Lipid Horizons: Recent Advances and Future Prospects in LBDDS for Oral Administration of Antihypertensive Agents

The lipid-based drug delivery system (LBDDS) is a well-established technique that is anticipated to bring about comprehensive transformations in the pharmaceutical field, impacting the management and administration of drugs, as well as treatment and diagnosis. Various LBDDSs verified to be an efficacious mechanism for monitoring hypertension systems are SEDDS (self-nano emulsifying drug delivery), nanoemulsion, microemulsions, vesicular systems (transferosomes and liposomes), and solid lipid nanoparticles. LBDDSs overcome the shortcomings that are associated with antihypertensive agents because around fifty percent of the antihypertensive agents experience a few drawbacks including short half-life because of hepatic first-pass metabolism, poor aqueous solubility, low permeation rate, and undesirable side effects. This review emphasizes antihypertensive agents that were encapsulated into the lipid carrier to improve their poor oral bioavailability. Incorporating cutting-edge technologies such as nanotechnology and targeted drug delivery, LBDDS holds promise in addressing the multifactorial nature of hypertension. By fine-tuning drug release profiles and enhancing drug uptake at specific sites, LBDDS can potentially target renin-angiotensin-aldosterone system components, sympathetic nervous system pathways, and endothelial dysfunction, all of which play crucial roles in hypertension pathophysiology. The future of hypertension management using LBDDS is promising, with ongoing reviews focusing on precision medicine approaches, improved biocompatibility, and reduced toxicity. As we delve deeper into understanding the intricate mechanisms underlying hypertension, LBDDS offers a pathway to develop next-generation antihypertensive therapies that are safer, more effective, and tailored to individual patient needs.

High- and low-dose cyclophosphamide in Egyptian lupus nephritis patients: a multicenter retrospective analysis

BACKGROUND

Lupus nephritis (LN) is a common serious presentation of systemic lupus erythematosus. Cyclophosphamide (CYC) and mycophenolate mofetil (MMF) are listed as the first-line drugs in induction therapy for LN.

OBJECTIVE

This study aimed to compare high- and low-dose CYC in a cohort of Egyptian LN patients.

PATIENTS AND METHODS

The data of 547 patients with class III/IV active LN who received CYC as induction therapy were retrospectively analyzed. Whereas 399 patients received 6‑monthly 0.5-1 g/m2 CYC doses, 148 patients received six biweekly 500 mg CYC doses. Demographic data, laboratory test results, and disease activity index were recorded and compared at presentation and at 6, 12, 18, 24, and 48 months of follow-up.

RESULTS

After 48 months, the proportion of patients maintaining normal creatinine levels was higher in the group receiving induction therapy with high-dose CYC (67.9%, 60.4%, p = 0.029), and these patients also had higher proteinuria remission at 36 (26.6%, 14.8%, p = 0.014) and 48 months (24.3%, 12.8%, p = 0.006). Comparison of patient outcomes according to both induction and maintenance therapy showed the best results in patients who received high-dose CYC and continued MMF as maintenance therapy.

CONCLUSION

High- and low-dose CYC are comparable in early phases of treatment. However, after a longer duration of follow-up, high-dose CYC was associated with higher remission rates in the current cohort.

The effect of health literacy intervention on adherence to medication of uncontrolled hypertensive patients using the M-health

BACKGROUND

Given that patients' medication adherence is regarded as the major part of disease control and improving health literacy can be effective in promoting adherence to healthy behaviors, the present study aimed to investigate the effect of health literacy intervention based on the medication adherence among uncontrolled hypertensive patients using mobile health (M-health).

METHODS

An interventional study with a quasi-experimental design, was conducted on 118 uncontrolled hypertensive patients. Participants were randomly divided into the intervention (n = 59) and control (n = 59) groups using blocked randomization. In the intervention group, a mobile health (M-health) program was designed using programmed instruction to improve patients' health literacy over a period of 3 months. Data was collected by administering health literacy and medication adherence questionnaires to participants before and after the intervention. The analysis involved using the independent sample t-test to compare the variables before and after the study.

