Comparison Between Rebamipide 2% Versus Autologous Serum in the Treatement of the Moderate to Severe Dry Eye Associate With Sjögren Syndrome. Pilot, Crossed, Controled, Randomized And Open Study

After having borrowed to participate in the study, we proceeded to the random assignment of each intervention as follow: the last 2 numbers of the clinical history, typical of the ocular surface office, were taken and they were placed in a list in order of lower to higher. Then, each of them was assigned to a number from a table of random numbers. The list was rearranged from lowest to highest using the assigned random number. Finally, the treatment was assigned by simple randomization without replacement. In this way, the subject with the lowest random number, the correspondence in the first treatment drawn. It was continued in the same way, respecting the order assigned by random numbers until completing the 21 subjects.

Three groups of 7 subjects each were formed in this way: treatment group or group Rebamipida (GR); standard treatment group or autologous serum group (GSA) and mixed group or serum and Rebamipide group (GSAR).

Before beginning with the assigned treatment, all the participants was started a period of wash-out of any medicine they were ussing, that least for two weeks. The participants were asked to suspend all the drops that they been used until then (antibiotics, corticosteroids, cyclosporine, artificial tears, autologous serum, etc.), and to place them using only artificial tears (sodium carboxymethyl cellulose). 1%, AUCIC 1%) four times a day in all cases. The purpose was to minimize the effect of the medication that could interfere with the results obtained from the treatments tested. The two week period also allowed the hemotherapy service to prepare the autologous serum for the subjects assigned to this group and initiate the treatment without delays.

Immediately after the washout period, the subjects began to receive the last treatments for 90 days.

After the first intervention cycle and with the objective of influencing the treatment cycle of the first treatment cycle, a second washing period of two weeks duration was carried out.
