Periosteal fixation of the medial and lateral recti for large-angle incomitant exotropia.

PURPOSE: To describe the evolution of a surgical technique for the correction of large-angle incomitant exodeviations. METHODS: Retrospective review of an interventional case series from 2005 to 2019 in a single centre, with analysis of surgical procedure, prism diopter (PD) deviations and complications. RESULTS: Thirty-one patients underwent surgery at an average age of 42 years (range 4-75 years) for minimal medial rectus function, mostly from oculomotor nerve palsy (23/31; 74%). The mean pre-operative exodeviation was 75 PD (range 30-200PD). Sixteen patients (52%) had undergone previous strabismus surgery. Thirty-eight operations were performed in which the medial rectus insertion was anchored to the periosteum of the posterior lacrimal crest via a retrocaruncular transconjunctival approach. The ipsilateral lateral rectus (LR) was disinserted and fixed to lateral orbital tissue in 29/38 (76%) operations, injected with botulinum toxin in 5, recessed in 2 and had already undergone maximal LR recession in 2. In all but the first 8 operations, temporary limbal sutures were passed through the eyelids to maximally adduct the globe post-operatively. At last follow-up (mean 24 months; range 2-130), the mean reduction in exodeviation was 49PD (range 10-80) and overall residual deviation was 26PD (range 80PD base-in to 14PD base-out). The 5 LR toxin procedures had a mean reduction of 22PD (range 10-40). Seven patients had persistent diplopia, one a transient corneal erosion and one caruncle suture exposure 4 years after surgery. CONCLUSION: Large-angle exodeviations can be markedly improved by bi-rectus fixation. This approach is both safe and effective and can be performed in complex patients with multiple previous procedures.

Effectiveness of a brief form of group dialectical behavior therapy for binge-eating disorder: Case series in a routine clinical setting.

OBJECTIVE: While there is evidence to support the use of group dialectical behavior therapy (DBT) in the treatment of binge-eating disorder (BED), treatment is relatively long compared with other evidence-based treatments. This study explored the effectiveness of brief DBT groups for BED, delivered in a routine community setting. METHOD: Eighty-four adults with BED entered 10-week DBT group treatment in a community eating disorders service. In total, 12 groups were conducted. Patients completed measures of eating disorder pathology, anxiety, depression, and emotional eating at the start and end of treatment, and at 1-month follow-up. Frequency of weekly binges was recorded. RESULTS: Outcomes were similar to those of longer versions of DBT, with an attrition rate of 26%, and significant reductions in eating disorder psychopathology and emotional eating by the end of treatment and at follow-up. Over 50% of patients were abstinent from binge eating by Session 4. DISCUSSION: Group DBT delivered in a 10-session format is clinically equivalent to longer versions of the same treatment. Future research is required to explore patterns of change and to demonstrate replicability under controlled conditions, but these findings are promising for the efficient delivery of effective treatment and reducing waiting times.

Group dialectical behavioral therapy for binge-eating disorder: Outcomes from a community case series.

OBJECTIVE: Whilst there is evidence to support the use of group dialectical behavioral therapy (DBT) in the treatment of binge-eating disorder (BED), few studies have reported on its effectiveness when delivered in routine clinical practice. This study addressed this gap by exploring the effectiveness of group DBT for BED when delivered in a community eating disorder service. METHOD: Participants were 56 adults who presented with BED, and were offered a 20-week DBT group. Eight groups were conducted. Measures of eating disorder pathology, anxiety, depression and emotion regulation were completed at start and end of treatment, and one-month follow-up. RESULTS: The attrition rate was 16.1%. Abstinence rates (no objective binges in the previous month) were approximately 60% at the end of treatment and 50% at follow-up. There were significant reductions in eating disorder psychopathology (but not in mood) by end of treatment and improvements were maintained at follow-up. DISCUSSION: Group DBT is an acceptable and effective treatment for adults with BED when delivered in a routine community setting. Findings are broadly comparable with those from research trials. The lack of significant effect on mood suggests that DBT can be effective by teaching new emotion-regulation skills, rather than changing mood per se.

Retinopathy of prematurity treatment in the UK: trends in neonatal anaesthetic support and location of treatment from a national surveillance study.

