Re: Hematology opinion for chronic pancytopenia in a 36-year-old female
Dear Sir/Madam,
Kindly evaluate this 36-year-old woman, a known case of systemic lupus erythematosus (mucocutaneous, musculoskeletal, and hematological involvement) with secondary antiphospholipid syndrome, for chronic pancytopenia and further management.
Relevant comorbidities
- Secondary APS with previous SVC thrombosis and collateral formation
- HFpEF with moderate pulmonary arterial hypertension
- Ulcerative colitis, biopsy proven in November 2023, currently quiescent
- Type 2 diabetes mellitus, hypothyroidism, hypertension
- Antral predominant gastritis
Current clinical status
Currently has possible URTI with fluid retention.
- Temperature: afebrile
- Pulse: 98/min
- BP: 108/68 mmHg
- RR: 26/min
- SpO₂: 90% on room air, improving to 94% on 2 L/min nasal oxygen
Respiratory examination: mildly reduced air entry in right lower zone with right-sided crepitations.
Sputum culture: Escherichia coli.
Hematology findings
CBC:
- Hb: 5.6 g/dL
- WBC: 1.56 × 10³/µL
- Platelets: 124 × 10³/µL
- Hct: 18.4%
- MCV: 89.7 fL
- RDW: 17%
- Reticulocyte count: 1.6%
Previous CBCs:
- 17/10/2026: Hb 6.0 g/dL / WBC 1.48 × 10³/µL / platelets 122 × 10³/µL
- 19/10/2026: Hb 6.5 g/dL / WBC 1.68 × 10³/µL / platelets 98 × 10³/µL
Peripheral smear: Normocytic normochromic RBCs with anisopoikilocytosis, few microcytes, occasional macrocytes and tear-drop cells. WBCs and platelets reduced on smear; few large platelets noted. Malarial parasite not seen.
Iron profile:
- Serum iron: 23 µg/dL
- TIBC: 134 µg/dL
- Ferritin: 521.95 ng/mL
LDH 189 U/L, bilirubin normal, and no biochemical evidence provided for active hemolysis.
Bone marrow biopsy, 09/09/2025
- Hypocellular marrow for age
- Trilineage hematopoiesis
- Relative erythroid reduction with dyserythropoiesis
- Focal dysmyelopoiesis with abnormal localization of immature precursors
- Increased megakaryopoiesis with focal dysmegakaryopoiesis
- Reticulin grade 1
- Impression: possibility of secondary dysplasia due to autoimmune disorder, in view of known SLE
Other relevant investigations
- USG abdomen: normal-sized spleen; no splenomegaly. Mild ascites.
- Creatinine: 1.44 mg/dL
- Urea: 57 mg/dL
- Albumin: 2.58 g/dL
- PT/INR: 15 sec / 1.01
- LFT largely within normal limits except ALP 191 U/L.
- NT-proBNP: 1663.8
- 2D echo: EF 60%, moderate PAH.
Immunosuppressive treatment history
- Rituximab 500 mg on 03/10/2025 and 28/10/2025
- Rituximab 1 g on 20/04/2026
- IV methylprednisolone 500 mg for 3 days on 20/07/2026
- IV cyclophosphamide 500 mg on 24/07/2026
- MMF stopped after initiation of cyclophosphamide
- Cyclophosphamide 500 mg IV in 500 mL NS over 3 hours is currently planned/ongoing
Current medications
- Prednisolone (Omnacortil) 30 mg OD, tapering
- Hydroxychloroquine 200 mg OD
- Apixaban 5 mg BD
- Thyroxine 125 mcg OD
- Endobloc 5 mg OD
- Mesacol 1.2 g, 1-0-1
- Benizep, 1-0-1
- Nexpro IT, 1-0-1
Request
Kindly advise regarding:
- Etiology and further work-up of chronic pancytopenia in this patient with SLE and prior marrow dysplasia.
- Need for repeat bone marrow examination, cytogenetics, flow cytometry, or other investigations as indicated.
- Supportive management, including transfusion requirements and monitoring.
- Safety of continuing IV cyclophosphamide in view of severe anemia and leukopenia, or whether it should be withheld/modified.
- Bleeding surveillance and platelet monitoring in view of concurrent apixaban use.
Thank you.
