Let's start with the main goals of this quite expensive method of treatment:
1. Complete elimination of the defective immune system, the main cause of the disease.
2. Launching a new immune system, absolutely without any traces of the disease.
To achieve the first goal, we need a high-dose chemotherapy and what is more important, effective and safe applying of this chemotherapy.
Otherwise, this treatment has no difference from
traditional therapy, where you're unable to get rid of the disease and have to continue taking pills forever.
At first glance, the both protocols look the same, total load of Cyclophosphamide also the same, but the main difference is in applying chemo:
Our conditioning regimen suggests 50 mg. per kg. weight continuously for a 4-day course, and what is the most important:
without interruptions! The conditioning regimen in Mexico is different, the first injection of Cyclophosphamide 100 (mg per kg of body weight), and then you have a break for a whole week until the second injection.
The fact is that after a single intravenous administration, the content of Cyclophosphamide in the blood plasma tends to rapidly decrease during the first 24 hours.
Studies show that after 72 hours it is still possible to detect their content in the blood, but this amount becomes negligible.

Consequently, after the first administration of Cyclophosphamide, the pharmacological effect does not have time to develop, and over the course of a week (168 hours), all Cyclophosphamide is safely eliminated from the body.
Only 4 days of continuous immunosuppression leads to neutropenia. In this state, you simply have no chances to survive outside the aseptic unit.
The «Mexican method» conditioning regime is more a formality, they split the chemo into two batches of two sessions one week apart. After each session you are able to return to the hotel or go sightseeing.
Therefore, people planning HSCT in Mexico should realize, that carried procedure can partially reduce the disease, but definitely can't eliminate it. It is important!
Those who did not realize that, after several years of observing negative dynamics, comes to us in order to perform a real HSCT (HDIT with AHSCT), in accordance with the original protocol.
