Abstract (2. Language):
Systemic lupus erythematosus (SLE) rarely causes atrioventricular (AV) conduction disorders in adults including
first- and second-degree bundle branch blocks and complete heart block. This report will present a case of seconddegree
AV block with anti-RNP and anti-Ro antibodies, an early sign of SLE, which improved with a standard dose
of steroids. A fifty-nine-year-old woman presented with tiredness lasting for about one month. History did not
reveal any cardiac illness. She was a non-smoker. On physical examination, she had a blood pressure of 120/80
mmHg, a rhythmic cardiac pulse of 62/min and a rhythmic radial pulse of 62/min. She had malar rash and oral aphthae.
Cardiac oscultation did not reveal a cardiac murmur. Electrocardiography (ECG) showed Mobitz type I block,
a second degree AV block. Antinuclear antibodies (1/1000) were in granular shape and anti-Sm and anti-Ro antibodies
were positive. Anti-RNP antibodies (1/600) were also positive. The diagnosis of SLE was based on oral aphthae,
malar rash, proteinuria and ANApositivity. Methyl prednison 1mg/kg was instituted. The patient noted that her
fatigue subsided on the fifth day of the treatment and her ECG was normal.
Although anti-Ro and anti-RNP antibodies are known to be positive in neonates with AV block, adults with anti-Ro
and anti-RNP positivity should also be followed carefully for heart blocks.

Abstract (Original Language):
Dal bloklar›, birinci, ikinci derece ve tam kalp blo¤unu içeren atriyoventriküler (AV) iletim bozuklu¤u, eriflkin sistemik
lupus eritematozusta (SLE) nadiren görülür. Burada standart doz steroid ile düzelen SLE erken bulgusu olarak
de¤erlendirdi¤imiz, Anti RNP, Anti-Ro antikorlar› pozitif 2. derece AV bloklu hastay› sunuyoruz.
Ellidokuz yafl›nda bayan yaklafl›k 1 ayd›r olan yorgunluk yak›nmas› ile baflvurdu. Soy ve özgeçmiflinde kardiyak
hastal›k dahil özellik tariflemiyordu. Sigara içmiyordu. Muayenesinde kan bas›nc› 120/80 mmHg, kardiyak nab›z
62/dk ritmik, radiyal nabz› 62/dk ritmik idi. Malar rash, oral aftlar› vard›. Kalp oskültasyonunda üfürüm duyulmad›.
Elektrokardiyografisinde (EKG) 2. derece atriyoventriküler Mobitz tip 1 blok tespit edildi. Antinükleer antikor
1/1000 granüler paternde, anti Sm, Ro antikorlar› pozitif tespit edildi. Anti-RNP antikorlar› 1/600 oran›nda pozitifti.
Oral aft, malar rash, proteinüri, ANApozitifli¤i ile SLE tan›s› kondu. Metil prednison 1mg/kg baflland›. Tedavinin
5 gününde yorgunlu¤u azalan hastan›n EKG’si normaldi.
Özellikle neonatalde iyi bilindi¤i gibi anti-Ro, anti-RNP antikorlar› pozitif tespit edilen eriflkin hastalar kalp bloklar›
aç›s›ndan takip edilmelidir.
