Comparison of syphilis seropositivity between non-immigrant and immigrant populations in the Anatolian side of Istanbul, Turkiye: Results of five-years retrospective study.

OBJECTIVE: Our study aimed to evaluate the seropositivity for syphilis in non- immigrant and immigrant populations and compare the results regarding demographic data. METHODS: In accordance with the reverse algorithm, syphilis tests were performed between May 2014 and December 2018 in hospitals in our service zone for syphilis screening or symptomatic disease. RESULTS: A total of 135.328 non- immigrant and 6.641 immigrant were screened for syphilis. Seropositivity rates were 1.3% in the non- immigrant and 3.8% in immigrant groups (p=0.0001). There was a statistically significant difference in terms of seropositivity rates between the various age groups in the local group and immigrant groups (except 18 25 age group) (p<0.05). Syphilis seropositivity rates were found to be lower in indigenous population than immigrant groups according to the years tested (p=0.0001). The seropositivity rates were 2.4% and 3.2% among the males (p=0.025) and 0.6% and 4.0% among females (p=0.0001) in non-immigrantand immigrant groups, respectively. Whereas, 0.6% of pregnant women in the local group and 3.7% of pregnant women in immigrant groups were seropositive for syphilis (p=0.0001). Among the HIV positive group, syphilis seropositivity was only observed in the non-immigrant group with a rate of 23.0% (p=0.0001). CONCLUSION: The antibodies against syphilis were found more frequently in immigrants than non-immigrant. Among the HIV positive individuals syphilis seropositivity was only observed in the non-immigrant group.

Distribution of respiratory viruses: Evaluation of multiplex PCR results of 3074 patients.

OBJECTIVE: Early and accurate diagnosis of acute respiratory infections is important because these diseases negatively affect public health and can lead to loss of workforce and an increase in health expenditures. In this study, we aimed to determine the respiration panel multiplex polymerase chain reaction (PCR) test results and seasonal distribution in our region. METHODS: Three thousand and seventy-four patients samples multiplex PCR (Anatolia, Bosphore® Respiratory Pathogens Panel Kit v1) test results, which were sent to our laboratory, from 13 hospitals in our region between January 2018 and December 2018, were evaluated retrospectively. RESULTS: A total of 3074 patients samples, 1465 (48%) were positive and 1609 (52%) were negative test results. The most common factors were rhinovirus 30.2%, influenza A 23.1%, and respiratory syncytial virus (RSV) A/B 19.1%, respectively. When the distribution of these three most common viruses by months is examined, the most frequent months were determined as June for rhinovirus, November for influenza A, and February for RSV A/B. In the period between October and February, there was a significant increase in the positivity level of viral factors. CONCLUSION: The use of molecular methods in the diagnosis of respiratory infections will prevent unnecessary use of antibiotics and ensure correct and rapid treatment.