The aim of this study is to evaluate current anaesthetic practice for retinopathy of prematurity (ROP) interventions in the UK. We collected the data from the 12-month prospective British Ophthalmic Surveillance Unit study carried out in 2013/2014 that were analysed with regard to type of anaesthesia used for primary ROP procedures and the hospital department in which treatment took place. A total of 327 cases of treated ROP from 55 different UK units were reported in the study. Type of anaesthesia used during treatment was available for 324 (99.1%) cases and the treatment location in 316 (96.6%). Overall, 266 (89.3%) laser treatments and 13 (50.0%) of primary intravitreal injections were performed with the neonate intubated, using intravenous sedation (IVS) in 158 (59.4%) and the remainder, under general anaesthesia (GA). Two hundred thirteen (67.4%) of all ROP procedures took place in the neonatal unit. GA was used in 98 (95.1%) of theatre cases compared with 19 (8.9%) of cases treated in the neonatal unit. Three (0.9%) neonates suffered significant respiratory distress during or immediately after laser treatment.Conclusion: This survey suggests that the preference in UK units is to undertake ROP laser treatment in the neonatal unit with the neonate intubated and sedated intravenously. Those babies treated in the operating theatre are more likely to receive GA. In the surveyed year, half of the neonates receiving intravitreal injections as sole primary therapy was intubated; the reason for this could not be elucidated from the responses. Adverse respiratory reactions during or after laser treatment affected fewer than 1% of the neonates in this study. What is Known: • Prior to the introduction of intravitreal anti-VEGF, almost all ROP treatments in the UK were performed under general anaesthetic (GA). • The technique of intravitreal injection is described using topical anaesthesia and was thought to be changing anaesthesia preferences for ROP treatment. What is New: • Half of the neonates receiving primary anti-VEGF injection in the UK were treated under intravenous sedation or GA. • The increasing use of primary anti-VEGF treatment has not influenced trends in anaesthetic practice in the UK since the last review 10 years ago.

Childhood Lensectomy Is Associated with Static and Dynamic Reduction in Schlemm Canal Size: A Biomechanical Hypothesis of Glaucoma after Lensectomy.

PURPOSE: To compare Schlemm canal (SC) and trabecular meshwork (TM) in children with healthy eyes and those with and without glaucoma after lensectomy. DESIGN: Cross-sectional observational study. PARTICIPANTS: Fifty children 4 to 16 years of age with healthy eyes and 48 children who underwent lensectomy (124 healthy and 72 postlensectomy eyes). METHODS: Anterior segment (AS) OCT (Tomey SS-1000 CASIA; Tomey, Nagoya, Japan) of the nasal iridocorneal angle at 2 levels of accommodative effort (2.5 diopters [D] and 15 D). For each parameter and state of accommodation, a random effects model was fitted to estimate differences between healthy eyes and eyes with history of lensectomy. MAIN OUTCOME MEASURES: Dimensions of SC and TM and conventional AS OCT iridocorneal angle measurements. RESULTS: The horizontal diameter of SC and its cross-sectional area (CSA) are significantly smaller in eyes that have undergone lensectomy versus healthy eyes. Accommodative effort increases SC size in healthy eyes, but not in eyes that have undergone lensectomy. CONCLUSIONS: Lensectomy is associated with a reduction in SC size and a loss of physiologic SC dilatation during accommodative effort, which may reflect a reduction in outflow facility and may contribute to the development of glaucoma after lensectomy.

Quality of Life and Functional Vision in Children with Glaucoma.

PURPOSE: To evaluate the effect of glaucoma on functional vision and on vision-related (VR) and health-related (HR) quality of life (QoL) in children up to 16 years of age. DESIGN: Cross-sectional observational study. PARTICIPANTS: One hundred nineteen children 2 to 16 years of age (mean age, 9.4 years; standard deviation [SD], 4.56 years) with glaucoma and their parents. METHODS: Completion of 3 validated instruments for children to assess (1) functional visual ability (FVA) with the Cardiff Visual Ability Questionnaire for Children (CVAQC), (2) VR QoL with the Impact of Vision Impairment for Children (IVI-C), and (3) HR QoL with the Pediatric Quality of Life Inventory (PedsQL) version 4.0. MAIN OUTCOME MEASURES: Cardiff Visual Ability Questionnaire for Children, IVI-C, and PedsQL scores. RESULTS: Scores for FVA, VR QoL, and HR QoL were reduced in children with glaucoma: median CVAQC score, -1.24 (interquartile range [IQR], -2.2 to -0.11; range, -3.00 higher visual ability to +2.80 lower visual ability); mean IVI-C score, 67.3 (SD, 14.4; normal VR QoL, 96); median PedsQL self-report, 78.8 (IQR, 67.4-90.2); parent report, 71.2 (IQR, 55.7-85.8); and family impact score, 74.3 (IQR, 56.9-88.5; normal HR QoL, 100). Psychosocial subscores were lower than physical subscores on the PedsQL. Older children reported less impairment on CVAQC, IVI-C, and PedsQL than younger children. Parents reported greater impact on their child's HR QoL than children reported themselves. CONCLUSIONS: Glaucoma and its management have a marked impact on a child's FVA and QoL. Children with glaucoma report HR QoL scores similar to those described by children with severe congenital cardiac defects, who have undergone liver transplants, or who have acute lymphoblastic leukemia.

