RESUMO

BACKGROUND: Uganda has approximately 1.2 million people aged 15-64 years living with human immunodeficiency virus (HIV). Previous studies have shown a higher prevalence of premalignant cervical lesions among HIV-positive women than among HIV-negative women. Additionally, HIV-infected women are more likely to have human papilloma virus (HPV) infection progress to cancer than women not infected with HIV. We determined the prevalence of premalignant cervical lesions and their association with HIV infection among women attending a cervical cancer screening clinic at Mbarara Regional Referral Hospital (MRRH) in southwestern Uganda. METHODS: We conducted a comparative cross-sectional study of 210 women aged 22-65 years living with HIV and 210 women not living with HIV who were systematically enrolled from March 2022 to May 2022. Participants were subjected to a structured interviewer-administered questionnaire to obtain their demographic and clinical data. Additionally, Papanicolaou smears were obtained for microscopy to observe premalignant cervical lesions. Multivariate logistic regression was performed to determine the association between HIV status and premalignant cervical lesions. RESULTS: The overall prevalence of premalignant cervical lesions in the study population was 17% (n = 72; 95% C.I: 14.1-21.4), with 23% (n = 47; 95% C.I: 17.8-29.5) in women living with HIV and 12% (n = 25; 95% C.I: 8.2-17.1) in women not living with HIV (p < 0.003). The most common premalignant cervical lesions identified were low-grade squamous intraepithelial lesions (LSIL) in both women living with HIV (74.5%; n = 35) and women not living with HIV (80%; n = 20). HIV infection was significantly associated with premalignant lesions (aOR: 2.37, 95% CI: 1.27-4.42; p = 0.007). CONCLUSION: Premalignant cervical lesions, particularly LSILs, were more common in HIV-positive women than in HIV-negative women, highlighting the need to strengthen the integration of cervical cancer prevention strategies into HIV care programs.

RESUMO

The activities of HIV-1 in the central nervous system (CNS) are responsible for a dysregulated neuroinflammatory response and the subsequent development of HIV-associated neurocognitive disorders (HAND). The use of post-mortem human brain tissue is pivotal for studying the neuroimmune mechanisms of CNS HIV infection. To date, numerous studies have investigated HIV-1-induced neuroinflammation in post-mortem brain tissue. However, from the commonly investigated studies in this line of research, it is not clear which neuroinflammatory markers are consistently associated with HIV neurocognitive impairment (NCI) and neuropathology (i.e., HIV-encephalitis, HIVE). Therefore, we conducted a systematic review of the association between neuroinflammation and NCI/HIVE from studies investigating post-mortem brain tissue. Our aim was to synthesise the published data to date to provide commentary on the most noteworthy markers that are associated with NCI/HIVE. PubMed, Scopus, and Web of Science databases were searched using a search protocol designed specifically for this study. Sixty-one studies were included that investigated the levels of inflammatory markers based on their gene and protein expression in association with NCI/HIVE. The findings revealed that the (1) transcript expressions of IL-1ß and TNF-α were consistently associated with NCI/HIVE, whereas CCL2 and IL-6 were commonly not associated with NCI/HIVE, (2) protein expressions of CD14, CD16, CD68, Iba-1, IL-1ß and TNF-α were consistently associated with NCI/HIVE, while CD45, GFAP, HLA-DR, IL-1 and IL-6 were commonly not associated with NCI/HIVE, and (3) gene and protein expressions of CNS IL-1ß and TNF-α were consistently associated with NCI/HIVE, while IL-6 was consistently not associated with NCI/HIVE. These markers highlight the commonly investigated markers in this line of research and elucidates the neuroinflammatory mechanisms in the HIV-1 brain that are involved in the pathophysiology of NCI/HIVE. These markers and related pathways should be investigated for the development of improved diagnostics, prognostics, and therapeutics of HAND.

