    HIV-related eye disease can be classified as retinal HIV microangiopathy, opportunistic infections, neuro-ophthalmic manifestations and unusual malignancies. There is a 52-100% lifetime accumulative risk of HIV patients developing eye problems. Seventy-seven per cent of patients with ocular manifestations of HIV had CD4 counts 100 cells/μL for a minimum of three months. Despite HAART, patients with a CD4 count PORN), less commonly toxoplasmosis, pneumocystis and cryptococcus. Malignancies associated with HIV include Kaposi's sarcoma and conjunctival squamous cell carcinoma. Cranial nerve palsies, optic disc swelling and atrophy are characteristic neuro-ophthalmic features. They usually occur secondary to meningitis/encephalitis (from cryptococcus and tuberculosis). With the advent of HAART, new complications have developed in CMV retinitis: immune recovery uveitis (IRU) and cystoid macula oedema (CMO). Immune recovery uveitis occurs in 71% of patients if HAART is started before the induction of the anti-CMV treatment. However, this is reduced to 31% if HAART is started after the induction treatment. Molluscum contagiosum and Kaposi's sarcoma can spontaneously resolve on HAART. Highly active anti-retroviral therapy has reduced the frequencies of opportunistic infections and improved the remission duration in HIV patients. PMID:24756590

    Full Text Available Immune reconstitution inflammation syndrome typically occurs within days after patients undergo highly active anti-retroviral therapy and is a big hurdle for effective treatment of AIDS patients. In this study, we monitored immune reconstitution inflammation syndrome occurrence in 238 AIDS patients treated with highly active anti-retroviral therapy. Among them, immune reconstitution inflammation syndrome occurred in 47 cases (19.7%. Immune reconstitution inflammation syndrome patients had significantly higher rate of opportunistic infection (p < 0.001 and persistently lower CD4+ cell count (p < 0.001 compared to the non-immune reconstitution inflammation syndrome patients. In contrast, no significant differences in HIV RNA loads were observed between the immune reconstitution inflammation syndrome group and non-immune reconstitution inflammation syndrome group. These data suggest that a history of opportunistic infection and CD4+ cell counts at baseline may function as risk factors for immune reconstitution inflammation syndrome occurrence in AIDS patients as well as potential prognostic markers. These findings will improve the management of AIDS with highly active anti-retroviral therapy.

  4. Hypermetabolic subcutaneous fat in patients on highly active anti-retroviral therapy treatment: Subtle finding with implications

    Lipodystrophy (LD) is a serious complication of highly active anti-retroviral therapy, characterized by peripheral fat wasting, central adiposity and metabolic changes. Since the disfiguration caused by LD is permanent, the focus of management is on early detection to arrest progression. We report a case where ancillary finding of increased fluorine-18 fluoro-2-deoxyglucose (F-18 FDG) uptake in the sub-cutaneous fat helped early detection of LD and led to early intervention to arrest progression. Though F-18 FDG positron emission tomography/computed tomography scan is not recommended to diagnose LD, conscious reporting of this finding when present can greatly influence patient management

    Full Text Available Objective: Introduction of new approaches for the treatment of human immunodeficiency virus (HIV infection such as anti-retroviral medicines has resulted in an increase in the life expectancy of HIV patient. Evaluating the dental health status as a part of their general health care is needed in order to improve the quality of life in these patients. The aim of this study was to compare the root and crown caries rate in HIV patients receiving highly active antiretroviral therapy (HAART with that rate in HIV patients without treatment option. Materials and Methods: This cross sectional study consisting of 100 individuals of both genders with human immunodeficiency virus were divided into two groups: i. group 1 (treatment group including 50 patients with acquired immunodeficiency syndrome (AIDS receiving HAART and ii. group 2 (control group including 50 HIV infected patients not receiving HAART. Dental examinations were done by a dentist under suitable light using periodontal probe. For each participant, numbers of decay (D, missed (M, filled (F, Decayed missed and filled teeth (DMFT, decay surface (Ds, missed surface (Ms, filled surface (Fs, Decayed missed and filled surfaces (DMFS, and tooth and root caries were recorded. Data were analyzed using Chi-square test and independent t test using SPSS 13.0, while p-value of <0.05 was considered statistically significant in all analysis. Results: The mean and standard deviation (SD of decayed, missed and filled teeth of those who were on highly active antiretroviral therapy was 6.86 ± 3.57, 6.39 ± 6.06 and 1.89 ± 1.93, respectively. There was no significant difference between these values regarding to the treatment of patients. The mean and standard deviation of DMFT, DMFS and the number of decayed root surfaces were 15.14 ± 6.09, 56.79 ± 28.56, and 4.96 ± 2.89 in patients treated by anti-retroviral medicine which were not significantly different compared to those without this treatment

    Although highly active retroviral therapy (HAART) has been extremely effective in lowering AIDS incidence among patients infected with HIV, certain drugs included in HAART can cause serious mitochondrial toxicities. One of the most frequent adverse events is lipoatrophy, which is the loss of subcutaneous fat in the face, arms, buttocks and/or legs as an adverse reaction to nucleoside reverse transcriptase inhibitors (NRTIs). The clinical symptoms of lipoatrophy resemble those of inherited mit...

  7. Immune reconstitution inflammatory syndrome in HIV-infected patients with mycobacterial infections starting highly active anti-retroviral therapy

    AIM: To describe the radiological appearances of immune reconstitution inflammatory syndrome (IRIS) in human immunodeficiency virus (HIV)-infected patients with mycobacterial infections starting highly active anti-retroviral therapy (HAART). MATERIALS AND METHODS: Five consecutive HIV infected patients with IRIS due to mycobacterial infection were studied. Intercurrent infection and poor drug compliance were excluded as causes of presentation. The chest radiological appearances at the time of starting HAART and at the time of diagnosis of IRIS were compared. RESULTS: In these five patients there was clinical and radiological deterioration, occurring between 10 days and 7 months after starting HAART, leading to unmasking of previously undiagnosed mycobacterial infection or to worsening of mycobacterial disease. All five patients had HAART-induced increases in CD4+ T lymphocyte counts and reductions in peripheral blood HIV 'viral load'. Chest radiographic abnormalities due to IRIS included marked mediastinal lymphadenopathy in three patients--severe enough to produce tracheal compression in two patients (one of whom had stridor)--and was associated with new pulmonary infiltrates in two patients. The other two patients had new infiltrates, which in one patient was associated with a pleural effusion. CONCLUSION: These cases illustrate the diverse chest radiographic appearances of IRIS occurring after HAART in patients with mycobacterial and HIV co-infection. Marked mediastinal lymphadenopathy occurred in three of these five patients (with associated tracheal narrowing in two patients); four patients developed pulmonary infiltrates and one had an effusion. The cases further highlight that the onset of IRIS may be delayed for several months after HAART is started

    2014-01-01

    Full Text Available Background: Crystalluria is associated with some highly active anti-retroviral therapies (HAART′s used in the management of HIV/AIDS. Aims: This study used light microscopy to establish the prevalence of crystalluria among HIV/AIDS patients on HAART and identified the routine crystals present in their urine. Materials and Methods: In this simple randomised cross-sectional study, 200 HIV/AIDS participants, comprising 150 on HAART and 50 HAART-naοve were recruited from the HIV clinic at the Komfo Anokye Teaching Hospital (KATH. Urine and blood samples were collected, for urinalysis and the determination of the CD4 count, respectively. A well-structured pre-tested questionnaire was used to obtain socio-demographic data and clinical history of the participants. Results: The prevalence of crystalluria was higher among HIV-infected persons on HAART than those not on HAART (6.7% vs 4%; P = 0.733. Calcium oxalate and triple phosphate crystals were the crystal types present in their urine (3.5% and 2.5%, respectively and was present only in HIV subjects on first line of treatment (without protease inhibitors. Participants aged between 40-50 years and those with hypersthenuria and acidic urine had the highest amount of crystalluria (41.6%, 83.3%, and 58.3%, respectively. Conclusion: HAART is associated with crystalluria in HIV patients. Light microscopy will be of disgnostic value in resource limited settings.

Lifelong adherence to anti-retroviral therapy (ART is vital to improve the patient’s state of well-being and to prevent the development of strains of the human immunodef ciency virus (HIV that are resistant to ART. Persons with ART-resistant strains of HIV can spread these to other people, requiring more expensive ART with more severe side-effects and poorer health outcomes. The purpose of this exploratory, descriptive, qualitative study was to determine nurses’ perspectives on Botswana patients’ anti-retroviral therapy (ART adherence, and to identify factors which could promote or hinder ART adherence. Four ART sites were randomly selected and all 16 nurses providing ART services at these sites participated in semi-structured interviews. These nurses indicated that patients’ ART adherence was inf uenced by service-related and patient-related factors. Service-related factors included the inaccessibility of ART clinics, limited clinic hours, health workers’ inability to communicate in patients’ local languages, long waiting times at clinics and delays in being informed about their CD4 and viral load results. Nurses could not trace defaulters nor contact them by phone, and also had to work night shifts, disrupting nurse-patient relationships. Patient-related factors included patients’ lack of education, inability to understand the significance of CD4 and viral load results, financial hardships, non-disclosure and non-acceptance of their HIV positive status, alcohol abuse, the utilisation of traditional medicines and side effects of ART. The challenges of lifelong ART adherence are multifaceted involving both patient-related and service-related factors. Supplying free ARVs does not ensure high levels of ART adherence.

    2010-12-01

    Full Text Available Abstract Background The psychosocial development of pediatric HIV patients has not been extensively evaluated. The study objectives were to evaluate whether emotional and social functions are differentially associated with HIV-related complications. Methods A matched case-control study design was conducted. The case group (n = 20 consisted of vertically infected children with HIV (aged 3-18 years receiving HAART in Greece. Each case was matched with two randomly selected healthy controls from a school-based population. CNS imaging and clinical findings were used to identify patients with HIV-related neuroimaging abnormalities. The Wechsler Intelligence Scale III and Griffiths Mental Abilities Scales were applied to assess cognitive abilities. The age specific Strengths and Difficulties Questionnaire was used to evaluate emotional adjustment and social skills. The Fisher's exact test, student's t-test, and Wilcoxon rank sum test were used to compare categorical, continuous, and ordinal scores, respectively, of the above scales between groups. Results HIV patients without neuroimaging abnormalities did not differ from patients with neuroimaging abnormalities with respect to either age at HAART initiation (p = 0.306 or months of HAART treatment (p = 0.964. While HIV patients without neuroimaging abnormalities had similar cognitive development with their healthy peers, patients with neuroimaging abnormalities had lower mean General (p = 0.027 and Practical (p = 0.042 Intelligence Quotient scores. HIV patients without neuroimaging abnormalities had an increased likelihood of both Abnormal Emotional Symptoms (p = 0.047 and Hyperactivity scores (p = 0.0009. In contrast, HIV patients with neuroimaging abnormalities had an increased likelihood of presenting with Abnormal Peer Problems (p = 0.033. Conclusions HIV patients without neuroimaging abnormalities are more likely to experience maladjustment with respect to their emotional and activity spheres

    2009-06-01

    We have assessed the efficacy of anti retroviral therapy (ART) using undetectable viral load (VL) (<50 RNA copies\\/ml) as a marker of virological success, in patients who have Human Immunodeficiency Virus (HIV) attending the Department of Infectious Disease. A cross-sectional review of patients\\' case notes was used to obtain their demographics and treatment details. 79% (253) of the hospital case notes of clinic population was available for analysis, which represents 90% of those receiving ART in the clinic. 166\\/253 of the cohort were receiving treatment at the time of this study and 95% (157\\/166) of these were on treatment for greater than 6 months. The total virological success rate is 93%, which is comparable to other centres and are as good as those from published clinical trials. 56% of those on therapy who have virological failure were Intravenous Drug Users (IVDUs). Case by case investigation for those with treatment failure is warranted.

    2009-07-01

    Full Text Available Abstract Background As the resource implications of expanding anti-retroviral therapy (ART are likely to be large, there is a need to explore its cost-effectiveness. So far, there is no such information available from Ethiopia. Objective To assess the cost-effectiveness of ART for routine clinical practice in a district hospital setting in Ethiopia. Methods We estimated the unit cost of HIV-related care from the 2004/5 fiscal year expenditure of Arba Minch Hospital in southern Ethiopia. We estimated outpatient and inpatient service use from HIV-infected patients who received care and treatment at the hospital between January 2003 and March 2006. We measured the health effect as life years gained (LYG for patients receiving ART compared with those not receiving such treatment. The study adopted a health care provider perspective and included both direct and overhead costs. We used Markov model to estimate the lifetime costs, health benefits and cost-effectiveness of ART. Findings ART yielded an undiscounted 9.4 years expected survival, and resulted in 7.1 extra LYG compared to patients not receiving ART. The lifetime incremental cost is US$2,215 and the undiscounted incremental cost per LYG is US$314. When discounted at 3%, the additional LYG decreases to 5.5 years and the incremental cost per LYG increases to US$325. Conclusion The undiscounted and discounted incremental costs per LYG from introducing ART were less than the per capita GDP threshold at the base year. Thus, ART could be regarded as cost-effective in a district hospital setting in Ethiopia.

  4. Circulating heat shock protein 60 levels are elevated in HIV patients and are reduced by anti-retroviral therapy.

    Itaru Anraku

    Full Text Available Circulating heat shock protein 60 (Hsp60 and heat shock protein 10 (Hsp10 have been associated with pro- and anti-inflammatory activity, respectively. To determine whether these heat shock proteins might be associated with the immune activation seen in HIV-infected patients, the plasma levels of Hsp60 and Hsp10 were determined in a cohort of 20 HIV-infected patients before and after effective combination anti-retroviral therapy (cART. We show for the first time that circulating Hsp60 levels are elevated in HIV-infected patients, with levels significantly reduced after cART, but still higher than those in HIV-negative individuals. Hsp60 levels correlated significantly with viral load, CD4 counts, and circulating soluble CD14 and lipopolysaccharide levels. No differences or correlations were seen for Hsp10 levels. Elevated circulating Hsp60 may contribute to the immune dysfunction and non-AIDS clinical events seen in HIV-infected patients.

  8. In vivo mitochondrial function in HIV-infected persons treated with contemporary anti-retroviral therapy: a magnetic resonance spectroscopy study.

    Brendan A I Payne

    Full Text Available Modern anti-retroviral therapy is highly effective at suppressing viral replication and restoring immune function in HIV-infected persons. However, such individuals show reduced physiological performance and increased frailty compared with age-matched uninfected persons. Contemporary anti-retroviral therapy is thought to be largely free from neuromuscular complications, whereas several anti-retroviral drugs previously in common usage have been associated with mitochondrial toxicity. It has recently been established that patients with prior exposure to such drugs exhibit irreversible cellular and molecular mitochondrial defects. However the functional significance of such damage remains unknown. Here we use phosphorus magnetic resonance spectroscopy ((31P-MRS to measure in vivo muscle mitochondrial oxidative function, in patients treated with contemporary anti-retroviral therapy, and compare with biopsy findings (cytochrome c oxidase (COX histochemistry. We show that dynamic oxidative function (post-exertional ATP (adenosine triphosphate resynthesis was largely maintained in the face of mild to moderate COX defects (affecting up to ∼10% of fibers: τ½ ADP (half-life of adenosine diphosphate clearance, HIV-infected 22.1±9.9 s, HIV-uninfected 18.8±4.4 s, p = 0.09. In contrast, HIV-infected patients had a significant derangement of resting state ATP metabolism compared with controls: ADP/ATP ratio, HIV-infected 1.24±0.08×10(-3, HIV-uninfected 1.16±0.05×10(-3, p = 0.001. These observations are broadly reassuring in that they suggest that in vivo mitochondrial function in patients on contemporary anti-retroviral therapy is largely maintained at the whole organ level, despite histochemical (COX defects within individual cells. Basal energy requirements may nevertheless be increased.

  9. Economic evaluation of task-shifting approaches to the dispensing of anti-retroviral therapy

    2012-09-01

    Full Text Available Abstract Background A scarcity of human resources for health has been identified as one of the primary constraints to the scale-up of the provision of Anti-Retroviral Treatment (ART. In South Africa there is a particularly severe lack of pharmacists. The study aims to compare two task-shifting approaches to the dispensing of ART: Indirectly Supervised Pharmacist’s Assistants (ISPA and Nurse-based pharmaceutical care models against the standard of care which involves a pharmacist dispensing ART. Methods A cross-sectional mixed methods study design was used. Patient exit interviews, time and motion studies, expert interviews and staff costs were used to conduct a costing from the societal perspective. Six facilities were sampled in the Western Cape province of South Africa, and 230 patient interviews conducted. Results The ISPA model was found to be the least costly task-shifting pharmaceutical model. However, patients preferred receiving medication from the nurse. This related to a fear of stigma and being identified by virtue of receiving ART at the pharmacy. Conclusions While these models are not mutually exclusive, and a variety of pharmaceutical care models will be necessary for scale up, it is useful to consider the impact of implementing these models on the provider, patient access to treatment and difficulties in implementation.

    Full Text Available Abstract Background Ensuring good adherence is critical to the success of anti-retroviral treatment (ART. However, in resource-poor contexts, where paediatric HIV burden is high there has been limited progress in developing or adapting tools to support adherence for HIV-infected children on ART and their caregivers. We conducted formative research to assess children's adherence and to explore the knowledge, perceptions and attitudes of caregivers towards children's treatment. Methods All children starting ART between September 2002 and January 2004 (when ART was at cost in Malawi were observed for at least 6 months on ART. Their adherence was assessed quantitatively by asking caregivers of children about missed ART doses during the previous 3 days at monthly visits. Attendance to clinic appointments was also monitored. In June and July 2004, four focus group discussions, each with 6 to 8 caregivers, and 5 critical incident narratives were conducted to provide complementary contextual data on caregivers' experiences on the challenges to and opportunities of paediatric ART adherence. Results We followed prospectively 47 children who started ART between 8 months and 12 years of age over a median time on ART of 33 weeks (2–91 weeks. 72% (34/47 never missed a single dose according to caregivers' report and 82% (327/401 of clinic visits were either as scheduled, or before or within 1 week after the scheduled appointment. Caregivers were generally knowledgeable about ART and motivated to support children to adhere to treatment despite facing multiple challenges. Caregivers were particularly motivated by seeing children begin to get better; but faced challenges in meeting the costs of medicine and transport, waiting times in clinic, stock outs and remembering to support children to adhere in the face of multiple responsibilities. Conclusion In the era of rapid scale-up of treatment for children there is need for holistic support strategies that focus

    2011-01-01

    The effects of HIV/AIDS have been far-reaching in Africa. Beyond adverse health outcomes and the tremendous toll on life, AIDS has serious economic impacts on households, increasing livelihood insecurity while simultaneously depleting socio-economic resources. Although microfinance is believed to have the potential to mitigate the economic impacts of HIV by helping affected households and communities better prepare for and cope with HIV-related economic shocks, little empirical research exists on this subject. This qualitative study examines the socio-economic impacts of economic strengthening activities on people living with HIV (PLHIV) in the era of increased access to anti-retroviral therapy to determine if savings-led, community-managed microfinance is a justified activity for HIV programmes. Findings from a village savings and loan programme, implemented by CARE International in Cote d'Ivoire, revealed that when appropriate medical treatment is available PLHIV are capable of participating in and benefit from microfinance activities, which increased HIV-positive clients' access to money and economic self-sufficiency. By bringing individuals with similar experiences together, savings and loan groups also acted as self-support groups providing psychosocial support while reducing stigmatisation and increasing members' sense of dignity and self-worth.

    2012-01-01

    Objective: To assess early mortality and identify its predictors among the ART naive HIV-infected patients initiating anti retroviral therapy (ART) available free of cost at the ART Centres.Methods: A retrospective cohort analysis of routinely collected programme data was done for assessing mortality of all ART naive adult patients who received first-line ART at a government tertiary care hospital in eastern India during 1st March 2009 and 28th February 2010. Bivariate and multiple regression analyses of the baseline demographic, clinical and laboratory records using SPSS 15.0 were done to identify independent predictors of mortality. Results: The mortality rate at one year was estimated to be 7.66 (95% CI 5.84-9.83) deaths/100 patient-years and more than 50% of the deaths occurred during first three months of ART initiation with a median time interval of 73 days. Tuberculosis was the major cause of death. ART naive patients with baseline serum albumin <3.5 mg/dL were eight (OR 7.9; 95% CI: 3.8-16.5) at risk of death than those with higher serum albumin levels and patients with CD4 count <100 cells/μL were two times (OR 2.2;95% CI: 1.1-4.4) at risk of death compared to higher CD4 counts. Conclusions: Risk of mortality is increased when ART is initiated at advanced stages of immunosuppression denoted by low serum albumin levels and CD4 cell counts. This highlights the importance of early detection of HIV infection, early management of opportunistic infections including tuberculosis and timely initiation of the antiretroviral drugs in the resource-limited countries, now available free in the Indian national ART programme.

