Deposition of pentamidine analogues in the human body - spectroscopic and computational approaches.

Eur J Pharm Sci 2021 Jun 2;161:105779. Epub 2021 Mar 2.

Department of Organic Chemistry, Faculty of Pharmacy, Medical University of Warsaw, Banacha 1, 02-097 Warsaw, Poland. Electronic address:

Bis-benzamidines are a diverse group of compounds with high potential in pharmacotherapy, and among them, pentamidine is a drug of great therapeutic significance in Pneumocystis jiroveci pneumonia (PJP) prophylaxis and therapy. Pharmacokinetic properties of these cationic species such as transport, acid/base equilibria, and interactions with potential target molecules are still of interest, especially for recently designed compounds. To broaden our knowledge drug-likeness, human serum albumin binding, and acidity constants (K) were experimentally and theoretically examined for five pentamidine analogues 1 - 5 with -NH-CO-chain-CO-NH-bridges of increasing length and O, N, and S atoms in the chain.

MANAGEMENT OF ENDOCRINE DISEASE: Cardiovascular risk assessment, thromboembolism, and infection prevention in Cushing's syndrome: a practical approach.

Eur J Endocrinol 2021 Apr 22;184(5):R207-R224. Epub 2021 Apr 22.

Departments of Medicine (Endocrinology, Diabetes and Clinical Nutrition) and Neurological Surgery, and Pituitary Center, Oregon Health & Science University, Portland, Oregon, USA.

Cushing's syndrome (CS) is associated with increased mortality that is driven by cardiovascular, thromboembolic, and infection complications. Although these events are expected to decrease during disease remission, incidence often transiently increases postoperatively and is not completely normalized in the long-term. It is important to diagnose and treat cardiovascular, thromboembolic, and infection complications concomitantly with CS treatment. Read More

Pneumocystis jiroveci pneumonia, Nocardia brasiliensis, and Mycobacterium tuberculosis co-infection in a myasthenia gravis patient: A case report.

Medicine (Baltimore) 2021 Jan;100(1):e24245

Department of Laboratory Medicine, The First Affiliated Hospital of Zhejiang Chinese Medical University, Hangzhou, China.

Rationale: Myasthenia gravis (MG) is an autoimmune disorder of the neuromuscular junctions that leads to fluctuating weakness and disabling fatigability. Due to difficulty in breathing caused by weakness of the respiratory muscles, patients with MG are more susceptible to pneumonia and other respiratory infections. As many patients with MG are given immunosuppressive therapy, this makes them more prone to infections. Read More

Clinical features and treatment outcomes of human immunodeficiency virus-associated cryptococcal meningitis: a 2-year retrospective analysis.

Chin Med J (Engl) 2020 Dec;133(23):2787-2795

Department of Infection and Immunity, Shanghai Public Health Clinical Center, Fudan University, Shanghai 201508, China.

Background: Cryptococcal meningitis (CM) is one of the most common opportunistic infections caused by Cryptococcus neoformans in human immunodeficiency virus (HIV)-infected patients, and is complicated with significant morbidity and mortality.

A Tale of 2 Pneumos: The Impact of Human Immunodeficiency Virus Exposure or Infection Status on Pediatric Nasopharyngeal Carriage of Streptococcus pneumoniae and Pneumocystis jiroveci: A Nested Case Control Analysis From the Pneumonia Etiology Research In Child Health Study.

Clin Infect Dis 2021 03;72(6):1033-1041

Department of Medicine, Boston University Medical Center, Boston, Massachusetts, USA.

Background: The majority of pediatric human immunodeficiency virus (HIV) cases in Africa reflect maternal-to-child transmission. HIV exposed but uninfected (HEU) children have increased rates of morbidity and mortality when compared to HIV unexposed and uninfected (HUU) children. The mechanisms behind these unexpected trends are only partially understood but could be explained by the differences in the immune response to infections triggered by an altered immune system state.

Sulfonamide desensitization in solid organ transplant recipients: A protocol-driven approach during the index transplant hospitalization.

Transpl Infect Dis 2019 Dec 15;21(6):e13191. Epub 2019 Nov 15.

Division of Infectious Diseases, Oregon Health & Science University, Portland, OR, USA.

