A patient with systemic lupus erythematosus developed unexplained fever, nonregenerative anemia, leukopenia, and elevations in serum triglyceride and ferritin levels. Bone marrow studies established the diagnosis of macrophage activation syndrome with active hemophagocytosis. No infectious cause was found but pulmonary nocardiosis developed during the course of the disease. Intravenous gammaglobulin therapy was followed by a transient remission. Cyclophosphamide was given subsequently. In lupus patients, macrophage activation syndrome is exceedingly rare and has the same clinical, laboratory, and histologic features as those seen in patients with hemopathies, infections, or immune deficiencies. Investigations for an underlying infection are often negative, suggesting that the macrophage activation syndrome is due to lupus-related immune changes. Treatment is not standardized and relapses are common. This diagnosis should be considered in lupus patients with febrile pancytopenia.

We report a case of acute primary cutaneous infection of traumatic origin caused by Nocardia asteroides, appeared as cellulitis in a patient with systemic lupus erythematosus. Diagnosis was established by direct examination and cultures from aspirate specimens. The clinical forms of Nocardia infections that affect the skin, reported in Rio Grande do Sul and Uruguay, are discussed.

We report a case of acute pleuropulmonary nocardial infection in a 24-year-old woman suffering from systemic lupus erythematosus. In most instances, No-cardia asteroides is an opportunistic pathogen. In our patient, the infection was facilitated by systemic lupus erythematosus and chronic use of corticosteroids and immunosuppressive drugs. N. asteroides was cultured from both pleural effusion and blood. No extrathoracic location was found and the patient improved upon intravenous antibiotics and pleural drainage. Owing to the poor tolerance of trimethoprim/sulfamethoxazole, the patient was treated successfully with imipenem. The predisposing factors, the clues to the diagnosis and the therapy of nocardiosis are briefly reviewed.

Infection is a frequent problem in patients with systemic lupus erythematosus (SLE), especially in those hospitalised with complications of disease. Infections contribute greatly to the morbidity of patients and are one of the commonest causes of death. The high frequency and unusual spectrum of infections can be attributed to the multiple disturbances of immune function in SLE in combination with the effects of immunosuppressive therapy. High doses of corticosteroids are particularly implicated as a risk factor for infection, although cyclophosphamide may also play a role. The majority of infections where a pathogen can be identified are due to typical gram-positive and negative bacteria. However, there is increasing evidence to indicate that opportunistic infections make a large contribution to the infectious mortality in SLE. Opportunistic infections are considerably under-reported due to difficulties in diagnosis pre-mortem and the fact that they can mimic or be superimposed upon active lupus. The presenting features of tuberculosis, listeriosis, nocardiosis, candidiasis, cryptococcal meningitis, Pneumocystis carinii pneumonia and invasive aspergillosis in patients with SLE are discussed in this review, with particular attention to presentation in SLE patients in Asia. Heightened awareness of the potential for opportunistic pathogens to infect SLE patients, together with earlier investigation and appropriate therapy for such infections, are likely to make a significant contribution to decreasing the mortality in patients with SLE.

A 37-year-old patient with systemic lupus erythematosus, who had been treated with oral corticosteroids for 10 years, developed primary cutaneous nocardiosis. Brown-violaceous, suppurative nodules and plaques arose on her right leg. Cultures of multiple biopsies on blood agar medium grew Nocardia. The patient received 500 mg of imipenem three times a day which resulted in complete regression of the lesions within two months. No relapse was observed 6 months later.

A patient with systemic lupus erythematosus (SLE) developed primary subcutaneous nocardiosis during steroid and cyclophosphamide therapy for diffuse proliferative glomerulonephritis. In spite of local process the patient manifested signs of general deterioration mimicking SLE exacerbation. The diagnosis was made by bacteriologic examination of the material obtained by CT guided aspiration. Surgical drainage and systemic treatment with trimethoprim/sulphamethoxazole (TMT/SMZ) 960 mg twice/d led to a clinical recovery and enabled the continuation of the steroid and cytotoxic regimen.

