Abstract

Plasma cell leukemia (PCL) is a scarce hematology malignancy with challenging clinical picture and dismal prognosis. The diagnostic procedure is sometimes complicated and difficult due to its scarcity. Patient was a 54-year-old male who presented with generalized weakness 2 months prior to hospital admission. He had anemia, thrombocytopenia and leukocytosis with 96% blasts. Initial peripheral blood smear showed unspecific cells that turned out to be plasmacytes. Flow cytometry showed positive for CD38, CD138, Kappa, CD43 and CD200, with conclusion of myeloma. Confirmation with serum protein electrophoresis showed gamma migrating paraprotein with 35.5% gamma Ig G, reduced albumin fraction and alpha 1 globulin. There was M-spike on gamma globulin. Serum immunofixation electrophoresis (SIFE) on the next day showed oligoclonal gammopathy (bi-clonal IgG Kappa and monoclonal Kappa light chain). Based on those results, patient was diagnosed with primary plasma cell leukemia. Diagnosis of PCL is often challenging and misleading due to the clinical features resembling multiple myeloma and unspecific morphology of plasma cell. Peripheral plasmacyte >5% with M-spike on gamma globulin in SPE and gammopathy oligoclonal in SIFE (bi-clonal IgG Kappa and monoclonal Kappa light chain) were supported the diagnosis of PCL and confirmed by the positive flow cytometry for CD38, CD138, Kappa, CD43 and CD200. Therefore, utilization of modern diagnostic procedures like flow cytometry is crucial to make the diagnosis of this rare disease

Abstract

The Bioneer AccuPower®HIV-1 Quantitative renewed the LoD from 38 IU/mL to 33 IU/mL. Performance evaluation of the kit has not been carried out in Indonesia since the alteration, as it is expected that the new kit will have improved sensitivity. This study is a cross-sectional evaluation of the correlation, sensitivity, and specificity of the Bioneer-AccuPower HIV Quantitative RT-PCR Kit compared to the Roche-Cobas 4800 System HIV-1. We obtained venous EDTA plasma from 211 HIV patients tested in the Clinical Pathology Laboratory of Dharmais Hospital, Indonesia. Subject werw  71 high-viral-load samples (>1000 copies/mL), 60 low-viral-load samples (<1000 copies/mL), and 80 undetectable-viral-load samples (<14.2 copies/mL/<24.42 IU/mL). Exclusion criteria were samples under the limit of quantification of each instrument (Roche-Cobas®4800 20 copies/mL (34.4 IU/mL); Bioneer-AccuPower 69.4 copies/mL (49.97 IU/mL)). Ethical Declaration released by Dharmais Hospital Ethical Committee No.DP.04.03/11.7/0872024. The categorical contingency correlation in determining whether the HIV viral load sample was high, low, or undetectable was 0.863. The sensitivity, specificity, and accuracy of the Bioneer-AccuPower HIV Quantitative RT-PCR Kit, compared to the Roche Cobas 4800 System HIV-1, in quantifying HIV viral load were 99.15%, 96.25%, and 98.10%, respectively. Regarding the limit of quantification of each instrument, the Bioneer-AccuPower HIV Quantitative RT-PCR Kit performed well in determining HIV RNA viral loads, making it suitable for HIV screening. It exhibits a strong correlation compared to the Roche Cobas® 4800 System HIV-1. However, it required a larger study that did not limit the sample according to the limit of quantification of both instruments and sequenced the discrepancy samples.
