Iron deficiency in nonanaemic COPD patients-Could Low haemoglobin density and Microcytic anaemia factor be usefull?

Erythrocyte indices LHD and Maf are complementary parameters to complete blood count and have been shown as reliable iron deficiency markers in different clinical settings. The aim of the study was to assess diagnostic performances of LHD and Maf in detecting iron deficiency in nonanaemic stable COPD patients. A total of 93 nonanaemic stable COPD patients were classified as either iron deficient (ID, N=15) or non-iron deficient (non-ID, N=78). Iron deficiency was defined as a ferritin level < 100 μg/L with a transferrin saturation (TSAT) <20%. A complete blood count, including LHD and Maf as well as other relevant inflammation and iron status parameters were obtained for all participants. Both LHD and Maf have shown significant differences between the ID and non-ID group with p=.003 and p=.007 respectively. The AUC for LHD was .744 (95% CI: .626-.863, p=.003) with the best cut-off of 5.85 and sensitivity of 80% (95% CI: 76.0-84.0) and specificity of 61.5% (95% CI: 58.4-64.6). The AUC for Maf was .707 with optimal cut-off value 12.65 and sensitivity of 83.3% (95% CI: 79.1-87.5) and specificity of 60.0% (95% CI: 57.0-63.0). Furthermore, LHD performance was not affected by vitamin B12 status. LHD and Maf are useful for iron deficiency diagnosis in stable COPD patients. LHD was shown to be resistant to vitamin B12 deficiency, which is of substantial importance in specific patient subpopulations. Both parameters are not technology-dependant and do not require additional sample and/or reagent volume, which makes them cost-effective and convenient for everyday use.

Erythrocyte Indices in Patients With Takotsubo Syndrome.

Although the prognosis of patients with Takotsubo syndrome (TTS) is relatively favorable, serious complications may occur. This study aimed to investigate the relationship between blood parameters and the occurrence of in-hospital complications. Clinical charts of 51 patients with TTS were retrospectively evaluated, and data regarding blood parameters assessed during the first 24 hours of hospitalization were studied. Levels of hemoglobin less than 13 g/dL in men and 12 g/dL in women (P < 0.01), levels of mean corpuscular hemoglobin concentration (MCHC) less than 33 g/dL (P = 0.01), and levels of red blood cell distribution width-coefficient of variation higher than 14.5% (P = 0.01) were significantly associated to the occurrence of major adverse cardiovascular events (MACE). Markers, such as, platelets to lymphocytes ratio, lymphocytes to monocytes ratio, neutrophils to lymphocytes ratio, and white blood cell count to mean platelet volume, were unable to differentiate patients with and without complications (P > 0.05). MCHC and estimated glomerular filtration rate were independent predictors of MACE. Blood parameters may have a role in the stratification risk of patients with TTS. Patients showing low levels of MCHC and decreased estimated glomerular filtration rate were more likely to have in-hospital MACE. This should encourage physicians to closely monitor blood parameters in patients with TTS.

Reference range of complete blood count, Ret-He, immature reticulocyte fraction, reticulocyte production index in healthy babies aged 1–4 months

Establishing reference ranges of the complete blood count (CBC), reticulocyte hemoglobin content (Ret-He), immature reticulocyte fraction (IRF), and reticulocyte production index (RPI) helps diagnose a disease related to the changes in erythrocyte indices, white blood count, platelets, and reticulocytes, especially in babies. Therefore, the study aims to establish a reference range for CBC and reticulocyte parameters in healthy babies aged 1–4 months. The study design was a cross-sectional study with descriptive analysis of CBC and reticulocyte in babies aged 1–4 months. Three hundred forty-eight babies met the inclusion criteria. This study recruited 89 babies aged 1 month, 87 babies aged 2 months, 86 babies aged 3 months, and 86 babies aged 4 months. The P5-P95 reference range of healthy babies for hemoglobin (Hb) aged 1 month, 2 months, 3 months, and 4 months was 9.95 to 15.45 g/dL, 9.74 to 13.42 g/dL, 9.51 to 12.40 g/dL, and 10.04 to 13.10 g/dL respectively. The P3-P97 reference range of healthy babies for Hb aged 1 month, 2 months, 3 months, and 4 months was 9.60 to 15.90 g/dL, 9.46 to 13.97 g/dL, 9.26 to 12.82 g/dL, and 10.00 to 13.33 g/dL respectively. This study also defined reference ranges for CBC, Ret-He, IRF, and RPI. The reference range of CBC, Ret-He, IRF, and RPI for healthy babies aged 1–4 months in this study can be used as a benchmark.

