Polysensitizations to tree, grass, and weed pollen are found in ~ 20% of pollen-allergic individuals. They are often based on broad IgE cross-reactivities to pollen panallergens belonging to highly conserved protein families 1. profilins, 2. polcalcins (calcium-binding proteins in pollen), 3. cyclophilins. They represent highly conserved cross-reactive minor allergens present in all pollen species, but also in plant foods and other organisms. Despite being rarely clinically relevant they can hamper allergy diagnostic tests with extracts. In this situation, molecular allergy diagnosis is able to distinguish broad cross-reactivity due to allergen-specific IgE to pollen panallergens (i.e. profilins Bet v 2 or Phl p 12; polcalcins Bet v 4 or Phl p 7; and, in the future, cyclophilins Bet v 7 or Ole e 15) from primary IgE sensitizations to so-called marker allergens represented by important pollen major allergens Bet v 1 for the birch and beech family (Fagales), Ole e 1 for olive and ash (Oleaceae), Phl p 1 for temperate climate grasses (Poaceae), Art v 1 for mugwort (Artemisia), Amb a 1 for Ambrosia species (Ambrosia). Five typical cases (A - E) with positive skin prick test results to tree, grass, and weed pollen extracts demonstrate typical patterns of IgE sensitization with a variable impact of pollen panallergens A - profilins, B - polcalcins, C - profilins and polcalcins, D - presumably cyclophilins, E - primary polysensitization to tree, grass, and weed pollen without interference from profilins or polcalcins. Differences between pollen extract-based skin prick test diagnosis and molecular allergen-specific IgE testing are explained using the presented concept. This approach allows to reduce the number of allergen extracts - presuming they are also clinically relevant - for allergen immunotherapy (i.e., only tree and/or grass pollen extracts), particularly in pollen-polysensitized patients.An expert workshop in collaboration of the German Society of Allergy and Clinical Immunology (DGAKI) and the Japanese Society of Allergy (JSA) provided a platform for key opinion leaders of both countries aimed to join expertise and to highlight current developments and achievements in allergy research. Key domains of the meeting included the following seven main sections and related subchapters 1) basic immunology, 2) bronchial asthma, 3) prevention of allergic diseases, 4) food allergy and anaphylaxis, 5) atopic dermatitis, 6) venom allergy, and 7) upper airway diseases. This report provides a summary of panel discussions of all seven domains and highlights unmet needs and project possibilities of enhanced collaborations of scientific projects.In the workup of a 55-year-old atopic patient with cough and viscous secretions, we diagnosed an allergic bronchopulmonary aspergillosis (ABPA) on the basis of common diagnostic criteria for adult asthma patients (Rosenberg-Patterson and ISHAM), supported by the use of IgE antibodies against the Aspergillus components Asp f 2, f 4, and f 6. Initial treatment with prednisolone and itraconazole led to remission. In the long-term follow-up, there were few relapses until 2015, which responded well to standard treatment with oral steroids, and since 2016 the patient is in stable remission. The case highlights the valuable contribution of Aspergillus IgE measurements, including the specific IgEs against the components Asp f 1, f 2, f 4, and f 6 in the diagnosis of ABPA.
The associated risk factors, co-morbid conditions and biological differences varying with gender and age might be the cause of higher COVID-19 infection and deaths among males and older persons. The objective of this study was to predict and specify the biological attributes of variation in age and gender-based on COVID-19 status (deceased/recovered).
In this retrospective study, the data was extracted from a recognised web-based portal. A total of 112,860 patients' record was filtered out and an additional 9131 records were separately analysed to examine age and gender relationship with patient's COVID-19 status (recovered/deceased). Chi-square,
-test, binary logistic regression, and longitudinal regression analysis were conducted.
The male COVID-19 cases (65.39%) were more than females (34.61%) and mean age of infected and recovered patients was 39.47±17.59 years and 36.85±18.51 years respectively. The odds for infection was significantly higher among females for lower age categories, which declines with age. find more The age-adjusted odds for recovery were significantly higher among females (O.R.=1.779) and odds for recovery was highest in 5-17 years age category (O.R.=88.286) independent of gender.
The chances of being COVID-19 infected was higher for females of lower age categories (<35 years) which decreases with age. The odds for recovery among females was significantly higher than males. The chances of recovery declines with increasing age and the variation could be attributed to the biological differences between age categories and gender.
The chances of being COVID-19 infected was higher for females of lower age categories ( less then 35 years) which decreases with age. The odds for recovery among females was significantly higher than males. The chances of recovery declines with increasing age and the variation could be attributed to the biological differences between age categories and gender.
To understand how a child with a stable chronic disease and his/her parents shape his/her daily life participation, we assessed (1) the parents' goals regarding the child's daily life participation, (2) parental strategies regarding the child's participation and () how children and their parents interrelate when their goals regarding participation are not aligned.
This was a qualitative study design using a general inductive approach. Families of children 8-19 years with a stable chronic disease (cystic fibrosis, autoimmune disease or postcancer treatment) were recruited from the PROactive study. Simultaneous in-depth interviews were conducted separately with the child and parent(s). Analyses included constant comparison, coding and categorisation.
Thirty-one of the 57 invited families (54%) participated. We found that parents predominantly focus on securing their child's well-being, using participation as a means to achieve well-being. Moreover, parents used different strategies to either support participation consistent with the child's healthy peers or support participation with a focus on physical well-being.
