prescription drugs for gastrointestinal and respiratory diseases.
INTRODUCTION
A new method has been
developed for diagnosing gastro-oesophageal reflux disease and assessing
treatment progress. Until now, assessing the progress of treatment for
Gastro-Oesaphageal Reflux Disease (GORD) has relied primarily on an assessment
of oesophageal healing. Documenting GORD therapy success is a difficult task,
as mucosal damage does not always correspond with the severity of symptoms.1 In
addition, 70% of all patients with
GORD symptoms have
endoscopic-negative GORD. To further complicate the GORD picture,
Endoscopy-Negative Reflux Disease (ENRD), Non-Erosive Reflux Disease (NERD),
functional heartburn or reflux-like dyspepsia is often diagnosed, and most
patients with
heartburn do not have
mucosal breaks. Moreover, diagnostic approaches vary between primary and
secondary care. In the absence of gold standard diagnostic testing for GORD,
symptom assessment and understanding how symptoms impact on a patient’s quality
of life is critical to the successful management of a patient. Recent research
has suggested that the symptom complex experienced by GORD patients is much
wider than previously appreciated. Besides heartburn, acid eructation, and pain
on swallowing, a variety of other GORD-related symptoms are experienced,
including nausea, diarrhoea or constipation and sleep disturbance, as well as
other symptoms, such as respiratory complaints. GORD is a condition of diverse
and variable symptoms, many of which significantly impair quality of life. The
problem for gastroenterologists trying to build a complete picture of a
patient’s symptoms is that patients may find it difficult to describe
accurately all the symptoms they are experiencing. Consequently, they may not
be treated effectively. Even after successful acute treatment, the majority of
patients suffer a recurrence of symptoms within six months. And, if the
non-classic signs of GORD are not seen, patients may be misdiagnosed. The broad
spectrum of symptoms in GORD patients and the high prevalence of
endoscopy-negative GORD highlight the need for a robust, validated approach to
symptom assessment.
SIMPLE
QUESTIONNAIRE
One such approach is
ReQuest™, a simple and effective questionnaire, which patients use to assess
themselves
daily for a wide
range of GORD symptoms. It was created following discussions with patients and
physicians to identify the spectrum of symptoms reported and establish how they
were described by GORD patients. The questionnaire was also based on an
evaluation of relevant medical literature and clinical trial data. ReQuest is
divided into seven dimensions covering acid complaints, upper abdominal/stomach
complaints, lower abdominal / digestive complaints, nausea, sleep disturbances,
general well-being and other complaints. A short version of the questionnaire,
which can be completed in less than five minutes, focuses solely on these seven
dimensions, while the full version, which takes approximately 20 minutes, is
more wide-ranging. Both tests have undergone extensive clinical trial
evaluation and statistical analysis, which has confirmed their internal
consistency, test-retest reliability, construct validity, and responsiveness to
changes during treatment. ReQuest fulfils the criteria set by the regulatory
authorities for a validated symptom-based system for use as the primary outcome
measure in clinical trials of GORD therapy. It has now been validated in 26
languages and tested
in 20 countries.
REQUEST
/ LA CLASSIFICATION
The ReQuest / LA
classification system is the first to effectively integrate a highly sensitive
patient questionnaire (ReQuest) with an adaptation of the LA classification for
esophagitis. The new index allows the combined assessment of symptom relief and
the healing of oesophageal lesions in GORD. The adapted LA classification (N =
lesions not present, grade A–D) was paired with a grading of patients’ symptom
burdens from 0–4 (0 = no disease, 1 = minor, 2 = tolerable, 3 = troublesome, 4
= intense), as assessed by the rescaled subscale of the established GORD
symptom evaluation instrument ReQuest. By comparing both scales in a matrix,
clinicians are able to quantify both aspects of GORD and assign an index to
each patient. An index of 0N indicates optimal treatment outcome, in other
words complete remission (relief from symptoms and the healing of oesophageal
lesions).
