RESUMO
BACKGROUND: The effectiveness of the early treatment for antiviral agents in SARS-CoV-2 infection is closely related to patient comorbidities. Data on effectiveness in immunocompromised patients are limited, with reports involving highly heterogeneous and not well-defined populations. We aimed to assess the effectiveness of treatment in reducing hospitalizations in a real-world cohort of severely immunocompromised COVID-19 outpatients. PATIENTS AND METHODS: We conducted a multicentre, retrospective, observational cohort study of immunocompromised outpatients attended in infectious diseases departments from 1 January to 31 December 2022. Propensity score matching (PSM) multivariable logistic regression models were used to estimate the adjusted odds ratio [(aOR, 95% confidence interval (CI)] for the association between antiviral prescription and outcome (COVID-19-related hospitalization up to Day 90). RESULTS: We identified 746 immunocompromised outpatients with confirmed SARS-CoV-2 infection. After eligibility criteria and PSM, a total of 410 patients were analysed: 205 receiving treatment (remdesivir, sotrovimab or nirmatrelvir/ritonavir) and 205 matched controls. Fifty-two patients required at least one COVID-19-related hospitalization 8 (3.9%) versus 44 (21.5%) in the antiviral and matched control cohorts, respectively. There were 13 deaths at 90â days, of which only 4 were COVID-19-related and none in the antiviral treatment group. After adjustment for residual confounders, the use of early therapy was associated with a protective effect on the risk of hospitalization [aOR 0.13 (0.05-0.29)], as was the use of biological immunomodulators [aOR 0.27 (0.10-0.74)], whereas chronic obstructive pulmonary disease [aOR 4.65 (1.09-19.69)] and anti-CD20 use [aOR 2.76 (1.31-5.81)] increased the odds. CONCLUSIONS: Early antiviral treatment was associated with a reduced risk of COVID-19-related hospitalization in ambulatory severely immunocompromised COVID-19 patients.
RESUMO
We conducted a multicentre observational study in people living with HIV (PLHIV) on antiretroviral therapy in Alicante (Spain) from 2019 to 2020 aiming to analyse the prevalence of abuse and assess treatment adherence according to this variable. We used the Abuse Assessment Screen tool, the simplified medication adherence questionnaire and the medication possession ratio to assess outcomes.. Of the 161 included PLHIV, 53 (32.9%) had suffered abuse (27 emotional abuse, 6 physical abuse, 3 sexual abuse, 13 emotional and physical abuse, 4 unknown type). Seven (4.3%) had suffered abuse in the last year (5 emotional, 2 physical). Abuse had lasted a median of 48 months (interquartile range 12-81). HIV status was considered as a cause of violence by 9.4% of victims. In the multivariable analysis, only abuse was independently associated with non-adherence [adjusted odds ratio (aOR) 3.92; 95% confidence interval (CI) 1.80-8.84; p = 0.0007]. Abuse (aOR 6.14; 95% CI 1.63-27.70; p = 0.001) and previous incarceration (aOR 15.08 95% CI 2.71-104.71; p = 0.003) were associated with detectable viral load. In conclusion, the prevalence of abuse is high in PLHIV, hampering adherence and virological success. Abuse screening tools should be incorporated into routine HIV care.

Immunoregulatory networks may have a role in controlling parasitemia in the chronic phase of human Chagas disease. The aim was to describe the serum cytokine profile of Trypanosoma cruzi in chronically infected patients and to evaluate its relationship with parasitemia and Chagas cardiomyopathy.This prospective observational study included adult patients with chronic Chagas disease. Demographic and clinical data were collected, and peripheral blood samples were used to perform T. cruzi real-time polymerase chain reaction (RT-PCR) and determine the serum cytokine profile.Fifty-eight patients were included; 17 (29.3%) had positive RT-PCR results. This group had a higher median concentration of TNF-α (p = 0.003), IL-6 (p = 0.021), IL-4 (p = 0.031), IL-1ß (p = 0.036), and IL-17A (p = 0.043) than those with a negative RT-PCR. Patients with cardiac involvement had a higher median concentration of IL-5 (p = 0.016) than those without.These results reinforce the key role that cytokines play in Chagas disease patients with parasitemia and cardiac involvement.