    Psychological distress is common among adolescents living with HIV (ALHIV) worldwide, and has been associated with non-adherence to anti-retroviral therapy (ART), leading to poor virologic suppression, drug resistance, and increased risk for AIDS morbidity and mortality. However, only a few studies have explored the relationship between psychological distress and ART adherence among adolescents in sub-Saharan Africa. The paper examines the relationship between psychological distress and ART adherence, and effect of psychosocial resources on ART adherence. We conducted a cross-sectional survey of 464 ALHIV (aged 12-19; 53% female) seeking HIV care at a large HIV treatment center in Kampala, Uganda. ALHIV were recruited during routine clinic visits. Three self-reported binary adherence measures were utilized: missed pills in the past three days, non-adherence to the prescribed medical regimen, and self-rated adherence assessed using a visual analog scale. Psychological distress was measured as a continuous variable, and computed as the mean score on a locally developed and validated 25-item symptom checklist for Ugandan ALHIV. Psychosocial resources included spirituality, religiosity, optimism, social support, and coping strategies. After adjusting for respondents' socio-demographic characteristics and psychosocial resources, a unit increase in psychological distress was associated with increased odds of missing pills in past 3 days (Odds Ratio(OR) = 1.75; Confidence Interval (CI): 1.04-2.95), not following the prescribed regimen (OR = 1.63; CI: 1.08-2.46), and lower self-rated adherence (OR = 1.79; CI: 1.19-2.69). Psychosocial resources were associated with lower odds for non-adherence on all three self-report measures. There is a need to strengthen the psychosocial aspects of adolescent HIV care by developing interventions to identify and prevent psychological distress among Ugandan ALHIV. PMID:27294696

    Highly active antiretroviral therapy (HAART) has greatly improved health parameters of HIV infected individuals. However, there are several challenges associated with the chronic nature of HAART administration. For populations in health transition, dual use of medicinal plant extracts and conventional medicine poses a significant challenge. There is need to evaluate interactions between commonly used medicinal plant extracts and antiretroviral drugs used against HIV/AIDS. Efavirenz (EFV) and nevirapine (NVP) are the major components of HAART both metabolized by CYP2B6, an enzyme that can potentially be inhibited or induced by compounds found in medicinal plant extracts. The purpose of this study was to evaluate the effects of extracts of selected commonly used medicinal plants on CYP2B6 enzyme activity. Recombinant human CYP2B6 was used to evaluate inhibition, allowing the assessment of herb-drug interactions (HDI) of medicinal plants Hyptis suaveolens, Myrothamnus flabellifolius, Launaea taraxacifolia, Boerhavia diffusa and Newbouldia laevis. The potential of these medicinal extracts to cause HDI was ranked accordingly for reversible inhibition and also classified as potential time-dependent inhibitor (TDI) candidates. The most potent inhibitor for CYP2B6 was Hyptis suaveolens extract (IC50 = 19.09 ± 1.16 µg/mL), followed by Myrothamnus flabellifolius extract (IC50 = 23.66 ± 4.86 µg/mL), Launaea taraxacifolia extract (IC50 = 33.87 ± 1.54 µg/mL), and Boerhavia diffusa extract (IC50 = 34.93 ± 1.06 µg/mL). Newbouldia laevis extract, however, exhibited weak inhibitory effects (IC50 = 100 ± 8.71 µg/mL) on CYP2B6. Launaea taraxacifolia exhibited a TDI (3.17) effect on CYP2B6 and showed a high concentration of known CYP450 inhibitory phenolic compounds, chlorogenic acid and caffeic acid. The implication for these observations is that drugs that are metabolized by CYP2B6 when co-administered with these herbal medicines and when adequate amounts of the extracts

    Full Text Available Over 90 per cent of HIV infected babies were born to HIV positive mothers in Sub-Saharan Africa and worldwide. It is estimated that currently 2.3 million i.e 5.9% are children less than 15 yrs of age infected with HIV. Worldwide, children under age 15 who were newly infected with HIV, more than 90 percent were babies were born to HIV-positive women. An estimated 1500 children get newly infected with HIV each day globally. The scenario is similar at home in Andhra Pradesh, India. This present exploratory study is to find out the effectiveness of fixed drug combination of antiretroviral therapy in children. The results are encouraging and are similar to results from such studies elsewhere.

    Full Text Available Abstract Background This trial aims at testing the efficacy of weekly reminder and motivational text messages, compared to usual care in improving adherence to Highly Active Antiretroviral Treatment in patients attending a clinic in Yaoundé, Cameroon. Methods and Design This is a single-centered randomized controlled single-blinded trial. A central computer generated randomization list will be generated using random block sizes. Allocation will be determined by sequentially numbered sealed opaque envelopes. 198 participants will either receive the mobile phone text message or usual care. Our hypothesis is that weekly motivational text messages can improve adherence to Highly Active Antiretroviral Treatment and other clinical outcomes in the control group by acting as a reminder, a cue to action and opening communication channels. Data will be collected at baseline, three months and six months. A blinded program secretary will send out text messages and record delivery. Our primary outcomes are adherence measured by the visual analogue scale, self report, and pharmacy refill data. Our secondary outcomes are clinical: weight, body mass index, opportunistic infections, all cause mortality and retention; biological: Cluster Designation 4 count and viral load; and quality of life. Analysis will be by intention-to-treat. Covariates and subgroups will be taken into account. Discussion This trial investigates the potential of SMS motivational reminders to improve adherence to Highly Active Antiretroviral Treatment in Cameroon. The intervention targets non-adherence due to forgetfulness and other forms of non-adherence.

  5. Cancellers - Exploring the Possibility of Receptor Decoy Traps As a Superior Anti-Retroviral Strategy.

    Jeremiah, Sundararaj Stanley; Ohba, Kenji; Yamamoto, Naoki

    2016-01-01

    The global Human Immunodeficiency Virus (HIV) pandemic is still spreading due to the lack of ideal anti-retroviral measures and their availability. Till date, all attempts to produce an efficient vaccine have ended with unsatisfactory results. The highly active anti-retroviral therapy (HAART) is the only effective weapon currently available and is widely being used for curtailing the HIV pandemic. However, the HAART is also expected to fail in the near future due to the emergence and dissemination of antiviral resistance. This review sheds light on the reasons for the failure of the conventional anti-viral measures against HIV and the novel anti-retroviral strategies currently being developed. The various principles to be considered for the success of a novel anti-retroviral strategy are elaborately emphasized and an innovative concept is proposed on these lines. The proposed concept intends to use receptor decoy traps (RDT) called cancellers which are erythrocytes expressing the HIV entry receptors on their surface. If successfully developed, the cancellers would be capable of active targeting of the free HIV particles leading to the trapping of the viruses within the canceller, resulting in the neutralization of infectivity of the trapped virus. The possible ways of translating this concept into reality and the probable hurdles that can be encountered in the process are subsequently discussed. Also, the scope of cancellers in therapeutic and/or preventive strategies against HIV infection is envisaged upon their successful development. PMID:25882216

    2011-10-01

    Full Text Available Background: Micronutrient supplementation has been shown to reduce the progression of HIV but does not have an effect on the intestinal barrier or the intestinal microbiota of HIV patients. Studies have suggested that probiotics could potentially complement micronutrients in preserving the immune-function of HIV patients. Objective: Assess the impact of micronutrient supplemented probiotic yogurt on the immune function of HIV patients. Design: We performed a randomized, double blind, controlled trial with CD4 count as primary outcome among HIV patients naïve to anti-retroviral treatment. Secondary outcomes included hematological parameters, incidence of diarrhea and clinical symptoms. A total of 112 HIV patients were randomized to receive a micronutrient fortified yogurt with (n = 55 or without additional probiotic Lactobacillus rhamnosus GR-1 (n = 57 for four weeks. Results: An average decline in CD4 count of −70 cells/μL (95% CI: −154 to −15 was observed in the micronutrient, probiotic group versus a decrease of −63 cells/μL (95% CI: −157 to −30 in the micronutrient control group (p = 0.9. Additional probiotic supplementation was well tolerated and not associated with adverse events. No difference between groups was detected in incidence of diarrhea or clinical symptoms. An improvement of hemoglobin levels was observed for all subjects, based upon a mean difference from baseline of 1.4 g/L (SD = 6 (p = 0.02. Conclusion: The addition of probiotics to a micronutrient fortified yogurt was well tolerated by HIV patients but was not associated with a further increase in CD4 count after one month.

  7. Effects of PPARγ and RBP4 gene variants on metabolic syndrome in HIV-infected patients with anti-retroviral therapy.

    Yuan-Pin Hung

    Full Text Available BACKGROUND: PPARγ and RBP4 are known to regulate lipid and glucose metabolism and insulin resistance. The influences of PPARγ (C1431T and Pro12Ala and RBP4 (-803GA polymorphisms on metabolic syndrome in HIV-infected patients receiving anti-retroviral therapy were examined in this study. MATERIALS AND METHODS: A cross-sectional study of HIV-1 infected adults with antiretroviral therapy for more than one year in the National Cheng Kung University Hospital was conducted. The gene polymorphisms were determined by quantitative PCR. RESULTS: Ninety-one patients were included in the study. Eighty-two (90.1% patients were males with a mean age of 44.4 years. For the C1431T polymorphism in PPARγ, while patients with the T allele (48.4% had trends toward lower rate of hypertriglyceridemia, the borderline significance together with insignificant power did not support the protective effect of the T allele against development of hypertriglyceridemia. For the Pro12Ala polymorphism in PPARγ, although patients with the Pro/Ala genotype (8.8% had a higher level of serum LDL (138.0 vs. 111.5 mg/dl, P = 0.04 and trends toward higher rates of hypercholesterolemia and serum LDL>110 mg/dl, these variables were found to be independent of the Pro/Ala genotype in the multivariate analysis. For the -803GA polymorphism in RBP4, patients with the A allele (23.1% more often had insulin resistance (HOMA>3.8; 33.3 vs. 8.7%, P = 0.01 and more often received anti-hypoglycemic drugs (14.3 vs. 1.4%, P = 0.04. The detrimental effect of the A allele in RBP4 -803GA polymorphism on development of insulin resistance was supported by the multivariate analysis adjusting for covariates. CONCLUSION: The impacts of PPARγ C1431T and Pro12Ala polymorphisms on metabolism in HIV-infected patients are not significant. RBP4 -803GA polymorphism has increased risk of insulin resistance in HIV-infected patients with anti-retroviral therapy.

    to have treatment failure retrospectively by the authors based on their records. Hence, they were not detected and these patients were not offered second line ARTs. Conclusions Having chronic malnutrition, low CD4 at base line, chronic diarrhea after initiation of first line ART, substitution of ART drugs and age less than 3 years old were found to be independent predictors of first line ART failure in children. Most of the first line ART failure cases were not detected early and those that were detected were not switched to second line drugs in a timely fashion. Children with the above risk factors should be closely monitored for a timely switch to second line highly active anti-retroviral therapy.

    Full Text Available Introduction & Objective: Oral lesions have important diagnostic and prognostic roles in HIV infected patients. It seems that HAART reduces the prevalence of oral lesions. The aim of the present study was to evaluate the prevalence of oral lesions in HIV infected patients on/not on HAART. Materials & Methods: In this retrospective study, 40 HIV infected patients receiving HAART and 40 who were not on HAART were evaluated in Behavioral Consultation Center in Kermanshah. The diagnosis of the oral lesions was recorded by using established presump-tive clinical criteria. Data were gathered and analyzed using SPSS version 16 by chi-square test. Results: In the current study 80 HIV infected patients with mean age of 38.86 were chosen. 72.5% and 27.5% of participants were male and female respectively. The most common le-sions in those receiving HAART were hairy leukoplakia, hairy tongue and oral pigmentation. However the prevalence of these lesions had declined in comparison to those who were not on HAART but the difference was not significant (P>0.05. Although comparing lesions in the two groups showed no significant difference, the total number of lesions significantly reduced in patients receiving HAART (P=0.046 Conclusion: According to the results of the present study using anti retroviral therapy leaded to reduction in the oral lesions in HIV infected patients. However, more research in this field seems necessary. (Sci J Hamadan Univ Med Sci 2013; 20 (3:215-222

    Full Text Available Abstract Background Little is known about the costs of HIV care in Ethiopia. Objective To estimate the average per person year (PPY cost of care for HIV patients with and without anti-retroviral therapy (ART in a district hospital. Methods Data on costs and utilization of HIV-related services were taken from Arba Minch Hospital (AMH in southern Ethiopia. Mean annual outpatient and inpatient costs and corresponding 95% confidence intervals (CI were calculated. We adopted a district hospital perspective and focused on hospital costs. Findings PPY average (95% CI costs under ART were US$235.44 (US$218.11–252.78 and US$29.44 (US$24.30–34.58 for outpatient and inpatient care, respectively. Estimates for the non-ART condition were US$38.12 (US$34.36–41.88 and US$80.88 (US$63.66–98.11 for outpatient and inpatient care, respectively. The major cost driver under the ART scheme was cost of ART drugs, whereas it was inpatient care and treatment in the non-ART scheme. Conclusion The cost profile of ART at a district hospital level may be useful in the planning and budgeting of implementing ART programs in Ethiopia. Further studies that focus on patient costs are warranted to capture all patterns of service use and relevant costs. Economic evaluations combining cost estimates with clinical outcomes would be useful for ranking of ART services.

  11. Retention of HIV-Infected Children in the First 12 Months of Anti-Retroviral Therapy and Predictors of Attrition in Resource Limited Settings: A Systematic Review

    Smith, Christiana; McFarland, Elizabeth J.

    2016-01-01

    Current UNAIDS goals aimed to end the AIDS epidemic set out to ensure that 90% of all people living with HIV know their status, 90% initiate and continue life-long anti-retroviral therapy (ART), and 90% achieve viral load suppression. In 2014 there were an estimated 2.6 million children under 15 years of age living with HIV, of which only one-third were receiving ART. Little literature exists describing retention of HIV-infected children in the first year on ART. We conducted a systematic search for English language publications reporting on retention of children with median age at ART initiation less than ten years in resource limited settings. The proportion of children retained in care on ART and predictors of attrition were identified. Twelve studies documented retention at one year ranging from 71–95% amongst 31877 African children. Among the 5558 children not retained, 4082 (73%) were reported as lost to follow up (LFU) and 1476 (27%) were confirmed to have died. No studies confirmed the outcomes of children LFU. Predictors of attrition included younger age, shorter duration of time on ART, and severe immunosuppression. In conclusion, significant attrition occurs in children in the first 12 months after ART initiation, the majority attributed to LFU, although true outcomes of children labeled as LFU are unknown. Focused efforts to ensure retention and minimize early mortality are needed as universal ART for children is scaled up. PMID:27280404

  14. Incubation periods under various anti-retroviral therapies in homogeneous mixing and age-structured dynamical models: A theoretical approach

    Rao, Arni S R Srinivasa

    2008-01-01

    Abstract. We consider previously well-known models in epidemiology where the parameter for incubation period is used as one of the important components to explain the dynamics of the variables. Such models are extended here to explain the dynamics with respect to a given therapy that prolongs the incubation period. A deconvolution method is demonstrated for estimation of parameters in the situations when no-therapy and multiple therapies are given to the infected population. The models and deconvolution method are extended in order to study the impact of therapy in age-structured populations. A generalisation for a situation when n-types of therapies are available is given.

    Full Text Available Objective: To learn the experiences of pregnant women with HIV/AIDS in relation to adherence to antiretroviral therapy in two public hospitals of reference for HIV/AIDS in Fortaleza-CE, Brazil. Methods: A descriptive study conducted with 24 pregnant women who were in prenatal care and use of antiretroviral therapy. Sociodemographic and obstetric data and information regarding the experience with antiretroviral therapy adherence were collected from July to September 2009, through a semi-structured interview. Results: Womenhad a mean age of 29, low income, low education and a stable partner. It was found that some factors affect pregnant women adherence to antiretroviral therapy. Among these, stand out not accepting the diagnosis and the absence of signs and symptoms of AIDS. However,the fear of transmitting the virus to the baby acted as a stimulus for pregnant women adhere to treatment. Conclusion: The non-acceptance of diagnosis and the absence of signs and symptoms of AIDS negatively affect pregnant women adherence to antiretroviral treatment. On the other hand, the fear that the child be born with the virus and the desire to continue to live are stimuli to adherence.

    In 2004, the Indian government began providing free antiretroviral therapy (ART) through established ART centers. Despite the fact that ART is provided free by the government, there are a large number of sero positive people who do not come forward to receive treatment. Non-adherence is further confounds efforts to offer effective treatment. This study reports the profile of patients who attend an ART centres in southern India.

  17. Use of anti-retroviral therapy in tuberculosis patients on second-line anti-TB regimens: a systematic review.

    Matthew Arentz

    Full Text Available INTRODUCTION: Use of antiretroviral therapy (ART during treatment of drug susceptible tuberculosis (TB improves survival. However, data from HIV infected individuals with drug resistant TB are lacking. Second line TB drugs when combined with ART may increase drug interactions and lead to higher rates of toxicity and greater noncompliance. This systematic review sought to determine the benefit of ART in the setting of second line drug therapy for drug resistant TB. METHODS: We included individual patient data from studies that evaluated treatment of drug-resistant tuberculosis in HIV-1 infected individuals published between January 1980 and December of 2009. We evaluated the effect of ART on treatment outcomes, time to smear and culture conversion, and adverse events. RESULTS: Ten observational studies, including data from 217 subjects, were analyzed. Patients using ART during TB treatment had increased likelihood of cure (hazard ratio (HR 3.4, 95% CI 1.6-7.4 and decreased likelihood of death (HR 0.4, 95% CI 0.3-0.6 during treatment for drug resistant TB. These associations remained significant in patients with a CD4 less than 200 cells/mm(3 and less than 50 cells/mm(3, and when correcting for drug resistance pattern. LIMITATIONS: We identified only observational studies from which individual patient data could be drawn. Limitations in study design, and heterogeneity in a number of the outcomes of interest had the potential to introduce bias. DISCUSSION: While there are insufficient data to determine if ART use increases adverse drug interactions when used with second line TB drugs, ART use during treatment of drug resistant TB appears to improve cure rates and decrease risk of death. All individuals with HIV appear to benefit from ART use during treatment for TB.

    Full Text Available Abstract Background The HIV and AIDS epidemic in Malawi poses multiple challenges from an equity perspective. It is estimated that 12% of Malawians are living with HIV or AIDS among the 15-49 age group. This paper synthesises available information to bring an equity lens on Counselling and Testing (CT and Antiretroviral Therapy (ART policy, practice and provision in Malawi. Methods A synthesis of a wide range of published and unpublished reports and studies using a variety of methodological approaches was undertaken. The analysis and recommendations were developed, through consultation with key stakeholders in Malawi. Findings At the policy level Malawi is unique in having an equity in access to ART policy, and equity considerations are also included in key CT documents. The number of people accessing CT has increased considerably from 149,540 in 2002 to 482,364 in 2005. There is urban bias in provision of CT and more women than men access CT. ART has been provided free since June 2004 and scale up of ART provision is gathering pace. By end December 2006, there were 85,168 patients who had ever started on ART in both the public and private health sector, 39% of the patients were male while 61% were female. The majority of patients were adults, and 7% were children, aged 14 years or below. Despite free ART services, patients, especially poor rural patients face significant barriers in access and adherence to services. There are missed opportunities in strengthening integration between CT and ART and TB, Sexually Transmitted Infections (STI and maternal health services. Conclusion To promote equitable access for CT and ART in Malawi there is need to further invest in human resources for health, and seize opportunities to integrate CT and ART services with tuberculosis, sexually transmitted infections and maternal health services. This should not only promote access to services but also ensure that resources available for CT and ART strengthen

    Full Text Available Abstract Background The tuberculosis (TB and human immunodeficiency virus (HIV epidemics are poorly controlled in sub-Saharan Africa, where highly active antiretroviral treatment (HAART has become more freely available. Little is known about the clinical presentation and outcome of TB in HIV-infected children on HAART. Methods We performed a comprehensive file review of all children who commenced HAART at Tygerberg Children's Hospital from January 2003 through December 2005. Results Data from 290 children were analyzed; 137 TB episodes were recorded in 136 children; 116 episodes occurred before and 21 after HAART initiation; 10 episodes were probably related to immune reconstitution inflammatory syndrome (IRIS. The number of TB cases per 100 patient years were 53.3 during the 9 months prior to HAART initiation, and 6.4 during post HAART follow-up [odds ratio (OR 16.6; 95% confidence interval (CI 12.5–22.4]. A positive outcome was achieved in 97/137 (71% episodes, 6 (4% cases experienced no improvement, 16 (12% died and the outcome could not be established in 18 (13%. Mortality was less in children on HAART (1/21; 4.8% compared to those not on HAART (15/116; 12.9%. Conclusion We recorded an extremely high incidence of TB among HIV-infected children, especially prior to HAART initiation. Starting HAART at an earlier stage is likely to reduce morbidity and mortality related to TB, particularly in TB-endemic areas. Management frequently deviated from standard guidelines, but outcomes in general were good.

    HIV-1 Nef, a critical AIDS progression factor, represents an important target protein for antiretroviral drug discovery. Because Nef lacks intrinsic enzymatic activity, we developed an assay that couples Nef to the activation of Hck, a Src-family member and Nef effector protein. Using this assay, we screened a large, diverse chemical library and identified small molecules that block Nef-dependent Hck activity with low micromolar potency. Of these, a diphenylpyrazolo compound demonstrated sub-...

