RESUMEN
Plasmodium falciparumconsidered as the most serious form of species causes malaria compared with other species. Diagnosis of falciparummalaria in Sudan remain a major problem, the laboratory diagnosis depends solely on microscopy and RDTs. Loop mediated isothermal Original Research Article amplification (LAMP) assay is a molecular technique done in isothermal temperature using simple, inexpensive instruments for detection of falciparummalaria. The aim of the study is to evaluate the diagnostic performance of loop mediated isothermal amplification (LAMP) assay for detection ofP. falciparumand compare with microscopic detection. A cross sectional hospital based study conducted on 220 blood samples collected from participants suspected to have falciparum malaria attending Wad Medani Teaching Hospitalsand 26 healthy participants during the period November 2018 to January 2019. Thick blood films were done and used for P. falciparum detection. The extracted DNA by TE buffer was amplified by LAMP assay targeting 18S rRNA gene. Data were analyzed using Medical calculator (MedCalc) programs (V. 16). The results showed that the sensitivity, specificity, positive predictive value, negative predictive values were 99.1%, 84.6%, 53.2%, 99.8% respectively. Validation of LAMP diagnostic performance revealed that area under the curve is 0.919, while Weighted Kappa is 0.866. The study concluded that the LAMP assay had the identical diagnostic performance compared with microscopy in diagnosis of Plasmodium falciparum malaria. This gives a relative effortlessness application of LAMP assay in Sudan after availing the required logistics
RESUMEN
Background and Study Aims: Hepatitis C virus [HCV]-related cirrhosis is the leading cause of liver transplantation[LT]. All patients who undergo LT with detectable serum HCV-RNA experience graftreinfection, which is the most frequent cause of graft loss and death in these patients. We estimated the rate of HCV recurrence and evaluated the current therapeutic regimens
Patients and Methods: The records of consecutive 325 living donor LT [LDLT] surgeries performed between May 2004 and August 2014 were retrospectively analysed; 207 of them were followed-up throughout the study. Clinical, laboratory, radiological and histopathological examinations were performed thoroughly. Patients received treatment in the form of either pegylated interferon [PEG-IFN] or sofosbuvir, both in combination with ribavirin
Results: In total, 90.3% of recipients who were transplanted because of HCV-related end-stage liver disease experienced recurrence due to the virus. The donor age was older in the HCV recurrent group versus the non-recurrence group [28.7 +/- 7.1 versus 22.6 +/- 2.6 years: p
Conclusions: Older donor age and prolonged warm ischaemia time are independent predictors of HCV recurrence after LDLT, and early treatment with the direct-acting sofosbuvir is helpful in resolving the problem of post-LT HCV recurrence
