Blame it on the Drug: A Rare Case of Recurrent Doxycycline-Induced Pancreatitis

Wed, 2022-10-19 06:00

Cureus. 2022 Sep 14;14(9):e29171. doi: 10.7759/cureus.29171. eCollection 2022 Sep.

ABSTRACT

Doxycycline is a broad-spectrum bacteriostatic antibiotic that belongs to the tetracycline class. It is a relatively safe medication with reported side effects being gastrointestinal symptoms, bone and teeth discoloration, photosensitivity, and renal toxicity. Acute pancreatitis (AP) is an uncommon adverse effect with only a few reported cases in the literature. Despite tetracyclines being labeled as a probable causative agent of drug-induced pancreatitis (DIP), doxycycline has been rarely implicated. Herein we present the case of a 65-year-old patient who developed recurrent doxycycline-induced pancreatitis after she was inadvertently started on the medication for community-acquired pneumonia. The most common causes of pancreatitis were ruled out during her hospital admission and she was subsequently diagnosed with DIP. She was successfully treated with the cessation of the offending agent and with supportive therapy. It is critical that clinicians are aware of the possible association between doxycycline and pancreatitis to further aid in the prompt diagnosis and treatment of this condition.

Essential Oils Can Mitigate Adverse Effects of Prolonged Masking in the Hospital Setting

Tue, 2022-10-18 06:00

Holist Nurs Pract. 2022 Nov-Dec 01;36(6):344-348. doi: 10.1097/HNP.0000000000000550.

ABSTRACT

Adverse symptoms of prolonged masking were reported by personnel. A drop of essential oil was added to the mask to mitigate these effects and significantly lessened symptoms. Symptoms declined by almost half, including anxiety, nausea, and indigestion. This simple intervention can mitigate adverse effects of prolonged masking in the hospital setting.

A Retrospective Cohort Study of Multiple Immune-Related Adverse Events and Clinical Outcomes Among Patients With Cancer Receiving Immune Checkpoint Inhibitors

Tue, 2022-10-18 06:00

Cancer Control. 2022 Jan-Dec;29:10732748221130576. doi: 10.1177/10732748221130576.

ABSTRACT

BACKGROUND AND OBJECTIVES: Immune checkpoint inhibitors (ICIs) are effective in various types of cancer and cause immune-related adverse events (irAEs). The occurrence of irAEs is associated with improved survival outcome. We investigated the association between the occurrence of irAEs and overall survival (OS) and progression free survival (PFS), and the risk factors for the development of irAEs, in patients with non-small-cell lung cancer (NSCLC), gastric cancer (GC) and melanoma (MM) treated with ICIs.

METHODS: This was a retrospective observational cohort study, and the data were taken from inpatients in a hospital. OS and PFS were compared among patients with different numbers of irAEs. Log-rank test and Cox regression and logistic regression analysis were applied, and details of irAEs characteristics were summarized.

RESULTS: We obtained data from 200 patients. The major tumor types were NSCLC, GC, and MM. Median OS and PFS in all patients were 9.3 and 3.5 months, respectively. Patients without irAEs tended to have shorter OS or PFS compared with those with a single irAE or multi-system irAEs. Covariate analysis suggested that age (≥75 years), albumin (≥3.5 g/dL) and smoking history were significant for increased occurrence of irAEs. Pneumonitis and thyroiditis tended to occur frequently in patients with NSCLC and MM. The irAE grade was ≤2 in 67.3% of all irAEs, and days of irAEs onset varied.

CONCLUSION: We observed patients with irAEs tended to have better OS or PFS in patients with various types of cancers treated with ICIs. We suggest that ICIs should be used appropriately by continuously monitoring the irAEs.

Venetoclax-induced vitiligo in a patient with chronic lymphocytic leukemia

Tue, 2022-10-18 06:00

Anticancer Drugs. 2022 Nov 1;33(10):1167-1170. doi: 10.1097/CAD.0000000000001350. Epub 2022 Sep 29.

