Pharmacological Methods to Increase White Blood Cell Count
Several medications have been shown to effectively increase white blood cell (WBC) counts. Mavorixafor, an oral CXCR4 antagonist, has demonstrated the ability to raise total WBCs and their subsets (neutrophils, lymphocytes, monocytes) by 1.5- to 3-fold in various patient populations, including those with WHIM syndrome, Waldenström's macroglobulinemia, and clear cell renal cell carcinoma. These increases were rapid, sustained during chronic treatment, and accompanied by a reduction in infection rates, especially in patients with pre-existing low WBC counts. Mavorixafor was generally well tolerated, both alone and in combination with other therapies .
Another agent, 12-O-tetradecanoylphorbol-13-acetate (TPA), administered intravenously, has been shown to increase depressed WBC and neutrophil counts in cancer patients who had previously received cytotoxic chemotherapy. WBC and neutrophil counts nearly doubled within a few days of TPA infusion, with effects lasting at least three days and only mild, reversible side effects reported .
Corticosteroids are also known to cause a significant, dose-dependent increase in WBC count. In hospitalized patients without infection or immune dysfunction, high-dose steroids led to an average WBC increase of up to 4.84 × 10⁹/L within 48 hours. The effect was less pronounced with lower doses .
Pegbovigrastim, a granulocyte colony-stimulating factor analog, has been shown to increase WBC, neutrophil, lymphocyte, and monocyte counts in dairy cows, regardless of parity or body condition. While this study was in animals, it supports the general principle that colony-stimulating factors can boost WBC counts .
Dietary and Lifestyle Factors Affecting White Blood Cell Count
Dietary intake can influence WBC counts. Higher vitamin B1 intake has been associated with increased WBC counts in adults, suggesting that certain nutrients may help modulate immune function .
Lifestyle factors also play a role. Disrupted circadian rhythms, such as irregular sleep and activity patterns, are linked to higher WBC counts and increased inflammatory markers. Interventions that improve circadian rhythm—such as maintaining regular sleep and activity schedules—may help regulate WBC levels and reduce inflammation .
Smoking and White Blood Cell Count
Cigarette smoking is a well-established cause of elevated WBC counts. However, this effect is reversible: quitting smoking leads to a significant decrease in WBC and neutrophil counts within one year, and these lower levels are maintained for at least two more years. Thus, smoking cessation is an effective way to normalize elevated WBC counts in healthy adults .
Conclusion
There are several ways to increase white blood cell counts, including pharmacological agents like mavorixafor, TPA, corticosteroids, and colony-stimulating factors. Dietary factors, such as vitamin B1 intake, and lifestyle interventions that support healthy circadian rhythms may also play a role. Conversely, quitting smoking can help reduce abnormally high WBC counts. The choice of intervention should be tailored to the underlying cause of low WBC counts and the individual’s overall health status.
