[Acute renal failure following Chlamydia pneumoniae pneumonia in a child]. / Insuffisance rénale aiguë consécutive à une pneumonie à Chlamydia pneumoniae chez l'enfant.

Acute renal failure (ARF) following Chlamydia pneumoniae pneumonia is rarely reported in adults. We present an observation in a 10-year-old child, who had C. pneumoniae pneumonia treated with roxithromycin for a period of 10 days, without any other nephrotoxic drug, in particular nonsteroidal anti-inflammatory drugs. At the end of antibiotic treatment, he presented with asthenia, polyuria, polydipsia, increased plasma creatinine, metabolic acidosis, hypokalemia, and markers of tubular damage. The etiological investigations showed positive C. pneumoniae antibodies, increased serum concentrations of C3 and C4 complement, IgA, and IgG. No uveitis was noted. The diagnosis was tubulointerstitial nephropathy after C. pneumoniae pneumonia. C. pneumoniae pneumonia should be considered a differential diagnosis of community-acquired pneumonia, especially in cases of poor response to conventional antibiotic therapy. It may be associated with tubulointerstitial nephropathy and/or rapidly progressive glomerulonephritis whose severity varies in children as in adults. Early and effective treatment of C. pneumoniae infection with macrolide antibiotics usually provides favorable progression of renal function.

[Domiciliary assisted ventilation in children]. / Ventilation assistée à domicile chez l'enfant.

The concept of assisted ventilation in the home setting has greatly progressed as a routine practice. This technique was used from 1990 to 2000 in 16 children cared for at our center. Ten children had neuromuscular disease (infantile spinal amyotrophy 6, Duchenne myopathy 3, and mitochondrial myopathy 1) or other conditions including central hypoventilation (n = 2), traumatic tetraplegia (n = 2), encephalopathy with chronic bronchitis (n = 1) and bronchopulmonary dysplasia (n = 1). Only 5 children had a tracheotomy, the others were treated successfully with non-invasive ventilatory assistance. Initialization of non-invasive ventilatory assistance had been planned before development of respiratory failure in 4 of the 11 children, but generally was indicated after an episode of acute respiratory distress. Home ventilation, particularly with non-invasive assistance is a reliable method for long-term treatment of chronic alveolar hypoventilation in children. The appropriate time for initiating this therapy should be better defined.
