[Complementary medicine: phytotherapy and soyaisoflavones as phytoestrogens].

After a introduction concerning complementary medicine, naturopathy and phytotherapy a general view of soy isoflavones as phytoestrogens will be given. In german speaking countries the term and topic naturopathy has a tradition of 150 years regarding theoretical development and practical use among lay people and health professionals in European culture. In contrary the term complementary medicine has been used for approximately 15 years in englisch speaking countries as a kind of collective name for European and Non-European medical cultures and traditions. Complementay medicine summarizes a huge variety of cultural, medical and qualitywise different medical methods and treatments which can be a contribution to conventional medicine. One of the oldest and intensly researched fields in European and Non-European complementary medicine is the use of herbal drugs (phytotherapy). Soy isoflavones serve as an example to show the differences between phytotherapy based on multicompounds and dietary supplements (neutraceuticals) based on monosubstances. The differing preparations of soy isoflavones are not phytotherapeutic medicine. A review of the experimental and clinical data concerning soy isoflavones as phytoestrogens for the prevention of cancer, menopausal complaints, osteoporosis or cardiovascular diseases indicates that the consumption of food containing phytoestrogens seems to be health protective. Yet, the relevance of supplementation of single phytoestrogens for an additional health effect is not sufficiently proven.

Meta-analysis: phytotherapy of functional dyspepsia with the herbal drug preparation STW 5 (Iberogast).

BACKGROUND: Despite a long-standing use of herbal drugs with dyspeptic symptoms, little attention has been paid to their clinical evaluation. AIM: To assess efficacy and safety of the herbal drug preparation STW 5 (containing, e.g. Iberis, peppermint, chamomile) in the treatment of functional dyspepsia. METHODS: Research in electronic databases, consultation of experts and of the producer identified STW 5 (Iberogast) as descriptor in six randomized-controlled trials. The raw data of three placebo-controlled studies which met the selection criteria, were reanalysed and pooled for meta-analysis; one reference-controlled study supported the safety analysis (STW 5: n = 199, control: n = 198). RESULTS: Pooled data showed verum (n = 138) to be more effective than placebo (n = 135) with regard to the severity of the most bothersome gastrointestinal symptom (P-value: 0.001, odds ratio: 0.22, 95% CI: 0.11-0.47). A fourth randomized-controlled trial showed no significant difference between STW 5 and cisapride. As to safety, adverse events were similar with verum and placebo; no serious adverse events occurred. DISCUSSIONS: From the point of view of efficacy and safety, the herbal medicinal product STW 5 appears to be a valid therapeutic option for patients seeking phytotherapy for their symptoms of functional dyspepsia.

[Natural remedies during pregnancy and lactation].

Up to date there is a lack of systematically gathered data on the use of natural remedies (phytotherapeutic, homeopathic, anthroposophic, spagyric, Bach and Schussler remedies) during pregnancy and lactation. The aim of this non-representative pilot study on 139 women, who came for delivery to three institutions between mid-1997 and the beginning of 1998, was to receive data about how often and within which spectrum natural remedies are used during pregnancy and lactation. During pregnancy 96% and within the lactation period 84% of the women consumed at least 1 natural remedy. Phytotherapeutic drugs were used most frequently. In contrast to the widespread use of natural remedies by pregnant women and nursing mothers in this study, little information on the effectiveness and possible risks is available. Therefore it seems necessary to examine and evaluate natural remedies used during pregnancy and lactation.

[Development of 'Ordnungstherapie' by Bircher-Benner in naturopathy of the 20th century].

