Introduction: Polycythemia is a rare condition that can be either primary or secondary. We report a case of an adolescent with progressive hydronephrosis-induced polycythemia and low erythropoietin levels, along with a thorough literature review.
Report Of A Case: A 17-year-old girl with epilepsy had progressively elevated hemoglobin levels and low erythropoietin levels. Initial investigations, including genetic surveys and bone marrow studies, showed no evidence of polycythemia vera or myeloproliferative disorders. Further imaging studies revealed severe hydronephrosis on the left side caused by ureteropelvic junction stenosis. Following nephroureterectomy, her hemoglobin levels gradually returned to normal.
Conclusions: This case highlights the potential association between hydronephrosis and polycythemia, even with low erythropoietin levels. Renal abnormalities should be considered in the differential diagnosis of pediatric patients with polycythemia, even in the absence of elevation of erythropoietin. Further research is needed to clarify this association and its pathophysiology.

The most severe form of α-thalassemia results from loss of all four copies of α-globin. Postnatally, patients face challenges similar to β-thalassemia, including severe anemia and erythrotoxicity due to the imbalance of β-globin and α-globin chains. Despite progress in genome editing treatments for β-thalassemia, there is no analogous curative option for α-thalassemia.

Aims: The term ovarian carcinoma (OC) refers to a heterogeneous collection of five distinct diseases known as histotypes. While histotype-specific treatment is still a clinical challenge in OC, well-characterized models are required for testing new therapeutic strategies. We employed OncoTherad® (MRB-CFI-1), an interferon (IFN-γ)-stimulating nano-immunotherapy mediated by Toll-like receptors (TLR) 2/4, in association or not with Erythropoietin (EPO) in a chemically-induced ovarian cancer model.

Rationale: Postpartum iron deficiency anaemia is caused by antenatal iron deficiency or excessive blood loss at delivery and might affect up to 50% of labouring women in low- and middle-income countries. Effective and safe treatment during early motherhood is important for maternal well-being and newborn care. Treatment options include oral iron supplementation, intravenous iron, erythropoietin, and red blood cell transfusion.

Vitamin A deficiency (VAD) and iron deficiency anemia coexist around the world, particularly in children and women of reproductive age in low- and middle-income countries. Within this scenario, there is a known interaction between vitamin A and iron, and it has been postulated that lack of vitamin A impairs iron metabolism, leading to vitamin A deficiency anemia (VADA). Current animal, epidemiological, and clinical studies support this notion.
