Abstract
Cardiovascular disease (CVD) is a main cause of death in patients with systemic lupus erythematous (SLE). Algorithms for cardiovascular risk stratification in general population underestimate the risk for CVD in SLE. Our study aimed to determine whether serum high-sensitivity cardiac troponin I (hs-cTnI) might help to identify SLE patients with subclinical atherosclerosis. Arterial stiffness was assessed measuring the carotid-femoral pulse wave velocity (PWV) in 68 SLE women with a normal or almost normal kidney function and in 71 controls of similar characteristics. None of the participants had a history of an overt CVD. Serum hs-cTnI level was measured using the chemiluminescence method. Factors associated with an increased PWV (iPWV) were identified and multivariate analysis was performed. When detectable, patients tended to have had higher hs-cTnI levels than controls [2.9 (2.3-4.0) vs 2.4 (2.2-4.1); p = 0.098] and were more likely to have detectable hs-cTnI [50% vs 28%, odds ratio (OR) 7.0; 95% confidence interval (CI) 0.008-0.013]. Also, patients with iPWV were more likely to have detectable hs-cTnI than those with normal PWV (OR 6.4; 95% CI 0.019-0.026). In the multivariate analysis, the age at SLE diagnosis (OR 1.24; 95% CI 1.04-1.48), systolic blood pressure (OR 1.28; 95% CI 1.10-1.48) and detectable hs-cTnI level (OR 2.04; 95% CI 1.18-3.50) were independently associated with an iPWV. The negative predictive value of having an iPWV with undetectable hs-cTnI levels was 88%. Hs-cTnI may be a useful biomarker for the identification of SLE patients with iPWV as a surrogated marker of subclinical atherosclerosis. Specifically targeted prospective studies are needed to confirm this hypothesis.

Abstract
OBJECTIVES The purpose of this study was to evaluate homocysteine (Hcy) serum levels in women with systemic sclerosis (SSc) compared with healthy controls and to examine possible associations between Hcy and markers of arterial stiffness. METHODS A cross-sectional study was performed at a single hospital between November 2017 and May 2019: 62 women with SSc and 62 age- and sex-matched healthy controls were enrolled. Pulse wave velocity (PWV) was measured non-invasively along the carotid-femoral arterial segment. Serum Hcy was analysed using immunonephelo-metric method. RESULTS There was a significant difference in Hcy serum levels between SSc female patients and healthy controls (11.9±3.3 vs. 10.3±2.3 μmol/ml, p=0.002). Serum levels of Hcy were positively correlated with PWV (r=0.28, p<0.05), brain natriuretic peptide (BNP) (r=0.36, p<0.05) and disease duration (r=0.38, p<0.05), within the SSc group. In addition, in the linear regression model, higher Hcy concentrations were associated with higher PWV [β=0.74 95% CI (0.085, 1.394); p=0.027], BNP [β=0.04 95% CI (0.014, 0.072); p=0.004] and disease duration [β=0.18 95% CI (0.070, 0.300); p=0.002]. In multiple linear regression model adjusting for covariants, Hcy remained positively related to the PWV [β=0.033 95% CI (0.003, 0.062); p=0.031]. CONCLUSIONS Our findings revealed a positive correlation between Hcy serum levels and PWV, which indicates that high levels of Hcy may predispose to the development of vascular stiffness in patients with SSc.

Abstract
Objective The objective of this study was to determine the safety of tattoos in patients with systemic lupus erythematosus (SLE). Methods Patients ( N = 147; ≤55 years; 92% women) were asked if they had tattoos. The characteristics of the tattoos and the immediate complications were investigated and compared with those of a matched control group. We examined retrospectively after the tattoo was completed whether there had been flare-ups or increased organ damage (Systemic Lupus International Collaborating Clinics/American Collage of Rheumatology Damage Index (SDI)). Finally, we compared the SLE-related characteristics of patients with and without tattoos. Results Twenty-eight patients (19%, 26 women, median (interquartile range) age 33 (25–42) years, 65 tattoos in total) had ≥1 tattoo. At the time the tattoo was done the median (interquartile range) SLEDAI and SDI were 2 (0–2) and 0 (0–1), respectively. The characteristics of the tattoos were similar to those of controls. No patients experienced acute complications. After a median follow-up of 17 (12–20) months (3 (2–4) visits/year) four patients had five mild-to-moderate flare-ups. The median time between the tattoo and the flare-up was 9 (6–14) months. No increase in SDI was observed. The SLE-related characteristics of patients with and without tattoos were similar. Conclusion Tattoos seem to be safe in SLE patients with inactive or low active disease.

