OBJECTIVETo analyze the effects to iron status who were given preventive iron supplements for two months from when they were breast-fed to four-month-old.
METHODSA total of 123 infants in four-month-old age who were breast-fed were randomly divided into iron supplementation group (63 cases) and control group (60 cases), iron supplementation group was supplied with low-dose iron (1 mg×kg⁻¹×d⁻¹) for two months with no intervention for control group. Blood samples were collected to test C reactive protein and iron status indicators in six-month-old age group infants, and the growth indices were measured and compared on the gender difference of iron status at and 6 months.
RESULTSAfter 2 months of low-dose iron supplementation, the hemoglobin of iron supplementation group (26 cases) increased about 5.5 g/L while the control group (34 cases) increases about 0.0 g/L (median), 95% confidence intervals were -7.0 - 13.0 g/L and -9.0 - 15.0 g/L, respectively. The hemoglobin increase of iron supplementation group was higher than the control group, the difference was statistically significant (u = -2.326, P < 0.05). The other iron nutritional status and the growth did not show any significant difference between iron supplementation group and control group (P > 0.05). At age 6 month, the MCV of the boys were (75.89 ± 3.34) fl, while the girls were (77.20 ± 3.17) fl. The boys had lower values of MCV than the girls, and the gender difference was statistically significant (t = 4.73, P < 0.05). The other iron nutritional status did not show any significant gender difference (P > 0.05).
CONCLUSIONLow-dose iron supplementation of breast-fed infants at 4-month-old can increase the hemoglobin level when they were 6-month-old, and had no measurable side effect on growth.

OBJECTIVETo understand iron nutritional status in school-age children, incidence of the sub-clinical iron deficiency (SID) and effect of iron supplementation on SID in the rural school-age children from mountainous areas of Beijing.
METHODSThe dietary survey and food frequency questionnaire survey were conducted in 1,012 school children aged 7 - 13 at rural mountainous areas of Fangshan District, Beijing, and their blood samples were collected for analyzing biochemical indicators for iron nutrition. Two hundred and sixty-seven children with IDs (iron deficiency store) and IDE (iron deficiency erythropoiesis), based on screening criteria for iron-deficiency anemia, received an iron supplementation (NaFeEDTA) capsule (containing 60 mg iron element) weekly, and those with IDA (iron deficiency anemia) received NaFeEDTA capsule thrice weekly for nine weeks. Blood biochemical indicators for iron nutrition were determined repeatedly and compared with those before and after the intervention.
RESULTSThe daily average intakes of energy, protein, iron and vitamin C in school children of all age groups reached the daily recommended criteria (> 85% of the RNIs), but the proportion of heme in dietary iron constitution was lower. The average blood biochemical indicators for iron nutrition were as follows: serum ferritin (SF) (50.83 +/- 33.09) micro g/L, free erythrocyte protoporphyrin (FEP) (489.44 +/- 219.61) micro g/L, hemoglobin (Hb) (130.57 +/- 10.82) g/L, and the ratio of FEP/Hb (3.83 +/- 1.96), respectively. Incidence of total iron deficiency in rural children was 26.5%, with proportions of iron deficiency (IDs), iron deficiency erythropoiesis (IDE), and iron deficiency anemia (IDA) of 15.5%, 7.1%, and 3.9% respectively. SID accounted for 85.4% of the total iron deficiency, which was 5.8 times as much as IDA. With iron supplementation for 9 weeks, the hematdogical index of iron increased significantly and returned to the normal level.
CONCLUSIONSThe incidence of subclinical iron deficiency in the rural school-age children was insidious and should be attached more importance, which was helpful to its early recognition and intervention. Iron supplementation is important for children with SID to prevent and decrease the occurrence of IDA.

