Abstract
BACKGROUND During the 2015 Zika virus infection (ZVI) epidemic swiping through the Americas, few cases of ZVI with severe, potentially life-threatening thrombocytopenia were reported. Platelet transfusion, corticosteroids and intravenous immunoglobulins (IVIG) were in most cases applied as therapeutic options, predominantly with success. We present a comprehensive overview concerning the pathophysiology, treatment strategies and outcomes of patients with ZVI and severe thrombocytopenia (platelet count <50 × 109/L). METHOD A literature search was performed. RESULTS Eleven case reports and case series with a total of 28 patients met the inclusion criteria; including five cases with lethal outcome. Therapeutic strategies, including platelet transfusion, administration of steroids and/or IVIG were described in 24 cases. CONCLUSIONS Severe thrombocytopenia is a rare, but potentially life-threatening complication of ZVI. The principal pathophysiological mechanism appears to immune-induced thrombocytopenia. Due to a paucity of cases, the optimal treatment strategy remains to be elucidated.

Epidemiology and Viral Etiology of Pediatric Immune Thrombocytopenia through Korean Public Health Data Analysis. J Clin Med 2021; 10:jcm10071356. [PMID: 33806145 PMCID: PMC8037772 DOI: 10.3390/jcm10071356] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 03/19/2021] [Accepted: 03/22/2021] [Indexed: 12/16/2022] Open
Abstract
Immune thrombocytopenic purpura (ITP) is prevalent in children aged 2-5 years but may occur in all pediatric age groups. In 50-60% of pediatric patients, ITP is preceded by an upper respiratory tract infection 1-4 weeks before its onset. In this study, the relationship between the development of ITP and viral infections in children was assessed. We analyzed data of 6487 patients aged < 18 years with incident ITP from the Health Insurance Review and Assessment Open Access Big Data Platform (2015 to 2018) and the Korea Disease Control and Prevention Agency. The monthly positive detection rate (PDR) of seven respiratory and four acute diarrhea viruses was calculated. The virus PDR seasonal trend data was analyzed through ARIMA modeling. The ITP diagnostic data and prevalence of viral infection 1 and 2 months prior were analyzed using the Granger test. The overall male to female (M/F) ratio was 1.2, whereas it was 1.4 in the youngest age group (< 1 year). The overall ITP incidence rate was 18.1 per 100,000 person-years. Respiratory syncytial virus, rhinovirus, rotavirus, and astrovirus infections influenced ITP occurrence in children. However, rotavirus infection is positively associated with the etiology of ITP after 1-2 months.

Abstract
Thrombocytopenia, which signifies a low platelet count usually below 150 × 109/L, is a common finding following or during many viral infections. In clinical medicine, mild thrombocytopenia, combined with lymphopenia in a patient with signs and symptoms of an infectious disease, raises the suspicion of a viral infection. This phenomenon is classically attributed to platelet consumption due to inflammation-induced coagulation, sequestration from the circulation by phagocytosis and hypersplenism, and impaired platelet production due to defective megakaryopoiesis or cytokine-induced myelosuppression. All these mechanisms, while plausible and supported by substantial evidence, regard platelets as passive bystanders during viral infection. However, platelets are increasingly recognized as active players in the (antiviral) immune response and have been shown to interact with cells of the innate and adaptive immune system as well as directly with viruses. These findings can be of interest both for understanding the pathogenesis of viral infectious diseases and predicting outcome. In this review, we will summarize and discuss the literature currently available on various mechanisms within the relationship between thrombocytopenia and virus infections.

Abstract
Introduction: Antinuclear antibody (ANA) tests are widely used for the diagnosis of autoimmune diseases, but ANAs are also commonly found in patients with various infections. This retrospective study aimed to investigate the relationship between infections and ANA status.Methods: Patients that visited the Department of Infectious Diseases at Inha University Hospital between January 2007 and July 2018 were investigated. We analysed their ANA test results and reviewed rheumatic and infectious diagnoses of patients with positive ANA findings.Results: Of the 9,320 patients during the study period, 1,111 underwent ANA testing and 110 tested positive. Seven of the 110 patients were previously diagnosed with ANA-positive disease, and 21 were diagnosed with autoimmune disease during the present study. Of the remaining 82 patients, 43 were confirmed with infectious disease. The most common pathogen was Mycobacterium tuberculosis (n = 10), followed by Treponema pallidum (n = 5), Orientia tsutsugamushi (n = 5), Escherichia coli (n = 5), Bartonella henselae (n = 3), and human immunodeficiency virus (n = 3). Of the 39 patients without a confirmed pathogen, 7 were seropositive for O. tsutsugamushi, B. henselae, or Rickettsia spp. Patients were observed at an average of 24 weeks in our hospital. One patient developed systemic lupus erythematosus after being diagnosed with Epstein-Barr virus-induced infectious mononucleosis, and another patient developed adult-onset Still's disease after being diagnosed with scrub typhus.Conclusion: This study showed that various relationships exist between infections and rheumatic diseases. In particular, several patients with a positive ANA test result were found to have intracellular infections such as mycobacterial infections, syphilis, or scrub typhus.

