ABSTRACT

Background: Sickle cell disease (SCD) is a disorder marked by a single-point mutation in the beta-globin gene. Hydroxyurea is a globally accepted disease-modifying agent that sounds to be effective in managing clinically and probably preventing complications of SCD. The current study aims to document the morbidity pattern and impact of Hydroxyurea therapy in the Outpatient Department of Sickle Cell Institute, Raipur. Materials and Methods: This cross-sectional study was conducted among randomly selected sixty-five patients (adults and children above six years). After obtaining informed consent, relevant data were collected in a predesigned pretested questionnaire. The appropriate statistical exercise was applied for the interpretation of results and inferences. Results: Acute febrile illness 54 (83%) and 53 (81.5%) reported pain crisis observed to have the most common morbidity among the study subjects, followed by 55.4% (36), 33 (50.8%) jaundice and difficulty breathing, respectively. Joint pain was the most commonly observed complaint, particularly at the knee joint (76.9%). Other complaints such as hand-foot syndrome (24.6%), epistaxis (27.7%), and acute chest syndrome (21.5%). Vaso-occlusive crisis (72.4%), difficulty in walking (60.0%) and eyesight (35.4%), leg ulcers (9.2%), and dactylitis (3.1%) were also documented as clinical manifestations among study participants. Less than half (44.46%) had an awareness about SCD. Hydroxyurea therapy was highly significant in improving the patient's clinical picture (P < 0.01), especially following the frequency of hospitalization and the requirement for blood transfusion. Conclusion: Pain crisis is the most common morbidity among study participants with a low level of knowledge about SCD with febrile illness. Hydroxyurea therapy was found to be quite effective as a disease-modifying therapy, especially for reducing the frequency of blood transfusion and lowering hospitalization rates among SCD patients.

ABSTRACT

At 3 severe infection cohort sites in Uganda, Orientia seropositivity was common. We identified 4 seroconversion cases and 1 PCR-positive case. These results provide serologic and molecular support for Orientia spp. circulating in sub-Saharan Africa, possibly expanding its endemic range. Orientia infections could cause severe illness and hospitalizations in this region.

ABSTRACT

The majority of cases of undifferentiated acute febrile illness (AFI) in the tropics have an undefined etiology. In Thailand, AFI accounts for two-thirds of illnesses reported to the Ministry of Public Health. To characterize the bacterial and viral causes of these AFIs, we conducted molecular pathogen screening and serological analyses in patients who sought treatment in Chum Phae Hospital, Khon Kaen province, during the period from 2015 to 2016. Through integrated approaches, we successfully identified the etiology in 25.5% of cases, with dengue virus infection being the most common cause, noted in 17% of the study population, followed by scrub typhus in 3.8% and rickettsioses in 6.8%. Further investigations targeting viruses in patients revealed the presence of Guadeloupe mosquito virus (GMV) in four patients without other pathogen co-infections. The characterization of four complete genome sequences of GMV amplified from AFI patients showed a 93-97% nucleotide sequence identity with GMV previously reported in mosquitoes. Nucleotide substitutions resulted in amino acid differences between GMV amplified from AFI patients and mosquitoes, observed in 37 positions. However, these changes had undergone purifying selection pressure and potentially had a minimal impact on protein function. Our study suggests that the GMV strains identified in the AFI patients are relatively similar to those previously reported in mosquitoes, highlighting their potential role associated with febrile illness.

ABSTRACT

Introduction: Acute febrile illnesses (AFI) in developing tropical and sub-tropical nations are challenging to diagnose due to the numerous causes and non-specific symptoms. The proliferation of rapid diagnostic testing and successful control campaigns against malaria have revealed that non-Plasmodium pathogens still contribute significantly to AFI burden. Thus, a more complete understanding of local trends and potential causes is important for selecting the correct treatment course, which in turn will reduce morbidity and mortality. Next-generation sequencing (NGS) in a laboratory setting can be used to identify known and novel pathogens in individuals with AFI. Methods: In this study, plasma was collected from 228 febrile patients tested negative for malaria at clinics across Senegal from 2020-2022. Total nucleic acids were extracted and converted to metagenomic NGS libraries. To identify viral pathogens, especially those present at low concentration, an aliquot of each library was processed with a viral enrichment panel and sequenced. Corresponding metagenomic libraries were also sequenced to identify non-viral pathogens. Results and Discussion: Sequencing reads for pathogens with a possible link to febrile illness were identified in 51/228 specimens, including (but not limited to): Borrelia crocidurae (N = 7), West Nile virus (N = 3), Rickettsia felis (N = 2), Bartonella quintana (N = 1), human herpesvirus 8 (N = 1), and Saffold virus (N = 1). Reads corresponding to Plasmodium falciparum were detected in 19 specimens, though their presence in the cohort was likely due to user error of rapid diagnostic testing or incorrect specimen segregation at the clinics. Mosquito-borne pathogens were typically detected just after the conclusion of the rainy season, while tick-borne pathogens were mostly detected before the rainy season. The three West Nile virus strains were phylogenetically characterized and shown to be related to both European and North American clades. Surveys such as this will increase the understanding of the potential causes of non-malarial AFI, which may help inform diagnostic and treatment options for clinicians who provide care to patients in Senegal.

