RESUMO
Self-medication (SM) is characterized by the procurement and use of medicines by bypassing primary healthcare services and without consulting a physician, usually to manage acute symptoms of self-diagnosed illnesses. Due to the limited availability of primary healthcare services and the anxiety associated with the COVID-19 pandemic, the compulsion to SM by the public has increased considerably. The study aimed to assess the characteristics, practices, and associated factors of SM by the public during the COVID-19 pandemic in Sargodha, Pakistan. χ2-tests and univariable analyses were conducted to explore the identification of characteristics and the potential contributing factors for SM during COVID-19, while multivariable logistic regression models were run to study the effect of variables that maintained a significant association. The study was performed during July−September 2021, with n = 460 questionnaires returned overall (response rate: 99.5%). The majority of respondents were males (58.7%, n = 270) who live in the periphery of the town (63.9%, n = 294), and most of the respondents belonged to the age group of 18−28 years (73.3%, n = 339). A large number, 46.1% (n = 212), of the participants were tested for COVID-19 during the pandemic, and among them, 34.3% (n = 158) practiced SM during the pandemic; the most common source of obtaining medicines was requesting them directly from a pharmacy (25.0%; n = 127). The chances of practicing SM for medical health professionals were 1.482 (p-value = 0.046) times greater than for non-medical health personnel. The likelihood of practicing SM in participants whose COVID-19 test was positive was 7.688 (p-value < 0.001) times more than who did not test for COVID-19. Allopathic medicines, acetaminophen (23.6%), azithromycin (14,9%), and cough syrups (13%), and over the counter (OTC) pharmaceuticals, vitamin oral supplements, such as Vitamin C (39.1%), folic acid (23.5%), and calcium (22.6%), were the most commonly consumed medicines and supplements, respectively; being a healthcare professional or having a COVID-test prior showed a significant association with the usage of Vitamin C (p < 0.05 in all cases). Respondents who mentioned unavailability of the physician and difficulty in travelling/reaching healthcare professionals were found 2.062-times (p-value = 0.004) and 1.862-times (p-value = 0.021) more likely to practice SM, respectively; SM due to fear of COVID was more common in individuals who had received COVID-tests prior (p = 0.004). Practices of SM were observed at alarming levels among our participants. Consciousness and understanding about the possible adverse effects of SM must be established and validated on a continuous level; in addition, on a commercial level, collaboration from pharmacists not to sell products (especially prescription-only medicines) without a certified prescription must be developed and implemented.
RESUMO
BACKGROUND: Bloodstream infections in septic patients may be missed due to preceding antibiotic therapy prior to obtaining blood cultures. We leveraged the FABLED cohort study to determine if the quick Sequential Organ Failure Assessment (qSOFA) score could reliably identify patients at higher risk of bacteremia in patients who may have false negative blood cultures due to previously administered antibiotic therapy. METHODS: We conducted a multi-centre diagnostic study among adult patients with severe manifestations of sepsis. Patients were enrolled in one of seven participating centres between November 2013 and September 2018. All patients from the FABLED cohort had two sets of blood cultures drawn prior to the administration of antimicrobial therapy, as well as additional blood cultures within 4 hours of treatment initiation. Participants were categorized according to qSOFA score, with a score ≥2 being considered positive. RESULTS: Among 325 patients with severe manifestations of sepsis, a positive qSOFA score (defined as a score ≥2) on admission was 58% sensitive (95% CI 48% to 67%) and 41% specific (95% CI 34% to 48%) for predicting bacteremia. Among patients with negative post-antimicrobial blood cultures, a positive qSOFA score was 57% sensitive (95% CI 42% to 70%) and 42% specific (95% CI 35% to 49%) to detect patients who were originally bacteremic prior to the initiation of therapy. CONCLUSIONS: Our results suggest that the qSOFA score cannot be used to identify patients at risk for occult bacteremia due to the administration of antibiotics pre-blood culture.
