Disseminated gonococcal infection (DGI) results from bacteremic spread of the sexually transmitted pathogen, Neisseria gonorrhoeae, which can lead to a variety of clinical symptoms and signs, such as tenosynovitis, dermatitis, and multiple skin lesions.
This topic will discuss the epidemiology, clinical manifestations, diagnosis and treatment of DGI. The clinical manifestations, diagnosis and treatment of uncomplicated gonococcal infection (eg, cervicitis and urethritis) are discussed elsewhere. (See "Treatment of uncomplicated gonococcal infections" and "Diagnosis of gonococcal infections" and "Epidemiology, pathogenesis, and clinical manifestations of Neisseria gonorrhoeae infection".)
Disseminated gonococcal infection (DGI) occurs in 0.5 to 3 percent of patients infected with Neisseria gonorrhoeae. Most are younger than 40 years of age, although DGI can occur in virtually any age group.
DGI is a common cause of acute polyarthralgias, polyarthritis, or oligoarthritis in young, healthy patients. Males or females may be affected. As an example, one study of 151 consecutive patients with acute nontraumatic arthritis or arthralgia seen at the University of Washington hospitals found that N. gonorrhoeae was the most common cause of illness . DGI has a number of unique and characteristic clinical features that allow it to be distinguished from other types of infectious arthritis.
PATHOPHYSIOLOGY AND PREDISPOSING FACTORS
The probability that a localized gonococcal infection will spread to joints and other tissues depends upon specific host, microbial, and possibly immune factors.
