Abstract:
Background: Cytomegalovirus (CMV) co-infection with human immunodeficiency virus (HIV) is known to accelerate HIV disease progression. It has the potential of being a killer disease or a silent lifetime companion in HIV patients. There is dearth of information on CMV prevalence among HIV infected children and adolescents in our environment. We therefore conducted this study to determine its sero-prevalence, and risk factors for co-infection among HIV infected children and adolescents on highly active antiretroviral therapy (HAART) in our center.
Method: A descriptive cross sectional study of HIV-infected children and adolescents aged 2 months to 18 years on HAART was conducted over a 6 month period between October 2017 and March 2018 in our health facility. Blood samples of subjects were screened for CMV IgM using commercial test kits. Biodata of subjects, CD4 cell count, and viral load were collected into a designed proforma, and statistical analysis was done with SPSS version 22.0.
Result: A total of 161 HIV-infected children and adolescents were recruited, 103 (64.0%) were males, 83 (51.6%) were between the ages of 5 and <10 years, 113 (70.2%) were from lower socio-economic class, and 138 (85.7%) were on 1st line HAART. Of the 17 (10.6%) subjects positive for CMV IgM, 3 (17.6%) were less than 5 years old, 11 (64.7%) were between the ages of 5-10 years, and none was older than 15 years. Univariate analysis showed significant differences in the mean age, weight, length/height, and systolic blood pressure between CMV IgM positive and negative patients (p<0.05), but no significant difference in gender, socioeconomic class, types of antiretroviral drugs, CD4 cell count, and viral load (p>0.05). Multivariate analysis however did not show any significant difference in age, weight, length/height, and systolic blood pressure. Conclusion: The prevalence of active CMV infections among HIV infected children and adolescents on HAART in our centre is high. Low CD4 cell count and high viral load were not associated with active CMV disease, and no risk factor for co-infection was also identified. Identifying those with primary/active infection will be necessary for possible treatment with anti-herpes drugs before development of reactivated CMV disease.

Contexte: On sait que la co-infection par le cytomégalovirus (CMV) et le virus de l’immunodéficience humaine (VIH) accélère la progression de la maladie. Il a le potentiel d’être une maladie mortelle ou un compagnon
silencieux à vie chez les patients VIH. Il existe peu d’informations sur la prévalence du CMV chez les enfants et les adolescents infectés par le VIH dans notre environnement. Nous avons donc mené cette étude pour déterminer sa séroprévalence et les facteurs de risque de co-infection chez les enfants et les adolescents infectés par le VIH sous traitement antirétroviral hautement actif (HAART) dans notre centre. Méthode: Une étude transversale descriptive des enfants et adolescents infectés par le VIH et âgés de 2 mois à 18 ans sous multithérapie a été menée sur une période de 6 mois entre octobre 2017 et mars 2018 dans notre établissement de santé. Des échantillons de sang de sujets ont été testés pour l’IgM de CMV en utilisant des kits de test commerciaux. Les données biologiques des sujets, le nombre de cellules CD4 et la charge virale ont été recueillis dans un formulaire conçu à cet effet et une analyse statistique a été réalisée avec SPSS version 22.0. Résultat: 161 enfants et adolescents infectés par le VIH ont été recrutés, dont 103 (64,0%) étaient des hommes, 83 (51,6%) étaient âgés de 5 à moins de 10 ans, 113 (70,2%) étaient issus de milieux socio-économiques inférieurs. et 138 (85,7%) suivaient la multithérapie de première ligne. Sur les 17 (10,6%) sujets positifs pour l’IgM du CMV, 3 (17,6%) avaient moins de 5 ans, 11 (64,7%) étaient âgés de 5 à 10 ans et aucun n’avait plus de 15 ans. Une analyse univariée a montré des différences significatives dans l’âge moyen, le poids, la taille / taille et la pression artérielle systolique entre les patients positifs et négatifs pour IgM anti-CMV (p<0,05), mais aucune différence significative entre le sexe, la classe socio-économique, les types de médicaments antirétroviraux et les cellules CD4 nombre et charge virale (p>0,05). L’analyse multivariée n’a cependant montré aucune différence significative d’âge, de poids, de taille / taille et de pression artérielle systolique. Conclusion: La prévalence des infections à CMV actives chez les enfants et les adolescents infectés par le VIH sous HAART dans notre centre est élevée. Un faible nombre de cellules CD4 et une charge virale élevée n’étaient pas associés à la maladie à CMV active et aucun facteur de risque de co-infection n’a également été identifié. Identifier les personnes présentant une infection primaire / active sera nécessaire pour un traitement éventuel avec des médicaments anti-herpès avant le développement d’une maladie à CMV réactivée.

