I – Introduction:
A- Definition of Sarcoidosis:
Sarcoidosis is a chronic autoimmune disease that can affect different organs and tissues in the body, including the skin, lungs, lymph nodes, heart and bones. It is characterized by the formation of granulomas, which are accumulations of immune cells called macrophages. The exact cause of Sarcoidosis is still largely unknown, but certain factors such as genetics, infections and environmental factors may play a role. Symptoms of Sarcoidosis can vary greatly from person to person and depend on the organ or tissue affected. The most common symptoms include fatigue, weight loss, fever, cough, and chest pain. The diagnosis of Sarcoidosis is based on a complete clinical examination, laboratory tests and imaging, as well as on the assessment of the patient’s symptoms and medical history. Sarcoidosis treatment can include medications, non-drug therapies, and surgical treatments for serious complications.
B- Incidence and prevalence of the disease:The incidence of Sarcoidosis is difficult to determine with precision due to the variability of symptoms and the difficulty of its diagnosis. However, it is estimated that the disease affects between 1 to 10 people per 100,000 inhabitants in industrialized countries. The prevalence of Sarcoidosis also varies between populations, with a greater frequency observed in males and black people. Sarcoidosis can occur at any age, but is most common in people between the ages of 30 and 50. The disease can affect all populations, but some studies have shown a higher incidence in high-risk populations, such as the military, chemical-exposed workers, and people with a family history of the disease.

II- Etiology and pathogenesis:
A- Risk factors:
The risk factors for Sarcoidosis are still poorly understood, but several factors appear to increase the risk of developing the disease. First, genetics plays an important role, as people with a family history of Sarcoidosis are at higher risk of developing the disease. Additionally, people with other autoimmune diseases, such as lupus or rheumatoid arthritis, are also at higher risk of developing sarcoidosis.
Exposure to certain chemicals, such as industrial solvents, can also increase the risk of developing Sarcoidosis. Likewise, people with occupational exposure to chemicals, such as construction workers or workers in the chemical industry, are at greater risk. Finally, black race and male gender are also considered risk factors for Sarcoidosis.
It is important to understand the risk factors for Sarcoidosis as this can help identify people at high risk of developing the disease. This information can also help healthcare professionals better monitor those at risk, which can help in early diagnosis and more effective treatment. Finally, understanding risk factors can also help develop prevention strategies to reduce the risk of developing Sarcoidosis.
B- Mechanisms of development of the disease:
The development of Sarcoidosis is mainly due to an abnormal autoimmune response of the immune system. In Sarcoidosis, the immune system attacks healthy body tissues, which can lead to inflammation and damage to internal organs. This mechanism can be triggered by several factors, such as antigens present in healthy cells or environmental factors such as chemicals or infections.
The inflammation can spread to multiple organs, such as the lungs, skin, bones, and eyes, and can lead to damage to these organs. However, the exact mechanism by which Sarcoidosis develops and spreads through organs is not yet fully understood.
It is important to understand the mechanisms of development of Sarcoidosis as it can help to better understand the disease and to develop new approaches for treatment. Ongoing research into the developmental mechanisms of Sarcoidosis may also lead to a deeper understanding of the underlying causes of the disease, which may contribute to more effective prevention and more targeted treatment.
C- Relationship between Sarcoidosis and other diseases:
Sarcoidosis can be associated with other autoimmune and non-autoimmune diseases. For example, people with Sarcoidosis can also suffer from diseases such as lupus, rheumatoid arthritis or celiac disease. Additionally, people with Sarcoidosis may also be at risk of developing other conditions such as heart disease, diabetes, or cancer.
It is important to understand the relationships between Sarcoidosis and other diseases to better understand how the disease works and its consequences on overall health. It can also help healthcare professionals assess the risks for people with sarcoidosis, which can lead to closer monitoring and more targeted treatment. Finally, understanding the relationships between Sarcoidosis and other diseases can also help develop strategies to prevent other health problems associated with Sarcoidosis.
III- Symptoms and clinical signs:
A- General presentation:
Sarcoidosis is a systemic autoimmune disease, which means it can affect many different organs and systems in the body. This disease can cause pain, fatigue, and serious health problems if not treated properly. Sarcoidosis can affect the lungs, heart, skin, bones, eyes and other organs, and can lead to serious complications such as pulmonary fibrosis, cardiomyopathy and loss of vision.
Symptoms of Sarcoidosis can vary greatly from person to person and can often be confused with those of other illnesses. Additionally, Sarcoidosis can be difficult to diagnose, as symptoms may be mild or absent at the onset of the disease. Therefore, it is important to see a doctor if you think you might have Sarcoidosis, in order to get a prompt diagnosis and proper treatment.
In general, Sarcoidosis is a complex disease that can cause serious health problems, but it can be treated effectively with medication, therapy and regular medical monitoring. People with Sarcoidosis can live normal, productive lives with proper treatment and working closely with their doctor.

Symptoms of Sarcoidosis can vary greatly from person to person and can often be confused with those of other illnesses. However, some of the most common symptoms associated with Sarcoidosis include fatigue, fever, weight loss, joint pain, cough and dyspnea.
Additionally, Sarcoidosis can affect the skin, causing painful skin lumps, and can also cause vision problems, such as conjunctivitis and scleritis. Other symptoms include digestive issues, such as diarrhea and abdominal pain, and thyroid issues, such as hypothyroidism or hyperthyroidism.
It is important to note that most people with Sarcoidosis do not have all of the symptoms, and the severity and frequency of symptoms can vary greatly from person to person. Therefore, it is important to see a doctor if you think you might have Sarcoidosis, in order to get a prompt diagnosis and proper treatment.