Abstract
The aim of this study was to assess the possible association between the p53 suppressor gene codon 72 polymorphism and systemic lupus erythematosus (SLE). Our study population consisted of 513 SLE patients and 567 healthy controls. All the individuals were of Spanish Caucasian origin. Genotyping of the p53 codon 72 polymorphism was performed by allele-specific PCR. No statistically significant differences were observed between SLE patients and healthy controls when p53 codon 72 genotype and allele frequencies were compared. In addition, no evidence for association with clinical subfeatures of SLE was found. In conclusion, the p53 codon 72 polymorphism associated with SLE in a Korean population does not appear to play a major role in the susceptibility or severity of SLE in the Spanish population.

Abstract
We evaluated the influence of the hereditary make-up on the development of systemic lupus erythematosus (SLE) in two ethnic groups [Gypsy and white Caucasian Mediterranean (WCM) populations], living in the same geographic area. We compared 81 WCM and 25 Gypsy patients with SLE. The control group consisted of 185 healthy unrelated individuals, 105 WC and 80 Gypsies. In the Gypsy population, the onset of SLE occurred at earlier ages than in the other ethnic group (25.9 versus 32.0 years, P = 0.02), and showed lower SLEDAI peak values (4.9 versus 7.0, P = 0.016). The frequency of joint, kidney, gastrointestinal and eye involvement was significantly lower in Gypsy patients. In contrast, SLE-associated antiphospholipid syndrome, thrombosis and livedo reticularis were more frequent in Gypsies than in the majority ethnic group (WCM). In WCM patients, DRB1*1303- DQB1*0301 haplotype was associated with SLE ( P = 0.001, Pc = 0.038). We found SLE to be associated with DR5 ( P = 0.006, Pc = 0.05) in the Gypsy population as well as a protective effect of DPB1*0401 when DR5 was not present ( P = 0.008, Pc = 0.032). In conclusion, we found some clinical differences between WCM and Gypsy patients with SLE. Furthermore, HLA associations between HLA-DRB1-DQB1 and SLE were different for Gypsy people.

Abstract
Cat scratch disease is an infectious disorder transmitted by cats that typically affects children and young adults. Immunosuppression is a well-known risk factor for the development of severe and atypical forms of the disease; hence it is under-diagnosed in patients with compromised immunity. We are reporting the first case of cat scratch disease, which presented as fever and fatigue, in a patient with systemic lupus erythematosus while receiving immunosuppressant therapy after a kidney transplant.

Abstract
Objective The objective of this paper is to examine if there is an association between low levels of 25-hydroxyvitamin D (25(OH)D) and insulin resistance (IR) in nondiabetic women with systemic lupus erythematosus (SLE) and to evaluate its impact on arterial stiffness. Patients and methods In this cross-sectional study 25(OH)D, insulin, insulin resistance measured by the homeostatic model assessment (HOMA-IR), homocysteine, fibrinogen, characteristics of SLE, medications and pulse-wave velocity (PWV) were measured in 106 nondiabetic women with SLE and 101 matched controls. Results Women with SLE tended to have lower 25(OH)D levels ( p = 0.078) and a higher frequency of 25(OH)D deficiency (defined as <10 ng/ml) than controls ( p = 0.058). Patients from the lowest quartile of the 25(OH)D range had higher PWV ( p = 0.043), fasting glucose ( p = 0.035), insulinemia ( p ≤ 0.001), HOMA-IR ( p = 0.006), C4 ( p = 0.012), as well as more frequent IR ( p = 0.002) and metabolic syndrome ( p = 0.052) than those in the upper quartile, and no differences were found in age, body mass index (BMI), blood pressure, lipid levels and renal function. In women with SLE, 25(OH)D inversely correlated with insulin ( p = 0.006), HOMA-IR ( p = 0.008) and C4 ( p = 0.048) and tended to correlate with fibrinogen ( p = 0.060) after adjustment for BMI, age, SLEDAI, prednisone dose, renal function, inflammation markers and seasonal variation, but not with PWV. In controls, 25(OH)D correlated only with homocysteine after the same adjustment, and the correlation with PWV tended to be significant after adjustment for BMI and age ( r = −0.190, p = 0.10). Conclusion Low 25(OH)D levels were found to be associated with increased IR in nondiabetic women with SLE independently of BMI. Low 25(OH)D levels, but not IR, could be associated with increased arterial stiffness in these patients.