Effects of alginates on the growth, haematological, immunity, antioxidant and pro-inflammatory responses of rabbits under high temperature

Heat stress (HS) is one of the most severe hurdles impacting rabbit growth, immunity, homeostasis, and productivity. Alginate oligosaccharides (AOS) have considerable beneficial effects due to their plausible antioxidant and immune-stimulatory properties. This work was planned to explore the preventive function of AOS as a new bio-feed additive against the harmful effects caused by environmental HS on growing rabbits. Rabbits were allotted in four experimental groups (25 animals in each group) and fed on a basal diet supplemented with 0.0 (AOS0), 50 (AOS50), 100 (AOS100), and 150 (AOS150) mg AOS/kg diet reared under summer conditions. Dietary AOS supplementation improved significantly (P ≤ 0.001) feed conversion rate, while both AOS100 and AOS150 significantly (P ≤ 0.001) enhanced the final body weight and body weight gain. All AOS addition significantly increased nitric oxide and lysosome activity and significantly reduced interferon-gamma (IFNγ) compared with those in the control group. Tumor necrosis factor α (TNFα), interleukin1β (IL-1β), myeloperoxidase and protein carbonyl levels were significantly reduced in rabbits fed diets containing AOS (100 and 150 mg/kg) compared with those in the control group under heat stress conditions. In addition, glutathione (GSH) and catalase (CAT) were significantly (P ≤ 0.001) improved with increasing AOS dietary levels compared with the control group. Still, total antioxidant capacity (TAC), malondialdehyde (MDA), hematocrit, mean corpuscular volume (MCV), eosinophils, and lymphocytes did not change. Erythrocyte's indices improved significantly (P ≤ 0.001), while neutrophils and white blood cell counts were decreased by dietary AOS inclusion. Immunological (IgM and IgG) were markedly reduced in AOS-treated groups compared with the control group. The current investigation exemplified that AOS as a novel bio-feed additive that could be an effective strategy to extenuate prejudicial effects in heat-stressed rabbits via enhancing immunity, and antioxidant defence system, further regulating the inflammation cytokines.

Morphological and functional features of boar erythrocytes under environmental and technological stress and their effect on the leukocyte composition of the blood

Purpose: study the response possibilities of boar blood erythrocytes to the conditions of environmental and technological stress; to establish possible reference intervals for their morphological and functional parameters and to evaluate their effect on the leukocyte composition of the blood.Materials and methods. At the first stage, all the Poltava meat breed main boars of the breeding herd were examined. In accordance with the possibilities of providing the oxygen budget of the organism, the boars were divided into two groups according to the principle of analogue pairs. The control group (I) consisted of boars, in which the indicators of erythrocyte number and hemoglobin corresponded to the reference values indicated in the literature. The experimental group (II) consisted of animals that were not included in the control group. All animals belonged to the “elite” and “first” classes and were clinically healthy. Ecological and technological factors acted as stressors. The following was determined in the blood: the number of erythrocytes, hemoglobin, leukocytes, leukocyte blood picture (formula). Calculated: hemoglobin index (color index), hemoglobin content in 1 erythrocyte (pg) (MCH). To characterize the stage of stress, we used the integral hematological index of the ratio of lymphocytes and neutrophils – the leukocyte index. The results obtained were processed statistically.Results. The use of industrial production technology in the farm turned out to be stress-realizing for the boars of the main Poltava meat breed herd. Most of the examined boars of the herd (64.7±1.3 %) had, in these keeping conditions, in general, well-formed mechanisms for an adequate response of the adaptive potential, which manifested itself in maintaining the number of erythrocytes and hemoglobin in the blood at the level of literary reference intervals. Under conditions of environmental and technological stress, with a probability of 95 %, the reference interval established by us in terms of the number of erythrocytes in the blood of boars in the control group was 5.63-7.12 x1012 /l, in terms of the amount of hemoglobin in the blood - 100.54-115 .65 g/l. After the “selection of animals” according to the “physiological” indicators of erythrocytes and hemoglobin, the average values of erythrocyte indices in boars of the control group significantly decreased compared to the experimental group. In boars with a physiological level of provision of the oxygen budget of the body, the stress reaction took place without straining the functional capabilities of the body. A more stable, lower value of the volume index of neutrophils and lymphocytes variability level in the blood; a significantly higher, but not out of the literature reference intervals, content of monocytes and stab neutrophils in the blood was observed.Conclusion. The action of environmental and technological factors in boars undoubtedly leads to the development of a stress reaction and causes changes in the composition of the blood, both in the erythrocyte and leukocyte links. At the same time, the level and direction of adaptive reactions depend on the possibilities of providing the oxygen budget of the organism.

