Acute lymphoblastic leukemia (ALL) is the most common cancer in children around the globe. Mexico City has one of the highest incidence rates of childhood leukemia worldwide with 49.5 cases per million children under the age of 15 which is similar to that reported for
We performed a prospective study to evaluate the efficacy and safety of low-dose cyclosporine A (CSA) treatment in paediatric lupus nephritis refractory to conventional therapy. Seven children with biopsy-proven Class III-IV lupus nephritis were treated with CSA (2-4 mg/kg/day) combined with low-dose prednisone for one year. All patients had failed to achieve sustained proteinuria remission with corticosteroids and cytotoxic drugs. Proteinuria decreased from median value of 2.5 g/24 hours (range, 1.2-4.9) to 0.14 g/24 hours (range, 0.0-0.84) after treatment (P = 0.018). Median values of creatinine clearance and serum creatinine did not change significantly. Median systemic lupus erythematosus disease activity index score decreased from 12 (range, 6-16) to 4 (range, 0-8) at end of treatment (P = 0.027). However, two patients experienced flares of extrarrenal manifestations and complement levels did not improve. Moreover, most patients relapsed with proteinuria within a few months of stopping CSA therapy. Side effects were not significant. In conclusion, low-dose of CSA combined with steroids appears to be useful to reduce proteinuria in paediatric proliferative lupus nephritis refractory to steroids and cytotoxic drugs; however, relapses are common after CSA discontinuation. Further studies are needed to define the precise role of CSA in paediatric lupus nephritis.
Our results confirm that cyclical pamidronate infusions reduce the incidence of bone fractures and allow normal growth. The improvement in bone mass initially observed after the first 2 y of therapy is not always sustained over the following years despite maintenance of therapy.
Although, decreasing in incidence with the disconnection systems, the first complication is still peritonitis in patients with chronic renal failure and the second is infection of Tenckhoff catheter exit-site. All efforts made to diminish the frequency of exit-site infection lower the possibility of peritonitis. The pediatric population is well-known to have a major risk of infectious complications, and making easy and safe the care of the exit-site will prevent the peritonitis that follows. The aim of the study was to evaluate the efficacy of the Amuchina 10% solution vs. pH neutral soap in children with chronic renal failure, on preventing exit-site infection. There were 60 patients who were assigned randomly to one of two groups. One group used Amuchina 10% solution for the daily cleaning of the exit-site, and the other used pH neutral soap, with 14 months of follow-up. Before the study they have to be free of infection for at least 30 days. All were taught by the same nurse how to clean their exit-site. Groups were almost identical in years, sex, and time on dialysis. We had nine infections in the soap group and none in the Amuchina 10% solution group, with an OR: 17 (p = 0.004). From these nine infections, the bacteria isolated were: 4 (13%) were caused by Pseudomona aeruginosa, 1 (3.3%) by Staphylococcus aureus, coagulase-positive staphylococci in 2 (6.6%) and Serratia marcensens in 1 (3.3%). In conclusion, Amuchina 10% solution is effective in preventing infection on the exit-site, without any secondary topical reaction.
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.