Validation of the East London Retinopathy of Prematurity algorithm to detect treatment-warranted retinopathy of prematurity: a cohort study.

AIM: To validate the East London Retinopathy of Prematurity algorithm (EL-ROP) in a cohort of infants at risk of developing retinopathy of prematurity (ROP). METHODS: The EL-ROP algorithm was applied retrospectively to routinely collected data from two tertiary neonatal units in England on infants eligible for ROP screening. The EL-ROP recommendation, to screen or not, was compared with the development of treatment-warranted ROP (TW-ROP) for each infant. The main outcome measures were (1) EL-ROP's sensitivity for predicting the future development of TW-ROP and (2) potential to reduce ROP screening examinations. RESULTS: Data from 568 infants were included in the trial. The median (IQR) birth weight (g) was 875 (704 - 1103) and gestational age (weeks) was 27.0 (25.4 - 29.0). Maternal ethnicity was black (33%) and non-black (67%). 58(10%) developed TW-ROP and in every case this was predicted by the EL-ROP algorithm. It's sensitivity was 100% (95% CI 94-100%) specificity: 44% (95% CI 39-48%) positive predictive value: 17% (95%CI 16-18%), negative predictive value: 100%. CONCLUSIONS: EL-ROP has been validated in a cohort of infants from two tertiary neonatal units in England. Further validation is required before its clinical usefulness can be assessed.

Relationships between maternal ethnicity, gestational age, birth weight, weight gain, and severe retinopathy of prematurity.

OBJECTIVE: To develop an algorithm that allows advanced identification of infants requiring treatment for retinopathy of prematurity (ROP). STUDY DESIGN: A retrospective observational study was performed at 2 tertiary neonatal units serving a multiethnic population in the UK, using data on 929 infants eligible for ROP screening. The relationships between study variables and the risk of developing ROP requiring treatment were analyzed using multiple logistic regression. RESULTS: After applying exclusion criteria, data from 589 infants were analyzed; of these, 57 required laser treatment. The proportion of treated infants was 5.9% of those born to black mothers, 9.39% of those born to white mothers, and 12.8% of those born to Asian mothers (P = .047). Multiple logistic regression showed that gestational age, birth weight, maternal ethnicity, and early weight gain were predictors for the development of ROP requiring treatment, with maternal ethnicity having greater predictive power compared with early weight gain. We developed an algorithm for predicting the development of ROP requiring treatment with sensitivity, specificity, and positive and negative predictive values of 100%, 65.7%, 23.8%, and 100%, respectively. CONCLUSION: Gestational age, birth weight, early weight gain, and maternal ethnicity are important predictors for the development of ROP requiring treatment. In a multiethnic population, an algorithm to predict development of ROP requiring treatment should include maternal ethnicity. If confirmed through prospective studies, this algorithm could reduce the number of opthalmologic examinations performed for ROP screening.

Benchmarking of survival outcomes following Haematopoietic Stem Cell Transplantation (HSCT): an update of the ongoing project of the European Society for Blood and Marrow Transplantation (EBMT) and Joint Accreditation Committee of ISCT and EBMT (JACIE).

