Fungal sinusitis or fungal rhinosinusitis is the inflammation of the lining mucosa of the paranasal sinuses due to a fungal infection. [1] [2] It occurs in people with reduced immunity. The maxillary sinus is the most commonly involved. Fungi responsible for fungal sinusitis are Aspergillus fumigatus (90%), Aspergillus flavus, and Aspergillus ...
1–15% of cystic fibrosis patients and 2.5% of adults with severe asthma. [ 3 ] Allergic bronchopulmonary aspergillosis ( ABPA ) is a condition characterised by an exaggerated response of the immune system (a hypersensitivity response ) to the fungus Aspergillus (most commonly Aspergillus fumigatus ).
Aspergillosis is thought to affect more than 14 million people worldwide, with allergic bronchopulmonary aspergillosis (ABPA) infecting about 4 million, severe asthma with fungal sensitization affecting about 6.5 million, and chronic pulmonary aspergillosis (CPA) infecting about 3 million people, considerably more than invasive aspergillosis ...
Mucormycosis, also known as black fungus, [3] [4] is a severe fungal infection [11] that comes under fulminant fungal sinusitis, [12] usually in people who are immunocompromised. [9] [13] It is curable only when diagnosed early. [12] Symptoms depend on where in the body the infection occurs.
Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever. [6] [7] Sinusitis is a condition that affects both children and adults.
Because sinusitis typically is preceded by an infection of the nasal mucosa, some authors suggest generally replacing the term “sinusitis” with “rhinosinusitis”. [1] The functional unity of the two mucosa speaks in favor of this replacement. A distinction is made between acute and chronic rhinosinusitis.
Type III hypersensitivity, in the Gell and Coombs classification of allergic reactions, occurs when there is accumulation of immune complexes (antigen-antibody complexes) that have not been adequately cleared by innate immune cells, giving rise to an inflammatory response and attraction of leukocytes. There are three steps that lead to this ...
Type I hypersensitivity (or immediate hypersensitivity), in the Gell and Coombs classification of allergic reactions, is an allergic reaction provoked by re-exposure to a specific type of antigen referred to as an allergen. [1] Type I is distinct from type II, type III and type IV hypersensitivities. The relevance of the Gell and Coombs ...
