Abstract
OBJECTIVE To derive childhood-onset SLE (cSLE) specific remission definitions for future treat-to-target (T2T) trials, observational studies, and clinical practice. METHODS The cSLE International T2T Task Force conducted Delphi surveys exploring paediatric perspectives on adult-onset SLE remission targets. A modified nominal group technique was used to discuss, refine, and agree on the cSLE remission target criteria. RESULTS The Task Force proposed two definitions of remission: 'cSLE clinical remission on steroids (cCR)' and 'cSLE clinical remission off steroids (cCR-0)'. The common criteria are: (1) Clinical-SLEDAI-2 K = 0; (2) PGA score < 0.5 (0-3 scale); (4) stable antimalarials, immunosuppressive, and biologic therapy (changes due to side-effects, adherence, weight, or when building up to target dose allowed). Criterion (3) in cCR is the prednisolone dose ≤0.1 mg/kg/day (maximum 5 mg/day), whereas in cCR-0 it is zero. CONCLUSIONS cSLE definitions of remission have been proposed, maintaining sufficient alignment with the adult-SLE definition to facilitate life-course research.

Abstract
OBJECTIVE To achieve a consensus-based definition of Low Disease Activity (LDA) for use in cSLE trials. METHODS The International cSLE T2T Task Force, comprising of paediatric rheumatologists/nephrologists, and adult rheumatologists undertook a series of Delphi surveys/consensus meetings to discuss, refine, and vote upon cSLE LDA criteria. RESULTS The Task Force agreed that LDA should be based upon the adult-SLE Lupus Low Disease Activity State definition (LLDAS), with modifications to make it applicable to cSLE (cLLDAS). They agreed upon five cLLDAS criteria: (1) SLE Disease Activity Index (SLEDAI)-2 K ≤4, with no activity in major organ systems; (2) no new features of lupus disease activity compared with the last assessment; (3) Physician Global Assessment score of ≤1 (0-3 scale); (4) prednisolone dose of ≤0.15 mg/kg/day, 7.5 mg/day/maximum; while on (5) stable antimalarials, immunosuppressives, and biologics. CONCLUSIONS A cSLE-appropriate definition of cLLDAS has been generated, maintaining alignment with the adult-SLE definition to promote life-course research.

Abstract
Objective Systemic lupus erythematosus (SLE) features high frequency of cardiovascular disease (CVD) and fluctuating complement levels. The clinical trial Atherosclerosis Prevention in Pediatric Lupus Erythematosus (APPLE) aimed to evaluate whether atorvastatin treatment reduced the progression of atherosclerosis in 221 patients with childhood-onset SLE (cSLE), using carotid intima media thickness (CIMT) as surrogates. We leveraged APPLE biorepository and trial data to investigate the relationship between complement and CVD in cSLE. Methods Gene copy numbers (GCNs) for total C4, C4A and C4B were measured by TaqMan-based real-time PCR and Southern blotting, and analysed with laboratory and clinical parameters through Student's t-test and χ2 analyses. Effects of total C4, C4A and C4B GCNs on the response to placebo or atorvastatin treatment and progression of CIMT were examined by regression analyses. Results At baseline, C4 protein levels strongly correlated with GCNs of total C4 (p=1.8×10-6). Each copy of C4 gene increased mean serum C4 by 3.28 mg/dL. Compared with those without hypertension (N=142), individuals with hypertension demonstrated significantly elevated serum levels for C4 and C3 at baseline and serially (C4: P=5.0×10-25; C3: P=5.84×10-20). Individuals with ≥2 C4B genes had 2.5 times the odds of having hypertension (p=0.016) and higher diastolic blood pressure (p=0.015) compared with those with C4B deficiency. At the study end, subjects with ≥2 C4B and atorvastatin treatment had significantly slower increase in CIMT compared with those treated with placebo (p=0.018). Conclusions cSLE with hypertension had elevated serum levels of C4 and C3 and higher GCN of C4B; cSLE with ≥2 C4B genes would benefit from statins therapy to prevent atherosclerosis.

