Toxic neutrophils exhibit a variety of nuclear and cytoplasmic abnormalities in Romanowsky-stained blood smears, and are associated with inflammation and infection. The purpose of the retrospective study reported here was to investigate the association of toxic neutrophils with clinicopathologic characteristics, diseases, and prognosis in cats. Cats with toxic neutrophils (n = 150) were compared with negative-control cats (n = 150). Statistical analyses included Fisher exact, independent t-, nonparametric Mann-Whitney, and chi-squared tests. Cats with toxic neutrophils had significantly (P < .05) higher prevalence of fever, icterus, vomiting, diarrhea, depression, dehydration, weakness, and cachexia, as well as leukocytosis, neutrophilia, left shift, neutropenia, anemia, hypokalemia, and hypocalcemia. The prevalence of shock, sepsis, panleukopenia, peritonitis, pneumonia, and upper respiratory tract diseases was significantly higher among these cats, as were infectious (viral and bacterial) and metabolic disorders. Control cats had a significantly higher prevalence of feline asthma, as well as allergic, idiopathic, and vascular disorders. Hospitalization duration and treatment cost were significantly (P < .001) higher in cats with toxic neutrophils. In 53 and 47% of the cats with toxic neutrophils, the leukocyte and neutrophil counts were normal, respectively, whereas in 43%, both abnormalities and left shift were absent, and toxic neutrophils were the only hematologic evidence of inflammation or infection. In conclusion, toxic neutrophils were found to be associated with certain clinicopathologic abnormalities, and when present, may aid in the diagnosis, as well as the assessment of hospitalization duration and cost. The evaluation of blood smears for toxic neutrophils provided useful clinical information.

Interleukin-12 (IL-12) enhances Th1-type T-cell responses and exerts antiangiogenic effects. We initiated a phase 1 pilot study of IL-12 in 32 patients with acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma (KS) whose KS was progressing while on antiretroviral therapy. Fifteen patients had poor prognosis T(1)S(1) disease. IL-12 was administered subcutaneously twice weekly at doses from 100 to 625 ng/kg. The maximum tolerated dose was 500 ng/kg, and the principal toxicities were flulike symptoms, transaminase or bilirubin elevations, neutropenia, hemolytic anemia, and depression. No tumor responses were seen at the lowest dose (100 ng/kg), but 17 of 24 evaluable patients at the higher doses had partial or complete responses (response rate, 71%; 95% confidence interval, 48%-89%). Only 3 of 17 patients had a change in antiretroviral therapy before responding, and there were no significant differences between responders and nonresponders with regard to changes in CD4 counts or viral loads. Patients had increases in their serum IL-12, interferon-gamma, and inducible protein-10 (IP-10) after the first dose, and increases above baseline persisted after week 4. These results provide preliminary evidence that IL-12 has substantial activity against AIDS-related KS with acceptable toxicity and warrants further investigation for this indication.

Sustained virologic response rates are significantly higher in patients who have relapsed after a previous course of therapy compared with patients who did not respond. A meta-analysis of combination therapy in patients who failed IFN monotherapy reported SVR rates of 52% in relapsers to prior therapy and 16% in nonresponders. Similarly, relapsers after combination standard IFN and RBV therapy have higher SVR rates than combination of therapy nonresponders when treated with pegylated interferon and ribavirin. For this reason, patients who relapse after a previous course of therapy should be considered potential candidates for retreatment. Factors that have been associated with SVR in these patients include genotype non-I, low viral loads, and lesser degrees of fibrosis. The course of treatment in all patients who have relapsed after prior therapy should be reviewed to identify possible reasons for failure to achieve an SVR. In particular, optimal dosing of PEG IFN and RBV and the occurrence and timing of treatment dose reductions during prior therapy should be reviewed. The reasons for dose reduction should be addressed before initiating another course of therapy in an effort to optimize the chance for a SVR. Patients who had dose reduction for depression, anemia, or neutropenia, should be considered for antidepressants, erythropoietin, or, if neutropenia is severe, granulocyte colony stimulating factor therapy, respectively, during retreatment. Prolongation of therapy beyond 48 weeks in patients with relapse after a standard course of PEG IFN and RBV may offer a chance of SVR. Novel agents currently in development, including protease and polymerase inhibitors, may prove to be therapeutic options for these patients in the future.