RESULTS

Before the intervention, the total score of health literacy was 33.34 and 33.14 in the intervention and control groups, respectively. After the intervention, it increased to 40.36 and 34.20 in the intervention and control groups, respectively, which was statistically significant in the intervention group (p = 0.01). Moreover, the medication adherence score of the intervention group significantly increased after the intervention. Both systolic and diastolic blood pressure decreased in the intervention group. However, it should be noted that the decrease in systolic blood pressure by 148.98 was statistically significant, while the decrease observed in diastolic blood pressure in the intervention group was not statistically significant (p = 0.08).

CONCLUSION

The application of programmed instruction through M-Health has shown a positive effect on the health literacy of uncontrolled hypertensive patients. In addition to detecting and treating patients, it is important to prioritize the improvement of health literacy in terms of medication adherence and the adoption of healthy behaviors.

Evaluation of Psychological Distress, Self-Care, and Medication Adherence in Association with Hypertension Control

Background. Most of the patients with hypertension (HTN) who undergo medical therapy unaccompanied by psychological and behavioral interventions may not achieve their goal in HTN treatment. Self-care is a key factor in controlling HTN. Given that depression, stress, and anxiety are the most psychological disorders in chronic illnesses. Their impact on self-care, quality of life, and HTN control must be studied more. Methods. We analyzed the difference in medication adherence in 252 patients with low vs. high psychological distress. Also, patients with controlled and uncontrolled HTN were compared according to their psychological distress scores. We further assessed the relation of psychological distress, self-care, and medication adherence with patients’ demographic characteristics. Results. 61.3% of our participants were female with a mean age of 60.6 ± 11.35 and male participants had a mean age of 60.5 ± 11.55. The psychological distress score was significantly higher in women with uncontrolled HTN ( $p$ value = 0.044). Also, individuals with controlled HTN tend to have a higher medication adherence score ( $p$ value = 0.01) and higher self-care score ( $p$ value = 0.033). Hypertensive females had a higher psychological distress score (3.35 ± 2.05) and a lower self-care score (64.05 ± 8.16). There was a positive relationship between age and drug adherence. The self-care score was higher (65.95 ± 7.88) in patients having lower psychological distress levels. Conclusion. A lower psychological distress score can result in better self-care, enhancing the probability of better HTN control; thus, psychological interventions may be necessary for the treatment of HTN. However, more studies are needed to assess the effectiveness of this intervention.

Barriers to up-titrated antihypertensive strategies in 12 sub-Saharan African countries: the Multination Evaluation of hypertension in Sub-Saharan Africa Study

BACKGROUND

Sub-Saharan Africa (SSA) faces the highest rate of hypertension worldwide. The high burden of elevated blood pressure (BP) in black people has been emphasized. Guidelines recommend two or more antihypertensive medications to achieve a BP control. We aimed to identify factors associated with prescription of up-titrated antihypertensive strategies in Africa.

METHODS

We conducted a cross-sectional study on outpatient consultations for hypertension across 12 SSA countries. Collected data included socioeconomic status, antihypertensive drugs classes, BP measures, cardiovascular risk factors and complication of hypertension. We used ordinal logistic regression to assess factors associated with prescription of up-titrated strategies.

RESULTS

The study involved 2123 treated patients with hypertension. Patients received monotherapy in 36.3 vs. 25.9%, two-drug in 42.2 vs. 45% and three and more drugs strategies in 21.5 vs. 29.1% in low (LIC) and middle (MIC) income countries, respectively. Patients with sedentary lifestyle [OR 1.4 (1.11-1.77)], complication of hypertension [OR 2.4 (1.89-3.03)], former hypertension [OR 3.12 (2.3-4.26)], good adherence [OR 1.98 (1.47-2.66)], from MIC [OR 1.38 (1.10-1.74)] and living in urban areas [OR 1.52 (1.16-1.99)] were more likely to be treated with up-titrated strategies. Stratified analysis shows that in LIC, up-titrated strategies were less frequent in rural than in urban patients (P for trend <0.01) whereas such difference was not observed in MIC.

