In two double-blind, controlled trials in pediatric patients with diarrhea and with or without enteric symptoms (e.g., abdominal distention, colic, left iliac fossa tenderness) caused by Cryptosporidium parvum, a three-day course of treatment with nitazoxanide (100 mg BID in pediatric patients ages 12-47 months, 200 mg BID in pediatric patients ages 4 through 11 years) was compared with a placebo. However, it is not effective in severely immunocompromised patients and there is limited data in infants.

Study Design Recommended as drug of choice for treatment of cryptosporidiosis. cryptosporidium. At one month following Nitazoxanide treatment… Nitazoxanide is FDA approved for the treatment of Cryptosporidium … Most studies in immune-competent patients have reported clinical and parasitologic response rates close to 80% and 70%, respectively, for both indications. Studies evaluating the effectiveness of nitazoxanide for the treatment of cryptosporidiosis Two studies [ 28 , 31 ] showed no evidence that paramomycin is more effective in reducing the frequency of diarrhoea than placebo with a summary RR of 0.74 (95% CI 0.42, 1.31) ( Figure 2 ). Designated an orphan drug by FDA for treatment of cryptosporidiosis. Nitazoxanide is approved for the treatment of giardiasis and cryptosporidiosis (first drug approved for the latter indication) in immune-competent children <12 years of age. Treatment of diarrhea caused by Cryptosporidium parvum in immunocompetent adults, adolescents, and children ≥1 year of age. Rossignol JF, Ayoub A, Ayers MS. The lack of effective therapy for cryptosporidiosis remains an immense knowledge gap in the efforts to improve childhood health worldwide. Untreated patients were not assessed in this study; however, it is possible that failure to treat reflects a milder illness and/or a lack of awareness of potential nitazoxanide efficacy by the treating clinician.

For patients with AIDS, highly active antiretroviral therapy and supportive care are used; nitazoxanide may improve symptoms, but does not cure infection in persons with untreated AIDS. Nitazoxanide Vs. Metronidazole | Alinia Drug Studies. A clinical trial comparing nitazoxanide versus placebo in children without HIV infection demonstrated that resolution of diarrhea and parasitologic cure were significantly higher in children treated with nitazoxanide. While initially reported in immunocompromised patients such as AIDS patients, cryptosporidiosis has now been documented as a major cause of childhood diarrhea and an important factor in childhood malnutrition. The purpose of this chapter is to discuss the use of nitazoxanide in the treatment of cryptosporidiosis. Therapeutic Approach Cryptosporidium. A further 7 day course of nitazoxanide at 200mg twice daily was given. BACKGROUND: Treatment of cryptosporidiosis in HIV infected children has proved difficult and unsatisfactory with no drugs having demonstrable efficacy in controlled trials except nitazoxanide. 13. Most studies in immune-competent patients have reported clinical and parasitologic response rates close to 80% and 70%, respectively, for both indications. The treatment of cryptosporidiosis with hyperimmune bovine colostrum (HBC), halofuginone, spiramycin, sulfonamides, triazine derivatives and nitazoxanide are reviewed. Treatment of immunocompetent people, when necessary, is with nitazoxanide. Only 27% of those with Cryptosporidium infection received treatment with nitazoxanide, mostly for persistent diarrhoea. This novel agent has a broad spectrum of activity against many other gastrointestinal pathogens, including bacteria, roundworms, flatworms, and flukes. the treatment of intestinal and pulmonary cryptosporidiosis are now discussed. PIP: The effectiveness of nitazoxanide in the treatment of Cryptosporidium parvum and other intestinal parasitic diseases was assessed in 18 patients hospitalized at Point G. National Hospital in Bamako, Mali, with parasite-related diarrhea, dehydration, and weight loss. Their immune system will usually work to clear the infection. Currently, nitazoxanide is the only proven anti-parasitic treatment for Cryptosporidium infections. It has an unclear mechanism of action but is thought to inhibit electron transport reactions within the microbe. Nitazoxanide, sold under the brand name Alinia among others, is a broad-spectrum antiparasitic and broad-spectrum antiviral medication that is used in medicine for the treatment of various helminthic, protozoal, and viral infections. Nitazoxanide is a thiazolide antimicrobial that reduces the load of parasites and is currently a first-in-class treatment for persistent, severe Cryptosporidiosis in immunocompetent individuals (11–16). When such treatment strengthens the weakened immune system, diarrhea is usually reduced. infections in mammals and no compound is consistently effective. Cryptosporidiosis is increasingly recognized as an important global health concern. Treatment of immunocompetent people, when necessary, is with nitazoxanide. The objective of this study is to see treatment outcomes with 7 days of nitazoxanide in immunocompetent adult patients diagnosed with cryptosporidiosis and to consider combination therapy which includes nitazoxanide with paromomycin or azithromycin? The United States Food and Drug Administration has approved the parasiticidal agent nitazoxanide for treatment of diarrhea caused by Giardia lamblia/intestinalis or Cryptosporidium parvum. Nitazoxanide therapy has not been reported to cause serum aminotransferase elevations during therapy or … Nitazoxanide treatment reduced the duration of both diarrhea (P ! Uses for Nitazoxanide Cryptosporidiosis. Cryptosporidium parvum infection is associated with chronic diarrhea and wasting leading to death in persons with Acquired Immune Deficiency Syndrome (AIDS), and in non- HlV-infected persons, C. parvum infection can cause diarrhea leading to malnutrition, impaired physical and … We hypothesised that a prolonged course of treatment with high dose nitazoxanide would be effective in treating cryptosporidiosis in HIV positive Zambian children. Nitazoxanide Nitazoxanide is a nitrothiazolyl-salicylamide derivative, which was US FDA approved for treatment of cryptosporidiosis and giardiasis in patients who do not have HIV. DATA SYNTHESIS: Nitazoxanide is approved for the treatment of giardiasis and cryptosporidiosis (first drug approved for the latter indication) in immune-competent children <12 years of age. It should be noted that nitazoxanide is the only drug approved by the FDA in humans, as a treatment option for cryptosporidiosis . Currently, nitazoxanide is the only proven anti-parasitic treatment for Cryptosporidium infections. “Nitazoxanide in the treatment of acquired immune deficiency syndrome-related cryptosporidiosis: results of the United States compassionate use program in 365 patients”.
