Erythropoietic protoporphyria (or commonly called EPP) is a form of porphyria, which varies in severity and can be very painful.It arises from a deficiency in the enzyme ferrochelatase, leading to abnormally high levels of protoporphyrin in the red blood cells (erythrocytes), plasma, skin, and liver.

Erythropoietin has been studied as a treatment option to reduce anemia in preterm infants. Treating infants less than 8 days old with erythropoietin may slightly reduce the need for red blood cell transfusions, but increases the risk of retinopathy. Due to the limited clinical benefit and increased risk of retinopathy, early or late ...
Haemochromatosis is protean in its manifestations, i.e., often presenting with signs or symptoms suggestive of other diagnoses that affect specific organ systems.Many of the signs and symptoms below are uncommon, and most patients with the hereditary form of haemochromatosis do not show any overt signs of disease nor do they have premature morbidity, if they are diagnosed early, but, more ...
A feedback loop involving erythropoietin helps regulate the process of erythropoiesis so that, in non-disease states, the production of red blood cells is equal to the destruction of red blood cells and the red blood cell number is sufficient to sustain adequate tissue oxygen levels but not so high as to cause sludging, thrombosis, or stroke ...
Erythropoietin (/ ɪ ˌ r ɪ θ r oʊ ˈ p ɔɪ. ɪ t ɪ n,-r ə-,-p ɔɪ ˈ ɛ t ɪ n,-ˈ iː t ɪ n /; [1] [2] [3] EPO), also known as erythropoetin, haematopoietin, or haemopoietin, is a glycoprotein cytokine secreted mainly by the kidneys in response to cellular hypoxia; it stimulates red blood cell production (erythropoiesis) in the bone marrow.
Ineffective erythropoiesis is defined by the expansion of early-stage erythroid precursors driven by erythropoietin, accompanied by the apoptosis of late-stage precursors. . This mechanism is principally responsible for the anemia seen in acquired conditions such as certain subtypes of myelodysplastic syndrome (MDS) and inherited disorders such as β-thalassemia, inherited sideroblastic ...
The 2020 Cochrane Anaesthesia Review Group review of erythropoietin (EPO) plus iron versus control treatment including placebo or iron for preoperative anaemic adults undergoing non‐cardiac surgery [11] demonstrated that patients were much less likely to require red cell transfusion and in those transfused, the volumes were unchanged (mean ...
Symptoms of this disease include seizures, hydrocephalus, and chorioretinitis. Cytomegalovirus : viral TORCH infection associated with sensorineural hearing loss , hepatomegaly , and jaundice . Rubella : viral TORCH infection associated with post-auricular and occipital lymphadenopathy in addition to a maculopapular rash that starts on the face ...