Abstract
A 65-year-old woman with bullous pemphigoid presented with fever and several red-purple nodular subcutaneous lesions on both lower legs 1 week after starting treatment with azathioprine (AZA). Biopsy of a skin nodule was compatible with erythema nodosum (EN) and hypersensitivity reaction to AZA was suspected. AZA was subsequently discontinued, observing complete remission of fever and EN within 2 weeks. This case highlights the importance of recognizing EN as a possible manifestation of hypersensitivity reaction to AZA.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease in which increased apoptosis and decreased apoptotic cells removal has been described as most relevant in the pathogenesis. Long-chain acyl-coenzyme A synthetases (ACSLs) have been involved in the immunological dysfunction of mouse models of lupus-like autoimmunity and apoptosis in different in vitro cell systems. The aim of this work was to assess among the ACSL isoforms the involvement of ACSL2, ACSL4 and ACSL5 in SLE pathogenesis. FINDINGS With this end, we determined the ACSL2, ACSL4 and ACSL5 transcript levels in peripheral blood mononuclear cells (PBMCs) of 45 SLE patients and 49 healthy controls by quantitative real time-PCR (q-PCR). We found that patients with SLE had higher ACSL5 transcript levels than healthy controls [median (range), healthy controls = 16.5 (12.3-18.0) vs. SLE = 26.5 (17.8-41.7), P = 3.9×10 E-5] but no differences were found for ACSL2 and ACSL4. In in vitro experiments, ACSL5 mRNA expression was greatly increased when inducing apoptosis in Jurkat T cells and PBMCs by Phorbol-Myristate-Acetate plus Ionomycin (PMA+Io). On the other hand, short interference RNA (siRNA)-mediated silencing of ACSL5 decreased induced apoptosis in Jurkat T cells up to the control levels as well as decreased mRNA expression of FAS, FASLG and TNF. CONCLUSIONS These findings indicate that ACSL5 may play a role in the apoptosis that takes place in SLE. Our results point to ACSL5 as a potential novel functional marker of pathogenesis and a possible therapeutic target in SLE.

Abstract
Objective: The aim of the study was to determine the clinical and psychological factors linked to health-related quality of life (HRQOL) in patients with systemic lupus erythematosus (SLE) and test the effectiveness of cognitive behavioural therapy in changing these factors. Methods: We evaluated 34 patients with SLE over a period of 15 months. In order to study the variables related to items of QOL and the physical (PCS) and mental (MCS) component summaries of the SF-36, several multiple linear regression models were constructed. Patients were randomized and distributed into two similar groups; one of them received cognitive behavioural therapy and the other received the usual controlled care. The psychological aspects as well as the related-disease factors were evaluated four times during the study. Results: Self-perceived stress (R2 corrected: 0.314, t: -2.476, p < 0.021), vulnerability to stress (R2 corrected: 0.448, T: -2.166, p < 0.04) and anxiety (R2 corrected: 0.689, T: -7.294, p < 0.00) were predictor variables of MCS. The group of patients who received the therapy improved their level of physical role functioning, vitality, general health perceptions and mental health, compared with the group of patients who only received conventional care. Conclusion: QOL usually depends on multiple factors, some of which are stress and anxiety, which can be modified by a cognitive behavioural therapy, in order to obtain a significant improvement in the HRQOL, irrespective of the activity level of the disease. Frequent evaluations of the quality of life in patients with SLE and psychological treatment should also be considered. Lupus (2010) 19, 1632—1639.

Abstract
OBJECTIVES To determine the effect of low (< or =7.5 mg/day; LD-PRD group) or medium (>7.5 mg/day; MD-PRD group) doses of prednisone over the past 4 months on insulin levels and insulin resistance (IR) in SLE patients. METHODS SLE patients were categorised in prednisone non-users (No PRD) (n=41), LD-PRD (n=71) and MD-PRD (n=16) users. We compared insulin levels, presence of increased IR using homeostasis model assessment (HOMA index), metabolic syndrome (MetS), and other clinical, metabolic and inflammatory parameters in the 3 groups. A Spearman's rho test was used to identify independent associations between daily prednisone dose, HOMA index and insulin levels and other parameters, after adjusting for confounders. RESULTS No differences in increased IR, HOMA index and insulin between No PRD and LD-PRD were found. In contrast, the MD-PRD group was younger (p=0.001) and had higher insulin (p=0.015), higher HOMA index (p=0.019) and increased IR (OR 5.8, 95% CI (1.7-20), p=0.007) in comparison with the LD-PRD group. The HOMA index strongly correlated with body mass index (BMI) (rs=0.460, p<0.001) but not with clinical activity or inflammatory state after adjusting for confounders. Prednisone dose correlated with the HOMA index and insulin but not with inflammatory parameters (erythrocyte sedimentation rate p=0.075) after adjusting for confounder. CONCLUSIONS Daily medium-dose prednisone use (>7.5 mg/d) but not low-dose (< or =7.5 mg/d) use increased insulin levels and IR in SLE, which may contribute to increased CV risk experienced by these patients.

