Fatal Multiorgan Failure Syndrome in a Strongyloides-HTLV-1 Coinfected Patient, after Treatment with Ivermectin

Because of its characteristic features of autoinfection, the parasitic nematode Strongyloides stercoralis can infect patients for years. An acceleration of its autoinfective cycle can be triggered by human T-lymphotropic virus-1 (HTLV-1) infection, mainly by the deviation of the protective Th2- to Th1-type immune response and can lead to severe disease by dissemination of Strongyloides stercoralis larvae carrying intestinal bacteria to multiple organs. Meningitis caused by enteric Gram-negative bacteria is a potentially fatal complication of disseminated strongyloidiasis. Herein, we present the case of a Strongyloides-HTLV-1 coinfected patient, admitted for E. coli meningitis. One day after initiation of ivermectin, the patient developed significant S. stercoralis dissemination, complicated by multiorgan failure syndrome, and died from neurological failure. While the initial clinical scenario of our case has already been well described in the literature, its course after antihelminthic treatment initiation remains unclear and needs to be discussed.

Coinfection in SARS-CoV-2 Infected Children Patients

Introduction: The aim of this study is to determine the coinfections with other respiratory pathogens in SARS-CoV-2 infected children patients in a pediatric unit in Istanbul. Methodology: This retrospective descriptive study was conducted in a 1000-bedded tertiary education and research hospital in Istanbul. All children hospitalized with the diagnosis of SARS-CoV-2 infection had been investigated for respiratory agents in nasopharyngeal secretions. Laboratory confirmation of SARS-CoV-2 and the other respiratory pathogens were performed using reverse transcriptase-polymerase chain reaction (RT-PCR). Results: A total of 209 hospitalized children with suspected SARS-CoV-2 infection between March 2020-May 2020 were enrolled in this study. Among 209 children, 93 (44.5%) were RT-PCR positive for SARS-CoV-2 infection, and 116 (55.5%) were RT-PCR negative. The most common clinical symptoms in all children with SARS-CoV-2 infection were fever (68.8%) and cough (57.0%). The other clinical symptoms in decreasing rates were headache (10.8%), myalgia (5.4%), sore throat (3.2%), shortness of breath (3.2%), diarrhea (2.2%) and abdominal pain in one child. In 7 (7.5%) patients with SARS-CoV-2 infection, coinfection was detected. Two were with rhinovirus/enterovirus, two were with Coronavirus NL63, one was with adenovirus, and one was with Mycoplasma pneumoniae. In one patient, two additional respiratory agents (rhinovirus/enterovirus and adenovirus) were detected. There was a significantly longer hospital stay in patients with coinfection (p = 0.028). Conclusions: Although the coinfection rate was low in SARS-CoV-2 infected patients in our study, we found coinfection as a risk factor for length of hospital stay in the coinfected patient group.

INVESTIGATION OF A POSSIBLE ASSOCIATION BETWEEN KIF1A GENE AND MICROCEPHALY IN ZIKA-DENGUE COINFECTED PATIENT

People living in Columbia & brazil are experiencing ZIKA-DENGUE coinfection from last few years. After infecting some patients are asymptomatic, few of them are showing mild symptoms & some of them are experiencing serious neurological issues. The situation become more challenging if any pregnant woman coinfected by DENGUE-ZIKA at the same time, the neonatal may develop microcephaly (A neurological developmental disorder). The reason behind this is not clear yet & no such treatment is established to treat the neuronal complications. It is established that microcephaly is a genetic disease & KIF1A gene is responsible for this. I would like to investigate about this particular phenomenon and will try to give a new concept, which can be used for future treatment.

A Case of Severe Acute Respiratory Syndrome Coronavirus 2 Treatment With Remdesivir in a Hepatitis C-Coinfected Patient Resulting in Temporary Viral Control and Posttreatment Flare

We report a case of a man with chronic hepatitis C infection treated with remdesivir for COVID-19, resulting in lowered HCV viral load, followed by a rebound after its discontinuation. Concomitant treatment with tocilizumab possibly caused loss of anti-HBs.

Six Cases of Zika/Dengue Coinfection in a Brazilian Cohort, 2015–2019

Brazil is one of the countries which has been most affected by dengue epidemics. This scenario became more challenging with the emergence of Zika virus after 2014. The cocirculation of dengue and Zika viruses makes their diagnosis and treatment a challenge for health professionals, especially due to their similar clinical outcomes. From 2015 to 2019, we followed a cohort of 2017 participants in Goiania, Goias, Central Brazil. Febrile cases were monitored weekly, and after identification of fever, the physician performed a home visit for clinical evaluation and collection of blood/urine for diagnosis of acute dengue/Zika infection in suspected cases. Dengue acute infection was investigated by NS1 antigen and real time RT-PCR and seroconversion of anti-dengue IgM. ZIKV infection was confirmed by real time RT-PCR. Six cases of Zika/dengue coinfection among participants were reported. The clinical outcomes were suggestive for both DENV and ZIKV infection. No coinfected patient had neurological clinical manifestation, warning signs or need for hospitalization. A continuous specific laboratory confirmation for both dengue and Zika viruses should be enforced as part of the surveillance systems even in the presence of very suggestive cases of dengue fever, minimizing the risk of a late detection of ZIKV circulation.

HBV Infection in HIV-Driven Immune Suppression

Worldwide, approximately 10% of all human immunodeficiency virus (HIV)-infected people are also chronically coinfected with hepatitis B virus (HBV). HBV infection has a poor prognosis in HIV-positive people and has been documented by an increased risk of developing chronic HBV infection (CHB), progression to liver fibrosis and end-stage liver disease (ESLD) and evolution of hepatocellular carcinoma (HCC). Furthermore, in HIV patients, HBV-resolved infection is often associated with the appearance of HBV-DNA, which configures occult HBV infection (OBI) as a condition to be explored in coinfected patients. In this narrative review we summarize the main aspects of HBV infection in HIV-positive patients, emphasizing the importance of carefully considering the coinfected patient in the context of therapeutic strategies of antiretroviral therapy.

Cure of chronic hepatitis C virus infection in an HIV-coinfected patient with multiple comorbidities and drug interaction challenges

Curing hepatitis C virus (HCV) infection in patients harbouring multiple severe comorbidities is a medical challenge. Evidence-based data are lacking regarding HCV treatment with direct-acting antiviral regimens in particular populations of HCV/HIV-coinfected patients with cirrhosis and chronic kidney disease on haemodialysis. Here, we present the HCV treatment challenges facing a patient with HIV coinfection, prior failure of both HIV-1 and HCV therapy, cirrhosis, end-stage renal failure on haemodialysis, as well as management of drug–drug interactions, especially given the need to receive long-term amiodarone therapy.
