RESUMO
Allogeneic HCT is curative for SCN; however, a standard conditioning regimen or intensity has not been established. We describe a patient with SCN associated with c.1A>G (M1V) mutation in ELANE gene resulting in refractoriness to G-CSF, who received reduced-intensity HCT and developed secondary graft failure requiring a second myeloablative HCT. This case suggests that M1V mutation confers a poor G-CSF response and HCT using the best available donor is beneficial.

We describe the first case, to our knowledge, of disseminated Mycobacterium bovis Bacillus Calmette-Guérin infection in a child with Bare Lymphocyte Syndrome type II after undergoing hematopoietic stem cell transplantation (HSCT). The patient presented 30 days post HSCT with fever and lymphadenitis. Lymph node, blood, and gastric aspirates were positive for M. bovis. The patient received a prolonged treatment course with a combination of isoniazid, levofloxacin, and ethambutol. Her course was further complicated by granulomatous lymphadenitis and otitis media associated with M. bovis that developed during immune suppression taper and immune reconstitution. Ultimately, the patient recovered fully, in association with restoration of immune function, and has completed 12 months of therapy.