BACKGROUND: The German term 'Ordnungstherapie' is one of the five therapeutics which defines naturopathy in German-speaking countries. OBJECTIVE: Who formed the term Ordnungstherapie in naturopathy and what does it mean? MATERIAL AND METHODS: Heuristics and criticism of literature of the 20th century as well as database research. RESULTS: Nowadays in German-language medical books Ordnungstherpie belongs to the five therapeutics which define European naturopathy. Yet, the interpretation ranges from health education to body-orientated forms of psychotherapy. The term Ordnungstherapie is often related with the German priest and hydropath Sebastian Kneipp, however, term and definition have been founded by the Swiss physician Maximillian Bircher-Benner. In 1937 he defined Ordnungstherapie as a complex concept of natural healing. It is based upon the rather nosological idea that health is order/harmony in the human body (physically, psychologically), the environment and the daily course. Illness occurs if disorder appears in one of these fields. The therapeutic setting of Ordnungstherapy is defined by 9 rules of conduct to maintain order, which include nutrition, the skin as an organ (exposure to light, air, water), breathing, movement, rhythm of life, and psyche. For all these aspects Bircher-Benner himself uses the terms somatotherapy (dietotherapy, sun and light therapy, hydrotherapy, exercise therapy, breathing technique, order of the rhythm of live) and psychotherapy. He chose these complementary methods subjectively after learning them from 1897 onwards in an eclectic manner and after gaining therapeutic empiricism. Nevertheless his ideas of the Ordnungstherapie correlate with the socio-political context of the 1940ies. CONCLUSIONS: The term Ordnungstherapie was introduced by Bircher-Benner as an umbrella term in 1937 to describe a complex concept of naturopathic therapies. It comprises, with certain limitations for phytotherapy, the therapies which nowadays define European naturopathy. Yet, in European naturopathy today Ordnungstherapie is mostly considered as one out of 5 constituents of naturopathy (dietotherapy, hydrotherapy, exercise therapy, phytotherapy, Ordnungstherapie). The classification of Ordnungstherapie as one of the 5 pillars of the Kneipp therapy was only done by Kneipp physicians in the middle of the 20th century and needs to be thought over.

Iberis amara L. and Iberogast--results of a systematic review concerning functional dyspepsia.

A systematic review referring to efficacy and tolerability of the herbal combination Iberogast (Iberis amara planta totalis, Chelidonii herba, Cardui mariae fructus, Melissae folium, Carvi fructus, Liquiritiae radix, Angelicae radix, Matricariae flos, Menthae piperitae folium) was performed in patients with functional dyspepsia. Three placebo-controlled trials and a reference-controlled trial showed a statistical significant and therapeutical relevant reduction of the gastrointestinal symptom-scores in 595 patients. The therapeutic efficacy was also found in one observational study (2267 patients). In accordance with the available evidence Iberogast seems to be an effective phytotherapeutic preparation to reduce the symptoms of dyspepsia yet, without central nervous side effects.

[From Swiss herbs to the global plant system and individual use--a biographic approach to Alfred Vogel].

BACKGROUND: Even 100 years after the birth of Alfred Vogel there is a lack of reliable data about his life as a non-doctoral therapist in the fields of naturopathy and phytotherapy. OBJECTIVE: Which documents about A. Vogel do exist, which facts do they prove about his career and which interpretations of his point of view of phytotherapy do they allow. MATERIALS AND METHODS: With the methods in medical history (heuristic, critic, interpretation) video, audio and written documents from the A. Vogel Museum and A. Vogel publisher in Teufen, the A. Vogel collection in the Museum in Aesch and the Bioforce AG in Roggwil have been examined. RESULTS: From 1923 to 1932 A. Vogel runs a grocer's shop or a herb and health-food store in Basel and later Bern, Zürich and Solothurn. The economic success of his health-food stores and his interest in the field of naturopathy enable him to take part in a training to become a 'natural doctor' and in 1933 he is registered by the 'Natural Doctors Association of Switzerland'. From 1935 on he is working as a nutritionalist in his own spa pension in Trogen and produces plant extracts in his 'Laboratory Bioforce'. From 1937 to 1957 he has a spa hotel in Teufen and is producer of extracts from fresh plants. He is able to travel all continents of the world from 1958 on, in order to observe customs and medical habits of different tribes. He writes about his findings in his own magazine and books. His knowledge about the usage of herbs in different cultures inspires his production of herbal extracts in his company. In 1963, to meet the increasing sales of his products, he founds the < > where he, until the early 1990s, takes part in the adjustment of the recipes to the new pharmaceutic-medical standards. CONCLUSION: Because of his work as a 'natural doctor' A. Vogel becomes one of Switzerland's best known non-doctoral therapists in the 20th century. The publication of his collected wisdom in a lay-like language is a contribution to the tradition and popularity in this field through which, as well as through the development of extracts from fresh plants, he becomes a promoter of phytotherapy.