Abstract
Objectives Autoimmune thrombocytopenia (AITP) and hemolytic anemia (AIHA) are common in childhood-onset systemic lupus erythematosus (cSLE) and may be refractory to conventional therapies. Our objectives were to: (a) examine our experience; (b) determine the rate and durability of response to rituximab; and (c) evaluate its safety in our cSLE population with refractory cytopenias. Methods We performed a single-center retrospective cohort study of cSLE patients with refractory AITP or AIHA treated with rituximab between 2003 and 2012. Outcomes included the time to complete clinical response, time to B-cell depletion, duration of response and time to flare. Adverse events were also analyzed. Results Twenty-four (6%) of 394 cSLE patients received rituximab for refractory cytopenia. The indication was AITP in 16 (67%), AIHA in five (21%) and both in three (13%) patients. The median (interquartile range (IQR)) time from cytopenia onset to rituximab therapy was 16 (7–27) months for AITP and 10 (2–29) months for AIHA. Complete response following the first course of rituximab occurred at a median (IQR) of 48 (14–103) days, only one patient failed to respond. Five (21%) patients had one or more flare episodes at 22 (15–27) months. Infusion reactions were rare and one infection with herpes zoster required hospitalization in the first 12 months. Three of four patients with low IgG levels prior to the first rituximab course developed persistent hypogammaglobulinemia, and three patients have required intravenous immunoglobulin replacement. Conclusion Rituximab appears to be a well-tolerated, safe and long-lasting therapy for cSLE patients with refractory AITP and/or AIHA. Caution should be exercised when considering rituximab for patients with preexisting hypogammaglobulinemia.

Abstract
UNLABELLED Cytomegalovirus (CMV) is a beta-herpesvirus and antibodies to this virus are common in patients with systemic lupus erythematosus (SLE). However, few studies have examined the relationship between CMV infection and SLE. OBJECTIVES Our objectives were: 1) to determine the prevalence of CMV infection at the time of SLE diagnosis, and 2) to determine the risk factors for CMV infection. METHODS A database review of 670 patients with pediatric SLE (pSLE) seen over a 20-year period identified seven patients with a CMV infection detected at the time of diagnosis of SLE. CMV was diagnosed by serology, urine and bronchoalveolar lavage. Clinical manifestations, laboratory findings, virology studies and treatments were reviewed. RESULTS CMV infection was detected in seven patients at the time of SLE diagnosis (1.04% of total cohort): six were female: mean age was 13 years. Predominant features included non-Caucasian ethnicity (p < 0.01 as compared to total SLE cohort), persistent fevers on prednisone in seven and nephrotic syndrome in four. Laboratory findings included: anemia in seven, lymphopenia in five, elevated liver enzymes in four, with anti-dsDNA and anti-RNP antibodies present in six and five, respectively. Six patients received ganciclovir and CMV hyperimmune globulin (Cytogam®) with the continuation of prednisone during CMV treatment. Six of seven fully recovered without sequelae (one without treatment) but one patient died with active CMV infection. CONCLUSIONS There were 1.04% of patients with pSLE who developed CMV infection. All were of non-Caucasian ethnicity. Persistent fever despite prednisone, with concomitant anemia, may be additional clues to CMV infection in pSLE. We suggest all patients have routine testing for CMV immunity at initial presentation of pSLE.

Abstract
OBJECTIVE This study evaluated the effects of obesity on health-related quality of life (HRQOL) measures in juvenile-onset systemic lupus erythematosus (jSLE). METHODS Obesity was defined as a body mass index (BMI) ≥ 95 th percentile according to the Sex-specific Center for Disease Control BMI-For-Age Charts and determined in a multicenter cohort of jSLE patients. In this secondary analysis, the domain and summary scores of the Pediatric Quality of Life (PedsQL) Inventory and the Child Health Questionnaire (CHQ) of obese jSLE patients were compared to those of non-obese jSLE patients as well as historical obese and non-obese healthy controls. Mixed-effects modeling was performed to evaluate the relationship between obesity and HRQOL measures. RESULTS Among the 202 jSLE patients, 25% (n = 51) were obese. Obesity had a significant negative impact on HRQOL in jSLE, even after adjusting for differences in current corticosteroid use, disease activity, disease damage, gender and race between groups. Obese jSLE patients had lower physical functioning compared to non-obese jSLE patients, and to non-obese and obese healthy controls. Compared to their non-obese counterparts, obese jSLE patients also had worse school functioning, more pain, worse social functioning and emotional functioning. Parents of obese jSLE patients worry more. The CHQ scores for obese jSLE patients were also worse compared to non-obese jSLE patients in several other domains. CONCLUSION Our study demonstrates the detrimental effects of obesity on patient-reported outcomes in jSLE. This supports the importance of weight management for the therapeutic plan of jSLE.

