ABSTRACT

Background:

Patients with inadequate amounts of copper often present with cytopenias and exhibit dysplasia on bone marrow, mimicking myelodysplastic syndrome (MDS) and pose diagnostic difficulties. Method(s) This cross-sectional observational study was performed from January 2020 to June 2021. Patients diagnosed with MDS were included in the study and serum copper levels were measured by the Inductively Coupled Plasma Mass Spectrometry (ICPMS) method. Copper supplementation with intravenous copper chloride 2.5mg daily for the first two weeks, followed by oral 3mg copper sulfate thrice daily for the next three months, was given for copper-deficient patients. Response assessment was performed with repeat hemogram and serum copper levels. Result(s) A total of 57 patients were diagnosed with MDS, of these, 33 (57.89%) were males and 24 (42.10%) were females. The mean age was 54.3+/-14.6 years (13-81). The distribution of patients in different types of MDS was MDS-SLD in 15, MDS-MLD in 18, MDS-EB1 in 7, MDS-EB2 in 8, and MDS-U in 9 patients. Anemia was seen in (87.71%) of patients, with mean hemoglobin 7.6+/-2.1g/dL (4.6-14.5g/dL). Neutropenia was seen in 31 (54.38%) with a mean absolute neutrophil count(ANC) of 2073+/-2139/muL (211-10,952/muL). Thirty seven (64.91%) patients had thrombocytopenia with a mean platelet count of 1,05,298+/-1,21,769/muL (9,000-6,74,000/muL). The mean serum copper levels were 146.69+/-42.36mug/dL (54.2-254.0mug/dL). Only three (5.26%) patients out of 57 were found to have copper deficiency. All three patients with low copper levels were found to have anemia, thrombocytopenia, and mildly raised serum erythropoietin levels. All three patients had dyserythropoiesis on bone marrow examination, and only one patient each had cytoplasmic vacuolations in erythroid precursors and dysmegakaryopoiesis. Among the three patients with copper deficiency, two patients had significant improvement in cytopenias after copper supplementation, and one had lost follow-up due to COVID-19. Conclusion(s) This study is the first from India to evaluate the role of copper in patients presenting with predominantly hematological manifestations. For patients presenting with cytopenias or marrow dysplasia resembling MDS, copper deficiency should be considered in the differential diagnosis. Legal entity responsible for the study The authors.
