RESUMEN

The objectives of this study were 1-to evaluate the prevalence of masked chronic hypertension in pregnant women classified as gestational hypertension 2-to compare the risks of developing preeclampsia in true gestational hypertension vs those women classified as having gestational hypertension but who had had masked hypertension in the first half of pregnancy. We conducted a cohort study in consecutive high-risk pregnancies who were evaluated before 20 weeks of gestation. Women who developed gestational hypertension (normotension in the office before 20 weeks of gestation and office BP ≥ 140/90 mmHg and/or antihypertensive treatment in the second half of gestation) were divided, according to an ABPM performed before 20 weeks of pregnancy, in two subgroups: subgroup 1-if their ABPM was normal, and subgroup 2-if they had masked chronic hypertension. Risks for preeclampsia (PE) were estimated and compared with normotensive women. Before 20 weeks of gestation, 227 women were evaluated (age 32 ± 6 years, median gestation age 15 weeks); 67 had chronic hypertension (29.5%). Of the remaining 160, 39 developed gestational hypertension (16 in subgroup 1 and 23 insubgroup 2. Compared with normotensive pregnant women, subgroup 1 of women with gestational hypertension did not increase the risk of developing PE (OR = 0.76, 95% CI = 0.16-6.65). Conversely, subgroup 2 of gestational hypertension increased the risk of PE more than 4 times (0R = 4.47 CI = 1.16-12.63). Risk estimation did not change substantially after the adjustment for multiple possible confounders. In conclusion, the59% of women initially diagnosed as gestational hypertensive according to current recommendations had masked chronic hypertension and a very high risk of developing PE.

RESUMEN

AIMS: To evaluate arterial stiffness indicators in people with prediabetes (PreD) and its possible pathogenesis. MATERIALS AND METHODS: Pulse wave velocity (PWV) was measured in 208 people with FINDRISC ≥ 13 (57 ± 8 years old, 68.7% women) and thereafter divided into those having either normal glucose tolerance (NGT) or PreD. In each subgroup we also identified those with/out insulin resistance (IR) measured by the triglyceride/HDL-c ratio (normal cut off values previously established in our population). Clinical and metabolic data were collected for all participants. PWV was compared between subgroups using independent t test. RESULTS: Women and men had comparable clinical and metabolic characteristics with obesity (BMI ≥ 30) and antihypertensive-statin treatment, almost half with either NGT or PreD. Whereas 48% of NGT people presented IR (abnormally high TG/HDL-c ratio), 52% had PreD. PWV was significantly higher only in those with a complete picture of metabolic syndrome (MS). CONCLUSIONS: Since PWV was significantly impaired in people with a complete picture of MS, clinicians must carefully search for early diagnosis of this condition and prescribe a healthy life-style to prevent development/progression of CVD. This proactive attitude would provide a cost-effective preventive strategy to avoid CVD's negative impact on patients' quality of life and on health systems due to their higher care costs.

RESUMEN

OBJECTIVES: To estimate the prevalence of isolated nocturnal hypertension (INH) and its relationships with office blood pressure (BP) categories defined by 2018 ESC/ESH guidelines. METHODS: We conducted a prospective cohort study in consecutive patients referred to perform an ambulatory blood pressure monitoring (ABPM) for diagnosis or therapeutic purposes. Office BP measurements and ABPM were performed in the same visit. The cohort was divided according to office BP in optimal, normal, high-normal and hypertension. The prevalence and adjusted risk for combined daytime and nocturnal hypertension and INH were estimated for each category. RESULTS: We evaluated 1344 individuals, 59.3% women (51 ±â€Š14 years old) and 40.7% men (52 ±â€Š15 years old). 61.5% of the individuals had nocturnal hypertension, 12.9% INH and 48.7% combined daytime and nocturnal hypertension. Prevalence of combined daytime and nocturnal hypertension increased through office BP categories (P < 0.001). Conversely, prevalence of INH was lower in individuals with hypertension than in normotensives (7.4 vs. 17.2%, P < 0.001) and similar between nonhypertensive office BP categories, 16.6, 15 and 19.4% for optimal, normal and high-normal BP, respectively (P < 0.399). In individuals with office BP values less than 140/90 mmHg, the prevalence of masked hypertension phenotypes were 8.6, 17.2 and 30.2% for daytime, INH and combined daytime and nocturnal hypertension, respectively. Adjusted risk for combined daytime and nocturnal hypertension increased significantly through office BP categories; conversely, the risk for INH was similar in all nonhypertensive office BP categories. CONCLUSION: Nocturnal hypertension was the more prevalent phenotype of masked hypertension and more than one-third of the individuals with nocturnal hypertension had INH. The risk for INH was not related to nonhypertensive office BP categories.

