RESUMO

BACKGROUND: Despite the worldwide spread of Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2), information about the epidemiological and clinical patterns of this infection is still largely unknown in children. In addition, the prevalence of this disease is still very high in some parts of the world, including Iran. Thus, this study aims to evaluate the epidemiological features, laboratory and imaging findings, and the type of treatments in children with novel coronavirus 2019 (COVID-19). METHOD: This study is conducted from March 2020-March 2021 by using the medical records of hospitalized confirmed COVID-19 children younger than 18 years in five cities of Iran: Tehran, Ahwaz, Isfahan, Bandar-Abbas, and Khorramabad. In addition to demographic and epidemiological data, we also studied clinical signs and treatments. RESULTS: In total 278 confirmed COVID-19 children, the average age was 5.3 years, and 59.4%were boys. A total of 37.8% had an underlying disease, in which the most common was a malignancy. The most common symptoms were fever and cough. In this group of pediatrics, some abnormal laboratory findings have been seen. GGO (Ground-Glass Opacity) had been diagnosed in 58.6% of children. 3.6% needed oxygen therapy with ventilators, and 83.09% had received antibiotic treatments with the majority of ceftriaxone. Also, 10% had got steroids. In this study, the mortality rate was 4.3%. CONCLUSION: In this study, most of the children who died had an underlying disease, so timely care and action is important in them. Most children admitted to our study received antibiotics and were prescribed antivirals and steroids for a smaller number. Also, a small number of children received oxygen therapy, most of whom were in the age group of 1 to 5 years.

RESUMO

Background: Recent studies indicate an increased incidence of pertussis disease in recent years. The aim of this study was to evaluate the efficacy of the acellular vaccine for children (as a replacement of current whole cell vaccine in the Expanded Program on Immunization) and for high-risk adults in Iran through updating current best available evidence. Methods: We performed a systematic literature review in relevant databases we focused on previously published systematic reviews to select those that address our questions. The AMSTAR (assessing the methodological quality of systematic reviews) tool was used for screening available reviews. Then search in databases was done until Feb 2014 to update the evidence. We pooled results using meta-analysis methods by Stata statistical package. Results: Eleven systematic review articles were included in the initial evaluation. In the end, two systematic reviews on acellular vaccine booster doses and the acellular vaccine in children were selected as the baseline evidence. In the update phase, new clinical trials were screened, and the results were updated. Overall pooled estimate of relative efficacy of acellular to whole cell was 0.68 (95% CI, 0.55-0.81) for children immunization Pooled estimates for the efficacy of acellular versus placebo were 0.70 (95% CI, 0.60-0.80). Overall pooled estimate of efficacy of booster dose of acellular was 0.87(95% CI, 0.85-0.88) compared to placebo. In addition pooled estimate of acellular vaccine efficacy based on response to antigen was 0.78(95% CI, 0.64-0.93) in highrisk group. Conclusion: The results show higher performance and safety of the acellular vaccine in the prevention of pertussis in children versus the whole cell vaccine. Moreover, the efficacy of the acellular vaccine in high-risk adult groups is acceptable. This study provides evidence in favor of the introduction of an acellular vaccine to the national program of immunization. Studies on cost effectiveness and aspects of policy analysis are recommended.

RESUMO

Primary immunodeficiencies are a diverse group of rare genetic disorders, among which phagocytic dysfunction impairs neutrophil function in a wide range of inherited disorders. Due to the heterogeneity of the disorders a multidisciplinary approach is often required for early diagnosis and initiation of appropriate treatments. The aim of this study was to evaluate the imaging findings in children admitted with phagocytic primary immunodeficiencies. Thirty-five children who fulfilled the inclusion criteria for phagocytic dysfunction were enrolled in this study. The patients were under close observation and monitoring from January 2011 until data locking in December 2017. The diagnosis of phagocytic immunodeficiency was confirmed by the patient's clinical course, presentation features, and laboratory data.  Among the 35 patients studied, the most frequent condition was chronic granulomatous disease (CGD) (23 patients), followed by different types of neutropenia (8 patients) and Job's syndrome (4 patients). Mediastinal and hilar lymphadenopathies and consolidation were the most frequent presentations. There was a significant relationship between mediastinal/hilar lymphadenopathies and fungal infections. A meaningful relationship was also found between pulmonary nodules without halo signs in patients with concomitant tuberculosis and fungal infections. A significant correlation was found between CGD, pulmonary fibrotic changes, and mediastinal lymphadenopathies. The most frequent radiological manifestations in children included mediastinal and hilar consolidations. Physicians' awareness of the radiological and clinical manifestations of these inherited diseases may be helpful in the early diagnosis and timely initiation of specific prophylaxis measures to prevent infections and also to initiate hematopoietic stem cell transplantation as the curative management modality.

RESUMO

Introduction: Kawasaki disease(KD) is a vasculitis of childhood that tends to influence the coronary arteries. There is no national data about the prevalence of KD in Iran. This study aimed to perform a national registry in Iran for 13 years. Methods: In this retrospective study, the data for KD extracted from medical records of <19 year-old patients admitted to tertiary hospitals in Iran between 2007 and 2019 were recorded in the national KD registry system. Age, admission date, gender, location, and presence of KD criteria, laboratory and echocardiography findings, and treatment modalities were evaluated. Complete KD was considered if ≥4 clinical criteria of the KD existed and otherwise, incomplete KD was considered. Results: Data from 1,682 KD patients including 999(59.39%) boys and 683(40.61%) girls and male/female ratio of 1.46 were evaluated. The mean age was 3.08 ± 2.49 years and 1465(87%) were living in urban regions. The yearly incidence of the disease was between 2.62 to 3.03 from 2015 to 2019. The highest age-specific incidence was observed in children <1-year-old. Incomplete and resistant KD included 1,321(78.54%) and 9(0.54%) patients, respectively. Abnormal echocardiography was detected in 619(36.80%) patients. Leukocytosis, with dominancy of neutrophils, anemia, thrombocytosis and increased ESR and CRP were the most noticeable laboratory findings. No death due to KD disease was reported. Conclusion: Based on this study, most of the KD cases are presented with atypical presentation in Iran. So, increasing awareness of primary healthcare workers by educating and updating their data is very important in timely diagnosis and management of the disease.