CONCLUSION

In this African setting, in addition to expected factors, up-titrated drug strategies were associated with country-level income, patient location and finally, the interplay between both in LIC. These results highlight the importance of developing policies that seek to make multiple drug classes accessible particularly in rural and LIC.

Evaluating the efficacy of telephone-based outreach in addressing hypertension control among black men with severe hypertension: An observational study

BACKGROUND

The high prevalence of uncontrolled hypertension (systolic blood pressure [SBP] ≥140 mmHg or diastolic blood pressure [DBP] ≥90 mmHg) in Black patients represents a significant racial health disparity in the United States.

AIMS

This study evaluated the efficacy of a telephone-based strategy for inviting high-risk patients with severe hypertension to weekly self-management education classes. Further, the study assessed how the outreach intervention correlated with relevant quality improvement outcomes, including improved blood pressure and primary care follow-up among our clinic population of Black men with severe hypertension.

METHODS

A cohort of 265 Black men aged ≥18 years with SBP ≥160 mmHg or DBP ≥100 mmHg at the most recent clinic visit were identified using Epic reports formatted for Federal Uniformed Data Set annual reporting. Telephone outreach was used to invite the cohort to attend weekly in-person classes facilitated by various healthcare professionals. Logistic regression was performed to determine the associations between being reached by phone with (1) class attendance and (2) follow-up appointment attendance.

RESULTS

Most of the Black men were single (57.4%, n = 152), 49.1% had history of alcohol or substance use (n = 130), and 35.8% (n = 95) was uninsured. The average age was 55.6 years (SD = 11.6). After controlling for sociodemographic factors, being reached by phone was significantly associated with an increased likelihood of patient attendance at follow-up appointments (OR = 1.91, p = .038) but not with class attendance (OR = 2.45, p = .155). Patients who attended a follow-up appointment experienced significant reductions in both SBP and DBP at 9 months.

LINKING EVIDENCE TO ACTION

Telephone outreach was labor-intensive but effective in keeping under-resourced patient populations engaged in primary care. Future work should aim to develop more efficient strategies for engaging high-risk patients in self-monitoring education to manage hypertension.

Measurement of the Surface Area of the Renal Sinus Fat Using MDCT: Correlation with Presence and Severity of Essential Hypertension and Body Mass Index

Objectives:

Essential hypertension remains a major modifiable risk factor for cardiovascular disease. Excess visceral adipose tissue is associated with the presence of adverse metabolic risk factors. Our study aims to measure the surface area of the renal sinus fat using MDCT and correlate the renal sinus surface area with the presence and grading of essential hypertension as well as body mass index.

Materials and Methods:

This cross-sectional study included two groups; the patients’ group including 40 cases presented with a history of primary essential hypertension and the control group including 40 cases. The average of the surface area of the two kidneys as well as the average of the surface area of sinus fat was measured in the control and patient subgroups and was correlated with the presence and grading of essential hypertension as well as body mass index.

Results:

There was a significant correlation between the presence and grading of essential hypertension with prominent renal sinus fat. There was a significant correlation between the average surface area of kidneys and surface area of sinus fat in overweight and obese groups than in the control group (P < 0.01).

Conclusion:

Obesity is now recognized as a risk factor for the development of renal dysfunction. There was a significant correlation between the surface area of renal sinus fat measured using MDCT and the presence as well as grading of essential hypertension, suggesting that renal sinus fat may promote cardiovascular events.

Association of endothelial nitric oxide synthase intron 4a/b gene polymorphisms and hypertension: a systematic review and meta-analysis

OBJECTIVE

We conducted meta-analysis of relevant case-control trials to determine the association between endothelial nitric oxide synthase (eNOS) intron 4a/b gene polymorphisms and hypertension susceptibility.

