My mother (51/F) had SOB and fever, cough etc. PFT showed probable restriction. SpO2 95 (at rest) 79 (after 6MWT). HRCT showed inter and intra lobular septal thickening, more marked at bases and few reactive mediastinal lymph nodes. Rest clear. The doc prescribed deriphyllin retard for 4 days and now DEC along with it, as her eosinophilia was high at around 15%(blood test done one month before her visit to the doc). Now her absolute eosinophilia count (EDTA) is normal 176 (normal range: 40-440). This level after 4 days of deriphyllin retard and 1 day of DEC. My Question is should she continue with DEC now that her eos. Is normal. Does DEC treat something else too? Will it be okay continuing current medication for next 10 days as the doc has prescribed?
