From the Editor
This issue of the RRP Newsletter
is dedicated to RRP patients, Tom McGrane, Jennifer Nicosia and Eric
Skerlak, who were members of our support group. All three died of complications
associated with pulmonary papillomas. Short memorials can be found on page
10.
During the month of January, the 17Th
Annual International Papillomavirus Conference was held in Charleston,
S.C. During the conference, I had the opportunity to meet other patients
and families of patients who suffer with this disease. For me, it was the
first opportunity to meet other patients as well as their families. It
was a very eye opening experience sharing with others the common ground
and experiences of RRP. Perhaps one of the most beneficial items was knowing
that we are not alone in the world with this disease. It is also quite
encouraging to see as many doctors and others who are involved in the fight
against RRP.
This issue of the newsletter has a
great deal of information that was presented at the 17Th
Annual International Papillomavirus Conference. As a patient, progress
can seem slow in the making, however, as you will see in this newsletter,
there are many studies going on as well as collaboration on adjunct therapies.
While a cure is the ultimate goal, there are a number of treatment options
that are offering some potential relief and encouragement in fighting this
disease.
I would like to personally thank Bill
Stern, JoEllen Bender, Caroline Dugger and Renee Randall as a great deal
of the content of this newsletter came from their summaries of the conference.

RRP Remission
News
By Patti Mandl, Marlene and Bill Stern
These very brief patient profiles are
intended to let you know that some of those with RRP are doing quite well.
Eight year old Alex from Nevada has
now been in remission for nearly 3 1/2 years. His early surgeries after
he was first diagnosed (at 18 months) were at approximately 3-4 week intervals.
Alex went into remission without the help of any adjunct treatments, only
laser surgeries, love and prayers. [ You can see a picture of Alex included
in the RRPF website gallery - http://www.rrpf.org]
Eight year old Jessica from Kansas
has been in remission since late 1996, shortly after she began treatments
with Accutane. Before that time, since her diagnosis in the mid 1993 she
had had about 20 surgeries.
Ten year old Christie from Florida
has now been in remission since June of 1998. Since diagnosis at age 2
1/2, she has had between 50 and 60 surgeries. Her surgeon believes that
her remission may be the result of painting her larynx with podophyllum
after each surgery. According to Christie's mom, you will be able to see
a picture of Christie in the June issue of Glamour magazine.
Thirty-two year old Joe from Ohio,
has not had a recurrence of respiratory papillomas since May 1997. He was
diagnosed in September of 1994 and was having surgery about every 3-4 weeks
for a period of time after that. Joe tried I3C and also PDT with no response.
In April of 1997 he traveled to Denver, Colorado to have a mumps vaccine
treatment from Dr. Nigel Pashley . He had a second treatment in May of
1997 and has been in remission ever since.
Arthur from California, age 58, has
now been in remission since early in 1998. In July 1997 Arthur was treated
with PhotoDynamic Therapy, using mTHPC. Prior to that he had over 30 surgeries
in a ten-year period.
Others still in remission include:
Seven and a half year old Ariel from California; Steph from Florida, age
26; Jeff from Illinois, age 51; William from Illinois, at age 74; Eleven
year old Anthony from Kentucky; Andrea age 32 from Louisiana; Cara from
Michigan at age 16; Emily from Michigan, now 10 1/2 years old; Leah from
New Hampshire, age 19; Lindsay from New Jersey, now 9 1/2; Julie from New
York, who is now 21; 5 1/2 year old Rita from Pennsylvania; Ralph from
Pennsylvania at age 72; Kaitlyn from Tennessee, now 6 1/2; and Smokey from
Virginia, age 27. [ Note: Several people who appeared in the Fall 98 Remission
News are not currently listed because we were not able to contact them.]
RRP Network News
Our international support network has
grown to approximately 450 respiratory papilloma families. Patients range
in age from about 2 to 84 years and are located in 44 states, the District
of Columbia, three Canadian provinces, the United Kingdom, Spain, Macedonia,
Croatia, Morocco, India, Israel, Chile, Hong Kong, Brunei and Australia.
Our thanks to all who have taken the
time to fill out the RRPF Patient/Therapy Survey. Please note the
additional questions regarding adjunct therapy side effects. Also
there is a box near the top of the front side which, when checked,
will alert us to an address change; there is a box below the name
and address section which we ask you to check if you do not want
your name and address information to be included in the RRPF Patient
Directory. We are requesting the information contained in this survey
be made available for RRP research. In this regard there is a place in
the survey to grant permission.
As our support network has grown, we
have become more dependent on the patient questionnaires to maintain our
mailing list and keep our database of RRP patient information up to date.
So if you haven't completed a questionnaire in the past, please take
a few minutes to fill out the form enclosed. If you have previously
filled out a questionnaire, you need only identify yourself, mark UPDATE
along the top front of the form and answer only those questions where you
have new or updated information to provide. Please return the surveys to
Marlene and Bill Stern. (See "RRP Web News" article below for information
on completing and submitting surveys via the World Wide Web) In addition,
RRP families, please review the Patient Directory listings and notify
us regarding any corrections, omissions or additions. If you are not
included in the directory and would like to be (or vice versa), please
notify Bill or Marlene Stern.

