ABSTRACT
La infección por Neisseria gonorrhoeae (NG) es considerada de alta prioridad en salud pública, por su capacidad para desarrollar resistencia a la mayoría de los antibióticos empleados para tratarla. La presentación anorrectal suele ser asintomática y frecuente en hombres que tienen sexo con hombres (HSH). En Argentina, se recomienda terapia antibiótica dual (ceftriaxona+azitromicina/doxiciclina) como primera línea empírica. Este estudio observacional y retrospectivo se realizó para evaluar el porcentaje de positividad de NG anorrectal, el perfil de sensibilidad a penicilina, tetraciclina, ciprofloxacina, ceftriaxona, cefixima y azitromicina, así como los aspectos clínicos-epidemiológicos de los pacientes atendidos entre 20/10/2015 y 20/03/2020 en consultorios coloproctológicos de un hospital público. Se detectaron 55/436 hisopados rectales positivos para NG (13%). El 95% era HSH y 71%, VIH+. En 18/55 NG fue la única infección. Las co-infecciones más frecuentes: HPV (38%) y C. trachomatis (35%). La sensibilidad a cefalosporinas de espectro extendido (CEE) y a azitromicina fueron 100% y 98%, respectivamente. Se observó la emergencia local de los primeros cinco aislamientos de NG anorrectal con sensibilidad reducida (SR) a CEE, el primer aislamiento con categoría no-sensible a azitromicina y otro con SR a azitromicina concomitantemente con SR a CEE. Aunque el uso de terapia empírica dual sigue siendo adecuado para nuestra institución, se observó la emergencia de aislamientos con SR y NS a las drogas de primera línea, evidenciando la importancia de la vigilancia epidemiológica a nivel local para definir los tratamientos empíricos.
Neisseria gonorrhoeae (NG) infection is considered a high public health priority because of its ability to develop resistance to most of the antibiotics used to treat it.The anorectal presentation is generally asymptomatic and frequent in men who have sex with men (MSM). In Argentina, dual therapy (ceftriaxone+azithromycin/doxycycline) is recommended as first line empiric therapy.This observational and retrospective study was conducted to evaluate the percentage of anorectal NG positivity, the susceptibility profile to penicillin, tetracycline, ciprofloxacin, ceftriaxone, cefixime and azithromycin, as well as the clinical-epidemiological aspects of patients attended between 20/10/2015 and 20/03/2020 in coloproctology of a public hospital.We detected 55/436 positive rectal swabs for NG (13%). 95% were MSM and 71% were PLHIV. In 18/55 NG was the only infection. The most frequent co-infections: HPV (38%) and C. trachomatis (35%).Susceptibility to extended-spectrum cephalosporins (ESCs) and azithromycin was 100% and 98%, respectively. Local emergence of the first five anorectal NG isolates with decreased susceptibility (DS) to ESCs, the first isolate with nonsusceptible category to azithromycin and another with DS to azithromycin concomitantly with DS to ESCs were observed.Although the use of dual empirical therapy continues to be adequate for our institution, the emergence of isolates with DS and NS to first-line drugs was observed, evidencing the importance of epidemiological surveillance at the local level to define empirical treatments

RESUMEN La viruela símica es una enfermedad zoonótica endémica en algunas zonas de África; desde mayo del 2022 se confirmaron múltiples reportes de viruela símica (VS) en países no endémicos. Se presenta el caso de un paciente con antecedente de VIH con exantemas en diversas regiones del cuerpo, con mayor concentración en la región glútea, asociado a adenopatías cervicales y proctitis infecciosa. Se procedió a la toma de la muestra de las lesiones dermatológicas para el estudio molecular de reacción en cadena de la polimerasa en tiempo real (RT-PCR), que confirmó el diagnóstico de VS. La infección por Treponema pallidum y Neisseria gonorrhoeae se identificó mediante serología y cultivo de secreción anal, respectivamente. Se aplicó tratamiento con antibióticos específicos para gonorrea y sífilis, y la VS respondió favorablemente a la terapia sintomática e inmunomoduladora.
