Guselkumab-Associated Pulmonary Disease and Diffuse Alveolar Hemorrhage with Drug Rash with Eosinophilia and Systemic Symptoms.

Psoriasis is a common skin condition worldwide. Moderate-to-severe disease is treated with biologic or non-biologic disease-modifying anti-rheumatic drugs. These include tumor necrosis factor (TNF)-a inhibitors, interleukin (IL)-17 inhibitors, and IL-23 inhibitors. Case reports of inhibitors of TNF-a and IL-12p40 subunits causing interstitial pneumonia (IP) have been published in the literature, but no case of anti-IL-23p19 subunit biologics causing IP and acute respiratory distress syndrome (ARDS) has been reported before. We report a case of a patient with restrictive lung disease secondary to a body mass index of 36.54 kg/m2, obstructive sleep apnea, and psoriasis, who developed IP and ARDS presumed to be secondary to guselkumab, an anti-IL-23p19 subunit monoclonal antibody. He was on ustekinumab, an anti-IL-12/23p40 for the treatment of psoriasis, but was switched to guselkumab eight months before the presentation, and since then he had been complaining of progressive shortness of breath. He initially presented to the hospital after having drug reaction with eosinophilia and systemic symptoms (DRESS) after being started on amoxicillin for a tooth infection. He was treated with high-dose intravenous steroids but developed progressive shortness of breath. Broad-spectrum antibiotics were added. An extensive infectious, autoimmune, and hypersensitivity work-up was undertaken, which returned negative. A bronchoscopy with bronchoalveolar lavage was performed, which revealed diffuse alveolar hemorrhage (DAH). His lung imaging and oxygenation progressively got worse; hence, no lung biopsy was taken. He was intubated and required inhaled nitric oxide, but due to the lack of improvement, the family elected for comfort measures, and the patient was extubated and passed away. To our knowledge, this is the first case of an association between guselkumab, IP, ARDS, and DAH. Rare instances of DAH with DRESS have been reported before. Whether it was DRESS or guselkumab that caused DAH was uncertain in our patient. Clinicians should monitor for DAH and shortness of breath in patients on guselkumab so that more data can be obtained and studied in the future.

Niacin-Induced Syncope in a Middle-Aged Male: When an Over-the-Counter Vitamin Goes Wrong.

Niacin is an essential vitamin with lipid-modifying properties. It is readily available in many over-the-counter (OTC) supplements. However, the use of niacin can lead to undesirable adverse reactions, including flushing, nausea, hyperglycemia, etc. Here, we present a rare case of niacin-induced syncope caused by a sudden increase in dosage in a middle-aged male. Extensive history, examination, and cardiovascular investigation were obtained to rule out various common etiologies of syncope. We also discuss the utility of niacin as a nutritional supplement, as most individuals obtain sufficient niacin intake from foods and beverages. As a treatment for dyslipidemia, niacin no longer exhibits cardiovascular benefits in the contemporary statin era. We argue that an additional niacin supplement is both unnecessary and potentially harmful. Therefore, niacin supplementation should be cautiously taken with no additional health benefits and frequent deleterious effects.

Acute Respiratory Distress Syndrome Secondary to Enterovirus-Human-Rhinovirus Infection in an Adult.

Enterovirus-human-rhinovirus (EV-HRV) are small RNA viruses that are airborne and can spread by direct contact or fomites and usually cause the common cold, asthma and chronic obstructive pulmonary disease exacerbation. EV-HRV-associated acute respiratory distress syndrome (ARDS) is common in children but is a rare cause of ARDS in adults. ARDS is defined according to the Berlin criteria and can be mild, moderate or severe depending on the PaO 2 to FiO2 ratio. We report a case of a 70-year-old female with cardiac comorbidities, emphysema, second-hand smoking of 25 years, on methotrexate for rheumatoid arthritis presenting with ARDS secondary to EV-HRV infection. Despite initial treatment with appropriate antibiotics, steroids, low tidal volume mechanical ventilation, rescue maneuvers such as ventilation in prone positioning, paralyses, and inhaled nitric oxide, she passed away. EV-HRV causes upper respiratory tract infections but causes cytokine releases such as IL-1, IL-6, and IL-8 in the lower respiratory tract and in the blood which can cause ARDS. Very few cases of EV-HRV ARDS in immunocompetent adults are reported in the literature. Female sex is also associated with EV-HRV ARDS. No antiviral therapy exists for patients critically ill with EV-HRV; however, one case of successful treatment with high-dose intravenous vitamin C (HIVC) is reported in the literature. EV-HRV is one of the most common viruses identified in patients admitted with viral pneumonia in the intensive care unit. It should not be forgotten as a cause of ARDS.

