[Rhodococcus equi infection in HIV disease]

Area of Science:

• Infectious Diseases
• Pulmonology
• Neurology

Background:

• Rhodococcus equi is an opportunistic pathogen causing severe infections in immunocompromised individuals, particularly those with HIV.
• Pneumonia, septicemia, and metastatic brain abscesses are potential complications of Rhodococcus equi infection.

Observation:

• A case of Rhodococcus equi pneumonia with septicemia and a metastatic brain abscess in an HIV-infected male is presented.
• Initial treatment with combined oral and parenteral antibiotics led to rapid improvement of cavitating pulmonary disease.
• Pulmonary relapse and brain abscess recurrence occurred after one month of initial treatment.

Findings:

• Subsequent outpatient therapy with ceftriaxone, ciprofloxacin, and cotrimoxazole resulted in clinical and radiological improvement within four weeks.
• The case highlights the challenges in managing disseminated Rhodococcus equi infections in HIV patients.
• Successful treatment required a multi-drug regimen and close monitoring.

Implications:

• Early consideration of surgical resection for localized Rhodococcus equi processes is crucial.
• Prolonged antibiotic therapy, potentially lasting several months, is recommended for complete eradication.
• This case underscores the importance of aggressive and tailored treatment strategies for opportunistic infections in immunocompromised populations.
