RESUMO

OBJECTIVE: To determine the relationship of Neutrophil Lymphocyte Ratio (NLR), Monocyte Lymphocyte Ratio (MLR), and Neutrophil Monocyte Ratio (NMR) with treatment response in Pulmonary Tuberculosis (PTB) patients during intensive phase treatment (IPT). METHODS: This analytical cross-sectional study was conducted at Ojha Institute of Chest Diseases (OICD), Dow University of Health Sciences, from February to December 2021. 100 patients were enrolled using purposive sampling technique. Both male and female of age 18 and above, rifampicin sensitive newly diagnosed cases of PTB by Acid Fast Bacilli (AFB) microscopy and Gene Xpert MTB/RIF were included. SPSS version 26 was used to analyze data. Numerical data was expressed in median and interquartile range and categorical data was expressed in frequencies and percentages. RESULTS: Out of total 100 patients, 81% (n = 81) showed treatment response with negative AFB Sputum Smear Microscopy (SSM) after 2nd month. Out of 81% (n = 81) of the patients who achieved treatment response, 83.9% (n = 68) also had decreased NLR, 85.2% (n = 69) had decreased MLR and 83.9% (n = 68) had decreased NMR from baseline. However 19% (n = 19) did not achieved treatment response with positive AFB SSM after 2nd month of ATT (Anti tuberculosis treatment), among them 10.52% (n = 2) were INH resistant with no decrease in all the ratios after 2nd month. CONCLUSION: Leukocyte ratios decreased significantly from baseline as PTB was treated in patients who achieved treatment response with negative AFB SSM after two months of ATT and hence these ratios could be used as markers to monitor the treatment response.

RESUMO

The capsule is a major virulence factor for Streptococcus pneumoniae which causes global morbidity and mortality. It is already known that there are few conserved genes in the capsular biosynthesis pathway, which are common among all known serotypes, called CpsA, CpsB, CpsC and CpsD. Inhibiting capsular synthesis can render S. pneumoniae defenseless and vulnerable to phagocytosis. The Inhibitory potential of active Zingiber officinale compounds was investigated against the 3D (3-dimensional) structural products of Cps genes using in silico techniques. A 3D compound repository was created and screened for drug-likeness and the qualified compounds were used for molecular docking and dynamic simulation-based experiments using gallic acid for outcome comparison. Cavity-based docking revealed five different cavities in the CpsA, CpsB and CpsD proteins, with gallic acid and selected compounds of Zingiber in a binding affinity range of -6.8 to -8.8 kcal/mol. Gingerenone A, gingerenone B, isogingerenone B and gingerenone C showed the highest binding affinities for CpsA, CpsB and CpsD, respectively. Through the Molegro Virtual Docker re-docking strategy, the highest binding energies (-126.5 kcal/mol) were computed for CpsB with gingerenone A and CpsD with gingerenone B. These findings suggest that gingerenone A, B and C are potential inhibitors of S. pneumoniae-conserved capsule-synthesizing proteins.

RESUMO

Left Ventricular Non-Compaction Cardiomyopathy (LVNC) is a rare myocardial disorder characterized by abnormal myocardial tissue formation in which the left ventricular wall appears to be trabecular with prominent intertrabecular recesses. The diagnosis of LVNC is predominantly reliant on cardiac imaging, namely thoracic echocardiography, however, cardiac MRI is indicated in conditions in which echocardiography is inconclusive. Diagnostic criteria for both echocardiography and cardiac MRI differ, however, the general principle of diagnosis is a comparison of the thickness of non-compacted to compacted myocardial tissue. The management of LVNC is nearly identical to that of Heart Failure with reduced Ejection Fraction (HFrEF), however, anticoagulation is an additional measure of management to the thrombogenic nature of non-compacted myocardial tissue. Here, we discuss a case of LVNC and the current data on its management.

