Abstract
Otitis
media (OM) has numerous presentations in children. Together with
conventional medical therapies aimed to prevent and/or treat OM, a
rising number of complementary and alternative medicine (CAM) treatment
options can be offered. Since OM is common in children, parents may ask
healthcare professionals about possible CAM therapies. Many physicians
feel that their knowledge is limited regarding these therapies, and that
they desire some information. Therefore, we conducted a literature
review of CAM therapies for OM, taking into account that many of these
treatments, their validity and efficacy and have not been scientifically
demonstrated.
We performed a search in MEDLINE
(accessed via PubMed) using the following terms: “CAM” in conjunction
with “OM” and “children. Retrieved publications regarding treatment of
OM in children which included these terms included randomized controlled
trials, prospective/retrospective studies, and case studies.
The
following CAM options for OM treatment in children were considered:
acupuncture, homeopathy, herbal medicine/phytotherapy, osteopathy,
chiropractic, xylitol, ear candling, vitamin D supplement, and systemic
and topical probiotics. We reviewed each treatment and described the
level of scientific evidence of the relevant publications.
The
therapeutic approaches commonly associated with CAM are usually
conservative, and do not include drugs or surgery. Currently, CAM is not
considered by physicians a potential treatment of OM, as there is
limited supporting evidence. Further studies are warranted in order to
evaluate the potential value of CAM therapies for OM.
INTRODUCTION
Alternative
medicine is any practice claiming to possess the healing effects of
conventional medicine, but does not originate from evidence-based
scientific methods.1
It consists of a range of healthcare practices, products, and
therapies, ranging from being biologically plausible but not
scientifically tested, to being directly contradicted by evidence, or
even harmful or toxic. Complementary medicine is an alternative medicine
used in conjunction with conventional medicine, in a belief that it may
be synergistic.2
Complementary
and alternative medicine (CAM) is popular worldwide. Expenditure on CAM
experts visits and therapies in children is constantly growing.3
The main reasons for choosing CAM therapies are that CAM attempts to
provide a personalized approach to the sick child, parents’
disappointment with conventional medicine, personal or professional
recommendations, and parents’ previous experience. Despite significant
expenditures on testing CAM, including $124 million spent by the U.S.
Government in 2014,4 <5% of therapies were tested in children. Only few have shown effectiveness, leading physicians to question their efficacy.
Otitis
media (OM) includes a spectrum of diseases, which range from middle ear
fluid collection (OM with effusion, OME), to purulent fluid behind the
tympanic membrane (acute otitis media, AOM) and recurrent AOM (RAOM).
Many countries published different guidelines for OM treatment.
Currently, CAM therapies are either ignored or discouraged those
guidelines, even in countries where CAM is popular.5,6
Due
to OM high prevalence, physicians may be asked their opinion regarding
CAM therapies for pediatric OM, but they may often feel uncomfortable
advising parents due to lack of knowledge. In order to fill the
knowledge gap, we sought to review scientifically the knowledge gained
regarding CAM therapies for pediatric OM.
METHODS
We
used the terms “complementary medicine” and/or “alternative medicine”
in conjunction with “otitis media” and “children” in our MEDLINE search
(accessed via PubMed), and The Cochrane Library, from January 1980 to
September 2015. Randomized controlled trials (RCTs),
prospective/retrospective studies, and case reports in the English
language reporting on any CAM treatment in the context of pediatric OM
were included. If the article was not published in English, we relied on
the abstract as it appeared in the search engine. No authors declared
conflict of interest. Ethics committee approval was not requested
because it is not needed for systematic reviews of the literature
according to the Israeli and Italian laws.
RESULTS
Table Table11 summarizes the evidence gathered regarding the efficacy of different CAM treatment options for OM in children.
ACUPUNCTURE
Acupuncture
(needle puncturing) derives from traditional Chinese medicine and
involves inserting thin needles into the body at specific points.2
According to acupuncture, the body's energy force, chi (qi),
differentiates a corpse from a live human being. Acupuncture balances
and enhances chi to bring the body into a healthy state. The auricle
harbors numerous locations which are punctured for the treatment of many
diseases. Yet, 4 specific locations around the external canal are
believed to be the primary gatekeepers of the ear's energy, and they are
punctured in OM cases (Figure (Figure1).1).
