Abstract
Background and purpose The objective of this study is to evaluate the risk of secondary autoimmune diseases in multiple sclerosis (MS) patients treated with alemtuzumab (ALZ) through a meta-analysis. Methods PubMed, Web of Science, OVID, EMBASE, and Cochrane central register of controlled trials were searched. Information and data were screened and extracted by 2 researchers. The obtained data were analyzed using the R software meta package. Quality assessment was conducted using the Newcastle-Ottawa Scale (NOS). The causes of heterogeneity were analyzed using subgroup analysis and sensitivity analysis. Publication bias was evaluated using funnel plots and Egger's test. Results The search retrieved a total of 3530 papers from the databases. After screening, a total of 37 studies were included in the meta-analysis. The analysis results indicate that the pooled incidence rate of overall secondary autoimmune events (SAEs) in the included studies was 0.2824 [0.2348, 0.3300] (I²=94%, p<0.01). The overall incidence of autoimmune thyroid events (ATE) was 0.2257 [0.1810, 0.2703] (I²=94%, p<0.01). Among them, the rate of serious autoimmune thyroid events (SATE) was 0.0541 [0.0396, 0.0687] (I²=0%, p=0.44). The incidence rates of different thyroid events were as follows: Graves' disease (GD), 0.2266 [0.1632, 0.2900] (I²=83%, p<0.01); Hashimoto thyroiditis (HT), 0.0844 [0.0000, 0.2262] (I²=81%, p=0.02); Hashimoto thyroiditis with hypothyroidism (HTwH), 0.0499 [0.0058, 0.0940] (I²=37%, p=0.21); fluctuating thyroid dysfunction (FTD), 0.0219 [0.0015, 0.0424] (I²=0%, p=0.40); transient thyroiditis (TT), 0.0178 [0.0062, 0.0295] (I²=0%, p=0.94). The overall incidence of hematological events was 0.0431 [0.0274, 0.0621] (I²=70%, p<0.01). The incidence rates from high to low were as follows: lymphopenia, 0.0367 [0.0000, 0.0776] (I²=81%, p=0.02); Idiopathic thrombocytopenic purpura (ITP), 0.0258 [0.0199, 0.0323] (I²=25%, p=0.15); Hemolytic anemia (HA), 0.0177 [0.0081, 0.0391] (I²=29%, p=0.23); pancytopenia, 0.0136 [0.0000, 0.0314] (I²=0%, p=0.67); Neutropenia, 0.0081 [0.0000, 0.0183] (I²=0%, p=0.42). After excluding thyroid and hematological diseases, the combined incidence of other related SAEs was 0.0061 [0.0014, 0.0109] (I²=50%, p=0.02). The incidence of each disease ranked from highest to lowest as: skin psoriasis (SP), 0.0430 [0.0000, 0.0929] (I²=0%, p=0.57); alopecia areata (AA), 0.0159 [0.0024, 0.0372] (I²=19%, p=0.29); vitiligo, 0.0134 [0.0044, 0.0223] (I²=0%, p=0.81); inflammatory atrichia (IA), 0.0103 [0.0000, 0.0232] (I²=0%, p=0.43); chronic urticaria (CU), 0.0107 [0.0000, 0.0233] (I²=0%, p=0.60); and nephropathy, 0.0051 [0.0000, 0.0263] (I²=62%, p=0.02). Conclusion The occurrence of secondary autoimmune diseases in patients with MS treated with ALZ is noteworthy, particularly in the form of thyroid events and hematological events. Clinicians should monitor the overall condition of patients promptly for early management and avoid delayed diagnosis and treatment.

