  • Lots of cases relating Helicobacter pylori infection to iron-deficiency anemia have been described in the literature and H. pylori infection has emerged as a cause of refractory iron-deficiency anemia which is unresponsive to oral iron therapy. H. pylori-associated iron-deficiency anemia can be treated by H. pylori eradication. It is not thought to be attributable to gastrointestinal blood loss, such as duodenal ulcer. The mechanism by which H. pylori infection contributes to iron-deficiency anemia remains unclear. However, four possible explanations can be posited for this relationship; occult blood loss secondary to chronic gastritis, reduced iron absorption due to hypo- or achlorhydria, increased iron consumption by H. pylori, and iron sequestration in gastric mucosa. H. pylori-associated iron-deficiency anemia seems to develop in populations at increased risk for iron depletion. When pubescent girls, including athletes, are found to have iron-deficiency anemia refractory to iron administration, they should be evaluated for H. pylori infection.

  • Anemia, defined as a reduction in the hemoglobin concentration of blood, is common in diabetes mellitus (DM) patients, can be potentially caused by diabetes complications such as nephropathy. Recent research suggests that diabetes mellitus (DM) itself may be a major risk factor of anemia. However, there are few Korean studies on the relationship between diabetes mellitus (DM) and anemia. This study was performed to investigate the association between anemia and diabetes mellitus (DM) in Korean adults. A total of 10,151 Korean adults over aged 19 years (4,422 male, 5,729 female) were selected from the participants of the Korean National Health and Nutrition Examination Survey VI (KNHANES VI). Korean adults with anemia had a higher prevalence of diabetes mellitus (DM) than the normal adults (11.4% vs. 30.4% in male, 8.8% vs. 9.4% in female). The unadjusted odds ratio (OR) for anemia was greater in adults with DM than in normal male (OR=3.28; 95% CI: 2.27~4.73). After adjusting for other risk factors including age, education, family income, smoking, drinking, and menstrual status, anemia and diabetes were not associated (OR=1.33; 95% CI: 0.84~2.09). Similarly, there was no association between anemia and diabetes in female. In conclusion, this study shows that the prevalence of anemia is similar in diabetic and non-diabetic Korean adults after adjusting for multiple risk factors. Further research is required to elucidate the mechanism of anemia caused as a consequence of diabetes mellitus (DM).

  • Background: Anemia is an important health problem affecting approximately 25% of the global population. Although its prevalence is decreasing worldwide, few studies have examined the prevalence of anemia in Korean adolescents. Purpose: This study aimed to determine the prevalence of anemia in Korean adolescents over the past 21 years using data from the Korea National Health and Nutrition Examination Survey. Methods: We investigated the prevalence of anemia in adolescents aged 10-18 years for the period 1998-2018 according to sex, age, residential area, and household income. The effects of menarche age and menstruation were examined in female adolescents for the period 2001-2018. Results: Among the total 11,782 participants, the weighted prevalence of anemia was 4.0%. The prevalence of anemia in male participants significantly decreased (from 3.0% to 0.5%, P<0.001), whereas that in female participants did not change significantly over time (from 7.9% to 8.5%, P=0.054). The average age at menarche was 12.4±0.0 years; the prevalence of anemia in females increased from age 13 years onward. Multivariate analysis revealed that anemia was more common in female than male participants (odds ratio [OR], 9.88; 95% confidence interval [CI], 7.19-13.57; P<0.001). In female adolescents, the prevalence of anemia increased with age (OR, 1.26; 95% CI, 1.15-1.38, P<0.001) and was 3.6 times higher after than before menarche (OR, 3.65; 95% CI, 2.21-6.05, P<0.001). Conclusion: Over the 21-year study period, the prevalence of anemia decreased among male adolescents but did not change in female adolescents. In female adolescents, age and menarche were identified as significant risk factors that require continued attention.

