I searched the National Library of Medicine's PubMed database at:
for the terms [ chronic cough dry ].
More than 100 articles were found on this topic. I've presented the
main ones in my answer, below, where chronic cough seemed to be the
main symptom under investigation. There were many cases of chronic
dry cough related to various occupational exposures of dust and spores
in the workplace, but I did not include these here, as I imagine this
would have been one of the first possibilities considered by the
In addition to citations, I've also included excerpts from the PubMed
abstracts. I can't post the full abstracts, since they are protected
by copyright, but you can see them yourself by reproducing the search
at the PubMed site.
Note, also, that many of the authors include contact information with
their abstracts, and if available, I've included this information as
I trust the information below fully answers your question.
However, please don't rate this answer until you have everything you

Noneosinophilic CD4 lymphocytic airway inflammation in menopausal
women with chronic dry cough.
Mund E, Christensson B, Gronneberg R, Larsson K.
The National Institute of Environmental Medicine, Division of Lung and
Allergy Research, Karolinska Institutet, SE-171 77, Stockholm, Sweden.
...Chronic dry cough without dyspnea and wheezing is a well-known
condition that is considered to be clinically overrepresented in
women. The etiology and morphology remain unknown in many cases
despite thorough investigations.
...CONCLUSIONS: HLA-DR-activated CD4+ lymphocytic airway inflammation
with a low number of eosinophils was identified in a group of
nonsmoking, nonatopic otherwise healthy women patients with dry cough
of life-long character. The disease appeared exclusively in connection

...Gastroesophageal reflux is known to cause chronic cough and is also
implicated in worsening of asthma.
...Our data showing that reflux events preceded coughing in most cases
and that treatment of GERD resulted in an improvement in different
outcome measures of asthma suggest that GERD worsens asthma, and its
treatment is of clinical importance to effectively manage these
A preliminary study of PEFR monitoring in patients with chronic cough.
Sano T, Ueda H, Bando H.
Department of Pulmonary Medicine, Tokushima Prefectural Central
Hospital, Kuramoto-cho 1-10-3, Tokushima, Tokushima 770-8539, Japan.
...It is important to make a differential diagnosis of cough variant
asthma in patients with chronic cough. To examine whether or not peak
expiratory flow rate (PEFR) is useful for the differential diagnosis
of cough variant asthma in such patients, diurnal variation rates of
PEFR were calculated in 23 patients who presented with dry cough
lasting four or more weeks and who showed no abnormalities on chest
...At week 3 of treatment with bronchodilators, only Group 3 showed a
significant decrease in PEFR diurnal variation rate from 25.7% to
10.1%. The cough score decreased significantly in Group 3 only.

Department of Respiratory Medicine, Belfast City Hospital, Northern
Ireland, UK. email@example.com
...Psychogenic cough occurs most commonly in patients under 18 years of age
...A large number of cough episodes were recorded during the day, but
during the time he was in bed there were very few episodes recorded.
This suggested a diagnosis of psychogenic cough, and he underwent
behavior modification therapy under the guidance of a clinical
psychologist, with good result.
...Objective cough monitoring may therefore improve the evaluation and
management of chronic cough.

Maingau Krankenhaus, Frankfurt a.M. firstname.lastname@example.org
...In non-smokers the underlying causes for chronic persistent cough
(CPC) e.g. chronic cough without diagnostic chest X-ray or pulmonary
function test--are usually as follows: several common upper airways
diseases, bronchial (cough type) asthma, gastrooesophageal reflux or
treatment with an ACE (angiotensin converting enzyme)--inhibitor. In
10% of CPC however the cause remains uncertain.
...(Induced) sputum staining should be added to the diagnostic

...Age related changes in the immune system have been studied
frequently but a possible relation to sex has not, to our knowledge,
previously been examined.

forms of dialysis for patients with end-stage renal disease. A few
case reports have suggested that cough is associated with PD
...The findings suggest that GERD and associated cough are more common
in PD patients than in HD patients, perhaps owing to increases in
intra-abdominal pressure from the peritoneal dialysate.
