RESUMO
Background: Even though the incidences of hematologic malignancies have received considerable attentions globally, there is paucity of information on patterns of hematologic malignancy in Eritrea. The study was conducted to determine the distribution of various hematologic malignancies among patients who have received bone marrow examination, in the Eritrean National Health Laboratory. Methods: A retrospective descriptive study design was used to determine the patterns of Hematologic malignancies diagnosed at the Eritrean National Health Laboratory from October 2015 to July 2017. Results: Out of 207 patients who did bone marrow aspiration 52 patients were hematologic malignancy cases. The male to female ratio was 1:1. The age of the patients ranged from 2 to 80 years. Of the 52 patients 19, were less than 20 years of age and the remaining 33 were 20 years and above. Acute leukemia was the most common hematologic malignancy in the study area. It affected 18 of the cases followed by chronic myelogenous leukemia, chronic lymphocytic leukemia, myelodysplastic syndromes, multiple myeloma, and myeloprofilerative neoplasms. The presenting signs and symptoms in their decreasing frequency were generalized body weakness/fatigue, splenomegaly, fever, anemia, and lymphadenopathy. More than two-third of the patients had total leukocyte count greater than 10,000/µl. Conclusion: This study shows that hematologic malignancies are not uncommon in Eritrea.
RESUMO
False-negative results for Plasmodium falciparum histidine-rich protein (HRP) 2-based rapid diagnostic tests (RDTs) are increasing in Eritrea. We investigated HRP gene 2/3 (pfhrp2/pfhrp3) status in 50 infected patients at 2 hospitals. We showed that 80.8% (21/26) of patients at Ghindae Hospital and 41.7% (10/24) at Massawa Hospital were infected with pfhrp2-negative parasites and 92.3% (24/26) of patients at Ghindae Hospital and 70.8% (17/24) at Massawa Hospital were infected with pfhrp3-negative parasites. Parasite densities between pfhrp2-positive and pfhrp2-negative patients were comparable. All pfhrp2-negative samples had no detectable HRP2/3 antigen and showed negative results for HRP2-based RDTs. pfhrp2-negative parasites were genetically less diverse and formed 2 clusters with no close relationships to parasites from Peru. These parasites probably emerged independently by selection in Eritrea. High prevalence of pfhrp2-negative parasites caused a high rate of false-negative results for RDTs. Determining prevalence of pfhrp2-negative parasites is urgently needed in neighboring countries to assist case management policies.
