RESUMO

BACKGROUND: Mycoplasma genitalium is now recognised as an important bacterial sexually transmitted infection. We summarised data from studies of mutations associated with macrolide and fluoroquinolone resistance in M genitalium to establish the prevalence of resistance. We also investigated temporal trends in resistance and aimed to establish the association between resistance and geographical location. METHODS: In this systematic review and meta-analysis, we searched PubMed, Embase, and MEDLINE for studies that included data for the prevalence of mutations associated with macrolide and fluoroquinolone resistance in M genitalium published in any language up to Jan 7, 2019. We defined prevalence as the proportion of M genitalium samples positive for key mutations associated with azithromycin resistance (23S rRNA gene, position 2058 or 2059) or moxifloxacin resistance (S83R, S83I, D87N, or D87Y in parC), or both, among all M genitalium samples that were successfully characterised. We used random-effects meta-analyses to calculate summary estimates of prevalence. Subgroup and meta-regression analyses by WHO region and time period were done. This study was registered with PROSPERO, number CRD42016050370. RESULTS: Overall, 59 studies from 21 countries met the inclusion criteria for our study: 57 studies of macrolide resistance (8966 samples), 25 of fluoroquinolone resistance (4003 samples), and 22 of dual resistance to macrolides and fluoroquinolones (3280 samples). The summary prevalence of mutations associated with macrolide resistance among M genitalium samples was 35·5% (95% CI 28·8-42·5); prevalence increased from 10·0% (95% CI 2·6-20·1%) before 2010, to 51·4% (40·3-62·4%) in 2016-17 (p<0·0001). Prevalence of mutations associated with macrolide resistance was significantly greater in samples in the WHO Western Pacific and Americas regions than in those from the WHO European region. The overall prevalence of mutations associated with fluoroquinolone resistance in M genitalium samples was 7·7% (95% CI 4·5-11·4%). Prevalence did not change significantly over time, but was significantly higher in the Western Pacific region than in the European region. Overall, the prevalence of both mutations associated with macrolide resistance and those associated with fluoroquinolone resistance among M genitalium samples was 2·8% (1·3-4·7%). The prevalence of dual resistance did not change significantly over time, and did not vary significantly by geographical region. INTERPRETATION: Global surveillance and measures to optimise the efficacy of treatments-including resistance-guided strategies, new antimicrobials, and antimicrobial combination approaches-are urgently needed to ensure cure in a high proportion of M genitalium infections and to prevent further spread of resistant strains.

RESUMO

RESUMO Objetivos Identificar as condutas de saúde dos homens jovens universitários; conhecer a percepção dos homens jovens universitários sobre o cuidar de sua saúde; e descrever as práticas adotadas para a prevenção das infecções sexualmente transmissíveis. Método Estudo descritivo e exploratório, com abordagem qualitativa, desenvolvido com 25 jovens universitários entre 18-29 anos numa universidade pública do Rio de Janeiro. Para análise dos dados, utilizou-se a técnica de análise de conteúdo. Resultados Os homens jovens universitários percebem o cuidar como feminino, desconhecendo suas próprias particularidades, com a percepção de que não adoecem e, com isso, só procuram o serviço de saúde em situações de emergência. Conclusão e Implicações para a prática Existem desafios a serem vencidos na prática da assistência, como a visão de invulnerabilidade desses homens, a ausência na busca pelos serviços de saúde, o despreparo dos serviços de saúde para atender às necessidades desses jovens, com base em estratégias que contemplem, de forma singular e holística, essa população. As brechas identificadas no estudo permitem levantar futuras questões e provocar mudanças de atitudes voltadas a situações do contexto masculino, a fim de reverter vulnerabilidades ainda existentes e, também, as consequências dessas atitudes na saúde desses homens.

