Protocol for the systematic review of the Pneumocystis jirovecii-associated pneumonia in non-HIV immunocompromised patients.

Pneumocystis jirovecii pneumonia (PJP) is a well-known and frequent opportunistic infection in HIV patients. However, there has been an increase in the number of reports of PJP in other immunosuppressed patients with autoimmune inflammatory disorders or because of chemotherapy and high doses of steroids, especially when used in combination as part of immunosuppressive therapy. Despite the increasing importance of PJP in non-HIV patients, there is a lack of comprehensive and updated information on the epidemiology, pathogenesis, diagnosis, microbiology, treatments, and prophylaxis of this infection in this population. Therefore, the objective of this systematic review is to synthesize information on these aspects, from a perspective of evidence-based medicine. The protocol is prepared following the preferred reporting items for systematic reviews and meta-analyses (PRISMA-P) guidelines. We will perform a systematic review of literature published between January 2010 and July 2023, using the databases PubMed, Google Scholar, ScienceDirect, and Web of Science. In addition, manual searches will be carried out through related articles, and references to included articles. The main findings and clinical outcomes were extracted from all the eligible studies with a standardized instrument. Two authors will independently screen titles and abstracts, review full texts, and collect data. Disagreements will be resolved by discussion, and a third reviewer will decide if there is no consensus. We will synthesize the results using a narrative or a meta-analytic approach, depending on the heterogeneity of the studies. It is expected that this systematic review will provide a comprehensive and up-to-date overview of the state-of-the-art of PJP in non-HIV patients. Furthermore, the study will highlight possible gaps in knowledge that should be addressed through new research. Here, we present the protocol for a systematic review which will consider all existing evidence from peer-reviewed publication sources relevant to the primary and secondary outcomes related to diagnosing and managing PJP in non-HIV patients.

Overview of acute liver failure in India.

Acute liver failure (ALF) is an infrequent, but serious complication subsequent to severe acute liver injury (sALI) due to various hepatotoxic agents such as hepatotropic virus(es) and drugs such as anti-tubercular medications, paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics and anti-cancer and anti-epileptic therapy and due to metabolic and autoimmune disease flares. ALF after sALI presents with encephalopathy associated with prolonged international normalized ratio (INR). Mortality in ALF is high and ranges between 50% and 80%. Due to severe liver damage, multiple sequels consequent to hepatic dysfunction result in complications such as hyperammonemia that culminates in encephalopathy associated with cerebral edema; innate immune paralysis resulting in increased frequency of infections and endotoxemia causing decrease in systemic vascular resistance (SVR) and tissue hypoperfusion and damage-associated molecular patterns (DAMPs) released from damaged hepatic parenchyma inducing pro-inflammatory cytokine storm, which may cause other organ dysfunctions. Certain etiologies such as hepatitis E virus and hepatitis A virus-related ALF or paracetamol-ALF (hyper-acute presentation) have better survival than remaining causes. In addition, if etiology-specific treatment (antivirals for ALF related to hepatitis B virus (HBV) or Herpes simplex virus (HSV) or N-acetylcysteine for paracetamol) is available, then the outcome with treatment is better. About half of the patients can be salvaged with medical therapy. All patients need intensive care and organ support to provide time for the liver to regenerate. Various prognostic models to predict high probability of mortality have been described, which should be used to select patient early during the disease for liver transplantation, which is associated with high long-term survival in these sick patients. The Indian National Association for Study of the Liver (INASL) recommends the ALF-Early Dynamic (ALFED) model as a preferred prognostic model in the Indian scenario, where hepatitis viruses are a dominant etiology of ALF and occur on a naïve liver with good regenerative capacity.