Abstract:

Background: Urinary tract infection (UTI) remains the second commonest opportunistic infections among HIV infected children. This study was conducted to determine the prevalence and causative bacteria of UTI in HIV infected children and adolescents on antiretroviral medications in our health institution. Method: The study was a cross sectional design conducted between October 2017 and March 2018 among HIV infected children and adolescents aged 2 months to 18 years on follow up attendance at the Paediatric Outpatient Special Treatment Clinic (POSTC) of University of Abuja Teaching Hospital (UATH). Early morning midstream urine was collected from each participant for urinalysis, microscopy and aerobic bacterial culture. Bacteria were identified from culture by standard microbiological methods and antibiogram of the isolates was determined by the disk diffusion method. Result: Of 166 HIV infected children and adolescents studied, 106 (63.9%) were males, 82 (49.4%) were in age group 5-10 years, and 110 (66.3%) were from lower socio-economic class. Significant bacteria (UTI) were isolated in 54 (32.5%) subjects, with 38 (70.4%) from females, and 51 (94.4%) from those on first line antiretroviral therapy. Isolates recovered were Escherichia coli 20 (37.0%), Klebsiella pneumoniae 16 (29.6%), Staphylococcus aureus 8 (14.8%), Pseudomonas aeruginosa 6 (11.1%), and Proteus mirabilis 4 (7.4%). Leucocyturia in 19 (35.2%), nitrituria in 10 (18.5%), and haematuria in 15 (27.8%) subjects with significant bacteriuria were also recorded. Isolates were sensitive to ofloxacin (81.5%), nalidixic acid (74.1%) and cefuroxime (61.1%), while they were resistant to cotrimoxazole (100%), ampicillin (98.1%) and piperacillin (94.4%). Significant difference was observed in the mean CD4 cell count and viral load of subjects with significant bacteriuria compared to those without; 838.6 ± 177.8 versus 1009.9 ± 234.7 cells/μL (p=0.02), and 10, 360.5 ± 471.0 versus 5, 840.8 ± 563.8 copies/ml (p=0.003) for CD4 cell count and viral load respectively. Conclusion: This study reported a high prevalence of UTI among HIV infected children and adolescents, especially in those with high viral load. Routine screening for UTI should be offered to HIV infected children and adolescents with high viral load.

Contexte: L’infection des voies urinaires (UTI) reste la deuxième infection opportuniste la plus répandue chez les enfants infectés par le VIH. Cette étude a été menée pour déterminer la prévalence et la bactérie causale des infections urinaires chez les enfants et les adolescents infectés par le VIH prenant des antirétroviraux dans notre établissement de santé. Méthode: L’étude était une conception transversale menée entre octobre 2017 et mars 2018 chez des enfants et des adolescents infectés par le VIH âgés de 2 mois à 18 ans et suivis à la Clinique de traitement spécial pour enfants ambulatoires (POSTC) de l’Hôpital universitaire de Abuja (UATH) ). Des échantillons d’urine, de microscopie et de cultures bactériennes aérobies ont été recueillis chez chaque participant. Les bactéries ont été identifiées à partir de cultures par des méthodes microbiologiques standard et l’antibiogramme des isolats a été déterminé par la méthode de diffusion sur disque. Résultat: Sur 166 enfants et adolescents infectés par le VIH étudiés, 106 (63,9%) étaient des hommes, 82 (49,4%) étaient âgés de 5 à 10 ans et 110 (66,3%) appartenaient à la classe socio-économique inférieure. Des bactéries significatives (UTI) ont été isolées chez 54 sujets (32,5%), dont 38 (70,4%) de femmes et 51 (94,4%) de celles sous traitement antirétroviral de première intention. Les isolats récupérés étaient Escherichia coli 20 (37,0%), Klebsiella pneumoniae 16 (29,6%), Staphylococcus aureus 8 (14,8%), Pseudomonas aeruginosa 6 (11,1%) et Proteus mirabilis 4 (7,4%). Une leucocyturie chez 19 sujets (35,2%), une nitriturie chez 10 (18,5%) et une hématurie chez 15 sujets (27,8%) présentant une bactériurie importante ont également été enregistrés. Les isolats étaient sensibles à l’ofloxacine (81,5%), à l’acide nalidixique (74,1%) et au céfuroxime (61,1%), tandis qu’ils étaient résistants au cotrimoxazole (100%), à l’ampicilline (98,1%) et à la pipéracilline (94,4%). Une différence significative a été observée entre le nombre moyen de cellules CD4 et la charge virale des sujets présentant une bactériurie significative par rapport à ceux ne présentant pas; 838,6 ± 177,8 par rapport à 1009,9 ± 234,7 cellules/μL (p = 0,02) et 10, 360,5 ± 471,0 par rapport à 5 840,8 ± 563,8 copies/ml (p = 0,003) pour le nombre de cellules CD4 et la charge virale, respectivement. Conclusion: Cette étude a révélé une prévalence élevée d’UTI chez les enfants et les adolescents infectés par le VIH, en particulier chez ceux ayant une charge virale élevée. Un dépistage systématique des infections urinaires doit être proposé aux enfants et aux adolescents à charge virale élevée infectés par le VIH