ABSTRACT Objectives To identify the health behaviors of university students, young men, to know the perception of them about caring for their health, and to describe practices adopted for the prevention of sexually transmitted infections. Method Descriptive and exploratory study, with a qualitative approach, developed with 25 students aged 18-29 at a public university in Rio de Janeiro. To the data analyzed, the content analysis technique was applied. Results Those university students perceived caring as a female practice. They were unaware of their health peculiarities, with the perception that they do not get sick. Because of that, they only seek health services in emergency health conditions. Conclusion and Implications for practice There are challenges to overcome in the practice of men's care. As the vision of the invulnerability of these men, there is an absence in the search for health services.Furthermore, a sort of unprepared health services does not meet the needs of these young people through strategies that contemplate them uniquely and holistically. The gaps identified allow us to raise inevitable questions and bring about changes in attitudes toward situations in the male context. It is necessary to reverse existing vulnerabilities and consequences on the men's health of these men.

RESUMO

BACKGROUND: The increasing prevalence of macrolide resistant Mycoplasma genitalium is a major concern worldwide. In Cuba, several cases of clinical treatment failure with 1 g single dose and extended azithromycin regimen have been detected and the aim of the present investigation was to retrospectively determine the prevalence of macrolide-resistance mediating mutations (MRMM) in M. genitalium-positive samples conserved at the Cuban National Reference Laboratory of Mycoplasma Research between 2009 and 2016. METHODS: A total of 280 positive DNA extracts were analysed by a 5' nuclease assay for detection of M. genitalium MRMM. Ten urogenital specimens from patients with azithromycin treatment failure and MRMM were inoculated in Vero cell to obtain the isolates for subsequent determination of antimicrobial susceptibility. RESULTS: The overall prevalence of MRMM was 32%. No MRMM was detected in samples collected between 2009 and 2013 but since 2014 a dramatic increase to 90% (95% CI, 76-96%) in 2016 was seen. Three new M. genitalium isolates were isolated in Vero cell cultures and confirmed phenotypic resistance to macrolides in a cell-culture assisted susceptibility test. Preliminary observations suggest that combination therapy with levofloxacin and doxycycline may represent an affordable option for treatment of macrolide resistant M. genitalium infections. CONCLUSIONS: This investigation showed the rapid emergence and high prevalence of MRMM in M. genitalium-infected patients in Cuba and confirmed the phenotypic resistance in isolates carrying MRMM. We suggest that Cuban guidelines for sexually transmitted infections are modified to include testing for M. genitalium and detection of MRMM in patients with failure of syndromic treatment, to ensure that in these cases, the treatment will be guided by etiologic diagnosis.

RESUMO

Bacterial sexually transmitted infections are widespread and common, with Neisseria gonorrhoeae (gonorrhea) and Chlamydia trachomatis (chlamydia) being the two most frequent causes. If left untreated, both infections can cause pelvic inflammatory disease, infertility, ectopic pregnancy, and other sequelae. The recommended treatment for gonorrhea is ceftriaxone plus azithromycin (to empirically treat chlamydial coinfections). Antibiotic resistance to all existing therapies has developed in gonorrheal infections. The need for new antibiotics is great, but the pipeline for new drugs is alarmingly small. The aminomethyl spectinomycins, a new class of semisynthetic analogs of the antibiotic spectinomycin, were developed on the basis of a computational analysis of the spectinomycin binding site of the bacterial 30S ribosome and structure-guided synthesis. The compounds display particular potency against common respiratory tract pathogens as well as the sexually transmitted pathogens that cause gonorrhea and chlamydia. Here, we demonstrate the in vitro potencies of several compounds of this class against both bacterial species; the compounds displayed increased potencies against N. gonorrhoeae compared to that of spectinomycin and, significantly, demonstrated activity against C. trachomatis that is not observed with spectinomycin. Efficacies of the compounds were compared to those of spectinomycin and gentamicin in a murine model of infection caused by ceftriaxone/azithromycin-resistant N. gonorrhoeae; the aminomethyl spectinomycins significantly reduced the colonization load and were as potent as the comparator compounds. In summary, data produced by this study support aminomethyl spectinomycins as a promising replacement for spectinomycin and antibiotics such as ceftriaxone for treating drug-resistant gonorrhea, with the added benefit of treating chlamydial coinfections.

