2. The HIV/AIDS pandemic is a major public health crisis facing the world todayAn estimated 35.3 (32.2-38.8) million adults and children are living with the virus worldwide (WHO, 2013).Sub-Saharan Africa is one of the regions that is hardest hit by this epidemic; with an estimated 22 (20.5-23.6) adults and children living with this virus in this part of the worldNigeria is one of the countries with highest prevalence rate.INTRODUCTION
3. In Nigeria, it was estimated that 2.9-3.3 million people are living with HIV/AIDS at the end of 2005, with about 220, 000 deaths from AIDS and 930, 00 AIDS infantsIn a similar manner, intestinal parasitic infections are widely distributed throughout the world, especially, in sub-Saharan Africa. In this region, these infections are responsible for 1 million deaths each year.INTRODUCTION…
4. HIV/AIDS significantly weakens the immunity of the body, rendering it susceptible to various opportunistic infections.Lack of safe, portable drinking water, poor hygienic and sanitary conditions are largely responsible for the spread of intestinal parasites in most African countries.Parasites frequently associated with acute and chronic diarrhea in HIV disease include various species of Cryptosporidium spp, Isospora belli, Microsporidia spp, Giardia intestinalis, Entamoeba Cyclospora cayetanensis, Blastocystis, Strongiloides, and Ascaris lumbricoides.Intestinal parasitic infections create a huge concern in the management and care of HIV positive people. INTRODUCTION…
5. Detecting these parasites and understanding the status and significance of the infections they cause will greatly help in proper management and treatment of these patientsInformation on the prevalence of intestinal parasitic infections can help public health bodies to better check further spread within the general populationSuch data underlie the necessity of early diagnosis and management in order to prevent the health complications among HIV/AIDS patientsThis study was conducted to examine prevalence of IPI among HIV/AIDS patients in two health institutions in Abuja, NigeriaINTRODUCTION…
6. It is a cross-sectional study that comprised 119 participants recruited from among the out patients in two health institutions in Nigeria (GEDE AIDS and Infectious Disease Research Institute [GAIDRI], Maitama and the Human virology Institute [HVI]-General Hospital Asokoro-Abuja)The mean age of the participants was 29.2 years, ranging from 1-51 years.The proportion of females and males was 50.4% and 49.6% respectivelyParticipants were briefed on the nature and purpose of the study and participation was voluntary. They were also assured of anonymity for their laboratory testing, after oral consent was obtained from themMETHODOLOGY
7. Samples were collected between October 2005 and March 2006.Two mls of venous blood was collected by a trained phlebotomist from a total of 119 (94 from Asokoro and 25 from Maitama) from consenting participantsAll blood samples were screened for the purpose of HIV antibodies using the Smart Check HIV ½. Reactive samples were confirmed using the western blot assayCD4+ counts were determined manually. Values were enumerated only for those with evidence of HIV infection (n=85)METHODOLOGY…(Sample collection)
8. About 2g of stool samples were collected from all the participants using sterile bottlesThese were examined macroscopically and microscopically for colour, consistency and presence of ova, larvae, trophozoites and cysts of intestinal parasitesAfter centrifugation, fixed smears were examined under the microscope, taking into consideration, the morphological features in identifying different parasitesMETHODOLOGY…(Sample collection )
9. The Ethical Committee of the University of Abuja approved the study design and the research Permission for study was obtained from the GAIDRI-Maitama and HVI-Asokoro Abuja, Nigeria; informed consent obtained from all adults(+18years) study participants.Consent from <18years obtained after permission from parents/guardian-children below 7years had permission of parents or guardiansMETHODOLOGY…(Ethical considerations)
10. Demographic and other data were analysed using Statistical Package for Social Sciences (SPSS version 17.0; Chicago, USA).Significant differences between categorical variables were determined using the independent-samples t-test.p-value of <0.05 was considered statistically significant.METHODOLOGY…(Data analysis)
11. The over all prevalence rate of enteroparasites obtained in this study was 22.7% (27/119)Of HIV sero positive persons, 21/85 (24.7%) had intestinal parasitesIntestinal parasites were also fund in 6/34 (17.6%) of sero negative personsLoose and watery stools were obtained in 21.8% (26/119) RESULTS

15. FINDINGSIntestinal Parasitic Infections have enormous consequences on the health of HIV/AIDs patientsSub-Saharan Africa is already over burdened by HIV infection, and chronic diarrhoea due to intestinal infection is also common in this regionSeveral species of protozoa and other intestinal parasites have been associated with acute and chronic diarrhoea, and even weight loss in HIV/AIDS patients
16. Of HIV sero positive persons, 21/85 (24.7%) had intestinal parasitic infection as well as of 6/34 (17.6%) sero negative individualsHowever, this difference is not statistically significant (p>0.05)Findings…
17. The high prevalent rate of E. histolytica (6.7%) fund in HIV/AIDS in this study agrees with the findings of Udeh et al., (2008) where the highest prevalence obtained for this parasite in Abuja was 36.79%Infection with E. histolytica leads to amoebic dysentery; this explains the presence of diarrhoea among most of the HIV/AIDS persons infected with the parasiteFINDINGS…
18. The higher rate of this parasite in Abuja metropolis may not be unconnected with the geographical location of Abuja, which is in the tropical region. Survival of ova of most intestinal helminthes and cysts of protozoan is favorably guaranteed in the tropical environment FINDINGS…
19. These parasites have been reported among HIV/AIDS patients in Sub-Saharan African countries. In 2008, Mariam et al. found 11.5% of S. stercoralis in HIV/AIDS in EthiopiaStudies have also reported the presence of intestinal parasites in HIV/AIDS patients in other parts of Nigeria (Okodua et al., 2003; Olusegun, Okaka & Machado, 2009; Adesiji et al., 2005).This could be due to poor hygienic and sanitary conditions; and lack of portable drinking water in most communities. Providing portable drinking water, adequate health education on hygienic practices and sanitary facilities for the Nigerian population could help in curbing this problem. FINDINGS…
20. The study highlighted the presence of various intestinal parasites in among HIV-infected patients in NigeriaThe results obtained in this study could provide vital information on various types of intestinal parasites circulating among HIV/AIDS patients in Abuja, hence their relevance in the management of these patients CONCLUSION
