简要总结
The treatment guidelines for Pneumocystis pneumonia (PCP) suggest adding 40mg of prednisone (or its equivalent in methylprednisolone) twice per day on days 1 through 5, 40 mg days 6 through 10, and 20 mg daily on days 11 through 21 in subjects with moderate and serious PCP. Steroids have shown to improve clinical outcome and reduction in mortality in HIV-infected patients the effectiveness of adjuvant steroid treatment for PCP has been observed if it starts within the first 24 to 48 hours. Possibly, there is a long-term benefit with their use in the recovery of function and limitation of chronic pulmonary complications; recently, benefits have been observed in decreasing the incidence of Inflammatory Immune Reconstitution Syndrome (IRIS) due to Mycobacterium tuberculosis. On the other hand, steroids could increase the morbidity related to adverse reactions as well as paradoxical worsening of associated herpes virus infection, which are attributed to IRIS or as a result of immunosuppression generated by their use. Recently, it has been shown that gradually steroids withdrawal is not necessary in patients who have received less than 21 days of treatment.
This non-inferiority work aims to confirm the null hypothesis that a reduced steroid scheme in patients with moderate PCP (8 days) and severe pneumonia (14 days) is sufficient to limit long-term ventilatory complications and acute postinflammatory syndrome, compared to the conventional 21-day scheme. It also has been hypothesized that it could be associated with fewer cases of IRIS due to herpes virus type 1,2,3 and 8.
详细描述
The investigators selected hospitalized subjects with confirmed or suspected moderate or severe PCP: the diagnostic certainty will be based on the following criteria:
Proved PCP. Defined as cases with presence of P. jirovecii cysts in bronchial alveolar lavage (BAL) exams or lung biopsy.
Possible PCP. Defined by the following two criteria: 1) the presence of three of four items: cough, fever, dyspnea and compatible radiological or tomographic findings 2) associated clinical improvement after the onset of trimethoprim/sulfamethoxazole (TMP / SMX).
Probable PCP. Defined as the presence of one of the two previous criteria, without other identified microorganisms.
The radiological or tomographic findings compatible with PCP are: presence of bilateral reticular infiltrate, ground glass, crazy paving pattern and presence of bullae, cysts or spontaneous pneumothorax.

入选标准
- •Older than 18 years
- •To have a gasometry at the admission that confirms moderate or severe PCP.
- •Patients receiving trimethoprim / sulfamethoxazole in doses of 15 to 20 mg / kg per day from the first 24 hours after admission.
- •Patients who have begun adjuvant treatment with steroids in the first 48 hours after admission.

排除标准
- •Allergic to TMP/SMX, who have not tolerated desensitization.

研究组 & 干预措施
Group A conventional steroid regimen
Subjects will receive the conventional steroid regimen with prednisolone or equivalent (with methylprednisolone): Day 1 to 5: 40 mg orally every 12 h; Day 6 to 10: 40 orally every 24 hours; and Day 11 to 21: 20 mg orally every 24 h.
干预措施: Conventional steroid regimen (Drug)
Group B shortened steroid regimen
Subjects will receive the shortened steroid regimen for the severity of pneumonia with prednisone or equivalent with methylprednisolone, depending the severity of pneumonia:
- Moderate PCP. 40 mg orally every 12 h (Day 1 to 5);40 mg orally every 24 hours (Day 6 to 8).
- Severe PCP. 40 mg orally every 12 h (Day 1 to 5),40 mg orally every 24 hours (Day 6 to 10); and 20 mg orally every 24 h (Day 11 to 14).
干预措施: Shortened steroid regimen (Drug)