Abstract
Immune thrombocytopenic purpura (ITP) is an autoimmune disorder that causes isolated thrombocytopenia. Many viruses have been identified as triggering the autoimmune process, including HIV, MCV, EBV, parvovirus, rubella and measles. However, ITP in association with coronavirus infection has not previously been reported. We describe the case of a healthy man who presented with severe ITP complicated by intracranial haemorrhage following upper respiratory tract infection. An infection screen revealed coronavirus infection.

Abstract
PURPOSE OF REVIEW We review the range of dermatological signs seen in Zika infection and the possible relationship between the rash and viremia. We also hoped to explore the utility of mucocutaneous manifestations in narrowing the differential diagnosis from other similar flaviviruses. RECENT FINDINGS Clinical manifestations of Zika infection share many similarities with other mosquito-borne viruses such as dengue. These include non-specific symptoms such as a fever, rash, arthralgia, myalgia, and conjunctivitis. The morphology of the rash in Zika infection is not very specific and commonly described as maculopapular and centrifugal that usually extends to become diffuse. We reviewed 123 publications, encompassing a total of 368 Zika cases. One hundred seven cases with rash had sufficient data for detailed analysis. 8.4% of cases with rash had hemorrhagic manifestations such as palatal petechiae and bleeding ulcers. Only 20 reported cases were tested for viremia during presence of rash, and 70.6% of these cases were positive. While mucocutaneous complications are common in Zika infection, more research is necessary to determine the impact of rash on diagnosis, prognosis, and transmissibility in Zika infection.

Abstract
The Zika virus (ZIKV) global epidemic prompted the World Health Organization to declare it a 2016 Public Health Emergency of International Concern. The overwhelming experience over the past several years teaches us that ZIKV and the associated neurological complications represent a long-term world-wide challenge to public health. Although the number of ZIKV cases in the Western Hemisphere has dropped since 2016, the need for basic research and anti-ZIKV drug development remains strong. Re-emerging viruses like ZIKV are an ever-present threat in the 21st century where fast transcontinental travel lends itself to viral epidemics. Here, we first present the origin story for ZIKV and review the rapid progress researchers have made toward understanding of the ZIKV pathology and in the design, re-purposing, and testing–particularly in vivo–drug candidates for ZIKV prophylaxis and therapy ZIKV. Quite remarkably, a short, but intensive, drug-repurposing effort has already resulted in several readily available FDA-approved drugs that are capable of effectively combating the virus in infected adult mouse models and, most importantly, in both preventing maternal-fetal transmission and severe microcephaly in newborns in pregnant mouse models.

Abstract
Background Zika virus (ZIKV) infection has been associated with severe thrombocytopenia. We describe the incidence, clinical manifestations, and outcomes of patients with ZIKV infection and thrombocytopenia. Methods We reviewed medical records of patients with ZIKV infection and thrombocytopenia (platelet count <100 ×109 cells/L) in Puerto Rico during 2016. Severe thrombocytopenia was defined by platelet count <20 ×109/L or a platelet count <50 ×109/L and treatment for immune thrombocytopenia (ITP). Results Of 37 878 patients with ZIKV infection, 47 (0.1%) had thrombocytopenia in the absence of an alternative etiology (1.4 cases/100 000 population), including 12 with severe thrombocytopenia. Most patients with thrombocytopenia were adult (77%) and male (53%). Platelet nadir occurred a median (range) of 6 (1-16) and 5 (0-34) days after symptom onset for patients with severe and nonsevere thrombocytopenia, respectively. Among patients with severe thrombocytopenia, all had bleeding, 33% were admitted to the intensive care unit, and 8% died; 50% were treated for ITP. Among 5 patients with severe thrombocytopenia who received intravenous immunoglobulin, the median platelet count increase (range) was 112 (65-202) ×109/L. In contrast, among 4 patients who received platelet transfusion, the median increase in platelet count (range) was 8.5 (-6 to 52) ×109/L. Conclusions Patients with severe thrombocytopenia and ZIKV infection experienced prominent acute morbidity. Consistent with recommended management, administration of ITP treatments to such patients may be more efficacious than platelet transfusion in resolving thrombocytopenia. Severe thrombocytopenia should be considered a rare outcome of ZIKV infection.

