Several genotypes are identified as susceptibility genes for KD, but none is known in the Iranian population. Objectives: Due to the racial differences in the frequency and significance of the identified genes, we aimed to investigate the 8p22-23-rs2254546 genotypes in a sample of Iranian children and their association with aneurysm and resistance to treatment. Methods: In this prospective cross-sectional study, 100 children with KD as the sample group were compared with 100 matched unrelated healthy Iranian children with no history of KD or immune-related disease. The control subjects were ethnically recruited from the same hospital at the time of a routine physical examination. The 8p22-23-rs2254546 genotypes were analyzed using the polymerase chain reaction (PCR) and direct sequencing techniques, and the frequency of the three genotypes (GA, AA, and GG) was reported. Finally, the frequency of aneurysm and IVIG resistance was reported, and their associations with 8p22-23-rs2254546 genotypes were tested by SPSS software. Results: Of 100 patients with a mean age of 1.9 ± 1.7 (0.1 - 10.2) years, 57% were boys and 43% were girls. Of them, 62% had GG, 30% GA, and 8% AA genotypes. Besides, 21% of the studied patients were resistant to IVIG, and 19% had aneurysm, but resistance to IVIG and aneurysm was not associated with GG and GA genotypes of 8p22-23-rs2254546 (P = 0.29 and 0.88, respectively). Conclusions: The majority of the children with KD were shown to have this genetic susceptibility, which shows the importance of the 8p22-23-rs2254546 genotype in Iranian children. However, this genotype was not associated with the risk of resistance to IVIG and aneurysm.","PeriodicalId":44261,"journal":{"name":"Archives of Pediatric Infectious Diseases","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47444517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A retrospective analysis was conducted on case records, as well as patient data from all admissions to the PICU of Mofid Children’s Hospital, Tehran, from October 2017 to February 2018. Employing an android calculator application, the PIM-3 score was estimated early within the first PICU admission. Then, the PIM-3 score and mortality rate were analyzed using the Mann-Whitney U test. In addition, calibration and discrimination were assessed by the Hosmer-Lemeshow goodness-of-fit test and a receiver operating characteristic curve method, respectively. Finally, the Standardized Mortality Ratio (SMR) was calculated. Results: In this study, 365 young infants, ranging from 10 to 29-months-old, were included. The overall mortality rate was 10.4%. Further, the patients’ PIM-3 scores ranged from 0.06% to 2.37% (95% confidence interval), with a mean of 1.45% (4.16% in non-survivors and 1.14% in survivors). The SMR was estimated at 7.18, demonstrating the underprediction of the death rate. The AUC of 0.714 (95% CI: 0.626 to 0.801) demonstrated a fair to good discrimination power of PIM-3 as an international standard risk-adjusted mortality indicator. Moreover, this score underpredicted the risk of mortality in young infants admitted to our ICU in 2017. Generally, the prediction was weak among low-risk patients. Therefore, the Pediatric Index of Mortality-3 score has the potential to be implemented in our PICU by modifying the expected probability of death by multiplying the original PIM-3 score by 7.12.","PeriodicalId":44261,"journal":{"name":"Archives of Pediatric Infectious Diseases","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48441557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they cannot discriminate between latent tuberculosis infection (LTBI) and active tuberculosis (TB). Some recent studies suggested that interleukin-2 (IL-2) response to M. tuberculosis could be utilized as a potential biomarker to discriminate active disease from LTBI. Objectives: The current study aimed at evaluating the potential role of IL-2 to detect both active TB and LTBI among household contacts of patients with pulmonary TB in two TB-endemic regions of Iran. Methods: A total of 650 household contacts of patients with TB were invited to participate in the current study. All subjects were diagnosed on extensive clinical evaluation of active TB and LTBI based on clinical manifestations and laboratory findings. The IGRA test was performed using QuantiFERON®-TB Gold Plus. The serum level of IL-2 was measured using the ELISA Development Kit. Results: A total of 237 household contacts entered the final analysis, including 132 patients with LTBI and three with active TB. In addition, 14 subjects were included as TB controls and 102 as TB-uninfected controls. The serum level of IL-2 was significantly higher in active TB and LTBI patients than TB-uninfected controls. The ROC curve was plotted between active TB and LTBI, revealing that the cutoff point of 25.5 pg/mL identifies the active form with 88.24% sensitivity and 36.36% specificity. Conclusions: The current study indicated that the IL-2 