OBJECTIVE: To compare the cost-utility of microscopic observation drug-susceptibility assay (MODS) and Xpert® MTB/RIF implementation for tuberculosis (TB) diagnosis in rural northern Mozambique. METHODS: Stochastic transmission compartmental TB model from the healthcare provider perspective with parameter input from direct measurements, systematic literature reviews and expert opinion. MODS and Xpert® MTB/RIF were evaluated as replacement test of smear microscopy (SM) or as an add-on test after a negative SM. Costs were calculated in 2013 USD, effects in disability-adjusted life years (DALY). Willingness to pay threshold (WPT) was established at once the per capita Gross National Income of Mozambique. RESULTS: MODS as an add-on test to negative SM produced an incremental cost-effectiveness ratio (ICER) of 5647.89USD/DALY averted. MODS as a substitute for SM yielded an ICER of 5374.58USD/DALY averted. Xpert® MTB/RIF as an add-on test to negative SM yielded ICER of 345.71USD/DALY averted. Xpert® MTB/RIF as a substitute for SM obtained an ICER of 122.13USD/DALY averted. TB prevalence and risk of infection were the main factors impacting MODS and Xpert® MTB/RIF ICER in the one-way sensitivity analysis. In the probabilistic sensitivity analysis, Xpert® MTB/RIF was most likely to have an ICER below the WPT, whereas MODS was not. CONCLUSION: Our cost-utility analysis favours the implementation of Xpert® MTB/RIF as a replacement of SM for all TB suspects in this rural high TB/HIV prevalence African setting.

OBJECTIVE: In 2013, Mozambique adopted Option B+, universal lifelong antiretroviral therapy (ART) for all pregnant and lactating women, as national strategy for prevention of mother-to-child transmission of HIV. We analysed retention in care of pregnant and lactating women starting Option B+ in rural northern Mozambique. METHODS: We compared ART outcomes in pregnant ('B+ pregnant'), lactating ('B+ lactating') and non-pregnant non-lactating women of childbearing age starting ART according to clinical and/or immunological criteria ('own health') between July 2013 and June 2014. Lost to follow-up was defined as no contact >180 days after the last visit. Multivariable competing risk models were adjusted for type of facility (type 1 vs. peripheral type 2 health centre), age, WHO stage and time from HIV diagnosis to ART. RESULTS: Over 333 person-years of follow-up (243 'B+ pregnant', 65'B+ lactating' and 317 'own health' women), 3.7% of women died and 48.5% were lost to follow-up. 'B+ pregnant' and 'B+ lactating' women were more likely to be lost in the first year (57% vs. 56.9% vs. 31.6%; P < 0.001) and to have no follow-up after the first visit (42.4% vs. 29.2% vs. 16.4%; P < 0.001) than 'own health' women. In adjusted analyses, risk of being lost to follow-up was higher in 'B+ pregnant' (adjusted subhazard ratio [asHR]: 2.77; 95% CI: 2.18-3.50; P < 0.001) and 'B+ lactating' (asHR: 1.94; 95% CI: 1.37-2.74; P < 0.001). Type 2 health centre was the only additional significant risk factor for loss to follow-up. CONCLUSIONS: Retention among PLW starting option B+ ART was poor and mainly driven by early losses. The success of Option B+ for prevention of mother-to-child transmission of HIV in rural settings with weak health systems will depend on specific improvements in counselling and retention measures, especially at the beginning of treatment.

