• #8 What Are Nasal Polyps? Symptoms, Causes, Diagnosis, Treatment, and Prevention

  https://www.everydayhealth.com/ear-nose-throat/nasal-polyps-symptoms-causes-diagnosis-treatment-prevention/

  Nasal polyps are a subgroup of chronic rhinosinusitis (CRS), which affects about 1 in 8 adults. CRS is characterized by inflammation of the nose and sinus cavities. About 20 percent of people with CRS have nasal polyps, which are benign growths in the nasal cavities that are thought to originate from the ethmoid sinuses (the hollow spaces in the bones around the nose). […] Prolonged inflammation of the lining of the nose and sinuses, also called chronic rhinosinusitis, is associated with nasal polyps, but its not completely clear what causes it, says Kim. The membranes become inflamed, which can include swelling, redness, and fluid buildup. This can continue for a long time or happen over and over again, she says. […] Tissue samples taken from nasal polyps have led some experts to believe that allergies and infections cause the inflammation. Those samples contained extra eosinophils, which are white blood cells linked to infections and allergic reactions. The resulting inflammation causes small growths filled with fluid that eventually turn into polyps.

• #9 Nasal Polyps Causes | Causes of Chronic Sinusitis

  https://resources.healthgrades.com/right-care/ear-nose-and-throat/6-conditions-that-cause-nasal-polyps

  Do you feel like you’ve caught a never-ending cold or a sinus infection that keeps coming back? There may be more going on in your nose than you think. Your symptoms may be caused by nasal polyps: soft, painless growths that hang down like teardrops on the lining of your nasal passages or sinuses. These pile on inflammation and block airways. Nasal polyps are not cancer, but they do need to be addressed. Learn about conditions that can contribute to or cause nasal polyps and have an informed conversation with your doctor about diagnosis and treatment. […] If your “sinus infection” goes on for weeks and months, you may have chronic sinusitis, also known as chronic rhinosinusitis or CRS. This condition puts you at greater risk of nasal polyps. In fact, about 20% of the millions of people around the world with chronic sinusitis also have nasal polyps.

  https://kingspharma.com/what-are-nasal-polyps-and-what-causes-them/

  Nasal polyps are soft, painless, noncancerous growths on your nasal passages or sinus lining. They result from chronic inflammation and are associated with asthma, recurring infection, allergies, drug sensitivity, or certain immune disorders. […] Polyps form when the mucous membranes that line the nose and sinuses alter. The membranes become irritated over an extended period of time or repeatedly. Swelling, redness, as well as fluid buildup are all symptoms of inflammation. […] According to researchers, inflammation is thought to be caused by allergies and infections. They believe this because they examined tissue from nasal polyps. Extra eosinophils, white cells connected to infections, as well as allergic responses were found in those samples. The evidence indicates too few fluid-filled growths that cause inflammation. Polyps form from these fluid-filled growths.

• #11 Nasal Polyps: Causes, Symptoms, Treatment, and Prevention

  Nasal polyps are noncancerous growths that develop in the lining of the nasal passages or sinuses. […] The exact cause of polyps in the nasal cavity remains a mystery. When the lining of the nasal passages or sinuses becomes inflamed, it can result in fluid accumulation within cells, leading to the formation of polyps. Several factors may contribute to the development of nasal polyp disease, including: Chronic Inflammation: Conditions like asthma, chronic rhinosinusitis, and allergic rhinitis can cause long-term inflammation in the nasal passages and sinuses. […] Genetic Predisposition: A family history of nasal polyps or related conditions can increase the chance of developing polyps. […] Allergies: Sensitivity to airborne allergens such as pollen, dust mites, or mold can also lead to chronic inflammation and polyp formation. […] Infections: Repeated respiratory infections can contribute to the inflammation of nasal passages, setting the stage for polyp development. […] Aspirin Sensitivity: Individuals with aspirin sensitivity, especially those with asthma, are at a higher risk of developing nasal polyps.

