New Generation Rotavirus Vaccines

WOS: 000377695500006Rotavirus gastroenteritis (RVGE) is a vaccine-preventable disease that causes hospitalization and deaths due to severe gastroenteritis in developing countries. The World Health Organization (WHO) reported that 801000 children die annually due to gastroenteritis. Improvement in hygienic conditions is insufficient for preventing rotavirus gastroenteritis due to transmission via droplets and resistance to disinfectants; therefore, vaccination is the most effective method for prevention. At present, there are two licensed rotavirus vaccines, monovalent rotavirus vaccine (RV1, Rotarix, GlaxoSmithKline) and pentavalent rotavirus vaccine (RV5, RotaTeq, Merck). The WHO offered to integrate the rotavirus vaccine to the national vaccination programs of all countries worldwide since 2009. Current licensed vaccines have since demonstrated efficacy against severe gastroenteritis and hospitalization in developed countries. In countries with low income and high disease vaccination rate is low because of difficulties in vaccine supply and high cost of the vaccine and consideration about diminished efficacy of the other oral vaccines. Therefore, several groups are led to develop around the world, new rotavirus vaccines. In this review, we provide a summary of the new licensed vaccines with ongoing clinical trials and the locally licensed vaccines

Clinical Features of COVID-19 in Children

Sahbudak Bal, Zumrut/0000-0001-9189-8220WOS: 000533660200002In early December, pneumonia cases of unknown origin started to appear and, on the 7th of January 2020, these cases were declared to be caused by a novel beta-coronavirus according to viral genome sequencing on the 11th of February, 2020. Coronaviruses are enveloped, single strand RNA viruses that have been known to have the ability to mutate rapidly, alter tissue tropism and adjust to different epidemiological situations. As of the end of April 2020, 122,392 laboratory-confirmed cases of COVID-19 had been detected in Turkey, of whom 3,258 died. From the beginning of the COVID-19 epidemic, children seem to be less affected than adults. Therefore, there are limited data regarding the clinical features of COVID-19 in children. the majority of children with confirmed COVID-19 had a history of household contact. the most common symptoms were fever and cough. Previous data suggest that nearly half of patients are afebrile at the onset of the disease. Hospitalization and PICU admission rates for children were lower than for adults. However, PICU admission can be necessitated in children with severe disease. Infants, particularly under the age of 12 months, were more likely to develop severe disease. in children, milder and asymptomatic cases can be challenging and can play a role in transmission. in particular, clinicians should test those children who have a history of family cluster even though they are asymptomatic or present with mild symptoms

Infections in children with left ventricular assist device

Sahbudak Bal, Zumrut/0000-0001-9189-8220; Ozbaran, Mustafa/0000-0003-0259-0799WOS: 000559903300001PubMed: 32767830Background There are limited data about pediatric left ventricular assist device (VAD) infections in developing countries. This study aimed to investigate device postimplantation infectious complications and their pathogenic profile. Methods Data were analyzed from patient charts involving 27 patients with dilated cardiomyopathy who underwent left VAD implantation at a leading tertiary care center in Turkey. Results the study included 17 boys and ten girls with a median age of 12.22 years (range 17 months to 18 years). Nineteen patients were diagnosed with idiopathic, and three were diagnosed with familial dilated cardiomyopathy. Twenty-two out of 27 subjects (%81.48) developed 80 infection episodes in total. the most common type of left VAD-specific infection was the exit site of the driveline. Infected patients with left VAD had a significantly prolonged hospitalization compared with the patients without infection (P = .014). Infection-induced pediatric intensive care unit (ICU) admission was higher in patients with fungal infection(P = .023). Gram-positive staphylococci were the most commonly isolated bacterial pathogens, followed by Gram-negative bacteria. Five patients developed fungal infections. None of the fungal infection patients underwent transplantation(P = .035). Seven deaths occurred in our study group. All deaths were in the infected group. Mortality was associated with the presence of multidrug-resistant Gram-negative bacterial infections (P = .015), an increased number of infection episodes (P = .003), and hospitalization due to infection (P = .003). Conclusion Ventricular assist device-related infections were frequent among our study patients. the predominantly isolated agents were Gram-positive bacterial pathogens. However, the emergence of relatively high rate of Gram-negative bacterial and fungal infections was associated with mortality before the transplantation. Establishing local programs for surveillance data, controlling for infection rates, and antibiotic stewardship are essential to reduce mortality of VAD patients in developing countries

The Longest Infectious Virus Shedding in a Child Infected With the G614 Strain of SARS-CoV-2

COVID-19 spread globally and caused over 97 million cases with more than 2 million deaths. There is still ongoing discussion on the duration of infectious interval SARS-CoV-2 infection. Symptomatic children had longer virus shedding and there are some reports of prolonged infectious virus shedding in adults particularly patients having an immunocompromised status. A missense mutation, D614G, in the spike protein of SARSCoV-2, which has emerged as a predominant clade in Europe and is spreading worldwide that can result in higher viral loads in patients. Herein, we described the longest infectious virus shedding in a previously healthy child infected with SARS-CoV-2 expressing spike D614G substitution
