Methods: A randomized controlled, open label trial in patients with confirmed early syphilis who were randomized to treatment with cefixime 400 mg orally twice a day for 14 consecutive days or to a single dose of benzathine penicillin G (BPG) 2.

Efficacy, Safety, and Drug Survival During the First Year of Biologic Therapy for Psoriasis in Elderly Versus Younger Patients.

Background: Older people represent an increasing proportion of patients treated with biologics for psoriasis. However, data availability is limited due to the underrepresentation of older patients in clinical trials.

Materials And Methods: This is a multicentric real-world observational study conducted in dermatology centers in the Czech Republic.

PCR-detection rates of T. pallidum ssp. pallidum in swab samples from the Czech Republic (2004-2022): Combined RPR, IgM, and PCR tests efficiently detect active syphilis.

Syphilis is a multistage sexually transmitted disease caused by Treponema pallidum ssp. pallidum (TPA). This study analyzed clinical samples collected from patients with a diagnosed syphilis infection from 2004-2022, isolated in the Czech Republic.

Real-world efficacy and safety of dupilumab in children with atopic dermatitis under 6 years of age: a retrospective multicentric study.

In this multicentric real-world observational retrospective study, we evaluated the efficacy and safety of dupilumab for atopic dermatitis in children <6 years of age who underwent a minimum of 16 weeks of therapy. The analysis focused on EASI (Eczema Area and Severity Index), CDLQI (Children's Dermatology Life Quality Index), and Itch NRS (Numeric Rating Scale) changes from baseline to 4, 16, 24, 48, 72, and 96 weeks of follow-up (when available). Overall 24 children were included, with a mean age of 4.

Majority of Treponema pallidum ssp. pallidum MLST allelic profiles in the Czech Republic (2004-2022) belong to two SS14-like clusters.

Syphilis is a multistage sexually transmitted disease caused by Treponema pallidum ssp. pallidum. In the Czech Republic, there are around 700-800 new syphilis cases annually, continuously increasing since 2012.

Single-dose cefixime 800 mg plus doxycycline 100 mg twice a day for 7 days compared with single-dose ceftriaxone 1 g plus single-dose azithromycin 2 g for treatment of urogenital, rectal, and pharyngeal gonorrhoea: a randomised clinical trial.

Objectives: To evaluate the efficacy and tolerability of a single dose of oral cefixime 800 mg plus oral doxycycline 100 mg twice a day for 7 days, compared with a recommended single dose of ceftriaxone plus single dose of oral azithromycin, for treatment of uncomplicated urogenital, rectal, or pharyngeal gonorrhoea.

Methods: A noninferiority, open-label, multicentre randomized controlled trial was conducted in Prague, Czech Republic. Some 161 patients, 18-65 years of age diagnosed with uncomplicated urogenital, rectal, or pharyngeal gonorrhoea by nucleic acid amplification test (NAAT) were randomized to treatment with single dose of cefixime 800 mg plus doxycycline 100 mg twice a day for 1 week or a single dose of ceftriaxone 1 g intramuscularly plus single dose of azithromycin 2 g.

Serum TGF-1 and CD14 Predicts Response to Anti-TNF- Therapy in IBD.

Background: Tumor necrosis factor-alpha (TNF-) agonists revolutionized therapeutic algorithms in inflammatory bowel disease (IBD) management. However, approximately every third IBD patient does not respond to this therapy in the long term, which delays efficient control of the intestinal inflammation.

Methods: We analyzed the power of serum biomarkers to predict the failure of anti-TNF-.

Methylation analysis as an auxiliary tool in cytological diagnostics of infrequent anogenital lesions - a pilot study.

Methylation silencing of certain cellular genes is a sign of carcinogenesis progression and therefore tests that detect methylation could be used in the diagnosis or staging of malignant diseases. In the diagnosis of squamous cell carcinomas of the cervix which are almost 100% caused by long-term infection with highrisk human papillomavirus (HR-HPV), methylation silencing of certain cellular genes is a highly specific marker of advanced dysplastic lesions and appears to result from aberrant activation of the methyltransferase DNMT1 by viral oncoproteins E6 and E7. A methylation test performed on a cervicovaginal cytology specimen allows to increase the diagnostic value of this non-invasive test and to select patients with severe squamous cell lesions for follow-up.

Paradoxical Reactions to Anti-TNFα and Anti-IL-17 Treatment in Psoriasis Patients: Are Skin and/or Gut Microbiota Involved?

