OPTIMIZATION OF DIAGNOSIS OF SECONDARY METABOLIC DISORDERS AND TREATMENT TACTICS IN PATIENTS WITH ANEMIA IN NEOPLASTIC DISEASE IN COLORECTAL CANCER

Colorectal cancer is one of the most common oncological diseases, therefore, the study of this problem is an important issue in clinical practice. This problem becomes especially urgent in case of the formation of anemic syndrome in patients, which causes the emergence of a mutual burden syndrome and increases the risks for a patient. The progressive nature of anemia in colorectal cancer is accompanied by secondary metabolic disorders. The material for the study was the blood plasma of 445 patients (228 men and 217 women). Among them, 53 patients (31 women and 22 men) with iron deficiency anemia were examined and included in the first observation group (І) and 392 patients (206 men (52,55 %) and 186 women (47.45 %)) with colorectal cancer whose course of the underlying disease was burdened with anemia in neoplastic disease were included in the second observation group (II). Among the patients in the second (II) observation group, there were 222 individuals (119 men and 103 women) with malignant neoplasms of the colon (ICD-10 code: С.18), 29 individuals (16 men and 13 women) with malignant neoplasms of the rectosigmoid junction (ICD-10 code: C.19), 138 individuals (82 men and 56 women) with malignant neoplasms of the rectum (code ICD-10 C.20) and 3 patients (2 men and 1 woman) with malignant neoplasms of the anus (ICD-10 code: C.21). The age of the examined patients was from 22 to 79 years. It was found that prior to the initiation of treatment in patients with anemia in neoplastic disease, regardless of the course of colorectal cancer, there was a significant increase in the plasma level of free fractions of heparin, histamine and serotonin (p < 0,001); the ratio of histamine: serotonin was also changed in comparison with the values in the control group (p < 0,05), which indicated both an increased release of heparin, histamine and serotonin from the depot, and an impaired inactivation processes of these biologically active substances. It was correctly concluded that in addition to the baseline therapy the administration of arginine glutamate which causes both antihypoxic and membrane-stabilizing action, reliably contributes to the normalization of secondary metabolic disorders of histamine, serotonin and heparin metabolism in anemia in neoplastic disease in patients with colorectal cancer.

IRON DEFICIENCY ANEMIA

Objectives: To determine the importance of the RDW and other red cell indices(MCV, HBG) in the prediction of iron deficiency anemia in third trimester of pregnancy in a tertiarycare hospital of Peshawar. Design: Cross sectional study. Setting: OPD Department ofGynecology and Obstetrics Postgraduate Medical Institute, Lady reading Hospital (PGMI-LRH)st th Peshawar. Period: 1 August 2012- 10 Dec 2012. Material and Methods: A Total of 152 womenattending the centre were included. Necessary information’s were recorded on the questionnaireprepared in accordance with the objectives of the study. Results: A total of 152 women in theirthird trimester presenting to Gynecology and obstetrics department of Lady reading hospitalPeshawar. The age range of the patient was from 20 years to 55 years with mean age of33+3.4years.Out of total 27(18%) were primagravida. Majority of the cases 118(77.6%) werefrom Peshawar, 9% from charsadda, 8% nowshera etc. We also received 2 patients 1.2% fromAfghanistan. Regarding financial status 57 %( 87) females were in upper Class ( i.e. income>20000/month) on recall. Of total 81(53%) of the females were having hemoglobin less than11g/dl and 22% of the women had HCT<32% which as per criteria of the WHO were anemic at thetime of presentation. While 29(19%) patients had low value of MCV (microcytic). Fifty five patients(36.2%) had RDW CV(%) more than 15% which points more towards the microcytic nature ofanemia and more anisocytosis. Conclusions: Fifty five patients (36.2%) had RDW CV(%) morethan 15% which points more towards the microcytic nature of anemia. While 29(19%) patientshad low value of MCV (microcytic). Increased RDW is best indicator for the detection of irondeficiency anemia than MCV. Increased RDW even in the presence of normal MCV can be anearly signal for iron deficiency anemia in pregnacy. Hence RDW is more reliable indicator for irondeficiency especially in pregnancy. Changes in RDW in last trimester is more significant that MCV.

