigger factors, and to improve the alteration of the skin barrier. In this article we try to explain the importance of skin care in the management of AD in relation to the use of textiles: they may be useful to improve disrupted skin but they are also a possible cause of triggering or worsening the lesions. Garments are in direct contact with the skin all day long, and for this reason it is important to carefully choose suitable fabrics in atopic subjects who have disrupted skin. Owing to their hygienic properties fabrics produced from natural fibres are preferential. Wool fibres are frequently used in human clothes but are irritant in direct contact with the skin. Wool fibre has frequently been shown to be irritant to the skin of atopic patients, and for this reason wool intolerance was included as a minor criterion in the diagnostic criteria of AD by Hanifin and Rajka in 1980. Cotton is the most commonly used textile for patients with AD; it has wide acceptability as clothing material because of its natural abundance and inherent properties like good folding endurance, better conduction of heat, easy dyeability and excellent moisture absorption. Silk fabrics help to maintain the body temperature by reducing the excessive sweating and moisture loss that can worsen xerosis. However, the type of silk fabric generally used for clothes is not particularly useful in the care and dressing of children with AD since it reduces transpiration and may cause discomfort when in direct contact with the skin. A new type of silk fabric made of transpiring and slightly elastic woven silk is now commercially available (Microair Dermasilk) and may be used for the skin care of children with AD.

    Atopic dermatitis is a chronic inflammatory skin condition including severe pruritus, xerosis, visible eczematous skin lesions that mainly begin early in life. Atopic dermatitis exerts a profound impact on the quality of life of patients and their families. The estimated lifetime prevalence of atopic dermatitis has increased 2~3 fold during over the past 30 years, especially in urban areas in industrialized countries, emphasizing the importance of life-style and environment in the pathogenesis of atopic diseases. While the interplay of individual genetic predisposition and environmental factors contribute to the development of atopic dermatitis, the recent increase in the prevalence of atopic dermatitis might be attributed to increased exposure to various environmental factors rather than alterations in human genome. In recent decades, there has been an increasing exposure to chemicals from a variety of sources. In this study, the effects of various environmental chemicals we face in everyday life - air pollutants, contact allergens and skin irritants, ingredients in cosmetics and personal care products, and food additives - on the prevalence and severity of atopic dermatitis are reviewed.

    Difficult to control atopic dermatitis (AD) presents a therapeutic challenge and often requires combinations of topical and systemic treatment. Anti-inflammatory treatment of severe AD most commonly includes topical glucocorticosteroids and topical calcineurin antagonists used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, the topical calcineurin inhibitors tacrolimus and pimecrolimus are preferred in certain locations. Systemic anti-inflammatory treatment is an option for severe refractory cases. Microbial colonization and superinfection contribute to disease exacerbation and thus justify additional antimicrobial / antiseptic treatment. Systemic antihistamines (H1) may relieve pruritus but do not have sufficient effect on eczema. Adjuvant therapy includes UV irradiation preferably of UVA1 wavelength. "Eczema school" educational programs have been proven to be helpful. PMID:23663504

    Full Text Available Phototherapy has still great importance in the treatment of atopic dermatitis, though costs, compliance, and long-term risks narrow its relevance. In spite of its long history, up to now, the therapeutic regimes are mostly empirical. Narrowband UVB und UVA1 are the most frequently applied regimens in atopic dermatitis with proven efficacy. However, even for these modalities randomized prospective and controlled studies are still pending. Advances in photoimmunology and molecular biology had demonstrated that phototherapy targets inflammatory cells, alters cytokine production, and has a significant antimicrobial effect within atopic skin. This paper summarizes the current literature on the different regimes of phototherapy and also discusses therapeutic modalities like photochemotherapy and extracorporeal photopheresis. These more complex regimes should be restricted to severe cases of atopic dermatitis, which are refractory to topical treatment.

    Advances in knowledge of neurocellulars relations have provided new directions in the understanding and treatment of numerous conditions, including atopic dermatitis. It is known that emotional, physical, chemical or biological stimuli can generate more accentuated responses in atopic patients than in non-atopic individuals; however, the complex network of control covered by these influences, especially by neuropeptides and neurotrophins, and their genetic relations, still keep secrets to be revealed. Itching and airway hyperresponsiveness, the main aspects of atopy, are associated with disruption of the neurosensory network activity. Increased epidermal innervation and production of neurotrophins, neuropeptides, cytokines and proteases, in addition to their relations with the sensory receptors in an epidermis with poor lipid mantle, are the aspects currently covered for understanding atopic dermatitis.

    In this dissertation, they present a study of the untagged decay of B$0\\atop{s}$ → J/ΨΦ, the final state of which is a superposition of the CP-even and CP-odd states. Within the framework of the standard model (SM), to a good approximation, the two CP eigenstates of the (B$0\\atop{s}$, $\\bar{B}$$0\\atop{s}$) system are equivalent to mass eigenstates. The data collected by the D0 detector between June 2002 to August 2004 (an integrated luminosity of approximately 450 pb-1) has been used for the analysis presented in this thesis. From a simultaneous fit to the B$0\\atop{s}$ candidate mass, lifetime, and the angular distribution of the decay products, they obtain the CP-odd fraction in the final state at production time to be 0.16 ±} 0.10(stat) ± 0.02(syst). The average lifetime of the (B$0\\atop{s}$, $\\bar{B}$$0\\atop{s}$) system is measured to be 1.39$+0.13\\atop{-0.16}$(stat)$+0.01\\atop{-0.02}$(syst) ps, with the relative width difference between the heavy and light mass eigenstates, Δγ/$\\bar{γ}$ = (γLH)/$\\bar{γ}$ = 0.24$+0.16\\atop{-0.38}$(stat)$+0.03\\atop{-0.04}$(syst). With the additional constraint from the world average of the B$0\\atop{s}$ lifetime measurements using semileptonic decays, they find average lifetime of the (B$0\\atop{s}$, $\\bar{B}$$0\\atop{s}$) system 1.39 ± 0.06 ps with Δγ/$\\bar{γ}$ = 0.25$+0.14\\atop{-0.15}$. They have also done B0 lifetime measurement for its analogous decay mode to J/Ψ}K*. With this measurement they get B0 lifetime 1.530 ± 0.043(stat) ± 0.023(syst) ps. Using above results, they get 0.91 ± 0.09(stat) ± 0.003(syst), for the ratio of the B$0\\atop{s}$ and B0 lifetimes ($\\bar{γ}$(B$0\\atop{s}$)/γ(B0)). These measurements are consistent with the predictions of SM within the measurement uncertainty.

    Keratoconjunctivitis sicca (KCS) or dry eye disease (DED) is an immune-mediated multifactorial disease, with high level of prevalence in humans and dogs. Our aim in this study was to investigate the therapeutic effects of allogeneic adipose-derived mesenchymal stromal cells (Ad-MSCs) implanted around the lacrimal glands in 12 dogs (24 eyes) with KCS, which is refractory to current available treatments. Schirmer tear test (STT) and ocular surface integrity were assessed at 0 (before treatment), 3, 6, and 9 months after treatment. Average STT values and all clinical signs showed a statistically significant change (P < 0.001) during the follow-up with reduction in all ocular parameters scored: ocular discharge, conjunctival hyperaemia, and corneal changes, and there were no signs of regression or worsening. Implanted cells were well tolerated and were effective reducing clinical signs of KCS with a sustained effect during the study period. None of the animals showed systemic or local complications during the study. To our knowledge, this is the first time in literature that implantation of allogeneic Ad-MSCs around lacrimal glands has been found as an effective therapeutic alternative to treat dogs with KCS. These results could reinforce a good effective solution to be extrapolated to future studies in human. PMID:25802852

    Full Text Available Hormones may play a role in the pathophysiology of vernal keratoconjunctivitis (VKC. An increased incidence of thyroid autoantibodies was recently observed in VKC, although there were no data on thyroid function. Two hundred and eighty-eight patients (202 males, 86 females; range 5.5 to 16.9 years with VKC were evaluated and compared with 188 normal age- and sex-matched subjects. In all subjects, serum concentrations of free T4, TSH, thyroperoxidase, thyroglobulin, and TSHr autoantibodies were evaluated. In VKC, the family history of thyroid diseases showed no significant differences compared to the controls (9.4 versus 8.6%, whereas the family history of autoimmune diseases was significantly higher (13.2% versus 6.3%; P<0.05. Subclinical hypothyroidism was diagnosed in 6.6% (versus 1.6% of the controls; P<0.05 and overt hypothyroidism in 0.7% (versus 0.0% of the controls; P=NS. Finally, 5.2% of patients were positive for thyroid autoantibodies, which were significantly higher with respect to the controls (0.5%, P<0.05. In the patients positive for thyroid autoantibodies, 80% showed a sonography pattern that suggested autoimmune thyroiditis. Thyroid function and autoimmunity abnormalities are frequently present in children with VKC. Children with VKC should be screened for thyroid function and evaluated for thyroid autoimmunity.

    In this study, the effect of cyclosporin A (CsA) eye drop on keratoconjunctivitis Sicca (KCS) and its mechanism were studied. The KCS models were established by injecting Pertussis vaccine, complete freunds adjuvant (CFA) and antigen of conjunctiva from isotype mice. Then the KCS models were treated with cyclosporin A eye drop. Changes in breaking-up time (BUT), lacrimal secretion in 30 min and diversion in 24 h were measured. The percentage of beaker cells, the lymphocytic infiltration in conjunctiva were observed. The expression levels of Aquaporin-3(AQP3) in conjunctiva epithelial cells, beaker cells and accessory lacrimal gland were immunohistochemically detected. The results showed that there were significant differences in BUT, the percentage of beaker cells, lacrimal secretion in 30 min, the lymphocytic infiltration and the expression of AQP3 between the experimental group and an control group. It was concludedthat CsA eye drop exerts marked therapeutic effect on KCS by inhibiting T lymph cells, increasing the goblet cells and AQP3 expression in conjunctiva.

    Full Text Available Purpose: To investigate the correlations between conjunctival inflammatory status and meibomian gland (MG morphology in vernal keratoconjunctivitis (VKC patients by using in vivo confocal microscopy (CM. Materials and Methods: Nineteen VKC patients (7 limbal, 7 tarsal, and 5 mixed forms and 16 normal volunteers (controls were enrolled. All subjects underwent CM scanning to obtain the images of upper palpebral conjunctiva and MGs. Inflammatory cell (IC density in palpebral conjunctival epithelial and stromal layers, Langerhans cell (LC density at lid margins and the stroma adjacent to the MG, and MG acinar unit density (MGAUD were recorded. The longest and shortest diameters of MG acinar were measured. The Kruskal-Wallis test was used to compare the parameter differences whereas the Spearman′s rank correlation analysis was applied to determine their correlations. Results: Among all groups, no significant statistical differences were found in epithelial and stromal IC densities, mean values of MG acinar unit densities, or longest and shortest diameters. Both LC parameters in the tarsal-mixed groups were significantly higher than those in the limbal and control groups. All LC densities of VKC patients showed a positive correlation with MGAUD and shortest diameter. Conclusions: In VKC patients, the conjunctival inflammatory status could be associated with the MG status. In vivo CM is a noninvasive, efficient tool in the assessment of MG status and ocular surface.

    Atopic dermatitis (AD) is a chronic, pruritic, inflammatory skin disease which predominantly affects children usually clearing up during or after childhood. However, AD may persist with a chronic recurrent course until adulthood, being recalcitrant to any treatment strategy. Moreover, in some patients AD is not present during childhood but starts later in life (i.e. after 16 years of age) being defined late-onset AD. Even if AD incidence is increasing worldwide with cases in which clinical manifestations first appeared or persisted during adolescence and adulthood raising, especially in industrialized countries, studies on adult AD are still scant. Since this subgroup of AD patients often has a nonflexural rash distribution, and atypical morphologic variants and validated diagnostic criteria are lacking, there is no clear consensus on the diagnostic work-up that should be performed when evaluating adult patients with AD. In this review the many aspects of work-up in adult patients with AD, such as diagnostic criteria, epidemiology, quality of life and pathogenesis are discussed. PMID:25658440

    Subepithelial infiltrates secondary to adenoviral keratoconjunctivitis may persist for years and cause blurred vision, halos, glare, and photophobia. These infiltrates arise from immune reaction against the virus, and few studies have reported topical cyclosporine A to be effective in the treatment of subepithelial infiltrates. Herein, we describe a patient with adenoviral keratoconjunctivitis-related subepithelial infiltrates who did not respond to treatment with a new topical cyclosporine A emulsion prepared with castor oil (Depores 0.05%; Deva İlaç, Kocaeli, Turkey), while the FDA-approved nanoemulsion formulation provided improvement in symptoms and reduced the inflammatory reaction (Restasis 0.05%; Allergan, Irvine, Calif., USA).

  11. Probiotics and Atopic Dermatitis in Children

    Full Text Available There is increasing interest in the potential beneficial role of probiotic supplementation in the prevention and treatment of atopic diseases in children. Probiotics are defined as ingested live microorganisms that, when administered in an adequate amount, confer a health benefit to the host. They are mainly represented by Lactobacilli and Bifidobacteria. Several epidemiological data demonstrate that intestinal microflora of atopic children is different from the one of healthy children. Many literature data show that probiotics may modulate the intestinal microflora composition and may have immunomodulatory effect. Based on this hypothesis, probiotics are supposed to confer benefits to allergic diseases. Administration of probiotics when a natural population of indigenous intestinal bacteria is still developing could theoretically influence immune development by favoring the balance between Th1 and Th2 inflammatory responses. For this reason, some studies have evaluated the potential impact of probiotics supplementation in the prevention of atopic dermatitis, with contrasting results. Clinical improvement in immunoglobulin (IgE-sensitized (atopic eczema following probiotic supplementation has been reported in some published studies and the therapeutic effects of probiotics on atopic dermatitis seemed to be encouraging. However, as far as the usefulness of probiotics as a prevention strategy is concerned, results are still inconclusive. In fact, the clinical benefits of probiotic therapy depend upon numerous factors, such as the type of bacteria, dosing regimen, delivery method and other underlying host factors, such as age and diet. More studies are still needed to definitively prove the role of probiotics in the treatment of allergic eczema.

    Due to the narrow associations between the skin, immune system, and nervous system, nerve endings are very important in the pathophysiology of inflammatory dermatoses and especially in atopic dermatitis. Many neurotransmitters and nerve growth factors that are released in blood or skin are involved in neurogenic inflammation, which dramatically enhance the inflammation induced by immune cells. During times of stress, their release is highly enhanced. In atopic dermatitis lesions, there are many specific changes in skin neurobiology and neurophysiology. These interesting data suggest that novel therapeutic possibilities can be imagined.

    Infectious bovine keratoconjunctivitis (IBK) is one of the most economically important diseases in preweaned calves. This study examined the health records of 45,497 calves over a 20-yr period to determine environmental and genetic factors influencing the incidence of IBK. Three data sets were analyzed with an animal model. The first data set (n = 41,986) evaluated environmental factors and genetic differences among nine purebred (Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Pinzgauer, Red Poll, and Simmental) and three composite breeds (MARC I, MARC II, and MARC III). Weaning weights of calves diagnosed with IBK were 8.9 kg lighter (P < 0.05) than weights of healthy calves. Incidence of IBK was related to age of the calf and the seasonal life cycle of the face fly (Musca autumnalis). Incidence of IBK increased in the spring (June), peaked during the summer months (July to September), and then decreased in the fall. Herefords were the most susceptible breed (P < 0.05) compared with all other purebreds and composites. Estimates of direct heritability for the incidence of IBK were generally low and ranged from 0.00 to 0.28 by breed. The maternal permanent environmental and genetic effects of the dam on the incidence of IBK were not significant for most breeds. The second data set (n = 9,606) was used to estimate heterosis for the incidence of IBK from a Hereford and Angus diallel design. The heterosis effect for the incidence of IBK in reciprocal Hereford/Angus crossbred calves was slightly negative (P = 0.12) but not large. The higher incidence of IBK in Angus x Hereford calves compared with Hereford x Angus calves (13.3 vs. 8.9%) suggests a maternal effect related to the incidence of IBK. Incidence of IBK in crossbred calves sired by tropically adapted breeds (Brahma, Boran, Tuli) compared with purebred and crossbred Bos taurus types was investigated in the third data set (n = 2,622). Crossbred calves sired by tropically adapted breeds had a lower

    Full Text Available Qualitative and quantitative abnormalities in primary components of the tear can alter the dynamics of the lacrimal film, compromising its function. Lipids, an aqueous fraction and mucoproteins constitute the lacrimal film. Keratoconjunctivitis sicca (KCS is a disease commonly diagnosed in dogs. It is characterized by the deficiency of the aqueous fraction in the lacrimal film that results in dryness, inflammation of the conjunctive and cornea with progressive corneal illness and reduction of vision and pain. Due to the significant contribution of the third eyelid lacrimal gland to the production of the aqueous fraction of the lacrimal film, the removal of this gland when prolapsed is an important cause of iatrogenic keratoconjuctivitis sicca. This paper describes a clinical case of iatrogenic keratoconjuctivitis sicca in a 10 month-old Boston Terrier which was caused by the removal of the third eyelid lacrimal gland due to its prolapse.Anormalidades quali-quantitativas em componentes primários da lágrima podem alterar a dinâmica do filme lacrimal, comprometendo sua função.

Devido à contribuição significativa da glândula da terceira pálpebra na produção da porção aquosa do filme lacrimal, a remoção desta glândula, quando prolapsada, constitui-se em importante causa de CCS iatrogênica. Este trabalho relata um caso clínico de ceratoconjuntivite seca iatrogênica, em um cão da raça Boston Terrier de 10 meses de idade, causada pela remoção cirúrgica da glândula lacrimal da terceira pálpebra, quando esta encontrava-se prolapsada.

    We present the first observation of the decay $\\bar{B}$$0\\atop{s}$→ D$±\\atop{s}$ K∓ and measure the relative branching fraction of $\\bar{B}$$0\\atop{s}$ → D$±\\atop{s}$ K∓ to $\\bar{B}$$0\\atop{s}$ → D$+\\atop{s}$ π-. The measurement of the relative branching fraction is performed by applying a fit in invariant mass and specific ionization to 1.2 fb-1 of Ds(φπ)X data collected with the CDF II detector in pp collisions at √ s = 1.96 TeV at the Fermilab Tevatron collider. We measure B $\\bar{B}$$0\\atop{s}$ → D$±\\atop{s}$ K∓ /B $\\bar{B}$$0\\atop{s}$ → D$+\\atop{s}$ π- = 0.107±0.019(stat)±0.008(sys). The statistical significance of the $\\bar{B}$$0\\atop{s}$ → D$±\\atop{s}$ K signal is 7.9σ. To cross-check our analysis method, we also measure B $\\bar{B0}$→ D+K- /B $\\bar{B0}$ → D+π- and B $\\bar{B0}$ → D+*K- /B $\\bar{B0}$ → D*+π- and verify that our results are in agreement with the world average.

  18. Nitrosative events in atopic asthma pathogenesis

    Full Text Available The correlation between high exhaled nitric oxide levels and eosinophilic-mediated airway inflammation in patients with atopic asthma has been well documented. This generates prerequisites that a regulatory feedback mechanism exists between them. Therefore, the paper briefly describes evidence implementing biosynthesis, enzyme structural features, expression regulation of its isoforms and effects of nitric oxide, which have helped elucidate molecular mechanisms by which nitric oxide selectively promotes asthma exacerbation. In previous study we have demonstrated that airway infiltrate of immune cells contributes to NO synthesis in the respiratory tract during allergic inflammation under guinea pig model of acute asthma with multiple challenges. On the basis of these findings the authors posits that nitric oxide represents an additional signal of the induction of Th2 subset response and be considerably involved in the complex network of immune regulation distinctive for atopic asthma phenotype.

  19. Skin barrier in atopic dermatitis: beyond filaggrin*

    Atopic dermatitis is a chronic inflammatory skin disease with a complex pathogenesis, where changes in skin barrier and imbalance of the immune system are relevant factors. The skin forms a mechanic and immune barrier, regulating water loss from the internal to the external environment, and protecting the individual from external aggressions, such as microorganisms, ultraviolet radiation and physical trauma. Main components of the skin barrier are located in the outer layers of the epidermis (such as filaggrin), the proteins that form the tight junction (TJ) and components of the innate immune system. Recent data involving skin barrier reveal new information regarding its structure and its role in the mechanic-immunological defense; atopic dermatitis (AD) is an example of a disease related to dysfunctions associated with this complex.

    Full Text Available Atopic dermatitis is a common disease which varies widely in clinical presentation at different ages and places. Although authors working in western countries on white races have suggested many criteria, there is no uniform set which can be used in large population studies in this part of the world. Hence keeping in mind differences in environment and ethnicity of population, the present study was carried out. Seventy- three patients of atopic dermatitis and 71 age matched controls were studied. All the subjects were examined using a set of 34 potentially useful clinical features selected from different studies, including features for evaluation of photosensitivity. Multiple regression technique was used for analysing the data. It was found that 6 clinical features were diagnostic, 1. presence of itch, 2. history of flexural involvement, 3. history of dry skin, 4. family history of atopy, 5. personal history of diagnosed asthma and 6, visible flexural dermatitis. Photosensitivity was not a significant feature.

    Background: Infectious bovine keratoconjunctivitis (IBK) or 'pinkeye' is an economically important ocular disease that significantly impacts animal performance. Genetic parameters for IBK infection and its genetic and phenotypic correlations with cattle tick counts, number of helminth (unspecified...... species) eggs per gram of faeces and growth traits in Australian tropically adapted Bos taurus cattle were estimated. Methods: Animals were clinically examined for the presence of IBK infection before and after weaning when the calves were 3 to 6 months and 15 to 18 months old, respectively and were also...... counts. Conclusions: Our results suggest that genetic selection against IBK incidence in tropical cattle is feasible and that calves genetically prone to acquire IBK infection could also be genetically prone to have a slower growth. The positive genetic correlations among weight traits and between tick...

    Abstract Chronic cough has been reported to be the fifth most common complaint seen by primary care physicians in the world, the third in Italy. Chronic cough in non-smoking, non-treated with ACE-inhibitor adults with normal chest radiogram could be a symptom of asthma and can be sub-classified into: cough-variant asthma, atopic cough, and eosinophilic bronchitis. This review discusses the differential diagnosis of these three disorders.

    The inactivation of virus-contaminated nonporous inanimate surfaces was investigated using adenovirus type 8, a common cause of epidemic keratoconjunctivitis. A 10-μl inoculum of adenovirus was placed onto each stainless steel disk (1-cm diameter), and the inoculum was allowed to air dry for 40 min. Twenty-one different germicides (including disinfectants and antiseptics) were selected for this study based on their current uses in health care. After a 1- or 5-minute exposure to 50 μl of the germicide, the virus-germicide test mixture was neutralized and assayed for infectivity. Using an efficacy criterion of a 3-log10 reduction in the titer of virus infectivity and regardless of the virus suspending medium (i.e., hard water, sterile water, and hard water with 5% fetal calf serum), only five disinfectants proved to be effective against the test virus at 1 min: 0.55% ortho-phthalaldehyde, 2.4% glutaraldehyde, 2.65% glutaraldehyde, ∼6,000 ppm chlorine, and ∼1,900 ppm chlorine. Four other disinfectants showed effectiveness under four of the five testing conditions: 70% ethanol, 65% ethanol with 0.63% quaternary ammonium compound, 79.6% ethanol with 0.1% quaternary ammonium compound, and 0.2% peracetic acid. Of the germicides suitable for use as an antiseptic, 70% ethanol achieved a 3-log10 reduction under four of the five test conditions. These results emphasize the need for proper selection of germicides for use in disinfecting noncritical surfaces and semicritical medical devices, such as applanation tonometers, in order to prevent outbreaks of epidemic keratoconjunctivitis.

    Atopic dermatitis is a chronic, inflammatory skin condition that affects 10% to 20% of children and 1% to 3% of adults in the US. Symptoms often result in sleeplessness, psychological stress, poor self-esteem, anxiety, and poor school or work performance. The cost of atopic dermatitis is estimated to be US$0.9 to 3.8 billion every year. Topical steroids are first-line treatment for atopic dermatitis, and recent advances in vehicle technologies have resulted in improved patient tolerability and compliance. Topical calcineurin inhibitors are also safe and effective topical treatments for atopic dermatitis, and provide an additional therapeutic option for patients with this disease. Systemic immunomodulators are used in the treatment of severe refractory disease. Cyclosporine, methotrexate, azathioprine, mycophenolate mofetil, and interferon gamma have been used in the management of severe atopic dermatitis.

    AIM To verify the prevalence of thyroid autoimmunity (TA) and the possible association between atopy and TA in children affected by skin disease. METHODS Three hundred and twenty-four children consecutively referred due to skin disease symptoms to our Pediatric Department were enrolled. One hundred and eighty-seven were diagnosed with atopic dermatitis (AD), 95 with acute urticaria, 40 with chronic urticaria (CU), and 2 with alopecia areata (AA). According to the work-up for atopy, the children were divided into two groups: Atopics and non-atopics. TA was diagnosed by serum thyroid peroxidase autoantibodies and/or thyroglobulin autoantibodies levels more than twice normal values over a period of two months by immunoassay. RESULTS In all children with skin disease, a significant prevalence of TA in atopics compared with non-atopics (13.67% vs 2.67%, P = 0.0016) and a significant association between TA and atopy (OR = 5.76, 95%CI: 1.71-19.35) were observed. These findings were confirmed as significant in children with AD: TA in atopics was 11.5%, while TA in non-atopics was 2.7% (P = 0.03, OR = 4.68, 95%CI: 1.02-21.38). In addition, atopics with CU showed a significantly higher prevalence of TA (26.9%), but none of the non-atopics showed CU (P = 0.0326). On the other hand, atopics with AA showed a 100% (2 out of 2) prevalence of TA, compared with none of the non-atopics. CONCLUSION In children with skin disease, atopy seems to be associated with an increased risk of TA. PMID:27610344

To evaluate a possible role of sex hormones in VKC, serum levels of sex hormones in children and adolescents with VKC were assessed. Methods. 12 prepubertal and 7 early pubertal boys with active VKC and 6 male patients with VKC in remission phase at late pubertal age and 48 healthy age and sex-matched subjects were included. Serum concentration of estrone, 17 beta-estradiol, dehydroepiandrosterone-sulfate, total testosterone and free testosterone, dihydrotestosterone (DHT, cortisol, delta-4-androstenedione, follicle-stimulating hormone, luteinizing hormone, and sex-hormones binding globuline (SHBG were evaluated. Results. Serum levels of Estrone were significantly increased in all groups of patients with VKC when compared to healthy controls (P<0.001. Prepubertal and early pubertal VKC showed a significant decrease in DHT (P=0.007 and P=0.028, resp. and SHBG (P=0.01 and P=0.002, resp. when compared to controls and serum levels of SHBG were increased in late pubertal VKC in remission phase (P=0.007. Conclusions and Relevance. VKC patients have different circulating sex hormone levels in different phases of the disease and when compared to nonallergic subjects. These findings suggest a role played by sex hormones in the pathogenesis and/or activity of VKC.