From 2016 EBMT and JACIE developed an international risk-adapted benchmarking program of haematopoietic stem cell transplant (HSCT) outcome to provide individual EBMT Centers with a means of quality-assuring the HSCT process and meeting FACT-JACIE accreditation requirements relating to 1-year survival outcomes. Informed by previous experience from Europe, North America and Australasia, the Clinical Outcomes Group (COG) established criteria for patient and Center selection, and a set of key clinical variables within a dedicated statistical model adapted to the capabilities of the EBMT Registry. The first phase of the project was launched in 2019 to test the acceptability of the benchmarking model through assessment of Centers' performance for 1-year data completeness and survival outcomes of autologous and allogeneic HSCT covering 2013-2016. A second phase was delivered in July 2021 covering 2015-2019 and including survival outcomes. Reports of individual Center performance were shared directly with local principal investigators and their responses were assimilated. The experience thus far has supported the feasibility, acceptability and reliability of the system as well as identifying its limitations. We provide a summary of experience and learning so far in this 'work in progress', as well as highlighting future challenges of delivering a modern, robust, data-complete, risk-adapted benchmarking program across new EBMT Registry systems.

Identification of treatment-warranted retinopathy of prematurity by neonatal nurse specialist.

OBJECTIVE: To determine the accuracy in the identification of infants with treatment-warranted retinopathy of prematurity (ROP) by a trained and experienced ROP neonatal nurse specialist compared with skilled ophthalmologists. METHODS: A single-centre, prospective, blinded, agreement study was performed on a cohort of infants undergoing ROP screening. An experienced ROP neonatal nurse specialist obtained retinal images using a wide field digital retinal imaging system (WFDRI) on 127 infants and identified those with treatment-warranted ROP. This interpretation was compared with the interpretation of the same images by skilled ophthalmologists. The accuracy of the ROP nurse specialist's interpretation was assessed for sensitivity and specificity compared with the gold standard interpretation by the ophthalmologists. RESULTS: The ROP nurse specialist performed 345 ROP screens on both eyes of 127 infants. The mean (SD) gestation age (weeks) and birth weight (g) of the infants screened was 26.8 (2.8) and 929 (327), respectively. The nurse specialist correctly identified all 8 infants with treatment-warranted ROP and 118/119 infants without. The sensitivity and specificity (95% CI) of ROP screening episodes were 100% (63% to 100%) and 99.7% (98.4% to 100.0%), respectively. CONCLUSION: A trained and experienced ROP neonatal nurse specialist can correctly identify infants with treatment-warranted ROP using WFDRI. Further work is required to examine the generalisability of this finding and its impact on ROP screening services.

Smoking and strabismus surgery in patients with thyroid eye disease.

OBJECTIVE: To investigate the relationship between smoking status at presentation and the use of strabismus surgery in the management of patients with thyroid eye disease. DESIGN: Retrospective review of a noncomparative series of patients with thyroid eye disease. PARTICIPANTS: All patients with thyroid eye disease under the care of a single consultant at Moorfields Eye Hospital between 1997 and 2002 (inclusive). METHODS: Retrospective review of clinical case notes. MAIN OUTCOME MEASURES: Survival analysis of patients in cohort and the frequency of strabismus surgery in relation to smoking status at ophthalmic presentation. A subanalysis of patients who underwent orbital decompression and those that did not was undertaken. RESULTS: Of 501 patients seen during the study period, 425 (85%) of 501 sets of notes were available for review, and initial smoking status was recorded for 89% (378/425) of patients, of whom approximately one half (196/378; 52%) were active smokers. Of the smokers, 51 (26%) of 196 underwent strabismus surgery, compared with only 19 (14%) of 138 nonsmokers at presentation. When adjusted for age, the hazards ratio of having strabismus surgery during management for smokers at presentation versus nonactive smokers was 2.19. In the group who did not undergo orbital decompression, this hazard ratio increased to 4.86. CONCLUSIONS: Within this thyroid eye disease cohort, the proportion of smokers at presentation was much larger than that of the general population. There was an increased use of strabismus surgery in active smokers at presentation than in nonactive smokers. This finding was independent of the orbital decompression surgery. The results are consistent with those of previous reports of more severe thyroid eye disease in smokers and raise the possibility that smoking cessation early in the disease may reduce the severity of the changes and the number of rehabilitative strabismus operations needed.

The Use of Botulinum Toxin in a Case of Acquired Periodic Alternating Nystagmus.

