AbstractThis report describes a case of canine hemotropic mycoplasmasosis by Candidatus Mycoplasma haematoparvum in a dog. A five-year-old splenectomized dog was referred to the Veterinary Teaching Hospital of the University of Sassari with clinical symptoms and laboratory findings compatible with immune-mediated hemolytic anemia. Epicellular bacteria were detected in the erythrocytes by microscopic examination of blood smears. PCR and sequencing were positive for Candidatus Mycoplasma haematoparvum. Treatment with doxycycline, prednisolone and blood transfusion was administered. Several studies have described the molecular prevalence of M. hemocanis and Candidatus M. haematoparvum, however there are few clinical reports, especially those describing Candidatus M. haematoparvum infection in dogs, for which only two cases have been reported. To the best of our knowledge this is the first case report of a symptomatic infection caused by Candidatus Mycoplasma haematoparvum in Italy. Hemoplasmosis should be considered as a potential cause of hemolytic anemia in dogs. Following treatment with doxycycline and prednisolone, the clinical signs improved without resolution of infection. This condition was the same at the three-year follow-up.

A 23-year-old pregnant warmblood mare from Güssing, Eastern Austria, presented with apathy, anemia, fever, tachycardia and tachypnoea, and a severely elevated serum amyloid A concentration. The horse had a poor body condition and showed thoracic and pericardial effusions, and later dependent edema and icteric mucous membranes. Blood smear and molecular analyses revealed an infection with Theileria equi. Upon treatment with imidocarb diproprionate, the mare improved clinically, parasites were undetectable in blood smears, and 19 days after hospitalization the horse was discharged from hospital. However, 89 days after first hospitalization, the mare again presented to the hospital with an abortion, and the spleen of the aborted fetus was also PCR-positive for T. equi. On the pasture, where the horse had grazed, different developmental stages of Dermacentor reticulatus ticks were collected and subjected to PCR, and one engorged specimen was positive for T. equi. All three amplicon sequences were identical (T. equi genotype E). It is suspected that T. equi may repeatedly be transmitted in the area where the infected mare had grazed, and it could be shown that transmission to the fetus had occurred. Due to the chronic nature of equine theileriosis and the possible health implications of infection, it is advised to include this disease in the panel of differential diagnoses in horses with relevant clinical signs, including horses without travel disease, and to be aware of iatrogenic transmission from inapparent carrier animals.

Abstract Background Enlargement of the prostate is associated with prostatic diseases in dogs, and an estimation of prostatic size is a central part in the diagnostic workup. Ultrasonography is often the method of choice, but biomarkers constitute an alternative. Canine prostate specific esterase (CPSE) shares many characteristics with human prostate specific antigen (PSA) and is related to prostate size. In men with clinical symptoms of prostatic disease, PSA concentrations are related to prostate growth. The aims of the present follow-up study were to evaluate if the concentration of CPSE is associated with future growth of the prostate, and if analysis of a panel of 16 steroids gives further information on prostatic growth. Owners of dogs included in a previous study were 3 years later contacted for a follow-up study that included an interview and a clinical examination. The prostate was examined by ultrasonography. Serum concentrations of CPSE were measured, as was a panel of steroids. Results Of the 79 dogs included at baseline, owners of 77 dogs (97%) were reached for an interview, and 22 were available for a follow-up examination. Six of the 79 dogs had clinical signs of prostatic disease at baseline, and eight of the remaining 73 dogs (11%) developed clinical signs between baseline and follow-up, information was lacking for two dogs. Development of clinical signs was significantly more common in dogs with a relative prostate size of ≥2.5 at baseline (n = 20) than in dogs with smaller prostates (n = 51). Serum concentrations of CPSE at baseline were not associated with the change in prostatic size between baseline and follow-up. Serum concentrations of CPSE at baseline and at follow-up were positively associated with the relative prostatic size (Srel) at follow-up. Concentrations of corticosterone (P = 0.024), and the class corticosteroids (P = 0.0035) were positively associated with the difference in Srel between baseline and follow-up. Conclusions The results support the use of CPSE for estimating present and future prostatic size in dogs ≥4 years, and the clinical usefulness of prostatic size for predicting development of clinical signs of prostatic disease in the dog. The association between corticosteroids and prostate growth warrants further investigation.