RRP Patient
Stats
[In this issue we
will be publishing a special article on estimation of the number of lifetime
surgeries for RRP patients, based on statistics from the RRPF database.
A general updating of RRP patient statistics will be deferred until the
Fall 99 issue]
Estimating
the Number of Lifetime Surgeries for RRP Patients
by Bill Stern
RRP is characterized by significant
morbidity with the need for repeated surgeries. An ability to make an estimate
of "lifetime" surgeries that an RRP patient might anticipate, would be
a useful part of the disease prognosis process. Unfortunately, this is
extremely difficult to do for any individual patient, as there is great
variability in the frequency of these surgical procedures especially among
juvenile onset RRP (JORRP) patients (see fig. 1, p. 5, Fall 98 RRP Newsletter,
hereafter referred to as F98f1).
The data used in this study comes from
the RRP Foundation patient database (Shah et al., 1998). In particular,
197 RRP patients or parents have provided information regarding total surgical
procedures, diagnosis age and birthdate as part of the RRPF patient questionnaire
forms. From F98f1 there is a suggestion that those most likely to experience
a large number of lifetime surgeries would be JORRP patients who are diagnosed
in the first few years of life, while those diagnosed as adults (AORRP)
might anticipate significantly fewer surgeries. However, because F98f1
includes patients who have had RRP from less than 1 to over 60 years, it
is virtually impossible to obtain a statistical estimate of lifetime surgeries
from this diagram alone.
The procedure used for estimating lifetime
surgeries in this report is as follows: 1) Separate estimates will be made
for AORRP and those with JORRP. 2) The JORRP and AORRP groups are each
binned into 5 sub-groups based on years with RRP, i.e., >0, >5, >10, >15,
>20. 3) The mean and 95% confidence intervals are computed for total surgeries
in each sub-group, assuming that they are part of a population that is
normally distributed. These data are plotted in figures 1a and 1b for JORRP
and AORRP respectively, with sample sizes for each sub-grouping indicated
in brackets. In figure 1a it is seen that for those with more than 10 years
of JORRP, the mean number of expected lifetime surgeries appears to be
asymptoting to about 80, with a 95% confidence range of 60 to 100. For
AORRP (figure 1b) a nice convergence in the mean number of surgeries is
not as evident as time with RRP increases, but it still suggests a mean
number of expected lifetime surgeries of 20-25 within a range of about
13 to 35.
Caution is urged in using this statistical
information to attempt to predict the number of expected surgeries for
an individual RRP patient, as each case is somewhat unique. However, this
information could be beneficial for providing a priori public health cost
estimates associated with RRP including cost benefit analyses of this disease.

