RESUMEN

Gender incongruence and the number of people seeking gender affirming hormone treatment has dramatically risen in the last two decades. In the UK, transgender women and non-binary transfeminine individuals are typically treated with simultaneous suppression of endogenous testosterone production through anti-androgens and exogenous oestradiol replacement. Oestrogen replacement comes in different forms and is primarily given as transdermal (gel or patch) or oral preparations in the UK. Decisions around preparation choice are based on a combination of individual preference and/or mitigating the chance of complications based on individual risk profiles. Time frames to achieve female physical changes are largely predictable and managing expectations of individuals prior to commencing treatment is highly important. Common complications include venous thromboembolism, liver dysfunction and effects on fertility, thus individuals should be thoroughly counselled prior to commencing treatment. This article provides an overview of the management and considerations of gender-affirming hormone treatment in transgender women and non-binary transfeminine individuals.

RESUMEN

Cardiovascular complications remain the leading cause of morbidity and mortality in individuals with diabetes, driven by interlinked metabolic, inflammatory, and thrombotic changes. Hyperglycaemia, insulin resistance/deficiency, dyslipidaemia, and associated oxidative stress have been linked to abnormal platelet function leading to hyperactivity, and thus increasing vascular thrombotic risk. However, emerging evidence suggests platelets also contribute to low-grade inflammation and additionally possess the ability to interact with circulating immune cells, further driving vascular thrombo-inflammatory pathways. This narrative review highlights the role of platelets in inflammatory and immune processes beyond typical thrombotic effects and the impact these mechanisms have on cardiovascular disease in diabetes. We discuss pathways for platelet-induced inflammation and how platelet reprogramming in diabetes contributes to the high cardiovascular risk that characterises this population. Fully understanding the mechanistic pathways for platelet-induced vascular pathology will allow for the development of more effective management strategies that deal with the causes rather than the consequences of platelet function abnormalities in diabetes.

RESUMEN

BACKGROUND: The enhanced thrombotic milieu in diabetes contributes to increased risk of vascular events. Aspirin, a key antiplatelet agent, has inconsistent effects on outcomes in diabetes and the best dosing regimen remains unclear. This work investigated effects of aspirin dose and interaction with glycaemia on both the cellular and protein components of thrombosis. METHODS: A total of 48 participants with type 1 diabetes and 48 healthy controls were randomised to receive aspirin 75 or 300 mg once-daily (OD) in an open-label crossover study. Light transmittance aggregometry and fibrin clot studies were performed before and at the end of each treatment period. RESULTS: Aspirin demonstrated reduced inhibition of collagen-induced platelet aggregation (PA) in participants with diabetes compared with controls, although the higher dose showed better efficacy. Higher aspirin dose facilitated clot lysis in controls but not individuals with diabetes. Collagen-induced PA correlated with glycaemic control, those in the top HbA1c tertile having a lesser inhibitory effect of aspirin. Threshold analysis suggested HbA1c levels of > 65 mmol/mol and > 70 mmol/mol were associated with poor aspirin response to 75 and 300 mg daily doses, respectively. Higher HbA1c was also associated with longer fibrin clot lysis time. CONCLUSIONS: Patients with diabetes respond differently to the antiplatelet and profibrinolytic effects of aspirin compared with controls. In particular, those with elevated HbA1c have reduced inhibition of PA with aspirin. Our findings indicate that reducing glucose levels improves the anti-thrombotic action of aspirin in diabetes, which may have future clinical implications.

