    Full Text Available Strategies to develop a functional cure for HIV infection will likely require boosting of effector T cell responses to eliminate reactivated, latently infected cells. We have recently explored an assay for assessing antigen-specific regulation of T cell proliferation, which was related to clinical progression in untreated patients and to vaccine efficacy in two trials of therapeutic Gag-based vaccines. We here expand the same assay to further investigate regulation mediated by various inhibitory pathways. Peripheral blood mononuclear cells from 26 asymptomatic HIV-infected, antiretroviral therapy-naïve patients were stimulated with Gag and Env overlapping peptide panels for 5 days. Monoclonal antibodies (mAbs blocking inhibitory mediators interleukin (IL 10, transforming growth factor (TGF β, programmed death ligand (PD-L 1 and herpes virus entry mediator (HVEM were added to parallel cultures. Functional T cell regulation (FTR was defined as the difference in proliferation between stimulated cultures with and without blocking mAbs. FTR was detected in 54% of patients. Blockade of IL-10/PD-L1 and IL10/TGF-β detected all cases with Gag- and Env-associated FTR, respectively. In accordance with previous findings, isolated Env FTR was associated with higher plasma HIV RNA and lower CD4 counts, while patients with both Gag and Env FTR also had higher Gag- and Env-specific proliferative CD8+ T cell responses. There was no association between FTR and frequencies of activated regulatory T cells. In conclusion, we observed substantial heterogeneity in FTR between patients, inhibitory pathways and HIV antigens. FTR may help to individualize immunomodulation and warrants further assessment in clinical immunotherapy trials.

    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 The purpose of this study was to assess the possible correlation between Brucella and HIV infections. Iran is a country where HIV infection is expanding and Brucellosis is prevalent. In the present study, 184 HIV infected patients were assigned and for all of them HIV infection was confirmed by western blot test. In order to identify the prevalence rate of Brucella infection and systemic brucellosis in these subjects, sera samples were obtained and Brucella specific serological tests were performed to reveal antibody titers. Detailed history was taken and physical examination was carried out for all of patients. 11 (6% subjects had high titers but only 3 of them were symptomatic. Most of these subjects were injection drug user (IDU men and one was a rural woman. Considering both prevalence rates of Brucella infection (3% and symptomatic brucellosis (0.1% in Iran, our HIV positive patients show higher rates of Brucella infection and systemic brucellosis. Preserved cellular immunity of participants and retention of granulocytes activity may explain this poor association; whereas other explanations such as immunological state difference and non-overlapping geographical distribution of the 2 pathogens have been mentioned by various authors.

    Full Text Available Acquired immune deficiency syndrome (AIDS is an immune system disease caused by the human immunodeficiency virus (HIV. The purpose of this review is to investigate the correlation between an immune system destroyed by HIV and the frequency of pneumonia. Observational studies show that respiratory diseases are among the most common infections observed in HIV-infected patients. In addition, pneumonia is the leading cause of morbidity and mortality in HIV-infected patients. According to articles in literature, in addition to antiretroviral therapy (ART or highly active antiretroviral therapy (HAART, the use of prophylaxis provides favorable results for the treatment of pneumonia. Here we conduct a systematic literature review to determine the pathogenesis and causative agents of bacterial pneumonia, tuberculosis (TB, nontuberculous mycobacterial disease, fungal pneumonia, Pneumocystis pneumonia, viral pneumonia and parasitic infections and the prophylaxis in addition to ART and HAART for treatment. Pneumococcus-based polysaccharide vaccine is recommended to avoid some type of specific bacterial pneumonia.

    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.

    CT examinations of the liver in HIV-infected patients show more frequent pathological findings. The extended spectrum of differential diagnosis and atypical manifestations of disorders in immunodeficient patients needs to be considered in the interpretation of CT scans. Difficulties in the differential diagnosis of focal hepatic lesions in HIV-infected patients are demonstrated in the following. Besides the relatively common findings in HIV-infection such as hepato- or hepatosplenomegalia, lymphoma, and inflammatory changes of the bowel an infection with Cryptococcus neoformans, hepatitis, and local steatosis of the liver are discussed as the rare causes for suspect computertomographic findings in the live of HIV-infected patients.

    2016-04-01

    The advent of combination antiretroviral drug regimens has transformed HIV infection from a fatal illness into a manageable chronic condition. All patients with HIV infection should be considered for antiretroviral therapy, regardless of CD4 count or HIV viral load, for individual benefit and to prevent HIV transmission. Antiretroviral drugs affect HIV in several ways: entry inhibitors block HIV entry into CD4 T cells; nucleotide and nucleoside reverse transcriptase inhibitors prevent reverse transcription from RNA to DNA via chain-terminating proteins; nonnucleoside reverse transcriptase inhibitors prevent reverse transcription through enzymatic inhibition; integrase strand transfer inhibitors block integration of viral DNA into cellular DNA; protease inhibitors block maturation and production of the virus. Current guidelines recommend six combination regimens for initial therapy. Five are based on tenofovir and emtricitabine; the other uses abacavir and lamivudine. Five include integrase strand transfer inhibitors. HIV specialists should assist with treating patients with complicated HIV infection, including patients with treatment-resistant HIV infection, coinfection with hepatitis B or C virus, pregnancy, childhood infections, severe opportunistic infections, complex drug interactions, significant drug toxicity, or comorbidities. Family physicians can treat most patients with HIV infection effectively by choosing appropriate treatment regimens, monitoring patients closely, and retaining patients in care. PMID:27092564

    2016-01-01

    Talaromyces (Penicillium) marneffei is an important pathogenic thermally dimorphic fungus causing systemic mycosis in Southeast Asia. The clinical significance of T. marneffei became evident when the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome epidemic arrived in Southeast Asia in 1988. Subsequently, a decline in the incidence of T. marneffei infection among HIV-infected patients was seen in regions with access to highly active antiretroviral therapy and other control measures for HIV. Since the 1990s, an increasing number of T. marneffei infections have been reported among non-HIV-infected patients with impaired cell-mediated immunity. Their comorbidities included primary adult-onset immunodeficiency due to anti-interferon-gamma autoantibodies and secondary immunosuppressive conditions including other autoimmune diseases, solid organ and hematopoietic stem cell transplantations, T-lymphocyte-depleting immunsuppressive drugs and novel anti-cancer targeted therapies such as anti-CD20 monoclonal antibodies and kinase inhibitors. Moreover, improved immunological diagnostics identified more primary immunodeficiency syndromes associated with T. marneffei infection in children. The higher case-fatality rate of T. marneffei infection in non-HIV-infected than HIV-infected patients might be related to delayed diagnosis due to the lack of clinical suspicion. Correction of the underlying immune defects and early use of antifungals are important treatment strategies. Clinicians should be familiar with the changing epidemiology and clinical management of T. marneffei infection among non-HIV-infected patients. PMID:26956447

    Full Text Available We tried to evaluate prevalence and characteristics of Iranian HIV infected patients with retinitis due to opportunistic infections. In this cross sectional study, we evaluated 106 HIV infected patients via indirect ophthalmoscopy and slit lamp examination by 90 lens to find retinitis cases. General information and results of ophthalmologic examination were analyzed. Prevalence of retinitis due to opportunistic infections was 6.6%: cytomegalovirus (CMV retinitis 1.88%, toxoplasmosis retinochoroiditis 1.88% and tuberculosis chorioretinitis 2.83%. CD4 count was higher than 50 cell/µlit in both cases with CMV retinitis. Along with increasing survival in the HIV infected patients, the prevalence of complications such as ocular manifestation due to opportunistic infections are increasing and must be more considered.

  6. Cobalamin binding proteins in patients with HIV infection

    International Nuclear Information System (INIS)

    P-Cobalamins have been reported to be decreased in patients with HIV infection. Because of this, we found it of interest to examine both cobalamin-saturated binding proteins (holo-transcobalamin, holo-TC and holo-haptocorrin, holo-HC) and cobalamin unsaturated binding proteins (apo-transcobalamin, apo-TC and apo-haptocorrin, apo-HC). The results are given as range and (median). Eighteen male HIV-infected patients with plasma cobalamins below 200 pmol/l were studied. We found low concentrations of holo-TC (37-88(47.5)pmol/l) and holo-HC (64-184(135.3)pmol/l). The concentration of apo-TC and apo-HC was increased (480-1730(1025)pmol/l; 70-800(235)pmol/l). It is concluded that, in HIV-infected patients, low plasma cobalamin does not reflect a low concentration of transcobalamin or haptocorrin. In 20 HIV-infected patients and 31 patients with malignant haematological diseases, the TC isopeptide patterns were determined. In the HIV group, an increased frequency of TC isopeptide X was found and the overall distribution of TC isopeptides was significantly different from the reference population (p<0.05). There was no difference between the group of patients with malignant haematological diseases and the reference group. (au)

    Full Text Available Abstract. Tuberculous meningitis (TBM is a devastating disease. TBM occurs more commonly in HIV infected patients. The influence of HIV co-infection on clinical manifestations and outcome of TBM is not well defined. Yet, some differences have been observed and stroke has been recorded to occur more frequently. This study reports on an HIV infected Caucasian female with lung, meningeal tuberculosis and stroke due to a cortical sub-cortical ischemic lesion.TBM was documented in the absence of neurologic symptoms. At the same time, miliary lung TB caused by multi-susceptible Mycobacterium tuberculosis was diagnosed. Anti-TB therapy consisting of a combination of four drugs was administered. The patient improved and was discharged five weeks later. In conclusion, TBM and multiple underling pathologies including HIV infection, as well as other risk factors can lead to a greater risk of stroke. Moreover, drug interactions and their side effects add levels of complexity. TBM must be included in the differential diagnosis of HIV infected patients with stroke and TBM treatment needs be started as soon as possible before the onset of vasculopathy.

    The growing elderly population of HIV-infected patients is leading to a significant epidemiological transition and HIV infection has been proposed as a premature and accelerated aging model rending the individual more susceptible to premature disability. However, the determinants of disability among this emergent population are still lacking. Therefore, the aim of this study is to determine the correlates of prevalent disability in adults ≥50 years with HIV infection. A cross-sectional study of 184 HIV-infected adults receiving ambulatory care in an HIV clinic of a tertiary care, university-affiliated hospital in Mexico City was conducted. Disability for instrumental (IADL) and basic activities of daily living (ADL) was established. Sociodemographic factors, clinical variables, current CD4(+) cell count, and HIV viral load (VL) were tested as potential determinants of disability. Multivariate logistic regression analyses were used to identify the correlates of both types of disability. The mean age was 59.3 years. All participants were receiving highly active antiretroviral therapy. Of participants 17.9% had disability for IADL and 26.1% for ADL. Multivariate logistic regression analyses indicated that being older; having a lower CD4(+) cell count, and having a detectable HIV VL were independently associated with both types of disability. In addition, educational level was also independently associated with ADL disability. Age, educational level, low CD4(+) cell count, and detectable HIV VL were independently associated with disability. Whether effective and timely antiretroviral therapy will reduce the risk of disability in HIV-infected elderly patients needs to be evaluated. PMID:26559405

    Full Text Available Abstract Objectives HIV-infected patients are at increased risk of developing mental health symptoms, which negatively influence the treatment of the HIV-infection. Mental health problems in HIV-infected patients may affect public health. Psychopathology, including depression and substance abuse, can increase hazardous sexual behaviour and, with it, the chance of spreading HIV. Therefore, it is important to develop an optimal treatment plan for HIV-infected patients with mental health problems. The majority of HIV-infected patients in the Netherlands (almost 60% are homosexual men. The main objectives of this study were to describe the clinical and demographic characteristics of patients with HIV who seek treatment for their mental health symptoms in the Netherlands. Secondly, we tested whether HIV infected and non-infected homosexual patients with a lifetime depressive disorder differed on several mental health symptoms. Methods We compared a cohort of 196 patients who visited the outpatient clinic for HIV and Mental Health with HIV-infected patients in the general population in Amsterdam (ATHENA-study and with non-HIV infected mental health patients (NESDA-study. DSM-IV diagnoses were determined, and several self-report questionnaires were used to assess mental health symptoms. Results Depressive disorders were the most commonly occurring diagnoses in the cohort and frequent drug use was common. HIV-infected homosexual men with a depressive disorder showed no difference in depressive symptoms or sleep disturbance, compared with non-infected depressive men. However, HIV-positive patients did express more symptoms like fear, anger and guilt. Although they showed significantly more suicidal ideation, suicide attempts were not more prevalent among HIV-infected patients. Finally, the HIV-infected depressive patients displayed a considerably higher level of drug use than the HIV-negative group. Conclusion Habitual drug use is a risk factor for

    Care of patients with HIV infection starts with diagnosis as soon as possible, preferably at or near the time of acute infection. Opportunistic infections, malignancies, and other conditions develop progressively over time, particularly in untreated patients. The AIDS-defining opportunistic infections most common in the United States include Pneumocystis jirovecii pneumonia, Candida esophagitis, toxoplasmic encephalitis, tuberculosis, disseminated Mycobacterium avium complex, cryptococcal meningitis, and cytomegalovirus retinitis. Specific prophylaxis regimens exist for several opportunistic infections, and effective antiretroviral therapy reduces the risk of most others. Other AIDS-defining conditions include wasting syndrome and HIV encephalopathy. AIDS-defining malignancies include Kaposi sarcoma, systemic non-Hodgkin lymphoma, primary central nervous system lymphoma, and invasive cervical cancer. Although not an AIDS-defining condition, anal cancer is common in patients with HIV infection. Other HIV-related conditions include thrombocytopenia, recurrent bacterial respiratory infections, HIV-associated nephropathy, and HIV-associated neurocognitive disorder. PMID:27092563

    A 36-year-old HIV-positive man presented with symptoms of redness, blurred vision and foreign body sensation in his right eye for 3 months. The slit lamp examination revealed deep stromal infiltration with a feathery margin in an otherwise minimal anterior chamber reaction. A corneal scraping was negative. Confocal microscopy demonstrated an abnormal large hyper-reflective oval shape in the corneal stroma. Corneal infiltration did not show improvement after topical, intrastromal and intracameral antifungal treatment. Therapeutic penetrating keratoplasty was performed to eradicate the infection. Corneal button culture and histopathological results confirmed the diagnosis of Penicillium marneffei keratitis. No recurrent infection occurred after corneal transplantation. This appears to be the first report of P. marneffei keratitis in an HIV-infected patient. Although it is an uncommon condition, it should be one of the differential diagnoses in an HIV-infected patient presenting with keratitis. PMID:27535731

    Stress has significant adverse impacts on health outcomes of HIV-infected patients. Our study explored coping with stress strategies by HIV-infected Iranian patients. A qualitative content analysis study was conducted at the Consultation Clinic of HIV at the Imam Khomeini Hospital in Tehran, Iran in 2012. Twenty-six semi-structured in-depth interviews were done. Participants were asked about coping strategies for stress. After the first interview, continuous analysis of data was started and continued up to data saturation. Results showed that participants used two categories of strategies (emotion-based coping and problem-based coping) to cope with stress. Emotion-based coping had two sub-themes: adaptive and maladaptive. The problem-based coping category had three sub-themes: participation in education sessions, adherence to medication, and efforts to maintain a healthy lifestyle. Explanations of different strategies available to HIV-infected patients to cope with stress may help develop tailored interventions to improve the psychological conditions of people living with HIV.

    Participants were recruited from a sexually transmitted disease (STD) clinic in Florida and were assessed regarding the knowledge and awareness of non-AIDS conditions associated with HIV infection. Questionnaires were administered before and after a brief information session on non-AIDS conditions associated with HIV infection. Participants included men (n = 46) and women (n = 51). Prior to the information session, at baseline, only 34% of the participants were worried about HIV infection. Most participants (82%) agreed that HIV could be treated with antiretroviral therapy (ART), while only 38% were aware that HIV-associated conditions cannot be easily treated with ART. After the information session, almost all participants reported they were concerned regarding the risk of HIV infection. High-risk patients may have limited knowledge about the consequences of HIV infection beyond the traditional AIDS-associated conditions. Increased awareness of these less known consequences of HIV infection may decrease the potential for complacency regarding acquiring HIV infection. PMID:25331221

    2007-07-01

    Full Text Available Introduction & Objective: The risk of developing chronic hepatitis B virus (HBV is 5% in general population but can reach up to 20% in HIV patients. The response rate to HBV vaccine in HIV infected patients is 23.8-56 percent. The aim of this study was to evaluate response of HIV-infected patients to 20 µg dose of recombinant HBV vaccine. Materials & Methods: In this quasi experimental study, 51 subjects, sampled through census, were HIV patients who had HBsAg negative test in HIV/AIDS counseling and care center. Patients were vaccinated with 20 µg of recombinant HBV vaccine, IM at intervals of 0, 1 and 6 months. Response to the vaccine was checked 2 months after the last injection. Data were analyzed with SPSS software, using descriptive statistics and nonparametric tests. Results: The mean age of the patients was 33.68±8.37 years. Two patients were female (3.9% and 49 patients were male (96.1%. Mean of hepatitis B antibody level was 47.55±71.58 mIU/ml. The levels of antibody in different patients were as follow: 31 patients (60.8% 10 mIU/ml. There was no significant correlation between antibody levels and CD4+ cell count (correlation coefficient = -0.191. Conclusion: Response to hepatitis B vaccination is low in HIV infected patients. Conventional dose of HBV vaccine is not enough to get protective immunity. Therefore, two-fold dose of vaccine dose, repeat of conventional dose or increasing of interval administration of hepatitis B vaccine should be considered in future studies.

    Drug addicts have, in general, a less complicated course of HIV infection than homosexual HIV patients. They show fewer opportunistic infections and tumors. But this advantage is lost by unnecessary complications due to their psychic disorders. Their non-compliance and concealment of signs of disease lead to worse outcomes of infections, which could be well-treated or prevented. PMID:8300042

    Viral lesions of the mouth in patients with HIV infection are common and these diseases any be a marker for HIV and disease progression. We review the spectrum of oral viral manifestations and discuss treatment modalities. The most common Epstein-Barr virus (EBV)-induced disorder in HIV-infected patients is oral hairy leukoplakia. EBV-related oral B-cell and T-cell lymphoma in AIDS patients has been described repeatedly. Herpes virus type 1 and rarely type 2 may lead to painful and resistant oral ulcers, and systemic treatment with acyclovir, valaciclovir or famciclovir is indicated. In acyclovir-resistant cases foscarnet is the treatment of choice. In recent years it has been documented that Kaposi's sarcoma, which often affects oral mucosa, is probably induced by herpesvirus type 8. Cytomegalovirus was found in 53% of cases with herpesviridae-induced mucosal ulcers as the only ulcerogenic viral agent in AIDS patients. In severe cytomegalovirus infection treatment with ganciclovir is helpful. Viral warts induced by different HPV may occur in the mouth. Several physical treatment modalities are possible in the oral mucosa. In AIDS patients mollusca contagiosa may occur as large and atypical lesions in the face and lips and rarely in the oral cavity. Cryotherapy is a bloodless treatment in such patients. PMID:9031782

    Full Text Available To determine the prevalence of cryptosporidiosis among HIV infected and HIV non-infected patients with diarrhea in Edo State, Nigeria, as well as the effect of CD4+ lymphocyte count on the prevalence of cryptosporidial infection among the HIV patients. Stool samples were collected from 300 patients consisting of 200 HIV-infected and 100 HIV non-infected patients with diarrhea. Blood samples were collected from the HIV-infected patients. The stool samples were processed to detect Cryptosporidium species using a modified Ziehl-Neelsen stain, as well as other intestinal parasites using saline and iodine preparations. The blood samples were used to determine CD4+ lymphocyte count. The prevalence of intestinal parasites was higher in HIV-infected patients compared with their HIV non-infected counterparts (39% vs 24% respectively, p=0.0097. Cryptosporidiosis was diagnosed only among HIV-infected patients and was the only parasite whose prevalence was significantly different between HIV-infected and HIV non-infected patients. CD4+ lymphocyte count of <200 cells/µL among HIV-infected was a risk factor for acquiring cryptosporidial infection (OR=18.776, 95% CI=6.299, 55.964. A cryptosporidial infection prevalence of 18% among HIV-infected patients was observed and CD4+ count of <200 cells/µL was a risk factor for acquiring the disease. Routine examination of diarrhogenic stools of HIVinfected patients for cryptosporidiosis is advocated.

    Full Text Available Antiretroviral therapy in human immunodeficiency virus (HIV patients has prolonged survival and reduced the frequency of opportunistic infections (OI. However, following starting of antiretroviral therapy (ART, some patients experience a paradoxical worsening of clinical condition termed as immune reconstitution inflammatory syndrome (IRIS an entity, characterized by an excessive inflammatory response to a preexisting antigen or pathogen. Cryptococcus neoformans is one of the important pathogens that can cause an IRIS, in patients with low CD 4 cell counts in HIV patients. It is important to consider the possibility of cryptococcal infection in patients with advanced HIV infection, look for cryptococcal antigen in serum and cerebrospinal fluid along with blood culture. Blood cultures should be kept for further incubation for slow growing organisms by as demonstrated in the present case. We herewith report a case of IRIS due to cryptococcal meningitis in a patient with HIV1 infection with very low CD4 counts.

    2007-02-01

    Full Text Available Avascular necrosis (AVN of the femoral head is an emerging complication in HIV infected patients. It has been suggested that the increased incidence of AVN in this population may be caused by an increased prevalence of predisposing factors for osteonecrosis, including protease inhibitors, hyperlipidemia, corticosteroid use, alcohol and intravenous drug abuse. The aim of this study was to assess the risk factors for avascular necrosis developing in the femoral head of HIV infected individuals. This study consisted of meta-analysis of the secondary data extracted from current literature. The selected articles allowed two study groups to be drawn up for comparison. Group 1 comprised 324 individuals infected by the HIV virus, who did not present femoral head AVN. Group 2 comprised 32 HIV positive patients, who presented femoral head AVN. The parameters used for analysis were as follows: age, gender, sexual preference, use of intravenous drugs, time of diagnosis, CD4+ cell count, use of antiretroviral agents and duration, serum cholesterol and serum triglycerides. The present study found a statistically significant association between hypertriglyceridemia, hypercholesterolemia, sexual preference and intravenous drug abuse. The authors concluded that femoral head osteonecrosis is associated with hyperlipidemia (hypercholesterolemia and hypertriglyceridemia and intravenous drug abuse. This study supports the hypothesis that protease inhibitors play a role in the development of osteonecrosis through a tendency to cause hyperlipidemia.

    Objectives In HIV-uninfected populations, obstructive sleep apnea (OSA) is commonly associated with cardiovascular disease, metabolic syndrome, and cognitive impairment. These comorbidities are common in HIV-infected patients, but there are scarce data regarding OSA in HIV-infected patients. Therefore, we examined the prevalence and correlates of OSA in a cohort of HIV-infected and uninfected patients. Design Observational cohort study. Methods Electronic medical record and self-report data were examined in patients enrolled in the Veterans Aging Cohort Study (VACS) between 2002-2008 and followed through 2010. The primary outcome was OSA diagnosis, determined using ICD-9 codes, in HIV-infected compared with uninfected. We used regression analyses to determine the association between OSA diagnosis, symptoms and comorbidities in adjusted models. Results Of 3,683 HIV-infected and 3,641 uninfected patients, 143 (3.9%) and 453 (12.4%) had a diagnosis of OSA (p<0.0001), respectively. HIV-infected patients were more likely to report symptoms associated with sleep and OSA such as tiredness and fatigue. Compared with uninfected patients with OSA, HIV-infected patients with OSA were younger, had lower BMIs, and were less likely to have hypertension. In models adjusting for these traditional OSA risk factors, HIV infection was associated with markedly reduced odds of OSA diagnosis (odds ratio=0.48; 95% confidence interval 0.39—0.60). Conclusions HIV-infected patients are less likely to receive a diagnosis of OSA. Future studies are needed to determine whether the lower prevalence of OSA diagnoses in HIV-infected patients is due to decreased screening and detection or due to a truly decreased likelihood of OSA in the setting of HIV.

    Full Text Available Disseminated Mycobacterium avium complex (MAC infection is an important AIDS-defining opportunistic infection. The introduction of antimicrobial prophylaxis and antiretroviral therapy (ART markedly reduced the incidence of disseminated MAC infection and improved the survival of affected individuals. However, it seems that patients with new or recurrent MAC infection are still encountered in clinical practice. Our images captured the characteristic endoscopic findings of MAC duodenitis. The gastrointestinal (GI tract appears to be a common port of entry for MAC infection in patients with AIDS. Early recognition of GI MAC infection by endoscopy in HIV-infected patients and initiation of anti-MAC therapy and ART may reduce morbidity and mortality.

    There are numerous case reports on psychoses in AIDS patients and, although more seldom, also in HIV-positive patients in early stages of infection; however, systematic investigations on the frequency, e.g., relevant for the indication of an HIV test in psychiatric patients, are missing. For this study, 1046 HIV-positive patients were examined regarding psychoses. A total of 301 patients (28.8%) were HIV-positive but asymptomatic, and 380 patients (36.2%) had the lymphadenopathy syndrome. One hundred thirty-two patients (12.6%) suffered from an AIDS-related complex and 233 patients (22.3%) from AIDS. Of these 1046 patients, only 9 (0.9%) suffered from psychoses. One patient with a paranoid-hallucinatory syndrome was asymptomatic; one in the lymphadenopathy syndrome was manic. The other 7 patients were all in late stages of the infection. A causal relationship between HIV infection and psychosis and probable in only 3 patients. These data do not indicate a markedly elevated prevalence of psychosis in HIV-positive or AIDS patients.

    Full Text Available Objective: HIV can affect CNS in early stages of disease and determine neurological impairment. HBV DNA was found in CSF of HIV co-infected patients, but little is known about the neurotropic character of this virus. Here we assessed the degree of association between HBV infection and neurological impairment in a large cohort of long-term survivors, HIV-infected patients that experienced multiple therapeutic schemes over time. Methods: A total of 462 HIV-1-infected patients were retrospectively followed up for 10 years for HBV infection and neurological impairment. The patients were tested for immune (flow cytometry and virological parameters of HIV infection (Roche Amplicor, version 1.5/ COBAS AmpliPrep/COBAS TaqMan HIV-1 test and for HBV infection markers (HBsAg, anti HBc: Murex Biotech ELISA tests. Many of these patients have experienced between one and six regimens such as: 2 NRTIs, 3 NRTIs, 2 NRTIs+1 NNRTI, 1 NRTI+1 NNRTI+1 PI, 2 NRTIs+2 PIs. Results: After 10 years 29.87% of the patients presented neurological impairment. Out of them 56.52% were HBV-infected. The prevalence of HIV encephalopathy (HE in our studied cohort was 22.7% and 50.4% of these patients were HBV-infected. The median HIV diagnosis age was 7 and the median age of HE diagnosis was 10. In order to establish a possible correlation between HBV infection and HE we first reviewed and excluded the main risk factors associated with HE at the moment of diagnosis: low weight, anemia, constitutional symptoms, low CD4+count, high plasma HIV-RNA load. No patient was infected with HCV. The groups of patients that presented HE and HBsAg and HE without HBsAg were balanced regarding sex, number of deceased patients, number of class C3 patients, but the patients in first group presented lower CD4 values at HE diagnosis vs patients from second group 2: 44.5 vs 95 cells/µL, p=0.3; lower nadir CD4 count: 38 vs 51 cell/µL, p=0.1; and slightly higher HIV viral load: 5.2 vs 5 log10 copies

    Diarrhea is a common clinical manifestation of HIV infection regardless of whether the patients have AIDS. HIV and malnutrition tend to occur in the same populations, the underprivileged and resource-poor. Malnutrition increases severity and mortality of infection. Occurrence of chronic diarrhea in HIV-infected patients, gut status and pathogenic agents, nutritional status and the crucial role of nutrition are reviewed. Bovine colostrum-based food can be useful for managing chronic diarrhea in HIV-infected patients, enhancing both nutritional and immunological status. PMID:22096401

    The purpose of this study was to identify fecal bacterial microbiome changes in patients with chronic human immunodeficiency virus (HIV) infection in China. Bacterial 16S rRNA genes were amplified, sequenced (454 pyrosequencing), and clustered into operational taxonomic units using the QIIME software. Relative abundance at the phylum and genus levels were calculated. Alpha diversity was determined by Chao 1 and observed-species indices, and beta diversity was determined by double principal component analysis using the estimated phylogeny-based unweighted Unifrac distance matrices. Fecal samples of the patients with chronic HIV-infection tended to be enriched with bacteria of the phyla Firmicutes (47.20%±0.43 relative abundance) and Proteobacteria (37.21%±0.36) compared with those of the non-HIV infected controls (17.95%±0.06 and 3.81%±0.02, respectively). Members of the genus Bilophila were exclusively detected in samples of the non-HIV infected controls. Bacteroides and arabacteroides were more abundant in the chronic HIV-infected patients. Our study indicated that chronic HIV-infected patients in China have a fecal bacterial microbiome composition that is largely different from that found in non-HIV infected controls, and further study is needed to evaluate whether microbiome changes play a role in disease complications in the distal gut, including opportunistic infections.

We present data from a series of HIV-infected ARV-experienced patients receiving etravirine-containing regimens, in whom etravirine concentrations and viral loads were determined in blood plasma and seminal plasma. The objective was to determine etravirine concentrations and HIV-1 viral load (VL in blood plasma (BP and seminal plasma (SP of HIV-infected patients. Methods: Ten HIV-1 adult antiretroviral-experienced patients receiving an etravirine-containing regimen for at least 1 month were enrolled. Semen and blood samples were both collected around 12–24 h after the last etravirine dose, depending on once-daily or twice-daily dosing, respectively. HPLC/MS/MS was used to determine etravirine concentrations, and HIV-1 VL was determined by real-time PCR (limit of detection, VL 40 copies/mL. Results: Ten blood and twenty semen samples were collected. Median (range CD4 count was 502 cells/mm3 (252–817 and median (range BP VL was<40 copies/mL (40–362. Median (range time on etravirine was 52 weeks (12–124. Median (range BP etravirine concentration was 452.5 ng/mL (258–751. Median (range SP etravirine concentration was 62.9 ng/mL (31.2–166, and values were above the protein-free IC50 range (0.39–2.4 ng/mL in all cases. Median (range etravirine SP:BP ratio was 0.16 (0.07–0.26. SP VL was<40 copies/mL in all patients, whereas BP VL was detectable in one patient with poor adherence to treatment. Conclusions: Total etravirine concentrations in male genital secretion are modest, reaching only 16% of the BP concentration, but nevertheless, more than 10 times above the wild type IC50 range.

    Compared with high infection areas of the world, the total HIV infection rate in China is relatively low. Nonetheless,because of China's vast territory and large population, the potential infection risk must be taken seriously. In the next few years, needle sharing among injection drug users will remain the most common route of transmission for the HIV/AIDS epidemic in China. Unprotected sex is gradually becoming a major route of transmission. China began to implement HAART in 1999 according to international standards. Prior to 2003, there were only about 150 HIV/AIDS patients were treated with HAART in some clinical trials and about 100 HIV/AIDS patients were treated by private sources.Results of those treatments are the scientific basis for development of the therapeutic strategies in China. In March of 2003, the Chinese government initiated China CARES program. In November of 2003, the Chinese Ministry of Health announced a national policy of free ARV treatment to all HIV+ Chinese citizens who were in poverty and required ARV therapy. There are total of 19,456 HIV/AIDS patients received free ARV drugs to date in 159 regions and 441 towns.Current challenges are how to follow-up and evaluate those patients in the clinical settings. The longer the therapy is postponed, the more side effects and the higher probability of drug resistance are going to occur. It remains unclear,therefore, when HAART regimen should be started in the HIV/AIDS population in China.

    Full Text Available Abstract Background Surgical site infection (SSI are the third most frequently reported nosocomial infection, and the most common on surgical wards. HIV-infected patients may increase the possibility of developing SSI after surgery. There are few reported date on incidence and the preventive measures of SSI in HIV-infected patients. This study was to determine the incidence and the associated risk factors for SSI in HIV-infected patients. And we also explored the preventive measures. Methods A retrospective study of SSI was conducted in 242 HIV-infected patients including 17 patients who combined with hemophilia from October 2008 to September 2011 in Shanghai Public Health Clinical Center. SSI were classified according to Centers for Disease Control and Prevention (CDC criteria and identified by bedside surveillance and post-discharge follow-up. Data were analyzed using SPSS 16.0 statistical software (SPSS Inc., Chicago, IL. Results The SSI incidence rate was 47.5% (115 of 242; 38.4% incisional SSIs, 5.4% deep incisional SSIs and 3.7% organ/space SSIs. The SSI incidence rate was 37.9% in HIV-infected patients undergoing abdominal operation. Patients undergoing abdominal surgery with lower preoperative CD4 counts were more likely to develop SSIs. The incidence increased from 2.6% in clean wounds to 100% in dirty wounds. In the HIV-infected patients combined with hemophilia, the mean preoperative albumin and postoperative hemoglobin were found significantly lower than those in no-SSIs group (P Conclusions SSI is frequent in HIV-infected patients. And suitable perioperative management may decrease the SSIs incidence rate of HIV-infected patients.

    Full Text Available Background: Itchy folliculitis are pruritic, folliculo-papular lesions seen in human immunodeficiency virus (HIV-infected patients. Previous studies have shown that it was impossible to clinically differentiate between eosinophilic folliculitis (EF and infective folliculitis (IF. Also, attempts to suppress the intense itch of EF were ineffective. Aims: The present study is aimed at correlating clinical, histopathological and immunological features of itchy folliculitis in HIV patients along with their treatment. Methods: The present prospective study lasted for 36 months (September, 2005 to August, 2008 after informed consent, data on skin disorders, HIV status and CD4 count were obtained by physical examination, histopathological examination and laboratory methods. Results: Of 51 HIV-positive patients with itchy folliculitis, the predominant lesion was EF in 23 (45.1% followed by bacterial folliculitis in 21 (41.2%, Pityrosporum folliculitis in five (9.8% and Demodex folliculitis in two (3.9% patients. The diagnosis was based on characteristic histopathological features and was also associated with microbiology confirmation wherever required. EF was associated with a lower mean CD4 count (180.58 ± 48.07 cells/mm 3 , P-value < 0.05, higher mean CD8 count (1675.42 ± 407.62 cells/mm3 and CD8/CD4 ratio of 9.27:1. There was significant reduction in lesions following specific treatment for the specific lesion identified. Conclusion: Clinically, it is impossible to differentiate itchy folliculitis and therefore it requires histopathological confirmation. Appropriate antimicrobial treatment for IF can be rapidly beneficial. The highly active antiretroviral therapy along with Isotretinoin therapy has shown marked reduction in the lesions of EF. Familiarity with these lesions may help in improving the quality of lives of the patients.

  16. Antibodies from the sera of HIV-infected patients efficiently hydrolyze all human histones.

    2016-08-01

    Histones and their post-translational modifications have key roles in chromatin remodeling and gene transcription. Besides intranuclear functions, histones act as damage-associated molecular pattern molecules when they are released into the extracellular space. Administration of exogenous histones to animals leads to systemic inflammatory and toxic responses through activating Toll-like receptors and inflammasome pathways. Here, using ELISA it was shown that sera of HIV-infected patients and healthy donors contain autoantibodies against histones. Autoantibodies with enzymic activities (abzymes) are a distinctive feature of autoimmune diseases. It was interesting whether antibodies from sera of HIV-infected patients can hydrolyze human histones. Electrophoretically and immunologically homogeneous IgGs were isolated from sera of HIV-infected patients by chromatography on several affinity sorbents. We present first evidence showing that 100% of IgGs purified from the sera of 32 HIV-infected patients efficiently hydrolyze from one to five human histones. Several rigid criteria have been applied to show that the histone-hydrolyzing activity is an intrinsic property of IgGs of HIV-infected patients. The relative efficiency of hydrolysis of histones (H1, H2a, H2b, H3, and H4) significantly varied for IgGs of different patients. IgGs from the sera of 40% of healthy donors also hydrolyze histones but with an average efficiency approximately 16-fold lower than that of HIV-infected patients. Similar to proteolytic abzymes from the sera of patients with several autoimmune diseases, histone-hydrolyzing IgGs from HIV-infected patients were inhibited by specific inhibitors of serine and of metal-dependent proteases, but an unexpected significant inhibition of the activity by specific inhibitor of thiol-like proteases was also observed. Because IgGs can efficiently hydrolyze histones, a negative role of abzymes in development of acquired immune deficiency syndrome cannot be

    2016-02-01

    The care of the HIV-infected patient in the emergency department has changed since the development of highly active antiretroviral therapy. This therapy has resulted in longer life expectancies and increased quality of life for HIV-infected patients, and in cases of treatment compliance and success, virtual elimination of AIDS-associated opportunistic infections. As a result, the emergency clinician is now more often confronted with adverse events related to medication and the diseases associated with aging and chronic disease. This issue focuses on the differences in evaluation of HIV patients on long-term therapy and patients with medication noncompliance and low CD4 counts, as well as recognition of life-threatening and rare opportunistic infections. Disease processes related to the effect of longstanding HIV infection, even with good control, on many organ systems are addressed. PMID:26760316

  5. Diagnostic results of adbominal computed tomography in HIV-infected patients

    International Nuclear Information System (INIS)

    The exact frequency of pathologic findings in abdominal computed tomograms of HIV-infected patients is not yet known. To analyse such findings, CT scans of 339 HIV-infected patients were reviewed. While over four fifths of patients displayed abnormal findings; hepatosplenomegaly, lymphadenopathy, pathologically enlarged lymph nodes, and bowel wall thickening were the most common signs of disease. Only for enlarged lymph nodes could a dependency on clinical stage of the infection be demonstrated. As a conclusion, abdominal computed tomography reveals pathologic findings in the vast majority of HIV-infected patients, almost independent of clinical stage. Specifically, CT provides well documented lymph node staging. There are practically no age- or sex-dependent disease patterns in abdominal CT scans. (orig.)

    Objectives: Enteric parasites are a major cause of diarrhoea in HIV/AIDS patients with low CD4 counts. Parasitic infections in HIV-infected individuals can reduce their quality of life and life span, especially those who are severely immunosuppressed with a CD4 T-lymphocyte count 0.05). Conclusions: Low CD4 counts in HIV-infected patients can lead to enteric infections. This information strengthens the importance of monitoring CD4 counts and intestinal parasites. Routine CD4 testing will greatly improve the prognosis of HIV positive patients. (author)

    Full Text Available Background:HIV infected patients, especially those treated with antiretroviral (ARV drugs, show an increased risk and incidence of cardiovascular disease.Objectives:The aim of this study was to evaluate the progression of subclinical atherosclerosis in the carotid arteries, expressed as the value of carotid intima-media thickness (cIMT and the amount of atherosclerotic plaques, and to analyze the correlation between cIMT and risk factors for cardiovascular diseases in a cohort of HIV infected patients.Methods:The analysis included 72 HIV infected patients, mean age 39.4 years, and 27 healthy HIV negative individuals, matched for age and sex. The data collected included evaluation of the infection, ARV treatment, past cardiovascular events, assessment of traditional and nontraditional risk factors for cardiovascular diseases, cIMT measurements and amount of atherosclerotic plaques in the carotid arteries.Results:HIV infected patients show more advanced subclinical atherosclerosis in the carotid arteries (cIMT and plaques incidence. The cardiovascular risk profile of the HIV infected patients is significantly different from HIV negative people. Among the HIV positive group lower body mass index (BMI and higher waist/hip ratio (WHR are observed. The concentration of all cholesterol fractions is lower, whereas the concentration of triglycerides is higher. Cigarette smoking is more common among HIV-infected individuals. A strong statistical correlation between cIMT and age, hypertension, non-high-density lipoprotein (non-HDL cholesterol and ARV time were found. Total and LDL cholesterol, and lifetime smoking exposure also affect the cIMT. The relationship between cIMT and current HIV RNA may indicate the impact of the current infection status on the cIMT dynamics in this subpopulation.

    Data regarding syphilis screening in resource-limited settings is limited. We aimed to determine the prevalence and associated factors of positive syphilis serology in HIV-infected adult patients in an outpatient setting in Thailand. A cross sectional study was conducted among 178 HIV-infected patients. Ninety-eight patients (55%) were male; then median (interquartile range; IQR) age was 43 (36-49) years. The majority of the patients (84.3%) had a heterosexual risk. Three patients (1.7%) had a positive rapid plasma reagin (RPR) test (range, 1:2 to 1:16), 9 (5%) patients had a positive Treponema pallidum particle agglutination (TPPA) test, and 3 patients (1.7%) had positive results on both tests. On multivariate logistic regression analysis, a pruritic papular eruption [odds ratio (OR) 5.37; 95% confidence interval (CI): 1.09-26.38; p = 0.038], current CD4 cell count (OR 1.22, per 50 cells/mm3; 95% CI: 1.01-1.46; p = 0.035), and using abacavir in the current regimen (OR 59.19; 95% CI: 2.15-1,628.68; p = 0.016) were associated with positive syphilis serology. In conclusion, the prevalence of positive syphilis serology among Thai HIV-infected patients was low. Routine screening for syphilis in HIV-infected patients who are asymptomatic may need to be re-considered at the national level in this resource-limited setting. PMID:24968686

    Full Text Available Abstract Increases in aminotransferases levels are frequently encountered in HIV-positive patients and often remain unexplained. The role in this setting and natural history of hepatitis E in HIV-infected patients are unknown. The aim of the study was to assess HEV infection in HIV-infected patients attending a Parisian hospital, with a current or previous cryptogenic hepatitis.191 plasma samples collected from 108 HIV-infected patients with elevated aminotransferases levels were retrospectively tested for the presence of hepatitis E virus (HEV infection markers: anti-HEV IgM antibodies, anti-HEV IgG antibodies, anti-HEV IgG avidity index and plasma HEV RNA.One acute infection, documented by positive tests for anti-HEV IgM antibody, low anti-HEV IgG avidity index and plasma HEV RNA (genotype 3e, and three past infections were diagnosed, without any observed case of persistent infection. The acute hepatitis was benign and resolved spontaneously within two weeks. This infection was probably contracted locally. Acute HEV hepatitis can occur in HIV-infected patients but rarely explains cryptogenic hepatitis, at least in an urban HIV population, regardless geographic origin and CD4 counts.

