Effects of citalopram on blood pressure control in depressive patients with hypertension: A randomized clinical trial

Introduction

Since there is a bi-directional interaction between hypertension and depression, we aimed to evaluate the effects of citalopram administration in the management of hypertension.

Methods

A randomized clinical trial was conducted on 72 patients with concomitant depression and hypertension. The intervention group (n=41) received citalopram 20 mg daily plus anti-hypertensive standard treatment, while the control group (n=31) received only the standard treatment. The study's primary endpoint was in-office blood pressure (BP) measurement at baseline and home BP monitoring in the first and second months after entering the study.

Results

There were no significant differences in baseline systolic BP (163.3±19.6 vs.164.2±20.3 mm Hg; P=0.910) and diastolic BP (94.5±13.8 vs. 88.2±14.4; P=0.071). After one month, diastolic BP (82.7±11.7 vs. 77.09±12.2; P=0.023) was significantly higher in the control group compared to the intervention group. Two months after the intervention, systolic BP (133.8±16.5 vs. 124.5±12.4; P=0.009) and diastolic BP (80.7±10.3 vs. 73.7±9.7; P=0.002) were significantly decreased in the intervention group compared to the control group.

Conclusion

This study supported the beneficial effects of citalopram in lowering BP in patients with concomitant depression and hypertension.

New-onset systemic lupus erythematosus after BBIBP-CorV vaccination

While reports of new-onset systemic lupus erythematosus (SLE) after mRNA-based COVID-19 vaccines exist, no such reports have been documented following inactivated vaccines. We describe a case of SLE after receiving the BBIBP-CorV vaccine. The patient exhibited characteristic SLE criteria, indicating a possible association between the inactivated vaccine and new-onset SLE.

Effects of Triamterene in Hospitalized Patients with Heart Failure and Diuretic Resistance: A Randomized Clinical Trial

Due to the potential benefits of triamterene in diuretic resistance, this study was performed to assess whether triamterene add-on to the standard treatment of heart failure (HF)-related diuretic resistance improves outcomes. A randomized clinical trial was performed on 45 hospitalized patients with HF with reduced ejection fraction who had diuretic resistance. Patients were randomized to receive either triamterene 50 mg plus hydrochlorothiazide 25 mg (n = 23) or hydrochlorothiazide 50 mg alone (n = 22) until hospital discharge. The primary outcomes were changes in weight and fluid input-to-output ratio. Secondary outcomes were respiratory rate, hospitalization duration, serum sodium and potassium, estimated glomerular filtration rate, creatinine, and blood urea nitrogen levels during the study period. The mean (standard deviation) of weight changes was not significantly different in the intervention and the control groups (-6.3 [4.8] vs -4.8 [2.4] kg, respectively; P = .1). No significant differences were shown in input-to-output changes between the 2 groups (208.0 [243.4] in the intervention and 600.2 [250.3] in the control group; P = .4). Although the respiratory rate of triamterene-treated patients decreased, the difference did not reach statistical significance (P = .2). Other secondary outcomes were also similar in both groups. This study did not support the use of triamterene as an add-on therapy for patients with HF-related diuretic resistance.

Effects of Allopurinol in the Prevention of Periprocedural Myocardial Injury Following Elective Percutaneous Coronary Intervention: A Randomized Clinical Trial

Background: Periprocedural myocardial injury (PMI) after percutaneous coronary intervention (PCI) is a substantial health issue with a high mortality rate. Inflammation and oxidative stress are major contributing factors to PMI. Allopurinol inhibits xanthine oxidase (XO)-induced oxidative stress and has potential cardiovascular benefits. Methods: This randomized clinical trial evaluated 110 patients admitted to elective PCI. Patients were assigned to receive either a 1200 mg loading dose of allopurinol 2 hours before the procedure (n = 55) or the standard pretreatment (n = 55). The creatine kinase-MB (CK-MB) and cardiac troponin I (cTnI) levels were measured in both groups at the baseline, 8, and 24 hours after PCI. Results: There were no significant differences in the CK-MB levels at baseline (P = 0.71), 8 (P = 0.26), and 24 hours (P = 0.88) after PCI between the two groups. No significant changes in the cTnI levels at baseline (P = 0.26), 8 (P = 0.80), and 24 hours (P = 0.89) after the PCI were also noted. The mean difference for CK-MB and cTnI changes was not different between the two groups. Conclusion: Our study revealed that allopurinol did not reduce cardiac-specific enzymes. Further studies are required to evaluate the impact of allopurinol on preventing PCI-related myocardial injury.

