Strongyloides stercoralis hyperinfection syndrome is a rare complication of strongyloidiasis that occurs in immunosuppressed patients. It is caused by increasing autoinfection of the host by the nematode, leading to serious superimposed enterobacterial sepsis. Once established, it has a high fatality rate. Two cases are reported of Strongyloides hyperinfection in patients with lymphoma who presented with purulent meningitis. Both were receiving combination chemotherapy that included high-dose corticosteroids, and neither was granulocytopenic at infectious onset. The patients had respiratory insufficiency that required mechanical ventilation and serious septic episodes. Both were treated with thiabendazole, and one survived with clearance of the larvae. These cases illustrate the possibility of strongyloidiasis hyperinfection as an underlying diagnosis of purulent meningitis and serious septic episodes in lymphomatous patients. It may occur even without granulocytopenia.

Many kinds of microorganisms can produce toxic septicemia in immunocompromised hosts. We are reporting alpha-hemolytic streptococcal septicemia and meningitis in two children with hematological malignancies. [Case 1] 6 year old girl who had been suffering from acute lymphocytic leukemia. She had sepsis and bacterial meningitis in maintenance-therapy for leukemia. Streptococcus sanguis was isolated from the blood and cerebrospinal fluid (CSF). [Case 2] 11 year old girl who had had malignant lymphoma (non-Hodgkin type). She also had sepsis and bacterial meningitis due to Streptococcus mitis which was isolated from blood and CSF in maintenance-therapy. Both cases had been treated with anti-cancer drugs and had severe granulocytopenia. Positive rate of blood cultures during the recent 6 years (1984.1-1989.12) at our department was 6.0% (total number of cultures were 2,019, positive cultures were 121). Strains of 131 bacteria were determined; Gram-positive cocci were 70 strains (53.4%) and Gram-negative rods were 52 strains (39.7%). Fifteen strains (11.5%) of alpha-hemolytic Streptococci were isolated during 6 years. One hundred thirteen cases of septicemia were analysed in medical charts and 12 cases of alpha-hemolytic streptococcal septicemia were observed (5 cases with infective endocarditis and 7 cases in immunocompromised states).

Ten patients with severe hematologic malignancies (four with acute leukemia, three with multiple myeloma, one with prolymphocytic leukemia, one with malignant lymphoma and one with blastic crisis of chronic myelogenous leukemia) developed respiratory failure during the period between April 1986 and May 1990. Clinically, the patients manifested high-fever, dyspnea refractory to oxygen therapy, diffuse pulmonary rales and severe hypoxemia without evidence of cardiogenic pulmonary edema. Chest roentgenograms displayed diffuse alveolar infiltrates. Respiratory failure occurred as early as 48 hours and as late as 66 days after the administration of intensive anti-neoplastic chemotherapy. At that time leukocyte count was between 100/microliters and 54,900/microliters. Marked leukocytosis was observed in two patients with AML and PLL. Respiratory failure was preceded by sepsis in one patient with AML and by pneumonia in nine patients. DIC was diagnosed in four patients. All patients treated with high dose methyl prednisolone (mPSL) within 12 hours after the onset of respiratory failure. Only one patient required assisted ventilation. High dose mPSL had significant effect on seven of ten patients. But three patients died from progressive respiratory failure, sepsis, pneumonia and multi-organ failure.

The effectiveness of sulbactam/cefoperazone (SBT/CPZ) on severe infections associated with hematological diseases was evaluated in a nation-wide multicenter clinical study. SBT/CPZ (4-6 g/day), a 1:1 combination of SBT and CPZ, was given intravenously to 437 patients with hematological disorders. The underlying diseases included acute nonlymphocytic leukemia, acute lymphocytic leukemia, malignant lymphoma, multiple myeloma, myelodysplastic syndrome and others. Thus, 94.3% of the patients had hematological malignancies. The complicating infections included sepsis in 41 cases; sepsis suspected in 205; pneumonia in 47; urinary tract infection in 15; fever of unknown origin in 59; and others in 70. Clinical efficacies of SBT/CPZ were as follows; markedly effective, 83 cases; effective, 170; fairly effective, 59; and ineffective, 110. The efficacy rate (markedly effective plus effective) was 60.0% as a whole. The efficacy rate of SBT/CPZ in sepsis and suspected cases, which accounted for 56.3% of the infections, was 59%. Mild side effects such as skin rash were observed in 15 patients (3.1%). As for abnormal laboratory test results, transient increases in GOT, GPT, A1-P, LDH, etc. were observed in 42 patients (8.6%). Therefore, SBT/CPZ is considered to be a useful drug in empiric therapy for severe infections associated with hematological diseases.

Patients with extensive lower extremity ulcerations initially thought to be vascular disease were subsequently proved to have pyoderma gangrenosum and malignant lymphoma. Both patients died of sepsis; one patient exhibited hypogammaglobulinemia involving immunoglobulins IgA, IgG, and IgE; in the second patient, a polyclonal excess involving IgA and IgE was present.

