Donovanosis

Abstract Donovanosis is a chronic, progressive, and indolent bacterial disease that affects the skin and mucous membranes of the genital and perigenital regions, often associated with sexual transmission, and with low infectivity. The malignant transformation of donovanosis lesions occurs exceptionally, as is usually seen in long-term ulcerations.

Donovanosis.

Donovanosis is a chronic, progressive, and indolent bacterial disease that affects the skin and mucous membranes of the genital and perigenital regions, often associated with sexual transmission, and with low infectivity. The malignant transformation of donovanosis lesions occurs exceptionally, as is usually seen in long-term ulcerations.

The changing epidemiology of genital ulcer disease in South Africa: has donovanosis been eliminated?

OBJECTIVES: We used an in-house molecular assay for the detection of Klebsiella granulomatis in ulcer specimens collected over a 12-year surveillance period in order to determine whether a diagnosis of donovanosis could be ascribed to genital ulcer disease (GUD) of unknown aetiology in our setting. METHODS: Between 2007 and 2018, a total of 974 genital ulcer specimens with no previously identified sexually transmitted (STI) pathogens were selected from STI aetiological surveys conducted in all nine provinces of South Africa. Giemsa-stained ulcer smears from the same participants had previously been routinely analysed for the presence of typical Donovan bodies within large mononuclear cells. A Klebsiella screening assay targeting the phoE (phosphate porin) gene was used in combination with restriction digest analysis and sequencing to confirm the presence of K. granulomatis. RESULTS: The Klebsiella screening assay tested positive in 19/974 (2.0%) genital ulcer specimens. Restriction digest analysis and nucleotide sequencing of the phoE gene confirmed that none of these specimens was positive for K. granulomatis DNA. Similarly, Donovan bodies were not identified in the Giemsa stained ulcer smears of these specimens. CONCLUSIONS: This is the first study to assess K. granulomatis as a cause of genital ulceration in South Africa over a 12-year surveillance period using molecular methods. The results demonstrate that K. granulomatis is no longer a prevalent cause of GUD in our population.

Sexually Transmitted Diseases in the Emergency Department.

Sexually transmitted diseases (STDs) continue to be underrecognized leading to devastating health and economic consequences. Emergency clinicians play an important role in diagnosing and managing STDs and in improving health care outcomes for both the patient and their partners. In addition, antibiotic resistance and emerging infections continue to challenge providers in clinical practice. This review focuses on the cause, history, physical examination, diagnostic studies, and treatment strategies for bacterial vaginosis, chlamydia, genital herpes, gonorrhea, human papillomavirus, granuloma inguinale, Lymphogranuloma Venereum, Mycoplasma genitalium, syphilis, and trichomoniasis.

Donovanosis in a child victim of sexual abuse: response to doxycycline treatment.

Donovanosis is a chronic infectious disease caused by the Gram-negative bacteria Klebsiella granulomatis, which mainly affects the skin and mucous membranes of the genital, perigenital, and inguinal regions. Also known as venereal granuloma or granuloma inguinale, it is endemic in tropical and subtropical regions of the globe and often associated with sexual transmission. We report the case of an 11-year-old female victim of chronic sexual abuse, who was diagnosed with donovanosis and presented a good therapeutic response to doxycycline.

Donovanosis in a child victim of sexual abuse: response to doxycycline treatment

Abstract: Donovanosis is a chronic infectious disease caused by the Gram-negative bacteria Klebsiella granulomatis, which mainly affects the skin and mucous membranes of the genital, perigenital, and inguinal regions. Also known as venereal granuloma or granuloma inguinale, it is endemic in tropical and subtropical regions of the globe and often associated with sexual transmission. We report the case of an 11-year-old female victim of chronic sexual abuse, who was diagnosed with donovanosis and presented a good therapeutic response to doxycycline.

