RESUMEN

BACKGROUND: Patients with suspected deep vein thrombosis (DVT) are typically referred to the emergency department for immediate evaluation. To enhance efficiency, our hospital implemented a regional, general practitioner (GP)-driven DVT care pathway, deferring diagnostic evaluation to a scheduled outpatient DVT clinic appointment the following day. Patients receive a single dose anticoagulant from their GP to prevent thrombosis progression while awaiting diagnostic workup. This prospective study aimed to evaluate the safety and patient preferences regarding the DVT care pathway and the type of single dose anticoagulant (low-molecular-weight heparin (LMWH) vs. direct oral anticoagulant (DOAC)). METHODS: Patients enrolled in the DVT care pathway between June 2021 and July 2023 were eligible. Until July 2022, LMWH was administered, and thereafter, the protocol recommended DOAC as the single dose anticoagulant. Patients completed questionnaires, incorporating patient-reported outcome and experience measures (PROMs/PREMs), during their DVT clinic visit and after five days. The primary endpoint was bleeding events within 72 h of receiving the single dose anticoagulant. RESULTS: Of 460 included patients, 229 received LMWH and 231 received DOAC as the single dose anticoagulant. DVT was confirmed in 24.8 % of patients. No major or clinically relevant non-major bleeding were reported. LMWH was associated with more minor bleedings (22.3 % vs. DOAC 13.4 %), primarily attributed to injection site hematomas. Patients reported high satisfaction with the DVT care pathway (96.5 %) and generally preferred DOAC over LMWH. CONCLUSION: Deferring diagnostic evaluation for DVT using a single dose of either LMWH or DOAC in a real-world population is deemed safe. Considering practical advantages, patient preferences, and fewer skin hematomas, we favor DOACs as the single dose anticoagulant in this care pathway.

RESUMEN

OBJECTIVE: Due to increased use of computed tomography (CT), prevalence of thyroid and adrenal incidentalomas is rising. Yet, previous studies on the outcomes of diagnostic work-up of incidentalomas are subjected to inclusion bias. Therefore, we aimed to investigate prevalence and outcomes of diagnostic work-up of thyroid and adrenal incidentalomas detected on chest CT in a less selected population of COVID-19 suspected patients. DESIGN: A retrospective, observational cohort study. METHODS: We included all COVID-19 suspected patients who underwent chest CT between March 2020 and March 2021. Radiology reports and medical records were reviewed for the presence and subsequent diagnostic work-up of thyroid and adrenal incidentalomas. RESULTS: A total of 1,992 consecutive COVID-19 patients were included (59.4% male, median age 71 years [IQR: 71-80]). Thyroid and adrenal incidentalomas were identified in 95 (4.8%) and 133 (6.7%) patients, respectively. Higher prevalence was observed with increasing age, among female patients and in patients with malignancy. Forty-four incidentalomas were further analyzed, but no malignancies were found. Only three lesions were hormonally active (1 thyrotoxicosis and 2 mild autonomous cortisol secretion). Diagnostic work-up did not lead to any change in clinical management in 97.7% of the analyzed patients. CONCLUSION: Prevalence rates of thyroid and adrenal incidentalomas on chest CT in a less selected COVID-19 cohort were 4.8% and 6.7%, respectively. Yet, as all incidentalomas turned out to be benign and only three lesions were (mildly) hormonally active, this raises the question whether intensive diagnostic work-up of incidentalomas is necessary in all patients.