AIM: To describe a case of acquired Periodic Alternating Nystagmus (PAN) with oscillopsia treated with botulinum toxin injections into four horizontal rectus muscles. METHOD: A 22-year-old woman presented with sudden onset PAN. The only abnormality found following extensive investigations was bilateral superior cerebellar peduncle atrophy on MRI. Various treatment options were discussed, with reasonable response to baclofen, less so to gabapentin. However, she was keen for a longer-term solution without medication-related adverse effects. She was offered weakening of all four horizontal rectus muscles recessions, either with botulinum toxin or surgery, and she opted for the former to simulate the effects of surgery. 2.5 units of Dysport were injected into each horizontal rectus muscle without adverse effect. RESULTS: Off all treatment, Snellen Visual Acuity (VA) was 6/12 in either eye with oscillopsia as a result of the PAN. Post-botulinum toxin VA was 6/5 and 6/6 on the right and left respectively, with both subjective and objective improvement in the nystagmus and oscillopsia. CONCLUSION: Botulinum toxin has an important role in the nystagmus and strabismus clinics. Depending on the circumstances, it may be used as either long term treatment, or for surgical planning to simulate the effects of surgery. In this case, the effects were equivalent to high dose of baclofen and four horizontal rectus muscles recessions, which she underwent when the effects of the botulinum toxin had worn off. Botulinum toxin could be considered as a treatment option in acquired PAN, particularly in women of childbearing age and/or if intolerant or refractory to medical treatment, but ideally not as a long-term treatment option.

Arsenic concentration and speciation of the marine hyperaccumulator whelk Buccinum undatum collected in coastal waters of Northern Britain.

European whelks (Buccinum undatum) have shown to accumulate high levels of arsenic. Since the accumulation process is not well understood it is necessary to gain information about the geographical variability of the arsenic concentration in them. Here we show that the mean arsenic concentrations of the whelks are site specific and vary by a factor of 3.5 in ten different geographical locations. At fishing grounds where whelks exhibited low arsenic concentrations the arsenic concentration increased linearly with size, whereas the whelks with high arsenic levels from a different location showed no correlation. Although the overall arsenic concentration in the whelks differed between 45 and 655 mg kg(-1) d.w., the inorganic arsenic concentration did not exceed 0.4 mg kg(-1) d.w. The main arsenic compound is arsenobetaine, which is widely considered as non-toxic. The exposure to toxic inorganic arsenic when eating whelks cannot be estimated from their size or their total arsenic concentration.

Benchmarking of survival outcomes following haematopoietic stem cell transplantation: A review of existing processes and the introduction of an international system from the European Society for Blood and Marrow Transplantation (EBMT) and the Joint Accreditation Committee of ISCT and EBMT (JACIE).

In many healthcare settings, benchmarking for complex procedures has become a mandatory requirement by competent authorities, regulators, payers and patients to assure clinical performance, cost-effectiveness and safe care of patients. In several countries inside and outside Europe, benchmarking systems have been established for haematopoietic stem cell transplantation (HSCT), but access is not universal. As benchmarking is now integrated into the FACT-JACIE standards, the EBMT and JACIE established a Clinical Outcomes Group (COG) to develop and introduce a universal system accessible across EBMT members. Established systems from seven European countries (United Kingdom, Italy, Belgium, France, Germany, Spain, Switzerland), USA and Australia were appraised, revealing similarities in process, but wide variations in selection criteria and statistical methods. In tandem, the COG developed the first phase of a bespoke risk-adapted international benchmarking model for one-year survival following allogeneic and autologous HSCT based on current capabilities within the EBMT registry core dataset. Data completeness, which has a critical impact on validity of centre comparisons, is also assessed. Ongoing development will include further scientific validation of the model, incorporation of further variables (when appropriate) alongside implementation of systems for clinically meaningful interpretation and governance aiming to maximise acceptance to centres, clinicians, payers and patients across EBMT.

Medical Management of Children With Congenital/Infantile Cataract Associated With Microphthalmia, Microcornea, or Persistent Fetal Vasculature.

PURPOSE: To report the surgical outcomes of children with cataract associated with microphthalmia, microcornea, or persistent fetal vasculature (MMP) and children with isolated cataract. METHODS: The study included 111 children (cataract associated with MMP: n = 25) who underwent cataract surgery at younger than 16 years. Exclusion criteria were duration of follow-up less than 5 years, intraindividual differences in age at surgery, eye disorders other than MMP, secondary cataract, and syndromal diseases. Main outcome measures were proportion of eyes with glaucoma and best corrected visual acuity (BCVA). Both groups were dichotomized by age at surgery (early intervention group: ≤ 48 days). Descriptive analysis was performed throughout. RESULTS: Median age at surgery was 3.9 months for cataract associated with MMP and 23.3 months for isolated cataract. The median (interquartile range [IQR]) duration of follow-up was 95.9 months (range: 76.0 to 154.5 months). In children with bilateral cataract associated with MMP, the proportion of eyes with final BCVA worse than 0.3 logMAR was similar regardless of age at surgery (early intervention: 80%, later intervention: 78%). In bilateral isolated cataract, the proportions were 56% and 33%, respectively. Children with cataract associated with MMP had a high prevalence of glaucoma (28%). Glaucoma prevalence was lower in the later intervention group. CONCLUSIONS: In the presence of MMP, early cataract surgery is associated with a high risk of post-lensectomy glaucoma, but does not offer the benefit of better visual outcomes.

