Azole-resistant Candida albicans Spondylodiscitis After Bariatric Surgery: A Case Report

CASE

We present a case of azole and partial caspofungin-resistant Candida albicans spondylodiscitis, after bariatric surgery with bowel perforation. Treatment included debridement and several months of anidulafungin, complemented with antibacterial therapy because of relapse for bacterial superinfection. After treatment, the infection did not recur clinically or radiologically during one and half years follow-up.

CONCLUSION

Although C. albicans spondylodiscitis is rare, fungi should be suspected as a causative agent. Adequate history, imaging and laboratory testing, and medical and surgical treatment should be performed to successfully eradicate the infection and resolve potential neurological deficits.

Pulmonary mucormycosis: A case report

Mucormycosis is a rare fungal infection caused by Mucorales order fungi. The rhino-cerebral form of mucormycosis is most commonly seen in patients with diabetes mellitus, whereas, pulmonary mucormycosis is a rare manifestation in patients with haematological malignancy and transplant recipients. We report a case of pulmonary mucormycosis presenting with a late acute onset diabetes on a patient immunosuppressed with a low dose of steroids.

We aim to illustrate the need for a high clinical suspicion for the diagnosis of mucormycosis and to report the importance of early and aggressive inhiation of antifungal therapy.

Asymptomatic reactivation of hepatitis B virus after prolonged treatment with etanercept

Etanercept is an anti-tumor necrosis factor ɑ (anti-TNFɑ) drug used for treating immunomediated inflammatory diseases. It is least associated with hepatitis B virus (HBV) reactivation. We present a 71-year-old man with psoriasis refractory to phototherapy and acitretin, which led to etanercept monotherapy. Before anti-TNFɑ treatment, past contact with HBV was elicited; antibodies to HBc and HBs were positive whereas HBsAg was negative. Seven years after treatment initiation, while the patient was completely asymptomatic, a transaminase elevation was found and a reactivation of HBV was documented, with a high viral load of the virus. He started entecavir therapy and, after a 14-month follow-up, the viral load is still detectable at a low level, as well as HBsAg. We emphasize the late and asymptomatic reactivation of HBV associated with soluble anti-TNFɑ monotherapy. This case reinforces the importance of current recommendations for periodic monitoring of viral load and HBV markers in all patients that have had prior contact with HBV (positive anti-HBc), with or without indication for treatment of HBV (HBsAg and HBV-DNA negative).

[Uveitis]

Uveitis is a general term that refers to the inflammation of uveal tract, which is an important cause of blindness in young people. It is well known that uveitis can be the initial manifestation of a systemic disease (S.D.), and may appear years before the diagnosis of the primary disease. Uveitis should be integrated in a systemic study with proper testing. Therefore, the diagnosis is a matter for the ophthalmologist and the Specialist in internal medicine. We have made a retrospective study of 71 patients with chronic uveitis or panuveitis. We found 54.9% of primary uveitis and 45.1% of S.D. associated uveitis, most of them with Behçet's disease (16/71) and Ankylosing Spondilytis (7/71). HLA typing of the patients showed a decreased frequency of HLA A1 and HLA A3 antigens and an increased frequency of the HLA B27 antigen, when compared to a Portuguese control population. We confirmed the important role of HLA B27 as an independent susceptibility factor for anterior uveitis. The lowest HLA A3 frequency was observed in the group of S.D. associated uveitis, which could suggest that this antigen may play a role as a factor of resistance to uveitis.

[Idiopathic pulmonary hemosiderosis]

We report a case of a 23 year-old man admitted to hospital with cough, fever and recurrent episodes of haemoptysis. Laboratory findings, which included a pulmonary biopsy, established the diagnosis of Idiophatic Pulmonary Hemosiderosis (IPH). Despite a number of morphologic, immunologic and ultrastructural studies, the etiology and pathogenesis of this disease remain indetermined. To diagnose an IPH all the other causes of pulmonary hemorrhage must be excluded. This is a rare disease, even more rare in adults. Based on these facts the authors publish this article, which includes the case report and a literature review.
