Although they have to be considered as a high risk group, guidelines for cancer screening in these patients are still lacking. Histological changes chronic atrophic gastritis may be detected years before the anaemia is manifested, and the progression of chronic atrophic gastritis to clinical anaemia is likely to years 1. A genetic predisposition to PA has been suggested 7,8.

We report a case of familial PA in 3 young adult triplets. Gastric biopsies were diagnostic of chronic atrophic gastritis. Some authors suggested anemi this pediatric presentation of PA might be the result of a genetically determined failure to secrete intrinsic factor or even the secretion of a defective intrinsic factor Autoantibodies to steroidogenic enzymes in autoinmune polyglandular syndrome, Addison’s disease and premature ovarian failure.

Endocrine complications of the adquired inmunodeficiency syndrom.

J Clin Endocrinol Metab ; 82 3: Megaloblastic anemia occurring simultaneously in white female monozygotic twins. Taking into account that PA is a known risk factor for gastric neoplasms, familial screening might be of relevance in case of twins, but systematic familial screening in all PA patients has to be accurately evaluated in gastrici setting of prospective studies.

The ethiology has drastically variated in the last century; being the origin almost exclusively tuberculous at the begining of and mainly autoimmune actually.

N Engl J Med,pp. Some authors suggested that this pediatric presentation of PA might be the result of a genetically determined failure to secrete intrinsic factor or even the secretion of a defective intrinsic factor 6. In fact, several authors have reported familial aggregability of PA 6and up to 20 percent of the relatives mainly first-degree female relatives of PA patients are also affected 1,9, Endoscopic gastric biopsies showed chronic gastritis without inflammatory infiltrate but with a marked focal reduction in the number of gastric glands, and without Helicobacter pylori infection.

Penrice J, Nussey SS. En este trabajo se describe la existencia de anemia perniciosa en 3 hermanas trillizas. Screening serology for celiac disease atTG, antiendomisial was also negative. Familial autoimmune haemolytic anaemia associated with rheumatoid gzstrico and pernicious anaemia. Intestinal metaplasia and atrophic gastritis associated with achlorhydria have been postulated as potencial pathogenic factors for the development of gastric cancer in patients with PA.

Hypoadrenalism Addison’s disease and antiphopholipid antibodies. However, macrocytic anaemia is not the only haematological presentation of atro-phic gastritis. Increased gastrinemia and low seric pepsinogen were also found.