assay could not discriminate between active TB and LTBI with acceptable sensitivity.","PeriodicalId":44261,"journal":{"name":"Archives of Pediatric Infectious Diseases","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46869558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: We aimed to evaluate the epidemiology of NIs and associated factors. Methods: From March 2017 to September 2018, all the neonates who were admitted to the NICUs of Bahrami Children’s Hospital were enrolled. Nosocomial infections were identified based on the definition of CDC-NNIS. Demographic, clinical, and laboratory data of the patients were extracted from the medical records. Results: A total of 979 neonates were admitted to the NICU, of whom 60 were diagnosed with NI. The incidence of NI was 6.1 per 100 hospitalized patients. The most prevalent NI was bloodstream infection (30%), followed by pneumonia (21.7%). The most frequent presentations were respiratory distress (31.7%) and poor feeding (26.7%). Major pathogens were Gram-positive bacteria such as Staphylococcus aureus (25.7%) and coagulase-negative staphylococci (25.7%). The mean hospital stay was 25.2 ± 20.89 days. The mortality rate of patients with NI was 16.7%. The factors associated with an increased risk of mortality among patients with NI were a lack of ventilation support, low birth weight, and WBCs with an abnormal range. Conclusions: The results of the present study showed that the incidence of NI was high, and the cultures collected from body fluids had a particular role in the diagnosis and treatment of NI. Standard infection control practices should be applied to reduce the incidence of NI and subsequent morbidity and mortality.","PeriodicalId":44261,"journal":{"name":"Archives of Pediatric Infectious Diseases","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42574928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it mostly affects adults, children of all ages, including neonates, can become ill with Covid-19, as well. The real prevalence rate of coronavirus disease 2019 (COVID-19) in children is unknown. However, the severity of symptoms in children and neonates is less than in adults. Regarding the new presentation of this disease, the current study has reported a case series of COVID-19 in neonates. Case Presentation: In this article, 10 neonates with COVID- 19 admitted to our neonatal intensive care units are reported. All reported neonates had general suspicious symptoms of COVID- 19 with positive results for SARS-CoV-2 assessed by polymerase chain reaction (PCR) from the nasopharynx area or nose of the patients. All neonates, except for two of them, were term neonates. One case had open-heart surgery for congenital heart disease (transposition of the great arteries (TGA)). The patients aged 22 days on admission. The most frequent symptom was fever. Severe respiratory symptoms were reported in two cases. Also, abnormal radiologic findings in the chest x-ray were detected in two cases. Regarding the lack of significant respiratory symptoms in most of the patients, the lung computed tomography (CT) scan was taken just from one neonate. Leukopenia (WBC < 5000/mm3) was detected in one case, with no lymphopenia in all neonates. The positive C-reactive protein test was not found in all cases. No patient was treated by special anti-viral agents for COVID-19, and usual antibiotic treatment for neonatal sepsis was administered for all cases. All patients, except for one, survived with no significant sequela of the disease. Conclusions: This study demonstrated that clinical manifestations, as well as laboratory and radiologic findings of COVID-19, are milder in neonates than in the older ages. Hence, it can be argued that the prognosis of COVID-19 in the neonatal period is generally good.","PeriodicalId":44261,"journal":{"name":"Archives of Pediatric Infectious Diseases","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44933271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: leprevention of mother-to-child transmission (PMTCT) program were enrolled in this study to compare two different diagnostic methods. After the extraction of viral RNA of plasma and genomic DNA of PBMC specimens, HIV-1 RNA and proviral DNA was tested by amplification of the long terminal repeat (LTR) region of HIV-1 using real-time PCR. Results: Out of 73 evaluated infants, 41 infants (56.2%) were male. The average age of the mothers with HIV-1 infection was 30.7 ± 5.2 (range: 19–47) years. The results revealed that none of the infants were infected with HIV-1, and also all were negative for HIV-1 genomic RNA in plasma specimen and proviral DNA of HIV-1 in PMBC samples. During the present study, 20 infants born to HIV-1 positive mothers who were not included in the PMTCT project were accidentally identified. Four infants (20%) out of these 20 infants were infected with HIV, all were infected with CRF35-AD of HIV, and none carried variants with surveillance drug-resistant mutations.

