  • Purpose: This study identified the factors that influenced the food-intake practices affecting iron deficiency anemia among Senegal mothers. Methods: The subjects were 155 mothers in Dakar, Senegal. We surveyed 21 questions concerning their knowledge of iron deficiency anemia, the perceived severity and perceived benefits, self-confidence, food preferences and food-intake practices during the period from December 4, 2017 to December 29, 2017. Results: The factors significantly related to food-intake practices affecting iron deficiency anemia included having a female head of household with male support (β=0.249, p=.003) and being in the 5th quintile of income level (β=0.386, p=.003). Conclusion: The results of regression analysis showed that the head of household and income level are factors that influenced the food-intake practices affecting iron deficiency anemia. Therefore, economic factors and the structure of the household must be considered to achieve success for Senegalese iron deficiency anemia projects.

  • Purpose: It is known that lactoferrin serves as a source of iron for H. pylori in gastric mucosa. This study was undertaken to investigate the relationship between lactoferrin and H. pylori infection coexistent with iron-deficiency anemia by determining the lactoferrin levels in gastric biopsy specimens, and by locating the major sites of lactoferrin expression, according to the presence or absence of iron-deficiency anemia. Methods: Fifty-five adolescents that underwent gastroduodenoscopy were divided into three groups: NL (n=19) for normal controls, HP (n=15) for patients with H. pylori, and IDA (n=21) for patients with H. pylori gastritis and coexisting iron-deficiency anemia. Histopathologic features were graded from to marked on the basis of the Updated Sydney System. The gastric mucosal levels of lactoferrin were measured by immunoassay. Immunohistochemical technique was used to allow identification of the location and quantification of the lactoferrin expression. Results: Lactoferrin levels in the antrum increased significantly, in proportion to, H. pylori density, polymorphonuclear cell infiltration, and chronic inflammation in the histologic specimens. Patients in the HP and IDA groups showed significantly increased mucosal levels of lactoferrin compared with that observed in the normal group (p=0.0001). The lactoferrin level in IDA group tended to be higher than that in the HP group (p=0.2614). The major sites of lactoferrin expression by immunohistochemistry were in glands and neutrophils within epithelium. Lactoferrin was stained weakly in NL, and strongly in HP and IDA. Conclusion: The lactoferrin sequestration in the gastric mucosa of IDA was remarkable, and this finding seems to give a clue that leads to the clarification of the mechanism by which H. pylori infection contributes to iron-deficiency anemia.

  • Background : Anemia is still the most common nutrient deficiency worldwide, especially in adolescence because of an insufficient supply of iron, an increased iron requirement due to accelerated physical growth and blood loss due to menstruation in girls. This study was designed to assess the anemia and serum iron status of middle school girls. Methods : Hematologic examinations, physical examinations and questionnaires were performed for middle school girls in 1990, 1997, 1999 and 2000. Anemia was defined as a serum hemoglobin level of less than 11.5 g/dL. Iron deficiency was defined as a serum ferritin level of less than 10 ng/mL. Iron deficiency anemia was defined as anemia plus one of the following; MCV less than 78 fL, Ferritin level less than 10 ng/mL or Transferrin saturation rate less than 10%. Results : There was no significant difference in mean Hb between urban and rural areas and decreases in mean Hb as with age. The prevalence of anemia decreased by year; 13.5% in 1990, 6.9 % in 1997, 6.0% in 1999, and 5.7% in 2000. It was high in high school girls(10.1% in 1997 and 12.6% in 2000). The prevalence of iron deficiency decreased by year; 36.1% in 1990, 13.9% in 1997, 13.3% in 1999, and 23.2% in 2000. It was 21.3% in 1997 high school girls and 37.8% in 2000. The prevalence of iron deficiency anemia(IDA) decreased by year; 10.0% in 1990, 4.6% in 1997, 8.3% in 1999, and 6.1% in 2000. It was 11.6% in 1997 high school girls and 18.6% in 2000. Conclusion : Although the prevalence of iron deficiency decreased during this period, the prevalence of anemia in the elder adolescence girls was high. Two things are recommended; first, it is necessary to screen for anemia in middle school girls and high risk groups, second, it is important to evaluate the knowledge of nutrition and to enforce effective nutritional education, leading to subjects receiving adequate nutrition.