RESUMO

BACKGROUND Acute aortic insufficiency can be secondary to multiple conditions, including infective endocarditis, aortic root pathologies (eg, dissection, aortitis), or traumatic injury. Aortitis involves a broad spectrum of disorders characterized by inflammatory changes in the aortic wall. This pathology can be subsequently classified depending on its etiology into inflammatory and infectious causes. Large-vessel vasculitis (giant-cell arteritis, Takayasu arteritis, and IgG4-related vasculitis) is the most common non-infectious causes of aortitis. Giant-cell aortitis usually lacks the classic clinical findings of giant-cell arteritis such as headache, visual symptoms, or jaw claudication, which can be a diagnostic challenge. However, clinicians should have a high index of suspicion, since this pathology can evolve into potentially life-threatening conditions, including aortic aneurysm, aortic wall rupture, and aortic acute dissection. CASE REPORT We present a case of a 76-year-old woman who presented to the Emergency Department (ED) with shortness of breath associated with orthopnea, paroxysmal nocturnal dyspnea, and mild productive cough with white sputum. A transthoracic echocardiogram demonstrated reduced left ventricular ejection fraction, dilated left ventricle, and severe aortic insufficiency. Cardiac catheterization revealed mild non-obstructive coronary arteries and severe aortic regurgitation. The surgical pathology report of the portion of the aorta was consistent with giant-cell aortitis. CONCLUSIONS In this article, we present a case of giant-cell aortitis as an unusual etiology of acute aortic insufficiency, which is most probably under-detected in clinical practice. In addition to describing the case, we aim to highlight the importance of proper ascending aorta evaluation in patients presenting with new-onset aortic regurgitation and heart failure to prevent associated morbidity and mortality.

RESUMO

Radial artery spasm (RAS) is the most common cause of transradial access site crossover and is a common intra-procedural complication. RAS incidence can lead to radial artery occlusion (RAO) postprocedure, preventing the radial artery as a future access site. We evaluated the efficacy of nitroglycerin preventing RAS and RAO during transradial catheterization discussing the different routes of administration, including topical, subcutaneous, and intra-arterial. A systematic review and meta-analysis included all relevant articles until April 23, 2022. We searched six databases Google Scholar, Web of Science, SCOPUS, EMBASE, PubMed (MEDLINE), and CENTRAL. We registered our review protocol in PROSPERO with ID: CRD42022330356. We included 11 trials with 5814 patients. Compared to placebo, the pooled analysis favored subcutaneous nitroglycerin in preventing RAS (risk ratio [RR]: 0.57 with 95% confidence interval [CI] [0.43-0.77], p = .0003) and RAO (RR: 0.39 with 95% CI [0.16-0.98], p = .05). In contrast to the intra-arterial nitroglycerin that showed nonstatistically significant results in preventing RAS and RAO (RR: 0.8 with 95% CI [0.63-1.02], p = .07)- (RR: 0.78 with 95% CI [0.6-1.01], p = .06)), respectively. Also, topical nitroglycerin did not prevent RAS (RR: 0.73 with 95% CI [0.42-1.24], p = .24). Compared with placebo, subcutaneous nitroglycerin during transradial catheterization reduced the incidence of RAS and RAO. Meanwhile, Intra-arterial and topical nitroglycerin did not show statistically significant outcomes. Subcutaneous nitroglycerin may be a practical and cost-effective technique to facilitate transradial catheterization; however, more RCTs are needed to evaluate the subcutaneous versus intra-arterial nitroglycerin administration.

RESUMO

The heart is a rare site of metastatic lesions of malignancies. Cardiac metastasis may go unrecognized till autopsy, and about half of all newly diagnosed lung cancer patients have metastasis to another organ. Due to the absence of early symptoms, the clinical diagnosis of cardiac metastasis is challenging. Even when they are symptomatic, these symptoms may be masked by the clinical features of primary cancer. Noncardiac neoplasms may spread to the heart through lymphatic or hematogenous dissemination, local extension, or a transvenous route. Here, we report a case of a 56-year-old male with lung mass extending from the right upper lobe to the left atrium was associated with mass effect on superior vena cava and left brachiocephalic vein.