Right Atrial Thrombus Presenting as Platypnea-Orthodeoxia Secondary to Reverse Lutembacher Syndrome: A Case Report.

Platypnea-orthodeoxia syndrome (POS) is defined by dyspnea and deoxygenation due to a change in body position from lying down to an upright position. We present a case of a large right atrial (RA) thrombus likely due to a right coronary artery fistula in a patient with a patent foramen ovale (PFO). On imaging, the thrombus was thought to be an atrial myxoma involving the tricuspid valve; however, after surgical excision and histopathological analysis, it was noted to be a cystic thrombus. Red-brown material along with vascular elements was noted on histopathology. Post-surgery, the patient was critically ill and died due to severe tricuspid regurgitation (TR) and hypotension despite using a right ventricle assist device and multiple vasopressors. Reverse Lutembacher syndrome (RLS) is defined as a triad of tricuspid stenosis (TS), elevated RA pressure, and right-to-left atrial shunting. The location of the mass and positional changes could be causing transient RLS from positional TS and interatrial shunting via the PFO causing POS. Cardiac magnetic resonance imaging can help differentiate between intracardiac masses. T1 and T2 signal characteristics and differences in contrast enhancement can help differentiate between a thrombus and a tumor. Treatment options include anticoagulation, thrombolysis, and thrombectomy. If severe TR occurs after surgery, treatment modalities such as caval valves could be an option in the future. Extracorporeal membrane oxygenation to provide right ventricle support in such cases could be considered.

Concealed Foreign Body Shrouding Airway Mimicking Mass Causing Extubation Failure, Hypoxia, and Stridor.

Foreign body (FB) aspiration can present with acute life-threatening asphyxiation to recurrent infections with lung damage. Although most esophageal FBs pass spontaneously, sharp ones can get embedded requiring treatment. Tracheobronchial FBs and hypopharyngeal FBs are occasionally seen as well. We present a case of an oropharyngeal FB presenting with signs of stroke, pulmonary embolism, pulseless, and causing airway compression and extubation failure. Old age and neurocognitive disability are important predisposing factors of FB airway obstruction (FBAO), with food being the most common cause. The classic triad of cough, dyspnea, and cyanosis is seen in only a small percentage of patients with FBAO. Laryngeal edema, soft tissue collapse, and laryngospasm are among the common causes of upper airway obstruction and extubation failure. Laryngeal traumatism that can occur during emergency intubations can cause post-extubation stridor that can be treated with corticosteroids. Dentures and blood have been reported to cause post-extubation complications but oropharyngeal FB causing airway compression and leading to extubation failure has not been reported before. We recommend FB to be considered in the differential diagnosis of immediate hypoxia and extubation failure regardless of the history of a witnessed aspiration event as it is an easily fixable cause and can be missed in the initial history of presentation. A high degree of suspicion for this should be maintained as it is easy to miss. Computed tomography of the neck can aid in the diagnosis.

A Unique Case of Community Acquired Proteus mirabilis Meningitis.

Proteus mirabilis, a gram-negative bacterium commonly known for causing urinary tract infections (UTI) can rarely present with central nervous system (CNS) infections. Proteus mirabilis CNS infections are usually encountered in the neonatal and infantile period and occasionally cause brain abscesses. It is an uncommon cause of adult CNS infection. We report the first case of a community-acquired Proteus mirabilis meningitis (PMM) in a patient with Proteus mirabilis UTI, urolithiasis, and bacteremia. Risk factors for gram-negative bacillary meningitis (GNBM) include extremes of age, cancer history, diabetes mellitus, UTI, and nosocomial exposure, with the latter being a more prominent cause of PMM. Compromise of the anatomical defense against CNS infections whether accidental or neurosurgical is another important cause, and approximately two-thirds of reported cases of PMM have occurred after neurosurgical procedures. PMM patients develop fever, altered consciousness, and have an acute clinical course. Antimicrobials that can be used for treatment include third-generation cephalosporins, ciprofloxacin, imipenem/ cilastatin, aztreonam, and intraventricular aminoglycosides. Despite appropriate antibiotic therapy outcomes are poor with severe neurological deficit and death commonly resulting. Nosocomial infections can be drug-resistant and multiple antibiotics should be started while awaiting culture results. Literature review reveals that treatment with intraventricular aminoglycosides when attempted has shown bacteriological cure indicating this can be an important treatment approach. Due to the acute clinical course and high morbidity and mortality, we recommend starting multiple antibiotics with different mechanisms of action as soon as the disease is suspected. Our patient was initially started on ceftriaxone, vancomycin, acyclovir, and ampicillin for UTI and meningoencephalitis. The antibiotics were later consolidated to cefepime based on blood, urine and, cerebrospinal fluid cultures growing pan-sensitive Proteus mirabilis. Her clinical condition continued to worsen and ciprofloxacin was added. However, due to the progressive decline in her condition, the family elected for inpatient hospice care and intraventricular aminoglycosides were not attempted.

