Echocardiography, anemia and thrombocytosis are useful early differentiating features between KDSS and TSS patients.

Hemodynamic compromise arrhythmia is common in AFM patients and may cause rapid deterioration. Simply correcting sinus rhythm is not always sufficient because of myocardium instability. Timely use of ECMO can improve the survival rate and shorten the time to recapture sinus rhythm in AFM patients with CAVB or VT.

Our results indicated that L-NAME/SHR is a useful model for hypertensive nephrosclerosis in young rats. The blood pressure-lowering and renoprotective effects of melatonin is due to increases of DDAH activity, decreases of ADMA, and reduction of oxidative stress in L-NAME-treated SHR kidney. Specific therapy targeting the DDAH-ADMA pathway may be a promising approach to slowing chronic kidney disease progression in children.

Background Serum C‐reactive protein (CRP) is a sensitive biomarker for inflammation and is broadly used to clinically diagnose infectious diseases, including pneumonia. However, blood sampling is fraught with technical difficulties in children. The salivary analysis may be a potential diagnostic tool, as it is noninvasive, patient‐friendly, and easy to perform in children. This study aimed to evaluate the use of salivary CRP as a biomarker for children with pneumonia. Methods A prospective study was conducted in patients aged 2 to 17 years, admitted to the hospital with pneumonia. Saliva and serum samples for CRP and chemokine determination were collected at the initial admission and during a follow‐up from pediatric patients with pneumonia. Salivary samples were also collected from healthy subjects used as controls. Results A total of 60 healthy children and 106 pediatric patients with pneumonia were enrolled in this study. The salivary CRP level was much higher in pediatric patients with pneumonia than in healthy children (48.77 ± 5.52 ng/mL vs 14.78 ± 3.92 ng/mL; P < .001). Salivary CRP level was highly correlated with serum CRP level in pediatric patients with pneumonia (r = .679; P < .001). Salivary CRP level (≥40.307 ng/mL) can be used to predict high serum CRP levels (≥80 mg/L) with an area under the curve of 0.810 (95% confidence interval, 0.740–0.881). As pneumonia improved, both salivary and serum CRP levels decreased during follow‐up. Conclusions Salivary CRP could be an alternative biomarker for serum CRP in pediatric patients with pneumonia. This is especially beneficial for pediatric patients, as saliva collection is simple, noninvasive, and patient‐friendly.

Community-acquired pneumonia (CAP) is common among children and can be fatal in certain conditions. In children, CAP can be caused by viral or bacterial infections. Identification of pathogens can help select appropriate therapeutic strategies. Salivary analysis may be a potential diagnostic tool because it is noninvasive, patient-friendly, and easy to perform in children. A prospective study was conducted in children with pneumonia admitted to a hospital. Salivary samples from patients with definite Streptococcus pneumoniae and influenza A strains were used for gel-free (isobaric tag for relative and absolute quantitation (iTRAQ)) proteomics. No statistically significant difference was detected in salivary CRP levels between Streptococcus pneumoniae and influenza A pneumonia in children. Several potential salivary biomarkers were identified using gel-free iTRAQ proteomics to differentiate pneumonia from Streptococcus pneumoniae or influenza A virus infections in pediatric patients. ELISA validated that Streptococcus pneumoniae group has a higher abundance of salivary alpha 1-antichymotrypsin than those in the influenza A group. Whether these salivary biomarkers can be used to distinguish other bacteria from viral pneumonia requires further verification.