RESUMO

Despite the lack of direct evidence that hypertension increases the likelihood of new infections, hypertension is known to be the most common comorbid condition in COVID-19 patients and also a major risk factor for severe COVID-19 infection. The literature review suggests that data is heterogeneous in terms of the association of hypertension with mortality. Hence, it remains a topic of interest whether hypertension is associated with COVID-19 disease severity and mortality. Herein, we perform a multicenter retrospective analysis to study hypertension as an independent risk for in-hospital mortality in hospitalized COVID-19 patients. This multicenter retrospective analysis included 515 COVID-19 patients hospitalized from March 1, 2020 to May 31, 2020. Patients were divided into two groups: hypertensive and normotensive. Demographic characteristics and laboratory data were collected, and in-hospital mortality was calculated in both groups. The overall mortality of the study population was 25.3% (130 of 514 patients) with 96 (73.8%) being hypertensive and 34 (26.2%) being normotensive (p-value of 0.01, statistically non-significant association). The mortality rate among the hypertensive was higher as compared to non-hypertensive; however, hypertensive patients were more likely to be old and have underlying comorbidities including obesity, diabetes mellitus, coronary artery disease, congestive heart failure, stroke, chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), and cancer. Therefore, multivariable logistic regression failed to show any significant association between hypertension and COVID-19 mortality. To our knowledge, few studies have shown an association between hypertension and COVID-19 mortality after adjusting confounding variables. Our study provides further evidence that hypertension is not an independent risk factor for in-hospital mortality when adjusted for other comorbidities in hospitalized COVID-19 patients.

RESUMO

The left ventricular outflow tract is a region of the left ventricle that lies between the anterior leaflet of the mitral valve and the ventricular septum. Dynamic left ventricular outflow tract obstruction (LVOTO) has classically been observed in patients with hypertrophic obstructive cardiomyopathy (HOCM) where it occurs secondary to asymmetric septal hypertrophy and systolic anterior motion (SAM) of the mitral valve. However, there are some instances that lead to hypercontractility of the myocardium, and with a combination of other physiological conditions, result in SAM of a mitral valve leaflet, leading to LVOTO in the absence of phenotype. We present such a case of an acute inferolateral wall myocardial infarction that was complicated by cardiogenic shock, requiring an intra-aortic balloon pump (IABP) and inotropic support which paradoxically provoked LVOTO. A reduction in IABP counterpulsation from 1:1 to 1:3 and the addition of intravenous fluids and a beta blocker resulted in significant improvement in blood pressure with rapid tapering of pressors. Inotropes and IABP, although helpful in cardiogenic shock, have the potential to induce or worsen the LVOTO, which can lead to a vicious cycle of worsening hypotension and increasing adrenergic drive that further deteriorates myocardial viability. Timely diagnosis with an echocardiogram and the withdrawal of inotropic and IABP support has the potential to improve haemodynamics and, thereby, outcome. LEARNING POINTS: Dynamic left ventricular outflow tract obstruction (LVOTO) should be one of the differentials in patients with cardiogenic shock, especially if it is refractory in the setting of an intra-aortic balloon pump.The diagnosis of LVOTO by echocardiography should result in immediate implementation of therapy to eliminate the factors that can potentially intensify the obstruction.

RESUMO

Ludwig's angina is a bacterial infection of the tongue and floor of the mouth. It can be life-threatening if not treated promptly. Treatment includes IV antibiotics and, in some cases, surgical intervention. In this report, we describe a case with an unusual presentation. Early recognition of the condition in such cases is vital to prevent potential complications. LEARNING POINTS: Ludwig's angina, even though a well-established clinical entity, can be hard to recognize clinically.Early recognition of the condition is vital for the prevention of complications.A low threshold for surgical treatment should be maintained when surgery is indicated.