ABSTRACT

Venetoclax, a highly selective Bcl-2 inhibitor, is an orally bioavailable drug that has been approved as first-line therapy for chronic lymphocytic leukemia (CLL) in combination with obinutuzumab, as well as monotherapy in the setting of relapsed CLL. Although some of its life-threatening side effects are well known, including tumor lysis syndrome and cytopenias, others less known side effects include skin reactions. Skin rash is commonly reported in literature, which is often mild and not life-threatening. In this case report, the authors describe what is potentially the second case of venetoclax-induced vitiligo reported in literature. A 77-year-old man with CLL Rai stage II with cytogenetics showed 11 q23 deletion in 14% of cells, and 14q32 partial deletion in 9% of cells developed vitiligo in his extremities 2 years into treatment. A decision was made to continue venetoclax with close monitoring as the side effect was mild and not debilitating. The patient continued to do well. Although vitiligo is not associated with increased mortality risk, its development is associated with increased psychological stress. The mechanism by which vitiligo develops remains unclear. There may be an association between drug-induced vitiligo and improved cancer prognosis; however, larger studies need to be carried out to prove this hypothesis.

Evaluation of the effect of pharmaceutical care during inpatient treatment in a department of neurology: A retrospective study

Tue, 2022-10-18 06:00

Medicine (Baltimore). 2022 Oct 14;101(41):e30984. doi: 10.1097/MD.0000000000030984.

ABSTRACT

Common drug-related problems during neurology inpatient treatment can affect expected health results. Some interventions need to be implemented to reduce DRPs. To explore the effect of care from clinical pharmacists during inpatient treatment. Inpatients treated in the department of neurology in the Second Hospital of Shanxi Medical University between January 1 to December 31, 2019, were retrospectively included. Those who received care from the clinical pharmacist service were assigned to the pharma-care group while the other patients were assigned to the control group. From the perspective of drugs, the two groups were compared in terms of types, antimicrobial use, and key monitoring of drug use. From the perspective of patients, the two groups were compared in terms of length of stay, hospital cost, drug cost and proportion. Propensity score matching was used to balance the baseline characteristics. A total of 2684 patients were included 554 in the pharma-care group and 2130 in the control group with a median of 9 days (range, 3-30 days) hospital stay. The groups showed no significant difference in age or gender. Length of stay, the proportion of drug cost, number of adverse events, cost of antibacterial agents, use of a single antibacterial agent, and use of three or more different antibacterial agents were similar between the groups. Medicine expenses cost more in the pharma-care group. The cost and types of intensive monitoring drugs were similar, but Defined Daily Doses were lower in the control group. While clinical pharmacists may play a positive role in the pharmaceutical care of inpatients, in this study the benefits were not obvious. This may be because of the small number of clinical pharmacists in the department of neurology with narrow coverage.

Monitoring the effect of TNF-alpha inhibitors on laboratory parameters and adverse effects in different diseases: a retrospective, single-center study

Mon, 2022-10-17 06:00

Ann Saudi Med. 2022 Sep-Oct;42(5):309-318. doi: 10.5144/0256-4947.2022.309. Epub 2022 Oct 6.

ABSTRACT

BACKGROUND: The introduction of biological treatments has revolutionized the management of moderate-to-severe psoriasis. Multiple clinical trials have established the efficacy of biological agents in the treatment of moderate-to-severe psoriasis. Nevertheless, there are no clear indications for optimal monitoring intervals during treatment.

OBJECTIVES: Collect and analyze laboratory evaluation data from patients receiving biological therapy to provide a better understanding of the need for laboratory investigations before and during treatment with biological agents, and to analyze adverse events and other factors.

DESIGN: Retrospective cohort SETTINGS: Tertiary care center in Riyadh, Saudi Arabia.

