Experiences of parents whose children participated in a longitudinal follow‐up study

BackgroundLong‐term follow‐up is necessary to understand the impact of perinatal interventions. Exploring parents'' motives and experiences in consenting to their children taking part in longitudinal studies and understanding what outcomes are important to families may enhance participation and mitigate the loss to follow‐up. As existing evidence is largely based on investigators'' perspectives using Western samples, the present pilot study explored parents'' perspectives in a multicultural New Zealand context.MethodsData were generated using semi‐structured interviews with parents whose children had participated in a longitudinal study after neonatal recruitment. Parents'' experiences of being part of the study were analysed thematically using an inductive approach.ResultsParents (n = 16) were generally happy with the outcomes measured. Additionally, parents were interested in lifelong goals such as the impact of parental diabetes. We identified three themes: (1) Facilitators: Research participation was aided by motives and parent and research characteristics such as wishing to help others and straightforward recruitment; (2) Barriers: A hesitancy to participate was due to technical and clinical research aspects, participation burden and cultural barriers, such as complex wording, time commitment and nonindigenous research and (3) Benefits: Children and parents experienced advantages such as the opportunity for education.ConclusionsParents reported positive experiences and described the unexpected benefit of increasing families'' health knowledge through participation. Improvements for current follow‐up studies were identified. Different ethnicities reported different experiences and perspectives, which warrants ongoing research, particularly with indigenous research participants.Patient or Public ContributionNo active partnership with parents of patients took place.

Haemophagocytic lymphohistiocytosis and Epstein–Barr virus: a complex relationship with diverse origins,expression and outcomes

Epstein–Barr virus (EBV) is a ubiquitous herpesvirus with rare but severe potential for lymphoproliferative complications. EBV is associated with a variety of presentations of haemophagocytic lymphohistiocytosis (HLH). HLH is a life-threatening hyperinflammatory syndrome that can occur in patients with genetic defects associated with dysregulation of the immune response (familial HLH) or arise in patients with underlying infection or malignancy (non-familial or secondary HLH). EBV can both serve as the incidental trigger of familial HLH or as the driving factor in patients with selective inherited vulnerability (e.g. X-linked lymphoproliferative disease). Alternatively, acute infection can idiosyncratically cause non-neoplastic HLH in patients without inherited predisposition (i.e. secondary HLH), while EBV-associated T/natural killer (NK)-cell lymphoproliferative disorders and lymphomas can cause neoplasia-associated HLH. The present review will discern between EBV-associated familial and non-familial HLH and highlight diagnostic and therapeutic considerations. Non-familial EBV-associated HLH is a major diagnostic dilemma, as it represents a diverse spectrum of disease ranging from highly curable (non-neoplastic EBV-HLH) to indolent but incurable (chronic active EBV) to acutely fatal (systemic EBV-positive T-cell lymphoma of childhood). Increased clinical awareness and understanding of this rare and potentially devastating subset of EBV-related complications is desperately needed to improve survival for patients with neoplasia-associated HLH.     

PENTA guidelines for the use of antiretroviral therapy in paediatric HIV infection. Pediatric European Network for Treatment of AIDS

Objective

To produce European Guidelines for the use of antiretroviral therapy (ART) in HIV‐infected children.

Design

Systematic literature review using Medline, the major antiretroviral conference reports, and IDSA recommendations on guideline production.

Setting

Pediatric European Network for Treatment of AIDS (PENTA) Steering Committee.

Outcome measure

Guidelines have been produced for the use of antiretroviral therapy in HIV‐infected children in Europe. Recommendations on when to start ART and which ART to start, with dosages and a summary of the relevant literature, have been produced.

Conclusions

These guidelines are aimed at assisting paediatricians in Europe with ART prescribing, and provide a more cautious approach to starting therapy than current paediatric USA guidelines.

     

Childhood anaplastic large cell lymphoma has a high incidence of ALK gene rearrangement as determined by immunohistochemical staining and fluorescent in situ hybridisation: a genetic and pathological correlation

Anaplastic large cell lymphoma (ALCL) comprises 10-15% of childhood non-Hodgkin lymphomas (NHL). Systemic ALCL is highly associated with anaplastic lymphoma kinase (ALK) gene translocations with over-expression of ALK protein. We studied ALK rearrangements using fluorescence in situ hybridisation (FISH) and ALK immunohistochemical staining in 43 paediatric systemic ALCLs. FISH (performed on 35 cases) identified a translocation in 29 cases (83%). Immunohistochemistry identified ALK over-expression in 42/43 cases (97%) with the single ALK-negative case demonstrating an ALK rearrangement by FISH, indicating 100% incidence of ALK translocations.     

Rofecoxib as adjunctive therapy for haemophilic arthropathy

Joint haemorrhage and subsequent haemophilic arthropathy are significant complications in haemophilia. The pathophysiology involves inflammation and angiogenesis. Cyclooxygenase-2 (COX-2) inhibitors are anti-inflammatory agents, which have potent anti-inflammatory, anti-angiogenic and analgesic properties yet do not affect platelet function in the manner of traditional non-steroidal anti-inflammatory drugs. These properties make such agents potentially useful as adjunctive therapy in haemophilia. There is only one prior report describing rofecoxib treatment in a single haemophilia patient. Our objectives were to determine the safety and efficacy of rofecoxib in treating acute haemarthrosis, chronic synovitis, target joints and pain. We conducted a retrospective medical record review of patients treated with rofecoxib for acute haemarthrosis, chronic synovitis, target joint or pain. The safety and efficacy of rofecoxib treatment were determined based on subjective patient reports and physical examinations during follow-up clinic visits. A total of 28 patients between 3 and 37 years of age were treated for a total of 42 courses of rofecoxib treatment. All courses were evaluated for safety and 31 for efficacy. Rofecoxib was used for eight acute haemarthrosis, four target joints, seven cases of synovitis and 12 episodes of pain. Efficacy was demonstrated particularly for chronic synovitis and pain and no serious adverse events occurred. This is the largest study to date evaluating COX-2 inhibitors as adjunctive therapy in haemophilia and suggests that these agents may be an important adjunctive therapy in the management of haemophilia.
