Epidemiologic characteristics and clinical features of patients with monkeypox virus infection from a hospital in Peru between July and September 2022.

OBJECTIVES: Monkeypox (Mpox) recent outbreak has changed in terms of predominant transmission route and typical presentation. Describing current epidemiological and clinical characteristics is crucial to identifying cases and halting transmission. METHODS: An observational study was conducted at a Peruvian tertiary-level hospital and included all individuals with Mpox virus infection between July 01 and September 03, 2022. RESULTS: Among 205 confirmed cases, 99% (202/205) were men, 94% (192/205) were men who have sex with men or bisexual, and 66% (136/205) were living with HIV. Regarding sexual behavior, 87% (179/205) had a sexual encounter 21 days before consultation, although only 8% (17/205) identified sexual contact with a Mpox confirmed case; 65% (133/205) had sexual intercourse with casual partners, 55% (112/205) reported a last sexual partner unknown, and 21.5% (44/205) continued having sexual intercourse with symptoms. Systemic symptoms were fever (162/205, 79%), malaise (123/205, 60%), headache (119/205, 58%), fatigue (105/205, 52%), and lymphadenopathy (111/205, 54%). The distribution of skin lesions was generalized (166/205, 81%), located in the anogenital area (160/205, 78%), polymorphic (174/205, 85%), and it was the first symptom identified in 46% (94/205) of cases. Overall, 10% (21/205) required hospitalization, of whom 85.7% (18/205) have HIV infection. Complications included bacterial superinfection (n = 18), proctitis (n = 6), balanitis (n = 4), and necrosis of skin lesions (n = 3). CONCLUSION: In 2022, Mpox mainly affects men who have sex with men and People living with HIV/AIDS. It presents with skin lesions localized to the anogenital area and can lead to severe complications requiring hospitalization.

Mpox in people with advanced HIV infection: a global case series.

BACKGROUND: People living with HIV have accounted for 38-50% of those affected in the 2022 multicountry mpox outbreak. Most reported cases were in people who had high CD4 cell counts and similar outcomes to those without HIV. Emerging data suggest worse clinical outcomes and higher mortality in people with more advanced HIV. We describe the clinical characteristics and outcomes of mpox in a cohort of people with HIV and low CD4 cell counts (CD4 <350 cells per mm3). METHODS: A network of clinicians from 19 countries provided data of confirmed mpox cases between May 11, 2022, and Jan 18, 2023, in people with HIV infection. Contributing centres completed deidentified structured case report sheets to include variables of interest relevant to people living with HIV and to capture more severe outcomes. We restricted this series to include only adults older than 18 years living with HIV and with a CD4 cell count of less than 350 cells per mm3 or, in settings where a CD4 count was not always routinely available, an HIV infection clinically classified as US Centers for Disease Control and Prevention stage C. We describe their clinical presentation, complications, and causes of death. Analyses were descriptive. FINDINGS: We included data of 382 cases: 367 cisgender men, four cisgender women, and ten transgender women. The median age of individuals included was 35 (IQR 30-43) years. At mpox diagnosis, 349 (91%) individuals were known to be living with HIV; 228 (65%) of 349 adherent to antiretroviral therapy (ART); 32 (8%) of 382 had a concurrent opportunistic illness. The median CD4 cell count was 211 (IQR 117-291) cells per mm3, with 85 (22%) individuals with CD4 cell counts of less than 100 cells per mm3 and 94 (25%) with 100-200 cells per mm3. Overall, 193 (51%) of 382 had undetectable viral load. Severe complications were more common in people with a CD4 cell count of less than 100 cells per mm3 than in those with more than 300 cells per mm3, including necrotising skin lesions (54% vs 7%), lung involvement (29% vs 0%) occasionally with nodules, and secondary infections and sepsis (44% vs 9%). Overall, 107 (28%) of 382 were hospitalised, of whom 27 (25%) died. All deaths occurred in people with CD4 counts of less than 200 cells per mm3. Among people with CD4 counts of less than 200 cells per mm3, more deaths occurred in those with high HIV viral load. An immune reconstitution inflammatory syndrome to mpox was suspected in 21 (25%) of 85 people initiated or re-initiated on ART, of whom 12 (57%) of 21 died. 62 (16%) of 382 received tecovirimat and seven (2%) received cidofovir or brincidofovir. Three individuals had laboratory confirmation of tecovirimat resistance. INTERPRETATION: A severe necrotising form of mpox in the context of advanced immunosuppression appears to behave like an AIDS-defining condition, with a high prevalence of fulminant dermatological and systemic manifestations and death. FUNDING: None.