There is little understanding why acupuncture may be beneficial, but it
is suggested that it has immunomodulatory properties that may play a
role in clearance of middle ear fluid.7
Key
locations for relieving ear pain in otitis media (OM) in an ear model:
(1) tragus, (2) base of the triangular fossa, (3) mid-helix, and (4)
antitragus.
Few studies concerning acupuncture for the treatment of OM in humans have only been published, but not in English.8–10
In 2 studies in canines, acupuncture was evaluated for the treatment of
recurrent otitis episodes. At first, animals with otitis were
randomized to receive conventional therapy, and either sham acupuncture
or “directed” acupuncture. Over the subsequent year, majority of the
dogs in the acupuncture group were otitis-free.11 The same authors reported that acupuncture may enhance the effect of antibiotic treatment for otitis in dogs.12
However, since the reported type of otitis is unclear, and given that
otitis externa usually affects canines, these conclusions may not be
attributable to humans.
HOMEOPATHY
Homeopathy
is based on the “like cures like” (similia similibus curentur)
doctrine: a substance that causes the symptoms of a disease in healthy
people would cure similar symptoms in sick people.1
Homeopaths generally prescribe remedies that have a “symptom picture,”
which they consider most closely equates to the constellation of the
patient's symptoms.
Most remedies combine an extract of
a natural substance, combined with a synthetic compound, which enhances
the therapeutic effect. A list of homeopathic remedies for OM treatment
is shown in Table Table22.
Research
into the effects of homeopathic treatment for OM is scant, and its
quality is limited. The first prospective cohort study comparing the use
of homeopathy for RAOM with conventional treatment was reported in
1997: 71% children from the homeopathic group had fewer OM episodes,
whereas 57% of the conventional group received treatment for OM.13 The unequal numbers between the homeopathic (103) and conventional group,14
and the absence of randomization considerably weakened the study's
validity. Two subsequent RCTs also showed promising results. The 1st
compared homeopathic and placebo for AOM in 75 children from Seattle who
presented with otalgia and tympanic membrane bulging of ≤36 hours
duration. A significant decrease in symptoms at 24 and 64 hours after
treatment were observed in the homeopathy group, and there were fewer
treatment failures in this group after 5 days, 2 weeks, and 6 weeks, but
they were not statistically significant.15
In another study from Jaipur, India, 81 young children with AOM were
randomly assigned to conventional (antipyretics, analgesics) and
homeopathy treatment groups. Nearly all children in the conventional
group eventually required antibiotics, compared to none in the
homeopathy group. The number of children experiencing “cure” suggested
that early homeopathic treatment could have advantages beyond a “watch
and wait” policy.16 The results of these trials are promising.
In
an RCT which compared homeopathic and conventional treatment in 33
children diagnosed with OME, 75% in the homeopathic group had a normal
tympanogram after 12 months, compared to 31% in the conventional group. A
higher proportion of children receiving homeopathic treatment had a
hearing loss <20 dB at follow-up, though the difference was not
statistically significant. In another prospective observational study of
230 children receiving homeopathic treatment for AOM, pain control was
achieved in ∼40% of patients after 6 hours, and in further 33% of
patients after 12 hours.17 The rate of AOM resolution in the homeopathic group was 2.4 times faster, without complications.
According
to homeopathy, there is an “effectiveness gap” in the conventional
approach for OM. Thus, it is argued that homeopathy should be integrated
into the treatment strategy for OM.18
Nevertheless, other authors who published in esteemed journals
considered homeopathy to be no more effective than placebo, and
essentially dismissed the need for further RCTs.19,20
Herbal Medicine/Phytotherapy
Herbal
medicine and homeopathy are interchangeable practiced together and
sometimes confused. Herbal medicine is the use of plants for medicinal
purposes.1 Herbal products are generally considered as safe, though efficacy is unclear and side effects may vary.
Phytotherapy
is the study of the use of extracts of natural origin as medicines or
health-promoting agents. Although standard pharmacology isolates an
active compound from a given plant, phytotherapy aims to preserve the
complexity of substances from a given plant. Phytotherapy avoids mixing
plant ingredients with synthetic substances.
Phytotherapy
has been reported to be effective in the management of ear pain in OM.
