At present, there is no standard of treatment using systemic high-dose corticosteroids in cases of pregnant women with Vogt-Koyanagi-Harada (VKH) disease. Although high-dose systemic corticosteroid treatment is often used for VKH disease during pregnancy, it also poses a risk to the fetus.
A 29-year-old woman in the 34th week of pregnancy experienced bilateral metamorphopsia. She had been receiving 5 mg of prednisolone daily for the past 8 years as treatment for rheumatoid arthritis. In order to prevent progression of bilateral serous retinal detachment caused by VKH disease, we recommended the use of high-dose systemic corticosteroids but the patient refused. Thus, we administered only topical ophthalmic betamethasone for mild anterior uveitis. Surprisingly, however, the bilateral bullous retinal detachment healed in just 19 days after the onset of symptoms. A healthy baby was born 1 month later, and sunset glow fundus was subsequently observed without any recurrence of uveitis.
We report a case in which bilateral subretinal fluid caused by VKH disease in a young woman during late pregnancy resolved without high-dose corticosteroid treatment. Pregnancy may have had a beneficial effect on uveitis activity caused by VKH disease. To our knowledge, this report describes the shortest healing period for bilateral bullous retinal detachment in a pregnant woman with VKH disease.
KeywordsHigh-dose corticosteroids Pregnancy Vogt-Koyanagi-Harada disease
Although reports have described cases of pregnant women with Vogt-Koyanagi-Harada (VKH) disease [1–10], no standard of treatment that includes systemic high-dose corticosteroids has been established. Previously, a 24-year-old pregnant woman with VKH disease successfully healed on the 26th day after onset without the use of systemic or topical corticosteroids . Here, we report a 29-year-old pregnant woman who received prednisolone 5 mg/day for rheumatoid arthritis; she exhibited bullous retinal detachment caused by VKH disease, and the subretinal fluid successfully resolved in just 19 days after the onset of symptoms. To our knowledge, this report describes the shortest healing period for bilateral bullous retinal detachment in a pregnant woman with VKH disease.
On 12 November 2013, the patient returned, presenting with progressive vision loss in both eyes that had begun 4 days earlier. The patient’s BCVA was 0.3 in her right eye and 0.2 in her left eye. Ophthalmic examination revealed bullous retinal detachment in both eyes (Figs. 1 and 2, day 12). Intraocular pressures were 10 mmHg (right eye) and 11 mmHg (left eye). However, she continued to refuse treatment. At a subsequent visit on 19 November 2013, she reported visual improvement in both eyes. Ophthalmic examination on that day revealed the disappearance of subretinal fluid from both eyes (Figs. 1 and 2, day 19). Her BCVA was 0.8 in her right eye and 0.9 in her left eye. Intraocular pressures were 19 mmHg (right eye) and 16 mmHg (left eye). On 27 November 2013, she delivered a healthy female baby (gestational age 37 weeks and 5 days, 2294 g) by spontaneous vaginal delivery. The baby’s birth weight was low, but not small for her gestational age. A subsequent examination on 1 April 2014 revealed that the patient’s BCVA was 1.0 in both eyes, and examination of her fundus revealed typical sunset glow fundus, without subretinal fluid (Figs. 1 and 2, day 152). Intraocular pressures were 14 mmHg (right eye) and 10 mmHg (left eye). She exhibited alopecia and poliosis. After reviewing all of the patient’s clinical findings, we diagnosed her with complete VKH. On 11 May 2015, our final meeting with the patient, she did not exhibit any recurrence of VKH. The patient was still receiving 5 mg prednisolone daily for rheumatoid arthritis. Prior to and during her pregnancy, the patient’s blood pressure stayed within normal limits, and she never exhibited hypertension.
High-dose systemic corticosteroid treatment is often used for VKH disease during pregnancy [2–7, 10], although some reports indicate that it may also pose a risk to the fetus. In one such report, Ohta et al. described a case of fetal death in a 28-year-old Japanese woman who was being treated with intravenous high-dose prednisolone for VKH disease . In another report, Steahly detailed the adverse effects of high-dose corticosteroid treatment for VKH disease during pregnancy in two cases: one patient suffered a spontaneous abortion, and the other delivered a premature infant . Doi et al. also reported that a pregnant VKH patient treated with a high-dose systemic corticosteroid delivered a low-birth-weight infant with an epibulbar dermoid, lipodermoids, and preauricular appendages, although the relationship among VKH disease, systemic corticosteroids, spontaneous abortion, and congenital malformation was not clear . Østensen and Skomsvoll stated that, administered during early pregnancy, corticosteroids are also considered a risk factor for the development of oral clefts . In light of these potential complications, they have proposed that the daily dose should be kept to ≤15 mg during the first trimester. Miyata et al. suggested that treatment should be chosen according to the severity of inflammation, the stage of pregnancy, maternal condition, and fetal condition. In their report, successful treatment of three cases of VKH disease during pregnancy was demonstrated . One patient with mild inflammation was treated with a topical corticosteroid, while two additional cases were treated with a high-dose systemic corticosteroid. No abnormalities were observed during or after the deliveries.
The use of high-dose corticosteroids during pregnancy is associated with premature rupture of the membranes, intrauterine growth restriction, and the precipitation of maternal complications such as gestational diabetes, hypertension, osteoporosis, and avascular bone necrosis . It should be also noted that prednisone, prednisolone, and methylprednisolone have minimal placental transfer and are the drugs of choice during pregnancy. On the other hand, fluorinated corticosteroids such as dexamethasone and betamethasone easily cross the placenta and therefore should not be used unless there is intent to treat the fetus .
Although an early pregnancy flare-up is typical of VKH disease , pregnancy may have a beneficial effect on uveitis activity caused by VKH disease . Generally, during early pregnancy, cellular immunity is suppressed and the production of inflammatory cytokines is low, while corticosteroid production is high. Because of these immunological conditions, the inflammation caused by VKH disease during the first and second trimesters of pregnancy may be mild. Consequently, in our case, VKH disease may not have appeared during the first and second trimesters. In addition, the period of time required for bilateral absorption of the subretinal fluid was obviously shorter than in normal VKH patients, even without high-dose corticosteroid treatment. Steahly showed that some cases of VKH disease improved clinically during pregnancy after the discontinuation of corticosteroid treatment; however, symptoms recurred after their pregnancies ended . These findings suggest it might be unnecessary to administer more corticosteroid to treat persistent serous retinal detachment after systemic corticosteroid treatment.
The patient had received 5 mg prednisolone daily for the past 8 years as treatment for rheumatoid arthritis. It is unclear whether this daily oral administration of 5 mg prednisolone contributed to the resolution of VKH in this patient; however, we do not believe 5 mg of oral prednisolone is enough to resolve the active phase of VKH as shown in this case. The precise mechanism is not clear, as we did not investigate this patient’s serum hormone levels during pregnancy and neither did her gynecologist or rheumatologist.
In summary, we report a 29-year-old woman in the 34th week of pregnancy taking prednisolone 5 mg per day, who exhibited bilateral bullous retinal detachment as a result of VKH disease. Without administration of high-dose systemic corticosteroids, subretinal fluid resolved 19 days after the onset of symptoms, and uveitis did not recur thereafter. No standard of treatment has been established for pregnant patients with VKH disease. In the absence of systemic high-dose corticosteroid treatment, pregnancy may favorably influence and modulate the course of the disease, as exemplified by this patient.
We obtained written informed consent from the patient to publish this report and any accompanying images. Our own institute’s IRB also granted approval.