RESUMEN

BACKGROUND: Therapeutic drug monitoring (TDM) of infliximab (IFX) trough levels and anti-drug antibodies in conjunction with symptoms, disease history, and investigations can aid decision-making. This study evaluated 1-year outcomes of patients with decisions that were altered on the basis of TDM results, in order to investigate whether outcomes from TDM-based decisions to adjust or stop IFX treatment are durable. METHODS: We retrospectively collected clinical outcomes 12 months post treatment decisions based on proactive TDM. Patients whose initial treatment decisions were altered on the basis of TDM results were compared with those where the decision remained unchanged. Events of interest were inpatient admissions with active inflammatory bowel disease (IBD), further changes to biologic therapy, and IBD-related health-care costs. RESULTS: Of 189 patients, 54 (28%) had initial treatment decisions altered in the light of TDM results. The 135 patients whose initial decision was not altered in light of TDM results served as the comparator. There were no differences in hospitalization rates or subsequent biologic switches between the altered decision groups and the comparator group. IBD-related health-care costs were higher in those whose initial decision was altered (median GBP 7,912 vs. GBP 6,521; p < 0.0001) due to higher drug costs (median GBP 7,062 vs. GBP 6,012; p < 0.0001). CONCLUSION: Our study demonstrates good outcomes from changes to IFX treatment based on TDM. Patients with a decision to stop, switch, or continue with an adjusted IFX dose experienced comparable clinical outcomes but had higher drug-related expenditure than those whose treatment decision was not altered in light of TDM.

RESUMEN

Type 2 diabetes mellitus (T2DM) has an ever-growing prevalence worldwide, affecting 1 in 11 adults. It continues to significantly impact patients in terms of morbidity and mortality, in addition to impairing quality of life while adding to the spiralling healthcare costs. Metformin was first used over half a century ago, and for the past two decades, it has been considered first-line oral therapy to treat patients with T2DM, in whom lifestyle measures failed to improve glycaemic control. Early landmark studies supported a glycaemic benefit with metformin use with a relatively safe adverse effect profile, particularly with avoidance of hypoglycaemia. Moreover, studies have indicated other potential beneficial role for metformin on organs typically affected by diabetes complications. However, more recently, with the discovery of newer hypoglycaemic agents and the wealth of data provided by large-scale cardiovascular safety studies, algorithms for the treatment of patients with T2DM have become increasingly complex. Indeed, recent guidelines challenge current thinking and advocate the use of agents other than metformin as first-line agents in those with higher cardiovascular risk, potentially unseating metformin from its long-held throne. This narrative review aims to summarize the background and origins of metformin, assess its role in the current management of patients with T2DM, highlighting the clinical efficacy and safety profile of this agent. Also, the position of metformin in the clinical algorithms is discussed in light of the most recent evidence in the field, helping with an ever-increasing shift towards individualized patient care to maximize benefits and minimize risks.

RESUMEN

OBJECTIVE: Patients with rheumatic diseases are often treated with prolonged, high-dose systemic glucocorticoids which can cause hypothalamic-pituitary-adrenal (HPA) axis suppression and development of tertiary adrenal insufficiency. Adrenal insufficiency carries the risk of serious, potentially life-threatening adrenal crisis. Our study evaluated the prevalence, characteristics and recovery of patients with underlying rheumatology conditions who had received prolonged glucocorticoid treatment. DESIGN AND PATIENTS: Retrospective, cross-sectional study. We evaluated 238 patients seen in outpatient rheumatology clinic, managed in accordance with current nationally and internationally accepted clinical guidelines. MEASUREMENTS: Data collected included patient demographics, historical steroid data, 09.00 h cortisol/short synacthen test (SST) results and follow-up data on those with repeat assessments. RESULTS: Overall, 65% of our cohort had a 09.00 h cortisol <350 nmol/L. On SST, 43% of patients demonstrated evidence of possible tertiary adrenal insufficiency. Prednisolone equivalent dose at time of SST was significantly higher in the group who failed SST vs. those who passed; mean of 5.57 mg vs. 3.59mg (p = .005). 09.00 h cortisol result correlated with 30-min cortisol on SST (R2  = .20, p = .002). 0-min cortisol on SST correlated more strongly with 30-min cortisol than 09.00 h cortisol (R2  = .59, p-value < .001). Patients with 0-min cortisol >350 nmol/L, all passed their SST. Patients who remained on prednisolone were more likely to recover (71%) vs. those switched to hydrocortisone (27%), P = .02. Peak steroid dose was predictive of recovery; significantly lower in those who recovered (mean of 22.3 mg vs. 33.8 mg, P = .03). Steroid duration was not found to be a predictor of recovery [recovery (64.2 months) vs. non-recovery (55.6 months), P = .58]. There was no correlation found to outcome on SST with age, sex, peak steroid dose, steroid duration, underlying rheumatological condition, additional exogenous steroid use or serum sodium. CONCLUSIONS: Forty three percent of our patients demonstrated sub-optimal adrenal function on SST. Steroid dose at the time of SST was the only significant predictive risk factor for tertiary adrenal insufficiency. 09.00 h cortisol demonstrated good correlation with outcome on SST and could represent a valid screening test to reduce need for SST if 09.00 h >350 nmol/L. Further prospective data are required to further characterize risk factors, predictive features of recovery and establish optimal management strategy of steroids (prednisolone vs hydrocortisone) to encourage adrenal recovery.