Otic solutions, such as Otikon (Healthy-On, Israel), which contains
extracts of garlic bulb, mullein flower, calendula flower and St. John's
wort herb in olive oil, or Mullein Garlic (Equinox Botanicals, Rutland,
OH, USA), which contains extract of mullein flowers, garlic, yarrow,
calendula flowers, and vitamin E, were shown to be as effective as oral
amoxicillin and topical anesthetics due to their presumed antimicrobial,
antiinflammatory, immunostimulating effects, and good penetration
through the tympanic membrane.21,22
Yet, phytotherapy has been heavily criticized by others, since the
alleged antiinflammatory properties could not be tested or confirmed in
vitro.23,24
OSTEOPATHY
Osteopathy
is a noninvasive manual medicine that focuses on total body health by
treating and strengthening the musculoskeletal framework.1
Its aim is to positively affect the body's nervous, circulatory, and
lymphatic systems, leading to “’balance” and providing overall good
health and well-being.
Osteopathic manipulative
treatments (OMTs) are occasionally used for acute and recurrent cases of
OM. The 2 most common OMTs for OM include: “Galbreath” maneuver, a
movement of the mandible aimed to indirectly generate a pumping action
on the Eustachian tube (ET);25 and “Muncie” and “modified Muncie” techniques, the placement of a fingertip on the Rosenmuller's fossa to open the ET.26
In
the largest study so far, combinations of OMTs with antibiotics
decreased the frequency of AOM episodes and the insertion of
tympanostomy tubes in otitis-prone children, when compared to
antibiotics without OMTs.27 Children who received weekly treatments had fewer episodes of AOM (P = 0.04), and fewer required tympanostomy tubes (P = 0.03).
Yet, there were no differences in the overall antibiotic use,
tympanometry measurements, behavioral parameters, and hearing results
between both groups. When considering the large drop-out rate (∼25%),
these conclusions are questionable. Other studies have shown that OMTs
administered adjunctively with standard care for children with AOM
resulted in faster resolution of middle ear effusion following AOM,
there are no serious adverse effects, and that OMTs may change the
progression of recurrent OM cases.14,28–30 The methodology of these studies is lacking; the study groups were small with high drop-out rates and lacked a control group.
Chiropratic
Chiropractic
focuses on the diagnosis and treatment of mechanical disorders of the
musculoskeletal system, especially the spine. Chiropractic medicine
believes that disorders of the musculoskeletal system affect the general
health, via the nervous system.2 The main techniques involve manipulations of the spine, joints, and soft tissues.
It
is hypothesized that spinal manipulation therapy (SMT) mediates changes
in the sympathetic and parasympathetic neural activity via the
biomechanical changes produced in the spine during treatment. Another
hypothesis suggests that cervical SMT reduces tension within hypertonic
muscles, increasing both lymphatic drainage and ET opening.31
Chiropractic is thought to prevent recurrent infections by correcting
“misalignments,” and allowing fluid drainage from the middle ear
(illustrating maneuvers are shown in Figure Figure22).
A systematic report found only a limited quality of evidence for SMT use in children with OM.31 Although there were no serious adverse effects of SMT, there was no clear evidence to support using SMT.
Xylitol
Xylitol
is a 5-carbon sugar alcohol, which is naturally found in low
concentrations in the fibers of fruits and vegetables. Fair evidence
found that xylitol reduced the incidence of AOM episodes in healthy
children.1 The alleged properties of xylitol to prevent OM are summarized in Table Table33.
In
1996, Uhari first published an RCT, in which xylitol reduced AOM
occurrence by 41%, and fewer children receiving xylitol required
antibiotics.34 Later, the same group showed that xylitol was effective in AOM prevention among daycare toddlers.35
Although ≥1 AOM episode(s) was observed in 41% of the children who
received control syrup, only 29% of the children who received xylitol
had AOM episode(s) (30% decrease, 95% confidence interval [CI]
4.6–55.4). AOM incidence decreased by 40% compared with control subjects
in the children who received xylitol chewing gum, and by 20% in the
lozenges group.
These encouraging results initiated
additional studies. In RCTs in which different xylitol remedies were
used yielded less convincing results. Xylitol was shown to be
ineffective in children with indwelling tympanostomy tubes. When xylitol
mixture, control mixture, control chewing gum, xylitol chewing gum, and
xylitol lozenges were given during an active upper respiratory tract
infection (URTI), there was no preventive effect for any of the xylitol
mixtures.36
Recent Cochrane review examined the evidence gathered for the use of
xylitol in preventing recurrent OM, and found 4 RCT studies that met the
criteria for analysis.37
Overall, it demonstrated a statistically significant reduction (25%) in
the risk of occurrence of OM among healthy children in the xylitol
group, compared with the control placebo group (relative risk [RR] 0.75;
95% CI: 0.65–0.88; 95% CI: −0.12 to −0.03). Chewing gum and lozenges
containing xylitol appeared to be more effective than syrup; however, it
emphasized that children <2 years who are at the greatest risk of
developing OM cannot safely use lozenges or chewing gum. Most studies
report a 5 times-per-day dosing schedule, which lowers the compliance in
most children. Concomitant increase of quantity in each dose reduced
the number of xylitol doses to 3-times-per-day, but resulted in various
side effects.