Abstract
Background. The Zika virus (ZIKV) outbreak in the Americas has caused international concern due to neurological sequelae linked to the infection, such as microcephaly and Guillain-Barré syndrome (GBS). The World Health Organization stated that there is “sufficient evidence to conclude that Zika virus is a cause of congenital abnormalities and is a trigger of GBS”. This conclusion was based on a systematic review of the evidence published until 30.05.2016. Since then, the body of evidence has grown substantially, leading to this update of that systematic review with new evidence published from 30.05.2016 – 18.01.2017, update 1. Methods. We review evidence on the causal link between ZIKV infection and adverse congenital outcomes and the causal link between ZIKV infection and GBS or immune-mediated thrombocytopaenia purpura. We also describe the transition of the review into a living systematic review, a review that is continually updated. Results. Between 30.05.2016 and 18.01.2017, we identified 2413 publications, of which 101 publications were included. The evidence added in this update confirms the conclusion of a causal association between ZIKV and adverse congenital outcomes. New findings expand the evidence base in the dimensions of biological plausibility, strength of association, animal experiments and specificity. For GBS, the body of evidence has grown during the search period for update 1, but only for dimensions that were already populated in the previous version. There is still a limited understanding of the biological pathways that potentially cause the occurrence of autoimmune disease following ZIKV infection. Conclusions. This systematic review confirms previous conclusions that ZIKV is a cause of congenital abnormalities, including microcephaly, and is a trigger of GBS. The transition to living systematic review techniques and methodology provides a proof of concept for the use of these methods to synthesise evidence about an emerging pathogen such as ZIKV.

Abstract
PURPOSE OF REVIEW Zika virus (ZIKV), a mosquito-borne flavivirus, has gained recognition over the past few years as an important new cause of congenital infection. As a result, it is critical that pediatricians understand its epidemiology, clinical presentation, clinical sequelae, and management. RECENT FINDINGS The recent ZIKV epidemiology, clinical presentation of acute infection in children and complications, perinatal infection, and congenital infection will be summarized in this ZIKV review. This will be followed by a brief summary on ZIKV diagnosis, management, treatment, and prevention. SUMMARY The field of clinical research in ZIKV has rapidly evolved over recent months. It is critical that pediatricians continue to stay up-to-date with the continuously evolving understanding of the clinical aspects of ZIKV to ensure optimal identification and management of affected infants and children. Given the recent changes in Centers for Disease Control and Prevention guidelines to limit screening of asymptomatic pregnant women in the United States with possible ZIKV exposure, comprehensive ZIKV clinical knowledge becomes even more crucial.

Abstract
Severe thrombocytopenia during or after the course of Zika virus infection has been rarely reported. We report 7 cases of severe thrombocytopenia and hemorrhagic signs and symptoms in Guadeloupe after infection with this virus. Clinical course and laboratory findings strongly suggest a causal link between Zika virus infection and immune-mediated thrombocytopenia.

Abstract
Although Zika virus (ZIKV) was isolated approximately 70 years ago, few experimental studies had been published prior to 2016. The recent spread of ZIKV to countries in the Western Hemisphere is associated with reports of microcephaly, congenital malformations, and Guillain-Barré syndrome. This has resulted in ZIKV being declared a public health emergency and has greatly accelerated the pace of ZIKV research and discovery. Within a short time period, useful mouse and non-human primate disease models have been established, and pre-clinical evaluation of therapeutics and vaccines has begun. Unexpectedly, ZIKV exhibits a broad tropism and persistence in body tissues and fluids, which contributes to the clinical manifestations and epidemiology that have been observed during the current epidemic. In this Review, we highlight recent advances in our understanding of ZIKV pathogenesis, tissue tropism, and the resulting pathology and discuss areas for future investigation.