Abstract
Background Depressive symptoms are common in adolescence and young adulthood; however, their prevalence in childhood-onset systemic lupus erythematosus (cSLE) is unknown. Objective The objective of this study was to examine the prevalence of depressive symptoms and their association with disease characteristics in children, adolescents, and young adults with cSLE. Methods A cross-sectional sample of patients with cSLE between 10 to 24 years old completed standardized depression inventories. Demographics and disease characteristics were collected. Results Total depression inventory scores reported were below standard cut-off values for depression. However, 26% (10/38) of children and adolescents, and 44% (seven of 16) of young adults had scores at or above established cut-offs for elevated depression symptoms. Physical symptoms of depression were endorsed most frequently. There were no differences in depressive symptoms by disease characteristics including disease duration, health-related quality of life inventory scores, antiphospholipid antibody status, and a history of renal involvement or neuropsychiatric SLE (NPSLE). However, two patients had a history of depression as an NPSLE manifestation of their SLE. In the children and adolescents, prednisone dose was associated with negative self-esteem ( r = 0.37, p = 0.04) and somatic depressive symptoms ( r = 0.39, p = 0.02), but we did not observe a significant association in the young adults. Conclusion Depressive symptoms in cSLE are frequent, although similar to the high prevalence rates in the general population. Physical symptoms are most frequently endorsed. Further study will determine if serial evaluations are recommended for early detection in this at-risk population.

Abstract
The objective of the study was to compare clinical features, treatment and disease outcome in patients with early versus later onset of childhood-onset systemic lupus erythematosus (cSLE). A retrospective matched cohort study of cSLE patients diagnosed between 1988 and 2008 and followed for a minimum of one year was conducted. Thirty-four pre-pubertal cSLE patients with disease onset prior to their 12th birthday were matched by ethnicity and year of diagnosis to 34 pubertal cSLE patients. The most common criteria at diagnosis in both groups were malar rash, arthritis, hematologic manifestations, and renal disease. After a mean follow-up of more than six years, a similar proportion of patients in the two groups were still prescribed corticosteroids (47% and 41%); patients in the early onset group required a significantly higher daily dose (0.6 mg/kg prednisone-equivalent versus 0.2 mg/kg, p < 0.05). There were no significant differences in organ involvement, disease activity and disease damage between the two groups, and severe complications occurred at similar rates. There were a greater number of admissions to the pediatric intensive care unit (PICU) in the early onset group (18 versus 5, p = 0.01), with time-to-event analysis demonstrating a significantly shorter disease duration from diagnosis to first PICU admission in the early onset group ( p < 0.001). While a similar proportion of patients in the early and later onset groups required treatment with cyclophosphamide, patients in the early onset group received treatment earlier in their disease course (mean 13.7 versus 19.9 months, p < 0.001). Early onset cSLE leads to earlier and more frequent PICU admission, earlier use of cyclophosphamide, and higher corticosteroid dose at long-term follow-up.

Abstract
As part of the Atherosclerosis Prevention in Pediatric Lupus Erythematosus (APPLE) Trial, a prospective multicenter cohort of 221 children and adolescents with systemic lupus erythematosus (SLE) (mean age 15.7 years, 83% female) underwent baseline measurement of markers of cardiovascular risk, including fasting levels of high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TG), lipoprotein A (Lpa), homocysteine and high-sensitivity C-reactive protein (hs-CRP). A cross-sectional analysis of the baseline laboratory values and clinical characteristics of this cohort was performed. Univariable relationships between the cardiovascular markers of interest and clinical variables were assessed, followed by multivariable linear regression modeling. Mean levels of LDL, HDL, Lpa, TG, hs-CRP and homocysteine were in the normal or borderline ranges. In multivariable analysis, increased Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), prednisone dose, and hypertension (HTN) were independently associated with higher LDL levels. Higher hs-CRP and creatinine clearance were independently related to lower HDL levels. Higher body mass index (BMI), prednisone dose, and homocysteine levels were independently associated with higher TG levels. Only Hispanic or non-White status predicted higher Lpa levels. Proteinuria, higher TG and lower creatinine clearance were independently associated with higher homocysteine levels, while use of multivitamin with folate predicted lower homocysteine levels. Higher BMI, lower HDL, and longer SLE disease duration, but not SLEDAI, were independently associated with higher hs-CRP levels. The R(2) for these models ranged from 7% to 23%. SLE disease activity as measured by the SLEDAI was associated only with higher LDL levels and not with hs-CRP. Markers of renal injury (HTN, proteinuria, and creatinine clearance) were independently associated with levels of LDL, HDL, and homocysteine, highlighting the importance of renal status in the cardiovascular health of children and adolescents with SLE. Future longitudinal analysis of the APPLE cohort is needed to further examine these relationships.