METHODS

We searched the PubMed, Cochrane, and Embase databases using relevant keywords and reviewed pertinent literature sources. All articles published up to July 2019 were considered for inclusion. Based on the qualified studies, we performed a meta-analysis of the associations between eNOS intron 4a/b polymorphisms and the risk of hypertension.

RESULTS

Fourteen studies were included in this meta-analysis, including 3344 cases and 3377 controls. The eNOS intron 4a/b locus was significantly associated with increased susceptibility to hypertension (including essential hypertension) in the overall population, according to dominant, allelic, homozygote, heterozygote, and regressive models, in the mixed population according to the regressive model, and in Caucasians according to the dominant, allelic, heterozygote, and regressive models. The eNOS intron 4a/b locus was also significantly associated with increased susceptibility to essential hypertension in the mixed population according to the heterozygote model.

CONCLUSION

eNOS intron 4a/b gene polymorphisms increase susceptibility to hypertension, including essential hypertension.

Nutritional status and morbidity patterns of the elderly in a Northwestern Nigerian hospital: A cross-sectional study

Context

Nutrition is a significant factor in determining the health of older people because it affects almost all organs and systems, which could lead to varieties of diseases and premature death.

Aim

To determine the nutritional status and its association with the morbidity patterns of elderly patients.

Settings and Design

A cross-sectional hospital-based descriptive study involving 348 patients aged 60 years and above who presented at the Family Medicine Clinic.

Subjects and Methods

Data of the socio-demographic profile, anthropometric measurements and clinical diagnosis were collected. The co-morbidities were classified based on the number, duration and affected organ or system. The nutritional status was assessed with the Mini-Nutritional Assessment tool.

Statistical Analysis

Chi-square test and logistic regression analysis were used to determine associations between nutritional status and morbidity patterns of the elderly. The level of significance was set at a P ≤ 0.05.

Results

A total of 348 respondents were recruited with 60.9% of females and mean age of 67.83 (standard deviation ± 7.53) years. The prevalence of malnutrition was 25.3% and of risk of malnutrition 56.6%. Furthermore, the prevalence of multi-morbidity was 74.4%. Advanced age (odd ratio = 8.911, confidence interval [CI] = 1.992-39.872, P = 0.004), underweight (OR = 1.167, CI = 0.291-37.846, P < 0.001), lack of formal education, (OR = 1.569, CI = 0.357-0.908, P = 0.018), low monthly income (OR = 1.975, CI = 1.376-2.836, P < 0.001), chronic respiratory diseases (OR = 4.250, CI = 4.025-4.492, P < 0.001) and physical inactivity (OR = 2.466, CI = 1.063-5.722, P = 0.036) were the predictors of malnutrition. Furthermore, the duration of chronic disease for more than 10 years (OR = 1.632, CI = 0.408-0.979, P = 0.040) was significantly associated with at-risk of malnutrition.

Conclusion

The study revealed advanced age, underweight, low educational status, chronic respiratory diseases and physical inactivity as independent risk factors for malnutrition among the elderly.

ACE inhibitor induced visceral angioedema: an elusive diagnosis

ACE inhibitors are widely used and well-tolerated drugs. Angioedema is a well-known adverse effect, which involves the viscera rarely. This is a case of a 44-year-old African-American man with newly diagnosed hypertension, who presented with lower abdominal pain and diarrhoea. Based on the clinical picture and radiographic findings, lisinopril-induced intestinal angioedema was diagnosed. He recovered with supportive treatment, and the lisinopril was permanently discontinued. The mechanism of angioedema is thought to be the inhibition of ACE-mediated degradation of bradykinin, which is a peptide responsible for vasodilation and increased vascular permeability. While the external angioedema is unmistakable, intestinal angioedema has a relatively non-specific presentation and chronology, often leading to missed diagnosis and unnecessary interventions. Most common symptoms are abdominal pain and diarrhoea. Characteristic radiographic findings include ‘doughnut sign’ and ‘stacked coin’ appearance. Treatment is supportive. ACE inhibitors should be discontinued to prevent a recurrence.

