ABSTRACT

Objectives: This scoping review aimed to determine whether the COVID-19 pandemic influenced any modifications to patient selection methods or prioritisation and services provided by proton therapy centres. Method(s): This review was conducted based on the PRISMA methodology and Joanna Briggs Institute scoping review guidelines.1,2 A literature search was performed in Medline, Embase, Web Of Science and Scopus as well as grey literature. Keywords including "COVID-19" and "Proton Therapy" were used. Articles published from 1 January 2020 in English were included. In total, 138 studies were identified of which 14 articles met the inclusion criteria. A scoping review design was chosen to capture the full extent of information published relating to the aim. Result(s): Six of 14 articles included statements regarding treatment of COVID-19 patients. Three publications recommended deferred or alternative treatment, two indicated to treat urgent/emergency patients and one reported continuous treatment for infectious patients. Recurring impacts on PT provision included more frequent use of alternative therapies, reduced referrals, delayed treatment starts and CT simulation, change in treatment volume and staffing limitations due to pandemic restrictions. Consequently, telehealth consults, remote work, reduction in patient visitors, screening procedures and rigorous cleaning protocols were recommended. Discussion/Conclusion: Few publications detailed patient selection or workflow methods used during the pandemic. Further research is needed to obtain more detailed information regarding current global patient selection methods in proton therapy, collecting this data could aid in future planning for proton therapy in Australia.

ABSTRACT

Introduction: Croatian National Cancer Registry of Croatian Institute for Public Health reported that in year 2020 lung cancer was the second most common cancer site diagnosed in men with 16% and the third most common in women with 10% incidence among all cancer sites. Unfortunatelly lung cancer has the highest mortality in both men and women. Haematological malignancies had 7% share in all malignancies in both male and female cances cases. In 2020 190 newly diagnosed cases of lymphatic leukemia in men and 128 cases in women were reporeted, meaning 1.5 and 1.2% of all malignancies, respectively. Chronic lymphatic leukemia (CLL) is an advanced age disease and incidence increases with age. Impaired immunity, T and B cell dysfunction in CLL, chromosomal aberations, long-term immunosuppressive therapy and genetic factors can all cause secondary malignancies. Co- occurence of solid tumors and CLL is very rare. Although patiens with CLL have an increased risk of developing second primary malignancies including lung carcinoma, the data about their clinical outcomes are lacking. Parekh et al. retrospectively analyzed patients with simultaneous CLL and lung carcinoma over a 20-year period, and they found that ~2% of patients with CLL actually developed lung carcinoma. The authors claimed that up to 38% of patients will also develop a third neoplasm more likely of the skin (melanoma and basal cell carcinoma), larynx (laryngeal carcinoma) or colon. Currently there are no specific guidelines for concurrent CLL and non-small cell lung carcinoma (NSCLC) treatment. Usually, when the tumors are diagnosed simultaneously, treatment is based to target the most aggressive malignancy, as the clinical outcomes depend on the response of the tumor with the poorest prognosis. For this reason, a multidisciplinary approach is mandatory. Case report: A patient with history of coronary heart disease, myocardial infarction and paroxysmal atrial fibrillation was diagnosed in 2019 (at the age of 71) with B chronic lymphocytic leukemia with bulky tumor (inguinal lymph nodes 8x5 cm), stage B according to Binet, intermediate risk. He was treated with 6 cycles of chemoimmunotherapy (rituximab/cyclofosfamid/fludarabine). In 10/2019 remission was confirmed, but MSCT described tumor in the posterior segment of upper right lung lobe measuring 20x17 mm and bilateral metastases up to 11 mm. Bronchoscopy and biopsy were performed, and EGFR neg, ALK neg, ROS 1 neg, PD-L1>50% adenocarcinoma was confirmed. He was referred to Clinical Hospital Center Osijek where monotherapy with pembrolizumab in a standard dose of 200 mg intravenously was started in 01/2020. Partial remission was confirmed in October 2020. Immunotherapy was discontinued due to development of pneumonitis, dysphagia and severe weight loss (20kg), but without radiologically confirmed disease progression. At that time he was referred to our hospital for further treatment. Gastroscopy has shown erosive gastritis with active duodenal ulcus, Forrest III. Supportive therapy and proton pump inhibitor were introduced. After complete regression of pneumonitis, improvement of general condition and resolution of dysphagia, no signs of lung cancer progression were found and pembrolizumab was reintroduced in 12/2021. Hypothyroidism was diagnosed in 01/2021 and levothyroxine replacement ther apy was started. In 03/2021 he underwent surgical removal of basal cell carcinoma of skin on the right temporal region with lobe reconstruction. From 02/2021, when pembrolizumab was reintroduced, regression in tumor size was continously confirmed with complete recovery of general condition. He was hospitalized for COVID 19 infection in 09/2021, and due to complications pembrolizumab was discontinued till 11/2021. Lung cancer immunotherapy proceeded till 11/2022, when Multidisciplinary team decided to finish pembrolizumab because of CLL relapse. CLL was in remission till August 2022 when due to B symptoms, lymphcytosis, anemia and generalized lymphadenopathy, hematological workup including biopsy of cervical lymph node was performed and CLL/SLL relapse was confirmed. Initially chlorambucil was introduced, but disease was refractory. Based on cytogenetic test results (IGHV unmutated, negative TP53) and due to cardiovascular comorbidity (contraindication for BTK inhibitors) venetoclax and rituximab were started in 01/2023. After just 1 cycle of treatment normal blood count as well as regression of B symptoms and peripheral lymphadenopathy occured, indicating the probability of complete disease remission. In our patient with metastatic lung adenocarcinoma excellent disease control is achieved during 41 month of treatment in first line setting. Furthermore, relapsed/refractory CLL/SLL is currently in confirmed remission. Conclusion(s): Successful treatment of patients with multiple primary malignancies is based on multidisciplinarity, early recognition and management of side effects, treatment of comorbidities with the aim of prolonging life, controlling symptoms of disease and preserving quality of life.

