Intra-lesional Corticosteroids Versus Platelet-Rich Plasma Versus Platelet-Rich Fibrin for the Treatment of Oral Lichen Planus: A Systematic Review and Network Meta-Analysis.

Oral lichen planus (OLP) is a potentially malignant disorder affecting the oral mucosa. Platelet concentrates, including platelet-rich plasma (PRP) and platelet-rich fibrin (PRF), have emerged as promising alternative treatments to corticosteroids. This study aims to comprehensively evaluate the effectiveness of PRP and PRF in the management of patients with OLP. We conducted a comprehensive search of PubMed, Scopus, Web of Science, and the Cochrane Library for randomized controlled trials (RCTs) involving patients with OLP comparing intralesional PRP or PRF with corticosteroids up to August 2024. The primary outcomes assessed were changes in lesion size, pain scores, and Thongprasom scores. Network meta-analysis (NMA) was used. Data were pooled using summary effect sizes with corresponding 95% confidence intervals (CIs) in a random-effects model based on the DerSimonian-Laird method. Eight studies comprising 157 patients and 250 lesions were included in the final analysis. Compared to corticosteroids, no significant differences were observed among PRF and PRP in terms of changes in lesion size, pain scores, clinical severity scores, and adverse events. NMA ranking showed that PRF was the best-ranking treatment in reducing lesion sizes (SUCRA values: 72.6%, 75.8%, 66.2%, 80.8%, and 77.5% at first, second, third, fourth, and eighth weeks of assessment), followed by corticosteroids, and PRP. Moreover, PRF was the best-ranking treatment in reducing pain score at the first, third, and eighth weeks of assessment (SUCRA values: 91.8%, 86%, and 85.9%), while PRP was the best intervention at the second and fourth weeks of assessment (SUCRA values: 61.3%, and 90.2%). Also, PRF was the best intervention in terms of Thongprasom scores at eight weeks of assessment (SUCRA value: 77.3%), while PRP was the best intervention at the fourth week of assessment with value of 78.1%. PRF and PRP showed comparable results with intralesional corticosteroids in all studied parameters. Considering treatments ranking, PRF was the best intervention. The optimal treatment modality for OLP varies on different clinical conditions.

Erythema nodosum in renal transplant recipients: multiple cases and review of literature.

We report 4 renal transplant recipients with erythema nodosum. Erythema nodosum is a cutaneous inflammatory reaction located on the anterior aspects of the lower extremities. It may be associated with a wide variety of diseases, including infections (as in Cases 1 and 2), sarcoidosis, rheumatologic diseases, inflammatory bowel diseases (as in Case 3), medications (as in Case 4), autoimmune disorders, pregnancy, and malignancies. Histopathologically, erythema nodosum is the stereotypical example of a mostly septal panniculitis with no vasculitis, and the inflammatory infiltrate in the septa varies with age of the lesion. In early lesions edema, hemorrhage, and neutrophils are responsible for the septal thickening, whereas fibrosis, peri-septal granulation tissue, lymphocytes, and multinucleated giant cells are the main findings in late stage. Etiological management - by anti-tuberculous therapy in Cases 1 and 2, by salazopyrin in Case 3, and by discontinuation of ciprofloxacin in Case 4 - was associated with regression. Erythema nodosum can develop in renal transplant patients who did not receive induction therapy, non-rejecters, and those with steroid-free protocols. Management of erythema nodosum should be directed to the underlying associated condition, which could be tuberculosis, inflammatory bowel disease, or drug related.

Active management of post-renal transplantation BK virus nephropathy: preliminary report.

OBJECTIVE: To assess the efficacy of leflunomide, intravenous immunoglobulins, and ciprofloxacin as active treatment of postrenal transplant BK virus nephropathy (BKVN) in graft outcome at 1 year. PATIENTS AND METHODS: Renal transplant recipients with positive results of 2 BK virus polymerase chain reaction tests of urine and blood underwent graft biopsy to confirm BKVN. If BKVN was diagnosed, antimetabolite therapy (mycophenolate mofetil or azathioprine) was changed to leflunomide therapy accompanied by a course of immunoglobulin and oral ciproflxacin. RESULTS: Of 18 patients evaluated, 72% were men. Nine patients received cadaveric organs, with a mean of 3.6 HLA mismatches. All patients received induction thereapy (61% thymoglobulin), and 61% received antirejection therapy before BKVN was diagnosed. Maintenance immunosuppression therapy was primarily with prednisolone (94%); mycophenolate mofetil, 2 g/d (94%); and tacrolimus (61%). At baseline, mean (SD) creatinine clearance was 35.6 (11.5) mL/min/1.73(2), which decreased to 29.3 (17.3) mL/min/1.73(2) at 1 year (P = .01). Patients were divided into 2 groups of 9 each according to creatinine clearance values. In group 1, baseline value was 44.5 (6.6) mL/min/1.73(2), compared with 25.36 (7.8) mL/min/1.73(2) in group 2, which decreased to 42.66 (12.8) mL/min/1.73(2) (P = .23) and 16.76 (9.0) mL/min/1.73(2) (P = .009), respectively, at 1 year. Three grafts (16.7%) were lost by the end of the study, all in group 2 (P = .03). CONCLUSION: Late diagnosis and intensive immunosuppression predispose to BKVN. Early active treatment of BKVN may improve graft outcome at 1 year posttransplantation.

Monascus purpureus Went rice in nephrotic hyperlipidemia.

BACKGROUND: Nephrotic dyslipidemia is a risk factor for the development of systemic atherosclerosis; and may aggravate glomerulosclerosis and enhance progression of glomerular disease. We aimed to assess the efficacy and safety of Monascus purpureus Went rice vs. fluvastatin therapy in the management of nephrotic dyslipidemia. MATERIALS AND METHODS: Seventy-two patients with persistent idiopathic nephrotic syndrome (NS) with secondary dyslipidemia were included. They were randomly allocated into three age and sex-matched groups. The first group comprised 20 cases and were given M. purpureus Went rice in a dose of 600 mg twice/day for 1 month then once daily, the second group comprised 30 cases were given fluvastatin in a daily dose of 20 mg. The remaining 22 received no antidyslipidemic therapy and constituted a control group. All of these patients were subjected to thorough laboratory investigations including renal function tests and lipogram. Moreover, the neuromuscular status was evaluated with electromyography and nerve conduction velocity. RESULTS: Our results showed that both fluvstatin and M. purpureus Went rice were well tolerated with no evidence of significant side effects including neuromuscular functions. Both of them significantly reduced cholesterol after 6 months and 1 year. CONCLUSION: Monascus purpureus Went rice is safe, effective, and economic treatment strategy for nephrotic dyslipidemia.