Anaemia control and the interpretation of biochemical tests for iron status in children

BackgroundAnaemia is one of the world’s most prevalent child health problems. Its control in Africa and other developing nations has been hindered by uncertainty regarding its cause. Anaemia control has been particularly problematic in regions where the non-iron deficiency causes of anaemia, are projected to be substantial. The implementation of effective interventions to reduce the anaemia prevalence, requires improved documentation on iron status and other causes of anaemia for target populations.MethodsThis cross-sectional study enrolled n = 184 children, aged 6–8 years from Kwazulu-Natal, South Africa. Tests of haemoglobin, serum ferritin, soluble transferrin receptor and C-reactive protein were performed. These conventional measures of iron status were used to calculate body iron and to categorize the children into different groups of anaemia profiles.ResultsAnaemia prevalence was high, 43/184 (23.4%). Iron deficiency anaemia contributed 7/43 (16.3%) to the anaemia prevalence compared to non-iron deficiency anaemia 34/43 (79.1%) and mixed anaemia 2/43 (4.7%). In total 47/184 (25.5%) of the sampled children had either iron deficiency or anaemia. Information about the presence of inflammation was used to adjust serum ferritin concentrations, resulting in improved diagnosis of iron deficiency.ConclusionAppropriate investigations for iron status and inflammation/infection screening, need to be integral in the evaluation of anaemia and its causes before anaemia control interventions are implemented. Interventions that target the multifactorial nature of anaemia in school-aged children need to be strengthened. Additionally, regular screening of anaemia in school-aged children from disadvantaged communities is recommended.

Iron deficiency anemia in children younger than 1 year:the search for the formula of success of outpatient management of patients

172 newly diagnosed cases of iron deficiency anemia (IDA) in children younger than 1 year who were hospitalized in the Department of Hematology Saint Petersburg Сhildren Hospital No 1 in St Petersburg 2010-2015 were analyzed. Anamnesis peculiarities of IDA and outpatient care of babies, including individual prevention of iron deficiency and ferrotherapy and the causes of identified deviations from the existing patient management recommendations were clarified. Defects of sideropenia prevention found in all examined children. The fundamental error of pediatricians during ferrotherapy were the lack of verification of the nature of anemia, violation of drug dosing iron, lack of monitoring the effectiveness of treatment, failure to comply with the required duration of the courses of therapy. Mistakes made by pediatricians during the prevention, diagnosis and treatment of iron deficiency anemia are primarily a reflection of the deficit of basic knowledge of doctors on this issue. The effectiveness of the prevention of iron deficiency in infants is largely determined by the individual outpatient pediatrician, the level of his training, psychological stability and ability to engage constructively with the parents of patients. Components of success of outpatient management of patients younger than 1 year with iron deficiency are: the presence of a modern background knowledge on the issue, understanding the health and social consequences of iron deficiency for the younger generation and the desire to make a personal contribution to improving the health of children in Russia.

Induction of hyperchromic microcytic anaemia by repeated oral administration of methotrexate in rats

Anaemia is a significant prognostic factor in cancer patients receiving anticancer drugs such as methotrexate (MTX). This study focuses on the effects of toxicological changes on the hematopoietic systems in male and female Wistar Hannover rats when MTX is orally administered at a dose of 0, 0.05, 0.15, or 0.45 mg/(kg·day) for a period of 28 days. Both male and female rats receiving 0.45 mg/kg MTX showed a decrease in the haemoglobin concentration (Hb), haematocrit, and erythrocyte count. Female rats showed a decrease in mean corpuscular volume (MCV) and an increase in cell mean Hb (CHCM) in total erythrocytes, including the mature erythrocytes. These results indicate that MTX causes the production of small, mature erythrocytes that contain a high concentration of Hb. MTX reduced the number of peripheral reticulocytes but produced the cells with a large size and a high concentration of Hb, as demonstrated by the reticulocyte MCV and CHCM as well as the content of haemoglobin per reticulocyte (CHr). Consistent with these findings, bone marrow haematopoiesis was impaired by MTX, as there was a reduction in erythroid count in rats of both sexes. The number of cells of the myeloid lineage reduced in female rats, followed by a reduction in the total leukocyte and neutrophil counts in peripheral blood. Thrombocytopenia was detected in a small population of rats. These results indicate that MTX induces hyperchromic microcytic anaemia and pancytopenia, and the use of MCV and CHCM in mature erythrocytes and reticulocytes, along with the CHr, gives a better understanding of the development and nature of anaemia.

