The frequency of intestinal parasites in the samples of Alzahra laboratory of Isfahan (2017-2019)

Parasitic diseases are one of health problems in developing countries. In this study, the frequency of intestinal parasites in Alzahra laboratory of Isfahan province will be evaluated. This study was as descriptive and cross-sectional. A questionnaire was used in it. Finally, the collected data were entered into SPSS version 22 and then were analyzed. Of the 23874 fecal samples studied, 422 samples (1.7%) were positive and 23452 (98.3%) were negative. The highest number of referrals was related to summer. Giardia was the most common parasitic infection in spring, summer and autumn and Blastocystis hominis was the most common parasitic infection in winter. The infection of intestinal parasites should be considered and take more effective steps to increase the level of public and environmental health.

Frequency of Intestinal Parasites in Substance Abusers

This study was conducted to investigate the frequency of intestinal parasites in substance abusers and to reveal its significance. The study was conducted in Van Yüzüncü Yıl University Medical Faculty Parasitology Research Laboratory and University of Health Sciences Turkey Van Training and Research Hospital between May 2019 and February 2020. The patient group included 150 patients with substance abuse who applied to the Alcohol and Drug Addicted Treatment Center of University of Health Sciences Turkey Van Training and Research Hospital, while the control group included 75 patients who had no chronic illness and did not use cigarettes, alcohol, or drugs. Stool samples were examined using native-Lugol and modified acid-fast staining methods. In this study, one or more intestinal parasites were found in 21.3% of 150 patients who applied to the internal medicine outpatient clinic and had no chronic illness and did not use cigarettes, alcohol, or drugs. There was a statistically significant difference between the two groups in terms of the parasite frequency (p=0.03). In the patient group, Giardia intestinalis was detected in 7.3% (p=0.02), Blastocystis hominis in 6.7%, and Hymenolepis nana in 0.7%. Considering the frequency of parasites in terms of age groups, intestinal parasites were found at a higher rate in the 35 and younger age group (23.8%) than in the 36 and older age group (17.2%). Intestinal parasite positivity was found at the highest rate (23.8%) in those using methamphetamine. Constipation (79.3%) was the most prevalent in parasite-positive substance abusers, followed by diarrhea (23%). This study contributed to the literature by determining the frequency of intestinal parasites in people addicted to substance, and it was revealed that intestinal parasite infections are a negative consequence of substance addiction. Conclusively, our findings revealed that intestinal parasites should be considered in substance abusers. Also, more detailed studies involving more individuals should be conducted to obtain information about intestinal parasite infections.

Infection by intestinal parasites in disabled patients and their guardians

Introduction: intestinal parasitic infections are common major problem closely related to poverty, inadequate sanitation, insufficient health care and overcrowding. They cause significant morbidity among institutionalized patients, however, there are few studies that analyze the frequency of intestinal parasites in disabled patients that are not institutionalized. Objective: the aim of the present study was to determine the prevalence of intestinal parasitic infection in disabled patients and their guardians. Methodology: a total of 336 fecal samples were collected from 53 disabled patients and history of diarrhea during the study period and 31 guardians, parents and professional staff of Institution. Parasite research was carried out using zinc sulphate centrifugal-flotation technique, Lutz/Hoffman Pons and Janer method, Rugai method and Gram-Chromotrope, Leishman, Kinyoun, Kato-Katz and Trichrome stains were used. Results: we found 15.5% of positive sample for enteroparasites in all analyzed individuals (13/84), with 11.3% (6/53) of prevalence in disabled patients and 22.5% (7/31) for guardians, with significant difference. There was no difference between gender,but there was a higher number of positives in patients between 6 and 11 years of age. Monoparasitism and the presence of protozoa, especially Blastocystis hominis, were the most prevalent conditions. Conclusions: despite the aforementioned intrinsic susceptibility of patients with special needs, the prevalence of intestinal parasites was low. In guardians, the prevalence was higher, suggesting extreme attention to the care process, which may have prevented the transmission to their disabled patients contact.