RESUMO

Left ventricular thrombus (LVT) formation is a serious clinical complication of low-flow states that may be seen in an ischaemic, arrhythmic heart. While LVT formation has a poor prognosis, in the setting of myocardial infarction it is usually a result of post-infarct sequelae such as left ventricle aneurysms, and inflammatory changes from damaged tissue, with the LVT taking several days to form. Arrythmias such as ventricular tachycardia (VT) or ventricular fibrillation (VF) may also lead to thrombus formation, as they contribute to stasis due to decreased cardiac output. Large anterolateral myocardial infarctions can cause electrical or arrhythmic storm, characterized by more than three episodes of VT or VF in a 24-hour period. This prolonged state of dyskinesis further increases the risk of thrombosis, creating a compounding effect. Here, we report the case of a patient who had a VF cardiac arrest with electrical storm secondary to anterolateral myocardial infarction complicated with LVT formation found on echocardiogram after the cardiac arrest, which was absent on presentation. This thrombus formation occurred particularly early during the course of the patient's arrest, possibly due to the compounding factors increasing the risk of thrombosis. Herein, we discuss in detail the risk factors for LVT formation, its mechanism and management options. A review of the literature also shows that LVT formation in the acute phase of arrest, as seen in our patient, is rare. LEARNING POINTS: Left ventricular thrombus (LVT) formation occurs 3-14 days after myocardial infarction, but in the setting of concomitant ventricular fibrillation arrest, may occur within the first 24 hours.Risk factors for LVT formation include a large infarct, anterior/anterior apical infarction, decreased ejection fraction (particularly <30-35%), left ventricular aneurysm, and delayed time to revascularization.Although diagnosis is generally made on transthoracic echocardiography with intravenous contrast, cardiac MRI with contrast has better sensitivity and specificity.Treatment consists of anticoagulation with a vitamin K antagonist or heparin for 3-6 months with a repeat echocardiogram to confirm the thrombus has organized or resolved. Further trials are needed to assess the efficacy of direct oral anticoagulants.

RESUMO

A pericardial cyst is one of the rare causes of mediastinal masses. Most of the cases are secondary to congenital incomplete fusion of the pericardial sac. More than two-thirds of the cases are present in the right cardiophrenic angle, and the left cardiophrenic angle is the second most common location. In our study, we illustrated an incidental finding of the pericardial cyst in a patient who presented with nonspecific symptoms and was found to have a left-sided cardiophrenic pericardial cyst, which is only found in about 20% of the cases. A CT scan and echocardiogram confirmed the diagnosis of a 4.39-centimeter cyst with no signs of complications like tamponade or pericarditis. As the patient's symptoms resolved, outpatient follow-up with serial echocardiogram was advised. Through this report, we aim to raise awareness of the importance of further investigation for nonspecific symptoms like atypical chest tightness and differentiating simple pericardial cysts from other pericardial lesions. Based on the symptoms, size, and compression effect of the cyst, management may vary from serial echocardiogram to aspiration or surgical resection.

RESUMO

Wolf-Parkinson-White (WPW) syndrome is a congenital heart condition in which the atrioventricular (AV) node is bypassed by an accessory pathway that connects the atria and ventricle directly. WPW syndrome in patients with a history of peripartum cardiomyopathy (pregnancy-related cardiomyopathy) is associated with a high risk of morbidity and mortality secondary to failure of the pump and the conduction system of the heart. Management of these cases deals with arrhythmia and systolic heart failure, which becomes more challenging in pregnant patients as it requires treatment methods that minimize risks to the fetus. We report a case of a young female patient with WPW syndrome and postpartum cardiomyopathy presenting with symptomatic arrhythmias (tachycardia).

RESUMO

The eustachian valve (EV) is a vestigial structure found at the junction of the inferior vena cava and the right atrium, a remnant of the embryological sinus venosus that may persist throughout life. Right-sided infective endocarditis of the eustachian valve remains a distinctly rare and under-diagnosed entity. Commonly known risk factors of eustachian valve endocarditis (EVE) are intravenous drug use, in-dwelling intracardiac devices, and central lines, although more recently immunocompromised states, e.g. uncontrolled diabetes mellitus and old age, have been recognized as risk factors for the disease. Although Staphylococcus aureus has been the most commonly implicated organism, cases of infections with gram-negative organisms are emerging. We present a 47-year-old male with uncontrolled type 1 DM who initially presented to the ED with complaints of low back pain and dysuria and was later found to have eustachian valve endocarditis ultimately treated with intravenous antibiotics.