    Full Text Available Abstract Background Even though it has been suggested that antiretroviral therapy has an impact on severe hypovitaminosis D (SHD in HIV infected patients, it could be speculated that the different levels of residual inflammation on HAART (Highly Active Anti Retroviral Therapy could contribute to SHD and aggravate bone catabolism in these patients. Methods A cross-sectional study was carried out in an unselected cohort of 263 HIV infected outpatients consulting during Spring 2010. Clinical examinations were performed and medical history, food habits, sun exposure and addictions were collected. Fasting blood samples were taken for immunological, virological, inflammation, endocrine and bone markers evaluations. Results Ninety-five (36% patients had SHD. In univariate analysis, a significant and positive association was found between SHD and IL6 (p = 0.001, hsCRP (p = 0.04, increased serum C-Telopeptides X (CTX (p = 0.005 and Parathyroid Hormon (PTH (p Conclusions SHD is frequent and correlates with inflammation in HIV infected patients. Since SHD is also associated with falls and increased bone catabolism, it may be of interest to take into account not only the type of antiretroviral therapy but also the residual inflammation on HAART in order to assess functional and bone risks. This finding also suggests that vitamin D supplementation may be beneficial in these HIV-infected patients.

    Full Text Available OBJECTIVE: In view of the practical need to use equations for the evaluation of energy expenditure in HIV-infected patients, the objective of the present study was to determine the concordance between the energy expenditure values obtained by indirect calorimetry as the gold standard and those obtained by predictive equations elaborated from data for the healthy population: Harris-Benedict, Schofield and Cunningham, and by equations elaborated from data for HIV-infected patients: Melchior (1991-1993. METHODS: The study was conducted at the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto on 32 HIV-infected men under treatment with highly active antiretroviral therapy. Resting energy expenditure was measured by indirect calorimetry and estimated on the basis of measurement of O2 consumption and CO2 production. RESULTS: Statistical analysis revealed weak concordance for the Harris-Benedict (0.38 and Cunningham (0.34 equations and satisfactory concordance for the Schofield equation (0.47. Only the two Melchior equations (1991 and 1993 showed strong concordance with the values obtained by indirect calorimetry (0.63 and 0.66, respectively and could be used in practice. CONCLUSION: The best equations seem to be population-specific, such as the Melchior equations elaborated for HIV-infected patients.

  1. FDG-PET imaging in HIV-infected subjects: relation with therapy and immunovirological variables

    International Nuclear Information System (INIS)

    To characterise tissue sites of immune activation and HIV replication we performed FDG-PET in ART-treated and ART-naive HIV-infected individuals. Specific aims were to establish whether HIV-infected patients can be differentiated on the basis of the detection of specific locations of viral replication, even in the presence of an apparently optimal immunovirological response to ART, and whether these FDG-PET findings can be related to immunovirological variables and AIDS history status. Patients were divided into five groups as follows: subgroup A1 (full responders, n=8): current ART treatment, CD4+ T lymphocytes >500/mL, viral load 50,000 copies/mL; group C (ART-naive, n=5): no current or previous ART treatment, increased viral load. PET images revealed different patterns of FDG uptake. All ART-treated patients with either suppressed (<50 copies/mL; Group A) or high viremia (group B) showed a normal pattern of FDG uptake. On the contrary, the ART-naive subjects with high viraemia (group C) displayed multiple foci of increased glucose metabolism in the lymph nodes. In the ART-naive subjects, FDG uptake, apparently related to viraemia level, was observed in the upper torso mainly in the axillary nodes bilaterally in patients with viraemia below 100,000 copies/mL; in those with viraemia higher than 100,000 copies/mL, FDG uptake was also observed in the inguinal lymph nodes. The emergence, in our study, of a correlation between the percentage of CD8+/CD38+/RO+ T cells (well established markers of progression to AIDS independently of CD4+ T lymphocytes) and positive FDG-PET in ART-naive patients is a novel finding that seems to confer prognostic value on FDG uptake. FDG uptake is strongly associated with response to ART independently of a previous AIDS diagnosis. Notably, no differences were observed between ART-treated subjects classed as immunological responders and those classed as non responders. Data herewith indicate that FDG uptake and immunological variables are

    Introduction: Spontaneous pneumothorax (SP) is a frequent complication in non-treated HIV-infected patients as a complication of opportunistic infections and tumours. Objective: To analyse the aetiology of SP in non-treated HIV patients. Patients and methods: Observational study of SP cases observed in a cohort of 9831 of non-treated HIV-infected patients attended in seven Spanish hospitals. Results: 105 patients (1.06%) developed SP. The aetiological cause was identified in 89 patients. The major causes identified were: bacterial pneumonia (36 subjects, 34.3%); Pneumocystis jiroveci pneumonia (PJP) (31 patients, 29.5%); and pulmonary tuberculosis (17 cases, 15.2%). The most common cause of SP in drugs users was bacterial pneumonia (40%), whereas PJP was more common (65%) in sexual transmitted HIV-patients. The most common cause of bilateral SP was PJP (62.5%) whereas unilateral SP was most commonly associated with bacterial pneumonia (40.2%). The most common cause of SP in patients with a CD4+ lymphocyte count >200 cells/ml and in patients without AIDS criteria was bacterial pneumonia. PJP was the more common cause in patients with a CD4+ lymphocyte count <200 cells/ml or with AIDS. Conclusion: The incidence of SP in non-treated HIV-infected patients was 1.06%. The aetiology was related to the patients risk practices and to their degree of immunosuppression. Bacterial pneumonia was the most common cause of SP.

    SETTING AIDS and tuberculosis center in Port-au-Prince, Haiti. OBJECTIVE To measure the effectiveness of tuberculosis retreatment with the standard regimen (2HRZES/1HRZE/5HRE) in HIV-infected adults. DESIGN Cohort study. RESULTS Of 1,318 HIV-infected patients with access to antiretroviral therapy following World Health Organization guidelines, 56 were diagnosed with recurrent pulmonary tuberculosis and retreated with the standard regimen. Ten patients (18%) died during retreatment, 3 patients (5%) defaulted, and 2 patients (4%) failed. Forty-one patients (73%) had a good retreatment outcome (cure, treatment completed). Of these, 8 patients (20%) died during follow-up, 5 patients (12%) were lost, and 5 patients (12%) had a second recurrence of tuberculosis. Only 26 (46%) of the 56 patients remained alive, in-care, and TB-free after a median of 36 months follow-up. CONCLUSION HIV-infected patients treated for recurrent tuberculosis with the standard retreatment regimen have a high mortality and poor long-term outcomes. PMID:22507948

    Full Text Available The human immunodeficiency virus (HIV epidemic in Turkey reveals a slow progression and at the end of November 2015, the total official number was reported to be 11,109 cases. Approximately 90% of HIV patients develop some type of skin disease. Especially patients with psoriasis and HIV infection often present with more severe and treatment-refractory cutaneous disease. Herein, we describe a case of a patient with previously known psoriasis worsened by HIV infection. A 37-year-old housewife was admitted to our clinic with previously known psoriasis worsened during the last two years with conversion to erythrodermic psoriasis which was not controlled even by PUVA, methotrexate and systemic cyclosporine. The patient had positive HIV antibody test. HIV RNA viral load was 120.000 copy/ml and CD4 count 88/ mm3 . She also had oral candidiasis and Pneumocystis jirovecii pneumonia. The patient received antiretroviral treatment including tenofovir/emtricitabine and lopinavir/ritonavir. Symptoms resolved gradually within one month with almost complete impovement of her erythrodermic psoriasis. . Four years later the patient was still on tenofovir/emtricitabine and lopinavir/ritonavir without concomitant spesific psoriasis treatment. Psoriasis manifestations can be severe in AIDS patients. Clinicians face diagnostic and therapeutic difficulties when psoriasis coexists with HIV infection. The HIV test should be considered in patients affected by severe erythrodermic psoriasis and resistant to conventional and biological treatments. [Dis Mol Med 2015; 3(4.000: 43-45

In this study we identified the yeast populations associated with oral lesions in HIV-infected patients in Southwest Uganda who were receiving treatment with nystatin and topical clotrimazole. Samples were taken from 605 patients and 316 (52%) of these yielded yeast growth following incubation on Sabouraud dextrose agar. Samples were subsequently re-plated on CHROMagar Candida medium to facilitate identification of the yeast species present. The majority (56%) of culture-positive samples yielded a mix of two or more species. Candida albicans was present in 87% (274\\/316) of patient samples and accounted for 87% (120\\/138) of single species samples. Candida glabrata, Candida tropicalis and Candida norvegensis were also found in cultures that yielded a single species. No Candida dubliniensis isolates were identified in this population.

    Periodic lateralized epileptiform discharges (PLEDs) are an electroencephalographic pattern recorded in the setting of a variety of brain abnormalities. It is best recognized for its association with acute viral encephalitis, stroke, tumor, or latestatus epilepticus. However, there are other conditions that have been recognized as the underlying pathology for PLEDs such as alcohol withdrawal, Creutzfeldt-Jacob disease, anoxic brain injury, and hemiplegic migraine. However, there are only rare case reports of PLEDs in patients with neurosyphilis. Here, we report 2 patients presenting with encephalopathy and seizures with PLEDs, ipsilateral or contralateral to their main brain magnetic resonance imaging abnormalities. Further workup revealed neurosyphilis in both patients, one in association with human immunodeficiency virus (HIV) infection. Given the increasing incidence of neurosyphilis with or without HIV infection, these cases suggest neurosyphilis as a consideration in the differential for patients presenting with PLEDs.

    The choroid plexus (CPx) may be an important site of viral dissemination since monocytes and dendritic cells in its stroma are infected with HIV in AIDS patients and since the ratio of CPx to brain infection is more than 2 : 1. In order to see if CPx infection also develops in asymptomatic (ASY) HIV-infected patients, we examined archival formalin-fixed brain and CPx from 14 AIDS and seven ASY cases, using routine histology, immunohistochemistry for HIV gp41, and DNA extraction and gene amplification for HIV DNA. Eight of 14 AIDS (57%) had HIV-positive cells in the CPx and four (29%) had HIV encephalitis. Two of seven ASY cases (29%) had HIV-positive cells in the CPx but none had HIV encephalitis. Extracted DNA from brain, CPx and systemic organs of five ASY cases was amplified by nested PCR with or without Southern blotting for HIV env gene. It was positive in systemic organs in five cases; in CPx in four cases; and in brain in one case. This study shows that the CPx is a site of HIV infection in ASY patients and that the frequency of CPx infection is higher than seen in brain in both AIDS and ASY cases. The results are consistent with the hypothesis that the CPx may be a site for hematogeneous spread and a reservoir for HIV infection during the period of clinical latency. PMID:10602407

    A Rizal Ganiem

    Full Text Available BACKGROUND: HIV-associated subacute meningitis is mostly caused by tuberculosis or cryptococcosis, but often no etiology can be established. In the absence of CT or MRI of the brain, toxoplasmosis is generally not considered as part of the differential diagnosis. METHODOLOGY/PRINCIPAL FINDINGS: We performed cerebrospinal fluid real time PCR and serological testing for Toxoplasma gondii in archived samples from a well-characterized cohort of 64 HIV-infected patients presenting with subacute meningitis in a referral hospital in Indonesia. Neuroradiology was only available for 6 patients. At time of presentation, patients mostly had newly diagnosed and advanced HIV infection (median CD4 count 22 cells/mL, with only 17.2% taking ART, and 9.4% PJP-prophylaxis. CSF PCR for T. Gondii was positive in 21 patients (32.8%. Circulating toxoplasma IgG was present in 77.2% of patients tested, including all in whom the PCR of CSF was positive for T. Gondii. Clinically, in the absence of neuroradiology, toxoplasmosis was difficult to distinguish from tuberculosis or cryptococcal meningitis, although CSF abnormalities were less pronounced. Mortality among patients with a positive CSF T. Gondii PCR was 81%, 2.16-fold higher (95% CI 1.04-4.47 compared to those with a negative PCR. CONCLUSIONS/SIGNIFICANCE: Toxoplasmosis should be considered in HIV-infected patients with clinically suspected subacute meningitis in settings where neuroradiology is not available.

    Full Text Available Abstract The occurrence of acute promyelocytic leukemia (APL in HIV-infected patients has been reported in only five cases. Due to a very small number of reported HIV/APL patients who have been treated with different therapies with the variable outcome, the prognosis of APL in the setting of the HIV-infection is unclear. Here, we report a case of an HIV-patient who developed APL and upon treatment entered a complete remission. A 25-years old male patient was diagnosed with HIV-infection in 1996, but remained untreated. In 2004, the patient was diagnosed with primary central nervous system lymphoma. We treated the patient with antiretroviral therapy and whole-brain irradiation, resulting in complete remission of the lymphoma. In 2006, prompted by a sudden neutropenia, we carried out a set of diagnostic procedures, revealing APL. Induction therapy consisted of standard treatment with all-trans-retinoic-acid (ATRA and idarubicin. Subsequent cytological and molecular analysis of bone marrow demonstrated complete hematological and molecular remission. Due to the poor general condition, consolidation treatment with ATRA was given in March and April 2007. The last follow-up 14 months later, showed sustained molecular APL remission. In conclusion, we demonstrated that a complete molecular APL remission in an HIV-patient was achieved by using reduced-intensity treatment.

    2007-01-01

    AIM: To screen for the co-infection of hepatitis B (HBV)and hepatitis C virus (HCV) in human immunodeficiency virus (HIV) infected patients insouthern India.METHODS: Five hundred consecutive HIV infected patients were screened for Hepatitis B Virus (HBsAg and HBV-DNA) and Hepatitis C virus (anti-HCV and HCV-RNA)using commercially available ELISA kits; HBsAg, HBeAg/anti-HBe (Biorad laboratories, USA) and anti-HCV (Murex Diagnostics, UK). The HBV-DNA PCR was performed to detect the surface antigen region (pre S-S). HCV-RNA was detected by RT-PCR for the detection of the constant 5' putative non-coding region of HCV.RESULTS: HBV co-infection was detected in 45/500 (9%)patients and HCV co-infection in 11/500 (2.2%) subjects.Among the 45 co-infected patients only 40 patients could be studied, where the detection rates of HBe was 55%(22/40), antiHBe was 45% (18/40) and HBV-DNA was 56% (23/40). Among 11 HCV co-infected subjects, 6(54.5%) were anti-HCV and HCV RNA positive, while 3(27.2%) were positive for anti-HCV alone and 2 (18%)were positive for HCV RNA alone.CONCLUSION: Since the principal routes for HIV transmission are similar to that followed by the hepatotropic viruses, as a consequence, infections with HBV and HCV are expected in HIV infected patients.Therefore, it would be advisable to screen for these viruses in all the HIV infected individuals and their sexual partners at the earliest.

    Full Text Available Purpose: HIV-infected patients treated for syphilis may be at increased risk for serological failure and serofast state. Our aim was to analyse serological response to treatment in HIV-infected patients diagnosed with syphilis, and factors associated with serological cure and serofast state. Methods: Open-label, no controlled study of a series of HIV-patients diagnosed with syphilis during 2004–2011. Patients were categorized by rapid plasma reagin titer (RPR into success (4-fold decrease in RPR by 12 or 24 months after treatment of early or late syphilis, serofast (success with persistently stable reactive RPR, and failure/re-infection (failure to decrease 4-fold in RPR by 12 or 24 months after treatment or sustained 4-fold increase in RPR after treatment response. Results: 141 HIV-patients were diagnosed with syphilis during the study period (104 early syphilis, 36 late or indeterminate latent syphilis. The mean age was 36.3 years, 98.5% were male, and 87.2% homosexual men. In 46 (32.6% cases, HIV and syphilis infection diagnosis were coincident (mean CD4 457/mm3 and HIV-VL 4.72 log10. Among patients with prior known HIV infection, 65 were on antiretroviral therapy (ART at syphilis diagnosis (mean CD4 469/mm3, 76.9% undetectable HIV-VL. 116 patients satisfied criteria for serological response analysis (89 early, 24 late/indeterminate. At 12 months of early syphilis treatment (89.2% penicillin there were 16 (18% failures, and at 24 months of late/indeterminate syphilis (91.7% penicillin there were 5 (18.5% failures. Overall, 36 (31.0% patients presented serofast state. Treatment failure was related with lower CD4 count (295 vs 510/mL; p=0.045 only in patients with coincident diagnosis. Serofast state was related with older age (41 vs 36 years; p=0.024, and lower CD4 count (391 vs 513/mm3; p=0.026.

    The examination was carried out in the Moscow clinical infectious hospital No 2 concerning 102 patients with verified diagnosis "AIDS-infection" and seropositive according results of detection of anti-HIV-antibodies in blood serum. The study was organized to analyze rate ofcolonization of gums with virulent anaerobic bacteria in HIV-infected (polymerase chain reaction) and antibodies to HIV in gingival fluid (enzyme-linked immunosorbent assay). It is established that in HIV-infected patients, in scrape from gingival sulcus dominate anaerobic bacteria P. gigngivalis and A. ctinomycetemcomitans and in case of periodontitis--P. gingivalis and T. forsythia. The received data permits recommending the test-system "Multident-5" for polymerase chain reaction diagnostic. The reagents kit "Calypte®HIV-1/2"--for enzyme-linked immunosorbent assay gingival fluid. The results of polymerase chain reaction and enzyme-linked immunosorbent assay have no impact of concomitant stomatological (periodontitis, gingivitis) and somatic pathology. PMID:27183732

    Cryptococcal meningitis (CM) is a life-threatening mycosis primarily occurring in HIV-infected individuals. Recently, non-HIV-infected hosts were increasingly reported to form a considerable proportion. However, the majority of the reported studies on the diagnosis of CM patients were performed on HIV-infected patients. For evaluation of various diagnostic approaches for CM in non-HIV-infected patients, a range of conventional and molecular assays used for diagnosis of CM were verified on 85 clinical CSFs from non-HIV-infected CM patients, including India ink staining, culture, a newly developed loop-mediated isothermal amplification (LAMP), the lateral flow assay (LFA) of cryptococcal antigen detection and a qPCR assay. The LFA had the highest positive detection rate (97.6%; 95% CI, 91.8-99.7%) in non-HIV-infected CM patients, followed by the LAMP (87.1%; 95% CI, 78.0-93.4%), the qPCR (80.0%; 95% CI, 69.9-87.9%), India ink staining (70.6%; 95% CI, 59.7-80.0%) and culture (35.3%; 95% CI, 25.2-46.4%). All culture positive specimens were correctly identified by the LFA. PMID:27061343

    2006-05-15

    Life expectancy of HIV-infected patients has improved considerably with HAART. However long term use of HAART is linked with lipodystrophy syndrom (subcutaneous lipoatrophy and central fat accumulation) associated with dyslipemia (hypoHDL, hyperLDL and hypertriglyceridemia) and insulin resistance. It is also linked with mitochondrial toxicity clinically expressed by chronic fatigue syndrom and premature aging. The induced metabolic syndrom has cardiovascular consequences and myocardial infarction is the cause of 7% of the HIV-infected deaths in 2000. Assessment of these complications should be done at least every year. Treatment options concern antiretroviral therapy with the search for the least toxic drug (but with equal antiviral efficacy), symptomatic treatment (statin, fibrates, thiazolidinediones, metformin) and lifestyle modifications (first of all, stopping cigarette smoking!)

    Full Text Available Según la literatura, la osteonecrosis tiene una mayor incidencia en los pacientes infectados con HIV que en la población general. Ello sería resultado de la confluencia de factores de riesgo clásicos y de otros propios de esta población o más prevalentes en ella, como el tratamiento con inhibidores de proteasa, la dislipemia producto de su consumo, la presencia de anticuerpos anticardiolipina séricos, la hipercoagulabilidad, la restauración inmune y las vasculitis. Presentamos una serie de 13 pacientes infectados con HIV con osteonecrosis. El motivo de consulta fue dolor en grandes articulaciones. Cuatro eran alcoholistas, 8 tabaquistas y 9 tenían dislipemia. Once habían recibido esteroides en algún momento de la vida aunque sólo uno estaba recibiéndolos al momento del inicio del dolor. En 2 se detectaron anticuerpos anticardiolipina séricos. Doce tenían sida y recibían tratamiento antirretroviral de alta eficacia (11 con inhibidores de proteasa. Ellos lograron una adecuada recuperación inmunológica. Consideramos necesario incluir la osteonecrosis como diagnóstico diferencial de artralgia persistente en pacientes infectados con HIV e investigar infección por HIV en todo paciente con osteonecrosis sin claros factores predisponentes.Osteonecrosis, also known as avascular necrosis, is chiefly characterized by death of bone caused by vascular compromise. The true incidence of osteonecrosis in HIV-infected patients is not well known and the pathogenesis remains undefined. Hypothetical risk factors peculiar to HIV-infected individuals that might play a role in the pathogenesis of osteonecrosis include the introduction of protease inhibitors and resulting hyperlipidemia, the presence of anticardiolipin antibodies in serum leading to a hypercoagulable state, immune recovery and vasculitis. Hereby we present a series of 13 HIV-infected patients with osteonecrosis. The most common symptom upon presentation was arthralgia. The majority

    Full Text Available Abstract Background Patients with human immunodeficiency virus (HIV infection have an increased risk of cardiovascular diseases. Previous publications described pericardial effusion as one of the most common HlV-associated cardiac affiliations. The aim of the current study was to investigate if pericardial effusion still has a relevant meaning of HIV-infected patients in the era of antiretroviral therapy. Methods The HIV-HEART (HIV-infection and HEART disease study is a cardiology driven, prospective and multicenter cohort study. Outpatients with a known HIV-infection were recruited during a 20 month period in a consecutive manner from September 2004 to May 2006. The study comprehends classic parameters of HIV-infection, comprising CD4-cell count (cluster of differentiation and virus load, as well as non-invasive tests of cardiac diseases, including a thorough transthoracic echocardiography. Results 802 HIV-infected patients (female: 16.6% with a mean age of 44.2 ± 10.3 years, were included. Duration of HIV-infection since initial diagnosis was 7.6 ± 5.8 years. Of all participants, 85.2% received antiretroviral therapy. Virus load was detectable in 34.4% and CD4 - cell count was in 12.4% less than 200 cells/μL. Pericardial effusions were present in only two patients of the analysed population. None of the participants had signs of a relevant cardiovascular impairment by pericardial effusion. Conclusions Our results demonstrate that the era of antiretroviral therapy goes along with low rates of pericardial effusions in HIV-infected outpatients. Our findings are in contrast to the results of publications, performed before the common use of antiretroviral therapy.

    2012-11-01

    Full Text Available Purpose of the study: Observational studies have noted very high rates of low serum 25-hydroxyvitamin D [25(OHD3] levels in both general and HIV-infected populations. In HIV-infected patients, low 25(OHD3 levels are secondary to a combination of usual risk factors and HIV-specific risk factors, like antiretroviral therapy [1]. The objective of our study is to analyse the magnitude of vitamin D deficiency or insufficiency and the role of various factors such as age, sex, ethnicity, season, and antiretroviral medications in our cohort of HIV-infected patients. Methods: We prospectively collected data on 25-hydroxyvitamin D levels sampled between January 2009 and June 2011 from our cohort of 930 HIV-infected patients. Vitamin D dosage was performed using immunoassay (‘Diasorin’ - Saluggia, Italy. We divided vitamin D levels into 3 categories: 25-hydroxyvitamin D levels <20 mg/nl were considered deficient, insufficient between 20 and 29 ng/ml. Levels ≥30 ng/ml were defined as normal [2]. Data on demographic features (age, ethnicity, season, heterosexuality vs homosexuality, clinical features and laboratory findings (CD4 cell count, viral load, HAART, BMI were collected from patients’ medical records using our institutional database ‘Medical explorer v3r9, 2009’. Summary of results: Overall, 848 patients were included in our study (Table 1. Low levels of serum 25(OHD3 were seen in 89.3% of the study population, from which 69.5% were deficient and 19.8% were insufficient. On univariate analysis, female sex, high BMI, black African, heterosexuality, undetectable viral load and antiretroviral treatment were all predictors of vitamin D deficiency and insufficiency.

    International Nuclear Information System (INIS)

    Serum immunoreactive erythropoietin (SIE) and hemoglobin levels were measured in 152 patients infected with the human immunodeficiency virus. Anemia was present in 18% of asymptomatic patients who tested positive for the human immunodeficiency virus, 50% of patients with a condition related to the acquired immunodeficiency syndrome (AIDS), and 75% of patients with AIDS. The mean SIE level for untreated AIDS patients was greater than for patients who tested positive for human immunodeficiency virus or patients with an AIDS-related condition but not outside the normal range for SIE, and the incremental increase in SIE level for a given decline in hemoglobin level was much less in AIDS patients than in patients with uncomplicated iron deficiency anemia. Forty-two patients were treated with zidovudine, and the hemoglobin level fell 10 g/L or more in 48%. The data indicate that SIE level is inappropriately low in anemic AIDS patients. The ability of these patients to produce erythropoietin is intact and can be expressed with zidovudine therapy. However, even very high levels of SIE fail to stimulate erythropoiesis adequately

    Full Text Available Abstract Background Anemia is a common clinical finding in HIV-infected patients and iron deficiency or redistribution may contribute to the development of low hemoglobin levels. Iron overload is associated with a poor prognosis in HIV and Hepatitis C virus infections. Iron redistribution may be caused by inflammation but possibly also by hepatitis C co-infection. We examined the prevalence of anemia and its relation to mortality in a cohort of HIV patients in a setting where injecting drug use (IDU is a main mode of HIV transmission, and measured serum ferritin and sTfR, in relation to anemia, inflammation, stage of HIV disease, ART and HCV infection. Methods Patient characteristics, ART history and iron parameters were recorded from adult HIV patients presenting between September 2007 and August 2009 in the referral hospital for West Java, Indonesia. Kaplan-Meier estimates and Cox's regression were used to assess factors affecting survival. Logistic regression was used to identity parameters associated with high ferritin concentrations. Results Anemia was found in 49.6% of 611 ART-naïve patients, with mild (Hb 10.5 - 12.99 g/dL for men; and 10.5 - 11.99 g/dL for women anemia in 62.0%, and moderate to severe anemia (Hb Conclusion HIV-associated anemia is common among HIV-infected patients in Indonesia and strongly related to mortality. High ferritin with low sTfR levels suggest that iron redistribution and low erythropoietic activity, rather than iron deficiency, contribute to anemia. Serum ferritin and sTfR should be used cautiously to assess iron status in patients with advanced HIV infection.

    In Madagascar, the estimated incidence of tuberculosis is high (320 per 100,000) when human immunodeficiency virus (VIH) infection progress slowly. The authors have studied HIV seroprevalence in a group of tubercular patients and in two reference groups (general population and outpatients of the Clinical Biology Centre of Institut Pasteur). Circulation of HIV1 virus was observed with a low prevalence rate in all the 3 groups. There was no significant difference between tubercular patients and healthy population. Tubercular people ought to be a watch group for the epidemiological surveillance of HIV infection evolution in Madagascar. PMID:7575038

    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

    The diagnosis of neurosyphilis (NS) is a challenge, especially in HIV-infected patients, and the criteria for deciding when to perform a lumbar puncture (LP) in HIV-infected patients with syphilis are controversial. We retrospectively reviewed demographic, clinical, and laboratory data from 122 cases of HIV-infected patients with documented early syphilis who underwent an LP to rule out NS, and we evaluated 3 laboratory-developed validated real-time PCR assays, the Treponema pallidum particle agglutination (TPPA) assay, the fluorescent treponemal antibody absorption (FTA-ABS) assay, and the line immunoassay INNO-LIA Syphilis, for the diagnosis of NS from cerebrospinal fluid (CSF) samples of these patients. NS was defined by a reactive CSF-VDRL test result and/or a CSF white blood cell (WBC) count of >20 cells/μl. Thirty of the 122 patients (24.6%) had early NS. Headache, visual symptoms, a CD4 cell count of RPR) titers were not associated with early NS (P = 0.575). For the diagnosis of NS, the PCR, FTA-ABS, TPPA, and INNO-LIA assays had sensitivities of 58%, 100%, 68%, and 100%, specificities of 67%, 12%, 49%, and 13%, and negative predictive values of 85%, 100%, 84%, and 100%, respectively. Visual disturbances, headache, uncontrolled HIV-1 viremia, and a CD4 cell count of syphilis, while blood serum RPR titers were not; therefore, RPR titers should not be used as the sole criterion for deciding whether to perform an LP in early syphilis. When applied to CSF samples, the INNO-LIA Syphilis assay easily helped rule out NS. PMID:24088852

    Full Text Available BACKGROUND: Genotypic antiretroviral resistance testing (GRT in HIV infection with drug resistant virus is recommended to optimize antiretroviral therapy, in particular in patients with virological failure. We estimated the clinical effect, cost and cost-effectiveness of using GRT as compared to expert opinion in patients with antiretroviral treatment failure. METHODS: We developed a mathematical model of HIV disease to describe disease progression in HIV-infected patients with treatment failure and compared the incremental impact of GRT versus expert opinion to guide antiretroviral therapy. The analysis was conducted from the health care (discount rate 4% and societal (discount rate 2% perspective. Outcome measures included life-expectancy, quality-adjusted life-expectancy, health care costs, productivity costs and cost-effectiveness in US Dollars per quality-adjusted life-year (QALY gained. Clinical and economic data were extracted from the large Swiss HIV Cohort Study and clinical trials. RESULTS: Patients whose treatment was optimized with GRT versus expert opinion had an increase in discounted life-expectancy and quality-adjusted life-expectancy of three and two weeks, respectively. Health care costs with and without GRT were $US 421,000 and $US 419,000, leading to an incremental cost-effectiveness ratio of $US 35,000 per QALY gained. In the analysis from the societal perspective, GRT versus expert opinion led to an increase in discounted life-expectancy and quality-adjusted life-expectancy of three and four weeks, respectively. Health care costs with and without GRT were $US 551,000 and $US 549,000, respectively. When productivity changes were included in the analysis, GRT was cost-saving. CONCLUSIONS: GRT for treatment optimization in HIV-infected patients with treatment failure is a cost-effective use of scarce health care resources and beneficial to the society at large.

    Mar Masiá

    Full Text Available We aimed to assess whether oxidative stress is a predictor of mortality in HIV-infected patients.We conducted a nested case-control study in CoRIS, a contemporary, multicentre cohort of HIV-infected patients, antiretroviral-naïve at entry, launched in 2004. Cases were patients who died with available stored plasma samples collected. Two age and sex-matched controls for each case were selected. We measured F2-isoprostanes (F2-IsoPs and malondialdehyde (MDA plasma levels in the first blood sample obtained after cohort engagement.54 cases and 93 controls were included. Median F2-IsoPs and MDA levels were significantly higher in cases than in controls. When adjustment was performed for age, HIV-transmission category, CD4 cell count and HIV viral load at cohort entry, and subclinical inflammation measured with highly-sensitive C-reactive protein (hsCRP, the association of F2-IsoPs with mortality remained significant (adjusted OR per 1 log10 increase, 2.34 [1.23-4.47], P = 0.009. The association of MDA with mortality was attenuated after adjustment: adjusted OR (95% CI per 1 log10 increase, 2.05 [0.91-4.59], P = 0.080. Median hsCRP was also higher in cases, and it also proved to be an independent predictor of mortality in the adjusted analysis: OR (95% CI per 1 log10 increase, 1.39 (1.01-1.91, P = 0.043; and OR (95% CI per 1 log10 increase, 1.46 (1.07-1.99, P = 0.014, respectively, when adjustment included F2-IsoPs and MDA.Oxidative stress is a predictor of all-cause mortality in HIV-infected patients. For plasma F2-IsoPs, this association is independent of HIV-related factors and subclinical inflammation.

    Full Text Available Abstract Background Ceftriaxone is commonly used as an alternative antibiotic drug in treating syphilis but clinical data on its efficacy are limited. Objective: To evaluate the response of HIV-infected patients with active syphilis to treatment with penicillin or ceftriaxone. Methods A retrospective study involving 24 consecutive patients with a positive Veneral Disease Research Laboratory test (VDRL and at least one specific treponemal test. 12 patients were treated with different regimens of high-dose penicillin G for at least 2 weeks. Another 12 patients were treated with ceftriaxone 1-2 g per day intravenously for 10-21 days. Results After a median follow up of 18,3 months all patients of the penicillin-treated group and 11 of 12 ceftriaxone-treated patients showed a ≥ 4-fold decline in VDRL-titers; 91% of them already within 6 months after therapy. Conclusion Our serological data demonstrate a comparable efficacy of currently recommened penicillin and ceftriaxone treatment regimens for active syphilis in HIV-infected patients.

    Full Text Available Jose A VazquezDivision of Infectious Diseases, Henry Ford Hospital, Wayne State University School of Medicine, Detroit, MI, USAAbstract: Mucocutaneous candidiasis is frequently one of the f irst signs of human immunodeficiency virus (HIV infection. Over 90% of patients with AIDS will develop oropharyngeal candidiasis (OPC at some time during their illness. Although numerous antifungal agents are available, azoles, both topical (clotrimazole and systemic (fluconazole, itraconazole, voriconazole, posaconazole have replaced older topical antifungals (gentian violet and nystatin in the management of oropharyngeal candidiasis in these patients. The systemic azoles, are generally safe and effective agents in HIV-infected patients with oropharyngeal candidiasis. A constant concern in these patients is relapse, which is dependent on the degree of immunosuppression commonly seen after topical therapy, rather than with systemic azole therapy. Candida esophagitis (CE is also an important concern since it occurs in more than 10% of patients with AIDS and can lead to a decrease in oral intake and associated weight loss. Fluconazole has become the most widely used antifungal in the management of mucosal candidiasis. However, itraconazole and posaconazole have similar clinical response rates as fluconazole and are also effective alternative agents. In patients with fluconazole-refractory mucosal candidiasis, treatment options now include itraconazole solution, voriconazole, posaconazole, and the newer echinocandins (caspofungin, micafungin, and anidulafungin.Keywords: oropharyngeal candidiasis, esophageal candidiasis, HAART, antifungal agents, HIV, AIDS

    Full Text Available Nevirapine, a non-nucleoside reverse transcriptase inhibitor (NNRTI, is widely prescribed as a part of the combination therapy of human immunodeficiency virus (HIV infection because of its efficacy and good tolerability. Here, we report a case of Stevens-Johnson syndrome (SJS secondary to nevirapine. The patient had a diffuse, exfoliating exanthema with generalized bullous eruptions that involved the face, trunk and both extremities with elevated hepatic alanine aminotransferase and aspartate aminotransferase enzyme activities. The condition improved with stoppage of nevirapine-based highly active antiretroviral therapy (HAART regimen, so we attributed this adverse event to nevirapine. A strict vigilance of adverse drug reaction is required in HAART.

    2013-03-01

    Full Text Available Human Immunodeficiency virus (HIV infectionis associated with a variety of endocrine problems. Hypoadrenalism, hypothyroidism and hypogonadism are commonly found singly or in combination. Especially, male hypogonadism is very common in this population and may lead to weight loss, lethargy and other co morbidities. We undertook this cross sectional observational study to evaluate endocrine profile in HIV infected males in a sample Eastern Indian population. We also studied for any correlation of the endocrine dysfunctions with their immune status. We studied the blood hormone profiles along with blood CD4 counts. The bloods were drawn in fasting state and analysed using suitable high sensitivity assays. Standard statistical methods were used. We had 48 patients in our study. Among them, 33% had hypogonadism, 20% had hypothyroidism and 15 patients had diabetes. The hypogonadism was mainly hypogonadotropic. In other studies across the globe also, hypogonadism in HIV positive males is found to be significant. Our diabetic patients were not on protease inhibitors. We found some patients who had multiple endocrine dysfunctions. HIV infection is often associated with endocrine abnormalities. This aspect of the disease must be addressed during routine care of these patients. Hormone replacement must be individualized and may be needed for prolonged periods.

  18. Leiomyoma of the oesophagus in an HIV-infected patient

    International Nuclear Information System (INIS)

    A 30-year-old man was referred for investigation of a mediastinal mass found incidentally on a chest radiograph. He had a history of chronic cough and a 15-pack per year history of smoking. He was known to be HIV positive, having being diagnosed 7 years previously. The radiograph showed a left-sided opacity adjacent to the thoracic aorta. At the time of the referral the patient had been asymptomatic and denied dysphagia and odynophagia. Thoracic and abdominal CT scans revealed a distal oesophageal mass extending to the cardia of the stomach, with splenomegaly but no lymphadenopathy. Two direct endoscopic biopsies failed to provide a pathological diagnosis. A percutaneous transhepatic cutting biopsy under CT guidance provided tissue and the diagnosis. In the light of the benign nature of the neoplasm and the absence of symptoms, no further interventions were undertaken. The tumour tissue was submitted for microbiological analysis but was not found to contain Epstein-Barr virus. The patient was commenced on antiretroviral therapy. Follow-up CT scans in 1996 and 1998 showed no change in the mass characteristics; it remained 4 cm long and 3 cm wide with no local infiltration and no associated lymphadenopathy.

    Full Text Available Toxic epidermal necrolysis (TEN is a severe cutaneous adverse reaction to drugs, characterized by extensive detachment of epidermis and mucous membranes with a mortality of 30-40%. An increased occurrence of cutaneous drug reactions is seen in patients with human immunodeficiency virus (HIV infection. We present this case of TEN caused by ondansetron in an HIV-infected patient. A 24-year-old HIV-1-infected man on antitubercular therapy and cotrimoxazole, presented with extensive and confluent erosions involving the face, trunk, extremities and mucous membranes following the intake of oral ondansetron, ofloxacin and ornidazole. All the drugs were withdrawn and he was treated with intravenous dexamethasone and antibiotics with consequent healing of the erosions. However, the lesions recurred on inadvertent intake of oral ondansetron. He was treated with intravenous antibiotics, fluid resuscitation and supportive care. The skin lesions healed completely over 2 months with postinflammatory depigmentation and scarring, and the eye lesions healed with corneal opacities. We would like to emphasize that the drug most frequently associated with adverse drug reactions may be innocent in a given patient and the physician dealing with a suspected drug reaction must always remain unbiased regarding the causative drug.

All the drugs were withdrawn and he was treated with intravenous dexamethasone and antibiotics with consequent healing of the erosions. However, the lesions recurred on inadvertent intake of oral ondansetron. He was treated with intravenous antibiotics, fluid resuscitation and supportive care. The skin lesions healed completely over 2 months with postinflammatory depigmentation and scarring, and the eye lesions healed with corneal opacities. We would like to emphasize that the drug most frequently associated with adverse drug reactions may be innocent in a given patient and the physician dealing with a suspected drug reaction must always remain unbiased regarding the causative drug.

    Full Text Available Human immunodeficiency virus (HIV is known to influence the natural history of infections with certain hepatitis viruses and interactions between HIV and hepatitis viruses may potentiate HIV replication. There is high degree of epidemiological similarity between hepatitis B virus and HIV as regard to high-risk group and route of transmission. Transmission of hepatitis C virus (HCV through blood transfusion and intravenous drug abuse is well documented. Present study deals with the study of concurrent infection of HBV and HCV with HIV infection. In the study of 110 HIV seropositive patients, 34(30.4% were positive for HBV and 8(7.27% for HCV. The difference of concomitant infection was highly significant compared to controls. (p value < 0.0001. Heterosexual high risk behaviour was observed in 89(80.91% of 110 HIV positive patients, out of which 23(25.8% and 5(5.62% were HBsAg and anti-HCV positive respectively. History of transmission was unclear in remaining patients. Concomitant infection of HIV and HBV was found to be significantly more in the symptomatic group (40.68% compared to asymptomatic group (19.6%. As HIV infection is known to affect the natural history of both HBV and HCV infection, screening of their concurrent association is necessary.

    Full Text Available Abstract Background Aim of the study was to assess QTc interval by a 24-hour ECG recording in a group of HIV-infected individuals with a basal prolonged QTc. The risk factors associated with QTc prolongation and the indices of cardiovascular autonomic control were also evaluated. Methods A case–control study was performed using as cases 32 HIV-infected patients with prolonged (>440 msec QTc interval as assessed by Holter ECG, and as controls 64 HIV-infected subjects with normal QTc interval. Autonomic function was evaluated by heart rate variability analysis during 24-hour recording. Results Duration of HIV disease was significantly longer among cases than among controls (p=0.04. Waist/hip ratio was also higher among cases than among controls (p=0.05. Frequency domain analysis showed the absence of physiologic decrease of low frequency (LF in the night period in both cases and controls. The LF night in cases showed a statistically significant reduction when compared with controls (p=0.007. Conclusions In our study group, QTc interval prolongation was associated with a longer duration of HIV infection and with a greater waist/hip ratio. HIV patients with QTc interval prolongation and with a longer duration of HIV infection were more likely to have an impairment of parasympathetic and sympathetic cardiac component.

    Full Text Available Neutrophil to lymphocyte ratio (NLR has been shown to predict occurrence of cardiovascular events in the general population. The aim of our study was to evaluate the role of NLR to predict major cardiovascular disease (CVD events in HIV-infected subjects. We performed a retrospective cohort study of HIV-infected patients residing in the Local Health Authority (LHA of Brescia, northern Italy, from 2000 to 2012. The incidence of CVD events in HIV-positive patients was compared with that expected in the general population living in the same area, computing standardized incidence ratios (SIRs. To evaluate the predictive role of NLR, univariate and multivariate Cox regression models were applied, computing hazard ratios (HRs. A total of 3766 HIV-infected patients (mean age 38.1 years, 71.3% males were included (person-years 28768.6. A total of 134 CVD events occurred in 119 HIV-infected patients. A 2-fold increased risk (SIR 2.02 of CVD was found in HIV-infected patients compared to the general population. NLR levels measured at baseline and during follow-up were independently associated with CVD incidence, when also adjusting for both traditional CVD risk factors and HIV-related factors (HR 3.05 for NLR≥ 1.2. The area under the receiver operating characteristics (ROC curve showed a modest, not statistically significant, increase, from 0.81 to 0.83, with addition of NLR to Framingham risk score model covariates. In conclusion an elevated NLR is a predictor of risk CVD in HIV-infected patients, independently from the traditional CVD risk factors.

    2015-12-01

    Full Text Available One of the consistent findings among various studies on HIV has been simultaneous multiorgan dysfunction. Cardiovascular disorders are now most common cause of mortality worldwide. With more effective and widespread treatment of HIV in resource-rich settings, morbidity and mortality from non-AIDS-related events have surpassed those from AIDS-related events with cardiovascular diseases emerging as an important cause of death in HIV-infected patients relative to the decreasing incidence of opportunistic disease. Various studies have reported a 1.5-fold increase in the rate of cardiovascular events in HIV-infected individuals compared to control populations. MATERIAL AND METHODS The aim of the study was to the find the prevalence and types of different cardiovascular abnormalities in HIV positive patients and assess their association with CD4 counts. Consecutive 82 patients, HIV positive patients fulfilling the inclusion criteria and giving informed consent were included in the study. All patients were subjected to history taking and a detailed physical examination. Blood counts, renal function tests, lipid profile and CD4 counts were estimated and patients were subjected to 12-lead ECG, chest X-ray and 2D/Colour Doppler Echocardiogram. RESULTS Of the 82 patients studied 47.46% had evidence of cardiovascular involvement, out of which 12% had clinical features of heart failure while electrocardiographic changes were seen in 35% of patients in the form of sinus tachycardia (27%, QTc prolongation (10% and left sided chamber enlargements (6%. Echocardiographic abnormalities were noted in 39 patients (47.56% including fractional shortening associated with systolic dysfunction (26.8%. The mean CD4 count in patients with echocardiographic abnormalities was found to be 58.87±29.80, whereas in patients without echocardiographic abnormalities it was 136.53±38.80 (p<0.0001.

