| Abstract | BACKGROUND: The mechanisms under neurally mediated syncope (NMS) are not fully understood. This study aimed to assess the level of storage iron in children with different hemodynamic patterns in head-up tilt test. METHODS: Altogether 210 children (11.31±2.49 years) with syncope or pre-syncope treated between May 2008 and September 2010 were studied prospectively. Following history taking and physical examination, their levels of hemoglobin (Hb), hematocrit (Hct) and serum ferritin were measured. RESULTS: In the 210 children, 162 (77.1%) had NMS and 48 (22.9%) had syncope due to other causes. In the 162 children with NMS, 98 children were subjected to positive tilt test. The level of serum ferritin was significantly lower in the 98 children with NMS (P<0.001). The comparison of levels of Hb, Hct and mean cell volume (MCV) displayed no significant difference between the two groups. Reduced iron storage (serum ferritin <25 ng/mL) was found to be more prevalent in children with NMS (63% vs. 20%, P<0.001). Prevalence of iron deficiency was also significantly higher in children with NMS than in children with syncope due to other causes (27% vs. 6%, P=0.003). CONCLUSIONS: In head-up tilt test positive children with NMS, the level of serum ferritin should be evaluated. Low storage iron may be one of the underlying mechanisms of NMS. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
