Mycoplasma pneumoniae is a bacterium that lacks a cell wall. It produces infections all It produces infections world-wide, in epidemic outbreaks every 4-7 years, or endemically. Its clinical manifestations occur mostly in the respiratory tract and it is a common cause of atypical pneumonia. The treatment is with macrolides, tetracyclines or fluoroquinolones. Since 2000, an increase in resistance to macrolides has been detected worldwide, being more frequent in Asia. In Europe the frequency of resistance ranges between 1% and 25%, depending on the country. Molecular techniques and serology techniques provides very high sensitivity in diagnostic confirmation, being very useful for detecting and controlling M. pneumoniae outbreaks. The detection of resistance to macrolides requires a sequencing technique.

Objective: Chronic bacterial prostatitis (CBP) is an entity of difficult clinical diagnosis and treatment, being the microbiological study of semen the main diagnostic test. This study aimed to determine the etiology and antibiotic resistance in patients with symptomatic bacteriospermia (SBP) in our environment.

Methods: A cross-sectional and retrospective descriptive study has been carried out from a Regional Hospital of the Spanish Southeast. The participants were patients assisted in the consultations of the Hospital with clinic compatible with CBP, between 2016 and 2021. The interventions were collection and analysis of the results derived from the microbiological study of the semen sample. The main determinations were the etiology and rate of antibiotic resistance of BPS episodes are analyzed.

Results: The main isolated microorganism is Enterococcus faecalis (34.89%), followed by Ureaplasma spp. (13.74%) and Escherichia coli (10.98%). The rate of antibiotic resistance of E. faecalis to quinolones (11%) is lower than previous studies, while for E. coli it has been higher (35%). The low rate of resistance shown by E. faecalis and E. coli to fosfomycin and nitrofurantoin stands out.

Conclusions: In the SBP, gram-positive and atypical bacteria are established as the main causative agents of this entity. This forces us to rethink the therapeutic strategy used, which will avoid the increase in antibiotic resistance, recurrences, and chronicity of this pathology.

Herpes zoster infection (HZ) is an important public health problem due to its high incidence and frequent complications, especially post-herpetic neuropathy . The incidence of HZ increases with age and is more frequent in immunocompromised patients. It is estimated that at least 60,000 people develop HZ each year in Spain. The usual forms of HZ are so clinically characteristic that they do not usually require microbiological confirmation, which is reserved for cases without cutaneous manifestations or with atypical presentation. There are currently two vaccines approved by the regulatory agencies and marketed in Spain to prevent the onset of HZ and its complications. The first (Zostavax®) was marketed by the company MSD and licensed in Europe in 2006 and is a live attenuated virus vaccine that is administered in a single dose, while the second (Shingrix®) is a recombinant vaccine, marketed in 2017 and requires two doses. While the former cannot be administered to immunocompromised persons, the latter can be prescribed to any group of adults. The criteria for the indication and financing of these vaccines have not been uniform in the various autonomous communities of Spain. These and other aspects of HZ have been discussed by a group of experts from the Illustrious Official College of Physicians of Madrid (ICOMEM) whose criteria and opinions are included in this paper.

Objective: Mycoplasma genitalium causes persistent sexually transmitted infections. The aims of this study were to estimate the prevalence of resistances to macrolides and fluoroquinolones in M. genitalium and the sexually transmitted coinfections in patients at Hospital Universitario La Paz (Madrid, Spain).

Methods: Patients attended between January and October 2021 were studied. Screening for sexually transmitted pathogens and detection of 23S rRNA and parC genes mutations were performed by real-time PCR (Allplex,SeegeneTM).

Results: A total of 1,518 females and 1,136 males were studied. The prevalence of M. genitalium was 2.1%. The macrolides resistance rate was 51.8%. The mutations found were A2059G, A2058T and A2058G. The rate of resistance to fluoroquinolones was 17.8% being the G248T mutation (S83I) the most frequent. Seven males had some sexual transmitted coinfection.

Conclusions: Although the percentage of M. genitalium infections is low, the high rate of resistance to macrolides makes it necessary to revise the protocols for diagnosis and empirical treatment of sexually transmitted infections. The use of fluoroquinolones is appropriate after screening of macrolide resistance profile.

Objective: In the bacterial etiology of severe acute infectious diarrhea, except that caused by Clostridioides difficile, most of them have an invasive character and antibiotic treatment will be necessary in specific situations. Shigella is a classic pathogen, in which it is crucial to know the sensitivity to different classic and alternative antimicrobials. The objective of this work was to analyze the presence of shigellosis and the rate of antibiotic resistance.

Methods: A descriptive-retrospective study of the reports of shigellosis of stool cultures issued between January 2016 and April 2022 was conducted.

Results: A total of 34 episodes (16 -47.1%- by Shigella sonnei) were observed, as of 2018. There were only 2 pediatric cases. The overall resistance rate to azithromycin, trimethoprim-sulfamethoxazole and ciprofloxacin was 52.9%, 64.7% and 44.1%, respectively. 26.5% were resistant to the 3 groups of antibiotics. There was a higher rate of resistance for S. sonnei. The emergence of resistance to cephalosporins in recent years stands out. Episodes of multidrug-resistant shigellosis were detected between 2020 (1 by S. flexneri) and 2022 (4 by S. sonnei).

Conclusions: The episodes of shigellosis are emerging in our environment with a higher rate of multi-resistance. In this context, current empirical treatments for acute enteroinvasive enteritis are at risk of failure, if necessary.

Objective: To describe and quantify resource use and direct health costs associated with skin and skin structure infections (SSSIs) caused by Gram-positive bacteria in adults receiving outpatient parenteral antimicrobial therapy (OPAT), administered by Hospital at Home units (HaH) in Spain.

Methods: Observational, multicenter, retrospective study. We included patients of both sexes included in the HaH-based OPAT Registry during 2011 to 2017 who were hospitalized due to SSSIs caused by Gram-positive bacteria. Resource use included home visits (nurses and physician), emergency room visits, conventional hospitalization stay, HaH stay and antibiotic treatment. Costs were quantified by multiplying the natural units of the resources by the corresponding unit cost. All costs were updated to 2019 euros.

Results: We included 194 episodes in 189 patients from 24 Spanish hospitals. The most frequent main diagnoses were cellulitis (26.8%) and surgical wound infection (24.2%), and 94% of episodes resulted in clinical improvement or cure after treatment. The median HaH stay was 13 days (interquartile range [IR]:8-22.7), and the conventional hospitalization stay was 5 days (IR: 1-10.7). The mean total cost attributable to the complete infectious process was €7,326 (95% confidence interval: €6,316-€8,416).

Conclusions: Our results suggest that OPAT administered by HaH is a safe and efficient alternative for the management of these infections and could lead to lower costs compared with hospital admission.