The Impact

Abstract Background Since the novel coronavirus disease outbreak, over 179.7 million people have been infected by SARS-CoV-2 worldwide, including the population living in dengue-endemic regions, particularly Latin America and Southeast Asia, raising concern about the impact of possible co-infections. Methods Thirteen SARS-CoV-2/DENV co-infection cases reported in Midwestern Brazil between April and September of 2020 are described. Information was gathered from hospital medical records regarding the most relevant clinical and laboratory findings, diagnostic process, therapeutic interventions, together with clinician-assessed outcomes and follow-up. Results Of the 13 cases, seven patients presented Acute Undifferentiated Febrile Syndrome and six had pre-existing co-morbidities, such as diabetes, hypertension and hypopituitarism. Two patients were pregnant. The most common symptoms and clinical signs reported at first evaluation were myalgia, fever and dyspnea. In six cases, the initial diagnosis was dengue fever, which delayed the diagnosis of concomitant infections. The most frequently applied therapeutic interventions were antibiotics and analgesics. In total, four patients were hospitalized. None of them were transferred to the intensive care unit or died. Clinical improvement was verified in all patients after a maximum of 21 days. Conclusions The cases reported here highlight the challenges in differential diagnosis and the importance of considering concomitant infections, especially to improve clinical management and possible prevention measures. Failure to consider a SARS-CoV-2/DENV co-infection may impact both individual and community levels, especially in endemic areas.

Case summary This paper presents two cases of acute postoperative upper airway obstruction following ventral bulla osteotomy (VBO) in cats. The first cat underwent a unilateral left-sided VBO for a suspected inflammatory polyp. The second cat underwent a single-session bilateral VBO procedure for bilateral otitis media. In the first case, immediate re-intubation and a gradual lightening of the anaesthetic plane resolved the clinical signs; in the second case, the patient deteriorated and went into acute cardiorespiratory arrest and received cardiopulmonary resuscitation. Both patients recovered well and were discharged home 3 days after surgery. Both cases were reported to show no further clinical signs on postoperative follow-up 3 weeks and 4 months after surgery, respectively. Relevance and novel information Upper airway obstruction should be regarded as a potential complication of VBO in cats.