Correlation between Serum Uric Acid and Non-Alcoholic Fatty Liver Disease: A Cross-Sectional Study

Background: Non-alcoholic fatty liver disease (NAFLD) is one of the important health issues with high prevalence worldwide. However, there is no approved medication for that. As one of the indicators of metabolic syndrome, uric acid might play a role in the pathogenesis of NAFLD. In this study, we aimed to determine the correlation between serum uric acid level, liver enzymes, and ultrasonographic grading of NAFLD. Methods: This cross-sectional study included patients aged 18-65 with NAFLD. Patients with other metabolic disorders and a history of using alcohol or medications that alter uric acid levels were excluded. The patients' serum uric acid, alanine aminotransferase (ALT), aspartate aminotransferase (AST) levels, and ultrasonographic grading of NAFLD at baseline, third month, and sixth month were collected. Results:  Of the 3000 patients, 500 patients met the eligibility criteria. The results showed that there is a significant positive relationship between ALT and serum uric acid level at the first (P= 0.01), third (P=0.01), and sixth month (P=0.01). Furthermore, there was a significant positive correlation between AST and serum uric acid level at the sixth month (P= 0.001). The comparison of 249 patients' ultrasonographic grading showed no significant correlation with serum uric acid levels. Conclusion: To conclude, the serum uric acid level significantly correlates with ALT and AST over six months but not with the ultrasonographic grading. Further studies are required to determine the role of uric acid-lowering agents in the treatment of NAFLD.

Monkeypox treatment: Current evidence and future perspectives

As of September 11, 2022, 57 669 reports of monkeypox infection raised global concern. Previous vaccinia virus vaccination can protect from monkeypox. However, after smallpox eradication, immunization against that was stopped. Indeed, therapeutic options following the disease onset are of great value. This study aimed to review the available evidence on virology and treatment approaches for monkeypox and provide guidance for patient care and future studies. Since no randomized clinical trials were ever performed, we reviewed monkeypox animal model studies and clinical trials on the safety and pharmacokinetics of available medications. Brincidofovir and tecovirimat were the most studied medications that got approval for smallpox treatment according to the Animal Rule. Due to the conserved virology among Orthopoxviruses, available medications might also be effective against monkeypox. However, tecovirimat has the strongest evidence to be effective and safe for monkeypox treatment, and if there is a choice between the two drugs, tecovirimat has shown more promise so far. The risk of resistance should be considered in patients who failed to respond to tecovirimat. Hence, the target-based design of novel antivirals will enhance the availability and spectrum of effective anti-Orthopoxvirus agents.

Current evidence on the use of anakinra in COVID-19

Despite the progressing knowledge in COVID-19 management, remdesivir is the only agent that got approval to inhibit viral replication. However, there are limited data about effective immunomodulatory agents to prevent cytokine release in COVID-19. Cytokine release syndrome in COVID-19 resembles secondary hemophagocytic lymphohistiocytosis, in which interleukin-1 (IL-1) plays a key role. Anakinra is the first recombinant IL-1 receptor antagonist studied for off-label use in COVID-19 treatment. This study reviews the current clinical evidence on the role of interleukin-1 in COVID-19-related cytokine storm, therapeutic effects, significant clinical concerns, and pros and cons of anakinra administration in the management of COVID-19 patients. In this review, four items are shown to be important for achieving the optimal therapeutic effects of anakinra in COVID-19 patients. These items include duration of treatment ≥ 10 days, doses ≥ 100 mg, intravenous administration, and early initiation of therapy. Also, anakinra might be more beneficial in the early stages of the disease when higher levels of cytokines are yet to be observed, which could prevent progression to severe illness and mechanical ventilation. Further studies are required to address the SARS-CoV-2 induced cytokine release syndrome and the role of anakinra in identifying ideal treatment approaches for COVID-19 patients based on their clinical status.

Comprehensive review on molnupiravir in COVID-19: a novel promising antiviral to combat the pandemic

Despite the progress in the management of COVID-19, effective oral antiviral agents are still lacking. In the present review, the potential beneficial effects of molnupiravir in the management of COVID-19 are discussed. A literature search in Google Scholar, Scopus, PubMed and clinicaltrials.gov for the relevant articles regarding the pharmacokinetics, pharmacodynamics and clinical trials of molnupiravir in the management of COVID-19 is conducted. Most of the preclinical studies and available clinical trials showed a favorable short-term safety profile of molnupiravir; however, given its possible genotoxic effects, further trials are required to confirm the long-term efficacy and safety of molnupiravir in patients with COVID-19.

