  • Calcineurin inhibitors tacrolimus and Cyclosporine A in the treatment of Henoch- Schönlein Purpura in children

    I read with great interest the article titled “Off-label use of tacrolimus in children with Henoch-Schönlein purpura nephritis: a pilot study” by Zhang et al.(1). To my great astonishment the authors did not discuss any of the studies published on the use of another calcineurin inhibitor Cyclosporine A (CyA)  in the treatment of Henoch Schönlein purpura in children.

    In the first chapter of the discussion section they refer to our report where we compared methylprednisolone pulse treatment (MP) and CyA in a randomized trial (2) stating that “Remission was achieved slowly and only in 53% of patients with methylprednisolone” (1).

    I would like to draw the readers´s attention to the fact that in the same paper we showed that another calcineurin inhibitor i.e. CyA was by no means inferior to MP for the treatment of severe HSN (2). Indeed, CyA was even more efficacious than MP, since remission was achieved within 3 months in all CyA-treated patients (N=11) compared to 54% (7/13) in MP group (p=0.016). All the CyA treated patients responded to the treatment with no need for additional immunosuppressive therapy. In contrast, in MP group 6/13 (46%) needed additional immunosuppressive treatment. The remission rates in the MP treated patients were 85% (11/13) and 77% (10/13) after 1 and 2 years, respectively in contrast to 100 % in CyA-treated patients. The renal survival rate in the CyA group was 100%, as against 85% in the...

  • Editor's note

    This study was published online in Archives of Disease in Childhood after peer review in September 2017. The trial tested the effectiveness of a neurolinguistic programming intervention (used widely but never formally tested) in children and young people with chronic fatigue recruited between 2010 and 2013. Though the number of participants was small, analysis suggested a benefit in terms of physical function (measured by the standard SF 36 scale) at both 6 and 12 months after intervention.

    Since publication, the study has been criticised for failing to meet ICMJE and BMJ policy on trial registration and for not fully adhering to CONSORT guidance on trial reporting. The journal has been criticised for not detecting these issues during editorial and peer review. We have acknowledged these comments and reviewed our processes in relation to this paper and relating to EQUATOR guidance in general. In addition, we have received clarifications from the authors which are under editorial consideration.

  • The use of nasal mask continuous positive airway pressure in preterm infants.

    The evidence that nasal mask continuous positive airway pressure (CPAP) is better than bilateral, short nasal prong CPAP is convincing.1 However the evidence of benefit is only for short-term outcomes. I have significant concerns about using nasal mask CPAP continuously over many days in extremely preterm or extremely low birth weight infants. These babies have soft malleable skulls. We saw that this was a problem decades ago when small babies were primarily nursed with their head on the side; and subsequent dolichocephaly was very common as a result.2 The hat and straps needed to keep a mask in place put pressure on a baby's soft, malleable skull in a different way to the hat used during nasal prong CPAP. The long term effects of this pressure on boney development, particularly of the midface, are unknown, but they could be considerable. Because of these concerns I do not use nasal mask CPAP continuously. I alternate the use of masks with nasal prongs.

  • Charlie Gard and the dictates of the heart

    The story of Charlie, like that of the little Alfie, are events on which everything has been said, but without an adequate reflection on some basic principles that concern precisely the respect for life and the quality of care that daily thousands of health workers try to provide terminal patients. We can discuss for a long time what is best for the interest of the individual patient and family, but the value of the scientific method that constitutes the cornerstone of the medical profession can not be ignored.
    Likewise it is the duty of the community to uphold the moral integrity of clinical practice by refusing to provide treatments that do not meet a reasonable scientific justification based on evidence of efficacy. Not thinking according to these principles are also betraying the dictates of the heart and not only those of a reasonable science, which should always be at the service of the patient's good, even in the face of death, in a society that should be defined as "civil".
    If it is true that the heart has its reasons that reason does not know, it is the heart that, in the case of terminal children, makes the best choices.
    He wrote anonymously one of the two hundred health care workers who followed Charlie: "We did not want to lose Charlie, but it was our legal and moral obligation, our job, to become his spokesman when it was time to say enough".

  • Prevention of conflict is better when there is no cure

    I was interested to read the articles in this month’s journal exploring the difficulties of end of life decisions when parents and their doctors cannot agree.(1–3) These articles reflect the global media attention focused upon several recent tragic cases in the UK, where differences in view between parents and the clinical team led to confrontation and an unfolding tragedy in the public arena. Whilst all these articles describe the complexity they offer little in terms of solutions. Is it possible to prevent future cases from degenerating into public dispute, or is it an inevitable consequence of modern medicine? Have we advanced to a point where children that would have succumbed now live, and so the focus of care has shifted towards how they live rather than if they live or die?

    At least part of the solution should be a shift in focus shift toward prevention of conflict in these high stakes clinical areas rather than finding a remedy once conflict has occurred. This is not just about being better at communicating with families. Conflict prevention will require cultural change, the identification of early warning signs and the use of mediation to facilitate communication between parents and doctors at an early stage.

