Introduction: Toll-like receptor 7 (TLR7) is an important molecule involved in the development of autoimmunity and the response to different pathogens. Several polymorphisms within the gene were previously found to be associated with systemic lupus erythematosus (SLE). However, none of those studies investigated the promoter flanking variants rs1634318 and rs1616583. gene diversity has not been analyzed with respect to discoid lupus erythematosus (DLE) development, while its role in the human immunological response to fungal infection is not fully known.
Aim: To clarify the potential involvement of two novel single-nucleotide polymorphisms (SNPs) located in the gene (rs1634318 and rs1616583) in a variety of immune-related conditions, we studied the variability of these loci in patients from a Polish population with SLE and DLE, as well as in immunocompromised patients who were affected by invasive aspergillosis (IA) and those who were not affected.
Material And Methods: Real-time polymerase chain reaction was used to genotype SNPs. Statistically significant differences between case and control groups for both allele and genotype frequencies were assessed using the χ test with Yates' correction or two-tailed Fisher's exact test. The results were Bonferroni-corrected for multiple comparisons and odds ratios were calculated.
Results: Two polymorphisms located in might be associated with the development of SLE but not DLE within the Polish population. Moreover, variation of the two investigated SNPs was found to be associated with IA in immunocompromised Polish patients.
Conclusions: In Polish patients, promoter flanking gene polymorphisms might be associated with IA and SLE but not DLE.

To investigate if progression of coronary artery calcification (CAC) in patients with systemic lupus erythematosus (SLE) is associated with renal and traditional cardiovascular risk factors as well as incidence of myocardial infarctions. CAC progression was evaluated by cardiac computed tomography (CT) at baseline and after 5 years. Multivariable Poisson regression was applied to investigate associations between CAC progression and baseline values for traditional cardiovascular risk factors, CAC, SLE disease duration, lupus nephritis, and renal function.

Objective: The purpose of this review was to examine new evidence since our 2019 guidelines for cervical cancer (CC) screening in non-HIV immunocompromised persons and to provide updated recommendations based on literature review and expert opinion. In addition, human papillomavirus (HPV) vaccine efficacy in these populations was reviewed.
Methods: A literature search was performed similar to our previous publication but was conducted through March 2023.
Phototoxic reaction to oral terbinafine due to Tinea capitis in a child.

We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).

Papulonodular mucinosis is a rare dermatological condition characterized by mucin deposition in the dermis, leading to the formation of papules and nodules that can occur with, or antedate, autoimmune connective tissue diseases. This case report presents a 67-year-old female with a chronic history of cutaneous mucinosis, which posed significant diagnostic challenges. Despite various treatments and extensive diagnostic workup, her condition evolved, highlighting the difficulties in diagnosing papulonodular mucinosis, especially in the absence of systemic lupus erythematosus and antinuclear antibody positivity.

Acute coronary syndrome is the leading cause of death worldwide, with the highest rates occurring in low-income global regions. This is possibly due to increasing levels of urbanization, which are accompanied by changes in diet and lifestyle, the most common risk factors for coronary artery disease (CAD). Risk factors for CAD are divided into traditional and non-traditional risk factors.