PATIENTS AND METHODS: Data were collected from the electronic medical records of patients attending the dermatology, rheumatology, and gastroenterology clinics from June 2014 to June 2019. The laboratory parameters of patients who have received one of the TNF-alpha inhibitors (adalimumab, etanercept, or infliximab) were collected starting at baseline and up to at least one year from treatment initiation.

MAIN OUTCOME MEASURES: The time points at which patients developed significantly abnormal laboratory results during treatment with one of the TNF-alpha inhibitors.

SAMPLE SIZE: 250 patients RESULTS: Most patients were treated with adalimumab (38.4%); a similar proportion (38%) with infliximab, whereas only 23.6% were treated with etanercept. The majority of the significant abnormal laboratory results occurred at baseline, 3-6 and 9-12 months. Most abnormalities were among patients using infliximab, followed by etanercept, and then adalimumab. The median number of laboratory abnormalities for dermatology patients was significantly lower than that for gastroenterology patients (P<.001), and for rheumatology patients (P=.002).

CONCLUSIONS: Because dermatology patients showed a lower median number of laboratory abnormalities than patients treated by other specialties in our study, we believe that dermatology patients require less frequent laboratory monitoring. Therefore, we recommend laboratory evaluation at baseline, after 3-6 months, 1 year from the beginning of treatment, and annually thereafter for patients using TNF-alpha inhibitor agents. However, more frequent testing might be warranted according to patient comorbidities, concomitant medications, and physician judgment.

LIMITATIONS: Single center and retrospective design.

CONFLICT OF INTEREST: None.

Association between immune-related adverse events and the efficacy of PD-1 inhibitors in advanced esophageal cancer

Mon, 2022-10-17 06:00

Front Immunol. 2022 Sep 28;13:931429. doi: 10.3389/fimmu.2022.931429. eCollection 2022.

ABSTRACT

INTRODUCTION: Recent developments in immune checkpoint inhibitors (ICIs) have improved the treatment outcomes of esophageal cancer (EC); however, it may initiate immune-related adverse events (irAEs) in some patients. The ICIs' therapeutic efficacy is associated with irAEs in patients with non-small cell lung cancer or renal cell carcinoma, although this association is unknown in EC. The purpose of this study was to explore the association between irAEs and the efficacy of programmed death 1 (PD-1) inhibitors in EC patients.

PATIENTS AND METHODS: This study included patients with advanced EC treated with PD-1 inhibitors. The patients were divided into two groups according to the occurrence of irAEs. Afterward, the efficacy was compared between the irAE-negative and irAE-positive groups, and we analyzed the predictive factors of irAEs and survival.

RESULTS: Overall, 295 patients were included in this study. Baseline characteristics were balanced in the irAE-negative and irAE-positive groups. In total, 143 (48.47%) patients experienced irAEs. The most frequent irAEs were anemia (49, 16.61%), hyperthyroidism (45, 15.25%), and pneumonitis (44, 14.92%). In total, 33 (11.19%) patients had grade ≥ 3 irAEs and pneumonitis have 15 (5.08%). No grade 5 adverse events were observed. A total of 52 (17.63%) and 91 (30.85%) patients had single and multiple irAEs, respectively. Compared with patients without irAEs, those with irAEs had significantly higher objective response rate (ORR) (37.76% vs. 25.00%, p = 0.018) and disease control rate (DCR) (92.31% vs. 83.55%, p = 0.022). Univariate Cox analyses indicated the significant association between irAEs and improved median progression-free survival (PFS) (10.27 vs. 6.2 months, p < 0.001) and overall survival (OS) (15.4 vs. 9.2 months, p < 0.001). In multivariate analyses, irAEs were independently associated with longer PFS (p = 0.011) and OS (p = 0.002). Moreover, multivariate analysis revealed that cycles > 8, radiation, as well as antiangiogenic therapy were strongly associated with irAEs development (p < 0.001, p = 0.002, and p = 0.025, respectively).

