SUMMARYIn April 2005, an outbreak of Chikungunya fever occurred on the island of Réunion in the Indian Ocean. During winter 2005, six patients developed meningoencephalitis and acute hepatitis due to Chikungunya virus. Our objectives were to determine the incidence and mortality of atypical Chikungunya viral infections and to identify risk factors for severe disease. A hospital-based surveillance system was established to collect data on atypical Chikungunya cases. Case reports, medical records and laboratory results were reviewed and analysed. We defined an atypical case as one in which a patient with laboratory-confirmed Chikungunya virus infection developed symptoms other than fever and arthralgia. We defined a severe atypical case as one which required maintenance of at least one vital function. We recorded 610 atypical cases of Chikungunya fever: 222 were severe cases, 65 affected patients died. Five hundred and forty-six cases had underlying medical conditions (of which 226 suffered from cardiovascular, 147 from neurological and 150 from respiratory disorders). Clinical features that had never been associated with Chikungunya fever were recorded, such as bullous dermatosis, pneumonia, and diabetes mellitus. Hypertension, and underlying respiratory or cardiological conditions were independent risk factors for disease severity. The overall mortality rate was 10·6% and it increased with age. This is the first time that severe cases and deaths due to Chikungunya fever have been documented. The information presented in this article may assist clinicians in identifying the disease, selecting the treatment strategy, and anticipating the course of illness.

There is a scarcity of data regarding coronavirus disease 2019 (COVID-19) infection in children from southeast and south Asia. This study aims to identify risk factors for severe COVID-19 disease among children in the region. This is an observational study of children with COVID-19 infection in hospitals contributing data to the Pediatric Acute and Critical Care COVID-19 Registry of Asia. Laboratory-confirmed COVID-19 cases were included in this registry. The primary outcome was severity of COVID-19 infection as defined by the World Health Organization (WHO) (mild, moderate, severe, or critical). Epidemiology, clinical and laboratory features, and outcomes of children with COVID-19 are described. Univariate and multivariable logistic regression models were used to identify risk factors for severe/critical disease. A total of 260 COVID-19 cases from eight hospitals across seven countries (China, Japan, Singapore, Malaysia, Indonesia, India, and Pakistan) were included. The common clinical manifestations were similar across countries: fever (64%), cough (39%), and coryza (23%). Approximately 40% of children were asymptomatic, and overall mortality was 2.3%, with all deaths reported from India and Pakistan. Using the multivariable model, the infant age group, presence of comorbidities, and cough on presentation were associated with severe/critical COVID-19. This epidemiological study of pediatric COVID-19 infection demonstrated similar clinical presentations of COVID-19 in children across Asia. Risk factors for severe disease in children were age younger than 12 months, presence of comorbidities, and cough at presentation. Further studies are needed to determine whether differences in mortality are the result of genetic factors, cultural practices, or environmental exposures.

Neonatal sepsis is a systemic disease caused by bacterial organisms, viral infections, or fungus that causes hemodynamic abnormalities and other clinical symptoms resulting in severe complications and may progress into mortality. Parturition can be used to diagnose organisms caused by the premature onset of sepsis in some cases, but only after an average of three days of life. Clinical manifestations of infection may also diagnose the organisms caused by the early onset of sepsis. Late sepsis can refer to any incident of sepsis from delivery to discharge in high-risk newborns, and the majority of them have been hospitalized for a lengthy period. Late-onset Guillain-Barré syndrome infections generally refer to the infections that occur between one week and up to three months post-labor. The precise load fraction for newborn sepsis varies by context, with differing load estimations between nations with varying lead levels. With the diversity of treatments utilized, explaining the degree of obstetric palsy is crucial and complicated. When comparing birthing sepsis rates, it is critical to understand if a tiny figure represents a total birth rate or another rate, such as a hospital admission number. As stated, it is critical to evaluate if population estimates based on the numbers of neonatal sepsis episodes have been recorded. This article aims to review the literature regarding neonatal sepsis from different aspects including, the etiology, risk factors, and different types and onset of neonatal sepsis.

