The objective of this study was to report four clinical cases collected at the CHUR/OHG, and to review the literature. The study population consisted of two men and two women. The clinical manifestations were mainly neurological and hematological. The neurological signs were mainly paresthesia. One patient presented memory problems. On the biological level, macrocytic anemia and vitamin B12 deficiency were reported in two cases prior to treatment while the other two without serological assay of vitamin B12 were put on trial treatment. Anti-intrinsic factor antibodies were positive in three patients. The Schilling test was not used. Upper gastrointestinal endoscopy revealed atrophic fundic gastritis in all four patients who received treatment through intramuscular injection of hydroxocobalamin (vitamin B12). The evolution was favorable after one month of treatment in all cases. The literature review is dominated by clinical case reports, the largest cohorts of which are from the Maghreb.展开更多
