Liver Damage in Patients with HCV/HIV Coinfection Is Linked to HIV-Related Oxidative Stress

HIV infection aggravates the progression of liver damage in HCV-coinfected patients, with the underlying pathogenesis being multifactorial. Although high level of oxidative stress has been observed frequently in patients infected with HIV or HCV, the status of oxidative stress in HIV/HCV coinfection and its contribution to HCV liver damage have not been determined. This study involved 363 HBsAg-negative, anti-HCV-positive former blood donors recruited from a village in central China in July 2005; of these, 140 were positive for HIV. Of these 363 subjects, 282 were successfully followed up through July 2009. HIV/HCV-coinfected subjects had higher rates of end-stage liver disease-related death than those monoinfected with HCV. Liver ultrasound manifestations were poor in HIV-positive than in HIV-negative individuals, in both chronic HCV carriers and those with resolved HCV. Serum concentrations of total glutathione (tGSH), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), GSSG, and reduced GSH were higher in HIV-positive than HIV-negative subjects. GSSG concentrations were higher in HIV-infected subjects with abnormal ALT/AST levels than in those with normal ALT/AST levels and were associated with poorer liver ultrasound manifestations. These finding indicated that HIV infection accelerated HCV-associated liver damage in HIV/HCV-coinfected individuals. Increased oxidative stress, induced primarily by HIV coinfection, may contribute to aggravated liver damage.

BACKGROUND: The involvement of free radicals and oxidative stress in HIV infection has been extensively studied, and the benefits of antioxidant supplementation in animal studies have been demonstrated. However, few studies have demonstrated a benefit in clinical studies.OBJECTIVE: To verify the effects of dietary supplementation with Agaricus sylvaticus, a mushroom rich in antioxidants, on the oxidative profile of children born with HIV undergoing antiretroviral therapy.DESIGN: The sample included 24 children (both boys and girls) between two and eight years of age, of whom 10 were HIV positive and received supplementation with Agaricus sylvaticus for a three-month period, and 14 were HIV negative and received no supplementation. At the beginning and conclusion of the study, thiobarbituric acid-reactive substances (TBARS), nitrite and nitrate (NN), Trolox equivalent antioxidant capacity, and the antioxidant capacity of inhibition of diphenyl-picrilhidrazil (DPPH) free radicals were analyzed.RESULTS: Before supplementation, significantly higher values of TBARS and NN, but decreased values of DPPH, were observed in infected subjects when compared with HIV-negative subjects. After supplementation, a reduction of TBARS and NN values and an increase in DPPH and Trolox equivalent antioxidant capacity values were observed in HIV-positive subjects.CONCLUSIONS: The results of the present study suggest the involvement of oxidative stress in HIV infection, with the participation of NN synthesis. Additionally, supplementation reversed oxidative alterations and improved antioxidant defense in infected individuals, and may become a complementary strategy in the treatment of these patients.

ObjectivesHIV-positive men who have sex with men (MSM) may be at a higher risk of repeat syphilis, have different clinical manifestations and have a different serological response to treatment compared with HIV-negative MSM. The objective of this study was to assess whether HIV-negative and HIV-positive MSM with infectious syphilis (primary, secondary or early latent) differed in history of previous syphilis episodes, disease stage and non-treponemal titre of initial and repeat episodes, and the titre response 6 and 12 months after treatment. Furthermore, determinants associated with an inadequate titre response after treatment were explored.MethodsThis retrospective analysis used data of five longitudinal studies (four cohorts; one randomised controlled trial) conducted at the STI clinic in Amsterdam, the Netherlands. Participants were tested for syphilis and completed questionnaires on sexual risk behaviour every 3–6 months. We included data of participants with ≥1 syphilis diagnosis in 2014–2019. Pearson’s χ² test was used to compare HIV-negative and HIV-positive MSM in occurrence of previous syphilis episodes, disease stage of initial and repeat syphilis episode and non-treponemal titre treatment responses.ResultsWe included 355 participants with total 459 syphilis episodes. HIV-positive MSM were more likely to have a history of previous syphilis episodes compared with HIV-negative MSM (68/90 (75.6%) vs 96/265 (36.2%); p<0.001). Moreover, HIV-positive MSM with repeat syphilis were less often diagnosed with primary syphilis (7/73 (9.6%) vs 36/126 (28.6%)) and more often diagnosed with secondary syphilis (16/73 (21.9%) vs 17/126 (13.5%)) and early latent syphilis (50/73 (68.5%) vs 73/126 (57.9%)) (p=0.005). While not significantly different at 12 months, HIV-negative MSM were more likely to have an adequate titre response after 6 months compared with HIV-positive MSM (138/143 (96.5%) vs 66/74 (89.2%); p=0.032).ConclusionsIn repeat syphilis, HIV infection is associated with advanced syphilis stages and with higher non-treponemal titres. HIV infection affects the serological outcome after treatment, as an adequate titre response was observed earlier in HIV-negative MSM.