RESUMO

Both HIV-1 infection and smoking may contribute to the development of ageing-related manifestations affecting the prognosis of people living with HIV, but it is unclear whether HIV and smoking exert their effects independently or interact by potentiating each other. We conducted a cross-sectional study in 192 people living with HIV aged- and gender-matched with 192 HIV-uninfected controls, assessing the relative effect of HIV-1/smoking status on lung function (FEV1), bone mineral density (BMD), appendicular skeletal muscle mass index (ASMI), aortic pulse-wave velocity (PWV), insulin resistance (HOMA-IR) and renal function. In both unadjusted and adjusted analyses, FEV1, BMD and ASMI significantly differed according to smoking/HIV status, with the worst parameters found in HIV-1 infected patients currently smoking, and BMD and ASMI decreased to a lesser extent in HIV-1 infected patients formerly smoking (> 10 pack-years). Values in people living with HIV with < 10 pack-years exposure were of similar magnitude to those from controls. Regarding PWV, HOMA-R and eGFR, no significant differences were found, with the exception of eGFR values which were globally lower in HIV-1 infected patients. In conclusion HIV infection and smoking acted synergistically and were associated with a wasting phenotype combining muscle mass and bone mineral reduction.Clinical Trial Registration (registrar, website, and registration number), where applicable: CPP 10-023, 09-027, 10-034.

RESUMO

PURPOSE: We aimed to study the ocular manifestations in human immunodeficiency virus (HIV)-infected patients and the correlation of posterior segment lesions with CD4+ counts. METHODS: This hospital-based, cross-sectional study enrolled HIV-positive patients attending the ophthalmology department of a tertiary care hospital in Eastern India. Complete demographic information was obtained for each patient. Comprehensive ophthalmic evaluation was done in each case. RESULTS: A total of 184 HIV-positive patients were enrolled in the study. Ocular manifestations were detected in 62 cases. The prevalence of ocular manifestations in the present study was 33.69%. Mean age of patients included in the study was 34.8 ± 10.77 years. Prevalence of ocular manifestations was highest in the age group of 30-39 years (41.93%). Highest prevalence of ocular manifestations was noted in patients with low level of education and poor socioeconomic status. Sexual transmission was the major route of HIV transmission (in 92% of cases). Posterior segment lesions were seen in 69.35% of cases. HIV retinopathy was the most common posterior segment manifestation noted in 25 eyes. Significant positive correlation was noted between severities of posterior segment findings and CD4+ counts, which we found to increase with decrease in CD4+ counts (P < 0.001). CONCLUSION: Detailed ophthalmic evaluation including fundus examination is must in all cases of HIV/acquired immunodeficiency syndrome (AIDS) patients as it may help in early diagnosis, treatment, and prevention of sight-threatening complications due to opportunistic infections.

RESUMO

BACKGROUND: Adjunctive glucocorticoids are widely used to treat human immunodeficiency virus (HIV)-associated tuberculous meningitis despite limited data supporting their safety and efficacy. METHODS: We conducted a double-blind, randomized, placebo-controlled trial involving HIV-positive adults (≥18 years of age) with tuberculous meningitis in Vietnam and Indonesia. Participants were randomly assigned to receive a 6-to-8-week tapering course of either dexamethasone or placebo in addition to 12 months of antituberculosis chemotherapy. The primary end point was death from any cause during the 12 months after randomization. RESULTS: A total of 520 adults were randomly assigned to receive either dexamethasone (263 participants) or placebo (257 participants). The median age was 36 years; 255 of 520 participants (49.0%) had never received antiretroviral therapy, and 251 of 484 participants (51.9%) with available data had a baseline CD4 count of 50 cells per cubic millimeter or less. Six participants withdrew from the trial, and five were lost to follow-up. During the 12 months of follow-up, death occurred in 116 of 263 participants (44.1%) in the dexamethasone group and in 126 of 257 participants (49.0%) in the placebo group (hazard ratio, 0.85; 95% confidence interval, 0.66 to 1.10; P = 0.22). Prespecified analyses did not reveal a subgroup that clearly benefited from dexamethasone. The incidence of secondary end-point events, including cases of immune reconstitution inflammatory syndrome during the first 6 months, was similar in the two trial groups. The numbers of participants with at least one serious adverse event were similar in the dexamethasone group (192 of 263 participants [73.0%]) and the placebo group (194 of 257 participants [75.5%]) (P = 0.52). CONCLUSIONS: Among HIV-positive adults with tuberculous meningitis, adjunctive dexamethasone, as compared with placebo, did not confer a benefit with respect to survival or any secondary end point.