Abstract
CONTEXT Treatment with Alemtuzumab (ALZ) in patients with Relapsing-Remitting Multiple Sclerosis (RRMS) is associated with the development of ALZ-induced Graves' disease (GD-ALZ). Some cases may develop associated Graves´ Orbitopathy (GO-ALZ), with possible visual compromise. AIM The aim of this study was to describe the main clinical and biochemical characteristics of GD-ALZ, as well as the clinical course of a case series of GO-ALZ METHODS: This study is a retrospective observational study, carried out in a reference hospital for the care of patients with RRMS in Spain. Cases treated with ALZ in the period 2014-2022 were included. GO-ALZ cases were identified among those with clinical symptoms compatible with thyroid eye disease after initiating ALZ treatment. RESULTS A total of 135 cases, with a mean follow-up of 69.6 months after the first ALZ cycle, were included. The incidence of GD-ALZ was 32.6% (44/135), with a predominance of women (77.3%) and mean age of 41.9 years. The presence of first-degree relatives with hypothyroidism was identified as risk factor for the development of GD-ALZ (adjusted P-value: 0.02). GO-ALZ was diagnosed in 6 cases (incidence: 13.6%), of which 3 had severe clinical forms of GO, requiring anti-IL-6 treatment. A favorable response was reported in all of them, with a significant decrease in disease activity and improvement in proptosis. CONCLUSIONS We report one of the largest cohorts of GD-ALZ and GO-ALZ cases. The diagnosis of these entities should be taken into account in patients treated with Alemtuzumab, given the risk of developing severe clinical forms. In moderate-severe forms of GO-ALZ, drugs with anti-IL-6 activity are a safe and effective option.

Abstract
Autoimmune thyroid disease (AITD) is the most common adverse effect in alemtuzumab (ALZ) treated relapsing-remitting (RR) multiple sclerosis (MS) patients. The objective of this prospective study was to analyze the occurrence, timing of onset, clinical course, and laboratory characteristics of AITD post-ALZ. We evaluated 35 RRMS patients treated with ALZ at a single academic MS center; clinical and laboratory data were collected before ALZ initiation and thereafter quarterly on follow-up with a median of 43.5 months. Seventeen out of 31 patients (54.8%) with no prior history of thyroid dysfunction developed AITD with a mean onset of 19.4 months ± 10.2 (SD) after the first ALZ cycle; Graves' disease (GD) (n = 9); hypothyroidism with positive stimulating thyrotropin receptor antibodies (TRAb) (n = 1); Hashimoto thyroiditis (HT) (n = 6); HT with hypothyroidism (n = 1). Interestingly, seven of nine (77.7%) GD patients showed a fluctuating course. Three out of four patients with preexisting thyroid disease remained stable, whereas one with prior HT and hypothyroidism developed fluctuating GD. All patients with GD commenced antithyroid drugs (ATDs); five continued on "block and replace" treatment; one required radioactive iodine, and one total thyroidectomy. Our analysis showed earlier onset of ALZ-induced AITD in comparison to most other ALZ cohorts; overall, these patients required complex therapeutic approaches of the AITD. We observed a higher rate of fluctuating GD, with earlier onset and lower remission rate than previously reported, which in the majority of patients required prolonged "block and replace" therapy in the minimum dose of each therapeutic agent or more definitive interventions.

Front Neurol 2023; 14:1137665. [PMID: 37006489 PMCID: PMC10061078 DOI: 10.3389/fneur.2023.1137665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Accepted: 02/17/2023] [Indexed: 03/18/2023] Open
Abstract
BackgroundAlemtuzumab (ALZ) is an immune reconstitution therapy for treating relapsing-remitting multiple sclerosis (RRMS). However, ALZ increases the risk of secondary autoimmune diseases (SADs).ObjectiveWe explored whether the detection of autoimmune antibodies (auto-Abs) could predict the development of SADs.MethodsWe included all patients with RRMS in Sweden who initiated ALZ treatment (n = 124, 74 female subjects) from 2009 to 2019. The presence of auto-Abs was determined in plasma samples obtained at the baseline and at 6, 12, and 24 months of follow-up, as well as in a subgroup of patients (n = 51), it was determined in plasma samples obtained at the remaining 3-month intervals up to 24 months. Monthly blood tests, urine tests, and the assessment of clinical symptoms were performed for monitoring safety including that of SADs.ResultsAutoimmune thyroid disease (AITD) developed in 40% of patients, within a median follow-up of 4.5 years. Thyroid auto-Abs were detected in 62% of patients with AITD. The presence of thyrotropin receptor antibodies (TRAbs) at the baseline increased the risk of AITD by 50%. At 24 months, thyroid auto-Abs were detected in 27 patients, and 93% (25/27) developed AITD. Among patients without thyroid auto-Abs, only 30% (15/51) developed AITD (p < 0.0001). In the subgroup of patients (n = 51) with more frequent sampling for auto-Abs, 27 patients developed ALZ-induced AITD, and 19 of them had detectable thyroid auto-Abs prior to the AITD onset, with a median interval of 216 days. Eight patients (6.5%) developed non-thyroid SAD, and none had detectable non-thyroid auto-Abs.ConclusionWe conclude that monitoring thyroid auto-Abs, essentially TRAbs, may improve the surveillance of AITD associated with ALZ treatment. The risk for non-thyroid SADs was low, and monitoring non-thyroid auto-Abs did not seem to provide any additional information for predicting non-thyroid SADs.

