to fill gaps concerning theoretical models and
scientific basis. Such models make it possible to
overcome some of the inconveniences of clinical
trials for instance placebo effect, ethical issues,
duration and high costs; moreover they constitute a
vast and cheap source of biological material,
essential to perform a large number of experimental
repetition.
The main objective of the research was to give
novel insights on the not yet clarified mode of action
of homœopathic treatments and to provide reliable
information on their efficacy.
The plant-based model considered was the
“wheat growth model”. A total of 560 common
wheat (Triticum aestivum L.) seeds were used to
carry out the study; part of the seeds were stressed
with As2O3 0.1% to reduce germination and amplify
the effect of homœopathic treatment. The seeds
were been equally subdivided into four
experimental groups: control (non-stressed seeds
grown in distilled water); treated control (non-
stressed seeds grown in As2O3 45x); poisoned
(stressed seeds grown in distilled water); poisoned-
treated (stressed seeds grown in As2O3 45x). After 7
days of incubation seedlings were collected for
molecular analysis. Total RNA isolated from
seedling samples were used for microarray analysis
in order to study changes in gene expression over
different treatments. Subsequently, statistical and
bioinformatic analyses were performed to classify
genes in “induced” or “repressed” and to assign
them a supposed function. Comparative analyses
highlighted the particular effect of As2O3 45xin
stressed seeds. Real time PCR was performed to
validate gene expression profiles: data obtained with
microarray and real time PCR were found to be well
correlated.
This research provided novel insights on the
mode of action of homœopathic potencies and
constitute an important breakthrough in the study of
the molecular responses triggered in wheat by ultra-
high diluted treatments.
10. Sensitivity and likelihood ratio of symptoms in
patients with good therapeutic response to
Lycopodium, compared to patients with good
response to treatment with other homœopathic
medicines. Retrospective study
EIZAYAGA, José Enrique and CANAN María
Clara (HOM. 103, 1/2013)
Background and aims: Availability of reliable
guiding symptoms in order to accurately prescribe
homœopathic medicines is a matter of critical
importance. Recent published work has highlighted
the likelihood ratio (LR) of symptoms as an
objective manner of addressing the question. The
aim of the present study is to establish the sensitivity
and LR of 35 common symptoms attributed to
Lycopodium, comparing good respondents to this
medicine to good respondents to other medicines.
Methods: In order to select which symptoms to be
evaluated, a survey was conducted with 110
homœopaths-47 from Argentina and 63 from other
countries- inquiring on the 10 most important
symptoms they use to prescribe Lycopodium in their
clinical practice. In a second phase of the study, the
presence of selected symptoms was retrospectively
assessed in the clinical records of the first visit of
patients to the Homœopathic Outpatient Clinic of
the Faculty of Medicine of Maimόnides University.
Patients with one only visit, no homœopathic
prescription or more than one prescription, less than
18 or more than 65 years old or acute complaints
were excluded. Only patients with good response
attributable to the homœopathic treatment were
included for analysis. Sensitivity (S) -or prevalence
in Lycopodium responding cases- Likelihood Ratio
(LR) and their 95% Confidence Intervals were
calculated for each symptom.
Results: Twenty-five homœopaths answered the
survey and 35 symptoms were selected for the study,
875 records were assessed -about one fourth of the
archive- and 564 excluded for different reasons. Of
the remaining 311, 76.6% were females and 28.6%
were prescribed Lycopodium. Females were more
frequently prescribed Lycopodium than males
(32.8% vs. 15.1%, P 0.003). Good response was
seen more frequently in Lycopodium cases than in
other medicines cases (75% vs. 62%, P <0.027).
205 good responding cases were included for
symptoms analysis. LR of symptoms’ prevalence
were calculated between Lycopodium (n=67) and
other medicines (n=138) good responding cases.
A group of symptoms emerged as being
important pointers to Lycopodium prescription,
having high sensitivity and higher than 1 statistically
significant LR; anger from (or intolerant of)
contradiction (S 50.7%, LR 2.7), dictatorial (S
40.3%, LR 7.9), lack of self-confidence (S 32.8%,
LR 3.2), irritability on waking (S 20.9%, LR 4.1),
irritability before menses (S 28.2%, LR 3.9),
helplessness (S 20.9%, LR 2.2), haughty (S 10.4%,
LR 4.8), anticipation (S 31.3%, LR 2.1),
conscientious (S 32.8%, LR 1.6), desire of
chocolate (S 22.4%, LR 2.1), desire of sweets (S
46.3%, LR 1.6) and abdominal distention after
eating (S 34.3%, LR 2.2). the symptom
