C-ANCA and p-ANCA are tests for the diagnosis of rheumatological diseases. They are also used in evaluation. These conditions are usually caused by a dysfunction in the immune system that triggers an attack on certain tissues that the body perceives as foreign or invading microorganisms or poisons. These autoimmune conditions can be debilitating and cause significant health complications and disability. In particular, c-ANCA and p-ANCA tests help diagnose conditions that cause vasculitis.

ANCA stands for antineutrophil cytoplasmic antibodies 1 according to Lab Tests Online. These antibodies are accidentally produced by the body to attack its own neutrophils, which are white blood cells that help fight bacterial infections. When viewed under the microscope after staining, c-ANCA tests show the presence of these antibodies in the cytoplasm, the internal microscopic compound that holds neutrophil 1 cells together. The p-ANCA test shows the presence of antineutrophil antibodies around the nucleus. P-ANCA and c-ANCA cells are often seen in conditions such as Wegener’s granulomatosis and other vasculitides. The symptoms of vasculitides differ depending on the vessels and organs affected.

According to the National Institute of Allergy and Infectious Diseases, Wegener’s granulomatosis usually affects the lungs and kidneys 3. symptoms include sinus pain, bloody fluid from the nose, nasal ulcers, and upper respiratory tract infection symptoms that do not go away with proper treatment. Cough, shortness of breath, and bloody sputum may also occur if the lungs are affected. Kidney involvement usually does not cause noticeable symptoms, but can cause long-term damage. Microscopic polyangitis, another vasculitis detected by ANCA tests, causes kidney inflammation, weight loss, skin lesions, and nerve damage. Treatment of vasculitides often requires a multidisciplinary approach to dealing with the multiple organs affected. Medications include steroids to reduce the inflammation surrounding the blood vessels and immunosuppressants, including drugs such as azathioprine and cyclophosphamide, which aim to control the body’s autoimmune reaction while protecting the patient from the side effects of steroids.

Other drugs include drugs that prevent steroid-induced bone loss and antibiotics that prevent pneumonia. According to the American Association of Family Physicians, night sweats accompanied by severe, unexplained weight loss are bothersome symptoms that may indicate a serious disorder. The cause may be an infectious disease, a hormonal disorder, or some cancers. People who experience night sweats accompanied by severe weight loss should seek medical evaluation as soon as possible.

HIV/AIDS is an infectious disease that damages immune system cells and renders the patient unable to fight infections. The HIV virus is found in blood, semen, and vaginal fluid and is most commonly spread through unprotected sex or shared needles and syringes. The early stage of HIV can cause short-term flu-like symptoms, followed by up to 10 years of symptom-free years. In the more advanced stage, drenching night sweats and severe, unexplained weight loss are common. According to the National Institutes of Allergy and Infectious Diseases, patients may also experience fever, severe fatigue, swollen lymph nodes, diarrhea, memory loss, and patches of red or purplish skin.

Tendinosis is a disease that affects the tendons. According to the AAFP, tendinitis is often confused with tendinosis, a degenerative condition with chronic symptoms. The AAFP notes that acute inflammatory tendinopathies do exist, but most patients seen and treated by doctors for chronic tendon problems will have tendinosis, not tendinitis. Tendinosis can result from small tears in or around the connective tissue of the tendon that cause upregulation of tendon repair cells. Connective tissue tears can result in decreased tendon tensile strength, which increases the likelihood of tendon rupture. The AAFP notes that about 80 percent of patients with overuse tendinopathy fully recover within three to six months, and common treatment modalities for tendinosis include ultrasound, shock wave therapy, massage, and activity modification.

Tuberculosis

Tuberculosis or TB is a serious infectious disease that primarily affects the lungs but can affect any organ in the body. It is spread through airborne droplets when an infected person speaks or coughs. Typically, it takes close and prolonged contact with an infected person to spread the disease, MayoClinic.com says. Night sweats, unexplained weight loss, fever and chills are common symptoms. A cough and chest pain that produces thick, sometimes bloody mucus, typically occurs when tuberculosis affects the lungs. Other symptoms depend on the organ affected, such as back pain when tuberculosis occurs in the spine.

Hodgkins lymphoma is cancer of cells in the immune system called lymphocytes. The National Cancer Institute says Hodgkins lymphoma symptoms often include enlarged lymph nodes in the neck, armpits, or groin, drenching night sweats, and unexplained weight loss. Fever, itchy skin, pain in the lymph nodes after drinking alcohol, cough and fatigue are also typical. Cancerous cells can spread and invade other organs in the body, such as the liver, bones, lungs, and bone marrow. Treatment depends on the stage or extent of the disease when diagnosed. Treatments may include chemotherapy, radiation, and stem cell transplant.

Various diseases can affect the tendons. According to the American Academy of Family Physicians, or AAFP, the correct diagnosis of a tendon-related problem requires a healthcare provider to evaluate the cause of the patient’s pain or discomfort and the anatomy of the involved area and perform appropriate orthopedic tests. and other physical examination maneuvers While traumatic tendon injuries are relatively common, diseases can also affect the tendons, causing severe pain.
