Rhinoscleroma: A Chronic Bacterial Infection

Rhinoscleroma, also known as scleroma, is a rare and chronic bacterial infection that primarily affects the upper respiratory tract, particularly the nasal cavity and nasopharynx. The disease is caused by the gram-negative bacillus Klebsiella rhinoscleromatis.

Characteristics of Rhinoscleroma

• A granulomatous disease characterized by the formation of firm, rubbery nodules in the affected areas [2][6]
• Can lead to airway obstruction and disfigurement if left untreated [14][15]
• Typically affects the nasal cavity and nasopharynx, but can also involve other parts of the respiratory tract such as the paranasal sinuses, mouth, lips, larynx, trachea, and bronchi [12]

Geographic Distribution

Rhinoscleroma is relatively rare in North America, but its causative bacteria are found in many other parts of the world. The disease is endemic in certain regions, including:

• Central and South America
• North and Central Africa
• Certain areas of Eastern Europe [15]

Symptoms and Diagnosis

The symptoms of rhinoscleroma can be nonspecific and may include:

• Ongoing nasal symptoms such as discharge, crusting, or bleeding
• Swelling or lumps in the nose or surrounding areas
• Difficulty breathing or swallowing

Early detection is essential for proper treatment of this disease [13].

Treatment and Prognosis

Rhinoscleroma can be challenging to treat due to its chronic course and need for prolonged therapy. Treatment typically involves antibiotics, surgery, or a combination of both. With prompt and appropriate treatment, the prognosis for recovery is generally good.

What is Rhinoscleroma? Rhinoscleroma, also known as scleroma, is a rare chronic granulomatous disease caused by the bacterium Klebsiella rhinoscleromatis. It primarily affects the nasal passages and sinuses, but can spread to other parts of the face and neck.

Common Signs and Symptoms:

• Nasal Obstruction: The most common symptom is difficulty breathing through the nose due to swelling and scarring in the nasal passages [1].
• Discharge and Crusting: Thick, yellowish or greenish discharge and crusting are often present in the nasal cavity [2].
• Facial Deformity: As the disease progresses, it can cause facial deformities, including a sunken appearance of the face, a prominent nose, and a drooping eyelid [3].
• Pain and Swelling: Pain and swelling in the affected area are common complaints [4].
• Loss of Smell: Some people may experience a loss of smell or taste due to damage to the olfactory nerves [5].

Other Possible Symptoms:

• Fever and Chills: In some cases, patients may experience fever and chills as part of the disease process [6].
• Swollen Lymph Nodes: Swollen lymph nodes in the neck can occur if the infection spreads to other parts of the body [7].

It's essential to note that these symptoms can be similar to those of other conditions, such as sinusitis or nasal polyps. A proper diagnosis by a healthcare professional is necessary for an accurate diagnosis and treatment plan.

Treatment Options for Rhinoscleroma

Rhinoscleroma, a chronic and progressive condition affecting the nasal passages and airways, can be effectively managed with long-term antibiotic treatment and surgery in some cases.

• Antibiotic Therapy: The primary treatment for rhinoscleroma involves prolonged antibiotic therapy using various medications such as:
  • Doxycycline
  • Ciprofloxacin
  • Ceforanide
  • Rifampicin
  • Streptomycin
  • Fluoroquinolone
• Surgical Intervention: In cases where complications such as airway obstruction occur, surgical debridement and correction of sclerotic defects may be necessary.
• Combination Therapy: Treatment for rhinoscleroma often involves a combination of medical care and surgical intervention to address granulomatous lesions or scarring stenosis.

Key Antibiotics Used in Rhinoscleroma Treatment

Some notable antibiotics used in the treatment of rhinoscleroma include:

• Ciprofloxacin, which has been shown to be effective against Klebsiella rhinoscleromatis [4][7]
• Rifampicin, which has been used systemically with success as a new antibiotic for the treatment of scleroma [6]
• Levofloxacin, rifampicin, and co-trimoxazole have also been used in combination to treat rhinoscleroma [8]

Importance of Continued Clinical Follow-up

Due to the high relapse rate associated with rhinoscleroma, continued clinical follow-up is essential to monitor the effectiveness of treatment and address any complications that may arise.

In some cases, surgical intervention may be necessary to address complications such as airway obstruction.

The differential diagnosis of rhinoscleroma includes:

1. Leprosy: A chronic bacterial infection caused by Mycobacterium leprae, which can affect the skin, nerves, and mucous membranes.
2. Sarcoidosis: An autoimmune disease characterized by the formation of granulomas in various organs, including the lungs, lymph nodes, and skin.
3. Tuberculosis: A bacterial infection caused by Mycobacterium tuberculosis, which can affect any part of the body, including the respiratory tract.
4. Fungal infections: Such as histoplasmosis, coccidioidomycosis, or blastomycosis, which can cause granulomatous inflammation in the lungs and other organs.
5. Sinonasal sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease): A rare condition characterized by the proliferation of histiocytes and lymphoid cells in the sinuses and lymph nodes.
6. Basal cell carcinoma: A type of skin cancer that can mimic rhinoscleroma in its appearance.
7. Actinomycosis: A bacterial infection caused by Actinomyces israelii, which can affect the face, neck, and upper respiratory tract.
8. Wegener's granulomatosis (Granulomatosis with Polyangiitis): A rare autoimmune disease characterized by the formation of granulomas in the lungs, kidneys, and other organs.

These conditions can be ruled out through a combination of clinical evaluation, imaging studies, laboratory tests, and histopathological examination of biopsy specimens.
