Coinfections with multiple opportunistic pathogens in this context are uncommon. We describe a rare case of disseminated <i>Nocardia paucivorans</i>, pulmonary <i>Cryptococcus gattii,</i> pulmonary <i>Mycobacterium chelonae</i>, and subsequent PAP in a patient with high-level anti-GM-CSF antibodies. A 64-year-old man presented with subacute bilateral shoulder pain and was diagnosed with acromioclavicular septic arthritis. <i>N. paucivorans</i> was isolated, and subsequent evaluation demonstrated disseminated infection with numerous brain abscesses, left eye endophthalmitis and pulmonary involvement. Interval computed tomography of the chest revealed new right lower lobe consolidation, a biopsy of which identified <i>C. gattii</i> and <i>M. chelonae</i>. Immunological testing confirmed high-level anti-GM-CSF antibodies. The patient received prolonged combination antimicrobial therapy, including meropenem, ceftriaxone, linezolid, trimethoprim-sulfamethoxazole, moxifloxacin, fluconazole, tigecycline and clofazimine, with clinical and radiological improvement of infectious lesions. Despite microbiological clearance, progressive bilateral ground-glass opacities developed on serial chest imaging consistent with PAP, with no pathogens identified on bronchoscopic sampling. Given minimal respiratory symptoms, PAP-directed therapy was deferred. The patient remains clinically stable on trimethoprim-sulfamethoxazole prophylaxis with ongoing clinical and radiological surveillance.

The patient, diagnosed as HIV-1 positive, was started on antiretroviral therapy, which had to be modified due to poor adherence. HIV-RNA was extracted from plasma with QIAGEN RNA kit, and nested polymerase chain reaction was performed in Reference National Laboratory of Health Program Fighting Against AIDS in Benin on the polymerase gene using the Applied Biosystems HIV-1 Genotyping Kit PR-RT with Integrase. Drug resistance mutations and the remaining effective antiretrovirals drug were identified using Stanford University Antiretroviral-Associated Resistance Mutation Interpretation Algorithm (https://hivdb.stanford.edu/ Version 9.8). The phylogenetic tree was constructed using SeaView with the maximum likelihood method and 1000 bootstrap iterations to identify the viral subtype along PR-RT and integrase gene. No PI-associated resistance mutations were observed. The NRTIs and NNRTIs associated resistance mutations were (M41 ML, D67G, S68G, K70R, M184 V, T215F, and K219E), (V179E and Y188 L), respectively.

Silver-Russell syndrome, also a rare genetic condition, involves intrauterine growth restriction and multiple metabolic and physical abnormalities that could potentially worsen prognosis after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This study analyzed five hospitalized patients in Brazil, two with Berardinelli-Seip syndrome and three with Silver-Russell syndrome, with confirmed COVID-19. The results showed that most patients presented respiratory symptoms and peripheral oxygen saturation below 95% at admission. Among the cases, two required intensive care and two required noninvasive ventilatory support. Four patients were discharged, while one 19-year-old patient with Berardinelli-Seip syndrome, who had multiple comorbidities and was unvaccinated, died. Symptom onset preceded hospitalization by 2-8 days in Berardinelli-Seip and 2-7 days in Silver-Russell patients. Time from symptom onset to outcome ranged from 6 to 10 days. Hospital stays were short (2-6 days). No Berardinelli-Seip patient required intensive care unit admission; two Silver-Russell patients required brief intensive care unit stays. Overall progression remained under 2 weeks. The study did not identify a consistent association between COVID-19 severity and the presence of these two syndromes, although regular multidisciplinary follow-up may have contributed to favorable outcomes in patients with Silver-Russell syndrome. Despite diagnostic and data-source limitations, the findings suggest that these rare conditions were not uniformly associated with poor outcomes, contrary to initial expectations.
