Histoplasma meningitis (HM) has been reported to occur primarily in association with disseminated histoplasmosis (DH). We report a case of histoplasma meningitis occurring in a patient with common variable hypogammaglobulinemia (CVH) in which no manifestations of DH were observed. L. L., a 66-year-old Caucasian male, clerical worker, developed occasional episodes of dizziness and tinnitus in mid-1971. During 1972, increasing frequency of these episodes and gradually progressive confusion were noted. In January 1973, vomiting, forther confusion, obnubilation, and a left central facial paresis developed and he was hospitalized. Physical examination revealed no pulmonary abnormalities, lymphadenopathy or hepatosplenomegaly. Over the ensuing 6-week evaluation, there was occasional fever to 38.5 degrees C. Chest roentgenogram was normal. Cerebral angiography suggested a mass in the left cerebellar hemisphere. EEG was diffusely slow. Multiple CSF examinations revealed: Glucose 7-18 mg/with a normal blood glucose, protein 109-256 mg/and cells 66-140 (95 + % mononuclear). Histoplasma capsulatum was cultured from CSF but not from sputum, urine, blood or bone marrow. Skin tests for PPD, histoplasmosis, coccidiodomycosis, blastomycosis, mumps, dinitrochlorobenzene and streptokinase-streptodornase were negative then and 6 months later. Histoplasma serum antibody was absent. Immunoglobulin analysis revealed IgG 430 mg %, IgA 46 mg %, and IgM 35 mg %, which with the history and skin test results suggested CVH. Treatment with 2.51 gm of amphotericin B given intravenously over a 3-month period resulted in complete reversal of all neurologic signs and clearing of the confusion. The remission has been maintained for two years. This case represents a primary infection of the CNS by histoplasma. The relationship between the HM and the CVH will be discussed.

Histoplasma capsulatum is not endemic in Britain. We report a case of disseminated histoplasmosis in an English man who had not ventured out of northern Europe for 30 years. The disease presented as painful mouth ulcers and hepatosplenomegaly six months after he had developed maturity-onset diabetes. The origin of the infecting fungus may have been from within the United Kingdom or alternatively it may have existed as an intraoral saprophyte for over 30 years.

Two cases of disseminated histoplasmosis caused by H. capsulatum in Nigerian children are reported. This is a rare infection in this part of the world. The main clinical features were fever, weight loss, lassitude, lymphadenopathy, hepatosplenomegaly and severe anaemia, features indistinguishable from those of tuberculosis, Hodgkins and other reticuloses. Recognition of this infection in this environment is possible if it is considered in the differential diagnosis of pyrexia of undetermined origin and appropriate laboratory tests carried out on suitable specimens such as bone marrow, splenic aspirate or biopsy material. Treatment of choice is amphotericin B given intravenously, starting with 0-25 mg/kg. and increasing slowly to 1 mg/kg. Other useful drugs are Septrin and rifampicin which can be given concurrently. Subcutaneous abscesses and multiple bone lesions occurred in both our cases presumably as a result of blood stream infection, or embolisation from endocarditis.

Twenty-seven patients suffering AIDS and disseminated histoplasmosis were included in this study, comprising twenty-three males and four females, from 18 to 46 years of age (mean = 32.9). The most frequent clinical manifestations were fever, weight loss, anaemia, skin lesions, pulmonary micronodules, hepatosplenomegaly and adenomegalies. All of them presented other infectious diseases or neoplasias frequently found in AIDS patients. The diagnosis of histoplasmosis was based upon the finding of Histoplasma capsulatum in microscopic examination or in cultures from the following specimens: skin scrapings, bone marrow aspiration, bronchoalveolar lavage, blood cultures, buccal biopsies and lymph node biopsy. Serologic reactions, searching for antibodies, were positive in 11 cases. Itraconazole by oral route, at a daily dose of 200 mg (24 cases) or 400 mg (3 cases), was administered for 6 months. Those patients who were clinically cured after receiving this scheme of treatment were treated with itraconazole 100 mg day-1 as a suppressive therapy. Twenty-three patients were considered responders, 1 as a non-responder and 3 non-assessable. The average survival time was 7.8 months and eleven cases are still alive. Itraconazole proved to be a useful medication in disseminated histoplasmosis associated with AIDS and it was very well tolerated.

The case of a 58-years-old patient with AIDS is discussed. He presented a progressive disease with discomfort, abdominal pain, hiporexia, fever and weight loss. At the time of admittance in our hospital he had hepatosplenomegaly. The patient worsened and presented asthenia, fever, oedema, ascites, pulmonary congestion and finally jaundice and died. Autopsy findings were indicative of disseminated histoplasmosis with pseudotumoral appearance of the adrenal glands.