First Case

Abstract Abstract 5276 Pyruvate kinase (PK) deficiency of red cells (EC: 2.7.1.40) is the commonest inherited enzyme deficiency in the glycolytic pathway, leading to chronic non-spherocytic hemolytic anemia (CNSHA). There are over 220 characterized mutations deposited in a public database (PKLR Mutation Database http://www.pklrmutationdatabase.com). Heterozygous carriers are asymptomatic but homozygotes or compound heterozygotes can have significant anemia leading to transfusion dependency, neonatal death and hydrops fetalis. All ethnic groups are affected but data on Chinese are very scanty. We describe the first case of prenatal diagnosis for PK deficiency in Chinese and emphasize that this disease is an important differential diagnosis in pediatric patients with hemolytic anemia. A Han Chinese presented with hepatosplenomegaly, severe anemia and unconjugated hyperbilirubinemia at birth, necessitating exchange transfusion on day 1 and prolonged phototherapy till day 10 of life. Glucose-6-phosphate dehydrogenase level was normal. His parents were unrelated and asymptomatic. Family history was unremarkable. He developed severe CNSHA on follow up, requiring monthly red cell transfusion to relieve symptoms and to maintain satisfactory growth. Iron chelation therapy was started at 2 years of age and splenectomy was performed at 4 years to reduce transfusion requirement. The baseline PK enzyme level was not known but both parents had a mildly reduced PK level. Genetic analysis of PKLR gene was performed. All 11 exons and promoter were screened using polymerase chain reaction (PCR)-denaturing high performance liquid chromatography followed by PCR-sequencing. The father was found to carry a mutation in exon 8: PKLR: c.1073 G>A (p.Gly358Glu) while the sequencing result was normal in the mother. Quantitative multiplex PCR of short fluorescent fragments detected a rare large deletion removing exon 4 to exon 10 of the PKLR gene in the mother. Gap-PCR mapping confirmed that it to be a deletion previously found in a Vietnamese family (Costa C et al Haematologica 2005) and an Australian family (Fermo E et al Br J Haematol 2005). Both mutations have not been previously reported in Chinese. The proband was found to carry the paternal point mutation and the maternal deletion. Because of the severe clinical course of their first child, the couple requested prenatal biopsy was performed at 12 week of gestation. The fetus was found to be simple heterozygous for the paternal mutation. Pregnancy was allowed to continue and a healthy baby was born. A PK assay performed at the age of 9 months was normal. Mutation studies in a peripheral blood sample at 10 months of age confirmed the PKLR genotype. There was no evidence of hemolytic anemia after 3 years of follow up. Because of its perceived rarity and benignity in many ethnic groups, PK deficiency does not enter early into the differential diagnosis of anemia in pediatric patients. Its potential to cause severe disease is often overlooked and delay in diagnosis is common (Pissard S et al J Pediatr 2007). Genetic characterization and genotype-phenotype correlation studies on PKLR in different populations are indicated to better characterize the disease spectrum and to define the role of prenatal diagnosis in PK deficiency.

Anaplasma (A.) phagocytophilum, the etiological agent of canine granulocytic anaplasmosis, is capable of inciting moderate to severe clinical disease in a variety of mammals and is endemic in the upper midwest. The purpose of this study was fourfold: to describe the range of clinical signs in dogs seropositive to A. phagocytophilum; to examine the prevalence of immune-mediated hemolytic anemia (IMHA) in this population; to evaluate whether specific clinical signs were associated with coexposure to Borrelia (B.) burgdorferi in actively infected dogs; and to determine whether clinical response to doxycycline was complete in treated dogs. Medical records of dogs seropositive for A. phagocytophilum were reviewed retrospectively. Peripheral blood smears were also reviewed retrospectively for granulocytic Anaplasma morulae. Lethargy (81%), inappetence (58%), and lameness (50%) were the most common clinical signs, followed by fever (46%). Thrombocytopenia was the most common laboratory abnormality, and IMHA was diagnosed in three dogs. Dogs that were thrombocytopenic and had antibodies to both A. phagocytophilum and B. burgdorferi had a median platelet count of 51,000/μL (range 20,000 to 171,000/μL), which was significantly lower than the count in dogs with antibodies only to A. phagocytophilum (P=0.04). Some dogs had an apparent relapse of clinical signs after an appropriate course of doxycycline. Testing for A. phagocytophilum by polymerase chain reaction, serum antibody assays, and/or blood smear evaluation should be considered in dogs with IMHA, cough, or epistaxis and that reside in A. phagocytophilum-endemic areas. If moderate to severe thrombocytopenia is present, testing for concurrent B. burgdorferi infection may be warranted.

The local slaughterhouse’s coronavirus cluster was the first large outbreak we heard about in Champaign County. The sprawling pork processing plant sits in the midst of cornfields some 17 miles north of the University of Illinois at Urbana-Champaign. Until early May, workers there processed 35 million pounds of pork a month. The company reported its first case on 25 April. Health inspectors arrived two days later to find the plant 90 percent out of compliance in its infection control practices. By 15 May, after testing 200 of the 627 workers for COVID-19, 83 got positive results. Management admitted it was ‘complex’ to track employees being tested and to follow up with those who had to be quarantined. That’s when they contacted the University of Illinois at Urbana-Champaign. They then announced confidently to the local press: We’ve got it under control. We have the scientists now.

