Recurrent respiratory infections, concurrent with recurrent urinary tract infections is a very common scenario because infection in each of these sites, lungs and urinary tract, is very common. For this reason, the occurrence of these two, together, does not mean that they are related in any way, including having a common cause. Were there a common cause, it would be a problem with your immune system but, unless you have also been prone to have infection elsewhere in your body, that is unlikely.
It is especially unlikely since there are at least two (maybe three) other reasons why you might have recurrent respiratory infection: 1) having once had a “big lung infection”, your lungs or even a part of one lung may have been permanently damaged, with the damaged lung less able to resist infection; 2) the dreadful reflux and regurgitation that could well be associated with recurrent aspiration of material from your stomach into your lungs. When this happens, the result can be chemical pneumonia and/or infectious pneumonia and, 3) that recurrent lung infection could occur as a result of acquired, non-infectious (even allergic) lung disease or an inherited (congenital) lung disease, for example Cystic Fibrosis. Yet another possibility is that you have had the misfortune to acquire a rather uncommon type of infectious lung disease, one not completely responsive to most conventional antibiotics.
Let’s just assume that the urinary tract infection, while a serious, debilitating problem, is unrelated. You should seek consultation with a Urologist or a Nephrologist to determine with certainty the organism(s) causing recurrent infection and determine if you might have any anatomical abnormalities in your urinary tract that could predispose you to infection.
As to the respiratory infection, there is a strong possibility that it is related to the gastroesophageal reflux (GERD). You mentioned having had endoscopy and being treated for H. Pylori. I assume that there was evidence on endoscopy of severe reflux. Did the GI specialist also address the GERD, with pharmacotherapy. You should be treated for an extended period of time with optimum reflux therapy. If that fails to control the reflux, you may be a candidate for surgery. If either were effective, you might experience the resolution and non-recurrence of your lung problems.
In the meantime, however you should also ask the lung specialist (Pulmonologist) in the respiratory to determine if you have any other lung disease that has developed independently of reflux induced lung disease. One you specifically might ask about is mycobacterial infection; specifically MAC disease, with or without bronchiectasis. Obtaining the CT scan of your lungs should be a priority, as it could well establish a diagnosis with reasonable certainty. The histamine challenge does not strike me as a priority, at this time..
You should ask that one of your physicians assume the role of coordinator of your care. The person who will bear responsibility for synthesizing all the available data and making the final recommendations to alleviate your problems.
Good luck
