Objective Acute organ embolism in children with Mycoplasma pneumoniae pneumonia (MPP) has been reported, but changes in coagulation are unclear. This study aimed to investigate changes in coagulation in children with MPP. Methods A total of 185 children with MMP (cases) and 117 healthy children (controls) were recruited. We measured prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and plasma fibrinogen (FIB) and D-dimer levels. Results Plasma FIB (3.39 ± 0.96 g/L vs 2.93 ± 0.6 6g/L, t = 4.50) and D-dimer (326.45 ± 95.62mg/L vs 263.93 ± 103.32mg/L, t=5.36) in MPP children were higher than controls and PT (9.54 ± 4.97S vs 11.48 ± 5.96S, t=3.05) and APTT (31.41 ± 12.01S vs 38.38 ± 11.72S, t=4.95) were shorter than controls. FIB, D-dimer, PT, and APTT were not different between the high IgM-titre and low-titre groups. The areas under the receiver operating characteristic curves in cases and controls for plasma FIB and D-dimer levels were 0.654 (95% confidence interval [CI], 0.593–0.716, P = 0.031) and 0.682 (95% CI, 0.619–0.744, P = 0.032), respectively. Conclusions Children with MPP have a higher risk of blood coagulation and thrombosis. Controlling these problems should be considered as soon as possible.

Abstract BACKGROUND: Analyze the clinical characteristics of Fulminant Mycoplasma pneumoniae pneumonia (FMPP), and identify the related factors predicting FMPP.METHODS: A retrospective case-control study was performed on 345 children with Mycoplasma pneumoniae pneumonia (MPP) hospitalized in our hospital from January 2017 to June 2019. The clinical features, laboratory data and radiological findings were compared between the FMPP group, refractory Mycoplasma pneumoniae pneumonia (RMPP)group and general Mycoplasma pneumoniae pneumonia (GMPP) group. RESULTS: FMPP patients (n=69) had a higher incidence of extra-pulmonary complications and more serious radiological findings(P<0.05), besides the days of fever and the days in the hospitals were longer. FMPP patients also need more complicated treatments(P<0.05). Meanwhile, the levels of white blood cell count(WBC), C-reactive protein(CRP), lactic dehydrogenase (LDH), interleukin (IL)-6, ferritin, D-dimer, fibrinogen(FG), alanine aminotransferase(ALT) and the percentage of neutrophils in the FMPP group were significantly higher than those in the RMPP group and the GMPP group (P<0.05). In ROC curve analysis, the percentage of neutrophils, WBC, CRP, LDH, IL-6, ferritin, D-dimer and ALT were contributed to identify FMPP patients. Multivariate logistic regression analysis showed that ferritin>174.15 ng/mL, IL-6>25.475pg/ml and pleural effusion have significant predictive effects on the early diagnosis of FMPP (P<0.01).CONCLUSION: FMPP patients presented more serious clinical manifestations. Ferritin>174.15 ng/mL, IL-6>25.475pg/ml and pleural effusion were clinical factors for FMPP.

Abstract Background: The levels of serum D-dimer (D-D) in children with Mycoplasma pneumoniae pneumonia (MPP) were assessed to explore the clinical significance of D-D levels in refractory MPP (RMPP). Method: A total of 430 patients with MPP were enrolled between January 2015 and December 2015 and divided into a general MPP (GMPP) group (n=306) and a RMPP group (n=124). Clinical data, D-D level, white blood cell (WBC) count, proportion of neutrophils (N%), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), alanine transaminase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) were compared between the two groups. Multivariate logistic regression was performed to identify independent predictors of RMPP. Results: (1) Hospitalization time, preadmission fever duration, total fever duration, WBC, N %, CRP, LDH, ESR, ALT, AST, and D-D were significantly higher in the RMPP group than those in the GMPP group (all P<0.05). (2) Correlation analysis showed that D-D was positively correlated with WBC, CRP, ESR, and LDH, and could be used to jointly evaluate the severity of the disease. (3) Multivariate logistic regression analysis identified preadmission fever duration, CRP, LDH and DD as independent risk factors for RMPP (all P<0. 05). D-D had the highest predictive power for RMPP (P<0.01). The D-D level also had a good ability to predict pleural effusion and liver injury (all P<0.01). Conclusion: Serum D-D levels were significantly increased in patients with RMPP, indicating that excessive inflammatory response and vascular endothelial injury with prolonged duration existed in this patient population. Increased levels of serum D-D may be used as an early predictor of RMPP and the occurrence of complications. Our findings provide a theoretical basis for the early diagnosis of RMPP, early intervention and excessive inflammatory response in the pathogenesis of mycoplasma.