C- Evolution of the disease and potential complications:
The course of Sarcoidosis can vary greatly from person to person, ranging from mild illness to severe and disabling illness. Some people may have mild symptoms that do not require treatment, while others may develop serious complications such as lung, heart, or kidney damage.
Lung damage can lead to pulmonary fibrosis, respiratory failure and an increased risk of pneumonia. Heart damage can lead to heart failure, endocarditis, and embolism. Kidney damage can lead to kidney failure, which may require dialysis or a kidney transplant.
It is also possible for Sarcoidosis to affect other organs, such as the central nervous system, eyes, liver and bones. The disease can also lead to psychological problems, such as depression and anxiety. Therefore, it is important to regularly monitor the symptoms of Sarcoidosis and seek medical attention if you think you may be developing complications.
A- Anamnesis and clinical examination:
The history and clinical examination are key elements for the diagnosis of Sarcoidosis. During the history, the doctor will ask about the patient’s medical history, including any symptoms present, family history of autoimmune diseases, potential occupational exposures, and known risk factors.
The clinical examination consists of a physical evaluation of the patient by a doctor, who will look for signs of the disease, such as skin lumps, breathing problems, vision problems and thyroid problems. The doctor may also perform laboratory tests to assess the function of different organs, such as the lungs, heart, and kidneys.
Imaging can also be used to help diagnose Sarcoidosis, including chest X-rays, chest and abdominal CT scans, and imaging tests of the thyroid and eyes. Finally, it may be necessary to perform a biopsy to obtain a definitive diagnosis.
In summary, the history and physical examination are important steps in the diagnosis of Sarcoidosis, and can help identify symptoms and potential complications of the disease.
B- Laboratory and imaging tests:
Laboratory and imaging tests are key tools for the diagnosis of sarcoidosis. Laboratory tests, such as blood and urine tests, can help detect abnormalities and markers of disease. For example, an increase in ESR (erythrocyte sedimentation rate) or CRP (C-reactive protein) can indicate inflammation in the body. Also, specific tests such as antinuclear antibodies can help confirm the diagnosis of sarcoidosis. Imaging tests, such as X-rays, computed tomography (CT) scans, and MRIs (magnetic resonance imaging), can show damage caused by sarcoidosis to internal organs, such as the lungs and heart. The results of these tests often help doctors make an accurate diagnosis and develop an effective treatment plan for patients with sarcoidosis. Finally, these tests can also be used to monitor disease progression and treatment effects.
C- Assessment of the severity of the disease:
Assessment of disease severity is important in determining the appropriate treatment for patients with sarcoidosis. There are different tools to assess disease severity, such as sarcoidosis severity scores and World Health Organization (WHO) classifications. These tools take into account factors such as the location of the lesions, the progression of the disease and the symptoms presented by the patient. Doctors may also use laboratory and imaging tests to assess the severity of the disease, such as measuring levels of inflammation in the blood and observing damage to internal organs. Assessing disease severity is important because it helps doctors determine the level of treatment needed to control the disease and prevent serious complications. Additionally, it can also help determine palliative care and support needs for critically ill sarcoidosis patients.
A- Drug therapies:
Drug therapies are a key part of treating sarcoidosis. There are several classes of drugs used to control symptoms and slow disease progression, such as corticosteroids, immunosuppressants, and targeted biotherapies. Corticosteroids are often the first choice for treating sarcoidosis because they can quickly reduce inflammation and relieve symptoms. However, they can also cause significant side effects, such as weight gain and brittle bones. Immunosuppressants, such as azathioprine and methotrexate, can be used to control the abnormal immune response that causes sarcoidosis. Finally, targeted biotherapies, such as TNF inhibitors, may help control inflammation by targeting molecules involved in the immune response. The choice of drug therapy will depend on the severity of the disease, the symptoms presented by the patient and the response to previous treatments. It is important to discuss with your doctor to determine the most appropriate treatment for each case of sarcoidosis.
B- Non-drug therapies:
Non-drug therapies can play an important role in the treatment of sarcoidosis. Patients may benefit from measures such as physiotherapy to improve respiratory and muscle function, as well as physiotherapy to strengthen muscles weakened by the disease. Physical therapy can also help prevent blood clots from forming and improve blood circulation. Exercise therapy may also be beneficial for improving overall fitness, building muscle, and maintaining a healthy weight. Occupant therapy can also help manage the psychological effects of sarcoidosis, such as stress, anxiety, and depression. Finally, stress management strategies, such as meditation, deep breathing and relaxation can be helpful in helping patients manage pain and other symptoms of the disease. It is important to discuss with your doctor to determine the most appropriate non-drug therapies for each case of sarcoidosis.
C- Evaluation of the effectiveness of the treatment:
Assessing treatment efficacy is an important aspect of monitoring patients with sarcoidosis. This may involve regularly monitoring symptoms, performing laboratory tests to monitor the function of affected organs, and performing imaging tests to assess disease progression. Doctors can also use severity scales such as the International Working Group’s sarcoidosis classification to assess disease severity and monitor response to treatment. Response to treatment can vary greatly from patient to patient, depending on the severity of the disease, the symptoms exhibited, and the response to previous treatments.
A- Measures to reduce the risk of developing Sarcoidosis:
Although there is no sure way to completely prevent sarcoidosis, certain risk factors can be minimized to reduce the risk of developing the disease. First, people with a family history of sarcoidosis may be at higher risk of developing the disease and may benefit from regular monitoring by a doctor. Additionally, people exposed to potentially harmful substances, such as industrial chemicals, airborne particles, and ionizing radiation, can minimize their exposure to reduce their risk of sarcoidosis.