VALUABLE
INSIGHTS
A randomised,
double-blind study of 581 patients using ReQuest has established that
pantoprazole is as effective as esomeprazole (both 40mg/day) over 12 weeks in
achieving the complete remission of erosive GORD. With respect to
endoscopically confirmed healing, pantoprazole was superior to esomeprazole. A
second randomised, double-blind ReQuest study, this time of four weeks’
duration (561 patients), again comparing pantoprazole and esomeprazole (both
40mg/day), demonstrated parity between the two PPIs in terms of symptom relief
scores, but it also showed that the beneficial effects of pantoprazole were
sustained for longer, with significantly fewer symptomatic relapses in the
seven-day post-treatment phase. Professor K D Bardhan, consultant physician and
gastroenterologist at the District General Hospital, Rotherham, in the UK, who
was instrumental in developing the ReQuest/ L A classification, says: ‘We need
a device that enables an accurate assessment of treatment success in GORD
patients that combines the main parameters of symptom relief and oesophageal
healing. The new ReQuest / LA classification enables a detailed clinical and
treatment outcome assessment of GORD patients at any stage of their disease
using a single and reliable global measure. In my view, ReQuest / LA
classification represents a helpful step in the right direction and provides a
means of standardising the assessment and reporting of GORD clinical trials.’
An extensive ReQuest database, which provides information on patient
demographics, symptom profiles and treatment outcomes, now exists for over
8,000 patients with GORD. Use of the combined endpoint ‘complete remission’,
evaluated using the ReQuest™/LA classification, will permit even greater
insights by helping to analyse patient populations and shed light on the
factors that dictate whether a treatment works. Such a source of GORD treatment
outcomes, during various stages of the disease, could be of major benefit to
patients, physicians and the organisations that fund healthcare in the future.

Case -2 --A New Concept in Annuloplasty for Valve Repair: the
Biodegradable Ring –
BIORING
COMPANY PROFILE
BIORING, founded in
2000, develops and commercializes biodegradable medical devices that lower
surgical risk and reduce post-surgical complications. The first device in the
series, The Kalangos® ring, received the CE Mark in March 2005. BIORING is
currently working on obtaining the FDA approval for this device
INTRODUCTION
The Kalangos® ring
was developed for pediatric annuloplasty to preserve the growth potential of
the child's heart. It is also suitable for adult annuloplasty by extension.
This now commercially available device made of biodegradable polydioxanone
induces the growth of autologous fibrous tissue that reinforces the deficient
annulus. The good functioning of the native, or repaired valve depends on
coaptation capacity of its leaflets. Annuloplasty rings have been used since
1968 to remodel the shape, correct the dilatation, and consolidate the repair
of heart valves by improving coaptation of the valve's leaflets during systole.
The further understanding of the three-dimensional geometry of the native valve
annulus during the normal cardiac cycle lead to the evolution of the rings from
the first rigid, planar stainless steel-based Carpentier ring to the fexible
Duran ring and to the more recent Cosgrove-Edwards bands. All these devices,
which actually fulfil the requirements of the application on adults, do not
allow the further growth of the native annulus if implanted in children.
Indeed, implantation
in growing hearts could result in a stenotic effect which could worsen with
time. For this reason, these current traditional rings do not exist in
pediatric sizes (under 26).
A
NEW CONCEPT IN ANNULOPLASTY VALVE REPAIR
The above
considerations were the driving elements for the development of a new concept
in annuloplasty valve repair: the future device had to allow growth of the
native annulus. Based on some encouraging results reported in annoloplasty
practices performed in the pediatric population with different biodegradable
materials and especially polydioxanone1-3, Bioring (Lonay, Switzerland) has
developed the Kalangos® mitral and tricuspid rings, which are biodegradable
annuloplasty devices made of polydioxanone. These advanced devices, do not work
like traditional rings. Indeed, the device does not provide a mechanical
support, except in the first short period following implantation, but induces
the creation of endogenous fibrous tissue which will take on this function
subsequently. Moreover, it was designed to facilitate its implantation. The
device is introduced within the native annulus and simply secured to the
anterior and posterior trigones by knotting the integrated monofilament sutures
equipped with crimped stainless steel atraumatic needles. This intra-annular
implantation prevents the device from being in contact with blood. This avoids
thromboembolic complications which require systemic anticoagulation therapies
until the endocardium covers the traditional rings sutured on the native
annulus. In addition, Bioring's device is solely composed of materials that can
be used in presence of endocarditis. In order to preserve the native annulus
growth potential in children, the non-resorbable suture that is incorporated in
the polydioxanone segment, in order to prevent further degenerative dilatation
of the annulus in adults, is cut in pediatric sizes of the ring under 26.
