Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes an ongoing outbreak of respiratory illness called coronavirus disease 2019 (COVID-19). The clinical course could be ranging from mild to severe illness especially the individuals with an immunocompromised condition such as solid organ transplant recipients.

We described a family cluster of COVID-19 patients who were admitted during 3rd April2020 to 30th April 2020. COVID-19 was confirmed by a presence of SARS-CoV-2 ribonucleic acid in the respiratory specimens detected by a qualitative, real-time reverse transcription-polymerase chain reaction. The study focused on the clinical course and management of our cases.

A family cluster of four laboratory-confirmed COVID-19 patients, one of those carried an underlying kidney transplant (KT) receiving immunosuppressants. Clinical presentation and severity of our case series are variable depending on each individual immune status. By far, a KT recipient seems to develop more severity despite antiviral therapy, cessation of immunosuppressant, and aggressive intensive care support.

Our case series plausibly affirmed a person-to-person transmission and potentially severe disease in the transplant population. Clinicians who are encountering with transplant recipients should be aware of possible transmission among family members.

Spontaneous pneumothorax shows a bimodal age distribution, with the secondary peak including patients aged ≥50 years. The purpose of this study was to clarify the etiology and prognosis of spontaneous pneumothorax in the elderly.

Patients aged ≥50 years who were admitted to a tertiary university hospital between 2006 and 2016 due to spontaneous pneumothorax were retrospectively investigated.

Among 136 consecutive patients aged ≥50 years with spontaneous pneumothorax (mean age, 70 years; 114 men), 124 (91%) had underlying lung diseases, including pulmonary emphysema (42%) and interstitial pneumonia (27%). The median period of thoracic drainage was longer (14 days) in the cases with interstitial pneumonia than in the cases of primary pneumothorax (4 days; P < 0.001) and emphysema (9 days; P < 0.005). Eighteen patients (13%) died within 180 days after the onset of pneumothorax. The mortality rate was highest in the cases with interstitial pneumonia (27%) and was mostly associated with infectious compving systemic corticosteroids. Different treatment strategies are warranted for patients with interstitial pneumonia-related pneumothorax. Galunisertib Geriatr Gerontol Int 2020; 20 878-884.
Limited research has been published on the recurrence of Helicobacter pylori infection and risk factors in Chinese children. Our study aimed to identify risk factors for Helicobacter pylori infection recurrence after successful eradication in children.

A prospective, nested case-control study was performed. A cohort of 230 children with successful eradicationofHelicobacter pylori in Baoding (China) was selected from January 2018 to February 2019. A standardized questionnaire was used to obtain socioeconomic details. Eradication regimens and Helicobacter pylori antibiotic susceptibility testing results were also recorded. Interleukin-1β level, interferon-γ level, and genetic susceptibility (IFNGR1 and PTPRZ1 gene polymorphisms) were analyzed. All children were followed for 1year.

Among 218 (94.8%) children who were successfully followed, 41 children (18.8%) had a Helicobacter pylori infection recurrence. The recurrence rate was higher in children ≤10years old than >10years old (22.8% vs 7.1%, P=.01). cobacter pylori infection recurrence.
The Helicobacter pylori infection recurrence rate is high in children in Baoding region and is closely correlated to socioeconomic factors. The IFNGR1 gene polymorphism may be an independent risk factor for Helicobacter pylori infection recurrence.Pathogenic variants in the gene HGSNAT (heparan-α-glucosaminide N-acetyltransferase) have been reported to underlie two distinct recessive conditions, depending on the specific genotype, mucopolysaccharidosis type IIIC (MPSIIIC)-a severe childhood-onset lysosomal storage disorder, and adult-onset nonsyndromic retinitis pigmentosa (RP). Here we describe the largest cohort to-date of HGSNAT-associated nonsyndromic RP patients, and describe their retinal phenotype, leukocyte enzymatic activity, and likely pathogenic genotypes. We identified biallelic HGSNAT variants in 17 individuals (15 families) as the likely cause of their RP. None showed any other symptoms of MPSIIIC. All had a mild but significant reduction of HGSNAT enzyme activity in leukocytes. The retinal condition was generally of late-onset, showing progressive degeneration of a concentric area of paramacular retina, with preservation but reduced electroretinogram responses. Symptoms, electrophysiology, and imaging suggest the rod photoreceptor to be the cell initially compromised. HGSNAT enzymatic testing was useful in resolving diagnostic dilemmas in compatible patients. We identified seven novel sequence variants [p.(Arg239Cys); p.(Ser296Leu); p.(Phe428Cys); p.(Gly248Ala); p.(Gly418Arg), c.1543-2A>C; c.1708delA], three of which were considered to be retina-disease-specific alleles. The most prevalent retina-disease-specific allele p.(Ala615Thr) was observed heterozygously or homozygously in 8 and 5 individuals respectively (7 and 4 families). Two siblings in one family, while identical for the HGSNAT locus, but discordant for retinal disease, suggest the influence of trans-acting genetic or environmental modifying factors.
