Pneumonia in the web

• https://en.wikipedia.org/wiki/Pneumonia
  "Pneumonia affects approximately 450 million people globally (7% of the population) and results in about 4 million deaths per year"
  "Pneumonia often shortens suffering among those already close to death and has thus been called "the old man's friend"."
  "Pneumonia is due to infections caused primarily by bacteria or viruses and less commonly by fungi and parasites."
  "Conditions and risk factors that predispose to pneumonia include
  • smoking, immunodeficiency, alcoholism, chronic obstructive pulmonary disease, asthma, chronic kidney disease, and liver disease."
  • Note by VitaminDWiki - every one of those risk factors is also associated with low vitamin D levels
• https://en.wikipedia.org/wiki/Community-acquired_pneumonia much less likely to be due to a superbug
• Sunshine, rainfall, humidity and child pneumonia in the tropics: time-series analyses June 2013
  "Lack of sunshine was most strongly associated with pneumonia in both lagged regression. . . and case-crossover analysis"
  "This association is well known in temperate settings but has not been noted previously in the tropics"

Pneumonia elderly death 12X more likely when vitamin D less than 12 ng – 2011

Vitamin D, Innate Immunity and Outcomes in Community Acquired Pneumonia
1. Leong Leow1, 2. Talia Simpson3, 3. Ray Cursons3, 4. Noel Karalus1, 5. Robert J Hancox1,2,*
DOI: 10.1111/j.1440-1843.2011.01924.x

Background and objective Vitamin D regulates the production of the antimicrobial peptides cathelicidin and beta defensin-2, which play an important role in the innate immune response to infection. We hypothesised that vitamin D deficiency would be associated with lower levels of these peptides and worse outcomes in patients admitted to hospital with community-acquired pneumonia.

Methods Associations between mortality and serum levels of 25-hydroxyvitamin D, cathelicidin, and beta defensin-2 were investigated in a prospective cohort of 112 patients admitted with community-acquired pneumonia during winter.

Results Severe 25-hydroxyvitamin D deficiency (<30nmol/L) was common in this population (15%) and was associated with a higher 30-day mortality compared to patients with sufficient 25-hydroxyvitamin D(>50nmol/L) (OR 12.7, 95%CI 2.2-73.3, p = 0.004).

These associations were not explained by differences in age, co-morbidities, or the severity of the acute illness.
Neither cathelicidin nor beta defensin-2 levels predicted mortality, although there was a trend towards increased mortality with lower cathelicidin (p = 0.09).
Neither cathelicidin nor beta defensin-2 levels correlated with 25-hydroxyvitamin D.

Conclusions 25-hydroxyvitamin D deficiency is associated with increased mortality in patients admitted to hospital with community-acquired pneumonia during winter.
Contrary to our hypothesis, 25-hydroxyvitamin D levels were not associated with levels of cathelicidin or beta defensin-2.

High-dose Vitamin D reduces recurrent pneumonia by half - meta-analysis Oct 2020

Efficacy of High-Dose Vitamin D Supplementation as an Adjuvant Treatment on Pneumonia: Systematic Review and a Meta-Analysis of Randomized Controlled Studies

The purpose of this meta-analysis was to summarize randomized controlled trial (RCT) evidence and evaluate the efficacy and safety of vitamin D (VD) supplementation as an adjunct to antibiotics for the treatment of pneumonia. Data sources published from the inception dates up to January 2020 were searched. RCTs of VD supplementation of any duration, age, and dosing regimen type were eligible for inclusion if data on pneumonia were collected. Thirteen studies (4786 randomized participants) fulfilled eligibility criteria.
VD supplementation significantly increased levels of serum 25(OH)D (mean difference = 15.97; 95% CI, 7.49–24.44; P = .002) and reduced incidence of repeat episodes of pneumonia (risk ratio [RR] = 0.68; 95% CI, 0.50–0.93; P = .02).
Subgroup analysis revealed VD supplementation had more reducing effects on repeat episodes of pneumonia among participants in trials in which the population were children (RR = 0.66; 95% CI, 0.48–0.90), duration <3 months (RR = 0.55; 95% CI, 0.33–0.91), or
dose of VD <300,000 IU (RR = 0.51; 95% CI, 0.29–0.89).
Although our results suggested that VD supplementation had a positive effect on recovery rate of pneumonia (RR = 1.28; 95% CI, 0.94–1.74; I2 = 13%), there was no statistical difference (P = .12).
High-dose VD intervention may have an effect on reducing the incidence rate of repeat episodes of pneumonia by enhancing immune efficacy, although more population studies are needed to support that VD supplementation has therapeutic effects on pneumonia itself.
