Neurologické postižení je poměrně vzácná komplikace hepatitidy E. Uvedená kazuistika popisuje 52letého imunokompetentního muže s aseptickou meningitidou a mnohočetným postižením periferních nervů na horních končetinách typu mononeuropatia multiplex, u kterého byla sérologickým vyšetřením prokázána akutní virová hepatitida E. Navíc byl virus hepatitidy E zjištěn polymerázovou řetězovou reakcí v séru i likvoru (genotyp 3f). Pacient byl léčen pouze symptomaticky, po půl roce přetrvával mírný neurologický deficit. Infekci virem hepatitidy E je vhodné zvažovat u pacientů se současným neurologickým a jaterním postižením., Neurological complications of acute hepatitis E are relatively rare. The case report describes mononeuropatia multiplex with aseptic meningitis in a 52‑year‑old immunocompetent man. Viral hepatitis E was confirmed serologically and by polymerase chain reaction from the blood and cerebrospinal fluid (genotype 3f). Symptomatic treatment was given. Residual neurological deficit persisted six months after the onset of the disease. Diagnostic of hepatitis E should be considered in patients with concurrent neurological symptoms and liver cytolysis. Key words: hepatitis E – mononeuropatia multiplex The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE “uniform requirements” for biomedical papers., and L. Petroušová, L. Rožnovský, J. Mrázek, A. Kloudová, P. Vašíčková, I. Woznicová
Dideoxynucleotide DNA sequencing is one of the principal procedures in molecular biology. Loss of an initial part of nucleotides behind the 3' end of the sequencing primer limits the readability of sequenced amplicons. We present a method which extends the readability by using sequencing primers modified by polyadenylated tails attached to their 5' ends. Performing a polymerase chain reaction, we amplified eight amplicons of six human genes (AMELX, APOE, HFE, MBL2, SERPINA1 and TGFB1) ranging from 106 bp to 680 bp. Polyadenylation of the sequencing primers minimized the loss of bases in all amplicons. Complete sequences of shorter products (AMELX 106 bp, SERPINA1 121 bp, HFE 208 bp, APOE 244 bp, MBL2 317 bp) were obtained. In addition, in the case of TGFB1 products (366 bp, 432 bp, and 680 bp, respectively), the lengths of sequencing readings were significantly longer if adenylated primers were used. Thus, single strand dideoxynucleotide sequencing with adenylated primers enables complete or near complete readability of short PCR amplicons. and M. Beránek, M. Drastíková, J. Petera