Background: There is limited data regarding the unique attributes of ischemic stroke among patients infected with human immunodeficiency virus (HIV). There is no published data regarding the occurrence and outcomes of subarachnoid hemorrhage (SAH) among HIV infected persons. Methods: The largest all-payer Nationwide Inpatient Sample (NIS 2002-2010) data was used to identify and analyze all patients presenting with the primary diagnosis of SAH in the United States. Among this cohort, we identified the patients who were not HIV positive and those who were HIV positive. Patient demographics, medical co-morbidities, in-hospital complications, in-hospital procedures, and discharge disposition were compared between the two groups. The association between HIV infection and outcomes was evaluated in multivariate analysis after adjusting for potential confounders. Results: Of the 351,491 patients admitted with SAH, 1367 (0.39%) were infected with HIV. HIV infected patients were younger, mean age [±SD] of 45 ±14.2 years versus those who were not 58±19 years, (p<0.0001). The rate of blood transfusion [27,286 (7.8%) versus 245.6 (18%), p=0.0003], mechanical ventilation [51,199 (14.6%) versus 316.1(23.1%), p=0.008], and sepsis [14,644 (4.2%) versus 236.1 (17.3%), p<0.0001] was significantly higher among HIV infected patients. After adjusting for age, gender, hypertension, coagulopathy, atrial fibrillation, renal failure, and dyslipidemia, HIV negative patients had a significantly higher rate of discharge to home (odds ratio [OR] 1.9, 95% CI: 1.4-2.6, p<0.0001) and lower in-patient mortality (OR 0.4, 95% CI: 0.3-0.5, p<0.001). Further adjustment for blood transfusion and sepsis reduced the odds of discharge to home for the HIV negative patients, from 1.9 to 1.7 but did not affect in-hospital mortality. Conclusion: The in-hospital mortality in HIV infected patients with SAH is higher despite these patients being younger than non-HIV infected patients. We believe that this study provides a nationwide perspective which may have some important implications for early recognition and diagnosis of HIV-infection in SAH patients.

INTRODUCTION: In Brazil there is a large area of overlap of visceral leishmaniasis (VL) and HIV infection, which favored a increased incidence of coinfection Leishmania/HIV. METHODS: This study evaluated 65 consecutive patients with VL and their clinical response to treatment in two health care settings in Belo Horizonte, Brazil. RESULTS: At baseline, the clinical picture was similar between both groups, although diarrhea and peripheral lymphadenomegaly were more frequent in HIV-infected subjects. HIV-positive patients had lower median blood lymphocyte counts (686/mm³ versus 948/mm³p = 0.004) and lower values of alanine aminotransferase (ALT) (48IU/L versus 75.6IU/L p = 0.016) than HIV-negative patients. HIV-positive status (hazard ratio = 0.423, p = 0.023) and anemia (HR = 0.205, p = 0.002) were independent negative predictors of complete clinical response following antileishmanial treatment initiation. CONCLUSIONS: This study reinforces that all patients with VL should be tested for HIV infection, regardless of their clinical picture. This practice would allow early recognition of coinfection with initiation of antiretroviral therapy and, possibly, reduction in treatment failure.

Lunula is the white, half-moon shaped area seen in proximal ends of some nails. Though a few studies have described the nail changes that can occur in association with HIV infection, none of these paid much attention to lunula. Aims and Objectives. To study the lunula in fingernails among HIV infected patients. Materials and Methods. An observational, cross-sectional study to record presence of lunula in 168 HIV-positive patients and compare it with age and sex matched 168 healthy HIV-negative control. Anolunula (absence of lunula) in HIV-positive patients was correlated with CD4 counts, stages of HIV infection, time since patient was diagnosed as HIV-positive, and status of antiretroviral therapy. Results. Anolunula was present in significantly more fingernails in HIV-positive patients compared to HIV-negative controls. There was a highly significant difference for total anolunula (anolunula in all fingernails) in study and control group. Incidence of total anolunula was directly proportional to the stage of HIV infection, increasing progressively as the HIV infection advances from stage 1 to stage 4. Conclusion. Absence of lunula is related to not only HIV infection per se but also the stages of HIV infection.

ABSTRACT Infections caused by the human immunodeficiency virus (HIV) and by the larvae of Taenia solium (i.e., cysticercosis) are still widespread in many developing countries. Both pathologies modify host immune status and it is possible that HIV infection may modulate the frequency and pathogeny of cysticercosis of the central nervous system (i.e., neurocysticercosis [NCC]). Objective: To describe published cases of NCC among HIV-positive patients and to evaluate whether the characteristics of NCC, including frequency, symptoms, radiological appearance, and response to treatment differed between HIV-positive and HIV-negative patients. Methods: Forty cases of NCC/HIV co-infected patients were identified in the literature. Clinical and radiological characteristics, as well as response to treatment, were compared with non-matching historical series of NCC patients without HIV infection. Results: Most of these patients had seizures and multiple vesicular parasites located in parenchyma. Clinical and radiological characteristics were similar between HIV-positive and HIV-negative patients with NCC, as well as between immunocompromised and non-immunocompromised HIV-positive patients. Conclusion: Our review did not reveal clear interactions between HIV and NCC. This may be partially due to the small number of cases and reliance on published research. A systematic, multi-institutional effort aiming to report all the cases of this dual pathology is needed to confirm this finding and to clarify the possible relationship between both pathogens.