Abstract
The objective of this article was to evaluate whether serum uric acid (SUA) correlates with arterial stiffness and inflammation markers in a cohort of women with systemic lupus erythematosus (SLE) without overt atherosclerotic cardiovascular diseases, who attended a community hospital. One hundred and two women with SLE were assessed as part of this cross-sectional study. Carotid-femoral pulse wave velocity (PWV) was measured using an automatic device (Complior). C-reactive protein (CRP), fibrinogen and homocysteine levels as well as other metabolic results were recorded. Duration and activity of SLE, damage accrual and treatments were recorded. SLE women were categorized as having or not having hyperuricaemia (HU) according to SUA levels (greater than or up to 6.2 mg/dl, respectively). A multiple linear regression analysis was used to determine the independent link between SUA levels and other variables. Women with SLE and HU (n = 15, 15%) had a worse cardiovascular risk profile that included ageing, hypertension, obesity, higher total cholesterol levels, renal failure and presence of metabolic syndrome. Also, the duration of SLE was increased and damage accrual was greater. In the unadjusted analysis, SUA levels correlated with PWV, CRP, fibrinogen and homocysteine. However, in a multivariate linear regression analysis, SUA levels independently correlated with the duration of SLE, creatinine, total cholesterol and homocysteine levels but did not correlate with PWV. In conclusion, SUA was associated with arterial stiffness, but not independently of age and homocysteine levels. Nevertheless, SUA might be an ancillary indicator of subclinical atherosclerosis in SLE women without clinically evident atherosclerotic cardiovascular disease.

Abstract
To determine the "in-vitro" intrinsic cell radiosensitivity (RS) as a risk indicator of radiation-related side-effects in patients with systemic lupus erythematosus (SLE) compared with healthy subjects (control group). Moreover, we elucidated if clinical, therapeutic and biological parameters could affect the "in-vitro" intrinsic RS in patients with SLE. Intrinsic RS was determined by the quantification of the initial radiation-induced DNA double-strand breaks in peripheral lymphocytes, measured by pulsed-field gel electrophoresis from 52 patients with SLE and a control group consisting of 48 sex- and age-matched healthy subjects. No difference in intrinsic RS was found among both groups. However, SLE patients with anaemia, increased erythrocyte sedimentation rate and those with positive result for anti-La/SSB and anti-RNP antibodies showed significantly higher DNA double-strand breaks than those without them. In our study, patients with SLE did not have a higher intrinsic RS than healthy subjects. According to these results, and with the caution of being a limited laboratory study, the use of radiotherapy should not be avoided in patients with SLE when it is clinically needed.

Abstract
The aim of this study was to determine the potential role of three IRF3 gene polymorphisms (rs2304204, rs7251 and rs2304207) with systemic lupus erythematosus (SLE). Our study population consisted of 610 patients with SLE and 730 healthy controls. All individual were of Spanish Caucasian origin. The IRF3 polymorphisms were genotyped using a PCR system with pre-developed TaqMan allelic discrimination assay. No statistically significant differences were found when allele and genotype distribution of rs2304204, rs7251 and rs2304207 polymorphisms were compared between patients with SLE and controls [overall P values: rs7251, P = 0.06; rs2304204, P = 0.26 and rs2304207, P = 0.36, by chi-squared test on a 3 x 2 contingency table. Overall allelic P values: rs7251, P = 0.8, OR (95%CI) = 1.03 (0.87-1.22); rs2304204, P = 0.2, OR (95%CI) = 1.12 (0.93-1.34) and rs2304207, P = 0.8, OR (95%CI) = 1.02 (0.82-1.26)]. In addition, no evidence of association with haplotypes and clinical features of SLE was found. Our data suggest that the IRF3 polymorphisms do not appear to play a major role in the susceptibility or severity of SLE in a Spanish population.