Trimethoprim-sulfamethoxazole (TMP-SMX) is the first-line agent for Pneumocystis jiroveci pneumonia (PJP) prophylaxis for solid organ transplant (SOT) recipients because of its efficacy for this indication, extended antimicrobial coverage, and favorable cost. Reported sulfonamide allergy is not uncommon and often results in TMP-SMX avoidance. Desensitization offers an efficacious and cost-effective alternative to TMP-SMX avoidance. Read More

Department of Rheumatology and Immunology.

Systemic lupus erythematosus (SLE) complicated with Pneumocystis jiroveci pneumonia (PCP) is a clinical complex with unsatisfying treatment efficacy and poor prognosis which is difficult to be diagnosed at early stage. The present study aimed to investigate the clinical features of SLE with PCP, recognize the early onset indicating factors, and evaluate the treatment efficacy of combined caspofungin and trimethoprim/sulfamethoxazole (coSMZ).We reviewed data of 9 patients admitted with SLE-PCP and treated with caspofungin combined with coSMZ at Tangshan Gongren Hospital from January 2013 to December 2017.

Infectious Disease Division, NYU Winthrop Hospital, Mineola, New York, United States.

Clinical correlation is essential in assessing the relevance of the patient's history and physical findings in making a clinical presumptive diagnosis. False diagnostic associations may result in misdiagnosis. We present a case of an elderly female with HIV on HAART who presented with shortness of breath assumed to have Pneumocystis (carinii) jiroveci pneumonia (PCP) even though she had a clinical diagnosis of influenza B.

Clinical Performance of (1,3) Beta-D Glucan for the Diagnosis of Pneumocystis Pneumonia (PCP) in Cancer Patients Tested With PCP Polymerase Chain Reaction.

Clin Infect Dis 2019 09;69(8):1303-1309

Infectious Diseases Service, Department of Medicine, Memorial Sloan Kettering Cancer Center, New York, New York.

Background: Serum (1,3)-beta-D glucan (BDG) is increasingly used to guide the management of suspected Pneumocystis pneumonia (PCP). BDG lacks specificity for PCP, and its clinical performance in high-risk cancer patients has not been fully assessed. Polymerase chain reaction (PCR) for PCP detection is highly sensitive, but cannot differentiate between colonization and infection. Read More

1 Division of Pulmonary and Critical Care Medicine, Eastern Virginia Medical School, Norfolk, VA, USA.

Although Pneumocystis jiroveci pneumonia (PCP) is a frequent manifestation of acquired immune deficiency syndrome (AIDS), the granulomatous form is uncommon. Here, we present an unusual case of granulomatous PCP consequent to immune reconstitution inflammatory syndrome (IRIS) after highly active antiretroviral therapy. A 36-year-old woman with human immunodeficiency virus (HIV) presented with cough and dyspnea that were attributed to typical PCP associated with AIDS. Read More

Pneumocystis Jiroveci Pneumonia and Newly Diagnosed Human Immunodeficiency Virus (AIDS) in a 63-Year-Old Woman.

Am J Case Rep 2018 Aug 8;19:927-931. Epub 2018 Aug 8.

Faculty of Medicine, University of Jordan, Amman, Jordan.

BACKGROUND Pneumocystis jiroveci pneumonia (PCP) - formerly known as Pneumocyctis carinii pneumonia - with newly diagnosed AIDS is an uncommon presentation in people over 50 years of age. A high level of suspicion is required for this diagnosis when an elderly patient with pneumonia is not responding to broad-spectrum antibiotic treatment. CASE REPORT We describe the case of a 63-year-old woman who presented with dyspnea, cough, and significant hypoxemia requiring high-flow oxygen supplement with bilateral lung infiltrates, treated with broad-spectrum antibiotics for a presumed diagnosis of pneumonia.

Determining the Incidence of Pneumocystis Pneumonia in Patients With Autoimmune Blistering Diseases Not Receiving Routine Prophylaxis.

JAMA Dermatol 2017 11;153(11):1137-1141

Center for Blistering Diseases, Department of Dermatology, University Medical Center Groningen, University of Groningen, Groningen, the Netherlands.

Importance: Pneumocystis pneumonia (PCP) is a potentially lethal opportunistic infection that primary prophylaxis can help prevent. The risk of prophylactic therapy must be weighed against the incidence of PCP in the patient population. Prophylaxis most frequently involves trimethoprim-sulfamethoxazole, with second-line therapies, including atovaquone, dapsone, and pentamide. Read More
