Discoid lupus in antiphospholipid syndrome: case description and literature review.

OBJECTIVE: The aim of the study was to report about a patient with discoid lupus erythematosus (DLE) who developed antiphospholipid syndrome (APS) 12 years after DLE diagnosis and review related literature. PATIENTS AND METHODS: This is a case report of a 34-year-old woman with DLE who developed APS. A review of articles published in the PubMed/MEDLINE, LILACS, and SciELO databases from 1966 to October 2020 was conducted using the following search terms: "antiphospholipid syndrome," "antiphospholipid antibodies," and "discoid lupus erythematosus" No language limitation was applied. RESULTS: Besides the present case, 5 case reports were identified. One case-control and two cross-sectional studies on antiphospholipid antibodies with or without APS in DLE were also reviewed. These studies revealed that APS can develop even 37 years after DLE was diagnosed. The case-control study found that patients with DLE have more anticardiolipin antibodies than controls. In contrast, one cross-sectional study showed a low prevalence of antiphospholipid antibodies in their group of patients, which was similar to findings in the general population. CONCLUSIONS: This study reviewed previous articles on DLE cases associated with antiphospholipid antibodies and/or APS, adding a new case description.

Thrombotic microangiopathy in primary antiphospholipid syndrome is linked to stroke and less deep venous thrombosis.

OBJECTIVE: To compare clinical and laboratory data obtained from patients with primary Antiphospholipid Syndrome (pAPS) with and without Thrombotic Microangiopathy (TMA). PATIENTS AND METHODS: A cross-sectional study with 66 (83.3% female) pAPS patients was performed. Demographic, clinical, drug use, antiphospholipid antibodies data were evaluated. Patients were subdivided into one of two groups: pAPS with TMA and pAPS without TMA and were compared. RESULTS: In this sample, 5/66 (7.6%) of patients had TMA. Primary APS with TMA group exhibited a higher frequency of arterial events (100% vs. 54.1%, p=0.02), stroke (100% vs. 32.8%, p=0.001) and a lower frequency of deep venous thrombosis (0 vs. 68.9%, p=0.0009) compared to the patients without TMA. Analysis of therapy used in these patients showed a higher frequency of current (40% vs. 6.6%, p=0.0006) and previous glucocorticoid use (80% vs. 36%, p=0.0007) and statin use (50% vs. 22.9%, p=0.037) in the first group. The two groups exhibited no differences in the frequency of positive autoantibodies, except for higher IgG anticardiolipin titers (86 ± 52 vs. 34.5 ± 39 GPL, p=0.003). CONCLUSIONS: Patients with pAPS and TMA have distinct clinical and laboratory spectra from those without TMA, that is characterized by an increased frequency of arterial events, stroke, and higher titers of IgG anticardiolipin; they have deep venous thrombosis less frequently.

Bothrops envenomation and liver hematoma.

OBJECTIVE: To describe a young patient who had a Bothrops envenomation (BE) and evolved with shock and subcapsular liver hematoma. Moreover, a review on BE and liver hematoma was also performed. PATIENTS AND METHODS: A systematic screening of articles was conducted and all articles on the association between BE and liver hematoma were included. A new case report is added to the published list. The following terms were used: "Bothrops" and "liver hematoma" or "liver hemorrhage." RESULTS: This literature search found only one article describing one patient with BE and liver hematoma. We performed our analysis by adding our present case, with a total of 2 cases. Both patients came from Brazil. One of them needed blood transfusions. They both had a good outcome. CONCLUSIONS: We systematically reviewed all published cases of BE and liver hematoma. It is a rare manifestation of ophidism. Physicians should be alert for patients with shock or abdominal pain after BE; they need to perform an ultrasound to exclude liver hematoma.

Sjögren syndrome associated with obsessive-compulsive disorder.

OBJECTIVE: To describe a patient with Sjögren syndrome (SS) associated with obsessive-compulsive disorder (OCD). PATIENTS AND METHODS: Case report and systematic review of the literature. CASE REPORT: A 40-year-old female patient with a history of xerostomia and xerophthalmia initiated in 2015. She also had a history of changing her behavior, and she practices rituals, recurrent obsessions, and compulsions. She was diagnosed with OCD. She was treated with fluoxetine associated with risperidone and then was changed for aripiprazole 10 mg/day. Cognitive-behavioral therapy was also applied. She had good control of the obsessions with these drugs and psychotherapy. Laboratory tests showed positive antinuclear antibodies, anti-Ro/SS-A, and-La/SS-B antibodies. Schirmer test, break up time, and positive green lisamin were all positive. Scintigraphy and ultrasound of salivary glands were positive. A diagnosis of Sjögren syndrome was determined. She was treated with HCQ, vitamin D3 50,000 IU/week, omega-3 2 g, and artificial tears with a good response. Currently, 5 years later, the patient is asymptomatic and has OCD under adequate control even without drugs. CONCLUSIONS: This case illustrates a rare case of a patient with SS who evolved with OCD.

