Interstitial Lung Disease
Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), is a group of respiratory diseases affecting the interstitium (the tissue and space around the alveoli (air sacs)) of the lungs. It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It may occur when an injury to the lungs triggers an abnormal healing response. Ordinarily, the body generates just the right amount of tissue to repair damage, but in interstitial lung disease, the repair process is disrupted, and the tissue around the air sacs (alveoli) becomes scarred and thickened. This makes it more difficult for oxygen to pass into the bloodstream. The disease presents itself with the following symptoms: shortness of breath, nonproductive coughing, fatigue, and weight loss, which tend to develop slowly, over several months. The average rate of survival for someone with this disease is between three and five years. The term I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Systemic Lupus Erythematosus
Lupus, technically known as systemic lupus erythematosus (SLE), is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissue in many parts of the body. Symptoms vary among people and may be mild to severe. Common symptoms include painful and swollen joints, fever, chest pain, hair loss, mouth ulcers, swollen lymph nodes, feeling tired, and a red rash which is most commonly on the face. Often there are periods of illness, called flares, and periods of remission during which there are few symptoms. The cause of SLE is not clear. It is thought to involve a mixture of genetics combined with environmental factors. Among identical twins, if one is affected there is a 24% chance the other one will also develop the disease. Female sex hormones, sunlight, smoking, vitamin D deficiency, and certain infections are also believed to increase a person's risk. The mechanism involves an immune response by autoantibodies against a person's own tiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects synovial joint, joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body. The disease may also affect other parts of the body, including skin, eyes, lungs, heart, nerves and blood. This may result in a anemia, low red blood cell count, pleurisy, inflammation around the lungs, and pericarditis, inflammation around the heart. Fever and low energy may also be present. Often, symptoms come on gradually over weeks to months. While the cause of rheumatoid arthritis is not clear, it is believed to involve a combination of genetics, genetic and environmental factors. The underlying mechanism involves the body's immune system attacking the joints. This results in inflammation and thickening of the synovium, joint capsule. It also affec ...

Sarcoidosis
Sarcoidosis (also known as ''Besnier-Boeck-Schaumann disease'') is a disease involving abnormal collections of inflammatory cells that form lumps known as granulomata. The disease usually begins in the lungs, skin, or lymph nodes. Less commonly affected are the eyes, liver, heart, and brain. Any Organ (anatomy), organ can be affected though. The signs and symptoms depend on the organ involved. Often, no, or only mild, symptoms are seen. When it affects the lungs, wheezing, coughing, shortness of breath, or chest pain may occur. Some may have Löfgren syndrome with fever, large lymph nodes, arthritis, and a rash known as erythema nodosum. The cause of sarcoidosis is unknown. Some believe it may be due to an immune reaction to a trigger such as an infection or chemicals in those who are genetically predisposed. Those with affected family members are at greater risk. Diagnosis is partly based on signs and symptoms, which may be supported by tissue biopsy, biopsy. Findings that make i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autoimmune Diseases
An autoimmune disease is a condition arising from an abnormal immune response to a functioning body part. At least 80 types of autoimmune diseases have been identified, with some evidence suggesting that there may be more than 100 types. Nearly any body part can be involved. Common symptoms can be diverse and transient, ranging from mild to severe, and generally include low grade fever and feeling tired. The cause is unknown. Some autoimmune diseases such as lupus run in families, and certain cases may be triggered by infections or other environmental factors. Some common diseases that are generally considered autoimmune include celiac disease, diabetes mellitus type 1, graves' disease, inflammatory bowel disease, multiple sclerosis, alopecia areata, addison’s disease, pernicious anemia, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus. The diagnosis can be difficult to determine. Treatment depends on the type and severity of the condition. Nonsteroidal a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lymphoid Interstitial Pneumonia
Lymphocytic interstitial pneumonia (LIP) is a syndrome secondary to autoimmune and other lymphoproliferative disorders. Symptoms include fever, cough, and shortness of breath. Lymphocytic interstitial pneumonia applies to disorders associated with both monoclonal or polyclonal gammopathy. Signs and symptoms Patients with lymphocytic interstitial pneumonia may present with lymphadenopathy, enlarged liver, enlarged spleen, enlarged salivary gland, thickening and widening of the extremities of the fingers and toes ( clubbing), and breathing symptoms such as shortness of breath and wheezing. Causes Possible causes of lymphocytic interstitial pneumonia include the Epstein–Barr virus, auto-immune, and HIV. Diagnosis Arterial blood gases may reveal signs of hypoxemia when tested in a lab. Respiratory alkalosis Respiratory alkalosis is a medical condition in which increased respiration elevates the blood pH beyond the normal range (7.35–7.45) with a concurrent reducti ...

