Introduction

The persistent skin condition psoriasis is defined by scaly, silvery-white areas mainly occurring in people between 20 and 60 years old.^1,2 Approximately 1%–3% of people worldwide suffer from this inflammatory condition mediated by the immune system.^3,4 Its incidence in India ranges from 0.44 to 2.8% and mainly affects individuals in their 30 s and 40 s; the incidence rate in men is double that in females.⁵ Different subtypes of psoriasis, including guttate psoriasis,⁶ plaque psoriasis,⁷ inverse psoriasis,⁸ pustular psoriasis,^9–11 mucosal psoriasis,¹² scalp psoriasis,¹³ nail psoriasis,¹⁴ sebopsoriasis,¹⁵ mutilating psoriasis,¹⁶ erythrodermic psoriasis,¹⁷ and palmoplantar psoriasis,¹⁸ are identified depending on the parts of the body where the condition manifests.¹⁹ Psoriasis symptoms manifest as abnormal differentiation of immune cells and excessive growth of keratinocytes.²⁰ A pro-inflammatory pathway is established by the interaction between keratinocytes and several immune cells, including neutrophils, macrophages, T cells, plasmacytoid dendritic cells, and myeloid dendritic cells.²¹ These cells’ pathogenic and developmental functions are complex.^21–23 When intricate genetic and environmental elements are present, these cells collaborate to initiate the pathogenesis and progression of psoriasis.²³ People bear its psychological, financial, and bodily costs.²¹ Psoriasis has significant health effects that go beyond the skin 24. The disease can affect the whole body and may be accompanied by other medical conditions.²⁵ This is supported by the development of words such as “Systemic Psoriasis”²⁶ and “Psoriasis March”²⁷ in scientific studies. Therefore, looking at the link between psoriasis and other comorbid medical disorders is also necessary. Roughly three-quarters of people with psoriasis, especially those with severe instances, also have at least one other medical condition.²⁸ Psoriatic arthritis, metabolic syndrome, cardiovascular disease, inflammatory bowel disease, mental psychiatric disorders, malignant tumors, infections, and additional skin conditions are among the comorbidities associated with this condition.^29–41 The depiction of the data is illustrated in Figure 1, which additionally comprises the crucial considerations to be considered. Treatment plans must be modified to address the dermatological and non-dermatological comorbidities that might result from psoriasis.⁴¹

Psoriasis treatment has revolutionized in recent years, and it includes topical,^42–46 phototherapy,^47–49 traditional systemic,^50–53 biological,^54–57 and small-molecule medicines.^39,58–61 Significant advancements in understanding the autoimmune systems responsible for psoriasis have enabled the successful development of new targeted biological drugs, including antibodies that help patients by alleviating and managing symptoms by inhibiting TNF-α, IL-23, and IL-17A.^62,63 The primary objectives of psoriasis management are symptom reduction, quality of life enhancement, and disease prevention.^64–67 Conventional psoriasis therapies cause burning sensations, hyperpigmentation, and inadequate skin penetration. Research may lead to the treatment of colloidal medication delivery systems, which lower doses and systemic toxicity.^68–71 Numerous studies offer comparative instances of the characteristics of various colloidal carriers.^72–78 Nevertheless, personalized approaches and tailored remedies are imperative due to obstacles such as adverse effects, treatment resistance, safety concerns, and high costs.^19,79,80 Understanding coping tactics, psoriasis causes, and therapy efficacy is crucial to managing the condition.⁸¹ Psoriasis severity, progression, and future symptoms may be accurately predicted using mathematical models. Mathematical models may be used to discover treatments for numerous ailments.^82,83 A mathematical model of psoriasis, including immune cells, cytokines, keratinocytes, and immune-boosting medications, was created to explain its development and causes. The model predicted psoriasis behaviour and evaluated immune-boosting medications.⁸⁴