Mycoplasma pneumoniae is a common atypical respiratory pathogen causing community-acquired pneumonia in children. Co-infection with other respiratory viruses is common in pediatric patients but super-infection with bacteria other than Streptococcus pneumoniae and Haemophilus influenzae is rare. The first case of Chromobacterium violaceum infection incubated during and manifested after pneumonia caused by Mycoplasma pneumoniae in a 12-month old girl without any known history of immunodeficiency is here reported. The patient developed fever with redness and swelling over the middle phalanx of the right hand index finger which progressed to the formation of skin abscess. Following a course of intravenous meropenem and surgical drainage of the skin abscess, the patient fully recovered and was discharged.

Abstract Objective The purpose of this study was to develop a model for predicting severe mycoplasma pneumoniae pneumonia (SMMP) in pediatric patients with MMP on admission by laboratory indicators. Methods Pediatric patients with MPP from January 2019 to December 2020 in our hospital were enrolled in this study. SMMP was diagnosed according to guideline for diagnosis and treatment of community acquired pneumonia in children (2019 version). Prediction model was developed according to the admission laboratory indicators. ROC curve and Goodness of fit test were analyzed for the predictive value. Results A total of 233 MMP patients were included in the study, with 121 males and 112 females, aged 4.541 (1–14) years. Among them, 84 (36.1%, 95% CI 29.9%-42.6%) pediatric patients were diagnosed as SMPP. Some admission laboratory indicators (IgM, eosinophil proportion, eosinophil count, hemoglobin, ESR, total protein, albumin and prealbumin) were found statistically different (P < 0.05) between non-SMMP group and SMMP group. Logistic regress analysis showed IgM, eosinophil proportion, eosinophil count, ESR, and prealbumin were independent risk factors for SMMP. According to these five admission laboratory indicators, Nomograph prediction model was developed. The AUC of the Nomograph prediction model was 0.777, and the goodness of fit test showed that the predicted incidence of the model was consistent with the actual incidence (χ2 = 244.51, P = 0.203). Conclusion We developed a model for predicting SMMP in pediatric patients by admission laboratory indicators. This model has good discrimination and calibration, which provides a basis for the early identification SMMP on admission.

Abstract Background Levels of serum D-dimer (D-D) in children with mycoplasma pneumoniae pneumonia (MPP) were assessed to explore the clinical significance of D-D level in refractory MPP(RMPP). Method: A total of 430 patients with MPP were enrolled between January 2015 and December 2015, and divided into a genera MPP (GMPP) group (n = 306) and a RMPP group (n = 124). Clinical data, D-D level, white blood cell (WBC) count, C-reactive protein (CRP), blood sedimentation (ESR), and lactate dehydrogenase (LDH) were compared between the two groups. Results (1) Hospitalization time, fever duration, WBC, CRP, LDH, ESR, and D-D were significantly higher in the RMPP group than in the GMPP group, (all P < 0.05). (2) Correlation analysis showed that D-D was positively correlated with WBC, CRP, ESR, and LDH, and could be used to jointly evaluate the severity of the disease. (3) The predictive values of WBC, CRP, ESR, LDH, and D-D for RMPP were further compared using area under the receiver operating characteristic curve(AUC) analysis. D-D had the highest predictive power for RMPP (AUC = 0.923, P < 0.01). When the D-D level was > 738 ng/ml, the predicted sensitivity of RMPP occurrence was 79.8% and the specificity was 93.5%. D-D level also had a good ability to predict pleural effusion and liver injury (AUC = 0.740, P < 0.01 and AUC = 0.812, P < 0.01, respectively). (4) After 1 week of treatment, the levels of D-D in both groups were lower than those before treatment (p < 0.01), but remained outside the normal range in 91.4% of participants, and were moderately or severely increased in 27.1% of the participants, all of whom were in the RMPP group. Conclusion Serum D-D levels were significantly increased in patients with RMPP, indicating that severe hypercoagulability and vascular endothelial injury with prolonged duration existed in this patient population. Increased levels of serum D-D may be used as an early predictor of RMPP and the occurrence of complications. Our findings provide a theoretical basis for the early diagnosis of RMPP, early intervention of hypercoagulability, and improvement of microcirculation therapy.
