4 Conclusion and results:
Given the overall clinical picture, a presumptive diagnosis of Pneumocystis pneumonia was made, and the patient was initiated on therapy. Septran double strength, containing sulfamethoxazole (800 mg) and trimethoprim (160 mg), was started, and the patient tolerated the treatment well for a total of 21 days. After one week of treatment, the patient showed improvement in breathing and became afebrile. Follow-up chest X-rays also demonstrated signs of improvement, and eventually, the patient fully recovered.