Highlights of
the HPV International Conference
Edited by Bill Stern et. al.
Perspectives of RRP Families in
Attendance
The 17Th
International HPV Conference was held in Charleston, SC from 9-15 January,
1999. There were 18 patients/family members who attended. All of the attendees
indicated that they appreciated the opportunity to meet other RRP patients
and families, face to face, and hear about the issues and emotions that
they have faced in dealing with this disease. It was clearly a positive
experience to be among other people who could understand what RRP can do
to your life. Most RRP family members welcomed the opportunity to meet
with RRP doctors outside of the office environment. Another major highlight,
from the RRP perspective, was the 1 1/2 hour scientific session devoted
to RRP. We believe it was the first time RRP was exclusively scheduled
as part of the HPV conference.
RRP
Foundation Support Meeting
International Papillomavirus Conference-1999
Sunday morning the RRPF held a meeting
that was attended by about 13 doctors and/or researchers in addition to
all 18 RRP patients/parents. Each of the patients or a parent of a patient
introduced themselves and told a brief history of their respective disease
experience. Caroline Dugger, who was the only one in attendance with a
tracheostomy, brought along draft copies of her book, " A tracheostomeeÇs
guide to care and well being".
Dr. David Bishai, a health economist
from Johns Hopkins who is quite interested in the economic impact of RRP,
asked about the costs of living with the disease as well as the pain and
other issues of coping. Some of the patients expressed some of the cost
issues in terms of lost time at work, forced retirement for one person
as well as some stories of those with jobs that are very flexible in terms
of taking time off to handle treatment of RRP. With regard to pain, most
patients and parents indicated that it was not a significant factor.
Other discussion issues included the
fears of dealing with RRP. Some parents of RRP children mentioned that
fear of surgery was a major problem. Some of the patients expressed that
it is harder to recover from surgery as an adult, while others were intimidated
by the IV. Other issues included a discussion as to when should a patient
be operated on and who should be the judge. Some folks believe in delaying
surgery as long as possible, while others feel it is appropriate to have
surgery sooner than later since it shortens the recovery time. The fear
of a fire related to the laser igniting the endotracheal tube was raised
by one adult patient. According to Dr. Mark Shikowitz, of L.I.J., todayÇs
technology makes this virtually impossible. He also stated that if a patientÇs
anesthesiologist is not using some of the newer techniques, he will be
happy to have his anesthesiologist discuss this with them.
There was a brief discussion with regard
to the ability to "cough off papilloma", especially in the case of some
patients with tracheostomies. Most doctors seemed skeptical.
There was a discussion regarding the
value of specifically typing the papilloma. By knowing the specific HPV
types, it was suggested that it might be possible to identify those patients
who might be more likely to have aggressive disease.
One doctor suggested that with the
current turmoil of the insurance system and HMOÇs refusing care
to some patients, that it might be better to leave the typing unknown.
Thereby, providing fewer reasons to exclude a patient from insurance coverage.
On the other hand it was suggested by at least one researcher, that knowledge
of the specific types could lead to more effective treatment options.
Some patients expressed some frustration
with the time and process of getting certain therapies approved. Dr. Jerome
Thompson, from the University of Tennessee, explained the reasoning behind
the stringent requirements and what the medical community is looking for.
The point of his discussion was to point out that it is only through stringent
standards of trials do we get improved medical procedures vs. therapies
that are not successful. While this may be frustrating to us a patients,
it is ultimately in the best interest of all.
Scientific
Session on RRP
International Papillomavirus Conference-1999
Following the RRP support group meeting,
the conference held a scientific session dedicated exclusively to RRP.
This session on RRP began with an introductory clinical description of
the disease by Dr. Haskins Kashima, from Johns Hopkins. The presentations
were divided into two groups. The first part focused mainly on epidemiological
aspects of the disease and was chaired by Dr. Bettie Steinberg, from L.I.J.
Dr. Kashima chaired the second group of presentations which dealt mostly
with RRP therapies and treatments. Summaries of the therapy discussions
can be found under the heading Adjunct Therapies, later in the newsletter.
Bill Stern of the RRP Foundation, opened
the presentations with a talk about the major impacts of RRP on the lives
of patients and their families. The disease can be life threatening and
is often characterized by great morbidity. Nearly everyone with RRP experiences
a degree of voice disorder. Some so severe that they have virtually no
voice, others are only slightly affected. Perhaps the most relentless aspect
of this disease is the need for repeated surgeries. A chart of the total
number of surgeries for 17 juvenile onset patients with RRP (JORRP) for
more than ten years (mean disease duration was 32 years, with a range from
14.5 - 62 years) indicated a mean of 89 surgeries with 95% confidence interval
of + or - 33. Perhaps the most life threatening aspect of RRP was the spread
of the disease to the lungs, which occurred in about 5% of the cases according
the RRPF data.
Dr. Lori Armstrong from the Centers
for Disease Control, followed with a presentation of the initial results
from their JORRP registry. Data has been collected from 21 medical centers
(at the time of the conference) nationally for active cases of RRP in children
up to the age of 17.
Dr. David Bishai from Johns Hopkins,
presented preliminary results of a cost benefit analysis of preventing
JORRP. The purpose being to quantify the cost of doing, or not doing a
cesarean section (CS). The study looks at the medical costs of CS and medical
costs associated with JORRP and makes an assumption of a mean of about
20 lifetime surgeries for JORRP patients. In summary, based on a variety
of assumptions (including cost of pain and suffering to patients and parents
), even with an efficacy as low as 50 CS to prevent one case of JORRP,
the value of the social benefit of JORRP prevention would outweigh the
cost associated with necessary CS.
Dr. Keerti Shah from Johns Hopkins,
discussed the risk factors for JORRP and the rationale for a multi-center
study. Key points he outlined are as follows:
JORRP is preventable, since we are
confident that in most cases transmission of HPV-6 or HPV-11 occurs in
the infected maternal genital tract. In this regard it is quite similar
in transmission of herpes. He speculates that the chances of developing
RRP in a child born to "high risk" mothers presenting is about 1 in 35.
A general population risk is estimated at about 1 in 3,500. At present
there are no guidelines on how JORRP might be prevented. In order to help
establish some guidelines, a randomized trial is proposed to follow condylomatous
mothers for five years (since 75% of all cases present within five years).
If a formal trial is not possible, "we can at least observe". It does appear
that CS would prevent 90% of all cases.
[The remaining issues during this
conference session dealt with adjunct therapies and can be found under
the heading Adjunct Therapies, later in the newsletter.]
..........................................................................................................
Adjunct
Therapy and Protocol Update
The following reports of statistics
and clinical research involving RRP therapies, represents a best effort
by the RRPF to make an accurate and objective presentation of information
obtained from a variety of sources. The RRPF does not endorse any particular
product but will make suggestions when deemed appropriate.
[Support network adjunct therapy
statistics will next be updated in the Fall 99 RRP Newsletter issue - see
the Fall 98 issue for previous statistics.]
Interferon
Efficacy and Brands of Interferon*
by Bill Stern
It has been suggested that there might
be a substantial difference in the effectiveness of two types of interferon
due to the formation of neutralizing antibodies. Specifically, evidence
that a much higher percentage of patients (Leukemia and Hepatitis C) being
treated with Roferon-A developed neutralizing antibodies than those
being treated with Intron-A. (It should be noted that Roche has
produced a reformulated Roferon after 1996. It is not yet known whether
this new Roferon has less of a tendency to develop neutralizing antibodies).
Thus far we cannot see this impact in data reported to the RRPF. Of 43
patients indicating on their RRPF surveys that they are using or have used
interferon regularly, 17 treatments with brands have been reported (see
table 1). Furthermore, in a careful reading of the Leventhal et al., 1991
article, detailing the Johns Hopkins 66 patient interferon study for RRP
patients, it is evident that they were concerned about the possibility
that neutralizing antibodies might result in a loss of effectiveness, however,
in this study the presence of neutralizing anti-bodies did not appear to
have a significant impact.

