In systemic lupus erythematosus, clinical trials have produced controversial information about the role of PRL. Some results find association between serum PRL levels and disease activity. In contrast, other authors did not find this. Recently, autoantibodies against prolactin in SLE patients have been described. One hundred percent of SLE patients with anti-PRL autoantibodies had hyperprolactinemia (hPRL) and 31.7% of the SLE patients classified with idiopathic hPRL had anti-prolactin antibodies. A similar result was found in 103 pediatric SLE patients. The patients with idiopathic hyperprolactinemia and anti-PRL autoantibodies had less clinical and serological lupus activity than the SLE patients with idiopathic hyperprolactinemia, but without anti-PRL autoantibodies. <\/jats:p><jats:p> This evidence suggests that anti-PRL autoantibodies or the complex with any other molecule, like macroprolactinemia (big-big PRL) could have attenuated biological activity and this could explain why some clinical studies did not find any association between serum PRL levels and disease activity in SLE patients. However, studies in vitro have shown normal or elevated biological activity in Nb2 cell lines using PRL from serum with anti-PRL autoantibodies from patients with or without autoimmune diseases. <\/jats:p><jats:p> Several conclusions could be drawn. One is that while a set of hyperprolactinemic SLE patients display autoantibodies against PRL, it is not clear what role these autoantibodies play in the whole system. However, until now, we knew that the patients with antibodies to PRL lacked the clinical symptoms of hyperprolactinemia such as menstrual disturbances and\/or galactorrhea and show less clinical and serological lupus activity. <\/jats:p>","DOI":"10.1191\/096120301717165001","type":"journal-article","created":{"date-parts":[[2003,11,12]],"date-time":"2003-11-12T12:45:16Z","timestamp":1068641116000},"page":"757-761","source":"Crossref","is-referenced-by-count":16,"title":["Analysis of anti-prolactin autoantibodies in systemic lupus erythematosus"],"prefix":"10.1177","volume":"10","author":[{"given":"F","family":"Blanco-Favela","sequence":"first","affiliation":[{"name":"Immunology Research Unit, Paediatric Hospital, National Medical Center                         \u2018Siglo XXI\u2019, Instituto Mexicano del Seguro Social,                         M\u00e9xico City, M\u00e9xico; Immunology Research Unit,                         Paediatric Hospital, National Medical Centre Siglo XXI, IMSS, Av.