Introduction Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary microangiopathy leading to recurrent strokes and vascular dementia in young and middleaged patients. The diagnosis of CADASIL is based on typical clinical presentation and characteristic magnetic resonance imaging (MRI) changes, and has to be confirmed by biopsy of the sural nerve, muscle and skin, as well as by genetic analysis. Mutations within the Notch3 gene were identified as the underlying genetic defect in CADASIL. Case Outline The clinical manifestations of the first presented patient with migraine from the age of thirteen, stroke without vascular risk factors and stepwise progression of vascular dementia comprising the typical clinical picture of CADASIL, were confirmed after seven years with pathological verification. The second presented case did not satisfy the clinical criteria for CADASIL. His stroke was considered to be related with vascular risk factors - diabetes mellitus and hypertension. The aetiological diagnosis was established only when his brother without vascular risk factors presented with similar clinical manifestations. Conclusion Until the development of the new neuroimaging techniques like MRI, pathologic and genetic analysis, CADASIL was considered as a rare disorder. However, the increasing number of CADASIL families has been identified throughout the world showing that this entity is usually underdiagnosed. This article presents three patients from two Serbian families with clinical suspicion of CADASIL verified by pathologic examination. .

Pancreatic cancer is one of the most aggressive malignant neoplastic diseases. The incidence and mortality rates of this disease vary depending on geographical area, which might be explained by the different exposure to risk factors. To improve the prognosis of patients with pancreatic cancer, different approaches are needed for an earlier diagnosis. Identification of risk factors and implementation of screening strategies are essential for a better prognosis. Currently, the risk factors for pancreatic cancer fall into two broad categories, namely extrinsic and intrinsic factors. Extrinsic factors include alcohol consumption, smoking, a diet rich in saturated fats, and viral infections such as chronic infection with hepatitis B and C viruses. The pathophysiological mechanisms explaining how these hepatotropic viruses contribute to the development of pancreatic cancer are not fully elucidated. The common origin of hepatocytes and pancreatic cells in the multipotent endodermal cells, the common origin of the blood vessels and biliary ducts of the pancreas and the liver, or chronic inflammatory changes may be involved in this interaction. A careful monitoring of patients with viral liver infections may contribute to the early diagnosis of pancreatic cancer and improve the prognosis of these patients.

Background:Chikungunya virus (CHIKV) is a mosquito-borne alphavirus that circulates predominantly in tropical and subtropical regions, potentially affecting over 1 billion people. Recently, an outbreak began in the western hemisphere and has resulted in over 1.8 million reported suspected cases. Infection often results in severe fever, rash and debilitating polyarthralgia lasting weeks to months. Additionally, the current literature reports that CHIKV can result in a severe chronic arthralgia and/or arthritis that can last months to years following the initial infection.Objective:The purpose of this review is to evaluate the literature and summarize the current state of knowledge regarding CHIKV-associated disease, including clinical presentation, diagnosis, risk factors for development of severe disease, treatment, and pathogenesis in human patients. Additionally, recommendations are presented regarding avenues for clinical research to help further elucidate the pathogenesis of joint disease associated with CHIKV infection.Conclusion:While there is an association between initial CHIKV infection and acute disease, a causal relationship with development of chronic arthralgia has not been established at this time. Potential causes of chronic CHIKV-induced arthritis have been postulated, including viral persistence, induction of autoimmune disease, and exacerbation of pre-existing joint disease. While there are numerous reports of chronic CHIKV-associated arthralgia and/or arthritis, there is currently no evidence of a definitive link between initial infection and development of chronic disease. Additional, prospective clinical research on CHIKV-associated disease is necessary to further determine the potential role of virus and development of chronic joint disease.

