Combination immunotherapy of nivolumab plus ipilimumab in a lung cancer patient with Werner syndrome; a case report.

Werner syndrome (WS) is a rare progressive disorder that is characterized by premature aging of all organs. Malignancy is a frequent complication of WS, however, lung cancer patients with WS are much rare. In patients with WS, the treatment for malignancy is often limited due to other complications of severe skin ulcer, diabetes mellitus and cardiovascular disease. Currently, immune-checkpoint inhibitors (ICIs) are standard therapy for several cancer patients and the combination of nivolumab plus ipilimumab has also been approved for the treatment of non-small cell lung cancer (NSCLC). Recent studies have also reported that serious immune-related adverse events (irAEs) induced by ICIs may correlate with elderly or more vulnerable patients. However, the efficacy and safety of ICIs in NSCLC patients with WS remain unclear. To the best of our knowledge, this is the first case describing a NSCLC patient with WS receiving the combination immunotherapy of nivolumab and ipilimumab. Our case showed objective response to ICIs, however, several immune-related adverse events (irAEs) including hypothyroidism, adrenal insufficiency, hard rash and interstitial lung disease occurred, thus resulted in early treatment discontinuation. Our case suggests that immunotherapy for NSCLC patients with WS could be effective, but physicians may be aware of the possibility of multiple irAEs undergoing immunotherapy for NSCLC patients with WS.

Complete Genome Sequencing of Mycobacterium heckeshornense Strain JMUB5695, Isolated from Necrotizing Granulomatous Lesions.

We report the complete genome sequence of Mycobacterium heckeshornense strain JMUB5695, which was isolated from necrotizing granulomatous lesions in a lung cancer patient. The complete genome consists of a 4,865,109-bp chromosome with a GC content of 65.9% and contains no plasmids.

A 63-Year-Old Woman With Progressive Dyspnea After Remission of Lymphoma.

CASE PRESENTAION: A 63-year-old woman visited our hospital for a further evaluation of progressive dyspnea. She had developed a progressive airflow obstruction after 3 years' remission of non-Hodgkin's lymphoma (follicular mixed cell type), which had been treated with chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). The patient's primary care physician had diagnosed her as having COPD and bronchial asthma and had treated her with medications including inhaled corticosteroids, tiotropium, and oral erythromycin. Her dyspnea had gradually worsened, however, and she had a score of 4 on the modified Medical Research Council dyspnea scale at the time of admission to our hospital.

[A case of pulmonary tuberculosis with diminished lung function whose paradoxical reaction led to death].

Paradoxical reaction in tuberculosis treatment is not generally fatal. On rare occasion it can lead a patient with diminished lung function and poor general condition to death. A 60-year-old man with history of left upper lobe resection from tuberculosis was referred to our hospital due to the recurrence of tuberculosis. Sputum examination showed a positive smear with a Gaffky score of 10, and the chest X-ray and CT revealed pulmonary infiltrate with many cavities (bII2) on the whole left lung field. Anti-tuberculosis drugs (isoniazid, rifampicin, ethambutol and pyrazinamide) were administered, but his high fever persisted, and the infiltrate on the chest X-ray deteriorated. While the positive sputum smear persisted, the culture became negative after one month. The tuberculous bacilli were susceptible to all anti-tuberculosis drugs in vitro. Though we performed examinations and trial treatments for non-tuberculous conditions such as pneumonia and drug-induced pneumonia, the patient died after 6 months. A necropsy specimen taken from the worsening lesion (the right upper lobe) as shown on the chest X-ray revealed many epithelioid granulomas. The patient had malnutrition, diabetes, alcoholic hepatic disorder, and insanity. It is supposed that although antituberculosis drugs were effective, a large quantity of killed organisms was continuously excreted from many cavities in the left lung toward the right lung. Lesions in the right lung thus newly produced in this paradoxical reaction seemed to reduce the remaining lung function. In addition, poorly controlled diabetes caused deteriorated heart function. These multiple factors contributed to the poor prognosis of the patient and his ultimate death.

[Clinical review of 8 patients with tuberculous peritonitis].

OBJECTIVE: With the progress of anti-tuberculous therapy, tuberculous peritonitis (TBP) has become a rare manifestation of active tuberculosis. Its early diagnosis is difficult due to lack of pathognomonic findings and specific symptoms. However, early diagnosis is important for effective treatment and for reducing fatality. MATERIALS AND METHOD: We retrospectively reviewed medical records of eight patients who were hospitalized with TBP in National Hospital Organization Omuta National Hospital during the periods between 2001 and 2009. RESULTS: Three patients were males and five were females. The age of the patients ranged between 28 and 80 years old (average 67.3 years). The most common presenting findings were abdominal distention seen in four patients and loss of appetite in five patients. Blood examination suggested that most patients were in poor nutrition. Three patients were diagnosed based on bacteriological examination, two based on histopathological findings of caseating granulomas, two based on the elevation of adenosine deaminase activity in ascitic fluid and one based on clinical diagnosis. The most common CT findings were thin lines along mesenteric vessels representing thickened mesenteric leaves and smooth uniform peritoneal thickening. Most patients were treated with isoniazid, rifampicin and ethambutol for 9 months with/without pyrazinamide initially. Seven patients completed anti-tuberculous therapy successfully and were cured. However, one patient died of the deterioration of tuberculosis. CONCLUSION: TBP should be considered for diagnosis, in patients with non-specific abdominal symptoms. Adenosine deaminase activity in ascitic fluid and CT images are considered to be useful for the diagnosis of TBP in patients in whom bacteriological and histopathological examinations are difficult to perform.

[Case of angioimmunoblastic T-cell lymphoma with eosinophilia and interstitial shadows].

A 76-year-old woman was admitted because of respiratory failure with bilateral multiple interstitial shadows and mediastinal adenopathy on chest CT images. Blood examination revealed eosinophilia without leukocytosis and elevated C-reactive protein levels. Corticosteroids were administered before diagnosis because of rapid respiratory failure. Although her symptoms and pulmonary lesions disappeared with steroid therapy, they recurred 4 days later. A definitive diagnosis was not obtained until bronchofiberoptic examination. At the time of recurrence 6 months later, angioimmunoblastic T-cell lymphoma (AITL) was diagnosed with axillary lymph node biopsy. AITL is rare, and shows rapid deterioration of respiratory failure with poor prognosis. Lymph node biopsy is necessary to establish a definitive diagnosis.