    OBJECTIVES: Antiretroviral therapy (ART) in HIV-infected patients is associated with increased cardiovascular risk. Circulating markers of endothelial dysfunction may be used to study early atherogenesis. The aim of our study was to investigate changes in such markers during initiation of ART...... before and after 2 and 14 months of ART. A control group of 30 healthy subjects was included. Values are mean+/-standard error of the mean. RESULTS: Prior to treatment, HIV-infected patients had elevated levels of sICAM-1 (296+/-24 vs. 144+/-12 ng/mL), tPAI-1 (18 473+/-1399 vs. 5490+/-576 pg/mL) and hs......CRP (28 060+/-5530 vs. 6665+/-2063 ng/mL) compared with controls (P<0.001). In contrast, sVCAM-1 and E-selectin did not differ between the groups. Initiation of ART resulted in significantly lower levels of E-selectin (15.1+/-0.8; P<0.01), sICAM-1 (248+/-12 ng/mL; P<0.05), sVCAM-1 (766+/-33 ng/mL; P<0...

    Alessandro Soria

    Full Text Available BACKGROUND: In HIV-infected individuals, mechanisms underlying unsatisfactory immune recovery during effective combination antiretroviral therapy (cART have yet to be fully understood. We investigated whether polymorphism of genes encoding immune-regulating molecules, such as killer immunoglobulin-like receptors (KIR and their ligands class I human leukocyte antigen (HLA, could influence immunological response to cART. METHODS: KIR and HLA frequencies were analyzed in 154 HIV-infected and cART-treated patients with undetectable viral load divided into two groups: 'immunological non responders' (INR, N = 50, CD4(+ T-cell count 350/mm(3. Molecular KIR were typed using polymerase chain reaction-based genotyping. Comparisons were adjusted for baseline patient characteristics. RESULTS: The frequency of KIR2DL3 allele was significantly higher in FR than in INR (83.7% vs. 62%, P = 0.005. The functional compound genotype HLA-C1(+/KIR2DL3(+, even at multivariable analysis, when adjusted for nadir CD4(+ T-cell count, was associated with reduced risk of INR status: odds ratio (95% Confidence Intervals 0.34 (0.13-0.88, P = 0.03. CONCLUSIONS: Reduced presence of the inhibitory KIR2DL3 genotype detected in INR might provoke an imbalance in NK function, possibly leading to increased immune activation, impaired killing of latently infected cells, and higher proviral burden. These factors would hinder full immune recovery during therapy.

    Full Text Available Context Pancreatitis is a common complication of acquired immunodeficiency syndrome. The most common causes of acute pancreatitis in an HIV population are medication and opportunistic infections. Case report We report the case of a young, untreated, HIV-infected female who presented with acute pancreatitis of unknown origin. Unique to this case are the autoimmune pancreatitislike features on imaging studies associated with renal mass-like lesions and lymph node involvement as well as the favorable outcome using highly active antiretroviral therapy alone. Conclusion In HIV-infected patients, acute pancreatitis may present on imaging studies as autoimmune pancreatitis. In patients with uncontrolled HIV infection and imaging studies suggestive of autoimmune pancreatitis, direct HIV-related inflammation should be considered after exclusion of all other causes of pancreatitis.

The finding that patients mobilized cells with an impaired proliferation to PWM during and after adrenalin infusion has possible clinical relevance for HIV infected patients during pathological stressful conditions, such as...

  20. Arginase activity in the blood of patients with visceral leishmaniasis and HIV infection.

    Directory of Open Access Journals (Sweden)

    Yegnasew Takele

    Full Text Available BACKGROUND: Visceral leishmaniasis is a parasitic disease associated with high mortality. The most important foci of visceral leishmaniasis in Ethiopia are in the Northwest and are predominantly associated with high rates of HIV co-infection. Co-infection of visceral leishmaniasis patients with HIV results in higher mortality, treatment failure and relapse. We have previously shown that arginase, an enzyme associated with immunosuppression, was increased in patients with visceral leishmaniasis and in HIV seropositive patients; further our results showed that high arginase activity is a marker of disease severity. Here, we tested the hypothesis that increased arginase activities associated with visceral leishmaniasis and HIV infections synergize in patients co-infected with both pathogens. METHODOLOGY/PRINCIPAL FINDINGS: We recruited a cohort of patients with visceral leishmaniasis and a cohort of patients with visceral leishmaniasis and HIV infection from Gondar, Northwest Ethiopia, and recorded and compared their clinical data. Further, we measured the levels of arginase activity in the blood of these patients and identified the phenotype of arginase-expressing cells. Our results show that CD4(+ T cell counts were significantly lower and the parasite load in the spleen was significantly higher in co-infected patients. Moreover, our results demonstrate that arginase activity was significantly higher in peripheral blood mononuclear cells and plasma of co-infected patients. Finally, we identified the cells-expressing arginase in the PBMCs as low-density granulocytes. CONCLUSION: Our results suggest that increased arginase might contribute to the poor disease outcome characteristic of patients with visceral leishmaniasis and HIV co-infection.

    Liver disease associated with hepatitis C virus (HCV) is a significant and increasing cause of death for HIV-infected patients, but limited data exist to guide treatment of coinfection. Increased knowledge of HCV disease and its treatment among HIV care practitioners and adoption of routine care procedures can improve management of coinfected patients. This article discusses HCV screening and diagnosis, counseling and health care maintenance, and evaluation for and supervision of treatment in HIV-seropositive patients who are coinfected with HCV. The experiences of the Oakland, California-based Alameda County Medical Center, which treats more than 200 coinfected patients, are detailed and serve as the basis for suggested management strategies. This article summarizes a presentation given by Kathleen A. Clanon, MD at the November 2002 International AIDS Society-USA course in San Diego. PMID:12717042

    The introduction of potent combination antiretroviral therapy (cART) has had a remarkable impact on the natural history of HIV infection, leading to a dramatic decline in the mortality rate and a considerable increase in the life expectancy of HIV-positive people. However, cART use is frequently associated with several metabolic complications, mostly represented by lipid metabolism alterations, which are reported very frequently among persons treated with antiretroviral agents. In particular, hyperlipidaemia occurs in up to 70%-80% of HIV-positive subjects receiving cART and is mainly associated with specific antiretroviral drugs belonging to three classes of antiretroviral agents: NRTIs, NNRTIs and PIs. The potential long-term consequences of cART-associated dyslipidaemia are not completely understood, but an increased risk of premature coronary heart disease has been reported in HIV-infected patients on cART, so prompt correction of lipid metabolism abnormalities is mandatory in this population. Dietary changes, regular aerobic exercise and switching to a different antiretroviral regimen associated with a more favourable metabolic profile are the first steps in clinical management, but lipid-lowering therapy with fibrates or statins is often required. In this case, the choice of hypolipidaemic drugs should take into account the potential pharmacokinetic interactions with many antiretroviral agents. PMID:26846208

    Full Text Available Abstract Background Literature on the spectrum of opportunistic disease in human immunodeficiency virus (HIV-infected patients from developing countries is sparse. The objective of this study was to document the spectrum and determine the frequency of various opportunistic infections (OIs and non-infectious opportunistic diseases, in hospitalised HIV-infected patients from north India. Methods One hundred and thirty five consecutive, HIV-infected patients (age 34 ± 10 years, females 17% admitted to a tertiary care hospital in north India, for the evaluation and management of an OI or HIV-related disorder between January 2000 and July 2003, were studied. Results Fever (71% and weight loss (65% were the commonest presenting symptoms. Heterosexual transmission was the commonest mode of HIV-acquisition. Tuberculosis (TB was the commonest OI (71% followed by candidiasis (39.3%, Pneumocystis jiroveci pneumonia (PCP (7.4%, cryptococcal meningitis and cerebral toxoplasmosis (3.7% each. Most of the cases of TB were disseminated (64%. Apart from other well-recognised OIs, two patients had visceral leishmaniasis. Two cases of HIV-associated lymphoma were encountered. CD4+ cell counts were done in 109 patients. Majority of the patients (82.6% had CD4+ counts Conclusions A wide spectrum of disease, including both OIs and non-infectious opportunistic diseases, is seen in hospitalised HIV-infected patients from north India. Tuberculosis remains the most common OI and is the commonest cause of death in these patients.

    Full Text Available BACKGROUND: HIV infection is an emerging problem in Laos. We conducted the first prospective study on intestinal parasites, including opportunistic protozoa, in newly diagnosed HIV infected patients, with or without diarrhea. The aims were to describe the spectrum of infections, to determine their prevalence and to assess their associations with diarrhea, CD4 cell count, place of residence and living conditions. METHODOLOGY: One to three stool samples over consecutive days were obtained from 137 patients. The Kato thick smear method, formalin-ethyl concentration and specific stains for coccidia and microsporidia diagnosis were performed on 260 stool samples. Baseline characteristics regarding relevant demographics, place of residence and living conditions, clinical features including diarrhea, were collected using a standardized questionnaire. PRINCIPAL FINDINGS: The 137 patients were young (median age: 36 years and severely immunocompromised (83.9% at WHO stage 3 or 4, median CD4 cell count: 41/mm3. Diarrhea was present in 43.0% of patients. Parasite infection was found in 78.8% of patients, infection with at least two species in 49.6%. Prevalence rates of protozoan and helminth infections were similar (54.7% and 58.4% respectively. Blastocystis sp. was the most frequent protozoa (26.3%. Cryptosporidium sp., Cytoisospora belli and microsporidia, found at low prevalence rates (6.6%, 4.4%, 2.9%, respectively, were described for the first time in Laos. Cryptosporidium sp. was associated with persistent diarrhea. Strongyloides stercoralis was the most prevalent helminth following Opisthorchis viverrini (20.4% and 47.5% respectively. The most immunocompromised patients, as assessed by a CD4 count ≤ 50 cells/mm3, were more likely to be infected with intestinal parasites. CONCLUSIONS/SIGNIFICANCE: HIV infection was mainly diagnosed at an advanced stage of immunosuppression in Lao patients. Intestinal parasite infections were highly prevalent

The present study aimed to estimate ART adherence among HIV-infected patients in the Kathmandu District of Nepal, and to determine the factors associated with ART adherence.Patients and methods: This study included 316 HIV-infected patients attending three ART centers in the Kathmandu District. Information on sociodemographic characteristics, socioeconomic status, and ART use for the previous 7 days was collected via interview. Participants were considered adherent if they reported taking ≥95% of their ART as prescribed. The association between explanatory variables and ART adherence was measured using logistic regression and reported as odds ratios (OR with 95% confidence intervals (CI.Results: Male participants accounted for 64.6% (n=204. Overall ART adherence was 86.7%. ART adherence in men and women were 84.3% and 91.1%, respectively. Age (OR 1.04; 95% CI 1.00–1.09, travel time to ART centers (OR 1.38; 95% CI 1.12–1.71, history of illegal drug use (OR 3.98; 95% CI 1.71–9.24, and adverse effects (OR 4.88; 95% CI 1.09–21.8, were all independently and negatively associated with ART adherence. Use of reminder tools (OR 3.45; 95% CI 1.33–8.91 was independently and positively associated with ART adherence.Conclusion: The observed ART adherence in this study is encouraging. Travel time to ART centers, self-reported adverse effects, illegal drug use, and not using reminder tools were the major determinants of ART adherence. Interventions that take these factors into account could further improve ART

    Christopher J Hoffmann

    Full Text Available Liver disease epidemiology in sub-Saharan Africa has shifted as a result of HIV and the increased use of antiretroviral therapy leading to a need for updated data on common causes of liver disease. We retrospectively reviewed records from all hospitalized patients who had liver biopsy at a single hospital in South Africa from 2001 to 2009 and compared diagnosis by HIV status. During the period of study 262 patients had liver biopsy, 108 (41% were HIV-infected, 25 (10% were HIV-sero-negative, and 129 (49% had unknown or unrecorded HIV status. Overall 81% of biopsies provided additional diagnostic data. Malignancy was the most common finding reported on 56 (21% biopsies followed by granuloma or TB, hepatic steatosis, and fibrosis or cirrhosis. HIV-infected patients were more likely to have granulomas and steatosis. Half of patients with granulomas were already on TB treatment, suggesting paradoxical reactions or drug induced liver injury may have been important causes of liver inflammation among these patients. We note that TB, paradoxical reactions during TB treatment, possible drug induced liver injury, and hepatic steatosis are important causes of liver pathology among HIV-infected hospitalized patients with unclear etiology of liver disease after initial assessment. Among HIV sero-negative patients, malignancy was the major cause of liver disease. Our findings re-enforce the importance of TB as a diagnosis among HIV-infected individuals.

    Full Text Available Background. Although access to HAART has prolonged survival and improved quality of life, HIV-infected patients with severe immunosuppression or comorbidities may develop complications that require critical care support. Our objective is to evaluate the etiology of respiratory failure in patients with HIV infection admitted to the ICU, its relationship with the T-lymphocytes cell count as well as the use of HAART, and its impact on outcome. Methods. A single-center, prospective, and observational study among all patients with HIV-infection and respiratory failure admitted to the ICU from December 1, 2011, to February 28, 2013, was conducted. Results. A total of 42 patients were admitted during the study period. Their median CD4 cell count was 123 cells/μL (mean 205.7, range 2.0–694.0, with a median HIV viral load of 203.5 copies/mL (mean 58,676, range <20–367,649. At the time of admission, 23 patients (54.8% were receiving HAART. Use of antiretroviral therapy at ICU admission was not associated with survival, but it was associated with higher CD4 cell counts and lower HIV viral loads. Twenty-five patients (59.5% had respiratory failure secondary to non-HIV-related diseases. Mechanical ventilation was required in 36 patients (85.1%. Thirteen patients (31.0% died. Conclusions. Noninfectious etiologies of respiratory failure account for majority of HIV-infected patients admitted to ICU. Increased mortality was observed among patients with sepsis as etiology of respiratory failure (HIV related and non-AIDS related, in those receiving mechanical ventilation, and in patients with decreased CD4 cell count. Survival was not associated with the use of HAART. Complementary studies are warranted to address the impact of HAART on outcomes of HIV-infected patients with respiratory failure admitted to ICU.

    Full Text Available Abstract. A distribution mode for allelic variants of cytokine genes was evaluated in 184 patients with slow viral infections, including 97 patients with chronic herpetic infection and 87 HIV-infected patients. Using modern methods of immunogenetics, we have found that relative risks of recurrent course and poor outcome of infection are positively associated with AA promoter region genotype and AA promoter genotype of +874 A/T polymorphism in the IFNG gene. Immunogenetic factors associated with protective effect in slow virus infections, include G allele of TNFA gene (G-308A SNP, and T allele/TT genotype of promoter region in  the IFNG gene (+874 A/T SNP.

    Full Text Available BACKGROUND: Algorithms for bone mineral density (BMD management in HIV-infected patients are lacking. Our objective was to assess how often a dual-energy x-ray absorptiometry (DXA scan should be performed by assessing time of progression to osteopenia/osteoporosis. METHODS: All DXA scans performed between 2000 and 2009 from HIV-infected patients with at least two DXA were included. Time to an event (osteopenia and osteoporosis was assessed using the Kaplan-Meier method. Strata (tertiles were defined using baseline minimum T scores. Differences between strata in time to an event were compared with the log-rank test. RESULTS: Of 391 patients (1,639 DXAs, 49.6% had osteopenia and 21.7% osteoporosis at their first DXA scan. Of the 112 (28.6% with normal BMD, 35.7% progressed to osteopenia; median progression time was 6.7 years. These patients were stratified: "low-risk" (baseline minimum T score >-0.2 SD, "middle-risk" (between -0.2 and -0.6 SD, and "high-risk" (from -0.6 to -1 SD; median progression time to osteopenia was 8.7, >7.2, and 1.7 years, respectively (p8.5 years. Progression time was >8.2 years in "low-risk" tertile (T score between -1.1 and -1.6 SD, >8.5 years in "middle-risk" (between -1.6 and -2, and 3.2 years in "high-risk" (from -2 to -2.4 (p<0.0001. CONCLUSIONS: Our results may help to define the BMD testing interval. The lowest T score tertiles would suggest recommending a subsequent DXA in 1-2 years; in the highest tertiles, ≥6 years. Early intervention in patients with bone demineralization could reduce fracture-related morbidity/mortality.

    Full Text Available The microsporidian species Enterocytozoon bieneusi is a major cause of chronic diarrhea and malabsorption in patients with AIDS. Genotyping was performed on seven E. bieneusi strains for the first time in Tunisia. All the strains were isolated from stool samples of humans with immunodeficiency virus (HIV infection. Analysis of the ribosomal RNA gene internal transcribed spacer (rDNA ITS allowed the identification of three distinct genotypes previously described in other studies. Genotypes D and B were characterized in four and two respectively. The Peruvian genotype (Peru 8 was detected in the last isolate. These results indicate a genetic diversity in E. bieneusi strains from HIV Tunisian patients and suggest the coexistence of both zoonotic and anthroponotic route of transmission.

    Full Text Available Introduction. Infections of the gastrointestinal tract are caused by a wide range of fungi, viruses and bacteria. The great value has the ratio of microorganisms. There are certain regularities in microecological system of intestinal microflora. Thus, bifidous bacteria should be more than lactobacterium; enterobacteria – more than enterococcus; E.faecalis more than E.faecium. However, these differences should be at least one or two orders of magnitude. An important indicator is the ratio of enterobacteria and enterococcus. Material & methods. In the paper were used following materials and methods: bacteriological and statistical. The conditions of intestinal microbiocenosis were evaluated according to the methodical instructions about researches of fecal masses on dysbiosis and modern methods of correction of intestinal dysbiosis that included identifying of anaerobic and facultative anaerobic microorganisms, staphylococci, enterococci, opportunistic enterobacteria, Proteus spp., Klebsiella spp., P.aeruginosa, C.albicans. Bacterial cultures were identified by standard techniques. Statistical analysis of the results was performed by the standard method of determining the average value and its standard deviation (M + m and Student's t-test. The reliability of the difference was evaluated at the level of probability p 104 CFU/grams in 11,8 + 5,53%, S.epidermidis in amount of > 105 CFU/grams in 32,4 + 8,03%, C.albicans in amount of > 104 CFU/grams in 11,1 + 6,59% and 1 patient had Clostridium in amount > 103 CFU/grams, which was 3 + 2,93%. These data show that patients with HIV infection is detected at the same time reducing number of anaerobic microflora (bifidus bacteria and lactobacilli and aerobic microflora, a leading representative of which is intestinal E.coli irrespective of the clinical stage of the disease. Association of these microorganisms is 56%. To this attach indicators of reduction E.faecalis and E.faecium. Taking into account the

    AIMS QTc interval prolongation and torsades de pointes have been reported in HIV-infected patients. Protease inhibitors (PIs) are suspected to contribute to this adverse reaction. However, many factors can prolong QTc interval. We examined factors influencing QTc duration in HIV-infected patients. METHODS Unselected HIV-infected patients (n = 978) were enrolled in this prospective, single-centre cross-sectional study. Variables related to infection and treatments were collected. A digital electrocardiographic record was recorded in each patient and QT interval duration was measured and corrected using both Bazett's (QTcB) and Fridericia's (QTcF) formula. Results were analysed with a multivariable linear model. RESULTS After excluding arrhythmias and complete bundle branch blocks, QT interval was measured in 956 patients. The mean (SD) QTcB was 418 ms (23) and QTcF was 405 ms (20). QTc was found prolonged (>450 ms in women and >440 ms in men) in 129 [13.5%; 95% confidence interval (CI) 11.5, 15.8] and 38 (4%; 95% CI 2.9, 5.4) patients using Bazett and Fridericia corrections, respectively. On multivariable analysis, incomplete bundle branch block, ventricular hypertrophy, signs of ischaemic cardiopathy, female gender, White ethnic origin and age were significantly associated with QTc prolongation. The only HIV variable independently associated with QTc prolongation was the duration of infection (P = 0.023). After adjustment, anti-HIV treatment, in particular PI (P = 0.99), was not associated with QTc prolongation. CONCLUSIONS Although PIs block in vitro hERG current, they are not independently associated with QTc interval prolongation. Prolonged QTc interval in HIV-infected patients is primarily associated with factors commonly known to prolong QT and with the duration of HIV infection. PMID:19076152

    DING proteins constitute an interesting family, owing to their intriguing and important activities. However, after a decade of research, little is known about these proteins. In humans, at least five different DING proteins have been identified, which were implicated in important biological processes and diseases, including HIV. Indeed, recent data from different research groups have highlighted the anti-HIV activity of some DING representatives. These proteins share the ability to inhibit the transcriptional step of HIV-1, a key step of the viral cycle that is not yet targeted by the current therapies. Since such proteins have been isolated from humans, we undertook a comprehensive study that focuses on the relationship between these proteins and HIV-infection in an infectious context. Hence, we developed a home-made ELISA for the quantification of the concentration of DING proteins in human serum. Using this method, we were able to determine the concentration of DING proteins in healthy and HIV-infected patients. Interestingly, we observed a significant increase of the concentration of DING proteins in non treated and treated HIV-infected patients compared to controls. In addition, cell cultures infected with HIV also show an increased expression of DING proteins, ruling out the possible role of antiretroviral treatment in the increase of the expression of DING proteins. In conclusion, results from this study show that the organism reacts to HIV-infection by an overexpression of DING proteins. PMID:22427948

  1. Immunotherapy of HIV-infected patients with Gc protein-derived macrophage activating factor (GcMAF).

    Serum Gc protein (known as vitamin D3-binding protein) is the precursor for the principal macrophage activating factor (MAF). The MAF precursor activity of serum Gc protein of HIV-infected patients was lost or reduced because Gc protein is deglycosylated by alpha-N-acetylgalactosaminidase (Nagalase) secreted from HIV-infected cells. Therefore, macrophages of HIV-infected patients having deglycosylated Gc protein cannot be activated, leading to immunosuppression. Since Nagalase is the intrinsic component of the envelope protein gp120, serum Nagalase activity is the sum of enzyme activities carried by both HIV virions and envelope proteins. These Nagalase carriers were already complexed with anti-HIV immunoglobulin G (IgG) but retained Nagalase activity that is required for infectivity. Stepwise treatment of purified Gc protein with immobilized beta-galactosidase and sialidase generated the most potent macrophage activating factor (termed GcMAF), which produces no side effects in humans. Macrophages activated by administration of 100 ng GcMAF develop a large amount of Fc-receptors as well as an enormous variation of receptors that recognize IgG-bound and unbound HIV virions. Since latently HIV-infected cells are unstable and constantly release HIV virions, the activated macrophages rapidly intercept the released HIV virions to prevent reinfection resulting in exhaustion of infected cells. After less than 18 weekly administrations of 100 ng GcMAF for nonanemic patients, they exhibited low serum Nagalase activities equivalent to healthy controls, indicating eradication of HIV-infection, which was also confirmed by no infectious center formation by provirus inducing agent-treated patient PBMCs. No recurrence occurred and their healthy CD + cell counts were maintained for 7 years. PMID:19031451

    Although crucial for efficacy of pharmacotherapy, adherence to prescribed medication regimens for both antiretrovirals and antidepressants is often suboptimal. As many depressed HIV-infected individuals are prescribed both antiretrovirals and antidepressants, it is important to know whether correlates of nonadherence are similar or different across type of regimen. The HIV Translating Initiatives for Depression into Effective Solutions (HI-TIDES) study was a single-blinded, longitudinal, randomized controlled effectiveness trial comparing collaborative care to usual depression care at three Veterans Affairs HIV clinics. The current investigation utilized self-report baseline interview and chart-abstracted data. Participants were 225 depressed HIV-infected patients who were prescribed an antidepressant (n=146), an antiretroviral (n=192), or both (n=113). Treatment adherence over the last 4 days was dichotomized as "less than 90% adherence" or "90% or greater adherence." After identifying potential correlates of nonadherence, we used a seemingly unrelated regression (SUR) bivariate probit model, in which the probability of adherence to HIV medications and the probability of adherence to antidepressant medications are modeled jointly. Results indicated that 75.5% (n=146) of those prescribed antiretrovirals reported 90%-plus adherence to their antiretroviral prescription and 76.7% (n=112) of those prescribed antidepressants reported 90%-plus adherence to their antidepressant prescription, while 67% of those prescribed both (n=113) reported more than 90% adherence to both regimens. SUR results indicated that education, age, and HIV symptom severity were significant correlates of antiretroviral medication adherence while gender and generalized anxiety disorder diagnosis were significant correlates of adherence to antidepressant medications. In addition, antiretroviral adherence did not predict antidepressant adherence (β=1.62, p=0.17), however, antidepressant adherence

    Objective: In Iran, psychological aspect of HIV infection is poorly understood. The purposes of this study were to evaluate sexual dysfunction, depression rate and health-related quality of life and evaluate the association between sexual dysfunction, depression and quality of life in a group of HIV+ subjects in Shiraz, Iran. Methods: In this cross-sectional study, 278 male HIV-positive patients who had referred to voluntary counseling and testing and methadone maintenance therapy centers were recruited based on convenience sampling from May to October 2010. The purpose of the study was explained and interested individuals provided informed consent and completed validated questionnaires [Medical Outcomes Study Short Form-36 (SF-36(, Brief Male Sexual Function Inventory (BMSFI), Beck Depression Inventory-short form(BDI)] to assess overall health related quality of life (HRQOL), sexual function, and depression. Results: Average age of the participants was 34.9 ± 10.7 years and 37.5% were severely depressed. Ordinal logistic regression indicated that sexual drive (-0.15; CI: -0.28 to -0.027), ejaculation (-1.91, CI: -2.71 to -1.12), and problem assessment (-0.098, CI: -0.17 to -0.02) had significant effect on depression type. Depression was significantly correlated with poorer quality of life in all domains. Pearson’s correlation coefficients between the BMSFI and the domains of SF-36 indicated that sexual drive (r= 0.215), ejaculation (r= 0.297) and problem assessment (r= 0.213) were significantly correlated with emotional wellbeing. Conclusion: Sexual function and depression showed association with quality of life. Effective treatment of depression and sexual function may improve the quality of life of HIV-infected person. Declaration of interest: None. PMID:24644501

    31 Italian HIV-infected patients with newly diagnosed tuberculosis (TB) were reviewed to verify the effectiveness of the most common antituberculosis drugs. The patients were mostly intravenous drug addicts (90%), and 14 (45%) had recently been in prison. 5 patients (16%) had pulmonary TB, 15 (48%) had both pulmonary and extrapulmonary involvement, and 11 (30%) had extrapulmonary disease alone. 6 patients received the association of HRZ, and a 4-drug association including ethambutol was given to an additional 7 patients. The remaining 18 patients were administered the association of HRE. Response to therapy was good in 13 patients (42%), and lacking or delayed in 18 patients (58%). Treatment failure was partly related to the increased occurrence in our area of Mycobacterium tuberculosis strains resistant to the first-line anti-tuberculosis drugs. These observations, along with the need of a faster response to therapy than that currently obtained for TB in AIDS and in view of epidemiological effects, should prompt the definition of alternative therapeutic and prophylactic regimens.

    Full Text Available Purpose of the study: Co-infection with HIV / hepatitis C virus (HCV occurs commonly due to similar routes of transmission, mainly in MSM and IVDU patients. In 2009, EACS guidelines introduced the notion of systematic annual HCV screening among HIV-infected patients. This study evaluated staff knowledge, adherence to HCV screening recommendations and seroconversion rates for HCV in our HIV Reference Centre. Methods: Eight physicians (HIV specialists were interviewed on recommendations and perceived adherence to EACS clinical guidelines on HCV screening [1]. We then reviewed medical records of our cohort of HIV-infected patients on regular follow-up in our centre each year, from 2008 to 2011. We considered a patient to be on regular follow-up when records showed at least two clinical reviews and one HIV viral load testing during the year. Demographic features and HCV serology tests were collected from the operating software of our institution (Medical Explorer v3r9, 2008. Diagnosis of HCV was retained when serology became positive and HCV RNA was detected. Summary of results: Though knowledge of current guidelines was excellent (100%, staff claimed a 87.5% adherence rate to these recommendations. Rate of screening rose gradually between 2008 and 2011, especially after introduction of EACS guidelines in 2009 (Table 1 and Fig. 1. The maximal screening rate was in 2011, with 44% of patients tested among the general HIV population and 57% among MSM bisexual patients. This trend was statistically significant in both populations (p<0.01. The year 2011 displayed a marked increase in diagnosis of HCV infection, with 8 new patients diagnosed in a 963-patient-large cohort (all were MSM. Conclusion: In our centre, knowledge of EACS guidelines on screening for HCV was good but adherence to these recommendations is poor, though it improves over time. It is consistent with published rates of compliance to clinical guidelines on screening policies for HCV among

A negative test was found in 452 samples and an indeterminate results in 40 (7.4% but neither were associated with a low CD4 count. A positive test was found in 10% (50/502 individuals. All patients with positive tests were referred to the TB specialist, 47 (94% had a chest radiograph and 46 (92% attended the TB clinic. Two had culture-positive TB and a third individual with features of active TB was treated. 40 started and 38 completed preventive treatment. One patient who completed preventive treatment with isoniazid monotherapy subsequently developed isoniazid-resistant pulmonary tuberculosis. No patient with a negative test has developed TB. Conclusions We found an overall prevalence of latent TB infection of 10% through screening for TB in those with HIV infection and without symptoms, and a further 1% with active disease, a yield greater than typically found in contact tracing. Acceptability of preventive treatment was high with 85% of those with latent TB infection eventually completing their TB chemotherapy regimens. IGRA-based TB screening among HIV-infected individuals was feasible in the clinical setting and assisted with appropriate management (including preventive

    Full Text Available Introduction: Polymorphisms in some host genes have a significant impact on susceptibility to HIV-1 infection and rate of disease progression (1, 2. The purpose of the current sub-study was to find out the relationship between polymorphisms in genes involved in the lipid metabolism and the CD4/CD8 T-cell counts. Methods: Sub-study of a cross-sectional, observational study conducted in 468 patients with HIV infection attended at the outpatient clinic to investigate individual genetic predisposition to atherogenic dyslipidemia (AD. All patients were genetically characterized and all polymorphisms were in Hardy–Weinberg equilibrium. Thirteen polymorphisms were selected from nine genes: APOA5 (rs662799 and rs3135506; APOC3 (rs5128 and rs4520; LPL (rs328 and rs268; CETP (rs708272; HL (rs1800588; MTP (rs1800591; APOE (rs7412 and rs429358; LRP5 (rs7116604; and VLDLR (rs1454626. Lipid and lipoprotein parameters, CD4 and CD8 T-cell counts and plasma HIV-RNA were determinate. The statistical analysis was performed using SPSS statistical software version 19 (SPSS Inc., Chicago, IL, USA. Results: We studied 468 HIV-infected patients (men, 77%, with a mean (SD age of 45.9 (19.7 years. The mean CD4 T-cell count and nadir CD4 was 547 (459 and 193 (159 cells/µL, respectively; 78.7% of participants were virologically suppressed. Patients carrying rs3135506 in the APOA5 gene presented a 9% increase in circulating TG levels (p=0.002 and 10% decrease in HDLc levels (p=0.005. Such association of APOA5 towards dyslipidemia was accompanied by a 21% decrease of the CD4 T-cell count (p=0.024 and a 19% increase in CD8 T-cell count (p=0.002 in carriers of the rare allele in the APOA5 rs662799 polymorphism adjusted by age and gender. Patients carrying the rare allele in rs5128 (APOC3 had a 16% decrease in circulating CD4 T cells (p=0.029; patients carrying rs1800591 (MTP had a 29% decrease in CD4 T cells and 14% decrease in CD8 T cells (p=0.018 and p=0.008, respectively

    In the last two years the Romanian adult population infected with the human immunodeficiency virus (HIV) has increased due to sexual transmission, both heterosexual and homosexual. The case presented is that of a 33 year-old man, admitted to the Infectious Diseases Hospital in Iasi with acute respiratory failure and a confirmation of Kaposi's sarcoma. Tests later proved positive for HIV, the patient being included in the stage AIDS C3 (acute immunodeficiency syndrome). The respiratory failure was suspected to be caused by Pneumocystis carinii and cotrimoxazol therapy, oxygen therapy and anti-retroviral therapy were established. He was also referred to the oncology hospital for treatment of Kaposi's sarcoma. The patient's adherence to therapy was influenced by a strong doctor-patient relationship, as well as by psychological counseling and support. Creating a functional doctor-patient-psychologist team is key throughout the HIV-positive patient's existence, for supporting long term adherence to therapy and acceptance of the diagnosis. This case highlights the need for a strong psychosocial compartment in every medical center that deals with HIV-infected individuals. PMID:27125083

    Purpose: The study aims at detecting risk factors for developing peripheral neuropathy in Romanian HIV infected subjects. Material/Methods: retrospective study (january 1990-january 2009) who analyzed data from patients hospitalized in the Regional Center Craiova. We have compared 26 patients (group N) diagnosed with peripheral neuropathy  with 40 patients (group C) without neuropsychological sufferings, randomly selected. We have analysed: age, height, HIV mode of transmission, AIDS status, the average and nadir of CD4 lymphocytes, the mean viral load, the average duration of antiretroviral treatment (ART), use and duration of use of d-drugs, the presence of certain coinfection, diabetes or ethanol abuse. Results: the following differences were statistically significant: age (31,54±14,64 vs 23,9±12,03 years, p=0.024), HIV mode of transmission  (parenteral/sexual: 13/13 vs 28/8, p = 0.044), the monitoring time duration (5,31±3,77 vs 7,75±5,4 years, p=0.043), median ART duration (37,2±9,66 vs 45,12±8,75 months, p=0.001). Close to the threshold of statistical significance are the CD4 nadir (97,33±65,6 vs 123,15±43,35 cells/mm3, p=0.058) and duration of use of d–drugs (22,5±31,94 vs 12,24±8,6 months, p=0.057). Odds ratio (OR) and relative risk (RR) increase with age. ROC analysis for the study group establishes a threshold difference of 29 years (sensitivity 50%, specificity 80%). Conclusions: higher age and advanced immunosupression are the most important risk factors for developing symptomatic peripheral neuropathy in Romanian HIV infected patients; taking into account the small number of cases studied, although not statistically significant, it should be noted the CD4 nadir and the length of d-drug use.

    Full Text Available Introduction: Successfully treated HIV-infected patients may still have an increased risk for cardiovascular morbidity and mortality, which might be related not only to traditional risks, but also to inflammation and dyslipidemia induced by HIV and/or antiretroviral therapy [1, 2]. We examined the relationship of serum lipid levels with plasma biomarkers of inflammation using a composite inflammatory burden score (IBS from the following seven markers of inflammation: CD40L, tPA, MCP-1, IL-8, IL-6, hCRP and P-selectin. Materials and Methods: Subjects were selected among consecutive HIV-infected males ≥18 years of age with an undetectable viral load (75th percentile were considered elevated and an IBS was constructed as the presence of zero, one, two, or three or more elevated biomarkers. Correlations between the IBS and lipid parameters were examined using Spearman's Rho and by ordered logistic regression proportional odds model to estimate the odds of more elevated (>75th percentile biomarkers. Results: 181 male patients were included into the study, the median age was 46.7 (Q1–Q3, 39.9–55.0 years and the median current CD4 cell count was 553.0 (Q1–Q3, 389–729 per microliter. The patients were mainly treated with two nucleoside reverse transcriptase inhibitor (NRTI plus one non-NRTI (NNRTI (N=100, 60.8% or two NRTI plus lopinavir (N=50, 27.6%. There was a significant correlation between the IBS and serum cholesterol (Rho=0.23, 95% CI, 0.09–0.37, triglycerides (Rho=0.30, 95% CI, 0.16–0.42 and cholesterol/HDL-cholesterol ratio (Rho=0.25, 95% CI 0.11–0.38. In the multivariable model a one unit increase in cholesterol/HDL-cholesterol ratio was associated with a 1.72-fold (95% CI, 1.27–2.33 increased odds of having a greater IBS. One unit increase (mmol/L of cholesterol and triglycerides was associated with a 1.41-fold (95% CI, 1.13–1.76 and 1.37-fold (95% CI, 1.18–1.60 increased odds of having a greater IBS, respectively

    We conducted a cross sectional study of the outpatient medical records of 1000 HIV-infected patients receiving antiretroviral therapy (ART) in 2011 to determine the incidence of clinically significant drug interactions (CSDI). The severities of the CSDI were graded following the Micromedex" 2.0 database and the Department of Health and Human Services (DHHS) 2012 HIV treatment guidelines. Three hundred thirty-five patients (34%) had 554 episodes of CSDI. Of which 337 episodes (61%), 163 episodes (29%) and 54 episodes (10%) had grades 2, 3 and 4 severity CSDI, respectively. The CSDI were caused by protease inhibitor (PI)-based drug regimens in 79%, by efavirenz-based regimens in 34% and by nevirapine-based regimens in 10% (pgemfibrozil (n=24) and didanosine with allopurinol (n=2). The three most common grade 3 CSDI were: a PI with a statin drug except simvastatin (n=56), fenofibrate with a statin drug (n=28) and amlodipine with simvastatin (n=14). On multivariate analysis, risk factors associated with CSDI were: receiving a PI-based regimen (OR 14.44; 95% CI: 9.10-22.88), having dyslipidemia (OR 3.94; 95% CI: 1.89-8.21), having >5 items prescribed at a time (OR 1.80; 95% CI: 1.23-2.63), seeing a doctor >4 times a year (OR 1.72; 95% CI: 1.20-2.46), having hypertension (OR 0.60; 95% CI: 0.37-0.98), having a duration of receiving ART of >5 years (OR 0.46; 95% CI: 0.28-0.77) and having a CD4 count of >200 cells/mm3 (OR 0.46; 95%CI: 0.26-0.84). CSDI were common among HIV-infected patients receiving ARV in our outpatient clinic. Patients having a low CD, count, having dyslipidemia, receiving PI-based ART, having a frequent number of visits per year and having a large number of items prescribed at each visit had a greater chance of a CSDI.