ABSTRACT

Radiotherapy-induced secondary malignancy is a well-known occurrence. During the COVID-19 pandemic, many people have undergone serial computed tomography (CT) imaging, and concerns have been raised regarding radiation-induced malignancies due to frequent scanning. Accordingly, various low and ultra-low-dose CT (LDCT) thorax protocols have been developed to reduce the dose of radiation. Major governing bodies worldwide have established guidelines regarding the indications for CT scans and chest X-rays during the pandemic. We, therefore, aimed to provide facts about the effects of radiation (both diagnostic and therapeutic). Through this article, we intend to break the myths and 'mithya' (misbeliefs) regarding diagnostic radiation and its association with cancer in this COVID-19 era. For this review, we performed a search in Google using specific keywords pertaining to imaging during COVID-19 and radiation risk. We also included the names of various global governing bodies in the Google search. We included only full text articles and guidelines from authentic websites. From this review, we conclude that if we follow the recommendations of various global governing bodies and use CT scan only in cases of moderate to severe COVID-related symptoms, adhere to the principle of 'as low as reasonably achievable' for radiation protection, and use LDCT scan protocols, we can significantly reduce the mean effective radiation dose delivered and the estimated cancer risk.Copyright © 2023 Cancer Research, Statistics, and Treatment.

ABSTRACT

Background: There exists a treatment dilemma regarding the optimal and effective use of therapeutic drugs (hydroxychloroquine/chloroquine/azithromycin) for COVID-19. Furthermore, with changing guidelines, the data on drug utilization patterns across India are limited. Hence, this study was conducted to assess the prescription pattern and drug utilization trends in COVID-19 patients with the aim to study the drug utilization pattern in patients affected with COVID-19 in a dedicated COVID-19 hospital. Aims and Objectives: The objectives of the study are as follows: (1) To study drug utilization patterns according to the severity of the disease. (2) To study the prevalence of adverse drug reactions (ADRs). Materials and Methods: Data were collected retrospectively from 100 medical records of patients 18 years irrespective of sex admitted in the COVID ward and ICU of a dedicated COVID hospital from May to August 2020. Pregnant and lactating women were excluded from the study. ADRs reported were also analyzed. Results: About 71% were mild in this study, 18% were moderate, and 11% were severe COVID-19 patients. Overall, the most common drugs prescribed were multivitamins, followed by pantoprazole, paracetamol, and azithromycin. Hydroxychloroquine was prescribed in 22%, favipiravir in 7%, and remdesivir in 3% of cases. The majority of moderate COVID patients received injectables piperacillin-tazobactam, methylprednisolone, and enoxaparin. The mean number of medications, duration of admission, and number of days on oxygen were higher and significant in moderate compared to mild and severe COVID patients. Overall, ADRs were encountered in 9% of cases. Conclusion: The prescribed pattern of drugs was by the national standard guidelines. Multivitamins, followed by pantoprazole, paracetamol, and azithromycin dominated the prescription pattern. Polypharmacy was encountered, which needs to be addressed for the rational use of drugs.

