Vitamin D supplementation for children with recurrent ear infections

I have noticed that much of the exciting human research on vitamin D originates in Turkey and Iran. I don’t know why, but researchers in those two countries keep published exciting clinical trials.

Take ear infections or acute otitis media (AOM). It is the most common infection that requires medical attention during childhood. AOM is the presence of fluid in the middle ear with acute signs of illness and middle ear inflammation such as bulging, cloudiness or redness of the eardrum. AOM is more common in the winter. It is unknown if it is latitudinal; that is, is it less common around the equator?

When I was a GP, it was common practice to put all children with AOM on antibiotics. Now, the concern about antibiotic resistance has changed that practice. Research shows that over 80% of ear infections resolve without antibiotics. That means, for example, that about 33 children must be treated with antibiotics to prevent one ruptured ear drum. Also, for every 14 children treated with antibiotics, one child has side effects to the antibiotic, such as vomiting, diarrhea or a rash. So it is now recommended to wait a few days before starting antibiotics and simply treat the ear pain.

In yet another exciting Turkish study, Doctor Atilla Cayir, working under the supervision of senior author Professor Behzat Ozkan at Ataturk University, published an open trial of vitamin D in 84 children with recurrent otitis media.

Cayir A, Turan MI, Ozkan O, Cayir Y, Kaya A, Davutoglu S, Ozkan B. Serum vitamin D levels in children with recurrent otitis media. Eur Arch Otorhinolaryngol. 2013 Mar 30.

They studied 79 children, all of whom had either four or more attacks of AOM in one year or three or more attacks in 6 months. Mean initial serum 25(OH)D levels in the study group was about 11 ng/mL, and levels were under 20 ng/mL were seen in 69% of the children, who were ages one to five.

Patients with low initial serum vitamin D levels (

All children were treated with antibiotics if needed, so standard treatment was used, not just vitamin D. In 1-year of follow-up of the 79 patients with recurrent otitis media, only one attack of AOM was detected in five patients and two attacks in two patients. Despite having had recurrent otitis media, no ear infections were observed in any of the remaining 72 patients over the year.

The authors concluded:

“These results support the view that vitamin D is a major immune-modulator and that deficiency may increase the incidence of upper respiratory infections such as otitis media. We believe that co-administration of supplementary vitamin D together with conventional treatments is appropriate in the management of upper respiratory infections such as recurrent otitis media.”

So, besides just waiting and treating the pain, practitioners now have precedent to give children with AOM vitamin D while they are waiting.

    of course better to give it in the first place before the infection to prevent it
    certainly more peds docs that I know seem to be buying into some of this thinking

    Dr. Cannell~

    Very interesting. I plan to share your information with a researcher at my institution.

    I am assuming that AOM can be caused by Streptococcus pneumoniae?

    Of course, you know I’m thinking if children were given adequate amounts of D3 all year long, then AOM would be a non-issue…

    But, that is only in my opinion. :)

    Be well,

    I am saddened to learn that there are indeed researchers in the US interested in studying Vitamin D supplementation for children with recurrent ear infections but NIH just won’t provide funding…. :(

    What will it take to turn the tide?