    To evaluate the efficacy and safety of resection and cryotherapy combined with amniotic membrane transplantation (AMT) for the treatment of vernal keratoconjunctivitis (VKC) with giant papillae (GP). Eight patients (16 eyes involved) with VKC, characterized by GP on the upper tarsal conjunctiva, underwent resection and cryotherapy in combination with AMT. The follow-up lasted for 3-22 months. The results showed that corneal shield ulcers and superficial punctuate keratitis healed during the first week after surgery and did not recur. Fourteen eyes (87.5 %) were symptom-free 1 month after surgery, and no GP, ectropion, trichiasis and other complications were noted, but the blood vessels of upper tarsal conjunctiva could not be clearly seen and a little conjunctival scar was observed. Recurrence of GP was observed in 2 eyes (12.5 %), with the area being less and irritation milder as compared with those before the operation. Among the two eyes, one eye was treated by cyclosporine eyedrops with improvement, but the other eye showed no improvement after the treatment, and underwent a second surgery with a cotton patch soaked in fluorouracil applied onto the supratarsal area after resection and cryotherapy. Four months after the treatment the patient presented no symptoms and GP did not recur. It is concluded that the resection and cryotherapy combined with AMT is an effective and safe treatment for VKC with GP.

    Onset of atopic dermatitis and occurrence of related skin lesions are influenced by various environmental factors in humans, and companion animals. Several studies have demonstrated an association between passive smoking and the development of atopic dermatitis in children. This association has never been investigated in the dog to our knowledge. We enrolled 161 dogs seen at dermatology and vaccination consultations over a six-month period for this study. Dog owners were asked to complete a questionnaire, to evaluate the exposure of the dog to tobacco smoke. The atopic or non-atopic status of the dog was assessed on the basis of Favrot's criteria (history, clinical examination and cutaneous cytology for Malassezia). Analysis of the data for the 161 dogs enrolled revealed a significant association between high levels of passive exposure to tobacco smoke (cigarette consumption divided by the area of the home) and the presence of atopic dermatitis in the dogs (OR, 4.38; 95% CI, 1.10-17.44; p=0.03; NNH (number needed to harm) 3, 95% CI 2-52). The prevalence of atopic dermatitis showed a slight, but non-significant association with breed predisposition. Dogs with high levels of exposure to tobacco smoke may have a higher risk of atopic dermatitis than non-exposed dogs. PMID:24491262

    To develop a prophylactic recombinant HPV58L1-attenuated Shigella live vector vaccine and evaluate its protective efficacy and immunogenicity in the guinea pig keratoconjunctivitis model, the HPV58L1 gene was cloned into vector pUCmt, and then subcloned into the suicide vector pCVD442. The recombinant plasmid pCVD442-HPV58L1 was introduced into attenuated Shigella (sf301:△virG) with the helper plasmid PRK2013 by filter mating. The positive colonies were harvested and confirmed by polymerase chain reaction. The expression of the HPV58L1 protein with a molecu-lar weight of 60 kDa was confirmed by western blot. The ability of the interested protein to self-assemble into virus-like particles was identified by transmission electron microscope, and murine erythrocyte hemagglu-tination assay. The guinea pig keratoconjunctivitis model was used to evaluate the protective efficacy and immunogenicity of the vaccine. Animal experiments showed that there was no keratoconjunctivitis occurred in the immunized group (HPV58-attenuated Shigella), and the serum levels of anti-HPV58L1-IgG and -IgA were obviously increased (P0.05). Enzyme-linked immunosorbent spot assay showed that HPV58L1-specific IgA-antibody-secreting cells (ASC) and IgG-ASC of spleen and lymph nodes were also obviously increased (P<0.01). In this study, a recombi-nant HPV58L1-attenuated Shigella live vector vaccine was successfully constructed, and it could induce strong humoral immune responses in the immunized animals, and induce protective antibody production.

    Atopic eczema, also known as atopic dermatitis, is a frequent, highly pruritic, chronic skin disease, which is typically running in flares. The traditional treatment mainly consists of the reactive application of topical anti-inflammatory agents such as topical corticosteroids and topical calcineurin inhibitors. The short term benefit of this approach is well known, but long term remission between flares is difficult to achieve. Therefore, innovative long-term treatment strategies targeting f...

    Moraxella bovoculi is a recently described bacterium that is associated with infectious bovine keratoconjunctivitis (IBK) or "pinkeye" in cattle. In this study, closed circularized genomes were generated for seven M. bovoculi isolates: three that originated from the eyes of clinical IBK bovine cases and four from the deep nasopharynx of asymptomatic cattle. Isolates that originated from the eyes of IBK cases profoundly differed from those that originated from the nasopharynx of asymptomatic cattle in genome structure, gene content and polymorphism diversity and consequently placed into two distinct phylogenetic groups. These results suggest that there are genetically distinct strains of M. bovoculi that may not associate with IBK.

    Although gut microbiota has been studied relatively extensively in the context of allergic diseases, there have been several contradictions between these studies. By applying high-throughput sequencing, we aimed to analyze the differences in gut microbiota between atopic and healthy children at 5 and 12 years of age. 51 stool samples were collected from 14 atopic and 15 healthy children and analyzed with 454 pyrosequencing of the 16S rRNA gene. At the ages of 5 and 12 years, Bacteroides, Prevotella, and Dialister dominated gut microbiota in both atopic and healthy groups of children. Children in the atopic group had lower abundance and prevalence of Akkermansia in gut microbiota than their healthy counterparts. Thus, the composition of gut microbiota does not seem to be significantly different between atopic and healthy children, but lower abundance and prevalence of Akkermansia indicate that this bacterium may accompany or play a role in IgE-mediated atopic diseases.

    Significant numbers of humans with atopic dermatitis develop Malassezia-specific IgE. Immediate skin-test reactivity to Malassezia has been demonstrated in atopic dogs. The aim of this study was to compare the serum IgG and IgE response to Malassezia in atopic dogs with and without clinical evidence of Malassezia dermatitis and/or otitis, nonatopic dogs with clinical evidence of Malassezia dermatitis and/or otitis and healthy dogs. Cytology was used to diagnose clinically significant Malassezia dermatitis and otitis. Contact plate cultures confirmed the validity of this technique. Reproducible enzyme-linked immunosorbent assays for Malassezia-specific IgG and IgE in canine serum were established. Atopic dogs had significantly higher serum IgG and IgE levels than either healthy dogs or nonatopic dogs with clinical evidence of Malassezia dermatitis and/or otitis. There was no significant difference in IgG and IgE levels between atopic dogs with and without clinical evidence of Malassezia dermatitis and/or otitis. The implications of these findings in the pathogenesis and management of canine atopic dermatitis are discussed. PMID:11844222

    Atopic dermatitis (AD), or eczema, can be a very challenging disease to manage. The etiology of the disease is not completely understood, and its incidence has risen in the past 10 years to more than 10% of the population. AD is characterized primarily by intense itching and the development of papules, scaly lesions, fissures, and crusting. The onset occurs primarily in childhood, and much of the disease management is conducted by the family. Patients and their families often experience multiple recurrences and exacerbations, repeated attempts at cures and treatments, lowered self-esteem of the child, impaired growth and development of the child, loss of sleep, discipline problems, and multiple clinic and emergency department visits for exacerbations. Management primarily consists of prevention (i.e., good daily skin care and management of environmental trigger factors such as infection, irritants, emotional stress, and allergens). These children and their families need education and the support of health care professionals. This article outlines specific techniques to help parents and children manage AD at home and minimize exacerbations. PMID:9579351

    Canine atopic dermatitis (CAD) is a chronic relapsing inflammatory skin disease occurring in 10% of the canine population. Although most studies have focused on the pathophysiological mechanism involved in CAD, the detrimental impact of CAD on quality of life has received only little attention. Hair cortisol analysis is becoming a valuable tool in monitoring chronic stress. To further validate this approach in CAD, we compared the hair cortisol concentration of atopic dogs with that of healthy conditioned dogs. The extent and severity of cutaneous lesions of atopic dermatitis were assessed according to modified CADESI-03 scores. In addition, skin barrier function was evaluated by measuring transepidermal water loss (TEWL) and stratum corneum conductance. The correlation between CAD severity and hair cortisol concentration was evaluated. The level of hair cortisol evaluated by ELISA assay showed that the atopic dermatitis group had significantly increased cortisol levels compared to that of the healthy control group. A significant positive correlation was identified between hair cortisol level and the CADESI score in CAD patients. The TEWL value of the cubital flexor of the forelimb in the atopic group was significantly higher compared to the healthy controls. These findings imply that the hair cortisol analysis can be an effective and objective biomarker in assessment of long-term stress of CAD patients.

    Atopic dermatitis (AD) is a common disease in childhood that is a serious burden on patients and their families. Most AD is mild and can be managed with the use of emollients and standard therapy consisting of topical corticosteroids or topical calcineurin inhibitors. However, in a subgroup of patients with moderate to severe AD, the disease is recalcitrant to topical therapy and systemic treatments become necessary. Short courses of systemic corticosteroids are often used in clinical practice, but their use is controversial. International guidelines suggest that in the case of acute flare-ups, patients might benefit from a short course of systemic corticosteroids, but long-term use and use in children should be avoided. Ciclosporin is an immunosuppressant agent that acts directly on cells of the immune system, with an inhibitory effect on T cells. When AD cannot be controlled by standard topical therapies, ciclosporin significantly decreases symptom scores, disease extent, pruritus and sleep deprivation, and improves quality of life. The most frequent adverse effects associated with the use of ciclosporin are hypertension and renal dysfunction, but they are usually reversible after drug discontinuation. Ciclosporin has been found to be safely used, effective and well tolerated in children with severe AD. However, studies to assess the long-term effectiveness and safety of ciclosporin in AD are lacking. In patients for whom ciclosporin is not suitable, or when there is a lack of response, alternative drugs should be considered, such as azathioprine or interferon-gamma. Intravenous immunoglobulins and the monoclonal antibody infliximab only have a place in the systemic therapy of AD when other drugs have failed. Mycophenolate mofetil has recently been introduced in the treatment of recalcitrant AD. Efalizumab and omalizumab are monoclonal antibodies with a possible future role in the treatment of AD, but further studies are needed. PMID:19275273

    Full Text Available Dendritic cells are important residents of the lung environment. They have been associated with asthma and other inflammatory diseases of the airways. In addition to their antigen-presenting functions, dendritic cells have the ability to modulate the lung environment to promote atopic disease. While it has long been known that respiratory viral infections associate with the development and exacerbation of atopic diseases, the exact mechanisms have been unclear. Recent studies have begun to show the critical importance of the dendritic cell in this process. This paper focuses on these data demonstrating how different populations of dendritic cells are capable of bridging the adaptive and innate immune systems, ultimately leading to the translation of viral illness into atopic disease.

    In this thesis, we report the study on one such particle called the B$0\\atop{s}$ meson made up of a bottom and a strange quark. B$0\\atop{s}$ mesons are currently produced in a great numbers only at the Tevatron and we report a study done to measure the mixing parameter Δms between the B$0\\atop{s}$ meson and its anti-particle $\\bar{B}$$0\\atop{s}$. Mixing is the ability of a very few neutral mesons to change from their particle to their antiparticle and vice versa. Until recently there existed only a lower limit on this measurement, here we report an upper bound and a most probable value for the mixing parameter. In the following chapter, we discuss the theoretical motivation behind this study. The measurement technique and the different factors that effect the measurement are also given. In Chapter 3, we provide an overview of the experimental setup needed to perform the study. In Chapter 4, we present a new initial state flavor tagging algorithm using electrons and measurement of the B$0\\atop{d}$ mixing parameter Δmd with the new technique. Details of the combined initial state tagging used in the B$0\\atop{s}$ mixing study are also given. A detailed description of the B$0\\atop{s}$ mixing analysis and the results are covered in Chapter 5. And finally the results from all the three channels and a bound on the mixing parameter are presented in Chapter 6.

    Etiologic factors and incidence of bronchial hyperreactivity as a 'stigma' of bronchial asthma were studied in 237 patients suffering from perennial atopic rhinitis. All pateints underwent detailed laryngologic and allergologic examiniation and pulmonary function tests at rest, after exercise, and after histamine inhalation. Most often the patients were sensitized tungal allergens. Bronchial hyperreactivity, typical of bronchial asthma, was observed in 48.52% of patients. Results were analysed statistically. It was concluded that early institution of causal therapy can cure the symptoms of rhinitis and prevent evolution of the disease into atopic bronchial asthma in patients already suffering from bronchial hyperreactivity.

    Two children are presented with autosomal recessive hyper IgE syndrome caused by a mutation in the dedicator of cytokinesis 8 gene (DOCK8). The manifestations are typically severe atopic dermatitis, food allergies, elevated serum IgE concentration, viral skin infections and risk of malignancies. DOCK8 deficiency was first reported in 2009, following the death of the oldest sibling. The youngest sibling was cured after allogenic stem cell transplantation. This case report illustrates the need of awareness of primary immunodeficiency in children with atypical manifestation of atopic dermatitis in combination with recurrent infections. PMID:26692033

    Full Text Available The majority of the studies in the field of childhood asthma lie within the scope of allergy/atopic asthma; however, airway hyperresponsiveness is considered a marker of asthma, independent of the atopic status and should be regarded as a parallel pathological process that can lead to subsequent symptoms and clinical evidence of asthma in children, without the evidence of atopy. The aim of this study is to estimate the possible differences in clinical and lung functions, and the immunological status of children with atopic and nonatopic asthma phenotypes. In a prospective study design, 54 children (age 3-18 years in Germany were monitored via active surveillance, by twice-a-week phone calls. All the children were divided into two groups, based on their atopic status, clinical date and lung function tests. The first 27 patients had atopic asthma (AA, whereas the second set of 27 patients had nonatopic asthma (NA. All patients underwent IgE and RAST tests for the most common inhalant allergens, and a quantitative measurement of Eosinophil Cationic Protein (ECP by CAP-radioallergosorbent test-fluorescence enzyme immunoassay (UniCAP, Pharmacia Diagnostics, Germany. Further, the IgA, IgM, IgG subclasses, IL-6 and CRP levels in the serum were tested. The resultant data showed significant differences in the prevailing IgE level 317.5±58 g/l in AA versus 83±21 in NA. However, there was no significant distinction either in the ECP serum level in children with atopic and nonatopic asthma or in the IL-6 serum level. An unexpected result was the significant drop in the level of serum CRP in group NA – 0.68±0.37 g/l; while in group AA this result was 1.5±0.38 g/l. No significant differences were noted between the mean values of the IgM and IgG levels in patients of all groups; however, the IgG levels increased only in the children with nonatopic asthma.

    Atopic dermatitis (AD) is an intriguing clinical entity. Its clinical connotations are varied, the updates of which are required to be done periodically. An attempt to bring its various facets have been made highlighting its clinical features keeping in view the major and the minor criteria to facilitate the diagnosis, differential diagnosis, complications, and associated dermatoses. The benefit of the current dissertation may percolate to the trainees in dermatology, in addition to revelations that atopic undertones in genetic susceptibility and metabolic disorder may provide substantive insight for the future in the understanding of thus far enigmatic etiopathogenesis of AD.

    Full Text Available Context: Atopic dermatitis is a chronic inflammatory skin disease resulting from interactions between environmental and genetic factors. Recent studies link atopic dermatitis with asthma and with eosinophilic esophagitis. Case Report: Based on this association, we investigated by indirect immunofluorescence the immunoreactivity patterns on monkey esophagus substrate utilizing the serum of a patient with severe atopic dermatitis. We also examined the patient′s skin biopsy by H&E histology and immunohistochemistry. We detected strong deposits of albumin, IgE, IgG, IgD, IgA, Complement/C1q and mast cell tryptase in multiples structures of the skin, as well as a broad pattern of intraepithelial staining on monkey esophagus. Strong staining positivity was also detected within the inflammatory infiltrate around the upper dermal vessels, as well as additional positive staining for the human leukocyte antigen system antigens DR DP and DQ. Conclusion: Our findings demonstrate that there could be an indication for testing patients with severe atopic dermatitis for autoreactivity to filaggrin (anti-keratin antibodies utilizing monkey esophagus. Larger studies are needed to clarify any immunologic interaction between the reactivity to albumin and food allergens that may sensitize patients via the esophageal mucosa.

    Colloidal oatmeal has been used for decades to soothe and ameliorate atopic dermatitis and other pruritic and/or xerotic dermatoses. In-vitro and/or in-vivo studies have confirmed the anti-inflammatory, barrier repair, and moisturizing properties of this compound. A broad set of studies has been conducted in recent years to assess the effects of colloidal oatmeal as adjunct treatment in the management of atopic dermatitis (AD). This paper will review these studies. In these investigations, patients in all age groups (3 months to 60 years) with mild to moderate atopic dermatitis were included and allowed to continue their prescribed topical medications. These studies found that the daily use of moisturizers and/or cleansers containing colloidal oatmeal significantly improved many clinical outcomes of atopic dermatitis from baseline: investigator's assessment (IGA), eczema area and severity index (EASI), itch, dryness, and quality of life indices. Safety results showed that the formulations were well tolerated in babies, children, and adults with AD. PMID:22777219

    This study aims to describe the types of intrafamilial violence perpetrated against children according to living conditions, family factors, and child characteristics, and to identify the association between types of intrafamilial violence and asthma symptoms in atopic and non-atopic children. A cross-sectional study was carried out with 1,370 caregivers as part of the Social Changes, Asthma and Allergy in Latin America (SCAALA) study, conducted in 2006 in Brazil. The study population was selected by random sampling. The main outcome measures were atopic and non-atopic asthma. We investigate the association between intrafamilial violence and asthma symptoms in atopic and non-atopic children. A backward multivariate logistic polytomous regression was performed to verify the main association. Nonviolent discipline (NVD) and maltreatment nonviolent discipline (MNVD) were positively associated with non-atopic asthma symptoms (NVD: odds ratio (OR)=1.95/95% confidence interval (CI)=1.17-3.25; MNVD: OR=1.95/95% CI=1.19-3.20). However, for the most severe intrafamilial violence, this association was not found after control of potential confounders. This study demonstrates the effect of types of intrafamilial violence on non-atopic asthma. Intrafamilial violence against children represents one more component in the determination of non-atopic asthma in Latin America. PMID:26149733

    Background Topical antimicrobial drugs are indicated for limited superficial pyodermitis treatment, although they are largely used as self-prescribed medication for a variety of inflammatory dermatoses, including atopic dermatitis. Monitoring bacterial susceptibility to these drugs is difficult, given the paucity of laboratory standardization. Objective To evaluate the prevalence of Staphylococcus aureus topical antimicrobial drug resistance in atopic dermatitis patients. Methods We conducted a cross-sectional study of children and adults diagnosed with atopic dermatitis and S. aureus colonization. We used miscellaneous literature reported breakpoints to define S. aureus resistance to mupirocin, fusidic acid, gentamicin, neomycin and bacitracin. Results A total of 91 patients were included and 100 S. aureus isolates were analyzed. All strains were methicillin-susceptible S. aureus. We found a low prevalence of mupirocin and fusidic acid resistance (1.1% and 5.9%, respectively), but high levels of neomycin and bacitracin resistance (42.6% and 100%, respectively). Fusidic acid resistance was associated with more severe atopic dermatitis, demonstrated by higher EASI scores (median 17.8 vs 5.7, p=.009). Our results also corroborate the literature on the absence of cross-resistance between the aminoglycosides neomycin and gentamicin. Conclusions Our data, in a southern Brazilian sample of AD patients, revealed a low prevalence of mupirocin and fusidic acid resistance of S. aureus atopic eczema colonizer strains. However, for neomycin and bacitracin, which are commonly used topical antimicrobial drugs in Brazil, high levels of resistance were identified. Further restrictions on the use of these antimicrobials seem necessary to keep resistance as low as possible.

    Full Text Available Abstract Background The causation of asthma is poorly understood. Risk factors for atopic and non-atopic asthma may be different. This study aimed to analyze the associations between markers of poverty, dirt and infections and wheezing in atopic and non-atopic children. Methods 1445 children were recruited from a population-based cohort in Salvador, Brazil. Wheezing was assessed using the ISAAC questionnaire and atopy defined as allergen-specific IgE ≥0.70 kU/L. Relevant social factors, environmental exposures and serological markers for childhood infections were investigated as risk factors using multivariate multinomial logistic regression. Results Common risk factors for wheezing in atopic and non-atopic children, respectively, were parental asthma and respiratory infection in early childhood. No other factor was associated with wheezing in atopic children. Factors associated with wheezing in non-atopics were low maternal educational level (OR 1.49, 95% CI 0.98-2.38, low frequency of room cleaning (OR 2.49, 95% CI 1.27-4.90, presence of rodents in the house (OR 1.48, 95% CI 1.06-2.09, and day care attendance (OR 1.52, 95% CI 1.01-2.29. Conclusions Non-atopic wheezing was associated with risk factors indicative of poverty, dirt and infections. Further research is required to more precisely define the mediating exposures and the mechanisms by which they may cause non-atopic wheeze.

    The Italian Consensus Conference on clinical management of atopic dermatitis in children reflects the best and most recent scientific evidence, with the aim to provide specialists with a useful tool for managing this common, but complex clinical condition. Thanks to the contribution of experts in the field and members of the Italian Society of Pediatric Allergology and Immunology (SIAIP) and the Italian Society of Pediatric Dermatology (SIDerP), this Consensus statement integrates the basic principles of the most recent guidelines for the management of atopic dermatitis to facilitate a practical approach to the disease. The therapeutical approach should be adapted to the clinical severity and requires a tailored strategy to ensure good compliance by children and their parents. In this Consensus, levels and models of intervention are also enriched by the Italian experience to facilitate a practical approach to the disease.

    The demonstration of IgE receptors on the surface of epidermal dendritic cells and on other antigen presenting cells is a crucial element in the understanding of the pathophysiological role of these cells in the genesis of atopic disease, and especially the atopic dermatitis (AD). The sensibilisation phase to an aeroallergen at the level of nasal or bronchial mucosa and even at the skin may be mediated by dendritic cells expressing Fc epsilon RI. Distinct forms of AD may then represent the equivalent of the ellicitation phase of the classical allergic contact dermatitis. Fc epsilon RI would lead, via specific IgE, to an efficient antigen capture, to the activation of the dendritic cells and finally to an antigen presentation. Thus, AD may represent the paradigma of an IgE-mediated type IV reaction. PMID:8786892

    Essential fatty acids are claimed to have positive effects in atopic diseases. In a double blind, placebo controlled, parallel group study 58 out of 60 children, with atopic dermatitis and the need for regular treatment with topical skin steroids, completed a 16 weeks' treatment period with either Epogam evening primrose oil or placebo capsules. Twenty two of these subjects also had asthma. The parents used diaries to record symptom scores and concomitant medication. Peak expiratory flow was measured and disease activity was monitored by the clinician every four weeks. The plasma concentrations of essential fatty acids increased significantly in the group treated with Epogam capsules. The study demonstrated significant improvements of the eczema symptoms but no significant difference was found between the placebo and the Epogam groups. No therapeutic effect was shown on asthma symptoms or fidget.

    Hypnosis is well known for its modulatory effects on immune and inflammatory processes, and it is a therapeutic option for certain diseases of such pathogenesis. The authors report treatment of an adult patient with extensive atopic dermatitis, who was only minimally responsive to conservative treatment. In a 15 session hypnotherapy the authors combined the use of direct, symptom-oriented suggestive techniques with hypnotic procedures to identify and modify comorbid psychological issues. To monitor the effect of the treatment, patient diaries (quality and quantity of sleep, intensity of pain and itch) and repeated psychometric tests were used. At the end of treatment there were improvements in all measured dimensions (itch, pain, insomnia, activity, anxiety and emotional state) both clinically and psychometrically. The authors conclude, that hypnosis can be an effective adjunctive therapy in atopic dermatitis, and in certain severe cases may constitute a salvage therapy. PMID:26929974

    Full Text Available The goal of our study was to assess the chemotactic activity for eosinophils (ECA and neutrophils (NCA and histamine releasing activity (HRA in crude supernatants of mononuclear cells in monosensitized atopic asthmatics and healthy controls. Chemotactic activity for ECA and neutrophils was measured in supernatants of cultured mononuclear cells with modified Boyden’s chamber and HRA was assessed on healthy donor basophils. With respect to ECA generation two distinct subgroups of subjects were distinguished: releasers [ECA (+] and non-releasers [ECA (–]. In atopic and non-atopic ECA (+ the mean ECA index was 3.78 ± 0.49 and 2.47 ± 0.27 respectively (P > 0.05. Supernatants from the remaining subjects (seven of 22 atopic and five of 11 non-atopic did not express ECA, but revealed significant inhibitory activity for chemokinesis of eosinophils (mean chemotactic index 0.25 ± 0.16 and 0.48 ± 0.22 for atopic and non-atopic non-releasers respectively. Stimulation with antigen of MNC from atopic and with PHA from non-atopic ECA (– restored cells ability to release ECA. Sephadex gel chromatography revealed that supernatants of MNC contained chemotactic and chemokinesis inhibitory activity in different fractions. The spontaneous productions of NCA and HRA by mononuclear cells was sim ilar in ECA releasers and non-releasers, although the HRA was higher following stimulation with PHA in the non-atopic ECA (+ subgroup. Our study demonstrated, for the first time, that MNC are capable of generating not only chemotactic activity but also chemokinesis inhibitory activity for eosinophils.

    Chronic otitis media with effusion (OME) is associated with irreversible changes in the middle ear, sometimes leading to hearing loss and abnormal language development in children. While the pathogenesis of OME is not fully understood, inflammatory and allergic factors are thought to be involved. The study aimed to investigate the role of cytokines in the local development of chronic OME, and assess differences in the cytokine profiles between atopic and non-atopic children. 84 atopic and non-atopic children with chronic OME (mean age of 6 years 7 months) were studied. Age-matched children with hypertrophy of the adenoids and Eustachian tube dysfunction served as the control group. The number of past acute otitis media (AOM) episodes, their age, and the type of effusion were recorded for all children. Pro-inflammatory cytokine concentrations (TNF-α, IL-1β, IL-6 and IL-8) were determined and the presence of pathogenic bacteria in the patients' effusions was examined. High concentrations of TNF-α, IL-1β, IL-6 and IL-8 were found in the effusions in all children with chronic OME, with the highest levels observed in the non-atopic group. The atopic group showed persistently high IL-1β levels, while in the non-atopic children, IL-1β and TNF-α levels positively correlated with the patient's age and the number of past AOM episodes. Pathogenic bacteria were more frequently isolated from effusions in non-atopic children. In both atopic and non-atopic children, pro-inflammatory cytokines are found at high concentrations. This argues in favor of instituting anti-inflammatory management for treating OME, regardless of atopy. PMID:26078091

    2013-01-01

    Atopic dermatitis (AD) is an inflammatory skin disease commonly affecting children and managed by pediatricians, primary care physicians, allergists, and dermatologists alike. For many years, the only available topical pharmacological treatment was topical corticosteroids. This changed in 2000–2001, when topical formulations of two calcineurin inhibitors (tacrolimus and pimecrolimus) were approved for short-term or chronic intermittent treatment of AD in patients ≥2 years of age, in whom othe...

