Cureus. 2024;16(1):e51626
Abstract
Oral lichen planus (OLP) is a chronic inflammatory condition affecting the oral mucosa. The current review investigated the potential effectiveness of injectable platelet-rich fibrin (i-PRF) as a treatment for OLP when compared to other interventions. The current review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search strategy was implemented across databases such as PubMed, Embase, Scopus, Web of Science, CINAHL, and Google Scholar. The search utilized a combination of Boolean operators (AND, OR) and Medical Subject Headings (MeSH) terms to capture relevant studies. Comparative clinical studies focusing on i-PRF as a treatment for OLP and other interventions were included. Outcomes assessed were pain, surface area of lesions, and patient satisfaction. Review Manager 5.4 was used for statistical analysis. The Risk of Bias 2.0 (RoB 2.0) tool was used to assess the methodological quality of the studies. Three studies were included for the final analysis. The findings indicated that both the i-PRF and comparison treatment groups demonstrated reductions in pain and lesion size. The post-treatment Visual Analogue Scale (VAS) scores showed a decrease in pain intensity, and there was an improvement in lesion extension in the i-PRF-treated sites. The results also revealed increased patient satisfaction with i-PRF treatment. Adverse effects were not reported or specified in the included studies. Quantitative analysis for pain (VAS) showed a mean difference of 0.38 (95% CI: 0.63-1.40), but there was no significant difference between the i-PRF and control groups at p=0.46. Though intragroup differences showed statistically significant differences between pre and post intervention, intergroup differences were not significant for any of the assessed outcomes. The findings from this study suggest that i-PRF holds promise as a potential treatment for OLP. The use of i-PRF resulted in pain reduction, lesion size improvement, and increased patient satisfaction. However, it is important to consider the limitations of the included studies, such as variability in study designs, small sample sizes, and the limited number of studies.

Abstract
Background and Objectives: Oral lichen planus (OLP) is an autoimmune, mucocutaneous, oral potentially malignant disorder (OPMD), which characteristically manifests with chronic, recalcitrant lesions, with frequent flare-ups and remissions. The precise etiopathogenesis of OLP is still debatable, although it is believed to be a T-cell-mediated disorder of an unidentified antigen. Despite the availability of various treatments, no cure for OLP exists due to its recalcitrant nature and idiopathic etiology. Platelet-rich plasma (PRP) has antioxidant, anti-inflammatory, and immunomodulatory properties, in addition to its regulatory action on keratinocyte differentiation and proliferation. These salient properties substantiate the possible role of PRP in the treatment of OLP. Our systematic review focuses on assessing the therapeutic potential of PRP as a treatment modality in OLP. Materials and Methods: We conducted a detailed literature search for studies assessing PRP as a therapeutic regimen in OLP, using the Google Scholar and PubMed/MEDLINE search engines. The search was limited to studies published from January 2000 to January 2023 and included a combination of Medical Subject Heading (MeSH) terms. ROBVIS analysis was carried out for the assessment of publication bias. Descriptive statistics were performed using Microsoft Excel. Results: This systematic review included five articles that met the inclusion criteria. Most of the included studies demonstrated that PRP treatment considerably ameliorated both objective and subjective symptoms in OLP subjects, with comparable efficacy to the standard corticosteroid treatment. Further, PRP therapy offers the added benefit of minimal adverse effects and recurrences. Conclusion: This systematic review suggests that PRP has significant therapeutic potential for treating OLP. However, further research with larger sample sizes is imperative to corroborate these findings.

