Fever during neutropenia may be a symptom of severe life threatening infection, which must be treated immediately with antibiotics. If signs of infection persist, therapy must be modified. Diagnostic measures should not delay treatment. If the risk of febrile neutropenia after chemotherapy is ≥ 20%, then prophylactic therapy with G-CSF is standard of care. After protocols with a risk of febrile neutropenia of 10-20%, G-CSF is necessary, in patients older than 65 years or with severe comorbidity, open wounds, reduced general condition. Anemia in cancer patients must be diagnosed carefully, even preoperatively. Transfusions of red blood cells are indicated in Hb levels below 7-8 g/dl. Erythropoiesis stimulating agents (ESA) are recommended after chemotherapy only when hemoglobin levels are below 11 g/dl. The Hb-level must not be increased above 12 g/dl. Anemia with functional iron deficiency (transferrin saturation < 20%) should be treated with intravenous iron, as oral iron is ineffective being not absorbed. Therapy of pain must follow diagnostic and treatment standards. Nausea or emesis following chemotherapy can be classified as minimal, low, moderate and high. The antiemetic prophylaxis should be escalated accordingly. In chemotherapy with low emetogenic potential steroids are sufficient, in the moderate level 5-HT3 receptor antagonists (setrons) are added, and in the highest level Aprepitant as third drug.

Quantitative adjuvant zinc therapy using polaprezinc was performed to examine the correlation between zinc concentration and anemia in maintenance hemodialysis patients to propose appropriate treatment. Anemia and serum zinc concentration were measured in 117 patients with chronic renal failure receiving outpatient maintenance hemodialysis at Tsuyama Chuo Kinen Hospital. Two bags of polaprezinc (containing zinc 34 mg/day) were administered to 58 patients with lower than normal zinc levels (Zn < 80 mg/dl) as adjuvant zinc therapy to assess anemia improvement. Zinc concentration and all anemia parameters showed significant positive correlation, indicating that anemia improves in patients with high serum zinc levels. Regarding the effects of adjuvant zinc therapy for improving anemia, hemoglobin levels were found to increase significantly to the highest value at 3 weeks. During treatment, the dosage of erythropoietin was reduced significantly from baseline at all assessment points. No zinc poisoning from therapy was seen, but two patients had diarrhea (1.9%). Zinc-treated patients required iron therapy due to the development of iron deficiency. Most maintenance hemodialysis patients suffer from zinc deficiency anemia, and zinc-based polaprezinc has been confirmed to be an effective and safe adjuvant zinc treatment. Most patients diagnosed as refractory anemia with no response to erythropoietin also suffer from zinc deficiency anemia, many of whom are expected to benefit from zinc therapy to improve their anemia. Possible zinc deficiency anemia should be considered in the treatment of refractory anemia with no response to erythropoietin.

This phase 3, randomized, double-blind, placebo-controlled study was designed to evaluate the efficacy and safety of darbepoetin alfa in anaemic patients with lymphoproliferative malignancies. Patients (n = 344) with lymphoma or myeloma received darbepoetin alfa 2.25 microg/kg or placebo s.c., once weekly for 12 weeks. The percentage of patients achieving a haemoglobin response was significantly higher in the darbepoetin alfa group (60%) than in the placebo group (18%) (P < 0.001), regardless of baseline endogenous erythropoietin level. However, increased responsiveness was observed in patients with lower baseline erythropoietin levels. Darbepoetin alfa also resulted in higher mean changes in haemoglobin than placebo from baseline to the last value during the treatment phase (1.80 g/dl vs 0.19 g/dl) and after 12 weeks of treatment (2.66 g/dl vs 0.69 g/dl). A significantly lower percentage of patients in the darbepoetin alfa group received red blood cell transfusions than in the placebo group (P < 0.001). The efficacy of darbepoetin alfa was consistent for patients with lymphoma or myeloma. Improvements in quality of life were also observed with darbepoetin alfa. The overall safety profile of darbepoetin alfa was consistent with that expected for this patient population. Darbepoetin alfa significantly increased haemoglobin and reduced red blood cell transfusions in patients with lymphoproliferative malignancies receiving chemotherapy.

A 5-y-old female ferret (Mustela putorius furo) was evaluated for diarrhea, anorexia, and lethargy for 1 wk. Only mild dehydration was detected on physical examination. CBC analysis revealed marked erythrocytosis with an unremarkable plasma biochemistry panel; follow-up CBC analyses revealed a consistent primary erythrocytosis. Whole-body radiographs and abdominal ultrasonography were unremarkable except for a small nephrolith in the right kidney and a small cyst in the left kidney. The plasma erythropoietin level was 17.0 mIU/mL and considered normal. In light of the diagnostic work-up and consistent erythrocytosis, a diagnosis of polycythemia vera (primary erythrocytosis) was made. The initial presentation of diarrhea resolved after treatment with oral metronidazole (20 mg/kg PO BID for 7 d). Treatment for the polycythemia consisted of a phlebotomy initially followed by chemotherapy with hydroxyurea (10 mg/kg PO BID). During the subsequent 12 mo, the hydroxyurea dose adjusted according to follow-up CBC results, and finding an optimal dosage regimen proved to be challenging. One year after the initial diagnosis, the ferret presented to an emergency clinic for acute and severe hemorrhagic diarrhea and died shortly thereafter. The postmortem diagnosis was acute venous infarction of the small and large intestine. To our knowledge, this report is the first to describe the diagnosis and long-term management of polycythemia vera in a ferret and the use of hydroxyurea for this purpose.
