Urogenital Chlamydia trachomatis infections

PubMed ID: 1762596Urogenital Chlamydia trachomatis infections are the most common sexually transmitted diseases which have shown a significant increase in the last few years. This organism presents a major health problem in many countries. It is recognized as the cause of both complicated and uncomplicated infections in men, women and infants passing through an infected birth canal. Tissue culture is accepted as the gold standard in the diagnosis of chlamydial infections. But, since this technique is expensive and cumbersome, antigen detection tests such as DFA and EIA are more widely used. Tetracyclines and erythromycines are the first-choice antimicrobials in the treatment of chlamydial infections

Evaluation of a direct fluorescent antibody test for detection of Chlamydia trachomatis in endocervical specimens

PubMed ID: 1930969A total of 160 endocervical specimens collected from 72 symptomatic and 82 asymptomatic women attending a gynecology outpatient clinic were investigated for genital Chlamydia trachomatis infection by the use of tissue culture and DFA test. The infection rate was 42% for symptomatic and 23% for asymptomatic patient groups. The sensitivity rates of the DFA test in the symptomatic and asymptomatic groups were 84% and 75%), while the specificity rates were 89% and 95%, respectively. The DFA test had an overall sensitivity of 80% and specificity of 93%. There was 90% agreement between the two techniques. Therefore, DFA is recommended as an alternative to tissue culture where laboratory facilities are limited and genital chlamydial infections are highly prevalent. 1991 Acta Pathologica, Microbiologica et Immunologica Scandinavic

Chlamydia trachomatis in conjunctival specimens [Konjonktival örneklerde Chlamydia trachomatis araştirilmasi.]

PubMed ID: 8502183One hundred two patients with signs and symptoms of conjunctivitis and 45 asymptomatic subjects were screened for Chlamydia trachomatis using a direct fluorescent antibody test. 26.5% of the symptomatic and 6.6% of the asymptomatic patients were positive for C.trachomatis. The follicular response rate was significantly higher (p < 0.05) in the symptomatic group than in the asymptomatic population (48.1% and 29.3% respectively). This finding correlated well with chlamydial conjunctivitis

Programmatic mapping and size estimation of female sex workers, transgender sex workers and men who have sex with men in İ stanbul and Ankara, Turkey

2-s2.0-85103505275Objectives: Despite a growing HIV threat, there is no definition and characterisation of key populations (KPs), who could be the major drivers of the epidemic in Turkey. We used programmatic mapping to identify locations where KPs congregate, estimate their numbers and understand their operational dynamics to develop appropriate HIV programme implementation strategies. Methods: Female and transgender sex workers (FSWs and TGSWs), and men who have sex with men (MSM) were studied in İ stanbul and Ankara. Within each district, hot spots were identified by interviewing key informants and a crude spot list in each district was developed. The spot validation process was led by KP members who facilitated spot access and interviews of KPs associated with that spot. Final estimates were derived by aggregating the estimated number of KPs at all spots, which was adjusted for the proportion of KPs who visit multiple spots, and for the proportion of KPs who do not visit spots. Results: FSWs were the largest KP identified in İ stanbul with an estimate of 30 447 (5.8/1000 women), followed by 15 780 TGSWs (2.9/1000 men) and 11 656 MSM (2.1/1000). The corresponding numbers in Ankara were 9945 FSWs (5.2/1000 women), 1770 TGSWs (1/1000 men) and 5018 MSM (2.5/1000 men). Each KP had unique typologies based on the way they find and interact with sex partners. MSM were mostly hidden and a higher proportion operated through internet and phone-based applications. Night time was the peak time with Friday, Saturday and Sunday being the peak days of activity in both İ stanbul and Ankara. Conclusions: This study has highlighted the presence of a substantial number of FSWs, TGSW and MSM in İ stanbul and Ankara. The information obtained from this study can be used to set priorities for resource allocation and provide HIV prevention services where coverage could be the highest. © Author(s) (or their employer(s)) 2021.

Chlamydial infection in infants

WOS: A1996VH20200010PubMed ID: 8816036Conjunctival and nasopharyngeal samples were collected from 51 infants aged 1 month-1 year, who have been hospitalized for lower respiratory tract disease which had begun on the 4-12th week of life and has shown recurrences since then. Acute period blood samples were available from 42 of these children. Chlamydia tuachomatis antigen was searched for in the conjunctival and nasopharyngeal specimens by a direct fluorescence test (MikroTrak, Syva Co.), and serum anti-chlamydial IgM antibodies were detected by enzyme immunoassay (Sere ELISA Chlamydia, Savyon Diagnostics). Chlamydia trachomatis was detected from at least one site in 20 children, and 15 children were positive for anti-chlamydial IgM antibodies. Serum samples were available in 16 of 20 children who were positive for C. trachomatis antigens, and 12 had IgM antibodies. Three infants who were antigen negative, also had anti-chlamydial antibodies. Whether antigen positive or not, an patients with antichlamydial antibodies were considered to have pneumoniae due to C. trachomatis, and those who had only antigens without any antibodies, to be superficially infected and carry the organism symptomatically or asymptomatically

Detection of respiratory syncytial virus in children in the 1993-94 winter season in Izmir, Turkey, by two diagnostic methods

PubMed ID: 7833009Respiratory syncytial virus (RSV) infection was searched for in 65 children between 2 months and 2 years of age hospitalized with the presumptive diagnosis of acute bronchiolitis, and in 35 children aged 6 months to 8 years with upper respiratory tract symptoms, by direct fluorescent antibody (DFA) test and cell culture. RSV infection was detected in 29.2% of the first and in 11.4% of the second group. The overall positivity rate was 23%. The sensitivity and the specificity of the commercially available DFA test in comparison with cell culture were 81.8% and 92.5%, respectively. © 1994 APMI