6.Effects of iron supplementation on human serum level of transferrin receptor.
Chinese Journal of Preventive Medicine 2004;38(5):324-327
OBJECTIVETo study trend of dynamic change in level of serum transferrin receptor (sTfR) in the process of iron supplementation to provide evidence for sTfR in evaluating the efficacy of iron supplementation.
METHODSTotally, 942 child-bearing-age women aged 18 to 45 years were selected from Longfang City, Hebei Province and Shunyi County, Beijing. Biochemical indicators of iron metabolism were measured for all of them, including serum levels of ferritin (SF) and zinc protoporphyrin (ZPP), and hemoglobin (Hb). According to the current criteria for assessing iron status, women were screened for iron deficiency erythropoiesis (IDE) or iron deficiency anemia (IDA). Seventy-two women agreed to participate in the study, and 59 of them finished whole dynamic observations with signed informed consent. Four capsules of ferrous L-threonate (containing 7 mg of iron element per capsule) were administered for women with IDE every other day and for women with IDA every day, respectively, for 12 weeks. Serum biochemical indicators and level of sTfR were measured in 0 wk, 3 wk, 6 wk, 9 wk and 12 wk, respectively, during the process of iron supplementation, and their dynamic changes were observed.
RESULTSLevel of sTfR in women with IDE and IDA was (26.62 +/- 10.57) nmol/L and (41.25 +/- 21.96) nmol/L, respectively, significantly higher than normal level. During the process of iron supplementation, level of sTfR changed as the following characteristics. In women with IDE, level of sTfR kept stable within the first 3 weeks of iron supplementation, then dropped gradually and progressively, reached to normal, with (17.86 +/- 5.57) nmol/L, in the 12 wk after iron supplementation. In women with IDA, level of sTfR dropped quickly within the first 3 wk of iron supplementation, then dropped slowly until the 9th wk and kept stable, and reached to normal level in the 12 wk, with (19.54 +/- 5.94) nmol/L and a ratio of sTfR/SF of 12.23 +/- 4.34. Ratio of sTfR/SF changed as level of sTfR during the process of iron supplementation. Level of sTfR correlated reversely with levels of Hb and SF and positively with level of ZPP.
CONCLUSIONSerum level of sTfR in child-bearing age women gradually decreased to normal with the restoration of their normal iron status during the process of iron supplementation and could be used as a specific indicator for assessing efficacy of iron supplementation.

Klippel - Trenaunay syndrome (KTS) is characterized by a cutaneous vascular nevus of the involved extremity, bone and soft tissue hypertrophy of the extremity and venous malformations. We present a case of KTS with splenic hemangiomas and rectal varices. A 29-year-old woman was referred for intermittent hematochezia for several years. She had history with a number of operations for cutaneous and soft tissue hamangiomas since the age of one year old and for increased circumference of her left thigh during the last few months. Abdominal CT revealed multiple hemangiomas in the spleen, fusiform aneurysmal dilatation of the deep veins and soft tissue hemangiomas. There was no evidence of hepatosplenomegaly or liver cirrhosis. Colonoscopy revealed hemangiomatous involvement in the rectum. There were rectal varices without evidence of active bleeding. Upon venography of the left leg, we also found infiltrative dilated superficial veins in the subcutaneous tissue and aneurysmal dilatation of the deep veins. The patient was finally diagnosed with KTS, and treated with oral iron supplementation only, which has been tolerable to date. Intervention or surgery is not required. When gastrointestinal varices or hemangiomatous mucosal changes are detected in a young patient without definite underlying cause, KTS should be considered.

Role of iron in hair loss is not clear yet. The purpose of this study was to evaluate the relationship between iron and hair loss. Retrospective chart review was conducted on patients with female pattern hair loss (FPHL) and male pattern hair loss (MPHL). All patients underwent screening including serum ferritin, iron, and total iron binding capacity (TIBC), CBC, ESR and thyroid function test. For normal healthy controls, age-sex matched subjects who had visited the hospital for a check-up with no serious disease were selected. A total 210 patients with FPHL (n = 113) and MPHL (n = 97) with 210 healthy controls were analyzed. Serum ferritin concentration (FC) was lower in patients with FPHL (49.27 +/- 55.8 microg/L), compared with normal healthy women (77.89 +/- 48.32 microg/L) (P < 0.001). Premenopausal FPHL patients turned out to show much lower serum ferritin than age/sex-matched controls (P < 0.001). Among MPHL patients, 22.7% of them showed serum FC lower than 70 microg/L, while no one had serum FC lower 70 microg/L in healthy age matched males. These results suggest that iron may play a certain role especially in premenopausal FPHL. The initial screening of iron status could be of help for hair loss patients.

BACKGROUND/AIMS: Anemia in patients with inflammatory bowel disease significantly affects the quality of life. The aim of this study was to investigate the frequency of and risk factors for anemia and to describe the management of anemia in patients with intestinal Behcet's disease (BD) in actual clinical practice. METHODS: We included 64 patients with intestinal BD who visited the outpatient clinic of a tertiary referral center in June 2011 and had available laboratory data for the subsequent 6 months. RESULTS: Anemia was detected in 26 patients (40.6%). After 6 months, anemia was still present in 14 of these patients (53.8%). The cause of anemia was investigated in eight patients (30.8%), and oral iron supplementation was prescribed to four patients (15.4%). Of these four patients, two (50%) recovered completely within 6 months. Anemia was associated with a high Disease Activity Index for Intestinal Behcet's Disease (DAIBD, p=0.024), erythrocyte sedimentation rate (p=0.003), and C-reactive protein (p=0.049) in univariate analysis. In multivariate analysis, the factor predictive for anemia in patients with intestinal BD was a higher DAIBD (> or =40; odds ratio, 4.08; 95% confidence interval, 1.21 to 13.71; p=0.023). CONCLUSIONS: Although anemia is common in intestinal BD patients, its clinical importance is overlooked in daily practice. Moderate to severe disease activity is predictive of anemia.