RESUMO

BACKGROUND: We identified whether maternal human immunodeficiency virus (HIV) infection during pregnancy affects transplacental transfer of Kaposi sarcoma-associated herpesvirus (KSHV)-specific antibodies and subsequent infant infection. METHODS: We followed pregnant Kenyan women through delivery and their infants until age 2 years. Children were classified as HIV-exposed uninfected (HEU) or HIV-unexposed uninfected (HUU) based on maternal HIV status. Maternal venous and cord blood at delivery and child venous blood every 6 months were tested for antibodies to 20 KSHV antigens by multiplex bead-based immunoassay. Multiple comparisons were adjusted using false discovery rate (FDR). RESULTS: Maternal HIV infection was significantly associated with decreased transplacental transfer of antibodies against all KSHV antigens and lower cord blood levels for 8 antigens at FDR P < .10. Neither birth to 6-month antibody level changes nor 6-month levels differed in HEU and HUU, except for ORF50. By age 24 months, 74% of children KSHV seroconverted but HEU and HUU did not differ in time to seroconversion nor 2-year seropositivity after adjustment for child malaria infection. CONCLUSIONS: Maternal HIV infection reduced a child's initial KSHV antibody levels but did not affect age of infection. Regardless of HIV exposure in utero, KSHV seroconversion in Kenyan children occurred early; associated factors must be identified.

RESUMO

BACKGROUND: Despite the human immunodeficiency virus (HIV) being the most common comorbidity in South African surgical patients, its impact on appendicitis has not been well-described. We aimed to determine HIV status' influence on patients' presentation, assessment, management and outcomes with acute appendicitis. METHODS: The retrospective chart review included all patients aged 12 years and older who were HIV-positive or HIV-negative and presented with acute appendicitis between 1 January 2013 and 31 December 2019. The primary outcome measure was survival to discharge. Secondary outcomes included analysis of the presentation (vital signs), assessment (biochemical, inflammatory markers) and management (intraoperative anatomical severity grading, length of hospital stay). RESULTS: Of the 1096 patients with appendicitis, 196 (17.9%) were HIV-positive, and CD4 counts were available for 159. The median age was 23 years, with the HIV-positive patients being older and HIV-negative group having more males (58.7%). While the HIV-positive patients had a longer median length of hospital stay, there was no statistically significant difference in the two groups' incidence of high-grade appendicitis (p = 0.670). The HIV-positive patients had a higher median shock index (OR 7.65; 95% [CI 2.042-28.64]) than their HIV-negative counterparts. HIV-positivity had a significant association with mortality (OR 9.56; 95% CI [1.68-179.39]), and of the seven HIV-positive patients who died, 66.7% (n = 4) had a CD4 < 200 cells/mm3 (OR 8.6; 95% CI [1.6-63.9]). CONCLUSION: HIV-positive patients, those with CD4 < 200 cells/mm3 or not on ART, have increased mortality risk and may benefit from increased perioperative surveillance. Patients with an unknown HIV status in a high-prevalence population should be offered HIV testing to risk stratify more accurately.

RESUMO

Background: Human immunodeficiency virus (HIV) infection constitutes a major medical complication of pregnancy and is associated with adverse feto-maternal outcomes. However, the relationship between maternal serum selenium levels and pregnancy outcomes has been inconsistent. Objective: This study aimed to determine the relationship between maternal serum selenium status and pregnancy outcome in HIV-positive and HIV-negative women in a tertiary health facility. Methodology: A.comparative cross-sectional study was carried out among HIV-positive and HIV-negative pregnant women at a tertiary health-care facility in Owerri. Participants were recruited from the labor ward and interviewed using a structured questionnaire. One hundred and ten HIV-positive pregnant women were compared with an equal number of HIV-negative pregnant women. They were matched for age, parity and gestational age. Selenium level was measured using atomic absorption spectrophotometer. Maternal packed cell volume (PCV) was also assessed at recruitment. At delivery, the birth weight was measured using a standard weighing scale and documented. Cases of preterm births, perinatal deaths, major congenital abnormalities, and neonatal admission were noted and also documented. Statistical analysis was performed using means and standard deviation. Chi-square test, Student's t-test, logistic regression, and Pearson correlation were also employed. Statistical significance was considered at P < 0.05. Results: HIV-positive pregnant women had significantly lower mean serum selenium concentration compared with HIV-negative pregnant women (64.3 ± 19.6 µg/L vs. 100.1 ± 30.9 µg/L; P < 0.001). There was a statistically significant association between serum selenium concentration and birth weight among both HIV-positive and HIV-negative pregnant women (P < 0.001). Similarly, a statistically significant association was seen between serum selenium and maternal PCV in HIV-positive and HIV-negative pregnant women (P = 0.024 and P < 0.001, respectively). However, there was no association found between serum selenium and other pregnancy outcomes. Conclusion: HIV-positive pregnant women had a lower mean serum selenium level compared to HIV-negative pregnant women. There was a significant association between low maternal serum selenium level and maternal anemia, as well as low birth weight, especially in HIV-positive pregnant women.