CONCLUSION: In advanced EC, patients with irAEs showed markedly better efficacy in ORR, DCR, PFS, and OS compared with patients without irAEs.

Management of drug-induced neutropenia, thrombocytopenia, and anaemia after solid organ transplantation: A comprehensive review

Mon, 2022-10-17 06:00

J Clin Pharm Ther. 2022 Oct 17. doi: 10.1111/jcpt.13775. Online ahead of print.

ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: Advances in the development of more effective immunosuppressive drugs have increased graft survival and drug induced adverse effects. Haematological complications including neutropenia, thrombocytopenia, and anaemia are common side effects that affect the grafts' and patients' outcomes. Several studies have stated the important role of various medications in haematological complications after transplantation. They have reported the incidence and different mechanisms of drug induced cytopenia, as well as an overview of possible treatment modalities. However, there is no comprehensive protocol for the management of these complications following transplantation. This narrative review was performed to develop a comprehensive practical approach for management of drug induced haematological complications following solid organ transplantation.

METHOD: PubMed, Embase, Cochrane library, Web of Science, and Google scholar databases were searched without time limitations until March, 2021. In addition, some valid drug information data bases (Uptodate and Micromedex) were searched for detailed information until October, 2021.

RESULTS AND DISCUSSION: Several immunosuppressive and antimicrobial medications may induce neutropenia, thrombocytopenia or anaemia following transplantation. Most of these agents cause dose-related cytopenia, which resolves with dose reduction or drug withdrawal. However, any change in medications may result in negative consequences such as severe infections, bleeding, cardiovascular complications, acute allograft rejection, and graft or patient loss. Thus, cautious evaluation of the patient's condition and the pharmacological properties of the culprit medication are required.

WHAT IS NEW AND CONCLUSION: Three algorithms are presented to guide healthcare providers in the stepwise management of drug-induced neutropenia, thrombocytopenia, and anaemia after solid organ transplantation.

Drug-related immune-mediated myelopathies

Mon, 2022-10-17 06:00

Front Neurol. 2022 Sep 29;13:1003270. doi: 10.3389/fneur.2022.1003270. eCollection 2022.

ABSTRACT

Iatrogenic immune-mediated inflammatory disorders of the spinal cord are an uncommon but potentially severe complication of drug therapy for several human diseases. Particularly the introduction of novel biological agents in the treatment of systemic inflammatory disorders and cancer immunotherapy have led to a significant increase in immune-related adverse events of the central nervous system (CNS). The use of Tumor necrosis factor alpha (TNF-alpha) inhibitors in rheumatic and inflammatory bowel diseases has been associated with demyelinating and other inflammatory CNS conditions, including myelitis. The introduction of immune checkpoint inhibitors in the treatment of several human malignancies has led to an increase in drug-induced immune-related adverse events including in the CNS. Other drugs that have been associated with immune-mediated myelitis include tyrosine-kinase inhibitors and chimeric antigen receptor (CAR) T Cell therapy. A high degree of suspicion is necessary when diagnosing these conditions, as early diagnosis and treatment is crucial in preventing further neurological damage and disability. The treatment of drug-induced inflammatory myelitis typically involves administration of high-dose intravenous corticosteroids, however additional immunosuppressive agents may be required in severe or refractory cases. While most cases are monophasic and remit following discontinuation of the offending agent, chronic immunosuppressive therapy may be indicated in cases with a progressive or relapsing disease course or when a diagnosis of a specific underlying neuro-inflammatory disorder is made. Outcomes are generally favorable, however depend on the specific therapeutic agent used, the clinical presentation and patient factors. In this review we aim to describe the clinical characteristics, imaging findings and management for the most common forms of iatrogenic immune-mediated myelopathies.

Recognition and management of drug-associated oral ulceration: a review

Fri, 2022-10-14 06:00

Br Dent J. 2022 Oct;233(7):564-568. doi: 10.1038/s41415-022-5032-x. Epub 2022 Oct 14.

