ABSTRACT

OBJECTIVE: To summarize the clinical features of primary nephrotic syndrome (PNS) complicated by plastic bronchitis (PB) in children to provide guidance for treatment. METHODS: We conducted a retrospective review of the clinical data of 25 children hospitalized with NS complicated by PB in our Hospital between 10/2016 and 03/2019, and summarized the clinical manifestations, imaging and fiberoptic bronchoscopy (FOB) examinations, treatment course and outcome of them. RESULTS: 1). The 25 children, with a nephrotic syndrome (NS) course of one to 36 months, were all diagnosed with PB after FOB, among which 8 cases (32%) had respiratory failure and required ventilatory support. All of them started with respiratory symptoms such as fever and cough, and then suffered from dyspnea and progressive aggravation after 1-3 day(s) of onset, with rapid occurrence of bidirectional dyspnea and even respiratory failure in severe cases. 2). Laboratory test for pathogens: influenza A virus H1N1 (11 cases), influenza B virus (9 cases), adenovirus (3 cases) and mycoplasma pneumoniae (2 cases). There was no statistically significant difference (P>0.05) between children with common NS complicated by influenza virus (IV) infection (not accompanied by dyspnea) and those with kidney disease who developed PB in the white blood cell count, lymphocyte count, the inflammatory biomarkers C-reactive protein (CRP), procalcitonin (PCT) and humoral immunity (IgG level), yet the total IgG level was found significantly higher and the blood albumin level lower in the latter (P<0.05). 3). The 25 children were all examined with the FOB and treated with lavage, 15 of which had typical bronchial tree-like casts and 10 broken and stringy casts. Based on histopathological classification, all children were of Type I. 4). Twenty children (80%) with influenza were administered the antiviral drug Oseltamivir, 20 (80%) were treated with antibiotics, oral hormones were replaced with the same dosage of intravenous Methylprednisolone for 5 cases (20%), and 20 (80%) were intravenously administered gamma globulins (400-500 mg/kg x 3 days). These children showed a remarkable improvement after treatment and there were no deaths. CONCLUSION: NS children are at high risk of influenza virus infection. Children with a severe case of NS are more susceptible to PB. If symptoms like shortness of breath, wheezing and progressive bidirectional dyspnea occur, FOB examination and lavage treatment should be performed as early as possible. Hyper-IgE-emia and hypoproteinemia may be the high risk factors for PNS complicated by PB in children. ZIEL: Ziel der Studie war es, durch Zusammenfassung der klinischen Merkmale des primären nephrotischen Syndroms (PNS) mit komplizierender plastischer Bronchitis (PB) im Kindesalter eine Orientierungshilfe für die Therapie der Erkrankung zu geben. METHODIK: Wir führten eine retrospektive Prüfung der klinischen Daten von 25 Kindern durch, die zwischen Oktober 2016 und März 2019 in unser Krankhaus aufgenommen wurden, und erstellten eine Zusammenfassung der klinischen Symptome, Untersuchungen mit bildgebenden Verfahren und fiberoptischer Bronchoskopie (FOB), des Therapieverlaufs und des Outcomes der Patienten. ERGEBNISSE: 1). Bei den 25 Kindern bestand ein nephrotisches Syndrom (NS) über einen Zeitraum von einem bis 36 Monaten. Bei allen Patienten wurde die Diagnose PB nach FOB gestellt, wobei in 8 Fällen (32%) eine beatmungspflichtige respiratorische Insuffizienz vorlag. Alle Patienten zeigten anfänglich Symptome einer Atemwegserkrankung wie Fieber und Husten, gefolgt von Atemnot und progredienter Verschlechterung 1 bis 3 Tage nach Erkrankungsbeginn. Dabei kam es rasch zum Auftreten bidirektionaler Atemnot, in schweren Fällen bis hin zur respiratorischen Insuffizienz. 2). Laboruntersuchung auf Erreger: Influenza-A-Virus H1N1 (11 Fälle), Influenza-B-Virus (9 Fälle), Adenovirus (3 Fälle) und Mycoplasma pneumoniae (2 Fälle). Es fand sich kein statistisch signifikanter Unterschied (P>0,05) zwischen Kindern, die ein "gewöhnliches" NS mit komplizierender Influenza-Virus (IV)-Infektion (ohne begleitende Atemnot) aufwiesen, und Kindern mit Nierenerkrankung, die eine PB entwickelten, hinsichtlich der Leukozyten- und Lymphozytenwerte sowie der Entzündungsmarker C-reaktives Protein (CRP), Procalcitonin (PCT) und humorale Immunität (IgG-Wert). Allerdings wurde bei der letzteren Patientengruppe ein signifikant höherer Gesamt-IgG-Wert und ein signifikant niedriger Albumin-Spiegel im Blut nachgewiesen (P<0.05). 3). Bei allen 25 Kindern erfolgte eine FOB und Therapie mit Lavage, bei 15 Kinder fanden sich typische verzweigte Ausgüsse der Bronchialäste und bei 10 Patienten desintegrierte und zähe Ausgüsse. Gemäß der histopathologischen Klassifikation waren alle Kinder vom Typ I. 4). Zwanzig Kinder (80%) mit Influenza erhielten das Virostatikum Oseltamivir, 20 Kinder (80%) eine Antibiotikatherapie, in 5 Fällen (20%) wurden oral gegebene Hormone durch intravenös in derselben Dosis verabreichtes Methylprednisolon ersetzt und 20 Kinder (80%) erhielten intravenös verabreichte Gammaglobuline (400-500 mg/kg Körpergewicht x 3 Tage). Diese Kinder zeigten eine bemerkenswerte Verbesserung nach der Therapie und es traten keine Todesfälle auf. SCHLUSSFOLGERUNG: Bei Kindern mit NS besteht ein hohes Risiko für eine Influenza-Virus-Infektion. Kinder mit schwerem NS sind anfälliger für PB. Bei Auftreten von Symptomen wie Atemnot, Giemen und Brummern sowie progredienter bidirektionaler Dyspnoe sollte baldmöglichst eine FOB-Untersuchung und eine therapeutische Lavage durchgeführt werden. Erhöhte IgE-Werte im Blut und Hypoproteinämie stellen möglicherweise Risikofaktoren für PNS mit komplizierender PB im Kindesalter dar.