    Full Text Available Abstract Background Patients with HIV infection are at risk of co-infection with HBV, as the routes of transmission are shared and thus immunization with HBV vaccine could be protective in them. The aim of the present study was to assess the efficacy of recombinant vaccine in treatment-naive HIV positive patients and healthy controls, and to dissect out differences if any, in different limbs of immune response. Methods Forty HIV positive patients and 20 HIV negative controls, negative for HBsAg, HBsAbs and HBcAbs were vaccinated with three doses of 40μg and 20μg of vaccine respectively. Patients were divided into high CD4 and low CD4 group based on CD4+ lymphocytes of 200 and Results After vaccination, CD4+, CD8+ and CD3+ cells increased significantly in all the groups. There was no increase in NK cell activity in patients with high CD4+ lymphocytes and only a marginal increase in patients with low CD4+ lymphocytes (170 to 293/mm3 whereas a marked increase was observed in controls (252 to 490/mm3. After vaccination, although an increase in memory cells was observed in HIV positive patients, yet HBsAb levels were significantly lower than controls (P 4+ group: 8834 mIU/ml, low CD4+ group: 462 mIU/ml Vs. Controls: 16,906 mIU/ml. IL-4 and IL-10 were low in patients. Conclusion Despite a double dose in patients, IL-4 and IL-10, which regulate antibody response, were also lower in patients, and this together with low CD4+ counts and lack of T help, accounted for low HBsAb levels. Vaccination in patients with CD4+ lymphocytes 3 was ineffective. Thus early immunization is advocated in all HIV positive patients at a stage when they are still capable of mounting an adequate immune response

    Introduction HIV-induced changes in cytokine responses to bacteria may influence susceptibility to bacterial infections and the consequent inflammatory response. Methods We examined the impact of HIV on whole blood responsiveness to bacterial stimulation in asymptomatic subjects and patients with bacterial bloodstream infection (BSI). Whole blood was stimulated ex vivo with two bacterial Toll-like receptor agonists (lipopolysaccharide and lipoteichoic acid) and two pathogens (Streptococcus pneumoniae and non-typhoidal Salmonella), which are relevant in HIV-positive patients. Production of interferon-γ, tumour necrosis factor-α, interleukin-1β and interleukin-6 was used as a read-out. Results In asymptomatic subjects, HIV infection was associated with reduced interferon-γ, release after stimulation and priming of the pro-inflammatory cytokine response to non-typhoidal Salmonella. In patients with BSI, we found no such priming effect, nor was there evidence for more profound sepsis-induced immunosuppression in BSI patients with HIV co-infection. Conclusions These results suggest a complex effect of HIV on leukocyte responses to bacteria. However, in patients with sepsis, leukocyte responses were equally blunted in patients with and without HIV infection. PMID:27189532

    Full Text Available Purpose of the study Epidemiological studies have consistently demonstrated an inverse association between plasma HDL concentrations and cardiovascular risk. Although this cardioprotective role has been mainly attributed to its role in promoting cellular cholesterol efflux, there is an emerging interest in the anti-inflammatory and antioxidant properties of HDL. The aim of the study is to investigate the anti-inflammatory properties of HDL isolated from HIV-infected patients. Methods Cross-sectional study of 113 HIV-infected patients and 70 non-infected control subjects without evident CVD. From each subject, HDL was isolated by ultracentrifugation and its anti-inflammatory status was tested as its ability to inhibit MCP-1-induced migration of the monocytic cell line THP-1 using transwell cell culture chamber inserts with micropore filters of 5 microns pore size. HDL-associated proteins were measured by commercial ELISAs. Results Twenty-three HIV-infected patients were ART-naïve (32±15 years, 66.7% male and ninety were currently on ART (46±11 years, 78.9 % male. Most patients on ART (91.1% had undetectable viral load (<50 copies/mL. When compared to healthy subjects, both naïve and treated HIV-infected patients had lower plasma HDL-cholesterol levels (naïve: 45±12, ART: 50±10, controls: 55±10 mg/dL, p<0.05. HDL isolated from HIV naïve patients showed a significantly reduced anti-inflammatory activity (THP-1 monocyte migration capacity was 203% times higher in HIV patients than in control subjects. The anti-inflammatory activity of HDL from ART-treated HIV-infected patients was significantly improved when compared to naïve patients, although it remained significantly lower than controls (130% THP-1 monocyte migration vs controls. HDL from HIV-infected patients had a decreased concentration of the anti-inflammatory proteins Apo A1 (controls: 2.1±0.3, naïve: 1.4±0.2, ART: 1.6±0.1 mg/ml and LCAT (controls: 0.53±0.09, naïve: 0.34±0

    To characterise tissue sites of immune activation and HIV replication we performed FDG-PET in ART-treated and ART-naive HIV-infected individuals. Specific aims were to establish whether HIV-infected patients can be differentiated on the basis of the detection of specific locations of viral replication, even in the presence of an apparently optimal immunovirological response to ART, and whether these FDG-PET findings can be related to immunovirological variables and AIDS history status. Patients were divided into five groups as follows: subgroup A1 (full responders, n=8): current ART treatment, CD4+ T lymphocytes >500/mL, viral load <50 copies/mL; subgroup A2 (full responders, n=5): same criteria as A-1, but with a previous history of AIDS; subgroup A3 (immunological non responders, n=5): current ART treatment, viral load <50 copies/mL, low CD4+ T lymphocytes (<200/mL); group B (virological non responders, n = 2): current ART treatment, CD4+ T lymphocytes around 500/mL, viral load >50,000 copies/mL; group C (ART-naive, n=5): no current or previous ART treatment, increased viral load. PET images revealed different patterns of FDG uptake. All ART-treated patients with either suppressed (<50 copies/mL; Group A) or high viremia (group B) showed a normal pattern of FDG uptake. On the contrary, the ART-naive subjects with high viraemia (group C) displayed multiple foci of increased glucose metabolism in the lymph nodes. In the ART-naive subjects, FDG uptake, apparently related to viraemia level, was observed in the upper torso mainly in the axillary nodes bilaterally in patients with viraemia below 100,000 copies/mL; in those with viraemia higher than 100,000 copies/mL, FDG uptake was also observed in the inguinal lymph nodes. The emergence, in our study, of a correlation between the percentage of CD8+/CD38+/RO+ T cells (well established markers of progression to AIDS independently of CD4+ T lymphocytes) and positive FDG-PET in ART-naive patients is a novel finding that

    Full Text Available Background: Human herpes virus 8 (HHV-8, a gamma herpes virus, is the etiological agent for Kaposi sarcoma (KS. HIV-infected adults with advanced immunodeficiency are at risk. Prevalence data of HHV-8 infection in HIV-infected children living in non-endemic areas are limited. Serologic studies indicate low seroprevalence rates of 3–4% for healthy children living in United States and Germany [1]. Purpose of the study: The aim of the study was to determine the seroprevalence of HHV-8 antibodies among vertically HIV-infected pediatric patients in Germany and to evaluate their association with age, gender, ethnicity, and other demographic factors. Methods: In 2012, a multi-center cross-sectional study was conducted in four University Hospitals in Germany. Stored frozen serum specimens obtained from vertically HIV-infected children and adolescents were tested for antibodies against lytic and latent HHV-8 antigens. Data on patients' demographic characteristics and medical history were recorded. Results: A total of 214 HIV-infected children and adolescents (105 males, 109 females were included. The median age was 10.2 years (range 1 months–22.6 years. A high proportion of these children (62% was born in Western Europe, whereas 65% (139/214 of their mothers were born in countries outside Western Europe. The majoritiy (91% of the children had been treated with highly active antiretroviral therapy and 55.2% (116/210 had a HIV-viral load<50 copies/mL. The median CD4 cell count was 1000/L (range 3–4400. The overall seroprevalence of HHV-8 antibodies was 23.8% (51/214. Seroprevalence rates did not show significant differences between age or gender. In the group of young children aged 1 month to 35 months, 19.4% (46/31 had HHV-8 antibodies, compared to 25% (25/100 in children aged 36 months to 11 years, and 24.1% (20/83 children 12 years and older. In the study group, seroprevalence rates were significantly lower in children who were born in Western

  9. Low acute toxicity of radiotherapy and radiochemotherapy in patients with cancer of the anal canal and HIV-infection

    International Nuclear Information System (INIS)

    Although not an AIDS-defining malignancy, anal cancer is an evolving problem in HIV-infected patients. Treatment-tolerance to radiotherapy as well as to chemotherapy is supposed to be reduced in patients with HIV-infection. From January 1995 to January 1997, four patients with epidermoid cancer of the anal canal and a long history of HIV-infection but without symptoms of AIDS or repeated severe infections were treated with radiotherapy (n=1) or radiochemotherapy (n=3). External beam radiotherapy with 45 Gy to the tumor and pelvic as well as inguinal lymphatic drainage was administered. In tumors larger than T2 N0 lesions an additional boost of 9 Gy was given. Chemotherapy consisted of 5-fluorouracil 1000 mg/m2/24 h, d 1-4 two cycles and Mitomycin C either 1 x 15 mg/m2, d 1 in the first, or 2 x 10 mg/m2, d 1, in the first and fifth week of radiotherapy. Acute reactions were mild to moderate in all patients and all but one treatment could be given as scheduled (1 patient with a delay of 4 days). No excessive acute reactions were seen. Because of the short follow-up, late reactions and local control are not yet evaluable. (orig.)

    The role of neuronal surface autoantibodies (NSAs) in non-encephalitic psychosis is of recent and controversial interest. Most of the studies relating NSAs with psychosis are retrospective and only focused on the N-methyl-d-aspartate glutamate receptor (NMDAR). Our goal was to evaluate the prevalence of IgG antibodies against the NMDAR NR1 subunit (NMDAR-Abs) along with five additional NSAs in 61 first psychotic episode patients and 47 matched controls. We found two patients positive for NMDAR-Abs (3.3%). One of them was eventually considered to have been misdiagnosed and reclassified as encephalitis. The other met the criteria for bipolar I disorder, presented no neurological symptoms and had a comorbid HIV infection of vertical transmission. This is the first reported case of an HIV-infected patient with psychosis associated with NSAs. This study shows that patients presenting with clinically incomplete forms of anti-NMDAR encephalitis, with predominant or isolated psychiatric symptoms, can remain undetected if no ancillary tests are performed. To improve patient diagnosis and treatment of individuals with a first psychotic episode, more detailed neurological examinations might be needed. Further studies are required to better clarify the role of NSAs in the neuropsychiatric effects of HIV infection. PMID:26996305

    Full Text Available Introduction: Cryptococcal meningitis is one of the acquired immunodeficiency syndrome defining infections with high mortality. Amphotericin B is the preferred drug for induction therapy. Despite advances in human immunodeficiency virus (HIV treatment, Antiretroviral Treatment (ART roll-out programs and availability of amphotericin B, cryptococcal meningitis remains an important cause of mortality in the African and other developing countries. Materials and Methods: We carried out a prospective observational study to determine the treatment response rate, tolerability and outcome of patients with cryptococcal meningitis in HIV treated with amphotericin B. Descriptive statistic was used to analyze the data. Results: A total of 27 patients were diagnosed with cryptococcal meningitis during the study period. Headache (96.29% was the single most common presenting symptom of cryptococcal meningitis in HIV-infected patients, followed by vomiting (77.77% and fever (66.66%. Cerebrospinal fluid (CSF routine and microscopic examination was within normal limits in six patients. CSF became sterile on the 12th day of Amphotericin B in 55.55% of the patients while 33.33% had positive CSF cultures. Patients were started with ART after achieving sterile CSF and tolerated at least 2 weeks of fluconazole consolidation treatment and were free from symptoms. Median time for antiretroviral treatment initiation was 35 (14-90 days after completion of Amphotericin B treatment. One patient developed immune reconstitution inflammatory syndrome (IRIS after ART. Conclusions: We found that the recommended 2 weeks induction treatment with Amphotericin B monotherapy for HIV patients with cryptococcal meningitis in resource-limited settings may be suboptimal for at least one-third of the patients. Extending the therapy to 3 weeks is likely to result in sterilization of the CSF in a majority of these patients. This finding requires confirmation by a larger sample size in

    Neurocognitive (NC) complications continue to afflict a substantial proportion of HIV-infected people taking effective antiretroviral therapy (ART). One contributing mechanism for this is antiretroviral neurotoxicity. Efavirenz (EFV) is associated with short-term central nervous system (CNS) toxicity, but less is known about its long-term effects. Our objective was to compare NC functioning with long-term use of EFV to that of a comparator, lopinavir-ritonavir (LPV/r), in a cohort of well-characterized adults. Four hundred forty-five patients were selected from the CNS HIV Antiretroviral Therapy Effects Research (CHARTER) cohort based on their use of either EFV (n = 272, mean duration 17.9 months) or LPV/r (n = 173, mean duration 16.4 months) and the lack of severe NC comorbidities. All patients had undergone standardized comprehensive NC testing. Univariable and multivariable analyses to predict NC outcomes were performed. Compared with LPV/r users, EFV users were more likely to be taking their first ART regimen (p drugs may differ based on HCV coinfection. The complexity of these data is substantial, and findings would best be confirmed in a randomized clinical trial. PMID:26407716

  14. Patients with discordant responses to antiretroviral therapy have impaired killing of HIV-infected T cells.

    Directory of Open Access Journals (Sweden)

    Sekar Natesampillai

    Full Text Available In medicine, understanding the pathophysiologic basis of exceptional circumstances has led to an enhanced understanding of biology. We have studied the circumstance of HIV-infected patients in whom antiretroviral therapy results in immunologic benefit, despite virologic failure. In such patients, two protease mutations, I54V and V82A, occur more frequently. Expressing HIV protease containing these mutations resulted in less cell death, caspase activation, and nuclear fragmentation than wild type (WT HIV protease or HIV protease containing other mutations. The impaired induction of cell death was also associated with impaired cleavage of procaspase 8, a requisite event for HIV protease mediated cell death. Primary CD4 T cells expressing I54V or V82A protease underwent less cell death than with WT or other mutant proteases. Human T cells infected with HIV containing these mutations underwent less cell death and less Casp8p41 production than WT or HIV containing other protease mutations, despite similar degrees of viral replication. The reductions in cell death occurred both within infected cells, as well as in uninfected bystander cells. These data indicate that single point mutations within HIV protease which are selected in vivo can significantly impact the ability of HIV to kill CD4 T cells, while not impacting viral replication. Therefore, HIV protease regulates both HIV replication as well as HIV induced T cell depletion, the hallmark of HIV pathogenesis.

    Full Text Available Ukraine is a leader in Europe in the prevalence of HIV infection. There are up to 270 thousand people, who are living with HIV. Since 1987, in Ukraine, 33,149 HIV-infected people died. During the first six months of 2013, of all the dead, who were suffering from HIV and in need of antiretroviral treatment (ART at the time of death, 41% received treatment and only 5.7% received ART for more than one year. Specialists of Kiev Regional AIDS Center analyzed mortality among the patients of the centre, in order to determine the most frequent cause of death, set the group most at risk and to develop effective measures to reduce mortality among HIV-infected patients. In Kiev AIDS Center, 10,000 people are under medical observation and 4004 of them are taking ART. During 2013, 305 persons died: 217 were women and 88 were men which included 3 children under 14 years. Most of the dead – 272 (89% were aged 25–49. Among the total number of the dead, 125 people (41% were receiving ART, 53 of them (17% were receiving ART for at least one year and 39 of them (13% were receiving ART for less than one month. Hundred and fifty-eight people (52% required ART and 22 (7% did not need therapy. Hundred and ninety-two patients (63% were in four clinical stage of HIV infection. Hundred and ten of them had HIV+TB co-infection. Twenty patients died due to TB and 12 patients died due to hepatitis b virus/hepatitis c virus (HBV/HCV. Among these patients, 87 people (39% were taking ART and 136 persons (61% were in need of ART, but did not get it. Nineteen patients were diagnosed with cancer. Sixteen patients, who were co-infected HIV+TB had a CD4 cell count of more than 300. Based on this analysis, we can conclude that the main causes of high mortality among HIV-infected patients in 2013 were late diagnosis of HIV, besides a large number (52% of patients, who were in need of ART did not take it. A large number (40% among those who died were patients co-infected with HIV

    Full Text Available Aim and Objective: This study was carried out with the primary aim of correlating oral changes and general changes of HIV-infected patients with their CD4 count. Materials and Methods: 124 patients were selected, and after taking their informed consent, they were subjected to detailed history taking and thorough clinical examination. Specific oral lesions and general physical changes were recorded. Every patient was subjected to laboratory investigation for CD4 count. All these findings were tabulated. The clinical observation and laboratory findings were subjected to critical analysis and correlated. Statistical test, i.e. Student′s " t" test, was applied and objective conclusions were drawn. Result: Out of 124 patients, 40 had oral candidiasis, 6 had oral hairy leukoplakia, 12 had periodontal disease, 20 had xerostomia, 30 had melanin pigmentation, while 4 had HSV2, and atypical ulceration. Out of 40 patients with oral candidiasis, 28 patients had CD4 count 500 cell/mm 3 . Oral hairy leukoplakia occurred in equal proportions in group A and B. These periodontal diseases were more commonly in group B; xerostomia and melanin pigmentation was equally seen in group A and B. Conclusion: Oral candidiasis, oral hairy leukoplakia, linear gingival erythema, necrotizing ulcerative gingivitis, and necrotizing ulcerative periodontitis are specific oral indicators which will definitely suggest to the dental surgeon that the disease is running a rapid downhill course and due to this the oral physician is in a position to raise a suspicion and alert the general physician regarding the declining immune status of patient.

    Background Aging of persons with human immunodeficiency virus (HIV) resulted in high rates of osteopenia and osteoporosis. Multiple cohort studies have reported an increased prevalence of bone demineralization among HIV-infected individuals. The aim of this study was to evaluate bone mineral density (BMD) and risk factors for osteopenia/osteoporosis among HIV-positive patients attending the National Institute for Infectious Diseases “Prof.Dr. Matei Balș”, Bucharest, Romania. Methods We performed a cross-sectional study that enrolled 60 patients with HIV. The association between BMD and lifestyle habits (smoking), body mass index (BMI), nadir cluster of differentiation 4 (CD4) cell count, current CD4 cell count, HIV viral load and history of combination antiretroviral therapy (cART) were investigated. The BMD was measured at the lumbar spine, hips and total body using dual-energy X-ray absorptiometry (DEXA). Results In the present study, DEXA evaluation showed an overall prevalence of osteoporosis of 16.66% (ten patients) and a prevalence of osteopenia of 48.33% (29 patients). In men, low BMI and cigarette smoking showed significant association with the diagnosis of lumbar spine demineralization (p=0.034 and p=0.041, respectively). Duration of exposure to cART classes in relation to BMD was also evaluated. The use of non-nucleoside reverse-transcriptase inhibitors (NNRTIs) was associated with low lumbar spine BMD in all patients (p=0.015). Reduced BMD was significantly associated with protease inhibitors (PIs)-containing treatment (p=0.043) in women. Conclusion At lumbar spine DEXA, male gender was statistically associated with reduced BMD. At the left hip Ward’s area, decreased BMD T scores were significantly associated with aging. The reduced BMD was higher in patients receiving PI- or NNRTI-containing regimens.

    Full Text Available Abstract Background Active Cytomegalovirus (CMV infection is a common complication in advanced symptomatic Human Immunodeficiency Virus (HIV infection. CMV-induced intestinal perforations are hard to diagnose and may be observed throughout the gastrointestinal tract. Isolated stomach perforation is exceptional. Case presentation A 47-year-old man was admitted to our intensive care unit with multiorgan failure. Gastrointestinal endoscopic examination showed erythematous gastritis but normal duodenum and colon. CMV blood culture was positive. Histologic examination of a gastric biopsy showed inflammatory infiltrate and immunostaining typical intranuclear CMV inclusion bodies. Concomitant abdominal CT scan disclosed large peripancreatic hypodensities without pneumoperitoneum. The patient died despite supportive therapies and ganciclovir infusion. Postmortem examination showed a 4-cm gastric perforation adhering to the transverse colon and liver, with a thick necrotic inflammatory coating around the pancreas. The whole GI tract, except the stomach, was normal. As other causes, especially Helicobacter pylori infection could be ruled out, a causal relationship between CMV and gastric disease was assumed. Conclusion CMV may be responsible for gastric perforations, with difficulties in assessing the diagnosis. Early diagnosis based on cautious endoscopy and histopathologic examination is needed to make a favorable outcome possible.

    : Our aim was to explore the association among ACSM4 and PECI polymorphisms and AIDS progression in 454 HIV-infected patients never treated with antiretroviral drugs (146 long-term nonprogressors, 228 moderate progressors, and 80 rapid progressors). For ACSM4 polymorphisms, rs7137120 AA/AG and rs7961991 CC/CT genotypes had higher odds of having a rapid AIDS progression [odds ratio (OR) = 3.21; 95% of confidence interval (95% CI) = 1.26 to 8.16; P = 0.014 and OR = 3.60; 95% CI = 1.38 to 9.36; P = 0.009, respectively]. Additionally, the ACSM4 haplotype integrated for both rs7961991 A and rs7137120 C alleles had higher odds of having a rapid AIDS progression (OR = 2.85; 95% CI = 1.28 to 6.25; P = 0.010). For PECI polymorphisms, no significant associations were found. In conclusion, ACSM4 polymorphisms might play a significant role in AIDS progression. PMID:23982661

    Full Text Available Commencement of antiretroviral treatment (ART in severely immunosuppressed HIV-infected persons is associated with unmasking of subclinical disease. The subset of patients that are diagnosed with tuberculosis (TB disease while on ART have been classified as ART-associated TB. Few studies have reported the incidence of ART-associated TB and unmasking TB-IRIS according to the International Network for the Study of HIV-Associated IRIS (INSHI consensus definition. To determine the incidence and predictors of ART-associated TB, we screened 219 patients commencing ART at the Infectious Diseases Clinic in Kampala, Uganda for TB by symptoms, sputum microscopy, and chest X-rays and followed them for one year. Fourteen (6.4% patients were diagnosed with TB during followup. Eight (3.8% patients had ART-associated TB (incidence rate of 4.3 per 100 person years; of these, three patients fulfilled INSHI criteria for unmasking TB-associated IRIS (incidence rate of 1.6 per 100 person years. A body mass index of less than 18.5 kg/m2 BMI (HR 5.85 95% CI 1.24–27.46, P=.025 and a C-reactive protein greater than 5 mg/L (HR 8.23 95% CI 1.36–38.33, P=.020 were risk factors for ART-associated TB at multivariate analysis. In conclusion, with systematic TB screening (including culture and chest X-ray, the incidence of ART-associated TB is relatively low in settings with high HIV and TB prevalence.

    Full Text Available OBJECTIVE: To evaluate the prevalence of and the associated factors for metabolic syndrome (MS among Latin American HIV-infected patients receiving antiretroviral therapy (ART using baseline data from the RAPID II study. METHODS: A longitudinal study to evaluate the metabolic profile, cardiovascular disease (CVD risk and associated treatment practices to reduce this risk has been conducted in seven Latin American countries (the RAPID II study. Adult HIV patients with at least six months of RT were enrolled. MS was defined following ATP-III criteria. Demographic and anthropometric data, serum biochemical and clinical parameters were compared in patients with and without MS using bivariate and multivariate analysis. RESULTS: A total of 4,010 patients were enrolled, 2,963 (74% were males. Mean age (SD was 41.9 (10.0 years. The prevalence of MS was 20.2%. Females had higher prevalence of MS than males (22.7% vs. 19.4%, p = 0.02. MS was driven by high triglycerides, low HDL-cholesterol and high blood pressure (HBP. Patients with MS had higher 10year CVD risk: 22.2% vs. 7.4%, p < 0.001. Age (OR: 1.05 per year, female gender (OR: 1.29, family history of CVD (OR: 1.28, CD4 cell count (OR: 1.09 per 100 cell increase, and protease inhibitor based-ART (OR: 1.33 correlated with MS in the multivariate analysis. CONCLUSIONS: Prevalence of MS in this setting was similar to that reported from developed countries. MS was driven by high triglycerides, low-HDL and HBP, and it was associated with higher risk of CVD. Traditional risk factors, female gender, immune reconstitution, and protease inhibitor based-ART correlated with MS.

    Full Text Available As life expectancy improves among Human Immunodeficiency Virus (HIV patients, renal and cardiovascular diseases are increasingly prevalent in this population. Renal and cardiovascular disease are mutual risk factors and are characterized by albuminuria. Understanding the interactions between HIV, cardiovascular risk factors and renal disease is the first step in tackling this new therapeutic frontier in HIV.In a rural primary health care centre, 903 HIV-infected adult patients were randomly selected and data on HIV-infection and cardiovascular risk factors were collected. Glomerular filtration rate (eGFR was estimated. Albuminuria was defined as an Albumin-Creatinine-Ratio above 30 mg/g. Multivariate logistic regression analysis was used to analyse albuminuria and demographic, clinical and HIV-associated variables.The study population consisted of 903 HIV-infected patients, with a median age of 40 years (Inter-Quartile Range (IQR 34-48 years, and included 625 (69% women.

    Background Few data on the virological determinants of hepatitis B virus (HBV) infection are available from southern Africa. Methods We enrolled consecutive HIV-infected adult patients initiating antiretroviral therapy (ART) at two urban clinics in Zambia and four rural clinics in Northern Mozambique between May 2013 and August 2014. HBsAg screening was performed using the Determine® rapid test. Quantitative real-time PCR and HBV sequencing were performed in HBsAg-positive patients. Risk factors for HBV infection were evaluated using Chi-square and Mann-Whitney tests and associations between baseline characteristics and high level HBV replication explored in multivariable logistic regression. Results Seventy-eight of 1,032 participants in Mozambique (7.6%, 95% confidence interval [CI]: 6.1–9.3) and 90 of 797 in Zambia (11.3%, 95% CI: 9.3–13.4) were HBsAg-positive. HBsAg-positive individuals were less likely to be female compared to HBsAg-negative ones (52.3% vs. 66.1%, p20,000 UI/mL). HBsAg-positive individuals had higher levels of ALT and AST compared to HBsAg-negative ones (both p<0.001). In multivariable analyses, male sex (adjusted odds ratio: 2.59, 95% CI: 1.22–5.53) and CD4 cell count below 200/μl (2.58, 1.20–5.54) were associated with high HBV DNA. HBV genotypes A1 (58.8%) and E (38.2%) were most prevalent. Four patients had probable resistance to lamivudine and/or entecavir.

  16. Increased lung epithelial permeability in HIV-infected patients with isolated cytotoxic T-lymphocytic alveolitis

    International Nuclear Information System (INIS)

    HIV-related lymphocytic alveolitis is common in HIV-seropositive patients without lung infection or tumor. In some of them a fraction of alveolar lymphocytes are HIV-specific cytotoxic T-lymphocytes (CTL) bearing the CD8 and D44 cell surface markers and capable of killing HIV-infected alveolar macrophages. In order to evaluate the in vivo effect of these CTL on lung function, we measured the pulmonary clearance of aerosolized 99mTc-diethylene triamine penta-acetate (DTPA-CI) on 24 occasions in 22 patients with lymphocytic alveolitis. DTPA-CI has been selected as a highly sensitive test to detect injury of the lung epithelium. In 13 of the patients, we found a high DTPA-CI of 4.56 +/- 2.54%.min-1 (mean +/- SD), suggesting an increase of the epithelial permeability. The lymphocytic alveolitis was then characterized by a high cellularity, a high proportion of lymphocytes (59 +/- 18%), mainly composed of CD8+D44+ T-lymphocytes (149 +/- 109 cells/mm3), which spontaneously exhibited a cytolytic activity against the autologous alveolar macrophages in a standard 51Cr release assay. In the remaining 11 patients, DTPA-CI was normal (less than 1.78%.min-1), lymphocytic alveolitis being characterized by a low number or an absence of CD8+D44+ alveolar lymphocytes (9 +/- 13 cells/mm3) with no significant cytolytic activity. In the whole group, a significant correlation (r = 0.74, p = 0.0004) was found between the DTPA-CI and the number of CD8+D44+ lymphocytes and their cytotoxic activity against alveolar macrophages. Altogether, these results suggest that an injury of the lung epithelium could result from a HIV-specific CTL-induced immunologic conflict

    Full Text Available SUMMARY Introduction: We present a fatal case of disseminated cryptococcosis in a young man whose diagnosis of HIV infection was made at the time of admission to the emergency room. Case report: The patient was a twenty-three-year-old man, with a history of daily fever during one month associated with diarrhea, weight loss, headache, vomiting and generalized seizures. He also had a history of diabetes mellitus, alcoholism and drug addiction. Upon physical examination the patient was pale, disoriented and had periods of agitation. White blood cells count was 3,440/mm3 (5% lymphocytes, hemoglobin was 10g/dL, platelets were 83,000/ mm3. Creatinine was 0.7 mg/dL; urea 19 mg/dL; Na, K, and liver enzymes were within normal limits. Lactic dehydrogenase was 494 IU/L. Cerebrospinal fluid (CSF analysis revealed 10 white blood cells/mm3 (58% neutrophils, 31% lymphocytes, 11% monocytes and 2 red blood cells/mm3. India ink test revealed six Cryptococcus yeasts/mm3. CSF glucose was 122 mg/dL and protein was 36 mg/ dL. VDRL test was negative and anti-HIV test was positive. Intravenous hydration, insulin, phenytoin, fluconazole, pyrimethamine, sulfadiazine, folinic acid, and amphotericin B were started. The patient did not improve and became obtunded and hypotensive. He was intubated and put on mechanical respiration. He received vasoactive drugs and died less than 24 hours after admission. A postmortem examination was performed and revealed disseminated cryptococcosis, with severe involvement of the kidneys. Conclusion: Cryptococcosis, as a rule, is a systemic disease that affects mostly immunocompromised individuals, especially patients with AIDS. When diagnosed late in its course it has a very high mortality.

    Full Text Available Abstract Background Our objective was to evaluate and compare the effect of abacavir on levels of biomarkers associated with cardiovascular risk. Methods In an open-label randomized trial, HIV-infected patients were randomized 1:1 to switch from zidovudine/lamivudine to abacavir/lamivudine or tenofovir/emtricitabine. In the present analysis, we measured levels of interleukin-6 (IL-6, high-sensitivity C-reactive protein (hs-CRP, soluble intercellular adhesion molecule-1 (sICAM-1, soluble vascular adhesion molecule-1 (sVCAM-1, E-selectin, and myeloperoxidase (MPO at baseline and 4, 12, and 48 weeks after randomization. D-dimer and fasting lipids were measured at baseline and weeks 12 and 48. Levels of biomarkers at all time points and changes from baseline were compared across study arms using Wilcoxon rank sum test. Results Of 40 included patients, 35 completed 48 weeks of randomized therapy and follow up. Levels of E-selectin (P = 0.004 and sVCAM-1 (P = 0.041 increased transiently from baseline to week 4 in the abacavir arm compared with the tenofovir arm, but no long-term increases were detected. We found no significant differences between study arms in the levels or changes in the levels of sICAM-1, MPO, d-dimer, IL-6, or hs-CRP. Levels of total cholesterol and high density lipoprotein (HDL increased in the abacavir arm relative to the tenofovir arm, but no difference was found in total cholesterol/HDL ratio. Conclusion In patients randomized to abacavir-based HIV-treatment transient increases were seen in the plasma levels of E-selectin and sVCAM-1 compared with treatment with tenofovir, but no difference between study arms was found in other biomarkers associated with endothelial dysfunction, inflammation, or coagulation. The clinical significance of these findings is uncertain. Trial Regestration Clinicaltrials.gov identifier: NCT00647244.

    The primary way of preventing HIV infections is to change behaviors that enable transmission of the virus, specifically those behaviors relating to sex and drug injection. Realistic public health workers have focused on encouraging adoption of safer sexual practices, primarily condom use. The fundamental way to persuade people to engage in preventive practices is through targeted education aimed at particularly at-risk communities. Other effective behavioral interventions against HIV infections are: testing and follow-up counseling; comprehensive sex education; peer influence and community action; advertising and marketing; easing access to condoms; physician-patient dialogue; drug treatment; access to clean needles; and direct outreach. On the contrary, interventions that do not work are the following: one-time exposure to information; delivering a single message; abstinence-only programs; and coercive measures to identify people with HIV or their sexual partners.

    agents and/or drugs. Little is known about the prevalence of renal diseases that may occur as a complication of or related to HIV infection in asymptomatic patients. This is a single center cross-sectional study of asymptomatic HIV+ patients referred to a nefrology care service at an Argentine hospital to look for the presence of renal abnormalities. Fifty two consecutive patients were studied between April and November 2008. Patients underwent plasma and urine analysis, ultrasound, and kidney biopsy as needed. Mean age was 39.9 ± 10.6 years, 88% were male, time from HIV diagnosis 53.2 ± 41.2 months (2-127; 71% had HIV-disease and 77% were on antiretroviral therapy. Mean plasma HIV-RNA copies number was 7.043 ± 3.322 and CD4+ cell count: 484 ± 39. Pathologic findings in urine analysis were present in 30.7% of patients: albuminuria 16.6%, microscopic hematuria 11.5%, hypercalciuria 10.8% and crystalluria 6%. Mean glomerular filtration rate was 102.2 ± 22.95 ml/min (34-149 and 41% of patients could be classified in stages 1 to 3 of chronic kidney disease. Renal abnormalities prevaled in older patients without relationship with presence of HIV-disease. Two patients were biopsied and the findings included: tubulointerstitial nephritis with presence of crystal deposition in one and IgA nephropathy in the other. No HIV-associated nephropathy was detected. The broad spectrum and the high prevalence of lesions found in this series suggest that asymptomatic HIV-infected patients should routinely undergo renal evaluation.

    Full Text Available Background and objective: There are no recent data on the prevalence of drug-resistant tuberculosis (DR TB in Cambodia. We aim to describe TB drug resistance amongst adults with pulmonary and extra-pulmonary TB and human immunodeficiency virus (HIV co-infection in a national referral hospital in Phnom Penh, Cambodia. Design: Between 22 November 2007 and 30 November 2009, clinical specimens from HIV-infected patients suspected of having TB underwent routine microscopy, Mycobacterium tuberculosis culture, and drug susceptibility testing. Laboratory and clinical data were collected for patients with positive M. tuberculosis cultures. Results: M. tuberculosis was cultured from 236 HIV-infected patients. Resistance to any first-line TB drug occurred in 34.7% of patients; 8.1% had multidrug resistant tuberculosis (MDR TB. The proportion of MDR TB amongst new patients and previously treated patients was 3.7 and 28.9%, respectively (p<0.001. The diagnosis of MDR TB was made after death in 15.8% of patients; in total 26.3% of patients with MDR TB died. The diagnosis of TB was established by culture of extra-pulmonary specimens in 23.6% of cases. Conclusions: There is significant resistance to first-line TB drugs amongst new and previously treated TB–HIV co-infected patients in Phnom Penh. These data suggest that the prevalence of DR TB in Cambodia may be higher than previously recognised, particularly amongst HIV-infected patients. Additional prevalence studies are needed. This study also illustrates the feasibility and utility of analysis of non-respiratory specimens in the diagnosis of TB, even in low-resource settings, and suggests that extra-pulmonary specimens should be included in TB diagnostic algorithms.

    Albuminuria among HIV-infected individuals has been found to be associated with cardiovascular disease (CVD) and mortality. Inflammation has been associated with albuminuria. The pathophysiology of albuminuria in HIV-infected individuals is poorly understood. We investigated the association of albuminuria with inflammatory biomarkers among HIV-infected individuals on combination antiretroviral therapy (cART). This is a cross-sectional analysis of participants enrolled in the Hawaii Aging with HIV-Cardiovascular Cohort. Plasma inflammatory biomarkers were assessed using the Milliplex Human Cardiovascular disease multiplex assays. A random urine sample was collected for albumin measurement. Albuminuria was defined as urine albumin-to-creatinine ratio of ≥30 mg/g. Framingham risk score was calculated and divided into three classes. Simple and multivariable logistic regression analyses were utilized to assess the correlation between plasma inflammatory biomarkers and albuminuria and were adjusted for Framingham risk category. Among 111 HIV-infected patients [median (IQR) age of 52 (46-57) years, 86% male, median (IQR) CD4 count of 489 (341-638) cells/mm(3), 85% with HIV RNA CVD risk factors. This study showed an association between inflammation and albuminuria independent of previously reported risk factors for albuminuria in HIV-infected subjects who were on combination antiretroviral therapy (cART). Chronic inflammation despite potent antiretroviral treatment may contribute to higher rates of albuminuria among HIV-infected patients. PMID:25205472

    AIM: To analyze the molecular evolution of different viral genomic regions of HCV in an acute HCV infected patient chronically infected with HIV through a 42-month follow-up.METHODS: Serum samples of a chronically HIV infected patient that seroconverted to anti HCV antibodies were sequenced, from the event of superinfection through a period of 17 months and in a late sample (42nd month). Hypervariable genomic regions of HIV (V3 loop of the gp120) and HCV (HVR-1 on the E2 glycoprotein gene) were studied. In order to analyze genomic regions involved in different biological functions and with the cellular immune response, HCV core and NS5A were also chosen to be sequenced. Amplification of the different regions was done by RT-PCR and directly sequenced. Confirmation of sequences was done on reamplified material. Nucleotide sequences of the different time points were aligned with CLUSTAL W 1.5, and the corresponding amino acid ones were deduced.RESULTS: Hypervariable genomic regions of both viruses (HVR1 and gp120 V3 loop) presented several nonsynonymous changes but, while in the gp120 V3 loop mutations were detected in the sample obtained right after HCV superinfection and maintained throughout, they occurred following a sequential and cumulative pattern in the HVR1. In the NS5A region of HCV, two amino acid changes were detected during the follow-up period, whereas the core region presented several amino acid replacements, once the HCV chronic infection had been established.CONCLUSION: During the HIV-HCV superinfection, each genomic region analyzed shows a different evolutionary pattem.Most of the nucleotide substitutions observed are nonsynonymous and clustered in previously described epitopes,thus suggesting an immune-driven evolutionary process.

    Full Text Available Introduction: Switching brand name medications to generics is recommended in France in the interest of cost effectiveness but patients and physicians are sometimes not convinced that switching is appropriate. Some antiretroviral (ARV generics (ZDV, 3TC, NVP have been marketed in France since 2013. Materials and Methods: A multicentric cross-sectional survey was performed in September 2013 to evaluate the perception of generics overall and ARV generics in physicians and HIV-infected patients and factors associated to their acceptability. Adult HIV outpatients were asked to complete a self-questionnaire on their perception of generics. Physicians completed a questionnaire on the acceptability of generics and ARV generics. Socio-demographic data, medical history and HIV history were collected. Results: 116 physicians in 33 clinics (68% in University Hospital included 556 patients (France-native 77%, active employment 59%, covered by social Insurance 100%, homosexual/bisexual contamination 47%, median HIV duration 13 years, hepatitis coinfection 16%, on ARV therapy 95%. Overall, patients accepted and had confidence in generics in 76% and 55% of the cases, respectively. Switching ARVs for generics was accepted by 44% of the patients but only by 17% if the pill burden was going to increase. 75% of the physicians would prescribe generics, but this decreased to only 26% if the combo had to be broken. The main reasons for non-prescription of generics were previous brand name ARV-induced side effects (35%, refusal of generics overall (37%, lack of understanding of generics (26%, risk of non-observance of treatment (44%, anxiety (47% and depressive symptoms (25%. In multivariate analysis, factors associated with the acceptability of ARV generics in patients were the use of generics overall (p<0.001 and in physicians, the absence of concern regarding the drug efficacy (p<0.001 and being aware that the patient would accept generics overall (p=0.03 and ARV

    HIV testing constitutes an important strategy to control the HIV epidemic, which therefore merits an observation of HIV testing practices to help improve testing effectiveness. In 2008, a cross-sectional survey among recently diagnosed (≤ 3 years) HIV-infected patients was conducted in Belgium, Estonia, Finland and Portugal. Participants were questioned about reasons for HIV testing, testing place and testing conditions. Univariate and multivariate analyses were performed. Out of 1460 eligible participants, 629 (43%) were included. Forty-one per cent were diagnosed late and 55% had never undergone a previous HIV test with perceived low risk being the primary reason for not having been tested earlier. Heterogeneity in HIV testing practices was observed across countries. Overall, tests were most frequently conducted in primary care (38%) and specialised clinics (21%), primarily on the initiative of the health care provider (65%). Sixty-one per cent were tested with informed consent, 31% received pretest counselling, 78% received post-test counselling, 71% were involved in partner notification and 92% were in care three months after diagnosis. The results showed that HIV testing is done in a variety of settings suggesting that multiple pathways to HIV testing are provided. HIV testing practice is being normalised, with less focus on pretest counselling, yet with emphasis on post-test follow-up. Major barriers to testing are centred on the denial of risk. Efforts are needed to concurrently promote public awareness about HIV risk and benefits of HIV testing and train clinicians to be more proactive in offering HIV testing. PMID:24090396

DESIGN: Cross-sectional cohort study. METHODS: Consecutive HIV-infected adults (≥ 18y/o initiating HIV care were enrolled from May 2007-May 2008, regardless of signs or symptoms of active TB. Prior TB history and current TB treatment status were self-reported. Subjects expectorated sputum for culture (MGIT liquid and 7H11 solid medium. Positive cultures were tested for susceptibility to first- and second-line anti-tuberculous drugs. The prevalence of drug-resistant TB, stratified by prior TB history and current TB treatment status, was assessed. RESULTS: 1,035 subjects had complete culture results. Median CD4 count was 92/µl (IQR 42-150/µl. 267 subjects (26% reported a prior history of TB and 210 (20% were receiving TB treatment at enrollment; 191 (18% subjects had positive sputum cultures, among whom the estimated prevalence of resistance to any antituberculous drug was 7.4% (95% CI 4.0-12.4. Among those with prior TB, the prevalence of resistance was 15.4% (95% CI 5.9-30.5 compared to 5.2% (95% CI 2.1-8.9 among those with no prior TB. 5.1% (95% CI 2.4-9.5 had rifampin or rifampin plus INH resistance. CONCLUSIONS: The prevalence of TB resistance to at least one drug was 7.4% among adults with positive TB cultures initiating ART in Durban, South Africa, with 5.1% having rifampin or rifampin plus INH resistance. Improved tools for diagnosing TB and drug resistance are urgently needed in areas of high HIV/TB prevalence.

    Full Text Available Introduction: Late HIV diagnosis is common and associated with an increased risk of clinical progression, blunted immune response on antiretroviral (ARV therapy and higher risk of drug toxicity. Across Europe, more than a third of patients are diagnosed late and consequently delay medical care.

    Monitoring of humans either in the healthy men under extreme environmental stress like space flight, in human immunodeficiency virus (HIV) infected patients or in sepsis is of critical importance with regard to the timing of adequate therapeutic (counter-)measures. The in vivo skin delayed-type hypersensitivity test (DTH) served for many years as a tool to evaluate cell mediated immunity. However, this standardised in vivo test was removed from the market in 2002 due to the risk of antigen stabilization. To the best of our knowledge an alternative test as monitoring tool to determine cell mediated immunity is not available so far. For this purpose we tested a new alternative assay using elements of the skin DTH which is based on an ex vivo cytokine release from whole blood and asked if it is suitable and applicable to monitor immune changes in HIV infected patients and in patients with septic shock.

  5. Antiretroviral-Related Adipocyte Dysfunction and Lipodystrophy in HIV-Infected Patients: Alteration of the PPARγ-Dependent Pathways

    Directory of Open Access Journals (Sweden)

    Martine Caron

    2009-01-01

    Full Text Available Lipodystrophy and metabolic alterations are major complications of antiretroviral therapy in HIV-infected patients. In vitro studies using cultured murine and human adipocytes revealed that some protease inhibitors (PIs and nucleoside reverse transcriptase inhibitors (NRTIs were implicated to a different extent in adipose cell dysfunction and that a chronic incubation with some PIs decreased mRNA and protein expression of PPARγ. Defective lamin A maturation linked to PI inhibitory activity could impede the nuclear translocation of SREBP1c, therefore, reducing PPARγ expression. Adipose cell function was partially restored by the PPARγ agonists, thiazolidinediones. Adverse effects of PIs and NRTIs have also been reported in macrophages, a cell type that coexists with, and modulates, adipocyte function in fat tissue. In HIV-infected patients under ART, a decreased expression of PPARγ and of PPARγ-related genes was observed in adipose tissue, these anomalies being more severe in patients with ART-induced lipoatrophy. Altered PPARγ expression was reversed in patients stopping PIs. Treatment of patients with agonists of PPARγ could improve, at least partially, the subcutaneous lipoatrophy. These data indicate that decreased PPARγ expression and PPARγ-related function, resulting from ART-induced adipose tissue toxicity, play a central role in HIV-related lipoatrophy and metabolic consequences.

    Individuals with HIV infection are living substantially longer on antiretroviral therapy, but hospitalization rates continue to be relatively high. We do not know how overall or diagnosis-specific hospitalization rates compare between HIV-infected and uninfected individuals or what conditions may drive hospitalization trends. Hospitalization rates among United States Veterans were calculated and stratified by HIV serostatus and principal diagnosis disease category. Because alcohol-related diagnoses (ARD) appeared to have a disproportional effect, we further stratified our calculations by ARD history. A multivariable Cox proportional hazards model was fitted to assess the relative risk of hospitalization controlling for demographic and other comorbidity variables. From 1997 to 2011, 46,428 HIV-infected and 93,997 uninfected patients were followed for 1,497,536 person-years. Overall hospitalization rates decreased among HIV-infected and uninfected patients. However, cardiovascular and renal insufficiency admissions increased for all groups while gastrointestinal and liver, endocrine, neurologic, and non-AIDS cancer admissions increased among those with an alcohol-related diagnosis. After multivariable adjustment, HIV-infected individuals with an ARD had the highest risk of hospitalization (hazard ratio 3.24, 95 % CI 3.00, 3.49) compared to those free of HIV infection and without an ARD. Still, HIV alone also conferred increased risk (HR 2.08, 95 % CI 2.04, 2.13). While decreasing overall, risk of all-cause hospitalization remains higher among HIV-infected than uninfected individuals and is strongly influenced by the presence of an ARD. PMID:25711299

    Full Text Available OBJECTIVES: To determine whether for a given waist circumference (WC, a larger hip circumference (HC was associated with a reduced risk of insulin resistance, type 2 diabetes (T2D, hypertension and cardiovascular disease (CVD in HIV-infected patients. A second objective was to determine whether, for a given WC, the addition of HC improved upon estimates of abdominal adiposity, in particular visceral adipose tissue (VAT, compared to those obtained by WC alone. METHODS: HIV-infected men (N = 1481 and women (N = 841 were recruited between 2005 and 2009. WC and HC were obtained using standard techniques and abdominal adiposity was measured using computed tomography. RESULTS: After control for WC and covariates, HC was negatively associated with risk of insulin resistance (p<0.05 and T2D [Men: OR = 0.91 (95% CI: 0.86-0.96; Women: OR = 0.91 (95% CI: 0.84-0.98]. For a given WC, HC was also negatively associated with a lower risk of hypertension (p<0.05 and CVD [OR = 0.94 (95% CI: 0.88-0.99] in men, but not women. Although HC was negatively associated with VAT in men and women after control for WC (p<0.05, the addition of HC did not substantially improve upon the prediction of VAT compared to WC alone. CONCLUSIONS: The identification of HIV-infected individuals at increased health risk by WC alone is substantially improved by the addition of HC. Estimates of visceral adipose tissue by WC are not substantially improved by the addition of HC and thus variation in visceral adiposity may not be the conduit by which HC identifies increased health risk.