We asked an expert on interferon and
HPV, Dr. William Bonnez from the University of Rochester, for his comments
on neutralizing antibodies and interferon, the following is an excerpt
of some of his comments:
"...These neutralizing antibodies appear
to have an adverse effect on in vivo interferon activity. Several reports
have indicated that the presence of interferon neutralizing antibodies
was associated with treatment failure (e.g., multiple sclerosis and interferon
beta, hepatitis C and interferon alpha,...) and that the administration
of a different interferon, typically a natural interferon alpha, could
overcome treatment resistance (this has been shown in the case of hepatitis
C). Natural interferon alpha is constituted by several species of interferon
molecules. Antibodies directed to one species, e.g. alpha-2, do not seem
to cross-react with another species, e.g. alpha-1. This is why presumably
natural alpha interferon retain
most of its efficacy..."
"... I have been involved in the only
three studies that have looked comparatively at the efficacy of different
interferons, either intralesionally or systemically administered, for the
treatment of genital warts ...We did not observe any differences in efficacy,
or lack thereof, among interferon preparations..."
"... However, if in a given patient
one observes there is lack of clinical efficacy, I think it would then
be appropriate to try a different interferon preparation, preferably moving
from a recombinant interferon to a natural interferon..."
Based on Dr. Bonnez's comments, it
is somewhat surprising that most RRP patients being treated with interferon
are not using a natural product. In this regard, Alferon
(a human leukocyte derived alfa-n3 interferon produced by Interferon Sciences)
, is readily available. In addition, it is approved for treating genital
HPV and is very similar to the interferon used in the Cuban national study
involving 125 RRP patients (Deunas et al., 1997), which showed significant
efficacy.
Although there has been some differing
opinions between the RRPF and the RRP Website (and in scientific literature)
regarding the extent to which neutralizing antibodies may impact the efficacy
of some interferon products, both organizations currently see Alferon
as a potentially promising interferon product for the treatment of RRP.

