Association of asthma and herpes zoster, the role of vaccination: A literature review.

Herpes Zoster (HZ) is the reactivation of a previous infection with varicella-zoster virus (VZV) which shares the same mode of transmission as HZ. It presents with painful erythematous vesicles in a dermatome which is characterized by a burning sensation before and after the rash. Any conditions with suppressed cellular immunity example diabetes mellitus, chronic obstructive pulmonary disease, asthma, cardiovascular diseases, chronic steroid uses, malignancy, etc. causes reactivation of the virus. Impaired immune responses in asthma patients either in any age group may increase their susceptibility to HZ infection owing to skewed Th1/Th2 immunity, resulting in predominant Th2 conditions and an unwarranted Th2 cell response against respiratory allergens. Similarly, many studies have delineated the association of asthma with HZ. However, the relation between steroid use in asthma and HZ is uncertain, its immunosuppressive effect might be responsible for increased susceptibility to the infection. As HZ increases the economic burden and morbidity, its prevention should use vaccines. There are two types of Food and Drug Administration (FDA)-approved vaccine available against HSV one of which is given as a single dose vaccine called Zostavax, for people 50-59 years but its efficacy falls after 3rd dose and on the subsequent 4th dose and is also contraindicated in human immunodeficiency virus/acquired immunodeficiency syndrome, pregnancy and people taking immunosuppressive drugs. Shingrix is preferred by FDA which is a two doses vaccine that is given 6 months apart for people above 50 years and to immunocompromised people. Hence, proper counseling and education about the risks of herpes should be informed to the patients with timely utilization of the vaccine.

The scenario of self-medication practices during the covid-19 pandemic; a systematic review.

Background: Self-medication association with an ongoing pandemic is evident in the studies conducted throughout the world. To summarize the findings of previous papers, we carried out a systematic review to observe the current scenario of self-medication during COVID-19. Methodology: Scopus, Embase, Web of Science, PubMed, MedRxiv preprints, SciELO Preprints, google, and google scholar were searched using keywords related to the topic. Studies reporting original data and assessing the self-medication practices during Covid-19 were included. Results: A total of 660 papers were collected and 14 cross-sectional studies among them were finalized from 12 different countries after apposite screening processes. Our study measured that during the COVID-19 pandemic, there was a 44.786% prevalence of self-medication. Analgesics, antibiotics, and nutritional supplements were commonly practiced drugs. Pharmacy and hospital outlets were the main sources of the drugs. Fever, sore throat, body ache (muscle pain), and flu or cough were among the most frequently recorded illnesses; treatment and prevention of COVID-19 were the main culprit behind self-medication. During COVID-19, the major factors associated with self-medication were fear, anxiety, and perception regarding COVID-19. Thus, in this pandemic, fear, anxiety, and rumors regarding immunity boosters, nutritional supplements, financial burden, and easy accessibility to even non-OTC drugs; all have their fair share in self-medication practices. Conclusion: As there was heterogeneity regarding COVID-19 and self-medication found among the assessed studies, educating general people about safe self-medication practices, hazards of superfluous drug usage, and provision of an affordable quality-health system should become a priority, especially in low and middle-income countries.

Association of hypernatremia with outcomes of COVID-19 patients: A protocol for systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis aimed to assess the association of hypernatremia with the outcomes of COVID-19 patients. METHODS: We performed a systematic literature search on PubMed, Google Scholar, and Science Direct until October 2021 and found a total of 131 papers. With meticulous screening finally, 17 papers met the inclusion criteria. COVID-19 patients with sodium levels greater than the reference level were the study population and the outcome of interest was the poor outcome; such as mortality, mechanical ventilation, intensive care unit (ICU) admission, and prolonged hospital stay. The pooled estimate was calculated as the odds ratio (OR). RESULTS: There were 19,032 patients with hypernatremia in the 17 studies included. An overall random effect meta-analysis showed that hypernatremia was associated with mortality (OR: 3.18 [1.61, 6.28], P < .0001, I2 = 91.99%), prolong hospitalization (OR: 1.97 [1.37, 2.83], P < .001, I2 = 0.00%) and Ventilation (OR: 5.40 [1.89, 15.42], P < .001, I2 = 77.35%), ICU admission (OR: 3.99 [0.89, 17.78], P = .07, I2 = 86.79%). Meta-regression analysis showed the association of age with the ICU outcome of hypernatremia patients. Whereas, other parameters like male, hypertension, chronic kidney disease, and diabetes mellitus did not significantly influence the odds ratio. CONCLUSION: Hypernatremia was markedly associated with poor outcomes in patients with COVID-19. Hence, a blood ionogram is warranted and special attention must be given to hypernatremia COVID-19 patients.