  10. Excess apoptosis of mononuclear cells contributes to the depressed cytomegalovirus-specific immunity in HIV-infected patients on HAART

    International Nuclear Information System (INIS)

    HIV-infected patients on highly active antiretroviral therapy (HAART) have persistently decreased cytomegalovirus (CMV)-specific proliferative responses [lymphocyte proliferation assay (LPA)] in spite of increases in CD4+ T cell counts. Here we demonstrate an association between apoptosis of unstimulated peripheral blood mononuclear cells (uPBMC) and decreased CMV-LPA. HAART recipients had more apoptosis of uPBMC than controls when measured by caspases 3, 8, and 9 activities and by annexin V binding. Patients with undetectable HIV replication maintained significantly higher apoptosis of CD4+ and CD14+ cells compared to controls. CMV-LPA decreased with higher apoptosis of uPBMC in patients only. This association was independent of CD4+ cell counts or HIV replication. Furthermore, rescuing PBMC from apoptosis with crmA, but not with TRAIL- or Fas-pathway blocking agents or with other caspase inhibitors, increased CMV-LPA in HAART recipients. This effect was not observed in uninfected controls, further indicating that the down regulatory effect of apoptosis on cell-mediated immunity (CMI) was specifically associated with the HIV-infected status

    Full Text Available BK virus (BKV and JC virus (JCV persist as latent infection in the kidneys. Reactivation of both viruses may be linked to immunodeficiency. The aims of this study were to determine the prevalence of BKV and JCV viruria and to evaluate the relationship between immunodeficiency and viruria in a cohort of HIV-infected patients. Urine samples from 93 HIV-infected patients were collected and tested for the presence of BKV and JCV DNA by PCR. The overall prevalence of polyomavirus DNA in urine was 74.2%. BKV DNA was detected in 30.1% urine samples and JCV DNA in 23.7% samples. Both BKV and JCV DNA were detected in 20.4% samples. There was no association between BKV/JCV urinary shedding and the degree of immunosuppression measured by CD4+ cell count. However, taking into account the severity of disease resulting from reactivation of BKV and JCV, patients with HIV/polyomavirus co-infection should be kept under frequent and regular supervision.

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

    International Nuclear Information System (INIS)

    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

    Full Text Available Abstract Background Immune reconstitution inflammatory syndrome (IRIS is an important complication of HAART in sub-Saharan Africa, where opportunistic infections (OIs including mycobacteria and cryptococcus are common. The immune system's role in HIV infected patients is complex with cytokine expression strongly influencing HIV infection and replication. Methods We determined the expression patterns of 10 cytokines by Luminex multi-analyte profiling in 17 IRIS nested case-control pairs participating in a prospective South African cohort initiating anti-retroviral therapy. Results Interferon-gamma (IFN-γ expression was significantly elevated in IRIS cases compared to controls (median 9.88 pg/ml versus 2.68 pg/ml, respectively, P = 0.0057, while other cytokines displayed non-significant differences in expression. Significant correlation was observed between IL-6, IL-10, and IFN-γ expression in the IRIS patients. Conclusions Significantly increased expression levels of IFN-γ suggest that this cytokine possibly plays a role in IRIS pathology and is a potential diagnostic marker.

    Directory of Open Access Journals (Sweden)

    Daisuke Mizushima

    Full Text Available OBJECTIVE: The 2010 WHO antiretroviral therapy (ART guidelines have resulted in increased tenofovir use. Little is known about tenofovir-induced chronic kidney disease (CKD in HIV-infected Vietnamese with mean body weight of 55 kg. We evaluated the prevalence and risk factors of CKD in this country. DESIGN: Cross-sectional study was performed. METHODS: Clinical data on HIV-infected Vietnamese cohort were collected twice a year. To evaluate the prevalence of CKD, serum creatinine was measured in 771 patients in October 2011 and April 2012. CKD was defined as creatinine clearance less than 60 ml/min at both time points. Multivariate logistic regression was used to determine the factors associated with CKD. RESULTS: Tenofovir use increased in Vietnam from 11.9% in April 2011 to 40.3% in April 2012. CKD was diagnosed in 7.3%, of which 7% was considered moderate and 0.3% was severe. Multivariate analysis of October-2011 data identified age per year-increase (OR: 1.229, 95%CI, 1.170-1.291, body weight per 1 kg-decrement (1.286, 1.193-1.386, and tenofovir use (2.715, 1.028-7.168 as risk factors for CKD. CONCLUSIONS: Older age, low body weight and tenofovir use were independent risk factors for CKD in Vietnam. Further longitudinal study is required to evaluate the impact of TDF on renal function in Vietnam and other countries with small-body weight patients.

  17. Chemotherapy and low-dose radiotherapy in the treatment of HIV-infected patients with carcinoma of the anal canal

    International Nuclear Information System (INIS)

    Purpose: To determine the efficacy and tolerance of a standardized protocol of chemotherapy and low-dose radiotherapy in the treatment of anal cancer in human immunodeficiency virus (HIV)-infected patients. Methods and Materials: Between 1987 and 1995, eight HIV-positive patients with squamous cell carcinoma of the anal canal, four of whom had acquired immunodeficiency syndrome (AIDS), received therapy at the Kaiser Permanente Medical Center. All patients were treated using a combined modality approach consisting of lowdose radiotherapy (30 Gy in 15 fractions delivered 5 days/week), and chemotherapy [1000 mg/m2 of 5-fluorouracil (5-FU) delivered on days 1-4 and 29-32 as a continuous infusion over 96 h, and 10 mg/m2 of mitomycin C delivered as a bolus injection on day 1]. Patients have been followed from 4 to 81 months (mean 41, median 38). Results: All eight patients completed the therapy with minor variations to the protocol, and all have attained a clinical complete response. Four patients are alive and free of disease, and four died as a result of complications of AIDS, but remained free of anal carcinoma. There were no mortalities from the protocol and the morbidity was acceptable. Only one patient each was noted to have Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer Grade 4 hematologic and gastrointestinal acute toxicity, and no Grade 4 skin toxicity was noted. Conclusion: This combined therapy is effective for HIV-infected patients and appears to be tolerable with acceptable toxicities. It is best applied to patients who are HIV positive, or who have AIDS without concurrent major opportunistic infections. This approach is reasonable and affords patients a reasonably good chance at sphincter preservation by avoiding abdominoperineal resection. The optimal therapy for HIV-positive patients with advanced AIDS remains less well defined

This article sets out the differential aspects in the clinical manifestations of TB amongst populations with and without HIV infection; we also comment on some special characteristics in the treatment of tuberculosis in HIV patients. With the exception of primary cutaneous infections produced by accidental inoculation and infantile lymphadenitis, the majority of the cases of disease due to non-tuberculosis mycobacteria (NTM affect patients with certain predisposing factors. In the case of patients with AIDS, the deep immunological disorder provoked by HIV brings a particular susceptibility to suffering invasive disease due to certain NTM, principally M. avium complex and M. kansasii.

    Although hepatitis B virus (HBV) and human immunodeficiency virus (HIV) co-infection is common, only few data are available on HBV among HIV patients including occult hepatitis B infection (OBI), regardless of serological markers. This study aims to determine the prevalence of OBI and overall HBV infection, associated factors, HBV genotypes, and surface (S) gene mutations in a population of treatment-naïve HIV-infected patients in Brazil. A cross-sectional study was conducted in treatment-naïve HIV-infected patients in Central Brazil. All samples were tested for HBV serological markers and HBV DNA. Sequence analysis of the S gene and overlapping polymerase gene was preformed. Overall, 25.1% (127/505) of the patients had markers of current or previous HBV infection, which was associated with age over 40 years, history of injection drug use, and homosexual sex. The hepatitis B surface antigen (HBsAg) seroprevalence was 4.9% (25/505). HBV DNA was detected in 39 out of 505 patients: 20 of them were HBsAg-positive and 19 were HBsAg-negative, resulting in an OBI prevalence of 3.8%. Patients with OBI had significantly higher HCV seropositivity rate compared to HBsAg-positive patients. Sequencing of the S gene revealed Y100C, T131N, and D144A mutations. One patient had the M204I and L180M drug-resistance mutations (polymerase). HBV genotypes A (A1, A2), D (D2, D3), and F (F2) were identified. In conclusion, OBI represented almost half of all HBV infections with detectable HBV DNA, suggesting that hepatitis B diagnosis in HIV patients should include in addition to serological markers the detection of HBV DNA.

    Full Text Available Introduction: Inversion of the CD4:CD8 ratio (<1 has been identified as a hallmark of immunosenescence and an independent predictor of mortality in the general population. We aimed to assess the association between the CD4:CD8 ratio and intima-media thickness (IMT progression in treated HIV-infected patients as a marker of early atherosclerosis. Materials and Methods: A longitudinal study during three years was conducted in 120 HIV-infected patients receiving antiretroviral treatment (ART. We analyzed the associations between the CD4:CD8 ratio, cardiovascular risk factor and antiretroviral (ARV treatment and progression of subclinical atherosclerosis assessed using carotid IMT at baseline and after three years. Results: Finally, 96 patients completed the study. Seventy-six (79.1% patients were male, aged 44±10 years, 39 (40.6% were on treatment with Protease inhibitors, 49 (51.04% with non-nucleoside reverse transcriptase inhibitors (NNRTI, 6 (6.25% with integrase inhibitors, 3 (3.12% with maraviroc and 2 (2.08% only with nucleoside reverse transcriptase inhibitors (NRTI.

    Full Text Available Introduction: Doravirine (DOR is an investigational NNRTI (aka MK-1439 that retains activity against common NNRTI-resistant mutants. We have previously reported the Part 1 results from a two-part, randomized, double-blind, Phase IIb study in ART-naïve HIV-1-positive patients (1. At doses of 25, 50, 100 and 200 mg qd, DOR plus open-label tenofovir/emtricitabine (TDF/FTC demonstrated potent antiretroviral activity comparable to EFV 600 mg qhs plus TDF/FTC and was generally well tolerated at week 24. DOR 100 mg was selected for use in patients continuing in Part 1 and those newly enrolled in Part 2. Methods: Patients receiving DOR 25, 50 or 200 mg in Part 1 were switched to 100 mg after dose selection. In Part 2, 132 additional patients were randomized 1:1 to DOR 100 mg qd or EFV 600 mg qhs (each with TDF/FTC. We present week 48 efficacy and safety results for all patients in Part 1, and early (week 8 CNS tolerability only for patients randomized to DOR 100 mg or to EFV in Parts 1 and 2 combined. The primary safety endpoint is the % of patients with pre-specified CNS events (all causality by week 8 for DOR 100 mg qd vs EFV (Parts 1 + 2 combined. Results: Part 1 week 48 efficacy and safety results are shown below. The most common DR clinical AEs in the DOR and EFV groups, respectively, were abnormal dreams (10.2%; 9.5%, nausea (7.8%; 2.4%, fatigue (7.2%; 4.8%, diarrhoea (4.8%; 9.5% and dizziness (3.0%; 23.8%, and were generally mild to moderate. Part 1 + 2 Week 8 CNS Event Analysis: One hundred thirty-two patients were randomized in Part 2, 66 to DOR 100 mg and 66 to EFV. Combining Part 1 and 2, a total of 108 patients received DOR 100 mg and 108 received EFV. By week 8, at least one CNS AE was reported in 22.2% of the DOR group and 43.5% of the EFV group (p<0.001. The most common CNS AEs were dizziness (DOR 9.3%; EFV 27.8%, insomnia (6.5%; 2.8%, abnormal dreams (5.6%; 16.7% and nightmares (5.6%; 8.3%. Conclusions: In ART-naïve, HIV-1-positive

    The Δ32-CCR5 deletion of the CCR5 receptor is protective toward coronary artery pathology and myocardial infarction. Maraviroc (MVC), a CCR5 antagonist, was recently introduced in the therapy of HIV infection; we evaluated whether this drug could modulate the atherosclerotic burden in aviremic PI-treated HIV-positive individuals who underwent MVC intensification. Thus, the effect of MVC on intima media thickness, arterial stiffness, metabolic parameters, pro-inflammatory cytokines, endothelial dysfunction, and microbial traslocation markers was analyzed in 6 aviremic PI-treated HIV-positive individuals and were compared to those obtained in 9 additional aviremic PI-treated subjects that were enrolled retrospectively from our outpatients cohort. MVC intensification resulted in a significant reduction in intima media thickness, pulse wave velocity and triglycerides compared to baseline. Notably, MVC was also associated with a significant reduction of IL-6, microbial translocation indexes, sICAM and sVCAM; these changes were maintained throughout the 6 months of MVC intensification. No significant modifications were observed in CD4 counts, HIV viral load, and cholesterolemia. Results herein support a role of CCR5 antagonists in reducing the cardiovascular risk in HIV-infection. The hampering of inflammation, microbial translocation and the improvement of endothelial function could justify the protective role of CCR5 antagonists on atherosclerotic burden. PMID:27352838

    Full Text Available The objective of present research is to evaluate the lipid lowering efficacy and safety of switching within non-nucleoside reverse transcriptase inhibitors (NNRTI in HIV-infected patients. This is a multicenter, retrospective study utilizing a comprehensive electronic patient registry to identify all adult HIV-infected patients seen from October 1, 1998 through October 1, 2006, who substituted efavirenz for nevirapine (EFV→NVP or vice-versa (NVP→EFV, without change in other antiretrovirals. Lipid profiles before and after the switch were analyzed. A total of 124 patients were identified with 14 male (EFV→NVP, n = 9; NVP→EFV, n = 5 patients meeting the strict criteria for inclusion. An EFV→NVP switch resulted in significant reductions in TC -16% and non-HDL -25% (p≤0.02 and a trend towards a reduction in LDL-C -12%, TG -27%, TC/HDL -23%, TG/HDL -48% and an increase in HDL-C +15% without any changes to BMI, viral or immunological control. However, a NVP→EFV switch appeared to result in a non-significant worsening of LDL-C +29%, HDL-C -8%, TG +36%, non-HDL +28%, TC/HDL +57% and TG/HDL +46%. Lastly, more patients achieved their lipid goals when switched from EFV to NVP. These data suggest that switching from EFV to NVP-based HAART is associated with lipid improvement, however, switching from NVP to EFV-based HAART is associated with worsening of serum lipids.

    This study examined the HIV patients' attitudes towards the practice of organ transplant between HIV patients using a cross-sectional survey design. In total, 206 patients participated with a mean age of 42 (±8.8) years. The majority (70%) were black African and women (54%), and 83% described themselves as heterosexual. Most participants (n = 171, 83%) were on treatment, and 159 (93%) had viral load less than 40 copies/ml. Mean duration of illness and mean duration of treatment were 77 (±42.7) and 68 (±41) months, respectively. Of all participants, 128 (62%) reported that they would consider donating either any organ or a specific organ/s to an HIV patient, 33 (16%) would not consider it and 45 (22%) were unsure about donating their organs. Furthermore, 113 (55%) participants would consider receiving an organ from an HIV patient, 37 (18%) would not consider it, and 56 (27%) were unsure. Ninety-eight participants (42%) reported that they would consider both donating and receiving an organ. Multinomial logistic regression analysis found that significantly more Black African than Caucasian participants were unsure about organ donation (p = 0.011, OR = 3.887). Participants with longer duration of infection were significantly less likely to consider receiving an organ from an HIV patient (p = 0.036, OR = 1.297). Overall, the study findings indicated that the majority of participants were in favour of organ transplant between HIV patients. Use of HIV-infected donors could potentially reduce current organ waiting list among HIV patients. PMID:25614524

    Abacavir/lamivudine (ABC/3TC) is a nucleoside reverse transcriptase inhibitor used for treating human immunodeficiency viral (HIV) infections. Hypersensitivity reactions such as skin eruptions caused by ABC are well-known, but rarely occur in Asians. Raltegravir (RAL) is an integrase strand transfer inhibitor, that is now increasingly, used for treating HIV infections because it has few adverse effects. This retrospective analysis assessed the efficacy and safety of combined ABC/3TC and RAL in both treatment-naïve and -experienced Japanese patients with HIV infections. In all 11 treatment-naïve patients (100%), virological suppression to undetectable level was achieved. Liver transaminases, renal function, and serum lipid profiles showed no exacerbations up to 48 weeks of treatment. In 12 patients who were switched from previous regimens to ABC/3TC and RAL, HIV viral load was undetectable in 11 patients (91.6%), but remained detectable in 1 patient with poor adherence. Major reasons for switching regimens to ABC/3TC and RAL were hyperlipidemia and nausea. After switching, these adverse effects improved, and no new adverse effects were observed. Despite the small number of participants in this study, the results support the combination of ABC/3TC and RAL as a possible treatment choice in Japanese individuals with HIV-infection.

    2008-01-01

    The use of antiretroviral therapy (ART) to treat HIV infection, by restoring CD4+ cell count and immune function, is associated with significant reductions in morbidity and mortality. Soon after ART initiation, there is a rapid phase of restoration of pathogen-specific immunity. In certain patients......, this results in inflammatory responses that may result in clinical deterioration known as 'the immune reconstitution inflammatory syndrome' (IRIS). IRIS may be targeted at viable infective antigens, dead or dying infective antigens, host antigens, tumour antigens and other antigens, giving rise to a...... heterogeneous range of clinical manifestations. The commonest forms of IRIS are associated with mycobacterial infections, fungi and herpes viruses. In most patients, ART should be continued and treatment for the associated condition optimized, and there is anecdotal evidence for the use of corticosteroids in...

    Background Over the last years, the mean age of subjects with HIV infection and AIDS is increasing. Moreover, some epidemiological and clinical differences between younger and older HIV-infected individuals have been observed. However, since introduction of HAART therapy, there are controversial results regarding their response to HAART. The aim of the present study is to evaluate epidemiological and clinical features, response to HAART, and survival in elderly HIV-infected patients with regard to younger HIV-infected patients. Methods A prospective cohort study (1998–2003) was performed on patients from Sabadell Hospital, in Northeast of Spain. The cohort includes newly attended HIV-infected patients since January 1, 1998. For the purpose of this analysis, data was censured at December 31, 2003. Taking into account age at time of diagnosis, it was considered 36 HIV-positive people aged 50 years or more (Group 1, G1) and 419 HIV-positive people aged 13–40 years (Group 2, G2). Epidemiological, clinical, biological and therapy data are recorded. Statistical analysis was performed using Chi-squared test and Fisher exact test, Mann-Whitney U test, Kaplan-Meier, Log Rank test, and Two-Way ANOVA from random factors. Results G1 showed higher proportion of men than G2. The most common risk factors in G1 were heterosexual transmission (P = 0.01) and having sex with men or women (P < 0.001). G1 and G2 show parallel profiles through the time regarding immunological response (P = 0.989) and virological response (P = 0.074). However, older people showed lower CD4 cell counts at first clinic visit (P < 0.001) and, eventually, they did not achieve the same counts as G2. G1 presented faster progression to AIDS (P < 0.001) and shorter survival (P < 0.001). Conclusion Older patients have different epidemiological features. Their immunological and virological responses are good. However, older patients do not achieve the same CD4 cell counts likely due to they have lower counts

    We aimed to determine the prevalence of MRSA colonization and examine the molecular characteristics of colonizing isolates in patients receiving hemodialysis and HIV-infected in a Colombian hospital. Patients on hemodialysis and HIV-infected were prospectively followed between July 2011 and June 2012 in Bogota, Colombia. Nasal and axillary swabs were obtained and cultured. Colonizing S. aureus isolates were identified by standard and molecular techniques. Molecular typing was performed by using pulse-field gel electrophoresis and evaluating the presence of lukF-PV/lukS-PV by PCR. A total of 29% (n = 82) of HIV-infected and 45.5% (n = 15) of patients on hemodialysis exhibited S. aureus colonization. MSSA/MRSA colonization was observed in 28% and 3.6% of the HIV patients, respectively and in 42.4% and 13.3% of the hemodialysis patients, respectively. Staphylococcal cassette chromosome mec typing showed that four MRSA isolates harbored the type IV cassette, and one type I. In the hemodialysis group, two MRSA isolates were classified as belonging to the USA300-LV genetic lineage. Conversely, in the HIV infected group, no colonizing isolates belonging to the USA300-Latin American Variant (UDA300-LV) lineage were identified. Colonizing isolates recovered from the HIV-infected group belonged to the prevalent hospital-associated clones circulating in Latin America (Chilean [n = 1] and Pediatric [n = 2]). The prevalence of MRSA colonization in the study groups was 3.6% (HIV) and 13.3% (hemodialysis). Surveillance programs should be implemented in this group of patients in order to understand the dynamics of colonization and infection in high-risk patients. PMID:26474075

    Full Text Available Abstract The HIV/AIDS pandemic is primarily caused by HIV-1. Another virus type, HIV-2, is found mainly in West African countries. We hypothesized that population migration and mobility in Africa may have facilitated the introduction and spreading of HIV-2 in Mozambique. The presence of HIV-2 has important implications for diagnosis and choice of treatment of HIV infection. Hence, the aim of this study was to estimate the prevalence of HIV-2 infection and its genotype in Maputo, Mozambique. HIV-infected individuals (N = 1,200 were consecutively enrolled and screened for IgG antibodies against HIV-1 gp41 and HIV-2 gp36 using peptide-based enzyme immunoassays (pepEIA. Specimens showing reactivity on the HIV-2 pepEIA were further tested using the INNO-LIA immunoblot assay and HIV-2 PCR targeting RT and PR genes. Subtype analysis of HIV-2 was based on the protease gene. After screening with HIV-2 pepEIA 1,168 were non-reactive and 32 were reactive to HIV-2 gp36 peptide. Of this total, 30 specimens were simultaneously reactive to gp41 and gp36 pepEIA while two samples reacted solely to gp36 peptide. Only three specimens containing antibodies against gp36 and gp105 on the INNO-LIA immunoblot assay were found to be positive by PCR to HIV-2 subtype A. The proportion of HIV-2 in Maputo City was 0.25% (90%CI 0.01-0.49. The HIV epidemic in Southern Mozambique is driven by HIV-1, with HIV-2 also circulating at a marginal rate. Surveillance program need to improve HIV-2 diagnosis and consider periodical survey aiming to monitor HIV-2 prevalence in the country.

    The present report documents a 49-year-old HIV-infected man receiving antiretroviral therapy with a suboptimal immune response and a CD4 count of 95 cells/mm(3), despite virological suppression. Investigation of bone marrow was conducted and yielded a diagnosis of visceral leishmaniasis. The clinical course was complicated by gastrointestinal involvment and relapse occurred after amphotericin B therapy. With the addition of miltefosine, the patient no longer presented with bone marrow amastigotes, and displayed an increased CD4 count and negative Leishmania polymerase chain reaction results. The present case highlights atypical presentation of visceral leishmaniasis, including poor immune reconstitution and gastrointestinal involvement. The high likelihood of relapse and response to combination therapy are illustrated. PMID:26744591

    This is the first Romanian investigation of oral candidosis in patients suffering of HIV-infection or type 1 diabetes mellitus (T1DM). Candida albicans was the dominant species in both types of isolates: n = 14 (46.7%) in T1DM, n = 60 (69.8%) in HIV. The most frequent non-albicans Candida spp. were Candida kefyr (n = 6; 20%) in T1DM and Candida dubliniensis (n = 8; 9.3%) in HIV. Resistance to fluconazole was detected only in the HIV non-albicans Candida group (n = 8; 9.3%). All isolates were susceptible to VOR. The experimental drug MXP had MIC values equal or close to the ones of VOR. Echinocandin resistance was more frequent than azole resistance. PMID:27282005

    Full Text Available BACKGROUND: Interferon-gamma release assays (IGRAs have provided a new method for the diagnosis of Mycobacterium tuberculosis infection. However, the role of IGRAs for the diagnosis of active tuberculosis (TB, especially in HIV-infected patients remains unclear. METHODS: We searched PubMed, EMBASE and Cochrane databases to identify studies published in January 2001-July 2011 that evaluated the evidence of using QuantiFERON-TB Gold in-tube (QFT-GIT and T-SPOT.TB (T-SPOT on blood for the diagnosis of active TB in HIV-infected patients. RESULTS: The search identified 16 eligible studies that included 2801 HIV-infected individuals (637 culture confirmed TB cases. The pooled sensitivity for the diagnosis of active TB was 76.7% (95%CI, 71.6-80.5% and 77.4% (95%CI, 71.4-82.6% for QFT-GIT and T-SPOT, respectively, while the specificity was 76.1% (95%CI, 74.0-78.0% and 63.1% (95%CI, 57.6-68.3% after excluding the indeterminate results. Studies conducted in low/middle income countries showed slightly lower sensitivity and specificity when compared to that in high-income countries. The proportion of indeterminate results was as high as 10% (95%CI, 8.8-11.3% and 13.2% (95%CI, 10.6-16.0% for QFT-GIT and T-SPOT, respectively. CONCLUSION: IGRAs in their current formulations have limited accuracy in diagnosing active TB in HIV-infected patients, and should not be used alone to rule out or rule in active TB cases in HIV-infected patients. Further modification is needed to improve their accuracy.

    Full Text Available Peripheral blood interferon-gamma release assays (IGRAs have sub-optimal sensitivity and specificity for diagnosis of active pulmonary tuberculosis (TB. However, assessment of local immune responses has been reported to improve the accuracy of TB diagnosis.We enrolled HIV-infected adults with cough ≥2 weeks' duration admitted to Mulago Hospital in Kampala, Uganda and referred for bronchoscopy following two negative sputum acid-fast bacillus smears. We performed an ELISPOT-based IGRA (T-SPOT.TB®, Oxford Immunotec, Oxford, UK using peripheral blood and bronchoalveolar lavage (BAL fluid mononuclear cells, and determined the accuracy of IGRAs using mycobacterial culture results as a reference standard.94 HIV-infected patients with paired peripheral blood and BAL IGRA results were included. The study population was young (median age 34 years [IQR 28-40 years] and had advanced HIV/AIDS (median CD4+ T-lymphocyte count 60 cells/µl [IQR 22-200 cells/µl]. The proportion of indeterminate IGRA results was higher in BAL fluid than in peripheral blood specimens (34% vs. 14%, difference 20%, 95% CI 7-33%, p = 0.002. BAL IGRA had moderate sensitivity (73%, 95% CI 50-89% but poor specificity (48%, 95% CI 32-64% for TB diagnosis. Sensitivity was similar (75%, 95% CI 57-89% and specificity was higher (78%, 95% CI 63-88% when IGRA was performed on peripheral blood.BAL IGRA performed poorly for the diagnosis of smear-negative TB in a high HIV/TB burden setting. Further studies are needed to examine reasons for the large proportion of indeterminate results and low specificity of BAL IGRA for active TB in high HIV/TB burden settings.

    The diagnostic value of the CD4 cell counts and the HIV p24 antigen were evaluated in a consecutive series of 105 HIV-infected patients experiencing 128 episodes of pulmonary symptoms which required bronchoscopy. One-third of patients with opportunistic infection (OI) had CD4 counts greater than 0.......200 x 10(9)/l, and 60% of patients without OI had CD4 counts less than 0.200 x 10(9)/l; 47 and 42% of patients with and without OI, respectively, had detectable p24 antigen in serum. Only 36% of the patients with OI presented the combination of CD4 cells less than 0.200 x 10(9)/l and p24 in serum. In...... conclusion, the CD4 cell counts and the presence of p24 antigen in serum had a very limited predictive value for the presence of OI in HIV-infected patients with pulmonary symptoms....

    Full Text Available BACKGROUND: Predictors of death in hospitalized HIV-infected patients have not been previously reported in Bangladesh. OBJECTIVE: The primary aim of this study was to determine predictors of death among hospitalized HIV-infected patients at a large urban hospital in Bangladesh. METHODS: A study was conducted in the HIV in-patient unit (Jagori Ward of icddr,b's Dhaka Hospital. Characteristics of patients who died during hospitalization were compared to those of patients discharged from the ward. Bivariate analysis was performed to determine associations between potential risk factors and death. Multivariable logistic regression was used to identify factors independently associated with death. RESULTS: Of 293 patients admitted to the Jagori Ward, 57 died during hospitalization. Most hospitalized patients (67% were male and the median age was 35 (interquartile range: 2-65 years. Overall, 153 (52% patients were diagnosed with HIV within 6 months of hospitalization. The most common presumptive opportunistic infections (OIs identified were tuberculosis (32%, oesophageal candidiasis (9%, Pneumocystis jirovecii pneumonia (PJP (8%, and histoplasmosis (7%. On multivariable analysis, independent predictors of mortality were CD4 count ≤200 cells/mm3 (adjusted odds ratio [aOR]: 16.6, 95% confidence interval [CI]: 3.7-74.4, PJP (aOR: 18.5, 95% CI: 4.68-73.3, oesophageal candidiasis (aOR: 27.5, 95% CI: 5.5-136.9, malignancy (aOR:15.2, 95% CI: 2.3-99.4, and bacteriuria (aOR:7.9, 95% CI: 1.2-50.5. Being on antiretroviral therapy prior to hospitalization (aOR: 0.2, 95% CI: 0.06-0.5 was associated with decreased mortality. CONCLUSION: This study showed that most patients who died during hospitalization on the Jagori Ward had HIV-related illnesses which could have been averted with earlier diagnosis of HIV and proper management of OIs. It is prudent to develop a national HIV screening programme to facilitate early identification of HIV.

  5. Efficacy of Pravastatin in Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI and Protease Inhibitor (PI-based HAART in HIV-Infected Patients

    Full Text Available Pravastatin has generally been considered a safe and effective option for HIV-infected patients on highly active antiretroviral therapy (HAART. However, pravastatin concentrations are known to significantly decrease with concomitant efavirenz (EFV use. Currently there are no studies determining if these reductions in pravastatin possibly translate into an attenuation of its lipid lowering efficacy when used in HIV-infected patients on non-nucleoside reverse transcriptase inhibitor (NNRTI-based HAART. To evaluate the differences in the lipid lowering efficacy of pravastatin for the treatment of dyslipidemia in HIV-infected patients on NNRTI-based HAART compared to protease inhibitor (PI-based regimens. A single center, retrospective evaluation of a comprehensive electronic HIV registry that identified HIV-infected, Veterans Affairs (VA patients who received pravastatin 20 mg plus NNRTI or PI-based HAART from January 1997 to November 2006 who met the strict criteria for inclusion. A total of 18 patients [NNRTI (n = 7 and PI (n = 11] met the strict criteria for inclusion. In HIV-infected patients taking NNRTI-based HAART there was a reduction in TC by -10.1%, LDL by -12% and non-HDL by -12.2% within 6 months after starting pravastatin 20 mg. In HIV-infected patients taking PI-based HAART, there was a reduction in TC by -10.1%, in LDL by -21.1% and in non-HDL by -13.8% within 6 months after starting pravastatin 20 mg. In both groups, only one additional patient achieved their patient specific lipid goals. In either group these reductions were seen without any apparent adverse drug events or compromise to virologic or immunologic control. This initial evaluation suggests that pravastatin’s efficacy may be attenuated with NNRTIs versus PI-based HAART, possibly due to known reductions in pravastatin concentrations when administered with NNRTI-based regimens. These effects were seen without any apparent compromises to safety and should be validated in

    Full Text Available Jose G Castro1, Maya Morrison-Bryant21Division of Infectious Diseases, University of Miami Miller School of Medicine, Miami, Florida, USA; 2Jackson Memorial Hospital/University of Miami Infectious Diseases Fellowship Program, Miami, Florida, USAAbstract: The discovery of the Human Immunodeficiency Virus (HIV was led by the merge of clustered cases of Pneumocystis jirovecii Pneumonia (PCP in otherwise healthy people in the early 80’s.1,2 In the face of sophisticated treatment now available for HIV infection, life expectancy approaches normal limits. It has dramatically changed the natural course of HIV from a nearly fatal infection to a chronic disease.3–5 However, PCP still remains a relatively common presentation of uncontrolled HIV. Despite the knowledge and advances gained in the prevention and management of PCP infection, it continues to have high morbidity and mortality rates. Trimethoprim-sulfamethoxazole (TMP-SMZ remains as the recommended first-line treatment. Alternatives include pentamidine, dapsone plus trimethoprim, clindamycin administered with primaquine, and atovaquone. For optimal management, clinicians need to be familiar with the advantages and disadvantages of the available drugs. The parameters used to classify severity of infection are also important, as it is well known that the adjunctive use of steroids in moderate to severe cases have been shown to significantly improve outcome. Evolving management practices, such as the successful institution of early antiretroviral therapy, may further enhance overall survival rates.Keywords: HIV, Pneumocystis Jirovecii, PCP, TMP-SMZ

  7. 9G4 autoreactivity is increased in HIV-infected patients and correlates with HIV broadly neutralizing serum activity.

    Directory of Open Access Journals (Sweden)

    James J Kobie

    Full Text Available The induction of a broadly neutralizing antibody (BNAb response against HIV-1 would be a desirable feature of a protective vaccine. Vaccine strategies thus far have failed to elicit broadly neutralizing antibody responses; however a minority of HIV-infected patients do develop circulating BNAbs, from which several potent broadly neutralizing monoclonal antibodies (mAbs have been isolated. The findings that several BNmAbs exhibit autoreactivity and that autoreactive serum antibodies are observed in some HIV patients have advanced the possibility that enforcement of self-tolerance may contribute to the rarity of BNAbs. To examine the possible breakdown of tolerance in HIV patients, we utilized the 9G4 anti-idiotype antibody system, enabling resolution of both autoreactive VH4-34 gene-expressing B cells and serum antibodies. Compared with healthy controls, HIV patients had significantly elevated 9G4+ serum IgG antibody concentrations and frequencies of 9G4+ B cells, a finding characteristic of systemic lupus erythematosus (SLE patients, both of which positively correlated with HIV viral load. Compared to the global 9G4-IgD--memory B cell population, the 9G4+IgD--memory fraction in HIV patients was dominated by isotype switched IgG+ B cells, but had a more prominent bias toward "IgM only" memory. HIV envelope reactivity was observed both in the 9G4+ serum antibody and 9G4+ B cell population. 9G4+ IgG serum antibody levels positively correlated (r = 0.403, p = 0.0019 with the serum HIV BNAbs. Interestingly, other serum autoantibodies commonly found in SLE (anti-dsDNA, ANA, anti-CL did not correlate with serum HIV BNAbs. 9G4-associated autoreactivity is preferentially expanded in chronic HIV infection as compared to other SLE autoreactivities. Therefore, the 9G4 system provides an effective tool to examine autoreactivity in HIV patients. Our results suggest that the development of HIV BNAbs is not merely a consequence of a general breakdown in

  8. Ritonavir-boosted darunavir is rarely associated with nephrolithiasis compared with ritonavir-boosted atazanavir in HIV-infected patients.

    Full Text Available BACKGROUND: Although ritonavir-boosted atazanavir (ATV/r is known to be associated with nephrolithiasis, little is known about the incidence of nephrolithiasis in patients treated with ritonavir-boosted Darunavir (DRV/r, the other preferred protease inhibitor. METHODS: In a single-center cohort, the incidence of nephrolithiasis was compared between HIV-infected patients who commenced DRV/r-containing antiretroviral therapy and those on ATV/r. The effects of ATV/r use over DRV/r were estimated by univariate and multivariate Cox hazards models. RESULTS: Renal stones were diagnosed in only one patient (0.86 per 1000 person-years of the DRV/r group (n=540 and 37 (20.2 per 1000 person-years of the ATV/r group (n=517. The median [interquartile (IQR] observation period in the DRV/r group was 27.1 months (IQR 18.1-38.4 months, and 40.6 months (IQR 17.5-42.7 for the ATV/r group. The total observation period was 1,163.6 person-years and 1,829.6 person-years for the DRV/r group and for the ATV/r group, respectively. In the 37 patients on ATV/r who developed nephrolithiasis, the median time from commencement of ATV/r to diagnosis was 28.1 months (IQR 18.4-42.7, whereas nephrolithiasis in the single patient of the DRV/r group occurred 11.2 month after the introduction of DRV/r. ATV/r use over DRV/r was significantly associated with nephrolithiasis by uni- and multivariate analyses (HR=26.01; 95% CI, 3.541-191.0; p=0.001 (adjusted HR=21.47; 95% CI, 2.879-160.2; p=0.003. CONCLUSION: The incidence of nephrolithiasis was substantially lower in patients on DRV/r than those on ATV/r. The results suggest that DRV/r should be selected for treatment of HIV-infected patients at risk of chronic kidney disease.

    Full Text Available Abstract Context The natural course of HIV disease progression among resource-poor patient populations has not been clearly defined. Objective To describe predictors of HIV disease progression as seen at an outpatient clinic in a resource-limited setting in rural Ethiopia. Design This prospective cohort study included all adult HIV patients who visited an outpatient clinic at Arba Minch hospital in South Ethiopia between January 30, 2003 and April 1, 2004. Clinical and hematologic measurements were done at baseline and every 12 weeks thereafter until the patient was transferred, put on antiretroviral therapy, was lost to follow-up, or died. Community agents reported patient status every month. Setting A district hospital with basic facilities for HIV testing and patient monitoring. Main Outcome Measures Death, diagnosis of tuberculosis, and change in disease stage. Results We followed 207 patients for a median duration of 19 weeks (range, 0–60 weeks. A total of 132 (64% of them were in WHO stage III. The overall mortality rate was 46 per 100 person-years of observation (PYO. Mortality increased with advancing disease stage. Diarrhea, oral thrush, and low total lymphocyte count were significant markers of mortality. The incidence of tuberculosis was 9.9 per 100 PYO. Baseline history of easy fatigability and fever were strongly associated with subsequent development of tuberculosis. Conclusion The mortality rate and the incidence of tuberculosis in our cohort are among the highest ever reported in sub-Saharan Africa. We identified oral thrush, diarrhea, and total lymphocyte count as predictors of mortality, and easy fatigability and fever as predictors of tuberculosis. The findings have practical implications for patient care in resource-limited settings.

    Objective was to assess dietary intake and physical activity in a Canadian population sample of male patients with HIV and metabolic abnormalities and to compare the data to Canadian recommendations. Sixty-five HIV-infected men with at least one feature associated with the metabolic syndrome (insulin resistance, dyslipidemia, central obesity, or lipodystrophy) were enrolled. Results from 7-day food records and activity logs were compared to the Dietary Reference Intakes and recommendations of Canada's Physical Activity Guide, respectively. Anthropometric data were also measured. Fifty-two percent of the subjects were overweight, another 15% were obese. However, energy intake (mean+/-SEM) (2153+/-99 kcal/d) was lower than the estimated requirement (2854+/-62 kcal/d; p<0.0001), and 84.5% of the patients reached the recommended minimum of 60 min of mild or 30 min of moderate daily exercise. Intake was adequate for protein, but high for fat and cholesterol in 40% of patients. No patient reached the recommendation for fiber. Intake from diet alone was suboptimal for most micronutrients. Prevalence was highest for low vitamin E (91% of patients) and magnesium (68%) intake, and high sodium intake (72%). In summary, a large proportion of HIV patients with metabolic abnormalities were overweight or obese. However, this was not associated with high energy intake, or reduced physical activity. High fat, low fiber and inadequate micronutrient intakes were prevalent. PMID:18288980

METHOD: A cross-sectional study with a face-to-face questionnaire interview was conducted among eligible participants. RESULTS: In total, 455 (94.4% out of 482 eligible HIV patients participated in the study. Of them, 82.6% were ethnic minorities; 15.4% were never married; 96.5% were sexually experienced; 55.4% had used drugs, 67% were receiving antiretroviral therapy (ART. Over 65% were ever drinkers; of whom 61.5% were current drinkers. Among current drinkers, 32.4% drank daily and 41.2% were hazardous drinkers. Chinese white wine was the preferred choice. Higher level of alcohol use among drinkers in the preceding month was positively associated with being males (OR = 2.76, 95%CI: 1.03-7.43, ethnic minorities (OR Jingpo = 2.21, 95%CI: 1.06-4.59; OR other minorities = 3.20, 95%CI: 1.34-7.62, higher education (OR1-6 = 1.98, 95%CI: 0.99-3.96; OR≥7 = 2.35, 95%CI: 1.09-5.06 and being ART-naive (OR = 2.69, 95%CI: 1.67-4.32. About 39% of ever drinkers reported having engaged in sex after drinking since HIV diagnosis. Those who were younger than 46 years (OR16-25 = 7.77, 95%CI: 1.22-49.60, OR26-35 = 2.79, 95%CI: 1.06-7.35, OR36-45 = 2.96, 95%CI: 1.57-7.58, hazardous drinkers (OR = 1.99, 95%CI: 1.00-3.97 and drug users (OR = 3.01, 95%CI: 1.19-7.58 were more likely to have had sex after drinking. Approximately 56% of drug users had used drugs after drinking. CONCLUSIONS: High prevalence of alcohol use and subsequent risky behaviors including sexual engagement and drug use among HIV patients in rural Yunnan require tremendous and integrated efforts for prevention and control of alcohol and drug abuse and HIV spreading.