Retrospective Genotyping of Enteroviruses Using a Diagnostic Nanopore Sequencing Workflow

Enteroviruses are among the most common viruses pathogenic to humans. They are associated with various forms of disease, ranging from mild respiratory illness to severe neurological diseases. In recent years, an increasing number of isolated cases of children developing meningitis or encephalitis as a result of enterovirus infection have been reported, as well as discrete enterovirus D68 outbreaks in North America in 2014 and 2016. We developed an assay to rapidly genotype enteroviruses by sequencing a region within the VP1 gene using nanopore Flongles. We retrospectively analyzed enterovirus-/rhinovirus-positive clinical samples from the Zurich, Switzerland area mainly collected during two seasons in 2019/2020 and 2021/2022. Respiratory, cerebrospinal fluid, and stool samples were analyzed. Whole-genome sequencing was performed on samples with ambiguous genotyping results and enterovirus D68-positive samples. Out of 255 isolates, a total of 95 different genotypes were found. A difference in the prevalence of enterovirus and rhinovirus infections was observed for both sample type and age group. In particular, children aged 0–4 years showed a higher frequency of enterovirus infections. Comparing the respiratory seasons, a higher prevalence was found, especially for enterovirus A and rhinovirus A after the SARS-CoV-2 pandemic. The enterovirus genotyping workflow provides a rapid diagnostic tool for individual analysis and continuous enterovirus surveillance.

Insights into phage-bacteria interaction in cold seep Gigantidas platifrons through metagenomics and transcriptome analyses

Viruses are crucial for regulating deep-sea microbial communities and biogeochemical cycles. However, their roles are still less characterized in deep-sea holobionts. Bathymodioline mussels are endemic species inhabiting cold seeps and harboring endosymbionts in gill epithelial cells for nutrition. This study unveiled a diverse array of viruses in the gill tissues of Gigantidas platifrons mussels and analyzed the viral metagenome and transcriptome from the gill tissues of Gigantidas platifrons mussels collected from a cold seep in the South Sea. The mussel gills contained various viruses including Baculoviridae, Rountreeviridae, Myoviridae and Siphovirdae, but the active viromes were Myoviridae, Siphoviridae, and Podoviridae belonging to the order Caudovirales. The overall viral community structure showed significant variation among environments with different methane concentrations. Transcriptome analysis indicated high expression of viral structural genes, integrase, and restriction endonuclease genes in a high methane concentration environment, suggesting frequent virus infection and replication. Furthermore, two viruses (GP-phage-contig14 and GP-phage-contig72) interacted with Gigantidas platifrons methanotrophic gill symbionts (bathymodiolin mussels host intracellular methanotrophic Gammaproteobacteria in their gills), showing high expression levels, and have huge different expression in different methane concentrations. Additionally, single-stranded DNA viruses may play a potential auxiliary role in the virus–host interaction using indirect bioinformatics methods. Moreover, the Cro and DNA methylase genes had phylogenetic similarity between the virus and Gigantidas platifrons methanotrophic gill symbionts. This study also explored a variety of viruses in the gill tissues of Gigantidas platifrons and revealed that bacteria interacted with the viruses during the symbiosis with Gigantidas platifrons. This study provides fundamental insights into the interplay of microorganisms within Gigantidas platifrons mussels in deep sea.

Seroprevalence of Herpes Simplex Virus Types 1 and 2 among Pregnant Women in South-Western Romania

Background: Pregnancy-related infections with the human herpes simplex virus (HSV) strains HSV-1 and HSV-2 are particularly noteworthy. There are numerous reported examples of intrapartum transmission of herpes infection, notwithstanding the extreme rarity of intrauterine transfer from mother to fetus. The purpose of this study was to evaluate the seroprevalence of HSV-1 and HSV-2 antibodies in pregnant women in the western region of Romania. Methods: Pregnant women who presented for routine pregnancy monitoring at Romania’s County Clinical Emergency Hospital in Craiova between 2013 and 2016 and 2019 and 2022 were included in the study. In order to find anti-HSV-1/2 IgG antibodies, we conducted serological testing on the patients and gathered demographic information from them. Results: HSV-1 seroprevalence was shown to have declined in rural areas and increased in urban areas, with values between 2013 and 2016 being 89.30% and those between 2019 and 2022 being 84.96%, respectively. Women over 35 who were pregnant had the highest seroprevalence. The seroprevalence of HSV-2 decreased from 16.16% in 2013–2016 to 12.43% in 2019–2022, and both rural and urban areas continued to experience this declining trend. Similarly, pregnant women over 35 years old had the highest frequency of HSV-1 infections. Conclusions: Establishing educational programs and other actions to reduce the transmission rate and ultimately the prevalence of the disease can be made easier with knowledge about the seroprevalence of HSV-1 and HSV-2 infections.

