Background: The development of COVID-19 having been set apart as the third presentation of an exceptionally pathogenic coronavirus into the human populace after the extreme intense SARS-COV and MERS-COV in the twenty-first century. The infection itself doesn’t make a crucial commitment to mortality, anyway “cytokine storm” created by the unreasonable invulnerable reaction activated by the virus can result in a hyperinflammatory response of lung tissues and deadly lung injury, and in this way increment death rate. In this manner, immunomodulatory medications ought to likewise be remembered for treatment of COVID-19.
Presentation of the hypothesis: the virus particles invade the respiratory mucosa firstly and infect other cells, triggering a series of immune responses and the production of cytokine storm in the body, which may be associated with the critical condition of COVID-19 patients. Once a cytokine storm is formed, the immune system may not be able to kill the virus, but it will certainly kill many normal cells in the lung, which will seriously damage the of lung function. Patients will have respiratory failure until they die of hypoxia. It is not yet clear what the death rate of Covid-19 will be, though the best estimate right now is that it is around 1 percent, 10 times more lethal than seasonal flu due to cytokines storm which trigger a violent attack by the immune system to the body, cause acute respiratory distress syndrome (ARDS) and multiple organ failure, and finally lead to death in severe cases of COVID-19 infection. Therefore, inhibiting cytokine storm can significantly reduce inflammatory injury in lung tissues.
Pyridostigmine (PDG), cholinergic anti-inflammatory pathway (CAP) is a neural mechanism that modulates inflammation through the release of acetylcholine (ACh), resulting in decreased synthesis of inflammatory cytokines such as TNF-α and IL-1. This finding emphasis, the nervous and immune systems work collaboratively during infection and inflammation.
Implications of the hypothesis: Administrations of Pyridostigmine (PDG) as cholinergic agonist inhibits the inflammatory response and lower the mortality of COVID-19 patients. Likewise, activation of the CAP during systemic inflammation down-regulates the production and release of inflammatory cytokines.
The infectivity and pathogenesis: SARS-CoV-2, the causative agent of Covid-19, involves Angiotensin-converting enzyme 2 (ACE2) receptors on type II alveolar type 2 (AT2) cells in lungs. Apart from, the upper and lower respiratory tracts, the disease affects the gastrointestinal system prominently, as evidenced by the significant GI symptoms, early in the course of the disease. In addition, the virus infects ACE2-bearing cells in other organs including the heart and blood vessels, brain, and kidneys.
Clinical features and morbidity: The clinical spectrum of COVID-19 varies from asymptomatic or pauci-symptomatic presentation to moderate to severe states characterized by respiratory failure necessitating mechanical ventilation and ICU support and those manifesting critical clinical condition with complications like sepsis, septic shock, and multiple organ dysfunction failure. The CT chest is an important tool for early identification of COVID-19 pneumonia as well as for prognostic purposes.
The recovery and residual damage: The recovery and other outcomes vary depending on age and other aspects including sex, comorbidities, and genetic factors. The outlook for older adults, who account for a disproportionate share of critical disease, is unfavorable, and most of those who survive are unlikely to return to their previous level of functioning. The disease affects their long-term health and quality of life as well as brings in propensity for truncated post-disease survival.
COVID-19 aftermath and follow up: The patients discharged from hospital following severe COVID-19, continue to suffer with lingering impact of the disease as well as that of the emergency treatments that saved their life. The post-infection reduced exercise tolerance and other subtle factors, like post viral fatigue syndrome, post-traumatic stress disorder, impaired concentration, delirium, and disturbed sleep-wake cycle often underly the functional impairment. In fact, there is need of step-down care and later a multidisciplinary support involving regular clinical assessment, respiratory review, physiotherapy, nutritional advice, and psychiatric support.
Conclusion: The life after COVID-19: After recovery from the disease, the virus SARS-CoV-2, may persist for uncertain period. In addition, the chance of reinfection cannot be ruled out. The vitamin D supplementation may be helpful. In general, the quality of life (QOL) in ICU survivors improves but remains lower than general population levels, but most of the patients adapt well to their level of self-sufficiency and QOL. Also, the debility due to co-morbidities may further compromise the activity of daily living and QOL issues. The Age and severity of illness appear to be the major predictors of post-discharge physical functioning.