ABSTRACT

Proton Pump Inhibitors are used widely to manage many gastric acid-related conditions such as gastroesophageal disease, gastritis, esophagitis, Barrett's esophagus, Zollinger-Ellison syndrome, peptic ulcer disease, nonsteroidal anti-inflammatory drug-associated ulcers, and Helicobacter pylori eradication, around the globe. This review article focuses on adverse effects associated with the long-term use of proton pump inhibitors. Various observational studies, clinical trials, and meta-analyses have established the adverse effects associated with the long-term use of proton pump inhibitors including renal disorders (acute interstitial nephritis, acute kidney injury, chronic kidney disease, and end-stage renal disease), cardiovascular risks (major adverse cardiovascular events, myocardial infarction, stent thrombosis, and stroke), fractures, infections (Clostridium difficile infection, community-acquired pneumonia, and Coronavirus disease 2019), micronutrient deficiencies (hypomagnesemia, anemia, vitamin B12 deficiency, hypocalcemia, hypokalemia), hypergastrinemia, cancers (gastric cancer, pancreatic cancer, colorectal cancer, hepatic cancer), hepatic encephalopathy, and dementia. Clinicians including prescribers and pharmacists should be aware of the adverse effects of taking proton pump inhibitors for an extended period of time. In addition, the patients taking proton pump inhibitors for long-term should be monitored for the listed adverse effects. The American Gastroenterological association recommends a few non-pharmacological measures and the use of histamine 2 blockers to lessen gastrointestinal symptoms of gastroesophageal reflex disease and the utilization of proton pump inhibitors treatment if there is a definitive indication. Additionally, the American Gastroenterological association's Best Practice Advice statements emphasize deprescribing when there is no clear indication for proton pump inhibitors therapy.

ABSTRACT

Theoretical and experimental studies are performed on the new organic-inorganic hybrid molecule N-(2,6-dimethylphenyl)-1-piperazineacetamide. The vibrational spectra of the molecule are characterized using FT-IR and FT-Raman in the range 4000-600 cm(-1) and 4000-100 cm(-1), respectively. Density functional theory with B3LYP/3-21G and B3LYP/cc-pVDZ basis sets is used to calculate energy, geometrical structure, and vibrational modes of stretching, bending, and torsion. The VEDA software Autodock Vina revealed a good binding is employed to calculate the detailed vibrational assignments. The theoretical and experimental vibrational data are compared to support the present study. Density functional theory is used to calculate thermodynamic parameters (heat capacity, entropy, and enthalpy) and nonlinear optical properties. The software Gaussian09W and Gaussview 6.0 are used for theoretical calculations. Molecular docking studies are carried out to investigate the effect of the titled molecule against various proteins such as SARS-CoV-2 that affect the immune system in humans. Chemical shifts are identified using carbon and proton NMR. Non-covalent interactions are studied using a reduced density gradient. The chemical reactivity and selectivity for a local reactivity site are analyzed with the help of Fukui functions.

ABSTRACT

Increased usage of chemical disinfectants during the COVID-19 pandemic may impact the chemical composition of indoor air in residential and commercial buildings. This study characterized gas-phase concentrations of volatile organic compounds (VOCs) during multi-surface disinfection activities in a tiny house research facility. This unique facility provided a controlled, yet realistic environment for simulating whole-building disinfection events. VOCs were measured in real-time (1 Hz) in the bulk air of the tiny house with a proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS). In addition, particle number (PN) size distributions were measured with a high-resolution electrical low-pressure impactor (HR-ELPI+). PTR-TOF-MS measurements demonstrate that chemical disinfectant spray products applied to multiple surfaces can substantially increase indoor VOC concentrations. © 2022 17th International Conference on Indoor Air Quality and Climate, INDOOR AIR 2022.

