RT Journal Article SR Electronic T1 Pulmonary function in tropical eosinophilia before and after treatment with diethylcarbamazine. JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 574 OP 577 DO 10.1136/thx.30.5.574 VO 30 IS 5 A1 M S Nesarajah YR 1975 UL http://thorax.bmj.com/content/30/5/574.abstract AB Spirometric and lung volume measurements were carried out before and after treatment with diethylcarbamazine in 19 patients with tropical eosinophilia. The total lung capacity and vital capacity returned to or nearly to normal while the FEV1 and PEFR, though improved, tended to remain below normal, indicating some residual airways obstruction especially in patients whose treatment began more than one month from the onset of symptoms. The time taken for the pulmonary function to return to normal with treatment was found to be much longer than for the clinical and haematological response.