  6. The role of melatonin in autoimmune and atopic diseases

    Full Text Available Melatonin is the main secretory product synthesized and secreted by the pineal gland during the night. Melatonin is a pleitropic molecule with a wide distribution within phylogenetically distant organisms and has a great functional versatility, including the regulation of circadian and seasonal rhythms and antioxidant and anti-inflammatory properties. It also possesses the capacity to modulate immune responses by regulation of the TH1/TH2 balance and cytokine production. Immune system eradicates infecting organisms without serious injury to host tissues, but sometimes these responses are inadequately controlled, giving rise to called hypersensitivity diseases, or inappropriately targeted to host tissues, causing the autoimmune diseases. In clinical medicine, the hypersensitivity diseases include the allergic or atopic diseases and the hallmarks of these diseases are the activation of TH2 cells and the production of IgE antibody. Regarding autoimmunity, at the present time we know that the key events in the development of autoimmunity are a failure or breakdown of the mechanisms normally responsible for maintaining self-tolerance in B lymphocytes, T lymphocytes, or both, the recognition of self-antigens by autoreactive lymphocytes, the activation of these cells to proliferate and differentiate into effector cells, and the tissue injury caused by the effector cells and their products. Melatonin treatment has been investigated in atopic diseases, in several animal models of autoimmune diseases, and has been also evaluated in clinical autoimmune diseases. This review summarizes the role of melatonin in atopic diseases (atopic dermatitis and asthma and in several autoimmune diseases, such as arthritis rheumatoid, multiple sclerosis, systemic lupus erythematosus, type 1 diabetes mellitus, and inflammatory bowel diseases.

    Full Text Available Introduction. Atopic dermatitis (AD is a chronic dermatological disease of multifactorial pathogenesis with persistent pruritus and extreme skin dryness including typical skin changes caused by many interactions between genetic and environmental factors. The study aims to evaluate the selected aspects of quality of life in AD. Material and methods. To what extent does the disease affect the daily practice of the patient and their family, what are their expenditures in connection with the treatment, and also how they perceive themselves and emotional, sexual, social behavior. 71 adult subjects 48(68% women and 23 (32% men were selected from the allergology clinics in the region of Silesia for this questionnaire based study. Results. Pruritus was felt by everyone, skin pain by 69%, and skin burning by 86%. The great majority of subjects had some constrains in doing housework due to skin complaints. The disease also affected professional work and school achievements. Almost everyone agreed that money spent on medication purchase and skin care agents impacted on financial resources. Atopic dermatitis affected 75% in social functioning, leisure time, sports practicing. The disease affected self-esteem level and confidence. Half of the examined subjects experienced bad feelings in contact with a partner, or felt stigmatized by negative reactions of the environment because of the skin appearance. Often atopic dermatitis caused problems with sound sleep (65% various emotional disorders and also disorders in the sexual sphere (32%. Every fourth subject felt depressed and every seventh thought of suicide. Conclusions. Atopic dermatitis is a disease which adversely influences many aspects of life and undoubtedly impairs the quality of life in a serious and distressing way. Therefore its treatment should be supported by psychotherapy.

    Full Text Available Problem statement: Atopic diseases, including asthma, eczema and allergic rhinitis, are characterized by a chronic inflammatory reaction mediated by T helper 2 cells, while type 1 diabetes mellitus is mediated by T helper 1 cells. Approach: The aim of this study was to compare the prevalence of atopic dermatitis between children with type 1 diabetes mellitus and age-matched controls. We conducted a case-control study enrolling 150 cases with type 1 diabetes mellitus between 2-20 years from pediatric endocrine out patient clinic and 450 controls randomly selected from the general population matched on sex and age. The diagnosis of atopic dermatitis was determined for patients and controls by the Hanifin and Rajka’s diagnostic criteria. Results: From 150 cases, 75 (50% were male and 75 (50% were female, with the age between 2 and 20 and among the 450 controls, 228 were male (50. 66% and 222 were female (49.33% the age was as the case. Dermatitis past or present, was identified in 1.3% of cases and 3.1% of controls, a difference which was not statistically significant (P>0.05. Conclusion: In present study, the prevalence of atopic dermatitis was comparable in diabetic children and the controls which may be due to difference between races and geographic areas and lack of support for an inverse relationship between the Th2-mediated atopy and th1-mediated autoimmune disorder. Further studies are needed to show the difference in serum IgE and cytokine profiles between the groups.

  15. Atopic dermatitis in infants and children in India

    Directory of Open Access Journals (Sweden)

    Dhar Sandipan

    2010-01-01

    Full Text Available Atopic dermatitis (AD is a chronic relapsing eczematous skin disease characterized by pruritus and inflammation and accompanied by cutaneous physiological dysfunction, with a majority of the patients having a personal or family history of "atopic diathesis." The term "atopic diathesis" refers to the presence of allergic rhinitis, bronchial asthma or AD. The universal occurrence of AD is no longer debated. However, published material about its natural history, etiopathogenesis, epidemiology, clinical patterns and management leave a lot to be known in the Indian scenario. In the present write-up, we will try to explore the wealth of knowledge about the disease available in our country and try to unfurl the complex interplay of different factors that are implicated for the development of this condition. The diagnosis of AD is based on a constellation of signs and symptoms. There is no laboratory "gold standard" for the diagnosis of AD. In a majority of the cases, the diagnosis is quite easy. Topical corticosteroids form the mainstay of topical treatment and, along with emollient, are able to control the condition in more than 80% of the cases. However, as use of long-term topical corticosteroid has the potential to produce local and systemic adverse effects, topical tacrolimus has come up as a useful molecule for the long-term control of the disease.

    Full Text Available OBJECTIVE: Atopic dermatitis (AD is a chronic inflammatory disease causing intense pruritus, and with typical clinical features. There are few epidemiological studies concerning AD in adults, as well as little information about its prognostic. The aim of this study was to evaluate the clinical and epidemiological course of adults with AD. METHODS: 80 patients aged above 18 years (mean age = 29 years were selected (30 males and 50 females and interviewed about hospitalization, systemic corticoid usage, age of AD onset, and personal and/or familial history of atopy. Disease severity was evaluated through the Scoring Atopic Dermatitis (SCORAD tool. Laboratory examination included IgE serum levels and eosinophil blood count. RESULTS: 71 out of 80 patients referred association with respiratory symptoms (18 had asthma, 17 had rhinitis, and 36 had both conditions; nine out of 80 patients denied any respiratory disease. AD patients were divided in mild (n = 25, moderate (n = 30, and severe (n = 25; 56% had one or more hospitalizations due to AD. A positive association was found between IgE serum levels, eosinophil blood count, and disease severity. CONCLUSION: Adult AD represents a clinical challenge that needs to be better characterized, since it can be misdiagnosed and interferes with the patient's social and personal life. The association of skin and respiratory atopic disease is frequent, and laboratory parameters such as circulating IgE levels and eosinophil blood count may be helpful to assess disease severity.

    Full Text Available Background Atopic dermatitis is the first manifestation of allergic disease in early life. Early interventions may prevent the development of allergy disease. Allergy trace cards have been used to identify the level of allergic risk, based on family atopy scores. Because environmental factors may also influence the development of atopic dermatitis, the usefulness of the allergy trace card needs to be reevaluated. Objective To compare the incidence of atopic dermatitis in infants aged 0-4 months with total family atopy scores of > 0 to those with scores of 0. Methods We conducted this cohort study from June 1, 2012 to December 31, 2012 at Sanglah Hospital, Denpasar. Family atopy score was tabulated from all pregnant woman in the Obstetric Outpatient Clinic and the Maternity Room. Subjects were divided into two groups based on their total family atopy score: those with scores > 0 and those with scores of 0. The appearance of atopic dermatitis symptoms in the infants were evaluated until they reached 4 months of age. The incidence of atopic dermatitis in two groups was compared using Chi-square test. Results The incidence of atopic dermatitis in this study was 10.9%. The group with total family atopy scores of 0 had a significantly higher incidence of atopic dermatitis than the group with scores > 0 (adjusted RR 22.5; 95%CI 8.8 to 57.0; P = 0.001. Conclusion The incidence of atopic dermatitis is higher in infants with total family atopy score > 0 and this group has a 22.5 times higher risk of atopic dermatitis compared to infants with total family atopy score of 0. Allergy trace cards are relevant in differentiating the risk of atopy with regards to development of atopic dermatitis. We suggest that family atopy scores be evaluated during antenatal care in order to limit the development of atopic dermatitis in infants. [Paediatr Indones. 2014;54:330-7.].

We have developed a culture-independent method for analyzing cutaneus Malassezia load in patients with atopic dermatitis.Materials and Methods: The diversity of Malassezia flora in Turkish patients with atopic dermatitis of three different clinical severities (mild, moderate, and severe were compared using quantitative real time polymerase chain reaction (qRT-PCR method. Fourthy-seven individuals with AD and seventy-five adult healthy individuals were sampled in this study. Skin samples were collected by stripping the face and neck of each subject. Fungal DNA extraction was performed and the detection of Malassezia DNA by real-time PCR was conducted. Results: Total number of patients was 122, including 47 patients and 72 healthy controls (62 female, 60 male. Quantitative analysis of Malassezia colonization in the AD group and healthy control group was not significantly different between the AD and healthy control groups. In patients with severe AD, Malassezia colonization was not different that in mild and moderate AD patients and healthy individuals, and the differences among them were not statisticaly significant (p=0.409.Conclusion: We could not find any difference in our patient group in terms of Malassezia colonization rate, although we had hypothesized. We could not show a fungal factor for the severity of the disease in AD patients. Japanese authors showed such a kind of relationship in the past. Besides, skin diseases should be evaluated carefully for the presence of microorganisms as an important factor of pathogenesis of the disease. (Turk­derm 2011; 45: 206-9

    Full Text Available Atopic dermatitis, perhaps more than other dermatologic diseases, has garnered much attention in the realm of alternative medicine. This may be because its etiopathogenesis is incompletely understood, it is increasingly common, and it waxes and wanes often without clear precipitants, opening up many opportunities for misinterpretation. Herein we explore the evidence for a number of different alternative and complementary therapies, from textiles to vitamin supplements. By definition, none have enough data to be deemed “effective” in a conventional sense, but it is hopeful that some show promising evidence that may one day lead to mainstream acceptance with further research.

    Eczema, frequently named atopic dermatitis, is the most frequent chronic skin disease of early childhood, with a high prevalence in industrialized countries and a relapsing-remitting course that is responsible for a serious burden on affected children and their families. Even though most facets of this disease are nowadays well known and numerous guidelines are available, some confusion still exists regarding certain aspects. First, several names have been proposed for the disorder. We suggest that the name and definition adopted by the World Allergy Organization should be used: 'eczema,' divided into 'atopic,' when an allergic sensitization can be demonstrated, and 'non-atopic,' in the absence of sensitization. Several diagnostic criteria have been proposed, but at present the two most reliable are the 2003 revision by the American Academy of Dermatology of the Hanifin-Rajka criteria, and those by Williams revised in 2005. To date, 20 different clinical scores have been published to assess the severity; however, only the EASI (Eczema Area and Severity Index), the SCORAD (SCORing Atopic Dermatitis), and the POEM (Patient-Oriented Eczema Measure) seem to have been adequately validated and are recommended for use in clinical practice and trials. The diagnostic tests to identify associated allergy or sensitization include skin-prick tests, determination of the specific IgE in serum using different assays, and atopy patch tests; in the case of suspected food allergy, a food challenge may be necessary to define the diagnosis. To evaluate quality of life, tools exist that allow both the child's and family's impairment to be considered. In addition, several algorithms exist to help decide therapy on a step-wise basis. However, such guidelines and algorithms represent only an aid to the physician and not an obligatory directive, since the ultimate judgment regarding any therapy must be performed by the physician and tailored to individual needs.

    Studies of the prevalence of atopic dermatitis (AD) have provided insights into associated environmental risk factors, demonstrating the complex interactions between the presence of filaggrin (FLG) gene defects and environment. Among other important findings is that elevated transepidermal water loss (TEWL) in newborns is a strong predictor of AD, regardless of FLG status. Recently recognized predictors of disease course and severity include onset of AD signs and symptoms before 12 months of age and the presence of an FLG mutation and concomitant immunoglobulin E sensitization early in life.

    Full Text Available Background: A few reports demonstrate the comorbidity of food allergy and allergic march in adult patients. Aims and Objectives: To evaluate, if there is some relation in atopic dermatitis patients at the age 14 years and older who suffer from food allergy to common food allergens to other allergic diseases and parameters as bronchial asthma, allergic rhinitis, duration of atopic dermatitis, family history and onset of atopic dermatitis. Materials and Methods: Complete dermatological and allergological examination was performed; these parameters were examined: food allergy (to wheat flour, cow milk, egg, peanuts and soy, the occurrence of bronchial asthma, allergic rhinitis, duration of atopic dermatitis, family history and onset of atopic dermatitis. The statistical evaluation of the relations among individual parameters monitored was performed. Results: Food allergy was altogether confirmed in 65 patients (29% and these patients suffer significantly more often from bronchial asthma and allergic rhinitis. Persistent atopic dermatitis lesions and positive data in family history about atopy are recorded significantly more often in patients with confirmed food allergy to examined foods as well. On the other hand, the onset of atopic dermatitis under 5 year of age is not recorded significantly more often in patients suffering from allergy to examined foods. Conclusion: Atopic dermatitis patients suffering from food allergy suffer significantly more often from allergic rhinitis, bronchial asthma, persistent eczematous lesions and have positive data about atopy in their family history.

    Full Text Available Background: N-acetylcysteine (NAC is the choice treatment for acetaminophen overdose. The main side effect of intravenous NAC therapy is anaphylaxis or anaphylactoid reactions. We investigated the prevalence of anaphylactoid or anaphylaxis reactions to IV-NAC therapy in acetaminophen poisoned patients with atopic disease. Methods: A case series antrograde and descriptive–analytic study was done on acetaminophen poisoned patients who treated with IV-NAC from September 2003 to September 2004 in Isfahan, Iran. Results: Of 173 infused IV-NAC patients, 77 patients (44.5% developed an anaphylactoid reaction. Its side effects was nausea and vomiting (n=49, 63.15%, flashing (n=23, 30.26%, bronchospasm (n=20, 26.31%, vertigo (n=18, 23.68%, skin rash (n=25, 32.36% and hypotension (n=12, 15.75%. Also, 71 patients (41% had history of atopic disease. Atopic diseases were asthma (n=12, 6.9%, atopic dermatitis (n=7, 4%, allergic rhinitis (n=5, 2.8% and allergic conjunctivitis (n=1, 0.5%. Among 71 atopic patients, 59 patients (83.13 % developed side effects to NAC. There was a relation between previous history of atopic disease and anaphylactoid reaction to NAC. Conclusions: We report substantially higher incidence of anaphylactoid reactions to IV-NAC than previous studies. Different atopic diseases must be considered as a risk factor in the development of side effects to IV-NAC-therapy.

    2014-06-01

    The purpose of this review was to identify whether supplementation with prebiotics and/or probiotics help prevent the development or reduce the severity of atopic dermatitis in children less than three years of age. Since 1997, immunostimulatory supplements, such as prebiotics and probiotics, have been investigated. Various supplementations include probiotics (single strain or mix), probiotics with formula, probiotics mix with prebiotics, and prebiotics. In this narrative review, we examined 13 key articles on prebiotics and/or probiotics, and their effects on infant atopic dermatitis. Among the selected studies, a total of 3,023 participants received supplements or placebo. Eight out of the 13 (61.5%) studies reported a significant effect on the prevention of atopic dermatitis after supplementation with probiotics and/or prebiotics. Five out of the 13 (38.5%) studies indicated significant reduction in the severity of atopic dermatitis after supplementation. Based on the available studies, supplementation with certain probiotics (Lactobacillus rhamnosus GG) appears to be an effective approach for the prevention and reduction in severity of atopic dermatitis. A mix of specific probiotic strains prevented atopic dermatitis among infants. Based on studies with prebiotics, there was a long-term reduction in the incidence of atopic dermatitis. Supplementation with prebiotics and probiotics appears useful for the reduction in the severity of atopic dermatitis. Additional interventional studies exploring prebiotics and probiotics are imperative before recommendations can be made.

    Atopic dermatitis is a common skin disorder of unknown aetiology with peak incidence in early childhood. The disease is associated with peripheral T-cell accumulation in the skin. The thymus is a key organ of the cellular immune response early in life. We hypothesized that atopic dermatitis...... is associated with an unbalanced establishment of the peripheral T-lymphocyte system. This cross-sectional study was performed to compare thymus sizes in patients with atopic dermatitis and healthy controls. Thirty-seven children with current atopic dermatitis were enrolled and compared with 29 healthy controls....... An interview and medical examination were performed by one doctor, an ultrasound scan was performed within 3 days of the examination, and the thymus index, a marker of thymus size, was measured.

    Full Text Available Background and Design: Atopic dermatitis is a chronic, inflammatory skin disease characterized by itchy skin lesions. Since adolescents are intensely interested in their physical appearance, chronic skin diseases in this period can adversely affect the development of self esteem. Atopic dermatitis is a skin disease that affects the appearance and there is an heightened attention to the body image in adolescence which is an important period of time in the development of self-esteem. Therefore, we aimed to investigate self-esteem and dermatological quality of life in adolescents with atopic dermatitis. Materials and Methods: Thirty-three patients with atopic dermatitis and 33 healthy controls were included in the study. The Piers-Harris Children’s Self-Concept Scale and the Children’s Dermatology Life Quality Index (CDLQI were used for determining self-esteem and quality of life. The Scoring of Atopic Dermatitis (SCORAD Index was used to assess the severity of atopic dermatitis. Results: It was found that patient group had lower self-esteem than healthy controls according to the Piers-Harris Children’s Self-Concept Scale. A statistically significant difference was observed in happiness/satisfaction and anxiety subscale scores between the patients and healthy controls while there was no significant difference between the other sub-scale scores. Mean value of dermatological quality of life in patients with atopic dermatitis was significantly lower than in healthy controls. A moderate negative correlation was found between self-esteem and CDLQI scores among adolescents with atopic dermatitis. Discussion: This study results have shown that self-esteem and dermatological quality of life were adversely affected in adolescents with atopic dermatitis irrespective of gender. These patients should be examined psychiatrically besides dermatological examination and treatment. We suggest that improvement will be observed in self-esteem and quality of

    Full Text Available Annalisa Patrizi, Beatrice Raone, Giulia Maria RavaioliDepartment of Specialized, Diagnostic and Experimental Medicine, Division of Dermatology, University of Bologna, Bologna, ItalyAbstract: Atopic dermatitis (AD is a common chronic inflammatory skin disease that can affect all age groups. It is characterized by a relapsing course and a dramatic impact on quality of life for patients. Environmental interventions together with topical devices represent the mainstay of treatment for AD, in particular emollients, corticosteroids, and calcineurin inhibitors. Systemic treatments are reserved for severe cases. Phototherapy represents a valid second-line intervention in those cases where non-pharmacological and topical measures have failed. Different forms of light therapy are available, and have showed varying degrees of beneficial effect against AD: natural sunlight, narrowband (NB-UVB, broadband (BB-UVB, UVA, UVA1, cold-light UVA1, UVA and UVB (UVAB, full-spectrum light (including UVA, infrared and visible light, saltwater bath plus UVB (balneophototherapy, Goeckerman therapy (coal tar plus UVB radiation, psoralen plus UVA (PUVA, and other forms of phototherapy. In particular, UVA1 and NB-UVB have gained importance in recent years. This review illustrates the main trials comparing the efficacy and safety of the different forms of phototherapy. No sufficiently large randomized controlled studies have been performed as yet, and no light modality has been defined as superior to all. Parameters and dosing protocols may vary, although clinicians mainly refer to the indications included in the American Academy of Dermatology psoriasis guidelines devised by Menter et al in 2010. The efficacy of phototherapy (considering all forms in AD has been established in adults and children, as well as for acute (UVA1 and chronic (NB-UVB cases. Its use is suggested with strength of recommendation B and level of evidence II. Home phototherapy can also be performed

  19. Respiratory infections in adults with atopic disease and IgE antibodies to common aeroallergens.

    Directory of Open Access Journals (Sweden)

    Aino Rantala

    Full Text Available BACKGROUND: Atopic diseases, including allergic rhinitis, allergic dermatitis and asthma, are common diseases with a prevalence of 30-40% worldwide and are thus of great global public health importance. Allergic inflammation may influence the immunity against infections, so atopic individuals could be susceptible to respiratory infections. No previous population-based study has addressed the relation between atopy and respiratory infections in adulthood. We assessed the relation between atopic disease, specific IgE antibodies and the occurrence of upper and lower respiratory infections in the past 12 months among working-aged adults. METHODS AND FINDINGS: A population-based cross-sectional study of 1008 atopic and non-atopic adults 21-63 years old was conducted. Information on atopic diseases, allergy tests and respiratory infections was collected by a questionnaire. Specific IgE antibodies to common aeroallergens were measured in serum. Adults with atopic disease had a significantly increased risk of lower respiratory tract infections (LRTI; including acute bronchitis and pneumonia with an adjusted risk ratio (RR 2.24 (95% confidence interval [CI] 1.43, 3.52 and upper respiratory tract infections (URTI; including common cold, sinusitis, tonsillitis, and otitis media with an adjusted RR 1.55 (1.14, 2.10. The risk of LRTIs increased with increasing level of specific IgE (linear trend P = 0.059. CONCLUSIONS: This study provides new evidence that working-aged adults with atopic disease experience significantly more LRTIs and URTIs than non-atopics. The occurrence of respiratory infections increased with increasing levels of specific IgE antibodies to common aeroallergens, showing a dose-response pattern with LRTIs. From the clinical point of view it is important to recognize that those with atopies are a risk group for respiratory infections, including more severe LRTIs.

  20. Altered cutaneous expression of beta-defensins in dogs with atopic dermatitis.

    Canine atopic dermatitis (AD) is a chronic allergic skin disorder with an immunopathogenesis comparable to that in humans with AD. The high frequency of recurrent infections with Staphylococcus pseudo intermedius and Malassezia pachydermatis may indicate a defective innate immune response in the skin of atopic dogs. Production of beta-defensins constitutes an important role in skin defense but information on canine beta-defensin localization and regulation is scarce. We conducted a gene-expression study of 16 canine beta-defensins (cBDs) in 11 tissues of healthy dogs, which revealed a variable expression of cBDs in different organ systems of the dog. In skin, three beta-defensins, cBD1, cBD103 and cBD107, were extensively expressed, while inconsistent expression of five other beta-defensins was detected. Using immunohistochemistry abundant expression of cBD103 peptide was detected in the epidermis, hair follicles and sebaceous glands, comparable to hBD3 expression in human skin. To examine the gene-expression of beta-defensins in atopic dogs, full thickness skin biopsy specimens (non-lesional and lesional) of 10 atopic dogs and 7 healthy dogs were examined with real-time PCR. A significant 12-fold increased expression of cBD1 was detected in lesional atopic skin compared to healthy skin, while non-lesional skin showed a 5-fold increase. Contrary to cBD1, expression of cBD103 was slightly (2-fold) downregulated in skin of atopic dogs. Gene-expression levels of S100A8, a marker for atopic dermatitis, were also highly upregulated in skin of atopic dogs, confirming the diagnostics of the skin biopsies. Taken together these results provide new evidence for a possible defect in the innate immune response of dogs with atopic dermatitis, and indicate the potential of the dog as a model for human AD.

  1. Changes of epidermal mu-opiate receptor expression and nerve endings in chronic atopic dermatitis.

    There is increasing evidence that neuropeptides such as a substance P, neurotrophins or beta-endorphin, an endogenous agonist for mu-opioid receptor, are involved in the pathogenesis of atopic dermatitis in which mental stress and scratching deteriorate the disease. mu-Opioid receptor, a G-protein-coupled receptor, can be downregulated and internalized by agonists and other factors in vitro. In this study, we investigated the regulation of mu-opioid receptor and nerve endings in atopic dermatitis patients. Skin biopsies from atopic dermatitis patients revealed a significant downregulation of mu-opiate receptor expression in epidermis of atopic dermatitis. Permeabilization of the skin showed that the receptor in keratinocytes from atopic dermatitis is internalized. The mRNA expression pattern of the mu-opiate receptor is different in epidermis taken from patients with chronic atopic dermatitis compared to normal skin. In atopic dermatitis, the mRNA is concentrated in the subcorneal layers of the epidermis and in normal skin in the suprabasal layers. Staining of the nerve endings using protein gene product 9.5 shows a different pattern of epidermal nerve endings in normal skin compared to atopic dermatitis. In normal skin, the epidermal nerve endings are rather thick. However, in atopic dermatitis, the epidermal nerve endings are thin and run straight through the epidermis. Based on these observations and combining the 'intensity' and 'pattern' hypothesis, we propose a new theory especially for histamine-unrelated, peripheral induction of chronic pruritus. We suggest that 'itch' is elicited in the epidermal unmyelinated nerve C-fibers and 'pain' in the dermal unmyelinated nerve fibers. The downregulation of the opioid receptor in the epidermis contributes to the chronic itching. We call this new hypothesis the 'layer hypothesis'.

    We measured the concentration of interferon-gamma and interleukin-4 in the exhaled breath condensate of children with atopic and nonallergic dermatitis receiving a probiotic supplementation (Lactobacillus reuteri ATCC 55730) or placebo for 8 weeks. We demonstrated that the levels of these cytokines increased and decreased respectively only in atopic subjects receiving active treatment. Our data suggest that the oral administration of a specific probiotic strain in patients with atopic dermatitis can modulate in vivo the cytokine pattern at a different site from intestine.

