Co-infection of SARS-CoV-2 and Bordetella bronchiseptica in a young man with idiopathic non-cystic bronchiectasis and vitamin D3 deficiency.

This is the first reported case, to our knowledge, of co-infection of Bordetella bronchiseptica and SARS-CoV-2 in a young patient with underlying idiopathic bronchiectasis and vitamin D3 deficiency that was treated successfully with a combination therapeutic regime integrating doxycycline, empiric therapies for COVID-19, vitamin D supplementation, and supportive ICU care. Large prospective studies are required to investigate further the role of co-infections in COVID-19 patients with bronchiectasis. Randomized control trials should examine the putative beneficial role of vitamin D supplementation in patients with COVID-19.

Deficiencies Under Plenty of Sun: Vitamin D Status among Adults in the Kingdom of Saudi Arabia, 2013.

BACKGROUND: Vitamin D deficiency has been correlated with several diseases and injuries including diabetes, osteoporosis, fractures, and falls. In the Kingdom of Saudi Arabia (KSA), current data on vitamin D status are lacking. AIMS: To inform Saudi public health authorities on the current status of blood levels vitamin D deficiency, we analyzed data from the Saudi Health Interview Survey. MATERIALS AND METHODS: The Saudi Health Interview Survey (SHIS) is a cross-sectional national multistage survey of individuals aged 15 years and above on sociodemographic characteristics, tobacco consumption, diet, physical activity, health care utilization, different health-related behaviors, and self-reported chronic conditions. A total of 10,735 participants completed a health questionnaire and were invited to the local health clinics for biomedical exams. RESULTS: 62.65% of female Saudis and 40.6% of male Saudis aged 15 years and above are deficient in vitamin D. Out of them, less than 1% males and less than 2% females consume vitamin D supplements. Women who have never married and obese individuals are more likely to be deficient in vitamin D, compared to men who were currently married and nonobese individuals. Those consuming vitamin D supplements are less likely to be deficient in vitamin D. CONCLUSIONS: Our study showed a high prevalence of vitamin D deficiency among Saudi men and women, and the results call for an increased awareness to ensure adequate levels of vitamin D for better health in Saudi Arabia. Moreover, our findings are certainly relevant for other countries in the Gulf region or countries with similar cultures, clothing, and religions.

Emerging novel and antimicrobial-resistant respiratory tract infections: new drug development and therapeutic options.

The emergence and spread of antimicrobial-resistant bacterial, viral, and fungal pathogens for which diminishing treatment options are available is of major global concern. New viral respiratory tract infections with epidemic potential, such as severe acute respiratory syndrome, swine-origin influenza A H1N1, and Middle East respiratory syndrome coronavirus infection, require development of new antiviral agents. The substantial rise in the global numbers of patients with respiratory tract infections caused by pan-antibiotic-resistant Gram-positive and Gram-negative bacteria, multidrug-resistant Mycobacterium tuberculosis, and multiazole-resistant fungi has focused attention on investments into development of new drugs and treatment regimens. Successful treatment outcomes for patients with respiratory tract infections across all health-care settings will necessitate rapid, precise diagnosis and more effective and pathogen-specific therapies. This Series paper describes the development and use of new antimicrobial agents and immune-based and host-directed therapies for a range of conventional and emerging viral, bacterial, and fungal causes of respiratory tract infections.

National surveillance of antimicrobial resistance among Gram-positive bacteria in Saudi Arabia.

BACKGROUND: Antimicrobial-resistant Gram-positive bacteria are important causes of serious infections. METHODS: Between January and December 2009, we examined clinical Gram-positive isolates from 24 hospitals across Saudi Arabia. RESULTS: Among the 13750 isolates, Staphylococcus aureus (62.3%) was the commonest, followed by non-group A beta-haemolytic streptococci (14.8%), group A beta-haemolytic streptococci (7.1%), coagulase-negative staphylococci (6.6%), pneumococci (6.0%), and enterococci (3.1%). Resistance rates were high among S. aureus (methicillin-resistant S. aureus: 32%), coagulase-negative staphylococci (oxacillin: 63%) and pneumococci (penicillin G: 33%; erythromycin: 26%; ceftriaxone: 11%); low among enterococci (vancomycin: 1%) and among beta-haemolytic streptococci. Resistance rates varied between regions, but comparison was complicated by differences in antibiotics tested. Many relevant antibiotics were tested against few isolates (e.g. ampicillin, vancomycin, and high-level gentamicin versus enterococci) while unhelpful tests were widely performed (e.g. cefotaxime, ceftriaxone, and imipenem versus staphylococci. CONCLUSION: Resistance is widespread in staphylococci and pneumococci, but not enterococci and beta-haemolytic streptococci in Saudi Arabia. Rationalization of antibiotic panels tested is urgently needed.

Tuberculosis comorbidity with communicable and non-communicable diseases: integrating health services and control efforts.

Recent data for the global burden of disease reflect major demographic and lifestyle changes, leading to a rise in non-communicable diseases. Most countries with high levels of tuberculosis face a large comorbidity burden from both non-communicable and communicable diseases. Traditional disease-specific approaches typically fail to recognise common features and potential synergies in integration of care, management, and control of non-communicable and communicable diseases. In resource-limited countries, the need to tackle a broader range of overlapping comorbid diseases is growing. Tuberculosis and HIV/AIDS persist as global emergencies. The lethal interaction between tuberculosis and HIV coinfection in adults, children, and pregnant women in sub-Saharan Africa exemplifies the need for well integrated approaches to disease management and control. Furthermore, links between diabetes mellitus, smoking, alcoholism, chronic lung diseases, cancer, immunosuppressive treatment, malnutrition, and tuberculosis are well recognised. Here, we focus on interactions, synergies, and challenges of integration of tuberculosis care with management strategies for non-communicable and communicable diseases without eroding the functionality of existing national programmes for tuberculosis. The need for sustained and increased funding for these initiatives is greater than ever and requires increased political and funder commitment.

Inappropriate antimicrobial use and potential solutions: a Middle Eastern perspective.

Addressing the many challenges posed by escalating antimicrobial resistance requires a strategy at institutional, community, national, regional and international levels. Partners in the development of such a strategy should include representatives from clinical and veterinary medicine, public health, microbiology, animal husbandry, the pharmaceutical and agriculture industries as well as behavioral sciences. In the Middle East, antimicrobial resistance is a crisis at the present time. It stems from a wide range of problems; however, there are few studies from this region about factors associated with proliferating resistance. In this article, we explore inappropriate antimicrobial use in this part of the world and suggest possible solutions to mitigate the problem.

Knowledge, practice, and attitude among Iranian nurses, midwives, and students regarding standard isolation precautions.

Our goal was to assess the knowledge, attitudes, and practices regarding infection control and standard precautions among a group of nursing and midwifery instructors and students in Iran. A survey questionnaire was completed by 273 nursing and midwifery instructors and students at Shiraz University Medical Sciences during the period from May to November 2002. Two hundred thirty-one (90.9%) of the participants reported that they needed additional infection control education, especially on standard isolation precautions. There was a linear positive correlation between knowledge, practice, and attitude scores for the group of nursing, auxiliary nursing, and midwifery instructors, as well as their students (P<.05). Our study shows that there is an urgent need for evaluating education on infection control practices and standard precautions in general, as well as for structured infection control programs among nursing and midwifery staff.
