Views: 149HTML: 15 PDF: 126Pleuroperitoneal leak as a cause of pleural effusions in peritoneal dialysis is a rare but important complication to consider in continuous ambulatory peritoneal dialysis (CAPD) patients presenting with recurrent progressive dyspnoea. Generally, these effusions are unilateral and right-sided, resulting in shortness of breath and reduced ultrafiltration volume, which are initially managed by peritoneal rest. We describe a case of bilateral pleural effusions in a 57-year-old female on chronic CAPD who developed recurrent progressive dyspnoea but maintained adequate dialysis output. A chest radiograph revealed bilateral pleural effusions with high glucose content, and scintigraphy confirmed the existence of a definite pleuroperitoneal communication. She was managed by temporary substitution to haemodialysis, followed by suturing of the shunt and successful video-assisted thoracoscopic surgery (VATS) pleurodesis with an aldehyde-based surgical glue. Unexplained recurring dyspnoea in chronic CAPD should raise the suspicion of a possible pleuroperitoneal leak, even in patients without an apparent loss of ultrafiltration. Pleurodesis using an aldehyde-based adhesive was effective and tolerated well by our patient and may be considered in managing cases of recurrent pleural effusion.

Views: 375HTML: 31 PDF: 255Introduction: Combination-based adjuvant chemotherapy utilising capecitabine and oxaliplatin is widely used in gastric cancer treatment. Rare but severe cardiac events such as prolonged QT, cardiac arrest and cardiogenic shock can result from their use.
Case description: A 45-year-old female with gastric adenocarcinoma was started on capecitabine-oxaliplatin chemotherapy one week before presenting to the emergency department with weakness. Blood pressure was 78/56 mmHg, heart rate 140 bpm and oxygen saturation 85%. She became unresponsive with pulseless ventricular fibrillation; CPR was initiated with immediate intubation. She received two shocks with a return of spontaneous circulation. Laboratory tests revealed serum potassium (3.1 mmol/l), magnesium (1.1 mg/dl) and troponin (0.46 ng/ml). An EKG revealed sinus tachycardia with a prolonged QT interval (556 ms). The combined effects of capecitabine, oxaliplatin and electrolyte abnormalities likely contributed to the QT prolongation. An echocardiogram demonstrated an ejection fraction of 10%–15%. An emergent right-heart catheterisation showed right atrial pressure of 10 mmHg and pulmonary artery pressure of 30/18 mmHg; cardiac output and index were not recorded. An intra-aortic balloon pump was placed, and she was admitted to the ICU for cardiogenic shock requiring norepinephrine, vasopressin and dobutamine. A repeat echocardiogram showed a significantly improved ejection fraction of 65%, and she was discharged.
Discussion: Capecitabine and oxaliplatin cardiotoxicity is an exceedingly rare occurrence, with both drugs reported to cause QT prolongation.
Conclusion: Healthcare providers must recognise the QT prolongation effects of capecitabine and oxaliplatin, leading to life-threatening cardiac arrhythmias. -
Views: 245HTML: 17 PDF: 236Introduction: A case of ocular bartonellosis under anti-tumour necrosis factor treatment is described.
Case description: A 29-year-old woman with psoriasis who had been on certolizumab treatment was examined with a left visual deterioration following a fever bout, malaise, and placoid erythematous rashes on her neck. As there was acute anterior uveitis in her left eye, it was recommended to stop certolizumab treatment for a possible infectious aetiology. However, her physician elected to continue the certolizumab treatment. Ten days later, the patient noticed further visual decline despite the topical steroid treatment. This time, there were scattered yellow-white small retinitis foci at the left posterior pole. Infectious agents were searched and while Bartonella henselae antibodies were negative for immunoglobulin M, the immunoglobulin G titre was 1/80. Clinical findings were improved with the systemic treatment of oral trimethoprim-sulfamethoxazole (160/800 mg twice daily for six weeks) and azithromycin (500 mg once daily for two weeks).
Discussion: Though extremely rare, ocular bartonellosis should be kept in mind in patients on anti-tumour necrosis factor treatment as rapid and accurate diagnosis may end up with an excellent visual outcome and full recovery. -
Views: 276HTML: 35 PDF: 314Osmotic demyelination syndrome (ODS) is a disorder characterised by the widespread development of demyelination in both pontine and extrapontine regions. It has been recognised as a complication arising from the rapid correction of hyponatraemia. This study presents the case of a 20-year-old Thai female patient at 10 weeks gestation, exhibiting an initial presentation of catatonia – an uncommon manifestation of ODS. The patient developed symptoms following the rapid correction of hyponatraemia in the context of hyperemesis gravidarum. Magnetic resonance imaging (MRI) of the brain revealed a trident or bat-wing-shaped pattern in T2-weighted and fluid-attenuated inversion recovery (FLAIR) sequences at the central pons. The patient underwent five cycles of plasmapheresis and received rehabilitation, leading to clinical improvement.

