Acute promyelocytic leukemia, centre, experience, Turkey.

Acute promyelocytic leukemia (APL) is a specific type of acute myeloid leukemia (AML) and has distinct hematopathologic, cytogenetic, clinical and molecular features. This study was a retrospective review of 18 adult patients (10 male, 8 female; mean age of 32.17 ± 5.66 (15-61 years) with APL at our department from January 2006 to December 2011. Following induction therapy, 17 patients achieved CR, 1 of 18 patients died of result bleeding within thirty-sixth hours of admission. In two of 18 patients developed RAS. The relapse rate was 27% (5/18). Fourteen of 18 patients (77%) have been followed in remission. APL is a malignancy requiring quick diagnosis, efficient treatment and supportive care system. ATO, one of the important therapy option in the treatment of APL, cannot be obtained easily in developing countries. This may lead to an increase in the mortality rates. The studies should be made with more number of patients and a longer period of time for accurate results.

Platelet-to-lymphocyte ratio better predicts inflammation than neutrophil-to-lymphocyte ratio in end-stage renal disease patients.

Neutrophil-to-lymphocyte ratio (NLR) was introduced as a potential marker to determine inflammation in end-stage renal disease (ESRD) patients. Recently, platelet-to-lymphocyte ratio (PLR) and NLR were found to positively correlated with inflammatory markers including tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 in cardiac and noncardiac patients. Data regarding PLR and its association with inflammation are lacking in hemodialysis (HD) and peritoneal dialysis (PD) patients. Hence, we aimed to determine the relationship between PLR, NLR, and inflammation in ESRD patients. This was a cross-sectional study involving 62 ESRD patients (29 females, 33 males; mean age, 49.6 ± 14.6 years) receiving PD or HD for ≥6 months in the Dialysis Unit of Necmettin Erbakan University. PLR, NLR, C-reactive protein, TNF-α, IL-6 levels were measured. PLR, NLR, serum high sensitive C-reactive protein, IL-6, and TNF-α levels were significantly higher in PD patients when compared with HD patients. ESRD patients with PLR ≥ 140 had significantly higher NLR, IL-6, and TNF-α levels when compared to patients with PLR < 139. In the bivariate correlation analysis, PLR was positively correlated with NLR, IL-6, and TNF-α in this population. When we compared the association of PLR and NLR with IL-6 (r = 0.371, P = 0.003 vs. r = 0.263, P = 0.04, respectively) and TNF-α (r = 0.334, P = 0.008 vs. r = 0.273, P = 0.032, respectively), PLR was found to be superior to NLR in terms of inflammation in ESRD patients. Simple calculation of PLR can predict inflammation better than NLR in ESRD patients.