ABSTRACT Monkeypox (Mpox) is a zoonotic disease, endemic in some areas of Africa. But since May 2022, multiple cases of Mpox have been reported in non-endemic countries. We present the case of a patient with a history of HIV, as well as rash in several areas of the body, mostly in the gluteal region, associated with cervical lymphadenopathy and infectious proctitis. Diagnosis was confirmed by real-time polymerase chain reaction (RT-PCR) of skin lesion samples. Treponema pallidum and Neisseria gonorrhoeae infection was confirmed by serology and rectal discharge culture, respectively. The patient received antibiotics specific for gonorrhea and syphilis and his condition improved due to symptomatic and immunomodulatory therapy.

Abstract Background Argon plasma coagulation (APC) is a non-tactile ablative therapy that helps to stop rectal bleeding in patients who have developed actinic proctitis after exposure to radiotherapy. This approach seems to be more effective than medications or surgical procedures. Objective To review the literature to verify the effectiveness of APC in the treatment of patients with actinic proctitis induced by radiation therapies. Methods A systematic search was conducted on the following databases: MEDLINE/PubMed, LILACS, SCIELO, and the Cochrane Central Register of Controlled Trials. We identified 81 studies, and 5 of them fulfilled the inclusion criteria. Results In the articles included, a total of 236 patients were evaluated. Most of them were men (67.7%) with a mean age of 66.6 years. Prostate cancer was the main cause of actinic proctitis (67.3%), and control of the bleeding was achieved in 83.3% of the cases, after a mean of 1.67 session of APC. Moreover, 66 patients had complications with the treatment, and rectal pain was the most referred. Conclusions Argon plasma coagulation is a well-tolerated and effective treatment to control rectal bleeding in patients who underwent radiotherapy, and the number of sessions varies from 1 to 2, according to the case.

Malignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to minimize the effects of radiation on the tissues surrounding the neoplastic site; despite those strategies, radiotherapy can still result in serious damage to organs and structures, and these injuries accompany patients throughout their lives. One of the most common damages resulting from pelvic radiotherapy is acute proctitis.The diagnosis is confirmed by visualizing the rectal mucosa through rigid or flexible rectosigmoidoscopy and colonoscopy. The objective of the present study was to review the forms of radiation-induced proctopathytherapy, and to evaluate the results of each method to propose a standardization for the treatment of this pathology. Despite the prevalence of radiation-induced proctopathy, there is no definitive standardized treatment strategy so far. The first approach can be tried with local agents, such as mesalazine and formalin. For refractory cases, control can usually be achieved with argon plasma coagulation, hyperbaric oxygen, and radiofrequency ablation therapies. Regarding the study of radiation-induced proctopathy, there is a lack of robust studies with large samples and standardized therapies to be compared. There is a lack of double-blinded, randomized controlled studies to determine a definitive standard treatment algorithm. (AU)

Resumen La proctitis infecciosa secundaria a una enfermedad de transmisión sexual ha aumentado en incidencia y deben ser consideradas especial-mente en varones homosexuales o bisexuales con síntomas rectales. Presentamos un paciente con una proctitis y enfermedad perianal por Chlamydia trachomatis que podría haber sido diagnosticado con otra enfermedad ano-rectal como es la enfermedad inflamatoria intestinal, si la historia clínica no hubiese sido considerada. Un alto nivel de sospecha es necesario para evitar un diagnóstico incorrecto, retrasar el tratamiento antimicrobiano y el desarrollo de complicaciones.
Abstract Infectious proctitis by sexually transmitted diseases are increasing in incidence and should be considered in homosexual patients with rectal symptoms. In this case, we show a patient with proctitis and perianal disease caused by Chlamydia trachomatis that could be diagnosed as another anorectal disease such as inflammatory bowel disease if the clinical history is not taken into account. A high level of suspicion is crucial, in order to avoid an incorrect diagnosis, delayed antibiotic therapy and the development of complications.

