Lymphopenia of a group of uremic patients was associated with normal percentages of T cells but reduced percentages of B cells. Lymphocyte counts improved after a period of maintenance hemodialysis, although not to control levels, and B cell percentages returned towards normal. Uremia is therefore associated with depression of total T and B cell numbers, with a relatively more pronounced effect on B cells. A period of maintenance hemodialysis produces increase in numbers of both cell types and depression becomes nonselective.

In acute as well as chronic renal insufficiency significant immunological abnormalities were found: diminution of delayed hypersensitivity skin reactions, lymphopenia, reduction of the absolute but not relative number of peripheral blood T-lymphocytes. Responses of lymphocytes from uremic patients to PHA, allogeneic cells, or antigens were normal when lymphocyte cultures were preformed in allologous serum from a healthy individual. Sera from uremic patients had an inhibitory or toxic effect on stimulation of normal lymphocytes. Such an in vitro inhibitory activity was found not only in the whole serum but also when certain substances retained in renal failure (methylguanidine, larger molecules, etc.) were added in the lymphocyte cultures.

We examined the prevalence of clinical and immunologic features of systemic lupus erythematosus (SLE) by race, sex and age in a population-based study of 265 SLE patients. Patients fulfilled the American College of Rheumatology classification criteria. The median time between diagnosis and study enrollment was 13 months. The clinical and hematologic data were limited to occurrences up to 6 months after the diagnosis date, as documented in medical records. We used sera collected at study enrollment from 244 (92%) patients for serologic testing of autoantibodies. The associations between clinical and immunological features of SLE and age, sex and race were examined using logistic regression. The effect of each of these variables was examined adjusting for the other two demographic factors. Mean age at diagnosis was 6 years younger among African-Americans and other minorities compared with white patients (P < 0.01). Discoid lupus, proteinuria, anti-Sm and anti-RNP autoantibodies were more commonly seen in African-American patients, with odds ratios higher than 3.0. Photosensitivity and mucosal ulcers were noted less often in African-American patients. Proteinuria, leukopenia, lymphopenia and thrombocytopenia were approximately three times more common in men compared with women. The prevalence of oral or nasal ulcers and anti-DNA autoantibodies declined with age. The extent to which the differences we observed reflect genetic or environmental influences on the disease process should be investigated.

Systemic lupus erythematosus (SLE) is known to occur in all populations across the globe. In many respects SLE is similar across regions in its spectrum of clinical features, but the severity of the disease and comorbidity are appreciably different in the developing and industrialized worlds. Although data on the prevalence of SLE among Africans and Asians living in the tropics are limited, SLE is reportedly more common and more severe in people of African and Asian extraction living in industrialized countries. Renal disease is especially common in SLE patients in the developing world and is a major cause of morbidity and mortality. Discoid lupus and lymphopenia are frequent clinical features of SLE in patients of African extraction. Thrombotic complications and associated anti-phospholipid antibodies are less common in the Chinese and Black African SLE patients than in Caucasian patients. High frequencies of antibodies to extractable nuclear antigens, especially anti-Sm and anti-U1RNP, have been reported in SLE patients in many developing countries. Infections, including tuberculosis, are among the most important causes of comorbidity and mortality in SLE across all regions of the developing world. With a few exceptions, survival rates for SLE patients in developing countries are substantially lower than those reported in industrialized countries, with early death from infection and active disease. The bimodal pattern of mortality observed in many industrialized countries, is also less evident. While the poorer outcome in developing countries is partly related to inherent genetic differences, better outcomes can be achieved if new initiatives are undertaken to define the burden of disease, increase public awareness, and establish algorithms for diagnosis and treatment based on the available resources and local health-care delivery systems.

By April 26, 2020, infections related to coronavirus disease 2019 (COVID-19) affected people from 210 countries and caused 203,818 reported deaths worldwide. A few studies discussed the outcome of COVID-19 in kidney transplant recipients. This short series demonstrates our experience in managing COVID-19 disease in renal transplant patients in the absence of strong evidence. We report 8 cases of kidney transplant recipients infected with COVID-19 (median age = 48.5 years; range = 21-71 years), including 4 males and 4 females. The most frequently associated comorbidity was hypertension. The most common presenting features were fever and cough. The main radiological investigation was a portable chest X-ray. Other common features included lymphopenia, high C-reactive protein, and a very high ferritin level. Overall, 1 patient was managed as an outpatient, the remaining 7 required hospital admission, 1 of them referred to the intensive therapy unit. Management included supportive treatment (intravenous fluid therapy, monitoring renal function, and symptomatic treatment with or without ward-based oxygen therapy depending on oxygen saturation) and discontinuation of the antiproliferative immunosuppressive drugs. Seven patients recovered and discharged home to self-isolate. One patient required intensive care treatment and mechanical ventilation. Supportive treatment could be sufficient for the management or to be tried first. We also found that short hospital stay with self-isolation on discharge reduces the burden on the health service and protect the staff and the public.