Background: Azithromycin (AZM) is a macrolide antibiotic with distinct pharmacokinetic properties and is increasingly used as maintenance treatment in patients with bronchiectasis in order to reduce infectious exacerbations and improve pulmonary symptoms. The exact mechanism of action is not known and the relation between azithromycin dose level, local and systemic drug levels and clinical effect however, has not been extensively studied yet.
Objectives: To explore the relation between AZM serum and sputum concentrations, clinical effect parameters and side effects.
Methods: Azithromycin concentrations were measured in serum and sputum samples of bronchiectasis patients receiving one year of AZM treatment (250mg OD) enrolled in the Bronchiectasis and Azithromycin Treatment (BAT) trial, a double blind, randomised placebo-controlled trial. Results were correlated with data on AZM dose level, exacerbation frequency, lung function (forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), quality of life and symptoms collected within the same year.
Results: 83 sputum samples from 31 patients and 151 serum samples from 43 patients were available for analysis. Mean AZM dose-level ranged from 18.8 to 39.8 mg/kg body weight/ week, generating mean AZM concentrations of 7.57 mg/L (SD 9.49) in sputum and 0.11 mg/L (SD 0.085) in serum. No correlation was found between side effects and AZM dose level, sputum- or serum concentrations. Significant correlation was found between AZM sputum concentration and CRP-level (r= -0.6).
Conclusion: High and stable AZM sputum levels were reached during long term treatment, as opposed to low AZM levels in serum. Apart from CRP-levels to AZM sputum concentration, no other outcome parameter showed significant correlation to AZM serum- or sputum levels. AZM dose- or exposure levels were not predictive for the occurrence of side effects.
This is the case of a full-term baby girl, born to a mother with a history of parenteral inorganic mercury administration. Thirteen years prior, this mother injected 1mL of inorganic mercury in her right forearm, was subsequently hospitalized, but never received chelation treatment. Her first trimester blood and urine mercury concentration were found to be elevated at 28μg/L (normal <10μg/L) and 162 μg/L (normal <20μg/L) respectively. Her chest x-ray also revealed multiple small punctate metallic densities within the lower lung fields. The remainder of the prenatal course was uneventful. The baby was born at 40 weeks of gestation via uncomplicated caesarian section, and on day of life 3, blood mercury concentrations were found to be 20μg/L (normal <20μg/L). The baby, however, remained asymptomatic throughout her hospital stay and on outpatient follow up. She is now two years old. Mercury poisoning in the pediatric population remains a concern, and knowledge of exposure and health effects continues to be relevant as newer uses and modes of exposure are discovered. This case report illustrates a rare perinatal exposure scenario, and, while the mother and child were essentially asymptomatic, the case serves to raise awareness of the many ways in which fetuses, infants, and children may still be exposed to the harmful effects of mercury. This case underscores the need for careful environmental history taking in pregnancy, after birth, and ideally in the pre-conception period as well.
As per report of WHO [1] (World Health Organization), air pollution (ambient/outdoor and household/indoor air pollution) kills an estimated seven million people worldwide every year largely as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections. Data of WHO shows that 9 out of 10 people breathe air containing high levels of pollutants. World Health Organization is working with countries to monitor air pollution and improve air quality. From smog hanging over cities to smoke inside the home, air pollution poses a major threat to health and climate. More than 80% of people living in urban areas and around 91% of the world’s population live in places where air quality levels exceed WHO limits, with developing and under-developed countries suffering from the highest exposures, both indoors and outdoors [1]. While outdoor air pollution comes from the motor vehicles, burning of fossil fuels and other industrialization activities, indoor air pollution is the result of tobacco smoke and burning fuel for cooking & heating. Furniture and construction materials also emit such pollutants. Both outdoor and indoor air pollution are harmful to the human health.
Juvenile xanthogranuloma (JXG) is a rare form of non-Langherans cell histiocytosis (non-LCH) observed almost exclusively in infants and young children. It is rarely systemic, involving extracutaneous sites, such as the liver, lungs, spleen, kidney, pancreas, bone or central nervous system. Systemic JXG may be associated with significant complications requiring aggressive medical or surgery care; especially, central nervous system lesions are difficult to treat and reported to be possibly fatal. Clinical presentation of JXG of central nervous system is not specific and is related to the involved site while magnetic resonance imaging examination remains the first choice for localizing the lesions. If no other system is involved, surgical excision could be sufficient.
