Efficacy and Safety of Oral Administration of a Mixture of Probiotic Strains in Patients with Psoriasis: A Randomized Controlled Clinical Trial.

The aim of this 12-week randomized, double-blind, placebo-controlled trial was to determine the efficacy and safety of a probiotic mixture in the reduction of psoriasis severity. Ninety 18-70-year-old adults with plaque psoriasis were randomized into probiotic and placebo groups. At 12-week follow-up, 66.7% of patients in the probiotic group and 41.9% in the placebo group showed a reduction in Psoriasis Area and Severity Index of up to 75% (p < 0.05). A clinically relevant difference was observed in Physician Global Assessment index: 48.9% in the probiotic group achieved a score of 0 or 1, compared with 30.2% in the placebo group. The results of follow-up 6 months after the end of the study showed a lower risk of relapse after the intake of the probiotic mixture. Analysis of gut microbiota confirmed the efficacy of the probiotic in modulation of the microbiota composition.

Combined therapy with Endoret-Gel and plasma rich in growth factors vs Endoret-Gel alone in the management of facial rejuvenation: A comparative study.

BACKGROUND: Skin suffers progressive decrement. An endogenous regenerative technology has been developed that has the versatility to provide an autologous injectable gel (Endoret-Gel) or a liquid plasma rich in growth factors (PRGF) based on the patient´s own platelet-rich plasma. AIMS: To compare the efficacy of the combined therapy with Endoret-Gel and PRGF versus Endoret-Gel alone in the management of facial rejuvenation. METHODS: Twenty clinically diagnosed patients with aged skin received either Endoret-Gel monotherapy or Endoret-Gel + PRGF combined therapy. Patients underwent three sessions at one-month intervals and were clinically assessed for six months. Corneometry, sebumetry, and high-resolution topographic analysis were carried out. Patient self-assessment questionnaires and clinical improvement scores were also performed. RESULTS: The combined therapy showed to promote a higher hydration index. These results were also significant for spot improvement at three months, while conversely, monotherapy with Endoret-Gel demonstrated higher UV spot improvement. A significant decrease of sebum production and wrinkle development was observed for both treatment groups. Red areas also improved in a similar way at the end of the follow-up period. After Endoret-Gel or Endoret-Gel + PRGF therapy, 30% and 70% of patients referred to be very satisfied, respectively. Accordingly, 40% and 80% showed a "very improved" esthetic performance. None of the patients reported a negative change and no adverse events were recorded. CONCLUSION: Both Endoret-Gel monotherapy and the combined treatment with PRGF were shown to promote facial rejuvenation and to palliate the age-related cutaneous atrophy. The combined therapy may exert a synergistic effect that addresses both skin quality improvement and soft tissue restoration in a shorter period.

The effect of plasma rich in growth factors combined with follicular unit extraction surgery for the treatment of hair loss: A pilot study.

BACKGROUND: Hair transplant surgery using follicular unit extraction technique (FUE) is a common surgical procedure for the treatment of severe hair loss. Blood-derived autologous growth factors have also proved to promote hair regeneration in patients with different types of alopecia. AIMS: The aim of this study was to evaluate the safety and clinical efficacy of plasma rich in growth factors (PRGF) technology as an adjuvant therapy for FUE surgery in hair loss affected patients. METHODS: The biologic potential of PRGF was firstly in vitro evaluated over follicular germinal matrix and dermal papilla cells. Afterward, fifteen patients were subjected to routine FUE procedure while 15 patients underwent FUE+PRGF therapy. PRGF group included intradermal injections of growth factors and follicular transfer unit (FTU) preservation in an autologous fibrin clot. Postsurgical patient satisfaction and clinical improvement were evaluated, and PRGF or saline-preserved hair grafts were histomorphometrically analyzed. RESULTS: Follicular cell proliferation and migration was induced after autologous growth factors treatment. PRGF-preserved FTUs presented higher bioactivity signals and improved integrity of perifollicular structures and extracellular matrix proteins such as collagen and elastic fibers. PRGF not only reduced the postsurgical crust healing and hair fixation period, but also decreased the inflammatory pain and itching sensation. CONCLUSIONS: This preliminary data demonstrate that PRGF is able to minimize the postsurgical follicle loss and potentiate the performance of grafted hairs. The fibrin clot not only acts as a protective barrier against environmental factors, but also provides a biologically active scaffold that induces resident cell proliferation and maintains an optimal integrity of the grafted hair.

Effects of Curcuma extract and visible light on adults with plaque psoriasis.

INTRODUCTION: We conducted a phase IV randomized, double-blind, placebo-controlled, pilot clinical trial to investigate the safety and efficacy of oral curcumin together with local phototherapy in patients with plaque psoriasis. MATERIALS AND METHODS: Patients with moderate to severe psoriasis received Curcuma extract orally with real visible light phototherapy (VLRT) or simulated visible light phototherapy (VLST) in the experimental area, while the rest of the body surface was treated with ultraviolet A (UVA) radiation. The endpoints were the number of responders and the temporal course of the response. The secondary outcomes were related to safety and adverse events. RESULTS: Twenty-one patients were included in the study. In the intention-to-treat analysis, no patients included in the VLRT group showed "moderate" or "severe" plaques after the treatment, in contrast to the patients included in the VSLT group (p<0.01). Parallelisms in the evolution of PGA, BSA, and PASI scores were observed in the two groups following the treatment. At the end of the study period, 76% of all patients showed a response in the BSA exposed to UVA. Lesions on the experimental area showed a response in 81% of the patients in the VLRT group and 30% of the patients in the VLST group. There were no study-related adverse events that necessitated participant withdrawal. CONCLUSION: The results suggested that moderate to severe plaque psoriasis should show a therapeutic response to orally administered Curcuma if activated with visible light phototherapy, a new therapeutic method that would be safer for patients than existing treatments.
