The present study was carried out to investigate the nephroprotective effect of the ethanolic extract of Allium saralicum R.M. Fritsch (ASRMF) in mice. Thirty-five male mice were divided into five groups (n=7). Group 1 (positive control) received 1 mL/kg olive oil intraperitoneally (i.p.) and 0.5 mL distilled water orally; Group 2 (negative control) received CCl 4 (50% in olive oil, 1 mg/kg; i.p.); Groups 3, 4 and 5 received CCl 4 and 200, 800 and 1600 µg/kg of ASRMF extract, respectively. The renal volume and cortex in Groups 1 and 2 were increased by 55% and 62% (p≤0.001) following CCl 4 administration, respectively, and were improved after ASRMF administration. The volume of proximal convoluted tubules (PCTs), glomeruli, vessels and interstitial tissue increased 80%, 150%, 83% and 64% (p≤0.05), respectively, in CCl 4treated mice, and decreased significantly with 800 and 1600 µg/kg of ASRMF. The length of PCTs and vessels increased 51% and 45% and decreased (p≤0.05) with 200, 800 and 1600 µg/kg of ASRMF, respectively. CCl 4-treated mice lost 22.5% of glomeruli; the loss was inhibited significantly (p≤0.05) by ASRMF. Urea and creatinine concentrations were increased (p≤0.05) in CCl 4-induced nephrotoxicity as compared to the controls, whereas different doses of ASRMF restored the levels of these biomarkers compared to the negative controls. In conclusion, ASRMF has a potent nephroprotective property and can improve renal structural and serum biomarkers in CCl 4-induced nephrotoxicity in mice.
Urinary tract infection (UTI) is associated with increased health burden among paediatric patients. Vitamin D is known for its immunoregulatory effects, particularly antimicrobial activity. The aim of this study was to determine the relationship between vitamin D levels and UTIs in children referred to a hospital in Khorramabad, Iran. This case–control study was conducted on 258 children aged between 2 and 14 years; 44 children with UTI and 214 healthy children were enrolled. Patients were tested for UTI on the basis of signs and symptoms, and urine culture and analysis. Vitamin D levels were measured in children in both groups. According to the results, the two groups were significantly different in terms of sex (p 0.007). There was no significant difference between the mean vitamin D among the two groups. Vitamin D levels were not related to UTI by multivariate logistic regression. The relationship between the level of vitamin D and the incidence of UTI in children in accordance with age and sex had an odds ratio of 0.99, indicating that for a 1-unit increase in vitamin D, the odds of having a UTI decreased by 1, a correlation which was not statistically significant. According to the findings of this study, no significant correlation was found between UTI and vitamin D levels. However, the prevalence of UTI was higher in girls than boys.
Background The objectives of this study were to analyze the clinical features and laboratory profiles and risk factors associated with critical illness of children with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Methods One hundred and sixty‐six coronavirus disease 2019 (COVID‐19) Iranian pediatric patients were recruited through a collaborative research network between March and May 2020. Demographics, clinical, laboratory, and radiological results were obtained from patient files. Results Of 166 patients, 102 (61%) and 64 (39%) were males and females, respectively. Ninety‐six (57.8%) and 70 (42.2%), had moderate and severe conditions, respectively. Thirty (18%) of patients died. The common symptoms were fever (73%), cough (54%), and shortness of breath, headache decrease in neutrophil and platelet counts; increase values in lactate dehydrogenase, decrease in the blood pH and HCO3 were significantly associated with the disease severity. 54% and 56% of patients showed abnormal radiographic appearance in Chest X‐ray and in chest computed tomography scan, respectively. Sixty‐one (36.7%) of patients were referred to intensive care unit (ICU). The coexistence of comorbidity was the main factor associated with ICU admission, shock, arrhythmia, acute kidney injury, acute respiratory distress syndrome, acute cardiac injury, and death. Conclusions We describe a higher than previously recognized rate of COVID‐19 mortality in Iranian pediatric patients. Epidemiological factors, such as the relatively high case fatality rate in the country and the presence of underlying diseases were the main factors for the high death rate.
Inflammatory and infectious diseases are the major causes of morbidity and mortality. The identification of markers for the assessment of disease activity and response to treatment can improve long-term prognosis. The aim of this study was to evaluate platelet count, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) among children with inflammatory and infectious disease. This cross-sectional study was conducted in the paediatric immunology and infectious units of Shahid Madani Hospital of Khorramabad. One hundred fifty children, half boys and half girls, with diagnoses of infectious and inflammatory diseases were included in the study. Platelet count, ESR and CRP were measured at the time of hospitalization and thereafter (recovery phase). A questionnaire including demographic information, diagnosis and paraclinical data was completed. At the time of hospitalization, all 150 children had abnormal ESR, 110 (73.3%) had abnormal CRP and 12 (92%) had alterations in platelet count. At the time of discharge, one patient (0.7%) had normal ESR, 132 (88%) had normal CRP and 140 patients (93.3%) had normal platelet count. At the time of discharge, we found a significant difference between the levels of CRP and platelets in girls. This study showed that CRP level is useful during treatment follow-up. Changes in platelet count are likely to be more prevalent in girls.
Introduction: To date, little is known about the clinical features of pediatric COVID-19 patients admitted to intensive care units (ICUs). Objective: Herein, we aimed to describe the differences in demographic characteristics, laboratory findings, clinical presentations, and outcomes of Iranian pediatric COVID-19 patients admitted to ICU versus those in non-ICU settings. Methods: This multicenter investigation involved 15 general and pediatrics hospitals and included cases with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection based on positive real-time reverse transcription polymerase chain reaction (RT-PCR) admitted to these centers between March and May 2020, during the initial peak of the COVID-19 pandemic in Iran. Results: Overall, 166 patients were included, 61 (36.7%) of whom required ICU admission. The highest number of admitted cases to ICU were in the age group of 1–5 years old. Malignancy and heart diseases were the most frequent underlying conditions. Dyspnea was the major symptom for ICU-admitted patients. There were significant decreases in PH, HCO3 and base excess, as well as increases in creatinine, creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and potassium levels between ICU-admitted and non-ICU patients. Acute respiratory distress syndrome (ARDS), shock, and acute cardiac injury were the most common features among ICU-admitted patients. The mortality rate in the ICU-admitted patients was substantially higher than non-ICU cases (45.9% vs. 1.9%, respectively; p<0.001). Conclusions: Underlying diseases were the major risk factors for the increased ICU admissions and mortality rates in pediatric COVID-19 patients. There were few paraclinical parameters that could differentiate between pediatrics in terms of prognosis and serious outcomes of COVID-19. Healthcare providers should consider children as a high-risk group, especially those with underlying medical conditions.