    Objective To evaluate the impact of HIV co-infection with HCV or HBV on the efficacy of highly active anti-retroviral therapy (HARRT). Methods The patients were divided into three groups: HIV + HBV + HCV co-infection group ( 23 patients), HIV + HCV co-infection group ( 166 patients), and HIV-only group (178 patients). HIV RNA, HCV RNA or HBV DNA were detected by real time PCR before treatment and 1,3,6,9 and 12 monthes after treatment, meanwhile the counts of CD4+ T lymphocyte and liver function including ALT, AST and TBil were tested. Results During one-year HAART, HIV RNA of HIV-only group, HIV + HBV + HCV co-infection group and HIV + HCV co-infection group decreased significantly from (6.78 ± 1.08), (6.23 ± 1.34), (6.54 ± 1.23) lg copies/ml to (0.53 ±0.15), (0.67 ±0.16),(0.43 ±0.11 ) lg copies/ml respectively (P<.001 ). And CD4+ T lymphocyte counts of the three groups elevated significantly from ( 197 ± 127), (184 ± 113), (213 ± 143) cells/μl to (382 ±74), (383 ±70),(378 ±76) cells/μl respectively (P <0.001 ). However there were no differences among the three groups in HIV RNA and CD4+ T lymphocyte counts. There were no differences in liver functions including ALT,AST and TBil among the three groups. Conclusiom HIV co-infected with HBV and/or HCV does not impact on the efficacy of HAART. What more, HAART does not impact HCV replication.%目的 观察HIV感染者合并HCV和HBV感染后对高效抗逆转录病毒治疗(HAART)疗效的影响.方法 对某地区HIV、HCV共感染患者166例(HIV+HCV组),HIV、HCV和HBV混合感染患者23例(H1V+HCV+HBV组)及单纯HIV感染者178例,给予1年的HAART治疗,观察3组患者病毒学反应、免疫学反应和肝功能动态变化.以流式细胞仪检测外周血CD4+T淋巴细胞;实时PCR定量检测HCV、HIV和HBV病毒载量.结果 单纯HIV感染组、HIV+HCV+HBV组和HIV+HCV组经HAART 1年后,HIV病毒载量分别由治疗前(6.78±1.08)、(6.23±1.34)、(6.54±1.23)lg拷贝/ml下降至(0

METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cross-sectional analysis was performed on routine program data for the period of February 2003 to July 2004. Standardized registers and patient cards were used to gather data. The place of residence was used to determine road distances to the Thyolo district hospital. Cost of transport from different parts of the district was based on the known cost for public transport to the road-stop closest to the patient's residence. Of 1,290 newly registered TB patients, 1,003(78% underwent HIV-testing of whom 770 (77% were HIV-positive. 742 of these individuals (pulmonary TB = 607; extra-pulmonary TB = 135 were considered eligible for ART of whom only 101(13.6% accepted ART. Cost of transport to the hospital ART site was significantly associated with ART acceptance and there was a linear trend in association between cost and ART acceptance (chi(2 for trend = 25.4, P<0.001. Individuals who had to pay 50 Malawi Kwacha (1 United States Dollar = 100 Malawi Kwacha, MW or less for a one-way trip to the Thyolo hospital were four times more likely to accept ART than those who had to pay over 100 MW (Adjusted Odds ratio = 4.0, 95% confidence interval: 2.0-8.1, P<0.001. CONCLUSIONS/SIGNIFICANCE: ART acceptance among TB patients in a rural district in Malawi is low and associated with cost of transport to the centralized hospital based ART site. Decentralizing the ART offer from the hospital to health centers that are closer to home communities would be an essential step towards reducing the overall cost and burden of travel.

    Anti-retroviral drug resistance evolves as an inevitable consequence of expanded combination Anti-retroviral Therapy (cART). According to each drug class, resistance mutations may occur due to the infidel nature of HIV reverse transcriptase (RT) and inadequate drug pressures. Correspondingly, resistance to Nucleoside Reverse Transcriptase Inhibitors (NRTIs) occurs due to incorporation impairment of the agent or its removal from the elongating viral DNA chain. With regard to Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs), resistance mutations may alter residues of the RT hydrophobic pocket and demonstrate high level of cross resistance. However, resistance to Protease Inhibitors requires complex accumulation of primary and secondary mutations that substitute amino acids in proximity to the viral protease active site. Resistance to novel entry inhibitors may also evolve as a result of mutations that affect the interactions between viral glycoprotein and CD4 or the chemokine receptors. According to the current studies, future drug initiative programs should consider agents that possess higher genetic barrier toward resistance for ascertaining adequate drug efficacy among patients who have failed first-line regimens.

    CD4⁺ T-lymphocyte destruction, microbial translocation, and systemic immune activation are the main mechanisms of the pathogenesis of human immunodeficiency virus type 1 (HIV) infection. To investigate the impact of HIV infection and antiretroviral therapy (ART) on the immune profile of and microbial translocation in HIV-infected children, 60 HIV vertically infected children (31 without ART: HIV(+) and 29 with ART: ART(+)) and 20 HIV-uninfected children (HIV(-)) aged 2-12 years were recruited in Vietnam, and their blood samples were immunologically and bacteriologically analyzed. Among the HIV(+) children, the total CD4⁺-cell and their subset (type 1 helper T-cell (Th1)/Th2/Th17) counts were inversely correlated with age (all p HIV(-) children by the age of 2 years; the CD4/CD8 ratio was inversely correlated with the plasma HIV RNA load and CD8⁺-cell activation status. Among the ART(+) children, the total CD4⁺-cell and Th2/Th17/Treg-subset counts and the CD4/CD8 ratio gradually increased, with estimated ART periods of normalization being 4.8-8.3 years, whereas Th1 counts and the CD8⁺-cell activation status normalized within 1 year of ART initiation. sCD14 levels remained high even after ART initiation. The detection frequency of bacterial 16S/23S ribosomal DNA/RNA in blood did not differ between HIV-infected and -uninfected children. Thus, in children, HIV infection caused a rapid decrease in Treg counts and the early activation of CD8⁺ cells and monocytes, and ART induced rapid Th1 recovery and early CD8⁺-cell activation normalization but had little effect on monocyte activation. The CD4/CD8 ratio could therefore be an additional marker for ART monitoring. PMID:27490536

  12. Retinal arterioles narrow with increasing duration of anti-retroviral therapy in HIV infection: a novel estimator of vascular risk in HIV?

    Sophia Pathai

    Full Text Available OBJECTIVES: HIV infection is associated with an increased risk of age-related morbidity mediated by immune dysfunction, atherosclerosis and inflammation. Changes in retinal vessel calibre may reflect cumulative structural damage arising from these mechanisms. The relationship of retinal vessel calibre with clinical and demographic characteristics was investigated in a population of HIV-infected individuals in South Africa. METHODS: Case-control study of 491 adults ≥30 years, composed of 242 HIV-infected adults and 249 age- and gender-matched HIV-negative controls. Retinal vessel calibre was measured using computer-assisted techniques to determine mean arteriolar and venular diameters of each eye. RESULTS: The median age was 40 years (IQR: 35-48 years. Among HIV-infected adults, 87.1% were receiving highly active antiretroviral therapy (HAART (median duration, 58 months, their median CD4 count was 468 cells/µL, and 84.3% had undetectable plasma viral load. Unadjusted mean retinal arteriolar diameters were 163.67±17.69 µm in cases and 161.34±17.38 µm in controls (p = 0.15. Unadjusted mean venular diameters were 267.77±18.21 µm in cases and 270.81±18.98 µm in controls (p = 0.07. Age modified the effect of retinal arteriolar and venular diameters in relation to HIV status, with a tendency towards narrower retinal diameters in HIV cases but not in controls. Among cases, retinal arteriolar diameters narrowed with increasing duration of HAART, independently of age (167.83 µm 6 years, p-trend = 0.02, and with a HIV viral load >10,000 copies/mL while on HAART (p = 0.05. HIV-related venular changes were not detected. CONCLUSIONS: Narrowing of retinal arteriolar diameters is associated with HAART duration and viral load, and may reflect heightened inflammatory and pro-atherogenic states of the systemic vasculature. Measurement of retinal vascular calibre could be an innovative non-invasive method of estimating vascular risk in HIV

    Full Text Available Objective: To learn the experiences of pregnant women with HIV/AIDS in relation to adherence to antiretroviral therapy in two public hospitals of reference for HIV/AIDS in Fortaleza-CE, Brazil. Methods: A descriptive study conducted with 24 pregnant women who were in prenatal care and use of antiretroviral therapy. Sociodemographic and obstetric data and information regarding the experience with antiretroviral therapy adherence were collected from July to September 2009, through a semi-structured interview. Results: Women had a mean age of 29, low income, low education and a stable partner. It was found that some factors affect pregnant women adherence to antiretroviral therapy. Among these, stand out not accepting the diagnosis and the absence of signs and symptoms of AIDS. However, the fear of transmitting the virus to the baby acted as a stimulus for pregnant women adhere to treatment. Conclusion: The non-acceptance of diagnosis and the absence of signs and symptoms of AIDS negatively affect pregnant women adherence to antiretroviral treatment. On the other hand, the fear that the child be born with the virus and the desire to continue to live are stimuli to adherence.

  14. Atividade anti-retroviral e propriedades farmacocinéticas da associação entre lamivudina e zidovudina Antiretroviral activity and pharmacokinetics properties of lamivudine and zidovudine association

    Jacqueline de Souza

    2004-03-01

    Full Text Available A lamivudina (3TC e a zidovudina (ZDV são agentes anti-retrovirais indicados para o tratamento de infecção pelo HIV. Eles são análogos nucleosídeos, que passam por reações intracelulares de fosforilação e atuam inibindo a enzima transcriptase reversa. Os compostos trifosforilados formados se ligam à cadeia de DNA pró-viral impedindo sua replicação. A terapêutica anti-retroviral utilizando apenas um fármaco ocasiona, freqüentemente, a seleção de cepas resistentes. Os efeitos adversos provocados pela ZDV são mais comuns em pacientes com doença em estágio avançado, sendo o principal deles a mielossupressão. A 3TC é bem tolerada, mas sua toxicidade aumenta proporcionalmente ao acréscimo da dose. Quanto à farmacocinética, ambos são facilmente absorvidos passivamente e biotransformados em compostos ativos trifosforilados. Eles são amplamente distribuídos, penetram livremente nos tecidos a partir da circulação sistêmica. Difundem-se através da placenta da circulação materna para a circulação fetal. O principal caminho metabólico da ZDV é a glicuronidação, cerca de 60 a 70% do fármaco é inativado por essa via. Ela é eliminada rapidamente, sendo sua meia-vida de eliminação da ordem de 1 a 1,5 h. Apenas 5% a 10% da 3TC são biotransformados em um metabólito trans-sulfóxido inativo. Sua meia-vida de eliminação é de 8,5 a 11,5 h, sendo que 70% do fármaco são excretados de forma inalterada na urina até 24 h após a dose.Lamivudine (3TC and zidovudine (ZDV are antiretroviral drugs used in the treatment of HIV infection. They are nucleoside analogues that inhibit HIV-1 reverse transcriptase. These drugs are anabolized intracellularly by a stepwise process and form an active triphosphate anabolite, which is used by HIV-1 reverse transcriptase and effectively terminates chain extension. The use of monotherapy is associated with a delay in the emergence of resistant mutants. The combination therapy would

    Full Text Available Brazil provides free antiretroviral (ARV therapy to some 150,000 individuals living with HIV/ AIDS. ARV regimens require optimal adherence to achieve undetectable viral loads and to avoid viral resistance. Physicians play a key role to foster ARV adherence, but until now little is known about the communication between physicians/ people living with HIV/AIDS in this setting. In-depth interviews were conducted with 40 physicians treating people living with HIV/AIDS at six public reference centers in Rio de Janeiro, Brazil. Interview topics included: experiences in the treatment of people living with HIV/AIDS, relationship and dialogue with patients, barriers/facilitators to adherence, and effectiveness of available services. Barriers to ARV adherence were mainly related to the low quality of patient-provider relationship. Other barriers were related to "chaotic" patients' lifestyles, and inadequate knowledge and/or negative beliefs about HIV/AIDS and ARV effectiveness. It is necessary to improve networking between services, establish agile referral systems, and improve health professionals' integration. These structural changes could contribute to improved adherence, resulting in improved quality of life for people living with HIV/AIDS.O Brasil fornece gratuitamente terapia anti-retroviral (ARV para cerca de 150 mil pessoas vivendo com HIV/ AIDS.

    The survival time of HIV/AIDS patients in Korea has increased since HAART (highly active anti-retroviral therapy) was introduced. However, the occurrence of drug-resistant strains requires new anti-retroviral drugs, one of which, an integrase inhibitor (INI), was approved by the US Food and Drug Administration (FDA) in 2007. INIs have been used for therapy in many countries and are about to be employed in Korea. Therefore, it is important to identify basic mutant variants prior to the introduction of INIs in order to estimate their efficacy. To monitor potential drug-resistant INI mutations in Korean HIV/AIDS patients, the polymorphism of the int gene was investigated together with the pol gene using a genotypic assay for 75 randomly selected Korean HIV-1 patients newly diagnosed in 2007. The drug-resistant mutation sequences were analysed using the Stanford HIV DB and the International AIDS Society resistance testing-USA panel (IAS-USA). Seventy strains of Korean subtype B were compared with foreign subtype-B strains, and there were no significantly different variants of the int gene region in the study population. Major mutation sites in the integrase (E92Q, F121Y, G140A/S, Y143C/R, Q148H/R/K and N155H) were not detected, and only a few minor mutation sites (L74M, V151I, E157Q, V165I, I203M, S230N and D232N) were identified in 21 strains (28%). Resistance due to mutations in the pol gene was observed in a single strain (1.3%) resistant to protease inhibitors (PIs) and in four strains (5.3%) resistant to reverse transcriptase inhibitors (RTIs). In summary, this demonstrates that INIs will be susceptible to drug naïve HIV/AIDS patients in Korea. PMID:20946407

Estudo de corte transversal com pacientes de dois serviços públicos de referência (n = 310 em Belo Horizonte, Minas Gerais, Brasil. Atraso no início da TARV foi definido como ter contagem de linfócitos T CD4+ The main objective was to assess the proportion of delayed initiation of antiretroviral therapy (ART and associated factors. This was a cross-sectional study of 310 patients enrolled in two public health centers in Belo Horizonte, Minas Gerais State, Brazil. Delayed ART initiation was defined as starting treatment with a CD4 count lower than 200 cells/mm³ or clinical symptoms of severe immunodepression at the time of first antiretroviral prescription. The majority of participants were males (63.9%, had no health insurance (76.1%, and started ART less than 120 days after the first medical visit (75.2%. The proportion of delayed ART initiation was 68.4%. Unemployment, referral by a health professional for HIV testing, fewer than two medical visits in the six months prior to ART initiation, and time between first medical visit and ART initiation less than 120 days were independently associated with the outcome. Our results suggest that every patient 13 to 64 years of age should be offered HIV testing, which could increase the rate of early HIV diagnosis, and thus patients that tested positive could benefit from timely follow-up and antiretroviral therapy.

The groups concluded that the pharmacy has an important role in the antiretroviral drug supply, which is reflected in the treatment adherence, because trust-based relationships can be built up through their procedures. In spite of this, they pointed out that such building-up does not take place through excessively bureaucratic activities. This has negative repercussions for all patients, especially for injecting drug users, considered "difficult people". Such concept sums up their behavior: they are supposed to be confused and incapable to adhere to treatment, and have limited understanding. Staff members, however, affirm they treat these patients equally. They do not realize that, by this acting, the specific needs of injecting drug users may become invisible in the service. There is also the possibility that stigmatizing stereotypes may be created, resulting in yet another barrier to the work on adherence. CONCLUSIONS: Although the pharmacy is recommended as a potentially favorable place to listen to and form bonds with users, the results show objective and subjective obstacles to render it suitable for the work on adherence.

    Full Text Available Non-adherence is one of the primary obstacles to successful antiretroviral therapy in HIV+ patients worldwide. In Brazil, the Domiciliary Therapeutic Assistance is a multidisciplinary and integrated home-based assistance program provided for HIV+ patients confined in their homes due to physical deficiency. This study investigated ADT's ability to monitor and promote appropriate adherence to ARV therapy. Fifty-six individuals were recruited from three study groups: Group 1 - patients currently in the ADT program, Group 2 - 21 patients previously treated by the ADT program, and Group 3 - 20 patients who have always been treated using conventional ambulatory care. Using multivariable self-reporting to evaluate adherence, patients in the ADT program had significantly better adherence than patients in ambulatory care (F = 6.66, p = 0.003. This effect was independent of demographic and socioeconomic characteristics as well as medical history. Patients in the ADT program also showed a trend towards greater therapeutic success than ambulatory patients. These results suggest the incorporation of characteristics of ADT in conventional ambulatory care as a strategy to increase adherence to ARV therapy.O sucesso da terapia antiretroviral depende da adesão ao tratamento. A Assistência Domiciliar Terapêutica é um programa de atendimento multidisciplinar a pacientes com HIV/AIDS e com dificuldades de se deslocar para atendimento ambulatorial. Este estudo compara a adesão de pacientes ao esquema ARV em um programa ADT com aqueles em tratamento ambulatorial convencional. Foram estudados: Grupo 1 - 15 pacientes no programa de ADT, Grupo 2 - 21 pacientes em tratamento ambulatorial convencional, Grupo 3 - 20 pacientes em tratamento ambulatorial convencional que nunca freqüentaram o programa ADT. Os pacientes inscritos no programa ADT apresentaram significativamente maior adesão ao tratamento do que pacientes ambulatoriais (F = 6.66, p= 0,003. Os resultados

    Full Text Available Neste trabalho, utilizaram-se os algoritmos EM e EMS aplicados ao método do Cálculo Retroativo para estimar a magnitude da epidemia do HIV no Brasil. Fazendo-se suposições a respeito do comportamento dos infectados, em relação à utilização da terapia combinada das drogas anti-retrovirais, construíram-se cinco cenários para a epidemia brasileira. O objetivo foi o de ilustrar os impactos que a utilização da terapia combinada das drogas anti-retrovirais possam estar tendo ou possam vir a ter na incubação do vírus e, por conseguinte, nas avaliações da epidemia realizadas a partir dos casos de Aids notificados.We applied the back-calculation method to estimate the magnitude of the HIV epidemic in Brazil, using the EM and EMS algorithms. Under certain assumptions regarding the behavior of infected patients towards combined antiretroviral therapy, we discuss five different scenarios applied to the Brazilian epidemic. Our objective was to illustrate the impact of combined antiretroviral treatment on the incubation period and thus on estimates of the size of the HIV-infected population, based on reported AIDS cases.

  9. IL-1Β enriched monocytes mount massive IL-6 responses to common inflammatory triggers among chronically HIV-1 infected adults on stable anti-retroviral therapy at risk for cardiovascular disease.

    Emilie Jalbert

    Full Text Available Chronic infection by HIV increases the risk of cardiovascular disease (CVD despite effective antiretroviral therapy (ART. The mechanisms linking HIV to CVD have yet to be fully elucidated. High plasma levels of the pro-inflammatory cytokine IL-6, which may be triggered by IL-1β, is a biomarker of CVD risk in HIV-negative adults, and of all-cause mortality in HIV disease. Monocytes play a pivotal role in atherosclerosis, and may be major mediators of HIV-associated inflammation. We therefore hypothesized that monocytes from HIV-infected adults would display high inflammatory responses. Employing a 10-color flow cytometry intracellular cytokine staining assay, we directly assessed cytokine and chemokine responses of monocytes from the cryopreserved peripheral blood of 33 chronically HIV-1 infected subjects. Participants were 45 years or older, on virologically suppressive ART and at risk for CVD. This group was compared to 14 HIV-negative subjects matched for age and gender, with similar CVD risk. We simultaneously detected intracellular expression of IL-1β, IL-6, IL-8 and TNF in blood monocytes in the basal state and after stimulation by triggers commonly found in the blood of treated, chronically HIV-infected subjects: lipopolysaccharide (LPS and oxidized low-density lipoprotein (oxLDL. In the absence of stimulation, monocytes from treated HIV-infected subjects displayed a high frequency of cells producing IL-1β (median 19.5%, compared to low levels in HIV-uninfected persons (0.9% p<0.0001. IL-8, which is induced by IL-1β, was also highly expressed in the HIV-infected group in the absence of stimulation, 43.7% compared to 1.9% in HIV-uninfected subjects, p<0.0001. Strikingly, high basal expression of IL-1β by monocytes predicted high IL-6 levels in the plasma, and high monocyte IL-6 responses in HIV-infected subjects. Hyper-inflammatory IL-1β enriched monocytes may be a major source of IL-6 production and systemic inflammation in HIV

  11. The effects of decentralizing anti-retroviral services in Nigeria on costs and service utilization: two case studies.