RESUMEN

BACKGROUND: Smoking has a detrimental effect on Crohn's disease (CD) while data on ulcerative colitis (UC) are conflicting. Smoking habits have changed dramatically in the UK due to a public smoking ban and the advent of e-cigarettes. We describe current smoking rates in patients with inflammatory bowel disease (IBD) and any effects on disease course. METHODS: Self-reported smoking status was elicited in outpatients with IBD, and clinical data were extracted from patient records. RESULTS: Of 465 patients (58% CD, 42% UC), 247 (53.1%) were ever-smokers (37.4% ex-smokers, 15.7% current smokers). Electronic cigarettes (e-cigarettes) were ever used by 28 patients (15 current users). All e-cigarette users had previously smoked cigarettes and 13 had stopped smoking completely. Patients with CD were more likely to currently smoke (21.5% vs 7.7%, p<0.001) than those with UC. Ever use of biological therapy was higher in current smokers compared with never smokers (49% vs 35%, p=0.034). The need for surgery was higher in current smokers compared with never smokers (43% vs 25%, p=0.006). The risk of CD complications during 21-month prospective follow-up was numerically higher for current smoker versus e-cigarette users (53% vs 17%, p=0.19).Compared with the general population, the proportion of current cigarette smokers (14.9% vs 15.1%) and e-cigarette users was similar in our cohort (4.26% vs 5.5%). CONCLUSIONS: Patients with IBD show similar smoking behaviour to the general population. E-cigarettes were used as replacement for cigarettes or by some as an intermediate step for smoking cessation. Larger, prospective studies are required to fully determine the effects of e-cigarettes on IBD.

RESUMEN

INTRODUCTION: Fatigue is a frequent, debilitating symptom of inflammatory bowel disease (IBD). Despite this, studies report dissatisfaction among IBD patients regarding how little attention is given to fatigue-related issues during consultations. We performed a pilot randomized controlled trial (RCT) to assess whether a brief, structured, multidisciplinary psychological support program improved fatigue, mood and quality of life indices in patients with quiescent IBD. METHODS: The intervention consisted of three small-group psychoeducational sessions over 6 months. Primary outcomes were effect on fatigue severity and impact scores. Secondary outcomes included effect on depression, anxiety, somatization scores, generic and disease-specific quality of life. RESULTS: Twenty-three patients were enrolled, 10 in the intervention arm and 13 controls. Mean fatigue severity and impact scores improved for patients in the intervention group (by 14.5-13.1 and 49.7-45.8, respectively), and worsened in controls (by 11.5-12.6 and 33.5-35 respectively). Mean Short Form 36 (SF-36) scores for role limitations due to physical health decreased from 44.4 to 38.9 in the intervention group, but increased from 44.2 to 51.9 among controls. Energy scores in the intervention group improved from 17.8 to 26.6, but only from 31.4 to 31.7 among controls. Short IBD questionnaire scores improved in both groups, from 46.2 to 45.2 in controls compared with 44.4-40 in the intervention group. DISCUSSION: In this small pilot RCT, positive effects were demonstrated on fatigue, energy levels and other quality of life outcomes. Larger, adequately powered studies with longer follow up are required.ClincialTrials.gov identifier: NCT02709434.
