Efficacy of mycophenolate mofetil treatment in patients with immune thrombocytopenia who have received at least one series of treatment: a single-center study

Öz

Background: The objective of this study was to evaluate the efficacy of mycophenolate mofetil (MMF) as a second- or third-line treatment for chronic immune thrombocytopenia (ITP). Methods: A cohort of 13 patients with chronic ITP, who had previously been treated with eltrombopag, corticosteroids, or both, without achieving an effective response, was administered mycophenolate mofetil at a daily dosage of 1000 mg. Platelet counts were monitored at the fourth and twelfth weeks of treatment. Results: In our study, 13 patients were included, consisting of 4 females (30.8%) and 9 males (69.2%). At the 12-week mark following the initiation of MMF therapy, three out of 13 patients achieved a complete response, three out of 13 patients achieved a partial response, and seven patients showed no response. (Fig.1). At the time of transitioning to Mycophenolate Mofetil (MMF), all patients had a platelet count below 30 × 10^9/L. Approximately 40% of patients experienced an increase in platelet counts to levels above 30 × 10^9/L. Conclusions: Mycophenolate mofetil may be considered a potential treatment option for patients with chronic ITP who are refractory to first- and second-line therapies.

En az bir seri tedavi almış immun trombositopeni tanılı hastalarda mikofenolat mofetil tedavisinin etkinliği: tek merkez çalışması

Öz

Amaç: Bu çalışmanın amacı, kronik immün trombositopeni (İTP) tedavisinde ikinci veya üçüncü basamak tedavi olarak mikofenolat mofetilin (MMF) etkinliğini değerlendirmektir. Yöntemler: Daha önce eltrombopag, kortikosteroidler veya her ikisiyle tedavi edilmiş ve etkili bir yanıt alınamamış kronik İTP'li 13 hastadan oluşan bir kohorta, günlük 1000 mg mikofenolat mofetil uygulandı. Trombosit sayıları, tedavinin dördüncü ve on ikinci haftalarında izlendi. Bulgular: Çalışmamıza 4 kadın (%30,8) ve 9 erkek (%69,2) olmak üzere toplam 13 hasta dahil edildi. MMF tedavisinin başlamasından sonraki 12. haftada, 13 hastanın 3'ünde tam yanıt, 13 hastanın 3'ünde yanıt ve 7 hastada yanıt alınamamıştır. Mikofenolat Mofetil'e (MMF) geçiş sırasında tüm hastaların trombosit sayısı 30 × 10^9/L'nin altındaydı. Hastaların yaklaşık %40'ında trombosit sayılarında 30 × 10^9/L'nin üzerine çıkan bir artış görüldü. Sonuç: Mikofenolat mofetil, birinci ve ikinci basamak tedavilere dirençli kronik İTP'li hastalar için potansiyel bir tedavi seçeneği olarak düşünülebilir.