    Johns, Benjamin; Baruwa, Elaine

    2016-03-01

    Nigeria launched a 'hub and spoke' decentralization pilot in March 2010 for the provision of anti-retroviral therapy (ART). In this programme, stable ART patients at hospitals (hubs) were referred to primary health care centres (spokes) for the continued provision of ART. The objectives of this study are to compare the cost of ART care provided through the two levels of care. We also assess if decentralization was associated with changes in patients' service utilization. Data were collected from facilities and patient records from Kaduna and Cross Rivers States. Costs were collected from the provider perspective. In Cross River, 398 patients and 528 from Kaduna were included in the retrospective cohort. The analysis utilizes separate fixed effect regressions for each state to assess differences in costs and service utilization among patients that decentralized. Uptake of decentralized services was ∼3% in Cross Rivers and ∼9% in Kaduna among active ART patients in April 2011. Patients electing to decentralize had 40% (95% CI: 13% to 67%) higher costs in Cross Rivers and 29% (-44% to -14%) lower costs in Kaduna as compared with patients that did not decentralize. Lower costs in Kaduna appear to result from shifting care to less expensive cadres of health workers (task shifting) rather than decentralization. Decentralization of health services is a complicated process and broad generalizations across settings and processes, concerning whether or not it reduces unit costs, are likely over-simplifications. Similarly, decentralization of ART services does not automatically increase access to ART care, and may limit access to ART laboratory services. This study is limited by not including costs incurred above the facility level, such as training, or costs borne by patients. PMID:25989806

Methods Participants were 532 HIV infected patients, 51 children and 481 adults, 165 males and 367 females. Children were aged 2–17 years and adults 18 and 67 years. Participants were recruited consecutively at the Muhimbili National Hospital (MNH HIV clinic from October 2004 to September 2005. Investigations included; interviews, physical examinations, HIV testing and enumeration of CD4+ T cells. Results A total of 237 HIV-associated oral lesions were observed in 210 (39.5% patients. Oral candidiasis was the commonest (23.5%, followed by mucosal hyperpigmentation (4.7%. There was a significant difference in the occurrence of oral candidiasis (χ2 = 4.31; df = 1; p = 0.03 and parotid enlargement (χ2 = 36.5; df = 1; p = 0.04 between children and adults. Adult patients who were on HAART had a significantly lower risk of; oral lesions (OR = 0.32; 95% CI = 0.22 – 0.47; p = 0.005, oral candidiasis (OR = 0.28; 95% CI = 0.18 – 0.44; p = 0.003 and oral hairy leukoplakia (OR = 0.18; 95% CI = 0.04 – 0.85; p = 0.03. There was no significant reduction in occurrence of oral lesions in children on HAART (OR = 0.35; 95% CI = 0.11–1.14; p = 0.15. There was also a significant association between the presence of oral lesions and CD4+ cell count 3 (χ2 = 52.4; df = 2; p = 0.006 and with WHO clinical stage (χ2 = 121; df = 3; p = 0.008. Oral lesions were also associated with tobacco smoking (χ2 = 8.17; df = 2; p = 0.04. Conclusion Adult patients receiving HAART had a significantly lower prevalence of oral lesions, particularly oral candidiasis and oral hairy leukoplakia. There was no significant change in occurrence of oral lesions in children receiving HAART. The occurrence of oral lesions, in both HAART and non-HAART patients, correlated with WHO clinical staging and CD4+ less than 200 cells/mm3.

  18. The occurrence of anti-retroviral compounds used for HIV treatment in South African surface water

    The study and quantification of personal care products, such as pharmaceuticals, in surface water has become popular in recent years; yet very little description of these compounds’ presence in South African surface water exists in the literature. Antiretrovirals (ARVs), used to treat human immunodeficiency virus (HIV) are rarely considered within this field. A new method for the simultaneous quantification of 12 antiretroviral compounds in surface water using the standard addition method is described. Water samples were concentrated by a generic automated solid phase extraction method and analysed by ultra-high pressure liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). Substantial matrix effect was encountered in the samples with an average method detection limit of 90.4 ng/L. This is the first reported countrywide survey of South African surface water for the quantification of these compounds with average concentrations ranging between 26.5 and 430 ng/L. - Highlights: • An LC-MS/MS method for the detection of 12 antiretroviral drugs was developed. • The compounds were detected in South African surface water for the first time. • Targets occurred in the low to mid ng/L range. • Nevirapine occurred ubiquitously across all the samples tested. • Matrix effect was corrected for using a modified standard addition method. - This work represents the first quantitative description of anti-retrovirals, as a group, in surface water using a modified standard addition method and UHPLC-MS/MS

  19. Perinatal genotoxicity and carcinogenicity of anti-retroviral nucleoside analog drugs

    The current worldwide spread of the human immunodeficiency virus-1 (HIV-1) to the heterosexual population has resulted in approximately 800 000 children born yearly to HIV-1-infected mothers. In the absence of anti-retroviral intervention, about 25% of the approximately 7000 children born yearly to HIV-1-infected women in the United States are HIV-1 infected. Administration of zidovudine (AZT) prophylaxis during pregnancy reduces the rate of infant HIV-1 infection to approximately 7%, and further reductions are achieved with the addition of lamivudine (3TC) in the clinical formulation Combivir. Whereas clinically this is a remarkable achievement, AZT and 3TC are DNA replication chain terminators known to induce various types of genotoxicity. Studies in rodents have demonstrated AZT-DNA incorporation, HPRT mutagenesis, telomere shortening, and tumorigenicity in organs of fetal mice exposed transplacentally to AZT. In monkeys, both AZT and 3TC become incorporated into the DNA from multiple fetal organs taken at birth after administration of human-equivalent protocols to pregnant dams during gestation, and telomere shortening has been found in monkey fetuses exposed to both drugs. In human infants, AZT-DNA and 3TC-DNA incorporation as well as HPRT and GPA mutagenesis have been documented in cord blood from infants exposed in utero to Combivir. In infants of mice, monkeys, and humans, levels of AZT-DNA incorporation were remarkably similar, and in newborn mice and humans, mutation frequencies were also very similar. Given the risk-benefit ratio, these highly successful drugs will continue to be used for prevention of vertical viral transmission, however evidence of genotoxicity in mouse and monkey models and in the infants themselves would suggest that exposed children should be followed well past adolescence for early detection of potential cancer hazard

This study was conducted to determine if alternate treatment options may meet the needs of both general and special patient populations. The ACTION study was a randomized, open-label, multicenter, 48-week trial that compared the safety and efficacy of a triple nucleoside regimen versus a protease inhibitor plus a dual nucleoside regimen in HIV-1 treatment-naïve subjects. Results 279 HIV-infected subjects with HIV-1 RNA (VL >5000 but 3 were randomized (1:1 to receive abacavir sulfate/lamivudine/zidovudine (ABC/3TC/ZDV twice-daily or atazanavir (ATV once-daily plus lamivudine/zidovudine (3TC/ZDV twice-daily. Protocol-defined virologic failure was based on multiple failure criteria. Non-inferiority of ABC/3TC/ZDV to ATV+3TC/ZDV was established with 62% vs. 59% of subjects achieving a VL Conclusion ABC/3TC/ZDV demonstrated comparable virologic efficacy to ATV+3TC/ZDV in this population over 48 weeks. In those with a baseline VL ≥ 100,000 c/mL, subjects in the ATV+3TC/ZDV showed better virologic efficacy. Both regimens offer benefits in select therapy-naïve subjects.

    The human immunodeficiency virus (HIV) can be suppressed by highly active anti-retroviral therapy (HAART) in the majority of infected patients. Nevertheless, treatment interruptions inevitably result in viral rebounds from persistent, latently infected cells, necessitating lifelong treatment. Virological failure due to resistance development is a frequent event and the major threat to treatment success. Currently, it is recommended to change treatment after the confirmation of virological fai...

    Full Text Available Summary: Alka-Vita™/Alka-V6™/Alkahydroxy™ (AVAH, a modified sodium silicate dietary supplement manufactured by Cisne Enterprises Inc. (Odessa, TX was evaluated for its in vitro anti-retroviral and anti-pathogenic effects. Effects on nitric oxide (NO dependent antiviral activities were measured in neutrophils using standard assays. Assays for inhibition of HIV-II reverse transcriptase (RT, HIV-II protease (PR and glucohydrolase [glucuronidase (GH-1 and glucosidase (GH-2] important for viral replication, coat assembly and virulence respectively, were performed using standard kits. Higher NO (~ 2 fold was detected in neutrophil medium indicating an increase NO mediated antipathogeic activity. Results suggest that the product significantly decreased HIV-RT activity in a dose dependent manner (ED50= 20.4 mM. HIV-PR activity decreased (IC50=14.6 mM with increasing product concentration. The product also decreased the HIV-II virulence by inhibiting the GH-1 (IC50= 34.29 mM and GH-2 (IC50=14.6 mM activity which decreased protein glucosylation and glucuronylation. Changes in surface EPS carbohydrates assed in Pseudomonas aeruginosa suggested a modulatory effect on various carbohydrates and therefore the composition of EPS. Industrial relevance: Pathologies caused by retroviral agents and microorganisms are prevalent both in developed and developing countries.  Indiscriminate use of single target medical drugs has resulted in the development of resistance in these pathogens. Development of novel therapeutic  agents that can effect multiple intrinsic and extrinsic targets in host and the pathogen may prove to be more effective and are less likely to promote drug induced selection. The effectiveness of Alka-Vita™/Alka-V6™/Alkahydroxy™ (AVAH in mitigating various virulence and survival pathways in pathogens is promising. Additionally, it was also effective in inducing a NO mediated immune response.

    alterations are characterized by elevated levels of tumor necrosis factor alpha (TNF-α, interleukin 8 (IL-8, β2-microglobulin, IgA, IgG, IgM, haptoglobin and a1-acid glycoprotein. The goal of this double blind placebo-controlled study was to evaluate the effect of N-acetylcysteine supplementation on virological, immunological and inflammatory markers in 24 HIVinfected individuals who were taking their first anti-retroviral therapy. Eleven individuals were treated with anti-retroviral therapy plus placebo supplementation and thirteen were treated with anti-retroviral therapy plus 600 mg/day of Nacetylcysteine. The levels of the studied markers were evaluated at the day before and after 60, 120 and 180 days of treatment. In both groups a significant decrease in serum levels of TNF-α (p=0.0001, IL-6 (p>0.05, IL-8 (p=0.0001, b2 microglobulin (p=0.0005, IgA (p=0.007, IgG (p=0.001, IgM (p=0.0001, haptoglobin (p=0.0001 e α1-acid glycoprotein (p=0.012 was found due to anti-retroviral therapy. N-acetylcysteine supplementation had no additive or synergistic effects on the studied parameters. In conclusion, N-acetylcysteine had no additional beneficial effects, at least at the dose used in this study, on the treatment of HIV-infected patients under anti-retroviral therapy.

  15. Neutralizing antibody and anti-retroviral drug sensitivities of HIV-1 isolates resistant to small molecule CCR5 inhibitors

    The small molecule CCR5 inhibitors are a new class of drugs for treating infection by human immunodeficiency virus type 1 (HIV-1). They act by binding to the CCR5 co-receptor and preventing its use during HIV-1-cell fusion. Escape mutants can be raised against CCR5 inhibitors in vitro and will arise when these drugs are used clinically. Here, we have assessed the responses of CCR5 inhibitor-resistant viruses to other anti-retroviral drugs that act by different mechanisms, and their sensitivities to neutralizing antibodies (NAbs). The rationale for the latter study is that the resistance pathway for CCR5 inhibitors involves changes in the HIV-1 envelope glycoproteins (Env), which are also targets for NAbs. The escape mutants CC101.19 and D1/85.16 were selected for resistance to AD101 and vicriviroc (VVC), respectively, from the primary R5 HIV-1 isolate CC1/85. Each escape mutant was cross-resistant to other small molecule CCR5 inhibitors (aplaviroc, maraviroc, VVC, AD101 and CMPD 167), but sensitive to protein ligands of CCR5: the modified chemokine PSC-RANTES and the humanized MAb PRO-140. The resistant viruses also retained wild-type sensitivity to the nucleoside reverse transcriptase inhibitor (RTI) zidovudine, the non-nucleoside RTI nevirapine, the protease inhibitor atazanavir and other attachment and fusion inhibitors that act independently of CCR5 (BMS-806, PRO-542 and enfuvirtide). Of note is that the escape mutants were more sensitive than the parental CC1/85 isolate to a subset of neutralizing monoclonal antibodies and to some sera from HIV-1-infected people, implying that sequence changes in Env that confer resistance to CCR5 inhibitors can increase the accessibility of some NAb epitopes. The need to preserve NAb resistance may therefore be a constraint upon how escape from CCR5 inhibitors occurs in vivo

  16. Anti-retroviral treatment outcomes among older adults in Zomba district, Malawi.

    Joel Negin

    Full Text Available BACKGROUND: There are approximately 3 million people aged 50 and older in sub-Saharan Africa who are HIV-positive. Despite this, little is known about the characteristics of older adults who are on treatment and their treatment outcomes. METHODS: A retrospective cohort analysis was performed using routinely collected data with Malawi Ministry of Health monitoring tools from facilities providing antiretroviral therapy services in Zomba district. Patients aged 25 years and older initiated on treatment from July 2005 to June 2010 were included. Differences in survival, by age group, were determined using Kaplan-Meier survival plots and Cox proportional hazards regression models. RESULTS: There were 10,888 patients aged 25 and older. Patients aged 50 and older (N = 1419 were more likely to be male (P<0.0001 and located in rural areas (P = 0.003 than those aged 25-49. Crude survival estimates among those aged 50-59 were not statistically different from those aged 25-49 (P = 0.925. However, survival among those aged 60 and older (N = 345 was worse (P = 0.019 than among those 25-59. In the proportional hazards model, after controlling for sex and stage at initiation, survival in those aged 50-59 did not differ significantly from those aged 25-49 (hazard ratio 1.00 (95% CI: 0.79 to 1.27; P = 0.998 but the hazard ratio was 1.46 (95% CI: 1.03 to 2.06; P = 0.032 for those aged 60 and older compared to those aged 25-49. CONCLUSIONS: Treatment outcomes of those aged 50-59 are similar to those aged 25-49. A better understanding of how older adults present for and respond to treatment is critical to improving HIV services.

    Full Text Available Objetivos: La adherencia al tratamiento antirretroviral de alta eficacia (TARV se considera el gold standard para el éxito del mismo. Para mejorar la adherencia en persona privadas de libertad viviendo con VIH-Sida, se propuso la utilización del tratamiento directamente observado tomando el modelo para el tratamiento de la tuberculosis. Material y métodos: se incluyeron las mujeres VIH positivas con criterios de TARV que voluntariamente decidieron participar. Los datos principales a evaluar fueron control inicial y final de CD4 y carga viral para VIH. Resultados: estudiamos 52 mujeres, edad promedio 34 años, entre 1 y 20 años de infección VIH. CD4 menor a 100 cél/ml inicial en 16 pacientes (30.7% y final en 4 pacientes (7.6%. Carga viral indetectable inicial en ninguna paciente y final en 33 pacientes (63.4% 21 % con infecciones oportunistas, principal tuberculosis. 17% coinfectadas con HCV. El esquema de TARV más utilizado fue 2 INTR más 1 INNTR. Conclusiones: La estrategia DOT aplicada al TARV fue efectiva en nuestras pacientes, evidenciado por el aumento de los CD4 y el mayor número de pacientes con disminución de la carga viral hasta permanecer indetectables. Si bien es difícil de implementar en tratamientos crónicos consideramos que es una herramienta útil para personas privadas de libertad.Objectives: It is considered that the gold standard for success in HAART is adherence. To improve adherence amongst inmates with HIV-AIDS, the use of directly observed treatment (DOT is proposed using the tuberculosis treatment model. Material and methods: HIV positive female patients with ARVT criteria who voluntarily participated were used for the study. The initial and final CD4 cell count and HIV viral load were the principal data used for assessment purposes. Results: 52 women with an average age of 34 years were studied, with an average HIV infection time span of between 1 and 20 years. Initial CD4 cell count of <100 copies/mL in 16 patients (30.7% and an equivalent final count in 4 patients (7.6% were found. Initial undetectable viral loads were not found in any patient, while final undetectable viral loads were found in 33 (63.4%. 21% of patients had opportunistic infections. The most important of these was tuberculosis, followed by HCV co-infection. The most frequently used ARVT schedule was two NRTI with one NNTRI. Conclusions: The application of DOT strategy to ARVT was effective amongst our patients, as shown by the increase in CD4 counts and the increased number of patients with reductions in viral loads to undetectable levels. While it is a tool that is not easy to use for cases of chronic treatment, we do consider it to be useful for prison inmates.

    Objectives To identify associations between specific WHO stage 3 and 4 conditions diagnosed after ART initiation and all cause mortality for patients in resource-limited settings (RLS). Design, Setting Analysis of routine program data collected prospectively from 25 programs in eight countries between 2002 and 2010. Subjects, Participants 36,664 study participants with median ART follow-up of 1.26 years (IQR 0.55–2.27). Outcome Measures Using a proportional hazards model we identified factors associated with mortality, including the occurrence of specific WHO clinical stage 3 and 4 conditions during the 6-months following ART initiation. Results There were 2922 deaths during follow-up (8.0%). The crude mortality rate was 5.41 deaths per 100 person-years (95% CI: 5.21–5.61). The diagnosis of any WHO stage 3 or 4 condition during the first 6 months of ART was associated with increased mortality (HR: 2.21; 95% CI: 1.97–2.47). After adjustment for age, sex, region and pre-ART CD4 count, a diagnosis of extrapulmonary cryptococcosis (aHR: 3.54; 95% CI: 2.74–4.56), HIV wasting syndrome (aHR: 2.92; 95%CI: 2.21 -3.85), non-tuberculous mycobacterial infection (aHR: 2.43; 95% CI: 1.80–3.28) and Pneumocystis pneumonia (aHR: 2.17; 95% CI 1.80–3.28) were associated with the greatest increased mortality. Cerebral toxoplasmosis, pulmonary and extra-pulmonary tuberculosis, Kaposi’s sarcoma and oral and oesophageal candidiasis were associated with increased mortality, though at lower rates. Conclusions A diagnosis of certain WHO stage 3 and 4 conditions is associated with an increased risk of mortality in those initiating ART in RLS. This information will assist initiatives to reduce excess mortality, including prioritization of resources for diagnostics, therapeutic interventions and research. PMID:23935870

  2. Multi-scale modeling of HIV infection in vitro and APOBEC3G-based anti-retroviral therapy.

    Iraj Hosseini

    2012-02-01

    Full Text Available The human APOBEC3G is an innate restriction factor that, in the absence of Vif, restricts HIV-1 replication by inducing excessive deamination of cytidine residues in nascent reverse transcripts and inhibiting reverse transcription and integration. To shed light on impact of A3G-Vif interactions on HIV replication, we developed a multi-scale computational system consisting of intracellular (single-cell, cellular and extracellular (multicellular events by using ordinary differential equations. The single-cell model describes molecular-level events within individual cells (such as production and degradation of host and viral proteins, and assembly and release of new virions, whereas the multicellular model describes the viral dynamics and multiple cycles of infection within a population of cells. We estimated the model parameters either directly from previously published experimental data or by running simulations to find the optimum values. We validated our integrated model by reproducing the results of in vitro T cell culture experiments. Crucially, both downstream effects of A3G (hypermutation and reduction of viral burst size were necessary to replicate the experimental results in silico. We also used the model to study anti-HIV capability of several possible therapeutic strategies including: an antibody to Vif; upregulation of A3G; and mutated forms of A3G. According to our simulations, A3G with a mutated Vif binding site is predicted to be significantly more effective than other molecules at the same dose. Ultimately, we performed sensitivity analysis to identify important model parameters. The results showed that the timing of particle formation and virus release had the highest impacts on HIV replication. The model also predicted that the degradation of A3G by Vif is not a crucial step in HIV pathogenesis.

Elle a pour objectifs spécifiques de déterminer la proportion des grossesses chez les femmes à sérologie VIH positive, d’évaluer l’attitude du personnel de santé à l’égard des messages à donner aux femmes séropositives sous ARVs en ce qui concerne le désir de la grossesse, et relever les facteurs déterminant le désir d’avoir des enfants après la mise ne route d’un traitement par antirétroviraux . Il s’agit d’une étude descriptive transversale. Elle a été conduite auprès de 260 femmes infectées par le VIH sous ARVs et suivies dans les FOSA, ayant les services de VCT/PMTCT et des ARVs. L’étude montre que 26,9% des femmes ont été enceintes après avoir été informées de leur statut sérologique positif pour le VIH et que 38,5% des femmes séropositives sous traitement anti-rétroviral désirent avoir des enfants dans le futur. La majorité des femmes (82,7% reconnaissent l’importance de l’utilisation des contraceptifs alors que le pourcentage des femmes qui connaissent l’importance d’utiliser les ARVs pendant la grossesse et l’accouchement pour réduire le risque de transmission de la mère à l’enfant est de 76,9%. Les facteurs déterminant le désir de la grossesse parmi les femmes séropositives sont : La confiance attribuée aux anti-rétroviraux, la parité c’est-à-dire les femmes qui n’ont pas eu d’enfant ont un désir de maternité deux fois supérieur que les femmes qui ont eu au moins un enfant, et la non utilisation des méthodes contraceptives chez les femmes à sérologie VIH positives pour réduire le risque de transmission de la mère à l’enfant.

