Abstract

Nocardiosis is a rare disease generally caused by members of Nocardia asteroides complex, particularly in immunosupressed patients. Nocardia cyriacigeorgica is a newly described member of this complex. In this article, a case of pulmonary nocardiosis with a large solitary cavitary nodule caused by N. cyriacigeorgica, in a patient receiving corticosteroid therapy was presented. A 29 years old male patient receiving prednisolone for 5 months was admitted to our hospital with fever, cough, right thoracic pain and night sweats. Computed tomography scan of chest demonstrated a large solitary cavitary nodule in the right lower lobe. Gram stained smear of the sputum revealed gram-positive, beaded, branched filamentous bacilli. On the third day of his admission, a catalase positive, oxidase negative and immotile bacilli, compatible with Nocardia spp., were isolated from the sputum sample taken at the day of admission. The isolated bacterium was identified as N. cyriacigeorgica by reference laboratory (Lyon, France). Oral trimethoprim (320 mg/day) and sulfamethoxazole (1600 mg/day) therapy given for three months, resulted in complete cure of the lesion without any sequela. This was the fourth case of pulmonary nocardiosis caused by N. cyriacigeorgica reported from Turkey. Microbiological examination of sputum is the most important tool for the diagnosis. Treatment with appropriate antibiotics may achieve complete cure even in large cavitary lesions. In conclusion, pulmonary nocardiosis should be considered in differential diagnosis of solitary cavitary nodules, especially in immunocompromised patients.

Özet

Nokardiyoz, genellikle Nocardia asteroides kompleks üyelerinin, bağışıklık sistemi baskılanmış insanlarda oluşturduğu nadir bir hastalıktır. Nocardia cyriacigeorgica bu kompleksin yeni tanımlanan bir üyesidir. Bu makalede kortikosteroid tedavisi almakta olan bir hastada N. cyriacigeorgica'nın etken olarak izole edildiği kavitasyon gösteren büyük soliter akciğer lezyonu şeklinde ortaya çıkan bir pulmoner nokardiyoz olgusu sunulmaktadır. Prednizolon tedavisi almakta olan 29 yaşında erkek hasta, ateş, öksürük, sağ yan ağrısı ve gece terlemesi yakınmalarıyla kliniğimize başvurmuştur. Toraks bilgisayarlı tomografisinde, sağ akciğer alt lob yerleşimli büyük, soliter, kaviter görüntü saptanan hastadan alınan balgam örneklerinin direkt mikroskobik incelemesinde gram-pozitif boyanan, teşbih tanesi şeklinde dizilimli, dallı-filamentöz basillere rastlanmıştır. Hastadan başvuru günü alınan balgam kültüründe, üçüncü gün Nocardia spp. olarak değerlendirilen, katalaz pozitif, oksidaz negatif ve hareketsiz basiller izole edilmiştir. Kesin tanı amacıyla referans laboratuvara (Lyon, Fransa) gönderilen bakteri, N. cyriacigeorgica olarak tiplendirilmiştir. Antibiyogram sonucuna göre oral uygulanan üç aylık trimetoprim (320 mg/gün)sülfametoksazol (1600 mg/gün) tedavisi ile lezyonun sekel bırakmadan tam olarak iyileştiği kaydedilmiştir. Bu olgu, bu bakterinin neden olduğu ülkemizden bildirilen N. cyriacigeorgica'ya bağlı dördüncü pulmoner nokardiyoz olgusudur. Balgam örneğinin mikrobiyolojik incelemesi, tanı için en önemli yöntemdir. Uygun antibiyotik tedavisi ile büyük kaviter lezyonlar bile sekel bırakmadan iyileşebilmektedir. Sonuç olarak, pulmoner nokardiyoz, radyolojik incelemelerde saptanan soliter, kaviter nodüllerin ayırıcı tanısında, özellikle de altta yatan hastalığı olan ya da immünsüpresif hastalarda mutlaka düşünülmelidir.
