Monkeypox outbreak in Madrid (Spain): Clinical and virological aspects.

BACKGROUND: Monkeypox is the most prevalent Orthopoxvirus zoonosis infection since the eradication of smallpox. The current multi-country outbreak involves five WHO regions affecting mainly Europe. Accurate clinical and virological aspects of the disease outside endemic areas are needed. METHODS: We performed an observational study of cases diagnosed in Madrid (Spain) (May/June 2022). Confirmation from vesicular lesions swabs, Orthopoxvirus real-time PCR, sequencing, phylogenetic analysis, and direct detection by Electron microscopy was performed. In addition, a structured epidemiological questionnaire was completed systematically to gather sociodemographic, clinical, and behavioral data from all confirmed cases. FINDINGS: We extracted data from 48 patients, all cisgender men. The median age was 35 years (IQR 29 - 44), and 87.5% were MSM. The most prevalent symptoms were the presence of vesicular-umbilicated and pseudo-pustular skin lesions (93.8%), asthenia (66.6%), and fever (52.1%). In addition, the location of the lesions in the genital or perianal area was related to the role in sexual intercourse (p<0.001). Sequencing analysis indicated the virus circulating in Spain belongs to the western African clade. Like the other European cases in the outbreak, the Spanish isolates are a direct descendant of viruses previously detected in Nigeria, the UK, Singapore, and Israel in 2017-2018. CONCLUSIONS: Monkeypox is an emerging infectious disease in Europe where community transmission is reported, mainly in MSM. The first symptom was skin lesions instead of classical fever and rash. The disease follows a self-limited course, and there have been no cases with a serious presentation or severe complications.

Preventive Efficacy of Tenofovir/Emtricitabine Against Severe Acute Respiratory Syndrome Coronavirus 2 Among Pre-Exposure Prophylaxis Users.

BACKGROUND: The preventive effect that tenofovir/emtricitabine (FTC) could have against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human immunodeficiency virus-negative people is unknown. The objective of this study was to analyze the seroprevalence and clinical manifestations of COVID-19 among users of pre-exposure prophylaxis (PrEP), disoproxil fumarate/FTC (TDF/FTC), or tenofovir alafenamide (TAF)/FTC and to compare it to that of a control group. METHODS: An observational descriptive study of the seroprevalence of antibodies for SARS-CoV-2 among men who have sex with men and transgender women without use of PrEP (Group 1; n = 250) and PrEP users with TDF/FTC (n = 409) or TAF/FTC (n = 91) (Group 2; n = 500) was conducted from May11, 2020 to June 27, 2020. All participants were provided with a structured questionnaire that collected information on the variables to be analyzed, and testing for immunoglobulin G antibodies to SARS-CoV-2 (chemiluminescent microparticle immunoassay) was then carried out. RESULTS: The seroprevalence of SARS-CoV-2 was 9.2% (95% confidence interval [CI], 5.9-13.5) in the group without PrEP and 15.0% (95% CI, 12.0-18.4) in the group with PrEP (P = .026). Among users of TDF/FTC it was 14.7% (95% CI, 11.4-18.5), and in users of TAF/FTC it was 16.5% (95% CI, 9.5-25.7) (P = .661). In those who tested positive for SARS-CoV-2 and receiving PrEP, 57.4% manifested symptoms, compared with 78.3% in the control group (P = .070). In users of TDF/FTC the figure was 53.3% and in users of TAF/FTC the figure was 73.3% (P = .100). The duration of symptoms was 11.5 days in the control group, 9.0 days in PrEP users (P = .116), 7.0 days in users of TDF/FTC, and 13.0 days in users of TAF/FTC (P = .100). CONCLUSIONS: Users of PrEP, TDF/FTC, or TAF/FTC presented a higher seroprevalence to SARS-CoV-2 than the control group. No statistically significant differences were found in relation to clinical manifestations. The PrEP users should use the same prevention measures as those indicated for the general population.

Neuropathic ulcers in leprosy treated with intralesional platelet-rich plasma.

Neuropathic ulcers in leprosy represent a therapeutic challenge for clinicians. Chronic ulcers affect patient health, emotional state and quality of life, causing considerable morbidity and mortality in addition to contributing to significant health care costs. The pathogenesis is mainly related to the abnormally increased pressure in areas such as the sole of the foot, secondary to lack of sensation and deformities induced by peripheral sensory-motor neuropathy. Conventional treatment of these wounds can be slow due to their chronic inflammatory state and the senescence of local reparative cells. Platelet-rich plasma (PRP) may restore the healing process, leading to a reparative phase. We present two patients with four neuropathic leprosy ulcers that have responded satisfactory to PRP treatment. PRP therapy has been growing as a viable treatment alternative for chronic ulcers. However, stronger scientific evidence is required to support its potential benefit for use in chronic wounds.

[Gonorrhea diagnoses in a center for sexually transmitted disease (STD) and their relationship with HIV and other STD, Madrid, 2005]. / Diagnósticos de gonorrea en un centro de infecciones de transmisión sexual y su relación con el virus de la inmunodeficiencia humana y otras infecciones de transmisión sexual, Madrid 2005.

BACKGROUND: The objective of this study is to describe the cases of gonorrhea infection recorded in a center for sexually transmitted diseases (STD) and the factors associated with HIV coinfection. METHODS: Retrospective, descriptive study of all cases of gonorrhea infection diagnosed in 2005. RESULTS: Among 134 cases of gonorrhea, 124 occurred in men who have sex with men. The factors associated with HIV coinfection were a prior history of STD and sexual risk practices under the effects of alcohol and/or drugs (OR, 13.4; 95% CI 1.3-139.1; OR, 39.8; 95% CI 1.3-1194.3). CONCLUSION: An increase in the number of cases of gonorrhea infection is reported, predominantly in the population of men who have sex with men.

[Social and work conditions, risk behavior and prevalence of sexually transmitted diseases among female immigrant prostitutes in Madrid (Spain)]. / Condiciones sociolaborales, conductas de riesgo y prevalencia de infecciones de transmisión sexual en mujeres inmigrantes que ejercen la prostitución en Madrid.

OBJECTIVE: To describe the sociodemographic characteristics, work conditions, sexual behavior, and prevalence of HIV, hepatitis B (HBV), and hepatitis C (HCV) infection and of other sexually transmitted infections among a group of female immigrant prostitutes in Madrid. METHODS: We performed a descriptive study of a group of immigrant women who worked as prostitutes and who attended a sexually transmitted diseases (STD) clinic in Madrid in 1999 and 2000. Information was collected on sociodemographic characteristics, work conditions, use of injected drugs, and sexual practices with their clients and in their private lives. The services provided included screening for the main STDs and serological studies for HIV, HBV and HCV. RESULTS: A total of 579 female immigrants were analyzed. The mean age was 28.7 years. Ninety-six percent were from Latin America. None reported having consumed injected drugs. They began to work as prostitutes at a mean age of 27.4 years and 93.3% of them began in Spain. In the previous month, 98% had always used condoms for vaginal and anal penetrations with their clients and 17.6% had used them in their private sexual relations. Thirty percent reported condom breakage during intercourse. The prevalence of HIV and HCV infection was 0.2 and 0.9%, respectively; 8.1% showed HIV anticore antibodies and 0.5% showed surface antigens. An ulcerative STD was diagnosed in 2.1% and a non-ulcerative STD was diagnosed in 16%. CONCLUSIONS: Condoms are generally used with clients although the frequency of breakage is high. Condom use in prostitutes personal lives is dramatically lower. The prevalence of markers for HIV, HBV and HCV is low and the frequency of STD is moderate.