Ultrasound imaging follow-up of the first implantations performed on animals
demonstrated the preservation of the valve's functional efficacy and of the
ventricular contractility while allowing the physiological growth of the
orifice. This was revealed by measures of the valve orifices on the sacrificed
pigs which had seen their body weight increased by an average of more than 500%
over a year. Six months or more following implantation, a fibrous autologous
tissue was developed in all dissected hearts, in replacement of the implanted
polydioxanone device, resorbed by hydrolysis. Moreover, it was discovered that
the fibrous tissue continues on growing for a few months after complete
resorption of the device. The newly grown fibrous tissue remodells the annulus
and prevents it against redilatative stretch without interfering with its
dynamical physiological motion.
CLINICAL
STUDIES AND TRIALS
The preliminary
clinical study that focussed on pediatric population gave positive outcomes and
confirmed the results obtained in the animal trials. This demonstrated the
biodegradable device's main feature for pediatric applications: the
preservation of the growth potential of the native annulus4. In the frame of a
clinical trial performed between April 2004 and May 2006, 111 patients affected
by valve insufficiency, mostly of congenital, degenerative or rheumatic origin,
received a mitral and/or a tricuspid Kalangos® ring. The patients included in
this investigation were comprised between one and 75 years of age; 51 were aged
16 or less and 60 were aged 17 or more on the implantation date. Among them, 57
(51.3%) patients were
female and 54 (48.7%)
were male. This population was monitored with a mean follow-up of
approximately 10
months. The benefits of the valve repair with Bioring's biodegradable
annuloplasty device were assessed in terms of NYHA Grade for the 105 patients
in whom the follow-up was complete. They were immediately tested post-op and
monitored at 6, and 12 months. This evaluation was utilized as it is one of the
most commonly used scoring systems worldwide. It can be seen that all patients
fully recovered and are presently scored Grade 0 or Grade 1. Moreover, in this
study it is also demonstrated that the degradation of the polymeric segment of
the device occurs without any observable consequences for the patient. In
conclusion, the Kalangos® ring is a new biodegradable device that has proven to
be safe and efficient. Moreover it is the only commercial device available in
pediatric sizes for orrecting,
remodelling the shape, reinforcing, and restoring the function of the valves'
annuli, that preserves the native annulus growth potential in children. The
tissue-growth properties associated with the intra-tissular implantation of
this device introduce a completely new concept in annuloplasty.

facts as enumerated in the case.

concept at length in terms of Biodegradable principle.
Case -3 --Bone Substitutes to replace Transplantation?
INTRODUCTION
An osteoconductive
and osteoinductive biphasic ceramic replacement for bone loss could be an
alternative to grafts. The safety and efficacy of this material has been shown
in preclinical and clinical trials, demonstrating its suitability. Tumours,
bone cysts and traumas, as well as osteomyelitis and osteolysis, can cause
massive bone loss. The primary method used today for filling such defects is
autogenic or allogeneic bone transplantation. As both approaches are associated
with considerable problems there is an ongoing critical debate as to whether
these procedures should still be considered the treatments of choice. Autogenic
bone transplantation, for instance, is always associated with another surgery.
For the patient, the surgical removal of graft material means additional stress
and a higher postoperative morbidity due to local complications. In addition,
the amount of graft material that can be harvested from the patient’s own body
is limited. Economic analyses provide additional arguments for challenging the
use of autogenic bone material. Given the extended duration of surgery, the use
of autogenic bone grafts involves higher costs. Although allogeneic bone
transplantats have the advantage of higher availability,
their inherent
antigenicity is a major disadvantage.
BENEFITS
OF BONE SUBSTITUTES
Given the multitude
of problems associated with autogenic and allogeneic bone transplantation, the
search for bone substitutes similar to bone grafts in terms of biomechanical
strength and biological properties has intensified over the past few years.