RESUMEN

Purpose: Emotional stress is a precipitating factor for Graves disease (GD). However, the influence of stress relief on the course of GD is unknown. Here, we present a series of patients diagnosed with stress-induced GD in whom stress relief alone led to remission of GD. Cases: We report on 11 patients in whom hyperthyroid symptoms started just after severe emotional stress. All patients had suppressed thyroid-stimulating hormone (TSH) levels and elevated free thyroxine (FT4; 22.2-49.5 pmol/L) and TSH-receptor antibody (TRAb; 0.57-40 U/L) levels and were subsequently diagnosed with stress-induced GD. However, all patients declined antithyroid drug treatment. Surprisingly, clinical and biochemical remission was observed in 9 out of 11 patients after 1 to 3 and 2 to 7 months of self-reported stress relief, respectively. Five patients showed long-lasting remission (median follow-up 2.3 years). In 4 patients, remission was initially achieved, but GD relapsed 1 to 4 years afterwards. In 2 patients, treatment with antithyroid drugs was initiated because of rapidly increasing FT4 levels. Baseline FT4 and TRAb levels tended to be higher in patients who did not achieve remission. Furthermore, patients without long-lasting remission were more frequently known to have prior thyroid disease. Conclusion: We report on a series of patients with stress-induced GD in whom stress relief alone led to remission of GD (thus without antithyroid drugs). This may indicate that clinicians could consider stopping antithyroid drug treatment or at least shortening the treatment period after stress relief in patients with stress-induced GD.

RESUMEN

A considerable percentage of the Dutch population has primary hypothyroidism and is therefore lifelong treated with levothyroxine. Recently, Dutch healthcare insurance companies made plans to change their reimbursement policies with regard to levothyroxine. This policy change implies that the healthcare insurer will only reimburse one specific brand of levothyroxine usually the most inexpensive brand with the aim of reducing healthcare costs. The more expensive brands will no longer be reimbursed, forcing patients to switch between brands. However, clinical experience and previous research reveal that substitution between levothyroxine brands can lead to symptoms both with and without changes of serum thyroxine levels. Do the advantages of levothyroxine substitution even outweigh the disadvantages?

RESUMEN

BACKGROUND: Irritable Bowel Syndrome (IBS) is a prevalent, chronic gastrointestinal disorder that imposes a substantial socioeconomic burden. Peppermint oil is a frequently used treatment for IBS, but evidence about cost-effectiveness is lacking. OBJECTIVE: We aimed to assess cost-effectiveness of small-intestinal release peppermint oil versus placebo in IBS patients. METHODS: In a multicenter randomized placebo-controlled trial, cost-effectiveness was evaluated from a societal perspective. The incremental cost-effectiveness ratios (ICERs) were expressed as (1) incremental costs per Quality Adjusted Life Years (QALY), and (2) incremental costs per successfully treated patient, that is per abdominal pain responder (according to FDA definitions), both after an eight-week treatment period with placebo versus peppermint oil. Cost-utility and uncertainty were estimated using non-parametric bootstrapping. Sensitivity analyses were performed. RESULTS: The analysis comprised 126 patients (N = 64 placebo, N = 62 small-intestinal release peppermint oil). Peppermint oil was a dominant treatment compared to placebo in 46% of bootstrap replications. Peppermint oil was also more effective but at higher cost in 31% of replications. The net-benefit acceptability curve showed that peppermint oil has a 56% probability of being cost-effective at a conservative willingness-to-pay threshold of €10.000/QALY. Peppermint oil was also a dominant treatment per additional successfully treated patient according to FDA definitions, that is in 51% of replications. In this case, the acceptability curve showed an 89% probability of being cost-effective. CONCLUSIONS: In patients with IBS, small-intestinal release peppermint oil appears to be a cost-effective treatment although there is uncertainty surrounding the ICER. When using abdominal pain responder as outcome measure for the ICER, peppermint oil has a high probability of being cost-effective. The use of peppermint oil, which is a low-cost treatment, can be justified by the modest QALY gains and slightly higher proportion of abdominal pain responders. More research and long-term data are necessary to confirm the cost-effectiveness of peppermint oil. NCT02716285.

RESUMEN

We report a 74-year-old patient who developed an acute aortic syndrome (AAS) with intramural haematoma (IMH) during treatment with nintedanib, a tyrosine kinase inhibitor. As we suspected a role for nintedanib, this was immediately interrupted. Four months later, a computed tomographic angiography (CTA) showed significant regression of the IMH. Therefore, we state that, when patients use nintedanib and develop acute chest or back pain, diagnostic work-up for AAS should be considered. Furthermore, other risk factors for AAS, such as hypertension, genetic diseases and comedication should be taken into account when prescription of medication of this class is considered.
