AimOur aim was to update the recommendations for the diagnosis, treatment and follow‐up of the first febrile urinary tract infection in young children, which were endorsed in 2012 by the Italian Society of Pediatric Nephrology.MethodsThe Italian recommendations were revised on the basis of a review of the literature published from 2012 to October 2018. We also carried out an ad hoc evaluation of the risk factors to identify children with high‐grade vesicoureteral reflux or renal scarring, which were published in the previous recommendations. When evidence was not available, the working group held extensive discussions, during various meetings and through email exchanges.ResultsFour major modifications have been introduced. The method for collecting urine for culture and its interpretation has been re‐evaluated. We have reformulated the algorithm that guides clinical decisions to proceed with voiding cystourethrography. The suggested antibiotics have been revised, and we have recommended further restrictions of the use of antibiotic prophylaxis.ConclusionThese updated recommendations have now been endorsed by the Italian Society of Pediatric Nephrology and the Italian Society for Pediatric Infectivology. They can also be used to compare other recommendations that are available, as a worldwide consensus in this area is still lacking.
ARFI values decrease from kidneys with secondary vesicoureteral reflux to kidneys with primary reflux to unaffected kidneys contralateral to reflux to normal kidneys.
Nephropathic cystinosis (NC) is a severe disease that is complicated by early-onset chronic renal failure (CRF) and other complications related to cystine deposition in tissue. Since the 1980s, the prognosis of NC has dramatically improved after the introduction of cysteamine treatment. Limited data are available documenting improvement in prognosis. We reviewed our long-term data (follow-up 6.3-27.8 years) on 23 patients followed in the past 26 years. Overall, stage III CRF was reached at 10 years of age in >90% of patients, whereas >80% reached end-stage renal disease before the age of 14 years. Three patients died during the follow-up. Our analysis shows a clear improvement in renal outcome (p = 0.001) and linear growth (p = 0.04) in patients treated more recently. Improvement in the evolution of renal function was significantly associated with early initiation of cysteamine (p = 0.006), with the dose of cysteamine (p = 0.04), and with the use of angiotensin-converting enzyme inhibitors (p = 0.01). Nonrenal long-term complications are similar to previously reported data. Of note, 3/23 patients developed rare forms of primary tumors that were successfully treated. In conclusion, our experience shows a significant improvement in the renal and nonrenal complications of cystinosis over the past decades and highlights the importance of early diagnosis in order to initiate cysteamine as soon as possible.
Although severe kidney involvement in children with Henoch-Shonlein purpura (HSP) is rarer than that in adults, morbidity should not be underevaluated and follow-up is mandatory. Some drugs are introduced as well-defined treatment options, others can be promising therapeutic alternatives.Therapy of HSP nephritis in children can range from simply steroids to combined immunosuppressant treatments. The prophylactic treatment for renal complication of patients with HSP has been sometimes suggested, but with conflicting results and ultimately not clearly proven. The treatment of overt HSP nephritis includes steroids and other immunosuppressant drugs. Methylprednisolone pulse therapy and prednisone per os are tested drugs. These steroids could be used in combination with other immunosuppressant drugs, such as cyclosporin A and cyclophosphamide. Unfortunately, of these two drugs, only cyclophosphamide is demonstrated as effective in a recent randomized controlled trial. However, since there are insufficient data and unstructured study designs, ACE-I, azathioprine, mycophenolate mofetil, and urokinase need to be more tested in childhood HSP nephritis. In addition to drugs, other techniques are used to treat the severe form of nephritis. Of these, in a multicenter study, plasmapheresis demonstrated efficacy in delaying the progression of kidney disease. However, no convincing studies have been made to date concerning either intravenous immunoglobulin, factor XIII administration, antioxidant vitamin E, and fish oil to treat HSP nephritis.
No impairment or differences in renal parameters were found in pre-school children born ELBW compared with those born with VLBW, except for differences in kidney volume, renal cortical thickness and urinary alpha1-microglobulin excretion. Thus, patients born with ELBW would require a longer follow-up period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