A recent National
Institute of Health-funded study examined if viscous xylitol solution at
a dose of 5 g 3-times-per-day could reduce the occurrence of clinically
diagnosed AOM among otitis-prone children 6 months through 5 years.32
Unfortunately, the results were discouraging, as there were no
significant differences in the occurrence of AOM and total antibiotic
use between the xylitol group versus the placebo group. Therefore, the
use of xylitol was not opted by many national guidelines as a means to
prevent OM.
Ear Candling
Ear
candling, also known as ear coning or thermal-auricular therapy,
consists of placing a hollow candle in the ear canal and lighting the
other end33 (Figure (Figure3).3). Ear coning has its roots in the traditional healing practices of China, Greece, Egypt, Tibet, and North America.
Ear
candling claims to “purify the blood” and heal children with OM through
“’cleaning” of the middle ear cleft by creating a “negative pressure.”
Little research has been performed on ear candling. Seely reported that
ear candling is implausible and demonstrably wrong, leading to deposit
of candle residue in the ear canal with no therapeutic effect on
extraction of cerumen or the middle ear.33
Furthermore, the authors stated that this therapy may be harmful,
causing ear injuries (burns, occlusions of the ear canal, and tympanic
membrane perforation), as well as otitis externa.
Vitamin D Supplement
In addition to its role in bone metabolism and calcium homeostasis, vitamin D plays a role in immunity and infection.38–43
In particular, it has been postulated that 25-hydroxyvitamin D
[25(OH)D], the isoform that reflects the individual's vitamin D status,
acts as an immunomodulator of both innate and adaptive immune systems,
by shifting the T-helper cell pool toward Th2 status, inducing
antimicrobial peptide synthesis, that is, cathelicidin and β-defensins,
and inhibiting the production of pro-inflammatory cytokines.38,40–43
Moreover, vitamin D is involved in the modulation of macrophages and
dendritic cells activities, and in regulation of toll-like receptor
mediated events in neutrophils. Therefore, vitamin D status may
influence the incidence and severity of some bacterial and viral
infections, as indicated by previous clinical studies performed in
patients with tuberculosis, respiratory tract infections, and AOM.39,44,45
Cayir et al46
published a longitudinal cross-sectional study conducted in 84 children
aged 1 to 5 years with RAOM and in 108 comparable healthy controls. He
found significantly reduced mean serum 25(OH)D levels in children with
RAOM compared to controls (11.4 ± 9.8 vs 29.2 ± 13.9 ng/mL; P < 0.05),
and an increased percentage of children with serum 25(OH)D levels
<20 ng/mL in the study group compared to controls (69% vs 30%; P < 0.05).
When vitamin D was given to children with RAOM who also had vitamin D
deficiency, the occurrence of AOM and RAOM significantly dropped during
the 1-year follow-up period. In the authors’ opinion, vitamin D
quantities may play a role in the susceptibility to OM. These data were
confirmed by the same group,47
which has recently reported in a single-blind, case–control study
significantly reduced serum 25(OH)D levels in 88 children with AOM
compared to 81 healthy controls (20.6 ± 10.2 vs 23.8 ± 10.3 ng/mL; P < 0.05).
Marchisio et al45
evaluated the relationship between decreased vitamin D levels and the
increased risk of RAOM. They studied the possible effect of vitamin D
supplementation in reducing the number of AOM episodes in 116
otitis-prone children (58 receiving vitamin D supplementation and 58
receiving placebo). They found that the number of children experiencing
at least 1 AOM episode was significantly lower in the treatment group,
when compared with the placebo group (26/58 vs 38/58; P = 0.03), and that the mean number of global AOM episodes (P = 0.03) and uncomplicated AOM episodes (P < 0.001)
occurring in the vitamin D group was significantly lower, when compared
to the control group. The likelihood of AOM occurrence was
significantly reduced in patients with serum 25(OH) D levels ≥30 ng/mL.