Résumé Contexte: L'infection par le virus de l'immunodéficience humaine (VIH) constitue une complication médicale majeure de la grossesse et est associée avec des issues fœto-maternelles défavorables. Cependant, la relation entre les niveaux de sélénium sérique maternel et les résultats de la grossesse aété incohérent. Objectif: Cette étude visait à déterminer la relation entre le statut maternel en sélénium sérique et la grossesse résultat chez les femmes séropositives et séronégatives dans un établissement de santé tertiaire Méthodologie: une étude transversale comparative a été menée auprès de femmes enceintes séropositives et séronégatives dans un établissement de soins de santé tertiaires à Owerri. Les participants étaient recrutés dans la salle de travail et interrogés à l'aide d'un questionnaire structuré. Cent dix femmes enceintes séropositives ont été comparativement à un nombre égal de femmes enceintes séronégatives. Elles ont été appariées pour l'âge, la parité et l'âge gestationnel. Le niveau de sélénium a été mesuré à l'aide d'un spectrophotomètre d'absorption atomique. L'hématocrite maternel (PCV) a également été évalué à recrutement. À l'accouchement, le poids à la naissance a été mesuré à l'aide d'une balance standard et documenté. Des cas de naissances prématurées, de décès périnataux, d'anomalies congénitales majeures et d'admissions néonatales ont été notés et également documentés. L'analyse statistique a été effectuée à l'aide des moyennes et des normes déviation. Le test du chi carré, le test t de Student, la régression logistique et la corrélation de Pearson ont également été utilisés. La signification statistique était considéré à P < 0,05. Résultats: Les femmes enceintes séropositives avaient une concentration sérique moyenne de sélénium significativement plus faible que avec des femmes enceintes séronégatives (64,3 ± 19,6 µg/L vs 100,1 ± 30,9 µg/L ; P < 0,001). Il y avait une association statistiquement significative entre la concentration sérique de sélénium et le poids à la naissance chez les femmes enceintes séropositives et séronégatives (P < 0,001). De la même manière, une association statistiquement significative a été observée entre le sélénium sérique et l'hématocrite maternel chez les femmes enceintes séropositives et séronégatives.femmes (P = 0,024 et P < 0,001, respectivement). Cependant, aucune association n'a été trouvée entre le sélénium sérique et d'autres grossesses. Résultats. Conclusion: les femmes enceintes séropositives avaient un taux sérique moyen de sélénium par rapport aux femmes enceintes séronégatives femmes. Il y avait une association significative entre la faible taux sérique de sélénium et anémie maternelle, ainsi que faible taux de naissance poids, en particulier chez les femmes enceintes séropositives.

RESUMO

BACKGROUND: Psychosocial challenges among human immunodeficiency virus (HIV)-positive patients may promote substance use disorders. This study explored the relationship between conjoint tobacco and alcohol use and depression symptoms among HIV positive patients in Sedibeng District, South Africa. METHODS: In a cross-sectional study of 404 participants, a questionnaire collected information on sociodemography, tobacco and alcohol use and depression symptoms. Outcome measures included the prevalence of conjoint tobacco and alcohol use and its association with positive screen for depression. RESULTS: The mean participant age was 43.2 years. Most completed secondary school (62.9%), were black (99.0%), female (65.8%), unemployed (53.6%) and on antiretroviral therapy (ART) for 1 year (97.8%). Current tobacco use was reported by 23.3% (n = 94) participants with most smoking cigarette (73.7%) and having low nicotine dependence (75.5%). Current alcohol use was reported by 43.6% (n = 176) participants, and 36.9% were categorised as harmful users. Only 7.7% (n = 31) participants screened positive for depression; the prevalence of conjoint tobacco and alcohol use was 19.6% (n = 79) and this was not associated with depression (p = 0.438). Harmful alcohol users were more than five times likely to report conjoint tobacco and alcohol use (p = 0.000), but women were less likely to report it (p = 0.000). CONCLUSION: Conjoint tobacco and alcohol use is common among patients with HIV infection. Although not associated with positive screen for depression, its relationship with harmful alcohol use reiterates the need for an integrated tobacco and alcohol use screening and treatment strategy in the HIV treatment programme in primary care.Contribution: To the authors best knowledge, this study is the first published study that explored the relationship between conjoint tobacco and alcohol use, and depression among HIV-positive patients in the South African primary care settings.