ABSTRACT

Hepatitis A is a common viral infection worldwide that is transmitted via the fecal-oral route. Since the introduction of an efficient vaccine, the incidence of infection has decreased but the number of cases has risen due to widespread community outbreaks among unimmunized individuals. Classic symptoms include fever, malaise, dark urine, and jaundice, and are more common in older children and adults. People are often most infectious 14 days prior to and 7 days following the onset of jaundice. We will discuss the case of a young male patient, diagnosed with acute hepatitis A, leading to fulminant hepatitis refractory to conventional therapy and the development of subsequent kidney injury. The medical treatment through the course of hospitalization was challenging and included the use of L-ornithine-L-aspartate and prolonged intermittent hemodialysis, leading to a remarkable outcome. Hepatitis A is usually self-limited and vaccine-preventable;supportive care is often sufficient for treatment, and chronic infection or chronic liver disease rarely develops. However, fulminant hepatitis, although rare, can be very challenging to manage as in the case of our patient.Copyright © 2023 The Author(s).

ABSTRACT

Background: Mitochondrial (mt) dysfunction has been described in acute severe SARS-CoV2 infection. It remains unclear whether the disturbances in mt are also present in post-acute sequelae of COVID-19 (PASC). Method(s): We analyzed cross-sectional data from participants without history of COVID and SARS-CoV2 antibody negative (COVID-), with documented prior COVID and full recovery (COVID+ PASC-), and with prior COVID with PASC as defined by the CDC (COVID+PASC+). Mt respiration was measured from peripheral blood mononuclear cells utilizing the Seahorse XFe96 analyzer. Generalized linear regression was used to compare estimates of mt and non-mt respirations, and unadjusted odds ratios using multinomial logistic regression to assess if mt respiration were associated with PASC. Result(s): For this analysis, 59 participants were enrolled, 71.19% (n=42) had a confirmed COVID-19 diagnosis. The overall mean age was 47.47 +/- 14.86 years, 69.49% (n=41) were females and 33.90% (n=20) were non-white race. There was no difference in demographics between participants with and without COVID (p>=0.72). Amongst all COVID+ participants, 19% (n=11) had hypertension and 8% (n=5) had diabetes. Among all COVID+, the median time between COVID diagnosis and study evaluation was 210 (IQR: 119, 453) days, and 50% (n=21) of COVID+ experienced persistent symptoms consistent with PASC. PASC participants had the highest observed values in non-mt respiration (21.57 +/- 10.77 pmol/min), basal respiration (38.95 +/- 17.58 pmol/min), proton leak (10.41 +/- 3.1), maximal respiration (103.91 +/- 58.63 pmol/min), spare respiratory capacity (64.96 +/- 41.82 pmol/min), and ATP production (28.55 +/-14.85 pmol/min). Basal respiration, ATP production, maximal respiration, and non-mt respiration were highest in PASC compared to COVID- (p<=0.02). There was marginal evidence (p=0.05) of a mean difference (8.09 pmol/min) in ATP production between COVID+PASC+ and COVID+PASC-, without differences in proton leak (p=0.23) or spare respiration capacity (p=0.07). Every unit increase in non-mt respiration, basal respiration, maximal respiration, and ATP production increased the predicted odds of PASC by 10.99, 5.6, 1.6 and 6.2%, respectively (Figure). Conclusion(s): Individuals with PASC are consuming more oxygen and producing more ATP in the PBMCs compared to controls. There also appears to be increased PBMC ATP production between PASC and COVID+. We hypothesize that this may reflect a crucial pathogenic mechanism in PASC that may be associated with ongoing inflammation. (Figure Presented).

