The morbidity and mortality in this syndrome are considerable, since severe SOS is associated with a mortality of more than 90% in the first hundred days of HSCT.\n\nSome risk factors are modifiable, especially those related to transplantation, but when non-alterable factors are present, preventive measures are needed that can reduce the incidence and / or severity of SOS.', 'detailedDescription': 'This is a single-center, randomized, placebo-controlled study to evaluate the efficacy and safety of N-acetylcysteine as prophylaxis of sinusoidal obstruction syndrome in patients undergoing hematopoietic stem cell transplantation Up to date, no approved medications are available for prophylactic treatment of sinusoidal obstruction syndrome in patients undergoing hematopoietic stem cell transplantation. N-acetylcysteine is a drug that has been long used as a mucolytic.
