What symptoms does microsporidiosis cause?
Although microsporidiosis can occur in people with normal immune systems, it is very uncommon. The symptoms of microsporidiosis primarily occur in people with immune-system deficiency, such as HIV-infected individuals and organ-transplant recipients. Microsporidiosis can cause intestinal, lung, kidney, brain, sinus, muscle, or eye disease.
Intestinal symptoms that are caused by microsporidia infection include chronic diarrhea, wasting, malabsorption, and gallbladder disease. In patients with AIDS, the chronic diarrhea may be extremely debilitating and carries a significant mortality risk. The majority of cases of intestinal microsporidiosis in AIDS patients are caused by Enterocytozoon bieneusi.
Microsporidiosis can cause infection in the urinary tract, kidney failure, bladder inflammation, and bowel perforation. Microsporidia can also spread throughout the body to cause inflammation in the brain, pancreas, sinuses, and muscle tissue.
How is microsporidiosis diagnosed?
There are several tests available to diagnose microsporidia infection. Microscopic examination of stained samples of body fluids, primarily fecal samples, allows for rapid diagnosis, although the exact species of microsporidia may not be identified. Urine samples can also be used to detect spores when the kidney and/or bladder are involved.
A powerful microscope, called a transmission electron microscope, is needed to identify the species of microsporidia. However, this form of testing is expensive, and it is not available for routine use in all laboratories.
Finally, blood tests and imaging studies can also assist in detecting microsporidiosis.
