Follow-up and Outcomes
After two weeks of treatment with doxycycline plus rifampin, clinically, the patient recovered with no difficulty in breathing and no chest pain. The results of the follow-up serology for B. henselae IgG were 1:512. The patient was discharged from the hospital approximately four weeks after admission, with a recommendation to visit a cardiologist, stop his IV drug abuse, and continue doxycycline and enoxaparin. A controlled chest X-ray showed improvement, and the chest tube was discontinued. The patient left the hospital in good general condition, without fever, with a normal heart rate and acceptable SpO2 (>94%).
