Silent saboteur: parvovirus B19 (B19V) and its impact on refractory post-transplant anemia

Parvovirus B19 is an important yet treatable cause of refractory anemia in KTRs. Early diagnosis by PCR and tailored management incorporating reduction in immunosuppression and IVIg can result in favorable outcomes. Routine surveillance is not warranted, but targeted testing should be considered in refractory anemia cases, particularly in resource-limited settings. Further studies are needed to optimize therapeutic strategies and validate novel treatments such as Desidustat.
