A case of isolated necrotizing cytomegalovirus (CMV) oophoritis disclosed only by necropsy studies in a patient with AIDS, is described. This unusual case report is discussed with a review of the literature dealing with CMV involvement of genital organs in the immunocompromised host, and in patients with HIV infection and AIDS.
Typhoid fever is still a global health problem, mainly in tropical and subtropical areas of the world and in developing countries, where relatively elevated morbidity and mortality rates still are present, mostly because of persisting poor hygienic conditions. In the majority of Mediterranean regions, including Italy, the disease is constantly present, though with a low prevalence rate, as a result of an endemic persistence of Salmonella typhi infection.1-4 On the other hand, in industrialized countries, most cases of S. typhi infection are related to foreign travel or prior residence in endemic countries.4-6 In the United States, 2445 cases of typhoid fever have been reported in the decade 1985 to 1994, and the annual number of cases remained relatively stable over time: over 70% of episodes were acquired in endemic countries (mostly Mexico and India).6 The persisting morbidity of S. typhi also may be supported by the increasing resistance rate of this pathogen against a number of commonly used antimicrobial compounds. For instance, 6% of 331 evaluable S. typhi strains were resistant to ampicillin, chloramphenicol, and cotrimoxazole, and 22% of isolates were resistant to at least one of these three agents in a recent survey performed in the United States.6 The spread of antibiotic resistance among S. typhi isolates is emerging in many countries, and multidrug-resistant strains have been isolated, as well as isolates with poor susceptibility to fluoroquinolones,3-5,7-9 so that in vitro susceptibility should be determined for all cultured strains, and antimicrobial treatment should be adjusted accordingly. Nevertheless, fluoroquinolones (e.g., ciprofloxacin and pefloxacin) or third-generation cephalosporins, still represent the best choice for empirical treatment,2,4,6-8,10 and mortality remains rare in Western countries (less than 1% of episodes), although it is expected to be greater in developing areas of the world. The aim of this report is to describe two cases of typhoid fever that occurred in patients with human immunodeficiency virus (HIV) infection, a rarely reported disease association in industrialized countries.
Peripheral nerve disorders are very common in patients with HIV infection, including inflammatory demyelinating polyneuropathies, such as Guillain-Barré syndrome. Causes of these neuropathies are probably multiple, and often dictated by the stage of the underlying HIV disease. Acute demyelinating polyneuropathy is usually preceded by infections, generally sustained by cytomegalovirus or Campylobacter jejuni, and a co-infection with HIV may represent the initial etiopathogenetic event leading to the neurological disorder. An extraordinary case report of a cytomegalovirus-associated Guillain-Barré syndrome occurred in one of our patients with advanced HIV infection, who was cured by gancyclovir and HAART administration, and gives us the opportunity to briefly discuss the intriguing pathogenetic and clinical correlations among HIV disease, cytomegalovirus infection, this neurological syndrome, and its specific treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
