Epididymo-orchitis due to brucellosis

Clinical Presentations of Brucellosis Over a Four-Year Period at Sultan Qaboos University Hospital and Armed Forces Hospital, Muscat, Oman

Objectives

Brucellosis is a highly contagious zoonotic disease which can have serious health implications for affected humans and livestock. This study aimed to evaluate the clinical presentation, geographical distribution and risk factors of brucellosis cases admitted over a four-year period to two hospitals in Muscat, Oman.

Methods

This observational study was conducted from January 2015 to December 2018 at the Sultan Qaboos University Hospital and Armed Forces Hospital in Muscat. All patients with probable or definitive diagnoses of brucellosis according to the diagnostic criteria of the World Health Organization were included. Relevant data were gathered from the patients’ medical records, including results from standard agglutination tests, Brucella enzyme-linked immunosorbent assays, bacterial blood or tissue/aspirate cultures and Brucella polymerase chain reaction tests.

Results

A total of 64 patients were diagnosed with brucellosis over the study period. The median age was 31.5 years and 73.4% were male. The majority (95.2%) presented with fever, followed by weight loss (51%), transaminitis (48.4%), peripheral arthritis/arthralgia (15.9%) and back pain (spondylodiscitis/sacroiliitis; 23.4%). Overall, 75.5% reported having consumed raw dairy products, while only 25.9% gave a positive history of animal contact.

Conclusion

Patients with brucellosis presented with a wide range of clinical features, the most predominant of which was fever. The majority of patients were residents of or had recently visited Salalah and had consumed raw dairy products. These findings highlight the need for healthcare practitioners to maintain a high index of suspicion for this diagnosis. Moreover, further regulatory measures are necessary to oversee the sale of raw/unpasteurised dairy products.

Comparison of inflammatory markers between brucella and non-brucella epididymo-orchitis

Objectives:

Brucellosis is a multi-system infectious disease that is associated with inflammation, which causes an increase in acute phase reactants. Hematological inflammatory markers of brucellosis include mean platelet volume (MPV), red cell distribution width (RDW), neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR). In this study, we aimed to evaluate the diagnostic value of hematological inflammatory markers in Brucella epididymo-orchitis (BEO), and to investigate the utility of these markers for differential diagnosis from non-Brucella epididymo-orchitis (non-BEO).

Materials and Methods:

We retrospectively reviewed the records of 22 BEO and 50 non-BEO patients. Hematological parameters were recorded and compared between the two groups. The main diagnostic criteria for BEO were positive clinical findings (i.e., testicular pain, tenderness and scrotal swelling), a positive Rose Bengal test result, standard tube agglutination (STA) titer ≥ 1/160, and/or a positive blood culture.

Results:

The most decisive factors in discriminating between BEO and non-BEO were NLR, RDW, and MPV, in decreasing order of their strength. Regardless of other factors, NLR values < 2.3 significantly increased the odds of BEO (OR=8.080, 95% CI: 1.929-33.843, p=0.004). After adjusting for other factors, RDW values >14.45% significantly increased the odds of BEO (OR=7.020, 95% CI: 1.749-28.176, p=0.006). Independent of the other factors, patients with MPV < 7.65 fL had a 6.336 times higher risk for BEO (95% CI: 1.393 - 28.822, p=0.017).

Conclusion:

Hematological inflammatory markers such as NLR, RDW, and MPV can aid in the differential diagnosis of BEO and non-BEO.

Testicular infection in brucellosis: Report of 34 cases

BACKGROUND/PURPOSE

To present clinical and laboratory features, treatment options, and outcome in patients with brucellar testicular infection and to compare them with analogous in brucellar patients without testicular involvement.

METHODS

Thirty four brucellar patients with testicular infection treated in two general hospitals in the Republic of Macedonia, during the period 1998-2009, were retrospectively analyzed. Their clinical and laboratory characteristics were compared with analogous in 364 male brucellar patients without testicular infection, who were treated at the same hospitals during the same time period.

RESULTS

Brucellar testicular infection was evident in 34 (8.5%) out of 398 male patients with brucellosis. The median age of the patients was 46.5 years. In all patients testicular involvement was presented as an acute form with a median duration of 5 days (range, 2-14 days) prior to diagnosis. Twenty-three of the patients had at least one other simultaneous focal infection. After starting with the treatment testicular infection lasted a median 10 days, range 7-21 days. Brucellar patients with testicular infection when compared with other brucellar patients more frequently manifested fever (97% vs. 61%), concomitant spondylitis (32% vs. 16%), and urinary system involvement (12% vs. 2%). Also, the relapse rate in patients with testicular involvement was significantly higher (24% vs. 9%).