RESUMEN

Hypertension is one of the main risk factors for cardiovascular disease. Functional foods containing bioactive peptides have been proposed as a strategy to decrease blood pressure (BP) in subjects under no pharmacological treatment. The aim of this study was to compare the effect of low-sodium, low-fat (LSLF) cheese and LSLF cheese containing Lactobacillus delbrueckii subsp. lactis CRL 581 (LSLF581) on BP in pre-hypertensive and stage 1 hypertensive subjects. Sixty-one pre-hypertensive and stage 1 hypertensive subjects assigned to one of twos (LSLF, n= 29 and LSLF581, n= 32) participated in this 12-month prospective, randomized, double-blind, crossover trial. Twenty-four h ambulatory BP monitoring was performed at the beginning and at the end of each four-week study period. Systolic and diastolic BP decreased in both study groups, but differences between groups were not significant (systolic, -1.78 and -0.2 mmHg; diastolic, -1.54 and -0.42 mmHg in LSLF581 and LSLF, respectively). Although our results could not support a BP lowering effect of LSLF581, small BP reductions could favorably prevent cardiovascular disease development.


La hipertensión arterial es uno de los principales factores de riesgo de enfermedad cardiovascular. Los alimentos funcionales que contienen biopéptidos constituyen una estrategia útil para disminuir la presión arterial (PA) en personas que no están bajo tratamiento farmacológico. El objetivo del estudio fue comparar el efecto de un queso bajo en sodio y bajo en grasas (BSBG) y el mismo queso con Lactobacillus delbrueckii subsp. lactis CRL 581 (BSBG581) sobre la PA en personas con prehipertensión y estadio 1 de hipertensión arterial. Realizamos un estudio prospectivo, randomizado, cruzado y doble ciego durante 12 meses en 61 personas con prehipertensión y estadio 1 de hipertensión arterial, asignadas a dos grupos: BSBG (n= 29) y BSBG581 (n= 32). Se realizó monitoreo ambulatorio de la PA (MAPA) durante 24 h al comienzo y al final de cada etapa del estudio (cuatro semanas). La PA sistólica y diastólica disminuyó en ambos grupos, aunque las diferencias entre grupos no fueron significativas (sistólica, -1.78 y -0.2 mmHg; diastólica -1.54 y -0.42 mmHg en BSBG581 y BSBG respectivamente). Aunque nuestros resultados no pueden confirmar el efecto hipotensor del queso BSBG581, las reducciones moderadas de la PA podrían prevenir el desarrollo de enfermedad cardiovascular.