The objective of the present study was to assess the diagnostic accuracy of the microscopic observation drug susceptibility (MODS) assay for tuberculosis (TB) diagnosis in HIV-infected patients. MEDLINE, EMBASE, LILACS, the Cochrane Central Register of Controlled Trials, African Index Medicus, ResearchGate, SciELO, and the abstracts of the main conferences on infectious diseases and tropical medicine were searched, and other sources investigated. Only studies including HIV-infected patients evaluating MODS for the diagnosis of TB and using culture-based diagnostic tests as a gold standard were analysed. Summary sensitivity and specificity were calculated with a bivariate model. 3259 citations were found, 29 were selected for full-text review and 10 studies including 3075 samples were finally analysed. Overall diagnostic accuracy of MODS for the diagnosis of TB was a sensitivity of 88.3% (95% CI 86.18-90.2%) and specificity 98.2% (95% CI 97.75-98.55%). For multidrug-resistant (MDR)-TB, sensitivity was 89% (95% CI 66.07-97%) and specificity was 100% (95 CI 94.81-100%). For smear-negative pulmonary TB, a sensitivity of 88.2% (95% CI 86.1-89.9%) and specificity of 98.2% (95% CI 96.8-98.9%) were found. Costs varied between USD 0.72 and 7.31 per sample. Mean time to positivity was 8.24 days. MODS was found to have a good accuracy for the diagnosis of TB and MDR-TB in HIV-infected patients with low cost and fast results.

Strongyloidiasis is a widespread parasitic disease that can be life-threatening in immunosuppressed people. In the Mediterranean basin, autochthonous cases coexist with imported ones. We aimed to assess the utility of different screening methods, along with the frequency of strongyloidiasis and its associated risk factors in migrants and the native population. This cross-sectional study took place from 2019 to 2022 in the area of the Vega Baja Hospital in Alicante, Spain. Screening was performed in people who were immunosuppressed, at risk of immunosuppression, with blood asymptomatic eosinophilia, and in asymptomatic people from highly endemic countries. Screening methods were serological techniques (ELISA), stool parasitological tests (fecal concentration methods and agar plate culture), and a stool molecular test (PCR). Of the 168 participants (62.5% males, 53.0% migrants, 36.3% immunosuppressed, median age 57 years), 14 (8.3%) had confirmed strongyloidiasis, where 6 were confirmed by serology, 4 by PCR, and 4 by both methods. Overall, 9% of the migrants and 7.6% of the native-born patients were infected. Elevated IgE and hemoglobin and Latin American origin were associated with strongyloidiasis diagnosis. Screening with serology alone would have missed 28.6% of cases. We conclude that strongyloidiasis prevalence is high in our population, both in native and migrant groups, and stool PCR is a useful tool to increase case detection.
RESUMO
OBJECTIVE: Readmission for COVID-19 is associated with high mortality, saturation of health services, and high costs. This study aimed to assess the incidence and risk factors of readmissions in COVID-19 patients in a regional hospital of Spain from February 2020 to March 2021. METHODS: A retrospective cohort study describing the characteristics of adult patients readmitted within thirty days of discharge after being infected with SARS-CoV-2 was carried out. Readmission associated risk factors were analysed using a binary logistic regression model. RESULTS: Of the 967 patients who survived their first COVID-19 admission, 70 (7.2%) were readmitted within thirty days. Of these, 34.3% presented pneumonia progression, 15.7% functional deterioration, and 12.9% other infections. The mortality rate during readmission was 28.6%. There were no statistically significant differences in the cumulative incidence of readmissions between the epidemic periods (p=0.241). Factors independently associated with readmission were: diabetes mellitus (aOR 1.96, 95%CI 1.07-3.57, p=0.030); acute kidney failure (aOR 2.69, 95%CI 1.43-5.07, p=0.002); not being a candidate for intensive care (aOR 7.68, 95% CI 4.28-13.80, p<0.001); and not being prescribed corticosteroids at discharge (aOR 2.15, 95% CI 1.04-4.44; p=0.039). CONCLUSIONS: A substantial proportion of patients admitted due to COVID-19 are readmitted, and they carry a high letality. Diabetes mellitus, acute kidney failure, not being a candidate for ICU admission, and not being prescribed corticosteroids on discharge are independently associated with an increased risk of readmission.
OBJECTIVE: Los reingresos por la COVID-19 se asocian a un incremento de la mortalidad, saturación de los servicios sanitarios y elevados costes. Este estudio pretendió evaluar la incidencia y los factores de riesgo de reingreso en pacientes con COVID-19 en un hospital comarcal español entre febrero de 2020 y marzo de 2021. METHODS: Se realizó un estudio sobre una cohorte que describía las características de los pacientes adultos reingresados en los treinta días siguientes al alta tras un ingreso por la COVID-19. Se analizaron los factores de riesgo asociados a reingreso mediante un modelo de regresión de logística binaria. RESULTS: De los 967 pacientes dados de alta de un primer ingreso por la COVID-19, 70 (7,2%) reingresaron en los treinta días siguientes. De ellos, el 34,3% presentó progresión de la neumonía, el 15,7% deterioro funcional y el 12,9% otras infecciones. La letalidad en el reingreso fue del 28,6%. No hubo diferencias estadísticamente significativas en la incidencia acumulada de reingreso entre los tres periodos (p=0,241). Los factores asociados de forma independiente con el reingreso fueron: diabetes mellitus (ORa: 1,96; IC 95%:1,07-3,57; p=0,030); insuficiencia renal aguda (ORa 2,69; IC del 95%: 1,43-5,07, p=0,002); no ser candidato a cuidados intensivos (ORa 7,68, IC 95% 4,28-13,80, p<0,001); y no tener prescritos corticosteroides al alta (ORa 2,15, IC 95% 1,04- 4,44; p=0,039). CONCLUSIONS: Una proporción sustancial de los pacientes ingresados por la COVID-19 reingresan, con una elevada letalidad. La diabetes mellitus, la insuficiencia renal aguda, no ser candidato a ingreso en UCI y no tener prescritos corticoides al alta se asocian con un mayor riesgo de reingreso.

