Do impaired memory, cognitive dysfunction and distress play a role in methotrexate-related neutropenia in rheumatoid arthritis patients? A comparative study

We evaluated the roles of sociocultural status, distress and cognitive functions in rheumatoid arthritis (RA) patients who developed methotrexate (MTX)-related neutropenia. The data of 37 RA patients with MTX-related neutropenia who were being followed up at 3 centers were evaluated. The control group included 74 RA patients. The clinical features, biochemical tests and treatment modalities of the patients were obtained from hospital files. The mini-mental state examination (MMSE) test and the Hospital Anxiety and Depression Scale (HADS) were administered for all RA patients with neutropenia as well as the control group. The frequencies of male patients, illiterate patients, patients living alone, patients with serious visual impairment, those with low income, and patients with high creatinine were significantly higher among RA patients with MTX-related neutropenia than in controls ( p values
