betamethasone
Regulatory sources consulted
Approved indications
- Inflammatory manifestations of dry hyperkeratotic corticosteroid-responsive dermatoses, such as psoriasis and lichen planus.
Contraindications
Absolute

- Cutaneous tuberculosis or syphilis, viral infection, untreated fungal infection, rosacea, acne, skin atrophy, perioral dermatitis, vaccination reaction, ocular use, wounds, or diabetes.
Clinical warnings
- Major warning · Salicylic acid increases corticosteroid absorption. Avoid prolonged use, large areas, the face, skin folds, and occlusion because of adrenal suppression and systemic toxicity risk; children are more susceptible. — CIMA/AEMPS, ficha técnica 57463

- Major warning · Topical corticosteroids may cause cataracts, glaucoma, or central serous chorioretinopathy. Seek ophthalmologic assessment for blurred vision or any other visual disturbance. — CIMA/AEMPS, ficha técnica 57463

This "Year in Review" presents a curated selection of research themes and individual studies within the clinical osteoarthritis (OA) field, focusing on epidemiology and therapy. The search was conducted in electronic database MEDLINE from March 4, 2023, to March 31, 2024, specifically targeting English-language articles involving human participants. Inclusions were based on perceived importance and relevance to identifying risk factors or advancing OA treatments. A total of 6539 studies were screened by the 5 authors, resulting in 157 studies considered for potential inclusion. Ultimately, 44 studies were selected, uncovering six key OA-related themes: i) the burden of OA (mostly from Global Burden of Disease studies), ii) pain drivers and trajectories, iii) impacts of sex/gender, iv) OA risk factors, and treatments for v) hand and vi) knee OA. The prevalence of OA continues to rise, particularly affecting women, with unclear distinctions in risk factors and treatment responses between sexes. Associations with atopy were demonstrated in two significant databases. Notably, the authors were particularly interested in recent high-quality methodology randomized controlled trials focusing on hand (methotrexate, denosumab, colchicine, topical betamethasone) and knee OA with conflicting results about stem cell injection. These findings collectively contribute to show the growing burden of OA, but also to help the understanding of OA pathophysiology and inform ongoing efforts to enhance management for people with OA.
Scalp involvement is seen in a majority of individuals with psoriasis, a chronic autoimmune skin disease with variable phenotypes. Occasionally, isolated scalp involvement is observed; and this causes significant psychosocial morbidity. Management of scalp psoriasis is difficult, in part due to the difficulty of applying topical agents and its refractory nature. Various treatment options are available with variable efficacy. Topical agents include topical steroids, keratolytics, tar and anthralin compounds, vitamin D analogues, and vitamin A derivatives. The combination treatment of topical betamethasone and calcipotriene is the most effective topical therapy. Systemic agents include conventional agents such as methotrexate, cyclosporine, and oral retinoids. Biologics offer a greater efficacy, with near complete or complete clearance of the scalp. In this article we review the published literature on adult and scalp psoriasis to highlight its treatment. Articles published in peer-reviewed journals were included for qualitative analysis of the literature, including reviews, clinical trials, case series, case reports published in the electronic database (MEDLINE/PubMed) through June 2021, cross references of respective articles, and trials from clinicaltrials.gov. J Drugs Dermatol. 2022;21(8):833-837. doi:10.36849/JDD.6498.
The Antenatal Late Preterm Steroids (ALPS) trial changed clinical practice in the United States by finding that antenatal betamethasone at 34 to 36 weeks decreased short-term neonatal respiratory morbidity. However, the trial also found increased risk of neonatal hypoglycemia after betamethasone. This follow-up study focused on long-term neurodevelopmental outcomes after late preterm steroids. To evaluate whether administration of late preterm (34-36 completed weeks) corticosteroids affected childhood neurodevelopmental outcomes. Prospective follow-up study of children aged 6 years or older whose birthing parent had enrolled in the multicenter randomized clinical trial, conducted at 13 centers that participated in the Maternal-Fetal Medicine Units (MFMU) Network cycle from 2011-2016. Follow-up was from 2017-2022. Twelve milligrams of intramuscular betamethasone administered twice 24 hours apart. The primary outcome of this follow-up study was a General Conceptual Ability score less than 85 (-1 SD) on the Differential Ability Scales, 2nd Edition (DAS-II). Secondary outcomes included the Gross Motor Function Classification System level and Social Responsiveness Scale and Child Behavior Checklist scores. Multivariable analyses adjusted for prespecified variables known to be associated with the primary outcome. Sensitivity analyses used inverse probability weighting and also modeled the outcome for those lost to follow-up. Of 2831 children, 1026 enrolled and 949 (479 betamethasone, 470 placebo) completed the DAS-II at a median age of 7 years (IQR, 6.6-7.6 years). Maternal, neonatal, and childhood characteristics were similar between groups except that neonatal hypoglycemia was more common in the betamethasone group. There were no differences in the primary outcome, a general conceptual ability score less than 85, which occurred in 82 (17.1%) of the betamethasone vs 87 (18.5%) of the placebo group (adjusted relative risk, 0.94; 95% CI, 0.73-1.22). No differences in secon
Alopecia areata is an autoimmune disease leading to nonscarring hair loss on the scalp or body. There are different treatments including immunosuppressants, hair growth stimulants, and contact immunotherapy. To assess the benefits and harms of the treatments for alopecia areata (AA), alopecia totalis (AT), and alopecia universalis (AU) in children and adults. The Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, ClinicalTrials.gov and WHO ICTRP were searched up to July 2022. We included randomised controlled trials (RCTs) that evaluated classical immunosuppressants, biologics, small molecule inhibitors, contact immunotherapy, hair growth stimulants, and other therapies in paediatric and adult populations with AA. We used the standard procedures expected by Cochrane including assessment of risks of bias using RoB2 and the certainty of the evidence using GRADE. The primary outcomes were short-term hair regrowth ≥ 75% (between 12 and 26 weeks of follow-up), and incidence of serious adverse events. The secondary outcomes were long-term hair regrowth ≥ 75% (greater than 26 weeks of follow-up) and health-related quality of life. We could not perform a network meta-analysis as very few trials compared the same treatments. We presented direct comparisons and made a narrative description of the findings. We included 63 studies that tested 47 different treatments in 4817 randomised participants. All trials used a parallel-group design except one that used a cross-over design. The mean sample size was 78 participants. All trials recruited outpatients from dermatology clinics. Participants were between 2 and 74 years old. The trials included patients with AA (n = 25), AT (n = 1), AU (n = 1), mixed cases (n = 31), and unclear types of alopecia (n = 4). Thirty-three out of 63 studies (52.3%) reported the proportion of participants achieving short-term hair regrowth ≥ 75% (between 12 and 26 weeks). Forty-seven studies (74.6%) reported serious adverse events and only on
