It is the eighth most prevalent disease worldwide with a prevalence of 9.4%. Acne scar is one of the most persistent complications of acne, causes marked psychological stress to the patient . The process of acne scar formation can be broadly divided into two stages: increased tissue formation and loss or damage of tissue, corresponding to keloid or hypertrophic scar and atrophic scar, respectively.\n\nThe ultimate severity of acne scars is correlated with acne grade and the delay in treatment of active disease. The atrophic scars include three subtypes: icepick or V-shaped, rolling or M-shaped, and boxcar or U-shaped scars. Among atrophic scars, the ice pick type represents 60%-70%; the boxcar type represents 20%-30%; and the rolling type represents 15%-25% (Salameh and Shumaker, 2022). According to the qualitative scarring grading system, a macular acne scar type also exists, which clinically shows erythematous, hyperpigmented, or hypopigmented flat marks.\n\nautologous blood product containing high concentrations of platelets in a small volume of plasma. PRP has been utilized in the treatment of orthopedic, musculoskeletal, and maxillofacial conditions for many years, it has only recently gained popularity in dermatology. PRP contains various growth factors, including platelet-derived growth factor (PDGF), transforming growth factor (TFG), vascular endothelial growth factor (VEGF), and insulin-like growth factor (IGF). These growth factors stimulate tissue remodeling and are associated with enhanced healing through the attraction of macrophages, upregulation of collagen synthesis, and promotion of tissue regeneration. Moreover, platelet-derived growth factor (PDGF) was shown to promote wound healing, angiogenesis, and tissue remodeling.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Aged \\> 18 years old.\n* Both sexes.\n* All types of atrophic acne scars\n\nExclusion Criteria:\n\n* • Pregnant or lactating women.\n\n * Coagulation disorders or anemia.\n * Skin infections.\n * Patients with hormonal disturbance.\n * Chronic disease e.g: diabetes, renal disease….etc.\n * Refusal to participate.'}, 'identificationModule': {'nctId': 'NCT06319768', 'briefTitle': 'Efficacy of Intralesional Injection of Pentoxifylline, Platelet-Rich Plasma, and Combined Pentoxifylline With Platelet-Rich Plasma in Patients With Atrophic Acne Scars', 'organization': {'class': 'OTHER', 'fullName': 'Sohag University'}, 'officialTitle': 'Efficacy of Intralesional Injection of Pentoxifylline, Platelet-Rich Plasma, and Combined', 'orgStudyIdInfo': {'id': 'soh-med-24-01-04ms'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': '- In group A (PTX group) (n:25):', 'description': 'Patients will be treated with intralesional PTX (Trentoximal Ampoule 100 mg/5 ml) in a dose of 1mg per lesion at a distance 1cm between two atrophic lesions with a maximum 20 mg per session (with insulin syringe 30Gx8mm).
