Dengue rhabdomyolysis successfully treated with hemoperfusion using CytoSorb® in combination with continuous renal replacement therapy: a case report.

BACKGROUND: Dengue fever is a mosquito-borne viral infection with a broad spectrum of clinical manifestations. Expanded dengue syndrome includes unusual manifestations that do not fall into the categories of dengue fever, dengue hemorrhagic fever, or dengue shock syndrome. Rhabdomyolysis causing acute renal failure in dengue is one such unusual manifestation, the pathophysiology of which is incompletely understood. CASE PRESENTATION: We describe a 21-year-old Sri Lankan man with dengue fever who developed severe rhabdomyolysis and acute kidney injury with extremely high creatinine phosphokinase levels (> 2 million U/L). Management of this patient was challenging as his creatinine phosphokinase kept rising with persistent anuria despite hydration, intermittent hemodialysis, and, later, continuous venovenous hemodiafiltration. Further therapeutic options were explored, and CytoSorb® adsorber was added as an adjunct to continuous venovenous hemodiafiltration, following which we observed a marked reduction in his creatinine phosphokinase and myoglobin levels over the next 12 hours and complete renal recovery over the next 5 weeks. CONCLUSION: We report a rare case of significant rhabdomyolysis secondary to dengue infection leading to acute kidney injury. Continuous venovenous hemodiafiltration performed with the hemofilter Pecopen 140 was ineffective, and the addition of CytoSorb® adsorber as an adjunct therapy to continuous venovenous hemodiafiltration may have a potential benefit in removing high-molecular-weight proteins such as myoglobin.

Mechanical ventilation practices in Asian intensive care units: A multicenter cross-sectional study.

PURPOSE: This study investigated current practices of mechanical ventilation in Asian intensive care units, focusing on tidal volume, plateau pressure, and positive end-expiratory pressure (PEEP). MATERIALS AND METHODS: In this multicenter cross-sectional study, data on mechanical ventilation and clinical outcomes were collected. Predictors of mortality were analyzed by univariate and multivariable logistic regression. A scoring system was generated to predict 28-day mortality. RESULTS: A total of 1408 patients were enrolled. In 138 patients with acute respiratory distress syndrome (ARDS), 65.9% were on a tidal volume ≤ 8 ml/kg predicted body weight (PBW), and 71.3% were on sufficient PEEP. In 1270 patients without ARDS, 88.8% were on a tidal volume ≤ 10 ml/kg PBW. A plateau pressure < 30 cmH2O was measured in 92.2% of patients. Mortality rates increased from 13% to 74% as the generated predictive score increased from 5 to ≥8.5. Income classification, age, SOFA score, PaO2/FiO2 ratio, plateau pressure, number of vasopressors, and steroid use were associated with mortality. CONCLUSIONS: In Asia, low tidal volume ventilation and sufficient PEEP were underused in patients with ARDS. The majority of patients without ARDS were on intermediate tidal volumes. Country income, age, and severity of illness were associated with mortality.

A Rare Case of Paraneoplastic Guillain-Barré Syndrome in a Patient with Endometrial Cancer.

Introduction: Guillain-Barré syndrome is an acute, inflammatory polyradiculoneuropathy of autoimmune aetiology. It is a rare disease seen in 1 in 100,000 person-years. Up to 20% of those affected develop severe disability; mortality in Guillain-Barré syndrome is 5%. Guillain-Barré, associated with many malignancies as a paraneoplastic phenomenon, has been reported - especially in haematological malignancies such as lymphoma and leukaemia. Solid tumours associated with paraneoplastic Guillain-Barré syndrome are breast and lung cancers. The association between paraneoplastic Guillain-Barré syndrome and gynaecological malignancies are rare, and only a handful of cases have been previously reported in gynaecological cancers. Case description: We discuss a 65-year-old Sri Lankan female patient diagnosed with metastatic endometrial carcinoma who presented with paraneoplastic Guillain-Barré syndrome. The patient was treated appropriately and eventually recovered from her condition. Conclusion: Paraneoplastic Guillain-Barré syndrome is a rare phenomenon that clinicians can easily miss, and it has rarely been described in gynaecological cancers. Our patient was diagnosed with this rare phenomenon. The timely recognition and prompt treatment of this potentially life-threatening condition with multiple complications is essential in managing patients with malignancies and neuropathy. Further studies on paraneoplastic Guillain-Barré syndrome are needed as cases may be underreported. LEARNING POINTS: Paraneoplastic Guillain-Barré syndrome e is a very rare phenomenon that can be easily missed by clinicians.Paraneoplastic Guillain-Barré syndrome has rarely been described in gynecological cancers.The timely recognition and prompt treatment of this potentially life-threatening condition with multiple complications is essential in managing patients with malignancies and neuropathy.

Vibrio vulnificus pneumonia with multiorgan failure: a case report and review of the literature.

