Hypercalcemia in a patient with hypoparathyroidism and Nocardia asteroides infection: a novel observation.

Hypercalcemia is associated with numerous chronic granulomatous processes and chronic infections. Increased production of 1,25-dihydroxyvitamin D by activated macrophages has been shown to be the cause in most cases. In this article, we describe a case of hypercalcemia related to infection with Nocardia asteroides. In a 34-year-old woman who previously had hypocalcemia, acute hypercalcemia developed coincident with Nocardia pericarditis. The hypercalcemia resolved after treatment of N. asteroides with sulfisoxazole. Parathyroid hormone and phosphorus levels were within normal limits, and total 25-hydroxyvitamin D levels were only mildly increased. After successful treatment of the Nocardia infection, the patient required supplemental calcium and vitamin D. Her hypercalcemia was temporally related to the duration of the N. asteroides infection. We believe this is the first reported case of hypercalcemia associated with N. asteroides infection.

Nocardia thyroiditis: unusual location of infection.

Nocardia asteroides complex is an important opportunistic agent in immunocompromised hosts. Usually, primary pulmonary infection occurs and is followed by dissemination of the pathogen to the central nervous system and soft tissues. As described in the literature, almost every organ can be infected, but to our knowledge, Nocardia has been described as a pathogen responsible for thyroid abscess in only one report, which was published in 1993. The present report is the second case report of Nocardia thyroiditis. The patient was under immunosuppressor treatment following a combined liver-kidney transplant and presented with a preexisting nodular goiter which was probably a predisposing factor to the start and development of the thyroid infection.

Disseminated Nocardia asteroides infection in an immunocompetent woman following an arm injury.

A case of disseminated infection with Nocardia asteroides in a 55-year-old immunocompetent woman after mild trauma to the arm is reported. Secondary dissemination was identified in the skin, right kidney, liver, peritoneal cavity, lungs and thigh. The patient was successfully treated with surgical drainage and a 9-week course of antibiotics including cefotaxime, amikacin, chloramphenicol, trimethoprim/sulfamethoxazole (TMP/SMX) and doxycycline. The administration of TMP/SMX in combination with doxycycline was clinically beneficial despite in vitro resistance.

Repeated pulmonary infection by Nocardia asteroides complex in a patient with bronchiectasis.

A rare case of pulmonary nocardiosis was presented in a nonimmunocompromised patient who had chronic airway obstruction and bronchiectasis without corticoid treatment. The microbial diagnosis was established after isolating Nocardia in bronchial aspirate and sputum samples. An in vitro study showed sensitivity only to imipenem, netilmicine, amikacin and ofloxacin. The evolution was chronic, with multiple clinical recurrences in spite of prolonged antibiotic treatment. Finally, the eradication of Nocardia was achieved with the combination of imipenem and amikacin.

[New effective therapy of systemic infection with Nocardia asteroides].

A combination of amoxicillin with clavulanic acid (a beta-lactamase inhibitor) and the aminoglycoside amikacin proved effective in the treatment of advanced pulmonary nocardiosis in a 49-year-old man. The result accorded with preceding in-vitro and animal experiments and justifies this combination of drugs in the treatment of nocardiosis, especially if the causative organism is N. farcinica (N. asteroides, biovariety B).

A case of disseminated infection with Nocardia brasiliensis in a lung transplant recipient.

BACKGROUND: Infection with Nocardia species is an increasingly recognized complication of solid organ transplantation. Nocardia asteroides accounts for most transplant-related nocardiosis, while Nocardia brasiliensis rarely causes infection in organ transplant recipients. METHODS: We describe a case of disseminated infection with N brasiliensis in a single-lung transplant recipient who also had concomitant infections with viral and fungal organisms. RESULTS: Although the mortality rate is high in immunocompromised patients with disseminated Nocardia infection, our patient responded favorably to prolonged antimicrobial therapy. CONCLUSIONS: This case illustrates that N brasiliensis, like N asteroides, produces pulmonary disease and dissemination in solid organ transplant recipients, and demonstrates the utility of prolonged treatment with trimethoprim-sulfamethoxazole in Nocardia infections.

Nocardia brasiliensis: from microbe to human and experimental infections.

Nocardia brasiliensis is a Gram-positive bacterium that lives as a saprophyte in soil. In this article the physical properties, chemical composition and taxonomic position of this species is reviewed. Human infections and an experimental model of actinomycetoma in BALB/c mice as well as the host-immune response is described.

Brain abscess caused by Nocardia cyriacigeorgica in a patient with human immunodeficiency virus infection.

Nocardia cyriacigeorgica is a recently characterized species within the genus of Nocardia. We report a brain abscess, following a primary pulmonary colonization, due to this species in a human immunodeficiency virus-infected patient. This case confirms that isolation of Nocardia in sputum is associated with a high risk of disseminated infection in immunocompromised patients.