AbstractInfections with dengue virus (DENV), West Nile virus (WNV) and Zika virus (ZIKV) usually present similar mild symptoms at early stages, and most infections (~80%) are asymptomatic. However, these infections may progress to severe disease with different clinical manifestations. In this study we attempted to identify unique characteristics for each infection at the presymptomatic/asymptomatic stage of infection and compared levels of soluble immune markers that have been shown to be altered during clinical course of these viral infections. Levels of soluble markers were determined by Luminex-based assays or by ELISA in plasma samples from asymptomatic blood donors who were reactive for RNA from DENV (n = 71), WNV (n = 52) or ZIKV (n = 44), and a control or non-infected (NI) group (n = 22). Results showed that even in the absence of symptoms, increased interleukin (IL) levels of IL-12, IL-17, IL-10, IL-5, CXCL9, E-Selectin and ST2/IL-1R4; and decreased levels of IL-13 and CD40 were found in all flavivirus group samples, compared to those from NI donors. DENV-infected donors demonstrated variation in expression of IL-1ra and IL-2; WNV-infected donors demonstrated variation in expression of IL-1ra, P-Selectin, IL-4 and IL-5; ZIKV-infected donors demonstrated variation in expression of IL-1ra, P-Selectin, IL-4, RANK-L, CD40L and C3a. The findings suggest that, even in the presymptomatic/asymptomatic phase of the infection, different immunomodulation profiles were associated with DENV, WNV and ZIKV infections.

The purpose of this paper is to review clinical studies on hypophosphatemia in pediatric intensive care unit patients with a view to verifying prevalence and risk factors associated with this disorder. We searched the computerized bibliographic databases Medline, Embase, Cochrane Library, and LILACS to identify eligible studies. Search terms included critically ill, pediatric intensive care, trauma, sepsis, infectious diseases, malnutrition, inflammatory response, surgery, starvation, respiratory failure, diuretic, steroid, antiacid therapy, mechanical ventilation. The search period covered those clinical trials published from January 1990 to January 2004. Studies concerning endocrinological disorders, genetic syndromes, rickets, renal diseases, anorexia nervosa, alcohol abuse, and prematurity were not included in this review. Out of 27 studies retrieved, only 8 involved pediatric patients, and most of these were case reports. One clinical trial and one retrospective study were identified. The prevalence of hypophosphatemia exceeded 50%. The commonly associated factors in most patients with hypophosphatemia were refeeding syndrome, malnutrition, sepsis, trauma, and diuretic and steroid therapy. Given the high prevalence, clinical manifestations, and multiple risk factors, the early identification of this disorder in critically ill children is crucial for adequate replacement therapy and also to avoid complications.

Abstract Background There is limited data on outcomes of SARS-CoV-2 infection among infants (< 1 year of age). In the absence of any approved vaccines for infants, understanding the risk factors for hospitalization and severe disease from COVID-19 in this age group will help inform clinical management and targeted public health interventions. The objective of this study was to describe the clinical manifestations, disease severity, and risk factors for hospitalization among infants with SARS-CoV-2 infection in Canada. Methods This is a nationwide prospective observational study using the infrastructure of the Canadian Paediatric Surveillance Program. All cases of infants aged < 1 year of age with microbiologically confirmed SARS-CoV-2 infection were reported from April 8th 2020 to May 11th 2021, and classified by disease severity, and primary cause of hospitalization. Logistic regression was performed to identify risk factors for hospitalization and severe disease. Results A total of 393 cases were reported, including 229 (58.3%) non-hospitalized and 164 (41.7%) hospitalized infants. The most common symptoms included fever (63.4%), runny nose (45.0%), cough (35.1%) and decreased oral intake (24.9%). Significant risk factors for hospitalization included younger age and presence of comorbid conditions (excluding prematurity), as shown in the Table. Among hospitalized infants, 108 (65.9%) were admitted because of COVID-19-related illness, and 52 (31.7%) were admitted for reasons other than COVID-19. A total of 31 (7.9%) infants developed severe or critical disease. Risk factors for severe disease included prematurity and younger age (Table). Conclusion We describe one of the largest cohort of infants with SARS-CoV-2 infection. Severe disease in this age group is uncommon, with younger age and prematurity being significant risk factors for severe COVID-19.

