Item Effect of chemotherapy on pulmonary epithelial permeability in lung cancer(2000) Sayit E.; Aktoǧu S.; Ertay T.; Çapa G.; Erkmen G.; Özbilek E.; Büyükşirin M.; Durak H.The aim of this study is to investigate the effect of one-course chemotherapy on the pulmonary epithelial permeability. Eighteen patients (18 male; mean age: 59 ± 10 years) with lung cancer (11 non-small cell, 7 small cell) inhaled 40 mCi (1,480 MBq) 99mTc-diethylenetriaminepentaacetic acid (DTPA). Thirty images of 1-min duration were acquired from posterior projection. The first 7 min of the decay-corrected time activity curves were used to calculate lung clearance half-time. Clearance half-times of 99mTc-DTPA from the peripheral regions of the lungs were 42 ± 19 min before and 56 ± 34 min after chemotherapy (p = 0.009); from the central regions, clearance half-times were 112 ± 94 min before and 160 ± 125 min after chemotherapy (p = 0.005). This decrease in clearance rate might be related to decreasing mucociliary clearance rate due to the toxic effect of the chemotherapy regimen on cilia movement and/or mucus structure. 99mTc-DTPA radioaerosol study can be used to monitor the toxic effects of chemotherapy on the pulmonary epithelium and possibly on mucociliary function.

We also aimed to investigate the impact of nasal irrigation on mucociliary clearance with seawater gel compared with saline in this patient group. Methods: The study was performed in 100 consecutive adult individuals with a history of allergic rhinitis that was not controlled by anti-allergic drugs. Patients were assigned to receive seawater gel nasal spray for 10 days. The efficacy of treatment was assessed by means of total nasal symptom score and clinical findings. Results: A statistically significant difference was found between scores of ‘nasal discharge, nasal obstruction, sneezing, nasal itching—before and after treatment (p < 0.001). Clinical findings evaluation revealed a statistically significant decrease in lower turbinate colour rating and turbinate congestion at the end of treatment (p< 0.001). Saccharin transit time decreased from baseline in the seawater trials by 12% compared with a 4% decrease for saline. The difference between the percent changes was statistically significant (t = 2.177; p < 0.05). Conclusions: The present study provides evidence that a four times daily regimen of seawater gel can be an adjunctive therapy in the patient with allergic rhinitis. © 2010, SAGE Publications.
