Neonatal necrotizing enterocolitis due to COVID-19. A case report.

Digestive symptoms have been reported in an important proportion of children with COVID-19, and the clinical expression of critical patients with COVID-19 is thought to result from progressive increase of inflammation and an unusual trend of hypercoagulation. We report a newborn received with abdominal distension, green vomiting and imaging suggestive for enterocolitis. He had a close contact with COVID-19 and the PCR for SARS-CoV-2 came back positive. Despite the supportive measures, his condition deteriorated and a surgery was decided. The surgical exploration found an ischemic bowel. The therapeutic measures were ineffective as the child passed away a few hours after surgery despite the resuscitation treatment performed. The confirmed enterocolitis happening within the period of acute infection by SARS-CoV-2, the NEC was likely a manifestation of COVID-19.

Hepatitis C virus infection in hemodialysis patients in Sudan: two centers' report.

Prevalence of HCV seropositivity among the hemodialysis population in Sudan is estimated to be around 34%. We undertook a cross sectional study in two major HD centers in Khartoum, Sudan for the prevalence of HCV seropositivity among the hemodialysis patients, during January to March 2005. Testing for HCV antibodies was performed using 3rd generation enzyme linked immunoadsorption assay (ELISA). A total of 236 patients were included in the study: 218 adults and 18 children. The mean age was 43.6 +/- 15.6 years, and the majority was males: 71.6%. The cause of renal failure was unknown in 168 patients (71.2%). The mean HD duration was 36.6 +/- 35.1 months. Prevalence of HCV seropositivity was 23.7%. Among 170 patients who were previously HCV seronegative, 30 (17.1%) seroconverted to positive in one year (estimated incidence: 63 new cases per year). HCV seropositivity was associated with longer duration of dialysis (p < 0.00001), previous surgery (p= 0.026), age of over 30 and years (p = 0.008), and dialysis in multiple centers (p= 0.005). We conclude that although HCV seropositivity in our study was lower than previously reported, it was still high among HD patients in Sudan. Nosocomial transmission of HCV among hemodialysis patients is a contributing factor.