Reaching the Hard-to-Reach: Outcomes of the Severe Hypertension Outreach Intervention

INTRODUCTION

Severe hypertension (≥180 mmHg systolic or ≥110 mmHg diastolic) is associated with a twofold increase in the relative risk of death. At the authors' Federally Qualified Health Center in the Southeast, 39% of adults (n=8,695) had hypertension, and 3% (n=235) were severe. The purpose of this project was to lower blood pressure and improve the proportion of patients achieving the Agency for Healthcare Research and Quality goal for blood pressure.

METHODS

This quality improvement project was performed in 2017 in three 3-month Plan, Do, Study, Act cycles using a multidisciplinary outreach model in a community-based primary care setting. A clinical team including physicians, nurses, patient navigators, behavioral health counselors, and pharmacists contacted adult patients with severe hypertension (≥180/110 mmHg), scheduled visits, and established blood pressure and medication management goals. The data review and analysis concluded in 2019.

RESULTS

Among patients with blood pressure ≥180/110 mmHg (n=235), the average age was 57 years (SD=12 years), 37% (n=87) were male, 82% (n=193) were Black, and 46% (n=108) were uninsured. The majority of those contacted attended a follow-up appointment within the 9-month project (77%, n=181) and achieved an improved systolic blood pressure (87%, n=167) and diastolic blood pressure (76%, n=146). Target blood pressure of <140/90 mmHg was achieved in 29% of patients (n=53). Medication possession ratio improved from 23% to 40% among patients reached by pharmacists (n=30). Fewer deaths occurred in those reached by the intervention than in those not reached (n=1 vs n=3).

CONCLUSIONS

Multidisciplinary outreach and use of evidence-based guidelines (Eighth Joint National Committee) were associated with lower blood pressure in patients with severe hypertension.

Using big data to promote precision oral health in the context of a learning healthcare system

There has been a call for evidence-based oral healthcare guidelines, to improve precision dentistry and oral healthcare delivery. The main challenges to this goal are the current lack of up-to-date evidence, the limited integrative analytical data sets, and the slow translations to routine care delivery. Overcoming these issues requires knowledge discovery pipelines based on big data and health analytics, intelligent integrative informatics approaches, and learning health systems. This article examines how this can be accomplished by utilizing big data. These data can be gathered from four major streams: patients, clinical data, biological data, and normative data sets. All these must then be uniformly combined for analysis and modelling and the meaningful findings can be implemented clinically. By executing data capture cycles and integrating the subsequent findings, practitioners are able to improve public oral health and care delivery.

Pharmacist impact on health outcomes in a homeless population

OBJECTIVE

The aim of this study was to analyze the effect of clinical pharmacy services on health outcomes and medication adherence concerning hypertension and diabetes in the homeless population.

METHODS

This was a retrospective quasi-experimental study conducted between January 1, 2015, and December 31, 2016. The primary outcomes included median blood pressure and median glycosylated hemoglobin (A1C) change from baseline. The secondary end points included adherence to hypertension and diabetes medication, in addition to the differences in the number of admissions to urgent care clinics, emergency departments, or hospitals pre- and postpharmacist clinic visit.

RESULTS

One-hundred ninety-eight homeless patients were seen by a pharmacist over the study time frame, and 116 of these patients were included. There was a decrease in systolic and diastolic blood pressure in the 6-months postpharmacist visit (139 mm Hg vs. 135 mm Hg, P = 0.413, and 85 mm Hg vs. 82 mm Hg, P = 0.197, respectively). The percentage of patients who met the blood pressure goals increased from 55% to 66% (P = 0.093). A statistically significant decrease in A1C was found (7.7% vs 7.2%, P = 0.038). The number of patients who met the A1C goal increased from 20% to 41% (P = 0.267) after pharmacist intervention. No medication class was associated with a median proportion of days covered of 80% or greater. However, differences were seen with biguanides (34% vs. 43%, P = 0.004), calcium channel blockers (44% vs. 59%, P < 0.001), and thiazides (28% vs. 39%, P = 0.039) pre- and postintervention. There was no difference in the number of visits to emergency departments or urgent care clinics, or hospitalizations.

