The Unmet Need for Clinical Guidelines on the Management of Patients with Plaque Psoriasis in Africa and the Middle East.

Purpose: Dermatologists practicing in African and Middle Eastern countries face numerous challenges when managing patients with plaque psoriasis, especially those with disease in a difficult-to-treat anatomic area or those who are a pediatric, geriatric, or pregnant patient. The publication of comprehensive, up-to-date, region-specific clinical guidelines may help to address some of these challenges and improve outcomes. We conducted a literature review to identify recent guidelines and other publications describing patients with plaque psoriasis in Africa and the Middle East.

Patients And Methods: An online literature search of the PubMed database was conducted to identify publications reporting clinical guidelines and research studies on plaque psoriasis. The search included all articles published from January 2008 to March 2020 inclusive. The titles and abstracts of all search results were screened by a reader to identify those that described patients in Africa or the Middle East.

Results: A total of 145 publications were identified by the literature search and screened by a reader. There were 10 publications that described patients in Africa or the Middle East: 4 research articles, 3 reviews, 2 guidelines, and 1 case study. The 2010 guidelines from South Africa made recommendations for treating plaque psoriasis of varying severity, although without specific recommendations for difficult-to-treat anatomic areas or pediatric, geriatric, or pregnant patients. The 2014 guideline on biologics from Saudi Arabia included recommendations for the use of these agents in patients with plaque psoriasis, including difficult-to-treat anatomic areas and pediatric patients (TNF inhibitors only), but provided no recommendations for pregnant or geriatric patients.

Conclusion: There is an urgent unmet need for comprehensive clinical guidelines on the management of patients with plaque psoriasis in Africa and the Middle East. Region-specific studies on the epidemiology, burden of disease, and the safety and effectiveness of newer pharmacotherapies are needed to support the development of such guidelines.

The Use of Post-transplantation Cyclophosphamide in Peripheral Blood HLA-matched Stem Cell Transplantation as Graft-versus-host Disease Prophylaxis in Patients With Malignant or Non-malignant Hematologic Disorders: A Single-center Experience of 52 Patients.

Clin Lymphoma Myeloma Leuk 2020 10 7;20(10):677-684. Epub 2020 May 7.

Introduction: Studies addressing the utilization of post-transplant cyclophosphamide (CY) as graft-versus-host disease (GVHD) prophylaxis in allogeneic hemopoietic stem cell transplantation from matched sibling donors are limited and with controversial results. Chronic GVHD incidence necessitating systemic treatment is around 35% in peripheral blood stem cell transplantation (PBSCT) from human leukocyte antigen-matched sibling donors.

Patients And Methods: In this study, high-dose CY was added to PBSCT aiming to reduce the incidence of GVHD to reach a lower figure compared with standard GVHD prophylaxis. Fifty-two patients with either benign or malignant hematologic disorders who underwent stem cell transplantation at Nasser Institute Hospital in Egypt from November 2017 to October 2018 were enrolled in this study. Fifty patients had fully human leukocyte antigen-matched siblings, whereas the remaining 2 patients had 1 locus class I mismatched donors. Pre-transplant conditioning regimen was fludarabine and busulfan (FLU/BU) in malignant cases (73.1%) and FLU/CY in benign hematologic disorders (26.9%) and 1 patient with hypocellular myelodysplastic syndrome. For GVHD prophylaxis, CY was given at a dose of 50 mg/kg/day on days 3 and 4 post-transplantation, and cyclosporine (CSA) starting day 5 in 96.1% of patients. For the 1-locus mismatched patients, both CSA and mycophenolate mofetil were administered starting day 5.

Results: The 1-year incidence of acute GVHD (aGVHD) was 15.3% and for chronic GVHD (cGVHD) was 13.4%. Historical data of GVHD prophylaxis at our center using CSA and methotrexate showed an incidence of 37% for aGVHD and 33.9% for cGVHD.

Conclusions: Post-transplant CY GVHD prophylaxis led to significantly less aGVHD (P = .03) and cGVHD (P = .04).
