RESUMO

Disease is defined as complex interaction of 3 things: disease-causing agent, host and environment. The government, CDC and hospital administrations have had reasonable success with the effects of social distancing and coronavirus testing; kudos to them. That addresses 1 of the 3 main factors of a disease; i.e. disease -causing agent. However, there are 2 other ingredients in the complex of a disease; i.e. the host of the disease and finally the environment of the disease. We are the hosts and it is time we take ownership of this ourselves and join the effort with the government towards understanding the dysregulated immune response seen in severe covid-19 and enable the public in strengthening the inner environment and the host immune response. Social distancing can be complete only when the host is prepared to fight the war in the coming fall and winter seasons. The outer environment seems to spontaneously recharging itself as a consequence of social distancing.

RESUMO

Acquired thrombotic thrombocytopenic purpura (aTTP) is a serious disorder with arteriolar and capillary thrombosis for which the treatment usually requires plasma exchange with plasma as the replacement fluid. Management of patients who do not accept blood products is a serious challenge. We present the case of a Jehovah's Witness patient who achieved clinical response after treatment with plasma exchange using human albumin solution as the replacing fluid, high dose corticosteroids, and rituximab. The patient also received ADAMTS13 containing plasma cryoprecipitate and von Willebrand factor VIII concentrates. She had an exacerbation of her TTP in less than 3 weeks. She was treated with further plasma exchange with human albumin solution as the replacement fluid, high dose steroids, and rituximab. Bortezomib and N-acetylcysteine were added. The patient eventually improved clinically and achieved remission that is ongoing for more than 7 months. A review of the literature shows that all five previously reported cases of aTTP in Jehovah's Witnesses survived although none received plasma. Two were not even treated with plasma exchange. The experience of this case and those in the literature demonstrates that remission of aTTP may be achieved without using plasma or plasma exchange.

RESUMO

BACKGROUND: Antibiotics are often prescribed for hospitalized patients with chronic obstructive pulmonary disease (COPD) exacerbations. The use of procalcitonin (PCT) in the management of pneumonia has safely reduced antibiotic durations, but limited data on the impact of PCT guidance on the management of COPD exacerbations remain. OBJECTIVE: To determine the impact of PCT guidance on antibiotic utilization for hospitalized adults with exacerbations of COPD. DESIGN: A retrospective, pre-/post-intervention cohort study was conducted to compare the management of patients admitted with COPD exacerbations before and after implementation of PCT guidance. The pre-intervention period was March 1, 2014, through October 31, 2014, and the post-intervention period was March 1, 2015, through October 31, 2015. PARTICIPANTS: All patients with hospital admissions during the pre- and post-intervention period with COPD exacerbations were included. Patients with concomitant pneumonia were excluded. INTERVENTION: Availability of PCT laboratory values in tandem with a PCT guidance algorithm and education. MAIN MEASURES: The primary outcome was duration of antibiotic therapy for COPD. Secondary objectives included duration of inpatient length of stay (LOS) and 30-day readmission rates. KEY RESULTS: There were a total of 166 and 139 patients in the pre- and post-intervention cohorts, respectively. There were no differences in mean age (66.2 vs. 65.9; P = 0.82) or use of home oxygenation (34% vs. 39%; P = 0.42) in the pre- and post-intervention groups, respectively. PCT guidance was associated with a reduced number of antibiotic days (5.3 vs. 3.0; p = 0.01) and inpatient LOS (4.1 days vs. 2.9 days; P = 0.01). Respiratory-related 30-day readmission rates were unaffected (10.8% vs. 9.4%; P = 0.25). CONCLUSIONS: Utilizing PCT guidance in the management of COPD exacerbations was associated with a decreased total duration of antibiotic therapy and hospital LOS without negatively impacting hospital readmissions.

