Case ReportAbstract
Rheumatoid arthritis (RA) is a common autoimmune multi-systemic inflammatory disease affecting joints result in dysfunction and ultimately damage. Bronchiectasis (BR) is a long-term pulmonary condition that is characterized by permanent dilation of the bronchial, the association of RA and BR has been recognized since the past five decades. This is the first reported document arthropathy in a female patient with bronchiectasis in Sudan. We aim to bring attention to the uncommon presentations and challenge of diagnosing patients of BR with RA. We are presenting 48 years old female complaining of chronic cough, chest pain and multiple joints pain. examination showed Tender joints, Z-shape thumbs appearance figure and hyper flexed DIP deformity in index fingers. chest auscultation reveals bilateral Coarse crackles disappears after coughing. Chest CT scan showed features suggested the diagnosis of BR, Anti-ccp positive, rheumatoid factor IgM, all indicate a diagnosis of RA in addition, the patient has low serum Vitamin D. Patient received hydroxychloroquine, Mycophenolate mofetil, vitamin D and calcium supplements and her general condition is improved.

Introduction
RA is a common autoimmune multi-systemic inflammatory disease affecting joints result in dysfunction and ultimately damage. It is affecting 1-2% of the population worldwide [1]. The disease has a remarkable effect on women more than men by two to three-time [2]. It also has an extra-articular manifestation which may affect other system and organs such as eye, skin, vasculitis, cardiovascular and pulmonary disease. Development of this feature may a indicate high risk of morbidity and premature death [3], pulmonary involvement is unfrequented and difficult to detect clinically, hence the pleural disease is common but asymptomatic, studies reporting involvement in 50% of cases with 10% detection [4], also RA has been known to be a cause of BE in the prevalence of 3% in RA cohort [5]. In Sudan a lot of cases have been misdiagnosed due to low recognition of the disease in its early stage. This case report is the first one to document arthropathy in a female patient with bronchiectasis as presentation in Sudan. We believe that it will focus doctors’ attention on the uncommon presentations and challenge of diagnosing patients with bronchiectasis.
Case Presentation
We are reporting a case of 48 years old female primary school teacher, with 5 children, married for 20 years, residents at Algaily at Khartoum north state, Sudan. Her medical history in the past is clear, had no smoking history, she was healthy and well until 3 years ago, she started to endure from a cough, which was lasting through all the day, productive with whitish small amount odourless sputum, not associated with fever or sweating, stationary in its course lasting for more than 4 months then she sought medical attention, as Sudan is a pandemic area for tuberculosis, initial workup for TB clinically and laboratory was done but clear and the investigation reveals no evidence of infection. Then she retained back again seeking for medical care at chest physician, the auscultation reveals Coarse crackles disappear after coughing on both sides of the chest at middle and lower zones, in addition to localized chest pain not radiated and associated with vomiting. He asked for furthermore workup, based on clinical features along with chest CT scan which showed there were bilateral septal thickening, ground-glass opacity mild bronchiectasis changes. he put his diagnosis as Bronchiectasis (Figure 1).
Figure 1: CT chest of the patient, shows bilateral septal thickening, ground-glass opacity mild bronchiectasis changes.
The patient has received antibiotics, prednisolone and cough syrup and her condition get improved. Ten months later after she received her treatment, the patient developed multiple joints pain including hands at metacarpophalangeal (MCP) joints, proximal interphalangeal (PIP) joints, Wrist joints, elbow joints, upper neck and lower back, knees and feet joints. It is often getting worse in the mornings and after she finished her ordinary daily activity, there is swelling mainly at small joints. The first episode was so severed but remitted spontaneously, after 6 months another episode appeared but less in the severity of the first attack and it affecting the same joints, after she asked medical attention again, the patient was referred to Rheumatologist, during examination patient showed Tender MCP, PIP, Z-shape thumbs appearance Figure 2, hyperflexed deformity in index fingers (Figure 3), Full workup profile was done, investigation showed patient had Anti-ccp positive as well as rheumatoid factor IgM positive (Table 1), diagnosed with Rheumatoid Arthritis based on clinical manifestation and laboratory findings. Moreover, this patient has a remarkable vitamin D level deficiency. Patient received hydroxychloroquine 200 mg BD, Mycophenolate mofitel acid 500 mg tabs BD and calcium supplements, Vitamin D tab 50000 once per week for three months, symbicort inhaler and Vitaferrol Cap (iron tonics) daily for 3 months. The patient now in well condition and on regular follow up.

Discussion
Rheumatoid arthritis has a strong association with a lot of pulmonary conditions, such as Tuberculosis, pleural effusions, bronchiolitis and BR [6]. The association of RA and BR has been recognized earlier, with the first published report in 1960 [7]. Bronchiectasis is a long-term condition that is characterized by permanent bronchial dilation [8]. The presented patient endure the clinical features of the disease such as sputum production, cough and repeated infections, In addition, CT chest done to the patient showed bilateral septal thickening and ground-glass opacity mild bronchiectasis changes (Figure 1), high resolution CT scan of the chest is considered as the gold standard for confirmation of bronchiectasis [9]. forced vital capacity [FVC], lung function test, sputum bacteriological culture and chest radiograph can also be needed to establish a proper diagnosis [10].Others differential respiratory illnesses such as TB has been laboratory excluded.
The association between BR and RA has not clearly been suggested, the defining cause of the complication is not clearly known [11]. Some reports speculated that RA or its therapy may increase the risk of respiratory infection, leading to BR, Although, the onset of BR often precedes RA as in our presented case [12]. Rheumatoid arthritis is a disease of progressive inflammatory course ended with disability, pain, and sometimes mortality [13]. RA clinically presented with tenderness Involvement of small joints associated with swelling in a symmetrical pattern and abnormal value of autoantibodies such (anti-CCP), rheumatoid factor (RF) and high ESR [14]. The presented case is a classical presentation of RA as it complains of multiple joints pain including hands at metacarpophalangeal (MCP) joints, proximal interphalangeal (PIP) joints, Wrist joints, elbow joints, upper neck and lower back, knees and feet joints. The Patient also showed Tender MIP, PID, Z-shape thumbs appearance, The laboratory investigations revealed high ESR with rheumatoid factor IGM positive with anti-CCP positive (Table 1).
The patient lab works show low level of Vitamin D (low serum 25-hydroxyvitamin D (25OHD), as many other reports have linked this condition to RA as a risk factor, however, the causal role for Vitamin D in RA is yet unclear, with conflicting data from many previous reports [15].
Conclusion
A Sudanese female, presented with multiple joints pain and chronic cough, chest CT scan revealed a presence of BR, more clinical and lab results confirm a diagnosis of RA in the presence of BR. The Patient received hydroxychloroquine, Mycophenolate mofitel acid, calcium supplements,Vitamin D, symbicort inhaler and Vitaferrol Cap (iron tonics). Now patient is in well condition. The case was diagnosed and treated by Dr Ziryab Imad Taha, Rheumatology department at Haj alsafi teaching hospital, Bahri, Khartoum, Sudan and Dr. Asma Elhaj Ibrahim Abdulgadir, Respiratory Medicine department at Alshaab Teaching hospital, Khartoum, Sudan.
