How healthy are chronically ill patients after eight years of homeopathic treatment?--Results from a long term observational study.

BACKGROUND: Homeopathy is a highly debated but often used medical treatment. With this cohort study we aimed to evaluate health status changes under homeopathic treatment in routine care. Here we extend former results, now presenting data of an 8-year follow-up. METHODS: In a prospective, multicentre cohort study with 103 homeopathic primary care practices in Germany and Switzerland, data from all patients (age >1 year) consulting the physician for the first time were observed. The main outcome measures were: The patients' perceived change in complaint severity (numeric rating scales from 0 = no complaint to 10 = maximal severity) and quality of life as measured by the SF-36 at baseline, and after 2 and 8 years. RESULTS: A total of 3,709 patients were studied, 73% (2,722 adults, 72.8% female, age at baseline 41.0 +/- 12.3; 819 children, 48.4% female, age 6.5 +/- 4.0) contributed data to the 8-year follow-up. The most frequent diagnoses were allergic rhinitis and headache in adults, and atopic dermatitis and multiple recurrent infections in children. Disease severity decreased significantly (p < 0.001) between baseline, 2 and 8 years (adults from 6.2 +/- 1.7 to 2.9 +/- 2.2 and 2.7 +/- 2.1; children from 6.1 +/- 1.8 to 2.1 +/- 2.0 and 1.7 +/- 1.9). Physical and mental quality of life sores also increased considerably. Younger age, female gender and more severe disease at baseline were factors predictive of better therapeutic success. CONCLUSION: Patients who seek homeopathic treatment are likely to improve considerably. These effects persist for as long as 8 years.

"Nothing in biology makes sense except in the light of evolution", wrote Theodosius Dobzhansky, one of the founders of the Modern Synthesis that led to the unification of evolutionary theory and genetics in the midst of the 20th century. Programmed cell death is a genetically regulated process of cell suicide that is central to the development, homeostasis and integrity of multicellular organisms. Conversely, the dysregulation of mechanisms controlling cell suicide plays a role in the pathogenesis of a wide range of diseases. While great progress has been achieved in the unveiling of the molecular mechanisms of programmed cell death, a new, and somehow puzzling level of complexity has recently begun to emerge, suggesting i) that several different self destruction pathways may exist and operate in parallel in our cells, and ii) that molecular effectors of cell suicide might also perform other functions unrelated to cell death induction and crucial to cell survival, such as cell differentiation, metabolism, and the regulation of the cell cycle. These new findings, with important physiopathological and therapeutic implications, seem at odds with the paradigm of programmed cell death derived from the studies of Caenorhabditis elegans, which led to the concept of the existence of selective, bona fide death genes that emerged and became selected for their sole capacity to execute or repress cell death. In this review, I will argue that this new level of complexity might only make sense and be understood when considered in a broader evolutionary context than that of our phylogenetic divergence from C. elegans. A new view of the regulated cell death pathways emerges when one attempts to ask the question of when and how they may have become selected during a timeline of 4 billion years, at the level of ancestral single-celled organisms, including the bacteria. I will argue that there may be no such thing as a bona fide genetic cell death program. Rather, in the framework of a model that I have termed the "original sin" hypothesis, I have proposed the existence of an initial pleiotropy of the molecular tools involved in the control and execution of self-destruction--an ancestral involvement in both pro-life and pro-death activities. I will discuss how this hypothesis may be reconciled with the C. elegans paradigm of programmed cell death. Finally I will discuss how an ancestral level of pleiotropic functions of the molecular tools involved in the control of cell death, aging and genetic diversification might have favored their initial selection, their constant availability for de novo selection, and their progressive propagation in most--if not all--species during the course of evolution.
