[Disseminated aspergillosis in a patient with simultaneous pancreas and kidney transplant]. / Diseminirana aspergiloza u bolesnice s transplantiranim bubregom i gusteracom.

A 31-year-old woman suffering from diabetes type1 and terminal kidney disease, with simultaneously transplanted kidney and pancreas, developed an episode of acute organ rejection caused by antibodies. The management of organ rejection was complicated by cytomegalovirus viremia, with accompanying leukopenia and neutropenia. The patient also developed invasive aspergillosis of the lungs, which progressed and disseminated hematogenously to the thyroid gland and the skin. Due to resistance to classical antimycotic therapy, the patient was treated with a combination of caspofungin and variconazole. In the beginning of treatment, the effects of this combined therapy were not evident due to strong immunosuppression caused by antimycotic immunoglobulin, which the patient had been administered on her previous hospital stay to treat acute kidney transplant rejection caused by antibodies, as well as due to immunosuppression caused by tacrolimus, mycophenolate mofetil and prednisone. On combined therapy with antimycotic drugs and supportive therapy, the patient was completely cured.

Polyomavirus associated nephropathy after kidney and pancreas transplantation: case report.

Polyomavirus virus associated nephropathy (PVAN) is an important cause of graft failure in the renal transplant population. The prevalence of PVAN has increased from 1% to 10% in the past decade, leading to loss of transplanted organ in 30% to 80% of cases. In the absence of specific antiviral drugs, early detection of disease and modification/reduction of immunosuppressive regimen is currently the cornerstone of therapy. In the setting of multiorgan transplantation, like simultaneous pancreas and kidney transplantation (SPKT), diagnosis and therapy of PVAN can be even more challenging problem. We report a first described case of PVAN in patient after SPKT in Croatia. Patient is a 32 years old Caucasian male with type 1 diabetes mellitus and end stage renal failure, diagnosed for PVAN 6 month after SPKT. Patient was treated with reduced immunosuppressive regimen. At 32 month follow up, patient has preserved kidney and pancreas function with estimated glomerular filtration (eGFR) rate of 91 mL/min and no signs of PVAN on his 2 year protocol kidney biopsy.

First documented case of BK nephropathy in kidney transplant recipient in Croatia: usage of urine cytology in evaluation process.

BK virus associated nephropathy (BKVAN) in transplanted kidney, although recognized as a distinct entity in the 1970-es, continues to represent a challenge in kidney transplantation, mainly because the optimal treatment approach has not been determined yet. The fact that about 10-20% of patients have simultaneously some stage of acute rejection, complicate the treatment even more. Herein we present a case of BK nephropathy in the patient, one year after combined liver and kidney transplantation, complicated by episode of acute T-cell mediated rejection. Identification of decoy cells by cytology urine exam in patient with acute kidney graft function deterioration, raised suspicion of BKVAN. Diagnosis has been made by histological examination and confirmed with immunohistochemical staining for BK virus in kidney graft biopsy. One month after he had been treated for BKVAN with intravenous immunoglobulin, leflunomide and overall immunosuppression therapy reduction, there was further deterioration of graft function due to an episode of acute T-cell mediated rejection (Banff classification IA). He received 500 mg of metilprednisolon intravenously and mycophenolate mofetil had been reintroduced, which resulted in slow partial recovery of the graft function, but never to the baseline values. For the past two years his renal graft function has been stable, maintaining lower levels of immunosuppressive therapy. According to our knowledge this is the first documented case of BK virus associated nephropathy, diagnosed and confirmed with immunohistochemical staining of tissue from kidney biopsy in Croatia.

Stevens-Johnson syndrome as an unusual adverse effect of azithromycin.

Stevens-Johnson syndrome mostly involves the skin and mucous membranes. The diagnosis is made when the characteristic rash appears 1 to 3 weeks after exposure to a known stimulus and cannot be explained by some other diagnosis. A 62-year-old woman was admitted for evaluation of toxo-allergic dermatitis and collagenosis. Ten days prior to admission she was taking a course of azithromycin for upper respiratory tract infection. After a few days she was feeling better but maculopapular, erythematous rash developed over her palms, accompanied by fever and chills as well as reddish discoloration around her eyes. Within the next few days the rash progressed to the feet. Routine hematologic, biochemical and immunologic studies did not confirm the diagnosis of inflammatory rheumatic disease. Corticosteroid therapy with methylprednisolone (1 mg/kg) for the presumed Stevens-Johnson syndrome was started and her condition improved in several days; she became afebrile and her skin lesions gradually disappeared. There is only one report, in a child, documenting the association of Stevens-Johnson syndrome with azithromycin, as in this patient.

Takayasu's arteritis and chronic autoimmune thyroiditis in a patient with type 1 diabetes mellitus.

Takayasu's arteritis is a rare, chronic inflammatory disease of unknown origin, affecting the walls of the aorta and its main branches, as well as coronary and pulmonary arteries. The inflammation of the arteries may lead to stenosis, occlusions, dilatations, and aneurysms of involved vessels. It is relatively common in Asia and the Far East but is rare in the Western Hemisphere. We present the case of a 36-year-old white woman with a history of type 1 diabetes mellitus and chronic autoimmune thyroiditis who complained of easy fatigability in the upper limbs, with absent arterial pulses in the upper limbs and audible bruits over both subclavian and left common carotid arteries. Intra-arterial digital subtraction angiography revealed complete or subtotal obliteration of the aortic arch's branches, with the brain supplied with blood only by the left vertebral artery originating directly from the aortic arch. We diagnosed Takayasu's arteritis with abnormal origin of the left vertebral artery. To the best of our knowledge, our case of Takayasu's arteritis and chronic autoimmune thyroiditis in a type 1 diabetic patient with abnormal origin of the left vertebral artery is the first one ever described.
