Anemia on period, Tratamentul cu leflunomid la un caz de poliartrită reumatoidă care asociaza anemie Biermer


The presence of anemia, regardless of the cause or mechanism, in oncologic patients adversely affects the quality of life, the outcome of the neoplastic disease and the adherence to treatment.

The mechanisms involved in the appearance of anemia in oncologic patients are intricated. Iron deficiency is a frequent cause of anemia in oncologic patients.

In anemia on period patients, the pre­va­lent mechanism for iron deficiency is the functional mechanism.

In this case, the iron stores are reduced due to the underlying oncologic condition or due anemia on period inflammatory processes associated to cancer treatments. Iron deficiency in cancer patients is often underestimated, mainly due to the difficulty of defining iron deficiency on the basis of usual laboratory markers.

The current therapeutic options of cancer anemia include blood transfusions, iron substitution and erythropoietin-stimulating agents.

Keywords cancer anemia, iron deficiency, anemia treatment Rezumat Anemia este o complicaţie frecventă la pacienţii oncologici, fiind întâlnită atât la momentul diagnosticului, cât şi în cursul terapiilor oncologice. Prezenţa anemiei, indiferent de cau­ză, la pacienţii oncologici are un impact negativ asupra ca­li­tă­ţii vieţii, a prognosticului bolii şi a aderenţei la tratament. Me­ca­nis­mele de producere a anemiei la pacienţii oncologici sunt multiple, putând fi determinată de malabsorbţie şi mal­nu­tri­ţie, sângerare acută sau cronică, inflamaţie sistemică, in­fil­tra­re metastatică a măduvei osoase şi de mielosupresie se­cun­da­ră tratamentului.

Deficitul de fier la pacienţii cu can­cer este una dintre cele mai frecvente cauze de anemie. Este în­tâl­nit la aproape jumătate din pacienţii cu tumori solide şi he­ma­to­lo­gice. La pacienţii cu boală oncologică, mecanismul pre­do­mi­nant al deficitului de fier este cel funcţional, anemia on period fie­ru­lui fiind redusă din cauza bolii sau a proceselor inflamatorii le­ga­te de terapie.

Deficitul de fier la pacienţii cu cancer ră­mâ­ne adesea subevaluat, în mare parte din cauza dificultăţii de­fi­ni­rii acestuia pe baza markerilor de laborator uzuali.

Cuvinte cheie anemia în cancer deficit de fier terapia anemiei Introduction Anemia is a frequent complication in cancer patients, both with solid and haematological tumors, and negatively influences the quality of life, the performance status and the prognosis of these patients.

It is important to anemia anemia on period period this condition rapidly and to manage and treat it, and consequently to improve the quality of life, the tolerability and adherence to cito­toxic treatment and the response to oncologic treat­ments. The data available show that the frequency of anemia in cancer patients is very high.

The increased incidence of anemia in oncologic patients is associated with the type of oncologic disease, the advanced stage of the disease and previous treatments. As for the type of disease, anemia is more common in haematological diseases compared to solid tumors.

In solid neoplasia, anemia is commonly associated with bronchopulmonary, breast, gastrointestinal and gyne­cological cancers 2,3. Mechanisms involved in anemia and iron deficiency in oncologic patients The mechanisms involved in the occurrence of anemia in cancer patients are multiple and complicated, with several mechanisms responsible for anemia occurring anemia on period the same time or at different times 4.

By reviewing the most important mechanisms of anemia, these may be acute or chronic bleeding, commonly found in gynecological tumors and digestive tract. The nutritional deficiencies of iron, vitamin B12 and folate, determined by malnutrition or malabsorption, are other common causes of anemia in these patients. Bone marrow infiltration by metastatic disease is frequently found in patients with anemia and breast or prostate cancer.

Other causes in patients with neoplastic disease is the decline in the production of endogenous erythropoietin, seen in patients with cancer and associated chronic renal disease, or due to decreased response to bone marrow erythropoietin 2,5,6.

In terms of iron deficiency, it is classified into two types anemia on period absolute and functional. Absolute deficiency appears when the anemia on period storage are low and depleted. Functional deficiency is present when iron reserve is normal or increased, but the disponibility of iron for erythropoiesis is low due to inflammatory processes that cause iron blocking in macrophages and enterocytes.

The mechanism of functional iron deficiency in cancer patients is well known. Iron is taken by the transferrin from duodenal enterocytes or macro­phages that recycle the iron from aging erythrocytes and it is transported anemia on period the bone marrow 8. These mechanisms are controlled by hepcidin, which is an amino acid produced in the liver by peptic hepcidin anti-microbial genes at chromosome 19, in the pre­sence of cancer or chemotherapy-induced inflam­mation.

Hepicidin has the role of maintaining iron homeostasis 9. Hepcidin block the release of iron from the macrophages in anemia on period bone marrow by blocking ferroportin, which has the role to transfer the iron from the gastric mucosa to the transferrin.

The functional deficiency of iron occurs following the release of cytokines, especially inter­leukin-6, in the presence of inflammation, which results in hepcidin production increased in the liver. High levels of hepcidin are found in many types of hematological and solid cancers. Low levels of hepcidin have been observed in patients with hepatic metastases Evaluation of patients with anemia and iron deficiency Iron deficiency in cancer patients is a common state.

But it is anemia on period difficult to recognize it. Evaluating the profile of patients with iron deficiency, data available from studies show that patients with tumors of the colon, rectum, pancreas and pulmonary syndrome have a very frequent iron deficiency. Also, patients with advanced disease and chemotherapeutic treatment have iron deficiency. It may anemia on period present even in the absence of anemia, it can influence the performance status of patients and may cause fatigue, an important and frequent sign 1,2.

In healthy people, ferritin anemia on period show the status of iron stores. Other parameters, such anemia on period transferrin saturation, the percentage of hypochromic erythrocytes, the soluble transferrin receptor and the reticulocyte hemoglobin anemia on period, show the amount of iron that is biologically available. All these markers are modified in cancer patients. Particularly ferritin, which is an acute phase protein, may not properly reflect iron deposits in cancer patients who have an inflammatory status.

Transferrin saturation assessment is recommended, but it has also limitations in cancer patients, because of the presence of inflammation or malnutrition that causes transferrin levels to be reduced, so normal or elevated false values may occur 14, The measurement of circulating hepcidin levels appears to be a useful tool in the diagnosis of iron deficiency anemia on period these patients, but is still under evaluation Moreover, the functional iron deficiency is difficult to diagnose and often remains unnoticed and consequently untreated.

It is therefore important to evaluate in details the iron profile of the patients, in order paraziti v blatu highlight the presence of iron deficiency. Additional studies are also needed to evaluate more precisely the biomarkers that can be used in the diagnosis of iron deficiency, especially the functional deficiency.