The Spanish Society of Tropical Medicine and International Health (SEMTSI), the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), the Spanish Society of Emergency Medicine (SEMES), the Spanish Society of Primary Care Physicians (SEMERGEN) and the Spanish Society of Family and Community Medicine (SEMFYC) have prepared a consensus statement on the diagnosis and management of patients with imported febrile illnesses. Twenty authors with different backgrounds and representing different healthcare perspectives (ambulatory primary care, travel and tropical medicine specialists, emergency medicine, hospital care, microbiology and parasitology and public health), identified 39 relevant questions, which were organised in 7 thematic blocks. After a systematic review of the literature and a thoughtful discussion, the authors prepared 125 recommendations, as well as several tables and figures to be used as a consulting tool. The present executive summary shows a selection of some of the most relevant questions and recommendations included in the guidelines.

A systematic screening for measles, mumps, rubella (MMR) and varicella zoster virus (VZV) in HIV-positive adult immigrants in Spain was evaluated, and factors associated with MMR and VZV vaccines' indication were studied. Every HIV-positive immigrant was tested for VZV and MMR-IgG. MMR vaccine was indicated to patients with lymphocytes CD4+ >200 cells/mm³ and a negative measles-IgG, a negative mumps-IgG and/or a negative rubella-IgG. VZV vaccine was indicated to every VZV-IgG negative patient with CD4+ >400 cells/mm³. In total, 289 patients were screened; seroprevalence was 95.2%, 92.2%, 70.3% and 89.3% for VZV, measles, mumps and rubella IgG, respectively. Having a negative VZV-IgG was statistically associated with coming from sub-Saharan Africa (prevalence ratio [PR]: 6.52; 95% CI: 1.71-24.84; p=0.006), while having secondary education was a protective factor (PR: 0.25; 95% CI: 0.07-0.97; p=0.045). Fourteen patients (4.8%) had indication of VZV vaccine; vaccination was feasible in 21.4% of them at first visit. Eighty-one patients (29.7%) had indication of MMR vaccine, most of them due to mumps-IgG negative (53.1%) or rubella-IgG negative (24.7%). Age < 30 years at first visit was the only factor statistically associated with MMR vaccine indication (PR: 1.47; 95% CI: 1.02-2.11; p=0.04). According to CD4+ cell counts, vaccination was feasible in 71.6% of patients at first visit. In conclusion, more than a third of HIV-infected immigrant patients are susceptible to at least one easily preventable infectious disease. Especial attention should be given to immigrant women of childbearing age.