CONCLUSION

Homeless patients with hypertension and type 2 diabetes who had at least 1 visit with a pharmacist showed some improved health outcomes. Statistically significant benefits were seen in diabetes management, but not for blood pressure control.

Early menarche and blood pressure in adulthood: systematic review and meta-analysis

Background

It has been reported that early menarche is associated with high blood pressure and hypertension. However, some studies have failed to observe such association. We carried out a systematic review and meta-analysis on the association of early menarche with hypertension and high blood pressure in adulthood.

Methods

PUBMED, SciELO, Scopus and LILACS databases were searched. Studies that evaluated the association of early menarche with hypertension or high blood pressure, among women aged 20 years or more were included. Random effects models were used to pool the estimates. Meta-regression was used to evaluate the contribution of different co-variables to heterogeneity.

Results

We identified 17 studies with 18 estimates on the association of early menarche with hypertension and high blood pressure. The odds of hypertension/high blood pressure was higher among women with early menarche [pooled (OR):1.25; 95% confidence interval (CI): 1.17-1.34; P < 0.001]. In the meta-regression analysis, studies evaluating 1500 subjects or more had a higher pooled OR [1.27; 95%CI (1.19;1.36)] than those with less participants. Although funnel plots showed some asymmetry, Egger tests were not statistically significant. Therefore, it is unlikely that the observed association was to publication bias.

Conclusions

Early menarche is associated with hypertension among adult woman.

Prescribing pattern of antihypertensive medication and adherence to Joint National Commission-8 guidelines in a rural tertiary care Indian teaching hospital

Background Antihypertensive medications are one among the most highly used drugs across the globe as well as in India, and their prescribing pattern will be erratic despite the various clinical guidelines. Few studies address the pattern and adherence to the standard treatment guidelines in India. This study aimed to review the prescribing pattern of antihypertensive medications in a rural tertiary care teaching Indian hospital and to investigate the adherence to the Joint National Commission-8 (JNC-8) guidelines on prevention, detection, evaluation, and treatment of hypertension in adults. Methods A prospective observational study was conducted among the participants from four different inpatient wards who are aged >18 years, without gender restriction. The prescription pattern was reviewed and adherence to the JNC-8 guidelines was also assessed. A purposive sampling technique was adopted and descriptive statistics were used in Statistical Package for the Social Sciences v16. Results Of the 101 participants included in the study, 62 (61.39%) were female, 23.76% were aged <30 and >60 years, and the other 52.48% belong to the range of 30-60 years. As per JNC-8 guidelines, 4.95%, 17.82%, 44.55%, and 32.67% of patients were classified as normal, pre-hypertensive, stage I, and stage II, respectively. Most of them (31.68%) were free from comorbidities. The most (23.76%) prescribed drug was calcium channel blocker (CCB), and 15.84% of the patients received combination therapy. Treatment was effective in 70.30% of the patients through analyzing their blood pressure even though the adherence to the JNC-8 guidelines was only in 54.46%. Conclusions Our study revealed that CCB was the most prescribed drug, and in spite of the only 50% adherence rate, treatment was effective in the majority of the population. The treatment outcome can be improved if the adherence rate is increased further.

Association between α-adducin rs4961 polymorphism and hypertension: A meta-analysis based on 40 432 subjects

BACKGROUND

Recently, the role of α-adducin rs4961 polymorphism in hypertension (HTN) was intensively analyzed, but the results of these studies were inconsistent. Therefore, we performed this study to better assess the relationship between α-adducin rs4961 polymorphism and the likelihood of HTN.