ВЛИЯНИЕ РОСТА СКЕЛЕТНО-МЫШЕЧНОЙ МАССЫ НА ПОКАЗАТЕЛИ ОБМЕНА ЖЕЛЕЗА У ВОЕННОСЛУЖАЩИХ ПО ПРИЗЫВУ В ПЕРИОД АДАПТАЦИИ К УСЛОВИЯМ ВОЕННОЙ СЛУЖБЫ

Thousands of young men are conscripted for military service with various nutritional status and physical fitness condition every year. The adaptation of conscripted soldiers to the factors of military service occurs at three levels: physiological, psychological and social. The purpose of the study was to assess the dynamic changes of body structure parameters in conscripted soldiers during 6 months of service by conscription and to determine the effect of skeletal muscle mass growth on iron metabolism during adaptation to military service conditions. A prospective observational study involved 145 conscripted soldiers from one of the military units after informed consent. The study was performed from the moment of conscription for military service in 3 stages with an interval of 3 months using a four-component model of body structure and a four-component model of iron metabolism. The skeletal muscle mass and adipose tissue mass and were determined caliperometrically. Hematological and biochemical parameters of iron metabolism were assessed. Dynamic changes and types of growth of the skeletal muscle mass, as well as changes in the parameters of iron metabolism have been obtained. The body weight of conscripted soldiers changes slightly within 6 months from the moment of conscription. At the same time internal changes occurred in the structure of the body of conscripted soldiers due to an increase in skeletal muscle mass and a decrease in the mass of adipose tissues. The types of skeletal muscle mass growth were determined among conscripted soldiers. There were an increase in skeletal muscle mass and hemoglobin fund to provide them oxygen by the influence of increased physical loading. It led to a decrease in iron stores, estimated by serum ferritin, and signs became more pronounced of iron deficiency erythropoiesis, which were determined in erythrocyte indexes. These combined changes can be assessed as functional iron deficiency or iron deficiency without anemia.

Restoration of hepatorenal dysfunction and injury by zinc and folic acid combination in bisphenol A-intoxicated mice

Bisphenol-A (BPA) is a potentially hazardous substance and is extensively used in manufacturing industries as a plasticizing agent. The current research intended to determine the revival actions of zinc (Zn) and folic acid (FA) on hematological parameters and hepatorenal function in BPA-exposed male albino mice. A total of 75 adult male mice, aged 25 to 28 days, were split into five groups. Group A (the control group) received a normal diet, while a daily dosage of 50 mg BPA/kg body weight (BW) in the diet was provided to groups B–E. Groups C, D, and E received daily supplements of 10 mg Zn/kg BW, 3 mg FA/kg BW, or both in the feed. After 12 weeks of treatment, serum was prepared by collecting blood, and the kidney and liver were taken for a histotexture study. The results demonstrate that hematological values dropped significantly (p&lt; 0.05) in the BPA-treated group and increased following Zn and FA supplementations, while no significant alterations in erythrocyte indices were observed among control and treated groups. The BPA group used to have significantly (p&lt; 0.05) higher liver and kidney biomarkers levels, which were restored by Zn and FA. The effects of BPA administration included severe hepatocyte degeneration and necrosis, as well as renal tubule epithelium loss, all of which were improved by Zn and FA. Hence, the findings suggest Zn and FA could be potential preventative agents against BPA-induced toxicity.