    Atopic dermatitis is the most common chronic inflammatory skin disease. Its pathogenesis combines barrier defects, immune dysregulation, and increased skin infections; however, the relative contribution of each of these components is yet to be determined. Uninvolved atopic dermatitis skin also displays broad immune and barrier abnormalities, which highlights a role for proactive treatment strategy. The residual disease genomic profile that accompanies clinical resolution provides further support for proactive treatment approaches. Although intrinsic and extrinsic atopic dermatitis subtypes share a common clinical phenotype, they show some important differences in their Th22/Th17 cytokine profile, which opens the door for personalized specific therapeutics for each disease category.

    Atopic dermatitis can be due to a variety of causes from nonatopic triggers to food allergy. Control of egress of water and protection from ingress of irritants and allergens are key components of cutaneous barrier function. Current research suggests that a degraded barrier function of the skin allows the immune system inappropriate access to environmental allergens. Epidermal aeroallergen exposure may allow sensitization to allergen possibly initiating the atopic march. Further research into connections between epidermal barrier function and possible allergen sensitization will be important to undertake. Future clinical trials focused on skin barrier protection may be of value as a possible intervention in prevention of the initiation of the atopic march. PMID:22619686

    There are increasing numbers of education programmes for children and young people with atopic dermatitis. These also include directions for the treatment of atopic dermatitis. However, the methods to be followed and the treatment to be applied are usually not clearly defined or explained. Presented are the key aspects of the local treatment of atopic dermatitis to be taught to children. The introduction of a basic therapeutic concept helps sort out which are the best preparations to use, some with and others without active ingredients. The interactions between basic care, active ingredients and skin conditions are explained in such a way that children can understand them.

    Detergent enzymes may cause skin irritation and occasionally hypersensitivity reactions. The potential hazards of these enzymes have led some physicians to advise atopic dermatitis patients against the use of enzyme-enriched detergents. A three-phased randomised, double-blind, cross-over experiment...... statistical differences in any of the primary or secondary parameters comparing treatment and placebo periods. Our data therefore seem to exclude that atopic dermatitis may exacerbate during 1 month's exposure to enzyme-enriched detergents. Since no significant irritant capacity was detected in atopic...... dermatitis patients, it is unlikely that consumers with "normal skin" will experience any skin discomfort when enzyme-enriched detergents are used....

    mutations may influence skin pH. OBJECTIVE: We aimed to determine the epidermal pH in different groups stratified by filaggrin mutations and atopic dermatitis. Further, we investigated the changes in pH according to severity of mutational status among patients with dermatitis, irrespective of skin condition....... METHODS: pH was measured with a multiprobe system pH probe (PH 905), and the study population was composed of 67 individuals, who had all been genotyped for 3 filaggrin mutations (R501X, 2282del4, R2447X). RESULTS: We found no clear pattern in relation to filaggrin mutation carrier status. Individuals...... with wild-type filaggrin displayed both the most acidic and most alkaline values independent of concomitant skin disease; however, no statistical differences between the groups were found. CONCLUSIONS: The lack of significant diversity in skin pH in relation to filaggrin mutation carrier status suggests...

    Coxsackievirus A6 (CV-A6) is an emerging pathogen that has in recent years been associated with atypical hand, foot and mouth disease. This manifests as a generalized papular or vesicular eruption, which may be associated with fever and systemic disturbance. We report a series of six children presenting to a single centre in the UK with disseminated CV-A6 infection on a background of atopic dermatitis (AD). Our patients exhibited a widespread papular or vesicular eruption in association with exacerbation of AD. Several of our cases mimicked eczema herpeticum, but the extent was more generalized, and individual lesions were discrete rather than clustered and were less circumscribed in character. This series highlights that CV-A6 infection may be encountered in the UK, and should be considered in the differential diagnosis of an acute exacerbation of AD, particularly in children.

    The newer and emerging treatments for atopic dermatitis (AD) focus on blockade of inflammatory cytokines, especially those that derive from T helper cell type 2 (TH2) and are associated with a pathway of immunoglobulin E (IgE) sensitization. Among the proinflammatory cytokines that have been identified as promising therapeutic targets are chemoattractant receptor-homologous molecule expressed on TH2 cells (CRTH2), IgE, thymic stromal lymphopoietin (TSLP), and several monoclonal antibodies that block key cytokine pathways in the innate immune response. Two agents that have been studied in phase III clinical trials are the boronbased phosphodiesterase-4 (PDE-4) inhibitor, crisaborole, and dupilumab, an antibody that inhibits the interleukin-4/ IL-13 receptor α chain.

    Colloidal oatmeal suspensions are currently available in bath soaps, shampoos, shaving gels, and moisturizing creams, and several studies have been conducted that demonstrate the efficacy and safety of colloidal oatmeal for the treatment of inflammatory skin conditions. The diverse chemical polymorphism of oats translates into numerous clinical utilities for atopic dermatitis (AD) and eczema. Avenanthramides are the principle polyphenolic antioxidants in oats, and they have been shown to assuage inflammation in murine models of contact hypersensitivity and neurogenic inflammation and also reduce pruritogen-induced scratching in a murine itch model. Moreover, avenanthramides are a potent antioxidant. This paper will discuss various studies that have found colloidal oatmeal compounds to be beneficial in the treatment of AD and also as adjunctive treatments for AD. PMID:25607551

    Full Text Available Increased plasma histamine levels were associated with significantly lowered diamine and type B monoamine oxidase activities in platelet-rich plasma of atopic eczema (AE patients. The diamine oxidase has almost normal cofactor levels (pyridoxal phosphate and Cu2+ but the cofactor levels for type B monoamine oxidase (flavin adenine dinucleotide and Fe2+ are lowered. The biogenic amines putrescine, cadaverine, spermidine, spermine, tyramine and serotonin in the sera, as well as dopamine and epinephrine in EDTA-plasma were found to be normal. It is unlikely, therefore, that these amines are responsible for the decreased activities of monoamine and diamine oxidase in these patients. The most likely causative factors for the inhibition of the diamine oxidase are nicotine, alcohol, food additives and other environmental chemicals, or perhaps a genetic defect of the diamine oxidase.

    2008-12-01

    Recent insights into the relevance of the epidermal barrier function and its interaction with components of the innate and adaptive immune responses in patients with atopic dermatitis (AD) give rise to a number of novel potential treatment options. In particular, the identification of loss-of-function mutations in the barrier protein filaggrin and of a diminished expression of certain antimicrobial peptides in AD skin stimulates new concepts to think beyond the T(H)1/T(H)2 paradigm. This review will focus on these most recent discoveries and will discuss new and corresponding proof-of-concept trials in patients with AD. It will further speculate on novel ways to restore the homeostasis among the 3 major components in AD skin suspected to be clinically relevant. PMID:18992925

    Full Text Available Pavel V Chernyshov Department of Dermatology and Venereology, National Medical University, Kiev, Ukraine Abstract: Atopic dermatitis (AD is one of the most common skin diseases. Prevalence of AD is highest in childhood. Because of chronicity and often visible lesions, AD may lead to stigmatization and problems with self-perception. However, problems of self-perception and stigmatization in AD children are poorly studied. Literature data on general tendencies of children’s development, clinical course, and epidemiologic tendencies of AD in different age groups make it possible to highlight three main periods in the formation of self-perception and stigmatization. The first period is from early infancy till 3 years of age. The child’s problems in this period depend on parental exhaustion, emotional distress, and security of the mother–child attachment. The child’s AD may form a kind of vicious circle in which severe AD causes parental distress and exhaustion that in turn lead to exacerbation of AD and psychological problems in children. The second period is from 3 till 10 years of age. During this period, development of AD children may be influenced by teasing, bullying, and avoiding by their peers. However, the majority of children in this age group are very optimistic. The third period is from 10 years till adulthood. Problems related to low self-esteem are characteristic during this period. It is important to identify children with AD and their parents who need psychological help and provide them with needs-based consultation and care. Appropriate treatment, medical consultations, and educational programs may help to reduce emotional problems in AD children and their parents.

    Full Text Available Kaposi’s varicelliform eruption is a widespread viral infection frequently caused by herpes simplex virus types 1 and 2, and less frequently Coxsackie A-16 and vaccinia virus superimposed on a pre-existing dermatosis. It is often associated with atopic dermatitis. The topical immunomodulator pimecrolimus have proven effective in managing atopic dermatitis. Reported adverse effects are infrequent; however, cutaneous infections are potential complications of its application. Kaposi’s varicelliform eruption is the most important problem in treating patients with atopic dermatitis with pimecrolimus. Even though the causative effect of this topical immunomodulator remains unclear, patients should be thought to recognise herpes simplex virus infection and stop application to prevent the spreading of the infection. Herein we report a child with atopic dermatitis who developed Kaposi’s varicelliform eruption during treatment with pimecrolimus because of its rare occurence

    The present study sought to determine if exposure to common childhood medical problems (i.e., infections and atopic disorders [e.g., allergies, asthma]) may dysregulate the hypothalamic-pituitary-adrenal (HPA) axis. Longitudinal data from 96 youth were used to examine this possibility. Medical records were drawn from government databases indicating the frequency of visits to healthcare facilities for infections and atopic disorders from infancy to early adolescence. During early adolescence, participants provided salivary cortisol samples from awakening until bedtime over 2 consecutive days. Individuals with a history of increased number visits for infections across childhood displayed elevated levels of cortisol at awakening whereas individuals with childhood histories of visits for atopic disorders displayed blunted diurnal cortisol slopes. These findings build on previous research documenting associations between infections and atopic disorders and cortisol by identifying longitudinal linkages from early health problems to later HPA axis functioning.

Recent investigations have shed new light on this important question, and in...... this article, we explore whether there is evidence that atopic dermatitis affects the risk of contact sensitization and allergic contact dermatitis. The use of topical products to treat xerotic and inflamed skin in atopic dermatitis often results in a higher prevalence of sensitization to, for example......, fragrances and other ingredients in emollients. Moreover, the prevalence of metal allergy seems to be increased, probably due to compromised chelation of the metals in the stratum corneum of patients with atopic dermatitis.

  9. A neural jet charge tagger for the measurement of the B$0\\atop{s}$-$\\bar{B}$$0\\atop{s}$ oscillation frequency at CDF

    Lecci, Claudia [Univ. of Karlsruhe (Germany)

    2005-07-01

    A Jet Charge Tagger algorithm for b-flavour tagging for the measurement of Δms at CDF has been presented. The tagger is based on a b-track probability variable and a b-jet probability variable, both obtained by combining the information available in b$\\bar{b}$ events with a Neural Network. The tagging power measured on data is 0.917 ± 0.031% e+SVT sample; 0.938 ± 0.029% μ+SVT sample which is ~30% larger than the cut based Jet Charge Tagger employed for the B$0\\atop{s}$ mixing analysis presented by CDF at the Winter Conferences 2005. The improved power of the tagger is due to the selection of the b-jet with a Neural Network variable, which uses correlated jet variables in an optimal way. The development of the track and jet probability has profited from studies performed on simulated events, which allowed to understand better the features of b$\\bar{b}$ events. For the first time in the CDF B group a Monte Carlo sample comprising flavour creation and additional b$\\bar{b}$ production processes has been examined and compared to Run II data. It has been demonstrated that a Monte Carlo sample with only flavour creation b$\\bar{b}$ production processes is not sufficient to describe b$\\bar{b}$ data collected at CDF. The sample with additional processes introduced in this thesis is thus essential for tagging studies. Although the event description is satisfactory, the flavour information in the Monte Carlo sample differs with respect to data. This difference needs to be clarified by further studies. In addition, the track and the jet probabilities are the first official tools based on Neural Networks for B-Physics at CDF. They have proven that the simulation is understood to such an advanced level that Neural Networks can be employed. Further work is going on in this direction: a Soft Electron and a Soft Muon Tagger based on Neural Networks are under development as of now. Several possible tagger setups have been studied and the Jet Charge Tagger reached

  19. Relevance of inhalant and food allergens to the etiology and management of patients with atopic dermatitis

    Energy Technology Data Exchange (ETDEWEB)

    Platts-Mills, T.A.; Mitchell, E.B.; Rowntree, S.; Heymann, P.W.; Chapman, M.D.

    Patients with atopic dermatitis have IgE antibodies to common environmental antigens, both foods and inhalants. Such antibodies are probably relevant and exposure to the corresponding antigens can give rise to eczema. Nevertheless, the mechanisms involved and the role of other etiologies, e.g. contact reactions, remain to be elucidated. Patients with atopic dermatitis should have comprehensive evaluations to determine the role of environmental antigens.

    Meibomian gland dysfunction (MGD) is one of the most common ophthalmologic conditions worldwide.The clinical spectrum of the disease varies.Patients with mild MGD only experience chronic discomfort.Patients with severe dysfunction experience a decrease in vision and then become blind.The pathology of MGD involves meibomian gland destruction and an increase in lipid viscosity that blocks the pore, causing a reduction in glandular lipid secretion and discharge.This leads to a lack of the lipid layer in tear film, therefore causing damage to the ocular surface epithelial cells and inflammation.The keratoconjunctivitis associated with MGD occurs at the inferior corneal area that is in contact with the palpebral margin.Corneal tissue infiltrates the blood vessels.Some patients also suffer from acne and sebaceous gland disorder.Treatment includes cleaning the palpebral margin, supple artificial tear liquid, and treatment for infection and inflammation that prevents ocular tissue damage.Systemic medicine is necessary for patients with severe conditions.Complications need to be treated in a timely manner.%睑板腺功能障碍(MGD)是临床常见的眼表疾病,患病人群大,表现多样,轻重不一.轻者仅表现为眼部不适,重者影响角膜,引起视力下降甚至失明.MGD以睑板腺终末导管的阻塞和睑脂分泌物质和量的异常为主要病理基础,使泪液稳定性下降,引起眼表上皮损伤和炎症细胞的激活,释放炎症因子.MGD相关的角膜病变通常发生在下方角膜缘与睑缘相接触的部位,角膜浸润伴有血管的长入,部分患者合并面部痤疮和其他皮脂腺异常.治疗原则为清洁睑缘、热敷及按摩以促进睑板腺的分泌和排放;补充泪液缓解症状;抗感染和抗炎药物抑制炎症反应,防治组织损伤,重度或有全身疾病者同时给予全身药物治疗;及时处理并发症.

    Full Text Available Canine Atopic Dermatitis is a skin disease of genetic origin. The affected dog becomes sensible to antigens presents in the environment, developing a severe alergic, pruriginous reaction, which intervenes in the quality of life of the patient. Because of the genetic character, that is an illness that in most of the times has no cure, just control. The treatment in general is lifetime. Thus, some used drugs, for example the corticosteroides, might cause collateral effects when used for a long time, and might decrease the lifetime of the animals. By this way, the owner of the dog with atopia, must know about the complications of the disease, and occasional return of the clinical signs during the period of treatment. Therefore, this article has an objective of a review about Canine Atopic Dermatitis that is an increasing problem in the small animal practice.A Dermatite Atópica Canina é uma dermatopatia de origem genética. Os cães acometidos tornam-se sensíveis aos antígenos presentes no meio ambiente, desenvolvendo grave reação alérgica, pruriginosa, que interferem na qualidade de vida do paciente. Devido ao seu caráter genético, esta é uma doença que na maioria das vezes não tem cura, apenas controle. O tratamento em geral é vitalício. Assim sendo, algumas drogas utilizadas, a exemplo dos corticosteróides, podem causar efeitos colaterais que em longo prazo, são capazes de diminuir o período de vida do animal. Desta maneira, o proprietário do cão portador de atopia, precisa ser esclarecido em relação às complicações e provável recidiva dos sinais clínicos, durante o período de tratamento. Portanto, presente artigo tem como objetivo uma revisão sobre Dermatite Atópica Canina, que está se tornando um problema crescente na clínica de pequenos animais.

    Introduction. The IFAP syndrome is a rare X-linked genetic disorder characterized by the triad of follicular ichthyosis, atrichia, and photophobia. Case Report. A three-month-old Caucasian, male patient was observed with noncicatricial universal alopecia and persistent eczema from birth. He had dystrophic nails, spiky follicular hyperkeratosis, and photophobia which became apparent at the first year of life. Short stature and psychomotor developmental delay were also noticed. Histopathological examination of skin biopsy on left thigh showed epidermis with irregular acanthosis, lamellar orthokeratotic hyperkeratosis, and hair follicles fulfilled by parakeratotic hyperkeratosis. The chromosomal study showed a karyotype 46, XY. Total IgE was 374 IU/mL. One missense mutation c.1360G>C (p.Ala454Pro) in hemizygosity was detected on the MBTPS2 gene thus confirming the diagnosis of IFAP syndrome. Conclusions. We describe a boy with a typical clinical presentation of IFAP syndrome and severe atopic manifestations. A novel missense mutation c.1360G>C (p.Ala454Pro) in MBTPS2 gene was observed. The phenotypic expression of disease is quantitatively related to a reduced function of a key cellular regulatory system affecting cholesterol and endoplasmic reticulum homeostasis. It can cause epithelial disturbance with failure in differentiation of epidermal structures and abnormal skin permeability barrier. However, no correlation phenotype/genotype could be established.

    Atopic dermatitis (AD) is a complicated and multifactorial disease. Autoimmune reactions to own antigens (Ag) revealed in AD patients can aggravate a clinical course of this disease. The aim of the study was to identify IgE antibodies (IgE-Abs) to tissue Ags in AD patients and to evaluate a relationship between the levels of these IgE-Abs and the level of the total IgE. Serum samples from 75 AD patients and 24 healthy persons of different age were examined with enzyme immunoassay for IgE-Abs to 7 tissue Ags (keratin, collagen of type III and VI, elastin, myosin, myelin basic protein - MBP, thyroglobulin), total IgE and IgE-Abs to exoallergens. The levels of IgE-Abs to all investigated tissue Ags (except for MBP) were higher (p collagen of type VI (r = 0.32), thyroglobulin (r = 0.78) and of total IgE. Therefore, most of stimulating IgE-autoreactivity Ags are involved in the pathologic process in AD, keratin, collagen of type IV, thyroglobulin being more important. This may aggravate an AD course.

    Full Text Available Cymbidium has known antibacterial and antiedema activity and has been used as an ingredient in cosmetics and fragrances. The effects of Cymbidium ethanol extract (CYM on allergic response and the underlying mechanisms of action have not been reported. Therefore, the purpose of this study was to determine the effect of CYM on allergic responses. Topical application of CYM was effective against immunoglobulin E (IgE/dinitrophenyl-conjugated bovine serum albumin- (DNP-BSA- induced degranulation of RBL-2H3 cells and anaphylaxis in ICR mice. An allergic dermatitis-like mouse model was used to evaluate the therapeutic potential of CYM in vivo. Continuous application of 2,4-dinitrochlorobenzene (DNCB not only induced dermatitis in ICR mice but also aggravated the skin lesioning. However, the application of CYM decreased skin lesion severity, scratching behavior, and IgE levels. In addition, CYM downregulated the expression of the proinflammatory cytokines interleukin- (IL- 4, IL-13, and tumor necrosis factor- (TNF- α. Studies of signal transduction pathways showed that CYM suppressed the phosphorylation of spleen tyrosine kinase (Syk, an upstream molecule. It also inhibited the phosphorylation of Akt, phospholipase C- (PLC- γ, and mitogen-activated protein kinase kinase kinase (MEKK. These results indicate that CYM may be effective in preventing and reducing allergic response and may have therapeutic potential as an antiallergic agent in disorders such as atopic dermatitis.

  8. Signal transduction around thymic stromal lymphopoietin (TSLP in atopic asthma

    2008-08-01

    Full Text Available Abstract Thymic stromal lymphopoietin (TSLP, a novel interleukin-7-like cytokine, triggers dendritic cell-mediated inflammatory responses ultimately executed by T helper cells of the Th2 subtype. TSLP emerged as a central player in the development of allergic symptoms, especially in the airways, and is a prime regulatory cytokine at the interface of virus- or antigen-exposed epithelial cells and dendritic cells (DCs. DCs activated by epithelium-derived TSLP can promote naïve CD4+ T cells to adopt a Th2 phenotype, which in turn recruite eosinophilic and basophilic granulocytes as well as mast cells into the airway mucosa. These different cells secrete inflammatory cytokines and chemokines operative in inducing an allergic inflammation and atopic asthma. TSLP is, thus, involved in the control of both an innate and an adaptive immune response. Since TSLP links contact of allergen with the airway epithelium to the onset and maintainance of the asthmatic syndrome, defining the signal transduction underlying TSLP expression and function is of profound interest for a better understandimg of the disease and for the development of new therapeutics.

    Subjective/objective symptoms (itching, papula, erythema, lichenification, desquamation, scratching, erosion) and the levels of IgE, LDH, interleukin (IL) -6, thymus and activation-regulated chemokine (TARC) were compared before and after administering olopatadine hydrochloride (ALLELOCK tablets) to 17 atopic dermatitis (AD) patients. Subject/objective symptoms improved significantly after administering the agent, and the total dosage of the combined topical steroids was also significantly decreased after administration (p<0.05), although IgE, IL-6 and LDH levels did not change, TARC was significantly decreased (p<0.05). The correlation between the levels of IgE, IL-6, LDH and TARC before and after the administration was examined. There was a positive correlation between IgE and TARC (r=0.62, p<0.01) and between IL-6 and TARC (r=0.78, p<0.01). Olopatadine hydrochloride is therefore useful in improving the symptoms in AD, and TARC may be used as an indicator of the symptom improvement.

  10. Histamine Modulates Sweating and Affects Clinical Manifestations of Atopic Dermatitis.

    Many factors such as food or environmental allergens, bacteria, fungi, and mental stress aggravate the condition of atopic dermatitis (AD) eczema. Sweating can also exacerbate AD, and patients are aware of that. In the past, it has been reported that contamination of skin surface antigens by sweat induces acute allergic reactions and that sweating functions of AD patients via axonal reflexes are decreased. Histamine demonstrably inhibits acetylcholine-induced sweating in both mice and humans via histamine H1 receptor-mediated signaling. In sweat glands, acetylcholine inactivates glycogen synthase kinase 3β (GSK3β), a kinase involved in endocytosis and secretion, whereas simultaneous stimulation with histamine activates GSK3β and inhibits sweat secretion. Thus, histamine might be involved in the mechanism of abnormal skin dryness in patients with AD via decreasing sweat secretion. On another front, some patients secrete sweat normally. Patients with regular sweating are prone to develop skin disorders such as papules or erythema by residual sweat left on the skin surface. Patients with decreased sweating are prone to develop disorders characterized by xerosis, lichenoid changes, prurigo by elevated skin temperature, skin dryness, and compromised skin conditions. Careful inspection of skin manifestations provides a good indication of a patient's ability to sweat. PMID:27584962

    Atopic dermatitis (AD) is the most common pediatric skin disease. AD has a significant effect on patient and family quality of life caused by intense pruritus, sleep disruption, dietary and nutritional concerns, and psychological stress associated with the disease and its management. Multidisciplinary approaches to AD care have been developed in appreciation of the complex interplay among biological, psychological, behavioral, and dietary factors that affect disease control and the wide range of knowledge, skills, and support that patients and families require to effectively manage and cope with this condition. Common components of multidisciplinary treatment approaches include medical evaluation and management by an AD specialist, education and nursing care, psychological and behavioral support, and nutritional assessment and guidance. Models of care include both clinical programs and structured educational groups provided as adjuncts to standard clinical care. Available evidence suggests beneficial effects of multidisciplinary interventions in improving disease severity and quality of life, particularly for patients with moderate-to-severe disease. Additional research is needed to identify the best candidates for the various multidisciplinary approaches and evaluate the cost-effectiveness of these programs. PMID:27497275

    The therapeutic value of regular physical exercise for patients with atopic eczema (AE) and other chronic inflammatory dermatoses has not yet been investigated systematically. At our institution an adjuvant group sports programme for voluntary inpatients has been in place for 3 years. Using a standardized questionnaire we found positive psychological influences of this program on the patients' mood and psychosocial wellbeing. Since most dermatologists, however, regard sweating as detrimental for patients with AE, we studied the impact of regular sports activities on the skin condition of AE-patients otherwise subdued to usual dermatotherapy (yet without corticosteroids) by aid of a standardized symptomscore system. Thirty inpatients with AE participated regularly in the sports programme, another 30 inpatients with AE (the control group) did not. The skin condition improved similarly the two groups over the study period of about 3 weeks. Cutaneous thermoregulation (with one arm in a 41 degrees C water bath as thermic stimulus) was examined in patients with AE before and after the study period. While many AE patients initially showed paradoxical, i.e. decreasing, skin temperature in the contralateral arm, after 3 weeks of physical training most of the participants had normalized consensual, i.e. increased, temperature reaction to the same warmth exposure. The conclusion is drawn that regular sports may be of adjuvant therapeutic value in patients suffering from AE, except in the acute stages of the disease. PMID:7822198

    Full Text Available Atopic dermatitis (AD is one of the most common infantile diseases. Immunological dysfunctions in AD patients may predispose them to infections. The aim of this study was to evaluate the relationship between infantile AD and urinary tract infection (UTI.In this cross sectional study, we enrolled 57 patients with AD aged 1 to 24 months that referred to dermatology clinic, and 57 healthy controls who were referred to pediatric clinic. The groups were matched according to age and gender. Urine samples were collected by clean-voided bag method. If a single organism was cultured at concentration of ≥105 organisms per millimeter and the existence of white blood cells more than 10 per microscopic field was seen the patients underwent suprapubic aspiration. The presence of one organism in suprapubic aspiration sample was regarded as positive culture. Data were analyzed using SPSS version 15 software. P value Infants with AD showed a higher frequency of UTI in this study. So, we suggest screening all AD infants for urinary tract infection.

    Atopic dermatitis (AD) is characterized by reduced barrier function, reduced innate immune activation, and susceptibility to Staphylococcus aureus. Host susceptibility factors are suggested by monogenic disorders associated with AD-like phenotypes and can be medically modulated. S. aureus contributes to AD pathogenesis and can be mitigated by antibiotics and bleach baths. Recent work has revealed that the skin microbiome differs significantly between healthy controls and patients with AD, including decreased Gram-negative bacteria in AD. However, little is known about the potential therapeutic benefit of microbiome modulation. To evaluate whether parameters of AD pathogenesis are altered after exposure to different culturable Gram-negative bacteria (CGN) collected from human skin, CGN were collected from healthy controls and patients with AD. Then, effects on cellular and culture-based models of immune, epithelial, and bacterial function were evaluated. Representative strains were evaluated in the MC903 mouse model of AD. We found that CGN taken from healthy volunteers but not from patients with AD were associated with enhanced barrier function, innate immunity activation, and control of S. aureus. Treatment with CGN from healthy controls improved outcomes in a mouse model of AD. These findings suggest that a live-biotherapeutic approach may hold promise for treatment of patients with AD.

