    Notes: The objective of this study was to compare the efficacy and safety of a pure powder formulation of budesonide, delivered from a new multi-dose dispenser for nasal drug application, with the commercially available budesonide pressurized aerosol, and with placebo. Of 116 patients with grass pollen-induced allergic rhinitis, 112 finished the study, which comprised a 4-week treatment period, preceded by a 1-week run-in period. The patients were randomized to four parallel treatment groups: budesonide powder 400 Hg daily; budesonide powder 800 μg daily; budesonide aerosol 400 μg daily; and placebo Powder. Treatment was given once daily in the morning. The study was double-blind regarding comparison between budesonide powder and Placebo. Assessment of efficacy, made by comparing mean scores of nasal symptoms and use of rescue medication, showed equal efficacy of all three budesonide groups compared with placebo. There were no differences between budesonide-and placebo-treated groups with regard to side effects. Budesonide treatment had no demonstrable effect on the HPA-axis assessed by measurement of 24-h urine cortisol. We conclude that budesonide, delivered as pure powder from a multi-dose dispenser, is effective and safe for the treatment of seasonal allergic rhinitis. This new formulation is a good alternative to the commercially available preparations, as it does not contain carrier gas, preservatives or lubricants.

    Notes: Histamine challenge was performed in 19 patients using two nebulizers (PARI and Wright) and FEV1 and PEF were measured to determine PCOT histamine. FEV1 and PEF gave identical PC20 histamine values. The PARI nebulizer gave PC20 histamine values that were 2.5 doubling concentrations lower than the Wright nebulizer. The reproducibility of histamine challenge with the PARI nebulizer1 was studied in 15 patients and the results suggested that the challenge was reproducible within one doubling concentration of histamine.

    Notes: Glucorticoid sprays are increasingly used for the treatment of allergic rhinitis and asthma. This therapy is highly effective, and side effects are few and mild. It was the aim of the present study to evaluate a physiological nasal inhalation technique, which results in airway deposition of the steroid molecule similar to that of inhaled allergen particles. Thirty adults with grass pollen-induced rhinitis and asthma inhaled the steroid molectile budesonide through the nose from a pressurized aerosol attached to a spacer device. Compared with inhalation of placebo, the treatment resulted in a significant reduction of nasal symptoms (P=0.005), of bronchial symptoms (P=0.005), bat not of eye symptoms. In addition, nasal peak inspiratory flow (P=0.0003) and oral peak expiratory flow (P=0.02) increased. There was no difference between budesonide and placebo with regard to local side effects, such as nose bleeding, hoarseness, and irritation in mouth and throat. It is concluded that nasal inhalation of a steroid from a spacer offers effective therapy of pollen rhinitis and asthma without significant local side effects. This therapeutic modality may have advantages over the ordinarily used nasal and bronchial spray treatment in patients with both rhinitis and asthma, especially when conventionel spray therapy is associated with local side effects.

    Notes: Methylprednisolone pulse therapy (MPPT) has been shown to possess a long-lasting effect in other immune-inflammatory diseases without the well-known side effects caused by long-term treatment with glucocorticosteroids. In an attempt to reduce the long-term use of oral steroids in asthmatics, we conducted this double-blind, double-dummy study to compare the use of MPPT (1 g of methylprednisolone intravenously) (8 patients) with a short course of oral prednisolone (10 patients) in asthmatics presenting with acute severe asthma. Both treatments were effective in relieving the acute attack of asthma. The MPPT-treated patients did not show a faster resolution than did the orally treated group. No patients needed assisted ventilation, and no deaths occurred. One week after the treatment FEV1 tended to decrease in the methylprednisolone group compared with the oral prednisolone group (P = 0.06). The patients initially receiving MPPT needed supplementary prednisolone earlier and in higher doses than did the patients receiving oral prednisolone as initial treatment. At the end of the 12 weeks' study period, the groups reached identical FEV1. In conclusion, we did not find intravenous methylprednisolone superior to oral prednisolone in the treatment of acute attacks of severe asthma, but methylprednisolone pulse therapy had a shorter duration as regards protection against future asthma attacks.

