In a double‐blind placebo‐controlled study, danazol, an attenuated androgen, was effective in reducing exercise‐induced weals in cholinergic urticaria. Danazol treatment also caused significant elevations of several protease inhibitors, particularly antichymotrypsin which has been reported previously to be low in cholinergic urticaria. 

Danazol and Ketotifen in a Refractory Cholinergic Urticaria: Case Report

A case of refractory cholinergic urticaria who had an adequate response to danazol and ketotifen is presented, thereby proving to be an effective therapy in patients who don ́t respond to conventional therapy and without access to biological treatment.

Cholinergic Urticaria and Exercise-Induced Anaphylaxis

Cholinergic urticaria is a common type of physical urticaria, and consists of small, short-lived urticarial weals occurring after a rise in core temperature. Exercise-induced anaphylaxis (EIA)

Cholinergic pruritus, erythema and urticaria: a disease spectrum responding to danazol

This case demonstrated a dramatic symptomatic response to danazol which has not previously been reported and strongly supports the view that all three syndromes are variations of the same disease.

Cholinergic Urticaria, an Effective and Safe “Off Label” Use of Dupilumab: A Case Report with Literature Review

The case of a 26-year-old man suffering from CholU for 3 years, unresponsive to standard treatment is reported, in which off-label therapy was undertaken with Dupilumab, 600 mg subcutaneous as a loading dose and then 300 mg every 15 days to assess the efficacy of the therapy.

Addition of lafutidine can improve disease activity and lead to better quality of life in refractory cholinergic urticaria unresponsive to histamine H1 antagonists

This data indicates that once the H1RA and H2RA antagonists are removed, the QoL, quality of life, and DLQI-J, Dermatology Life Quality Index, decreases, and the need for further research into these mechanisms is likely to be found.

Urticaria and angioedema: an overview.

Combined cold urticaria and cholinergic urticaria clinical characterization and laboratory findings

There was considerable variability, particularly in the cold urticaria which was of the common cold contact type in seven patients, of the generalized cold induced cholinergic type in two and in four patients the lesions induced by direct contact with ice were morphologically like cholinery, but appeared despite prior application of an acetyl choline antagonist.

In all types of urticaria it is important to work with the patient and try to eradicate the cause or inhibit the mediators giving the clinical signs to stop the progression of the disease.

Successful treatment of disabling cholinergic urticaria.

A 22-year-old African American U.S. sailor presented with an intermittent pruritic eruption precipitated by mild activity for the last 2 years, and was diagnosed with cholinergic urticaria, successfully controlled with a combination of cetirizine, montelukast, and propanolol.



Tests to establish the diagnosis in cholinergic urticaria

In patients with cholinergic urticaria, exercise proved the simplest, most effective diagnostic test and intradermal testing is not always reproducible in the same patient.

Treatment of Hereditary Angioedema with Danazol

Danazol effectively prevents attacks in hereditary angioedema and acts to correct the underlying biochemical abnormality and side effects were minimal.

Danazol effectively prevents attacks in hereditary angioedema and acts to correct the underlying biochemical abnormality and side effects were minimal.

Protease inhibitor profiles in urticaria and angio‐oedema

Patients with chronic urticaria/angio‐oedema showed a reduction in inter‐α trypsin inhibitor and a rise in C1 esterase inhibitor and the elevated levels of α2 macroglobulin in the three groups are probably due to differences in the mean age of these groups compared with the reference population.

Treatment of hereditary angio‐oedema by low dose attenuated androgens: disassociation of clinical response from levels of C1 esterase inhibitor and C4

Nine patients with hereditary angio‐oedema with a deficiency of C1 esterase inhibitor, have been treated with low dose attenuated androgenic drugs with complete control of their disease, and it is concluded that H. A. E. can be controlled in the absence of correction of the reduced levels of C 1 INH and C4.

Danazol-induced augmentation of serum alpha 1-antitrypsin levels in individuals with marked deficiency of this antiprotease.

It is demonstrated that serum alpha1-antitrypsin levels can be augmented by danazol therapy in PiZ individuals as well as those heterozygotes with severe deficiency of alpha 1-ant itypsin.
