We report a case of Candida albicans meningitis in a male with human immunodeficiency virus (HIV) infection. This finding has seldom been reported, both in this group of patients and in those with other causes of immunosuppression or other underlying diseases. We discuss the clinical presentation and the features of cerebrospinal fluid, which showed only a mild inflammatory reaction as found in other fungal meningitis (basically cryptococcal) in AIDS patients. Finally, we emphasize the ineffectiveness of amphotericin therapy to achieve a complete microbiological cure and to prevent the relapse of meningitis in this patient. We also stress the need to make an early diagnosis in cases of fungal meningitis in patients with VIH infection, so that appropriate therapy is begun as soon as possible.

A patient with a positive human immunodeficiency virus (HIV) titer and cryptococcal meningitis suffered bilateral epithelial keratopathy caused by Encephalitozoon, which did not respond to sulfas, erythromycin, bacitracin, tobramycin, neomycin, polymyxin B, or fluconazole. Eventual administration of itraconazole for the meningitis apparently produced resolution of the long-lasting (2-month) ocular infection. This new oral triazole antifungal may be valuable against the increasingly prevalent microsporidial infections in patients with acquired immune deficiency syndrome. Debulking of the infection by corneal scraping may have contributed to the authors' success.

The 863 patients, aged 10 years and younger, treated at the Children's Chest Clinic of Bellevue Hospital during three decades (1953 through 1981) clearly indicated the success of antituberculosis therapy. There were no deaths from tuberculosis. Early treatment is associated with a reduction in the serious forms of disease, eg, meningitis, miliary disease, and bone infections, and with preventing death. Medication was well tolerated: only 1.1% of the patients had adverse reactions, all of which were reversible. Consistent compliance with medication of only 62% of patients is a challenge to the medical profession. Only 22.5% of mycobacterial cultures were positive. Long-term follow-up of patients was rewarding: seven pregnancies with healthy mothers and babies, and no reactivation of tuberculosis by later infections, even those such as measles or pneumonia. The severity of disease was related largely to patient's age (3 years and younger) and intimacy of contact, the highest rate being when the mother was the contact. The long-term experiences emphasizes the value of early identification, therapeutic compliance, and comprehensive contact, tracing in the future elimination of tuberculosis. Prophylactic therapy and close observation should be considered for contacts, especially those exposed to human immunodeficiency virus infections and addicted to drugs.

Five patients with AIDS and Listeria monocytogenes infection (three cases of bacteremia and two of meningitis) are reviewed. Four patients had prior or concurrent gastrointestinal illness. Two patients received corticosteroids. A 7- to 21-day course of ampicillin was administered with or without a 7- to 14-day course of gentamicin. This regimen was effective, with no evidence of relapse 7-8 months after therapy was discontinued. The relative infrequency of infection with L. monocytogenes in AIDS patients is unexpected. Tumor necrosis factor (TNF) appears to be essential in the inhibition of Listeria in vivo. Elevated levels of TNF in AIDS patients may be protective against listeriosis and thus help explain the low prevalence of listerial infection in this population. Nonetheless, although L. monocytogenes is an uncommon cause of illness in patients infected with the human immunodeficiency virus, it cannot be dismissed as a cause of undefined meningitis or sepsis.

We measured the levels of interferon-gamma (IFN-gamma) and neopterin in the serum and cerebrospinal fluid of 121 human immunodeficiency virus-seropositive (HIV+) and 62-seronegative (HIV-) individuals evaluated for neurologic disease. CSF levels of IFN-gamma and serum and CSF levels of neopterin were higher in HIV+ than in HIV- individuals. Patients with HIV- related meningitis and with opportunistic CNS infections had higher serum neopterin levels than HIV+ asymptomatic individuals. CSF levels of IFN-gamma were slightly higher in CSF of HIV+ individuals in all groups (0.31 +/- 0.03 U/ml) than in HIV- individuals (0.12 +/- 0.03). CSF levels of neopterin were similar in HIV+ asymptomatic individuals (6.9 +/- 0.7 nmol/l) and HIV- individuals (5.9 +/- 1.1), but were elevated in those HIV-infected individuals with neurologic disease, particularly patients with HIV-associated meningitis (72.1 +/- 13.3 nmol/l), opportunistic CNS infections (36 +/- 9.1), and inflammatory demyelinating polyneuropathies (32.4 +/- 17.2). Levels of neopterin correlated positively with levels of soluble interleukin 2 receptor and soluble CD8, 2 additional indicators of immune activation. In the absence of neurologic disease, levels of IFN-gamma and neopterin in both serum and CSF were stable for up to 4 years after seroconversion. These data suggest that increased CSF neopterin is associated with HIV-associated neurologic disease.