RESUMO

Mycoplasma genitalium is a sexually transmitted infection ordinarily treated with azithromycin. Emerging resistance to macrolide is linked to mutations in the 23S rRNA gene. We analysed the frequency of such mutations of M. genitalium isolates from patients that were symptomatic, and from sexual partners of symptomatic individuals, from October to December of 2015, in the Skåne Region of Sweden. Mutations were analysed by the use of DNA sequencing. Overall, 11.9% (145/1,311) and 17.0% (116/704) of females and males were positive for M. genitalium, respectively. Macrolide resistant mutations were detected in 13% (31/239) of M. genitalium isolates from first-test patient samples. Twenty-one (8.8%) and 10 (4.2%) of the isolates had point mutations of the 23S-gene at position 2072 and 2071, respectively. Two different M. genitalium isolates were detected simultaneously in two cases. In summary, we found a relatively low rate of macrolide-resistant M. genitalium in the region of Southern Sweden.

RESUMO

The antibiotic spectinomycin is a potent inhibitor of bacterial protein synthesis with a unique mechanism of action and an excellent safety index, but it lacks antibacterial activity against most clinically important pathogens. A series of N-benzyl-substituted 3'-(R)-3'-aminomethyl-3'-hydroxy spectinomycins was developed on the basis of a computational analysis of the aminomethyl spectinomycin binding site and structure-guided synthesis. These compounds had ribosomal inhibition values comparable to spectinomycin but showed increased potency against the common respiratory tract pathogens Streptococcus pneumoniae, Haemophilus influenzae, Legionella pneumophila, and Moraxella catarrhalis, as well as the sexually transmitted bacteria Neisseria gonorrhoeae and Chlamydia trachomatis. Non-ribosome-binding 3'-(S) isomers of the lead compounds demonstrated weak inhibitory activity in in vitro protein translation assays and poor antibacterial activity, indicating that the antibacterial activity of the series remains on target against the ribosome. Compounds also demonstrated no mammalian cytotoxicity, improved microsomal stability, and favorable pharmacokinetic properties in rats. The lead compound from the series exhibited excellent chemical stability superior to spectinomycin; no interaction with a panel of human receptors and drug metabolism enzymes, suggesting low potential for adverse reactions or drug-drug interactions in vivo; activity in vitro against a panel of penicillin-, macrolide-, and cephalosporin-resistant S. pneumoniae clinical isolates; and the ability to cure mice of fatal pneumococcal pneumonia and sepsis at a dose of 5 mg/kg. Together, these studies indicate that N-benzyl aminomethyl spectinomycins are suitable for further development to treat drug-resistant respiratory tract and sexually transmitted bacterial infections.

RESUMO

Microbicides are a new tool, still under investigation, which could help prevent infection by the human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs). Increasing evidence shows that the complexity of sexual transmission of viral pathogens requires the identification of compounds able to block the early events during the cycle of viral infection. In this manuscript we provide a comprehensive review of the different microbicide strategies that have been studied or are currently being considered for STI prevention, particularly emphasizing those having the potential to block HIV infection. The manuscript also reviews the complex process that is required to conduct future clinical studies in humans and concludes with a brief discussion of the strategies that could be part of the immediate future in microbicide research.

