“…Although E. vermicularis infection commonly presents with perianal pruritus [18], it has also been reported to be associated with chronic abdominal pain, urinary tract infection, salpingitis, eosinophilic ileocolitis and pelvic abscess [19][20][21][22]. Couple of possible hypotheses explained the correlation between E. vermicularis and appendicitis of which mostly suggested ectopic migration of the parasite [23,24]. Occasionally, erratic migration of eggs and larvae can elicit granuloma formation in the appendix [24], kidney [25], peritoneal cavity [26], male urinary tract [27], and female genital tract [28] which may lead to misdiagnosis.…”

Although the main cause of appendicitis is unclear, infection with Enterobius vermicularis is suggested as a neglected risk factor. Since, there is no comprehensive analysis to estimate the prevalence of E. vermicularis in appendicitis; therefore, we conducted a global-scale systematic review and meta-analysis study to estimate the prevalence of E. vermicularis infection in appendicitis cases. PubMed, Scopus, Web of Science and Google Scholar databases were systematically searched for relevant studies published until 15 August 2019. Pooled prevalence of E. vermicularis infection was estimated using the random effects model. Data were classified based on the continents and countries. Moreover, subgroup analyses regarding the gender, the human development index (HDI), and income level of countries were also performed. Fifty-nine studies involving 103195 appendix tissue samples belonging to the individuals of appendicitis were included. The pooled prevalence of E. vermicularis infection was (4%, 95%CI, 2-6%), with the highest prevalence (8%, 95% CI: 0-36%) and lowest prevalence (2%, 95% CI: 1-4%) in Africa and Americas continents, respectively. With respect to countries, the lowest and highest prevalence rates were reported from Venezuela (<1%, 95% CI: 0-1%) and Nigeria (33%, 95% CI: 17-52%), respectively. Indeed, a higher prevalence was observed in females, as well as in countries with lower levels of income and HDI. Our findings indicate the relatively high burden of E. vermicularis infection in appendicitis cases. However, our findings suggest the great need for more epidemiological studies to depth understand overlaps between E. vermicularis infection and appendicitis in countries with lower HDI and income levels.

“…11 Several potential hypotheses have been proposed to elucidate the correlation between E. vermicularis and appendicitis, with the prevailing notion being the ectopic migration of the parasite. 12 Intermittently, the irregular migration of eggs and larvae has the potential to induce the development of granulomas in various anatomical locations, such as the appendix, 12 kidney, 13 peritoneal cavity, 14 male urinary tract, 15 and female genital tract, 16 thereby potentially resulting in diagnostic errors. In the context of appendicitis, the obstruction and inflammation of the appendix can occur as a result of the release and accumulation of eggs from female E. vermicularis.…”

Objective: This study included investigating the quality and prevalence of external and internal (intestinal) parasites among children in various regions at Dhi Qar government. The current study also aimed to focus on and find out the relationship between pinworm infection and appendicitis. Methods: The study was conducted during the period between February and July in the year 2023. The study included 100 patients infected with one or more types of ecto or intestinal parasites of both sexes, their ages ranged from 5 to 12 years. A clinical examination was performed for them by a pediatrician and they were sent to the laboratory to conduct the necessary laboratory tests. Results: The current study revealed that a number of parasitic infections, whether external or internal, are associated with anemia and malnutrition in children, in addition to poor psychological condition. Some cases of parasitic worms, especially pinworms, were associated with acute appendicitis. A number of histopathological changes were found after examining the excised organ histologically These changes included necrosis of the sub mucosal layer, erosion of the mucosal lining, and an abundance of fibroblasts in the muscle and serum layers. Conclusion: Acute appendicitis due to E. vermicularis is a very rare occurrence. The histopathological analysis of resected specimens should pay special attention to search for this parasite for adequate post-operative treatment of patients.

Among numerous theories explaining the possible relations between pinworms and appendicitis, ectopic migration of the parasite stands out as the foremost hypothesis 15 , 16 . Occasionally, erratic migration of eggs, juveniles and adults can provoke granuloma formation in the appendix 16 , kidney 17 , peritoneal cavity 18 , male urinary tract 19 , and female genital tract 20 which may mislead clinicians in the diagnosis and treatment of patients.…”

Background: Although the appendix is the most commonly resected and examined intra-abdominal organ, the pathogenesis and etiology of acute nonspecific appendicitis remain enigmatic. This retrospective study aimed to assess the prevalence of parasitic infection in surgically removed appendices and to evaluate the probable associations between the presence of parasites and the occurrence of appendicitis through parasitological and histopathological examinations of the appendectomy specimens. Materials and methods: This retrospective study was carried out from April 2016 to March 2021 among all patients referred to hospitals affiliated with Shiraz University of Medical Sciences, Fars Province, Iran, for appendectomy. Patient information, including age, sex, year of appendectomy, and type of appendicitis, was collected from the available data in the hospital information system database. In positive cases, all pathology reports were retrospectively evaluated for the presence of the parasite and its type, and analytical and descriptive statistics were carried out using SPSS software version 22. Results: A total of 7628 appendectomy materials were evaluated in the present study. Of the total participants, 4528 (59.4%, 95% CI: 58.2–60.5) were males, and 3100 (40.6%, 95% CI: 39.5–41.8) were females. The mean age of participants was 23.87±14.28 years. Overall, Enterobius vermicularis was observed in 20 appendectomy specimens. Fourteen of these patients (70%) were less than 20 years old. Conclusion: This study indicated that E. vermicularis is one of the common infectious agents that could be found in the appendix and may increase the risk of appendicitis. Therefore, in terms of appendicitis, clinicians, and pathologists must be aware of the possible presence of parasitic agents, especially E. vermicularis, to treat and manage the patients sufficiently.