2018 UK national guideline for the management of donovanosis.

The objective of this guideline is to provide guidance for the diagnosis and management of donovanosis, a now rare sexually transmitted infection. This guidance is primarily for professionals working in UK Sexual Health services (although others may find it useful) and refers to the management of individuals presenting with possible symptoms of donovanosis who are over the age of 16. An updated literature review since the last Clinical Effectiveness Group (CEG) guideline produced for this condition in 2011 has shown few new developments. Most reports in the literature relate to cases of unusual presentations of the condition.

Donovanosis With Bowen Disease.

A 45-year-old farmer presented with ulcers and plaques over his scrotum for the past 4 to 5 years. The condition started as a small lesion on the shaft of the penis, which improved with treatment; however, after 2 to 3 months, papulonodular lesions developed on the scrotum, which increased in size and subsequently broke down to form ulcers. He denied drug abuse but had a history of multiple unprotected sexual exposures. He was prescribed oral antibiotics, which improved the lesions, but he failed to take the antibiotics for more than a week. He also used powders, lotions, and salves (exact nature not known), which did not help and sometimes even burned the skin. After stopping the medicine, he developed new lesions that followed a similar course. Examination revealed nontender ulcers on the scrotum with raised, rolled-out margins and pale red, granulation tissue that bled on touch (Figure 1). In addition, there were nodules with a pinkish red granular surface and scaly erythematous plaques on the scrotum. Regional lymph nodes were not enlarged.

Donovanosis and squamous cell carcinoma: The relationship conundrum!

Donovanosis is a rare, chronic and indolent sexually transmitted infection caused by Klebsiella granulomatis. The ulcers in donovanosis rarely undergo malignant transformation, which is usually seen in longstanding ulcers. We present a case of a 32-year-old male who presented with a two-month history of rapidly progressive, large, foul-smelling ulcers over the groin, distal penile shaft and scrotum. Crushed tissue smears from ulcers revealed basophilic intracellular and extracellular Donovan bodies. Fine needle aspiration cytology from inguinal lymph nodes and biopsy from the ulcers revealed well-differentiated squamous cell carcinoma. The current case aims to alert clinicians that donovanosis is a rare but possible cause of cutaneous malignancy. Nonetheless, the pathogenesis of malignant transformation in donovanosis needs further research.

Granuloma inguinale in a 51-year-old man.

Granuloma inguinale, or Donovanosis, is a rare, sexually transmitted ulcerative disease primarily affecting the genital area. In this report, we present a case of a 50-year-old man that was diagnosed with granuloma inguinale after a 2-month history of a penile ulcer. Histological analysis demonstrated the presence of Donovan bodies within macrophages, confirming the diagnosis. He was subsequently treated with trimethoprim/sulfamethoxazole with improvement in the ulcer. This case serves as a reminder to clinicians that although granuloma inguinale is rarely encountered in the US, it should still be suspected in patients with non-healing penile ulcers.

[A case of donovanosis acquired in France]. / Donovanose contractée en France.

INTRODUCTION: Donovanosis (granuloma inguinale) is a bacterial infection caused by Klebsiella granulomatis that occurs mainly in the genital area and is primarily sexually transmitted; it is seen predominantly in the tropics. Herein, we report a case of the disease contracted in metropolitan France. PATIENTS AND METHODS: A 47-year-old man presented with painless ulceration of the glans, present for one month, with progressive extension; there was no history of any recent trip abroad. Skin biopsy with Whartin-Starry and Giemsa staining revealed Donovan bodies in the cytoplasm of macrophages. Based on these findings, further questioning of the patient revealed unprotected sexual contact two months earlier in France. Treatment was initiated with azithromycin 1g on the first day followed by 500mg per day for three weeks. The clinical outcome was spectacular, with almost complete regression of the ulcer at 7 days. DISCUSSION: This case demonstrates that donovanosis can occur in metropolitan France.

2016 European guideline on donovanosis.

Donovanosis is a rare sexually transmitted infection now mainly seen in sporadic cases in Papua New Guinea, South Africa, India, Brazil and Australia. The causative organism is Calymmatobacterium granulomatis, though a proposal has been put forward that the organism be reclassified as Klebsiella granulomatis comb nov The incubation period is approximately 50 days with genital papules developing into ulcers that increase in size. Four types of lesions are described - ulcerogranulomatous, hypertrophic, necrotic and sclerotic. The diagnosis is usually confirmed by microscopic identification of characteristic Donovan bodies on stained tissue smears. More recently, polymerase chain reaction methods have been developed. The recommended treatment is azithromycin 1 g weekly until complete healing is achieved.