Resumen Objetivo: Describir y caracterizar los aspectos epidemiológicos y clínicos de los pacientes con proctitis infecciosa en nuestro hospital. Materiales y Método: Se trata de un estudio de tipo transversal de pacientes con sintomatología perianal y del canal anal, concordante con proctitis, que consultaron en el policlínico de coloproctología entre enero de 2017 y diciembre de 2018, a quienes se les realizó estudio de secreción anal para confirmar infección de transmisión sexual. Resultados: Son 46 pacientes hombres, 26 años promedio de edad, un 6% heterosexuales. Un 65% había consultado previamente (ninguno a un coloproctólogo). El síntoma más frecuente: ano húmedo (97,8%) y el signo: dermitis perianal (100%). De este grupo, 20 nunca se habían realizado estudio de VIH y 50% resultó ser seropositivo. Presentaban infecciones de transmisión sexual más comunes: Gonorrea (43,4%) y sífilis (31,2%) y en un 32% hubo presencia de más de un germen. Discusión: Los resultados sugieren que la proctitis infecciosa es una patología de pacientes jóvenes quienes tienen relaciones sexuales sin protección, más del 50% no utiliza condón. La mayoría de los pacientes presentan consultas previas con médicos no proctólogos. Los gérmenes con mayor frecuencia que provocan proctitis infecciosa: Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum. Conclusión: La presencia de una dermitis perianal sin respuesta a tratamiento habitual, muy severa y/o en pacientes de riesgo, debe hacer sospechar proctitis infecciosa.
Objective: Describe and characterize epidemiological and clinical aspects of patients with infectious proctitis at our hospital. Materials and Method: This is a cross-sectional study of patients with perianal and anal canal symptoms consistent with proctitis, who consulted at the Clinical Hospital of The University of Chile coloproctology outpatient clinic between January 2017 and December 2018, with perianal and anal canal symptoms, consistent with proctitis, and with confirmed sexually transmitted disease by anal secretion study. Results: Total of 46 patients, all male with average age of 26 years old. 6% heterosexuals. 65% had previous medical consults (none with a proctologist). The most common symptom was wet anus (97.8%), and the most common physical finding was perianal dermatitis (100%). 20 patients had never been tested for HIV, and 50% were positive for this disease. The most common sexually transmitted diseases were gonorrhea (43.4%) and syphilis (31.2%). In 32% of the patients, the culture informed more than one pathogen. Discussion: The results suggest that infectious proctitis is a disease of young patients who have unprotected sex. More than 50% do not use a condom. Most patients have prior consults, but none with a proctologist. The most frequent pathogen that causes infectious proctitis: Neisseria gonorrhoeae, Chlamydia trachomatis, and Treponema pallidum. Conclusion: The presence of severe perianal dermatitis, lack of response to common treatment, and/or in patients with risk factors, infectious proctitis should be suspected.

ABSTRACT Purpose: The present study aimed at testing a new formulation of mesalazine linked to chondroitin sulfate and its components alone in the treatment of actinic proctitis in rats. Methods: Forty-seven female Wistar rats were submitted to pelvic radiation and divided into eight groups: control A, mesalazine A, chondroitin A, and conjugate A, gavage of the according substance two weeks after irradiation and sacrifice three weeks after oral treatment; control C, mesalazine C, chondroitin C, and conjugate C, sacrifice six weeks after oral treatment. The rectum was submitted to histological characterization for each of the findings: inflammatory infiltrate, epithelial degeneration, mucosal necrosis, and fibrosis. Results: The inflammatory infiltrate was more intense in chondroitin A, mesalazine A, and conjugate C. The collagen deposition was less intense in chondroitin A, and mesalazine A, and more intense in control C. Conclusions: Mesalazine and chondroitin alone were efficacious in inducing a delayed inflammatory response, hence reducing the late fibrosis. The conjugate was able to induce an ever more delayed inflammatory response.