Differences between radiographic and non-radiographic axial spondyloarthritis patients in a Mexican cohort

To compare the demographic, clinical, and laboratory characteristics, disease onset, and clinical features of radiographic axial Spondyloarthritis (r-axSpA) and non-radiographic axial Spondyloarthritis (nr-axSpA) patients. All patients who attended outpatient spondylarthritis (SpA) clinics at Hospital General de Mexico and the Instituto Nacional de la Nutrición from 1998 to 2005 and met the rheumatologist diagnostic criteria for SpA were selected. Then the SpA patients were classified by European Spondyloarthropathy Study Group criteria (ESSG). We selected SpA patients with axial presentation as axial SpA (axSpA), and they were classified as r-axSpA if they met modified New York (mNY) criteria for sacroiliitis and as nr-axSpA if they did not meet mNY criteria; to compared clinical, demographic, and laboratory test between the subgroups. It included 148 SpA patients; 55 (37.2%) patients had r-axSpA, and 70 (47.3%) had nr-axSpA. The nr-axSpA patients had a lower proportion of males (58.6% vs 78.2%, P < 0.05), lower HLA-B27 frequency (54.3%. vs. 92.7%, P < 0.05), were older at disease onset (21 vs 16 years; P < 0.01) and had a higher frequency of infections at disease onset (9.1% vs 32.9, P < 0.05) than r-axSpA. BASFI (2.9 vs 4.8; P < 0.0001), Dougados functional index (7 vs. 14; P < 0.05), and BASDAI (4.1 vs. 5.2; P < 0.001) were lower in patients with nr-axSpA than r-axSpA, respectively. The factors that most influenced the presentation of r-axSpA were history of uveitis (OR 14, 95% CI 2.3–85), HLA-B27 (OR 7.97, 95% CI, 2.96–122), male sex (OR 6.16, 95% CI, 1.47–25.7), axial enthesopathy count (OR 1.17 95% CI, 1.03–1.33). This study provides insight into the differences between nr-axSpA and r-axSpA in Mexico. Patients with r-axSpA were mainly male, with a younger presentation age, a higher prevalence of HLA-B27, more history of uveitis, fewer episodes of dactylitis, more axial enthesopathy, and higher disease activity than nr-axSpA.

Navigating a complex case of Mycobacterium xenopi in a patient with blue rubber bleb nevus syndrome

Introduction: Blue rubber bleb nevus syndrome is a rare disorder of venous malformations, with around 200 cases reported. We present a case of Mycobacterium xenopi infection in a patient with blue rubber bleb nevus syndrome. Case Description: A 40-year-old female with blue rubber bleb nevus syndrome, asthma, and bronchiectasis came to the pulmonology clinic with shortness of breath and a cough. She was recently admitted for a bronchiectasis exacerbation but continued to have a worsening productive cough and fevers. The most recent CT scan of the chest showed interval stable right upper lobe fibrocavitary disease, demonstrating gradual progression over two years. She had occasional positive cultures for Mycobacterium Avium Complex and M. xenopi one year previously, assumed to be a colonizer and not treated. Most recent hospital cultures were negative for bacteria and an acid-fast bacilli smear. She was sent to the emergency department for bronchiectasis exacerbation and returned to the clinic six weeks later with two sputum cultures growing M. xenopi. It was decided to treat M. xenopi as this was likely the cause of her cavitary lung lesion and frequent infections. Azithromycin, rifampin, and sulfamethoxazole/trimethoprim were initiated. Intravenous amikacin was added later on. She finally had a right partial lung resection done after one year at an outside hospital. She was on and off antibiotics for M. xenopi for approximately three years with negative repeat cultures for non-tuberculous mycobacteria. Conclusion: Due to the high mortality of M. xenopi infections (which can be as high as 69%), treatment of at least twelve months is recommended. To our knowledge, this is the first reported case of M. xenopi in a patient with blue rubber bleb nevus syndrome.

