We report herein a 61-year-old man with chronic cold agglutinin disease which occurred after a diagnosis of aplastic anemia. The patient's pancytopenia was recognized upon visiting a local doctor because of high fever and cough on December 21, 1985. He was subsequently admitted to our hospital because of anasarca on January 31, 1986, and was diagnosed as having aplastic anemia. He was treated with prednisolone, and was discharged after his anemia improved. He was readmitted on October 23, 1988, because of icterus. Laboratory data on the patients second admission revealed increased reticulocyte count, hyperplastic bone marrow with a predominance of erythroblasts, increased serum indirect bilirubin, increased serum LDH1 value and decreased serum haptoglobin. Moreover, cold agglutinin titer was increased, anti-IF antibody was positive, and anti-IgM antibody was recognized with direct anti-globulin test. There was no precedent infection such as mycoplasma pneumonia or infectious mononucleosis. Hence, this patient was diagnosed as having chronic cold agglutinin disease.

The tetracyclines are effective in the treatment of Chlamydia, Mycoplasma pneumoniae, and rickettsial infections and also can be used for gonococcal infections in patients unable to tolerate penicillin. These drugs may cause gastrointestinal irritation, diarrhea, phototoxic dermatitis, and vestibular damage, and fatal reactions due to hepatotoxicity have occurred in pregnant women. Chloramphenicol has a broad spectrum of bacteriostatic activity, but its association with suppression of the bone marrow and aplastic anemia has relegated it to a historical role. Erythromycin is the drug of choice for the treatment of infections caused by M. pneumoniae, Legionella species, group A beta-hemolytic streptococci, and Streptococcus pneumoniae. The frequency of serious adverse effects associated with the use of erythromycin is low; dose-related epigastric distress may occur. Clindamycin is bactericidal to most nonenterococcal gram-positive aerobic bacteria and many anaerobic microorganisms. Although historically it was a frequent cause of antibiotic-associated diarrhea and colitis, clindamycin is considered an excellent alternative to beta-lactam antibiotics for treatment of many staphylococcal infections, and it has therapeutic utility in anaerobic infections and in several protozoan infections in immunosuppressed patients. Metronidazole is efficacious for treating nonpulmonary anaerobic infections, various parasitic infections (trichomoniasis, amebiasis, and giardiasis), nonspecific vaginitis, and Clostridium difficile-mediated colitis. With use of metronidazole, mild side effects such as epigastric discomfort, diarrhea, reversible neutropenia, and allergic-type cutaneous reactions may occur.

Antiviral humoral immunity was studied in patients with Hodgkin's disease, idiopathic thrombocytopenic purpura (ITP), and aplastic anemia (AA). Insufficiency of antiviral humoral immunity as regards antigenically unrelated viruses and Mycoplasma pneumoniae was characteristic of all these conditions. A remission of Hodgkin's disease and ITP was associated with a reliable increase of the studied parameters in comparison with the acute period of the disease. After splenectomy humoral immunity parameters were virtually unchanged in patients with ITP, whereas in patients with Hodgkin's disease and AA the deficiency of antibody production is 40% increased after the operation.

Two very unusual cases of aplastic anemia complicating mycoplasma infection are described. Each patient had preexisting hematologic abnormalities at the time of the infection: reactive hemophagocytic syndrome in one, and autoimmune hemolytic anemia associated with cold autoantibodies in the other. This adds another entity to the protean manifestations of Mycoplasma pneumoniae infection.

Coronavirus infection (CVI) was studied in 227 patients hospitalized in the clinic of the Research Institute of Hematology and Transfusiology in 1993-2003 with diagnosed acute and chronic leucosis, multiple myelogenic disease and aplastic anemia. Their blood sera and secretions of the nasal cavity were examined in the indirect hemagglutination (IHA) test with dried standard erythrocyte diagnostic preparations. CVI was shown to be activated in three year cycles in immunodeficient patients, which occurred, respectively, in 66.1, 56.9, 47.8 and 51.6% of cases in the above mentioned groups of patients. In 87% of cases CVI was associated with other respiratory pathogens, the following being prevailed: respiratory syncytial virus (37.9%), parainfluenza virus (32.2%) and Mycoplasma pneumoniae (36.8%). CVI was provoked by such factors as the course of the main disease and specific treatment, previous respiratory infections of other etiology with M. pneumoniae infection playing the leading role (60%). The most severe course of CVI was observed in patients with acute leucosis (in 75% of cases accompanied by lesions of lower respiratory tracts). The use of the highly sensitive IHA test made it possible to determine the potential for both serum and local antibodies production in the patients under observation.

There are a number of newly described and emerging disease syndromes affecting the domestic ferret, and the purpose of this article is to make veterinarians aware of these diseases. A recently described systemic coronavirus infection appears to be a variant of the ferret enteric coronavirus and is currently termed "ferret infectious peritonitis." Disseminated immunopathologic myositis, aplastic anemia/bone marrow aplasia, acute hemorrhagic syndrome, and oral ulcerations are also described, although the exact etiologies for these diseases have yet to be determined. There appears to be at least 2 important amino acid metabolism deficiencies in ferrets: hindlimb weakness in older ferrets (L-carnitine) and cysteine urolithiasis. Ferrets have recently been found to be susceptible to H1N1 influenza, so knowledge regarding this zoonotic disease is essential for veterinarians working with these animals. A novel Mycoplasma spp. has also recently been identified in ferrets with chronic respiratory problems that originated from one breeding colony. Because these diseases are still being investigated, practitioners who treat a ferret patient exhibiting clinical signs consistent with any of the conditions mentioned are encouraged to contact people who are knowledgeable of that particular illness.