Primary antiphospholipid syndrome: morphofunctional penile abnormalities with normal sperm analysis.

OBJECTIVE: To perform a global gonadal and sexual functions assessment in primary antiphospholipid syndrome (PAPS) patients. METHODS: A cross-sectional study was conducted in 12 male PAPS patients and 20 healthy controls. They were assessed by demographic data, clinical features, systematic urological examination, sexual function, testicular ultrasound, seminal parameters according to the World Health Organization (WHO), seminal sperm antibodies, and hormone profile, including follicle stimulating hormone (FSH), luteinizing hormone (LH), morning total testosterone, and thyroid hormones. RESULTS: The median of current age and age of spermarche were similar in PAPS patients and controls (37.5 vs. 32.4 years, p = 0.270, and 13.1 vs. 12.85 years, p = 0.224, respectively), with a higher frequency of erectile dysfunction in the former group (25% vs. 0%, p = 0.044). Further analysis of PAPS patients with and without previous arterial thrombosis demonstrated that the median penis circumference was significantly lower in PAPS with arterial thrombosis than in PAPS without this complication (8.1 [6-10] vs. 10.2 [10-11] cm, p = 0.007). In addition, the median penis circumference was significantly lower in PAPS patients with erectile dysfunction than in patients without this complication (7.5 [6-9.5] vs. 9.5 [7.5-11] cm, p = 0.039). Regarding seminal analysis, the median sperm concentration, sperm motility, and normal sperm forms by WHO guidelines were comparable in PAPS patients and controls (141.5 [33-575] vs. 120.06 [34.5-329] × 10(6)/ml, p = 0.65; 61.29 [25-80] vs. 65.42 [43-82]%, p = 0.4; 21.12 [10-42.5] vs. 23.95 [10-45]%, p = 0.45, respectively), and none of them had oligo/azoospermia. No differences were observed between PAPS patients and controls regarding the frequency of antisperm antibodies, testicular volume by ultrasound, or hormone profile (FSH, LH, morning total testosterone, and thyroid hormone) (p > 0.05). CONCLUSIONS: Normal testicular function has been identified in PAPS patients, in spite of morphofunctional penile abnormalities. Previous arterial thrombosis may underlie penile anthropometry alteration.

Primary antiphospholipid syndrome in premenopausal women: low vitamin D, high fat mass and maintained bone mineral mass.

The aim of this study was to analyze vitamin D levels and their association with bone mineral density and body composition in primary antiphospholipid syndrome. For this cross-sectional study 23 premenopausal women with primary antiphospholipid syndrome (Sapporo criteria) and 23 age- and race-matched healthy controls were enrolled. Demographic, anthropometric, clinical and laboratorial data were collected using clinical interview and chart review. Serum 25-hydroxyvitamin D levels, parathormone, calcium and 24-hour urinary calcium were evaluated in all subjects. Bone mineral density and body composition were studied by dual X-ray absorptiometry. The mean age of patients and controls was 33 years. Weight (75.61 [20.73] vs. 63.14 [7.34] kg, p = 0.009), body mass index (29.57 [7.17] vs. 25.35 [3.37] kg, p = 0.014) and caloric ingestion (2493 [1005.6] vs. 1990 [384.1] kcal/day, p = 0.03) were higher in PAPS than controls. All PAPS were under oral anticoagulant with INR within therapeutic range. Interestingly, biochemical bone parameters revealed lower levels of 25-hydroxyvitamin D [21.64 (11.26) vs. 28.59 (10.67) mg/dl, p = 0.039], serum calcium [9.04 (0.46) vs. 9.3 (0.46) mg/dl, p = 0.013] and 24-hour urinary calcium [106.55 (83.71) vs. 172.92 (119.05) mg/d, p = 0.027] in patients than in controls. Supporting these findings, parathormone levels were higher in primary antiphospholipid syndrome than in controls [64.82 (37.83) vs. 44.53 (19.62) pg/ml, p = 0.028]. The analysis of osteoporosis risk factors revealed that the two groups were comparable (p > 0.05). Lumbar spine, femoral neck, total femur and whole body bone mineral density were similar in both groups (p > 0.05). Higher fat mass [28.51 (12.93) vs. 20.01 (4.68) kg, p = 0.005] and higher percentage of fat [36.08 (7.37) vs. 31.23 (4.64)%, p = 0.010] were observed in PAPS in comparison with controls; although no difference was seen regarding lean mass. In summary, low vitamin D in primary antiphospholipid syndrome could be secondary to higher weight and fat mass herein observed most likely due to adipocyte sequestration. This weight gain may also justify the maintenance of bone mineral density even with altered biochemical bone parameters.