Although pelvic radiotherapy has played an important role in the treatment of malignant tumors, it is still difficult to avoid radiation damage within a certain period of time. In 2021, under the joint promotion of Colorectal Surgery Group of Chinese Medical Association Surgery Branch, Colorectal Surgeons Committee of Chinese Medical Doctor Association Surgeons Branch, Colorectal Surgeons Committee of Chinese Medical Doctor Association, and Colorectal Cancer Professional Committee of Chinese Anti-Cancer Association, Expert Group on Diagnosis and Treatment of Radiation Intestinal Injury has updated and formulated the 2021 edition of the "Chinese expert consensus on the multidisciplinary diagnosis and treatment of radiation rectal injury" (hereinafter referred to as "Consensus"). This Consensus edition has major changes compared with the "Chinese consensus on the diagnosis and treatment of radiation proctitis (2018)", which mainly updates in the following aspects: (1) adjusting the name of radiation rectal injury: the term "radiation proctitis" was adjusted to "radiation rectal injury"; (2) advocating the concept of pelvic integral injury and the multidisciplinary diagnosis and treatment model; (3) putting forward the clinical classification of diseases: the classification of the chronic rectal injury includes telangiectasia, ulcer, stenosis and mixed type; (4) carrying out individualized treatment based on the characteristics of the above-mentioned disease classification, and adjusting the recommended level of non-surgical treatment; (5) proposing specific guiding principles and details of surgical treatment: "damage control" and "expanded resection" principles, etc. This new edition (2021) of Consensus further refines the disease analysis and treatment strategies, which not only improves the guiding value of clinical practice, but also provides an important reference for the standardized diagnosis and treatment of radiation rectal injury in China.

RESUMEN La proctitis infecciosa (PI) transmitida sexualmente es un proceso inflamatorio del recto secundario a la infección por gérmenes de transmisión sexual. Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum y el virus herpes simple (VHS) son las causas más comunes. Es más prevalente en hombres que tienen sexo con hombres (HSH) y en pacientes con infección por el virus de inmunodeficiencia humana (VIH), sin embargo, también se diagnostica en heterosexuales por cambios en el comportamiento sexual. La urgencia fecal, el exudado purulento o sanguinolento, la proctalgia y el tenesmo son las manifestaciones clínicas más frecuentes. La historia clínica detallada y un alto índice de sospecha son importantes para establecer el diagnóstico de esta patología; apoyados en los estudios endoscópicos, histológicos, serológicos y microbiológicos. Se recomienda el tratamiento empírico, con antibióticos o antivirales, según la sospecha clínica y siempre deben descartarse otras infecciones de transmisión sexual (ITSs).
ABSTRACT Sexually transmitted infectious proctitis is an inflammatory process of the rectum secondary to infection by sexually transmitted germs. Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum, and herpes simplex virus (HSV) are the most frequently pathogens. Infectious proctitis is more prevalent in men who have sex with men (MSM) and in patients with human immunodeficiency virus (HIV) infection, however, it is also diagnosed in heterosexuals by changes in sexual behavior. Fecal urgency, purulent or bloody exudate, proctalgia, and tenesmus are the most common clinical manifestations. Detailed clinical history and a high index of suspicion are important to establish the diagnosis of this pathology; supported by endoscopic, histological, serological, and microbiological studies. Empirical treatment with antibiotics or antivirals is recommended, depending on clinical suspicion, and other sexually transmitted infections (STIs) should always be ruled out.

