[Case Report: Clindamycin with Primaquine Therapy for Severe Pneumocystis Pneumonia].

Abstract

A Japanese female in her 60's on 5 years' treatment with prednisolone 5 mg for ulcetarive colitis developed severe bloody stools and diarrhea and was admitted. A total colectomy was performed because leukocytapheresis with intravenous corticosteroid administration (prednisolone 70 mg/day) relieved her symptoms partially. Pneumocystis pneumonia (PCP) prophylaxis was not introduced then. She developed acute respiratory failure on postoperative day (POD) 8, and was intubated and moved to our intensive care unit. PCP was suspected and sulfamethoxazole/trimethoprim (ST) was started with methylprednisolone 40 mg/day. The pneumonia initially improved but got worse around POD 27 and pulse corticosteroid therapy was administered. Antibiotics were first changed to pentamidine and finally changed to clindamycin/primaquine because of adverse reactions due to both of the medications. She recovered fully and experienced no exacerbation after discontinuation of the secondary prophylaxis. This is the first report of primaquine administration for PCP in Japan. Clindamycin/primaquine are second-line drugs but very important because the first-line medications such as ST and pentamidine cause adverse reactions and frequently result in discontinuation, as was the case in our present patient. Nowadays immunosuppresive therapy for malingnancies and autoimmune diseases has been introduced more frequently than before, PCP has attracted more attention. Therefore primaquine should be approved for appropriate use without delay in Japan.
