Investigating the effectiveness of the Trigonella foenum-graecum L. (fenugreek) seeds in mild asthma: a randomized controlled trial.

BACKGROUND: Asthma is one of the important chronic diseases. The asthma prevalence is increasing in last decades. Despite the presence of good controller drugs like corticosteroids, about 60% of asthmatic patients use alternative medicine. This study was done to determine the effectiveness of Tregonella foenum graceum (fenugreek) seeds in mild asthma. METHODS: It is a double blind trial with placebo effect. One of the ancient prescriptions from Persian Medicine was selected. The participants were divided to three groups randomly. On group received fenugreek syrup one received honey syrup and the third received placebo. Duration of treatment was 4 weeks. Quality of life, Lung function tests and IL-4 levels were evaluated before and after treatment. RESULTS: From 90 participants to study 79 completed the process. After study there was significant increase in quality of the life and lung function tests and IL-4 levels in fenugreek and honey groups. CONCLUSION: FEV1 level was improved more than 10% in fenugreek group. Treatment was well tolerated. No serious side effects were reported during the study. The aqueous extract of fenugreek seeds appears to be effective and safe in treatment of mild asthma.Trial registration The study was recorded with the Iranian Registry of Clinical trials [http://www.irci.ir], registration code: IRCT2016011325991N1.

Direct detection of Pseudomonas aeruginosa from patients with healthcare associated pneumonia by real time PCR.

Using oprL sequences, a TaqMan real time PCR was developed and used for quantitative detection of Pseudomonas aeruginosa from 99 broncoalveolar lavage and 11 sputum specimens collected from patients with health care associated pneumonia. All specimens were cultured on appropriate media to isolate bacteria. Twenty five specimens were positive by both methods. Polymicrobial infections were found in 13 specimens. Amplification of oprL in serial dilutions ranged from 10(9)CFU/ml to 10(2)CFU/ml. Standard curve of duplicated every dilution had slope 3.25±0.1 and R(2)>0.99 with SD 0.1. Our real time PCR assay showed high sensitivity (100%) and specificity (98.85%). This technique could detect and enumerate 100 bacteria directly from clinical specimens and showed that the threshold is 10(3)CFU/ml in cases with clinical symptoms. Our method can be used for quantitative detection of P. aeruginosa from BAL and sputum specimens in 1h and 10min.