BACKGROUND: Rickettsioses are emerging zoonotic diseases with worldwide prevalence, recognized as a cause of imported fever in travellers and migrants. Our objective is to describe the microbiological, clinical and epidemiological characteristics of imported rickettsioses in travellers and migrants included in a Spanish collaborative network database. METHODS: This multicentre retrospective observational study was nested in +Redivi, the Cooperative Network for the Study of Infections Imported by Immigrants and Travellers. We asked collaborating centres for microbiological, clinical and epidemiological data on the rickettsiosis cases from the inception of the network in 2009 to December 2020. RESULTS: Fifty-four cases of imported rickettsioses were included; 35 (64.8%) patients were men, and the median age was 37 years (interquartile range 26, 51.2). Only 7.4% of patients were travellers visiting friends and relatives, and 5.6% were migrants. The most frequent travel destination (38.9%) was South Africa, and 90.7% engaged in a high-risk activity. Twenty-seven patients (50.0%) started presenting symptoms after their return to Spain. The most frequent symptoms were febrile syndrome (55.6%) and cutaneous manifestations (27.8%). Most diagnoses (63.0%) were confirmed by serology. Only a few cases (9.3%) required hospitalization. All participants had a full recovery. CONCLUSIONS: Clinicians should suspect rickettsial diseases in travellers coming from high-risk areas, especially Southern Africa, who have engaged in activities in rural areas and natural parks. Doxycycline should be considered in the empiric treatment of imported fever of travellers coming from those areas or who have engaged in high-risk activities. There is a need to improve access to molecular diagnosis of rickettsiosis in Spain.