IntroductionRapid, robust and continually updated evidence synthesis is required to inform management of COVID-19 in pregnant and postpartum women and to keep pace with the emerging evidence during the pandemic.Methods and analysisWe plan to undertake a living systematic review to assess the prevalence, clinical manifestations, risk factors, rates of maternal and perinatal complications, potential for mother-to-child transmission, accuracy of diagnostic tests and effectiveness of treatment for COVID-19 in pregnant and postpartum women (including after miscarriage or abortion). We will search Medline, Embase, WHO COVID-19 database, preprint servers, the China National Knowledge Infrastructure system and Wanfang databases from 1 December 2019. We will supplement our search with studies mapped by Cochrane Fertility and Gynaecology group, Evidence for Policy and Practice Information and Co-ordinating Centre (EPPI-Centre), COVID-19 study repositories, reference lists and social media blogs. The search will be updated every week and not be restricted by language. We will include observational cohort (≥10 participants) and randomised studies reporting on prevalence of COVID-19 in pregnant and postpartum women, the rates of clinical manifestations and outcomes, risk factors in pregnant and postpartum women alone or in comparison with non-pregnant women with COVID-19 or pregnant women without COVID-19 and studies on tests and treatments for COVID-19. We will additionally include case reports and series with evidence on mother-to-child transmission of SARS-CoV-2 in utero, intrapartum or postpartum. We will appraise the quality of the included studies using appropriate tools to assess the risk of bias. At least two independent reviewers will undertake study selection, quality assessment and data extraction every 2 weeks. We will synthesise the findings using quantitative random effects meta-analysis and report OR or proportions with 95% CIs and prediction intervals. Case reports and series will be reported as qualitative narrative synthesis. Heterogeneity will be reported as I2 and τ2 statistics.Ethics and disseminationEthical approval is not required as this is a synthesis of primary data. Regular updates of the results will be published on a dedicated website (https://www.birmingham.ac.uk/research/who-collaborating-centre/pregcov/index.aspx) and disseminated through publications, social media and webinars.PROSPERO registration numberCRD42020178076.

Data on clinical manifestations of COVID-19 in immunocompromised patients in Russia is lacking, which prompted us to conduct a study to investigate clinical manifestations, risk factors, and outcomes of SARS-CoV-2 infection in children with oncological and hematological diseases treated at the D. Rogachev NMRCPHOI (Center). In this retrospective-prospective, nonrandomized, non-interventional study we enrolled children under 18 years with cancer, hematologic malignancies, and primary immunodeficiencies (PIDs) who underwent treatment at the Center from April 2020 to October 2021. COVID-19 cases were confirmed by polymerase chain reaction testing and classified as asymptomatic, mild, moderate, severe and critical. The study was approved by the Independent Ethics Committee and the Scientific Council of the Center. The study included 89 patients with a median age of 9.7 years and almost equal gender distribution (the male-to-female ratio was 1.1:1). Most patients (74%) were infected in a family claster. The main underlying diseases were: hemoblastoses (43.8%), solid tumors (33.7%), PIDs (14.6%). The most common clinical symptoms were fever (29%) and respiratory symptoms (47%). In 79% of cases, patients were asymptomatic or had mild symptoms; 21% of patients had moderate and severe disease (16% and 5%, accordingly). Risk factors associated with severe COVID-19 included lymphopenia (p < 0.001) and hematopoietic stem cell transplantation (HSCT) (p = 0.002). Full recovery was documented in 84% of the patients, 16% died, however COVID-attributed mortality was 5.5%. The highest mortality was in patients with moderate/severe COVID-19 (47% vs 7%, p < 0.001), in those with progression/ relapse of the underlying disease (36.3% vs 6%, p = 0.02), in children who had received specific therapy within a year before the SARS-CoV-2 diagnosis (21% vs 0%, p = 0.02), among HSCT recipients (31.6% vs 12.1%, p = 0.02), and patients with concomitant infections (33% vs 9.2%, p < 0.01). Factors associated with poor prognosis were moderate or severe COVID-19, relapse/ progression of the underlying disease, specific treatment (HSCT in particular) within 1 year before the SARS-CoV-2 diagnosis, concomitant infections, and lymphopenia. Data obtained in this study can help physicians with management decisions at this population of patients.
