A Rare Complication of Leptospirosis: Weil's Disease Diagnosed in the United States

Leptospirosis is mostly found in tropical regions such as Latin America and Southeast Asia. Here we present a case of leptospirosis in the United States in a 43-year-old African American male who had complications such as sepsis, acute renal failure, hyperbilirubinemia, and transaminitis. Through this case report, we want to highlight the rare occurrence of this infection in the United States. It should be considered high in the list of differential diagnoses for patients traveling to underdeveloped countries and participating in adventure sports. Early recognition and treatment of leptospirosis are essential in decreasing life-threatening complications.

An Atypical Presentation of a Pyogenic Liver Abscess Caused by Fusobacterium nucleatum Post-ruptured Appendix

A rare formation of a pyogenic liver abscess can be found in patients with a ruptured appendix. Here, we discuss a 49-year-old male with a past medical history significant for drug-induced pancreatitis from metformin, type II diabetes, obesity, and hypertension who presented with right upper quadrant pain. He was diagnosed with a 12.6 cm pyogenic liver abscess. Upon further chart review, the patient had a laparoscopic appendectomy done nine months ago, with the findings of a ruptured appendix. The liver abscess cultures grewFusobacterium nucleatum - a common culprit of acute appendicitis reported in several case studies and clinical trials. This case report highlights the importance of including appendectomy as an essential part of history-taking and diagnostic differential for pyogenic liver abscesses.

Clinical outcomes and adverse drug reactions in COVID-19 patients treated with hydroxychloroquine and azithromycin alone or combined

Background. Use of Hydroxychloroquine with or without Azithromycin is repurposed in SARS-CoV-2 in the absence of definitive treatment. Objective. To evaluate the association between the use of Hydroxychloroquine and Azithromycin when given alone or in combination on clinical outcomes and adverse drug reactions among lab confirmed SARS CoV-2 positive patients admitted in a COVID tertiary care hospital of a University Medical college. Methods. a retrospective observational comparative study was conducted. COVID-19 positive patients admitted in study hospital for management of COVID-19 were enrolled into the study. The patients were categorized into 4 treatment groups based on having received the following treatment during hospitalization: (A) Hydroxychloroquine with Azithromycin, (B) Hydroxychloroquine without Azithromycin (Hydroxychloroquine alone), (C) Azithromycin alone, and (D) Neither drug, defined as no receipt of either Hydroxychloroquine or Azithromycin in the record; other medications may have been dispensed. Results. 800 patients were enrolled. Mean±Standard deviation of duration of hospital stay (in days) for study Group A was 11.37±7.11, for Group B was 8.37±4.77, for Group C was 18.22 ± 5.69 and for Group D was 6.12±2.97. Mortality in Group A was 29.74%, Group B – 33.16%, Group C – 0% and in Group D – 1.32%. Conclusion. Among hospitalized patients with COVID-19 treatment, Group C was associated with good clinical outcome. However, the interpretation of these findings may be limited by the observational design.

A BRIEF SYNOPSIS OF MONOCLONAL ANTIBODY FOR THE TREATMENT OF VARIOUS GROUPS OF DISEASES

Monoclonal antibodies (mAbs) are increasingly being prescribed to patients and investigated in the field of medicine and research. This class of medication is unique due to its ability to be engineered into targeting a specific receptor. Numerous studies and reviews have reported the efficacy, potency, and clinical usage of mAbs in the treatment of a variety of diseases ranging from autoimmune disorders to malignant cancers. However, very few publications classify and provide a brief synopsis of mAbs that includes their pharmacological profiles. mechanisms of action, uses, and side effects in a concise manner. Therefore, this review aims to classify the current mAbs drugs used in clinical practice according to system diseases by providing a brief summary for each of them. For example, regarding cardiovascular disorders, mAbs such as Abciximab, Bevacizumab, and Digoxin Immune Fab will be reviewed. Denosumab, used to treat musculoskeletal disorders, will be also discussed. In addition, mAbs such as Adalimumab, Eculizumab, Natalizumab used in autoimmune disorders and Alemtuzumab, Trastuzumab, Cetuximab, and Rituximab that are prescribed for tumors will be reviewed. Finally, we shall discuss two mAbs that are IL-6 antagonists, Tocilizumab and Siltuximab, which are in ongoing clinical trials as potential treatments of COVID-19. The mAbs have profound benefits against chronic and malignant conditions, and the overall purpose of this review is to illustrate the basic pharmacological profiles of mAbs that physicians may find useful in establishing their management protocols.

Quality of life and well-being of population at the end of third phase of lockdown in india against the COVID-19 pandemic

Background. On March 24, 2020, a nationwide Lockdown for 21 days was ordered by the Government of India which was then extended till May 31, 2020. Researchers have predicted lockdown is a necessary step to prevent COVID-19 spread. However, others have also stated that it could cause serious damage to the economic, mental, social, and physical well-being of the people. Objective. The aim of the study is to evaluate the impact of lockdown on the quality of life and well-being of the Indians. Methods. It is a cross sectional prospective web-based questionnaire study. A link (https://forms.gle/pX25VuahP5NxT88QA) was created. Total 426 responses were received via that link and the data was included in the statistical analysis. Results. Our study revealed that during the lockdown 61.5% of the respondents were performing physical activities lesser than before. More than half responded they had a reduced financial satisfaction. Most answers on emotional well-being and social-family wellbeing were also positive, but some responses showed disturbing too, like 22% felt anxious and nervous over half of the days. It was found in the study that physical, financial, emotional, mental, social and family wellbeing were disturbed during the lockdown and quality of life was also hampered. Conclusion. Though, may be Nationwide Lockdown was the most required action at that point of time to prevent virus spread, but our study revealed that uncertainty regarding its cure and management guidelines like lockdown and social distancing has badly affected quality of life and wellbeing of the population.

Pharmacological activation of peroxisome proliferator-activated receptor γ (PPAR-γ) protects against hypoxia-associated fetal growth restriction

The hypoxia of high-altitude (HA) residence increases the risk of intrauterine growth restriction (IUGR) and preeclampsia 3-fold, augmenting perinatal morbidity and mortality and the risk for childhood and adult disease. Currently, no effective therapies exist to prevent these vascular disorders of pregnancy. The peroxisome proliferator-activated receptor γ (PPAR-γ) is an important regulator of uteroplacental vascular development and function and has been implicated in the pathogenesis of IUGR and preeclampsia. Here, we used a model of HA pregnancy in mice to determine whether hypoxia-induced fetal growth restriction reduces placental PPAR-γ protein expression and placental vascularization and, if so, to evaluate the effectiveness of the selective PPAR-γ agonist pioglitazone (PIO) for preventing hypoxia-induced IUGR. Hypoxia resulted in asymmetric IUGR, placental insufficiency, and reduced placental PPAR-γ expression; PIO prevented approximately half of the fetal growth restriction and attenuated placental insufficiency. PIO did not affect fetal growth under normoxia. Although PIO was beneficial for fetal growth, PIO treatment reduced placental vascular density of the labrynthine zone in normoxic and hypoxic (Hx) conditions, and mean vascular area was reduced in the Hx group. Our results suggest that pharmacological PPAR-γ activation is a potential strategy for preventing IUGR in pregnancies complicated by hypoxia, although further studies are needed to identify its likely metabolic or vascular mechanisms.-Lane, S.
