Cancer is a group of diseases in which cells are aggressive, invasive and sometimes metastatic. Nutritional status an important factor that contributes to immune competence for which trace minerals plays a crucial role in the biochemical and physiological activity of the system. Trace element a category of minerals essential for the biological system and plays an active role in immune effector mechanism.  Normal range of iron essential for body metabolism, iron deficiencies leads to anemia which might complicate the event of tumor genesis. Study involved 50 volunteers (36 females, 14 males) of cancer patients of Mohan Nursing Home Madurai. Serum was collected in the informed consent of the patients. Serum iron level was quantified using Atomic Absorption Spectrophotometer. Study documented percentage deviation of serum iron concentration (85%) with severe anemic prevalence from the control individual (without cancer) and also establish an association of iron deficiency with anemic prevalence. Study documented the existence of Iron deficiency which is the most common cause of anemia worldwide. Iron plays a role in oxygen transfer in cytochromes, protein molecules involved in the production of energy in cells and also exhibit certain properties to facilitate antitumor status. Study concludes that serum iron modulations need to be emphasized to minimize the burdenization of the host with Clinical associated complications of Iron deficiency among patients with cancer.

Background An increasing number of studies have shown that iron, one of the indispensable trace elements in the human body, is closely related to the occurrence and development of cancer. However, few studies have clearly demonstrated the role of the iron levels in lung cancer patients, or the potential effects of inflammation on iron levels. Methods The clinical data for lung cancer patients and non-lung cancer participants were retrospectively analyzed. The serum iron and ferritin levels were measured and compared using a rank-sum test. The correlation between the serum iron/ferritin and C-reactive protein (CRP) was analyzed by rank correlation. The cut-off values for continuous variables were obtained by the receiver operating characteristic curve (ROC) method. An analysis of potential prognostic factors in lung cancer patients was conducted by univariate and multivariate survival analyses. Results The serum iron levels in patients with extensive small-cell lung cancer (SCLC) were lower than those with limited-stage SCLC, and the levels of serum ferritin and CRP in those with extensive SCLC were higher than those with limited-stage SCLC. Similarly, the serum iron levels in patients with stage IV non-small cell lung cancer (NSCLC) were lower than those of patients with stage Ⅰ-Ⅲ disease, and the levels of serum ferritin and CRP in those with stage IV NSCLC were higher than those in stages Ⅰ-Ⅲ. The serum iron level was negatively correlated with the level of CRP, while the serum ferritin level was positively correlated with CRP. The stage of lung cancer, but not the serum iron/ ferritin level, was an independent prognostic factor in lung cancer patients. Conclusions The serum iron and ferritin levels are associated with the staging of lung cancer. The later stages of lung cancer are associated with a lower serum iron level, a higher serum ferritin level, and a higher CRP level. Inflammation may play an important role in regulating the serum iron and ferritin levels in lung cancer patients.

Pyridoxine Deficiency

Abstract Rats fed a diet deficient in pyridoxine all exhibited a severe microcytic hypochromic anemia after 40 to 50 weeks. This anemia responded promptly to pyridoxine administration. The myeloid:erythroid ratio in the bone marrow of the severely anemic rats was definitely increased, suggestive of hypoplasia of the erythroid series, after prolonged deprivation of pyridoxine. The ratio was markedly decreased shortly after the inception of pyridoxine treatment, indicating active erythropoiesis induced by therapy; the ratio subsequently returned toward normal when hemoglobin level improved. There was no evidence of accumulation of iron in the bone marrow. The serum iron level increased only slightly, to high-normal values in the anemic rats, but fell to low-normal level after the administration of pyridoxine.

Abstract Background Various types of pulmonary diseases are associated with iron deficiency. However, information on iron status in coronavirus disease 2019 (COVID-19) is scarce. Methods This study included 50 hospitalized patients with confirmed COVID-19. The role of serum iron in predicting severity and mortality of COVID-19 was evaluated. Results The most common symptoms of COVID-19 patients in this study were cough (82%), fever (64%), and chest distress (42%). Of the 50 patients, 45 (90%) patients had abnormally low serum iron levels (<7.8 μmol/L). The severity of COVID-19 was negatively correlated with serum iron levels before and after treatment and was positively correlated with C-reactive protein, serum amyloid A, D-dimer, lactate dehydrogenase, urea nitrogen, and myoglobin levels. Decreased serum iron level could predict the transition of COVID-19 from mild to severe and critical illness. Seven (53.8%) patients with a lower serum iron level after treatment in the critical group had died. There was a significant difference in posttreatment serum iron levels between COVID-19 survivors and nonsurvivors. Conclusions Serum iron deficiency was detected in the patients with COVID-19. The severity and mortality of the disease was closely correlated with serum iron levels. Low serum iron concentration was an independent risk factor for death in COVID-19 patients.

