Background

Understanding post-infection immunity with the first SARS-CoV-2 variant may provide valuable insights into the duration and effectiveness of the humoral immune response. This study aims to characterize the serological profile of naïve individuals infected with the first SARS-CoV-2 variant.

Methods

A prospective study with repeated measures was conducted in Tunisia, from March to October 2020, during the first wave of COVID-19. Adults confirmed with confirmed COVID-19 were monitored during the first wave of the pandemic. ELISA blood tests were conducted at multiple intervals: day 7, day 14, and at 1, 2, 3, 4, and 6 months post-infection.

Results

173 serum samples were collected from immunologically naïve individuals infected with the first circulating SARS-CoV-2 variant, ranging from 7 days to 6 months post-RT-PCR confirmation. The study revealed a robust humoral immune response in most participants, with 94.1% testing positive for IgM anti-N, 88.2% for IgM anti-S, 98% for IgG anti-N, and 100% for IgG anti-S antibodies. Anti-N IgM antibodies peaked at days 14 and 30 with high positive values (>0.260), while anti-S IgM antibodies showed elevated levels (>0.990) at days 7 and 14. For IgG, anti-N antibodies reached their highest levels (>0.810) at month 4, while anti-S IgG antibodies maintained high positive values (>0.490) at days 7 and 14, and remained elevated at months 4 and 6. No significant differences in antibody levels were observed based on gender, age, comorbidities, or symptoms presence.

Conclusion

A typical adaptive immune response was observed in naïve individuals infected with the initial SARS-CoV-2 variant, showing typical IgM and IgG antibody production from day 7 to month 6. We specifically investigated immunologically naïve individuals infected with the first circulating SARS-CoV-2 variant, from the earliest stage of infection, a context that is no longer reproducible.

Community pharmacists’ history taking practice in responding to acute uncomplicated cystitis: A simulated patient study from Sudan

by Riham M. Hamadouk, Esra D. Albashair, Einass M. Alshareif, Ali Awadallah Saeed, Bashir A. Yousef

Background

Today, community pharmacists’ responsibilities have expanded beyond the traditional role to include the management of minor ailments. Acute uncomplicated cystitis is one of the most prevalent medical conditions seen in primary healthcare and can be managed by community pharmacists (CPs).

Objectives

To evaluate community pharmacists’ history-taking practice when responding to patients with acute uncomplicated cystitis.

Methods

A cross-sectional simulated patient study was conducted from November 2022 to January 2023 in Khartoum locality targeting only pharmacists. Six trained female students played the simulation in which they pretended to have the clinical symptoms of acute uncomplicated cystitis and requested treatment for their condition. The Interactions during the simulation were documented immediately in a data collection form after each visit. Descriptive statistics were used to report the study outcomes.

Results

A total of 238 community pharmacies were visited. The majority of the pharmacists were female. The mean of the number of questions that were asked by the pharmacists was 1 (SD = 1.6) questions. Among the studied pharmacists, 45.4% asked at least one question during patient assessment. The most asked question was if the patient has a fever, representing 61 (25.6%) CPs, followed by if there is vaginal discharge, representing 38 (16%) CPs. In response to scenario 47 (19.7%) CPs decided to refer the patient to a physician, and 45 (18.9%) of the CPs advised the patient to increase water intake.

Conclusions

The study has revealed a poor history-taking practice towards acute uncomplicated cystitis during patient assessment. Further studies exploring pharmacists’ involvement in patient assessment are required. Strategies to improve community pharmacists’ practice, like continuing pharmacy education and providing a national guideline regarding patient assessment should be considered seriously.

Por: Sultana Samapti · M. M. · Hossain · K. M. · Riha · F. A. · Showkat · N. B. · Begum · T. · Rahman · M. A. · Rasul · M. G. — Enero 7th 2026 at 04:50
Background

Antimicrobial resistance (AMR) is a critical public health issue in Bangladesh, exacerbated by the widespread practice of non-prescribed antibiotic dispensing. This study seeks to assess their knowledge and attitudes, particularly how these factors influence non-prescribed antibiotic dispensing practices in Bangladesh.

Methods

A total of 287 pharmacy staff across four regions of Bangladesh were included in the study. Data were collected using a structured questionnaire assessing knowledge, attitudes and practices regarding non-prescribed antibiotic dispensing.