Abstract Purpose Changrui enema, a traditional Chinese medicine prescription, is used as a supplementary treatment for acute radiation proctitis (ARP). Herein we explored the inhibition effects of Changrui enema on NF-κB and VEGF in ARP mice. Methods A total of 120 C57BL/6 mice were divided randomly into normal mice group, ARP mice group, western medicine enema group (dexamethasone combined with gentamicin), and Changrui enema group. ARP mice were established by pelvic local irradiation. The expression of IL-1β, NF-κB, VEGF, AQP1, AQP3, p-ERK1/2 and p-JNK was determined by immunohistochemistry or western blot. Results The study firstly found that Changrui enema alleviated ARP mice. The expression of IL-1β, NF-κB, VEGF, AQP1 and p-ERK1/2 was increased in ARP mice, and was reserved by Changrui enema. However, the expression of AQP3 and p-JNK was decreased in ARP mice, and was up-regulated by Changrui enema. Conclusions Changrui enema is an effective treatment with fewer side effects for ARP. The mechanism of Changrui enema may be related to the inhibition of inflammation-induced angiogenesis. Changrui enema inhibits IL-1β and NF-κB expression as well as VEGF expression. Interestingly, AQP1 promotes angiogenesis, while AQP3 inhibits inflammation. Changrui enema probably inhibits AQP1 expression by down-regulating p-ERK1/2, and improves AQP3 expression by up-regulating p-JNK.

Introducción: Las infecciones transmisibles sexualmente (ITS) con afectación anorrectal constituyen un desafío pues las manifestaciones producidas por Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) y Treponema pallidum (TP) son similares. Objetivo: Evaluar si las manifestaciones anorrectales debidas a CT, NG y TP asociadas al examen proctológico permiten diagnóstico certero, sin estudios complementarios. Pacientes y método: Estudio retrospectivo. Revisión de registros de pacientes atendidos en consultorio coloproctológico. Periodo: 01/08/2015-01/07/2016. Se incluyeron pacientes con diagnóstico de ITS anorrectal, excepto aquellos con HPV únicamente. A todos se les pesquisaron ITS mediante hisopado anal para CT por inmunofluorescencia y para estudio directo y cultivo de NG, VDRL para TP y además HIV. Variables: sexo, edad, HIV, sexo anal, uso de preservativo, motivo de consulta y resultado de estudios efectuados. Resultados: Treinta y cuatro pacientes (32 hombres). Edad mediana 31,5 años (rango: 19-65). Veinticinco pacientes HIV + (73,5%). Veintinueve pacientes (28 hombres) mantenían sexo anal. 91% no usaba preservativo adecuadamente. 65% tuvo una única infección (ITS pura). Se diagnosticaron 14 sífilis (8 puras), 14 clamidiasis (7 puras) y 11 gonococcias (7 puras). Co-infección entre ellas: 9% y con HPV: 26%. La úlcera fue la manifestación en 7/8 casos de sífilis puras (todas dolorosas, excepto una). El resto presentó síntomas variados (condilomas virales atípicos, secreción purulenta y proctorragia). Más del 50% de las gonococias puras (4/7) se manifestó con úlcera, sin embargo, el dolor estuvo presente siempre (8/8) y en tres se asoció secreción purulenta. En cambio, la mitad de los pacientes con clamidiasis puras, se manifestó con proctorragia causada por un tumor rectal/sigmoideo inflamatorio, clínicamente indistinguible de neoplasia maligna. Todos las sífilis y gonococias tuvieron correlato con las pruebas diagnósticas, no así las clamidiasis cuyo diagnóstico no pudo confirmarse en tres casos (37,5%), que respondieron al tratamiento empírico. Conclusión: NG y TP anorrectal provocaron mayormente síntomas similares a los de etiología no venérea y se requirió del laboratorio para el diagnóstico etiológico. La presencia de tumor con biopsia negativa para neoplasia maligna en pacientes de riesgo para ITS obliga a descartar clamidiasis. (AU)