Mass Treatment does not reduce the prevalency of parasites in Guarani indigenous schoolchildren in Brazil

The high frequency of intestinal parasites is favored by environmental and socio-cultural conditions of indigenous populations, and is still a neglected public health problem. Mass administration of broad-spectrum drugs aims to reduce the prevalence and intensity of the infections. The prevalence of intestinal parasites in school-children in an indigenous Guarani village in southern Brazil, was evaluated before and after the mass treatment of the population with albendazole. In the first phase of collection of stool samples, 81.4% of them were positive for enteroparasites and in the second phase, after two doses of antiparasitic medication, 87.5% were positive. Although the prevalence of infections by some helminths has reduced after treatment, many parasites remained frequent in the studied population, showing a change in the epidemiological profile in the distribution of these diseases in the population. The prevalence of intestinal parasites in indigenous schoolchildren proved to be high even after mass treatment with albendazole.

Frequency of intestinal parasites in patients attended at a university hospital in Maceió, state of Alagoas, Brazil

The aim of this study was to analyze the parasitological tests of a population at a public hospital in Maceió-AL. A descriptive study was made between January and July of 2015 analyzing the parasitological tests of a population at a public hospital in Maceió-AL. Variables such as gender, age, positive tests, protozoan species, helminths species and parasitic associations were analyzed. Out of 1.581 tests, 806 (51%) tested positive. Regarding gender, 535 (67%) were from women. Helminths were the most predominant infections (63.94%), compared to protozoans (36.06%). The Helminths with the highest number of infections were: Ascaris lumbricoides (93.23%), Trichuris trichiura (2.32%) and Enterobius vermicularis (1.26%). Among protozoans, Endolimax nana and Entamoeba coli corresponded to 78.09% and 15.91% respectively. Although non pathogenic, it suggests fecal contamination. According to the degree of parasitism, 84.0% were monoparasitism. It can be concluded that the number of positive tests for enteroparasites was high, mainly in men. The species A. lumbricoides was the main helminth detected, while E. nana was the main protozoan found in the tests. The age group between 24 and 59 years old was the one that had the highest amount of positive tests. The results observed strengthen the need for the implementation of prevention measures for intestinal parasitic infections.

Frequency of Intestinal Parasites in Patients with Diabetes Mellitus Compared with Healthy Controls in Fasa, Fars Province, Iran, 2018

Background: Parasitic diseases are medically important, especially among immunocompromised patients. Recently, diabetes mellitus (DM) has become one of the most important clinical diseases, and the combination of this disease with parasitic infections can result in serious consequences. Objectives: The aim of this study was to evaluate the infection of intestinal parasites in patients with DM and compare them with healthy individuals in Fasa city and surrounding health centers. Methods: In this case-control study a total of 501 patients and healthy individuals (254 patients with DM and 247 healthy controls) referred to health centers in Fasa, Fars province. Fecal specimens of all of these individuals were collected in a special container. These specimens were investigated using direct smear, concentration method, acid-fast and trichrome staining, agar plate cultivation, and Baermann technique. Results: In this study, 254 diabetic patients (50.7%) and 247 (49.3%) healthy controls were included. The age range of these people was between 25 to 89 years old, with an average age of 57.7 ± 10.7. Our findings revealed that the frequency of intestinal parasites in the control group (18.6%) is higher than the patient group (12.6%). Conclusions: Although the frequency of intestinal parasites in the control group was higher than the patient group, this does not reduce the importance of preventative programs for these patients. Considering the significant effect of unpurified water on intestinal parasites, it is better to consider this issue more in health programs.

Que savons-nous de la limboconjonctivite endémique des tropiques ? Et quel rapport avec les parasites intestinaux ?