Such materials should
support the bone healing process and ideally should be associated with
osteoconductive and
osteoinductive properties and biocompatibility. Apart from natural materials
obtained from corals or algae, there are inorganic materials such as ceramics
made of hydroxyapatite or tricalcium phosphate. Other materials include
xenografts and glass ionomer cements.
BIPHASIC
CERAMICS
The development of
Tricos® represents real progress in the field of bone substitutes. The idea
behind this bone substitute was to ensure structured, physiological formation
of bone substance. The biphasic ceramic containing hydroxyapatite (HA, 60%) and
beta-tricalcium phosphate (ß-TCP, 40%), fulfills these requirements in several
ways. This is used in combination with a fibrin matrix made of human plasma. In
the new material there is a balanced equilibrium between the quickly resorbable
beta-tricalcium phosphate and the slowly resorbable hydroxyapatite. ß-TCP has a
high osteogenetic potential and constitutes a source of P+ and Ca++ ions.
Simultaneously, with the progressive biodegradation of ß-TCP, biological
apatite crystals begin to form, gradually replacing the bone substitute
analogously to natural remodelling. Hydroxyapatite guarantees the long-term
stability of the material; it ensures that the bone substitute supports cell
adhesion in the long run, acting as a carrier. In its chemical structure the
substance resembles the bone’s biological apatite crystals, and it is only
mildly osteogenic. The new bone substitute has an interconnective pore system
consisting of micropores and macropores; the granules are 1–2mm in size . The
micropores less than 10μm in size provide for a rapid exchange of fluid and
ions by means of diffusion. With their size of 300μm–600μm, macropores permit
the adhesion and proliferation of osteogenetic cells. This ensures that the
bone substitute material is successively replaced, by cells spreading from the
periphery to the middle of the ceramic material
FIBRIN
MATRIX
In order to optimise
physiological bone regeneration the biological two-component matrix of
Tissucol/Tisseel® is
added to the inorganic material. The two-component matrix consists of
fibrinogen, plasmafibronectin, factor XIII and plasminogen as well as the
plasmin inhibitor aprotinin. The human thrombin contained as a second component
triggers the final step of physiological blood clotting, the conversion of
fibrinogen to fibrin. The completely resorbable fibrin is used in all surgical
fields. The fibrin matrix penetrates both micropores and macropores, and
provides high stability through adhesion to the walls of the bone defect.
Simultaneously, the fibrin matrix serves as a binding agent for the granules.
Its content of polymerised fibrin, fibronectin and growth factors helps trigger
cell proliferation and angiogenesis, and enhances wound healing. On a cellular
level the artificial bone induces signals similar to physiological material.
Diffusion of biological fluids into the ceramic´s micropores and macropores
triggers the release of calcium ions; macrophages, mesenchymal stem cells,
osteoblasts and osteoclasts will then enter the ceramic´s macropores. Cell
adhesion is followed by cell proliferation, and gradually, osteoclasts will
resorb the so-called artificial bone in a process similar to physiological
remodelling, while osteoblasts will build new bone material. Application of
Tricos is simple and straightforward. The preparation is ready for application
approximately two minutes after mixing the two components. Similar to a plastic
glue, the mixture can be applied with a spatula and used for anatomical reconstruction.
PRECLINICAL
AND CLINICAL DATA
The benefits of
biphasic ceramics combined with a fibrin matrix have been shown in many
preclinical and clinical trials over the past few years. The easy-to-use,
pliable material allows successful anatomical reconstruction, proving both
biocompatible and stable.
Histological
examinations reveal the polymerised fibrin to have a stable structure on which
ions crystallize, thus enhancing intrinsic osteogenic properties. Biopsis shows
that the material is progressively replaced by new lamellar bone within two or
three months. A retrospective long-term trial over 16 years supported the
material´s long-term tolerability, good bioactivity and high osteointegration
rate.