On the Possibility of Using the Topical form of the Recombinant Interferon alpha-2b Drug in the Prevention of Acute Respiratory Viral Infections in Organized Groups

Relevance. Respiratory infections are an urgent problem for organized groups, including military ones, since the transmission of pathogens by airborne droplets and household contact routes, physical and psychological stress on adaptive mechanisms contribute to the development of the epidemic process. There is no doubt that vaccination makes a significant contribution to the prevention of respiratory infections, but the contingent remains vulnerable to other pathogens against which there are no vaccines. Therefore, the search for new methods of non-specific prevention is necessary in maintaining the health of persons permanently residing in collectives. Aim. Evaluation of the possibility of using the topical form of the recombinant interferon α-2b drug for the prevention of acute respiratory viral infections in organized groups. Materials and methods. The work was carried out according to the methodology of a multicenter (3 Centers) double-blind controlled trial involving 3,235 people aged 18 to 22 years, who were divided into three groups: 1 gy. - received a recombinant interferon α-2b (Grippferon) drug 3 drops in each nasal passage 2 times a day in for two weeks; 2 g. - saline solution intranasally according to the same scheme; 3 g. - the volunteers did not receive anything. The frequency of respiratory infections was studied. Results and discussion. Medical monitoring of the study participants, which was carried out for 2 months, showed that in the groups from the Center 1, the incidence of acute respiratory diseases for 2 months in the main group (gr. 1) was 2.3 times lower than in the control (gr. 2) and the comparison group (gr. 3). In the Center 2 The data corresponded to the dynamics of Center 1: the incidence values were 2.4-2.5 times lower in Group 1. In Center 3, the values were 2.0-2.1, respectively. The epidemic effect of intranasal administration of the topical form of the drug recombinant interferon α-2b is due to its effect on the factors of mucosal immunity, which contributes to non-specific protection and increased body resistance against respiratory infections. Conclusions. The presented advantages of the recombinant interferon α-2b drug make it possible to draw attention to the clinical feasibility of its use for preventive purposes in organized groups, including military ones, from the position of high epidemiological effectiveness, both pre-exposure and post-exposure prevention of acute respiratory viral infections.

ADLM Guidance Document on Laboratory Diagnosis of Respiratory Viruses.

Respiratory viral infections are among the most frequent infections experienced worldwide. The COVID-19 pandemic has highlighted the need for testing and currently several tests are available for the detection of a wide range of viruses. These tests vary widely in terms of the number of viral pathogens included, viral markers targeted, regulatory status, and turnaround time to results, as well as their analytical and clinical performance. Given these many variables, selection and interpretation of testing requires thoughtful consideration. The current guidance document is the authors' expert opinion based on the preponderance of available evidence to address key questions related to best practices for laboratory diagnosis of respiratory viral infections including who to test, when to test, and what tests to use. An algorithm is proposed to help laboratories decide on the most appropriate tests to use for the diagnosis of respiratory viral infections.

Managing children with frequent respiratory infections and associated wheezing: a preliminary randomized study with a new multicomponent nasal spray.

Preschoolers frequently have respiratory infections (RIs), which may cause wheezing in some subjects. Type 2 polarization may favor increased susceptibility to RIs and associated wheezing. Non-pharmacological remedies are garnering increasing interest as possible add-on therapies. The present preliminary study investigated the efficacy and safety of a new multi-component nasal spray in preschoolers with frequent RIs and associated wheezing. Some preschoolers with these characteristics randomly took this product, containing lactoferrin, dipotassium glycyrrhizinate, carboxymethyl-beta-glucan, and vitamins C and D3 (Saflovir), two sprays per nostril twice daily for 3 months. Other children were randomly treated only with standard therapy. Outcomes included the number of RIs and wheezing episodes, use of medications, and severity of clinical manifestations. Preschoolers treated add-on with this multicomponent product experienced fewer RIs and used fewer beta-2 agonists than untreated children (P = 0.01 and 0.029, respectively). This preliminary study demonstrated that a multicomponent product, administered add-on as a nasal spray, could reduce the incidence of RIs and use of symptomatic drugs for relieving wheezing in children.

Stunting and its associated factors among children living with HIV/AIDS: a cross-sectional study.

