New method of the diagnosis and cultivation of Chlamydia trachomatis using peripheral blood leukocyte cultures is worked out and implemented in the clinical practice. This method was used for the diagnosis of asymptomatic chlamydial infection in sportsmen. Among 48 sportsmen Chlamydia trachomatis was diagnosed in 28 persons. Morbidity in these sportsmen was significantly higher, than in sportsmen without chlamydial infection. Number of macrophage-lymphocyte rosettes in leukocyte cultures that reflects immune reactivity of organism was significantly low in sportsmen with Chlamydia trachomatis than in the group without this infection. Results of our studies showed that leukocyte culture method is the most useful and reliable for the detection of latent or asymptomatic Chlamydia trachomatis infection. The diagnosis of this infection in sportsmen helps to reveal the reason of different clinical symptoms to carry out the appropriate regimen of treatment. Microphotographs of Chlamydia trachomatis colonies in the blood leukocyte culture and electron microphotographs of different stages of chlamydial life cycle in the host cell in vitro are presented.

Searching for sexually transmitted infections by midstream urine pooling after exclusion of urinary tract infection: A cost-effectiveness analysis.

We aimed to evaluate the cost-effectiveness of screening for sexually transmitted infections (STI), Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, and Trichomonas vaginalis in patients with suspected urinary tract infection (UTI) but negative urine cultures, using a pooled sampling method. A cohort of 200 patients was analyzed. A decision tree model based on cost-effectiveness was used to evaluate the following five diagnostic strategies: (A) no screening;(B) screening only men;(C) screening only women;(D) screening men and women with high leukocyte counts (>70cells/µL);(E) screening all men and women.

Lymphogranuloma venereum (LGV) is a sexually transmitted infection typically caused by serovars L1-L3 of . These serovars are tissue-invasive with a preponderance for lymphatic spread and can be acquired via unprotected oral, anal, or vaginal sex. We present the case of a 23-year-old with a prior history of syphilis admitted with four weeks of progressively enlarging painful right cervical lymphadenopathy.

Introduction: Sexually transmitted infections (STIs) in pregnancy are associated with an increased risk of vertical HIV transmission and adverse pregnancy and birth outcomes. In South Africa, syndromic management is the standard of care for STI management. We assessed the potential impact of point-of-care (POC) screening for curable STIs (Chlamydia trachomatis [CT], Trichomonas vaginalis [TV] and Neisseria gonorrhoeae [NG]) during pregnancy on vertical HIV transmission and adverse pregnancy and birth outcomes.

Background: Previous investigations into the causal relationship between infections and systemic lupus erythematosus (SLE) have yielded controversial results. This study delves into the bidirectional causal relationships between various infectious agents and SLE, employing two-sample Mendelian randomization (MR) from an immunological perspective.
Methods: Utilizing genome-wide association study (GWAS) data for 46 antibody-mediated immune responses (AMIRs) to 13 pathogens and three distinct SLE datasets, we employed Bayesian Weighted MR (BWMR) and inverse variance weighted (IVW) methods to ascertain causal links, supplemented by meta-analysis to resolve inconsistencies.
