Introduction

Granulomatosis is a type of granulomatosis that occurs when GPA, formerly known as Wegener's granulomatosis, is a necrotizing vasculitis of tiny vessels characterised by diffuse vascular wall inflammation with peri- and extravascular granulomatosis. GPA, in its complete/systemic form, links ENT, pulmonary, and renal involvement to necrotizing glomerulonephritis, which is the disease's key prognostic factor. This angiitis can affect any other organ (kidneys, peripheral nerves, eyes, skin, joints, and abdomen). Although many of the mechanisms involved are now better recognised, the pathophysiology of GPA is still unknown. The Cytoplasmic ANCA (C-ANCAs) auto antibodies, which target Proteinase 3 (PR3), a proteolytic enzyme found in the cytoplasmic granules of neutrophils and monocytes, are the primary players. In a genetically susceptible person, some viral and/or toxic substances may function as pathogenic factors, triggering vasculitis. Trauma was only sometimes mentioned as a possible cause of this systemic angiitis. We're reporting on an unusual case of fulminant and deadly GPA brought on by chest trauma [1].

Description

Signs & symptoms

Symptoms include mucous membrane ulcerations in the nose with secondary bacterial infection, a persistent runny nose, sinus pain, and a chronic middle ear infection (otitis media), which can cause hearing loss. Renal problems in some people can lead to kidney failure, a dangerous complication that necessitates dialysis or a kidney transplant. Coughing, coughing up blood (hemoptysis), and inflammation of the thin membrane lining the outside of the lungs and the tissues inside the lungs may be present if the lungs are afflicted. Other signs and symptoms may appear depending on which organ systems are damaged [2].

Granulomatosis with polyangiitis isn't a hereditary condition. It's considered an autoimmune disease. When the immune system of the body mistakenly targets healthy tissue, autoimmune diseases develop. Cigarette smoking is one of the environmental, infectious, and genetic variables that may play a role in the development of the illness. The illness can strike anyone at any age, but it is most common in those between the ages of 40 and 60. Wegener's granulomatosis or Wegener granulomatosis was the name given to granulomatosis with polyangiitis for many years. Wegener is the surname of a doctor who, in the 1930s, was one of the first to describe the condition in depth in medical literature. Before Wegener, the condition had been described by other doctors. Granulomatosis with polyangiitis is classified as a form of vasculitis, and further classified as a form of antineutrophil cytoplasmic antibodies-associated (ANCA-associated) vasculitis or ANCA-associated vasculitides (AAV).

The respiratory tract and kidneys are affected in the majority of patients. Some people may experience just minor symptoms, while others may experience life-threatening problems. The disease might develop slowly over several months or suddenly over a few days (acute). Because every person with granulomatosis with polyangiitis is different, the symptoms listed below may or may not apply to you. Fever, a general sensation of bad health (malaise), weakness and weariness, joint discomfort (arthralgia), loss of appetite, and unexpected weight loss are all possible early symptoms. Sometimes, granulomatosis with polyangiitis affects just the upper airways and the rest of the body is unaffected for years before other symptoms appear, and sometimes, granulomatosis with polyangiitis affects only the upper airways and the rest of the body is unaffected. This is known as restricted or localised granulomatosis with polyangiitis [3].

Many people who are afflicted will suffer lung problems (pulmonary). A persistent cough, blood in the cough (hemoptysis), difficulty breathing (dyspnea), chest pain, inflammation of the thin membrane lining the outside of the lungs and the inside of the lungs (pleuritis), excess fluid buildup around the lungs (pleural effusion), and inflammation of the lung tissues themselves are some of the symptoms. On X-ray inspection, substances such as blood, pus, or protein (pulmonary infiltrates) may be found in lung tissue. Subglottic stenosis is a condition in which the portion of the windpipe below the voice cords (subglottis) becomes inflamed and narrowed. Inflammation and narrowing of the entire windpipe (tracheal stenosis) are potentially possible side effects. Breathing difficulties, high-pitched noisy breathing (stridor), wheezing, and voice changes are all symptoms of these disorders. Lung bleeding (haemorrhage) is a significant consequence that necessitates hospitalisation and intensive treatment. In youngsters with this condition, respiratory problems are frequently the initial symptom.

Approximately 75% of people will acquire kidney (renal) disease at some point in their lives. Many people, however, show no signs or symptoms (asymptomatic). High blood pressure (hypertension) and fluid retention in the legs are possible side effects for those who are affected. Inflammation of the glomeruli, a clump of blood arteries and nerve fibres in the kidney that filter the blood, causes these symptoms. Glomerulonephritis is a disorder in which the glomeruli grow enlarged and malformed and are unable to fulfil their normal functions. This can result in a modest amount of blood in the urine but a large amount of protein loss. If left untreated, kidney disease can worsen, eventually leading to life-threatening kidney (renal) failure.

Diagnosis

A thorough clinical evaluation, including routine laboratory testing, a full patient history, identification of pertinent symptoms, and a number of specialised diagnostics, is used to diagnose granulomatosis with polyangiitis. Surgical removal (biopsy) and microscopic analysis of small samples of tissue from an afflicted organ can reveal vasculitis or granulomas in many persons. Obtaining a biopsy sample from the upper respiratory tract may be the first step for doctors. However, there are situations when there isn't enough tissue to make a clear diagnosis. A biopsy of the lung or kidney tissue may be performed. The greatest results may come from a lung biopsy [4].

Blood testing, in addition to biopsy, may be used to rule out other illnesses. A blood test may also identify the existence of antineutrophil cytoplasmic antibody, which is a specific form of antibody (ANCA). X-rays and other specialist imaging tests can also help confirm a granulomatosis with polyangiitis diagnosis. X-rays of the lungs or sinuses can identify symptoms associated with the issue (such as thickening of the sinus lining), rule out other conditions, and reveal the extent of the problem.

Treatment

The therapy of granulomatosis with polyangiitis is focused on the specific symptoms that each patient experiences. Patients with granulomatosis with polyangiitis have a longer life expectancy and less organ damage thanks to modern treatment. Treatment may necessitate the collaboration of a group of professionals. Specific therapy techniques and interventions may differ depending on a variety of circumstances, including the presence or absence of specific symptoms, the organs affected, the overall severity of the condition, the individual's age and general health, and/or other considerations [5].

Conclusion

Physicians and other members of the health care team should make decisions about the use of specific drug regimens and/or other treatments based on the specifics of the patient's case; a thorough discussion of the potential benefits and risks, including possible side effects and long-term effects; patient preference; and other appropriate factors.