Abstract
OBJECTIVES The aim of this study was to evaluate the relevance of genetic variants of TLR5 (rs5744168) and TLR7 (rs179008) gene in systemic lupus erythematosus (SLE) in a Spanish population. MATERIAL AND METHODS Our study population consisted of 752 SLE patients and 1107 healthy controls. All individual were of Spanish Caucasian origin. The TLR5 and TLR7 polymorphisms were genotyped using a PCR system with pre-developed TaqMan allelic discrimination assay. RESULTS No statistically significant differences were observed when the allele and genotype distribution of TLR5 rs5744168 and TLR7 rs179008 polymorphisms was compared between SLE patients and healthy controls. A significant increase frequency in the CC genotype of the TLR5 rs5744168 polymorphism among SLE patients without nephritis was found (93% vs. 87% in SLE patients with nephritis, p=0.03, OR=2.11 95%CI 0.93-3.51). However, this difference did not reach statistical significance in the allele frequencies (p=0.08). CONCLUSION These results suggest that the tested variations of TLR5 and TLR7 genes do not confer a relevant role in the susceptibility or severity to SLE in the Spanish population.

Abstract
The aim of this cross-sectional study was to establish the frequency, phenotype and characteristics of metabolic syndrome (MS), as defined by the Adult Treatment Panel III, in a cohort of patients with systemic lupus erythematosus (SLE) and its possible association with cardiovascular diseases (CVD). A total of 160 patients with SLE and 245 age, sex, educational level and ethnically matched controls were included. Association with cardiovascular risk factors, SLE features, treatment of SLE and history of CVD were assessed in patients with SLE and controls with and without MS. MS was non-significantly increased in patients with SLE (20%) compared with controls (13%; P = 0.083). It was more commonly observed in patients with SLE ≤40 years old (15.8%) than in controls of the same age group (4.2%; P < 0.001). The mean number of MS criteria was significantly higher among patients with SLE than in controls. The frequency of CVD was also 28-fold higher among patients with SLE (11.3%) than in controls (0.4%). SLE with MS presented higher levels of inflammatory markers than SLE without MS. In a multivariate analysis, educational level, serum triglycerides, HDL-cholesterol and C3 serum levels and hydroxychloroquine use were independently associated with MS.

Abstract
The aim of this study was to evaluate the association between systemic lupus erythematosus (SLE) and polymorphisms in the interleukin-23 receptor (IL23R) gene, which have been previously found to be associated with two autoimmune diseases: inflammatory bowel disease and psoriasis. Our study includes 224 SLE patients and 342 healthy controls. The genotyping of IL23R variants was carried out using a polymerase chain reaction system with predeveloped TaqMan allelic discrimination assays. No statistically significant differences were observed between SLE patients and healthy controls with any of the IL23R genetic variants. In addition, we did not find any significant differences when we stratified SLE patients according to their clinical and demographic features. These results suggest that IL23R polymorphisms do not appear to play an important role in the susceptibility or severity of SLE in the Spanish population.

Abstract
The aim of this study was to evaluate the potential association of functional polymorphisms of macrophage migration inhibitory factor with systemic lupus erythematosus. Our study includes 711 systemic lupus erythematosus (SLE) patients and 755 healthy controls. We genotyped the migration inhibitory factor (MIF) -173G/C using a polymerase chain reaction (PCR) system with predeveloped TaqMan allelic discrimination assay and the MIF -794 CATT(n) microsatellite polymorphism using a PCR-fluorescent method. A statistically significant difference in the distribution of the MIF -173(*)C allele between SLE patients and controls (P=0.004, OR=1.34, 95% CI=1.05-1.27) was observed. In addition, the frequency of the MIF -173(*)C/C genotype was higher in SLE patient (P=0.002, OR=2.58, 95% CI=1.32-5.10). No differences in the distribution of CATT(n) were found. However, the haplotypes analyses showed that only the CATT(7)-MIF -173(*)C haplotype was associated with a higher susceptibility to SLE (P=0.001, OR 1.84, 95% CI 1.35-2.79). No association with clinical features was detected in any case. These results suggest that both, MIF -173(*)C allele and CATT(7)-MIF -173(*)C haplotype, confer susceptibility to SLE in our population.