METHODS

Eligible studies were searched in PubMed, Medline, Embase, and Web of Science. Odds ratios with 95% confidence intervals were used to assess the relationship between α-adducin rs4961 polymorphism and HTN.

RESULTS

A total of 33 studies with 40 432 participants were analyzed. Significant associations with the likelihood of HTN were detected for the α-adducin rs4961 polymorphism with fixed effect models (FEM) (dominant model: P = 0.003; allele model: P = 0.003), but not with random effect models (REM). Further subgroup analysis according to ethnicity of participants revealed that the α-adducin rs4961 polymorphism was significantly associated with the likelihood of HTN in Asians (7721 cases and 8299 controls) with both FEMs (dominant model: P < 0.0001; additive model: P = 0.01; allele model: P < 0.0001) and REMs (dominant model: P = 0.0005; additive model: P = 0.03; allele model: P = 0.0006).

CONCLUSIONS

Our findings indicate that the α-adducin rs4961 polymorphism may serve as a genetic biomarker of HTN in Asians.

Renal Involvement in Antiphospholipid Syndrome

Antiphospholipid syndrome is a complex autoimmune disease, characterized by the presence of vascular thrombosis, obstetric, hematologic, cutaneous, and cardiac manifestations. Renal disease in patients with antiphospholipid syndrome was not recognized in the first descriptions of the disease, but later on, the renal manifestations of the syndrome have been investigated widely. Renal manifestations of antiphospholipid syndrome conform a wide spectrum of diverse renal syndromes. Hypertension is one of the most frequent, but less commonly recognized renal alteration. It can be difficult to control as its origin is renovascular. Renal vascular thrombosis can be arterial or venous. Other alterations are renal infarction and vascular thrombosis in arterial territories. Venous thrombosis can be present in primary and secondary antiphospholipid syndrome; it presents with worsening of previous proteinuria or de novo nephrotic syndrome, hypertension and renal failure. Antiphospholipid syndrome nephropathy is a vascular disease that affects glomerular tuft, interstitial vessels, and peritubular vessels; histopathology characterizes the renal lesions as acute or chronic, the classic finding is thrombotic microangiopathy, that leads to fibrosis, tubule thyroidization, focal cortical atrophy, and glomerular sclerosis. Antiphospholipid syndrome nephropathy can also complicate patients with systemic lupus erythematosus, and there is vast information supporting the worse renal prognosis in this group of patients with the classic histopathologic lesions. Treatment consists of anticoagulation, as for other thrombotic manifestations of antiphospholipid syndrome. There is some evidence of glomerulonephritis as an isolated lesion in patients with antiphospholipid syndrome. The most frequently reported glomerulonephritis is membranous; with some reports suggesting that immunosuppressive treatment may be effective. Patients with end stage renal disease commonly are positive for antiphospholipid antibodies, but it is not clear what is the role of aPL in this setting. Patients with vascular access may have complications in the presence of antibodies so that anticoagulation is recommended. Patients ongoing renal transplant with persistent antiphospholipid antibody positivity may have early and late graft failure.

Prevalence and Gender-Specific Influencing Factors of Hypertension among Chinese Adults: A Cross-Sectional Survey Study in Nanchang, China

Hypertension has become the leading cause of death worldwide; data on hypertension among Nanchang adults are sparse. The aim of this study was to investigate the prevalence and gender-specific influencing factors of hypertension in adults in Nanchang, China. A cross-sectional survey was conducted with a representative sample of 2722 Chinese residents aged 18 years and above between May and September 2016, with a response rate of 92.4% (2516/2722). A stratified cluster sampling method was adopted in this study. Data on prevalence and influencing factors were obtained from a standard questionnaire and physical measurements. Univariate and multivariate logistic regressions were performed to analyze the influencing factors. The age-standardized prevalence was 19.8% (18.2-21.3) (male: 19.5% (18.0-21.1); female, 20.01% (18.5-21.6)). Factors positively associated with hypertension prevalence were past smoking, diabetes mellitus (DM), and overweight and obesity in both genders. Abdominal obesity and family history of cardiovascular diseases (CVD) were risk factors only in males; sleeping time and consumption of fresh vegetables and fruits were related to the prevalence of hypertension only in females. These findings will form the baseline information for the development of more effective approaches to enhance current prevention and control management of hypertension.

