NCT06499233

Brief Summary

This is an open-labeled, prospective clinical study aims at collecting and analyzing baseline characteristics of autoimmune inflammatory rheumatic disease (AIIRD) patients receiving sulfanilamide for preventive purposes, as well as subsequent follow-up data, in order to assess the efficacy and safety of the medication. Additionally, through a stratified analysis of risk factors, the investigators aim to identify the AIIRD population that would benefit most from preventive medication based on a favorable benefit-risk ratio.

Outcome Measures

Primary Outcomes (1)

  • Number of participants with PJP infection

    Defined as documentation/diagnosis of Pneumocystis from a properly obtained specimen (induced sputum, bronchoalveolar lavage, or biopsy) in a patient with clinical manifestations compatible with PJP.

    6 months, 12 months

Secondary Outcomes (3)

  • TMP/SMZ related adverse drug reactions

    6 months, 12 months

  • PJP-related mortality

    6 months, 12 months

  • All cause mortality

    6 months, 12 months

Study Arms (4)

TMP/SMX (with PJP high risk)

EXPERIMENTAL

AIIRD patients who have PJP high risk and receive prophylactic Trimethoprim/ Sulfamethoxazole (TMP/SMZ) treatment; Drug intervention: Patients receive Trimethoprim/Sulfamethoxazole (TMP/SMX) 480 mg p.o. every day as PJP Prophylaxis.

Drug: Trimethoprim/Sulfamethoxazole

no TMP/SMX (with PJP high risk)

NO INTERVENTION

AIIRD patients who have PJP high risk and do not receive prophylactic Trimethoprim/ Sulfamethoxazole (TMP/SMZ) treatment.

TMP/SMX (with PJP low-risk)

EXPERIMENTAL

AIIRD patients who have PJP low risk and receive prophylactic Trimethoprim/ Sulfamethoxazole (TMP/SMZ) treatment; Drug intervention: Patients receive Trimethoprim/Sulfamethoxazole (TMP/SMX) 480 mg p.o. every day as PJP Prophylaxis.

Drug: Trimethoprim/Sulfamethoxazole

no TMP/SMX (with PJP low-risk)

NO INTERVENTION

AIIRD patients who have PJP low risk and do not receive prophylactic Trimethoprim/ Sulfamethoxazole (TMP/SMZ) treatment.

Interventions

Patients received Trimethoprim/Sulfamethoxazole (TMP/SMX) 480 mg p.o. every day as PJP Prophylaxis; Treatment duration: at least 28 days, adjusted by the clinician based on the severity of the patient's condition, the patient's tolerance to the drug and treatment willingness).

Eligibility Criteria

Age18 Years+
Sexall(Gender-based eligibility)
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The patient was diagnosed with AIIRD according to the International Classification of Diseases and had received steroids or immunosuppressive therapy;
  • The patient had not received standard PJP treatment before enrollment, including the first-line treatment drug TMP/SMZ, or other second-line treatment drugs (including Pentamidine, Atorvastatin, Caspofungin, etc.);
  • The patient was at least 18 years old at the time of enrollment;

You may not qualify if:

  • Serious health problems or diseases, including (but not limited to) the following: severe liver damage (ALT, AST elevated above normal value by more than 5 times), severe renal insufficiency (GFR \< 30mL/min or Scr \> 445umol/L), severe myelosuppression (Hb \< 65g/L, PLT \< 25×10\^9/L or neutrophils \< 0.5×10\^9/L);
  • Screening test indicates infection with human immunodeficiency virus (HIV), history of lymphomatous hyperplasia of the lymphatic tissue or any malignant tumor of any organ system within the past 5 years, or history of organ transplantation;
  • Participants with a history of allergy to sulfonamide drugs, megaloblastic anemia due to folate deficiency;
  • Pregnant and lactating women;
  • Any medical or psychological condition that the investigator believes would interfere with the participant's ability to comply with the protocol or complete the study;
  • Patients who refuse to comply with the requirements of this study and complete the study;