Different Types

Objectives: Malnutrition is a common condition among children and iron status varies in different types of malnutrition. So the present study is aimed to find the different iron status among severe malnourished children in our context. Methods: A hospital based cross sectional study was done in the Paediatrics ward Chittagong Medical College Hospital in a period of 6 months from January to July 2013 among the 50 cases of malnourished children of age range between 1 to 5 years and Weight for Height Z score(WHZ) was <-2  SD. Sampling technique was continuous purposive sampling. Venous blood was collected to assay the different iron profile mainly serum iron level, total iron binding capacity(TIBC) and transferrin saturation(TSAT). Data was analyzed after correction by SPSS-19. Results: Among the 50 study children of different age groups 15 patients were 1 to 2 years, 18 patients were 2 to 3 years, 10 patients were 3 to 4 years and 7 patients were at 4-5 years of age groups. Among the patients, 29 (58%) of patients were female and 21(42%) of the patients were male. Most of the children were from the families of low socioeconomic status 38(76%). 2(4%) children were from upper middle class who had step mother. Among the selected patients the dominating clinical features were anemia was found among 45(90%) of patients which was mild(66.6%), moderate(26.6%) and severe(6.6%). Skin changes(32%), eye  changes (10%) and hair changes(48%) were also found. Among the 50 study subjects prelacteal feeding was given among 43(86%) children, breast feeding was given 45(90%), exclusive breast feeding was given to 24(48%) of children and complementary feeding after 6 months was given to 29(58%) patients. Among the 50 patients -2 to -3 SD weight for height was found in 20(40%) patients and <-3 SD was found in 30(60%) patients. Most of the children was found to have Mid Upper Arm Circumference (MUAC) 115-125 mm(50%). Iron status was measured among all patients where serum iron level was found 77.72 ± 11.22 mcgm/dl, TIBC was found 340.07 ± 22.67 mcgm/dl and transferrin saturation was found 22.38 ± 2.9 %. Iron status were measured among the different types of malnutrition where serum iron level and transferrin saturation was high among all patients with malnutrition while TIBC was lower than standard level in all patients. Different biochemical status were measured among the different types of malnutrition where serum total protein, serum albumin, Hb% were lower than standard level in all patients.Conclusion: Change in different iron status is a common findings in malnourished children. Screening of all children for anemia and providing iron and folic acid (IFA) or multiple micronutrients (MMN) supplements to children and Infant and Young Child Feeding (IYCF) should be addressed at all level to overcome the situation.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i3.21024

Hepcidin is an important hormone regulating the systemic iron bio-availability. Blood samples were collected from thirty pregnant cattle during their last trimester of pregnancy to assess the relation of hepcidin to iron homeostasis. Serum hepcidin level was quantified using ELISA and serum iron, transferrin iron binding capacity and unsaturated iron binding capacity were estimated by colorimetric method. Correlation between hepcidin and other iron related parameters was assessed. Dependency of serum iron level on hepcidin was also determined by regression method. It was revealed that hepcidin was negatively correlated to serum iron and transferrin iron binding capacity (p less than 0.001) and also hepcidin has highest predictive value on serum iron level and transferrin iron binding capacity (p less than 0.001). It can be concluded that during pregnancy increase in hepcidin reduces the maternal serum iron and also it is a biomarker for iron bioavailability to the developing fetus.

Iron Profile

723 Background: ICIs have improved survival in mRCC patients (pts), yet response rates (RR) to these treatments are variable. Biomarkers predictive of response to ICIs may improve outcomes for mccRCC pts. Genes that promote tumor-specific iron accumulation such as hepcidin (HAMP) or transferrin (TF) are significantly correlated with decreased overall survival in clear cell RCC (TCGA-KIRC). Iron deficiency in cancer patients is positively correlated with tumor stage and inversely proportional to treatment response (PMID: 23567147). Here, we investigate whether serum iron profile may be associated with response to ICIs in mccRCC pts. Methods: Clinical data was obtained from an mRCC registry at the Huntsman Cancer Institute, University of Utah. Analyses were limited to mccRCC pts who had serum iron studies within 6 months before initiating an ICI and had been assessed for RR. ICIs included nivolumab + ipilimumab, atezolizumab, or nivolumab alone. Responses were defined as complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD) by RECIST criteria. Clinical benefit (CB) was defined as CR + PR + SD. Descriptive statistics were used to assess associations between iron stores and response to ICIs and IMDC criteria. Results: 36 pts met all aforementioned eligibility criteria (29 were of IMDC intermediate risk, 7 were of IMDC poor risk). 5 pts received a first-line ICI, and the remaining 31 pts received ICIs as salvage therapy. Pts with CB had a significantly higher median serum iron level compared to those with no CB (59 vs 38.5 ug/dL; p=0.024). Furthermore, pts with normal transferrin saturation (TSAT %) were more likely to derive CB from ICIs (p=0.048). No association was found between serum ferritin (a marker of inflammation and tissue iron) and response to ICIs. Conclusions: In this hypothesis-generating study, increased serum iron, and TSAT levels within the normal range are associated with an increased likelihood of response to ICIs in pts with mccRCC. Once validated, these results may establish serum iron profile as a predictive marker of response to ICIs, in addition to providing the rationale for ruling out iron deficiency before starting ICIs.