Abstract
Background Alemtuzumab is an effective therapy for relapsing multiple sclerosis. Autoimmune thyroid events are a common adverse event. Objective Describe endocrine and multiple sclerosis outcomes over 6 years for alemtuzumab-treated relapsing multiple sclerosis patients in the phase 3 CARE-MS I, II, and extension studies who experienced adverse thyroid events. Methods Endocrine and multiple sclerosis outcomes were evaluated over 6 years. Thyroid event cases, excluding those pre-existing or occurring after Year 6, were adjudicated retrospectively by expert endocrinologists independently of the sponsor and investigators. Results Thyroid events were reported for 378/811 (46.6%) alemtuzumab-treated patients. Following adjudication, endocrinologists reached consensus on 286 cases (75.7%). Of these, 39.5% were adjudicated to Graves' disease, 2.5% Hashimoto's disease switching to hyperthyroidism, 15.4% Hashimoto's disease, 4.9% Graves' disease switching to hypothyroidism, 10.1% transient thyroiditis, and 27.6% with uncertain diagnosis; inclusion of anti-thyroid antibody status reduced the number of uncertain diagnoses. Multiple sclerosis outcomes of those with and without thyroid events were similar. Conclusion Adjudicated thyroid events occurring over 6 years for alemtuzumab-treated relapsing multiple sclerosis patients were primarily autoimmune. Thyroid events were considered manageable and did not affect disease course. Thyroid autoimmunity is a common but manageable adverse event in alemtuzumab-treated relapsing multiple sclerosis patients.ClinicalTrials.gov Registration Numbers: CARE-MS I (NCT00530348); CARE-MS II (NCT00548405); CARE-MS Extension (NCT00930553).

Abstract
OBJECTIVES Graves' disease induced by Alemtuzumab (GD-IA) is one of the most frequently observed adverse events in patients with multiple sclerosis (MS) treated with this drug. The aim of this study is the sequencing and description of these events, along with the identification of the risk factors leading to their development. MATERIALS AND METHODS We conducted a retrospective observational study identifying patients with relapsing-remitting multiple sclerosis (RRMS) and GD-IA, studying their baseline clinical features and variables related to the natural history of the disease. RESULTS A total of 121 participants treated with Alemtuzumab were included, of whom 41 developed GD-IA (33.9%). A higher percentage of first-degree relatives with autoimmune thyroid disease was documented in the subgroup who developed the abovementioned event (14.6% vs 1.5%; p < 0.01). A total of 70.7% of patients diagnosed with GD-IA (n = 29/41) had fluctuations in thyroid function during follow-up, and 24.4% (n = 10/41) required total thyroidectomy for resolution of the condition. In 54.8% of participants diagnosed with GD-IA, a pattern of significant TSH decline was identified in the month prior to diagnosis of the event, with high predictive ability and associated with a more favorable clinical course (fewer weeks to normalization of thyroid function, HR = 8.99; 95% CI [2.11-38.44]; p = 0.0003). CONCLUSION GD-IA has an atypical course compared to classical forms of the disease. The identification of risk factors for the development of the disease before starting treatment with Alemtuzumab and early monitoring of thyroid function once this treatment is initiated prove to be useful strategies in the diagnosis and clinical management of this condition.

