25-hydroxy vitamin D levels in healthy premenopausal women: Association with bone turnover markers and bone mineral density

2008

Abstract Background Vitamin D deficiency is very common in elderly people while there are very few reports on its incidence, determinants and metabolic consequences in young subjects. Results In 608 young healthy premenopausal women participating in the BONTURNO study, levels of 25-hydroxyvitamin D [25(OH)D] below 20 ng/ml were found in almost a third of the women. Its levels were inversely ( P 2 ) and directly with sunlight exposure during the summer time, and latitude: i.e. the higher the latitude over Italy, the higher the 25(OH)D level. In women on contraceptive pill the mean 25(OH)D level was significantly increased even when the data were adjusted for age, BMI and sun exposure. 25(OH)…

Thiamine for the treatment of nucleoside analogue-induced severe lactic acidosis

1999

Nucleoside analogue-induced lactic acidosis is an often fatal condition in patients with HIV. There is only one report of successful treatment with riboflavin. We describe a 30-year-old female with AIDS and nucleoside analogue-induced lactic acidosis that exacerbated shortly after introducing total parenteral nutrition and reversed within hours after the addition of thiamine. Successful treatment of nucleoside analogue-induced lactic acidosis with a high dose of thiamine supports the hypothesis that vitamin deficiency is an important cofactor in the development of this rare and unpredictable condition in patients with HIV. We suggest that high dose B-vitamins should be given to any patient …

2015

SummaryObjective To assess the effect of 4 years’ growth hormone (GH) replacement on glucose homeostasis and evaluate factors affecting glycosylated haemoglobin (HbA1c) in adults with growth hormone deficiency (GHD). Design NordiNet® International Outcome Study, a noninterventional study, monitors long-term effectiveness and safety of GH replacement [Norditropin® (somatropin), Novo Nordisk A/S] in real-life clinical practice. Patients Nondiabetic patients (n = 245) with adult-onset GHD (age ≥20 years at GH start), ≥4 years’ GH replacement and HbA1c values at baseline and 4 years were included in the analysis. Measurements Changes from baseline (∆) to 4 years in HbA1c, fasting plasma glucose…

Treatment of Patients with Chronic Type B Hepatitis and Concurrent Human Immunodeficiency Virus Infection with a Combination of Interferon Alpha and …

1989

Six patients with chronic type B hepatitis and concurrent infection with the immunodeficiency virus were treated with 600 mg azidothymidine (AZT)/day and 3 X 10(6) units of interferon-alpha (IFN-alpha) every other day for a total of 4 months. None of the patients treated lost the hepatitis B virus (HBV). HBV-DNA concentrations were not significantly influenced by this treatment. Human immunodeficiency virus (HIV) infection was also not affected except for a transient rise in CD 4-positive cells in 2 individuals, who had initially low CD 4-positive cells. Treatment did not influence the presence of HIV-Ag in the serum. In conclusion, a combination therapy of IFN and AZT does not seem to be b…

MMP-7 promoter polymorphisms do not influence CD4+ recovery and changes in plasma viral load during antiretroviral therapy for HIV-1 infection.

2005

Summary Matrix metalloproteinase-7 (MMP-7) generates soluble Fas Ligand (FasL), which is involved in the apoptotic loss of CD4+ T cells during HIV infection. We evaluated whether two polymorphisms in MMP-7 promoter could influence CD4+ recover in response to antiretroviral therapy, and found that these polymorphisms are ineffective.

Influence of lifelong cumulative HIV viremia on long-term recovery of CD4+ cell count and CD4+/CD8+ ratio among patients on combination antiretrovira…

2015

OBJECTIVE We explored the impact of lifelong cumulative HIV viremia on immunological recovery during antiretroviral therapy, according to the timing of treatment initiation. METHODS We estimated lifelong cumulative HIV viremia in patients followed in the ANRS PRIMO cohort since primary infection, including 244 patients who started treatment during PHI and had at least one treatment interruption, and 218 patients who started treatment later but with no interruptions. The impact of cumulative viremia on current immunological status was analysed using linear and logistic regression models. RESULTS At the last visit on treatment, median CD4 cell count was 645 cells/μl in the early/intermittent …

Immunogenicity and safety of an inactivated hepatitis A vaccine in anti-HIV positive and negative homosexual men.

1995

The immunogenicity, reactogenicity, and safety of an inactivated hepatitis A vaccine were assessed in anti-HIV positive homosexual men. Fourteen anti-HIV positive (group 1) and 20 anti-HIV negative (group 2) men received vaccine (containing 720 ELISA units of hepatitis A antigen per dose) intramuscularly at 0, 1, and 6 months. Twelve unvaccinated anti-HIV positive men (group 3) were included as controls to evaluate disease progression. Seroconversion (anti-hepatitis V virus (HAV ⩾20 mlU/ml) was higher in group 2 than group 1 at months 2 (100% vs. 73%) and 7 (l00%vs. 77%). Group 2 had higher antibody titres than group 1 at months 1 (201 vs. 92 mlU/ml) and 7 (1, 687 vs. 636 mlU/ml). The decli…

Long-term CD4+ T-cell count evolution after switching from regimens including HIV nucleoside reverse transcriptase inhibitors (NRTI) plus protease in…

2011

Abstract Background Data regarding CD4+ recovery after switching from protease inhibitor (PI)-based regimens to regimens not containing PI are scarce. Methods Subjects with virological success on first-PI-regimens who switched to NNRTI therapy (NNRTI group) or to nucleoside reverse transcriptase (NRTI)-only (NRTI group) were studied. The effect of the switch on the ongoing CD4+ trend was assessed by two-phase linear regression (TPLR), allowing us to evaluate whether a change in the CD4+ trend (hinge) occurred and the time of its occurrence. Furthermore, we described the evolution of the frequencies in CD4-count classes across four relevant time-points (baseline, before and immediately after…

Capacity assessment for provision of quality sexual reproductive health and HIV-integrated services in Karamoja, Uganda

2020

Introduction: Sexual and reproductive health (SRH) and Human Immunodeficiency Virus (HIV) are crucial global health issues. Uganda continues to sustain a huge burden of HIV and AIDS.
 Methods: A cross-sectional health facility-based assessment was performed in November and December 2016 in Karamoja Region, northern Uganda. All the 126 health facilities (HFs) in Karamoja, including 5 hospitals and 121 Health Centers (HCs), covering 51 sub-counties of the 7 districts were assessed. We assessed the capacity of a) leadership and governance, b) human resource, c) service delivery, d) SRH and HIV service integration and e) users satisfaction and perceptions.
 Results: 64% of the establi…

Lymphocyte subpopulations in solvent-exposed workers.

1986

To estimate the cellular immune response of workers highly exposed to mixtures of organic solvents, subpopulations of peripheral blood lymphocytes (PBLs) were analyzed. For this, the PBLs of nine floorers (aged 25–58 years, exposure time 8–35 years) were subsequently labelled with monoclonal antibodies OKT 4, OKT 8, OKT 11, anti-Leu 7 and anti-Leu 12. Analysis was made by a FACS IV cell sorter (Becton-Dickinson, USA). The control group consisted of matched pairs of healthy donors. In the exposed group we found a decrease in the OKT 11 (all) T cell fraction, a decrease in the OKT 4 helper cells, an increase in the anti-Leu 7 positive cells, mostly natural killer cells, an important increase …
