RESUMO

CONTEXT: Several alterations in thyroid function test (TFT) results have been associated with mortality in elderly patients. OBJECTIVE: Our aim was to investigate the relationship between TFT results and all-cause and cardiovascular (CV) mortality in aged hospitalized patients. DESIGN: A 7-year prospective observational study was conducted. TFTs were performed at hospital admission, and mortality was registered in the follow-up period. PATIENTS: Participants were 404 patients aged >65 years admitted to the Department of Geriatrics, Hospital General, Segovia, Spain, for any reason during 2005. MAIN OUTCOME MEASURES: The study evaluated the association between TFT results and mortality from all causes and CV diseases. METHODS: TSH, free T4, and free T3 (FT3) were measured on the first day of admission. In-hospital and total survival times, number of deaths, and all-cause and CV mortality were registered until the census date on January 1, 2012. RESULTS: During the study, 323 patients (80%) died. Kaplan-Meier analysis showed that median survival time for all-cause mortality was significantly lower in patients in the first tertile of serum FT3, in the first tertile of TSH, and in the first tertile of serum free T4 concentrations. Multivariate adjusted Cox regression analysis showed that the history of cancer (hazard ratio, 1.60; 95% confidence interval, 1.12-2.28; P = .009), age (1.03; 1.01-1.06; P = .003), and FT3 levels (0.72; 0.63-0.84; P < .001) were significant factors related to all-cause mortality. The cause of death was known in 202 patients. Of this group, 61 patients (30.2%) died of CV disease. Patients in the first tertile of TSH and FT3 exhibited a significant higher mortality due to CV disease. In the adjusted Cox regression analysis, FT3 was a significant predictor of CV mortality (0.76; 0.63-0.91; P = .004). CONCLUSIONS: Alterations in TFT results during hospitalization are associated with long-term mortality in elderly patients. In particular, low FT3 levels are significantly related to all-cause and CV mortality.

RESUMO

We report for the first time a case of nephrotic-range proteinuria adequately controlled by using dopamine agonists. A 40-year-old man was studied because of persistent asymptomatic nephrotic proteinuria despite lifestyle modifications and treatment with converting enzyme inhibitors. The renal biopsy specimen did not show histopathologic changes. In the follow-up period, a giant prolactinoma was found by chance with extremely high prolactin (PRL) values. After establishing cabergoline therapy, we achieved a remarkable decrease in both serum PRL levels and tumor mass, and surprisingly, proteinuria disappeared. We discuss the possible pathogenic mechanisms of proteinuria that may correspond to PRL level in urine (prolactinuria) or another tumor-related protein.

RESUMO

OBJECTIVE: We report the acute effects of cinacalcet on calcium and parathyroid hormone (PTH) levels and the effects of 1 year of therapy on calcium and phosphorus metabolism in 4 patients with persistent primary hyperparathyroidism (PHPT) after unsuccessful parathyroidectomy. PATIENTS: Four patients (3 women; age, 24 to 71 years) were studied after 1 to 3 parathyroid operative procedures. All of them had elevated serum total and ionized calcium levels, decreased serum phosphorus, and increased concentrations of intact PTH. METHODS: Calcium and PTH responses to an acute dose of oral cinacalcet (30 mg) were studied at baseline. Effects of cinacalcet (30 mg b.i.d.) on serum calcium, phosphorus, and PTH, and urinary calcium and phosphorus were studied at 1, 3, 6, and 12 months of therapy. RESULTS: PTH concentrations were reduced by 13.0% to 86.7% after acute cinacalcet administration. Chronic therapy with cinacalcet was followed by a decrement in serum total calcium (10.2% at 12 months) and ionized calcium (10.1%) and an increase in serum phosphorus (20.8%), with only a modest decrement in PTH levels (5.1%). All patients had normal serum total and ionized calcium levels at 3 to 12 months of therapy. Urinary calcium decreased by 20.0% at 12 months. CONCLUSIONS: Cinacalcet was effective in normalizing calcium and phosphorus concentrations in patients with persistent PHPT after unsuccessful parathyroidectomy.

RESUMO

Sexually transmitted disease (STD) remains a major public health challenge in developed countries, exacerbated by the advent of the HIV epidemic. The objectives of this study were to assess the prevalence of serological markers of syphilis, HIV-1/2, HTLV-I/II, HBV, and HCV infections among immigrant sex workers in Madrid, Spain and to characterize the HIV-1 variants in seropositive individuals. Sera from 762 immigrant commercial sex workers (75.3% from sub-Saharan Africa, 18.2% from South America, and 6.4% from Eastern Europe) were collected between 1998 and 2003 in Madrid and examined. Antibody detection was performed by screening assays (RPR, ELISAs) and confirmed by FTA-Abs, LIAs and Western-blot tests. HIV-1 subtyping was carried out by phylogenetic analyses of the protease and envelope genes. Antibodies to HIV-1 were found in 5.2%, while 3.5% tested positive for HBsAg, 3% for syphilis antibodies, 0.8% for HCV antibodies, and 0.2% for HTLV-I antibodies. None were reactive for HIV-2 or HTLV-II antibodies. HIV-1 seroprevalence among Africans and Ecuadorians was 4.5 and 10.9%, respectively. All HIV-1 seropositive Ecuadorians were transsexual men, and 28.6% had active syphilis infection. Up to 80% of HIV-1 positive specimens were characterized as non-B subtypes, with subtypes G, A, and G/A recombinants being the most frequent among African individuals. In contrast, South Americans with HIV-1 infection carried exclusively subtype B variants. A relatively high proportion of immigrant sex workers in Madrid were infected with HIV-1 and syphilis, whereas infections with hepatitis viruses or HTLV were uncommon.