Abstract
OBJECTIVE Alemtuzumab-induced autoimmune thyroid events (AIATEs) are the most common adverse effects observed in relapsing-remitting multiple sclerosis (RRMS) patients. This study aims to explore the clinical and biochemical characteristics of such AIATEs, and to examine the risk factors for their occurrence, particularly for the worst clinical phenotype of fluctuating Graves' disease (GD). DESIGN, PATIENTS, MEASUREMENTS We retrospectively analysed a real-life single-centre consecutive series of 57 RRMS patients treated with alemtuzumab whose clinical and biochemical parameters were collected before starting the treatment and then monthly during their follow-up. RESULTS AIATEs developed in 39% of patients a mean 17 months ± 11 after the first cycle of alemtuzumab. The most common AIATEs were GD (64%), followed by Hashimoto's thyroiditis with hypothyroidism (23%), TSH-receptor-antibody (TRAb)-positive hypothyroidism (9%), and silent thyroiditis (4%). GD showed a fluctuating course in 57% of cases. Baseline positivity for anti-thyroperoxidase antibodies, and higher absolute titers of anti-thyroglobulin and anti-thyroperoxidase antibodies correlated significantly with the risk of developing AIATEs, but TRAb positivity did not. Higher TRAb titers at the time of GD being diagnosed correlated strongly with a greater risk of the fluctuating GD phenotype. On ROC curve analysis, we found that a cut-off of 7.3 IU/L could be used to predict the risk of developing a fluctuating GD, with a positive predictive value of 100%. CONCLUSIONS TRAb levels measured with commercial automatic methods at the time of a patient being diagnosed with alemtuzumab-induced GD emerged as a novel biomarker for predicting a fluctuating disease phenotype, with an influence on subsequent therapeutic decisions and patients' follow-up.

Immune reconstitution therapies (IRT), which include antibody-based cell-depleting therapies targeting CD52+ (alemtuzumab) or CD20+ (rituximab, ocrelizumab) leukocytes, are approved for the treatment of multiple sclerosis. Thyroid autoimmunity is a common adverse effect of alemtuzumab treatment, Graves' disease (GD) being the most prevalent manifestation. To date, thyroid autoimmunity events have not been reported with CD20-targeting monoclonal antibodies. Case Report. A 59-year-old woman with primary progressive multiple sclerosis with no prior personal history of thyroid disease or autoimmunity, was diagnosed with GD 6 months following the first ocrelizumab infusion. She was asymptomatic and had no signs of ophthalmopathy. Due to the temporal association of GD diagnosis with ocrelizumab infusion, absence of symptoms and our experience with alemtuzumab-induced GD, we decided for an active surveillance strategy and antithyroid drugs were not started. She underwent spontaneous resolution of hyperthyroidism with thyroid-stimulating hormone (TSH) receptor antibodies (TRAb) negativity and a mild and transitory period of subclinical hypothyroidism, while she continued the biannually ocrelizumab administration schedule. To present date, she has maintained close clinical and biochemical surveillance with normal TSH, free thyroxine (fT4) and free triiodothyronine (fT3) levels and undetectable TRAb. Conclusions. This is the first case of GD reported after ocrelizumab administration. The timing, onset and course of this case is similar to alemtuzumab-induced GD, usually interpreted as an "immune reconstitution syndrome"; however, ocrelizumab cell count depletion is inferior in severity, cell population affected and duration of depletion. This case highlights the importance of pre-screening and follow-up with thyroid function tests in patients treated with ocrelizumab. As a novel therapeutic antibody, further investigation is required to unravel the causes of thyroid autoimmunity.

Abstract
Anti TSH receptor antibodies (TSHrAb) are a family of antibodies with different activity, some of them stimulating thyroid function (TSAb), others with blocking properties (TBAb), it is a common finding that antibodies with different function might coexist in the same patient and can modulate the function of the thyroid. However, most of the labs routinely detect all antibodies binding to the TSH receptor (TRAb, i.e. TSH-receptor antibodies detected by binding assay without definition of functional property). Classical use of TSHr-Ab assay is in Graves' disease where they are tested for diagnostic and prognostic issues; however, they can be used in specific settings of chronic autoimmune thyroiditis (CAT) as well. Aim of the present paper is to highlight these conditions where detection of TSHr-Ab can be of clinical relevance. Prevalence of TSHrAb is different in in the 2 main form of CAT, i.e. classical Hashimoto's thyroiditis and in atrophic thyroiditis, where TBAb play a major role. Simultaneous presence of both TSAb and TBAb in the serum of the same patient might have clinical implication and cause the shift from hyperthyroidism to hypothyroidism and vice versa. Evaluation of TRAb is recommended in case of patients with Thyroid Associated Orbitopathy not associated with hyperthyroidism. At present, however, the most relevant recommendation for the use of TRAb assay is in patients with CAT secondary to a known agent; in particular, after treatment with alemtuzumab for multiple sclerosis. In conclusion, the routine use of anti-TSH receptor antibodies (either TRAb or TSAb/TBAb) assay cannot be suggested at the present for diagnosis/follow up of patients affected by CAT; there are, however, several conditions where their detection can be clinically relevant.