A rare case of rectal bleeding and Fusobacterium mortiferum sepsis due to solitary fibrous tumour originating from the mesentery.

Solitary fibrous tumours (SFTs) are rare mesenchymal tumours that are mostly seen in the pleura. Lately, they have also been described in other locations. Recent discovery of the NAB2-STAT6 fusion gene which is specific for SFTs has led to an accurate diagnosis of SFTs. The occurrence of SFTs in the mesentery is very rarely reported in the literature. We report a case of a 63-year-old female who presented with abdominal pain, rectal bleeding and Fusobacterium bacteraemia, who was ultimately found to have a mesenteric SFT.

Hantavirus Cardiopulmonary Syndrome and Diffuse Alveolar Hemorrhage in the Era of COVID-19.

Hantavirus Cardiopulmonary Syndrome (HCPS) can occur after infection with Hantavirus which can occur by inhaling aerosolized rodent urine, feces, and saliva contaminated with the virus. It presents with the rapid development of pulmonary edema, respiratory failure, and cardiogenic shock with the hallmark being microvascular leakage. We report a patient with a history of alcohol abuse and recent exposure to mice and sick kittens who presented with cough with sputum production, shortness of breath, orthopnea, and new-onset lower extremity edema. Imaging revealed bilateral infiltrates more common on the left with an unremarkable echocardiogram. Testing for COVID-19, Human Immunodeficiency Virus (HIV), influenza, bacterial pneumonia including tuberculosis and methicillin-resistant Staphylococcus aureus (MRSA), aspergillosis, histoplasmosis, Blastomyces, and Coccidiodes was negative. Bronchoscopy and bronchoalveolar lavage revealed diffuse alveolar hemorrhage (DAH) and were negative for acid-fast bacilli and Nocardia cultures. He was further tested for Hantavirus, Q fever, leptospirosis, toxoplasmosis, and empiric treatment with doxycycline initiated. His Hantavirus IgM antibody came back positive. Human Hantavirus infection occurs after inhalation of infected rodent excreta; fortunately, human-to-human transmission has not been documented. HCPS most commonly occurs due to the Sin Nombre virus (SNV), has a case fatality rate of 50%, and is a notifiable disease in the United States. It has 3 distinct phases, prodromal, cardiopulmonary, and convalescent/recovery. The cardiopulmonary phase occurs from increased permeability of pulmonary capillaries and in severe cases can progress to cardiogenic shock. Diagnosis is based on the presence of IgM and IgG Hantavirus antibodies. Treatment is mainly supportive; however, patients are usually treated with broad-spectrum antibiotics while workup is underway. In animal models, ribavirin and favipiravir are only effective when administered in the prodromal phase. If suspicion of Hantavirus infection exists, early mobilization to the intensive care unit for treatment is recommended. Extracorporeal membrane oxygenation (ECMO) has been suggested to improve outcomes in severe HCPS with refractory shock.

Association of cigarette smoking with irritable bowel syndrome: A cross-sectional study.