Abstract
Good multidisciplinary communication is crucial to the safe management of women requiring non-elective Caesarean section. Anaesthetists should participate actively in resuscitation of the fetus in utero; relief of aortocaval compression is paramount. Epidural top-up with levobupivacaine 0.5% is the anaesthetic of choice for women who have been receiving labour epidural analgesia. If epidural top-up fails to provide bilateral light touch anaesthesia from S5 - T5, a combined spinal-epidural technique with small intrathecal dose of local anaesthetic is a useful approach. Pre-eclampsia is not a contra-indication to single-shot spinal anaesthesia, which is the technique of choice for most women presenting for Caesarean section without an epidural catheter in situ. Induction and maintenance doses of drugs for general anaesthesia should not be reduced in the belief that the baby will be harmed. Early postoperative observations are geared towards the detection of overt or covert haemorrhage.

Abstract
A 24-year-old woman with congenital long-QT syndrome (LQTS) required caesarean section at 32 weeks' gestation. Her risk of premature death from malignant ventricular tachyarrhythmias had necessitated implantation of an automatic cardioverter-defibrillator (AICD) with pacemaker capability. The patient expressed a preference for general anaesthesia. To minimise the risk of increased serum catecholamine concentrations and consequent ventricular arrhythmias, an analgesia-based regimen was chosen. With cardioversion, defibrillation, and antitachycardia pacing functions of the AICD selectively deactivated, anaesthesia was induced with bolus doses of thiopentone and remifentanil. Rocuronium was used for neuromuscular block. Anaesthesia was maintained with nitrous oxide and isoflurane, supplemented by a remifentanil infusion. We outline the pathophysiology and treatment of LQTS, and discuss the anaesthetic management of an obstetric patient with the congenital syndrome. This is the first reported case of caesarean section in a patient with an AICD, and the first description of the use of either remifentanil or rocuronium in LQTS.

Abstract
Paediatric patients with systemic lupus erythematosus (SLE) and antiphospholipid antibodies (aPL), specifically lupus anticoagulants (LAC) are at high risk of developing thromboembolic events (TE). Our objectives were to determine the prevalence of TE in paediatric SLE patients with LAC and to determine if anticoagulation was effective to decrease morbidity, and prevent recurrent TE. We reviewed data on 149 paediatric SLE patients treated over 10 years. In all, 24 patients (16%) were LAC positive, and 21 TE occurred in 13 of these LAC positive patients (54% incidence of TE in LAC positive patients). The events were cerebral venous thrombosis (9), arterial stroke (3), deep venous thrombosis (4), pulmonary embolism (2), other venous event (1) and other arterial events (2). The median duration between SLE diagnosis and first TE was 15.2 months (range 0-62), and the median age at first TE was 15.1 years (range 11.4-18.4). Long-term anticoagulation was prescribed, and eight patients (62%) were transferred to adult care on lifelong oral warfarin; four (31%) remain under our care on lifelong warfarin, and one patient died of causes unrelated to her TE. No patient has been identified with deficiencies of protein C, protein S or antithrombin III. One patient is heterozygous for Factor V Leiden, and one is heterozygous for both the Prothrombin 20210A mutation and the MTHFR (methylene tetrahydrofolate reductase) mutation. Four patients had recurrent TE (31%), and three were not anticoagulated at the time of their second event. One patient had two recurrences on therapeutic anticoagulation. Thromboembolic events are prevalent in the LAC positive paediatric SLE population, and consideration for lifelong anticoagulation must occur after an initial TE.

Abstract
Subarachnoid haemorrhage is a leading 'indirect' cause of maternal death in the UK. We describe the case of a 43-year-old woman who presented with headache, photophobia and neck stiffness of sudden onset at 32 weeks' gestation. Cerebral computed tomography demonstrated subarachnoid blood in the cisterns around the midbrain, and oral nimodipine was started to prevent vasospasm. Preparations were made for endovascular coil embolisation in the event of identification of a posterior circulation aneurysm. However, angiography under general anaesthesia failed to reveal any vascular abnormality. On emergence from anaesthesia, headache persisted, and over the next 24 h severe pre-eclampsia developed. Magnesium sulphate was started, and urgent Caesarean section performed under general anaesthesia without incident. The rationale for the neuroradiological, obstetric and anaesthetic management is discussed.

Abstract
Following induction of general anaesthesia for emergency caesarean section the trachea could not be intubated, and ventilation was established only following two cricothyroidotomies. The baby was delivered unimpaired, and tracheostomy subsequently performed. On the intensive care unit, maternal cardiorespiratory variables were satisfactory, although surgical emphysema of the face and neck became apparent. Increasing abdominal distension was relieved by suction to a pelvic drain. Radiographs revealed bilateral pneumothoraces, pneumomediastinum and pneumoperitoneum, which were resolved by intrapleural drainage.