There is a paucity of published information available on extrapulmonary cryptococcosis (EC) in children infected with human immunodeficiency virus, the etiologic agent of the acquired immunodeficiency syndrome. We surveyed investigators in pediatric acquired immunodeficiency syndrome around the country regarding their experience with EC. Investigators from 33 (87%) of 38 institutions responded and information on 13 patients from 11 institutions was analyzed. EC was the acquired immunodeficiency syndrome indicator disease in 9 (69%) of 13 patients. Median age was 8 years with a range of 2 to 17 years. Human immunodeficiency virus risk factors were transfusion (5 patients), hemophilia (4 patients) and perinatal exposure (4 patients). Meningitis, seen in 62% of patients, was the most common clinical manifestation. Although 2 patients with fulminant disease died before therapy was started, 10 (91%) of 11 had a clinical response to amphotericin B with or without flucytosine. Our study indicates a spectrum of EC in pediatric human immunodeficiency virus infection ranging from fulminant, fatal fungemia to chronic meningitis and fever of unknown origin. Cryptococcosis was generally not the cause of death in patients who initially responded to amphotericin B therapy. Optimal antifungal therapy, including the role of fluconazole, warrants further study.

Fungal infections have gained importance recently. The major reason for this is the increasing number of patients with immunodeficiency. Systemic treatment of invasive fungal infections up to now has been based on relatively few antimycotic agents (amphotericin B, flucytosine, as well as the azole derivatives fluconazole and itraconazole). Only a few number of fungi cause the majority of opportunistic fungal infections. Candida albicans leads to severe mucosal infections in cases of immunodeficiency. Systemic mycoses usually present as endogenous infections or are caused by an infected central venous catheter with dissemination into multiple organs. Less severe candida infections should be treated with fluconazole. A more severe candida infection still requires treatment with amphotericin B plus flucytosine. Aspergillus fumigatus, a ubiquitous mold, is the most frequent pathogen in patients with granulocytopenia. First choice treatment also is amphotericin B and flucytosine; treatment should be started despite lacking proof of pathogen in patients with immunodeficiency and typical clinical signs. Itraconazole, the azole derivative active against aspergillus, may be administered only in mild cases of aspergillus infections in immunocompromised patients. Infections with Cryptococcus neoformans, which hardly ever occur, have been observed frequently in AIDS patients. The manifestation of cryptococcosis mainly presents as chronical meningitis. Presently various treatment concepts are being clinically tested. An initial combination of amphotericin B, flucytosine, and fluconazole, followed by long-term treatment with fluconazole, is recommended.

Although resistance to Listeria monocytogenes infection requires intact T cell-mediated immunity, only 20 patients with human immunodeficiency virus (HIV) infection and listeriosis (including one patient described herein) have been reported to date. Listeriosis developed before AIDS in five cases. Syndromes included meningitis in nine cases, bacteremia in nine, brain abscess in one, and endocarditis in one. Eighteen patients were treated with ampicillin, penicillin, or amoxicillin with or without aminoglycosides. Clinical and microbiologic responses were obtained in one patient with bacteremia treated with vancomycin and in one patient with meningitis treated with trimethoprim-sulfamethoxazole. Three of the nine patients with meningitis died, as did the patient with brain abscess. All nine patients with bacteremia and the patient with endocarditis survived. No case of relapse was documented. L. monocytogenes, although uncommon, should be considered in the differential diagnosis of febrile illness, meningitis, and brain abscess in patients with HIV infection.

Cryptococcosis is a common opportunistic infection in patients with AIDS. Meningitis is the most frequent manifestation of infection with Cryptococcus neoformans; pneumonia due to this organism, though less frequently recognized, is also a significant entity. A retrospective review was performed of all patients seen at Duke University Medical Center between January 1981 and July 1989 who were infected with both human immunodeficiency virus type 1 and C. neoformans. Of 31 patients with these concomitant infections, 12 had cryptococcal pneumonia (10 definite and two presumptive cases). Eleven of these 12 patients had evidence of extrapulmonary cryptococcal disease as well. Chest radiography showed interstitial infiltrates in 11 instances. For ten of the 12 patients, pulmonary cultures were positive for C. neoformans. Bronchoalveolar lavage fluid from all five patients who underwent bronchoscopy yielded the organism. Acute-phase mortality from cryptococcosis was 42% among patients with pneumonia. Cryptococcal pneumonia in patients with AIDS is probably more common than has previously been recognized and typically presents as interstitial disease that may mimic other opportunistic infections.

A 25 year old British man of previous good health presented with persistent generalised lymphadenopathy and was found to be human immunodeficiency virus (HIV) antibody positive. Three years later after weight loss and loose stools Strongyloides stercoralis was identified in the latter and successfully treated with thiabendazole. Shortly afterwards, a further episode again responded rapidly, but was swiftly followed by a final and fatal illness with severe debility and metabolic imbalance unresponsive to all treatment. Necropsy showed widespread and heavy strongyloidiasis with pulmonary haemorrhage, bronchopneumonia, and meningitis.