American journal of hematology. 2023
Abstract
Warm antibody autoimmune hemolytic anemia (wAIHA) is characterized by hemolysis and symptomatic anemia with no approved treatment options. Fostamatinib is an oral spleen tyrosine kinase inhibitor approved in the US and Europe for treatment of adults with chronic immune thrombocytopenia. In this phase 3 study, patients with an insufficient response to ≥1 prior wAIHA treatment were randomized to fostamatinib or placebo. The primary endpoint was the proportion of patients to achieve a durable hemoglobin (Hgb) response (Hgb ≥10 g/dL and increase from baseline of ≥2 g/dL on 3 consecutive visits) during the 24-week treatment period. Ninety patients were randomized, 45 to each arm. Of the fostamatinib-treated patients, 35.6% achieved a durable Hgb response versus 26.7% on placebo (p = .398). A post hoc analysis revealed a large placebo response in Eastern European patients. Significantly more patients on fostamatinib from North America, Australia and Western Europe exhibited a durable Hgb response compared to placebo (36% vs. 10.7%, p = .030). After censoring for Hgb values impacted by steroid rescue received during screening and excluding 2 placebo patients found to likely not have wAIHA, a reanalysis demonstrated a difference in durable Hgb response between fostamatinib and placebo (15/45 [33.3%] vs. 6/43 [14.0%], p = .0395). At least 1 AE was reported in 42 (93.3%) and 40 (88.9%) patients receiving fostamatinib and placebo, respectively. The most common AEs in the fostamatinib group were diarrhea (26.7%), hypertension (24.4%), and fatigue (15.6%). In this study, fostamatinib demonstrated a clinically meaningful benefit for patients in Western regions, and no new safety signals were identified.

Zhang, Y., Mao, C., Zhu, J., Yu, W., Wang, Z., Wang, Y., Kan, Q.
BMC oral health. 2023;23(1):594
Abstract
BACKGROUND Platelet Concentrate (PC) injection therapy has shown potential as a local therapy for oral lichen planus (OLP). However, its safety and efficacy have not yet been fully established. Our research compared the efficacy of PC with topical steroid treatment in alleviating pain and symptoms related to OLP. We aims to present evidence-based alternatives that dentists can use to improve patient outcomes while reducing potential side effects. METHODS We conducted a systematic search of five electronic databases up to April 2023, including Embase, Cochrane Central Register of Controlled Trials, PubMed, OVID Medline, and WanFang, to evaluate PCs' efficacy compared to topical corticosteroid therapy for OLP. The literature quality was assessed using the Cochrane ROB tool. A fixed-effects model was used to determine the Weighted Mean Difference (WMD) and Mean Difference (MD) at a 95% confidence interval (CI) for pain severity and other relevant clinical indicators. RESULTS The comparison between topical corticosteroid therapy and PCs showed no significant difference for pain relief (WMD = -0.07, CI = 95% -0.34 to 0.19), symptom improvement (MD = -0.21, CI = 95% -0.55 to 0.13), or the severity of included lesions measured by REU scores (MD = -0.25, CI = 95% -0.32 to 0.82). CONCLUSIONS Locally injected PC have been found efficient in managing oral lichen planus, indicating that they are a promising alternative option to steroid therapy for OLP patients, particularly those who have not responded favorably to steroid therapy. However, further research is needed to establish determining the recurrence rate and long-term adverse effects. TRIAL REGISTRATION The systematic review protocol has been registered in advance with the PROSPERO database (CRD42023415372).

National journal of maxillofacial surgery. 2023;14(1):22-26
Abstract
Oral Lichen Planus (OLP), an autoimmune disorder of unclear pathogenesis affects quality of life of affected individual. Intervention regimens are multiple and still evolving due to its resistance to recover and ability to recur. Platelet rich Plasma (PRP) is a newer, promising treatment modality tested by researchers because of its low cost and negligible adverse effects. Articles were retrieved from search engines of PubMed / Medline, Scopus and Web of Science which fulfilled the eligibility criteria. Cochrane risk of bias tool assessed quality of clinical studies and Joanna Briggs Institute for case reports. A total of 4 articles were included for the systematic review, of which 2 are clinical trials and 2 case reports. All cases were of erosive nature. PRP in case reports were administered when patients did not respond to conventional therapy. PRP demonstrated effective therapeutic benefit in regards to outcome of pain and lesion appearance. PRP can be considered as a potential alternative therapy in treating non-responsive OLP. Further studies are recommended to arrive at a definitive conclusion.

