Effects of claritromycin on inflammatory parameters and clinical conditions in children with bronchiectasis.

BACKGROUND: The effects of the macrolides cannot be ascribed to their antibacterial action alone. Their immunoregulatory and anti-inflammatory functions are significant too. They are frequently used in the treatment of diffuse panbronchiolitis and cystic fibrosis (CF). AIM: To evaluate the effects of a macrolide antibiotic [clarithromycin (CAM)] on the process of inflammation [by measuring IL-8, TNF-alpha, IL-10 levels and cell profiles in bronchoalveolar lavage (BAL) fluid], pulmonary function and sputum production in children with steady-state bronchiectasis, secondary to causes other than CF or primary immunodeficiencies. METHODS: Seventeen patients randomized to the treatment group received CAM and supportive therapies for 3 months and 17 patients in the control group were given supportive therapies only. RESULTS: Compared with the control group, the treatment group showed a significant decrease in IL-8 levels, total cell count, neutrophil ratios in BAL fluid and daily sputum production at the end of the third month. There was also a significant increase in the treatment group's BAL fluid macrophage ratios. The differences in pulmonary function test parameters were not significant. CONCLUSION: Use of CAM in children with steady-state bronchiectasis results in laboratory improvement by reducing the inflammatory processes in the lungs. No corresponding clinical improvement could be shown but although this is possible with long-term use, trial validation is necessary.

Xanthoma disseminatum: a child with respiratory system involvement and bronchiectasis.

Xanthoma disseminatum (XD) is a rare normolipemic mucocutaneous xanthomatosis due to the proliferation of non-x histiocytes. Occasional involvement of the upper respiratory system has been reported, but lower respiratory tract involvement is very rare. Here, we present a child with severe involvement of the upper and lower respiratory tract by XD and bronchiectasis in the lower lobes of both lungs. The patient was an 8-year-old boy who was admitted to our hospital because of red-brown papules which developed on the skin and progressive dyspnea. He was diagnosed as having XD by skin biopsy. Physical examination revealed disseminated, numerous yellow-reddish brown papular xanthomas on the forehead and eyelids, around the neck and axillary area, and in the oral cavity and pharynx. He had respiratory distress and clubbing of the fingers. Chest x-rays showed hyperaeration and segmental atelectasis. High-resolution CT of the thorax revealed diffuse thickening of the whole tracheal and bronchial wall, and bronchiectasis in the lower lobes. Flexible fiberoptic bronchoscopy revealed numerous xanthomatous lesions in the nasal cavity, nasopharynx, oropharynx, subglottic area, trachea, bifurcation, both main bronchi, and smaller bronchi. To the best of our knowledge, this is the first report of a child with typical lesions of XD with severe involvement of the lower respiratory tract and bronchiectasis.

Tracheoesophageal fistula due to disc-battery ingestion.

Ingestion of a disc battery can lead to hazardous complications including tracheoesophageal fistula (TEF), especially when the battery is impacted in the esophagus. Urgent esophagoscopic removal of the battery is essential in all cases. Persisting respiratory symptoms and/or feeding difficulty after removal should alert the surgeon to evaluate for TEF. Esophagography and/or esophagoscopy should be performed. Once the TEF is identified, conservative management is the initial treatment of choice. Delayed primary repair can be tried if spontaneous closure does not occur. The authors present a case of TEF secondary to disc-battery ingestion with review of the current literature and discuss the management of this rare but potentially life-threatening complication.

Antioxidant effect of beta-carotene in cystic fibrosis and bronchiectasis: clinical and laboratory parameters of a pilot study.

UNLABELLED: The carotenoids are potent antioxidants with the ability to quench singlet oxygen and other toxic oxygen species. The aim of this pilot study was to investigate the protective effect of beta-carotene on oxidant system in patients with cystic fibrosis (CF) and in patients with bronchiectasis (BE) caused by a reason other than CF. Eighteen children with CF and 15 children with BE followed in the Pediatric Chest Disease Unit of Hacettepe University, and 15 healthy children participated in the study. Compared with the controls, significantly lower plasma levels of beta-carotene were found in the CF group and significantly lower plasma levels of vitamin E in the CF and BE groups. The standardization of carotenoid levels for total cholesterol did not significantly attenuate these differences. In addition, there were significantly higher levels of malondialdehyde (a marker of lipid peroxidation) and tumour necrosis factor-alpha (TNF-alpha) in children with CF and in children with BE than in normal subjects. After 6 mo of beta-carotene supplementation, the plasma levels of beta-carotene and vitamin E increased and the plasma levels of TNF-alpha and malondialdehyde decreased in both groups. CONCLUSION: Potent antioxidants, beta-carotene and vitamin E are deficient in patients with CF and in patients with BE, and they are more susceptible to oxidative damage. These patients may benefit from beta-carotene supplementation.

Peripheral arterial thrombosis in systemic lupus erythematosis and nephrotic syndrome: possible association with protein S deficiency.

Arterial thrombosis in systemic lupus erythematosus (SLE) and nephrotic syndrome have been infrequently reported. A 16-year-old boy with SLE and longstanding nephrotic syndrome presented with peripheral arterial thrombosis when his lupus was at an inactive stage. He did not have antiphospholipid antibodies but had low serum antithrombin III and protein S levels. We suggest that the thrombotic event is not related to antiphospholipid antibodies but to nephrotic syndrome and possibly to acquired protein S deficiency.

Diploid-triploid and tetraploid mosaicism in a child with cryptogenic cirrhosis and membranous glomerulonephritis: a causal relationship or coincidental association?

We present a seven-year-old boy with cryptogenic cirrhosis, membranous glomerulonephritis, mild mental retardation and mildly dysmorphic changes. Chromosomal analysis showed diploid, triploid and tetraploid mosaicism which was detected both by cytogenetic study and flow cytometric analysis of nuclear DNA content. Complete tetraploidy and triploidy, usually lethal, are rare chromosomal disorders. This is the first reported case of diploid-triploid-tetraploid mosaicism with cryptogenic cirrhosis and membranous glomerulonephritis.