CONCLUSION

In endemic regions brucellosis should be taken into consideration in any patient with testicular infection. Brucellar testicular involvement is usually characterized with a severe acute clinical presentation and a high percentage of relapses which entails the need of timely recognition and proper treatment duration of at least 60 days.

Brucellar epididymo-orchitis: a retrospective multicenter study of 28 cases and review of the literature

OBJECTIVE

To review retrospectively the clinical symptoms, laboratory findings and treatment outcomes of patients with Brucellar epididymo-orchitis.

MATERIAL AND METHOD

Retrospective data of 28 patients with Brucellar epididymo-orchitis who admitted to four medical centers between 2005 and 2013 were retrospectively reviewed. Positive blood culture, positive Rose Bengal test results or high agglutination titres of ≥ 1/160 with the positive clinical and ultrasonographic findings of orchitis were accepted as the main criteria for Brucellar epididymo-orchitis.

RESULTS

The mean patient age was 31 ± 16.9 years. Testicular involvement was on the left side in 16 patients and on the right side in 11 patients, one had bilateral disease. Testicular pain and swelling were the most common symptoms and elevation of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and leucocytosis were the most common laboratory findings. Initial treatment was orchidectomy in six patients due to malignancy suspicion. All but three patients were successfully treated with antibiotic combinations of rifampicin, doxycycline and streptomycin. Two of three treatment resistant patients underwent orchidectomy.

CONCLUSION

Brucellosis is a common cause of epididymo-orchitis in endemic regions. Early diagnosis and treatment is crucial in the management and thus it must be kept in mind in endemic and non-endemic regions.

Epididymoorchitis as the first finding in patients with brucellosis

Purpose. Acute scrotal pain as the first symptom of brucellosis is rarely observed. We aimed to evaluate the data of male patients with brucellosis and epididymoorchitis as the initial diagnosis. Material and Methods. The data of seven patients presented with testicular pain, hyperemia, swelling, and increased fever were reviewed. Concomitant focal diseases as well as clinical, laboratory, and radiological findings were retrospectively evaluated. Results. The mean age of the patients was 22.28 ± 7.78 (16–35) years. All patients presented with scrotal pain, swelling, and increased sweating. Additional findings included fever, asthenia, arthralgia, dysuria, shiver and rash, weight loss, and vomiting in 6, 5, 4, 4, 3, 2, and 1 patient, respectively. In all of 7 patients, the agglutination tests of Rose-Bengal and Wright were positive. Coombs test was positive only in 3 patients. The patients underwent antibiotic and conservative treatment. No relapse was observed following the treatment. Conclusion. In endemic regions, epididymoorchitis caused by brucellosis should be considered in the differential diagnosis of patients presenting with acute scrotal pain. Clinical and serological findings are sufficient for the diagnosis. Conservative management combined with antibiotic therapy is adequate for managing brucellar epididymoorchitis.

First report of orchitis in man caused by Brucella abortus biovar 1 in Ecuador

We present a 44-year-old man from a rural community in northern Ecuador who worked on a cattle farm where he was involved with primary veterinary care, including assistance during births (or calving) and placenta retention and artificial insemination, with minimal precautions. In September of 2009, quite abruptly, he developed asthenia and hypersomnia without any apparent cause or symptoms like fever, chills, or night sweats. On November 14, 2009, he suffered from pain and edema in the right testicle that coincided with pain in the abdomen. Clinical, serological, and bacteriological investigations confirmed the first case of unilateral orchitis in man in Ecuador caused by Brucella abortus biovar 1. Because brucellosis is a neglected disease, special attention should be given to it in the training of medical and veterinary students.

An unusual complication of a common endemic disease: clinical and laboratory aspects of patients with brucella epididymoorchitis in the north of Iran

BACKGROUND

Brucella epididymoorchitis(BEO) is a focal complication of human brucellosis and has been reported in 2-20% of patients with brucellosis. Brucellosis is an endemic disease in Iran. The incidence of the disease in this country is 34 per 100 000 per year.