RESUMO

BACKGROUND: Cervical cancer is the leading cause of disability and mortality among women in Africa. Despite a significant correlation between HIV/AIDS and cervical cancer, there is unacceptably low coverage of the uptake of cervical cancer screening among human immunodeficiency virus-positive women in Sub-Saharan Africa. Individual primary studies are limited in explaining the patterns of uptake of cervical cancer screening. This review therefore considers the uptake of cervical cancer screening and its barriers among human immunodeficiency virus-positive women in Sub-Saharan Africa. METHODS: We systematically searched articles published until December 31, 2019, from the PubMed, Cochrane Library, POP LINE, Google Scholar, African Journals Online and JURN databases. The quality of the included articles was assessed by using the Newcastle‒Ottawa Scale, and the coverage of uptake of cervical cancer screening was pooled after checking for heterogeneity and publication bias. The random effect model was used, and subgroup analysis estimates were performed by country. RESULTS: Twenty-one studies comprising 20,672 human immunodeficiency virus-positive women were included. Applying a random effect model, the overall cervical cancer screening uptake among this group of women in Sub-Saharan Africa was estimated to be 30% (95% CI: 19, 41, I2 = 100%). The main barriers to uptake of cervical screening include poor knowledge about cervical cancer and screening, low risk perception of cervical cancer, fear of test result and fear of screening as painful, lack of access to screening services, high cost of screening service, and poor partner attitude and acceptance of the service. The perception of an additional burden of having a cervical cancer diagnosis was found to be a unique barrier among this population of women. CONCLUSION: The unacceptably low coverage of uptake of cervical cancer screening would indicate that the need to scale up the opportunities to these groups of women as well. This review revealed that in addition to structural and health care system barriers, sociocultural and personal barriers are powerful barriers in HIV-positive women. For these cohorts of population, a particular obstacle was discovered to be perception of an additional burden of having cervical cancer.

RESUMO

BACKGROUND: High-risk HPV is considered a major risk factor for the development of cervical cancer, the most common malignancy among women in Uganda. However, there is a paucity of updated epidemiological data on the extent of the burden and factors associated with hr-HPV infection among women of reproductive age. The aim of this study was to determine the prevalence and genotype distribution of hr-HPV and associated factors among women of reproductive age attending a rural teaching hospital in western Uganda. METHODS: We conducted a cross-sectional study from April to June 2022. A total of 216 women of reproductive age attending the gynecological outpatient clinic were consecutively enrolled. Interviewer-administered questionnaires were used to collect participant characteristics, cervical specimens were collected by clinicians, and molecular HPV testing was performed using the Cepheid Xpert HPV DNA test. Descriptive statistics followed by binary logistic regression were conducted using SPSS version 22. RESULTS: The prevalence of hr-HPV was 16.67%. Other hr-HPV types other than HPV 16 and 18 were predominant, with a prevalence of 10.6%; HPV 18/45 (2.31%), HPV 16 (0.46%), and 3.24% of the study participants had more than one hr-HPV genotype. On multivariate logistic regression, an HIV-positive status (aOR = 7.06, CI: 2.77-10.65, p = 0.007), having 3 or more sexual partners in life (aOR = 15.67, CI: 3.77-26.14, p = 0.008) and having an ongoing abnormal vaginal discharge (aOR = 5.37, CI: 2.51-11.49, p = 0.002) were found to be independently associated with hr-HPV infection. CONCLUSIONS AND RECOMMENDATIONS: The magnitude of hr-HPV is still high compared to the global prevalence. HIV-positive women and those in multiple sexual relationships should be prioritized in cervical cancer screening programs. The presence of abnormal vaginal discharge in gynecology clinics should prompt HPV testing.