ABSTRACT

Background: With growing use of parasitological tests to detect malaria and decreasing incidence of the disease in Africa; it becomes necessary to increase the understanding of causes of non-malaria acute febrile illness (NMAFI) towards providing appropriate case management. This research investigates causes of NMAFI in pediatric out-patients in rural Guinea-Bissau. Methods: Children 0-5 years presenting acute fever (≥38°) or history of fever, negative malaria rapid diagnostic test (mRDT) and no signs of specific disease were recruited at the out-patient clinic of 3 health facilities in Bafatá province during 54 consecutive weeks (dry and rainy season). Medical history was recorded and blood, nasopharyngeal, stool and urine samples were collected and tested for the presence of 38 different potential aetiological causes of fever. Results: Samples from 741 children were analysed, the protocol was successful in determining a probable aetiological cause of acute fever in 544 (73.61%) cases. Respiratory viruses were the most frequently identified pathogens, present in the nasopharynx samples of 435 (58.86%) cases, followed by bacteria detected in 167 (22.60%) samples. Despite presenting negative mRDTs, P. falciparum was identified in samples of 24 (3.25%) patients. Conclusions: This research provides a description of the aetiological causes of NMAFI in West African context. Evidence of viral infections were more commonly found than bacteria or parasites.

ABSTRACT

Objectives: Acute febrile illness (AFI) causes significant health-seeking, morbidity, and mortality in Southeast Asia. This pilot study aimed to describe presentation, etiology, treatment, and outcomes of patients with AFI at one hospital in Timor-Leste and assessing the feasibility of conducting larger studies in this setting. Methods: Patients attending Hospital Nacional Guido Valadares with tympanic or axillary temperature ≥37.5°C in whom a blood culture was taken as part of routine clinical care were eligible. Participants were followed up daily for 10 days and again after 30 days. Whole blood was analyzed using a real-time quantitative polymerase chain reaction assay detecting dengue virus serotypes 1-4 and other arthropod-borne infections. Results: A total of 82 participants were recruited. Polymerase chain reaction testing was positive for dengue in 14 of 82 (17.1%) participants and blood culture identified a bacterial pathogen in three of 82 (3.7%) participants. Follow-up was completed by 75 of 82 (91.5%) participants. High rates of hospital admission (58 of 82, 70.7%), broad-spectrum antimicrobial treatment (34 of 82, 41.5%), and mortality (9 of 82, 11.0%) were observed. Conclusions: Patients with AFI experience poor clinical outcomes. Prospective observational and interventional studies assessing interventions, such as enhanced diagnostic testing, clinical decision support tools, or antimicrobial stewardship interventions, are required and would be feasible to conduct in this setting.

ABSTRACT

In September 2022, Panchkula Civil Hospital reported an outbreak of acute febrile illness (AFI) in Pinjore, located in the Himalayan foothills, Haryana, North India. There was an upsurge of fever cases. Blood samples were taken from suspected patients (n = 58) with AFI and subjected to serology of dengue, chikungunya, Japanese encephalitis, leptospira and scrub typhus. The samples were also screened for West Nile & Zika virus RNA using real-time PCR. Viral strains were characterized by sequencing. Of the 58 cases of AFI, Dengue could be identified in 45 (77.58%) followed by JE and Chikungunya in 2 cases each (3.44%), respectively. Among Dengue positive cases, 44 had monoinfection (97.77%) and 1 patient had dengue and JE. None were positive for Zika, West Nile, Scrub typhus, and Leptospira with the testing protocol. Four patients developed dengue with warning signs, such as abdominal pain in one patient and recurrent vomiting in the remaining three. The dengue serotype could be determined in 17 samples and revealed serotype 2. Molecular evolution analysis based on the complete envelope gene revealed that all DENV-2 strains (n = 13) circulated in the outbreak area belonged to the DENV-2 cosmopoliton genotype. In the early stages of infection, relying only on clinical manifestations is ineffective, so both molecular and serological assays along with clinical diagnosis are noteworthy for determining the aetiology of AFI.