Disseminated histoplasmosis is a rare and potentially fatal disease caused by the dimorphic soil fungus Histoplasma capsulatum. We describe a 67-year-old man with diabetes who presented with a 6-month history of fever, weight loss, and mental deterioration; using computed tomography (CT), we found hepatosplenomegaly and bilateral adrenal masses. CT-directed adrenal biopsy showed yeast forms consistent with H capsulatum. Therapy with ketoconazole was accompanied by adrenal insufficiency (treated successfully with prednisone and fludrocortisone) and produced an excellent therapeutic response. We address the differential diagnosis of bilateral adrenal enlargement, and we discuss the clinical features, diagnosis, and treatment of disseminated histoplasmosis, a disease that includes parts of the Southwestern United States in its endemic region.

Disseminated histoplasmosis is being diagnosed more frequently in persons infected with the human immunodeficiency virus and is often the initial manifestation of the acquired immunodeficiency syndrome (AIDS). Disease-related cutaneous features of HIV-associated disseminated histoplasmosis are defined as mucocutaneous lesions from which fungal organisms were either cultured or demonstrated histopathologically. We report four HIV-seropositive patients with disseminated histoplasmosis who had culture-positive skin or oral lesions of histoplasmosis and review the specific cutaneous manifestations of HIV-associated disseminated histoplasmosis. Including our patients, disease-related skin and/or mucosal lesions were present in 11% of patients (26% of 239) with HIV-associated disseminated histoplasmosis. The possibility of disseminated histoplasmosis should be considered in all HIV-infected persons and in persons with AIDS risk factors who have fever, weight loss, hepatosplenomegaly, and new cutaneous lesions. An early skin or mucosal biopsy specimen for crushed tissue preparation, histologic evaluation, and fungal culture is a simple, rapid diagnostic procedure.

A 31-year-old white male homosexual was healthy until March 1984, when he developed Pneumocystis carinii pneumonia, which resolved with treatment. In April 1984 he developed fever, followed by hepatosplenomegaly, headaches, blurred vision, pancytopenia and pulmonary infiltrates. On June 11, intracytoplasmic yeast were noted within leukocytes on a peripheral blood smear, and amphotericin B was started. The patient developed progressive respiratory and renal insufficiency and died on June 13, 1984. Autopsy histopathology demonstrated disseminated histoplasmosis and Histoplasma capsulatum was cultured from numerous tissues. Ocular histopathologic examination using special fungal stains and electron microscopy revealed numerous budding yeasts characteristic of Histoplasma capsulatum in the choroid, retina and central retinal vein. Their identification as H. capsulatum was confirmed by immunofluorescent staining.

Histoplasma infections in Europe are rare, and acute disseminated histoplasmosis has only been observed in immunocompromised persons. We describe a case of acute disseminated histoplasmosis in a young, nonimmunocompromised European woman. The probable source of infection was Sri Lanka or the Maldives. At presentation she was severely ill with fever, lymphadenopathy, anemia, thrombocytopenia, hepatosplenomegaly, and polyserositis. Histologically, myelofibrosis and osteosclerosis were observed with extramedullary hematopoiesis. Histoplasma capsulatum yeasts were detected in bone marrow trephine biopsy by methenamine silver staining. Treatment with conventional and liposomal amphotericin B and subsequent itraconazole led to rapid and complete recovery.

Histoplasmosis is particularly common in Missouri, and many important clinical observations about the disease were made in this state in the 1950s and 1960s. When the AIDS epidemic spread to Missouri in the mid-1980s, histoplasmosis became recognized as a common and important opportunistic infection among Missourians with AIDS. Clinicians must maintain a high level of suspicion for histoplasmosis in any HIV-infected patient who presents with unexplained fever, particularly if the patient has evidence of hepatosplenomegaly, generalized lymphadenopathy, pancytopenia, abnormal liver function tests, or bilateral pulmonary infiltrates. The diagnosis of histoplasmosis can be established rapidly by observation of organisms on peripheral blood smear or bone marrow biopsy specimens or by Histoplasma Polysaccharide Antigen testing. The diagnosis can be confirmed by blood cultures in most cases. Histoplasmosis in AIDS is invariably fatal if not treated. Treatment consists of two phases: initial induction therapy and subsequent lifelong maintenance therapy. Amphotericin B and itraconazole are extremely effective for induction and maintenance therapy; fluconazole appears to be effective maintenance therapy. Strategies for the prevention of histoplasmosis in high risk patients are being evaluated currently.
