What is cryptosporidium?
Cryptosporidium is a living thing (organism) that lives in, or on, another organism (a parasite). It can infect your bowels (intestines) and cause cryptosporidiosis. Cryptosporidiosis is an infection of your bowels (gastroenteritis) which can lead to diarrhoea and sometimes being sick (vomiting). Cryptosporidium is a protozoan parasite. A protozoan is a microscopic, single-celled organism. Cryptosporidium can infect humans, cattle and other animals, particularly farm animals. There are two main species of cryptosporidium that cause infection in humans - Cryptosporidium hominis ( C. hominis) and Cryptosporidium parvum ( C. parvum ).
How do you develop cryptosporidiosis?

Why does my water filter not remove Cryptosporidium?
Filters may not remove Cryptosporidium as well as boiling does because even good brands of filters may sometimes have manufacturing flaws that allow small numbers of Cryptosporidium parasites to get past the filter. Also, poor filter maintenance or failure to replace filter cartridges as recommended by the manufacturer can cause your filter to fail.
What antibiotics are used for cryptosporidiosis?
The earliest trials on the treatment of cryptosporidiosis include the use of macrolide antibiotics in both in vitro and in vivo studies. Azithromycin is one of the macrolide antibiotics widely used in these studies, particularly after being found to inhibit the growth of Cryptosporidium in culture medium and in immunosuppressed rats ( Giacometti et al., 1996; Rehg, 1991 ). Two studies conducted in HIV-infected adults showed 67%–100% clinical improvement with doses ranged from 500 mg to 1.5 g ( Dionisio et al., 1998; Kadappu et al., 2002 ). A larger dose did not seem to contribute much in the abatement of diarrhea episodes and parasite clearance in these studies. In contrast, longer treatment duration using 500 mg dose over 14 days yielded better oocyst reduction up to 83% ( Dionisio et al., 1998; Kadappu et al., 2002 ). Another case report also showed highly efficacious results in children with cancer using the dose of 10 mg/kg on day 1 and 5 mg/kg on days 2 through 10 ( Hicks et al., 1996 ).
What is cryptosporidium parasite?
Cryptosporidium belongs to the Phylum Apicomplexa, which infects a wide range of vertebrate hosts, including humans ( Gerace et al., 2019 ). This intracellular protozoan parasite is generally transmitted through ingestion of food or water contaminated with its oocysts ( Samie et al., 2015 ). Cryptosporidium infects the gastrointestinal epithelium, causing diarrhea that is mostly mild yet sometimes debilitating in certain groups of individuals ( McCann, 2019 ). The first human cases of cryptosporidiosis were noticed in 1976, and the parasite was then recognized as an opportunistic pathogenic parasite associated with diarrhea in immunocompromised individuals ( Meisel et al., 1976; Nime et al., 1976 ). Along with the increasing incidence of human immunodeficiency virus (HIV) infection worldwide in the early 1980s, Cryptosporidium became more widely known as acquired immunodeficiency syndrome (AIDS)-defining disease ( Ahmadpour et al., 2020; Ashigbie et al., 2021 ).
How much nitazoxanide should I take for cryptosporidiosis?