Background: Irritable Bowel Syndrome (IBS) is one of the most commonly diagnosed gastrointestinal disorders, and its etiology is believed to be multifactorial. The role of smoking in the pathophysiology of IBS still remains inconclusive. Hence, we aim to investigate whether or not an association exists between smoking and IBS. Methods: A cross-sectional study was conducted in a tertiary care hospital of Karachi. A sample size of 200 smokers and 200 non smokers was selected. A two-part self-reported questionnaire was administered to the participants and the diagnosis of IBS was based on the Rome III diagnostic criteria. All data were analyzed using the Statistical Package for the Social Sciences version 17. Statistical tests employed were Independent samples t-test, chi-square test, and binary logistic regression analysis to obtain Odds Ratio (OR) for various variables. A P-value <0.05 was considered statistically significant. Results: Overall prevalence of IBS based on Rome III criteria was 9.5% (95% CI 9.45-9.60). Smoking was significantly found to be associated with IBS (P=0.002). Binary logistic regression analysis indicated that non-smokers were more likely to have IBS (Crude OR: 3.00, 95% CI 1.23-7.30) than smokers, and females were more likely to have IBS (Crude OR: 3.73, 95% CI 1.56-7.69) than males. Age, BMI, and food groups were not found to be significantly associated with IBS. Conclusion: Our study concludes that IBS was more prevalent among non-smokers and amongst females. Further studies are required to firmly establish the role of smoking in IBS.

Statins everyday versus alternate days: Is there a difference in myalgia rates?

OBJECTIVE: Statins are widely used drugs, known to cause myalgia, leading to high discontinuation rates. The objective of our study was to determine the frequency of myalgia in patients on everyday-dose (EDD) regimen with those on alternate-day dose (ADD) regimen. METHODS: This cross sectional study was conducted in a tertiary care hospital of Pakistan. A sample size of 400 patients between the age of 40-70 years, taking simvastatin 40mg for at least 6 months or more were selected. Patients with prior musculoskeletal or neuromuscular complains, and family history of muscular disorders were excluded. Subjects were evaluated for myalgia via a self-administered questionnaire, and those complaining of myalgia were then evaluated for serum vitamin D levels. Data was analyzed through SPSS 16.0 and compared using chi square test. RESULTS: The overall prevalence of myalgia was 7% (28/400). Frequency of myalgia in patients taking simvastatin everyday (n=20, 10%) was significantly higher compared to those taking it every alternate day (n=8, 4%) (p=0.02). There was no significant difference between the time of onset, nature, severity, type, or location of myalgia between the 2 groups. The most common cited triggering factor for pain was physical exercise. Of the patients experiencing myalgia, 13 (6.5%) from the EDD group and 6 (3%) from the ADD group had low levels of vitamin D. CONCLUSIONS: ADD regime was better tolerated by the patients than EDD regime. Alternate day therapy, with or without vitamin D supplementation, may be used by the physicians for troublesome muscular complains.

Existing Smog in Lahore, Pakistan: An Alarming Public Health Concern.

Lahore, the second-largest and most polluted city in Pakistan, has been plagued by a heavy blanket of smog recently. The ever-growing urbanization and industrialization have contributed to the worsening air quality of the city. Smog, being hazardous to health, is leading to a rapid sprout in multiple health-related problems, as well as raising concerns about the long-term deleterious effects on public health. The current situation is expected to worsen due to the lack of an active action plan from the government's side and a failure of concerned authorities to take note of the urgency of the situation. Hence, we aim to highlight this pressing issue in the light of previously published articles, to alert the relevant authorities regarding the detrimental consequences smog can have on public health and urge them to take immediate action to avoid further damage.

Predictors of Mortality in Patients Undergoing Mitral Valve Replacement.

OBJECTIVE: Although mitral valve replacement is frequently performed in patients of all age groups, there are few studies available which determine the causes of operative mortality in mitral valve replacement especially in our region. Therefore, the objective of this study was to identify factors that are significantly associated with operative mortality in mitral valve replacement. METHODS: From August 2012 to March 2013, 80 consecutive patients undergoing mitral valve replacement in a single tertiary hospital were included. Patients with a history of previous coronary artery bypass graft surgery or congenital heart problems were excluded from the sample. The included patients were observed for a period of 30 days. Pre and post-operative variables were used to identify significant predictors of mortality. RESULTS: The overall hospital mortality (30 days) was 15%. High post-perative creatinine (P =0.05), high ASO titre (P=0.03), young age (P=0.011), low cardiac output (P=0.0001), small mitral valve size (P=0.002) and new onset of atrial fibrillation (P=0.007) were the significant independent predictors of operative morality. CONCLUSION: Mitral valve replacement can be performed in third world countries with limited resources with low mortality. However, optimal selection of mitral valve size can help to improve operative mortality.
