Lihua Yang, Lihua Yu, Xinxin Chen, Yanqun Hu, Bin Wang
BACKGROUND: Vincristine (VCR) is a major chemotherapy drug for treatment of childhood acute lymphoblastic leukemia (ALL). Triazole antifungal drugs (AFD) are the main agents for the prevention/treatment of invasive fungal infection (IFI), a common complication during the treatment of ALL. This study investigated the adverse drug reactions (ADRs) between VCR and AFD. MATERIAL AND METHODS: A retrospective study was performed on 68 children with ALL (39 boys and 29 girls, median age: 5 years) who were treated with VCR chemotherapy (a total of 136 cases, including both induction and reinduction phases) from January 2012 to December 2013 in our hospital...

Guidelines recommend targeted antifungal prophylaxis for liver transplant (LT) recipients based on tiers of risk, rather than universal prophylaxis. The feasibility and efficacy of tiered, targeted prophylaxis is not well established. We performed a retrospective study of LT recipients who received targeted prophylaxis (n = 145; voriconazole [VORI; 54%], fluconazole [8%], no antifungal [38%]) versus universal VORI prophylaxis (n = 237). Median durations of targeted and universal prophylaxis were 11 and 6 days, respectively (p < 0...

Aspergillus fumigatus is an opportunistic pathogen responsible for life-threatening infections in immuncompromised patients. Data about the in vitro pharmacodynamics of antifungals against A. fumigatus are limited. In the present study, we investigated the fungicidal activities, at concentrations of 1, 4 and 16 times the minimum inhibitory concentration (MIC), of caspofungin (CAS), amphotericin B (AMB) and voriconazole (VORI) against eight A. fumigatus isolates through the use of time kill and 2,3-Bis [2-methoxy-4-nitro-5-(sulfenylamino) carbonyl-2H-tetrazolium-hydroxide] (XTT) reduction tests...

BACKGROUND: Because activation of T cells is associated with human immunodeficiency virus (HIV) pathogenesis, CD4 and CD8 activation levels in patients coinfected with HIV and hepatitis C virus (HCV) may explain conflicting reports regarding effects of HCV on HIV disease progression. METHODS: Kaplan-Meier and multivariate Cox regression models were used to study the risk of incident clinical AIDS and AIDS-related deaths among 813 HCV-negative women with HIV infection, 87 HCV-positive nonviremic women with HIV coinfection, and 407 HCV-positive viremic women with HIV coinfection (median follow-up time, 5...

Vertebral osteomyelitis, an infectious disease with vague manifestations, can be difficult to diagnose. Although vertebral osteomyelitis represents only 2-4% of bone infections, the consequences are often grave and disabling, even fatal, when untreated. A series of 23 cases is reported in which patient records were reviewed to determine the etiology and appropriateness of diagnosis and management. Information on treatment and follow-up after discharge was obtained from outpatient progress notes, records from subsequent hospital admissions, and telephone interviews of patients...

Four children who incurred perianal injuries as a result of a sexual assault were followed on a longitudinal basis to document the anatomical changes that ensued. The subjects, whose ages ranged from 4 to 8 years, were followed from 1 week to 14 months. They were examined in both supine and prone knee-chest positions and a 35-mm camera mounted on a colposcope was used to record their injuries. At the time of the initial examination, there were a variety of findings including erythema of the tissues, edema of the skin folds, localized venous engorgement, dilation of the external anal sphincter, and lacerations of different depths...

We compared the abilities of gamma interferon (IFN-gamma), tumor necrosis factor alpha (TNF-alpha), and sensitized murine lymph node lymphocytes to activate syngeneic murine peritoneal macrophages to inhibit the growth of intracellular Mycobacterium bovis BCG in vitro. IFN-gamma could activate antimycobacterial defense only when added to macrophage cultures prior to their infection with BCG. TNF-alpha was without any effect. In contrast, BCG-sensitized lymphocytes could induce antimycobacterial defenses when added after macrophages had been infected with BCG...

A highly attenuated respiratory syncytial virus (RSV) experimental vaccine, RSV ts-2, was sequentially evaluated in adults, seropositive children, and finally, fully susceptible seronegative children. The vaccine was administered intranasally in doses ranging from 10(5.2) to 10(6.3) PFU/ml. In both adults and children, the vaccine proved to be poorly infectious. Although poor infectivity would not have been predicted from tissue culture studies of RSV ts-2 growth, the human experience closely parallels the experience in a series of animal models, including the chimpanzee...

The sensitivity of an enzyme-linked immunosorbent assay (ELISA) to detect low levels of antibody to respiratory syncytial (RS) virus was compared with a tube dilution neutralization test (NEUT) on sera obtained from children who received a parenteral live RS virus vaccine. Among the children who developed antibody in response to live RS virus vaccine. ELISA was as sensitive as NEUT at detecting antibody increases. Some children who did not have detectable prevaccine ELISA antibody possessed NEUT antibody; these children were generally less than 12 months old, suggesting that they had low levels of maternal antibody...

A hospital-acquired outbreak of influenza-like illness that involved 29 patients during 4 weeks was detected in March 1980. The average age of the patients was 63 years. Eighteen of the 29 patients with symptoms had influenza B virus infection documented by virus isolations, fourfold or greater hemagglutination inhibition antibody increases, or both. The attack rate among all hospitalized inpatients was 20%. Absenteeism of the hospital staff because of influenza-like illnesses preceded the outbreak by several weeks, suggesting staff-to-patient transmission...

The sensitivity of an enzyme-linked immunosorbent assay (ELISA) for the detection of antibody to influenza B virus was compared with that of the hemagglutination inhibition test on acute- and convalescence-phase sera obtained from adults and children infected with influenza B virus. Two whole virus, tissue culture-grown antigen preparations were used in the ELISA, influenza B/West Virginia/81 and influenza B/Hong Kong/72. Four antigens were used in the hemagglutination inhibition test. These included the tissue culture-grown whole virus antigens that were used in the ELISA...

A live respiratory syncytial virus (RSV) vaccine administered parenterally was evaluated for efficacy in a double-blind, placebo-controlled field trial in 510 children six to 47 months of age. Among the 233 recipients of live RSV vaccine, 68 of 98 initially seronegative children (as determined by enzyme-linked immunosorbent assay) developed antibody to RSV; 25 of the 30 initially seronegative children who did not develop antibody were less than 12 months old, which suggested that very low levels of maternal antibody (undetectable by enzyme-linked immunosorbent assay) inhibited replication of the vaccine virus...

Forty-five university students with proved influenza A/USSR/77 H1N1 infection were randomly treated with either amantadine hydrochloride (14 students), rimantadine hydrochloride (19 students), or placebo (12 students). By 48 hours after initiation of therapy, amantadine and rimantadine recipients had significantly less fever and greater improvement compared with subjects given the placebo. Minor reversible CNS side effects at the end of the five-day course of therapy were observed in one third of the amantadine-treated subjects...

Forty-seven seronegative children were inoculated intranasally with influenza A/California/10/78 (H1N1) cold-recombinant vaccine (CR-37). Doses ranged from 10(3.2) to 10(7.2) TCID50 per child. The dose necessary to infect 50% of children (one HID50 ) was approximately 10(3.5) TCID50. Only two of eight children given 10(3.2) TCID50 became infected, and neither shed virus. The majority of children who were given 10(4.2), 10(5.2), 10(6.2), or 10(7.2) TCID50 of CR-37 became infected. Twenty-four of 39 children given greater than one HID50 of CR-37 shed vaccine virus...