The importance of bibliometric analysis in psoriasis research cannot be overstated, as it offers a strategic platform for comprehending the evolution and current state of research in this area. The significance of bibliometric study on psoriasis is of utmost importance as it provides a comprehensive review of the research landscape, pointing out trends, knowledge gaps, and influential studies that shape the current understanding of the disease. By examining publication patterns over time, this study can identify new areas of interest, changes in research focus, and the influence of specific interventions or discoveries in the field. Researchers and clinicians can better understand the development of psoriasis research by directing future studies towards underexplored areas and ensuring that research efforts are aligned with clinical needs. Furthermore, bibliometric analysis gives insightful details about the collaboration networks, influential authors, and key institutions in psoriasis research, which can lead to greater collaboration and resource allocation.^85,86

Bibliometric analyses are now widely used in psoriasis and dermatological research. Academic articles on psoriasis have increased significantly due to study methods advancements; from 689 in 2003 to 2318 in 2023, the number of papers has increased substantially.⁸⁷ Therefore, a bibliometric analysis is crucial because it provides an exhaustive and comprehensive evaluation of the topic, points out gaps in the literature, and highlights new directions in research. It also evaluates the impact of research by highlighting essential findings, recognizing key figures, keeping an eye on emerging trends, and offering recommendations for funding choices. By reviewing significant terminologies and organizing articles chronologically, scholars may stay ahead of the curve in their field and modify their research to include recent developments. Prior bibliometric analyses of psoriasis have predominantly concentrated on particular subtypes,⁴⁰ such as nail psoriasis,⁸⁸ comorbidities,⁴⁰ psoriatic arthritis,⁸⁹ specific affected areas,⁹⁰ the relationship between psoriasis and endothelial cells⁹¹ and so forth. Table 1 represents current bibliometric studies incorporated into the literature review to strengthen the justification, increase clarity and conciseness, facilitate comparability, and enhance visual appeal.^101–103

Literature review

In the last decade, psoriasis progressed from merely investigating genetics and immunology to environmental factors and associated comorbidities, along with tailored therapy. Biologic agents acting on specific inflammatory mediators and small molecule inhibitors have transformed the treatment of moderate to severe psoriasis due to their enhanced efficacy and safety compared to traditional therapies. Earlier investigations have established that various gene products contribute significantly to the development of psoriasis. However, genes alone are not sufficient to initiate the outbreak of psoriasis as well as the reappearance of the disease in genetically vulnerable individuals, this being instigated by factors such as infections, microbiota in the skin and the gut, lipid metabolism abnormalities, sex hormone abnormalities, and mental disorders. Psoriasis can also be caused by other factors that relate to the environment, like skin injury, unhealthy habits, and drugs.¹⁰⁴ The development of psoriasis is quite polymerous and implicates immune pathogenesis, viral physics, and hyperkeratotic and angiogenic changes. It is a polygenic disease, and hence, it is controlled by both genetic and nongenetic factors. Through the wealth of information on the pathophysiology of psoriasis, it became possible to exploit several therapeutic agents, including JAK inhibitors, small molecules, and biologics with the possibility of anti-psoriatic effect. Signalling pathways used in the development of psoriasis, such as NF-κB, JAK-STAT, S1P, PDE-4, and A3AR, as well as animal models that have been used in psoriasis research, have also been discussed in this review. As with any review, the present text also emphasizes technological progress that has improved the knowledge of psoriasis.¹⁰⁵ Furthermore, advances in understanding the relationship between the gut microbiome and skin and the role of the microbiome in psoriasis have provided new insights into the pathophysiology of this disease. A study found that the formation rates of ADA for various biologics used in managing psoriasis and immunogenicity played a role in reduced bioactivity and enhanced ISR. It involves demographic factors, disease nature, other diseases, the sensitivity of detection, and other drugs that may be taken at the same time simultaneously. Hypothesis 3: Frequent treatment may not always effectively reduce ADA production, while intermittent treatment may lead to more ADA production.¹⁰⁶ The last decades of active investigations it revealed a vicious circle of pathogenic interactions between immunocytes and other cell types in the course of psoriasis. Current data suggest that dendritic cells, TH17 cells, and keratinocytes might be the main drivers of psoriasis. DCs secrete pro-inflammatory cytokines TNF-α and IL-23 that stimulate T cells to differentiate into TH17 T cells that produce important psoriatic cytokines: IL-17 and IFN-γ and IL-22. Their activity is related to skin inflammation and activation and hyperproliferation of keratinocytes. However, other cells and signaling pathways are involved in psoriasis, for example, TH9 cells, TH22 cells, CD8+ cytotoxic cells, neutrophils, γδ T cells, and cytokines and chemokines produced by them.¹⁰⁷ Furthermore, the identification of comorbidity in psoriasis as a systemic chronic disease as cardiovascular diseases and mental health disorders serves as a rationale for a more comprehensive approach to treating the skin disease, focusing not only on the symptoms and lesion but also the effects of the disease on the general well-being of the patients. The advancement of precision medicine coupled with artificial intelligence also holds great potential to boost diagnostic precision and as customize therapy per patient characteristics, thus paving a new epoch in psoriasis study and treatment.