ABSTRACT

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus-19 disease (COVID-19) pandemic. The H-2 blocker famotidine has been suggested as an FDA-approved drug that could potentially be repurposed for treatment of COVID-19. Famotidine has since been shown to improve patient outcomes and reduce symptom severity in patients acutely ill with COVID-19. Other studies have suggested that proton pump inhibitors (PPIs) might have an association with COVID-19. OBJECTIVE: The purpose of the present study was to determine whether famotidine or any other antireflux medications have a prophylactic or detrimental effect for SARS-CoV-2 infection when taken regularly for the management of acid reflux. METHODS: An anonymous, web-based survey was distributed via email to adult otolaryngology patients to collect demographic data, past medical history, medication history, incidence of symptoms associated with COVID-19, potential exposure to SARS-CoV-2, and results of any PCR or serological testing. Associations between reflux medications and incidence of COVID-19 cases were analyzed. Statistical analysis was performed using SPSS. Chi-square with Fisher's exact test, Point-Biserial correlation, Kendall's-tau-b, independent samples t test, and the Mann-Whitney U test were used as appropriate. A binary logistic regression model was fit to determine probability of COVID-19 cases after adjustment for other risk factors. RESULTS: There were 307 patients who responded to the survey. The average age of respondents was 52.63 ± 17.03. Famotidine use was not associated with incidence of laboratory-confirmed (P= 0.717) or symptomatically suspected (P= 0.876) COVID-19. No other reflux medications were found to be significant predictors for laboratory-confirmed or suspected COVID-19 (P> 0.05). Younger age (odds ratio [OR] = 1.043, 95% CI: 1.020-1.065, P< 0.001), high risk obesity (OR = 4.005, 95% CI: 1.449-11.069, P= 0.007), and use of a corticosteroid nasal spray (OR = 3.529, 95% CI: 1.352-9.211, P= 0.010) were significant predictors for symptomatically suspected COVID-19 cases. CONCLUSIONS: There was no association between incidence of COVID-19 and use of reflux medications, including famotidine at doses used orally to manage reflux and high dose PPIs. Reflux medications did not protect against or increase the risk of COVID-19.

ABSTRACT

Since their approval by the Food and Drug Administration (FDA) in 1989, proton pump inhibitors (PPIs) have become one of the most highly utilized drugs in the United States, assuming a position as one of the top 10 most prescribed medications in the country. The purpose of PPIs is to limit the amount of gastric acid secreted by the parietal cells via irreversible inhibition of the H+/K+-ATPase pump, therefore maintaining an elevated gastric acid pH of greater than 4 for 15-21 h. Even though PPIs have many clinical uses, they are not without their adverse effects, mimicking achlorhydria. Besides electrolyte abnormalities and vitamin deficiencies, long-term use of PPIs has been linked to acute interstitial nephritis, bone fractures, poor COVID-19 infection outcomes, pneumonia, and possibly an increase in all-cause mortality. The causality between PPI use and increased mortality and disease risk can be questioned since most studies are observational. Confounding variables can greatly affect an observational study and explain the wide-ranging associations with the use of PPIs. Patients on PPIs are generally older, obese, sicker with a higher number of baseline morbidities, and on more medications than the compared PPI non-users. These findings suggest that PPI users are at a higher risk of mortality and complications based on pre-existing conditions. This narrative review aims to update readers on the concerning effects that proton pump inhibitor use can have on patients and give providers a resource to create informed decisions on appropriate PPI use.

ABSTRACT

Background and aim: The long-term consequences of COVID- 19 infection on the gastrointestinal tract remain unclear. Here we aimed to evaluate the prevalence of gastrointestinal symptoms and post-COVID-19 disorders of gut-brain interaction (DGBI) after hospitalization for SARS-CoV-2 infection. Material(s) and Method(s): GI-COVID19 is a prospective, multicenter, controlled study. Patients with and without COVID-19 diagnosis were evaluated upon hospital admission and after 1, 6, and 12 months post-hospitalization. Gastrointestinal symptoms, anxiety, and depression were assessed using validated questionnaires, namely the Gastrointestinal Symptoms Rating Scale (GSRS), the Hanxiety and Depression Scale (HADS) and the Rome IV Diagnostic Questionnaire for Functional Gastrointestinal Disorders in Adults. Result(s): The study included 2183 hospitalized patients. The primary analysis included a total of 883 patients (614 COVID-19 patients and 269 controls) due to the exclusion of patients with pre-existing gastrointestinal symptoms and/or surgery. At enrollment, gastrointestinal symptoms were more frequent among COVID-19 patients than in the control group (59.3% vs. 39.7%, P<0.001). At the 12-month follow- up, constipation and hard stools were significantly more prevalent in controls than in COVID-19 patients (16% vs. 9.6%, P=0.019 and 17.7% vs. 10.9%, P=0.011, respectively). Compared to controls, COVID- 19 patients reported higher rates of irritable bowel syndrome (IBS) according to Rome IV criteria: 0.5% vs. 3.2%, P=0.045. Factors significantly associated with IBS diagnosis included history of allergies, chronic intake of proton pump inhibitors, and presence of dyspnea. [Table presented] At the 6-month follow-up, the rate of COVID-19 patients fulfilling the criteria for depression was higher than among controls. Conclusion(s): Compared to controls, hospitalized COVID-19 patients had fewer complaints of constipation and hard stools at 12 months after acute infection. COVID-19 patients had significantly higher rates of IBS than controls. ClinicalTrials.gov number, NCT04691895.Copyright © 2023. Editrice Gastroenterologica Italiana S.r.l.