Abstract
BASIS A significant proportion of our patients has described to have problems from tolerance to Dolquine, a new presentation of hydroxychloroquine recently marketed in Spain, compared to Plaquenil. The objective was to know the tolerability and the adverse effects of this new presentation. PATIENTS AND METHOD A cross-sectional multicenter study on 133 patients treated with Dolquine was conducted. RESULTS Of the 133 patients (87% women; average age [AA]: 32.9 [15.4] years) who received Dolquine during an average period of 6.7 (1.4) months, 32 patients (24%) described to have more problems with this drug in comparison with other antimalarial. The adverse effects experienced were: bitter taste (62.4%), difficulty in swallowing the tablet (13.5%), dyspepsia (9.8%), nausea (7.5%), vomiting (1.5%), pruritus (1.5%), diarrhea (0.7%), and instability feeling (0.7%). The presence of gastrointestinal adverse effects was not related to the consumption of gastroerosive drugs, gastric protectors, or a high number of drugs. The attrition rate was 9.8%. Conclusions. Dolquine induces lower tolerance and more gastrointestinal adverse effects than Plaquenil, pointing out its bitter taste and the difficulty in swallowing it. Despite this higher intolerance there was not an increase in the attition rate from the antimalarial treatment in comparison to other series.

Abstract
The etiological role of hair dye treatment (HDT), some of them such as permanent hair dyes containing aromatic amines, in the development of SLE has been previously ruled out. However, the possible influence of HDT use on the course and prognosis of lupus patients has been assessed only in one short-term study. Since HDT is very extensive among the population, the knowledge of this possible negative effect may be very important. Thus, the aim of this study was to assess the long-term influence of several HDTs on the course and clinical severity of patients with both systemic lupus erythematosus (SLE) and cutaneous lupus (CL). In this longitudinal case series study, 91 SLE patients and 22 CL patients were prospectively studied from October 1988 to May 2000. They were divided into three groups: (a) non-HDT users--patients who have never used HDT (n = 65); (b) P-HDT users--HDT permanent type users, alone or in combination with other types of HDT (n = 28); (c) non P-HDT--users of other treatments different from permanent tinting (bleach, lowlights, etc; n = 20). In each patient we determined: (1) number of flares/year in SLE patients and worsening of cutaneous lesions for CL; (2) Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) damage index; (3) predominant damaged organs/systems according to the HDT use and type of HDT; and (4) subjective impression about the disease evolution in relation to HDT use. No significant differences were found with respect to flares/year and SLICC/ACR damage index between the study groups. Non-HDT group presented more renal involvement and serositis than both HDT-user groups. No patient related the HDT use to the worsening of his disease. Therefore, in this study no evidence of an association between the long-term use of several types of HDT and the clinical activity and course of SLE and CL was found.

Abstract
PURPOSE To report a Takayasu's arteritis (TA) case with an intense ocular involvement and the response to monthly bolus of Cyclophosphamide. METHODS Case report and literature review. RESULTS Cyclophosphamide was useful to improve the TA symptoms without any additional treatment and any secondary effects. When this therapy was discontinued the ocular symptoms progressed. CONCLUSION Although no definitive therapy has been established, Cyclophosphamide intravenous bolus may be useful to improve ocular symptoms of Takayasu's Arteritis, specially in early stages. There are not adequate descriptions in the literature concerning the effect of this treatment on the ocular manifestations of TA.

Abstract
Vascular reactivity to vasoconstrictors in relation to altered thyroid function was studied in two preparations: aortic strips and the isolated perfused kidney. To assess whether the possible alterations in vascular reactivity were restricted to a specific agonist or whether they involved the contractile system, receptor-mediated and nonspecific smooth muscle stimulants were used. Male Wistar rats were divided into three groups: control, hyperthyroid and hypothyroid rats. Aortic strips from hypothyroid rats were less sensitive to phenylephrine and KCl when the data were expressed in absolute values or as percentages of the maximum responses. Sensitivity and reactivity in strips from hyperthyroid rats were similar to those observed in control strips. Renal vasculature obtained from hypothyroid rats also showed a markedly reduced sensitivity to phenylephrine, with normal maximal responses. The response to vasopressin at 3-10(-11) mol/l was also decreased, as was the reactivity to barium chloride. In contrast, renal vasculature of hyperthyroid rats showed markedly enhanced reactivity to all agonists: the concentration-response curves were characterized by a similar threshold and a greater maximal response. These results demonstrate that hypothyroidism is accompanied by a marked decrease in sensitivity to vasoconstrictors in large arteries as well as in resistance vessels. This decrease may be secondary to a generalized alteration in the contractile system of vascular smooth muscle cells and may play a role in the decreased blood pressure in these animals. In contrast, isolated perfused kidneys of hyperthyroid rats showed increased vascular reactivity to vasoconstrictors, which may play a role in the maintenance of elevated blood pressure in these animals.

