What is the recommended dose and duration of high-dose corticosteroid for pulmonary hemorrhage?

Comment by InpharmD Researcher

Based on the available evidence, there is no single standardized dose or duration for high-dose corticosteroids in pulmonary hemorrhage, which might explain the variations in practice. While conventional regimens have used intravenous methylprednisolone pulses (500 mg to 2 g/day) for 3-5 days, emerging evidence questions the necessity of such high doses. In fact, recent studies in critically ill patients have found that lower-dose regimens (e.g., <250 mg/day of methylprednisolone) may be associated with lower ICU mortality, challenging the validity of traditional high-dose protocols.

Background

From a 2021 review, the conventional use of high-dose corticosteroids for diffuse alveolar hemorrhage (DAH), often initiated with intravenous methylprednisolone pulses (500 mg to 2 g/day) for 3-5 days, was being re-evaluated. While this regimen aims to suppress the acute inflammatory lung injury, its benefit, particularly in critically ill patients, remains undefined, and associated mortality remains high. Emerging evidence questions the necessity of such high doses, as one study found that patients treated with lower-dose methylprednisolone (<250 mg/day) had significantly lower ICU mortality compared to those on medium or high doses, without a difference in overall mortality. Furthermore, research in related conditions like ANCA-associated vasculitis shows that reduced-dose glucocorticoids are equally effective for mortality and reduce serious infections, challenging the validity of high-dose corticosteroid protocols for DAH. [1, 2]

In a paragraph within a 2021 review of acute alveolar hemorrhage without respiratory failure requiring mechanical ventilation, the typical initial regimen consists of prednisone at 0.5 to 0.75 mg/kg/day, not to exceed 60 mg per day, which is maintained for 4 to 8 weeks. Provided the patient shows symptomatic and radiologic improvement, the dose is then gradually reduced by 5 mg every other week until reaching 10-15 mg daily. The total duration of therapy is often extended, and if the disease remains well-controlled after 12 to 18 months, the corticosteroid can be slowly tapered until discontinuation. [3]

Low-, medium- and high-dose steroids with or without aminocaproic acid in adult hematopoietic SCT patients with diffuse alveolar hemorrhage
Design	Retrospective study N= 119
Objective	To evaluate the differences in mortality when patients are treated with varying doses of steroids with or without aminocaproic acid (ACA)
Study Groups	Steroids and ACA (n= 82) Steroids only (n= 37)
Inclusion Criteria	Consecutive adult patients admitted to the ICU between October 2007 and June 2011 who received intravenous steroid therapy on or after ICU admission for DAH
Exclusion Criteria	Age <18, or steroids ± ACA administration for non-DAH illnesses
Methods	Patients were stratified into groups based on treatment with steroids only or steroids with ACA. Within each group, patients were categorized based on the initial dose of methylprednisolone: low dose (<250 mg/day), medium dose (250–1000 mg/day), and high dose (≥1000 mg/day). Dosing for the first 5 days of therapy was measured. Data collection included patient demographics, ICU admission laboratory data, severity of illness scores, transplant-related characteristics, and mortality outcomes
Duration	October 2007 to June 2011
Outcome Measures	Primary: 30, 60, 100 day, ICU and hospital mortality
Baseline Characteristics		Low dose (n= 19)	Medium dose (n= 40)	High dose (n= 23)
	Age (years)	50.7 (±14.1)	44.6 (±13.6)	48.5 (±15.9)
	Male	42.1%	42.5%	82.6%
	Mean steroid dose (mg/day)	136.8 (±59.1)	437.5 (±91.2)	1000 (±0)
Results		Low-dose (n= 19)	Medium-dose (n= 40)	High-dose (n= 23)	P-value
	ICU mortality (%)	31.6	57.5	65.2	0.07
	Hospital mortality (%)	68.4	82.5	78.3	0.45
	Mortality by days (%) 30 60 100	47.4 73.7 84.2	77.5 85 92.5	65.2 78.3 87	0.07 0.55 0.59
Adverse Events	No significant differences in thrombotic complications such as deep vein thrombosis, pulmonary embolism, myocardial infarction, and ischemic stroke between groups.
Study Author Conclusions	Treatment strategies for DAH may need to be reanalyzed to avoid potentially unnecessary and harmful therapies. Medium- and high-dose steroids were associated with higher ICU mortality compared to low-dose steroids. Adjunctive treatment with ACA did not produce differences in outcomes.
Critique	The study's retrospective design limits the ability to establish causality. The potential for clinician bias in treating sicker patients with higher doses of steroids or ACA cannot be ruled out. The study highlights the need for prospective studies to better understand the optimal treatment strategies for DAH in critically ill patients.

