Herpes simplex virus (HSV) is a human pathogen that infects epithelial cells. The cutaneous lesions, caused by the virus, spread to the nervous system creating several complications. Fusion of host membranes with the viral envelope is mandatory and mediated by a group of glycoproteins conserved in all Herpesviridae subfamilies, such as the glycoproteins B (gB), H (gH), L (gL) and D (gD). We investigated the inhibitory activity mediated by synthetic overlapping peptides spanning the entire ectodomains of gH and gL glycoproteins...

Herpes simplex virus (HSV) is the most common cause of non-epidemic, sporadic, acute focal encephalitis in the United States. Inflammation of the vasculature makes them friable and susceptible to hemorrhage. Massive hemorrhage, though rare, can present in a delayed fashion after initiation of acyclovir and often requires surgical intervention. We report a unique case of delayed temporal lobe hemorrhage after initiation of acyclovir in an immunocompetent patient, specifically for its presentation, virology, and surgical management...

Organic anion transporters (OATs) play an important role in the renal secretion of drugs, and their functional change can result in pharmacokinetic variability. In this study, we applied transport rates measured using OAT-transfected human embryonic kidney cells to predict human renal secretory and total renal clearance of 31 diverse drugs. Selective substrates to OAT1 (tenofovir), OAT2 (acyclovir and ganciclovir) and OAT3 (benzylpenicillin, oseltamivir acid) were used to obtain relative activity factors (RAFs) for these individual transporters by relating in vitro transport clearance to in vivo secretory clearance...

Multiple myeloma is characterised by the neoplastic proliferation of a single clone of plasma cells producing a monoclonal immunoglobulin. This clone of plasma cells proliferates in the bone marrow, resulting in extensive skeletal destruction with osteolytic lesions, osteopenia and pathological fractures. Additional disease-related complications include hypercalcaemia, renal insufficiency, anaemia and infection. We present the case of a 64-year-old woman presenting with rapid onset, painful distal symmetrical lower limb weakness and an acute kidney injury...

Infections of the central nervous system (CNS) with varicella zoster virus (VZV) is a rare occurrence after allogeneic hematopoietic stem cell transplantation. We herein report a case of VZV meningitis, radiculitis and myelitis that developed 8 months after cord blood transplantation, shortly after the cessation of cyclosporine and low-dose acyclovir. Although treatment with acyclovir did not achieve a satisfactory response, the patient was successfully treated with foscarnet. Our report indicates that VZV infection should be considered in allo-hematopoietic stem cell transplantation (HSCT) patients with CNS symptoms and that foscarnet may be effective for the treatment of acyclovir-resistant VZV infections of the CNS...

Ustekinumab, a monoclonal antibody that binds to the shared p40 subunit of interleukin (IL)-12 and IL-23, is approved in the USA and Europe for moderate to severe plaque psoriasis. There are concerns that biologic treatments like ustekinumab may lead to an increased rate of infections. We report a 77-year-old woman who developed varicella zoster virus meningitis 8 weeks after initiation of ustekinumab therapy because of plaque psoriasis. She presented clinically with sudden onset of fatigue, vertigo, nausea and epileptic seizures...

Dear Editor, Pityriasis rosea is a common, acute, and self-limiting dermatosis, which is associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and/or HHV-7 (1). It predominantly affects individuals of both sexes in their second or third decade of life and is clinically characterized by the occurrence of an initial erythematosquamous plaque followed by the appearance of disseminated similar but smaller lesions one or two weeks later. Several patients develop systemic symptoms such as nausea, anorexia, malaise, headache, fever, arthralgia, and lymphadenopathy that may precede or accompany the eruption; the latter follows the cleavage lines of the trunk creating the configuration of a Christmas tree and spontaneously resolves within 4 to 8 weeks...

Dear Editor, Erythema multiforme is considered an acute skin condition, characterized by a self-limiting and sometimes recurrent course. It is regarded as a type IV hypersensitivity reaction associated with certain infections, medications, and other various triggers. Allergic contact dermatitis is in turn a delayed type of induced allergy as a result of cutaneous contact with a specific allergen to which the patient develops specific sensitivity. This type of cutaneous reaction is associated with inflammation manifesting with erythema, edema, and vesicles...

Herpes simplex viruses (HSV) are common human pathogens that can cause painful but benign manifestations and recurrent complaints, but can also cause significant morbidity and mortality on infection of the eye or brain and with disseminated infection of an immunosuppressed patient or a neonate. HSV growth inhibition measurement by plaque or yield reduction is a key task in the development of novel antiviral compounds but the manual methods are very labour intensive. The sensitive and specific PCR technology could be an effective method for quantitation of HSV DNA related to virus replication; however the currently described PCR approaches have a major limitation, namely the requirement of purification of DNA from the infected cells...

The critical role of βTrCP1 in cancer development makes it a discerning target for the development of small drug like molecules. Currently, no inhibitor exists that is able to target its substrate binding site. Through molecular docking and dynamics simulation assays, we explored the comparative binding pattern of βTrCP1-WD40 domain with ACV and its phospho-derivatives (ACVMP, ACVDP and ACVTP). Consequently, through principal component analysis, βTrCP1-ACVTP was found to be more stable complex by obscuring a reduced conformational space than other systems...