The comparisons were performed with the help of a Markov decision model over a 10-year time horizon. Based on the ADONE (ADherence to ONE pill study, it was then possible to identify the utility score increment in patients switching from a multipill regimen of TDF-FTC + EFV therapy to a single-tablet regimen.Results: The single-tablet regimen (0.755 quality-adjusted life-years [QALYs]/year resulted in better patient quality of life, with a higher number of QALYs than for the TDF-FTC + EFV multipill regimen (0.716 QALYs/year. The single-tablet regimen was the most cost-effective treatment strategy, with an incremental cost-effectiveness ratio of €22,017.00 versus €26,558.00 for the multipill regimen. A 24% decrease in cost of the multipill regimen determined equivalence with the single-tablet regimen in terms of the incremental cost-effectiveness ratio. Univariate sensitivity and probabilistic analysis carried out on the main variables did not highlight significant variations with respect to the base case scenario.Conclusion: The single-tablet regimen resulted in better adherence, and therefore better quality of life as perceived by patients, corresponding to a €4541.00 lower

    Full Text Available Introduction: HIV-infected patients treated with Highly Active Antiretroviral Therapy (HAART may be predisposed to hypertriglyceridemia, which gives rise to a highly atherogenic lipid profile known as atherogenic dyslipidemia (AD. We propose that genetic variability leaves some HIV-infected patients more predisposed to AD than others (1, 2. Methods: This was a cross-sectional, observational study conducted in 468 antiretroviral-treated HIV-infected patients attending at the outpatient clinic of a tertiary hospital over a 6-month period, who were classified as normolipidemic (n=173 or presenting with AD (triglycerides: 1.7 mmol/L and HDLc < 1.02 [men] or 1.28 mmol/L [women] (n=148. Polymorphisms were identified in the APOA5, APOC3, LPL, CETP, HL, MTP, APOE, LRP5 and VLDLR genes. Results: Atherogenic dyslipidemia was detected in 31% of patients, most of whom were men (77%. This group was also older and had higher levels of remnant lipoprotein cholesterol (RLPc than normolipidemic patients. The polymorphisms rs328 in LPL, rs708272 in CETP and rs1800588 in HL were 10–40% significantly more frequent in normolipidemic patients. At least 1 of these polymorphisms was detected in 90% of normolipidemic patients; in AD patients, the percentage decreased to 75% (p=0.003. This effect was dependent on both the allele and the dose of HAART and independent of the regimen administered. The protective combination showed a trend towards higher HDLc (1.13 [0.40] vs 1.24 [0.23] mmol/L, lower triglycerides (2.23 [2.34] vs 1.89 [1.24] mmol/L and lower RLPc (16.41 [11.42] vs 12.99 [11.69] mmol/L. Conclusions: Polymorphisms in LPL, CETP and HL protect HIV-infected patients from developing AD in a dose-dependent manner (3.

    Purpose The impact of pharmacist-assisted management (PAM) of pharmacotherapy for patients with human immunodeficiency virus (HIV) infection was investigated. Methods A retrospective cohort analysis was conducted to evaluate antiretroviral therapy (ART) outcomes in treatment-naive patients initiated on ART at an HIV clinic. Eligible patients enrolled in the clinic during the period 1999–2013 were classified into two groups: those referred to a clinic-based HIV pharmacist for initiation of ART (the PAM group) and those managed by a primary care provider (the control group). The primary study objective was the median time to viral suppression; secondary objectives included the durability of response to the first ART regimen. Relative hazards for the events of interest were estimated using a marginal structural Cox proportional hazards model and Kaplan–Meier curves, with inverse probability weights used to control for selection and confounding bias. Results Patients referred for PAM services (n = 819) typically had higher baseline viral loads and lower CD4+ cell counts than those in the control group (n = 436). The likelihood of viral suppression during the first two years after ART initiation was significantly higher in the PAM group versus the control group (hazard ratio, 1.37; 95% confidence interval, 1.18–1.59; p 0.05). Conclusion In treatment-naive patients, suppression of HIV viral load occurred earlier when pharmacists assisted with initiating ART than when ART was initiated without that assistance.

    Full Text Available BACKGROUND: Psychological factors are known predictors of cardiovascular disease in many clinical settings, but data are lacking for HIV infection. We carried out a prospective cohort study to evaluate potential psychological predictors of preclinical and clinical vascular disease in HIV patients. METHODOLOGY/PRINCIPAL FINDINGS: HIV patients were consecutively enrolled. Demographics, viral and immune parameters and traditional cardiovascular predictors were considered; Intima-Media Thickness (c-IMT, continuous measure and Carotid Plaques (CPs, focal thickening ≥1.5 mm were investigated by B-mode ultrasonography; depressive symptoms by the Beck Depression Inventory (BDI-II, Type D personality (Distressed Personality or Type D by the DS14, alexithymia by the Toronto Alexithymia Scale (TAS-20. Vascular outcomes included transient ischemic attacks or stroke, acute coronary syndrome, myocardial or other organ infarction. We enrolled 232 HIV subjects, 73.9% males, aged 44.5±9.9 y, 38.2% with AIDS diagnosis, 18.3% untreated. Mean Nadir CD4 T-cell counts were 237.5±186.2/mmc. Of them, 224 (96.5% attended IMT measurements; 201 (86.6% attended both IMT assessment and psychological profiling. Mean follow-up was 782±308 days. Fifty-nine patients (29.4% had CPs at baseline. Nineteen patients (9.5% had ≥1 vascular event; 12 (6.0% died due to such events (n = 4 or any cause. At baseline cross-sectional multivariate analysis, increasing age, total cholesterol, current smoking and Alexithymia score≥50 were significantly associated with both increased cIMT (linear regression and CPs (logistic regression. At follow-up analysis, log-rank tests and Cox's regression revealed that only older age (p = 0.001, current smoking (p = 0.019 and alexithymia score≥50 (p = 0.013 were independently associated with vascular events. CONCLUSIONS/SIGNIFICANCE: In HIV-infected subjects, the Alexithymic trait emerges as a strong predictor of increased IMT, presence of CPs

    Long-term results (>5 years) for synthetic substances used to repair facial lipoatrophy have not been published. We performed a cross-sectional study to evaluate the 10-year safety of polyacrylamide hydrogel (Aquamid) among the 751 patients from our unit who received facial infiltrations at least 10 years ago. Epidemiological and clinical data such as complications and patient satisfaction were collected. We also identified those patients who presented a facial infection at any time after infiltration. A total of 104 patients had received Aquamid at least 10 years ago. Before infiltrations, 24.0%, 41.3%, and 34.7% presented very severe, severe, and moderate facial lipoatrophy, respectively. After a mean (SD) of 10.3 (0.5) years since the infiltrations, 19.2%, 47.7%, and 31.7% of patients reported moderate, mild, and no signs of facial lipoatrophy. The values reported by physicians for the same categories were 1.9%, 10.6%, and 87.5%. Indurations were detected in 6.7% of patients and nodules in 3.8%. Five patients (4.8%) had a local infection. A further 15 patients with a shorter follow-up (less than 10 years) presented local infections (overall incidence considering the 751 patients who received infiltrations of Aquamid, 2.7%); the product had to be withdrawn in three cases. The majority of patients were highly satisfied (74.8%) or satisfied (23.4%) with the cosmetic results; among patients with severe or very severe lipoatrophy at baseline, 31.4% were satisfied and 65.7% were highly satisfied. Infiltrations with polyacrylamide hydrogel (Aquamid) are a safe strategy for the treatment of facial lipoatrophy in the long term. The rate of severe complications was low, and patient satisfaction with the cosmetic results was high. However, facial infections may appear in the long term. Therefore, HIV-infected patients who received synthetic substances should be carefully monitored over time. PMID:25858612

    Non-small-cell lung cancer (NSCLC) is the most common non-acquired immune deficiency syndrome-related malignancy responsible for death. Mutational status is crucial for choosing treatment of advanced NSCLC, yet no data is available on the frequency of epidermal growth factor receptor (EGFR) and Kirsten ras (KRAS) mutations and their impact on NSCLC in human immunodeficiency virus (HIV)-infected patients (HIV-NSCLC). All consecutive HIV-NSCLC patients diagnosed between June 1996 and August 2013 at two Paris university hospitals were reviewed, with tumor samples analyzed for EGFR and KRAS mutational status. Overall, 63 tumor samples were analyzed out of 73 HIV-NSCLC cases, with 63% of advanced NSCLC. There were 60 non-squamous and nine squamous cell carcinomas, with EGFR and KRAS mutations identified in two (3.3%) and seven (11.5%) tumors, respectively. The proportion of KRAS mutations was 29% if solely the more sensitive molecular techniques were considered. The two patients with advanced adenocarcinoma harboring EGFR mutations exhibited lasting partial response to EGFR-tyrosine kinase inhibitors. Overall survival for patients with advanced NSCLC were >30 months for those with EGFR mutations, impact, whereas KRAS mutation is of poor prognostic value. Clinicians should search for drugs dedicated to this target population. PMID:27133754

    BACKGROUND: HIV-infected patients could exhibit accelerated ageing, since age-associated complications like sarcopenia; increased inflammation; lipodystrophy with loss of subcutaneous adipose tissue and/or gain of visceral adipose tissue (VAT); and cardiovascular disease occur at an earlier age...... receptor (suPAR) were associated distinctively with adiposity, lipodystrophy and sarcopenia, in HIV-infected patients and healthy Controls. RESULTS: Systemic leptin levels were significantly higher in patients with lipodystrophy than without, whereas there was no difference in IL-6 or suPAR levels. Leptin...... adiposity- and lipodystrophy-related inflammation, but not sarcopenia. IL-6 reflected both adiposity-, but also sarcopenia-related inflammation; and suPAR was a marker of sarcopenia-related inflammation.

    Full Text Available Cryptococcal meningitis (CM is a common cause of death among HIV infected patients in developing countries, especially in sub-Saharan Africa. In this observational HIV cohort study in a resource-limited setting in India, we compared the standard two-week intravenous amphotericin B deoxycholate (AmBd (Regimen I with one week of intravenous AmBd along with daily therapeutic lumbar punctures and intrathecal AmB lipid emulsion (Regimen II during the intensive phase of CM treatment. 78 patients received Regimen I and 45 patients received Regimen II. After adjustment for baseline characteristics (gender, age, altered mental status or seizures at presentation, CD4 cell count, white blood cells, cerebrospinal fluid white cells, and haemoglobin, the use of Regimen II was associated with a significant relative risk reduction in mortality (adjusted hazard ratio 0.4, 95% confidence interval, 0.22–0.76 and 26.7% absolute risk reduction (95% confidence interval, 9.9–43.5 at 12 weeks. The use of Regimen II resulted in lower costs of drugs and hospital admission days. Since the study is observational in nature, we should be cautious about our results. However, the good tolerability of intrathecal administration of AmB lipid emulsion and the clinically important mortality reduction observed with the short-course induction treatment warrant further research, ideally through a randomized clinical trial.

    Frederikke Falkencrone Rönsholt

    Full Text Available OBJECTIVES: Immune activation is decreased by combination antiretroviral therapy (cART in patients infected with human immunodeficiency virus (HIV, but residual activation remains and has been proposed as a cause of premature aging and death, but data are lacking. We analyzed the relationship between T-cell subsets after 18 months of cART and overall survival during 12 years of follow up. METHODS: A cohort of 101 HIV infected patients who had undetectable plasma HIV after starting cART was included in 1997-1998. T cell subsets were analyzed by flowcytometry after 18 months of cART. Relation to survival was calculated using Kaplan-Meier curves and multiple Cox regression. RESULTS: Seventeen patients died during the observation period. The leading causes of death were non-AIDS cancer and cardiovascular disease. Higher levels of CD8 memory T cells (CD8+,CD45RO+,CD45RA- showed a significant beneficiary effect on survival, HR of 0.95 (95% confidence interval 0.91-0.99, P = 0.016 when adjusted for age, nadir CD4 count, CD4 count, and AIDS and hepatitis C status. T cell activation was not associated with increased risk of death. CONCLUSIONS: Larger and longitudinal studies are needed to accurately establish prognostic factors, but overall results seem to suggest that prognostic information exists within the CD8 compartment.

    Full Text Available Abstract Background Although severe oral opportunistic infections decreased with the implementation of highly active antiretroviral therapy, periodontitis is still a commonly described problem in patients infected with human immunodeficiency virus (HIV. The objective of the present investigation was to determine possible differences in periodontal parameters between antiretroviral treated and untreated patients. Methods The study population comprised 80 patients infected with HIV divided into two groups. The first group was receiving antiretroviral therapy while the second group was therapy naive. The following parameters were examined: probing pocket depth, gingival recession, clinical attachment level, papilla bleeding score, periodontal screening index and the index for decayed, missed and filled teeth. A questionnaire concerning oral hygiene, dental care and smoking habits was filled out by the patients. Results There were no significant differences regarding the periodontal parameters between the groups except in the clinical marker for inflammation, the papilla bleeding score, which was twice as high (P Conclusion There is no indication for advanced periodontal damage in HIV-infected versus non-infected patients in comparable age groups. Due to their immunodeficiency, HIV-infected patients should be monitored closely to prevent irreversible periodontal damage. Periodontal monitoring and early therapy is recommended independent of an indication for highly active antiretroviral therapy.

    Full Text Available Introduction: The UGT1A1*28 (rs8175347 polymorphism is associated with hyperbilirubinemia. The presence of 6 TA-repeats in the UGT1A1 gene promoter region corresponds to normal UGT1TA1 activity. A detection of 7 TA-repeats in hetero- or homozygous individuals [(TA6/(TA7 and (TA7/(TA7] is associated with lower UGT1TA1 activity, which may eventually result in the development of Gilbert syndrome and/or modified individual response to drugs metabolized by this enzyme. ATV contributes to the decreased levels of UGT1A1, which may lead to elevations of indirect bilirubin, jaundice and even to therapy discontinuation. We evaluated the prevalence of the UGT1A1*28 among HIV-infected patients and the dependence of the frequency and severity of AE during ATV treatment on individual genetic characteristics. Materials and Methods: 47 HIV-infected patients was screen for UGT1A1 genotype and the presence of UGT1A1*28. All patients received ATV in the HAART regimen for 48 weeks. Changes in the total, direct and indirect bilirubin, ALT, AST, GGT and jaundice were evaluated. Statistical analysis was performed using Microsoft Office Excel for Windows XP Professional 2007 and Biostat. Results: All patients were followed up in the AIDS Center (males 72.3%, median age 33 years, median CD4+ count-282 cells/µl (19.5%. HBV/HCV was in 36.2% patients.

    Full Text Available Abstract Background The prevalence of infections with Mycobacterium tuberculosis (MTb and nontuberculous mycobacteria (NTM species in HIV-infected patients in Mexico is unknown. The aims of this study were to determine the frequency of MTb and NTM species in HIV-infected patients from Mexico City, to evaluate the genotypic diversity of the Mycobacterium tuberculosis complex strains, to determine their drug resistance profiles by colorimetric microplate Alamar Blue assay (MABA, and finally, to detect mutations present in katG, rpoB and inhA genes, resulting in isoniazid (INH and rifampin (RIF resistance. Results Of the 67 mycobacterial strains isolated, 48 were identified as MTb, 9 as M. bovis, 9 as M. avium and 1 as M. intracellulare. IS6110-RFLP of 48 MTb strains showed 27 profiles. Spoligotyping of the 48 MTb strains yielded 21 patterns, and 9 M. bovis strains produced 7 patterns. Eleven new spoligotypes patterns were found. A total of 40 patterns were produced from the 48 MTb strains when MIRU-VNTR was performed. Nineteen (39.6% MTb strains were resistant to one or more drugs. One (2.1% multidrug-resistant (MDR strain was identified. A novel mutation was identified in a RIF-resistant strain, GAG → TCG (Glu → Ser at codon 469 of rpoB gene. Conclusions This is the first molecular analysis of mycobacteria isolated from HIV-infected patients in Mexico, which describe the prevalence of different mycobacterial species in this population. A high genetic diversity of MTb strains was identified. New spoligotypes and MIRU-VNTR patterns as well as a novel mutation associated to RIF-resistance were found. This information will facilitate the tracking of different mycobacterial species in HIV-infected individuals, and monitoring the spread of these microorganisms, leading to more appropriate measures for tuberculosis control.

Fasting FFA and LIPOX did not differ between study groups; however, the insulin-mediated suppression of FFA and LIPOX was attenuated in LIPO (P's < .05). Our data indicate...... that higher TNF-alpha, independently of insulin sensitivity, is associated with attenuated insulin-mediated suppression of FFA and LIPOX in HIV-LIPO, suggesting in turn that TNF-alpha stimulates lipolysis in this syndrome. Furthermore, FFA may be a major determinant of LIPOX in HIV-infected patients on...

    The purpose of this study was to characterize changes in the levels of insulin-like growth factor-I (IGF-I) and IGF binding proteins (BP) 1, 2, and 3 in HIV-infected adults throughout the course of their disease, and to assess the responsiveness of the IGF system components to growth hormone (GH) administration (6 mg/day) for 2 weeks. Healthy control study subjects (n = 10) were compared with patients who were either HIV-positive (n = 9), had AIDS without weight loss (n = 13), or had AIDS with >10% weight loss (n = 6), all of whom had been free of acute illness for at least 3 months. Under basal conditions, fasting serum concentrations of epinephrine, norepinephrine, cortisol, glucagon, insulin, IGF-I, and IGFBP-3 were not significantly different among the four groups. The serum concentrations of IGFBP-1 and IGFBP-2 were significantly higher in AIDS patients with wasting than in the other three groups (p < .05). In addition, there was a statistically significant positive correlation between the levels of IGFBP- 1 (p = .004) and IGFBP-2 (p = .03) and the stage of disease. Following GH administration, the serum concentrations of insulin and IGF-I were increased in all groups (p < .05). In addition, the increases in insulin levels correlated with stage of disease (p = .004). The responses of the IGFBPs were more variable. GH administration significantly increased the levels of IGFBP-3 in all groups except the patients with AIDS wasting, whereas the levels of IGFBP-1 were significantly decreased in controls and AIDS patients. These results demonstrate that there is a continuum of both elevations in the IGFBPs and altered metabolic responsiveness in patients infected with HIV that increases with the severity of the disease. These data also demonstrate that AIDS patients, who are free from secondary infection, respond to administration of GH by significantly increasing hepatic IGF-I production. PMID:10534146

    Introduction After the onset of highly active antiretroviral therapy (HAART), some HIV-infected patients present a severe inflammation in response to a latent or a previously treated opportunistic pathogen termed immune reconstitution inflammatory syndrome (IRIS). Few reports of tegumentary and visceral leishmaniasis have been described in association with IRIS. Methods A systematic literature review of IRIS in association with leishmaniasis identified 34 reported cases. Results and Discussion The majority of these occurred in males 4 months following the onset of HAART. The mean CD4 count before HAART was 94 ± 77 cells/mm3, increasing to 5 times the initial value between the onset of HAART and IRIS presentation. Visceral leishmaniasis and post–kala-azar dermal leishmaniasis were the most commonly reported clinical manifestations, followed by tegumentary leishmaniasis and uveitis. Conclusions Commonly found characteristics included cutaneous involvement, regardless of Leishmania species; appearance of lesions unrelated to time of probable Leishmania infection; rapid recovery of CD4 count following HAART; and rapid progression.

    Full Text Available Purpose of the study: Dual therapy with lamivudine plus a PI boosted with ritonavir (PI/r could be an alternative to standard triple therapy or PI/r monotherapy as a simplification strategy in patients with toxicity to nucleoside analogues (NA. Methods: Retrospective cohort study of 44 HIV-infected patients on suppressive HAART, with no chronic HBV, who simplified to this dual therapy since 2008. Virological and immunological outcome, lipids and renal changes were evaluated. Summary of results: Mean age was 50 years (38-70, 66% were male, and the median time of HIV infection was 18.6 years. The median nadir CD4+ count was 150 cells/ml (2–407. At inclusion, patients were receiving therapy with lamivudine plus atazanavir/r in 5 cases, lopinavir/r in 12, and darunavir/r in 27, and they had an HIV RNA level<50 copies/ml for a median time of 794 days (129–2344, 90% >6 months. The NA discontinued was tenofovir (27, didanosine (12, AZT (3, and d4T (2. The reasons for changing were toxicity in 76% of cases, especially renal impairment. They had received a mean of 8 regimens before (2–20, and 55% were in CDC-stage C. In 11 cases, history of resistance was available (to NA in 7 cases, including the 210W mutation in four. The mutations 184V was not observed, but four patients (9% had a previous failure to therapy including 3tC. Mutations in the protease gene were observed in 8 patients (2 to 7 mutations, the most frequent 77I and 93L, without resistance to the current PI/r. During 62.8 patient-years of follow-up (median, 802 days, only 2 patients failed (4.5%, due to incomplete adherence, at 27 and 141 days. Of note, these two patients had no previous failed with 3tC or PI. Overall, CD4+ count increased for 55 cells/ml. No new adverse events were observed, but total cholesterol (from 180 to 246 mg/dl, p=0.007 and triglycerides (from 166 to 195, p=0.01 increased during the first 24 weeks with improvement at 48 weeks.

    Cognitive impairment is common in HIV-infected individuals, as is syphilis. Treponema pallidum, the bacterium that causes syphilis, invades the central nervous system early in disease. We hypothesized that HIV-infected patients with a history of syphilis or neurosyphilis would have more cognitive impairment than HIV-infected individuals without these infections. Eighty-two of 1574 enrollees in CHARTER, a prospective, observational study, had reactive serum rapid plasma reagin (RPR) tests. The...

    Full Text Available Abstract Background Adherence to antiretroviral medication regimens is essential to good clinical outcomes for HIV-infected patients. Little is known about the costs of case management (CM designed to improve adherence for patients identified as being at risk for poor adherence in resource-constrained settings. This study analyzed the costs, outputs, unit costs and correlates of unit cost variation for CM services in 14 ART sites in Ethiopia from October 2008 through September 2009. Methods This study applied standard micro-costing methods to identify the incremental costs of the CM program. We divided total CM-attributable costs by three output measures (patient-quarters of CM services delivered, number of patients served and successful patient exits to derive three separate indices of unit costs. The relationships between unit costs and two operational factors (scale and service-volume to staff ratios were quantified through bivariate analyses. Results The CM program delivered 4,598 patient-quarters of services, serving 5,056 patients and 1,995 successful exits at a cost of $167,457 over 12 months, or $36 per patient-quarter, $33 per patient served and $84 per successful exit from the CM program. Among the 14 sites, mean costs were $11,961 (sd, $3,965 for the 12-month study period, and $51 (sd, $36 per patient-quarter; $48 (sd, $32 per patient served; and $183 (sd, $157 per successful exit. Unit costs varied inversely with scale (r, -0.70 for cost per patient-quarter versus patient-quarters of service and with the service-volume to staff ratio (r, -0.68 for cost per patient-quarter versus staff per patient-quarter. Conclusions For those receiving CM, the program adds 0.52% to the lifetime cost of ART. These data reflect wide variation in unit costs among the study sites and suggest that high patient volume may be a major determinant of CM program efficiency. The observed variations in unit costs also indicate that there may be opportunities to

To date, there is no information about how this trend will behave over the next few years. The aim of the present study is to define a pharmacoeconomic model for the forecast of the costs of a group of chronically treated patients followed over the period 2004–2009.Methods: A pharmacoeconomics model was built to describe the probability of transition among different health states and to modify the therapy over time. A Markov model was applied to evaluate the temporal evolution of the average cost. The health care resources exploited during hospitalization were analyzed by using an “activity-based costing” method.Results: The Markov model showed that the mean total cost, after an initial increase, tended to remain stable. A total of 20 clinical records were examined. The average daily cost for each patient was EUR 484.42, with a cost for admission of EUR 6781.88.Conclusion: The treatment of HIV infection in compliance with the guidelines is also effective from the payer perspective, as it allows a good health condition to be maintained and reduces the need and the costs of hospitalizations.Keywords: health care cost, HIV, Markov model, activity-based costing

    Full Text Available Introduction: Nucleoside reverse transcriptase inhibitor (NRTI is associated with endothelial dysfunction and proinflammatory effects. Maraviroc (MVC is an antagonist of CCR5 receptor. CCR5 is the receptor of RANTES (Regulated on Activation, Normal T Cell Expressed and Secreted, a mediator of chronic inflammation and endothelial function. Our aim was to evaluate the maintenance of viral suppression and improvement of endothelial function in virologically suppressed HIV-infected patients switched to an NRTI-sparing combined antiretroviral therapy (cART with MVC. Materials and Methods: This observational, non-interventional, multicenter study was performed at the Infectious Diseases Service of Santa Lucia, Morales Meseguer, Virgen de la Arrixaca and Reina Sofía University Hospital (Murcia, Spain. The selection criteria were to be asymptomatic on a regimen with undetectable viral load (<50 HIV-RNA copies/mL for at least six months, no previous treatment with R5 antagonists, no evidence of previous protease inhibitor (PI failure and available R5 tropism test. Twenty-one HIV-infected patients were selected after the treatment regimen was changed to Maraviroc 150 mg/once daily plus ritonavir-boosted PI therapy. Endothelial function was prospectively evaluated through flow-mediated dilatation (FMD of the brachial artery at baseline and at weeks 24. Results: We included 21 patients on treatment with PI in combination with 2 NRTI. The mean cART exposition was 133±68.9 months.

    Full Text Available Background and objective Tenofovir use in HIV positive patients is associated with 0.5–2.5% risk of acute kidney injury (AKI. Data on AKI due to tenofovir use in resource limited settings like India is sparse. Objective of this study is to determine incidence, risk factors and outcome of tenofovir-induced acute kidney injury (serum creatinine>2 mg/dl or creatinine clearance decrease by 50% compared to baseline in HIV infected patients attending tertiary level HIV clinic in Western India. Methods All patients enrolled at the clinic from 2009 to 2012 who were initiated on tenofovir-based ART and had regular follow up creatinine clearance values available were included in this retrospective observational cohort analysis. Patients already on tenofovir-based ART during enrollment were also included. Summary of results 512 patients were enrolled in the study with 70% being males. Average age of the cohort was 41 years, average body weight 56 kilograms and median baseline CD4 count 164 cells/mm3. Mean baseline creatinine clearance was 90 ml/min. Median duration of follow up was 26 months. Tenofovir-induced AKI developed in 25 patients (incidence 4.88 %. Median time to developing AKI was 6 months. On stopping tenofovir, 15 patients had complete recovery of renal function, 5 had partial recovery while 5 patients died. Hemodialysis as a treatment option was used in 3 patients. Age>50 yrs (p=0.001, baseline creatinine clearance<50 ml/min (p=0.0001, diabetes mellitus (p=0.0001, use of tenofovir with protease inhibitors (p=0.001, presence of renal calculus disease (p =0.0001 and use of concomitant nephrotoxic medications (p=0.001 were significantly associated with risk of tenofovir AKI on applying Pearson's Chi square test. Conclusions Incidence of tenofovir-induced AKI in our cohort is higher than previously reported and could be attributed to lower body weight, lower baseline creatinine clearance, higher incidence of advanced HIV disease and higher

    Full Text Available Abstract Background Vitamin D is an important determinant of bone health and also plays a major role in the regulation of the immune system. Interestingly, vitamin D status before the start of highly active antiretroviral therapy (HAART has been recently associated with HIV disease progression and overall mortality in HIV-positive pregnant women. We prospectively studied vitamin D status in HIV individuals on HAART in Belgium. We selected samples from HIV-positive adults starting HAART with a pre-HAART CD4 T-cell count >100 cells/mm3 followed up for at least 12 months without a treatment change. We compared 25-hydroxyvitamin D plasma [25-(OHD] concentration in paired samples before and after 12 months of HAART. 25-(OHD levels are presented using two different cut-offs: Results Vitamin D deficiency was common before HAART, the frequency of plasma 25-(OHD concentrations below 20 ng/ml and 30 below ng/ml was 43.7% and 70.1% respectively. After 12 months on HAART, the frequency increased to 47.1% and 81.6%. HAART for 12 months was associated with a significant decrease of plasma 25-(OHD concentration (p = 0.001. Decreasing plasma 25-(OHD concentration on HAART was associated in the multivariate model with NNRTI-based regimen (p = 0.001 and lower body weight (p = 0.008. Plasma 25-(OHD concentrations decreased significantly in both nevirapine and efavirenz-containing regimens but not in PI-treated patients. Conclusions Vitamin D deficiency is frequent in HIV-positive individuals and NNRTI therapy further decreases 25-(OHD concentrations. Consequently, vitamin D status need to be checked regularly in all HIV-infected patients and vitamin D supplementation should be given when needed.

    Treatment of HIV-infected patients with highly active antiretroviral therapy (HAART) usually results in diminished viral replication, increasing CD4⁺ cell counts, a reversal of most immunological disturbances, and a reduction in risk of morbidity and mortality. However, approximately 20% of all HIV......-infected patients do not achieve optimal immune reconstitution despite suppression of viral replication. These patients are referred to as immunological nonresponders (INRs). INRs present with severely altered immunological functions, including malfunction and diminished production of cells within lymphopoetic...... tissue, perturbed frequencies of immune regulators such as regulatory T cells and Th17 cells, and increased immune activation, immunosenescence, and apoptosis. Importantly, INRs have an increased risk of morbidity and mortality compared to HIV-infected patients with an optimal immune reconstitution...

    Full Text Available The magnitude of intestinal parasitic infection in acquired immunodeficiency syndrome patients requires careful consideration in the developing world where poor nutrition is associated with poor hygiene and several tropical diseases. However, there have been very few studies addressing this issue in Cameroon. This study was conducted to determine the prevalence of intestinal parasitosis in HIV/AIDS patients in Dschang -Cameroon. Stool and blood specimens from HIV/AIDS patients and control group were screened respectively for intestinal parasites and for HIV antibodies. Intestinal parasites were identified using direct microscopy, formalin-ether concentration and Ziehl Neelsen methods. Out of 396 participants recruited among patients consulting at hospital, 42 (10.6% were HIV positive, thirty of them treatment naïve. The overall prevalence of intestinal parasites was 14.64%. Out of 42 HIV/AIDS patients, 59.5% (25/42 were infected with intestinal parasites, while only 9.32% (33/354 of the HIV negative patients were infected with intestinal parasites. The parasites detected in our study population included Crystosporidium parvum (2.53%, Entamoeba histolytica (7.52%, Entamoeba coli (4.04%, Giardia lamblia (0.25%, Trichuris trichura (0.25%, Strongyloides stercoralis (0.25% and Taenia spp. (0.25%. In the HIV infected group, Crystosporidium parvum (19.04%, Entamoeba histolytica (19.04%, Entamoeba coli (21.42%, Giardia lamblia (2.38%, Strongyloides stercoralis (0.25% and Taenia spp. (0.25% were found. Crystosporidium parvum was found to be significantly higher in HIV/AIDS patients than in controls (P<0.05. Multivariate analysis showed that the HIV status and the quality of water were the major risk factors for intestinal parasitosis. Routine examinations of stool samples for parasites would significantly benefit the HIV patients by contributing in reducing morbidity and improving the efficiency of antiretroviral treatment.

    Low response rates and concerns about safety have limited the implementation of treatment for chronic hepatitis C (CHC) in patients with HIV infection. The efficacy and safety of pegylated interferon (peg-IFN) plus ribavirin in HIV-infected patients with CHC were evaluated in a prospective, open-label, multicenter study. Sixty patients with persistently high transaminases, positive HCV-RNA, CD4 count > or = 300 cells/microl, and HIVRNA Patients were given peg-IFN 80-150 microg/week plus ribavirin 800-1200 mg/day. Treatment was scheduled for 24 weeks for genotypes 2/3 and 48 weeks for genotypes 1/4. In an intent- to-treat analysis, 16 (26.7%) patients achieved a sustained virological response (SVR). Twenty patients (33.3%) discontinued treatment prematurely, but only in 10 (16.6%) was discontinuation due to adverse events. Negative predictive values for SVR on the basis of HCV-RNA decline between baseline and week 4 were 100% for 1- and 2-log10 fall, and positive predictive values were 40% and 58.3% for 1- and 2-log10 fall, respectively. CD4 fell by a median of 216 cells during treatment, but no HIV-associated complications occurred. In conclusion, treatment with peg-IFN alpha-2b plus ribavirin is safe and clears RNA-HCV in about one-quarter of HIV-infected patients with CHC. Efforts should be focused on optimizing management of side effects and counseling to improve adherence and to keep patients on treatment. Assessment of HCV-RNA at week 4 may help guide early therapeutic decision making. PMID:16623633

    Full Text Available Abstract Background Highly active antiretroviral therapy (HAART improves the immune function and decreases morbidity, mortality and opportunistic infections (OIs in HIV-infected patients. However, since the use of HAART, immune restoration disease (IRD has been described in association with many OIs. Our objective was to determine the proportion of IRD, changes in CD4+ T-cell count and possible risk factors of IRD in HIV-infected patients. Methods A retrospective study of all HIV- infected patients starting HAART between September 1, 2005 and August 31, 2006 at Zewditu memorial hospital HIV clinic, Addis Ababa, Ethiopia was conducted. All laboratory and clinical data were extracted from computerized clinic records and patient charts. Results A total of 1166 HIV- infected patients with mean ± SD age of 36 ± 9.3 years were on HAART. IRD was identified in 170 (14.6% patients. OIs diagnosed in the IRD patients were tuberculosis (66.5%, 113/170, toxoplasmosis (12.9%, 22/170, herpes zoster rash (12.9%, 22/170, Pneumocystis jirovecii pneumonia (4.1%, 7/170, and cryptococcosis (3.5%, 6/170. Of the 170 patients with IRD, 124 (72.9% patients developed IRD within the first 3 months of HAART initiation. Low baseline CD4+ T-cell count (odds ratio [OR], 3.16, 95% confidence interval [CI], 2.19-4.58 and baseline extra pulmonary tuberculosis (OR, 7.7, 95% CI, 3.36-17.65 were associated with development of IRD. Twenty nine (17.1% of the IRD patients needed to use systemic anti-inflammatory treatment where as 19(11.2% patients required hospitalization associated to the IRD occurrence. There was a total of 8 (4.7% deaths attributable to IRD. Conclusions The proportion and risk factors of IRD and the pattern of OIs mirrored reports from other countries. Close monitoring of patients during the first three months of HAART initiation is important to minimize clinical deterioration related to IRD.

    Full Text Available BACKGROUND: There is paucity of data from India on the impact of HIV related immunosuppression in response to TB treatment and mortality among HIV infected TB patients. We assessed the TB treatment outcome and mortality in a cohort of HIV infected TB patients treated with intermittent short course chemotherapy under TB control programme in a high HIV prevalent district of south India. METHODOLOGY/ FINDINGS: Among 3798 TB patients registered for treatment in Mysore district from July 2007 to June 2008, 281 HIV infected patients formed the study group. The socio-demographic and treatment related data of these patients was obtained from TB and HIV programme records and patient interviews 19 months after TB treatment initiation by field investigators. Treatment success rate of 281 patients was 75% while in smear positive pulmonary tuberculosis cases it was 62%, attributable to defaults (16% and deaths (19%. Only 2 patients had treatment failure. Overall, 83 (30% patients were reported dead; 26 while on treatment and 57 after TB treatment. Association of treatment related factors with treatment outcome and survival status was studied through logistic regression analysis. Factors significantly associated with 'unfavourable outcome' were disease classification as Pulmonary [aOR-1.96, CI (1.02-3.77], type of patient as retreatment [aOR-4.78, CI (2.12-10.76], and non initiation of ART [aOR-4.90, CI (1.85-12.96]. Factors associated with 'Death' were non initiation of ART [aOR-2.80, CI (1.15-6.81] and CPT [aOR-3.46, CI (1.47-8.14]. CONCLUSION: Despite the treatment success of 75% the high mortality (30% in the study group is a matter of concern and needs immediate intervention. Non initiation of ART has emerged as a high risk factor for unfavourable treatment outcome and mortality. These findings underscore the importance of expanding and improving delivery of ART services as a priority and reconsideration of the programme guidelines for ART initiation in

    Full Text Available Toll-like receptor (TLR agonists can reactivate HIV from latently infected cells in vitro. We aimed to investigate the TLR-9 agonist, CPG 7909's in vivo effect on the proviral HIV reservoir and HIV-specific immunity. This was a post-hoc analysis of a double-blind randomized controlled vaccine trial. HIV-infected adults were randomized 1:1 to receive pneumococcal vaccines with or without 1 mg CPG 7909 as adjuvant at 0, 3 and 9 months. In patients on suppressive antiretroviral therapy we quantified proviral DNA at 0, 3, 4, 9, and 10 months (31 subjects in the CPG group and 37 in the placebo-adjuvant group. Furthermore, we measured HIV-specific antibodies, characterized T cell phenotypes and HIV-specific T cell immunity. We observed a mean reduction in proviral DNA in the CPG group of 12.6% (95% CI: -23.6-0.0 following each immunization whereas proviral DNA in the placebo-adjuvant group remained largely unchanged (6.7% increase; 95% CI: -4.2-19.0 after each immunization, p = 0.02. Among participants with additional cryo-preserved PBMCs, HIV-specific CD8+ T cell immunity as indicated by increased expression of degranulation marker CD107a and macrophage inflammatory protein 1β (MIP1β tended to be up-regulated following immunization with CPG 7909 compared with placebo as adjuvant. Further, increasing proportion of HIV-specific CD107a and MIP1β-expressing CD8+ T cells were strongly correlated with decreasing proviral load. No changes were observed in T cell phenotype distribution, HIV-specific CD4+ T cell immunity, or HIV-specific antibodies. TLR9-adjuvanted pneumococcal vaccination decreased proviral load. Reductions in proviral load correlated with increasing levels of HIV specific CD8+ T cells. Further investigation into the potential effect of TLR9 agonists on HIV latency is warranted.

    Full Text Available Abstract Objective To immunophenotype CD4+ and CD8+ T cell sub-populations in HIV-associated immune reconstitution inflammatory syndrome (IRIS. Design Nested case-control immunological study. Methods ART-naïve HIV-infected patients were prospectively observed for IRIS during the first 6 months of ART. Twenty-two IRIS cases and 22 ART-duration matched controls were sampled for T cell immunophenotyping. Results IRIS cases demonstrated significantly lower CD4 cell counts compared to controls (baseline: 79 versus 142, p = 0.02; enrollment: 183 versus 263, p = 0.05, respectively with no differences in HIV RNA levels. Within CD4+T cells, cases exhibited more of an effector memory phenotype compared to controls (40.8 versus 27.0%, p = 0.20, while controls trended towards a central memory phenotype (43.8 versus 30.8%, p = 0.07. Within CD8+ T cells, controls exhibited more central memory (13.9 versus 7.81%, p = 0.01, respectively and effector (13.2 versus 8.8%, p = 0.04, respectively phenotypes compared to cases, whereas cases demonstrated more terminal effectors than controls (28.8 versus 15.1%, p = 0.05. Cases demonstrated increased activation of CD8+ T cell effector memory, terminal effector, and effector subsets than controls (p = 0.04, 0.02, and 0.02, respectively. Conclusion CD4+ and CD8+ T cell subset maturational phenotypes were heterogeneous among IRIS cases and controls. However, IRIS cases demonstrated significant increases in activation of CD8+ T cell effector subpopulations.

    Full Text Available Abstract Objective To evaluate the acceptance and tolerability of the nH1N1 2009 vaccine in HIV-positive individuals. Method 758 patients were included in this prospective study. Different study populations were formed: The Tolerability Study Group consists of HIV-infected patients who visited three outpatient clinics (Cologne, Bonn, Freiburg during a predefined time period. Patients were offered nH1N1 vaccination. Those accepting were administered a standard dose AS03 adjuvant nH1N1 vaccine. Questionnaires to report side effects occurring within 7 days after immunization were handed out. In a substudy conducted during the same time period, acceptance towards immunization was recorded. This Acceptance Study Group consists of all HIV-infected patients visiting the Cologne clinic. They were offered vaccination. In case of refusal, motivation was recorded. Results In the Tolerability Study Group, a total of 475 patient diaries returned in the three study centres could be evaluated, 119 of those (25% reported no side effects. Distribution of symptoms was as follows: Pain 285/475 patients (60%, swelling 96 (20%, redness 54 (11%, fever 48/475 (10%, muscle/joint ache 173 (36%, headache 127 (27%, and fatigue 210 (44%. Association of side effects with clinical data was calculated for patients in Cologne and Bonn. Incidence of side effects was significantly associated with CDC stages A, B compared to C, and with a detectable viral load (> 50 copies/mL. No correlation was noted for CD4 cell count, age, gender or ethnicity. In the Acceptance Study Group, 538 HIV-infected patients were offered vaccination, 402 (75% accepted, while 136 (25% rejected. Main reasons for rejection were: Negative media coverage (35%, indecisiveness with preference to wait until a later date (23%, influenza not seen as personal threat (19% and scepticism towards immunization in general (10%. Conclusion A total of 622 HIV-infected patients were vaccinated against nH1N1-influenza in

    Full Text Available Purpose of the study: One of the most prevalent mental conditions in people with HIV is depression as uniquely characterized by low positive affect. This study examined the effect of a web-based intervention (Avanti on overall mood and depressive symptoms among patients with HIV infection. Methods: Patients treated with effective antiretroviral treatment were included in a two-armed trial with substance abuse as an exclusion criterion and randomized to Avanti (n=36 or control (n=31. Patients were surveyed at baseline, as well as 1 and 3 months after the initiation of a 5-week intervention period. Outcomes were Center for Epidemiological Studies-Depression scale and the Positive and Negative Affect Schedule which was combined into an overall mood index. Changes within groups were tested by Wilcoxon matched pairs test and baseline differences between groups by chi-square and Mann-Whitney independent samples test. Summary of results: Baseline scores for both groups were similar. However, patients in the intervention group had an improvement in median (M overall mood from baseline (M=67.6 to 1 month (M=71, p=0.02 which was also maintained from 1 to 3 months (M=71.9. Moreover, these patients had a favorable reduction in negative affect from 1 (M=24 to 3 months (M=22, p=0.01 and a transient improvement in positive affect from baseline (M=31.7 to 1 month after intervention onset (M=35, p<0.01 which almost returned to baseline levels at month 3 (M=32, p=0.01. In contrast, no significant changes were observed within the control group, except for a reduction in negative affect from 1 (M=23 to 3 months (M=21.6, p=0.05. Notably, symptoms of depression at baseline were low in both the Avanti (M=13 and control (M=12 groups, possibly explaining why no further reduction in depression was observed from baseline to 3 months in either of the two groups. Conclusions: The results of this study lend support to the promise of a web-based psychological intervention

    In a cohort of HIV-infected patients of sub-Saharan origin we describe the incidence of metabolic syndrome, insulin resistance, and lipodystrophy after 3 years of combined antiretroviral therapy, and model the 10-year risk of cardiovascular diseases, while taking into account environmental factors. This is a multinational, prospective cohort study conducted in HIV outpatient clinics from four tertiary care centers set in France and Côte d'Ivoire. The participants were HIV-infected, treatment-naive patients eligible to start antiretroviral treatment and were of sub-Saharan African origin. The main outcome measures were the incidence of metabolic syndrome, insulin resistance, and lipodystrophy, and the assessment of the 10-year risk of cardiovascular diseases using Framingham risk prediction, D.A.D. Cardiovascular Disease Risk, and WHO/ISH prediction charts. Of 245 patients followed for up to 3 years, the incidence of metabolic syndrome, insulin resistance, and lipodystrophy was 5.5, 8.5, and 6.8 per 100 person-years of follow-up (cumulative incidence: 14.4%, 19.2%, and 18.1%, respectively). Living in France as well as female gender and being overweight were risk factors for metabolic disorders as whole and only first generation protease inhibitors were marginally associated with metabolic syndrome. Cardiovascular risk as modeled through the three equations was high in all patients with the synergistic and deleterious effect of living in France compared to Côte d'Ivoire. This cohort study shows how the synergy between HIV, antiretroviral (ARV) exposure, and westernization of life style in a cohort of HIV-infected patients of sub-Saharan origin leads to a progressive increase in the risk of lipodystrophy, as well as metabolic syndrome and insulin resistance, all associated with increased cardiovascular risk.