Cryptogenic Organizing Pneumonia
Cryptogenic organizing pneumonia (COP), formerly known as bronchiolitis obliterans organizing pneumonia (BOOP), is an inflammation of the bronchioles ( bronchiolitis) and surrounding tissue in the lungs. It is a form of idiopathic interstitial pneumonia. It is often a complication of an existing chronic inflammatory disease such as rheumatoid arthritis, dermatomyositis, or it can be a side effect of certain medications such as amiodarone. COP was first described by Gary Epler in 1985. The clinical features and radiological imaging resemble infectious pneumonia. However, diagnosis is suspected after there is no response to multiple antibiotics, and blood and sputum cultures are negative for organisms. Terminology "Organizing" refers to unresolved pneumonia (in which the alveolar exudate persists and eventually undergoes fibrosis) in which fibrous tissue forms in the alveoli. The phase of resolution and/or remodeling following bacterial infections is commonly referred to as or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Respiratory Bronchiolitis-associated Interstitial Lung Disease
Respiratory bronchiolitis is a lung disease associated with tobacco smoking. Topic Completed: 1 July 2020. Minor changes: 1 July 2020 In pathology, it is defined by the presence of " smoker's macrophages". When manifesting significant clinical symptoms it is referred to as respiratory bronchiolitis interstitial lung disease (RB-ILD). Diagnosis Diagnosis of respiratory bronchiolitis requires a correlation of clinical, radiologic and pathologic findings: *Clinical: Symptoms and pulmonary function testing *Radiologic: Chest radiograph and high-resolution computed tomography * Pathologic: Lung biopsy with "smoker's macrophages" limited to distal airspaces and peribronchiolar airspaces, and minimal to absent peribronchiolar interstitial fibrotic thickening Respiratory bronchiolitis interstitial lung disease ''Respiratory bronchiolitis interstitial lung disease'' is respiratory bronchiolitis that manifests as a clinically significant interstitial lung disease. It is a form of idi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonspecific Interstitial Pneumonia
Non-specific interstitial pneumonia (NSIP) is a form of idiopathic interstitial pneumonia. Symptoms Symptoms include cough, difficulty breathing, and fatigue. Causes It has been suggested that idiopathic nonspecific interstitial pneumonia has an autoimmune mechanism, and is a possible complication of undifferentiated connective tissue disease; however, not enough research has been done at this time to find a cause. Patients with NSIP will often have other unrelated lung diseases like COPD or emphysema, along with other auto-immune disorders. Diagnosis A full clinical diagnosis can only be made from a lung biopsy of the tissue, fully best performed by a VATS, done by a cardio-thoracic surgeon. Some pulmonologists may first attempt a bronchoscopy; however, this frequently fails to give a full or correct diagnosis. Lung biopsies performed on patients with NSIP reveal two different disease patterns – cellular and fibrosing – which are associated with different prognoses. ...

Acute Interstitial Pneumonia
Acute interstitial pneumonitis is a rare, severe lung disease that usually affects otherwise healthy individuals. There is no known cause or cure. Acute interstitial pneumonitis is often categorized as both an interstitial lung disease and a form of acute respiratory distress syndrome (ARDS) but it is distinguished from the ''chronic'' forms of interstitial pneumonia such as idiopathic pulmonary fibrosis. Symptoms and signs The most common symptoms of acute interstitial pneumonitis are highly productive cough with expectoration of thick mucus, fever, and difficulties breathing. These often occur over a period of one to two weeks before medical attention is sought. The presence of fluid means the person experiences a feeling similar to 'drowning'. Difficulties breathing can quickly progress to an inability to breathe without support (respiratory failure). Acute interstitial pneumonitis typically progresses rapidly, with hospitalization and mechanical ventilation often required o ...
