  Abstract 

Objective : To elicit the pathogenetic response of the drug Cyclosporin in homoeopathic potencies on apparently healthy human beings.
Material and Methods : The drug Cyclosporin was proved by the Central Council for Research in Homoeopathy through double-blind placebo-controlled trial. The study was conducted in two centres. The drug was proved in two potencies (6C and 30C) on 50 apparently healthy volunteers who were selected after conducting pre-trial medical examinations by the medical specialists and routine laboratory investigations. In the first phase the volunteers were given 56 doses (4 doses per day for 14 days) of placebo. In the next two phases, 56 doses (4 doses per day for 14 days) of each potency or placebo were consumed. The symptoms generated during the trial period were noted by the volunteers and elaborated by the proving masters. The data obtained from the two centers were compiled at proving-cum-data processing cell at Central Council for Research in Homoeopathy (CCRH) headquarters after decoding.
Results : Out of 50 provers, 33 were on actual drug trial and 17 were on placebo. Eleven provers manifested symptoms. The drug was able to produce symptoms in each potency in most parts of the body.
Conclusion : The pathogenetic responses elicited during the proving trial expands the scope of use of the drug Cyclosporin and will benefit the research scholars and clinicians. These symptoms will carry more value when verified clinically.

  Introduction Top


Cyclosporin is a medicine of conventional system. Clinical indications for Cyclosporin are kidney, liver, heart and other organ transplantation, rheumatoid arthritis, and psoriasis (Faulds et al., 1993). In psoriasis, Cyclosporin is indicated for treatment of adult non-immuno-compromised patients with severe and disabling disease in whom other systemic therapies have failed (Linden and Weinstein, 1999). Because of its mechanism of action, there is a theoretical basis for the use of Cyclosporin in a variety of other T-cell mediated diseases (Faulds et al., 1993). Cyclosporin has been reported to be effective in Behcet's acute ocular syndrome, endogenous uveitis, atopic dermatitis, inflammatory bowel disease and nephritic syndrome, when standard therapies have failed. [1]

Cyclosporin suppresses some humoral immunity but is more effective against T cell-dependent immune mechanisms such as those underlying transplant rejection and some forms of autoimmunity (Kahan, 1989). It preferentially inhibits antigen-triggered signal transduction in T-lymphocytes, blunting the expression of many lymphokines, including interleukin (IL)-2, as well as expression of antiapototic proteins. [2] Cyclosporin is a second-line drug in autoimmune diseases like severe rheumatoid arthritis, uveitis, bronchial asthma, inflammatory bowel disease, dermatomyositis etc. , and in psoriasis, especially to suppress acute exacerbations. [2] Cyclosporin A (CyA) has a selective action on the T series of lymphocytes. [3]

Keeping in view the action of Cyclosporin most markedly on the immune system it was felt necessary to elicit its pathogenetic effects in homoeopathic potencies. So the Central Council for Research in Homoeopathy undertook its systematic Homoeopathic Pathogenetic Trial (HPT) as per the approved protocol.

Description

Cyclosporin is a cyclic polypeptide consisting of 11 amino acids, produced as a metabolite of the fungus species Beauveria nivea (Borel et al., 1976). [1] It was introduced as a highly selective immunosuppressant, and has markedly increased the success of organ transplants. [2] About 40% of Cyclosporin is absorbed from the gastrointestinal tract and is extensively metabolised in the liver, mainly by the cytochrome P450 3A system; the t΍ is 27 h. [4] Since Cyclosporin is lipophilic and highly hydrophobic, it must be solubilised for clinical administration. [1]

Toxicity/Adverse Reactions

The principal adverse reactions to Cyclosporin therapy, as per the literature reports, are renal dysfunction, tremor, hirsutism, hypertension, hyperlipidaemia and gum hyperplasia (Burke et al., 1994). Nephrotoxicity is limiting and occurs in the majority of patients treated. Hypertension may occur in approximately 50% of renal transplant and almost all cardiac transplant patients. [1]

Cyclosporin constricts the pre-glomerular afferent arterioles and reduces glomerular filtration; acute or chronic renal impairment may develop if the plasma concentration consistently exceeds 250 mg/l. Other adverse effects include gastrointestinal reactions, hepatotoxicity, hyperkalaemia, hypertrichosis, gingival hypertrophy and convulsions. The clinical syndrome of thrombotic thrombocytopenic purpura may follow Cyclosporin therapy. [3]

Potencies Used

6C and 30C.