    Full Text Available Thyroid dysfunction is more common in human immunodeficiency virus (HIV patients. But the effects of highly active antiretroviral therapy (HAART and hepatitis B/C virus (HBV/HCV coinfection on thyroid function is unclear. We retrospectively reviewed the data of 178 HIV patients and determined the prevalence of thyroid dysfunction and the relationship between thyroid hormone levels, CD4 cell count, HIV-1 duration, HAART duration/regimens, and HBV/HCV coinfection. Of the 178 patients, 59 (33.1% had thyroid dysfunction, mostly hypothyroidism. Thyroid dysfunction was significantly more frequent in the HAART group (41/104, 39.4% than in the HAART-naïve group (18/74, 24.3%; P<0.05. The mean CD4 cell count was significantly lower in patients with hypothyroidism (372 ± 331/μL than in the other patients (P<0.05. The FT4 level was significantly lower in the HAART group than in the HAART-naïve group (1.09±0.23 versus 1.20±0.29 pg/mL, P<0.05. FT3/FT4 levels were negatively related to HIV duration and FT3 levels were positively related to CD4 cell (P<0.05. HBV patients had lower FT3 levels, while HCV patients had higher FT3 and FT4 levels (P<0.05. Thyroid dysfunction is more common in HIV patients on HAART, mainly manifested as hypothyroidism. FT3/FT4 levels are correlated with HIV progression. HBV/HCV coinfection increases the probability of thyroid dysfunction.

    The occurrence of intestinal parasites, its relation with the transmission mechanism of HIV, and the clinical state of the AIDS patients, were analyzed in 99 Group IV patients (CDC, 1986), treated at "Hospital Universitário Pedro Ernesto" (HUPE), between 1986 and 1988. The group consisted of 79 (79.8%) patients whose HIV transmission mechanism took place through sexual contact and of 16 (20.2%) who were infected through blood. Feces samples from each patient were examined by four distincts methods (Faust et al., Kato-Katz, Baermann-Moraes and Baxby et al.). The most occurring parasites were: Cryptosporidium sp., Entamoeba coli and Endolimax nana (18.2%), Strongyloides stercoralis and Giardia lamblia (15.2%), E. histolytica and/or E. hartmanni (13.1%), Ascaris lumbricoides (11.1%) and Isospora belli (10.1%). Furthermore, 74.7% of the patients carried at least one species. Intestinal parasites were found in 78.5% of the patients who acquired the HIV through sexual intercourse and in 56.3% of those infected by blood contamination. The difference, was not statistically significant (p greater than 0.05). In the group under study, the increase of the occurrence of parasitic infections does not seem to depend on the acquisition of HIV through sexual contact. It appears that in developing countries, the dependency is more related to the classic mechanisms of parasites transmission and its endemicity. PMID:2487448

    Full Text Available HIV infection has been studied by various sciences, since it articulates biological, clinical and social realities. Since the time of its appearance to the present, advances in the treatment of HIV infection have been notorious and fascinating. Antiretroviral therapy promotes an improved quality of life for patients and increases life expectancy but has had difficulties with treatment associated behaviour, i.e., adherence to treatment. The aim of this study was to evaluate the influence of psychopathological and behavioral determinants of HIV-positive patients. We have found that behavioral risk pattern exists in both genders and predominantely sexual in nature. Men are more compliant than women regarding treatment, but exhibit high levels in the hostility dimension. Indeed, in HIV infection, there's a limited perception of control over disease, which contributes to an adaptation guided by feelings of inadequacy. We underline the vulnerability in the female gender, since women had a behavioral pattern of significant risk.

    Full Text Available Background. The therapeutic goal of antiretroviral therapy (ART is sustained immune recovery and viral suppression. However, some patients experience poor CD4 cell count responses despite achieving viral suppression. Such discordant immune responses have been associated with poor clinical outcomes. Objective. We aimed to determine the prevalence of discordant immune response and explore associated factors in a retrospective cohort of patients attending 2 large public sector clinics, during the 6 months following ART initiation. Methods. Data were analysed from 810 HIV-infected adults initiated on first-line ART at 2 clinics in Johannesburg, between 1 November 2008 and 31 December 2009. Multivariate logistic regression models were used to estimate adjusted odds ratios (AORs to determine associations between discordant immune response and clinical and demographic factors. Results. At ART initiation, 65% (n=592 of participants were female, with a mean age of 38.5 years. Median baseline CD4 cell count was 155 cells/mm3, 70% (n=645 of patients had a haemoglobin level >11 g/dl and 88% (n=803 were initiated on stavudine-lamivudine-efavirenz/nevirapine (D4T-3TC-EFV/NVP. Six months after ART initiation, 24% (n=220 of patients had a discordant immune response and 7% (n=67 a discordant virological response. On multivariate analysis, baseline CD cell count ≥200 cells/mm3 (AOR 3.02; 95% confidence interval (CI 2.08 - 4.38; p<0.001 and moderate anaemia (8.0 - 9.4 g/dl at baseline (AOR 2.30; 95% CI 1.25 - 4.59; p=0.007 were independently associated with the development of discordant immune response, after adjustment for education level, World Health Organization (WHO clinical stage and ART regimen. Conclusions. Discordant immune response following ART initiation was common and associated with baseline anaemia and CD4 cell count in our cohort. Intensive monitoring of at-risk individuals may improve clinical outcomes.

    The initiation of systemic antimicrobial treatment of Pneumocystis jirovecii pneumonia (PCP) is triggered by clinical signs and symptoms, typical radiological and occasionally laboratory findings in patients at risk of this infection. Diagnostic proof by bronchoalveolar lavage should not delay the start of treatment. Most patients with haematological malignancies present with a severe PCP; therefore, antimicrobial therapy should be started intravenously. High-dose trimethoprim/sulfamethoxazole is the treatment of choice. In patients with documented intolerance to this regimen, the preferred alternative is the combination of primaquine plus clindamycin. Treatment success should be first evaluated after 1 week, and in case of clinical non-response, pulmonary CT scan and bronchoalveolar lavage should be repeated to look for secondary or co-infections. Treatment duration typically is 3 weeks and secondary anti-PCP prophylaxis is indicated in all patients thereafter. In patients with critical respiratory failure, non-invasive ventilation is not significantly superior to intubation and mechanical ventilation. The administration of glucocorticoids must be decided on a case-by-case basis. PMID:27550993

    We describe our experience with stent-graft placement in a patient with a clinically diagnosed syphilitic aortic aneurysm.The patient was a 43-year-old man with syphilitic and human immunodeficiency virus (HIV) co-infection. Computed tomography (CT) revealed an aortic aneurysm with 89 mm in maximum size which was located at distal aortic arch and was considered syphilis derived saccular aneurysm. The aneurysm was judged at high risk of rupture from its shape. We decided to perform stent-graft implantation. Before surgery, the patient was given antibacterial and anti-HIV agents. Hand-made fenestrated stent graft by Tokyo Medical University was implanted. The graft was placed from the ascending aorta to Th 9 level in the descending aorta. The aneurysm completely disappeared during follow-up, with no flare-up of syphilitic infection up to 2 years after surgery.The number of patients with syphilis and human immunodeficiency virus co-infection is now increasing. Stent-graft implantation may be an effective treatment in such immunocompromised patients. PMID:23774613

    Full Text Available Background. Nocardiosis is a rare disease that mainly affects severely immunocompromised patients. Symptoms are nonspecific and microbiological isolation is difficult, hiding the diagnosis. Treatment should be guided by species and susceptibility testing. Findings. We report a clinical case of a disseminated nocardiosis in a patient with HIV and HVB infections. Interpretation. Diagnosis should be presumed early and microbiological conditions should be optimized, in order to identify the species and achieve antibiotic susceptibility testing. This is a very important step to choose an effective therapeutic regimen or alternative options.

    HIV/syphilis co-infection is common because both conditions affect similar risk groups. HIV interferes with the natural history of syphilis, which often has atypical clinical features and nervous system involvement in the early stage of disease. We report the case of an HIV-positive patient with secondary syphilis, scaling palmoplantar keratoderma, scrotal eczema, balanitis and urethritis mimicking Reiter's syndrome. Immunohistochemistry using polyclonal antibodies against Treponema pallidum revealed the presence of spirochetes, associated with the paretic form of parenchymal neurosyphilis. The patient was given crystalline penicillin, with complete resolution of dermatological and neurological symptoms, and no sequelae. PMID:26312720

    Introduction Sexually transmitted diseases (STDs) are a major public health issue in Europe. Numerous outbreaks of syphilis have been described recently and an increased prevalence of high-risk sexual practices has raised concern about the transmission of HIV and other STDs. Similarly, an increase in sexually transmitted infections has been recorded in Northern Greece. Methods This report describes a recent outbreak of syphilis in people living with HIV. The demographic, clinical, and serologic data of HIV patients diagnosed with syphilis were recorded and analyzed. Data on syphilis incidence from the general population was also compared to HIV patients’ data. Results Fifty-eight HIV-patients of the Infectious Diseases Unit of a tertiary hospital (5.2%) were diagnosed with syphilis during a three-year period (2008-2010). Highly active antiretroviral therapy (HAART) and coexistence of other STDs were independent predictors of syphilis (OR: 2.4, 95CI%: 1.26, 4.63, p=0.008; OR: 9.4, 95%CI: 4.49, 19.64, pOrigin from a country other than Greece (p=0.005), and homosexual contact (p=0.003), were separate risk factors for syphilis in the general population in the same area. Conclusion Diagnosis of a sexually transmitted disease in an HIV patient is a crucial clinical event that should trigger the clinician’s suspicion for high-risk sexual behavior. Sexual health assessments should be a routine process for HIV patients.

    Full Text Available Background. Pneumocystis pneumonia (PcP is one of the most common opportunistic infections found in patients with HIV. The prognosis if ventilation is required is poor, with mortality of 36 - 80%. Although more recent studies have shown improved survival, our experience has been that close to 100% of such patients die, and we therefore decided to investigate further. Methods. All patients with confirmed or suspected PcP who died owing to respiratory failure were eligible for the study. Where consent was obtained, trucut lung biopsies were performed post mortem, stored in formalin and sent for histopathological assessment. Results. Twelve adequate lung biopsies were obtained from 1 July 2008 to 28 February 2011 – 3 from men and 9 from women. The mean age was 34.7 years (range 24 - 46, and the mean admission CD4 count was 20.8 (range 1 - 68 cells/μl and median 18.5 cells/μl. All specimens demonstrated typical PcP histopathology; in addition, 9 showed significant interstitial fibrosis. Three had co-infection with cytomegalovirus (CMV, two of which had fibrosis present. There was no evidence of TB or other fungal infections. Conclusion. The high mortality seen in this cohort of PcP patients was due to intractable respiratory failure from interstitial lung fibrosis. whereas the differential includes ventilator induced lung injury, drug resistance or co-infections, we suggest that this is part of the disease progression in certain individuals. Further studies are required to identify interventions that could modify this process and improve outcomes in patients with PcP who require mechanical ventilation. S Afr J HIV Med 2012;13(2:64-67.

Methods The clinical data of four HIV-infected PCP and four renal transplantal PCP were analyzed, inclu ding the clinical profiles, immunological status, and chest radiological characteristics. Results Seven of the patients were men, and one was women. The most common clinical symptoms were level', cough without sputum and breathless, and the typical imaging finding was bi lateral diffuse ground glass opacities distributing in perihilar regions. Compared with HIV-infected patients, the number of white blood cell, neumophila and CD4+ T cell were higher in renal tiansplantal patients than that of HIV-infected ones with significant difference. Con clusion More and more PCP happens in HIV-negative patients because of the use of glucocorticoid and immunosuppressive agents. Early diagnosis and timely treatment of TMP-SMZ are important in treating the disease.

    Full Text Available Background: Psychological disorders like depression and anxiety are potentially dangerous conditions. In the context of HIV/AIDS, this can influence health-seeking behavior or uptake of diagnosis and treatment for HIV/AIDS, add to the burden of disease for HIV patients, create difficulty in adherence to treatment, and increase the risk of mortality and morbidity. The objective of this study was to assess the prevalence and correlates of generalized psychological distress among HIV-infected subjects on antiretroviral treatment (ART. Design: An institution-based cross-sectional study was conducted. Interviews were conducted with 500 patients initiating ART at Dilla Referral Hospital. Generalized psychological distress was measured using the Hospital Anxiety and Depression Scale (HADS. A cutoff score ≥19 was used to identify possible cases of patients with generalized psychological distress. Multivariable logistic regression analysis using SPSS Version 20 was performed to identify factors associated with psychological distress. Results: The prevalence of generalized psychological distress among the population of this study was 11.2% (HADS≥19. Factors independently associated with generalized psychological distress were moderate stress (OR=6.87, 95% CI 2.27–20.81, low social support (OR=10.17, 95% CI 2.85–36.29, number of negative life events of six and above (OR=3.99, 95% CI 1.77–8.99, not disclosing HIV status (OR=5.24, 95% CI 1.33–20.62, and CD4 cell count of <200 cells/mm3 (OR=1.98, 95% CI 0.45–0.83 and 200–499 cells/mm3 (OR=3.53, 95% CI 1.62–7.73. Conclusions: This study provides prevalence of psychological distress lower than the prevalence of common mental disorders in Ethiopia and comparable to some other studies in sub-Saharan Africa. The findings are important in terms of their relevance to identifying high-risk groups for generalized psychological distress and preventing distress through integrating mental health

  7. Affective disorders in patients with HIV infection: impact of antiretroviral therapy.

    2006-01-01

    At the beginning of the AIDS pandemic, affective disorders (such as depressed mood) were seen in a considerable number of HIV-1-infected individuals. These disorders were a result of the poor physical condition of the patients, brain involvement by the virus (e.g. encephalopathy) or a reaction to disadvantageous living conditions (losing friends, jobs, etc.). In the era of highly active antiretroviral therapy (HAART), mental illness related to physical weakness is declining, as is the incidence of HIV-1-associated encephalopathy. However, depressed mood and fatigue caused by efavirenz (a standard component of HAART) is becoming increasingly important, particularly in individuals who are infected long-term with HIV-1. Whatever the cause of affective disorders, their presence has been shown to negatively influence adherence to HAART and HIV-1 disease progression. Specialist knowledge of HIV-1 infection, and HAART and its psychiatric complications (particularly in subgroups of patients such as drug abusers and older people), is needed to care adequately for patients. Furthermore, prospective studies are needed to more fully differentiate between the various aetiologies of affective disorders seen in individuals living with HIV/AIDS and to determine their incidence and prevalence. Such information is important to ensure that affective disorders are recognised and adequately treated, which will in turn improve the efficacy of HAART. PMID:16734500

    Although HIV-1 RNA levels are measured at the time of initial diagnosis, the results are not used for the clinical follow-up of the patients. This study evaluates the prognostic value of the baseline HIV-1 RNA levels (above or below 10,000 copies/ml) on rate of disease progression, among antiretroviral therapy (ART)-naive patients in Botswana. A prospective cohort of 436 HIV-infected ART-naive adults with baseline CD4 > 400 cells/mm(3) were followed quarterly for 5 years in an urban clinic in Botswana. Baseline HIV-1 RNA levels and longitudinal CD4(+) T-cell count data were analyzed, using mixed-effects regression jointly modeled with the times to a composite endpoint defined by AIDS-defining clinical conditions or death. During 1,547 person-years (PYs) follow-up time, 106 individuals became eligible for ART initiation (incidence rate: 0.07 PYs) and 6 participants died of AIDS-related illness. There were 203 (47%) individuals with baseline HIV-1 RNA 10,000 copies/ml. The slope of the predicted CD4 trajectory for individuals with baseline HIV-1 RNA >10,000 copies/ml is 30% steeper than that for those with baseline RNA 10,000 copies/ml was 2.3 (95% confidence interval: 1.5-3.0) times higher than that for those with baseline HIV-1 RNA 10,000 copies/ml is much faster than that in those with RNA <10,000. The elevated HIV-1 RNA can be used as a marker to identify individuals at risk of faster disease progression. PMID:26830351

    Conclusions : Medical problems with poor symptom control were the commonest problems, followed by socioeconomic issues related to no income, poor living conditions and fears for the future of their children. Spiritual and psychological issues were surprisingly less of a problem possibly because the immediacy and severity of the demands of day-to-day survival. As a result of the needs identified among these patients, it became apparent that a palliative care ward catering to these needs was needed. The guiding principles in the development of this ward were the need for privacy, for a teamwork approach and for meticulous medical care, all of which underpin good palliative care.

    Full Text Available Introduction: Tuberculosis is difficult to diagnose and it is the leading cause of death in HIV infected individuals in developing countries. There is an urgent need of low-cost diagnostic markers for resource-limited settings. Methods: The study involved 1571 patients from an HIV cohort study in India with known serum albumin concentrations at the time of becoming eligible for antiretroviral therapy (ART. We investigated the diagnostic accuracy of serum albumin to predict tuberculosis within six months of ART eligibility and the prognostic value in patients who experienced tuberculosis. Results: The diagnostic accuracy of serum albumin, measured by the area under the receiver operating characteristic curve, to predict tuberculosis was 0.81 (95% confidence interval 0.78-0.83. Serum albumin concentrations 90%, even in settings with high tuberculosis prevalence. Hypoalbuminemia was associated with an increased risk of mortality in patients with tuberculosis. Conclusion: Serum albumin can be a useful low-cost diagnostic marker for tuberculosis in HIV infected patients eligible for ART. However, we failed to find thresholds to rule out or rule in tuberculosis. If these results are confirmed by other studies, serum albumin could be used to improve the diagnostic accuracy of intensive case finding algorithms for HIV-related tuberculosis. In patients who experience tuberculosis, hypoalbuminemia is associated with poor prognosis.

    Limited information is available on the risk factors for false-negative results with the new generation of QuantiFERON-TB Gold In-Tube (QFT-GIT) tests in non-HIV-infected patients with tuberculosis (TB). We sought to identify risk factors for false-negative QFT-GIT results in culture-confirmed TB patients. We reviewed the microbiological, laboratory, radiographic, and clinical data of 362 patients with positive M. tuberculosis cultures who received QFT-GIT tests at a Korean tertiary hospital between September 2006 and March 2010. Of these, 311 (85.9%) had true-positive and 51 (14.1%) had false-negative results. The false-negative group was more likely to have immunosuppressant diseases and lower platelet, protein, and albumin levels than the true-positive group. An immunosuppressive condition was an independent risk factor for false-negative QFT-GIT results in non-HIV-infected patients with active TB (odds ratio, 2.98; 95% confidence interval, 1.38-6.47; P = .006). Careful interpretation of negative QFT-GIT results is thus necessary in immunocompromised patients suspected of having active TB. PMID:21546200

    Full Text Available Vanishing lung syndrome (VLS is a rare and distinct clinical syndrome that usually affects young men. VLS leads to severe progressive dyspnea and is characterized by extensive, asymmetric, peripheral, and predominantly upper lobe giant lung bullae. Case reports have suggested an additive role of marijuana use in the development of this disease in young male tobacco smokers. We herein report a case of a 65-year-old Hispanic male previously diagnosed with severe emphysema and acquired immune deficiency syndrome (AIDS, with a history of intravenous heroin use and active marijuana smoking who presents to the emergency department with severe progressive shortness of breath he was found to have multiple large subpleural bullae occupying more than one-third of the hemithorax on chest computerized tomography (CT, characteristic of vanishing lung syndrome. The patient was mechanically ventilated and later developed a pneumothorax requiring chest tube placement and referral for surgical bullectomy. Surgical bullectomy has shown high success rates in alleviating the debilitating symptoms and preventing the life threatening complications of this rare syndrome. This case further emphasizes the importance of recognizing VLS in patients with severe emphysema and heavy marijuana smoking.

    Silver nanoparticles (AgNPs) are synthesized using biological sources due to its high specificity in biomedical applications. Herein, we report the size and shape controlled synthesis of AgNPs using the aqueous extract of blue green alga, Spirulina platensis. Size, shape and elemental composition of AgNPs were characterized using UV-vis spectroscopy, Fluorescence spectroscopy, FT-IR (Fourier Transform-Infrared Spectroscopy), FT-RS (Fourier Transform-Raman Spectroscopy), SEM-EDAX (Scanning Electron Microscopy-Energy Dispersive X-ray analysis) and HR-TEM (High Resolution Transmission Electron Microscopy). AgNPs were stable, well defined and monodispersed (spherical) with an average size of 6 nm. The synthesized AgNPs were tested for its antibacterial potency against isolates obtained from HIV patients.

    Full Text Available Introduction: As HIV-infected patients get older more non-AIDS-related malignancies are to be seen. Cancer now represents almost one third of all causes of deaths among HIV-infected patients (1. Albeit bladder cancer is one of the most common malignancy worldwide (2, only 13 cases of bladder cancer in HIV-infected patients have been reported in the literature so far (3. Materials and Methods: We conducted a monocentric study in our hospital. We selected all patients who were previously admitted (from 1998 to 2013 in our hospital with diagnoses of HIV and bladder cancer. The objective was to assess the prevalence and characteristics of bladder cancers in HIV-infected patients in our hospital. Results: Based on our administrative HIV database (6353 patients, we found 15 patients (0.2% with a bladder cancer. Patients’ characteristics are presented in Table 1. Patients were mostly men and heavy smokers. Their median nadir CD4 cell count was below 200 and most had a diagnosis of AIDS. A median time of 14 years was observed in those patients, between the diagnosis of HIV-infection and the occurrence of bladder cancer, although in patients much younger (median age 56 than those developing bladder cancer without HIV infection (71.1 years (4. Haematuria was the most frequent diagnosis circumstance in HIV-infected patients who had relatively preserved immune function on highly active antiretroviral therapy (HAART. Histopathology showed relatively advanced cancers at diagnosis with a high percentage of non transitional cell carcinoma (TCC tumor and of TCC with squamous differentiation, suggesting a potential role for human papilloma virus (HPV co-infection. Death rate was high in this population. Conclusions: Bladder cancers in HIV-infected patients remain rare but occur in relatively young HIV-infected patients with a low CD4 nadir, presenting with haematuria, most of them being smokers, and have aggressive pathological features that are associated with

    The strong CD8+ T-cell-mediated HIV-1-suppressive capacity found in a minority of HIV-infected patients in chronic infection is associated with spontaneous control of viremia. However, it is still unclear whether such capacities were also present earlier in the CD8+ T cells from non controller patients and then lost as a consequence of uncontrolled viral replication. We studied 50 patients with primary HIV-1-infection to determine whether strong CD8+ T-cell-mediated HIV suppression is more often observed at that time. Despite high frequencies of polyfunctional HIV-specific CD8+ T-cells and a strong CD4+ T-helper response, CD8+ T-cells from 48 patients lacked strong HIV-suppressive capacities ex vivo. This indicates that the superior HIV-suppressive capacity of CD8+ T-cells from HIV controllers is not a general characteristic of the HIV-specific CD8+ T cell response in primary HIV infection.

    Full Text Available Objective: To describe the procedures done in children infected with the HIV and to assess the effectiveness of care of the oral cavity by comparison of the levels of Streptococcus mutans and Lactobacillus. Method: Consisted of the sealing of cavities, instructing oral hygiene, supervising and improving the brushing techniques already in use, nutritional counseling for children and their caretakers, and fluoride therapy. Outpatient children from de immunology department of the University Hospital Gafrée e Guinle (UNI-RIO were selected for this study. Children had different levels of immunosupression categorized as severe (50.0%, moderate (33.0% and none (17.0%. Results: The results demonstrated that all children had salivary flow below 0,7ml/min. As for the counting of S. mutans and Lactobacillus, 33.0% kept the same numbers found in the first colonies/ml count. This was due to the presence of radicular remains which constitute an ideal medium for the proliferation of such organisms. There was a decrease in the number of colonies/ml in 67.0% of the children when the second count was made. Conclusion: The procedures carried out were effective in diminishing the number of colonies/ml of S. Mutans and Lactobacilli in the mouths of the target population, thus improving their health. This research intends to present with a protocol description in the odontological care of pediatric patients infected with the HIV and suggests that new studies with a larger population in order to confirm the findings.

    Background HIV infection is a concern in the army troupes because of the risk behaviour of the military population. In order to allow regular access to CD4+ T cell enumeration of military personnel as well as their dependents and civilians living with HIV, the Senegalese Army AIDS program is implementing PIMATM Alere technology in urban and semi-urban military medical centres. Validation such device is therefore required prior their wide implementation. The purpose of this study was to compare CD4+ T cell count measurements between the PIMATM Alere to the BD FACSCountTM. Methodology We selected a total of 200 subjects including 50 patients with CD4+ T-cells below 200/mm3, 50 between 200 and 350/mm3, 50 between 351 and 500/mm3, and 50 above 500/mm3. CD4+ T-cell count was performed on venous blood using the BD FASCountTM as reference method and the PIMATM Point of Care technology. The mean biases and limits of agreement between the PIMATM Alere and BD FACSCountTM were assessed with the Bland-Altman analysis, the linear regression performed using the Passing-Bablok regression analysis, and the percent similarity calculated using the Scott method. Results Our data have shown a mean difference of 22.3 cells/mm3 [95%CI:9.1–35.5] between the BD FACSCountTM and PIMATM Alere CD4 measurements. However, the mean differences of the two methods was not significantly different to zero when CD4+ T-cell count was below 350/mm3 (P = 0.76). The Passing-Bablok regression in categorized CD4 counts has also showed concordance correlation coefficient of 0.89 for CD4+ T cell counts below 350/mm3 whilst it was 0.5 when CD4 was above 350/mm3. Conclusion Overall, our data have shown that for low CD4 counts, the results from the PIMATM Alere provided accurate CD4+ T cell counts with a good agreement compared to the FACSCountTM.

    Full Text Available From 1986 to 1999, 2460 HIV-positive inpatients were seen in our Hospital. Neurological abnormalities were detected in 1053 (42.8% patients. In this group, 28 (2.7% had involuntary movements, 14 (50% with secondary parkinsonism, six (21.4% with hemichorea/hemiballismus, four (14.2% with myoclonus, two (7.2% with painful legs and moving toes, one (3.6% with hemidystonia and one (3.6% with Holmes' tremor. The HIV itself (12 patients, toxoplasmosis of the midbrain (1 and metoclopramide-related symptoms (1 were the most probable causes for the parkinsonism. All patients with hemichorea/hemiballismus were men and in all of them toxoplasmosis of the basal ganglia, mostly on the right side, was the cause of the involuntary movements. Generalized myoclonus was seen in two patients and they were due to toxoplasmosis and HIV-encephalopathy respectively; two others presented with spinal myoclonus. The two patients with painful legs and moving toes had an axonal neuropathy. The patient with hemidystonia suffered from toxoplasmosis in the basal ganglia and the patient with Holmes' tremor had co-infection with tuberculosis and toxoplasmosis affecting the midbrain and cerebellum. We conclude that HIV-infected patients can present almost any movement disorder. They can be related to opportunistic infections, medications, mass lesions and possibly to a direct or indirect effect of the HIV itself.De 1986 a 1999, 2460 pacientes HIV-positivos internados foram avaliados em nosso Hospital.

Recent advanced technologies of high-throughput sequencing and bioinformatics allow researchers to explore nonculturable microbes including bacteria, virus and fungi and their association with diseases. HIV/SIV infection is associated with microbiome shifts and immune activation that may affect the outcome of disease progression. Similarly, altered microbiome and inflammatio...

    OBJECTIVES: In the case of coinfection with HIV and hepatitis B virus (HBV) and/or hepatitis C virus (HCV), hepatic disease progression is often accelerated, with higher rates of liver cirrhosis and liver-related mortality. We aimed to evaluate the performance of the rapid tests used routinely to...... detect HBV surface antigen (HBsAg) and anti-HCV among HIV-infected patients in Guinea-Bissau. METHODS: Blood samples from HIV-infected patients in Guinea-Bissau were stored after testing for HBsAg and anti-HCV with rapid tests. Samples were subsequently re-tested for HBsAg and anti-HCV in Denmark....... RESULTS: Two rapid tests were used in Guinea-Bissau: HBsAg Strip Ref 2034 (VEDA.LAB, Alençon, France; sensitivity 62.3%; specificity 99.2%) and HEPA-SCAN (Bhat Bio-Tech, Bangalore, India; sensitivity 57.1%; specificity 99.7%). In the two tests the ability to obtain the correct outcome depended on the...

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

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available With the introduction of combined active antiretroviral therapy and the improved survival of HIV-infected patients, degenerative diseases and drug toxicity have emerged as long-term concerns. We studied the prevalence of decreased glomerular filtration rate (GFR and associated risk factors in a cohort of HIV-infected patients from a middle-income country. Our cross-sectional study included all adult patients who attended an urban outpatient clinic in 2008. GFR was estimated using the CKD-EPI equation. The prevalence ratio (PR of decreased GFR (defined as <60 mL/min/1.73 m(2 was estimated using generalizing linear models assuming a Poisson distribution. We analyzed data from 1,970 patients, of which 82.9% had been exposed to ART. A total of 249 patients (12.6% had a GFR between 60 and 89 mL/min/1.73 m(2, 3.1% had a GFR between 30 and 59, 0.3% had a GFR between 15 and 29, and 0.4% had a GFR <15. Decreased GFR was found in only 74 patients (3.8%. In the multivariate regression model, the factors that were independently associated with a GFR below 60 mL/min/1.73 m(2 were as follows: age ≥ 50 years (PR = 3.4; 95% CI: 1.7-6.8, diabetes (PR = 2.0; 95% CI: 1.2-3.4, hypertension (PR = 2.0; 95% CI: 1.3-3.2, current CD4+ cell count <350 cells/mm3 (PR = 2.1; 95% CI: 1.3-3.3, past exposure to tenofovir (PR = 4.7; 95% CI: 2.3-9.4 and past exposure to indinavir (PR =1.7; 95% CI: 1.0-2.8. As in high-income countries, CKD was the predominant form of kidney involvement among HIV-infected individuals in our setting. The risk factors associated with decreased glomerular filtration were broad and included virus-related factors as well as degenerative and nephrotoxic factors. Despite the potential for nephrotoxicity associated with some antiretroviral drugs, in the short-term, advanced chronic renal disease remains very rare.

    Full Text Available The incidence of hepatotoxicity related to trimethoprim/sulfamethoxazole (TMP/SMX administered at a therapeutic dose may vary among study populations of different ethnicities and hepatotoxic metabolites of TMP/SMX may be decreased by drug-drug interaction with fluconazole. We aimed to investigate the incidence of hepatotoxicity and the role of concomitant use of fluconazole in HIV-infected patients receiving TMP/SMX for Pneumocystis jirovecii pneumonia. We reviewed medical records to collect clinical characteristics and laboratory data of HIV-infected patients who received TMP/SMX for treatment of P. jirovecii pneumonia at 6 hospitals around Taiwan between September 2009 and February 2013. Hepatotoxicity was defined as 2-fold or greater increase of aminotransferase or total bilirubin level from baselines. Roussel UCLAF Causality Assessment Method (RUCAM was used to analyze the causality of drug-induced liver injuries. NAT1 and NAT2 acetylator types were determined with the use of polymerase-chain-reaction (PCR restriction fragment length polymorphism to differentiate common single-nucleotide polymorphisms (SNPs predictive of the acetylator phenotypes in a subgroup of patients. During the study period, 286 courses of TMP/SMX treatment administered to 284 patients were analyzed. One hundred and fifty-two patients (53.1% developed hepatotoxicity, and TMP/SMX was considered causative in 47 (16.4% who had a RUCAM score of 6 or greater. In multivariate analysis, concomitant use of fluconazole for candidiasis was the only factor associated with reduced risk for hepatotoxicity (adjusted odds ratio, 0.372; 95% confidence interval, 0.145-0.957, while serostatus of hepatitis B or C virus, NAT1 and NAT2 acetylator types, or receipt of combination antiretroviral therapy was not.

  15. Utility of FDG-PETCT and magnetic resonance spectroscopy in differentiating between cerebral lymphoma and non-malignant CNS lesions in HIV-infected patients

    International Nuclear Information System (INIS)

    Background and purpose: In HIV infected patients, MRI cannot reliably differentiate between central nervous system (CNS) lymphoma and non-malignant CNS lesions, particularly cerebral toxoplasmosis (CTOX). This study prospectively investigates the utility of FDG PET-CT and magnetic resonance spectroscopy (MRS) in discriminating CNS lymphoma from non-malignant CNS lesions in HIV infected patients, and assesses the ability of FDG PET-CT to guide the use of early brain biopsy. Methods: 10 HIV patients with neurological symptoms and contrast enhancing lesions on MRI were commenced on anti-toxoplasmosis therapy before undergoing FDG PET-CT and MRS. Brain biopsies were sought in those with FDG PET-CT suggestive of CNS lymphoma, and in those with a negative FDG PET-CT scan who failed to respond to therapy. Final diagnosis was based on histology or treatment response. Results: Two patients were confirmed to have CNS lymphoma and FDG PET-CT was consistent with this diagnosis in both. Six patients had cerebral toxoplasmosis in all of whom FDG PET-CT was consistent with non-malignant disease. One patient had progressive multifocal leukoencephalopathy (PML), FDG PET-CT was equivocal. One patient had a haemorrhagic brain metastasis and FDG PET-CT wrongly suggested non-malignant disease. MRS was performed successfully in eight subjects: three results were suggestive of CNS lymphoma (one true positive, two false positive), four suggested CTOX (two false negative, two true negative), one scan was equivocal. Conclusion: FDG PET-CT correctly identified all cases of CNS lymphoma and CTOX, supporting its use in this situation. MRS was unhelpful in our cohort

    Full Text Available Introduction. TLR´s play a role in host defense in HIV infection recognizing the viral DNA or RNA. Their activation induces a signaling pathway that includes the proteins MyD88, IRAK4, TRAF6 and the transcription factor NF-kBp65. Objective. To determine the expression of TLR7, TLR8 and TLR9, and activation of its signaling pathway in monocytes from patients infected with HIV. Methods. Expression of TLR7, TLR8 and TLR9 was determined in monocytes from HIV-infected patients (n = 13 and control subjects (n = 13, which were activated with specific ligands. The expression of MyD88 and NF-kBp65 were determined by flow cytometry; IRAK4 and TRAF6 were studied by immunoblotting. Results. No statistical difference was found in the expression of TLR7, 8 and 9 in monocytes from patients compared to controls, but we observed the non-significant increased expression of TLR9 in patients. The activation showed no significant difference in the expression of MyD88 and NF-kBp65 in patients when compared to controls, but were decreased in stimulated cells over non-stimulated cells. IRAK4 and TRAF6 were not detected. Conclusions. No statistical difference was observed in the expression of intracellular TLRs, MyD88 and NFkBp65 in monocytes from patients compared to controls. This was probably due to effective antiretroviral therapy being received at the time of study entry. Additional studies are needed (ARTV under controlled conditions that include infected patients with and without ARVT, responders and non- responders, and work with different cell populations

    2016-01-01

    Objective: Several pieces of evidence indicate that HIV-infected adults undergo premature aging. The effect of HIV and antiretroviral therapy (ART) exposure on the aging process of HIV-infected children may be more deleterious since their immune system coevolves from birth with HIV. Design: Seventy-one HIV-infected (HIV+), 65 HIV-exposed-uninfected (HEU), and 56 HIV-unexposed-uninfected (HUU) children, all aged 0–5 years, were studied for biological aging and immune senescence. Methods: Telomere length and T-cell receptor rearrangement excision circle levels were quantified in peripheral blood cells by real-time PCR. CD4+ and CD8+ cells were analysed for differentiation, senescence, and activation/exhaustion markers by flow cytometry. Results: Telomere lengths were significantly shorter in HIV+ than in HEU and HUU children (overall, P < 0.001 adjusted for age); HIV+ ART-naive (42%) children had shorter telomere length compared with children on ART (P = 0.003 adjusted for age). T-cell receptor rearrangement excision circle levels and CD8+ recent thymic emigrant cells (CD45RA+CD31+) were significantly lower in the HIV+ than in control groups (overall, P = 0.025 and P = 0.005, respectively). Percentages of senescent (CD28−CD57+), activated (CD38+HLA-DR+), and exhausted (PD1+) CD8+ cells were significantly higher in HIV+ than in HEU and HUU children (P = 0.004, P < 0.001, and P < 0.001, respectively). Within the CD4+ cell subset, the percentage of senescent cells did not differ between HIV+ and controls, but programmed cell death receptor-1 expression was upregulated in the former. Conclusions: HIV-infected children exhibit premature biological aging with accelerated immune senescence, which particularly affects the CD8+ cell subset. HIV infection per se seems to influence the aging process, rather than exposure to ART for prophylaxis or treatment. PMID:26990630

    Full Text Available OBJECTIVE: We investigated the relationship of the Herpesviridiae with inflammation and subclinical atherosclerosis in HIV-infected patients. METHODS: Prospective study including virologically suppressed HIV-infected patients. IgG antibodies against herpesviruses, carotid intima-media thickness (cIMT, endothelial function through flow-mediated dilatation (FMD of the brachial artery, and blood atherosclerosis biomarkers (hsCRP, TNF-α, IL-6, MCP-1, MDA, sCD14, sCD163, VCAM-1, ICAM-1, D-dimer, and PAI-1 were measured. RESULTS: 136 patients with HIV viral load <200 copies/ml were included. 93.4% patients were infected with herpes simplex virus type-1, 55.9% with herpes simplex virus type-2, 97.1% with varicella-zoster virus, 65.4% with human herpesvirus-6, 91.2% with cytomegalovirus, and 99.3% with Epstein-Barr virus. Previous AIDS diagnosis was associated with higher cytomegalovirus IgG titers (23,000 vs 17,000 AU, P = 0.011 and higher varicella-zoster virus IgG titers (3.19 vs 2.88 AU, P = 0.047, and there was a positive correlation of the Framingham risk score with IgG levels against cytomegalovirus (Spearman's Rho 0.216, P = 0.016 and Herpes simplex virus-2 (Spearman's Rho 0.293, P = 0.001. IgG antibodies against cytomegalovirus correlated in adjusted analysis with the cIMT (P = 0.030. High seropositivity for varicella-zoster virus (OR 2.91, 95% CI 1.05-8.01, P = 0.039, and for cytomegalovirus (OR 3.79, 95% CI 1.20-11.97, P = 0.023 were predictors for the highest quartile of the cIMT in adjusted analyses. PAI-1 levels were independently associated with cytomegalovirus IgG titers (P = 0.041, IL-6 and ICAM-1 levels with varicella-zoster virus IgG (P = 0.046 and P = 0.035 respectively, and hsCRP levels with Herpes simplex virus-2 IgG (P = 0.035. CONCLUSION: In virologically suppressed HIV-infected patients, antibody responses against herpesviruses are associated with subclinical atherosclerosis, and with increased inflammation and coagulation

    We analysed the efficacy and safety of switching from a regimen based on nonnucleoside reverse transcriptase inhibitors (NNRTI) or integrase inhibitors (INI) to ABC/3TC + RPV in virologically suppressed HIV-infected patients. This multicentre, retrospective study comprised asymptomatic HIV-infected patients who switched from 2 NRTI + NNRTI or 2 NRTI + INI to ABC/3TC + RPV between February 2013 and December 2013; all had undetectable HIV viral load prior to switching. Efficacy and safety, and changes in lipids and cardiovascular risk (CVR) were analysed at 48 weeks. Of 85 patients (74.1 % men, mean age 49.5 years), 83 (97.6 %) switched from a regimen based on NNRTI (EFV 74, RPV 5, ETV 2, NVP 2), and 45 (53 %) switched from TDF/FTC to ABC/3TC. The main reasons for switching were toxicity (58.8 %) and convenience (29.4 %). At 48 weeks, 78 (91.8 %) patients continued taking the same regimen; efficacy was 88 % by intention to treat, and 96 % by per protocol. Two patients were lost to follow-up and five ceased the new regimen (4 due to adverse effects and 1 virologic failure). Mean CD4 cell counts increased (744 vs. 885 cells/μL; p = 0.0001), and there were mean decreases in fasting total cholesterol (-15.9 mg/dL; p < 0.0001) and LDL-cholesterol (-11.0 mg/dL; p < 0.004), with no changes in HDL-cholesterol, triglycerides, total cholesterol:HDL-cholesterol ratio, and CVR. ABC/3TC + RPV is effective and safe in virologically-suppressed patients on antiretroviral therapy (ART). Forty-eight weeks after switching the lipid profile improved with decreases in total and LDL cholesterol. PMID:26879392

    This thesis is based on seven previously published articles. The work was performed during my employment at The Department of Infectious Diseases, Copenhagen University Hospital, Hvidovre, as a scholarship student from 2000-2001 and as a research assistant in the period 2004-2010. HIV-infection is characterized by CD4+ cell depletion. The differences between patients in the degree of CD4+ cell recovery upon treatment with highly active antiretroviral therapy (HAART) may in part be due to differences in the supply of naïve CD4+ cells from the thymus. The thymus atrophies with increasing age for which reason the adult thymus was previously assumed to be without function. The aim of these investigations was to examine the role of the thymus in different aspects of HIV-infection: In adult HIV-infected patients, during HIV-positive pregnancy, and in HIV-exposed uninfected (HIV-EU) children born to HIV-infected mothers. Thymic size and output were determined in 25 adult HIV-infected patients receiving HAART and in 10 controls. Larger thymic size was associated with higher CD4 counts and higher thymic output. Furthermore, patients with abundant thymic tissue seemed to have broader immunological repertoires, compared with patients with minimal thymic tissue. The study supports the mounting evidence of a contribution by the adult thymus to immune reconstitution in HIV-infection. In a follow-up study conducted till 5 years of HAART, the importance of the thymus to the rate of cellular restoration was found to primarily lie within the first two years of HAART. The effect of recombinant human growth hormone (rhGH) was then investigated in a randomized, double-blinded placebo controlled trial in 46 adult HIV-infected patients on HAART. Daily treatment with a low dose of rhGH of 0.7mg for 40 weeks stimulated thymopoiesis as expressed by thymic size, density, and output strongly supporting the assumption that rhGH possesses the potential to stimulate the ageing thymus, holding

    Full Text Available Objectives: A cross-sectional study on prevalence of HBV and HDV infection, risk factors and genotype distribution of HBV infection was conducted among 848 HIV-infected patients in Mato Grosso do Sul, Central Brazil. Methods: Serum samples of 848 participants were tested for hepatitis B surface antigen (HBsAg, hepatitis B core antibody (anti-HBc and hepatitis surface antibody (anti-HBs. HBsAg positive samples were tested for anti-HBc IgM, HBeAg, anti-HBe, anti-HCV, and total anti-HDV. HBsAg and anti-HBc positive were subjected to DNA extraction. Viral DNA was amplified by semi-nested PCR for the regions pre-S/S and then purified and genotyped/subgenotyped by direct sequencing. Student's t-test, chi-square test and Fisher's exact test were used to compare variables and to evaluate association between HBV positivity (defined as anti-HBc and/or HBsAg positivity and risk factors. Results: Among the 848 HIV infected patients investigated 222 had serological markers of HBV infection. The prevalence rate of HIV-HBV coinfection was 2.5% (21/848; 95% CI: 1.4–3.5%; 484 (57.1% patients were susceptible for HBV infection. There were no cases of anti-HDV positive and only one (0.1% anti-HCV-positive case among the HIV-HBV coinfected patients. Male gender, increasing age, family history of hepatitis, use of illicit drug, and homosexual activity were independent factors associated with HBV exposure. The phylogenetic analysis based on the S gene region revealed the presence of genotypes D (76.9%, F (15.4% and A (7.7% in the study sample. Conclusion: This study demonstrates the low prevalence of HIV-HBV infection and also highlights the need for early vaccination against HBV as well as testing for HBV, HCV and HDV in all HIV-infected individuals.