  • Background: Inflammatory diseases can increase the prevalence of anemia. Recent studies confirmed that the prevalence of anemia is increased by atopic dermatitis (AD), a chronic inflammatory disease. Therefore, we aimed to elucidate the correlation between AD severity and prevalence of anemia. Methods: We used data of pediatric patients from the Health Insurance Review and Assessment Service (HIRA-PPS-2016). We included pediatric patients (<18 years) with AD diagnosis who were prescribed medications for AD. We applied a propensity score method with inverse probability of treatment weighting (IPTW) adjusting for differences in prevalence of confounders and performed IPTW logistic regression to evaluate associations between the anemia and severity of AD. Results: In total, 91,501 patients (mild AD: 47,054 patients; moderate-to-severe AD: 44,447 patients) <18 years who were prescribed drugs for AD were analyzed. Analysis of the probability of patients with mild AD and prevalence of anemia as a reference revealed an odds ratio (OR) of 1.159 (95% CI, 1.109-1.212; p<0.001) in moderate-to-severe AD patients, indicating a correlation between anemia prevalence and AD severity. Subgroup analysis according to gender, age group, and type of health insurance revealed there was an association between AD severity and anemia except in patients equal or older than 7 years. Conclusion: The prevalence of anemia increased with AD severity despite adjusting for confounding factors. Our results support the hypothesis that AD can cause anemia, and anemia prevalence could be increased in severe AD patients. Further studies are needed to establish a pathological basis.

  • The purpose of this study was to compare the nutrient intake of elderly according to their cohabitation status and determine its effects on the prevalence of anemia. Data from the KNHANES were used for this study, including raw data on socioeconomic characteristics, nutrient intake, health status, and clinical laboratory findings. Study subjects aged 60 to 80 years were retrieved and analyzed. As a result, the prevalence of anemia was 12.0% (men, 11.6%; women, 12.3%). The prevalence rate increased with age, and odds ratio [OR] of anemia among those aged 75 to 80 years was 4.16 times higher in men (OR=4.16, 95% confidence interval [CI]=2.48-6.97) and 2.77 times higher in women (OR=2.77, 95% CI=1.86-4.14) compared to 60~64 years old. Socioeconomic factors (area of residence, education level, household income), including cohabitation Status (living alone VS living with other family members), and health behaviors (high-risk drinking, smoking, aerobic exercise) did not significantly effect on anemia. In addition, other than protein intake for men, nutrient intake did not have a significant effect on the prevalence rate of anemia. Hypertension, diabetes, and cancer significantly increased the risk of anemia. In Korea, the influencing factors of elderly anemia change over time, so periodic follow-up studies are needed.

  • Chronic kidney disease (CKD) causes numerous changes that destabilize homeostasis, of which anemia is one of its important complications. Anemia significantly reduces the quality of life in children with CKD and plays a crucial role in the progression of cardiovascular disease such as left ventricular hypertrophy, a major cause of mortality in those with advanced CKD. The treatment of anemia is a pivotal factor in reducing morbidity and mortality rates in children with CKD, representing one of the methods for enhancing patients' quality of life.

  • Background: Anemia is the most common hematologic abnormality in bladder cancer (BC) patients. We evaluated the impact of preoperative anemia on oncologic outcomes in BC undergoing transurethral resection of a bladder tumor (TURBT) for the first time diagnosis. Materials and Methods: We retrospectively evaluated the data collected from 639 patients who underwent TURBT between January 2006 and September 2014 in our department. Of these patients, 320 qualified for inclusion in the study. The primary efficacy endpoint was the effect of preoperative anemia status on cancer-specific and overall survival. Independent t-test and chi-square analyses were performed to assess the effects of anemia on oncologic outcomes. Survival was estimated by using the Kaplan-Meier test. Results: There were 118 (36.9%) and 202 (63.1%) patients in the anemia (Group-1) and non-anemia groups (Group-2), respectively. The median follow-up duration was 68 months. Anemia was associated with decreased overall survival (p<0.001). Comparison between cancer-specific survival of two groups did not show any statistically significant difference (p=0.17). Conclusions: Preoperative anemia status of BC patients according to World Health Organization classification is associated with decreased overall survival, but not with cancer-specific survival. We think that preoperative hemoglobin levels should be considered in patient counseling and decision-making for additional therapy.

  • The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseass were studied by various methods. Only patients without previous blood loss were included: 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and $T_{50}Cr$. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.
