ABSTRACT
Objective:To investigate the clinical manifestations, pathological characteristics, treatment and prognosis of pediatric rheumatic carditis with the initial symptom of acute heart failure, and to improve the clinical understanding of the disease.Methods:The clinical data, laboratory examination results, imaging findings, treatment and prognosis data of 10 cases with acute rheumatic carditis were collected and analyzed retrospectively.The patients pre-sented with acute heart failure as the first symptom and were treated in Shenzhen Children′s Hospital from January 2015 to February 2022.Results:There were 4 males and 6 females in this study.The mean age was 9.1 years (3 years and 1 month to 11 years and 3 months), and the average onset age was (9.3 ± 3.2) days (4-14 days). All the 10 cases had circulation symptoms.Besides, 4 cases were also complicated with joint symptoms, 3 cases with neurological symptoms and 2 cases with skin symptoms.Echocardiography revealed mitral valve diseases in all cases.More specifically, combined valve diseases were found in 5 cases, pure mitral regurgitation in 3 cases, and mixed mitral valve diseases (mitral regurgitation complicated with mitral stenosis) in 2 cases.After receiving antibiotic therapy, anti-infection treatment and anti-heart failure therapy, symptoms improved in all patients and valve lesions were alleviated.All patients were followed up for 6 months to 6 years.Six cases had persistent rheumatic heart disease during the follow up.Conclusions:Pediatric rheumatic carditis with the initial symptom of acute heart failure is characterized by early onset and the typical manifestation of rheumatic fever.Mitral valve disease is the commonest lesion.Echocardiography is of great value for the early diagnosis of the disease.Medical treatment is effective, but the incidence of chronic rheumatic heart disease is still high.
ABSTRACT
Objective@#To retrospectively analyze the laboratory findings and ultrasonographic features in acute phase of children suffering from Kawasaki disease (KD) with stable hemodynamics and Kawasaki disease shock syndrome (KDSS), so as to provide the evidence for early diagnosis, timely treatment and improvement of prognosis of KDSS.@*Methods@#Four hundred and eighteen patients with KD diagnosed at Shenzhen Children′s Hospital from November 2016 to May 2018 were selected, including 23 KDSS patients(KDSS group) and 395 cases with stable hemodynamic(KD without shock group). The clinical characteristics, laboratory index and ultrasonic examination data of the 2 groups were collected and compared for statistical conclusion.@*Results@#(1)The level of C-reaction protein(CRP)[166.20 mg/L (74.40 mg/L)], γ-glutamyl transpeptidase(γ-GT)[88.00 IU/L (126.00 IU/L)], creatine kinase isoenzyme(CKI)[1.78 μg/L (5.17 μg/L)], troponin(TP)[0.01 μg/L (0.39 μg/L)] in the KDSS group in acute phase were all higher than those in the KD without shock group[70.50 mg/L (54.30 mg/L), 40.00 IU/L (89.00 IU/L), 1.20 μg/L (0.85 μg/L), 0.01 μg/L (0.01 μg/L)], hemoglobin(Hb)[90.00 g/L (15.00 g/L)], ablumin [24.20 g/L (4.30 g/L)], serum sodium[130.90 mmol/L (5.60 mmol/L)] levels in the KDSS group were lower than those in the KD without shock group[107.00 g/L (14.00 g/L), 33.40 g/L (4.08 g/L), 136.10 mmol/L (3.25 mmol/L)], and the differences were statistically significant (all P<0.05). (2)The incidence rates of impaired left ventricular ejection fraction(LVEF)[<55%: 3 cases (13.03%) vs.8 cases (2.00%)], coronary artery abnormalities[left anterior descending branch(LAD) Z-score>2.5: 6 cases (26.09%) vs.35 cases (8.86%)]and valvular regurgitation[tricuspid regurgitation(TR)≥moderate: 3 cases (13.03%) vs.5 cases (1.26%)]in the KDSS group were higher than those in the KD without shock group, and the differences were statistically significant (all P<0.05). (3)Among acute phase in KDSS group, 9 cases (39.13%) had liver enlargement, 9 cases (39.13%) had peritoneal effusion, 3 cases (13.04%) had diffuse renal lesions, 3 cases (13.04%) had joint effusion (2 cases of knee joint effusion, 1 case of hip joint effusion), and 2 cases (8.70%) had enteritis.In the KD without shock group, only 3 cases (0.76%) had hepatomegaly and 2 cases (0.51%) had a small amount of knee effusion.@*Conclusions@#Laboratory findings of KDSS group showed higher level of CRP, CKI, TP as well as γ-GT than those in KD without shock group, who are more prone to suffer from hypohemoglobin, hyponatremia and hypoalbuminemia.Ultrasound examination showed that KDSS children were more prone to have heart or multiple-organ damage.Clinicians should raise their awareness to provide comprehensive assessment as well as timely and effective treatment.
ABSTRACT
Objective To study the status of electrolyte imbalance in infant with moderate to severe malnutrition and discuss reasonable clinical therapy.Methods we examined serum level of electrolyte and analyse retrospectively.96 infants were divided into three group-pneumonia,diarrhea and mixed group,difference of electrolyte imbalance was compared within the three groups.Results Hypokalemia and hyponatremia were the major electrolyte imbalamce.60.4% had hypokalemia,55,2% had hyponatremia;the other imbalance,46.9% had hypochloremia,40.6% had hypocalcemia,32.3% had hypomagnesemia,30.2% had metabolic acidosis and 16.6% had metabolic alkalosis.Conclusions The pneumonia group was more likely to have hyponatremia,and the diarrhea group was more likely to have hypokalemia.Serum level of chloride fluctuated with the change of blood potassium.Hypomagnesemia and hypocalcemia were normal and were influenced by acid-base balance.Acidosis was more likely to be found in diarrhea group,and was metabolic in most situation.There was a trend of emerging metabolic alkalosis in severe dehydration patient.