Growth failure is a common feature of children living with HIV/AIDS. This study was intended to assess the level of stunting and its associated factors among children living with HIV/AIDS. An institution-based cross-sectional study was conducted among 218 children living with HIV/AIDS. An interviewer-administered data collection tools and anthropometric measurements were used to collect data. Bivariable and multivariable logistic regression analyses were used to identify independent variables. Adjusted odds ratio with a 95% CI at a P value of 0.05, which was considered to declare statistical significance. The level of stunting among children infected with HIV/AIDS in selected northwest comprehensive specialized hospitals in western Amhara was 56.9%. Poor anti-retroviral therapy (ART) adherence [adjusted odds ratio (AOR)=6.15, 95% CI, (3.88-9.69)], lack of co-trimoxazole prophylaxis [AOR=2.0, 95% CI, (1.88-2.98)], opportunistic infection [AOR=4.66, 95% CI, (3.24-6.11), and feeding twice [AOR=3.88, 95% CI, (1.94-5.14)] and feeding three times [AOR=1.52, 95% CI, (1.23-3.89)] were significantly associated with stunting. Stunting among HIV/AIDS-infected children was very high. Poor ART adherence, lack of co-trimoxazole prophylaxis, opportunistic infection, and low feeding frequency were significantly associated to stunting among HIV/AIDS-infected children. Strategies need to be devised to address factors amenable to modification to improve the growth of children living with HIV/AIDS.

Impact of Booster Vaccination Interval on SARS-CoV-2 Infection, Hospitalization, and Death

ObjectivesWe investigated how booster interval affects the risks of SARS-CoV-2 infection and Covid-19-related hospitalization and death in different age groups. MethodsWe collected data on booster receipts and Covid-19 outcomes between September 22, 2021 and February 9, 2023 for 5,769,205 North Carolina residents ≥12 years of age who had completed their primary vaccination series. We related Covid-19 outcomes to baseline characteristics and booster doses through Cox regression models. ResultsFor adults ≥65 years of age, boosting every 9 months was associated with proportionate reductions (compared with no boosting) of 18.9% (95% CI, 18.5 to 19.4) in the cumulative frequency of infection, 37.8% (95% CI, 35.3 to 40.3) in the cumulative risk of hospitalization or death, and 40.9% (95% CI, 37.2 to 44.7) in the cumulative risk of death at two years after completion of primary vaccination. The reductions were lower by boosting every 12 months and higher by boosting every 6 months. The reductions were smaller for individuals 12–64 years of age. ConclusionBoosting at a shorter interval was associated with a greater reduction in Covid-19 outcomes, especially hospitalization and death. Frequent boosting conferred greater benefits for individuals aged ≥65 than for individuals aged 12–64.

Molecular characterization and host reaction to tomato mottle mosaic virus isolated from sweet pepper seeds in Japan.

Many countries have identified tomato mottle mosaic virus (ToMMV) as a serious threat to tomato production. Here, we constructed and characterized infectious clones of ToMMV isolated from Japanese sweet pepper seeds. The genome of the Japanese isolate is 6399 nucleotides in length and exhibits thehighest identity withpreviously characterized isolates. For example, it is 99.7% identical to that of the Mauritius isolate, which occurs worldwide. Phylogenetic analysis based on complete genome sequences revealed that the Japanese isolates clustered in the same clade as those from other countries. When homozygous tomato cultivars with tobamovirus resistance genes were inoculated with an infectious cDNA clone of ToMMV, the virus systemically infected tomato plants with symptoms typical of Tm-1-carrying tomato cultivars. In contrast, tomato cultivars carrying Tm-2 or Tm-22 showed symptoms only on the inoculated leaves. Furthermore, when commercial cultivars of Tm-22 heterozygous tomato were inoculated with ToMMV, systemic infections were observed in all cultivars, with infection frequencies ranging from 25 to 100%. Inoculation of heterozygous sweet pepper cultivars with tobamovirus resistance genes (L1, L3, and L4) with ToMMV resulted in an infection frequency of about 70%, but most of the infected L1, L3, and L4 cultivars were symptomless, and 10-20% showed symptoms of necrosis and yellowing. Tomato mosaic virus strain L11A, an attenuated virus, did not provide cross-protection against ToMMV and led to systemic infection with typical symptoms. These results suggest that ToMMV might cause extensive damage to existing tomato and sweet pepper cultivars commonly grown in Japan.

Molecular detection of intestinal parasites in a rural community of Colombia: A one health approach to explore potential environmental-zoonotic transmission.