Update
on Cidofovir
A
Phase I/II Evaluation of Cidofovir Therapy for Recurrent Laryngeal Papillomatosis
in Children
In 1997 a research group from Belgium
reported (Wellens et at., Proceedings of the XVI World Congress of Otorhinolaryngology
Head and Neck Surgery, Sydney, Australia) on the treatment of 17 RRP patients
(mostly adults) using cidofovir (also known as HPMPC). The procedure involved
intralesional injections during laser surgery. After follow up periods
ranging from 2 to 27 months, it was reported that 13 of the 17 patients
were in remission.
Based on these early encouraging results
a clinical trial is being proposed in the U.S. It will be a Phase I/II
mulit-centered trial sponsored by the NIH/NIAID Collaborative Anti-viral
Study Group (CASG). The purpose of this study is to define the safety of
cidofovir infiltration of laryngeal lesions following debulking. Enrollment
in this dose escalating, double blind study will be offered to pediatric
RRP patients with aggressive disease, meeting strict eligibility requirements.
If you are interested in obtaining
additional details of this proposed study, it is suggested that attending
physicians contact:
David Kimberlin, MD or
Jan Kiell, RN

Fax: 205-934-8559
[Clark Rosen, MD has been using Cidofovir
intralesionally on a handful of RRP patients for about a year with some
good preliminary results. See Spring 98 RRP Newsletter for more
background information on Cidofovir provided by Dr. Rosen.]

I3C / DIM
- Update
For background information about the
impact of indole-3-carbinol (I3C) on estrogen metabolism and how this subsequently
may act to reduce the growth rate of respiratory papillomas, see the RRP
Newsletters Fall 93 through Fall 94 and Fall 97 for DIM, as
well as Bradlow et al., 1996 J. of Endocrinology 150, S259-S265;
Newfield et al., 1993, Anticancer Research 13, 337-342. Much
of this information is also available from the RRPF website at: http://www.rrpf.org/rrpf/therapies/I3C_DIM.htm.
I3C Stability
by Bill Stern and Michael Green
[ The following article on I3C stability
contains excerpts from a joint cautionary statement by the RRP Website
and the RRPF
(see -http://www.rrpf.org/rrpf/RRPF_bulletin.htm#I3C_announce
for more details) ]
I3C is reportedly very unstable when
exposed to heat and light, and concern has been expressed in scientific
literature about some of its condensation products when it breaks down.
We have recently learned that Theranaturals is currently shipping I3C that
was made about a year ago and reportedly has no plans to make up any new
batch for at least another 6 months. Theranaturals states that it has reviewed
the scientific literature and believes that I3C is stable for up to two
years when stored in an air filled bottle and when stored away from light
in an air conditioned environment. [Note that Sigma, which distributes
a highly purified I3C (mostly for experimental animal studies), considers
the product so unstable that it stores it under argon gas at 2-8 degree
C (refrigeration).]
We have had samples from a recently
acquired
bottle of Theranaturals I3C analyzed by mass spectroscopy. Analysis results
do indicate that the product is still mostly I3C (excluding insoluble filler).
Given I3C's known instability this result was somewhat surprising to us.
We still have unanswered questions relative to the test results and the
testing process (see below) If you are currently taking the Theranaturals
product with positive results, we suggest that you continue using the product.
We are also suggesting the possibility of a combined therapy approach.
(A number of patients in the RRP community are successfully following a
regimen of using both I3C and DIM/Indoleplex on alternate days.)
Although our two tests suggest that
the Theranaturals I3C product does not appear to be degraded, it is not
clear whether the analyses by mass spectroscopy are capable of identifying
and resolving all trace condensation by-products, some of which might be
problematic. We will continue to investigate these issues. Further discussion
is needed with those responsible for the two tests conducted thus far,
and we may be submitting other samples of the Theranaturals product for
more testing. We strongly encourage Theranaturals to produce I3C on a much
more frequent basis to better assure the full potency and purity of their
product.
University of Pittsburgh I3C Study
By Clark A. Rosen MD
This study is now over four years old
and clinically, we have seen very good responses to I3C and no toxicity.
We are presently finalizing all data in order to submit the results to
a medical journal. At present, we are missing 40% of the patient group
due to "lost to follow up". This is skewing the data because most likely
only responder patients have kept in contact. We are looking for all people
even remotely involved in the study.

in any way, please contact the following individual:

RRPF I3C Research Coordination Efforts
The RRPF continues to encourage research
studies involving I3C as an RRP adjunct therapy. In this regard we suggest
that those patients who are interested in I3C as an adjunct treatment for
RRP become part of a clinical trial. For those who are unable to participate
in an I3C trial, but who would like to pursue this therapy on their own,
we have been providing information regarding how and where to get I3C
and how much to take. In addition, we continue to supply urine analysis
testing information and supplies to RRP patients upon request. Thus far
we have had requests for and have mailed out approximately 100 test kits.
Along with the kits detailed instructions are included for collecting urine
samples and sending them to Strang Cancer Prevention Center for analysis.
In this regard we ask for your patience. These analyses are being performed
as part of a research program by a limited number of scientists who depend
on various funding sources to cover laboratory expenses. The RRPF will
continue to assist their efforts.
How to get I3C and how much to take
Indolplex TM
products containing DIM are available from:
BioResponse
L.L.C. at P.O. Box 288
Boulder, CO 80306 (303) 447-3841
Email at zeligsmd@sni.net
Indolplex is available in two forms:
1. Indolplex Capsules -
150 mg - 60 capsules per bottle - cost is $33/bottle or 75
mg - 90 capsules per bottle.
2. Indolplex Flavored Sprinkles
- 9.0 grams per bottle with directions indicating dosage per teaspoon.
At the suggested dosing below, 1 bottle should provide a two-to-four month
supply for a child about 50 lbs.
Estimated dosages - BioResponse
has recommended that individuals with RRP choose a daily dose which is
close to 4 mg/kg/day. To be close to 4 mg/kg/day a typical man weighing70-85
kg (where 1kg. = 2.2 lbs.) would take from 300 to 375 mg per day. A typical
woman weighing 60-70 kg would take from 225 to 300 mg per day. The dose
of "Sprinkles" can be individualized with each quarter teaspoon being appropriate
for each 16 kg of body weight (approximately 35 pounds).
(Please consult your doctor, especially
for young children. See the RRP
Newsletter Fall 98 issue for more information on Indolplex )

Theranaturals is selling I3C in
capsule form, each capsule will be guaranteed to contain 100 milligrams
of I3C. Each bottle will contain 100 capsules.
Pricing (which includes shipping via
USPS priority mail) : $40.00 for one bottle; $110.00 for a package of
3 bottles
add $16.00 to above prices for Fed

Important: For this pricing you
must let Theranaturals know that you are an RRP patient/family and they
will assign you a special customer number.
Approximate dosing
information is based on preliminary results of Dr. Leon Bradlow's estrogen
metabolism studies, as follows:
Estimated dosages - Adults
approx. 400 mg, Children (under 50 lbs.) 100 - 200 mg (Please consult your
doctor)
Additional I3C Notes
The digestive process is important
to
properly break down I3C (see RRP Newsletter - Spring 94 ). In this
regard, try to avoid taking antacids and it is probably best to take I3C
at meal time. It has also been suggested that taking ascorbic acid (vitamin
C) along with I3C will produce ascorbigen, which some investigators (Preobrazhenskaya,
et al., 1993, Food Chemistry, 48,48-52) speculate may be
an even more important anti-carcinogen than I3C.
If you do not appear to be responding
to I3C, you might want to give DIM (Indolplex) a try.
Finally, no matter what product one
is using the best way to extend the shelf life is to keep them in a cool
dark location such as the refrigerator.
I3C/DIM reported side effects:
ï Occasional gastro-intestinal
upset.
ï A couple of instances of dizziness
ï Some speculation that I3C/DIM
might affect bone density (see RRP
Newsletter - Fall 98)

Adjunct
Therapy Presentations and Discussions from the International Papillomavirus
Conference-1999
Cidofovir General Discussion
A discussion during the RRP Foundation
Support Net meeting, led by David Kimberlin, MD, David Malis, MD and Dr.
Tom Broker centered on recent developments utilizing cidofovir as well
as a general discussion of how cidofovir works. In particular, cidofovir
is absorbed by the host cell, which converts into an agent that kills cells
which have HPV in it. It is essentially not absorbed by non HPV cells.
This is called a pro-drug, which converts into an active drug. The selectivity
is quite remarkable, such that, there is three orders of magnitude more
absorption in papilloma cells vs. non disease cells. Thus it is speculated
that this conversion to an active form will take place only in cells that
have active HPV. It is also worth noting, that Dr. Broker feels that this
is a very promising drug and the trials will tell us much more.
Ribavirin
By Ronald Ostrow, MD
University of Minnesota
Results from a double blind, crossover
clinical trial using Ribavirin for the treatment of RRP were presented.
Positive preliminary results involving Ribavirin as an adjunct for RRP
had been established in animal studies and in a small uncontrolled pilot
study involving human patients. This was a very well designed study, which
was tightly controlled. Despite low enrollment (approx. 10-11 patients),
it was possible to show that an increase in the interval between surgeries
for those in the group using Ribavirin was statistically significant. Furthermore,
while Ribavirin may have an impact in less than six months for some patients,
its effect may be delayed or continue beyond its administration period
for others.
PhotoDynamic Therapy using Foscan
(mTHPC)
By Mark Shikowitz MD
L.I.J.
There are currently 16 patients enrolled
in this protocol, 7 juvenile and 9 adults. At this time 8 patients have
been studied long enough (defined as at least 12 months after treatment)
to draw some preliminary conclusions. Five are said to be free from disease
and two others have shown marked improvement. Improvement was not immediate,
but rather, there appears to be a lag response. All patients continue to
show disease at 3 months after treatment, with significant improvement
occurring at 6 or 9 months post PDT. The new PDT keeps the patient light
sensitive for 2-3 weeks vs. the older drug which was often 2-3 months.
Indole-3-Carbinol (I3C) and RRP
By Karen Auborn Ph.D.
This presentation outlined how estrogen
plays at least a partial role in the susceptibility of the larynx to HPV.
Animal models clearly support this. There are two competing estrogen metabolites,
i.e. C-2 and C-16a.
It was found that 16a hydroxylation
was significantly increased in laryngeal papillomas. Dr. Auborn discussed
how I3C agents bind the AH receptor which includes 2 hydroxylation. Several
clinical studies have since demonstrated this. First in mice and more recently
in a human RRP patient trial. Unfortunately, in some patients I3C does
not induce 2 hydroxylation. Although it appears quite safe, long term studies
of the anti-estrogen I3C, at pharmacological doses are needed. In summary,
I3C and newer derivatives continue to show promise in treating papillomavirus
induced diseases.