Objective

To elicit the pathogenetic response of the drug Cyclosporin on apparently healthy human volunteers in homoeopathic potencies.

Study Design

The study was a randomized, double-blind, placebo-controlled trial.

Participants and Setting

The proving was conducted at two centers: Central Research Institute, Noida during 2009-10 and Drug Proving Unit, Bhubaneswar during 2008-09. Totally 50 apparently healthy volunteers from the above mentioned two centres total 33 apparently healthy volunteers from above mentioned two centers of age group between 19 and 29 years, comprising 12 males and 38 females were enrolled. Two provers dropped out at Bhubaneswar centre.

Drug (Intervention)

Cyclosporin was procured in 6C and 30C potencies from M/s HAPCO Pharmaceuticals, Kolkata, India, a Good Manufacturing Practice compliant firm. Globules (size 30) were medicated with these attenuations at the Council's headquarters and sent to drug proving research units in coded phials (verum), along with placebo (control).

Placebo

Placebo was made up of plain globules (size 30) moistened with plain dispensing alcohol (unsuccussed), and was therefore indistinguishable from verum.

Methodology of Proving

Before commencing the study, all provers were screened strictly by the experts, and apparently healthy provers of age between 18 and 45 years, consisting of both males and females, were included in the drug proving trial. Pregnant and lactating mothers were excluded. 'Written informed consent' was obtained from each volunteer before starting the proving. Pre-trial Medical Examinations (PME) and Terminal Medical Examinations (TME) of the volunteers were carried out by General Physicians, Psychiatrists, Cardiologists, Ophthalmologists, ENT specialists, Dermatologists, Gynaecologists and Radiologists and their routine laboratory investigations were done at the centers to ascertain their health status. After the recommendation of experts, healthy volunteers were enrolled in the Homoeopathic Drug Proving Programme. The study was conducted at the two centres mentioned above. According to Central Council for Research in Homoeopathy (CCRH) Drug Proving Protocol, the sample size included 30% volunteers under the control group at each centre.

Out of the total 50 volunteers, 33 were kept on the drug (verum) and 17 on placebo (control) in all three phases. All the volunteers were assigned code numbers, and the coded drugs of different potencies (including placebo) were supplied in separate glass phials labelled with code numbers of the respective volunteers, keeping both provers and proving masters blind about what provers were consuming (drug or placebo).

The study consisted of three phases. Each phase consisted of 56 doses of coded drugs or placebo.

Phase 1: Placebo phase. It is useful in generating prover's response to placebo, and therefore, symptoms generated by the provers in this stage act as control for subsequent phases.

Phase 2: In the second phase, the proving was conducted with 6C potency.

Phase 3: In the third phase, the proving was conducted with 30C potency.

The volunteers were instructed to take four to six globules of a particular potency of the coded drug, four times a day, dry on the tongue and were also instructed to note down the details of their feelings/changes in mind and body after taking the coded drug in "prover's day book proforma" daily.

  • If no sign(s)/symptom(s) appeared
If no sign/symptom was observed, the volunteer noted down as "no symptom" with the date and time of intake of the respective dose of the drug/placebo.

  • If sign(s)/symptom(s) appeared
The volunteers were asked to stop the drug/placebo as soon as he/she felt any change or any sign(s) and/or symptom(s) developed during the trial. The volunteer noted down the sequence of the appearance of new sign(s) and/or symptom(s), their progress and the number of doses after which each sign or symptom appeared, with the date, time of onset and duration for which it persisted. The intake of drug remained suspended till the sign(s) and/or symptom(s) totally disappeared. Any change in the normal routine of the prover with respect to the daily habits pertaining to diet, living conditions, etc., or any treatment taken was also noted in the "prover's day book proforma."