Investigational antiviral drugs for the treatment of COVID-19 patients

In the current pandemic of coronavirus disease 2019 (COVID-19), antiviral drugs are at the center of attention because of their critical role against severe acute respiratory disease syndrome coronavirus 2 (SARS-CoV-2). In addition to designing new antivirals against SARS-COV-2, a drug repurposing strategy is a practical approach for treating COVID-19. A brief insight about antivirals would help clinicians to choose the best medication for the treatment of COVID-19. In this review, we discuss both novel and repurposed investigational antivirals, focusing on in vitro, in vivo, and clinical trial studies.

Potential pharmacologic treatments for COVID-19 smell and taste loss: A comprehensive review

The acute loss of taste and smell following COVID-19 are hallmark symptoms that affect 20-85% of patients. However, the pathophysiology and potential treatments of COVID-19 smell and taste loss are not fully understood. We searched the literature to review the potential pathologic pathways and treatment options for COVID-19 smell and taste loss. The interaction of novel coronavirus with ACE-2 receptors expressed on sustentacular cells and taste buds results in direct damage to the olfactory and gustatory systems. Also, the invasion of the virus to the olfactory neurons and consequent local inflammation are other proposed mechanisms. Therefore, COVID-19 patients with smell or taste loss may benefit from neuroprotective, anti-inflammatory, or depolarizing agents. Based on the current evidence, phosphodiesterase inhibitors, insulin, and corticosteroids can be promising for the management of COVID-19 smell and taste loss. This review provided crucial information for treating COVID-19-related smell and/or taste loss, urging to perform large clinical trials to find optimum treatment options.

Potential COVID-19 Therapeutic Agents and Vaccines: An Evidence-Based Review

Since the early days of 2020, the severe acute respiratory syndrome coronavirus 2 pandemic has become a global health concern. Currently, some therapies and vaccines have received US Food and Drug Administration approval or emergency use authorization for the management of coronavirus disease 2019. According to the pathophysiology of the disease, several medications have been evaluated in different clinical conditions of the disease. Evidence-based reviewing and categorizing these medications can guide the clinicians to select the proper medications according to each patient's condition. Therefore, we performed this review to categorize the coronavirus disease 2019 potential therapeutics and vaccines.

A Comprehensive Review of Tocilizumab in COVID-19 Acute Respiratory Distress Syndrome

Currently, the world is facing the pandemic of a novel strain of beta‐coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Acute respiratory distress syndrome (ARDS) is the most devastating complication of SARS‐CoV‐2. It was indicated that cytokine‐release syndrome and dominantly interleukin (IL)‐6 play a central role in the pathophysiology of ARDS related to the novel 2019 coronavirus disease (COVID‐19). Despite the global emergency of the disease, at this time, there are no proven therapies for the management of the disease. Tocilizumab is a potential recombinant monoclonal antibody against IL‐6 and currently is under investigation for the management of ARDS in patients with COVID‐19. Given these points, we reviewed the current evidence regarding the potential therapeutic role of tocilizumab and its important clinical issues in the treatment of ARDS related to COVID‐19.

Effects of Adding Pentoxifylline to Captopril on Primary Hypertension: A Pilot Randomized Clinical Trial

Because of the key role blood viscosity plays in the regulation of blood pressure (BP) and the hemorheological effects of pentoxifylline (PTX), this study was conducted to evaluate whether PTX can reduce BP when added to captopril in patients with stage 1 hypertension. In this randomized clinical trial 62 patients with stage 1 hypertension were entered. The intervention group (n = 30) received 1200 mg PTX in 3 divided doses plus 25 mg captopril 3 times a day, whereas the control group (n = 32) received only 75 mg captopril in 3 divided doses. Measurements of BP were done at baseline and in the first and second months after entering the study. Major adverse cardiac events during this period were recorded. When the systolic BP levels in the intervention and the control groups were compared, no significant differences at baseline (150.4 ± 6.03 versus 150.4 ± 6.2, P = .98) or first (138.4 ± 9.4 versus 142.3 ± 5.6, P = .08) or second (134.6  ± 8.9 versus 137.4 ± 6.0, P = .20) month of the study were noted. Similarly no significant difference was observed in the diastolic BP at baseline (91.7 ± 3.9 versus 92.0 ± 3.7, P = .84) or first (85.5 ± 5.1 versus 86.9  ± 3.8, P = .27) or second (82.6  ± 5.7 versus 84.0  ± 3.5, P = .31) month. Based on the results of present study, adding PTX as a hemorheological agent to captopril could not significantly reduce blood pressure in the patients with stage 1 hypertension.