• #12 Nasal Polyps – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK560746/

  Nasal polyps are classified into 3 groups: localized, diffuse, and systemic. Localized nasal polyps are typically reactive and arise from either inflammatory or neoplastic processes. Diffuse nasal polyposis is often observed in patients with CRSwNP, which has multiple etiologies. In the Western Hemisphere, most cases of nasal polyps are the result of T-helper 2 (Th2) cell-driven eosinophilia and immunoglobulin E (IgE) inflammation, characterized by elevated interleukin-5 (IL-5). This pattern is often associated with environmental or seasonal allergic triggers. […] Patients with cystic fibrosis tend to exhibit neutrophil-driven inflammation within their polyps. These individuals may present with severe nasal polyposis in the absence of a clear allergic trigger, although the clinical appearance may closely resemble allergic disease. Cystic fibrosis should be considered in the differential diagnosis of refractory nasal polyposis in young patients, particularly preteens, teenagers, and young adults, which is especially relevant in patients of European ancestry. Prompt diagnosis is critical due to the systemic and genetic implications of cystic fibrosis.

  Nasal polyps tend to be present in both sides of the nasal cavity. […] The exact cause of chronic rhinosinusitis with nasal polyps (CRSwNP) is unknown but biopsy of nasal polyp tissue in the western population demonstrates an elevated allergic type of cells known as eosinophils. […] Infection may also play a role, especially by bacteria called Staphylococcus aureus. […] A subgroup of patients with asthma and nasal polyps develop worsening nasal symptoms and/or breathing problems upon ingestion of aspirin or other nonsteroidals. […] Allergic fungal rhinosinusitis (AFRS) is due to an allergic response to inhaled fungi in a predisposed individual with nasal polyps. […] Cystic fibrosis is another condition associated with nasal polyps. […] Nasal polyps are present in up to 86% of patients with cystic fibrosis.

• #14 A review of nasal polyposis

  https://pmc.ncbi.nlm.nih.gov/articles/PMC2504067/

  Many studies have focussed on eosinophilic mediators in NP tissue and demonstrated that different cell types generate these mediators. Interleukine-5 (IL-5) has found to be significantly raised in NP compared with healthy controls and the concentration of IL-5 was independent of the atopic status of the patient (Bachert et al 2001). […] An association between polyposis and fungal cultures has been established for many years (Safirstein et al 1976). Further reports linked this finding with allergic bronchopulmonary aspergillosis (Millar et al 1981). […] There is some evidence for a genetic element to NP. A link has been demonstrated recently between HLA-A74 and NP (Luxenburger et al 2000), but the current knowledge in this area remains very limited. […] Medical conditions commonly associated with polyps include asthma, bronchiectasis, and cystic fibrosis (Settipane et al 1996). There is a well recognized subgroup of patients with Samnters Triad comprising polyposis, asthma, and aspirin hypersensitivity which makes up almost 10% of cases of NP.

  https://patient.info/doctor/nasal-polyps-pro

  Nasal polyps have been linked with chronic inflammation such as in chronic rhinosinusitis and vasculitis. Superantigens produced by Staphylococcus aureus may play a role. Polyps usually start close to the ostiomeatal complex (the sinus ostia) of the nasopharynx. […] Recent research has identified differences in aetiology between chronic rhinitis with polyps and chronic rhinitis without polyps. Patients presenting with chronic rhinitis with polyps are found to have oedema of the nasal mucosa, low T regulatory cell activity and low levels of beta-tissue growth factor. Inflammatory mediators such as cytokines and chemokines may also have a role. […] Different factors may be involved, depending on factors such as geographical location, culture and differences in bacterial colonisation.