Abstract
Background Pretibial myxedema (PTM) is a local mucinous dermopathy associated with thyroid diseases. Since the etiology of PTM is unclear, the aim of this study is to identify the risk factors for PTM and their etiological roles in PTM occurrence. Methods A large-scale case-control study (n = 1,200) was performed to identify risk factors for PTM by calculating odds ratio (OR) values and 95% confidential intervals. The PTM group entered a glucocorticoid treatment trial. Patients with complete response were followed up to the first relapse in a cohort study. The relative risk (RR) values of the main risk factors were calculated for PTM relapse to test their etiological roles. Results Among the 19 factors, six risk factors were identified: thyroid-stimulating hormone (TSH) receptor antibody (TRAb) (OR 42.93), autoimmune thyroid disease (AITD) or AITD history (OR 10.30), local trauma (OR 6.55), venous stasis posture (OR 6.16), cigarette smoking (OR 4.48), and age (OR 1.05). Serum TRAb levels were positively correlated with the severity of PTM. Of note, 371/400 patients received glucocorticoid treatment, and 330 achieved complete response. The serum TRAb levels after treatment decreased dramatically compared with those before treatment. After stopping glucocorticoid treatment, serum TRAb levels increased significantly when PTM relapsed (P < 0.001). In 165 relapse cases, an increase in serum TRAb levels occurred first, followed by persistent venous stasis posture or local trauma and finally PTM. The RR of elevated serum TRAb levels was 6.73 in PTM relapse cases. In the elevated serum TRAb level group, the RRs of local trauma, venous stasis posture, and local trauma plus venous stasis posture were 8.81, 6.5, and 8.84, respectively, for PTM relapse cases. Conclusions TSHR autoimmunity and local factors in the six identified risk factors are the main causes of PTM occurrence.

Abstract
Background Autoimmune thyroid disease (AITD) occurs in 40%–50% of alemtuzumab-treated persons with
multiple sclerosis (pwMS), most of whom will develop Graves’ Disease (GD). Objective To explore contributory factors for alemtuzumab-related AITD in pwMS. Methods A retrospective patient chart review was performed. Results Sixteen out of 52 (30.8%) pwMS developed AITD. GD occurred in 56.3%
(n = 9), the majority (n = 7, 77.8%) symptomatic. All
but one (85.7%) pwMS with symptomatic GD developed atypical, large and rapid
fluctuations in thyroid hormone levels unexplained by effect of anti-thyroid medication
alone. All symptomatic GD cases were age ≤32 years when starting alemtuzumab (ɸ = 0.60,
p = 0.03). PwMS who started alemtuzumab at a younger age developed
thyroid disease earlier (r = 0.51, p = 0.04). PwMS
with clinical and radiological evidence of brainstem involvement at onset of multiple
sclerosis were 11 times more likely to develop symptomatic GD compared with those with
other phenotypes (p < 0.01). Conclusion Alemtuzumab-induced reconstitution GD may result from early and increased
cross-reactivity between antigens common to the brainstem and thyroid, or presence of
shared Human Leukocyte Antigen (HLA) alleles that determine brainstem and thyroid
involvement. We suggest cautious use of alemtuzumab in younger (≤32 years) pwMS with
early brainstem involvement, especially those actively planning pregnancy, where
alternative therapies are readily available.