RESUMEN

OBJECTIVES: To determine if there is an office blood pressure (BP) value below which out-of-office measurements are unnecessary in high-risk pregnant women. METHODS: We conducted a prospective cohort study in women in the second half of high-risk pregnancies. Office BP measurements and ambulatory blood pressure monitoring (ABPM) was performed. The cohort was divided according to quartiles of office BP and in normotension, white-coat hypertension, masked hypertension and sustained hypertension. The risks for preeclampsia/eclampsia for each category were estimated. RESULTS: Three hundred seventy-three women (30 ±â€Š7 years with 32 ±â€Š4 weeks of gestation) were included; 69 women (18.5%) developed preeclampsia/eclampsia. Risk for preeclampsia/eclampsia increased in a stepwise manner through quartiles of systolic office BP (8.8, 13.4, 19.6 and 32.3%, P < 0.001) and diastolic office BP (6.5, 13.7, 19.6 and 34,4%, P < 0.001). OR increased significantly through quartiles of systolic (P = 0.004) and diastolic (P < 0.001) office BP; the significance becomes evident between the second and third quartile, the cut-off point between these was 125/76 mmHg. Prevalence of white-coat and masked hypertension were 3.8 and 24.7%, respectively. Using ABPM, 14/61 office hypertensive women were reclassified as white-coat hypertension but 92/312 normotensive women as masked hypertension. OR for preeclampsia/eclampsia increased significantly in women with masked hypertension. Absolute risk for preeclampsia/eclampsia in women with office BP less than 125/75 mmHg was similar than that in women with normal ABPM, 7.2 and 7.1%, respectively. CONCLUSION: Masked hypertension was a prevalent and high-risk condition. Office BP at least 125/75 mmHg in the second half of gestation seems appropriate to indicate out-of-office measurements in high-risk pregnancies.

RESUMEN

OBJECTIVE: The aim of this study was to test if hypertension detected by ambulatory blood pressure monitoring (ABPM) performed at mid-pregnancy, is a useful predictor for preeclampsia/eclampsia (PEEC). METHODS: The study was performed in women coursing high-risk mid-pregnancies. Office blood pressure (BP) was estimated as the mean of three values, taken by a specialized nurse after a 15-min interview, and office hypertension defined as at least 140/90 mmHg. Immediately after, an ABPM was started. Diurnal hypertension was defined as ABPM at least 135/85 mmHg during daily activities, nocturnal hypertension as ABPM at least 120/70 mmHg during night rest. The adjusted risk of PEEC was estimated using logistic regression. RESULTS: Eighty-seven women (mean age 31 ±â€Š7 years) with 23 ±â€Š2 weeks of pregnancy were included. The prevalence of office and ABPM hypertension was 13.8 and 40.2%, respectively. The concordance between both hypertension diagnosis was low (κ = 0.170, P = 0.044). Nocturnal hypertension (35.6%) was more frequent than diurnal hypertension (26.4%). Nocturnal hypertension markedly increased the relative risk of PEEC (OR 5.32, 95% CI 1.48-19.10). The risk of PEEC attributed to diurnal hypertension did not reach statistical significance; and when both, diurnal and nocturnal hypertension were included in the same model, only the second one was a significant predictor (P = 0.012). The relative risk associated with nocturnal hypertension increased for women not taking acetylsalicylic acid (ASA); (OR 11.40, 95% CI 2.35-55.25). CONCLUSION: Nocturnal hypertension at high-risk mid-pregnancy is a frequent condition and a strong predictor for PEEC; the risk doubled for women not taking ASA.

RESUMEN

Blood pressure (BP) was assessed by patients themselves in recently published trials. Self-measured office blood pressure (SMOBP) seems particularly interesting for limited health resources regions. The aim of our study was to evaluate the relationship between SMOBP values and those estimated by ambulatory blood pressure monitoring (ABPM). Six hundred seventy-seven patients were evaluated using both, SMOBP and ABPM. The differences between SMOBP and daytime ABPM were evaluated with paired "t" test. The correlations among SMOBP and ABPM were estimated using Pearson's r. The accuracy of SMOBP to identify abnormal ABPM was determined using area under ROC curve (AUC). Sensitivity, specificity, and positive and negative predictive values were calculated for different SMOBP cut-points. Using the average of three readings, systolic SMOBP was higher (3.7 (14.2) mmHg, p < 0.001) and diastolic SMOBP lower (1.5 (8.1) mmHg, p < 0.001) than ABPM. Both BP estimates had a significant correlation, r = 0.67 and r = 0.75 (p < 0.01) for systolic and diastolic BP, respectively. Systolic SMOBP predicted systolic abnormal ABPM; the AUC were 0.80 (0.77-0.84) and 0.78 (0.74-0.81) for daytime and 24 h hypertension, respectively. Diastolic SMOBP predicted diastolic hypertension, AUC 0.86 (0.83-0.88) for both daytime and 24 h hypertension. Neither correlations nor AUCs improved significantly using the average of five readings. SMOBP ≥ 160/90 mmHg was highly specific (>95%) to identify individuals with hypertension in the ABPM; SMOBP < 130/80 mmHg reasonably discarded abnormal ABPM. In conclusion, a high proportion of individuals could be classified adequately using SMOBP, reducing the necessity of healthcare resources and supporting its utility for screening purposes.