ABSTRACT

The number of people who are using prescribed medications is on the rise, largely due to an ageing population in the UK, but also because of early diagnosis and prompt medical management of a variety of conditions. Systemic medications may contribute to the development of oral side effects and translate into an increasing number of patients presenting in general dental practice settings. The aim of this paper is to provide an outline of oral side effects of systemic medications followed by a review of drug-associated oral ulcers (DAOUs). The paper also provides recommendations for early recognition and management of DAOUs in general dental practice settings, including referral to general medical practitioners and specialists in oral medicine.

Royal Jelly: Beneficial Properties and Synergistic Effects with Chemotherapeutic Drugs with Particular Emphasis in Anticancer Strategies

Fri, 2022-10-14 06:00

Nutrients. 2022 Oct 7;14(19):4166. doi: 10.3390/nu14194166.

ABSTRACT

Cancer is one of the major causes of death globally. Currently, various methods are used to treat cancer, including radiotherapy, surgery, and chemotherapy, all of which have serious adverse effects. A healthy lifestyle, especially a nutritional diet, plays a critical role in the treatment and prevention of many disorders, including cancer. The above notion, plus the trend in going back to nature, encourages consumers and the food industry to invest more in food products and to find potential candidates that can maintain human health. One of these agents, and a very notable food agent, is royal jelly (RJ), known to be produced by the hypopharyngeal and mandibular salivary glands of young nurse honeybees. RJ contains bioactive substances, such as carbohydrates, protein, lipids, peptides, mineral salts and polyphenols which contribute to the appreciated biological and pharmacological activities. Antioxidant, anticancer, anti-inflammatory, antidiabetic, and antibacterial impacts are among the well-recognized benefits. The combination of RJ or its constituents with anticancer drugs has synergistic effects on cancer disorders, enhancing the drug's effectiveness or reducing its side effects. The purpose of the present review is to emphasize the possible interactions between chemotherapy and RJ, or its components, in treating cancer illnesses.

In Vitro Models for Studying Chronic Drug-Induced Liver Injury

Fri, 2022-10-14 06:00

Int J Mol Sci. 2022 Sep 28;23(19):11428. doi: 10.3390/ijms231911428.

ABSTRACT

Drug-induced liver injury (DILI) is a major clinical problem in terms of patient morbidity and mortality, cost to healthcare systems and failure of the development of new drugs. The need for consistent safety strategies capable of identifying a potential toxicity risk early in the drug discovery pipeline is key. Human DILI is poorly predicted in animals, probably due to the well-known interspecies differences in drug metabolism, pharmacokinetics, and toxicity targets. For this reason, distinct cellular models from primary human hepatocytes or hepatoma cell lines cultured as 2D monolayers to emerging 3D culture systems or the use of multi-cellular systems have been proposed for hepatotoxicity studies. In order to mimic long-term hepatotoxicity in vitro, cell models, which maintain hepatic phenotype for a suitably long period, should be used. On the other hand, repeated-dose administration is a more relevant scenario for therapeutics, providing information not only about toxicity, but also about cumulative effects and/or delayed responses. In this review, we evaluate the existing cell models for DILI prediction focusing on chronic hepatotoxicity, highlighting how better characterization and mechanistic studies could lead to advance DILI prediction.

Efficacy and Safety of Ginger on the Side Effects of Chemotherapy in Breast Cancer Patients: Systematic Review and Meta-Analysis

Fri, 2022-10-14 06:00

Int J Mol Sci. 2022 Sep 24;23(19):11267. doi: 10.3390/ijms231911267.