A. 진성철결핍증(眞性鐵缺乏症) : 혁색소철(血色素鐵) 및 저장철(貯藏鐵)을 포함(包含)한 생체내(生體內) 전철분(全鐵分)의 부족(不足)된 상태(狀態)로서 실혈(朱血)에 의(依)한 것이 대부분(大部分)이다. 이 경우 철흡수(鐵吸收)는 증가(增加), 혈장철치(血漿鐵値)는 저하(低下), 철소실속도(鐵消失速度)는 증가(增加)되며 혈장철(血漿鐵) 교체율(交替率)은 항진(亢進) 혹(或)은 정상(正常)이다. B. 심(甚)한 염증성(炎症性) 질환(疾患) : 이 경우에도 혈장철치(血漿鐵値)의 저하(低下), 소실속도(消失速度)의 증가(增加), 교체율(交替率)은 정상(正常)보다 4배(倍)까지 증가(增加)할 수 있다. 골수(骨髓)에서 보다는 간(肝), 비(脾)와 같은 망내계(網內系)에 방사성철(放射性鐵)이 집결(集結)되는 것으로 보아 혈색소철(血色素鐵)보다는 저장철(貯藏鐵)이 관여(關與)되는 것이다. C. 원발성(原發性) 혈색소증(血色素症)(Idiopathic hemochromatosis) : 혈장철(血漿鐵)의 증가(增加)가 현저(顯著)하며 transferrin 농도(濃度)는 정상(正常)보다 낮으나 거의 대부분(大部分)의 철분(鐵分)으로 포화(飽和)된다. 철흡수(鐵吸收)는 증가(增加)되고 철소실속도(鐵消失速度)는 감소(減少) 되어 있으나 교체율(交替率)은 항진(亢進)되어 있다. 혈장철(血漿鐵)은 간(肝), 비(脾) 등(等)의 기관(器管)으로 저장집결(貯藏集結)되어 철저류(鐵貯溜)가 증대(增大)되므로 철이용증((鐵利用症)은 저하(低下)된다. D. 선천성(先天性) 무(無)$\ulcorner$트란스헤 린$\lrcorner$증(症)(Congenital atransferrinemia) : 방사성철(放射性鐵)을 이용(利用)한 진단방법(診斷方法)으로 Freiburg에서 7세(歲)의 소녀(少女)에서 발견(發見)한 증례(症例)인데 간(肝), 비(脾), 심(心)의 비대(肥大)가 임상적(臨床的)으로 인지(認知)되었고 중증(重症)의 철결핍상(鐵缺乏狀)을 검출(檢出)할 수 있었다. 철흡수율(鐵吸收率)의 상승(上昇), 혈장철치(血裝鐵値)의 감소(減少), 혈장철소실속도(血漿鐵消失速度)의 증가(增加), 혈장철교체율(血漿鐵交替率)의 상승(上昇) 및 적혈구(赤血球)에서의 철분이용율(鐵分利用率)의 저하(低下)를 ferrokinetic study에서 알 수 있었고 간(肝)에서 고도(高度)의 방사능(放射能)이 검출(檢出)되는 반면(反面), 비(脾)에서는 극소(極小), 골수(骨髓)에는 전(全)혀 방사능(放射能)이 들어가 있지 않았다. 이 증례(症例)와 같이 transferrin이 없으면 철분(鐵分)은 쉽게 조직(組織)으로 들어가 hemosiderin으로 저장(貯藏)되고 골수(骨髓)는 고도(高度)의 철결핍증(鐵缺乏症)을 나타내어 기관철침착증(器管鐵沈着症)과 철결핍성빈혈(鐵缺乏性貧血)이 동시(同時)에 나타나게 된다. 철대사장애면(鐵代謝障碍面)으로 보아 많은 미해결점(未解決點)이 남아 있으며 앞으로 자라나는 젊은 학도(學徒)들이 구명(究明)할 문제(間題)라고 믿는다.

  • Purpose: Iron deficiency anemia (IDA) is one of the most common nutritional problems, despite a recent improvement of nutritional status of infants and children. We assessed the risk factors for IDA in infants and vitamin D deficiency and IDA by nutrition analysis. Methods: We analyzed blood tests and evaluated 103 children with IDA and 123 children without IDA, 6-36 months of age, who were cared for in our hospital between March 2006 and July 2010. Nutritional analysis using Canpro was performed among breastfed infants 6~12 months of age who had been diagnosed with IDA and had detailed diet histories. Results: Breastfed infants accounted for 87.4% and 40.7% of the IDA and comparison groups, respectively. The IDA and comparison groups began weaning food at 6.4${\pm}$1.8 and 5.9${\pm}$1.3 months, respectively. In the IDA and comparison groups, 46.4% and 53.5% began to adapt to weaning food within 4 weeks, respectively. The most common reason for hospital care of the IDA group was respiratory symptoms constituting 36.2%. Only 18.6% visited the hospital for palloror anemia. The Canpro analysis, performed on 11 infants with IDA, showed that iron and vitamin D were <40% and 30% of recommended intakes, respectively. Conclusion: Weaning food should be started 4~6 months of age in breastfed infants. In infants at high risk for IDA and vitamin D deficiency, screening tests should be recommended. The high-risk infants may require iron, vitamin D fortified formula, or oral supplements.