Haematology profile of dogs with primary uterine inertia

Primary uterine inertia is the inherent inability of the uterus to contract and expel a fully grown foetus after the end of the gestation period, through a normal birth canal, in the absence of obstructive dystocia.There are conflicting reports regarding the blood parameters in parturient animals,and animals with dystocia and its role in uterine inertia are not well documented. Haematology analysis was performed in dogs with Complete Primary Uterine Inertia (CPUI, n=9) and Partial Primary Uterine Inertia (PPUI, n=6), as well as control animals with the Foetal Cause of Dystocia (FCD, n=7).Blood samples were collected from the study population and total leucocyte count (TLC), total erythrocyte count (TEC), differential leucocyte count (DLC), erythrocytic indices, haemoglobin and haematocrit values were estimated in an autoanalyzer. Haematology analysis revealed no significant difference between the groups. Differential leucocyte counts exhibited lymphocytosis across the groups suggestive of the active immune response related to CL lysis,a characteristic associated with the termination of the pregnancy in canines. Erythrocyte count, haemoglobin concentration and haematocrit revealed anaemia across the group.The study characterised the haematology profile of prepartum canines, which indicated anaemia associated with haemodilution and lymphocytosis associated with active immune status. It also proved that the haematology profile doesnot have any significant role in the pathogenesis of canine uterine inertia.

Haematological and Biochemical Anomalies in Catfish, Clarias batrachus due to Cutaneous Ulcerations

The present study was carried out to investigate the haematological and biochemical parameters in healthy and ulcerated Catfish, Clarias batrachus. The haemorrhagic necrotic skin lesions in ulcerated fishes showed significant reduction (P&lt;0.01) in RBC, haemoglobin, haematocrit (PCV) eosinophils and lymphocytes. The derived erythrocyte indices, namely, the MCV, MCH and MCHC of ulcerated fishes were also significantly decreased (P &lt; 0.05) from those of normal fishes. Whereas, the total leucocyte count (TLC), neutrophils, monocytes and ESR were significantly increased (P&lt;0.01 and P&lt;0.05) in infected fishes. The biochemical analysis showed a significant reduction (P&lt;0.01) in bilirubin content, whereas the blood glucose, SGOT and SGPT were significantly increased (P&lt;0.01).

Assessment of haematological and histopathological effects of mixture toxicity of phenanthrene and benzo[a]pyrene in catfish

The effect of joint mixtures of phenanthrene and benzo[a]pyrene on selected haematological and histopathological parameters of the Clarias gariepinus was investigated. Healthy juvenile C. gariepinus (n = 90) weighing 19.7 ± 1.8 g were exposed to sublethal concentrations of joint mixtures of phenanthrene and benzo[a]pyrene for a subchronic period of 35 days. Acute toxicity studies showed that phenanthrene and benzo[a]pyrene had LC50 values of 1400 and 16 μg/L respectively while the safe limits of the chemicals varied in the ranges of 0.00016 to 1.6 μg/L and 0.014 to 140 μg/L for benzo[a]pyrene and phenanthrene respectively. The joint mixture significantly (p &lt; 0.05) reduced growth rate in exposed fish. The joint mixtures also led to significant (p &lt; 0.05) declines in the studied haematological parameters including blood cell count (RBC), haemoglobin (Hb) and haematocrit (Hct). The erythrocyte indices including mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) all showed significant (p &lt; 0.05) declines in the presence of the joint toxicants. There were significant (p &lt; 0.05) increases in white blood cells (WBC) count and platelet (PLT) count. Histopathological examination showed alterations in liver and gill sections of exposed fish

Uji Performa Pertumbuhan Dan Profil Sel Darah Merah Ayam Broiler (Fase Starter) Yang Diberi Pakan Tepung Magot Bsf (Black Soldier Fly) Sebagai Pakan Tambahan Pada Ransum Komersial

This study aims to determine the effect of adding Black Soldier Fly (BSF) maggot flour at several levels (dose) in complete feed on feed consumption, ration conversion, growth (body weight gain) and red blood cell profile in broiler chickens. The research material used 100 chickens. This study used a Completely Randomized Design (CRD) with 4 treatments where each treatment was filled with 25 animals/treatment. Parameters observed were ration consumption, body weight gain, feed conversion and broiler blood cell profile. The data obtained will be presented in the form of a table and described descriptively. The results showed that the addition of Black Soldier Fly (BSF) maggot flour had an effect on body weight gain but did not show a significant difference between the treatment groups. The addition of BSF maggot flour did not affect the red blood cell profile where the total erythrocyte, hemoglobin, hematocrit and erythrocyte index showed normal values. The conclusion in this study was that the addition of maggot flour to commercial rations affected the degree of feed palatability, thus affecting the level of consumption and erythrocyte profile at the beginning of rearing and the addition of protein in the finisher phase had no effect on feed efficiency.

