ABSTRACT

To investigate clinical characteristics of muscular sarcoidosis presenting muscle mass as initial symptom. The clinical data of 10 patients diagnosed with muscular sarcoidosis and admitted in the Second Affiliated Hospital of Zhejiang University School of Medicine from May 2014 to October 2020 were collected and retrospectively analyzed. All patients were female, including 2 patients with unilateral involvement of lower extremities, 7 patients with bilateral involvement of lower extremities, and 1 patient with bilateral involvement of upper and lower extremities. Lung lesions were presented in all patients, and 9 cases had mediastinal lymphadenopathy. Serum angiotensin-converting enzyme (sACE) was 57-118 IU/ml. No specific characteristics were found by ultrasound. Typical “dark-star” sign and “three-stripe” sign were shown in the magnetic resonance imaging (MRI). The pathology of striated muscle was non-necrotizing granulomatous inflammation. Three patients were not treated. In 7 patients treated with prednisone 0.5-1 mg ·kg -1·d -1, immunosuppressants were combined in 3 patients at initial and the other 4 patients later on. During the follow-up of 7-62 months, 1 patient was stable, 6 improved and 3 relapsed. Till now, 5 patients are still on the treatment of glucocorticoid and immunosuppressant.

ABSTRACT

Objective To investigate the clinical characteristics of bronchopulmonary amyloidosis secondmy to primary Sj(0)gren's syndrome (pSS).Methods One patient in our series and 42 patients in the literatures were analyzed.The clinical manifestations,imaging features,diagnosis,treatments and prognosis of these patients were described respectively.Results Among the 43 cases,42 patients were female (98%).The median age was 57 (range 29-79) years.The diagnosis of bronchopulmonary amyloidosis was made subsequently to that of pSS with a median delay of 8.9 (range 0-30) years.Thirty-eight cases (88%) were localized amyloidosis.Most cases were related to AL amyloidosis (21/28,75% ).The main clinical manifestations included cough (18/38,47%),short of breath (13/38,34% ),sputum (9/38,24%) and hemoptysis (5/38,13% ).Nine patients (9/38,24% ) had no clinical symptoms.The most common patterns of radiological manifestations included multiple nodules (40/43,93%),multiple cysts or bullae (16/43,37%),interstitial lung disease (16/43,37% ),irregular luminal narrowing and airway wall thickening (8/43,19% ).The pulmonary function test was done in 17 patients,which revealed moderate to severe reduced diffusion capacity for carbon monoxide (8/17,47% ).The diagnosis of amyloidosis was made based on pathological findings in all cases.Pathologic examination showed diffuse deposits of amorphous,eosinophilic,Congo-red positive staining material.The treatments were symptomatic.The prognosis of most patients was good.The median follow-up time was 26.5 (range 2-96) months,only 2 patients died during the follow-up.Conclusion The bronchopulmonary amyloidosis secondary to pSS is localized amyloidosis in most cases.Clinical manifestations depend on the location and extent of airway lesions.The appearance of multiple lung nodules with calcified or cysts in chest images should be considered as secondary amyloidosis.No specific therapy is available for these cases,however,this condition in majority of patients progresses slowly.

ABSTRACT

Objective To evaluate the efficacy and safety of etoricoxib and meloxicam in the treatment of patients with acute gout. Methods A randomized,active comparator study was conducted at outpatients and inpatients in our hospital from January 2009 to July 2010.A total of 84patients aged (63.7± 11.0) years with an acute attack of gout were treated with etoricoxib 120 mg/d (n =48),or meloxicam 15 mg/d (n =36) for 7 d.The patient's assessment of joint pain (0- 4 point Likert scale) at drug treatment for 2-5 d was considered as the primary efficacy end point,4 h after firstly takiug the drug and 2-8 d after treatment as the secondary efficacy end point.The starting efficacy was determined until pain relieved by patient himself. The safety was assessed by adverse experiences and indexes including leucocyte, platelet,crcatinine, uric acid,alanine transaminase (ALT),aspartate transaminase (AST) and mean artery pressure(MAP). Results In 84 patients,3cases (8.3%) in meloxicam treatment and 15 cases (31.2%) in etoricoxib treatment (among which 13 cases finished treatment) discontinued therapy.The improvement scores of joint pain were (-0.41 ±0.35 vs.-0.19±0.30,P=0.005) at4 h after firstly taking the drug,(-1.66±0.58 vs. 1.38±0.44,P=0.018)at drug treatment for 2 -5 d,( - 1.83 ± 0.60 vs.- 1.85 ± 0.53,P=0.9) at 2 8 d after treatment,and (-2.64±0.45 vs. - 2.38±0.37,P=0.000) post-treatment higher than pre treatment.The starting time of pain relieving were (4.0 ± 4.6) h in etoricoxib treatment and (12.1±5.7) h in meloxicam treatment. The levels of leucocyte were decreased after treatment as compared with before treatment in both two drug treatments(P<0.05),while no differences were found in platelet.creatinine,uric acid,ALT and AST.MAP after etoricoxib treatment was increased compared with pretreatment ( P < 0.05 ). Drug related adverse experiences appeared in 15 cases (31.2 % ) in etoricoxib treatment and 12 cases(33.3 % ) in meloxicam treatment(P=1.000).The ratio of gastrointestinal tract-related adverse effects in meloxicam treatment was higher than in etoricoxib (22.2% vs.6.2%,P< 0.05),while adverse effects on cardiovascular in etoricoxib treatment were comparable to that of meloxicam (16.7 % and 11.1 %,P>0.05). Conclusions Etoricoxib at a dose of 120 mg once daily may be more effective than meloxicam for acute gout in aspects of safety and tolerance.

ABSTRACT

Objective To analyze the death causes of of dermatomyositis(DM)and polymyositis(PM)patients with interstitial pneumonia.Methods A retrospectively analysis of the clinical and laboratory characteristics of 15 dead DM and PM patients with interstitial pneumonia was carried out,and 23 survivors served as controls.Results The age of the dead group was(50.1?12.0)years old,and 12(80%)patients died within the six months after onset.The mortality was higher in the acute or subacute interstitial pneumonia patients than that in the chronic patients.With longer course of the disease,lung infections became the major cause of death.Significantly higher serum lactate dehydrogenase,glutamate- pyruvate transaminase,glutamic-oxalacetic transaminase levels were found in the dead group.The dead group had higher incidence of dyspnea and“Velcro”-like crackles and louer arterial oxygen pressure.The elevation of lactate dehydrogenase indicated worse prognosis.The elevation of creatine kinase and anti Jo-1 antibody werent the death causes. Conclusion The early onset of interstitial lung disease and lung infection were the major death causes in dermatomyositis and polymyositis patients.The earlier treatment of pneumonia-may improve the prognosis and reduce mortality.