  4. Neuropathic and neurocongnitive complications of antiretroviral therapy among HIV-infected patients.

    Suvada, Jose

    2013-09-01

    The neurologic events related to antiretroviral therapy (ART) in HIV-infected ART-naive patients are relatively common. Side effects of ART and complications of HIV infection may overlap significantly. Establishing etiology of neurologic (neuropathy and neuropathic pain, changes in cognition, dementia, and myelopathy) and psychiatric (neurocognitive disorders, depression, anxiety, substance abuse and dependence, and others) complications can present a significant challenge. It has long been documented that neurologic and psychological side effects can occur with many of the agents used to treat HIV infection. Particularly, efavirenz from the non-nucleoside reverse transcriptase inhibitor (NNRTI) has been associated with neurologic and psychological complaints that may be difficult to differentiate from pre-existing mental illness, substance abuse, and HIV-related neuropsychiatric symptoms. Peripheral neuropathy (PN) of at least 6 different types is a well-known adverse effect of treatment with nucleoside reverse transcriptase inhibitors (NRTIs) in HIV-infected patients. Lack of dealing with early stages of neurologic and psychological side effects of HIV infection and Highly Active Anti-retroviral Therapy (HAART) are observed in daily practice. The purpose of this article is to identify the neurologic, neuropsychiatric and psychiatric complications related to HIV and anti-retroviral therapy, to discuss current knowledge about these disorders, and to suggest strategies for their diagnosis and management.

    Full Text Available O preço elevado de medicamentos patenteados tem intensificado o debate em torno do impacto do regime da propriedade intelectual sobre o acesso a tratamentos de saúde, merecendo destaque o caso do HIV/AIDS. A política brasileira de tratamento anti-retroviral, parte de um programa nacional que integra medidas de prevenção e promoção da saúde, permitiu o alcance de uma ampla cobertura com qualidade, tendo sido apontada como modelo para outros países. Não obstante, conforme amadurece o Programa Nacional de DST e AIDS, os gastos com a incorporação de anti-retrovirais patenteados ao esquema terapêutico para pacientes em tratamento atinge um peso, cada vez maior, em seu orçamento. O presente artigo toma em conta os desafios apresentados pelas patentes farmacêuticas à saúde pública e discute possíveis caminhos para a sustentação da política de acesso universal e gratuito ao tratamento contra HIV/AIDS no Brasil.The high prices of patented drugs have fueled the debate regarding the impact of the intellectual property system on access to treatment, with a special focus on HIV/AIDS. The Brazilian policy for antiretroviral treatment, part of a comprehensive program that includes both disease prevention and health promotion activities, has allowed the country to meet goals for coverage and quality and has been considered a model for other countries. However, as the Brazilian STD/AIDS Program reaches maturity, the increasing incorporation of patented drugs into the AIDS treatment regimen imposes an increasing burden on the country's health budget. This article discusses the public health challenges raised by pharmaceutical patents and discusses possible ways to sustain the national policy for free, universal access to HIV/AIDS treatment.

    Full Text Available OBJETIVO: Com o intuito de analisar os fatores associados à interrupção do tratamento anti-retroviral em adultos com AIDS, no Rio Grande do Norte, Brasil, realizou-se estudo nas unidades locais de referência no atendimento à AIDS. MÉTODOS: Tomou-se como critério de não interrupção o comparecimento a pelo menos 80% das visitas programadas à farmácia para o recebimento das drogas prescritas, por um período de seis meses consecutivos, após a data da prescrição. RESULTADOS: O estudo compreendeu 498 casos, dos quais 52,4% já chegaram a um serviço especializado com alguma condição indicativa de imunodeficiência. O percentual total de não interrupção foi de 64,1%. Não foi encontrada associação com as variáveis sexo, categoria de exposição e contagem de CD4+, nem com o tipo de esquema anti-retroviral. Os resultados da análise multivariada revelaram associações significativas entre interrupção e início do tratamento após internamento hospitalar, uso de drogas, tratamento psiquiátrico, baixo grau de escolaridade e idade de 25 a 34 anos. CONCLUSÃO: Os resultados sugerem que a interrupção do tratamento é um problema crítico nos seis primeiros meses seguintes ao início da terapia anti-retroviral em indivíduos virgens de tratamento, e, especialmente, entre os adultos jovens, com história prévia de tratamento psiquiátrico, que usam ou fizeram uso de drogas lícitas ou ilícitas até um ano antes de iniciar o tratamento com anti-retrovirais, que iniciam a terapia após internamento hospitalar e têm baixo nível de escolaridade.BACKGROUND: The purpose of this study is to determine factors associated to the interruption of antiretroviral treatment in adults with AIDS in the State of Rio Grande do Norte, Brazil.

    Full Text Available Since the emergence of acquired immune deficiency syndrome (AIDS about three decades ago, several renal disorders have been reported as common complications of human immunodeficiency virus (HIV infection. These renal disorders result from diverse etiologies. The aim of this cross-sectional study was to determine the prevalence and clinical and laboratory characteristics of anti-retroviral-naοve HIV-infected patients with impaired kidney disorder in South-South Nigeria. This study was conducted on patients presenting at the University of Benin Teaching Hospital, Benin City in South-South Nigeria for six months. The patients′ demographic data and clinical, hematological and biochemical parameters were assessed. Their glomerular filtration rate (GFR was calculated and the protein excretion was assessed from the protein- creatinine ratio. Data were analyzed using statistical software program SPSS version 15.0. Threehundred and eighty-three patients with a mean age of 35.39 ± 8.78 years and a male: female ratio of 1:1 were studied; 53.3% had evidence of kidney disorder. The main clinical features in patients with kidney disorder were evidence of fluid retention, urinary symptoms, pallor and encephalopathy. The mean systolic and diastolic blood pressures were 115.33 ± 17.17 and 72.33 ± 14.31 mm Hg, respectively. The mean estimated GFR was 52.5 mL/min/1.73 m 2 . Patients with kidney disorder had higher proteinuria (P = 0.001, lower mean CD4 cell count and packed cell volume (P = 0.019 and 0.001, respectively. Kidney disorder is a common complication in HIV-infected patients, and they have clinical and laboratory anomalies. Screening of HIV/AIDS patients at the time of diagnosis will facilitate early diagnosis of kidney disorders in them.

    2003-04-01

    Full Text Available A aderência ao tratamento é um dos principais problemas relacionados à terapia anti-retroviral, já que a tomada incompleta dos medicamentos pode levar à resistência viral. Efeitos colaterais podem interferir com a qualidade de vida dos pacientes. Buscou-se estimar níveis de aderência à terapia e investigar seus determinantes, através de um estudo transversal. Definiram-se dois pontos de corte como boa aderência: a tomada de pelo menos 80% ou de 95% da medicação conforme a prescrição. Realizaram-se entrevistas semi-estruturadas em uma amostra seqüencial de 150 pacientes atendidos no Hospital-Dia de Brasília. Observou-se que a média de aderência foi 85,8%. As variáveis que se mostraram significativamente associadas à baixa aderência foram: idade, escolaridade, situação de emprego, rendas pessoal e familiar, uso de substâncias ilícitas, estrutura familiar e/ou comunitária, presença de infecção oportunista no momento do diagnóstico e ocorrência de efeitos colaterais relacionados à terapia. As razões de prevalência variaram de 1,6 a 4,5. Concluiu-se que variáveis sócio-econômicas e de hábitos tiveram maior força de associação com o nível de aderência do que as relacionadas com a doença ou com o tratamento.

    Nef is an HIV-1 accessory protein essential for AIDS progression and an attractive target for drug discovery. Lack of a catalytic function makes Nef difficult to assay in chemical library screens. We developed a high-throughput screening assay for inhibitors of Nef function by coupling it to one of its host cell binding partners, the Src-family kinase Hck. Hck activation is dependent upon Nef in this assay, providing a direct readout of Nef activity in vitro. Using this screen, a unique diphe...

    Purpose : To evaluate proton magnetic resonance spectroscopy ({sup 1}H MRS) features in order to assess hepatocellular activation in chronic hepatitis C and human immunodeficiency virus/hepatitis C (HIV/HCV) co-infected patients. Material and Methods : Liver in vivo {sup 1}H MR spectra were obtained in 14 patients with hepatitis C virus infection (HCV), 20 HIV/HCV co-infected individuals, and 24 healthy volunteers. Resonances of lipids, glutamine/glutamate (Glx), phosphomonoesters (PME), glycogen/glucose (Glc) were assessed and metabolite ratios to total lipids (TL) were calculated. Results : A significant increase in Glx/TL and PME/TL was observed in the HCV group as compared to healthy individuals. Patients with HIV and HCV co-infection had a further increase of all metabolite ratios. Changes in metabolite ratios were due to both the increase in particular metabolite contents and to the decrease in lipid levels. HIV/HCV-infected patients treated with highly active anti-retroviral therapy (HAART) showed elevated PME and Glx levels and significantly decreased TL compared to patients not undergoing anti-retroviral treatment. Conclusions : Our findings suggest clinical usefulness of liver {sup 1}H MR spectroscopy in detecting even slight disturbances in liver metabolism.

    Full Text Available Opportunistic and intestinal parasite infections are common health problem among HIV/AIDS patients. Early detection and treatment of these parasites are important to improve the quality of life of this category of patients. The occurrence of intestinal parasites among 400 patients on highly active anti-retroviral drug therapy (HAART aged 11-60 years was investigated. Standard parasitological techniques like direct microscopy, formol ether concentration and modified Ziehl- Neelsen staining techniques were used to analyze the stool samples. Intestinal parasite infections were positive in 116 (29% of the subjects on HAART while control subjects had 12 (12% and the difference was statistically significant (P<0.05. Subjects in the age group 21-30 years had the highest infection rate 54 (35.1%. There was no statistically significant difference in infection according to age (P>0.05. Females 76 (32.5% had a higher prevalence rate than males 40 (24.1%. But there was no statistically significant difference in infection according to gender (P<0.05. Patients with CD4 count of less than 200 cells/mm3 were observed to be more infected than those with CD4 count of more than 200 cells/mm3. There was a strong positive correlation (r=0.94 between CD4 count and the occurrence of intestinal parasite infection. Protozoan parasites 84 (21.0% accounted for a higher prevalence rate than helminthic parasites 32 (8.0%. These findings has revealed a high prevalence of intestinal parasite infection among patients on HAART thus the routine screening of stool samples from these category of patients for intestinal parasites is advocated for effective management of the disease.

    Ayalu A Reda

    Full Text Available BACKGROUND: Antiretroviral treatment (ART has been introduced in Ethiopia a decade ago and continues to be scaled up. However, there is dearth of literature on the impact of ART on changes in CD4 lymphocyte count and weight among patients on treatment. OBJECTIVE: To determine the predictors of change in CD4 lymphocyte count and weight among HIV/AIDS infected patients taking antiretroviral treatment in eastern Ethiopia. METHODS: A retrospective cohort study was conducted among HIV/AIDS patients taking ART from 2005 to 2010. A sample of 1540 HIV infected adult patients who started antiretroviral therapy in hospitals located in eastern Ethiopia were included in the study. The primary outcomes of interest were changes in CD4 count and weight. Descriptive statistics and multivariable regression analyses were performed to examine the outcomes among the cohort. RESULTS: Both the median CD4 lymphocyte counts and weight showed improvements in the follow up periods. The multivariate analysis shows that the duration of ART was an important predictor of improvements in CD4 lymphocyte count (beta 7.91; 95% CI 7.48-8.34; p 0.000 and weight (beta 0.15; 95% CI 0.13-0.18; p 0.000. Advanced WHO clinical stage, lower baseline CD4 cell count, and baseline hemoglobin levels were factors associated with decline in weight. Actively working patients had higher CD4 lymphocyte count and weight compared to those that were ambulatory (p<0.05. CONCLUSION: We detected a substantial increment in weight and CD4 lymphocyte count among the patients who were taking ART in eastern Ethiopia. Patients who are of older age, with low initial CD4 lymphocyte count, late stage of the WHO clinical stages and lower hemoglobin level may need special attention. The reasons for the improved findings on CD4 count and weight throughout the five years of follow up merit further investigation.

    Background Foci of the HIV epidemic and helminthic infections largely overlap geographically. Treatment options for helminth infections are limited, and there is a paucity of drug-development research in this area. Limited evidence suggests that antiretroviral therapy (ART) reduces prevalence of helminth infections in HIV-infected individuals. We investigated whether ART exposure and cotrimoxazole preventive therapy (CTX-P) is associated with a reduced prevalence of helminth infections. Metho...

  9. Nutritional therapy for active Crohn's disease

    2008-01-01

    Nutritional therapy for active Crohn's disease (CD) is an underutilised form of treatment in adult patients, though its use is common in the paediatric population. There is evidence that nutritional therapy can effectively induce remission of CD in adult patients. Enteral nutrition therapy is safe and generally well tolerated, leta-analysis data suggest that corticosteroids are superior to nutritional treatment for induction of remission in active CD. However, the potential side effects of such pharmacotherapy must be taken into consideration. This review examines the evidence for the efficacy of elemental and polymeric diets, and the use of total parenteral nutrition in active CD.

    Full Text Available This paper addresses the concept and use of the instrument named ‘activities’ in occupational therapy, sustained by the propositions of the Dynamic Occupational Therapy Method (DOTM. Initially, we present general aspects related to the activities in the DOTM such as the option for the name ‘activities’, its conceptual definition, use as a tool, and active participation in the dynamic of triadic relationship. Further, it approaches the character of activities: therapeutic, educational and social qualities, which distinguish this peculiar occupational therapy. Moreover, the paper highlights the use of activities as a tool, both as a central element of the processes that should underpin clinical reasoning (observation, information, association, setting up space of historicity, and construction of narrative, and as an element belonging to diagnostic procedures, to the course of clinical process, and to evaluation. Finally, we present our understanding of what we call resources in DOTM, and its intrinsic connection with the possibility of performing ‘activities’. For the creation of DOTM, occupational therapy, as a practice focused on the uniqueness of the case, was made the object of study in order to promote knowledge construction. The conceptual and instrumental framework presented in this work held this effort. We hope that this study could be useful for initial and continuing training in Occupational Therapy as well as for enriching the debate on the use of ‘activities’ in our profession.

    Full Text Available Dislipidemias podem ser observadas precocemente entre pacientes com AIDS. Frequentemente, estas anormalidades lipídicas incluem HDL baixo e moderado aumento dos triglicérides sanguíneos. A terapia anti-retroviral combinada (HAART pode agravar a dislipidemia nestes pacientes, com importante aumento nos triglicérides e no LDL. Vários mecanismos são propostos para explicar a dislipidemia mista observada nestes indivíduos, incluindo diferentes etapas do metabolismo lipídico. A importância do tratamento desses distúrbios lipídicos tem se tornado evidente com o aumento da expectativa de vida e os relatos de complicações cardiovasculares nestes pacientes. Existe um estado de resistência à insulina nos pacientes com AIDS em tratamento com HAART,que apresentam lipodistrofia, hipertrigliceridemia e baixos níveis de HDL. Drogas retro-antivirais são metabolizadas pelo CYP P450 3A4 e interações com algumas estatinas, especialmente com sinvastatina podem ocorrer. O tratamento com agentes hipolipemiantes deve ser baseado no perfil lipídico e no risco de coronariopatia. Para hipertrigliceridemias, fibratos (principalmente fenofibrato ou bezafibrato devem ser as drogas de escolha, bem como as estatinas (principalmente pravastatina. Terapia combinada usando estatinas mais fibratos é recomendada para dislipidemias mistas graves e sempre sob rigoroso monitoramento de efeitos adversos.Lipid alterations can be observed early among patients with AIDS disease. Commonly, these lipid abnormalities include low HDL-C and modest increase in triglyceride plasma levels. Highly Active Anti-Retroviral Therapy (HAART in these patients may aggravate the dyslipidemia, with notable increases in triglycerides as well as in LDL-C. There are several mechanisms proposed to explain the mixed hyperlipidemia observed in these subjects, including different steps in lipid metabolism. The importance of the treatment of dyslipidemia became evident with the increased life

  16. Mycobacterial antigen driven activation of CD14++CD16- monocytes is a predictor of tuberculosis-associated immune reconstitution inflammatory syndrome.

    2014-10-01

    Full Text Available Paradoxical tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS is an aberrant inflammatory response occurring in a subset of TB-HIV co-infected patients initiating anti-retroviral therapy (ART. Here, we examined monocyte activation by prospectively quantitating pro-inflammatory plasma markers and monocyte subsets in TB-HIV co-infected patients from a South Indian cohort at baseline and following ART initiation at the time of IRIS, or at equivalent time points in non-IRIS controls. Pro-inflammatory biomarkers of innate and myeloid cell activation were increased in plasma of IRIS patients pre-ART and at the time of IRIS; this association was confirmed in a second cohort in South Africa. Increased expression of these markers correlated with elevated antigen load as measured by higher sputum culture grade and shorter duration of anti-TB therapy. Phenotypic analysis revealed the frequency of CD14(++CD16(- monocytes was an independent predictor of TB-IRIS, and was closely associated with plasma levels of CRP, TNF, IL-6 and tissue factor during IRIS. In addition, production of inflammatory cytokines by monocytes was higher in IRIS patients compared to controls pre-ART. These data point to a major role of mycobacterial antigen load and myeloid cell hyperactivation in the pathogenesis of TB-IRIS, and implicate monocytes and monocyte-derived cytokines as potential targets for TB-IRIS prevention or treatment.

    Fairchild, R.G. (ed.)

    1985-04-18

    This Workshop was held concurrently with an IAEA Research Coordination Meeting on Exploration of the Possibility of High-LET Radiation for Non-conventional Radiotherapy in Cancer. The Workshop on Photon Activation Therapy (PAT) was given as a special session on April 18, as it was thoght PAT might eventually be found to be attractive to developing countries, which is a major concern of the IAEA. An effort was made to bring together representatives of the various groups known to be actively working on PAT; these included investigators from Sweden and Japan as well as the US. It is hoped that this compendium of papers will be of use to those currently active in this developing field, as well as to those who might join this area of endeavor in the future.

    Full Text Available Background. Dietary supplementation has been used as a mechanism to augment the immune system. Adjunctive therapy with L-arginine has the potential to improve outcomes in active tuberculosis. Methods. In a randomized clinical trial 63 participants with smear-positive pulmonary tuberculosis in Markazi Province of Iran were given arginine or placebo for 4 weeks in addition to conventional chemotherapy. The final treatment success, sputum conversion, weight gain, and clinical symptoms after one and two months were considered as primary outcomes and secondary outcomes were ESR, CRP, and Hg. Data were collected and analyzed with SPSS software (ver. 18. Results. Arginine supplementation reduced constitutional symptoms (P=0.032 in patients with smear-positive TB at the end of the first month of treatment. Arginine treated patients had significantly increased BMI at the end of the first and second months of treatment (P=0.032 and P=0.04 and a reduced CRP at the end of the first month of treatment (P=0.03 versus placebo group. Conclusion. Arginine is useful as an adjunctive therapy in patients with active tuberculosis, in which the effects are more likely mediated by the increased production of nitric oxide and improved constitutional symptoms and weight gain. This trial is registered with Clinical Trials Registry of Iran: IRCT201211179855N2.

    Full Text Available Abstract German-Austrian recommendations for HIV1-therapy in pregnancy - Update 2008 Bernd Buchholz (University Medical Centre Mannheim, Pediatric Clinic, Matthias Beichert (Mannheim, Gynecology and Obstetrics Practice, Ulrich Marcus (Robert Koch Institute, Berlin, Thomas Grubert, Andrea Gingelmaier (Gynecology Clinic of the Ludwig Maximilians University of Munich, Dr. med. Annette Haberl (HIV-Department, J. W. Goethe-University Hospital, Frankfurt, Dr. med. Brigitte Schmied (Otto-Wagner Spital, Wien. In Germany during the last years about 200-250 HIV1-infected pregnant women delivered a baby each year, a number that is currently increasing. To determine the HIV-status early in pregnancy voluntary HIV-testing of all pregnant women is recommended in Germany and Austria as part of prenatal care. In those cases, where HIV1-infection was known during pregnancy, since 1995 the rate of vertical transmission of HIV1 was reduced to 1-2%. This low transmission rate has been achieved by the combination of anti-retroviral therapy of pregnant women, caesarean section scheduled before onset of labour, anti-retroviral post exposition prophylaxis in the newborn and refraining from breast-feeding by the HIV1-infected mother. To keep pace with new results in research, approval of new anti-retroviral drugs and changes in the general treatment recommendations for HIV1-infected adults, in 1998, 2001, 2003 and 2005 an interdisciplinary consensus meeting was held. Gynaecologists, infectious disease specialists, paediatricians, pharmacologists, virologists and members of the German AIDS Hilfe (NGO were participating in this conference to update the prevention strategies. A fifth update became necessary in 2008. The updating process was started in January 2008 and was terminated in September 2008. The guidelines provide new recommendations on the indication and the starting point for HIV-therapy in pregnancies without complications, drugs and drug combinations to be

    2012-01-01

    Introduction Our objective was to compare the bone and renal effects among HIV-infected patients randomized to abacavir or tenofovir-based combination anti-retroviral therapy. Methods In an open-label randomized trial, HIV-infected patients were randomized to switch from zidovudine/lamivudine (AZT....../3TC) to abacavir/lamivudine (ABC/3TC) or tenofovir/emtricitabine (TDF/FTC). We measured bone mass density (BMD) and bone turnover biomarkers (osteocalcin, osteocalcin, procollagen type 1 N-terminal propeptide (P1NP), alkaline phosphatase, type I collagen cross-linked C-telopeptide (CTx), and...

  2. Synergistic Reactivation of Latent HIV Expression by Ingenol-3-Angelate, PEP005, Targeted NF-kB Signaling in Combination with JQ1 Induced p-TEFb Activation.