RESUMEN

OBJECTIVE: The aim was to evaluate the relationships among insulin resistance markers and nocturnal and diurnal hypertension in normotensive or mildly untreated hypertensive adults. METHODS: The study was performed in both female and male adults referred to the Cardiometabolic Unit of the Hospital San Martín, La Plata, Argentina, in order to perform an ambulatory blood pressure measurement (ABPM) for the evaluation of a possible hypertensive disorder. The population was stratified according to their ABPM in: 1-presence or absence of diurnal hypertension and 2-presence or absence of nocturnal hypertension; both conditions were analyzed separately. Fasting plasma insulin (FPI), homeostasis model assessment of insulin resistance (HOMA-IR), and triglycerides (TG)/high-density lipoprotein cholesterol (HDL-C) ratio were used as surrogate markers of insulin resistance and compared among subjects with vs. without diurnal or nocturnal hypertension. RESULTS: One hundred and five patients, 55 women, 47 (11) years old, and 50 men, 44 (16) years old, were included. Diurnal and nocturnal hypertension were found in 60% and 64% of the sample, respectively. There were no significant differences among the levels of insulin resistance markers between individuals with or without diurnal hypertension. In contrast, individuals with nocturnal hypertension were more insulin resistant irrespectively of whether they were evaluated using FPI (P = 0.016), HOMA-IR (P = 0.019), or TG/HDL-C ratio (P = 0.011); FPI differences remained significant after adjustment for sex, age, and obesity indicators (P = 0.032). CONCLUSIONS: Nocturnal but not diurnal hypertension was related to higher levels of 3 insulin resistance markers in normotensive and untreated mildly hypertensive adults; this relationship seems partially independent of obesity.

RESUMEN

OBJECTIVE: The aim was to evaluate the prevalence of nocturnal and masked hypertension and the prognostic values of these blood pressure (BP) abnormalities in normotensive women coursing a high-risk pregnancy. METHODS: The study was performed in pregnant women with 20 or more weeks of gestation coursing a high-risk pregnancy, sent to a specialized hypertension department to perform a prospective defined protocol of BP evaluation. Women with office BP at least 140/90 mmHg were excluded. An ambulatory monitoring of BP was performed to identify masked and nocturnal hypertension (defined according to the current guidelines). The adjusted risk for development of preeclampsia/eclampsia (PEEC) was estimated using logistic regression. The ability of SBP and DBP to identify risk of PEEC was estimated using area under the receiver-operating characteristic curves. RESULTS: Eighty-seven women (29 ±â€Š7 years old, 30 ±â€Š5 weeks of pregnancy) were included in this analysis. The prevalence of masked hypertension was 33.3%. Nocturnal hypertension was found in 42.5% of the women. Remarkably, 27.0% of the women with nocturnal hypertension had normal 24-h values according to ambulatory BP monitoring. Twenty-two patients developed PEEC; adjusted relative risks increased with the presence of nocturnal (odds ratio = 4.72, 95% confidence interval 1.25-19.43, P = 0.023) or masked hypertension (odds ratio = 7.81, 95% confidence interval 2.6-22.86, P = 0.001). Nocturnal SBP and DBP had the highest abilities to predict PEEC (area under the curve = 0.77 and 0.80, respectively). CONCLUSION: Masked and nocturnal hypertension are frequent findings in normotensive women coursing a high-risk pregnancy, and their presence implies an increased risk to develop PEEC.