    Full Text Available Background: Few studies have been done on the relation between acetylator status and allergic diseases. Aim: To determine any possible association between acetylating phenotype in pediatric patients with atopic dermatitis (AD and the disease prognosis. Patients and Methods: Thirty-six pediatric patients and forty two healthy children as a control group were participated in the study. All participants received a single oral dose of dapsone of 1.54 mg/kg body weight, after an overnight fast. Using high performance liquid chromatography (HPLC, plasma concentrations of dapsone and its metabolite (monoacetyldapsone were estimated to phenotype the participants as slow and rapid acetylators according to their acetylation ratio (ratio of monoacetyldapsone to dapsone. Results: 72.2% of pediatric patients with AD showed slow acetylating status as compared to 69.4% of control individuals. Also, 73% of AD patients with slow acetylating phenotype had familial history of allergy. The severity of AD occurred only in slow acetylator patients. The eczematous lesions in slow acetylators presented mainly in the limbs, while in rapid acetylators, they were found mostly in face and neck. Conclusion: This study shows an association between the N-acetylation phenotype variation and clinical aspects of AD.

    Atopic dermatitis (AD) is a common skin disease that greatly worsens quality of life. Thymic stromal lymphopoietin (TSLP) plays a decisive role in the development of AD. The purpose of this study is to examine whether tryptanthrin (TR) would suppress AD through the regulation of TSLP. We analyzed the effect of TR on the level of TSLP from phorbol myristate acetate/calcium ionophore A23187-activated human mast cell line, HMC-1 cells, in 2,4-dinitrofluorobenzene-induced AD-like skin lesions of NC/Nga mice, and in anti-CD3/anti-CD28-stimulated splenocytes. TR significantly suppressed the level of intracellular calcium and the production and mRNA expression of TSLP through the blockade of receptor-interacting protein 2/caspase-1/nuclear factor-κB pathway in the activated HMC-1 cells. TR also significantly suppressed the levels of histidine decarboxylase and IL-1β. Furthermore, TR ameliorated clinical symptoms in the AD model. TR significantly reduced the levels of TSLP, IL-4, IFN-γ, IL-6, TNF-α, thymus and activation-regulated chemokine, and caspase-1 in AD skin lesions. Also, TR significantly reduced the serum levels of histamine and IL-4 in the AD model. Finally, TR significantly inhibited the production of IL-4, IFN-γ, and TNF-α from the stimulated splenocytes. Taken together, TR exhibits the potential to be a therapeutic agent for AD through down-regulation of TSLP. PMID:24295961

    Atopic dermatitis (AD) is a chronic inflammatory skin disease that commonly presents during early childhood. In the last decades the prevalence of AD has increased, especially in western societies. This frequently relapsing inflammatory condition has a strong impact on the quality of life of patients and families. The recent advances in the understanding of this disease have paved the way for the development of new strategies for the prevention and treatment of AD. Among the new therapeutic options, there is increasing interest in the potential benefit of probiotic supplementation. It has been widely demonstrated that the human microbiota plays a fundamental role not only in the maintenance of intestinal homeostasis through the interaction between microorganisms and the innate immune system, but also in the microbiota-mediated development of adaptive immunity. In addition, several studies have demonstrated that probiotics are able to influence the composition of gut microbiota and may exert immunomodulatory effects. According to these promising results, the possible application of probiotics in the therapeutic management of allergic diseases has been investigated in many studies. In particular, a considerable body of literature has been published analyzing the effects of probiotics on patients with AD. In order to shed light on frequently conflicting results, we reviewed the data regarding the application of probiotics in AD, with the aim to provide a state-of-the-art assessment of the most important studies exploring the role of probiotics both in the prevention and treatment of AD.

    2014-05-01

    Full Text Available Atopic dermatitis (AD is a chronic and inflammatory disease that affects the skin of children in their early stages of life. Its aetiology remains little understood, but it is known that there is a dysfunction of the skin barrier, which facilitates the penetration of allergens/irritants into the epidermis, causing an inflammatory response with a predominance of Th2 response relative to Th1. The diagnosis is clinical and may be associated with previous and family medical history of atopies such as rhinitis and asthma. AD manifests itself through eczematous, pruritic injuries with the presence of erythema, papules, vesicles, and scales. The main differential diagnoses of AD are seborrheic dermatitis, contact dermatitis, psoriasis and scabies. The treatment is based on the education of patients and their families, plus the control of pruritus with antihistamines and of inflammation with corticosteroids or calcineurin inhibitors. Given the high prevalence and impact of AD on the quality of life of paediatric patients, early diagnosis and an individualized approach are paramount.

    2015-02-01

    Due to a broad variety of extrinsic trigger factors, patients with atopic dermatitis (AD) are characterized by complex response mechanisms of the adaptive immune system. Notably, skin colonization with Staphylococcus aureus seems to be of particular interest since not only exotoxins, but also other proteins of S. aureus can induce specific humoral and cellular immune responses which partially also correlate with the severity of AD. In a subgroup of AD patients Malassezia species induce specific IgE- and T cell-responses which has been demonstrated by atopy patch tests. Moreover, Mala s 13 is characterized by high cross-reactivity to the human corresponding protein (thioredoxin). Induction of a potential autoallergy due to molecular mimicry seems therefore to be relevant for Malassezia-sensitized AD patients. In addition, sensitization mechanisms to autoallergens aside from cross-reactivity are under current investigation. Regarding inhalant allergens, research projects are in progress with the aim to elucidate allergen-specific immune response mechanisms in more depth. For grass-pollen allergens a flare-up of AD following controlled exposure has been observed while for house dust mite-allergens a polarization towards Th2 and Th2/Th17 T cell phenotypes can be observed. These and further findings might finally contribute to the development of specific and effective treatments for aeroallergen-sensitized AD patients. PMID:25532900

  2. Correlation between atopic manifestation and lung toxicity following chest irradiation for breast cancer

    International Nuclear Information System (INIS)

    The purpose of this study was to identify the impact of atopic manifestations on the occurrence of the lung toxicity following chest irradiation for breast cancer. Collection of 1,173 patients who had undergone radiotherapy on their 1,177 chest walls or postsurgical mammary glands at 9 institutions including ours. They received treatment consecutively from December 1980 through October 2005, with which we formed the basis of this analysis. Patients with any of the following medical history were defined as having atopic manifestations (n=111): asthma, allergic rhinitis, atopic dermatitis, contact dermatitis, and allergy to food or drug. Of them, patients who were observed for at least 6 months or who suffered from lung toxicity at any time, were classified as Group A (n=85). On the other hand, patients in our institute who were observed for at least 6 months or who suffered from lung toxicity at any time regardless of atopic manifestations, were classified as Group B (n=113), and patients without any atopic manifestation were classified as Group C (n=92). Grade 3 or higher lung toxicity in National Cancer Institute, Common Toxicity Criteria for Adverse Events (NCI-CTCAE) (v 3.0), occurred in 8.2%, id est (i.e.) 7 cases, of Group A, 2.7% of Group B, and 1.1% of Group C (p=0.0293 Group C against Group A). Three cases were classified as classical pneumonitis, and the other 4 sporadic pneumonitis such as Cryptogenic Organizing Pneumonia and Chronic Eosinophilic Pneumonia. Both of the histologically proven COP and CEP patients showed atopic manifestations in our institute. The detail clinical features are described in the main text. Having atopic manifestations suggests that there may be risk of lung toxicity following chest irradiation for breast cancer. (author)

    Objective To examine whether significant differences exist between the self-reported prevalence of atopic disorders in the open population compared with physician diagnosed prevalence of atopic disorders in general practice. Methods Medline (OvidSP), PubMed Publisher, EMBASE, Google Scholar and the Cochrane Controlled Clinical Trials Register databases were systematically reviewed for articles providing data on the prevalence of asthma, allergic rhinitis and eczema in a GP setting. Studies were only included when they had a cross-sectional or cohort design and included more than 100 children (aged 0-18 years) in a general practice setting. All ISAAC studies (i.e. the open population) that geographically matched a study selected from the first search, were also included. A quality assessment was conducted. The primary outcome measures were prevalence of eczema, asthma and allergic rhinitis in children aged 0-18 years. Results The overall quality of the included studies was good. The annual and lifetime prevalences of the atopic disorders varied greatly in both general practice and the open population. On average, the prevalence of atopic disorders was higher in the open population. Conclusion There are significant differences between the self-reported prevalence of atopic disorders in the open population compared with physician diagnosed prevalence of atopic disorders in general practice. Data obtained in the open population cannot simply be extrapolated to the general practice setting. This should be taken into account when considering a research topic or requirements for policy development. GPs should be aware of the possible misclassification of allergic disorders in their practice. Key PointsEpidemiological data on atopic disorders in children can be obtained from various sources, each having its own advantages and limitations.On average, the prevalence of atopic disorders is higher in the open population.GPs should take into account the possible

    Atopic dermatitis is a common chronic skin disorder whose management is complex. Topical corticosteroids have been the mainstay of atopic dermatitis treatment for more than 50 years but have multiple side effects. Topical calcineurin inhibitors including tacrolimus and pimecrolimus are safe and efficacious in atopic dermatitis. In 2005 the FDA issued "black box" warnings for pimecrolimus cream and tacrolimus ointment because of potential safety risks, including skin cancers and lymphomas. However, these concerns are not supported by current data. Topical calcineurin inhibitors are particularly indicated for treating patients with atopic dermatitis in whom topical corticosteroid therapy cannot be employed or may cause irreversible side effects. They can be used advantageously in problem zones. A novel regimen of proactive treatment has been shown to prevent, delay and reduce exacerbations of atopic dermatitis. Therapy with topical calcineurin inhibitors should be managed by an experienced specialist and each patient should receive proper education on how to use them and what possible unwanted effects may be expected.

    Background Although the therapeutic mechanism of balneotherapy for atopic dermatitis has not been clarified, many atopic patients who visit thermomineral springs have shown clinical improvements. Objective This study was aimed to evaluate the immunomodulatory effect of thermomineral water balneotherapy on the atopic dermatitis murine model. Methods The oxazolone-induced atopic dermatitis murine model was used to evaluate the therapeutic effect of balneotherapy with Deokgu thermomineral water compared with distilled water. Histologic evaluation and confocal microscopic imaging were performed to analyze the lesional expression of cluster-of-differentiation (CD)4 and forkhead box p3 (Foxp3). Lesional mRNA expression of interleukin (IL) 33, thymic stromal lymphopoietin (TSLP), and Foxp3 was evaluated by real-time reverse transcription polymerase chain reaction. Results Compared with the distilled water bath group, confocal microscopic evaluation of CD4 and Foxp3 merged images showed increased expression of regulatory T cells in the thermomineral balneotherapy group. The lesional mRNA level of IL-33 showed a reduced trend in the thermomineral balneotherapy group, whereas the level of mRNA of Foxp3 was increased. TSLP showed a decreased trend in both distilled water and thermomineral water bath groups. There was a trend of reduced expression in lesional IL-33 mRNA but increased cell count of CD4+ Foxp3+ regulatory T cells in thermomineral balneotherapy compared with distilled water bath. Conclusion Therefore, thermomineral balneotherapy can be an effective and safe adjuvant therapeutic option for atopic dermatitis. PMID:27081266

    Atopic dermatitis is a chronic inflammatory skin disease characterized by impaired epidermal barrier function, inflammatory infiltration, extensive pruritus and a clinical course defined by symptomatic flares and remissions. The mechanisms of disease exacerbation are still poorly understood. Clinical occurrence of atopic dermatitis is often associated with psychological stress. In response to stress, upregulation of neuropeptide mediators in the brain, endocrine organs, and peripheral nervous system directly affect immune and resident cells in the skin. Lesional and non-lesional skin of patients with atopic dermatitis demonstrates increased mast cells and mast cell-nerve fiber contacts. In the setting of stress, sensory nerves release neuromediators that regulate inflammatory and immune responses, as well as barrier function. Progress towards elucidating these neuroimmune connections will refine our understanding of how emotional stress influences atopic dermatitis. Moreover, psychopharmacologic agents that modulate neuronal receptors or the amplification circuits of inflammation are attractive options for the treatment of not only atopic dermatitis, but also other stress-mediated inflammatory skin diseases.

    The paper refers to the recently published empirical data and systematic reviews on the impact of diets, foods, nutrients and bioactive substance exposures in pregnancy and in early infancy, on the development of atopic disorders. The results of studies referring to a broad range on dietary factors are mostly conflicting. There are several limitations of these researches. Based on the existing information, it is not possible to establish the role of antioxidants and vitamin D supplementation in atopic disease development. There is no evidence of major effects of prenatal use of folic acid on asthma or allergies. The association of some nutritional interventions with less atopic sensitization seems rather speculative even if such an effect has not been found for some other foods. The findings indicate rather a balanced and diverse diet without restrictions than a special dietary protocol. Farming-related exposures may protect against the development of atopic disorders in children. The hypothesis that the early introduction of complementary food, including the potentially allergenic foods, may reduce the risk of food allergy and atopic dermatitis is currently tested. Long-chain polyunsaturated fatty acids and probiotics seem to be promising candidates for allergy prevention. But specific recommendations regarding pre- and postnatal supplementation strategies, dose, treatment duration etc., are still undetermined. Longitudinal intervention studies in cohorts of pregnant women or newborn infants are needed to match the proper strategies in these issues. PMID:27416628

    Atopic dermatitis (AD) is an inflammatory skin disease commonly affecting children and managed by pediatricians, primary care physicians, allergists, and dermatologists alike. For many years, the only available topical pharmacological treatment was topical corticosteroids. This changed in 2000-2001, when topical formulations of two calcineurin inhibitors (tacrolimus and pimecrolimus) were approved for short-term or chronic intermittent treatment of AD in patients ≥ 2 years of age, in whom other treatments have been ineffective or contraindicated. These topical calcineurin inhibitors (TCIs) quickly became a popular treatment option due at least in part to concerns over adverse events associated with prolonged topical corticosteroid use, especially in children. However, based on theoretical concerns about a possible risk of lymphoma associated with TCI use, a Boxed Warning was placed on both products in 2006. Since then, despite an extensive body of evidence, no causal relationship has been demonstrated between TCI use and an increased risk of lymphoma; however, the US FDA has concluded that a link cannot be ruled out. In fact, based on post-marketing surveillance of spontaneous, literature, and solicited reports, we report here that the lymphoma incidence in the topical pimecrolimus-exposed population is up to approximately 54-fold less than that seen in the general US population. This review summarizes the mechanism of action of TCIs, the factors that prompted the Boxed Warning, and recent TCI safety and efficacy data. Based on these data, both topical corticosteroids and TCIs should have defined roles in AD management, with TCIs favored for sensitive skin areas (e.g., face) and instances where topical corticosteroids have proven ineffective, thereby minimizing the risk of adverse effects with both drug classes.

    2016-01-01

    Atopic dermatitis (AD) is one of the most common skin diseases. Prevalence of AD is highest in childhood. Because of chronicity and often visible lesions, AD may lead to stigmatization and problems with self-perception. However, problems of self-perception and stigmatization in AD children are poorly studied. Literature data on general tendencies of children’s development, clinical course, and epidemiologic tendencies of AD in different age groups make it possible to highlight three main periods in the formation of self-perception and stigmatization. The first period is from early infancy till 3 years of age. The child’s problems in this period depend on parental exhaustion, emotional distress, and security of the mother–child attachment. The child’s AD may form a kind of vicious circle in which severe AD causes parental distress and exhaustion that in turn lead to exacerbation of AD and psychological problems in children. The second period is from 3 till 10 years of age. During this period, development of AD children may be influenced by teasing, bullying, and avoiding by their peers. However, the majority of children in this age group are very optimistic. The third period is from 10 years till adulthood. Problems related to low self-esteem are characteristic during this period. It is important to identify children with AD and their parents who need psychological help and provide them with needs-based consultation and care. Appropriate treatment, medical consultations, and educational programs may help to reduce emotional problems in AD children and their parents. PMID:27499642

    In order to investigate whether polymorphisms of genes encoding some factors of innate and adaptive immunity play a role in the development of, or protection against atopic dermatitis (AD) and condition its severity, we genotyped 33 candidate genes and 47 single nucleotide polymorphisms (SNPs) using Custom TaqMan Array Microfluidic Cards and an ABI 7900HT analyser (Applied Biosystems, Foster City, CA, USA). The study involved 104 children with AD (29 with mild-to-moderate and 75 with severe disease; 42 girls; mean age ± SD, 5.8 ± 3.3 years) and 119 healthy controls (49 girls; mean age, 4.8 ± 3.0 years). IL10-rs1800872T, TG and MBL2-rs500737AG were all significantly more frequent among the children with AD (P = 0.015, P = 0.004 and P = 0.030), whereas IL10-rs1800896C and TC were more frequent in those without AD (P = 0.028 and P = 0.032). The VEGFA-rs2146326A and CTLA4-rs3087243AG SNPs were significantly more frequent in the children with mild/moderate AD than in those with severe AD (P = 0.048 andP = 0.036). IL10-rs1800872T and TG were significantly more frequent in the children with AD and other allergic diseases than in the controls (P = 0.014 and P = 0.007), whereas IL10-rs1800896TC and C were more frequent in the controls than in the children with AD and other allergic diseases (P = 0.0055 and P = 0.0034). These findings show that some of the polymorphisms involved in the immune response are also involved in some aspects of the development and course of AD and, although not conclusive, support the immunological hypothesis of the origin of the inflammatory lesions.

    2012-01-01

    Full Text Available Atopic dermatitis can be due to a variety of causes from nonatopic triggers to food allergy. Control of egress of water and protection from ingress of irritants and allergens are key components of cutaneous barrier function. Current research suggests that a degraded barrier function of the skin allows the immune system inappropriate access to environmental allergens. Epidermal aeroallergen exposure may allow sensitization to allergen possibly initiating the atopic march. Further research into connections between epidermal barrier function and possible allergen sensitization will be important to undertake. Future clinical trials focused on skin barrier protection may be of value as a possible intervention in prevention of the initiation of the atopic march.

    Plant extracts and isolated compounds are increasingly used in cosmetics and food supplements to improve skin conditions. We first introduce the positive plant monographs with dermatological relevance of the former German Commission E. Subsequently clinical studies with botanicals for atopic dermatitis, psoriasis, acne, condylomata acuminata and herpes simplex are discussed. The best studies have been conducted with atopic dermatitis and psoriasis patients. Mahonia aquifolium, Hypericum perforatum, Glycyrrhiza glabra and certain traditional Chinese therapies have been shown to be effective in the treatment of atopic dermatitis. Mahonia aquifolium, Indigo naturalis and Capsicum frutescens are effective treatments for psoriasis. Green tea extract and tea tree oil have been investigated in the treatment of acne. Podophyllin and green tea extract are effective treatments for condylomata acuminata. Balm mint and a combination of sage and rhubarb have been shown to be effective in the treatment of herpes simplex in proof of concept studies. PMID:20707875

    BACKGROUND: Epidermal filaggrin deficiency due to common filaggrin gene (FLG) mutations causes xerosis and strongly increases the risk of atopic dermatitis and even asthma. However, it is unknown whether xerosis independent of FLG mutations could also increase the risk of asthma. OBJECTIVE: To...... evaluate whether generalized xerosis was associated with asthma, independent of atopic dermatitis and common FLG mutations in a cross-sectional study on adult Danes. METHODS: A total of 3396 adults from the general population participated in a health examination. Lung function and serum-specific IgE levels...... association was observed between xerosis and 'allergic asthma' in men (OR 2.13; 95% CI 1.08-4.19). CONCLUSION: Our findings indicate an association between xerosis and asthma in men independent of atopic dermatitis and FLG mutations.

    Atopic dermatitis (AD) is a common disease in childhood and an important risk factor for the later development of other atopic diseases. Many publications on childhood AD use questionnaires based on information obtained in adulthood, which introduce the possibility of recall bias. In a prospective...... cohort study, recall bias was evaluated in 1,501 unselected schoolchildren (mean age 14 years) evaluated for the first time in 1995 with a standardized questionnaire combined with a clinical examination and repeated in 2010. The lifetime prevalence of AD was 34.1% including data obtained both during...... school age and 15 years later, compared with 23.6% including data only from adulthood. The most important factors for remembering having had AD in childhood were: (i) long duration of dermatitis in childhood; (ii) adult hand eczema; and (iii) concomitant atopic disease. Recall bias for childhood AD...

    Atopic dermatitis (AD) is a common chronic relapsing pruritic skin disease of dogs for which treatment has varied over time and geographical location. Recent high quality randomized controlled trials and systematic reviews have established which drugs are likely to offer consistent benefit. The International Task Force for Canine AD currently recommends a multi-faceted approach to treat dogs with AD. Acute flares should be treated with a combination of nonirritating baths and topical glucocorticoids, once an attempt has been made to identify and remove the suspected causes of the flare. Oral glucocorticoids and antimicrobial therapy must be added when needed. In dogs with chronic AD, a combination of interventions should be considered. Again, factors that trigger flares of AD must be identified and, if possible, avoided. Currently recognized flare factors include food, flea and environmental allergens, Staphylococcus bacteria and Malassezia yeast. Skin and coat hygiene and care must be improved by bathing with nonirritating shampoos and dietary supplementation with essential fatty acids. The severity of pruritus and skin lesions can be reduced with a combination of anti-inflammatory drugs. Currently, medications with good evidence of high efficacy include topical and oral glucocorticoids, and calcineurin inhibitors such as oral ciclosporin and topical tacrolimus. The dose and frequency of administration of these drugs should be tailored to each patient considering each drug's efficacy, adverse effects and cost. Allergen-specific immunotherapy should be offered, whenever feasible, in an attempt to prevent recurrence of clinical signs upon further exposure to environmental allergens to which the patient is hypersensitive.

    We demonstrate a simple and cost-effective approach to realize two combined surface features of different scales together, namely submillimeter-sized protrusion array and microwrinkles, atop a polystyrene shape-memory polymer. Two different types of protrusions, namely flat-top protrusion and crown-shaped protrusion, were studied. The array of protrusions was produced by the Indentation-Polishing-Heating (IPH) process. Compactly packed steel balls were used for making array of indents. A thin gold layer was sputter deposited atop the polymer surface right after polishing. After heating for shape recovery, array of protrusions with wrinkles on the top due to the buckling of gold layer was produced.

    2015-01-01

    Full Text Available Background: Atopic dermatitis (AD is a common dermatologic condition with a prevalence varying from 5% to 15%, and it has been rising over time. Several studies from developed countries have revealed the substantial economic burden of AD on health care budgets. There has been no research however on the cost of care of AD from India a country where health care is self-funded with no health insurance or social security provided by the government. Aim: The aim of our study was to assess prospectively the cost of care of AD in children in an outpatient hospital setting in India. Methods: A total of 40 children with AD, <10 years of age, registered in the pediatric dermatology clinic at our institute were enrolled for the study. All patients were followed-up for 6 months. Demographic information, clinical profile, severity, and the extent of AD were recorded in predesigned performa. Caregivers were asked to fill up a cost assessment questionnaire specially designed for the study. It had a provision for measuring direct, indirect, and provider costs. Results: Of the 40 patients, 37 completed the study. Mean total cost for AD was Rs. 6235.00 ± 3514.00. Direct caregiver cost was Rs. 3022.00 ± 1620.00 of which treatment cost constituted 77.2 ± 11.1%. The total provider cost (cost of consultation, nursing/paramedical staff and infrastructure was Rs. 948.00, which was 15.2% of the total cost of care and the mean indirect cost calculated by adding loss of earnings of parents due to hospital visits was Rs. 2264.00 ± 2392.00 (range: 0-13,332. The mean total cost depending on the severity of AD was Rs. 3579.00 ± 948.00, Rs. 6806.00 ± 3676.00 and Rs. 8991.00 ± 3129.00 for mild, moderate and severe disease, respectively. Conclusions: AD causes a considerable drain on the financial resources of families in India since the treatment is mostly self-funded. Cost of care of AD is high and comparable to those of chronic physical illness, such as diabetes

    The purpose of this study was to evaluate the in vivo state of both branches of the autonomic nervous system in children with chronic atopic dermatitis. In 15 patients, age 4 to 11, the following parameters were analyzed: (1) basal plasma levels of epinephrine, norepinephrine, and dopamine; (2) poststimulation (standing and i.v. furosemide administration); (3) basal urinary excretion of epinephrine, norepinephrine, and vainillin mandelic acid; (4) 30 min postfurosemide administration; (5) parotid secretory response to intraoral 0.1 m citric acid: flow rate, saliva pH, and concentrations of bicarbonate, chlorides, inorganic phosphates, total protein, and amylase activity. No differences in plasma and urinary basal levels of the catecholamines were observed. In response to standing, plasma norepinephrine from atopic children showed a greater increase than that seen in normal healthy children. From the salivary factors studied, no differences were found in parotid flow-rate, bicarbonates, chlorides, and inorganic phosphates. Protein concentration as well as amylase activity were significantly decreased in children with atopic dermatitis. These findings suggest that in atopic dermatitis, the beta-sympathetic mediated responses are impaired; on the other hand, parasympathetic mediated responses remain preserved. PMID:7086169

    2002-06-01

    We have previously shown that both atopic and normal dogs generate an IgG response to antigens of Malassezia pachydermatis. The aim of this study was to compare IgE responses to separated proteins of M. pachydermatis in 28 atopic dogs with Malassezia dermatitis and 22 clinically normal dogs using Western immunoblotting. Six different detection systems were evaluated in order to assess sensitivity and eliminate nonspecific binding and cross-reactivity. The protocol yielding the best results utilized a monoclonal mouse antidog IgE, an alkaline phosphatase conjugated goat antimouse IgG which had been passed through a canine IgG column 3 times, a chemiluminescent substrate and a digital imaging system. Proteins of 45, 52, 56 and 63 kDa were recognized by more than 50% of the atopic dog sera and thus represented major allergens. Only a minority of normal dogs showed faint IgE binding to these proteins. The results indicate that the majority of atopic dogs with Malassezia dermatitis have a greater IgE response than normal dogs, suggesting an IgE-mediated immune response may be clinically important in the pathogenesis of the disease.

    With the cooperation of 12 Maternity Hospitals we have started a prospective study to evaluate the effect of dietary and environmental measures in the development of atopic disease in "at risk" newborns. The preventive measures included: exclusive breast feeding for the first 6 months of life, soy milk supplement when breast milk is not sufficient, elimination of house dust, no smoking in the house, etc. All infants were seen at the age of 1, 3, 6, 9, 12 months and twice-a-year afterwards. 1213 babies have been enrolled. At the last follow-up of 48 months 531 children are 4 year old. The cumulative prevalence of atopic disease was 20%: 11 (2%) children developed atopic dermatitis, 69 (13%) asthma, 21 (4%) rinithis, 5 (1%) urticaria. The low prevalence of atopic disease and the trivial course of the allergic manifestations in the children who followed the preventive measures (78/444 = 18%) and the higher (28/87 = 32%) in these who did not (p < 0.01) stressed the importance of such manipulations for the prevention of atopy in "at risk" babies.