This study aimed to describe the cardiac manifestations of children diagnosed with MIS-C. Evidence Acquisition: This narrative review was conducted by searching the PubMed, Scopus, and Google Scholar databases to review MIS-C cardiac manifestations up to September 30, 2020. The demographic features, past medical history, clinical signs and symptoms, cardiac involvement, and the type of COVID-19 diagnosis confirmation were extracted. Results: In many children, MIS-C seems to be a post-infectious complication of the COVID-19 infection. This syndrome affects multiple organs and has various clinical manifestations mimicking Kawasaki disease. Patients frequently present with persistent fever, kidney injury, gastrointestinal (GI) problems, neurologic symptoms, mucosal changes, conjunctivitis, and cardiac involvement. Children with MIS are more likely to present with hypotension, shock, and cardiac dysfunction, rather than coronary artery abnormalities and arrhythmia. Children with MIS need close observation; some need to be hospitalized, and a few may need a Pediatric Intensive Care Unit (PICU) admission. Treatment currently includes anticoagulants, IV immunoglobulin, and anti-inflammatory drugs. Conclusions: As a novel syndrome associated with SARS-CoV-2 infection, MIS-C is potentially lethal. Cardiac manifestations, including coronary and myocardial involvement, are common and should be carefully identified. With prompt diagnosis and proper treatment, most children will survive, but the outcomes of the disease are unknown, so long-term follow-ups are required.","PeriodicalId":44261,"journal":{"name":"Archives of Pediatric Infectious Diseases","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45071267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One important action for a successful ASP is the implementation of an antimicrobial policy restriction. Objective: The study analyzed the quality of target-antimicrobial requisitions after the introduction of an antimicrobial policy restriction for children. Methods: We conducted a retrospective study in a neonatal intensive care unit (NICU) and three pediatric intensive care units (PICUs). An ASP was implemented in October 2016, and 14 target antimicrobials were selected to be prescribed after pre-approval by a pediatric infectious disease specialist. All requisitions were analyzed according to indication, antimicrobial type, dose, duration, and collection of cultures before administration. There were no exclusion criteria for requisition analysis. Results: Between October 2016 and December 2017, 1,173 patients were admitted to the units with 120 requisitions of target antimicrobials. Sepsis (43/120; 35.8%) was the most common indication, followed by respiratory infections (23/120; 19.2%) and infections in two or more sites (11/120; 9.2%). The most common target antimicrobials requested were meropenem (68/120; 56.7%), amphotericin B lipid formulations (12/120; 10%), teicoplanin (11/120; 9.2%), and linezolid (11/120; 9.2%). In 98 (81.7%) cases, previous cultures before antimicrobial administration were collected. An infectious agent was detected in 52 of the 98 cultures (53.1%), and Gram-negative and Gram-positive bacteria represented 50% and 26.9% of all positive samples, respectively. Besides, 111 (92.5%) requisitions were approved. In five refused requisitions, a narrow-spectrum antimicrobial was prescribed after further discussion; four were refused due to lack of information, and in one case, the de-escalation of the antimicrobial was possible. No mistake regarding dosage and duration was detected. Conclusions: We found a high-quality rate of target antimicrobial requisition.