Abstract
PURPOSE Autoimmune thyroid events (ATEs) are common side effects after alemtuzumab (ALZ) therapy in patients with multiple sclerosis (MS). Our purpose was to reach more robust evidence on prevalence and outcome of the spectrum of alemtuzumab-induced autoimmune thyroid events in patients with multiple sclerosis. METHODS PubMed and Scopus were systematically searched through July 2019. Studies dealing with patients without personal history of thyroid dysfunctions and affected by MS treated with ALZ and reporting ATEs were selected. Data on prevalence and outcome of ATEs were extracted. A proportion of meta-analysis with random-effects model was performed. RESULTS Considering the overall pooled number of 1362 MS patients treated with ALZ (seven included studies), a 33% prevalence of newly diagnosed ATEs was recorded. Among all ATEs, Graves' disease (GD) was the most represented [63% of cases, 95% confidence interval (CI) 52-74%], followed by Hashimoto thyroiditis (15%, 95% CI 10-22%). Interestingly, GD showed a fluctuating course in 15% of cases (95% CI 8-25%). Of all GD, 12% (95% CI 2-42%) likely had spontaneous remission, 56% (95% CI 34-76%) required only antithyroid drugs, 22% (95% CI 13-32%) needed additional RAI, and 11% (95% CI 0.9-29%) underwent definitive surgery. CONCLUSION Among different categories of ATEs, Graves' hyperthyroidism was the most common thyroid dysfunction, occurring in more than half of cases. Antithyroid drugs should represent the first-line treatment for ALZ-induced GD patients. However, alemtuzumab-induced GD could not be considered as having a more favourable outcome than conventional GD, given the substantial chance to encounter a fluctuating and unpredictable course.

Abstract
BACKGROUND Alemtuzumab is approved for the treatment of active relapsing-remitting multiple sclerosis (RRMS). Alemtuzumab-related secondary autoimmune disorders (sAID) are common, with thyroid sAID being the most frequent, and fundamentally affect the risk-benefit ratio. Therefore, biomarkers indicating the development of sAID are urgently needed to instruct clinical decisions. METHODS We evaluated whether the anti-thyroid autoantibodies (ThyAb) anti-thyroglobulin (anti-TG) and anti-thyroid-peroxidase (anti-TPO) detected at baseline by standard testing are able to indicate increased risk for thyroid sAID following alemtuzumab treatment in a multicentre prospective cohort of 106 alemtuzumab-treated RRMS patients. We here present an interim-analysis with a median follow-up of 36 months. FINDINGS Baseline characteristics demonstrated no significant differences between patients with or without thyroid sAID. 29/106 (27·4%) patients developed thyroid sAID between 5 and 51 months following alemtuzumab treatment initiation. 14/29 patients (48·3%) were positive for ThyAb at baseline and developed thyroid sAID. Hazard ratio for time to thyroid autoimmunity was 12.15 (95% CI 4.73-31.2) indicating a highly increased risk for ThyAb positive patients. Baseline ThyAb were associated with shorter time to sAID, but not with a specific disease entity of thyroid sAID. Hazard ratios for age, sex, previous treatment, disease duration, disability and smoking status demonstrated no significant association with thyroid autoimmunity. INTERPRETATION Standard ThyAb-testing for anti-TPO and anti-TG antibodies at baseline was able to indicate increased risk for clinically manifest thyroid sAID and should therefore be used in clinical decisions concerning alemtuzumab treatment initiation.

Abstract
Thyroid dysfunction (TD) frequently occurs as an autoimmune complication of immune reconstitution therapy (IRT), especially in individuals with multiple sclerosis treated with alemtuzumab, a pan-lymphocyte depleting drug with subsequent recovery of immune cell numbers. Less frequently, TD is triggered by highly active antiretroviral therapy (HAART) in patients infected with human immunodeficiency virus (HIV), or patients undergoing bone-marrow/hematopoietic-stem-cell transplantation (BMT/HSCT). In both alemtuzumab-induced TD and HIV/HAART patients, the commonest disorder is Graves' disease (GD), followed by hypothyroidism and thyroiditis; Graves' orbitopathy is observed in some GD patients. On the contrary, GD is rare post-BMT/HSCT, where hypothyroidism predominates probably as a consequence of the associated radiation damage. In alemtuzumab-induced TD, the autoantibodies against the thyrotropin receptor (TRAb) play a major role, and 2 main aspects distinguish this condition from the spontaneous form: (1) up to 20% of GD cases exhibit a fluctuating course, with alternating phases of hyper- and hypothyroidism, due to the coexistence of TRAb with stimulating and blocking function; (2) TRAb are also positive in about 70% of hypothyroid patients, with blocking TRAb responsible for nearly half of the cases. The present guidelines will provide up-to-date recommendations and suggestions dedicated to all phases of IRT-induced TD: (1) screening before IRT (recommendations 1-3); (2) monitoring during/after IRT (recommendations 4-7); (3) management of TD post-IRT (recommendations 8-17). The clinical management of IRT-induced TD, and in particular GD, can be challenging. In these guidelines, we propose a summary algorithm which has particular utility for nonspecialist physicians and which is tailored toward management of alemtuzumab-induced TD. However, we recommend prompt referral to specialist endocrinology services following diagnosis of any IRT-induced TD diagnosis, and in particular for pregnant women and those considering pregnancy.