RESUMO

BACKGROUND: Persistent infection with high-risk human papillomavirus (HPV) is associated with development of invasive cervical cancer. METHODS: Longitudinal data was collected from 174 Senegalese women. We employed marginal Cox proportional hazards models to examine the effect of human immunodeficiency virus (HIV) status (HIV positive vs HIV negative) and HIV type (HIV-1 vs HIV-2 vs dual HIV-1/HIV-2) on clearance of type-specific HPV infection. Analyses were stratified by incident versus prevalent HPV infection. RESULTS: Incident HPV infections in HIV-positive women were less likely to clear than those in HIV-negative women (adjusted hazard ratio [HR] = 0.60; 95% confidence interval [CI], .38-.94). Among HIV-positive women, HIV-2-infected women and HIV-1/2 dually infected women were more likely to clear HPV incident infections than HIV-1-infected women (HR = 1.66; 95% CI, .95-2.92 and HR = 2.17; 95% CI, 1.12-4.22, respectively). Incident HPV infections in HIV-positive women with CD4 cell count ≤500 cells/µL were less likely to clear than those in HIV-positive women with CD4 cell count >500 cells/µL (HR = 0.65; 95% CI, .42-1.01). No significant associations were observed for prevalent HPV infections. CONCLUSIONS: HIV infection reduced the likelihood of clearance of incident HPV infection. Furthermore, among HIV-positive women, low CD4 cell count and dual HIV infection were each associated with reduced likelihood of clearance.

RESUMO

PURPOSE: Invasive cervical cancer (ICC) is associated in nearly 100% with persistent high-risk Human Papillomavirus (HR-HPV) infection. ICC is still one of the leading causes for cancer mortality in women worldwide. The immunosuppressive influence of Human Immunodeficiency Virus (HIV) and the immunocompromised period of pregnancy due to tolerance induction against the hemiallogeneic fetus, are generally risk factors for acquisition and persistence of HR-HPV infections and their progression to precancerous lesions and HPV-associated carcinoma. METHODS: Overall, 81 pregnant women living with HIV (WLWH) were included. A medical history questionnaire was used to record clinical and HIV data. Participants received cervicovaginal cytological smear, colposcopy and HPV testing. HPV test was performed using BSGP5+/6+ PCR with Luminex read-out. The HR-HPV genotypes 16, 18, 31, 33, 45, 52, 58 were additionally grouped together as high-high-risk HPV (HHR-HPV) for the purpose of risk-adapted analysis. RESULTS: HR-HPV prevalence was 45.7%. Multiple HPV infections were detected in 27.2% of participants, of whom all had at least one HR-HPV genotype included. HR-HPV16 and HR-HPV52 were the most prevalent genotypes and found when high squamous intraepithelial lesion (HSIL) was detected by cytology. HIV viral load of ≥ 50 copies/ml was associated with higher prevalence of HR-HPV infections. Whereas, CD4 T cells < 350/µl showed association with occurrence of multiple HPV infections. Time since HIV diagnosis seemed to impact HPV prevalence. CONCLUSION: Pregnant WLWH require particularly attentive and extended HPV-, colposcopical- and cytological screening, whereby clinical and HIV-related risk factors should be taken into account.

RESUMO

BACKGROUND: Over the past decade, the incidence of primary and secondary syphilis has increased dramatically in the United States and Western Europe. Men living with human immunodeficiency virus (HIV) and those at risk of HIV infection experience disproportionately high rates of early syphilis (ES). We compared the odds of ES among HIV-positive and HIV-negative men participating in a status-neutral comprehensive HIV prevention and treatment program (CHP). METHODS: We conducted a retrospective analysis of men aged 18 to 65 years with ≥ 1 CHP visit and ≥2 rapid plasma reagin (RPR) tests performed between January 1, 2018, and December 31, 2021. Early syphilis was defined as newly reactive RPR with a minimum titer of ≥1:4 or a ≥ 4-fold increase in the RPR titer. Multiple logistic regression analyses were performed to determine predictors of ES. RESULTS: A total of 2490 men met the inclusion criteria, of whom 1426 (57.3%) were HIV-positive and 1064 (42.7%) were HIV-negative. Of the 393 men with ES, 284 (72.3%) were HIV-positive and 109 (27.7%) were HIV-negative. Human immunodeficiency virus-positive men had higher adjusted odds of ES (adjusted odds ratio, 2.86; 95% confidence interval, 2.45-3.27) than HIV-negative men did. Chlamydia or gonorrhea infection did not differ according to HIV status (adjusted odds ratio, 0.93; 95% confidence interval, 0.82-1.04). CONCLUSIONS: In our status-neutral care setting, HIV-positive status was associated with significantly higher odds of ES, but not chlamydia or gonorrhea. Our findings emphasize the vulnerability of HIV-positive men to syphilis in an era of effective HIV biomedical prevention.