Background: Immune thrombocytopenia (ITP) is an acquired immune mediated disorder characterized by isolated thrombocytopenia. Pediatric ITP patients can develop autoantibodies such as anti-thyroglobulin (TG) and anti-thyroperoxidase (TPO), even in the absence of clinical signs of autoimmune disease. Objective: The purpose of this article is to provide a review about: 1) the prevalence of positivity of anti-thyroid antibodies (TPO and TG) in pediatric patients with chronic ITP; 2) the role of autoimmune thyroiditis on the outcome of chronic ITP. Method: The authors individually completed a review of the literature for this article. Retrospective and prospective clinical studies with pediatric cohorts were considered. Results: From the analysis of data, we found 4 papers which included studies only on pediatric population, and which corresponded to selected criteria. Pediatric ITP patients have been shown to have a statistically significant prevalence of anti-thyroid antibodies over healthy controls (11.6-36% versus 1.2-1.3%). No correlation has been found between the platelet count and the prevalence of positive anti-thyroid antibodies at any time of the follow up. Conclusion: The results of our bibliographic research demonstrated that: a) pediatric patients with chronic ITP tend to have a statistically significant prevalence of anti-thyroid antibodies positivity respect to general pediatric population; b) there are no clear data about the role of autoimmune thyroiditis as prognostic factor for chronic course of ITP in pediatric age.

Rosai-Dorfman disease (RDD) manifesting as a solitary osseous lesion especially of talus bone is rare. The authors reported a 31-year-old Thai man who had chronic left ankle pain and the biopsy of his talar lesion demonstrated emperipolesis, the typical histological feature of RDD. He was treated with curettage and adjuvant bisphosphonate and appeared to show improvement in clinical symptoms and radiological evidence. To the authors’ knowledge, this is the first report of an intraosseous RDD lesion treated with bisphosphonate with imaging follow-up.

Abstract Patients: The 3 patients detailed in this report presented to Ohio State University Hospitals and were enrolled on our prospective study of plasma exchange as initial therapy of TTP. Given the close outpatient follow-up during the first month after the tapering of plasma exchange, 2 patients were found to have an early recurrence of their TTP. The third patient had a recurrence 8 weeks after completing 6 months of CSA after being treated with concurrent CSA and PE for a previous acute episode of TTP. She completed the planned 6 months of cyclosporine therapy but relapsed 8 weeks after discontinuing the drug. Her recurrence was characterized by numbness and tingling in her right hand in addition to laboratory findings consistent with TTP. Complete demographic and clinical details of these 3 patients are shown in Table 1. Methods: All 3 patients received oral cyclosporine (2–3 mg/kg) daily for six months in a divided dose. None of the patients underwent plasma exchange, infusion, or transfusion of blood products of any kind. Patients were seen daily to monitor for any clinical or laboratory findings that would warrant the re-initiation of plasma exchange therapy. Remissions were defined as a normal platelet count, normalization of LDH for at least 2 consecutive days, and improvement or stabilization of any renal and neurologic abnormalities. Serial measurements of ADAMTS13 activity and inhibitors were performed at regular intervals throughout therapy and follow-up. Results: All three patients showed clear laboratory and clinical signs of improvement within the first 7 days of therapy and met criteria for clinical remission 14, 24, and 34 days respectively from the time they began treatment with cyclosporine. The third patient that presented with numbness and tingling in her right hand also had complete resolution of her neurologic symptoms within one week of restarting cyclosporine. Pretreatment ADAMTS13 activity was determined to be 33%, 25%, and 10% in all 3 patients respectively with all 3 patients having documented inhibitors of ADAMTS13. Conclusions: Treatment with cyclosporine alone resulted in the suppression of ADAMTS13 inhibitors and normalization of ADAMTS13 activity. Figure Figure All three patients have completed the planned 6 months of cyclosporine and have maintained their remission 4, 3, and 1 month respectively after discontinuing cyclosporine.