METHODS

In a retrospective study, we identified 30 cases of Brucella epididymoorchitis in two teaching hospitals in the north of Iran during 1997-2009.

FINDINGS

Epididymoorchitis occurred in 11.1% of male patients with brucellosis. The average age was 25.5 ± 12.43 years. Pain and scrotal swelling (100%) and fever (96.7%) were the most common symptoms. Different treatment regimens were administered including doxycycline plus rifampin (60%), doxycycline plus rifampin plus aminoglycoside for the first two weeks (36.6%) and doxycycline plus cotrimoxazole(3.4%). Ten percent of the patients did not respond to antibiotic therapy and required surgical drainage or orchiectomy.

CONCLUSIONS

In brucellosis endemic areas, clinicians who encounter patients with epididymoorchitis should consider the likelihood of brucellosis. A careful history and physical examination and an immediate laboratory evaluation help to make a correct diagnosis. Generally, classical therapy of brucellosis is adequate for the treatment of epididymoorchitis.

Epididymoorchitis due to brucellosis in central Anatolia, Turkey

Brucellosis may involve many organs and tissues. Epididymoorchitis is a focal genitourinary complication of human brucellosis. In this study, we describe our experience with the diagnosis, treatment, and final outcomes of 17 patients with epididymoorchitis out of 186 male patients with brucellosis between March 1999 and December 2003. The rate of epididymoorchitisdue to brucellosiswas 9.1%. All subjects complained about swollen, painful testicles. The duration of their complaint varied between 1 week and 2 months. Both testis and epididymis were involved in 15 patients and 2 had bilateral involvement. The patients were treated with medical treatment and a complete resolution was achieved in all of them. Patients with Brucella infection occasionally manifest genitourinary complications. Clinicians, especially those serving in endemic areas or serving patients coming from endemic areas, should consider the likelihood of brucellosis as a cause of epididymoorchitis.

A complication of brucellosis: epididymoorchitis

BACKGROUND

Epididymoorchitis is the most frequent genitourinary complication of brucellosis.

METHODS

This prospective study was conducted between February 2001 and January 2004, prospectively. Male patients diagnosed with brucellosis were included in this study and evaluated for testicular involvement.

RESULTS

Epididymoorchitis was detected in 17 out of 134 (12.7%) male patients with brucellosis. Mean age of the patients was 36.9+/-7.1 years. Twelve patients (70.6%) had acute, four patients (23.5%) had subacute, and one patient (5.9%) had chronic brucellosis. The most common symptoms were scrotal pain (94%) and swelling (82%). Eleven patients had unilateral epididymoorchitis, four had unilateral orchitis and two had unilateral epididymitis. A testicular abscess was detected in one patient. Sperm analysis was performed on 14 patients. Five patients had aspermia and eight had oligospermia. Combined antibiotic therapy was started and continued for 6-8 weeks. Orchiectomy was required for two patients and granulomatous orchitis was detected in the resected specimens. Relapse occurred in only one patient. Three patients had permanent oligospermia and one patient had permanent aspermia after the antibiotic therapy. Younger age, high C-reactive protein level and blood culture positivity were statistically significant differences between the patients with and without epididymoorchitis.

CONCLUSIONS

Brucellosis should be considered in the diagnosis of scrotal diseases in endemic areas. A conservative approach is usually adequate for managing brucellar epididymoorchitis. However, infertility problems may develop in these patients. Well-designed further investigations are needed to explain the relationship between brucellar epididymoorchitis and infertility in man.

Orquiepididimitis por brucela

Brucellosis is a cause of human disease, especially in regions whose brucellosis in animals is enzootic. Brucella orchitis is a rare complication of systemic brucellosis (2-14%). Necrotizing orchitis is posible and it must be distinguished from necrotizing involvement arising from other pathogens (TB or Salmonella). Treatment with specific antimicrobial medication helps to avoid unnecessary orchiectomy and prevent infectious disease in the contralateral testis as well as systemic manifestations. We report a case of brucellar epididymo-orchitis presenting as an acute scrotal mass in a 19 years old male who lived in a city. The anamnesis was crucial in the diagnosis of this rare testicular infection. We review the diagnosis and management of this patology.