Analysis of Examination Results of Erythrocyte Index in Pulmonary TB Patients Labuang Baji General Hospital, Makassar City

The high rate of transmission of tuberculosis (TB) in Makassar City is very concerning. Data from the Makassar Health Office (Dinkes) in 2019 there were 5,412 TB cases. The data then decreased during the pandemic to 3,260 cases in 2020. And 3,911 cases in 2021 with a recovery rate of 83% in 2019 and 85% in 2020. The purpose of this study was to determine the value of the erythrocyte index in patients with pulmonary tuberculosis at the Hospital of Labuang Baji, Makassar City. The type of research used is laboratory observation with descriptive method. The population in this study were all patients with pulmonary tuberculosis as many as 11 people with pulmonary tuberculosis. The results obtained are known for the MCV value, 8 tuberculosis patients have a normal MCV value, 2 patients have a low MCV value and one has a high MCV value, for the MCH value, 6 tuberculosis patients have a normal MCH value, 4 patients have a high MCH value. low and one patient had a high MCH value, for the MCHC value 4 people with tuberculosis had a normal MCHC value and 7 patients had a low MCHC value.

Molecular detection of Theileria spp. in native sheep and estimation of hemato-biochemical parameters from Sulaimani province/Iraq.

Theileriosis, the hemoprotozoan infection, is an endemic condition in tropical and subtropical areas. In this study, conventional PCR analysis was applied to detect the natural infection of native sheep with theileriosis and estimate its effect on hemato-biochemical parameters. The study was carried out in five regions of Sulaimani province, northern Iraq. From May to October 2021, a total of 360 blood samples were collected randomly from the jugular vein of sheep belonging to 23 flocks with a history of tick infestations. After PCR for theileriosis, the hematobiochemical parameters were evaluated by an automatic analyzer using commercial kits. The PCR results represented that 71.7% of the examined sheep were infected with Theileria parasites. The highest prevalence rate (74.6%) was reported in Said Sadiq, and the lowest prevalence (69.5%) was from Bazian. The infection rates in Mawat, Qaradagh, and Sharazoor were 73.1, 70.3, and 71.8%, respectively. The hemogram data revealed a significant decrease in erythrocyte count, hemoglobin concentration, and hematocrit values. Erythrocyte indices also showed significant increases in MC, MCH, and MCHC levels, but no significant differences were detected between the counting of leukocytes, lymphocytes, and granulocytes. Biochemical analysis revealed a significant decrease in total protein, albumin, and creatinine levels with a significant increase in urea and AST levels in infected sheep with theileriosis. Alteration in hemato-biochemical parameters from infected animals can outline the impact of theileriosis on body metabolism and blood factors in naturally infected sheep.

Effects of Exposure to a Glyphosate-Based Herbicide on Haematological Parameters, Plasma Biochemical Indices and the Microstructure of Selected Organs of the Common Carp ( Cyprinus carpio Linnaeus, 1758)

Contamination of water environments with herbicides is a common problem nowadays. The aim of the current study was to evaluate the effects of Roundup on common carp ( Cyprinus carpio) after 1, 3 and 10 days of exposure. The used concentrations corresponded to 1 and 5 mg/l of the active ingredient (glyphosate potassium salt). The haematological analysis performed showed a decrease of the RBC count, as well as an increase of the other erythrocyte indices (Hb, MCV, MCH, MCHC). Most of these changes were dependent on the concentration and time. An increase of the WBC count and the percentage of immature neutrophils occurred, thus indicating the presence of inflammation. In the studied blood biochemical parameters, only minor and temporary changes were observed. The histopathological analysis revealed no alterations in the gills, liver and kidney. Thus, the results of the present study suggest that the haematological parameters are more sensitive and reliable markers of the common carp's exposure to Roundup than the other parameters that were tested.

Гематологічні показники та якість сперми баранів у період статевого спокою за згодовування ліпосомальної вітамінно-мінеральної добавки

