Pneumocystis pneumonia after use of corticosteroids in a man with severe alcoholic hepatitis

Rationale Severe alcoholic hepatitis (AH) has a very high mortality rate. Current guidelines recommend oral corticosteroids as first-line agents in individuals with severe AH to reduce short-term mortality. However, systemic corticosteroids have serious adverse effects. In individuals with AH, infection, which is one of the complications of steroid use, can result in serious outcomes, such as acute-on-chronic liver failure. Pneumocystis pneumonia (PCP) is a life-threatening opportunistic infection which may occur when high-dose corticosteroids are prescribed for more than 1 month. Therefore, when high-dose corticosteroids are used, providing PCP prophylaxis is warranted. Although trimethoprim-sulfamethoxazole (TMP-SMX) is the drug of choice for the prophylaxis of PCP, its hepatotoxicity limits its use in patients with severe AH who are on high-dose corticosteroids. Moreover, there is a lack of consensus on which drugs should be used for PCP prophylaxis in individuals with severe AH who are on glucocorticoid treatment. Herein, we report a case of a 43-year-old male with fatal PCP that occurred after the use of corticosteroids for severe AH. Patient concerns A 43-year-old alcoholic man presented with a hematoma on his right leg. His liver function was poor, and he was he was diagnosed with severe AH and treated with oral corticosteroids for 26 days. After glucocorticoid treatment, he developed a productive cough. Diagnoses A sputum PCR test was positive for Pneumocystis jirovecii. Interventions He was initially treated with TMP-SMX and required artificial ventilation. Outcomes He developed disseminated intravascular coagulation and multi-organ failure, and died 10 days after starting TMP-SMX. Lessons To date, prevention of PCP in individuals with severe AH who are on corticosteroids has been overlooked. This case illustrates the need for prophylaxis of PCP in individuals with severe AH taking corticosteroids.
