Hemoglobin levels correlate with interleukin-6 levels in patients with advanced untreated epithelial ovarian cancer: role of inflammation in cancer-related anemia.

Anemia occurs in more than 30% of patients with epithelial ovarian cancer before any surgery. High levels of proinflammatory cytokines and increased oxidative stress may contribute to the development of cancer-related anemia. We assessed a population of previously untreated patients with advanced epithelial ovarian cancer to evaluate whether there was a correlation between hemoglobin (Hb) and parameters of inflammation and oxidative stress, stage of disease, and performance status (PS). In 91 patients with epithelial ovarian cancer and 95 healthy women matched for age, weight, and height, levels of Hb, C-reactive protein (CRP), fibrinogen (Fbg), proinflammatory cytokines, leptin, reactive oxygen species (ROS), and antioxidant enzymes were assessed at diagnosis before treatment. The correlations between Hb, parameters of inflammation and oxidative stress, stage, and PS were evaluated. Hb levels were lower in patients with advanced epithelial ovarian cancer than in control subjects and inversely related to stage and PS. Hb negatively correlated with CRP, Fbg, interleukin 1beta (IL-1beta), IL-6, tumor necrosis factor alpha (TNFalpha), and ROS, and positively correlated with leptin and glutathione peroxidase (GPx). Multivariate regression analysis showed that stage and IL-6 were independent factors determining Hb values. This evidence suggests that anemia in epithelial ovarian cancer is common and its presence is related to stage of disease and markers of inflammation.

Hemoglobin level threshold for cardiac remodeling and quality of life in myelodysplastic syndrome.

Treatment of myelodysplastic syndrome (MDS) with epoietin is costly. However, cardiac morbidity associated with anemia has not been investigated in MDS. We studied this aspect in 39 patients. Echocardiography detected cardiac remodeling in 11 of 12 transfusion-dependent versus 13 of 27 transfusion-free patients (P=0.017). Hemoglobin independently indicated cardiac hypertrophy (P=0.004); each unit increase predicted a 49% reduction in the risk of remodeling confirmed by the area under the ROC curve (0.84, P<0.0001). At Hb 10.7 g/dL, sensitivity was 96% and specificity 64%. Below this level quality of life was poorer. Our results suggest early treatment, to be confirmed by future trials.

Pentoxifylline improves hemoglobin levels in patients with erythropoietin-resistant anemia in renal failure.

It was hypothesized that pentoxifylline might improve the response to recombinant human erythropoietin (rh-Epo) in anemic renal failure patients. Sixteen patients with ESRD and rh-Epo-resistant anemia, defined by a hemoglobin of <10.7 g/dl for 6 mo before treatment and a rh-Epo dose of > or =12,000 IU/wk, were recruited. They were treated with oral pentoxifylline 400 mg o.d. for 4 mo. Ex vivo T cell generation of tumor necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma) from the patients was assessed before treatment and 6 to 8 wk after therapy. A total of 12 of 16 patients completed the study. Before therapy, the 12 patients' mean hemoglobin concentration was 9.5 +/- 0.9 g/dl. After 4 mo of pentoxifylline treatment, the mean hemoglobin concentration increased to 11.7 +/- 1.0 g/dl (P = 0.0001). Baseline ex vivo T cell expression of TNF-alpha decreased from 58% +/- 11% to 31% +/- 23% (P = 0.0007) after therapy. Likewise, IFN-gamma expression decreased from 31% +/- 10% to 13% +/- 10% (P = 0.0002). Pentoxifylline therapy may significantly improve the hemoglobin response in patients with previously rh-Epo-resistant anemia in renal failure. This may occur due to inhibition of proinflammatory cytokine production, which could interfere with the effectiveness of rh-Epo.