Abstract
1. Renal responses to changes in renal perfusion pressure were studied in anaesthetized hyperthyroid (thyroxine, 300 micrograms day-1 kg-1) and hypothyroid (methimazole, 0.03% via drinking water) rats to determine whether an abnormality in the pressure-diuresis-natriuresis phenomenon is involved in the resetting of kidney function in these disorders. 2. There were no significant differences between control and hypothyroid rats with respect to the relationships between renal perfusion pressure and absolute or fractional water and sodium excretion. However, in hyperthyroid rats the pressure-diuresis-natriuresis mechanism was impaired. 3. Renal blood flow and glomerular filtration rate were well autoregulated and there were no differences between control and hypothyroid rats at every level of renal perfusion pressure. A significantly lower glomerular filtration rate was observed in hyperthyroid rats when data were expressed per gram kidney weight, but glomerular filtration rate was similar to that of control rats when normalized by body weight. 4. The shift in the pressure-diuresis-natriuresis response of hyperthyroid rats is mainly due to an increase in tubular reabsorption. Blunting of the renal pressure-diuresis-natriuresis mechanism in hyperthyroid rats may represent the functional resetting of the kidney necessary for sustained hypertension. However, a normal pressure-natriuresis response was observed in hypothyroid rats, in which blood pressure was markedly reduced.

Abstract
We assessed the effects of the inhibition of endogenous nitric oxide (NO) synthesis with Nw-nitro-L-arginine methyl ester (L-NAME) on water and sodium handling after NaCl load containing the inhibitor at 0, 0.5, 5 and 50 mg/kg in conscious control, hyper- and hypothyroid rats. L-NAME at 0.5 mg/kg caused a similar decrease in diuresis and natriuresis in control and hypothyroid rats, whereas no changes were seen in the hyperthyroid group. The saline load with 5 mg/kg of L-NAME produced no significant changes with respect to the 0 dose in any variable in control and hypothyroid rats, but increased natriuresis in the hyperthyroid group. The highest dose of L-NAME (50 mg/kg) increased the diuretic and natriuretic response in control and hyperthyroid groups, whereas in the hypothyroid group no urinary variable was significantly modified with respect to the 0 dose. These results indicate that the antidiuretic and antinatriuretic effects of L-NAME at low doses are suppressed in hyperthyroid rats, whereas the diuretic and natriuretic effects at high doses are absent in hypothyroid rats. Our findings suggest that the modulatory role of NO on sodium and water excretion is affected in both thyroid disorders. In addition, the highest dose of L-NAME killed hyperthyroid rats, indicating that NO plays an essential role for life in hyperthyroidism.

Abstract
1. N omega-nitro-L-arginine methyl ester (L-NAME), an inhibitor of NO biosynthesis, which blocks basal NO production, caused a similar increase of mean arterial pressure (MAP) in control hyper- and hypothyroid rats at the lowest dose, however, smaller pressor effects were observed with increasing doses in hyper- and hypothyroid rats. An additional dose of L-NAME (30 mg/kg), which produced no further increase in pressure, killed 90% of the hyperthyroid rats, whereas hypothyroid and control rats survived this additional dose. 2. The systemic responses to acetylcholine (ACh), an endothelium-dependent vasodilator that stimulates NO production/release, were significantly increased in hypothyroid rats, while hyperthyroid rats showed no significant differences when compared with controls. However, 10(-8) M ACh killed hyperthyroid rats, whereas control and hypothyroid rats survived this dose. 3. The maximal hypotensive response to sodium nitroprusside (SNP), an agonist that generates NO, was similar in intact controls, hyper- and hypothyroid rats. 4. These data indicate that hyper- and hypothyroidism show a reduction in basal NO synthesis/release, this reduced systemic NO tone being essential for life in hyperthyroid rats; whereas the response to ACh is not reduced and the hypotensive response to SNP did not differ between groups, indicating that the responsiveness of the systemic circulation to NO is not altered in either thyroid disorder.

