Gonococcemia is defined as the presence of Neisseria gonorrhoeae in the bloodstream, which can lead to the development of disseminated gonococcal infection (DGI). Gonorrhea is the second most often reported sexually transmitted disease (STD) in the United States behind chlamydia. About 600,000 people each year in the United States are infected, with only about half being reported.1 Gonococcemia occurs in about 0.5-3% of patients with gonorrhea.
The clinical manifestations of this process are biphasic, with an early bacteremic phase consisting of tenosynovitis, arthralgias,2 and dermatitis, followed by a localized phase consisting of localized septic arthritis. Other potentially severe clinical complications include osteomyelitis, meningitis, endocarditis, adult respiratory distress syndrome (ARDS),3,4 and fatal septic shock.5 Polymyositis is also a rare complication of gonococcemia.
Patients who are pregnant or menstruating may be particularly prone to gonococcemia. Other populations that are at risk of infection include women and those with complement deficiencies, HIV disease, or systemic lupus erythematosus (SLE). DGI is an important, potentially life-threatening, and easily treatable clinical entity that remains the most common cause of acute septic arthritis in young sexually active adults.

Organismal virulence factors, such as pili, aid in adherence of the organism to mucosal surfaces and impede phagocytosis by host macrophages. Outer membrane proteins (ie, proteins 1, 2, and 3) are also involved in determining the virulence of the strain of organism and are used to type the strain (ie, protein 2 is involved in adhesion to host cells). Lipo-oligosaccharides of the organism's cell membrane have marked endotoxic action and are also believed to be related to resistance to serum bacteriocidal action. Additionally, some strains of Neisseria species that are particularly pathogenic produce immunoglobulin A (IgA) proteases that aid in the survival of the organism in mucosal tissues.
Defects in the host's immune defenses are also involved in the pathophysiology, with certain patients more likely to develop bacteremia. Specifically, patients with deficiency in terminal complement components are less able to combat infection, as complement plays an important role in the killing of neisserial organisms. As many as 13% of patients with DGI have a complement deficiency. A study of 22 patients with DGI revealed that total serum complement activity was greater than 25% below the normal mean. Other causes of immunocompromise (eg, HIV, SLE) also predispose to dissemination of infection.
The incidence of DGI naturally parallels the incidence of gonococcal infection. In the United States, the number of gonococcal infections peaked in the 1970s, the era of the sexual revolution. With the onset of the HIV epidemic and the practicing of safe sex techniques, the incidence has dramatically decreased from 468 cases per 100,000 population in 1975 to 100-150 cases per 100,000 population at the turn of the century.
N gonorrhoeae infection, the second most commonly reported notifiable disease in the United States, has incidence rates that have been either declining or stable since 1996. However, in 2005, the national rate (115.6 cases per 100,000 population) increased for the first time since 1999. Further, from 2000-2005, rates in the western United States increased 42%, from 57.2 cases to 81.5 cases per 100,000 population, whereas rates in the 3 other US regions decreased (South, -22%; Northeast, -16%; Midwest, -5%).9
The incidence in developing countries is much greater than that of the United States and Western Europe, where higher levels of education and better access to health care are available. DGI develops in about 0.5-3% of persons with mucosal infection. Azariah and Perkins report increasing prevalence in New Zealand, with the primary risk factors being age younger than 25 years and Māori or Pacific ethnicity.10
DGI is more likely to occur in women because of a higher incidence of occult infection (difficulty in diagnosis) and also because of menstruation and pregnancy.
Gonococcemia remains an important disease in the adolescent and young adult population, with a peak incidence in males aged 20-24 years and females aged 15-19 years. Symptoms and/or diagnosis in young children should raise the issue of potential child abuse.11 Martin et al report on the identification of N gonorrhoeae from a piece of clothing, which was subsequently used to convict a man in the child sexual abuse case .12
History reflects the classic clinical manifestations of gonococcemia — cutaneous lesions, arthritis, and, possibly, pericarditis, discussed in Physical. A dramatic increase in the incidence of gonorrhea has been observed, emphasizing the increasing importance of its complications, particularly in pregnancy.7
The clinical evolution of DGI is biphasic consisting of a bacteremic phase and a localized, suppurative phase.