Current review addressed diverse therapeutic modalities that have been used in clinical trials with different results that may be implemented in various settings. Nitazoxanide is the most frequently studied drug for the treatment of human intestinal cryptosporidiosis. Based on current review, a possible recommendation on the use of nitazoxanide will be the age-adjusted dose of 100 mg–500 mg given twice daily for 3 days, preferably in immunocompetent patients of all ages ( Abaza et al., 2016; Amadi et al., 2002; Hussien et al., 2013; Rossignol et al., 2001, 2006 ), whereas in HIV individuals nitazoxanide did not demonstrate superiority than placebo ( Amadi et al., 2009; Rossignol et al., 1998 ). The use of 500 mg of paromomycin, 3 to 4 times daily for a minimum of 14 days showed an exceptional cure rate of cryptosporidiosis, particularly in HIV-infected adults with CD4 >200 cells/uL ( Bissuel et al., 1994; Fichtenbaum et al., 1993 ), and not in severely compromised HIV patients ( Flanigan et al., 1996; Hewitt et al., 2000; Smith et al., 1998; White et al., 1994 ). The efficacy of paromomycin, however, was found to be inferior to nitazoxanide ( Hussien et al., 2013 ). According to the results of the controlled trials included in the current review, the use of macrolide antibiotics showed no effective results in both clinical and parasitological improvement. The use of HBC and BLE was limited to only reducing the severity of diarrhea in immunocompromised patients ( Florén et al., 2006; Greenberg and Cello, 1996; McMeeking et al., 1990; Nord et al., 1990; Plettenberg et al., 1993; Rump et al., 1992 ), and should possibly be administered as a complementary therapeutic drug along with other antimicrobials to reach optimal parasite eradication. Nevertheless, other than the efficacy itself, side effects should also be considered especially when the drugs are to be administered in higher doses or in a longer therapeutic regimen. The availability of drugs must be noted, as some drugs may not be available in less-developed countries. Our review demonstrated a wide variety of therapeutic options for human intestinal cryptosporidiosis. However, the number of patients included in majority of the studies was very small, and the disease spectrum and progression in which the studies were conducted was generally limited. The degree of immune suppression in HIV individuals may also play a role in clinical manifestations and therapeutic responses, as HIV-seropositive individuals with preserved CD4 levels might have had comparable immune response with that of immunocompetent individuals. Additionally, careful interpretation of data should be taken especially on the severity of diarrhea and the number of oocysts prior to any therapeutic modalities to justify the effectiveness of the treatment. This should encourage further large prospective studies in wide range of patients, both immune-competent and -compromised, and asymptomatic individuals.
What databases were used to search for cryptosporidium?
Literature searching was performed using three online databases, including PubMed (MEDLINE), EMBASE, and Google Scholar. Inclusion criteria were published results of clinical trials written in English and related to the treatment of human intestinal cryptosporidiosis. Truncations and Boolean terms were utilized to facilitate literature searching. Combinations of the following search terms were used for article explorations: Cryptosporidium, treatment, drug, trial, random, nitazoxanide, paromomycin, azithromycin, spiramycin, roxithromycin, somatostatin, letrazuril, albendazole, rifaximin, miltefosine, clofazimine, and colostrum. The search yielded a total of 271 articles. After removing duplicates and applying inclusion and exclusion criteria, 42 studies were included in this review ( Fig. 1 ).
Does paromomycin help with cryptosporidiosis?
The efficacy of a non-absorbable aminoglycoside called paromomycin has also been studied in several clinical trials in the treatment of human cryptosporidiosis. Paromomycin inhibits protein synthesis by binding to the prokaryotic ribosomes of Cryptosporidium, hence preventing the infection ( Marshall and Flanigan, 1992 ). In the published studies, all were conducted in individuals with immunocompromised status ( Table 3 ). Some of the studies conducted in HIV-infected individuals with CD4 levels of ≤200 cells/uL resulted in clinical improvement of less than 50% and a low degree of parasite clearance ( Flanigan et al., 1996; Hewitt et al., 2000; Smith et al., 1998; White et al., 1994 ). The 500 mg dose administered 3–4 times daily for 14–21 days did not seem to give a significantly better outcome in this population compared to placebo ( Hewitt et al., 2000; White et al., 1994 ). Higher dose of paromomycin and the addition of azithromycin for longer treatment duration also yielded sub-optimal results ( Smith et al., 1998 ). Nevertheless, there were studies that reported 92–100% clinical improvement along with 75–92% parasite eradication rate after the administration of paromomycin ( Bissuel et al., 1994; Fichtenbaum et al., 1993 ). However, these research did not give detailed characterization on the severity of patients’ immunocompromised status and were conducted in a relatively small population. Another randomized controlled trial (RCT) conducted in children reported inferior cure rate of paromomycin when compared to nitazoxanide (69%–87%) ( Hussien et al., 2013 ). However, the latter study was conducted in immunocompetent children. Other than gastrointestinal upset, an alarming side effect of paromomycin was elevated alkaline phosphatases ( Hewitt et al., 2000 ). Reported clinical trials on the use of paromomycin as the treatment of human cryptosporidiosis remain lacking, possibly due to the consistently low efficacy despite extended therapeutic regimen.
What is cryptosporidiosis?