    Objectives To examine whether prenatal occupational exposures, especially to organic solvents, are associated with atopic diseases in childhood. Methods The study comprised children born in Odense or Aalborg, Denmark between 1984 and 1987. Occupational job titles were derived from questionnaires filled out by the mothers when attending midwife centres. Assessment of organic solvent exposures was based on job titles selected by occupational specialists. A follow up questionnaire to the parents provided data on medical diagnoses as well as wheezing symptoms for 7844 children aged 14–18. Multivariate logistic regression analyses were performed to estimate the cumulative risk for wheezing (early wheezing not diagnosed as asthma), asthma, hay fever, and atopic eczema during childhood by means of odds ratios (OR) and 95% confidence intervals (CI). Results Explorative analyses by maternal job titles in pregnancy showed elevated odds ratios concerning different atopic diseases for occupational groups such as “bakers, pastry cooks, and confectionary makers”, “dental assistants”, “electrical and electronic assemblers”, “sewers and embroiders”, and “bookbinders and related workers”. An excess risk ratio for hay fever (OR 2.8, CI 1.1 to 7.5) was found following maternal gestational exposure to organic solvents. Furthermore, a slightly raised odds ratio for asthma was observed in children of shift workers (OR 1.2, CI 1.0 to 1.5). Conclusion The data suggest links between certain maternal occupations during pregnancy and atopic diseases, which merits further scrutiny. However, no consistent pattern was seen across the different atopic diseases. PMID:16757508

    Full Text Available Asthma and atopic dermatitis are common allergic diseases, and their prevalence has increased in urban children. Recently, it is becoming understood that forest environment has favorable health effects in patients with chronic diseases. To investigate favorable clinical and immunologic effects of forest, we examined changes in clinical symptoms, indirect airway inflammatory marker, and serum chemokines before and after a short-term forest trip. The forest trips were performed with 21 children with asthma and 27 children with atopic dermatitis. All participating children were living in air polluted urban inner-city. We measured spirometry and fractional exhaled nitric oxide (FeNO in children with asthma and measured scoring atopic dermatitis (SCORAD index and Thymus and Activation-Regulated Chemokine (TARC/CCL17 and Macrophage-Derived Chemokine (MDC/CCL22 levels in children with atopic dermatitis before and after the forest trip. Indoor air pollutants such as indoor mold, particulate matter 10 (PM10 and total volatile organic compounds (TVOCs of each child's home and the accommodations within forest were measured. A significant increase in forced vital capacity (FVC and a significant decrease in FeNO were observed after the forest trip in children with asthma. SCORAD indices and MDC/CCL22 levels were significantly decreased after the forest trip in children with atopic dermatitis. Airborne mold and PM10 levels in indoor were significantly lower in the forest accommodations than those of children's homes; however, TVOC levels were not different between the two measured sites. Short-term exposure to forest environment may have clinical and immunological effects in children with allergic diseases who were living in the urban community.

    Patients with atopic dermatitis present with debilitating symptoms, including pruritus and subsequent excoriation, which significantly reduces their quality of life (QOL). At present, the standard therapy for atopic dermatitis constitutes a topical steroid and/or a topical immunomodulator, an emollient and an oral antihistamine, although few studies have reported the effect of this treatment regimen on QOL. The current study aimed to verify the efficacy of the standard therapy for both clinical symptom severity and patient QOL, assessed using the validated Skindex-16 questionnaire. Atopic dermatitis patients receiving the standard therapy (n=771) were enrolled in the current phase IV, multicenter, 12-week, open-label study. The Rajka and Langeland scale (used to rate the severity of atopic dermatitis symptoms) and the Skindex-16 QOL questionnaire were completed at weeks 0 (baseline), 4 and 12. Of 415 patients completing the questionnaire at all time points (per-protocol population), 95.2% were prescribed the antihistamine fexofenadine HCl 60 mg. There were significant improvements in symptoms, emotions and functioning scale scores at weeks 4 and 12 compared with baseline (PSkindex-16, improved over the treatment period (score decreased by >or=1 and >or=2 in 75.2% and 50.9% of patients, respectively). Significant (P<0.005) improvements from baseline in global scores were also observed at weeks 4 and 12, and for week 12 compared with week 4. Severity scores improved significantly (P<0.005) from weeks 0-4 and from weeks 4-12. The standard therapy was generally well tolerated with only mild adverse events reported (0.5%). These data suggest that patients with atopic dermatitis and associated pruritus experience significant improvements in both symptom severity and QOL when receiving standard therapy. PMID:17204095

    Atopic dermatitis (AD) is a commonly occurring chronic skin disease with high heritability. Apart from filaggrin (FLG), the genes influencing atopic dermatitis are largely unknown. We conducted a genome-wide association meta-analysis of 5,606 affected individuals and 20,565 controls from 16......(-8)). We also replicated association with the FLG locus and with two recently identified association signals at 11q13.5 (rs7927894; P = 0.008) and 20q13.33 (rs6010620; P = 0.002). Our results underline the importance of both epidermal barrier function and immune dysregulation in atopic dermatitis...

    The thesis is organized as follows: Chapter 1 describes the theoretical framework of non-leptonic B$0\\atop{s}$ → H+h'- decays, with a simple overview of the CP violation mechanism within the Standard Model and of the most used phenomenological approaches in the evaluation of strong interaction contributions. The chapter contains also a review of the theoretical expectations and the current experimental measurements along with a discussion about the importance of studying such decays. Chapter 2 contains a general description of the Tevatron collider and of the CDF II detector. Chapter 3 is devoted to the description of the data sample used for the measurement and the method used in extracting the signal from the background. Particular attention is dedicated to the on-line trigger selection, which is crucial to collect a sample enriched in B$0\\atop{s}$ → h+h'- decays. Chapter 4 shows how the information from kinematics and particle identification was used to achieve a statistical discrimination amongst modes to extract individual measurements. The available resolutions in mass or in particle identification are separately insufficient for an event-by-event separation of B$0\\atop{s}$ → h+h'- modes. The choice of observables and the technique used to combine them is an important and innovative aspect of the analysis described in this thesis. Chapter 5 is devoted to the accurate determination of the invariant mass lineshape. This is a crucial ingredient for resolving overlapping mass peaks. This chapter details all resolution effects with particular attention at the tails due to the emission of low-energy photons from charged kaons and pions in the final state (FSR). For the first time the effect of FSR has been accurately accounted for in a CDF analysis. Chapter 6 describes how kinematic and PID information, discussed in chap. 4 and chap. 5 were combined in a maximum Likelihood fit

    Interferon-gamma (IFNgamma) gene expression is tightly regulated in early life, and exaggerated negative control of IFNgamma production in CD4(+) T cells has been associated with risk for subsequent development of atopy. Recent studies have demonstrated hypermethylation of CpG sites in the IFNgamma promoter in neonates, a mechanism which in mice leads to strong suppression of IFNgamma gene transcription. In the present study, the methylation status of six CpG sites in the proximal promoter of the human IFNgamma gene was determined by bisulphite sequencing. Cell populations studied were Th1 or Th2 polarized cell lines derived from neonatal and adult CD4(+)/CD45RA(+) T cells, CD4(+) and CD8(+) naive T cells from cord blood of children followed to outcome age 2 for assessment of atopy status, and CD4(+) and CD8(+) naive T cells from 6 yr old and adult atopics and controls. We demonstrate that in vitro differentiation of CD4(+) T cells down the Th1 pathway (but not the Th2 pathway) is accompanied by progressive demethylation of CpG sites in the IFNgamma promoter, which is most marked in neonatal cells. Atopy development by age 2 was not associated with variations in methylation patterns in cord blood T cells. However, IFNgamma promoter methylation was reduced in CD8(+) T cells from atopic children in the age range in which hyperproduction of IFNgamma as recently been identified as a common feature of the atopic phenotype. The findings demonstrate the potency of IFNgamma promoter methylation as a mechanism for control of human IFNgamma gene expression, particularly during early life. Differential regulation of IFNgamma promoter methylation in T cells may be an important contributory factor in atopy development in childhood, and this possibility warrants further detailed investigation.

    Atopic dermatitis (AD) is a chronic, inflammatory skin disease in early childhood. Atopic dermatitis is familial disease, often coexists with other atopic diseases with multiple risk factors associated with atopic eczema. The disease is more frequent in urban areas compared with rural areas. Changes in nutrition and a decrease in infant breast-feeding and respiratory allergies are contributory factors for the condition. A Randomized Controlled Trial (RCT) was carried to compare the efficacy and safety of Tacrolimus ointment with a topical corticosteroid reference therapy. A total 60 patients aged between 2 to 10 years, having atopic dermatitis for at least one year and comply Hanifin-Rajka criteria were selected using random number table and allocated into study and control groups through randomization. Study group was treated with topical Tacrolimus 0.03% twice daily for three weeks, while the control group was treated with 1% Hydrocortisone acetate for the same period. Both groups had a washed out phase for 2 weeks with a follow up period of 6 weeks. Eczema Area and Severity lndex (EASI) was assessed at baseline and three weeks after treatment. Efficacy was evaluated at each visit by six clinical signs of atopic dermatitis through measurement of the affected surface area and the EASI score in each of four body regions. Before intervention, in study group mean EASI score was 11.29 with a SD of 2.14, while in control group it was 11.05 with a SD of 2.46. Difference was statistically insignificant (p>0.05). At the end of the treatment, in study group mean EASI score was 4.86 with a SD of 1.01, while in control group it was 7.97 with a SD of 1.80. Statistically high significant difference was observed between EASI scores of two groups before and after the treatment (pHydrocortisone, median reduction of EASI score was 27.16. Difference was highly significant (p<0.001). It is evidenced that Tacrolimus ointment (0.03%) acts as an effective as well as safe non

    Atopic dermatitis is considered an important risk factor for chronic hand dermatitis, which can be seen in children too. Pimecrolimus cream 1% is approved to treat atopic dermatitis in children aged 2 years or older. In adults, this drug has been used for some clinical indications other than atopic dermatitis, such as chronic hand dermatitis. Here, we describe an adverse drug reaction in a 2-year-old child affected with atopic dermatitis, who was treated with topical pimecrolimus in order to ameliorate her concomitant hand dermatitis. The use of topical pimecrolimus led to a previously undescribed hand pustular dermatosis, being consistent with a form of pustular leukocytoclastic vasculitis, which required the permanent discontinuation of topical pimecrolimus.

    Full Text Available Cílem našeho výzkumu bylo zjistit, jakým způsobem slovinská média referují o sportovních akcích. Zvláště nás zajímalo, zda převládají zprávy o sportovcích a zda existují rozdíly ve způsobu, počtu a stylu článků o sportovcích a sportovkyních. Analyzovali jsme dva deníky a porovnávali rozsah, počet článků a fotografie. Články jsme rozřadili do tří skupin: články o sportovcích, články o sportovkyních a články o obojích současně. Podrobněji jsme sledovali jejich styl. Velkou úlohu rovněž hrají fotografie. Srovnávali jsme proto množství, typ, velikost a statický/dynamický charakter fotografií. Výsledky této studie potvrzují některé z předběžných závěrů o tom, že noviny sportovkyním poskytují méně místa, publikují o nich méně článků a věnují jim menší pozornost. Zkoumáním fotografií jsme došli k závěru, že fotografie sportovců jsou lépe umisťovány a že jsou častěji barevné. Sportovkyně jsou zobrazovány tak, aby vynikal jejich tělesný vzhled a nikoli sportovní role. The aim of our research was to establish how Slovene media report on sporting events. We were especially interested if there is a prevalence of reports about male athletes, and if there are differences in manner, amount and style of reporting between the articles about male and female athletes. We analysed two daily newspapers and compared the size, the number of articles, and the photographs. We have classified the articles into three groups; articles about male athletes, articles about female athletes and articles about both. We took a closer look at the style of writing. The photographs also play an important role. Therefore, we also compared the amount, type, size and static/dynamics of photographs. The results of this study confirm some of the preliminary conclusions that the newspapers offer less space, publish less articles and pay less attention to female athletes. By

    Full Text Available BACKGROUND: Although a number of epidemiological studies, showing incidence and prevalence of atopic dermatitis, were available, scant attention has been paid to the correlation between the parameters of the disease like severity, absolute eosinophil count and IgE level, which has been known to be associated inconsistently. Hence this study was undertaken. METHODS: A total of 102 patients of atopic dermatitis, both children and adults, and 107 age matched controls were studied at the Pediatric Dermatology clinic, Institute of Child Health and department of Dermatology, AMRI-Apollo hospitals, Kolkata. RESULTS: The average age of onset of atopic dermatitis was observed to be 4.55 years. Both the average absolute eosinophil count and IgE levels in patients of atopic dermatitis were significantly higher than that of the controls. Each of these parameters showed significant correlation with severity of the disease and showed a nonhomogeneous distribution reflected by significant association with personal history of bronchial asthma and family history of atopy, when both parents were atopic. CONCLUSIONS: Our study shows that clinical activity of the disease as recorded by the "SCORAD" index can be used as an indicator of the hematological abnormalities as well as to some extent as a prognostic indicator. Family history of atopy correlates with the hematological abnormalities only if both parents are involved and bronchial asthma is the only associated atopic condition which correlates with the parameters of the disease .

    The significance of allergen-specific IgE as marker for severity of atopic dermatitis is controversial. The aim of this study was to determine the frequency of IgE-mediated sensitisation to food and environmental allergens in 132 children and 67 adults with atopic dermatitis, and its correlation to severity of atopic dermatitis (SCORAD). Total IgE was elevated (> 100 kU/l) in 79.7% of adults and 46.8% of children. Sensitisation frequencies to allergens, particularly microbial allergens, were up to 10-fold higher in adults compared to children. Severity of atopic dermatitis correlated with elevated total IgE in adults (r = 0.549, p Malassezia spp.-specific IgE in adults (r = 0.429, p = 0.007). Total IgE is a marker for severe atopic dermatitis in both age groups. Malassezia spp.-specific IgE is an important allergen-specific marker for severity of atopic dermatitis in adults.

    Patients commonly inquire about dietary modifications as a means to prevent or manage skin disease. Answering these questions is often challenging, given the vast and conflicting evidence that exists on this topic. This 2-part continuing medical education article summarizes the evidence to date to enable physicians to answer patients' questions in an evidence-based manner. Part I includes atopic dermatitis, acne, and nonmelanoma skin cancer. The role of dietary supplementation, dietary exclusion, food allergy, maternal diet, and breastfeeding in the development and/or prevention of atopic dermatitis is summarized. The dermatoendocrinologic mechanism for the effects of glycemic index/glycemic load and milk on acne is described, as well as related clinical evidence for dietary modifications. Finally, evidence and recommendations for restriction or supplementation of dietary factors in the prevention of nonmelanoma skin cancer, including fat, vitamins A, C, D, and E, and selenium, are reported.

    The frequency of associated comorbidity and the cost of treatments in patients with atopic dermatitis (AD) followed up in primary care settings are poorly known. We carried out a retrospective cohort study on a longitudinal electronic medical records database of patients consulting a panel of general practitioners in France. All subjects with AD diagnosed during the first year of life were selected and matched with infants without the disease according to sex (1,163 vs. 1,163). Subjects were followed up for 9 years. Associated diseases, drug consumptions and available medical costs were detailed. Comparisons between subjects and controls were carried out. Subjects with AD had more comorbidities than others, especially in respiratory and ophthalmic system organs. The number of prescribed treatments in the field of skin diseases as well as overall medical costs (general practitioner consultations and prescribed drugs) were higher among atopic subjects, but differences were attenuated with age.

    Atopic dermatitis (AD) is a familial and chronic inflammatory pruritic skin disease that affects a large number of children and adults in industrialized countries. It is known that one of the prominent features of AD and chronic pruritus is partially due to the histamine released from mast cell. In this work, hydrogel patches with natural herbal extracts were prepared by 'freezing and thawing', and a gamma irradiation. It showed eminent healing results as a consequence of long-term moisturizing effects and natural herbal extracts on atopic wounds. Besides its non-toxicity and human harmlessness, it can be easily attached to or detached from the skin without any trace and help patients to feel refreshment when attached. Based on this work, the hydrogel patches we made can be potentially used as an alternative remedy for not only pruritus in AD, but other dermatitis.

    Full Text Available Background and Design: Atopic dermatitis shows some different clinical appearances.The main aim of this experimental study is to compare the efficacy of pimecrolimus among these clinical subgoups of atopic dermatitis. Material and Method: A total of 70 patients, 50 male and 20 female, aged between 2-38 years were included in the study. Twenty-two patients (%31.4 were pediatric (2-10 years. Patients were investigated in regard to high levels of total IgE, airway allergy, positive skin prick test and triggering allergens. Patients were classified as: mixed, pure intrinsic and pure extrinsic according to Wüthrich classification. Pimecrolimus 1% cream was applied to the patients twice daily for 6 weeks and patients were evaluated with SCORAD index before and after treatment. Results: FAs a result, 58.6% of the patients (n=41 had a successful therapy with pimecrolimus while 4.3% (n=3 had partially successful. Thirty-five patients achieved full remission. The difference between the SCORADs before and after the treatment was found to be statistically significant (p<0.0001.Conclusion: In this study, efficacy of pimecrolimus was compared to mixed, pure intrinsic and pure extrinsic types of atopic dermatitis. Although pimecrolimus was more effective in the pure intrinsic type, it was not statistically significant (p=0,75. There was also an insignificant difference between the mild and moderate atopic dermatitis for the efficacy of pimecrolimus (p=0,107. In addition, it is concluded in this study that the optimum treatment period with pimecrolimus should be approximately 4 weeks for children and 6 weeks for adults and adolescents.

  9. Genetically programmed differences in epidermal host defense between psoriasis and atopic dermatitis patients.

    Directory of Open Access Journals (Sweden)

    Patrick L J M Zeeuwen

    Full Text Available In the past decades, chronic inflammatory diseases such as psoriasis, atopic dermatitis, asthma, Crohn's disease and celiac disease were generally regarded as immune-mediated conditions involving activated T-cells and proinflammatory cytokines produced by these cells. This paradigm has recently been challenged by the finding that mutations and polymorphisms in epithelium-expressed genes involved in physical barrier function or innate immunity, are risk factors of these conditions. We used a functional genomics approach to analyze cultured keratinocytes from patients with psoriasis or atopic dermatitis and healthy controls. First passage primary cells derived from non-lesional skin were stimulated with pro-inflammatory cytokines, and expression of a panel of 55 genes associated with epidermal differentiation and cutaneous inflammation was measured by quantitative PCR. A subset of these genes was analyzed at the protein level. Using cluster analysis and multivariate analysis of variance we identified groups of genes that were differentially expressed, and could, depending on the stimulus, provide a disease-specific gene expression signature. We found particularly large differences in expression levels of innate immunity genes between keratinocytes from psoriasis patients and atopic dermatitis patients. Our findings indicate that cell-autonomous differences exist between cultured keratinocytes of psoriasis and atopic dermatitis patients, which we interpret to be genetically determined. We hypothesize that polymorphisms of innate immunity genes both with signaling and effector functions are coadapted, each with balancing advantages and disadvantages. In the case of psoriasis, high expression levels of antimicrobial proteins genes putatively confer increased protection against microbial infection, but the biological cost could be a beneficial system gone awry, leading to overt inflammatory disease.

    2001-09-20

    Dogs and human beings with atopic dermatitis (AD) frequently exhibit concurrent skin infections with Staphylococcus sp. bacteria or Malassezia yeast, and treatment of such infections is an important facet of managing these patients. Staphylococci appear to colonize atopic skin readily, and bacterial products on the skin could augment cutaneous inflammation via immediate hypersensitivity responses to the bacteria, by superantigen-mediated lymphocyte activation, or other non-specific mechanisms. Similarly, skin colonization by Malassezia yeast could contribute to clinical signs of AD; yeast components could induce inflammation via non-specific mechanisms, such as alteration in mediator release, or via antigen-specific hypersensitivity reactions. Clinical and experimental evidence exists that secondary microbial infections can both initiate and perpetuate episodes of AD in dogs and humans, and could even participate in promotion of pro-allergic immunologic responses. Mechanistic details of these complex interactions are under extensive investigation in human beings; only a few observations have been extended to include dog with AD. PMID:11553386

    Full Text Available Health political background: In developed countries 2.5% of the population - mainly children - are affected by atopic dermatitis. During the past few years its prevalence amongst school children has risen decisively and now lies between 8% to 16%. It is the most frequent chronic skin disease amongst school-aged children. Scientific background: Current methods of treating atopic dermatitis among children focus on containing and preventing the illness’s further progression. Preventing dry skin, relieving symptoms (such as pruritis and inflammation of the skin and identifying and avoiding provocating factors are elementary goals of treatment. Successful treatment can substantially increase the children’s quality of life. Possible therapies of children affected by atopic dermatitis include both topically and systemically applied pharmaceuticals. During the past ten years the use of corticosteroids has been the standard topical anti-inflammatory therapy in case of aggravating inflammations. In 2002 a new group of pharmaceutical substances (topical calcineurin inhibitors tacrolimus and pimecrolimus was authorised in Germany for topical anti-inflammatory treatment of patients. Because of its high prevalence atopic dermatitis represents a major expense factor to the German health care system. In 1999 the costs of the treatment of atopic dermatitis with corticosteroids in Germany amounted to 230 million Euro. If other direct costs for the treatment are included, for example hospitalisation or doctor appointments, the total costs amount to 3.57 billion Euro. Research question: How effective and efficient are topical anti-inflammatory treatments of children with atopic dermatitis? Methods: A systematic literature search was performed in 35 international databases which yielded 1335 articles. Following a two-part selection process according to predefined criteria 24 publications were included in the assessment. Results: Of 19 randomised controlled

    Angiogenesis is closely linked to and precedes eosinophilic infiltration in asthma. Eosinophils are recruited into the airway by chemoattractant eotaxins, which are expressed by endothelial cells, smooth muscles cells, epithelial cells, and hematopoietic cells. We hypothesized that bone marrow-derived proangiogenic progenitor cells that contain eotaxins contribute to the initiation of angiogenesis and inflammation in asthma. Whole-lung allergen challenge of atopic asthma patients revealed vascular activation occurs within hours of challenge and before airway inflammation. The eotaxin receptor CCR3 was expressed at high levels on submucosal endothelial cells in patients and a murine model of asthma. Ex vivo exposure of murine endothelial cells to eotaxins induced migration and angiogenesis. In mechanistic studies, wild-type mice transplanted with eotaxin-1/2-deficient bone marrow had markedly less angiogenesis and inflammation in an atopic asthma model, whereas adoptive transfer of proangiogenic progenitor cells from wild-type mice in an atopic asthma model into the eotaxin-1/2-deficient mice led to angiogenesis and airway inflammation. The findings indicate that Th2-promoting hematopoietic progenitor cells are rapidly recruited to the lung upon allergen exposure and release eotaxins that coordinately activate endothelial cells, angiogenesis, and airway inflammation.

    Atopic dermatitis (AD) is a chronic and disabling condition that has a major impact on financial and social resources of the individual and the community. Its incidence is increasing dramatically, and no cure is available. Pharmacological treatment is only partially effective. The evidence that diet plays a role in children with atopic dermatitis is now irrefutable. Prophylactic measures can prevent or limit the development of AD, and partially restricted diets can modify the disease's course or severity. This study reports the reactions to various foods as perceived by parents of 112 children affected by AD. It demonstrates that many foods exacerbate AD and that reactions are caused by two distinct groups of food. The commonest triggers of cutaneous symptoms are tomatoes, oranges, sweets, pineapple, chocolate, and softdrinks preserved with sulfur dioxide. These foods result in symptoms in 30% to 49% of the children. The traditional IgE reaction type foods, namely egg, fish, milk, and peanut, resulted in reactions in 14% to 25% of the children, and with many non-cutaneous symptoms. The study further shows that allergen avoidance measures are not practiced in our community, and that sound advice is not often proffered. Practical advice on prophylactic dietary preventative measures and dietary management of children with atopic dermatitis is presented. PMID:7806078

FDK primary cultures (atopic dermatitis, n = 11; non-atopic controls, n = 7 before and after interferon gamma (IFN-γ treatment were used for microarray analysis and quantitative RT-PCR. Comparison of FDKs from atopic and non-atopic donors indicated that the former showed activated pathways with innate immunity and decreased pathways of cell growth, as indicated by increased NLRP2 expression and decreased DKK1 expression, respectively. Treatment with IFN-γ induced the enhanced expression of IL32, IL1B, IL8, and CXCL1 in the cells from atopic donors compared to that in cells from non-atopic donors at 24 h after treatment. IL1B expression in FDKs after IFN-γ treatment correlated with IL32 expression. We hypothesized that overexpression of IL32 in hair follicle keratinocytes of patients with atopic dermatitis would lead to the excessive production of pro-IL1β and that the activation of IL1β from pro-IL1β by inflammasome complex, in which NLRP2 protein might be involved, would be augmented. This is the first report to show enhanced induction of cytokine/chemokine genes by IFN-γ in atopic dermatitis using cultured FDKs.

    Emotional factors and a recurrent psychosomatic environment, have been implicated in the evolution of atopic dermatitis. These, in turn, affect the disease. This study was under taken to evaluate the functioning of families with a child that has atopic dermatitis without skin symptoms and the parents' perceptions of their child's disease.Semi-quantitative and cross-sectional study in which questionnaires were applied: one to study family functioning (Espejel et al. scale) and the second to determine aspects of parental perception of their child's atopic dermatitis. Pearson's correlation was used to analyze the correlation between the categories of the Family Function Scale.The most affected categories of family functioning were authority, handling of disruptive conduct, communication, and negative affect. The most significant positive correlations between the categories of family functioning were: authority and support, r=0.867, pparents, 66.4% thought that the pharmacotherapy used for their child's atopic dermatitis was not effective, and 33.3% of parents stated that the disease had affected their child's daily activities.In families of children with atopic dermatitis, various family environment factors facilitate the recurrence of symptoms even when no cutaneous lesions have been found on the child. The identification and use of family resources to face this disease are aspects that should be taken into consideration during the psychotherapeutic management of these families, putting emphasis on the most affected functional categories of these families in a strategy that should be implanted in a multi-disciplinary context.