BACKGROUND: Vibrio vulnificus is a gram-negative bacterium causing three clinical syndromes namely, gastrointestinal symptoms, skin sepsis and primary sepsis. Primary sepsis exhibits mortality rates exceeding 50%, particularly in the immunocompromised. Vibrio vulnificus is transmitted via consumption of contaminated seafood and contaminated seawater skin exposure. We describe a rare case of an immunocompetent male presenting with an atypical Vibrio vulnificus infection, culminating in severe pneumonia requiring intensive care. CASE PRESENTATION: A 46 year old Indian male dockyard worker, a non-smoker and teetotaler, of Indian origin presented to the emergency treatment unit of a tertiary care hospital in Sri Lanka, with fever, productive cough with yellow sputum, pleuritic chest pain and tachypnea for five days. He had no gastrointestinal or skin manifestations. His respiratory rate was 38 breaths/min, pulse rate was 120 bpm, blood pressure was 107/75 mmHg and pulse oximetry was 85% on air. Chest X-ray revealed consolidation of the left lung. Empiric intravenous Piperacillin-tazobactam and Clarithromycin were commenced after obtaining blood and sputum cultures. Over the next 24 h, his oxygen requirement rose and as he required vasopressor support, he was admitted to the intensive care unit. He was intubated and bronchoscopy was performed on day two, which demonstrated thick secretions from left upper bronchial segments. His antibiotics were changed to intravenous ceftriaxone and doxycycline following a positive blood culture report of Vibrio vulnificus. He was ventilated for ten days and his intensive care stay was complicated with a non-oliguric acute kidney injury, with serum creatinine rising up to 8.67 mg/dL (0.81-0.44 mg/dL). He developed mild thrombocytopenia with platelets dropping to 115 × 103 /uL (150-450 × 103/uL) which resolved spontaneously. Vasopressors were weaned off by day eight and the patient was extubated on day ten. He was discharged from intensive care on day twelve and made a full recovery. CONCLUSIONS: Pneumonia itself is an atypical manifestation of Vibrio vulnificus and furthermore, this patient was immunocompetent and did not exhibit the classical gastro-intestinal and skin manifestations. This case highlights the occurrence of atypical Vibrio sp. infections in patients with high exposure risks and the need for early supportive and appropriate antibiotic therapies.

A rare case of acute liver failure with intrahepatic cholestasis due to dengue hemorrhagic fever: CytoSorb® and plasma exchange aided in the recovery: case report.

BACKGROUND: Dengue haemorrhagic fever is a severe form of acute dengue infection characterized by leakage of plasma through capillaries into body spaces resulting in circulatory insufficiency leading to shock. Despite varying degrees of liver involvement occurring in acute dengue infection, intrahepatic cholestasis is very rare in the literature with only two cases reported so far. We report a challenging case of a middle-aged woman with DHF complicated by acute liver failure, coagulopathy, acute renal failure and prolonged intrahepatic cholestasis. She was successfully managed in the intensive care unit with supportive therapy, Cytosorb® and therapeutic plasma exchange. CASE PRESENTATION: A 54-year-old Sri Lankan obese woman with multiple comorbidities presented with fever, headache, vomiting and generalized malaise for 3 days and was diagnosed with dengue haemorrhagic fever. Despite the standard dengue management, she clinically deteriorated due to development of complications such as, acute liver injury, intrahepatic cholestasis and acute renal injury. Acute liver failure was evidenced by transaminitis, lactic acidosis, coagulopathy with pervaginal bleeding and severe encephalopathy necessitating elective intubation and mechanical ventilation. She was immediately transferred to intensive care facilities where she underwent supportive management for liver failure, continuous renal replacement therapy coupled with cytosorb and therapeutic plasma exchange with which she made a remarkable recovery. CONCLUSION: Acute liver failure with a prolonged phase of intrahepatic cholestasis is a very rare complication of acute dengue illness which is sparsely documented in medical literature so far. This patient was managed successfully with supportive therapy, aided by cytoSorb hemo-adsorption and therapeutic plasma exchange.

Clinical manifestations of wasp stings: a case report and a review of literature.

BACKGROUND: Wasp stinging, a neglected tropical entity can have a myriad of local and systemic effects. We present a case of multi-organ injury following multiple wasp stings and a review of literature on the systemic manifestations of wasp stings. CASE PRESENTATION: A 48-year-old Sri Lankan male who suffered multiple wasp stings, developed an anaphylactic shock with respiratory failure, which was treated with adrenaline and mechanical ventilation. Within the next 2 days the patient developed acute fulminant hepatitis, stage III acute kidney injury, rhabdomyolysis, haemolysis and thrombocytopenia. The patient was treated in the intensive care unit with ionopressors and continuous renal replacement therapy (CRRT). Haemoadsorbant therapy was used in adjunct with CRRT. There was a gradual recovery of the organ functions over the 1st week. However, the patient succumbed to fungal sepsis on the 16th day despite treatment. We conducted a literature review to identify the various clinical manifestations of wasp stinging. Wasp venom contains enzymes, amines, peptides and other compounds. These proteins can cause type 1 hypersensitive reactions ranging from local skin irritation to anaphylactic shock. Furthermore, the toxins can cause direct organ injury or delayed hypersensitivity reactions. The commonly affected organs are the kidneys, liver, and muscles. The effect on the haematological system manifests as coagulopathy and/or cytopenia. The heart, nervous system, lungs, intestines and skin can be affected rarely. Treatment is mainly supportive. CONCLUSION: In conclusion, wasp envenomation can result in multi-organ injury and attention should be paid in doing further research and establishing evidence-based treatment practices.

Cytomegalovirus pneumonia in a background of central nervous system tuberculosis.

A 32-year-old patient, who was on treatment for tuberculous meningitis complicated with venous sinus thrombosis, was referred to the medical unit as he developed new onset fever, cough and shortness of breath. He was in respiratory distress and needed intubation. Investigations revealed elevated liver enzymes, leukopenia, spherocytosis and lower lobe predominant consolidations and diffuse nodules in the high-resolution computed tomography. He was suspected to have cytomegalovirus (CMV) pneumonia with the above results, and further investigations revealed an extremely elevated CMV viral load. He was treated with ganciclovir followed by valganciclovir for a total of 42 days resulting in a complete recovery. Liver functions resolved with anti-viral treatment, and he was started on full anti-tuberculosis (TB) treatment. Further investigations did not reveal evidence of immunosuppression. Association of CMV and TB is explained genetically, although clinical association is rarely described. The presence of either infection should lead to higher degree of suspicion of the respective other condition in relevant clinical setting.