ABSTRACT

OBJECTIVE: This study was undertaken to assess the effectiveness of Eupatorium perfoliatum (EP) 30C on the incidence of dengue fever and acute febrile illness (AFI) during the 2017 dengue outbreak. METHODS: We conducted a prospective, open-label, community-based parallel cohort study involving apparently healthy individuals residing in 06 urban slums (JJ colony) of Delhi. The participants were enrolled in two cohorts - the medicine cohort (MC) and the control cohort (CC). Participants in MC were given weekly one dose of EP 30C for 10 weeks along with Information, Education and Communication (IEC) material regarding dengue. Participants in the CC were provided with the IEC material only. The primary outcome measure was the incidence of dengue fever as per case definitions notified in the national guidelines for clinical management of dengue fever by the Government of India during the 10 weeks follow-up period. The secondary outcome measures were the incidence of AFI and the hospitalization of confirmed dengue cases. RESULTS: The analysis included 40,769 participants residing in 06 slum clusters of Delhi out of which 28,321 participants were in MC and 12,448 participants were in CC. The incidence of laboratory-confirmed dengue in the MC was 2.57 per 10,000 person-weeks (95% confidence interval [CI], 2.02-3.22) in comparison with 7.55 per 10,000 person-weeks (95% CI, 6.12-9.21) in the CC. The incidence of AFI in the MC was 19.66 per 10,000 person-weeks (95% CI, 18.07-21.36) in comparison with 40.96 per 10,000 person-weeks (95% CI, 37.48-44.67) in the CC. The overall protective effect of EP against laboratory-confirmed dengue was 65.77% (95% CI, 53.37-74.87; p = 0.0001) and against AFI was 52.58% (95% CI, 46.37-58.07; p = 0.0001). Hospitalization reported in the MC was nil as against 4.35% in the CC. No dengue-related case fatalities were reported from either cohort. None of the participants from the MC reported any adverse events owing to the prophylactic intervention. CONCLUSION: The study concludes that EP 30C was able to prevent dengue significantly. Randomized controlled trials are needed to confirm or refute our findings.ZielDas Ziel dieser Studie war die Beurteilung der Wirksamkeit von Eupatorium perfoliatum (EP) 30C auf die Inzidenz von Dengue-Fieber und akuter fiebriger Erkrankung (AFE) während des Dengue-Ausbruchs 2017.MethodenWir führten eine prospektive, unverblindete, Bevölkerungs-Parallelgruppen-Kohortenstudie mit augenscheinlich gesunden Bewohnern von 6 städtischen Slums (JJ-Kolonie) in Delhi durch. Die Teilnehmer wurden in 2 Kohorten aufgenommen, einer Medizinkohorte (MK) und einer Kontrollkohorte (KK). Die Teilnehmer in der MK erhielten 10 Wochen lang wöchentlich eine Dosis EP 30C und dazu Aufklärungsmaterialien über Dengue. Die Teilnehmer in der KK erhielten nur die Aufklärungsmaterialien. Die primäre Zielgröße war die Dengue-Fieber-Inzidenz laut der in den nationalen Leitlinien für das klinische Management des Dengue-Fiebers von der indischen Regierung bekannt gegebenen Falldefinition in dem zehnwöchigen Beobachtungszeitraum. Die sekundären Zielgrößen waren die Inzidenz von AFE und die Anzahl hospitalisierter bestätigter Dengue-Fälle.ErgebnisseIn die Analyse wurden 40,769 Bewohner von 6 Slum-Clustern in Delhi einbezogen, davon wurden 28,321 Teilnehmer in die MK aufgenommen und 12,448 Teilnehmer in die KK. Die Inzidenz von im Labor bestätigter Dengue betrug in der MK 2,57 pro 10,000 Personen/Woche (95%-Konfidenzintervall [KI]: 2,02­3,22), verglichen mit 7,55 pro 10,000 Personen/Woche (95%-KI: 6,12­9,21) in der KK. Die Inzidenz von AFI betrug in der MK 19,66 pro 10,000 Personen/Woche (95%-Konfidenzintervall [KI]: 18,07­21,36), verglichen mit 40,96 pro 10,000 Personen/Woche (95%-KI: 37,48­44,67) in der KK. Der Schutzeffekt (SE) von EP betrug gegen im Labor bestätigte Dengue 65,77% (95%-KI: 53,37­74,87; p = 0,0001) und gegen AFI 52,58% (95%-KI: 46,37­58,07; p = 0,0001). Die Hospitalisierungsrate war in der MK gleich Null versus 4,35% in der KK. In keiner Kohorte waren Dengue-bedingte Todesfälle zu verzeichnen. Bei keinem der Teilnehmer in der MK traten jegliche unerwünschten Ereignisse infolge der prophylaktischen Maßnahme auf.SchlussfolgerungDie Studie gelangt zu dem Schluss, dass Eupatorium perfoliatum 30C in signifikantem Maße Dengue vorbeugen konnte. Randomisierte kontrollierte Studien sind erforderlich, um unsere Ergebnisse zu bestätigen bzw. zu widerlegen.