[St. John's Wort (Hypericum perforatum): a plurivalent raw material for traditional and modern therapies].

St. John's Wort is one of the oldest and one of the best experimentally and clinically examined herbal remedies. In various medical cultures and medical systems--that is to say the regions of origin of Hypericum perforatum, like Europe, West Asia and North Africa--St. John's Wort has been used as a remedy for centuries. Preparations from St. John's Wort not only represent medical traditions but also ways of thinking, ideas and experiences from naturopathic healers (non-physicians) as well as patients. The complex multicompound with its evolutionary and coevolutionary developed composition and structure acts as a varied raw material for the production of quantitative and qualitative dissimilar remedies, which are multicompounds themselves. They differ not only analytically but also quite often in their effects. The certain and potential spectrum of internal and external uses includes gastrointestinal complaint and illness, skin disease, mucosal lesion, superficial injury, depressive upset and depression, somatoform disorders, restlessness, nervosity, convalescence, exhaustion, sleep disturbance and nursing treatment. The plurivalent character of the multicompound even enables a broad spectrum of activity. This might justify to prefer St. John's Wort to other drugs in a wide range of treatments: In tumor patients with depression the antioxidative effect and the experimentally documented induction of apoptosis could mean an additional advantage, and in depressive patients with coronary heart disease the same applies to the anti-inflammatory and antioxidative effects.

[Iberogast: a modern phytotherapeutic combined herbal drug for the treatment of functional disorders of the gastrointestinal tract (dyspepsia, irritable bowel syndrome)--from phytomedicine to "evidence based phytotherapy." A systematic review].

Iberogast is a complex herbal preparation. As a fixed drug combination (9 constituents) it is composed of a fresh plant extract of Iberis amara and of extracts of 8 other dried herbal drugs ( Chelidonii herba, Cardui mariae fructus, Melissae folium, Carvi fructus, Liquiritiae radix, Angelicae radix, Matricariae flos, Menthae piperitae folium). The pharmacological effects as well as the therapeutic effectiveness, tolerability, and toxicity of Iberogast were experimentally and clinically recorded and documented using modern investigation tools. Both the experimental as well as the clinical studies indicated a regulatory influence of Iberogast on the whole gastrointestinal tract by a special dual action. While the included extracts of the dried herbal drugs have mainly spasmolytic properties, the fresh plant extract of Iberis amara has a tonic effect on the gastrointestinal tract. Depending on the predistension of the gastric or intestinal wall, the tonic or the spasmolytic effects of Iberogast prevail. Both the fresh plant extract of Iberis amara and the combined preparation of Iberogast were found to be toxicologically safe in therapeutically effective doses. For the estimation of the clinical effectiveness a systematic review was performed (data research: January 1970 to September 2002). As shown in controlled (according GCP standard) as well as supportive and uncontrolled clinical studies, the symptoms of functional dyspepsia and of irritable bowel syndrome (one controlled study and one observational study) could be significantly reduced by these herbal preparation in comparison to placebo. Two trials comparing Iberogast with the prokinetics metoclopramide and cisapride demonstrated a comparable therapeutic effectiveness of the herbal preparation and the prokinetics in the treatment of dyspepsia. Adverse events were rare and, with respect to frequency and spectrum, partly the same as found with placebo. Another advantage of Iberogast is that it targets only the gastrointestinal tract and the enteral nervous system, but not the central nervous system. Because of its special dual action, its clinically proven effectiveness, and its good tolerability, Iberogast may be a drug of first choice in the treatment of functional gastrointestinal diseases and their corresponding symptoms.