This study concluded that vitamin D deficiency is frequent in
otitis-prone children, and that blood 25(OH)D concentrations ≥30 ng/mL
are protective.
Despite these data,
there is not enough evidence to support a causative effect of vitamin D
deficiency on the etiology and pathogenesis of AOM, and to suggest a
protective effect of vitamin D supplementation in children with RAOM;
further controlled clinical trials are needed to solve these questions.
PROBIOTICS
Oral Probiotics
Probiotics are live microorganisms that offer health benefits by modulating the microbial community and enhancing host immunity.2
These effects can be obtained through inhibition of pathogen
colonization, production of bacteriocins, and enhancement of both
mucosal and systemic immunity.48
Commercial
probiotics preparations are based on single or multiple bacteria. Most
of the data regarding preventive efficacy of probiotics against
infections have been obtained in patients with gastrointestinal
diseases, in whom it was demonstrated that administration of probiotics
can significantly reduce the risk of development of
antibiotic-associated diarrhea.49
Data regarding the use of probiotics on OM have gathered in the last few years, showing variable efficacy.50–52 In general, the reduction in OM incidence in treated children was limited. Hatakka et al53
evaluated the possibility that probiotics could reduce the occurrence
and duration of AOM episodes or the nasopharyngeal carriage of
otopathogens in otitis-prone children. The study involved 309 children,
aged 10 months to 6 years, who were randomised to consume for 24 weeks a
probiotic daily or a placebo capsule. The probiotic treatment did not
reduce the occurrence (probiotic vs placebo 72% vs 65%) or the
recurrence (≥3 episodes) of AOM (probiotic vs placebo 18% vs 17%), while
a reduction in the occurrence of recurrent URTIs was noticed in the
probiotic group (OR for ≥4 URTIs = 0.56, OR for ≥6 URTIs = 0.59). The
administration of probiotics did not modify the nasopharyngeal carriage
of Streptococcus pneumoniae or Haemophilus influenzae, but increased the carriage of Moraxella catarrhalis
(OR = 1.79), confirming from a microbiological point of view the basis
for the negative results in prevention of AOM. These data are in
agreement with the work of Tapiovaara et al,54 who demonstrated that Lactobacillus
GG is able to penetrate the middle ear, but that its presence is not
associated with a reduction in the presence of pathogenic bacteria or
viruses.
Rautava et al55
enrolled 81 infants requiring formula feeding, who were randomized to
receive either infant formula supplemented with the probiotics Lactobacillus rhamnosus GG and Bifidobacterium lactis
Bb-12 or placebo until the age of 12 months. During the first 7 months
of life, the proportion of AOM episodes was significantly lower
(treated: 22% vs placebo: 50%, P = 0.01), and antibiotics were significantly less prescribed (treated: 31% vs placebo: 60%, P = 0.01).
However, when considering the whole 1st year of life, the prevalence of
AOM was not statistically different (treated: 13% vs 25%).
In a double-blind, placebo-controlled trial, Cohen et al56
assessed whether follow-up formula supplemented with probiotics and
prebiotics could reduce the risk of AOM. A total of 224 healthy infants
aged 7 to 13 months were randomly assigned to follow-up formula
supplemented with probiotics and prebiotics (Raftilose/Raftiline), or
follow-up formula alone. During the 12 months study period, the
treatment and the control groups did not differ in the incidence of AOM
(incidence rate ratio, 1.0, 95% CI: 0.8–1.2), lower URIs incidence (IRR
0.9, 95% CI: 0.7–1.2), or number of antibiotic treatment courses (RR
1.0, 95% CI: 0.8–1.2), which were mainly prescribed for AOM (82%). The
nasopharyngeal flora composition did not differ in the 2 groups at any
time during the follow-up.
Topical Probiotics
Topical
administration of probiotics has been considered as a method to reduce
the risk of recurrent AOM in children when administered by nasal spray.
The most largely studied microorganism has been α-hemolytic Streptococcus
(AHS), taking into account that the presence in the nasopharynx could
interfere with survival and multiplication of pathogens more frequently
associated with AOM development.57
Roos et al58
enrolled 108 otitis-prone children and, after a 10-day antibiotic
course, randomized them to receive a nasal spray containing 5 AHS
strains (selected among those colonizing the ETs opening, because of
their superior inhibitory activities against otopathogens) or a placebo
solution. Both streptococcal and placebo solutions were sprayed for a
first 10-day period and then resumed for 10 days starting from day 60 of
the study. During the 3-months follow-up, children who were given
AHS-supplemented spray experienced significantly more cure from AOM (42%
vs 22%, P = 0.02) and less recurrences (40% vs 51%, P = 0.04). The author's conclusions favored the use of AHS to protect against RAOM.
