Background: Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, characterised by multi-organ affections. Haematological involvement is a common manifestation of SLE, consisting of autoimmune peripheral cytopenia. Autoimmune myelofibrosis (AIMF) is a rare cause of cytopenia in SLE; it could precede or be concurrent with the diagnosis of SLE. There are few studies that describe this association.
Case Description: We report a case of AIMF revealing the diagnosis of SLE in 34-year-old female, presented with episodes of gingival bleeding associated with peripheral inflammatory polyarthralgia, photosensitivity and deterioration of general condition. Clinical examination revealed a soft pitting oedema in the lower limbs. Laboratory investigations showed a pancytopenia, inflammatory biological syndrome, with positive 24-hour proteinuria and anti-native DNA antibodies. A bone marrow biopsy showed diffuse myelofibrosis associated with maturation disorders and no tumour infiltrate. Renal biopsy revealed proliferative glomerulonephritis class III with immune deposits.
Conclusion: The association of AIMF with SLE has been rarely reported, and it could be another cause for cytopenia in SLE.
Learning Points: Autoimmune myelofibrosis can be associated with systemic lupus erythematosus (SLE), even though it is rare.This association should be considered when pancytopenia is not well controlled during SLE, prompting a bone marrow biopsy to confirm the diagnosis.The therapeutic management of this association is the same as that used in SLE.

Primary myelofibrosis (PMF) is an uncommon chronic myeloproliferative disorder that is commonly associated with Janus kinase 2 (JAK-2), calreticulin (CALR), or thrombopoietin receptor (MPL) mutations. Pre-fibrotic PMF (also known as pre-PMF or early PMF) is a subtype of PMF that is defined by a lower grade of fibrosis. In this report, we present a rare case of warm autoimmune hemolytic anemia (wAIHA) associated with pre-PMF.

Autoimmune myelofibrosis (AIMF) is a distinct, underrecognized, and rare cause of bone marrow fibrosis. It carries a favorable outcome and responds well to immunosuppression. Systemic lupus erythematosus is the most common association with AIMF, but there are other cases of associated autoimmune disorders defined in the literature.

The Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway functions as a central hub for transmitting signals from more than 50 cytokines, playing a pivotal role in maintaining hematopoiesis, immune balance, and tissue homeostasis. Dysregulation of this pathway has been implicated in various diseases, including immunodeficiency, autoimmune conditions, hematological disorders, and certain cancers. Proteins within this pathway have emerged as effective therapeutic targets for managing these conditions, with various approaches developed to modulate key nodes in the signaling process, spanning from receptor engagement to transcription factor activation.
