Reading the evidence in pharmacology

Drug evidence builds in layers: laboratory pharmacology describes how a compound acts, pharmacokinetic studies describe how the body handles it, and randomized trials test whether it helps and what harms it causes. Post-marketing surveillance and observational studies reveal rarer adverse effects but cannot prove causation. This page is educational and is not a recommendation to start, stop or change any medicine; decisions about treatment belong with a qualified clinician.

Evidence from open-access studies

These open-access studies come from PubMed’s best-match results for this heading (papers whose main topic it is), ranked here by citation count, with one recent addition. Each abstract is reproduced in full under its recorded open licence so that you can read the authors’ own words. They illustrate the literature; they are not a systematic summary of it. Citation counts measure attention, not reliability or clinical benefit.

This retrospective study examines the outcomes of sclerotherapy in children with (veno)lymphatic malformations who received sclerotherapy between 2011 and 2016 (116 children, 234 procedures). Complication severity was classified using the Society of Interventional Radiology classification. Clinical response was rated on a scale of 0 (no change) to 3 (good improvement). The sclerosants used were bleomycin (n = 132; 56%), lauromacrogol (n = 42; 18%), doxycycline (n = 15; 6%), ethanol (n = 12; 5%), or a combination (n = 33; 14%). Four major and 25 minor complications occurred without significant differences between the agents. The median response rate per procedure was 2-some improvement-for all sclerosants. However, in pure LMs (67%), bleomycin and a combination of agents resulted in the best clinical response. On patient level, all had some or good clinical response. Mixed macrocystic and microcystic lesions showed a significantly lower clinical response (median 2 versus 3; p = 0.023 and p = 0.036, respectively) and required significantly more procedures (median 2 versus 1; p = 0.043 and p = 0.044, respectively) compared with lesions with one component.Conclusion: Sclerotherapy for (V)LMs in children is safe and effective. Bleomycin is the most frequently used agent in this clinic and seemed most effective for pure LMs. Mixed macrocystic and microcystic lesions are most difficult to treat effectively. What is Known: • A variety of agents can be used for sclerotherapy of lymphatic malformations in children. • Macrocystic lesions have favorable outcomes compared with microcystic and mixed lesions. What is New: • Bleomycin and a combination of agents seem to be most effective to treat lymphatic malformations in children. • Mixed macrocystic and microcystic lesions are more difficult to treat effectively compared with lesions with either one of these components.

BackgroundThe aim of the present study was to evaluate the efficacy and safety of 3% polidocanol foam for treating 2nd-degree haemorrhoids.MethodsA multicentre, open-label, single-arm, phase 2 trial involving 10 tertiary referral centres for haemorrhodal disease (HD) was performed. Between January and June 2019, patients with 2nd-degree haemorrhoids were prospectively included in this study. The primary outcome was to establish the success rate after one sclerotherapy session in terms of complete resolution of bleeding episodes one week after the injection. The Hemorrhoidal Disease Symptom Score (HDSS), the Short Health Scale for HD (SHS-HD) score and the Vaizey incontinence score were used to assess symptoms and their impact on quality of life and continence. Pain after the procedure, subjective symptoms and the amount and type of painkillers used were recorded. Patients were followed up for 1 year.ResultsThere were 183 patients [111 males; 60.7%, mean age 51.3 ± 13.5 (18-75) years]. Complete resolution of bleeding was reached in 125/183 patients (68.3%) at 1 week and the recurrence rate was 12% (15/125). Thirteen patients (7.4%) underwent a second sclerotherapy session, while only 1 patient (1.8%) had to undergo a third session. The overall 1-year success rate was 95.6% (175/183). The HDSS and the SHS score significantly improved from a median preoperative value of 11 and 18 to 0 and 0, respectively (p ConclusionsSclerotherapy with 3% polidocanol foam is a safe, effective, painless, repeatable and low-cost procedure in patients with bleeding haemorrhoids.

PurposeThere is paucity of data on patient-perceived outcomes of bleomycin sclerotherapy for low-flow vascular malformations. In this study, the long-term outcomes of bleomycin sclerotherapy were investigated in terms of quality of life (QoL) and patient-perceived changes in health.Materials and methodsA cohort of Dutch patients with vascular malformations treated with bleomycin sclerotherapy (June 2010-November 2015) completed a questionnaire evaluating disease symptoms, QoL (Short Form 36), patient-perceived change in health status (Global Rating of Change scales) and treatment satisfaction. QoL was assessed for the patient's status before and after treatment and was analyzed relative to an age and sex-matched Dutch reference population. Predictive factors associated with QoL and patient-perceived improvement in overall health status were assessed using multivariable linear and logistic regression analyses, respectively.ResultsSeventy-seven patients, with a median follow-up of 22 months, were enrolled. About half of the respondents (49.3%) indicated that they perceived (any form of) improvement in their overall health status. Most often improved were the specific health aspects 'pain' (54.5%) and 'overall severity of symptoms' (57.1%). No factors were significantly predictive for patient-perceived improvement in health with respect to the vascular malformation. Impairment in work- or study-related activities prior to sclerotherapy was found to negatively impact physical QoL at follow-up (p = 0.03).ConclusionApproximately half of patients with low-flow vascular malformations indicate an improvement in overall health status following bleomycin sclerotherapy, particularly concerning pain and severity of symptoms. However, most patients only perceived little to moderate improvement to their health and desire further treatment.

BackgroundThis prospective study evaluates the effectiveness and safety of Bleomycin electrosclerotherapy (BEST) for treating slow-flow vascular malformations in a pediatric cohort. While retrospective studies have reported its efficacy, prospective data in pediatric populations are limited.Methods30 pediatric patients (mean age: 9.5 years) with venous, veno-lymphatic, or capillary-veno-lymphatic malformations were enrolled in the study between 2020 and 2021 and received at least one BEST treatment. Follow-up continued through 2024 (mean: 25 months). MRI volumetry and clinical evaluation were performed at each follow-up.ResultsA total of 58 sessions (mean: 1.81 per patient) led to a median lesion volume reduction from 232 cm³ (range: 1.69 cm³-9814.12 cm³) pre-treatment to 41 cm³ (range: 0.57 cm3-1789.63 cm3) after the final session, corresponding to mean relative volume reduction of 59.4%. Symptoms resolved in 2 patients, improved in 18, and remained unchanged in 4. Minor side effects included skin hyperpigmentation (n = 6), inflammation (n = 3), temporary motion restriction (n = 1), and lymphorrhea (n = 1). No serious complications were observed.ConclusionBEST is a safe, effective treatment for pediatric slow-flow malformations, achieving lesion reduction and symptom relief. Future studies are warranted to optimize treatment protocols and establish long-term benefits.Impact statementBleomycin Electrosclerotherapy (BEST) is a safe and effective treatment for slow-flow vascular malformations in pediatric patients, achieving lesion volume reduction and symptom improvement. The study assesses BEST exclusively in a pediatric cohort using standardized MRI-based volumetry alongside clinical outcomes. BEST can be effective not only in refractory cases but also as a first-line or early-line treatment option, broadening its potential indications. By indicating a cumulative therapeutic benefit of repeated BEST sessions, the study encourages further investigations into tailored, session-based treatment strategies for large or progressive malformations.