    In industrialized countries atopic diseases have been reported to be less likely in children and adolescents with a migrant background compared to non-migrants. This paper aimed at both examining and comparing prevalence of asthma, allergic rhinoconjunctivitis and atopic dermatitis and allergic sensitization to specific IgE antibodies in children and adolescents with and without a migrant background. Using data of the population-based German Health Interview and Examination Survey for children and adolescents (KiGGS;n = 17,450; 0-17 years), lifetime and 12-month prevalence of atopic diseases and point prevalence of 20 common allergic sensitizations were investigated among migrants compared to non-migrants. Multiple regression models were used to estimate the association of atopic disease and allergic sensitization with migrant background. In multivariate analyses with substantial adjustment we found atopic dermatitis about one-third less often (OR 0.73, 0.57-0.93) in participants with a two-sided migrant background. Statistically significant associations between allergic sensitizations and a two-sided migrant background remained for birch (OR 0.73, 0.58-0.90), soybean (OR 0.72, 0.54-0.96), peanut (OR 0.69, 0.53-0.90), rice (OR 0.64, 0.48-0.87), potato (OR 0.64, 0.48-0.85), and horse dander (OR 0.58, 0.40-0.85). Environmental factors and living conditions might be responsible for the observed differences. PMID:26927147

    Full Text Available Context: Frictional lichenoid dermatitis. Background: Frictional lichenoid dermatitis (FLE is an entity that is probably under diagnosed and has been variably associated with either friction and/or atopy with a distinctive seasonal variation. Aims and Objectives : To study correlation of FLE with UV index and to assess its association with atopic dermatitis. Materials and Methods: A cross sectional analysis of children with FLE was done, over a period of 6 years in two tertiary hospitals. A detailed history and examination was done to assess the features of atopic dermatitis. The number of cases seen per month was compared with the mean monthly UV index. Two-tailed significance tests using Pearson′s coefficient of correlation and T-test were used to interpret the data. (P < 0.05. Results: One hundred seventy-four patients were studied using the UKC criterion 17.2% of the patients had AD while xerosis (40.3% was the predominant cutaneous finding. The number of patients seen in summer was more than in winter (P < 0.05 but there was no statistical difference between the cases in winter and spring. There was a significant correlation of the number of cases per month with UV index (P = 0.019. Almost 42% of patients gave a history of recurrence. Conclusions : FLE is probably not associated with atopic dermatitis and is likely to be related to the ambient UV index though a larger cohort with meticulous follow up may be needed to draw a final conclusion. Statistical Analysis Used: The Pearson′s coefficient of correlation was used for comparing the cases per month with the UV index. The tests of hypothesis used included the paired T-tests. F-test of variance, Welch test, Wilcoxon rank sum test and the Kolmogorov-Smirnov Test. P < 0.05 was considered significant.

    Directory of Open Access Journals (Sweden)

    N. V. Kolesnikova

    2016-01-01

    Full Text Available Increased incidence of allergic diseases worldwide reflects some mangles of the existing pharmacotherapy concept which ignores some etiopathogenetic aspects of clinical atopy. Meanwhile, understanding cellular and molecular mechanisms of allergy may create prerequisites for development of new therapeutic areas, in order to effectively influence pathogenesis points of allergic inflammation and, thus, leading to therapeutic success. The review article concerns an antagonism between the two populations of T-helper cells (Th1 and Th2 carried out mainly by the action of IFNγ produced by activated Th1, and IL-4 secreted by activated Th2 which is at the heart of modern concept on the regulation of adaptive immunity. The prospects of immunotherapy of allergic diseases based on the polarization of the immune response are discussed, i.e., an activation of Th1 responses and Th2 suppression. This functional polarization can be mediated by the innate immune receptor agonist, i.e., synthetic and natural minimally-sized biologically active fragments (MBAF with pathogen-associated molecular patterns. In this respect, a very promising drug registered in Russia is based on the synthetic MBAF, glucosaminylmuramyldipeptide (GMDP, The liсopid immunomodulator. This is due to the fact that GMDP, being an active substance of Liсopid, is a highly specific ligand for the NOD2 receptor of innate immunity factors; it may cause activation of the NF-kB transcription factor, and production of multiple immunoregulatory cytokines. Clinical and immunological efficacy of Licopid application in conventional therapy of atopic allergic diseases (asthma, atopic dermatitis, atopic variant of acute obstructive bronchitis is presented as an overview of pre-clinical and clinical trials.

  12. Di-(2-ethylhexyl) phthalate affects immune cells from atopic prone mice in vitro

    International Nuclear Information System (INIS)

    Phthalate esters as plasticizers have been widespread in the environment and may be associated with development of allergic diseases such as asthma and atopic dermatitis. However, the underlying mechanisms have not been fully elucidated. The present study investigated the effects of di-(2-ethylhexyl) phthalate (DEHP) on immune cells from atopic prone NC/Nga mice in vitro. Bone marrow-derived dendritic cells (BMDC) as a professional antigen-presenting cell and splenocytes as mixture of immune cells were used. BMDC were differentiated by culture with granulocyte macrophage-colony stimulating factor (GM-CSF) in the presence of DEHP (0.1-10 μM) for 6 days. In another experiments, BMDC were differentiated by culture with GM-CSF for 8 days then these BMDC were exposed to DEHP (0.1-100 μM) for 24 h. Splenocytes were exposed to DEHP for 24 h (0.1-100 μM) or 72 h (0.1-1000 nM). After the culture, the phenotypic markers and the function of BMDC and splenocytes were evaluated. BMDC differentiated in the presence of DEHP showed enhancement in the expression of MHC class II, CD86, CD11c and DEC205, and in their antigen-presenting activity. On the other hand, the function of the differentiated BMDC was not activated by DEHP although DEHP partly enhanced their expression of DEC205. DEHP-exposed splenocytes showed increases in their TCR and CD3 expression, interleukin-4 production, and antigen-stimulated proliferation. These results demonstrate that DEHP enhances BMDC differentiation but not activation and also enhances Th2 response in splenocytes from atopic prone mice. The enhancement might contribute to the aggravating effect of DEHP on allergic disorders.

    Modifications were designed for the B-737-100 Research Aircraft autobrake system hardware of the Advanced Transport Operating Systems (ATOPS) Program at Langley Research Center. These modifications will allow the on-board flight control computer to control the aircraft deceleration after landing to a continuously variable level for the purpose of executing automatic high speed turn-offs from the runway. A bread board version of the proposed modifications was built and tested in simulated stopping conditions. Test results, for various aircraft weights, turnoff speed, winds, and runway conditions show that the turnoff speeds are achieved generally with errors less than 1 ft/sec.

    Thymic stromal lymphopoietin (TSLP) potently induces deregulation of Th2 responses, a hallmark feature of allergic inflammatory diseases such as asthma, atopic dermatitis, and allergic rhinitis. However, direct downstream in vivo mediators in the TSLP-induced atopic immune cascade have not been identified. In our current study, we have shown that OX40 ligand (OX40L) is a critical in vivo mediator of TSLP-mediated Th2 responses. Treating mice with OX40L-blocking antibodies substantially inhibited immune responses induced by TSLP in the lung and skin, including Th2 inflammatory cell infiltration, cytokine secretion, and IgE production. OX40L-blocking antibodies also inhibited antigen-driven Th2 inflammation in mouse and nonhuman primate models of asthma. This treatment resulted in both blockade of the OX40-OX40L receptor-ligand interaction and depletion of OX40L-positive cells. The use of a blocking, OX40L-specific mAb thus presents a promising strategy for the treatment of allergic diseases associated with pathologic Th2 immune responses. PMID:18060034

    Full Text Available Two cases of women in their thirties with past histories of atopic dermatitis and allergic rhinitis developed a low grade fever, followed by a butterfly-shaped erythema, swelling of their fingers, and polyarthralgia. Despite such symptoms that overlap with those of systemic lupus erythematosus (SLE, the diagnostic criteria for SLE were not fulfilled. Due to positive results for human parvovirus B19 (HPV-B19 IgM antibodies in the serum, diagnoses of HPV-B19 infection were made in both cases. Although acetaminophen failed to improve their deteriorating symptoms, a nonsteroidal anti-inflammatory drug (NSAID, loxoprofen, completely removed the symptoms immediately after the administration. In those cases, since the patients were predisposed to atopic disorders, an increased immunological response based on the lymphocyte hypersensitivity was likely to be involved in the pathogenesis. The immunomodulatory property of NSAID was thought to repress such lymphocyte activity and thus provided a rapid and sustained remission of the disease.

    Atopic dermatitis (AD) affects 10% to 20% of children worldwide. Its severity may be inversely correlated with 25-hydroxyvitamin D (25OHD) levels. Although low levels of vitamin D (VD) can cause rickets in infants, VD deficiency rickets is an unusual presentation in teenagers. We report the case of a 14-year-old girl with severe AD and fish allergy since early childhood. She lived at high latitude (with less sun exposure) and, because of her atopic disorders, avoided sunlight and fish. Laboratory studies showed elevated alkaline phosphatase and parathyroid hormone levels and low serum calcium; her serum 25OHD level was rickets due to VD deficiency. Treatment with VD increased her 25OHD level to 44 nmol/L, with normalization of alkaline phosphatase, parathyroid hormone, and calcium. Moreover, we observed a dramatic improvement in her AD severity with VD treatment. This case demonstrates the complex interaction between VD deficiency, AD, and food allergy. We advise a high index of suspicion of VD deficiency rickets in children of all ages with AD, particularly during accelerated growth periods and in the presence of other risk factors such as darker skin, living at high latitude, sun avoidance, and low intake of VD-rich foods. The concomitant improvement in bone-related parameters and AD severity may reflect a double benefit of VD treatment, a possibility that warrants research on VD as potential treatment for AD.

    Historically, German chamomile (GC) oil has been used for treatment of skin disorders. BALB/c mice were sensitized twice a week with 100 microL of 1% 2,4-dinitrochlorobenzene (DNCB) and challenged twice the following week with 100 microL of 0.2% DNCB for atopic dermatitis induction. Thereafter, 3% GC oil was applied daily (70 microL, 6 times week) on the dorsal skin for 4 weeks. Saline or jojoba oil was used for the control mice. Blood was collected after second DNCB challenge, and at 2 and 4 weeks after initiating oil application. Serum IgE levels were significantly lowered in the GC oil application group at the end of the 4-week application period. The GC oil application for 4 weeks resulted in reduction in serum IgG1 level compared with that after 2-week application. The GC oil application group showed a significantly lower serum histamine level than the control group 2 weeks after oil application. Scratching frequency of the GC oil application group was significantly lower than either control groups. This study is to demonstrate GC oil's immunoregulatory potential for alleviating atopic dermatitis through influencing of Th2 cell activation.

Both poor water solubility and drug permeability have hindered the percutaneous absorption of silymarin. Formulation of silymarin into pluronic-lecithin organogel (PLO basis for topical skin delivery is the main aim of this work. Six different PLO formulations were prepared containing various pluronic to lecithin ratios using two cosolvent systems of ethyl alcohol and dimethyl sulfoxide. Formulation 2 (20% pluronic and 3% lecithin was found to be the optimal base for topical delivery of silymarin as it showed optimum pH, viscosity, drug content, and satisfactory in vitro silymarin permeation. The silymarin PLO formulation significantly relieved inflammatory symptoms of AD such as redness, swelling, and inflammation. These findings warrant the ability for application of these novel silymarin PLO formulations as a novel treatment for AD.

    Atopic dermatitis (AD) and acne vulgaris are among the most-prevalent skin diseases in children. Both have been well documented in the literature to have significant negative effects on quality of life. Herein, we discuss the results of a comprehensive literature review aimed at assessing the impact of acne and AD on self-esteem and identity. We highlight clinical tools for their assessment and offer coping strategies for patients and families. Multiple factors including relationships with parents and classmates, sports participation, and the sex of the patient contribute to the development of self-esteem and identity in individuals with AD and acne. Atopic dermatitis was found to have significant behavioral effects on children, ultimately resulting in a lack of opportunity to develop proper coping. AD had a more-prominent role in identity formation and gender roles in girls. Acne vulgaris was found to have a more direct effect on self-esteem, self-confidence and identity, especially in girls. The Cutaneous Body Image Scale is reviewed and offered as an easy and reliable tool to evaluate a patient's mental perception of the appearance of their skin. Coping strategies that may be offered to patients and families include empowerment and cognitive adaptation. PMID:27001316

    Full Text Available This study was conducted to evaluate the role of swimming on mechanic of lung in healthy individual and patients with asthma. A total 76 girls who took part in the course of regular swimming session three day per week for eight weeks enrolled in this study. All of them completed ISAAC written questionnaire and individual who was suspected of asthma or other atopic diseases was referred to allergist for more evaluation. Peak expiratory flow rate was recorded for participants at beginning, one hour after swimming and two months later. According to ISAAC questionnaire 35.4% had asthma or other atopic diseases. Increase in PEFR more than 20% of personal best was seen in 21.9% after one hour swimming and in 27.6% after two months. Increase in PEFR was significant in healthy individual and asthmatic patients and obese but was not significant in patients with allergic rhinitis or eczema. This study suggests swimming in indoor pool is useful for patients with asthma in spite of potential toxic role of chlorine in exacerbation of asthma symptoms and lung mechanics.

    Atopic asthma is characterized by the production of allergen-specific IgE and IgG{sub 4} antibody and airway hyperreactivity caused by interactions between the immune system and inhaled allergens. Recent studies suggest that the production of IgE and IgG{sub 4} antibody important in atopic disease requires help from Th2 lymphocytes, while Th1 lymphocytes support the production of immune responses that would not cause asthma. The evaluation of cells from the lungs of asthmatics indicated that they have elevated Th2 immune responses. However, no study has compared the immune responses that develop in asthmatics and normals (people without asthma) after their lungs are exposed to a neoantigen. The purpose of this study was to determine if Th2 immunity would be produced to a neoantigen, keyhole limpet hemocyanin (KLH), deposited in the lungs of asthmatics, while Th1 immunity would be produced to KLH deposited in the lungs of nonasthmatics. Because the production of IgG{sub 4} requires Th2 immune help, the higher level of anti-KLH IgG{sub 4} in the serum of asthmatics suggests that a Th2 immune response was produced to a neoantigen deposited in their lungs.

    Full Text Available The symptoms of atopic dermatitis (AD are often aggravated by stress, and AD can also lead to psychological stress due to social isolation and discrimination. The salivary cortisol level reflects psychological stress, and it is a good index to assess chronic stress. In this study, we measured the salivary cortisol levels in patients with AD (. AD patients were also evaluated for general disease severity using the Scoring Atopic Dermatitis (SCORAD index. The serum levels of TARC, total IgE, and lactate dehydrogenase (LDH and peripheral blood eosinophil counts were measured by laboratory tests. The Skindex-16 was used as a skin disease-specific, quality of life measure, instrument. The results showed that the saliva cortisol level was significantly higher in AD patients compared to healthy subjects ( while the serum TARC and LDH levels were positively correlated with the SCORAD index. However, no statistically significant correlations were observed between the salivary cortisol level and Skindex-16. These results suggest that the saliva cortisol level is therefore a useful biomarker to evaluate the stress in AD patients.

    Full Text Available The prevalence of atopic dermatitis has significantly increased in developed countries during the past several decades. Surveys performed in Hungary also show a growing number of atopic dermatitis (AD cases, although, a carefully designed case-controlled studies have not been performed. Therefore, we investigated the prevalence of AD in individuals under 19 years of age within the agricultural area of East-Hungary. Combined data obtained with Schultz-Larsen questionnaire on 1158 children were analyzed, and 25% of the index persons were examined by dermatologist. The mean prevalence of AD determined by questionnaires appeared to be 17.5% in the entire study population. Result of dermatological examination verified the validity and sensitivity of the questionnaire. A negative correlation was found between the severity of the disease and the length of breast feeding period. (Spearman's correlation coefficient = − 0.2247, p = 0.034. The prevalence of AD in an East-Hungarian agricultural area is nearly as high as that reported for populations residing in industrially developed countries, with a higher prevalence during childhood. Data suggest that premature abruption of breast feeding maybe one of the major factors among other environmental factors that is contributing to the development of AD.

    A 34-year-old Japanese woman presented with a 2-year history of generalised bone pain, muscle weakness and gait disturbance. The patient had been following a restricted diet (without fish or dairy products) and avoiding ultraviolet exposure for 8 years to manage her worsening atopic dermatitis. Physical examination revealed generalised bone tenderness and bilateral symmetric proximal muscle weakness. Vitamin D-deficient osteomalacia was diagnosed based on the laboratory examination findings, which indicated high serum alkaline phosphatase, high intact parathyroid hormone, and low 25-hydroxyvitamin D levels. Her symptoms improved after oral active vitamin D and calcium administration. To the best our knowledge, this case is the first report of vitamin D-deficient osteomalacia in an adult patient due to excessive dietary restriction for managing atopic dermatitis. We emphasise the importance of increasing awareness of vitamin D deficiency as a risk factor for the development of osteomalacia, and caution against excessive avoidance of sun exposure and dietary restriction.

  3. Allergies and Asthma: Do Atopic Disorders Result from Inadequate Immune Homeostasis arising from Infant Gut Dysbiosis?

    Johnson, Christine C; Ownby, Dennis R

    2016-04-01

    Our global hypothesis is that atopic conditions and asthma develop because an individual's immune system is not able to appropriately resolve inflammation resulting from allergen exposures. We propose that the failure to appropriately down-regulate inflammation and produce a toleragenic state results primarily from less robust immune homeostatic processes rather than from a tendency to over-respond to allergenic stimuli. An individual with lower immune homeostatic capacity is unable to rapidly and completely terminate, on average over time, immune responses to innocuous allergens, increasing risk of allergic disease. A lack of robust homeostasis also increases the risk of other inflammatory conditions, such as prolonged respiratory viral infections and obesity, leading to the common co-occurrence of these conditions. Further, we posit that the development of vigorous immune homeostatic mechanisms is an evolutionary adaptation strongly influenced by both 1) exposure to a diverse maternal microbiota through the prenatal period, labor and delivery, and, 2) an orderly assemblage process of the infant's gut microbiota ecosystem shaped by breastfeeding and early exposure to a wide variety of ingested foods and environmental microbes. This early succession of microbial communities together with early allergen exposures orchestrate the development of an immune system with a robust ability to optimally control inflammatory responses and a lowered risk for atopic disorders.

    Full Text Available Objective. To determine efficacy and safety of Carbopol 974P in the treatment of severe to moderate keratoconjunctivitis sicca (KCS in patients with primary Sjögren’s syndrome (SS not responding to standard treatment with artificial tears. Methods. 60 patients (57 F, 3 M, mean age 52.5±12.0, mean disease duration 12.2±7.1 yrs affected with primary SS diagnosed according to the European Community Study Group criteria were studied. Foregoing medications for SS and artificial tears for KCS have not been changed within 3 and 2 months respectively prior to the study onset. In all cases Carbopol 974P was added because symptoms of KCS were not adequately controlled with traditional lubricants. Schirmer I test, B.U.T. (break up time, rose Bengal-stain, clinical ophthalmological examination (i.e. fluorescein staining, keratis, corneal infiltrates and ulcers and a questionnaire for dry eye symptoms (range 0-30 were performed at entry (T0 and after 2 (T1 and 12 (T2 weeks. Assessment of global efficacy was obtained by VAS 0-100 at T2 either by patients and by the ophthalmologist. Results. Lachrymal tests significantly improved after 2 and, even more, after 12 weeks. Clinical ophthalmologic picture also ameliorated: a remarkable reduction of fluorescein positive lesions was demonstrated from 71.6% of the cases at T0 to 38.3% at T2. Total score of symptoms (T0: 16.1±7.3 dropped to 11.9±6.6 (T1 (p=0.000 and then to 6.7±5.3 (T2 (p=0.000. Global efficacy expressed by patients and physician was 74.8±15.9 and 76.6±13.0, respectively. No adverse events (blurred vision, allergy were reported throughout the study. Conclusions. Our study seems to demonstrate that addition of Carbopol 974P to the traditional therapeutic armamentarium for moderate to severe KCS is useful and well accepted in patients with primary SS in which management of ocular symptoms is unsatisfactory.

    Atopic dermatitis (AD) is a multifactorial inflammatory skin disease that affects both children and adults in an increasing manner. The treatment of AD often reduces subjective skin parameters, such as itching, dryness, and tension, but the inflammation cannot be cured. Laser scanning microscopy was used to investigate the skin surface, epidermal, and dermal characteristics of dry and atopic skin before and after treatment with an ointment rich in hyperforin, which is known for its anti-inflammatory effects. The results were compared to subjective parameters and transepidermal water loss, stratum corneum moisture, and stratum corneum lipids. Using biophysical methods, in particular laser scanning microscopy, it was found that atopic skin has distinct features compared to healthy skin. Treatment with a hyperforin-rich ointment resulted in an improvement of the stratum corneum moisture, skin surface dryness, skin lipids, and the subjective skin parameters, indicating that the barrier is stabilized and improved by the ointment. But in contrast to the improved skin surface, the inflammation in the deeper epidermis/dermis often continues to exist. This could be clearly shown by the reflectance confocal microscopy (RCM) measurements. Therefore, RCM measurements could be used to investigate the progress in treatment of atopic dermatitis.

    Atopic dermatitis is a common inflammatory skin disease caused by interaction of genetic and environmental factors. On the basis of data from a genome-wide association study (GWAS) and a validation study comprising a total of 3,328 subjects with atopic dermatitis and 14,992 controls in the Japanese population, we report here 8 new susceptibility loci: IL1RL1-IL18R1-IL18RAP (P(combined) = 8.36 × 10(-18)), the major histocompatibility complex (MHC) region (P = 8.38 × 10(-20)), OR10A3-NLRP10 (P = 1.54 × 10(-22)), GLB1 (P = 2.77 × 10(-16)), CCDC80 (P = 1.56 × 10(-19)), CARD11 (P = 7.83 × 10(-9)), ZNF365 (P = 5.85 × 10(-20)) and CYP24A1-PFDN4 (P = 1.65 × 10(-8)). We also replicated the associations of the FLG, C11orf30, TMEM232-SLC25A46, TNFRSF6B-ZGPAT, OVOL1, ACTL9 and KIF3A-IL13 loci that were previously reported in GWAS of European and Chinese individuals and a meta-analysis of GWAS for atopic dermatitis. These findings advance the understanding of the genetic basis of atopic dermatitis.

    The so-called 'adjuvant' measures are an important part of atopic dermatitis (AD) consultations. The practitioner is the 'expert' in the patients' eyes in prescribing, proposing, counselling and replying to the questions concerning moisturizers, thermal spring water cures, the resort to alternative medical, and vaccinations. Moisturizers are aimed at rapidly restoring water in the epidermis, decreasing the sensitivity to irritants and improving the patients' comfort. The available products are usually composed of water, occlusive agents, humidifiers, varyingly combined with tensioactive agents, preservatives and perfumes... Their short term efficacy has been demonstrated, but no study has shown superiority of one product over another. The recommended treatment is 1 to 2 daily applications of a cream or lotion, selected among the products having demonstrated their efficacy, contained the least amount of irritant or sensitizers, the presentation and cost of which is acceptable to the patient. There are no arguments to recommend moisturizers in the absence of xerosis, nor for prolonged periods of clinical remission. Spring water thermal cures. In France there are many cure centres and the spring waters used are distinguished by their clinical or physical features. Although there are no studies that clearly establish their efficacy in AD, the craze and satisfaction of many patients for spring water thermal cures must be taken into consideration, as well as the educational dimension, in the hopes that a consensus will be reached and that regular assessments be made. Alternative medical practices, such as homeopathy or acupuncture, represent a therapeutic alternative chosen by more than one third of patients with AD. However, no study has sufficiently demonstrated the interest of these alternatives and they cannot therefore be integrated in the validated arsenal of treatments. Used in various oriental countries, Chinese herbs have been the subject of controlled studies

    Full Text Available Emotional factors and a recurrent psychosomatic environment, have been implicated in the evolution of atopic dermatitis. These, in turn, affect the disease.This study was under taken to evaluate the functioning of families with a child that has atopic dermatitis without skin symptoms and the parents’ perceptions of their child’s disease.Semi-quantitative and cross-sectional study in which questionnaires were applied: one to study family functioning (Espejel et al. scale and the second to determine aspects of parental perception of their child’s atopic dermatitis. Pearson’s correlation was used to analyze the correlation between the categories of the Family Function Scale.The most affected categories of family functioning were authority, handling of disruptive conduct, communication, and negative affect. The most significant positive correlations between the categories of family functioning were: authority and support, r=0.867, p<.001; disruptive conduct and communication, r=0.798, p<.001; and support and communication, r=0.731, p<.001. Of the parents, 66.4% thought that the pharmacotherapy used for their child’s atopic dermatitis was not effective, and 33.3% of parents stated that the disease had affected their child’s daily activities.In families of children with atopic dermatitis, various family environment factors facilitate the recurrence of symptoms even when no cutaneous lesions have been found on the child. The identification and use of family resources to face this disease are aspects that should be taken into consideration during the psychotherapeutic management of these families, putting emphasis on the most affected functional categories of these families in a strategy that should be implanted in a multi-disciplinary context.

Moreover, the effect of P. ovale on atopic dermatitis according to different geographic conditions was also determined. Methods: Thirty-one patients with atopic dermatitis, who were admitted to İstanbul Medical Faculty Dermatology Clinic, were enrolled. Skin prick tests were performed for P. ovale and house dust mites (D. pteronyssinus ve D. farinea Results: Ten patients (32.3% showed positive reaction to D. pteronyssinus, nine patients (29% to D. farinea, and nine patients (29% to P. ovale. Head and neck involvement was observed in 22 patients. Head and neck involvement was mostly seen in the patients in the first two decades of life (48%. Eczema was significantly more severe in the patients with head and neck involvement compared to that in those without (p500 IU/mL were significantly higher in the head and neck involvement group (p<0.05. Conclusion: Although the effect of P. ovale on atopic dermatitis in head and neck involvement could not be demonstrated in the present study, it should not be ignored. The results of skin prick test for P. ovale might change according to age and disease severity. Geographical variations of Malassezia species distribution should be kept in mind while evaluating test results. Moreover, it should be remembered that inhalan allergens are also triggering factor in some patients with atopic dermatitis with head and neck involvement.

    Full Text Available Canine atopic dermatitis (CAD is a common dermatosis, defined as a genetic-related disease which predisposes to skin inflammation and pruritus, associated to a IgE-specific response in most of cases. Clinical diagnosis may be later complemented by skin allergy and/or serological tests. The aim of these tests is to identify possible allergens in order to enable the clinicians to select candidate antigens for allergen specific immunotherapy. In the present study 58 CAD positive animals were tested. All were submitted to the intradermal test (IDT and screened for the presence of antibodies against different antigens using ELISA. The obtained results show a high prevalence of sensitization among the tested dogs to house dust mites and to pollen ofC. dactylon. With this work it was possible to identify the main allergens involved in immunological response of dogs with CAD living in central area of Rio Grande do Sul.

