In the treatment of serious infection by aminoglycoside antibiotics multiple daily treatment with netilmicin is considered to be the least toxic. Studies comparing netilmicin with gentamicin using the less toxic once-daily schedule are lacking. A randomized prospective study was designed to evaluate the efficacy and toxicity of once-daily netilmicin with gentamicin treatment in patients with serious infections. Consecutive patients with serious infections were randomized between gentamicin 4 mg/kg q24h iv or netilmicin 5.5 mg/kg q24h iv. Exclusion criteria were neutropenia or severe renal failure. A good clinical response was observed in 50 of the 54 evaluable patients (92.6%) treated with gentamicin and in 48/52 (92.3%) netilmicin treated patients. Nephrotoxicity developed in 5/72 (6.9%) gentamicin patients and in 10/69 (14.5%) treated with netilmicin. Audiometry was performed with high-frequency audiometry when possible; no significant differences were found between the two aminoglycosides. We conclude that with once-daily treatment no benefit of netilmicin over gentamicin regarding nephro- or ototoxicity could be demonstrated. 相似文献

During TB cytokines play a role in host defence. To determine the cytokine pattern during various disease stages of TB, serum levels of IL-12, interferon-gamma (IFN-γ), IL-4, IL-6 and IL-10 were measured in 81 patients with active TB, 15 patients during therapy and 26 patients after anti-tuberculous therapy as well as in 16 persons who had been in close contact with smear-positive TB and in 17 healthy controls. IFN-γ was elevated during active TB when compared with healthy controls, declining during and after treatment. IL-12 (p40 and p70) serum levels were not significantly higher in patients with active TB compared with any of the other groups. IL-4 levels were low in all groups. IL-6 and IL-10 serum levels were elevated in patients with active TB and during treatment. In patients with active TB serum levels of IFN-γ and IL-6 were higher in patients with fever, anorexia and malaise. IL-12 levels were higher in patients with a positive smear. Cytokine levels did not correlate with localization of TB (pulmonary versus extrapulmonary), or skin test positivity. Cytokines directing a Th1 response (IL-12) or a Th2 response (IL-4) were not elevated in sera of this large group of patients with pulmonary and extrapulmonary TB. In patients with active TB, cytokines that were elevated in serum were IFN-γ, IL-6 and IL-10. 相似文献

Mice from four different inbred strains were infected with live Mycobacterium tuberculosis and the immune response to M. tuberculosis was followed for 24 weeks, using Western blotting. Nearly all mice, irrespective of H-2 type, reacted with the 38-kDa protein band. Antibodies against this secreted 38-kDa protein were the first to appear, 4 weeks after infection. Thereafter the secreted 19-kDa protein and non-secreted antigens, such as the 65-kDa and 33-kDa proteins, were recognized. The immune response against the non-secreted antigens was influenced by the mouse strain. However, the 33-kDa protein band was recognized by all mouse strains after a second injection with live M. tuberculosis. The specificity of the antibodies was analysed in Western blot using sonicates of M. tuberculosis, M. kansasii, M. avium, M. terrae, M. gordonae and Escherichia coli. Antibodies against the 38-kDa and 33-kDa protein bands seemed to be specific for M. tuberculosis, while antibodies against the 19-kDa protein band showed limited cross-reactivity. Antibodies against the 65-kDa protein were strongly cross-reactive. These results suggest that the 38-kDa protein is secreted in vivo and, therefore, may be available to the humoral immune system at an early stage of infection. The non-secreted 33-kDa protein is only recognized by all mouse strains after prolonged contact with M. tuberculosis. 相似文献