RESUMO

BACKGROUND: Few data exist on the efficacy of combined antiretroviral therapy (cART) in semen of human immunodeficiency virus type 1 (HIV-1) infected men who have sex with men (MSM) with sustained control of HIV replication in blood. METHODS: HIV-1 infected MSM on successful cART for >6 months were enrolled. HIV-RNA was quantified in seminal plasma (spVL) and in blood plasma (bpVL) from 2 paired samples collected 4 weeks apart. Relationship between spVL and bpVL (measured by an ultrasensitive assay, LOQ 10 copies/mL), total peripheral blood mononuclear cells (PBMC)-associated HIV-DNA, sexually transmitted infections (STIs), and self-reported socio-behavioral characteristics was assessed using GEE logistic regression. RESULTS: In total, 157 patients were included. Median time with bpVL <50 copies/mL was 3.3 years. spVL was detectable in 23/304 samples (prevalence 7.6%). Median spVL was 145 cp/mL (100-1475). spVL was detectable on the first, on the second, and on both samples in 5, 14, and 2 men, respectively. In sum, 33 individuals (21%) had STIs (asymptomatic in 24/33). Residual bpVL was undetectable by ultrasensitive assay in 225/300 samples (75%). After multivariable adjustments, PBMC-associated HIV-DNA (OR 2.6[1.2; 6.0], for HIV-DNA > 2.5 log10 cp/10(6) PBMC, P = .02), and cannabis use during sexual intercourse (OR 2.8[1.2; 6.7], P = .02) were the only factors associated significantly with spVL. CONCLUSION: We show that HIV-RNA can be detected intermittently in semen of HIV-1 infected MSM despite successful cART. The size of blood HIV-1 reservoir predicted spVL detection. Our results indicated also that the possible effect of cannabis should be taken into account when developing prevention interventions targeted toward HIV-infected MSM on successful cART.

RESUMO

BACKGROUND: The ethnic usage of exotics and indigenous problem plants is a highly debated topic, as legislative requirements over-shadow their potential medicinal value, particularly to treat sexually transmitted infections (STIs). Limited information exists regarding their medicinal value among the Bapedi. OBJECTIVES: To ascertain the importance of exotics and indigenous problem plants in the treatment of STIs, a major global primary health care challenge. METHODS: A field observation and semi-structured questionnaire focussing on species diversity, types of STIs treated and medicinal preparation as well as application was used to collect data from 34 traditional healers. RESULTS: Seven exotics and three indigenous problem species were identified. These species were used to treat four STIs; with Catharanthus roseus illustrating its dominance in the treatment of gonorrhoea. Some medicinal species used by Bapedi traditional healers have been validated through scientific research or through their extensive use by various cultures in South Africa and other parts of Africa. To the best of our knowledge Alternanthera pungens, Caesalpinia decapetala, Cinnamomum verum, and Citrullus lanatus are reported for the first time in the treatment of the investigated STIs. CONCLUSIONS: Exotic and indigenous problem species constitute an important component of the STIs treatment protocol. Their utilization by Bapedi cautions against the narrow-minded approach of indiscriminate eradication, as these species can play a significant role in the primary health care needs of socio-economic vulnerable people.

RESUMO

A novel, one-step electrochemical biosensing technique has been developed by utilizing a strategy in which a biomolecule controls transport of CdS-signaling nanoparticles to the surface of an electrode. The viability of this approach was explored using DNA as a model target biomolecule. The capture and signaling probes both contain nucleic acid sequences that are complementary to the target DNA. The detection chamber consists of a gold matrix modified with the capture probe on the bottom, a glassy carbon (GC) working electrode on the top, and a buffered electrolyte containing the signaling probe conjugated with the CdS nanoparticle. When target DNA is not present in the chamber, the CdS-signaling probe is freely transported to the GC electrode where CdS accumulates during the preconcentration step and undergoes electrochemical anodic stripping voltammetry (ASV) that subsequently generates a current signal during the following oxidative stripping step. On the other hand, target DNA present in the sample undergoes simultaneous hybridization to both the capture and signaling probes in a sandwich-like manner. This phenomenon leads to fixation of the CdS nanoparticles on the bottom of the chamber, thus preventing their electrochemical reduction on the GC electrode. As a result, the electrochemical signal is reduced in the presence of target DNA. Based on the reduction of the current signal, target DNA from C. trachomatis was successfully detected without the need for any complicated secondary procedures. This electrochemical one-step detection method could serve as a conceptually new technology enabling highly convenient biosensing that is applicable to point-of-care testing (POCT).