We identified 64cases of tropical endemic limbo-conjunctivitis out of 550children seen; a hospital prevalence of 11.6%; thirteen cases (eight boys and five girls) did not meet inclusion criteria, and 51cases were included, 31boys (60.8%) and 20girls (39.2%) with a male/female (M/F) sex-ratio of 1.41. For controls, we included 28males (54.9%) and 23girls (45.1%) for a M/F sex-ratio of 1.22. The prevalence of tropical endemic limbo-conjunctivitis in boys was 12.1%, and for girls it was 7.1% in the case group. Stage II was the most frequent at 29cases (56.9%), as well as the mixed form at 31cases (60.8%). The frequency of intestinal parasites was 14cases (27.5%) in the group of tropical endemic limbo-conjunctivitis patients and 6cases (11.8%) in the control group (P=0.08). Entamoeba histolytica in its cystic form was the most intestinal parasite found in both groups, 10cases for tropical endemic limbo-conjunctivitis (19.6%) and 6cases in the control groups (11.8%). The mean serum IgE among cases was 81.2IU/ml, while in the controls it was 15.6IU/ml (P=0.001) CONCLUSION: There is no relationship between intestinal parasitic infection and the occurrence of tropical endemic limbo-conjunctivitis.

Frequency of Intestinal Parasites Among Sudanese Patients with Irritable Bowel Syndrome

The objective of this case control study is to identify the relationship between intestinal parasitic infection and Irritable Bowel Syndrome (IBS) among Sudanese patients. Method: Two hundred patients diagnosed with irritable bowel syndrome (IBS) and were attended Health Facilities at Khartoum State were enrolled, together with 99 apparently healthy controls. Patients were classified into three groups (IBS-all types, IBS with diarrhea (IBS-D), and IBS with constipation (IBS-C)). Stool specimens were collected form study population and all were subjected to microscopic examination following wet saline preparation, formal-ether concentration technique, Z. N stain, and <i>in vitro</i> cultivation in Locke egg medium. Results: Intestinal parasites were detected in 32% (64/200) of IBS-all types; and in 16.2% (16/99) of control group (P. value 0.005). For patients, 20 (10%) were positive for the Entamoeba cyst, 3 (1.5%) <i>Giardia lamblia</i> cysts, and 41 (20.5%) were positive for <i>Blastocystis hominis</i> cyst. For control, <i>Entamoeba</i> species were detected in 10 (10.1%), <i>G. lambelia</i> one case (1.1%), and <i>B. hominis</i> in 5 (5.2%). <i>Blastocystis hominis</i> was significantly prevalent among IBS-all types than the control group (<i>P. </i> value 0.02). It is more frequent among patients with IBS- D than those with IBS-C (<i>P. </i> value 0.001). Conclusion: This study concluded that, there is a statistical association between presence of intestinal parasites and IBS on study population. <i>Blastocystis hominis</i> was found more frequently detected parasite, and it was found significantly associated with IBS- diarrhea.

Strongyloides stercoralis infection in patients with systemic lupus erythematosus: diagnosis and prevention of severe strongyloidiasis.

Strongyloides stercoralis infection is usually chronic and asymptomatic and may persist undiagnosed for decades. However, in immunocompromised individuals, the infection can cause hyperinfection and dissemination. Therefore, early diagnosis is essential to prevent severe forms of strongyloidiasis. The aims of this study were: (i) to evaluate the frequency of S.stercoralis infection in patients with systemic lupus erythematous (SLE) and (ii) to estimate specific immunoglobulins G (IgG) and E (IgE) production using an enzyme-linked immunosorbent assay (ELISA) method. Seventy-five SLE patients treated with prophylactic anthelmintic therapy were evaluated using the spontaneous sedimentation (SS), Baermann-Moraes (BM) and agar plate culture (APC) methods. Serum anti-S.stercoralis IgG and IgE antibodies were measured by ELISA. Using parasitological methods, the frequency of intestinal parasites was 10.7%, whereas the frequency of S.stercoralis infection was 1.3%. The sensitivity of the ELISA to detect anti-S.stercoralis IgG and IgE was 80% and 76.9%, respectively. Both assays presented the same specificity of 96.7%. The frequency of anti-S.stercoralis IgG and IgE was 16% and 28%, respectively. Six patients were positive for both antibodies. Diagnostic approaches using high-sensitivity parasitological methods and the detection of specific antibodies are essential for the diagnosis of strongyloidiasis in immunocompromised patients. Early detection of infection can alter the course of the disease via appropriate treatment, preventing the occurrence of severe strongyloidiasis.

