Benefits and challenges of starting a new therapeutic apheresis service in a resource-constrained setting

Therapeutic apheresis (TA) refers to a group of extracorporeal blood treatment modalities with clinical indications for which the clinicians' knowledge, availability and applicability vary widely worldwide. Therapeutic plasma exchange (TPE), the most common TA technique, is neither readily available nor affordable in many parts of Africa. This article focuses on the challenges of starting a TPE program in a resource-constrained economy and the result of a survey of Nigerian nephrology professionals on TPE. A critical appraisal of published manuscripts from Nigeria on TA was undertaken to assess uses, methods, and challenges encountered followed by a survey of the perceptions of Nigerian nephrology professionals on TPE. Survey results: 56.7% of respondents had very little or no knowledge of TPE; 40.5% moderate and only 2.7% admitting to having a good knowledge. Only 18.9% of respondents have ever participated or observed a TPE procedure with the remaining 81.1% not having any exposure to the procedure. A vast majority of the respondents 97.3% felt they needed better exposure and training in TPE and its applications. Among consultants, 56% had little knowledge, 88% had never participated or observed the TPE procedure, and 94% felt they needed better exposure and training. There is significant limitation in accessibility, availability, and use of TPE in Nigeria; knowledge of TPE and its applications is minimal among nephrology professionals. Efforts should be concentrated on improving the knowledge and availability of TPE in resource-constrained economy like Nigeria. Centers that would be able to manage cases requiring TA should be developed.