Results

The study found that 92.4% of respondents dispensed antibiotics without prescriptions. The practice was significantly more prevalent among those with poor knowledge (99.28% in below-average vs 86.09% in above-average knowledge groups, p

Conclusion

These findings highlight knowledge and attitude towards antibiotic dispensing play a vital role where weak regulation, education and economic incentives further worsen the situation. Urgent interventions, including improved pharmacist training, prescription monitoring and public awareness campaigns, are essential to reduce non-prescribed antibiotic dispensing and align practices with Bangladesh’s National Action Plan on AMR.

Objective

Vitamin D deficiency during pregnancy is a global health concern, contributing to adverse maternal and fetal outcomes. Despite its importance, limited data exist on vitamin D status and its determinants among pregnant women in Ethiopia. This study aimed to assess the prevalence and determinants of vitamin D deficiency among pregnant women in their first and second trimesters in Gondar Town, Ethiopia, 2024.

Design and setting

A facility-based cross-sectional study was conducted at the antenatal care unit of University of Gondar Comprehensive Specialized Hospital from January to March 2024.

Methods

Eligible participants were selected using a simple random sampling technique. Sociodemographic, behavioural and clinical data were collected through structured questionnaires and medical record reviews. Serum levels of vitamin D, calcium and alkaline phosphatase were analysed using the Beckman Coulter clinical chemistry analyser. Statistical comparisons between pregnant women in the first and second trimesters were performed using the independent t-test. Determinants of vitamin D deficiency were identified using multivariate logistic regression analysis.

Participants

384 pregnant women in their first or second trimester.

Results

The prevalence of vitamin D deficiency (90 mm Hg) (AOR 0.28, 95% CI 0.11 to 0.70), lower dietary diversity (AOR 3.17, 95% CI 1.13 to 8.89), lower fish and fish oil consumption habit (AOR 3.01, 95% CI 1.03 to 8.77; AOR 12.27, 95% CI 1.50 to 100.42) were the key predictors associated with serum vitamin D defiency.

Conclusion and recommendation

Nearly half of the pregnant women in Gondar Town exhibit vitamin D deficiency, showing a challenging public health concern. Thus, targeted interventions, such as dietary supplementation and lifestyle modifications, are urgently needed to address the problem and improve maternal and neonatal health outcomes.

Introduction

Atopic dermatitis (AD) is a chronic inflammatory skin condition that impairs the quality of life of affected paediatric patients and their families. Dupilumab, an antagonist of the shared alpha chain subunit of the cytokines interleukin-4 and interleukin-13, has revolutionised the management of moderate-to-severe AD by effectively targeting type 2 inflammation. However, live attenuated vaccines, including live attenuated influenza vaccines (LAIVs), are contraindicated during dupilumab therapy owing to limited safety data. This restriction poses challenges to immunisation strategies, particularly in paediatric populations. This study aims to evaluate the safety and efficacy of LAIV in paediatric patients with AD undergoing dupilumab therapy.

Method and analysis

This multicentre, prospective, single-arm, open-label trial will enrol 50 paediatric patients aged 2–18 years with AD undergoing dupilumab treatment. The participants will receive intranasal LAIV, followed by a 25-week observation period after vaccination. The primary outcome is the proportion of participants with a four-fold or greater increase in haemagglutination inhibition titres against influenza strains A(H1N1), A(H3N2) and B at 4 weeks post vaccination. The secondary outcomes include the incidence of influenza and systemic or local adverse events, such as injection site reactions, fever and other influenza-like symptoms observed within 4 weeks of vaccination. Exploratory endpoints include the evaluation of immunosuppressive markers such as neutrophil counts, lymphocyte subsets and serum immunoglobulin G levels. Safety analyses will assess the frequency of each adverse event, whereas efficacy analyses will focus on immunogenicity and influenza incidence during the 25-week follow-up period. This study aims to provide critical safety and immunogenicity data to guide immunisation strategies in biologically treated paediatric patients with AD.

Ethics and dissemination

This study complies with the principles of the Declaration of Helsinki and received ethics approval from the Institutional Review Board of Chiba University Hospital as a specified clinical trial. Informed consent and assent will be obtained as appropriate based on the participants’ ages. These findings will be disseminated through peer-reviewed journals and scientific conferences to inform clinical vaccination strategies for biologically treated populations.
