[PMID: 39059349 DOI: 10.1016/j.biopha.2024.117181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2024] [Revised: 07/18/2024] [Accepted: 07/22/2024] [Indexed: 07/28/2024] Open
Abstract
Infantile hemangioma (IH) is the most common benign tumor in infants and usually resolves on its own. However, a small portion of IH cases are accompanied by serious complications and other problems, impacting the physical and psychological health of the children affected. The pathogenesis of IH is highly controversial. Studies have shown that abnormal blood vessel formation is an important pathological basis for the development of IH. Compared with that in normal tissues, the equilibrium of blood vessel growth at the tumor site is disrupted, and interactions among other types of cells, such as immune cells, promote the rapid proliferation and migration of vascular tissue cells and the construction of vascular networks. Currently, propranolol is the most common systemic drug used to inhibit the growth of IHs and accelerate their regression. The purpose of this review is to provide the latest research on the mechanisms of angiogenesis in IH. We discuss the possible roles of three major factors, namely, estrogen, hypoxia, and inflammation, in the development of IH. Additionally, we summarize the key roles of tumor cell subpopulations, such as pericytes, in the proliferation and regression of IH considering evidence from the past few years, with an emphasis on the possible mechanisms of propranolol in the treatment of IH. Angiogenesis is an important event during the development of IH, and an in-depth understanding of the molecular mechanisms of angiogenesis will provide new insights into the biology and clinical treatment of IH.

Abstract
Background Despite the excellent clinical efficacy of oral propranolol in the management of infantile haemangiomas (IHs), there is a need to further evaluate other beta blockers that may be equally efficacious but result in lesser adverse effects. We compared the efficacy and short-term safety of atenolol, a hydrophilic cardio-selective beta blocker, with propranolol, in the treatment of IHs. Materials and Methods Sixty patients with complicated and/or cosmetically significant IHs were randomised into two groups, oral propranolol group (2 mg/kg/day) and the oral atenolol (1 mg/kg/day) group, respectively, for 9 months. Patients were assessed clinically, by the use of Doppler ultrasonography (USG) and measurement of serum hypoxia-inducible factor 1 alpha (HIF-1α). Results Twenty-two of 30 patients achieved complete clearance in the propranolol group (0.73; 95% CI = 0.54 to 0.87) compared with 13 of 25 patients in the atenolol group (0.52; 95% CI = 0.31 to 0.72). The mean time to achieve Physician Global Assessment Score 5 (PGA5) (25.00 ± 8.87 weeks) was significantly lesser in the propranolol group versus the atenolol group (31.69 ± 7.01 weeks; log-rank = 0.04). The two groups were comparable in terms of adverse effect profile, degree of volume reduction in USG and reduction in HIF-1α levels. Conclusions Propranolol (2 mg/kg/day) is better than atenolol (1 mg/kg/day) in inducing complete clinical clearance of IH although the results need to be reproduced in larger studies.

Skin sequelae in patients with infantile hemangioma: a systematic review. Eur J Pediatr 2023; 182:479-488. [PMID: 36434402 DOI: 10.1007/s00431-022-04688-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 10/26/2022] [Accepted: 11/01/2022] [Indexed: 11/27/2022]
Abstract
Infantile hemangioma (IH) is the most common vascular tumor in infancy. Although IHs can regress spontaneously, some problematic IHs still need treatment. However, either treated or untreated IHs may leave skin sequelae which can cause permanent disfigurement. Many studies evaluated the short-term efficacy of different kinds of treatment, but now, few studies are focusing on long-term skin sequelae. The objectives of our systemic review were to identify skin sequelae of IH thoroughly, determine specific factors associated with long-term IH sequelae, and learn how to improve these sequelae. We searched the following electronic databases: PubMed, EMBASE, Cochrane Library, and Clinicaltrials.gov. Three independent authors assessed the articles, and we reported this systemic review following PRISMA guidelines. Of 4448 articles initially identified, 62 underwent full-text review, and 17 met inclusion criteria. The overall rate of sequelae ranged from 5.3 to 93.5%. Factors associated with skin sequelae included patients' demographics, hemangioma characteristics, and treatment factors. What is Known: • Infantile hemangioma is the most common vascular tumor during infancy. • Infantile hemangiomas can regress spontaneously but either treated or untreated patients may leave permanent skin sequelae. What is New: • Skin sequelae in involuted Infantile hemangiomas are very common. • It is significant to prevent, recognize, and improve skin sequelae of infantile hemangiomas.

RSC Adv 2022; 13:355-369. [PMID: 36605638 PMCID: PMC9768849 DOI: 10.1039/d2ra04836a] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 11/15/2022] [Indexed: 12/24/2022] Open
Abstract
The rapid spread of dengue virus has now emerged as a major health problem worldwide, particularly in tropical and sub-tropical regions. Nearly half of the human population is at risk of getting infection. Among the proteomes of dengue virus, nonstructural protein NS5 is conserved across the genus Flavivirus. NS5 comprises methyltransferase enzyme (MTase) domain, which helps in viral RNA capping, and RNA-dependent RNA polymerase (RdRp) domain, which is important for the virus replication. Negative modulation of NS5 decreases its activity and associated functions. Despite recent advances, there is still an immense need for effective approaches toward drug discovery against dengue virus. Drug repurposing is an approach to identify the new therapeutic indications of already approved drugs, for the treatment of both common and rare diseases, and can potentially lower the cost, and time required for drug discovery and development. In this study, we evaluated 75 compounds (grouped into 15 mixtures), including 13 natural compounds and 62 drugs, by using biophysical methods, for their ability to interact with NS5 protein, which were further validated by molecular docking and simulation studies. Our current study led to the identification of 12 ligands, including both 9 US-FDA approved drugs and 3 natural products that need to be further studied as potential antiviral agents against dengue virus.

Abstract
Infantile hemangiomas (IHs) are common vascular lesions which are benign but can cause significant functional and cosmetic morbidity. Since the fortuitous discovery of propranolol being effective to treat IH over a decade ago, the therapy and prognosis for children with IH have improved dramatically. Oral propranolol (as well as other oral beta-blockers and topical timolol) are safe and effective treatments, and have now supplanted other therapies. Making the correct diagnosis is crucial, because other vascular lesions can mimic IH. In addition, IH can be the first manifestation of an underlying syndrome. For IH requiring treatment, initiating treatment early is key to optimizing success. Therefore, early recognition and referral, if necessary, are important. Continued research on IH, both basic science and clinical, should result in continued advances.

Abstract
Infantile hemangioma (IH) is the most common benign vascular tumor of infancy, affecting about 5% of infants. It has a characteristic growth pattern of early rapid proliferation followed by progressive involution. Although most IH evolve favorably, complications are observed in 10-15% of cases, justifying treatment. For over 10 years now, propranolol has become the first-line therapy for complicated IH, revolutionizing their management and their prognosis. In this article, we review the clinical features, associations, complications/sequelae and therapeutic approaches for IH, focusing on current medical therapy. Indications for treatment and various treatment options, including propranolol and other oral β-blockers, topical timolol, and corticosteroids are presented. Current controversies regarding oral propranolol such as pre-treatment screening, in- vs out-patient initiation of treatment, early and potential long-term side effects and recommended monitoring are discussed.
