RESUMO

BACKGROUND: The prevalence of HIV-1 drug resistance among treatment-naïve patients ranges between 8.3% and 15% in Europe and North America. Previous studies showed that subtypes A and B were the most prevalent in the Greek HIV-1 epidemic. Our aim was to estimate the prevalence of resistance among drug naïve patients in Greece and to investigate the levels of transmission networking among those carrying resistant strains. METHODS: HIV-1 sequences were determined from 3428 drug naïve HIV-1 patients, in Greece sampled during 01/01/2003-30/6/2015. Transmission clusters were estimated by means of phylogenetic analysis including as references sequences from patients failing antiretroviral treatment in Greece and sequences sampled globally. RESULTS: The proportion of sequences with SDRMs was 5.98% (n=205). The most prevalent SDRMs were found for NNRTIs (3.76%), followed by N(t)RTIs (2.28%) and PIs (1.02%). The resistance prevalence was 22.2% based on all mutations associated with resistance estimated using the HIVdb resistance interpretation algorithm. Resistance to NNRTIs was the most common (16.9%) followed by PIs (4.9%) and N(t)RTIs (2.8%). The most frequently observed NNRTI resistant mutations were E138A (7.7%), E138Q (4.0%), K103N (2.3%) and V179D (1.3%). The majority of subtype A sequences (89.7%; 245 out of 273) with the dominant NNRTI resistance mutations (E138A, K103N, E138Q, V179D) were found to belong to monophyletic clusters suggesting regional dispersal. For subtype B, 68.1% (139 out of 204) of resistant strains (E138A, K103N, E138Q V179D) belonged to clusters. For N(t)RTI-resistance, evidence for regional dispersal was found for 27.3% and 21.6% of subtype A and B sequences, respectively. CONCLUSIONS: The TDR rate based on the prevalence of SDRM is lower than the average rate in Europe. However, the prevalence of NNRTI resistance estimated using the HIVdb approach, is high in Greece and it is mostly due to onward transmissions among drug-naïve patients.

RESUMO

BACKGROUND: Previous studies have examined the role of inflammatory markers in patients with coronary heart disease, stroke, chronic renal failure and other selected patient populations. The aim of this study was to assess the clinical utility of serum C-reactive protein (CRP) at admission in predicting outcome in hospitalized medical patients. METHODS: All patients admitted to our medical department were eligible to be included in the study. At the time of admission, demographic and clinical information was obtained. CPR was measured within 12 h of hospitalization. The results were analyzed using Cox proportional hazards multiple regression model. RESULTS: Three hundred eighty-two patients were included in the study (186 males and 196 females). Age (mean+/-standard deviation) was 70.8+/-15.7 years. Serum CRP [median (interquartile range) at admission was 29.7 mg/l (6.6-114.3). Serum CRP at admission was independently associated with in-hospital death. Levels above 120 mg/l increased the probability of fatal outcome three fold (hazard ratio=2.98, 95% confidence interval: 1.35-6.58). In patients older than 80 years, CRP at admission was a stronger predictor of in-hospital death (hazard ratio=5.41, 95% confidence interval: 1.38-21.26). CONCLUSIONS: Serum CRP at admission is an independent predictor of mortality in hospitalized patients, particularly in the elderly. Admission CRP higher than 120 mg/l was associated with increased probability of in-hospital death (three fold in the overall population and five fold in the elderly subgroup) compared with lower levels.

RESUMO

Two groups, one of 824 adult diabetics and one of 320 age and sex matched non-diabetics, were examined for abnormal glucose metabolism and calcifications on anteroposterior shoulder x rays. Two hundred and sixty two (31.8%) of the diabetics had shoulder calcification compared with 33 (10.3%) of the control group, with a preponderant localisation in the right shoulder. Diabetes of long duration treated with insulin for a long time was associated with a larger percentage of shoulder calcifications. These data and previous laboratory findings suggest a possible pathogenetic correlation between the prevalence of calcific shoulder tendinitis and diabetes.