A term neonate was transferred from a Local Neonatal Unit to our surgical Neonatal Intensive Care Unit on Day 2 due to abdominal distension with radiological appearances suggestive of intestinal obstruction. He was born by Caesarean section with no risk factors for sepsis. He was intubated at birth for increased work of breathing and failed planned extubation on Day 1.
In this manuscript it has been described a novel synthesis of mercury doped hydroxyapatite (Hap) and its application on human liver carcinoma cell line (Hep G2) and human lung fibroblast carcinoma cell line (MRC 5). Nano-sized hydroxyapatite doped with Hg2+ was synthesized by a solution based chemical method along with mercury ion. The surface of nanoparticle of mercury doped hydroxyapatite (MHAp) was functionalized by using phosphonomethyl iminodiacetic acid (PMIDA) for making it stable as dispersed phase with negative zeta potential. Surface functionalization was confirmed by FTIR measurements. Crystalline nature, morphology and surface topology were studied by powder XRD, FESEM and AFM measurements. Particle size of the well dispersed sample was obtained by HRTEM image. The studies on cell viability of Hep G2 and MRC 5 cell in presence of mercury doped HAp nanoparticle (MHAp) were determined through WST assay. It was observed that nanocomposite exhibited a site specific action towards MRC 5 cell lines along with reduction of toxicity toward normal cells.
Introduction: Pneumonia, defined as infection of lung parenchyma, is associated with severe complications especially in the very young and old patients. It is the world’s leading cause of childhood mortality. The World Health Organization (WHO) classification and guidelines are commonly used in Sudan in the diagnosis and management of pneumonia patients. This review was the outcome of some researches done in Sudan by the author and his colleagues. Management Systems were evaluated to give complete end to end solutions for serving patients along with their records in hospitals and clinics in Sudan. The objective of the study was: To reflect author experience in management of childhood pneumonia in Sudan and to determine feasible, affordable approach to pneumonia in Sudan.
Methodology: Searching through PubMed for the author publication and review of publication by author in Sudan regarding management of pneumonia.
Conclusion: Simple tests like chest X-ray, high WBC high-reactive protein, together with high temperature can predict the need for urgent blood culture. Antibiotic treatment for childhood pneumonia weather that recommended by WHO, b-lactam inhibitors or 3rd generation cephalosporin has the same outcome.
Purpose: In an aspect of qualitative treatment, this research gathered lung cancer patients’ actual experiences to understand deeply, such as their expectation for treatment results, their difficulties during treatment, and their various requests to their family and medical teams.
Methods: From May to June 2013, semi-structured interviews were conducted with 9 lung cancer patients. Data were collected through a tape-recorded in-depth interview. The analysis of the data was made through the qualitative method.
Results: 124 themes regarding the experience were found. From these 35 concepts, 24 subcategories were emerged. The core category was enduring hardship of the treatment with the hope for full recovery. Six categories included ‘Wishing to be cured but concern about recurrence’, ‘Receiving radiation treatment with pleasure and difficult at the same time’. ‘Being sorry for their family’s full support and trying to stand alone‘, ‘Having confidence in their medical team’, ‘regretting for their old days’, and ‘Wanting to live a long life without illness and pain’.
Conclusion: The results of this study would help oncology nurses to understand the lung cancer patients receiving concurrent chemo-radiotherapy (CCRT) and to develop a quality of life improvement program for physical, psychosocial, and spiritual aspects of nursing.
Zinc induced pediatric preventing respiratory 2019-nCoV is required that supplementation with zinc gluconate 20 mg in Zn deficient children resulted in a nearly twofold reduction of acute lower respiratory infections as well as the time to recovery. Zinc supplementation in children is associated with a reduction in the incidence and prevalence of pneumonia. Preventing 2019-nCoV pneumonia is required that zinc supplementation alone (10 to 20 mg) for more than 3 months significantly reduces in the rate of pneumonia. zinc pediatric intake may be required to be effective range 10~20 mg/d for 2019-CoV prevention, 10~30 mg/d for reduction of COVID-19 bronchitis, and 20~30 mg/d for recovery from COVID-19 pneumonia, in which Zn2+ could bind with viral surface proteins by Zn2+ions-centered tetrahedrally coordination pattern.