A 2-year-old, Quarter Horse filly was referred to Michigan State University, Veterinary Teaching Hospital with a 2-3 day history of depression and partial anorexia progressing to severe, watery diarrhea with severe neurologic abnormalities, including repetitive muscle fasciculations, muscle stiffening, and collapse. Laboratory findings included severe polycythemia, neutropenia, metabolic acidosis, and electrolyte and fluid loss, consistent with watery diarrhea and endotoxic shock. Increased creatine kinase and aspartate transaminase activities were consistent with recent transport and the muscle abnormalities. Severe hyperammonemia (1369.0 micromol/L; control value, 15.3 micromol/L) was found, without other substantial laboratory evidence of hepatic dysfunction. The horse was euthanized because of poor prognosis and rapid clinical deterioration. Necropsy findings were unremarkable with the exception of severe diffuse colitis. Culture of colonic contents recovered >1000 colony-forming units of Clostridium perfringens. Based on these findings, marked hyperammonemia in this filly was attributed to changes in colonic flora leading to increased bacterial production of ammonia that was readily absorbed through the inflamed bowel wall, exceeding the hepatic capacity for deamination. Intestinal bacteria as a source of hyperammonemia in the absence of hepatic disease has been linked rarely to positive culture results for clostridial organisms.

A 23-year-old Thoroughbred gelding was referred for the evaluation of acute onset of ataxia and depression, and a 2-day history of fever. On physical examination, the gelding was profoundly depressed and 10-12% dehydrated. The horse appeared very unstable, with a wide-based stance in the hind limbs, severe symmetric ataxia in all 4 limbs, and proprioceptive deficits in both hind limbs. Nasogastric intubation produced 4 L of brown, fetid reflux, and rectal examination revealed mild small intestinal and cecal distention. Hematologic abnormalities included neutropenia with toxic change, compatible with acute inflammation and endotoxemia, and prolonged coagulation times. Serum biochemical abnormalities included prerenal azotemia. metabolic acidosis, and electrolyte abnormalities consistent with enteritis. Blood ammonia concentration was markedly increased (406 micromol/L; reference interval 4-49 micromol/L), however, serum bile acids concentration and hepatic enzyme activities were within reference intervals. Histopathologic examination of a liver biopsy revealed no abnormalities and results of tests for several infectious agents were negative. Clinical signs resolved with correction of the dehydration and electrolyte abnormalities and with antibiotic therapy. The horse was diagnosed with hyperammonemic neuropathy associated with gastrointestinal disease. In such cases, hyperammonemia is caused by increased production of ammonia by organisms in the gastrointestinal tract in combination with increased gut permeability that facilitates ammonia absorption.

A phase-I clinical study of a combination therapy of vinorelbine and capecitabine was conducted in anthracycline- and taxane-pretreated patients with advanced/recurrent breast cancer. The objectives of this study in four medical institutions were to evaluate DLT (Dose Limiting Toxicity) and safety as primary endpoints, and tumor response and pharmacokinetics of vinorelbine as secondary endpoints. One 3-week course of treatment consisted of intravenous vinorelbine on Days 1 and 8 and oral capecitabine on Days 1 to 14, followed by a one-week rest. Vinorelbine was given at 20 mg/m(2) (Level 1) and 25 mg/m(2) (Level 2), and capecitabine was given at 1,650 mg/m(2)/day (in two divided doses, Levels 1 - 2). As the administration at each dose level in 3 patients did not cause DLT, 6 patients were additionally treated with vinorelbine at 25 mg/m(2) and capecitabine at 1,650 mg/m(2)/day (in two divided doses) to confirm safety. The major toxicities were bone marrow depression and gastrointestinal symptoms. In particular, the incidences of grade 3 or greater neutropenia (11 patients) and leukemia (10 patients) were high. They were reversible, however, and not severe enough to discontinue treatment. The response rate was 25.0% (3 PR/12). The combination with capecitabine did not affect the plasma pharmacokinetics of vinorelbine.

This prospective study of chemotherapy-induced neutropenia (CIN) explored the association between the relative grade of neutropenia and symptom burden and quality of life (QOL). Eighty-four adult cancer patients from nine community oncology centers receiving 1 of 13 myelosuppressive chemotherapies were evaluated at days 0, 4, 7, 9, 11, 14, and 21 of their respective first cycle. Neutropenia grade (grade 3/4 vs grades 0 to 2) was determined by serial absolute neutrophil count (ANC) measures. Measures of patient-reported outcomes included the Rotterdam Symptom Checklist (RSCL), Hospital Anxiety and Depression Scale (HADS), Cancer Care Monitor-Medical Isolation Scale (CCM-MIS), and SF-36. Changes in outcomes from baseline to highest grade of neutropenia were evaluated using mixed model-repeated measures for each of 15 outcomes. Compared with grades 0-2, grade 3/4 neutropenia was associated with greater symptom burden and worse QOL for six measures (P < 0.05). The pattern of differences suggested that measures of symptom distress and social functioning were sensitive to patient changes associated with grade 3/4 neutropenia. Worsening of symptom burden and QOL appears to be associated with severe afebrile neutropenia. A causal relationship between neutropenia and worse symptoms and QOL remains difficult to establish due to the confounding of the effects of neutropenia with other adverse effects of chemotherapy.

