Vaccine immunoprotection for Streptococcus pneumoniae is mediated by opsonizing antibodies targeting serotype-specific capsular polysaccharides. Quantitative antibody levels (ELISA) and antibody-mediated opsonophagcytic assays (OPA) measure vaccine-induced protection; correlation of these assays in transplantation requires investigation. This study examines the laboratory assessment of antibody titers in vaccinated renal recipients. Streptococcus pneumoniae 19A is common in immunocompromised hosts and is represented in protein-conjugate vaccines (PCV) and polysaccharide vaccines (PSV)...

Strongyloides stercoralis is a nematode causing serious infections in immunocompromised patients. In chronically infected patients, the low parasitic content as well as the resemblance of the larvae to several other species make diagnosis basedonmorphology difficult. In the present study, a PCR-based method targeting the internal transcribed sequence 2 (ITS2) of the rDNA region was examined for the molecular detection of S. stercoralis infection from the stool samples. A total of 1800 patients were included...

Pseudomonas infections are common among hospitalized, immunocompromised, and chronic lung disease patients. These infections are recalcitrant to common antibacterial therapies due to inherent antibiotic resistance. To meet the need of new anti- Pseudomonas drugs, a sensitive, homogenous, and robust assay was developed with the aim of identifying inhibitors of acyl-coenzyme A synthetases (ACSs) from Pseudomonas. Given the importance of fatty acids for in vivo nutrition of Pseudomonas, such inhibitors might have the potential to reduce the bacterial fitness during infection...

OBJECTIVES: PJP is a major cause of morbidity and mortality in immunocompromised individuals. Diagnosing PJP is often difficult because respiratory signs might be minimal or absent and the sensitivity of a chest X-ray (CXR) is low. We studied the clinical risk factors in order to increase awareness and facilitate the diagnosis. METHODS: We studied a prospective case series over a one year period (from 1 January 2015 to 1 January 2016) and did a retrospective analysis (from 2013 to 2016) of all PJP positive bronchoalveolar lavage (BAL) analysis...

AIMS: Human cytomegalovirus remains a significant issue for immunocompromised patients and existing viral polymerase targeting therapies are associated with significant toxicity. Accordingly, the viral terminase complex inhibitor, letermovir, is in development. We assessed letermovir pharmacokinetics in renal impairment. METHODS: This was a Phase 1, open-label, non-randomised trial. Estimated glomerular filtration rate (eGFR) based on the Modification of Diet Renal Disease equation was used to create 3 groups of 8 subjects: healthy function (eGFR ≥90 mL/min/1...

Adoptive cell therapy holds much promise in the treatment of cancer but results in solid tumors have been modest. The notable exception is tumor-infiltrating lymphocyte (TIL) therapy of melanoma, but this approach only works with high-dose preconditioning chemotherapy and systemic interleukin (IL)-2 postconditioning, both of which are associated with toxicities. To improve and broaden the applicability of adoptive cell transfer, we constructed oncolytic adenoviruses coding for human IL-2 (hIL2), tumor necrosis factor alpha (TNF-α), or both...

Acyclovir (ACV) and its derivatives have been highly effective for treating recurrent, lytic infections with Herpes Simplex Virus, type 1 (HSV-1), but searches for additional antiviral drugs are motivated by recent reports of resistance to ACV, particularly among immunocompromised patients. In addition, the relative neurotoxicity of ACV and its inability to prevent neurological sequelae among HSV-1 encephalitis survivors compel searches for new drugs to treat HSV-1 infections of the central nervous system (CNS)...

Despite advances in medical care, mortality due to cerebral Nocardia abscesses remains unacceptably high. In this report we present a typical immunocompromised patient, who deteriorated clinically despite optimal antimicrobial treatment. Adjuvant immunotherapy with IFN-γ resulted in partial restoration of the immune response, and paralleled clinical and radiographic recovery.

Sinusitis is a common disease. Complications, however, are less common and can be life threatening. Major complications occur from extension of disease into the orbit and intracranial compartment and often require emergent treatment with intravenous (IV) antibiotics or operative intervention. Immunocompromised patients with acute sinusitis are susceptible to atypical infections, such as invasive fungal sinusitis, which is a surgical emergency. Therefore, it is important to accurately and promptly identify potentional complications of acute sinusitis to ensure appropriate treatment and minimize negative outcomes...

