A 80 year-old male was transferred to our department on 18th Aug. 1988, for high fever and clouding of the consciousness. He had been treated with steroid hormone (betamethasone 3.0 mg/day for 15 days) for his uveitis. Enterococcus faecium was isolated from both blood and spinal fluid, and then Strongyloides sterocoralis was revealed both in the sputum and stool. Anti-Human T-cell leukemia virus 1 (HTLV-1) antibody was also positive serologically. At first, beta-lactam antibiotics were used for the treatment of purulent meningitis and sepsis, but after performing sensitivity tests for E. faecium, the antibiotics were changed to rifampicin (RFP), fosfomycin (FOM) and ofloxacin (OFLX) for their excellent activity against the organism. After the clinical symptoms, subsided, thiabendazole was used for disseminated strongyloidiasis in daily doses of 2,500 mg for six days initially. The drug was used three times with two week intervals. Both bacterial and parasite infections subsided and no recurrence has been noticed until now. This is the first case of meningitis caused by E. facium complicated with strongyloidiasis.

A review of two third-generation cephalosporins, ceftazidime and cefotaxime, is presented. Ceftazidime, often used as a single agent, has shown greater activity than cefotaxime against Pseudomonas aeruginosa and other Pseudomonas species, Enterobacteriaceae, Acinetobacter sp, and Enterobacter sp. It has been effective as monotherapy in the treatment of peritonitis, gynecologic infections, chronic bronchitis, and infections in patients with leukemia and granulocytopenia, as has cefotaxime when in combination with an aminoglycoside. Cefotaxime has shown good activity against most aerobic gram-negative bacilli and against Staphylococcus. It has been used in respiratory infections, urinary tract infections, and septicemia. In contrast to first-generation and most second-generation cephalosporins, third-generation cephalosporins have proven useful in some types of meningitis. Ceftazidime and cefotaxime successfully penetrate into the cerebrospinal fluid and cures of bacterial meningitis have been reported with both drugs. Both ceftazidime and cefotaxime have been successfully used in children, infants, and neonates, as well as adults. Safety profiles of ceftazidime compare favorably with those of other third-generation cephalosporins.

Our experience with group C streptococcal infection over the past 15 years demonstrates an important and emerging role for this hemolytic organism as an opportunistic and nosocomial pathogen. Significant risk factors in this predominantly male population included chronic cardiopulmonary disease, diabetes, malignancy, and alcoholism. Bacteremia occurred in 74% of cases seen in our series. Nosocomial acquisition of infection was observed in 26%, and infection was frequently polymicrobial in nature with gram-negative enteric bacilli isolated most commonly along with group C streptococci. We observed a broad spectrum of infections including puerperal sepsis, pleuropulmonary infections, skin and soft-tissue infection, central nervous system infection, endocarditis, urinary tract infection, and pharyngeal infections. Several cases of bacteremia of unknown source were observed in neutropenic patients with underlying leukemia. New syndromes of infection due to group C streptococci observed in our series included intra-abdominal abscess, epidural abscess, and dialysis-associated infection. Response to therapy and outcome was related to the underlying disease. While the literature suggests that patients with group C endocarditis respond better to synergistic penicillin-aminoglycoside regimens, patient numbers are too small to draw definite conclusions. The clinical significance of antibiotic tolerant group C streptococci remains uncertain. In patients with serious group C infections including endocarditis, meningitis, septic arthritis, or bacteremia in neutropenic hosts, we advocate the initial use of cell-wall-acting agents in combination with an aminoglycoside.

We report an unusual case of adult T-cell leukemia (ATL) initially manifesting as facial palsy due to ATL meningitis, which was caused by lymphoid cells in the cerebrospinal fluid (CSF) with a different phenotype from those in the blood. A DNA southern blot analysis of the blood cells confirmed the diagnosis of ATL. The aberrant cells in the CSF contained nuclei with simple indentations and responded well to the initial chemotherapy, while leukemic cells in the blood showed lobulated or convoluted nuclei and were resistant to treatment. Flow cytometry performed before treatment demonstrated that the majority of the cells in the CSF were CD3+CD4+CD8-CD25+, consistent with ATL, whereas they expressed the CD45R antigen, which the blood ATL cells did not. These differences in the subphenotype, cell morphology, and responsiveness to treatment among the ATL cells in blood and CSF suggest that a single clone or subclone with heterogeneous nature was not generated, before the final development of ATL.

A 69-year-old woman with human T-cell lymphotropic virus type I (HTLV-I) positive chronic myelopathy became comatose with acute meningitis. Most of the cells in the cerebrospinal fluid were similar to those found in adult T-cell leukaemia/lymphoma, which suggests that there is a close relationship between HTLV-I and this form of meningitis.