Predicting
the Behavior of RRP: The University of Tennessee Clinical Study
Todd Snowden, MD and Jerome Thompson
MD
Despite our understanding of HPV types
responsible for the great majority of juvenile-onset RRP, the behavior
of this disease in children remains frustratingly unpredictable. As those
familiar with this disease can attest, some children with RRP have a relatively
benign course, while others have extremely aggressive disease with distal
spread and frequent recurrences. At the extreme of this clinical spectrum
can lie malignant transformation or even death from uncontrollable disease.
In order to target pediatric patients
with RRP at high risk for aggressive disease, investigators have tried
to identify individual factors to reliably predict severity of disease.
The possible prognostic significance of several markers in papilloma tissue
has been reported: as of yet, however, no easily obtainable blood tests
have been identified to predict the course of RRP in an individual child.
Cytokines, circulating proteins produced
by white blood
cells, have long been know to play
critical roles in the bodyÇs disease response. Of special interest
in the context of RRP, is the effect of cytokines on tumor growth. Interleukin-2(IL-2)
is a key player in the cytokine response and stimulates the proliferation
and activation of the bodyÇs T-cells. T-cells may be directed against
virus-infected or neoplastic tissue. In this regard, IL-2, may have significant
anti papilloma activity.
The predictive role of IL-2 and its
soluble receptor, SIL-2R has been investigated in patients with genital
HPV-related tumors. An inverse correlation has been reported between IL-2
levels and recurrence rate of genital HPV, and a direct correlation between
IL-2R levels and recurrence rate. To date, there have been no studies investigating
the predictive value of IL-2 or IL-2R in HPV infection of the upper respiratory
tract.
The objective of our study is to determine
whether levels of serum IL-2 and IL-2R in patients with RRP have value
in predicting the frequency of surgical intervention. Currently, a pilot
study is underway at the University of Tennessee comparing our population
to a group of age-matched controls.
RRP is an uncommon disease, and the
majority of patients who have it are spread throughout the country. Therefore,
we are in the process of requesting serum samples from patients with RRP
at other centers to assay for interleukin-2 and soluble IL-2 receptor.
In this way, we can accumulate a subject population large enough to establish
statistical significance. Interested health care providers, families, or
patients are encouraged to contact:

Coordination
of Research in Pulmonary Papillomas
By Bill Stern
The untimely deaths of three members
of our support network in approximately the past three months has brought
a shocking reminder of how RRP can indeed be life threatening. Pulmonary
papillomatosis represents one of the great treatment frustrations to the
RRP medical community. Although there are a few clinical researchers who
have shown an interest in trying to develop treatment protocols for pulmonary
papillomas, I am not aware of any coordinated efforts. In this regard,
the RRPF is proposing to coordinate information from existing studies involving
pulmonary papillomas and encourage ideas for future studies. To date a
pulmonary papilloma study group consisting of about a dozen members of
the RRP doctor/researcher/patient community has been established.
If you have an interest in pulmonary
papillomas and have not been included in the pulmonary papilloma e-mail
list, please contact Bill Stern at bills@rrpf.org.