Material and methods

The study focused on scientific literature in various sectors, including health and medicine, utilizing the Scopus database as the primary data source. The data was collected from the Scopus database from 2012 to 2023 using keywords related to “psoriasis,” such as “psoriatic disease,” “treatment,” “therapy,” “immunology,” and “biomarkers.” Bibliographic information included authors, publication titles, journals, years of publication, citation counts, and source databases. The identified articles were collected, cleaned, and verified to ensure they met the search criteria. The bibliometric analysis focused on English-language articles specifically explicitly focused on psoriasis and indexed in the Scopus database. Non-English publications, articles without abstracts, and studies unrelated to psoriasis research were excluded. This data was processed and analyzed using the database’s built-in analytic tools, allowing the survey to visualize trends in psoriasis research over time, establish connections between different concepts and research fields, identify frequently occurring keywords and themes, and explore the geographic distribution of publications. The resulting data was then analyzed to pinpoint knowledge gaps, emerging trends, and the current state of psoriasis research.

Furthermore, the study analyzes changes in scientific collaboration and output in these fields. The main objective is to discover long-term patterns in publication output while also analyzing significant trends and distributions within the academic literature through a comprehensive, data-driven examination. The findings present a valuable insight into productivity and collaboration trends over time, which have significant implications for research evaluation, literature studies, and scientific policy development. To illuminate future directions and enhance informed decision-making within the scientific and academic communities, the study suggests that ongoing monitoring of these trends is essential.

Figure 3 illustrates a systematic approach to reviewing documents related to psoriasis from the Scopus database. Initially, were 35,852 documents identified, but they were narrowed down to 27,825 based on specific search criteria. To refine the search, the process involved using the NEAR/50 operator and applying specific exclusion criteria, such as excluding articles that discuss the applications of FL and medical images and articles without abstracts. Using inclusion criteria, 23,773 documents were identified as relevant, and 20,731 were examined for further eligibility. The stage saw the exclusion of 4052 articles based on predefined criteria, while an additional 3042 were removed due to irrelevance. In the end, 18,765 documents were deemed suitable for inclusion in the study. The PRISMA diagram highlights the rigorous selection process to ensure only the most relevant studies were included.

