Using the haemagglutination inhibition and immunodiffusion tests, a national serological survey was carried out to detect antibodies to equine influenza (EI) (A/equi/1/Prague 56 and A/equi/2/Miami 63) and equine infectious anaemia (EIA) in horse sera collected in northeastern Tunisia. 533 samples were analysed for EIA antibodies. All were negative. 13.6% of 433 equine sera tested for EI antibodies were positive. These results are discussed and compared with others obtained in Tunisia and bordering countries.

We describe the clinical and laboratory findings of 7 adult patients with serological evidence of recent human parvovirus B19 (HPV) infection who presented with generalized edema. Six of the 7 patients had household contact with children with erythema infectiosum and had flu-like symptoms before visiting hospital. The interval between the flu-like episode and the development of edema ranged from 4 to 13 days (mean 7.0). In all 7 patients, there was serological confirmation of recent HPV infection, and all showed the development of edema following HPV infection without urine abnormalities or anemia. Two patients presented hypocomplementemia, and two patients showed signs of congestive heart failure. HPV may be considered a causative agent of generalized edema not only in the fetus but also in adults and HPV infection should be included in the differential diagnosis of generalized edema formation.

Interferon-alpha (IFN-alpha) can inhibit human immunodeficiency virus (HIV-1) replication and is effective in treating Kaposi's sarcoma; interleukin-2 (IL-2) can increase circulating lymphocytes in HIV-1-infected patients. The safety of combination treatment with recombinant (r)IFN-alpha 2b and IL-2 was evaluated in HIV-1-infected patients with > 200 CD4+ T cells/mm3. A maximal tolerated dose of rIFN-alpha 2b was determined for 17 patients; then they received in combination 3, 6, or 12 x 10(6) IU/day rIL-2, given intravenously over 21 days. Twelve patients ultimately received the combination, 9 for the full 21 days. Significant toxicities included flu-like symptoms, anemia, transaminemia, and depression. Transient increases in CD4+ T cell percentages and spontaneous lymphocyte blast transformation were observed. Quantitative microcultures demonstrate a decline in HIV titers in patients receiving rIFN-alpha 2b (5/9) with a further decline on addition of rIL-2 (7/9). In summary, continuous rIL-2 at 6 x 10(6) IU/day in combination with rIFN-alpha 2b was reasonably tolerated and provided preliminary evidence of immunomodulatory and antiviral activity.

Erythropoietin has been shown to be effective both in the reversal of anaemia in patients with end-stage renal failure and to increase the volume of autologous red blood cells donated preoperatively as well as to decrease the units of homologous blood transfused. This review analyzes the side effects of erythropoietin reported in the literature for long-term administration (mainly in patients with end-stage renal failure) as well as for acute/short-term administration (in patients participating in an autologous predeposit programme). The most important adverse events reported for long-term administration are as follows: (a) arterial hypertension; (b) cerebral convulsion/hypertensive encephalopathy; (c) thrombo-embolism; (d) iron deficiency; (e) influenza-like syndrome. The numbers given for these side effects are mainly taken from the first and dose-finding studies in patients with renal failure. These figures differ very much from the data given in controlled studies analyzing adverse events as well. Summarizing the results from controlled, multi-center trials in patients with end-stage renal failure or in AIDS patients, no significant differences have been observed between the control group and the patients treated with erythropoietin. The overall-incidence of side effects occurring in either group of these two studies was of approximately 83% and 95%, respectively. In contrast to these results the data published for the dose finding/treatment studies is approximately 30% for development of arterial hypertension, approximately 5% for occurrence of cerebral convulsion/hypertensive encephalopathy, approximately 10% for thrombo-embolic complications/clotting of vascular access, approximately 50% for development of iron deficiency, and approximately 10% for symptoms summarized as influenza-like syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)

Autoimmune hemolytic anemia may occur in the course of some viral diseases such as Coxsackie virus, cytomegalovirus, Epstein Barr virus, Influenza A, herpes simplex virus, and rarely hepatitis B virus infection. The role of being heterozygous for beta-thalassemia in hemolysis during acute viral hepatitis is not known. In this report, we present an eight-year-old boy with jaundice and anemia. The diagnosis of hepatitis B virus infection and hemolytic anemia were made on the basis of physical and laboratory findings. A hemoglobin electrophoresis revealed that the child was heterozygous for beta-thalassemia. No specific etiology could be found for hemolytic anemia. It remained unclear whether hemolytic anemia in this patient was merely a coincidental finding or whether hepatitis B virus infection and beta-thalassemia trait had played a role in causing hemolysis.

The effect of recombinant human erythropoietin therapy on correction of renal anaemia was evaluated. A total of 100 patients with endstage renal disease and anaemia (level of haemoglobin < 9.6 g/dl) received erythropoietin for 125 patient years. In 81 patients the level of haemoglobin increased to the intended range (10.5-12.0 g/dl) within three to four months. In 16 of the patients acute infections were followed by a temporary reduction in the haemoglobin level. In 11 patients a previous transfusion requirement was reduced, or, in most cases, abolished. In the remaining eight patients the transfusion requirement was unchanged. The patients with either a sub-optimal or no response suffered from chronic infections, malignant diseases or recurrent bleeding episodes. In 28 patients the level of haemoglobin exceeded the intended target for a period of four months (average). Serious side effects were not observed. Six patients had 'flu-like symptoms after the first injections. Three cases of thrombosis of the arterio-venous fistula were observed in two patients. The frequency of thrombosis of the vascular access did not exceed what we expected to find.