On the other hand, for aults, the zinc-homeostatic immune concentration may provide a protective role against the COVID-19 pandemic, likely by improving the host’s resistance against viral infection. 50 mg of zinc per day might provide an additional shield against the COVID-19 pandemic, possibly by increasing the host resistance to viral infection to minimize the burden of the disease. In order to prevent that an outbreak of respiratory sickness caused by a novel coronavirus (COVID-19) has become a serious public threat and disrupted many lives,assessing the efficacy of FDA-approved Zn-ejector drugs such as disulfiram combined with interferon to treat COVID-19 infected patients has been proposed. The key strategies for preventing lung damages include avoiding direct lung infection, altering host-virus interactions, promoting immune responses, diluting virus concentrations in lung tissues by promoting viral migration to the rest of the body, maintaining waste removal balance, protecting heart function and renal function, avoiding other infections, reducing allergic reactions and anti-inflammatory. The interactions had been found on the binding specificity by Zn2+ ions-centered tetrahedral geometric coordination of the inhibitors against 3C and 3C-like proteases. In addition, transient zinc chelation TPEN and EPDTC have been noted as preventing virus replication.
Zinc-induced ROS production in COVID-19 respiratory ailment and pneumonia occurs both in children and adults. In children.
ROS production in zinc (Ⅱ)-immune pediatric patient with COVID-19 bronchitis and pneumonia cannot be elucidated yet. In adults, zinc induced ROS generation in pulmonary COVID-19 infected cells is that alterations of ROS-producing and scavenging pathways that are caused by respiratory viral infections are implicated in inflammation, lung epithelial disruption, and tissue damage, and, in some cases, even pulmonary fibrosis. The involvement of oxidative stress in cell deaths caused during RNA virus infection and ROS production is correlated with host cell death.
Pulmonary embolism (PE) is an age-related disorder which is potentially fatal, but frequently misdiagnosed. However, the true prevalence of pulmonary embolism is unknown. Inaccurate estimates of PE prevalence might, in part, be attributable to underrecognition of atypical presentations of this disorder. If true prevalence is unknown, the positive predictive values of both typical and atypical symptoms and signs of PE will be unreliable. The negative predictive value of those parameters will, likewise, be unreliable. The aim of this review is to make clinicians more aware of atypical manifestations of PE, thereby increasing the likelihood of correct diagnosis and, hence, ascertainment of the true prevalence of PE. The range of atypical manifestations was explored by a literature search, using MEDLINE from 1946 to February 2019, and EMBASE, from 1947 to February 2019, and Pubmed, from February 2014 to February 2019, using the search terms atypical, uncommon, unusual, pulmonary embolism, lung embolism, pulmonary thromboembolism.
This search revealed atypical presenting features such as non pleuritic retrosternal pain, abdominal pain, atypical breathing patterns, pulmonary oedema, Dressler’s syndrome, atypical radiographic manifestations, atypical electrocardiographic features, manifestations associated with oxygen saturation of 95% or more, coexistence of acute myocardial infarction and pulmonary embolism, coexistence of thoracic aortic dissection and pulmonary embolism, neurological manifestations other than stroke, paradoxical embolism, acute venous thrombosis of atypical location, and pulmonary embolism with normal D-dimer levels.
Nucleic acid-based therapy has become an increasingly important strategy for treating a variety of human diseases. In systemic therapy, a therapeutic gene must be delivered efficiently to its target tissues without side effects. To deliver a therapeutic gene such as plasmid DNA (pDNA) or small interfering RNA (siRNA) to target tissues by systemic administration, cationic carriers such as cationic liposomes and polymers have been commonly used as a non-viral vector. However, the binary complex of therapeutic gene and cationic carrier must be stabilized in the blood circulation by avoiding agglutination with blood components, because electrostatic interactions between positively charged complexes and negatively charged erythrocytes can cause agglutination, and the agglutinates contribute to high entrapment of the therapeutic genes in the highly extended lung capillaries. One promising approach for overcoming this problem is modification of the surface of cationic complexes with anionic biodegradable polymers such as hyaluronic acid, chondroitin sulfate, or polyglutamic acid. As another approach, we recently developed a sequential injection method of anionic polymer and cationic liposome/therapeutic gene complex (cationic lipoplex) for delivery of a therapeutic gene into the liver or liver metastasis. In this review, we describe recent advances in the delivery of therapeutic genes by lipid- and polymer-based carrier systems using anionic polymers.
