Table 3 Human studies on NSW and inflammation

From: Night shift work and breast cancer: from etiopathology to precision risk analysis

NSW Effect

Parameter(s)

Outcome

Year

Ref.

Poor sleep quality linked to elevated WBC rather than NSW itself

WBC (blood)

↑ Systemic inflammation (sleep-mediated)

2007

139

Circadian disruption induces leukocytosis

Total leukocytes (blood)

↑ Systemic inflammation

2007

140

No sustained inflammatory changes with rotational NSW

CRP, ILs, immune cell profile (blood)

↔ No significant effect

2011

106

Multi-shift work increases CRP and WBC (reversible after cessation)

CRP, WBC (blood)

↑ Mild systemic inflammation

2011

141

Elevated IL-6, CRP, WBC, neutrophils, lymphocytes, platelets

Multiple inflammatory markers (blood)

↑ Systemic inflammation

2011

145

Higher hs-CRP and leukocyte count vs. day workers

hs-CRP, WBC (blood)

↑ Systemic inflammation

2016

142

Circadian misalignment amplifies alcohol-induced inflammation

LBP, LPS, IL-6 (blood)

↑ Basal inflammation, loss of rhythmicity

2016

143

NSW increases CRP and monocytes independent of CVD risks

CRP, monocytes (blood)

↑ Systemic inflammation

2017

144

Night-only work elevates IL-6 but not hs-CRP

IL-6, hs-CRP (blood)

↑ IL-6; ↔ hs-CRP

2018

148

Disrupted circadian variation in IL-6, partial for TNF/IL-1β

IL-6, TNF, IL-1β (saliva)

Altered cytokine rhythmicity

2019

149

CRP not elevated by NSW alone, but amplifies pain risk

CRP (blood)

↔ CRP; ↑ Pain risk (synergistic)

2021

150

Increased leukocytes, hs-CRP, and differential counts

hs-CRP, WBC, neutrophils, lymphocytes, monocytes (blood)

↑ Systemic inflammation

2022

151

Male NSW workers show higher GlycA (BMI-related)

GlycA (serum)

↑ Low-grade inflammation

2022

153

NSW elevates WBC, LBP, TNF-α, IL-10; impairs cytokine response

WBC, LBP, TNF-α, IL-10 (blood)

↑ Low-grade inflammation; ↓ cytokine responsiveness

2023

31

NSW and poor sleep ↑ BP, correlated with CRP, WBC, neutrophils

CRP, WBC, neutrophils (blood); BP

↑ Low-grade inflammation, ↑ BP

2023

147

Elevated hs-CRP and TLC; predictors include NSW, age, BMI

hs-CRP, TLC (blood)

↑ Systemic inflammation

2024

152

Low-grade inflammation mediates IBS risk (INFLA-score)

INFLA-score (5 biomarkers, plasma)

↑ IBS risk

2024

154

NSW increases psoriasis severity and IL-8

IL-8 (blood); psoriasis index

↑ Chronic inflammation

2024

156

NSW ↑ CAR and NLR vs. day workers

CAR, NLR (blood)

↑ Chronic low-grade inflammation

2025

124

NSW activates innate immune/inflammatory pathways (TLR/MyD88)

IL-1β, IL-2, IL-6, IFN-γ, CSF2 (blood)

↑ Cytokine activation

2025

146

NSW ↑ INFLA-score (CRP, PLT, WBC, NLR) mediating IBS risk

INFLA-score (blood)

↑ Low-grade inflammation; ↑ IBS risk

2025