  Up to 39% of those with adult-onset asthma also have nasal polyps. The medical term for having nasal polyps and asthma is “nasal polyps and comorbid asthma,” or “NPcA.” NPcA is considered a severe united airway disease. […] A nasal allergy, or allergic rhinitis, causes inflammation in the nose that can lead to nasal polyps. […] Fungi in the environment can cause allergic fungal sinusitis (AFS). Like a nasal allergy, fungi cause inflammation in the nose. They also slow or block the drainage of mucus from the sinuses. AFS can lead to both nasal polyps and chronic sinusitis. […] Aspirin sensitivity can cause life-threatening breathing problems that may exacerbate nasal inflammation and encourage nasal polyps to form. […] Cystic fibrosis, or CF, is a genetic disorder that causes mucus to build up in the body and block the airways. This leads to lung infections, breathing problems, and nasal polyps. Nasal polyps develop in up to 60% of people who have cystic fibrosis.

• #18 Understanding Nasal Polyps | Suffern and Monroe, NY

  https://aacrockland.com/nasal-polyps-symptoms

  Nasal polyps are often associated with chronic inflammation in the nasal passages, commonly triggered by allergies such as hay fever, dust, or pet allergies, as well as asthma. The development of nasal polyps begins with prolonged irritation or inflammation of the mucous membranes in the nasal passages or sinuses. This persistent inflammation can cause the mucosa to swell and eventually form polyps. Certain factors, such as a family history of nasal polyps, chronic respiratory conditions, or sensitivities to aspirin, may increase the likelihood of developing these growths. […] Certain factors increase the likelihood of developing nasal polyps, ranging from chronic inflammatory conditions to genetic predispositions. Understanding these risk factors can help in identifying, managing, and preventing nasal polyps effectively. Below are the primary contributors to nasal polyp development: Chronic Rhinosinusitis: Persistent inflammation of the nasal and sinus linings often leads to the development of polyps. Chronic Sinusitis: Prolonged sinus infections can cause thickening of the nasal lining, increasing the risk of polyp formation. Asthma: The inflammation associated with asthma can overlap with nasal polyp development, creating a need for integrated care strategies. Aspirin-Exacerbated Respiratory Disease (AERD): This condition combines asthma, nasal polyps, and sensitivity to aspirin or NSAIDs, making it a common risk factor. Cystic Fibrosis: Individuals with cystic fibrosis often experience nasal polyps due to their conditions effects on mucus production and inflammation. Allergic Rhinitis and Fungal Sinusitis: Chronic allergies and fungal sinus infections contribute to inflammation, which may result in polyp development. Immunodeficiency: A weakened immune system can make individuals more susceptible to infections and chronic inflammation, increasing the risk of polyps. Medication Use: Certain medications, particularly those affecting inflammation or respiratory function, may exacerbate risks. Structural Issues: Deviated septum or other nasal structural problems can obstruct drainage, leading to chronic inflammation and polyp formation. Environmental Irritants: Prolonged exposure to allergens, pollutants, or irritants can aggravate nasal linings and contribute to polyp development. Genetic Risk: A family history of nasal polyps increases the likelihood of developing them. Age Factor: Nasal polyps are more commonly diagnosed in adults over 40, with age-appropriate care being a vital consideration.

  What causes nasal polyps? The short answer is inflammation. Polyps grow when there’s irritation in the mucosa that lines your nasal passages. Some conditions like sinus infections, allergies or asthma can cause your nasal mucosa to become swollen and inflamed. If your mucosa remains irritated for a long time, it may form a polyp. […] Anyone and people of all ages can get nasal polyps, but they are more common in adults. You’re also more likely to get nasal polyps if you have: Chronic or recurrent sinus infections Your risk of polyps increases if you have infections that don’t go away or keep coming back. Seasonal allergies or asthma If you have these conditions your nasal passages may often be inflamed, creating the perfect environment for polyps to grow. Low levels of vitamin D Having low vitamin D levels can lead to ongoing inflammation and make polyps grow more quickly. Cystic fibrosis This is because cystic fibrosis causes thicker and stickier mucus that can block your nasal passages, preventing drainage. Churg-Strauss syndrome If you have this condition, your blood vessels, including those in your nose, may be inflamed. Sensitivity to aspirin or other over-the-counter pain relievers If you’re allergic, you can have a harmful reaction that affects your breathing, sinuses and skin.
