ICD-10: A32.81

Oculoglandular listeriosis, classified under ICD-10 code A32.81, is a rare form of listeriosis that primarily affects the eyes and associated lymphatic tissues. This condition is caused by the bacterium Listeria monocytogenes, which can lead to serious infections, particularly in vulnerable populations such as pregnant women, newborns, the elderly, and individuals with compromised immune systems.

Clinical Description

Pathophysiology

Oculoglandular listeriosis occurs when Listeria monocytogenes enters the body, often through the conjunctiva of the eye. This can happen via direct contact with contaminated materials, such as food or infected animals. Once the bacteria invade, they can cause inflammation and infection in the eye (conjunctivitis) and the regional lymph nodes, leading to symptoms that can significantly impact vision and overall health.

Symptoms

The clinical presentation of oculoglandular listeriosis typically includes:
- Conjunctivitis: Inflammation of the conjunctiva, leading to redness, swelling, and discharge.
- Lymphadenopathy: Swelling of the lymph nodes, particularly those near the affected eye, which may become tender.
- Ocular Pain: Patients may experience discomfort or pain in the affected eye.
- Visual Disturbances: In some cases, there may be blurred vision or other visual impairments.

Diagnosis

Diagnosis of oculoglandular listeriosis is primarily clinical, supported by laboratory tests. Key diagnostic steps include:
- History and Physical Examination: A thorough history of exposure to potential sources of Listeria, such as unpasteurized dairy products or contaminated food, is essential.
- Microbiological Testing: Isolation of Listeria monocytogenes from conjunctival swabs or lymph node aspirates can confirm the diagnosis.
- Serological Tests: These may be used to detect antibodies against Listeria.

Treatment

Treatment for oculoglandular listeriosis typically involves:
- Antibiotic Therapy: The first-line treatment is usually with antibiotics such as ampicillin or penicillin. In cases of severe infection or in patients with penicillin allergies, alternatives like trimethoprim-sulfamethoxazole may be considered.
- Supportive Care: This may include topical treatments for conjunctivitis and management of symptoms.

Epidemiology

Oculoglandular listeriosis is uncommon, with most cases reported in individuals with direct exposure to infected animals or contaminated food products. The incidence is higher in immunocompromised individuals, making awareness and preventive measures crucial in at-risk populations.

Conclusion

Oculoglandular listeriosis, while rare, poses significant health risks, particularly for vulnerable groups. Early recognition and appropriate antibiotic treatment are essential for effective management. Awareness of the condition and its symptoms can aid in prompt diagnosis and reduce the risk of complications associated with this infection. For further information, healthcare providers should refer to clinical guidelines and resources on listeriosis management and prevention.