Patient Profile
The Voice of Love
By Peggy McCracken and Paul Villano
Writing about my story, I feel like
I am writing one of those police dramas I watched as a child. You know
the story. Only the details are different. But I am hoping that by sharing
the details of my personal story it will make the details of your own story
less painful and let you know that you are not alone. We know, we share
the same hurts and hopes, and we care.
I was born in Charleston, West Virginia
46 years ago. (I donÇ t mind whispering when it comes to my age!
Looking younger is every womanÇs dream.) Everything was fine for
the first 18 months of my life. But by then it was obvious that I was losing
my voice and having trouble breathing.
My parents began the pilgrimage of
taking me from one doctor to another until we finally found an eye, ear,
nose, and throat specialist who knew what the problem was. The doctor did
not call this RRP. He just said that I had warts on my vocal cords.
That wasnÇt all the excitement
I was due for, however! The problem got compounded when I was about 2.
The car I was riding in was involved in a car accident and I was left with
50% paralysis on my left side. To this day, I have only partial use of
my leg, arm and hand, and eye control on this side.
Over the years, there have been many
surgeries for RRP. It has continued to block my airway and put extra strain
on the use of my vocal cords. Regular visits to the doctor will always
be a part of my life until a cure for this disease is found.
The hardest part of my various disabilities
over the years have been the loss of my voice. It might have been comical
if it hadnÇt been such a nuisance, when Social Services repeatedly
called my parents in to tell them that I needed to see a doctor for my
sore throat, or laryngitisÖ I was forced to take speech therapy classes
that I didnÇt need because the school system just didnÇt
know how else to handle someone with this condition.
When puberty came, some changes that
the boys seemed to appreciate came too! Doctors said that puberty would
stop the RRP, but that didnÇt happen at that time or later.
Years later, there were short periods
of remission from time to time but it was never a permanent remission.
Between the age of 30 and 38 I had eight years of relief and life was wonderful.
In January of 1988 my husband had a
job transfer, so our family moved to Columbia, South Carolina. I had to
have emergency surgery because the RRP growths seemed to start growing
at a very rapid pace. Another surgery followed close behind and then another
after a couple of months. Surgery throughout the 1990Çs has averaged
about once every year or two, with the most recent operation in August
1998.
So that is where I am today. I work
as a sales associate in a retail store and must admit it can still be a
hassle from time to time as customer after customer asks, "WhatÇs
wrong with your voice?" "Do you have laryngitis?" "It hurts my voice to
listen to YOURS"! I feel like wearing a button that says, "Yes I always
talk this way"! Instead, I just use some humor, I may wink and say,ÖÖ..
"This is my SEXY voice" and let it go with a smile.
IÇve learned that, in no matter
what condition you find yourself, whether it is RRP, or paralysis, for
that matter, or whatever it may be, you can still have a full and rich
life. It can only take control of your life and your emotions if you let
it.
So when the 10,000th person asks you,
"WhatÇs wrong with your voice?" feel free to use my "sexy voice"
line, or some other funny line. It helps.
I know who I am and what I have. I
have been married to the same wonderful man for 25 years of ups and downs
which are just part of the realities of life. We have three beautiful children
(2 sons, 1 daughter), I am also a student in the paralegal program at the
local college, and I have RRP. It is just one color in the rainbow that
is my life. You may be dealing with RRP, but that is only one small part
of the person you are.
As a Christian, I know the LORD gave
us the rainbow as a sign of encouragement. I hope that my life will encourage
those around you, to face life with courage and joy, whatever the circumstances.
Your voice may only be a whisper, but you can still speak in a voice of
love that comes out loud and clear from the heart.

In Memory
Jennifer Nicosia battled RRP
since her diagnosis at 11 months of age. In all she underwent over 150
surgeries. The first evidence of pulmonary papillomas were first noted
when Jennifer was nine, but it was in recent years that the papilloma in
the lungs progressed significantly. Despite all this she never complained
- her courage touched many of us. She passed away in December 1998 at the
young age of 25.
Jennifer is survived by her parents
and a younger sister.
Tom McGrane struggled with pulmonary
papillomas for a number of years and had well over a hundred surgeries
since he was diagnosed with RRP at the age of 12. Those who knew Tom well
said he was kind, uncomplaining and never wanted any special treatment
because of his disease. Despite his aggressive disease, Tom was able to
pursue a successful career as an attorney for the Attorney General's office
in the state of Iowa for 27 years. He passed away in early January 1999
at the age of 58.
Tom is survived by his wife, two daughters,
one son and a grandchild.
Eric Skerlak endured more than
120 surgeries for RRP, since his diagnosis at the age of 15 months. He
had papillomas in his lungs for at least the last 6 1/2 years. Despite
his extremely poor lung function, he tried as much as possible to be a
normal active boy. At the end of March 1999 he passed away cutting his
life terribly short at the age of 17.
Eric is survived by his parents and
three older sisters.
We will miss all three of these courageous
members of the RRP community very much. |