The aim of the work was to investigate the effect of feeding a liposomal vitamin and mineral supplement during the period of sexual rest on hematological indicators and quality of ram sperm. The experiment was conducted at the PE “Kogut BM” in Horodotsky district, Lviv region, on 12 clinically healthy Texel rams, aged 2–4 years, during the period of sexual rest (March-May). Animals were divided into two groups — control and experimental, 6 animals per group. The control rams received the basic diet containing hay, corn silage, and compound feed. For 45 days, the sheep of the experimental group were individually added to the combined feed a feed additive containing vitamins A, D3, E, C and zinc gluconate in the form of a liposomal emulsion. At the beginning and at the end of feeding, we took blood samples, in which hematological indicators were determined. After the end of supplement feeding, ejaculates were collected twice a week in doublets for three weeks. Physiological indicators of ejaculate quality (volume, sperm concentration, percentage of live sperm, as well as sperm viability, morphological disorders and percentage of degenerative sperm) were determined using the CASA computerized system. It was established that feeding liposomal vitamin-mineral supplements to rams during the period of sexual rest improves hematological indicators: the content of erythrocytes, hemoglobin, platelets and hematocrit increase significantly (P&lt;0.05–0.001) while the content of leukocytes decreases by 24.2% (P&lt;0.05). Accordingly, the erythrocyte indices of the blood of experimental breeding rams were higher than those of control animals. Feeding rams with a liposomal vitamin and mineral supplement ensured an increase in ejaculate volume by 17.6% (P&lt;0.05), sperm concentration (P&lt;0.01), their viability, as well as a decrease in the number of immature (P&lt;0.001) and degenerated (P&lt;0.05) sperm. Higher quality indicators of ejaculates of rams under the influence of vitamins A, D3, E, C and zinc gluconate indicate the possibility of obtaining sperm from breeding rams during the period of sexual rest.

Maternal diabetes and the role of neonatal reticulocyte hemoglobin content as a biomarker of iron status in the perinatal period.

We aimed to evaluate the effects of maternal diabetes on neonatal iron status, measuring erythrocyte indices including hemoglobin, hematocrit, reticulocytes, mean corpuscular volume (MCV), percent (%) hypochromia, ferritin, and additionally mean reticulocyte hemoglobin content (MCHr) as an early marker of iron deficiency, and examine the association between neonatal MCHr, red cell indices, and ferritin. We conducted a hospital-based prospective cohort study in a tertiary neonatal unit of a University Hospital from 2018 to 2020. We enrolled 126 maternal-infant pairs of mothers whose pregnancy was associated with diabetes and 74 maternal-infant pairs from uncomplicated pregnancies. Erythrocyte indices were analyzed within the first twelve hours after birth. Erythrocyte parameters were compared between infants of the diabetes and the non-diabetic group. We examined the correlation of the neonatal MCHr with perinatal characteristics, including gestation, birth weight, maternal body mass index, the erythrocytic indices, maternal diabetes, maternal obesity, prematurity, small-for-gestational-age status, maternal preeclampsia, and maternal anemia. Finally, we evaluated the discordance between neonatal MCHr and neonatal ferritin. Infants of the diabetes group had a significantly lower MCHr (32.6 pg vs. 34.2 pg, p=0.003) compared with infants of uncomplicated pregnancies. Neonatal MCHr was significantly correlated with maternal hypochromia (r=-0.237, p=0.004) and neonatal MCV (r=0.674, p<0.001). Neonatal MCHr was significantly associated with maternal diabetes [standardized coefficients 0.21, 95% confidence interval (CI) 0.05-0.58, p=0.003) and maternal preeclampsia (standardized coefficients 0.17, 95% CI 0.02-0.92, p=0.019), after adjusting for maternal anemia, maternal obesity, prematurity, and small-for-gestational-age status. Those results were consistent also when analyzing maternal-infant pairs with pre-existing diabetes, and maternal-infant pairs with gestational diabetes. There was significant discordance between neonatal MCHr and neonatal ferritin (p=0.001). MCHr was significantly lower in infants of mothers whose pregnancy was associated with diabetes compared with infants of non-diabetic mothers and correlated with neonatal and maternal red cell indices of iron deficiency. Since there was significant discordance between neonatal MCHr and ferritin during the first postnatal day, it is possible that MCHr could be used as a screening test for iron deficiency, especially in infants.

Parameters of Iron Metabolism in Patients with Iron Deficiency Anemia and Erosive Lesions of the Gastroduodenal Zone

