TORRES RIVES, Bárbara et al. Autoimmune response in patients with genetic diseases and immune system deregulation. Rev haban cienc méd [online]. 2013, vol.12, n.1, pp. 35-47. ISSN 1729-519X.

Introduction: several genetic diseases with immunological disorder have been described. On the other hand autoimmune diseases have multi factorial origin and autoimmunity predisposition by genetic factors like histocompatibility principal complex has been demonstrated. Objective: describe autoimmune response disorder in patients with genetic defects and immune system deregulation. Material and Method: a descriptive study was carried out. Sample was constituted by 20 pacients with genetic defects and immune system deregulation, coming from Medical Genetic consult of Juan Manuel Márquez hospital, with sex distribution of 11 feminine (55%) and 9 masculine (45%) patients. Age interval was of 6 month and 21 years, for average of 6.9 years. Autoimmunity parameter studied were Rheumatoid factor and Anti double DNA chain antibodies determined by enzymatic immunoassay. Circulate immunecomplex determined by precipitation method and Antinuclear antibodies determined by indirect immunofluorescence. Results and Discussion: in evaluation of autoimmune response mayor positivity obtained was Circulate immunecomplex (40 %) and Rheumatoid factor (40 %) determinations, which may be correspond to an immune system hyper respond by recurrent infections consequence in patients. Antinuclear antibodies were present in 4% of patients. Anti double DNA chain antibodies, obtained in 35% of patients, can be produced in different clinical conditions and bay no pathological immune respond. Conclusions: investigation makes evident that patients with genetic defects and immune system deregulation have high frequency of alter autoimmune parameter.