SUCCESSFUL
TREATMENT TRAIL
At Würzburg
Orthopaedic University Clinic further comprehensive clinical data on Tricos was
collected between 10/2004–08/2005. During a one-year clinical trial, bone
defects in a total of 17 patients aged between ten and 69 were treated using
the new bone substitute. The material was used for filling various bone defects
caused by benign tumours or tumour-like lesions. There were five patients with
benign bone tumours (enchondrome, chondromyxoid fibroma, chondroblastoma,
osteoma, osteoblastoma, osteoclastoma) and 12 with tumour-like lesions
(juvenile bone cyst, non-ossifying fibroma, eosinophilic granuloma,
intraosseous ganglion, fibrous dysplasia). The cysts were surgically removed
and each bone defect then filled with two to ten syringes containing 3.5cm3 of
Tricos, i.e. 7–35cm3 in total. During this one-year trial the bone substitute
proved both easy to use and safe. There were no
complications. The
long-term data after nine months showed that the biomaterial had successfully
integrated into the bone; resorption was not yet complete.

salient facts of the case.
2. Discuss at length
on the line of the salient features.
Case -4--Eliminating Latent TB
INTRODUCTION
Latent TB in
healthcare workers is a major threat to patients. Traditional tests have too
often been unable to detect the condition reliably. A new blood test looks set
to change this, which is good news for patients - and healthcare workers. In
December 2005 the New York Times reported that a nurse with active TB from a
New York City hospital had exposed 1,500 patients and infected four infants,
after 11 years of latency. As this case shows, the successful detection,
monitoring and treatment of Latent Tuberculosis Infection (LTBI) after
risk-assessment are crucial to reducing the number of active cases in patient
healthcare settings. The detection of latently infected persons has been the
objective of healthcare workers in patient-care settings in hospitals for
decades, but has often yielded unsatisfactory results. The blame for this has
been placed largely on the lack of a truly effective test for LTBI.
REPLACING
THE TST
The Tuberculin Skin
Test (TST), developed more than 100 years ago, has been the only tool available
for detecting LTBI, and the limitations of that procedure are well documented.
Although the TST may be a useful epidemiological tool, its poor specificity,
vulnerability to false positives and subjective interpretation mean that it
does not meet the standards required for today's medical decisions. As a
consequence of this poor medical return, programmes to detect LTBI, which could
include prophylactic treatment of the infection, have often been poorly
established, and control programmes themselves neglected. In May 2005 the US
Food and Drug Administration (FDA) approved the use of a whole blood test to
aid the diagnosis of LTBI. The new test, QuantiFERON(r)-TB Gold (QFT-G), also
eliminates the logistical
challenges of skin
testing: a simple venipuncture procedure followed by a standard, batchable
laboratory procedure is all that is required to obtain a definitive yes or no
response to the question of LTBI. New guidelines from the US Center for Disease
Control, published in December 2005, affirm that QFT-G can be used in all
situations in which a skin test is used, thereby recognising its potential as a
replacement for the TST.Unlike the TST, QFT-G is not confounded by BCG
vaccination or infection by non-TB mycobacteria. Furthermore, it eliminates the
logistical challenges of skin testing because of its simple application and
laboratory procedure.
A
NEW STANDARD
Hospitals around the
world have started to use QFT-G as their standard for LTBI testing. Those that
have implemented QFT-G programmes have recognised significant cost savings over
TST. These come mainly from significantly lower rates of positivity, leading to
reduced caseloads and elimination of working time losses for follow-up visits
to the occupational health office.
Case
Example: HOW A FALSE POSITIVE WAS ALMOST A REAL NEGATIVE
Keiko, a 19-year-old
Japanese exchange student in the USA, took a routine Tuberculin Skin Test (TST)
before beginning training to become a nurse. Although she showed no symptoms of
TB, the test gave a positive result of 15mm. Her doctor insisted that nine
months of preventive treatment with isoniazid was the standard of care
recommended by the Centers for Disease Control. However, Keiko argued that her
test was positive because of two BCG vaccinations she received as a child, and
denied exposure to active disease. A chest X-ray confirmed that she did not
have TB, but she was worried that her refusal of treatment might jeopardise her
entry into the nursing programme. Her doctor then found out that the local TB
programme used QFT-G and obtained a test for her. The result: no TB infection.