The most common disease in the world is erosive-ulcerative lesions of the gastroduodenal zone (EULGZ). These are chronic polyetiological, recurrent diseases with disruption of the neuro-endocrine and humoral mechanisms that regulate the secretory-trophic process in the gastroduodenal zone with the development of ulcers. In this disease, ulcers have different localization and clinical course, significantly reduce the quality of life, affect work capacity and personal life. Lack of timely diagnosis and treatment can have adverse consequences. The objective: to analyse the characteristics of clinical and metabolic disorders in iron deficiency anemia (IDA) and its combination with EULGZ in order to develop the methods for assessing the disease severity, optimizing diagnostics and treatment tactics. Materials and methods. The observation group included 26 patients (15 men and 11 women) with iron-deficiency anemia (IDA) on background of EULGZ with localization of ulcerative defects of the mucous membrane in the stomach or duodenal bulb. The diagnosis of IDA was verified on the basis of changes in the basic characteristics of clinical manifestations (signs of anemic hypoxia and sideropenic syndrome), specific changes in peripheral blood and indicators of iron metabolism. Patients with IDA and EULGZ, were examined by endoscopic methods, underwent ultrasound and, if necessary, radiological examination. The control group included 35 primary donors (16 women and 19 men), who underwent two laboratory tests for hepatitis B and C, as well as HIV infection/AIDS. All examined donors underwent a comprehensive examination of peripheral blood and determined biochemical indicators. The indicators of iron metabolism were determined in all participants: iron content in the blood serum (IS), total iron-binding capacity of the blood serum (TIBS). The index of unsaturated iron-binding capacity of blood serum was calculated as the difference between TIBS and IS. The coefficient of transferrin saturation with iron was determined as the ratio of the content of IS to TIBS. The content of transferrin was determined according to the TIBS indicator, ferritin – by the radiometric method. Results. Peripheral blood indicators in primary donors and morphometric changes in peripheral blood in patients with IDA were analyzed. The results of investigations of the indicators of iron exchange in blood serum are presented: iron concentration, total iron-binding capacity of serum and the degree of saturation of serum with iron. It was found that male donors have significantly higher levels of iron and ferritin in blood serum compared to female donors. The dynamic of changes in peripheral blood parameters in patients with IDA caused by long-term blood loss due to EULGZ during the treatment process is shown. Treatment of the EULGZ led to the significant changes of such indicators as the number of erythrocytes, hemoglobin concentration, erythrocyte indices towards normalization. The normalization of the reticulocyte count was observed on the 90th day of treatment. The detected changes in the number of platelets in patients with IDA due to EULGZ were observed in the absence of active bleeding from the digestive tract. Conclusions. As a result of the progression of IDA due to the erosive-ulcerative lesions of the gastroduodenal zone, the imbalance of iron metabolism deepens, serious disorders of iron metabolism develop, especially in the content of plasma ferritin. Patients with IDA caused by long-term blood loss as a result of EULGZ, should be prescribed a drug for oral use containing ferrous sulfate with a mucosa-protective effect at a dose of 2 mg/kg per day, followed by a decreased dose after normalization of the serum ferritin level.

Normal anemia caused by endocrine disease

Anemia is a common condition in patients with thyroid disorders. This paper focuses on demonstrating that changes in hemoglobin concentration, hematocrit, red blood cell count and erythrocyte indices influence the development of this pathology. The reduced half-life and decreased erythropoietin production of red blood cells and proliferation of blood cell precursors in the bone marrow made it possible to establish a relationship between the patient's symptoms and the prevailing laboratory findings between anemia and hypothyroidism.

Erythron and protein system in piglets blood under stress influence

The article presents the results of research on the development of adaptive syndrome in the system of erythron and protein of piglets at the effects of weaning stress. After one (anesthetic stage) and seven days (beginning of G.Selle's resistance stage), after the echoing, the adaptation of the erythron system was shown by a decrease in the number of red blood cells on the contrary of increasing the mean corpuscular volume and hemoglobin indicating the inhibition of erythrocytosis with simultaneous macrocytosis, and a decrease in mean Corpuscular hemoglobin concentration for 14.0–13.0 % that indicated hypochromia. In these stressful periods, the catabolism of protein substrates was discovered, the redistribution of albumins between blood and tissues in the form of a decrease in the total protein content by 6.1–7.1 % due to albumin by 14.8–10.0 %, and the deficit of the humoral link of the immune response due to reduction of γ-globulins by 29.9–18.7 %. In the later stages of the resistance stage (after 20 and 60 days after weaning), there was a stabilization of erythrocytic indices and the development of anisocytosis in the form of an increase in red cell distribution width by 19.0 %, with a simultaneous decrease of 6.1 % of the total protein content, redistribution of its fractions in the side of the growth of γ-globulins by 18.4 %. A practical, prolonged way of preventing disorders in the erythron and protein of extramarital piglets was feeding the additive “Biovir”, which stimulated the intensity of oxidative-reducing processes and the exchange of proteins.