Psoriasis is a chronic, immune-mediated, inflammatory disease primarily affecting the skin. It is currently coming to light that patients with psoriasis have disrupted intestinal barrier and often suffer from comorbidities associated with the gastrointestinal tract. Moreover, there is growing evidence of both cutaneous and intestinal paradoxical reactions during biologic treatment in patients with psoriasis.

Skin microbiota signature distinguishes IBD patients and reflects skin adverse events during anti-TNF therapy.

Crohn's disease (CD) and ulcerative colitis (UC) are two forms of inflammatory bowel disease (IBD), where the role of gut but not skin dysbiosis is well recognized. Inhibitors of TNF have been successful in IBD treatment, but up to a quarter of patients suffer from unpredictable skin adverse events (SkAE). For this purpose, we analyzed temporal dynamics of skin microbiota and serum markers of inflammation and epithelial barrier integrity during anti-TNF therapy and SkAE manifestation in IBD patients.

Association between ustekinumab therapy and changes in specific anti-microbial response, serum biomarkers, and microbiota composition in patients with IBD: A pilot study.

Background: Ustekinumab, is a new therapy for patients with IBD, especially for patients suffering from Crohn's disease (CD) who did not respond to anti-TNF treatment. To shed light on the longitudinal effect of ustekinumab on the immune system, we investigated the effect on skin and gut microbiota composition, specific immune response to commensals, and various serum biomarkers.

Methodology/principal Findings: We recruited 11 patients with IBD who were monitored over 40 weeks of ustekinumab therapy and 39 healthy controls (HC).

Prevalence of genital and oral human papillomavirus infection among psoriasis patients on biologic therapy.

Current knowledge about human papillomavirus (HPV) infection in psoriasis patients treated with biologics is limited. In this study we evaluated the prevalence of oral and genital HPV infection in psoriasis patients treated with biologics or topical therapy for at least 6 months. The presence of HPV DNA in oral rinse and genital smears was evaluated.

Invasive Aspergillus infection of middle ear in a patient treated with secukinumab, methotrexate, and corticosteroids for psoriasis and psoriatic arthritis.

Mucocutaneous mycotic infections are common complications in patients on IL-17 inhibitor therapy. We report a case of a 33-year-old male with severe psoriasis and psoriatic arthritis on secukinumab combined with methotrexate and prednisone with swelling, otorrhea, and pain of the right ear and external auditory canal. Due to progressive hypacusis, a surgical solution was chosen.

Fecal Microbiome Changes and Specific Anti-Bacterial Response in Patients with IBD during Anti-TNF Therapy.

Inflammatory bowel diseases (IBD) are chronic disorders of the gastrointestinal tract that have been linked to microbiome dysbiosis and immune system dysregulation. We investigated the longitudinal effect of anti-TNF therapy on gut microbiota composition and specific immune response to commensals in IBD patients. The study included 52 patients tracked over 38 weeks of therapy and 37 healthy controls (HC).

Prevalence of high-risk human papillomavirus DNA and mRNA and its association with abnormal anal cytology in the Czech male anal cancer screening cohort.

Background: Anal cancer (AC) screening is justified in high-risk populations, particularly HIV-positive men having sex with men (MSM). HR-HPV testing could improve the efficiency of cytologically based screening of AC, as in the screening of biologically analogical cervical cancer. The specificity of HR-HPV testing is influenced by the prevalence of HR-HPV infection in the screened population.

Ongoing evolution of lymphogranuloma venereum: exploring the genomic diversity of circulating strains.

Lymphogranuloma venereum (LGV), the invasive infection of the sexually transmissible infection (STI) , is caused by strains from the LGV biovar, most commonly represented by -genotypes L2b and L2. We investigated the diversity in LGV samples across an international collection over seven years using typing and genome sequencing. LGV-positive samples (=321) from eight countries collected between 2011 and 2017 (Spain =97, Netherlands =67, Switzerland =64, Australia =53, Sweden =37, Hungary =31, Czechia =30, Slovenia =10) were genotyped for and variants.

A retrospective study on nested PCR detection of syphilis treponemes in clinical samples: PCR detection contributes to the diagnosis of syphilis in patients with seronegative and serodiscrepant results.

Syphilis, caused by Treponema pallidum ssp. pallidum (TPA), is a persisting global health problem. Although syphilis diagnostics relies mainly on serology, serological tests have some limitations, and it is recommended that the final diagnosis be supported by additional tests.