    Although anti-retroviral therapy (ART) is highly effective in suppressing HIV replication, it fails to eradicate the virus from HIV-infected individuals. Stable latent HIV reservoirs are rapidly established early after HIV infection. Therefore, effective strategies for eradication of the HIV reservoirs are urgently needed. We report that ingenol-3-angelate (PEP005), the only active component in a previously FDA approved drug (PICATO) for the topical treatment of precancerous actinic keratosis, can effectively reactivate latent HIV in vitro and ex vivo with relatively low cellular toxicity. Biochemical analysis showed that PEP005 reactivated latent HIV through the induction of the pS643/S676-PKCδ/θ-IκBα/ε-NF-κB signaling pathway. Importantly, PEP005 alone was sufficient to induce expression of fully elongated and processed HIV RNAs in primary CD4+ T cells from HIV infected individuals receiving suppressive ART. Furthermore, PEP005 and the P-TEFb agonist, JQ1, exhibited synergism in reactivation of latent HIV with a combined effect that is 7.5-fold higher than the effect of PEP005 alone. Conversely, PEP005 suppressed HIV infection of primary CD4+ T cells through down-modulation of cell surface expression of HIV co-receptors. This anti-cancer compound is a potential candidate for advancing HIV eradication strategies. PMID:26225771

  3. Central and peripheral markers of neurodegeneration and monocyte activation in HIV-associated neurocognitive disorders.

    McGuire, Jennifer L; Gill, Alexander J; Douglas, Steven D; Kolson, Dennis L

    2015-08-01

    HIV-associated neurocognitive disorders (HAND) affect up to 50 % of HIV-infected adults, independently predict HIV morbidity/mortality, and are associated with neuronal damage and monocyte activation. Cerebrospinal fluid (CSF) neurofilament subunits (NFL, pNFH) are sensitive surrogate markers of neuronal damage in several neurodegenerative diseases. In HIV, CSF NFL is elevated in individuals with and without cognitive impairment, suggesting early/persistent neuronal injury during HIV infection. Although individuals with severe cognitive impairment (HIV-associated dementia (HAD)) express higher CSF NFL levels than cognitively normal HIV-infected individuals, the relationships between severity of cognitive impairment, monocyte activation, neurofilament expression, and systemic infection are unclear. We performed a retrospective cross-sectional study of 48 HIV-infected adults with varying levels of cognitive impairment, not receiving antiretroviral therapy (ART), enrolled in the CNS Anti-Retroviral Therapy Effects Research (CHARTER) study. We quantified NFL, pNFH, and monocyte activation markers (sCD14/sCD163) in paired CSF/plasma samples. By examining subjects off ART, these correlations are not confounded by possible effects of ART on inflammation and neurodegeneration. We found that CSF NFL levels were elevated in individuals with HAD compared to cognitively normal or mildly impaired individuals with CD4+ T-lymphocyte nadirs ≤200. In addition, CSF NFL levels were significantly positively correlated to plasma HIV-1 RNA viral load and negatively correlated to plasma CD4+ T-lymphocyte count, suggesting a link between neuronal injury and systemic HIV infection. Finally, CSF NFL was significantly positively correlated with CSF pNFH, sCD163, and sCD14, demonstrating that monocyte activation within the CNS compartment is directly associated with neuronal injury at all stages of HAND.

  4. HIV-1 latency in actively dividing human T cell lines

    2008-04-01

    Full Text Available Abstract Background Eradication of HIV-1 from an infected individual cannot be achieved by current drug regimens. Viral reservoirs established early during the infection remain unaffected by anti-retroviral therapy and are able to replenish systemic infection upon interruption of the treatment. Therapeutic targeting of viral latency will require a better understanding of the basic mechanisms underlying the establishment and long-term maintenance of HIV-1 in resting memory CD4 T cells, the most prominent reservoir of transcriptional silent provirus. However, the molecular mechanisms that permit long-term transcriptional control of proviral gene expression in these cells are still not well understood. Exploring the molecular details of viral latency will provide new insights for eventual future therapeutics that aim at viral eradication. Results We set out to develop a new in vitro HIV-1 latency model system using the doxycycline (dox-inducible HIV-rtTA variant. Stable cell clones were generated with a silent HIV-1 provirus, which can subsequently be activated by dox-addition. Surprisingly, only a minority of the cells was able to induce viral gene expression and a spreading infection, eventhough these experiments were performed with the actively dividing SupT1 T cell line. These latent proviruses are responsive to TNFα treatment and alteration of the DNA methylation status with 5-Azacytidine or genistein, but not responsive to the regular T cell activators PMA and IL2. Follow-up experiments in several T cell lines and with wild-type HIV-1 support these findings. Conclusion We describe the development of a new in vitro model for HIV-1 latency and discuss the advantages of this system. The data suggest that HIV-1 proviral latency is not restricted to resting T cells, but rather an intrinsic property of the virus.

  5. Clinical application of photon activation therapy

    Despite small improvements in median survival, high-grade astrocytoma remains a lethal disease with only anecdotal long-term survivors. The Brain Tumor Study Group Protocols have confirmed the value of radiation therapy and have further demonstrated that a dose-response relationship exists with doses of 5000, 5500, and 6000 cGy. However, 6000 cGy remains the upper limit of dose tolerated if external radiation therapy is used. Therefore the authors propose to combine the advantages of brachytherapy and sensitizers with halogenated pyrimidines (IUDR). By using stereotactically placed radiation sources with energies slightly above the K absorption edge of iodine they expect to obtain a significant further increase in therapeutic effect. This is due to enhancement of the physical dose, which is, furthermore, of higher biological effectiveness. Responsible for this effect are Auger electrons created in the process, which deposit their energy within the diameter of the nucleus. The dose delivered by Auger electrons is in many respects comparable with high-LET radiation. Since selective uptake of IUDR in brain tumor cells is assumed, the dose enhancement would localize itself into the tumor. Normal brain tolerance should be little, if at all, affected since normal brain would receive only low-LET radiation from the implanted samarium sources

    2016-07-01

    Macrophage activation syndrome (MAS) is a severe and potential life-threatening complication of childhood systemic inflammatory disorders. Corticosteroids are commonly used as the first-line therapy for MAS. We report four patients with MAS who were successfully treated with dexamethasone palmitate (DexP), a liposome-incorporated dexamethasone, much more efficient than free corticosteroids. DexP effectively inhibited inflammation in MAS patients in whom the response to pulse methylprednisolone was not sufficient to manage their diseases. DexP was also effective as the first-line therapy for MAS. Based on these findings, DexP is an effective therapy in treating MAS patients. PMID:24754272

    Wainberg, Mark A.; Dascal, Andre; Mendelson, Jack

    1991-01-01

    The replication cycle of human immunodeficiency virus type 1 (HIV-1) and other retroviruses consists of four stages: attachment of the virus to specific receptors on the cell surface; uncoating of the viral nucleic acid and conversion to DNA; production of viral RNA and proteins; and assembly and liberation of progeny virus from the cell. Each of these steps represents a potential target for antiviral chemotherapy. Combinations of drugs which act against different steps in the viral replicati...

  8. HIV quasispecies dynamics during pro-active treatment switching: impact on multi-drug resistance and resistance archiving in latent reservoirs.

    Max von Kleist

    Full Text Available The human immunodeficiency virus (HIV can be suppressed by highly active anti-retroviral therapy (HAART in the majority of infected patients. Nevertheless, treatment interruptions inevitably result in viral rebounds from persistent, latently infected cells, necessitating lifelong treatment. Virological failure due to resistance development is a frequent event and the major threat to treatment success. Currently, it is recommended to change treatment after the confirmation of virological failure. However, at the moment virological failure is detected, drug resistant mutants already replicate in great numbers. They infect numerous cells, many of which will turn into latently infected cells. This pool of cells represents an archive of resistance, which has the potential of limiting future treatment options. The objective of this study was to design a treatment strategy for treatment-naive patients that decreases the likelihood of early treatment failure and preserves future treatment options. We propose to apply a single, pro-active treatment switch, following a period of treatment with an induction regimen. The main goal of the induction regimen is to decrease the abundance of randomly generated mutants that confer resistance to the maintenance regimen, thereby increasing subsequent treatment success. Treatment is switched before the overgrowth and archiving of mutant strains that carry resistance against the induction regimen and would limit its future re-use. In silico modelling shows that an optimal trade-off is achieved by switching treatment at days after the initiation of antiviral therapy. Evaluation of the proposed treatment strategy demonstrated significant improvements in terms of resistance archiving and virological response, as compared to conventional HAART. While continuous pro-active treatment alternation improved the clinical outcome in a randomized trial, our results indicate that a similar improvement might also be reached after

  9. Persistence of endometrial activity after radiation therapy for cervical carcinoma

    Radiation therapy is a proved treatment for cervical carcinoma; however, it destroys ovarian function and has been thought to ablate the endometrium. Estrogen replacement therapy is often prescribed for patients with cervical carcinoma after radiation therapy. A review of records of six teaching hospitals revealed 16 patients who had endometrial sampling for uterine bleeding after standard radiation therapy for cervical carcinoma. Fifteen patients underwent dilatation and curettage, and one patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy when a dilatation and curettage was unsuccessful. Six patients had fibrosis and inflammation of the endometrial cavity, seven had proliferative endometrium, one had cystic hyperplasia, one had atypical adenomatous hyperplasia, and one had adenocarcinoma. Although the number of patients who have an active endometrium after radiation therapy for cervical carcinoma is not known, this report demonstrates that proliferative endometrium may persist, and these patients may develop endometrial hyperplasia or adenocarcinoma. Studies have indicated that patients with normal endometrial glands have an increased risk of developing endometrial adenocarcinoma if they are treated with unopposed estrogen. Patients who have had radiation therapy for cervical carcinoma should be treated with estrogen and a progestational agent to avoid endometrial stimulation from unopposed estrogen therapy

  10. An oral high dose of cholecalciferol restores vitamin D status in deficient postmenopausal HIV-1-infected women independently of protease inhibitors therapy: a pilot study.

    The best repletion and maintenance dosing regimens with cholecalciferol in vitamin D-deficient HIV-1 patients remain unknown. Protease inhibitors (PIs) have been shown to inhibit vitamin D 1α- and 25α-hydroxylation in hepatocyte and monocyte cultures. We therefore evaluated the effect of a single high dose of cholecalciferol in vitamin D-deficient HIV-1 postmenopausal women undergoing treatment with highly active anti-retroviral therapy (cART), with and without PIs. Forty HIV-1 postmenopausal women treated with cART, with hypovitaminosis D (ng/ml), were enrolled. We measured serum changes of 25-hydroxyvitamin D [25(OH)D]; 1,25-dihydroxyvitamin D [1,25(OH)2D], parathyroid hormone (PTH), serum calcium, and urinary calcium excretion following a loading dose of 600,000 IU of cholecalciferol after 3, 30, 60, 90, and 120 days. Patients were divided into two groups, whether or not they were taking PI. A significant increase in mean 25(OH)D and 1,25(OH)2D levels at day 3 and throughout the entire observation period was found in both groups (p < 0.001). PTH levels concomitantly decreased in both groups (p < 0.001). Mean albumin-adjusted serum calcium increases with respect to baseline were significant only at day 3 and day 30 for both groups (p < 0.01). Considering remaining parameters, there were no significant differences between the groups at any time, by two-way RM ANOVA. An oral dose of 600,000 IU of cholecalciferol in HIV-1 postmenopausal women rapidly increases 25(OH)D and 1,25(OH)2D levels reducing PTH levels, regardless of the presence of PIs in the cART scheme.

    2016-01-01

    Full Text Available Retrospective research of 381 clinical records is conducted to study HIV infection influence on stationary stage of tuberculosis treatment outcome in HIV-TB co-infected patients. All cases were divided depending on a hospitalization outcome on favorable and adverse. At most of patients tuberculosis of respiratory organs met. Immunological researches were conducted, the stage of HIV infection was registered and the issue of purpose of anti-retroviral therapy was resolved. Besides, as indirect signs of an immunodeficiency at the patients with a combination of tuberculosis and HIV infection who were on hospitalization the indicators received when carrying out clinical laboratory trials were analyzed: absolute and relative quantity of lymphocytes according to the general blood test, the contents the globulin fractions and circulating immune complexes concentration according to the clinical chemistry blood test. At an assessment of results in both groups of research more than at a half of patients existence of HIV infection at late stages that speaks about late identification and neglect of an immunodeficiency was revealed. At patients with tuberculosis of lungs in combination with HIV infection at a failure statistically significant decrease in an immunoregulatory index is revealed. It is interesting that the level of CD4 lymphocytes and a stage of HIV infection had no impact on the co-infection’s outcome. However, existence of virus loa ding more than 100 000 copies/ml reduced probability favorable an outcome of treatment of tuberculosis at the patient with HIV infection. Timely purpose of anti-retroviral therapy at patients with co-infection increased chances of treatment of tuberculosis at patients with an immunodeficiency. Frequency of adverse side effect of antiviral therapy met equally often at patients in both groups. Thus, patients at any stages of HIV infection with any forms of tuberculosis, including generalized, had a

  12. Carbon Beam Radio-Therapy and Research Activities at HIMAC

    Radio-therapy with carbon ion beam has been carried out since 1994 at HIMAC (Heavy Ion Medical Accelerator in Chiba) in NIRS (National Institute of Radiological Sciences). Now, many types of tumors can be treated with carbon beam with excellent local controls of the tumors. Stimulated with good clinical results, requirement of the dedicated compact facility for carbon beam radio-therapy is increased. To realize this requirement, design study of the facility and the R and D's of the key components in this design are promoted by NIRS. According successful results of these activities, the dedicated compact facility will be realized in Gunma University. In this facility, the established irradiation method is expected to use, which is passive irradiation method with wobbler magnets and ridge filter. In this presentation, above R and D's will be presented together with clinical results and basic research activities at HIMAC

  13. Low level laser therapy reduces inflammation in activated Achilles tendinitis

    Bjordal, Jan M.; Iversen, Vegard; Lopes-Martins, Rodrigo Alvaro B.

    2006-02-01

    Objective: Low level laser therapy (LLLT) has been forwarded as therapy for osteoarthritis and tendinopathy. Results in animal and cell studies suggest that LLLT may act through a biological mechanism of inflammatory modulation. The current study was designed to investigate if LLLT has an anti-inflammatory effect on activated tendinitis of the Achilles tendon. Methods: Seven patients with bilateral Achilles tendonitis (14 tendons) who had aggravated symptoms by pain-inducing activity immediately prior to the study. LLLT (1.8 Joules for each of three points along the Achilles tendon with 904nm infrared laser) and placebo LLLT were administered to either Achilles tendons in a random order to which patients and therapist were blinded. Inflammation was examined by 1) mini-invasive microdialysis for measuring the concentration of inflammatory marker PGE II in the peritendinous tissue, 2) ultrasound with Doppler measurement of peri- and intratendinous blood flow, 3) pressure pain algometry and 4) single hop test. Results: PGE 2- levels were significantly reduced at 75, 90 and 105 minutes after active LLLT compared both to pre-treatment levels (p=0.026) and to placebo LLLT (p=0.009). Changes in pressure pain threshold (PPT) were significantly different (P=0.012) between groups. PPT increased by a mean value of 0.19 kg/cm2 [95%CI:0.04 to 0.34] after treatment in the active LLLT group, while pressure pain threshold was reduced by -0.20 kg/cm2 [95%CI:-0.45 to 0.05] after placebo LLLT. Conclusion: LLLT can be used to reduce inflammatory musculskeletal pain as it reduces inflammation and increases pressure pain threshold levels in activity-induced pain episodes of Achilles tendinopathy.

    The paper presents the results obtained in the assurance of the whole traceability chain in the measurement of the activity for a particular group of radionuclides used as therapeutic pharmaceuticals: strong beta - weak gamma emitters, such as: 153 Sm, 177 Lu, 186 Re, 188 Re. The regulations regarding the uncertainty of the activity of therapy radiopharmaceuticals impose a maximum limit of 5%. All the above mentioned radionuclides belong to the group of triangular decay scheme and consequently they were standardized absolutely by the 4{pi}{beta}-{gamma} coincidence method. The solutions were then used for the calibration of the secondary standard, consisting from a 'Centronic I.G.12/20 A' ionization chamber. The calibration was transferred to the commercial radioisotope calibrators, as initial calibration figures. Some of these results are presented in the paper. (author)

  15. [Practice of Behavioral Activation in Cognitive-behavioral Therapy].

    Kitagawa, Nobuki

    2015-01-01

    An approach focusing on behavioral activation (BA) was adopted in the cognitive therapy of A. T. Beck, and it came to be considered that BA can play an important role in cognitive-behavioral therapy (CBT) for depression. Therefore, in recent years, BA based on clinical behavior analysis has been developed as a new treatment (Martell, et al.). The core characteristics are as follows: 1) focusing attention on context in daily life to promote the behavior control of patients and avoidance of a hatred experience ; 2) breaking the vicious circle; 3) promoting the behavior according to the purpose that the patients originally expect; 4) recognizing a relationship between behavior and the situation (contingency), thereby recovering self-efficacy tied to the long-term results that one originally expects. This does not increase pleasant activity at random when the patient is inactive, or give a sense of accomplishment. We know that depression is maintained by conducting functional analysis of detailed life behavior, and encourage the patients to have healthy behavior according to individual values. We help them to complete schedules regardless of mood and reflect on the results patiently. It is considered that those processes are important. BA may be easy to apply in clinical practice and effective for the chronic cases, or the patients in a convalescent stage. Also, in principle in the CBT for major depression, it may be effective that behavioral activation is provided in an early stage, and cognitive reconstruction in a latter stage. However, an approach to carry out functional analysis by small steps with careful activity monitoring is essential when the symptoms are severe. Furthermore, it should be considered that the way of psychoeducation requires caution because we encourage rest in the treatment of depression in our country. In particular, we must be careful not to take an attitude that an inactive behavior pattern is unproductive only based model cases. PMID

    2016-01-01

    This work investigates X-PACT (X-ray Psoralen Activated Cancer Therapy): a new approach for the treatment of solid cancer. X-PACT utilizes psoralen, a potent anti-cancer therapeutic with current application to proliferative disease and extracorporeal photopheresis (ECP) of cutaneous T Cell Lymphoma. An immunogenic role for light-activated psoralen has been reported, contributing to long-term clinical responses. Psoralen therapies have to-date been limited to superficial or extracorporeal scenarios due to the requirement for psoralen activation by UVA light, which has limited penetration in tissue. X-PACT solves this challenge by activating psoralen with UV light emitted from novel non-tethered phosphors (co-incubated with psoralen) that absorb x-rays and re-radiate (phosphoresce) at UV wavelengths. The efficacy of X-PACT was evaluated in both in-vitro and in-vivo settings. In-vitro studies utilized breast (4T1), glioma (CT2A) and sarcoma (KP-B) cell lines. Cells were exposed to X-PACT treatments where the concentrations of drug (psoralen and phosphor) and radiation parameters (energy, dose, and dose rate) were varied. Efficacy was evaluated primarily using flow cell cytometry in combination with complimentary assays, and the in-vivo mouse study. In an in-vitro study, we show that X-PACT induces significant tumor cell apoptosis and cytotoxicity, unlike psoralen or phosphor alone (p4T1 tumors, we show that the rate of tumor growth is slower with X-PACT than with saline or AMT + X-ray (p<0.0001). Overall these studies demonstrate a potential therapeutic effect for X-PACT, and provide a foundation and rationale for future studies. In summary, X-PACT represents a novel treatment approach in which well-tolerated low doses of x-ray radiation are delivered to a specific tumor site to generate UVA light which in-turn unleashes both short- and potentially long-term antitumor activity of photo-active therapeutics like psoralen.

  18. Active immunization therapies for Parkinson's disease and multiple system atrophy.

    Schneeberger, Achim; Tierney, Lanay; Mandler, Markus

    2016-02-01

    Vaccination is increasingly being investigated as a potential treatment for synucleinopathies, a group of neurodegenerative diseases including Parkinson's disease, multiple system atrophy, and dementia with Lewy bodies associated with α-synuclein pathology. All lack a causal therapy. Development of novel, disease-altering treatment strategies is urgently needed. Vaccination has positioned itself as a prime strategy for addressing these diseases because it is broadly applicable, requires infrequent administration, and maintains low production costs for treating a large population or as a preventive measure. Current evidence points to a causal role of misfolded α-synuclein in the development and progression of synucleinopathies. In the past decade, significant progress in active immunization against α-synuclein has been shown both in preclinical animal models and in early clinical development. In this review, we describe the state-of-the-art in active immunization approaches to synucleinopathies, with a focus on advances in Parkinson's disease (PD) and multiple-system atrophy (MSA). We first review preclinical animal models, highlighting their progress in translation to the clinical setting. We then discuss current clinical applications, stressing different approaches taken to address α-synuclein pathology. Finally, we address challenges, trends, and future perspectives of current vaccination programs. © 2015 International Parkinson and Movement Disorder Society. PMID:26260853

    2012-01-01

    Current antiretroviral therapy for HIV-1 infection effectively suppresses but does not eradicate HIV-1. Patients on Highly Active Anti-Retroviral Therapy (HAART) maintain a persistent low-level viremia requiring lifelong adherence to antiretroviral therapies. This viremia may arise from latently infected reservoirs such as resting memory CD4+ T-cells or sanctuary sites where drug penetration is suboptimal. Understanding the mechanisms of HIV latency will help efforts to eradicate the infectio...

