Cytomegalovirus (CMV) is a virus that infects both normal and compromised hosts. In normal hosts, CMV presents most often as an "infectious mononucleosis-like" illness, but less commonly may present as community-acquired pneumonia (CAP), colitis, hepatitis, or fever of unknown origin. In compromised hosts, CMV often presents as CAP, encephalitis, retinitis, adrenalitis, hepatitis, or colitis. Not unlike parvovirus B19, CMV is an immunomodulatory virus that may cause or exacerbate rheumatic/inflammatory disorders, particularly systemic lupus erythematosus (SLE). Acute CMV infection may result in de novo SLE or more commonly may precipitate an SLE flare. In patients with SLE who are taking immunosuppressives, CMV increases the degree of immunosuppression of cell-mediated immunity. We present the case of a 40-year-old woman with SLE who presented with severe CMV CAP. CMV infection was suspected because of 2 nonspecific laboratory findings: increased serum transaminases and atypical lymphocytes in the peripheral smear. SLE is a multisystem autoimmune disorder that spares the liver. Therefore, in a patient with SLE who experiences an SLE flare, increased serum transaminases should suggest the possibility of CMV. In patients with SLE with flare, the likelihood of CMV is further increased if serum transaminases are elevated with atypical lymphocytes and should prompt specific testing for CMV. This patient's severe CMV CAP was treated successfully with oral valganciclovir, and she made a slow but complete recovery.

A 70-year-old Japanese man with chronic kidney disease under treatment with oral prednisolone for organizing pneumonia developed pulmonary aspergilloma. The patient was started on micafungin (MCFG), with no addition of any other new drug. About 5 weeks later, aggravation of his normocytic anemia associated with a low reticulocyte count was observed. Bone marrow puncture and biopsy revealed intense hypoplasia of the erythroblasts. As there was no evidence of malignancy, human parvovirus B19 infection, autoimmune diseases or hemorrhage, the patient was diagnosed as having acquired pure red cell aplasia (PRCA). The anemia improved along with an increase of the reticulocyte count to the normal level within 12 weeks of discontinuation of the MCFG therapy. The patient showed no evidence subsequently of any recurrence of the normocytic normochromic anemia or relapse of the PRCA. This is the first reported case of PRCA associated with MCFG.

A 46-year-old woman was admitted due to diplopia because of ophthalmoplegia, which improved with corticosteroid therapy. Eight days later, she was admitted with fulminant myocarditis in cardiogenic shock, with severe left ventricular dysfunction and frequent episodes of nonsustained ventricular tachycardia. As there was no clinical improvement, an endomyocardial biopsy was performed that revealed inflammatory infiltrate, vasculitis, and PCR positive for cytomegalovirus, Epstein-Barr virus, parvovirus B19 and enterovirus. Left ventricular function recovered with heart failure treatment and corticosteroids. Three months later, after progressive withdrawal of prednisolone, there was recurrence of myocarditis and left ventricular dysfunction, which was successfully treated by restarting corticosteroid therapy. One month later she was readmitted with fulminant myocarditis which again responded to steroids. She intermittently presented cutaneous purpura lesions. At this time the provisional diagnosis was vasculitis and she started monthly cycles of cyclophosphamide. Before the second cycle she was admitted with pneumonia and ventricular dysfunction and died.

Background: Human parvovirus B19 was known as one of the possible cause of mild respiratory tract diseases in previous studies. However, there are some reports of acute obstructive respiratory disease and severe pneumonia. The purpose of current study was to assess the prevalence and clinical features of parvovirus B19 in respiratory infection. Methods: This study was conducted on 156 patients diagnosed with respiratory infection at the Iran University of Medical Sciencesaffiliated hospitals. After extraction of viral DNA from swab samples, detection of parvovirus B19 was performed by real-time PCR assay. Results: In 156 patient's samples, parvovirus B19 was found in 8 (5.1 %) cases including 5 males (5.9%) and 3 females (4.1%). The most common clinical symptoms were wheezing (100%), tachypnea (100%), fever (75%) and rhinorrhea/pharyngitis (75%). Conclusion: This is the first attempt to assess the prevalence of parvovirus B19 infection in Iranian patients with respiratory infection. The low frequency of parvovirus B19 detected in our study does not support the role of this virus in the development of respiratory infection. However, further studies are needed to better evaluate the etiological role of parvovirus B19 in respiratory infection.

Febrile illness is a major burden in African children, and non-malarial causes of fever are uncertain. In this retrospective exploratory study, we used metagenomic next-generation sequencing (mNGS) to evaluate serum, nasopharyngeal, and stool specimens from 94 children (aged 2-54 months) with febrile illness admitted to Tororo District Hospital, Uganda. The most common microbes identified were Plasmodium falciparum (51.1% of samples) and parvovirus B19 (4.4%) from serum; human rhinoviruses A and C (40%), respiratory syncytial virus (10%), and human herpesvirus 5 (10%) from nasopharyngeal swabs; and rotavirus A (50% of those with diarrhea) from stool. We also report the near complete genome of a highly divergent orthobunyavirus, tentatively named Nyangole virus, identified from the serum of a child diagnosed with malaria and pneumonia, a Bwamba orthobunyavirus in the nasopharynx of a child with rash and sepsis, and the genomes of two novel human rhinovirus C species. In this retrospective exploratory study, mNGS identified multiple potential pathogens, including 3 new viral species, associated with fever in Ugandan children.

Refractory viremia/viral disease is a major life-threatening complication that may arise among patients undergoing allogeneic hematopoietic cell transplantation (allo-HCT). This study aimed to clarify the therapeutic effect of high-dose polyclonal intravenous immunoglobulin (IVIG) against viremia/viral diseases after allo-HCT. We conducted a pilot study to investigate the therapeutic effect of 400 mg/kg of IVIG given for 5 consecutive days against refractory viremia/viral disease after allo-HCT. Overall, 7 patients were drug-resistant and the other 7 had not previously received any drug for their viremia/viral disease. All patients completed the 5-day therapy regimen of IVIG. A complete response at Day 56 was observed for 8 of 14 patients (57.1%). Additionally, 10 of 14 patients (71.4%) were alive at Day 56, although only one death occurred due to the viremia/viral disease. Remarkably, all 3 cases who developed exogenous viremia/viral diseases including respiratory syncytial virus pneumonia/bronchitis and human parvovirus B19 viremia achieved a complete response, suggesting that high-dose polyclonal IVIG may be more effective against exogenous viruses rather than endogenous ones. Congestive heart failure was observed in 1 patient. High-dose polyclonal IVIG could be an effective and feasible therapy for refractory viremia/viral disease after allo-HCT.

Myocarditis is well known to be caused by viral infections such as Coxsackie virus group B, human herpes virus 6 and parvovirus B19. However, during the current emerging outbreak of SARS-CoV-2, there have been few case reports describing myocarditis as a possible presentation. In our case report we describe, early cardiac manifestations of SARS-CoV-2 in a UK District General Hospital. A 44-year-old Caucasian woman without any comorbidities presented with SARS-CoV-2 related fulminant myocarditis without initial respiratory symptoms. Patient underwent treatment with milrinone and methylprednisolone that showed reduction in myocardial inflammation and significantly improved myocardial contractility. This was then followed by a second phase of SARS-CoV-2 associated pneumonia and renal failure requiring ventilatory support and haemofiltration. Although, not described in the literature, we have found conjunctive use of milrinone and methylprednisolone effective in patient with SARS-CoV-2 fulminant myocarditis.
