RESUMO
OBJECTIVE: This study aimed to compare the reticulated platelet count between patients having thrombocytopenia secondary to autoimmune destruction (immune thrombocytopenia {ITP}), bone marrow failure, and healthy controls who presented to a tertiary care hospital in Karachi, Pakistan. METHODOLOGY: A cross-sectional study was conducted from February 2021 to October 2022 in the Department of Hematology, National Institute of Blood Disease (NIBD) Hospital in Karachi, Pakistan, that involved examining three groups: 30 patients with immune thrombocytopenia, 30 patients with thrombocytopenia secondary to reduced production from bone marrow, and 30 healthy controls. The study utilized the Sysmex XN-1000 (Hyogo, Japan: Sysmex Corporation) automated hematology analyzer to perform a complete blood count (CBC) test. Additionally, peripheral blood was stained with Leishman stain and examined under a microscope to eliminate pseudo thrombocytopenia and identify any abnormal cells or dysplasia. The immature platelet fraction (IPF) was then performed on Sysmex XN 1000 after ensuring adequate quality control. Finally, the data were analyzed using DATAtab (Graz, Austria: DATAtab) and SPSS version 25 (Armonk, NY: IBM Corp.). RESULTS: Of the ninety participants, the median age was 33 years with a range of 18-71 years. Patients with ITP had a significantly higher median IPF% (median=26.65, IQR=15-39.4) than thrombocytopenia due to bone marrow failure (median=9.25, IQR=4.55-14.30) and healthy controls (median=7, IQR=4.40-9.90), with a p-value of 0.001. The immune thrombocytopenia group demonstrated an increase in IPF% as platelet counts increased, indicating a significant moderate correlation between IPF% and platelets in these patients (r=0.438, p=0.016) and confirming that IPF% was an independent predictor for the detection of ITP. CONCLUSION: Reticulated platelet count may be a useful diagnostic tool to differentiate between ITP and thrombocytopenia caused by bone marrow failure. Because of its non-invasive nature, IPF is a valuable tool for expediting the management of thrombocytopenia associated with increased IPF.
RESUMO
Aim and objective This study aimed to examine the relationship between serum ferritin levels and the degree of hepatic fibrosis as detected on Fibroscan in thalassemia patients. Materials and methods This was a single-center and cross-sectional study conducted from April 2021 to December 2022. The sample population comprised 55 beta-thalassemia patients receiving treatment at the National Institute of Blood Diseases and Bone Marrow Transplantation, Karachi, Pakistan. The data was compiled through a series of patient interviews, an examination of medical records and was analyzed to obtain the results. Descriptive statistics were used for several variables, including diagnosis, Fibroscan score, blood group, comorbidity, visceromegaly, consanguinity, serum glutamate pyruvate transaminase (SGPT), viral markers, and C reactive protein (CRP). The correlation analysis was done using Spearman's correlation test. Results There were 55 participants in the study, 40 of whom were male and 15 of whom were female. The mean age of the patients was eight years, while the average age at diagnosis was nine months with a transfusion frequency of every 20 days. Spearman's rho (r = 0.287), and the significant value of (p = 0.033) confirmed a statistically significant positive correlation between serum ferritin levels and hepatic fibrosis. On Fibroscan, 74.5% of patients had F0-F1 stage fibrosis followed by 14.5% of the patients having F2 stage fibrosis. HCV seropositivity was the most prevalent comorbidity among the patients. 80% of patients had serum ferritin levels greater than 1000 ug/mL. Hepatosplenomegaly was present in 43.6% of the patients. 78.2% of patients were born out of consanguineous marriages. Conclusion In conclusion, this study found a statistically significant positive correlation between serum ferritin levels and hepatic fibrosis in beta-thalassemia patients. The study emphasizes the significance of monitoring serum ferritin levels in thalassemia patients to prevent hepatic fibrosis.