    Canine atopic dermatitis (cAD) is a major teaching point as its diagnosis and treatment are difficult. During 11 weeks, 140 dogs and students (third, fourth, and fifth years) were recruited and paired. One of the four lists of diagnostic criteria was randomly attributed to each student. Concordance results, calculated with Cohen's kappa, ranged from slight (κ=0.07) to moderate (κ=0.53). Favrot's diagnostic criteria received the best results. It has been observed that results are improved with clinical experience. We observed that students often forgot that Favrot's criteria apply only to pruritic dogs and that the fulfillment of the criteria allows only a suspicion, not a diagnosis, of cAD. Primary pruritus and corticosteroid-responsive pruritus were often misunderstood. PMID:25588943

    incidence of AD in 1993 and 1998. Further, we studied the severity and management of AD among children. Two samples of children born in Denmark were drawn from the Danish Medical Birth Register. In the 1993 and 1998 studies a mailed questionnaire with identical questions concerning AD was sent out....... In the 1998 follow-up study the questionnaire included a severity score and questions concerning management of AD. In the 1993 study the cumulative incidence of AD at age 7 was 18.9% and in 1998 it was 19.6%. There was no difference in the age-adjusted AD incidence in the 5-year observation period......An increase in the prevalence of atopic dermatitis (AD) has been reported since the 1960s. The increase could be due to many factors including a genuine increase of incidence or duration of AD. We decided to study if the increasing trend persisted during the 1990s by comparing the cumulative...

    Full Text Available Abstract Background Atopic dermatitis (AD is believed to result from complex interactions between genetic and environmental factors. A main feature of AD as well as other allergic disorders is serum and tissue eosinophilia. Human eosinophils contain high amounts of cationic granule proteins, including eosinophil cationic protein (ECP, eosinophil-derived neurotoxin (EDN, eosinophil peroxidase (EPO and major basic protein (MBP. Recently, variation in genes encoding eosinophil granule proteins has been suggested to play a role in the pathogenesis of allergic disorders. We therefore genotyped selected single nucleotide polymorphisms within the ECP, EDN, EPO and MBP genes in a cohort of 361 German AD patients and 325 healthy controls. Results Genotype and allele frequencies did not differ between patients and controls for all polymorphisms investigated in this study. Haplotype analysis did not reveal any additional information. Conclusion We did not find evidence to support an influence of variation in genes encoding eosinophil granule proteins for AD pathogenesis in this German cohort.

    Full Text Available Griscelli syndrome (GS is a rare autosomal recessive disorder that results in pigmentary dilution of the skin and the hair (silver hair, with the presence of large clumps of pigment in hair shafts, and an accumulation of melanosomes in melanocytes. Sixty cases of GS have been reported in the literature, but we could find no description of its oro-dental symptoms. Reye′s syndrome (RS is characterized by acute noninflammatory encephalopathy and renal and hepatic failure, while atopic dermatitis (AD is a skin disorder with an immunologic basis. The aim of this paper is to describe the oro-dental and physical findings in a girl who had been diagnosed with GS at 3.5 years of age; she also had AD as well as a history of RS at infancy. We discuss the possible relationship between the three syndromes.

    Silymarin is a naturally occurring flavonoid drug; evidence from recent research has highlighted its use as a potential treatment for atopic dermatitis (AD). Both poor water solubility and drug permeability have hindered the percutaneous absorption of silymarin. Formulation of silymarin into pluronic-lecithin organogel (PLO) basis for topical skin delivery is the main aim of this work. Six different PLO formulations were prepared containing various pluronic to lecithin ratios using two cosolvent systems of ethyl alcohol and dimethyl sulfoxide. Formulation 2 (20% pluronic and 3% lecithin) was found to be the optimal base for topical delivery of silymarin as it showed optimum pH, viscosity, drug content, and satisfactory in vitro silymarin permeation. The silymarin PLO formulation significantly relieved inflammatory symptoms of AD such as redness, swelling, and inflammation. These findings warrant the ability for application of these novel silymarin PLO formulations as a novel treatment for AD. PMID:27022248

    Topical corticosteroids (TCS) are regarded as the mainstay treatment for atopic dermatitis (AD). As AD has a tendency to heal naturally, the long-term efficacy of TCS in AD management should be compared with the outcomes seen in patients with AD not using TCS. However, there are few long-term studies that consider patients with AD not using TCS. We designed a prospective multicenter cohort study to assess the clinical outcomes in patients with AD who did not use TCS for 6 months and then compared our results with an earlier study by Furue et al which considered AD patients using TCS over 6 months. Our patients’ clinical improvement was comparable with the patients described in Furue’s research. In light of this, it is reasonable for physicians to manage AD patients who decline TCS, as the expected long-term prognosis is similar whether they use TCS or not. PMID:27445501

    Vitamin D influences allergen-induced pathways in the innate and adaptive immune system, and its potential immunomodulatory role in allergic skin disorders has been explored. This comprehensive review article provides an overview of the role of vitamin D in three common dermatologic conditions: atopic dermatitis (AD), chronic urticaria, and allergic contact dermatitis (ACD). Whereas the literature regarding vitamin D and AD has resulted in mixed findings, several studies have described an inverse relationship between vitamin D levels and AD severity, and improvement in AD with vitamin D supplementation. Similarly, several studies report an inverse relationship between vitamin D levels and severity of chronic urticaria. Although current research in humans remains limited, an increased likelihood of ACD has been demonstrated in vitamin D-deficient mice. Additional well-designed clinical trials will be necessary to determine whether vitamin D supplementation should be recommended for prevention or adjuvant treatment of these common dermatologic conditions.

    Atopic dermatitis (AD) is the most common inflammatory skin disease. Recent research findings have provided an insight into the complex pathogenic mechanisms involved in this disease. Despite a rising prevalence, effective and safe therapeutics for patients with moderate-to-severe AD are still lacking. Biomarkers of lesional, nonlesional skin, and blood have been developed for baseline as well as after treatment with broad and specific treatments (i.e., cyclosporine A and dupilumab). These biomarkers will help with the development of novel targeted therapeutics and assessment of disease reversal, with the promise of a more personalized treatment approach. Since AD involves more than one subtype (i.e., intrinsic/extrinsic, pediatric/adult, etc.), these molecular fingerprints needs to be validated in all subpopulations with AD.

    Full Text Available Atopic dermatitis is a chronic inflammatory skin disease. Multiple genetic and environmental factors are thought to be responsible for susceptibility to AD. In this study, we collected 2,478 DNA samples including 209 AD patients and 729 control subjects from Taiwanese population and 513 AD patients and 1027 control subject from Japanese population for sequencing and genotyping ORAI1. A total of 14 genetic variants including 3 novel single-nucleotide polymorphisms (SNPs in the ORAI1 gene were identified. Our results indicated that a non-synonymous SNP (rs3741596, Ser218Gly associated with the susceptibility of AD in the Japanese population but not in the Taiwanese population. However, there is another SNP of ORAI1 (rs3741595 associated with the risk of AD in the Taiwanese population but not in the Japanese population. Taken together, our results indicated that genetic polymorphisms of ORAI1 are very likely to be involved in the susceptibility of AD.

    Full Text Available Herbs are widely used in the treatment of atopic dermatitis (AD in Eastern Asian countries, and certain herbs regarded have anti-inflammatory properties that can help with AD. With the goal of developing a topical herbal agent for AD, we conducted a systematic review of in vivo studies of AD-like skin models for screening potential herbs. Searches were conducted from PubMed and EMBASE. After all, 22 studies were included for this review. We judged most of the domains of all studies to be at unclear risk of bias. Among 22 included studies, 21 herbs have been reported to reduce AD-like skin lesions in mouse models by suppressing Th2 cell response. Our findings may offer potential herbs for the topical application treatment of AD.

    Introduction: Severe atopic dermatitis (AD) usually has a psychiatric component that may influence the course of the cutaneous symptoms. Functional neuroimaging could evidence brain dysfunctions in this kind of patients. Objective: Evaluate the presence and characteristics of cerebral perfusion changes in severe AD patients using SPECT. Materials and methods: 11 severe AD patients were subjected to clinical psychiatric evaluation and 99mTc-ECD SPECT. Results: 90.3% of the patients presented a generalized anxiety disorder, 63.6% an obsessive compulsive disorder and 63.6% a depression. The 11 patients presented perfusion changes that prevailed at the prefrontal cortex. The alterations were concordant with the patterns described in those patients in which anxiety disorders and depression coexist. Conclusions: We demonstrate the frequent presence of perfusion changes in severe AD patients with psychiatric symptoms (au)

    The authors study the yields of charged kaons, charged pions, and protons produced in association with B mesons produced in proton-antiproton collisions at center of mass energy 1960 GeV using 355 pb-1 of data collected with the CDF detector at the Fermilab Tevatron. This is the first reported measurements of these yields at a hadron collider. The B mesons are reconstructed using their semileptonic decays: B0 → ℓ+D-X, D- → K+π-π-; B0 → ℓ+D*-X, D*- → π-$\\bar{D}$0,$\\bar{D}$0 → K+π-; B+ → ℓ+$\\bar{D}$0X, $\\bar{D}$0 → K+π-; Bs→ℓ+D$-\\atop{s}$ X, D$-\\atop{s}$ → π-Φ,Φ → K+K-. The K, π, and p are identified using the Time of Flight detector (TOF), the CDF spectrometer, and the specific ionization (dE/dx) measured in the central drift chamber (COT). The fraction of charged kaons produced in association with $\\bar{B}$$0\\atop{s}$ mesons is found to be larger than the fraction produced in association with the $\\bar{B}$$0\\atop{s}$ and B- mesons, as expected from naive models of heavy quark hadronization to mesons. The particle species yields are found to be in qualitative agreement with simulation of B meson production in hadron collisions from the PYTHIA Monte Carlo, although the yield of kaons around $\\bar{B}$$0\\atop{s}$ mesons is found to be larger in the simulation when compared to the data. These studies are important for understanding methods of identifying the flavor of $\\bar{B}$$0\\atop{s}$ mesons in measurement of $\\bar{B}$$0\\atop{s}$ flavor oscillations and charge conjugation-parity (CP) violation in $\\bar{B}$$0\\atop{s}$ meson decays.

    2008-01-01

    Full Text Available Background: Atopic dermatitis (AD is a chronic, relapsing, itchy dermatosis of multifactorial origin, which commonly starts in childhood. Defective metabolism of essential fatty acids leading to relative dominance of pro-inflammatory prostaglandins (PGE 2 and PGF 2 has been reported as an important factor in the pathogenesis of AD. Evening primrose oil (EPO as a source of gamma-linolenic acid (GLA has been of interest in the management of AD. Aim: To evaluate the efficacy and safety of EPO in atopic dermatitis in our patients. Methods: Consecutive new out-patient department (OPD patients of a referral hospital in Kolkata clinically diagnosed as having AD were randomly allocated to two groups. To the first group, evening primrose oil was supplied as 500-mg oval clear unmarked capsules, while placebo capsules identical in appearance and containing 300 mg of sunflower oil were given to the other group. Treatment continued for a period of 5 months. With pre-designed scoring system (based on four major parameters: extent, intensity, itching, and dryness, clinical evaluation was done at baseline and subsequent monthly visits. Data of the first 25 patients from each group who completed the 5 months of trial were compiled and analyzed. Results: At the end of the fifth month, 24 (96% patients of EPO group and 8 (32% patients of placebo group showed improvement. There was significant difference in outcome of treatment between two groups (P < 0.00001. No significant adverse effect was reported by any patient/guardian at any point of assessment. Conclusion: Evening primrose oil is a safe and effective medicine in management of AD. However, since not all researchers across the world have found the same good result, further large trials on Indian patients are needed.

  2. Effect of partial melting on small scale convection atop a mantle plume

    Agrusta, R.; Arcay, D.; Tommasi, A.; Gonzalez, A.

    2014-12-01

    A lithospheric plate passing atop a mantle plume is likely to be thermally thinned or "rejuvenated". Geophysical data on the lithosphere-asthenosphere boundary (LAB) depth beneath active hotspots partly validate this prediction, but there is a large variation of the LAB upwelling estimated from different methods. Numerical simulations of plume-lithosphere interactions show that the development of small-scale convection (SSC) in the plume pancake spreading out along the base of the lithosphere is a mechanism able to rejuvenate the lithosphere, even for a fast-moving plate. The triggering of SSC has been shown to depend on the rheological behaviour of the unstable layer underlying the stagnant upper part of the thermal boundary layer (TBL), but the stability of the this layer may also be affected by partial melting.We analyze, using a 2D petrological-thermo-mechanical numerical model, the influence of partial melting on the dynamics of time-dependent SSC instabilities and the resulting rejuvenation of a lithosphere passing atop a mantle plume. These models show a complex behavior, with either an acceleration, no change or a slight decceleration of the SSC onset, due to the competing effects of the latent heat of melting, which cools the plume material, and of the buoyancy increase associated with melting, among which the dominant effect is the depletion in heavy elements of the solid fraction. The viscosity reduction, though significant (up to 2 orders of magnitude) is too localized to affect the SSC dynamics. Despite the presence of partial melting, the mechanical lithosphere erosion in not enhanced significantly relatively to melt-free models.

    Quantitative questionnaire-based research has suggested a considerable effect of skin disease on the sexual life of sufferers. In this study, we explored the effects of acne, psoriasis and atopic eczema upon sexual functioning and sexual relationships in the context of a wider exploration of the psychological sequelae of these diseases. We employed a qualitative methodology employing in-depth semi-structured interviews and involving thematic analysis and constant comparison. Participants were patients with currently active acne, psoriasis or atopic eczema. Purposive sampling aimed to obtain a sample reflecting a wide range of participant characteristics including skin disease severity, age, sex, and care by general practitioner or dermatologist. Sixty-two semi-structured interviews were conducted. Acne had adverse effects on participants' self-perceived sexual attractiveness and self-confidence, as did psoriasis and eczema. But psoriasis and eczema also had marked effects on sexual well-being and on capacity for intimacy. These were related to issues of self-esteem and sexual self-image and were often pervasive, resulting in marked behavioural avoidance of intimate situations and continuing effects on sexual well-being even in long-established sexual relationships. Effects of psoriasis and eczema on sexual well-being and sexual relationships were mediated more by appearance and texture of non-genital skin than by involvement of genital skin. We conclude that, while recognising the distressing effects of acne on self-perceived sexual attractiveness, clinicians should be especially aware of the capacity of psoriasis and eczema to profoundly affect patients' psychological and sexual well-being.

    Full Text Available Abstract Background Allergy represents a risk factor at the base of sleep-disordered breathing in pediatric age. Among allergic diseases, the atopy is characterized by a tendency to be “hyperallergic.” Sleep-disordered breathing is also known in orthodontics as correlated with the morphology of craniofacial complex. The aim of this study was to investigate the relation between atopy and sleep-disordered breathing (oral breathers with habitual snoring, comparing atopic children with sleep-disordered breathing (test group with nonatopic ones with sleep-disordered breathing (control group, in the prevalence of dento-skeletal alterations and other risk factors that trigger sleep-disordered breathing, such as adenotonsillar hypertrophy, turbinate hypertrophy, obesity, and alteration of oxygen arterial saturation. Methods In a group of 110 subjects with sleep-disordered breathing (6 to 12 years old, we grouped the subjects into atopic (test group, 60 subjects and nonatopic (control group, 50 subjects children and compared the data on the following: skin allergic tests, rhinoscopy, rhinomanometry, night home pulsoxymetry, body mass index, and dento-facial alterations. Results Even if our results suggest that atopy is not a direct risk factor for sleep-disordered breathing, the importance of a physiologic nasal respiration in the pathogenesis of sleep-disordered breathing seems to be demonstrated in our study by the higher prevalence of hypertrophy in the adenotonsillar lymphatic tissue, odontostomatological alterations, alterations of the oxygen saturation to pulsoxymetry, and higher prevalence of obesity observed in our children with sleep-disordered breathing, in percentages higher than that of the general pediatric population previously observed in the literature. Conclusions The importance of a physiologic nasal respiration in the pathogenesis of sleep-disordered breathing is demonstrated in our study.

    Objective. Atopie asthma provides a usetul model for evaluating the genetic tactors that control human immune responsiveness. HLA class Ⅱ gene products are involved in the control of immune response. As HLA-DRB gene is the most polymorphic HLA class Ⅱ gene, we investigated whether susceptibility or resistance to the disease is associated with HLA-DRB. Methods. Blood samples were obtained from two groups of unrelated Chinese northern adults: (1) 50 atopic asthma (7 of them with familial aggregation) ; (2) 80 healthy controls without asthma or atopy and other HLA-associated diseases. Genomic DNA was extracted from peripheral venous blood leucocytes. The polymorphie second exon of HLA-DRB gene was amplified by sequence-specific primer polymerase chain reaction (SSP/PCR) methods. All patients had their serum IgE(total and spscifie) antibody levels by RAST, bronchial reactivity assessed by methaeholine brocho-provocation test and/or hronchodilation test. Results.There was an increased gene frequency of DR52 and DR52 in asthmatic subjects compared with healthy subjects(17% vs 4.3%, P<0. 01% 50% vs 17.5%, P<0. 01), and the decreased frequency of DR2(15) and DR52 in asthmatic patients(7% vs 18%, P<0. 05; 2% vs 33%, P<0. 01). We found the positive association between DR5(13)-DR52 and sIgE antibody responsiveness to d1 (from house dust mite allergen ); negative association between HLA-DRB alleles and TIgE or BHR ( bronchial hyperresponsiveness). Conclusion. The results suggested that HLA haplotype DR6(13)-DR52 was significantly implicated in suseeptibility to house dust mite induced-asthma, at least it would he more closely assocaated with atopic asthms. Conversely, alleles DR2(15) and DR51 might corder protection against the disease. HLA-DRB genes were particularly involved in regulating human atopie immune response in asthma.

    Full Text Available Abstract Background The impact of atopic dermatitis (AD on children's quality of life (QoL in US and European countries is relatively well known, though rarely evaluated in the Italian population. Moreover, the association between child age and QoL has not been enough investigated, even though few studies detected a worse QoL in youngest AD children. The aim of the study was to evaluate the QoL in an Italian sample of atopic children and their families, also exploring a possible association with child age. Methods 60 AD children aged between 1-12 years and their mothers completed specific QoL questionnaires (IDQoL/CDLQI, DFI and a clinician completed a measure of AD severity (SCORAD. Results AD severity (Objective SCORAD significantly correlated with QoL measures. Severe AD children showed higher IDQoL/CDLQI and DFI scores compared to mild and moderate AD groups (P = 0.006 and P P = 0.014. DFI scores negatively correlated with children's age (P = 0.046, but did not differ when considering child age ranges. Multiple linear regression analyses revealed a significant association between Objective SCORAD and QoL measures. Conclusions A strong association between severe AD and poor QoL, both in children and mothers, was found in the Italian sample, in line with the international literature. Family's QoL scores were sensitively related to AD severity, more than the child's QoL, emphasising that the disease has a deep impact on the family. A significant association between age and QoL was only partially found and needs further investigation.

    Full Text Available It was examined 40 patients with atopic dermatitis in various stages of the clinical course of dermatosis. It has revealed typical endoscopic changes of the gastrointestinal tract in patients with atopic dermatitis in quiescent and acute stages. It has studied the cellular composition of infiltrates and histomorphology of mucous coat of stomach and distal part of sigmoid colon. It has found the generic dysbiotic malfunctions of intestinal microflora in different periods of the clinical course of dermatosis. It is suggested an assumption about the relations between morphological changes of mucous coat of stomach and distal part of sigmoid colon in patients with atopic dermatitis with symtomatic dysbiotic disorders of the intestine and the severity of skin lesions in atopic dermatitis.

    Full Text Available BACKGROUND: Atopic dermatitis has increased four-fold over the recent decades in developed countries, indicating that changes in environmental factors associated with lifestyle may play an important role in this epidemic. It has been proposed that alcohol consumption may be one contributing risk factor in this development. OBJECTIVE: To analyze the impact of alcohol intake during pregnancy on the development of atopic dermatitis during the first 7 years of life. METHOD: The COPSAC cohort is a prospective, longitudinal, birth cohort study of 411 children born to mothers with a history of asthma, followed up for 7 years with scheduled visits every 6 months as well as visits for acute exacerbations of atopic dermatitis. Risk of atopic dermatitis from any alcohol consumption during pregnancy was analyzed as time-to-diagnosis and adjusted for known risk factors. RESULTS: 177 of 411 children developed atopic dermatitis before age 7 years. We found a significant effect of alcohol intake during pregnancy on atopic dermatitis development (HR 1.44, 95% CI 1.05-1.99 p=0.024. This conclusion was unaffected after adjustment for smoking, mother's education and mother's atopic dermatitis. LIMITATIONS: The selection of a high-risk cohort, with all mothers suffering from asthma, and all children having a gestational age above 35 weeks with no congenital abnormality, systemic illness, or history of mechanical ventilation or lower airway infection. CONCLUSION: Alcohol intake by pregnant women with a history of asthma, is significantly associated with an increased risk for the child for developing atopic dermatitis during the first 7 years of life.

    Background Evidence that atopic eczema partly originates in utero is increasing, with some studies linking the risk of developing the condition with aspects of maternal diet during pregnancy. Nicotinamide, a naturally occurring nutrient that is maintained through the dietary intakes of vitamin B3 and tryptophan has been used in the treatment of some skin conditions including atopic eczema. Objective To examine the relation of maternal serum concentrations of nicotinamide and related tryptophan metabolites to the risk of atopic eczema in the offspring. Methods Within the UK Southampton Women Survey, infantile atopic eczema at ages 6 and 12 months was ascertained (modified UK Working Party Criteria for the Definition of Atopic Dermatitis). Maternal serum levels of kynurenine, kynurenic acid, anthranilic acid, tryptophan, nicotinamide and N1-methylnicotinamide were measured in late pregnancy by mass spectrometry, n=497 and related to the odds ratio of infantile atopic eczema. Results Maternal nicotinamide and related metabolite concentrations were not associated with offspring atopic eczema at age 6 months. Higher concentrations of nicotinamide and anthranilic acid were, however, associated with a lower risk of eczema at age 12 months (odds ratios 0.69, 95% CI 0.53-0.91 /SD change, p=0.007 and 0.63, 0.48-0.83, p=0.001, respectively). The associations were robust to adjustment for potentially confounding variables. Conclusion and clinical relevance This is the first study linking maternal serum concentrations of nicotinamide and related metabolites to the risk of atopic eczema in the offspring. The findings point to potentially modifiable maternal influences on this complex and highly prevalent condition. PMID:27517618

    Allergic skin inflammation such as atopic dermatitis is characterized by skin barrier dysfunction, edema, and infiltration with various inflammatory cells. The anti-inflammatory effects of Apo-9'-fucoxanthinone, isolated from Sargassum muticum, have been described in many diseases, but the mechanism by which it modulates the immune system is poorly understood. In this study, the ability of Apo-9'-fucoxanthinone to suppress allergic reactions was investigated using a mouse model of atopic dermatitis. The Apo-9'-fucoxanthinone-treated group showed significantly decreased immunoglobulin E in serum. Also, Apo-9'-fucoxanthinone treatment resulted in a smaller lymph node size with reduced the thickness and length compared to the induction group. In addition, Apo-9'-fucoxanthinone inhibited the expression of interleukin-4, interferon-gamma and tumor necrosis factor-alpha by phorbol 12-myristate 13-acetate and ionomycin-stimulated lymphocytes. These results suggest that Apo-9'-fucoxanthinone may be a useful therapeutic strategy for treating chronic inflammatory diseases. PMID:27123161

    Full Text Available The aim of the investigation was to study the state of immunologic responsiveness, immunomodulating and anti-relapse effects of ozone therapy in children with severe extended atopic dermatitis. Materials and Methods. We examined 64 children (38 boys and 26 girls aged 5–10 years with severe extended atopic dermatitis. Group 1 patients (n=33 received complex standard treatment, Group 2 (n=31 — complex therapy in combination with ozone therapy. Results. Complex standard therapy resulted in complete, though short, clinical remission; and in remission the patients preserved the changed parameters of cellular and humoral components of immune system, nonspecific resistance and the levels of pro-inflammatory cytokines in blood serum; while the patients receiving complex therapy combined with ozone therapy were found to have more rapid improvement of clinical indices, normalization of the most parameters of immunologic responsiveness and a long clinical remission.

    Isolates of the yeast Malassezia pachydermatis obtained from skin samples of healthy dogs and of dogs with atopic dermatitis in Japan, Taiwan and Korea were molecularly characterized using intergenic pacer 1 (IGS1) region analysis. The percentage of IGS1 subtype isolates detected in healthy skin was as follows: 1A (6%), 1B (27%), 1C (11%), 2A (6%), 2B (6%), 3A (11%), 3B (6%), 3C (3%) and 3D (24%). In contrast, the most prevalent isolates detected in skin lesions of atopic dermatitis were subtype 3D in Japan and Taiwan and subtype 3C in Korea. All subtype isolates grew well on acidic medium (pH 6). However, subtype 3C and 3D isolates grew better than the other subtype isolates on medium at pH 8. PMID:23411408

    Full Text Available The ethanolic extract of Lentinula edodes was partially analyzed and then characterized for its efficacy in treating atopic dermatitis. Polyphenols were determined to be the major antioxidant component in the extract (6.12 mg/g, followed by flavonoids (1.76 mg/g, β-carotene (28.75 μg/g, and lycopene (5.25 μg/g. An atopic dermatitis (AD model was established and epidermal and dermal ear thickness, mast cell infiltration, and serum immunoglobulin levels were measured after oral administration of the L. edodes extract for 4 weeks. L. edodes extract decreased Dermatophagoides farinae extract (DFE and 4-dinitrochlorobenzene (DNCB-induced expression of several inflammatory cytokines in the ears, cervical lymph nodes, and splenocytes. Consequently, L. edodes extract may have therapeutic potential in the treatment of AD attributable to its immunomodulatory effects.

    This double-blind study determined whether daily bathing with an antibacterial soap would reduce the number of Staphylococcus aureus on the skin and result in clinical improvement of atopic dermatitis. For 9 weeks, 50 patients with moderately severe atopic dermatitis bathed daily with either an antimicrobial soap containing 1.5% triclocarban or the placebo soap. They also used a nonmedicated moisturizer and 0.025% triamcinolone acetonide cream as needed, but the availability of the corticosteroid cream was discontinued after 6 weeks. The antimicrobial soap regimen caused significantly greater improvement in the severity and extent of skin lesions than the placebo soap regimen, which correlated with reductions both in S aureus in patients with positive cultures at baseline and in total aerobic organisms. Outcome measures included reductions in S aureus, total aerobic organisms, and dermatologic assessments. Overall, daily bathing with an antibacterial soap was well tolerated, provided clinical improvement, and reduced levels of skin microorganisms. PMID:11109156