    Notes: The immunomodulatory drug isoprinosine has been found to delay the occurrence of opportunistic infections in HIV-infected individuals. To elucidate the mechanism of action, eight HIV-positive, healthy patients were treated with isoprinosine, 3 g/day for 28 days; six patients received no treatment but were examined in parallel, and two patients were withdrawn. All patients had blood collected just before the start as well as on days 14 and 28 of isoprinosine treatment.Isoprinosine significantly enhanced the lymphoproliferative response after stimulation with phytohaemagglutinin (PHA) and purified derivative of tuberculin (PPD), while isoprinosine had no effect on the following immune parameters: the expression of surface markers on blood mononuclear cells including CD2, CD3, CD4, CD8, CD14, CD19, CD20, CD25, leu-8, and HLA-DR. Furthermore isoprinosine did not influence the ability of interleukin 2 (IL-2) to stimulate the proliferation of lymphocytes or the natural killer (NK) cell activity either unstimulated or stimulated in vitro with alpha interferon (IFN-α), IL-2. or indomethacin. Neither did isoprinosine affect the in vitro production of (IL-1) α or β, IL-2, IL-6. or tumour necrosis factor (TNF).

    Notes: Leucocyte expression of the urokinase receptor [urokinase-type plasminogen activator receptor (uPAR)] is regulated by inflammatory mediators. This study investigated the in vivo effect of endotoxin, interleukin (IL)-6 and tumour necrosis factor (TNF)-α on uPAR-release in vivo and in vitro in humans. Healthy subjects received intravenous endotoxin injection [high-dose, 2 ng/kg (n = 8) and low-dose, 0.06 ng/kg (n = 7)], coadministration of 0.06 ng/kg endotoxin and 3 h recombinant human (rh)IL-6 infusion (n = 7) or 3 h infusion of rhIL-6 (n = 6), rhTNF-α (n = 6) or NaCl (n = 5). Soluble uPAR (suPAR) was measured by enzyme-linked immunosorbent assay in plasma and supernatants from unstimulated and phytohaemagglutinin and lipopolysaccharide-stimulated peripheral blood mononuclear cell (PBMC) cultures incubated for 24 h. The spontaneous and stimulated uPAR-release from PBMC cultures was enhanced 5 h after low-dose endotoxin (both P 〈 0.05), but coadministration of rhIL-6 during low-dose endotoxaemia abolished this enhanced uPAR release. High-dose endotoxin increased plasma suPAR levels (P 〈 0.001) whereas low-dose endotoxin, rhIL-6 or TNF-α did not influence uPAR release in vivo to such degree that a systemic effect on the plasma suPAR level was detectable. Even subclinical doses of endotoxin in vivo enhance the capacity of PBMC to release uPAR after incubation in vitro. The inhibitory effect of IL-6 on endotoxin-mediated uPAR-release in vitro suggests that IL-6 has anti-inflammatory effects on endotoxin-mediated inflammation.

    Notes: The purpose of the study was to examine how immune parameters related to non-major histocompatibility complex (MHC) restricted cytotoxicity changed with respect to progression and duration of human immunodeficiency virus (HIV) infection. Forty-one HIV seropositive subjects with a known time for seroconversion were included. The major finding was that a low percentage and number of natural killer (NK) cells were found in the group who had a rapid progression to acquired immune deficiency syndrome (AIDS) (less than 70 months following seroconversion) compared with those progressing more slowly to AIDS (more than 70 months following seroconversion). Furthermore, a significant correlation was found between the number of months from seroconversion to the diagnosis of AIDS and percentages of CD16+ cells (rs = 0.811, P 〈 0.01), CD56+ cells (rs= 0.647, P 〈 0.05), and CD16+CD56+ cells (rs= 0.839, P 〈 0.01) as well as the concentration of CD16+CD56+ cells in the blood (rs= 0.699, P 〈 0.05). No differences were found in percentages and concentrations of NK cell subsets between subjects with a long history (more than 6 years) versus a short history (less than 6 years) of HIV infection without AIDS. Furthermore, no negative correlations were found between the concentration of any NK subsets and the number of months since seroconversion in HIV seropositive individuals without AIDS. The total concentration of CD16+, CD56+, and CD16+ CD56+ cells was lower in the group of HIV seropositive subjects compared with HIV seronegative subjects (age and sex matched), and the concentration of CD16+ cells was lower in those with AIDS than in those without AIDS. In conclusion, low concentration of NK cells in the blood was associated with a more rapid disease progression, indicating that defective non-MHC restricted cytotoxicity may be associated with HIV disease progression.