ABSTRACT

Introduction: Acute febrile illness (AFI) patients present to the emergency department (ED), with fever to multi-organ dysfunction. There is a lack of early point-of-care-based disposition criteria in AFI patients regarding the need for intensive care unit (ICU) or high dependency unit (HDU) care. Methods: We enrolled 100 patients with AFI presenting to the ED and evaluated using point-of-care ultrasound with two-dimensional echocardiography (ECHO), lung ultrasound score (LUS), renal arterial resistive index (RRI), and arterial blood gas. The need for ICU/HDU admission, ventilation (either noninvasive or invasive), and renal-replacement therapy (RRT) within 48 h of hospitalization was noted. Results: Ninety-five patients were included in the analysis. 72 (75.8%) patients required either ICU or HDU admission, 45 (47.4%) required ventilatory support (either noninvasive or invasive), and 32 (33.7%) required RRT. After logistic regression, LUS ≥16, and arterial lactate ≥12 mg/dL were independent predictors of the need for ICU or HDU admission. The respiratory rate (RR) ≥28/minute, LUS ≥16 and RRI ≥61 were the independent predictors of the need for ventilation. The MAP ≤73 mmHg, LUS (≥16), and RRI (≥67) were the predictors of the need for RRT. Conclusion: In AFI patients presenting to the ED, the MAP, LUS, and lactate are predictors of the need for ICU/HDU admission. The LUS and RRI were predictors of the need for RRT whereas the RR, LUS, and RRI were the predictors of the need for ventilation.

ABSTRACT

Introduction: Overlapping symptoms between dengue and coronavirus disease 2019 (COVID-19) may become a diagnostic challenge; moreover, social stigma and fear of being diagnosed with COVID-19 may lead the patients to delayed medical visit. Delayed medical management of dengue may lead to expanded dengue syndrome and a fatal outcome. Case presentation: A 35-year-old female patient with uncontrolled diabetes mellitus and a recent COVID-19 infection presented with a continuous fever for 4 days. She delayed seeking medical advice due to traumatized being infected by COVID-19, the self-isolation protocol, and the COVID-19 protocol in every hospital for every febrile patient. She developed multiorgan failure during her hospitalization and was diagnosed with expanded dengue syndrome. Clinical discussion: Diagnosing the etiology of acute febrile illness in the COVID-19 pandemic era is problematic. Most of healthcare facilities warranted COVID-19 evaluation in every acute febrile patient. This protocol may lead to a potential delayed diagnosis and serve as a barrier to accessing healthcare facility. False perception, fear and anxiety of being isolated, discrimination in society, and others may lead to stigmatization of COVID-19 and affect the individual decision for COVID-19 testing and seeking medical advices. Our patient had a fatal outcome due to delayed detection and treatment of dengue hemorrhagic fever. Conclusion: Delayed management of expanded dengue syndrome leads to a fatal outcome. Stigma may play a role as the barrier for seeking medical advice. Having a broad differential diagnosis in COVID-19 pandemic era is essential.