RESUMEN

The aim of this study was to test the hypothesis that cardiovascular disease occurs to the greatest extent in persons with prediabetes mellitus who are also insulin resistant. In 2003, 664 non-diabetic women (n = 457) and men (n = 207), aged 52 ± 16 and 53 ± 15 years, were surveyed during a programme for cardiovascular disease prevention. Fasting plasma glucose concentrations defined participants as having normal fasting plasma glucose (fasting plasma glucose <5.6 mmol/L) or prediabetes mellitus (fasting plasma glucose ⩾ 5.6 and <7.0 mmol/L). The tertile of prediabetes mellitus subjects with the highest fasting plasma insulin concentration was classified as insulin resistant. Baseline cardiovascular disease risk factors were accentuated in prediabetes mellitus versus normal fasting glucose, particularly in prediabetes mellitus/insulin resistant. In 2012, 86% of the sample were surveyed again, and the crude incidence for cardiovascular disease was higher in subjects with prediabetes mellitus versus normal fasting glucose (13.7 vs 6.0/100 persons/10 years; age- and sex-adjusted hazard ratio = 1.88, p = 0.052). In prediabetes mellitus, the crude incidences were 22.9 versus 9.6/100 persons/10 years in insulin resistant versus non-insulin resistant persons (age- and sex-adjusted hazard ratio = 2.36, p = 0.040). In conclusion, cardiovascular disease risk was accentuated in prediabetes mellitus/insulin resistant individuals, with a relative risk approximately twice as high compared to prediabetes mellitus/non-insulin resistant subjects.

RESUMEN

Thrombocytopenic thrombotic purpura (TTP) is a thrombotic microangiopathy associated with hematopoietic stem cells transplantation, pregnancy, puerperium, drugs, bloody diarrhea, a heterogeneous group of illnesses, such as malignant hypertension, autoimmune and neoplastic diseases, infections, and an idiopathic group that includes the pathologies that don't apply for the preceding clinical categories. Tuberculosis is an illness of intermediate incidence in Argentina, with increased frequency in high-risk groups. In this article, we present the case of a 60 years old male patient, with abdominal pain, cough and nocturnal sweating. He was diagnosed as having thrombocytopenia, and a few days later, microangiopathic anemia and TTP. Further examinations led TBC diagnosis based on: 1) acid fast bacillus (+++) for Ziehl Neelsen stain in bronco alveolar lavage, 2) laryngeal lesion and 3) ileocecal valve lesion. We report this case, because TBC has rarely been associated with TTP in medical literature.

RESUMEN

La púrpura trombótica trombocitopénica (PTT) es una microangiopatía trombótica asociada a cuadros de trasplante de células madre hematopoyéticas, embarazo y posparto, al uso de ciertas drogas, diarrea sanguinolenta, a un grupo heterogéneo de trastornos como enfermedades autoinmunes, hipertensión maligna, enfermedades neoplásicas, diversas infecciones y un grupo llamado idiopático, donde se incluyen aquellos en quienes no se cumplieron los criterios de las categorías clínicas anteriores. La tuberculosis (TBC) es una enfermedad de incidencia intermedia en Argentina, más frecuente en determinados grupos poblacionales. Presentamos el caso de un varón de 60 años que consulta por dolor abdominal, tos y sudoración nocturna; se detectó primero trombocitopenia y luego de algunos días anemia microangiopática, lo que llevó al diagnóstico de PTT. Posteriormente, al continuar con la evaluación, se diagnosticó TBC por: 1) baciloscopia positiva para bacilos ácido-alcohol resistentes (+++) por técnica de Ziehl Neelsen en lavado broncoalveolar, 2) lesiones en laringe y 3) lesiones en válvula ileocecal. La TBC ha sido pocas veces asociada con la PTT en la literatura, razón por la cual presentamos este caso.

