ICD-10: B37.1

Pulmonary candidiasis, classified under ICD-10 code B37.1, is a fungal infection of the lungs caused by the Candida species, most commonly Candida albicans. This condition is particularly significant in immunocompromised patients, such as those with HIV/AIDS, cancer, or those undergoing immunosuppressive therapy. Below is a detailed overview of pulmonary candidiasis, including its clinical description, symptoms, diagnosis, and treatment options.

Clinical Description

Etiology

Pulmonary candidiasis is primarily caused by the overgrowth of Candida species, which are normally present in small amounts in the human body, particularly in the mouth, throat, and gastrointestinal tract. Under certain conditions, such as a weakened immune system or prolonged antibiotic use, these fungi can proliferate and invade lung tissue, leading to infection[1][2].

Pathophysiology

The infection typically occurs when Candida enters the lungs through inhalation or hematogenous spread from other infected sites in the body. Once in the lungs, the fungi can cause inflammation and damage to lung tissue, leading to respiratory symptoms and complications[3].

Symptoms

Patients with pulmonary candidiasis may present with a variety of symptoms, which can range from mild to severe. Common symptoms include:

• Cough: Often persistent and may produce sputum.
• Fever: A common systemic response to infection.
• Chest pain: May occur due to pleuritic inflammation.
• Shortness of breath: Resulting from compromised lung function.
• Fatigue: General malaise and weakness are common in systemic infections[4][5].

Diagnosis

Clinical Evaluation

Diagnosis of pulmonary candidiasis typically involves a combination of clinical evaluation and laboratory tests. Key diagnostic steps include:

• Medical History and Physical Examination: Assessing risk factors such as immunosuppression, recent antibiotic use, and presenting symptoms.
• Imaging Studies: Chest X-rays or CT scans may reveal infiltrates or nodules indicative of fungal infection.
• Microbiological Testing: Sputum cultures, bronchoalveolar lavage (BAL), or lung biopsy can confirm the presence of Candida species. Histopathological examination may also be utilized to identify fungal elements in lung tissue[6][7].

Treatment

Antifungal Therapy

The primary treatment for pulmonary candidiasis involves antifungal medications. Commonly used agents include:

• Fluconazole: Often the first-line treatment for non-invasive candidiasis.
• Voriconazole: May be used for more severe cases or when resistance to fluconazole is suspected.
• Amphotericin B: Reserved for severe or resistant cases, particularly in immunocompromised patients[8][9].

Supportive Care

In addition to antifungal therapy, supportive care is crucial. This may include:

• Oxygen Therapy: To manage hypoxemia.
• Fluid Management: To maintain hydration and support overall health.
• Monitoring: Regular follow-up to assess treatment response and adjust therapy as needed[10].

Conclusion

Pulmonary candidiasis is a serious condition that requires prompt diagnosis and treatment, particularly in at-risk populations. Understanding its clinical presentation, diagnostic methods, and treatment options is essential for effective management. As the incidence of fungal infections continues to rise, especially among immunocompromised individuals, awareness and education about pulmonary candidiasis remain critical in clinical practice.