Abstract:
Background: Human immunodeficiency virus (HIV) and the associated acquired immune deficiency syndrome (AIDS) have remained a serious scourge and a major public health concern, affecting millions in sub-Saharan Africa despite awareness campaigns, preventive measures and promotion of antiretroviral regimens. This study determined the prevalence of HIV among newly admitted students of Ebonyi State University as a measure of the impact of awareness campaign towards prevention of HIV transmission.
Methods: Newly admitted students of Ebonyi State University totalling 2,736 who voluntarily enrolled for the study were screened for HIV infection using the national HIV testing algorithm after information relating to their personal lifestyle, knowledge of safer sex and preventive measures have been obtained with the use of a client intake form.
Results: Of the 2,736 subjects screened, 6 were positive for HIV, giving a prevalence rate of 0.22%, with prevalence rate of 0.29% (4 of 1344) in females and 0.14% (2 of 1392) in males (X2=0.2041, p=0.6514). The positive subjects were spread across age groups 15-19 years (1), 20-24 years (4) and 25-29 years (1). Males and females who have had sex were 801 and 579 out of which 239 and 209 respectively acknowledged to have had unprotected sex within three months of the study.
Conclusion: The low HIV prevalence rate of 0.22% among school age and young adults in this study may indicate that awareness and safe sex campaigns in Ebonyi State have positive impact in HIV prevention amongst these groups of people.

Abstract

The emergence of HIV has reawakened the tuberculosis (TB) scourge and infected patients are prone to opportunistic infections, this study was carried out to determine the HIV status and etiologic agents of Lower respiratory tract infections (LRTI) among tuberculosis suspected patients in Benin City, Nigeria. The study was cross sectional. A total of 276 patients attending tuberculosis clinic were recruited. Questionnaires were filled for each patient. Blood and sputum specimens were collected in plain and sterile containers respectively and transported immediately to the laboratory. Blood samples were screened for the presence of HIV antibodies. The sputum specimens were then cultured following standard microbiological procedure, and thereafter processed using the GeneXpert MTB/RIF assay. Emergent bacterial colonies were identified and susceptibility testing was carried out following standard microbiological techniques. A total of 118 (42.8%) non-mycobacterial bacterial agents were recovered from the patients. Patients were more likely to be culture positive for LRTI in comparison with TB infection (p < 0.0001). There was no association between TB and HIV status (OR = 0.6161, 95%CI = 0.226, 1.648, p = 0.4474). HIV positive patients were more likely to be culture positive for bacterial agents and Klebsiella pneumoniae was more likely to be recovered (p = 0.0338). The fluoroquinolones, gentamicin and ceftriaxone-sulbactam were the most active antibacterial agents against bacterial isolates. The prevalence of LRTI in this study was 52.2%. The study draws attention on the need for physicians to request for bacteriological culture (non-mycobacterial) alongside the TB diagnostic algorithm in suspected TB cases.

V.U. Nwadike, C.G. Anaedobe, R.A. Azeez, S.S. Jinadu, J.O. Chigozie

 

Abstract

Herpes Simplex Virus type 2 (HSV-2) is the leading cause of Genital Ulcer Disease (GUD) worldwide. In HIV infected persons, it typically presents with increased number of recurrent genital lesions which often have severe and prolonged presentations. There are reports that patients receiving highly active antiretroviral therapy (HAART) may be more prone to chronic genital ulcers and a higher risk of acyclovir-resistant herpes infection than is seen in immune competent patients. We present a case of recurrent genital herpes infection in a sexually active 15 year old known HIV patient.