Non-healing genital herpes mimicking donovanosis in an immunocompetent man.

Although atypical presentations of herpetic infection in immunocompetent individuals are common, they very rarely have the extensive, chronic and verrucous appearances seen in the immunocompromised host. We report a case of genital herpes manifesting as painless chronic non-healing genital ulcers with exuberant granulation tissue in an immunocompetent man. Owing to this morphology, the ulcers were initially mistaken for donovanosis. To the best of our knowledge, such a presentation of genital herpes in an immunocompetent individual has not been described previously.

Úlcera genital por Klebsiella granulomatis (Donovanosis) en una pareja heterosexual / Genital ulcer due to Klebsiella granulomatis (Donovanosis) in a heterosexual couple

ANTECEDENTES: La Donovanosis o granuloma inguinal, es una enfermedad infecciosa, inflamatoria crónica, usualmente ulcerativa, preferentemente de localización ano-genital, trasmitida sexualmente y causada por la bacteria Klebsiella granulomatis. Se caracteriza por la presencia de los cuerpos de Donovan, en la microscopía de la secreción de las úlceras. El objetivo es presentar un caso de donovanosis en una pareja heterosexual, que consultaron por la presencia simultánea de lesiones en la vulva y en el pene. CASO CLÍNICO: pareja conformada por una mujer de 21 años de edad y su pareja masculina de 24 años, de elevado nivel socioeconómico, que observaron simultáneamente la aparición de una lesión indolora, ulcerada, de bordes elevados y fondo limpio, tanto en el labio mayor de la vulva como en el cuerpo del pene. Negaron la práctica de coito anal o promiscuidad. Se sospechó Donovanosis, por lo cual se realizó extendido citológico de la secreción de la lesión y se encontraron con la tinción de Giemsa, los cuerpos de Donovan en la lesión de la mujer. La muestra tomada al varón fue insuficiente para el estudio. Se realizó manejo de la pareja con doxiciclina. El varón tuvo completa mejoría, pero la mujer por presentar recidiva se le agregó azitromicina. A los cuatro meses del diagnóstico, ambos estaban asintomáticos y con una pequeña área de cicatriz. CONCLUSIÓN: La donovanosis es un cuadro infeccioso que amerita diagnóstico y adecuado tratamiento, ya que tiene potenciales complicaciones genitales e incluso extragenitales, que son consideradas secundarias y pueden llevar a graves afectaciones para la salud.

BACKGROUND: The Donovanosis or granuloma inguinale is an infectious, chronic inflammatory and usually ulcerative disease, preferentially of anogenital location, that is sexually transmitted and caused by the bacteria Klebsiella granulomatis. It is characterized by the presence of the Donovan bodies in the microscopy of the secretion of the ulcers. The objective is to present a case of Donovanosis in a heterosexual couple, who consulted by the simultaneous presence of an injury in the vulva and penis. CASE RECORD: Couple of a 21 year-old woman and a 24 year-old man of high socioeconomic level that observed simultaneously the apparition of a painless and ulcerated injury of elevated edge and clear base, as much in the labia majora of the vulva as in the body of the penis. They denied the practice of anal coitus or promiscuity. The Donovanosis was suspected and the cytological study of the secretion of the injury was carried out. The Donovan bodies were found in the injury of the woman with the Giemsa stain. The sample of the man was insufficient for the study. The treatment of the couple was done with Doxycycline. The man had complete improvement but the woman presented recurrence for what Azithromycin was added to the treatment. To the four months of the diagnosis, both of them were asymptomatic and they had a small area of scar. CONCLUSION: The Donovanosis is an infectious disease that merits diagnosis and appropriate treatment due to it has potential genital and extragenital complications that are considered side effect and could carry to severe alterations for the health.