  1. Photon activation therapy: a Monte Carlo study on dose enhancement by various sources and activation media

    In the present study, a number of brachytherapy sources and activation media were simulated using MCNPX code and the results were analyzed based on the dose enhancement factor values. Furthermore, two new brachytherapy sources (131Cs and a hypothetical 170Tm) were evaluated for their application in photon activation therapy (PAT). 125I, 103Pd, 131Cs and hypothetical 170Tm brachytherapy sources were simulated in water and their dose rate constant and the radial dose functions were compared with previously published data. The sources were then simulated in a soft tissue phantom which was composed of Ag, I, Pt or Au as activation media uniformly distributed in the tumour volume. These simulations were performed using the MCNPX code, and dose enhancement factor (DEF) was obtained for 7, 18 and 30 mg/ml concentrations of the activation media. Each source, activation medium and concentration was evaluated separately in a separate simulation. The calculated dose rate constant and radial dose functions were in agreement with the published data for the aforementioned sources. The maximum DEF was found to be 5.58 for a combination of the 170Tm source with 30 mg/ml concentration of I. The DEFs for 131Cs and 170Tm sources for all the four activation media were higher than those for other sources and activation media. From this point of view, these two sources can be more useful in photon activation therapy with photon emitter sources. Furthermore, 131Cs and 170Tm brachytherapy sources can be proposed as new options for use in the field of PAT.

  2. ABC of AIDS and Antiretroviral Therapy: Perspectives and Obstacles

    2011-12-01

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 is undoubtedly the primary cause of the acquired immunodeficiency syndrome (AIDS, which is a slow, progressive and degenerative disease of the human immune system. The pathogenesis of HIV-1 is complex and characterized by the interplay of both viral and host factors. Practically every stage in the viral life cycle and every viral gene product is a potential target. Although HAART has made long-term suppression of HIV a reality, drug resistance, drug toxicity, drug penetration, adherence to therapy, low levels of continued viral replication in cellular reservoirs and augmentation of host immune responses are some of the most important challenges that remain to be sorted out. Novel targets for the management of HIV infection have become increasingly relevant in view of extensive drug resistance, side effects and high pill burden of some of the conventional anti-retroviral agents. These agents include chemokine receptor antagonists, integrase inhibitors, maturation inhibitors, zinc finger inhibitors, pharmacological CDK inhibitors, Tate-TAR interaction inhibitors, anti-CD4 monoclonal antibodies and antisense oligonucleotides. In this review we gave a basic overview of the virology of HIV-1 including the functions of the different HIV-1 proteins required for effective viral replication, various obstacles to HIV therapy, perspectives related to the issues that are critical in determining the success or failure of HAART, current methods for detecting HIV-1 drug resistance and various novel targets for the management of HIV infection

  3. Effects of Active Versus Passive Group Music Therapy on Preadolescents with Emotional, Learning, and Behavioral Disorders.

    Montello; Coons

    1999-01-01

    This study attempted to compare the behavioral effects of active, rhythm-based group music therapy vs. those of passive, listening-based group music therapy on preadolescents with emotional, learning, and behavioral disorders. It was hypothesized that preadolescents who participated in active music therapy would more significantly improve target behaviors than those involved in passive music therapy. Achenbach's Teacher Report Form (TRF) was used to confirm changes among subjects in attention, motivation, and hostility as rated by homeroom teachers. Twelve music therapy sessions were conducted over a 4-month period with three different groups of subjects (n = 16), with two groups participating in active music therapy and the other receiving passive music therapy. Results indicate that subjects improved significantly after receiving both music therapy interventions. The most significant change in subjects was found on the aggression/hostility scale. These results suggest that group music therapy can facilitate the process of serf-expression in emotionally disturbed/learning disabled adolescents and provide a channel for transforming frustration, anger, and aggression into the experience of creativity and self-mastery. Discussion of results also includes recommendations for chousing one music therapy approach over another based on personality types and/or clinical diagnoses of subjects. PMID:10519828

    Full Text Available Objective : The main objective of the current study is to monitor the auditory status in a group of adults with AIDS, receiving Highly Active Antiretroviral Therapy (HAART (3TC -lamivudine, D4T - stavudine, and efavirenz in a hospital outpatient clinic in Gauteng. A total sample of 54 adults (between the ages of 18 and 50 years in the experimental group and 16 in the control group were assessed prospectively following a repeated measures design. All participants were assessed at baseline at three months, and at six months into the treatment. Materials and Methods : The participants underwent case history interviews and medical record reviews, otoscopy, and tympanometry, as well as conventional pure tone audiometry and distortion product otoacoustic emission testing. Both descriptive and inferential statistics were used to analyze the data. Results : On audiological monitoring, statistically significant changes (P<0.05 were established, only in the experimental group, for pure tone audiometry - with clinically significant changes found at high frequencies. Statistically significant changes with clinically significant changes were obtained for distortion product otoacoustic emissions (DPOAEs in the experimental group, particularly at high frequencies - implying subclinical hearing function changes; while lack of statistically significant changes with no clinically significant changes were found in the control group. The subclinical hearing changes in the experimental group were also evident in the findings of the subclinical hearing loss group, who, although they had normal pure tone function after six months of follow up, presented with clinical changes on DPOAEs at 6 and 8 kHz. Conclusions : Findings highlight the need for closer monitoring of the effects of antiretroviral drugs (ARVs on hearing, through the use of more sensitive tools of assessment when conducting drug trials.

  5. Baroreflex Activation Therapy in Heart Failure With Reduced Ejection Fraction: Available Data and Future Perspective.

    Halbach, Marcel; Fritz, Thorsten; Madershahian, Navid; Pfister, Roman; Reuter, Hannes

    2016-04-01

    Progression of heart failure with reduced ejection fraction (HFrEF) is promoted by sympathovagal imbalance. Baroreflex activation therapy, i.e., electrical stimulation of baroreceptors at the carotid sinus, can restore sympathovagal balance. Large animal studies of baroreflex activation therapy revealed improvements in cardiac function, susceptibility to ventricular arrhythmias, and a survival benefit as compared to untreated controls. Recently, the first randomized and controlled trial of optimal medical and device therapy alone or plus baroreflex activation therapy in patients suffering from HFrEF was published. It demonstrated a reasonable safety profile in this severely ill patient population. Moreover, the study found significant improvements in New York Heart Association class, quality of life, 6-min walk distance, and NT-proBNP levels. This review provides an overview on baroreflex activation therapy for the treatment of HFrEF-from the concept and preclinical findings to most recent clinical data and upcoming trials. PMID:26879389

    Most medical treatments of Parkinson's disease (PD) are aimed at the reduction of motor symptoms. However, even when motor improvements are evident, patients often report a deterioration of their daily lives. Thus, to achieve a global improvement in personal well-being, not only drugs, but also complementary therapies, such as physical exercise, occupational and speech therapy, and active music therapy, have been used. We hypothesized that theater could reduce clinical disability and improve ...

    Therapy with monoclonal antibodies to tumor necrosis factor (TNF)-α and the interleukin (IL)-12/23 p40 subunit has significantly improved the clinical outcome of patients with psoriasis. These antibodies inhibit the effects of the target cytokines and thus the major concern during their use is the induction of excessive immunosuppression. Recent studies evaluating the long-term efficacy and safety of biologic therapy in psoriasis have shown no significant appearance of serious adverse effects including infections and malignancies. However, the immunological consequence and the mechanism by which the blockade of a single cytokine by biologics can successfully control the activity of psoriasis remain unclear. In the current study, we investigated the effect of biologic therapy on cytokine production of various lymphocytes and on the activity of monocytes and neutrophils in psoriatic patients. Neutrophils, monocytes and T cells were purified from heparinized peripheral venous blood by Ficoll density gradient centrifugation, and γ-interferon, TNF-α and IL-17 production from lymphocytes was measured by flow cytometer. The activation maker of neutrophils and the activated subsets of monocytes were also analyzed. Biologic therapy induced no significant changes in the cytokine production by lymphocytes from the skin and gut-homing T cells. However, neutrophil activity and the ratio of activated monocyte population increased in severely psoriatic patients were normalized in psoriatic patients receiving biologic therapy. The present study showed that biologic therapy ameliorates clinical symptoms and controls the immune response in patients with psoriasis. PMID:25099154

    1983-11-17

    In a multicenter single-blind study on 60 patients with unilateral gonarthrosis the efficacy and tolerance of etofenamate cream were compared to a commonly used ointment containing salicylic acid and other ingredients. With respect to therapeutic success etofenamate was superior to the control medication. Mobility and circumference of the knee joint as well as pain parameters improved more rapidly in the etofenamate group, whereby the difference between both groups frequently was statistically significant. With the control medication therapy failed in three cases, with etofenamate cream clinical symptoms improved in all patients. With the exception of a transient local reddening of the skin in one patient of the etofenamate group no adverse drug reactions were observed. PMID:6654301

    Goeckerman's therapy (GT) of psoriasis is based on daily application of pharmacy grade coal tar on affected skin with subsequent exposure to UV light. Goeckerman's therapy is still the first line therapy of psoriasis in the Czech Republic because of its low cost and long-term efficacy. Disturbances in angiogenic activity are characteristic for the immunopathogenesis of psoriasis. An abnormal spectrum of cytokines, growth factors and proangiogenic mediators is produced by keratinocytes and inflammatory cells in patients suffering from the disease. The aim of this study was to evaluate the influence of GT of psoriasis on angiogenic activities by comparing serum levels of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in 44 patients with psoriasis in peripheral blood samples collected before and after therapy. It was found that the angiogenic potential which is abnormally increased in patients with psoriasis is significantly alleviated by GT.

  18. Ritonavir blocks AKT signaling, activates apoptosis and inhibits migration and invasion in ovarian cancer cells

    Weaver Donald W

    2009-04-01

    Full Text Available Abstract Background Ovarian cancer is the leading cause of mortality from gynecological malignancies, often undetectable in early stages. The difficulty of detecting the disease in its early stages and the propensity of ovarian cancer cells to develop resistance to known chemotherapeutic treatments dramatically decreases the 5-year survival rate. Chemotherapy with paclitaxel after surgery increases median survival only by 2 to 3 years in stage IV disease highlights the need for more effective drugs. The human immunodeficiency virus (HIV infection is characterized by increased risk of several solid tumors due to its inherent nature of weakening of immune system. Recent observations point to a lower incidence of some cancers in patients treated with protease inhibitor (PI cocktail treatment known as HAART (Highly Active Anti-Retroviral Therapy. Results Here we show that ritonavir, a HIV protease inhibitor effectively induced cell cycle arrest and apoptosis in ovarian cell lines MDH-2774 and SKOV-3 in a dose dependent manner. Over a 3 day period with 20 μM ritonavir resulted in the cell death of over 60% for MDAH-2774 compared with 55% in case of SKOV-3 cell line. Ritonavir caused G1 cell cycle arrest of the ovarian cancer cells, mediated by down modulating levels of RB phosphorylation and depleting the G1 cyclins, cyclin-dependent kinase and increasing their inhibitors as determined by gene profile analysis. Interestingly, the treatment of ritonavir decreased the amount of phosphorylated AKT in a dose-dependent manner. Furthermore, inhibition of AKT by specific siRNA synergistically increased the efficacy of the ritonavir-induced apoptosis. These results indicate that the addition of the AKT inhibitor may increase the therapeutic efficacy of ritonavir. Conclusion Our results demonstrate a potential use of ritonavir for ovarian cancer with additive effects in conjunction with conventional chemotherapeutic regimens. Since ritonavir is clinically

  7. Genotypic alteration of HAART-persistent HIV-1 reservoirs in vivo

    Three HIV-1-infected individuals, on virally-suppressive highly active anti-retroviral therapy (HAART), were treated in vivo with anti-retroviral inhibitor intensification and cell stimulatory therapies in attempting to eradicate latent viral reservoirs. Afterwards, the patients ceased all anti-retroviral drugs. Sequences of the V3 region of HIV-1 envelope protein (ENV) from patient peripheral blood mononuclear cell (PBMC) proviral DNA, patient blood plasma viral RNA and virion-associated RNA from viruses amplified by patient cell co-culture, were obtained before, during, and certain times after the clinical regimen. As anticipated, the V3 loop sequencing results indicate diversity in viral strain complexity among the individual patients. However, the detection of unique V3 ENV signature sequences or V3 signatures of low frequency, relative to those observed prior to therapy, indicate that the expression of specific viruses, or viruses of low abundance, can be induced through stimulation in vivo. Furthermore, this stimulation or general immune activation therapy (IAT) approach, consisting of administration of the anti-T-cell receptor antibody, OKT3, and IL-2 in vivo, appeared to have subsequently altered the genotype of the persistent viral reservoir in peripheral blood cells for two of the three patients

  8. Adapted physical activity in the prevention and therapy of osteoporosis

    Bošković Ksenija

    2013-01-01

    Full Text Available Introduction. Osteoporosis, a disease characterized by the progressive loss of bone tissue, is one of the most common complications of aging. Epidemiology. According to some calculations, there were 25% of women and 4% of men older than 50 years with osteoporosis in the world in 2010. It is assumed that the number of patients with osteoporosis will increase by 30% in every 10 years in the 21st century. There are many reasons for that: the world’s population is growing older, diet is getting poorer in vitamins and minerals and physical activity is decreasing. The Quality and Quantity of Bone Tissue. Developing bones are much more responsive to mechanical loading and physical activity than mature bones. This suggests that training in early childhood may be an important factor in the prevention of osteoporosis in later life. It is important to note that the quality of bone achieved by training at younger age cannot be maintained permanently if it is not supported by physical activity later in life. Adapted physical activity represents physical activity individually tailored according to the psychosomatic capabilities of a person and the goal to be achieved. It can be applied at any age in order to maintain strong bones and reduce the risk of fracture. Adapted physical activity is different for men and women, for different age, as well as for the individuals. Aerobic exercises, which lead to an acceleration of breathing, increased heart rate and mild perspiration, as well as resistance exercises and exercises against resistance done by stretching elastic bands, for hands, legs and torso have been proven to increase bone density and improve bone strength. Coordination and balance exercises are important in an individual workout program. An explanation of the action of adapted physical activity is the basis for the theory of control and modulation of bone loss, muscle strength, coordination and balance. Physical activity is very effective in

  9. A pilot study to evaluate the magnitude of association of the use of electronic personal health records with patient activation and empowerment in HIV-infected veterans

    Pierre-Cédric B. Crouch

    2015-03-01

    Full Text Available The HITECH Act signed into law in 2009 requires hospitals to provide patients with electronic access to their health information through an electronic personal health record (ePHR in order to receive Medicare/Medicaid incentive payments. Little is known about who uses these systems or the impact these systems will have on patient outcomes in HIV care. The health care empowerment model provides rationale for the hypothesis that knowledge from an electronic personal health record can lead to greater patient empowerment resulting in improved outcomes. The objective was to determine the patient characteristics and patient activation, empowerment, satisfaction, knowledge of their CD4, Viral Loads, and antiretroviral medication, and medication adherence outcomes associated with electronic personal health record use in Veterans living with HIV at the San Francisco VA Medical Center. The participants included HIV-Infected Veterans receiving care in a low volume HIV-clinic at the San Francisco VA Medical Center, divided into two groups of users and non-users of electronic personal health records. The research was conducted using in-person surveys either online or on paper and data abstraction from medical records for current anti-retroviral therapy (ART, CD4 count, and plasma HIV-1 viral load. The measures included the Patient Activation Measure, Health Care Empowerment Inventory, ART adherence, provider satisfaction, current CD4 count, current plasma viral load, knowledge of current ART, knowledge of CD4 counts, and knowledge of viral load. In all, 40 participants were recruited. The use of electronic personal health records was associated with significantly higher levels of patient activation and levels of patient satisfaction for getting timely appointments, care, and information. ePHR was also associated with greater proportions of undetectable plasma HIV-1 viral loads, of knowledge of current CD4 count, and of knowledge of current viral load.

    [Purpose] The objective of this study was to investigate the effects of mirror therapy combined with exercise tasks on the function of the upper limbs and activities of daily living. [Subjects and Methods] Twenty-five stroke patients who were receiving physical therapy at K Hospital in Gyeonggi-do, South Korea, were classified into a mirror therapy group (n=12) and a conventional therapy group (n=13). The therapies were applied for 30 minutes per day, five times per week, for a total of four weeks. Upper limb function was measured with the Action Research Arm test, the Fugl-Meyer Assessment, and the Box and Block test, and activities of daily living were measured with the Functional Independence Measure. A paired test was performed to compare the intragroup differences between before training and after four weeks of therapy, and an independent t-test was performed to compare the differences between the two groups before and after four weeks of therapy. [Results] In the intragroup comparison, both groups showed significant differences between measurements taken before and after four weeks of therapy. In the intergroup comparison, the mirror therapy group showed significant improvements compared with the conventional therapy group, both in upper limb function and activities of daily living. [Conclusion] The findings of this study demonstrated that mirror therapy is more effective than conventional therapy for the training of stroke patients to improve their upper limb function and activities of daily living.

    Conditionally replicating adenoviruses (CRAds) utilize tissue specific promoters to control the expression of the early genes, E1A and E1B, to preferentially replicate and lyse tumor cells (oncolysis). Previous CRAds used in prostate cancer gene therapy require androgens to activate prostate specific promoters and induce viral replication. Unfortunately, these CRAds have reduced activity in patients on androgen suppressive therapy. We describe a novel prostate specific CRAd generated by fusing the E1A gene to the androgen receptor (AR) cDNA with a point mutation in codon 685 (C685Y). The E1A-AR fusion neutralizes the previously described mutual inhibition of E1A & AR, and the C685Y point mutation alters specificity of steroid ligand binding to the AR, such that both androgens and non-steroidal anti-androgens can activate viral replication. We demonstrate that the mutated E1A-AR retained the ability to function in regulating AR responsive genes and E1A responsive viral genes. In combination therapy of virus, bicalutamide (anti-androgen) and radiation, a profound impact on cell death by viral oncolysis was seen both in vitro and tumor xenografts. To our knowledge, this is the first gene therapy engineered to be enhanced by anti-androgens, and a particularly attractive adjuvant strategy for intensity modulated radiation therapy (IMRT) of high-risk prostate cancers.

  15. Photodynamic therapy for cancer and activation of immune response

    Mroz, Pawel; Huang, Ying-Ying; Hamblin, Michael R.

    2010-02-01

    Anti-tumor immunity is stimulated after PDT for cancer due to the acute inflammatory response, exposure and presentation of tumor-specific antigens, and induction of heat-shock proteins and other danger signals. Nevertheless effective, powerful tumor-specific immune response in both animal models and also in patients treated with PDT for cancer, is the exception rather than the rule. Research in our laboratory and also in others is geared towards identifying reasons for this sub-optimal immune response and discovering ways of maximizing it. Reasons why the immune response after PDT is less than optimal include the fact that tumor-antigens are considered to be self-like and poorly immunogenic, the tumor-mediated induction of CD4+CD25+foxP3+ regulatory T-cells (T-regs), that are able to inhibit both the priming and the effector phases of the cytotoxic CD8 T-cell anti-tumor response and the defects in dendritic cell maturation, activation and antigen-presentation that may also occur. Alternatively-activated macrophages (M2) have also been implicated. Strategies to overcome these immune escape mechanisms employed by different tumors include combination regimens using PDT and immunostimulating treatments such as products obtained from pathogenic microorganisms against which mammals have evolved recognition systems such as PAMPs and toll-like receptors (TLR). This paper will cover the use of CpG oligonucleotides (a TLR9 agonist found in bacterial DNA) to reverse dendritic cell dysfunction and methods to remove the immune suppressor effects of T-regs that are under active study.

  16. Chlorotoxin: Structure, activity, and potential uses in cancer therapy.

    Ojeda, Paola G; Wang, Conan K; Craik, David J

    2016-01-01

    Chlorotoxin is a disulfide-rich stable peptide from the venom of the Israeli scorpion Leiurus quinquestriatus, which has potential therapeutic applications in the treatment of cancer. Its ability to preferentially bind to tumor cells has been harnessed to develop an imaging agent to help visualize tumors during surgical resection. In addition, chlorotoxin has attracted interest as a vehicle to deliver anti-cancer drugs specifically to cancer cells. Given its interesting structural and biological properties, chlorotoxin also has the potential to be used in a variety of other biotechnology and biomedical applications. Here, we review the structure, activity and potential applications of chlorotoxin as a drug design scaffold. PMID:26418522

    2013-12-01

    Full Text Available The choice of the theme for this research was determined by the combination of two of my professional interests: occupational therapy, and physical education and sports. The aim and tasks of this paper are to identify and contribute to the introduction of occupational therapy in the freedom-deprived persons in penitentiaries, following their involvement in leisure time athletic activities. The study was conducted at the Bacau Penitentiary for minors and youths, over the course of three months, March-May, 2013, the group of subjects being composed of 18 minors. The initial hypothesis presumes that the use of the occupational therapy intervention in the minor freedom-deprived persons contributes to a more effective use of their leisure time performing activities that would give them satisfactions, improving their health and quality of life. The research consisted in applying an intervention with the help of several students, who over the course of three months assessed the freedom-deprived penitentiary minors, conceived an intervention plan for the leisure time athletic activities, and applied it. The results obtained after the initial assessment indicated the existence of certain occupational problems in the area of leisure time athletic activities, in the studied subjects. After the occupational therapy intervention, a questionnaire was applied to assess the effectiveness of the intervention. The development of the study and the interpretation of the results have lead to the following conclusions: One can say that the use of occupational therapy for the freedom-deprived minors lead to the improvement of their quality of life, thus confirming the initial hypothesis. The regular practice of athletic activities leads to a healthy life pattern and to structuring your leisure time through activities that have a positive effect, forming self-efficacy beliefs and competences, and have a direct relation with self-esteem, overshadowing the passive

  19. Activity balance of a nuclear medicine therapy ward at a 250 MBQ limit of dismissal

    A consistant utilisation of the raise of the limit of dismissal from 95 to 250 MBq 131I increases the number of radioiodine therapies by a factor of 2.5. The fraction of the activity administered to patients that is excreted until dismissal averages to 72%, including 0.4% in the waste, 0.2% in contaminations of laundry and dishes, and <0.1% airborne activity. 14% of the activity decay in the patient during this time. The remaining 14% leave the therapy facility with the patient and add to 99.9% to the activity polluting the environment. This part causes the highest risk and necessitates a detailled instruction procedure to the patient. (orig.)

