Babesiosis is an emerging tick-borne disease transmitted by the hard tick Ixodes scapularis, which also transmits Lyme disease. Better gradation of prognostic indicators are needed to determine which patients may develop serious complications requiring hospitalization, and to provide early guidance on appropriate therapy. In this study, we evaluated 128 patients with smear or real time polymerase chain reaction-confirmed Babesia microti infections over a period of 16 years. Patients with asplenia or immunocompromising conditions were more likely to have severe infection (P < 0...

BACKGROUND: Canine papillomaviruses can affect the mucous membranes and skin of young, old and immunocompromised dogs. Most lesions regress spontaneously over a four to eight week interval; however, in some cases the lesions may persist or progress. Cryotherapy is used as a treatment for papillomavirus induced lesions in veterinary practice but there is limited published evidence regarding its use. OBJECTIVES: To describe the history, lesions and treatment outcomes of three dogs with persistent viral papillomas treated with cryotherapy...

AIM: Human cytomegalovirus constitutes a prevalent and serious threat to immunocompromised individuals and requires new treatments. Letermovir is a novel viral-terminase inhibitor that has demonstrated prophylactic/preemptive activity against human cytomegalovirus in Phase 2 and 3 transplant trials. As unchanged letermovir is primarily excreted via the liver by bile, this trial aimed to assess the effect of hepatic impairment on letermovir pharmacokinetics. METHODS: Phase 1, open-label, parallel-group pharmacokinetic and safety comparison of multiple once-daily oral letermovir in female subjects with hepatic impairment and healthy matched controls...

Candida albicans is an opportunistic pathogen, typically found as a benign commensal yeast living on skin and mucosa, but poised to invade injured tissue to cause local infections. In debilitated and immunocompromised individuals, C. albicans may spread to cause life-threatening systemic infections. Upon contact with serum and at body temperature, C. albicans performs a regulated switch to filamentous morphology, characterized by emergence of a germ tube from the yeast cell followed by mold-like growth of branching hyphae...

Vaccinia-based systems have been extensively explored for the development of recombinant vaccines. Herein we describe an innovative vaccinia virus (VACV)-derived vaccine platform technology termed Sementis Copenhagen Vector (SCV), which was rendered multiplication-defective by targeted deletion of the essential viral assembly gene D13L. A SCV cell substrate line was developed for SCV vaccine production by engineering CHO cells to express D13 and the VACV host-range factor CP77, because CHO cells are routinely used for manufacture of biologics...

Talaromyces marneffei is a dimorphic fungus endemic mainly in southeast and south Asia. It causes severe mycosis, usually in immunocompromised individuals, such as those with human immunodeficiency virus (HIV) infection. Concomitant infection with T. marneffei and other opportunistic pathogens is plausible because the majority of T. marneffei infections occur in patients with advanced HIV infection. Nonetheless, coinfection in the same site has rarely been reported, and poses a considerable diagnostic and therapeutic challenge...

AbstractToxoplasma gondii infects a broad range of warm-blooded hosts, including humans. Important clinical manifestations include encephalitis in immunocompromised patients as well as miscarriage and fetal damage during early pregnancy. Toxoplasma gondii dense granule antigen 2 and 5 (GRA2 and GRA5) are essential for parasitophorous vacuole development of the parasite. To evaluate the potential of GRA2 and GRA5 as recombinant DNA vaccine candidates, these antigens were cloned into eukaryotic expression vector (pcDNA 3...

New regulations concerning EHEC/VTEC Hemolytic Uremic Syndrome (HUS) is the most severe complication to an infection with EHEC (enterohemorrhagic E. coli), also called VTEC (verocytotoxin-producing E. coli). Risk of severe complications such as HUS is an important reason why the Swedish Communicable Diseases Act (Smittskyddslag. 2004:168) includes infection with EHEC. With very few exceptions, only EHEC with the stx2 gene is associated with HUS. According to the law, persons working with unpackaged foods, infants or severely immunocompromised patients, and children attending preschool can be suspended awaiting negative test results for EHEC...

Small-molecule inhibitors offer great promise for targeting pathways that are specifically deregulated in different tumors. However, such 'targeted' therapies also elicit poorly understood effects on protective antitumor immunity. Given the emerging relevance of immunotherapies that boost pre-existing T cell responses, understanding how different immune cells are affected by small-molecule inhibitors could lead to more-effective interventions, alone or combined with immunotherapy. This review discusses the growing array of activities elicited by multiple 'targeted' inhibitors on antitumor immunity, underscoring the complex effects resulting from diverse activities on different immune cell types in vivo, and the need to conduct mechanistic research that identifies drugs performing well not only in immunocompromised mice but also in the presence of spontaneous or therapeutic antitumor immunity...

Cystitis cystica or glandularis is a clinical and pathological entity of the bladder mucosa occurring secondary to inflammation or chronic obstruction. Its premalignant nature remains controversial, especially in an immunocompromised transplant recipient. We present a rare case where a chronic kidney disease patient was found to have cystitis glandularis while being worked up for living-related donor renal transplant and describe its subsequent management.