ABSTRACT

Cancer is one of the leading causes of death in the world, with breast cancer being the most prevalent cancer. Chemotherapy-induced nausea and vomiting (CINV) is one of the most serious side effects of chemotherapy. Because the current CINV treatment option has several flaws, alternative treatment options are required. Ginger has traditionally been used to treat nausea and vomiting, and it also has anticancer properties in breast cancer cells. Based on these findings, researchers investigated whether using ginger to treat CINV in breast cancer patients is both effective and safe. We searched PubMed, Embase, Cochrane Library, CNKI, and Wanfang from inception to June 2022. Outcomes included Rhodes Index Scores of Nausea, Vomiting, and Retching, severity and frequency of CINV. Five RCTs were included. We pooled all included data and performed subgroup analysis by types of CINV. Overall, authors found that ginger was associated with a reduction in CINV. Subgroup and sensitivity analysis revealed that managing severity of acute CINV in breast cancer patients with ginger was efficient. In terms of managing delayed CINV in breast cancer patients, ginger was also statistically significant. The authors concluded that ginger may be helpful in lowering both acute and delayed CINV in breast cancer patients. Since there were no serious side effects, ginger is thought to be safe.

Prophylactic vasopressin to reduce intraoperative blood loss and associated morbidities during myomectomy: a systematic review and meta-analysis of 11 controlled trials

Fri, 2022-10-14 06:00

J Gynecol Obstet Hum Reprod. 2022 Oct 11:102485. doi: 10.1016/j.jogoh.2022.102485. Online ahead of print.

ABSTRACT

OBJECTIVE: To collate evidence from randomized controlled trials (RCTs) and nonrandomized controlled trials (NCTs) on the efficacy and safety of vasopressin versus passive control (placebo/no treatment) during myomectomy.

METHODS: Six information sources were screened until 25-June-2022. The Cochrane Collaboration tool and Newcastle-Ottawa Scale were used to evaluate the risk of bias. Data were summarized as mean difference or risk ratio with 95% confidence interval in a random-effects model.

RESULTS: Eleven studies, comprising 1067 patients (vasopressin=567 and control=500) were analyzed. For RCTs (n=8), the overall quality included 'high risk' (n=4), 'low risk' (n=2), and 'some concerns' (n=2). For NCTs (n=3), the overall quality included 'good' (n=2) and 'fair' (n=1). The mean intraoperative blood loss, mean difference in hemoglobin level, mean difference in hematocrit level, rate of perioperative blood transfusion, and mean operative time were significantly reduced in favor of the vasopressin group compared with the control group. However, there was no significant difference between both groups regarding the mean hospital stay. Pertaining to safety endpoints, after omission of an outlier study, the rate of drug-related cardiovascular adverse events did not significantly differ between both groups. There was no quantitative evidence of publication bias for the endpoint of intraoperative blood loss.

CONCLUSION: Among patients undergoing myomectomy, prophylactic administration of vasopressin was largely safe and correlated with significant reductions in intraoperative blood loss and associated morbidities compared with a passive control intervention. Nonetheless, the conclusions should be cautiously interpreted owing to the low-evidence quality and the used doses varied greatly between studies.

The Safety and Biological Activity of OTT166, a Novel Topical Selective Integrin Inhibitor for the Treatment of Diabetic Eye Disease: A Phase 1b Study

Fri, 2022-10-14 06:00

Ophthalmic Surg Lasers Imaging Retina. 2022 Oct;53(10):553-560. doi: 10.3928/23258160-20220923-02. Epub 2022 Oct 1.

ABSTRACT

BACKGROUND AND OBJECTIVES: To evaluate the safety, tolerability, and biological activity of a topical selective integrin inhibitor (OTT166) eyedrop administered BID for diabetic retinopathy (DR) and diabetic macular edema (DME).

STUDY DESIGN/MATERIALS AND METHODS: A prospective, multicenter, randomized, double-masked Phase 1b study. Subjects with nonproliferative DR and DME with central subfield thickness (CST) > 325 microns were randomized to OTT166 eyedrops (2.5% or 5%) BID for 28 days. Subjects were followed for an additional 28 days after treatment cessation.