Abstract

Examination of haematological profile is useful for baseline assessment, treatment monitoring and prognostic evaluation in Hiv/AIDS management. The objectives of the study was to assess the haematological profile of HIV seropositive HAART naive patients who attended Kogi State University Teaching Hospital, Anyigba, Kogi State, Nigeria between January 1, 2014 and December 31, 2014. The study was prospective experimental research. Ethical clearance was obtained from ethical committee of Kogi State University Teaching Hospital, Anyigba. Written and verbal informed consent was taken from all patients. A total of 404 HIV seropositive HAART naive patients comprising 147 (36.4%) males and 257(63.6%)females were examined. The overall mean age of patients was 33.0 ±12.7 years and female-male ratio was 1.7: 1. Half of respondents 200(50.4%) accessed HIV care and treatment for the time in stage three HIV disease. Patients had overall mean CD4 cells count of 381.8 ± 240.8 cells/mm3 , white blood cells count of 5.8 ± 3.6 × 109/L, lymphocyte count 2.3 ±1.3, granulocyte count 0.8 ± 0.8 and platelet count of 260.0 ± 109.1 × 109/L. The mean packed cell volume was 34.1± 5.9 %, haemoglobin 11.3 ± 2.1 g/dl and mean corpuscular haemoglobin concentration was 31.5 ± 14.3 g/dl. The packed cells volume (p=0.0001, T test= 4.0259) and haemoglobin (p=0.0001, T test= 4.1534) profiles of HIV clients were respectively statistically significance with gender, while CD4 cells count ( p=0.004, F= 4.523) and platelet count (p= 0.008, F = 3.974) were significance respectively with HIV disease staging. The study recommended the need for awareness programs, nutritional education and micronutrients supplementation including multivitamins for HIV clients.

Abstract

Background: Diseases caused by opportunistic pathogens are the major clinical signs of HIV infected and AIDS patients with parasitic infection being part of the common causes of morbidity and mortality.

Objectives: This was a cross-sectional study to determine the sero prevalence of serum antibodies to three parasitic infections namely Entamoeba histolytica, Schistosoma sp. and Toxoplasma gondii, which are opportunistic infections among HIV/AIDS patients.

Methods: One thousand and eighty patients that attended three healthcare institutions in Lagos were recruited for the study through convenience sampling method. Venous blood was collected from the recruited patients and screened for HIV infection as well as the presence of serum antibodies to three parasitic infections. All positive sera samples were confirmed for HIV infection.

Result: The results revealed that 65/1080 (6%) of the recruited patients were HIV sero-positive. In addition, 5/65 (7.7%) of the HIV positive patients had E. histolytica co-infection, 1/65 (1.5%) had Schistosoma sp. co-infection while 2/65 (3.1%) had T. gondii co infection. The results also indicated that the proportion of patients with E. histolytica was significantly higher among HIV sero-positive patients than the sero-negative patients (P = 0.031).

Conclusion: The study showed the opportunistic potential of the three parasitic infections among HIV/AIDS patients in the study area.

Prevalence of HIV/Sputum AFB positivity among patients attending University of Benin Teaching Hospital (UBTH), Benin City, Nigeria

O Iyoha, WO Osarogiagbon

 

Abstract

Human Immunodeficiency Virus (HIV) and Tuberculosis(TB) have synergistic interactions that speedily accelerate decline of the host’s immune system and accentuate the progression of each other. Eight hundred and ninety five patients referred from different units of University of Benin Teaching Hospital, Nigeria were screened for antibodies to HIV-1 and HIV-2 using ELISA and sputum microscopy for acid-fast bacilli. The result showed that, 92(10.3%) were HIV positive with females 68(14.2%) higher than males 24(5.8%) though not statistically significant (p=0.066), 123(13.7%) patients were AFB positive, with males 75(18.1%) significantly higher than females 48(10%) (p=0.046) and 14(1.6%) patients were co-infected. Although the co-infection rate was higher among females 9(1.9%) than males 5(1.2%), there was no significant difference (p=0.450). The age group 40-49 and 50-59 had the highest TB/HIV co-infection (2.5% each).Regular screening for TB in HIV patients and HIV in TB patients would demonstrate the true burden of TB disease amongst HIV infected patients.