RESUMO

Cocaine is considered a leading non-opioid cause of drug overdose in the US. It acts as a sympathomimetic and increases the amount of catecholamines, thereby increasing the risk of ventricular irritability and resultant arrhythmias. Its sodium (Na) channel blockage is the principal mechanism behind the Brugada pattern on an electrocardiogram (ECG), which is often transient but is indistinguishable from that of Brugada syndrome, the autosomal dominant channelopathy. We are presenting a case of a 32-year-old male with a history of cocaine and nicotine abuse, who sought medical attention for sudden-onset palpitations and pressure-like chest pain after having snorted an impressive amount of cocaine. His ECG depicted a classical Brugada pattern with ST-elevation with T inversion in V1; however, previous ECGs were normal without ST changes, signifying the Brugada pattern unmasked by cocaine use. Other investigations including stress tests and nuclear imaging were equivocal. His symptoms as well as the ECG pattern reverted to baseline signifying the presence of Brugada phenotype in the absence of channelopathy. Hence, as a sodium channel blocker, cocaine may unmask latent Brugada syndrome in asymptomatic patients without a family history. Recognizing Brugada syndrome on ECG is vital to avoid misdiagnosis and mistreatment of the patient with and without a genetic predisposition.

RESUMO

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV- 2) was declared a pandemic by WHO in March 2020. The causative organism has since undergone a series of mutations. COVID-19 primarily being a respiratory illness causes pre-existing pulmonary diseases to show worse clinical outcomes. About one-third of the world's population is thought to be infected with latent Mycobacterium tuberculosis (MTB). Both previous and newly developed tuberculosis (TB) infection are risk factors for COVID-19 and are associated with poor outcomes. T lymphocytes play a pivotal role in defense against MTB and with evidence suggesting depletion of T lymphocytes in COVID-19, it can be postulated that COVID-19 can increase the risk of reactivation of latent TB.  Given that a large population around the globe is infected with latent tuberculosis, it is interesting to study and note cases where the virus leads to the reactivation of latent tuberculosis infection. Herein, we present a 76-year-old Brazilian male recently treated for COVID-19 pneumonia, presenting with new-onset cough and weakness diagnosed with latent MTB reactivation.

RESUMO

Aortic dissection is a relatively uncommon, although catastrophic, disease which requires early and accurate diagnosis and treatment for patient survival. Aortic dissection can be difficult to diagnose due to the diverse symptom presentation, which can lead to later diagnosis, resulting in a higher mortality rate. Here we present a case of type A aortic dissection with a varied symptom presentation, highlighting the importance of early detection and the Bentall procedure for management of such cases. A 50-year-old man with no known medical history presented with bilateral lower extremity swelling and fatigue for 2 weeks. The patient denied any chest pain or dyspnoea. Vital signs showed blood pressure of 160/76 mmHg, pulse of 103 bpm, respiratory rate of 18, and temperature of 36.7°C. Laboratory findings indicated a BNP of 1901 pg/ml and troponin of 0.5 ng/ml. An initial diagnosis of decompensated heart failure was made, and IV Lasix was started. Subsequently, an echocardiogram indicated an EF of 50-55% and ascending dissection of the aorta. A CT angiogram of the chest and abdomen confirmed this diagnosis. This patient presented with unusual symptoms of aortic dissection without the typical presentation of chest pain. It is important to consider aortic dissection in a cardiac-related case as prompt imaging can help confirm the diagnosis. We explore the risks and benefits of the Bentall procedure for the management and early detection of aortic dissection. LEARNING POINTS: The absence of chest pain does not rule out aortic dissection as 50% of patients are pain free.It is critical to diagnose aortic dissection early in the disease course as mortality increases by 1% per hour from symptom onset.The aim of this study is also to raise awareness among healthcare professionals about the Bentall procedure in patients with type A aortic dissection involving the aortic valve.