Endemic brucellar epididymo-orchitis: a 10-year experience

OBJECTIVE

To present epidemiologic, clinical and laboratory features, treatment and outcome of patients suffering from Brucella melitensis-induced epididymo-orchitis, in comparison with cases of nonspecific epididymo-orchitis. Distinction between these two entities is essential, as treatment and outcome are entirely different.

METHODS

In this retrospective study, records of 17 patients serologically diagnosed as suffering from B. melitensis epididymo-orchitis were reviewed in comparison with 141 cases of non-Brucella epididymo-orchitis. All patients presented consecutively at a tertiary hospital in southwestern Greece, from 1991 to 2000. Statistical analysis was performed using the chi-square test.

RESULTS

B. melitensis epididymo-orchitis differed from nonspecific epididymo-orchitis, due to its high occupational risk, seasonal pattern, gradual onset (P<0.01), longer duration, typical undulatory fever (P<0.05), absence of serious leukocytosis (P<0.05) and lower urinary tract symptoms, and relatively minimal local signs of florid inflammation (P<0.01). Oral medication with doxycycline and rifampicin for 6 weeks was effective, and no relapses or serious side effects were recorded during the follow-up period.

CONCLUSIONS

B. melitensis-induced epididymo-orchitis is a recognized clinical problem in endemic regions, requiring early detection and appropriate medication. Clinicians encountering epididymo-orchitis should consider the likelihood of brucellosis and initiate anti-Brucella medication upon clinical diagnosis and not only after serologic confirmation.

Epididymoorchitis due to Brucella mellitensis: a retrospective study of 59 patients

Epididymoorchitis is a focal form of human brucellosis described in 2%-20% of patients with brucellosis. We assessed 59 cases of Brucella epididymoorchitis (BEO) between 1991 and 1999. The median age of patients was 34 years (range, 15-75 years). The onset of symptoms was acute in 46 patients (78%). Scrotal pain and swelling (100% of patients), fever (88%), and sweating (73%) were the most common symptoms. Brucella species was isolated from blood cultures in 41 patients (69%) and from epididymal aspiration in 4 patients. Treatment consisted of a combination of a doxycycline and an aminoglycoside (n=39) or rifampin (n=10); trimethoprim-sulfamethoxazole with rifampin (n=3); or trimethoprim-sulfamethoxazole as monotherapy (n=7). The median duration of therapy was 45 days (range, 21-90 days). The infections of 9 patients (15%) failed to respond to therapy, and 15 patients relapsed (25%). Three patients with necrotizing orchitis whose infections were unresponsive to antibiotics required an orchiectomy. In general, classical brucellosis therapy is adequate for BEO.

Brucellar epididymo-orchitis in Saudi Arabia: a retrospective study of 26 cases and review of the literature

OBJECTIVE

To review the clinical and laboratory features and response to treatment of patients with acute brucellar epididymo-orchitis reporting to a tertiary care hospital in Riyadh, and to compare these with other cases reported previously.

PATIENTS AND METHODS

In this retrospective study, records of all 26 adult patients with brucellosis, who presented with epididymitis or epididymo-orchitis at a tertiary hospital in Riyadh from 1983 to 2000, were reviewed. Positive blood culture or high agglutination titres of > or = 1 : 320 and positive clinical manifestations of brucellosis were the main criteria for diagnosing brucellosis. Among these cases, epididymitis or epididymo-orchitis was diagnosed on the basis of a typical history of gradual onset of scrotal pain and findings of enlarged tender testes and/or epididymis.

RESULTS

Epididymo-orchitis occurred in 1.6% of all patients with brucellosis. Most (58%) were 25--44 years old; approximately 77% of the patients presented with acute symptoms of < 2 weeks' duration. All patients complained of swollen painful testicles. Other presenting symptoms included undulant fever (96%), chills (54%) and arthralgia (23%). Four patients had dysuria and one haematuria. Ten patients gave a positive history of ingestion of raw milk and milk products; one patient had laboratory-acquired brucellosis. Six patients had unilateral epididymo-orchitis (two with features of florid presentation); the remaining 20 had only orchitis (bilateral in two, right in 10 and left in eight). Leucocytosis was present in six patients; 25 had initial agglutination titres of > 1 : 320 and the remaining patient had a positive blood culture. All patients received combined therapy with streptomycin for the first 2 weeks (or oral rifampicin for 6 weeks) with doxycycline or tetracycline for 6 weeks. All showed improvement, fever subsided in 2--5 days and the scrotal enlargement and tenderness regressed. Only one patient had a relapse within one year.