Insuficiencia respiratoria y hemoptisis en paciente con dengue: Hemorragia alveolar difusa como presentación inusual de dengue grave / Respiratory insufficiency and hemoptysis in a patient with dengue: Diffuse alveolar hemorrhage as an unusual presentation of severe dengue

Introducción: La infección por el virus del dengue es una enfermedad endémica en ciertas regiones del Perú. La mayoría de estos casos se clasifican como dengue sin signos de alarma y la mortalidad reportada es menor de 1%. Sin embargo, existen ciertas condiciones asociadas a la enfermedad que podrían incrementar la mortalidad. Reporte de caso: Se presenta el caso de una paciente mujer de 48 años procedente de área endémica de esta infección con cuadro clínico y hallazgos laboratoriales compatibles con enfermedad por dengue con signos de alarma. Durante la hospitalización, cursa con hemoptisis e insuficiencia respiratoria produciendo su posterior fallecimiento. Conclusión: Es importante reconocer la hemorragia alveolar difusa como parte del compromiso respiratorio por dengue y diferenciarlo de otras posibilidades infecciosas y no infecciosas para poder brindar el manejo adecuado de forma temprana.

Background: Dengue virus infection is an endemic disease in some regions of Peru. Most of these cases are classified as dengue without warning signs and the reported mortality is less than 1%. However, there are certain conditions associated with the disease that could increase mortality. We Case report:present the case of a 48-year-old female patient from a dengue endemic area with clinical and laboratory compatible with dengue disease with warning signs. During hospitalization, she presents hemoptysis and respiratory insufficiency, leading to death. It is important to recognize diffuse alveolar Conclusion:hemorrhage as part of dengue respiratory manifestations and to differentiate it from other infectious and non-infectious possibilities in order to provide appropriate and early management.

Laryngeal Tuberculosis in Pregnant Women: A Case Report and Review of the Literature.

Tuberculosis is the most frequent granulomatous disease but the involvement of the larynx is rare. Immunosuppressed patients have a higher risk of developing this clinical form due to primoinfection or reactivation of latent tuberculosis. It is common to confuse the diagnosis of laryngeal tuberculosis with laryngeal cancer because they have similar macroscopic lesions and both produce dysphonia of chronic evolution. We present the case of a pregnant woman with chronic dysphonia, dysphagia, and odynophagia, diagnosed initially with laryngeal cancer after the first laryngoscopy. However, the patient also presented with fever, productive cough, weight loss, and dyspnea. The sputum sample showed a positive result for acid-fast bacilli (AFB) test; chest X-ray was showed bibasal nodular lesions with a predominance of right hemithorax and reticular opacities in left apex. A new laryngoscopy revealed a mamelonated tumor in the arytenoid cartilage, which led to the initiation of the antituberculous treatment without confirming the diagnosis by biopsy, with clinical improvement and no serious sequelae at the end of treatment. The reason for presenting this case is to consider the possibility of tuberculosis in areas of high endemicity, in patients who have a laryngeal tumor of probable neoplastic etiology, and that a biopsy is not necessary for the diagnosis of laryngeal tuberculosis in cases associated with pulmonary symptomatology.