RESUMO

The study is aimed at investigation of efficacy and safety of a combined effect of laser therapy and vibromagnetotherapy in complex treatment of patients with chronic urethroprostatitis in the presence of sexually transmitted infection (STI). A total of 35 males aged 20 to 51 years entered the study. They were divided into 3 groups. Group 1 received standard basic therapy, group 2 received basic and laser therapy, group 3 - basic treatment and laser plus vibromagnetotherapy. Effectiveness of the treatment was assessed by the evidence obtained from clinical, bacteriological, device and functional examinations. The results of the treatments were evaluated after 2 weeks of the follow-up. It is shown that patients of groups 2 and 3 achieved more pronounced improvement of clinical and laboratory indices, parameters of basal blood flow. Thus, physiotherapy, added to antibacterial treatment, is safe and effective in the treatment of chronic urethroprostatitis and STI.

RESUMO

Antibiotic resistance is an emerging public health problem especially due to the continuous use of antibiotics that selects more aggressive and resistant species. In the present study the authors determined the antibiotic sensitivity of 128 Mycoplasma hominis strains obtained from urethral swabs of male patients (mean age 36 years). The Mycoplasma IST 2 strip was used to test antibiotic susceptibility: 88% of analysed strains were found to be resistant to erythromycin and azithromycin, 75% to clarithromycin, 50% to ofloxacin and ciprofloxacin, and 12% to tetracycline. All strains were susceptible to josamycin, doxycycline and pristinamycin. Results were comparable to those of a recent study by Savarino-Mattei which also showed high resistance of M hominis to macrolide antibiotics and to ciprofloxacin and susceptibility to tetracyclines. Doxycycline is currently the antibiotic of first choice for treating M hominis infections.

RESUMO

Among 254 Neisseria gonorrhoeae isolates from a sexually transmitted infection (STI) clinic in northern Taiwan, 69 isolates were found to contain the mosaic penA (MA) gene and were associated with elevated cefixime and ceftriaxone MICs. Most of these MA gene-harboring isolates were also resistant to penicillin (71.4%) and ciprofloxacin (100%) and were from men who have sex with men (MSM) or from bisexual men (81.2%). Three major sequence types (ST835, ST2180, and ST2253) constituted 55.7% of these isolates. The major sequence types harboring the mosaic penA gene may represent major sexual networks responsible for the emergence/introduction and the spread of the multidrug-resistant clones in Taiwan.

RESUMO

The aim of the study was to assess the effectiveness of an integrated care pathway (ICP) for delivery of evidence-based practice in abortion care. All women re-admitted after an abortion had their records audited for adherence to national and local guidelines using information in the ICP and general gynaecology case notes. A total of 100 women were re-admitted into the gynaecological wards of hospitals in Hull and East Riding of Yorkshire after an abortion, between January 2000 and December 2006. Out of 8,476 medical or surgical induced abortions undertaken at 14 weeks gestation or under, the overall readmission rate was 1.2%. The ICP showed that 97% of women had chlamydia screening prior to the abortion; all women had a contraceptive discussion and 43% left using a long-acting reversible method of contraception (LARC). However, data outside the care pathway was not documented, and hence the standard of care given on readmission was difficult to locate and variable in quality. The ICP clinical record is demonstrated to be a useful tool for high quality record-keeping and ensuring all patients receive the same standard of pre-assessment care. Although this service has an acceptably low-risk profile in terms of re-admission, we propose the addition of a re-admission episode to the current ICP to further enhance clinical care post-abortion.