ABSTRACT

BACKGROUND: Rickettsial pathogens are Gram-negative, obligate intracellular bacteria. They are transmitted by arthropods and are responsible for a wide variety of disease, from minor to life-threatening, which have a global effect on human health. Limited data are available on the prevalence of rickettsial diseases from India, and the disease epidemiology is not fully described. This study aimed to diagnose non-scrub typhus rickettsioses including spotted fever and typhus group of Rickettsia in clinically suspected patients by using standard serological tests and recognition of common epidemiological conditions and clinical manifestations. METHODS: During the study period, a total of 700 patients of all ages with acute febrile illness were enrolled. Patients were screened for rickettsial infection using IgM Enzyme-linked immunosorbent assay (ELISA) and Immunofluorescence assay (IFA) was performed to confirm the ELISA positive results. The relevant demographic, clinical, and laboratory details of patients were documented and analyzed. RESULTS: Of 700 samples tested, 141 (20.2%) were found to be positive for IgM antibodies against rickettsioses using ELISA and IFA. SFGR was positive in 15 (2.2%), TGR was positive in 112 (16%) and 14 (2%) samples were positive for both groups. 20 (14.2%) patients required admission to the intensive care unit (ICU), and 24 (17%) in-hospital deaths occurred. CONCLUSIONS: The prevalence of rickettsioses in India appears to be underestimated; therefore, increased awareness and improved diagnostic testing could facilitate early detection of cases, pathogen-targeted appropriate treatment, and improved outcomes for patients. Despite the fact that Rickettsiae can be isolated or detected using molecular techniques in clinical specimens, serology still remains the most commonly used diagnostic method for rickettsioses around the world. Our study helps bridge the gap of limited data on Rickettsia in north India and could be useful for future epidemiological investigation of rickettsial diseases and outbreaks.

ABSTRACT

Introduction: Leptospirosis is a zoonotic bacterial infection with significant mortality and morbidity, especially in resource-limited settings. This systematic review aimed to study the clinical profile and outcome of patients with leptospirosis in India. Methodology: All articles up to 02.08.2022 were searched using the two databases, PubMed and Scopus. A total of 542 articles were found using the search terms related to 'leptospirosis' and 'India'. After two rounds of screening, 55 articles were included. The data were collected on epidemiology, clinical features, laboratory features and treatment of patients with leptospirosis. Results: Most cases of leptospirosis were reported from the coastal belt. A large percentage of patients were identified as farmers, and exposure to rainfall was identified as an important risk factor. Fever was present in 97%, and conjunctival suffusion was present in 35% of cases. Haemoptysis, gastrointestinal bleeding, and haematuria were present in 5%, 5% and 12% of patients, respectively. Liver and kidney were involved in 34% and 35% of the patients, respectively. The average haemoglobin, leucocyte count and platelet count across various studies ranged from 9.6-12.5 grams/dl, 8.8-11.3 thousand/µl and 20-130 thousand/µl, respectively. Treatment details were sparsely available in some studies, with penicillin, ceftriaxone, and doxycycline used commonly. The pooled mortality across various studies was calculated as 11% [95% CI-8-15%, I2=93%, P<0.001]. Conclusions: Leptospirosis is associated with significant mortality in Indian settings. There is a need for studies focussing on treatment modalities.

ABSTRACT

Scrub typhus is transmitted by the bite of chiggers (larvae) of Leptotrombidium deliense and is caused by the bacteria Orientia tsutsugamushi. Common symptoms include fever, headache, lymphadenopathy, and black eschar formation, while acute pancreatitis is a rare complication. We present the case of a 27-year-old gentleman, who presented with epigastric pain and constipation for three weeks, fever for four days, and vomiting for two days. Serum lipase, C-reactive protein, and serum amylase were significantly raised. Enzyme-linked immunosorbent assay anti-scrub typhus IgM was positive at 0.605 optical density. An abdominal computed tomography scan revealed a bulky pancreas. Mild fluid collection (50 × 60 × 65 mm) was seen in the peripancreatic region, along with moderate to gross mesenteric fat stranding. The left anterior and lateral renal conal fascia were thickened and edematous. The patient was managed with intravenous fluids, antipyretics, and intravenous doxycycline.

