RESUMEN
INTRODUCTION: Granulomatosis with polyangiitis (GPA), formerly termed Wegener's granulomatosis, is an autoimmune disease marked by necrotizing granulomatous inflammation and vasculitis affecting small-sized vessels. It commonly impacts the renal and respiratory systems. MATERIALS AND METHODS: This retrospective case series sampling conducted in a tertiary care hospital between May 2023 and April 2024 examined six newly diagnosed GPA patients who were proteinase 3 cytoplasmic-antinuclear cytoplasmic antibody (PR3 c-ANCA) positive and had concurrent respiratory infections. None of them had any prior immunosuppressive conditions. The age range was 18-47 years with a mean of 35.0 (standard deviation: 11.83). All the patients had pneumonia (N=6, 100%). Out of all, five had bacterial pneumonia (N=5, 83.3%) and one had tuberculous pneumonia (N=1, 16.7%). A high level of PR3 c-ANCA (>150 RU/mL) was noted in four patients (N=4, 66.7%). Common symptoms included dry cough (N=5, 83.3%), loss of weight and appetite (N=2, 33.3%), and fever (N=2, 33.3%). Three patients had otitis media and/or nasal polyposis (N=3, 50%). Two patients (N=2, 33.3%) with life-threatening organ dysfunction were given concurrent antibiotics and steroids; the antibiotics were later modified based on culture and sensitivity results. One of these patients received antituberculosis therapy as Mycobacterium tuberculosis (MTB) was detected after 27 days of incubation in mycobacterial growth indicator tube broth. The remaining four patients (N=4, 66.7%) received antibiotics initially for 5-7 days until clinical resolution of pneumonia. Ultimately, they all showed clinical and radiological resolution (N=6, 100%) within 3-6 months of treatment. RESULTS: The patients exhibited constitutional symptoms such as fever and weight loss; lower airway disease symptoms including dry cough and hemoptysis; nasal and ear disease symptoms like epistaxis, ear pain, and ear discharge; and a renal disease symptom, hematuria. Computed tomography of the thorax revealed bilateral consolidations, most of which were cavitating. Bronchoalveolar lavage cultures grew Escherichia coli, Burkholderia cepacia, Pseudomonas aeruginosa, Klebsiella pneumoniae, and MTB, whereas pus swab cultures from otitis media grew Pseudomonas aeruginosa, Staphylococcus aureus, and coagulase-negative staphylococci. DISCUSSION: This study highlights the therapeutic challenges of GPA complicated by concurrent infections. Patients exhibited typical GPA signs, confirmed by PR3 c-ANCA levels. Concurrent infections require cautious antibiotic treatment before starting immunosuppressive therapy, except in life-threatening organ dysfunction. A unique case presented with both tuberculosis and GPA. Tailored treatment regimens combining antibiotics and immunosuppressives, including corticosteroids, methotrexate, and rituximab, resulted in clinical and radiological improvement in all the patients within 3-6 months. The addition of co-trimoxazole reduced the incidence of non-severe GPA relapses. CONCLUSION: Tailored treatment plans addressing both infectious and autoimmune aspects are essential for optimal care in GPA complicated by concurrent infections. This study highlights the need for a multidisciplinary approach involving pulmonologist, rheumatologist, microbiologist, and pathologist in the diagnosis and treatment of GPA, emphasizing the importance of individualized treatment plans tailored to the specific clinical scenario.
RESUMEN
INTRODUCTION: Inappropriate visits (IVs) and overcrowded emergency departments (EDs) can result in many complications for patients and medical staff. This study aimed to assess the incidence, associated factors, and predictive factors of IVs to ED. METHODS: This retrospective cohort single-center study was conducted in the ED of King Abdulaziz Medical City, Jeddah, Saudi Arabia. All ED visits in February 2023 were included. They were considered appropriate if the patient required investigation tests, underwent a procedure, was admitted to an inpatient ward, was admitted to the short-stay unit, was referred for follow-up at a specialist outpatient clinic after discharge from the ED, or was referred to the ED of another hospital. Failure to have at least one of these factors led to the visit being considered inappropriate. RESULTS: A total of 5,429 visits were included. The incidence rate of IVs was 1128 (20.7%). Of the visits, 1,028 (18.9%) were attended by patients aged <10 years, and 2,825 (52.0%) by female patients. The most reported complaints were pulmonological in 1,029 visits (18.9%). Patients with appropriate visits (AVs) had significantly higher median BMI scores than those with IVs (25.9 (20 - 3) vs. 23.7 (16.36 - 29), P = <0.0001). Visits with pulmonological (447 (39.6%) vs. 582 (13.5%)) and otorhinolaryngologic (54 (4.7%) vs. 94 (2.1%)) complaints were significantly more likely to be inappropriate (P = <0.0001). In multiple logistic regression, being a male (OR: 1.3, CI: 1.1 - 1.5, P = <0.0001), being non-Saudi (OR: 2.7, CI: 2.0 - 3.6, P = <0.0001), and visiting on the weekend (OR: 1.1, CI: 1.0 - 1.3, P = 0.0366) were significantly predictive of the visits being inappropriate. CONCLUSIONS: Our findings revealed a high incidence of IVs in the ED, with several factors predictive of IVs. Highlighting these factors can help minimize the incidence of IVs and, therefore, improve the quality of healthcare delivered to patients in need and their clinical outcomes.