Among patients examined at the Central Laboratory of Yokohama City University Hospital over the 25 years from 1965 to 1989, those whose clinical samples showed Cryptococcus were studied in greater detail. The following findings were obtained. Of 16 patients who were found to have cryptococcosis, 14 (87.5%) were treated at the department of internal medicine, and one each at the departments of neurosurgery and dermatology. A study of these patients in terms of clinical type revealed 10 patients (62.5%) with meningitis, two with pneumonia and one with sepsis. The remaining three patients had complicated diseases: meningitis with sepsis, pneumonia with cutaneous cryptococcosis, or pleuritis with sepsis. Underlying disease, including liver cirrhosis, leukemia, multiple myeloma, malignant lymphoma and collagen disease, was found in 6 patients (37.5%), who were all from the department of internal medicine. All patients but one were given antimycotic agents. They were treated by a combination therapy except for three patients who received single amphotericin B (AMPH) therapy. The most frequent combination was AMPH + 5-flucytosine (5-FC), which was found in 7 cases. Seven patients (43.4%) died, three males and four females. Analysis of these cases in terms of clinical type revealed meningitis in four, and pneumonia, sepsis, or pleuritis complicated with sepsis in the remaining three patients. Four patients (57.1%) had underlying diseases. In addition, eleven strains isolated from the specimens were examined for serotypes and minimum inhibitory concentration (MIC) using three types of antimycotic agents. Serotypes of Cryptococcus neoformans were all A and the MIC was 0.1-0.39 micrograms/ml for AMPH, 0.05-0.2 micrograms/ml for 5-FC and 0.2-0.78 micrograms/ml for miconazole (MCZ).

The efficacy and the safety of an antibiotic in cephamycin group, cefbuperazone (CBPZ), were investigated in 93 patients with severe infections complicated with hematological disorders. The efficacy evaluation was made in 85 cases with underlying hematological disorders including 49 cases (57.6%) of leukemia and 18 cases (21.2%) of malignant lymphoma. The overall efficacy rate was 50.6% of the 85 evaluable cases. The clinical efficacy rate for sepsis and suspected sepsis was 53.4%. The most frequently used group of antibiotics for combination therapy was aminoglycosides in 37 cases, in which an efficacy rate of 62.2%, a higher rate than the efficacy rate of 48.5% for all the combination therapy cases, was obtained. In 16 cases in which penicillins were used as combination drug, the efficacy rate obtained was low, 31.3%. Efficacy rates obtained for cases with different neutrophil counts at the start of therapies were as follows: 52.2% in 23 cases with neutrophil counts below 100/mm3, 46.2% in 13 cases with neutrophil counts between 100 and 499/mm3 and 51.3% in 39 cases with neutrophil counts equal to or above 500/mm3, thus no significant differences in efficacy rates were observed for patients with different neutrophil counts. These results appear to suggest that CBPZ, alone or in combination with other antibiotic such as aminoglycosides, may be quite useful in the treatment of severe infections in patients with hematological disorders.

We report clinical and pathologic findings in 22 patients with Wegener's granulomatosis collected from 1966 to 1989. Ten cases were analyzed retrospectively. Organs affected included the lungs (n = 18), upper airways (16), kidneys (15), musculo-skeletal system (10), eyes (8), skin (7) and ear (5). Clinical manifestations of airway involvement included nasal obstruction, dysphonia and epistaxis. Lung involvement was evident in chest X-rays in 18 patients, 14 with a nodular aspects. Histologic study in 14 of these patients showed necrotizing and granulomatous vasculitis. Clinical evidence of nephropathy was evident in 15 patients and led to rapidly progressive renal failure in 8. Biopsy in this group (n = 14) revealed focal glomerulonephritis in 6 and diffuse disease in 8. Overall, 13 patients died: 5 without diagnosis, 4 from renal failure, 2 from sepsis, 1 from a lymphoma developing 3 years after immune suppressive therapy and 1 from unknown causes. Among survivors, one received a renal transplant and one remains in chronic dialysis. The diagnosis of Wegener's granulomatosis is therefore based on clinical findings including rhino pharyngeal, pulmonary and renal manifestations.

The principles of dose-response and combination chemotherapy were basic to the design of the initial curative standard-dose treatment regimens for leukemias, lymphomas, and testis cancer. Agents were selected with different dose-limiting toxicities, resulting in subadditive toxicity in combination. A fourth principle in the design of curative regimens was to combine agents with different mechanisms of action to avoid cross-resistance. Based on these principles, combinations of the highest tolerated doses of active noncross-resistant agents are required to decrease the emergence of drug resistance and achieve optimum cytotoxicity. Hematopoietic stem-cell support provides a mechanism for significantly increasing the doses of active agents, a strategy that has resulted in the cure of 10% to 50% of selected patients with lymphoma who could not be cured with standard-dose therapy. The lack of sufficiently effective cytoreductive conditioning regimens remains the major impediment to improving the high-dose therapy of patients with solid tumors. In this study, 27 patients with solid tumors were treated with a combination of cyclophosphamide, thiotepa, and carboplatin (CTCb) in a phase I-II study. Severe mucositis and neurotoxicity were dose-limiting. The maximum-tolerated dose (MTD) of the combination was 6.0 g/m2 of cyclophosphamide, 500 mg/m2 of thiotepa, and 800 mg/m2 of carboplatin. There were two deaths (7%) of sepsis, and an overall response rate of 72% in refractory tumors (81% in breast cancer). CTCb is a combination with low morbidity and high cytoreductive efficacy designed to exploit the principles of curative cancer chemotherapy.

We have treated 20 adult patients with acute lymphoblastic leukemia (ALL) and 2 patients with lymphoblastic lymphoma with a protocol modified from L-10M of the Memorial Sloan Kettering Cancer Center. Eighteen patients (81.8%) entered complete remission (CR). Eight of them eventually relapsed (only 1 patient had a meningeal relapse) and died. Median CR duration was 19 months (median overall follow-up of 35 months and 50% remission duration was not yet determined. Median overall survival was 19 months. Three patients died of sepsis during remission induction, but all of other deaths were due to resistant or relapsed leukemia. The four patients who completed 3.5 year's modified L-10M protocol were free from relapse for 6-11 months (mean 8.7). Although further follow-up is necessary, we suggest that modified L-10M protocol is effective for adult ALL and long-term survival may be available.