After the disappearance of sign(s) and/or symptom(s) developed by the drug, the volunteer had to wait for a further period of 7 days before taking the remaining doses of that potency following the same dose schedule as stated above. In case of further appearance of new sign(s) and/or symptom(s), the same procedure as stated above was followed until the consumption of 56 doses of that potency by the volunteer. If the volunteer was experiencing the same symptom(s) what he/she had already shown, he/she was asked to stop the current quota and switch over to the next quota after a washout period of 14 days.

Each prover was interrogated by the proving master about the appearance of new sign(s) and/or symptom(s) or the progress of symptoms, and they were noted down in "Symptoms Elaboration Proforma" with respect to appearance and disappearance of symptoms, their location, sensation/character, modalities, concomitants, extension of symptoms, causation, clinico-pathological findings and other treatment taken.

Before commencing the administration of subsequent potencies (subsequent phase) of the drug, the volunteers remained on a washout/rest period (it should be a symptom-free period between two phases of drug proving in which a volunteer does not take the drug) for 14 days and started taking the next potency following the same procedure as mentioned above, until completion of 56 doses. The same procedure was followed for the third phase.

The symptoms recorded in prover's day book proforma were verified by the proving master and completed through further interrogation with the volunteers, with respect to their location/sensation/modalities/concomitants, if any, in Symptoms Elaboration Proforma.

During the course of proving, the volunteers were referred for specific laboratory investigation(s) to rule out any pathological cause for appearance of new sign(s) and/or symptom(s). Laboratory tests were performed to identify any correlation between the subjective and objective changes during the course of proving. The opinion of the experts (honorary consultants) was also obtained, wherever needed.

After completion of trial of all potencies, the volunteers underwent TME. On completion of all the respective quotas of the proving program, the compilation of data recorded in prover's day book proforma Symptoms elaboration proforma, pathological report sheets, and terminal medical examination sheets were analysed CCRH headquarters by the drug proving-cum-data processing cell. After decoding, the signs and/or symptoms experienced by the volunteers kept on the drug were separated from those experienced by the volunteers kept on placebo. The signs and/or symptoms, which were common to both the groups (i.e. placebo as well as drug groups), were not taken into consideration while compiling the symptomatology of the proved drug.

Management of Adverse Effects

A vial of antidote was sent with each quota to each centre. The proving master gave antidote to the volunteer if symptoms continued for a long time or their intensity was too much to cause discomfort. The proving master was also directed to take the advice of honorary consultants and to get laboratory investigations done, if required. During proving, no serious adverse events occurred.

Pathogenetic Effects

Pathogenetic effects (proving symptoms) are defined as all the changes in clinical events and laboratory findings reported by the volunteers during a HPT and recorded in the final report. The incidence of pathogenetic effects per volunteer is defined as the total number of findings observed in the trial divided by the total number of provers who developed symptoms. [5] So, the incidence in this proving was 2.45 per volunteer. The total number of symptoms produced by 11 provers was 27. Among these, 21 symptoms [Table 1] were produced during the second quota, i.e. by 6C, and 6 symptoms [Table 2] were produced during the third quota, i.e. by 30C.

Pathogenetic effects were deduced from the following:

  1. Comparison of symptoms developed in the placebo phase with the symptoms developed during the intervention phases (intra-prover comparison)
  2. Comparison of symptoms developed by the provers in the control group (for all phases) with those of provers in the actual drug trial (inter-prover comparison).

  Discussion Top


The drug was able to produce symptoms both in 6C and 30C. Maximum symptoms were produced by 6C potency. The drug was able to produce more symptoms of head and nose. Symptoms in head were marked by congestion, with surging of blood to head producing mild heaviness and bursting sensation. Throbbing also corroborated the hyperemic condition of head. Discharges from the nose had acrid character and produced itching and burning sensation. Amelioration from lying down can be considered as the general modality that was observed in head, nose, back and general muscular pains. Among the 11 volunteers who developed symptoms, 3 volunteers developed maximum symptoms in different systems.


  Conclusion Top


The symptoms produced during the trial will benefit the research scholars and clinicians. Those proving symptoms need verification through application in different Clinical Verification Trails and will add their value in prescription. Further observation of new clinical symptoms after its therapeutic use may enhance its applicability in day-to-day practice.
