Autoimmune Myelofibrosis as a Presenting Feature of Childhood-Onset Systemic Lupus Erythematosus: A Case Report With Review of Pediatric Literature

C-Reactive Protein: Pathophysiology, Diagnosis, False Test Results and a Novel Diagnostic Algorithm for Clinicians

The current literature provides a body of evidence on C-Reactive Protein (CRP) and its potential role in inflammation. However, most pieces of evidence are sparse and controversial. This critical state-of-the-art monography provides all the crucial data on the potential biochemical properties of the protein, along with further evidence on its potential pathobiology, both for its pentameric and monomeric forms, including information for its ligands as well as the possible function of autoantibodies against the protein. Furthermore, the current evidence on its potential utility as a biomarker of various diseases is presented, of all cardiovascular, respiratory, hepatobiliary, gastrointestinal, pancreatic, renal, gynecological, andrological, dental, oral, otorhinolaryngological, ophthalmological, dermatological, musculoskeletal, neurological, mental, splenic, thyroid conditions, as well as infections, autoimmune-supposed conditions and neoplasms, including other possible factors that have been linked with elevated concentrations of that protein. Moreover, data on molecular diagnostics on CRP are discussed, and possible etiologies of false test results are highlighted. Additionally, this review evaluates all current pieces of evidence on CRP and systemic inflammation, and highlights future goals. Finally, a novel diagnostic algorithm to carefully assess the CRP level for a precise diagnosis of a medical condition is illustrated.

Pediatric autoimmune myelofibrosis: Experience from a large pediatric tertiary care center

Autoimmune myelofibrosis (AIMF) is a rare disorder characterized by cytopenias and autoimmunity, with characteristic bone marrow findings that include lymphocytic infiltration and fibrosis. AIMF is described predominantly in adult populations who have systemic lupus erythematosis (SLE), with scant pediatric cases described mainly in older adolescents with SLE. Here, we described the largest single-center pediatric experience of pediatric autoimmune myelofibrosis (PAIMF) series, demonstrating both similarities and distinctions from the adult experience. Patients overall respond well to steroid therapy, but these patients were significantly younger, infrequently carried a diagnosis of SLE, and causative genetic lesions were identified in many cases.

Autoimmune Myelofibrosis in a 12-Year-old Male With Monosomy 7, Systemic Lupus Erythematous and Lupus Nephritis: A Case Report and Review of the Literature

Complete or partial loss of chromosome 7 is a common and well-known cytogenetic abnormality associated with preleukemic myelodysplasia and myeloid leukemia but not with autoimmune myelofibrosis. Detection of this molecular change represents poor prognosis. When malignant transformation occurs, the condition tends to be chemotherapy-resistant requiring haematopoietic stem cell transplantation (HSCT) to obtain a cure. Disappearance after immunosuppressive therapy has been documented in children with hematological disorders but not in association with cyclophosphamide and systemic lupus erythematous.We present the interesting case of a 12-year-old male with monosomy 7, systemic lupus erythematous, and lupus nephritis with the resolution of the monosomy 7 and autoimmune myelofibrosis after treatment with cyclophosphamide, along with a review of the literature.