Introduction: The evidence for remdesivir therapy in immunocompromised patients is scarce. To evaluate remdesivir (RDV) effectiveness and safety in COVID-19 outpatients at high risk for progression in a real-world setting, we compare the outcome in immunocompromised (IC) patients with that in non-immunocompromised patients. Methods: Two hospitals conducted a retrospective study of all adult patients with mild-to-moderate SARS-CoV-2 infection at high risk for disease progression who were treated as outpatients with a 3-day course of RDV (1st January-30th September 2022). The primary effectiveness endpoint was a composite of any cause of hospitalization or death by day 30. A multiple logistic regression model was built to explore the association between immune status and clinical outcome, estimating adjusted odds ratios [aORs (95% CI)]. Results: We have included 211 patients, of which 57% were males, with a median age of 65 years (IQR 53-77), 70.1% were vaccinated (three or four doses), and 61.1% were IC. The median duration of symptoms before RDV treatment was 3 days (IQR 2-5). During follow-up, 14 (6.6%) patients were hospitalized, of which 6 (2.8%) were hospitalized for COVID-19 progression. No patient required mechanical ventilation, and two patients died (non-COVID-19-related). After accounting for potential confounders, only anti-CD20 treatment was associated with the composed outcome [aOR 5.35 (1.02-27.5, 95% CI)], whereas the immunocompetence status was not [aOR 1.94 (0.49-7.81, 95% CI)]. Conclusion: Early COVID-19 outpatient treatment with a 3-day course of remdesivir in vaccinated patients at high risk for disease progression during the Omicron surge had a good safety profile. It was associated with a low rate of all-cause hospitalization or death, regardless of immunocompetence status.
RESUMO
INTRODUCTION: There is negligible evidence on the efficacy of ivermectin for treating COVID-19 pneumonia. This study aimed to assess the efficacy of ivermectin for pre-emptively treating Strongyloides stercoralis hyperinfection syndrome in order to reduce mortality and the need for respiratory support in patients hospitalized for COVID-19. METHODS: This single-center, observational, retrospective study included patients admitted with COVID-19 pneumonia at Hospital Vega Baja from 23 February 2020 to 14 March 2021. Because strongyloidiasis is endemic to our area, medical criteria support empiric administration of a single, 200 µg/kg dose of ivermectin to prevent Strongyloides hyperinfection syndrome. The outcome was a composite of all-cause in-hospital mortality and the need for respiratory support. RESULTS: Of 1167 patients in the cohort, 96 received ivermectin. After propensity score matching, we included 192 patients. The composite outcome of in-hospital mortality or need for respiratory support occurred in 41.7% of the control group (40/96) and 34.4% (33/96) of the ivermectin group. Ivermectin was not associated with the outcome of interest (adjusted odds ratio [aOR] 0.77, 95% confidence interval [CI] 0.35, 1.69; p = 0.52). The factors independently associated with this endpoint were oxygen saturation (aOR 0.78, 95% CI 0.68, 0.89, p < 0.001) and C-reactive protein at admission (aOR: 1.09, 95% CI 1.03, 1.16, p < 0.001). CONCLUSIONS: In hospitalized patients with COVID-19 pneumonia, ivermectin at a single dose for pre-emptively treating Strongyloides stercoralis is not effective in reducing mortality or the need for respiratory support measures.

INTRODUCTION: The number of HIV-positive immigrants have increased in Spain in the last few years, and now represent a significant proportion of the epidemic. Our objective is to describe the clinico-epidemiological characteristics of HIV-positive immigrants seen in a specialist unit in Madrid. MATERIAL AND METHODS: Retrospective study. Every patient born in a country other than Spain and attended an HIV Unit in Madrid between 1992 and 2009 was included. RESULTS: Of the 371 patients included, 53.1% were Latin Americans, 24.5% Sub-Saharan Africans, and 22.4% others), and 60% were males. Immigrants represented 0.3% of new patients in 1992 and rose to 49.2% in 2009. The principal reason for HIV testing had been pregnancy/delivery among women (32.7%) and having a category-B disease among men (17.4%). Sexual transmission accounted for 92% of patients. Tuberculosis was the principal AIDS-diagnosing illness. Respectively 90%, 7.7%, 60%, 26.7%, 96% and 95% of patients had an IgG for HAV, HCV, Toxoplasma, Treponema, CMV and VZV. VHB-Ags+: 5.4%; PPD+: 17%. At least one syphilis episode was recorded in 62% of the men who have sex with men (MSM). Prevalence of HLA-B5701 was 6%, 0.9% and 3.8% in Caucasians, Amerindians and Afro-Americans, respectively. CONCLUSIONS: Immigrants represent a significant proportion of new HIV-positive patients. It is a very heterogeneous group according to their clinical and epidemiological characteristics.

