It may also be a side effect of antibiotics used to treat bacterial causes of diarrhea (common for Clostridioides difficile). In the later stages of HIV infection, diarrhea is thought to be a reflection of changes in the way the intestinal tract absorbs nutrients and may be an important component of HIV-related wasting. [22]
In patients with HIV, infections may be more frequent, may cause prolonged bouts of dirty brown diarrhea, and may be more commonly associated with bacteremia and antibiotic resistance. In participants of unprotected anal intercourse, campylobacteriosis is more localized to the distal end of the colon and may be termed a proctocolitis.
Acquired immunodeficiency syndrome (AIDS) is defined as an HIV infection with either a CD4 + T cell count below 200 cells per μL or the occurrence of specific diseases associated with HIV infection. [32] In the absence of specific treatment, around half of people infected with HIV develop AIDS within ten years. [32]
Campylobacter spp. are a common cause of bacterial diarrhea, but infections by Salmonella spp., Shigella spp. and some strains of Escherichia coli are also a frequent cause. [36] In the elderly, particularly those who have been treated with antibiotics for unrelated infections, a toxin produced by Clostridioides difficile often causes severe ...
Cryptosporidiosis, sometimes informally called crypto, [1] is a parasitic disease caused by Cryptosporidium, a genus of protozoan parasites in the phylum Apicomplexa.It affects the distal small intestine and can affect the respiratory tract in both immunocompetent (i.e., individuals with a normal functioning immune system) and immunocompromised (e.g., persons with HIV/AIDS or autoimmune ...
MAC bacteria should always be considered in a person with HIV infection presenting with diarrhea. [citation needed] The diagnosis requires consistent symptoms with two additional signs: [citation needed] Chest X-ray or CT scan showing evidence of right middle lobe (or left lingular lobe) lung infection
WHO Disease Staging System for HIV Infection and Disease was first produced in 1990 by the World Health Organization [1] and updated in 2007. [2] It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to symptomatic HIV disease .
In the developing world, especially sub-Saharan Africa and Asia, cholera is a common cause of gastroenteritis. This infection is usually transmitted by contaminated water or food. [31] Toxigenic Clostridioides difficile is an important cause of diarrhea that occurs more often in the elderly. [17]