ABSTRACT

The study of tautomerism in biologically relevant heterocycles is essential, as it directly affects their chemical properties and biological function. Lactam-lactim tautomerization in pyridine/pyrazine derivatives is such a phenomenon. Favipiravir, a pyrazine derivative, is an essential antiviral drug molecule having notable performance against SARS-CoV-2. Along with a better yielding synthetic method for favipiravir, we have also investigated the lactam-lactim tautomerization of favipiravir and its analogous molecules. Most of these molecules were crystalized and studied for various interactions in their lattice. Many interesting supramolecular interactions such as hydrogen bonding, pi-pi stacking and halogen bonding were revealed during the analysis. Some of these structures show interesting F-F halogen bonding and water channels in their solid state.Copyright © 2022 The Royal Society of Chemistry.

ABSTRACT

Background: The importance of vaccination in today's world is extremely important given the COVID-19 epidemic. About 30% of the world's population suffers from allergies. Among them, 25% of patients according to the WHO, had an episode of urticaria at least once in their life. Urticaria is one of the most common allergic diseases, which is the highest in-patient admission toll at Dnipro Allergy Center. During the year 2021, 600 patients with urticaria were treated in the hospital. Patients with chronic recurrent urticaria do not want to be vaccinated because of the fear of complications such as anaphylaxis.Vaccination of urticaria patients without complications. Method(s): The study involved 45 patients aged 18 to 65 years, with a mean age of 34.3 +/- 1.0 (13 males and 32 females). The average experience of the disease is 3.6 +/- 0.8 years. Patients with chronic recurrent urticaria were admitted to the in-patient unit. Prior to vaccination, they were tested for tryptase levels, a detailed platelet blood test, coagulogram, D-dimer, and ECG. Result(s): Many patients had concominant gastrointestinal pathology in the form of gastro-esophageal reflux disease (GERD) -20 patients (44.4%), peptic ulcer disease disease -17 patients (37.7%), or stomach pathology in 45 patients (100%), which required proton pump inhibitors (PPI). Given that PPIs are a risk factor for anaphylaxis, according to EAACI documents, PPIs were discontinued three days before vaccination. Serum tryptase levels were elevated in 3 patients (13 mug/l, 16 mug/l, 32 mug/l). All patients underwent premedication. At normal serum tryptase levels, patients received 1-fold dose of desloratadine, and at high serum tryptase levels: 13 mug/l, 16 mug/l and 32 mug/l, patients received 4-fold dose of desloratadine. After 30 minutes vaccination shot was carried out without side effects and without complications of allergic nature. The second vaccination shot was also protected by antihistamines, so all the patients we observed had received 2 shots of the vaccine not complicated by side effects such as fever or allergic reactions. Conclusion(s): All patients were vaccinated without complications. In urticaria patients, serum tryptase levels should be determined prior to vaccination. Depending on the level of tryptase, appropriate premedication is prescribed: with a high level of tryptase -4- fold dose of desloratodine, with a normal level -1- fold dose. All patients with urticaria should be diagnosed with concomitant pathology in order to correct the basic therapy before vaccination.