BACKGROUND: There are few reports of imported fascioliasis in Spain. This study aimed to describe the characteristics of cases registered in +REDIVI network. METHODS: Observational, retrospective, descriptive study of imported fascioliasis cases registered in the +REDIVI, a multicenter collaborative network collecting information on imported infectious diseases in Spain, from October 2009 to May 2019. RESULTS: Of 25,203 cases of imported disease registered over the study period, 16 (0.063%) were fascioliasis, acquired mainly in Pakistan, Morocco, Bolivia, and Peru. Clinical, analytical, and therapeutic data were available for 12 cases (6 immigrants, 4 people visiting friends and relatives, 2 travelers). Eleven (91.6%) had eosinophilia. The most frequent symptoms were abdominal pain (n = 5) and cough (n = 5). Two cases (16.66%) were acute and 10 (83.33%) chronic. Two patients presented lung involvement, and four had other parasitic co-infections. Twelve cases (100%) were seropositive for Fasciola hepatica. Ten patients underwent a coproparasitological study, none of which detected Fasciola spp. eggs. The probable food origin (watercress) was confirmed in 3 cases (25%). Nine of the 10 patients treated with triclabendazole (90%) and one patient treated with praziquantel were considered to meet the criteria for cure. One patient was lost to follow-up. CONCLUSIONS: Fascioliasis is a rare imported parasitosis in Spain. Eosinophilia, along with geographical origin, is the main clue for diagnosis.

BACKGROUND: Etiological diagnosis of febrile illnesses in returning travelers is a great challenge, particularly when presenting with no focal symptoms [acute undifferentiated febrile illnesses (AUFI)], but is crucial to guide clinical decisions and public health policies. In this study, we describe the frequencies and predictors of the main causes of fever in travelers. METHODS: Prospective European multicenter cohort study of febrile international travelers (November 2017-November 2019). A predefined diagnostic algorithm was used ensuring a systematic evaluation of all participants. After ruling out malaria, PCRs and serologies for dengue, chikungunya and Zika viruses were performed in all patients presenting with AUFI ≤ 14 days after return. Clinical suspicion guided further microbiological investigations. RESULTS: Among 765 enrolled participants, 310/765 (40.5%) had a clear source of infection (mainly traveler's diarrhea or respiratory infections), and 455/765 (59.5%) were categorized as AUFI. AUFI presented longer duration of fever (p < 0.001), higher hospitalization (p < 0.001) and ICU admission rates (p < 0.001). Among travelers with AUFI, 132/455 (29.0%) had viral infections, including 108 arboviruses, 96/455 (21.1%) malaria and 82/455 (18.0%) bacterial infections. The majority of arboviral cases (80/108, 74.1%) was diagnosed between May and November. Dengue was the most frequent arbovirosis (92/108, 85.2%). After 1 month of follow-up, 136/455 (29.9%) patients with AUFI remained undiagnosed using standard diagnostic methods. No relevant differences in laboratory presentation were observed between undiagnosed and bacterial AUFI. CONCLUSIONS: Over 40% of returning travelers with AUFI were diagnosed with malaria or dengue, infections that can be easily diagnosed by rapid diagnostic tests. Arboviruses were the most common cause of AUFI (above malaria) and most cases were diagnosed during Aedes spp. high season. This is particularly relevant for those areas at risk of introduction of these pathogens. Empirical antibiotic regimens including doxycycline or azithromycin should be considered in patients with AUFI, after ruling out malaria and arboviruses.

Strongyloidiasis is a parasitic infection distributed worldwide, with an estimated 614 million people infected. Strongyloidiasis usually presents asymptomatically or with aspecific and mild clinical symptoms, mainly cutaneous, respiratory, or gastrointestinal. Disseminated disease and hyperinfection syndrome are the most serious complications, have a high mortality rate, usually occur in immunosuppressed patients, and are particularly associated with the use of corticosteroids. Strongyloidiasis is the most neglected of the neglected diseases, and its occurrence in pregnancy has been neglected and understudied. In this review, we focus on the effects of strongyloidiasis during pregnancy and highlight the knowledge shortage and the need for more research on the subject. There are few studies addressing strongyloidiasis prevalence during pregnancy and hyperinfection incidence during pregnancy is practically unknown, with only isolated case reports published. Although data are scarce, the infection has been associated with developmental disabilities and anemia during pregnancy, while hyperinfection may cause both maternal and neonatal death. Data on the best screening and diagnostic strategies during pregnancy are lacking. There is insufficient evidence on ivermectin safety in pregnancy, complicating treatment recommendations.