Abstract
OBJECTIVE The aim was to evaluate the contribution of nitric oxide (NO) and endothelium derived hyperpolarising factor (EDHF) to the endothelium dependent, acetylcholine induced vasodilatation in isolated perfused rat kidney. METHODS The renal response to acetylcholine was compared in phenylephrine preconstricted renal vasculature under basal conditions and after the infusion of N omega-nitro-L-arginine (L-NAME), an inhibitor of NO synthesis, and tetraethylammonium, a non-specific blocker of potassium channels that inhibits acetylcholine induced hyperpolarisation. These inhibitors were given alone and together. In another experiment, the renal response to acetylcholine was compared when the vasculature was preconstricted with phenylephrine or with 40 and 80 mM KCl under basal conditions and after the infusion of L-NAME. All experiments were done in the presence of indomethacin. RESULTS Inhibition of NO generation with L-NAME reduced the vasodilator responses to acetylcholine by approximately 50%, and enhanced the response to sodium nitroprusside in the isolated perfused kidney preconstricted with phenylephrine. Infusion of tetraethylammonium also decreased the response to acetylcholine by approximately 50% and increased vasodilatation responses to sodium nitroprusside. The simultaneous administration of both inhibitors (L-NAME and tetraethylammonium) had a summational effect which almost completely suppressed acetylcholine induced vasodilatation. Increasing concentrations of extracellular potassium produced a dose related decrease in acetylcholine induced vasodilatation. These attenuated responses were almost abolished after the infusion of L-NAME. CONCLUSIONS Our results suggest that the vasodilator response to acetylcholine in isolated perfused rat kidneys is subserved by EDHF and nitric oxide, both endothelium derived mediators participating to a similar extent.

Abstract
We have evaluated the renal blood flow (RBF) response of cirrhotic rats to endothelium-dependent [acetylcholine (ACh)] and -independent [sodium nitroprusside (NP)] vasodilators. In anesthetized rats, ACh dose dependently increased RBF, but the response of the cirrhotic rats (n = 6) was significantly higher than that of the controls (n = 6). NP also increased RBF in a dose-dependent manner, but there were no differences between both groups. NG-nitro-L-arginine methyl ester (L-NAME; 10 mg/kg i.v.) significantly reduced the responses to ACh in both groups, but those of the cirrhotic rats were still higher than those of the controls. In experiments performed in isolated perfused kidneys, preconstricted with phenylephrine, dose-response curves for ACh and NP were obtained in the presence of indomethacin. Both ACh and NP decreased renal perfusion pressure dose dependently, but only the response of the cirrhotic rats (n = 5) to ACh was significantly higher than that of the controls (n = 5). L-NAME (100 microM) significantly reduced the responses to ACh and increased those of NP and abolished the differences between groups, except at the high dose of ACh. These results demonstrate an elevated endothelium-dependent vasodilator response in the cirrhotic kidney, which is eliminated by combined prostaglandin and nitric oxide (NO) synthesis inhibition and suggest that increased intrarenal activity of NO may be contributing to the renal alterations of liver cirrhosis.

Abstract
We used flow cytometry to compare the effects of whole cells and capsular polysaccharides of Klebsiella pneumoniae on the phagocytic ability ot polymorphonuclear leukocytes. Our results showed a light decrease in phagocytic activity in the presence of capsular polysaccharides, but a marked decrease with whole cells. Our findings suggest that the resistance to phagocytosis in these microorganisms is not due exclusively to their capsule, as claimed by other authors.

Abstract
1. The present study was undertaken to test whether insulin acts as a pressor agent and causes hypertension in rats. 2. Insulin at doses of 10 or 100 units day-1 kg-1 was administered daily by subcutaneous injection to normal rats for 6 weeks. As it has been suggested that sodium retention plays a major role in the putative hypertensive activity of this hormone, insulin was also administered to saline- (1% NaCl) drinking rats according to the same protocol. Water- and saline-drinking rats served as controls. 3. After 6 weeks of insulin treatment, the mean arterial blood pressure did not increase in any of the insulin-treated or the insulin-salt-treated groups. However, in both insulin-salt-treated groups, absolute and relative ventricular and renal hypertrophy with increased ventricular water content as well as increased urine output with reduced osmolality were observed. 4. All insulin-treated groups showed increased plasma levels of glucose, insulin and antidiuretic hormone when compared with their respective controls. 5. These results demonstrate that chronic insulin treatment did not increase blood pressure in rats, even when drinking water was supplemented with NaCl, and suggest that a polyuria-polydipsia syndrome was present in both insulin-salt-treated groups. Moreover, increased plasma levels of antidiuretic hormone were observed in all insulin-treated groups.

Abstract
The number of beta-adrenoceptors was measured in cardiac and renal cortex membranes from controls and thyroxine-treated rats. Two methods of membrane preparation (sucrose- and KCl-extraction) were compared. KCl-extraction yielded a higher number of beta-adrenoceptors, accompanied by increased activity of the plasma membrane enzyme marker 5'-nucleotidase. Thyroxine increased the number of beta-adrenoceptors in both cardiac and renal cortex membranes prepared with both methods. These results suggest that: i) Enrichment of the membrane fraction may explain the higher number of beta-adrenoceptors found with KCl, ii) Thyroid hormone plays a role in the regulation of beta-adrenoceptors in the renal cortex.