The global virome: The viruses have a global distribution, phylogenetic diversity and host specificity. They are obligate intracellular parasites with single- or double-stranded DNA or RNA genomes, and afflict bacteria, plants, animals and human population. The viral infection begins when surface proteins bind to receptor proteins on the host cell surface, followed by internalisation, replication and lysis. Further, trans-species interactions of viruses with bacteria, small eukaryotes and host are associated with various zoonotic viral diseases and disease progression.
Virome interface and transmission: The cross-species transmission from their natural reservoir, usually mammalian or avian, hosts to infect human-being is a rare probability, but occurs leading to the zoonotic human viral infection. The factors like increased human settlements and encroachments, expanded travel and trade networks, altered wildlife and livestock practices, modernised and mass-farming practices, compromised ecosystems and habitat destruction, and global climate change have impact on the interactions between virome and its hosts and other species and act as drivers of trans-species viral spill-over and human transmission.
Zoonotic viral diseases and epidemics: The zoonotic viruses have caused various deadly pandemics in human history. They can be further characterized as either newly emerging or re-emerging infectious diseases, caused by pathogens that historically have infected the same host species, but continue to appear in new locations or in drug-resistant forms, or reappear after apparent control or elimination. The prevalence of zoonoses underlines importance of the animal–human–ecosystem interface in disease transmission. The present COVID-19 infection has certain distinct features which suppress the host immune response and promote the disease potential.
Treatment for epidemics like covid-19: It appears that certain nutraceuticals may provide relief in clinical symptoms to patients infected with encapsulated RNA viruses such as influenza and coronavirus. These nutraceuticals appear to reduce the inflammation in the lungs and help to boost type 1 interferon response to these viral infections. The human intestinal microbiota acting in tandem with the host’s defence and immune system, is vital for homeostasis and preservation of health. The integrity and balanced activity of the gut microbes is responsible for the protection from disease states including viral infections. Certain probiotics may help in improving the sensitivity and effectivity of immune system against viral infections. Currently, antiviral therapy is available only for a limited number of zoonotic viral infections. Because viruses are intracellular parasites, antiviral drugs are not able to deactivate or destroy the virus but can reduce the viral load by inhibiting replication and facilitating the host’s innate immune mechanisms to neutralize the virus.
Conclusion: Lessons from recent viral epidemics - Considering that certain nutraceuticals have demonstrated antiviral effects in both clinical and animal studies, further studies are required to establish their therapeutic efficacy. The components of nutraceuticals such as luteolin, apigenin, quercetin and chlorogenic acid may be useful for developing a combo-therapy. The use of probiotics to enhance immunity and immune response against viral infections is a novel possibility. The available antiviral therapy is inefficient in deactivating or destroying the infecting viruses, may help in reducing the viral load by inhibiting replication. The novel efficient antiviral agents are being explored.
Advances in metagenomics have facilitated population studies of associations between microbial compositions and host properties, but strategies to minimize biases in these population analyses are needed. However, the effects of storage conditions, including freezing and preservation buffer, on microbial populations in fecal samples have not been studied sufficiently. In this study, we investigated metagenomic differences between fecal samples stored in different conditions. We collected 46 fecal samples from patients with lung cancer. DNA quality and microbial composition within different storage Methods were compared throughout 16S rRNA sequencing and post analysis. DNA quality and sequencing results for two storage conditions (freezing and preservation in buffer) did not differ significantly, whereas microbial information was better preserved in buffer than by freezing. In a metagenomic analysis, we observed that the microbial compositional distance was small within the same storage condition. Taxonomic annotation revealed that many microbes differed in abundance between frozen and buffer-preserved feces. In particular, the abundances of Firmicutes and Bacteroidetes varied depending on storage conditions. Microbes belonging to these phyla differed, resulting in biases in population metagenomic analysis. We suggest that a unified storage Methods is requisite for accurate population metagenomic studies.