RESUMEN

This analysis evaluated the hypothesis that the plasma triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) concentration ratio can help identify patients with essential hypertension who are insulin-resistant, with the cardiovascular disease (CVD) risk profile associated with that defect. Data from a community-based study developed between 2003 and 2012 were used to compare CVD risk factors and outcome. Plasma TG/HDL-C cut-points of 2.5 (women) and 3.5 (men) subdivided normotensive (n = 574) and hypertensive (n = 373) subjects into "high" and "low" risk groups. Metabolic syndrome criteria (MetS) were also used to identify "high" and "low" risk groups. The baseline cardio-metabolic profile was significantly more adverse in 2003 in "high" risk subgroups, irrespective of BP classification or definition of risk (TG/HDL-C ratio vs. MetS criteria). Crude incidence of combined CVD events increased across risk groups, ranging from 1.9 in normotensive-low TG/HDL-C subjects to 19.9 in hypertensive-high TG/HDL-C ratio individuals (P for trends <.001). Adjusted hazard ratios for CVD events also increased with both hypertension and TG/HDL-C. Comparable findings were seen when CVD outcome was predicted by MetS criteria. The TG/HDL-C concentration ratio and the MetS criteria identify to a comparable degree hypertensive subjects who are at greatest cardio-metabolic risk and develop significantly more CVD.

RESUMEN

Sjögren's syndrome is an autoimmune disease characterized by decreased exocrine gland secretions; patients may also present several hematological abnormalities, like lymphopenia. We describe the case of a 28 year old man who complained of headache a month of duration, with fever and vomiting in the last 48 hours. He also presented skin lesions on trunk and face, without neck stiffness. The diagnosis of duration infection was confirmed by culture from the skin biopsy and spinal fluid specimens; in addition, the presence of lymphopenia, positive anti Ro-SSA antibodies, poor concentration of the tracer in scintigraphy and lymphocytic infiltration in salivary glands confirmed the diagnosis of Sjögren's syndrome. the patient was successfully treated with liposomal amphotericin and itraconazole. We report this case to emphasize that opportunistic infections, such as disseminated histoplasmosis, may be an uncommon clinical presentation of Sjögren's syndrome.

RESUMEN

El síndrome de Sjögren es una enfermedad autoinmune caracterizada por disminución de las secreciones de las glándulas exocrinas; puede presentar también diversas alteraciones hemáticas, entre ellas linfopenia.

Sjögren's syndrome is an autoimmune disease characterized by decreased exocrine gland secretions; patients may also present several hematological abnormalities, like lymphopenia. We describe the case of a 28 year old man who complained of headache a month of duration, with fever and vomiting in the last 48 hours. He also presented skin lesions on trunk and face, without neck stiffness. The diagnosis of duration infection was confirmed by culture from the skin biopsy and spinal fluid specimens; in addition, the presence of lymphopenia, positive anti Ro-SSA antibodies, poor concentration of the tracer in scintigraphy and lymphocytic infiltration in salivary glands confirmed the diagnosis of Sjögren's syndrome. The patient was successfully treated with liposomal amphotericin and itraconazole. We report this case to emphasize that opportunistic infections, such as disseminated histoplasmosis, may be an uncommon clinical presentation of Sjögren's syndrome.

RESUMEN

El síndrome de Sj÷gren es una enfermedad autoinmune caracterizada por disminución de las secreciones de las glándulas exocrinas; puede presentar también diversas alteraciones hemáticas, entre ellas linfopenia. Presentamos el caso de un varón de 28 años que consultó por cefalea de un mes de evolución a la que se agregaron en las últimas 48 horas vómitos y fiebre. Presentaba lesiones en piel de tronco y cara; no tenía rigidez de nuca. Se demostró infección por Histoplasma capsulatum var. capsulatum en piel y líquido cefalorraquídeo, linfopenia, anticuerpos anti Ro-SSA positivos, baja concentración del trazador en centellograma de glándulas salivales e infiltración linfocitaria en glándulas salivales, lo que permitió confirmar al diagnóstico de síndrome de Sj÷gren. El tratamiento con anfotericina liposomal e itraconazol mejoró el cuadro clínico. Comunicamos este caso para referir que una infección oportunista, como la histoplasmosis diseminada, puede ser una forma poco común de presentación del síndrome de Sj÷gren.(AU)