  20. Real-Time Assessment of Autonomic Nerve Activity During Adaptive Servo-Ventilation Support or Waon Therapy.

    Imamura, Teruhiko; Kinugawa, Koichiro; Nitta, Daisuke; Komuro, Issei

    2016-07-27

    Adaptive servo-ventilation support and Waon therapy are recently developed non-pharmacological and noninvasive therapies for patients with heart failure refractory to guideline-directed medical therapy. These therapies decrease both preload and afterload, increase cardiac output, and appear to ameliorate autonomic nerve activity. However, the time course of autonomic nerve activity during these therapies remains unclear. We performed heart rate variability analysis using the MemCalc power spectral density method (MemCalc system; Suwa Trust Co, Tokyo) to assess autonomic nerve activity during adaptive servo-ventilation support and Waon therapy in two different cases and determined the time course of autonomic nerve activity during these therapies. During both therapies, we found a drastic increase in parasympathetic nerve activity and continuous suppression of sympathetic nerve activity. Heart rate variability analysis using the MemCalc method may be promising for the assessment of the efficacy of various treatments, including adaptive servo-ventilation support and Waon therapy, from the viewpoint of autonomic nerve activity.

    2010-01-01

    Commercially produced sterile green bottle fly Lucilia sericata maggots are successfully employed by practitioners worldwide to clean a multitude of chronic necrotic wounds and reduce wound bacterial burdens during maggot debridement therapy (MDT). Secretions from the maggots exhibit antimicrobial...... activity along with other activities beneficial for wound healing. With the rise of multidrug-resistant bacteria, new approaches to identifying the active compounds responsible for the antimicrobial activity within this treatment are imperative. Therefore, the aim of this study was to use a novel approach...

    2004-06-01

    Inhibition of ribonucleotide reductase (RR) has gained attention as a potential strategy for HIV-1 therapy through the success of hydroxyurea (HU) to potentiate the activity of the nucleoside reverse transcriptase inhibitor (NRTI) didanosine (ddI) in clinical trials. However, the use of HU has been limited by its development of hematopoietic toxicity. In this study, the novel RR inhibitors didox (DX; 3,4-dihydroxybenzohydroxamic acid), and trimidox (TX; 3,4,5-trihydroxybenzamidoxime) were evaluated along with HU for anti-retroviral efficacy in LPBM5-induced retro-viral disease (MAIDS) both as monotherapeutic regimens and in combination with the guanine containing NRTI abacavir (ABC). Anti-retroviral drug efficacy was determined by measuring inhibition of splenomegaly, hypergammaglobulinemia, and splenic levels of proviral DNA. In this study, all RRIs tested showed the ability to improve the efficacy of ABC in the MAIDS model by reducing splenomegaly, hypergammaglobulinemia, and splenic proviral DNA levels. PMID:15130534

    2010-01-01

    BACKGROUND: The impact of antiretroviral therapy (ART) interruption in HIV-hepatitis B virus (HBV)-coinfected patients was examined in the Strategic Management of AntiRetroviral Therapy (SMART) study. METHODS: Plasma HBV DNA was measured in all hepatitis B surface antigen-positive (HBV.......0002), nondetectable HBV DNA at baseline (P = 0.007), and black race (P = 0.03). Time to ART reinitiation was shorter (7.5, 15.6, and 17.8 months; P < 0.0001) and proportion reinitiating greater (62.5, 46.5, and 39.7%; P = 0.0002) among HBV-positive participants as compared with hepatitis C virus-positive and non-HBV/hepatitis...... C virus participants in the drug conservation arm. No hepatic decompensation events occurred among HBV-positive participants in either arm. CONCLUSION: HBV DNA rebound following ART interruption is common and may be associated with accelerated immune deficiency in HIV-HBV-coinfected patients....

    2012-11-01

    Full Text Available Purpose of the study: HIV-1-infected patients have elevated levels of immune activation and systemic inflammatory markers which are partially strong predictors of disease progression or are associated with increased cardiovascular risk. The dependency of anti-retroviral treatment (ART, the usage of NNRTI or PI-based and the application of non-nuc regimens is analysed here on the basis of a dataset (Chronic Inflammation Dependency on TREatment: CIDRE cohort from 1500 patients in Berlin. Methods: In a retrospective analysis we compared relative CD4+ cell counts, viral load, relative CD8+CD38+DR-and CD3+DR+cells, concentration of high-sensitivity C-reactive protein (hsCRP and interleukin-6 (IL-6 in therapy-naïve or treated patients dependent on usage or non-usage of NUCs, PI or NNRTI. Statistics were performed with R (R Core Team; 2012; R: A language and environment for statistical computing using Wilcoxon rank sum test in two-sided analysis. Summary of results: As to expect, ART-naïve patients (n=190 had significantly higher viral loads and lower CD4+cell counts (p: both<0.05 and showed higher activation levels than treated patient (CD8+CD38+DR- and CD3+DR+both<0.05. But no significant difference was calculated for hsCRP or IL-6. Nuc-sparing regimen (n=46 did not show any distinction compared to nuc-containing therapies (n=1249 for the analysed parameters. Significant differences were detected for PI-regimen (n=711 with lower CD4+ cell counts and higher activation (CD8+38+DR-, CD3+DR+ and IL-6 (p: all<0.05 but not for hsCRP (p=0.39. The opposite was true for NNRTI-based therapies (n=445 with higher CD4+ cell percentages and lower activation and inflammation markers (p: all<0.05 and as well no difference in hsCRP (p=0.97 compared with all other treated patients. Conclusions: The lack of differences between therapy-naïve patients and patients on ART for inflammation markers may be due to the relative good immunological state of the first group

  5. Absence of osteoporosis in an adult population undergoing combined immunosuppressive therapy for chronic active hepatitis

    Thirty adult patients who had received 1-20 years of combined immunosuppressive therapy (CIT) for chronic active hepatitis (CAH) underwent dual-photon absorptiometry (DPA) of L-2 through L-4 CIT consisted of azathioprine and prednisone supplemented and calcium and vitamin D. Osteoporosis is known to occur in patients with CAH, and in other clinical settings prednisone therapy has been shown to induce osteoporosis. For these 30 adult CAH patients undergoing CIT, absorptiometric measurements did not differ significantly from those in age- and sex-matched normal controls. CIT therapy for CAH may have arrested the long-term loss of bone mineral often produced by CAH. The authors' hypothesize that a combined azathioprine and prednisone regimen with reduced corticosteroid requirements was responsible for this favorable outcome

    @@ Antiretroviral therapy is a key determinant in the treatment and prevention of human immunodeficiency virus (HIV) infection. Initial treatment for patients with HIV infection generally includes two nucleoside reverse transcriptase inhibitors (NRTI) and a protease inhibitor (PI) or a nonnucleoside reverse transcriptase inhibitor (NNRTI). The combination antiretroviral therapy (refers to highly active antiretroviral therapy or HAART) showed a significant effect upon reducing morbidity and mortality of HIV disease. Cao and colleagues1 began the clinical application of HAART in 1999 and completed the first clinical trial in China using a combination of two NRTIs and one PI. The result in using combivir (AZT+3TC) and indinavir (2 NRTIs+1 PI) are consistent with those reported in the literature.2 In this study, we report the first virological and immunological outcomes in HIV infected Chinese patients treated with a combination of didanosine, stavudine and nevirapine (2 NRTIs+1 NNRTI) for 52 weeks.

  7. Activation of photodynamic therapy in vitro with Cerenkov luminescence generated from Yttrium-90 (Conference Presentation)

    Hartl, Brad A.; Hirschberg, Henry; Marcu, Laura; Cherry, Simon R.

    2016-03-01

    Translation of photodynamic therapy to the clinical setting has primarily been limited to easily accessible and/or superficial diseases where traditional light delivery can be performed noninvasively. Cerenkov luminescence, as generated from medically relevant radionuclides, has been suggested as a means to deliver light to deeper tissues noninvasively in order to overcome this depth limitation. We report on the use of Cerenkov luminescence generated from Yttrium-90 as a means to active the photodynamic therapy process in monolayer tumor cell cultures. The current study investigates the utility of Cerenkov luminescence for activating both the clinically relevant aminolevulinic acid at 1.0 mM and also the more efficient photosensitizer TPPS2a at 1.2 µM. Cells were incubated with aminolevulinic acid for 6 hours prior to radionuclide addition, as well as additional daily treatments for three days. TPPS2a was delivered as a single treatment with an 18 hour incubation time before radionuclide addition. Experiments were completed for both C6 glioma cells and MDA-MB-231 breast tumor cells. Although aminolevulinic acid proved ineffective for generating a therapeutic effect at any activity for either cell line, TPPS2a produced at least a 20% therapeutic effect at activities ranging from 6 to 60 µCi/well for the C6 cell line. Current results demonstrate that it may be possible to generate a therapeutic effect in vivo using Cerenkov luminescence to activate the photodynamic therapy process with clinically relevant photosensitizers.

    The objective of this study is to evaluate the effect of interdisciplinary therapy in the parameters of the oxidative stress and the anti-inflammatory responses of obese adolescents. We selected 57 participants, who were randomly divided into 2 groups: interdisciplinary therapy group and a control group. After 6 months of intervention, 17 participants of the interdisciplinary therapy group and 8 of the control group returned for re-evaluation. The interdisciplinary therapy group participated in a treatment with 4 weekly sessions of exercise, a weekly group therapy session and a weekly nutritional education session. Blood parameters of oxidative stress and anti-inflammatory response were evaluated. The results demonstrated that there were significant increases in the interdisciplinary therapy group for superoxide dismutase activity (6.56 ± 3.22 to 11.40 ± 7.49) and ferric-reducing antioxidant potential concentration (532.91 ± 106.48 to 573.25 ± 112.57), although adiponectin levels did not reduce (40.9 ± 29.34 to 49.05 ± 41.22). A significant decrease in nitrite levels was also found (14.23 ± 8.48 to 11.45 ± 6.05). In the control group, significant reduction was found in adiponectin (31.56 ± 18.88 to 18.01 ± 11.66). This study suggests that interdisciplinary therapy for 6 months was effective in improving the anti-inflammatory responses and the antioxidant defences in obese adolescents. PMID:26367325

  12. Somatomedin activity before and after chelation therapy in lead-intoxicated children

    Rohn, R.D.; Hill, J.R.; Shelton, J.E.

    1982-11-01

    Somatomedin activity was measured in 21 lead-intoxicated children to determine whether plumbism interferes with the processes of statural (bone) growth. Somatomedin activity was measured both by the rabbit coastal cartilage bioassay and by radioimmunoassay of somatomedin-C. Compared to values in normal children, both the bioassay and radioimmunoassay somatomedin activity was increased. The degree of body lead burden was so extensive that the 21 study children required chelation therapy. Following EDTA or BAL + EDTA chelation therapy, the overall somatomedin activity of these children with plumbism further increased significantly. In contrast, measures of body lead burden--including blood lead levels--decreased after treatment in all lead-intoxicated youngsters. We conclude that plumbism is associated with increased somatomedin activity. Hence the increased somatomedin activity may explain why clinical experience fails to find any long-term deleterious effect of saturnism on statural (bone) growth. Possible mechanisms underlying the increased somatomedin activity in the lead-intoxicated children remain to be defined.

  13. Monocyte Activation in Immunopathology: Cellular Test for Development of Diagnostics and Therapy

    Ekaterina A. Ivanova

    2016-01-01

    Full Text Available Several highly prevalent human diseases are associated with immunopathology. Alterations in the immune system are found in such life-threatening disorders as cancer and atherosclerosis. Monocyte activation followed by macrophage polarization is an important step in normal immune response to pathogens and other relevant stimuli. Depending on the nature of the activation signal, macrophages can acquire pro- or anti-inflammatory phenotypes that are characterized by the expression of distinct patterns of secreted cytokines and surface antigens. This process is disturbed in immunopathologies resulting in abnormal monocyte activation and/or bias of macrophage polarization towards one or the other phenotype. Such alterations could be used as important diagnostic markers and also as possible targets for the development of immunomodulating therapy. Recently developed cellular tests are designed to analyze the phenotype and activity of living cells circulating in patient’s bloodstream. Monocyte/macrophage activation test is a successful example of cellular test relevant for atherosclerosis and oncopathology. This test demonstrated changes in macrophage activation in subclinical atherosclerosis and breast cancer and could also be used for screening a panel of natural agents with immunomodulatory activity. Further development of cellular tests will allow broadening the scope of their clinical implication. Such tests may become useful tools for drug research and therapy optimization.

  15. The relative merits of therapies being developed to tackle inappropriate ('self'-directed) complement activation.

    Antwi-Baffour, Samuel; Kyeremeh, Ransford; Adjei, Jonathan Kofi; Aryeh, Claudia; Kpentey, George

    2016-12-01

    The complement system is an enzyme cascade that helps defend against infection. Many complement proteins occur in serum as inactive enzyme precursors or reside on cell surfaces. Complement components have many biologic functions and their activation can eventually damage the plasma membranes of cells and some bacteria. Although a direct link between complement activation and autoimmune diseases has not been found, there is increasing evidence that complement activation significantly contributes to the pathogenesis of a large number of inflammatory diseases that may have autoimmune linkage. The inhibition of complement may therefore be very important in a variety of autoimmune diseases since their activation may be detrimental to the individual involved. However, a complete and long-term inhibition of complement may have some contra side effects such as increased susceptibility to infection. The site of complement activation will, however, determine the type of inhibitor to be used, its route of application and dosage level. Compared with conventional drugs, complement inhibitors may be the best option for treatment of autoimmune diseases. The review takes a critical look at the relative merits of therapies being developed to tackle inappropriate complement activation that are likely to result in sporadic autoimmune diseases or worsen already existing one. It covers the complement system, general aspects of complement inhibition therapy, therapeutic strategies and examples of complement inhibitors. It concludes by highlighting on the possibility that a better inhibitor of complement activation when found will help provide a formidable treatment for autoimmune diseases as well as preventing one.

    The identification of somatic activating mutations in JAK2 1–4 and in the thrombopoietin receptor (MPL) 5 in the majority of myeloproliferative neoplasm (MPN) patients led to the clinical development of JAK2 kinase inhibitors 6,7 . JAK2 inhibitor therapy improves MPN-associated splenomegaly and systemic symptoms, but does not significantly reduce or eliminate the MPN clone in most MPN patients. We therefore sought to characterize mechanisms by which MPN cells persist despite chronic JAK2 inhi...

    1. Acute intermittent porphyria (AIP) is sometimes termed a 'pharmacogenetic' disease. patients with genetic deficiency of the enzyme porphobilinogen deaminase are liable to develop acute attacks of porphyria if exposed to a variety of drugs. 2. Two patients are reported who had no evidence of deficiency of erythrocyte porphobilinogen deaminase yet developed typical attacks of AIP while on anticonvulsant therapy. 3. Normal activity of erythrocyte porphobilinogen deaminase does not completely ...

    Drug interactions with immunosuppressive drugs are a major problem associated with protease inhibitor-based antiviral triple therapy for hepatitis C virus (HCV) reinfection after liver transplantation. In this retrospective cohort study, we analyzed biomarkers of the immunosuppressive effects of cyclosporine A (CSA) by quantifying nuclear factor of activated T cells (NFAT)-regulated gene expression during telaprevir (TVR) therapy in 5 liver transplant patients. Furthermore, dose adjustments and blood concentrations of CSA as well as the clinical course were analyzed. We observed a clear impact of TVR not only on doses and blood concentrations but also on the immunosuppressive effects of CSA. Despite apparently adequate CSA trough concentrations, the CSA peak concentration decreased to 68% (range = 44%-90%). This was associated with a 1.9-fold (1.6- to 4.1-fold) increase in the residual gene activity of NFAT-regulated genes, which indicated reduced immunosuppressive activity of CSA with TVR co-medication. The median dose of CSA was reduced to 25% (range = 16%-48%) and 31% (range = 22%-64%) after 1 and 2 weeks, respectively. The CSA drug clearance was reduced to 38.7% (range = 31.0%-49.4%). We report excellent antiviral efficacy. At the end of the observation period, all patients were HCV RNA-negative (1 patient at 18 weeks, 1 patient at 12 weeks, and 3 patients at 4 weeks after the end of therapy). Safety was acceptable, with mild acute rejection and reactivation of cytomegalovirus being the most serious adverse events. One patient with histologically proven recurrent cholestatic hepatitis before therapy underwent retransplantation during the course of antiviral therapy. In conclusion, the immunomonitoring of NFAT-regulated gene expression indicated reduced immunosuppressive activity of CSA during antiviral therapy with TVR in our cohort of liver transplant patients. Thus, the immunosuppressive effects of CSA may be overestimated if one is looking

  6. Activities in connection with quality assurance in radiation therapy performed in Argentina: physical aspects

    Gonzalez, R.O.

    1984-06-01

    Quality assurance in radiotherapy is performed in different ways in Argentina than in other countries. A part of this program is carried out by the Secondary Standard Dosimetry Laboratory (SSDL-WHO/IAEA), which is a part of the Atomic Energy Commission. This laboratory organizes TLD postal intercomparison; calibrates and checks radiotherapy units and dosimeters; gives education in the physics of radiotherapy; has collaborated in the production of rules for the operation of radiation therapy units and maintains the application of these rules. A description of the activities of the SSDL and a brief explanation about the other activities, the present situation and future plans are discussed.

    Matrix metalloproteinases are shown to be involved in the pathogenesis of tuberculosis inflammation. In the early stages of BCG-granuloma formation in mouse liver and lungs, the serum levels of matrix metalloproteinases 2 and 7 increased by 4.5 times and remained unchanged while the pathology developed. Antimycobacterial therapy with isoniazid reduced enzyme activity almost to the level of intact control. The decrease in activity of matrix metalloproteinases 2 and 7 that play the most prominent role in the development of destructive forms of tuberculosis is of great therapeutic importance.

    We evaluated the clinical significance of indoleamine 2,3-dioxygenase (IDO) during fulvestrant therapy for aromatase inhibitor (AI)-resistant metastatic breast cancer. IDO activity can be measured by the tryptophan (Trp)/kynurenine (Kyn) ratio. Trp and Kyn were measured with high performance liquid chromatography (HPLC). Patients with AI resistant metastatic breast cancer had a 28.6% response rate to fulvestrant therapy, and the clinical benefit rate was 76.2%. AI-resistant metastatic breast cancer patients with distant metastases had a lower serum Trp/Kyn level than patients who had local recurrences. During fulvestrant therapy, IDO activity significantly decreased in the fulvestrant responder group compared to that in the fulvestrant non-responder group. During fulvestrant therapy, the IDO activity correlated with the number of metastatic lesions. These results suggest that measuring the Trp/Kyn ratio is useful for evaluating immunological metastatic status during endocrine therapy. PMID:26489554

  9. Active Theater as a Complementary Therapy for Parkinson's Disease Rehabilitation: A Pilot Study

    Full Text Available Most medical treatments of Parkinson's disease (PD are aimed at the reduction of motor symptoms. However, even when motor improvements are evident, patients often report a deterioration of their daily lives. Thus, to achieve a global improvement in personal well-being, not only drugs, but also complementary therapies, such as physical exercise, occupational and speech therapy, and active music therapy, have been used. We hypothesized that theater could reduce clinical disability and improve the quality of life of PD patients (primary end points more efficiently than other complementary therapies because (1 in order to impersonate a character, patients are forced to regain the control of their bodies; and (2 while being part of a group, patients have a high degree of social interaction. The need to regain the control of their bodies and their social functioning is very likely to deeply motivate patients. To assess this hypothesis, we ran a randomized, controlled, and single-blinded study that lasted 3 years, on 20 subjects affected by a moderate form of idiopathic PD, in stable treatment with L-dopa and L-dopa agonists, and without severe sensory deficits. Ten patients were randomly assigned to an active theater program (in which patients were required to participate, while the others underwent physiotherapy (control group, the most common nonpharmacological treatment for PD rehabilitation. Patients of both groups were evaluated at the beginning of each year, using five clinical rating scales (Unified ParkinsonParkinson'ss Disease Rating Scale [UPDRS], Schwab and England Scale, ParkinsonParkinson'ss Disease Quality of Life [PDQ39] Scale, Epworth Sleepiness Scale, and Hamilton Depression Rating Scale. The theater patients showed progressive improvements and, at the end of the third year, they showed significant improvements in all clinical scales. Conversely, the control patients did not exhibit significant ameliorations with time. Thus, the