HISTORIQUE: Les infections sanguines peuvent rester non diagnostiquées chez les patients septiques avant l'obtention des cultures sanguines, en raison d'une antibiothérapie antérieure. Les chercheurs ont puisé dans l'étude de cohorte FABLED pour déterminer si le score rapide de l'évaluation séquentielle d'insuffisance des organes (Sequential Organ Failure Assessment, qSOFA) pourrait dépister les patients à plus haut risque de bactériémie avec fiabilité, malgré la possibilité de cultures sanguines faussement négatives en raison d'une antibiothérapie antérieure. MÉTHODOLOGIE: Les chercheurs ont réalisé une étude diagnostique multicentrique chez des patients adultes ayant de graves manifestations de sepsis. Les patients ont été inscrits dans l'un des sept centres participants entre novembre 2013 et septembre 2018. Tous les patients de l'étude de cohorte FABLED avaient subi deux séries de cultures sanguines avant de recevoir une thérapie antimicrobienne, de même qu'une autre série de cultures sanguines dans les quatre heures suivant le début du traitement. Les participants ont été classés en fonction de leur score de qSOFA, un score d'au moins 2 étant considéré comme positif. RÉSULTATS: Chez les 325 patients ayant de graves manifestations de sepsis, un score de qSOFA positif (défini comme un score d'au moins 2) à l'admission était sensible à 58 % (IC à 95 %, 48 % à 67 %) et spécifique à 41 % (IC à 95 %, 34 % à 48 %) pour prédire la bactériémie. Chez les patients dont les cultures sanguines étaient négatives après la prise d'antimicrobiens, un score de qSOFA positif était sensible à 57 % (IC à 95 %, 42 % à 70 %) et spécifique à 42 % (IC à 95 %, 35 % à 49 %) pour dépister les patients atteints d'une bactériémie avant le début du traitement. CONCLUSIONS: Selon les résultats, le score de qSOFA ne peut pas être utilisé pour dépister les patients à risque de bactériémie occulte à cause de l'administration d'antibiotiques avant la culture sanguine.
RESUMO
BACKGROUND: Sepsis is a leading cause of morbidity, mortality, and health care costs worldwide. METHODS: We conducted a multicenter, prospective cohort study evaluating the yield of blood cultures drawn before and after empiric antimicrobial administration among adults presenting to the emergency department with severe manifestations of sepsis. Enrolled patients who had the requisite blood cultures drawn were followed for 90 days. We explored the independent association between blood culture positivity and its time to positivity in relation to 90-day mortality. RESULTS: Three hundred twenty-five participants were enrolled; 90-day mortality among the 315 subjects followed up was 25.4% (80/315). Mortality was associated with age (mean age [standard deviation] in those who died was 72.5 [15.8] compared with 62.9 [17.7] years among survivors; P < .0001), greater Charlson Comorbidity Index (2 [interquartile range {IQR}, 1-3] vs 1 [IQR, 0-3]; P = .008), dementia (13/80 [16.2%] vs 18/235 [7.7%]; P = .03), cancer (27/80 [33.8%] vs 47/235 [20.0%]; P = .015), positive quick Sequential Organ Failure Assessment score (57/80 [71.2%] vs 129/235 [54.9%]; P = .009), and normal white blood cell count (25/80 [31.2%] vs 42/235 [17.9%]; P = .02). The presence of bacteremia, persistent bacteremia after antimicrobial infusion, and shorter time to blood culture positivity were not associated with mortality. Neither the source of infection nor pathogen affected mortality. CONCLUSIONS: Although severe sepsis is an inflammatory condition triggered by infection, its 90-day survival is not influenced by blood culture positivity nor its time to positivity. CLINICAL TRIALS REGISTRATION: NCT01867905.
RESUMO
BACKGROUND: Of all microbiological tests performed, blood cultures have the most impact on patient care. Timely results are essential, especially in the management of sepsis. While there are multiple available blood culture systems on the market, they have never been compared in a prospective study in a critically ill population. METHODS: We performed an analysis of the FABLED study cohort to compare culture results and time to positivity (TTP) of 2 widely used blood culture systems: BacT/Alert and BACTEC. In this multisite prospective study, patients with severe manifestations of sepsis had cultures drawn before antibiotics using systematic enrollment criteria and blood drawing methodology allowing for minimization of pre-analytical biases. RESULTS: We enrolled 315 patients; 144 had blood cultures (47 positive) with BacT/Alert and 171 with BACTEC (53 positive). Patients whose blood cultures were processed using the BacT/Alert system were younger (median, 64 vs 70 years; Pâ =â .003), had a higher proportion of HIV (9.03% vs 1.75%; Pâ =â .008) and a lower qSOFA (Pâ =â .003). There were no statistically significant differences in the most commonly identified bacterial species. TTP was shorter for BACTEC (median [interquartile range {IQR}], 12.5 [10-14] hours) compared with BacT/Alert (median [IQR], 17 [14-21] hours; Pâ <â .0001). CONCLUSIONS: In this large prospective multi-centre study comparing the two blood culture systems among patients with severe manifestations of sepsis, and using a rigorous pre-analytical methodology, the BACTEC system yielded positive culture results 4.5 hours earlier than BacT/Alert. These results apply to commonly isolated bacteria. However, our study design did not allow direct comparison of TTP for unusual pathogens nor of clinical sensitivity between systems. More research is needed to determine the clinical implications of this finding.
