Watch out for malaria: still a leading cause of child death worldwide

<p>Abstract</p> <p>Background</p> <p>Due to the efforts in malaria control promoted by the World Health Organization (WHO), the reported malaria burden is being reduced throughout the world. Nevertheless, malaria remains a leading cause of child death worldwide.</p> <p>Aims</p> <p>purpose of the paper is to summarize the main historical steps in fighting malaria, from the first descriptions to the last ones.</p> <p>Results</p> <p>a case of probable autochthonous malaria has been recently described in Italy, raising concern over the possibility of resurgence of malaria in countries previously interested by this disease. Moreover, both the constant threat of the parasite and vector mosquito developing resistance to medicines and insecticides, and the on-going climate change make the challenge of eradicating malaria really difficult. Therefore, malaria is still an actual disease, requiring adequate programs of surveillance, stronger health systems in poor countries, and efforts in order to develop new and effective tools in malaria control. WHO has definitely demonstrated the effects of "social determinants" on health. So, eradication strategies cannot be based only on a scientific background, because culture, politics, power, resources and wars have a profound impact on health and disease. These elements should be introduced in all the programs of malaria control.</p> <p>Conclusions</p> <p>malaria is still an actual disease with great public health implications, and the approaches for control and prevention should have the appropriate social and political context in addition to the science involved in order to save lives of children at risk.</p

Viral persistence in children infected with SARS-CoV-2: current evidence and future research strategies

In this Personal View, we discuss current knowledge on SARS-CoV-2 RNA or antigen persistence in children infected with SARS-CoV-2. Based on the evidence that the virus can persist in adults, we have done a literature review and analysed studies that looked for SARS-CoV-2 RNA or antigens in children undergoing autopsy, biopsy, or surgery for either death from COVID-19 or multisystem inflammatory syndrome, or assessments for long COVID-19 or other conditions. Our analysis suggests that in children, independent from disease severity, SARS-CoV-2 can spread systemically and persist for weeks to months. We discuss what is known about the biological effects of viral persistence for other viral infections and highlight new scenarios for clinical, pharmacological, and basic research exploration. Such an approach will improve the understanding and management of post-viral syndromes

Characteristics and predictors of Long Covid in children: a 3-year prospective cohort study

Background: Children can develop Long Covid, however long term outcomes and their predictors are poorly described in these patients. The primary aim is to describe characteristics and predictors of Long Covid in children assessed in-clinics up to 36 months post-SARS-CoV-2 infection, as well as investigate the role of vaccines in preventing Long Covid, risk of reinfections and development of autoimmune diseases. Methods: Children aged 0–18 years old with confirmed SARS-CoV-2 infection were invited for a prospective follow-up assessment at a peadiatric post-covid clinic in Rome, Italy, at serial intervals (3-, 6-, 12-, 18-, 24- and 36-months post-infection onset, between 01/02/2020 and 28/02/2024). Long Covid was defined as persistence of otherwise unexplained symptoms for at least three months after initial infection. Findings: 1319 patients were initially included, 1296 reached the 3 months follow-up or more. Of the patients who underwent multiple follow-ups, 23.2% (301), 169 (13.2%), 89 (7.9%), 67 (6.1%), 47 (7.1%) were diagnosed with Long Covid at 3-6-12-18-24 months, respectively For the primary outcome of Long Covid at three months, age &gt;12 years (P &lt; 0.001, OR 11.33, 95% CI 4.2; 15.15), comorbidities (P = 0.008, OR 1.83, 95% CI 1.06; 2.44), being infected with original variants (P &lt; 0.001, OR 4.77, 95% CI 2.46; 14.47), female sex (P &lt; 0.001, OR 1.62, 95% CI 1.02; 1.89) were statistically significant risk factors. Age &gt;12 years (P = 0.002, OR 9.37, 95% CI 1.58; 8.64), and infection with original (P = 0.012, OR 3.52, 95% CI 1.32; 8.64) and alfa (P &lt; 0.001, OR 4.09, 95% CI 2.01; 8.3) SARS-CoV-2 variants remained statistically significant risk factors for Long Covid duration for at least 18 months. Vaccination was associated with a lower risk of long covid at 3, 6 and 12 months for older children and a lower risk of reinfections. Being infected with the original SARS-CoV-2 variant was associated with a higher risk of new-onset autoimmune diseases ((P = 0.035, 95% CI 1.12; 2.4). One patient was diagnosed with Long Covid after a re-infection. Interpretation: This is the longest follow-up study of children with SARS-CoV-2 infection, showing a significant and long-lasting burden of Long Covid in the pediatric population. Our findings highlight the urgent need of investing in pediatric Long Covid in order to find effective diagnostic and therapeutic approaches, as well can inform preventive strategies in case of future pandemics.