Protozoan and helminth parasitic infections pose significant public health challenges, especially in developing countries with rural populations marked by suboptimal hygiene practices and socio-economic constraints. The parasites are the etiological agents of these infections and have a notably elevated global prevalence. Therefore, this study focuses on estimating the frequency and transmission dynamics of several parasitic species, including Blastocystis, Giardia, Cryptosporidium spp., Entamoeba histolytica, Ascaris lumbricoides, Trichuris trichiura, Taenia spp. and hookworms, within a rural community in southwest Colombia with a particular emphasis on the One Health framework, considering environmental and zoonotic transmission potentials. This study involved the analysis of 125 samples, encompassing human participants (n = 99), their domestic pets (dogs) (n = 24) and water sources (n = 2). Parasite detection was carried out utilizing a combination of microscopy and molecular techniques. Furthermore, the characterization of Blastocystis subtypes (STs) was achieved through Oxford Nanopore sequencing of the rRNA-18S gene. The investigation also entailed the examination of potential associations between intestinal parasitism and various sociodemographic factors. Results revealed a high frequency of parasitic infections when employing molecular methods, with Blastocystis (n = 109/87%), Giardia (n = 20/16%), Ancylostoma duodenale (n = 28/22%), Ancylostoma ceylanicum (n = 7/5.6%), E. histolytica (n = 6/4.8%), Cryptosporidium spp. (n = 12/9.6%) and even Taenia (n = 1/0.8%) detected. Cryptosporidium spp. was also identified in water samples. Coinfections were prevalent, with 57% (n = 70) of samples exhibiting single-parasite infections and 43% (n = 53) showing various degrees of polyparasitism, emphasizing the complexity of transmission dynamics. Blastocystis subtyping, conducted via Oxford Nanopore sequencing, revealed a diversity of subtypes and coexistence patterns, with ST2 being the most prevalent. This research underscores the importance of using molecular techniques for frequency estimation, particularly emphasizing the relevance of zoonotic transmission in parasitic infections. It highlights the significance of the One Health approach in comprehending the circulation of parasites among animals, humans and environmental sources, thereby directly impacting public health and epidemiological surveillance.

Narrative review of immediate salvage for penile prosthesis infection.

Implantation of a penile prosthesis is a reliable option for men with erectile dysfunction (ED) refractory to less invasive therapies. While the frequency of penile prosthesis infections have decreased, they remain a devastating complication. Herein we discuss why immediate salvage surgery is an essential technique for the management of implant infections. We will also describe the relevant advancements to this technique. We conducted a narrative review via computer based search of PubMed for all relevant articles on penile prosthesis infection management, including guidelines, case series, reviews, and expert opinions. Search terms used included: "inflatable penile prosthesis", "IPP", "penile prosthesis", "salvage", "treatment", "delayed", "immediate". Only English peer-reviewed publications were included. Historically, patients who presented with penile prosthesis infections were exclusively managed with complete removal of the prosthesis without replacement. Although this strategy is safe, it hastens immediate ED and corporal fibrosis, resulting in loss of penile length and increased difficulty with subsequent prosthesis replacement. Previous case series have reported successful treatment of localized penile prosthesis infections with nonsurgical treatment, but the role of conservative treatment remains limited. The current standard of immediate salvage entails removal of the infected prosthesis and washout followed by immediate replacement with a new penile prosthesis. This technique has been demonstrated to be safe and effective, thus allowing patients to resume intercourse and maintain penile length. Immediate salvage surgery is safe and effective, and has emerged as the preferred strategy for the management of most patients with a penile prosthesis infection.

Acceptance to take COVID-19 vaccine and its relation to COVID-19 infection

One of the biggest global health threats is vaccine hesitancy and it remains a global issue. The speed at which vaccines are developed and media misinformation contribute to vaccine reluctance. This study examined the relationship between vaccine acceptance and COVID-19 infection. A cross-sectional study was used with a sample of 1388 subjects including students and academic staff. Data were collected using the self-administered COVID-19 Vaccine Acceptance Behavior questionnaire, which has nine dimensions and 42 items and asks about COVID-19 infection frequency and timing. The mean COVID-19 vaccine behavior scores of hesitant subjects were low. Low trust in COVID-19 vaccines (25.4%) was the main reason for hesitancy. COVID-19 vaccine hesitancy is positively correlated with increased infection rates (P≤0.001). Acceptance of the COVID-19 vaccine can reduce infection rates, protect vulnerable populations, and aid public health efforts to control the virus.