Hijazi A, Ahmed W, Gaafar S
Clinical and experimental dental research. 2022
Abstract
OBJECTIVE To evaluate the clinical efficacy of intralesional platelet-rich plasma (PRP) injections compared to intralesional triamcinolone acetonide (TA) injections in the treatment of erosive oral lichen planus (EOLP). MATERIAL AND METHODS Twenty patients with EOLP were assigned randomly to either PRP or TA group. Patients received weekly intralesional injections for 4 weeks, and then followed up for 3 months on regular visits every 2 weeks. Pain scores using numerical pain score and clinical score were recorded by a blinded assessor each visit for all patients and remission score at the end of the trial was recorded. RESULTS Both groups showed significant improvement in the clinical parameters (pain and clinical score) "p = .001." Regarding remission of the lesions, 80% of patients in the PRP group showed complete remission compared to 70% in the TA group. However, there is no statistical significance when comparing the two groups in pain score, clinical score, or remission. CONCLUSIONS PRP injections could be considered as an effective alternative single treatment modality for EOLP. The protocol for this study registered in Clinicaltrials.gov registry under the identifier number: NCT03293368.

Kabbaha S, Milano A, Aldeyab MA, Thorlund K
British journal of clinical pharmacology. 2022
Abstract
AIM: Infliximab is a tumor necrosis factor-alpha inhibitor that is being used to treat children with refractory Kawasaki disease. Our purpose was to evaluate the safety and the impact of infliximab versus intravenous immunoglobulins on the incidence of coronary artery aneurysms (CAAs) and treatment resistance in children with refractory Kawasaki disease (KD). METHODS The Medline/PubMed, Embase, CINAHL, Cochrane Central Register of Controlled Trials and clinical trials registries were searched to December 2021. Randomized controlled trials (RCTs) comparing infliximab as second-line therapy to a second dose of intravenous immunoglobulin (IVIG) in children with refractory KD, reported in abstract or full text were included. Studies were selected and assessed for risk of bias by two reviewers. Data were extracted and pooled using conventional random-effects meta-analysis. The certainty of evidence was assessed using the GRADE system. RESULTS A total of 199 participants from 4 RCTs were included. Pooled risk ratio (RR) for the incidence of treatment resistance in patients treated with infliximab was RR=0.40 (95% CI 0.25-0.64). For incidence of CAAs RR was 1.20 (95% CI 0.54-2.63), the incidence of adverse effect 'infusion reactions' RR=0.48, (95% CI 0.12-1.92), and 'infections' RR=0.55 (95% CI 0.27-1.12). Overall, the GRADE strength of evidence for the primary outcomes was low. Evidence on the duration of fever and inflammatory biomarkers was sparse, heterogeneous, and inconclusive. CONCLUSION Moderate-certainty evidence indicates that infliximab may reduce the incidence of treatment resistance in children with refractory KD. However, the limited strength of evidence warrants further research.