ABSTRACT

The differentiation of dengue virus (DENV) infection, a major cause of acute febrile illness in tropical regions, from other etiologies, may help prioritize laboratory testing and limit the inappropriate use of antibiotics. While traditional clinical prediction models focus on individual patient-level parameters, we hypothesize that for infectious diseases, population-level data sources may improve predictive ability. To create a clinical prediction model that integrates patient-extrinsic data for identifying DENV among febrile patients presenting to a hospital in Thailand, we fit random forest classifiers combining clinical data with climate and population-level epidemiologic data. In cross validation, compared to a parsimonious model with the top clinical predictors, a model with the addition of climate data, reconstructed susceptibility estimates, force of infection estimates, and a recent case clustering metric, significantly improved model performance.

ABSTRACT

BACKGROUND: Increasing trends of antimicrobial resistance are observed around the world, driven in part by excessive use of antimicrobials. Limited access to diagnostics, particularly in low- and middle-income countries, contributes to diagnostic uncertainty, which may promote unnecessary antibiotic use. We investigated whether introducing a package of diagnostic tools, clinical algorithm, and training-and-communication messages could safely reduce antibiotic prescribing compared with current standard-of-care for febrile patients presenting to outpatient clinics in Uganda. METHODS: This was an open-label, multicenter, 2-arm randomized controlled trial conducted at 3 public health facilities (Aduku, Nagongera, and Kihihi health center IVs) comparing the proportions of antibiotic prescriptions and clinical outcomes for febrile outpatients aged ≥1 year. The intervention arm included a package of point-of-care tests, a diagnostic and treatment algorithm, and training-and-communication messages. Standard-of-care was provided to patients in the control arm. RESULTS: A total of 2400 patients were enrolled, with 49.5% in the intervention arm. Overall, there was no significant difference in antibiotic prescriptions between the study arms (relative risk [RR]: 1.03; 95% CI: .96-1.11). In the intervention arm, patients with positive malaria test results (313/500 [62.6%] vs 170/473 [35.9%]) had a higher RR of being prescribed antibiotics (1.74; 1.52-2.00), while those with negative malaria results (348/688 [50.6%] vs 376/508 [74.0%]) had a lower RR (.68; .63-.75). There was no significant difference in clinical outcomes. CONCLUSIONS: This study found that a diagnostic intervention for management of febrile outpatients did not achieve the desired impact on antibiotic prescribing at 3 diverse and representative health facility sites in Uganda.

ABSTRACT

BACKGROUND: The aim was to explore behavioral factors relating to the prescription and communication of prescription-adherence messages for patients with acute febrile illness, from which to develop a training-and-communication (T&C) intervention to be delivered as part of a clinical trial. METHODS: The study undertook a content analysis of primary, qualitative data collection using in-depth interviews and focus group discussions, informed by the Capability, Opportunity, Motivation (COM-B) theory of behavior, the Theoretical Domains Framework (TDF), and Behavior Change Wheel (BCW) approach, in health facilities (39 health workers) and communities (66 community members) in the Shai-Osudoku District of Ghana. RESULTS: Health workers perceive that prescribers' and dispensers' communication with patients is influenced by the following factors: patient's educational level, existing disease conditions, health worker's workload, patient's religion, language barrier between health worker and patient, outcome of laboratory results, and medicine availability. Community members' adherence to prescription was influenced by the availability of money and affordability of medicine (outside of provision by the national health insurance scheme), the severity of the condition, work schedule, and forgetfulness. CONCLUSIONS: Our study contributes to knowledge on nesting qualitative methods in a clinical trial and reveals factors that affect the antibiotic prescription communication process. Tailored messages for patient-specific needs can shape antibiotic prescription adherence behavior and ultimately contribute to decreasing the incidence of antibiotic resistance.

ABSTRACT

BACKGROUND: Antibiotic prescribing practices are 1 of the contributing causes of antimicrobial resistance (AMR). The study explored the key drivers and barriers to adherence to prescribing instructions among healthcare workers and outpatient attendees with the aim of developing a training and communication intervention to improve adherence to prescription. METHODS: Prior to randomized trials at 3 health centers in Uganda (Aduku, Kihihi, and Nagongera), a pre-intervention qualitative assessment was conducted to explore behavioral drivers for adherence to prescriptions and the communication of adherence messages. Based on the findings, a training and communication package was developed for healthcare workers and patients at Day 0 of the trial. During the trial's Day 7 patient follow-up, in-depth interviews were conducted to further investigate adherence behaviors. RESULTS: Five main themes were identified that acted as drivers or barriers to prescription adherence. Key drivers included: drug availability at health facility, health worker knowledge, and communication to patients. Barriers included: care-seeker use of treatment resorts and an inability by care-seeker to buy drugs. CONCLUSIONS: The T&C appeared to influence both health workers' and patients' behavior and improve adherence to prescription.The adapted T&C should be considered a toolkit to improve antibiotic use across health facilities accompanied with appropriate guidelines to mitigate AMR.