Le virus de l’immunodéficience humaine(VIH) et la tuberculose (TB) ont des interactions synergiques qui rapidement accélèrent le déclin du système immunitaire de l’hôte et accentuent la progression de l’un l’autre. Huit cent quatre – vingt quinze patients des différentes unités de l’université hôpital  d’enseignement de Benin, Nigeria, ont été criblés pour les anticorps a VIH – 1 et VIH – 2 en utilisant ELISA microscopique des expectorations pour les bacilles acide – Résistant. Le résultat a montrée que 92 (10,3%) étaient séropositifs avec des femelles 68(14,2%) plus élevé que les males 24(5,8%), mais pas
statiquement significatif, (p=0,066), 123(13,7%) patients étaient AFB positif, avec les males 75(18,1%) significativement plus élevés que les femelles 48 (10%) (p=0,046) et 14 (1,6%) patients ont été Co – infectés. Bien que le taux de la Co – infection était plus élevé parmi les femelles 9(1,9%) que les males 5 (1,2%), il n y avait pas de différence significative (p=0,450). Le groupe d’âges 40 – 49 et 50 – 59 avait la plus forte Co – infection de TB/HIV (2,5%). Le dépistage régulier de la tuberculose chez les patients VIH et VIH chez les patients tuberculeux démontrerait le véritable fardeau de la maladie de la tuberculose chez les patients infectés par le VIH.

Abstract

Genetic diversity is the hallmark of HIV-1 infection. It differs among geographical regions throughout the world. This study was undertaken to identify the predominant HIV-1 subtypes among infected female sex workers (FSWs) in Nigeria. Methods: Two hundred and fifty FSWs from brothels in Ibadan Nigeria were screened for HIV antibody using ELISA. All reactive samples were further tested by the Western Blot Techniques. Peripheral Blood Mononuclear Cells (PBMCs) were separated from the blood samples of each subject. Fragments of HIV Proviral DNA was amplified and genetic subtypes of HIV-1 was determined by direct sequencing of the env and gag genes of the viral genome followed by phylogenetic analysis . Results: The age of the FSWs ranged from 15 to 55 years old (Mean = 25.8years, SD =3.74). Majority were Nigerians while others (1.6 %) were from neighboring West Africa countries. Four ( 1.6% ) of the FSWs were active for less than one year as sex workers, and the mean length of sex work was 2.80 years ( Range = 1.0 – 15.0 years ). Sixty-four (25.6%) of the 250 CSWs were positive for HIV-1 while 7 (2-8%) had dual infections to HIV-1 / HIV-2. Among the 34 HIV-1 strains  characterized by sequencing, 19 (55-9%) were subtype G, 9 (26.5%) CRF02_A/G, 3 (8.8%) CRF06_cpx while 1 (2.9%) each were identified as subtype C, CRF01_A/E and CRF09_cpx respectively. Nineteen (55.9%) of the FSWs with subtype G had been active in the sex work for between one to five years. The youngest of the HIV -1 infected FSWs with sexual activity of less than a year had subtype G strain. There is a significant probability that infection with this subtype occurred with a short incubation period (p< 0.05). Conclusion: This study showed a wide range of HIV- 1 subtypes among FSWs in Nigeria. The situation poses serious challenge for the design of HIV vaccine candidate for use in Nigeria.

Abstract

Background: Molluscum contagiosum (MC) infection is caused by a pox virus and the virus is probably passed on by direct skinto- skin contact which may affect any part of the body. There is anecdotal evidence associating facial lesions with HIV-related immunodeficiency. This study was aimed to determine the prevalence and associated risk factors of Molluscum contagiosum infection among PLWHAs attending ART clinic at the University College Hospital, Ibadan, Nigeria.

Methods: This is a descriptive cross-sectional survey of 5,207 patients (3519 female and 1688 males) attending ART clinic between January 2006 and December 2007. Physicians performed complete physical and pelvic examinations. Diagnosis of Molluscum Contagiosum infection was based on the clinical findings of typical lesions on the external genitalia, perianal, trunk, abdominal and facial regions.

Results: The mean age of the patients was 34.67 yrs. ± 9.16). About 10% (542) had various sexually transmitted infections (STIs). The male to female ratio was 1: 4.2. One hundred and twenty seven subjects (23.4%) had no formal or primary education with 247 (45.6 %) beingtreatment naïve while 295 (54.4 %) were treatment experienced. Of the 542 PLWHAs with STIs, 3.3 % had undetectable viral load (< 200 copies/ ml) while 272 (50.1 %) had low CD4 count (< 200 cells / mm3.) and The Mean log10 viral load was 5.02 + 0.94. Molluscum Contagiosum infection was diagnosed in 13 patients (0.024%; 8 females and 5 males). Vaginal Candidiasis was the commonest genital infection diagnosed in 223 (41.1%) of the patients with STIs. MC patients had higher viral load, lower CD4 count and more likely to be treatment experienced”.

Conclusions: Molluscum Contagiosum infection is not uncommon among the HIV-infected patients, but underreported. Awareness of this cutaneous manifestation should be known to Physicians in AIDS care.