Views: 366HTML: 33 PDF: 256Background: This report presents the influence of immunosuppression by new rheumatological therapies on hepatitis E virus infection in a 54-year-old male patient with an anti-synthetase syndrome and treatment with methotrexate and rituximab.
Case description: The patient arrived at the Emergency Department with epigastric pain, vomiting and dark urine. Initial examination revealed signs of inflammation and hepatic dysfunction. Subsequent laboratory tests and imaging confirmed acute hepatitis E infection in the context of recent initiation of rituximab therapy. Despite initial suspicion of pancreatitis, subsequent investigations ruled out pancreatic involvement. Treatment with ribavirin, along with supportive measures, led to significant clinical improvement with resolution of jaundice, ascites, and oedema.
Conclusions: This case underscores the importance of considering hepatitis E in patients with autoimmune conditions, especially when initiating immunosuppressive therapies, a situation that is not well described in scientific literature and is increasingly common, necessitating proper recognition. -
Views: 578HTML: 13 PDF: 350Introduction: During treatment for malignant lymphoma, cytopenia can develop for several reasons. This can range from mild cytopenias leading to infection and bleeding to full-blown drug-induced aplastic anaemia. While aplastic anaemia affects individuals of all genders and ages, here, we describe aplastic anaemia after chemotherapy exposure to bendamustine in a 65-year-old female with non-Hodgkin’s lymphoma.
Case description: A 65-year-old woman with recurrent indolent marginal zone lymphoma and post-chemotherapy with bendamustine and rituximab, presented with a neutropenic fever and was admitted with a leading diagnosis of sepsis. In the previous two weeks, the patient required regular transfusions of packed red blood cells and platelets and maintained a daily ZARXIO® regimen. Laboratory results revealed pancytopenia, and broad-spectrum antibiotics (cefepime/vancomycin) were given. The patient was subsequently admitted to the hospital under the care of the haematology/oncology team and was ultimately diagnosed with aplastic anaemia, likely as a consequence of bendamustine chemoimmunotherapy. She elicited a positive response to the triple immunosuppressive therapy (IST) regimen (two immunotherapeutic agents plus one anti-thymocyte globulin (ATG), after which her cell counts returned to normal.
Conclusions: This case underscores the importance of recognising haematologic complications linked to bendamustine and advocates for further research to increase the understanding among healthcare professionals of drug-induced aplastic anaemia. Bendamustine can cause severe autoimmune haemolytic anaemia and aplastic anaemia and may require multiple transfusions and a multidrug regimen for treatment. The use of ATG as a therapeutic intervention is appropriate because it has been effective in treating aplastic anaemia. -
Views: 360HTML: 17 PDF: 238Anagrelide is a medication primarily used to manage thrombocytosis, an abnormal increase in platelet levels in the blood. It is often prescribed for patients with myeloproliferative disorders, such as essential thrombocythaemia (ET). Given the heightened susceptibility to thromboembolism associated with this condition, the primary emphasis in treatment revolves around reducing the risk of thrombotic events through the administration of cytotoxic agents. While anagrelide is generally effective in reducing platelet counts, it comes with potential side effects, including an increased risk of certain thrombotic events. Anagrelide acts by inhibiting megakaryocyte maturation and platelet release, thereby reducing platelet production. However, this platelet-lowering effect may be accompanied by an increase in platelet activation and reactivity, which could contribute to a prothrombotic state. We present a case of a 60-year-old female with a history of ET, managed with anagrelide and hydroxyurea therapy, who experienced an acute ST-elevation myocardial infarction.

Views: 194HTML: 9 PDF: 189Spontaneous bleeding into the upper airways is a rare and potentially life-threatening complication of chronic anticoagulation. There are scarce cases in the literature demonstrating upper airway haematomas secondary to warfarin use, which is the predominant anticoagulant used by clinicians despite having a complex pharmacokinetic and pharmacodynamic profile. We report a compelling case featuring warfarin-induced sublingual haematoma, managed conservatively through the reversal of anticoagulation using fresh frozen plasma complemented by vigilant monitoring within the Intensive Care Unit (ICU).

Views: 658HTML: 74 PDF: 519Sodium-glucose cotransporter-2 (iSGLT2) inhibitors, which include dapagliflozin, canagliflozin and empagliflozin, are a class of drugs initially used in the oral treatment of diabetes, heart failure and renal failure. They target the reabsorption of glucose in the kidney. Although they bring benefit to patients with these conditions and in general produce few adverse effects, in some cases, iSGLT2 can cause serious adverse effects such as metabolic acidosis, and fungal or bacterial urinary infections. Oncology patients, who in general have a weak immune system and are usually treated with chemotherapy and/or immunotherapy, are more susceptible to this type of adverse events than other patients. For this reason, it is necessary to adequately select the patients eligible to receive this type of drug and evaluate the potential benefits for them. In this series of five cases, we present two cases of metabolic acidosis, two cases of bacterial urinary sepsis, and one case of fungal urinary sepsis that occurred in patients admitted to the Medical Oncology Department of the University Hospital of Salamanca in 2023.

Views: 337HTML: 75 PDF: 236Background: Hydrophilic polymer gel coatings are used on different intravascular devices to prevent vasospasm and thrombosis. However, it may become dislodged from these devices, leading to ischaemic complications in various organs including the skin, kidneys, brain, heart or lungs. Hydrophilic polymer embolisation (HPE) is a rare complication following endovascular procedures that is currently not fully recognised. The current knowledge of this phenomenon is based on reports consisting of histologic evidence of foreign polymers in the affected organ.
Case description: A 76-year-old male with a history of hypertension, type 2 diabetes, renal cell carcinoma and chronic kidney disease underwent endovascular stenting of the superficial femoral artery due to critical limb ischaemia of the right foot. The patient had an acute kidney injury following the procedure. Upon examining the legs, there were tender non-blanching macular lesions on the right lower limb. A skin biopsy of the lesion was performed and showed hydrophilic polymer embolisation. Unfortunately, a few weeks later the patient was readmitted due to a worsening of the right foot wound situation, which required below-knee amputation.
Conclusion: HPE is a rarely reported complication after endovascular interventions, with the potential to embolise to multiple organs. By observing skin manifestations, it is possible to aid the early detection of ischaemic events in other organs and identify their underlying causes. Generally speaking, the course is benign and self-limiting when the skin is involved, but may be more sinister especially when other organs (e.g. brain) are involved.
