- Inclusion Body Myositis Treated with AlemtuzumabPublication . Sá, J.; Costelha, J.; Marinho, Antónionclusion body myositis (IBM) is a chronic inflammatory myopathy with a progressive course. It is more common in the later years of life and usually presents with limb weakness. We present the case of a patient who developed proximal weakness in the lower limbs and, four years later, facial asymmetry. Blood analysis revealed high lactate dehydrogenase and creatinine kinase values. The diagnosis was obtained through muscle biopsy which met the histological criteria for IBM. The patient started treatment with alemtuzumab, leading to stabilisation of the symptoms in two years. Learning points: IBM should be considered in the differential diagnosis of muscle weakness.Patients may present uncommon symptoms, such as prominent facial involvement.Alemtuzumab may potentially be beneficial in limiting the progression of IBM.
- Not All ENT Granulomas Are Wegener’s – Keep Tuberculosis in MindPublication . Pedro, Bárbara; Meleiro, Marta; Marinho, AntónioMycobacterium tuberculosis affects the middle ear in rare cases and is a challenging diagnosis. In this case, we present a 57-year-old patient diagnosed with anti-neutrophil cytoplasmic antibody (ANCA)-negative granulomatosis with polyangiitis (GPA) following a biopsy result of nasal granulomas, who was immediately started on immunosuppressive treatment. Years later, she developed progressive hypoacusis. Magnetic resonance imaging (MRI) revealed an extensive mass in the tympanic cavity extending to the mastoid. A biopsy of the mass was positive for Mycobacterium tuberculosis. Immunosuppressants were weaned and the patient was started on anti-tuberculous therapy with resolution of the complaints and findings. Tuberculous infections are difficult to diagnose and frequently mimic other illnesses, but in our case, we believe that an indolent tuberculous process was present from the beginning and evolved under immunosuppressive therapy. Learning points: The differential diagnosis of rhinosinus granulomatous findings includes inflammatory and infectious diseases (for example, tuberculous infections), in addition to neoplasms, cocaine abuse and trauma. A comprehensive differential diagnosis list is essential to mitigate diagnostic errors, especially in patients where auto-immune studies are negative or there is any doubt in the diagnosis. Latent tuberculosis screening should be a concern for physicians treating patients with immunosuppressive therapy, especially in endemic countries.
- Secukinumab on Refractory Lupus NephritisPublication . Costa, Rita; Antunes, Paula; Salvador, Pedro; Oliveira, Pedro; Marinho, AntónioLupus nephritis (LN) is the most frequent severe organ manifestation of systemic lupus erythematosus (SLE). About 30% of patients are refractory to treatment. The authors report a case of treatment of LN with interleukin-17-targeted therapy, demonstrating its possible benefit, after reports of T helper 17 cell involvement in SLE pathogenesis. We present the case of a childbearing age woman with SLE, who developed refractory LN despite all the indicated therapeutic options. During follow up, infection with human papillomavirus was detected, a possible trigger, and the following management was based on this discovery. We currently know that cytokines play a major role in tissue damage and interleukin-17 (IL-17) seems to be a fundamental key in SLE and LN, having shown its expression in renal glomeruli and urinary sediment. Thus, it was decided to start treatment with an anti-IL-17A antibody, secukinumab. After starting secukinumab, clinical and biological features improved and complete renal response was achieved.
- Behçet's Disease and Pregnancy: A Retrospective Case-control StudyPublication . Barros, Tânia; Braga, António; Marinho, António; Braga, JorgeBackground: Behçet's disease (BD) is a rare chronic multisystemic vasculitis of unknown etiology. It is usually diagnosed between the 2nd and 4th decades of life, so its association with pregnancy is not unusual. This study aims to characterize the evolution of pregnancy in a group of pregnant women with BD and the impact of this pathology in embryo-fetal morbidity. Methods: A retrospective case-control study included 49 pregnancies in women suffering from BD, followed in our institution. Pregnancy outcomes were compared with a control group of healthy pregnant women. Two controls per case were randomly selected. Statistical analysis used SPSS 25.0, and a p-value of 0.05 was considered statistically significant. Results: Forty-nine pregnancies were included in 27 patients with BD. BD exacerbation occurred in 32.6% of the pregnancies. There were no significant statistical differences between the two groups regarding the rate of preterm delivery, gestational diabetes, and preeclampsia (p>0.05). In the BD group, we found a higher rate of miscarriage (24.5%) and fetal growth restriction (FGR, 13.3%, p<0.05). In the study group, 13 (32.5%) of the pregnant patients did not need treatment. The cesarean rate was significantly higher in the BD group (43.2% vs 20.4% in the control group, p<0.05), and there were no significant differences in median gestational age at the time of delivery (p>0.05). The birth weight of newborns did not differ significantly between the groups. There was no association of BD with maternal morbidity and neonatal complications. Conclusion: In this study, the majority of pregnant with BD did not present clinical exacerbation of their pathology. However, BD may have an adverse influence on pregnancy outcomes. FGR and miscarriage rates were significantly higher in the study group.
