Introduction:

The Cuban national vaccination scheme has a coverage of more than 99% of the population, and includes the measles-mumps-rubella vaccine. Therefore, in the presence of a neuroinflammatory process, a broad intrathecal synthesis of measles, mumps and rubella antibodies takes place which makes it possible to conduct neuroepidemiological evaluations of the vaccination campaigns and the bias of extreme cases, from an immunological perspective.

Objectives:

Correlate the measles, mumps and rubella antibody index with associated autoimmune processes and in the identification of patients with possible immunodeficiencies in the study sample.

Methods:

An applied cross-sectional descriptive study was conducted of 42 children attending the emergency services of Havana children's hospitals in the period 2015-2018. The sample was divided according to the three antibody index intervals: smaller than or equal to 0.6, from 0.6 to 1.5, and greater than or equal to 1.5. Extreme segments were examined to detect patients with possible autoimmunity (greater than or equal to 1.5) and immunodeficiency (the interval below a standard deviation was taken as reference).

Results:

75% of the group with an antibody index greater than or equal to 1.5 was positive to the MRZ reaction, indicative of an active autoimmune disease. In the group with an antibody index lower than or equal to 0.6, the prevailing clinical status showed a prevalence of tumoral and infectious diseases associated to a high hospitalization index, a positive immunodeficiency test and low serum IgG levels.

Conclusions:

It is possible to identify pediatric patients with autoimmune disorders and suspicion of immunodeficiencies applying the strategy of neuroepidemiological evaluation of the measles, mumps and rubella antibody indices.