RESULTS: Forty-four subjects were enrolled. No drug-related serious adverse events (SAEs) and two drug-related adverse events (AEs) were reported. OTT166 was well-tolerated with no evidence of ocular toxicity. Best-corrected visual acuity (BCVA) remained stable. Mean central retinal thickness (CRT) overall was variable: +12.8/+1.8 microns at Day 28 (end of treatment) and -50.3/+5.5 microns at Day 56 (end of study) for the 2.5% and 5% groups, respectively. Median CRT overall demonstrated consistent reduction by end of study: -39.0/-16.5 microns for the 2.5% and 5% groups, respectively. Median responses were greater in the treatment-naïve group (-41.5/-26.0 microns for the 2.5% and 5% groups, respectively). Thirty-seven percent of 'responder' subjects exhibited a mean reduction in CRT of 46.6 microns on optical coherence tomography (OCT) at end of treatment (Day 28) which persisted to end of the study (Day 56) - mean reduction of 67.4 microns, suggesting a durable effect.

CONCLUSION: OTT166 eyedrops were safe, well-tolerated, and demonstrated biological activity in 37% of responders. These results warrant further evaluation of OTT166 eyedrops. [Ophthalmic Surg Lasers Imaging Retina 2022;53:553-560.].

Effects of Toxic Lithium Levels on ECG-Findings from the LiSIE Retrospective Cohort Study

Fri, 2022-10-14 06:00

J Clin Med. 2022 Oct 8;11(19):5941. doi: 10.3390/jcm11195941.

ABSTRACT

(1) Background: Few studies have explored the impact of lithium intoxication on the heart. (2) Methods: We examined electrocardiogram (ECG) changes associated with lithium intoxication in the framework of the LiSIE (Lithium-Study into Effects and Side Effects) retrospective cohort study. We analysed ECGs before, during, and after intoxication. (3) Results: Of the 1136 patients included, 92 patients had experienced 112 episodes of lithium intoxication. For 55 episodes, there was an ECG available at the time; for 48 episodes, there was a reference ECG available before and/or after the lithium intoxication. Lithium intoxication led to a statistically significant decrease in heart rate from a mean 76 beats/min (SD 16.6) before intoxication to 73 beats/min (SD 17.1) during intoxication (p = 0.046). QTc correlated only weakly with lithium concentration (ρ = 0.329, p = 0.014). However, in 24% of lithium intoxication episodes, there were QT prolongations. In 54% of these, QTc exceeded 500 ms; patients with chronic intoxications being more affected. (4) Conclusions: Based on summary statistics, effects of lithium intoxication on HR and QTc seem mostly discrete and not clinically relevant. However, QT prolongation can carry a risk of becoming severe. Therefore, an ECG should always be taken in patients presenting with lithium intoxication.

Int J Mol Sci. 2022 Oct 10;23(19):12032. doi: 10.3390/ijms231912032.

ABSTRACT

Different strategies have been investigated for a more satisfactory treatment of advanced breast cancer, including the adjuvant use of omega-3 polyunsaturated fatty acids (PUFAs). These nutritional compounds have been shown to possess potent anti-inflammatory and antiangiogenic activities, the capacity to affect transduction pathways/receptors involved in cell growth and to reprogram tumor microenvironment. Omega-3 PUFA-containing nanoformulations designed for drug delivery in breast cancer were shown to potentiate the effects of enclosed drugs, enhance drug delivery to target sites, and minimize drug-induced side effects. We have critically analyzed here the results of the most recent studies investigating the effects of omega-3 PUFA-containing nanoformulations in breast cancer. The anti-neoplastic efficacy of omega-3 PUFAs has also been convincingly demonstrated by using preclinical in vivo models of ovarian cancer. The results obtained are critically analyzed here and seem to provide a sufficient rationale to move to still lacking interventional clinical trials, as well as to evaluate possible advantages of enclosing omega-3 PUFAs to drug-delivery nanosystems for ovarian cancer. Future perspectives in this area are also provided.
