The effect of imatinib and nilotinib on blood calcium and blood potassium levels in chronic myeloid leukemia patients: a literature review.

Imatinib and nilotinib are first-line treatments for chronic myeloid leukemia (CML) patients, which act specifically against target cells. However, these drugs may cause side effects, such as electrolyte disturbances. This literature review aimed to provide a comparison of the effects of imatinib and nilotinib on blood potassium and calcium levels. It also summarized their hypothetical mechanism. A comprehensive electronic search of the different databases was conducted using 'chronic myeloid leukemia', 'tyrosine kinase inhibitors', 'imatinib', 'nilotinib', 'potassium', 'calcium', 'electrolytes' as keywords. This review used PubMed- MEDLINE, Cochrane Library, and Google Scholar as the source databases. Sixteen articles published from 2006 to 2020 were reviewed. Changes in blood potassium levels range from increased to decreased levels, while changes in blood calcium levels range from the lower normal values to below normal values (hypocalcemia). Tyrosine kinase inhibitors (TKIs), including imatinib and nilotinib, have a non-specific target, namely plateletderived growth factor receptor (PDGFR), which indirectly affects blood potassium and calcium levels in CML patients. The clinical manifestations of these changes vary from being visible only in laboratory tests to displaying a variety of clinical signs and symptoms.

Use of reverse transcription loop-mediated isothermal amplification combined with lateral flow dipstick for an easy and rapid detection of Jembrana disease virus.

Jembrana disease virus (JDV) is a viral pathogen that causes Jembrana disease in Bali cattle (Bos javanicus) with high mortality rate. An easy and rapid diagnostic method is essential for further control this disease. We used a reverse transcription loop-mediated isothermal amplification (RT-LAMP) combined with lateral flow dipstick (LFD), based on conserved tm subunit of Jembrana disease virus env gene. The RT-LAMP conditions were optimized by varying the concentration of MgSO4, betaine, dNTP, and temperature as well as the time and duration of reaction. The primers sensitivity for JDV was confirmed. The method was able to detect env-tm gene dilution which contained 2 × 10(-15) g of template. Comparatively, the sensitivity of RT-LAMP/LFD was 100-fold more sensitive than reverse transcription-polymerase chain reaction. The primers specificity for JDV was also confirmed using positive and negative controls. This work also showed that virus detection could be done not only on total RNA extracted from blood but various organs could also be analyzed for the presence of JDV using RT-LAMP/LFD method. The whole process, including the LAMP reaction and the LFD hybridization step only lasts approximately 75 min. Results of analysis can be easily observed with naked eyes without addition of any chemical or further analysis. The combination of RT-LAMP with LFD makes the method a more suitable diagnostic tool in conditions where sophisticated and expensive equipments are not available for field investigations on Jembrana disease in Bali cattle.