Corticosteroid Therapy for Diffuse Alveolar Hemorrhage with Respiratory Failure in Hematologic Malignancies: A Retrospective Cohort Study
Design	Retrospective cohort study N= 44
Objective	To investigate the effectiveness of steroid therapy in hematologic malignancy patients who developed DAH with respiratory failure and required treatment in the intensive care unit (ICU)
Study Groups	Steroid group (n= 32) Control group (n= 12)
Inclusion Criteria	Adult patients (aged ≥18 years) with leukemia, lymphoma, or multiple myeloma who developed DAH with acute respiratory failure and were admitted to the ICU from August 2005 to May 2018
Exclusion Criteria	Patients who met the diagnostic criteria of DAH but were not admitted to the ICU
Methods	Patients were classified into steroid or control group based on steroid therapy. Steroid therapy included 1–2 mg/kg/day of intravenous methylprednisolone, with or without pulse therapy (500–1000 mg/day for 3 days). Data were collected retrospectively from electronic medical records.
Duration	August 2005 to May 2018
Outcome Measures	ICU mortality, change in PaO2/FiO2 ratio over the first 4 days
Baseline Characteristics		Control Group (n = 12)	Steroid Group (n = 32)
	Age, mean ± SD, years	55.5 ± 14.0	50.1 ± 15.4
	Sex, male, n (%)	7 (58)	17 (53)
	History of solid malignancy, n (%)	3 (25)	1 (3)
	History of hematopoietic stem cell transplantation, n (%)	1 (8)	11 (34)
Results		Control Group (n = 12)	Steroid Group (n = 32)	p-value
	ICU mortality, n (%)	8 (67)	21 (66)	0.948
	Change in PaO2/FiO2 ratio over the first 4 days, mean ± SD, mm Hg	19 ± 72	55 ± 79	0.169
Adverse Events	The proportions of patients who developed new infections within 28 days were comparable between the two groups (53% vs 50%, P >0.999)
Study Author Conclusions	Hematologic malignancy patients who developed DAH with respiratory failure and were admitted to the ICU had high mortality, irrespective of steroid therapy. Steroids may not improve the prognosis of DAH in these patients.
Critique	The study is limited by its retrospective design, small sample size, and single-center setting, which may affect the generalizability of the findings. The lack of a standardized protocol for steroid therapy could have influenced the results. Despite these limitations, the study provides valuable insights into the ineffectiveness of steroid therapy in improving outcomes for DAH in hematologic malignancy patients.

	Death before discharge	11/12	9/10	29/43	Not significant
Adverse Events	The incidence of infections was high (40%) but not significantly increased by corticosteroid treatment. No significant difference in the rate of bacterial, viral, or fungal infections among groups
Study Author Conclusions	High-dose corticosteroid therapy for diffuse alveolar hemorrhage related to bone marrow transplantation was associated with improved total survival and survival to hospital discharge, and decreased development of respiratory failure. Further prospective studies are warranted to verify the effectiveness of the treatment.
Critique	The study's retrospective design limits the ability to establish causality. The lack of randomization and potential selection bias due to the disparity in group sizes may affect the generalizability of the findings. However, the study provides valuable insights into the potential benefits of high-dose corticosteroid therapy in this patient population.