ABSTRACT

PURPOSE: Proton pump inhibitors (PPIs) are widely prescribed medications. Various adverse clinical effects of PPIs have been reported in the literature, particularly over the past decade. The purpose of this article is to review published data primarily describing adverse effects associated with PPI use and to help clinicians determine which patients may still benefit from therapy despite safety concerns. SUMMARY: Associations between PPIs and the following have been described: bone fracture, acute and chronic kidney disease, gastrointestinal infections, deficiencies in vitamin B12 and magnesium, and coronavirus disease 2019 and respiratory infections. For inclusion in this review, studies must have evaluated potential adverse events associated with PPIs as a primary or secondary objective. Increased risks of bone fracture, acute and chronic kidney disease, gastrointestinal infections, and magnesium deficiency were consistently reported, albeit mostly in studies involving low-quality data (case-control and/or observational studies) and subject to bias. In the only pertinent randomized controlled trial to date, chronic pantoprazole use was associated with a greater risk of enteric infections relative to placebo use; there was no significant between-group difference in any other adverse event evaluated. PPIs continue to be recommended by the American College of Gastroenterology as a first-line treatment for management of gastroesophageal reflux disease and in the acute period following upper gastrointestinal and ulcer bleeding. CONCLUSION: Higher-quality data is needed to better understand PPI-associated risks of the adverse effects listed above. Until then, clinicians may consider greater vigilance with PPI use; however, the data does not demonstrate a need for wide adoption of de-escalation strategies solely out of safety concerns.

ABSTRACT

Aim: In our study, the effects of methylprednisolone and anakinra drugs in the treatment of hyperinflammation in severe COVID-19 patients were investigated. Material(s) and Method(s): In this single-center retrospective study, severe COVID-19 patients followed up with signs of hyperinflammation were examined. The patients were examined in the Sequential Treatment Group receiving high-dose methylprednisolone followed by Anakinra, and the concomitant treatment group receiving both at the same time. Inflammatory parameters, imaging findings, and way of leaving the intensive care unit of the patients were compared. Result(s): A total of 87 patients were included in the present study. In both treatment groups, an increase in lymphocyte levels and a decrease in CRP, lactate dehydrogenase (LDH) and ferritin levels were detected at the end of treatment values compared to the initial treatment values. (p<0.001 and p<0.001). Also, LDH values after the treatment were significantly lower in the concomitant treatment group than in the sequential treatment group (p=0.049). In the present study, 53 of the patients were discharged with good recovery and 34 died. The mortality rate was 31% in the concomitant treatment group and 43% in the sequential treatment group. In terms of mortality, numerical findings in favor of the concurrent treatment group were determined. Discussion(s): In addition to the studies in the literature, it was found that the concomitant use of Methylprednisolone and Anakinra can be an effective treatment option that reduces mortality and improves inflammatory parameters.Copyright © 2022, Derman Medical Publishing.

ABSTRACT

Over the last few years, we have seen 11 patients presenting with proton pump inhibitor (PPI) photosensitivity at our tertiary referral photodiagnostic service and in our local dermatology department. Many adverse effects, including the discovery in 2020 of an almost twofold increased risk of severe COVID-19, of this widely used group of drugs have been noted (Lee SW, Ha EK, Yeniova AO et al. Severe clinical outcomes of COVID-19 associated with proton pump inhibitors: a nationwide cohort study with propensity score matching. Gut 2020;DOI: 10.1136/gutjnl-2020-322248). Although PPIinduced phototoxicity has been described, phototest results have not been reported and all clinical presentations have not been described. We aimed to identify all patients with PPI photosensitivity who presented to our unit. We sought to better understand their clinical characteristics, blood test results and photodiagnostic results. We retrospectively reviewed all case notes and investigation results of patients who were diagnosed with PPI photosensitivity. Eleven patients were identified to have been seen between 2014 and 2019. Two patients were male and nine were female. Mean duration of disease was 3 6 years and mean duration of PPI ingestion was 5 years. Five patients presented with a drug-induced lupus pattern [subcutaneous lupus erythematosus (SCLE;n = 2), papulosquamous SCLE and discoid (n = 1), tumid (n = 1) and acute cutaneous (n = 1)], four with drug-induced phototoxicity (sunburn-like) and two with a drug-induced solar urticaria relating to a lupus mechanism. The majority of patients reported symptoms on sun-exposed sites. The most common indication for PPI prescription was gastroesophageal reflux disease with omeprazole being the most commonly prescribed PPI. All patients underwent phototesting. Three patients were not on an PPI while undergoing phototesting and did not demonstrate photosensitivity. Of the remaining patients who underwent phototesting the most common finding was delayed sensitivity to ultraviolet A and to visible light. Druginduced photosensitivity can be a challenging diagnostic entity owing to the varied clinical presentation and heterogeneous time to onset. We present this case series to further help clinicians in recognizing the clinical and diagnostic pattern of photosensitivity present with PPI use.