A survey of intestinal parasites including associated risk factors in humans in Panama

BackgroundIntestinal parasitic infections are among the most common infections worldwide, leading to illness with serious and long lasting implications in children and immunocompromised people. Transmission of intestinal parasites is more frequent in tropical and sub-tropical areas where sanitation is poor and socioeconomic conditions are deficient. Panama is a country where climate and social conditions could be reflected in a high number of people infected with intestinal parasites. The presence, prevalence, and distribution of intestinal parasites in this country have been approached to date only in very restricted areas and population groups, but the impact of intestinal parasite infections at the national level is unknown. Methodology/principal findingsWe conducted a cross-sectional survey between 2008 and 2010 to determine the prevalence of intestinal parasites across Panama. Overall, 14 municipalities in seven provinces of Panama were surveyed. The presence of eggs, cysts, and larvae was assessed by microscopy in 1123 human fecal samples using a concentration technique. A questionnaire to identify risk factors associated with the frequency of intestinal parasites in the study population was also prepared and performed. Overall, 47.4% of human samples presented parasites. Variables including community type, age group, occupation, co-presence of commensals and socioeconomic factors (use of shoes and type of sanitation) were significantly associated with intestinal parasites (p<0.05). Conclusions/significanceThe preliminary data obtained in the current study, showing a high prevalence of fecal–oral transmitted parasites in Panama, place intestinal parasitism as a major health problem in this country. Specific interventions should be planned for the indigenous population, the group most afflicted by intestinal parasites.

Frequency of Intestinal Parasites in Patients With Gastrointestinal Disorders, in Different Parts of Iran During 2012-2013

Background: Intestinal parasites of humans are one of the most important health problems worldwide, especially those located in tropical and subtropical areas. Objectives: The aim of this study was to determine the frequency of intestinal parasites in patients with gastrointestinal disorders, in different parts of Iran. Patients and Methods: A total of 1520 stool samples were collected from patients with gastrointestinal disorders. The stool specimens were examined by direct wet mount, formalin-ether concentration and a modified version of the Ziehl-Neelsen staining technique. Amoeba-positive samples were cultured for further differentiation of Entamoeba histolytica, E. dispar, E. moshkovskii. DNA-based methods were used to differentiate these amoebas and to detect Cryptosporidium- positive samples. Statistical analysis was carried out by SPSS ver. 16. Results: Out of the 1520 individuals studied, 153 (10.06%) were infected at least with one intestinal parasite. 781 (51.4%) of patients were male and 738 (48.6%) were female. The prevalence of protozoan parasites 148 (9.7%) was significantly higher than helminth parasites 5 (0.3%) (P < 0.001). The frequency of intestinal parasites was as follows: Blastocystis sp., 72 (4.73%); Giardia intestinalis, 35 (2.30%); Entamoeba coli 21 (1.38%); Endolimax nana 10 (0.92%); Cryptosporidium spp., 1 (0.06%); Entamoeba dispar, 1 (0.06%); Dientamoeba fragilis, 1 (0.06%); Hymenolepis nana, 3 (0.19%); Dicrocoelium dendriticum, 2 (0.13%). In five (0.32%) of the positive samples, co-infections with two parasites were found. G. intestinalis was more prevalent in male 22/35 (62.86%) than female 13/35 (37.14%) as well as in 0-9 years old group. In one sample Heterodera ova contained larva were seen. Conclusions: Blastocystis and G. intestinalis were the predominant intestinal parasites detected in patient with gastrointestinal disorders. The results indicated that the intestinal parasites, particularly helminth infections have been significantly declined in recent years.