    Communication is not just about what we say, but about how we act and the social networks that we live and work in. It was interesting that there was also an article on Family Integrated Care in the same issue of the journal (4). Patel and colle...

  • Testing in relation to timing of illness needs to be considered

    The authors have added an interesting opportunity to refine our clinical decision making with the addition of a point of care test (POC) . However I would argue that choice of POC test might be a critical factor here and very much dependent on initial onset of symptoms. Some years ago published data on the then relatively new POC test for Procalcitonin (PCT-Q) indicated that children presenting within 24 h, PCT performed significantly better (AUC 0.96, SE 0.05) than CRP (0.74, 0.12).(1) This could well explain the differences the authors found in the primary care arm of their study. Setting for these tests becomes increasingly important as we see a shift of more children being seen in GP run Urgent Care Centres with a possibly a different spectrum of illness severity.(2) Prospective studies in different settings comparing both of these biomarkers as POCs would be worth further cosideration.

  • CRP first? : Less is better for education

    With great interest, I read a recent study by Verakel et al (1). illustrating the utility of a newly developed algorithm for excluding serious infections (SI) in acutely ill children. Their algorithm stratifies patients into three risk groups based on the values of point-of-care C reactive protein (POC CRP) and is meant to assist the decision making of physicians, especially trainees. This method demonstrated excellent diagnostic performance and enabled physicians to rule out 36% of SI in children visiting outpatient clinics and emergency departments. However, their proposed method does raise some concerns about potential negative consequences in the educational context.
    The algorithm requires physicians to perform the POC CRP test for all patients regardless of their pre-test probability of SIs. In addition, their model may lead young physicians to draw conclusions about the patients’ clinical features only after estimating the risk of SI based on the POC CRP value and may cause them to neglect the importance of history taking and physical examinations.
    As the authors state, the POC CRP is an innovative tool in pediatric acute care; a POC sample can be obtained by a simple finger prick and the test results can be obtained within several minutes. Nevertheless, in pediatric practice sometimes “doing nothing” is better than “doing something”. This may well be one of the most important principles in pediatrics (2-4). Our role as senior physicians is to show traine...

  • Authors' reply:

    I would like to thank Professor Mitch Blair for his valuable input and bringing up the issue of considering symptoms onset when interpreting point-of-care test results in acute care settings. Recognizing serious infection in children can be challenging, especially at disease onset when the severity of the infection is unclear. Although the choice of biomarker is pivotal in the risk assessment of acutely ill children guided by the point-of-care test result, we had very good rationale to choose C-reactive protein (CRP) as our preferred test.

    Previous research:
    CRP and procalcitonin were identified as the best inflammatory markers for serious infections in children to date in a systematic review, which only identified studies from hospital settings.[1] A CRP <20mg/L and procalcitonin <0.5ng/mL significantly reduce the risk of missing a serious infection in children. Our recent study on point-of-care (POC) CRP in primary care found an even lower threshold of 5mg/L to rule out serious infection in those children, probably due to the early presentation in primary care, when the inflammatory response is still developing, which indeed confirms the importance of setting.[2]
    However, as shown in Figure 6 of the paper by Van den Bruel et al., C-reactive protein and procalcitonin had comparable diagnostic accuracy in the systematic review, as the shape of the curves was roughly similar and the confidence intervals were largely overlapping.[1]

  • Population-based study of cognitive outcomes in congenital heart defects: Novel Information about a not so uncommon entity

    I read the article with interest and wish to congratulate the authors for their genuine work on a little known subject.
    However there are certain points which require elaboration:
    (a) It is likely that there are independent genetic factors that are responsible for a baby being born SGA and the same factors may be playing a role in affecting cognitive outcomes.These factors have not been addressed in the study.
    (b) Cognitive outcome of a child is the result of certain internal and certain extraneous factors (eg environmental stimulation).The extraneous factors may confound the results of the above study.
    (c) Open heart surgery per se may be detrimental to the cognitive development of a child .But there are certain factors such as Bypass time,duration of mechanical ventilation,exposure to hypotensive milieu,etc that need to be explored in order to get an indepth insight into the subject.
    To summarize, the article is a praiseworthy effort into a novel field which opens up potentials of further avenues of research.

  • Nevere X ray

    Dear Editor,

    We appreciated the paper by McCrossan and others but we believe that the diagnosis of pneumonia in children should be made on a clinical ground and that chest X-rays should be considered only in case of a diagnostic doubt or to rule out a complication such as pleural effusion.[1] A X-ray control after a round pneumonia in adults is prescribed with the aim of ruling out an undelying cancer but this is an extremely rare condition in children. Considering this, rather than discussing the opportunity of a radiologic follow up we should consider the opportunity of adapting international guidelines to children.