RESUMO

The serum osmolar gap, defined as the difference between measured osmolality and calculated osmolarity, is a convenient method to screen for toxins in serum. In normal circumstances, the difference between the two is 6-10 mol/kg. Typical contributors to serum osmolarity are sodium bicarbonate, sodium chloride, glucose and urea. An elevated gap, defined as a difference >10 mol/kg, can occur if a sufficient quantity of an additional solute other than those mentioned above is present in the serum or there are inaccuracies in sodium measurement secondary to hyperlipidaemia and hyperproteinaemia. An elevated serum osmolar gap should thus prompt clinicians to check for toxic alcohol levels. Treatment with fomepizole should not be delayed if suspicion is high. Isolated diabetic ketoacidosis can occasionally present with an elevated osmolar gap in the absence of concomitant alcohol ingestion. This finding is attributed to the production of acetone and glycerol. We describe the case of a 62-year-old man presenting with diabetic ketoacidosis/hyperosmolar hyperglycaemic state and an elevated osmolar gap in the absence of toxic alcohol ingestion. LEARNING POINTS: The osmolar gap is the difference between the measured and the calculated serum osmolarity and should be calculated in all patients presenting with elevated serum osmolarity; if elevated, toxic alcohol ingestion should be considered and prophylactic treatment with fomepizole immediately administered if the index of suspicion is high.Although toxic alcohol ingestion is one of the common causes of an elevated osmolar gap, hyperlipidaemia, hyperproteinaemia and less occasionally lactic acidosis and ketoacidosis have also been implicated.In the setting of ketoacidosis, the osmolar gap can be elevated in the absence of toxic alcohol ingestion, is attributed to increased production of acetone and glycerol, and is responsive to treatment with insulin and intravenous fluids.

RESUMO

Acute flare of multiple sclerosis usually presents with sensorimotor deficits in limbs or one side of the face, optic neuritis, internuclear ophthalmoplegia, and/or cerebellar signs and symptoms. Isolated aphasia is observed only in a handful of cases. Herein, we present a case of a patient who presented with isolated transcortical motor aphasia. Initial thought was that the patient was having a cerebrovascular accident as he had a history of uncontrolled hypertension. It was only later found on magnetic resonance imaging (MRI) of the brain that the patient had demyelinating lesions compatible with his new symptoms. He exhibited an excellent response to intravenous methylprednisolone therapy and was discharged with outpatient evaluation for immunotherapy.

RESUMO

Brugada syndrome is an autosomal dominant genetic disorder that primarily affects myocardial sodium channels and has been associated with an increased risk of ventricular tachyarrhythmias and sudden cardiac death. Here, we report a case of a 58-year-old Hispanic male with a history significant for prior pulmonary tuberculosis infection who presented with pleuritic left-sided chest pain associated with body aches, productive cough, fevers, and chills and was found to be positive for SARS-CoV-2 by real-time reverse-transcription-polymerase chain reaction (rRT-PCR). Electrocardiogram (ECG, EKG) on presentation demonstrated a coved ST-segment elevation in V1-V2, suggesting Brugada pattern type 1 without evidence of ischemic changes. EKG changes normalized once fever and hyponatremia improved.

RESUMO

Since the beginning of the coronavirus disease 2019 (COVID19) pandemic, several cases of myocarditis related to COVID-19 infection have been reported. These cases range from asymptomatic disease to fulminant heart failure or sudden cardiac death. Cardiac injury has also been found in asymptomatic patients and patients who recovered from the disease. Data regarding cardiovascular involvement due to COVID-19 infection are still limited, and the actual prevalence of myocarditis due to COVID-19 infection is still unknown. We present a case of focal myopericarditis in a patient recently recovered from COVID-19 pneumonia with electrocardiogram showing ST elevation in inferior and lateral leads. This case highlights the need for studying the long-term cardiovascular complications of COVID-19 and reinforces the use of cardiac magnetic resonance (CMR) and cardiac biomarkers in the diagnosis of COVID-19-related myocarditis.
