2,475 Possible Causes for Anaphylaxis, Dermatographia, Hypersensitive to Stimuli

  • Urticaria

    Commonly, acute urticaria has an allergic basis as a type I hypersensitivity state mediated by IgE.[apps.who.int] We report four patients with severe antihistamine-resistant CSU, who developed angioedema, anaphylaxis and/or flare up of urticaria at different times following omalizumab[ncbi.nlm.nih.gov] Other causes include: infections, including viruses exercise anxiety or stress sun exposure exposure to cold, such as cold water or snow contact with chemicals scratching (dermatographia[kidshealth.org]

  • Systemic Mastocytosis

    anaphylaxis symptoms.[ncbi.nlm.nih.gov] […] usually occurs as a solitary lesion in infants. systemic mastocytosis signs and symptoms: constitutional; fatigue, fever, weight loss skin manifestations; urticaria, pruritus, dermatographia[e-immunohistochemistry.info] When activated by IgE or other stimuli, mast cells release preformed mediators of inflammation.[aafp.org]

  • Nonallergic Urticaria

    […] to physical stimuli such as scratching, friction from clothing or other objects, light, heat, cold, water or vibration Autoimmune conditions such as systemic lupus erythematosus[bpac.org.nz] Complications Chronic hives don't put you at any sudden risk of a serious allergic reaction (anaphylaxis).[mayoclinic.org] Other causes include: infections, including viruses exercise anxiety or stress sun exposure exposure to cold, such as cold water or snow contact with chemicals scratching (dermatographia[kidshealth.org]

  • Angioedema

    […] from external stimuli eg food, drugs, insect stings, pollen, animal dander; patients with known atopic conditions (asthma, eczema, hay fever, urticarial) are at higher risk[entsho.com] Recognize the signs and symptoms of anaphylaxis and be able to deliver rapid, effective treatment for anaphylaxis.[pedsinreview.aappublications.org] ., dermatographia or cold urticaria) in that histologic studies reveal a prominent cellular infiltrate around small venules, with an increased number of mast cells.[worldallergy.org]

  • Hypersensitivity

    […] marked sensitivity/reactivity to innocuous stimuli hypersensitivity An excessive reaction, local or systemic, or inappropriate immune response to an antigen.[medical-dictionary.thefreedictionary.com] This review highlights some of the research advances in anaphylaxis and hypersensitivity reactions to foods, drugs, and insects and in allergic skin disease that were reported[ncbi.nlm.nih.gov] Read more… Why is Anaphylaxis Awareness Week Important?

  • Diffuse Cutaneous Mastocytosis

    When activated by IgE or other stimuli, mast cells release preformed mediators of inflammation.[aafp.org] We decided to characterize clinical manifestations, the frequency of MCs mediator-related symptoms and anaphylaxis, risk of systemic mastocytosis (SM) and prognosis, based[ncbi.nlm.nih.gov] Darier’s sign was negative, but dermatographia was evident. KOH (potassium hydroxide) preparation was negative for dermatophytosis or candidiasis.[omicsonline.org]

  • Mastocytosis

    Activation by immunoglobulin E or other stimuli causes the mast cells to degranulate and release preformed mediators of inflammation that initiate the acute and delayed hypersensitivity[nature.com] Mortz, Patterns of anaphylaxis after diagnostic workup: A follow‐up study of 226 patients with suspected anaphylaxis, Allergy, 72, 12, (1944-1952), (2017). T.[doi.org] […] usually occurs as a solitary lesion in infants. systemic mastocytosis signs and symptoms: constitutional; fatigue, fever, weight loss skin manifestations; urticaria, pruritus, dermatographia[e-immunohistochemistry.info]

  • Cutaneous Mastocytosis

    Family counselled about chance of anaphylaxis to various toxins and drugs and risk of development of systemic mastocytosis.[ncbi.nlm.nih.gov] Darier’s sign was negative, but dermatographia was evident. KOH (potassium hydroxide) preparation was negative for dermatophytosis or candidiasis.[omicsonline.org] When activated by IgE or other stimuli, mast cells release preformed mediators of inflammation.[aafp.org]

  • Atopy

    Biological hypersensitivity to environmental stimuli, a fundamental feature of atopy, contributes to a spectrum of costly pediatric disorders, including allergic rhinitis,[doi.org] […] of anaphylaxis and stocking of epinephrine autoinjectors.[ncbi.nlm.nih.gov] You can be assured that as of now there is no known association between IBS and anaphylaxis risk.

  • Telangiectasia Macularis Eruptiva Perstans

    When activated by IgE or other stimuli, mast cells release preformed mediators of inflammation.[aafp.org] , the same principles would apply in a patient exhibiting idiopathic episodes of anaphylaxis. 4.[aaaai.org] She did not have dermatographia. White blood cell count was 6.8 10 3 /μL, with 19% monocytes and 1% eosinophils.[current-oncology.com]