Purpose To evaluate and determine predictors of squamous cell carcinoma of the anus (SCCA) outcomes in the highly active antiretroviral therapy (HAART) era for HIV-positive and -negative individuals using large national Veterans Affairs (VA) Administration databases. Patients and Methods We used the VA administrative databases to perform a retrospective cohort study in 1,184 veterans diagnosed with SCCA between 1998 and 2004. We calculated HIV infection rates and used logistic regression to identify epidemiologic factors that were associated with HIV infection. Kaplan-Meier curves and Cox proportional hazards models were calculated to compare survival between HIV-positive and HIV-negative veterans. Results In our cohort, 175 patients (15%) were HIV positive. The median age of the HIV-negative and -positive patients was 63 and 49 years, respectively (P < .001). Individuals with HIV were eight times more likely to be male (P = .01) and three times more likely to be African American (P < .001). There were no differences between HIV-positive and HIV-negative individuals in the receipt of treatment. The 2-year observed survival rates were 77% and 75% among HIV-positive and HIV-negative individuals, respectively. In multivariate Cox analysis, significant predictors of survival were age, sex, metastasis at diagnosis, and comorbidity score. HIV infection did not affect survival. Conclusion A noteworthy proportion of individuals with SCCA in the VA system are HIV positive. HIV-associated SCCA seems mainly to be a disease among younger men. Survival of SCCA is equivalent between HIV-positive and HIV-negative individuals in the HAART era. Treatment should not be withheld or deintensified based on HIV status.

Background/aimsIn the era of increasing incidence of syphilis globally, ocular syphilis is re-emerging as an important cause of uveitis. The aim of this study was to determine the clinical and laboratory characteristics of ocular- and neurosyphilis among individuals with and without HIV infection.MethodsRetrospective analysis of patients diagnosed with ocular syphilis presenting to Tygerberg Hospital, South Africa, over a 5-year period ending December 2018.ResultsTwo-hundred and fifteen eyes of 146 patients were included. HIV coinfection was present in 52.1% of the patients, with 23.7% of these patients being newly diagnosed on presentation. The median age was 36.5±9.8 years. Bilateral involvement occurred in 47.3%, with 68.1% of these patients being HIV positive. The most frequent form of intraocular inflammation was posterior uveitis (40.9%), followed by panuveitis (38.1%), both of which were more predominant in HIV-positive eyes. Seventy-four per cent of all eyes had a visual acuity ≤20/50 and 40% <20/200 at presentation. A lumbar puncture was performed in 113 patients (77.4%). Sixteen patients had confirmed neurosyphilis and 27 probable neurosyphilis according to the UpToDate algorithms.ConclusionThis study included the largest number of ocular syphilis cases with the largest proportion of HIV infection to date. Forty-three of 146 patients (37.0%) had neurosyphilis. HIV status must be determined in all patients with ocular syphilis since almost ¼ of patients were newly diagnosed with HIV infection by doing so.

ABSTRACT Macrophage inflammatory protein-1α (MIP-1α) and MIP-1β play an important role in modulating immune responses. To understand their importance in immunity to placental malaria (PM) and in human immunodeficiency virus (HIV)-PM coinfection, we investigated levels of these chemokines in the placental intervillous blood plasma (IVB plasma) and cord blood plasma of HIV-negative PM-negative, HIV-negative PM-positive, HIV-positive PM-negative, and HIV-positive PM-positive women. Compared to HIV-negative PM-negative women, the MIP-1β concentration in IVB plasma was significantly elevated in HIV-negative PM-positive women and HIV-positive PM-positive women, but it was unaltered in HIV-positive PM-negative women. Also, PM-infected women, irrespective of their HIV status, had significantly higher levels of MIP-1β than HIV-positive PM-negative women. The MIP-1α level was not altered in association with either infection. The IVB plasma levels of MIP-1α and MIP-1β positively correlated with the cord blood plasma levels of these chemokines. As with IVB plasma, only cord plasma from PM-infected mothers had significantly elevated levels of MIP-1β compared to PM-negative mothers, irrespective of their HIV infection status. MIP-1β and MIP-1α levels in PM-positive women were positively associated with parasite density and malaria pigment levels. Regardless of HIV serostatus, the IVB MIP-1β level was significantly lower in women with PM-associated anemia. In summary, an elevated level of MIP-1β was associated with PM. HIV infection did not significantly alter these two chemokine levels in IVB plasma.