CONCLUSION

In brucellosis-endemic areas, clinicians encountering epididymo-orchitis should consider the likelihood of brucellosis. A careful history, a meticulous physical examination and a rapid laboratory evaluation help in diagnosis. Clinical and serological data are sufficient for diagnosis. Leucocytosis is not an atypical feature of brucellar epididymo-orchitis and so cannot be used for differentiating it from the nonspecific variety. Conservative management with combination antibiotic therapy is adequate for managing brucellar epididymo-orchitis.

[Relapse in brucella orchiepididymitis]

This paper describes a case of systemic brucellosis accompanied by brucellar orchitis that resolved favourably. There was however a relapse at the testicular level inappropriately treated that triggered a new episode of systemic brucellosis.

The correction of congenital penile curvature in young men

OBJECTIVE

To determine the long-term outcome of multiple parallel plication (MPP) used for correcting congenital penile curvature (with normal urethra and corpus spongiosum), a technique which takes account of the greater force of erection in young men (mean arterial pressure approximately 100 mmHg) than in neonates (approximately 60 mmHg).

PATIENTS AND METHODS

All young men who underwent surgical correction of congenital penile curvature using the multiple parallel plication technique between 1992 and 1995 were reviewed, from their charts and by a telephone survey.

RESULTS

Ten patients (mean age 22.3 years, SD 4, range 17-29) were identified, all of whom had been followed for more than one year (mean 2.8, SD 1.3, range 1.2-4.8). All 10 patients reported a preoperative curvature of 60-90 degrees; postoperatively, eight of the 10 patients had a successful outcome, based on self-documentation of a straighter penis (eight) and/or satisfactory intercourse (four). Two of these eight requested follow-up plications to correct a residual curvature of 15 degrees. All patients reported feeling the sutures as a small bump on the dorsal aspect of the penis. In one patient this was considered bothersome, but it did not interfere with intercourse. In one patient the curvature recurred 5 weeks after surgery, following intercourse. Another patient was lost to follow-up and could not be evaluated.

CONCLUSION

The MPP technique has the following advantages; it entails no dissection of the neurovascular bundle or corpus spongiosum of the tunica, avoiding complications (such as impotence and urethral injury) that may occur with manipulation of these structures; it can be performed under local anaesthesia and can be completed within 30 min; suture cut-through is unlikely because the dorsum (12 o'clock position) of the tunica albuginea is the thickest and hence strongest area of the corporal body; and the straightness of the penis can be determined easily because erection is sustained throughout the procedure. The disadvantages of the MPP technique are; several small bumps from the nonabsorbable sutures may be palpable, and the patient needs to be informed of this preoperatively: aspiration and phenylephrine injection may be required to prevent priapism.

Granulomatous epididymal lesion of possible ischemic origin

In a histologic review of adult epididymides obtained at autopsy (both epididymides of 408 men) or during surgery (261 men with testicular or epididymal nontumoral pathology), a peculiar granulomatous lesion was observed in two autopsy specimens (unilateral) and three surgical specimens. The lesion was located in the caput epididymidis and consisted of a zone of necrosis that involved efferent ducts and interstitial connective tissue and was not associated with an acute inflammatory response. Immunohistochemical study with anticytokeratin antibodies showed the presence of some epithelial cells in the damaged efferent ducts. At the periphery of the lesion, where damage was less severe, the efferent ducts only showed partial necrosis of their wall through which the necrotic material was released to the ductal lumen. Inflammatory infiltrates were scanty and consisted of lymphocytes and CD68-positive macrophages. Lymphocytes were mainly located around the necrotic zone or surrounding the adjacent, well-preserved efferent ducts, whereas macrophages formed large clusters in the ductal lumen. In these clusters, cholesterol crystals and giant cells of foreign body type were frequent. Intratubular epithelial regeneration as well as proliferation of small ducts showing epithelial regeneration and numerous spermatozoa in their lumen were observed. Ceroid granulomata, spermatic granulomata, and epidermoid metaplasia of the efferent ducts were observed in some cases. On the basis of the histologic study, the following developmental stages of the lesion are suggested: ischemic necrosis, granulomatous reaction, cicatrization, and sequelae. The term "granulomatous ischemic lesion" is proposed to designate this reactive lesion.
