Rectal Insufflation vs Major Autohemotherapy: A Comparative Review

Background: two routes for systemic ozone therapy

Systemic ozone therapy is delivered mainly through two routes. In major autohaemotherapy (MAH), a quantity of the patient's blood is withdrawn, mixed with a measured oxygen-ozone gas mixture and then reinfused. In rectal insufflation (RI), the same type of gas mixture is introduced directly into the rectum, where it is absorbed. Both approaches aim to trigger a controlled, mild oxidative response that the body adapts to over a course of treatment. A recurring question is how the two routes compare on safety and clinical effectiveness, and whether the clinical experience accumulated over decades holds up when judged against the standards of evidence-based medicine.

Study design: appraising more than a decade of clinical experience

This paper is a clinical evaluation and evidence classification. The authors gathered published clinical studies of the two systemic routes and appraised them critically against evidence-based medicine criteria. In total, the dataset covered more than 11,000 major autohaemotherapy treatments given to 577 patients and at least 47,000 rectal insufflations given to 716 patients. Each study was assessed for its methods and results and then classified according to recognised levels of evidence, so that the strength of the underlying research - rather than clinical impression alone - could be compared across indications.

Findings: both routes rated safe, with comparable effectiveness

Across the studies assessed, both major autohaemotherapy and rectal insufflation were reported to be safe, with a very low rate of adverse effects when standardised dosing was followed. The authors found both routes to be effective across a range of chronic inflammatory and circulatory conditions, and reported that rectal insufflation - the less invasive of the two - achieved results broadly comparable to major autohaemotherapy. On the evidence classification, several indications reached levels that the authors regarded as clinically meaningful rather than merely anecdotal.

What the authors concluded

The authors concluded that both major autohaemotherapy and rectal insufflation are established, well-tolerated forms of systemic ozone therapy, and that rectal insufflation offers a valuable, lower-burden alternative to major autohaemotherapy for suitable patients. They argued that the graded body of clinical evidence is strong enough to support wider clinical acceptance, and used the classification as a basis for their case that these treatments merit recognition and reimbursement.

Limitations of this study

This is an evaluation of existing studies rather than a new controlled trial, so its conclusions depend on the quality of the source material. Much of that material is observational or uncontrolled, with relatively few randomised controlled trials, and the studies varied widely in condition, dosing and how outcomes were measured. The pooled treatment counts reflect volume of clinical experience, not the rigour of individual studies. The authors are long-standing proponents of ozone therapy, and the paper does not add new primary patient data. Its findings are best read as a structured summary of the clinical evidence available up to publication rather than definitive proof of effectiveness for any single condition.