We report a patient with systemic lupus erythematosus (SLE) complicated with nocardiosis. This case is very important that the complication of nocardiosis in SLE is very rare and the treatment to both SLE and nocardiosis is very difficult. A twenty-one-year old female was admitted to our hospital because of thoracic empyema and active lupus nephritis. Her medical history revealed that the diagnose of SLE was made when she was 18 with lymphocytopenia, proteinuria, positive antinuclear antibodies, and high titer of antibodies to native DNA. She was treated with prednisolne 60 mg daily and became better. Proteinuria appeared again in September 1995 and she was admitted to the former hospital. Renal biopsy proved diffuse proliferative glomeluronephritis (WHO IVb). She was treated with 1 g per day of methylprednisolone for 3 days and succeeded with 60 mg day of prednisolone. In early November she developed left chest pain and fever and chest X-ray demonstrated left pleural effusion. Antibiotics, antituberculosis, and antifungal therapy failed to subside her pleuritis and it turned to empyema. Then she was transferred to our hospital for further treatment. Nocardia farcinica was detected from the aspirated pleural fluid obtained at the former hospital. Drainage and intrathoracic impenem injection were effective. While long usage of minocycline was continued for the nocardiosis, 500 mg of cyclophosphamide pulse therapy to lupus nephritis was administrated. Two weeks later a new pulmonary lesion with left chest pain and liver abscess developed. Administration of trimethoprim-sulfamethoxazole subsided the nocardiosis. She was discharged with 1 g per day of proteinuria the prescribed 13 mg per day of prednisolone and continuous TMP-SMZ intake for nocardial infection. When immunosuppressive therapy must be given to the immunocompromised host, a more potent therapy must be added to avoid infection.

Nocardia, a gram positive variably acid-fast aerobic bacterium is an opportunistic pathogen in immunocompromised hosts. We present 5 cases of nocardiosis in patients with systemic lupus erythematosus. We emphasize the clinical features, radiologic findings, and antibiotic sensitivity. Lung involvement was the predominant manifestation; others include brain abscess, retinitis, thyroiditis, and diaphragmatic infiltration. We describe the first cases of pulmonary nocardiosis presenting as pneumothorax and the use of fine needle aspiration cytology in diagnosing nocardial thyroiditis.

The authors report the case of a 43-year-old woman suffering from severe systemic lupus erythematosus treated with long-term prednisone, who developed Nocardia nova infection on a hip prosthesis. Sepsis occurred about two years after an episode of pulmonary nocardiosis with the same Nocardia species, that was successfully treated by 12 months of antibiotics. A good outcome of the joint infection was observed in response to antibiotics and removal of the prosthesis. Nocardiosis is a rare infection, acting as an opportunistic infection, facilitated in the present case by systemic lupus erythematosus and chronic corticosteroid therapy. Nocardia infections mainly affect the lungs, skin and central nervous system; these last two sites are mostly due to haematogenous spread, a frequent event. Treatment is based on antibiotics, usually continued for 3-12 months, especially because of the risk of relapse. The imipenem-amikacin combination appears to be more effective than trimethoprim sulfamethoxazole. To our knowledge, this is the first case report of Nocardia nova joint prosthesis infection also presenting as late septic spread of pulmonary nocardiosis, complicating corticosteroid-treated systemic lupus erythematosus.

Nocardial infections in an immunocompromised host have been increasingly reported. Nocardial brain abscess, the most common presentation of nocardiosis in the central nervous system, is associated with a high mortality rate because of its delayed diagnosis and its unresponsiveness to the usual antibiotic therapy. We report four patients who experienced a long-term cure of nocardial brain abscess due to treatment by a combination of surgery and postoperative antibiotic therapy; 1 man and 3 women, ages ranging from 43 to 67 years old. Two patients were associated with systemic lupus erythematosus and two with autoimmune hemolytic anemia. Patients underwent surgical aspiration and drainage of brain abscess. Nocardia was identified from the aspirated specimen and postoperative antibiotic therapy for 5-6 weeks was performed using effective antibiotic agents; sulfamethoxazole/trimethoprim (ST), imipenem/cilastatin and minocycline (MINO) in Case 1, ST and MINO in Case 2, erythromycin in Case 3, and panipenem/betamipron and cefotaxime in Case 4. Case 3 and Case 4 with multilobulated brain abscess underwent total excision of the brain abscess. All patients showed successful cure of nocardial brain abscess with no recurrence for the period of 1-8 years. The combination of surgery and postoperative antibiotic therapy provides a good prognosis for nocardial brain abscess.
