Item Prevalence of soil-transmitted helminth infections in HIV patients: a systematic review and meta-analysis(Nature Research, 2023-07-08T00:00:00) Akanksha, Kumari; Kumari, Ashu; Dutta, Omprokash; Prasanth, Ajay; Deeba, Farah; Salam, NasirSoil-transmitted Helminth (STH) infections have been found associated with people living with human immunodeficiency virus (HIV) but little is known about the overall burden of STH coinfection in HIV patients. We aimed to assess the burden of STH infections among HIV patients. Relevant databases were systematically searched for studies reporting the prevalence of soil-transmitted helminthic pathogens in HIV patients. Pooled estimates of each helminthic infection were calculated. The odds ratio was also determined as a measure of the association between STH infection and the HIV status of the patients. Sixty-one studies were finally included in the meta-analysis, consisting of 16,203 human subjects from all over the world. The prevalence of Ascaris lumbricoides infection in HIV patients was found to be 8% (95% CI 0.06, 0.09), the prevalence of Trichuris trichiura infection in HIV patients was found to be 5% (95% CI 0.04, 0.06), the prevalence of hookworm infection in HIV patients was found to be 5% (95% CI 0.04, 0.06), and prevalence of Strongyloides stercoralis infection in HIV patients was found to be 5% (95% CI 0.04, 0.05). Countries from Sub-Saharan Africa, Latin America & Caribbean and Asia were identified with the highest burden of STH-HIV coinfection. Our analysis indicated that people living with HIV have a higher chance of developing Strongyloides stercoralis infections and decreased odds of developing hookworm infections. Our findings suggest a moderate level of prevalence of STH infections among people living with HIV. The endemicity of STH infections and HIV status both are partially responsible for the burden of STH-HIV coinfections. � 2023, The Author(s).Item Prevalence of Amoebiasis and Associated Complications in India: A Systematic Review(Springer Science and Business Media Deutschland GmbH, 2022-04-11T00:00:00) Gupta, Palak; Singh, Kiran Kumari; Balodhi, Ashutosh; Jain, Khushi; Deeba, Farah; Salam, NasirPurpose: Intestinal protozoan parasites are responsible for diarrheal diseases causing significant morbidity and mortality. Entamoeba histolytica is the principle protozoan parasite associated with diarrheal infections. The infection is often associated with inaccessibility to clean drinking water and poor sanitary conditions in low- and middle-income countries including India. A comprehensive systematic review was performed to evaluate a reliable nationwide estimate for prevalence and geographic distribution of amoebiasis in India and the complications associated with it. Methods: We used the PRISMA guidelines to perform a systematic review and meta-analysis of articles published between the year 2001�2020. Two English language databases PubMed and Web of Science were searched to achieve relevant studies. Results: Initial searches resulted in 467 studies out of which 64 eligible articles involving data from 289,659 human subjects from 12 states and 4 union territories were included in the final analysis. Prevalence of amoebiasis ranged from 3-23% in asymptomatic population, 0.64�11% in symptomatic patients and 1�17.5% in HIV-infected patients. Highest prevalence was seen in Tamil Nadu, Andaman Nicobar Island and North East India. Extra intestinal invasion of Entamoeba histolytica leading to complications such as amoebic liver abscess, amoebic colitis, colonic perforation and ameboma were also reported. Such complications have the potential to increase healthcare burden and may prove to be fatal. Conclusion: Amoebiasis remains a significant public health issue in India responsible for diarrheal diseases causing significant morbidity and mortality. Entamoeba histolytica is the principle protozoan parasite associated with amoebiasis. Public health efforts should be directed towards its control and better diagnostic methods should be employed for distinguishing between pathogenic and non-pathogenic species of Entamoeba. � 2022, The Author(s) under exclusive licence to Witold Stefa?ski Institute of Parasitology, Polish Academy of Sciences.Item Prevalence of soil-transmitted helminth infections in HIV patients: a systematic review and meta-analysis(Nature Research, 2023-07-08T00:00:00) Akanksha, Kumari; Kumari, Ashu; Dutta, Omprokash; Prasanth, Ajay; Deeba, Farah; Salam, NasirSoil-transmitted Helminth (STH) infections have been found associated with people living with human immunodeficiency virus (HIV) but little is known about the overall burden of STH coinfection in HIV patients.