    Strategies to develop a functional cure for HIV infection will likely require boosting of effector T cell responses to eliminate reactivated, latently infected cells. We have recently explored an assay for assessing antigen-specific regulation of T cell proliferation, which was related to clinical progression in untreated patients and to vaccine efficacy in two trials of therapeutic Gag-based vaccines. We here expand the same assay to further investigate regulation mediated by various inhibitory pathways. Peripheral blood mononuclear cells from 26 asymptomatic HIV-infected, antiretroviral therapy-naïve patients were stimulated with Gag and Env overlapping peptide panels for 5 days. Monoclonal antibodies (mAbs) blocking inhibitory mediators interleukin (IL) 10, transforming growth factor (TGF) β, programmed death ligand (PD–L) 1 and herpes virus entry mediator (HVEM) were added to parallel cultures. Functional T cell regulation (FTR) was defined as the difference in proliferation between stimulated cultures with and without blocking mAbs. FTR was detected in 54% of patients. Blockade of IL-10/PD-L1 and IL10/TGF-β detected all cases with Gag- and Env-associated FTR, respectively. In accordance with previous findings, isolated Env FTR was associated with higher plasma HIV RNA and lower CD4 counts, while patients with both Gag and Env FTR also had higher Gag- and Env-specific proliferative CD8+ T cell responses. There was no association between FTR and frequencies of activated regulatory T cells. In conclusion, we observed substantial heterogeneity in FTR between patients, inhibitory pathways and HIV antigens. FTR may help to individualize immunomodulation and warrants further assessment in clinical immunotherapy trials. PMID:27128502

    Full Text Available BACKGROUND: Progressive resistance exercise training (PRT improves physical functioning in patients with HIV infection. Creatine supplementation can augment the benefits derived from training in athletes and improve muscle function in patients with muscle wasting. The objective of this study was to determine whether creatine supplementation augments the effects of PRT on muscle strength, energetics, and body composition in HIV-infected patients. METHODOLOGY/PRINCIPAL FINDINGS: This is a randomized, double blind, placebo-controlled, clinical research center-based, outpatient study in San Francisco. 40 HIV-positive men (20 creatine, 20 placebo enrolled in a 14-week study. Subjects were randomly assigned to receive creatine monohydrate or placebo for 14 weeks. Treatment began with a loading dose of 20 g/day or an equivalent number of placebo capsules for 5 days, followed by maintenance dosing of 4.8 g/day or placebo. Beginning at week 2 and continuing to week 14, all subjects underwent thrice-weekly supervised resistance exercise while continuing on the assigned study medication (with repeated 6-week cycles of loading and maintenance. The main outcome measurements included muscle strength (one repetition maximum, energetics ((31P magnetic resonance spectroscopy, composition and size (magnetic resonance imaging, as well as total body composition (dual-energy X-ray absorptiometry. Thirty-three subjects completed the study (17 creatine, 16 placebo. Strength increased in all 8 muscle groups studied following PRT, but this increase was not augmented by creatine supplementation (average increase 44 vs. 42%, difference 2%, 95% CI -9.5% to 13.9% in creatine and placebo, respectively. There were no differences between groups in changes in muscle energetics. Thigh muscle cross-sectional area increased following resistance exercise, with no additive effect of creatine. Lean body mass (LBM increased to a significantly greater extent with creatine. CONCLUSIONS

    Full Text Available A patient with HIV infection developed the first episode of AIDS-defining opportunism (severe Candida albicans esophagitis with an underlying CD4+ lymphocyte count of 1,025 cells/µL. After treatment with a highly active antiretroviral therapy (HAART, taken with insufficient compliance and leaving a residual viral load, our patient suffered from two relapses of esophageal candidiasis, which occurred three months and seven years later, when his CD4+ lymphocyte count was 930 and 439 cells/µL, respectively, and a viral load slightly above 10(4 copies/mL was still present. Also in the HAART era, Candida esophagitis remains one of the most common AIDS-defining diseases, but a presentation with a concurrent CD4+ count above 1,000 cells/µL remains a rare exception, as well as the two isolated, subsequent relapses, occurred with a CD4+ count ranging from 439 to 930 cells/µL, and a residual HIV viremia due to insufficient adherence to the prescribed HAART regimens. Our case report represents the opportunity to revisit the epidemiology and, especially, the pathogenesis of this opportunistic fungal complication in HIV-infected patients and in other subjects at risk, on the ground of an extensive literature review, and to explore possible alternative supporting factors other than the crude absolute CD4+ lymphocyte count, with emphasis on the possible role of a persisting HIV viremia, and other potential contributing factors. Clinicians engaged with immunocompromised patients and subjects with HIV disease, should be aware that a Candida esophagitis may occur and relapse also when the cell-mediated immunity, as measured by a simple CD4+ cell count, do not show relevant abnormalities.

    Full Text Available Abstract Background East Africa has experienced a rapid expansion in access to antiretroviral therapy (ART for HIV-infected patients. Regionally representative socio-demographic, laboratory and clinical characteristics of patients accessing ART over time and across sites have not been well described. Methods We conducted a cross-sectional analysis of characteristics of HIV-infected adults initiating ART between 2002 and 2009 in Kenya, Uganda and Tanzania and in the International Epidemiologic Databases to Evaluate AIDS Consortium. Characteristics associated with advanced disease (defined as either a CD4 cell count level of less than 50 cells/mm3 or a WHO Stage 4 condition at the time of ART initiation and use of stavudine (D4T or nevirapine (NVP were identified using a log-link Poisson model with robust standard errors. Results Among 48, 658 patients (69% from Kenya, 22% from Uganda and 9% from Tanzania accessing ART at 30 clinic sites, the median age at the time of ART initiation was 37 years (IQR: 31-43 and 65% were women. Pre-therapy CD4 counts rose from 87 cells/mm3 (IQR: 26-161 in 2002-03 to 154 cells/mm3 (IQR: 71-233 in 2008-09 (p Conclusions Public health ART services in east Africa have improved over time, but the fraction of patients accessing ART with advanced immunosuppression is still high, men consistently access ART with more advanced disease, and D4T continues to be common in most settings. Strategies to facilitate access to ART, overcome barriers among men and reduce D4T use are needed.

    Current management of HIV involves the use of conventional prescription medicines, called 'antiretroviral drugs' (ARV), over-the-counter (OTC), complementary and alternative medicines (CAM), as well as African traditional medicine (ATM). The aim of this study was to determine the prevalence of use of traditional, complementary and over-the-counter medicines. A cross-sectional survey of HIV-infected patients who started ART between July 2004 and August 2005 at Dr George Mukhari Hospital (Pretoria), who consented to be interviewed, was conducted. Using a pre-tested structured questionnaire, data were collected by two trained interviewers on sociodemographic characteristics, and on non-prescribed medicines used of three sources: African traditional medicine (ATM), complementary and alternative medicine (CAM), and over-the-counter (OTC) medicines. The 180 patients who consented to be interviewed had a mean age of 36.7 (+/-8.1) years old; 68.8% were female, 86.7% unemployed, 73.9% with high school level of education, 77.8% single. Some 8.9% of respondents used at least one non-prescribed medicine. In descending order, 4.4% of respondents used ATM, 3.3% CAM, and 1.7% OTC medicines. The ATM products used included unspecified traditional mixtures, and those made of the African potato (Hypoxis hemerocallidea), and coconut (Cocos nucifera); OTC products used were paracetamol and sennosides (Senokot) tablets as well as a soap containing triclosan 1.5%; CAM products used were "sex booster" capsules of unknown composition, mercury-containing soaps (Mekako), and the Zion Church of Christ special tea, a mixture of Rooibos tea (Aspalathus linearis) plus sunflower oil (Helianthus annuus) and prayed for. In conclusion, only 8.9% of HIV-infected patients on ART in this study used a limited range of over-the-counter products as well as those from traditional, complementary and alternative medicine practices.

    Continuous HIV treatment is necessary to ensure successful combined antiretroviral therapy (cART). The aim of this study was to evaluate the incidence of patient-initiated non-structured treatment interruptions in HIV-infected persons who inject drugs and who received a multidisciplinary comprehensive program, including medical HIV care, drug-dependence treatment and psychosocial support, at a drug outpatient addiction center. Non-structured treatment interruptions were defined as ≥30 consecutive days off cART without medical indication. During a median follow-up of 53.8 months, 37/132 (28 %) patients experienced the first non-structured treatment interruptions. The cumulative probability of cART interruption at 5 years was 31.2 % (95 % CI 22.4-40.0). Current drug use injection ≥1/day (HR 14.77; 95 % CI 5.90-36.96) and cART naive patients (HR 0.35, 95 % CI 0.14-0.93) were predictive factors for non-structured treatment interruptions. HIV care provided at a drug addiction center is a useful strategy to sustain continuous cART, however, drug abstinence is essential for the long-term maintenance of cART. PMID:26427376

    IRIS is described as a paradoxical deterioration of clinical status upon initiation of combined anti-retroviral therapy (cART) in patients with HIV infection. Immune reconstitution inflammatory syndrome (CNS-IRIS) involving the central nervous system is rarely reported. We describe the case of 57-year-old man who developed a fatal case of CNS- IRIS. A rapid deterioration of neurological status was associated with progression of patchy T2-weighted hyperintensities involving different vascular territories on brain MRI. Diagnosis of CNS-IRIS is based of laboratory and radiologic findings, however brain biopsy is supportive. Despite immune restoration being involved in clinical deterioration, discontinuation of cART is not recommended. The use of corticosteroids is highly controversial. Prompt recognition of CNS-IRIS is crucial for preventing neurological complications and ensuing sequelae. PMID:23435821

    Background The HIV epidemic poses significant challenges to the low income countries in sub Saharan Africa (SSA), affecting the attrition rate among health care workers, their level of motivation, and absenteeism from work. Little is known about how to deal with deterioration of human resources in the health care systems. This study aimed to predict the intention to provide surgical treatment to HIV infected patients among medical- and dental students in Tanzania and Sudan using an extended version of the Theory of Planned Behaviour (TPB). Methods Four hundred and seventy five medical- and dental students at the University of Dar es Salaam (mean age, 25 yr) and 642 dental students attending 6 public and private dental faculties in Khartoum (mean age 21.7 yr) completed self-administered TPB questionnaires in 2005 and 2007, respectively. Results Both Tanzanian and Sudanese students demonstrated strong intentions to provide care for people with HIV and AIDS. Stepwise linear regression revealed that the TPB accounted for 51% (43% in Tanzania and Sudan) of the variance in intention across study sites. After having controlled for country and past behaviour, the TPB in terms of attitudes, subjective norms and perceived behavioural control accounted for 34% and moral norms for an additional 2,3% of the explainable variance in intention. Across both study sites, attitudes were the strongest predictor of intention followed in descending order by subjective norms, moral norms and perceived behavioural control. Conclusion The TPB is applicable to students' care delivery intentions in the context of HIV and AIDS across the two SSA countries investigated. It is suggested that attitudes, subjective norms, moral norms and perceived behavioural control are key factors in students' willingness to treat AIDS and HIV infected patients and should be targets of interventions aimed at improving the quality of health care delivery in this context.

    Full Text Available Introduction: Little is known about the well-being on long-term exposure to antiretroviral therapy. The ACTG Augmented Symptoms Distress Module (ASDM is a validated tool which measures the presence of a total of 22 symptoms seen with HIV and quantifies the extent to which they cause distress to the patient. Methods: ELBE was a cross-sectional study that consecutively included adult HIV-infected patients presenting with viral suppression (<50 HIV RNA copies/mL and ART exposure for at least five years. Patients were evaluated by four different questionnaires, including ASDM. Results: Of a total of 894 patients included in the three participating ELBE centres, complete data on ASDM were available for 698 patients (626 male, 69 female, 3 transsexual. Median age was 49.7 years (range, 23.3–82.5 years and median exposure to ART was 11.5 years (range, 5–28 years. Median CD4 T-cell counts had increased from a CD4 nadir of 180 to currently 640 cells/µL. Despite immunological and virological success, a high degree of symptom-related distress was noted in this patient population. In total, 63.8% and 36.3% of the patients had at least one “bothersome” or one “very bothersome” symptom, respectively. The symptoms most frequently reported to be “bothersome” or “very bothersome” were fatigue and energy loss (18.5% and 11.0% respectively, insomnia (12.8% and 11.6%, sadness and depression (13.0% and 10.0%, sexual dysfunction (12.0% and 10.0%, and changes in body appearance (11.0% and 10.9%. There was no association between the degree of symptom-related distress and gender, age or CD4 T-cell nadir. However, the history of AIDS-defining illnesses, comorbidities such as depression but also the duration of ART were significantly associated with a higher overall symptom summary score and with a higher frequency of symptoms. For example, in patients with at least 15 years of ART exposure, only 27.3% of the patients did not report at least one

    Full Text Available Abstract Background Abacavir (ABC treatment has been associated with an increased incidence of myocardial infarction. The pathophysiological mechanism is unknown. In this study markers of inflammation and coagulation in HIV-infected patients using antiretroviral therapy with or without ABC were examined to pinpoint a pathogenic mechanism. Given the important role of high sensitivity C-reactive protein (hsCRP levels in predicting cardiovascular risk, patient groups were also analyzed according to hsCRP levels. Methods Patients treated with ABC and a matched control group treated without ABC were selected retrospectively. Vascular endothelial growth factor (VEGF and markers of endothelial cell activation (von Willebrand factor (vWF, factor VIII, fibrin formation (fibrinogen, D-dimer, prothrombin fragment 1+2 (F1+2, endogenous thrombin potential (ETP, anticoagulation markers (protein C and S, activated protein C sensitivity ratio (APCsr and inflammation markers (IL-6, hsCRP were measured in citrated plasma. Results A total of 81 patients were included of whom 27 patients used an ABC-containing regimen and 54 used a non-ABC-containing regimen. Patient characteristics were not significantly different between the groups except for longer duration of use of the current antiretroviral regimen in the ABC group (p = 0.01. The median time on ABC was 68 months (interquartile range 59-80 months. No differences in coagulation and inflammation markers according to ABC use were observed. For the whole patient group elevated vWF and F1+2 levels were observed in 23% and 37%, respectively. Compared to the reference ranges for the general population increased APCsr was found in 79% and lower protein C and VEGF levels in 40% and 43%, respectively. Patients in the high-risk category for cardiovascular disease with hsCRP levels > 3 mg/L had significantly higher fibrinogen, D-dimer, F1+2 and ETP levels compared to patients from the low-risk category with hsCRP levels

    The human immunodeficiency virus (HIV) and HIV-associated tuberculosis (TB-HIV) epidemics remain uncontrolled in many resource-limited regions, especially in sub-Saharan Africa. The scale of these epidemics requires the consideration of innovative bold interventions and 'out-of-the-box' thinking. To this end, a symposium entitled 'Controversies in HIV' was held at the 40th Union World Conference on Lung Health in Cancun, Mexico, in December 2009. The first topic debated, entitled 'Annual HIV testing and immediate start of antiretroviral therapy for all HIV-infected persons', received much attention at international conferences and in the literature in 2009. The second topic forms the subject of this article. The rationale for the use of empirical TB treatment is premised on the hypothesis that in settings worst affected by the TB-HIV epidemic, a subset of HIV-infected patients have such a high risk of undiagnosed TB and of associated mortality that their prognosis may be improved by immediate initiation of empirical TB treatment used in conjunction with antiretroviral therapy. In addition to morbidity and mortality reduction, additional benefits may include prevention of nosocomial TB transmission and TB preventive effect. Potential adverse consequences, however, may include failure to consider other non-TB diagnoses, drug co-toxicity, compromised treatment adherence, and logistical and resource challenges. There may also be general reluctance among national TB programmes to endorse such a strategy. Following fruitful debate, the conclusion that this strategy should be carefully evaluated in randomised controlled trials was strongly supported. This paper provides an in-depth consideration of this proposed intervention. PMID:21333094

    Background Retaining HIV patients in medical care promotes access to antiretroviral therapy, viral load suppression, and reduced HIV transmission to partners. We estimate the programmatic costs of a US multisite randomized controlled trial of an intervention to retain HIV patients in care. Methods Six academically affiliated HIV clinics randomized patients to intervention (enhanced personal contact with patients across time coupled with basic HIV education) and control [standard of care (SOC)] arms. Retention in care was defined as 4-month visit constancy, that is, at least 1 primary care visit in each 4-month interval over a 12-month period. We used microcosting methods to collect unit costs and measure the quantity of resources used to implement the intervention in each clinic. All fixed and variable labor and nonlabor costs of the intervention were included. Results Visit constancy was achieved by 45.7% (280/613) of patients in the SOC arm and by 55.8% (343/615) of patients in the intervention arm, representing an increase of 63 patients (relative improvement 22.1%; 95% confidence interval: 9% to 36%; P estimated cost per additional patient retained in care beyond SOC was $3834. Conclusions Our analyses showed that a retention in care intervention consisting of enhanced personal contact coupled with basic HIV education may be delivered at fairly low cost. These results provide useful information for guiding decisions about planning or scaling-up retention in care interventions for HIV-infected patients. PMID:25469520

    Full Text Available Tuberculosis (TB/HIV co-infection significantly changes the natural history of both diseases. Proper comprehension and clinical management of co-infected TB/HIV patients is still a challenge, particularly in places like Brazil, where both types of infection are prevalent. OBJECTIVES: Evaluate the frequency of the clinical forms of TB in HIV-infected patients; correlate the clinical forms of TB with the level of immunodeficiency; evaluate the response to therapy with different regimens for the treatment of TB; identify potential prognostic factors in TB/HIV patients. MATERIAL AND METHODS: The following data were collected at the beginning of the study: medical history, epidemiological background, physical examination, and laboratory evaluation (complete blood cell count, T lymphocyte subsets, viral load and tuberculin test. Monthly clinical follow-up was performed, with attention to adverse reactions to tuberculostatic drugs. TCD4+/CD8+ lymphocyte counts and quantification of the viral load were performed after 2, 4, 6, 10 and 15 months of follow-up. RESULTS: The study population consisted of 78 patients (45 males and 33 females and their mean age was 36.4 ± 7.9 years The mean TCD4+ count values were higher in patients with the cavitary pulmonary form and lower in patients with disseminated forms. There were no significant differences in the mean TCD8+ cells counts . in the different clinical forms of TB. However, the mean laboratory values for hemoglobin, hematocrit and leucocytes at study entry did differ significantly among the various clinical forms of TB. At the end of the trial, the Tb recovery rate was of 78%, with four cases (5% of treatment failure, eight (11% treatment discontinuations and five deaths (6.4%. The highest rate of treatment failure (75% was observed among patients with the disseminated form. Lower TCD4+ mean values were observed in cases of treatment failure and death. There was a correlation between the TCD4+ cell values

    AIM: To determine the prevalence of Helicobacter pylori (H pylori) among dyspeptic patients and to assess the relationship between H pylori infection, blood group, HIV infection and life style of the patients.METHODS: In a hospital-based cross-sectional study,patients attending Outpatient Department of University of Gondar Hospital were enrolled. Socio-demographic information was collected using questionnaires. Serum was analyzed for anti-H pylori IgG antibodies using a commercial kit. HIV serostatus was determined by enzyme-linked immunosorbent assay (ELISA). Blood grouping was performed by slide agglutination tests.RESULTS: A total of 215 dyspeptic patients were included in the study. One hundred and sixteen patients (54%) were females and 99 (46%) were males. Anti-H pylori IgG antibodies were detected in sera of 184 (85.6%) patients. The prevalence was significantly higher in patients aged 50 years and above. Twenty point five percent of the patients were found to be seropositive for HIV. No significant association was found between sex,ABO blood groups, consumption of spicy diets, socioeconomic status and seropositivity for H pylori. However,alcohol consumption was significantly associated with H pylori serology.CONCLUSION: The prevalence of H pylori infection is associated with a history of alcohol intake and older age.The effect of different diet, alcohol and socioeconomic status as risk factors for H pylori infection needs further study.

    Full Text Available We report the case of a 47-year-old female patient with rheumatoid arthritis and HIV infection presenting with a 3-week history of a painful swollen knee, increased serum inflammatory markers, and a low CD4 lymphocyte count. The diagnosis of TB arthritis was made by synovial fluid culture, GeneXpert/PCR, and confirmed by histopathology of a synovial biopsy. A mini literature review suggests that although HIV infection is associated with extrapulmonary TB, osteoarticular TB is a relatively unusual presentation in an HIV positive patient. The diagnostic utility of the GeneXpert test is explored. We also describe the patient’s good response to an intra-articular corticosteroid injection in combination with standard anti-TB therapy.

    Objective To assess the current frequency of ART-associated grade 3–4 transaminase elevations (TE) and grade 4 total bilirubin elevations (TBE) in HIV-infected patients with chronic hepatitis B and/or C, who start a new regimen of ART. Patients and Methods A total of 192 pre-treated or treatment-naive HIV infected patients with HBV and/or HCV-coinfection who started ART in eight Southern Spanish centers from July/2011-December/2013, were followed for 12 months in this prospective study. Results Forty-one (21.4%) subjects had been naïve to ART, median (IQR) follow-up was 11.6 (5.6–12.9) months. The most frequently initiated NRTI were tenofovir/emtricitabine [49 patients (25.5%)]. Eighty-nine (46.4%) patients started a ritonavir-boosted protease inhibitor and 77 (40.1%) individuals a NNRTI. Raltegravir and maraviroc were initiated in 24 (12.5%) and 9 (4.7%) individuals. Ten [5.21%; 95% confidence interval (CI): 2.53%-9.37%] patients presented grade 3 TE, while 8 (4.17%; 95%CI: 1.82%-8.04%) subjects showed grade 4 TBE. No episodes of grade 4 TE or ART discontinuation due to hepatotoxic events were observed. The use of ritonavir-boosted atazanavir was the only independent predictor for grade 4 TBE [adjusted odds ratio: 7.327 (95%CI: 1.417–37.89); p = 0.018] in an analysis adjusted for age, sex and baseline HIV-RNA levels, while no factor could be independently associated with grade 3–4 TE. Conclusions Currently, the frequency of severe ART-associated TE and TBE under real-life conditions in patients with chronic viral hepatitis is similar to what has been reported previously. However, episodes of grade 4 TE are less frequent and severe TE appears to be of lesser concern. PMID:26848975

    Full Text Available Abstract Background HBV-HIV co-infection is associated with an increased liver-related morbidity and mortality. However, little is known about the natural history of chronic hepatitis B in HIV-infected individuals under highly active antiretroviral therapy (HAART receiving at least one of the two drugs that also affect HBV (TDF and LAM. Information about HBeAg status and HBV viremia in HIV/HBV co-infected patients is scarce. The objective of this study was to search for clinical and virological variables associated with HBeAg status and HBV viremia in patients of an HIV/HBV co-infected cohort. Methods A retrospective cross-sectional study was performed, of HBsAg-positive HIV-infected patients in treatment between 1994 and 2007 in two AIDS outpatient clinics located in the São Paulo metropolitan area, Brazil. The baseline data were age, sex, CD4 T+ cell count, ALT level, HIV and HBV viral load, HBV genotype, and duration of antiretroviral use. The variables associated to HBeAg status and HBV viremia were assessed using logistic regression. Results A total of 86 HBsAg patients were included in the study. Of these, 48 (56% were using combination therapy that included lamivudine (LAM and tenofovir (TDF, 31 (36% were using LAM monotherapy, and 7 patients had no previous use of either one. Duration of use of TDF and LAM varied from 4 to 21 and 7 to 144 months, respectively. A total of 42 (48. 9% patients were HBeAg positive and 44 (51. 1% were HBeAg negative. The multivariate analysis revealed that the use of TDF for longer than 12 months was associated with undetectable HBV DNA viral load (serum HBV DNA level p = 0. 047. HBeAg positivity was associated with HBV DNA > 60 UI/ml (p = 0. 001 and ALT levels above normality (p = 0. 038. Conclusion Prolonged use of TDF containing HAART is associated with undetectable HBV DNA viral load. HBeAg positivity is associated with HBV viremia and increased ALT levels.

    Full Text Available Introduction Hepatitis B virus (HBV and human immunodeficiency virus (HIV infections are two of the world's most important infectious diseases. Our objective was to determine the hepatitis B surface antigen (HBsAg and hepatitis B core antibody (anti-HBc prevalences among adult HIV-infected patients and identify the associations between socio-demographic variables and these HBV infection markers. Methods This study was performed from October 2012 to March 2013. Three hundred HIV-seropositive patients were monitored by the Clinical Analysis Laboratory of Professor Polydoro Ernani de São Thiago University Hospital, Santa Catarina, Brazil. The blood tests included HBsAg, anti-HBc immunoglobulin M (IgM and total anti-HBc. Patients reported their HIV viral loads and CD4+ T-cell counts using a questionnaire designed to collect sociodemographic data. Results The mean patient age was 44.6 years, the mean CD4 T-cell count was 525/mm3, the mean time since beginning antiretroviral therapy was 7.6 years, and the mean time since HIV diagnosis was 9.6 years. The overall prevalences of HBsAg and total anti-HBc were 2.3% and 29.3%, respectively. Among the individuals analyzed, 0.3% were positive for HBsAg, 27.3% were positive for total anti-HBc, and 2.0% were positive either for HBsAg or total anti-HBc and were classified as chronically HBV-infected. Furthermore, 70.3% of the patients were classified as never having been infected. Male gender, age >40 years and Caucasian ethnicity were associated with an anti-HBc positive test. Conclusions The results showed an intermediate prevalence of HBsAg among the studied patients. Moreover, the associations between the anti-HBc marker and socio-demographic factors suggest a need for HBV immunization among these HIV-positive individuals, who are likely to have HIV/HBV coinfection.

    Full Text Available Background and Objectives   HIV epidemics may differ among epidemiological contexts. We aimed at constructing an HIV clinical cohort whose main epidemiological, clinical and therapeutical characteristics are described (the CalabrHIV cohort, Calabria Region, Southern Italy.   Methods   The CalabrHIV cohort includes all HIV patients on active follow-up in all infectious disease centers in the Calabria Region as at October 2014. All information were recorded in a common electronic database. Not-infectious co-morbidities (such as cardiovascular diseases, bone fractures, diabetes, renal failure and hypertension were also studied.   Results   548 patients (68% males; 63% aged 50 years-old patients than in <50 years-old ones (30% vs. 6%; p<0.0001. Co-morbidity was more frequent in HCV and/or HBV co-infected than in HIV mono-infected patients (46.6% vs. 31.7%: p=0.0006.   Conclusion   This cohort presentation study sheds light, for the first time, on HIV patients’ characteristics in the Calabria Region. Despite a small number of officially reported cases, the size of the cohort was substantial. We showed that HIV infected patients with chronic hepatites, were affected by concomitant not-infectious co-morbidities more than the HIV mono-infected individuals. New HCV treatments are eagerly awaited.

    Full Text Available Background: The significant decrease in mortality has resulted in a large number of individuals aged over 50 living with HIV infection. Additionally, the coexistence of certain pathologies suggests premature aging. In this scenario, the presence of aging-associated symptoms in the physician-patient dialogue is yet to be explored. Methods: Cross-sectional observational study to evaluate the presence of aging-associated symptoms in the physician-patient dialogue and to explore the possible differences between genders in a sample of 100 HIV-1 infected subjects diagnosed at least 15 years ago. The survey assessed questions/comments made by the patient, questions/comments made by the physician and patients’ interest in obtaining more information than was provided. Number of patients and percentages were given and compared using the w2 or Fisher exact test (as appropriate. Results: Participants were 60 men and 40 women, diagnosed with HIV infection a median (IQ of 18 (15.7–21 years ago, who had a nadir CD4 and CD4 cell count at the study entry of 172 (95–272 and 543 (403–677, respectively. Eighty percent of the subjects had VL <25 copies and 42% were HCV/HIV co-infected (31 subjects with low fibrosis stage. The infection route had been mainly intravenous drug use (37% and MSM (32%. Men and women had similar demographic and clinical characteristics. Sixty-two percent of the participants acknowledged asking their physicians about aging-associated symptoms (58% men vs 66% women; p=0.50, 48% reported that their physicians had provided information without having been asked (48% men vs 55% women; p=0.51 and 75% confirmed that they would like to have more information about aging-associated symptoms (22% men vs 80% women; p<0.001. Conclusions: Around half of the men and women interviewed had discussed aging-associated symptoms with their physician. However, this seemed insufficient for four-fifths of the women, who would have liked to have obtained

    Full Text Available BACKGROUND: Since establishment of Zimbabwe's National Antiretroviral Therapy (ART Programme in 2004, ART provision has expanded from <5,000 to 369,431 adults by 2011. However, patient outcomes are unexplored. OBJECTIVE: To determine improvement in health status, retention and factors associated with attrition among HIV-infected patients on ART. METHODS: A retrospective review of abstracted patient records of adults ≥ 15 years who initiated ART from 2007 to 2009 was done. Frequencies and medians were calculated for rates of retention in care and changes in key health status outcomes at 6, 12, 24 and 36 months respectively. Cox proportional hazards models were used to determine factors associated with attrition. RESULTS: Of the 3,919 patients, 64% were female, 86% were either WHO clinical stage III or IV. Rates of patient retention at 6, 12, 24 and 36 months were 90.7%, 78.1%, 68.8% and 64.4%, respectively. After ART initiation, median weight gains at 6, 12, and 24 months were 3, 4.5, and 5.0 kgs whilst median CD4+ cell count gains at 6, 12 and 24 months were 122, 157 and 279 cells/µL respectively. Factors associated with an increased risk of attrition included male gender (AHR 1.2; 95% CI, 1.1-1.4, baseline WHO stage IV (AHR 1.7; 95% CI, 1.1-2.6, lower baseline body weight (AHR 2.0; 95% CI, 1.4-2. 8 and accessing care from higher level healthcare facilities (AHR 3.5; 95% 1.1-11.2. CONCLUSIONS: Our findings with regard to retention as well as clinical and immunological improvements following uptake of ART, are similar to what has been found in other settings. Factors influencing attrition also mirror those found in other parts of sub-Saharan Africa. These findings suggest the need to strengthen earlier diagnosis and treatment to further improve treatment outcomes. Whilst decentralisation improves ART coverage it should be coupled with strategies aimed at improving patient retention.

    The introduction of Highly Active Antiretroviral Therapy (HAART) into clinical practice has dramatically changed the natural approach of HIV-related cancers. Several studies have shown that intensive antiblastic chemotherapy (AC) is feasible in HIV-infected patients with cancer, and that the outcome is similar to that of HIV-negative patients receiving the same AC regimens. However, the concomitant use of HAART and AC can result in drug accumulation or possible toxicity with consequent decreased efficacy of one or both classes of drugs. In fact, many AC agents are preferentially metabolized by CYP450 and drug-drug interactions (DDIs) with HAART are common. Therefore, it is important that HIV patients with cancer in HAART receiving AC treatment at the same time receive an individualized cancer management plan based on their liver and renal functions, their level of bone marrow suppression, their mitochondrial dysfunction, and their genotype profile. The rationale of this review is to summarize the existing data on the impact of HAART on the clinical management of cancer patients with HIV/AIDS and DDIs between antiretrovirals and AC. In addition, in order to maximize the efficacy of antiblastic therapy and minimize the risk of drug-drug interaction, a useful list of pharmacogenomic markers is provided. PMID:27065862

    This qualitative study examined the role of experienced HIV-infected lay individuals who work in HIV medical care settings as educators. Participants in this study had been in the role an average of 4 years, and referred to their work as "peering," a newly coined verb in the vein of nursing. An overarching theme was that the title "peer educator" captured neither the scope of their work, nor the skill set they contribute to patient care. Peers brought unique contributions to the HIV care team that were vital to encouraging patients to stay engaged in care. Peers felt undervalued and expressed the wish to be "professionalized." Results from this study suggest that peers show promise as behavior change agents who can model healthful behaviors, particularly for newly diagnosed patients or those struggling with engagement in HIV care and adherence to treatment. However, peers need and want more formal training in behavior change science, and peer-led services must become more uniform and readily available to patients across HIV care settings. Research is needed to document the positive impact that peers can have on HIV-related health outcomes and to increased knowledge about the attributes of successful peers. PMID:23883321

    We carried out a retrospective, multicenter study of a cohort of 298 asymptomatic HIV-infected patients who switched from a regimen based on 2 nucleoside reverse transcriptase inhibitors + protease inhibitor (PI)/nonnucleoside reverse transcriptase inhibitor or ritonavir-boosted PI monotherapy to emtricitabine/rilpivirine/tenofovir disoproxil fumarate (FTC/RPV/TDF) to analyze lipid changes. At 24 weeks, 284 (95.3%) patients were still taking the same regimen, maintaining similar CD4 counts as at baseline (651 versus 672 cells/mm(3), P = .08), and 98.9% of them with an undetectable viral load. Eight of the other 14 patients were lost to follow up and 6 (2.0%) ceased the new regimen: 3 due to adverse effects, 2 due to virologic failure, and 1 due to abandonment. The mean levels of fasting total cholesterol (TC), low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), and triglycerides fell at 12 and 24 weeks, with no changes detected in the TC to HDL-C ratio.

    Full Text Available Background: Human Parvovirus B19 (PVB19 is among the aetiology of aplastic crisis in human immunodeficiency virus (HIV-infected patients. Several studies have indicated the importance of an infection agent in bringing about complications in immuno-compromised patients. The current study aims to determine the seroprevalence of IgM and IgG antibodies to PVB19 among HIV-positive patients and its association with clinical and epidemiological factors. Materials and Methods: In a case control study, 90 HIV-positive patients were compared with 90 sex and age matched healthy controls in terms of anti-PVB19 IgG and IgM along with other primary clinical and laboratory features. Results: The overall prevalence of positive anti-PVB19 IgG among HIV patients and controls were 81.1% and 28.9%, respectively (P < 0.001. None of the subjects showed positive results for anti-PVB19 IgM. Patients with CD4 + cell count <200 showed higher seroprevalence of positive anti-PVB19 IgG which did not reach statistically significant. However, anti-PVB19 IgG seropositivity differed significantly between HIV patients on different regimens of antiretroviral therapy (ART (P < 0.05. Conclusion: Immunity against PVB19 is more prevalent among HIV-positive patients compared to healthy controls. However, positive HIV status is not associated with acute PVB19 infection. The presence of anti-PVB19 IgG does not necessarily protect the body from further complications like anaemia. Given the results of the study, AIDS patients are recommended to undergo screening for parvovirus antibody in order to prevent complications like aplastic anaemia.

    Full Text Available Abstract Background in HIV-infected patients with HCV-related chronic hepatitis, liver impairment and drug toxicity may substantially reduce the number of possible therapeutic options. Case Description we here describe the case of an HCV-HIV coinfected woman who had repeated severe episodes of drug-related liver toxicity with indinavir, saquinavir, fosamprenavir, and darunavir, with minimal further therapeutic options left in this class. Previous treatment-limiting side effects with efavirenz and nevirapine also precluded use of non-nucleoside reverse transcriptase inhibitors. Introduction of an integrase-inhibitor regimen based on raltegravir, tenofovir, and emtricitabine allowed a prompt achievement of undetectable viral load and a substantial rise of CD4 count to high levels, with no subsequent episodes of hepatic toxicity, and no other side effects. Conclusions given the relatively common prevalence of HCV-related chronic hepatitis among people with HIV, raltegravir might represent an important alternative option for a substantial number of patients who cannot be treated with protease inhibitors or NNRTI because of drug-related hepatic toxicity.

    Cristina Gervasoni

    Full Text Available Ritonavir-boosted atazanavir (ATV/r is a relatively well tolerated antiretroviral drug. However, side effects including hyperbilirubinemia, dyslipidemia, nephrolithiasis and cholelithiasis have been reported in the medium and long term. Unboosted ATV may be selected for some patients because it has fewer gastrointestinal adverse effects, less hyperbilirubinemia and less impact on lipid profiles.We investigated the distribution of ATV plasma trough concentrations according to drug dosage and the potential relationship between ATV plasma trough concentrations and drug-related adverse events in a consecutive series of 240 HIV-infected patients treated with ATV/r 300/100 mg (68% or ATV 400 mg (32%.43.9% of patients treated with ATV/r 300/100 mg had ATV concentrations exceeding the upper therapeutic threshold. A significant and direct association has been observed between the severity of hyperbilirubinemia and ATV plasma trough concentrations (ATV concentrations: 271 [77-555], 548 [206-902], 793 [440-1164], 768 [494-1527] and 1491 [1122-1798] ng/mL in patients with grade 0, 1, 2, 3 and 4 hyperbilirubinemia, respectively. In an exploratory analysis we found that patients with dyslipidemia or nephrolitiasis had ATV concentrations significantly higher (582 [266-1148], and 1098 [631-1238] ng/mL, respectively (p<0.001, as compared with patients with no ATV-related complications (218 [77-541] ng/mL.A significant proportion of patients treated with the conventional dosage of ATV (300/100 had plasma concentrations exceeding the upper therapeutic threshold. These patients that are at high risk to experience ATV-related complications may benefit from TDM-driven adjustments in ATV dosage with potential advantages in terms of costs and toxicity.

    Background The initiation and expansion of China's national free antiretroviral therapy program has led to significant improvement of survival among its participants. Success of further scaling up treatment coverage rests upon intensifying HIV screening and efficient linkage of care. Timely CD4 cell count testing after HIV diagnosis is necessary to determine whether a patient meets criteria for antiretroviral treatment, and represents a crucial link to engage HIV-infected patients in appropriate care, which has not been evaluated in China.Methods We evaluated all patients ≥16 years who tested HIV positive from 2005 to 2009 in Yunnan and Guangxi.Multivariate Logistic regression models were applied to identify factors associated with lack of CD4 cell count testing within 6 months after HIV diagnosis.Results A total of 83 556 patients were included. Over the study period, 30 635 (37%) of subjects received a CD4 cell count within 6 months of receiving the HIV diagnosis. The rate of CD4 cell count testing within 6 months of HIV diagnosis increased significantly from 7% in 2005 to 62% in 2009. Besides the earlier years of HIV diagnosis, negative predictors for CD4 cell count testing in multivariate analyses included older age, not married or unclear marriage status,incarceration, diagnosis at sexual transmitted disease clinics, mode of HIV transmission classified as men who have sex with men, intravenous drug users or transmission route unclear, while minority ethnicity, receipt of high school or higher education, diagnosis at voluntary counseling and testing clinics, and having HIV positive parents were protective.Conclusions Significant progress has been made in increasing CD4 testing among newly diagnosed HIV positive patients in Yunnan and Guangxi from 2005-2009. However, a sizable proportion of HIV positive patients still lack CD4testing within 6 months of diagnosis. Improving CD4 testing, particularly among patients with identified risk factors, is essential to

    Marshall J Glesby

    Full Text Available BACKGROUND: Recombinant human growth hormone (rhGH reduces visceral adipose tissue (VAT volume in HIV-infected patients but can worsen glucose homeostasis and lipoatrophy. We aimed to determine if adding rosiglitazone to rhGH would abrogate the adverse effects of rhGH on insulin sensitivity (SI and subcutaneous adipose tissue (SAT volume. METHODOLOGY/PRINCIPAL FINDINGS: Randomized, double-blind, placebo-controlled, multicenter trial using a 2×2 factorial design in which HIV-infected subjects with abdominal obesity and insulin resistance were randomized to rhGH 3 mg daily, rosiglitazone 4 mg twice daily, combination rhGH + rosiglitazone, or double placebo (control for 12 weeks. The primary endpoint was change in SI by frequently sampled intravenous glucose tolerance test from entry to week 12. Body composition was assessed by whole body magnetic resonance imaging (MRI and dual Xray absorptiometry (DEXA. Seventy-seven subjects were randomized of whom 72 initiated study drugs. Change in SI from entry to week 12 differed across the 4 arms by 1-way ANCOVA (P = 0.02; by pair-wise comparisons, only rhGH (decreasing SI; P = 0.03 differed significantly from control. Changes from entry to week 12 in fasting glucose and glucose area under the curve on 2-hour oral glucose tolerance test differed across arms (1-way ANCOVA P = 0.004, increasing in the rhGH arm relative to control. VAT decreased significantly in the rhGH arms (-17.5% in rhGH/rosiglitazone and -22.7% in rhGH but not in the rosiglitazone alone (-2.5% or control arms (-1.9%. SAT did not change significantly in any arm. DEXA results were consistent with the MRI data. There was no significant rhGH x rosiglitazone interaction for any body composition parameter. CONCLUSIONS/SIGNIFICANCE: The addition of rosiglitazone abrogated the adverse effects of rhGH on insulin sensitivity and glucose tolerance while not significantly modifying the lowering effect of rhGH on VAT.
