A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also known as coronavirus disease 2019 (COVID-19), emerged in Wuhan, China, and rapidly spread across the world. Today, we present an interesting case of a patient with no prior history of pulmonary disease who was diagnosed with COVID-19, recovered after a prolonged hospital course, and was diagnosed with pulmonary fibrosis requiring oxygen therapy thereafter. The patient is currently on pirfenidone and has had a significant improvement in his functional status. His oxygen requirements have decreased, and repeat computed tomography (CT) scanning has demonstrated improvement in the extent of his pulmonary fibrosis. This case highlights the possibility of pulmonary fibrosis being a major complication among COVID-19 survivors and the importance of using pirfenidone in the management of such cases.
Acute myocarditis is commonly caused by viral infections resulting from viruses such as adenovirus, enteroviruses, and, rarely, coronavirus. It presents with nonspecific symptoms like chest pain, dyspnea, palpitation, or arrhythmias and can progress to dilated cardiomyopathy or heart failure. Fulminant myocarditis is a potentially life-threatening form of the condition and presents as acute, severe heart failure with cardiogenic shock. In this report, we discuss a case of a 41-year-old female who presented with cough and chest pain of two days' duration. The patient had a new-onset atrial flutter. Her chest auscultation revealed bilateral crackles. Laboratory workup revealed elevated troponin levels, and the patient tested positive for coronavirus disease 2019 (COVID-19) by nasopharyngeal swab polymerase chain reaction (PCR). Transthoracic echocardiogram revealed a low left ventricular (LV) ejection fraction of 35-40% compared to 55% one year prior, as well as a granular appearance of LV myocardium. The patient's condition subsequently improved clinically and she was discharged home. Due to cardiac involvement and characteristic myocardial appearance on the echocardiogram, cardiac magnetic resonance (CMR) imaging was performed for further evaluation about two months from the date of admission. CMR showed extensive myocardial inflammation with a typical pattern of sub-epicardial and mid-wall delayed enhancement, confirming the diagnosis of myocarditis. This case highlights myocarditis as a potential complication of COVID-19 that requires early diagnosis and proper management to improve patients' quality of life. Additionally, we highlight the features of myocarditis on CMR in the acute phase and two months after clinical recovery.
Tenecteplase (TNK) is a promising candidate to replace alteplase as the standard of care for acute ischemic stroke (AIS); however, the optimal dosage is still to be investigated. Therefore, we aim to evaluate the safety and efficacy of TNK versus alteplase and to investigate the optimal TNK dosage. A systematic review, pairwise, and network meta-analysis synthesizing randomized controlled trials (RCTs) from WOS, SCOPUS, EMBASE, and PubMed until July 26th, 2022. We used the risk ratio (RR) for dichotomous outcomes presented with the corresponding 95% confidence interval (CI). We registered our protocol in PROSPERO with ID: CRD42022352038. Nine RCTs with a total of 3,707 patients were included. TNK significantly led to complete recanalization (RR: 1.27 with 95% CI [1.02, 1.57], P = 0.03); however, we found no difference regarding early neurological improvement (RR: 1.07 with 95% CI [0.94, 1.21], P = 0.33) and excellent neurological recovery (RR: 1.03 with 95% CI [0.96, 1.10], P = 0.42). Also, TNK was similar to alteplase regarding mortality (RR: 0.99 with 95% CI [0.82, 1.18], P = 0.88), intracranial haemorrhage (RR: 1.00 with 95% CI [0.85, 1.18], P = 0.99), and parenchymal hematoma (RR: 1.13 with 95% CI [0.83, 1.54], P = 0.44). TNK in the dose of 0.25 mg is a viable candidate to displace alteplase as the standard of care in patients with an AIS within 4.5 h of presentation due to its better rate of early neurological recovery and non-inferiority in terms of safety outcomes. However, the evidence regarding TNK’s role in AIS presenting after 4.5 h from symptoms onset, wake-up stroke, and minor stroke/TIA is still lacking, necessitating further double-blinded pragmatic RCTs in this regard.
This review aims to evaluate if there are clinical benefits of curcumin (CUR) in patients with polycystic ovary syndrome (PCOS). Electronic databases (PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar) were systematically searched to identify only randomized clinical trials (RCTs) that assessed CUR in patients with PCOS from inception to May 5, 2021. Five RCTs were included with a total of 296 patients, with 148 among the CUR groups and 148 patients among the control group. Revised Cochrane risk‐of‐bias tool for randomized trials was used to assess the risk of bias, three RCTs provided a low risk of bias and two provided a high risk of bias. Compared with the control group, CUR was associated with a statistically significant improvement in the glycemic control including fasting blood glucose (MD = −3.67; 95% CI = [−5.25, −2.08], p < .00001), insulin level (MD = −1.91; 95% CI = [−2.97, −0.84], p = .0005), homeostasis model assessment of insulin resistance (MD = −0.55; 95% CI = [−0.83, −0.27], p = .0001), and quantitative insulin sensitivity check index (MD = 0.01; 95% CI = [0.00, 0.02], p = .0005). The mean difference in total cholesterol was also statistically significant (MD = −15.55; 95% CI = [−30.33, −0.76], p < .04). The rest of the secondary outcomes, including LDL, HDL, sex hormone, body weight, and CRP, were not statistically significant. This review concluded that among patients with PCOS, the use of CUR demonstrated a significant difference from the control group for glycemic control. Those findings suggest that CUR confers clinical benefits in patients with PCOS. However, due to the limited number of the included studies, further high‐quality studies are needed to establish the clinical efficacy of the CUR.
