The findings of this study indicate that allergen injection therapy with modified HDM extract is superior to placebo in allergic rhinitis therapy. The treatment was well tolerated and no serious drug-related AE were observed.
Immunotherapy with a modified slow-release birch pollen extract, administered in a single-strength preparation with a rapid dose increase, is safe and efficacious. IgG and IgG4 antibodies against native Bet v 1 are induced, which block basophil activation.
Nitrates decrease pulse pressure more than mean arterial pressure (MAP) and are advocated for the treatment of isolated systolic hypertension (ISH). Nitrates show drug tolerance during chronic treatment so an asymmetric dosing regimen may prevent loss of effect of nitrates. This study investigates the anti-hypertensive effect of isosorbide dinitrate (ISDN) given in a twice daily asymmetric dosing regimen in elderly patients with ISH.After a 6-week placebo run-in period, patients entered the double-blind study. Ten patients received placebo and 11 patients ISDN 20 mg b.i.d. for 8 weeks. This dose could be doubled once. Office systolic and diastolic blood pressures (SBP/DBP) and ambulatory BP were measured. Pulse pressure was calculated as SBP-DBP.Office pulse pressure was more reduced during ISDN
BackgroundSUBLIVAC FIX Birch (SUB-B) is a liquid oral preparation of Betula verrucosa pollen extract for the treatment of allergic rhinitis/rhinoconjuctivitis induced by birch pollen. The major allergen content of SUB-B and Staloral Birch (Stal-B) have been shown to be comparable. In order to compare the clinical efficacy and safety of both products, the present study was designed to investigate efficacy of treatment with SUB-B compared to Stal-B by means of reduction in allergy symptoms assessed by a titrated nasal provocation test (TNPT) in subjects suffering from IgE mediated allergy complaints triggered by birch pollen.MethodsA prospective, randomized, open, blinded endpoint (PROBE), controlled, single-centre study in 74 birch allergic adults was performed. Treatment consisted of either SUB-B (10,000 AUN/ml) or Stal-B (initial phase 10 I.R./ml and maintenance phase 300 I.R./ml) for 16–20 weeks at maintenance dose. The primary efficacy outcome was defined by the difference in change of the TNPT-threshold dose between the two treatment groups at baseline and after completion of treatment. Secondary outcomes included determination of birch pollen specific IgE and IgG levels, safety lab and ECG. During the first 30 days of treatment, subjects were requested to fill out a diary concerning compliance with study medication, occurrence of AEs and the use of concomitant medication.ResultsAnalysis of the primary efficacy parameter showed that the percentage of subjects showing a beneficial treatment effect was similar in both treatment groups, 33.3% for SUB-B vs. 31.4% for Stal-B in the intention to treat population. Evaluation of the immunologic response, showed that treatment with SUB-B and Stal-B induced similar increases (approximately 2 times) in IgE, IgG and IgG4 specific for Bet v 1.In total, 143 related adverse events (AEs) were reported. The majority of the AEs was of mild intensity. The same pattern of AEs was observed for both products. No clinically relevant changes in other safety parameters, such as safety laboratory parameters, vital signs, physical examination and ECGs were observed.ConclusionTaken together, treatment with both products was effective by means of reduction in allergic symptoms during a TNPT. In addition, safety analysis revealed a good tolerability of both SLIT extracts.
Once-daily nitrate therapy not only provides a better NYHA angina classification than multiple-dose therapy does, but also provides a better quality of life as estimated by improvement of mobility and distress indices, the most important indicators of quality of life in this category of patients.
We have compared, in an open randomized study, the effects of sodium nitroprusside (SNP) and urapidil on haemodynamic state and myocardial function and metabolism in two groups of patients undergoing elective coronary artery surgery. Sixty patients were allocated randomly to one of two groups: group SNP (n = 29) received SNP at an initial rate of 1-2 micrograms kg-1 min-1; group URA (n = 31) received one or more bolus injections of urapidil 25 mg and an i.v. infusion at an initial rate of 11-21 micrograms kg-1 min-1. Baseline measurements were obtained 10 min after introduction of an echotransducer into the oesophagus. Subsequently, vasodilator therapy was started in both groups. Infusion rates were adjusted to maintain systolic arterial pressure at 80-120% of baseline values (or mean arterial pressure < 100 mm Hg). Additional measurements were obtained 10 min after the start of vasodilator therapy and after sternotomy when the pericardium was opened. At each measuring time a complete haemodynamic profile, coronary sinus blood flow (CSBF) curves, transoesophageal echocardiographic images, and arterial and coronary venous blood samples were obtained. Arterial pressure was controlled adequately in both groups. After sternotomy, heart rate and cardiac index increased in both groups. At that time, there was a significant increase in myocardial oxygen consumption and CSBF in group URA (P < 0.05). However, the ratio between myocardial oxygen demand and oxygen supply remained unchanged and there was no difference in the number of ischaemic episodes between the groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