RESUMO
Background: Administering antimicrobial agents before obtaining blood cultures could potentially decrease time to treatment and improve outcomes, but it is unclear how this strategy affects diagnostic sensitivity. Objective: To determine the sensitivity of blood cultures obtained shortly after initiation of antimicrobial therapy in patients with severe manifestations of sepsis. Design: Patient-level, single-group, diagnostic study. (ClinicalTrials.gov: NCT01867905). Setting: 7 emergency departments in North America. Participants: Adults with severe manifestations of sepsis, including systolic blood pressure less than 90 mm Hg or a serum lactate level of 4 mmol/L or more. Intervention: Blood cultures were obtained before and within 120 minutes after initiation of antimicrobial treatment. Measurements: Sensitivity of blood cultures obtained after initiation of antimicrobial therapy. Results: Of 3164 participants screened, 325 were included in the study (mean age, 65.6 years; 62.8% men) and had repeated blood cultures drawn after initiation of antimicrobial therapy (median time, 70 minutes [interquartile range, 50 to 110 minutes]). Preantimicrobial blood cultures were positive for 1 or more microbial pathogens in 102 of 325 (31.4%) patients. Postantimicrobial blood cultures were positive for 1 or more microbial pathogens in 63 of 325 (19.4%) patients. The absolute difference in the proportion of positive blood cultures between pre- and postantimicrobial testing was 12.0% (95% CI, 5.4% to 18.6%; P < 0.001). Sensitivity of postantimicrobial culture was 52.9% (CI, 42.8% to 62.9%). When the results of other microbiological cultures were included, microbial pathogens were found in 69 of 102 (67.6% [CI, 57.7% to 76.6%]) patients. Limitation: Only a proportion of screened patients were recruited. Conclusion: Among patients with severe manifestations of sepsis, initiation of empirical antimicrobial therapy significantly reduces the sensitivity of blood cultures drawn shortly after treatment initiation.

OBJECTIVES: Creon 10 Minimicrospheres is an enteric-coated, delayed-release pancrelipase preparation designed to deliver active pancreatic enzymes to the small intestine. The primary objective of this study was to compare the effect of Creon 10 with placebo in the control of steatorrhea in chronic pancreatitis patients. Secondary objectives included evaluation of stool parameters and global improvement of symptoms scales. METHODS: The study was a randomized, double-blind, placebo-controlled, 2-week trial. After a placebo run-in ("washout") phase, the effect on coefficient of fat absorption (%), daily fat excretion before and after treatment, and stool frequency and consistency were assessed. RESULTS: In Creon 10-treated subjects, the change in mean coefficient of fat absorption (%) from run-in to double-blind phase was significantly higher compared with placebo-treated subjects (+36.7 vs. +12.1, P = 0.0185). Stool consistency improved significantly more with Creon 10 than with placebo (P = 0.0102) resulting in more subjects with formed stool; stool frequency decreased significantly more with Creon 10 than with placebo (P = 0.0015) from 10.8 during placebo run-in to 5.2 stools per day during double-blind treatment; and daily mean fat excretion in stool decreased significantly more (-56.5 vs. -11.4 g/d, P = 0.0181) in Creon 10-treated subjects compared with placebo-treated subjects. Global disease symptom scores showed greater improvement for both physicians and subjects in the Creon 10 group relative to those receiving placebo. Between treatment difference reached statistical significance for Creon 10 (P = 0.0435) for physician score and showed a trend (P = 0.0634) favoring Creon for subject score. CONCLUSIONS: This randomized, placebo-controlled trial found that Creon 10 treatment controlled steatorrhea, as reflected in reduced fat excretion, decreased stool frequency and improved stool consistency. Creon 10 treatment was safe and well tolerated.

A 50-year-old White man with noncirrhotic portal hypertension presented with bleeding from gastric varices. Bleeding was initially managed with band ligation and subsequent transjugular intrahepatic portosystemic shunt (TIPS). Over the next few months, the patient had recurrent episodes of anemia, jaundice, fever and polymicrobial bacteremia. Computed tomography (CT) of the abdomen and chest, upper and lower endoscopy, endoscopic retrograde cholangiopancreatography (ERCP), and echocardiography failed to explain the bacteremia and anemia. Follow-up CT scan and Doppler sonography 9 months after placement showed TIPS was occluded. Repeat ERCP showed a bile leak with free run-off of contrast from the left hepatic duct into a vascular structure. The patient's status was upgraded for liver transplantation with Regional Review Board agreement and subsequently received a liver transplant. Gross examination of the native liver demonstrated a fistula between the left bile duct and the middle hepatic vein. Pathologic evaluation confirmed focal necrosis of the left hepatic duct communicating with an occluded TIPS and nodular regenerative hyperplasia consistent with noncirrhotic portal hypertension. Infection is rarely reported in a totally occluded TIPS. Biliary fistulas in patent TIPS have been treated by endoluminal stent graft and endoscopic sphincterotomy with biliary stent placement. Liver transplantation may be the preferred treatment if TIPS becomes infected following its complete occlusion.
