The incidence and prevalence of histoplasmosis in Southeast Asia has not been extensively described. The first microbiologically documented case of disseminated histoplasmosis with cutaneous papulonodules in a 56-year-old woman from the Philippines is reported. She presented with fever and generalized papulonodular lesions in various stages, which evolved into vesicles with central necrosis that resembled molluscum contagiosum with an indurated erythematous halo. Biopsies revealed a granulomatous mass of lymphohistiocytic and epithelioid cells with intracellular budding yeast cells and dark nuclei. Cultures were positive for Histoplasma capsulatum. The patient was treated with amphotericin B (3 g) and 5-fluorocytosine (50 mg/kg/day), followed by ketoconazole (400 mg/day). Her clinical course was complicated by intractable hemolytic anemia that was initially treated with corticosteroids. A splenectomy was subsequently performed. Pneumonia and a brain abscess caused by Nocardia asteroides were secondary complications. Nine months after her admission, repeat testing was diagnostic for systemic lupus erythematosus. This patient serves to re-emphasize that cutaneous lesions in an immunocompromised patient must be evaluated by biopsy and culture analysis. Disseminated histoplasmosis in the immunocompromised host may present with unusual cutaneous lesions, and must be considered even in a nonendemic area.

Out of 110 cases of fever of unknown origin (FUO) that met Petersdorf and Beeson's criteria 15 patients were selected because of prolonged FUO with more than six months elapsed between admission and the final diagnosis. In this group of chronic FUO an etiological diagnosis was reached in 11 cases, distributed as follows: four cases with infections (two with toxoplasmosis, one with brucellosis, and another with a brain abscess); one with colon carcinoma; two with collagen-vascular diseases (systemic lupus erythematosus, temporal arteritis); and four with different diseases (two with familial mediterranean fever, one with idiopathic granulomatous disease, and another with factitious fever). In four cases no cause for the FUO could be determined. The procedures used to obtain the diagnosis were non-invasive in five cases (clinical course and serological tests), and invasive in another five (angiography, biopsies, and exploratory laparotomy). In one case the ethology could only be ascertained at autopsy. In the FUO with a prolonged course the peculiar etiological spectrum, the lesser yield of invasive procedures, and a mortality inferior to that of FUO in general all deserve special emphasis.

Nocardia is an important but often overlooked opportunistic infection agent in immunocompromised hosts. Nocardiosis is primarily pulmonary; central nervous system involvement, usually in the form of brain abscess, is less common. Primary nocardial meningitis without associated brain abscess and pulmonary lesion is extremely rare and poses a formidable diagnostic challenge. We report on a patient with systemic lupus erythematosus who presented with a clinical picture of chronic meningitis which failed to respond to empirical antibiotic treatment. She deteriorated and succumbed. Post-mortem examination showed nocardial meningitis without associated brain abscesses. Nocardial meningitis should be considered a differential diagnosis of subacute meningitis in immunocompromised hosts.

The clinical use of antithymocyte globulin is rarely reported in patients with rheumatic diseases. We describe the use of this agent in a patient with systemic lupus erythematosus who concomitantly developed severe pancytopenia. High-dose methylprednisolone therapy had been unsuccessful in controlling either the disease exacerbation or the pancytopenia. Antithymocyte globulin and cyclosporin A were therefore administered to achieve immunosuppression. The exacerbation of disease activity was gradually lessened, except for persistent thrombocytopenia and anaemia. Severe and persistent immunosuppression, however, led to a fatal brain abscess. The combined use of both antithymocyte globulin and cyclosporin A induced potent immunosuppression, and should be confined to selected patients with systemic lupus erythematosus, and administered under detailed monitoring.

A 58 year old woman had a long history of immunocompromised state. Since age 28 she had multiple endocrine neoplasm type 2A: her thyroid gland and bilateral adrenal glands were removed because of pheochromocytoma and thyroid medullary carcinoma. Corticosteroid and levothyroxine were supplemented. At age 57 she was afflicted with systemic lupus erythematodes and nephrotic syndrome. Prednisolone therapy was started. Two months later she developed fever, lethergy, headache and left hemiparesis. MRI revealed multiple ring-enhancing lesions in the right cerebrum. CSF was negative for microorganisms. Blood culture hemolysed after 24 hours. Direct gram staining of the blood culture sample revealed gram-positive short rods without spore, suggested listeria. This enabled prompt initiation of high dose penicillin therapy before the official report of listseria infection. Neurological abnormality including left hemiparesis disappeared completely within one month. Enhancement of abscess wall decreased every month, but it persisted for five months despite continuous intravenous penicillin therapy. Listeria monocytogenes is well-recognized as an opportunistic pathogen. It requires prolonged therapy with antibiotics, since it is the intracellular organism. Monitoring of the brain abscess wall by the enhanced MRI is useful to determine the completion of therapy. Since listerial contamination is common among raw meat and unpasteurized milk, immunocompromised patients should be alarmed not to eat uncooked food products.

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.

A 70-year-old woman with systemic lupus erythematosus presented with a brain abscess manifesting as progressive monoparesis of the right lower extremity over 4 days. She had had no episodes of fever, and did not complain of headache or exhibit any signs of meningeal irritability. Computed tomography of the brain showed a round, low-density mass with strong ring enhancement in the left frontal lobe. Laboratory examination found a moderately elevated serum level of CA19-9, a marker of some digestive organ cancers. Together with the absence of febrile episodes, headache, and a rise in leukocyte count, the initial suspicion was metastatic brain tumor rather than brain abscess. However, diffusion-weighted magnetic resonance imaging depicted the mass as a very hyperintense area. The neuroimaging diagnosis was brain abscess. After conservative treatment with intravenous antibiotics for 6 weeks, the brain abscess completely resolved, and the patient was discharged without neurological deficits.

A 26-year-old woman currently treated for systemic lupus erythematosus with steroid therapy presented with sudden onset of right hemiplegia. Computed tomography of the brain showed a large frontoparietal ring-enhanced lesion with perifocal edema. Stereotactic aspiration of the lesion revealed Cladosporium bantianum. The size of the abscess did not reduce in spite of optimum antifungal treatment. The abscess was subsequently excised through a frontoparietal craniotomy. At follow up after 24 months, there was no recurrence of the abscess. Cerebral Cladosporium bantianum infection is usually refractory to antifungal agents and the prognosis is very poor. This patient had the longest survival period in a case of Cladosporium brain abscess so far reported.

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.

Nocardiosis has become a significant opportunistic infection over the last two decades as the number of immunocompromised individuals has grown worldwide. We present two patients with nocardial brain abscess. The first patient was a 39-year-old woman with systemic lupus erythematosus. A left temporoparietal abscess was detected and aspirated through a burr-hole. Nocardia farcinica infection was diagnosed. The patient had an accompanying pulmonary infection and was thus treated with imipenem and amikacine for 3 weeks. She received oral minocycline for 1 year. The second patient was a 43-year-old man who was being treated with corticosteroids for glomerulonephritis. He was diagnosed with a ring-enhancing multiloculated abscess in the left cerebellar hemisphere, with an additional two small supratentorial lesions and triventricular hydrocephalus. Gross total excision of the cerebellar abscess was performed via a left suboccipital craniectomy. Culture revealed Nocardia asteroides, and the patient was successfully treated with intravenous ceftriaxone, then oral trimethoprime-sulfamethoxazole for 1 year. The clinical course, radiological findings, and management of nocardial brain abscess are discussed in light of the relevant literature, and current clinical management is reviewed through examination of the cases presented here.