Introduction: Sexually transmitted infections (STIs) are a challenge in medical consultation. The clinical manifestations of infection by Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Treponema pallidum ( TP) share symptoms at anorectal level. This implies the need for a high index of suspicion for diagnosis, which is based on history, physical examination and laboratory tests that not always are accurate or available . Purpose: Assess whether clinical signs of anorectal infections by CT, NG and TP associated with proctologic exams, lead to an accurate etiologic diagnosis without the help of specific laboratory studies. Patients and methods: Observational, retrospective study, based on a review of records of patients treated at the outpatient clinic of the Hospital Fernandez (City of Buenos Aires) department of coloproctology, in the period between August 2015 and July 2016. Patients who underwent STI diagnosis were all considered, but to those whose only diagnosis was infection by human papilloma virus (HPV) were excluded from the analysis. All patients were tested after the three etiologies of STI (anal swab for CT study by immunofluorescence, swabbing for direct study, and cultivation of NG and TP VDRL) and HIV. Variables analyzed: sex, age, presence of HIV infection, practice of receptive anal sex, proper use of condoms, signs and symptoms that prompted the consultation, and results of diagnostic tests. Results: 34 patients (32 men) were included. Median age 31.5 years (range: 19-65, interquartile range: 26-37). Twenty-five patients (73.5%) were HIV+. Twenty-nine patients (28 men) remained receptive anal sex. 91% did not use condoms properly. 65% of infections were pure, without other STI asociada-. 14 cases of syphilis (8 pure), 14 Chlamydia (7 pure) and 11 gonococcias (7puras), including co-infection in 9% of cases, no evidence of a more frequent another co-infection diagnosed. Co-infection with HPV was detected in 9 (26%) cases. The ulcer was the sign in 7/8 cases of pure syphilis (all painful, except one). The rest is expressed by a variety of symptoms (atypical viral warts, purulent and bloody diarrhea). Similarly, just over 50% (4/7) of pure gonococcias demonstrated ulcer, but the pain was always present (8/8 of pure gonococcias) and three associated with purulent discharge. Instead of the ten patients with pure chlamydia, 50% manifested with bloody diarrhea caused by a rectal tumor / inflammatory sigmoid, clinically indistinguishable from malignancy. All cases of syphilis and gonococcal were correlated with diagnostic tests; not those whose diagnosis of chlamydial infection (confirmed in eight and was negative in three, 37.5%) who responded to empiric treatment indicated by the clinical suspicion. Conclusion: While this is a small series, it shows that the NG and TP in the anorectal location mostly caused symptoms similar to those of non-venereal ethology most of the times, and laboratory assistance for etiologic diagnosis was required. The presence of tumor with negative biopsy for malignancy in patients at risk for STIs, leads chlamydia to be ruled out. (AU)

Introducción: Las infecciones transmisibles sexualmente (ITS) son motivo de consulta frecuente, encontrándose Chlamydia trachomatis (CT) entre las prevalentes. Este germen provoca proctitis de diversa gravedad según el biovar involucrado. Los casos más floridos suelen ser ocasionados por el biovar LGV, responsable de la entidad linfogranuloma venéreo. Se desconocen la prevalencia de CT como causa de proctitis en Argentina y los biovares implicados. Con el objetivo de estudiar estas variables, se diseñó un protocolo para detectar y genotipificar CT en pacientes con proctitis infecciosa. Pacientes y métodos: Se incluyeron pacientes mayores de 18 años con cuadro de proctitis infecciosa atendidos en un centro público y otro privado. Se excluyeron pacientes con enfermedad inflamatoria intestinal y radioterapia pelviana. El estudio fue aprobado por un Comité de Ética y los pacientes firmaron un consentimiento informado. En las muestras de hisopado anal se realizó detección y tipificación molecular de CT. Resultados: Entre 31de agosto de 2017 y 31 de mayo de 2018, se incluyeron 56 pacientes (1 mujer, 53 hombres, 2 mujeres trans), 79% HIV+. En 29 casos (52%) se detectó CT. Todos eran hombres que tienen sexo con hombres (HSH) y refirieron practicar sexo anal u oral