ABSTRACT
BACKGROUND: The World Health Organization has set a goal of hepatitis C virus (HCV) elimination by the year 2030. However, no regions in Japan have succeeded in eradicating HCV. Micro-elimination is an approach to attain hepatitis C eradication in which national eradication goals are applied to specific populations so that viral treatment and control efforts can move forward quickly and efficiently. In order to eradicate HCV from Japan, this study aims to achieve HCV micro-elimination in the town of Nagawa. METHODS AND DESIGN: The Nagawa Project is an ongoing, prospective, multiple-institution, observational study running from April 1, 2021, to March 31, 2024. All residents of Nagawa town, excluding those under 20 years of age, not consenting to the study, or unable to undergo health check-ups due to nursing care needs, will be included. If found to be HCV antibody-positive, the participant will be recommended to see a doctor in consideration of MAC-2 binding protein glycosylation isomer values. Then, the participant will undergo serum HCV RNA measurement with the real-time polymerase chain reaction by an attending physician. If the participant is HCV RNA-positive, he or she will be referred to a hepatologist for further evaluation. In the case of a definitive diagnosis of chronic hepatitis C, direct acting antiviral treatment will be initiated. Through this process, HCV will be systematically micro-eliminated from the region. DISCUSSION: The Nagawa Project will reveal the prevalence of chronic HCV in addition to the HCV eradication rate in Nagawa town towards achieving HCV micro-elimination. TRIAL REGISTRATION: This study is performed by Shinshu University School of Medicine and was registered as UMIN 000044114 on May 6, 2021.

We report two cases of fetofetal transfusion in monochorionic triamniotic triplet pregnancies. Case 1: At 23 weeks' gestation an amnioreduction was carried out. Three days later, the donor triplet died in utero. Immediately after that, a cardiotocogram of the triplet who had been thought to be unaffected by the fetofetal transfusion, showed a non-reassuring fetal status. Although cesarean section was carried out, none of the triplets survived. Case 2: At 24 weeks' gestation a woman was transferred to our center because of fetofetal transfusion in monochorionic triplets. Cesarean section was carried out. However, the recipient died on the 75th day after birth, and the others had neurological problems. Previous reports on fetofetal transfusion in triplets are very limited. The prognosis of this condition has been reported to be severe, irrespective of chorionicity, gestational age at delivery, maternal age, and parity. When managing a monochorionic or dichorionic triplet pregnancy, serial and careful ultrasound examination is mandatory to find early symptoms of this serious condition.