Prevalence and nature of anaemia in a prospective, population‐based sample of people with diabetes: Teesside anaemia in diabetes (TAD) study

Anaemia occurs in 25% of people attending hospital diabetes clinics, but this may not be representative of all people with diabetes. We aimed to determine the prevalence of anaemia in a prospective population-based sample stratified by estimated glomerular filtration rate (eGFR) using the 4-point Modification of Diet in Renal Disease (MDRD) formula. All 7331 patients on our district register were stratified by eGFR. Seven hundred and thirty were approached by letter on two occasions. Two hundred and thirty-four (32%) returned questionnaires and blood samples. Responders (R), non-responders (NR) and the whole cohort (C) were similar: mean +/- sd age R 61.7 +/- 12.7 years; NR 61.3 +/- 15.1 years; C 61.8 +/- 14.2 years; diabetes duration R 8.8 +/- 8.6 years; NR 8.2 +/- 7.9 years; C 7.5 +/- 7.8 years, Type 1 diabetes R 10.1%, NR 10.8%, C 9.4%. Anaemia was defined using World Health Organization criteria: haemoglobin < 13 g/dl for men, < 12 g/dl for women. Previously undiagnosed anaemia was present in 15% of the whole group, 36% with eGFR < 60 ml/min per 1.73 m(2) and 9% of those with eGFR > 60 ml/min per 1.73 m(2). Anaemia was as a result of erythropoietin deficiency in 34%, abnormal haematinics in 40% and was unexplained in 26% of patients. Five per cent of the patients had anaemia below the treatment threshold of 11 g/dl. The prevalence of unrecognized anaemia in population-based cohorts is lower than that in hospital-based studies. Current clinical surveillance in the UK is failing to detect anaemia in stage 3-5 chronic kidney disease (eGFR < 60 ml/min per 1.73 m(2)) and current guidelines will not detect 9% of diabetic patients with anaemia and an eGFR > 60 ml/min per 1.73 m(2).

Iron Deficiency: Contemporary Scientific Issues and International Programmatic Approaches

Iron deficiency is a common nutritional disorder in developing countries and contributes significantly to reduced work productivity and economic output as well as to increased morbidity and mortality. There are well established biochemical tests for assessing iron status in developed countries. However, cost and interference from infectious conditions make it difficult to assess iron status in many developing country settings. Examination of the hemoglobin distribution in the population and assessment of the hemoglobin response to supplementation are alternative approaches to defining iron status and the nature of anemia. Prevention and control of iron deficiency requires the combined approach of dietary improvement, fortification of a common staple food when feasible, and appropriate iron supplementation for infants and pregnant women. In all these intervention activities, operational research is needed to improve effectiveness. In addition, controlling iron deficiency requires coordination with other nutrition and primary health care programs as part of an integrated approach to improved health and nutrition of the population.

The prevalence and nature of anaemia among apparently normal subjects in fiji

A total of 4939 apparently healthy Fijian and Indian subjects living in Fiji were tested for anaemia by determination of the microhaematocrit of a sample of capillary blood. The prevalence of anaemia during childhood varied with age but was similar for Fijians and Indians of either sex. The overall prevalences were: 0-4 years, 20.3%; 5-9 years, 3.7%; 10-14 years, 23.5%. The prevalence of anaemia among Indian women (33.3%) was substantially higher than that for Indian men (6.9%), Fijian women (8.1%) or Fijian men (6.8%). Iron deficiency was the most common cause of anaemia and was established by laboratory studies in 203 (68%) of 298 anaemic subjects who were followed up. Iron deficiency was an important aetiological factor in 91 (93%) of 98 subjects with moderate or severe anaemia. Folate deficiency was found, usually in combination with iron deficiency, in 44 or 141 anaemic indian adults were followed up. Folate deficiency was uncommon in Fijian adults and among children of either race. Two cases of nutritional vitamin B12 deficiency, one case of pernicious anaemia, 6 cases of heterozygous thalassaemia and one case of heterozygous haemoglobin E were found among the anaemic Indian subjects. No cases of vitamin B12 deficiency anaemia, thalassaemia or haemoglobinopathy were detected among the Fijians. In 5 Indians and 7 Fijians the anaemia was associated with an underlying chronic disorder. This study emphasizes that in Fiji, as in other developing countries, nutritional anaemia is prevalent among asymptomatic subjects. Iron deficiency is by far the most common cause.

Two young men, were hospitalized due to acute massive blood loss with left abdominal flank pain. In both cases renal angiography showed signs of a haemorrhagic event in the left kidney, perirenal in one and subcapsular in the other. Microaneurysms indicated a diagnosis of polyarteritis nodosa, supported by renal biopsy in one case. Renal haemorrhage is an infrequent presentation of polyarteritis nodosa. Furthermore, one patient suffered also from familial Mediterranean fever, and is the fifth reported case with this combination of diseases.