Nephrolithiasis and risk of hypertension: a meta-analysis of observational studies

Background

Observational studies have demonstrated an association between nephrolithiasis and hypertension. The aim of this meta-analysis was to summarize all available evidence.

Methods

PubMed, EMBASE, the Cochrane Central Register of Controlled Trials databases, and the reference lists of relevant articles were searched to identify observational studies that reported study-specific risk estimates comparing the risk of hypertension in patients with nephrolithiasis. We used a random-effect model to pool the study-specific risk estimates. We also assessed the potential heterogeneity by subgroup analyses, meta-regression analyses, and sensitivity analyses.

Results

A total of 7 articles including 9 studies (n = 313,222 participants) were eventually identified in this meta-analysis. In comparison with the patients who did not have nephrolithiasis, nephrolithiasis significantly increased the risk of hypertension (OR, 1.43; 95% CI, 1.30–1.56), with significant heterogeneity between these studies (I² = 83.5%, P <0.001). The heterogeneity reduced in subgroups of cohort studies, USA, large sample size trials, men, and adjustment for confounding factors ≥ 5. Sensitivity analysis further demonstrated the results to be robust.

Conclusions

Nephrolithiasis is associated with increased risk of hypertension. Future randomized, high-quality clinical trials are encouraged to definitively clarify the relationship between nephrolithiasis and hypertension, which may influence clinical management and primary prevention of hypertension in nephrolithiasis patients.

Outcomes of acute kidney injury in a department of internal medicine in ABIDJAN (cote D'IVOIRE)

AIM

To investigate the prognostic factors of acute kidney injury (AKI) in our daily practice.

METHODS

We analyzed the cohort of patients hospitalized for AKI in the period from January 2010 to December 2015 in the Department of Internal Medicine, University Hospital of Treichville. Kaplan-Meier curves were built for survival analysis. Cox regression analysis was used to identify independent predictors of mortality.

RESULTS

We collected 414 cases of AKI during the study period. The mean age was 48.3 ± 16.8 years. We observed a male predominance with a sex ratio (236/178) of 1.32. In multivariate analysis, the predictive factors of death were age ≥ 65 years (HR = 2.13; 95% CI = 1.28-3.55; P = 0.004), AKI stage 3 (HR = 1.69; 95%CI = 1.13-2.50; P = 0.009), haemoglobin <8 g/dL (HR = 2.91; 95% CI = 1.79-4.72; P = 0.0001), infection (HR = 1.85; 95% CI = 1.21-2.83; P = 0.004) and drug-induced AKI (HR = 3.23; 95% CI = 1.65-6.29; P = 0.001). Factors associated with incomplete recovery or non-recovery of renal function beyond 3 months were age ≥ 65 years (OR = 4.76; 95% CI = 1.85-12.50;P = 0.001), hypertension (OR = 2.17; 95% CI = 1.07-4.34; P = 0.03), haemoglobin <8 g/dL (OR = 6.66; 95% CI = 2.94-8.28; P < 0.001), AKI stage 3 (OR = 9.09; 95% CI = 4.54-16.66; P < 0.001) malignant hypertension (OR = 5; 95% CI = 1.67-7.27; P = 0.005) and cancer (OR = 4.69; 95% CI = 2.22-6.63; P = 0.001).

CONCLUSION

The aetiologies are dominated by infections. The fatality rate is high and its risk factors are advanced age, low haemoglobin level, severe AKI, infection and drug intake. Prevention is essential.