Role of palliative medicine for cancer patients has been expanding to even in earlier stage of disease. We have various new drugs in palliation of symptoms and signs, such as severe pain due to tumor invasion, depression, nausea and vomiting, chemotherapy-induced anemia and neutropenia, etc. Recently pharmacogenomics and drug metabolism became to be focused in cancer treatment. It may cause unexpected toxicity due to drug-drug interaction and may raise unreasonably lower effect due to individual heterogeneity of drug metabolism. To facilitate and maintain better-quality palliative medicine allover Japan, a well-organized educational system and multi-institutional research groups should be established on the basis of a large academic and clinical association. The Japanese Society of Palliative Medicine (JSPM) is one of the candidate of these tasks. The JSPM consists with more than 4,900 members of doctors, nurses and other health professionals who are working in palliative cancer medicine. They have conducting to make guidelines for each symptom control and to increase lobby action to establish efficient networks of palliative cancer medicine in each district of Japan within several years.

Care of patients with cancer can be enhanced by continued involvement of the primary care physician. The physician's role may include informing the patient of the diagnosis, helping with decisions about treatment, providing psychological support, treating intercurrent disease, continuing patient-appropriate preventive care, and recognizing and managing or comanaging complications of cancer and cancer therapies. Adverse effects of therapy and cancer-related symptoms include nausea, febrile neutropenia, pain, fatigue, depression, and emotional distress. 5-Hydroxytryptamine antagonists are effective in controlling acute nausea associated with chemotherapy. Febrile neutropenia requires systematic evaluation and early empiric antibiotics while awaiting culture results. Cancer-related pain, depression, and fatigue often are underdiagnosed and undertreated. Use of brief screening tools for assessing fatigue and emotional distress can improve management of these symptoms. Exercise prescription, activity management, and psychosocial interventions are useful in treating cancer-related fatigue. The physician must be alert for signs and symptoms of cancer-related emergencies like spinal cord compression, hypercalcemia, tumor lysis syndrome, pericardial tamponade, and superior vena cava syndrome.

Chronic C hepatitis is a global health problem. Its treatment is still unresolved. Pegylated interferon means substantive breakthrough in therapy. The longer effect, the lasting, steady therapeutic blood level are the pharmacokinetic advances. There is no significant difference in the side effects of pegylated interferon and standard interferon. The most frequent side effects leading to dose reduction or cessation of the treatment are depression and hematologic disorders. Neutropenia is induced more frequently by pegylated interferon, than by the standard form according to the literature. Combined antiviral treatment (pegylated interferon alpha-2a and ribavirin) of a 54 years old woman, who suffered from posttransfusion chronic hepatitis C was started. The dose of the pegylated interferon alpha-2a and ribavirin was reduced at the 8th week due to leucopenia and mild anemia. Fever, cough, sore throat and weakness occurred. Agranulocytosis was detected which was accounted as a side effect of pegylated interferon treatment. Antibiotic, antimycotic therapy and filgastrim was given. Leukocyte number increased, fever stopped after 10 days of therapy. The patient returned 17 days later. She had been having high fever, weakness, sore throat for 4 days. Ciprofloxacin was given by GP before her registration because of the suspicion of urinary infection, then she took sulfamethoxazol + trimethoprim without medical advise. Agranulocytosis was detected again, Staphylococcus sepsis developed. No sign of hematologic disease was found in the bone marrow. Agranulocytosis was considered aftermath of sulfamethoxazol + trimethoprim. Antibiotics, antimycotic and antiviral treatment, and filgastrim were given, sepsis healed, leukocyte number became normal. 274 patients suffering from chronic hepatitis C were treated by standard interferon, and 43 were treated by pegylated interferon. Rapid and significant decrease of leukocyte count was observed in the patients treated by pegylated interferon in the first 4 weeks of the treatment then it remained stable. Cessation of the treatment or dose-reduction was not necessary due to neutropenia among patients treated by standard interferon, while dose reduction was reasonable in two more cases in addition to this one, treated by pegylated interferon. The authors stress the importance of the exact follow-up of patients according to the protocol, which renders the early recognition of side effects, the prevention of complications, and their early and adequate treatment possible. Thus, pegylated interferon--inspite of its marked side effects and more serious suppressive effect on bone marrow--is the most effective drug for the treatment of chronic hepatitis C.