Acute renal allograft dysfunction secondary to suprarenal arterial stenosis: a case series and review of the literature.

Stenosis of vessels proximal to the renal artery is an unusual cause of allograft ischemia. We report four patients who had such 'suprarenal' arterial stenoses leading to graft dysfunction that was reversed with revascularization. We additionally review the existing literature on this entity, outline the etiologies of such stenoses, as well as discuss the surgical and non-surgical therapeutic options in patients with this uncommon cause of allograft dysfunction.

Cytokine and T cell receptor gene expression at the site of allograft rejection.

Intragraft cytokine and T cell receptor gene expression was analyzed in rejecting renal allografts by polymerase chain reaction (PCR). Message for IL-1 beta, IL-6, and TNF-alpha was detected in nephrectomy tissue with pathological evidence of acute or chronic rejection. Similarly, mRNA for both IL-6 and TNF-alpha was present in renal biopsies from acute rejecting kidneys. IL-2R, IL-4, and IL-5 mRNA was present in both rejecting and rejected kidney allografts, indicating that these cytokines may play a role in ongoing renal allograft rejection. Conversely, IL-2, IL-7, and IFN-gamma message was detected infrequently. In order to address the diversity of T cells in rejecting kidneys, we have analyzed the clonality of the TcR present within the allograft tissue. Rearranged TcR genes were identified in all allografts examined (n = 16) indicating the presence of T cells bearing the alpha/beta TcR. We have determined that there is a heterogeneous infiltration of T cells in the rejected allograft with TcR representing x = 7.47 +/- 2.4 families rearranged in samples obtained from nephrectomies, whereas x = 5.33 +/- 0.58 families were detected in samples obtained from biopsy tissue. These data indicate that (1) cytokines are produced locally which may contribute to graft cell destruction, (2) the heterogeneity of intragraft T cells during kidney allograft rejection may exist because nonspecific lymphocytes have been recruited to the site by locally produced cytokines or because T cells are responding to multiple epitopes or multiple donor antigens. Detection of intragraft cytokines and TcR may prove useful in elucidating the mechanism of rejection and therefore lead to improved immunosuppression.

Improved results with combined donor-specific transfusion (DST) and sequential therapy protocol.

A combined DST-sequential CyA therapy protocol has been described that results in optimum graft survival for 1- and 2-haplotype mismatched living related donor-recipient combinations. In addition to the excellent graft survival obtained through 4 years, lower prednisone and CyA dosage levels are achieved with significantly decreased infection rates during the posttransplant period.

Inability of cyclosporine to completely prevent the recurrence of focal glomerulosclerosis after kidney transplantation.

From January 1984 through July 1986, 15 patients with biopsy-proven focal glomerulosclerosis (FGS) underwent kidney transplantation. Following transplantation, all patients were immunosuppressed with cyclosporine and prednisone. There were 8 men and 7 women with a mean age of 33 years (range, 16-47 years). Five patients (33%) had recurrence of FGS. Two patients had received kidneys from HLA identical siblings, and 3 patients were transplanted with cadaveric kidneys. In 4 out of 5 patients, the recurrence of FGS occurred within 3 months of transplantation. Of the 2 graft losses in this group, one was from recurrence of FGS. Ten patients followed for a mean of 25 months did not develop recurrence of FGS. No graft loss occurred in this group. Three patients with end-stage renal disease of unknown etiology were found to have FGS in the renal allograft and were presumed to have recurrence of FGS. All 3 patients developed the nephrotic syndrome following transplantation, and 1 patient has had progressive renal failure. Cyclosporine did not prevent the recurrence or the clinical manifestations of FGS following kidney transplantation. Additional studies are needed to determine if cyclosporine is effective in certain subgroups of patients with FGS.
