Rosacea and Antibiotic Resistance | Arthritis Information

Share
 

-- Using antibiotics to treat rosacea -- a regimen that has no basis in evidence but a long history in daily clinical practice -- has contributed to antibiotic resistance, according to a review of the latest evidence.

The primary suspects in this case are the tetracyclines, particularly doxycycline, explained Hilary E. Baldwin, M.D., an associate professor and vice-chair of the department of dermatology at SUNYDownstate Medical Center in New York.

And, in a surprising finding, resistance to doxycycline can occur in a few days, with resistant bacteria in abundance after just seven days of treatment with 100 mg doxycyline daily, she said.

Dr. Baldwin reviewed rosacea treatments during a presentation at the Skin Disease Education Foundation Hawaii Dermatology Seminar.

She said that antibiotics became a standard rosacea treatment because of the mistaken belief that "the etiology of rosacea was bacterial. But the best current evidence is that microbes are not involved."

Importantly, she said, "no antibiotic is FDA approved for treatment of rosacea."

Yet, antibiotics continue to be a standard course because they "appear to be effective for treatment of papulopustular rosacea," she said.

But tetracyclines work, Dr. Baldwin explained, not because of their antibiotic properties but because "they have anti-inflammatory activity."

Specifically, tetracyclines are involved in downregulation of proinflammatory cytokines, inhibition of angiogenesis, inhibition of neutrophil chemotaxis, inhibition of nitric oxide activity, and suppression of neutrophil-derived production of reactive oxygen species -- all of which helps them take the red out of rosacea.

And if one reduces the doxycycline dose to 50 mg or less a day, "you have an anti-inflammatory dose, not an antibiotic dose."

But she warned that "giving 100 mg every other day, is not an anti-inflammatory dose."

The 100 mg every other day actually promotes antibiotic resistance because it is starting and stopping an antibiotic regimen.

Dr. Baldwin disclosed financial relationships with Allergan, Galderma, Glaxo Smith-Kline, Ortho-Neutrogena, Medicis, Ranbaxy, sanofi-aventis, and Steifel.

"Many doctors are also afraid that long-term use of antibiotics will  
lead to resistance. In reality this isn’t an issue. When antibiotics  
are pulsed, the concentration of the antibiotic in the tissues is  
always changing and there are different levels of antibiotic in the  
body at any one point in time. Because the level of antibiotic is  
never constant, it is impossible for bacteria to develop resistance  
mechanisms. The effectiveness of pulsing a substance in order to  
eliminate the ability of a pathogen to develop resistance has been  
demonstrated with pesticides. It has been found that disseminating  
pesticides in spurts rather than in a continuous fashion keeps the  
pathogens in crops from becoming resistant to the chemicals in the  
pesticide. Plus, we continue to find that when patients take  
minocycline, it continues to generate strong changes in  
immunopathology even after they have been taking the drug for many  
years."


 
Indications

It is primarily used to treat acne and other skin infections as well as lyme disease as the one pill twice daily 100 mg dosage is far easier for patients than the four times a day required with tetracycline or oxytetracycline.

Although minocycline's broader spectrum of activity, compared to other members of the group, includes activity against Neisseria meningitidis, its use as a prophylaxis is no longer recommended because of side effects (dizziness and vertigo).


It may be used to treat certain strains of MRSA infection and disease caused by drug resistant Acinetobacter.


Minocycline is recognized as a DMARDS (Disease-Modifying Antirheumatic Drug) by the American College of Rheumatology, which recommends its use as a treatment for mild rheumatoid arthritis.

For other uses of minocycline see Tetracycline antibiotics and oxytetracycline as the uses are much the same between Tetracyclines with only minor exceptions.

Is that all you have to say?

Because I look at you as a AP pimp, er pip.

Isn't it great that they work!  As you said,  "it seems clear".

I hadn't opened this thread about rosacea and wasn't sure why it was posted on an RA board, but now I take it that it was to support AP. 

Is there a link to the article, Lynn?  I didn't see posted what the dr. recommends for rosacea in place of doxycycline.
