Abstract
Introduction Cardiovascular risk seems not to be greater in patients with white coat uncontrolled hypertension (WUCH) than in patients with sustained blood pressure (BP) control. Therefore, its detection is important to avoid overtreatment. The COVID-19 pandemic determined a massive migration of hypertension consultations from the face-to-face modality to teleconsultations, and it is unknown whether WUCH exists in this context. Aim We aimed to evaluate the prevalence of WUCH through home BP monitoring (HBPM) in treated hypertensive patients evaluated by teleconsultation. Methods We included treated hypertensive patients that owned a digital BP monitor. During teleconsultation, patients were asked to perform two BP measurements and then a 7-day HBPM, using the same device. Patients were classified as having WUCH if BP was ≥ 140 and/or 90 mmHg in teleconsultation and < 135/85 mmHg on HBPM. The prevalence of WUCH and its 95% confidence interval were estimated. One-way ANOVA, the Chi-square test or Fisher’s exact test were used to compare the characteristics of these patients with the other groups. Results We included 341 patients (45.2% male, mean age 62.3 years). The prevalence of WUCH was 33.1% (95% CI 28.3–38.3%). Significant differences were found in terms of age, the number of antihypertensive drugs and the use of calcium channel blockers, all lower in the WUCH group as compared with the groups with elevated BP on HBPM. Conclusion WUCH exists in teleconsultation and is very frequent. It can be easily detected though HBPM, thus avoiding overmedication, and its potential impact on side-effects and health costs.

Abstract
BACKGROUND Currently, total hyperhomocysteinemia (tHHcy) is a well-known condition linked to a higher risk of vascular disease. Prevalence of HHcy increases in elderly persons as the risk associated with it persists. Because factors can be potentially reduced in the elderly, it is important to carry out epidemiologic studies of HHcy. PROCEDURE Previously we described the prevalence of hypertension control in an elder population; now, in an observational cross-sectional simple blind study, total homocysteine (tHcy) concentration was determined in 196 of 400 patients from the original cohort. RESULTS Mean Hcy concentration was 13.2 ,amol/L (95% confidence interval 12.4-14.0; range, 5.0 to 48.9); 15.0 ,imol/L for men and 12.3 pAmol/L for women. Mean serum folic acid levels were 4.9 + 3.1 ng/mL (range, 2.0 to 20.0 ng/mL), and vitamin B12 levels were 384.8 314.1 pg/mL (range, 48.0 to 1500.0 pg/mL). Taking into account the reference values established by the Third National Health and Nutrition Examination Survey III study, HHcy was detected in 69.8% of all the subjects evaluated. The study showed that 76.2% of the men and 66.4% of the women had high Hcy levels. CONCLUSIONS The very high prevalence of tHHcy in the elderly population, and the consequent risks associated with it suggest that although there are no trials that effectively prove the benefit of tHcy decrease, nutritional intervention is still justified.

Abstract
The outcome of acute renal failure due to diarrhea-associated hemolytic uremic syndrome (D+ HUS) is generally predicted to be good. However, there are only a few long-term observations with detailed reports on long-term sequelae. Specifically, adequate long-term blood pressure (BP) evaluations are scarce. The present study evaluated BP in pediatric patients after childhood D+ HUS. The study group comprised 28 patients (20 males) aged 6-23.5 years (median 10.1 years). All patients had a history of D+ HUS at a median age of 1.1 years (range 0.5-6 years). Based on the duration of oliguria and/or anuria, the primary disease was classified as mild (n=6), moderate (n=6), or severe (n=16). The BP in these patients was studied at a median time of 8.4 years (range 2.3-22.9 years) after manifestation of D+ HUS by means of office BP measurements and 24-h ambulatory BP monitoring (ABPM) using a Spacelabs 90207 oscillometric monitor. Measurements were compared with normal values of published standards for healthy children and adolescents. Conventional office BP measurements were above the 95th percentile in 1 patient. By ABPM, 2 patients were diagnosed to have mean systolic daytime and nighttime values in the hypertensive range, and systolic and diastolic hypertension was confirmed in the first patient. All these patients had a severe form of D+ HUS in the past. By applying ABPM, BP anomalies were detected in 5 additional patients. Elevated systolic BP loads were found in 4 patients, and daytime systolic and diastolic hypertension in the other 1. At the time of the study, 2 of them were classified as "recovered." The late outcome of D+ HUS may be worse than anticipated. BP anomalies as long-term sequelae of D+ HUS could be identified by ABPM but not by office BP measurements. These findings may represent an isolated sign of residual renal disturbance.

Abstract
BACKGROUND High total plasma homocysteine (tHcy) levels are accompanied by an increased risk for premature development of atherosclerosis and atherothrombosis. Adult renal transplant recipients have elevated tHcy levels. Corresponding data in pediatric, adolescent, and young adult renal transplant recipients are scarce. We investigated whether tHcy levels were elevated in stable renal transplant recipients who received kidney grafts before age 18. METHODS This cross-sectional study was conducted during routine posttransplantation follow-up. Fasting tHcy levels, serum creatinine, and lipoprotein profile were measured in 38 clinically stable renal transplant recipients with different degrees of renal function. No patient was receiving B vitamin or folic acid supplementation. Estimated glomerular filtration rate (GFR) was assessed according to Schwartz's formula. All patients followed a triple-drug immunosuppressive regimen, with the exception of three patients (deflazacort and azathioprine). Forty-one apparently healthy subjects constituted the control group. tHcy levels were determined by fluorescence polarization immunoassay in an IMx analyzer. RESULTS Mean tHcy levels in transplant recipients were significantly higher than in controls (16.8+/-8.7 micromol/L and 9.5+/-2.3 micromol/L, respectively; P<0.01). A significant positive correlation between tHcy and serum creatinine levels was observed for both transplant recipients (rS=0.70, P<0.01) and controls (rS=0.54, P<0.01). In transplant recipients, tHcy correlated negatively with estimated GFR (rS=[minus]0.47, P<0.05). Fasting tHcy levels in excess of 14.6 micromol/L (>95th percentile in controls) were present in 19 (50%) patients; 14 of these patients had an estimated GFR<60 ml/min per 1.73 m2. When the renal transplant recipients were analyzed by renal function, mean tHcy was significantly higher in patients with an estimated GFR<60 ml/min per 1.73 m2 compared with patients with an estimated GFR> or =60 ml/min per 1.73 m2 (20.5+/-9.9 vs. 13.2+/-5.8 micromol/L, P<0.01). Both groups were significantly different from controls (P<0.01). No relationship was found between tHcy level and either cumulative cyclosporine or cumulative methylprednisone doses. No differences were observed in tHcy levels or lipoprotein profile between patients who were receiving deflazacort and those on methylprednisone. CONCLUSIONS Hyperhomocysteinemia in renal transplant recipients is a common condition. Testing for fasting tHcy level might be a useful tool to identify patients at increased risk for development of vascular disease.

Abstract
The prevalence of HLA-DR4 in relation to age at disease onset was calculated in 226 consecutive female patients with definite or classical rheumatoid arthritis (RA). A slight increase in the prevalence of DR4 with age at RA onset was found. This appeared to be due to the low percentage of rheumatoid factor (RF) positivity in the youngest age groups; the DR4 prevalence in the RF positive patients was constant for all decades--that is, approximately 60%. A previously reported declining trend of DR4 prevalence in women with RA in relation to age of RA onset may be due to the disease heterogeneity of the patients included in that study.
