StudyYear of publication [ref]Number of patientsAssociated conditionTreatment employedResponse

Mayer et al2008 [1]2SLE (2)(1) No treatment

(1) Did not require treatment
(2) Response after unclear duration

Wondergem et al2006 [4]1SLEPrednisone (1 mg/kg/day unknown duration), IVIGPersistent hemolysis despite prednisone, response to IVIG and subsequent tapering of steroids with resolution of hemolysis

Sudha Reddy et al2011 [5]1UnknownPrednisolone (2 mg/kg/day for 4 weeks), tapered to alternating day steroidsResponse, tapered to corticosteroids on alternating days

Tanaka et al2006 [6]1Following chicken pox infectionMethylprednisone (1000 mg/day unclear duration), prednisolone (60 mg/day for 4 weeks tapered to 10 mg/daily)Initial response to methylprednisolone, worsening thrombocytopenia following taper treated with reinitiation of methylprednisone and IVIG (400 mg/day 3 days) with stabilization, recurrent hemolysis requiring reinitiation of prednisone

Win et al2007 [7]2(1) Unknown
(2) Splenic T-cell angioimmunoblastic non-Hodgkin’s lymphoma
(1) Prednisone (40 mg/day unclear duration) and IVIG (0.4 mg/kg for 5 days)
(2) prednisone (60 mg/kg, increased to 100 mg/kg unclear duration) and IVIG (2 mg/kg for 2 days); VCP (cyclophosphamide 750 mg/m2, vincristine 2 mg and prednisone 50 mg unclear number of cycles); rituximab (325 mg/m2 for 2 weeks); splenectomy
(1) Response with stabilization in hemoglobin
(2) No response to steroids/IVIG, chemotherapy or rituximab; response to splenectomy with stabilization in hemoglobin

Morselli et al2002 [8]1UnknownPrednisone (1 mg/kg/day) with taper; over three weeks to 25 mg/daily, rituximab (325 mg/m2 for 2 weekly courses)Response to initial steroid treatment with following taper, recurrence in hemolysis with response and stabilization in hemoglobin with 2 cycles of rituximab

Qiao et al2016 [9]1Primary Sjorgen syndromeMethylprednisone (40 mg/day unknown duration) transitioned to pulse methylprednisone (1000 mg/day for 3 days) followed by prednisone 50 mg/day (unknown duration), patient received G-CSF and cyclophosphamide 0.2 mg every other day to treat concomitant agranulocytosisComplete response with resolution of hemolysis

Imataki et al2020 [10]1Idiopathic, prior autologous stem cell transplant for DLBCLPrednisolone (1 mg/kg for unknown duration)Progressive hemolysis without response

Hirano et al2016 [11]1SLEPrednisolone (2 mg/kg for 2 months and subsequent taper), 2 courses of methylprednisone pulse (unknown dosage/duration) MMF (1000 mg/day tapered 500 mg/day for unknown duration)Response with stabilization in hemoglobin

Scaramucci et al2005 [12]1IdiopathicPrednisone (1 mg/kg/day unknown duration with taper), rituximab (375 mg/m2 four weekly courses)Response with prednisone with relapse following taper, complete response to rituximab

Elharake et al2019 [13]1EBV PCR positiveMethylprednisone (unknown dosage and duration), plasma exchangeResponse with hemoglobin stability

Haller et al2009 [14]1Post liver transplant without evidence of alloantibodies, EBV and CMV positiveIV methylprednisone (1 mg/kg QID for 7 days) transitioned to prednisolone (1 mg/kg daily), rituximab (325 mg/m2 for 4 weekly courses), IVIG (0.5 g/kg, dose for 3 weekly doses), prednisolone tapered to 2.5 mg daily over 6 months and subsequently continued as GVHD prophylaxisNo response to initial methylprednisone, response to rituximab with stabilization in hemoglobin and resolution of transfusion requirements

Zhang et al2012 [15]1Hodgkin lymphomaIV methylprednisone (unclear dose and duration), 1 cycle of rituximab (unclear dose)No response to initial methylprednisone, response to rituximab with hemoglobin stabilization

Rai et al2017 [16]2IdiopathicBoth cases received corticosteroids (unknown medication, dose and duration)Both had response to corticosteroid therapy with improvement in hemolysis however long term follow up unknown

Gupta et al2011 [17]1IdiopathicIV methylprednisone (unknown dose and duration), plasmapheresis for 7 daily doses, rituximab (375 mg/m2 for four weekly doses)No response to initial corticosteroid or plasmapheresis, stabilization in hemoglobin following initiation of rituximab and transfusion independence

Webster et al2004 [18]1IdiopathicCyclophosphamide 50 mg daily and prednisone 10 mg alternating days for 1 month; rituximab 700 mg IV for 4 weekly dosesDiscontinued cyclophosphamide/prednisone due to side effects and progressive hemolysis, response to rituximab with resolution of transfusion requirements and hemoglobin stabilization

DLBCL: diffuse large b-cell lymphoma, MMF: mycophenolate mofetil VCP: vincristine, cyclophosphamide, and prednisone.