    Notes: The present in vitro study was conducted to examine how glutamine influences the lymphocyte function. Glutamine had no effect on the production of interleukin-1β, interleukin-6 or tumour necrosis factor-α, but influenced the production of interleukin-2 and interferon-γ. Glutamate, leucine, isoleucine and valine (substrates for glutamine production), or the combination of glutamate and leucine, did not influence the lymphocyte proliferative response or the cytokine production. In conclusion, glutamine influenced the production of some T-cell-derived cytokines, and is thereby important for optimal lymphocyte proliferation. Furthermore, the results show that lymphocytes are not capable of producing glutamine.

    Reduced Release of Intact and Cleaved Urokinase Receptor in Stimulated Whole-Blood Cultures from Human Immunodeficiency Virus-1-Infected Patients (2005)

    Notes: The blood levels of the soluble forms of the urokinase receptor (suPAR) are increased in human immunodeficiency virus (HIV)-1-infected patients. This study investigated whether the release of urokinase-type plasminogen activator receptor (uPAR) in whole-blood cultures was affected by HIV infection. The release of different uPAR forms in whole-blood cultures incubated 24 h with or without phytohemagglutinin and lipopolysaccharide was analysed in 47 HIV patients and 19 controls. suPAR was measured by enzyme-linked immunosorbent assay (ELISA) (bulk-suPAR) and three different time-resolved fluorescence immunoassays measuring three-domain suPAR [suPAR(I–III)], three- and two-domain suPAR [suPAR(I–III) + suPAR(II–III)] and one-domain suPAR [suPAR(I)]. The uPAR release was correlated to leucocyte subpopulations and plasma levels of suPAR. The stimulated net whole-blood culture release of bulk-uPAR, uPAR(I–III), uPAR(II–III) and uPAR(I) was reduced in HIV patients (all P 〈 0.01), whereas the spontaneous bulk-uPAR and uPAR(I–III) release was increased in HIV patients (both P 〈 0.05). The stimulated uPAR release in whole-blood cultures correlated well to leucocytes and circulating suPAR levels in controls, whereas the correlation was weaker to leucocytes and nonexisting to circulating suPAR levels in HIV patients. These findings demonstrate that HIV infection affects stimulated and spontaneous uPAR release in whole-blood cultures. Given that high blood levels of suPAR in HIV patients are linked to immune activation, the perturbations in uPAR release in whole-blood cultures from HIV patients may also reflect immune activation.

    Notes: Background Seasonal allergic rhinitis constitutes an excellent in vivo model of an allergic mucosal inflammatory reaction. This offers the opportunity of studying the fundamentals of allergic inflammation in addition to improvement of knowledge on the basal pathophysiological mechanisms of the disease. So far, monitoring methods of disease activity and treatment efficacy have mainly been based upon subjective assessments, illustrating the impact of introducing reliable objective methods.Objective To investigate the allergic inflammatory reaction of seasonal rhinitis through different objective methods and evaluate these as indicators of disease activity and treatment efficacy.Methods Functional parameters, i.e. acoustic rhinometry and nasal metacholine challenge, and biological markers, i.e. blood eosinophil count, eosinophil cationic protein in serum (s-ECP) and nasal lavage fluid (n-ECP), were assessed before and at peak pollen season in 27 patients with grass pollen induced rhinitis. Patients were randomized to either nasal corticosteroid or placebo treatment and recorded nasal symptom scores.Results Acoustic rhinometry revealed a significant difference in favour of steroid treatment (P 〈 0.05) comparing nasal volumes before and during season. This difference primarily relied upon a decrease in the placebo group (P= 0.05). A reduction from baseline of s-ECP in the steroid group (P 〈 0.01) was obtained. N-ECP demonstrated a difference between treatment groups, although not significant. Symptom scores increased in all patients during the pollen season, although this was only significant in the placebo treated patients (P 〈 0.01). The remaining methods applied did not demonstrate further differences, either within or between treatment groups.Conclusion Our results demonstrate acoustic rhinometry to be a sensitive and objective method of assessment of nasal obstruction. Furthemore, acoustic rhinometry and s-ECP reflect the impact of nasal steroid therapy on seasonal allergic rhinitis.