receptivo no protegido. La mediana de edad de este subgrupo fue de 31 años; 83% HIV+ en tratamiento antirretroviral y mediana de CD4 637 cel/mm3. La coinfección con otras ITS fue del 41% (siendo las más frecuentes HPV, gonococia y sífilis). Los motivos de consulta más frecuentes fueron proctorragia, pujo y tenesmo, proctalgia y secreción. Las manifestaciones clínicas fueron variadas: proctitis, úlcera perianal, tumor endoanal/rectal y absceso/fístula. El 86% de las proctitis correspondió al biovar LGV, siendo 62% moderadas a graves. La mediana de tiempo de evolución hasta el diagnóstico fue 21 días. Los casos más prolongados correspondieron a cuadros clínicos y endoscópicos más graves. La duración del tratamiento se adecuó al biovar involucrado. Todos los pacientes respondieron favorablemente; sin embargo, las dos fístulas perianales requirieron resolución quirúrgica. Conclusiones: Proctitis, úlceras y fístulas son manifestaciones inespecíficas; el hallazgo clínico y endoscópico per se no son suficientes para definir la etiología; sólo una anamnesis minuciosa permite presumir una ITS como agente causal. La tipificación logra definir el biovar, dato fundamental para adecuar el tratamiento, cortar la cadena de transmisión y contar con datos epidemiológicos a nivel local. Como resultado de esta investigación, el Ministerio de Salud de Nación proyectó la emisión de una alerta sobre la presencia de LGV en nuestro medio. Tipo de estudio: Observacional, transversal, analítico, multicéntrico.
Introduction: Sexually transmitted infections (STI) are a frequent reason for consultation, being Chlamydia trachomatis (CT) among the most prevalent ones. It causes proctitis of varying severity depending on the biovar involved. The most severe cases are usually caused by the LGV biovar, responsible for the entity called lymphogranuloma venereum. The prevalence of CT as a cause of proctitis in Argentina and the biovars involved are unknown. In order to study these variables, a protocol was designed to detect and genotype CT in patients with infectious proctitis. Patients and methods: Patients over 18 years old with infectious proctitis were attended in a public and private center. Patients with inflammatory bowel disease and pelvic radiation therapy were excluded. The study was approved by an Ethics Committee and the patients signed an informed consent. The detection and molecular typing of CT was performed in anal swab samples. Results: Between 31-08-2017 and 31-05-2018, 56 patients were included (1 woman, 53 men, 2 trans women), 79% HIV +. In 29 cases (52%) CT was detected. All were MSM and reported to practice unprotected receptive oral or anal sex. The median age of this subgroup was 31 years; 83% HIV + on antiretroviral treatment and median CD4 637 cel / mm3. The coinfection with other STIs was present 41% (the most frequent were HPV, gonococcal and syphilis). The most frequent symptoms were bleeding, tenesmus, proctalgia and secretion. The clinical manifestations were varied: proctitis, perianal ulcer, endoanal / rectal tumor and abscess / anal fistula. 86% of the proctitis corresponded to the LGV biovar, being 62% moderate to severe. The median time of evolution until the diagnosis was 21 days. The most prolonged cases corresponded to more severe clinical and endoscopic symptoms. The duration of the treatment was adapted to the biovar involved. All patients responded favorably; however, the two perianal fistulas required surgical resolution. Conclusions: Proctitis, ulcers and fistulas are nonspecific manifestations; the clinical and endoscopic findings per se are not sufficient to define the etiology; only a meticulous anamnesis allows us to presume an STI as a causative agent. The typification allows to define the biovar, a fundamental data to adapt the treatment, stop chain of transmission and provides local epidemiological data. As a result of this investigation, the Ministry of Health of the Argentina issued an alert about the presence of LGV in our country. Type of study: Observational, cross-sectional, analytical, multicenter study.