Superior oblique enlargement in thyroid eye disease.

PURPOSE: To determine the extent of superior oblique enlargement in thyroid eye disease (TED) by comparing the cross-sectional superior oblique areas of TED patients with those of unaffected control subjects. METHODS: The medical records of TED patients treated for strabismus from January 2005 to January 2016 were reviewed retrospectively for demographic and surgical data. The cross-sectional superior oblique area was compared to age-matched controls on high-resolution orbital computed tomography (CT) using a standardized protocol. RESULTS: A total of 46 TED patients and 18 controls were included. The mean superior oblique cross-sectional area in TED subjects was 250% larger than in controls (22.88 ± 6.64 mm2 vs 9.32 ± 1.85 mm2. The mean cross-sectional area was >3 standard deviations from the mean of the control group in 96% of TED patients. CONCLUSIONS: Superior oblique enlargement in TED may occur more frequently than generally recognized, challenging the notion that TED is primarily a disease of the rectus muscles.

Optical Coherence Tomography Findings After Childhood Lensectomy.

Purpose: To explore the impact of childhood lensectomy on posterior segment development. Methods: Cross-sectional observational study at children's eye clinics at a tertiary referral center in London, UK. We included 45 children age 4 to 16 years with healthy eyes and 38 who had undergone lensectomy. We acquired posterior segment optical coherence tomography scans of both eyes. We used parametric and nonparametric tests in SPSS24 for the comparison of parameters between groups and within individuals; a P value less than 0.05 was considered significant. The main outcome measures were foveal pit depth and subfoveal choroidal thickness (CT). Secondary outcomes were inner and outer ring CT and photoreceptor layer parameters, macular and peripapillary retinal nerve fiber layer thickness. Results: Foveal pit depth and subfoveal CT are significantly reduced in eyes that have undergone lensectomy compared with nonoperated eyes. Inner ring CT and outer ring CT are reduced. Foveal inner retinal layer thickness is increased. Mean inner retinal and outer nuclear layer thickness are not affected. Conclusions: Childhood lensectomy is associated with a reduction in developmental foveal pit deepening and lack of developmental thickening of the posterior choroid. Mechanical and optical disruption of foveal and subfoveal choroidal development may affect structural foveal development after childhood lensectomy.

General information for patients and carers considering haematopoietic stem cell transplantation (HSCT) for severe autoimmune diseases (ADs): A position statement from the EBMT Autoimmune Diseases Working Party (ADWP), the EBMT Nurses Group, the EBMT Patient, Family and Donor Committee and the Joint Accreditation Committee of ISCT and EBMT (JACIE).

Over the last 20 years, haematopoietic stem cell transplantation (HSCT) has been used to treat patients with severe autoimmune and inflammatory diseases whose response to standard treatment options has been limited, resulting in a poor long-term prognosis in terms of survival or disability. The vast majority of patients have received autologous HSCT where an increasing evidence-base supports its use in a wide range of autoimmune diseases, particularly relapsing remitting MS, systemic sclerosis and Crohn's disease. Compared with standard treatments for autoimmune diseases, HSCT is associated with greater short-term risks, including a risk of treatment-related mortality and long-term complications. There is a need for a careful appraisal of potential benefits and risks by disease and transplant specialists working closely together with patients and carers to determine individual suitability for HSCT. HSCT should be conducted in accredited transplant centres with robust arrangements for long-term follow-up with both disease and transplant specialists. The aim of this open-access position statement is to provide plainly worded guidance for patients and non-specialist clinicians considering HSCT for an autoimmune disease, especially when treatment abroad is being considered. Recent technical publications in the field have been referenced to support the statement and provide more detail for clinicians advising patients.
