Résumé

Objective:To investigate the clinical characteristics of children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variants, and the impact factors of duration of cycle threshold (Ct) values turning to ≥35 detected by nucleotide test.Methods:Children aged 0 to 14 years with clinical symptoms of Omicron variants infection who admitted to designated hospital in Shanghai City (Renji Hospital, South Branch, Shanghai Jiao Tong University School of Medicine) from April 7 to June 2, 2022 were enrolled. The daily nasopharyngeal swab specimens were used for SARS-CoV-2 nucleic acid detecting by polymerase chain reaction and the results were expressed as Ct values. The T Ct≥ x was defined as from the symptom onset or first positive nucleic acid test results (the earlier data) to Ct≥ x of the open reading frame 1ab ( ORF1 ab) gene, which was the time duration from the initial to a specific Ct value.Clinical data were collected, including age, sex, vaccination and comorbidities.Cox model was performed to analyzed the impact factors of T Ct≥35. Results:A total of 871 pediatric cases with a median age of two years (ranging from one month to 14 years old) were included. Among them, 474 cases (54.4%) were male, and 89 cases (10.2%) had underlying diseases including congenital heart disease, solid tumors and epilepsy. There were 572(65.7%) mild cases, 298(34.2%) common cases, one (0.1%) severe case and no critical cases or deaths. The T Ct≥35 was 12(10, 14) days. Cox model indicated that compared to children aged one to 12 months, children aged 37 to 84 months and 85 to 168 months had shorter T Ct≥35 (hazard ratio ( HR)=1.55 and 1.84, respectively, both P<0.001). After adjusted with age, comparing to unvaccinated patients, patients with one or two shots vaccine had shorter T Ct≥35 (adjected hazard ratio (a HR)=1.49, P=0.011), and common patients had longer T Ct≥35 than mild patients (a HR=0.78, P=0.002), and patients with comorbidities had longer T Ct≥35than patients without comorbidities (a HR=0.38, P<0.001).The duration of T Ct≥28, T Ct≥30, T Ct≥33 and T Ct≥35 in children without underlying diseases were 7(6, 9) d, 9(7, 10) d, 10(8, 11) d and 12(10, 14) d, respectively. Conclusions:Age, vaccination, disease severity and underlying diseases could affect the duration of SARS-CoV-2 nucleotide turning to negative (Ct value≥35) in children infected with Omicron variants.

Résumé

In the non-specific immune system of human, neutrophils, lymphocytes, monocytes and platelets are important components that play a role in regulating and inducing tissue damage and can reflect the body′s level of immunity.These peripheral blood cells are functionally and quantitatively abnormal in the presence of serious infections or immune deficiencies, but these parameters are usually interpreted in isolation.Recent studies have found that comprehensive indicators derived from peripheral blood parameters, such as neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, monocyte to lymphocyte ratio or lymphocyte to monocyte ratio have predictive value for the occurrence and prognosis of diseases.This article reviews the role of these indicators in common childhood diseases and provides a reference for the diagnosis and treatment of some diseases.

Résumé

Malignant ovarian germ cell tumor (MOGCT) is a kind of primordial germ cell tumors deriving from embryonic gonads. It mainly occurs in adolescent women and is characterized with the rapid growth and high degree of malignancy. The traditional treatment methods include whole uterus and bilateral accessory resection or tumor cytoreductive surgery, although the patients have recovered after surgery, they lose their reproductive function. With the progress of chemotherapy research, the treatment mode of MOGCT has undergone fundamental changes, which provides new possibility of maintaining the reproductive function of patients with MOGCT.

Résumé

Objective@#To analyze the clinical features and factors associated with osteonecrosis in children with systemic lupus erythematosus (SLE).@*Methods@#A retrospective analysis of 15 SLE patients with osteonecrosis in Department of Pediatrics, Renji Hospital Affiliated to School of Medicine of Shanghai Jiaotong University from January 2013 to May 2017 was carried out.Forty-two SLE patients without osteonecrosis were selected as control group.The clinical, laboratory variables and the treatment were compared among SLE patients who were with and without osteonecrosis.@*Results@#(1) Fifteen patients developed osteonecrosis that constituted 8.6% of all the 175 hospitalized SLE patients during the same period.(2) Of 15 patients, 2 patients were male, 13 patients were female, who developed osteonecrosis with an average age of (13.9±2.7) years (range: 10-18 years old). The duration of SLE before the diagnosis of osteonecrosis ranged from 6 days to 141 months, the median was 10 months, and 80.0% (12/15 cases) was diagnosed with osteonecrosis within 2 years of SLE diagnosis.There were 36 joints involved in 15 patients, all of which were detected by magnetic resonance imaging(MRI). The knees were the most commonly involved joints(14/15 cases, 93.3%), followed by hip and ankle joints.(3) Univariate analysis revealed that the level of Triglyceride [(2.080±1.500) mmol/L vs.(1.350±0.945) mmol/L], maximum daily dose of glucocorticoid[(1.25±0.33) mg/kg vs.(1.07±0.22) mg/kg], positive rate of gene associated with glucocorticoid-induced osteonecrosis of femoral head(100.0% vs.54.8%)were significantly higher in SLE with osteonecrosis than those in controls(all P<0.05). While the level of 25(OH)D3[(21.37±11.29) μg/L vs.(31.45±17.73) μg/L] was significantly lower than that of controls(P<0.05). Multiple factor Logistic regression analysis showed that hypertriglyceridemia and daily maximum dose of glucocorticoid were the risk factors for osteonecrosis.@*Conclusions@#Osteonecrosis mostly occurred in children over 10 years old, knee joint involvement is the most common.The high-risk time of osteonecrosis is within 2 years of SLE diagnosis.Hypertriglyceridemia and daily ma-ximum dose of glucocorticoid are risk factors associated with osteonecrosis in children with SLE.