ABSTRACT

BACKGROUND: Low- and middle-income countries face significant challenges in differentiating bacterial from viral causes of febrile illnesses, leading to inappropriate use of antibiotics. This trial aimed to evaluate the impact of an intervention package comprising diagnostic tests, a diagnostic algorithm, and a training-and-communication package on antibiotic prescriptions and clinical outcomes. METHODS: Patients aged 6 months to 18 years with fever or history of fever within the past 7 days with no focus, or a suspected respiratory tract infection, arriving at 2 health facilities were randomized to either the intervention package or standard practice. The primary outcomes were the proportions of patients who recovered at day 7 (D7) and patients prescribed antibiotics at day 0. RESULTS: Of 1718 patients randomized, 1681 (97.8%; intervention: 844; control: 837) completed follow-up: 99.5% recovered at D7 in the intervention arm versus 100% in standard practice (P = .135). Antibiotics were prescribed to 40.6% of patients in the intervention group versus 57.5% in the control arm (risk ratio: 29.3%; 95% CI: 21.8-36.0%; risk difference [RD]: -16.8%; 95% CI: -21.7% to -12.0%; P < .001), which translates to 1 additional antibiotic prescription saved every 6 (95% CI: 5-8) consultations. This reduction was significant regardless of test results for malaria, but was greater in patients without malaria (RD: -46.0%; -54.7% to -37.4%; P < .001), those with a respiratory diagnosis (RD: -38.2%; -43.8% to -32.6%; P < .001), and in children 6-59 months old (RD: -20.4%; -26.0% to -14.9%; P < .001). Except for the period July-September, the reduction was consistent across the other quarters (P < .001). CONCLUSIONS: The implementation of the package can reduce inappropriate antibiotic prescription without compromising clinical outcomes.

ABSTRACT

BACKGROUND: Historically, malaria has been the predominant cause of acute febrile illness (AFI) in sub-Saharan Africa. However, during the last two decades, malaria incidence has declined due to concerted public health control efforts, including the widespread use of rapid diagnostic tests leading to increased recognition of non-malarial AFI etiologies. Our understanding of non-malarial AFI is limited due to lack of laboratory diagnostic capacity. We aimed to determine the etiology of AFI in three distinct regions of Uganda. METHODS: A prospective clinic-based study that enrolled participants from April 2011 to January 2013 using standard diagnostic tests. Participant recruitment was from St. Paul's Health Centre (HC) IV, Ndejje HC IV, and Adumi HC IV in the western, central and northern regions, which differ by climate, environment, and population density. A Pearson's chi-square test was used to evaluate categorical variables, while a two-sample t-test and Krukalis-Wallis test were used for continuous variables. RESULTS: Of the 1281 participants, 450 (35.1%), 382 (29.8%), and 449 (35.1%) were recruited from the western, central, and northern regions, respectively. The median age (range) was 18 (2-93) years; 717 (56%) of the participants were female. At least one AFI pathogen was identified in 1054 (82.3%) participants; one or more non-malarial AFI pathogens were identified in 894 (69.8%) participants. The non-malarial AFI pathogens identified were chikungunya virus, 716 (55.9%); Spotted Fever Group rickettsia (SFGR), 336 (26.2%) and Typhus Group rickettsia (TGR), 97 (7.6%); typhoid fever (TF), 74 (5.8%); West Nile virus, 7 (0.5%); dengue virus, 10 (0.8%) and leptospirosis, 2 (0.2%) cases. No cases of brucellosis were identified. Malaria was diagnosed either concurrently or alone in 404 (31.5%) and 160 (12.5%) participants, respectively. In 227 (17.7%) participants, no cause of infection was identified. There were statistically significant differences in the occurrence and distribution of TF, TGR and SFGR, with TF and TGR observed more frequently in the western region (p = 0.001; p < 0.001) while SFGR in the northern region (p < 0.001). CONCLUSION: Malaria, arboviral infections, and rickettsioses are major causes of AFI in Uganda. Development of a Multiplexed Point-of-Care test would help identify the etiology of non-malarial AFI in regions with high AFI rates.
