    Notes: Background The combination of montelukast (ML) and loratadine (LT) has previously been shown to be superior to either drug alone in managing seasonal allergic rhinitis (SAR), whilst fexofenadine (FEX) has been shown to be better than LT as monotherapy.Objectives We wished to compare ML + LT vs. FEX alone for effects on daily measurements (am/pm) of peak inspiratory flow (PIF) and symptoms.Methods Thirty-seven patients with SAR (skin prick positive to grass pollen) were randomised into a single-blind, double-dummy placebo (PL)-controlled cross-over study during the grass pollen season, comparing 2 weeks of once daily treatment with (a) 120 mg FEX or (b) 10 mg ML + 10 mg LT. There was a 7–10 day placebo run-in and washout prior to each randomised treatment. The average of am/pm PIF (the primary outcome variable) was analysed. Patients recorded their symptom scores (from 0 to 3) twice daily, for nasal blockage, discharge, itching and sneezing with; total eye symptoms, ocular cromoglycate use, and daily activity. The total nasal symptom score was calculated as a composite (out of 24).Results There were no significant differences between baselines after the run-in and washout placebos for any variables. There were significant (P 〈 0.05, Bonferroni) improvements in all symptoms and PIF compared to pooled placebo with both treatments for all end-points, but no differences between the two treatment regimes (as means and within-treatment 95% confidence intervals): PIF: PL 102 (98–107), FEX 111 (107–116), ML + LT 113 (109–118); total nasal symptoms: PL 7.4 (6.7–2.0), FEX 5.0 (4.3–5.7), ML + LT 4.0 (3.3–4.7).Conclusions Once daily FEX as monotherapy was equally effective as the combination of once daily ML + LT in improving nasal peak flow and controlling symptoms in SAR. Further studies are indicated to assess whether ML confers additional benefits to FEX in SAR.

    Notes: Summary There is conflicting data in the literature as to whether subsensitivity of in-vivo β2-adrenoceptor (β2-AR) responses in patients with asthma is due to an endogenous defect of β2-AR or an effect of exogenous β2-agonist therapy. The purpose of the study was to compare in-vitro parameters of lymphocyte β2-AR function in eight age and sex matched normal [FEV1, 98 (2) % predicted] volunteers and asthmatic [FEV1, 60 (5) % predicted] subjects. The asthmatic group were washed out for 4 weeks by substituting inhaled β2-agonist therapy with ipratropium bromide, in order to exclude possible exogenous effects of β2-agonist exposure. Receptor binding affinity (Kd) and density (Bmax) were evaluated using (-)125I-iodocyanopindolol and maximal cAMP response (Emax) was assayed following stimulation with isoprenaline (10−4M). No significant differences were found between the normal and asthmatic group for Kd (pmol·l−1): 9.65 vs 10.2, Bmax (fmol/106 cells): 1.9 vs 1.6, or Emax (pmol/106 cells): 4.24 vs 4.85. Thus, parameters of β2-AR function are unaltered in asthmatic patients who have not been exposed to β2-agonists, suggesting that asthma is not associated with an endogenous defect of β2-AR.

    Notes: Summary The effects of human ANF 99-126 on the aldosterone and cortisol responses to ACTH infusion were studied in 8 normal volunteers. ACTH infusion caused a significant rise in aldosterone and cortisol on each study day. On the day that ANF was concomitantly infused the aldoster-one, but not the cortisol, response to ACTH was significantly attenuated. These results show that a pharmacological dose of ANF selectively inhibits ACTH mediated mineralocorticoid as opposed to glucocorticoid release in man. These results support in vitro and in vivo findings from animal experiments. These findings also compliment previous studies showing that ANF inhibits ANG II stimulated aldosterone release in normal subjects.
