Cytogenetic and cytokine profile in elderly patients with cytopenia.

In the elderly with cytopenia, the diagnosis of myelodysplastic syndrome (MDS) may be missed. Cytokine levels contribute to the pathology of MDS. Hence, the objectives were to evaluate cytogenetic profile as a prognostic indicator in risk stratification and cytokine levels as a screening tool in patients with cytopenia for diagnosis. Over 2 years (2016-2018), 150 elderly patients were screened. MDS diagnosis was confirmed by morphology. Interleukin-2 (IL-2) and IL-6 levels were assessed in 50 patients, and karyotyping was performed in 20 confirmed cases of MDS. Age-matched healthy controls were used for comparison of cytokine levels. Among 150 patients, 88.6% had anemia, including nutritional anemia (51.2%). MDS diagnosis was confirmed in 35 patients. In 15 patients, unexplained cytopenia (UC) was present. Karyotyping in 20 MDS patients was normal in 15 (75%) patients and revealed a complex karyotype in four (20%) patients and double chromosomal abnormality in one (5%) patient. The Revised International Prognostic Scoring System (IPSS-R) scored 91% in the low-risk group and 9% (n = 3) in the high-risk group; the latter three developed acute myeloid leukemia (AML) and two of them had a 7q deletion. Among the 15 cases of UC, one patient died from refractory anemia. No significant difference in levels of IL-2 and IL-6 were found between MDS and UC patients when compared with healthy controls, as well as between different risk groups and karyotypes. A significant difference in IL-2 levels was found in MDS patients with disease progression and with stable disease. On the basis of the findings, it is suggested that IL-2 levels will help in predicting disease progression.