  • Plummer-Vinson syndrome is a clinical entity characterized by dysphagia, iron deficiency anemia, cheilosis, glossitis, and cervical esophageal web, especially in middle aged women. Recently, the authors experienced a case of Plummer-Vinson syndrome. A 53-year-old female was admitted due to intermittent solid food dysphagia for 18 months. She had a 2 years history of iron deficiency anemia. On admission glossitis, fissures at the angle of the mouth, spoon nails, and iron deficiency anemia were noted. Esophagogram and esophagoscopic examination revealed thin walled concentric web at upper esophagus. Esophageal web was succefully teared by endoscopic balloon dilatation with subseguant improvement of dysphagia. Skin manifestations as well as anemia were markedly improved after oral iron replacement therapy.

  • Perianastomotic ulceration (PAU) rarely occurs after small bowel resection in infancy. Since the understanding of its pathogenesis is incomplete, an effective method of treatment has not yet been discovered. We report the first case in Korea of a 10-year-old girl with chronic iron deficiency anemia (IDA) and growth failure who was diagnosed with PAU at colonoscopy. Seven years were required to identify the cause of IDA. After surgical resection and revision of anastomosis, a close follow-up is being conducted due to the risk of recurrence. Here, we also review reports on 25 pediatric patients with PAU derived from a search of the English-language literature and describe the clinical features of PAU along with the results of treatment.

  • Purpose : Obesity and iron deficiency are common nutritional problems. Obese children are known to have iron deficiencies, but one presented opposite opinion in Korea. This study investigated the prevalence of obesity and iron deficiency in Incheon and the relationship between iron deficiency and obesity. Methods : Physical measurement and hematologic examinations were done a 764 healthy female students aged 14 to 15 years in May, 2005. Overweight was defined as a body mass index ${\geq}85th$ percentile. Iron deficiency was defined as serum ferritin <10 ng/mL. Iron deficiency anemia (IDA) was defined as serum Hb <12 g/dL and serum ferritin <10 ng/mL and/or transferrin saturation <16%. Results : 1) The prevalence of overweight was 24.4 percent (n=186), and that of obesity 16.5 percent (n=126). Ferritin and transferrin saturation was the lowest in the normal weight group. 2) The prevalence of iron deficiency and IDA was 18.7 percent (n=102) and 5.3 percent (n=41), respectively. 3) Iron deficiency was more common in the normal weight group compared with the overweight and underweight groups. Also, the non-obese had more iron deficiency and IDA than the obese. Conclusion : The prevalence of obesity in middle school girls could be higher in Incheon than in other regions, but there might be no difference in iron deficiency. However, iron deficiency was more prevalent in the normal weight group than in overweight group. The overweight group ate more food and gained more iron, so seemed to be less prevalent in iron deficiency than the normal weight group.

  • Objectives: The object of this study is to observe the possible ameliorating effects of Nokyongdaebo-tang (NYDBT) on the experimental subacute hemorrhagic anemia (SHA) in rats. Methods: In the present study, SHA in rats was induced by exsanguinations from orbital plexus, and ameliorating effects of NYDBT was observed based on the changes of body and hematopoietic organ (spleen, liver and femur) weights, red blood cell (RBC) related hematological values, smear cytology, histopathological changes and immunohistochemistrical analysis of hematopoietic stem cells in the femur bone marrow, liver and spleen. In addition, the gastrointestinal motility and the surface mucosa thicknesses of remnant fecal pellets in the colon lumen, mucosa thicknesses and the mucous producing cell numbers in the colonic mucosa were analyzed to observe the digestive disorders, especially on the constipation, the major discomfort problems in iron supplement. Results: SHA related abnormal anemic signs were markedly and dose-dependently inhibited by oral administration of NYDBT 500, 250 and 125 mg/kg in a condition of this experiment. In addition, no meaningful changes on the gastrointestinal motilities and mucous component on the colon and remnant feces were noticed in all three different dosages of NYDBT treated rats as compared with intact vehicle and SHA control rats in this study. Conclusions: It, therefore, is expected that NYDBT will be promising as a novel alternative hematopoietic and therapeutic agent for anemia.