RESUMO

BACKGROUND: Community-acquired pneumonia and healthcare-associated pneumonia are often treated with prolonged antibiotic therapy. Procalcitonin (PCT) has effectively and safely reduced antibiotic use for pneumonia in controlled studies. However, limited data exist regarding PCT guidance in real-world settings for management of pneumonia. METHODS: A retrospective, preintervention/postintervention study was conducted to compare management for patients admitted with pneumonia before and after implementation of PCT guidance at 2 teaching hospitals in Pittsburgh, Pennsylvania. The preintervention period was March 1, 2014 through October 31, 2014, and the postintervention period was March, 1 2015 through October 31, 2015. RESULTS: A total of 152 and 232 patients were included in the preintervention and postintervention cohorts, respectively. When compared with the preintervention group, mean duration of therapy decreased (9.9 vs 6.0 days; P < .001). More patients received an appropriate duration of 7 days or less (26.9% vs 66.4%; P < .001). Additionally, mean hospital length of stay decreased in the postintervention group (4.9 vs 3.5 days; P = .006). Pneumonia-related 30-day readmission rates (7.2% vs 4.3%; P = .26) were unaffected. In the postintervention group, patients with PCT levels <0.25 µg/L received shorter mean duration of therapy compared with patients with levels >0.25 µg/L (4.6 vs 8.0 days; P < .001), as well as reduced hospital length of stay (3.2 vs 3.9 days; P = .02). CONCLUSIONS: In this real-world study, PCT guidance led to shorter durations of total antibiotic therapy and abridged inpatient length of stay without affecting hospital readmissions.

RESUMO

Clostridium perfringes is a gram-positive, rod-shaped, anerobic, spore-forming pathogenic bacterium. C. perfringes is commonly known to cause tissue necrosis and gas gangrene. However, severe life-threatening complications like hemolysis due to clostridium sepsis are rarely encountered. We present a case of a 35-year-old female presenting with endometritis complicated with severe hemolysis in the setting of sepsis secondary to C. perfringes. Her hospital course was complicated with multi-organ involvement, requiring broad-spectrum intravenous antibiotics. Eventually, she made an uneventful recovery by early recognition of these rare complications and prompt institution of appropriate therapy.

RESUMO

A woman aged 22 years with a history of lupus presented in the 18th week of pregnancy with hypertensive emergency and flash pulmonary oedema. Bedside echocardiogram revealed severe left ventricular (LV) dysfunction with an ejection fraction (EF) of 25% and pericardial effusion. Laboratories revealed hypocomplementemia, proteinuria, elevated C reactive protein and anti-DS-DNA, raising concern for a lupus flare. Cardiac MRI showed an acute intramyocardial oedematous process, consistent with lupus carditis, and further worsening of LVEF to 13%. Shared-decision-making with the patient included discussion of maternal risks of continuation of pregnancy in the setting of worsening heart function and the fetal risks of definitive treatment with cyclophosphamide for a lupus flare and the patient decided to proceed with medical termination of pregnancy. Treatment with immunosuppressants, including cyclophosphamide, and steroids, was then initiated. 2 months after discharge, cardiac MRI showed marked improvement in LVEF to 50% and the patient remains clinically free of heart failure.

RESUMO

A 62-year-old African-American man admitted to the emergency room with chest pain and exertional dyspnoea. He was found to be in rapid atrial fibrillation with pulmonary oedema. A transoesophageal echocardiogram performed prior to cardioversion showed a depressed left ventricular function (ejection fraction 30%) and an extracardiac heterogeneous echodensity compressing the right atrium and the superior vena cava. CT of the chest confirmed an anterior mediastinal mass measuring 13.5×6.6×10.1 cm, exerting a mass effect on the right atrium with mediastinal and right hilar adenopathy. CT-guided biopsy of the mediastinal mass revealed thymic carcinoma (squamous cell subtype). The metastatic workup was negative. The mass was deemed surgically unresectable due to its proximity to the heart. Chemotherapy was initiated with carboplatin/paclitaxel every 3 weeks with plans for intensity modulated radiotherapy after one to two cycles of chemotherapy. The patient recently had a repeat CT scan of the chest showing regression of the tumour.