Desde 2003, en los países desarrollados han aumentado las comunicaciones sobre casos de linfogranuloma venéreo con cuadros clínicos diferentes de la forma inguinal clásica. Las presentaciones anorrectales, hasta hace poco atípicas, predominan en hombres infectados por HIV que tienen sexo con hombres. El objetivo de este trabajo es informar sobre la presencia de esta infección en la Ciudad Autónoma de Buenos Aires y describir sus variadas manifestaciones clínicas. En el contexto de una pesquisa sistemática de la infección rectal por clamidias, en apenas un trimestre fueron identificados ocho casos de linfogranuloma venéreo por Chlamydia trachomatis biovar LGV en hombres HIV positivos que tienen sexo con hombres. Las manifestaciones anorrectales más frecuentes fueron pujo, tenesmo, urgencia evacuatoria y secreción mucosa o hemopurulenta. En su mayoría presentaban proctitis leve o moderada, acompañada en algunos casos de lesiones perianales. Dados el polimorfismo y la inespecificidad de las manifestaciones clínicas del linfogranuloma venéreo rectal, se advierte sobre la circulación de esta infección en nuestro medio. En caso de detectar Chlamydia trachomatis, es importante genotipificarla para el correcto diagnóstico y tratamiento de la enfermedad y también para su vigilancia epidemiológica. Si la genotipificación no es posible, se debe considerar el caso como producido por el biovar LGV y aplicar el tratamiento correspondiente.
From 2003 to date there has been a rising number of reports from developed countries on cases of lymphogranuloma venereum with anorectal localization in HIV-infected men who have sex with men. This localization differs from the classical inguinal abscesses which are typical of the disease in the tropics. The objective of this work is to document the presence of anorectal lymphogranuloma venereum in Buenos Aires and to describe its varied clinical manifestations. In the context of a systematic survey of rectal chlamydial infection, in just one trimester, eight cases of lymphogranuloma venereum caused by Chlamydia trachomatis biovar LGV were identified in HIV-infected men who have sex with men. The most frequent anorectal manifestations were pus, tenesmus, rectal urgency, and mucous or haemopurulent discharge. The proctitis was mostly mild or moderate and, in some cases, it was accompanied by perianal lesions. Given the great polymorphism and unspecificity of the clinical manifestations of the disease, we warn on the presence of this form of rectal lymphogranuloma venereum in our setting. If Chlamydia trachomatis is detected, it should be genotyped, not only for the correct diagnosis and treatment but also for epidemiological surveillance. Where genotyping is not available, the disease must be considered as caused by the LGV biovar and treated accordingly.

Abstract Purpose: To investigate the prophylactic and therapeutical effects of sildenafil in a model of acute radiation proctitis (ARP). Methods: All experimental procedures of this study was examined by histopathological, immunohistochemical and transmission electron microscopic analysis. Results: Our histopathological evaluations indicated significant increases in lesion severity, cryptic apsis, cryptitis, cryptic distortion, reactive atypia and infiltration depth of the control (proctitis) group. While the prophylaxis group and the treatment group had significantly lower scores. High-dose group showed similar results as prophylaxis group. Histopathological findings of the prophylaxis group was more significant than the treatment group. Immunoreactivities of IL-1β, FGF-2, TNF- α and HIF-1α increased in the control group especially in the epithelial and cryptic regions. On the contrary, sildenafil application caused significant decreases of inflammatory markers in all treatment groups, specifically better results in the prophylaxis group. Conclusion: The sildenafil has anti-inflammatory effects on ARP, as well as protective effects against ARP and the protective effect of sildenafil surpasses its therapeutic effect histopathologically.

Radiation proctitis denotes the radiation damage of rectum caused by radiotherapy to pelvic malignancy. The clinical practices of radiation proctitis should be fully considered from diagnosis, treatment and prevention. In order to determine appropriate treatment strategies, the diagnosis of radiation proctitis should be based on clinical symptoms, endoscopic findings, imaging and histopathology to assess severity of symptoms and stage of disease. In terms of treatment decisions, non-surgical interventions are generally applied to relieve major symptoms and avoid serious complications. Diverting colostomy and restorative resection are the main surgical treatments for patients with recurrent symptoms. In terms of prevention, radiation proctitis should be prevented by improvement of radiotherapy technology, physical protection and prophylactic medication. This guide aims to provide guidance for the clinical practices of radiation proctitis in China.