Trichosporon asahii is an opportunistic yeastlike fungus commonly associated with systemic infections in immunocompromised patients. Neutropenia is recognized as the main risk factor in infections by T. asahii; however, little is known about the cytokine response during trichosporonosis. Here, we evaluated systemic and local cytokine production and histological damage in immunocompetent mice during systemic infection with T. asahii. We found a significant increased presence of G-CSF, TNF-α, IFN-γ, and IL-6 in sera samples...

The genus Raoultella has been separated from the genus Klebsiella in 2001. Two main species are responsible for human infections: R. ornithinolytica and R. planticola. The most frequent infections due to R. planticola include cystitis, pneumonia and bacteremia (mostly in immunocompromised hosts). To date, no joint or bone infection has been reported. We describe the first case of septic arthritis due to R. planticola following an arthroscopy with intra-articular injection of corticosteroids. Evolution was favorable after arthroscopic lavage and antibiotic therapy with quinolones...

Toxoplasma gondii has been suggested as an important opportunistic pathogen in immunocompromised patients. We conducted a global meta-analysis to assess the prevalence and odds ratios (ORs) of T. gondii infection in immunocompromised individuals. Electronic databases were reviewed for T. gondii infection in HIV/AIDS patients, cancer patients, and transplant recipients, and meta-analyses were conducted to calculate overall estimated prevalence and ORs using random or fixed-effects models. Totally, 72 eligible studies were included...

Elizabethkingia anophelis, originally discovered from Anopheles mosquito gut, is an emerging pathogen, especially in immunocompromised patients. We isolated two strains of E. anophelis from two separate patients with multiple organ dysfunction syndrome and lower respiratory tract infection. In this paper, we reviewed the status of E. anophelis infection and its antibiotics resistance from reported cases.

Neutrophils are the most abundant leukocytes in human circulation. They are the first immune cell population recruited to the sites of infection. However, the role of neutrophils to regulate host immune responses during respiratory viral infections is largely unknown. To elucidate the role of neutrophils in respiratory antiviral defense, we used an experimental mouse model of human metapneumovirus (HMPV) infection. HMPV, a member of the Paramyxoviridae family, is a leading respiratory pathogen causing severe symptoms, such as bronchiolitis and pneumonia, in young, elderly, and immunocompromised patients...

Varicella zoster virus (VZV) is a ubiquitous, human alphaherpesvirus that produces varicella on primary infection then becomes latent in ganglionic neurons along the entire neuraxis. In elderly and immunocompromised individuals, VZV reactivates and travels along nerve fibers peripherally resulting in zoster. However, VZV can also spread centrally and infect cerebral and extracranial arteries (VZV vasculopathy) to produce transient ischemic attacks, stroke, aneurysm, sinus thrombosis and giant cell arteritis, as well as granulomatous aortitis...

BACKGROUND: Periprosthetic joint infections are mainly caused by Gram-positive cocci. Leuconostoc mesenteroides is a rare microorganism mainly causing bloodstream infections. At times, it might be confused with another type of cocci and give rise to misdiagnosed infections. Molecular diagnosis and biofilm production comprise important techniques to guide antibiotic treatment.

The majority of tuberculosis (TB) cases in the United States are attributable to reactivation of latent TB infection (LTBI) (1). LTBI refers to the condition when a person is infected with Mycobacterium tuberculosis without signs and symptoms, or radiographic or bacteriologic evidence of TB disease. CDC and the U.S. Preventive Services Task Force (USPSTF) recommend screening populations at increased risk for LTBI, including persons who have lived in congregate settings at high risk and persons who were born in, or are former residents of countries with TB incidence ≥20 cases per 100,000 population (2-4)...

Mycobacterium fortuitum is a rapidly growing Mycobacterium species that is a rare cause of disease, primarily in immunocompromised patients. We present a preterm very low birth weight neonate who developed M. fortuitum bloodstream infection, where 16S rDNA sequencing allowed accurate identification. Cure was achieved by line removal and adjuvant combination treatment with amikacin, ciprofloxacin and clarithromycin.

INTRODUCTION: Gastrointestinal complications are common after renal transplantation, including oral lesions, esophagitis, gastritis, diarrhea, and colon carcinoma. The differential diagnosis is difficult in this scenario because multiple factors such as drugs, infections, and preexisting gastrointestinal disease come into play. CASE PRESENTATION: We report a case of varicella zoster virus-induced pancreatitis and hepatitis in a renal transplant recipient. The patient underwent renal transplantation 3 years earlier and now presented with severe pain in the epigastrium radiating to his back and had raised serum lipase levels and skin lesions characteristic of varicella...