RESUMO

The efficacy of indigal plus containing indol-3-carbinol, epigallocatexin-3-gallat and Serenoa repens extract in combination with sparfloxacin was studied in a trial with participation of 30 patients with chronic infectious prostatitis associated with intracellular agents. Group 1 (n=15) received indigal plus (2 capsules twice a day for 3 months) and sparfloxacin (200 mg twice a day for 1 month). Group 2 including 15 matched controls received sparfloxacin alone according to the same schedule. The examination included questionnaire survey (IPSS, QoL, NIH-CPSI), blood count, urinalysis, PSA test, microscopy, bacteriological study of prostatic secretion, uroflowmetry, transrectal ultrasound investigation of the prostate with residual urine assay, laser doppleroflowmetry. The examinations were performed on the treatment day 30, 60 and 90. After the antibacterial treatment chlamidia, ureaplasma and E.coli were detected in 13.3, 6.7 and 26.7% patients of the control group, in 6.7, 6.7 and 6.7% patients of the study group, respectively. Thus, the addition of a pathogenetic drug indigal plus to sparfloxacin treatment promoted normalization of apoptosis of the infected cells, led to more effective bacterial eradication, enhanced regression of the symptoms. It is recommended to include indigal plus in a basic scheme of treatment of patients with chronic infectious prostatitis.

RESUMO

All healthcare providers decide in someone else's place, for someone else. In doing so, they take their place in a long long tradition, that of medical paternalism. Patients are treated as children, incapable of making decisions about themselves. How then are we supposed to deal with patients like the street children of the Democratic Republic of the Congo, who are not part of our health-care system, who refuse care and prescriptions? Their refusal of caregivers forces us to seek strategies to dispel the conflicts, adapt outselves to the situation (self-medication, drug sales outside of dispensaries, etc.), but especially to rethink the relation between caregivers and patients. This does not mean abandoning the authoritarian patriarchal model for total relativism; the use of drugs such as antibiotics is and must remain surrounded by all the precautions necessary to avoid the further development of resistance; it does mean training and informing. The task facing us is that of health education and promotion, a long and continuous process, centered on patients and integrated with their care, aimed at making them capable of managing their disease. This procedure is part of a pragmatic approach: beyond the asymmetry involved in any relationship of power, it is essential to establish informed confidence, to look for adhesion and not constraint. Only this pragmatism can incite young people with sexually transmitted diseases (STDs) to use modern medicine and comply with the dosage instructions. Effective treatment of STDs is, according to WHO, one of the most powerful weapons in the battle against AIDS transmission.

RESUMO

In the last decade, cases of sexually-transmitted infections (STIs) have progressively increased in Europe. The reasons for this increase are unclear, but may involve changes in social behavior, migration and international travel, coupled with the emergence of risk groups that have not been taken into sufficient consideration to date. The routine use of molecular diagnostic techniques for many of these infections has solved many problems of sensitivity and the suitability of samples for microbiological diagnosis: non-invasive samples can be used, which has undoubtedly contributed to the increase in the number of cases. Moreover, molecular methods have also been introduced for antibiotic and antiviral susceptibility testing, as well as for molecular characterization of clinical isolates. All of these factors, together with the approval of the vaccine against the human papillomavirus, have changed the landscape of STIs across Europe.

RESUMO

We studied 94 patients with chronic prostatitis (CP) in combination with urogenital chlamydiasis. The patients were divided into three groups. Group 1 consisted of 32 patients with bacterial prostatitis and sexually transmitted infection (STI). They were treated with fromilid in a dose 500 mg twice a day. Group 2 (n = 27) received also low-intensity laser radiation (LILR) on the prostatic gland. Group 3 patients (n = 35) with abacterial prostatitis were given fromilid (500 mg twice a day). We studied prostatic hemodynamics with color doppler mapping. A specific feature of prostatic vascularisation in CP and STI versus healthy subjects is heterogeneous decline of vessels density in ischemic zones with parallel decrease in these vessels diameter. A peripheral prostatic zone in CP patients with STI was characterized by lower vascularisation than central one. This deteriorates the course of the disease. The results of the study show that adjuvant LILR in CP patients with STI raises efficacy of therapy by 11%. Investigation of prostate vascularisation and hemodynamics of its vessels in CP patients with STI using transrectal ultrasonography and dopplerography provide detailed information about prostatic structure allowing for lesion zones. This facilitates choice of an optimal complex treatment with application of LELR in peripheral inflammation of the prostate.
