Background: Vitamin D is a fundamental regulator of host defenses by activating genes related to innate and adaptive immunity. In this study, we analyzed the association among single nucleotide polymorphisms (SNPs) in the () gene, with clinical patterns of AIDS progression in antiretroviral treatment (ART)-naïve HIV-infected patients.
Methods: We conducted a retrospective study in 667 HIV-infected patients, who were classified within three groups according to their AIDS progression pattern (183 long-term non-progressors (LTNPs), 334 moderate progressors (MPs), and 150 rapid progressors (RPs)). Five SNPs (rs11568820, rs4516035, rs2228570, rs1544410, and rs7975232) were genotyped using Agena Bioscience's MassARRAY platform.
Results: Significant association results were found for rs2228570. Within all HIV patients, the presence of T allele at rs2228570 SNP was protective against AIDS progression (ordinal outcome) under additive (adjusted odds ratio (aOR) = 0.75; = 0.009), dominant (aOR = 0.69; = 0.015), and codominant (aOR = 0.56; = 0.017) inheritance models. In addition, the same allele was protective under additive and codominant inheritance models when we compared with LTNPs vs. RPs [aOR = 0.64 ( = 0.019) and aOR = 0.37 ( = 0.018), respectively] and when we compared MPs vs. RPs [aOR = 0.72 ( = 0.035) and aOR = 0.45 ( = 0.028), respectively].
Conclusions: The rs2228570 T allele was related to a lower AIDS progression pattern in ART-naïve HIV-infected patients. These findings expand upon the knowledge about HIV pathogenesis in untreated HIV-infected patients with different clinical outcomes.

Article Synopsis
- The study focuses on enhancing early diagnosis of cryptococcal meningoencephalitis (CM) in HIV-negative patients to reduce mortality rates.
- Researchers conducted a retrospective analysis of patients with central nervous system infections, highlighting the importance of combining MRI findings with clinical symptoms for accurate diagnosis.
- Key findings showed that specific symptoms and MRI indicators, like the presence of pseudocysts, can significantly improve diagnosis accuracy, leading to better treatment outcomes for patients.
Correlation of Dental and Periodontal Status With HIV Presence and Initial CD4 Counts: An Albanian Prospective Observational Study.

Background Different pathologies are encountered more often in human immunodeficiency virus (HIV)-infected patients, such as bacterial, fungal, viral infection, and neoplastic diseases. Recently, studies have shown that HIV-infected individuals have poorer oral health outcomes, worse dentition, and aggressive forms of periodontitis. This study aims to investigate the dental and periodontal status of HIV-infected patients, the correlation between CD4+ level and the CD4 percentage with dentition, and periodontal status.

Highly active antiretroviral therapy has led to a significant increase in the life expectancy of people living with HIV. The trade-off is that HIV-infected patients often suffer from comorbidities that require additional treatment, increasing the risk of Drug-Drug Interactions (DDIs), the clinical relevance of which has often not been determined during registration trials of the drugs involved. Therefore, it is important to identify potential clinically relevant DDIs in order to establish the most appropriate therapeutic approaches.

Background: Antiretroviral drugs are essential for preventing mother-to-child transmission (MTCT) of HIV in HIV-infected pregnant women. However, ART treatment for HIV-infected pregnant women with multidrug resistance remains a major challenge. Effective and safe ART regimens for preventing MTCT should be tailored to this special population.

As life expectancy among patients infected with the human immunodeficiency virus (HIV) increases, a growing number of complications have been observed. This population displays an elevated risk of ischemic necrosis of the femoral head in comparison to the general population, which may be attributed to HIV infection, antiretroviral medication use, and hormone application. Patients infected with the human immunodeficiency virus (HIV) who also have necrosis of the femoral head tend to present at an earlier age, with a rapid disease progression and a high incidence of bilateral onset.