Objective Lymphatic filariasis is a serious public health issue. Recent studies showed that a single dosage of triple therapy (Ivermectin, Diethylcarbamazepine, and Albendazole) is more effective than dual therapy (Ivermectin plus Albendazole or Diethylcarbamazepine plus Albendazole) for clearing microfilaria from the blood. We aimed to evaluate the efficacy and safety of triple therapy versus dual therapy in patients infected with microfilaria and communities endemic to lymphatic filariasis. Methods For this systematic review and meta‐analysis, we searched MEDLINE, EMBASE, SCOPUS, Cochrane Central Register of Controlled Trials, and Web of Science until 24th June 2021. We included randomized control trials that compared triple with dual therapy given to patients with lymphatic filariasis or endemic communities. This study was registered with PROSPERO (CRD42021266724). Results We included eight articles after the screening process. Triple therapy caused more clearance of microfilaria in the blood (RR: 1.52; 95% CI: 1.15, 2.02; p = 0.003), while dual therapy caused more clearance of the circulating filariae antigen in the blood (RR: 0.76; 95% CI: 0.65, 0.88; p = 0.0003), both 12 months after drug administration. The triple therapy had a similar adverse effect compared with the dual therapy group. Conclusion Based on the greater efficacy in the clearance of microfilaria and the safety of triple therapy, it constitutes a better strategy for the eradication programs of lymphatic filariasis in endemic regions. However, further studies are needed to confirm our results.
Accumulating evidence has been reported regarding the effect of curcumin as a dietary antiviral on patients with COVID-19; however, findings are controversial. Our systematic review aimed to evaluate the effects of curcumin in patients with COVID-19. Electronic databases (PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar) were systematically searched to identify only randomized clinical trials (RCTs) that assessed curcumin in patients with COVID-19 from inception to September 23, 2021 relevant keywords. The Cochrane risk-of-bias tool for randomized trials was used to evaluate the risk of bias. After a critical review of 1,098 search hits, only six RCTs were selected for discussion. A total of 480 patients were included, with 240 amongst the curcumin groups and 240 in the control group. The lymphocyte count was significantly higher in the curcumin group compared to the placebo group. Curcumin was found to decrease the number of T-helper 17 cells, downregulate T-helper-17 cell-related factors, reduce levels of T-helper-17 cell-related cytokines, yet increase the gene expression of Treg transcription factor forkhead box P3 (FOXP3), and decrease T-Box transcription factor 21 (TBX21). Our review revealed that curcumin might have a positive effect on relieving COVID-19 related inflammatory response due to its powerful immune-modulatory effects on cytokines production, T-cell responses, and gene expression. These findings suggest that curcumin confers clinical benefits in patients with COVID-19. However, due to the limited number of the included studies, further high-quality studies are needed to establish the clinical efficacy of the curcumin.
The importance of this review lies in its study of the risk of sudden cardiac death (SCD) and sudden cardiac arrest (SCA) in people living with the human immunodeficiency virus (PLWH). To the best of our knowledge, this is the first review investigating the effect of the human immunodeficiency virus (HIV) on SCD and SCA. The review's objective was to determine the risk of SCD and SCA in PLWH. To do this, the electronic databases Ovid MEDLINE, EMBASE, Cochrane Central, Scopus, and Google Scholar were systematically searched to identify eligible studies published before January 31, 2021. Reference lists of the included studies were searched for further identification of relevant studies. The search terms included: "Sudden Cardiac Death," "Sudden Cardiac Arrest," "Human Immunodeficiency virus," "HIV," "Acquired immunodeficiency syndrome," and "AIDS." Only observational studies that assessed the association between SCD and SCA in PWLH were selected. Data were extracted by two independent authors who screened titles, abstracts, and articles to meet the inclusion criterion. Quality assessment was done by using modified Downs and Black checklist. A total of seven studies were included in this review. Five studies revealed a higher incidence of SCD in PLWH, two of which focused on patients with HIV and low left ventricular ejection fraction (LVEF). The other two studies were about the association of HIV and SCA. Studies reported that PLWH had a three-to five-fold higher incidence of SCD as compared to non-HIV patients. HIV patients with low LVEF had a higher incidence of SCD than HIV patients with normal LVEF. PLWH had a higher incidence of SCA and less successful cardiopulmonary resuscitation (CPR) as compared to patients without HIV. After adjusting for various confounders in multiple studies, all the studies reported a higher incidence of SCD in PLWH. To conclude, PLWH is at an increased risk of SCD and SCA. Some risk factors for this include LVEF, viral load (VL), and the cluster of differentiation 4 (CD4) count. There is a paucity of data on the mechanisms involved, although a higher prevalence of cardiac fibrosis and interstitial fibrosis in PLWH may play a role. Because of the general suboptimal quality of the heterogeneous nature of the current evidence, further, rigorous studies are needed to determine the association of increased risk of SCD and SCA in PLWH.