Abstract
The association between breast cancer and benign thyroid disorders, in particular thyroid autoimmunity, has been debated for decades. Autoantibodies to thyroid peroxidase, the hallmark of thyroid autoimmunity, have a higher prevalence among patients with breast cancer compared with the general population. Furthermore a correlation between their positivity and a better prognosis of breast cancer was found in several independent small-scale studies, even if such observation was not confirmed in a subsequent retrospective study conducted on the largest patient cohort to date. The thyroid and mammary glands present several biological similarities, therefore the hypothesis of an immune response to shared thyroid/breast antigens could in part explain the association between thyroid autoimmunity and breast cancer. The sodium iodide symporter is expressed in both glands, however it seems unlikely to be the key common antigen, considering that autoantibodies targeting it are rare. Instead thyroid peroxidase, one of the major thyroid autoantigens, is also expressed in breast tissue and therefore represents the main antigenic link between thyroid autoimmunity and breast cancer. Furthermore lactoperoxidase, an enzyme of the same family that shares structural similarities with thyroid peroxidase, is expressed in neoplastic breast cells and is responsible for the cross-reactivity with some autoantibodies to thyroid peroxidase. Novel strategies for the diagnosis and treatment of breast cancer might take advantage of the antigenic link between thyroid and breast tissues.

Abstract
Alemtuzumab-a monoclonal antibody targeting the CD52 glycoprotein expressed by most mature leucocytes-effectively decreases relapse rate and disability progression in early, relapsing-remitting multiple sclerosis (MS). However, secondary autoimmune disorders complicate therapy in nearly 50% of treated patients, with Graves' disease being the most common. Rarely, thyroid eye disease (TED) ensues; only seven such cases have been reported. Our aim was to analyse the largest series of MS patients developing thyroid eye disease after alemtuzumab treatment. We performed a retrospective chart review of MS patients treated with alemtuzumab (1995-2018) and subsequently identified by their treating physicians as having developed TED and referred to our ophthalmology service. As an original trial centre for alemtuzumab, our hospital has treated approximately 162 MS patients with this novel therapy. In total, 71 (44%) developed thyroid dysfunction, most of whom (87%) developed Graves' disease, with ten (16%) referred for ophthalmological evaluation. Two developed active orbitopathy following radioiodine treatment; one occurred after cessation of anti-thyroid drug treatment. Three developed sight-threatening disease requiring systemic immunosuppression, with one refractory to multiple immunosuppressants. The remaining patients were treated conservatively. TSH-receptor antibody (TRAb) levels were significantly raised in all cases, when ascertained. We report sight-threatening as well as mild TED in MS patients after treatment with alemtuzumab. Endocrine instability, radioiodine treatment and positive TRAb are all likely risk factors. The data support at least 6-monthly biochemical and clinical assessment with a low threshold for referral to an ophthalmologist, particularly for those with higher TRAb levels who may be at greater risk of orbitopathy.

Abstract
I was privileged to be one of the co-chairs, along with Professor Tim Sullivan (Brisbane, Australia), for the Cambridge Ophthalmological Society (COS) annual international symposium, which, this year, was dedicated to thyroid eye disease (TED). Together with the organisers, Miss Rachna Murthy and Professor Keith Martin from COS, we compiled an impressive programme covering all aspects of the condition from events happening in a single orbital cell to improved surgical approaches.
