thanks for asking your query i completely understand your problem for recurrent upper and lower respi tract infections you can have a 14 day course of antibiotics such as cefexime after asking your pulmonologist and regarding aspergillosis or abpa , actual treatment is a long term course of steroid tablets like predinisolone and leukotreine antagonists like monteleukast . all these are standard treatments but as per your history you have some immunocompromised state. you should consult a pulmonologist and investigate about wat type of immunocompromised state you have and how it can be corrected. dont panic abpa is a treatable disease , thing is treatment is for long duration and you have to comply to it . as i said consult a pulmonologist and you have to take your treatment under supervision as you said you have immunocompromised state thanks/ regards feel free to ask more questions may god bless u with good health