Abstract
BACKGROUND Kawasaki disease (KD) is a major cause of coronary artery lesions (CALs) in children. Approximately 10% to 20% of children treated with intravenous immunoglobulin are intravenous immunoglobulin-resistant. This study evaluated the efficacy and safety of adding herbal medicine to conventional western medicines versus conventional western medicines alone for CALs in children with KD. METHODS This study searched 9 electronic databases until August 31, 2021. The inclusion criteria were the randomized controlled trials (RCTs) that assessed the CALs in children with KD and compared integrative treatment with conventional western treatments. Two authors searched independently for RCTs, including eligible articles that fulfilled the inclusion criteria, extracted data, and assessed the methodological quality using the Cochrane risk of bias tool. Meta-analysis was conducted using Cochrane Collaboration's Review Manager 5.4 software. The effect size was presented as the risk ratio (RR), and the fixed-effect models were used to pool the results. RESULTS The finally selected 12 studies included a total of 1030 KD patients. According to a meta-analysis, the integrative treatment showed better results than the conventional treatment in the CAL prevalence rate (RR = 2.00; 95% confidence interval [CI], 1.49-2.71; P < .00001), CAL recovery rate (RR = 1.27; 95% CI, 1.05-1.54; P = .02), and total effective rate (RR = 1.17; 95% CI, 1.11-1.23; P < .00001). Only 2 studies referred to the safety of the treatment. The asymmetrical funnel plot of the CAL prevalence rate indicated the possibility of potential publication bias. CONCLUSIONS This review found the integrative treatment to be more effective in reducing the CAL prevalence rate and increasing the CAL recovery rate and total effective rate in KD patients than conventional western treatment. However, additional well-designed RCTs will be needed further to compensate restrictions of insufficient trials on safety, methodological quality, and publication bias.

Al-Hallak N, Hamadah O, Mouhamad M, Kujan O
Oral diseases. 2022
Abstract
OBJECTIVES The use of autologous platelet concentrates has shown growing evidence as a promising therapy. We conducted a split-mouth study to evaluate the effectiveness of injectable platelet-rich fibrin (PRF) compared to triamcinolone acetonide (TA) in the treatment of oral lichen planus (OLP). MATERIALS AND METHODS This split-mouth randomized trial included twelve patients with symptomatic, bilateral OLP lesions. The participants were randomly allocated to receive a 1-mL intralesional PRF injection on one side of the buccal mucosa and a 0.5-mL TA injection on the counterpart side. The application was performed once a week for 4 weeks. The outcomes were measured using a visual analog scale score, REU score, and lesion areas. RESULTS Both injectable TA and PRF were effective in the management of oral lichen planus. After four weeks of treatment, there was an average reduction in the VAS score (68.5% i-PRF, 91% TA) and an average reduction in the REU score (74% i-PRF, 91% TA). There were no statistically significant differences between the two treatment methods (P > 0.05). CONCLUSIONS Intralesional injection with TA showed more effectiveness than i-PRF in the management of OPL lesions. Although, i-PRF cannot be considered a first-line treatment option, it showed promising alternative therapy choice with no side effects.

Acetylcholinesterase Inhibitors in Myasthenic Crisis: A Systematic Review of Observational Studies
Prado MB Jr, Adiao KJ
Neurocritical care. 2021;:1-17
Abstract
Current myasthenia gravis guidelines recommend intravenous immunoglobulin or plasmapheresis and discontinuation of pyridostigmine during myasthenic crisis. However, intravenous immunoglobulin or plasmapheresis is expensive and frequently not available in developing countries. This study aims to summarize the evidence of giving an acetylcholinesterase inhibitor in myasthenic crisis. Medline, Embase, and Cochrane databases and references were searched for observational studies that determined the use of acetylcholinesterase inhibitor in myasthenic crisis. The eligibility criteria were as follows: population, patients with myasthenic crisis, intervention (acetylcholinesterase inhibitor administration), and outcome (clinical improvement and complications). In total, 106 studies were identified, 92 through database searching (after removing duplicates) and 14 through other sources. Only eight were analyzed in the present systematic review. In five, acetylcholinesterase inhibitor was given at the start of the crisis, whereas in the other three, acetylcholinesterase inhibitor was discontinued initially and then restarted prior to extubation. Two observational analytic studies and three case reports showed improvement in different outcome measures. In the other three, improvement of outcome measures was also observed. Overall, a small proportion of patients developed cardiac arrhythmia and pneumonia after administration of acetylcholinesterase inhibitor alone, although this was not statistically different compared with those subjected to plasmapheresis. In summary, continuous intravenous infusion of pyridostigmine or neostigmine can be a substitute for intravenous immunoglobulin or plasmapheresis if these are not available during crisis; however, caution should be observed because of the aforementioned possible complications.