Subsequently, Tano59
randomized 43 children to receive with a nasal spray daily for 4 months
a suspension of 10% skim milk and 0.9% NaCl containing 5 selected AHS
strains with very good in vitro inhibitory activity on otopathogens, or
skim milk with 0.9% NaCl. The proportion of children with recurrences
was similar in the 2 groups (treatment group: 44%; placebo group: 40%)
and no significant changes in the nasopharyngeal colonization of
otopathogens was detected.
Skovbjerg et al60 studied the topical use of a nasal spray containing S. sanguinis, L. rhamnosus,
or placebo in children with long-lasting OME before the insertion of
tympanostomy tubes. Complete or significant clinical recovery occurred
in 7/19 patients treated with S. sanguinis compared to 1/17 patients in the placebo group (P = 0.05). In the L. rhamnosus
treatment group, no significant difference in cure rates was detected.
It should be taken into consideration that the study population was
small.
The negative results, in association with the
potential risk of infections directly due to the bacteria used for
topical treatment, have led to halting of research with these strains.
More recently, Streptococcus salivarius, an AHS isolated from
the pharynx of healthy subjects, has received attention. It is a
potential nasopharyngeal probiotic, thanks to its immunomodulatory and
antiinflammatory skills, its production of plasmin-encoded bacteriocins
and its good safety profile.57,61,62 Di Pierro et al63 evaluated the role of S. salivarius
K12 in preventing recurrent streptococcal pharyngitis and AOM in 82
children aged 3 to 12 years with a recent history of recurrent oral
streptococcal pathology, who were randomized to be administered an oral
slow-release tablet containing 5 billion colony-forming units of S. salivarius
K12 (Bactoblis) and to a control group. The 41 children who completed
the 90-days treatment had significantly fewer episodes of streptococcal
pharyngeal infections (−92.2%) and/or of reported AOM (−40%) during the
90-day probiotic intake compared to the previous 12 months (but the
difference was not significant for AOM if adjusted for the time period).
A reduction in the reported incidence of pharyngeal and middle ear
infections by 65.9% was also registered in the treatment group in the 6
months follow-up after the treatment.
Marchisio et al64 recently reported the results of the 1st study in which Streptococcus salivarius
24SMB, with significant activity against AOM pathogens, was
intranasally administered in otitis-prone children. Children aged 1 to 5
years with RAOM history were randomized 1:1 to receive an intranasal S. salivarius
24SMB or placebo twice daily for 5 days each month for 3 consecutive
months and followed up for 6 months. The number of children who did not
experience any AOM was higher among the children treated with the S. salivarius 24SMB preparation than among those in the placebo group (30.0% vs 14.9%; P = 0.076) and among children colonized by S. salivarius 24SMB after treatment compared to the noncolonized (42.8% vs 13.6%; P = 0.03). Similar results were observed when the children treated with antibiotics for AOM were analyzed (67.8% vs 95.5%; P = 0.029).
Probiotics
indeed seem a promising method in the prevention of AOM and URI but,
because of the contrasting results of the available studies, further
clinical evaluation is needed in order to assess their true potential.
CONCLUSIONS
Despite
the conservative therapeutic nature of CAM therapies for OM, which do
not include drugs or surgery, CAM is currently not considered a
treatment option for OM in the medical community, due to the limited and
confusing supporting scientific evidence. In our opinion, there may be
some benefits using homeopathy, phytotherapy, xylitol, vitamin D, and
probiotics for the prevention, and treatment of AOM. For RAOM, we have
noticed scant benefit for the use of probiotics and vitamin D. For OME, a
mild-moderate benefit was demonstrated for the use of probiotics and
xylitol. At this time, we recommend that further studies should be
conducted in order to establish the additive value of the of CAM
therapies for OM. We propose RCTs in pediatric mild-moderate AOM cases,
in which antibiotics can be deferred or withheld, so the tested CAM
therapy will be evaluated versus placebo/no treatment. We further
suggest that trials should be conducted in which infants fed with
probiotic-enriched formulas will be evaluated against others fed with
standard formula, in terms of age of 1st AOM episode and RAOM
prevalence.
