Iron deficiency associates with deterioration in several symptoms independently from hemoglobin level among chronic hemodialysis patients.

ABSTRACT:

Background

While iron deficiency (ID) is a frequent cause of anemia in hemodialysis patients, the clinical impact of ID without anemic level of hemoglobin remains unclear. As such, this study was designed to clarify the manifestations of ID itself in subjects on hemodialysis.

Methods

Maintenance hemodialysis patients achieving target hemoglobin levels (? 10.0g/dL) under treatment in our clinic were stratified for comparison from three perspectives: ID (transferrin saturation [TSAT] < 20% or ferritin < 100ng/mL) vs non-ID, level of TSAT (< or ? 20%), and level of serum ferritin concentration (< or ? 100ng/mL). The severity of frequent symptoms was determined by a self-rating symptom score questionnaire, and the rate of those with severe manifestations was calculated for each symptom. Significant difference was examined between groups; univariate and adjusted multivariate odds ratios and 95% confidence intervals were obtained by logistic regression.

Results

Among 154 subjects selected for analysis, the ratio of severe arthralgia and fatigue was significantly higher in the ID group (n = 94) compared to the non-ID group (n = 60), in both univariate and adjusted multivariate analyses. Moreover, in multivariate analysis, low TSAT was significantly associated with exacerbation of pain during vascular access puncture and intradialytic leg cramps, while low serum ferritin concentration was related to significant increase in severe arthralgia, fatigue, intradialytic headache and leg cramps.

Conclusions

ID was identified as a risk factor regarding severity of several symptoms even without low hemoglobin level among chronic hemodialysis patients, and supplementation of iron was considered efficacious for improving critical symptoms affecting those undergoing maintenance dialysis.

Project description:The prevalence of iron deficiency anemia is highest among low and middle-income countries. Millets, including sorghum, are a traditional staple in many of these countries and are known to be rich in iron. However, a wide variation in the iron composition of millets has been reported, which needs to be understood in consonance with its bioavailability and roles in reducing anemia. This systematic review and meta-analysis were carried out to analyze the scientific evidence on the bioavailability of iron in different types of millets, processing, and the impact of millet-based food on iron status and anemia. The results indicated that iron levels in the millets used to study iron bioavailability (both in vivo and in vitro) and efficacy varied with the type and variety from 2 mg/100 g to 8 mg/100 g. However, not all the efficacy studies indicated the iron levels in the millets. There were 30 research studies, including 22 human interventions and 8 in vitro studies, included in the meta-analysis which all discussed various outcomes such as hemoglobin level, serum ferritin level, and absorbed iron. The studies included finger millet, pearl millet, teff and sorghum, or a mixture of millets. The results of 19 studies conducted on anaemic individuals showed that there was a significant (p < 0.01) increase in hemoglobin levels by 13.2% following regular consumption (21 days to 4.5 years) of millets either as a meal or drink compared with regular diets where there was only 2.7% increase. Seven studies on adolescents showed increases in hemoglobin levels from 10.8 ± 1.4 (moderate anemia) to 12.2 ± 1.5 g/dl (normal). Two studies conducted on humans demonstrated that consumption of a pearl millet-based meal significantly increased the bioavailable iron (p < 0.01), with the percentage of bioavailability being 7.5 ± 1.6, and provided bioavailable iron of 1 ± 0.4 mg. Four studies conducted on humans showed significant increases in ferritin level (p < 0.05) up to 54.7%. Eight in-vitro studies showed that traditional processing methods such as fermentation and germination can improve bioavailable iron significantly (p < 0.01) by 3.4 and 2.2 times and contributed to 143 and 95% of the physiological requirement of women, respectively. Overall, this study showed that millets can reduce iron deficiency anemia.

Project description:BackgroundKlotho is a kidney-derived protein that is involved in various kidney diseases. The role of serum soluble Klotho (sKlotho) in the anemia of patients undergoing hemodialysis has not been well characterized.ObjectiveWe aimed to characterize the relationship between sKlotho and hemoglobin (Hb) levels in this group of patients.DesignA single-center cross-sectional study of 208 patients undergoing maintenance hemodialysis (MHD) and 50 healthy controls was performed between June 1 and 31, 2023.MethodsDemographic information and biomedical parameters, such as age, body mass index, medication use, and their Hb, albumin, interleukin-6, and sKlotho concentrations, were obtained. Patients undergoing MHD were allocated to a group that achieved the Hb target (⩾110 g/L) and a group that did not (<110 g/L). Correlation analysis and multivariate logistic and linear regression analyses were performed to evaluate the relationship of sKlotho with Hb concentration.ResultsParticipants undergoing MHD had lower Hb and sKlotho concentrations than controls. Those who had not achieved the target Hb level were given fewer erythropoiesis-stimulating agents and had lower sKlotho and albumin concentrations, but higher interleukin-6 concentrations, than those who had achieved the Hb target. The sKlotho concentration positively correlated with the Hb concentration and was inversely associated with the incidence of a lack of achievement of the target Hb level. Multivariate logistic regression models revealed that there was a close association between sKlotho and a lack of achievement of the target Hb level after adjustment for potential confounders (odds ratio: 0.335, 95% confidence interval: 0.142-0.791, p = 0.013). This relationship was closer on multivariate linear regression analysis when sKlotho was included as a continuous variable.ConclusionThe circulating sKlotho concentration is very low, but deficiency of this protein is independently associated with a high risk of anemia in patients undergoing MHD. Therefore, the routine monitoring of sKlotho concentration might be useful in the management of renal anemia in such patients.