This retrospective hospital study concerns 159 infectious episodes observed in 60 patients with chronic lymphoid leukaemia (CLL) staged A, B or C on first admission. The most frequent site of infection was pulmonary (33%), followed by ENT and stomatological infections (15%), septicaemia (9%), urinary and genital tracts infections (9%), herpes virus infections (9%), skin and soft tissue purulent sepsis (8%), digestive tract (3%) and meningeal (1%) infections and isolated fever (8%). Seventy nine bacteria were isolated, including 35 Gram-positive cocci (Staphylococcus spp. 12, Streptococcus spp. 13, D. pneumoniae 5, Enterococcus spp. 5), 43 Gram-negative bacilli (Enterobacteriaceae 36, Pseudomonas spp. 5, Haemophilus influenzae 2) and 1 M. tuberculosis. The other documented infections were: candidiasis 11, viral infections 19 (including 17 of the herpes group) and 2 parasitoses (1 pneumocystosis, 1 toxoplasmosis). Sixteen patients died of toxic -infectious shock (9 cases, including 1 meningitis) or pneumonia (7 cases, including one chicken-pox). Stage C leukaemia and granulopenia (less than 1 X 10(9) PN/l) were associated with significantly more frequent and severe infections.

A total of 3,349 serum samples were screened by the immunofluorescence (IF) method for antibody to human T-cell leukemia virus type I (HTLV-I). Only 9 of 2,409 specimens from selected individuals, blood bank donors, patients with encephalitis-meningitis, and human immunodeficiency virus antibody-positive homosexual or bisexual men were reactive by IF. In addition, 940 serum samples from intravenous drug abusers were tested by IF and also by an HTLV-I enzyme immunoassay (EIA) method. Of these, 222 (24%) were positive for both HTLV-I and HTLV-II antigens by IF, and 191 of these 222 were also reactive in the HTLV-I EIA. Of the 31 IF-positive, EIA-negative serum samples, 20 exhibited optical density readings greater than or equal to 70% of the positive cutoff in the EIA, and 29 samples reacted with 1 or more bands in the Western blot (immunoblot) test. An additional 10 specimens that were EIA negative reacted only with HTLV-I by IF. Differences in staining morphology and in reactions on HTLV-I and HTLV-II antigens before and after absorption of the serum specimens with HTLV-I and HTLV-II-infected cell pellets revealed six distinct serological patterns by IF. These results indicate that infections by HTLV-I or by another closely related retrovirus(es) occur in California. Further studies utilizing statistically valid sampling methods are needed to estimate true prevalence rates among various groups. IF and Western blot tests should supplement the EIA method to maximize sensitivity and specificity of test procedures.

Listeria monocytogenes is an uncommon cause of brain abscess. Of a total of 14 cases of L. monocytogenes brain abscess (one described for the first time and 13 reported previously in the English-language literature), seven (50%) occurred in patients with leukemia and recipients of renal transplants; four (29%) of the cases occurred in previously healthy individuals. Common clinical findings were similar to those in brain abscess due to other causes and included fever (57%), headache (57%), and focal neurologic signs (64%). Distinctive, however, was the unusually high frequency of associated meningitis and bacteremia; blood cultures were positive in all eight cases in which they were performed. Eight (57%) of the 14 patients died. L. monocytogenes should be included in the differential diagnosis of brain abscess in patients with leukemia and in renal transplant recipients. Listerial brain abscess is highly unlikely when blood culture results are negative.

Two cases of promyelocytic leukemia (APL) with central nervous system leukemia (CNS-L) are reported. The first case displayed some symptoms similar to meningitis at onset, and the second case, during induction therapy suddenly developed left hemiplegia and was found to have CNS-L. There have been only a few case reports of APL associated with CNS-L and each has said that APL was rarely accompanied by CNS-L. Yet, of the reports registered with the Joint Committee for Hematologic neoplasm in Japan, the incidence of APL with CNS-L is not much lower than any of the other types of acute non-lymphocytic leukemia that can accompany a CNS-L. There fore, we feel that CNS-L should not be overlooked as an important prognostic consideration in APL cases.

We studied sialic acid in the cerebrospinal fluid (CSF) of 52 children with leukemia and 51 children with non-leukemic diseases. The CSF sialic acid concentration in the children with central nervous system (CNS) leukemia was significantly higher than that in the children with acute lymphoblastic leukemia without CNS involvement, acute non-lymphocytic leukemia without CNS involvement, non-hemopoietic diseases, non-suppurative meningitis, epilepsy, and other neurologic diseases. Serial determinations revealed a rapid decline in the CSF sialic acid concentrations in the patients with CNS leukemia who responded well to the therapy and who were free from relapse of CNS leukemia. The simultaneously determined CSF beta 2 microglobulin concentration did not show any significant changes. These results suggest that the CSF sialic acid may be a good indicator of CNS leukemia.
