Combined acute interstitial pneumonitis and pancytopenia induced by low-dose methotrexate in a hemodialysis patient treated for bullous pemphigoid

Abstract: Methotrexate has been widely used for many years in the treatment of a variety of diseases. Acute pneumonitis and bone marrow suppression are very serious side effects in methotrexate treatment. A 48-year-old man with end-stage renal disease undergoing chronic hemodialysis developed combined acute pneumonitis and pancytopenia after a cumulative dose of 20 mg methotrexate for bullous pemphigoid. Continuous renal replacement therapy (CRRT) can effi ciently decrease serum methotrexate concentration. A rapid impro… Show more

“…Studies have shown the effectiveness of corticosteroids in managing BP, even in complex cases like post-transplant recipients or in patients experiencing kidney transplant rejection ( 35 , 41 ). Among 59 reported cases using corticosteroids, 14 (23.73%) patients were recalcitrant ( 23 , 25 , 37 , 44 , 46 , 48 , 50 , 52 , 62 , 67 70 ). The dosage of corticosteroids was reported in twenty-two cases who responded well.…”

“…A total of 1376 articles were identified after removal of duplicates. In the final analysis, 92 articles were included, including two in vitro experiments (174,175), four animal experiments (176 179), 84 case reports and case series (24,35,88,90,126,163,170,171,180 –255), one pharmacokinetic modeling study (256), and one observational study (160). Although several articles were designed as pharmacokinetic studies in kidney failure patients (170,190,204,225,242), many participants in these studies developed methotrexate-associated toxicity and were included in case reports.…”

“…To compare the relative efficacy of extracorporeal treatments, many publications used the percentage decrease in methotrexate concentrations (44,189,201,212,232,237,240,241). However, this metric has little value unless it is adjusted for kidney function and duration of the extracorporeal treatment because serum concentrations are expected to decrease spontaneously due to endogenous processes.…”
