RESUMEN
INTRODUCTION AND OBJECTIVE: The purpose of this study was to describe the evolution of meningococcal disease (MD) in the city of Barcelona between 1988 and 2015 and to assess the impact of the vaccine against serogroup C. MATERIALS AND METHODOLOGY: The evolution of MD and by serogroup was analysed using the information included in the mandatory notification diseases registry. Incidences of all serogroups between the periods of before and after the implementation of the serogroup C vaccine in 2000 were compared. Vaccination coverage among cases, serogroup among vaccinated cases and mortality and case fatality rates were analysed. RESULTS: MD has evolved from an incidence rate in children aged under 1 of 63.09 cases per 100,000 in 1997-2000 to 15.44 per 100,000 in 2001-2015. All MD serogroups incidences decreased after the implementation of the vaccine, especially for serogroup C among children aged between 1 and 4. Since 2000 vaccine coverage in MD cases by this serogroup was 7.6% while in those affected by serogroup B it was 35.0% (p<.01). Among those vaccinated, 66.4% of cases were serogroup B and 5.2% were C (p<.01). Mortality and case fatality rates were 7.7% and 0.19/100,000 respectively, without significant changes in time regarding case fatality. CONCLUSIONS: Incidence caused by serogroups B and C has decreased after the systematic vaccination against serogroup C. Vaccination against serogroup B could further reduce the impact of this lethal disease which has not decreased during this period.

We present the case of a 21-month-old girl with two rare and life-threatening conditions, atypical haemolytic uraemic syndrome (aHUS) and haemophagocytic lymphohistiocytosis (HLH), triggered by a cytomegalovirus (CMV) infection. Soon after admission, the girl became anuric and required continuous venovenous haemodiafiltration.Initial treatments included methylprednisolone, fibrinogen and plasma infusion (for HLH), plasmapheresis (for thrombotic microangiopathy), immunoglobulins (for inflammation), ganciclovir (for CMV infection) and the antibiotic cefotaxime. On day 5, eculizumab (600 mg) was given for aHUS, with rapid improvement in haematological and nephrological parameters. Despite a subsequent isolated episode of right heart thrombosis that resolved with heparin treatment, the patient showed a favourable response to eculizumab (300 mg/15 days), with improved renal function, normal haematological values, and no treatment complications. In conclusion, eculizumab effectively treated aHUS in this case despite a comorbid immunological disease.

Haemorrhagic cystitis is an uncommon and, in its severe form, potentially life-threatening complication of haematopoietic stem cell transplantation or cancer therapy in children. The severe form involves macroscopic haematuria with blood clots, urinary obstruction and/or renal impairment. There are many therapeutic options to treat acute haemorrhage, but only recombinant factor VII has a high level of clinical evidence in children. Supraselective vesical artery embolization (SVAE) is an increasingly used therapeutic procedure for controlling haemorrhage in adults, but is less commonly used in children. This might be due to several factors, such as the invasive nature of the procedure, lack of appropriate medical experience and possible long-term side effects. We present three cases of children successfully treated by means of effective SVAE.