ABSTRACT

OBJECTIVE: To analyze the clinical characteristics of severely and critically ill children with 2009 influenza A (H1N1) infection. METHOD: Clinical data of 150 cases with 2009 influenza A (H1N1) virus infection confirmed with the use of a real-time polymerase-chain-reaction assay on nasopharyngeal swab specimens were analyzed. RESULT: Among 150 severely and critically ill children with 2009 influenza A (H1N1) virus infection, 103 were male, 47 were female; the median age was 5 years, 81(55%) were 5 years of age or older; 21 (14%) had underlying chronic diseases. The most common presenting symptoms were fever (95%), cough (89%), vomiting (23%), wheezing (19%), abdominal pain (16%), lethargy (7%), seizures (6%), myalgia (6%), and diarrhea (6%). The common laboratory abnormalities were increased or decreased white blood cells counts (40%), elevated of CRP (33%), LDH (29%), CK (25%) and AST (19%). Clinical complications included pneumonia (65%), encephalopathy (12%), myocarditis (5%), encephalitis (1%) and myositis (1%). All patients had received antibiotics before admission or on admission; 73% of patients had received oseltamivir treatment, 23% of patients had received corticosteroids; 32 (21%) were admitted to an ICU, 13 patients were intubated and mechanically ventilated. Fourteen patients with dyspnea who were irresponsive to the treatment experienced bronchoalveolar lavage with flexible bronchoscopy, and the branching bronchial casts were removed in 5 patients. Totally 145 (97%) patients were discharged, five (3%) died, three previously healthy patients died from severe encephalopathy, one patient died from ARDS, one previously healthy patient died from secondary fungal meningitis. CONCLUSION: Severely and critically ill children with 2009 influenza A (H1N1) virus infection may occur mainly in older children without underlying chronic disease. The clinical spectrum and laboratory abnormality of the patients can have a wide range. Neurologic complications may be common and severe encephalopathy can lead to death in previously healthy children. Early use of bronchoalveolar lavage with flexible bronchoscopy may reduce death associated with pulmonary complications.