RESUMO

OBJECTIVES: To examine innate immunity predictors of HIV-1 acquisition as biomarkers of HSV-2 risk and biological basis for epidemiologically established HIV-1 predisposition in HSV-2 infected women. METHODS: We analysed longitudinal samples from HIV-1 negative visits of 1019 women before and after HSV-2 acquisition. We measured cervical and serum biomarkers of inflammation and immune activation previously linked to HIV-1 risk. Protein levels were Box-Cox transformed and ORs for HSV-2 acquisition were calculated based on top quartile or below/above median levels for all HSV-2 negative visits. Bivariate analysis determined the likelihood of HSV-2 acquisition by biomarker levels preceding infection. Linear mixed-effects models evaluated if biomarkers differed by HSV-2 status defined as negative, incident or established infections with an established infection cut-off starting at 6 months. RESULTS: In the cervical compartment, two biomarkers of HIV-1 risk (low SLPI and high BD-2) also predicted HSV-2 acquisition. In addition, HSV-2 acquisition was associated with IL-1ß, IL-6, IL-8, MIP-3α, ICAM-1 and VEGF when below median levels. Systemic immunity predictors of HSV-2 acquisition were high sCD14 and IL-6, with highest odds when concomitantly increased (OR=2.23, 1.49-3.35). Concomitant systemic and mucosal predictors of HSV-2 acquisition risk included (1) serum top quartile sCD14 with cervical low SLPI, VEGF and ICAM-1, or high BD-2; (2) serum high IL-6 with cervical low VEGF and ICAM-1, SLPI, IL-1ß and IL-6; and (3) serum low C reactive protein with cervical high BD-2 (the only combination also predictive of HIV-1 acquisition). Most cervical biomarkers were decreased after HSV-2 acquisition compared with the HSV-2 negative visits, with incident infections associated with a larger number of suppressed cervical biomarkers and lower serum IL-6 levels compared with established infections. CONCLUSIONS: A combination of systemic immunoinflammatory and cervical immunosuppressed states predicts HSV-2 acquisition. A persistently suppressed innate immunity during incident HSV-2 infection may add to the increased HIV-1 susceptibility.

RESUMO

Question: A 35-year-old male with a history of HIV infection presented in our department for endoscopy with the complaints of dyspepsia and epigastric pain. Endoscopy revealed flat, maculopapular, reddish or purplish patchy nodular lesions, with different sizes and shapes, involv- ing both the duodenum and stomach (Figure 1 A-B). There was no sign of complications such as hemorrhage, perforation or obstruction. Physical examination re- vealed that the patient had also purple patchy cutaneous lesions (Figure 2). What is the diagnosis? Answer: Histological assessment from the maculopapular and nodular lesions in endoscopic and cutaneous biopsies revealed the diagnosis as Kaposi sarcoma (KS). KS is a low-grade vascular tumor caused by human herpes virus type 8. KS manifests primarily as a cutaneous disorder, with visceral involvement considered to occur subsequently. Gastrointestinal involvement of KS is rare and most commonly clinically silent. AIDS-related KS that is the most common form of KS in the USA and Europe and the most common malignancy in patients with AIDS. GI involvement by KS is a rare endoscopic finding, still scarcely characterized in the literature (1). In conclusion, involvement of the gastrointestinal tract by KS is often asymptomatic, has multiple endoscopic appearances, and a high diagnostic suspicion is needed in this setting.

RESUMO

Purpose: To study clinical efficacy of valganciclovir in cytomegalovirus retinitis (CMVR) in human immunodeficiency virus (HIV)-positive-positive patients in a tertiary care clinic in a developing nation. Methods: In a retrospective study, systemic and ocular records of HIV patients suffering from CMVR and treated with valganciclovir, were analyzed. Primary outcome measures were involvement of the other eye, incidence of retinal detachment, systemic involvement, and mortality encountered. Secondary outcome measures included change in BCVA. Results: Out of nine patients who were included, two patients developed CMVR in the other eye and only one patient (11.11%) developed retinal detachment during the course of the study. No patient developed any systemic manifestations or had mortality during the course of the study. The change in BCVA was not statistically significant. Conclusion: Use of oral valganciclovir showed good outcome and was found to be a better alternative compared to the use of intravitreal ganciclovir in the literature. Introduction of valganciclovir at an affordable price in developing nations can decrease disease burden.