COMPARISON OF THE CLINICAL AND LABORATORY FEATURES OF COVID AND INFLUENZA IN CHILDREN

Background and Objectives. Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2 and has a clinical presentation ranging from asymptomatic course to flu-like syndrome up to respiratory failure. Seasonal Influenza, due by the influenza viruses and very common in children, can cause symptoms similar to COVID-19. In order to identify clinical and laboratory characteristics that allow health-care workers to differentiate COVID-19 from Influenza, we performed a systematic review of the existing literature in the pediatric age. Methods.  The research was done via PubMed for articles published from March 2020 to October 2021, combining the MeSH words "COVID-19" and "Influenza" and "Children" and considering the suggestions of PRISMA Group. Results. The most frequently described symptoms were fever and cough in both groups. In most studies, high fever, cough, nasal congestion or rhinorrhea, vomiting and muscle pain were detected more frequently in the Influenza group. Regarding the value of laboratory tests, the results were mixed. Almost all studies reported significantly lower levels of C-reactive protein and procalcitonin in the COVID-19 group than in the Influenza group. In most manuscripts, COVID-19 had a milder course than Influenza. Conclusions. There are no symptoms characteristic of a single infectious agent, with flu-like disorders being the most common. In addition, laboratory tests do not help in the differential diagnosis but show a limited inflammatory response in COVID-19. This could explain the fewer complications compared to adulthood, with a less severe clinical course. Keywords: COVID-19; Influenza; children                  

Congenital syphilis in a two-month-old infant

This report describes a rare case of congenital syphilis in a two-month-old Romanian infant. Diagnosis was possible when the baby showed decrease in the left upper limb movements and a papular rash. Her father had been infected and transmitted the infection to the mother, who had two non-treponemal serological tests during pregnancy, both with negative results. Congenital syphilis was confirmed by serological tests and the newborn was successfully treated. A global overview on diagnosis and treatment of children with suspected congenital syphilis is presented

Risk factors for post-COVID-19 condition (Long Covid) in children: a prospective cohort study

Background: Adults and children can develop post-Covid-19 condition (PCC) (also referred to as Long Covid). However, existing evidence is scarce, partly due to a lack of a standardised case definition, short follow up duration, and heterogenous study designs, resulting in wide variation of reported outcomes. The primary aim of this study was to characterise risk factors for PCC and longitudinal rates of recovery in a cohort of children and young people using a standardised protocol. Methods: We performed a prospective “disease-based” cohort study between 01/02/2020 to 31/10/2022 including children aged 0–18 years old, with a previous diagnosis of Covid-19. Children with microbiologically confirmed SARS-CoV-2 infection, were invited for an in-clinic follow-up assessment at a paediatric post-covid clinic in Rome, Italy, at serial intervals (3-, 6-, 12- and 18-months post-onset). PCC was defined as persistence of otherwise unexplained symptoms for at least three months after initial infection. The statistical association between categorical variables was obtained by Chi-squared tests or Fisher's exact tests. Multivariable logistic regressions are presented using odds ratios (OR) and 95% confidence interval (CI). Survival analysis was conducted using the Kaplan–Meier method. Findings: 1243 children were included, median age: 7.5 (4–10.3) years old; 575 (46.3%) were females. Of these, 23% (294/1243) were diagnosed with PCC at three months post-onset. Among the study population, 143 patients remained symptomatic at six months, 38 at 12 months, and 15 at 18 months follow up evaluation. The following risk factors were associated with PCC: &gt;10 years of age (OR 1.23; 95% CI 1.18–1.28), comorbidities (OR 1.68; 95% CI 1.14–2.50), and hospitalisation during the acute phase (OR 4.80; 95%CI 1.91–12.1). Using multivariable logistic regression, compared to the Omicron variant, all other variants were significantly associated with PCC at 3 and 6 months. At least one dose of vaccine was associated with a reduced, but not statistically significant risk of developing PCC. Interpretation: In our study, acute-phase hospitalisation, pre-existing comorbidity, being infected with pre-Omicron variants and older age were associated with a higher risk of developing PCC. Most children recovered over time, but one-in-twenty of those with PCC at three months reported persistent symptoms 18 months post-Sars-CoV-2 infection. Omicron infection was associated with shorter recovery times. We did not find a strong protective effect of vaccination on PCC development. Although our cohort cannot be translated to all Italian children with PCC as more nationwide studies are needed, our findings highlight the need of new strategies to prevent and treat pediatric PCC are needed.
