Nocardia abscessus brain abscess in an immunocompetent host

Nocardia brain abscesses typically occur in immunocompromised patients. Most cases of nocardiosis are caused by the Nocardia asteroides complex and Nocardia brasiliensis. Here, we present a patient with a Nocardia abscessus brain abscess. The diagnosis was confirmed by DNA sequencing, and the organism was susceptible to linezolid, clarithromycin, ceftriaxone, imipenem, tobramycin, amikacin, minocycline and sulfamethoxazole. The patient was successfully treated medically in combination with surgical excision

Sub-cutaneous abscess caused by Nocardia asteroides in renal transplant recipient.

Nocardia is a significant opportunistic pathogen in patients with compromised immunity. Nocardia asteroides was isolated from subcutaneous abscesses on the left thigh and shoulder of a renal transplant recipient. Direct examination of the aspirated pus showed branching filaments that were gram-positive and acid fast. The abscesses were drained and the patient responded to high dose co-trimoxazole therapy.

case of actinomycotic mycetoma in hand treated successfully with co-trimoxazole and streptomycin

Mycetoma is a chronic infection involving cutaneous and subcutaneous tissues. We describe a 33-year old man who presented subcutaneous nodules with draining sinuses that extrude masses of the infecting organism. The etiologic agent of disease was identified as Nocardia asteroids by direct examination, culture of exudates and physiological tests. The lesions were completely eradicated by using combination of streptomycin and co-trimoxazole

Nocardiosis cutánea primaria / Primary cutaneous nocardiosis

Se presenta un paciente de 71 años, de sexo masculino, con nocardiosis cutánea primaria por Nocardia asteroides. Se describen las formas clínicas de nocardiosis cutánea, así como los tratamientos que pueden efectuarse

Infección por nocardia asteroides en un paciente con lupus eritematoso sistémico / Nocardia asteroides infection in a patient with systemic lupus erythematosus

Nocardia asteroides infection are unusually observed in sistemic Lupus erithematous (SLE) patients. They are generally associated to steroidal and immunosuppressive therapy. We report a 24 years old female with SLE diagnosed in 1994 who developed a severe preeclampsia in her first pregnancy requiring emergency caesarean section. Post partum acute renal failure and type IV lupus nephropathy were treated with hemodialysis, metilprednisolone, cyclophosphamide and prednisone. Three months later, while she was receving the fourth cyclophosphamide dose, she presented with a pleuro pneumonia and occipital abscess, both caused by Nocardia asteroides. She was treated with cotrimoxazole + cefixime and pleural decortication was required. Five months later, she developed Meningitis caused by Nocardia asteroides and hydrocephalus. She was treated with ceftriaxone, vancomycin, cotrimoxazole and ventricular shunting procedure. Two months later, a retroperitoneal abscess was diagosed and surgically drained but the patient died, due to a methicillin-resistant Staphylococcus aureus septicemia

Nocardiosis linfocutánea del cuero cabelludo causada por nocardia asteroides: primer caso reportado en la Argentina / Lymphocutaneous nocardiosis of the scalp by nocardia asteroides: report of the first case in Argentina

La nocardiosis es una infección localizada o sistémica de infrecuente observación. En piel puede desarrollar un síndrome linfocutáneo simil esporotricosis. Presentamos un paciente de 61 años que desarrolló nocardiosis linfocutánea por Nocardia asteroides tras un traumatismo menor en cuero cabelludo. En el presente artículo se discuten las formas clínicas de nocardiosis cutáneas. Se realiza una revisión de los casos publicados en nuestro país de nocardiosis linfocutánea, todos provocados por Nocardia brasiliensis y localizados en extremidades. Por lo tanto, comunicamos el primer caso de nocardiosis linfocutánea por Nocardia asteroides en la Argentina

Nocardiosis diseminada en tres pacientes inmunocompetentes / Disseminated nocardiosis in 3 immunocompetent patients

Nocardia asteroide infections, an aerobic actinomycete, have several forms and lungs, skin and brain are the organs most frequently involved. When the infection suspected, special staining methods must be ordered to identify the agent. We report three immunocompetent patients with disseminated nocardiosis, 2 presenting with nodular lesions of skin and lungs and one presenting with pulmonary involvement and brain abscesses. The importance of clinical suspicion and early diagnosis of nocardiosis is emphasized

Nocardiosis pulmonar en un paciente con síndrome de inmunodeficiencia adquirida / Pulmonary nocardiosis in a male patient with AIDS

Se presenta un paciente de sexo masculino portador de una nocardiosis pulmonar asociada a SIDA. La radiografía de tórax mostró un infiltrado heterogéneo hilioapical izquierdo y se observaron signos de cavitación en la tomografía lineal. El recuento de linfocitos CD4 fue de 70/mm3. El diagnóstico se realizó por el hallazgo del agente etiológico en el esputo. Con el tratamiento con trimetropina-sulfametoxazol se logró la mejoría clínica y la negativización de los cultivos de esputo. En forma asociada presentó: sarcoma de Kaposi, candidiasis cutánea y esofagogástrica y bacteriemia por Salmonella O.S.A.