Seventy-five non-dialized patients with chronic renal failure (CRF) and severe renal anemia were enrolled in a study, receiving r-HuEPO subcutaneously thrice weekly for 6 months. In 64 patients (85%) 7 weeks of treatment with a weekly dose of 158 U/kg were required to achieve Hb concentrations within the target range of 10 to 12 g/dl. Of the 11 patients (15%) who failed to achieve the target Hb range, none were considered to be non-responders as they were excluded for unrelated reasons prior to week 16 (8 cases), or were iron deficient (2 cases), or had bleeding complications (1 patient). Maintaining the Hb concentration at a level of 10.5 g/dl required a mean r-HuEPO dose of 92 U/kg per week. Adverse events were generally mild or moderate. The most commonly reported were hypertension (8%), viral infection/including flu-like syndrome (7%), nausea (7%), and dizziness (5%). Statistically significant increases in mean creatinine concentrations observed after 12 and 24 weeks were most likely due to the progression of renal disease. These results confirm that 50 U/kg of r-HuEPO given 3 times per week subcutaneous provide a safe and effective therapy for anemic predialysis patients.

Forty patients with AIDS-associated Kaposi's sarcoma (KS) treated with the combination of interferon alpha-2b (IFN-alpha) 10-20 MU day-1 and zidovudine (ZDV), 500-800 mg day-1, were evaluated for safety and efficacy. Eighteen patients (45%) had an overall response (CR+PR) at 3 months and a response persisting for a median of 14 (3-27) months. Patients with a CD4 count of less than 300 mm-3, prior to opportunistic infections or constitutional symptoms, were less likely to respond. However, between 28.5% and 36% of patients with a low CD4 count did respond to combined therapy. This is higher than would be predicted from single agent IFN-alpha therapy. Twelve of 28 patients (42.8%) receiving 10 MU day-1 of IFN-alpha (low dose) had an overall response. In addition, patients tolerated this dose of IFN-alpha better, presenting fewer flu-like symptoms and displayed a trend toward less anaemia. p24 antigen decreased in six out of nine evaluable cases, four of whom were treated with low-dose IFN-alpha. Low-dose IFN-alpha plus ZDV seems to be a useful and well-tolerated therapy for KS with antitumoral and antiviral activity. Patients without 'bad prognostic markers' are most likely to show improvement.

Interferons have been shown to increase in vitro cytotoxicity of platinum compounds. The Hoosier Oncology Group has conducted a Phase II clinical trial to determine if interferon alpha-2a (IFN-alpha-2a) given in combination with carboplatin (CBDCA) can increase response rates or survival in patients with metastatic or recurrent inoperable non-small-cell lung cancer. Forty-four patients with no prior chemotherapy and high KPS (80-100) were enrolled. CBDCA 400 mg/m2 was given intravenously on day 1 and IFN-alpha-2a 9 million units was given subcutaneously on days 1, 3, and 5. Treatment was administered every 4 weeks until onset of progressive disease or to a maximum of 4 courses: 37 patients (84%) received at least 2 courses, whereas only 16 (36%) received the full 4 courses. Dose-limiting toxicities were leukopenia (27%) and thrombocytopenia (20%) attributable to CBDCA. Grade 2-3 anemia occurred in 32%. Only 4-7% of patients experienced severe fever, fatigue, or flu-like symptoms attributable to interferon administration. Of 41 patients evaluable for response, there were no complete responses and only 3 (7.3%) partial remissions. The overall median survival was 6 months. The combination of CBDCA and IFN-alpha-2a given in this dose and schedule does not appear to have superior activity compared to CBDCA alone in patients with non-small-cell lung cancer.

Amonafide, a benzisoquinoline-1,3-dione was administered to 38 patients with recurrent or metastatic, bidimensionally measurable endometrial cancer. There were 34 patients with no prior cytotoxic chemotherapy, performance status of 0-2, and normal bone marrow, renal, and hepatic function were eligible for response and toxicity evaluation. Amonafide, 300 mg/m2, was administered intravenously over 1 hour daily for 5 consecutive days. Courses were repeated every 21 days. The major grade 3 or 4 toxicities were hematologic with granulocytopenia in 18 patients (53%), thrombocytopenia in 6 patients (18%), and anemia in 8 patients (24%). Infectious complications occurred in 3 patients (9%). Other side effects included cardiac dysrhythmias, hypotension, pain and phlebitis at the site of injection, nausea, vomiting, and flu-like symptoms. The overall objective response rate was 6% (95% confidence interval of 1-20%); 2 patients had a complete response (6%), 9 patients had stable disease (26%) and 21 patients had progressive disease (62%). Two patients had insufficient follow-up for response determination and are assumed to be nonresponders. The median survival of the eligible patients was 8 months. With the toxicity observed and the low response rate, amonafide at this dose and schedule has no efficacy in the treatment of endometrial cancer.