Systemic arterial air embolism (SAAE) is a rare but serious complication of CT-guided hook wire localization of pulmonary nodule usually with catastrophic and poor outcome. Hook wire needle localization is done pre-operatively by placing wire around or into the pulmonary nodule to provide the thoracic surgeon accurate location guidance of the target nodule for Video-Assisted Thoracoscopic Surgery (VATS) wedge resection with safety margins. Physicians should be aware of this possible complication during the procedure in order to rescue the patient promptly as it requires rapid diagnosis and management. We describe a 55-year-old male who underwent a CT-guided hook wire needle localization of left upper lobe lung cancer and left lower lobe pulmonary nodule prior to planned VATS wedge resection who developed altered mental status and bilateral lower extremities paralysis after wire placement was completed. His CT head demonstrated small air embolism in the left occipital area, confirming the diagnosis of cerebral air embolism and follow up CT and MRI of the head revealed multiple areas of brain infarction. In addition, he was diagnosed with anterior spinal cord syndrome (ACS), most likely due to anterior spinal artery ischemia from micro air embolism on the basis of clinical findings but with negative ischemic changes on MRI of the spinal cord. His mental status recovered but he remained paraplegic and transferred to inpatient rehabilitation service.
The objective was to assess the antioxidant effect of melatonin (MLT) on liver and lung tissues of animals with bile duct ligation (BDL)-induced hepato-pulmonary syndrome (HPS). A model of BDL-induced biliary cirrhosis was used in male Wistar rats. Results suggest that MLT has an antioxidant effect on liver and lung tissues in animals with BDL-induced HPS by higher activity of antioxidant enzymes in the group HPS treated with MLT and the histological analysis of lung parenchyma showing decreased damage in this same group, including other analysis described below.
The SARS-Cov-2 virus was firstly identified in Wuhan, China and caused catastrophic destruction all over the world. COVID-19 virus primarily effects lungs of its hosts and impairs it in number of ways. It can also damage multiple organs like Heart, kidney, endocrine glands, skin, brain and several others. Kidneys are also damaged to a great extent. In Heart it can cause acute coronary syndrome, Heart failure, Myocardial infarction. SARS-CoV-2 effect brain especially psychologically. It also causes serious lymphocyte apoptosis. It also neutralizes human spleen and lymph nodes. SARS-CoC-2 can be harmful for those having already liver diseases. Similarly, SARS-CoV-2 has a direct impact on endocrine glands. It is responsible for the various injurious changes in hormones, causes various diseases like acute pancreatitis, decrease in GH, hypoparathyroidism etc. and lead to cause tissues damage in glands. It also some minor effects on nose, and respiratory pathways. It also has some minor effects on eyes and ears whereas it causes several devastations in GIT.
Pneumomediastinum is the presence of free air within the mediastinum. As a general rule, it occurs in the presence of underlying lung disease and if it does not exist, it is called spontaneous pneumomediastinum. We present a case of a 53 years old asthmatic patient which further investigation revealed to be consistent with spontaneous pneumomediastinum. He underwent medical treatment with relative rest, oxygen therapy, and prophylactic antibiotic therapy, in addition to his usual asthma treatment. There was a clinical and radiological improvement with complete passive reabsorption of air and the patient was discharged on the 4th day and referred to the pulmonology department for consultation. During 2 months follow-up period, there were no signs of recurrence.
In pregnancy, the incidence of pulmonary embolism (PE) is increased fivefold when compared to nonpregnant women of the same age, and PE is one of the leading causes of death during pregnancy.However, the diagnosis of PE among pregnant women is complicated by concerns regarding radiation exposure. Systemic lupus erythematosus (SLE) is an autoimmune disorder with a wide array of presentations and a predilection to affect women of certain ethnic backgrounds. The hallmark of the disease is multisystem involvement, dispersed in time and severity. Usual pulmonary involvement includes pleuritis, pleural effusions, pneumonitis, shrinking lung syndrome, pulmonary hypertension, and alveolar hemorrhage. Pulmonary embolism (PE) is a relatively unusual presentation of SLE. We report the case of a 20-year-old primi at 21 weeks gestation with an acute PE with central chest pain and shortness of breath. The absence of overt signs and symptoms and traditional risk factors prompted a fragmentary workup. This led to the detection of antibodies sensitive for SLE, in the absence of overt signs and symptoms. We revive the concept of latent lupus, a condition construed as early lupus. We firmly suspect direct causation between SLE and PE. Further studies are needed to establish pathogenesis to facilitate early diagnosis and prevent morbidity and mortality from PE. Due to persistent hypotension, thrombolytic therapy with streptokinase was administered and the clinical and hemodynamic response was excellent, with no maternal or fetal hemorrhagic complications. The clinical presentation of pulmonary embolism is sometimes camouflaged by the physiological changes that occur in pregnancy and diagnosis is often delayed by a reluctance to expose the fetus to ionizing radiation.