Risk factors for both mucosal infection and disseminated infection include sexual activity/promiscuity, lower socioeconomic status, ethnic minority, male homosexuality, drug use, lower educational level, and past history of other STDs. See Pathophysiology.

Other causes of arthritis and dermatitis may display a clinical picture similar to that of DGI, with some notable differences.
Reactive arthritis is a human leukocyte antigen B27 (HLA-B27)–associated condition that predominantly occurs in young men and has the clinical triad of urethritis, conjunctivitis, and arthritis. However, the distribution of the arthritis is different, occurring predominantly in the joints of the axial skeleton. The clinical picture is less acute, occurring over the course of weeks rather than days and with less severe fever. This syndrome does not respond to antibiotic therapy, and it does not have the associated dermatitis that occurs in gonococcemia.
Rheumatic fever is a rare illness in the modern era and can present with high fever, rash, arthritis, and endocarditis. This condition follows a streptococcal infection and requires long, emergent intravenous antibiotic therapy for endocarditis; it also responds well to anti-inflammatory medications.
Syphilis, an STD that commonly occurs in sexually active young adults, can also produce a rash, symptoms of arthritis, and genital lesions. However, genital involvement is usually in the form of an ulcer and not urethritis, and the rash can involve the palms and the soles. Laboratory tests, including rapid plasma reagin (RPR) titers, can aid in distinguishing syphilis from gonococcemia.
Nongonococcal septic arthritis can be caused by a variety of organisms, but it presents with an acute onset of joint swelling and pain. Culture of joint fluid commonly reveals organisms. This type of arthritis is a destructive form of arthritis that is usually monoarticular. It most frequently occurs in children and elderly persons. Immediate treatment with antibiotics is indicated.
Other conditions to consider in a patient with arthritis and skin lesions include the following: meningococcemia, hepatitis, bacterial endocarditis, SLE, tenosynovitis (eg, de Quervain disease, infectious), and other seronegative arthritides (eg, ankylosing spondylitis, Sweet syndrome, related dermal vasculitides).
The diagnosis of DGI should be based on clinical findings and confirmed with laboratory investigations if possible.
Histopathologic examination reveals a vasculitislike picture with a perivascular neutrophilic infiltrate and neutrophils containing pustules in the epidermis.
Initial empiric therapy consists of a third-generation cephalosporin, such as ceftriaxone. Once sensitivities are obtained, therapy can be switched to less expensive medications, such as penicillin G or ampicillin. Patients with true penicillin allergies are treated with spectinomycin (spectinomycin not effective against pharyngeal gonococcal infection). The choice of antimicrobial agents for the treatment of gonorrhea is critical in areas where the prevalence of drug resistance is high.19
The Centers for Disease Control and Prevention recommend that all patients with gonorrheal infection are also treated for presumed co-infection with Chlamydia trachomatis. This treatment can be easily accomplished with a tetracycline antibiotic (eg, doxycycline) or a macrolide antibiotic (eg, azithromycin). Current state and Centers for Disease Control and Prevention guidelines should be consulted for the treatment of uncomplicated and disseminated disease. Disseminated disease typically needs more prolonged treatment.20
In April 2007, the Centers for Disease Control and Prevention (CDC) updated treatment guidelines for gonococcal infection and associated conditions.21 Fluoroquinolone antibiotics are no longer recommended to treat gonorrhea in the United States. The recommendation was based on analysis of new data from the CDC's Gonococcal Isolate Surveillance Project (GISP). The data from GISP showed the proportion of gonorrhea cases in heterosexual men that were fluoroquinolone-resistant (QRNG) reached 6.7%, an 11-fold increase from 0.6% in 2001. The data were published in the April 13, 2007, issue of the Morbidity and Mortality Weekly Report. This limits treatment of gonorrhea to drugs in the cephalosporin class (eg, ceftriaxone 125 mg IM once as a single dose). Fluoroquinolones may be an alternative treatment option for disseminated gonococcal infection if antimicrobial susceptibility can be documented.Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of the clinical setting.
