Severe primary cutaneous aspergillosis refractory to amphotericin B and the successful treatment with systemic voriconazole in two premature infants with extremely low birth weight.

Primary cutaneous aspergillosis is a rare, life-threatening, infectious complication in premature infants that may result in fulminant sepsis and subsequent multi-organ failure. In the past decade, the incidence of primary aspergillosis has increased significantly, whereas the high morbidity and mortality of invasive aspergillosis remains unaltered. In vitro studies reveal that more and more Aspergillus species seem to be refractory to the classical treatment with fluconazole or amphotericin B. This case report presents two extremely low birth weight infants (ELBW) with primary cutaneous aspergillosis, which was refractory to amphotericin B. Both patients were successfully treated with systemic voriconazole, an extended-spectrum triazole antifungal, supported by topical care. This paper provides the clinical manifestation, diagnostics and pharmacotherapy of primary cutaneous aspergillosis, as well as pharmacokinetic aspects of voriconazole in ELBW infants.

Recombinant activated factor seven in acute life-threatening bleeding in neonates: report on three cases and review of literature.

INTRODUCTION: Acute bleeding of different genesis can be a severe, life-threatening problem in neonatology. Recombinant factor seven (rFVIIa) is known to have unique hemostatic properties in adults and older children. CASE PRESENTATION: Three cases of acute life-threatening peri- and postnatal hemorrhage were successfully controlled after the application of fFVIIa. All infants were first treated with vitamin K, fresh-frozen plasma and platelet transfusion. CONCLUSION: The cases substantiate other reports that rFVIIa is an effective treatment for acute, refractory and life-threatening bleeding in neonates and premature infants.

A stepwise approach to the treatment of early onset nephrotic syndrome.

We have retrospectively reviewed our single-center experience of the treatment of early onset nephrotic syndrome (NS). From 1991 to 1998, ten children with NS were treated. Kidney biopsy showed focal sclerosis (n=1), diffuse mesangial sclerosis (n=7), and congenital NS of the Finnish type (n=2). Associated conditions included incomplete Drash syndrome (n=1), Galloway-Mowat syndrome (n=1), and severe mental and motor retardation of unknown origin (n=3). From 1991 to 1997, five children with NS were treated. Bilateral nephrectomy (NX) was performed in three, one patient with severe retardation died at 4 years and NX was not performed in one patient who showed satisfactory growth and development. Three of these children were dialyzed and two were successfully transplanted. One patient was transplanted without previous dialysis. From 1997 to 1998, five children were treated with a regimen that included captopril and indomethacin (CAPTO/INDO). CAPTO/ INDO was successful in increasing serum protein in all patients and producing growth and development in four patients. In two patients CAPTO/INDO was successful only after unilateral NX. Our experience indicates that CAPTO/INDO may be a valuable treatment in patients with early onset NS. An individualized stepwise approach including unilateral NX should be considered to achieve optimal results.

Antagonistic effects of vitamin D and parathyroid hormone on lipoprotein lipase in cultured adipocytes.

The effects of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) (calcitriol) and parathyroid hormone (PTH) on synthesis and secretion of lipoprotein lipase (LPL) were studied in 3T3-L1 adipocytes. Expression of the vitamin D receptor was demonstrated by saturation kinetics with radiolabeled calcitriol. Incubation with calcitriol (10(-8) M) for up to 4 d resulted in a time-dependent significant increase in heparin-releasable LPL activity (LPLa) accompanied by a significant increase in LPL mRNA. In contrast, incubation with intact (1-84) PTH (10(-6) to 10(-9) M) produced a time- and dose-dependent significant decrease in LPLa, but no change in LPL mRNA. The effect of PTH (24-h incubation, 10(-8) M) could be prevented by the calcium channel blocker verapamil. Coincubation with both calcitriol and PTH at equimolar concentration (10(-8) M) resulted in an increase in LPLa and LPL mRNA. These data indicate an antagonistic role for calcitriol and PTH in the regulation of LPL, possibly mediated by intracellular calcium, which may contribute to the alterations in lipoprotein metabolism occurring in uremia.
