Post-COVID-19 cryptosporidiosis: A serious risk or mere association?

Post-COVID-19 conditions encompass a wide range of health problems, including enteritis, but their association with parasitic infections has not yet been investigated. This study analyzed gastrointestinal symptoms, medical histories, fecal Cryptosporidium oocysts, and the history of COVID-19 infection in patients who attended the Faculty of Medicine, Cairo University, from January to July 2021. Fecal biomarkers, including H. pylori, occult blood, fecal calprotectin (FCAL), and TNF-a, were measured, and Cryptosporidium spp. genotypes were molecularly characterized among post-COVID-19 patients using RFLP. Preliminary results from 210 post-COVID-19 patients revealed that group 1 (Cryptosporidiumpositive) (n = 49) and group 2 (Cryptosporidium-negative) (n = 161) showed no significant difference in the prevalence rate of diabetes mellitus (DM). While group 2 was linked to diarrhea, only infections with Cryptosporidium post-COVID-19 were related to chronic diarrhea, vomiting, and weight loss. A total of 220 healthy subjects served as negative controls. Administering azithromycin, hydroxychloroquine, and ivermectin was significantly related to an increased risk of Cryptosporidium infection in group 1, whereas only azithromycin was more frequently recorded in group 2. Antioxidant supplementation insignificantly affected the incidence of cryptosporidiosis. Cryptosporidiosis with a history of COVID-19 was linked to H. pylori infections, increased inflammatory biomarkers (FCAL and TNF-a), and occult blood when compared with group 2. Cryptosporidium genotype 1 was the most commonly occurring subset in individuals with post-COVID-19. The findings demonstrated that aggravating gastrointestinal manifestations, increased fecal biomarkers and anti-COVID-19 therapeutic interventions are significantly related to the existence of Cryptosporidium oocysts in patients with post-COVID-19, indicating the predominance of.

Clinical and microbial characterization of toxigenic Clostridium difficile isolated from antibiotic associated diarrhea in Egypt.

BACKGROUND AND OBJECTIVES: Clostridium difficile infection (CDI) has become a significant healthcare-associated infection throughout the world and is particularly important in developing countries. This study aimed to investigate clinical characterization and risk factors related to toxigenic C. difficile infection in adult and pediatric patients, antimicrobial susceptibility pattern. Also, to evaluate different diagnostic methods for rapid detection of C. difficile associated diarrhea (CDAD) in Egypt. MATERIALS AND METHODS: Stool samples were collected from 95 pediatric patients and 37 adult patients suffering from antibiotic associated diarrhea and were subjected to direct toxin immunoassay and culture on cycloserine/cefoxitin/fructose agar. The presence of tcdA and tcdB genes was tested by PCR. RESULTS: Toxigenic C. difficile was isolated from pediatric and adult patients at a rate of 17.89% (17/95) and 27% (10/37) respectively. The sensitivity and specificity of direct PCR from stool are (100%, 100% and 82.4%, 100%) in adult and pediatric samples respectively. The susceptibility of C. difficile to vancomycin and metronidazole were found to be 66.7% and 48.2% respectively. CONCLUSION: Diabetes mellitus, prior antibiotic treatment, hematological malignancy on chemotherapy, malnutrition, neutropenia and Ryle feeding are risk factors for development of CDAD. Tight restriction of unnecessary antibiotic uses is necessary in our locality. Direct detection of toxin genes in stool by PCR is sensitive and specific method for early detection of C. difficile.

Multidisciplinary biomarkers aggrieve morbidity in schistosomiasis.

BACKGROUND: Biomarkers by definition are measurable molecules that mark the evidence of certain pathological processes. Collaboration of various biomarkers influences morbidity of schsitosomiasis in Egypt. OBJECTIVES: To identify the biomarkers: CRP, IgE, hemoglobin, ferritin, vitamin D, and platelets in terms of relationship with active and chronic schistosomiasis; demographic data, and their interinfluence. STUDY DESIGN: A cross-sectional study. METHODS: Parasitological analysis of stool and urine samples, Indirect Hemagglutination Test, Enzyme linked Immunoassay, Hematology Analyzer, and Statistical Package SPSS (Statistical Package for the Social Sciences) version 25. RESULTS: Out of 400 participants, 25% suffered of schistosomiasis: active S. mansoni infections in 7 cases (1.75%), S. haematobium infections in 6 cases (1.5%), and chronic schistosomiasis infections in 20 cases (5%). Creactive protein (CRP) likewise IgE levels were higher in active S. mansoni and S. haematobium infections when compared with chronic schistosomiasis. IgE levels appeared to affect infection intensity in S. haematobium. Inversely, hemoglobin (Hb) values were low in active schistosomiasis and upgraded in chronic infection (*p<0.05). Ferritin levels varied in active Schistosoma infection and normalized during chronicity. Vitamin D was reduced in active and chronic schistosomiais. Platelet counts were within normal ranges throughout the study groups. Distribution of ferritin, vit D, and platelets was statistically insignificant among Schistosoma infected population. Age affected only hemoglobin, CRP, and IgE biomarkers. CRP and IgE were in direct relationship together and inversely proportional with hemoglobin (*P <0.05). CONCLUSION: Anemia increased proportionally with biomarkers of inflammatory stress (CRP and IgE) in early infections. Meanwhile, Hb and ferritin (iron stores) improved during chronicity. Hypovitaminosis-D associated the entire course of schistosomiasis while platelet counts were not affected.