CARRIERSHIP OF ANTI-TOXOCARA IGG ANTIBODIES AMONG PATIENTS WITH CLINICAL ALLERGY

Introduction: Toxocariasis is a zoonotic helminthosis caused by nematodes of the Toxocara genus. Humans are accidental hosts for the parasite. As Toxocara larvae migrate throughout the organism, they lead to the formation of allergic reactions. Purpose: Our goal is to study the connection between clinical allergy and toxocariasis by examining the frequency of infection with Toxocara spp. and the levels of anti-Toxocara IgG antibodies in patients with acute urticaria, chronic urticaria and other forms of allergic reactions. Materials and methods: Between 2018 and 2023, we tested 310 allergic patients serologically for anti-Toxocara IgG antibodies via the ELISA method. In addition we also tested 47 non-allergic people as a control group. Results: In our study, we detected anti-Toxocara IgG antibodies in 25,48% of allergic patients. We found that patients with allergy were statistically more likely to be seropositive for anti-Toxocara antibodies compared to the control group. We did not find any significant difference in the levels of antibodies between different types of allergic reactions. Conclusion: Our results show the need for serological testing for toxocariasis in all allergic patients. Additional methods and/or diagnostic markers are needed for proper assessment of cases and whether treatment is necessary.

Promoting penicillin allergy de-labeling for children attending a hematology clinic.

Up to 10% of children are reported to be allergic to penicillin, but many allergy labels are unverified and may require formal testing. Inaccurate drug allergy labels are associated with a range of adverse clinical outcomes. Patients with hematological disorders may experience frequent and severe infections; those who have been incorrectly labeled penicillin allergic may benefit from allergy de-labeling (ADL) efforts to facilitate access to beta-lactam antibiotics. We developed a multidisciplinary, pharmacist-driven process that enabled non-allergist trained providers to assess and de-label penicillin allergies in a pediatric hematology center. Volunteers, including physicians, advanced practice providers, nurses, and pharmacists, were trained in skin testing and oral challenge procedures. Patients were identified by review of electronic medical records for penicillin or penicillin-derivative allergy. Patient and family interviews were conducted in cases where a true penicillin allergy was deemed uncertain based on chart review. If allergy could not be de-labeled by chart review or interview alone, patients were offered skin and/or oral challenge testing. Fifty-nine patients were initially labeled as penicillin allergic. Allergy labels of 11 (19%) were removed by chart review only, and 15 (25%) after conducting interviews. A total of two (3%) patients were ineligible due to contraindications, and five (9%) declined participation. Twenty-six patients (44%) underwent allergy testing (50% skin testing, 50% oral challenge) of which 23 (88%) were negative. ADL was possible in most patients previously identified as penicillin allergic. Testing was well tolerated with no serious adverse effects.

Frequency of infections during rituximab treatment of autoimmune blistering diseases.

This study investigates the frequency of infections in autoimmune blistering disease (AIBD) patients treated with rituximab and evaluates the difference in infectious complications in patients on concomitant antibiotic and/or antiviral prophylaxis. The study retrospectively reviewed 43 AIBD patients who received rituximab over a five-year interval. The patients were categorized based on prophylaxis type (antibiotic, antiviral, or both) and concomitant immunosuppression status, which we defined as treatment with an immunosuppressive medication during the time frame they were given Rituximab. Our findings suggest that concomitant immunosuppression alongside rituximab did not significantly increase the risk of developing infectious complications compared to rituximab monotherapy. Results revealed that 34.4% of patients with concomitant immunosuppression had a secondary bacterial infection, defined as bacterial complications requiring hospitalization, consistent with prior studies. Moreover, antibiotic prophylaxis did not significantly reduce infection risk in patients on rituximab, with 45.1% of these patients experiencing bacterial complications. There was an absence of pneumocystis pneumonia in the study population. Despite the small sample size and limited timeline, this study suggests that antibiotic prophylaxis may not significantly mitigate the risk of infections in AIBD patients receiving rituximab, and the risk of infection with concomitant immunosuppression with rituximab requires additional investigation for definitive causal risk.