Discussion

The study revealed significant trends between 2012 and 2023 in psoriasis. Over the years, there has been a steady increase in the number of published articles, which reached its peak between 2021 and 2023 with over 5000 articles. The increased growth results from the increased research efforts and progress in these industries. During the investigation, it was discovered that well-known journals disseminated cutting-edge discoveries in dermatology and immunology domains. Throughout the 11 years, the most active publishers were the Journal of the American Academy of Dermatology, the Journal of the European Academy of Dermatology and Venereology, and the British Journal of Dermatology. This underscores the significance of their role as the primary platforms for sharing research on immune responses, dermatological problems, and other topics. Frontiers in Immunology has increased in importance over the past few years. Feldman, Wu, Griffiths, Puig, and Reich K. were the most prolific writers in the analysis, producing over 250 articles. These numerous publications have dramatically enhanced the body of scientific knowledge. The study of publications by nation confirms that the United States leads the globe in research output, followed by China and other eminent European countries like Germany and Italy. The contribution of worldwide distribution shows the importance of immunology and dermatology on a global scale. Constant monitoring of global publication trends aids in tracking the changing terrain of international research initiatives. The bibliometric analysis provides an evidence-based perspective on the growth, primary sources, contributions, and geographic characteristics that characterize the current body of scholarly work. Keeping an eye on these metrics will always produce a data-driven understanding of the patterns and developments in these fields of study. This analysis uncovers critical patterns and distributions in the ever-changing worldwide landscape of psoriasis research during the last decade.

Conclusion

In this comprehensive analysis of psoriasis research, analysis of academic publications from 2012 to 2023 was done. The number of yearly publications has tripled over the past 10 years, indicating a strong desire to understand the complexity of psoriasis. Although the United States continues to dominate, there is a welcome diversification indicated by the rise in worldwide research. This study highlights the interdisciplinary aspects of psoriasis by revealing knowledge hubs and international interactions among authors and organisations. The knowledge gained here provides a blueprint for worldwide psoriasis initiatives, paving the way for focused financing and research goals. Continued monitoring and updated analysis to reflect the ever-changing field of immunology and dermatological developments is necessary. Illustrating research endeavours promotes global comprehension and the advancement of psoriasis treatments by highlighting opportunities for cooperative research and multidisciplinary teams. Clinicians can leverage this study for evidence-based practice and improved patient care. Periodic updates are essential to stay abreast of evolving information. In the subsequent research of psoriasis, the gaps in the genetic markers, environmental factors, and immunological studies should be cleared to optimize the concept of the targeted approach. Regarding the research gaps for future endeavors, there is a lack of follow-up data on environmental exposures, more elaborated analyses of immunological processes that affect treatment outcomes, and the amalgamation of machine learning into treatment algorithms. Psoriasis research can also be considered as an international issue that emphasizes the need for international global cooperation and data sharing. At the same time, the lack of such studies from developing countries is a crucial concern. Moreover, there is expected to be more of a focus on interprofessional collaboration to investigate the microbiome and other novel biomarkers, for example. General Utilities Weighted Quality of Life Scores and attention to the rights and wrongs of new treatment courses are needed for comprehensive and fair patient care.

The bibliometric analysis’s scope may have been masked due to the limitation of data to the Scopus database and the requirement for English publications. The study may have been limited to peer-reviewed publications by excluding other databases, which may have left out some publications in the field. The study may be biased because English publications may have excluded some seminal works in other languages. In future bibliometric research, it is suggested that multiple databases searched and those included in otherlanguages to increase the objectivity and generalization of the results.

Future perspectives

The study aimed to provide comprehensive bibliometric insights. However, the analysis was constrained by the characteristics of the underlying dataset. The inclusion of exclusively English-language publications was driven by pragmatics, but it could have resulted in the removal of potentially significant non-English contributions. Furthermore, however academically justified, reliance on the Scopus database alone raises the potential that relevant research indexed elsewhere may have escaped the current investigation. The significant patterns and distributions in the data analysis set are discovered, but the practical scope decisions still have limitations. The presence of publications in other linguistic and bibliographic domains should be widely acknowledged. The insights presented are ultimately limited by the constraints of the dataset rather than having perfect generalizability. In addition, the analysis incorporating several sources might enrich the data and enable more complex interpretations to emerge.