RESUMO

Background: Anal cancer is primarily caused by high-risk human papillomavirus (hrHPV), is associated with HIV infection, and has a very high incidence among men who have sex with men (MSM). We assessed prevalence of hrHPV, and factors associated with hrHPV in anal canal specimens collected in Dar es Salaam, Tanzania from HIV-positive and HIV-negative MSM. Methods: MSM were recruited using respondent-driven sampling in this cross-sectional study. The primary outcome in this ancillary analysis of 116 MSM was prevalence of HPV-16 and other hrHPV types. Prevalence ratios (PR) estimated the association between hrHPV and HIV-negative participants' demographics, sexual behaviour and sexually transmitted infections. Results: Median age was 23 years and 33.6% of participants were HIV-positive. HrHPV and HPV-16 prevalence was 54.3% and 17.2%, respectively, with HPV-16 prevalence highest among HIV-positive MSM identifying as gay (36.1%) and lowest among HIV-negative MSM identifying as bisexual (2.9%). Having two or more receptive anal sex partners in the past month was associated with hrHPV (PR 3.20, 95%CI 1.69-6.07, vs. 0 partners) among HIV-negative MSM.Conclusions: HrHPV prevalence was high among MSM in Dar es Salaam and highest among HIV-positive MSM identifying as gay. These estimates may be used to support HPV vaccination and screening initiatives.

RESUMO

BACKGROUND: Women living with Human Immunodeficiency Virus (HIV) are at a high risk for early development of cervical cancer. Adherence to cervical cancer prevention strategies in this population is vital for the early detection and treatment of cervical cancer. This study aimed to determine the prevalence and factors associated with cervical cancer screening among HIV-positive women attending an urban HIV care center in Uganda. METHODS: This cross-sectional study included 205 HIV-positive women receiving care at an urban HIV care center. An interviewer-administered questionnaire was used to capture sociodemographic information, history of screening for cervical cancer, and reproductive health characteristics. Logistic regression analysis was used to determine the factors associated with cervical cancer screening. RESULTS: Of the 205 HIV-positive women with a mean age of 37.5 ± 8.87 that participated in the study, majority (n = 201, 98%) were aware of cervical cancer screening. Ninety participants (44%) had ever been screened for cervical cancer and only 33 (16.1%) had been screened in the past year. Obtaining information about cancer of the cervix and cervical cancer screening from health care professionals was significantly associated with higher levels of cervical cancer screening (adjusted odds ratio = 5.61, 95% confidence interval: 2.50-12.61, p value < 0.001). CONCLUSION: This study highlights the low prevalence of cervical cancer screening among HIV-positive women and underscores the role of health professionals as an effective source of information on cervical cancer and cervical cancer screening. Patient education programs in HIV prevention and care facilities should emphasize cervical cancer screening messages to enhance the uptake of screening services.

RESUMO

Pneumocystis jirovecii is a common opportunistic fungal pathogen that commonly affects immunocompromised individuals and can cause P. jirovecii pneumonia. Extrapulmonary P. jirovecii infections are extremely rare. Herein, we present a case of an HIV-positive, antiretroviral therapy-naïve patient who had extrapulmonary pneumocystosis (EPC). He presented with complaints of decreased appetite, abdominal fullness, and weight loss. Computed tomography (CT) revealed multiple low-attenuation masses in the spleen, liver, and both adrenal glands but no pulmonary involvement. A core-needle biopsy of a splenic lesion confirmed the diagnosis of EPC. The patient was initiated on intravenous trimethoprim-sulfamethoxazole (TMP-SMX) and CT-guided percutaneous catheter drainage of the splenic lesion was performed. Intravenous TMP-SMX therapy was completed in 3 weeks and intravenous pentamidine (250 mg daily) therapy was commenced. Pentamidine was completed after 3 weeks, and antiretroviral treatment (ART) was initiated with dolutegravir 50 mg and Descovy HT (emtricitabine [200 mg] and tenofovir alafenamide fumarate [25 mg]). After starting ART, the patient's clinical condition improved, and the abscesses gradually reduced. TMP-SMX is commonly used to treat EPC; however, there is no standard method of treatment. ART may become the key to EPC treatment in individuals with HIV infection.
