Clinical characteristics of bronchiolitis caused by human metapneumovirus in infants.
Chinese Journal of Pediatrics.2004;42(5):383-386.
OBJECTIVEThe fact that the acute lower respiratory infections (ALRI) are associated with a newly discovered virus, human metapneumovirus (hMPV), has been shown in several studies. The authors conducted this study to understand the etiological and clinical characteristics of bronchiolitis, one of the most common ALRI in infants, caused by hMPV.
METHODSNasopharyngeal aspirate specimens from 54 out of 126 infants with bronchiolitis admitted to the Children's Hospital Affiliated to Capital Institute of Pediatrics, Beijing from November 2002 to February 2003 were examined for hMPV gene fragments by reverse transcription-polymerase chain reaction (RT-PCR). Prior to the detection, the specimens were confirmed as negative for the common respiratory pathogens including RSV, influenza A and B, parainfluenza I, II, III, adenovirus, Mycoplasma pneumoniae by indirect immunofluorescence test, virus isolation and ELISA test. The clinical data of the patients diagnosed etiologically as hMPV infection analyzed included the infants' age, sex, the degree of fever, the severity of wheezing and clinical Lowell score, the findings of chest examination and chest X-ray, the white blood cell count and blood gas analysis, the course of the disease, the major treatments and the outcome of the disease.
RESULTSTwenty-one specimens showed the predicted 213 bp PCR products in agarose gel and the positive rate was 16.7% of all patients (21/126) and 39% of the patients with negative results for common respiratory pathogens detections (21/54). The range of patients' age was 2 - 15 months and the young infants with hMPV bronchiolitis (1 - 6 month of age) accounted for 62% and the male:female ratio was 3.2:1. The patients presented a low-medium grade fever (T < 39 degrees C) accounted for 86%; 81.0% of patients had a white blood cell count lower than 10.0 x 10(9)/L. The radiological findings were patchey opacity in both lungs (68%) and(or) hyperinflation (62%). Assessed by the Lowell score system, 5 out of 21 cases were considered as severe cases. The major clinical findings of hMPV bronchiolitis had no significant difference compared with that of subgroup A hRSV bronchiolitis, and showed longer course of disease than that of subgroup B hRSV bronchiolitis (P < 0.01).
CONCLUSIONSOf the infants with bronchiolitis hospitalized in our hospital from November of 2002 through February of 2003, 16.7% were caused by hMPV infection. These data showed that the major clinical characteristics and the outcome of treatment of hMPV bronchiolitis had no statistically significant difference compared to the cases with either subgroup A or subgroup B hRSV infection.

OBJECTIVEPropylthiouracil (PTU) as a drug used during the treatment of hyperthyroidism could induce antineutrophil cytoplasmic autoantibody-positive vasculitis. Here the author reported a childhood case of antineutrophil cytoplasmic autoantibody-positive vasculitis induced by PTU, which is rarely described.
METHODSThe diagnosis was made according to the symptoms, signs, serum markers and renal biopsy, and the relevant literature was reviewed.
RESULTSThe 12-year-old girl presented with gross hematuria, proteinuria, renal function damage [Ccr 52.46 ml/(min. 1.73 m(2))], positive antineutrophil cytoplasmic autoantibody (ANCA-MPO) (MPO ELISA 140%) and a vasculitis lesion in the renal biopsy sample. She had been treated with PTU for 5 years because of Graves disease. After the diagnosis, the PTU was withdrawn, and prednisone (40 mg/d) and cyclophosphamide (25 mg, Bid) were applied. Three weeks after the therapy with prednisone and cyclophosphamide the gross hematuria disappeared. Three months after the treatment the renal function returned to normal [Ccr 124 mg/(min.1.73 m(2))], and the titer of ANCA-MPO decreased from 140% to 57%.
CONCLUSIONPTU may induce antineutrophil cytoplasmic autoantibody positive vasculitis. A right diagnosis and treatment can improve its prognosis of the disease.

Effect of elastase inhibitor on pulmonary hypertension induced by monocrotaline.
Chinese Journal of Pediatrics.2004;42(5):375-378.
OBJECTIVEPulmonary hypertension is a proliferative vascular disease characterized by pulmonary vascular structural remodeling. Until now, the pathogenesis of pulmonary hypertension is still not fully understood. Although considerable progress has been made, there is, to date, no cure for advanced pulmonary vascular disease. Recently, a number of studies suggest that endogenous vascular elastase (EVE) play a role in the vascular changes associated with pulmonary hypertension. The purpose of the study was to determine whether an elastase inhibitor might reverse advanced pulmonary vascular disease produced in rats by injection of monocrotaline.
METHODSOne hundred and twenty male Sprague-Dawley rats were used in this study. The rats were divided into three groups: control, model and ZD-0892 groups. In the model and ZD-0892 groups, the rats were subjected to a single subcutaneous injection of monocrotaline (60 mg/kg) in the hind flank, while the rats in control group received an equivalent volume of 0.9% saline. From day 21, the rats in the ZD-0892 and model groups received twice-daily gavage tube feedings of either ZD-0892 at a dose of 240 mg/kg per day or its administration vehicle, while the rats in control group were subjected to an equivalent volume of 0.9% saline. On days 21, 28 and 35 post-injection, the elastolytic activity was measured with a fluorescence microplate reader and pulmonary artery pressure was detected via catheterization. Meanwhile, the lungs were evaluated morphologically, using the barium-gelatin perfusion technique.
RESULTSThe injection of monocrotaline led to severe pulmonary hypertension in rats 21 days later and pulmonary artery elastolytic activity increased remarkably. A 1-week treatment with ZD-0892 resulted in declines in elastase activity. This was associated with significant declines in pulmonary artery pressure, decreases in muscularization of peripheral arteries and reductions in medial hypertrophy. After 2 weeks, elastase activity returned to normal level. Pulmonary artery pressure and structure were normalized.
CONCLUSIONIncreased elastase activity is important in the development of vascular changes and progressive pulmonary hypertension. ZD-0892 can suppress the elastase activity and completely reverse the fatal pulmonary hypertension induced by monocrotaline in rats.
