Enfermedad gonocócica diseminada en pediatría: reporte de caso y revisión de la literatura / Disseminated gonococcal disease in pediatrics: Case report and review of the literature

La propagación vía hematógena de Neisseria gonorrhoeae, patógeno de transmisión sexual, resulta en una enfermedad gonocócica diseminada (EGD), también conocida como síndrome artritis-dermatitis por el desarrollo de lesiones cutáneas, tenosinovitis y artritis. La población que más frecuentemente se ve afetada es la de adultos jóvenes. Describimos el caso de una adolescente que de forma aguda desarrolló lesiones cutáneas, artritis, tenosinovitis y síntomas constitucionales por EGD. La identificación del agente causal fue por cultivo de secreción vaginal y fue tratada con ceftriaxona intravenosa durante 7 días, con recuperación clínica completa. Es importante diferenciar este cuadro clínico de otros tipos de artritis desarrollados en la adolescencia.(AU)

Hematogenous spread of Neisseria gonorrhoeae, a sexually transmitted pathogen, results in disseminated gonococcal disease (DGD), also known as arthritis-dermatitis syndrome, due to the development of skin lesions, tenosynovitis, and arthritis. The most frequently affected population is young adults. We describe the case of an adolescent female who acutely developed skin lesions, arthritis, tenosynovitis, and constitutional symptoms. The causal agent was identified by a culture of vaginal secretion and treated with ceftriaxone for 7 days with complete recovery. It is important to differentiate this clinical picture from other types of arthritis developed in adolescence.(AU)

Disseminated gonococcal disease in pediatrics: Case report and review of the literature.

Gonococcal Infection: Case Report of Bacteremia and Brief Review of a Series of Cases.

Neisseria (N) gonorrhoeae is the microorganism responsible for the second-most reported sexually transmitted disease in the world, commonly infecting mucosal surfaces such as the endocervix, urethra, and pharynx. Gonococcal disease is generally non-symptomatic or pauci-symptomatic, but if untreated, it can progress to a more serious disease with joint, cardiac, or nervous system involvement. Disseminated gonococcal infection occurs in 0.5 to 3% of patients with gonorrhea and can present with purulent arthritis or a combination of dermatitis, tenosynovitis, and migratory polyarthralgia. This article presents the case of a 45-year-old woman examined in the emergency room for fever and acute pain in her right shoulder and knee. A few days later, the patient developed petechiae and vesiculopustular lesions on her right hand. Blood analysis showed elevated inflammation markers, and cultures yielded gram-negative diplococcus identified as N. gonorrhoeae. The patient was successfully treated with ceftriaxone, with complete remission of signs and symptoms of infection. The article then examines a series of 42 cases of gonococcal disease diagnosed in a tertiary hospital, their microbiologic susceptibilities, and the antibiotics chosen to treat them.

Gonococcal pericarditis with tamponade - use of molecular technology to improve diagnosis and management.

We report a case of gonococcal pericarditis, which was unexpected due to its extremely unusual occurrence. A 42-year-old man presented with fever, chest pain, dyspnea, and tachycardia. He was initially stable but rapidly deteriorated, developing pericardial effusion with tamponade requiring a pericardial window. Incompletely decolorized gram stain of the pericardial fluid initially suggested the presence of gram-positive diplococci, which wrongly directed treatment toward possible pneumococcal infection. Because cultures were negative, identification of the causative organism was attempted by molecular and genotyping analysis. These techniques identified Neisseria gonorrhoeae-multi-antigen sequence type 14994 (por 5136/tbpB 33) as the etiology, which has been associated with disseminated gonococcal disease. Real-time polymerase chain reaction showed no evidence of mutations within the N. gonorrhoeae penA gene responsible for causing ceftriaxone resistance. This was crucial in guiding antibiotic treatment, in light of the high prevalence of multi-drug-resistant N. gonorrhoeae. This case highlights the utility of diagnostic molecular techniques in identifying N. gonorrhoeae as the etiology of an exceedingly rare case of pericarditis.

In Vitro Analysis of Matched Isolates from Localized and Disseminated Gonococcal Infections Suggests That Opa Expression Impacts Clinical Outcome.

Gonorrhea is the second most common sexually transmitted infection, which is primarily localized but can be disseminated systemically. The mechanisms by which a localized infection becomes a disseminated infection are unknown. We used five pairs of Neisseria gonorrhoeae isolates from the cervix/urethra (localized) and the blood (disseminated) of patients with disseminated gonococcal infection to examine the mechanisms that confine gonococci to the genital tract or enable them to disseminate to the blood. Multilocus sequence analysis found that the local and disseminated isolates from the same patients were isogenic. When culturing in vitro, disseminated isolates aggregated significantly less and transmigrated across a polarized epithelial monolayer more efficiently than localized isolates. While localized cervical isolates transmigrated across epithelial monolayers inefficiently, those transmigrated bacteria self-aggregated less and transmigrated more than cervical isolates but comparably to disseminating isolates. The local cervical isolates recruited the host receptors of gonococcal Opa proteins carcinoembryonic antigen-related cell adhesion molecules (CEACAMs) on epithelial cells. However, the transmigrated cervical isolate and the disseminated blood isolates recruit CEACAMs significantly less often. Our results collectively suggest that switching off the expression of CEACAM-binding Opa(s), which reduces self-aggregation, promotes gonococcal dissemination.

Abstract: Gonococcal infection is a sexually transmitted infection on the rise in recent decades. The spread of Neisseria gonorrhoeae to the bloodstream causes a disseminated disease, the main clinical manifestations being joint and cutaneous. The clinical case of a young woman presenting with the typical triad is presented. Diagnostic and therapeutic criteria are reviewed.
