Urological outcomes in children with congenital Zika syndrome: The experience of a cohort in Campina Grande, Brazil.

OBJECTIVE: To describe the urological outcomes in children with congenital Zika syndrome (CZS) and investigate the relationship between clinical and urological findings in this population. METHODS: This cross-sectional study involved children with CZS followed up by a referral centre for children with microcephaly in the state of Paraiba in northeast Brazil. The urological evaluation included clinical history, urine culture results, ultrasonography of the urinary tract, and urodynamic evaluation, following the protocol proposed by Costa Monteiro et al. (2017). Descriptive statistical analysis was performed in addition to association and correlation tests, considering clinical and urodynamic variables. RESULTS: Among the 88 children with CZS (35.5 ± 5.5 months), 97.7% had microcephaly, and 51% presented urinary tract infection (UTI) confirmed with clinical history and lab tests. The number of confirmed UTI episodes varied from one to 14 per child. The urodynamic evaluation confirmed the presence of an overactive bladder in 78 children and incomplete voiding in 50. Urodynamic findings were associated with the number of confirmed UTI episodes, child's sex, and actual weight, in addition to the use of anticonvulsant and myorelaxant drugs. CONCLUSIONS: UTIs were confirmed in most children. Other urological outcomes observed were overactive bladder and low bladder capacity, which were associated with the number of confirmed UTI episodes, use of anticonvulsants and myorelaxants, and the child's sex and weight. These are treatable conditions, and it is paramount that paediatricians, neonatologists, and infectious disease specialists are aware of them to make clinical decisions and help reduce the risk of renal damage and other morbidities.

Mental health and burden in mothers of children with congenital Zika syndrome during COVID-19 pandemic / Saúde mental e sobrecarga das mães de crianças com síndrome congênita do Zika durante a pandemia de COVID-19

Abstract Objectives: to evaluate burden, frequency of anxiety and signs and symptoms of depression in mothers of children with congenital Zika syndrome (CZS) during the COVID-19 pandemic and the social isolation period. Methods: this is a cross-sectional study conducted with mothers who care for their children with CZS. The data were collected by an online form with questions regarding mother's socioeconomic conditions and questions related with Zarit burden scale and Beck's inventories on depression and anxiety. Spearman's correlation tests and multiple regression analyzes were performed to assess factors related to mothers' burden and mental health. Results: 41 mothers were evaluated, 51.2% had mild burden, 39% had minimal anxiety and 73.2% did not have signs and symptoms of depression. Negative correlations were observed between levels of burden and maternal schooling (p=0.01), presence of signs and symptoms of anxiety and receiving financial aid (p<0.04) as well as the presence of signs and symptoms of anxiety and having children with seizures history (p=0.03). Conclusion: despite the risk of their children again being victims of an epidemic virus, mothers who care for their children with CZS did not present serious mental health impairments.

Resumo Objetivos: avaliar a sobre carga e frequência de sinais e sintomas de ansiedade e depressão em mães de crianças com síndrome congênita do Zika (SCZ) durante pandemia de COVID-19. e o período de isolamento social. Métodos: trata-se de um estudo transversal realizado com mães que cuidam de seus filhos com SCZ. Os dados foram coletados por meio de um formulário online contendo questões referentes as condições socioeconômicas da mãe além da escala de sobrecarga de Zarite dos inventários de Beck de depressão e ansiedade. Para avaliação de fatores relacionados a sobrecarga e saúde mental das mães foram realizados testes de correlação de Spearman e análises de regressão múltipla. Resultados: ao todo foram avaliadas 41 mães das quais 51,2% apresentaram sobrecarga leve, 39% apresentaram ansiedade mínima e 73,2% não apresentaram sinais e sintomas de depressão. Correlações negativas foram observadas entre níveis de sobrecarga e a escolaridade materna (p=0,01), presença de sinais e sintomas de ansiedade e recebimento de auxílio financeiro (p<0,04) assim como da presença de sinais e sintomas de ansiedade e ter filhos com histórico de crises convulsivas (p=0,03). Conclusão: apesar do risco iminente de seus filhos serem novamente vítimas de um vírus epidêmico, mães que cuidam de seus filhos com SCZ não apresentaram comprometimento graves na saúde mental.

Neurological outcomes of congenital Zika syndrome in toddlers and preschoolers: a case series.

BACKGROUND: Congenital Zika syndrome causes a spectrum of neurological symptoms with varying effects on function that require different therapeutic strategies. To date, this spectrum of effects and its clinical implications have not been completely described. We describe the neurological examination findings in toddlers and preschoolers, including predominant symptom complexes and comorbidities. METHODS: This study is a case-series neurological evaluation of 75 children with congenital Zika syndrome in Campina Grande, Brazil. The study is part of a cohort of children with congenital Zika syndrome that started in 2015 and is still ongoing. Children with Zika virus infection detected during pregnancy (mothers exhibited rash and were followed and diagnosed by fetal ultrasound abnormalities or RT-PCR) or through microcephaly screening after birth, using Intergrowth 21 guidelines, were selected by laboratory and radiological criteria. Children were examined during a 10-day period in September, 2018, and underwent neurological interview, examination, and assessment of functional outcomes and comorbidities. Children were divided in groups of predominant corticospinal or neuromuscular clinical signs and the associations between these groups and clinical comorbidities were assessed. FINDINGS: All of the children recruited to the study from Nov 29, 2015 to Nov 30, 2017 had imaging correlates of congenital Zika syndrome. Children were assigned to groups depending on the signs exhibited, either corticospinal or neuromuscular, with or without dyskinetic signs. 75 children completed the evaluation, 38 (51%) girls and 37 (49%) boys. Median age was 33 months (range 26-40 months; IQR 29-34). Microcephaly was present at birth in 56 (75%) children, and 19 (25%) children were born with normal head circumference, 15 of whom later developed microcephaly. Neurological examination grouped four children as having isolated dyskinetic signs, 48 children were assigned to the corticospinal group and 23 into the neuromuscular group. Dyskinetic findings were present in 30 (40%) children, either alone (four [5%]) or combined with corticospinal (19 [40%] of 48) or neuromuscular (seven [30%] of 23) findings. Comorbidities were highly prevalent, and the neuromuscular group had worse functional outcomes, evaluated by gross motor function (p=0·026), manual abilities (p=0·0013), and communication function (p<0·0005) classification scales, than the corticospinal group, whereas pneumonia (p<0·0005) and urinary tract infections (p<0·0005) were more frequent in the corticospinal group. Cortical hyperexcitability was supported by several clinical correlates, such as early onset epilepsy, persistence of primitive reflexes, and dystonia. INTERPRETATION: We describe distinct neurological profiles in the congenital Zika syndrome spectrum, with functional outcomes tending to correlate with these groups. The clinical division of children based on the disease signs proposed here is supported by the literature on central and peripheral nervous system pathology in congenital Zika syndrome. The high prevalence of dyskinetic symptoms merits special attention.
