Systematic review and meta-analysis Literature-based Clinical Retrospective Analysis of Acquired Reactive Perforating Collagenosis
Bibliographic record
Abstract
Objective: Acquired reactive perforating collagenosis (ARPC) is a rare dermatosis that usually associated with systemic disease. The associations, characteristics and treatment regimen of ARPC are not well understood. This systematic review was performed to retrospectively evaluate the diagnosis and treatment statuses of ARPC. Methods: A systematic review of the PubMed, Embase, and Scopus databases was independently performed by 2 reviewers. Data were extracted and qualitatively analyzed. The quality of the articles was assessed by using the Newcastle–Ottawa scale. The data are described in this article. The study was registered in International Prospective Register of Systematic Reviews system with CRD 42023448576. Results: In total, 189 patients (98 women, 91 men) in 124 studies were analyzed. Their mean age was 57.31 ± 15.21 years. A total of 88.89% ( n = 168) of the patients had one or more systemic diseases, of which 57.67% ( n = 109) had diabetes mellitus, 29.10% ( n = 55) had chronic renal failure, 25.93% ( n = 49) had hypertension, and 13.76% had malignancy ( n = 26). The most frequently affected area was the lower extremities (72.49%, n = 137), followed by the trunk (70.37%, n = 133) and the upper extremities (63.49%, n = 120). One hundred sixty (84.66%) patients had pruritus, and 32.80% ( n = 62) of them were positive for the Koebner phenomenon. Oral antihistamines and topical steroids were the most common treatments in this study, followed by narrow-band ultraviolet B therapy and allopurinol. Management of concomitant systemic diseases also resulted in improvement of ARPC. Conclusion: In this systematic review, ARPC was frequently associated with systemic diseases, especially diabetes mellitus, renal failure, hypertension, and malignancy. The lower extremities and trunk were the most frequently affected areas, and pruritus usually appeared. Antihistamines and topical steroids were the most commonly used treatments, and we recommend narrow-band ultraviolet B therapy as the first-line treatment. Management of systemic diseases and relief of pruritus should be considered simultaneously.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