Abstract
BACKGROUND Hypoventilation may occur following induction of anaesthesia with propofol and is potentiated by concurrent use of opioid drugs. This effect is undesirable in patients who will continue to maintain spontaneous respiration during anaesthesia and surgery. The analeptic drug doxapram is known to have selective respiratory stimulatory effects but its action during induction of anaesthesia has been inconsistent. METHOD In a double-blind, placebo-controlled study, the influence of alfentanil pre-treatment on the ventilatory effects of doxapram given during induction of anaesthesia with propofol was studied in 40 patients. Four groups of ten patients (two groups pre-treated with 7 micrograms.kg-1 of alfentanil and two groups with saline) were randomly allocated to receive either 0.5 mg.kg-1 doxapram or saline following infusion of propofol to loss of verbal contact. RESULTS In the groups that received doxapram, minute volumes were significantly increased and end-tidal carbon dioxide concentrations were significantly reduced compared to control groups, although the duration and extent of these effects were less in the group that received alfentanil. Doxapram also reversed an alfentanil-induced reduction in respiratory rate. No adverse cardiovascular or neurological stimulatory effects of doxapram were evident at any time. CONCLUSION We conclude that doxapram 0.5 mg.kg-1 is effective in augmenting ventilation that has been obtunded following induction of anaesthesia with propofol in patients pre-treated with alfentanil.

Abstract
Vasoactive intestinal polypeptide (VIP) and substance P (SP) immunoreactivity are reduced in the cutaneous nerves of diabetic patients with peripheral neuropathy. The functional significance of this finding was studied by measuring the forearm sweat response to intradermal methacholine and the effect of coadministration of VIP and SP in six normal subjects, and in six diabetic patients with neuropathy and eight without. Flare responses to the two peptides were also measured. Methacholine-induced sweat output was significantly greater in neuropathic patients compared with the other groups (p < 0.05), suggesting upper limb denervation supersensitivity. VIP and SP alone did not evoke sweating in any subject. Injection of VIP or SP reduced methacholine-induced sweating to a similar degree in all groups, except that the reduction was smaller in the non-neuropathic group than in the others (p = 0.028 versus normal subjects, p = 0.014 versus neuropathic diabetic patients). Flare responses to the peptides were markedly reduced in the neuropathic patients compared with the other groups (p < 0.01). In neuropathic patients, increased sweat responses and decreased flare coexist with diminished neurophysiological measurements; cutaneous sweating and flare responses provide valuable additional information to conventional methods of neurological assessment in diabetic neuropathy.

Abstract
Anaesthesia was induced in 30 ASA I patients by propofol titrated at 100 mg min-1 to loss of verbal contact, and maintained by infusion of propofol at 10 mg kg-1 h-1 with 100% oxygen. According to randomization, either alfentanil 30 micrograms kg-1 ketamine 1.5 mg kg-1, or 0.9% sodium chloride was injected over 20 s, followed 1 min later by vecuronium 0.08 mg kg-1. Mean arterial pressure and heart rate were measured before and after induction, and 1 and 2 min after analgesic or saline. Onset of neuromuscular block was measured by the evoked hypothenar electromyographic response to train-of-four supra-maximal stimuli at 0.1 Hz. There were significant haemodynamic differences between groups, but mean (SD) times to reduction of T1/control ratios below 95% were 114 (28.0), 106 (19.0) and 128 (34.3) s (P = 0.2, ANOVA). Supplementation of propofol anaesthesia with alfentanil or ketamine does not appear to influence the onset time of vecuronium.

Abstract
Gastric emptying was studied indirectly by paracetamol absorption in 20 patients at 8-12 weeks' gestation and also in 20 non-pregnant controls. Subjects received paracetamol 1.5 g in a tablet with 50 ml of water and remained semi-recumbent for 2 h while venous blood samples were obtained at 15-min intervals. The maximum concentration of paracetamol was significantly lower and the time to maximum concentration significantly greater in pregnant patients. In addition, the areas under the time-concentration curves at 60 and 120 min were significantly smaller in the pregnant group. These changes are indicative of a delay in gastric emptying at 8-12 weeks' gestation.

Abstract
The purpose of this report is to describe a new complication of epidural blood patch for inadvertent dural puncture. A dural tap in an obstetric patient was managed initially with a prophylactic blood patch via the epidural catheter. Despite this, 48 hr later, she developed post-dural puncture headache, neck, and shoulder pain, and was given a second epidural blood patch. This was followed by an immediate and severe exacerbation of her symptoms, which later resolved after the administration of diclofenac. There were no further sequelae. Although severe complications of epidural blood patch are rare, they are alarming. Exacerbation of the original symptoms of post-dural puncture headache caused by, or following, epidural blood patching has not previously been reported.
