Атипичные презентации Acolovir-Resistant Herpes Simplex Virus в иммунокомпромиссированных пациентах: Серия дел.

Инфекции, связанные с вирусом герпеса (HSV), у иммунокомпромиссированных пациентов могут иметь атипичные представления - от грануломатных до линейных эрозийных повреждений - и превращаться в рефракторную и стандартную терапию. Мы сообщаем three :: случаи некротизации категорической инфекции HSV у иммунокомпромиссированных пациентов с гематологическими малигнациями или предшествующими химиотерапиями, все из которых имеют нетипичные и рефракторные проявления заболевания. One дело касалось 53-year-old :: пациентка с реанимацией/рефрактом острой миэлоидной лейкемией (АМЛ), разработавшая некротизир

Orf Virus ORF120 Protein Positively Regulates the NF-κB Pathway by Interacting with G3BP1.

Orf virus (ORFV) is a highly epitheliotropic parapoxvirus with zoonotic significance that induces proliferative lesions in the skin of sheep, goats, and humans. Several viral proteins carried by ORFV, including nuclear factor-κB (NF-κB) inhibitors, play important roles in hijacking host-associated proteins for viral evasion of the host innate immune response. However, the roles of proteins with unknown functions in viral replication and latent infection remain to be explored. Here, we present data demonstrating that the ORF120, an early-late ORFV-encoded protein, activates the NF-κB pathway in

Pseudomonas aeruginosa Infections in Cancer Patients.

Pseudomonas aeruginosa (P. aeruginosa) is one of the most frequent opportunistic microorganisms causing infections in oncological patients, especially those with neutropenia. Through its ability to adapt to difficult environmental conditions and high intrinsic resistance to antibiotics, it successfully adapts and survives in the hospital environment, causing sporadic infections and outbreaks. It produces a variety of virulence factors that damage host cells, evade host immune responses, and permit colonization and infections of hospitalized patients, who usually develop blood stream, respirato

Real-Life Use of Ceftolozane/Tazobactam for the Treatment of Bloodstream Infection Due to Pseudomonas aeruginosa in Neutropenic Hematologic Patients: a Matched Control Study (ZENITH Study).

We sought to assess the characteristics and outcomes of neutropenic hematologic patients with Pseudomonas aeruginosa (PA) bloodstream infection (BSI) treated with ceftolozane-tazobactam (C/T). We conducted a multicenter, international, matched-cohort study of PA BSI episodes in neutropenic hematologic patients who received C/T. Controls were patients with PA BSI treated with other antibiotics. Risk factors for overall 7-day and 30-day case fatality rates were analyzed. We compared 44 cases with 88 controls. Overall, 91% of episodes were caused by multidrug-resistant (MDR) strains. An endogenou

Pyoderma gangrenosum: pathogenetic mechanisms and their implications for treatment.

Pyoderma gangrenosum (PG) is a rare inflammatory skin disease belonging to the group of neutrophilic dermatoses. The pathogenesis of PG involves a predisposing genetic background that facilitates a dysregulated innate and adaptive immune response, with an imbalance between pro-inflammatory and anti-inflammatory mediators, leading to neutrophil-driven inflammatory damage. Several immunosuppressants and immunomodulatory drugs are currently available for the treatment of PG, in combination with topical therapies, wound management and pain control strategies. Systemic corticosteroids and cyclospor

Skin manifestations associated with systemic diseases - Part II.

The skin, by reflecting internal processes, externalizes what happens inside the body in many diseases. Thus, the skin, as an organ, extrapolates its functions of protection, barrier and signals the existence of systemic diseases, expanding the importance of the dermatologist beyond the skin surface. Thus, the dermatologist investigates diagnostic hypotheses for conditions related to all systems and refers patients to the appropriate specialty. Combined with examination by a trained eye, the skin, due to its easy access, is still the ideal place for performing biopsies, which often clarify the
