Materials and Methods
A systematic review of case reports was conducted by searching PubMed,
Scopus, and Google scholar using the following keywords, (1) ’Myasthenia
Gravis’ + ’Chronic Myeloid Leukemia,’ (2) ’Myasthenia Gravis’ +
’Polycythemia Vera,’ (3) ’Myasthenia Gravis’ + ’Essential
Thrombocythemia,’ (4) ’Myasthenia Gravis’ + ’Primary/ Pre-fibrotic
Myelofibrosis’ and (5) ’Myasthenia Gravis’ + ’Myeloproliferative
neoplasms/ diseases.’ Articles other than case reports and case series
were removed. All case reports of the association of myasthenia gravis
with myeloproliferative neoplasms were identified. Cases of MPNs with
non-neurological paraneoplastic syndromes were excluded. A Comparative
study between the cases was done to identify the chronological order of
events and know whether Myasthenia gravis can be considered a possible
neurological paraneoplastic syndrome in patients with myeloproliferative
neoplasms.
