RESUMO
BACKGROUND: In high-resource settings, the survival of children with immunocompromise (IC) has increased and immunosuppressive therapies are increasingly being used. This study aimed to determine the clinical characteristics, performance of diagnostic tools, and outcome of IC children with tuberculosis (TB) in Europe. METHODS: Multicenter, matched case-control study within the Pediatric Tuberculosis Network European Trials Group, capturing TB cases <18 years diagnosed 2000-2020. RESULTS: A total of 417 TB cases were included, comprising 139 children who are IC (human immunodeficiency virus, inborn errors of immunity, drug-induced immunosuppression, and other immunocompromising conditions) and 278 non-IC children as controls. Nonrespiratory TB was more frequent among cases than controls (32.4% vs 21.2%; P = .013). Patients with IC had an increased likelihood of presenting with severe disease (57.6% vs 38.5%; P < .001; odds ratio [95% confidence interval], 2.073 [1.37-3.13]). Children with IC had higher rates of false-negative tuberculin skin test (31.9% vs 6.0%; P < .001) and QuantiFERON-TB Gold assay (30.0% vs 7.3%; P < .001) results at diagnosis. Overall, the microbiological confirmation rate was similar in IC and non-IC cases (58.3% vs 49.3%; P = .083). Although the mortality in children with IC was <1%, the rate of long-term sequelae was significantly higher than in non-IC cases (14.8% vs 6.1%; P = .004). CONCLUSIONS: Children with IC and TB in Europe have increased rates of nonrespiratory TB, severe disease, and long-term sequelae. Immune-based TB tests have poor sensitivity in those children. Future research should focus on developing improved immunological TB tests that perform better in patients with IC, and determining the reasons for the increased risk of long-term sequelae, with the aim to design preventive management strategies.

BACKGROUND: Kawasaki disease (KD) is a type of vasculitis in which giant coronary artery aneurysms (CAAs) can occur. There are no specific guidelines for managing giant CAAs that develop quickly and are at risk of rupture. Regarding cardiovascular drugs, only beta-blockers are formally recommended in the acute phase of KD. CASE PRESENTATION: A 6-month-old male patient with multiresistant Kawasaki disease and giant CAAs that continued to enlarge after controlling systemic inflammation was examined. The patient required three doses of intravenous immunoglobulin, methylprednisolone pulses, and anakinra and infliximab to normalize systemic inflammation. Due to the rapid increment of aneurysms' dimensions and the risk of rupture, we introduced anticoagulant therapy and propranolol plus captopril, and titration doses were introduced according to a tolerated decrease in heart rate and arterial pressure. CAAs increment stabilized and slowly reduced their dimensions. CONCLUSIONS: The authors describe an atypical case of multiresistant KD with giant rapidly increasing CAAs even after controlling systemic inflammation. The introduction of a beta-blocker and an angiotensin-converting enzyme (ACE) inhibitor was demonstrated to be useful for stabilizing giant CAAs growth and reducing the potential risk of rupture.
RESUMO
INTRODUÇÃO: O síndrome de Alice no País das Maravilhas (SAPM) é uma entidade rara que pode ocorre no contexto de várias condições clínicas, sendo a infeção por vírus Epstein-barr (EBV) a mais comum nas causas infeciosas. Apresenta-se um caso de SAPM associado a infeção a EBV alertando para a necessidade de investigação etiológica destes casos. RELATO DE CASO: Criança de 8 anos, com síndrome de Asperger que, no contexto de amigdalite aguda e febre, surgiu com episódios paroxísticos de alguns minutos de metamorfopsias (macro e micropsia), distorção da perceção das vozes e sensação de medo. A ressonância magnética e o eletroencefalograma foram normais, e o exame citoquímico do líquor foi normal mas a polimerase chain reaction (PCR) foi positiva para vírus EBV. As serologias para EBV, repetidas 3 e 10 semanas após a avaliação inicial, confirmaram uma reativação da infeção por este agente. O doente ficou assintomático após 2 semanas e não houve recidivas. CONCLUSÕES: A investigação de metamorfopsias ou síndrome de SAPM é mandatória pois podem indiciar patologia grave, nomeadamente lesão cerebral ou epilepsia focal. Embora a doença seja rara a etiologia infecciosa deve ser excluída mesmo em doentes com perturbação prévia do comportamento.
INTRODUCTION: Alice in wonderland syndrome (AWS) is a rare condition which may occur as a sign of multiple conditions, with the most frequent infectious etiology being Epstein-barr virus (EBV) infection. We present a case of an AWS caused by EBV infection to alert for the need to investigate these cases. CASE REPORT: 8-year-old boy with Asperger syndrome who developed, in the context of tonsillitis and fever, brief paroxystic episodes of metamorfopsias (macro and micropsia), with voice perception distortion and fear. Physical exam was otherwise normal. Brian magnetic resonance and electroencephalogram were normal, liquor cytochemical exam was normal but Epstein-barr virus (EBV) polimerase chain reaction was positive. EBV blood serologies, repeated 3 and 10 weeks after the initial evaluation, confirmed the reactivation of this agent's infection. Symptoms succumbed 2 weeks after its beginning, with no relapses. CONCLUSIONS: Metamorfopsias or AWS impose etiological investigation because they may occur due to severe disease, namely cerebral lesion or focal epilepsy. Although it is a rare disease, infectious causes should be excluded, even in patients with previous disturbed behavior.
